                                     PART I


Item 1. Business.

General

     Corporate Realty Income Fund I, L.P. ("Registrant") is a Delaware limited
partnership organized on November 25, 1985 pursuant to the Delaware Revised
Uniform Limited Partnership Act. The general partners of Registrant are 1345
Realty Corporation, a Delaware corporation (the "Corporate General Partner"),
and Robert F. Gossett, Jr. (the "Individual General Partner") (collectively, the
"General Partners"). The limited partners of Registrant are hereinafter
collectively referred to as the "Limited Partners."

     Registrant's business consists of owning and leasing to others the
properties described in Item 2 below. Starting in September 1996, Registrant
leveraged its properties and used the financing proceeds to acquire additional
commercial properties, as described below.

     On March 26, 1986, Registrant commenced an offering (the "Offering") of
$80,000,000 of depositary units of limited partnership interest (the "Units").
Registrant terminated the Offering in September 1987, having issued 3,200,000
Units ($80,000,000) and received net proceeds from the Offering (after deduction
for organization and offering expenses of $5,948,103) aggregating $74,051,897.
Since the Offering, Registrant has invested aggregate funds in excess of
$100,000,000 (including $40,000,000 of financing proceeds) in acquiring and
improving its properties, which currently number seven.

     Rental revenue from the following tenants at Registrant's properties each
accounted for more than 10% of Registrant's total rental revenue for each of the
years ended December 31, 1994, 1995 and 1996:

     a. For 1994, The Austin Company ("Austin") as a tenant in the Austin Place
Building (19%); James River Corporation of Nevada, Inc. ("James River") as a
tenant in the James River Warehouse (20%); and Mesa Operating Limited
Partnership ("Mesa") as assignee of Tenneco Oil Company ("Tenneco"), the tenant
under the original lease for the Marathon Oil Building (24%). In addition, in
1994, Registrant received cash in the aggregate amount of $3,657,374 from the
redemption and sale of securities issued by National Gypsum Company ("Gypsum"),
a tenant in the Austin Place Building, pursuant to Gypsum's bankruptcy
reorganization plan. Registrant realized gain on Gypsum securities in the amount
of $930,750, which amount, if included in rental revenue, would have
approximated 11% of total rental revenue.

     b. For 1995, GTE Directories Corporation ("GTE") as tenant for the
Directory Building (16%); Austin as a tenant in the Austin Place Building (16%);
James River as tenant in the James River Warehouse (16%); and Mesa, the tenant
under the original lease to Tenneco for the Marathon Oil Building (20%).


<PAGE>



     c. For 1996, GTE as tenant for the Directory Building (25%); Austin as a
tenant in the Austin Place Building (29%); and James River as tenant in the
James River Warehouse (16%).

     In 1996, Registrant first extended and increased its secured, revolving
line of credit and then replaced such financing with a new first mortgage
line-of-credit loan, the proceeds of which were used to finance the purchase of
an office building in New York, New York. In February and March, 1997,
Registrant sold the James River Warehouse and used the proceeds from such sale
to purchase an office building in San Antonio, Texas.

     In March 1996, Registrant obtained an extension of its secured credit line
from PNC Bank, N.A., to September 30, 1996, and a $2,000,000 increase in the
maximum principal amount of such credit facility (to $9,800,000). Registrant
paid a loan fee in the amount of $24,500 in connection with this transaction.
This loan bore interest at a variable rate equal to one-half percent (0.5%)
above the lender's prime rate and required monthly payments of interest only.
The PNC Bank loan was secured by a first mortgage lien on the GE Medical Systems
Office Building, the Directory Building, the Austin Place Building, and the
James River Warehouse and a negative pledge agreement (an agreement not to sell
or encumber without the lender's consent) with respect to the Flatiron Building
and the Marathon Oil Building.

475 Fifth Avenue

     On December 6, 1996, Registrant purchased the land, building and other
improvements commonly known as 475 Fifth Avenue, and situated in New York, New
York, from Metropolitan Life Insurance Company ("Met Life"), pursuant to the
terms of a Sale Agreement dated as of November 13, 1996. The property contains a
multi-tenant office building comprised of approximately 240,000 square feet and
is located on the southeast corner of 41st Street and Fifth Avenue in New York
City; Registrant owns fee title to 475 Fifth Avenue, subject to the lien of the
Fleet Bank loan, described below.

     475 Fifth Avenue is a 24-story office building with approximately 20,000
square feet of retail space on the first floor, 210,400 square feet of office
space, and 4,400 square feet of basement space. As of March 6, 1997,
approximately 86% of the rentable square footage in the building was leased
(including approximately 86% of the office space, 85% of the retail space, and
54% of the basement space), at an average current base rent of approximately
$24.55 per square foot (approximately $22.37 per square foot of office space and
$50.86 per square foot of retail space). Following is a schedule of the
expirations of such leases.

     Registrant intends to seek increases in rental income from 475 Fifth Avenue
by leasing vacant space, attempting to convert some office space to additional
retail space, and upgrading the building's facilities and appearance. Over the
next five years, Registrant expects to refurbish the lobby, upgrade the heating
and electrical systems, replace the windows, and repair the roof and exterior
facade. The cost of such improvements and necessary tenant improvements is
expected to aggregate approximately $2,000,000 over such five-year period.
Registrant expects to initially fund such improvements from working capital and
loan drawdowns, and eventually from anticipated increased rental income from the
building.

     475 Fifth Avenue is situated in the Grand Central district of the New York
City midtown market. Such district includes 84 buildings with approximately
49,800,000 aggregate rentable square feet, of which approximately 13.6% is
currently vacant. Asking rents in this district average approximately $35.50 per
square foot. The entire midtown market includes 261 buildings with approximately
165,800,000 aggregate rentable square feet, an approximate 11.9% vacancy rate,
and average asking rents of approximately $37.40 per square foot. Registrant
expects asking rents of approximately $27.75 (including electric charges) per
square foot for 475 Fifth Avenue.

     The purchase price paid by Registrant for 475 Fifth Avenue, including
capitalized closing and related costs, was $27,439,998. The purchase price was
paid as follows: (i) the sum of $3,000,000.00 was paid as a downpayment prior to
closing; (ii) the

c:\crif\10-K.97

                                        3

<PAGE>



amount of $77,025.00 was credited to the purchase price in consideration of
Registrant indemnifying Met Life against a pending action in New York Supreme
Court; and (iii) the balance of $24,362,973.00 was paid at closing. The purchase
price was financed from proceeds of a first mortgage loan from Fleet Bank,
National Association, as described below.

     The $27,439,998 purchase price for 475 Fifth Avenue has been allocated
$5,488,000 to the land and $21,951,998 to the building and improvements.

Fleet Bank Loan

     On September 26, 1996, Registrant obtained a first mortgage line-of-credit
loan (the "Loan") from Fleet Bank, National Association (the "Bank") in the
initial maximum amount of $24,000,000. On such date, Registrant borrowed
$11,200,000 under the Loan and simultaneously satisfied in full the existing
$9,800,000 secured, revolving line-of-credit loan made by PNC Bank, N.A. The
balance of proceeds borrowed by Registrant on such date were used to fund the
Bank's front-end fee, a broker's commission, and other closing costs and to
provide approximately $500,000 in working capital.

     On November 13, 1996, Registrant borrowed an additional $3,000,000 under
the Loan to fund the downpayment made to Met Life upon execution of the Sale
Agreement for the purchase of 475 Fifth Avenue. On December 6, 1996, the terms
of the Loan were amended, including an increase in the maximum loan facility to
$44,000,000, and the amount borrowed was increased to $40,000,000 to fund
Registrant's purchase of 475 Fifth Avenue and to pay additional front-end fees,
broker's commission, and closing costs. On March 17, 1997, the terms of the Loan
were further amended to add the Alamo Towers in San Antonio, Texas as a project
securing the Loan (see "Alamo Towers" below in this Item 1). As of March 26,
1997, the outstanding principal balance of the Loan was $39,715,200.

     The Loan is evidenced by a Secured Promissory Note, a Loan Agreement, an
Environmental Compliance and Indemnification Agreement, a First Amendment of
Loan Agreement and Note, and a Second Amendment of Loan Agreement (collectively,
the "Loan Agreements"). The Loan is secured by a first mortgage lien, an
assignment of rents, a security agreement, and a fixture filing on and from each
of Registrant's properties, including the improvements, equipment, furnishings,
proceeds, books and records, and all payments related thereto, which consists of
the following seven properties: the GE Medical Systems Office Building; the
Directory Building; the Austin Place Building; the Flatiron Building; the
Marathon Oil Building; 475 Fifth Avenue; and the Alamo Towers.

     The Loan matures on September 24, 2000 and the Bank is not required to fund
any advances after September 30, 1999. The Loan requires payment of a front-end
fee in an amount equal to one and one-half percent (1.5%) of the amount of the
total loan commitment,


c:\crif\10-K.97

                                        4

<PAGE>



which amounts have aggregated $660,000 to date. In addition, commencing March
26, 1997 and thereafter for each six month period ending September 30 and March
31, Registrant must pay an unused loan commitment fee equal to one-half percent
(0.5%) of the difference between the average maximum loan commitment for the
period and the average outstanding principal balance of the Loan for such
period.

     The Loan bears interest on each advance of funds from the date of such
advance at the Bank's Peg Rate, plus one-half percent (0.5%) per annum or, if
Registrant so chooses, at the LIBOR rate (offered rates for Eurodollar deposits)
or other market rate offered to the Bank (any such rate, a "Fixed Rate"), plus
two percent (2.0%) per annum. The Peg Rate is the rate announced from time to
time by the Bank as a means of pricing some of its loans to customers (not
necessarily the lowest rate actually charged to any customer class or category).
Registrant may elect to pay interest based on a Fixed Rate on the whole or a
portion of the outstanding principal amount, upon notice to the Bank, but only
in amounts of at least $1,000,000 and in additional integral multiples of
$100,000. As of March 26, 1997, the Peg Rate was 8.5% (interest using this rate
would be at 9.0%) and the 180-day Fixed Rate was 5.9% (interest using this rate
would be at 7.9%). The aggregate outstanding balance of the Loan as of March 26,
1997 bears interest at rates ranging from 7.4375% (on $28,627,200) to 8.0% (on
$10,950,000) to 9.0% (on $138,000), all but the last of which reflect
Registrant's election to base interest on LIBOR rates.

     The Loan requires monthly payments of interest plus principal payments
equal to 1/500th of the then outstanding principal balance. The Loan may be
prepaid at any time, on notice, in whole or in part (a minimum of $1,000,000 and
additional integral multiples of $100,000). Any such prepayment will be without
premium or penalty with respect to funds bearing interest based on the Peg Rate
or, if the prepayment is made on the last day of the applicable interest period,
with respect to funds bearing interest based on a Fixed Rate; however, a
prepayment at any other time of funds bearing interest based on a Fixed Rate
will require payment of a breakage fee, which guarantees the Bank a fixed rate
yield maintenance tied to United States Treasury obligations for the period from
the date of prepayment to the end of the applicable interest period. Amounts
repaid to the Bank may be reborrowed by Registrant provided, however, that
amounts repaid in monthly amortization payments and amounts repaid on account of
475 Fifth Avenue may not be reborrowed.

     Any payments not received by the Bank within 10 days after the due date
will incur a late charge equal to four percent (4%) of the amount of such
payment. Overdue amounts, whether at maturity, by acceleration, or otherwise
will bear interest at a rate equal to four percent (4%) above the otherwise
applicable interest rate.

     The Loan Agreements contain continuing covenants regarding Registrant's
financial condition and the conduct of its operations. Registrant's debt service
coverage ratio (the ratio of cash from


c:\crif\10-K.97

                                        5

<PAGE>



operations to a constant loan amortization payment) cannot be less than 1.40 to
1.0 and its loan to value ratio (the ratio of the outstanding principal balance
of the Loan to the appraised value of its properties) cannot exceed fifty-five
percent (55%). In addition, Registrant must maintain a liquid net worth (cash,
short-term investments, and marketable securities) of at least $2,000,000. The
Loan Agreements also provide that Registrant may distribute to its partners up
to 90% of the sum of its operating net income plus depreciation and
amortization. Registrant must also obtain the Bank's consent, not to be
unreasonably withheld or delayed, to any lease of 10,000 or more rentable square
feet (5,000 square feet for 475 Fifth Avenue and Alamo Towers).

     The Bank's mortgage lien against any of Registrant's properties will be
released only upon payment of an amount equal to 110% of the loan amount
allocated to such property. In addition, such lien will be released only if
Registrant's remaining properties satisfy the debt service coverage ratio and
loan to value ratio.

     Upon the occurrence of an event of default under the Loan Agreements (which
includes the failure to make any payment within 10 days of the due date thereof
and a failure to comply with its financial covenants which continues for 60
days), the Bank may enforce one or more of its remedies, including the right to
(i) declare all principal and interest on the Loan to be due and payable
immediately, (ii) require any or all of Registrant's properties (including all
equipment, fixtures, agreements, and other rights and interests relating
thereto) to be sold at auction to the highest bidder, and (iii) collect any and
all rents from the properties.

     Registrant has also agreed to indemnify and hold harmless the Bank and its
officers, directors, employees, agents, representatives, contractors and
subcontractors, and their respective successors and assigns from and against any
and all claims, liability, costs, and expenses arising out of the presence
and/or clean-up of hazardous materials on or affecting Registrant's properties.

James River Warehouse

     On February 28, 1997, Registrant sold the land, buildings, and other
improvements commonly known as the James River Warehouse, and situated in
Woodland, California, to Pacific Gulf Properties, Inc., pursuant to the terms of
a Purchase and Sale Agreement dated as of February 5, 1997, as amended on
February 21, 1997. The James River Warehouse contains approximately 570,000 net
rentable square feet, is used for general warehousing, distribution, and office
purposes, and is net leased to James River Corporation of Nevada, Inc.

     The sale price for the James River Warehouse was $12,875,000, exclusive of
closing costs and commissions aggregating approximately $225,313 which were paid
by Registrant. The purchase price was paid as follows: (i) the sum of
$300,000.00 was paid as

an earnest money deposit prior to closing; (ii) the amount of $131,998.00 was
credited to the purchase price on account of deferred maintenance required for
the property; and (iii) the balance of $12,443,002.00 was paid at closing.

     Registrant acquired the James River Warehouse in October 1987 for a
purchase price of approximately $14,551,456, inclusive of acquisition fees. At
the time of its sale, Registrant had a tax basis of approximately $11,500,000 in
this property and resulting gain for tax purposes of approxmately $1,000,000.
The net proceeds of the sale of the James River Warehouse have been reinvested
in the Alamo Towers property described below.

Alamo Towers

     On March 17, 1997, Registrant purchased the land, building and other
improvements commonly known as the Alamo Towers, and situated in San Antonio,
Texas, from St. Paul Properties, Inc. pursuant to the terms of a Purchase and
Sale Agreement dated as of January 28, 1997 and amended on February 19, 1997.
The Alamo Towers contains a multi-tenant office building comprised of
approximately 196,000 square feet. Registrant owns fee title to the Alamo
Towers, subject to the lien of the Loan.

     The Alamo Towers is a 9-story office building with approximately 195,000
square feet of office space and 900 square feet of basement space. As of
February 18, 1997, approximately 75% of the rentable square footage in the Alamo
Towers was leased, at an average current base rent of approximately $11.93 per
square foot. Additional space aggregating approximately 9% of the rentable
square footage was used by the prior owner as non-rented offices for its own
use, which space will be largely available to Registrant for leasing. Following
is a schedule of the expirations of such leases.

     Registrant does not expect the property to require significant expenditures
for capital improvements over the next five years.

     The San Antonio office market includes approximately 18,300,000 aggregate
rentable square feet, of which approximately 12% is currently vacant. Asking
rents in this market range from approximately $12-$15 per square foot. The
north-central San Antonio market includes approximately 3,450,000 aggregate
rentable square feet, of which approximately 10% is vacant and for which asking
rents range from approxmately $13 to $15 per square foot.

     The purchase price paid by Registrant for the Alamo Towers, including
capitalized closing and related costs, was $12,002,375. The purchase price was
paid as follows: (i) the sum of $200,000.00 was paid as a deposit prior to
closing; and (ii) the balance of $11,802,375.00 was paid at closing. The
purchase price was financed from proceeds of the sale of the James River
Warehouse, as described above.

     The $12,002,375 purchase price for the Alamo Towers has been allocated
$2,840,000 to the land and $9,162,375 to the building and improvements.

Financing Policies

     The General Partners expect to approximate Registrant's original intention
of a loan to value ratio of 50%. Accordingly, it is expected that Registrant's
total borrowings will approximate 50% of the sum of (i) the appraised values of
its five remaining original properties plus (ii) the purchase price of
additional properties acquired by Registrant. Registrant is not limited by its
Partnership Agreement as to borrowing for any individual property; the aggregate
borrowings on all properties may not exceed an amount equal to the sum of (x)
60% of the aggregate purchase price of all properties which are not refinanced
plus (y) 80% of the aggregate value of all refinanced properties. As of March
17, 1997, Registrant had a loan to value ratio of approximately 47% to 52%.

     The Loan has enabled Registrant to acquire additional properties, but has
increased the risk of loss on its properties. To be profitable, Registrant's
properties must generate cash flow in amounts sufficient to not only cover
operating expenses but also to pay all financing costs.

     Registrant's objectives in making its investments continue to be to (i)
preserve and protect Registrant's capital; (ii) provide long term capital
appreciation, generating long term capital gains for federal income tax purposes
upon sale of the properties; (iii) build up equity through the reduction of
mortgage loans encumbering the properties; and (iv) provide cash distributions
from operations which may be partially tax-sheltered. There is no assurance that
these objectives will be achieved.

Competition

     The Directory Building is fully leased to a single tenant on a net lease or
substantially equivalent basis and does not face competition from other
properties during the terms of such lease. The Austin Place Building and the
Flatiron Building are also currently fully leased. However, upon termination of
these and any other leases, and for any of Registrant's other properties,
Registrant does, and will continue to, compete with other properties for
tenants. Depending upon market conditions and occupancy rates at the time and
place of any vacancies in Registrant's properties, there is currently and there
may be, in the future, intense competition in obtaining tenants to fill such
vacancies. Furthermore, such competition has resulted and may result, because of
reduced rental rates and required concessions to tenants, in decreases in the
rental revenue received by Registrant and capital outlays necessary to fund
tenant improvements. See Item 2 - "Properties" for a discussion of market
conditions in the areas in which Registrant currently competes for tenants.

Employees

     Registrant currently employs six persons, which number is expected to
increase to 14 within the next month as a result of the acquisition of the Alamo
Towers. The business of Registrant is managed by the General Partners. See Item
10 - "Directors and Executive Officers of the Registrant" and Item 13 - "Certain
Relationships and Related Transactions."

Item 2. Properties.

GE Medical Systems Office Building

     On July 10, 1986, Registrant acquired the GE Medical Systems Office
Building, located in Monterey Park, California, for approximately $4,182,000,
inclusive of acquisition fees. Registrant owns fee title to the GE Building and
its 90,000 square feet of underlying land, subject to the lien of the Loan (See
Item 1. - "Business-Fleet Bank Loan"). The property was built in 1985 and
contains 20,250 net rentable square feet, of which approximately 60% is office
space and the remainder is warehouse space. General Electric Company ("GE")
leases 10,600 square feet in the building, on a net lease basis, until October
31, 2000. Annual net rent is $95,400 ($9.00 per square foot); GE also reimburses
Registrant for its proportionate share of operating expenses. In 1996,
Registrant reimbursed GE approximately $125,000 for tenant improvements
necessitated by GE's decision to vacate the other 9,650 square feet in the
building. Registrant is seeking a tenant for the vacant portion (47.7%) of the
property. The building contains an unusually high percentage of office space for
a mixed use property, but Registrant prefers to avoid reconfiguring the space,
both to avoid the construction cost and to obtain the higher rent for office
space.


c:\crif\10-K.97

                                        9

<PAGE>


     Market conditions in the Monterey Park area have improved recently but
still have declined from those prevailing at the time GE executed its initial
lease for the building. The vacancy rate for commercial properties in such area
approximates 17% to 18% for office buildings and 6% to 7% for industrial space.
The GE Building is situated next to a 200,000 square foot Public Storage
facility which, like the GE Building, consists of a front office with warehouse
space in the rear. Such facility is currently 92% occupied; rents approximate
$8.50 per square foot. Rents for mixed office/warehouse space in this area
generally approximate $7.50 to $8.25 per square foot. Registrant can expect to
fund tenant improvements and leasing commissions in connection with leasing any
vacant space in the GE Building. Such expenditures are expected to be funded out
of working capital or, if necessary, out of loan proceeds. See Item 7 -
"Management's Discussion and Analysis of Financial Condition and Results of
Operations - Liquidity and Capital Resources."

The Directory Building (formerly, the IBM Building)

     On October 27, 1986, Registrant acquired the Directory Building, located in
Las Colinas, Texas, for a purchase price of $24,580,375, inclusive of
acquisition fees. Registrant owns fee title to the Directory Building and its
6.67 acres of underlying land, subject to the lien of the Loan. The Directory
Building was built in 1982 and contains approximately 152,100 net rentable
square feet (reduced from 154,300 square feet during IBM's tenancy).

     The building is 100% leased to GTE pursuant to a lease dated as of April
20, 1994, as subsequently amended by amendments dated as of July 29, 1994 and as
of February 22, 1995. The initial term of the lease expires on September 30,
2000, subject to a five-year renewal option at a rate equal to 95% of the then
market rate.

     The amended lease requires approximate monthly rent of $167,500 through
August 31, 1997; and $173,800 from September 1, 1997 through September 30, 2000.
GTE must also pay additional rent equal to excess electric charges and operating
expenses over base levels.

     In connection with the GTE lease, Registrant has expended approximately
$2,628,000 for tenant improvements.

     The Las Colinas office market includes approximately 11,860,000 leasable
square feet, of which approximately 95% was leased as of December 31, 1996.
Weighted average rental rates for such properties approximate $19.50 per square
foot.

Austin Place Building

     On December 30, 1986, Registrant acquired the Austin Place Building, a
two-wing office building located in South Plainfield, New Jersey, for a purchase
price of approximately $16,473,000, inclusive of acquisition fees. Registrant
owns fee title to the

                                       10


<PAGE>



Austin Place Building and its underlying five acres of land, subject to the lien
of the Loan. The property was built in 1986 and contains approximately 105,000
net rentable square feet for use as a multi-tenant facility (reduced from
108,000 square feet as a single tenant facility).

     As of March 15, 1997, the property is fully leased, with 45,700 square feet
leased to Austin (as discussed below) and the remainder at an average current
rent of approximately $17.20 per square foot. Such other leases expire on June
30, 1997 (approximately 4,100 square feet), February 1998 (approximately 17,300
square feet), December 2000 (approximately 17,900 square feet), and May 31, 2007
(approximately 21,650 square feet). South Plainfield is included in the Route
287 submarket (approximately 6,900,000 square feet of which 17% is vacant), the
Somerset County area (approximately 10,260,000 square feet, of which 15% is
vacant), and the Central New Jersey Profit Center (approximately 45,840,000
square feet, of which 15% is vacant). Average rents for office space in such
area approximate $17.50 to $18.45 per square foot. Registrant has expended
approximately $2,205,000, including approximately $10,000 in 1996, for tenant
improvements on the space originally leased to Gypsum.

     Austin's lease is for 45,700 square feet and expires on December 31, 2001.
It requires monthly rent payments of $92,009, adjusted to reflect consumer price
index changes. Austin's lease also requires it to pay Registrant an amount equal
to the operating costs of its allocable share of the property. Austin has
vacated its space but has continued to make its lease payments in full. Austin
has approached Registrant to discuss terminating its lease; because Austin's
lease requires rent payments at a rate which is approximately 75% above
prevailing rates, Registrant would require a substantial payment from Austin to
terminate such lease. Any such payment would be used to fund tenant improvements
and offset lower rents from any replacement leases.

The James River Warehouse (formerly, the Crown Zellerbach Warehouse)

     On February 28, 1997, Registrant sold the James River Warehouse (formerly,
the Crown Zellerbach Warehouse). See Item 1 - "Business-James River Warehouse."

Flatiron Building (formerly, the Cadnetix Building)

     On January 5, 1988, Registrant acquired the Flatiron Building, located in
Flatiron Industrial Park, Boulder, Colorado, for $9,003,085, inclusive of
acquisition fees. Registrant owns fee title to the Flatiron Building and its 5
acres of underlying land, subject to the lien of the Loan. The property contains
approximately 96,070 net rentable square feet for use as a multi-tenant facility
(reduced from 102,000 square feet as a single tenant facility).


c:\crif\10-K.97

                                       11

<PAGE>



     As of March 15, 1997, Registrant has rented all available space in the
building to various tenants pursuant to leases providing for an average current
rent of approximately $9.05 per square foot (exclusive of expenses). Such leases
expire in 1997 (approximately 3,370 square feet), in 1998 (approximately 81,880
square feet), and in 2001 (approximately 10,820 square feet). Market conditions
in the Boulder area remain favorable for owners of commercial buildings. The
market for the Boulder area contains approximately 6.5 million square feet of
commercial space of which approximately 5% is vacant. Average rents for office
space in such area range from approximately $8.50 to $12.00 per square foot,
exclusive of expenses. Registrant has expended approximately $455,000, none of
which was in 1996, for tenant improvements for the Flatiron Building.

Marathon Oil Building (formerly, the Tenneco Building)

     On March 21, 1988, Registrant acquired the Marathon Oil Building (formerly,
the Tenneco Building), an office building located in Oklahoma City, Oklahoma,
for approximately $10,736,200, inclusive of acquisition fees. Registrant owns
fee title to the Marathon Oil Building with its 6.1 acres of underlying land,
subject to the lien of the Loan. The property contains 90,925 net rentable
square feet on two floors, plus a 10,016 square foot basement.

     Marathon and its affiliate, Delhi Gas Pipeline Corporation ("Delhi"), lease
62,625 square feet (including 4,344 in the basement) and 24,704 square feet
(including 567 in the basement), respectively, in the building. Marathon's lease
expires in 2001, subject to two five-year renewal options; Delhi's lease expires
in 1998, with an option to extend for three additional years.

     Annual rent under such leases is approximately $750,600 ($8.75 per square
foot, plus $6.00 per square foot for basement space). Marathon and Delhi must
also pay additional rent equal to their proportionate share of any increases in
operating costs of the building after 1996. Registrant funded tenant
improvements of approximately $350,000 for Marathon and Delhi in 1996.

     Registrant leased approximately an additional 5,600 square feet in the
building in January 1997 for a five-year term at a rent of $11.00 per square
foot. The remaining space (approximately 3.2% of the office space, plus
approximately 51% of the basement) is vacant and Registrant is seeking a tenant
for such space.

     Market conditions in the northwest section of Oklahoma City have recently
improved, although they have declined from those prevailing at the time Tenneco
executed its lease for the building. Such market contains approximately 4.8
million square feet of commercial space of which approximately 8% is vacant.
Average rents for commercial space range from $9.00 to $17.00 per square foot.
Registrant has incurred tenant improvements of approximately $71,000 in 1997 and
can expect to fund tenant improvements and leasing commissions in connection
with leasing any remaining vacant

space in the Marathon Oil Building. Such expenditures are expected to be funded
out of working capital or, if necessary, out of loan proceeds. See Item 7 -
"Management's Discussion and Analysis of Financial Condition and Results of
Operations - Liquidity and Capital Resources."

475 Fifth Avenue

     On December 6, 1996, Registrant acquired 475 Fifth Avenue in New York, New
York. See Item 1 - "Business - 475 Fifth Avenue."

Alamo Towers

     On March 17, 1997, Registrant acquired the Alamo Towers in San Antonio,
Texas. See Item 1 - "Business-Alamo Towers."

Item 3. Legal Proceedings.

     Registrant does not know of any material legal proceedings, other than
ordinary immaterial routine litigation incidental to its business, pending
against or involving Registrant or any of its properties.

Item 4. Submission of Matters to a Vote of Security-Holders.

     There were no matters submitted to a vote of Limited Partners or
Unitholders and none were required to be submitted during the fourth quarter of
the fiscal year covered by this report through the solicitation of proxies or
otherwise.

                                     PART II

Item 5. Market for Registrant's Securities and Related Security- Holder Matters.

     The Units of Registrant are not traded in any established public trading
market. Because of certain provisions of the Internal Revenue Code of 1986, as
amended (the "Code"), as described below, the General Partners have not applied
to include the Units for quotation or listing on any national or regional stock
exchange or any other established securities market.

     The General Partners have adopted a Unit Repurchase Plan, pursuant to which
Registrant may, in its discretion, purchase outstanding Units. Any such
purchases are made at prices no higher than the lowest current independent offer
quotation. During 1996, Registrant repurchased 84,778 Units at a price of $10.75
per Unit.

     Provisions found in Section 7704 of the Code have an adverse impact on
investors in a "publicly traded partnership" ("PTP"). A PTP is a partnership
whose interests are traded on an established securities market or readily
tradeable on a secondary market (or the substantial equivalent thereof). If
Registrant were classified as a PTP, (i) Registrant may be taxed as a
corporation or (ii) income derived from an investment in Registrant would be
treated as non-passive income.

     The IRS has established alternative safe harbors that allow interests in a
partnership to be transferred or redeemed in certain circumstances without
causing the partnership to be characterized a PTP. Although the Units are not
listed or quoted for trading on an established securities market, it is possible
that transfers of Units could occur in a secondary market in sufficient amount
and frequency to cause Registrant to be treated as a PTP. To the extent that any
proposed transfer of Units in secondary market transactions would exceed a safe
harbor volume limitation, the proposed transfer will be restricted pursuant to a
policy adopted by Registrant. Such a restriction could impair the ability of an
investor to liquidate its investment quickly and thus, possibly prevent the
reclassification of Registrant as a corporation pursuant to Code Section 7704.
It is anticipated that Registrant's policy will remain in effect until such
time, if ever, as further clarification of Code Section 7704 permits Registrant
to lessen the scope of its policy.

     The General Partners, if so authorized, will take such steps as are
necessary, if any, to prevent the reclassification of Registrant as a PTP.

     As of March 25, 1997, there were 3,068 Unitholders of record.

     There are no material legal restrictions upon Registrant's present or
future ability to make distributions in accordance with the provisions of
Registrant's Agreement of Limited Partnership, as amended through the date of
this report. However, the Loan Agreements limit distributions to 90% of the sum
of cash from operations, depreciation and amortization. See, however, Item 7
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" for a discussion of economic conditions affecting Registrant's
ability to make distributions in the future.

Item 7. Management's Discussion and Analysis of Financial Condition and Results
        of Operations.

Liquidity and Capital Resources

     At December 31, 1996, Registrant had cash and receivables of approximately
$2,565,000 and a liquid net worth (excess of current assets over current
liabilities) of approximately $535,000. Registrant expects sufficient cash flow
to continue to be generated from operations to meet its current operating and
debt service requirements on a short-term and long-term basis. The Loan also
provides a source of additional capital should Registrant's working capital and
cash flow prove inadequate.

     The expiration of the GE Medical Systems Office Building lease in October
1995 and the Marathon Oil Building lease in February 1996 placed additional
demands on Registrant's capital resources and liquidity. Registrant was obliged
to fund tenant improvements and leasing commissions to re-lease such buildings.
Registrant expended approximately $489,000 on tenant improvements during 1996
for such buildings. Registrant's acquisition of 475 Fifth Avenue and the Alamo
Towers provide the opportunity to increase rental revenues but at the cost of
tenant improvements and leasing commissions for new tenants. In addition,
Registrant expects to make significant capital improvements to 475 Fifth Avenue
over the next five years. See "Item 1. Business - 475 Fifth Avenue."

     To date, Registrant has funded its capital requirements from the Loan and,
previously, out of working capital and through reductions in distributions to
partners. Registrant's quarterly distribution to partners for each of the four
quarters of 1996 was $0.30 per Unit. Registrant intends to maintain this level
of distributions through 1997 and, if possible, thereafter. However, to the
extent Registrant's sources of capital are inadequate for its requirements,
Registrant may need to reduce or suspend distributions to partners, incur
additional indebtedness, and/or dispose of one or more of its properties.

     The Loan has provided Registrant with available capital to acquire
properties, fund improvements and leasing commissions, repurchase outstanding
Units, and otherwise fund capital requirements. The cost of such financing
ultimately must be offset by increased property revenues or Registrant's
operations and capital will be compromised. Upon maturity of the Loan in 2000,
Registrant anticipates satisfying the Loan out of the proceeds of a refinancing
or a sale of assets.

     Registrant has used working capital reserves provided from the net proceeds
of the Offering, loan proceeds, and any undistributed

c:\crif\10-K.97

                                       16

<PAGE>



cash from operations as its primary source of liquidity. Registrant generally
intends to distribute its distributable cash from operations to Unitholders.
However, such distributions are subject to suspension or reduction to meet
capital requirements and are also limited by the Loan Agreements to 90% of cash
from operations plus depreciation and amortization.

Results of Operations

1996 versus 1995

     Rental revenues in 1996 decreased slightly from 1995 primarily as a result
of the expiration of Tenneco's original lease for the Marathon Oil Building in
February 1996 and the subsequent leasing of less than all of such space to
Marathon and Delhi at lower rents. Other income dropped significantly from 1995
to 1996, reflecting the receipt in 1995 of $227,000 of other income attributable
to Gypsum (a former tenant of the Austin Place Building) and Registrant's
receipt in 1995 of a large real estate tax refund attributable to the Austin
Place Building.

     Interest expense in 1996 increased from 1995, primarily because of the
replacement of the PNC Bank loan with the greater amount of the Fleet Bank loan.
Depreciation increased because of additional tenant improvements made by
Registrant and the purchase in December 1996 of 475 Fifth Avenue. Amortization
increased in 1996 primarily due to financing costs incurred in connection with
the Fleet Bank loan. The acquisition of 475 Fifth Avenue in December 1996 is
largely responsible for the increase in property operation expenses.
Professional fees decreased in 1996 in comparison to the increased level of due
diligence investigations of possible property acquisitions in 1995. General and
administrative expenses increased in 1996 primarily due to significant due
diligence expenses incurred by Registrant in 1996 in investigating possible
property acquisitions which were not ultimately consummated.

     Net income was $677,914 in 1996 as compared to $2,008,688 in 1995. After
adjusting for non-cash items (principally deferred revenue, depreciation, and
amortization), operations generated cash flows of approximately $3,620,000 in
1996 and $4,160,000 in 1995.

1995 versus 1994

     Rental revenues in 1995 increased from 1994 primarily as a result of GTE's
full occupancy of the Directory Building in 1995 as contrasted to the vacancy
and partial occupancy of such building in 1994. Such increase in rental revenues
was partially offset by the recognition in 1994 of approximately $958,000 in
gain from Gypsum securities as compared to the receipt in 1995 of approximately
$227,000 of other income attributable to Gypsum.

     Interest expense in 1995 increased over 1994, reflecting higher rates of
interest under the Loan. Depreciation increased because of additional tenant
improvements made by Registrant. Property operating expenses increased from 1994
to 1995 primarily

c:\crif\10-K.97

                                       17

<PAGE>

because the Directory Building was not fully utilized in 1994. Management fees
increased in 1995, reflecting the increase in adjusted cash from operations and
the fees attributable to replacement leases. Professional fees increased in 1995
primarily as a result of due diligence investigations of possible property
acquisitions following Unitholder approval of Registrant's plan to acquire
additional properties. General and administrative expenses increased in 1995,
primarily reflecting inclusion of Registrant's employees for a full year in
1995.

     Net income was $2,008,688 in 1995 as compared to $2,450,563 in 1994. After
adjusting for non-cash items (principally deferred revenue, depreciation, and
amortization), operations generated cash flows of approximately $4,160,000 in
1995 and $2,202,000 in 1994.

Inflation

     In the past, inflation has not had a material impact on Registrant's
operations or financial condition, as certain leases of Registrant's properties
provide for increases in rents based on changes in the consumer price index, and
other leases provide lease payments that escalate over time. Registrant's
properties with performing leases are protected by arrangements whereby the
tenants pay to Registrant an amount equal to all or a portion of the operating
costs of the properties, with Registrant's share of expenses, if any, subject to
a predetermined limit. These arrangements help to insulate Registrant from the
effects of any increases in operating costs. However, to the extent that there
is vacant space or nonperforming leases at any of the Registrant's properties,
Registrant lacks this protection against inflation, particularly with regards to
increased expenses that are not reimbursed.

Item 12. Security Ownership of Certain Beneficial Owners and Management.

     As of March 15, 1997 no person was known by Registrant to be the beneficial
owner of more than five percent (5%) of the outstanding Units of Registrant.

     As of March 15, 1997, neither the Individual General Partner nor the
Corporate General Partner nor any of its directors or officers owned any Units
of Registrant.

     Robert F. Gossett, Jr., the Individual General Partner and an officer and
director of the Corporate General Partner, and Pauline G. Gossett, an officer of
the Corporate General Partner, own all of the outstanding capital stock of the
Corporate General Partner.


Item 13. Certain Relationships and Related Transactions.

     Registrant has and will continue to have certain relationships with the
General Partners and their affiliates as discussed below.

     The General Partners received $37,589 ($30,071 to the Corporate General
Partner and $7,518 to the Individual General Partner) as their allocable share
(1%) of adjusted cash from operations with respect to the year ended December
31, 1996. For the year ended December 31, 1996, $6,779 (1%) of Registrant's net
income was allocated to the General Partners ($5,423 to the Corporate General
Partner and $1,356 to the Individual General Partner).

     The General Partners or their affiliates are also entitled to receive: a
partnership management fee for managing the affairs of Registrant, equal to 7%
of adjusted cash from operations less the asset management fee; an asset
management fee for managing Registrant's funds which are not invested in
properties, equal to 0.5% per annum of the average amount of outstanding funds
during each calendar month which are not otherwise invested in properties; and a
property management fee for property management services for Registrant's
properties, equal to the normal and competitive fees customarily charged by
unaffiliated parties rendering similar services in the same geographic area, not
to exceed 1% of the annual gross revenues for leases with terms of ten years or
more or 6% of the annual gross revenues for replacement leases. During the year
ended December 31, 1996, the General Partners earned and were paid an aggregate
of $565,519 of such management fees ($452,415 to the Corporate General Partner
and $113,104 to the Individual General Partner). At December 31, 1996, all of
such fees had been paid.

     The General Partners are also entitled to receive leasing commissions in
connection with leasing, releasing or leasing related services performed on
behalf of the Registrant in connection with the negotiation of tenant leases.
Such fees are

c:\crif\10-K.97

                                       21

<PAGE>



computed at a rate equal to 3% of the gross revenue for the first five years of
each lease signed where the General Partners performed such leasing services.
During the year ended December 31, 1996, the General Partners were paid an
aggregate of $110,584 ($88,467 to the Corporate General Partner and $22,117 to
the Individual General Partner).

     During the year ended December 31, 1996, the General Partners were also
entitled to reimbursement for expenses incurred in connection with Registrant's
operations aggregating $166,036 ($132,829 to the Corporate General Partner and
$33,207 to the Individual General Partner).

standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material respects, the financial position of Corporate Realty Income Fund I,
L.P. as of December 31, 1996 and 1995 and the results of its  operations and its
cash flows for each of the years in the  three-year  period  ended  December 31,
1996, in conformity with generally accepted accounting  principles.  Also in our
opinion,  the related financial statement schedule,  when considered in relation
to the basic financial  statements  taken as a whole,  presents  fairly,  in all
material respects, the information set forth therein.

                      CORPORATE REALTY INCOME FUND I, L.P.
                        (A Delaware limited partnership)

                          NOTES TO FINANCIAL STATEMENTS

                        December 31, 1996, 1995 and 1994


1.   ORGANIZATION

     Corporate  Realty Income Fund I, L.P. (the  "Partnership")  was formed as a
limited  partnership  on  November  25,  1985  under  the  laws of the  State of
Delaware.  The  Partnership  was formed for the purpose of acquiring  and owning
income-producing  commercial and industrial real estate  properties for lease to
others.  The  Partnership  will  terminate  on December  31, 2010 or sooner,  in
accordance with the Partnership Agreement.

     The general  partners of the Partnership are 1345 Realty  Corporation,  the
corporate general partner,  and Robert F. Gossett,  Jr., the individual  general
partner.

     On November 30, 1994, all of the outstanding capital stock of the corporate
general partner was acquired by the individual  general partner in a transaction
which was  effective as of July 1, 1994.  As a result of this  acquisition,  the
entire interest of the general partners is controlled by the individual  general
partner.

     The initial capital was $1,025 representing capital contributions of $1,000
by the general partners and $25 by the original limited partner. The Partnership
commenced  operations on June 2, 1986 with the acceptance of  subscriptions  for
1,082,640 Depositary Units of limited partnership  interests (the "Units").  The
Partnership  has  authorized  the  issuance  of  up  to  4,000,000   Units.  The
Partnership sold 3,200,000 Units, representing $80,000,000,  which completed the
offering.  Upon the first  admittance  of the  additional  limited  partners and
unitholders, the original limited partner withdrew from the Partnership.

     During 1996 and 1995,  respectively,  84,778 and 72,116 units were redeemed
from limited partners and cancelled.

2.   SIGNIFICANT ACCOUNTING POLICIES

     The Partnership's records are maintained on the accrual basis of accounting
for financial reporting and tax reporting purposes.

     Depreciation  of buildings  for  financial  reporting  purposes is computed
under the straight-line  method over an estimated  economic useful life of forty
years.  Depreciation  of buildings  for tax purposes is determined in accordance
with the Accelerated Cost Recovery System.

     Acquisition  fees in connection  with investment  properties  acquired have
been capitalized as a cost of the property upon acquisition.

     Deferred financing costs are being amortized using the straight-line method
over the term of the associated loan.


                                      F-8

2.   SIGNIFICANT ACCOUNTING POLICIES (continued)

        In accordance with the Statement of Financial  Accounting  Standards No.
13 (SFAS No. 13),  "Accounting  for Leases," the Partnership  recognizes  rental
income on a  straight-line  basis over the fixed term of the lease period.  Step
rent receivables  represent  unbilled future rentals.  The following  reconciles
rental income received in cash to rental income recognized:

                                              1996         1995          1994
                                          ----------    ----------    ----------
Rental income billed to tenants           $8,941,250     8,583,897     7,440,419
Step rent receivables                        160,361       543,871       476,909
                                          ----------    ----------    ----------
Rental income recognized                  $9,101,611     9,127,768     7,917,328
                                          ==========    ==========    ==========

     Offering  costs are  nonamortizable  and have been  deducted  from  limited
partners' capital.

     No  provision  for income  taxes has been made since all items of income or
losses and tax  benefits  are  passed  through to the  individual  partners.  At
December 31,  1996,  the net  difference  between the tax bases and the reported
amounts of assets and liabilities was $14,367,316.

     The  Partnership  Agreement  provides that net income shall be allocated to
each calendar  month of the year and shall be  apportioned on a monthly basis to
the holders of interests in the ratio in which the number of interests  owned by
each limited  partner or  unitholder  on the first day of the month bears to the
total number of interests  owned by the limited  partners and  unitholders as of
that date.

     The amount of net income per limited  partnership unit was calculated using
the weighted  average number of units  outstanding  of 3,087,170,  3,184,222 and
3,200,000 in 1996, 1995 and 1994, respectively.

     Short-term  investments,  which consist  principally of money market funds,
are  carried  at cost which  approximates  market  value.  For  purposes  of the
statements of cash flows, the Partnership considers short-term investments to be
cash equivalents.

     SFAS No.  107,  "Disclosures  about Fair Value of  Financial  Instruments,"
defines  fair  value of a  financial  instrument  as the  amount  at  which  the
instrument could be exchanged in a current  transaction between willing parties.
The Partnership's cash and short-term investments, accounts receivable and notes
receivables,  deposits,  accounts payable and accrued expenses, interest payable
and mortgage loan payable are carried at cost, which approximates fair value.

     The Partnership adopted the provisions of SFAS No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of," on
January 1, 1996.  This  Statement  requires that  long-lived  assets and certain
identifiable  intangibles be reviewed for impairment  whenever events or changes
in  circumstances  indicate  that the  carrying  amount  of an asset  may not be
recoverable.  Recoverability  of  assets  to be held and used is  measured  by a
comparison  of the carrying  amount of an asset to future net cash flow expected
to be generated by the asset. If such assets are considered to be impaired,  the
impairment  to be  recognized  is measured  by the amount by which the  carrying
amount of the  assets  exceeds  the fair  value.  Assets to be  disposed  of are
reported at the lower of the  carrying  amount or fair value less costs to sell.
No  impairment  losses  were  required  on any of the  properties  owned  by the
Partnership.

2.   SIGNIFICANT ACCOUNTING POLICIES (continued)

     The  general  partners  have made a number  of  estimates  and  assumptions
relating  to the  reporting  of assets and  liabilities  and the  disclosure  of
contingent  assets and  liabilities  to prepare  these  financial  statements in
conformity with generally accepted accounting  principles.  Actual results could
differ from those estimates.

3.   PARTNERSHIP AGREEMENT

     The Partnership  Agreement provides that profits,  losses and distributions
shall be allocated 99% to the limited partners and 1% to the general partners.

     Sale or  refinancing  proceeds  will  generally be  distributed  99% to the
limited  partners and 1% to the general partners until the limited partners have
received an amount which,  when added to all prior  distributions  of cash, will
equal  their  original   invested  capital  plus  an  8%  per  annum  cumulative
noncompounded return. Thereafter,  after payment of the subordinated disposition
fee,  proceeds will be  distributed  75% to the limited  partners and 25% to the
general partners.

     Taxable  income and tax loss generally will be allocated 99% to the limited
partners and 1% to the general partners.

years ended December 31, 1996,  1995 and 1994  escalation  charges  amounting to
$1,765,433,  $1,735,411  and  $1,728,374,  respectively,  have been  included in
rental income.

6.   TRANSACTIONS WITH GENERAL PARTNERS AND AFFILIATES

     The general partners or their affiliates receive a property  management fee
equal to either 1% in the case of a long-term net lease or 6% for other types of
leases on the gross revenue from the property,  and a partnership management fee
equal to 7% of adjusted cash from operations,  as defined,  and reimbursement of
administrative  expenses.  The general partners also receive leasing commissions
in connection with leasing,  re-leasing or leasing related services performed on
behalf of the  Partnership in connection  with the negotiation of tenant leases.
Such  commissions  are computed at a rate equal to 3% of the gross  revenues for
the first  five years of each  lease  signed  where the  general  partners  have
performed such leasing services.

     Following is a summary of the fees earned and reimbursable expenses for the
years ended December 31, 1996, 1995 and 1994:

                                              1996          1995          1994
                                            --------      --------      --------

Partnership management fees                 $263,577      $271,302      $203,636
Property management fees                     301,942       285,729       113,451
Administrative expenses                      166,036       133,393        66,049
                                            ========      ========      ========

In 1996 and 1995,  respectively,  leasing  commissions  of $110,584 and $243,113
were billed to the  Partnership  by the  general  partners  and  recorded by the
Partnership as deferred leasing commissions on the balance sheet.

7.   LOAN PAYABLE

     In March 1996, the Partnership  extended the $7,800,000 line of credit from
PNC Bank, N.A. (the "Lender") for an additional  six-month period which ended on
September  30, 1996.  In connection  with this  extension,  the structure of the
indebtedness was changed from a term loan to a secured revolving line of credit.
Interest only was payable  monthly on the first day of each calendar  month with
all unpaid  interest and  outstanding  principal  due on September  30, 1996. In
connection with the extension of the loan, the Partnership paid fees of $24,500.
The loan was  secured by a deed of trust  given with  respect to the  Directory,
James River,  Austin Place and GE properties.  In September  1996, this loan was
repaid with the proceeds of a new line of credit obtained from Fleet Bank.

On September 26, 1996, the Partnership  entered into a loan agreement with Fleet
Bank, N.A. The purpose of the loan was to refinance the existing indebtedness to
PNC Bank,  to provide  working  capital  for  tenant  improvements  and  leasing
commissions  with respect to the  properties  owned by the  Partnership,  and to
provide funds for the acquisition of additional properties.

7.   LOAN PAYABLE (continued)

The terms of the loan  agreement,  as amended,  provide for a term of four years
and maximum gross  borrowings  of  $44,000,000.  Borrowings  under the loan bear
interest  monthly at a rate,  selected at the option of the  Partnership  at the
time of the associated borrowing, based on (i) the lender's Peg Rate (as defined
in the loan  agreement)  plus .50% or (ii) the  applicable  LIBOR  rate or other
market rate offered to the bank plus 2%. The loan requires monthly  amortization
of principal in an amount equal to 1/500th of the outstanding  principal  amount
of the loan on the first day of the applicable month with a final payment of the
then  outstanding  balance  at  maturity.  The loan may be  prepaid at any time.
Borrowings  under the loan agreement are secured by all of the properties of the
Partnership. Upon the sale of any property, the Partnership is required to repay
principal on the total indebtedness under the loan in an amount equal to 110% of
that portion of the  outstanding  balance of the loan  attributable  to the sold
property, as defined in the loan agreement.

Through  December 31, 1996, the Partnership had borrowed  $40,000,000  under the
loan,  of which  $39,955,200  was  outstanding  at December 31,  1996,  at rates
ranging from 7.6% to 8.87%.

In  connection  with this loan,  the  Partnership  incurred fees and expenses of
$1,522,626, which have been capitalized and are being amortized over the term of
the loan agreement.

on demand. All interest calculations provided for herein shall be made on the
basis of a 360-day year and the actual number of days elapsed; provided,

     (b) Notwithstanding anything herein or in the Loan Agreement to the
contrary, Lender shall have no obligation to make advances of the Loan at any
time after September 30, 1999.

     3. Maturity Date. The outstanding principal of, and all accrued interest

     4. Selection of Rate. (a) Except as provided in PARAGRAPHS 4(b) and 9, the
outstanding Principal Amount shall bear interest at a rate per annum equal to
the Peg Rate plus one-half of one (.50%) per annum.

     (b) Provided there is no Default and/or Event of Default, Borrower may
elect to pay interest on the whole or any portion of the Principal Amount

of the outstanding Principal Amount pursuant to a Fixed Rate Notice. Lender must
receive such Fixed Rate Notice prior to 11:00 A.M., New York City time, on a
Business Day at least two (2) Business Days prior to:

          (i) the last day of an Interest Period (in the case of an outstanding
     Fixed Rate Advance); or

     the case of a conversion of a Peg Rate Advance to a Fixed Rate Advance) for
     the commencement of the applicable Interest Period.

If Borrower fails to give a Fixed Rate Notice at least two (2) Business Days
prior to the end of an Interest Period, then, on the last day of the Interest
Period, the outstanding Fixed Rate Advance shall convert to a Peg Rate Advance.
On the date specified in the Fixed Rate Notice as the date on which the
applicable Interest Period is to begin, Lender shall, by 11:00 a.m., New York
City time, notify Borrower's Authorized Representative by telephone (such notice
to be promptly confirmed in writing), which notice shall specify the date, the
proposed Fixed Rate and the period of time on such date during which such rate
is to be available. If Lender fails to specify the period for which such quoted
rate is available, then such rate shall be deemed to be available only for
thirty minutes from the time Lender, orally or in writing, notifies Borrower's
Authorized Representative of such rate. If Borrower then wishes to obtain such
Loan at such Fixed Rate, Borrower's Authorized Representative shall promptly
give notice to Lender to such effect (the "Fixed Rate Acceptance Notice"), which
notice shall be irrevocable and may be by telephone, promptly confirmed in
writing.

     (c) Without in any way limiting Borrower's obligation to confirm in writing
any telephonic Fixed Rate Notice or Fixed Rate Acceptance Notice, Lender may,
prior to receipt of written confirmation, act without liability on the basis of
telephonic notice which it believes in good faith to be from Borrower and, in
any event, Lender may act without liability on the basis of telephonic or
written notice which it believes in good faith to be from Borrower.

     5. Payment of Interest on and Number of Fixed Rate Advances. If a Fixed
Rate Advance is outstanding, then in addition to the monthly payments of
interest required under PARAGRAPH 2(a) hereof, all accrued and unpaid interest,
if any, on such Fixed Rate Advance shall be due and payable on the last day of
the Interest Period. In no event may there be more than an aggregate of four (4)
Interest Periods in effect at any one time hereunder.

     6. Suspension of Fixed Rate. If Lender, in its sole discretion, determines
that Lender's making or maintaining of a Fixed Rate Advance is unlawful for any
reason, then Lender may suspend the availability of the Fixed Rate and
immediately convert the outstanding Fixed Rate Advance, if any, to a Peg Rate
Advance. Lender shall immediately notify Borrower of any such conversion and
Borrower shall pay to Lender, on demand, (i) all accrued and unpaid interest on
the Fixed Rate Advance to the date of such conversion, plus (ii) such amounts as
Lender shall require to compensate it for the costs of converting any such Fixed
Rate Advance to a Peg Rate Advance (except that

no amounts shall be payable by Borrower under this clause (ii) if, at the
commencement of the applicable Interest Period, it was unlawful for Lender to
have made such Fixed Rate Advance). The certificate of Lender as to any amounts
payable pursuant to this PARAGRAPH shall, absent manifest error, be final,
conclusive and binding on Borrower. No Fixed Rate Notices shall be given by
Borrower thereafter until Lender determines that a Fixed Rate Advance would be
lawful.

     7. Increases in Cost. In the event that at any time or from time to time
any domestic or foreign requirement of law, regulation, order or decree or any
change therein or in the interpretation or application thereof or compliance by
Lender with any request or directive (whether or not having the force of law)
from any governmental, fiscal, monetary or other authority (i) does or shall
subject Lender to any tax, duty, charge or withholding on or from payments due
from Borrower (excluding taxation of the income of Lender and excluding any such
taxes, duties or withholding already taken into account in calculating the Fixed
Rate); or (ii) does or shall impose, modify or hold applicable or change any
reserve (including, without limitation, basic, supplemental, marginal, special
or emergency reserves but not including reserve requirements already taken into
account in calculating the Fixed Rate), special deposit, compulsory deposit or
similar requirement with respect to assets of, deposits with or for the account
of, advances or loans by, or other credit extended by, or any other acquisition
of funds by Lender; or (iii) does or shall impose on Lender any other condition
or change therein and the result of any of the foregoing is to increase the cost
to Lender of making available to Borrower, converting from or to, or maintaining
Fixed Rate Advances, then, and in any such event, Lender shall notify Borrower
in writing of such occurrence setting forth in reasonable detail the basis for
and amounts of such increased costs, and Borrower shall pay to Lender, on
demand, such amounts as will compensate Lender for such increased costs. In such
event, Borrower shall have the option of converting (without an exchange of
funds) such Fixed Rate Advance to a Peg Rate Advance by notice to Lender and
payment to Lender of any sums (other than the principal so converted to a Peg
Rate Advance) which would be payable to Lender pursuant to PARAGRAPH 8 if such
conversion were a prepayment. The certificate of Lender as to any amounts
payable pursuant to this PARAGRAPH shall, absent manifest error, be final,
conclusive and binding on Borrower.

     8. Prepayment. (a) At any time during the term hereof that the Applicable
Rate is based upon the Peg Rate or on a date which is the last day of an
Interest Period

(with respect to the whole or any portion of the Principal Amount as to which
the Interest Period is ending), upon not less than ten (10) Business Days
written notice to Lender specifying the date on which prepayment is to be made,
Borrower shall have the privilege of prepaying the unpaid balance of the
Principal Amount of this Note, in whole or in part, on any Business Day, without
payment of a premium or penalty, provided that (i) any such prepayment shall be
in a minimum amount of not less than $1,000,000 and additional integral
multiples of $100,000, and (ii) together with any such prepayment, Borrower
shall also pay any accrued and unpaid interest on the portion of Principal
Amount of this Note being so repaid to the date of prepayment and all other sums
or charges, if any, then due and owing hereunder or under the Loan Documents.

     (b) (i) At any time during the term hereof that the Applicable Rate is
based upon the Fixed Rate, Borrower shall have the privilege of prepaying the
unpaid balance of the Principal Amount or a portion thereof upon the applicable
notice and in the minimum amounts set forth in PARAGRAPH 8(a) hereof, except
that in addition to the payment of the whole or portion of the Principal Amount
so to be prepaid, all accrued and unpaid interest thereon and all other sums due
hereunder or under the Security Document(s), Borrower shall pay a breakage fee
based on the following formula:

          (a) Upon such prepayment, Lender shall determine whether there is a
     fixed rate yield maintenance premium due by subtracting the Redemption
     Treasury Rate from the Fixed Rate (as such terms are defined below). If the
     Redemption Treasury Rate is equal to or greater than the Fixed Rate, no
     fixed rate yield maintenance fee will be due.

          (b) However, if the Redemption Treasury Rate is less than the Fixed
     Rate, a fixed rate yield maintenance fee will be computed by Lender as
     follows:

                                  (F-R) x P x D
                                  -------------
                                       360

          (c) Lender shall discount the resulting number to the net present
     value thereof, i.e., as if such sum were received in equal monthly
     installments from the date of prepayment to the end of the applicable
     Interest Period, at a rate reasonably determined by Lender. To determine
     present value, the discount shall be calculated on



                                        8


FRK11313.X25

<PAGE>


     the basis of a three hundred sixty-five (365) day year.

          (d) For purposes of computing the fixed rate yield maintenance fee,
     the following definitions govern:

          -"F" or "Fixed Rate" means the applicable Fixed Rate plus two and
          one-quarter (2.25%) percent.

          -"R" or "Redemption Treasury Rate" means, at the time of prepayment,
          the rate of interest per annum equal to the most recently published
          quotations of yields to maturity of U.S. Treasury obligations (bills
          on a discounted basis shall be converted to a bond equivalent), as
          published weekly by the Federal Reserve Board in the Federal Reserve
          Statistical release, trading closest to par value and with a maturity
          date comparable to the end of the applicable Interest Period.

          -"P" means the Principal Amount being repaid.

          -"D" means the number of days remaining until the end of the
          applicable Interest Period.

     Absent manifest error, Lender's calculation of the fixed rate yield
     maintenance premium shall be deemed conclusive.

          (ii) Lender shall notify Borrower of the amount and basis of
     determination of such breakage fees, it being agreed that (A) the
     calculation of such breakage fees shall be based on the most recent
     Redemption Treasury Rate available to Lender; and (B) Lender shall not be
     obligated to have actually reinvested the prepaid amount in any such U.S.
     Government Treasury Obligations as a condition precedent to receiving
     breakage fees calculated pursuant to the provisions of this subparagraph
     (b). Borrower, upon receipt of such notice and simultaneously with any such
     prepayment, shall remit to Lender the breakage fees.

     (c) Any acceleration of the Maturity Date pursuant to any provisions hereof
or of the Loan Documents shall be deemed a voluntary prepayment for the purposes
hereof, and if a Fixed Rate Advance is then outstanding, Borrower shall be
required, on demand, to pay the breakage fees premium, if any, calculated as
aforesaid.

     (d) Any payments of the Principal Amount received by Lender (whether
pursuant to the terms of this PARAGRAPH 8 or otherwise) shall be applied to this
Note in the following order of priority: (i) first, to any accrued interest
which is due and unpaid on this Note as of the date of such payment; and (ii)
second, to the outstanding Principal Amount of this Note in the inverse order of
maturity.

     (e) Except as otherwise provided in SECTION 6.06 of the Loan Agreement, the
Loan and the advances hereunder are not revolving loans and, therefore, Borrower
may not borrow, repay and reborrow hereunder.

     9. Involuntary Rate; Late Charge. Overdue principal and, to the extent
permitted by law, overdue interest and all other overdue amounts owing
hereunder, whether at maturity, upon acceleration or otherwise, shall bear
interest for each day that such amounts are overdue (whether or not any required
notice of default shall have been given) at a rate per annum equal to four
(4.0%) percent per annum in excess of the Applicable Rate in effect from time to
time (such rate the "Involuntary Rate"). In addition, any payment, whether of
principal or interest, not received by Lender within ten (10) days after the
date it is due shall be assessed a late charge of four (4.0%) percent of the
overdue payment (such charge, the "Late Charge"), and such Late Charge shall be
due on demand. Lender's right to receive interest at the Involuntary Rate and
any Late Charge pursuant to this PARAGRAPH shall be in addition to all other
rights and remedies provided herein or by law for the benefit of the holder
hereof upon a default; and the acceptance of the same by the holder hereof shall
not restrict such holder in any respect in the exercise of any other or further
right or remedy, nor shall the same be deemed to be, as to the holder hereof, a
waiver or release of Borrower from any of its obligations herein contained or
constitute an extension of the time for payments due hereunder.

     10. Security. This Note is secured by the Mortgages and all other documents
or agreements or hazardous substance indemnities (including any amendment,
modification, extension or renewal thereof) now or hereafter executed in
connection herewith are collectively referred to herein as the "Security

of this Note, all of which are hereby expressly waived, upon the happening of
any Event of Default or any event by which, under the terms of the Security
Document(s), said unpaid balance may or shall become due and payable. Failure to
exercise any such option at any time shall not constitute a waiver of the right
of the holder hereof to exercise the same in the event of any subsequent default
or acceleration event.

     12. Notices. Except as otherwise provided herein, any notice to be given
hereunder shall be given as provided in the Loan Agreement.

     13. Funding Sources. Nothing contained herein shall be deemed to obligate
Lender to fund advances hereunder in any particular place or manner; and nothing
contained herein shall be deemed to constitute a representation by Lender that
it has funded or will fund advances in any particular place or manner.

     14. Taxes and Attorneys' Fees. Borrower shall pay to Lender, immediately
upon demand, any and all taxes assessed against Lender by reason of its holding
of this Note and the receipt by it of interest payments hereunder (other than

Government, any state or any political subdivision of either thereof on such
interest payments), and any and all other sums and charges that may at any time
become due and payable under the Security Document(s).

     15. No Partnership or Joint Venture. Nothing contained in this Note or
elsewhere shall be deemed or construed as creating a partnership or joint
venture between Lender and Borrower or between Lender and any other person, or
cause the holder hereof to be responsible in any way for the debts or
obligations of Borrower or any other person.

     16. Waiver. Borrower hereby waives diligence, presentment, protest and
demand, notice of protest, dishonor and nonpayment of this Note, and expressly
agrees that, without in any way affecting the liability of Borrower hereunder,
Lender may extend the Maturity Date or the time for payment of any amount due
hereunder, accept additional security, release any party liable hereunder and
release any security now or hereafter securing this Note without in any other
way affecting the liability and obligation of Borrower or any other Person.
Borrower further waives, to the full extent permitted by law, the right to plead
any and all statutes of limitations as a defense to any demand on this Note,
under the Security Document(s), or on any other agreement now or hereafter

     17. Interest Rate Limitation. Notwithstanding anything contained herein to
the contrary, the holder hereof shall never be entitled to receive, collect or
apply as interest on the obligation evidenced hereby any amount in excess of the
maximum rate of interest permitted to be charged by applicable law; and in the
event the holder hereof ever receives, collects or applies as interest any such
excess, such amount which would be excessive interest shall be applied to the
reduction of the Principal Amount; and if the Principal Amount is paid in full,
any remaining excess shall forthwith be paid to Borrower.

     18. Severability. Every provision of this Note is intended to be severable.
In the event any term or provision hereof is declared by a court of competent

     matter arising under this Note, the Loan Agreement or any of the Security
     Documents, whether or not such litigation has been commenced in respect of
     this Note, the Loan Agreement or any of the Security Documents and whether
     or not other persons are also parties thereto, (b) the right to interpose
     any counterclaim therein (other than a mandatory counterclaim), (c) the
     right to have the same consolidated with any other or separate suit, action
     or proceeding, (d) any claim that New York County or such District is an
     inconvenient forum and (e) any claim against Lender for consequential,
     special or punitive damages respecting the Loan Documents. Lender, by its
     acceptance hereof waives trial by jury in any suit, action or proceeding as
     to which Borrower, pursuant to the preceding clause (a) has waived trial by
     jury.

          (c) No delay on the part of Lender in exercising any of its options,
     powers or rights, or partial or single exercise thereof, whether arising
     hereunder, under the Loan Agreement or under the Security Documents or
     otherwise, shall constitute a waiver thereof or affect any right hereunder
     or thereunder. No waiver of any of such rights and no modification,
     amendment or discharge of this Note shall be deemed to be made unless the
     same shall be in writing, duly signed by Lender and Borrower. Each such
     waiver (if any) shall apply only with respect to the specific instance
     involved and shall in no way impair the rights of Lender or the obligations
     of Borrower hereunder in any other respect at any other time.

     22. Set-off. Borrower agrees that, in addition to (and without limitation
of) any right of set-off, bankers' lien or counterclaim Lender may otherwise
have, Lender shall (to the extent permitted by applicable law) be entitled, at
its option, to offset balances held by it for the account of Borrower at any of
its offices, in lawful money of the United States of America or in any other
currency, against any principal of or interest on this Note, or any other
obligation of Borrower held by Lender, which is not paid when due (regardless of
whether such balances are then due to Borrower), in which case Lender agrees, by
acceptance of this Note, to promptly notify Borrower thereof, provided that
Lender's failure to give such notice shall not affect the validity of Lender's
right to offset such balances.

     23. Grid Note. Borrower authorizes Lender to record on SCHEDULE I annexed
hereto the information with respect to the initial advance under this Note and
any payments and prepayments of the Principal Amount made by Borrower and such
notations shall be presumed to be correct and binding subject to rebuttal by
Borrower only by clear and convincing evidence; provided, however, that the
failure of Lender to make any such notation shall not limit or otherwise affect
the obligation of Borrower to repay the Principal Amount nor alter or impair any
of the other obligations of Borrower hereunder, under the Loan Agreement or
under the Security Documents.

     24. Miscellaneous. (a) This Note may not be changed orally but only by an
agreement in writing signed by the party against whom enforcement of any waiver,
change, modification or discharge is sought.

     (b) Should the indebtedness represented by this Note or any part thereof be
collected at law or in equity, or in bankruptcy, receivership or any other court
proceedings (whether at the trial or appellate level), or should this Note be
placed in the hands of attorneys for collection upon default, Borrower agrees to
pay, in addition to the principal, premium, interest and other sums due and
payable hereon, all costs of collection or attempting to collect this Note,
including reasonable attorneys' fees and expenses.

     25. Limitation on Maker's Liability. The provisions of SECTION 6.16 of the
Loan Agreement are hereby incorporated herein by reference.

                                 LOAN AGREEMENT


     LOAN AGREEMENT (as the same may be amended or otherwise modified from time
to time, this "Agreement") is made as of September 26, 1996, between CORPORATE
REALTY INCOME FUND I, L.P., a Delaware limited partnership ("Borrower"), and
FLEET BANK, NATIONAL ASSOCIATION, a national banking association ("Lender").


                                     RECITAL

     Borrower has requested from Lender, and Lender has agreed to provide to
Borrower, the extension of credit for which provision is made herein.

     THEREFORE, Lender and Borrower agree as follows:


                                   ARTICLE I.
                                    THE LOAN

     1.01 Loan. By and subject to the terms of this Agreement and each other
document identified on EXHIBIT A hereto as a Loan Document (this Agreement, such
other document(s), and such amendments thereto as may hereafter be made from
time to time, are herein collectively called the "Loan Documents"), Lender
agrees to loan Borrower up to the principal sum of TWENTY-FOUR MILLION AND
NO/100THS DOLLARS ($24,000,000) ("Loan").


                                   ARTICLE II.
                         REPRESENTATIONS AND WARRANTIES

     Borrower makes the following representations and warranties to Lender as of
the date hereof and continuing thereafter:

     2.01 Authority. To the best of Borrower's knowledge, Borrower has complied
with all laws and regulations concerning its organization, existence and
transaction of business.

     2.02 Enforceability. Borrower is authorized to execute, deliver and perform
its obligations under the Loan Documents, and the Loan Documents are the legal,
valid and binding obligations of Borrower, enforceable in accordance with their
respective terms, except as such enforceability may be limited by bankruptcy,
reorganization, insolvency or


<PAGE>



similar laws generally affecting the enforcement of creditor's rights and by
generally applicable principles of equity.

     2.03 No Violation. To the best of Borrower's knowledge, Borrower's
undertakings under the Loan Documents do not violate any applicable statute,
law, regulation or ordinance or any order or ruling of any court or governmental
entity, or conflict with, or constitute a breach or default under, any agreement
by which Borrower, or any of its assets, is bound or regulated. To the best of
Borrower's knowledge, Borrower is not in violation of any statute, law,
regulation or ordinance, or of any order of any court or governmental entity.
There are no claims, actions or proceedings pending or, to Borrower's knowledge,
threatened against Borrower.

     2.04 Financial Information. All financial information delivered to Lender
with respect to Borrower, including, without limitation, financial information
relating to the Projects, fairly and accurately represents Borrower's financial
condition and the financial condition of the Projects (in each instance as of
the date thereof) and, in the case of the annual financial statements of
Borrower, has been prepared in accordance with generally accepted accounting
principles consistently applied, unless otherwise noted in such information. No
material adverse change in such financial condition has occurred.

     2.05 Accuracy. All reports, documents, instruments and information
delivered to Lender concerning the Loan, any of Borrower's assets or required by
the Loan Documents are accurate, correct and sufficiently complete to give
Lender true and accurate knowledge of their subject matter (in each instance as
of the date thereof), and do not contain any material misrepresentation or
material omission.

     2.06 Taxes. Except as set forth on SCHEDULE 2.06, Borrower has filed all
required federal, state, county and municipal tax returns and has paid all taxes
owed and payable by it, and Borrower knows of no basis for additional assessment
with respect to any taxes.

     2.07 No Subordination. There is no agreement, indenture, contract or
instrument to which Borrower is a party or by which Borrower or any of its
assets may be bound that requires the subordination (a) in right of payment of
any of Borrower's obligations under the Loan Documents to any other obligation
of Borrower and/or (b) in priority of lien of any of the Mortgages to any other
lien upon any of the assets of Borrower.



                                       2
<PAGE>


     2.08 Permits, Franchises. To the best of Borrower's knowledge, Borrower
possesses all permits, memberships, franchises, contracts and licenses required
and all trademark rights, trade names, trade name rights, patents, patent rights
and fictitious name rights necessary to enable it to conduct the business in
which it is engaged without conflict with the rights of others.

     2.09 ERISA. To the best of Borrower's knowledge, Borrower is in compliance
in all material respects with all applicable provisions of the Employee
Retirement Income Security Act of 1974 (ERISA), and no Reportable Event, as
defined in said Act, has occurred and is continuing with respect to any Plan
initiated by Borrower thereunder.

     2.10 Other Obligations. To the best of its knowledge, Borrower is not in
default on any obligation for borrowed money, any purchase money obligation or
any other material lease, commitment, contract, instrument or obligation.

                              CONDITIONS PRECEDENT

     Lender shall not be obligated to make any disbursement or take any other

are satisfied at the time of such disbursement or other action:

     3.01 Compliance. The representations and warranties contained herein shall
be true on and as of the date of such disbursement or other action, with the
same effect as though such representations and warranties had been made on and
as of such date, and on such date no Default (as defined herein) shall exist and
be continuing.

     3.02 Documentation. Prior to such disbursement or other action hereunder,
Borrower shall have delivered to Lender all Loan Documents and such other
documents, instruments, policies, forms of evidence and other materials as may
reasonably be required under the Loan Documents.

disbursement or other action shall be reasonably satisfactory to counsel of
Lender.

     Borrower covenants that so long as any credit remains available under this
Agreement, and until payment in full of all amounts owing by Borrower under the
Loan Documents, Borrower will:

     4.01 Existence. Preserve and maintain its existence and all of its rights,
privileges and franchises; comply with the requirements of all applicable laws,
rules, regulations and orders of any governmental authority; and not change its

Properties (including federal and state income taxes), except such as Borrower
may in good faith contest or as to which a bona fide dispute may arise, provided
provision is made to the reasonable satisfaction of Lender for eventual payment
thereof in the event that it is found that the same is an obligation of
Borrower.

     4.03 Notice. Promptly give notice in writing to Lender of (1) any material
litigation pending or threatened against Borrower; (2) the occurrence of any
breach or default (beyond any applicable notice and cure period) in the payment

entity, other than Lender; (3) any uninsured or partially uninsured loss
(relating to any of the Projects or any of the Additional Properties) occurring
as a result of fire, theft, liability or other casualty; or (4) any termination
or cancellation (without the simultaneous substitution of a replacement policy

Borrower is required herein to maintain under the Loan Documents.

     4.04 Accounting Records. Maintain adequate books and records in accordance
with generally accepted accounting principles consistently applied, and permit
any representative of Lender, at any reasonable time and upon reasonable notice
to Borrower, to inspect, audit and examine such books and records, to make
copies of the same, and to inspect the properties of Borrower.

     4.05 Facilities. Keep all of Borrower's properties which are useful or
necessary to Borrower's business and which are encumbered by the Mortgages, or
any of them, in



                                       4

time make necessary repairs, renewals and replacements thereto so that
Borrower's properties shall be fully and efficiently preserved and maintained.


                                   ARTICLE V.
                                     DEFAULT

     5.01 Default. The following shall constitute a "Default" under the Loan
Documents:

     (a) Payment. The failure of Borrower to pay (i) within ten (10) days after
the same becomes due, any sum payable on account of principal of the Loan and/or
interest thereon and/or (ii) within ten (10) days after written notice that such
fee has not been paid when due, the fee described in SECTION 6.08; or

     (b) Other Payments; Performance. The failure of Borrower (i) to perform
when due any obligation of Borrower under the Loan Documents (other than an
obligation referred to in SECTION 5.01(a)), or (ii) to observe any covenant, the
performance or observance of which is required under any Loan Document; and such
failure described in the preceding clauses (i) or (ii) shall continue for a
period of at least thirty (30) business days after written notice thereof shall
have been given to Borrower by Lender; provided, however, that a Default shall
not be deemed to exist hereunder, if (w) such failure referred to in the
preceding clauses (i) or (ii) is reasonably capable of being cured within a
period of time Lender, in its reasonable discretion, advises Borrower that
Lender deems to be reasonable in the circumstances, which period of time shall
in no event be less than thirty (30) business days from the day of Lender's
notice, (x) Borrower promptly after receipt of a notice of default from Lender
commences and at all times diligently proceeds to cure such failure and (y)
within the time period so prescribed by Lender, Borrower does, in fact cure such
failure; or

     (c) Attachment. The sequestration or attachment of, or any levy or
execution upon, any property of Borrower encumbered by the Mortgages, or any of
them, which is not released, expunged, bonded or dismissed prior to the earlier

sale of the property affected thereby; or

     (d) Performance of Other Obligations. Subject to Borrower's rights under
SECTION 5.03, the occurrence of a breach or default (beyond any applicable
notice and cure



                                       5
<PAGE>


period) in the payment or performance of any obligation imposed by any
instrument or agreement (other than the Loan Documents) pursuant to which
Borrower has borrowed money (in excess of $250,000) from, or incurred liability
(in excess of $250,000) to, any person or entity including Lender; or

     (e) Representations and Warranties. The failure of any representation or
warranty made by Borrower in any Loan Document to be true within fifteen (15)
days after written notice by Lender; provided, however, that a Default shall not
be deemed to exist if (i) such incorrectness is reasonably capable of being
cured within a period of time which Lender, in its sole but reasonable
discretion, advises Borrower that Lender deems to be reasonable in the
circumstances, which period of time shall in no event be less than thirty (30)
business days from the day of Lender's notice, (ii) Borrower promptly after
receipt of a notice of default from Lender commences and at all times diligently
proceeds to cure such default and (iii) within the time period prescribed by
Lender, Borrower does, in fact, cure such default; or

     (g) Involuntary Bankruptcy. Borrower's failure to effect a full dismissal
of any involuntary petition under the Bankruptcy Code or any other Debtor Relief
Law that is filed against Borrower or in any way restrains or limits Lender's
rights under the Loan Documents, prior to the earlier of the entry of any order
granting relief sought in the involuntary petition or sixty (60) days after the
date of filing of the petition; or

     (h) Loan Documents. The occurrence of an "Event of Default" (as defined in
any Loan Document); or

<PAGE>


     (i) Transfers; Management. (i) The direct or indirect sale, transfer,
conveyance or voluntary encumbrance (except for permitted leases and for
releases where Lender receives the required release price, it being understood
and agreed that,in the case of the Additional Properties, no release payment is
required) of any of the Projects or any part thereof of any of the Additional
Properties or any part thereof, except by reason of the transfer of equity
interests in Borrower (provided, however, that Robert F. Gossett, Jr. and
members of his immediate family (i.e., his spouse, children and grandchildren)
and trusts, corporations and other entities controlled by him or his immediate
family or for his benefit or the benefit of his immediate family shall, in the
aggregate, retain the equity interests in Borrower collectively held by such
persons and entities as of June 30, 1996) or (ii) Robert F. Gossett, Jr., other
than by reason of death or disability, ceases to be the managing general partner
of Borrower with substantially all of the management powers he presently
possesses.

     5.02 Remedies. Upon the occurrence of a Default, Lender may, at its option,
declare all sums owing to Lender under the Loan Documents immediately due and
payable; provided, however, that upon the occurrence of a Default specified in
SECTIONS 5.01(f) or 5.01(g), or upon the occurrence of any other Default
specified in any Loan Document where provision is made for acceleration to occur
automatically as a consequence thereof, all sums owing to Lender under the Loan
Documents shall automatically become immediately due and payable. In addition,
upon the occurrence of any Default, (a) the obligation, if any, of Lender to
permit further borrowings under the Loan Documents shall immediately cease and
terminate, and (b) Lender shall have all rights, powers and remedies available
under the Loan Documents, or accorded by law, including without limitation, the
right to resort to any or all security for the Loan, and to exercise any or all
of the rights of a beneficiary or secured party pursuant to applicable law. All
rights, powers and remedies of Lender may be exercised at any time by Lender and
from time to time during the continuation of a Default. All rights, powers and
remedies of Lender in connection with each of the Loan Documents are cumulative
and not exclusive and shall be in addition to any other rights, powers or
remedies provided by law or equity.

     5.03 Right of Contest. Borrower may contest in good faith any claim,
demand, levy or assessment by any person (other than Lender with respect to the
Loan Documents) which would constitute a Default, if (a) Borrower pursues the
contest diligently and in a manner which Lender reasonably determines will not
be prejudicial to Lender nor impair the rights of Lender under the Loan
Documents; and (b) Borrower



                                       7
<PAGE>


deposits with Lender any funds or other forms of assurance which Lender in good
faith from time to time reasonably determines appropriate to protect Lender from
the consequences of the contest being unsuccessful. Borrower's compliance with
this SECTION 5.03 shall operate to prevent such claim, demand, levy or
assessment from becoming a Default.


                                   ARTICLE VI.
                              ADDITIONAL PROVISIONS

     6.01 Note. The Loan shall be evidenced by a promissory note (as the same
may be amended or otherwise modified from time to time, the "Note") in the form
of EXHIBIT B hereto.

     6.02 Purpose. The proceeds of the Loan shall be used for the following
purposes and no others: (i) refinancing (concurrently with the execution and
delivery hereof) secured first mortgage indebtedness of Borrower existing as of
the date hereof in the approximate principal amount of $9,800,000, (ii)
redeeming outstanding equity interests in Borrower (but in no event may more
than $3,000,000 of the Loan be used for this purpose), (iii) paying for tenant
improvements and leasing commissions incurred by Borrower in connection with the
Projects or any of the Additional Properties or any of the Affiliate Properties,
(iv) acquiring Additional Properties in accordance with the requirements of
SECTIONS 6.11 below, (v) paying closing costs incurred by Borrower in connection
with (a) the closing of the Loan (including a commission to Lexham Capital
Partners), (b) the acquisition of Additional Properties by Borrower and (c) the
acquisition of an Affiliate Property by an Affiliate Property Owner, (vi) paying
other costs of owning and operating any of the Projects, the Additional
Properties and/or the Affiliate Properties, or (vii) making any equity
contribution to any Affiliate Property Owner.

     6.03 Maturity. Subject to the limitations, terms and conditions contained
in the Loan Documents, the outstanding principal balance of the Loan, together
with all accrued and unpaid interest and any accrued and unpaid Unused Loan
Commitment Fee, shall be due and payable on September 30, 2000.

     6.04 Advances. Subject to and in accordance with the provisions hereof, the
Loan will be disbursed in a series of advances ("Advances") to Borrower, from
time to time during the period commencing on the date hereof and ending on
September 30, 1999. Advances shall be in minimum amounts of $1,000,000 and
integral multiples of $100,000. The



                                       8
<PAGE>


aggregate total of all Advances outstanding at any time shall never exceed the
principal amount of Twenty-Four Million Dollars ($24,000,000) less any permanent
Loan commitment reductions hereunder, and all borrowings shall otherwise be
subject to all the limitations, terms and conditions contained in the Loan
Documents. Reductions in the Loan Commitment shall occur as a result of the
provisions of SECTIONS 6.06(d) and 6.07(b).

     6.05 Requests for Advances. Borrower shall make a request for each Advance
by completing, executing and delivering to Lender, not less than three (3)
business days prior to the date upon which Borrower wishes Lender to disburse
the Advance, a request for an Advance in form reasonably satisfactory to Lender.
Upon receipt of such a request for an Advance and such other information and
documents regarding the Advance or the purpose for the Advance as Lender may
reasonably request or as may be required hereby, Lender shall disburse such
Advance on the requested date.

     6.06 Borrowing and Repayment. (a) Borrower may from time to time during the
term of the Loan borrow and partially or wholly repay its outstanding
borrowings, subject to all of the limitations, terms and conditions of the Loan
Documents.

     (b) Reborrowings of the Loan must be secured by the Mortgages and, with
respect to such reborrowings, the Mortgages must continue as first priority
liens. Accordingly, as a condition to Borrower's right to borrow hereunder, the
title insurer of the liens of the Mortgages must have so insured that the
Mortgages will, on a first priority basis, secure the Loan. Subject to the
provisions of SECTIONS 6.06(d) and 6.07(b) and the other provisions of the Loan
Documents, Borrower may from time to time reborrow amounts which Borrower has
repaid.

     (c) Advances (including Advances made pursuant to Borrower's right to
reborrow) shall also be conditioned on a clear continuation of title to the date
of each Advance, showing marketable title to the Projects and the Additional
Properties, if any, vested in Borrower, with no exceptions other than those
approved by Lender, and the issuance of such endorsements (if not previously
issued) to the mortgage title insurance policies insuring the continuing first
priority of the liens of the Mortgages as Lender may reasonably require.
Notwithstanding the foregoing, to the extent the mortgage title insurance
policies issued to Lender on the date hereof insure the first lien priority of
future advances without the requirement for a clean



                                       9
<PAGE>


continuation of title, no such continuation of title shall be required.

     (d) The Loan commitment shall be permanently reduced by required monthly
principal payments described in SECTION 6.07(b) and, at the election of
Borrower, by such amounts as Borrower shall elect by written notice to Lender.
If Borrower elects to reduce the Loan Commitment to an amount less than the
outstanding Loan, Borrower's notice making such an election must be accompanied
by a repayment of the Loan (in an amount such that the outstanding Loan does not
exceed the reduced Loan commitment) and by the payment of any amounts due under
PARAGRAPH 8 of the Note as a result of such prepayment.

     6.07 Interest and Amortization. (a) Interest shall accrue upon the
outstanding principal balance of the Loan at the rate(s) provided in the Note,
and such interest shall be payable as required therein.

     (b) Concurrently with each monthly payment of interest under the Loan,
Borrower shall make monthly principal payments to Lender in an amount equal to
the outstanding principal balance of the Loan on the payment date (i.e., on the
first day of each calendar month) divided by 500. Accordingly, the required
monthly principal payment will vary from month to month. Any monthly principal
payments shall reduce the Loan commitment by a like amount and may not be
reborrowed.

     6.08 Unused Loan Commitment Fee. Commencing six (6) months after the date
hereof, Borrower shall pay to Lender a non-refundable unused Loan commitment fee
(the "Unused Loan Commitment Fee") at a rate equal to one-quarter percent (1/4%)
per annum of an amount equal to the average maximum Loan commitment for the
period then ended less the average outstanding principal balance of the Loan for
the period then ended. No Unused Loan Commitment Fee shall be payable in respect
of the six months immediately following the date hereof. The first payment on
account of the Unused Loan Commitment Fee shall be payable on October 1, 1997 in
respect of the period commencing six (6) months from the date hereof to
September 30, 1997, and each subsequent payment of the Unused Loan Commitment
Fee shall be due on the first day of April and October thereafter in respect of
the six-month period then ended.

     6.09 Expenses. Without in any way limiting SECTION 8.01 of this Agreement,
Borrower shall pay Lender immediately upon demand all reasonable costs and
expenses incurred by Lender in connection with: (1) the preparation of any
commitment letter relating to the Loans and any and



                                       10
<PAGE>


all Loan Documents; (2) the enforcement or satisfaction by Lender of any of
Borrower's obligations under this Agreement or under the other Loan Documents;
and (3) the negotiation, preparation and/or execution of any amendment, waiver,
supplement or modification to any of the Loan Documents and any other documents
and instruments prepared in connection therewith, and the consummation of the
transactions contemplated thereby, including, without limitation, the reasonable
fees and disbursements of counsel to Lender. For all purposes of this Agreement,
Lender's costs and expenses shall include, without limitation, all reasonable
legal fees, accounting fees, auditor fees and inspection fees.

     6.10 Collateral; Release of Collateral. (a) The performance of all
obligations of Borrower to Lender under the Loan Documents shall be secured by
the Security Documents (as such term is defined in the Note).

     (b) Lender agrees to release its liens and security interests from one or
more of the Projects if (i) no Default shall exist and no event or circumstance
shall have occurred or arisen (or would occur or arise as a result of such
release) which would constitute a Default but for any unsatisfied requirement
for the giving of notice or passage of time or both, (ii) Borrower pays to
Lender 110% of the Loan allocation for the Project to be released (as provided
for in SECTION 6.10(c)), and (iii) without limiting the foregoing, the remaining
Projects will, immediately after giving effect to the proposed release and any
repayment of the Loan as a result thereof, in the reasonable calculation of
Lender, satisfy the Loan to Value Ratio and Debt Service Coverage Ratio
covenants contained in SECTIONS 6.18. With respect to Additional Properties
which are subjected to the lien of a Mortgage, Lender, without receipt of any
release price, will release an Additional Property upon any bona-fide sale or
refinancing thereof or upon any transfer thereof to an Affiliate Property Owner.

     (c) The Loan allocations for the initial Projects are set forth on EXHIBIT
C hereto. Only if, as and when an Additional Property becomes a Project will
Borrower and Lender adjust the Loan allocations for all of the then Projects on
a basis consistent with that used to establish the Loan allocations for the
initial Projects.

