ITEM 1.  BUSINESS

Formation Transactions

     Prentiss Properties Trust (the "Company") was formed under the laws of the
state of Maryland on July 12, 1996, to be a self-administered and self-managed
real estate investment trust ("REIT").  The Company acquired a sole general
partnership interest in Prentiss Properties Acquisition Partners, L.P. (the
"Operating Partnership") through the Company's wholly-owned subsidiary Prentiss
Properties I, Inc., a Delaware corporation and owns an approximate 86.0% limited
partnership interest in the Operating Partnership.

     The Company has been formed to succeed to substantially all of the
interests of Prentiss Properties Limited, Inc. ("PPL") and its affiliates in (i)
a portfolio of office and industrial properties and (ii) the national
acquisition, property management, leasing, development and construction
businesses of PPL and its affiliates (the "Prentiss Group").  The acquisition,
property management, leasing, development and construction businesses will be
carried out by the Operating Partnership and the Company's majority-owned
affiliates, Prentiss Properties Limited, Inc. and Prentiss Properties Limited
II, Inc. (collectively, the "Manager").

     On October 22, 1996, the Company commenced operations after completing an
initial public offering of 16,000,000 common shares of beneficial interest,
$0.01 par value per share("Common Shares").  The Company issued an additional
2,400,000 Common Shares on November 1, 1996, pursuant to the exercise of the
underwriters' over-allotment option.  The combined 18,400,000 Common Shares were
issued at a price per share of $20.00 (the "Offering").  The Company used
approximately $87.4 million of the net proceeds of the Offering and issued
1,879,897 Common Shares of the Company for a total consideration of
approximately $125.0 million to purchase certain limited partners' interests in
the Operating Partnership.  The Company contributed the remaining net proceeds
of the Offering to the Operating Partnership.  Subsequent to these transactions,
the Company held an approximate 86.0% interest in the Operating Partnership.

     The Prentiss Group members, who, prior to the Offering, collectively served
as the general partner of the Operating Partnership, contributed to the
Operating Partnership all of their interests in the Operating Partnership, the
Initial Properties (as defined below) that were not owned by the Operating
Partnership, and certain management contracts of PPL (the "Contracts") in
exchange for 3,295,995 limited partnership units in the Operating Partnership
("Units").

     Upon completion of the Offering and certain related transactions
(collectively, the "Formation Transactions"), the Company owned 87 properties
(the "Initial Properties"), which consisted of 28 office (the "Initial Office
Properties") and 59 industrial (the "Initial Industrial Properties") containing
an aggregate of 8.9 million net rentable square feet.  Between the closing of
the Offering and December 31, 1996, the Company acquired eight additional
properties, (the "1996 Acquired Properties").  As of December 31, 1996, the
Company owned 95 properties, 33 office and 62 industrial (the "Properties")
containing 9.9 million square feet and located in 12 major markets throughout
the U.S.

     The 1996 Acquired Properties consist of five Class "A" suburban office
properties (the "1996 Acquired Office Properties") totaling approximately
850,000 square feet and three suburban industrial properties (the "1996 Acquired
Industrial Properties") totaling approximately 226,000 square feet.  The 1996
Acquired Office Properties are located in the Chicago, Illinois; Denver,
Colorado; and Northern Virginia markets.  The 1996 Acquired Industrial
Properties are located in the Chicago, Illinois market.  The purchase price of
the 1996 Acquired Properties totaled approximately $116.6 million (excluding
closing costs), which was funded principally with borrowings under the Line of
Credit totaling $72.8 million, other indebtedness incurred or assumed directly
by the Company totaling $35.0 million and approximately $8.8 million of cash
reserves.

     The location, acquisition date, number of buildings, net rentable square
feet and contract purchase price of the 1996 Acquired Properties is set forth in
the following table.  See "Item 2. Properties" for additional information
relating to the Company's Properties.

     Upon the closing of the Offering, the Operating Partnership closed a three-
year revolving credit facility (the "Line of Credit") with Bank One, Texas, N.A.
and NationsBank of Texas, N.A., initially in the amount of $100 million, which
was subsequently increased to $150 million on January 24, 1997.  The Operating
Partnership may borrow under the Line of Credit to finance the acquisition of
additional properties and for other corporate purposes, including to obtain
additional working capital.  Borrowings under the Line of Credit will bear
interest at the 30-day, 60-day or 90-day London Interbank Offered Rate ("LIBOR")
at the option of the Company, plus 2.00% initially per annum (which was reduced
to 1.75% on January 24, 1997), and is collaterialized by first mortgage liens on
certain of the Initial Properties (and may be collaterialized by other
properties acquired by the Company) and will be guaranteed by the Company.  At
December 31, 1996, the Company had aggregate borrowings from sources other than
its Line of Credit of $56.0 million and $72.8 million of borrowings under its
Line of Credit.  Reference is made to "Item 7. Management's Discussion and
Analysis of Financial Condition and Results of Operations - Liquidity and
Capital Resources" for additional information regarding the Company's Line of
Credit and other outstanding indebtedness.