     6.11 Additional Properties. If Borrower desires to use Loan proceeds to
acquire an additional property or an interest therein (an "Additional
Property"), such Additional Property must be reasonably acceptable to Lender.
Borrower's interest in an Affiliate Property Owner is not Additional Property.
Any Additional Property so acquired shall become part of the collateral securing
the Loan (and



                                       11
<PAGE>


Borrower, at its sole cost and expense, shall execute and deliver to Lender such
Mortgages, security agreements and assignments as Lender may reasonably require
in order to subject the Additional Property to a lien in favor of Lender).
Additional Properties shall not be deemed to be "Projects" or be included in the
calculation of the Loan to Value Ratio or Debt Service Coverage Ratio covenants
contained in SECTION 6.18 unless Lender, in its sole and absolute discretion,
consents thereto in writing. In the event that an Additional Property shall, by
reason of such consent by Lender, become a "Project", then such Additional
Property shall be included in the calculation of the Loan to Value Ratio and
Debt Service Coverage Ratio. Upon any acquisition of an Additional Property,
whether or not such Additional Property is to become a Project, Borrower shall
at its cost also deliver to Lender with respect to the Additional Property a
survey, a mortgage title insurance policy and the other items described in
EXHIBIT D hereto. Borrower may transfer Additional Properties to Affiliate
Property Owners, and upon any such transfer the Additional Property so
transferred shall cease to be an Additional Property.

     6.12 Unsecured and Subordinate Financing. Borrower shall not obtain any
unsecured or subordinate secured financing, except for current debt incurred in
the ordinary course of Borrower's business which would be characterized as an
unsecured trade account payable, and for these purposes Lender agrees that
tenant buildout expenses and leasing costs are unsecured trade accounts payable.

     6.13 Single Purpose Entity. Borrower shall at all times remain a single
purpose entity owning only the Projects, any Additional Properties and any
Affiliate Property Owners.

     6.14 Property Information. Borrower shall submit to Lender the following
information:

     (a) Audited annual financial statements of Borrower prepared in accordance
with generally accepted accounting principles consistently applied (including a
detailed Balance Sheet, Income Statement and Cash Flow Statement), to be
submitted to Lender no later than 120 days after the end of each fiscal year of
Borrower.

     (b) Quarterly unaudited financial statements of Borrower prepared in
accordance with generally accepted accounting principles consistently applied
(including a detailed Balance Sheet, Income Statement and Cash Flow Statement,
subject to normal year-end adjustments), to be submitted to Lender no later than
60 days after the end of



                                       12
<PAGE>


each fiscal quarter of Borrower. Such quarterly statements shall be certified by
a general partner of Borrower to be true, correct and complete in all material
respects.

     (c) Upon the request of Lender but not more often than quarterly, lease-up
schedules and/or updated rent rolls and operating statements for the Projects
and any Additional Properties.

     (d) Such other information with respect to the Projects and any Additional
Properties as may be reasonably requested from time to time by Lender.

     6.15 Operating Accounts. Borrower shall maintain all operating accounts for
the Projects and any Additional Properties at the New York Branch of Lender;
provided, however, that Borrower shall be permitted to maintain (other than with
Lender) accounts for the initial deposit of rent payments. On or about the
twentieth of each month, Borrower will transfer the collected rents to such
operating accounts.

     6.16 Limitation on Borrower's Liability. Lender's recovery against Borrower
under the Loan Documents shall be limited solely to the collateral given to
Lender as security for Borrower's performance under the Loan Documents and to
the other assets of Borrower and is otherwise non-recourse to all partners
(limited and general) in Borrower, and such recovery shall not be a lien, or the
basis of a claim of lien or levy of execution, against the assets of any partner
(general or limited) of Borrower. Notwithstanding the foregoing, each general
partner of Borrower and the assets of each general partner of Borrower shall be
fully liable to Lender to the same extent that Borrower's general partner would
be liable absent the foregoing limitation of this paragraph for and to the
extent of any loss or damage suffered by Lender in connection with or as a
result of any of the following, but any such general partner shall only be so
liable for his or its own acts and then only to the extent of any actual loss
caused by such acts: (a) fraud and material misrepresentation; (b) intentional
damage to the Projects or Additional Properties; and (c) misapplication of any
insurance or condemnation proceeds or tenant security deposits or any other
funds maintained by Borrower for any purpose in connection with the Projects or
Additional Properties. The limitations hereof shall not be deemed to limit: (i)
any right Lender might otherwise have to obtain injunctive relief against
Borrower or Borrower's general partner; (ii) any suit or action in connection
with the preservation, enforcement or foreclosure of the liens, mortgages,
assignments and security interests now or at any time hereafter securing the
payment and performance of all



                                       13
<PAGE>


sums and obligations under this Agreement or any of the other Loan Documents; or
(iii) subject to the Loan Documents, the collection of amounts which may become
owing or payable under or on account of insurance, condemnation awards or
damages for other public actions or surety bonds maintained or provided by
Borrower; provided, however, that the assertion by Lender of any such right,
suit, action or collection of amounts shall not result in any claim, demand or
liability against any general partner of Borrower or any claim or demand upon
the assets of any general partner of Borrower except as otherwise provided
herein.

     6.17 Borrower's Distributions. Provided no Default shall exist and no event
or circumstance shall have occurred or arisen which would constitute a Default
but for any unsatisfied requirement for the giving of notice or passage of time
or both, Borrower may distribute to its partners up to ninety percent (90%) of
the sum of its operating net income (as shown on Borrower's financial statements
and calculated in a manner consistent with its statements for the period ending
December 31, 1995) plus depreciation and amortization.

     6.18 Borrower's Covenants. (a) As of the end of each Accounting Period, (A)
the Projects encumbered by the Mortgages must have (i) a Debt Service Coverage
Ratio of not less than 1.40:1.0, and (ii) a Loan to Value Ratio not to exceed
55% (i.e., the appraised value of the Projects shall equal or exceed two hundred
and ten percent of the then outstanding principal balance of the Loan), (B)
Borrower must have a Liquid Net Worth of not less than $1,000,000, and (C)
Borrower's total liabilities (calculated in a manner consistent with Borrower's
financial statements for the period ending December 31, 1995, and including
accounts payable but excluding current unpaid real estate taxes) may not exceed
55% of the appraised value of the Projects and the Additional Properties (based
on appraisals by Lender or appraisals by Borrower approved by Lender). If
Borrower fails to comply with any of the foregoing covenants and such failure
continues for sixty (60) days after written notice thereof by Lender to
Borrower, such failure shall, subject (in the case of a failure by Borrower to
comply with a covenant in SECTION 6.18(a)(A)(i) or (ii) or SECTION 6.18(a)(C))
to the provisions of SECTION 6.18 (b), constitute a Default.

     (b) Within sixty (60) days after Lender's written notice to Borrower of
non-compliance with the covenants contained in SECTION 6.18 (a)(A)(i) or (ii) or
SECTION 6.18(a)(C), Borrower shall have the option (x) in the case of a default
under SECTION 6.18(A)(i) or (ii), to remedy such failure by reducing the
outstanding principal balance



                                       14
<PAGE>


of the Loan to a level such that Borrower is in compliance with such covenants
or (y) in the case of a default under SECTION 6.18(a)(C), to remedy such failure
by reducing Borrower's total liabilities (which may include reducing the
outstanding principal balance of the Loan) to a level such that Borrower is in
compliance with such covenant. Within sixty (60) days after Lender's written
notice to Borrower of non-compliance with the covenants contained in SECTION
6.18(a)(A)(ii) or SECTION 6.18(a)(C), Borrower shall have the option to remedy
such failure by providing cash collateral, a letter of credit and/or additional
collateral acceptable to Lender, in Lender's reasonable discretion, equal to the
amount needed so that Borrower is in compliance with such covenants, with such
additional collateral to be accompanied by such supporting documents, financial
statements and opinions of counsel as Lender may reasonably require; provided,
however, that in order to satisfy the requirements of this SECTION 6.18(b),
Lender must also be satisfied as to the solvency of the person or entity
pledging the additional collateral. If no Default shall exist and no event or
circumstance shall have occurred or arisen which would constitute a Default but
for any unsatisfied requirement for the giving of notice or the passage of time
or both, Borrower shall have the right to obtain a release of all or any portion
of the cash collateral, the letter of credit or other collateral provided
pursuant to this SECTION 6.18 (b), as applicable, upon Lender's receipt of
financial information and/or appraisals evidencing compliance (without the
benefit of such collateral) with the covenants referred to above.

     (c) (i) Within sixty (60) days after each Accounting Period, Borrower shall
furnish to Lender detailed calculations applying the provisions of SECTION
6.18(a); and such calculations shall be certified as true and accurate, in a
manner acceptable to Lender, by a general partner of Borrower as having been
prepared under his supervision in accordance with the provisions hereof and that
he knows of no facts inconsistent with such calculations.

          (ii) Compliance with the covenants in SECTION 6.18(a) shall be tested
     as of the end of each Accounting Period.

          (iii) For the purpose of calculating Borrower's cash from operations,
     it shall be assumed that all leases of the Projects which are in Full Force
     and Effect at the time Borrower's cash from operations is being calculated
     were in Full Force and Effect at all times during the twelve month period
     then ended and that all rent concessions had expired prior to the
     commencement of such twelve month period.

          (iv) Borrower's cash from operations shall be determined without
     regard to extraordinary items of income and of expense. Each lease, the
     rental or other income from which was included in the calculations of
     Borrower's cash from operations, must be in Full Force and Effect as of the
     date Borrower's cash from operations is being calculated.

     6.19 Guaranties. Borrower will not guarantee, endorse, become surety for,
assume or otherwise in any way become or be liable for, any obligation of any
other Person, whether by agreement to purchase the indebtedness of any other
Person or agreement for the furnishing of funds through the purchase of goods,
supplies or services (or by way of stock purchase, capital contribution, advance
or loan) or for the purpose of paying the indebtedness of any other Person, or
otherwise, directly or indirectly, except for endorsements of negotiable
instruments for collection in the ordinary course of its business. Nothing in
this SECTION 6.19 shall be construed to prevent Borrower from making equity
investments in Affiliate Property Owners so long as Borrower has no continuing
obligation which would violate the prohibitions set forth in this SECTION.

     6.20 Affiliate Properties. Nothing herein shall limit Borrower's right to
acquire an Affiliate Property Owner or the right of any such Affiliate Property
Owner to acquire an Affiliate Property.

     6.21 Leasing Standards. Borrower will not enter into any lease of 10,000 or
more rentable square feet at any one or more of the Projects unless Lender has
consented, in writing, to such lease, and Lender agrees not to unreasonably
withhold or delay its consent.

               alleged violation of any Environmental Law or Environmental
               Permit and which it gives or receives with respect to any past or
               present Release or the threat of a Release on, at or from any
               Premises or any property adjacent to or within the immediate
               vicinity of any Premises, and, in any event, will immediately
               notify Lender of any such Release or threat of a Release once
               Indemnitor has knowledge of such Release or threat of a Release.

          E.   If at any time Lender obtains any evidence or information which
               suggest that potential environmental problems may exist at any
               Premises, Lender may require that a full or supplemental
               environmental inspection and audit report with respect to such
               Premises of a scope and level of detail reasonably satisfactory
               to Lender may be prepared by an environmental engineer or other
               qualified person acceptable to Lender, at Indemnitor's reasonable
               expense. Said audit may include a physical inspection of such
               Premises, a visual inspection of any property adjacent to or
               within the immediate vicinity of such Premises, personal
               interviews with Indemnitor and its agents and representatives and
               a review of all Environmental Permits. If Lender reasonably
               requires, such inspection shall also include a records search
               and/or substance testing for the presence of Hazardous Substances
               in the Environment. If said audit report indicates the presence
               of any Hazardous Substance or a Release or the material threat of
               a Release on, at or from such Premises, such Indemnitor shall
               promptly undertake and diligently pursue to completion all
               legally required investigative, containment, removal, clean up
               and other remedial actions, using methods reasonably recommended
               by the engineer or other person who prepared said audit report.
               Any action to be taken pursuant to this PARAGRAPH E shall be
               subject to the rights of tenants of the Premises. With respect to
               any access to the Premises described in this PARAGRAPH (E),
               Indemnitor shall have the right to have a representative present
               at the time of any such access or inspection or when any such
               tests are being conducted. Lender shall indemnify Indemnitor from
               and against any loss or damage to persons or property in or about
               the Premises to the extent caused by Lender or its agents or
               representative's actions pursuant to this PARAGRAPH (E).

               expenses, costs and fees (including reasonable attorneys' fees
               and disbursements) incurred in reasonably exercising any of
               Lender's rights to inspect, investigate, audit, test or review

                    failure to perform any covenant made by an Indemnitor in
                    this Agreement.

Notwithstanding anything in this Agreement to the contrary, Indemnitor's
liability in respect of the Indemnified Matters shall only arise to the extent
the Hazardous Substances, the presence of which gives rise to liability to an
Indemnitor, exist in or about the Premises during periods of Indemnitor's
ownership of the Premises. Everything in this PARAGRAPH A(1)-(7) is,
collectively, the "Indemnified Matters."

          B.   The liability of Indemnitor shall in no way be limited, abridged,

                    Documents;

               4.   Any investigation or inquiry conducted by or on the behalf

                    equitable release or discharge, in whole or in part, of
                    Indemnitor under this Agreement and as to which Indemnitor
                    may not lawfully waive the effect of such circumstance.

     V.   SURVIVAL

          A.   This Agreement shall survive repayment of the Loan, foreclosure
               of the Mortgage and a deed in lieu of foreclosure.

          B.   However, if any Indemnitee becomes a mortgagee-in- possession or
               appoints a receiver or takes title to the Premises (or any part
               thereof) through foreclosure or deed in lieu of foreclosure or
               otherwise, this Agreement shall not apply to any loss or costs
               incurred by Indemnitee as a direct result of affirmative actions
               or omissions of Indemnitee as owner or operator of such Premises
               after Indemnitee has acquired title to such Premises or becomes a
               mortgagee-in-possession thereof or appoints a receiver with

                    from the introduction and initial release of a Hazardous
                    Substance at such Premises, or

               2.   to the extent arising from Indemnitee's negligent handling
                    or disposal of Hazardous Substances lawfully at such
                    Premises for use in the normal operation and maintenance of
                    such Premises.

     C.   Otherwise, this Agreement shall remain in full force and effect,
          including, without limitation, with respect to Hazardous Substances
          which are discovered or released at the Premises (or any part thereof)
          by Indemnitee after the date Indem- nitee becomes a
          mortgagee-in-possession or appoints a receiver or acquires title to
          such Premises, but which were not actually introduced or permitted to
          be introduced at such Premises by Indemnitee, and with respect to the
          continuing migration or release of any Hazardous Substances previously
          introduced at such Premises. Notwithstanding anything in this
          Agreement to the contrary, the indemnity provided for in this
          Agreement shall not apply to the extent any

          applicable to contracts made and to be wholly performed with such

          Agreement is a Loan Document.

     XI.  LITIGATION

          A.   In the event any Indemnitee brings any action, suit or other
               proceeding in any court of record of New York State or in the
               United States District Court for the Southern District of New
               York to enforce any or all liabilities of Indemnitor hereunder,
               service of any summons, complaint, writ, judgment or other legal
               process or notice may be made upon Indemnitor by mailing a copy
               of the summons or other process to Indemnitor by certified or
               registered mail, return receipt requested, at the address set
               forth herein for nature to Indemnitor.

          B.   Indemnitor hereby irrevocably submits and consents to the
               jurisdiction of any such court over the person of Indemnitor.

          C.   Indemnitor hereby waives

               1.   TRIAL BY JURY IN ANY SUCH ACTION, SUIT OR PROCEEDING BY ANY
                    INDEMNITEE;

               2.   Any claim against any Indemnitee for punitive, consequential
                    or special damages; and

               3.   Any claim that any such court is an incon- venient forum and
                    any objection to the laying of venue in any such court.

          D.   In any action, suit or proceeding brought by any Indemnitee,
               Indemnitor agrees not to interpose any counterclaims or setoffs
               of any nature, unless the failure to assert the same would cause
               the permanent loss of such counterclaims or setoffs.

          E.   Acceptance of this Agreement by Lender shall be deemed to
               constitute a waiver by Lender of the



                                       11

               right to trial by jury in the event of any litigation in which
               Indemnitor has waived trial by jury hereunder.

          F.   Nothing herein shall (i) preclude any Indemnitee from initiating
               any such action, suit or proceeding in any other appropriate
               forum or jurisdictions, whether concurrently or not, or (ii)
               preclude any other method of effecting service of process.

     XII. COSTS

               to recover from the other party the prevailing party's reasonable
               expenses of such action (including reasonable attorneys' fees and
               disbursements).

          B.   All amounts payable under this Agreement shall be due and payable
               on demand and to the extent that any such amount shall represent
               a reimbursement for funds at any time expended by any Indemnitee
               shall bear interest, from the date of such demand, at a rate
               equal to the Peg Rate (as such term is defined in the Loan

                   FIRST AMENDMENT OF LOAN AGREEMENT AND NOTE


     FIRST AMENDMENT OF LOAN AGREEMENT AND NOTE (as the same may be amended or
otherwise modified from time to time, the "Amendment"), dated as of the day of
December, 1996, between FLEET BANK, NATIONAL ASSOCIATION, a national banking
association, having an office at 56 East 42nd Street, New York, New York 10017
("Lender"), and CORPORATE REALTY INCOME FUND I, L.P., a Delaware limited
partnership, having an office at 406 East 85th, New York, New York 10028
("Borrower").

                              W I T N E S S E T H:

     WHEREAS, pursuant to that certain Loan Agreement dated as of September 26,
1996 between Lender and Borrower (as the same may be amended or otherwise
modified from time to time, the "Loan Agreement"), Lender made a loan to
Borrower in the original principal amount of up to Twenty-Four Million and
00/100 ($24,000,000.00) Dollars (the "Loan");

     WHEREAS, the Loan is evidenced by that certain promissory note of even date
with the Loan Agreement (as the same may be amended or otherwise modified from
time to time, the "Note") made by Borrower payable to the order of Lender;

     WHEREAS, the Loan is secured by, among other things, the Mortgages; and

     WHEREAS, Lender and Borrower desire to modify and amend the terms and
provisions of the Loan Agreement and the Note as hereinafter provided.

     NOW, THEREFORE, in consideration of the covenants set forth herein and for
other good and valuable consideration, the receipt and legal sufficiency of
which is hereby acknowledged, Lender and Borrower hereby agree as follows:

1.   Definitions. All capitalized terms used herein without definition and which
     are defined in the Loan Agreement are used herein with the meanings
     assigned to such terms in the Loan Agreement.

2.   Amendments to Loan Agreement. The Loan Agreement is hereby modified as
     follows:

     a.   SECTION 1.01 is hereby modified to delete the reference to a principal
          sum of "TWENTY-FOUR


<PAGE>



          MILLION AND NO/1OOTHS DOLLARS ($24,000,000)" and, to substitute in
          lieu thereof, a reference to a principal sum of "FORTY-FOUR MILLION
          AND NO/100THS DOLLARS ($44,000,000)".

     b.   With respect to SECTION 2.03, Lender understands that Borrower has
          assumed the defense in the action entitled Lister - Butler, Inc. v.
          Metropolitan Life Insurance Company and currently pending in the New
          York Supreme Court, New York County.

     c.   SECTION 6.04 is hereby amended to delete the reference to a principal
          sum of "Twenty-Four Million Dollars ($24,000,000)" and, to substitute
          in lieu thereof, a reference to a principal sum of "Forty-Four Million
          Dollars ($44,000,000)".

     d.   SECTION 6.06 is hereby amended to add the following thereto as a new
          SECTION 6.06(e):

               "(e) Borrower has executed and delivered to Lender a Mortgage
          encumbering the Project commonly known as 475 Fifth Avenue, New York,
          New York (the "New York Project"). The principal amount of the Loan
          allocated to the New York Project is $18,370,000 (the "New York
          Advance") and, to account for the difference between the allocated
          Loan amount and the release price, the principal amount of the Loan to
          be secured by the New York Project shall initially be $20,207,000
          (such portion of the Loan, the "New York Tranche"). Notwithstanding
          anything in the Loan Documents to the contrary, neither the New York
          Advance nor the New York Tranche shall be a revolving loan, and any
          repayments of the New York Advance or the New York Tranche may not be
          reborrowed, but this provision shall not limit Borrower's right to
          receive an Advance to the extent that Advances are otherwise
          available.

     e.   SECTION 6.07 is hereby restated to read, in its entirety, as follows:

          "Concurrently with each monthly payment of interest under the Loan,
          Borrower shall make monthly principal payments to Lender in an amount
          equal to the sum of the following: the initial principal amount of
          each advance of the Loan divided by 500, with such calculation to be
          made separately for each advance and the monthly payment shall be sum
          of such separate calculations. In the event of any repayments of



                                        2

<PAGE>

          the Loan (other than as a result of the required monthly
          amortization), Lender shall allocate such repayment to one or more of
          the Loan advances and recalculate the required monthly principal
          amortization with respect to such advance and the aggregate required
          monthly amortization payment, but Lender shall not allocate such
          repayment to the New York Advance unless (i) the only portion of the
          Loan outstanding is the New York Advance or (ii) Borrower, in writing,
          directs Lender to apply such repayment to the New York Advance.
          Notwithstanding the provisions of this Agreement allowing Borrower to
          reborrow amounts previously repaid, any monthly principal payments
          pursuant to this SECTION 6.07 shall reduce the Loan commitment by a
          like amount and may not be reborrowed."

     f.   SECTION 6.08 is hereby amended to delete the reference to "one-quarter
          percent (1/4%)" and to substitute, in lieu thereof, a reference to
          "one-half of one percent (1/2%)".

     g.   SECTION 6.09 is hereby amended to delete the language commencing with
          "(3) the negotiation" and ending with "counsel to Lender" and to
          substitute, in lieu thereof, the following: " (3)(i) the negotiation,
          preparation and/or execution of any amendment, waiver, supplement or
          modification to any of the Loan Documents and any other documents and
          instruments prepared in connection therewith and the consummation of
          the transactions contemplated thereby, and (ii) the negotiation,
          preparation and/or execution (x) of any participation, intercreditor,
          agency and other agreements whereby Lender sells an interest in the
          Loans and the execution and delivery of all instruments and documents
          related thereto and (y) of any amendments, waivers, supplements or
          modifications thereto, including, in the event of costs or expenses
          referred to in the preceding clauses (1), (2) and/or (3), the
          reasonable fees and disbursements of counsel to Lender."

     h.   EXHIBIT C (which is referred to in SECTION 6.10(c) of the Loan
          Agreement), is hereby amended to provide for new Loan allocations for
          the Projects. Such revised Loan allocations are as follows:




                                        3

                  REVISED LOAN ALLOCATIONS FOR PROJECTS

          (i)  21.15 acre site located in the Ventura Industrial Park in the

               -- $6,454,800.

          (vii) 475 Fifth Avenue, New York, New York -- $18,370,000.

     i.   For the purposes of testing compliance with the provisions of SECTION
          6.18(a)(A)(ii) and SECTION 6.18(a)(C), the value attributable to the
          New York Project shall be the lesser of (i) the Appraised Value of the
          New York Project (as it may change from time to time in accordance
          with the provisions of the Loan Agreement); and (ii) 182% of the
          outstanding principal amount of the New York Advance.

     j.   SECTION 6.18(a) of the Loan Agreement is hereby amended to delete the
          reference to "two hundred and ten percent" and to substitute in lieu
          thereof a reference to "one hundred and eighty two percent" in SECTION
          6.18(a)(A)(ii) and to delete the reference to "$1,000,000" and to
          substitute in lieu thereof a reference to "$2,000,000" in SECTION
          6.18(a)(B).

     k.   SECTION 6.21 is hereby amended to add the following at the end
          thereof:

               "Provided, however, that with respect to the New York Project,
          such 10,000 rentable square foot number shall be 5,000 rentable square
          feet. Any lease which Borrower is to enter into must be on
          commercially reasonable terms and conditions.



                                        4

<PAGE>



     l.   With respect to the definition of "Debt Service Coverage Ratio" in
          SECTION 7.01 of the Loan Agreement (i) such definition is hereby
          modified to delete the reference to "1.75%" and to substitute, in lieu
          thereof, a reference to "1.50%" and (ii) in calculating Borrower's
          cash from operations, fees paid by Borrower to its general partners
          shall not be treated as expenses.

     3.   Amendments to Note. The Note is hereby modified as follows:

          a.   The reference on the first page of the Note to a "Principal
               Amount" of $24,000,000 is hereby amended to be a reference to a
               "Principal Amount" of $44,000,000.

          b.   Effective as of September 26, 1996, all references in the Note to
               two and one-quarter percent (2.25%) shall be deemed to be
               references to two percent (2.0%). Lender will allow Borrower an
               appropriate credit in its next interest payment to adjust for
               this retroactive reduction in the interest rate.

     4.   Confirmation Regarding Environmental Compliance and Indemnification
          Agreement. Borrower hereby confirms and agrees that, from and after
          the date hereof, the New York Project is and shall be considered part
          of the Premises (as such term is defined in the Environmental
          Compliance and Indemnification Agreement).

     5.   Outstanding Loans. Borrower represents and warrants to Lender that
          there are no offsets, defenses or counterclaims to its obligations
          under the Loan Documents and to the extent that any such offsets,
          defenses or counterclaims exist without its knowledge, the same are
          hereby waived to the fullest extent permitted by law. Except as
          modified by this Amendment and by amendments to the other Loan
          Documents being executed and delivered concurrently herewith, the
          terms and provisions of the Loan Documents are hereby ratified and
          confirmed in all respects and continue in full force and effect.

     6.   Modifications. No provision of this Amendment may be waived, amended
          or supplemented except by a written instrument executed by Borrower
          and Lender.

     7.   Successors and Assigns. This Amendment, which sets forth the entire
          understanding of the parties hereto



                                        5

<PAGE>



          with respect to the subject matter hereof, inures to the benefit of,
          and shall be binding upon, the parties hereto and their respective
          successors and assigns.

     8.   Severability. In the event that any one or more of the provisions
          contained in this Amendment shall for any reason be held to be
          invalid, illegal or unenforceable in any respect, such invalidity,
          illegality or unenforceability shall not affect any other provision of
          this Amendment, but this Amendment shall be construed as if such
          invalid, illegal or unenforceable provision had never been contained
          herein.

     9.   Captions. Captions used in this Amendment are for convenience of
          reference only and shall not be deemed a part of this Amendment nor
          used in the construction of its meaning.


     IN WITNESS WHEREOF, Borrower and Lender have duly executed this Amendment,

     2.2. Warranty of Title. The Trustor warrants that, to the best of the
Trustor's knowledge (a) the Mortgaged Premises are free and clear of all liens
and encumbrances other than the Permitted Encumbrances; (b) it owns the Building

Beneficiary, as follows:

          (i) that the Trustor is lawfully seized and possessed of a fee in the
     Premises and that the Trustor holds good legal and marketable title thereto
     and to the rest of the Mortgaged Premises, subject only to the Permitted
     Encumbrances; and

          (ii) that the Mortgaged Premises are now free and clear of all liens
     and encumbrances whatsoever, other than the Permitted Encumbrances, that
     the Trustor has good right and lawful authority to mortgage and convey the

     warrant and defend title to the Mortgaged Premises against all claims and
     demands whatsoever.

     2.3. To Maintain Priority of Lien.

     2.3.1. This Trust Deed is and will be maintained as a valid first lien deed
of trust on the Mortgaged Premises, and the Trustor will not, directly or

Mortgaged Premises or any portion thereof, or against the rents, issues and
profits therefrom, and will promptly discharge, any lien or charge prior to or
upon a parity with or junior to the lien of this Trust Deed other than the

promptly shall discharge the lien of record, by bonding or otherwise. The
Trustor shall exhibit to the Beneficiary, upon request, appropriate receipts or
other satisfactory evidence of the payment of the Impositions or any other item
which may, if not paid, give rise to a lien against the Mortgaged Premises.

     2.4. To Pay Impositions.

     2.4.1. The Trustor will pay or cause to be paid, as and when due and
payable, all Impositions levied upon the Mortgaged Premises or any part thereof.
However, if by law, any Imposition may at the option of the taxpayer be paid in
installments (whether or not interest shall accrue on the unpaid balance
thereof), the Trustor shall have the right to exercise such option and to pay
such Imposition, or cause it to be paid (together with any accrued interest on
the unpaid balance) in installments as they fall due and before any fine,
penalty, further interest or cost may be added thereto.

     2.4.2. If an Event of Default shall occur and be continuing, then upon
demand of the Beneficiary, the Trustor shall deposit with the Beneficiary a sum
which bears the same relation to the annual insurance premiums for all insurance
required by the terms hereof and real estate taxes and assessments assessed
against the Mortgaged Premises for the insurance period or tax year then in
effect, as the case may be, as the number of months elapsed as of the date of
such demand since the last preceding installment of said premiums or taxes or
assessments shall have become due and payable bears to twelve (12). For the
purpose of this computation, the month in which such last preceding installment
of premiums or real estate taxes or assessments became due and payable and the
month in which such demand is given shall be included and deemed to have
elapsed. On the first day of the month next succeeding the month in which such
demand is given, and thereafter on the first day of each and every month during
the term of this Trust Deed, the Trustor shall deposit with the Beneficiary a
sum equal to one-twelfth of such insurance premiums and such taxes and
assessments for the then-current insurance period and tax year, so that as each
installment of such premiums and taxes and assessments shall become due and
payable, the Trustor shall have deposited with the Beneficiary a sum sufficient
to pay the same. All such deposits shall be received and held as part of such
deposit by the Beneficiary (all such deposits to be held in an account without
interest thereon) and shall be applied to the payment of each installment of
such premiums and taxes and assessments as they shall become

                                     - 10 -

due and payable. The Beneficiary shall, upon demand, furnish evidence to the
Trustor of the making of each such payment. If the amount of such premiums and
taxes and assessments has not been definitely ascertained at the time when any
such monthly deposits are required to be made, the Trustor shall make such
deposits based upon the amount of such premiums and taxes and assessments for
the preceding year, subject to adjustment as and when the amount of such
premiums and taxes and assessments are ascertained. If at any time when any
installment of such premiums and such taxes and assessments becomes due and
payable the Trustor shall not have deposited a sum sufficient to pay the same,
the Trustor shall, within five (5) days after demand, deposit any deficiency
with the Beneficiary. Upon payment in full of the indebtedness secured by this
Trust Deed, any remaining amount on deposit with the Beneficiary shall be repaid
to the Person lawfully entitled thereto. If an Event of Default shall occur and
be continuing, the Beneficiary may, at its option, apply all or any portion of
the amounts then on deposit with the Beneficiary pursuant to this SECTION 2.4.2
first to the payment of any premiums, taxes or assessments then due, and any
remaining amounts may be applied to the payment of the indebtedness. The Trustor
shall deliver to the Beneficiary all insurance and tax bills promptly following
receipt during any period when such monthly deposits are to be made with the
Beneficiary.

     2.4.3. The Trustor will pay all taxes and other governmental charges
(including, without limitation, stamp taxes), except income or franchise taxes
or similar taxes based upon or measured by income, assessed by the United States
government or any state or local governmental authority and imposed on the
Beneficiary, its successors by reason of the ownership of this Trust Deed or the
Note or the receipt of the interest or other sums payable thereunder or payable
by either the Trustor or the Beneficiary upon any increase in the indebtedness
secured hereby, or any modification, amendment, extension or consolidation of
this Trust Deed. Without limiting the foregoing and subject to the limitations
set forth above, the Trustor will also pay the whole of any tax imposed,
directly or indirectly, on this Trust Deed or the Note or the receipt of any
portion of the Indebtedness in lieu of a tax on the Mortgaged Premises or the
Improvements and Building Service Equipment, whether by reason of (a) the
passage after the date of this Trust Deed of any law of the State deducting from
the value of real property for the purposes of taxation any lien thereon; (b)
any change in the laws for the taxation of Trust Deeds or debts secured by trust
deeds for state or local purposes; (c) a change in the means of collection of
any such tax or

                                     - 11 -

otherwise; or (d) any tax, whether or not now existing, assessed against, or
withheld from, interest or other payments made by the Trustor or assessed
against this Trust Deed and which are assessed or levied by the government of
any foreign nation or political subdivision thereof, provided such tax liability
shall not result from the ownership of this Trust Deed by a Person not a citizen
of, or an entity not formed under the laws of, the United States or any state.
Within a reasonable time after payment of any such tax or governmental charge,
the Trustor will deliver to the Beneficiary satisfactory proof of payment
thereof, subject, however, to the right of the Trustor to contest Impositions as
hereinafter set forth. If the Trustor shall fail to pay such tax or charge
within fifteen (15) days after written notice, or if under applicable law the
Trustor's payment or agreement to pay the same shall be unenforceable, the
Beneficiary shall have the right to declare the entire unpaid indebtedness and
all accrued and unpaid interest thereon due and payable on a date specified by
the Beneficiary, but, in any event, not less than thirty (30) days after written
notice to the Trustor.

     2.4.4. The Trustor shall have the right to contest the amount or validity,
in whole or in part, of any Imposition, or to seek a reduction in the valuation
of the Mortgaged Premises, or any part thereof, as assessed for real estate or
personal property tax purposes by appropriate proceedings diligently conducted
in good faith, but only after payment of such Imposition, unless such payment
would operate as a bar to such contest or materially adversely interfere with
the prosecution thereof, in which event the Trustor may postpone or defer
payment of such Imposition (but not the payment of any monthly deposits pursuant
to SECTION 2.4.2 hereof); and upon request by the Trustor, the Beneficiary shall
postpone or defer payment of such Imposition; provided, however, that if at any
time the Mortgaged Premises, the Building Service Equipment, the Furnishings, or
any part thereof would, in the Beneficiary's reasonable judgment, by reason of
such postponement or deferment be in imminent danger of being forfeited or lost,
or if the Beneficiary might be subjected to any civil or criminal liability or
other sanction, then the Trustor, on demand, shall immediately pay or cause to
be paid the amount so contested and unpaid, together with all interest and
penalties in connection therewith.

     2.4.5. The certificate, advice or bill of the appropriate official
designated by law to make or issue the same or to receive payment of any
Imposition indicating the nonpayment of such Imposition shall be prima facie

                                     - 12 -

evidence that such Imposition is due and payable but unpaid at the time of the
making or issuance thereof.

     2.5. Insurance; Restoration Following Casualty.

     2.5.1. Until the indebtedness secured hereby is paid in full, the Trustor
shall at its own expense at all times maintain or cause to be maintained on all
of the Mortgaged Premises (a) comprehensive general liability insurance,
including umbrella liability insurance, covering all claims for bodily injury,
including death, and property damage occurring on, in or about the Mortgaged
Premises in an aggregate amount of not less than Five Million Dollars
($5,000,000) per occurrence, and a single limit of not less than Two Million
Dollars ($2,000,000) per person and per occurrence for personal injury, bodily
injury and property damage; the policy shall have no deductible or self insured
retention requirements; the policy limits of such insurance, if requested by the
Beneficiary, shall be increased from time to time to reflect what a reasonably
prudent owner or lessee of buildings or improvements similar in type and
locality to the Mortgaged Premises would carry; during any period of substantial
alterations or improvements in, on or to the Mortgaged Premises, the Trustor
will cause the comprehensive general liability insurance, including umbrella
liability insurance, endorsed to provide owners' and contractors' protective
liability coverage, including completed operations liability coverage; (b)
physical damage insurance (all risk non-reporting property insurance, including
earthquake insurance, with the Beneficiary named as loss payee), covering the
Mortgaged Premises for loss or damages resulting from the perils of fire,
lightning, earthquake, and such other risks and hazards as are provided under
the current standard "Extended Coverage Endorsement" and vandalism and malicious
mischief coverage, for the full replacement value of the Mortgaged Premises on a
stipulated and agreed-amount basis; (c) if the Mortgaged Premises is in an area
identified as a flood hazard area by the Secretary of Housing and Urban
Development, flood insurance, to the extent obtainable, in an amount equal to
the lesser of the full replacement value of the Mortgaged Premises or the
maximum amount available under the Federal flood insurance program; (d) boiler
and machinery insurance covering all boilers, machinery, air conditioning,
pressure vessels, and similar type equipment commonly covered under a broad-form
boiler and machinery policy, in an amount satisfactory to the Beneficiary; (e)
insurance against such other risks of damage, hazards, casualties and
contingencies in such amounts as the Beneficiary shall from time to time
reasonably require, provided that insurance against such

                                     - 13 -

other risks, hazards, casualties or contingencies shall then be commonly carried
by prudent owners or lessees of building or improvements in the locality similar
in character, construction, use and occupancy to the Improvements, Building
Service Equipment and Furnishings on, or constituting a part of, the Mortgaged
Premises; and (f) loss of rents/business interruption coverage in an amount
sufficient to pay all Impositions, insurance premiums, interest and principal
installments and all other amounts due under the Note and the Loan Agreement and
the normal operating expenses of the Mortgaged Premises, all for a period of one
(1) year. Furthermore, the Beneficiary reserves the right to require additional
insurance and/or higher policy limits than heretofore specified if such
additional insurance and/or higher policy limits are commercially reasonable for
similar properties, which right may be exercised by written notice to the
Trustor, and, as soon thereafter as practicable, but in any event within thirty
(30) days of the receipt thereof, the Trustor agrees to obtain insurance
coverage complying with such notice. The proceeds of all such insurance (except
the insurance specified in SECTION 2.5.1(a)) shall be paid solely to the
Beneficiary and be held, applied or disbursed by the Beneficiary as provided in
SECTIONS 2.5.7 and 2.5.8.

     2.5.2. All insurance required in SECTION 2.5.1 shall be evidenced by valid
and enforceable policies, in form and substance as shall be required by the
Beneficiary from time to time, and issued by and distributed among insurers of
recognized responsibility having an A.M. Best's Guide of A:XII or better, a
financial size category of Class XI or above, and the total limit of liability
shall not exceed ten percent (10%) of the total policyholders' surplus. Such
insurers shall be authorized to do business in the State and in all other
respects shall be reasonably satisfactory to the Beneficiary. The originals of
all such policies, or duplicate copies or certificates thereof, shall be
delivered to the Beneficiary concurrently with the execution and delivery of
this Trust Deed. Thereafter, all renewal or replacement policies, or duplicate
copies or certificates thereof, shall be delivered to the Beneficiary not less
than thirty (30) days prior to the expiration date of the policy or policies to
be renewed or replaced, in each case accompanied by evidence reasonably
satisfactory to the Beneficiary that all premiums currently payable with respect
to such policies have been paid in full by or at the direction of the Trustor.

     2.5.3. All such insurance policies shall (a) except for any liability
policy required hereunder,

                                     - 14 -

contain a standard noncontributory form of mortgagee clause (in favor of and
entitling the Beneficiary to collect any and all proceeds payable under such
insurance), as well as a standard waiver of subrogation endorsement, all to be
in form and substance reasonably satisfactory to the Beneficiary; (b) provide
that such policies may not be cancelled or amended without at least thirty (30)
days prior written notice to the Beneficiary; and (c) provide that no act,
omission or negligence of the Trustor, or its agents, servants or employees, or
of any Space Tenant under any Space Lease, which might otherwise result in a
forfeiture of such insurance or any part thereof, shall in any way affect the
validity or enforceability of such insurance insofar as the Beneficiary is
concerned. The Trustor shall not carry separate insurance, concurrent in kind or
form or contributing in the event of loss with any insurance required under this
SECTION 2.5. All losses under such insurance policies shall be adjusted by the
Trustor in the case of any single instance of such damage or destruction not
exceeding $200,000, by the Trustor and the Beneficiary in the case of any such
single instance of damage or destruction exceeding such amount, provided that in
no event shall the Trustor approve or consent to any final adjustment in any
amount exceeding the amount specified above in this sentence without obtaining
the Beneficiary's prior approval (which approval shall not be unreasonably
withheld) of the amount of such adjustment, and solely by the Beneficiary in the
case when an Event of Default exists and is continuing.

     2.5.4. The Trustor, at its expense, will furnish to the Beneficiary, within
ninety (90) days after written demand, but in no event, except for reasonable
cause, more frequently than annually, proof of the then full replacement value
of each of the Improvements and the Building Service Equipment and Furnishings
therein, such proof to be by appraisals reasonably satisfactory in form and
substance to the Beneficiary and prepared by an appraiser (who may be an
appraiser for the insurance company insuring such property) designated and paid
for by the Trustor and approved by the Beneficiary, which approval shall not be
unreasonably withheld or delayed.

     2.5.5. If the Beneficiary shall, by any means, acquire the title or estate
of the Trustor in or to any portion of the Mortgaged Premises, it shall
thereupon become the sole and absolute owner of all insurance policies affecting
such portion of the Mortgaged Premises held by, or required hereunder to be
delivered to, the Beneficiary, with the sole right to collect and retain all
unearned premiums thereon; and the Trustor shall be entitled only to a credit

in reduction of the then outstanding indebtedness secured hereby in the amount
of the short rate cancellation refund, when and if received by Beneficiary. The
Trustor agrees, immediately upon demand, to execute and deliver such assignments
or other authorizations or instruments as may, in the reasonable opinion of the
Beneficiary, be reasonably necessary or desirable to effectuate any of the
provisions of this SECTION 2.5.5.

     2.5.6. If any of the Improvements, Building Service Equipment or
Furnishings shall be damaged or destroyed, in whole or in part, by fire or other
casualty, the Trustor shall give prompt notice thereof to the Beneficiary, and,
without regard to the availability or adequacy of insurance proceeds, shall
promptly following receipt of any insurance proceeds or the date when any such
proceeds are made available to the Trustor in accordance with the terms hereof,
commence to restore, replace, rebuild or alter the same as nearly as possible to
the condition, character and value thereof existing immediately prior to such
damage or destruction. Any insurance proceeds in respect of such damage or
destruction, or any Award (as defined in SECTION 3.2) for a partial taking which
is not a substantial or total taking, as such terms are referred to in ARTICLE
III hereof, at the option of the Beneficiary, may either (i) be applied as a
prepayment of the unpaid balance of the principal of the Note and of accrued and
unpaid interest thereon and as a payment of any other sums due and owing under
the Note, the Loan Agreement and the Security Documents, or (ii) be made
available to pay or reimburse costs incurred for restoration, replacement or
rebuilding necessitated as a result of such damage or destruction, or as a
result of such taking, as the case may be, or (iii) be used for any other
purpose or object deemed appropriate by the Beneficiary in connection with the
Mortgaged Premises, provided, however, that the Beneficiary may not elect either
option (i) or (iii) above if, and for so long as all of the following conditions
(collectively, the "Insurance or Award Conditions" have been and remain
satisfied: (a) no Event of Default has occurred and is continuing or would occur
as a result of such casualty or taking and no event has occurred that with the
passage of time or the giving of notice, or both, would constitute an Event of
Default; (b) the balance of the insurance proceeds or such Award either
initially paid to the Beneficiary or deposited with the Depository (as
hereinafter defined) or remaining from time to time, shall be sufficient, in the
Beneficiary's reasonable judgment, to complete the restoration, replacement or
rebuilding, or the Trustor shall have deposited such sufficient funds with the
Beneficiary or the Depository; and (c) the Beneficiary

                                     - 16 -

determines, in its reasonable discretion, that (i) the Loan to Value Ratio (as
defined in the Loan Agreement, and taking into consideration the value of all of
the Projects, as defined in the Loan Agreement) is not greater than 55%, and
(ii) the Debt Service Coverage Ratio (as defined in the Loan Agreement, and
taking into consideration the loss of income resulting from such damage or
destruction as projected by the Beneficiary in its reasonable discretion) is not
less than 1.40:1.0. Notwithstanding the foregoing, if an event has occurred and
is continuing that with the passage of time or the giving of notice, or both,
would constitute an Event of Default but the same has not yet matured into an
Event of Default, then, if the conditions set forth in the foregoing clauses (b)
and (c) have been or will be, in the Beneficiary's reasonable judgment,
satisfied, the Beneficiary shall not elect either option (i) or (iii) unless
such event shall have matured into an Event of Default and, unless and until
such event shall have so matured into an Event of Default or such event has been
cured or shall otherwise cease to exist, the Beneficiary (or the Depository)
shall not release any such insurance proceeds or Award and the same shall be
held until an Event of Default occurs or the Default has been cured or shall
otherwise cease to exist.

     2.5.7. Any such insurance proceeds (other than the proceeds of the rent
insurance policy, which shall be paid as provided in SECTION 2.5.8 below) or
Award which are to be applied to restoration, replacement or rebuilding of the
Mortgaged Premises shall, after payment or reimbursement to the Beneficiary of
all reasonable costs and expenses of the Beneficiary in collecting such proceeds
or Award, be applied upon satisfaction of the following provisions and
conditions:

          (a) If the damage be of such nature as to require the Trustor to
     construct a replacement for, or to alter in any material or substantial
     way, the damaged or destroyed items, the Trustor shall, before commencing
     any such work, submit copies of the plans and specifications therefor to
     the Beneficiary for the Beneficiary's approval, such approval to not be
     unreasonably withheld or delayed.

          (b) If after payment or reimbursement to the Beneficiary of all costs
     and expenses of the Beneficiary in collecting such insurance proceeds or
     Award, the aggregate insurance proceeds or Award received by reason of any
     single instance of such damage or destruction or condemnation, as the case
     may

     be, shall be $200,000 or less such insurance proceeds or Award shall be
     paid to the Trustor, which shall hold all amounts so received in trust for
     application first to pay the entire cost of restoring, repairing,
     rebuilding or replacing the damaged or destroyed items, before any portion
     of such proceeds may be used or applied for any other purpose. If the
     aggregate net insurance proceeds or Award by reason of any single instance
     of such damage or destruction or condemnation, as the case may be, shall be
     more than $200,000 such sums shall be held and disbursed by Fleet Bank,
     National Association or, if this Trust Deed is held by another financial
     institution, by such financial institution or, if this Trust Deed is not
     held by a financial institution, by a financial institution selected by the
     then Beneficiary (the holder of such monies, the "Depository") in
     accordance with the following provisions of this SECTION 2.5.7.

          (c) The Beneficiary shall have received as to each such disbursement a
     certificate of the Trustor (i) requesting the payment of a specified amount
     of such insurance or condemnation proceeds; (ii) describing in reasonable
     detail the work and materials applied to the restoration, replacement or
     rebuilding of the damaged, destroyed or taken Improvement, or Building
     Service Equipment and/or Furnishings located therein, since the date of the
     last such certificate; (iii) stating that the requested amount does not
     exceed the cost of such work and materials; and (iv) stating that a request
     for payment for such work and materials has not previously been made,
     accompanied by:

               1. a certificate of an independent engineer or architect
          designated by the Trustor, who shall have been approved in writing by
          the Beneficiary (such approval not to be unreasonably withheld),
          stating (i) that the work and materials described in the accompanying
          certificate of the Trustor were satisfactorily performed and furnished
          and were necessary, appropriate or desirable to the restoration,
          replacement or rebuilding of the damaged, destroyed or taken
          Improvement, or Building Service Equipment and/or Furnishings; (ii)
          that the amount specified in such certificate of the Trustor does not
          exceed the reasonable cost of such work and materials; and (iii) the

                                     - 18 -

          additional amount, if any, required to complete the restoration,
          replacement or rebuilding of the damaged, destroyed or taken
          Improvement, Building Service Equipment and/or Furnishings; and

               2. evidence reasonably satisfactory to the Beneficiary (i) that
          there exists no filed or recorded lien, or lien notice, or encumbrance
          or charge in respect of all or any part of the Mortgaged Premises that
          is prior to or on a parity with the lien of this Trust Deed, except as
          may be permitted in the Permitted Encumbrances; (ii) that neither the
          Mortgaged Premises nor any part thereof is subject to any recorded or
          filed mechanic's, laborer's, materialman's or any similar lien,
          encumbrance or charge; and (iii) that none of the Building Service
          Equipment and Furnishings provided in connection with such
          restoration, replacement or rebuilding is subject to any security
          interest other than in favor of the Beneficiary;

     Upon satisfaction of the conditions set forth herein, the Beneficiary shall
pay to the Trustor the amount of such insurance or condemnation proceeds
requested in such certificate of the Trustor or consent to the Depository's
payment thereof, as the case may be; provided, however, that in no event shall
the balance of insurance or condemnation proceeds held by the Beneficiary and
the Depository be reduced below the amount specified in such certificate of the
independent engineer or architect as the amount required to complete the
restoration, replacement or rebuilding of the damaged, destroyed or taken
Improvement, Building Service Equipment and/or Furnishings. Each such payment,
whether made by the Beneficiary or the Depository, shall be held by the Trustor
in trust and shall be used solely for the payment of the cost of the work and
materials described in the certificate of the Trustor, or if such cost or any
part thereof has theretofore been paid by the Trustor out of its own funds, then
for the reimbursement to the Trustor of any such cost or part thereof paid by
it. Any balance of insurance or condemnation proceeds held by the Beneficiary
after the completion of the restoration, replacement or rebuilding and payment
of all costs incurred in connection therewith, to be evidenced by a certificate
to such effect of such independent engineer or architect delivered to the
Beneficiary, shall, if no Event of Default shall have occurred and be
continuing, be released to the Person lawfully entitled thereto. Notwithstanding
the foregoing,

                                     - 19 -

if the Trustor needs to make deposits with or payments to contractors prior to
the work being performed, if the Beneficiary is otherwise obligated to allow
funds to be used to rebuild or restore, the Beneficiary agrees that it will not
unreasonably withhold or delay its consent to the Trustor's request that such
deposits or advances payments be allowed.

     2.5.8. All proceeds of rent insurance payable as a result of the occurrence
of any fire or other casualty which affects the Mortgaged Premises, or any part
thereof, shall be paid to the Beneficiary or, if the Beneficiary is not a
financial institution, the Depository. The Beneficiary or the Depository, as the
case may be, if it shall receive such proceeds, shall hold such proceeds in
trust if permitted under law, and in an account bearing interest (payable to or
for account of the Trustor), and shall apply or cause such proceeds (including
any net interest thereon) to be applied to the payment of those items referred
to in SECTION 2.5.1(f) which become, and as they become, due and payable from
and after the date of the occurrence of such damage or loss, until the
completion of the necessary restoration or replacement by the Trustor or until
the exhaustion of such proceeds (including any interest thereon), whichever
first occurs. Upon completion of such restoration or replacement, any balance of
such rent insurance proceeds, together with the interest thereon, if any, not
theretofore applied as provided herein, in the hands of the Beneficiary or the
Depository, as the case may be, shall, provided that no Event of Default shall
have occurred and be continuing, be paid to the Person lawfully entitled
thereto.

     2.5.9. Nothing in this SECTION 2.5 contained shall (i) relieve the Trustor
of its duty to repair, restore, rebuild or replace the Improvements, Building
Service Equipment and/or Furnishings following damage or destruction by fire or
other casualty or taking in the event that no Award or an inadequate Award or
that no or inadequate proceeds of insurance are available to defray the cost of
such repairing, restoring, rebuilding or replacement (provided, however, the
Trustor shall be permitted to receive the insurance proceeds upon satisfaction
of the conditions set forth herein provided, in addition, that all of the
Insurance or Award Conditions have been and remain satisfied), or (ii) relieve
the Trustor of its obligation to pay principal and interest and to make all
other payments required by the Note, the Loan Agreement and this Trust Deed
subsequent to the occurrence of any fire or other casualty, or taking, except
if, and to the extent that, any proceeds

of rent insurance are applied by the Beneficiary in accordance with SECTION
2.5.8 to such required payments.

     2.5.10. If, while any insurance proceeds or Award is being held by the
Beneficiary or the Depository, an Event of Default shall occur and be
continuing, the Beneficiary shall be entitled to receive and apply all such
insurance proceeds or Award in reduction of the indebtedness and other
obligations secured by this Trust Deed, in such order and respective amounts, as
the Beneficiary in its discretion shall determine.

     2.6. To Comply with Laws.

     2.6.1. The Trustor, at its own expense, will promptly cure all violations
of law affecting the Mortgaged Premises, or any part thereof, and/or the use and
operation thereof and will promptly comply, or cause to be complied with, all
present and future Legal Requirements. However, the Trustor shall have the
right, after prior notice to the Beneficiary, to contest by appropriate legal
proceedings, diligently conducted in good faith, the validity or application of
any Legal Requirement if and so long as the Trustor shall promptly furnish to
the Beneficiary a certificate to such effect showing the steps taken to comply
with such provisions, provided that:

          (a) if by the terms of any such Legal Requirement, compliance
     therewith pending the prosecution of any such proceeding may be delayed
     legally without incurring any lien, charge or liability of any kind against
     the Mortgaged Premises, or any part thereof, and without subjecting the
     Trustor or the Beneficiary to any liability, civil or criminal, for failure
     so to comply therewith, the Trustor may delay compliance therewith until
     the final determination of any such proceeding; and

          (b) if any lien, charge or civil liability would be incurred by reason
     of any such delay, the Trustor nevertheless, on the prior written consent
     of the Beneficiary, such consent not to be unreasonably withheld, may
     contest and delay compliance with the Legal Requirement, provided that such
     delay would not subject the Beneficiary to criminal liability and the
     Trustor (i) furnishes to the Beneficiary security reasonably satisfactory
     to the Beneficiary against loss or injury by reason of such contest or
     delay and (ii) prosecutes the contest with due diligence.

     2.6.2. Notwithstanding the provisions of SECTION 2.6.1, if any delay in
compliance with any Legal Requirement shall, in the reasonable judgment of the
Beneficiary, place all or any part of the Mortgaged Premises in imminent danger
of being forfeited or lost, the Trustor shall, upon written notice from the
Beneficiary, immediately comply with such Legal Requirement.

     2.6.3. The Trustor will use and permit the use of the Mortgaged Premises
only in accordance with the material requirements of any applicable licenses and
permits issued by Governmental Authorities.

     2.6.4. The Trustor will procure, pay for and maintain (or cause to be
procured, paid and maintained) all permits, licenses and other authorizations
required to be procured and maintained by the owners and operators of the
Mortgaged Premises for any then use of all or any part of the Mortgaged Premises
then being made and for the lawful and proper operation and maintenance thereof.

     2.7. Limitation on Alterations and Demolition.

     2.7.1. The Trustor shall not voluntarily demolish, replace or alter the
Mortgaged Premises, or any part thereof, or voluntarily make any addition
thereto, or voluntarily construct any additional improvements thereon, or suffer
any of the same to occur, whether structural or otherwise (collectively,
"change"), without the prior written consent of the Beneficiary, which consent
shall not be unreasonably withheld or delayed; provided, however, that if no
Event of Default is continuing and such change involves an estimated cost of
less than $100,000 and is non-structural or if no Event of Default is continuing
and such change is non-structural and is being made to prepare space for a Space
Tenant pursuant to a Space Lease entered into in accordance with the Loan
Agreement, then, in either of such events, the Beneficiary's consent shall not
be required; provided, further, however, that if any such change is required by
law, the Trustor may make such change with the prior written consent of the
Beneficiary, which consent the Beneficiary will not unreasonably withhold or
delay. As a condition to any consent under this SECTION 2.7.1, the Beneficiary
may require (a) that plans and specifications for the proposed work, prepared by
a reputable architect reasonably satisfactory to the Beneficiary, be submitted
to the Beneficiary for approval, and (b) that the Trustor obtain a payment and
performance bond or other security reasonably satisfactory to the Beneficiary in
form and amount reasonably satisfactory to the Beneficiary from the

                                     - 22 -

contractor or subcontractor performing the work unless such work amounts to less
than $200,000 in aggregate total cost. All work performed by or on behalf of the
Trustor shall be completed with all reasonable diligence and continuity, in a
good and workmanlike manner, and in compliance with all applicable Legal
Requirements. Unless, and to the extent that, the provisions of SECTION 2.7.2 be
applicable, no Building Service Equipment or Furnishings shall be removed from
the Mortgaged Premises during the course of any such work without prior
notification to the Beneficiary and unless provision is made for return or
replacement on or prior to the completion of the work. The provisions of this
SECTION 2.7.1. shall apply to any change made or required to be made by the
Trustor in the course of complying with any other of the provisions of this
Trust Deed. A duplicate set of all plans and specifications required to be filed
with any Governmental Authority prior to, or at any time in connection with, any
such alteration, demolition or new construction shall be furnished to the
Beneficiary. The Trustor will pay on demand the reasonable expenses incurred by
the Beneficiary in the review of plans and specifications provided for in this
Trust Deed.

     2.7.2. The Trustor shall have the right, at any time and from time to time,
to remove and dispose of any item of Building Service Equipment or Furnishings
which may have become obsolete or unfit for use or which is no longer useful in
the operation of the Improvements, provided that the Trustor promptly replaces
such item with other Building Service Equipment or Furnishings, free of superior
title, liens or claims (other than in favor of the Beneficiary) unless consent
of the Beneficiary is first obtained, not necessarily of the same character but
of at least equal quality, value and usefulness in connection with the operation
and maintenance of the Mortgaged Premises, provided, further, however, no
removal of any item of Building Service Equipment or Furnishings then having a
fair market value of $50,000 or more shall be made without the prior written
consent of the Beneficiary, which consent will not be unreasonably withheld or
delayed. However, if by reason of technological or other developments in the
operation and maintenance of buildings and other improvements of the general
character of the Improvements or a change in the use of the Mortgaged Premises
or any part thereof, no replacement of the Building Service Equipment or
Furnishings so removed would be necessary or desirable for the proper operation
or maintenance of the Improvements, the Trustor shall not be required to replace
the item so removed.

     2.8. Limitation on Disposition of the Mortgaged Premises.

     2.8.1. Except as expressly set forth in this Trust Deed or the Loan
Agreement (including, without limitation, SECTIONS 5.01 and 6.21 of the Loan
Agreement), the Trustor shall not directly or indirectly sell, assign, mortgage,
alienate, pledge or otherwise transfer or further encumber the Mortgaged
Premises or any part thereof or any interest therein or in any of the rents,
profits or income generated thereby, whether voluntarily, involuntarily, by
operation of law or otherwise, or lease all or any portion thereof or an
undivided interest therein, without the prior written consent of the
Beneficiary. The foregoing events are hereinafter referred as a "Transfer". Any
transfer without prior written the consent of the Beneficiary is an Event of
Default.

     2.8.2. If there shall be a violation of the terms and provisions of SECTION
2.8.1, whether by the Trustor or any other person, in addition to all other
rights and remedies available to the Beneficiary under this Trust Deed, the
Beneficiary shall have the option, by the giving of notice to the Trustor, of
declaring the entire unpaid principal balance of the Note, together with all
accrued and unpaid interest and all other sums and charges evidenced thereby or
payable pursuant to the Loan Agreement, immediately due and payable.

     2.9. Maintenance of Mortgaged Premises; Covenant Against Waste; Inspection
by the Beneficiary. The Trustor will not commit or permit waste on the Mortgaged
Premises and, at its expense, will keep and maintain the Improvements, the
Building Service Equipment and Furnishings in its (or their) present state of
repair and condition, reasonable wear and tear excepted, and, if improved, in
such improved state of repair and condition, reasonable wear and tear excepted;
provided, that this shall not limit the Trustor's other obligations hereunder,
such as compliance with laws. The Trustor shall do or cause to be done all
maintenance and make or cause to be made all repairs as may be required by the
landlord under any Space Lease. The Trustor will neither do nor permit to be
done anything to the Mortgaged Premises that may materially impair the value
thereof or which may violate any covenant, condition or restriction affecting
the Mortgaged Premises, or any part thereof, or which would effect any material
change therein or in the condition thereof that would increase the danger of
fire or other hazard arising out of the operation of the Mortgaged Premises.
Subject to the rights of Space Tenants, the

Beneficiary, and its representatives and agents, may enter and inspect the
Mortgaged Premises at any time after reasonable notice (which may be oral)
during usual business hours, and the Trustor shall, within thirty (30) days
after demand by the Beneficiary (or immediately upon demand in case of
emergency), make such repairs, replacements, renewals or additions, or perform
such items of maintenance, to the Mortgaged Premises as the Beneficiary may
reasonably require in order to cause the Mortgaged Premises to comply with the
standards established in this SECTION 2.9.

     2.10. To Furnish Certificates; Other Reporting Requirements.

     2.10.1. The Trustor will, at its own expense, deliver to the Beneficiary,
within fifteen (15) days after written request, but no more frequently than once
per six (6) month period, a written statement executed by the Trustor, in
recordable form, setting forth to the best of the Trustor's knowledge, the
amount then unpaid upon the Note and secured by this Trust Deed and stating
whether any offsets or defenses exist against the indebtedness secured hereby;
and, if any such offsets or defenses are alleged to exist, then the factual
basis and amount of such claimed offsets or defenses.

     2.10.2. The Trustor will, if requested by the Beneficiary, deliver to the
Beneficiary a certificate of an officer of the general partner of the Trustor or
of such general partner's general partner, to the effect that he is familiar
with this Trust Deed and the other Security Documents, has reviewed the affairs
of the Trustor, and to the best of his knowledge and belief there exists no
Event of Default and no act or event has occurred or exists which with notice or
lapse of time or both could become such an Event of Default, or if any such
event or Event of Default exists, specifying it and what action the Trustor is
taking to cause it to be remedied.

     2.11. After-Acquired Property. All right, title and interest of the Trustor
in and to all improvements, betterments, renewals, substitutes and replacements
of, and all additions and appurtenances to, the Mortgaged Premises hereafter
acquired, constructed, assembled or placed on the Mortgaged Premises,
immediately upon such acquisition, construction, assembly or placement, as the
case may be, and in each such case without any further mortgage, conveyance or
assignment or other act of the Trustor, shall become subject to the lien of this
Trust Deed as fully and completely, and with the same effect, as though now
owned by

the Trustor and specifically described in the granting clauses hereof; and at
any time and from time to time the Trustor, on demand, will execute, acknowledge
and deliver to the Beneficiary any and all such further assurances, mortgages,
conveyances or assignments as the Beneficiary may reasonably require to further
evidence, confirm and perfect the provisions of this SECTION 2.11.

     2.12. Further Assurances. The Trustor shall, at its sole cost and without
expense to the Beneficiary, on demand, do, execute, acknowledge and deliver all
and every such further acts, deeds, conveyances, mortgages, assignments, notices
of assignment, transfers and assurances as the Beneficiary shall from time to
time reasonably require for better assuring, conveying, assigning, transferring
and confirming unto the Beneficiary the property and rights hereby mortgaged or
assigned or intended now or hereafter so to be, or which the Trustor may be or
may hereafter become bound to convey, mortgage or assign to the Beneficiary, or
for carrying out the intention or facilitating the performance of the terms of
this Trust Deed, or for filing, registering or recording this Trust Deed.

     2.13. Recorded Instruments. The Trustor will promptly perform and observe,
or cause to be performed and observed, all of the terms, covenants and
conditions of all instruments of record affecting the Mortgaged Premises (other
than non-consensual encumbrances hereafter affecting the Mortgaged Premises, the
validity or enforceability of which the Trustor is contesting in accordance with
this Trust Deed) where non-compliance therewith affects the security of this
Trust Deed or imposes any duty or obligation upon the Trustor or any Space
Tenant. The Trustor shall do or cause to be done all things reasonably required
to preserve intact and unimpaired and to renew any and all rights-of-way,
easements, grants, appurtenances, privileges, licenses, franchises and other
interests and rights in favor of or constituting any portion of the Mortgaged
Premises. The Trustor will not, without the prior written consent of the
Beneficiary, which consent shall not be unreasonably withheld or delayed,
initiate, join in or consent to any private restrictive covenant or other public
or private restriction as to the use of all or any portion of the Mortgaged
Premises. The Trustor will, however, comply with all lawful restrictive
covenants and zoning ordinances and other public or private restrictions
affecting all or any portion of the Mortgaged Premises.

                                  ARTICLE III.

                                  Condemnation


     3.1. Notice of Taking. The Trustor shall promptly notify the Beneficiary if
the Trustor receives notice of the institution of any proceeding or negotiations
for the taking of the Mortgaged Premises, or any part thereof, whether for
permanent or temporary use and occupancy in condemnation or by the exercise of
the power of eminent domain or by agreement of interested parties in lieu of
such condemnation (all the foregoing called a "taking"); shall keep the
Beneficiary currently advised, in detail, as to the status of such proceedings
or negotiations and will promptly give to the Beneficiary copies of all notices,
pleadings, judgments, determinations and other papers received or delivered by
the Trustor in connection with any such proceedings. The Beneficiary shall have
the right to appear and participate in such proceedings and may be represented
by counsel. The Trustor will not, without the Beneficiary's prior written
consent, which consent shall not be unreasonably withheld or delayed, enter into
any agreement for the taking of the Mortgaged Premises, or any part thereof,
with anyone authorized to acquire the Mortgaged Premises by eminent domain or in
condemnation.

     3.2. Condemnation Award. If the Mortgaged Premises shall be the subject of
a taking the Beneficiary shall be entitled to and shall receive the total of
such portion of all awards made that shall be allowed to the Trustor with
respect to all the right, title and interest of the Trustor in and to the
Mortgaged Premises (the award made in any total, partial or temporary taking is
herein called the "Award"), provided that the obligations of the Trustor to
perform the terms, covenants and conditions of this Trust Deed, if any, affected
by such taking shall continue unimpaired until the actual vesting of title in
such proceeding and the actual receipt by the Beneficiary of the Trustor's share
of the entire Award resulting from such taking.

     3.3. Application of Award. The Beneficiary shall have the option of
treating a total taking or a substantial taking (as hereinafter defined) as an
Event of Default and of accelerating the entire indebtedness secured hereby, in
which event it shall apply the Trustor's entire Award in reduction of such
indebtedness (including principal, interest and other sums secured hereby, in
such order as the Beneficiary may determine) and shall turn over any balance

                                     - 27 -

remaining, if any, to the Person lawfully entitled thereto; or if the
Beneficiary shall not so elect to accelerate the indebtedness and apply the
Award thereto, then the total Award shall, regardless of amount, be deposited
with the Beneficiary or with the Depository, the Trustor hereby agreeing to
elect that such proceeds be held and disbursed by the Depository in accordance
with SECTIONS 2.5.6, 2.5.7, 2.5.8, 2.5.9 and 2.5.10 hereof for restoration
required to be made by the Trustor. If there be a partial taking, the net
proceeds of the Award shall be deposited with the Beneficiary and applied by the
Beneficiary in accordance with the provisions of SECTIONS 2.5.6, 2.5.7, 2.5.9
and 2.5.10. Any Award remaining after the completion of such restoration,
replacement or rebuilding shall be applied in reduction of the indebtedness
(including principal, interest and other sums secured hereby) in such order as
the Beneficiary shall determine. A partial taking is substantial only if it
materially decreases the fair market value of the Mortgaged Premises and the
remainder of the Mortgaged Premises cannot be restored to an economically viable
whole.

     3.4. Temporary Taking. If any Award payable to the Trustor on account of a
taking for temporary use or occupancy is made in a lump sum or is payable other
than in equal monthly installments, the Trustor shall pay over such Award to the
Depository and such Award shall be applied to installments of Impositions and of
principal and interest and all other charges secured by this Trust Deed or due
under the Note, the Loan Agreement, or the other Security Documents as and when
the same become due and payable. Any unapplied portion of such Award held by the
Depository when such taking ceases or expires (if no Event of Default has then
occurred and is continuing), or after the indebtedness secured by this Trust
Deed or due under the Loan and Security Documents shall have been paid in full,
shall be paid to the Person lawfully entitled thereto.

     3.5. The Trustor's Obligation to Restore. If all available proceeds of the
Award are made available to the Trustor for restoration, replacement or
rebuilding pursuant hereto, the Trustor shall be obligated promptly to restore,
replace, rebuild or alter any Improvements or Building Service Equipment
affected by a taking so as to restore the Mortgaged Premises to an economically
viable whole, all without regard to the adequacy of the proceeds of an Award, if
any, made available to the Trustor.

                                   ARTICLE IV.

                   Assignment of Space Leases, Rents, Profits
                   and Other Income as Further Security, Etc.


     4.1. Assignment of Space Leases, Rents, Issues and Profits. Subject to the
Trustor's rights herein, including those set forth in SECTION 4.3.2 below, the
Trustor hereby absolutely, presently and irrevocably transfers, assigns and sets
over unto the Beneficiary all right, title and interest of the Trustor in and to
all Space Leases, if any, now or hereafter entered into with respect to all or
any part of the Mortgaged Premises, and all renewals, extensions, subleases or
assignments thereof, and all other occupancy agreements (written or oral), by
concession, license or otherwise, together with all of the rents, income,
receipts, revenues, issues and profits arising therefrom (the "Collateral").

     4.2. The Trustor's Covenants Regarding Space Leases.

     4.2.1. Without the prior consent and approval of the Beneficiary in each
instance, the Trustor will not (a) assign, pledge, hypothecate or otherwise
encumber any of the Space Leases or the rents, income, issue and profits of the
Mortgaged Premises; or (b) enter into any Space Leases affecting the Mortgaged
Premises or any part thereof, unless such Space Lease is expressly subordinate
to the lien of this Trust Deed and to any consolidation, extension, renewal,
recasting or refinancing hereof and the Space Lease provides, in substance, that
in the event of enforcement by the Beneficiary of the remedies provided for by
law or by this Trust Deed, each Space Tenant shall, at the option of the
Beneficiary, enter into a agreement with the Beneficiary which shall provide,
among other things, that (i) such Space Tenant shall attorn to any person
succeeding to the interest of the Trustor as a result of such enforcement and
shall recognize such successor in interest as landlord under such Space Lease
without change in the terms or other provisions thereof, (ii) such successor
shall not be bound by any payment of rent or additional rent for more than one
(1) month in advance or any amendment or modification of any such Space Lease
made without the Beneficiary's written consent, and (iii) such successor shall
not disturb the possession of the Space Tenant provided certain conditions (as
determined by the Beneficiary) have been satisfied, including, without
limitation, that the Space Tenant shall not be in default

                                     - 29 -

under the terms of the Space Lease; or (c) enter into any Space Leases without
the prior written consent of the Beneficiary unless permitted in SECTION 6.21 of
the Loan Agreement.

     4.2.2. The Trustor further represents, warrants, covenants and agrees that:

          (a) To the best of its knowledge, each Space Lease is (or, when
     executed, will be) a valid and legally enforceable obligation of the
     parties thereto, in full force and effect.

          (b) With respect to each Space Lease and the Space Tenant security
     deposits thereunder, any and/or all of such security deposits shall be held
     as required by the Space Lease but in no event in a manner other than that
     required by law.

          (c) The Trustor shall, at its sole cost and expense, keep, observe,
     perform and discharge, duly and punctually, all and singular the material
     obligations, terms, covenants, conditions, representations and warranties
     of each Space Lease on the part of the Trustor to be kept, observed,
     performed and discharged.

          (d) (i) Except as herein in this clause (i) expressly provided, the
     Trustor shall, at its sole cost and expense, maintain the Space Leases in
     full force and effect; the Trustor will not waive its rights under or
     materially modify, change, supplement, alter or amend ("Change"), nor shall
     the Trustor surrender (whether partial or total), terminate, cancel or
     subordinate, any of the Space Leases or enter into any Backlease (whether
     through an Affiliate or otherwise), and any such attempted Change,
     surrender, termination, cancellation or subordination or Backlease shall be
     void, unless, in each case, the prior written consent thereto of the
     Beneficiary shall have been obtained. Notwithstanding the foregoing, the
     Trustor may (x) terminate any Space Lease under 10,000 rentable square feet
     as a result of a default by the tenant under such Space Lease and/or (y)
     consent to any sublease or assignment of any Space Lease under 10,000
     rentable square feet provided (aa) such termination or consent is being
     effected in the ordinary course of the Trustor's business, (bb) no Event of
     Default then exists and no event has occurred that with the passage of time
     or the giving of notice or both would

                                     - 30 -

      constitute an Event of Default, and (cc) the Beneficiary determines, in
      its reasonable discretion, that upon the effectiveness of such
      termination, assignment or sublease (i) the Loan to Value Ratio (as
      defined in the Loan Agreement, and taking into consideration the value of
      all of the Projects, as defined in the Loan Agreement) is not greater than
      55%, and (ii) the Debt Service Coverage Ratio (as defined in the Loan
      Agreement, and taking into consideration the loss of income resulting from
      such termination, assignment or sublease, as projected by the Beneficiary
      in its reasonable discretion) is not less than 1.40:1.0. A material Change
      shall include but not be limited to any material Change in the amount or
      time of payment of the rent or additional rent, the length of term or
      square footage of the premises under any Space Lease or any other Change
      which would materially adversely affect the Trustor's rights under the
      Space Lease, or would affect the Beneficiary's rights under the Space
      Lease or the value of the Space Lease as collateral security for the
      indebtedness.

               (ii) The Trustor shall, at its sole cost and expense, enforce the
          Space Leases in accordance with their terms; and shall appear in and
          defend any action or proceeding arising to which it is a party under
          or in any manner connected with any of the Space Leases.

          (e) The Trustor shall deliver to the Beneficiary a copy of each notice
     of default sent or received by it relating in any way to any Space Lease
     promptly upon, but in any event within five (5) business days after, its
     sending or receipt thereof.

     4.3. The Trustor's Rights and Powers.

     4.3.1. The Trustor hereby irrevocably, in the name of the Trustor or
otherwise, authorizes and empowers the Beneficiary, and assigns and transfers
unto the Beneficiary, and constitutes and appoints the Beneficiary its true and
lawful attorney-in-fact, coupled with an interest and as its agent, irrevocably,
with full power or substitution for it and in its name, but solely for the
following purposes: (i) to exercise and enforce every right, power, remedy,
authority, option and privilege of the Trustor under the Space Leases, and as
such attorney-in-fact, the Beneficiary may subordinate, terminate, cancel or
modify the Space Leases, accept the surrender of the Space Leases, give any
notice, take any

                                     - 31 -

action resulting in such subordination, termination, cancellation, modification
or surrender, give any authorization, furnish any information, make any demands,
execute any instruments and take any and all other action on behalf of and in
the name of the Trustor which in the opinion of the Beneficiary may be necessary
or appropriate to be given, furnished, made, exercised or taken by the Trustor
under the Space Leases in order to comply therewith, to perform the conditions
thereof or to prevent or remedy any default by the Trustor thereunder or to
enforce any of the Trustor's rights and remedies thereunder, and (ii) to ask,
require, demand, receive and collect and give acquittances for the Income (as
hereinafter defined), and on nonpayment thereof to sue for, recover and receive
the same, and on payment thereof to give sufficient releases, receipts,
discharges and acquittances thereof; to endorse any checks or other instruments
or orders in connection therewith and to file any claims or take any action or
institute any proceedings which the Beneficiary may deem to be necessary or
advisable; provided, however, that the power provided for in this sentence may
not be exercised by the Beneficiary unless an Event of Default shall have
occurred and be continuing. "Income" shall mean all deposits, rents, issues,
profits, revenues, royalties, and other revenue producing arrangements, whether
written or oral, and all monetary benefits of, and/or derived from, and/or sums
payable under and by virtue of the Space Leases and/or the Premises.

     4.3.2. So long as there shall not have occurred and then be continuing any
Event of Default and until such right of the Trustor is terminated by the
Beneficiary as provided in SECTION 4.3.3, the Beneficiary will not exercise its
rights pursuant to SECTION 4.3.1, and, notwithstanding anything in SECTION 4.3.1
to the contrary, the Trustor shall have the right (but limited as hereinafter
provided) to exercise all of its rights under the Space Leases, including,
without limitation, to collect and receive all rents, income, receipts,
revenues, issues and profits arising therefrom, provided that the Trustor shall
at all times comply with, observe and perform, in the exercise of such right,
all of the provisions of this Trust Deed and the other Security Documents
applicable to the Space Leases; provided, further, that no action shall be taken
or failed to be taken by the Trustor which would impair the Collateral or any
other collateral security for the Obligations provided for in the Security
Documents.

     4.3.3. The Beneficiary, upon the occurrence and during the continuance of
an Event of

                                     - 32 -

Default, at its option and upon written notice to the Trustor, shall have the
right to terminate the right of the Trustor to exercise its rights under the
Space Leases, and, thereupon, in addition, the Beneficiary, at any time
thereafter, at its option, shall have the complete right, power and authority
hereunder to exercise and enforce all rights, powers, remedies, authority,
options and privileges of the Trustor under the Space Leases in the name of the
Trustor or the Beneficiary, to enforce all obligations of the other parties to
the Space Leases and to exercise and enforce all of its rights and remedies
hereunder and under law not exercisable prior to an Event of Default.

     4.3.4. The Trustor does hereby direct each and all of the Space Tenants
under the Space Leases and all contractual obligors of the Trustor to pay any
Income to the Beneficiary upon written demand for payment thereof by the
Beneficiary without further inquiry. It is understood and agreed, however, that
no such demand shall be made unless an Event of Default shall have occurred and
be continuing. No such Space Tenant or obligor shall be obliged to account to
the Trustor for any amounts paid to the Beneficiary by reason of any payment
made to the Beneficiary pursuant to such demand and, upon any such payment to
the Beneficiary, shall be pro tanto released from their obligations to the
Trustor with respect to such payment. Each Space Tenant shall be permitted to
rely on any communication from the Beneficiary pursuant hereto, and under no
circumstances shall such Space Tenant be obligated to the Trustor for any
payments made to the Beneficiary hereunder. Until such demand is made, the
Trustor is authorized to collect or enforce or continue collecting or enforcing
such Income in accordance with the provisions of this Trust Deed.

     4.3.5. The Beneficiary shall not have any duty as to the collection or
protection of the Collateral or any income thereon or payments with respect
thereto, or as to the preservation of any rights pertaining thereto beyond the
safe custody of any thereof actually in its possession. In no instance shall the
Beneficiary be responsible to lessees for payment of interest upon, or return
of, any lease security deposits, except as provided by law or as provided in the
leases and then only if and to the extent that such deposits are received by the
Beneficiary. The Trustor hereby waives notice of acceptance hereof, and except
as otherwise specifically provided herein or required by provision of law which
may not be waived, hereby waives any and all notices or demands with respect to
any exercise by the Beneficiary of any rights or powers which it may have

                                     - 33 -

or to which it may be entitled with respect to the Collateral.

     4.3.6. The Trustor hereby irrevocably constitutes and appoints the
Beneficiary as the true and lawful attorney-in-fact of the Trustor, which
appointment is coupled with an interest, with full power of substitution, to
proceed from time to time in the Trustor's name in any statutory or
non-statutory proceeding affecting the Trustor or any Collateral, and the
Beneficiary or its nominee may (i) execute and file proof of claim for the full
amount of any Collateral and vote such claims for the full amount thereof (A)
for or against any proposal or resolution, (B) for a trustee or trustees or for
a receiver or receivers or for a committee of creditors and/or (C) for the
acceptance or rejection of any proposed arrangement, plan of reorganization,
composition or extension, and the Beneficiary or its nominee may receive any
payment or distribution and give acquittance therefor and may exchange or
release Collateral; (ii) endorse any draft or other instrument for the payment
of money, execute releases and negotiate and enter into settlements; and (iii)
execute all such other documents or instruments as may be necessary or expedient
to be executed by the Trustor for any of the purposes of this Trust Deed;
provided, however, that the power provided for in this sentence may be exercised
by the Beneficiary only while an Event of Default is continuing. The Beneficiary
shall have no duty to exercise any of the aforesaid rights, privileges or
options and shall not be responsible for any failure to do so or delay in so
doing.

     4.4. Remedies and Entry Upon Default.

     4.4.1. So long as no Event of Default shall have occurred and be
continuing, the Trustor shall have the right to collect (but not more than one
(1) month in advance) and retain all of the rents, gross receipts and other
payments, if any, from the Space Leases and from the Mortgaged Premises
generally, and the Beneficiary agrees that customary initial rent payments,
security deposits and reimbursements by a Space Tenant to the Trustor on account
of alterations made by the Trustor for the benefit of the Space Tenant are
permissible advance payments by the Space Tenant.

     4.4.2. Upon any Event of Default, the Beneficiary may, but shall not be
obligated to:

          (a) terminate the rights of the Trustor referred to in SECTION 4.3
     hereof and exercise all of 

                                     - 34 -

     the powers, rights and remedies provided for in SECTION 4.3 hereof,
     including those to be exercised only from and after an Event of Default;

          (b) at any time and from time to time, without notice to, or assent
     by, the Trustor or any other Person, but without affecting any of the
     Obligations, in the name of the Trustor or in the name of the Beneficiary,
     notify the account debtors and obligors on any or all of the Space Leases
     to make payment and performance directly to the Beneficiary, and demand,
     collect, receive, compound and give acquittance for the Space Leases or any
     part thereof; extend the time of payment and performance of, compromise or
     settle for cash, credit or otherwise, upon any terms and conditions, any of
     the Space Leases; endorse to the order of the Beneficiary checks, drafts or
     other orders or instruments for the payment of moneys payable to the
     Trustor which shall be issued in respect of any of the Space Leases; file
     any claims, commence, maintain or discontinue any actions, suits or other
     proceedings deemed by the Beneficiary necessary or advisable for the
     purpose of collecting upon or enforcing any of the Space Leases; and
     execute any instrument and do all other things deemed necessary and proper
     by the Beneficiary to protect and preserve and realize upon the Space
     Leases and/or the other rights contemplated hereby; the Trustor hereby
     irrevocably constitutes and appoints the Beneficiary as such the Trustor's
     lawful attorney-in-fact, coupled with an interest, and its agent for the
     foregoing purposes;

     Premises or any part or part thereof, and also any and all other charges,
     costs and expenses which the Beneficiary deems necessary or advisable to
     pay in respect of the management or operation of the Premises, including,
     without limitation, the costs of insurance policies, repairs and
     alterations, commissions for renting the Premises or any part or parts
     thereof, legal expenses in enforcing claims, preparing papers or procuring
     any other services that may be required and any amounts payable under or
     pursuant to any Lease; all amounts so paid and expended shall be payable on
     demand, together with interest at the Involuntary Rate from the date
     incurred until paid, and be deemed to be included within the Obligations
     and secured by this Trust Deed; the provisions of this ARTICLE and the
     rights given to the Beneficiary hereby shall inure to the benefit of the
     Beneficiary even though the Beneficiary does not enter and take possession
     of the Premises; any balance remaining after the indebtedness secured
     hereby and the other obligations of the Trustor under the Loan and Security
     Documents shall have been paid in full shall be turned over to the Person
     lawfully entitled thereto. Neither the entry upon and taking possession of
     the Mortgaged Premises, nor the collection and application of the rents,
     gross receipts or other charges thereof, nor any other action taken by the
     Beneficiary in connection therewith, shall cure or waive any default
     hereunder or waive or modify any notice thereof or notice of acceleration
     of the Note theretofore given by the Beneficiary.

     4.4.3. If an Event of Default shall have occurred and be continuing, a
notice in writing by the Beneficiary to the Space Tenants under the Space Leases
advising them that the Trustor has defaulted hereunder and requesting that all
future payments of rent, additional rent or other charges under the Space Leases
be made to the Beneficiary (or its agent) shall be construed as conclusive
authority to such Space Tenants that such payments are to be made to the
Beneficiary (or its agent). Each Space Tenant shall be fully protected in making
such payments to the Beneficiary (or its agent) and be given full credit against
its obligations under the applicable Space Lease to the extent of payments made
to the Beneficiary (or its agent) pursuant to any such notice; and the Trustor
hereby irrevocably constitutes and appoints the Beneficiary the attorney-in-fact
and agent of the Trustor, coupled with an interest, for the purpose of endorsing
the consent of the Trustor on any such notice.

     4.5. No Obligation of Beneficiary.

     4.5.1. The Beneficiary shall not be obligated to perform or discharge any
obligation of the Trustor as a result of the assignment hereby effected, and the
Trustor hereby agrees to indemnify and hold the Beneficiary harmless from and
against any and all liability, loss or damage which the Beneficiary may incur by
reason of any act of the Beneficiary under this Trust Deed, other than as a
result of the Beneficiary's willful misconduct or gross negligence and other
than as a result of the Beneficiary's misconduct or negligence after the
Beneficiary has taken possession of the Premises. Should the Beneficiary (i)
incur any such liability, loss or damage by reason of this Trust Deed and which
is covered by the foregoing indemnity, or in defense against any such claims or
demands, or (ii) perform any acts or covenants on the part of the Trustor to be
performed under the Space Leases, or (iii) pay for the account of the Trustor
(other than from Income or from funds delivered to the Beneficiary by the
Trustor to be held in trust for such purpose), any and all sums, costs and
expenses for the discharge of taxes, assessments, water rents or other liens
against the Collateral or any part thereof, or on account of insurance premiums
or repairs, and also any amounts and expenses necessary to perform any covenants
and conditions to be performed on the part of the Trustor under the Space
Leases, the amount thereof, including costs, expenses and reasonable attorneys'
fees, together with interest thereon at the Involuntary Rate from the date such
expenses were paid by the Beneficiary to the date of payment to the Beneficiary
by the Trustor, shall be included in the Obligations secured by this Trust Deed,

     4.5.2. The acceptance by the Beneficiary of this Trust Deed, with all the
rights, powers, privileges and authority so created, shall not at any time or in
any event obligate the Beneficiary to appear in or defend any action or
proceeding relating to the Collateral, or to take any action hereunder or
thereunder, or to expend any money or incur any expenses or perform or discharge
any obligation, duty or liability under the Collateral.

                Security Agreement Under Uniform Commercial Code

     5.1. This Trust Deed shall constitute a security agreement and a fixture
filing within the meaning of the Uniform Commercial Code of the State (the
"Code"), and the Beneficiary shall be deemed to be the "secured party" (as that
term is defined in the Code). The Trustor hereby grants to the Beneficiary, as
additional collateral for the obligations under the Note and the other
Obligations secured hereby, a security interest in and to all of the Mortgaged
Premises which are considered or as shall be determined to be personal property
or "fixtures" (as defined in the Code), including, without limitation, the
Building Service Equipment, the Furnishings, the Payments and Intangibles, all
books, records, licenses and certificates of the Trustor relating to the
Mortgaged Premises, together with all replacements thereof, substitutions
therefor or additions thereto (said property being sometimes hereinafter
referred to as the "Personal Property"). The Trustor agrees that a security
interest shall attach to the Personal Property for the benefit of the
Beneficiary to secure the indebtedness evidenced by the Note and the other
Obligations secured by this Trust Deed and all other sums and charges which may
become due hereunder, thereunder or under any of the other Security Documents.
The Trustor hereby authorizes the Beneficiary to file financing and continuation
statements with respect to the Personal Property without the signature of the
Trustor, if permitted by the Code. In any event the Trustor covenants to execute
such financing and continuation statements as the Beneficiary may reasonably
request. If an Event of Default shall occur and be continuing, the Beneficiary,
pursuant to the appropriate provisions of the Code, shall have the option of
proceeding as to both real and personal property in accordance with its rights
and remedies in respect of real property under this Trust Deed and the law of
the State, in which event the default provisions of the Code shall not apply.
The Trustor agrees that, in the event the Beneficiary shall elect to proceed
with respect to the Personal Property separately from the real property, unless
a greater period shall then be mandated by the Code, five (5) days notice of the
sale of the Personal Property shall be reasonable notice. The expenses of
retaking, holding, preparing for sale and selling incurred by the Beneficiary
shall be assessed against the Trustor and shall include, but not be limited to,
the reasonable legal expenses incurred by Beneficiary. The Trustor agrees that
it will not remove or permit to be removed from the Mortgaged Premises any of
the Personal

Property without the prior written consent of the Beneficiary except as set
forth in SECTION 2.7.2. All replacements, renewals and additions to the Personal
Property shall be and become immediately subject to the security interest of
this Trust Deed and the provisions of this ARTICLE V. The Trustor warrants and
represents that all Personal Property now is free and clear of all liens,
encumbrances or security interests other than the Permitted Encumbrances, and
that all replacements of the Personal Property, substitutions therefor or
additions thereto, unless the Beneficiary otherwise consents, will be, free and
clear of liens, encumbrances or security interests of others.


                                   ARTICLE VI.

                         Events of Default and Remedies


     6.1. Events of Default. The whole of the outstanding Principal Amount (as
defined in the Note) and accrued interest evidenced by the Note shall, at the
option of the Beneficiary, become due upon the happening of an Event of Default;
provided, however, that upon the occurrence of a default specified in SECTIONS
5.01(f) or 5.01(g) of the Loan Agreement, or upon the occurrence of any other
default specified in any Loan Document (as defined in the Loan Agreement) where
provision is made for acceleration to occur automatically as a consequence
thereof, all sums owing to the Beneficiary thereunder shall automatically become
immediately due and payable.

     6.2. Remedies. If an Event of Default shall occur and be continuing, the
Beneficiary, at its option, may:

     6.2.1. by notice to the Trustor, declare the entire principal amount of the
Note then outstanding and all accrued and unpaid interest thereon and all
obligations of the Trustor to the Beneficiary to be immediately due and payable,
and upon such declaration such principal and interest and all obligations of the
Trustor to the Beneficiary shall become and be immediately due and payable,
anything in the Note, the Loan Agreement or in this Trust Deed or in any of the
other Security Documents to the contrary notwithstanding;

     6.2.2. as a matter of right and without notice to the Trustor or anyone
claiming under the Trustor,

and without regard to the then value of the Mortgaged Premises or the interest
of the Trustor therein, to apply to any court having jurisdiction to appoint a
receiver or receivers of the Mortgaged Premises, and the Trustor hereby
irrevocable consents to such appointment and waives notice of any application
therefor; any such receiver or receivers shall have all the usual powers and
duties of receivers in like or similar cases and all the powers and duties of
the Beneficiary in case of entry as provided in this Trust Deed, and shall
continue as such and exercise all such powers until the later of (i) the date of
confirmation of sale of the Mortgaged Premises, (ii) the disbursement of all
proceeds of the Mortgaged Premises collected by such receiver and the payment of
all expenses incurred in connection therewith, and (iii) the termination of such
receivership with the consent of the Beneficiary or pursuant to an order by a
court of competent jurisdiction;

     6.2.3. exercise any and all remedies available to a secured party under the
UCC in such order and in such manner as the Beneficiary in its sole discretion
may determine; provided, however, that the expenses of retaking, holding,
preparing for sale or the like, shall include reasonable attorneys' fees and
other expenses of the Beneficiary and the Trustee and be secured by this Trust
Deed;

     6.2.4. bring an action in any court of competent jurisdiction to foreclose
this Trust Deed or enforce any of the terms, covenants and conditions hereof or
contained in any other Security Document;

     6.2.5. elect to cause the Mortgaged Premises or any part thereof to be sold
as follows:

          (a) deliver to the Trustee a written declaration of default and demand
     for sale, and a written notice of default and election to cause the
     Trustor's interest in the Mortgaged Premises, or any portion thereof, to be
     sold, which notice the Trustee or the Beneficiary shall cause to be duly
     filed for record in the Official Records of the County in which the
     Mortgaged Premises is located;

          (b) upon receipt of such notice from the Beneficiary, the Trustee
     shall cause to be recorded, published and delivered to the Trustor, such
     Notice of Default and Election to Sell as then required by law and by this
     Trust Deed, the Trustee shall, without demand on the Trustor, after lapse
     of such time as may then be required by

     law, and after recordation of such Notice of Default and after Notice of
     Sale having been given as required by law, sell the Mortgaged Premises at
     the time and place of sale fixed by it in said Notice of Sale, either as a
     whole, or in separate lots or parcels or items as the Beneficiary shall
     deem expedient, and in such order as the Beneficiary may determine, at
     public auction to the highest bidder for cash in lawful money of the United
     States payable at the time of sale; the Trustor hereby expressly waives any
     right which it may have to direct the order in which any of the Mortgaged
     Premises may be sold when it consists of more than one lot or parcel, and
     such order of sale, whether in a single sale or in multiple sales held on
     different days or at different times, shall be at the sole discretion of
     the Beneficiary; the Trustee shall deliver to such purchaser or purchasers
     thereof its good and sufficient deed or deeds conveying the property so
     sold, but without any covenant or warranty, express or implied; the
     recitals in such deed of any matters or facts shall be conclusive proof of
     the truthfulness thereof; and any Person, including, without limitation,
     the Trustor, the Trustee or the Beneficiary, may purchase at such sale;

          (c) after deducting all costs, fees and expenses of the Trustee,
     including costs of evidence of title and attorneys' fees of the Trustee and
     the Beneficiary in connection with such sale, the Trustee shall apply, in
     the following priority, the proceeds of sale to payment of: (i) first, all
     sums expended under the terms hereof, not then repaid, with interest
     thereon at the Involuntary Rate, (ii) second, all other sums then secured
     hereby, in such order of priority and in such proportion as the Beneficiary
     in its sole discretion may elect, and (iii) the remainder, if any, to the
     Person lawfully entitled thereto;

          (d) subject to applicable law, the Trustee may postpone the sale of
     all or any portion of the Mortgaged Premises, by public announcement at the
     time and place of such sale, and from time to time thereafter may postpone
     such sale by public announcement at the time fixed by the preceding
     postponement or subsequently noticed sale, and without further notice make
     such sale at the time fixed by the last postponement, or may, in its
     discretion, give a new notice of sale;

     6.2.6. exercise any or all of its other rights and remedies provided
herein, in any of the Security Documents, or other document or agreement now or
hereafter securing all or any portion of the Obligations secured

hereby, or as provided by law, in such order of priority as the Beneficiary
shall determine in its sole discretion.

     6.3. Sale; No Marshalling of Assets.

     6.3.1. In case of a foreclosure sale, all of the Mortgaged Premises may be
sold in one parcel even though the proceeds of such sale exceed or may exceed
the indebtedness secured hereby. The Beneficiary shall not be required to
exercise any rights under this Trust Deed before proceeding against any other
security, shall not be required to proceed against other security before
proceeding under this Trust Deed, and shall not be precluded from proceeding
against any or all of any security held by the Beneficiary for any or all of the
indebtedness secured hereby in any order or at the same time.

     6.3.2. The Trustor agrees, to the full extent that it may lawfully do so,
that in any foreclosure or other action brought by the Beneficiary to enforce
this Trust Deed, it will not at any time insist upon or plead or in any way take
advantage of any appraisement, valuation, stay, marshalling of assets,
extension, redemption or moratorium law now or hereafter in force and effect so
as to prevent, hinder, delay or otherwise affect the enforcement of the
provisions of this Trust Deed or any rights or remedies the Beneficiary may have
hereunder or by law.

     6.3.3. If the Beneficiary shall elect to accelerate the indebtedness
secured hereby following the occurrence of an Event of Default, the Trustor,
within five (5) days after demand, will pay to the Beneficiary, or any receiver
appointed in connection with the foreclosure of this Trust Deed, any and all
amounts then held as security deposits under all Space Leases; and the
Beneficiary or such receiver shall be deemed to indemnify the Trustor against
all claims of tenants in respect of the security deposits so paid following such
demand.

     6.4. Legal Expenses of the Beneficiary.

     6.4.1. The Trustor will pay to the Beneficiary or the Trustee, as the case
may be, on demand, all costs, charges and expenses (including, without
limitation, reasonable attorneys' fees and disbursements) incurred or paid at

proceeding to foreclose this Trust Deed or to recover or collect all, or any
portion of the indebtedness secured hereby; and (ii) in connection with any
modification or amendment or assignment

of this Trust Deed or the other Security Documents, together with interest on
each such payment made by the Beneficiary at the Involuntary Rate from the date
of the Beneficiary's demand for such payment to the date of reimbursement by the
Trustor.

     6.4.2. If any action or proceeding be commenced in which the Beneficiary or
the Trustee is made a party, or in which it becomes necessary to defend or
uphold the lien of this Trust Deed, all reasonable sums paid by the Beneficiary
for the expense of any litigation to prosecute or defend the title, rights and
lien created by this Trust Deed (including, without limitation, reasonable
attorneys' fees) shall be paid by the Trustor, together with interest thereon at
the Involuntary Rate from the date of the Beneficiary's demand for such payment
to the date of reimbursement by the Trustor.

     6.5. Remedies Cumulative; No Waiver; Etc.

     6.5.1. No remedy in this Trust Deed conferred upon or reserved to the
Beneficiary is intended to be exclusive of any other remedy or remedies, and
each and every such remedy shall be cumulative, and shall be in addition to
every other remedy given hereunder or now or hereafter existing at law or in
equity. No delay or omission by the Beneficiary in exercising any right or power
arising upon any Event of Default shall impair any such right or power, or shall
be construed to be a waiver of or acquiescence in any such Event of Default; and
every power and remedy given by this Trust Deed to the Beneficiary may be
exercised from time to time as often as the Beneficiary may determine it is
appropriate to do so.

     6.5.2. A waiver in one or more instances of compliance with any of the
terms, covenants, conditions or provisions of the Note, the Loan Agreement or of
the Security Documents shall apply to the particular instance or instances and
at the particular time or times only, and no such waiver shall be deemed a
continuing waiver. In any event, no waiver shall be effective, or be asserted by
the Trustor as having been made, unless set forth in a writing signed by the
Beneficiary.

     6.5.3. The Trustor waives and renounces all homestead and similar exemption
rights with respect to the Mortgaged Premises provided for by the Constitution
and laws of the United States and of the State as against the collection of the
Security Documents, or any part thereof.

     6.6. No Merger. It is the intention of the parties to this Trust Deed that
if the Beneficiary or the Trustee shall at any time hereafter acquire title to
all or any portion of the Mortgaged Premises, then, and until the indebtedness
secured hereby has been paid in full, the interest of the Beneficiary hereunder
and the lien of this Trust Deed shall not merge or become merged in or with the
estate and interest of the Beneficiary or the Trustee as the holder and owner of
title to all or any portion of the Mortgaged Premises and that, until such
payment, the estate of the Beneficiary or the Trustee in the Mortgaged Premises
and the lien of this Trust Deed and the interest of the Beneficiary hereunder
shall continue in full force and effect to the same extent as if the Beneficiary
or the Trustee had not acquired title to all or any portion of the Mortgaged
Premises.

communications (each, a "Notice") given or required to be given hereunder shall
be sent to the addresses and in the manner required by the Loan Agreement.

     7.3. The Beneficiary's Rights to Perform the Trustor's Covenants. If the
Trustor shall fail to pay or cause payment to be paid to the Beneficiary in
accordance with the terms of the Security Documents, or to perform or observe
any other term, covenant, condition or obligation required to be performed or
observed by the Trustor under this Trust Deed or the other Security Documents,
without limiting any other provision of this Trust Deed, and without waiving or
releasing the Trustor from any obligation or default hereunder, after giving any
notice to the Trustor required hereunder and after the passage of any applicable
cure periods (or without such notice in the event of an emergency), the
Beneficiary (or any receiver of the Mortgaged Premises) shall have the right,
but not the obligation, to make any such payment, or to perform any other act or
take any appropriate action, including, without limitation, entry on the
Mortgaged Premises and performance of work thereat, as it, in its sole
discretion, may deem necessary to cause such other term, covenant, condition or
obligation to be promptly performed or observed on behalf of the Trustor or to
protect the security of this Trust Deed. All amounts advanced by, or on behalf
of, the Beneficiary in exercising its rights under this SECTION 7.3 (including,
but not limited to, legal expenses and disbursements incurred in connection
therewith), together with interest thereon at the Involuntary Rate from the date
of the Beneficiary's demand upon the Trustor for reimbursement of such sums
until reimbursement by the Trustor, shall be payable by the Trustor to the

the Note or such other Security Documents, be added to and deemed part of the
indebtedness secured by the lien of this Trust Deed whether or not the provision
which obligates the Trustor to make any such payment to the Beneficiary
specifically so states.

     7.5. Captions. The captions used in this Trust Deed are inserted only as a
matter of convenience and for reference, and in no way define, limit, enlarge or
describe the scope or intent of this Trust Deed or in any other way affect this
Trust Deed or the construction of any provision hereof.

     7.6. Successors and Assigns. The covenants and agreements contained in this
Trust Deed shall run with the land and bind the Trustor, the successors and
assigns of the Trustor and all subsequent owners, encumbrances and Space Tenants
of the Mortgaged Premises, or any part thereof; and shall inure to the benefit
of the Beneficiary, its successors and assigns and all subsequent beneficial
owners of this Trust Deed.

     7.7. Gender and Number. Wherever the context of this Trust Deed so
requires, the neuter gender includes the masculine and/or feminine gender and
the singular number includes the plural.

     7.8. Severability. If any one or more of the provisions contained in this
Trust Deed shall for any reason be held to be invalid, illegal, or unenforceable
in any respect, such invalidity, illegality or unenforceability shall not affect
any other provisions of this Trust Deed; and this Trust Deed shall, in such
event, be construed as if such invalid, illegal or unenforceable provision had
never been included.

     7.9. Usury. Anything in the Note, the Loan Agreement, this Trust Deed or
the other Security Documents to the contrary notwithstanding, the Beneficiary
shall never be entitled to receive, collect or apply as interest on the
principal amount of the Note or any other of the obligations secured hereby any
amount in excess of the maximum rate of interest permitted to be charged by
applicable law. In the event the Beneficiary ever receives, collects or applies
as interest any such excess, the amount which would be excessive interest shall
be applied to the reduction of the principal amount of said obligations; and if
said principal amount shall have been paid in full, shall be remitted to the
Person lawfully entitled thereto. In determining whether or not the interest
paid or payable in any specific instance shall exceed the highest lawful rate,

     2.3.1. This Trust Deed is and will be maintained as a valid first lien deed

Mortgaged Premises or any portion thereof, or against the rents, issues and

filed against the Mortgaged Premises, or any part thereof, the Trustor promptly
shall discharge the lien of record, by bonding or otherwise. The Trustor shall
exhibit to the Beneficiary, upon request, appropriate receipts or other
satisfactory evidence of the payment of the Impositions or any other item which

payable, all Impositions levied upon the Mortgaged Premises or any part thereof.

installments (whether or not interest shall accrue on the unpaid balance
thereof), the Trustor shall have the right to exercise such option and to pay
such Imposition, or cause it to be paid (together with any accrued interest on
the unpaid balance) in installments as they fall due and before any fine,
penalty, further interest or cost may be added thereto.

     2.4.2. If an Event of Default shall occur and be continuing, then upon
demand of the Beneficiary, the

Trustor shall deposit with the Beneficiary a sum which bears the same relation
to the annual insurance premiums for all insurance required by the terms hereof
and real estate taxes and assessments assessed against the Mortgaged Premises
for the insurance period or tax year then in effect, as the case may be, as the
number of months elapsed as of the date of such demand since the last preceding
installment of said premiums or taxes or assessments shall have become due and
payable bears to twelve (12). For the purpose of this computation, the month in
which such last preceding installment of premiums or real estate taxes or
assessments became due and payable and the month in which such demand is given
shall be included and deemed to have elapsed. On the first day of the month next
succeeding the month in which such demand is given, and thereafter on the first
day of each and every month during the term of this Trust Deed, the Trustor
shall deposit with the Beneficiary a sum equal to one-twelfth of such insurance
premiums and such taxes and assessments for the then-current insurance period
and tax year, so that as each installment of such premiums and taxes and
assessments shall become due and payable, the Trustor shall have deposited with
the Beneficiary a sum sufficient to pay the same. All such deposits shall be
received and held as part of such deposit by the Beneficiary (all such deposits
to be held in an account without interest thereon) and shall be applied to the
payment of each installment of such premiums and taxes and assessments as they
shall become due and payable. The Beneficiary shall, upon demand, furnish
evidence to the Trustor of the making of each such payment. If the amount of
such premiums and taxes and assessments has not been definitely ascertained at
the time when any such monthly deposits are required to be made, the Trustor
shall make such deposits based upon the amount of such premiums and taxes and
assessments for the preceding year, subject to adjustment as and when the amount
of such premiums and taxes and assessments are ascertained. If at any time when
any installment of such premiums and such taxes and assessments becomes due and
payable the Trustor shall not have deposited a sum sufficient to pay the same,
the Trustor shall, within five (5) days after demand, deposit any deficiency
with the Beneficiary. Upon payment in full of the indebtedness secured by this
Trust Deed, any remaining amount on deposit with the Beneficiary shall be repaid
to the Person lawfully entitled thereto. If an Event of Default shall occur and
be continuing, the Beneficiary may, at its option, apply all or any portion of
the amounts then on deposit with the Beneficiary pursuant to this SECTION 2.4.2
first to the payment of any premiums, taxes or assessments then due, and any
remaining amounts may be applied to the payment of the indebtedness. The Trustor

shall deliver to the Beneficiary all insurance and tax bills promptly following
receipt during any period when such monthly deposits are to be made with the
Beneficiary.

     2.4.3. The Trustor will pay all taxes and other governmental charges
(including, without limitation, stamp taxes), except income or franchise taxes
or similar taxes based upon or measured by income, assessed by the United States
government or any state or local governmental authority and imposed on the
Beneficiary, its successors by reason of the ownership of this Trust Deed or the
Note or the receipt of the interest or other sums payable thereunder or payable
by either the Trustor or the Beneficiary upon any increase in the indebtedness
secured hereby, or any modification, amendment, extension or consolidation of
this Trust Deed. Without limiting the foregoing and subject to the limitations
set forth above, the Trustor will also pay the whole of any tax imposed,
directly or indirectly, on this Trust Deed or the Note or the receipt of any
portion of the Indebtedness in lieu of a tax on the Mortgaged Premises or the
Improvements and Building Service Equipment, whether by reason of (a) the
passage after the date of this Trust Deed of any law of the State deducting from
the value of real property for the purposes of taxation any lien thereon; (b)
any change in the laws for the taxation of Trust Deeds or debts secured by trust
deeds for state or local purposes; (c) a change in the means of collection of
any such tax or otherwise; or (d) any tax, whether or not now existing, assessed
against, or withheld from, interest or other payments made by the Trustor or
assessed against this Trust Deed and which are assessed or levied by the
government of any foreign nation or political subdivision thereof, provided such
tax liability shall not result from the ownership of this Trust Deed by a Person
not a citizen of, or an entity not formed under the laws of, the United States
or any state. Within a reasonable time after payment of any such tax or
governmental charge, the Trustor will deliver to the Beneficiary satisfactory
proof of payment thereof, subject, however, to the right of the Trustor to
contest Impositions as hereinafter set forth. If the Trustor shall fail to pay
such tax or charge within fifteen (15) days after written notice, or if under
applicable law the Trustor's payment or agreement to pay the same shall be
unenforceable, the Beneficiary shall have the right to declare the entire unpaid
indebtedness and all accrued and unpaid interest thereon due and payable on a
date specified by the Beneficiary, but, in any event, not less than thirty (30)
days after written notice to the Trustor.

     2.4.4. The Trustor shall have the right to contest the amount or validity,
in whole or in part, of any Imposition, or to seek a reduction in the valuation
of the Mortgaged Premises, or any part thereof, as assessed for real estate or
personal property tax purposes by appropriate proceedings diligently conducted
in good faith, but only after payment of such Imposition, unless such payment
would operate as a bar to such contest or materially adversely interfere with
the prosecution thereof, in which event the Trustor may postpone or defer
payment of such Imposition (but not the payment of any monthly deposits pursuant
to SECTION 2.4.2 hereof); and upon request by the Trustor, the Beneficiary shall
postpone or defer payment of such Imposition; provided, however, that if at any
time the Mortgaged Premises, the Building Service Equipment, the Furnishings, or
any part thereof would, in the Beneficiary's reasonable judgment, by reason of
such postponement or deferment be in imminent danger of being forfeited or lost,
or if the Beneficiary might be subjected to any civil or criminal liability or
other sanction, then the Trustor, on demand, shall immediately pay or cause to
be paid the amount so contested and unpaid, together with all interest and
penalties in connection therewith.

     2.4.5. The certificate, advice or bill of the appropriate official
designated by law to make or issue the same or to receive payment of any
Imposition indicating the nonpayment of such Imposition shall be prima facie
evidence that such Imposition is due and payable but unpaid at the time of the
making or issuance thereof.

     2.5. Insurance; Restoration Following Casualty.

     2.5.1. Until the indebtedness secured hereby is paid in full, the Trustor
shall at its own expense at all times maintain or cause to be maintained on all
of the Mortgaged Premises (a) comprehensive general liability insurance,
including umbrella liability insurance, covering all claims for bodily injury,
including death, and property damage occurring on, in or about the Mortgaged
Premises in an aggregate amount of not less than Five Million Dollars
($5,000,000) per occurrence, and a single limit of not less than Two Million
Dollars ($2,000,000) per person and per occurrence for personal injury, bodily
injury and property damage; the policy shall have no deductible or self insured
retention requirements; the policy limits of such insurance, if requested by the
Beneficiary, shall be increased from time to time to reflect what a reasonably
prudent owner or lessee of buildings or improvements similar in type and
locality to the Mortgaged Premises would carry; during any

                                     - 13 -

period of substantial alterations or improvements in, on or to the Mortgaged
Premises, the Trustor will cause the comprehensive general liability insurance,
including umbrella liability insurance, endorsed to provide owners' and
contractors' protective liability coverage, including completed operations
liability coverage; (b) physical damage insurance (all risk non-reporting
property insurance, including earthquake insurance, with the Beneficiary named
as loss payee), covering the Mortgaged Premises for loss or damages resulting
from the perils of fire, lightning, earthquake, and such other risks and hazards
as are provided under the current standard "Extended Coverage Endorsement" and
vandalism and malicious mischief coverage, for the full replacement value of the
Mortgaged Premises on a stipulated and agreed-amount basis; (c) if the Mortgaged
Premises is in an area identified as a flood hazard area by the Secretary of
Housing and Urban Development, flood insurance, to the extent obtainable, in an
amount equal to the lesser of the full replacement value of the Mortgaged
Premises or the maximum amount available under the Federal flood insurance
program; (d) boiler and machinery insurance covering all boilers, machinery, air
conditioning, pressure vessels, and similar type equipment commonly covered
under a broad-form boiler and machinery policy, in an amount satisfactory to the
Beneficiary; (e) insurance against such other risks of damage, hazards,
casualties and contingencies in such amounts as the Beneficiary shall from time
to time reasonably require, provided that insurance against such other risks,
hazards, casualties or contingencies shall then be commonly carried by prudent
owners or lessees of building or improvements in the locality similar in
character, construction, use and occupancy to the Improvements, Building Service
Equipment and Furnishings on, or constituting a part of, the Mortgaged Premises;
and (f) loss of rents/business interruption coverage in an amount sufficient to
pay all Impositions, insurance premiums, interest and principal installments and
all other amounts due under the Note and the Loan Agreement and the normal
operating expenses of the Mortgaged Premises, all for a period of one (1) year.
Furthermore, the Beneficiary reserves the right to require additional insurance
and/or higher policy limits than heretofore specified if such additional
insurance and/or higher policy limits are commercially reasonable for similar
properties, which right may be exercised by written notice to the Trustor, and,
as soon thereafter as practicable, but in any event within thirty (30) days of
the receipt thereof, the Trustor agrees to obtain insurance coverage complying
with such notice. The proceeds of all such insurance (except the insurance
specified in SECTION 2.5.1(a)) shall be paid solely to the

                                     - 14 -

Beneficiary and be held, applied or disbursed by the Beneficiary as provided in
SECTIONS 2.5.7 and 2.5.8.

     2.5.2. All insurance required in SECTION 2.5.1 shall be evidenced by valid
and enforceable policies, in form and substance as shall be required by the
Beneficiary from time to time, and issued by and distributed among insurers of
recognized responsibility having an A.M. Best's Guide of A:XII or better, a
financial size category of Class XI or above, and the total limit of liability
shall not exceed ten percent (10%) of the total policyholders' surplus. Such
insurers shall be authorized to do business in the State and in all other
respects shall be reasonably satisfactory to the Beneficiary. The originals of
all such policies, or duplicate copies or certificates thereof, shall be
delivered to the Beneficiary concurrently with the execution and delivery of
this Trust Deed. Thereafter, all renewal or replacement policies, or duplicate
copies or certificates thereof, shall be delivered to the Beneficiary not less
than thirty (30) days prior to the expiration date of the policy or policies to
be renewed or replaced, in each case accompanied by evidence reasonably
satisfactory to the Beneficiary that all premiums currently payable with respect
to such policies have been paid in full by or at the direction of the Trustor.

     2.5.3. All such insurance policies shall (a) except for any liability
policy required hereunder, contain a standard noncontributory form of mortgagee
clause (in favor of and entitling the Beneficiary to collect any and all
proceeds payable under such insurance), as well as a standard waiver of
subrogation endorsement, all to be in form and substance reasonably satisfactory
to the Beneficiary; (b) provide that such policies may not be cancelled or
amended without at least thirty (30) days prior written notice to the
Beneficiary; and (c) provide that no act, omission or negligence of the Trustor,
or its agents, servants or employees, or of any Space Tenant under any Space
Lease, which might otherwise result in a forfeiture of such insurance or any
part thereof, shall in any way affect the validity or enforceability of such
insurance insofar as the Beneficiary is concerned. The Trustor shall not carry
separate insurance, concurrent in kind or form or contributing in the event of
loss with any insurance required under this SECTION 2.5. All losses under such
insurance policies shall be adjusted by the Trustor in the case of any single
instance of such damage or destruction not exceeding $200,000, by the Trustor
and the Beneficiary in the case of any such single instance of damage or
destruction exceeding such amount, provided that in no event

                                     - 15 -

shall the Trustor approve or consent to any final adjustment in any amount
exceeding the amount specified above in this sentence without obtaining the
Beneficiary's prior approval (which approval shall not be unreasonably withheld)
of the amount of such adjustment, and solely by the Beneficiary in the case when
an Event of Default exists and is continuing.

     2.5.4. The Trustor, at its expense, will furnish to the Beneficiary, within
ninety (90) days after written demand, but in no event, except for reasonable
cause, more frequently than annually, proof of the then full replacement value
of each of the Improvements and the Building Service Equipment and Furnishings
therein, such proof to be by appraisals reasonably satisfactory in form and
substance to the Beneficiary and prepared by an appraiser (who may be an
appraiser for the insurance company insuring such property) designated and paid
for by the Trustor and approved by the Beneficiary, which approval shall not be
unreasonably withheld or delayed.

     2.5.5. If the Beneficiary shall, by any means, acquire the title or estate
of the Trustor in or to any portion of the Mortgaged Premises, it shall
thereupon become the sole and absolute owner of all insurance policies affecting
such portion of the Mortgaged Premises held by, or required hereunder to be
delivered to, the Beneficiary, with the sole right to collect and retain all
unearned premiums thereon; and the Trustor shall be entitled only to a credit in
reduction of the then outstanding indebtedness secured hereby in the amount of
the short rate cancellation refund, when and if received by Beneficiary. The
Trustor agrees, immediately upon demand, to execute and deliver such assignments
or other authorizations or instruments as may, in the reasonable opinion of the
Beneficiary, be reasonably necessary or desirable to effectuate any of the
provisions of this SECTION 2.5.5.

     2.5.6. If any of the Improvements, Building Service Equipment or
Furnishings shall be damaged or destroyed, in whole or in part, by fire or other
casualty, the Trustor shall give prompt notice thereof to the Beneficiary, and,
without regard to the availability or adequacy of insurance proceeds, shall
promptly following receipt of any insurance proceeds or the date when any such
proceeds are made available to the Trustor in accordance with the terms hereof,
commence to restore, replace, rebuild or alter the same as nearly as possible to
the condition, character and value thereof existing immediately prior to such
damage or destruction. Any insurance proceeds in respect of such damage or
destruction, or any Award (as

defined in SECTION 3.2) for a partial taking which is not a substantial or total
taking, as such terms are referred to in ARTICLE III hereof, at the option of
the Beneficiary, may either (i) be applied as a prepayment of the unpaid balance
of the principal of the Note and of accrued and unpaid interest thereon and as a
payment of any other sums due and owing under the Note, the Loan Agreement and
the Security Documents, or (ii) be made available to pay or reimburse costs
incurred for restoration, replacement or rebuilding necessitated as a result of
such damage or destruction, or as a result of such taking, as the case may be,
or (iii) be used for any other purpose or object deemed appropriate by the
Beneficiary in connection with the Mortgaged Premises, provided, however, that
the Beneficiary may not elect either option (i) or (iii) above if, and for so
long as all of the following conditions (collectively, the "Insurance or Award
Conditions" have been and remain satisfied: (a) no Event of Default has occurred
and is continuing or would occur as a result of such casualty or taking and no
event has occurred that with the passage of time or the giving of notice, or
both, would constitute an Event of Default; (b) the balance of the insurance
proceeds or such Award either initially paid to the Beneficiary or deposited
with the Depository (as hereinafter defined) or remaining from time to time,
shall be sufficient, in the Beneficiary's reasonable judgment, to complete the
restoration, replacement or rebuilding, or the Trustor shall have deposited such
sufficient funds with the Beneficiary or the Depository; and (c) the Beneficiary
determines, in its reasonable discretion, that (i) the Loan to Value Ratio (as
defined in the Loan Agreement, and taking into consideration the value of all of
the Projects, as defined in the Loan Agreement) is not greater than 55%, and
(ii) the Debt Service Coverage Ratio (as defined in the Loan Agreement, and
taking into consideration the loss of income resulting from such damage or
destruction as projected by the Beneficiary in its reasonable discretion) is not
less than 1.40:1.0. Notwithstanding the foregoing, if an event has occurred and
is continuing that with the passage of time or the giving of notice, or both,
would constitute an Event of Default but the same has not yet matured into an
Event of Default, then, if the conditions set forth in the foregoing clauses (b)
and (c) have been or will be, in the Beneficiary's reasonable judgment,
satisfied, the Beneficiary shall not elect either option (i) or (iii) unless
such event shall have matured into an Event of Default and, unless and until
such event shall have so matured into an Event of Default or such event has been
cured or shall otherwise cease to exist, the Beneficiary (or the Depository)
shall not release any such insurance proceeds or Award and the same shall be
held until an Event

of Default occurs or the Default has been cured or shall otherwise cease to
exist.

     2.5.7. Any such insurance proceeds (other than the proceeds of the rent
insurance policy, which shall be paid as provided in SECTION 2.5.8 below) or
Award which are to be applied to restoration, replacement or rebuilding of the
Mortgaged Premises shall, after payment or reimbursement to the Beneficiary of
all reasonable costs and expenses of the Beneficiary in collecting such proceeds
or Award, be applied upon satisfaction of the following provisions and
conditions:

          (a) If the damage be of such nature as to require the Trustor to
     construct a replacement for, or to alter in any material or substantial
     way, the damaged or destroyed items, the Trustor shall, before commencing
     any such work, submit copies of the plans and specifications therefor to
     the Beneficiary for the Beneficiary's approval, such approval to not be
     unreasonably withheld or delayed.

          (b) If after payment or reimbursement to the Beneficiary of all costs
     and expenses of the Beneficiary in collecting such insurance proceeds or
     Award, the aggregate insurance proceeds or Award received by reason of any
     single instance of such damage or destruction or condemnation, as the case
     may be, shall be $200,000 or less such insurance proceeds or Award shall be
     paid to the Trustor, which shall hold all amounts so received in trust for
     application first to pay the entire cost of restoring, repairing,
     rebuilding or replacing the damaged or destroyed items, before any portion
     of such proceeds may be used or applied for any other purpose. If the
     aggregate net insurance proceeds or Award by reason of any single instance
     of such damage or destruction or condemnation, as the case may be, shall be
     more than $200,000 such sums shall be held and disbursed by Fleet Bank,
     National Association or, if this Trust Deed is held by another financial
     institution, by such financial institution or, if this Trust Deed is not
     held by a financial institution, by a financial institution selected by the
     then Beneficiary (the holder of such monies, the "Depository") in
     accordance with the following provisions of this SECTION 2.5.7.

          (c) The Beneficiary shall have received as to each such disbursement a
     certificate of the Trustor (i) requesting the payment of a specified

                                     - 18 -

     amount of such insurance or condemnation proceeds; (ii) describing in
     reasonable detail the work and materials applied to the restoration,
     replacement or rebuilding of the damaged, destroyed or taken Improvement,
     or Building Service Equipment and/or Furnishings located therein, since the
     date of the last such certificate; (iii) stating that the requested amount
     does not exceed the cost of such work and materials; and (iv) stating that
     a request for payment for such work and materials has not previously been
     made, accompanied by:

               1. a certificate of an independent engineer or architect
          designated by the Trustor, who shall have been approved in writing by
          the Beneficiary (such approval not to be unreasonably withheld),
          stating (i) that the work and materials described in the accompanying
          certificate of the Trustor were satisfactorily performed and furnished
          and were necessary, appropriate or desirable to the restoration,
          replacement or rebuilding of the damaged, destroyed or taken
          Improvement, or Building Service Equipment and/or Furnishings; (ii)
          that the amount specified in such certificate of the Trustor does not
          exceed the reasonable cost of such work and materials; and (iii) the
          additional amount, if any, required to complete the restoration,
          replacement or rebuilding of the damaged, destroyed or taken
          Improvement, Building Service Equipment and/or Furnishings; and

               2. evidence reasonably satisfactory to the Beneficiary (i) that
          there exists no filed or recorded lien, or lien notice, or encumbrance
          or charge in respect of all or any part of the Mortgaged Premises that
          is prior to or on a parity with the lien of this Trust Deed, except as
          may be permitted in the Permitted Encumbrances; (ii) that neither the
          Mortgaged Premises nor any part thereof is subject to any recorded or
          filed mechanic's, laborer's, materialman's or any similar lien,
          encumbrance or charge; and (iii) that none of the Building Service
          Equipment and Furnishings provided in connection with such
          restoration, replacement or rebuilding is subject to any security
          interest other than in favor of the Beneficiary;

     Upon satisfaction of the conditions set forth herein, the Beneficiary shall
pay to the Trustor the amount of such insurance or condemnation proceeds
requested in such certificate of the Trustor or consent to the Depository's
payment thereof, as the case may be; provided, however, that in no event shall
the balance of insurance or condemnation proceeds held by the Beneficiary and
the Depository be reduced below the amount specified in such certificate of the
independent engineer or architect as the amount required to complete the
restoration, replacement or rebuilding of the damaged, destroyed or taken
Improvement, Building Service Equipment and/or Furnishings. Each such payment,
whether made by the Beneficiary or the Depository, shall be held by the Trustor
in trust and shall be used solely for the payment of the cost of the work and
materials described in the certificate of the Trustor, or if such cost or any
part thereof has theretofore been paid by the Trustor out of its own funds, then
for the reimbursement to the Trustor of any such cost or part thereof paid by
it. Any balance of insurance or condemnation proceeds held by the Beneficiary
after the completion of the restoration, replacement or rebuilding and payment
of all costs incurred in connection therewith, to be evidenced by a certificate
to such effect of such independent engineer or architect delivered to the
Beneficiary, shall, if no Event of Default shall have occurred and be
continuing, be released to the Person lawfully entitled thereto. Notwithstanding
the foregoing, if the Trustor needs to make deposits with or payments to
contractors prior to the work being performed, if the Beneficiary is otherwise
obligated to allow funds to be used to rebuild or restore, the Beneficiary
agrees that it will not unreasonably withhold or delay its consent to the
Trustor's request that such deposits or advances payments be allowed.

     2.5.8. All proceeds of rent insurance payable as a result of the occurrence
of any fire or other casualty which affects the Mortgaged Premises, or any part
thereof, shall be paid to the Beneficiary or, if the Beneficiary is not a
financial institution, the Depository. The Beneficiary or the Depository, as the
case may be, if it shall receive such proceeds, shall hold such proceeds in
trust if permitted under law, and in an account bearing interest (payable to or
for account of the Trustor), and shall apply or cause such proceeds (including
any net interest thereon) to be applied to the payment of those items referred
to in SECTION 2.5.1(f) which become, and as they become, due and payable from
and after the date of the occurrence of such damage or loss, until the
completion of the necessary restoration or replacement by the Trustor or 

                                     - 20 -

until the exhaustion of such proceeds (including any interest thereon),
whichever first occurs. Upon completion of such restoration or replacement, any
balance of such rent insurance proceeds, together with the interest thereon, if
any, not theretofore applied as provided herein, in the hands of the Beneficiary
or the Depository, as the case may be, shall, provided that no Event of Default
shall have occurred and be continuing, be paid to the Person lawfully entitled
thereto.

     2.5.9. Nothing in this SECTION 2.5 contained shall (i) relieve the Trustor
of its duty to repair, restore, rebuild or replace the Improvements, Building
Service Equipment and/or Furnishings following damage or destruction by fire or
other casualty or taking in the event that no Award or an inadequate Award or
that no or inadequate proceeds of insurance are available to defray the cost of
such repairing, restoring, rebuilding or replacement (provided, however, the
Trustor shall be permitted to receive the insurance proceeds upon satisfaction
of the conditions set forth herein provided, in addition, that all of the
Insurance or Award Conditions have been and remain satisfied), or (ii) relieve
the Trustor of its obligation to pay principal and interest and to make all
other payments required by the Note, the Loan Agreement and this Trust Deed
subsequent to the occurrence of any fire or other casualty, or taking, except
if, and to the extent that, any proceeds of rent insurance are applied by the
Beneficiary in accordance with SECTION 2.5.8 to such required payments.

     2.5.10. If, while any insurance proceeds or Award is being held by the
Beneficiary or the Depository, an Event of Default shall occur and be
continuing, the Beneficiary shall be entitled to receive and apply all such
insurance proceeds or Award in reduction of the indebtedness and other
obligations secured by this Trust Deed, in such order and respective amounts, as
the Beneficiary in its discretion shall determine.

     2.6. To Comply with Laws.

     2.6.1. The Trustor, at its own expense, will promptly cure all violations
of law affecting the Mortgaged Premises, or any part thereof, and/or the use and
operation thereof and will promptly comply, or cause to be complied with, all
present and future Legal Requirements. However, the Trustor shall have the
right, after prior notice to the Beneficiary, to contest by appropriate legal
proceedings, diligently conducted in good faith, the validity or application of
any Legal Requirement if and so

long as the Trustor shall promptly furnish to the Beneficiary a certificate to
such effect showing the steps taken to comply with such provisions, provided
that:

          (a) if by the terms of any such Legal Requirement, compliance
     therewith pending the prosecution of any such proceeding may be delayed
     legally without incurring any lien, charge or liability of any kind against
     the Mortgaged Premises, or any part thereof, and without subjecting the
     Trustor or the Beneficiary to any liability, civil or criminal, for failure
     so to comply therewith, the Trustor may delay compliance therewith until
     the final determination of any such proceeding; and

          (b) if any lien, charge or civil liability would be incurred by reason
     of any such delay, the Trustor nevertheless, on the prior written consent
     of the Beneficiary, such consent not to be unreasonably withheld, may
     contest and delay compliance with the Legal Requirement, provided that such
     delay would not subject the Beneficiary to criminal liability and the
     Trustor (i) furnishes to the Beneficiary security reasonably satisfactory
     to the Beneficiary against loss or injury by reason of such contest or
     delay and (ii) prosecutes the contest with due diligence.

     2.6.2. Notwithstanding the provisions of SECTION 2.6.1, if any delay in
compliance with any Legal Requirement shall, in the reasonable judgment of the
Beneficiary, place all or any part of the Mortgaged Premises in imminent danger
of being forfeited or lost, the Trustor shall, upon written notice from the
Beneficiary, immediately comply with such Legal Requirement.

     2.6.3. The Trustor will use and permit the use of the Mortgaged Premises
only in accordance with the material requirements of any applicable licenses and
permits issued by Governmental Authorities.

     2.6.4. The Trustor will procure, pay for and maintain (or cause to be
procured, paid and maintained) all permits, licenses and other authorizations
required to be procured and maintained by the owners and operators of the
Mortgaged Premises for any then use of all or any part of the Mortgaged Premises
then being made and for the lawful and proper operation and maintenance thereof.

     2.7. Limitation on Alterations and Demolition.

     2.7.1. The Trustor shall not voluntarily demolish, replace or alter the
Mortgaged Premises, or any part thereof, or voluntarily make any addition
thereto, or voluntarily construct any additional improvements thereon, or suffer
any of the same to occur, whether structural or otherwise (collectively,
"change"), without the prior written consent of the Beneficiary, which consent
shall not be unreasonably withheld or delayed; provided, however, that if no
Event of Default is continuing and such change involves an estimated cost of
less than $100,000 and is non-structural or if no Event of Default is continuing
and such change is non-structural and is being made to prepare space for a Space
Tenant pursuant to a Space Lease entered into in accordance with the Loan
Agreement, then, in either of such events, the Beneficiary's consent shall not
be required; provided, further, however, that if any such change is required by
law, the Trustor may make such change with the prior written consent of the
Beneficiary, which consent the Beneficiary will not unreasonably withhold or
delay. As a condition to any consent under this SECTION 2.7.1, the Beneficiary
may require (a) that plans and specifications for the proposed work, prepared by
a reputable architect reasonably satisfactory to the Beneficiary, be submitted
to the Beneficiary for approval, and (b) that the Trustor obtain a payment and
performance bond or other security reasonably satisfactory to the Beneficiary in
form and amount reasonably satisfactory to the Beneficiary from the contractor
or subcontractor performing the work unless such work amounts to less than
$200,000 in aggregate total cost. All work performed by or on behalf of the
Trustor shall be completed with all reasonable diligence and continuity, in a
good and workmanlike manner, and in compliance with all applicable Legal
Requirements. Unless, and to the extent that, the provisions of SECTION 2.7.2 be
applicable, no Building Service Equipment or Furnishings shall be removed from
the Mortgaged Premises during the course of any such work without prior
notification to the Beneficiary and unless provision is made for return or
replacement on or prior to the completion of the work. The provisions of this
SECTION 2.7.1. shall apply to any change made or required to be made by the
Trustor in the course of complying with any other of the provisions of this
Trust Deed. A duplicate set of all plans and specifications required to be filed
with any Governmental Authority prior to, or at any time in connection with, any
such alteration, demolition or new construction shall be furnished to the
Beneficiary. The Trustor will pay on demand the reasonable expenses incurred

                                     - 23 -

by the Beneficiary in the review of plans and specifications provided for in
this Trust Deed.

     2.7.2. The Trustor shall have the right, at any time and from time to time,
to remove and dispose of any item of Building Service Equipment or Furnishings
which may have become obsolete or unfit for use or which is no longer useful in
the operation of the Improvements, provided that the Trustor promptly replaces
such item with other Building Service Equipment or Furnishings, free of superior
title, liens or claims (other than in favor of the Beneficiary) unless consent
of the Beneficiary is first obtained, not necessarily of the same character but
of at least equal quality, value and usefulness in connection with the operation
and maintenance of the Mortgaged Premises, provided, further, however, no
removal of any item of Building Service Equipment or Furnishings then having a
fair market value of $50,000 or more shall be made without the prior written
consent of the Beneficiary, which consent will not be unreasonably withheld or
delayed. However, if by reason of technological or other developments in the
operation and maintenance of buildings and other improvements of the general
character of the Improvements or a change in the use of the Mortgaged Premises
or any part thereof, no replacement of the Building Service Equipment or
Furnishings so removed would be necessary or desirable for the proper operation
or maintenance of the Improvements, the Trustor shall not be required to replace
the item so removed.

     2.8. Limitation on Disposition of the Mortgaged Premises.

     2.8.1. Except as expressly set forth in this Trust Deed or the Loan
Agreement (including, without limitation, SECTIONS 5.01 and 6.21 of the Loan
Agreement), the Trustor shall not directly or indirectly sell, assign, mortgage,
alienate, pledge or otherwise transfer or further encumber the Mortgaged
Premises or any part thereof or any interest therein or in any of the rents,
profits or income generated thereby, whether voluntarily, involuntarily, by
operation of law or otherwise, or lease all or any portion thereof or an
undivided interest therein, without the prior written consent of the
Beneficiary. The foregoing events are hereinafter referred as a "Transfer". Any
transfer without prior written the consent of the Beneficiary is an Event of
Default.

     2.8.2. If there shall be a violation of the terms and provisions of SECTION
2.8.1, whether by the

                                     - 24 -

Trustor or any other person, in addition to all other rights and remedies
available to the Beneficiary under this Trust Deed, the Beneficiary shall have
the option, by the giving of notice to the Trustor, of declaring the entire
unpaid principal balance of the Note, together with all accrued and unpaid
interest and all other sums and charges evidenced thereby or payable pursuant to
the Loan Agreement, immediately due and payable.

     2.9. Maintenance of Mortgaged Premises; Covenant Against Waste; Inspection
by the Beneficiary. The Trustor will not commit or permit waste on the Mortgaged
Premises and, at its expense, will keep and maintain the Improvements, the
Building Service Equipment and Furnishings in its (or their) present state of
repair and condition, reasonable wear and tear excepted, and, if improved, in
such improved state of repair and condition, reasonable wear and tear excepted;
provided, that this shall not limit the Trustor's other obligations hereunder,
such as compliance with laws. The Trustor shall do or cause to be done all
maintenance and make or cause to be made all repairs as may be required by the
landlord under any Space Lease. The Trustor will neither do nor permit to be
done anything to the Mortgaged Premises that may materially impair the value
thereof or which may violate any covenant, condition or restriction affecting
the Mortgaged Premises, or any part thereof, or which would effect any material
change therein or in the condition thereof that would increase the danger of
fire or other hazard arising out of the operation of the Mortgaged Premises.
Subject to the rights of Space Tenants, the Beneficiary, and its representatives
and agents, may enter and inspect the Mortgaged Premises at any time after
reasonable notice (which may be oral) during usual business hours, and the
Trustor shall, within thirty (30) days after demand by the Beneficiary (or
immediately upon demand in case of emergency), make such repairs, replacements,
renewals or additions, or perform such items of maintenance, to the Mortgaged
Premises as the Beneficiary may reasonably require in order to cause the
Mortgaged Premises to comply with the standards established in this SECTION 2.9.

     2.10. To Furnish Certificates; Other Reporting Requirements.

     2.10.1. The Trustor will, at its own expense, deliver to the Beneficiary,
within fifteen (15) days after written request, but no more frequently than once
per six (6) month period, a written statement executed by the Trustor, in
recordable form, setting forth to the best of the Trustor's knowledge, the
amount then unpaid upon the

Note and secured by this Trust Deed and stating whether any offsets or defenses
exist against the indebtedness secured hereby; and, if any such offsets or
defenses are alleged to exist, then the factual basis and amount of such claimed
offsets or defenses.

     2.10.2. The Trustor will, if requested by the Beneficiary, deliver to the
Beneficiary a certificate of an officer of the general partner of the Trustor or
of such general partner's general partner, to the effect that he is familiar
with this Trust Deed and the other Security Documents, has reviewed the affairs
of the Trustor, and to the best of his knowledge and belief there exists no
Event of Default and no act or event has occurred or exists which with notice or
lapse of time or both could become such an Event of Default, or if any such
event or Event of Default exists, specifying it and what action the Trustor is
taking to cause it to be remedied.

     2.11. After-Acquired Property. All right, title and interest of the Trustor
in and to all improvements, betterments, renewals, substitutes and replacements
of, and all additions and appurtenances to, the Mortgaged Premises hereafter
acquired, constructed, assembled or placed on the Mortgaged Premises,
immediately upon such acquisition, construction, assembly or placement, as the
case may be, and in each such case without any further mortgage, conveyance or
assignment or other act of the Trustor, shall become subject to the lien of this
Trust Deed as fully and completely, and with the same effect, as though now
owned by the Trustor and specifically described in the granting clauses hereof;
and at any time and from time to time the Trustor, on demand, will execute,
acknowledge and deliver to the Beneficiary any and all such further assurances,
mortgages, conveyances or assignments as the Beneficiary may reasonably require
to further evidence, confirm and perfect the provisions of this SECTION 2.11.

     2.12. Further Assurances. The Trustor shall, at its sole cost and without
expense to the Beneficiary, on demand, do, execute, acknowledge and deliver all
and every such further acts, deeds, conveyances, mortgages, assignments, notices
of assignment, transfers and assurances as the Beneficiary shall from time to
time reasonably require for better assuring, conveying, assigning, transferring
and confirming unto the Beneficiary the property and rights hereby mortgaged or
assigned or intended now or hereafter so to be, or which the Trustor may be or
may hereafter become bound to convey, mortgage or assign to the Beneficiary, or
for carrying out the intention or facilitating the

performance of the terms of this Trust Deed, or for filing, registering or
recording this Trust Deed.

     2.13. Recorded Instruments. The Trustor will promptly perform and observe,
or cause to be performed and observed, all of the terms, covenants and
conditions of all instruments of record affecting the Mortgaged Premises (other
than non-consensual encumbrances hereafter affecting the Mortgaged Premises, the
validity or enforceability of which the Trustor is contesting in accordance with
this Trust Deed) where non-compliance therewith affects the security of this
Trust Deed or imposes any duty or obligation upon the Trustor or any Space
Tenant. The Trustor shall do or cause to be done all things reasonably required
to preserve intact and unimpaired and to renew any and all rights-of-way,
easements, grants, appurtenances, privileges, licenses, franchises and other
interests and rights in favor of or constituting any portion of the Mortgaged
Premises. The Trustor will not, without the prior written consent of the
Beneficiary, which consent shall not be unreasonably withheld or delayed,
initiate, join in or consent to any private restrictive covenant or other public
or private restriction as to the use of all or any portion of the Mortgaged
Premises. The Trustor will, however, comply with all lawful restrictive
covenants and zoning ordinances and other public or private restrictions
affecting all or any portion of the Mortgaged Premises.


                                  ARTICLE III.

                                  Condemnation


     3.1. Notice of Taking. The Trustor shall promptly notify the Beneficiary if
the Trustor receives notice of the institution of any proceeding or negotiations
for the taking of the Mortgaged Premises, or any part thereof, whether for
permanent or temporary use and occupancy in condemnation or by the exercise of
the power of eminent domain or by agreement of interested parties in lieu of
such condemnation (all the foregoing called a "taking"); shall keep the
Beneficiary currently advised, in detail, as to the status of such proceedings
or negotiations and will promptly give to the Beneficiary copies of all notices,
pleadings, judgments, determinations and other papers received or delivered by
the Trustor in connection with any such proceedings. The Beneficiary shall have
the right to appear and participate in such proceedings and may be represented
by counsel. The Trustor will not, without the

                                     - 27 -

Beneficiary's prior written consent, which consent shall not be unreasonably
withheld or delayed, enter into any agreement for the taking of the Mortgaged
Premises, or any part thereof, with anyone authorized to acquire the Mortgaged
Premises by eminent domain or in condemnation.

     3.2. Condemnation Award. If the Mortgaged Premises shall be the subject of
a taking the Beneficiary shall be entitled to and shall receive the total of
such portion of all awards made that shall be allowed to the Trustor with
respect to all the right, title and interest of the Trustor in and to the
Mortgaged Premises (the award made in any total, partial or temporary taking is
herein called the "Award"), provided that the obligations of the Trustor to
perform the terms, covenants and conditions of this Trust Deed, if any, affected
by such taking shall continue unimpaired until the actual vesting of title in
such proceeding and the actual receipt by the Beneficiary of the Trustor's share
of the entire Award resulting from such taking.

     3.3. Application of Award. The Beneficiary shall have the option of
treating a total taking or a substantial taking (as hereinafter defined) as an
Event of Default and of accelerating the entire indebtedness secured hereby, in
which event it shall apply the Trustor's entire Award in reduction of such
indebtedness (including principal, interest and other sums secured hereby, in
such order as the Beneficiary may determine) and shall turn over any balance
remaining, if any, to the Person lawfully entitled thereto; or if the
Beneficiary shall not so elect to accelerate the indebtedness and apply the
Award thereto, then the total Award shall, regardless of amount, be deposited
with the Beneficiary or with the Depository, the Trustor hereby agreeing to
elect that such proceeds be held and disbursed by the Depository in accordance
with SECTIONS 2.5.6, 2.5.7, 2.5.8, 2.5.9 and 2.5.10 hereof for restoration
required to be made by the Trustor. If there be a partial taking, the net
proceeds of the Award shall be deposited with the Beneficiary and applied by the
Beneficiary in accordance with the provisions of SECTIONS 2.5.6, 2.5.7, 2.5.9
and 2.5.10. Any Award remaining after the completion of such restoration,
replacement or rebuilding shall be applied in reduction of the indebtedness
(including principal, interest and other sums secured hereby) in such order as
the Beneficiary shall determine. A partial taking is substantial only if it
materially decreases the fair market value of the Mortgaged Premises and the
remainder of the Mortgaged Premises cannot be restored to an economically viable
whole.

     3.4. Temporary Taking. If any Award payable to the Trustor on account of a
taking for temporary use or occupancy is made in a lump sum or is payable other
than in equal monthly installments, the Trustor shall pay over such Award to the
Depository and such Award shall be applied to installments of Impositions and of
principal and interest and all other charges secured by this Trust Deed or due
under the Note, the Loan Agreement, or the other Security Documents as and when
the same become due and payable. Any unapplied portion of such Award held by the
Depository when such taking ceases or expires (if no Event of Default has then
occurred and is continuing), or after the indebtedness secured by this Trust
Deed or due under the Loan and Security Documents shall have been paid in full,
shall be paid to the Person lawfully entitled thereto.

     3.5. The Trustor's Obligation to Restore. If all available proceeds of the
Award are made available to the Trustor for restoration, replacement or
rebuilding pursuant hereto, the Trustor shall be obligated promptly to restore,
replace, rebuild or alter any Improvements or Building Service Equipment
affected by a taking so as to restore the Mortgaged Premises to an economically
viable whole, all without regard to the adequacy of the proceeds of an Award, if
any, made available to the Trustor.


                                   ARTICLE IV.

                   Assignment of Space Leases, Rents, Profits
                   and Other Income as Further Security, Etc.


     4.1. Assignment of Space Leases, Rents, Issues and Profits. Subject to the
Trustor's rights herein, including those set forth in SECTION 4.3.2 below, the
Trustor hereby absolutely, presently and irrevocably transfers, assigns and sets
over unto the Beneficiary all right, title and interest of the Trustor in and to
all Space Leases, if any, now or hereafter entered into with respect to all or
any part of the Mortgaged Premises, and all renewals, extensions, subleases or
assignments thereof, and all other occupancy agreements (written or oral), by
concession, license or otherwise, together with all of the rents, income,
receipts, revenues, issues and profits arising therefrom (the "Collateral").

     4.2. The Trustor's Covenants Regarding Space Leases.

     4.2.1. Without the prior consent and approval of the Beneficiary in each
instance, the Trustor will not (a) assign, pledge, hypothecate or otherwise
encumber any of the Space Leases or the rents, income, issue and profits of the
Mortgaged Premises; or (b) enter into any Space Leases affecting the Mortgaged
Premises or any part thereof, unless such Space Lease is expressly subordinate
to the lien of this Trust Deed and to any consolidation, extension, renewal,
recasting or refinancing hereof and the Space Lease provides, in substance, that
in the event of enforcement by the Beneficiary of the remedies provided for by
law or by this Trust Deed, each Space Tenant shall, at the option of the
Beneficiary, enter into a agreement with the Beneficiary which shall provide,
among other things, that (i) such Space Tenant shall attorn to any person
succeeding to the interest of the Trustor as a result of such enforcement and
shall recognize such successor in interest as landlord under such Space Lease
without change in the terms or other provisions thereof, (ii) such successor
shall not be bound by any payment of rent or additional rent for more than one
(1) month in advance or any amendment or modification of any such Space Lease
made without the Beneficiary's written consent, and (iii) such successor shall
not disturb the possession of the Space Tenant provided certain conditions (as
determined by the Beneficiary) have been satisfied, including, without
limitation, that the Space Tenant shall not be in default under the terms of the
Space Lease; or (c) enter into any Space Leases without the prior written
consent of the Beneficiary unless permitted in SECTION 6.21 of the Loan
Agreement.

     4.2.2. The Trustor further represents, warrants, covenants and agrees that:

          (a) To the best of its knowledge, each Space Lease is (or, when
     executed, will be) a valid and legally enforceable obligation of the
     parties thereto, in full force and effect.

          (b) With respect to each Space Lease and the Space Tenant security
     deposits thereunder, any and/or all of such security deposits shall be held
     as required by the Space Lease but in no event in a manner other than that
     required by law.

          (c) The Trustor shall, at its sole cost and expense, keep, observe,
     perform and discharge, duly and punctually, all and singular the material
     obligations, terms, covenants, conditions, representations and warranties
     of each Space Lease on the part of the Trustor to be kept, observed,
     performed and discharged.

          (d) (i) Except as herein in this clause (i) expressly provided, the
     Trustor shall, at its sole cost and expense, maintain the Space Leases in
     full force and effect; the Trustor will not waive its rights under or
     materially modify, change, supplement, alter or amend ("Change"), nor shall
     the Trustor surrender (whether partial or total), terminate, cancel or
     subordinate, any of the Space Leases or enter into any Backlease (whether
     through an Affiliate or otherwise), and any such attempted Change,
     surrender, termination, cancellation or subordination or Backlease shall be
     void, unless, in each case, the prior written consent thereto of the
     Beneficiary shall have been obtained. Notwithstanding the foregoing, the
     Trustor may (x) terminate any Space Lease under 10,000 rentable square feet
     as a result of a default by the tenant under such Space Lease and (y)
     consent to any sublease or assignment of any Space Lease under 10,000
     rentable square feet provided (aa) such termination is being effected in
     the ordinary course of the Trustor's business, (bb) no Event of Default
     then exists and no event has occurred that with the passage of time or the
     giving of notice or both would constitute an Event of Default, and (cc) the
     Beneficiary determines, in its reasonable discretion, that upon the
     effectiveness of such termination, assignment or sublease (i) the Loan to
     Value Ratio (as defined in the Loan Agreement, and taking into
     consideration the value of all of the Projects, as defined in the Loan
     Agreement) is not greater than 55%, and (ii) the Debt Service Coverage
     Ratio (as defined in the Loan Agreement, and taking into consideration the
     loss of income resulting from such termination, assignment or sublease, as
     projected by the Beneficiary in its reasonable discretion) is not less than
     1.40:1.0. A material Change shall include but not be limited to any
     material Change in the amount or time of payment of the rent or additional
     rent, the length of term or square footage of the premises under any Space
     Lease or any other Change which would materially adversely affect the
     Trustor's rights under the Space Lease, or would affect the Beneficiary's

                                     - 31 -

     rights under the Space Lease or the value of the Space Lease as collateral
     security for the indebtedness.

               (ii) The Trustor shall, at its sole cost and expense, enforce the
          Space Leases in accordance with their terms; and shall appear in and
          defend any action or proceeding arising to which it is a party under
          or in any manner connected with any of the Space Leases.

          (e) The Trustor shall deliver to the Beneficiary a copy of each notice
     of default sent or received by it relating in any way to any Space Lease
     promptly upon, but in any event within five (5) business days after, its
     sending or receipt thereof.

     4.3. The Trustor's Rights and Powers.

     4.3.1. The Trustor hereby irrevocably, in the name of the Trustor or
otherwise, authorizes and empowers the Beneficiary, and assigns and transfers
unto the Beneficiary, and constitutes and appoints the Beneficiary its true and
lawful attorney-in-fact, coupled with an interest and as its agent, irrevocably,
with full power or substitution for it and in its name, but solely for the
following purposes: (i) to exercise and enforce every right, power, remedy,
authority, option and privilege of the Trustor under the Space Leases, and as
such attorney-in-fact, the Beneficiary may subordinate, terminate, cancel or
modify the Space Leases, accept the surrender of the Space Leases, give any
notice, take any action resulting in such subordination, termination,
cancellation, modification or surrender, give any authorization, furnish any
information, make any demands, execute any instruments and take any and all
other action on behalf of and in the name of the Trustor which in the opinion of
the Beneficiary may be necessary or appropriate to be given, furnished, made,
exercised or taken by the Trustor under the Space Leases in order to comply
therewith, to perform the conditions thereof or to prevent or remedy any default
by the Trustor thereunder or to enforce any of the Trustor's rights and remedies
thereunder, and (ii) to ask, require, demand, receive and collect and give
acquittances for the Income (as hereinafter defined), and on nonpayment thereof
to sue for, recover and receive the same, and on payment thereof to give
sufficient releases, receipts, discharges and acquittances thereof; to endorse
any checks or other instruments or orders in connection therewith and to file
any claims or take any action or institute any proceedings which the Beneficiary
may deem to

                                     - 32 -

be necessary or advisable; provided, however, that the power provided for in
this sentence may not be exercised by the Beneficiary unless an Event of Default
shall have occurred and be continuing. "Income" shall mean all deposits, rents,
issues, profits, revenues, royalties, and other revenue producing arrangements,
whether written or oral, and all monetary benefits of, and/or derived from,
and/or sums payable under and by virtue of the Space Leases and/or the Premises.

     4.3.2. So long as there shall not have occurred and then be continuing any
Event of Default and until such right of the Trustor is terminated by the
Beneficiary as provided in SECTION 4.3.3, the Beneficiary will not exercise its
rights pursuant to SECTION 4.3.1, and, notwithstanding anything in SECTION 4.3.1
to the contrary, the Trustor shall have the right (but limited as hereinafter
provided) to exercise all of its rights under the Space Leases, including,
without limitation, to collect and receive all rents, income, receipts,
revenues, issues and profits arising therefrom, provided that the Trustor shall
at all times comply with, observe and perform, in the exercise of such right,
all of the provisions of this Trust Deed and the other Security Documents
applicable to the Space Leases; provided, further, that no action shall be taken
or failed to be taken by the Trustor which would impair the Collateral or any
other collateral security for the Obligations provided for in the Security
Documents.

     4.3.3. The Beneficiary, upon the occurrence and during the continuance of
an Event of Default, at its option and upon written notice to the Trustor, shall
have the right to terminate the right of the Trustor to exercise its rights
under the Space Leases, and, thereupon, in addition, the Beneficiary, at any
time thereafter, at its option, shall have the complete right, power and
authority hereunder to exercise and enforce all rights, powers, remedies,
authority, options and privileges of the Trustor under the Space Leases in the
name of the Trustor or the Beneficiary, to enforce all obligations of the other
parties to the Space Leases and to exercise and enforce all of its rights and
remedies hereunder and under law not exercisable prior to an Event of Default.

     4.3.4. The Trustor does hereby direct each and all of the Space Tenants
under the Space Leases and all contractual obligors of the Trustor to pay any
Income to the Beneficiary upon written demand for payment thereof by the
Beneficiary without further inquiry. It is understood and agreed, however, that
no such demand shall be made unless an

Event of Default shall have occurred and be continuing. No such Space Tenant or
obligor shall be obliged to account to the Trustor for any amounts paid to the
Beneficiary by reason of any payment made to the Beneficiary pursuant to such
demand and, upon any such payment to the Beneficiary, shall be pro tanto
released from their obligations to the Trustor with respect to such payment.
Each Space Tenant shall be permitted to rely on any communication from the
Beneficiary pursuant hereto, and under no circumstances shall such Space Tenant
be obligated to the Trustor for any payments made to the Beneficiary hereunder.
Until such demand is made, the Trustor is authorized to collect or enforce or
continue collecting or enforcing such Income in accordance with the provisions
of this Trust Deed.

     4.3.5. The Beneficiary shall not have any duty as to the collection or
protection of the Collateral or any income thereon or payments with respect
thereto, or as to the preservation of any rights pertaining thereto beyond the
safe custody of any thereof actually in its possession. In no instance shall the
Beneficiary be responsible to lessees for payment of interest upon, or return
of, any lease security deposits, except as provided by law or as provided in the
leases and then only if and to the extent that such deposits are received by the
Beneficiary. The Trustor hereby waives notice of acceptance hereof, and except
as otherwise specifically provided herein or required by provision of law which
may not be waived, hereby waives any and all notices or demands with respect to
any exercise by the Beneficiary of any rights or powers which it may have or to
which it may be entitled with respect to the Collateral.

     4.3.6. The Trustor hereby irrevocably constitutes and appoints the
Beneficiary as the true and lawful attorney-in-fact of the Trustor, which
appointment is coupled with an interest, with full power of substitution, to
proceed from time to time in the Trustor's name in any statutory or
non-statutory proceeding affecting the Trustor or any Collateral, and the
Beneficiary or its nominee may (i) execute and file proof of claim for the full
amount of any Collateral and vote such claims for the full amount thereof (A)
for or against any proposal or resolution, (B) for a trustee or trustees or for
a receiver or receivers or for a committee of creditors and/or (C) for the
acceptance or rejection of any proposed arrangement, plan of reorganization,
composition or extension, and the Beneficiary or its nominee may receive any
payment or distribution and give acquittance therefor and may exchange or
release Collateral; (ii) endorse any draft or other

instrument for the payment of money, execute releases and negotiate and enter
into settlements; and (iii) execute all such other documents or instruments as
may be necessary or expedient to be executed by the Trustor for any of the
purposes of this Trust Deed; provided, however, that the power provided for in
this sentence may be exercised by the Beneficiary only while an Event of Default
is continuing. The Beneficiary shall have no duty to exercise any of the
aforesaid rights, privileges or options and shall not be responsible for any
failure to do so or delay in so doing.

     4.4. Remedies and Entry Upon Default.

     4.4.1. So long as no Event of Default shall have occurred and be
continuing, the Trustor shall have the right to collect (but not more than one
(1) month in advance) and retain all of the rents, gross receipts and other
payments, if any, from the Space Leases and from the Mortgaged Premises
generally, and the Beneficiary agrees that customary initial rent payments,
security deposits and reimbursements by a Space Tenant to the Trustor on account
of alterations made by the Trustor for the benefit of the Space Tenant are
permissible advance payments by the Space Tenant.

     4.4.2. Upon any Event of Default, the Beneficiary may, but shall not be
obligated to:

          (a) terminate the rights of the Trustor referred to in SECTION 4.3
     hereof and exercise all of the powers, rights and remedies provided for in
     SECTION 4.3 hereof, including those to be exercised only from and after an
     Event of Default;

          (b) at any time and from time to time, without notice to, or assent
     by, the Trustor or any other Person, but without affecting any of the
     Obligations, in the name of the Trustor or in the name of the Beneficiary,
     notify the account debtors and obligors on any or all of the Space Leases
     to make payment and performance directly to the Beneficiary, and demand,
     collect, receive, compound and give acquittance for the Space Leases or any
     part thereof; extend the time of payment and performance of, compromise or
     settle for cash, credit or otherwise, upon any terms and conditions, any of
     the Space Leases; endorse to the order of the Beneficiary checks, drafts or
     other orders or instruments for the payment of moneys payable to the
     Trustor which shall be issued in respect of any of the Space Leases; file
     any claims,

     commence, maintain or discontinue any actions, suits or other proceedings
     deemed by the Beneficiary necessary or advisable for the purpose of
     collecting upon or enforcing any of the Space Leases; and execute any
     instrument and do all other things deemed necessary and proper by the
     Beneficiary to protect and preserve and realize upon the Space Leases
     and/or the other rights contemplated hereby; the Trustor hereby irrevocably
     constitutes and appoints the Beneficiary as such the Trustor's lawful
     attorney-in-fact, coupled with an interest, and its agent for the foregoing
     purposes;

          (c) demand, collect, sue for, attach, levy, recover, receive,
     compromise and adjust, and make, execute and deliver receipts and releases
     for all Income that may then be or may thereafter become due, owing or
     payable with respect to the Premises or any part or parts thereof from any
     present or future lessees, tenants, subtenants or occupants thereof or from
     any present or future contract obligors; and/or

          (d) pay, in such order as the Beneficiary in its sole discretion shall
     determine, from and out of the Income collected in connection with the
     Premises and/or the Collateral or any part or parts thereof or from or out
     of any other funds (less the expense of collection, including reasonable
     attorneys' fees and disbursements), any taxes, assessments, water rates,
     sewer rates, or other government or other charges levied, assessed or
     imposed against the Premises or any part or part thereof, and also any and
     all other charges, costs and expenses which the Beneficiary deems necessary
     or advisable to pay in respect of the management or operation of the
     Premises, including, without limitation, the costs of insurance policies,
     repairs and alterations, commissions for renting the Premises or any part
     or parts thereof, legal expenses in enforcing claims, preparing papers or
     procuring any other services that may be required and any amounts payable
     under or pursuant to any Lease; all amounts so paid and expended shall be
     payable on demand, together with interest at the Involuntary Rate from the
     date incurred until paid, and be deemed to be included within the
     Obligations and secured by this Trust Deed; the provisions of this ARTICLE
     and the rights given to the Beneficiary hereby shall inure to the benefit
     of the Beneficiary even though the Beneficiary does not enter and take
     possession of the Premises; any balance remaining after the indebtedness
     secured hereby and the other obligations of the Trustor

     under the Loan and Security Documents shall have been paid in full shall be
     turned over to the Person lawfully entitled thereto. Neither the entry upon
     and taking possession of the Mortgaged Premises, nor the collection and
     application of the rents, gross receipts or other charges thereof, nor any
     other action taken by the Beneficiary in connection therewith, shall cure
     or waive any default hereunder or waive or modify any notice thereof or
     notice of acceleration of the Note theretofore given by the Beneficiary.

     4.4.3. If an Event of Default shall have occurred and be continuing, a
notice in writing by the Beneficiary to the Space Tenants under the Space Leases
advising them that the Trustor has defaulted hereunder and requesting that all
future payments of rent, additional rent or other charges under the Space Leases
be made to the Beneficiary (or its agent) shall be construed as conclusive
authority to such Space Tenants that such payments are to be made to the
Beneficiary (or its agent). Each Space Tenant shall be fully protected in making
such payments to the Beneficiary (or its agent) and be given full credit against
its obligations under the applicable Space Lease to the extent of payments made
to the Beneficiary (or its agent) pursuant to any such notice; and the Trustor
hereby irrevocably constitutes and appoints the Beneficiary the attorney-in-fact
and agent of the Trustor, coupled with an interest, for the purpose of endorsing
the consent of the Trustor on any such notice.

     4.5. No Obligation of Beneficiary.

     4.5.1. The Beneficiary shall not be obligated to perform or discharge any
obligation of the Trustor as a result of the assignment hereby effected, and the
Trustor hereby agrees to indemnify and hold the Beneficiary harmless from and
against any and all liability, loss or damage which the Beneficiary may incur by
reason of any act of the Beneficiary under this Trust Deed, other than as a
result of the Beneficiary's willful misconduct or gross negligence and other
than as a result of the Beneficiary's misconduct or negligence after the
Beneficiary has taken possession of the Premises. Should the Beneficiary (i)
incur any such liability, loss or damage by reason of this Trust Deed and which
is covered by the foregoing indemnity, or in defense against any such claims or
demands, or (ii) perform any acts or covenants on the part of the Trustor to be
performed under the Space Leases, or (iii) pay for the account of the Trustor
(other than from Income or from funds delivered to the Beneficiary by the
Trustor to be held in

trust for such purpose), any and all sums, costs and expenses for the discharge
of taxes, assessments, water rents or other liens against the Collateral or any
part thereof, or on account of insurance premiums or repairs, and also any
amounts and expenses necessary to perform any covenants and conditions to be
performed on the part of the Trustor under the Space Leases, the amount thereof,
including costs, expenses and reasonable attorneys' fees, together with interest
thereon at the Involuntary Rate from the date such expenses were paid by the
Beneficiary to the date of payment to the Beneficiary by the Trustor, shall be
included in the Obligations secured by this Trust Deed, and the Trustor shall
reimburse the Beneficiary therefor upon demand.

     4.5.2. The acceptance by the Beneficiary of this Trust Deed, with all the
rights, powers, privileges and authority so created, shall not at any time or in
any event obligate the Beneficiary to appear in or defend any action or
proceeding relating to the Collateral, or to take any action hereunder or
thereunder, or to expend any money or incur any expenses or perform or discharge
any obligation, duty or liability under the Collateral.


                                   ARTICLE V.

                Security Agreement Under Uniform Commercial Code

     5.1. This Trust Deed shall constitute a security agreement and a fixture
filing within the meaning of the Uniform Commercial Code of the State (the
"Code"), and the Beneficiary shall be deemed to be the "secured party" (as that
term is defined in the Code). The Trustor hereby grants to the Beneficiary, as
additional collateral for the obligations under the Note and the other
Obligations secured hereby, a security interest in and to all of the Mortgaged
Premises which are considered or as shall be determined to be personal property
or "fixtures" (as defined in the Code), including, without limitation, the
Building Service Equipment, the Furnishings, the Payments and Intangibles, all
books, records, licenses and certificates of the Trustor relating to the
Mortgaged Premises, together with all replacements thereof, substitutions
therefor or additions thereto (said property being sometimes hereinafter
referred to as the "Personal Property"). The Trustor agrees that a security
interest shall attach to the Personal Property for the benefit of the
Beneficiary to secure the indebtedness evidenced by the Note and the other
Obligations secured by this Trust Deed and all other sums and charges which may

                                     - 38 -

become due hereunder, thereunder or under any of the other Security Documents.
The Trustor hereby authorizes the Beneficiary to file financing and continuation
statements with respect to the Personal Property without the signature of the
Trustor, if permitted by the Code. In any event the Trustor covenants to execute
such financing and continuation statements as the Beneficiary may reasonably
request. If an Event of Default shall occur and be continuing, the Beneficiary,
pursuant to the appropriate provisions of the Code, shall have the option of
proceeding as to both real and personal property in accordance with its rights
and remedies in respect of real property under this Trust Deed and the law of
the State, in which event the default provisions of the Code shall not apply.
The Trustor agrees that, in the event the Beneficiary shall elect to proceed
with respect to the Personal Property separately from the real property, unless
a greater period shall then be mandated by the Code, five (5) days notice of the
sale of the Personal Property shall be reasonable notice. The expenses of
retaking, holding, preparing for sale and selling incurred by the Beneficiary
shall be assessed against the Trustor and shall include, but not be limited to,
the reasonable legal expenses incurred by Beneficiary. The Trustor agrees that
it will not remove or permit to be removed from the Mortgaged Premises any of
the Personal Property without the prior written consent of the Beneficiary
except as set forth in SECTION 2.7.2. All replacements, renewals and additions
to the Personal Property shall be and become immediately subject to the security
interest of this Trust Deed and the provisions of this ARTICLE V. The Trustor
warrants and represents that all Personal Property now is free and clear of all
liens, encumbrances or security interests other than the Permitted Encumbrances,
and that all replacements of the Personal Property, substitutions therefor or
additions thereto, unless the Beneficiary otherwise consents, will be, free and
clear of liens, encumbrances or security interests of others.

                         Events of Default and Remedies


     6.1. Events of Default. The whole of the outstanding Principal Amount (as

option of the Beneficiary, become due upon the happening of an Event of Default;
provided, however, that upon the

occurrence of a default specified in SECTIONS 5.01(f) or 5.01(g) of the Loan
Agreement, or upon the occurrence of any other default specified in any Loan
Document (as defined in the Loan Agreement) where provision is made for
acceleration to occur automatically as a consequence thereof, all sums owing to
the Beneficiary thereunder shall automatically become immediately due and
payable.

     6.2. Remedies. If an Event of Default shall occur and be continuing, the
Beneficiary, at its option, may:

     6.2.1. by notice to the Trustor, declare the entire principal amount of the
Note then outstanding and all accrued and unpaid interest thereon and all
obligations of the Trustor to the Beneficiary to be immediately due and payable,
and upon such declaration such principal and interest and all obligations of the
Trustor to the Beneficiary shall become and be immediately due and payable,
anything in the Note, the Loan Agreement or in this Trust Deed or in any of the
other Security Documents to the contrary notwithstanding;

     6.2.2. as a matter of right and without notice to the Trustor or anyone
claiming under the Trustor, and without regard to the then value of the
Mortgaged Premises or the interest of the Trustor therein, to apply to any court
having jurisdiction to appoint a receiver or receivers of the Mortgaged
Premises, and the Trustor hereby irrevocable consents to such appointment and
waives notice of any application therefor; any such receiver or receivers shall
have all the usual powers and duties of receivers in like or similar cases and
all the powers and duties of the Beneficiary in case of entry as provided in
this Trust Deed, and shall continue as such and exercise all such powers until
the later of (i) the date of confirmation of sale of the Mortgaged Premises,
(ii) the disbursement of all proceeds of the Mortgaged Premises collected by
such receiver and the payment of all expenses incurred in connection therewith,
and (iii) the termination of such receivership with the consent of the
Beneficiary or pursuant to an order by a court of competent jurisdiction;

     6.2.3. exercise any and all remedies available to a secured party under the
UCC in such order and in such manner as the Beneficiary in its sole discretion
may determine; provided, however, that the expenses of retaking, holding,
preparing for sale or the like, shall include reasonable attorneys' fees and
other expenses of the

     manner then permitted by law, upon such notice as may then be required by
     law; and

          (b) after deducting all costs, fees and expenses of the Trustee,
     including costs of evidence of title and attorneys' fees of the Trustee and
     the Beneficiary in connection with such sale, the Trustee shall apply, in
     the following priority, the proceeds of sale to payment of: (i) first, all
     sums expended under the terms hereof, not then repaid, with interest
     thereon at the Involuntary Rate, (ii) second, all other sums then secured
     hereby, in such order of priority and in such proportion as the Beneficiary
     in its sole discretion may elect, and (iii) the remainder, if any, to the
     Person lawfully entitled thereto.

     6.2.6. exercise any or all of its other rights and remedies provided
herein, in any of the Security Documents, or other document or agreement now or
hereafter securing all or any portion of the Obligations secured hereby, or as
provided by law, in such order of priority as the Beneficiary shall determine in
its sole discretion.

     6.3. Sale; No Marshalling of Assets.

     6.3.1. In case of a foreclosure sale, all of the Mortgaged Premises may be
sold in one parcel even though the proceeds of such sale exceed or may exceed
the indebtedness secured hereby. The Beneficiary shall not be required to
exercise any rights under this Trust Deed before proceeding against any other
security, shall not be required to proceed against other security before
proceeding under this Trust Deed, and shall not be precluded from proceeding
against any or all of any security held by the Beneficiary for any or all of the
indebtedness secured hereby in any order or at the same time.

     6.3.2. The Trustor agrees, to the full extent that it may lawfully do so,
that in any foreclosure or other action brought by the Beneficiary to enforce
this Trust Deed, it will not at any time insist upon or plead or in any way take
advantage of any appraisement, valuation, stay, marshalling of assets,
extension, redemption or moratorium law now or hereafter in force and effect so
as to prevent, hinder, delay or otherwise affect the enforcement of the
provisions of this Trust Deed or any rights or remedies the Beneficiary may have
hereunder or by law.

     6.3.3. If the Beneficiary shall elect to accelerate the indebtedness
secured hereby following the occurrence of an Event of Default, the Trustor,
within five (5) days after demand, will pay to the Beneficiary, or any receiver
appointed in connection with the foreclosure of this Trust Deed, any and all
amounts then held as security deposits under all Space Leases; and the
Beneficiary or such receiver shall be deemed to indemnify the Trustor against
all claims of tenants in respect of the security deposits so paid following such
demand.

     6.4. Legal Expenses of the Beneficiary.

     6.4.1. The Trustor will pay to the Beneficiary or the Trustee, as the case

proceeding to foreclose this Trust Deed or to recover or collect all, or any
portion of the indebtedness secured hereby; and (ii) in connection with any
modification or amendment or assignment of this Trust Deed or the other Security
Documents, together with interest on each such payment made by the Beneficiary
at the Involuntary Rate from the date of the Beneficiary's demand for such
payment to the date of reimbursement by the Trustor.

     6.4.2. If any action or proceeding be commenced in which the Beneficiary or
the Trustee is made a party, or in which it becomes necessary to defend or
uphold the lien of this Trust Deed, all reasonable sums paid by the Beneficiary
for the expense of any litigation to prosecute or defend the title, rights and
lien created by this Trust Deed (including, without limitation, reasonable
attorneys' fees) shall be paid by the Trustor, together with interest thereon at
the Involuntary Rate from the date of the Beneficiary's demand for such payment
to the date of reimbursement by the Trustor.

     6.5. Remedies Cumulative; No Waiver; Etc.

     6.5.1. No remedy in this Trust Deed conferred upon or reserved to the
Beneficiary is intended to be exclusive of any other remedy or remedies, and
each and every such remedy shall be cumulative, and shall be in addition to
every other remedy given hereunder or now or hereafter existing at law or in
equity. No delay or omission by the Beneficiary in exercising any right or power
arising upon any Event of Default shall impair any such right or power, or shall
be construed to be a waiver of or acquiescence in any such Event of Default; and
every power and remedy given by this Trust Deed to the Beneficiary may be
exercised from time to time as often as the Beneficiary may determine it is
appropriate to do so.

     6.5.2. A waiver in one or more instances of compliance with any of the
terms, covenants, conditions or provisions of the Note, the Loan Agreement or of
the Security Documents shall apply to the particular instance or instances and
at the particular time or times only, and no such waiver shall be deemed a
continuing waiver. In any event, no waiver shall be effective, or be asserted by
the Trustor as having been made, unless set forth in a writing signed by the
Beneficiary.

     6.5.3. The Trustor waives and renounces all homestead and similar exemption
rights with respect to the Mortgaged Premises provided for by the Constitution
and laws of the United States and of the State as against the collection of the
Security Documents, or any part thereof.

     6.6. No Merger. It is the intention of the parties to this Trust Deed that
if the Beneficiary or the Trustee shall at any time hereafter acquire title to
all or any portion of the Mortgaged Premises, then, and until the indebtedness
secured hereby has been paid in full, the interest of the Beneficiary hereunder
and the lien of this Trust Deed shall not merge or become merged in or with the
estate and interest of the Beneficiary or the Trustee as the holder and owner of
title to all or any portion of the Mortgaged Premises and that, until such
payment, the estate of the Beneficiary or the Trustee in the Mortgaged Premises
and the lien of this Trust Deed and the interest of the Beneficiary hereunder
shall continue in full force and effect to the same extent as if the Beneficiary
or the Trustee had not acquired title to all or any portion of the Mortgaged
Premises.

     7.1. Modifications. No change, amendment, termination, modification or
cancellation of this Trust Deed, or of any part hereof, shall be valid unless

accordance with the terms of the Security Documents, or to perform or observe
any other term, covenant, condition or obligation required to be performed or
observed by the Trustor under this Trust Deed or the other Security Documents,
without limiting any other provision of this Trust Deed, and without waiving or
releasing the Trustor from any obligation or default hereunder, after giving any
notice to the Trustor required hereunder and after the passage of any applicable
cure periods (or without such notice in the event of an emergency), the
Beneficiary (or any receiver of the Mortgaged Premises) shall have the right,
but not the obligation, to make any such payment, or to perform any other act or
take any appropriate action, including, without limitation, entry on the
Mortgaged Premises and performance of work thereat, as it, in its sole
discretion, may deem necessary to cause such other term, covenant, condition or
obligation to be promptly performed or observed on behalf of the Trustor or to
protect the security of this Trust Deed. All amounts advanced by, or on behalf
of, the Beneficiary in exercising its rights under this SECTION 7.3 (including,

Building Service Equipment and Furnishings. If any such lien shall be filed
against the Mortgaged Premises, or any part thereof, the Mortgagor promptly
shall discharge the lien of record, by bonding or otherwise. The Mortgagor shall
exhibit to the Mortgagee, upon request, appropriate receipts or other
satisfactory evidence of the payment of the Impositions or any other item which
may, if not paid, give rise to a lien against the Mortgaged Premises.

     2.4. To Pay Impositions.

     2.4.1. The Mortgagor will pay or cause to be paid, as and when due and
payable, all Impositions levied upon the Mortgaged Premises or any part thereof,
together with all filing, registration or recording fees and all expenses
incident to the execution and acknowledgement of this Mortgage, any mortgage
supplemental hereto, and will pay all federal, state, county and municipal stamp
taxes and other taxes, duties, imposts, assessments and charges arising out of
or in connection with the execution and delivery of the Note, this Mortgage, any
mortgage supplemental hereto, or any instrument of further assurance. However,
if by law, any Imposition may at the option of the taxpayer be paid in
installments (whether or not interest shall accrue on the unpaid balance
thereof), the Mortgagor shall have the right to exercise such option and to pay
such Imposition, or cause it to be paid (together with any accrued interest on
the unpaid balance) in installments as

they fall due and before any fine, penalty, further interest or cost may be
added thereto.

     2.4.2. If an Event of Default shall occur and be continuing, then upon
demand of the Mortgagee, the Mortgagor shall deposit with the Mortgagee a sum
which bears the same relation to the annual insurance premiums for all insurance
required by the terms hereof and real estate taxes and assessments assessed
against the Mortgaged Premises for the insurance period or tax year then in
effect, as the case may be, as the number of months elapsed as of the date of
such demand since the last preceding installment of said premiums or taxes or
assessments shall have become due and payable bears to twelve (12). For the
purpose of this computation, the month in which such last preceding installment
of premiums or real estate taxes or assessments became due and payable and the
month in which such demand is given shall be included and deemed to have
elapsed. On the first day of the month next succeeding the month in which such
demand is given, and thereafter on the first day of each and every month during
the term of this Mortgage, the Mortgagor shall deposit with the Mortgagee a sum
equal to one-twelfth of such insurance premiums and such taxes and assessments
for the then-current insurance period and tax year, so that as each installment
of such premiums and taxes and assessments shall become due and payable, the
Mortgagor shall have deposited with the Mortgagee a sum sufficient to pay the
same. All such deposits shall be received and held as part of such deposit by
the Mortgagee (all such deposits to be held in an account without interest
thereon) and shall be applied to the payment of each installment of such
premiums and taxes and assessments as they shall become due and payable. The
Mortgagee shall, upon demand, furnish evidence to the Mortgagor of the making of
each such payment. If the amount of such premiums and taxes and assessments has
not been definitely ascertained at the time when any such monthly deposits are
required to be made, the Mortgagor shall make such deposits based upon the
amount of such premiums and taxes and assessments for the preceding year,
subject to adjustment as and when the amount of such premiums and taxes and
assessments are ascertained. If at any time when any installment of such
premiums and such taxes and assessments becomes due and payable the Mortgagor
shall not have deposited a sum sufficient to pay the same, the Mortgagor shall,
within five (5) days after demand, deposit any deficiency with the Mortgagee.
Upon payment in full of the indebtedness secured by this Mortgage, any remaining
amount on deposit with the Mortgagee shall be repaid to the Person lawfully
entitled thereto. If an Event of Default shall occur and be continuing, the
Mortgagee may,

                                     - 10 -

at its option, apply all or any portion of the amounts then on deposit with the
Mortgagee pursuant to this SECTION 2.4.2 first to the payment of any premiums,
taxes or assessments then due, and any remaining amounts may be applied to the
payment of the indebtedness. The Mortgagor shall deliver to the Mortgagee all
insurance and tax bills promptly following receipt during any period when such
monthly deposits are to be made with the Mortgagee.