ITEM 2.  PROPERTIES

     The Properties consist of the 33 office properties (the "Office
Properties") comprising approximately 4.7 million net rentable square feet and
the 62 industrial properties (the "Industrial Properties") comprising
approximately 5.3 million net rentable square feet. All of the Properties are
wholly owned by the Company (through its subsidiaries), except the Broadmoor
Austin Properties, which are owned by a joint venture in which the Company owns
a 49.9% managing general partnership interest, and One Northwestern Plaza, in
which the Company owns a 100% leasehold interest.

expected to have a material adverse effect on the business or financial
condition of the Company.


ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

     No matter was submitted to a vote of security holders of the Company during
the fourth quarter of 1996, through the solicitation of proxies or otherwise.

October 17, 1996 through December 31, 1996 .........   25-1/8  20-1/2

  Shareholder Information

     At March 14, 1997, the Company had approximately 81 holders of record and
approximately

1,800 beneficial owners, of its Common Shares.  In addition, the Units of
limited partner interest in the Operating Partnership (which are redeemable for
Common Shares subject to certain limitations) were held by 9 entities and
or persons.

  Distribution Information

     The Company has adopted a policy of paying regular quarterly distributions
on its Common Shares and cash distributions have been paid on the Company's
Common Shares with respect to the period since its inception.  The following
table sets forth information regarding the declaration and payment of
distributions by the Company since its commencement of operations on October 22,
1996.

October 22, 1996 - December 31, 1996..    12/31/96       1/17/97         $0.31(1)
</TABLE>

    (1) Represents the pro rata portion (for the period from October 22, 1996
        (inception of operations) through December 31, 1996) of a quarterly
        distribution of $0.40 per share.

     The foregoing distribution represents an approximate 57% return of capital
in 1996.  In order to maintain its qualification as a REIT, the Company must
make annual distributions to its shareholders of at least 95% of its taxable
income (which does not include net capital gains).  During the period from
October 22, 1996 to December 31, 1996 the Company declared distributions
totaling $0.31 per share, of which approximately $0.13 per share was required to
satisfy the 95% distribution test for maintaining its qualification as a REIT.
Under certain circumstances the Company may be required to make distributions in
excess of cash available for distribution in 

                                       6
<PAGE>
 
order to meet such REIT distribution requirements. In such event, the Company
presently would expect to borrow funds, or to sell assets for cash, to the
extent necessary to obtain cash sufficient to make the distributions required to
retain its qualification as a REIT for federal income tax purposes.

     The Company has declared a cash distribution for the first quarter of 1997
in the amount of $.40 per share, payable on April 17, 1997 to holders of record
on March 31, 1997.  The Company currently anticipates that it will maintain at
least the current distribution rate for the immediate future, unless actual
results of operations, economic conditions or other factors differ from its
current expectations.  Future distributions, if any, paid by the Company will be
at the discretion of the Board of Trustees of the Company and will depend on the
actual cash flow of the Company, its financial condition, capital requirements,
the annual distribution requirements under the REIT provisions of the internal
revenue code and such other factors as the Board of Trustees of the Company deem
relevant.

  Recent Sales of Unregistered Securities

     On July 24, 1996, the Company was capitalized with the issuance to Michael
V. Prentiss of 50 Common Shares at $20 per share for an aggregate purchase price
of $1,000.  The Common Shares were purchased as an investment and for the
purpose of organizing the Company.  The Company issued these Common Shares in
reliance on an exemption from registration under Section 4(2) of the Securities
Act.

     On October 22, 1996, the Company privately placed an aggregate of 1,879,897
Common Shares with three institutional investors, in exchange for a portion of
such investors' interests in the Operating Partnership.  The Common Shares were
acquired for investment and the transaction occurred in connection with the
Offering and related Formation Transactions.  The Company issued these Common
Shares in reliance upon an exemption from registration under Section 4(2) of the
Securities Act.

     Effective January 1, 1997, the Company issued an aggregate of 500 Common
Shares of the Company to the Independent Trustees (defined in Item 10. "Trustees
and Executive Officers of the Company") in accordance with the Trustees Plan as
described in "Item 11. Executive Compensation--Trustees Plan."


ITEM 6.  SELECTED FINANCIAL AND OPERATING DATA

     The following sets forth selected financial and operating data for the
Company on a pro forma and historical consolidated basis and the Predecessor
Company (as defined in Item 7. "Management's Discussion and Analysis of
Financial Condition and Results of Operations") on a historical combined basis.
The following data should be read in conjunction with the financial statements
and notes thereto and Management's Discussion and Analysis of Financial
Condition and Results of Operations included elsewhere in this Form 10-K.  The
pro forma statement of operations and other data for the year ended December 31,
1996 include the historical results of the Company's operations from its
commencement of operations on October 22, 1996 to December 31, 1996, and the
historical results of the Predecessor Company's operations for the period of
January 1, 1996 to October 21, 1996, adjusted to assume that the Offering and
related Formation Transactions and the application of the net proceeds therefrom
and the acquisition of properties had occurred at the beginning of the pro forma
period presented.   The pro forma financial information is not necessarily
indicative of what the financial position and result of operations of the
Company would have been as of the dates and for the periods indicated, nor does
it purport to represent or project the financial position and results of
operations for future periods.

     Historical operating results of the Company and Predecessor Company,
including net income, may not be comparable to future operating results. In
addition, the Company believes that the book value of the Properties, which
reflects historical costs of such real estate assets less accumulated
depreciation, is not indicative of the fair value of the Properties.