     2.4.3. The Mortgagor will pay all taxes and other governmental charges
(including, without limitation, stamp taxes), except income or franchise taxes
or similar taxes based upon or measured by income, assessed by the United States
government or any state or local governmental authority and imposed on the
Mortgagee, its successors by reason of the ownership of this Mortgage or the
Note or the receipt of the interest or other sums payable thereunder or payable
by either the Mortgagor or the Mortgagee upon any increase in the indebtedness
secured hereby, or any modification, amendment, extension or consolidation of
this Mortgage. Without limiting the foregoing and subject to the limitations set
forth above, the Mortgagor will also pay the whole of any tax imposed, directly
or indirectly, on this Mortgage or the Note or the receipt of any portion of the
Indebtedness in lieu of a tax on the Mortgaged Premises or the Improvements and
Building Service Equipment, whether by reason of (a) the passage after the date
of this Mortgage of any law of the State deducting from the value of real
property for the purposes of taxation any lien thereon; (b) any change in the
laws for the taxation of Mortgages or debts secured by Mortgages for state or
local purposes; (c) a change in the means of collection of any such tax or
otherwise; or (d) any tax, whether or not now existing, assessed against, or
withheld from, interest or other payments made by the Mortgagor or assessed
against this Mortgage and which are assessed or levied by the government of any
foreign nation or political subdivision thereof, provided such tax liability
shall not result from the ownership of this Mortgage by a Person not a citizen
of, or an entity not formed under the laws of, the United States or any state.
Within a reasonable time after payment of any such tax or governmental charge,
the Mortgagor will deliver to the Mortgagee satisfactory proof of payment
thereof, subject, however, to the right of the Mortgagor to contest Impositions
as hereinafter set forth. If the Mortgagor shall fail to pay such tax or charge
within fifteen (15) days after written notice, or if under applicable law the
Mortgagor's payment or agreement to pay the same shall be unenforceable, the
Mortgagee shall have the right to declare the entire unpaid indebtedness and all

                                     - 11 -

accrued and unpaid interest thereon due and payable on a date specified by the
Mortgagee, but, in any event, not less than thirty (30) days after written
notice to the Mortgagor.

     2.4.4. The Mortgagor shall have the right to contest the amount or
validity, in whole or in part, of any Imposition, or to seek a reduction in the
valuation of the Mortgaged Premises, or any part thereof, as assessed for real
estate or personal property tax purposes by appropriate proceedings diligently
conducted in good faith, but only after payment of such Imposition, unless such
payment would operate as a bar to such contest or materially adversely interfere
with the prosecution thereof, in which event the Mortgagor may postpone or defer
payment of such Imposition (but not the payment of any monthly deposits pursuant
to SECTION 2.4.2 hereof); and upon request by the Mortgagor, the Mortgagee shall
postpone or defer payment of such Imposition; provided, however, that if at any
time the Mortgaged Premises, the Building Service Equipment, the Furnishings, or
any part thereof would, in the Mortgagee's reasonable judgment, by reason of
such postponement or deferment be in imminent danger of being forfeited or lost,
or if the Mortgagee might be subjected to any civil or criminal liability or
other sanction, then the Mortgagor, on demand, shall immediately pay or cause to
be paid the amount so contested and unpaid, together with all interest and
penalties in connection therewith.

     2.4.5. The certificate, advice or bill of the appropriate official
designated by law to make or issue the same or to receive payment of any
Imposition indicating the nonpayment of such Imposition shall be prima facie
evidence that such Imposition is due and payable but unpaid at the time of the
making or issuance thereof.

     2.5. Insurance; Restoration Following Casualty.

     2.5.1. Until the indebtedness secured hereby is paid in full, the Mortgagor
shall at its own expense at all times maintain or cause to be maintained on all
of the Mortgaged Premises (a) comprehensive general liability insurance,
including umbrella liability insurance, covering all claims for bodily injury,
including death, and property damage occurring on, in or about the Mortgaged
Premises in an aggregate amount of not less than Five Million Dollars
($5,000,000) per occurrence, and a single limit of not less than Two Million
Dollars ($2,000,000) per person and per occurrence for personal injury, bodily
injury and property damage; the policy shall have no deductible or self insured
retention requirements; the policy limits of

                                     - 12 -

FRK11624.A05 
285741572 
01/09/97 KDF:

<PAGE>



such insurance, if requested by the Mortgagee, shall be increased from time to
time to reflect what a reasonably prudent owner or lessee of buildings or
improvements similar in type and locality to the Mortgaged Premises would carry;
during any period of substantial alterations or improvements in, on or to the
Mortgaged Premises, the Mortgagor will cause the comprehensive general liability
insurance, including umbrella liability insurance, endorsed to provide owners'
and contractors' protective liability coverage, including completed operations
liability coverage; (b) physical damage insurance (all risk non-reporting
property insurance, including earthquake insurance, with the Mortgagee named as
loss payee), covering the Mortgaged Premises for loss or damages resulting from
the perils of fire, lightning, earthquake, and such other risks and hazards as
are provided under the current standard "Extended Coverage Endorsement" and
vandalism and malicious mischief coverage, for the full replacement value of the
Mortgaged Premises on a stipulated and agreed-amount basis; (c) if the Mortgaged
Premises is in an area identified as a flood hazard area by the Secretary of
Housing and Urban Development, flood insurance, to the extent obtainable, in an
amount equal to the lesser of the full replacement value of the Mortgaged
Premises or the maximum amount available under the Federal flood insurance
program; (d) boiler and machinery insurance covering all boilers, machinery, air
conditioning, pressure vessels, and similar type equipment commonly covered
under a broad-form boiler and machinery policy, in an amount satisfactory to the
Mortgagee; (e) insurance against such other risks of damage, hazards, casualties
and contingencies in such amounts as the Mortgagee shall from time to time
reasonably require, provided that insurance against such other risks, hazards,
casualties or contingencies shall then be commonly carried by prudent owners or
lessees of building or improvements in the locality similar in character,
construction, use and occupancy to the Improvements, Building Service Equipment
and Furnishings on, or constituting a part of, the Mortgaged Premises; and (f)
loss of rents/business interruption coverage in an amount sufficient to pay all
Impositions, insurance premiums, interest and principal installments and all
other amounts due under the Note and the Loan Agreement and the normal operating
expenses of the Mortgaged Premises, all for a period of one (1) year.
Furthermore, the Mortgagee reserves the right to require additional insurance
and/or higher policy limits than heretofore specified if such additional
insurance and/or higher policy limits are commercially reasonable for similar
properties, which right may be exercised by written notice to the Mortgagor,
and, as soon thereafter as practicable, but in any event within

                                     - 13 -

thirty (30) days of the receipt thereof, the Mortgagor agrees to obtain
insurance coverage complying with such notice. The proceeds of all such
insurance (except the insurance specified in SECTION 2.5.1(a)) shall be paid
solely to the Mortgagee and be held, applied or disbursed by the Mortgagee as
provided in SECTIONS 2.5.7 and 2.5.8.

     2.5.2. All insurance required in SECTION 2.5.1 shall be evidenced by valid
and enforceable policies, in form and substance as shall be required by the
Mortgagee from time to time, and issued by and distributed among insurers of
recognized responsibility having an A.M. Best's Guide of A:XII or better, a
financial size category of Class XI or above, and the total limit of liability
shall not exceed ten percent (10%) of the total policyholders' surplus. Such
insurers shall be authorized to do business in the State and in all other
respects shall be reasonably satisfactory to the Mortgagee. The originals of all
such policies, or duplicate copies or certificates thereof, shall be delivered
to the Mortgagee concurrently with the execution and delivery of this Mortgage.
Thereafter, all renewal or replacement policies, or duplicate copies or
certificates thereof, shall be delivered to the Mortgagee not less than thirty
(30) days prior to the expiration date of the policy or policies to be renewed
or replaced, in each case accompanied by evidence reasonably satisfactory to the
Mortgagee that all premiums currently payable with respect to such policies have
been paid in full by or at the direction of the Mortgagor.

     2.5.3. All such insurance policies shall (a) except for any liability
policy required hereunder, contain a standard noncontributory form of mortgagee
clause (in favor of and entitling the Mortgagee to collect any and all proceeds
payable under such insurance), as well as a standard waiver of subrogation
endorsement, all to be in form and substance reasonably satisfactory to the
Mortgagee; (b) provide that such policies may not be cancelled or amended
without at least thirty (30) days prior written notice to the Mortgagee; and (c)
provide that no act, omission or negligence of the Mortgagor, or its agents,
servants or employees, or of any Space Tenant under any Space Lease, which might
otherwise result in a forfeiture of such insurance or any part thereof, shall in
any way affect the validity or enforceability of such insurance insofar as the
Mortgagee is concerned. The Mortgagor shall not carry separate insurance,
concurrent in kind or form or contributing in the event of loss with any
insurance required under this SECTION 2.5. All losses under such insurance
policies shall be adjusted by the Mortgagor in the

                                     - 14 -

case of any single instance of such damage or destruction not exceeding
$200,000, by the Mortgagor and the Mortgagee in the case of any such single
instance of damage or destruction exceeding such amount, provided that in no
event shall the Mortgagor approve or consent to any final adjustment in any
amount exceeding the amount specified above in this sentence without obtaining
the Mortgagee's prior approval (which approval shall not be unreasonably
withheld) of the amount of such adjustment, and solely by the Mortgagee in the
case when an Event of Default exists and is continuing.

     2.5.4. The Mortgagor, at its expense, will furnish to the Mortgagee, within
ninety (90) days after written demand, but in no event, except for reasonable
cause, more frequently than annually, proof of the then full replacement value
of each of the Improvements and the Building Service Equipment and Furnishings
therein, such proof to be by appraisals reasonably satisfactory in form and
substance to the Mortgagee and prepared by an appraiser (who may be an appraiser
for the insurance company insuring such property) designated and paid for by the
Mortgagor and approved by the Mortgagee, which approval shall not be
unreasonably withheld or delayed.

     2.5.5. If the Mortgagee shall, by any means, acquire the title or estate of
the Mortgagor in or to any portion of the Mortgaged Premises, it shall thereupon
become the sole and absolute owner of all insurance policies affecting such
portion of the Mortgaged Premises held by, or required hereunder to be delivered
to, the Mortgagee, with the sole right to collect and retain all unearned
premiums thereon; and the Mortgagor shall be entitled only to a credit in
reduction of the then outstanding indebtedness secured hereby in the amount of
the short rate cancellation refund, when and if received by Mortgagee. The
Mortgagor agrees, immediately upon demand, to execute and deliver such
assignments or other authorizations or instruments as may, in the reasonable
opinion of the Mortgagee, be reasonably necessary or desirable to effectuate any
of the provisions of this SECTION 2.5.5.

     2.5.6. If any of the Improvements, Building Service Equipment or
Furnishings shall be damaged or destroyed, in whole or in part, by fire or other
casualty, the Mortgagor shall give prompt notice thereof to the Mortgagee, and,
without regard to the availability or adequacy of insurance proceeds, shall
promptly following receipt of any insurance proceeds or the date when any such
proceeds are made available to the Mortgagor in accordance

with the terms hereof, commence to restore, replace, rebuild or alter the same
as nearly as possible to the condition, character and value thereof existing
immediately prior to such damage or destruction. Any insurance proceeds in
respect of such damage or destruction, or any Award (as defined in SECTION 3.2)
for a partial taking which is not a substantial or total taking, as such terms
are referred to in ARTICLE III hereof, at the option of the Mortgagee, may
either (i) be applied as a prepayment of the unpaid balance of the principal of
the Note and of accrued and unpaid interest thereon and as a payment of any
other sums due and owing under the Note, the Loan Agreement and the Security
Documents, or (ii) be made available to pay or reimburse costs incurred for
restoration, replacement or rebuilding necessitated as a result of such damage
or destruction, or as a result of such taking, as the case may be, or (iii) be
used for any other purpose or object deemed appropriate by the Mortgagee in
connection with the Mortgaged Premises, provided, however, that the Mortgagee
may not elect either option (i) or (iii) above if, and for so long as all of the
following conditions (collectively, the "Insurance or Award Conditions" have
been and remain satisfied: (a) no Event of Default has occurred and is
continuing or would occur as a result of such casualty or taking and no event
has occurred that with the passage of time or the giving of notice, or both,
would constitute an Event of Default; (b) the balance of the insurance proceeds
or such Award either initially paid to the Mortgagee or deposited with the
Depository (as hereinafter defined) or remaining from time to time, shall be
sufficient, in the Mortgagee's reasonable judgment, to complete the restoration,
replacement or rebuilding, or the Mortgagor shall have deposited such sufficient
funds with the Mortgagee or the Depository; and (c) the Mortgagee determines, in
its reasonable discretion, that (i) the Loan to Value Ratio (as defined in the
Loan Agreement, and taking into consideration the value of all of the Projects,
as defined in the Loan Agreement) is not greater than 55%, and (ii) the Debt
Service Coverage Ratio (as defined in the Loan Agreement, and taking into
consideration the loss of income resulting from such damage or destruction as
projected by the Mortgagee in its reasonable discretion) is not less than
1.40:1.0. Notwithstanding the foregoing, if an event has occurred and is
continuing that with the passage of time or the giving of notice, or both, would
constitute an Event of Default but the same has not yet matured into an Event of
Default, then, if the conditions set forth in the foregoing clauses (b) and (c)
have been or will be, in the Mortgagee's reasonable judgment, satisfied, the
Mortgagee shall not elect either option (i) or (iii) unless such event shall
have matured into an Event of Default and, unless and until

                                     - 16 -

such event shall have so matured into an Event of Default or such event has been
cured or shall otherwise cease to exist, the Mortgagee (or the Depository) shall
not release any such insurance proceeds or Award and the same shall be held
until an Event of Default occurs or the Default has been cured or shall
otherwise cease to exist.

     2.5.7. Any such insurance proceeds (other than the proceeds of the rent
insurance policy, which shall be paid as provided in SECTION 2.5.8 below) or
Award which are to be applied to restoration, replacement or rebuilding of the
Mortgaged Premises shall, after payment or reimbursement to the Mortgagee of all
reasonable costs and expenses of the Mortgagee in collecting such proceeds or
Award, be applied upon satisfaction of the following provisions and conditions:

          (a) If the damage be of such nature as to require the Mortgagor to
     construct a replacement for, or to alter in any material or substantial
     way, the damaged or destroyed items, the Mortgagor shall, before commencing
     any such work, submit copies of the plans and specifications therefor to
     the Mortgagee for the Mortgagee's approval, such approval to not be
     unreasonably withheld or delayed.

          (b) If after payment or reimbursement to the Mortgagee of all costs
     and expenses of the Mortgagee in collecting such insurance proceeds or
     Award, the aggregate insurance proceeds or Award received by reason of any
     single instance of such damage or destruction or condemnation, as the case
     may be, shall be $200,000 or less such insurance proceeds or Award shall be
     paid to the Mortgagor, which shall hold all amounts so received in trust
     for application first to pay the entire cost of restoring, repairing,
     rebuilding or replacing the damaged or destroyed items, before any portion
     of such proceeds may be used or applied for any other purpose. If the
     aggregate net insurance proceeds or Award by reason of any single instance
     of such damage or destruction or condemnation, as the case may be, shall be
     more than $200,000 such sums shall be held and disbursed by Fleet Bank,
     National Association or, if this Mortgage is held by another financial
     institution, by such financial institution or, if this Mortgage is not held
     by a financial institution, by a financial institution selected by the then
     Mortgagee (the holder of such monies, the "Depository") in accordance with
     the following provisions of this SECTION 2.5.7.

          (c) The Mortgagee shall have received as to each such disbursement a
     certificate of the Mortgagor (i) requesting the payment of a specified
     amount of such insurance or condemnation proceeds; (ii) describing in
     reasonable detail the work and materials applied to the restoration,
     replacement or rebuilding of the damaged, destroyed or taken Improvement,
     or Building Service Equipment and/or Furnishings located therein, since the
     date of the last such certificate; (iii) stating that the requested amount
     does not exceed the cost of such work and materials; and (iv) stating that
     a request for payment for such work and materials has not previously been
     made, accompanied by:

               1. a certificate of an independent engineer or architect
          designated by the Mortgagor, who shall have been approved in writing
          by the Mortgagee (such approval not to be unreasonably withheld),
          stating (i) that the work and materials described in the accompanying
          certificate of the Mortgagor were satisfactorily performed and
          furnished and were necessary, appropriate or desirable to the
          restoration, replacement or rebuilding of the damaged, destroyed or
          taken Improvement, or Building Service Equipment and/or Furnishings;
          (ii) that the amount specified in such certificate of the Mortgagor
          does not exceed the reasonable cost of such work and materials; and
          (iii) the additional amount, if any, required to complete the
          restoration, replacement or rebuilding of the damaged, destroyed or
          taken Improvement, Building Service Equipment and/or Furnishings; and

               2. evidence reasonably satisfactory to the Mortgagee (i) that
          there exists no filed or recorded lien, or lien notice, or encumbrance
          or charge in respect of all or any part of the Mortgaged Premises that
          is prior to or on a parity with the lien of this Mortgage, except as
          may be permitted in the Permitted Encumbrances; (ii) that neither the
          Mortgaged Premises nor any part thereof is subject to any recorded or
          filed mechanic's, laborer's, materialman's or any similar lien,
          encumbrance or charge; and

          (iii) that none of the Building Service Equipment and Furnishings
          provided in connection with such restoration, replacement or
          rebuilding is subject to any security interest other than in favor of
          the Mortgagee;

     Upon satisfaction of the conditions set forth herein, the Mortgagee shall
pay to the Mortgagor the amount of such insurance or condemnation proceeds
requested in such certificate of the Mortgagor or consent to the Depository's
payment thereof, as the case may be; provided, however, that in no event shall
the balance of insurance or condemnation proceeds held by the Mortgagee and the
Depository be reduced below the amount specified in such certificate of the
independent engineer or architect as the amount required to complete the
restoration, replacement or rebuilding of the damaged, destroyed or taken
Improvement, Building Service Equipment and/or Furnishings. Each such payment,
whether made by the Mortgagee or the Depository, shall be held by the Mortgagor
in trust and shall be used solely for the payment of the cost of the work and
materials described in the certificate of the Mortgagor, or if such cost or any
part thereof has theretofore been paid by the Mortgagor out of its own funds,
then for the reimbursement to the Mortgagor of any such cost or part thereof
paid by it. Any balance of insurance or condemnation proceeds held by the
Mortgagee after the completion of the restoration, replacement or rebuilding and
payment of all costs incurred in connection therewith, to be evidenced by a
certificate to such effect of such independent engineer or architect delivered
to the Mortgagee, shall, if no Event of Default shall have occurred and be
continuing, be released to the Person lawfully entitled thereto. Notwithstanding
the foregoing, if the Mortgagor needs to make deposits with or payments to
contractors prior to the work being performed, if the Mortgagee is otherwise
obligated to allow funds to be used to rebuild or restore, the Mortgagee agrees
that it will not unreasonably withhold or delay its consent to the Mortgagor's
request that such deposits or advances payments be allowed.

     2.5.8. All proceeds of rent insurance payable as a result of the occurrence
of any fire or other casualty which affects the Mortgaged Premises, or any part
thereof, shall be paid to the Mortgagee or, if the Mortgagee is not a financial
institution, the Depository. The Mortgagee or the Depository, as the case may
be, if it shall receive such proceeds, shall hold such proceeds in trust if
permitted under law, and in an account bearing interest

(payable to or for account of the Mortgagor), and shall apply or cause such
proceeds (including any net interest thereon) to be applied to the payment of
those items referred to in SECTION 2.5.1(f) which become, and as they become,
due and payable from and after the date of the occurrence of such damage or
loss, until the completion of the necessary restoration or replacement by the
Mortgagor or until the exhaustion of such proceeds (including any interest
thereon), whichever first occurs. Upon completion of such restoration or
replacement, any balance of such rent insurance proceeds, together with the
interest thereon, if any, not theretofore applied as provided herein, in the
hands of the Mortgagee or the Depository, as the case may be, shall, provided
that no Event of Default shall have occurred and be continuing, be paid to the
Person lawfully entitled thereto.

     2.5.9. Nothing in this SECTION 2.5 contained shall (i) relieve the
Mortgagor of its duty to repair, restore, rebuild or replace the Improvements,
Building Service Equipment and/or Furnishings following damage or destruction by
fire or other casualty or taking in the event that no Award or an inadequate
Award or that no or inadequate proceeds of insurance are available to defray the
cost of such repairing, restoring, rebuilding or replacement (provided, however,
the Mortgagor shall be permitted to receive the insurance proceeds upon
satisfaction of the conditions set forth herein provided, in addition, that all
of the Insurance or Award Conditions have been and remain satisfied), or (ii)
relieve the Mortgagor of its obligation to pay principal and interest and to
make all other payments required by the Note, the Loan Agreement and this
Mortgage subsequent to the occurrence of any fire or other casualty, or taking,
except if, and to the extent that, any proceeds of rent insurance are applied by
the Mortgagee in accordance with SECTION 2.5.8 to such required payments.

     2.5.10. If, while any insurance proceeds or Award is being held by the
Mortgagee or the Depository, an Event of Default shall occur and be continuing,
the Mortgagee shall be entitled to receive and apply all such insurance proceeds
or Award in reduction of the indebtedness and other obligations secured by this
Mortgage, in such order and respective amounts, as the Mortgagee in its
discretion shall determine.

     2.6. To Comply with Laws.

     2.6.1. The Mortgagor, at its own expense, will promptly cure all violations
of law affecting the Mortgaged Premises, or any part thereof, and/or the use and
operation thereof and will promptly comply, or cause to be complied with, all
present and future Legal Requirements. However, the Mortgagor shall have the
right, after prior notice to the Mortgagee, to contest by appropriate legal
proceedings, diligently conducted in good faith, the validity or application of
any Legal Requirement if and so long as the Mortgagor shall promptly furnish to
the Mortgagee a certificate to such effect showing the steps taken to comply
with such provisions, provided that:

          (a) if by the terms of any such Legal Requirement, compliance
     therewith pending the prosecution of any such proceeding may be delayed
     legally without incurring any lien, charge or liability of any kind against
     the Mortgaged Premises, or any part thereof, and without subjecting the
     Mortgagor or the Mortgagee to any liability, civil or criminal, for failure
     so to comply therewith, the Mortgagor may delay compliance therewith until
     the final determination of any such proceeding; and

          (b) if any lien, charge or civil liability would be incurred by reason
     of any such delay, the Mortgagor nevertheless, on the prior written consent
     of the Mortgagee, such consent not to be unreasonably withheld, may contest
     and delay compliance with the Legal Requirement, provided that such delay
     would not subject the Mortgagee to criminal liability and the Mortgagor (i)
     furnishes to the Mortgagee security reasonably satisfactory to the
     Mortgagee against loss or injury by reason of such contest or delay and
     (ii) prosecutes the contest with due diligence.

     2.6.2. Notwithstanding the provisions of SECTION 2.6.1, if any delay in
compliance with any Legal Requirement shall, in the reasonable judgment of the
Mortgagee, place all or any part of the Mortgaged Premises in imminent danger of
being forfeited or lost, the Mortgagor shall, upon written notice from the
Mortgagee, immediately comply with such Legal Requirement.

     2.6.3. The Mortgagor will use and permit the use of the Mortgaged Premises
only in accordance with 

                                     - 21 -

the material requirements of any applicable licenses and permits issued by
Governmental Authorities.

     2.6.4. The Mortgagor will procure, pay for and maintain (or cause to be
procured, paid and maintained) all permits, licenses and other authorizations
required to be procured and maintained by the owners and operators of the
Mortgaged Premises for any then use of all or any part of the Mortgaged Premises
then being made and for the lawful and proper operation and maintenance thereof.

     2.7. Limitation on Alterations and Demolition.

     2.7.1. The Mortgagor shall not voluntarily demolish, replace or alter the
Mortgaged Premises, or any part thereof, or voluntarily make any addition
thereto, or voluntarily construct any additional improvements thereon, or suffer
any of the same to occur, whether structural or otherwise (collectively,
"change"), without the prior written consent of the Mortgagee, which consent
shall not be unreasonably withheld or delayed; provided, however, that if no
Event of Default is continuing and such change involves an estimated cost of
less than $100,000 and is non-structural or if no Event of Default is continuing
and such change is non-structural and is being made to prepare space for a Space
Tenant pursuant to a Space Lease entered into in accordance with the Loan
Agreement, then, in either of such events, the Mortgagee's consent shall not be
required; provided, further, however, that if any such change is required by
law, the Mortgagor may make such change with the prior written consent of the
Mortgagee, which consent the Mortgagee will not unreasonably withhold or delay.
As a condition to any consent under this SECTION 2.7.1, the Mortgagee may
require (a) that plans and specifications for the proposed work, prepared by a
reputable architect reasonably satisfactory to the Mortgagee, be submitted to
the Mortgagee for approval, and (b) that the Mortgagor obtain a payment and
performance bond or other security reasonably satisfactory to the Mortgagee in
form and amount reasonably satisfactory to the Mortgagee from the contractor or
subcontractor performing the work unless such work amounts to less than $200,000
in aggregate total cost. All work performed by or on behalf of the Mortgagor
shall be completed with all reasonable diligence and continuity, in a good and
workmanlike manner, and in compliance with all applicable Legal Requirements.
Unless, and to the extent that, the provisions of SECTION 2.7.2 be applicable,
no Building Service Equipment or Furnishings shall be removed from the Mortgaged
Premises during the course of any such work without prior notification to the
Mortgagee and unless 

                                     - 22 -

provision is made for return or replacement on or prior to the completion of the
work. The provisions of this SECTION 2.7.1. shall apply to any change made or
required to be made by the Mortgagor in the course of complying with any other
of the provisions of this Mortgage. A duplicate set of all plans and
specifications required to be filed with any Governmental Authority prior to, or
at any time in connection with, any such alteration, demolition or new
construction shall be furnished to the Mortgagee. The Mortgagor will pay on
demand the reasonable expenses incurred by the Mortgagee in the review of plans
and specifications provided for in this Mortgage.

     2.7.2. The Mortgagor shall have the right, at any time and from time to
time, to remove and dispose of any item of Building Service Equipment or
Furnishings which may have become obsolete or unfit for use or which is no
longer useful in the operation of the Improvements, provided that the Mortgagor
promptly replaces such item with other Building Service Equipment or
Furnishings, free of superior title, liens or claims (other than in favor of the
Mortgagee) unless consent of the Mortgagee is first obtained, not necessarily of
the same character but of at least equal quality, value and usefulness in
connection with the operation and maintenance of the Mortgaged Premises,
provided, further, however, no removal of any item of Building Service Equipment
or Furnishings then having a fair market value of $50,000 or more shall be made
without the prior written consent of the Mortgagee, which consent will not be
unreasonably withheld or delayed. However, if by reason of technological or
other developments in the operation and maintenance of buildings and other
improvements of the general character of the Improvements or a change in the use
of the Mortgaged Premises or any part thereof, no replacement of the Building
Service Equipment or Furnishings so removed would be necessary or desirable for
the proper operation or maintenance of the Improvements, the Mortgagor shall not
be required to replace the item so removed.

     2.8. Limitation on Disposition of the Mortgaged Premises.

     2.8.1. Except as expressly set forth in this Mortgage or the Loan Agreement
(including, without limitation, SECTIONS 5.01 and 6.21 of the Loan Agreement),
the Mortgagor shall not directly or indirectly sell, assign, mortgage, alienate,
pledge or otherwise transfer or further encumber the Mortgaged Premises or any
part thereof or any interest therein or in any of the rents, profits or income

                                     - 23 -

generated thereby, whether voluntarily, involuntarily, by operation of law or
otherwise, or lease all or any portion thereof or an undivided interest therein,
without the prior written consent of the Mortgagee. The foregoing events are
hereinafter referred as a "Transfer". Any transfer without prior written the
consent of the Mortgagee is an Event of Default.

     2.8.2. If there shall be a violation of the terms and provisions of SECTION
2.8.1, whether by the Mortgagor or any other person, in addition to all other
rights and remedies available to the Mortgagee under this Mortgage, the
Mortgagee shall have the option, by the giving of notice to the Mortgagor, of
declaring the entire unpaid principal balance of the Note, together with all
accrued and unpaid interest and all other sums and charges evidenced thereby or
payable pursuant to the Loan Agreement, immediately due and payable.

     2.9. Maintenance of Mortgaged Premises; Covenant Against Waste; Inspection
by the Mortgagee. The Mortgagor will not commit or permit waste on the Mortgaged
Premises and, at its expense, will keep and maintain the Improvements, the
Building Service Equipment and Furnishings in its (or their) present state of
repair and condition, reasonable wear and tear excepted, and, if improved, in
such improved state of repair and condition, reasonable wear and tear excepted;
provided, that this shall not limit the Mortgagor's other obligations hereunder,
such as compliance with laws. The Mortgagor shall do or cause to be done all
maintenance and make or cause to be made all repairs as may be required by the
landlord under any Space Lease. The Mortgagor will neither do nor permit to be
done anything to the Mortgaged Premises that may materially impair the value
thereof or which may violate any covenant, condition or restriction affecting
the Mortgaged Premises, or any part thereof, or which would effect any material
change therein or in the condition thereof that would increase the danger of
fire or other hazard arising out of the operation of the Mortgaged Premises.
Subject to the rights of Space Tenants, the Mortgagee, and its representatives
and agents, may enter and inspect the Mortgaged Premises at any time after
reasonable notice (which may be oral) during usual business hours, and the
Mortgagor shall, within thirty (30) days after demand by the Mortgagee (or
immediately upon demand in case of emergency), make such repairs, replacements,
renewals or additions, or perform such items of maintenance, to the Mortgaged
Premises as the Mortgagee may reasonably require in order to cause the Mortgaged
Premises to comply with the standards established in this SECTION 2.9.

     2.10. To Furnish Certificates; Other Reporting Requirements.

     2.10.1. The Mortgagor will, at its own expense, deliver to the Mortgagee,
within fifteen (15) days after written request, but no more frequently than once
per six (6) month period, a written statement executed by the Mortgagor, in
recordable form, setting forth to the best of the Mortgagor's knowledge, the
amount then unpaid upon the Note and secured by this Mortgage and stating
whether any offsets or defenses exist against the indebtedness secured hereby;
and, if any such offsets or defenses are alleged to exist, then the factual
basis and amount of such claimed offsets or defenses.

     2.10.2. The Mortgagor will, if requested by the Mortgagee, deliver to the
Mortgagee a certificate of an officer of the general partner of the Mortgagor or
of such general partner's general partner, to the effect that he is familiar
with this Mortgage and the other Security Documents, has reviewed the affairs of
the Mortgagor, and to the best of his knowledge and belief there exists no Event
of Default and no act or event has occurred or exists which with notice or lapse
of time or both could become such an Event of Default, or if any such event or
Event of Default exists, specifying it and what action the Mortgagor is taking
to cause it to be remedied.

     2.11. After-Acquired Property. All right, title and interest of the
Mortgagor in and to all improvements, betterments, renewals, substitutes and
replacements of, and all additions and appurtenances to, the Mortgaged Premises
hereafter acquired, constructed, assembled or placed on the Mortgaged Premises,
immediately upon such acquisition, construction, assembly or placement, as the
case may be, and in each such case without any further mortgage, conveyance or
assignment or other act of the Mortgagor, shall become subject to the lien of
this Mortgage as fully and completely, and with the same effect, as though now
owned by the Mortgagor and specifically described in the granting clauses
hereof; and at any time and from time to time the Mortgagor, on demand, will
execute, acknowledge and deliver to the Mortgagee any and all such further
assurances, mortgages, conveyances or assignments as the Mortgagee may
reasonably require to further evidence, confirm and perfect the provisions of
this SECTION 2.11.

     2.12. Further Assurances. The Mortgagor shall, at its sole cost and without
expense to the Mortgagee, on demand, do, execute, acknowledge and deliver all
and every

such further acts, deeds, conveyances, mortgages, assignments, notices of
assignment, transfers and assurances as the Mortgagee shall from time to time
reasonably require for better assuring, conveying, assigning, transferring and
confirming unto the Mortgagee the property and rights hereby mortgaged or
assigned or intended now or hereafter so to be, or which the Mortgagor may be or
may hereafter become bound to convey, mortgage or assign to the Mortgagee, or
for carrying out the intention or facilitating the performance of the terms of
this Mortgage, or for filing, registering or recording this Mortgage.

     2.13. Recorded Instruments. The Mortgagor will promptly perform and
observe, or cause to be performed and observed, all of the terms, covenants and
conditions of all instruments of record affecting the Mortgaged Premises (other
than non-consensual encumbrances hereafter affecting the Mortgaged Premises, the
validity or enforceability of which the Mortgagor is contesting in accordance
with this Mortgage) where non-compliance therewith affects the security of this
Mortgage or imposes any duty or obligation upon the Mortgagor or any Space
Tenant. The Mortgagor shall do or cause to be done all things reasonably
required to preserve intact and unimpaired and to renew any and all
rights-of-way, easements, grants, appurtenances, privileges, licenses,
franchises and other interests and rights in favor of or constituting any
portion of the Mortgaged Premises. The Mortgagor will not, without the prior
written consent of the Mortgagee, which consent shall not be unreasonably
withheld or delayed, initiate, join in or consent to any private restrictive
covenant or other public or private restriction as to the use of all or any
portion of the Mortgaged Premises. The Mortgagor will, however, comply with all
lawful restrictive covenants and zoning ordinances and other public or private
restrictions affecting all or any portion of the Mortgaged Premises.

                                  Condemnation


     3.1. Notice of Taking. The Mortgagor shall promptly notify the Mortgagee if
the Mortgagor receives notice of the institution of any proceeding or
negotiations for the taking of the Mortgaged Premises, or any part thereof,
whether for permanent or temporary use and occupancy in condemnation or by the
exercise of the power of eminent domain or by agreement of interested parties in
lieu

of such condemnation (all the foregoing called a "taking"); shall keep the
Mortgagee currently advised, in detail, as to the status of such proceedings or
negotiations and will promptly give to the Mortgagee copies of all notices,
pleadings, judgments, determinations and other papers received or delivered by
the Mortgagor in connection with any such proceedings. The Mortgagee shall have
the right to appear and participate in such proceedings and may be represented
by counsel. The Mortgagor will not, without the Mortgagee's prior written
consent, which consent shall not be unreasonably withheld or delayed, enter into
any agreement for the taking of the Mortgaged Premises, or any part thereof,
with anyone authorized to acquire the Mortgaged Premises by eminent domain or in
condemnation.

     3.2. Condemnation Award. If the Mortgaged Premises shall be the subject of
a taking the Mortgagee shall be entitled to and shall receive the total of such
portion of all awards made that shall be allowed to the Mortgagor with respect
to all the right, title and interest of the Mortgagor in and to the Mortgaged
Premises (the award made in any total, partial or temporary taking is herein
called the "Award"), provided that the obligations of the Mortgagor to perform
the terms, covenants and conditions of this Mortgage, if any, affected by such
taking shall continue unimpaired until the actual vesting of title in such
proceeding and the actual receipt by the Mortgagee of the Mortgagor's share of
the entire Award resulting from such taking.

     3.3. Application of Award. The Mortgagee shall have the option of treating
a total taking or a substantial taking (as hereinafter defined) as an Event of
Default and of accelerating the entire indebtedness secured hereby, in which
event it shall apply the Mortgagor's entire Award in reduction of such
indebtedness (including principal, interest and other sums secured hereby, in
such order as the Mortgagee may determine) and shall turn over any balance
remaining, if any, to the Person lawfully entitled thereto; or if the Mortgagee
shall not so elect to accelerate the indebtedness and apply the Award thereto,
then the total Award shall, regardless of amount, be deposited with the
Mortgagee or with the Depository, the Mortgagor hereby agreeing to elect that
such proceeds be held and disbursed by the Depository in accordance with
SECTIONS 2.5.6, 2.5.7, 2.5.8, 2.5.9 and 2.5.10 hereof for restoration required
to be made by the Mortgagor. If there be a partial taking, the net proceeds of
the Award shall be deposited with the Mortgagee and applied by the Mortgagee in
accordance with the provisions of SECTIONS 2.5.6, 2.5.7, 2.5.9 and 2.5.10.

<PAGE>



Any Award remaining after the completion of such restoration, replacement or
rebuilding shall be applied in reduction of the indebtedness (including
principal, interest and other sums secured hereby) in such order as the
Mortgagee shall determine. A partial taking is substantial only if it materially
decreases the fair market value of the Mortgaged Premises and the remainder of
the Mortgaged Premises cannot be restored to an economically viable whole.

     3.4. Temporary Taking. If any Award payable to the Mortgagor on account of
a taking for temporary use or occupancy is made in a lump sum or is payable
other than in equal monthly installments, the Mortgagor shall pay over such
Award to the Depository and such Award shall be applied to installments of
Impositions and of principal and interest and all other charges secured by this
Mortgage or due under the Note, the Loan Agreement, or the other Security
Documents as and when the same become due and payable. Any unapplied portion of
such Award held by the Depository when such taking ceases or expires (if no
Event of Default has then occurred and is continuing), or after the indebtedness
secured by this Mortgage or due under the Loan and Security Documents shall have
been paid in full, shall be paid to the Person lawfully entitled thereto.

     3.5. The Mortgagor's Obligation to Restore. If all available proceeds of
the Award are made available to the Mortgagor for restoration, replacement or
rebuilding pursuant hereto, the Mortgagor shall be obligated promptly to
restore, replace, rebuild or alter any Improvements or Building Service
Equipment affected by a taking so as to restore the Mortgaged Premises to an
economically viable whole, all without regard to the adequacy of the proceeds of
an Award, if any, made available to the Mortgagor.

                   Assignment of Space Leases, Rents, Profits
                   and Other Income as Further Security, Etc.


     4.1. Assignment of Space Leases, Rents, Issues and Profits. Subject to the
Mortgagor's rights herein, including those set forth in SECTION 4.3.2 below, the
Mortgagor hereby absolutely, presently and irrevocably transfers, assigns and
sets over unto the Mortgagee all right, title and interest of the Mortgagor in
and to all Space Leases, if any, now or hereafter entered into with

respect to all or any part of the Mortgaged Premises, and all renewals,
extensions, subleases or assignments thereof, and all other occupancy agreements
(written or oral), by concession, license or otherwise, together with all of the
rents, income, receipts, revenues, issues and profits arising therefrom (the
"Collateral").

     4.2. The Mortgagor's Covenants Regarding Space Leases.

     4.2.1. Without the prior consent and approval of the Mortgagee in each
instance, the Mortgagor will not (a) assign, pledge, hypothecate or otherwise
encumber any of the Space Leases or the rents, income, issue and profits of the
Mortgaged Premises; or (b) enter into any Space Leases affecting the Mortgaged
Premises or any part thereof, unless such Space Lease is expressly subordinate
to the lien of this Mortgage and to any consolidation, extension, renewal,
recasting or refinancing hereof and the Space Lease provides, in substance, that
in the event of enforcement by the Mortgagee of the remedies provided for by law
or by this Mortgage, each Space Tenant shall, at the option of the Mortgagee,
enter into a agreement with the Mortgagee which shall provide, among other
things, that (i) such Space Tenant shall attorn to any person succeeding to the
interest of the Mortgagor as a result of such enforcement and shall recognize
such successor in interest as landlord under such Space Lease without change in
the terms or other provisions thereof, (ii) such successor shall not be bound by
any payment of rent or additional rent for more than one (1) month in advance or
any amendment or modification of any such Space Lease made without the
Mortgagee's written consent, and (iii) such successor shall not disturb the
possession of the Space Tenant provided certain conditions (as determined by the
Mortgagee) have been satisfied, including, without limitation, that the Space
Tenant shall not be in default under the terms of the Space Lease; or (c) enter
into any Space Leases without the prior written consent of the Mortgagee unless
permitted in SECTION 6.21 of the Loan Agreement.

     4.2.2. The Mortgagor further represents, warrants, covenants and agrees
that:

          (a) To the best of its knowledge, each Space Lease is (or, when
     executed, will be) a valid and legally enforceable obligation of the
     parties thereto, in full force and effect.

<PAGE>


          (b) With respect to each Space Lease and the Space Tenant security
     deposits thereunder, any and/or all of such security deposits shall be held
     as required by the Space Lease but in no event in a manner other than that
     required by law.

          (c) The Mortgagor shall, at its sole cost and expense, keep, observe,
     perform and discharge, duly and punctually, all and singular the material
     obligations, terms, covenants, conditions, representations and warranties
     of each Space Lease on the part of the Mortgagor to be kept, observed,
     performed and discharged.

          (d) (i) Except as herein in this clause (i) expressly provided, the
     Mortgagor shall, at its sole cost and expense, maintain the Space Leases in
     full force and effect; the Mortgagor will not waive its rights under or
     materially modify, change, supplement, alter or amend ("Change"), nor shall
     the Mortgagor surrender (whether partial or total), terminate, cancel or
     subordinate, any of the Space Leases or enter into any Backlease (whether
     through an Affiliate or otherwise), and any such attempted Change,
     surrender, termination, cancellation or subordination or Backlease shall be
     void, unless, in each case, the prior written consent thereto of the
     Mortgagee shall have been obtained. Notwithstanding the foregoing, the
     Mortgagor may (x) terminate any Space Lease under 10,000 rentable square
     feet as a result of a default by the tenant under such Space Lease and (y)
     consent to any sublease or assignment of any Space Lease under 10,000
     rentable square feet provided (aa) such termination is being effected in
     the ordinary course of the Mortgagor's business, (bb) no Event of Default
     then exists and no event has occurred that with the passage of time or the
     giving of notice or both would constitute an Event of Default, and (cc) the
     Mortgagee determines, in its reasonable discretion, that upon the
     effectiveness of such termination, assignment or sublease (i) the Loan to
     Value Ratio (as defined in the Loan Agreement, and taking into
     consideration the value of all of the Projects, as defined in the Loan
     Agreement) is not greater than 55%, and (ii) the Debt Service Coverage
     Ratio (as defined in the Loan Agreement, and taking into consideration the
     loss of income resulting from such termination, assignment or sublease, as
     projected by the Mortgagee in its reasonable discretion) is not less than
     1.40:1.0. A material Change shall include but not be limited to any
     material Change in the amount

     or time of payment of the rent or additional rent, the length of term or
     square footage of the premises under any Space Lease or any other Change
     which would materially adversely affect the Mortgagor's rights under the
     Space Lease, or would affect the Mortgagee's rights under the Space Lease
     or the value of the Space Lease as collateral security for the
     indebtedness.

               (ii) The Mortgagor shall, at its sole cost and expense, enforce
          the Space Leases in accordance with their terms; and shall appear in
          and defend any action or proceeding arising to which it is a party
          under or in any manner connected with any of the Space Leases.

          (e) The Mortgagor shall deliver to the Mortgagee a copy of each notice
     of default sent or received by it relating in any way to any Space Lease
     promptly upon, but in any event within five (5) business days after, its
     sending or receipt thereof.

     4.3. The Mortgagor's Rights and Powers.

     4.3.1. The Mortgagor hereby irrevocably, in the name of the Mortgagor or
otherwise, authorizes and empowers the Mortgagee, and assigns and transfers unto
the Mortgagee, and constitutes and appoints the Mortgagee its true and lawful
attorney-in-fact, coupled with an interest and as its agent, irrevocably, with
full power or substitution for it and in its name, but solely for the following
purposes: (i) to exercise and enforce every right, power, remedy, authority,
option and privilege of the Mortgagor under the Space Leases, and as such
attorney-in-fact, the Mortgagee may subordinate, terminate, cancel or modify the
Space Leases, accept the surrender of the Space Leases, give any notice, take
any action resulting in such subordination, termination, cancellation,
modification or surrender, give any authorization, furnish any information, make
any demands, execute any instruments and take any and all other action on behalf
of and in the name of the Mortgagor which in the opinion of the Mortgagee may be
necessary or appropriate to be given, furnished, made, exercised or taken by the
Mortgagor under the Space Leases in order to comply therewith, to perform the
conditions thereof or to prevent or remedy any default by the Mortgagor
thereunder or to enforce any of the Mortgagor's rights and remedies there-under,

releases, receipts, discharges and acquittances thereof; to endorse any checks
or other instruments or orders in connection therewith and to file any claims or
take any action or institute any proceedings which the Mortgagee may deem to be
necessary or advisable; provided, however, that the power provided for in this
sentence may not be exercised by the Mortgagee unless an Event of Default shall
have occurred and be continuing. "Income" shall mean all deposits, rents,
issues, profits, revenues, royalties, and other revenue producing arrangements,
whether written or oral, and all monetary benefits of, and/or derived from,
and/or sums payable under and by virtue of the Space Leases and/or the Premises.

     4.3.2. So long as there shall not have occurred and then be continuing any
Event of Default and until such right of the Mortgagor is terminated by the
Mortgagee as provided in SECTION 4.3.3, the Mortgagee will not exercise its
rights pursuant to SECTION 4.3.1, and, notwithstanding anything in SECTION 4.3.1
to the contrary, the Mortgagor shall have the right (but limited as hereinafter
provided) to exercise all of its rights under the Space Leases, including,
without limitation, to collect and receive all rents, income, receipts,
revenues, issues and profits arising therefrom, provided that the Mortgagor
shall at all times comply with, observe and perform, in the exercise of such
right, all of the provisions of this Mortgage and the other Security Documents
applicable to the Space Leases; provided, further, that no action shall be taken
or failed to be taken by the Mortgagor which would impair the Collateral or any
other collateral security for the Obligations provided for in the Security
Documents.

     4.3.3. The Mortgagee, upon the occurrence and during the continuance of an
Event of Default, at its option and upon written notice to the Mortgagor, shall
have the right to terminate the right of the Mortgagor to exercise its rights
under the Space Leases, and, thereupon, in addition, the Mortgagee, at any time
thereafter, at its option, shall have the complete right, power and authority
hereunder to exercise and enforce all rights, powers, remedies, authority,
options and privileges of the Mortgagor under the Space Leases in the name of
the Mortgagor or the Mortgagee, to enforce all obligations of the other parties
to the Space Leases and to exercise and enforce all of its rights and remedies
hereunder and under law not exercisable prior to an Event of Default.

     4.3.4. The Mortgagor does hereby direct each and all of the Space Tenants
under the Space Leases and

all contractual obligors of the Mortgagor to pay any Income to the Mortgagee
upon written demand for payment thereof by the Mortgagee without further
inquiry. It is understood and agreed, however, that no such demand shall be made
unless an Event of Default shall have occurred and be continuing. No such Space
Tenant or obligor shall be obliged to account to the Mortgagor for any amounts
paid to the Mortgagee by reason of any payment made to the Mortgagee pursuant to
such demand and, upon any such payment to the Mortgagee, shall be pro tanto
released from their obligations to the Mortgagor with respect to such payment.
Each Space Tenant shall be permitted to rely on any communication from the
Mortgagee pursuant hereto, and under no circumstances shall such Space Tenant be
obligated to the Mortgagor for any payments made to the Mortgagee hereunder.
Until such demand is made, the Mortgagor is authorized to collect or enforce or
continue collecting or enforcing such Income in accordance with the provisions
of this Mortgage.

     4.3.5. The Mortgagee shall not have any duty as to the collection or
protection of the Collateral or any income thereon or payments with respect
thereto, or as to the preservation of any rights pertaining thereto beyond the
safe custody of any thereof actually in its possession. In no instance shall the
Mortgagee be responsible to lessees for payment of interest upon, or return of,
any lease security deposits, except as provided by law or as provided in the
leases and then only if and to the extent that such deposits are received by the
Mortgagee. The Mortgagor hereby waives notice of acceptance hereof, and except
as otherwise specifically provided herein or required by provision of law which
may not be waived, hereby waives any and all notices or demands with respect to
any exercise by the Mortgagee of any rights or powers which it may have or to
which it may be entitled with respect to the Collateral.

     4.3.6. The Mortgagor hereby irrevocably constitutes and appoints the
Mortgagee as the true and lawful attorney-in-fact of the Mortgagor, which
appointment is coupled with an interest, with full power of substitution, to
proceed from time to time in the Mortgagor's name in any statutory or
non-statutory proceeding affecting the Mortgagor or any Collateral, and the
Mortgagee or its nominee may (i) execute and file proof of claim for the full
amount of any Collateral and vote such claims for the full amount thereof (A)
for or against any proposal or resolution, (B) for a trustee or trustees or for
a receiver or receivers or for a committee of creditors and/or (C) for the
acceptance or rejection of any proposed arrangement, plan of reorganization,
composition or extension, and the

Mortgagee or its nominee may receive any payment or distribution and give
acquittance therefor and may exchange or release Collateral; (ii) endorse any
draft or other instrument for the payment of money, execute releases and
negotiate and enter into settlements; and (iii) execute all such other documents
or instruments as may be necessary or expedient to be executed by the Mortgagor
for any of the purposes of this Mortgage; provided, however, that the power
provided for in this sentence may be exercised by the Mortgagee only while an
Event of Default is continuing. The Mortgagee shall have no duty to exercise any
of the aforesaid rights, privileges or options and shall not be responsible for
any failure to do so or delay in so doing.

     4.4. Remedies and Entry Upon Default.

     4.4.1. So long as no Event of Default shall have occurred and be
continuing, the Mortgagor shall have the right to collect (but not more than one
(1) month in advance) and retain all of the rents, gross receipts and other
payments, if any, from the Space Leases and from the Mortgaged Premises
generally, and the Mortgagee agrees that customary initial rent payments,
security deposits and reimbursements by a Space Tenant to the Mortgagor on
account of alterations made by the Mortgagor for the benefit of the Space Tenant
are permissible advance payments by the Space Tenant.

     4.4.2. Upon any Event of Default, the Mortgagee may, but shall not be
obligated to:

          (a) terminate the rights of the Mortgagor referred to in SECTION 4.3
     hereof and exercise all of the powers, rights and remedies provided for in
     SECTION 4.3 hereof, including those to be exercised only from and after an
     Event of Default;

          (b) at any time and from time to time, without notice to, or assent
     by, the Mortgagor or any other Person, but without affecting any of the
     Obligations, in the name of the Mortgagor or in the name of the Mortgagee,
     notify the account debtors and obligors on any or all of the Space Leases
     to make payment and performance directly to the Mortgagee, and demand,
     collect, receive, compound and give acquittance for the Space Leases or any
     part thereof; extend the time of payment and performance of, compromise or
     settle for cash, credit or otherwise, upon any terms and conditions, any of
     the Space Leases; endorse to the order of the Mortgagee checks, drafts or
     other orders

     or instruments for the payment of moneys payable to the Mortgagor which
     shall be issued in respect of any of the Space Leases; file any claims,
     commence, maintain or discontinue any actions, suits or other proceedings
     deemed by the Mortgagee necessary or advisable for the purpose of
     collecting upon or enforcing any of the Space Leases; and execute any
     instrument and do all other things deemed necessary and proper by the
     Mortgagee to protect and preserve and realize upon the Space Leases and/or
     the other rights contemplated hereby; the Mortgagor hereby irrevocably
     constitutes and appoints the Mortgagee as such the Mortgagor's lawful
     attorney-in-fact, coupled with an interest, and its agent for the foregoing
     purposes;

          (c) demand, collect, sue for, attach, levy, recover, receive,
     compromise and adjust, and make, execute and deliver receipts and releases
     for all Income that may then be or may thereafter become due, owing or
     payable with respect to the Premises or any part or parts thereof from any
     present or future lessees, tenants, subtenants or occupants thereof or from
     any present or future contract obligors; and/or

          (d) pay, in such order as the Mortgagee in its sole discretion shall
     determine, from and out of the Income collected in connection with the
     Premises and/or the Collateral or any part or parts thereof or from or out
     of any other funds (less the expense of collection, including reasonable
     attorneys' fees and disbursements), any taxes, assessments, water rates,
     sewer rates, or other government or other charges levied, assessed or
     imposed against the Premises or any part or part thereof, and also any and
     all other charges, costs and expenses which the Mortgagee deems necessary
     or advisable to pay in respect of the management or operation of the
     Premises, including, without limitation, the costs of insurance policies,
     repairs and alterations, commissions for renting the Premises or any part
     or parts thereof, legal expenses in enforcing claims, preparing papers or
     procuring any other services that may be required and any amounts payable
     under or pursuant to any Lease; all amounts so paid and expended shall be
     payable on demand, together with interest at the Involuntary Rate from the
     date incurred until paid, and be deemed to be included within the
     Obligations and secured by this Mortgage; the provisions of this ARTICLE
     and the rights given to the Mortgagee hereby shall inure to the benefit of
     the Mortgagee even though the Mortgagee does not enter and

     take possession of the Premises; any balance remaining after the
     indebtedness secured hereby and the other obligations of the Mortgagor
     under the Loan and Security Documents shall have been paid in full shall be
     turned over to the Person lawfully entitled thereto. Neither the entry upon
     and taking possession of the Mortgaged Premises, nor the collection and
     application of the rents, gross receipts or other charges thereof, nor any
     other action taken by the Mortgagee in connection therewith, shall cure or
     waive any default hereunder or waive or modify any notice thereof or notice
     of acceleration of the Note theretofore given by the Mortgagee.

     4.4.3. If an Event of Default shall have occurred and be continuing, a
notice in writing by the Mortgagee to the Space Tenants under the Space Leases
advising them that the Mortgagor has defaulted hereunder and requesting that all
future payments of rent, additional rent or other charges under the Space Leases
be made to the Mortgagee (or its agent) shall be construed as conclusive
authority to such Space Tenants that such payments are to be made to the
Mortgagee (or its agent). Each Space Tenant shall be fully protected in making
such payments to the Mortgagee (or its agent) and be given full credit against
its obligations under the applicable Space Lease to the extent of payments made
to the Mortgagee (or its agent) pursuant to any such notice; and the Mortgagor
hereby irrevocably constitutes and appoints the Mortgagee the attorney-in-fact
and agent of the Mortgagor, coupled with an interest, for the purpose of
endorsing the consent of the Mortgagor on any such notice.

     4.5. No Obligation of Mortgagee.

     4.5.1. The Mortgagee shall not be obligated to perform or discharge any
obligation of the Mortgagor as a result of the assignment hereby effected, and
the Mortgagor hereby agrees to indemnify and hold the Mortgagee harmless from
and against any and all liability, loss or damage which the Mortgagee may incur
by reason of any act of the Mortgagee under this Mortgage, other than as a
result of the Mortgagee's willful misconduct or gross negligence and other than
as a result of the Mortgagee's misconduct or negligence after the Mortgagee has
taken possession of the Premises. Should the Mortgagee (i) incur any such
liability, loss or damage by reason of this Mortgage and which is covered by the
foregoing indemnity, or in defense against any such claims or demands, or (ii)
perform any acts or covenants on the part of the Mortgagor 


                                     - 36 -

to be performed under the Space Leases, or (iii) pay for the account of the
Mortgagor (other than from Income or from funds delivered to the Mortgagee by
the Mortgagor to be held in trust for such purpose), any and all sums, costs and
expenses for the discharge of taxes, assessments, water rents or other liens
against the Collateral or any part thereof, or on account of insurance premiums
or repairs, and also any amounts and expenses necessary to perform any covenants
and conditions to be performed on the part of the Mortgagor under the Space
Leases, the amount thereof, including costs, expenses and reasonable attorneys'
fees, together with interest thereon at the Involuntary Rate from the date such
expenses were paid by the Mortgagee to the date of payment to the Mortgagee by
the Mortgagor, shall be included in the Obligations secured by this Mortgage,
and the Mortgagor shall reimburse the Mortgagee therefor upon demand.

     4.5.2. The acceptance by the Mortgagee of this Mortgage, with all the
rights, powers, privileges and authority so created, shall not at any time or in
any event obligate the Mortgagee to appear in or defend any action or proceeding
relating to the Collateral, or to take any action hereunder or thereunder, or to
expend any money or incur any expenses or perform or discharge any obligation,
duty or liability under the Collateral.


                                   ARTICLE V.

                Security Agreement Under Uniform Commercial Code

     5.1. This Mortgage shall constitute a security agreement within the meaning
of the Uniform Commercial Code of the State (the "Code"), and the Mortgagee
shall be deemed to be the "secured party" (as that term is defined in the Code).
The Mortgagor hereby grants to the Mortgagee, as additional collateral for the
obligations under the Note and the other Obligations secured hereby, a security
interest in and to all of the Mortgaged Premises which are considered or as
shall be determined to be personal property or "fixtures" (as defined in the
Code), including, without limitation, the Building Service Equipment, the
Furnishings, the Payments and Intangibles, all books, records, licenses and
certificates of the Mortgagor relating to the Mortgaged Premises, together with
all replacements thereof, substitutions therefor or additions thereto (said
property being sometimes hereinafter referred to as the "Personal Property").
The Mortgagor agrees that a security interest shall attach to the Personal
Property for the benefit of the 


                                     - 37 -

Mortgagee to secure the indebtedness evidenced by the Note and the other
Obligations secured by this Mortgage and all other sums and charges which may
become due hereunder, thereunder or under any of the other Security Documents.
The Mortgagor hereby authorizes the Mortgagee to file financing and continuation
statements with respect to the Personal Property without the signature of the
Mortgagor, if permitted by the Code. In any event the Mortgagor covenants to
execute such financing and continuation statements as the Mortgagee may
reasonably request. If an Event of Default shall occur and be continuing, the
Mortgagee, pursuant to the appropriate provisions of the Code, shall have the
option of proceeding as to both real and personal property in accordance with
its rights and remedies in respect of real property under this Mortgage and the
law of the State, in which event the default provisions of the Code shall not
apply. The Mortgagor agrees that, in the event the Mortgagee shall elect to
proceed with respect to the Personal Property separately from the real property,
unless a greater period shall then be mandated by the Code, five (5) days notice
of the sale of the Personal Property shall be reasonable notice. The expenses of
retaking, holding, preparing for sale and selling incurred by the Mortgagee
shall be assessed against the Mortgagor and shall include, but not be limited
to, the reasonable legal expenses incurred by Mortgagee. The Mortgagor agrees
that it will not remove or permit to be removed from the Mortgaged Premises any
of the Personal Property without the prior written consent of the Mortgagee
except as set forth in SECTION 2.7.2. All replacements, renewals and additions
to the Personal Property shall be and become immediately subject to the security
interest of this Mortgage and the provisions of this ARTICLE V. The Mortgagor
warrants and represents that all Personal Property now is free and clear of all
liens, encumbrances or security interests other than the Permitted Encumbrances,
and that all replacements of the Personal Property, substitutions therefor or
additions thereto, unless the Mortgagee otherwise consents, will be, free and
clear of liens, encumbrances or security interests of others.


                                   ARTICLE VI.

                         Events of Default and Remedies


     6.1. Events of Default. The whole of the outstanding Principal Amount (as
defined in the Note) and accrued interest evidenced by the Note shall, at the
option 


                                     - 38 -

of the Mortgagee, become due upon the happening of an Event of Default;
provided, however, that upon the occurrence of a default specified in SECTIONS
5.01(f) or 5.01(g) of the Loan Agreement, or upon the occurrence of any other
default specified in any Loan Document (as defined in the Loan Agreement) where
provision is made for acceleration to occur automatically as a consequence
thereof, all sums owing to the Mortgagee thereunder shall automatically become
immediately due and payable.

     6.2. Remedies.

     6.2.1. If an Event of Default shall occur and be continuing, the Mortgagee,
at its option, may:

          (1) by notice to the Mortgagor, declare the entire principal amount of
     the Note then outstanding and all accrued and unpaid interest thereon and
     all obligations of the Mortgagor to the Mortgagee to be immediately due and
     payable, and upon such declaration such principal and interest and all
     obligations of the Mortgagor to the Mortgagee shall become and be
     immediately due and payable, anything in the Note, the Loan Agreement or in
     this Mortgage or in any of the other Security Documents to the contrary
     notwithstanding;

          (2) during the continuance of any such Event of Default, Mortgagee
     personally, or by its agents or attorneys, may enter into and upon all or
     any part of the Premises, and each and every part thereof, and is hereby
     given a right and license and appointed Mortgagor's attorney-in-fact and
     exclusive agent to do so, and may exclude Mortgagor, its agents and
     servants wholly therefrom; and having and holding the same, may use,
     operate, manage and control the Mortgaged Premises and conduct the business
     thereof, either personally or by its superintendents, managers, agents,
     servants, attorneys or receivers; and upon every such entry, Mortgagee, at
     the expense of the Mortgaged Premises, from time to time, either by
     purchase, repairs or construction, may maintain and restore the Mortgaged
     Premises whereof it shall become possessed as aforesaid, may complete the
     construction of the Improvements and in the course of such completion may
     make such changes in the contemplated Improvements as it may deem desirable
     and may insure the same; and likewise, from time to time, at the expense of
     the Mortgaged Premises, Mortgagee may make all necessary or proper repairs,
     renewals and replacements and such useful alterations, additions,
     betterments and 

                                     - 39 -

<PAGE>



     improvements thereto and thereon as to it may seem advisable; and in every
     such case Mortgagee shall have the right to manage and operate the
     Mortgaged Premises and to carry on the business thereof and exercise all
     rights and powers of Mortgagor with respect thereto either in the name of
     Mortgagor or otherwise as it shall deem best; and Mortgagee shall be
     entitled to collect and receive the rents, income, issue and profits of the
     Mortgaged Premises, and every part thereof, all of which shall for all
     purposes constitute property of Mortgagor; and in furtherance of such right
     Mortgagee may collect the rents payable under all leases of the Mortgaged
     Premises directly from the lessees thereunder upon notice to each such
     lessee that an Event of Default exists hereunder accompanied by a demand on
     such lessee for the payment to Mortgagee of all rents due and to become due
     under its Space Lease, and Mortgagor FOR THE BENEFIT OF MORTGAGEE AND EACH
     SUCH SPACE TENANT hereby covenants and agrees that the Space Tenant shall
     be under no duty to question the accuracy of Mortgagee's statement of
     default and shall unequivocally be authorized to pay said rents to
     Mortgagee without regard to the truth of Mortgagee's statement of default
     and notwithstanding notices from Mortgagor disputing the existence of an
     Event of Default such that the payment of rent by the Space Tenant to
     Mortgagee pursuant to such a demand shall constitute performance in full of
     the Space Tenant's obligation under the Space Lease for the payment of
     rents by the Space Tenant to Mortgagor; and after deducting the expenses of
     conducting the business thereof and of all maintenance, repairs, renewals,
     replacements, alterations, additions, betterments and improvements and
     amounts necessary to pay for taxes, assessments, insurance and prior or
     other proper charges upon the Mortgaged Premises or any part thereof, as
     well as just and reasonable compensation for the services of Mortgagee and
     for all attorneys, counsel, agents, clerks, servants and other employees by
     it engaged and employed, Mortgagee shall apply the moneys arising as
     aforesaid as provided below.

          (3) with or without entry, personally or by its agents or attorneys,
     insofar as applicable, may:

               a. sell the Mortgaged Premises to the extent permitted and
          pursuant to the procedures provided by law, and all estate, right,
          title and interest, claim and demand

          therein, and right of redemption thereof, at one or more sales as an
          entity or in parcels or parts, and at such time and place upon such
          terms and after such notice thereof as may be required or permitted by
          law; or

               b. institute proceedings for the complete or partial foreclosure
          of this Mortgage; or

               c. take such steps to protect and enforce its rights whether by
          action, suit or proceeding in equity or at law for the specific
          performance of any covenant, condition or agreement in the Note or in
          the Loan Agreement or in this Mortgage, or in aid of the execution of
          any power herein granted, or for any foreclosure hereunder, or for the
          enforcement of any other appropriate legal or equitable remedy or
          otherwise as Mortgagee shall elect.

          (4) exercise any and all remedies available to a secured party under
     the UCC in such order and in such manner as the Mortgagee in its sole
     discretion may determine; provided, however, that the expenses of retaking,
     holding, preparing for sale or the like, shall include reasonable
     attorneys' fees and other expenses of the Mortgagee and be secured by this
     Mortgage;

          (5) exercise any or all of its other rights and remedies provided
     herein, in any of the Security Documents, or other document or agreement
     now or hereafter securing all or any portion of the Obligations secured
     hereby, or as provided by law, in such order of priority as the Mortgagee
     shall determine in its sole discretion.

     6.2.2. Mortgagee may adjourn from time to time any sale by it to be made
under or by virtue of this Mortgage by announcement at the time and place
appointed for such sale or for such adjourned sale or sales; and, except as
otherwise provided by any applicable provision of law, Mortgagee, without
further notice or publication, may make such sale at the time and place to which
the same shall be so adjourned.

     6.2.3. Upon the completion of any sale or sales made by Mortgagee under or
by virtue of this SECTION 6.2, Mortgagee, or an officer of any court empowered
to do

so, shall execute and deliver to the accepted purchaser or purchasers a good and
sufficient instrument or instruments conveying, assigning and transferring all
estate, right, title and interest in and to the property and rights sold.
Mortgagee is hereby irrevocably appointed the true and lawful attorney of
Mortgagor, in its name and stead, to make all necessary conveyances,
assignments, transfers and deliveries of the Mortgaged Premises and rights so
sold and for that purpose Mortgagee may execute all necessary instruments of
conveyance, assignment and transfer, and may substitute one or more persons with
like power, Mortgagor hereby ratifying and confirming all that its said attorney
or such substitute or substitutes shall lawfully do by virtue hereof.
Nevertheless, Mortgagor, if requested by Mortgagee, shall ratify and confirm any
such sale or sales by executing and delivering to Mortgagee or to such purchaser
or purchasers all such instruments as may be advisable, in the judgment of
Mortgagee, for the purpose, and as may be designated in such request. Any such
sale or sales made under or by virtue of this SECTION 6.2, whether made under
the power of sale herein granted or under or by virtue of judicial proceedings
or of a judgment or decree of foreclosure and sale, shall operate to divest all
the estate, right, title, interest, claim and demand whatsoever, whether at law
or in equity, of Mortgagor in and to the properties and rights so sold, and
shall be a perpetual bar both at law and in equity against Mortgagor and against
any and all persons claiming or who may claim the same, or any part thereof
from, through or under Mortgagor.

     6.2.4. In the event of any sale or sales made under or by virtue of this
SECTION 6.2 (whether made under the power of sale herein granted or under or by
virtue of judicial proceedings or of a judgment or decree of foreclosure and
sale), the entire principal of, and interest on, the Note, if not previously due
and payable, and all other sums required to be paid by Mortgagor pursuant to
this Mortgage, immediately thereupon shall, anything in the Note or in this
Mortgage to the contrary notwithstanding, become due and payable.

     6.2.5. The purchase money, proceeds or avails of any sale or sales made
under or by virtue of this SECTION 6.2, together with any other sums which then

     with interest at the Involuntary Rate on all advances made by Mortgagee,
     and of all taxes, assessments or other charges, except any taxes,

by Mortgagor pursuant to any provision of this Mortgage or the Note, and in
addition thereto such further amount as shall be sufficient to cover the costs

Mortgagee, its agents and counsel and any expenses incurred by Mortgagee
hereunder. In the event Mortgagor shall fail forthwith to pay such amounts upon
such demand, Mortgagee shall be entitled and empowered to institute such action
or proceedings at law or in equity as may be advised by its counsel for the
collection of the sums so due and unpaid, and may prosecute any such action or
proceedings to judgment or final decree, and may enforce any such judgment or
final decree against Mortgagor and collect, out of the property of Mortgagor
wherever situated, as well as out of the Mortgaged Premises, in any manner
provided by law, moneys adjudged or decreed to be payable.

     6.2.8. Mortgagee shall be entitled to recover judgment as aforesaid either
before, after or during the pendency of any proceedings for the enforcement of
the provisions of this Mortgage; and the right of Mortgagee to recover such
judgment shall not be affected by any entry or sale hereunder, or by the
exercise of any other right, power or remedy for the enforcement of the
provisions of this Mortgage, or the foreclosure of the lien hereof; and in the
event of a sale of the Mortgaged Premises and of the application of the proceeds
of sale, as in this Mortgage provided, to the payment of the debt hereby
secured, Mortgagee shall be entitled to enforce payment of, and to receive all
amounts then remaining due and unpaid upon, the Note, and to enforce payment of
all other charges, payments and costs due under this Mortgage, and shall be
entitled to recover judgment for any portion of the debt remaining unpaid, with
interest at the Involuntary Rate. In case of proceedings against Mortgagor in
insolvency or bankruptcy or any proceedings for its reorganization or involving
the liquidation of its assets, then Mortgagee shall be entitled to prove the
whole amount of principal and interest due upon the Note to the full amount
thereof, and all other payments, charges and costs due under this Mortgage and
the Note, without deducting therefrom any proceeds obtained from the sale of the
whole or any part of the Mortgaged Premises, provided, however, that in no case
shall Mortgagee receive a greater amount than such principal and interest and
such other payments, charges and costs from the aggregate amount of the proceeds
of the sale of the Mortgaged Premises and the distribution from the estate of
Mortgagor.

     6.2.9. No recovery of any judgment by Mortgagee and no levy of an execution
under any judgment upon the Mortgaged Premises or upon any other property of

remedies of

Mortgagee hereunder, but such liens, rights, powers and remedies of Mortgagee
shall continue unimpaired as before.

be applied by Mortgagee in accordance with the provisions of SECTION 6.2.5
hereof.

     6.2.11. After the happening of any Event of Default and immediately upon
the commencement of any action, suit or other legal proceedings by Mortgagee to
obtain judgment for the principal of, or interest on, the Note and other sums
required to be paid by Mortgagor pursuant to any provision of this Mortgage or
the Note, or of any other nature in aid of the enforcement of the Note or of
this Mortgage, Mortgagor will (a) waive the issuance and service of process and
enter its voluntary appearance in such action, suit or proceeding and (b) if
required by Mortgagee, consent to the appointment of a receiver or receivers of
all or part of the Mortgaged Premises and of any or all of the rents, issues and
profits of the Mortgaged Premises in respect thereof. After the happening of any
Event of Default and during its continuance, or upon the commencement of any
proceedings to foreclose this Mortgage or to enforce the specific performance
hereof or in aid thereof or upon the commencement of any other judicial
proceeding to enforce any right of Mortgagee, Mortgagee shall be entitled, as a
matter of right, if it shall so elect, without the giving of notice to any other
party and without regard to the adequacy or inadequacy of any security for the
indebtedness secured hereby, forthwith either before or after declaring the
unpaid principal of the Note to be due and payable, to the appointment of such a
receiver or receivers.

     6.2.12. Notwithstanding the appointment of any receiver, liquidator or
trustee of Mortgagor, or of any of its property, or of the Mortgaged Premises,
or any part thereof, Mortgagee shall be entitled to retain possession and
control of all property now or hereafter held under this Mortgage.

     6.2.13. Mortgagor will not at any time insist upon, or plead, or in any
manner whatever claim or take any benefit or advantage of any stay or extension
or moratorium law, any exemption from execution or sale of the Mortgaged
Premises or any part thereof, wherever enacted, now or at any time hereafter in
force, which may affect the covenants and terms of performance of this Mortgage,
nor claim, take or insist upon any benefit or advantage of any

Mortgaged Premises, or any part thereof, prior to any sale or sales thereof
which may be made pursuant to any provision herein, or pursuant to the decree,
judgment or order of any court of competent jurisdiction; nor, after any such
sale or sales, claim or exercise any right under any statute heretofore or
hereafter enacted to redeem the property so sold or any part thereof and
Mortgagor hereby expressly waives all benefit or advantage of any such law or
laws, and covenants not to hinder, delay or impede the execution of any power
herein granted or delegated to Mortgagee, but to suffer and permit the execution
of every power as though no such law or laws had been made or enacted.

     6.2.14. During the continuance of any Event of Default and pending the
exercise by Mortgagee of its right to exclude Mortgagor from all or any part of
the Premises, Mortgagor agrees to pay the fair and reasonable rental value for
the use and occupancy of the Premises or any portion thereof which are in its
possession for such period and, upon default of any such payment, will vacate
and surrender possession of the Premises to Mortgagee or to a receiver, if any,
and in default thereof may be evicted by any summary action or proceeding for
the recovery of possession of premises for non-payment of rent, however
designated.

     6.3. Sale; No Marshalling of Assets.

     6.3.1. In case of a foreclosure sale, all of the Mortgaged Premises may be
sold in one parcel even though the proceeds of such sale exceed or may exceed
the indebtedness secured hereby. The Mortgagee shall not be required to exercise
any rights under this Mortgage before proceeding against any other security,
shall not be required to proceed against other security before proceeding under
this Mortgage, and shall not be precluded from proceeding against any or all of
any security held by the Mortgagee for any or all of the indebtedness secured
hereby in any order or at the same time.

     6.3.2. The Mortgagor agrees, to the full extent that it may lawfully do so,
that in any foreclosure or other action brought by the Mortgagee to enforce this
Mortgage, it will not at any time insist upon or plead or in any way take
advantage of any appraisement, valuation, stay, marshalling of assets,
extension, redemption or moratorium law now or hereafter in force and effect so
as to prevent, hinder, delay or otherwise affect the enforcement of the

                                     - 46 -

provisions of this Mortgage or any rights or remedies the Mortgagee may have
hereunder or by law.

     6.3.3. If the Mortgagee shall elect to accelerate the indebtedness secured
hereby following the occurrence of an Event of Default, the Mortgagor, within
five (5) days after demand, will pay to the Mortgagee, or any receiver appointed
in connection with the foreclosure of this Mortgage, any and all amounts then
held as security deposits under all Space Leases; and the Mortgagee or such
receiver shall be deemed to indemnify the Mortgagor against all claims of
tenants in respect of the security deposits so paid following such demand.

     6.4. Legal Expenses of the Mortgagee.

     6.4.1. The Mortgagor will pay to the Mortgagee, on demand, all costs,
charges and expenses (including, without limitation, reasonable attorneys' fees

connection with any action or proceeding to foreclose this Mortgage or to
recover or collect all, or any portion of the indebtedness secured hereby; and
(ii) in connection with any modification or amendment or assignment of this
Mortgage or the other Security Documents, together with interest on each such
payment made by the Mortgagee at the Involuntary Rate from the date of the
Mortgagee's demand for such payment to the date of reimbursement by the
Mortgagor.

     6.4.2. If any action or proceeding be commenced in which the Mortgagee is
made a party, or in which it becomes necessary to defend or uphold the lien of
this Mortgage, all reasonable sums paid by the Mortgagee for the expense of any
litigation to prosecute or defend the title, rights and lien created by this
Mortgage (including, without limitation, reasonable attorneys' fees) shall be
paid by the Mortgagor, together with interest thereon at the Involuntary Rate
from the date of the Mortgagee's demand for such payment to the date of
reimbursement by the Mortgagor.

     6.5. Remedies Cumulative; No Waiver; Etc.

     6.5.1. No remedy in this Mortgage conferred upon or reserved to the
Mortgagee is intended to be exclusive of any other remedy or remedies, and each
and every such remedy shall be cumulative, and shall be in addition to every
other remedy given hereunder or now or hereafter existing at law or in equity.
No delay or omission by the Mortgagee in exercising any right or power 

                                     - 47 -

arising upon any Event of Default shall impair any such right or power, or shall
be construed to be a waiver of or acquiescence in any such Event of Default; and
every power and remedy given by this Mortgage to the Mortgagee may be exercised
from time to time as often as the Mortgagee may determine it is appropriate to
do so.

     6.5.2. A waiver in one or more instances of compliance with any of the
terms, covenants, conditions or provisions of the Note, the Loan Agreement or of
the Security Documents shall apply to the particular instance or instances and
at the particular time or times only, and no such waiver shall be deemed a
continuing waiver. In any event, no waiver shall be effective, or be asserted by
the Mortgagor as having been made, unless set forth in a writing signed by the
Mortgagee.

     6.5.3. The Mortgagor waives and renounces all homestead and similar
exemption rights with respect to the Mortgaged Premises provided for by the
Constitution and laws of the United States and of the State as against the
collection of the Security Documents, or any part thereof.

     6.6. No Merger. It is the intention of the parties to this Mortgage that if
the Mortgagee shall at any time hereafter acquire title to all or any portion of
the Mortgaged Premises, then, and until the indebtedness secured hereby has been
paid in full, the interest of the Mortgagee hereunder and the lien of this
Mortgage shall not merge or become merged in or with the estate and interest of
the Mortgagee, as the holder and owner of title to all or any portion of the
Mortgaged Premises and that, until such payment, the estate of the Mortgagee in
the Mortgaged Premises and the lien of this Mortgage and the interest of the
Mortgagee hereunder shall continue in full force and effect to the same extent
as if the Mortgagee had not acquired title to all or any portion of the
Mortgaged Premises.

without limiting any other provision of this Mortgage, and without waiving or
releasing the Mortgagor from any obligation or default hereunder, after giving
any notice to the Mortgagor required hereunder and after the passage of any
applicable cure periods (or without such notice in the event of an emergency),
the Mortgagee (or any receiver of the Mortgaged Premises) shall have the right,
but not the obligation, to make any such payment, or to perform any other act or
take any appropriate action, including, without limitation, entry on the
Mortgaged Premises and performance of work thereat, as it, in its sole
discretion, may deem necessary to cause such other term, covenant, condition or
obligation to be promptly performed or observed on behalf of the Mortgagor or to
protect the security of this Mortgage. All amounts advanced by, or on behalf of,
the Mortgagee in exercising its rights under this SECTION 7.3 (including, but

matter of convenience and for reference, and in no way define, limit, enlarge or
describe the scope or intent of this Mortgage or in any other way affect this

be construed as if such invalid, illegal or unenforceable provision had never
been included.

other Security Documents to the contrary notwithstanding, the Mortgagee shall
never be entitled to receive, collect or apply as interest on the principal
amount of the Note or any other of the obligations secured hereby any amount in
excess of the maximum rate of interest permitted to be charged by applicable
law. In the event the Mortgagee ever receives, collects or applies as interest
any such excess, the amount which would be excessive interest shall be applied
to the reduction of the principal amount of said obligations; and if said
principal amount shall have been paid in full, shall be remitted to the Person
lawfully entitled thereto. In determining whether or not the interest paid or
payable in any specific instance shall exceed the highest lawful rate, the
Mortgagor and the Mortgagee shall to the maximum extent permitted by applicable
law (i) characterize any non-principal payment as

     2.2. Warranty of Title. The Mortgagor warrants that, to the best of the
Mortgagor's knowledge (a) the Mortgaged Premises are free and clear of all liens
and encumbrances other than the Permitted Encumbrances; (b) it owns the Building

          (i) that the Mortgagor is lawfully seized and possessed of a fee in

provisions of SECTION 2.4.4. The Mortgagor will keep and maintain the Mortgaged
Premises, and every part thereof, free from all liens or lien notices, of
Persons supplying labor and/or materials in connection with any construction,
alteration, repair, improvement or replacement of the Improvements or of the
Building Service Equipment and Furnishings. If any such lien shall be filed
against the Mortgaged Premises, or any part thereof, the Mortgagor promptly
shall discharge the lien of record, by bonding or otherwise. The Mortgagor shall
exhibit to the Mortgagee, upon request, appropriate receipts or other
satisfactory evidence of the payment of the Impositions or any other item which
may, if not paid, give rise to a lien against the Mortgaged Premises.

     2.4. To Pay Impositions.

     2.4.1. The Mortgagor will pay or cause to be paid, as and when due and
payable, all Impositions levied upon the Mortgaged Premises or any part thereof,
together with all filing, registration or recording fees and all expenses
incident to the execution and acknowledgement of this Mortgage, any mortgage
supplemental hereto, and will pay all federal, state, county and municipal stamp
taxes and other taxes, duties, imposts, assessments and charges arising out of
or in connection with the execution and delivery of the Note, this Mortgage, any
mortgage supplemental hereto, or any instrument of further assurance. However,
if by law, any Imposition may at the option of the taxpayer be paid in
installments (whether or not interest shall accrue on the unpaid balance
thereof), the Mortgagor shall have the right to exercise such option and to pay
such Imposition, or cause it to be paid (together with any accrued interest on
the unpaid balance) in installments as they fall due and before any fine,
penalty, further interest or cost may be added thereto.

     2.4.2. If an Event of Default shall occur and be continuing, then upon
demand of the Mortgagee, the Mortgagor shall deposit with the Mortgagee a sum
which bears the same relation to the annual insurance premiums for all insurance
required by the terms hereof and real estate taxes and assessments assessed
against the Mortgaged Premises for the insurance period or tax year then in
effect, as the case may be, as the number of months elapsed as of the date of
such demand since the last preceding installment of said premiums or taxes or
assessments shall have become due and payable bears to twelve (12). For the
purpose of this computation, the month in which such last preceding installment
of premiums or real estate taxes or assessments became due and payable and the
month in which such demand is given shall be included and deemed to have
elapsed. On the



                                        9

first day of the month next succeeding the month in which such demand is given,
and thereafter on the first day of each and every month during the term of this
Mortgage, the Mortgagor shall deposit with the Mortgagee a sum equal to
one-twelfth of such insurance premiums and such taxes and assessments for the
then-current insurance period and tax year, so that as each installment of such
premiums and taxes and assessments shall become due and payable, the Mortgagor
shall have deposited with the Mortgagee a sum sufficient to pay the same. All
such deposits shall be received and held as part of such deposit by the
Mortgagee (all such deposits to be held in an account without interest thereon)
and shall be applied to the payment of each installment of such premiums and
taxes and assessments as they shall become due and payable. The Mortgagee shall,
upon demand, furnish evidence to the Mortgagor of the making of each such
payment. If the amount of such premiums and taxes and assessments has not been
definitely ascertained at the time when any such monthly deposits are required
to be made, the Mortgagor shall make such deposits based upon the amount of such
premiums and taxes and assessments for the preceding year, subject to adjustment
as and when the amount of such premiums and taxes and assessments are
ascertained. If at any time when any installment of such premiums and such taxes
and assessments becomes due and payable the Mortgagor shall not have deposited a
sum sufficient to pay the same, the Mortgagor shall, within five (5) days after
demand, deposit any deficiency with the Mortgagee. Upon payment in full of the
indebtedness evidenced by the Note, any remaining amount on deposit with the
Mortgagee shall be repaid to the Person lawfully entitled thereto. If an Event
of Default shall occur and be continuing, the Mortgagee may, at its option,
apply all or any portion of the amounts then on deposit with the Mortgagee
pursuant to this SECTION 2.4.2 first to the payment of any premiums, taxes or
assessments then due, and any remaining amounts may be applied to the payment of
the indebtedness. The Mortgagor shall deliver to the Mortgagee all insurance and
tax bills promptly following receipt during any period when such monthly
deposits are to be made with the Mortgagee.

     2.4.3. The Mortgagor will pay all taxes and other governmental charges
(including, without limitation, stamp taxes), except income or franchise taxes
or similar taxes based upon or measured by income, assessed by the United States
government or any state or local governmental authority and imposed on the
Mortgagee, its successors by reason of the ownership of this Mortgage or the
Note or the receipt of the interest or other sums payable thereunder or payable
by either the Mortgagor or the Mortgagee upon any increase in the indebtedness
secured hereby, or any modification, amendment, extension or

consolidation of this Mortgage. Without limiting the foregoing and subject to
the limitations set forth above, the Mortgagor will also pay the whole of any
tax imposed, directly or indirectly, on this Mortgage or the Note or the receipt
of any portion of the indebtedness in lieu of a tax on the Mortgaged Premises or
the Improvements and Building Service Equipment, whether by reason of (a) the
passage after the date of this Mortgage of any law of the State deducting from
the value of real property for the purposes of taxation any lien thereon; (b)
any change in the laws for the taxation of Mortgages or debts secured by
Mortgages for state or local purposes; (c) a change in the means of collection
of any such tax or otherwise; or (d) any tax, whether or not now existing,
assessed against, or withheld from, interest or other payments made by the
Mortgagor or assessed against this Mortgage and which are assessed or levied by
the government of any foreign nation or political subdivision thereof, provided
such tax liability shall not result from the ownership of this Mortgage by a
Person not a citizen of, or an entity not formed under the laws of, the United
States or any state. Within a reasonable time after payment of any such tax or
governmental charge, the Mortgagor will deliver to the Mortgagee satisfactory
proof of payment thereof, subject, however, to the right of the Mortgagor to
contest Impositions as hereinafter set forth. If the Mortgagor shall fail to pay
such tax or charge within fifteen (15) days after written notice, or if under
applicable law the Mortgagor's payment or agreement to pay the same shall be
unenforceable, the Mortgagee shall have the right to declare the entire unpaid
indebtedness and all accrued and unpaid interest thereon due and payable on a
date specified by the Mortgagee, but, in any event, not less than thirty (30)
days after written notice to the Mortgagor.

     2.4.4. The Mortgagor shall have the right to contest the amount or
validity, in whole or in part, of any Imposition, or to seek a reduction in the
valuation of the Mortgaged Premises, or any part thereof, as assessed for real
estate or personal property tax purposes by appropriate proceedings diligently
conducted in good faith, but only after payment of such Imposition, unless such
payment would operate as a bar to such contest or materially adversely interfere
with the prosecution thereof, in which event the Mortgagor may postpone or defer
payment of such Imposition (but not the payment of any monthly deposits pursuant
to SECTION 2.4.2 hereof); and upon request by the Mortgagor, the Mortgagee shall
postpone or defer payment of such Imposition; provided, however, that if at any
time the Mortgaged Premises, the Building Service Equipment, the Furnishings, or
any part thereof would, in the Mortgagee's reasonable judgment, by reason of
such postponement or deferment be in imminent danger of being forfeited or lost,



                                       11

or if the Mortgagee might be subjected to any civil or criminal liability or
other sanction, then the Mortgagor, on demand, shall immediately pay or cause to
be paid the amount so contested and unpaid, together with all interest and
penalties in connection therewith.

     2.4.5. The certificate, advice or bill of the appropriate official
designated by law to make or issue the same or to receive payment of any
Imposition indicating the nonpayment of such Imposition shall be prima facie
evidence that such Imposition is due and payable but unpaid at the time of the
making or issuance thereof.