 (4) EBITDA means operating income before mortgage and other interest, income
     taxes, depreciation and amortization. The Company believes EBITDA is useful
     to investors as an indicator of the Company's ability to service debt and
     pay cash distributions. EBITDA, as calculated by the Company, is not
     comparable to EBITDA reported by other REITs that do not define EBITDA
     exactly as the Company defines that term. EBITDA does not represent cash
     generated from operating activities in accordance with GAAP, and should not
     be considered as an alternative to operating income or net income as an
     indicator of performance or as an alternative to cash flows from operating
     activities as an indicator of liquidity. The Company's EBITDA for the
     respective periods is calculated as follows:

(5)  The Company generally considers funds from operations an appropriate
     measure of liquidity of an equity REIT because industry analysts have
     accepted it as a performance measure of equity REITs. "Funds from
     Operations," as defined by the National Association of Real Estate
     Investment Trusts ("NAREIT"), means net income (computed in accordance
     with GAAP) excluding gains (or losses) from debt restructuring and sales of
     property, plus depreciation and amortization on real estate assets, and
     after adjustments for unconsolidated partnerships and joint ventures. The
     Company's Funds from Operations are not comparable to Funds from Operations
     reported by other REITs that do not define that term using the current
     NAREIT definition. The Company believes that in order to facilitate a clear
     understanding of the combined historical operating results of the Prentiss
     Group and the Company, Funds from Operations should be examined in
     conjunction with net income (loss) as presented in the audited consolidated
     and combined financial statements and notes thereto of the Company and
     Predecessor Company included elsewhere in this Form 10-K. Funds from
     Operations does not represent cash generated from operating activities in
     accordance with GAAP and should not be considered as an alternative to net
     income as an indication of the Company's performance or to cash flows as a
     measure of liquidity or ability to make distributions. The Company's and
     Predecessor Company's Funds from Operations for the respective periods is
     calculated as follows:

financial statements and related notes thereto for the Company and the
Predecessor Company, respectively, appearing elsewhere in this Form 10-K. The
following discussion is based primarily on the consolidated financial statements
of the Company for the period subsequent to the Offering and on the combined
financial statements of the Predecessor Company for the periods prior to the
Offering.  The combined financial statements of the Predecessor Company include
(i) the results of operations from 47 properties for the periods presented, (ii)
the results of operations of the 3141 Fairview Park Drive property for the
portion of the periods after a Prentiss Group member acquired the property,
(iii) the results of operations of the Plaza on Bachman Creek for the portion of
the periods after a Prentiss Group member acquired the property, (iv) a 25%
equity interest in the Broadmoor Austin properties, (v) a 15% equity interest in
the Park West C2 property for the portion of the periods in which the Prentiss
Group owned a non-controlling interest, and (vi) results of operations of the
Prentiss Properties Service Business conducted primarily by Prentiss Properties
Limited, Inc. ("PPL") in the periods presented. The properties owned by the
Operating Partnership, prior to the Formation Transactions, consist of
Cumberland Office Park, 5307 East Mockingbird, Walnut Glen Tower, 8521 Leesburg
Pike, all of the industrial properties in Baltimore, Maryland, except 9050
Junction Drive, and all of the industrial properties in Kansas City, Missouri;
Dallas, Texas; and Milwaukee, Wisconsin.

     Historical results set forth in the "Selected Financial and Operating
Data," the combined financial statements of the Predecessor Company, and the
consolidated financial statements of the Company should not be taken as an
indication of future operations of the Company.

OVERVIEW

     The Company was formed under the laws of the state of Maryland on July 12,
1996, to be a self-administered and self-managed real estate investment trust
("REIT").  The Company acquired a sole general partnership interest in Prentiss
Properties Acquisition Partners, L.P. (the "Operating Partnership") through the
Company's wholly-owned subsidiary Prentiss Properties I, Inc., a Delaware
corporation and owns an approximate 86.0% limited partnership interest in the
Operating Partnership.

     The Company has been formed to succeed to substantially all of the
interests of PPL and its affiliates in (i) a portfolio of office and industrial
properties and (ii) the national acquisition, property management, leasing,
development and construction businesses of PPL and its affiliates (the "Prentiss
Group").  The acquisition, property management, leasing, development and
construction businesses will be carried out by the Operating Partnership and the
Company's majority-owned affiliates, Prentiss Properties Limited, Inc. and
Prentiss Properties Limited II, Inc. (collectively, the "Manager").

     On October 22, 1996, the Company commenced operations after completing an
initial public offering of 16,000,000 Common Shares.  The Company issued an
additional 2,400,000 Common Shares on November 1, 1996 pursuant to the exercise
of the underwriters' over-allotment option.  The combined 18,400,000 Common
Shares were issued at a price per share of $20.00 (the "Offering").  The Company
used approximately $87.4 million of the net proceeds of the Offering and issued
1,879,897 Common Shares of the Company for a total consideration of
approximately $125.0 million to purchase certain limited partners' interests in
the Operating Partnership.  The Company contributed the remaining net proceeds
of the Offering to the Operating Partnership.  Subsequent to these transactions,
the Company held an approximate 86.0% interest in the Operating Partnership.