     2.5. Insurance; Restoration Following Casualty.

     2.5.1. Until the indebtedness secured hereby is paid in full, the Mortgagor
shall at its own expense at all times maintain or cause to be maintained on all
of the Mortgaged Premises (a) comprehensive general liability insurance,
including umbrella liability insurance, covering all claims for bodily injury,
including death, and property damage occurring on, in or about the Mortgaged
Premises in an aggregate amount of not less than Five Million Dollars
($5,000,000) per occurrence, and a single limit of not less than Two Million
Dollars ($2,000,000) per person and per occurrence for personal injury, bodily
injury and property damage; the policy shall have no deductible or self insured
retention requirements; the policy limits of such insurance, if requested by the
Mortgagee, shall be increased from time to time to reflect what a reasonably
prudent owner or lessee of buildings or improvements similar in type and
locality to the Mortgaged Premises would carry; during any period of substantial
alterations or improvements in, on or to the Mortgaged Premises, the Mortgagor
will cause the comprehensive general liability insurance, including umbrella
liability insurance, endorsed to provide owners' and contractors' protective
liability coverage, including completed operations liability coverage; (b)
physical damage insurance (all risk non-reporting property insurance, including
earthquake insurance, with the Mortgagee named as loss payee), covering the
Mortgaged Premises for loss or damages resulting from the perils of fire,
lightning, earthquake, and such other risks and hazards as are provided under
the current standard "Extended Coverage Endorsement" and vandalism and malicious
mischief coverage, for the full replacement value of the Mortgaged Premises on a
stipulated and agreed-amount basis; (c) if the Mortgaged Premises is in an area
identified as a flood hazard area by the Secretary of Housing and Urban
Development, flood insurance, to the extent obtainable, in an amount equal to
the lesser of the full replacement value of the Mortgaged Premises or the
maximum amount available

under the Federal flood insurance program; (d) boiler and machinery insurance
covering all boilers, machinery, air conditioning, pressure vessels, and similar
type equipment commonly covered under a broad-form boiler and machinery policy,
in an amount satisfactory to the Mortgagee; (e) insurance against such other
risks of damage, hazards, casualties and contingencies in such amounts as the
Mortgagee shall from time to time reasonably require, provided that insurance
against such other risks, hazards, casualties or contingencies shall then be
commonly carried by prudent owners or lessees of building or improvements in the
locality similar in character, construction, use and occupancy to the
Improvements, Building Service Equipment and Furnishings on, or constituting a
part of, the Mortgaged Premises; and (f) loss of rents/business interruption
coverage in an amount sufficient to pay all Impositions, insurance premiums,
interest and principal installments and all other amounts due under the Note and
the Loan Agreement and the normal operating expenses of the Mortgaged Premises,
all for a period of one (1) year. Furthermore, the Mortgagee reserves the right
to require additional insurance and/or higher policy limits than heretofore
specified if such additional insurance and/or higher policy limits are
commercially reasonable for similar properties, which right may be exercised by
written notice to the Mortgagor, and, as soon thereafter as practicable, but in
any event within thirty (30) days of the receipt thereof, the Mortgagor agrees
to obtain insurance coverage complying with such notice. The proceeds of all
such insurance (except the insurance specified in SECTION 2.5.1(a)) shall be
paid solely to the Mortgagee and be held, applied or disbursed by the Mortgagee
as provided in SECTIONS 2.5.7 and 2.5.8.

     2.5.2. All insurance required in SECTION 2.5.1 shall be evidenced by valid
and enforceable policies, in form and substance as shall be required by the
Mortgagee from time to time, and issued by and distributed among insurers of
recognized responsibility having an A.M. Best's Guide of A:XII or better, a
financial size category of Class XI or above, and the total limit of liability
shall not exceed ten percent (10%) of the total policyholders' surplus. Such
insurers shall be authorized to do business in the State and in all other
respects shall be reasonably satisfactory to the Mortgagee. The originals of all
such policies, or duplicate copies or certificates thereof, shall be delivered
to the Mortgagee concurrently with the execution and delivery of this Mortgage.
Thereafter, all renewal or replacement policies, or duplicate copies or
certificates thereof, shall be delivered to the Mortgagee not less than thirty
(30) days prior to the expiration date of the policy or policies to be renewed
or replaced, in each case accompanied by evidence reasonably satisfactory to the

Mortgagee that all premiums currently payable with respect to such policies have
been paid in full by or at the direction of the Mortgagor.

     2.5.3. All such insurance policies shall (a) except for any liability
policy required hereunder, contain a standard noncontributory form of mortgagee
clause (in favor of and entitling the Mortgagee to collect any and all proceeds
payable under such insurance), as well as a standard waiver of subrogation
endorsement, all to be in form and substance reasonably satisfactory to the
Mortgagee; (b) provide that such policies may not be cancelled or amended
without at least thirty (30) days prior written notice to the Mortgagee; and (c)
provide that no act, omission or negligence of the Mortgagor, or its agents,
servants or employees, or of any Space Tenant under any Space Lease, which might
otherwise result in a forfeiture of such insurance or any part thereof, shall in
any way affect the validity or enforceability of such insurance insofar as the
Mortgagee is concerned. The Mortgagor shall not carry separate insurance,
concurrent in kind or form or contributing in the event of loss with any
insurance required under this SECTION 2.5. All losses under such insurance
policies shall be adjusted by the Mortgagor in the case of any single instance
of such damage or destruction not exceeding $200,000, by the Mortgagor and the
Mortgagee in the case of any such single instance of damage or destruction
exceeding such amount, provided that in no event shall the Mortgagor approve or
consent to any final adjustment in any amount exceeding the amount specified
above in this sentence without obtaining the Mortgagee's prior approval (which
approval shall not be unreasonably withheld) of the amount of such adjustment,
and solely by the Mortgagee in the case when an Event of Default exists and is
continuing.

     2.5.4. The Mortgagor, at its expense, will furnish to the Mortgagee, within
ninety (90) days after written demand, but in no event, except for reasonable
cause, more frequently than annually, proof of the then full replacement value
of each of the Improvements and the Building Service Equipment and Furnishings
therein, such proof to be by appraisals reasonably satisfactory in form and
substance to the Mortgagee and prepared by an appraiser (who may be an appraiser
for the insurance company insuring such property) designated and paid for by the
Mortgagor and approved by the Mortgagee, which approval shall not be
unreasonably withheld or delayed.

     2.5.5. If the Mortgagee shall, by any means, acquire the title or estate of
the Mortgagor in or to any portion of the Mortgaged Premises, it shall thereupon



                                       14

become the sole and absolute owner of all insurance policies affecting such
portion of the Mortgaged Premises held by, or required hereunder to be delivered
to, the Mortgagee, with the sole right to collect and retain all unearned
premiums thereon; and the Mortgagor shall be entitled only to a credit in
reduction of the then outstanding indebtedness in the amount of the short rate
cancellation refund, when and if received by Mortgagee. The Mortgagor agrees,
immediately upon demand, to execute and deliver such assignments or other
authorizations or instruments as may, in the reasonable opinion of the
Mortgagee, be reasonably necessary or desirable to effectuate any of the
provisions of this SECTION 2.5.5.

     2.5.6. If any of the Improvements, Building Service Equipment or
Furnishings shall be damaged or destroyed, in whole or in part, by fire or other
casualty, the Mortgagor shall give prompt notice thereof to the Mortgagee, and,
without regard to the availability or adequacy of insurance proceeds, shall
promptly following receipt of any insurance proceeds or the date when any such
proceeds are made available to the Mortgagor in accordance with the terms
hereof, commence to restore, replace, rebuild or alter the same as nearly as
possible to the condition, character and value thereof existing immediately
prior to such damage or destruction. Any insurance proceeds in respect of such
damage or destruction, or any Award (as defined in SECTION 3.2) for a partial
taking which is not a substantial or total taking, as such terms are referred to
in ARTICLE III hereof, at the option of the Mortgagee, may either (i) be applied
as a prepayment of the unpaid balance of the principal of the Note and of
accrued and unpaid interest thereon and as a payment of any other sums due and
owing under the Note, the Loan Agreement and the Security Documents, or (ii) be
made available to pay or reimburse costs incurred for restoration, replacement
or rebuilding necessitated as a result of such damage or destruction, or as a
result of such taking, as the case may be, or (iii) be used for any other
purpose or object deemed appropriate by the Mortgagee in connection with the
Mortgaged Premises, provided, however, that the Mortgagee may not elect either
option (i) or (iii) above if, and for so long as all of the following conditions
(collectively, the "Insurance or Award Conditions" have been and remain
satisfied: (a) no Event of Default has occurred and is continuing or would occur
as a result of such casualty or taking and no event has occurred that with the
passage of time or the giving of notice, or both, would constitute an Event of
Default; (b) the balance of the insurance proceeds or such Award either
initially paid to the Mortgagee or deposited with the Depository (as hereinafter
defined) or remaining from time to time, shall be sufficient, in the Mortgagee's
reasonable judgment, to



                                       15

complete the restoration, replacement or rebuilding, or the Mortgagor shall have
deposited such sufficient funds with the Mortgagee or the Depository; and (c)
the Mortgagee determines, in its reasonable discretion, that (i) the Loan to
Value Ratio (as defined in the Loan Agreement, and taking into consideration the
value of all of the Projects, as defined in the Loan Agreement) is not greater
than 55%, and (ii) the Debt Service Coverage Ratio (as defined in the Loan
Agreement, and taking into consideration the loss of income resulting from such
damage or destruction as projected by the Mortgagee in its reasonable
discretion) is not less than 1.40:1.0. Notwithstanding the foregoing, if an
event has occurred and is continuing that with the passage of time or the giving
of notice, or both, would constitute an Event of Default but the same has not
yet matured into an Event of Default, then, if the conditions set forth in the
foregoing clauses (b) and (c) have been or will be, in the Mortgagee's
reasonable judgment, satisfied, the Mortgagee shall not elect either option (i)
or (iii) unless such event shall have matured into an Event of Default and,
unless and until such event shall have so matured into an Event of Default or
such event has been cured or shall otherwise cease to exist, the Mortgagee (or
the Depository) shall not release any such insurance proceeds or Award and the
same shall be held until an Event of Default occurs or the Default has been
cured or shall otherwise cease to exist.

     2.5.7. Any such insurance proceeds (other than the proceeds of the rent
insurance policy, which shall be paid as provided in SECTION 2.5.8 below) or
Award which are to be applied to restoration, replacement or rebuilding of the
Mortgaged Premises shall, after payment or reimbursement to the Mortgagee of all
reasonable costs and expenses of the Mortgagee in collecting such proceeds or
Award, be applied upon satisfaction of the following provisions and conditions:

          (a) If the damage be of such nature as to require the Mortgagor to
     construct a replacement for, or to alter in any material or substantial
     way, the damaged or destroyed items, the Mortgagor shall, before commencing
     any such work, submit copies of the plans and specifications therefor to
     the Mortgagee for the Mortgagee's approval, such approval to not be
     unreasonably withheld or delayed.

          (b) If after payment or reimbursement to the Mortgagee of all costs
     and expenses of the Mortgagee in collecting such insurance proceeds or
     Award, the aggregate insurance proceeds or Award received by reason of any
     single instance of such damage or destruction or condemnation, as the case
     may

     be, shall be $200,000 or less such insurance proceeds or Award shall be
     paid to the Mortgagor, which shall hold all amounts so received in trust
     for application first to pay the entire cost of restoring, repairing,
     rebuilding or replacing the damaged or destroyed items, before any portion
     of such proceeds may be used or applied for any other purpose. If the
     aggregate net insurance proceeds or Award by reason of any single instance
     of such damage or destruction or condemnation, as the case may be, shall be
     more than $200,000 such sums shall be held and disbursed by Fleet Bank,
     National Association or, if this Mortgage is held by another financial
     institution, by such financial institution or, if this Mortgage is not held
     by a financial institution, by a financial institution selected by the then
     Mortgagee (the holder of such monies, the "Depository") in accordance with
     the following provisions of this SECTION 2.5.7.

          (c) The Mortgagee shall have received as to each such disbursement a
     certificate of the Mortgagor (i) requesting the payment of a specified
     amount of such insurance or condemnation proceeds; (ii) describing in
     reasonable detail the work and materials applied to the restoration,
     replacement or rebuilding of the damaged, destroyed or taken Improvement,
     or Building Service Equipment and/or Furnishings located therein, since the
     date of the last such certificate; (iii) stating that the requested amount
     does not exceed the cost of such work and materials; and (iv) stating that
     a request for payment for such work and materials has not previously been
     made, accompanied by:

               1. a certificate of an independent engineer or architect
          designated by the Mortgagor, who shall have been approved in writing
          by the Mortgagee (such approval not to be unreasonably withheld),
          stating (i) that the work and materials described in the accompanying
          certificate of the Mortgagor were satisfactorily performed and
          furnished and were necessary, appropriate or desirable to the
          restoration, replacement or rebuilding of the damaged, destroyed or
          taken Improvement, or Building Service Equipment and/or Furnishings;
          (ii) that the amount specified in such certificate of the Mortgagor
          does not exceed the reasonable cost of such work and materials; and
          (iii) the additional amount, if any, required to complete the
          restoration, replacement or rebuilding of the damaged, destroyed or
          taken Improvement, Building Service Equipment and/or Furnishings; and



                                       17

               2. evidence reasonably satisfactory to the Mortgagee (i) that
          there exists no filed or recorded lien, or lien notice, or encumbrance
          or charge in respect of all or any part of the Mortgaged Premises that
          is prior to or on a parity with the lien of this Mortgage, except as
          may be permitted in the Permitted Encumbrances; (ii) that neither the
          Mortgaged Premises nor any part thereof is subject to any recorded or
          filed mechanic's, laborer's, materialman's or any similar lien,
          encumbrance or charge; and (iii) that none of the Building Service
          Equipment and Furnishings provided in connection with such
          restoration, replacement or rebuilding is subject to any security
          interest other than in favor of the Mortgagee.

     Upon satisfaction of the conditions set forth herein, the Mortgagee shall
pay to the Mortgagor the amount of such insurance or condemnation proceeds
requested in such certificate of the Mortgagor or consent to the Depository's
payment thereof, as the case may be; provided, however, that in no event shall
the balance of insurance or condemnation proceeds held by the Mortgagee and the
Depository be reduced below the amount specified in such certificate of the
independent engineer or architect as the amount required to complete the
restoration, replacement or rebuilding of the damaged, destroyed or taken
Improvement, Building Service Equipment and/or Furnishings. Each such payment,
whether made by the Mortgagee or the Depository, shall be held by the Mortgagor
in trust and shall be used solely for the payment of the cost of the work and
materials described in the certificate of the Mortgagor, or if such cost or any
part thereof has theretofore been paid by the Mortgagor out of its own funds,
then for the reimbursement to the Mortgagor of any such cost or part thereof
paid by it. Any balance of insurance or condemnation proceeds held by the
Mortgagee after the completion of the restoration, replacement or rebuilding and
payment of all costs incurred in connection therewith, to be evidenced by a
certificate to such effect of such independent engineer or architect delivered
to the Mortgagee, shall, if no Event of Default shall have occurred and be
continuing, be released to the Person lawfully entitled thereto. Notwithstanding
the foregoing, if the Mortgagor needs to make deposits with or payments to
contractors prior to the work being performed, if the Mortgagee is otherwise
obligated to allow funds to be used to rebuild or restore, the Mortgagee agrees
that it will not unreasonably withhold or delay its consent to the 




                                       18

Mortgagor's request that such deposits or advances payments be allowed.

     2.5.8. All proceeds of rent insurance payable as a result of the occurrence
of any fire or other casualty which affects the Mortgaged Premises, or any part
thereof, shall be paid to the Mortgagee or, if the Mortgagee is not a financial
institution, the Depository. The Mortgagee or the Depository, as the case may
be, if it shall receive such proceeds, shall hold such proceeds in trust if
permitted under law, and in an account bearing interest (payable to or for
account of the Mortgagor), and shall apply or cause such proceeds (including any
net interest thereon) to be applied to the payment of those items referred to in
SECTION 2.5.1(f) which become, and as they become, due and payable from and
after the date of the occurrence of such damage or loss, until the completion of
the necessary restoration or replacement by the Mortgagor or until the
exhaustion of such proceeds (including any interest thereon), whichever first
occurs. Upon completion of such restoration or replacement, any balance of such
rent insurance proceeds, together with the interest thereon, if any, not
theretofore applied as provided herein, in the hands of the Mortgagee or the
Depository, as the case may be, shall, provided that no Event of Default shall
have occurred and be continuing, be paid to the Person lawfully entitled
thereto.

     2.5.9. Nothing in this SECTION 2.5 contained shall (i) relieve the
Mortgagor of its duty to repair, restore, rebuild or replace the Improvements,
Building Service Equipment and/or Furnishings following damage or destruction by
fire or other casualty or taking in the event that no Award or an inadequate
Award or that no or inadequate proceeds of insurance are available to defray the
cost of such repairing, restoring, rebuilding or replacement (provided, however,
the Mortgagor shall be permitted to receive the insurance proceeds upon
satisfaction of the conditions set forth herein provided, in addition, that all
of the Insurance or Award Conditions have been and remain satisfied), or (ii)
relieve the Mortgagor of its obligation to pay principal and interest and to
make all other payments required by the Note, the Loan Agreement and this
Mortgage subsequent to the occurrence of any fire or other casualty, or taking,
except if, and to the extent that, any proceeds of rent insurance are applied by
the Mortgagee in accordance with SECTION 2.5.8 to such required payments.

     2.5.10. If, while any insurance proceeds or Award is being held by the
Mortgagee or the Depository, an Event of Default shall occur and be continuing,
the Mortgagee shall be entitled to receive and apply all such 




                                       19

insurance proceeds or Award in reduction of the indebtedness and other
obligations secured by this Mortgage, in such order and respective amounts, as
the Mortgagee in its discretion shall determine.

     2.6. To Comply with Laws.

     2.6.1. The Mortgagor, at its own expense, will promptly cure all violations
of law affecting the Mortgaged Premises, or any part thereof, and/or the use and
operation thereof and will promptly comply, or cause to be complied with, all
present and future Legal Requirements. However, the Mortgagor shall have the
right, after prior notice to the Mortgagee, to contest by appropriate legal
proceedings, diligently conducted in good faith, the validity or application of
any Legal Requirement if and so long as the Mortgagor shall promptly furnish to
the Mortgagee a certificate to such effect showing the steps taken to comply
with such provisions, provided that:

          (a) if by the terms of any such Legal Requirement, compliance
     therewith pending the prosecution of any such proceeding may be delayed
     legally without incurring any lien, charge or liability of any kind against
     the Mortgaged Premises, or any part thereof, and without subjecting the
     Mortgagor or the Mortgagee to any liability, civil or criminal, for failure
     so to comply therewith, the Mortgagor may delay compliance therewith until
     the final determination of any such proceeding; and

          (b) if any lien, charge or civil liability would be incurred by reason
     of any such delay, the Mortgagor nevertheless, on the prior written consent
     of the Mortgagee, such consent not to be unreasonably withheld, may contest
     and delay compliance with the Legal Requirement, provided that such delay
     would not subject the Mortgagee to criminal liability and the Mortgagor (i)
     furnishes to the Mortgagee security reasonably satisfactory to the
     Mortgagee against loss or injury by reason of such contest or delay and
     (ii) prosecutes the contest with due diligence.

     2.6.2. Notwithstanding the provisions of SECTION 2.6.1, if any delay in
compliance with any Legal Requirement shall, in the reasonable judgment of the
Mortgagee, place all or any part of the Mortgaged Premises in imminent danger of
being forfeited or lost, the Mortgagor shall, upon written notice from the
Mortgagee, immediately comply with such Legal Requirement.




                                       20

FRK11497.A15

<PAGE>



     2.6.3. The Mortgagor will use and permit the use of the Mortgaged Premises
only in accordance with the material requirements of any applicable licenses and
permits issued by Governmental Authorities.

     2.6.4. The Mortgagor will procure, pay for and maintain (or cause to be
procured, paid and maintained) all permits, licenses and other authorizations
required to be procured and maintained by the owners and operators of the
Mortgaged Premises for any then use of all or any part of the Mortgaged Premises
then being made and for the lawful and proper operation and maintenance thereof.

     2.7. Limitation on Alterations and Demolition.

     2.7.1. The Mortgagor shall not voluntarily demolish, replace or alter the
Mortgaged Premises, or any part thereof, or voluntarily make any addition
thereto, or voluntarily construct any additional improvements thereon, or suffer
any of the same to occur, whether structural or otherwise (collectively,
"change"), without the prior written consent of the Mortgagee, which consent
shall not be unreasonably withheld or delayed; provided, however, that if no
Event of Default is continuing and such change involves an estimated cost of
less than $100,000 and is non-structural or if no Event of Default is continuing
and such change is non-structural and is being made to prepare space for a Space
Tenant pursuant to a Space Lease entered into in accordance with the Loan
Agreement, then, in either of such events, the Mortgagee's consent shall not be
required; provided, further, however, that if any such change is required by
law, the Mortgagor may make such change with the prior written consent of the
Mortgagee, which consent the Mortgagee will not unreasonably withhold or delay.
As a condition to any consent under this SECTION 2.7.1, the Mortgagee may
require (a) that plans and specifications for the proposed work, prepared by a
reputable architect reasonably satisfactory to the Mortgagee, be submitted to
the Mortgagee for approval, and (b) that the Mortgagor obtain a payment and
performance bond or other security reasonably satisfactory to the Mortgagee in
form and amount reasonably satisfactory to the Mortgagee from the contractor or
subcontractor performing the work unless such work amounts to less than $200,000
in aggregate total cost. All work performed by or on behalf of the Mortgagor
shall be completed with all reasonable diligence and continuity, in a good and
workmanlike manner, and in compliance with all applicable Legal Requirements.
Unless, and to the extent that, the provisions of SECTION 2.7.2 be applicable,
no Building Service Equipment or Furnishings shall be removed from the Mortgaged
Premises during the course of any such work without prior notification to the
Mortgagee and unless 




                                       21

<PAGE>



provision is made for return or replacement on or prior to the completion of the
work. The provisions of this SECTION 2.7.1. shall apply to any change made or
required to be made by the Mortgagor in the course of complying with any other
of the provisions of this Mortgage. A duplicate set of all plans and
specifications required to be filed with any Governmental Authority prior to, or
at any time in connection with, any such alteration, demolition or new
construction shall be furnished to the Mortgagee. The Mortgagor will pay on
demand the reasonable expenses incurred by the Mortgagee in the review of plans
and specifications provided for in this Mortgage.

     2.7.2. The Mortgagor shall have the right, at any time and from time to
time, to remove and dispose of any item of Building Service Equipment or
Furnishings which may have become obsolete or unfit for use or which is no
longer useful in the operation of the Improvements, provided that the Mortgagor
promptly replaces such item with other Building Service Equipment or
Furnishings, free of superior title, liens or claims (other than in favor of the
Mortgagee) unless consent of the Mortgagee is first obtained, not necessarily of
the same character but of at least equal quality, value and usefulness in
connection with the operation and maintenance of the Mortgaged Premises,
provided, further, however, no removal of any item of Building Service Equipment
or Furnishings then having a fair market value of $50,000 or more shall be made
without the prior written consent of the Mortgagee, which consent will not be
unreasonably withheld or delayed. However, if by reason of technological or
other developments in the operation and maintenance of buildings and other
improvements of the general character of the Improvements or a change in the use
of the Mortgaged Premises or any part thereof, no replacement of the Building
Service Equipment or Furnishings so removed would be necessary or desirable for
the proper operation or maintenance of the Improvements, the Mortgagor shall not
be required to replace the item so removed.

     2.8. Limitation on Disposition of the Mortgaged Premises.

     2.8.1. Except as expressly set forth in this Mortgage or the Loan Agreement
(including, without limitation, SECTIONS 5.01 and 6.21 of the Loan Agreement),
the Mortgagor shall not directly or indirectly sell, assign, mortgage, alienate,
pledge or otherwise transfer or further encumber the Mortgaged Premises or any
part thereof or any interest therein or in any of the rents, profits or income
generated thereby, whether voluntarily, involuntarily, by operation of law or
otherwise, or lease all or any portion 




                                       22

thereof or an undivided interest therein, without the prior written consent of
the Mortgagee. The foregoing events are hereinafter referred as a "Transfer".
Any Transfer without prior written the consent of the Mortgagee is an Event of
Default.

     2.8.2. If there shall be a violation of the terms and provisions of SECTION
2.8.1, whether by the Mortgagor or any other person, in addition to all other
rights and remedies available to the Mortgagee under this Mortgage, the
Mortgagee shall have the option, by the giving of notice to the Mortgagor, of
declaring the entire unpaid principal balance of the Note, together with all
accrued and unpaid interest and all other sums and charges evidenced thereby or
payable pursuant to the Loan Agreement, immediately due and payable.

     2.9. Maintenance of Mortgaged Premises; Covenant Against Waste; Inspection
by the Mortgagee. The Mortgagor will not commit or permit waste on the Mortgaged
Premises and, at its expense, will keep and maintain the Improvements, the
Building Service Equipment and Furnishings in its (or their) present state of
repair and condition, reasonable wear and tear excepted, and, if improved, in
such improved state of repair and condition, reasonable wear and tear excepted;
provided, that this shall not limit the Mortgagor's other obligations hereunder,
such as compliance with laws. The Mortgagor shall do or cause to be done all
maintenance and make or cause to be made all repairs as may be required by the
landlord under any Space Lease. The Mortgagor will neither do nor permit to be
done anything to the Mortgaged Premises that may materially impair the value
thereof or which may violate any covenant, condition or restriction affecting
the Mortgaged Premises, or any part thereof, or which would effect any material
change therein or in the condition thereof that would increase the danger of
fire or other hazard arising out of the operation of the Mortgaged Premises.
Subject to the rights of Space Tenants, the Mortgagee, and its representatives
and agents, may enter and inspect the Mortgaged Premises at any time after
reasonable notice (which may be oral) during usual business hours, and the
Mortgagor shall, within thirty (30) days after demand by the Mortgagee (or
immediately upon demand in case of emergency), make such repairs, replacements,
renewals or additions, or perform such items of maintenance, to the Mortgaged
Premises as the Mortgagee may reasonably require in order to cause the Mortgaged
Premises to comply with the standards established in this SECTION 2.9.

     2.10. To Furnish Certificates; Other Reporting Requirements.

     2.10.1. The Mortgagor will, at its own expense, deliver to the Mortgagee,
within fifteen (15) days after written request, but no more frequently than once
per six (6) month period, a written statement executed by the Mortgagor, in
recordable form, setting forth to the best of the Mortgagor's knowledge, the
amount then unpaid upon the Note and secured by this Mortgage and stating
whether any offsets or defenses exist against the indebtedness; and, if any such
offsets or defenses are alleged to exist, then the factual basis and amount of
such claimed offsets or defenses.

     2.10.2. The Mortgagor will, if requested by the Mortgagee, deliver to the
Mortgagee a certificate of an officer of the general partner of the Mortgagor or
of such general partner's general partner, to the effect that he is familiar
with this Mortgage and the other Security Documents, has reviewed the affairs of
the Mortgagor, and to the best of his knowledge and belief there exists no Event
of Default and no act or event has occurred or exists which with notice or lapse
of time or both could become such an Event of Default, or if any such event or
Event of Default exists, specifying it and what action the Mortgagor is taking
to cause it to be remedied.

     2.11. After-Acquired Property. All right, title and interest of the
Mortgagor in and to all improvements, betterments, renewals, substitutes and
replacements of, and all additions and appurtenances to, the Mortgaged Premises
hereafter acquired, constructed, assembled or placed on the Mortgaged Premises,
immediately upon such acquisition, construction, assembly or placement, as the
case may be, and in each such case without any further mortgage, conveyance or
assignment or other act of the Mortgagor, shall become subject to the lien of
this Mortgage as fully and completely, and with the same effect, as though now
owned by the Mortgagor and specifically described in the granting clauses
hereof; and at any time and from time to time the Mortgagor, on demand, will
execute, acknowledge and deliver to the Mortgagee any and all such further
assurances, mortgages, conveyances or assignments as the Mortgagee may
reasonably require to further evidence, confirm and perfect the provisions of
this SECTION 2.11.

     2.12. Further Assurances. The Mortgagor shall, at its sole cost and without
expense to the Mortgagee, on demand, do, execute, acknowledge and deliver all
and every such further acts, deeds, conveyances, mortgages, assignments, notices
of assignment, transfers and assurances as

the Mortgagee shall from time to time reasonably require for better assuring,
conveying, assigning, transferring and confirming unto the Mortgagee the
property and rights hereby mortgaged or assigned or intended now or hereafter so
to be, or which the Mortgagor may be or may hereafter become bound to convey,
mortgage or assign to the Mortgagee, or for carrying out the intention or
facilitating the performance of the terms of this Mortgage, or for filing,
registering or recording this Mortgage.

     2.13. Recorded Instruments. The Mortgagor will promptly perform and
observe, or cause to be performed and observed, all of the terms, covenants and
conditions of all instruments of record affecting the Mortgaged Premises (other
than non-consensual encumbrances hereafter affecting the Mortgaged Premises, the
validity or enforceability of which the Mortgagor is contesting in accordance
with this Mortgage) where non-compliance therewith affects the security of this
Mortgage or imposes any duty or obligation upon the Mortgagor or any Space
Tenant. The Mortgagor shall do or cause to be done all things reasonably
required to preserve intact and unimpaired and to renew any and all
rights-of-way, easements, grants, appurtenances, privileges, licenses,
franchises and other interests and rights in favor of or constituting any
portion of the Mortgaged Premises. The Mortgagor will not, without the prior
written consent of the Mortgagee, which consent shall not be unreasonably
withheld or delayed, initiate, join in or consent to any private restrictive
covenant or other public or private restriction as to the use of all or any
portion of the Mortgaged Premises. The Mortgagor will, however, comply with all
lawful restrictive covenants and zoning ordinances and other public or private
restrictions affecting all or any portion of the Mortgaged Premises.


                                  ARTICLE III.

                                  Condemnation


     3.1. Notice of Taking. The Mortgagor shall promptly notify the Mortgagee if
the Mortgagor receives notice of the institution of any proceeding or
negotiations for the taking of the Mortgaged Premises, or any part thereof,
whether for permanent or temporary use and occupancy in condemnation or by the
exercise of the power of eminent domain or by agreement of interested parties in
lieu of such condemnation (all the foregoing called a "taking"); shall keep the
Mortgagee currently advised, in detail, as to the status of such proceedings or
negotiations and will promptly give to the Mortgagee copies of all notices,

pleadings, judgments, determinations and other papers received or delivered by
the Mortgagor in connection with any such proceedings. The Mortgagee shall have
the right to appear and participate in such proceedings and may be represented
by counsel. The Mortgagor will not, without the Mortgagee's prior written
consent, which consent shall not be unreasonably withheld or delayed, enter into
any agreement for the taking of the Mortgaged Premises, or any part thereof,
with anyone authorized to acquire the Mortgaged Premises by eminent domain or in
condemnation.

     3.2. Condemnation Award. If the Mortgaged Premises shall be the subject of
a taking the Mortgagee shall be entitled to and shall receive the total of such
portion of all awards made that shall be allowed to the Mortgagor with respect
to all the right, title and interest of the Mortgagor in and to the Mortgaged
Premises (the award made in any total, partial or temporary taking is herein
called the "Award"), provided that the obligations of the Mortgagor to perform
the terms, covenants and conditions of this Mortgage, if any, affected by such
taking shall continue unimpaired until the actual vesting of title in such
proceeding and the actual receipt by the Mortgagee of the Mortgagor's share of
the entire Award resulting from such taking.

     3.3. Application of Award. The Mortgagee shall have the option of treating
a total taking or a substantial taking (as hereinafter defined) as an Event of
Default and of accelerating the entire indebtedness evidenced by the Note, in
which event it shall apply the Mortgagor's entire Award in reduction of such
indebtedness (including principal, interest and other sums secured hereby, in
such order as the Mortgagee may determine) and shall turn over any balance
remaining, if any, to the Person lawfully entitled thereto; or if the Mortgagee
shall not so elect to accelerate the indebtedness and apply the Award thereto,
then the total Award shall, regardless of amount, be deposited with the
Mortgagee or with the Depository, the Mortgagor hereby agreeing to elect that
such proceeds be held and disbursed by the Depository in accordance with
SECTIONS 2.5.6, 2.5.7, 2.5.8, 2.5.9 and 2.5.10 hereof for restoration required
to be made by the Mortgagor. If there be a partial taking, the net proceeds of
the Award shall be deposited with the Mortgagee and applied by the Mortgagee in
accordance with the provisions of SECTIONS 2.5.6, 2.5.7, 2.5.9 and 2.5.10. Any
Award remaining after the completion of such restoration, replacement or
rebuilding shall be applied in reduction of the indebtedness (including
principal, interest and other sums secured hereby) in such order as the
Mortgagee shall determine. A partial taking is substantial only if it materially
decreases the fair market

value of the Mortgaged Premises and the remainder of the Mortgaged Premises
cannot be restored to an economically viable whole.

     3.4. Temporary Taking. If any Award payable to the Mortgagor on account of
a taking for temporary use or occupancy is made in a lump sum or is payable
other than in equal monthly installments, the Mortgagor shall pay over such
Award to the Depository and such Award shall be applied to installments of
Impositions and of principal and interest and all other charges secured by this
Mortgage or due under the Note, the Loan Agreement, or the other Security
Documents as and when the same become due and payable. Any unapplied portion of
such Award held by the Depository when such taking ceases or expires (if no
Event of Default has then occurred and is continuing), or after the indebtedness
shall have been paid in full, shall be paid to the Person lawfully entitled
thereto.

     3.5. The Mortgagor's Obligation to Restore. If all available proceeds of
the Award are made available to the Mortgagor for restoration, replacement or
rebuilding pursuant hereto, the Mortgagor shall be obligated promptly to
restore, replace, rebuild or alter any Improvements or Building Service
Equipment affected by a taking so as to restore the Mortgaged Premises to an
economically viable whole, all without regard to the adequacy of the proceeds of
an Award, if any, made available to the Mortgagor.


                                   ARTICLE IV.

                   Assignment of Space Leases, Rents, Profits
                   and Other Income as Further Security, Etc.


     4.1. Assignment of Space Leases, Rents, Issues and Profits. Subject to the
Mortgagor's rights herein, including those set forth in SECTION 4.3.2 below, the
Mortgagor hereby absolutely, presently and irrevocably transfers, assigns and
sets over unto the Mortgagee all right, title and interest of the Mortgagor in
and to all Space Leases, if any, now or hereafter entered into with respect to
all or any part of the Mortgaged Premises, and all renewals, extensions,
subleases or assignments thereof, and all other occupancy agreements (written or
oral), by concession, license or otherwise, together with all of the rents,
income, receipts, revenues, issues and profits arising therefrom (the
"Collateral").

     4.2. The Mortgagor's Covenants Regarding Space Leases.

     4.2.1. Without the prior consent and approval of the Mortgagee in each
instance, the Mortgagor will not (a) assign, pledge, hypothecate or otherwise
encumber any of the Space Leases or the rents, income, issue and profits of the
Mortgaged Premises; or (b) enter into any Space Leases affecting the Mortgaged
Premises or any part thereof, unless such Space Lease is expressly subordinate
to the lien of this Mortgage and to any consolidation, extension, renewal,
recasting or refinancing hereof and the Space Lease provides, in substance, that
in the event of enforcement by the Mortgagee of the remedies provided for by law
or by this Mortgage, each Space Tenant shall, at the option of the Mortgagee,
enter into a agreement with the Mortgagee which shall provide, among other
things, that (i) such Space Tenant shall attorn to any person succeeding to the
interest of the Mortgagor as a result of such enforcement and shall recognize
such successor in interest as landlord under such Space Lease without change in
the terms or other provisions thereof, (ii) such successor shall not be bound by
any payment of rent or additional rent for more than one (1) month in advance or
any amendment or modification of any such Space Lease made without the
Mortgagee's written consent, and (iii) such successor shall not disturb the
possession of the Space Tenant provided certain conditions (as determined by the
Mortgagee) have been satisfied, including, without limitation, that the Space
Tenant shall not be in default under the terms of the Space Lease; or (c) enter
into any Space Leases without the prior written consent of the Mortgagee unless
permitted in SECTION 6.21 of the Loan Agreement.

     4.2.2. The Mortgagor further represents, warrants, covenants and agrees
that:

          (a) To the best of its knowledge, each Space Lease is (or, when
     executed, will be) a valid and legally enforceable obligation of the
     parties thereto, in full force and effect.

          (b) With respect to each Space Lease and the Space Tenant security
     deposits thereunder, any and/or all of such security deposits shall be held
     as required by the Space Lease but in no event in a manner other than that
     required by law.

          (c) The Mortgagor shall, at its sole cost and expense, keep, observe,
     perform and discharge, duly and punctually, all and singular the material
     obligations, terms, covenants, conditions, 


                                       28

FRK11497.A15

<PAGE>




     representations and warranties of each Space Lease on the part of the
     Mortgagor to be kept, observed, performed and discharged.

          (d) (i) Except as herein in this clause (i) expressly provided, the
     Mortgagor shall, at its sole cost and expense, maintain the Space Leases in
     full force and effect; the Mortgagor will not waive its rights under or
     materially modify, change, supplement, alter or amend ("Change"), nor shall
     the Mortgagor surrender (whether partial or total), terminate, cancel or
     subordinate, any of the Space Leases or enter into any Backlease (whether
     through an Affiliate or otherwise), and any such attempted Change,
     surrender, termination, cancellation or subordination or Backlease shall be
     void, unless, in each case, the prior written consent thereto of the
     Mortgagee shall have been obtained. Notwithstanding the foregoing, the
     Mortgagor may (x) terminate any Space Lease under 10,000 rentable square
     feet as a result of a default by the tenant under such Space Lease and (y)
     consent to any sublease or assignment of any Space Lease under 10,000
     rentable square feet provided (aa) such termination is being effected in
     the ordinary course of the Mortgagor's business, (bb) no Event of Default
     then exists and no event has occurred that with the passage of time or the
     giving of notice or both would constitute an Event of Default, and (cc) the
     Mortgagee determines, in its reasonable discretion, that upon the
     effectiveness of such termination, assignment or sublease (i) the Loan to
     Value Ratio (as defined in the Loan Agreement, and taking into
     consideration the value of all of the Projects, as defined in the Loan
     Agreement) is not greater than 55%, and (ii) the Debt Service Coverage
     Ratio (as defined in the Loan Agreement, and taking into consideration the
     loss of income resulting from such termination, assignment or sublease, as
     projected by the Mortgagee in its reasonable discretion) is not less than
     1.40:1.0. A material Change shall include but not be limited to any
     material Change in the amount or time of payment of the rent or additional
     rent, the length of term or square footage of the premises under any Space
     Lease or any other Change which would materially adversely affect the
     Mortgagor's rights under the Space Lease, or would affect the Mortgagee's
     rights under the Space Lease or the value of the Space Lease as collateral
     security for the indebtedness.

               (ii) The Mortgagor shall, at its sole cost and expense, enforce
          the Space Leases in accordance with their terms; and shall appear in
          and defend any action or proceeding arising to which it is 




                                       29

          a party under or in any manner connected with any of the Space Leases.

          (e) The Mortgagor shall deliver to the Mortgagee a copy of each notice
     of default sent or received by it relating in any way to any Space Lease
     promptly upon, but in any event within five (5) business days after, its
     sending or receipt thereof.

     4.3. The Mortgagor's Rights and Powers.

     4.3.1. The Mortgagor hereby irrevocably, in the name of the Mortgagor or
otherwise, authorizes and empowers the Mortgagee, and assigns and transfers unto
the Mortgagee, and constitutes and appoints the Mortgagee its true and lawful
attorney-in-fact, coupled with an interest and as its agent, irrevocably, with
full power or substitution for it and in its name, but solely for the following
purposes: (i) to exercise and enforce every right, power, remedy, authority,
option and privilege of the Mortgagor under the Space Leases, and as such
attorney-in-fact, the Mortgagee may subordinate, terminate, cancel or modify the
Space Leases, accept the surrender of the Space Leases, give any notice, take
any action resulting in such subordination, termination, cancellation,
modification or surrender, give any authorization, furnish any information, make
any demands, execute any instruments and take any and all other action on behalf
of and in the name of the Mortgagor which in the opinion of the Mortgagee may be
necessary or appropriate to be given, furnished, made, exercised or taken by the
Mortgagor under the Space Leases in order to comply therewith, to perform the
conditions thereof or to prevent or remedy any default by the Mortgagor
thereunder or to enforce any of the Mortgagor's rights and remedies there-under,
and (ii) to ask, require, demand, receive and collect and give acquittances for
the Income (as hereinafter defined), and on nonpayment thereof to sue for,
recover and receive the same, and on payment thereof to give sufficient
releases, receipts, discharges and acquittances thereof; to endorse any checks
or other instruments or orders in connection therewith and to file any claims or
take any action or institute any proceedings which the Mortgagee may deem to be
necessary or advisable; provided, however, that the power provided for in this
sentence may not be exercised by the Mortgagee unless an Event of Default shall
have occurred and be continuing. "Income" shall mean all deposits, rents,
issues, profits, revenues, royalties, and other revenue producing arrangements,
whether written or oral, and all monetary benefits of, and/or derived from,
and/or sums payable under and by virtue of the Space Leases and/or the Premises.

<PAGE>



     4.3.2. So long as there shall not have occurred and then be continuing any
Event of Default and until such right of the Mortgagor is terminated by the
Mortgagee as provided in SECTION 4.3.3, the Mortgagee will not exercise its
rights pursuant to SECTION 4.3.1, and, notwithstanding anything in SECTION 4.3.1
to the contrary, the Mortgagor shall have the right (but limited as hereinafter
provided) to exercise all of its rights under the Space Leases, including,
without limitation, to collect and receive all rents, income, receipts,
revenues, issues and profits arising therefrom, provided that the Mortgagor
shall at all times comply with, observe and perform, in the exercise of such
right, all of the provisions of this Mortgage and the other Security Documents
applicable to the Space Leases; provided, further, that no action shall be taken
or failed to be taken by the Mortgagor which would impair the Collateral or any
other collateral security for the Obligations provided for in the Security
Documents.

     4.3.3. The Mortgagee, upon the occurrence and during the continuance of an
Event of Default, at its option and upon written notice to the Mortgagor, shall
have the right to terminate the right of the Mortgagor to exercise its rights
under the Space Leases, and, thereupon, in addition, the Mortgagee, at any time
thereafter, at its option, shall have the complete right, power and authority
hereunder to exercise and enforce all rights, powers, remedies, authority,
options and privileges of the Mortgagor under the Space Leases in the name of
the Mortgagor or the Mortgagee, to enforce all obligations of the other parties
to the Space Leases and to exercise and enforce all of its rights and remedies
hereunder and under law not exercisable prior to an Event of Default.

     4.3.4. The Mortgagor does hereby direct each and all of the Space Tenants
under the Space Leases and all contractual obligors of the Mortgagor to pay any
Income to the Mortgagee upon written demand for payment thereof by the Mortgagee
without further inquiry. It is understood and agreed, however, that no such
demand shall be made unless an Event of Default shall have occurred and be
continuing. No such Space Tenant or obligor shall be obliged to account to the
Mortgagor for any amounts paid to the Mortgagee by reason of any payment made to
the Mortgagee pursuant to such demand and, upon any such payment to the
Mortgagee, shall be pro tanto released from their obligations to the Mortgagor
with respect to such payment. Each Space Tenant shall be permitted to rely on
any communication from the Mortgagee pursuant hereto, and under no circumstances
shall such Space Tenant be obligated to the Mortgagor for any payments made to
the Mortgagee hereunder. Until such demand is made, the Mortgagor is authorized
to collect or enforce or continue 




                                       31

collecting or enforcing such Income in accordance with the provisions of this
Mortgage.

     4.3.5. The Mortgagee shall not have any duty as to the collection or
protection of the Collateral or any income thereon or payments with respect
thereto, or as to the preservation of any rights pertaining thereto beyond the
safe custody of any thereof actually in its possession. In no instance shall the
Mortgagee be responsible to lessees for payment of interest upon, or return of,
any lease security deposits, except as provided by law or as provided in the
leases and then only if and to the extent that such deposits are received by the
Mortgagee. The Mortgagor hereby waives notice of acceptance hereof, and except
as otherwise specifically provided herein or required by provision of law which
may not be waived, hereby waives any and all notices or demands with respect to
any exercise by the Mortgagee of any rights or powers which it may have or to
which it may be entitled with respect to the Collateral.

     4.3.6. The Mortgagor hereby irrevocably constitutes and appoints the
Mortgagee as the true and lawful attorney-in-fact of the Mortgagor, which
appointment is coupled with an interest, with full power of substitution, to
proceed from time to time in the Mortgagor's name in any statutory or
non-statutory proceeding affecting the Mortgagor or any Collateral, and the
Mortgagee or its nominee may (i) execute and file proof of claim for the full
amount of any Collateral and vote such claims for the full amount thereof (A)
for or against any proposal or resolution, (B) for a trustee or trustees or for
a receiver or receivers or for a committee of creditors and/or (C) for the
acceptance or rejection of any proposed arrangement, plan of reorganization,
composition or extension, and the Mortgagee or its nominee may receive any
payment or distribution and give acquittance therefor and may exchange or
release Collateral; (ii) endorse any draft or other instrument for the payment
of money, execute releases and negotiate and enter into settlements; and (iii)
execute all such other documents or instruments as may be necessary or expedient
to be executed by the Mortgagor for any of the purposes of this Mortgage;
provided, however, that the power provided for in this sentence may be exercised
by the Mortgagee only while an Event of Default is continuing. The Mortgagee
shall have no duty to exercise any of the aforesaid rights, privileges or
options and shall not be responsible for any failure to do so or delay in so
doing.

     4.4. Remedies and Entry Upon Default.

     4.4.1. So long as no Event of Default shall have occurred and be
continuing, the Mortgagor shall have the right to collect (but not more than one
(1) month in advance) and retain all of the rents, gross receipts and other
payments, if any, from the Space Leases and from the Mortgaged Premises
generally, and the Mortgagee agrees that customary initial rent payments,
security deposits and reimbursements by a Space Tenant to the Mortgagor on
account of alterations made by the Mortgagor for the benefit of the Space Tenant
are permissible advance payments by the Space Tenant.

     4.4.2. Upon any Event of Default, the Mortgagee may, but shall not be
obligated to:

          (a) terminate the rights of the Mortgagor referred to in SECTION 4.3
     hereof and exercise all of the powers, rights and remedies provided for in
     SECTION 4.3 hereof, including those to be exercised only from and after an
     Event of Default;

          (b) at any time and from time to time, without notice to, or assent
     by, the Mortgagor or any other Person, but without affecting any of the
     Obligations, in the name of the Mortgagor or in the name of the Mortgagee,
     notify the account debtors and obligors on any or all of the Space Leases
     to make payment and performance directly to the Mortgagee, and demand,
     collect, receive, compound and give acquittance for the Space Leases or any
     part thereof; extend the time of payment and performance of, compromise or
     settle for cash, credit or otherwise, upon any terms and conditions, any of
     the Space Leases; endorse to the order of the Mortgagee checks, drafts or
     other orders or instruments for the payment of moneys payable to the
     Mortgagor which shall be issued in respect of any of the Space Leases; file
     any claims, commence, maintain or discontinue any actions, suits or other
     proceedings deemed by the Mortgagee necessary or advisable for the purpose
     of collecting upon or enforcing any of the Space Leases; and execute any
     instrument and do all other things deemed necessary and proper by the
     Mortgagee to protect and preserve and realize upon the Space Leases and/or
     the other rights contemplated hereby; the Mortgagor hereby irrevocably
     constitutes and appoints the Mortgagee as such the Mortgagor's lawful
     attorney-in-fact, coupled with an interest, and its agent for the foregoing
     purposes;

          (c) demand, collect, sue for, attach, levy, recover, receive,
     compromise and adjust, and make, execute and deliver receipts and releases
     for all Income that may then be or may thereafter become due, owing or
     payable with respect to the Premises or any part or parts thereof from any
     present or future lessees, tenants, subtenants or occupants thereof or from
     any present or future contract obligors; and/or

          (d) pay, in such order as the Mortgagee in its sole discretion shall
     determine, from and out of the Income collected in connection with the
     Premises and/or the Collateral or any part or parts thereof or from or out
     of any other funds (less the expense of collection, including reasonable
     attorneys' fees and disbursements), any taxes, assessments, water rates,
     sewer rates, or other government or other charges levied, assessed or
     imposed against the Premises or any part or part thereof, and also any and
     all other charges, costs and expenses which the Mortgagee deems necessary
     or advisable to pay in respect of the management or operation of the
     Premises, including, without limitation, the costs of insurance policies,
     repairs and alterations, commissions for renting the Premises or any part
     or parts thereof, legal expenses in enforcing claims, preparing papers or
     procuring any other services that may be required and any amounts payable
     under or pursuant to any Lease; all amounts so paid and expended shall be
     payable on demand, together with interest at the Involuntary Rate from the
     date incurred until paid, and be deemed to be included within the
     Obligations and secured by this Mortgage; the provisions of this ARTICLE
     and the rights given to the Mortgagee hereby shall inure to the benefit of
     the Mortgagee even though the Mortgagee does not enter and take possession
     of the Premises; any balance remaining after the indebtedness and the other
     obligations of the Mortgagor under the Loan and Security Documents shall
     have been paid in full shall be turned over to the Person lawfully entitled
     thereto. Neither the entry upon and taking possession of the Mortgaged
     Premises, nor the collection and application of the rents, gross receipts
     or other charges thereof, nor any other action taken by the Mortgagee in
     connection therewith, shall cure or waive any default hereunder or waive or
     modify any notice thereof or notice of acceleration of the Note theretofore
     given by the Mortgagee.

     4.4.3. If an Event of Default shall have occurred and be continuing, a
notice in writing by the Mortgagee to the Space Tenants under the Space Leases
advising them that the Mortgagor has defaulted hereunder and

requesting that all future payments of rent, additional rent or other charges
under the Space Leases be made to the Mortgagee (or its agent) shall be
construed as conclusive authority to such Space Tenants that such payments are
to be made to the Mortgagee (or its agent). Each Space Tenant shall be fully
protected in making such payments to the Mortgagee (or its agent) and be given
full credit against its obligations under the applicable Space Lease to the
extent of payments made to the Mortgagee (or its agent) pursuant to any such
notice; and the Mortgagor hereby irrevocably constitutes and appoints the
Mortgagee the attorney-in-fact and agent of the Mortgagor, coupled with an
interest, for the purpose of endorsing the consent of the Mortgagor on any such
notice.

     4.5. No Obligation of Mortgagee.

     4.5.1. The Mortgagee shall not be obligated to perform or discharge any
obligation of the Mortgagor as a result of the assignment hereby effected, and
the Mortgagor hereby agrees to indemnify and hold the Mortgagee harmless from
and against any and all liability, loss or damage which the Mortgagee may incur
by reason of any act of the Mortgagee under this Mortgage, other than as a
result of the Mortgagee's willful misconduct or gross negligence and other than
as a result of the Mortgagee's misconduct or negligence after the Mortgagee has
taken possession of the Premises. Should the Mortgagee (i) incur any such
liability, loss or damage by reason of this Mortgage and which is covered by the
foregoing indemnity, or in defense against any such claims or demands, or (ii)
perform any acts or covenants on the part of the Mortgagor to be performed under
the Space Leases, or (iii) pay for the account of the Mortgagor (other than from
Income or from funds delivered to the Mortgagee by the Mortgagor to be held in
trust for such purpose), any and all sums, costs and expenses for the discharge
of taxes, assessments, water rents or other liens against the Collateral or any
part thereof, or on account of insurance premiums or repairs, and also any
amounts and expenses necessary to perform any covenants and conditions to be
performed on the part of the Mortgagor under the Space Leases, the amount
thereof, including costs, expenses and reasonable attorneys' fees, together with
interest thereon at the Involuntary Rate from the date such expenses were paid
by the Mortgagee to the date of payment to the Mortgagee by the Mortgagor, shall
be included in the Obligations secured by this Mortgage, and the Mortgagor shall
reimburse the Mortgagee therefor upon demand.

     4.5.2. The acceptance by the Mortgagee of this Mortgage, with all the
rights, powers, privileges and

authority so created, shall not at any time or in any event obligate the
Mortgagee to appear in or defend any action or proceeding relating to the
Collateral, or to take any action hereunder or thereunder, or to expend any
money or incur any expenses or perform or discharge any obligation, duty or
liability under the Collateral.


                                   ARTICLE V.

                Security Agreement Under Uniform Commercial Code

     5.1. This Mortgage shall constitute a security agreement within the meaning
of the Uniform Commercial Code of the State (the "Code"), and the Mortgagee
shall be deemed to be the "secured party" (as that term is defined in the Code).
The Mortgagor hereby grants to the Mortgagee, as additional collateral for the
obligations under the Note and the other Obligations secured hereby, a security
interest in and to all of the Mortgaged Premises which are considered or as
shall be determined to be personal property or "fixtures" (as defined in the
Code), including, without limitation, the Building Service Equipment, the
Furnishings, the Payments and Intangibles, all books, records, licenses and
certificates of the Mortgagor relating to the Mortgaged Premises, together with
all replacements thereof, substitutions therefor or additions thereto (said
property being sometimes hereinafter referred to as the "Personal Property").
The Mortgagor agrees that a security interest shall attach to the Personal
Property for the benefit of the Mortgagee to secure the indebtedness evidenced
by the Note and the other Obligations secured by this Mortgage and all other
sums and charges which may become due hereunder, thereunder or under any of the
other Security Documents. The Mortgagor hereby authorizes the Mortgagee to file
financing and continuation statements with respect to the Personal Property
without the signature of the Mortgagor, if permitted by the Code. In any event
the Mortgagor covenants to execute such financing and continuation statements as
the Mortgagee may reasonably request. If an Event of Default shall occur and be
continuing, the Mortgagee, pursuant to the appropriate provisions of the Code,
shall have the option of proceeding as to both real and personal property in
accordance with its rights and remedies in respect of real property under this
Mortgage and the law of the State, in which event the default provisions of the
Code shall not apply. The Mortgagor agrees that, in the event the Mortgagee
shall elect to proceed with respect to the Personal Property separately from the
real property, unless a greater period shall then be mandated by the Code, five
(5) days notice of the sale of the Personal Property shall be reasonable notice.
The expenses of retaking, holding,

preparing for sale and selling incurred by the Mortgagee shall be assessed
against the Mortgagor and shall include, but not be limited to, the reasonable
legal expenses incurred by Mortgagee. The Mortgagor agrees that it will not
remove or permit to be removed from the Mortgaged Premises any of the Personal
Property without the prior written consent of the Mortgagee except as set forth
in SECTION 2.7.2. All replacements, renewals and additions to the Personal
Property shall be and become immediately subject to the security interest of
this Mortgage and the provisions of this ARTICLE V. The Mortgagor warrants and
represents that all Personal Property now is free and clear of all liens,
encumbrances or security interests other than the Permitted Encumbrances, and
that all replacements of the Personal Property, substitutions therefor or
additions thereto, unless the Mortgagee otherwise consents, will be, free and
clear of liens, encumbrances or security interests of others.


                                   ARTICLE VI.

                         Events of Default and Remedies


     6.1. Events of Default. The whole of the outstanding Principal Amount (as
defined in the Note) and accrued interest evidenced by the Note shall, at the
option of the Mortgagee, become due upon the happening of an Event of Default;
provided, however, that upon the occurrence of a default specified in SECTIONS
5.01(f) or 5.01(g) of the Loan Agreement, or upon the occurrence of any other
default specified in any Loan Document (as defined in the Loan Agreement) where
provision is made for acceleration to occur automatically as a consequence
thereof, all sums owing to the Mortgagee thereunder shall automatically become
immediately due and payable.

     6.2. Remedies.

     6.2.1. If an Event of Default shall occur and be continuing, the Mortgagee,
at its option, may:

          (1) by notice to the Mortgagor, declare the entire principal amount of
     the Note then outstanding and all accrued and unpaid interest thereon and
     all obligations of the Mortgagor to the Mortgagee to be immediately due and
     payable, and upon such declaration such principal and interest and all
     obligations of the Mortgagor to the Mortgagee shall become and be
     immediately due and payable, anything in the Note, the Loan Agreement or in
     this Mortgage or in 




                                       37

<PAGE>


     any of the other Security Documents to the contrary notwithstanding;

          (2) during the continuance of any such Event of Default, Mortgagee
     personally, or by its agents or attorneys, may enter into and upon all or
     any part of the Premises, and each and every part thereof, and is hereby
     given a right and license and appointed Mortgagor's attorney-in-fact and
     exclusive agent to do so, and may exclude Mortgagor, its agents and
     servants wholly therefrom; and having and holding the same, may use,
     operate, manage and control the Mortgaged Premises and conduct the business
     thereof, either personally or by its superintendents, managers, agents,
     servants, attorneys or receivers; and upon every such entry, Mortgagee, at
     the expense of the Mortgaged Premises, from time to time, either by
     purchase, repairs or construction, may maintain and restore the Mortgaged
     Premises whereof it shall become possessed as aforesaid, may complete the
     construction of the Improvements and in the course of such completion may
     make such changes in the contemplated Improvements as it may deem desirable
     and may insure the same; and likewise, from time to time, at the expense of
     the Mortgaged Premises, Mortgagee may make all necessary or proper repairs,
     renewals and replacements and such useful alterations, additions,
     betterments and improvements thereto and thereon as to it may seem
     advisable; and in every such case Mortgagee shall have the right to manage
     and operate the Mortgaged Premises and to carry on the business thereof and
     exercise all rights and powers of Mortgagor with respect thereto either in
     the name of Mortgagor or otherwise as it shall deem best; and Mortgagee
     shall be entitled to collect and receive the rents, income, issue and
     profits of the Mortgaged Premises, and every part thereof, all of which
     shall for all purposes constitute property of Mortgagor; and in furtherance
     of such right Mortgagee may collect the rents payable under all leases of
     the Mortgaged Premises directly from the lessees thereunder upon notice to
     each such lessee that an Event of Default exists hereunder accompanied by a
     demand on such lessee for the payment to Mortgagee of all rents due and to
     become due under its Space Lease, and Mortgagor FOR THE BENEFIT OF
     MORTGAGEE AND EACH SUCH SPACE TENANT hereby covenants and agrees that the
     Space Tenant shall be under no duty to question the accuracy of Mortgagee's
     statement of default and shall unequivocally be authorized to pay said
     rents to Mortgagee without regard to the truth of Mortgagee's statement of
     default and notwithstanding notices from Mortgagor disputing the existence
     of an Event of 




                                       38

<PAGE>


     Default such that the payment of rent by the Space Tenant to Mortgagee
     pursuant to such a demand shall constitute performance in full of the Space
     Tenant's obligation under the Space Lease for the payment of rents by the
     Space Tenant to Mortgagor; and after deducting the expenses of conducting
     the business thereof and of all maintenance, repairs, renewals,
     replacements, alterations, additions, betterments and improvements and
     amounts necessary to pay for taxes, assessments, insurance and prior or
     other proper charges upon the Mortgaged Premises or any part thereof, as
     well as just and reasonable compensation for the services of Mortgagee and
     for all attorneys, counsel, agents, clerks, servants and other employees by
     it engaged and employed, Mortgagee shall apply the moneys arising as
     aforesaid as provided below.

          (3) with or without entry, personally or by its agents or attorneys,
     insofar as applicable, may:

               a. sell the Mortgaged Premises to the extent permitted and
          pursuant to the procedures provided by law, and all estate, right,
          title and interest, claim and demand therein, and right of redemption
          thereof, at one or more sales as an entity or in parcels or parts, and
          at such time and place upon such terms and after such notice thereof
          as may be required or permitted by law; or

               b. institute proceedings for the complete or partial foreclosure
          of this Mortgage; or

               c. take such steps to protect and enforce its rights whether by
          action, suit or proceeding in equity or at law for the specific
          performance of any covenant, condition or agreement in the Note or in
          the Loan Agreement or in this Mortgage, or in aid of the execution of
          any power herein granted, or for any foreclosure hereunder, or for the
          enforcement of any other appropriate legal or equitable remedy or
          otherwise as Mortgagee shall elect.

          (4) exercise any and all remedies available to a secured party under
     the UCC in such order and in such manner as the Mortgagee in its sole
     discretion may determine; provided, however, that the expenses of retaking,
     holding, preparing for sale or the like, shall include reasonable
     attorneys' fees and 



                                       39

<PAGE>


     other expenses of the Mortgagee and be secured by this Mortgage;

          (5) exercise any or all of its other rights and remedies provided
     herein, in any of the Security Documents, or other document or agreement
     now or hereafter securing all or any portion of the Obligations secured
     hereby, or as provided by law, in such order of priority as the Mortgagee
     shall determine in its sole discretion.

     6.2.2. Mortgagee may adjourn from time to time any sale by it to be made
under or by virtue of this Mortgage by announcement at the time and place
appointed for such sale or for such adjourned sale or sales; and, except as
otherwise provided by any applicable provision of law, Mortgagee, without
further notice or publication, may make such sale at the time and place to which
the same shall be so adjourned.

     6.2.3. Upon the completion of any sale or sales made by Mortgagee under or
by virtue of this SECTION 6.2, Mortgagee, or an officer of any court empowered
to do so, shall execute and deliver to the accepted purchaser or purchasers a
good and sufficient instrument or instruments conveying, assigning and
transferring all estate, right, title and interest in and to the property and
rights sold. Mortgagee is hereby irrevocably appointed the true and lawful
attorney of Mortgagor, in its name and stead, to make all necessary conveyances,
assignments, transfers and deliveries of the Mortgaged Premises and rights so
sold and for that purpose Mortgagee may execute all necessary instruments of
conveyance, assignment and transfer, and may substitute one or more persons with
like power, Mortgagor hereby ratifying and confirming all that its said attorney
or such substitute or substitutes shall lawfully do by virtue hereof.
Nevertheless, Mortgagor, if requested by Mortgagee, shall ratify and confirm any
such sale or sales by executing and delivering to Mortgagee or to such purchaser
or purchasers all such instruments as may be advisable, in the judgment of
Mortgagee, for the purpose, and as may be designated in such request. Any such
sale or sales made under or by virtue of this SECTION 6.2 shall operate to
divest all the estate, right, title, interest, claim and demand whatsoever,
whether at law or in equity, of Mortgagor in and to the properties and rights so
sold, and shall be a perpetual bar both at law and in equity against Mortgagor
and against any and all persons claiming or who may claim the same, or any part
thereof from, through or under Mortgagor.

     6.2.4. In the event of any sale or sales made under or by virtue of this
SECTION 6.2 (whether made under the power of sale herein granted or under or by
virtue of judicial proceedings or of a judgment or decree of foreclosure and
sale), the entire principal of, and interest on, the Note, if not previously due
and payable, and all other sums required to be paid by Mortgagor pursuant to
this Mortgage, immediately thereupon shall, anything in the Note or in this
Mortgage to the contrary notwithstanding, become due and payable.

     6.2.5. The purchase money, proceeds or avails of any sale or sales made
under or by virtue of this SECTION 6.2, together with any other sums which then
may be held by Mortgagee under this Mortgage, whether under the provisions of
this SECTION 6.2, or otherwise, shall be applied as follows:

          First: To the payment of the costs and expenses of such sale,
     including reasonable compensation to Mortgagee, its agents and counsel, and
     of any judicial proceedings wherein the same may be made, and of all
     expenses, liabilities and advances made or incurred by Mortgagee under this
     Mortgage, together with interest at the Involuntary Rate on all advances
     made by Mortgagee, and of all taxes, assessments or other charges, except
     any taxes, assessments or other charges subject to which the Mortgaged
     Premises shall have been sold.

          Second: To the payment of the whole amount then due, owing or unpaid
     upon the Note for principal and interest, with interest on the unpaid
     principal at the Involuntary Rate from and after the happening of any Event
     of Default from the due date of any such payment of principal until the
     same is paid.

          Third: To the payment of any other sums required to be paid by
     Mortgagor pursuant to any provision of this Mortgage or of the Note.

          Fourth: To the payment of the surplus, if any, to whomsoever may be
     lawfully entitled to receive the same.

     6.2.6. Upon any sale or sales made under or by virtue of this SECTION 6.2,
Mortgagee may bid for and acquire the Mortgaged Premises or any part thereof and
in lieu of paying cash therefor may make settlement for the purchase price by
crediting upon the indebtedness secured by this Mortgage the net sales price
after deducting therefrom

the expenses of the sale and the costs of the action and any other sums which
Mortgagee is authorized to deduct under this Mortgage.

     6.2.7. In case an Event of Default shall have happened and be continuing,
then, upon written demand of Mortgagee, Mortgagor will pay to Mortgagee the
whole amount which then shall have become due and payable on the Note, for
principal or interest or both, as the case may be, and after the happening of
said Event of Default will also pay to Mortgagee interest at the Involuntary
Rate on the then unpaid principal of the Note, and the sums required to be paid
by Mortgagor pursuant to any provision of this Mortgage or the Note, and in
addition thereto such further amount as shall be sufficient to cover the costs
and expenses of collection, including reasonable compensation to Mortgagee, its
agents and counsel and any expenses incurred by Mortgagee hereunder. In the
event Mortgagor shall fail forthwith to pay such amounts upon such demand,
Mortgagee shall be entitled and empowered to institute such action or
proceedings at law or in equity as may be advised by its counsel for the
collection of the sums so due and unpaid, and may prosecute any such action or
proceedings to judgment or final decree, and may enforce any such judgment or
final decree against Mortgagor and collect, out of the property of Mortgagor
wherever situated, as well as out of the Mortgaged Premises, in any manner
provided by law, moneys adjudged or decreed to be payable.

     6.2.8. Mortgagee shall be entitled to recover judgment as aforesaid either
before, after or during the pendency of any proceedings for the enforcement of
the provisions of this Mortgage; and the right of Mortgagee to recover such
judgment shall not be affected by any entry or sale hereunder, or by the
exercise of any other right, power or remedy for the enforcement of the
provisions of this Mortgage, or the foreclosure of the lien hereof; and in the
event of a sale of the Mortgaged Premises and of the application of the proceeds
of sale, as in this Mortgage provided, to the payment of the debt hereby
secured, Mortgagee shall be entitled to enforce payment of, and to receive all
amounts then remaining due and unpaid upon, the Note, and to enforce payment of
all other charges, payments and costs due under this Mortgage, and shall be
entitled to recover judgment for any portion of the debt remaining unpaid, with
interest at the Involuntary Rate. In case of proceedings against Mortgagor in
insolvency or bankruptcy or any proceedings for its reorganization or involving
the liquidation of its assets, then Mortgagee shall be entitled to prove the
whole amount of principal and interest due upon the Note to the full amount
thereof, and all other payments, charges and costs due under this Mortgage and
the Note, 



                                       42

without deducting therefrom any proceeds obtained from the sale of the whole or
any part of the Mortgaged Premises, provided, however, that in no case shall
Mortgagee receive a greater amount than such principal and interest and such
other payments, charges and costs from the aggregate amount of the proceeds of
the sale of the Mortgaged Premises and the distribution from the estate of
Mortgagor.

     6.2.9. No recovery of any judgment by Mortgagee and no levy of an execution
under any judgment upon the Mortgaged Premises or upon any other property of
Mortgagor shall affect in any manner or to any extent, the lien of this Mortgage
upon the Mortgaged Premises or any part thereof, or any liens, rights, powers or
remedies of Mortgagee hereunder, but such liens, rights, powers and remedies of
Mortgagee shall continue unimpaired as before.

     6.2.10. Any moneys thus collected by Mortgagee under this SECTION 6.2 shall
be applied by Mortgagee in accordance with the provisions of SECTION 6.2.5
hereof.

     6.2.11. After the happening of any Event of Default and immediately upon
the commencement of any action, suit or other legal proceedings by Mortgagee to
obtain judgment for the principal of, or interest on, the Note and other sums
required to be paid by Mortgagor pursuant to any provision of this Mortgage or
the Note, or of any other nature in aid of the enforcement of the Note or of
this Mortgage, Mortgagor will (a) waive the issuance and service of process and
enter its voluntary appearance in such action, suit or proceeding and (b) if
required by Mortgagee, consent to the appointment of a receiver or receivers of
all or part of the Mortgaged Premises and of any or all of the rents, issues and
profits of the Mortgaged Premises in respect thereof. After the happening of any
Event of Default and during its continuance, or upon the commencement of any
proceedings to foreclose this Mortgage or to enforce the specific performance
hereof or in aid thereof or upon the commencement of any other judicial
proceeding to enforce any right of Mortgagee, Mortgagee shall be entitled, as a
matter of right, if it shall so elect, without the giving of notice to any other
party and without regard to the adequacy or inadequacy of any security for the
indebtedness secured hereby, forthwith either before or after declaring the
unpaid principal of the Note to be due and payable, to the appointment of such a
receiver or receivers.

     6.2.12. Notwithstanding the appointment of any receiver, liquidator or
trustee of Mortgagor, or of any of its property, or of the Mortgaged Premises,
or any part 


                                       43

thereof, Mortgagee shall be entitled to retain possession and control of all
property now or hereafter held under this Mortgage.

     6.2.13. Mortgagor will not at any time insist upon, or plead, or in any
manner whatever claim or take any benefit or advantage of any stay or extension
or moratorium law, any exemption from execution or sale of the Mortgaged
Premises or any part thereof, wherever enacted, now or at any time hereafter in
force, which may affect the covenants and terms of performance of this Mortgage,
nor claim, take or insist upon any benefit or advantage of any law now or
hereafter in force providing for the valuation or appraisal of the Mortgaged
Premises, or any part thereof, prior to any sale or sales thereof which may be
made pursuant to any provision herein, or pursuant to the decree, judgment or
order of any court of competent jurisdiction; nor, after any such sale or sales,
claim or exercise any right under any statute heretofore or hereafter enacted to
redeem the property so sold or any part thereof and Mortgagor hereby expressly
waives all benefit or advantage of any such law or laws, and covenants not to
hinder, delay or impede the execution of any power herein granted or delegated
to Mortgagee, but to suffer and permit the execution of every power as though no
such law or laws had been made or enacted.

     6.2.14. During the continuance of any Event of Default and pending the
exercise by Mortgagee of its right to exclude Mortgagor from all or any part of
the Premises, Mortgagor agrees to pay the fair and reasonable rental value for
the use and occupancy of the Premises or any portion thereof which are in its
possession for such period and, upon default of any such payment, will vacate
and surrender possession of the Premises to Mortgagee or to a receiver, if any,
and in default thereof may be evicted by any summary action or proceeding for
the recovery of possession of premises for non-payment of rent, however
designated.

     6.3. Sale; No Marshalling of Assets.

     6.3.1. In case of a foreclosure sale, all of the Mortgaged Premises may be
sold in one parcel even though the proceeds of such sale exceed or may exceed
the indebtedness secured hereby. The Mortgagee shall not be required to exercise
any rights under this Mortgage before proceeding against any other security,
shall not be required to proceed against other security before proceeding under
this Mortgage, and shall not be precluded from proceeding against any or all of
any security held by the Mortgagee 



                                       44

for any or all of the indebtedness secured hereby in any order or at the same
time.

     6.3.2. The Mortgagor agrees, to the full extent that it may lawfully do so,
that in any foreclosure or other action brought by the Mortgagee to enforce this
Mortgage, it will not at any time insist upon or plead or in any way take
advantage of any appraisement, valuation, stay, marshalling of assets,
extension, redemption or moratorium law now or hereafter in force and effect so
as to prevent, hinder, delay or otherwise affect the enforcement of the
provisions of this Mortgage or any rights or remedies the Mortgagee may have
hereunder or by law.

     6.3.3. If the Mortgagee shall elect to accelerate the indebtedness by
following the occurrence of an Event of Default, the Mortgagor, within five (5)
days after demand, will pay to the Mortgagee, or any receiver appointed in
connection with the foreclosure of this Mortgage, any and all amounts then held
as security deposits under all Space Leases; and the Mortgagee or such receiver
shall be deemed to indemnify the Mortgagor against all claims of tenants in
respect of the security deposits so paid following such demand.

     6.4. Legal Expenses of the Mortgagee.

     6.4.1. The Mortgagor will pay to the Mortgagee, on demand, all costs,
charges and expenses (including, without limitation, reasonable attorneys' fees
and disbursements) incurred or paid at any time by the Mortgagee (i) in
connection with any action or proceeding to foreclose this Mortgage or to
recover or collect all, or any portion of the indebtedness; and (ii) in
connection with any modification or amendment or assignment of this Mortgage or
the other Security Documents, together with interest on each such payment made
by the Mortgagee at the Involuntary Rate from the date of the Mortgagee's demand
for such payment to the date of reimbursement by the Mortgagor.

     6.4.2. If any action or proceeding be commenced in which the Mortgagee is
made a party, or in which it becomes necessary to defend or uphold the lien of
this Mortgage, all reasonable sums paid by the Mortgagee for the expense of any
litigation to prosecute or defend the title, rights and lien created by this
Mortgage (including, without limitation, reasonable attorneys' fees) shall be
paid by the Mortgagor, together with interest thereon at the Involuntary Rate
from the date of the Mortgagee's demand for such payment to the date of
reimbursement by the Mortgagor.

     6.5. Remedies Cumulative; No Waiver; Etc.

     6.5.1. No remedy in this Mortgage conferred upon or reserved to the
Mortgagee is intended to be exclusive of any other remedy or remedies, and each
and every such remedy shall be cumulative, and shall be in addition to every
other remedy given hereunder or now or hereafter existing at law or in equity.
No delay or omission by the Mortgagee in exercising any right or power arising
upon any Event of Default shall impair any such right or power, or shall be
construed to be a waiver of or acquiescence in any such Event of Default; and
every power and remedy given by this Mortgage to the Mortgagee may be exercised
from time to time as often as the Mortgagee may determine it is appropriate to
do so.

     6.5.2. A waiver in one or more instances of compliance with any of the
terms, covenants, conditions or provisions of the Note, the Loan Agreement or of
the Security Documents shall apply to the particular instance or instances and
at the particular time or times only, and no such waiver shall be deemed a
continuing waiver. In any event, no waiver shall be effective, or be asserted by
the Mortgagor as having been made, unless set forth in a writing signed by the
Mortgagee.

     6.5.3. The Mortgagor waives and renounces all homestead and similar
exemption rights with respect to the Mortgaged Premises provided for by the
Constitution and laws of the United States and of the State as against the
collection of the Security Documents, or any part thereof.

     6.6. No Merger. It is the intention of the parties to this Mortgage that if
the Mortgagee shall at any time hereafter acquire title to all or any portion of
the Mortgaged Premises, then, and until the indebtedness secured hereby has been
paid in full, the interest of the Mortgagee hereunder and the lien of this
Mortgage shall not merge or become merged in or with the estate and interest of
the Mortgagee, as the holder and owner of title to all or any portion of the
Mortgaged Premises and that, until such payment, the estate of the Mortgagee in
the Mortgaged Premises and the lien of this Mortgage and the interest of the
Mortgagee hereunder shall continue in full force and effect to the same extent
as if the Mortgagee had not acquired title to all or any portion of the
Mortgaged Premises.

the Mortgagee (or any receiver of the Mortgaged Premises) shall have the right,
but not the obligation, to make any such payment, or to perform any other act or
take any appropriate action, including, without limitation, entry on the
Mortgaged Premises and performance of work thereat, as it, in its sole
discretion, may deem necessary to cause such other term, covenant, condition or
obligation to be promptly performed or observed on behalf of the Mortgagor or to
protect the security of this Mortgage. All amounts advanced by, or on behalf of,
the Mortgagee in exercising its rights under this SECTION 7.3 (including, but

therewith), together with interest thereon at the Involuntary Rate from the date
of the Mortgagee's demand upon the Mortgagor for reimbursement of such sums
until reimbursement by the Mortgagor, shall be payable by the Mortgagor to the

in the Note or such other Security Documents, be added to and deemed part of the
indebtedness secured by the lien of this Mortgage whether or not the provision
which obligates the Mortgagor to make any such payment to the Mortgagee
specifically so states.

     7.5. Captions. The captions used in this Mortgage are inserted only as a
matter of convenience and for reference, and in no way define, limit, enlarge or
describe the scope or intent of this Mortgage or in any other way affect this
Mortgage or the construction of any provision hereof.

     7.6. Successors and Assigns. The covenants and agreements contained in this
Mortgage shall run with the land and bind the Mortgagor, the successors and
assigns of the Mortgagor and all subsequent owners, encumbrances and Space
Tenants of the Mortgaged Premises, or any part thereof; and shall inure to the
benefit of the Mortgagee, its successors and assigns and all subsequent
beneficial owners of this Mortgage.

     7.7. Gender and Number. Wherever the context of this Mortgage so requires,
the neuter gender includes the masculine and/or feminine gender and the singular
number includes the plural.

     7.8. Severability. If any one or more of the provisions contained in this

in any respect, such invalidity, illegality or unenforceability shall not affect
any other provisions of this Mortgage; and this Mortgage shall, in such event,
be construed as if such invalid, illegal or unenforceable provision had never
been included.

     7.9. Usury. Anything in the Note, the Loan Agreement, this Mortgage or the
other Security Documents to the contrary notwithstanding, the Mortgagee shall
never be entitled to receive, collect or apply as interest on the principal
amount of the Note or any other of the obligations secured hereby any amount in
excess of the maximum rate of interest permitted to be charged by applicable
law. In the event the Mortgagee ever receives, collects or applies as interest
any such excess, the amount which would be excessive interest shall be applied
to the reduction of the principal amount of said obligations; and if said
principal

entitled thereto. In determining whether or not the interest paid or payable in
any specific instance shall exceed the highest lawful rate, the Mortgagor and
the Mortgagee shall to the maximum extent permitted by applicable law (i)
characterize any non-principal payment as an expense, fee or premium rather than
as interest, (ii) exclude voluntary prepayments and the effects thereof and
(iii) "spread" the total amount of interest throughout the entire contemplated
terms of the obligations so that the interest rate is uniform throughout the
entire said term.

     7.10. Controlling Law. This Mortgage shall be governed by, and construed
and enforced in accordance with, the laws of the State of New York applicable to
contracts made and to be wholly performed within such state.

Agreement and the other Security Documents, embodies the entire agreement and
understanding between the parties relating to the subject matter hereof.

of which shall be in such principal amounts as the Mortgagee and the Mortgagor
may agree and each of which shall secure a portion of the then unpaid principal
of the Note; provided, however, that the aggregate principal amount of all such
portions shall not exceed the then unpaid principal balance secured hereby. If
the Mortgagee and the Mortgagor agree to sever the lien of this Mortgage as
provided above, the then unpaid principal balance of the Note shall be severed
into portions and principal amounts corresponding to the portions and principal
amounts agreed upon by the Mortgagee and the Mortgagor, and two or more
substitute mortgages shall be issued, each of which shall secure a portion of
the severed indebtedness. The substitute mortgages are intended to secure the
same indebtedness secured by this Mortgage and are not intended to secure any
new or additional debt or obligation. Upon the recordation of the substitute
mortgages, the lien of this Mortgage shall be deemed transferred to the
substitute mortgages with the same effect as if the substitute mortgages were
originally recorded in lieu of this Mortgage and this Mortgage shall thereafter
be deemed superseded and replaced by the substitute mortgages.

     8.7.3. Nothing herein express or implied, shall be construed as or shall
constitute the consent of the Mortgagee to any such spreading or severance or
shall require the Mortgagee to consent thereto, and the Mortgagee may give or
withhold such consent in its sole discretion.

     8.8. Recording Statement. The real property is not principally improved by
a one or two family dwelling.

     2.3. To Maintain Priority of Lien.

     2.3.1. This Mortgage is and will be maintained as a valid first mortgage on
the Mortgaged Premises, and the Mortgagor will not, directly or indirectly,
create or suffer or permit to be created, or to stand against the Mortgaged
Premises or any portion thereof, or against the rents, issues and profits
therefrom, and will promptly discharge, any lien or charge prior to or upon a
parity with or junior to this Mortgage other than the Permitted Encumbrances;
provided, however, that the Mortgagor shall not be required to pay any
Imposition prior to the time it shall become due and payable subject to the
provisions of SECTION 2.4.1 hereof, and nothing herein contained shall prevent
the Mortgagor from contesting the validity of any such Imposition in accordance
with the provisions of SECTION 2.4.4. The Mortgagor will keep and maintain the
Mortgaged Premises, and every part thereof, free from all liens or lien notices,
of Persons supplying labor and/or materials in connection with any construction,
alteration, repair, improvement or replacement of the Improvements or of the
Building Service Equipment and Furnishings. If any such lien shall be filed
against the Mortgaged Premises, or any part thereof, the Mortgagor promptly
shall discharge the lien of record, by bonding or otherwise. The Mortgagor shall
exhibit to the Mortgagee, upon request, appropriate receipts or other
satisfactory evidence of the payment of the Impositions or any other item which
may, if not paid, give rise to a lien against the Mortgaged Premises.

     2.4. To Pay Impositions.

     2.4.1. The Mortgagor will pay or cause to be paid, as and when due and
payable, all Impositions levied upon the Mortgaged Premises or any part thereof,
together with all filing, registration or recording fees and all expenses
incident to the execution and acknowledgement of this Mortgage, any mortgage
supplemental hereto, and will pay all federal, state, county and municipal stamp
taxes and other taxes, duties, imposts, assessments and charges arising out of
or in connection with the execution and delivery of the Note, this Mortgage, any
mortgage supplemental hereto, or any instrument of further assurance, except
Oklahoma mortgage taxes which shall be paid by the Mortgagee. However, if by
law, any Imposition may at the option of the taxpayer be paid in installments
(whether or not interest shall accrue on the unpaid balance thereof), the
Mortgagor shall have the right to exercise such option and to pay such
Imposition, or cause it to be paid (together

                                      - 9 -

with any accrued interest on the unpaid balance) in installments as they fall
due and before any fine, penalty, further interest or cost may be added thereto.

     2.4.2. If an Event of Default shall occur and be continuing, then upon
demand of the Mortgagee, the Mortgagor shall deposit with the Mortgagee a sum
which bears the same relation to the annual insurance premiums for all insurance
required by the terms hereof and real estate taxes and assessments assessed
against the Mortgaged Premises for the insurance period or tax year then in
effect, as the case may be, as the number of months elapsed as of the date of
such demand since the last preceding installment of said premiums or taxes or
assessments shall have become due and payable bears to twelve (12). For the
purpose of this computation, the month in which such last preceding installment
of premiums or real estate taxes or assessments became due and payable and the
month in which such demand is given shall be included and deemed to have
elapsed. On the first day of the month next succeeding the month in which such
demand is given, and thereafter on the first day of each and every month during
the term of this Mortgage, the Mortgagor shall deposit with the Mortgagee a sum
equal to one-twelfth of such insurance premiums and such taxes and assessments
for the then-current insurance period and tax year, so that as each installment
of such premiums and taxes and assessments shall become due and payable, the
Mortgagor shall have deposited with the Mortgagee a sum sufficient to pay the
same. All such deposits shall be received and held as part of such deposit by
the Mortgagee (all such deposits to be held in an account without interest
thereon) and shall be applied to the payment of each installment of such
premiums and taxes and assessments as they shall become due and payable. The
Mortgagee shall, upon demand, furnish evidence to the Mortgagor of the making of
each such payment. If the amount of such premiums and taxes and assessments has
not been definitely ascertained at the time when any such monthly deposits are
required to be made, the Mortgagor shall make such deposits based upon the
amount of such premiums and taxes and assessments for the preceding year,
subject to adjustment as and when the amount of such premiums and taxes and
assessments are ascertained. If at any time when any installment of such
premiums and such taxes and assessments becomes due and payable the Mortgagor
shall not have deposited a sum sufficient to pay the same, the Mortgagor shall,
within five (5) days after demand, deposit any deficiency with the Mortgagee.
Upon payment in full of the indebtedness secured by this Mortgage, any remaining
amount on deposit with the Mortgagee shall be repaid to the Person lawfully
entitled thereto. If an Event

of Default shall occur and be continuing, the Mortgagee may, at its option,
apply all or any portion of the amounts then on deposit with the Mortgagee
pursuant to this SECTION 2.4.2 first to the payment of any premiums, taxes or
assessments then due, and any remaining amounts may be applied to the payment of
the indebtedness. The Mortgagor shall deliver to the Mortgagee all insurance and
tax bills promptly following receipt during any period when such monthly
deposits are to be made with the Mortgagee.

     2.4.3. The Mortgagor will pay all taxes and other governmental charges
(including, without limitation, stamp taxes), except income or franchise taxes
or similar taxes (other than Oklahoma mortgage tax), based upon or measured by
income, assessed by the United States government or any state or local
governmental authority and imposed on the Mortgagee, its successors by reason of
the ownership of this Mortgage or the Note or the receipt of the interest or
other sums payable thereunder or payable by either the Mortgagor or the
Mortgagee upon any increase in the indebtedness secured hereby, or any
modification, amendment, extension or consolidation of this Mortgage. Without
limiting the foregoing and subject to the limitations set forth above, the
Mortgagor will also pay the whole of any tax imposed, directly or indirectly, on
this Mortgage or the Note or the receipt of any portion of the Indebtedness in
lieu of a tax on the Mortgaged Premises or the Improvements and Building Service
Equipment, whether by reason of (a) the passage after the date of this Mortgage
of any law of the State deducting from the value of real property for the
purposes of taxation any lien thereon; (b) any change in the laws for the
taxation of Mortgages or debts secured by Mortgages for state or local purposes;
(c) a change in the means of collection of any such tax or otherwise; or (d) any
tax, whether or not now existing, assessed against, or withheld from, interest
or other payments made by the Mortgagor or assessed against this Mortgage and
which are assessed or levied by the government of any foreign nation or
political subdivision thereof, provided such tax liability shall not result from
the ownership of this Mortgage by a Person not a citizen of, or an entity not
formed under the laws of, the United States or any state. Within a reasonable
time after payment of any such tax or governmental charge, the the Mortgagor
will deliver to the Mortgagee satisfactory proof of payment thereof, subject,
however, to the right of the Mortgagor to contest Impositions as hereinafter set
forth. If the Mortgagor shall fail to pay such tax or charge within fifteen (15)
days after written notice, or if under applicable law the Mortgagor's payment or
agreement to pay

the same shall be unenforceable, the Mortgagee shall have the right to declare
the entire unpaid indebtedness and all accrued and unpaid interest thereon due
and payable on a date specified by the Mortgagee, but, in any event, not less
than thirty (30) days after written notice to the Mortgagor.

     2.4.4. The Mortgagor shall have the right to contest the amount or
validity, in whole or in part, of any Imposition, or to seek a reduction in the
valuation of the Mortgaged Premises, or any part thereof, as assessed for real
estate or personal property tax purposes by appropriate proceedings diligently
conducted in good faith, but only after payment of such Imposition, unless such
payment would operate as a bar to such contest or materially adversely interfere
with the prosecution thereof, in which event the Mortgagor may postpone or defer
payment of such Imposition (but not the payment of any monthly deposits pursuant
to SECTION 2.4.2 hereof); and upon request by the Mortgagor, the Mortgagee shall
postpone or defer payment of such Imposition; provided, however, that if at any
time the Mortgaged Premises, the Building Service Equipment, the Furnishings, or
any part thereof would, in the Mortgagee's reasonable judgment, by reason of
such postponement or deferment be in imminent danger of being forfeited or lost,
or if the Mortgagee might be subjected to any civil or criminal liability or
other sanction, then the Mortgagor, on demand, shall immediately pay or cause to
be paid the amount so contested and unpaid, together with all interest and
penalties in connection therewith.

     2.4.5. The certificate, advice or bill of the appropriate official
designated by law to make or issue the same or to receive payment of any
Imposition indicating the nonpayment of such Imposition shall be prima facie
evidence that such Imposition is due and payable but unpaid at the time of the
making or issuance thereof.

     2.5. Insurance; Restoration Following Casualty.

     2.5.1. Until the indebtedness secured hereby is paid in full, the Mortgagor
shall at its own expense at all times maintain or cause to be maintained on all
of the Mortgaged Premises (a) comprehensive general liability insurance,
including umbrella liability insurance, covering all claims for bodily injury,
including death, and property damage occurring on, in or about the Mortgaged
Premises in an aggregate amount of not less than Five Million Dollars
($5,000,000) per occurrence, and a single limit of not less than Two Million
Dollars ($2,000,000) per person and per occurrence for personal injury, bodily
injury

and property damage; the policy shall have no deductible or self insured
retention requirements; the policy limits of such insurance, if requested by the
Mortgagee, shall be increased from time to time to reflect what a reasonably
prudent owner or lessee of buildings or improvements similar in type and
locality to the Mortgaged Premises would carry; during any period of substantial
alterations or improvements in, on or to the Mortgaged Premises, the Mortgagor
will cause the comprehensive general liability insurance, including umbrella
liability insurance, endorsed to provide owners' and contractors' protective
liability coverage, including completed operations liability coverage; (b)
physical damage insurance (all risk non-reporting property insurance, including
earthquake insurance, with the Mortgagee named as loss payee), covering the
Mortgaged Premises for loss or damages resulting from the perils of fire,
lightning, earthquake, and such other risks and hazards as are provided under
the current standard "Extended Coverage Endorsement" and vandalism and malicious
mischief coverage, for the full replacement value of the Mortgaged Premises on a
stipulated and agreed-amount basis; (c) if the Mortgaged Premises is in an area
identified as a flood hazard area by the Secretary of Housing and Urban
Development, flood insurance, to the extent obtainable, in an amount equal to
the lesser of the full replacement value of the Mortgaged Premises or the
maximum amount available under the Federal flood insurance program; (d) boiler
and machinery insurance covering all boilers, machinery, air conditioning,
pressure vessels, and similar type equipment commonly covered under a broad-form
boiler and machinery policy, in an amount satisfactory to the Mortgagee; (e)
insurance against such other risks of damage, hazards, casualties and
contingencies in such amounts as the Mortgagee shall from time to time
reasonably require, provided that insurance against such other risks, hazards,
casualties or contingencies shall then be commonly carried by prudent owners or
lessees of building or improvements in the locality similar in character,
construction, use and occupancy to the Improvements, Building Service Equipment
and Furnishings on, or constituting a part of, the Mortgaged Premises; and (f)
loss of rents/business interruption coverage in an amount sufficient to pay all
Impositions, insurance premiums, interest and principal installments and all
other amounts due under the Note and the Loan Agreement and the normal operating
expenses of the Mortgaged Premises, all for a period of one (1) year.
Furthermore, the Mortgagee reserves the right to require additional insurance
and/or higher policy limits than heretofore specified if such additional
insurance and/or higher policy limits are commercially reasonable for similar
properties, which right

may be exercised by written notice to the Mortgagor, and, as soon thereafter as
practicable, but in any event within thirty (30) days of the receipt thereof,
the Mortgagor agrees to obtain insurance coverage complying with such notice.
The proceeds of all such insurance (except the insurance specified in SECTION
2.5.1(a)) shall be paid solely to the Mortgagee and be held, applied or
disbursed by the Mortgagee as provided in SECTIONS 2.5.7 and 2.5.8.

     2.5.2. All insurance required in SECTION 2.5.1 shall be evidenced by valid
and enforceable policies, in form and substance as shall be required by the
Mortgagee from time to time, and issued by and distributed among insurers of
recognized responsibility having an A.M. Best's Guide of A:XII or better, a
financial size category of Class XI or above, and the total limit of liability
shall not exceed ten percent (10%) of the total policyholders' surplus. Such
insurers shall be authorized to do business in the State and in all other
respects shall be reasonably satisfactory to the Mortgagee. The originals of all
such policies, or duplicate copies or certificates thereof, shall be delivered
to the Mortgagee concurrently with the execution and delivery of this Mortgage.
Thereafter, all renewal or replacement policies, or duplicate copies or
certificates thereof, shall be delivered to the Mortgagee not less than thirty
(30) days prior to the expiration date of the policy or policies to be renewed
or replaced, in each case accompanied by evidence reasonably satisfactory to the
Mortgagee that all premiums currently payable with respect to such policies have
been paid in full by or at the direction of the Mortgagor.

     2.5.3. All such insurance policies shall (a) except for any liability
policy required hereunder, contain a standard noncontributory form of mortgagee
clause (in favor of and entitling the Mortgagee to collect any and all proceeds
payable under such insurance), as well as a standard waiver of subrogation
endorsement, all to be in form and substance reasonably satisfactory to the
Mortgagee; (b) provide that such policies may not be cancelled or amended
without at least thirty (30) days prior written notice to the Mortgagee; and (c)
provide that no act, omission or negligence of the Mortgagor, or its agents,
servants or employees, or of any Space Tenant under any Space Lease, which might
otherwise result in a forfeiture of such insurance or any part thereof, shall in
any way affect the validity or enforceability of such insurance insofar as the
Mortgagee is concerned. The Mortgagor shall not carry separate insurance,
concurrent in kind or form or contributing in the event of loss with any
insurance

required under this SECTION 2.5. All losses under such insurance policies shall
be adjusted by the Mortgagor in the case of any single instance of such damage
or destruction not exceeding $200,000, by the Mortgagor and the Mortgagee in the
case of any such single instance of damage or destruction exceeding such amount,
provided that in no event shall the Mortgagor approve or consent to any final
adjustment in any amount exceeding the amount specified above in this sentence
without obtaining the Mortgagee's prior approval (which approval shall not be
unreasonably withheld) of the amount of such adjustment, and solely by the
Mortgagee in the case when an Event of Default exists and is continuing.

     2.5.4. The Mortgagor, at its expense, will furnish to the Mortgagee, within
ninety (90) days after written demand, but in no event, except for reasonable
cause, more frequently than annually, proof of the then full replacement value
of each of the Improvements and the Building Service Equipment and Furnishings
therein, such proof to be by appraisals reasonably satisfactory in form and
substance to the Mortgagee and prepared by an appraiser (who may be an appraiser
for the insurance company insuring such property) designated and paid for by the
Mortgagor and approved by the Mortgagee, which approval shall not be
unreasonably withheld or delayed.

     2.5.5. If the Mortgagee shall, by any means, acquire the title or estate of
the Mortgagor in or to any portion of the Mortgaged Premises, it shall thereupon
become the sole and absolute owner of all insurance policies affecting such
portion of the Mortgaged Premises held by, or required hereunder to be delivered
to, the Mortgagee, with the sole right to collect and retain all unearned
premiums thereon; and the Mortgagor shall be entitled only to a credit in
reduction of the then outstanding indebtedness secured hereby in the amount of
the short rate cancellation refund, when and if received by Mortgagee. The
Mortgagor agrees, immediately upon demand, to execute and deliver such
assignments or other authorizations or instruments as may, in the reasonable
opinion of the Mortgagee, be reasonably necessary or desirable to effectuate any
of the provisions of this SECTION 2.5.5.

     2.5.6. If any of the Improvements, Building Service Equipment or
Furnishings shall be damaged or destroyed, in whole or in part, by fire or other
casualty, the Mortgagor shall give prompt notice thereof to the Mortgagee, and,
without regard to the availability or adequacy of insurance proceeds, shall
promptly following

receipt of any insurance proceeds or the date when any such proceeds are made
available to the Mortgagor in accordance with the terms hereof, commence to
restore, replace, rebuild or alter the same as nearly as possible to the
condition, character and value thereof existing immediately prior to such damage
or destruction. Any insurance proceeds in respect of such damage or destruction,
or any Award (as defined in SECTION 3.2) for a partial taking which is not a
substantial or total taking, as such terms are referred to in ARTICLE III
hereof, at the option of the Mortgagee, may either (i) be applied as a
prepayment of the unpaid balance of the principal of the Note and of accrued and
unpaid interest thereon and as a payment of any other sums due and owing under
the Note, the Loan Agreement and the Security Documents, or (ii) be made
available to pay or reimburse costs incurred for restoration, replacement or
rebuilding necessitated as a result of such damage or destruction, or as a
result of such taking, as the case may be, or (iii) be used for any other
purpose or object deemed appropriate by the Mortgagee in connection with the
Mortgaged Premises, provided, however, that the Mortgagee may not elect either
option (i) or (iii) above if, and for so long as all of the following conditions
(collectively, the "Insurance or Award Conditions" have been and remain
satisfied: (a) no Event of Default has occurred and is continuing or would occur
as a result of such casualty or taking and no event has occurred that with the
passage of time or the giving of notice, or both, would constitute an Event of
Default; (b) the balance of the insurance proceeds or such Award either
initially paid to the Mortgagee or deposited with the Depository (as hereinafter
defined) or remaining from time to time, shall be sufficient, in the Mortgagee's
reasonable judgment, to complete the restoration, replacement or rebuilding, or
the Mortgagor shall have deposited such sufficient funds with the Mortgagee or
the Depository; and (c) the Mortgagee determines, in its reasonable discretion,
that (i) the Loan to Value Ratio (as defined in the Loan Agreement, and taking
into consideration the value of all of the Projects, as defined in the Loan
Agreement) is not greater than 55%, and (ii) the Debt Service Coverage Ratio (as
defined in the Loan Agreement, and taking into consideration the loss of income
resulting from such damage or destruction as projected by the Mortgagee in its
reasonable discretion) is not less than 1.40:1.0. Notwithstanding the foregoing,
if an event has occurred and is continuing that with the passage of time or the
giving of notice, or both, would constitute an Event of Default but the same has
not yet matured into an Event of Default, then, if the conditions set forth in
the foregoing clauses (b) and (c) have been or will be, in the Mortgagee's
reasonable judgment, satisfied, the Mortgagee shall not

elect either option (i) or (iii) unless such event shall have matured into an
Event of Default and, unless and until such event shall have so matured into an
Event of Default or such event has been cured or shall otherwise cease to exist,
the Mortgagee (or the Depository) shall not release any such insurance proceeds
or Award and the same shall be held until an Event of Default occurs or the
Default has been cured or shall otherwise cease to exist.

     2.5.7. Any such insurance proceeds (other than the proceeds of the rent
insurance policy, which shall be paid as provided in SECTION 2.5.8 below) or
Award which are to be applied to restoration, replacement or rebuilding of the
Mortgaged Premises shall, after payment or reimbursement to the Mortgagee of all
reasonable costs and expenses of the Mortgagee in collecting such proceeds or
Award, be applied upon satisfaction of the following provisions and conditions:

          (a) If the damage be of such nature as to require the Mortgagor to
     construct a replacement for, or to alter in any material or substantial
     way, the damaged or destroyed items, the Mortgagor shall, before commencing
     any such work, submit copies of the plans and specifications therefor to
     the Mortgagee for the Mortgagee's approval, such approval to not be
     unreasonably withheld or delayed.

          (b) If after payment or reimbursement to the Mortgagee of all costs
     and expenses of the Mortgagee in collecting such insurance proceeds or
     Award, the aggregate insurance proceeds or Award received by reason of any
     single instance of such damage or destruction or condemnation, as the case
     may be, shall be $200,000 or less such insurance proceeds or Award shall be
     paid to the Mortgagor, which shall hold all amounts so received in trust
     for application first to pay the entire cost of restoring, repairing,
     rebuilding or replacing the damaged or destroyed items, before any portion
     of such proceeds may be used or applied for any other purpose. If the
     aggregate net insurance proceeds or Award by reason of any single instance
     of such damage or destruction or condemnation, as the case may be, shall be
     more than $200,000 such sums shall be held and disbursed by Fleet Bank,
     National Association or, if this Mortgage is held by another financial
     institution, by such financial institution or, if this Mortgage is not held
     by a financial institution, by a financial institution selected by the then
     Mortgagee (the holder of such

     monies, the "Depository") in accordance with the following provisions of
     this SECTION 2.5.7.

          (c) The Mortgagee shall have received as to each such disbursement a
     certificate of the Mortgagor (i) requesting the payment of a specified
     amount of such insurance or condemnation proceeds; (ii) describing in
     reasonable detail the work and materials applied to the restoration,
     replacement or rebuilding of the damaged, destroyed or taken Improvement,
     or Building Service Equipment and/or Furnishings located therein, since the
     date of the last such certificate; (iii) stating that the requested amount
     does not exceed the cost of such work and materials; and (iv) stating that
     a request for payment for such work and materials has not previously been
     made, accompanied by:

               1. a certificate of an independent engineer or architect
          designated by the Mortgagor, who shall have been approved in writing
          by the Mortgagee (such approval not to be unreasonably withheld),
          stating (i) that the work and materials described in the accompanying
          certificate of the Mortgagor were satisfactorily performed and
          furnished and were necessary, appropriate or desirable to the
          restoration, replacement or rebuilding of the damaged, destroyed or
          taken Improvement, or Building Service Equipment and/or Furnishings;
          (ii) that the amount specified in such certificate of the Mortgagor
          does not exceed the reasonable cost of such work and materials; and
          (iii) the additional amount, if any, required to complete the
          restoration, replacement or rebuilding of the damaged, destroyed or
          taken Improvement, Building Service Equipment and/or Furnishings; and

               2. evidence reasonably satisfactory to the Mortgagee (i) that
          there exists no filed or recorded lien, or lien notice, or encumbrance
          or charge in respect of all or any part of the Mortgaged Premises that
          is prior to or on a parity with the lien of this Mortgage, except as
          may be permitted in the Permitted Encumbrances; (ii) that neither the
          Mortgaged Premises nor any part thereof is subject to any recorded or
          filed mechanic's, laborer's, materialman's or any similar lien,
          encumbrance or charge; and (iii) that none of the Building Service
          Equipment and Furnishings provided in

          connection with such restoration, replacement or rebuilding is subject
          to any security interest other than in favor of the Mortgagee;

     Upon satisfaction of the conditions set forth herein, the Mortgagee shall
pay to the Mortgagor the amount of such insurance or condemnation proceeds
requested in such certificate of the Mortgagor or consent to the Depository's
payment thereof, as the case may be; provided, however, that in no event shall
the balance of insurance or condemnation proceeds held by the Mortgagee and the
Depository be reduced below the amount specified in such certificate of the
independent engineer or architect as the amount required to complete the
restoration, replacement or rebuilding of the damaged, destroyed or taken
Improvement, Building Service Equipment and/or Furnishings. Each such payment,
whether made by the Mortgagee or the Depository, shall be held by the Mortgagor
in trust and shall be used solely for the payment of the cost of the work and
materials described in the certificate of the the Mortgagor, or if such cost or
any part thereof has theretofore been paid by the Mortgagor out of its own
funds, then for the reimbursement to the Mortgagor of any such cost or part
thereof paid by it. Any balance of insurance or condemnation proceeds held by
the Mortgagee after the completion of the restoration, replacement or rebuilding
and payment of all costs incurred in connection therewith, to be evidenced by a
certificate to such effect of such independent engineer or architect delivered
to the Mortgagee, shall, if no Event of Default shall have occurred and be
continuing, be released to the Person lawfully entitled thereto. Notwithstanding
the foregoing, if the Mortgagor needs to make deposits with or payments to
contractors prior to the work being performed, if the Mortgagee is otherwise
obligated to allow funds to be used to rebuild or restore, the Mortgagee agrees
that it will not unreasonably withhold or delay its consent to the Mortgagor's
request that such deposits or advances payments be allowed.

     2.5.8. All proceeds of rent insurance payable as a result of the occurrence
of any fire or other casualty which affects the Mortgaged Premises, or any part
thereof, shall be paid to the Mortgagee or, if the Mortgagee is not a financial
institution, the Depository. The Mortgagee or the Depository, as the case may
be, if it shall receive such proceeds, shall hold such proceeds in trust if
permitted under law, and in an account bearing interest (payable to or for
account of the Mortgagor), and shall apply or cause such proceeds (including any
net interest thereon) to be applied to the payment of those items

                                     - 19 -

referred to in SECTION 2.5.1(f) which become, and as they become, due and
payable from and after the date of the occurrence of such damage or loss, until
the completion of the necessary restoration or replacement by the Mortgagor or
until the exhaustion of such proceeds (including any interest thereon),
whichever first occurs. Upon completion of such restoration or replacement, any
balance of such rent insurance proceeds, together with the interest thereon, if
any, not theretofore applied as provided herein, in the hands of the Mortgagee
or the Depository, as the case may be, shall, provided that no Event of Default
shall have occurred and be continuing, be paid to the Person lawfully entitled
thereto.

     2.5.9. Nothing in this SECTION 2.5 contained shall (i) relieve the
Mortgagor of its duty to repair, restore, rebuild or replace the Improvements,
Building Service Equipment and/or Furnishings following damage or destruction by
fire or other casualty or taking in the event that no Award or an inadequate
Award or that no or inadequate proceeds of insurance are available to defray the
cost of such repairing, restoring, rebuilding or replacement (provided, however,
the Mortgagor shall be permitted to receive the insurance proceeds upon
satisfaction of the conditions set forth herein provided, in addition, that all
of the Insurance or Award Conditions have been and remain satisfied), or (ii)
relieve the Mortgagor of its obligation to pay principal and interest and to
make all other payments required by the Note, the Loan Agreement and this
Mortgage subsequent to the occurrence of any fire or other casualty, or taking,
except if, and to the extent that, any proceeds of rent insurance are applied by
the Mortgagee in accordance with SECTION 2.5.8 to such required payments.

     2.5.10. If, while any insurance proceeds or Award is being held by the
Mortgagee or the Depository, an Event of Default shall occur and be continuing,
the Mortgagee shall be entitled to receive and apply all such insurance proceeds
or Award in reduction of the indebtedness and other obligations secured by this
Mortgage, in such order and respective amounts, as the Mortgagee in its
discretion shall determine.

     2.6. To Comply with Laws.

     2.6.1. The Mortgagor, at its own expense, will promptly cure all violations
of law affecting the Mortgaged Premises, or any part thereof, and/or the use and
operation thereof and will promptly comply, or cause to be complied with, all
present and future Legal Requirements. 

                                     - 20 -

However, the Mortgagor shall have the right, after prior notice to the
Mortgagee, to contest by appropriate legal proceedings, diligently conducted in
good faith, the validity or application of any Legal Requirement if and so long
as the Mortgagor shall promptly furnish to the Mortgagee a certificate to such
effect showing the steps taken to comply with such provisions, provided that:

          (a) if by the terms of any such Legal Requirement, compliance
     therewith pending the prosecution of any such proceeding may be delayed
     legally without incurring any lien, charge or liability of any kind against
     the Mortgaged Premises, or any part thereof, and without subjecting the
     Mortgagor or the Mortgagee to any liability, civil or criminal, for failure
     so to comply therewith, the Mortgagor may delay compliance therewith until
     the final determination of any such proceeding; and

          (b) if any lien, charge or civil liability would be incurred by reason
     of any such delay, the Mortgagor nevertheless, on the prior written consent
     of the Mortgagee, such consent not to be unreasonably withheld, may contest
     and delay compliance with the Legal Requirement, provided that such delay
     would not subject the Mortgagee to criminal liability and the Mortgagor (i)
     furnishes to the Mortgagee security reasonably satisfactory to the
     Mortgagee against loss or injury by reason of such contest or delay and
     (ii) prosecutes the contest with due diligence.

     2.6.2. Notwithstanding the provisions of SECTION 2.6.1, if any delay in
compliance with any Legal Requirement shall, in the reasonable judgment of the
Mortgagee, place all or any part of the Mortgaged Premises in imminent danger of
being forfeited or lost, the Mortgagor shall, upon written notice from the
Mortgagee, immediately comply with such Legal Requirement.

     2.6.3. The Mortgagor will use and permit the use of the Mortgaged Premises
only in accordance with the material requirements of any applicable licenses and
permits issued by Governmental Authorities.

     2.6.4. The Mortgagor will procure, pay for and maintain (or cause to be
procured, paid and maintained) all permits, licenses and other authorizations
required to be procured and maintained by the owners and operators of the
Mortgaged Premises for any then use of all or any part

                                     - 21 -

of the Mortgaged Premises then being made and for the lawful and proper
operation and maintenance thereof.

     2.7. Limitation on Alterations and Demolition.

     2.7.1. The Mortgagor shall not voluntarily demolish, replace or alter the
Mortgaged Premises, or any part thereof, or voluntarily make any addition
thereto, or voluntarily construct any additional improvements thereon, or suffer
any of the same to occur, whether structural or otherwise (collectively,
"change"), without the prior written consent of the Mortgagee, which consent
shall not be unreasonably withheld or delayed; provided, however, that if no
Event of Default is continuing and such change involves an estimated cost of
less than $100,000 and is non-structural or if no Event of Default is continuing
and such change is non-structural and is being made to prepare space for a Space
Tenant pursuant to a Space Lease entered into in accordance with the Loan
Agreement, then, in either of such events, the Mortgagee's consent shall not be
required; provided, further, however, that if any such change is required by
law, the Mortgagor may make such change with the prior written consent of the
Mortgagee, which consent the Mortgagee will not unreasonably withhold or delay.
As a condition to any consent under this SECTION 2.7.1, the Mortgagee may
require (a) that plans and specifications for the proposed work, prepared by a
reputable architect reasonably satisfactory to the Mortgagee, be submitted to
the Mortgagee for approval, and (b) that the Mortgagor obtain a payment and
performance bond or other security reasonably satisfactory to the Mortgagee in
form and amount reasonably satisfactory to the Mortgagee from the contractor or
subcontractor performing the work unless such work amounts to less than $200,000
in aggregate total cost. All work performed by or on behalf of the Mortgagor
shall be completed with all reasonable diligence and continuity, in a good and
workmanlike manner, and in compliance with all applicable Legal Requirements.
Unless, and to the extent that, the provisions of SECTION 2.7.2 be applicable,
no Building Service Equipment or Furnishings shall be removed from the Mortgaged
Premises during the course of any such work without prior notification to the
Mortgagee and unless provision is made for return or replacement on or prior to
the completion of the work. The provisions of this SECTION 2.7.1. shall apply to
any change made or required to be made by the Mortgagor in the course of
complying with any other of the provisions of this Mortgage. A duplicate set of
all plans and specifications required to be filed with any Governmental
Authority prior to, or at any time in connection with, any such alteration,
demolition or new construc-

tion shall be furnished to the Mortgagee. The Mortgagor will pay on demand the
reasonable expenses incurred by the Mortgagee in the review of plans and
specifications provided for in this Mortgage.

     2.7.2. The Mortgagor shall have the right, at any time and from time to
time, to remove and dispose of any item of Building Service Equipment or
Furnishings which may have become obsolete or unfit for use or which is no
longer useful in the operation of the Improvements, provided that the Mortgagor
promptly replaces such item with other Building Service Equipment or
Furnishings, free of superior title, liens or claims (other than in favor of the
Mortgagee) unless consent of the Mortgagee is first obtained, not necessarily of
the same character but of at least equal quality, value and usefulness in
connection with the operation and maintenance of the Mortgaged Premises,
provided, further, however, no removal of any item of Building Service Equipment
or Furnishings then having a fair market value of $50,000 or more shall be made
without the prior written consent of the Mortgagee, which consent will not be
unreasonably withheld or delayed. However, if by reason of technological or
other developments in the operation and maintenance of buildings and other
improvements of the general character of the Improvements or a change in the use
of the Mortgaged Premises or any part thereof, no replacement of the Building
Service Equipment or Furnishings so removed would be necessary or desirable for
the proper operation or maintenance of the Improvements, the Mortgagor shall not
be required to replace the item so removed.

     2.8. Limitation on Disposition of the Mortgaged Premises.

     2.8.1. Except as expressly set forth in this Mortgage or the Loan Agreement
(including, without limitation, SECTIONS 5.01 and 6.21 of the Loan Agreement),
the Mortgagor shall not directly or indirectly sell, assign, mortgage, alienate,
pledge or otherwise transfer or further encumber the Mortgaged Premises or any
part thereof or any interest therein or in any of the rents, profits or income
generated thereby, whether voluntarily, involuntarily, by operation of law or
otherwise, or lease all or any portion thereof or an undivided interest therein,
without the prior written consent of the Mortgagee. The foregoing events are
hereinafter referred as a "Transfer". Any transfer without prior written the
consent of the Mortgagee is an Event of Default.

     2.8.2. If there shall be a violation of the terms and provisions of SECTION
2.8.1, whether by the Mortgagor or any other person, in addition to all other
rights and remedies available to the Mortgagee under this Mortgage, the
Mortgagee shall have the option, by the giving of notice to the Mortgagor, of
declaring the entire unpaid principal balance of the Note, together with all
accrued and unpaid interest and all other sums and charges evidenced thereby or
payable pursuant to the Loan Agreement, immediately due and payable.

     2.9. Maintenance of Mortgaged Premises; Covenant Against Waste; Inspection
by the Mortgagee. The Mortgagor will not commit or permit waste on the Mortgaged
Premises and, at its expense, will keep and maintain the Improvements, the
Building Service Equipment and Furnishings in its (or their) present state of
repair and condition, reasonable wear and tear excepted, and, if improved, in
such improved state of repair and condition, reasonable wear and tear excepted;
provided, that this shall not limit the Mortgagor's other obligations hereunder,
such as compliance with laws. The Mortgagor shall do or cause to be done all
maintenance and make or cause to be made all repairs as may be required by the
landlord under any Space Lease. The Mortgagor will neither do nor permit to be
done anything to the Mortgaged Premises that may materially impair the value
thereof or which may violate any covenant, condition or restriction affecting
the Mortgaged Premises, or any part thereof, or which would effect any material
change therein or in the condition thereof that would increase the danger of
fire or other hazard arising out of the operation of the Mortgaged Premises.
Subject to the rights of Space Tenants, the Mortgagee, and its representatives
and agents, may enter and inspect the Mortgaged Premises at any time after
reasonable notice (which may be oral) during usual business hours, and the
Mortgagor shall, within thirty (30) days after demand by the Mortgagee (or
immediately upon demand in case of emergency), make such repairs, replacements,
renewals or additions, or perform such items of maintenance, to the Mortgaged
Premises as the Mortgagee may reasonably require in order to cause the Mortgaged
Premises to comply with the standards established in this SECTION 2.9.

     2.10. To Furnish Certificates; Other Reporting Requirements.

     2.10.1. The Mortgagor will, at its own expense, deliver to the Mortgagee,
within fifteen (15) days after written request, but no more frequently than once
per six (6) month period, a written statement executed by the

Mortgagor, in recordable form, setting forth to the best of the Mortgagor's
knowledge, the amount then unpaid upon the Note and secured by this Mortgage and
stating whether any offsets or defenses exist against the indebtedness secured
hereby; and, if any such offsets or defenses are alleged to exist, then the
factual basis and amount of such claimed offsets or defenses.

     2.10.2. The Mortgagor will, if requested by the Mortgagee, deliver to the
Mortgagee a certificate of an officer of the general partner of the Mortgagor or
of such general partner's general partner, to the effect that he is familiar
with this Mortgage and the other Security Documents, has reviewed the affairs of
the Mortgagor, and to the best of his knowledge and belief there exists no Event
of Default and no act or event has occurred or exists which with notice or lapse
of time or both could become such an Event of Default, or if any such event or
Event of Default exists, specifying it and what action the Mortgagor is taking
to cause it to be remedied.

     2.11. After-Acquired Property. All right, title and interest of the
Mortgagor in and to all improvements, betterments, renewals, substitutes and
replacements of, and all additions and appurtenances to, the Mortgaged Premises
hereafter acquired, constructed, assembled or placed on the Mortgaged Premises,
immediately upon such acquisition, construction, assembly or placement, as the
case may be, and in each such case without any further mortgage, conveyance or
assignment or other act of the Mortgagor, shall become subject to the lien of
this Mortgage as fully and completely, and with the same effect, as though now
owned by the Mortgagor and specifically described in the granting clauses
hereof; and at any time and from time to time the Mortgagor, on demand, will
execute, acknowledge and deliver to the Mortgagee any and all such further
assurances, mortgages, conveyances or assignments as the Mortgagee may
reasonably require to further evidence, confirm and perfect the provisions of
this SECTION 2.11.

     2.12. Further Assurances. The Mortgagor shall, at its sole cost and without
expense to the Mortgagee, on demand, do, execute, acknowledge and deliver all
and every such further acts, deeds, conveyances, mortgages, assignments, notices
of assignment, transfers and assurances as the Mortgagee shall from time to time
reasonably require for better assuring, conveying, assigning, transferring and
confirming unto the Mortgagee the property and rights hereby mortgaged or
assigned or intended now or hereafter so to be, or which the Mortgagor may be or
may hereafter become bound

to convey, mortgage or assign to the Mortgagee, or for carrying out the
intention or facilitating the performance of the terms of this Mortgage, or for
filing, registering or recording this Mortgage.

     2.13. Recorded Instruments. The Mortgagor will promptly perform and
observe, or cause to be performed and observed, all of the terms, covenants and
conditions of all instruments of record affecting the Mortgaged Premises (other
than non-consensual encumbrances hereafter affecting the Mortgaged Premises, the
validity or enforceability of which the Mortgagor is contesting in accordance
with this Mortgage) where non-compliance therewith affects the security of this
Mortgage or imposes any duty or obligation upon the Mortgagor or any Space
Tenant. The Mortgagor shall do or cause to be done all things reasonably
required to preserve intact and unimpaired and to renew any and all
rights-of-way, easements, grants, appurtenances, privileges, licenses,
franchises and other interests and rights in favor of or constituting any
portion of the Mortgaged Premises. The Mortgagor will not, without the prior
written consent of the Mortgagee, which consent shall not be unreasonably
withheld or delayed, initiate, join in or consent to any private restrictive
covenant or other public or private restriction as to the use of all or any
portion of the Mortgaged Premises. The Mortgagor will, however, comply with all
lawful restrictive covenants and zoning ordinances and other public or private
restrictions affecting all or any portion of the Mortgaged Premises.


                                  ARTICLE III.

                                  Condemnation


     3.1. Notice of Taking. The Mortgagor shall promptly notify the Mortgagee if
the Mortgagor receives notice of the institution of any proceeding or
negotiations for the taking of the Mortgaged Premises, or any part thereof,
whether for permanent or temporary use and occupancy in condemnation or by the
exercise of the power of eminent domain or by agreement of interested parties in
lieu of such condemnation (all the foregoing called a "taking"); shall keep the
Mortgagee currently advised, in detail, as to the status of such proceedings or
negotiations and will promptly give to the Mortgagee copies of all notices,
pleadings, judgments, determinations and other papers received or delivered by
the Mortgagor in connection with any such proceedings. The Mortgagee shall have
the right to



                                     - 26 -

appear and participate in such proceedings and may be represented by counsel.
The Mortgagor will not, without the Mortgagee's prior written consent, which
consent shall not be unreasonably withheld or delayed, enter into any agreement
for the taking of the Mortgaged Premises, or any part thereof, with anyone
authorized to acquire the Mortgaged Premises by eminent domain or in
condemnation.

     3.2. Condemnation Award. If the Mortgaged Premises shall be the subject of
a taking the Mortgagee shall be entitled to and shall receive the total of such
portion of all awards made that shall be allowed to the Mortgagor with respect
to all the right, title and interest of the Mortgagor in and to the Mortgaged
Premises (the award made in any total, partial or temporary taking is herein
called the "Award"), provided that the obligations of the Mortgagor to perform
the terms, covenants and conditions of this Mortgage, if any, affected by such
taking shall continue unimpaired until the actual vesting of title in such
proceeding and the actual receipt by the Mortgagee of the Mortgagor's share of
the entire Award resulting from such taking.

     3.3. Application of Award. The Mortgagee shall have the option of treating
a total taking or a substantial taking (as hereinafter defined) as an Event of
Default and of accelerating the entire indebtedness secured hereby, in which
event it shall apply the Mortgagor's entire Award in reduction of such
indebtedness (including principal, interest and other sums secured hereby, in
such order as the Mortgagee may determine) and shall turn over any balance
remaining, if any, to the Person lawfully entitled thereto; or if the Mortgagee
shall not so elect to accelerate the indebtedness and apply the Award thereto,
then the total Award shall, regardless of amount, be deposited with the
Mortgagee or with the Depository, the Mortgagor hereby agreeing to elect that
such proceeds be held and disbursed by the Depository in accordance with
SECTIONS 2.5.6, 2.5.7, 2.5.8, 2.5.9 and 2.5.10 hereof for restoration required
to be made by the Mortgagor. If there be a partial taking, the net proceeds of
the Award shall be deposited with the Mortgagee and applied by the Mortgagee in
accordance with the provisions of SECTIONS 2.5.6, 2.5.7, 2.5.9 and 2.5.10.
Any Award remaining after the completion of such restoration, replacement or
rebuilding shall be applied in reduction of the indebtedness (including
principal, interest and other sums secured hereby) in such order as the
Mortgagee shall determine. A partial taking is substantial only if it materially
decreases the fair market value of the Mortgaged Premises and the remainder of
the Mortgaged

Premises cannot be restored to an economically viable whole.


     3.4. Temporary Taking. If any Award payable to the Mortgagor on account of
a taking for temporary use or occupancy is made in a lump sum or is payable
other than in equal monthly installments, the Mortgagor shall pay over such
Award to the Depository and such Award shall be applied to installments of
Impositions and of principal and interest and all other charges secured by this
Mortgage or due under the Note, the Loan Agreement, or the other Security
Documents as and when the same become due and payable. Any unapplied portion of
such Award held by the Depository when such taking ceases or expires (if no
Event of Default has then occurred and is continuing), or after the indebtedness
secured by this Mortgage or due under the Loan and Security Documents shall have
been paid in full, shall be paid to the Person lawfully entitled thereto.

     3.5. The Mortgagor's Obligation to Restore. If all available proceeds of
the Award are made available to the Mortgagor for restoration, replacement or
rebuilding pursuant hereto, the Mortgagor shall be obligated promptly to
restore, replace, rebuild or alter any Improvements or Building Service
Equipment affected by a taking so as to restore the Mortgaged Premises to an
economically viable whole, all without regard to the adequacy of the proceeds of
an Award, if any, made available to the Mortgagor.


                                   ARTICLE IV.

                   Assignment of Space Leases, Rents, Profits
                   and Other Income as Further Security, Etc.


     4.1. Assignment of Space Leases, Rents, Issues and Profits. Subject to the
Mortgagor's rights herein, including those set forth in SECTION 4.3.2 below, the
Mortgagor hereby absolutely, presently and irrevocably transfers, assigns and
sets over unto the Mortgagee all right, title and interest of the Mortgagor in
and to all Space Leases, if any, now or hereafter entered into with respect to
all or any part of the Mortgaged Premises, and all renewals, extensions,
subleases or assignments thereof, and all other occupancy agreements (written or
oral), by concession, license or otherwise, together with all of the rents,
income, receipts, revenues, issues and profits arising therefrom (the
"Collateral").

     4.2. The Mortgagor's Covenants Regarding Space Leases.

     4.2.1. Without the prior consent and approval of the Mortgagee in each
instance, the Mortgagor will not (a) assign, pledge, hypothecate or otherwise
encumber any of the Space Leases or the rents, income, issue and profits of the
Mortgaged Premises; or (b) enter into any Space Leases affecting the Mortgaged
Premises or any part thereof, unless such Space Lease is expressly subordinate
to the lien of this Mortgage and to any consolidation, extension, renewal,
recasting or refinancing hereof and the Space Lease provides, in substance, that
in the event of enforcement by the Mortgagee of the remedies provided for by law
or by this Mortgage, each Space Tenant shall, at the option of the Mortgagee,
enter into a agreement with the Mortgagee which shall provide, among other
things, that (i) such Space Tenant shall attorn to any person succeeding to the
interest of the Mortgagor as a result of such enforcement and shall recognize
such successor in interest as landlord under such Space Lease without change in
the terms or other provisions thereof, (ii) such successor shall not be bound by
any payment of rent or additional rent for more than one (1) month in advance or
any amendment or modification of any such Space Lease made without the
Mortgagee's written consent, and (iii) such successor shall not disturb the
possession of the Space Tenant provided certain conditions (as determined by the
Mortgagee) have been satisfied, including, without limitation, that the Space
Tenant shall not be in default under the terms of the Space Lease; or (c) enter
into any Space Leases without the prior written consent of the Mortgagee unless
permitted in SECTION 6.21 of the Loan Agreement.

     4.2.2. The Mortgagor further represents, warrants, covenants and agrees
that:

          (a) To the best of its knowledge, each Space Lease is (or, when
     executed, will be) a valid and legally enforceable obligation of the
     parties thereto, in full force and effect.

          (b) With respect to each Space Lease and the Space Tenant security
     deposits thereunder, any and/or all of such security deposits shall be held
     as required by the Space Lease but in no event in a manner other than that
     required by law.

          (c) The Mortgagor shall, at its sole cost and expense, keep, observe,
     perform and discharge, 


                                     - 29 -

     duly and punctually, all and singular the material obligations, terms,
     covenants, conditions, representations and warranties of each Space Lease
     on the part of the Mortgagor to be kept, observed, performed and
     discharged.

          (d) (i) Except as herein in this clause (i) expressly provided, the
     Mortgagor shall, at its sole cost and expense, maintain the Space Leases in
     full force and effect; the Mortgagor will not waive its rights under or
     materially modify, change, supplement, alter or amend ("Change"), nor shall
     the Mortgagor surrender (whether partial or total), terminate, cancel or
     subordinate, any of the Space Leases or enter into any Backlease (whether
     through an Affiliate or otherwise), and any such attempted Change,
     surrender, termination, cancellation or subordination or Backlease shall be
     void, unless, in each case, the prior written consent thereto of the
     Mortgagee shall have been obtained. Notwithstanding the foregoing, the
     Mortgagor may (x) terminate any Space Lease under 10,000 rentable square
     feet as a result of a default by the tenant under such Space Lease and (y)
     consent to any sublease or assignment of any Space Lease under 10,000
     rentable square feet provided (aa) such termination is being effected in
     the ordinary course of the Mortgagor's business, (bb) no Event of Default
     then exists and no event has occurred that with the passage of time or the
     giving of notice or both would constitute an Event of Default, and (cc) the
     Mortgagee determines, in its reasonable discretion, that upon the
     effectiveness of such termination, assignment or sublease (i) the Loan to
     Value Ratio (as defined in the Loan Agreement, and taking into
     consideration the value of all of the Projects, as defined in the Loan
     Agreement) is not greater than 55%, and (ii) the Debt Service Coverage
     Ratio (as defined in the Loan Agreement, and taking into consideration the
     loss of income resulting from such termination, assignment or sublease, as
     projected by the Mortgagee in its reasonable discretion) is not less than
     1.40:1.0. A material Change shall include but not be limited to any
     material Change in the amount or time of payment of the rent or additional
     rent, the length of term or square footage of the premises under any Space
     Lease or any other Change which would materially adversely affect the
     Mortgagor's rights under the Space Lease, or would affect the Mortgagee's
     rights under the Space Lease or the value of the Space Lease as collateral
     security for the indebtedness.

               (ii) The Mortgagor shall, at its sole cost and expense, enforce
          the Space Leases in accordance with their terms; and shall appear in
          and defend any action or proceeding arising to which it is a party
          under or in any manner connected with any of the Space Leases.

          (e) The Mortgagor shall deliver to the Mortgagee a copy of each notice
     of default sent or received by it relating in any way to any Space Lease
     promptly upon, but in any event within five (5) business days after, its
     sending or receipt thereof.

     4.3. The Mortgagor's Rights and Powers.

     4.3.1. The Mortgagor hereby irrevocably, in the name of the Mortgagor or
otherwise, authorizes and empowers the Mortgagee, and assigns and transfers unto
the Mortgagee, and constitutes and appoints the Mortgagee its true and lawful
attorney-in-fact, coupled with an interest and as its agent, irrevocably, with
full power or substitution for it and in its name, but solely for the following
purposes: (i) to exercise and enforce every right, power, remedy, authority,
option and privilege of the Mortgagor under the Space Leases, and as such
attorney-in-fact, the Mortgagee may subordinate, terminate, cancel or modify the
Space Leases, accept the surrender of the Space Leases, give any notice, take
any action resulting in such subordination, termination, cancellation,
modification or surrender, give any authorization, furnish any information, make
any demands, execute any instruments and take any and all other action on behalf
of and in the name of the Mortgagor which in the opinion of the Mortgagee may be
necessary or appropriate to be given, furnished, made, exercised or taken by the
Mortgagor under the Space Leases in order to comply therewith, to perform the
conditions thereof or to prevent or remedy any default by the Mortgagor
thereunder or to enforce any of the Mortgagor's rights and remedies there-under,
and (ii) to ask, require, demand, receive and collect and give acquittances for
the Income (as hereinafter defined), and on nonpayment thereof to sue for,
recover and receive the same, and on payment thereof to give sufficient
releases, receipts, discharges and acquittances thereof; to endorse any checks
or other instruments or orders in connection therewith and to file any claims or
take any action or institute any proceedings which the Mortgagee may deem to be
necessary or advisable; provided, however, that the power provided for in this
sentence may not be exercised by the Mortgagee unless an Event of Default shall
have occurred and be continuing. "Income" shall mean all


                                     - 31 -

deposits, rents, issues, profits, revenues, royalties, and other revenue
producing arrangements, whether written or oral, and all monetary benefits of,
and/or derived from, and/or sums payable under and by virtue of the Space Leases
and/or the Premises.

     4.3.2. So long as there shall not have occurred and then be continuing any
Event of Default and until such right of the Mortgagor is terminated by the
Mortgagee as provided in SECTION 4.3.3, the Mortgagee will not exercise its
rights pursuant to SECTION 4.3.1, and, notwithstanding anything in SECTION 4.3.1
to the contrary, the Mortgagor shall have the right (but limited as hereinafter
provided) to exercise all of its rights under the Space Leases, including,
without limitation, to collect and receive all rents, income, receipts,
revenues, issues and profits arising therefrom, provided that the Mortgagor
shall at all times comply with, observe and perform, in the exercise of such
right, all of the provisions of this Mortgage and the other Security Documents
applicable to the Space Leases; provided, further, that no action shall be taken
or failed to be taken by the Mortgagor which would impair the Collateral or any
other collateral security for the Obligations provided for in the Security
Documents.

     4.3.3. The Mortgagee, upon the occurrence and during the continuance of an
Event of Default, at its option and upon written notice to the Mortgagor, shall
have the right to terminate the right of the Mortgagor to exercise its rights
under the Space Leases, and, thereupon, in addition, the Mortgagee, at any time
thereafter, at its option, shall have the complete right, power and authority
hereunder to exercise and enforce all rights, powers, remedies, authority,
options and privileges of the Mortgagor under the Space Leases in the name of
the Mortgagor or the Mortgagee, to enforce all obligations of the other parties
to the Space Leases and to exercise and enforce all of its rights and remedies
hereunder and under law not exercisable prior to an Event of Default.

     4.3.4. The Mortgagor does hereby direct each and all of the Space Tenants
under the Space Leases and all contractual obligors of the Mortgagor to pay any
Income to the Mortgagee upon written demand for payment thereof by the Mortgagee
without further inquiry. It is understood and agreed, however, that no such
demand shall be made unless an Event of Default shall have occurred and be
continuing. No such Space Tenant or obligor shall be obliged to account to the
Mortgagor for any amounts paid to the Mortgagee by reason of any payment made to
the Mortgagee pursuant to such


                                     - 32 -

demand and, upon any such payment to the Mortgagee, shall be pro tanto released
from their obligations to the Mortgagor with respect to such payment. Each Space
Tenant shall be permitted to rely on any communication from the Mortgagee
pursuant hereto, and under no circumstances shall such Space Tenant be obligated
to the Mortgagor for any payments made to the Mortgagee hereunder. Until such
demand is made, the Mortgagor is authorized to collect or enforce or continue
collecting or enforcing such Income in accordance with the provisions of this
Mortgage.

     4.3.5. The Mortgagee shall not have any duty as to the collection or
protection of the Collateral or any income thereon or payments with respect
thereto, or as to the preservation of any rights pertaining thereto beyond the
safe custody of any thereof actually in its possession. In no instance shall the
Mortgagee be responsible to lessees for payment of interest upon, or return of,
any lease security deposits, except as provided by law or as provided in the
leases and then only if and to the extent that such deposits are received by the
Mortgagee. The Mortgagor hereby waives notice of acceptance hereof, and except
as otherwise specifically provided herein or required by provision of law which
may not be waived, hereby waives any and all notices or demands with respect to
any exercise by the Mortgagee of any rights or powers which it may have or to
which it may be entitled with respect to the Collateral.

     4.3.6. The Mortgagor hereby irrevocably constitutes and appoints the
Mortgagee as the true and lawful attorney-in-fact of the Mortgagor, which
appointment is coupled with an interest, with full power of substitution, to
proceed from time to time in the Mortgagor's name in any statutory or
non-statutory proceeding affecting the Mortgagor or any Collateral, and the
Mortgagee or its nominee may (i) execute and file proof of claim for the full
amount of any Collateral and vote such claims for the full amount thereof (A)
for or against any proposal or resolution, (B) for a trustee or trustees or for
a receiver or receivers or for a committee of creditors and/or (C) for the
acceptance or rejection of any proposed arrangement, plan of reorganization,
composition or extension, and the Mortgagee or its nominee may receive any
payment or distribution and give acquittance therefor and may exchange or
release Collateral; (ii) endorse any draft or other instrument for the payment
of money, execute releases and negotiate and enter into settlements; and (iii)
execute all such other documents or instruments as may be necessary or expedient
to be executed by the Mortgagor for any of the purposes of this Mortgage;
provided, however, that the power

provided for in this sentence may be exercised by the Mortgagee only while an
Event of Default is continuing. The Mortgagee shall have no duty to exercise any
of the aforesaid rights, privileges or options and shall not be responsible for
any failure to do so or delay in so doing.

     4.4. Remedies and Entry Upon Default.

     4.4.1. So long as no Event of Default shall have occurred and be
continuing, the Mortgagor shall have the right to collect (but not more than one
(1) month in advance) and retain all of the rents, gross receipts and other
payments, if any, from the Space Leases and from the Mortgaged Premises
generally, and the Mortgagee agrees that customary initial rent payments,
security deposits and reimbursements by a Space Tenant to the Mortgagor on
account of alterations made by the Mortgagor for the benefit of the Space Tenant
are permissible advance payments by the Space Tenant.

     4.4.2. Upon any Event of Default, the Mortgagee may, but shall not be
obligated to:

          (a) terminate the rights of the Mortgagor referred to in SECTION 4.3
     hereof and exercise all of the powers, rights and remedies provided for in
     SECTION 4.3 hereof, including those to be exercised only from and after an
     Event of Default;

          (b) at any time and from time to time, without notice to, or assent

     any present or future contract obligors; and/or

          (d) pay, in such order as the Mortgagee in its sole discretion shall
     determine, from and out of the Income collected in connection with the
     Premises and/or the Collateral or any part or parts thereof or from or out
     of any other funds (less the expense of collection, including reasonable
     attorneys' fees and disbursements), any taxes, assessments, water rates,
     sewer rates, or other government or other charges levied, assessed or
     imposed against the Premises or any part or part thereof, and also any and
     all other charges, costs and expenses which the Mortgagee deems necessary
     or advisable to pay in respect of the management or operation of the
     Premises, including, without limitation, the costs of insurance policies,
     repairs and alterations, commissions for renting the Premises or any part
     or parts thereof, legal expenses in enforcing claims, preparing papers or

     nor any other action taken by the Mortgagee in connection therewith, shall
     cure or waive any default hereunder or waive or modify any notice thereof
     or notice of acceleration of the Note theretofore given by the Mortgagee.

     4.4.3. If an Event of Default shall have occurred and be continuing, a
notice in writing by the Mortgagee to the Space Tenants under the Space Leases
advising them that the Mortgagor has defaulted hereunder and requesting that all
future payments of rent, additional rent or other charges under the Space Leases
be made to the Mortgagee (or its agent) shall be construed as conclusive
authority to such Space Tenants that such payments are to be made to the
Mortgagee (or its agent). Each Space Tenant shall be fully protected in making
such payments to the Mortgagee (or its agent) and be given full credit against
its obligations under the applicable Space Lease to the extent of payments made
to the Mortgagee (or its agent) pursuant to any such notice; and the Mortgagor
hereby irrevocably constitutes and appoints the Mortgagee the attorney-in-fact
and agent of the Mortgagor, coupled with an interest, for the purpose of

and against any and all liability, loss or damage which the Mortgagee may incur
by reason of any act of the Mortgagee under this Mortgage, other than as a
result of the Mortgagee's willful misconduct or gross negligence and other than
as a result of the Mortgagee's misconduct or negligence after the Mortgagee has
taken possession of the Premises. Should the Mortgagee (i) incur any such
liability, loss or damage by reason of this Mortgage and which is covered by the
foregoing indemnity, or in defense against any such claims or demands, or (ii)
perform any acts or covenants on the part of the Mortgagor to be performed under
the Space Leases, or (iii) pay for the account of the Mortgagor (other than from
Income or from funds delivered to the Mortgagee by the Mortgagor to be held in
trust for such purpose), any and all sums, costs and expenses for the discharge
of taxes, assessments, water rents or other liens against the Collateral or any
part thereof, or on account of insurance premiums or repairs, and also any
amounts and expenses necessary to perform any

covenants and conditions to be performed on the part of the Mortgagor under the
Space Leases, the amount thereof, including costs, expenses and reasonable
attorneys' fees, together with interest thereon at the Involuntary Rate from the
date such expenses were paid by the Mortgagee to the date of payment to the
Mortgagee by the Mortgagor, shall be included in the Obligations secured by this
Mortgage, and the Mortgagor shall reimburse the Mortgagee therefor upon demand.

     4.5.2. The acceptance by the Mortgagee of this Mortgage, with all the
rights, powers, privileges and authority so created, shall not at any time or in
any event obligate the Mortgagee to appear in or defend any action or proceeding
relating to the Collateral, or to take any action hereunder or thereunder, or to
expend any money or incur any expenses or perform or discharge any obligation,
duty or liability under the Collateral.


                                   ARTICLE V.

                Security Agreement Under Uniform Commercial Code

     5.1. This Mortgage shall constitute a security agreement and fixture filing
within the meaning of the Uniform Commercial Code of the State (the "Code"), and
the Mortgagee shall be deemed to be the "secured party" (as that term is defined
in the Code). The Mortgagor hereby grants to the Mortgagee, as additional
collateral for the obligations under the Note and the other Obligations secured
hereby, a security interest in and to all of the Mortgaged Premises which are
considered or as shall be determined to be personal property or "fixtures" (as
defined in the Code), including, without limitation, the Building Service
Equipment, the Furnishings, the Payments and Intangibles, all books, records,
licenses and certificates of the Mortgagor relating to the Mortgaged Premises,
together with all replacements thereof, substitutions therefor or additions
thereto (said property being sometimes hereinafter referred to as the "Personal
Property"). The Mortgagor agrees that a security interest shall attach to the
Personal Property for the benefit of the Mortgagee to secure the indebtedness
evidenced by the Note and the other Obligations secured by this Mortgage and all
other sums and charges which may become due hereunder, thereunder or under any
of the other Security Documents. The Mortgagor hereby authorizes the Mortgagee
to file financing and continuation statements with respect to the Personal
Property without the signature of the Mortgagor, if permitted by the Code. In


                                     - 37 -

any event the Mortgagor covenants to execute such financing and continuation
statements as the Mortgagee may reasonably request. If an Event of Default shall
occur and be continuing, the Mortgagee, pursuant to the appropriate provisions
of the Code, shall have the option of proceeding as to both real and personal
property in accordance with its rights and remedies in respect of real property
under this Mortgage and the law of the State, in which event the default
provisions of the Code shall not apply. The Mortgagor agrees that, in the event
the Mortgagee shall elect to proceed with respect to the Personal Property
separately from the real property, unless a greater period shall then be
mandated by the Code, five (5) days notice of the sale of the Personal Property
shall be reasonable notice. The expenses of retaking, holding, preparing for
sale and selling incurred by the Mortgagee shall be assessed against the
Mortgagor and shall include, but not be limited to, the reasonable legal
expenses incurred by the Mortgagee. The Mortgagor agrees that it will not remove
or permit to be removed from the Mortgaged Premises any of the Personal Property
without the prior written consent of the Mortgagee except as set forth in
SECTION 2.7.2. All replacements, renewals and additions to the Personal Property
shall be and become immediately subject to the security interest of this
Mortgage and the provisions of this ARTICLE V. The Mortgagor warrants and
represents that all Personal Property now is free and clear of all liens,
encumbrances or security interests other than the Permitted Encumbrances, and
that all replacements of the Personal Property, substitutions therefor or
additions thereto, unless the Mortgagee otherwise consents, will be, free and
clear of liens, encumbrances or security interests of others.


                                   ARTICLE VI.

                         Events of Default and Remedies


     6.1. Events of Default. The whole of the outstanding Principal Amount (as
defined in the Note) and accrued interest evidenced by the Note shall, at the
option of the Mortgagee, become due upon the happening of an Event of Default;
provided, however, that upon the occurrence of a default specified in SECTIONS
5.01(f) or 5.01(g) of the Loan Agreement, or upon the occurrence of any other
default specified in any Loan Document (as defined in the Loan Agreement) where
provision is made for acceleration to occur automatically as a consequence
thereof, all sums owing to


                                     - 38 -

the Mortgagee thereunder shall automatically become immediately due and payable.

     6.2. Remedies.

     6.2.1. If an Event of Default shall occur and be continuing, the Mortgagee,
at its option, may exercise any or all of the following rights:

          (1) use the non-judicial Power of Sale which is hereby conferred under
     the terms of this Mortgage. Such Power of Sale shall be exercised by giving
     the Mortgagor Notice of Intent to Foreclose by Power of Sale and setting
     forth among other things, the nature of the breach(es) or default(s) and
     the action required to effect a cure thereof and the time period within
     which such cure may be effected all in compliance with Title 46 Oklahoma
     Statutes ss.ss. 40 et. seq. (Oklahoma Power of Sale Mortgage Foreclosure
     Act) effective November 1, 1986, as the same may be amended from time to
     time or other applicable statutory authority. If no cure is effected within
     the statutory time limits, the Mortgagee may accelerate the Indebtedness
     without further notice (the aforementioned statutory cure period shall run
     concurrently with any contractual provision for notice and/or cure period
     before acceleration of debt) and may then proceed in the manner and subject
     to the conditions of the above referenced statutes to send to the Mortgagor
     and other necessary parties a Notice of Sale and to sell and convey the
     Mortgaged Premises in accordance with the above referenced statute. The
     sale shall be made at one or more sales, as an entirety or in parcels, upon
     such notice, at such time and places, subject to all conditions and with
     the proceeds thereof to be applied all as provided in said Oklahoma Power
     of Sale Mortgage Foreclosure Act. No action of the Mortgagee based upon the
     provisions contained herein or contained in the Oklahoma Power of Sale
     Mortgage Foreclosure Act, including, without limitation, the giving of the
     Notice of Intent to Foreclose by Power of Sale or the Notice of Sale, shall
     constitute an election of remedies which would preclude the Mortgagee from
     pursuing judicial foreclosure before or at any time after commencement of
     the power of sale foreclosure procedure.

          (2) whether or not proceedings have commenced by the exercise of the
     power of sale above given, the Mortgagee or the holder or holders of any of
     the Indebtedness secured by the Mortgage, in


                                     - 39 -

FRK11625.A05

<PAGE>



     lieu of proceeding with the power of sale, (or in the event of homestead
     property where the Mortgagor has elected judicial foreclosure, as provided
     in the above referenced statutes) may at its (their) option (after any
     applicable contractual cure period has expired without such default being
     cured) declare the whole amount of the Indebtedness secured by this
     Mortgage remaining unpaid, immediately due and payable without notice, and
     proceed by suit or suits in equity or at law to foreclose this Mortgage.
     Appraisement of the Mortgaged Premises is hereby waived or not waived at
     the option of the Mortgagee, such option to be exercised at or prior to the
     time judgment is rendered in such judicial foreclosure. The Mortgaged
     Premises may be sold as one parcel or in such parcels as the Mortgagee may
     elect unless otherwise provided by law.

          (3) enter upon the Mortgaged Premises and take exclusive possession
     thereof and of all books, records and accounts relating thereto. If the
     Mortgagor remains in possession of all or any part of the Mortgaged
     Premises after an Event of Default and without the Mortgagee's prior
     written consent thereto, the Mortgagee may invoke any and all legal
     remedies to dispossess the Mortgagor, including specifically one or more
     actions for forcible entry and detainer, trespass to try title and writ of
     restitution. Nothing contained in the foregoing sentence shall, however, be
     construed to impose any greater obligation or any prerequisites to
     acquiring possession of the Mortgaged Premises after an Event of Default
     than would have existed in the absence of such sentence;

          (4) hold, lease, manage, operate or otherwise use or permit the use of
     the Mortgaged Premises, either itself or by other persons, firms or
     entities, in such manner, for such time and upon such other terms as the
     Mortgagee may deem to be prudent and reasonable under the circumstances
     (making such repairs, alterations, additions and improvements thereto and
     taking any and all other action with reference thereto, from time to time,
     as the Mortgagee shall deem necessary or desirable), and apply all rents,
     issues, income and profits and other amounts collected by the Mortgagee in
     connection therewith in accordance with the provisions set forth
     hereinbelow;

          (5) sell the Mortgaged Premises in the manner and form prescribed by
     law through

     foreclosure of the lien created pursuant to this Mortgage;

          (6) upon, or at any time after, commencement of foreclosure of the
     lien and security interest provided for herein or any legal proceedings
     hereunder, make application to a court of competent jurisdiction as a
     matter of strict right and without notice to the Mortgagor other than as
     specifically provided herein or in the other Security Documents or regard
     to the adequacy of the Mortgaged Premises for the repayment of the
     Indebtedness or to the solvency or insolvency of the Mortgagor, for
     appointment of a receiver of the Mortgaged Premises, and the Mortgagor does
     hereby irrevocably consent to such appointment. Any such receiver shall
     have all the usual powers and duties of receivers in similar cases,
     including the full power to rent, maintain and otherwise operate the
     Mortgaged Premises upon such terms as may be approved by the court, and
     shall apply such rents, issues, income and profits in accordance with the
     provisions set forth hereinbelow;

          (7) exercise any and all other rights, remedies and recourses granted
     under the Security Documents or now or hereafter existing in equity, at
     law, by virtue of statute or otherwise; and/or

          (8) exercise any and all remedies available to a secured party under
     the UCC in such order and in such manner as the Mortgagee in its sole
     discretion may determine; provided, however, that the expenses of retaking,
     holding, preparing for sale or the like, shall include reasonable
     attorneys' fees and other expenses of the Mortgagee and be secured by this
     Mortgage;

     6.2.2. The Mortgagee may adjourn from time to time any sale by it to be
made under or by virtue of this Mortgage by announcement at the time and place
appointed for such sale or for such adjourned sale or sales; and, except as
otherwise provided by any applicable provision of law, the Mortgagee, without
further notice or publication, may make such sale at the time and place to which
the same shall be so adjourned.

     6.2.3. Upon the completion of any sale or sales made by the Mortgagee under
or by virtue of this SECTION 6.2, the Mortgagee, or an officer of any court


                                     - 41 -

empowered to do so, shall execute and deliver to the accepted purchaser or
purchasers a good and sufficient instrument or instruments conveying, assigning
and transferring all estate, right, title and interest in and to the property
and rights sold. The Mortgagee is hereby irrevocably appointed the true and
lawful attorney of the Mortgagor, in its name and stead, to make all necessary
conveyances, assignments, transfers and deliveries of the Mortgaged Premises and
rights so sold and for that purpose the Mortgagee may execute all necessary
instruments of conveyance, assignment and transfer, and may substitute one or
more persons with like power, the Mortgagor hereby ratifying and confirming all
that its said attorney or such substitute or substitutes shall lawfully do by
virtue hereof. Nevertheless, the Mortgagor, if requested by the Mortgagee, shall
ratify and confirm any such sale or sales by executing and delivering to the
Mortgagee or to such purchaser or purchasers all such instruments as may be
advisable, in the judgment of the Mortgagee, for the purpose, and as may be
designated in such request. Any such sale or sales made under or by virtue of
this SECTION 6.2, whether made under the power of sale herein granted or under
or by virtue of judicial proceedings or of a judgment or decree of foreclosure
and sale, shall operate to divest all the estate, right, title, interest, claim
and demand whatsoever, whether at law or in equity, of the Mortgagor in and to
the properties and rights so sold, and shall be a perpetual bar both at law and
in equity against the Mortgagor and against any and all persons claiming or who
may claim the same, or any part thereof from, through or under the Mortgagor.

     6.2.4. In the event of any sale or sales made under or by virtue of this
SECTION 6.2 (whether made under the power of sale herein granted or under or by
virtue of judicial proceedings or of a judgment or decree of foreclosure and
sale), the entire principal of, and interest on, the Note, if not previously due
and payable, and all other sums required to be paid by the Mortgagor pursuant to
this Mortgage, immediately thereupon shall, anything in the Note or in this
Mortgage to the contrary notwithstanding, become due and payable.

     6.2.5. The purchase money, proceeds or avails of any sale or sales made
under or by virtue of this SECTION 6.2, together with any other sums which then
may be held by the Mortgagee under this Mortgage, whether under the provisions
of this SECTION 6.2, or otherwise, shall be applied as follows:

          First: To the payment of the costs and expenses of such sale,
     including reasonable compensation to the Mortgagee, its agents and counsel,
     and of any judicial proceedings wherein the same may be made, and of all
     expenses, liabilities and advances made or incurred by the Mortgagee under
     this Mortgage, together with interest at the Involuntary Rate on all
     advances made by the Mortgagee, and of all taxes, assessments or other
     charges, except any taxes, assessments or other charges subject to which
     the Mortgaged Premises shall have been sold.

          Second: To the payment of the whole amount then due, owing or unpaid
     upon the Note for principal and interest, with interest on the unpaid
     principal at the Involuntary Rate from and after the happening of any Event
     of Default from the due date of any such payment of principal until the
     same is paid.

          Third: To the payment of any other sums required to be paid by the
     Mortgagor pursuant to any provision of this Mortgage or of the Note.

          Fourth: To the payment of the surplus, if any, to whomsoever may be
     lawfully entitled to receive the same.

     6.2.6. Upon any sale or sales made under or by virtue of this SECTION 6.2,
whether made under the power of sale herein granted or under or by virtue of
judicial proceedings or of a judgment or decree of foreclosure and sale, the
Mortgagee may bid for and acquire the Mortgaged Premises or any part thereof and
in lieu of paying cash therefor may make settlement for the purchase price by
crediting upon the indebtedness secured by this Mortgage the net sales price
after deducting therefrom the expenses of the sale and the costs of the action
and any other sums which the Mortgagee is authorized to deduct under this
Mortgage.

     6.2.7. In case an Event of Default shall have happened and be continuing,
then, upon written demand of the Mortgagee, the Mortgagor will pay to the
Mortgagee the whole amount which then shall have become due and payable on the
Note, for principal or interest or both, as the case may be, and after the
happening of said Event of Default will also pay to the Mortgagee interest at
the Involuntary Rate on the then unpaid principal of the Note,

and the sums required to be paid by the Mortgagor pursuant to any provision of
this Mortgage or the Note, and in addition thereto such further amount as shall
be sufficient to cover the costs and expenses of collection, including
reasonable compensation to the Mortgagee, its agents and counsel and any
expenses incurred by the Mortgagee hereunder. In the event the Mortgagor shall
fail forthwith to pay such amounts upon such demand, the Mortgagee shall be
entitled and empowered to institute such action or proceedings at law or in
equity as may be advised by its counsel for the collection of the sums so due
and unpaid, and may prosecute any such action or proceedings to judgment or
final decree, and may enforce any such judgment or final decree against the
Mortgagor and collect, out of the property of the Mortgagor wherever situated,
as well as out of the Mortgaged Premises, in any manner provided by law, moneys
adjudged or decreed to be payable.

     6.2.8. Any moneys thus collected by the Mortgagee under this SECTION 6.2
shall be applied by the Mortgagee in accordance with the provisions of SECTION
6.2.5 hereof.

     6.2.9. After the happening of any Event of Default and immediately upon the
commencement of any action, suit or other legal proceedings by the Mortgagee to
obtain judgment for the principal of, or interest on, the Note and other sums
required to be paid by the Mortgagor pursuant to any provision of this Mortgage
or the Note, or of any other nature in aid of the enforcement of the Note or of
this Mortgage, the Mortgagor will (a) waive the issuance and service of process
and enter its voluntary appearance in such action, suit or proceeding and (b) if
required by the Mortgagee, consent to the appointment of a receiver or receivers
of all or part of the Mortgaged Premises and of any or all of the rents, issues
and profits of the Mortgaged Premises in respect thereof. After the happening of
any Event of Default and during its continuance, or upon the commencement of any
proceedings to foreclose this Mortgage or to enforce the specific performance
hereof or in aid thereof or upon the commencement of any other judicial
proceeding to enforce any right of the Mortgagee, the Mortgagee shall be
entitled, as a matter of right, if it shall so elect, without the giving of
notice to any other party and without regard to the adequacy or inadequacy of
any security for the indebtedness secured hereby, forthwith either before or
after declaring the unpaid principal of the Note to be due and payable, to the
appointment of such a receiver or receivers.

     6.2.10. Notwithstanding the appointment of any receiver, liquidator or
trustee of the Mortgagor, or of any of its property, or of the Mortgaged
Premises, or any part thereof, the Mortgagee shall be entitled to retain
possession and control of all property now or hereafter held under this
Mortgage.

     6.2.11. The Mortgagor will not at any time insist upon, or plead, or in any
manner whatever claim or take any benefit or advantage of any stay or extension
or moratorium law, any exemption from execution or sale of the Mortgaged
Premises or any part thereof, wherever enacted, now or at any time hereafter in
force, which may affect the covenants and terms of performance of this Mortgage,
nor claim, take or insist upon any benefit or advantage of any law now or
hereafter in force providing for the valuation or appraisal of the Mortgaged
Premises, or any part thereof, prior to any sale or sales thereof which may be
made pursuant to any provision herein, or pursuant to the decree, judgment or
order of any court of competent jurisdiction; nor, after any such sale or sales,
claim or exercise any right under any statute heretofore or hereafter enacted to
redeem the property so sold or any part thereof and the Mortgagor hereby
expressly waives all benefit or advantage of any such law or laws, and covenants
not to hinder, delay or impede the execution of any power herein granted or
delegated to the Mortgagee, but to suffer and permit the execution of every
power as though no such law or laws had been made or enacted.

     6.2.12. During the continuance of any Event of Default and pending the
exercise by the Mortgagee of its right to exclude the Mortgagor from all or any
part of the Premises, the Mortgagor agrees to pay the fair and reasonable rental
value for the use and occupancy of the Premises or any portion thereof which are
in its possession for such period and, upon default of any such payment, will
vacate and surrender possession of the Premises to the Mortgagee or to a
receiver, if any, and in default thereof may be evicted by any summary action or
proceeding for the recovery of possession of premises for non-payment of rent,
however designated.

proceeding against any other security, shall not be required to proceed against

or all of the indebtedness secured hereby in any order or at the same time.

     6.3.2. The Mortgagor agrees, to the full extent that it may lawfully do so,
that in any foreclosure or other action brought by the Mortgagee to enforce this
Mortgage, it will not at any time insist upon or plead or in any way take
advantage of any appraisement, valuation, stay, marshalling of assets,
extension, redemption or moratorium law now or hereafter in force and effect so
as to prevent, hinder, delay or otherwise affect the enforcement of the
provisions of this Mortgage or any rights or remedies the Mortgagee may have
hereunder or by law.

     6.3.3. If the Mortgagee shall elect to accelerate the indebtedness secured
hereby following the occurrence of an Event of Default, the Mortgagor, within
five (5) days after demand, will pay to the Mortgagee, or any receiver appointed
in connection with the foreclosure of this Mortgage, any and all amounts then
held as security deposits under all Space Leases; and the Mortgagee or such

     6.4.1. The Mortgagor will pay to the Mortgagee, on demand, all costs,

title, rights and lien created by this Mortgage (including, without limitation,
reasonable attorneys' fees) shall be paid by the Mortgagor, together with
interest thereon at the Involuntary Rate from the date of the Mortgagee's demand
for such payment to the date of reimbursement by the Mortgagor.

     6.5. Remedies Cumulative; No Waiver; Etc.

     6.5.1. No remedy in this Mortgage conferred upon or reserved to the
Mortgagee is intended to be exclusive of any other remedy or remedies, and each
and every such remedy shall be cumulative, and shall be in addition to every
other remedy given hereunder or now or hereafter existing at law or in equity.
No delay or omission by the Mortgagee in exercising any right or power arising
upon any Event of Default shall impair any such right or power, or shall be
construed to be a waiver of or acquiescence in any such Event of Default; and
every power and remedy given by this Mortgage to the Mortgagee may be exercised
from time to time as often as the Mortgagee may determine it is appropriate to
do so.

     6.5.2. A waiver in one or more instances of compliance with any of the
terms, covenants, conditions or provisions of the Note, the Loan Agreement or of
the Security Documents shall apply to the particular instance or instances and
at the particular time or times only, and no such waiver shall be deemed a
continuing waiver. In any event, no waiver shall be effective, or be asserted by
the Mortgagor as having been made, unless set forth in a writing signed by the
Mortgagee.

exemption rights with respect to the Mortgaged Premises provided for by the
Constitution and laws of the United States and of the State as against the
collection of the Security Documents, or any part thereof.

     6.6. No Merger. It is the intention of the parties to this Mortgage that if
the Mortgagee shall at any time hereafter acquire title to all or any portion of
the Mortgaged Premises, then, and until the indebtedness secured hereby has been
paid in full, the interest of the Mortgagee hereunder and the lien of this
Mortgage shall not merge or become merged in or with the estate and interest of
the Mortgagee, as the holder and owner of title to all or any portion of the
Mortgaged Premises and that, until such payment, the estate of the Mortgagee in
the Mortgaged Premises and the lien of this Mortgage and the interest of the
Mortgagee hereunder shall continue in full force and

any portion of the Mortgaged Premises.

the Mortgagee need sign any satisfaction of this Mortgage. ANY AGREEMENT

any other term, covenant, condition or obligation required to be performed or
observed by the Mortgagor under this Mortgage or the other Security Documents,
without limiting any other provision of this Mortgage, and without waiving or
releasing the Mortgagor from any obligation or default hereunder, after giving
any notice to the Mortgagor required hereunder and after the passage of any
applicable cure periods (or without such notice in the event of an emergency),
the Mortgagee (or any receiver of the Mortgaged Premises) shall have the right,
but not the obligation, to make any such payment, or to perform any other act or
take any appropriate action, including, without limitation, entry on the
Mortgaged Premises and performance of work thereat, as it, in its sole
discretion, may deem necessary to cause such other term, covenant, condition or
obligation to be promptly performed or observed on behalf of the Mortgagor or to
protect the security of this Mortgage. All amounts advanced by, or on behalf of,
the Mortgagee in exercising its rights under this SECTION 7.3 (including, but
not limited to, legal expenses and disbursements incurred in

connection therewith), together with interest thereon at the Involuntary Rate
from the date of the Mortgagee's demand upon the Mortgagor for reimbursement of
such sums until reimbursement by the Mortgagor, shall be payable by the
Mortgagor to the Mortgagee upon demand and shall be secured by this Mortgage.

     7.4. Additional Sums Payable by the Mortgagor. All sums which, by the terms
of this Mortgage or any of the other Security Documents (excluding however the
principal indebtedness evidenced by the Note), are payable by the Mortgagor to
the Mortgagee shall, together with the interest thereon provided for herein or
in the Note or such other Security Documents, be added to and deemed part of the
indebtedness secured by the lien of this Mortgage whether or not the provision
which obligates the Mortgagor to make any such payment to the Mortgagee
specifically so states.

     7.5. Captions. The captions used in this Mortgage are inserted only as a
matter of convenience and for reference, and in no way define, limit, enlarge or
describe the scope or intent of this Mortgage or in any other way affect this
Mortgage or the construction of any provision hereof.

     7.6. Successors and Assigns. The covenants and agreements contained in this
Mortgage shall run with the land and bind the Mortgagor, the successors and
assigns of the Mortgagor and all subsequent owners, encumbrances and Space
Tenants of the Mortgaged Premises, or any part thereof; and shall inure to the
benefit of the Mortgagee, its successors and assigns and all subsequent
beneficial owners of this Mortgage.

     7.7. Gender and Number. Wherever the context of this Mortgage so requires,
the neuter gender includes the masculine and/or feminine gender and the singular
number includes the plural.

     7.8. Severability. If any one or more of the provisions contained in this
Mortgage shall for any reason be held to be invalid, illegal, or unenforceable
in any respect, such invalidity, illegality or unenforceability shall not affect
any other provisions of this Mortgage; and this Mortgage shall, in such event,
be construed as if such invalid, illegal or unenforceable provision had never
been included.

     7.9. Usury. Anything in the Note, the Loan Agreement, this Mortgage or the
other Security Documents to

the contrary notwithstanding, the Mortgagee shall never be entitled to receive,
collect or apply as interest on the principal amount of the Note or any other of
the obligations secured hereby any amount in excess of the maximum rate of
interest permitted to be charged by applicable law. In the event the Mortgagee
ever receives, collects or applies as interest any such excess, the amount which
would be excessive interest shall be applied to the reduction of the principal
amount of said obligations; and if said principal amount shall have been paid in
full, shall be remitted to the Person lawfully entitled thereto. In determining
whether or not the interest paid or payable in any specific instance shall
exceed the highest lawful rate, the Mortgagor and the Mortgagee shall to the
maximum extent permitted by applicable law (i) characterize any non-principal
payment as an expense, fee or premium rather than as interest, (ii) exclude
voluntary prepayments and the effects thereof and (iii) "spread" the total
amount of interest throughout the entire contemplated terms of the obligations
so that the interest rate is uniform throughout the entire said term.

     7.10. Controlling Law. This Mortgage shall be governed by, and construed
and enforced in accordance with the laws of the State of Oklahoma applicable to
contracts made and to be wholly performed within such state.

     7.11. Entire Agreement. This Mortgage, together with the Note, the Loan
Agreement and the other Security Documents, embodies the entire agreement and
understanding between the parties relating to the subject matter hereof.

     2.2. Warranty of Title. The Trustor warrants that, to the best of the
Trustor's knowledge (a) the Mortgaged Premises are free and clear of all liens
and encumbrances other than the Permitted Encumbrances; (b) it owns the Building
Service Equipment and Furnishings free and clear of all liens and claims other
than in favor of the Beneficiary; (c) this Trust Deed is and will remain a valid
and enforceable first lien deed of trust on the Mortgaged Premises, subject only
to the Permitted Encumbrances; and (d) the Trustor has the right and lawful
authority to mortgage and convey the Mortgaged Premises in the manner and form
herein provided. The Trustor represents and warrants to the Beneficiary, to the
best of the Trustor's knowledge, and covenants for the benefit of the
Beneficiary, as follows:

          (i) that the Trustor is lawfully seized and possessed of a fee in the
     Premises and that the Trustor holds good legal and marketable title thereto
     and to the rest of the Mortgaged Premises, subject only to the Permitted
     Encumbrances; and

          (ii) that the Mortgaged Premises are now free and clear of all liens
     and encumbrances whatsoever, other than the Permitted Encumbrances, that
     the Trustor has good right and lawful authority to mortgage and convey the
     same in the manner and form herein provided and that the Trustor will
     warrant and defend title to the Mortgaged Premises against all claims and
     demands whatsoever.

     2.3. To Maintain Priority of Lien.

     2.3.1. This Trust Deed is and will be maintained as a valid first lien deed
of trust on the Mortgaged Premises, and the Trustor will not, directly or
indirectly, create or suffer or permit to be created, or to stand against the
Mortgaged Premises or any portion thereof, or against the rents, issues and
profits therefrom, and will promptly discharge, any lien or charge prior to or
upon a parity with or junior to the lien of this Trust Deed other than the
Permitted Encumbrances; provided, however, that the Trustor shall not be
required to pay any Imposition prior to the time it shall become due and payable
subject to the provisions of SECTION 2.4.1 hereof, and nothing herein contained
shall prevent the Trustor from contesting the validity of any such Imposition in
accordance with the provisions of SECTION 2.4.4. The Trustor will keep and
maintain the Mortgaged Premises, and every part thereof, free from all liens or
lien notices, of Persons supplying

labor and/or materials in connection with any construction, alteration, repair,
improvement or replacement of the Improvements or of the Building Service
Equipment and Furnishings. If any such lien shall be filed against the Mortgaged
Premises, or any part thereof, the Trustor promptly shall discharge the lien of
record, by bonding or otherwise. The Trustor shall exhibit to the Beneficiary,
upon request, appropriate receipts or other satisfactory evidence of the payment
of the Impositions or any other item which may, if not paid, give rise to a lien
against the Mortgaged Premises.

     2.4. To Pay Impositions.

     2.4.1. The Trustor will pay or cause to be paid, as and when due and
payable, all Impositions levied upon the Mortgaged Premises or any part thereof.
However, if by law, any Imposition may at the option of the taxpayer be paid in
installments (whether or not interest shall accrue on the unpaid balance
thereof), the Trustor shall have the right to exercise such option and to pay
such Imposition, or cause it to be paid (together with any accrued interest on
the unpaid balance) in installments as they fall due and before any fine,
penalty, further interest or cost may be added thereto.

     2.4.2. If an Event of Default shall occur and be continuing, then upon
demand of the Beneficiary, the Trustor shall deposit with the Beneficiary a sum
which bears the same relation to the annual insurance premiums for all insurance
required by the terms hereof and real estate taxes and assessments assessed
against the Mortgaged Premises for the insurance period or tax year then in
effect, as the case may be, as the number of months elapsed as of the date of
such demand since the last preceding installment of said premiums or taxes or
assessments shall have become due and payable bears to twelve (12). For the
purpose of this computation, the month in which such last preceding installment
of premiums or real estate taxes or assessments became due and payable and the
month in which such demand is given shall be included and deemed to have
elapsed. On the first day of the month next succeeding the month in which such
demand is given, and thereafter on the first day of each and every month during
the term of this Trust Deed, the Trustor shall deposit with the Beneficiary a
sum equal to one-twelfth of such insurance premiums and such taxes and
assessments for the then-current insurance period and tax year, so that as each
installment of such premiums and taxes and assessments shall become due and
payable, the Trustor shall have deposited with the Beneficiary a sum sufficient

                                     - 10 -

to pay the same. All such deposits shall be received and held as part of such
deposit by the Beneficiary (all such deposits to be held in an account without
interest thereon) and shall be applied to the payment of each installment of
such premiums and taxes and assessments as they shall become due and payable.
The Beneficiary shall, upon demand, furnish evidence to the Trustor of the
making of each such payment. If the amount of such premiums and taxes and
assessments has not been definitely ascertained at the time when any such
monthly deposits are required to be made, the Trustor shall make such deposits
based upon the amount of such premiums and taxes and assessments for the
preceding year, subject to adjustment as and when the amount of such premiums
and taxes and assessments are ascertained. If at any time when any installment
of such premiums and such taxes and assessments becomes due and payable the
Trustor shall not have deposited a sum sufficient to pay the same, the Trustor
shall, within five (5) days after demand, deposit any deficiency with the
Beneficiary. Upon payment in full of the indebtedness secured by this Trust
Deed, any remaining amount on deposit with the Beneficiary shall be repaid to
the Person lawfully entitled thereto. If an Event of Default shall occur and be
continuing, the Beneficiary may, at its option, apply all or any portion of the
amounts then on deposit with the Beneficiary pursuant to this SECTION 2.4.2
first to the payment of any premiums, taxes or assessments then due, and any
remaining amounts may be applied to the payment of the indebtedness. The Trustor
shall deliver to the Beneficiary all insurance and tax bills promptly following
receipt during any period when such monthly deposits are to be made with the
Beneficiary.

     2.4.3. The Trustor will pay all taxes and other governmental charges
(including, without limitation, stamp taxes), except income or franchise taxes
or similar taxes based upon or measured by income, assessed by the United States
government or any state or local governmental authority and imposed on the
Beneficiary, its successors by reason of the ownership of this Trust Deed or the
Note or the receipt of the interest or other sums payable thereunder or payable
by either the Trustor or the Beneficiary upon any increase in the indebtedness
secured hereby, or any modification, amendment, extension or consolidation of
this Trust Deed. Without limiting the foregoing and subject to the limitations
set forth above, the Trustor will also pay the whole of any tax imposed,
directly or indirectly, on this Trust Deed or the Note or the receipt of any
portion of the Indebtedness in lieu of a tax on the Mortgaged Premises or the
Improvements and Building Service Equipment, whether by reason of (a) the
passage after the date of this Trust

Deed of any law of the State deducting from the value of real property for the
purposes of taxation any lien thereon; (b) any change in the laws for the
taxation of Trust Deeds or debts secured by trust deeds for state or local
purposes; (c) a change in the means of collection of any such tax or otherwise;
or (d) any tax, whether or not now existing, assessed against, or withheld from,
interest or other payments made by the Trustor or assessed against this Trust
Deed and which are assessed or levied by the government of any foreign nation or
political subdivision thereof, provided such tax liability shall not result from
the ownership of this Trust Deed by a Person not a citizen of, or an entity not
formed under the laws of, the United States or any state. Within a reasonable
time after payment of any such tax or governmental charge, the Trustor will
deliver to the Beneficiary satisfactory proof of payment thereof, subject,
however, to the right of the Trustor to contest Impositions as hereinafter set
forth. If the Trustor shall fail to pay such tax or charge within fifteen (15)
days after written notice, or if under applicable law the Trustor's payment or
agreement to pay the same shall be unenforceable, the Beneficiary shall have the
right to declare the entire unpaid indebtedness and all accrued and unpaid
interest thereon due and payable on a date specified by the Beneficiary, but, in
any event, not less than thirty (30) days after written notice to the Trustor.

     2.4.4. The Trustor shall have the right to contest the amount or validity,
in whole or in part, of any Imposition, or to seek a reduction in the valuation
of the Mortgaged Premises, or any part thereof, as assessed for real estate or
personal property tax purposes by appropriate proceedings diligently conducted
in good faith, but only after payment of such Imposition, unless such payment
would operate as a bar to such contest or materially adversely interfere with
the prosecution thereof, in which event the Trustor may postpone or defer
payment of such Imposition (but not the payment of any monthly deposits pursuant
to SECTION 2.4.2 hereof); and upon request by the Trustor, the Beneficiary shall
postpone or defer payment of such Imposition; provided, however, that if at any
time the Mortgaged Premises, the Building Service Equipment, the Furnishings, or
any part thereof would, in the Beneficiary's reasonable judgment, by reason of
such postponement or deferment be in imminent danger of being forfeited or lost,
or if the Beneficiary might be subjected to any civil or criminal liability or
other sanction, then the Trustor, on demand, shall immediately pay or cause to
be paid the amount so contested and unpaid, together with all interest and
penalties in connection therewith.

     2.4.5. The certificate, advice or bill of the appropriate official
designated by law to make or issue the same or to receive payment of any
Imposition indicating the nonpayment of such Imposition shall be prima facie
evidence that such Imposition is due and payable but unpaid at the time of the
making or issuance thereof.

     2.5. Insurance; Restoration Following Casualty.

     2.5.1. Until the indebtedness secured hereby is paid in full, the Trustor
shall at its own expense at all times maintain or cause to be maintained on all
of the Mortgaged Premises (a) comprehensive general liability insurance,
including umbrella liability insurance, covering all claims for bodily injury,
including death, and property damage occurring on, in or about the Mortgaged
Premises in an aggregate amount of not less than Five Million Dollars
($5,000,000) per occurrence, and a single limit of not less than Two Million
Dollars ($2,000,000) per person and per occurrence for personal injury, bodily
injury and property damage; the policy shall have no deductible or self insured
retention requirements; the policy limits of such insurance, if requested by the
Beneficiary, shall be increased from time to time to reflect what a reasonably
prudent owner or lessee of buildings or improvements similar in type and
locality to the Mortgaged Premises would carry; during any period of substantial
alterations or improvements in, on or to the Mortgaged Premises, the Trustor
will cause the comprehensive general liability insurance, including umbrella
liability insurance, endorsed to provide owners' and contractors' protective
liability coverage, including completed operations liability coverage; (b)
physical damage insurance (all risk non-reporting property insurance, including
earthquake insurance, with the Beneficiary named as loss payee), covering the
Mortgaged Premises for loss or damages resulting from the perils of fire,
lightning, earthquake, and such other risks and hazards as are provided under
the current standard "Extended Coverage Endorsement" and vandalism and malicious
mischief coverage, for the full replacement value of the Mortgaged Premises on a
stipulated and agreed-amount basis; (c) if the Mortgaged Premises is in an area
identified as a flood hazard area by the Secretary of Housing and Urban
Development, flood insurance, to the extent obtainable, in an amount equal to
the lesser of the full replacement value of the Mortgaged Premises or the
maximum amount available under the Federal flood insurance program; (d) boiler
and machinery insurance covering all boilers, machinery, air conditioning,
pressure vessels, and similar type equipment commonly covered under a broad-form
boiler and machinery policy, in an amount satisfactory to

                                     - 13 -

the Beneficiary; (e) insurance against such other risks of damage, hazards,
casualties and contingencies in such amounts as the Beneficiary shall from time
to time reasonably require, provided that insurance against such other risks,
hazards, casualties or contingencies shall then be commonly carried by prudent
owners or lessees of building or improvements in the locality similar in
character, construction, use and occupancy to the Improvements, Building Service
Equipment and Furnishings on, or constituting a part of, the Mortgaged Premises;
and (f) loss of rents/business interruption coverage in an amount sufficient to
pay all Impositions, insurance premiums, interest and principal installments and
all other amounts due under the Note and the Loan Agreement and the normal
operating expenses of the Mortgaged Premises, all for a period of one (1) year.
Furthermore, the Beneficiary reserves the right to require additional insurance
and/or higher policy limits than heretofore specified if such additional
insurance and/or higher policy limits are commercially reasonable for similar
properties, which right may be exercised by written notice to the Trustor, and,
as soon thereafter as practicable, but in any event within thirty (30) days of
the receipt thereof, the Trustor agrees to obtain insurance coverage complying
with such notice. The proceeds of all such insurance (except the insurance
specified in SECTION 2.5.1(a)) shall be paid solely to the Beneficiary and be
held, applied or disbursed by the Beneficiary as provided in SECTIONS 2.5.7 and
2.5.8.

     2.5.2. All insurance required in SECTION 2.5.1 shall be evidenced by valid
and enforceable policies, in form and substance as shall be required by the
Beneficiary from time to time, and issued by and distributed among insurers of
recognized responsibility having an A.M. Best's Guide of A:XII or better, a
financial size category of Class XI or above, and the total limit of liability
shall not exceed ten percent (10%) of the total policyholders' surplus. Such
insurers shall be authorized to do business in the State and in all other
respects shall be reasonably satisfactory to the Beneficiary. The originals of
all such policies, or duplicate copies or certificates thereof, shall be
delivered to the Beneficiary concurrently with the execution and delivery of
this Trust Deed. Thereafter, all renewal or replacement policies, or duplicate
copies or certificates thereof, shall be delivered to the Beneficiary not less
than fifteen (15) days prior to the expiration date of the policy or policies to
be renewed or replaced, in each case accompanied by evidence reasonably
satisfactory to the Beneficiary that all premiums currently payable with respect

                                     - 14 -

to such policies have been paid in full by or at the direction of the Trustor.