                                       10
<PAGE>
 
     The Prentiss Group members, who, prior to the Offering, collectively served
as the general partner of the Operating Partnership, contributed to the
Operating Partnership all of their interests in the properties and certain
management contracts of PPL (the "Contracts") in exchange for 3,295,995 limited
partnership units in the Operating Partnership ("Units").

     At December 31, 1996, the Company owned 95 properties containing
approximately 9.9 million square feet, compared to the 55 properties containing
approximately 6.3 million square feet owned by the Predecessor Company at
December 31, 1995. The property acquisitions containing approximately 300,000
square feet were made by the Predecessor Company between December 31, 1995 and
October 21, 1996. Concurrent with the Offering, the Company acquired 30
properties with approximately 2.2 million square feet and an additional 25%
interest in a joint venture owning seven properties in which the Predecessor
Company had an existing 25% ownership interest. Subsequent to the Offering,
through December 31, 1996, the Company acquired eight properties containing
approximately 1.1 million square feet.

RESULTS OF OPERATIONS

     The results of operations for the years ended December 31, 1995 and 1994
includes the operations of the Predecessor Company.  The results of operations
for the year ended December 31, 1996 includes the operations of the Predecessor
Company for the period January 1, 1996 through October 21, 1996 and the
operations of the Company from October 22, 1996 through December 31, 1996.


Comparison of Year Ended December 31, 1996 to Year Ended December 31, 1995

     Rental revenues increased by $11.1 million, or 37.9%, due primarily to the
Properties acquired after December 31, 1995.  Revenues for the Properties
acquired prior to December 31, 1995 increased by $0.6 million, or 2%, due
primarily to increases in rental income at the Cumberland Office Park of $0.4
million, 5307 E. Mockingbird of $0.3 million, Walnut Glen of $0.2 million and
8521 Leesburg Pike of $0.5 million, offset by decreases of $0.4 million, $0.3
million and $0.1 million at the Kansas City and Milwaukee Industrial Properties
and other Properties, respectively.  The decreases at the Kansas City Industrial
Properties resulted primarily from the expiration of a 200,000 square foot lease
during the first half of 1996.  In February 1997, 100% of this Property was
leased and the recognition of rental income commenced.  The decrease in the
Milwaukee Industrial Properties resulted primarily from the March 1996
bankruptcy of a tenant previously occupying approximately 70,000 square feet.
The Company is currently marketing the space for lease.

     With respect to Properties acquired prior to December 31, 1995, property
operating and maintenance expenses increased by $0.6 million for the year ended
December 31, 1996 from the year ended December 31, 1995, $0.3 million of which
relates to bad debt expense recognized on the above-mentioned bankrupt tenant.
The additional costs relates primarily to the Properties with increased rental
income during 1996.

     Real estate taxes, on these Properties, increased by $0.3 million,
resulting primarily from increased property tax appraisals received on the
Cumberland Office Park and Walnut Glen Properties. The Company continues to
contest these increases.

Comparison of Year Ended December 31, 1995 to Year Ended December 31, 1994

     Total Revenues increased by $3.2 million, or 6.2%, to $55.2 million for the
year ended December 31, 1995 from $52.0 million for the same period in 1994.
Rental revenues increased $4.2 million, or 16.5%, to $29.4 million from $25.3
million, primarily as a result of the Company's acquisition of certain
Industrial Properties in Baltimore, Maryland, and 8521 Leesburg Pike in late
1994 and two additional Industrial Properties in Kansas City, Missouri, in May
1994.  These Property additions accounted for approximately $2.9 million of the
increase in rental income; the remaining increase in rental income of
approximately $1.2 million was the result of increased rental rates and
occupancy rates in the existing portfolio which are estimated at $0.9 million
and $0.3 million, respectively.  Fee and other income decreased $1.0 million, or
3.6%, to $25.7 million from $26.7 million, primarily due to a decrease in
development fees of $5.1 million and a decrease in leasing and tenant services
fees of $1.9 million, offset by an increase in sale fees, other fees and other
income of $6.1 million. The decrease in development fees was primarily due to
the recognition of a significant fee in 1994 coupled with low development

                                       11
<PAGE>
 
activity during 1995. The leasing and tenant services fee decreases were due to
higher space rollover and leasing activity in 1994. Sale fees and other fees
increased due to property sales and fees received as a result of contract
termination payments.

     Total Expenses increased by $0.6 million, or 1.3%, to $45.2 million for the
year ended December 31, 1995, from $44.6 million for the same period in 1994.
Operating expenses decreased by $.1 million, or 0.2%, to $41.3 million from
$41.4 million. Operating expenses includes a decrease of $1.1 million in
compensation of the Manager's shareholders. Shareholder compensation was based
on earnings of the Manager and was a means of distributing those earnings to the
shareholders. The Manager had other decreases in operating expenses of $1.8
million which primarily was related to personnel cost reductions. Operating
expenses of the properties increased by $2.8 million. This increase was
comprised of an increase in property operating and maintenance expenses of $0.9
million, an increase of $0.3 million in real estate taxes and an increase of
$1.6 million in depreciation and amortization. Approximately $2.0 of the
increase in property operating expense was attributable to the property
additions discussed previously and the remainder of the increase, $0.9 million
was attributable to increased occupancy and an increase in amortization expense.
Mortgage interest expense increased $0.7 million, or 21.7%, to $3.9 million for
the year ended December 31, 1995 from $3.2 million for 1994. This increase was
primarily the result of new financing related to acquisitions during the period
along with additional financing obtained on the Dallas industrial properties.

     Gains on sale of property for the year ended December 31, 1994, was $1.7
million.  This gain was the result of the sale of an industrial building in
Ontario, California. The property was purchased in 1993.

     Net income for the year ended December 31, 1995 increased by $0.9 million,
or 9.9%, to $10.0 million from $9.1 million for 1994. As discussed above, the
increase in net income was the result of an increase in total revenues of $3.2
million, offset by an increase in total expenses of $0.6 million, and a decrease
in gains on sale of property of $1.7 million.


LIQUIDITY AND CAPITAL RESOURCES

     Cash and cash equivalents were $7.2 million and $1.0 million at December
31, 1996 and December 31, 1995, respectively. The increase in cash and cash
equivalents is primarily a result of cash flows provided by operating and
financing activities exceeding cash flow used in investing activities. Net cash
provided by operating activities was $22.5 million for the year ended December
31, 1996 compared to the $16.2 million for the year ended December 31, 1995. The
increase is due primarily to the transactions related to the property
acquisitions and the operations of the Company subsequent to the Offering.

     Net cash used in investing activities increased from $4.3 million for the
year ended December 31, 1995 to $386.8 million for the year ended December 31,
1996.  This increase is due primarily to the transactions related to the
Offering and acquisition of real estate assets subsequent to the Offering.

     Net cash provided by financing activities of $372.0 million for the year
ended December 31, 1996 increased from a cash use of $20.0 million for the year
ended December 31, 1995.  This increase is primarily attributable to
transactions related to the Offering and mortgage loans and other indebtedness
incurred in the acquisition of real estate assets acquired subsequent to the
Offering.

     Cash and cash equivalents were $1.0 million and $9.1 million at December
31, 1995 and 1994, respectively. The decrease in cash and cash equivalents is
primarily a result of cash flows used by investing activities exceeding those
provided by operating and financing activities. Net cash provided by operating
activities in 1995 increased by $3.2 million compared to 1994. The increase was
primarily attributable to the incremental increase in cash flow from operations
provided by properties acquired in 1994 and an approximately $1.9 million
increase in earnings from the Manager. The increase in the Manager's earnings
was primarily due to reductions in operating expenses. Net cash used by
investing activities in 1995 decreased by $36.6 million compared to 1994. The
decrease was primarily a result of the acquisition of properties in 1994. These
acquisitions were funded primarily through capital contributions and the
addition of new real estate loans. Net cash provided by (used in) financing
activities in 1995 decreased by $55.4 million compared to 1994. The decrease was
primarily attributable 

                                       12
<PAGE>
 
to partner distributions of $15.3 million in 1995, compared to partner
contributions, and new real estate loans of $12.1 million and $27.1 million,
respectively, in 1994.

     At December 31, 1996, the Company had total outstanding indebtedness of
approximately $198.7 million (the ''Mortgage Debt''), including the Company's
pro rata share of the Broadmoor Austin Properties debt (Joint Venture Debt).
The Mortgage debt was collateralized by 66 of the Properties. The Mortgage Debt
represents approximately 25.2% of the Company's approximate $788 million Total
Market Capitalization (based on the $25 closing price of individual shares at
December 31, 1996). Approximately $40.0 million of the Mortgage Debt consists of
a mortgage loan that the Company obtained from an affiliate of Lehman Brothers
Inc. and approximately $72.8 million represents borrowings the Company has made
under the Line of Credit.  The following table sets forth certain information
regarding the Mortgage Debt at December 31, 1996:

(1) The Line of Credit is collateralized by 33 Properties, including 16 Office
    Properties.  The 30-day LIBOR of 5.50% as of December 31, 1996, was used for
    the calculation of the weighted average rate in the table above.

(2) The Other Mortgage Debt is collateralized by 24 Industrial Properties.  The
    30-day LIBOR of 5.50% as of December 31, 1996 was used for the calculation
    of the weighted average rate in the table above.

     On January 24, 1997, the Company increased the amount available under the
Line of Credit from $100 million to $150 million and reduced the interest rate
on borrowings under the Line of Credit from LIBOR plus 200 basis points to LIBOR
plus 175 basis points.  The Company currently has no amounts outstanding under
the Line of Credit.

     On February 27, 1997, the Company closed on a ten-year fixed rate mortgage
loan with an initial total available balance of $180.1 million, and $96.1
million outstanding (the "Mortgage Loan").  The Mortgage Loan is secured by
liens on 54 Properties.  The Mortgage Loan was obtained from an affiliate of
Lehman Brothers Inc. ("Lehman"), the Managing Underwriter of the IPO.  The
Mortgage Loan bears interest at a rate of approximately 7.57% and matures on
February 27, 2007.  A portion of the proceeds of the Mortgage Loan were used to
repay approximately $88.2 million of outstanding indebtedness under the Line of
Credit.  The balance of the proceeds from the Mortgage Loan will be used to fund
a portion of the purchase prices of future acquisitions.  Lehman has advised the
Company that it intends to place the Mortgage Loan with investors sometime in
the future.