     2.5.3. All such insurance policies shall (a) except for any liability
policy required hereunder, contain a standard noncontributory form of mortgagee
clause (in favor of and entitling the Beneficiary to collect any and all
proceeds payable under such insurance), as well as a standard waiver of
subrogation endorsement, all to be in form and substance reasonably satisfactory
to the Beneficiary; (b) provide that such policies may not be cancelled or
amended without at least thirty (30) days prior written notice to the
Beneficiary; and (c) provide that no act, omission or negligence of the Trustor,
or its agents, servants or employees, or of any Space Tenant under any Space
Lease, which might otherwise result in a forfeiture of such insurance or any
part thereof, shall in any way affect the validity or enforceability of such
insurance insofar as the Beneficiary is concerned. The Trustor shall not carry
separate insurance, concurrent in kind or form or contributing in the event of
loss with any insurance required under this SECTION 2.5. All losses under such
insurance policies shall be adjusted by the Trustor in the case of any single
instance of such damage or destruction not exceeding $200,000, by the Trustor
and the Beneficiary in the case of any such single instance of damage or
destruction exceeding such amount, provided that in no event shall the Trustor
approve or consent to any final adjustment in any amount exceeding the amount
specified above in this sentence without obtaining the Beneficiary's prior
approval (which approval shall not be unreasonably withheld) of the amount of
such adjustment, and solely by the Beneficiary in the case when an Event of
Default exists and is continuing.

     2.5.4. The Trustor, at its expense, will furnish to the Beneficiary, within
ninety (90) days after written demand, but in no event, except for reasonable
cause, more frequently than annually, proof of the then full replacement value
of each of the Improvements and the Building Service Equipment and Furnishings
therein, such proof to be by appraisals reasonably satisfactory in form and
substance to the Beneficiary and prepared by an appraiser (who may be an
appraiser for the insurance company insuring such property) designated and paid
for by the Trustor and approved by the Beneficiary, which approval shall not be
unreasonably withheld or delayed.

     2.5.5. If the Beneficiary shall, by any means, acquire the title or estate
of the Trustor in or to any portion of the Mortgaged Premises, it shall
thereupon

                                     - 15 -

become the sole and absolute owner of all insurance policies affecting such
portion of the Mortgaged Premises held by, or required hereunder to be delivered
to, the Beneficiary, with the sole right to collect and retain all unearned
premiums thereon; and the Trustor shall be entitled only to a credit in
reduction of the then outstanding indebtedness secured hereby in the amount of
the short rate cancellation refund, when and if received by Beneficiary. The
Trustor agrees, immediately upon demand, to execute and deliver such assignments
or other authorizations or instruments as may, in the reasonable opinion of the
Beneficiary, be reasonably necessary or desirable to effectuate any of the
provisions of this SECTION 2.5.5.

     2.5.6. If any of the Improvements, Building Service Equipment or
Furnishings shall be damaged or destroyed, in whole or in part, by fire or other
casualty, the Trustor shall give prompt notice thereof to the Beneficiary, and,
without regard to the availability or adequacy of insurance proceeds, shall
promptly following receipt of any insurance proceeds or the date when any such
proceeds are made available to the Trustor in accordance with the terms hereof,
commence to restore, replace, rebuild or alter the same as nearly as possible to
the condition, character and value thereof existing immediately prior to such
damage or destruction. Any insurance proceeds in respect of such damage or
destruction, or any Award (as defined in SECTION 3.2) for a partial taking which
is not a substantial or total taking, as such terms are referred to in ARTICLE
III hereof, at the option of the Beneficiary, may either (i) be applied as a
prepayment of the unpaid balance of the principal of the Note and of accrued and
unpaid interest thereon and as a payment of any other sums due and owing under
the Note, the Loan Agreement and the Security Documents, or (ii) be made
available to pay or reimburse costs incurred for restoration, replacement or
rebuilding necessitated as a result of such damage or destruction, or as a
result of such taking, as the case may be, or (iii) be used for any other
purpose or object deemed appropriate by the Beneficiary in connection with the
Mortgaged Premises, provided, however, that the Beneficiary may not elect either
option (i) or (iii) above if, and for so long as all of the following conditions
(collectively, the "Insurance or Award Conditions" have been and remain
satisfied: (a) no Event of Default has occurred and is continuing or would occur
as a result of such casualty or taking and no event has occurred that with the
passage of time or the giving of notice, or both, would constitute an Event of
Default; (b) the balance of the insurance proceeds or such Award either
initially paid to the Beneficiary or deposited with the Depository (as

                                     - 16 -

hereinafter defined) or remaining from time to time, shall be sufficient, in the
Beneficiary's reasonable judgment, to complete the restoration, replacement or
rebuilding, or the Trustor shall have deposited such sufficient funds with the
Beneficiary or the Depository; and (c) the Beneficiary determines, in its
reasonable discretion, that (i) the Loan to Value Ratio (as defined in the Loan
Agreement, and taking into consideration the value of all of the Projects, as
defined in the Loan Agreement) is not greater than 55%, and (ii) the Debt
Service Coverage Ratio (as defined in the Loan Agreement, and taking into
consideration the loss of income resulting from such damage or destruction as
projected by the Beneficiary in its reasonable discretion) is not less than
1.40:1.0. Notwithstanding the foregoing, if an event has occurred and is
continuing that with the passage of time or the giving of notice, or both, would
constitute an Event of Default but the same has not yet matured into an Event of
Default, then, if the conditions set forth in the foregoing clauses (b) and (c)
have been or will be, in the Beneficiary's reasonable judgment, satisfied, the
Beneficiary shall not elect either option (i) or (iii) unless such event shall
have matured into an Event of Default and, unless and until such event shall
have so matured into an Event of Default or such event has been cured or shall
otherwise cease to exist, the Beneficiary (or the Depository) shall not release
any such insurance proceeds or Award and the same shall be held until an Event
of Default occurs or the Default has been cured or shall otherwise cease to
exist.

     2.5.7. Any such insurance proceeds (other than the proceeds of the rent
insurance policy, which shall be paid as provided in SECTION 2.5.8 below) or
Award which are to be applied to restoration, replacement or rebuilding of the
Mortgaged Premises shall, after payment or reimbursement to the Beneficiary of
all reasonable costs and expenses of the Beneficiary in collecting such proceeds
or Award, be applied upon satisfaction of the following provisions and
conditions:

          (a) If the damage be of such nature as to require the Trustor to
     construct a replacement for, or to alter in any material or substantial
     way, the damaged or destroyed items, the Trustor shall, before commencing
     any such work, submit copies of the plans and specifications therefor to
     the Beneficiary for the Beneficiary's approval, such approval to not be
     unreasonably withheld or delayed.

<PAGE>



          (b) If after payment or reimbursement to the Beneficiary of all costs
     and expenses of the Beneficiary in collecting such insurance proceeds or
     Award, the aggregate insurance proceeds or Award received by reason of any
     single instance of such damage or destruction or condemnation, as the case
     may be, shall be $200,000 or less such insurance proceeds or Award shall be
     paid to the Trustor, which shall hold all amounts so received in trust for
     application first to pay the entire cost of restoring, repairing,
     rebuilding or replacing the damaged or destroyed items, before any portion
     of such proceeds may be used or applied for any other purpose. If the
     aggregate net insurance proceeds or Award by reason of any single instance
     of such damage or destruction or condemnation, as the case may be, shall be
     more than $200,000 such sums shall be held and disbursed by Fleet Bank,
     National Association or, if this Trust Deed is held by another financial
     institution, by such financial institution or, if this Trust Deed is not
     held by a financial institution, by a financial institution selected by the
     then Beneficiary (the holder of such monies, the "Depository") in
     accordance with the following provisions of this SECTION 2.5.7.

          (c) The Beneficiary shall have received as to each such disbursement a
     certificate of the Trustor (i) requesting the payment of a specified amount
     of such insurance or condemnation proceeds; (ii) describing in reasonable
     detail the work and materials applied to the restoration, replacement or
     rebuilding of the damaged, destroyed or taken Improvement, or Building
     Service Equipment and/or Furnishings located therein, since the date of the
     last such certificate; (iii) stating that the requested amount does not
     exceed the cost of such work and materials; and (iv) stating that a request
     for payment for such work and materials has not previously been made,
     accompanied by:

               1. a certificate of an independent engineer or architect
          designated by the Trustor, who shall have been approved in writing by
          the Beneficiary (such approval not to be unreasonably withheld),
          stating (i) that the work and materials described in the accompanying
          certificate of the Trustor were satisfactorily performed and furnished
          and were necessary, appropriate or desirable to the restoration,
          replacement or rebuilding

          of the damaged, destroyed or taken Improvement, or Building Service
          Equipment and/or Furnishings; (ii) that the amount specified in such
          certificate of the Trustor does not exceed the reasonable cost of such
          work and materials; and (iii) the additional amount, if any, required
          to complete the restoration, replacement or rebuilding of the damaged,
          destroyed or taken Improvement, Building Service Equipment and/or
          Furnishings; and

               2. evidence reasonably satisfactory to the Beneficiary (i) that
          there exists no filed or recorded lien, or lien notice, or encumbrance
          or charge in respect of all or any part of the Mortgaged Premises that
          is prior to or on a parity with the lien of this Trust Deed, except as
          may be permitted in the Permitted Encumbrances; (ii) that neither the
          Mortgaged Premises nor any part thereof is subject to any recorded or
          filed mechanic's, laborer's, materialman's or any similar lien,
          encumbrance or charge; and (iii) that none of the Building Service
          Equipment and Furnishings provided in connection with such
          restoration, replacement or rebuilding is subject to any security
          interest other than in favor of the Beneficiary;

     Upon satisfaction of the conditions set forth herein, the Beneficiary shall
pay to the Trustor the amount of such insurance or condemnation proceeds
requested in such certificate of the Trustor or consent to the Depository's
payment thereof, as the case may be; provided, however, that in no event shall
the balance of insurance or condemnation proceeds held by the Beneficiary and
the Depository be reduced below the amount specified in such certificate of the
independent engineer or architect as the amount required to complete the
restoration, replacement or rebuilding of the damaged, destroyed or taken
Improvement, Building Service Equipment and/or Furnishings. Each such payment,
whether made by the Beneficiary or the Depository, shall be held by the Trustor
in trust and shall be used solely for the payment of the cost of the work and
materials described in the certificate of the Trustor, or if such cost or any
part thereof has theretofore been paid by the Trustor out of its own funds, then
for the reimbursement to the Trustor of any such cost or part thereof paid by
it. Any balance of insurance or condemnation proceeds held by the Beneficiary
after the completion of the restoration, replacement or

rebuilding and payment of all costs incurred in connection therewith, to be
evidenced by a certificate to such effect of such independent engineer or
architect delivered to the Beneficiary, shall, if no Event of Default shall have
occurred and be continuing, be released to the Person lawfully entitled thereto.
Notwithstanding the foregoing, if the Trustor needs to make deposits with or
payments to contractors prior to the work being performed, if the Beneficiary is
otherwise obligated to allow funds to be used to rebuild or restore, the
Beneficiary agrees that it will not unreasonably withhold or delay its consent
to the Trustor's request that such deposits or advances payments be allowed.

     2.5.8. All proceeds of rent insurance payable as a result of the occurrence
of any fire or other casualty which affects the Mortgaged Premises, or any part
thereof, shall be paid to the Beneficiary or, if the Beneficiary is not a
financial institution, the Depository. The Beneficiary or the Depository, as the
case may be, if it shall receive such proceeds, shall hold such proceeds in
trust if permitted under law, and in an account bearing interest (payable to or
for account of the Trustor), and shall apply or cause such proceeds (including
any net interest thereon) to be applied to the payment of those items referred
to in SECTION 2.5.1(f) which become, and as they become, due and payable from
and after the date of the occurrence of such damage or loss, until the
completion of the necessary restoration or replacement by the Trustor or until
the exhaustion of such proceeds (including any interest thereon), whichever
first occurs. Upon completion of such restoration or replacement, any balance of
such rent insurance proceeds, together with the interest thereon, if any, not
theretofore applied as provided herein, in the hands of the Beneficiary or the
Depository, as the case may be, shall, provided that no Event of Default shall
have occurred and be continuing, be paid to the Person lawfully entitled
thereto.

     2.5.9. Nothing in this SECTION 2.5 contained shall (i) relieve the Trustor
of its duty to repair, restore, rebuild or replace the Improvements, Building
Service Equipment and/or Furnishings following damage or destruction by fire or
other casualty or taking in the event that no Award or an inadequate Award or
that no or inadequate proceeds of insurance are available to defray the cost of
such repairing, restoring, rebuilding or replacement (provided, however, the
Trustor shall be permitted to receive the insurance proceeds upon satisfaction
of the conditions set forth herein provided, in addition, that all


                                     - 20 -

of the Insurance or Award Conditions have been and remain satisfied), or (ii)
relieve the Trustor of its obligation to pay principal and interest and to make
all other payments required by the Note, the Loan Agreement and this Trust Deed
subsequent to the occurrence of any fire or other casualty, or taking, except
if, and to the extent that, any proceeds of rent insurance are applied by the
Beneficiary in accordance with SECTION 2.5.8 to such required payments.

     2.5.10. If, while any insurance proceeds or Award is being held by the
Beneficiary or the Depository, an Event of Default shall occur and be
continuing, the Beneficiary shall be entitled to receive and apply all such
insurance proceeds or Award in reduction of the indebtedness and other
obligations secured by this Trust Deed, in such order and respective amounts, as
the Beneficiary in its discretion shall determine.

     2.6. To Comply with Laws.

     2.6.1. The Trustor, at its own expense, will promptly cure all violations
of law affecting the Mortgaged Premises, or any part thereof, and/or the use and
operation thereof and will promptly comply, or cause to be complied with, all
present and future Legal Requirements. However, the Trustor shall have the
right, after prior notice to the Beneficiary, to contest by appropriate legal
proceedings, diligently conducted in good faith, the validity or application of
any Legal Requirement if and so long as the Trustor shall promptly furnish to
the Beneficiary a certificate to such effect showing the steps taken to comply
with such provisions, provided that:

          (a) if by the terms of any such Legal Requirement, compliance
     therewith pending the prosecution of any such proceeding may be delayed
     legally without incurring any lien, charge or liability of any kind against
     the Mortgaged Premises, or any part thereof, and without subjecting the
     Trustor or the Beneficiary to any liability, civil or criminal, for failure
     so to comply therewith, the Trustor may delay compliance therewith until
     the final determination of any such proceeding; and

          (b) if any lien, charge or civil liability would be incurred by reason
     of any such delay, the Trustor nevertheless, on the prior written consent
     of the Beneficiary, such consent not to be unreasonably withheld, may
     contest and delay compliance with the Legal Requirement, provided that such
     delay


                                     - 21 -

     would not subject the Beneficiary to criminal liability and the Trustor (i)
     furnishes to the Beneficiary security reasonably satisfactory to the
     Beneficiary against loss or injury by reason of such contest or delay and
     (ii) prosecutes the contest with due diligence.

     2.6.2. Notwithstanding the provisions of SECTION 2.6.1, if any delay in
compliance with any Legal Requirement shall, in the reasonable judgment of the
Beneficiary, place all or any part of the Mortgaged Premises in imminent danger
of being forfeited or lost, the Trustor shall, upon written notice from the
Beneficiary, immediately comply with such Legal Requirement.

     2.6.3. The Trustor will use and permit the use of the Mortgaged Premises
only in accordance with the material requirements of any applicable licenses and
permits issued by Governmental Authorities.

     2.6.4. The Trustor will procure, pay for and maintain (or cause to be
procured, paid and maintained) all permits, licenses and other authorizations
required to be procured and maintained by the owners and operators of the
Mortgaged Premises for any then use of all or any part of the Mortgaged Premises
then being made and for the lawful and proper operation and maintenance thereof.

     2.7. Limitation on Alterations and Demolition.

     2.7.1. The Trustor shall not voluntarily demolish, replace or alter the
Mortgaged Premises, or any part thereof, or voluntarily make any addition
thereto, or voluntarily construct any additional improvements thereon, or suffer
any of the same to occur, whether structural or otherwise (collectively,
"change"), without the prior written consent of the Beneficiary, which consent
shall not be unreasonably withheld or delayed; provided, however, that if no
Event of Default is continuing and such change involves an estimated cost of
less than $100,000 and is non-structural or if no Event of Default is continuing
and such change is non-structural and is being made to prepare space for a Space
Tenant pursuant to a Space Lease entered into in accordance with the Loan
Agreement, then, in either of such events, the Beneficiary's consent shall not
be required; provided, further, however, that if any such change is required by
law, the Trustor may make such change with the prior written consent of the
Beneficiary, which consent the Beneficiary will not unreasonably withhold or
delay. As a condition to any consent under this SECTION 2.7.1, the


                                     - 22 -

Beneficiary may require (a) that plans and specifications for the proposed work,
prepared by a reputable architect reasonably satisfactory to the Beneficiary, be
submitted to the Beneficiary for approval, and (b) that the Trustor obtain a
payment and performance bond or other security reasonably satisfactory to the
Beneficiary in form and amount reasonably satisfactory to the Beneficiary from
the contractor or subcontractor performing the work unless such work amounts to
less than $200,000 in aggregate total cost. All work performed by or on behalf
of the Trustor shall be completed with all reasonable diligence and continuity,
in a good and workmanlike manner, and in compliance with all applicable Legal
Requirements. Unless, and to the extent that, the provisions of SECTION 2.7.2 be
applicable, no Building Service Equipment or Furnishings shall be removed from
the Mortgaged Premises during the course of any such work without prior
notification to the Beneficiary and unless provision is made for return or
replacement on or prior to the completion of the work. The provisions of this
SECTION 2.7.1. shall apply to any change made or required to be made by the
Trustor in the course of complying with any other of the provisions of this
Trust Deed. A duplicate set of all plans and specifications required to be filed
with any Governmental Authority prior to, or at any time in connection with, any
such alteration, demolition or new construction shall be furnished to the
Beneficiary. The Trustor will pay on demand the reasonable expenses incurred by
the Beneficiary in the review of plans and specifications provided for in this
Trust Deed.

     2.7.2. The Trustor shall have the right, at any time and from time to time,
to remove and dispose of any item of Building Service Equipment or Furnishings
which may have become obsolete or unfit for use or which is no longer useful in
the operation of the Improvements, provided that the Trustor promptly replaces
such item with other Building Service Equipment or Furnishings, free of superior
title, liens or claims (other than in favor of the Beneficiary) unless consent
of the Beneficiary is first obtained, not necessarily of the same character but
of at least equal quality, value and usefulness in connection with the operation
and maintenance of the Mortgaged Premises, provided, further, however, no
removal of any item of Building Service Equipment or Furnishings then having a
fair market value of $50,000 or more shall be made without the prior written
consent of the Beneficiary, which consent will not be unreasonably withheld or
delayed. However, if by reason of technological or other developments in the
operation and maintenance of buildings and other improvements of the general
character of the Improvements or

                                     - 23 -

01/09/97 KDF:

<PAGE>



a change in the use of the Mortgaged Premises or any part thereof, no
replacement of the Building Service Equipment or Furnishings so removed would be
necessary or desirable for the proper operation or maintenance of the
Improvements, the Trustor shall not be required to replace the item so removed.

     2.8. Limitation on Disposition of the Mortgaged Premises.

     2.8.1. Except as expressly set forth in this Trust Deed or the Loan
Agreement (including, without limitation, Sections 5.01 and 6.21 of the Loan
Agreement), the Trustor shall not directly or indirectly sell, assign, mortgage,
alienate, pledge or otherwise transfer or further encumber the Mortgaged
Premises or any part thereof or any interest therein or in any of the rents,
profits or income generated thereby, whether voluntarily, involuntarily, by
operation of law or otherwise, or lease all or any portion thereof or an
undivided interest therein, without the prior written consent of the
Beneficiary. The foregoing events are hereinafter referred as a "Transfer". Any
transfer without prior written the consent of the Beneficiary is an Event of
Default.

     2.8.2. If there shall be a violation of the terms and provisions of SECTION
2.8.1, whether by the Trustor or any other person, in addition to all other
rights and remedies available to the Beneficiary under this Trust Deed, the
Beneficiary shall have the option, by the giving of notice to the Trustor, of
declaring the entire unpaid principal balance of the Note, together with all
accrued and unpaid interest and all other sums and charges evidenced thereby or
payable pursuant to the Loan Agreement, immediately due and payable.

     2.9. Maintenance of Mortgaged Premises; Covenant Against Waste; Inspection
by the Beneficiary. The Trustor will not commit or permit waste on the Mortgaged
Premises and, at its expense, will keep and maintain the Improvements, the
Building Service Equipment and Furnishings in its (or their) present state of
repair and condition, reasonable wear and tear excepted, and, if improved, in
such improved state of repair and condition, reasonable wear and tear excepted;
provided, that this shall not limit the Trustor's other obligations hereunder,
such as compliance with laws. The Trustor shall do or cause to be done all
maintenance and make or cause to be made all repairs as may be required by the
landlord under any Space Lease. The Trustor will neither do nor permit to be
done anything to the Mortgaged

                                     - 24 -

Premises that may materially impair the value thereof or which may violate any
covenant, condition or restriction affecting the Mortgaged Premises, or any part
thereof, or which would effect any material change therein or in the condition
thereof that would increase the danger of fire or other hazard arising out of
the operation of the Mortgaged Premises. Subject to the rights of Space Tenants,
the Beneficiary, and its representatives and agents, may enter and inspect the
Mortgaged Premises at any time after reasonable notice (which may be oral)
during usual business hours, and the Trustor shall, within thirty (30) days
after demand by the Beneficiary (or immediately upon demand in case of
emergency), make such repairs, replacements, renewals or additions, or perform
such items of maintenance, to the Mortgaged Premises as the Beneficiary may
reasonably require in order to cause the Mortgaged Premises to comply with the
standards established in this SECTION 2.9.

     2.10. To Furnish Certificates; Other Reporting Requirements.

     2.10.1. The Trustor will, at its own expense, deliver to the Beneficiary,
within fifteen (15) days after written request, but no more frequently than once
per six (6) month period, a written statement executed by the Trustor, in
recordable form, setting forth to the best of the Trustor's knowledge, the
amount then unpaid upon the Note and secured by this Trust Deed and stating
whether any offsets or defenses exist against the indebtedness secured hereby;
and, if any such offsets or defenses are alleged to exist, then the factual
basis and amount of such claimed offsets or defenses.

     2.10.2. The Trustor will, if requested by the Beneficiary, deliver to the
Beneficiary a certificate of an officer of the general partner of the Trustor or
of such general partner's general partner, to the effect that he is familiar
with this Trust Deed and the other Security Documents, has reviewed the affairs
of the Trustor, and to the best of his knowledge and belief there exists no
Event of Default and no act or event has occurred or exists which with notice or
lapse of time or both could become such an Event of Default, or if any such
event or Event of Default exists, specifying it and what action the Trustor is
taking to cause it to be remedied.

     2.11. After-Acquired Property. All right, title and interest of the Trustor
in and to all improvements, betterments, renewals, substitutes and replacements
of, and all additions and appurtenances to, the Mortgaged Premises

hereafter acquired, constructed, assembled or placed on the Mortgaged Premises,
immediately upon such acquisition, construction, assembly or placement, as the
case may be, and in each such case without any further mortgage, conveyance or
assignment or other act of the Trustor, shall become subject to the lien of this
Trust Deed as fully and completely, and with the same effect, as though now
owned by the Trustor and specifically described in the granting clauses hereof;
and at any time and from time to time the Trustor, on demand, will execute,
acknowledge and deliver to the Beneficiary any and all such further assurances,
mortgages, conveyances or assignments as the Beneficiary may reasonably require
to further evidence, confirm and perfect the provisions of this SECTION 2.11.

     2.12. Further Assurances. The Trustor shall, at its sole cost and without
expense to the Beneficiary, on demand, do, execute, acknowledge and deliver all
and every such further acts, deeds, conveyances, mortgages, assignments, notices
of assignment, transfers and assurances as the Beneficiary shall from time to
time reasonably require for better assuring, conveying, assigning, transferring
and confirming unto the Beneficiary the property and rights hereby mortgaged or
assigned or intended now or hereafter so to be, or which the Trustor may be or
may hereafter become bound to convey, mortgage or assign to the Beneficiary, or
for carrying out the intention or facilitating the performance of the terms of
this Trust Deed, or for filing, registering or recording this Trust Deed.

     2.13. Recorded Instruments. The Trustor will promptly perform and observe,
or cause to be performed and observed, all of the terms, covenants and
conditions of all instruments of record affecting the Mortgaged Premises (other
than non-consensual encumbrances hereafter affecting the Mortgaged Premises, the
validity or enforceability of which the Trustor is contesting in accordance with
this Trust Deed) where non-compliance therewith affects the security of this
Trust Deed or imposes any duty or obligation upon the Trustor or any Space
Tenant. The Trustor shall do or cause to be done all things reasonably required
to preserve intact and unimpaired and to renew any and all rights-of-way,
easements, grants, appurtenances, privileges, licenses, franchises and other
interests and rights in favor of or constituting any portion of the Mortgaged
Premises. The Trustor will not, without the prior written consent of the
Beneficiary, which consent shall not be unreasonably withheld or delayed,
initiate, join in or consent to any private restrictive covenant or other public
or private restriction as to the use of all or any portion


                                     - 26 -

of the Mortgaged Premises. The Trustor will, however, comply with all lawful
restrictive covenants and zoning ordinances and other public or private
restrictions affecting all or any portion of the Mortgaged Premises.


                                  ARTICLE III.

                                  Condemnation


     3.1. Notice of Taking. The Trustor shall promptly notify the Beneficiary if
the Trustor receives notice of the institution of any proceeding or negotiations
for the taking of the Mortgaged Premises, or any part thereof, whether for
permanent or temporary use and occupancy in condemnation or by the exercise of
the power of eminent domain or by agreement of interested parties in lieu of
such condemnation (all the foregoing called a "taking"); shall keep the
Beneficiary currently advised, in detail, as to the status of such proceedings
or negotiations and will promptly give to the Beneficiary copies of all notices,
pleadings, judgments, determinations and other papers received or delivered by
the Trustor in connection with any such proceedings. The Beneficiary shall have
the right to appear and participate in such proceedings and may be represented
by counsel. The Trustor will not, without the Beneficiary's prior written
consent, which consent shall not be unreasonably withheld or delayed, enter into
any agreement for the taking of the Mortgaged Premises, or any part thereof,
with anyone authorized to acquire the Mortgaged Premises by eminent domain or in
condemnation.

     3.2. Condemnation Award. If the Mortgaged Premises shall be the subject of
a taking the Beneficiary shall be entitled to and shall receive the total of
such portion of all awards made that shall be allowed to the Trustor with
respect to all the right, title and interest of the Trustor in and to the
Mortgaged Premises (the award made in any total, partial or temporary taking is
herein called the "Award"), provided that the obligations of the Trustor to
perform the terms, covenants and conditions of this Trust Deed, if any, affected
by such taking shall continue unimpaired until the actual vesting of title in
such proceeding and the actual receipt by the Beneficiary of the Trustor's share
of the entire Award resulting from such taking.

     3.3. Application of Award. The Beneficiary shall have the option of
treating a total taking or a substantial


                                     - 27 -

taking (as hereinafter defined) as an Event of Default and of accelerating the
entire indebtedness secured hereby, in which event it shall apply the Trustor's
entire Award in reduction of such indebtedness (including principal, interest
and other sums secured hereby, in such order as the Beneficiary may determine)
and shall turn over any balance remaining, if any, to the Person lawfully
entitled thereto; or if the Beneficiary shall not so elect to accelerate the
indebtedness and apply the Award thereto, then the total Award shall, regardless
of amount, be deposited with the Beneficiary or with the Depository, the Trustor
hereby agreeing to elect that such proceeds be held and disbursed by the
Depository in accordance with SECTIONS 2.5.6, 2.5.7, 2.5.8, 2.5.9 and 2.5.10
hereof for restoration required to be made by the Trustor. If there be a partial
taking, the net proceeds of the Award shall be deposited with the Beneficiary
and applied by the Beneficiary in accordance with the provisions of SECTIONS
2.5.6, 2.5.7, 2.5.9 and 2.5.10. Any Award remaining after the completion of such
restoration, replacement or rebuilding shall be applied in reduction of the
indebtedness (including principal, interest and other sums secured hereby) in
such order as the Beneficiary shall determine. A partial taking is substantial
only if it materially decreases the fair market value of the Mortgaged Premises
and the remainder of the Mortgaged Premises cannot be restored to an
economically viable whole.

     3.4. Temporary Taking. If any Award payable to the Trustor on account of a
taking for temporary use or occupancy is made in a lump sum or is payable other
than in equal monthly installments, the Trustor shall pay over such Award to the
Depository and such Award shall be applied to installments of Impositions and of
principal and interest and all other charges secured by this Trust Deed or due
under the Note, the Loan Agreement, or the other Security Documents as and when
the same become due and payable. Any unapplied portion of such Award held by the
Depository when such taking ceases or expires (if no Event of Default has then
occurred and is continuing), or after the indebtedness secured by this Trust
Deed or due under the Loan and Security Documents shall have been paid in full,
shall be paid to the Person lawfully entitled thereto.

     3.5. The Trustor's Obligation to Restore. If all available proceeds of the
Award are made available to the Trustor for restoration, replacement or
rebuilding pursuant hereto, the Trustor shall be obligated promptly to restore,
replace, rebuild or alter any Improvements or Building Service Equipment
affected by a taking so as to restore the 

                                     - 28 -

Mortgaged Premises to an economically viable whole, all without regard to the
adequacy of the proceeds of an Award, if any, made available to the Trustor.


                                   ARTICLE IV.

                   Assignment of Space Leases, Rents, Profits
                   and Other Income as Further Security, Etc.


     4.1. Assignment of Space Leases, Rents, Issues and Profits. Subject to the
Trustor's rights herein, including those set forth in Section 4.3.2 below, the
Trustor hereby absolutely, presently and irrevocably transfers, assigns and sets
over unto the Beneficiary all right, title and interest of the Trustor in and to
all Space Leases, if any, now or hereafter entered into with respect to all or
any part of the Mortgaged Premises, and all renewals, extensions, subleases or
assignments thereof, and all other occupancy agreements (written or oral), by
concession, license or otherwise, together with all of the rents, income,
receipts, revenues, issues and profits arising therefrom (the "Collateral").

     4.2. The Trustor's Covenants Regarding Space Leases.

     4.2.1. Without the prior consent and approval of the Beneficiary in each
instance, the Trustor will not (a) assign, pledge, hypothecate or otherwise
encumber any of the Space Leases or the rents, income, issue and profits of the
Mortgaged Premises; or (b) enter into any Space Leases affecting the Mortgaged
Premises or any part thereof, unless such Space Lease is expressly subordinate
to the lien of this Trust Deed and to any consolidation, extension, renewal,
recasting or refinancing hereof and the Space Lease provides, in substance, that
in the event of enforcement by the Beneficiary of the remedies provided for by
law or by this Trust Deed, each Space Tenant shall, at the option of the
Beneficiary, enter into a agreement with the Beneficiary which shall provide,
among other things, that (i) such Space Tenant shall attorn to any person
succeeding to the interest of the Trustor as a result of such enforcement and
shall recognize such successor in interest as landlord under such Space Lease
without change in the terms or other provisions thereof, (ii) such successor
shall not be bound by any payment of rent or additional rent for more than one
(1) month in advance or any amendment or modification of any such Space Lease
made


                                     - 29 -

without the Beneficiary's written consent, and (iii) such successor shall not
disturb the possession of the Space Tenant provided certain conditions (as
determined by the Beneficiary) have been satisfied, including, without
limitation, that the Space Tenant shall not be in default under the terms of the
Space Lease; or (c) enter into any Space Leases without the prior written
consent of the Beneficiary unless permitted in Section 6.21 of the Loan
Agreement.

     4.2.2. The Trustor further represents, warrants, covenants and agrees that:

          (a) To the best of its knowledge, each Space Lease is (or, when
     executed, will be) a valid and legally enforceable obligation of the
     parties thereto, in full force and effect.

          (b) With respect to each Space Lease and the Space Tenant security
     deposits thereunder, any and/or all of such security deposits shall be held
     as required by the Space Lease but in no event in a manner other than that
     required by law.

          (c) The Trustor shall, at its sole cost and expense, keep, observe,
     perform and discharge, duly and punctually, all and singular the material
     obligations, terms, covenants, conditions, representations and warranties
     of each Space Lease on the part of the Trustor to be kept, observed,
     performed and discharged.

          (d) (i) Except as herein in this clause (i) expressly provided, the
     Trustor shall, at its sole cost and expense, maintain the Space Leases in
     full force and effect; the Trustor will not waive its rights under or
     materially modify, change, supplement, alter or amend ("Change"), nor shall
     the Trustor surrender (whether partial or total), terminate, cancel or
     subordinate, any of the Space Leases or enter into any Backlease (whether
     through an Affiliate or otherwise), and any such attempted Change,
     surrender, termination, cancellation or subordination or Backlease shall be
     void, unless, in each case, the prior written consent thereto of the
     Beneficiary shall have been obtained. Notwithstanding the foregoing, the
     Trustor may (x) terminate any Space Lease under 10,000 square feet as a
     result of a default by the tenant under such Space Lease and (y) consent to
     any sublease or assignment of any Space Lease under 10,000 square feet

     provided (aa) such termination is being effected in the ordinary course of
     the Trustor's business, (bb) no Event of Default then exists and no event
     has occurred that with the passage of time or the giving of notice or both
     would constitute an Event of Default, and (cc) the Beneficiary determines,
     in its reasonable discretion, that upon the effectiveness of such
     termination, assignment or sublease (i) the Loan to Value Ratio (as defined
     in the Loan Agreement, and taking into consideration the value of all of
     the Projects, as defined in the Loan Agreement) is not greater than 55%,
     and (ii) the Debt Service Coverage Ratio (as defined in the Loan Agreement,
     and taking into consideration the loss of income resulting from such
     termination, assignment or sublease, as projected by the Beneficiary in its
     reasonable discretion) is not less than 1.40:1.0. A material Change shall
     include but not be limited to any material Change in the amount or time of
     payment of the rent or additional rent, the length of term or square
     footage of the premises under any Space Lease or any other Change which
     would materially adversely affect the Trustor's rights under the Space
     Lease, or would affect the Beneficiary's rights under the Space Lease or
     the value of the Space Lease as collateral security for the indebtedness.

               (ii) The Trustor shall, at its sole cost and expense, enforce the
          Space Leases in accordance with their terms; and shall appear in and
          defend any action or proceeding arising to which it is a party under
          or in any manner connected with any of the Space Leases.

          (e) The Trustor shall deliver to the Beneficiary a copy of each notice
     of default sent or received by it relating in any way to any Space Lease
     promptly upon, but in any event within five (5) business days after, its
     sending or receipt thereof.

     4.3. The Trustor's Rights and Powers.

     4.3.1. The Trustor hereby irrevocably, in the name of the Trustor or
otherwise, authorizes and empowers the Beneficiary, and assigns and transfers
unto the Beneficiary, and constitutes and appoints the Beneficiary its true and
lawful attorney-in-fact, coupled with an interest and as its agent, irrevocably,
with full power or substitution for it and in its name, but solely for the
following purposes: (i) to exercise and enforce every right, power, remedy,
authority, option and privilege of the

Trustor under the Space Leases, and as such attorney-in-fact, the Beneficiary
may subordinate, terminate, cancel or modify the Space Leases, accept the
surrender of the Space Leases, give any notice, take any action resulting in
such subordination, termination, cancellation, modification or surrender, give
any authorization, furnish any information, make any demands, execute any
instruments and take any and all other action on behalf of and in the name of
the Trustor which in the opinion of the Beneficiary may be necessary or
appropriate to be given, furnished, made, exercised or taken by the Trustor
under the Space Leases in order to comply therewith, to perform the conditions
thereof or to prevent or remedy any default by the Trustor thereunder or to
enforce any of the Trustor's rights and remedies thereunder, and (ii) to ask,
require, demand, receive and collect and give acquittances for the Income (as
hereinafter defined), and on nonpayment thereof to sue for, recover and receive
the same, and on payment thereof to give sufficient releases, receipts,
discharges and acquittances thereof; to endorse any checks or other instruments
or orders in connection therewith and to file any claims or take any action or
institute any proceedings which the Beneficiary may deem to be necessary or
advisable; provided, however, that the power provided for in this sentence may
not be exercised by the Beneficiary unless an Event of Default shall have
occurred and be continuing. "Income" shall mean all deposits, rents, issues,
profits, revenues, royalties, and other revenue producing arrangements, whether
written or oral, and all monetary benefits of, and/or derived from, and/or sums
payable under and by virtue of the Space Leases and/or the Premises.

     4.3.2. So long as there shall not have occurred and then be continuing any
Event of Default and until such right of the Trustor is terminated by the
Beneficiary as provided in SECTION 4.3.3, the Beneficiary will not exercise its
rights pursuant to SECTION 4.3.1, and notwithstanding anything in Section 4.3.1
to the contrary, the Trustor shall have the right (but limited as hereinafter
provided) to exercise all of its rights under the Space Leases, including,
without limitation, to collect and receive all rents, income, receipts,
revenues, issues and profits arising therefrom, provided that the Trustor shall
at all times comply with, observe and perform, in the exercise of such right,
all of the provisions of this Trust Deed and the other Security Documents
applicable to the Space Leases; provided, further, that no action shall be taken
or failed to be taken by the Trustor which would

impair the Collateral or any other collateral security for the Obligations
provided for in the Security Documents.

     4.3.3. The Beneficiary, upon the occurrence and during the continuance of
an Event of Default, at its option and upon written notice to the Trustor, shall
have the right to terminate the right of the Trustor to exercise its rights
under the Space Leases, and, thereupon, in addition, the Beneficiary, at any
time thereafter, at its option, shall have the complete right, power and
authority hereunder to exercise and enforce all rights, powers, remedies,
authority, options and privileges of the Trustor under the Space Leases in the
name of the Trustor or the Beneficiary, to enforce all obligations of the other
parties to the Space Leases and to exercise and enforce all of its rights and
remedies hereunder and under law not exercisable prior to an Event of Default.

     4.3.4. The Trustor does hereby direct each and all of the Space Tenants
under the Space Leases and all contractual obligors of the Trustor to pay any
Income to the Beneficiary upon written demand for payment thereof by the
Beneficiary without further inquiry. It is understood and agreed, however, that
no such demand shall be made unless an Event of Default shall have occurred and
be continuing. No such Space Tenant or obligor shall be obliged to account to
the Trustor for any amounts paid to the Beneficiary by reason of any payment
made to the Beneficiary pursuant to such demand and, upon any such payment to
the Beneficiary, shall be pro tanto released from their obligations to the
Trustor with respect to such payment. Each Space Tenant shall be permitted to
rely on any communication from the Beneficiary pursuant hereto, and under no
circumstances shall such Space Tenant be obligated to the Trustor for any
payments made to the Beneficiary hereunder. Until such demand is made, the
Trustor is authorized to collect or enforce or continue collecting or enforcing
such Income in accordance with the provisions of this Trust Deed.

     4.3.5. The Beneficiary shall not have any duty as to the collection or
protection of the Collateral or any income thereon or payments with respect
thereto, or as to the preservation of any rights pertaining thereto beyond the
safe custody of any thereof actually in its possession. In no instance shall the
Beneficiary be responsible to lessees for payment of interest upon, or return
of, any lease security deposits, except as provided by law or as provided in the
leases and then only if and to the extent that such deposits are received by the
Beneficiary. The Trustor hereby waives notice of acceptance hereof, and


                                     - 33 -

except as otherwise specifically provided herein or required by provision of law
which may not be waived, hereby waives any and all notices or demands with
respect to any exercise by the Beneficiary of any rights or powers which it may
have or to which it may be entitled with respect to the Collateral.

     4.3.6. The Trustor hereby irrevocably constitutes and appoints the
Beneficiary as the true and lawful attorney-in-fact of the Trustor, which
appointment is coupled with an interest, with full power of substitution, to
proceed from time to time in the Trustor's name in any statutory or
non-statutory proceeding affecting the Trustor or any Collateral, and the
Beneficiary or its nominee may (i) execute and file proof of claim for the full
amount of any Collateral and vote such claims for the full amount thereof (A)
for or against any proposal or resolution, (B) for a trustee or trustees or for
a receiver or receivers or for a committee of creditors and/or (C) for the
acceptance or rejection of any proposed arrangement, plan of reorganization,
composition or extension, and the Beneficiary or its nominee may receive any
payment or distribution and give acquittance therefor and may exchange or
release Collateral; (ii) endorse any draft or other instrument for the payment
of money, execute releases and negotiate and enter into settlements; and (iii)
execute all such other documents or instruments as may be necessary or expedient
to be executed by the Trustor for any of the purposes of this Trust Deed;
provided, however, that the power provided for in this sentence may be exercised
by the Beneficiary only while an Event of Default is continuing. The Beneficiary
shall have no duty to exercise any of the aforesaid rights, privileges or
options and shall not be responsible for any failure to do so or delay in so
doing.

     4.4. Remedies and Entry Upon Default.

     4.4.1. So long as no Event of Default shall have occurred and be
continuing, the Trustor shall have the right to collect (but not more than one
(1) month in advance) and retain all of the rents, gross receipts and other
payments, if any, from the Space Leases and from the Mortgaged Premises
generally, and the Beneficiary agrees that customary initial rent payments,
security deposits and reimbursements by a Space Tenant to the Trustor on account
of alterations made by the Trustor for the benefit of the Space Tenant are
permissible advance payments by the Space Tenant.

     4.4.2. Upon any Event of Default, the Beneficiary may, but shall not be
obligated to:

          (a) terminate the rights of the Trustor referred to in SECTION 4.3
     hereof and exercise all of the powers, rights and remedies provided for in
     SECTION 4.3 hereof, including those to be exercised only from and after an
     Event of Default;

          (b) at any time and from time to time, without notice to, or assent
     by, the Trustor or any other Person, but without affecting any of the
     Obligations, in the name of the Trustor or in the name of the Beneficiary,
     notify the account debtors and obligors on any or all of the Space Leases
     to make payment and performance directly to the Beneficiary, and demand,
     collect, receive, compound and give acquittance for the Space Leases or any
     part thereof; extend the time of payment and performance of, compromise or
     settle for cash, credit or otherwise, upon any terms and conditions, any of
     the Space Leases; endorse to the order of the Beneficiary checks, drafts or
     other orders or instruments for the payment of moneys payable to the
     Trustor which shall be issued in respect of any of the Space Leases; file
     any claims, commence, maintain or discontinue any actions, suits or other
     proceedings deemed by the Beneficiary necessary or advisable for the
     purpose of collecting upon or enforcing any of the Space Leases; and
     execute any instrument and do all other things deemed necessary and proper
     by the Beneficiary to protect and preserve and realize upon the Space
     Leases and/or the other rights contemplated hereby; the Trustor hereby
     irrevocably constitutes and appoints the Beneficiary as such the Trustor's
     lawful attorney-in-fact, coupled with an interest, and its agent for the
     foregoing purposes;

          (c) demand, collect, sue for, attach, levy, recover, receive,
     compromise and adjust, and make, execute and deliver receipts and releases
     for all Income that may then be or may thereafter become due, owing or
     payable with respect to the Premises or any part or parts thereof from any
     present or future lessees, tenants, subtenants or occupants thereof or from
     any present or future contract obligors; and/or

          (d) pay, in such order as the Beneficiary in its sole discretion shall
     determine, from and out of the Income collected in connection with the
     Premises and/or the Collateral or any part or parts

     thereof or from or out of any other funds (less the expense of collection,
     including reasonable attorneys' fees and disbursements), any taxes,
     assessments, water rates, sewer rates, or other government or other charges
     levied, assessed or imposed against the Premises or any part or part
     thereof, and also any and all other charges, costs and expenses which the
     Beneficiary deems necessary or advisable to pay in respect of the
     management or operation of the Premises, including, without limitation, the
     costs of insurance policies, repairs and alterations, commissions for
     renting the Premises or any part or parts thereof, legal expenses in
     enforcing claims, preparing papers or procuring any other services that may
     be required and any amounts payable under or pursuant to any Lease; all
     amounts so paid and expended shall be payable on demand, together with
     interest at the Involuntary Rate from the date incurred until paid, and be
     deemed to be included within the Obligations and secured by this Trust
     Deed; the provisions of this ARTICLE and the rights given to the
     Beneficiary hereby shall inure to the benefit of the Beneficiary even
     though the Beneficiary does not enter and take possession of the Premises;
     any balance remaining after the indebtedness secured hereby and the other
     obligations of the Trustor under the Loan and Security Documents shall have
     been paid in full shall be turned over to the Person lawfully entitled
     thereto. Neither the entry upon and taking possession of the Mortgaged
     Premises, nor the collection and application of the rents, gross receipts
     or other charges thereof, nor any other action taken by the Beneficiary in
     connection therewith, shall cure or waive any default hereunder or waive or
     modify any notice thereof or notice of acceleration of the Note theretofore
     given by the Beneficiary.

     4.4.3. If an Event of Default shall have occurred and be continuing, a
notice in writing by the Beneficiary to the Space Tenants under the Space Leases
advising them that the Trustor has defaulted hereunder and requesting that all
future payments of rent, additional rent or other charges under the Space Leases
be made to the Beneficiary (or its agent) shall be construed as conclusive
authority to such Space Tenants that such payments are to be made to the
Beneficiary (or its agent). Each Space Tenant shall be fully protected in making
such payments to the Beneficiary (or its agent) and be given full credit against
its obligations under the applicable Space Lease to the extent of payments made
to the Beneficiary (or its agent) pursuant to any such notice; and the Trustor
hereby

irrevocably constitutes and appoints the Beneficiary the attorney-in-fact and
agent of the Trustor, coupled with an interest, for the purpose of endorsing the
consent of the Trustor on any such notice.

     4.5. No Obligation of Beneficiary.

     4.5.1. The Beneficiary shall not be obligated to perform or discharge any
obligation of the Trustor as a result of the assignment hereby effected, and the
Trustor hereby agrees to indemnify and hold the Beneficiary harmless from and
against any and all liability, loss or damage which the Beneficiary may incur by
reason of any act of the Beneficiary under this Trust Deed, other than as a
result of the Beneficiary's willful misconduct or gross negligence and other
than as a result of the Beneficiary's misconduct or negligence after the
Beneficiary has taken possession of the Premises. Should the Beneficiary (i)
incur any such liability, loss or damage by reason of this Trust Deed and which
is covered by the foregoing indemnity, or in defense against any such claims or
demands, or (ii) perform any acts or covenants on the part of the Trustor to be
performed under the Space Leases, or (iii) pay for the account of the Trustor
(other than from Income or from funds delivered to the Beneficiary by the
Trustor to be held in Trust for such purpose), any and all sums, costs and
expenses for the discharge of taxes, assessments, water rents or other liens
against the Collateral or any part thereof, or on account of insurance premiums
or repairs, and also any amounts and expenses necessary to perform any covenants
and conditions to be performed on the part of the Trustor under the Space
Leases, the amount thereof, including costs, expenses and reasonable attorneys'
fees, together with interest thereon at the Involuntary Rate from the date such
expenses were paid by the Beneficiary to the date of payment to the Beneficiary
by the Trustor, shall be included in the Obligations secured by this Trust Deed,
and the Trustor shall reimburse the Beneficiary therefor upon demand.

     4.5.2. The acceptance by the Beneficiary of this Trust Deed, with all the
rights, powers, privileges and authority so created, shall not at any time or in
any event obligate the Beneficiary to appear in or defend any action or
proceeding relating to the Collateral, or to take any action hereunder or
thereunder, or to expend any money or incur any expenses or perform or discharge
any obligation, duty or liability under the Collateral.

                Security Agreement Under Uniform Commercial Code

     5.1. This Trust Deed shall constitute a security agreement and a fixture
filing within the meaning of the Uniform Commercial Code of the State (the
"Code"), and the Beneficiary shall be deemed to be the "secured party" (as that
term is defined in the Code). The Trustor hereby grants to the Beneficiary, as
additional collateral for the obligations under the Note and the other
Obligations secured hereby, a security interest in and to all of the Mortgaged
Premises which are considered or as shall be determined to be personal property
or "fixtures" (as defined in the Code), including, without limitation, the
Building Service Equipment, the Furnishings, the Payments and Intangibles, all
books, records, licenses and certificates of the Trustor relating to the
Mortgaged Premises, together with all replacements thereof, substitutions
therefor or additions thereto (said property being sometimes hereinafter
referred to as the "Personal Property"). The Trustor agrees that a security
interest shall attach to the Personal Property for the benefit of the
Beneficiary to secure the indebtedness evidenced by the Note and the other
Obligations secured by this Trust Deed and all other sums and charges which may
become due hereunder, thereunder or under any of the other Security Documents.
The Trustor hereby authorizes the Beneficiary to file financing and continuation
statements with respect to the Personal Property without the signature of the
Trustor, if permitted by the Code. In any event the Trustor covenants to execute
such financing and continuation statements as the Beneficiary may reasonably
request. If an Event of Default shall occur and be continuing, the Beneficiary,
pursuant to the appropriate provisions of the Code, shall have the option of
proceeding as to both real and personal property in accordance with its rights
and remedies in respect of real property under this Trust Deed and the law of
the State, in which event the default provisions of the Code shall not apply.
The Trustor agrees that, in the event the Beneficiary shall elect to proceed
with respect to the Personal Property separately from the real property, unless
a greater period shall then be mandated by the Code, five (5) days notice of the
sale of the Personal Property shall be reasonable notice. The expenses of
retaking, holding, preparing for sale and selling incurred by the Beneficiary
shall be assessed against the Trustor and shall include, but not be limited to,
the reasonable legal expenses incurred by Beneficiary. The Trustor agrees that
it will not remove or permit to be removed from the Mortgaged Premises any of
the Personal

Property without the prior written consent of the Beneficiary except as set
forth in SECTION 2.7.2. All replacements, renewals and additions to the Personal
Property shall be and become immediately subject to the security interest of
this Trust Deed and the provisions of this ARTICLE V. The Trustor warrants and
represents that all Personal Property now is free and clear of all liens,
encumbrances or security interests other than the Permitted Encumbrances, and
that all replacements of the Personal Property, substitutions therefor or
additions thereto, unless the Beneficiary otherwise consents, will be, free and
clear of liens, encumbrances or security interests of others.


                                   ARTICLE VI.

                         Events of Default and Remedies


     6.1. Events of Default. The whole of the outstanding Principal Amount (as
defined in the Note) and accrued interest evidenced by the Note shall, at the
option of the Beneficiary, become due upon the happening of an Event of Default.

     6.2. Remedies.

     6.2.1. If an Event of Default shall occur and be continuing, the
Beneficiary, at its option, may:

          (a) by notice to the Trustor, declare the entire principal amount of
     the Note then outstanding and all accrued and unpaid interest thereon and
     all obligations of the Trustor to the Beneficiary to be immediately due and
     payable, and upon such declaration such principal and interest and all
     obligations of the Trustor to the Beneficiary shall become and be
     immediately due and payable, anything in the Note, the Loan Agreement or in
     this Trust Deed or in any of the other Security Documents to the contrary
     notwithstanding;

          (b) as a matter of right and without notice to the Trustor or anyone
     claiming under the Trustor, and without regard to the then value of the
     Mortgaged Premises or the interest of the Trustor therein, to apply to any
     court having jurisdiction to appoint a receiver or receivers of the
     Mortgaged Premises, and the Trustor hereby irrevocable consents to such
     appointment and waives notice of any application therefor; any such
     receiver or receivers

     shall have all the usual powers and duties of receivers in like or similar
     cases and all the powers and duties of the Beneficiary in case of entry as
     provided in this Trust Deed, and shall continue as such and exercise all
     such powers until the later of (i) the date of confirmation of sale of the
     Mortgaged Premises, (ii) the disbursement of all proceeds of the Mortgaged
     Premises collected by such receiver and the payment of all expenses
     incurred in connection therewith, and (iii) the termination of such
     receivership with the consent of the Beneficiary or pursuant to an order by
     a court of competent jurisdiction;

          (c) exercise any and all remedies available to a secured party under
     the UCC in such order and in such manner as the Beneficiary in its sole
     discretion may determine; provided, however, that the expenses of retaking,
     holding, preparing for sale or the like, shall include reasonable
     attorneys' fees and other expenses of the Beneficiary and the Trustee and
     be secured by this Trust Deed;

          (d) bring an action in any court of competent jurisdiction to
     judicially foreclose this Trust Deed or enforce any of the terms, covenants
     and conditions hereof or contained in any other Security Document;

          (e) require the Trustee to sell all or part of the Mortgaged Premises,
     at public auction, to the highest bidder, for cash, at the county
     courthouse of the county in Texas in which such Premises or any part hereof
     is situated, between the hours of 10:00 o'clock a.m. and 4:00 o'clock p.m.
     on the first Tuesday of any month, after giving notice of the time, place
     and terms of said sale and of the property to be sold, by posting written
     notice thereof at the courthouse door of the county, and filing such notice
     with the County Clerk of the county in which the sale is to be made at
     least twenty-one (21) days preceding the date of the sale, and if the
     property to be sold is in more than one county, a notice shall be posted at
     the courthouse door and filed with the County Clerk of each county in which
     the property to be sold is situated. In addition, the Beneficiary shall, at
     least twenty-one (21) days preceding the date of sale, serve written notice
     of the proposed sale by certified mail on each debtor obligated to pay the
     debt secured hereby according to the records of the Beneficiary. Service of
     such notice shall be completed upon deposit of the notice, enclosed in a
     postpaid wrapper, properly addressed to such debtor at the most recent
     address as shown by the records of the Beneficiary, in a post office or
     official depository under the care and custody of the United

     States Postal Service. The affidavit of any person having knowledge of the
     facts to the effect that such service was completed shall be prima facie
     evidence of the fact of service. Any notice that is required or permitted
     to be given to the Trustor may be addressed to the Trustor at the Trustor's
     address as stated above. Any notice that is to be given by certified mail
     to any other debtor may, if no address for such other debtor is shown by
     the records of the Beneficiary, be addressed to such other debtor at the
     address of the Trustor as is shown by the records of the Beneficiary.
     Notwithstanding the foregoing provisions of this paragraph, notice of such
     sale given in accordance with the requirements of the applicable laws of
     the State of Texas in effect at the time of such sale shall constitute
     sufficient notice of such sale.. The Trustee may sell all or any portion of
     the Mortgaged Premises, together or in lots or parcels, and may execute and
     deliver to the purchaser or purchasers of such property good and sufficient
     deeds of conveyance of fee simple title with covenants of special warranty
     made on behalf of the Trustor. In no event shall the Trustee be required to
     exhibit, present or display at any such sale any of the personalty
     described herein to be sold at such sale. The Trustee making such sale
     shall receive the proceeds thereof and shall apply the same as follows: (i)
     first, they shall pay the reasonable expenses and actual fees (based upon
     time spent) of the Trustee; (ii) second, they shall pay, so far as may be
     possible, the Obligations, discharging first that portion of the
     Obligations arising under the covenants or agreements herein contained and
     not evidenced by the Note; (iii) third, they shall pay the residue, if any,
     to the persons legally entitled thereto. Payment of the purchase price to
     the Trustee shall satisfy the obligation of the purchaser at such sale
     therefor, and such purchaser shall not be responsible for the application
     thereof. The sale or sales by the Trustee of less than the whole of the
     Mortgaged Premises shall not exhaust the power of sale herein granted, and
     the Trustee is specifically empowered to make a successive sale or sales
     under such power until the whole of the Mortgaged Premises shall be sold;
     and if the proceeds of such sale or sales of less than the whole of the
     Mortgaged Premises shall be less than the aggregate of the Obligations and
     the expenses thereof, this Trust Deed and the lien, security interest and
     assignment hereof shall remain in full force and effect as to the unsold
     portion of the Mortgaged Premises just as though no sale or sales had been
     made; provided, however, that the Trustor shall never have any right to
     require the sale or sales of less than the whole of the Mortgaged Premises,
     but the Beneficiary shall have the

     right, at its sole discretion, to request the Trustee to sell less than the
     whole of the Mortgaged Premises;

          (f) proceed by a suit or suits in equity or at law, whether for the
     specific performance of any covenant or agreement herein contained or in
     aid of the execution of any power herein granted, or for any foreclosure
     hereunder or for the sale of the Mortgaged Premises under the judgment or
     decree of any court or courts of competent jurisdiction; and/or

          (g) exercise any or all of its other rights and remedies provided
     herein, in any of the Security Documents, or other document or agreement
     now or hereafter securing all or any portion of the Obligations secured
     hereby, or as provided by law, in such order of priority as the Beneficiary
     shall determine in its sole discretion.

     6.2.2. If default is made hereunder, the holder of the Obligations or any
part thereof on which the payment is delinquent shall have the option to proceed
with foreclosure in satisfaction of such item either through judicial
proceedings or by directing the Trustee to proceed as if under a full
foreclosure, conducting the sale as herein provided without declaring the entire
Obligations due, and if sale is made because of default of an installment, or a
part of an installment, such sale may be made subject to the unmatured part of
the Obligations; and it is agreed that such sale, if so made, shall not in any
manner affect the unmatured part of the Obligations, but as to such unmatured
part this Trust Deed shall remain in full force and effect as though no sale has
been made under the provisions of this paragraph.

     6.2.3. Several sales may be made hereunder without exhausting the right of
sale for any unmatured part of the Obligations. At any such sale the Trustor
hereby agrees, on its behalf and on behalf of its heirs, executors,
administrators, successors, personal representatives and assigns, that any and
all recitals made in any deed of conveyance given by the Trustee with respect to
the identity of the Beneficiary, the occurrence or existence of any default, the
acceleration of the maturity of any of the Obligations, the request to sell, the
notice of sale, the giving of notice to all debtors legally entitled thereto,
the time, place, terms, and manner of sale, and receipt, distribution and
application of the money realized therefrom, or the due and proper appointment
of any substitute trustee, and without being limited by the foregoing, with
respect to any other act or thing having

been duly done by the Beneficiary or by the Trustee hereunder, shall be taken by
all courts of law and equity as prima facie evidence that the statements or
recitals state facts and are without further question to be so accepted, and the
Trustor hereby ratifies and confirms every act that the Trustee or any
substitute the trustee hereunder may lawfully do in the premises by virtue
hereof. The Beneficiary may bid and become the purchaser of all or any part of
the Mortgaged Premises at any the trustee's or foreclosure sale hereunder, and
the amount of the Beneficiary's successful bid may be credited on the
Obligations.

     6.2.4. This Trust Deed is granted upon this express condition, that if the
Trustor, or its successors or assigns, shall pay or cause to be paid to the
Beneficiary or its successors or assigns all of the Obligations secured hereby,
in accordance with their terms, and shall well and truly comply with each and
every covenant and condition set forth in this Trust Deed, in the Note, and in
the Security Documents, then, except for the covenants, agreements,
indemnifications and warranties, if any, in this Trust Deed which expressly
survive the release hereof, the Premises shall be released from the lien of this
Trust Deed at the cost of the Trustor. Otherwise, this Trust Deed shall remain
in full force and effect. Upon the occurrence of any Event of Default under the
Loan Agreement, including but not limited to any breach of the covenants and
agreements of, and conditions imposed upon, the Trustor contained herein and in
the Note, the Loan Agreement, and the other instruments and agreements
evidencing or securing the Obligations secured hereby, which breach remains
uncured beyond the grace period, if any, provided herein or therein, or in the
Loan Agreement, the Beneficiary may proceed to protect and enforce its rights
hereunder and under the Note and the other Security Documents by foreclosure
proceedings, or by other suit in equity, action at law, or other appropriate
proceedings, including actions for the specific performance of any covenant or
agreement contained in this Trust Deed or in the Note, or in the other Security
Documents, or in aid of the exercise of any power granted in this Trust Deed,
the Note, or in said Security Documents, or may proceed in any other legal or
equitable right of the Beneficiary and of the holder of the Note.

     6.3. Sale; No Marshalling of Assets.

     6.3.1. In case of a foreclosure sale, all of the Mortgaged Premises may be
sold in one parcel even though the proceeds of such sale exceed or may exceed
the

indebtedness secured hereby. The Beneficiary shall not be required to exercise
any rights under this Trust Deed before proceeding against any other security,
shall not be required to proceed against other security before proceeding under
this Trust Deed, and shall not be precluded from proceeding against any or all
of any security held by the Beneficiary for any or all of the indebtedness
secured hereby in any order or at the same time.

     6.3.2. The Trustor agrees, to the full extent that it may lawfully do so,
that in any foreclosure or other action brought by the Beneficiary to enforce
this Trust Deed, it will not at any time insist upon or plead or in any way take
advantage of any appraisement, valuation, stay, marshalling of assets,
extension, redemption or moratorium law now or hereafter in force and effect so
as to prevent, hinder, delay or otherwise affect the enforcement of the
provisions of this Trust Deed or any rights or remedies the Beneficiary may have
hereunder or by law.

     6.3.3. If the Beneficiary shall elect to accelerate the indebtedness
secured hereby following the occurrence of an Event of Default, the Trustor,
within five (5) days after demand, will pay to the Beneficiary, or any receiver
appointed in connection with the foreclosure of this Trust Deed, any and all
amounts then held as security deposits under all Space Leases; and the
Beneficiary or such receiver shall be deemed to indemnify the Trustor against
all claims of tenants in respect of the security deposits so paid following such
demand.

     6.4. Legal Expenses of the Beneficiary.

     6.4.1. The Trustor will pay to the Beneficiary or the Trustee, as the case
may be, on demand, all costs, charges and expenses (including, without
limitation, reasonable attorneys' fees and disbursements) incurred or paid at
any time by the Beneficiary or the Trustee (i) in connection with any action or
proceeding to foreclose this Trust Deed or to recover or collect all, or any
portion of the indebtedness secured hereby; and (ii) in connection with any
modification or amendment or assignment of this Trust Deed or the other Security
Documents, together with interest on each such payment made by the Beneficiary
at the Involuntary Rate from the date of the Beneficiary's demand for such
payment to the date of reimbursement by the Trustor.

     6.4.2. If any action or proceeding be commenced in which the Beneficiary or
the Trustee is made a

party, or in which it becomes necessary to defend or uphold the lien of this
Trust Deed, all reasonable sums paid by the Beneficiary for the expense of any
litigation to prosecute or defend the title, rights and lien created by this
Trust Deed (including, without limitation, reasonable attorneys' fees) shall be
paid by the Trustor, together with interest thereon at the Involuntary Rate from
the date of the Beneficiary's demand for such payment to the date of
reimbursement by the Trustor.

     6.5. Remedies Cumulative; No Waiver; Etc.

     6.5.1. No remedy in this Trust Deed conferred upon or reserved to the
Beneficiary is intended to be exclusive of any other remedy or remedies, and
each and every such remedy shall be cumulative, and shall be in addition to
every other remedy given hereunder or now or hereafter existing at law or in
equity. No delay or omission by the Beneficiary in exercising any right or power
arising upon any Event of Default shall impair any such right or power, or shall
be construed to be a waiver of or acquiescence in any such Event of Default; and
every power and remedy given by this Trust Deed to the Beneficiary may be
exercised from time to time as often as the Beneficiary may determine it is
appropriate to do so.

     6.5.2. A waiver in one or more instances of compliance with any of the
terms, covenants, conditions or provisions of the Note, the Loan Agreement or of
the Security Documents shall apply to the particular instance or instances and
at the particular time or times only, and no such waiver shall be deemed a
continuing waiver. In any event, no waiver shall be effective, or be asserted by
the Trustor as having been made, unless set forth in a writing signed by the
Beneficiary.

     6.5.3. The Trustor waives and renounces all homestead and similar exemption
rights with respect to the Mortgaged Premises provided for by the Constitution
and laws of the United States and of the State as against the collection of the
Security Documents, or any part thereof.

     6.6. No Merger. It is the intention of the parties to this Trust Deed that
if the Beneficiary or the Trustee shall at any time hereafter acquire title to
all or any portion of the Mortgaged Premises, then, and until the indebtedness
secured hereby has been paid in full, the interest of the Beneficiary hereunder
and the lien of this Trust Deed shall not merge or become merged in or with the
estate and interest of the Beneficiary or the Trustee as the

holder and owner of title to all or any portion of the Mortgaged Premises and
that, until such payment, the estate of the Beneficiary or the Trustee in the
Mortgaged Premises and the lien of this Trust Deed and the interest of the
Beneficiary hereunder shall continue in full force and effect to the same extent
as if the Beneficiary or the Trustee had not acquired title to all or any
portion of the Mortgaged Premises.

releasing the Trustor from any obligation or default hereunder, after giving any
notice to the Trustor required hereunder and after the passage of any applicable
cure periods (or without such notice in the event of an emergency), the
Beneficiary (or any receiver of the Mortgaged Premises) shall have the right,
but not the obligation, to make any such payment, or to perform any other act or
take any appropriate action, including, without limitation, entry on the
Mortgaged Premises and performance of work thereat, as it, in its sole
discretion, may deem necessary to cause such other term, covenant, condition or
obligation to be promptly performed or observed on behalf of the Trustor or to
protect the security of this Trust Deed. All amounts advanced by, or on behalf
of, the Beneficiary in

legal expenses and disbursements incurred in connection therewith), together
with interest thereon at the Involuntary Rate from the date of the Beneficiary's
demand upon the Trustor for reimbursement of such sums until reimbursement by
the Trustor, shall be payable by the Trustor to the Beneficiary upon demand and
shall be secured by this Trust Deed.

     7.4. Additional Sums Payable by the Trustor. All sums which, by the terms
of this Trust Deed or any of the other Security Documents (excluding however the
principal indebtedness evidenced by the Note), are payable by the Trustor to the
Beneficiary shall, together with the interest thereon provided for herein or in
the Note or such other Security Documents, be added to and deemed part of the
indebtedness secured by the lien of this Trust Deed whether or not the provision
which obligates the Trustor to make any such payment to the Beneficiary
specifically so states.

     7.5. Captions. The captions used in this Trust Deed are inserted only as a
matter of convenience and for reference, and in no way define, limit, enlarge or
describe the scope or intent of this Trust Deed or in any other way affect this
Trust Deed or the construction of any provision hereof.

     7.6. Successors and Assigns. The covenants and agreements contained in this
Trust Deed shall run with the land and bind the Trustor, the successors and

event, be construed as if such invalid, illegal or unenforceable provision had
never been included.

     7.9. Usury. Anything in the Note, the Loan Agreement, this Trust Deed or
the other Security Documents to the contrary notwithstanding, the Beneficiary
shall never be entitled to receive, collect or apply as interest on the
principal amount of the Note or any other of the obligations secured hereby any
amount in excess of the maximum rate of interest permitted to be charged by
applicable law. In the event the Beneficiary ever receives, collects or applies
as interest any such excess, the amount which would be excessive interest shall
be applied to the reduction of the principal amount of said obligations; and if
said principal amount shall have been paid in full, shall be remitted to the
Person lawfully entitled thereto. In determining whether or not the interest
paid or payable in any specific instance shall exceed the highest lawful rate,
the Trustor and the Beneficiary shall to the maximum extent permitted by
applicable law (i) characterize any non-principal payment as an expense, fee or
premium rather than as interest, (ii) exclude voluntary prepayments and the
effects thereof and (iii) "spread" the total amount of interest throughout the
entire contemplated terms of the obligations so that the interest rate is
uniform throughout the entire said term.

     7.10. Controlling Law. This Trust Deed shall be governed by, and construed
and enforced in accordance with the laws of the State of Texas applicable to
contracts made and to be wholly performed within such state.

     7.11. Entire Agreement. This Trust Deed, together with the Note, the Loan
Agreement and the other Security Documents, embodies the entire agreement and
understanding between the parties relating to the subject matter hereof.

     1. All judgments and liens noted in Item 9 of Schedule B of the Certificate

mortgagee's title insurance policy issued at the Closing, and at Closing, Seller
shall deliver to the Title Company, Purchaser and Purchaser's lender an
indemnification agreement in form, scope and substance sufficient to omit said
Item 9 and reasonably acceptable to Seller, (and which indemnification agreement
shall be freely assignable by Purchaser and Purchaser's lender) indemnifying and
holding the Title Company, Purchaser and Purchaser's lender (and Purchaser's and
Purchaser's lender's respective successors and assigns) harmless from and
against any and all judgments and liens noted in said Item 9.

     2. All judgments noted in Item 10 of Schedule B of the Certificate of Title
shall be omitted as an exception to title from any owner's and mortgagee's title
insurance policy issued at the Closing, and at Closing, Seller shall deliver to
the Title Company, Purchaser and Purchaser's lender an indemnification agreement

lender's

                                        3

<PAGE>



respective successors and assigns) harmless from and against any and all
judgments noted in said Item 10.

     3. Item No. 19 shall be omitted as an exception to title from any owner's
and mortgagee's title insurance policy issued at the Closing.

     4. Seller shall deliver at Closing such affidavits as may be customarily
and reasonably required by the Title Company, in a form reasonably acceptable to
Seller, including, but not limited to, those specific affidavits required by

policy issued at the Closing.

     5. Subject to adjustment as herein provided, all open taxes, assessments,
vault charges and other similar charges noted and set forth in the Existing
Title and Survey Matters shall be satisfied in full at or prior to Closing.

     6. All violations of federal, state, New York City, municipal and local
laws, regulations, ordinances, permits and the like noted and set forth in the
Existing Title and Survey Matters shall be cured prior to Closing, except for
(a) those certain violations noted as Items 1 and 2 on Exhibit R attached hereto
(the "Violations"), regarding which Seller shall attempt to cure prior to
Closing; provided, however, (i) Seller shall not be obligated to cure the
Violations as a condition to Closing; (ii) the failure by Seller to cure the
Violations on or before Closing shall not be a default of Seller's obligations
under this Agreement; and (ii) if Seller fails to cure the Violations on or
before Closing, Seller shall not be obligated to continue to attempt to cure the
Violations (but Seller (at no cost to Seller) shall reasonably cooperate with
Purchaser to effectuate such cure); and (b) that certain violation noted as Item
3 on Exhibit R attached hereto.

     7. Seller shall deliver at Closing such affidavit as may be customarily and
reasonably required by the Title Company, in a form reasonably acceptable to
Seller, regarding tenants referenced in Item 2 of Schedule B of the Certificate
of Title.

     The Existing Title and Survey Matters, as modified, cured and affected
hereinabove, shall be referred to as the "Acceptable Title Matters").

     Section 2.2 Pre-Closing "Gap" Title Defects. Purchaser may, at or prior to
Closing, notify Seller in writing (the "Gap Notice") of any objections to title
not disclosed by the Title Company or otherwise known to Purchaser on or before
the Title Inspection Date; provided that Purchaser must notify Seller of such
objection to title within two (2) business days of being made aware of the
existence of such exception. If Purchaser sends a Gap Notice to Seller, Seller
shall notify Purchaser within five (5) business days thereafter whether Seller,
at Seller's option, shall either (a) remove such objectionable exceptions from
title on or

                                        4

<PAGE>



before the Closing; provided that Seller may extend the Closing for such period
as shall be required to effect such cure, but not beyond thirty (30) days; or
(b) not cause such exceptions to be removed. If Seller does not notify Purchaser
with said five (5) business day period, Seller shall be deemed to have elected
not to cause such objectionable exceptions from title. The procurement by Seller
of a commitment for the issuance of the Title Policy (as defined in Section 2.4
hereof) shall be deemed a cure by Seller of such objections set forth in the Gap
Notice. If Seller gives Purchaser notice under clause (b) above, Purchaser shall
have five (5) business days (but in all events must do so at or prior to the
Closing) in which to notify Seller that Purchaser will nevertheless proceed with
the purchase and take title to the Property subject to such exceptions, or that
Purchaser will terminate this Agreement. If this Agreement is terminated
pursuant to the foregoing provisions of this paragraph, then neither party shall
have any further rights or obligations hereunder (except for any indemnity
obligations of either party pursuant to the other provisions of this Agreement
other than the obligations set forth in Article 11 hereof, which shall void and
thereupon of no force or effect), the Deposit shall be returned to Purchaser and
each party shall bear its own costs incurred hereunder. If Purchaser shall fail
to notify Seller of its election within said five (5) business day period,
Purchaser shall be deemed to have elected to proceed with the purchase and take
title to the Property subject to such exceptions.

     Section 2.3 Permitted Exceptions. The Property shall be conveyed subject to
the following matters, which are hereinafter referred to as the "Permitted
Exceptions":

     (a) each and all of the Acceptable Title Matters;

     (b) matters that either are not objected to in writing within the time
periods provided in Sections 2.2, or if objected to in writing by Purchaser, are
those which Seller has elected not to remove or cure, or has been unable to
remove or cure, and subject to which Purchaser has elected or is deemed to have
elected to accept the conveyance of the Property;

     (c) the rights of tenants under the Leases as tenants only;

     (d) the lien of all ad valorem real estate taxes and assessments not yet
due and payable as of the date of Closing, subject to adjustment as herein
provided; and

     (e) local, state and federal laws, ordinances or governmental regulations,
including but not limited to, building and zoning laws, ordinances and
regulations, now or hereafter in effect relating to the Property.

     Section 2.4 Conveyance of Title. At Closing, Seller shall convey and
transfer to Purchaser fee simple title to the Land and the Improvements, by
execution and delivery of the Deed (as defined in Section 4.2(a) hereof).
Evidence of delivery of such title

                                        5

shall be the issuance by the Title Company of a 1992 ALTA Owner's Policy of
Title Insurance (the "Title Policy") covering the Real Property, in the full
amount of the Purchase Price, subject only to the Permitted Exceptions.

                                   ARTICLE III
                               REVIEW OF PROPERTY

     Section 3.1 Right of Inspection. Purchaser acknowledges and agrees that it
has had an opportunity, prior to the Effective Date, to make any and all
physical and other inspections of the Property as Purchaser has deemed necessary
and/or appropriate in connection with the transaction contemplated by this
Agreement, and that Purchaser has agreed, subject to the provisions of Article
VII hereof, to accept the Property at the Closing in the condition that exists
on the Effective Date, reasonable wear and tear excepted. Purchaser shall have
the right to further inspect the Property within the two (2) day period
immediately preceding the Closing (during normal business hours and upon notice
to Seller) for the sole purpose of confirming that the Property is in the same
condition at the Closing as existed on the Effective Date, reasonable wear and
tear excepted, as aforesaid.

     Section 3.2 Reports. PURCHASER ACKNOWLEDGES THAT (1) PURCHASER HAS RECEIVED
COPIES OF THE REPORTS LISTED ON EXHIBIT F ATTACHED HERETO, (2) IF SELLER
DELIVERS ANY ADDITIONAL REPORTS TO PURCHASER, PURCHASER WILL ACKNOWLEDGE IN
WRITING THAT IT HAS RECEIVED SUCH REPORTS PROMPTLY UPON RECEIPT THEREOF, AND (3)
ANY REPORTS DELIVERED OR TO BE DELIVERED BY SELLER OR ITS AGENTS OR CONSULTANTS
TO PURCHASER ARE BEING MADE AVAILABLE SOLELY AS AN ACCOMMODATION TO PURCHASER
AND MAY NOT BE RELIED UPON BY PURCHASER IN CONNECTION WITH THE PURCHASE OF THE
PROPERTY. PURCHASER AGREES THAT SELLER SHALL HAVE NO LIABILITY OR OBLIGATION
WHATSOEVER FOR ANY INACCURACY IN OR OMISSION FROM ANY REPORT. PURCHASER
ACKNOWLEDGES AND AGREES THAT IT HAS CONDUCTED, PRIOR TO THE EFFECTIVE DATE, ITS
OWN INVESTIGATION OF THE CONDITION OF THE PROPERTY TO THE EXTENT PURCHASER
DEEMED SUCH AN INVESTIGATION TO BE NECESSARY OR APPROPRIATE, AND PURCHASER HAS
APPROVED OF THE CONDITION OF THE PROPERTY.

     Section 3.3 Review of Tenant Estoppels. Within five (5) days of the
Effective Date, Seller shall deliver to each tenant of the Property an estoppel
certificate in substantially the form of Exhibit G attached hereto (the "Tenant
Estoppels") and shall request that the tenants complete and sign the Tenant
Estoppels and return them to Seller; provided, however, Purchaser acknowledges
that each tenant shall only be obligated to return an estoppel certificate as
set forth in said tenant's lease. Seller shall deliver copies of the completed
Tenant Estoppels to Purchaser as Seller receives them and deliver the originals
thereof to Purchaser at the Closing. Purchaser shall notify Seller within three
(3) business days of receipt of any Tenant Estoppel in the event Purchaser
determines such Tenant Estoppel is not reasonably acceptable to Purchaser along
with the reasons for such determination. In the event Purchaser fails to give
such notice

                                        6

<PAGE>



within such three (3) business day period then any such Tenant Estoppel shall be
deemed to be acceptable to Purchaser. In the event that Seller fails to obtain
the Tenant Estoppels or at a minimum, estoppel certificates containing the
information required under said tenants' leases (or in lieu thereof (except for
Flack & Kurtz), at Seller's option, Seller estoppels therefor in the form of the
Tenant Estoppel set forth in Exhibit G for not more than ten (10%) percent of
the currently occupied space at the Property as of the Effective Date) that are
reasonably satisfactory to Purchaser on or before three (3) business days prior
to Closing from (a) Flack & Kurtz and (b) those tenants occupying at least sixty
(60%) percent of the rentable square feet of the Property (which shall include
the rentable square feet occupied by Flack & Kurtz), in the aggregate, then
Purchaser shall have the right to terminate this Agreement by written notice to
Seller. If this Agreement is terminated pursuant to the foregoing provisions of
this paragraph, then neither party shall have any further rights or obligations
hereunder (except for any indemnity obligations of either party pursuant to the
other provisions of this Agreement other than the obligations set forth in
Article 11 hereof, which shall void and thereupon of no force or effect), the
Deposit shall be returned to Purchaser and each party shall bear its own costs
incurred hereunder. If Purchaser fails to give Seller a notice of termination as
set forth above, Purchaser shall be deemed to have approved the Tenant Estoppels
(and Seller estoppels, if applicable) and to have elected to proceed with the
purchase of the Property pursuant to the terms hereof. Except as otherwise
provided in the succeeding sentence, the representations and warranties set
forth in any Seller estoppels shall survive the Closing for a period of one (1)
year and Seller's liability to Purchaser for a breach of any representation or
warranty set forth in any Seller estoppels shall be subject to Section 5.3
hereof. Any Tenant Estoppel which is received from a tenant after Seller
provides its own estoppel may be substituted for Seller's estoppel and Seller
shall have no further liability thereunder, provided that such Tenant Estoppel
contains no changes or, if changed, is otherwise reasonably acceptable to
Purchaser. The provisions of this Section 3.4 shall survive the Closing.

                                   ARTICLE IV
                                     CLOSING

contemplated hereby (the "Closing") shall be held at the offices of Seller
located at 200 Park Avenue, 12th Floor, New York, New York on December 4, 1996,
at 9:30 A.M. At the Closing, Seller and Purchaser shall perform the obligations
set forth in, respectively, Section 4.2 and Section 4.3 hereof, the performance
of which obligations shall be concurrent conditions; provided that the Deed
shall not be recorded until Seller receives confirmation that Seller has
received the full amount of the Purchase Price, adjusted by prorations as set
forth herein.

     Section 4.2 Seller's Obligations at Closing. At Closing, Seller shall:

                                        7

     (a) deliver to Purchaser a duly executed Bargain and Sale Deed without
Covenants Against Grantor's Acts (the "Deed") in the form attached hereto as

Permitted Exceptions. Subject to the terms of this Agreement, at Seller's
option, and for convenience, Seller may omit from the Deed the recital of any or
all of the "subject to" clauses concerning the Permitted Exceptions, but the
same shall nevertheless survive the Closing. The terms of the immediately
preceding sentence shall survive the Closing;

     (b) deliver to Purchaser a duly executed bill of sale (the "Bill of Sale")
conveying the Personal Property without warranty of title or use and without
warranty, express or implied, as to merchantability and fitness for any purpose
and in the form attached hereto as Exhibit I;

and against any and all claims pertaining thereto arising from and after the
Closing, including without limitation, claims made by tenants with respect to
tenants' Security Deposits to the extent paid, credited or assigned to
Purchaser;

     (d) to the extent assignable, assign to Purchaser, and Purchaser shall
assume, Seller's interest in the Operating Agreements and the other Intangibles
by duly executed assignment and assumption agreement (the "Assignment of
Contracts") in the form attached hereto as Exhibit K pursuant to which Purchaser
shall indemnify Seller and hold Seller harmless from and against any and all
claims pertaining thereto arising from and after the Closing;

     (e) join with Purchaser to execute a notice (the "Tenant Notice") in the
form attached hereto as Exhibit L, which Purchaser shall send to each tenant
under each of the Leases promptly after the Closing, informing such tenant of
the sale of the Property and of the assignment to Purchaser of Seller's interest
in, and obligations under, the Leases (including, if applicable, any Security
Deposits), and directing that all Rent and other sums payable after the Closing
under each such Lease be paid as set forth in the notice;

     (f) In the event that any representation or warranty of Seller needs to be
modified due to changes since the Effective Date, deliver to Purchaser a
certificate, dated as of the date of Closing and executed on behalf of Seller by

Purchaser for, or be deemed to be in default hereunder by reason of, any breach
of representation or warranty which results from any change that (i) occurs
between the Effective Date and the date of Closing, and (ii) is expressly
permitted under the terms of this Agreement or is beyond the reasonable control
of Seller to prevent; provided, however, that the occurrence of a change which
is not permitted hereunder or is beyond the reasonable control of Seller to
prevent shall, if materially adverse to Purchaser, constitute the
non-fulfillment of the condition set forth in Section 4.6(b) hereof; if, despite
changes or other matters described in such certificate, the Closing occurs,
Seller's representations and warranties set forth in this Agreement shall be
deemed to have been modified by all statements made in such certificate;

     (g) deliver to Purchaser such evidence as the Title Company may reasonably
require as to the authority of the person or persons executing documents on
behalf of Seller;

     (h) deliver to Purchaser a certificate in the form attached hereto as

and at all reasonable times, to examine and make copies of any and all such

identifying any such representation or warranty which is not, or no longer is,
true and correct and explaining the state of facts giving rise to the change. In
no event shall Purchaser be liable to Seller for, or be deemed to be in default
hereunder by reason of, any breach of representation or warranty set forth in
Sections 5.5(a) or (b) hereof which results from any change that (i) occurs
between the Effective Date and the date of Closing, and (ii) is expressly
permitted under the terms of this Agreement or is beyond the reasonable control
of Purchaser to prevent; provided, however, that the occurrence of a change
which is not permitted hereunder or is beyond the reasonable control of
Purchaser to prevent shall, if materially adverse to Seller, constitute the
non-fulfillment of the condition set forth in Section 4.7(c) hereof; if, despite
changes or other matters described in such certificate, the Closing occurs,
Purchaser's representations and warranties set forth in this Agreement shall be
deemed to have been modified by all statements made in such certificate;

     obligations of Purchaser set forth in Article 11 hereof.

     (b) Notwithstanding anything contained in Section 4.4(a) hereof:

          (i) At Closing, (A) Seller shall, at Seller's option, either deliver
     to Purchaser any Security Deposits actually held by Seller pursuant to the
     Leases or credit to the account of Purchaser the amount of such Security
     Deposits (to the extent such Security Deposits have not been applied
     against delinquent Rents or otherwise as provided in the Leases), and (B)
     Purchaser shall credit to the account of Seller all refundable cash or
     other deposits posted with utility companies serving the Property, or, at
     Seller's option, Seller shall be entitled to receive and retain such
     refundable cash and deposits. Any Security Deposits in form other than cash
     (including, but not limited to, any letters of credit) shall be transferred
     to Purchaser by way of appropriate instruments of replacement, transfer or
     assignment, the cost of which shall be borne by Purchaser;

          (ii) Any taxes paid at or prior to Closing shall be prorated based
     upon the amounts actually paid. If taxes and assessments due and payable
     during the year of Closing have not been paid before Closing, Seller shall
     be charged at Closing an amount equal to that portion of such taxes and
     assessments which relates to the period before Closing and Purchaser shall
     pay the taxes and assessments prior to their becoming delinquent. Any such

                                       11

<PAGE>



     apportionment made with respect to a tax year for which the tax rate or
     assessed valuation, or both, have not yet been fixed shall be based upon
     the tax rate and/or assessed valuation last fixed. To the extent that the
     actual taxes and assessments for the current year differ from the amount
     apportioned at Closing, the parties shall make all necessary adjustments by
     appropriate payments between themselves within thirty (30) days after such
     amounts are determined following Closing, subject to the provisions of
     Section 4.4(d) hereof;

          (iii) Charges referred to in Section 4.4(a) hereof which are payable
     by any tenant to a third party shall not be apportioned hereunder, and
     Purchaser shall accept title subject to any of such charges unpaid and
     Purchaser shall look solely to the tenant responsible therefor for the
     payment of the same. As of the Effective Date, Seller has not paid any of
     such charges on behalf of any tenant. However, if Seller (after obtaining
     Purchaser's prior written consent, which consent shall not be unreasonably
     withheld or delayed) shall pay any of such charges on behalf of any tenant
     between the Effective Date and the Closing, and shall not have been
     reimbursed therefor by the time of Closing, Purchaser shall credit to
     Seller an amount equal to all such charges so paid by Seller;

          (iv) As to utility charges referred to in Section 4.4(a)(iii) hereof,
     Seller may on notice to Purchaser elect to pay one or more of all of said
     items accrued to the date hereinabove fixed for apportionment directly to
     the person or entity entitled thereto prior to the Closing, and to the
     extent Seller so elects, such item shall not be apportioned hereunder;

          (v) Purchaser shall be responsible for the payment of (A) all Tenant
     Inducement Costs (as hereinafter defined) and leasing commissions which
     become due and payable (whether before or after Closing) as a result of any
     new Leases, or any renewals, amendments or expansions of existing Leases,
     signed during the Lease Approval Period (as hereinafter defined) and, if
     required, approved or deemed approved in accordance with Section 5.4
     hereof; and (B) all Tenant Inducement Costs and leasing commissions with
     respect to new Leases, or renewals, amendments or expansions of existing
     Leases, signed or entered into from and after the date of Closing; and (C)
     all Tenant Inducement Costs and leasing commissions listed on Exhibit N
     attached hereto. If, as of the date of Closing, Seller shall have paid any
     Tenant Inducement Costs or leasing commissions for which Purchaser is
     responsible pursuant to the foregoing provisions, Purchaser shall reimburse
     Seller therefor at Closing. For purposes hereof, the term "Tenant
     Inducement Costs" shall mean any out-of-pocket payments required under a
     Lease to be paid by the landlord thereunder to or for the benefit of the
     tenant thereunder which is in the nature of a tenant inducement, including
     specifically, without limitation, tenant improvement costs, lease buyout
     costs, and moving, design, refurbishment and club membership allowances.
     The term "Tenant Inducement Costs" shall not include loss of income
     resulting from any free rental period, it being agreed that Seller shall
     bear the

                                       12

<PAGE>



     loss resulting from any free rental period until the date of Closing and
     that Purchaser shall bear such loss from and after the date of Closing. For
     purposes hereof, the term "Lease Approval Period" shall mean the period
     from the Effective Date until the date of Closing;

          (vi) Unpaid and delinquent Rent collected by Seller and Purchaser
     after the date of Closing shall be delivered as follows: (a) if Seller
     collects any unpaid or delinquent Rent for the Property, Seller shall,
     within fifteen (15) days after the receipt thereof, deliver to Purchaser
     any such Rent which Purchaser is entitled to hereunder relating to the date
     of Closing and any period thereafter, and (b) if Purchaser collects any
     unpaid or delinquent Rent from the Property, Purchaser shall, within
     fifteen (15) days after the receipt thereof, deliver to Seller any such
     Rent which Seller is entitled to hereunder relating to the period prior to
     the date of Closing. Seller and Purchaser agree, on a tenant-by-tenant
     basis, that (i) all Rent received by Seller or Purchaser within the first
     ninety (90) day period after the date of Closing from a tenant of the
     Property shall be applied first to delinquent Rent, if any, owed by said
     tenant, in the order of their maturity, and then to current Rent owed by
     said tenant, and (ii) all Rent received by Seller or Purchaser after the
     first ninety (90) day period after the date of Closing shall be applied
     first to current Rent owed by said tenant and then to delinquent Rent, if
     any, owed by said tenant, in the inverse order of maturity. Purchaser will
     make a good faith effort after Closing to collect all Rents in the usual
     course of Purchaser's operation of the Property, but Purchaser will not be
     obligated to institute any lawsuit or other collection procedures to
     collect delinquent Rents. Seller may attempt to collect any delinquent
     Rents owed Seller and may institute any lawsuit or collection procedures,
     but may not evict any tenant. In the event that there shall be any Rents or
     other charges under any Leases which, although relating to a period prior
     to Closing, do not become due and payable until after Closing or are paid
     prior to Closing but are subject to adjustment after Closing (such as year
     end common area expense reimbursements and the like), then any Rents or
     charges of such type received by Purchaser or its agents or Seller or its
     agents subsequent to Closing shall, to the extent applicable to a period
     extending through the Closing, be prorated between Seller and Purchaser as
     of Closing and Seller's portion thereof shall be remitted promptly to
     Seller by Purchaser. Notwithstanding anything contained in this Agreement
     to the contrary, Seller shall be entitled to all unpaid or delinquent Rent
     for the period prior to the Closing that is received by Seller or Purchaser
     from Goldman & Goldman in connection with that certain Agreement, dated as
     of February 15, 1995, a copy of which is attached hereto as Exhibit O-1,
     and that certain Stipulation of Settlement, dated September 5, 1995, a copy
     of which is attached hereto as Exhibit O-2.