     Pursuant to the Debt Limitation, the Company's combined indebtedness plus
its pro rata share of Joint Venture Debt is limited so that, at the time such
debt is incurred, it does not exceed 50% of the Company's Total Market
Capitalization. The Predecessor Company had total outstanding indebtedness of
30.9% and 29.3% as of December 31, 1995 and December 31, 1994, respectively.  As
of December 31, 1996, the Company had the approximate capacity to borrow up to
an additional $390.6 million under the Debt Limitation. The amount of
indebtedness that the Company may incur, and the policies with respect thereto,
are not limited by the Company's Declaration of Trust and Bylaws and are solely
within the discretion of the Company's Board of Trustees.

     The Company has considered its short-term liquidity needs and the adequacy
of adjusted estimated cash flows and other expected liquidity sources to meet
these needs. The Company believes that its principal short-term liquidity needs
are to fund normal recurring expenses, debt service requirements and the minimum
distribution required to maintain the Company's REIT qualification under the
Code. The Company anticipates that these needs will be fully funded from the
Company's initial working capital and the cash flows provided by operating
activities and, when necessary to fund shortfalls resulting from the timing of
collections of accounts receivable in the ordinary course of business, from the
Line of Credit.

                                       13
<PAGE>
 
     The Company expects to meet its long-term liquidity requirements for the
funding of activities such as development, property acquisitions, scheduled debt
maturities, major renovations, expansions and other non-recurring capital
improvements through long-term secured and unsecured indebtedness and the
issuance of additional equity securities from the Company and the Operating
Partnership. The Company also intends to use proceeds from the Line of Credit to
fund property acquisitions, development, redevelopment, expansions and capital
improvements on an interim basis.

     The Company expects to make distributions to its shareholders primarily
based on its distributions from the Operating Partnership. The Operating
Partnership's income will be derived primarily from lease revenues from the
Properties and operations of the Manager.  The Manager's sole source of income
is fees generated by its office and industrial real estate management, leasing,
development and construction businesses.


FUNDS FROM OPERATIONS

     The Company generally considers Funds from Operations an appropriate
measure of liquidity of an equity REIT because industry analysts have accepted
it as a performance measure of equity REITs.  "Funds from Operations", as
defined by the NAREIT, means net income (computed in accordance with GAAP),
excluding gains (or losses) from debt restructuring and sales of property, plus
depreciation and amortization on real estate assets, and after adjustments for
unconsolidated partnerships and joint ventures.  The Company believes that in
order to facilitate a clear understanding of its operating results, Funds from
Operations should be examined in conjunction with net income (loss) as presented
in the audited consolidated and combined financial statements of the Company and
Predecessor Company, respectively.  Funds from Operations does not represent
cash generated from operating activities in accordance with GAAP and should not
be considered as an alternative to net income as an indication of the Company's
performance or to cash flows as a measure of liquidity or ability to make
distributions.

INFLATION

     Most of the leases on the Properties require tenants to pay increases in
operating expenses, including common area charges and real estate taxes, thereby
reducing the impact on the Company of the adverse effects of inflation. Leases
also vary in terms from one month to 15 years, further reducing the impact on
the Company of the adverse effects of inflation.

TERMS OF OFFICE; RELATIONSHIPS

     The officers of the Company are elected annually by the Board of Trustees
at a meeting held preceding each annual meeting of shareholders, or as soon
thereafter as necessary and convenient in order to fill vacancies or newly
created offices.  Each officer holds office until his successor is duly elected
and qualified or until death, resignation or removal, if earlier.  Any officer
or agent elected or appointed by the Board of Trustees may be removed by the
Board of Trustees whenever in its judgment the best interests of the Company
will be served thereby, but such removal shall be without prejudice to the
contractual rights, if any, of the person so removed.

     There are no family relationships among any of the Trustees or executive
officers of the Company.  Except as described above, none of the Company's
Trustees hold trusteeships in any company with a class of securities registered
pursuant to Section 12 of the Securities Exchange Act of 1934 (the "Exchange
Act") or pursuant to Section 15(d) of the Exchange Act or any company registered
as an investment company under the Investment Company Act of 1940.  There are no
arrangements or understandings between any Trustee or officer and any other
person pursuant to which that Trustee was nominated or officer was selected.

COMPLIANCE WITH SECTION 16(a) OF THE SECURITIES EXCHANGE ACT OF 1934

     Section 16 (a) of the Exchange Act requires officers and Trustees, and
persons who beneficially own more than ten percent (10%) of the Company's
shares, to file initial reports of ownership and reports of changes in ownership
with the Securities and Exchange Commission ("SEC").  Officers, Trustees and
greater than ten percent (10%) beneficial owners are required by SEC regulations
to furnish the Company with copies of all Section 16(a) forms they file.

     Based solely on a review of the copies furnished to the Company and
representations from the officers and Trustees, the Company believes that all
Section 16(a) filing requirements for the year ended December 31, 1996
applicable to its officers, Trustees and greater than ten percent (10%)
beneficial owners were satisfied, with the exception of the following:

     On October 22, 1996, Mr. Mark R. Doran acquired beneficial ownership of 400
of the Company's Common Shares. Mr. Doran reported his acquisition of the 400
Common Shares of the Company on his Form 5 which was filed on February 3, 1997.