     (c) Seller has filed and may continue to prosecute an appeal of the real
property tax assessment for the 1996/1997 tax years (and prior years), and may
take related action which Seller deems appropriate in connection therewith.
Purchaser shall cooperate

                                       13

<PAGE>



with Seller in connection with such appeal and collection of a refund of real
property taxes paid. Seller owns and holds all right, title and interest in and
to such appeal and refund, and all amounts payable in connection therewith shall
be paid directly to Seller by the applicable authorities. If such refund or any
part thereof is received by Purchaser, Purchaser shall promptly pay such amount
to Seller. Any refund received by Seller shall be distributed as follows: first,
to reimburse Seller for all costs incurred in connection with the appeal;
second, with respect to refunds payable to tenants of the Real Property pursuant
to the Leases, to such tenants in accordance with the terms of such Leases; and
third, to Seller to the extent such appeal covers the period prior to the
Closing, and to Purchaser to the extent such appeal covers the period as of the
Closing and thereafter. If and to the extent any such appeal covers the period
after the Closing, Purchaser shall have the right to participate in such appeal.

     (d) Except as otherwise provided herein, any revenue or expense amount
which cannot be ascertained with certainty as of Closing shall be prorated on
the basis of the parties' reasonable estimates of such amount, and shall be the
subject of a final proration within one hundred eighty (180) days after Closing,
or as soon thereafter as the precise amounts can be ascertained. Purchaser shall
promptly notify Seller when it becomes aware that any such estimated amount has
been ascertained. Once all revenue and expense amounts have been ascertained,
Purchaser shall prepare, and certify as correct, a final proration statement
which shall be subject to Seller's approval. Upon Seller's acceptance and
approval of any final proration statement submitted by Purchaser, such statement
shall be conclusively deemed to be accurate and final.

     (e) Subject to the final sentence of Section 4.4(d) hereof, the provisions
of this Section 4.4 shall survive Closing.

     Section 4.5 Transaction Taxes and Closing Costs.

     (a) Seller and Purchaser shall execute such returns, questionnaires and
other documents as shall be required with regard to all applicable real property
transaction taxes imposed by applicable federal, state or local law or
ordinance;

     (b) Seller shall pay the fees of any counsel representing Seller in
connection with this transaction. Seller shall also pay the following costs and
expenses:

          (i) any transfer tax, sales tax, documentary stamp tax or similar tax
     which becomes payable by reason of the transfer of the Property; and

          (ii) the fees for the Broker (as hereinafter defined in Section 8.1
     hereof).

connection with this transaction. Purchaser shall also pay the following costs

          (i) the fee for the title examination and any title commitments
     obtained by Purchaser and the premium for the Title Policy to be issued to
     Purchaser by the Title Company at Closing, and all endorsements thereto;

          (ii) the cost of any surveys obtained by Purchaser; and

          (iii) the fees for recording the Deed.

     (d) The Personal Property is included in this sale without charge, except
that Purchaser shall pay to Seller the amount of any and all sales or similar
taxes payable in connection with the transfer of the Personal Property and
Purchaser shall execute and deliver any tax returns required of it in connection
therewith;

     (e) All costs and expenses incident to this transaction and the closing
thereof, and not specifically described above, shall be paid by the party
incurring same; and

     (f) The provisions of this Section 4.5 shall survive the Closing.

     Section 4.6 Conditions Precedent to Obligation of Purchaser. The obligation
of Purchaser to consummate the transaction hereunder shall be subject to the
fulfillment on or before the date of Closing of all of the following conditions,
any or all of which may be waived by Purchaser in its sole discretion:

                                    ARTICLE V
                    REPRESENTATIONS, WARRANTIES AND COVENANTS

     Section 5.1 Representations and Warranties of Seller. Seller hereby makes
the following representations and warranties to Purchaser as of the Effective
Date, which representations and warranties shall be deemed to have been made
again as of the Closing, subject to Section 4.2(f) hereof:

     (a) Organization and Authority. Seller has been duly organized and is
validly existing under the laws of the State of New York. Seller has the full
right and authority to enter into this Agreement and to transfer all of the
Property and to consummate or cause to be consummated the transaction
contemplated by this Agreement. The person signing this Agreement on behalf of
Seller is authorized to do so.

     (b) Pending or Threatened Actions. To Seller's knowledge, Seller has not
received written notice of any action, suit, arbitration, unsatisfied order or
judgment, government investigation or proceeding pending or threatened against
Seller which, if adversely determined, could individually or in the aggregate
materially interfere with the consummation of the transaction contemplated by
this Agreement.

     (c) Operating Agreements. To Seller's knowledge, the Operating Agreements
listed on Exhibit C are all of the agreements concerning the operation and
maintenance of the Property entered into by Seller and affecting the Property,
except those operating agreements that are not assignable or are to be
terminated by Seller within thirty (30) days after the Closing, and except any
agreement with Seller's property manager, which shall be terminated by Seller.

     (d) Condemnation. To Seller's knowledge, Seller has received no written
notice of any condemnation proceedings relating to the Property.

                                       16

<PAGE>




     (e) Leases. To Seller's knowledge, the rent roll attached hereto as Exhibit
P is accurate in all material respects, and lists all of the leases currently
affecting the Property.

     (f) Litigation. To Seller's knowledge, except as set forth on Exhibit Q
attached hereto, and except tenant eviction proceedings, tenant bankruptcies,
and proceedings for the collection of delinquent rentals from tenants listed on
Exhibit Q-1 attached hereto, and except for proceedings related to claims for
personal injury or damage to property due to events occurring at the Property,
Seller has not received written notice of any litigation which has been filed
against Seller that arises out of the ownership of the Property and would
materially affect the Property or use thereof, or Seller's ability to perform
hereunder. To Seller's knowledge, in the event that there are any proceedings
related to claims for personal injury or damage to property due to events
occurring at the Property during the period of Seller's ownership of the
Property, such proceedings would be defended and satisfied by Seller's insurer.

     (g) Violations. To Seller's knowledge, except as set forth on Exhibit R
attached hereto, Seller has not received written notice of any violation of any
federal, state or local law relating to the use or operation of the Property
which would materially adversely affect the Property or use thereof and which
has not been cured prior to the Effective Date.

     Section 5.2 Knowledge Defined. References to the "knowledge" of Seller
shall refer only to the current actual knowledge of the Designated Employee (as
hereinafter defined in this Section 5.2) of Seller (after due inquiry of
Seller's property manager), and shall not be construed, by imputation or
otherwise, to refer to the knowledge of Seller or any affiliate of Seller, to
any property manager (except as otherwise set forth in this Section 5.2), or to
any other officer, agent, manager, representative or employee of Seller or any
affiliate thereof, or to impose upon such Designated Employee any duty to
investigate the matter to which such actual knowledge, or the absence thereof,
pertains (except as otherwise set forth in this Section 5.2). As used herein,
the term "Designated Employee" shall refer to Mr. John Kropke, Senior Investment
Analyst, Real Estate Investments Department, of Seller.

     Section 5.3 Survival of Seller's Representations and Warranties. The
representations and warranties of Seller set forth in Section 5.1 hereof as
updated as of the Closing in accordance with the terms of this Agreement, shall
survive Closing for a period of one hundred eighty (180) days. No claim for a
breach of any representation or warranty of Seller shall be actionable or
payable if the breach in question results from or is based on a condition, state
of facts or other matter which was known to Purchaser prior to Closing. Seller
shall have no liability to Purchaser for a breach of any representation or
warranty (a) unless the valid claims for all such breaches collectively
aggregate more than Two Hundred Thousand Dollars ($200,000.00), in which event
the full amount of such valid claims shall be actionable, up to the Cap

                                       17

<PAGE>



(as defined in this Section), and (b) unless written notice containing a
description of the specific nature of such breach shall have been given by
Purchaser to Seller prior to the expiration of said one hundred eighty (180) day
period and an action shall have been commenced by Purchaser against Seller
within two hundred forty (240) days of Closing. Seller shall not be liable to
Purchaser if Purchaser's claim is satisfied from any insurance policies, service
contracts or Leases; provided, however, Purchaser shall not be required to
exhaust such other potential sources of remedies prior to seeking recovery from
Seller. As used herein, the term "Cap" shall mean the total aggregate amount of
Two Million and 00/100 Dollars ($2,000,000.00).

     Section 5.4 Covenants of Seller. Seller hereby covenants with Purchaser as
follows:

     (a) From the Effective Date hereof until the Closing or earlier termination
of this Agreement, Seller shall use reasonable efforts to operate and maintain
the Property in a manner generally consistent with the manner in which Seller
has operated and maintained the Property prior to the date hereof, including the
maintenance of full replacement insurance for the Property (less the value of
the Land); and

     (b) Except as provided hereinbelow, a copy of any amendment, renewal or
expansion of an existing Lease (unless such renewal or expansion is pursuant to
the terms of an existing Lease) or of any new Lease which Seller wishes to
execute between the Effective Date and the date of Closing will be submitted to
Purchaser prior to execution by Seller. Purchaser agrees to notify Seller in
writing within five (5) business days after its receipt thereof of either its
approval or disapproval thereof, including all Tenant Inducement Costs and
leasing commissions to be incurred in connection therewith. In the event
Purchaser informs Seller within such five (5) business day period that Purchaser
does not approve the amendment, renewal or expansion of the existing Lease or
the new Lease, which approval shall not be unreasonably withheld, Seller shall
have the right to terminate this Agreement by written notice thereof to
Purchaser within five (5) business days after Seller's receipt of written notice
of Purchaser's disapproval thereof. If this Agreement is not terminated pursuant
to the foregoing provisions of this paragraph, then Seller shall not proceed
with such amendment, renewal or expansion of the existing Lease or the new
Lease. If this Agreement is terminated pursuant to the foregoing provisions of
this paragraph, then neither party shall have any further rights or obligations
hereunder (except for any indemnity obligations of either party pursuant to the
other provisions of this Agreement other than the obligations set forth in
Article 11 hereof, which shall void and thereupon of no force or effect), the
Deposit shall be returned to Purchaser and each party shall bear its own costs
incurred hereunder. In the event Purchaser fails to notify Seller in writing of
its approval or disapproval within the five (5) business day period set forth
above, Purchaser shall be deemed to have approved such new Lease, amendment,
renewal or expansion. At Closing, Purchaser shall

                                       18

<PAGE>



reimburse Seller for any Tenant Inducement Costs, leasing commissions or other
expenses, including legal fees, paid by Seller pursuant to an amendment, a
renewal, an expansion or a new Lease approved (or deemed approved) by Purchaser.

     Section 5.5 Representations and Warranties of Purchaser. Purchaser hereby
makes the following representations and warranties to Seller as of the Effective
Date, which representations and warranties shall be deemed to have been made
again as of the Closing, subject to Section 4.3(c) hereof:

     (a) Organization and Authority. Purchaser has been duly organized and is
validly existing under the laws of the State of Delaware. Purchaser has the full
right and authority to enter into this Agreement and to consummate or cause to
be consummated the transaction contemplated by this Agreement. The person
signing this Agreement on behalf of Purchaser is authorized to do so;

     (b) Pending Actions. To Purchaser's knowledge, there is no action, suit,
arbitration, unsatisfied order or judgment, government investigation or
proceeding pending against Purchaser which, if adversely determined, could
individually or in the aggregate materially interfere with the consummation of
the transaction contemplated by this Agreement.

     (c) ERISA. As of the Closing, (1) Purchaser will not be an employee benefit
plan as defined in Section 3(3) of the Employee Retirement Income Security Act
of 1974, as amended ("ERISA"), which is subject to Title I of ERISA, nor a plan
as defined in Section 4975(e)(1) of the Internal Revenue Code of 1986, as
amended (each of the foregoing hereinafter referred to collectively as "Plan"),
and (2) the assets of the Purchaser will not constitute "plan assets" of one or
more such Plans within the meaning of Department of Labor ("DOL") Regulation
Section 2510.3-101.

     As of the Closing, if Purchaser is a "governmental plan" as defined in
Section 3(32) of ERISA, the closing of the sale of the Property will not
constitute or result in a violation of state or local statutes regulating
investments of and fiduciary obligations with respect to governmental plans.

     As of the Closing, Purchaser will be acting on its own behalf and not on
account of or for the benefit of any Plan.

     Purchaser has no present intent to transfer the Property to any entity,
person or Plan which will cause a violation of ERISA.

     Purchaser shall not assign its interest under this Agreement to any entity,
person, or Plan which will cause a violation of ERISA.

     Section 5.6 Survival of Purchaser's Representations and Warranties. The
representations and warranties of Purchaser set forth in Section 5.5 hereof as
updated as of the Closing in accordance with the terms of this Agreement, shall
survive Closing

                                       19

<PAGE>



for a period of one hundred eighty (180) days. Purchaser shall have no liability
to Seller for a breach of any representation or warranty unless written notice
containing a description of the specific nature of such breach shall have been
given by Seller to Purchaser prior to the expiration of said one hundred eighty
(180) day period and an action shall have been commenced by Seller against
Purchaser within two hundred forty (240) days of Closing.

                                   ARTICLE VI
                                     DEFAULT

     Section 6.1 Default by Purchaser. In the event the sale of the Property as
contemplated hereunder is not consummated due to Purchaser's default hereunder,
Seller shall be entitled, as its sole remedy, to terminate this Agreement and
receive the Deposit as liquidated damages for the breach of this Agreement, it
being agreed between the parties hereto that the actual damages to Seller in the
event of such breach are impractical to ascertain and the amount of the Deposit
is a reasonable estimate thereof.

     Section 6.2 Default by Seller. In the event the sale of the Property as
contemplated hereunder is not consummated due to Seller's default hereunder,
Purchaser shall be entitled, as its sole remedy, either (a) to receive the
return of the Deposit, which return shall operate to terminate this Agreement
(except for any indemnity obligations of either party pursuant to the other
provisions of this Agreement other than the obligations set forth in Article 11
hereof, which shall be void and thereupon of no force or effect) and release
Seller from any and all liability hereunder, except as otherwise expressly
provided in this clause (a), or (b) to enforce specific performance of Seller's
obligation to convey the Property to Purchaser in accordance with the terms of
this Agreement, it being understood and agreed that the remedy of specific
performance shall not be available to enforce any other obligation of Seller
hereunder. Purchaser expressly waives its rights to seek damages in the event of
Seller's default hereunder. Purchaser shall be deemed to have elected to
terminate this Agreement and receive back the Deposit if Purchaser fails to file
suit for specific performance against Seller in a court having jurisdiction in
the county and state in which the Property is located, on or before sixty (60)
days following the date upon which Closing was to have occurred.

     Section 6.3 Recoverable Damages. Notwithstanding Sections 6.1 and 6.2
hereof, in no event shall the provisions of Sections 6.1 and 6.2 limit the
damages recoverable by either party against the other party due to the other
party's obligation to indemnify such party in accordance with this Agreement.

                                   ARTICLE VII
                                  RISK OF LOSS

     Section 7.1 Minor Damage. In the event of loss or damage to the Property or
any portion thereof which is not "Major" (as hereinafter defined), this
Agreement shall remain in full force and

                                       20

<PAGE>



effect provided that Seller shall, at Seller's option, either (a) perform any
necessary repairs, or (b) assign to Purchaser, without representation, warranty
or recourse to Seller, all of Seller's right, title and interest in and to any
claims and proceeds Seller may have with respect to any net casualty insurance
policies or net condemnation awards relating to the premises in question (that
is, after expense of collection), subject however, to Seller's right to receive
reimbursement therefrom of any amounts paid or incurred by Seller for or on
account of any amounts paid or incurred by Seller for or on account of repairs
and/or restoration of the Property prior to Closing. In the event that Seller
elects to perform repairs upon the Property, Seller shall use reasonable efforts
to complete such repairs promptly and the date of Closing shall be extended a
reasonable time in order to allow for the completion of such repairs. If Seller
elects to assign a casualty claim to Purchaser, the Purchase Price shall be
reduced by an amount equal to the lesser of the deductible amount under Seller's
insurance policy or the cost of such repairs as determined in accordance with
Section 7.3 hereof. Upon Closing, full risk of loss with respect to the Property
shall pass to Purchaser.

     Section 7.2 Major Damage. In the event of a "Major" loss or damage, either
Seller or Purchaser may terminate this Agreement by written notice to the other
party, in which event the Deposit shall be returned to Purchaser. If neither
Seller nor Purchaser elects to terminate this Agreement within ten (10) days
after Seller sends Purchaser written notice of the occurrence of such Major loss
or damage (which notice shall state the cost of repair or restoration thereof as
opined by an architect in accordance with Section 7.3 hereof), then Seller and
Purchaser shall be deemed to have elected to proceed with Closing, in which
event Seller shall, at Seller's option, either (a) perform any necessary
repairs, or (b) assign to Purchaser, without representation, warranty or
recourse to Seller, all of Seller's right, title and interest in and to any
claims and proceeds Seller may have with respect to any net casualty insurance
policies or net condemnation awards relating to the premises in question (that
is, after expense of collection), subject however, to Seller's right to receive
reimbursement therefrom of any amounts paid or incurred by Seller for or on
account of any amounts paid or incurred by Seller for or on account of repairs
and/or restoration of the Property prior to Closing. In the event that Seller
elects to perform repairs upon the Property, Seller shall use reasonable efforts
to complete such repairs promptly and the date of Closing shall be extended a
reasonable time in order to allow for the completion of such repairs. If Seller
elects to assign a casualty claim to Purchaser, the Purchase Price shall be
reduced by an amount equal to the lesser of the deductible amount under Seller's
insurance policy or the cost of such repairs as determined in accordance with
Section 7.3 hereof. Upon Closing, full risk of loss with respect to the Property
shall pass to Purchaser.

     Section 7.3 Definition of "Major" Loss or Damage. For purposes of Sections
7.1 and 7.2, "Major" loss or damage refers to the following: (a) loss or damage
to the Property hereof such that the cost of repairing or restoring the premises
in question to

                                       21

substantially the same condition which existed prior to the event of damage
would be, in the opinion of an architect selected by Seller and reasonably
approved by Purchaser, equal to or greater than Two Million and 00/100 Dollars
($2,000,000.00), and (b) any loss due to a condemnation which permanently and
materially impairs the current use of the Property. If Purchaser does not give
written notice to Seller of Purchaser's reasons for disapproving an architect
within five (5) business days after receipt of notice of the proposed architect,
Purchaser shall be deemed to have approved the architect selected by Seller.

     Section 7.4 Section 5-1311 of the New York General Obligations Law. The
terms of this Article VII shall be deemed to be the terms of an agreement which
"expressly provides otherwise" within the meaning of Section 5-1311 of the New
York General Obligations Law.

person or entity, other than the Broker, makes a claim for brokerage commissions

such claim is made by, through or on account of any acts or alleged acts of said
party or its representatives, said party will protect, indemnify, defend and
hold the other party free and harmless from and against any and all loss,
liability, cost, damage and expense (including reasonable attorneys' fees) in
connection therewith. The provisions of this paragraph shall survive Closing or

     Section 9.3 Survival of Disclaimers. The provisions of this Article IX
shall survive Closing or any termination of this Agreement.

                                    ARTICLE X
                                  MISCELLANEOUS

     Section 10.1 Confidentiality. Purchaser and its representatives shall hold
in strictest confidence all data and information obtained with respect to Seller
or its business, whether obtained before or after the execution and delivery of
this Agreement, and shall not disclose the same to others; provided, however,
that it is understood and agreed that Purchaser may disclose such data and
information to the employees, lenders, consultants, accountants and attorneys of
Purchaser provided that such persons agree in writing to treat such data and
information confidentially. In the event this Agreement is terminated or
Purchaser fails to perform hereunder, Purchaser shall promptly return to Seller
any statements, documents, schedules, exhibits or other written information
obtained from Seller in connection with this Agreement or the transaction
contemplated herein. It is understood and agreed that, with respect to any
provision of this Agreement which refers to the termination of this Agreement
and the return of the Deposit to Purchaser, such Deposit shall not be returned
to Purchaser unless and until Purchaser has fulfilled its obligation to return
to Seller the materials described in the preceding sentence. In the event of a
breach or threatened breach by Purchaser or its agents or representatives of
this Section 10.1, Seller shall be entitled to an injunction restraining
Purchaser or its agents or representatives from disclosing, in whole or in part,
such confidential information. Nothing herein shall be construed as prohibiting
Seller from pursuing any other available remedy at law or in equity for such
breach or threatened breach. The provisions of this Section 10.1 shall survive
Closing or any termination of this Agreement.

     Section 10.2 Public Disclosure. Prior to and after the Closing, no press
release or other public disclosure (except to the extent required by law,
including any filings required by the Securities and Exchange Commission and
communications with each of the limited partners of Purchaser) regarding the
purchase and sale as contemplated hereby will be issued or made by either party
without the prior written consent of both parties. The provisions of this
Section 10.2 shall survive the Closing or any termination of this Agreement.

     Section 10.3 Assignment. Subject to the provisions of this Section 10.3,
the terms and provisions of this Agreement are to apply to and bind the
permitted successors and assigns of the parties hereto. Purchaser may not assign
its rights under this Agreement without first obtaining Seller's written
approval, which

                                       25

<PAGE>



approval may be given or withheld in Seller's sole discretion. Notwithstanding
the preceding sentence, so long as Purchaser satisfies all of the conditions of
this Section 10.3, the prior written approval of Seller shall not be required in
the event that Purchaser assigns its rights under this Agreement to any entity
controlled by Purchaser. For purposes of this Section 10.3, the phrase "control"
shall mean the ownership of sufficient equity or voting interests of a
corporation or similar entity to enable the holder thereof to elect a majority
of the directors (or persons performing similar functions) thereof and in the
case of a partnership or joint venture, the ownership of more than a 50%
interest in the profits or capital thereof. In the event Purchaser intends to
assign its rights hereunder, (a) Purchaser shall send Seller written notice
thereof at least ten (10) business days prior to Closing, which notice shall
include the legal name and structure of the proposed assignee, as well as any
other information that Seller may reasonably request, and (b) Purchaser and the
proposed assignee shall execute an assignment and assumption of this Agreement
in form and substance satisfactory to Seller, and (c) in no event shall any
assignment of this Agreement release or discharge Purchaser from any liability
or obligation hereunder. Any assignee permitted under this Section 10.3 shall
make and deliver in writing to Seller the same representations at Closing as are
made by Purchaser in this Agreement. Notwithstanding the foregoing, under no
circumstances shall Purchaser have the right to assign this Agreement to any
person or entity owned or controlled by an employee benefit plan if Seller's
sale of the Property to such person or entity would, in the reasonable opinion
of Seller's ERISA advisor, create or otherwise cause a "prohibited transaction"
under ERISA. Any transfer, directly or indirectly, of any stock, partnership
interest or other ownership interest in Purchaser shall constitute an assignment
of this Agreement. The provisions of this Section 10.3 shall survive the Closing
or any termination of this Agreement.

     Section 10.4 Notices. Any notice pursuant to this Agreement shall be given
in writing by (a) personal delivery, (b) reputable overnight delivery service
with proof of delivery, (c) United States Mail, postage prepaid, registered or
certified mail, return receipt requested, or (d) legible facsimile transmission,
sent to the intended addressee at the address set forth below, or to such other
address or to the attention of such other person as the addressee shall have
designated by written notice sent in accordance herewith, and shall be deemed to
have been given upon receipt or refusal to accept delivery, or, in the case of
facsimile transmission, as of the date of the facsimile transmission provided
that an original of such facsimile is also sent to the intended addressee by
means described in clauses (a), (b) or (c) above. Unless changed in accordance
with the preceding sentence, the addresses for notices given pursuant to this
Agreement shall be as follows:

     3.1 Title Report; Survey.

     Purchaser acknowledges and agrees that Seller has furnished to Purchaser

     (a)  A preliminary title report (the "Title Report"), issued by Chicago
          Title Insurance Company ("Title Company") covering the Real Property
          and Improvements, with such Title Report setting forth the status of
          the title to the Property and showing all liens, claims, encumbrances,
          easements, rights-of-way, encroachments, reservations, restrictions
          and any other matters of record affecting the Property.

     (b)  A copy of all recorded documents referred to in the Title Report as
          exceptions to title to the Property (the "Title Documents").

     3.2  Review of Title.

     Purchaser shall have until February 21, 1997 (the "Title Approval Date") to
review the Title Report, Title Documents and Survey (collectively, "Title
Evidence") and render any objections as to matters of title i


                                      -4-
<PAGE>

writing to Seller. Any such matters of title not timely objected to by Purchaser
shall be deemed waived and Purchaser shall be deemed to agree to acquire the
Property subject to such exceptions (collectively, "Permitted Exceptions")
hereunder. Seller, in its sole and absolute discretion, may elect to remove or
satisfy any such objections, provided that Seller shall have until February 26,
1997 to have such objections that Seller so elects removed or satisfied. Subject
to Purchaser's reasonable approval, Seller may cause the Title Company to issue
a title endorsement or "insure over" any objection (each, a "Seller
Endorsement") and it shall have the same effect as if such objection was cured
by Seller. If Seller shall fail to have such objections removed, insured over or
satisfied within such time or during such time delivers a written notice to
Purchaser that notwithstanding Seller's reasonable efforts, such objections may
not be cured, then, in the absence of a default by Purchaser, Purchaser may, by
written notice to Seller prior to Closing, either (a) terminate this Agreement
without any liability on its part, in which case the Deposit together with
interest thereon shall be refunded to Purchaser and neither party shall have any
further rights or obligations hereunder (except as set forth in Sections 3.6(b),
9.1, 11.2 and 11.12 hereof) or (b) proceed to Closing and take title subject to
such objections, in which case such non-cured objections shall become Permitted
Exceptions hereunder. After the Title Approval Date but prior to the Closing
Date, Purchaser shall also have the right to disapprove in writing any
additional item not previously set forth in the Title Report that Title Company
intends to show as an exception to title in the Title Policy. Any such
additional item not specifically disapproved in writing delivered within two (2)
days following Purchaser's receipt of written notice of such additional item
shall be deemed approved. Seller shall have until Closing to remove or cause
Title Company to insure over any disapproved item at Seller's own expense.
Seller may elect to (a) extend the Closing until the day after the date upon
which Seller is able to remove or cause Title Company to insure over any such
disapproved item (but in no event shall such extension exceed ten (10) business
days after the Closing Date), or (b) terminate this Agreement, in which event
neither Seller nor Purchaser shall have any further obligation hereunder (except
as set forth under Sections 3.6(b), 9.1, 11.2 and 11.12 hereof), Purchaser shall
return all documents to Seller and the Deposit and any interest accrued thereon
shall be returned to Purchaser. Notwithstanding anything in


                                      -5-
<PAGE>

given by Purchaser hereunder, Seller shall cause all mortgages and deeds of
trust encumbering Seller's interest in the Real Property, and all mechanic's
liens filed against the Property relating to work performed on the Property and
contracted for by Seller, to be released and reconveyed from the Real Property,
or, with respect to such mechanic's liens, otherwise bonded, on or prior to the
Closing and shall cause the Title Company to insure title to the Real Property
as vested in Purchaser without any exception for such matters.


     3.3  Vesting of Title.

     At Closing, Seller shall convey all of Seller's right, title and interest
in and to the Real Property and Improvements to Purchaser by standard grant deed
(as further described in Section 4.2(a)(i) below), subject to the Permitted
Exceptions, and shall convey Seller's interest in the Personal Property to
Purchaser by bill of sale (as further described in Section 4.2(a)(ii) below).

     3.4  Title Insurance.

     At Closing, the Title Company shall issue to Purchaser an ALTA extended
coverage Owner's Policy of Title Insurance (Form B, rev. 10/17/70 with
Endorsement Form 1 coverage), in the amount of the Purchase Price insuring that
title to the Real Property and Improvements is vested in Purchaser subject to
the Permitted Exceptions (the "Title Policy"), provided that, if required by the
Title Company, Purchaser at its sole cost and expense shall update the existing
survey of the Property and deliver a copy of same certified to the Title Company
in a manner that will allow the Title Company to issue the extended coverage
title policy.

     3.5  Inspection Period.

     Purchaser shall have until February 21, 1997 (the "Inspection Period") to
inspect the Property, the Due Diligence Documents (as hereinafter defined in
Section 3.6(c)), and perform such other due diligence with respect to the
Property as Purchaser reasonably deems necessary, subject to the rights of
tenants in possession of the Property. In the absence of a default by Purchaser,
Purchaser may, upon written notice to Seller, received by Seller no later than

terminate this Agreement. Upon any such termination, the Deposit together with
interest thereon shall be refunded to Purchaser and, subject to Sections 3.6(b),
9.1, 11.2 and 11.12 hereof, neither party shall have any further rights or
obligations hereunder. In the event no notice of termination is received by
Seller on or before such time, then the Deposit, together with all accrued
interest thereon, shall become non-refundable (subject to the other terms and
conditions of this Agreement) and Seller and Purchaser shall proceed to Closing
in accordance with the terms and conditions hereof and the Inspection Period
termination rights shall be deemed waived by Purchaser. Purchaser shall not
undertake any soil borings, ground water testing or other "Phase 2"
investigative procedures without first having obtained the prior written consent
of Seller. In connection with Purchaser's inspection of the Property, Purchaser
agrees that:

     (a)  All inspection fees, engineering fees, or other expenses of any kind
          incurred by Purchaser relating to the inspection of the Property will
          be at Purchaser's sole cost and expense;

     (b)  Purchaser will give Seller reasonable advance notice of the dates of
          all inspections and will schedule all tests and inspections during
          normal business hours whenever feasible unless otherwise requested by
          Seller;

     (c)  Seller will have the right to have one or more representatives of
          Seller accompany Purchaser and Purchaser's representatives, agents or
          designees while they are on the Property;

     (d)  Any entry by Purchaser, its representatives, agents or designees will
          not unreasonably interfere with Seller's use of the Property or with
          the operations of any tenant;

     (e)  Purchaser will restore any damage caused to the Property by
          Purchaser's entry on the Property for inspection purposes at
          Purchaser's sole cost and expense if this transaction does not close;
          and

<PAGE>

     (f)  In making any inspection hereunder, Purchaser will treat and will
          cause any representative of Purchaser to treat all information
          obtained by Purchaser pursuant to the terms of this Agreement as
          strictly confidential in accordance with Section 11.12 below.

Purchaser shall have the right to further inspect the Property within the two
(2) business day period immediately preceding the Closing (during normal
business hours and upon notice to Seller) for the purpose of confirming that the
Property is in the same condition at Closing as existing at the end of the
Inspection Period, reasonable wear and tear excepted; provided, however, that
such right of pre-closing inspection shall in no way be deemed to extend or
resurrect the Inspection Period or constitute a condition to Closing, subject
however, to the other terms and conditions of this Agreement. For purposes of
this Agreement, the term "business day" shall mean a day other than any
Saturday, Sunday, or day upon which national banks in the City of Woodland,
California are not open for general banking business.

     The covenants of Purchaser contained in this Section 3.5(a) and (e) shall
survive the Closing Date or any earlier termination of this Agreement.

          Lease. Purchaser hereby indemnifies, defends and holds Seller and the
          Property harmless from any and all costs, loss, damages or expenses,
          of any kind or nature (including, without limitation, mechanics' liens
          and including, without limitation, reasonable attorneys' fees and
          expenses) arising out of or resulting from such inspection,
          investigation, entry and/or other activities upon the Property by
          Purchaser, its employees, agents, contractors, subcontractors, and/or
          assigns. Notwithstanding anything to the contrary herein, the
          indemnity set forth in this Section 3.6(b) shall survive (i) any
          termination of this Agreement, and (ii) the Closing and not be merged
          therein.

          (2) years and copies of such historical information in Seller's
          possession or the possession of Seller's agents regarding operating
          expenses of the Property as Purchaser shall reasonably request; (iii)
          the documents listed in 3.6(a) above; and (iv) guaranties, warranties,

          governmental permits (including Certificates of Occupancy) and
          relevant, pertinent reports and agreements in the possession of Seller
          or its agents pertaining to the Property, if any (i.e., engineering
          reports, environmental reports, and as-built plans) and service
          contracts relating to the Property (collectively, the "Due Diligence
          Documents"), on site at the Property or at the business office of
          Seller or otherwise. Seller shall reasonably cooperate with Purchaser
          to obtain any consents required in connection with an assignment of
          any of the Due Diligence Documents. All of the Due Diligence Documents
          are confidential and shall not be distributed or disclosed by
          Purchaser to any person or entity not associated with Purchaser in
          accordance with Section 11.12 hereof. Seller agrees to deliver to
          Purchaser a copy of any written notices which Seller receives prior to
          Closing from any governmental authority pertaining to any violation of
          law or ordinance regulating the use of the Property which are received
          by Seller prior to the Closing Date and of any notice which Seller
          receives prior to Closing from any tenant regarding any default under
          any Lease. If the transaction fails to close for any reason
          whatsoever, Purchaser shall return to Seller all of the Due Diligence
          Documents which Seller or its agents may have delivered to Purchaser
          in accordance with this Section 3.6(b). THE FURNISHING OF ANY

          BE INTERPRETED IN ANY MANNER AS A REPRESENTATION OR WARRANTY OF ANY
          TYPE OR KIND BY SELLER, ANY PARTNER OF SELLER OR AGENT OF SELLER, OR
          ANY OFFICER, DIRECTOR, OR EMPLOYEE OF SELLER, OR ITS AGENTS, OR ANY
          OTHER PARTY RELATED IN ANY WAY TO ANY OF THE FOREGOING.

     3.7  Consideration. Notwithstanding anything in this Agreement to the
contrary, to induce Purchaser to enter into this Agreement and to expend the
time and resources necessary to evaluate the Property and possibly forego other
opportunities while doing so, Seller hereby grants to Purchaser the rights to

                                      -10-
<PAGE>

resources and possible loss of opportunity by Purchaser constitute adequate
consideration for Seller's remaining bound by this Agreement notwithstanding
such termination rights in Purchaser.

               the Closing Date and directing the Title Company to deposit or
               wire the same into Seller's designated account upon the
               recording by the Title Company of the documents to be executed

5. PRORATIONS; CLOSING ITEMS

     5.1  Prorations; Closing Costs.

     (a)  The amount due on any gas, electric, water, sewer, or other utility
          bill, or service contract relating to the Property shall be prorated
          between Seller and Purchaser as of the Closing Date, to the extent
          such utilities or service contracts are the obligation of the Seller
          and not a direct or indirect obligation of the tenants. Any utility
          deposits made by Seller shall be and remain the property of Seller.

     (b)  All collected rents and other payments from the tenant under the
          Lease, including, but not limited to, base rent, additional rent,
          percentage rent (if any), and expense reimbursements, shall be
          prorated between Seller and Purchaser as of the Closing Date. The
          balance remaining from any security deposits required under the Lease
          or prepaid rent held by Seller shall be 


                                      -16-
<PAGE>

          credited to Purchaser (including the balance of estimated tax,
          insurance and common area maintenance payments made to Seller by the
          tenant under the Lease net of any payments by Seller thereon).
          Purchaser agrees to indemnify and hold harmless Seller from and
          against any loss, cost or expense (including, but not limited to,
          attorneys' fees) resulting from any claim for such deposits or prepaid
          rent actually paid or credited to Purchaser. If any rent or other
          payments under the Lease are in arrears as of the Closing Date
          ("Delinquent Rents"), the amount of any such Delinquent Rents which
          are collected by Purchaser shall be promptly paid by Purchaser to
          Seller after Closing. Purchaser shall be entitled to deduct from any
          such payment (i) Purchaser's reasonable costs of collection incurred
          with respect to such tenant (including attorneys' fees), (ii) rents
          due for the month in which such payment is received by Purchaser, and
          (iii) rents from such tenant attributable to any period after the
          Closing that are past due on the date of receipt. Purchaser agrees to
          use commercially reasonable efforts to collect Delinquent Rents after
          the Closing provided Purchaser shall not be required to bring any
          action or proceeding against any tenant on account of Delinquent
          Rents. Purchaser's obligations hereunder with respect to the
          collection and payment of Delinquent Rents shall survive the Closing.
          Seller may make reasonable efforts to collect Delinquent Rents from
          and after the Closing Date; provided, however, that Seller shall not
          be entitled to pursue any action for eviction of any tenant from the
          Property. The provisions of this Section shall survive Closing and
          shall not be merged therein.

     (c)  All real estate taxes attributable to the Property for the fiscal year
          beginning July 1, 1996 and ending June 30, 1997 shall be prorated as
          of the Closing provided Seller shall be entitled to recover any
          reimbursements from the tenant on account of such taxes for the period
          prior to Closing, and Purchaser shall immediately


                                      -17-
<PAGE>

          remit to Seller any such reimbursements received by Purchaser upon
          receipt thereof. Any real estate taxes due and payable for any periods
          subsequent to the fiscal year ending June 30, 1997 shall be the
          obligation of Purchaser and any real estate taxes due and payable for
          any periods prior to the fiscal year beginning July 1, 1996 shall be
          the obligation of Seller, provided Purchaser shall cooperate with
          Seller to obtain any reimbursement from any tenant in respect of any
          such taxes. Seller and Purchaser agree to mutually cooperate with each
          other in connection with ongoing tax reduction proceedings relating to
          prior tax years, if any, and any ongoing or future proceedings
          relating to the fiscal year in which the Closing occurs, if any, and
          any refund resulting therefrom (to the extent not refundable to the
          tenant under the Lease) shall be prorated between Seller and Purchaser
          based on the Closing Date, after deducting therefrom the reasonable
          out-of-pocket expenses incurred by the parties. The provisions of the
          immediately preceding two sentences shall survive Closing and shall
          not be merged therein.

     (d)  Purchaser shall pay for the cost of recording the Deed, the cost of
          any Purchaser Endorsements or special or extended coverages of any
          nature in connection with the Title Policy and shall pay the
          difference in price between a standard coverage title policy and the
          extended coverage title policy being received, one-half (1/2) of any
          escrow fees and closing fees to the Title Company, any surveys or
          updates prepared by or at the direction of Purchaser, and any lender's
          title insurance coverage for any loan obtained by Purchaser. Purchaser
          shall pay for all costs relating to any financing obtained by
          Purchaser in connection with its purchase of the Property and all
          costs incurred by Purchaser in performing any related tests and
          investigations. Seller shall pay the base premium for the Title Policy
          equal to a standard coverage title policy and the Seller Endorsements
          (without the cost of any endorsements or special or


                                      -18-
<PAGE>

          extended coverages other than the Seller Endorsements), one-half (1/2)
          of all escrow fees and closing fees charged by the Title Company, any
          documentary transfer tax, any prepayment or reconveyance fee in
          connection with any payoff or release of any existing deed of trust or
          mortgage, and the recording fees with respect to documents which
          Seller elects to place of record in order to cure title objections
          raised by Purchaser to the extent Seller elects to cure the same, as
          fully described in said Section 3.2. Each party shall pay its own
          attorney's fees.

    5.2  Calculation of Prorations.

     For purposes of calculating prorations, Seller shall be deemed to be in
title to the Property, and therefore entitled to the income therefrom and
responsible for the expenses thereof, through the day prior to the Closing Date
and Purchaser shall be deemed to be in title to the Property, and therefore
entitled to the income therefrom and responsible for the expenses thereof, from
and after 12:01 a.m. on the Closing Date. All prorations shall be made on the
basis of the actual number of days of the year and month which have elapsed as
of the Closing Date. All prorations which cannot be ascertained as of the
Closing shall be prorated on the basis of the parties' reasonable estimate of
such amount. Except as otherwise stated above, if necessary, the amount of
prorations shall be adjusted in cash after Closing, as and when complete and
accurate information becomes available but in any event no later than one
hundred twenty (120) days after the Closing Date; provided, however, the one
hundred twenty (120) day period shall be extended for a reasonable time for any
real property tax reduction or abatement proceeds, which are to be prorated
between Purchaser and Seller pursuant to Section 5.1(c) and for any period of
time which may be required for reconciliation of tax, insurance, and common area
maintenance expenses for the calendar year in which the Closing Date occurs.
Purchaser and Seller each agree to reasonably cooperate with the other with
respect to such final proration. This provision shall survive Closing and shall
not be merged therein.

          knowledge of Seller.

     Except with respect to the warranties set forth in Section 6.1 hereof,

          real estate market in sufficient detail to fully satisfy itself with
          respect to the environmental conditions and the market conditions
          affecting the Property including, without limitation, property values,
          interest rates, and similar market factors. Purchaser has reached its
          conclusions based upon its own analysis and without relying upon
          representations by Seller, its employees, agents or consultants.

          6.3   Purchaser Accepts Property ("As Is").

          (a)  Purchaser Acknowledgment. As of the expiration of the Inspection

               Purchaser's choosing and (ii) that Purchaser is acquiring the
               Property based solely upon Purchaser's own investigation and

               6.1(a) THROUGH (l) HEREOF, PURCHASER FURTHER ACKNOWLEDGES AND
               AGREES THAT IT IS RELYING SOLELY UPON ITS OWN INSPECTION OF THE
               PROPERTY AND NOT UPON ANY REPRESENTATIONS MADE TO IT BY SELLER,
               ITS OFFICERS, DIRECTORS, CONTRACTORS, AGENTS OR EMPLOYEES OR ANY
               PERSON WHOMSOEVER. ANY REPORTS, REPAIRS OR WORK REQUIRED BY
               PURCHASER ARE TO BE THE SOLE RESPONSIBILITY OF PURCHASER AND
               PURCHASER AGREES THAT THERE IS NO OBLIGATION ON THE PART OF
               SELLER TO MAKE ANY CHANGES, ALTERATIONS, OR REPAIR TO THE
               PROPERTY AND PURCHASER ACKNOWLEDGES THAT, UPON EXPIRATION OF THE

               PURCHASER IS SOLELY RESPONSIBLE FOR OBTAINING ANY RESALE
               CERTIFICATE OR ANY OTHER APPROVAL OR PERMIT NECESSARY FOR
               TRANSFER OF THE PROPERTY AND FOR ANY REPAIRS OR ALTERATIONS

<PAGE>

               THE SAME, ALL AT PURCHASER'S SOLE COST AND EXPENSE.

          (b)  No Claim for Hazardous Materials. Upon Closing, Purchaser, for
               Purchaser and Purchaser's successors in interest, releases Seller
               from, and waives all claims and liability which Purchaser may
               have against Seller for, any structural, physical and
               environmental condition of the Property, including without
               limitation the presence, discovery or removal of any Hazardous
               Materials in, at, about or under the Property, or for, connected
               with or arising out of any and all claims or causes of action
               based upon the Comprehensive Environmental Response,
               Compensation, and Liability Act of 1980 ("CERCLA"), the Superfund
               Amendments and Reauthorization Act of 1986 ("SARA"), the Resource
               Conservation and Recovery Act ("RCRA"), the Toxic Substances
               Control Act (the "TSCA"), as such acts may be amended from time
               to time, or any other federal or state statutory or regulatory
               cause of action arising from or related to Hazardous Materials
               at, in or under the Property (collectively, the "Hazardous Waste
               Laws") The waiver and release of Purchaser set forth in this
               Section 6.3(b) shall survive the Closing Date and shall be
               enforceable at any time after the Closing Date.

          (c)  "Hazardous Materials" Defined. For purposes of this Agreement,
               the term "Hazardous Material" shall mean any substance, chemical,
               waste or material that is or becomes regulated by any federal,
               state or local governmental authority because of its toxicity,
               infectiousness, radioactivity, explosiveness, ignitability,
               corrosiveness or reactivity, including, without limitation, those
               substances regulated by the Hazardous Waste Laws.

          (d)  No Representations as to Hazardous Materials. Purchaser
               acknowledges that Seller has made no representations or
               warranties whatsoever to Purchaser regarding the presence or
               absence of any Hazardous Materials in, at, or under the 


                                      -26-
<PAGE>

               Property; provided, however, that Seller and Purchaser
               acknowledge that Seller has made certain representations as to no
               proceedings, notices received, or knowledge as more specifically
               set forth in Sections 6.1(d), (f) and (g) hereof. Purchaser has
               made such studies and investigations, conducted such tests and
               surveys, and engaged such specialists as Purchaser has deemed
               appropriate to evaluate fairly the Property, and its risks from
               an environmental and Hazardous Materials standpoint.

     In furtherance of the general release of all claims against Seller as set
forth in this Section 6.3, Purchaser expressly acknowledges that it is familiar
with California Civil Code Section 1542 which provides:

             "The general release does not extend to claims which the creditor
             does not know or suspect to exist in his favor at the time of
             executing the release, which if known by him must have materially
             affected his settlement with the debtor."

Purchaser expressly waives the benefits and protections of Section 1542. Each
covenant, agreement, representation, and warranty of Purchaser contained in this
Section 6.3 of this Agreement shall survive Closing or termination of this
Agreement. This provision is a material inducement for each of the parties to
enter into this transaction.

8. DAMAGE OR DESTRUCTION OF THE PROPERTY; CONDEMNATION

     8.1  Damage or Destruction of the Property.

     (a)  If, between the Effective Date and the Closing Date, the Property is
          Materially Damaged or Destroyed (as hereinafter defined), Purchaser
          may elect in writing, within five (5) days after receipt of notice by
          Purchaser from Seller of such damage or destruction, accompanied by
          information regarding the amount and payment of insurance (the
          "Casualty Notice Date"), to terminate this Agreement or to purchase
          all of the Property without regard to such damage or destruction. If
          Purchaser fails to notify Seller of Purchaser's election, Purchaser
          will be deemed to have elected to proceed with the purchase of all of
          the Property. In the event that Purchaser purchases all of the
          Property, Seller shall have no obligation to repair any such damage or
          destruction, nor shall the Purchase Price be adjusted except as
          provided in 8.1(b) below. "Materially Damaged or Destroyed" shall mean
          damage or destruction the repair or replacement of which, as
          determined by a licensed general contractor reasonably approved by
          Purchaser and Seller, would exceed $750,000 as to any casualty of a
          type against which insurance is maintained (a "Major Insured
          Casualty") or would exceed $100,000 as to any casualty against which
          insurance is not maintained (a "Major Uninsured Casualty"). If,
          between the Effective Date and the Closing Date, the Property sustains
          nonmaterial damage, the parties shall proceed to closing. If between
          the Effective Date and the Closing Date, the Property is Materially
          Damaged or Destroyed due to a Major Uninsured Casualty, Seller may
          elect in writing, within five (5) days after the Casualty Notice Date,
          to terminate this Agreement. If Seller fails to notify Purchaser of
          Seller's election, Seller will be deemed to


                                      -31-
<PAGE>

          have elected to proceed with the sale of all of the Property.

     (b)  If Purchaser elects or is required to purchase the Property despite
          such damage or destruction, Seller shall assign its rights to and
          Purchaser shall be entitled to receive any insurance proceeds (with
          any accrued interest thereon) at or after Closing (as the same are
          available) and Purchaser shall receive a credit toward the Purchase
          Price (i) for the insurance deductible relative to Seller's insurance
          on the Property with respect to an insured casualty, including a Major
          Insured Casualty, or (ii) for the cost of repair not covered by
          insurance with respect to an uninsured casualty, including a Major
          Uninsured Casualty. Seller shall reasonably cooperate with Purchaser
          to allow Purchaser to collect any available insurance proceeds. Seller
          agrees to maintain until the Closing the level of insurance coverage
          in effect on the Property as of the Effective Date.

     8.2  Condemnation.

     If prior to Closing all or a Material Part of the Property is subject to a
proposed taking by any public authority, Seller shall promptly notify Purchaser
in writing of such proposed taking and Purchaser may terminate this Agreement by
notice to Seller within five (5) days after written notice thereof. If Purchaser
so elects, this Agreement shall terminate. If Purchaser does not so elect to
terminate this Agreement, or if the taking is as to a non-Material Part of the
Property, Purchaser shall accept the Property subject to the taking without a
reduction in the Purchase Price and shall receive at closing an assignment of
all of Seller's rights to any condemnation award to the extent that such amount
does not exceed the Purchase Price plus any legal fees and expenses actually
expended in obtaining such award. Seller shall reasonably cooperate with
Purchaser to allow Purchaser to collect any such award. A "Material Part" of the
Property shall mean a taking which would exceed $750,000 as determined by a
licensed appraiser reasonably approved by Seller and Purchaser.

9. COMMISSIONS AND EXPENSES

     9.1 Payment of the Sale Commission.

estate broker or agent has been authorized to act on either parties' behalf
except Trenton Bonner/Business Real Estate Brokerage Company, Inc. ("Seller's
Agent") under a commission agreement between Seller and Seller's Agent, which
commission ("TB Commission") under said commission agreement Seller will pay to
Seller's Agent at Closing. Purchaser hereby indemnifies Seller and holds Seller
harmless from any and all demands or claims which now or hereafter may be
asserted against Seller for any brokerage fees, commissions or similar types of
compensation which may be claimed by any broker which was engaged or which
claims to have been engaged by Purchaser and all expenses and costs in handling

maintain the Property in its existing condition and repair, reasonable wear and
tear excepted, shall perform all work required to be performed by the landlord
under the terms of any Lease, except Seller shall not be required to perform any
repairs set forth in the PCM Proposal. In the event of the Closing, Purchaser
will not retain any existing employees and management agents of Seller for the
Property, and, accordingly, on the Closing, Seller shall (i) cause all
employment and management agreements respecting the Property to be terminated,
and deliver evidence of such termination to Purchaser, and (ii) remove all
employees and management personnel from the Property.

     Seller shall not, after the date of this Agreement, enter into any lease or
contract affecting the Property or any amendment thereof, which shall be an
obligation of Purchaser after Closing, or waive, compromise or settle any rights
of Seller under any contract or Lease which shall be assumed by Purchaser upon
Closing, or agree to return any security deposit, or modify, amend, or terminate
any contract which shall be assumed by Purchaser upon Closing, without in each
case obtaining Purchaser's prior written consent thereto. Seller shall terminate
prior to the Closing, at no cost or expense to Purchaser, any and all service or
management contracts related to the Property to which Seller is a party.

of the parties hereto and to their respective legal representatives, successors
and permitted assigns.

     11.7  Assignment.

     Seller's written consent shall be required for any assignment of
Purchaser's rights to a nominee under this Agreement. Any attempted unpermitted
assignment, except with Seller's prior written consent, shall be ineffective and
shall constitute a default under this Agreement. Notwithstanding any assignment
hereunder, Purchaser shall remain liable for the obligations of Purchaser under
this Agreement. Purchaser represents, warrants and certifies to Seller that
Purchaser has not assigned, transferred or encumbered or agreed to assign,
transfer or encumber, directly or indirectly, all or any portion of its rights
or obligations under this Agreement. Purchaser shall give written notice of any
proposed assignment at least five (5) business days prior to Closing. If Seller
approves such assignment, Seller shall have no obligation to reissue any
estoppels, surveys, or title commitments previously delivered to Purchaser, nor
shall Seller be responsible for any costs or expenses of any nature associated

          limited partners and/or shareholders of Seller and Purchaser, and
          employees, prospective lenders of Purchaser, attorneys, accountants,
          agents and affiliates of the parties who are involved in the ordinary

<PAGE>

          instructed to comply with the confidentiality provisions hereof; (ii)
          as required by law or in response to lawful process or subpoena or
          other valid or enforceable order of a court of competent jurisdiction;
          or (iii) in compliance with any filings required by the Securities and
          Exchange Commission ("SEC") or other federal or state agency.

     (b)  Notwithstanding anything to the contrary contained elsewhere herein,
          Purchaser hereby acknowledges that all information furnished by Seller
          to Purchaser or obtained by Purchaser in the course of Purchaser's
          investigation of the Property, or in any way arising from or relating
          to any and all studies or entries upon the Property by Purchaser, its
          agents or representatives, shall be treated as confidential
          information and further, that if any such confidential information is
          disclosed to third parties prior to the Closing, Seller may suffer
          damages and irreparable harm. In connection therewith, Purchaser
          hereby expressly understands, acknowledges and agrees (i) that
          Purchaser will not disclose any of the contents or information
          contained in or obtained as a result of any reports or studies made in
          connection with Purchaser's investigation of the Property, in any form
          whatsoever (including, but not limited to, any oral information
          received by Purchaser during the course of Purchaser's inspection of
          the Property), to any party prior to the Closing other than (a) the
          Seller, Seller's employees, agents or representatives, or Purchaser's
          agents, employees, representatives, attorneys, consultants or
          potential institutional lenders, without the prior express written
          consent of Seller (which consent shall not be unreasonably withheld),
          (b) as required by law or in response to lawful process or subpoena or
          other valid and enforceable order of a court of competent
          jurisdiction, and (c) as required by the SEC or other federal or state
          agency; (ii) that in making any disclosure of such information as
          permitted hereunder, Purchaser will advise said parties of the
          confidentiality of such information and the potential of damage to

                                      -38-
<PAGE>

          Seller as a result of any disclosure of such information by said third
          party, and (iii) that Seller is relying on Purchaser's covenant not to
          disclose any of the contents or information contained in any such
          reports or investigations to third parties (all of which is deemed to
          be confidential information by the provisions of this Section). In the
          event this Agreement is terminated, Purchaser agrees to return to
          Seller all information, studies, or reports Purchaser or Purchaser's
          agents have obtained from Seller or Seller's agents, contractors or
          representatives with respect to the Property or the condition of the
          Property. In the event either Purchaser or Purchaser's agents,
          employees, representatives, attorneys, consultants or potential
          institutional lenders cause a breach of Purchaser's duty of
          confidentiality hereunder, Purchaser shall be liable to Seller for
          damages and Seller may pursue all of its remedies afforded it under
          this Agreement. This provision shall survive (i) any termination of
          this Agreement and (ii) the Closing and not be merged therein.

     11.13  Termination.

     Upon termination of this Agreement for any reason by either party,
Purchaser shall have the obligation to return to Seller all Due Diligence
Documents and copies thereof (including the Survey) and any other information or
documentation received by Purchaser from Seller or Seller's agents with respect
to the Property and shall not disclose to any third party the contents thereof.
Seller shall not have any obligation to return or permit the return of any sums
due Purchaser upon any termination of this Agreement by Purchaser until the Due
Diligence Documents and copies thereof (including the Survey) and such other
information or documents provided to Purchaser by Seller or Seller's agents have
been returned to Seller.

will be deemed an original, and the counterparts taken together shall constitute
a single agreement.

     11.16 Limitation on Liability. Purchaser expressly agrees that the
obligations and liabilities of Seller under this Agreement and any document
referenced herein shall not constitute personal obligations of the officers,
directors, employees, agents, affiliates, members, representatives, partners,

subsection are solely for the convenience of the Purchaser and Seller and are
not a part of this Agreement and shall have no effect upon the construction or
interpretation of any part hereof. Whenever required by the context of this
Agreement, the singular shall include the plural and the masculine shall include
the feminine, and vice versa. This Agreement shall not be construed as if it had

AGREEMENT, SELLER SHALL BE ENTITLED TO TERMINATE THIS AGREEMENT AND RETAIN THE
AMOUNT OF THE DEPOSIT DESCRIBED IN SECTION 2.1 PLUS ANY ACCRUED INTEREST THEREON
(THE "SPECIFIED SUM") AS LIQUIDATED DAMAGES. SELLER AND PURCHASER ACKNOWLEDGE
THAT SELLER'S DAMAGES WOULD BE DIFFICULT TO DETERMINE, AND THAT THE SPECIFIED
SUM IS A REASONABLE ESTIMATE OF SELLER'S DAMAGES. SELLER AND PURCHASER
SPECIFICALLY FURTHER AGREE AFTER NEGOTIATION THAT THIS SECTION 12 IS INTENDED TO
AND DOES LIQUIDATE THE AMOUNT OF DAMAGES DUE SELLER, AND SHALL BE SELLER'S
EXCLUSIVE REMEDY AGAINST PURCHASER, BOTH AT LAW AND IN EQUITY ARISING FROM OR
RELATED TO A BREACH BY PURCHASER OF ITS OBLIGATION TO CONSUMMATE THE
TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. PROVISIONS OF THIS SECTION 12 SHALL
NOT BE CONSTRUED AS A LIMITATION ON THE OBLIGATIONS OF PURCHASER UNDER SECTIONS

EACH OF THE PARTIES TO ENTER INTO THIS TRANSACTION.

13. NO RECORDING

     The provisions hereof shall not constitute a lien on the Property and this
Agreement shall not be placed or suffered to be placed by Purchaser for
recording with the office of the recorder (clerk) for the county in which the
Property is located. Purchaser hereby appoints Seller as Purchaser's true and
lawful attorney-in-fact, coupled with an interest, for the purposes of the
execution of such documents and doing such acts as shall be necessary to effect
the discharge of the recording of this Agreement if such recording shall have
been accomplished in violation of the Section.

14. EFFECTIVENESS

     This Agreement shall only be effective if a counterpart is signed by both
Seller and Purchaser.

15. TAX-DEFERRED EXCHANGE

     At the option of Seller, this transaction may be part of a tax-deferred
exchange pursuant to United States Internal Revenue Code Section 1031 and
related regulations. If requested by Seller, Purchaser shall cooperate with
Seller to effect such assignments and other documents as Seller may require in
connection with the same; provided, however, that Purchaser shall not take title
to any property other than the Property or incur any additional liability on
account of such exchange and provided, further, that Seller shall reimburse
Purchaser for all costs and expenses, including attorneys' fees and costs,
incurred by Purchaser in connection with such exchange without prior consent.

16. RIGHT OF FIRST OFFER

     The parties hereto acknowledge that Seller's right to sell the Property is
subject to a certain right of first offer held by the James River Paper Company,
Inc. pursuant to its lease with Seller relative to the Property. In this regard,
Seller has, prior to the date hereof, advised the James River Paper Company,
Inc. of its intention to sell the Property, and has requested that the James
River Paper Company, Inc. confirm its decision to either exercise or waive its
right of first offer. Seller has been advised preliminarily of the James River
Paper Company, Inc.'s intention not to


                                      -42-
<PAGE>

exercise its right of first offer in connection with Seller's sale of the
Property, and Seller is awaiting written confirmation thereof. In the event,
however, that, prior to the Closing, the James River Paper Company, Inc. shall
elect to exercise such right of first offer and proceeds in accordance therewith
to close on its acquisition of the Property, Purchaser acknowledges and agrees
that Seller shall be unable to consummate the transaction contemplated herein,
and, in such event, Seller shall have the right to terminate this Agreement
prior to the Closing, in which event all documents and funds deposited by
Purchaser shall be immediately returned to Purchaser, all documents deposited by
Seller shall be immediately returned to Seller and neither party shall have any
further rights or obligations hereunder (except as set forth in Sections 3.6(b),
9.1, 11.2 and 11.12).

17. REIT

     Purchaser hereby advises Seller that Purchaser is qualified as a real
estate investment trust under the provisions of the Internal Revenue Code, and
that, by reason thereof, the maintaining of such status and the avoiding of any
activity which might cause a penalty tax to be applied is of material concern to
Purchaser. Accordingly, Seller agrees to make any modifications or amendments to
this Agreement reasonably requested by Purchaser prior to the expiration of the
Inspection Period that may be necessary for Purchaser to maintain its status as
a real estate investment trust or in order for it to avoid a penalty tax;
provided, however, that Seller shall have no obligation to enter into any such
modification or amendment that would materially alter or affect, in Seller's
sole judgment, Seller's rights, duties, or obligations under this Agreement.

     Property, as defined below, which arise or accrue on or after the Closing.



                                      C-1
<PAGE>


     2. Assignment. Assignor hereby conveys and assigns to Assignee all of its
right, title and interest in, to and under the following (collectively, the
"Assigned Property"):

          A. those certain tenant space leases set forth on Schedule B attached

     Delinquent Rents (as defined in the Purchase Agreement) and other
     additional rent and reimbursements payable under such tenant space leases
     and accruing prior to the Closing) after Closing and any and all security
     deposits in connection therewith;

     5. Claims. As a condition to the liability of the other party hereunder,
the claiming parting ("Claiming Party") shall notify the other party ("Other
Party"), in writing, of any claim ("Claim") covered by this Assignment within a
reasonable time after the assertion thereof by a third party against Other
Party. In the event of such a notice of a Claim by Claiming Party to Other
Party, Other Party shall have ten (10) days after receipt thereof in which to
undertake the defense of the Claim on behalf of itself and Claiming Party. If
Other Party so undertakes to defend said Claim on behalf of itself and Claiming
Party, it shall retain and pay counsel to conduct such defense. Such counsel
shall be subject to the approval of the Claiming Party which approval shall not
be unreasonably withheld or delayed. Claiming Party may employ its own
counsel to work with Other Party as counsel in connection with the defense of
said Claim, but Claiming Party shall pay all fees and disbursements of said
counsel. Other Party may settle the Claim, without the consent of Claiming
Party, to the extent the settlement does not bind Claiming Party or impose any
obligation on Claiming Party. If Claiming Party would have any liability for the
payment and/or performance of any settlement, Claiming Party's written consent
thereto must be obtained by Other Party in order for said settlement to be
binding upon Claiming Party.

     If Other Party refuses or fails to so undertake to defend the Claim,
Claiming Party may defend the same on its own behalf, may retain and pay counsel
to conduct such defense and may settle the Claim, without the consent of Other
Party. Other Party shall then reimburse Claiming Party (a) for all reasonable
costs, including court costs and reasonable attorneys' fees, incurred by
Claiming Party in connection with said defense and/or any such settlement, (b)
for all sums paid pursuant to any judgment interest against Claiming Party in
connection therewith.

               ("Title Company") covering the Real Property and Improvements and

               the  Property  and  showing  all  liens,  claims,   encumbrances,
               easements,    rights-of-way,     encroachments,     reservations,
               restrictions  and any  other  matters  of  record  affecting  the

          (c)  A copy of the survey of the Real  Property  and  Improvements  in

     3.2 Review of Title.

     Buyer shall have until  February  15, 1997 to review the Title  Commitment,
Title  Documents  and  Survey  (collectively  "Title  Evidence")  and render any
objections  as to matters of title in  writing  to Seller.  Any such  matters of
title  not  timely  objected  to by  Buyer  shall be  deemed  waived  and  shall
constitute additional permitted exceptions  ("Additional  Permitted Exceptions")
hereunder.  Seller shall have thirty (30) days from the date of such  objections
to have such objections removed or satisfied.  If Seller shall fail to have such
objections  removed or satisfied within such time or during such time delivers a
written notice to Buyer that notwithstanding  Seller's reasonable efforts,  such
objections may not be cured,  then Buyer may, at its sole  election,  within ten
(10) days of the first to occur of the expiration of said thirty (30) day period

either (a) terminate this  Agreement  without any liability on its part in which
case the Deposit  together with interest  thereon shall be refunded to Buyer and
neither party shall have further rights or obligations  hereunder (except as set
forth in Section 5.3(b) hereof) or (b) proceed to Closing and take title subject
to such  objections,  in which  case  such  non-cured  objections  shall  become
Additional  Permitted  Exceptions  hereunder.  Seller  agrees to use  reasonable
efforts to satisfy

<PAGE>


promptly any such title objections;  provided, however, that Seller shall not be
obligated to expend more than $10,000 in the aggregate in connection with curing
any such objections. Notwithstanding anything in this Agreement to the contrary,
Buyer  shall not object to, and agrees to acquire the  Property  subject to, the
initial  permitted  exceptions  described on Exhibit H attached hereto ("Initial
Permitted Exceptions",  with the Initial Permitted Exceptions and the Additional
Permitted  Exceptions  sometimes  hereinafter  collectively  referred  to as the
"Permitted Exceptions").

     3.3 Vesting of Title.

     At Closing,  Seller shall convey fee simple title to the Real  Property and
Improvements to Buyer by special warranty deed (as further  described in Section
4.2(a)(i) below), subject to the Permitted Exceptions, and shall convey Seller's
interest in the Personal Property to Buyer by bill of sale (as further described
in Section 4.2(a) (ii) below).

     3.4 Title Insurance.

     At Closing, the Title Company shall issue to Buyer a 1992 ALTA owner's form
of title insurance policy,  in the form that is customarily  issued in the State
of Texas or if an ALTA owner's form of policy is not available, then in the form
that is customarily issued in Texas,  together with any endorsements  reasonably
required  by Buyer  (but only to the  extent  available  in Texas)  and with the
survey  exception  amended to read "shortages in area only" in the amount of the
Purchase  Price  insuring  that  fee  simple  title  to the  Real  Property  and
Improvements is vested in Buyer subject to the Permitted  Exceptions (the "Title
Policy).

     3.5 Inspection Period.

     Buyer  shall have until  February  15,  1997 (the  "Inspection  Period") to
inspect the Property,  the Due Diligence  Documents (as  hereinafter  defined in
Section  5.3(b)),  and  perform  such other due  diligence  with  respect to the
Property as Buyer reasonably deems necessary.  Buyer may, upon written notice to
Seller,  received by Seller no later than 5:00 p.m. Central Time on the last day
of the  Inspection  Period,  elect to terminate  this  Agreement.  Upon any such
termination,  the Deposit  together with  interest  thereon shall be refunded to
Buyer and,  subject to Section 5.3(b)  hereof,  neither party shall have further
rights or  obligations  hereunder.  In the event no  notice  of  termination  is
received by Seller on or before such time,  then the Deposit,  together with all
accrued  interest  thereon,  shall become  non-refundable  (subject to the other
terms and  conditions of this  Agreement)  and Seller and Buyer shall proceed to
Closing in accordance  with the terms and  conditions  hereof and the Inspection
Period  termination  rights  shall be deemed  waived by Buyer.  Buyer  shall not
undertake   any  soil   borings,   ground  water  testing  or  other  "Phase  2"
investigative procedures without first having obtained the prior written consent
of Seller. In connection with Buyer's  inspection of the Property,  Buyer agrees
that:

          (a)  All inspection fees,  engineering  fees, or other expenses of any
               kind incurred by Buyer relating to the inspection of the Property
               will be at Buyer's sole cost and expense;


                                       4
<PAGE>


          (b)  Buyer  will  advise  Seller  at least  two (2)  business  days in
               advance of the dates of all  inspections  and will  schedule  all
               tests and  inspections  during  normal  business  hours  whenever
               feasible unless otherwise requested by Seller;

          (c)  Seller will have the right to have one or more representatives of
               Seller  accompany  Buyer and Buyer's  representatives,  agents or
               designees while they are on the Property;

          (d)  Any entry by Buyer, its representatives, agents or designees will
               not  unreasonably  interfere with Seller's use of the Property or
               with the operations of any tenant;

          (e)  Buyer will  restore any damage  caused to the Property by Buyer's
               entry on the  Property  for  inspection  purposes at Buyer's sole
               cost and expenses if this transaction does not close; and

          (f)  In making  any  inspection  hereunder,  Buyer will treat and will
               cause  any  representative  of  Buyer to  treat  all  information
               obtained  by Buyer  pursuant  to the terms of this  Agreement  as
               strictly confidential in accordance with Section 11.12 below.

Purchaser  shall have the right to further  inspect the Property  within the two
(2)  business  day period  immediately  preceding  the  Closing  (during  normal
business hours and upon notice to Seller) for the purpose of confirming that the
Property is in the same  condition  at Closing as existing at end of  Inspection
Period, reasonable wear and tear excepted; provided, however, that such right of
pre-closing  inspection  shall in no way be deemed to  extend or  resurrect  the
Inspection Period or constitute a condition to Closing; subject, however, to the
other terms and conditions of this  Agreement.  For purposes of this  Agreement,
the term "business day" shall mean a day other than any Saturday, Sunday, or day
upon which  national  banks in the City of San  Antonio,  Texas are not open for
general banking business.

     The  Covenants  of Buyer  contained  in this  Section  3.5(a) and (e) shall
survive Closing Date or any earlier termination of this Agreement.

     Seller  agrees to use  reasonable  efforts  to  operate  and  maintain  the
Property in a manner  generally  consistent  with the manner in which Seller has
operated and maintained the Property prior to the effective date  (including any
scheduled renovations to the Improvements).

                          5. PRORATIONS; CLOSING ITEMS

     5.1 Prorations; Closing Costs.

     (a)  The amount due on any gas,  electric,  water,  sewer, or other utility
          bill, or service  contract  relating to the Property shall be prorated
          between  Seller and Buyer as of the Closing  Date,  to the extent such
          utilities or service  contracts  are the  obligation of the Seller and
          not a direct  or  indirect  obligation  of the  tenants.  Any  utility
          deposits made by Seller shall be and remain the property of Seller.

     (b)  All  collected  rents and other  payments  from each tenant  under the
          Leases,  including,  but not limited to, base rent,  additional  rent,
          percentage  rent  (if  any),  and  expense  reimbursements,  shall  be
          prorated  between Seller and Buyer as of the Closing Date. The balance
          remaining  from any  security  deposits or prepaid rent held by Seller
          shall be credited to Buyer  (including  the balance of estimated  tax,
          insurance  and  common  area  maintenance  payments  made to Seller by
          tenants under the Leases net of any payments by Seller thereon). Buyer
          agrees to  indemnify  and hold  harmless  Seller  from and against any
          loss, cost or expense (including, but not limited to, attorneys' fees)
          resulting  from any claim for such  deposits or prepaid  rent.  If any
          rent or other payments under the Leases are, in




                                       8
<PAGE>




          arrears as of the Closing Date ("Delinquent Rents"), the amount of any
          such  Delinquent  Rents which are collected by Buyer shall be promptly
          paid by Buyer to Seller  after  Closing.  Buyer  shall be  entitled to
          deduct  from  any  such  payment  (i)  Buyer's   reasonable  costs  of
          collection incurred with respect to such tenant (including  attorneys'
          fees),  (ii) rents due for the month in which such payment is received
          by Buyer, and (iii) rents from such tenant  attributable to any period
          after  the  Closing  that are past due on the date of  receipt.  Buyer
          agrees to use commercially  reasonable  efforts to collect  Delinquent
          Rents after the Closing  provided Buyer shall not be required to bring
          any action or  proceeding  against any Tenant on account of Delinquent
          Rents.  Seller may make reasonable efforts to collect Delinquent Rents
          from and after the Closing Date; provided,  however, that Seller shall
          not be entitled  to pursue any action for  eviction of any tenant from
          the Property.

     (c)  All real estate taxes  attributable to the Property due and payable in
          the calendar year in which the Closing occurs (i.e.,  1997 real estate
          taxes due  October 1, 1997 and  delinquent  February 1, 1998) shall be
          prorated  as of the  Closing  provided  Seller  shall be  entitled  to
          recover any  reimbursements  from Tenants on account of such taxes for
          the period  prior to  Closing,  and Buyer shall  immediately  remit to
          Seller any such reimbursements received by Buyer upon receipt thereof.
          Any real estate taxes  (exclusive of tenant  payment  thereof) due and
          payable in any calendar  year which is (i) prior to the calendar  year
          in which Closing occurs  (including 1996 real estate taxes due October
          1, 1996 and  delinquent  February 1, 1997) shall be the  obligation of
          Seller and Seller shall pay all such taxes,  including any interest or
          penalty thereon, prior to Closing, and (ii) subsequent to the calendar
          year in which the Date of Closing  occurs shall be the  obligation  of
          Buyer.  If Closing shall occur before the actual real estate taxes for
          the year of Closing (i.e., 1997 taxes) are known, the apportionment of
          real estate taxes shall be upon the basis of the real estate taxes for
          the Property for the immediately  preceding year, provided that if the
          taxes for the current  year are  thereafter  determined  to be more or
          less than the real  estate  taxes for the  preceding  year  (after any
          appeal in assessed  valuation thereof is concluded),  Seller and Buyer
          promptly  shall  adjust the  proration  of such real estate  taxes and
          Seller or Buyer, as the case may be, shall pay to the other any amount
          required  as a result of such  adjustment.  Seller and Buyer  agree to
          mutually  cooperate  with each other in  connection  with  ongoing tax
          reduction  proceedings  relating to prior tax years,  if any,  and any
          ongoing or future  proceedings  relating  to the tax year in which the
          Closing  occurs,  if any, and any refund  resulting  therefrom (to the
          extent  not  refundable  to the  tenants  under the  Leases)  shall be
          prorated  between  Seller and Buyer based on the Closing  Date,  after
          deducting therefrom the reasonable  out-of-pocket expenses incurred by
          the parties. The provisions of the immediately preceding two sentences
          shall survive Closing and shall not be merged therein.

     (d)  Buyer shall pay for the cost of recording  the Deeds,  the cost of any
          endorsements or special coverages of any nature in connection with the
          Title Policy (including



                                       9
<PAGE>



     without  limitation any amendment of the survey  exception to "shortages in
     area  only"),  one-half  (l/2) of any escrow fees and  closing  fees to the
     Title Company,  any surveys  prepared by or at the direction of Buyer,  any
     lender's title insurance coverage,  and any mortgage taxes or other similar
     taxes,  fees or  assessments,  and pay any sales tax in connection with the
     transfer of the Personal  Property.  Buyer shall pay for all costs relating
     to any financing  obtained by Buyer in connection  with its purchase of the
     Property and all costs  incurred by Buyer in  performing  any related tests
     and investigations.  Seller shall pay the base premium for the Title Policy
     (without the cost of any endorsements or special coverages)  one-half (1/2)
     of all escrow fees and closing fees charged by the Title  Company,  and the
     recording  fees with respect to documents  which Seller  elects to place of
     record in order to cure  title  objections  raised  by Buyer to the  extent
     Seller  elects to cure the same,  as fully  described  in said Section 3.3.
     Each party shall pay its own attorney's fees.

     5.2 Calculation of Prorations.

     For  purposes of  calculating  prorations,  Seller shall be deemed to be in
title to the  Property,  and  therefore  entitled  to the income  therefrom  and
responsible for the expenses thereof,  through the day prior to the Closing Date
and Buyer shall be deemed to be in title to the Property, and therefore entitled
to the income therefrom and responsible for the expenses thereof, from and after
12:01 a.m. on the Closing Date. All prorations shall be made on the basis of the
actual number of days of the year and month which have elapsed as of the Closing
Date.  Except as otherwise stated above, if necessary,  the amount of prorations
shall be adjusted  in cash after  Closing,  as and when  complete  and  accurate
information  becomes available but in any event no later than one hundred twenty
(120) days after the Closing Date;  provided,  however,  the one hundred  twenty
(120) day period shall be extended for a reasonable  time for any real  property
tax reduction or abatement  proceeds which are to be prorated  between Buyer and
Seller  pursuant to the last  sentence  of Section  5.1(c) and for any period of
time which may be required for reconciliation of tax, insurance, and common area
maintenance  expenses  for the  calendar  year in which the Closing Date occurs.
Buyer and Seller each agree to reasonably  cooperate with the other with respect
to such final  proration.  This provision shall survive Closing and shall not be
merged therein.

          office of the Property  Manager or otherwise.  Seller shall reasonably
          cooperate  with Buyer to obtain any  consents  required in  connection
          with an assignment of any of the Due Diligence  Documents.  All of the
          Due Diligence  Documents are confidential and shall not be distributed

          OF ANY MATERIALS,  DOCUMENTS,  REPORTS, OR AGREEMENTS  DESCRIBED ABOVE
          SHALL NOT BE INTERPRETED IN ANY MANNER AS A REPRESENTATION OR WARRANTY
          OF ANY TYPE OR KIND BY SELLER, PROPERTY MANAGER, ANY PARTNER OF SELLER
          OR AGENT OF SELLER, OR ANY OFFICER,  DIRECTOR,  OR EMPLOYEE OF SELLER,
          OR PROPERTY  MANAGER,  OR ANY OTHER PARTY RELATED IN ANY WAY TO ANY OF
          THE FOREGOING.

                        6. REPRESENTATIONS AND WARRANTIES

     6.1 Seller's Representations and Warranties.

     Seller hereby represents and warrants to Buyer as follows:

     (a)  Seller's  Entity.  Seller is a Delaware  corporation  duly  organized,
          validly  existing and in good standing  under the laws of the State of
          Delaware.

     (b)  Seller  Authority.  Seller has full power and  authority to enter into
          this Agreement and to perform all its obligations  hereunder,  and has
          taken all  action  required  by law,  its  governing  instruments,  or
          otherwise to authorize the  execution,  delivery,  and  performance of
          this Agreement and all the deeds, agreements,  certificates, and other
          documents  contemplated  herein. This Agreement has been duly executed
          by and is a valid and  binding  agreement  of Seller,  enforceable  in
          accordance with its terms,  except as enforceability may be limited by
          equitable  principles  or by the laws of  bankruptcy,  insolvency,  or
          other laws affecting creditors' rights generally.

     (c)  No  Conflict  or Lien.  Neither  the  execution  or  delivery  of this
          Agreement nor the consummation of the transactions contemplated herein
          will conflict with or result in a breach of any contract,  license, or
          undertaking to which Seller is a party or by


                                       12
<PAGE>





          which any of its property is bound, or constitute a default thereunder
          or, except as contemplated herein,  result in the creation of any lien
          or encumbrance upon the Premises.

     (d)  No Proceedings. No legal or administrative proceeding is threatened or
          pending  against  Seller  which  would  adversely  affect its right to
          convey the Premises to Buyer as contemplated in this Agreement.

     (e)  Leases.  Seller has  delivered to Buyer a correct and complete copy of
          each Lease and all amendments thereto.  The information  regarding the
          Leases  contained  on the Rent  Roll  attached  here as  Exhibit  K is
          correct  and  complete  as of  the  date  of  this  Agreement.  To the
          knowledge  of  Seller,  the  Leases  are in full  force and effect and
          neither Seller, nor any tenant, is in default under the Leases.  There
          are no other  leases or  possessory  rights of  others  regarding  the
          Property except as described in Exhibit K.

     (f)  Seller  has no  knowledge  of  and  has  not  received  notice  of any
          litigation  which has been filed against Seller that arises out of the
          ownership of the Property and would materially  affect the Property or
          use thereof, or Seller's ability to perform hereunder.

     (g)  Seller has no knowledge of and has not  received  written  notice from

          Agreement or to purchase all of the  Property  without  regard to such
          damage or  destruction.  If Buyer  fails to notify  Seller of  Buyer's
          election,  Buyer will be deemed to have  elected  to proceed  with the
          purchase of all



                                       18
<PAGE>


          of  the  Property.  In  the  event  that  Buyer  purchases  all of the
          Property, Seller shall have no obligation to repair any such damage or
          destruction,  nor shall the Purchase Price be adjusted except that the

          Buyer and Seller. If, between the Effective Date and the Closing Date,
          the  Property  sustains  nonmaterial  damage,  Seller shall assign its
          rights to  insurance  proceeds,  if any,  as  provided  for in Section
          8.1(b) below. Seller agrees to maintain until the Closing the level of
          insurance coverage in effect on the Property as of the Effective Date,
          which insurance coverage is maintained at a replacement cost level.

     (b)  If Buyer elects or is required to purchase  the Property  despite such
          damage or  destruction,  Seller  shall  assign its rights to and Buyer

          interest  thereon) at or after  Closing  (as the same are  available).

          any available insurance proceeds.

proposed taking by any public  authority,  Seller shall promptly notify Buyer in
writing of such proposed taking and Buyer may terminate this Agreement by notice
to Seller within  fifteen (15) days after written  notice  thereof.  If Buyer so
elects,  this Agreement  shall be of no further force and effect.  If Buyer does
not so terminate this Agreement,  or if the taking is as to a non-Material  Part
of the Property, Buyer shall accept the Property subject to the taking without a
reduction in the Purchase  Price and shall  receive at closing an  assignment of
all of  Seller's  rights to any  condemnation  award.  Seller  shall  reasonably
cooperate with Buyer to allow Buyer to collect any such award. A "Material Part"
of the Property  shall mean a taking which would exceed twenty  percent (20%) or
more of the Purchase Price the Property,  as determined by a licensed  appraiser

          public disclosure concerning this transaction shall be made, and each
          party agrees to use best efforts to prevent disclosure of this
          transaction, other than (i) to directors and officers of the parties,
          limited partners of Buyer, and employees, prospective mortgage

          by the Securities and Exchange Commission ("SEC") or other federal or
          state agency.

     (b)  Notwithstanding anything to the contrary contained elsewhere herein,
          Buyer hereby acknowledges that all information furnished by Seller to
          Buyer or obtained by Buyer in the course of Buyer's investigation of
          the Property, or in any way arising from or relating to any and all
          studies or entries upon the Property by Buyer, its agents or
          representatives, shall be treated as confidential information and
          further, that if any such confidential information is disclosed to

          not limited to, any oral information received by Buyer during the
          course of Buyer's inspection of the Property), to any party prior to
          the Closing other than (a) the Seller, Seller's employees, agents or
          representatives, or Buyer's agents, employees, representatives,
          attorneys, consultants or potential institutional lenders, without the
          prior express written consent of Seller (which consent shall not be
          unreasonably withheld), (b) in response to lawful process or subpoena
          or other valid and or enforceable order of a court of competent
          jurisdiction, and (c) as required by the SEC or other federal or state
          agency; (ii) that in making any disclosure of such information as
          permitted hereunder, Buyer will advise said parties of the
          confidentiality of such information and the potential of damage to
          Seller as a result of any disclosure of such information by said third
          party, and (iii) that Seller is relying on Buyer's covenant not to
          disclose any of the contents or information contained in any such
          reports or investigations to third parties (all of which is deemed to
          be confidential information by the provisions of this Section). In the
          event this Agreement is terminated, Buyer agrees to return to Seller
          all information, studies, or reports Buyer or Buyer's agents have
          obtained from Seller or Seller's agents, contractors or
          representatives with respect to the Property or the condition of the
          Property. In the event either Buyer or Buyer's agents, employees,
          representatives, attorneys, consultants or potential institutional

and shall not disclose to any third party the contents thereof. Seller shall not
have any obligation to return any sums due Buyer, upon any termination of this
Agreement by Buyer, until the Due Diligence Documents and copies thereof
(including the Surveys) and such other information or documents provided to
Buyer by Seller or Seller's agents have been returned to Seller.

        2.  Assignment.  Assignor  hereby conveys and assigns to Assignee all of
its right title and interest in, to and under the following  (collectively,  the
"Assigned Property"):

                                       C-1


<PAGE>



        A. those  certain  tenant  space  leases set forth on Exhibit B attached
hereto;

        B.  those  certain  equipment  leases  set forth on  Exhibit C  attached
hereto, to the extent assignable;

        C. those certain  commission  agreements set forth on Exhibit D attached

        F.  all  unexpired  warranties,   permits,  approvals,  licenses,  legal
certificates,  and  authorizations  pertaining  to the  Property,  to the extent
assignable;

        G. the trade name "Alamo  Towers",  except that this  assignment is made
without  warranty of title to such name or of Assignee's  right to the exclusive
use of such name, and Assignee hereby  acknowledges that Assignor may never have
used or registered such trade name; and

        H. all other  intangibles  pertaining  to the  Property,  to the  extent
assignable.

        3. Assumption.  Assignee hereby assumes and agrees timely to perform the
Assumed Obligations.

        4. Indemnity.  Assignee hereby indemnifies and agrees to defend and hold
harmless  Assignor from any loss, cost,  claim,  liability  expense or demand of
whatever  nature  arising  from any breach or failure of  Assignee to observe or
perform any of the Assumed  Obligations.  Assignor hereby indemnifies and agrees
to defend and hold harmless  Assignee  from any loss,  cost,  claim,  liability,
expense  or demand of  whatever  nature  arising  from any  breach or failure of
Assignor to observe or perform any of the Accrued Obligations.

        5. Claims.  As a condition to  liability of Other Party  hereunder,  the
claiming party ("Claiming  Party") shall notify the other party ("Other Party"),
in  writing,  of any  claim  ("Claim")  covered  by  this  Assignment  within  a
reasonable  time after the  assertion  thereof by a third  party  against  Other
Party.  In the  event of such a notice  of a Claim  by  Claiming  Party to Other
Party,  Other Party shall have ten (10) days after  receipt  thereof in which to
undertake  the defense of the Claim on behalf of itself and Claiming  Party.  If
Other Party so  undertakes to defend said Claim on behalf of itself and Claiming
Party,  it shall  retain and pay counsel to conduct such  defense.  Such counsel
shall be subject to the approval of the Claiming  Party which approval shall not
be unreasonably  withheld or delayed.  Claiming Party may employ its own counsel
to work with  Other  Party as  counsel in  connection  with the  defense of said
Claim, but Claiming Party shall pay all fees and  disbursements of said counsel.
Other Party may settle the Claim, without the

                                       C-2


<PAGE>



consent of Claiming  Party,  to the extent the settlement does not bind Claiming
Party or impose any obligation on Claiming  Party.  If Claiming Party would have
any liability for the payment  and/or  performance of any  settlement,  Claiming
Party's  written  consent  thereto  must be obtained by Other Party in order for
said settlement to be binding upon Claiming Party.

        If Other  Party  refuses or fails to so  undertake  to defend the Claim,
Claiming Party may defend the same on its own behalf, may retain and pay counsel
to conduct such  defense and may settle the Claim,  without the consent of Other
Party.  Other Party shall then  reimburse  Claiming Party (a) for all reasonable
costs,  including  court  costs and  reasonable  attorneys'  fees,  incurred  by
Claiming Party in connection with said defense and/or any such  settlement,  (b)
for all sums paid by Claiming Party in accordance with any such settlement,  and
(c) for all sums paid pursuant to any judgment entered against Claiming Party in
connection therewith.

        IN WITNESS WHEREOF,  Assignor and Assignee have executed this Assignment
as of the date first set forth above.