     Based on written representations from the officers and Trustees, the
Company believes that no other Forms 5 for Trustees, officers and greater than
ten percent (10%) beneficial owners were required to be filed with the SEC for
the period ended December 31, 1996.

EMPLOYMENT AGREEMENTS

  Messrs. Prentiss and August entered into employment agreements with the
Company on October 22, 1996. Each agreement is for an initial term of three
years, which will be automatically renewed for successive one-year periods
unless otherwise terminated. The agreements provide for base annual compensation
(as set forth in ''--Executive Compensation'' above) and incentive compensation
to be determined by the Compensation Committee (within the terms set forth in
''--Incentive Compensation" below). Each employment agreement provides that the
Compensation Committee may approve increases in the base salaries. Each of the
employment agreements provides for certain severance payments in the event of
disability or termination by the Company without cause or by the employee with
cause. No other employee of the Company is employed pursuant to an employment
agreement.

  The terms of Messrs. Prentiss' and August's employment agreements require that
Messrs. Prentiss and August devote substantially all of their business time to
the affairs of the Company. These agreements also, subject to certain
exceptions, prohibit them from engaging, directly or indirectly, during the term
of their employment or the Noncompetition Period (as defined below), in any
activity anywhere in the U.S. that competes with the Company (the "Competitive
Activities"). These provisions of each employment agreement survive the
termination of such agreement until the expiration of the Noncompetition Period.
The "Noncompetition Period" is the period beginning on the date of the
termination of employment with the Company and ending on the second anniversary
of such date.

  Mr. DuBois entered into a noncompetition agreement with the Company that,
subject to certain limited exceptions, prohibits him from engaging, directly or
indirectly, in Competitive Activities in the Southeastern U.S. and the
Southwestern U.S., respectively, during the Noncompetition Period. In the event
of an involuntary termination of Mr. DuBois' employment, the agreement does not
prohibit him from engaging in Competitive Activities, but, during the
Noncompetition Period, does prohibit him from (1) soliciting any employee of the
Company to leave his or her job and (ii) soliciting any client or identified
potential client of the Company during the Noncompetition Period.

1996 SHARE INCENTIVE PLAN

  Prior to the Offering, the Board of Trustees adopted, and the sole shareholder
of the Company approved, the 1996 Plan for the purpose of attracting and
retaining executive officers, Trustees and employees. The 1996 Plan is
administered by the Compensation Committee of the Board of Trustees, or its
delegate. The Compensation Committee may not delegate its authority with respect
to grants and awards to individuals subject to Section 16 of the Exchange Act.
As used in this summary, the term ''Administrator'' means the Compensation
Committee or its delegate, as appropriate.

  Officers and other employees of the Company, the Operating Partnership and
designated subsidiaries, including the Manager, generally will be eligible to
participate in the 1996 Plan. The Administrator selects the individuals who will
participate in the 1996 Plan (the ''Participants''). No Participant may be
granted, in any calendar year, options that cover more than 390,000 Common
Shares or SARs that cover more than 390,000 Common Shares.  Options granted with
tandem SARs shall be treated as a single award for purposes of applying the
limitation in the preceding sentence.  No Participant may be issued, in any
calendar year, more than 50,000 

                                       20
<PAGE>
 
Common Shares pursuant to an award of Restricted Shares (defined below) or
Performance Shares (defined below) for more than 50,000 Common Shares.

  The 1996 Plan authorizes the issuance of up to 2,030,000 Common Shares. The
Plan provides for the grant of (i) share options not intended to qualify as
incentive share options under Section 422 of the Code, (ii) Performance Shares,
(iii) SARs, issued alone or in tandem with options, (iv) Restricted Shares,
which are contingent upon the attainment of performance goals or subject to
vesting requirements or other restrictions and (v) incentive awards. The
Administrator shall prescribe the conditions which must occur for Restricted
Shares to vest or for Performance Shares to vest and incentive awards to be
earned.

  In connection with the grant of options under the 1996 Plan, the Administrator
will determine the option exercise period and any vesting requirements. The
initial options granted under the Plan will have 10-year terms and will become
exercisable for one-third of the covered shares (disregarding fractional shares,
if any) on the first and second anniversaries of the date of grant, and for the
balance of the shares on the third anniversary of the date of grant subject to
acceleration of vesting upon a change in control of the Company (as defined in
the 1996 Plan). An option may be exercised for any number of whole shares less
than the full number for which the option could be exercised. A Participant will
have no rights as a shareholder with respect to Common Shares subject to his or
her option until the option is exercised. To the extent an option has not become
exercisable at the time of a Participant's termination of employment, it will be
forfeited unless the Administrator exercises its discretion to accelerate
vesting for the Participant. If a Participant is terminated due to dishonesty or
similar reasons, all unexercised options, whether vested or unvested, will be
forfeited. Any Common Shares subject to options which are forfeited (or expire
without exercise) pursuant to the vesting requirement or other terms established
at the time of grant will again be available for grant under the 1996 Plan. The
exercise price of options granted under the 1996 Plan may not be less than the
fair market value of the Common Shares on the date of grant. Payment of the
exercise price of an option granted under the 1996 Plan may be made in cash,
cash equivalents acceptable to the Compensation Committee or, if permitted by
the option agreement, by exchanging Common Shares having a fair market value
equal to the option exercise price.

  On the effective date of the Offering, options for 1,219,438 Common Shares
were granted to employees and officers, including the officers named in
"Executive Compensation" above, at an exercise price equal to $20.00.  On
November 4, 1996, the Board of Trustees authorized the grant of 1,500 options to
employees with ten or more years of service with the Company.  Through December
31, 1996, 37,500 options were granted at an exercise price equal to $20.625 per
share.  On December 17, 1996, the Board of Trustees authorized the grant of
395,000 options in total to various officers and employees at an exercise price
equal to $23.375 per share.

  No option, SAR, Restricted Shares, incentive award or Performance Shares may
be granted under the 1996 Plan after December 31, 2006. The Board may amend or
terminate the 1996 Plan at any time, but an amendment will not become effective
without shareholder approval if the amendment materially (i) increases the
number of shares that may be issued under the 1996 Plan (other than an
adjustment or automatic increase described above); (ii) changes the eligibility
requirements; or (iii) increases the benefits that may be provided under the
1996 Plan. No amendment will affect a Participant's outstanding award without
the Participant's consent.

INCENTIVE COMPENSATION

  The Company may award incentive compensation to employees of the Company and
its subsidiaries, including incentive awards under the 1996 Plan that may be
earned on the attainment of performance objectives stated with respect to
criteria described above or other performance-related criteria. The Compensation
Committee may, in its discretion, approve bonuses to executive officers and
certain other officers and key employees if the Company achieves Company-wide,
regional and/or business unit performance objectives determined by it each year.
To the extent a bonus exceeds 100% of such an employee's base salary, the
Company may pay such excess in Restricted Shares.

THE TRUSTEES' PLAN

  Prior to the Offering, the Board of Trustees also adopted, and the Company's
sole shareholder approved, the Trustees' Plan to provide incentives to attract
and retain Independent Trustees.

                                       21
<PAGE>
 
  The Trustees' Plan provides for the grant of options and the award of Common
Shares to each eligible Trustee of the Company.  No Trustee who is an employee
of the Company, the Operating Partnership, or designated subsidiaries, including
the Manager, is eligible to participate in the Trustees' Plan.

  The Trustees' Plan provides that each Independent Trustee who is a member of
the Board of Trustees on the effective date of the Offering (a "Founding
Trustee") will be granted an option for 10,000 Common Shares at an exercise
price equal to the Offering Price. Each Independent Trustee who is not a
Founding Trustee will receive an option for 10,000 Common Shares on the date of
the first Board of Trustees meeting following the annual meeting of shareholders
at which the Independent Trustee is first elected to the Board of Trustees;
provided, however, that an Independent Trustee (other than a Founding Trustee)
who is first elected or appointed to the Board of Trustees other than at an
annual meeting of shareholders shall receive an option for 10,000 Common Shares
on the date of such election or appointment. The exercise price of options
granted in accordance with the preceding sentence shall be the fair market value
of a Common Share on the date of grant. The exercise price of options granted
under the Trustees' Plan may be paid in cash, acceptable cash equivalents,
Common Shares or a combination thereof. Options issued under the Trustees' Plan
are exercisable for ten years from the date of grant.

  An option granted under the Trustees' Plan shall become exercisable for 2,500
Common Shares on each of the first through fourth anniversaries of the date of
grant, provided that Trustee is a member of the Board of Trustees on such
anniversary date. To the extent an option has become exercisable under the
Trustees' Plan, it may be exercised whether or not the Trustee is a member of
the Board on the date or dates of exercise. An option may be exercised for any
number of whole shares less than the full number for which the option could be
exercised. A Trustee will have no rights as a shareholder with respect to Common
Shares subject to his or her option until the option is exercised.

  On the effective date of the Offering, options for 50,000 Common Shares were
granted to the Independent Trustees at an exercise price equal to $20.00 per
share.

  Each Independent Trustee will also receive quarterly an award of Common
Shares. Awards will be made on each March 1, June 1, September 1 and December 1
(each date, a "Quarterly Award Date") during the term of the Trustees' Plan.
Each Independent Trustee will receive, on each Quarterly Award Date on which he
or she is a member of the Board of Trustees, the number of Common Shares having
a fair market value on that date that as nearly as possible equals, but does not
exceed, $2,500. A Trustee will be immediately and fully vested in all such
Common Shares awarded to him or her under the Trustees' Plan.

  The terms of outstanding options, the number of Common Shares for which
options will thereafter be awarded, and the number of Common Shares to be
awarded on a Quarterly Award Date shall be subject to adjustment in the event of
a share dividend, share split, combination, reclassification, recapitalization
or other similar event.

  The Trustees' Plan provides that the Board of Trustees may amend or terminate
the Trustees' Plan, but the Trustees' Plan may not be amended more than once
every six months other than to comply with changes in the Internal Revenue Code,
the Employee Retirement Income Security Act of 1974, or the rules thereunder. An
amendment will not become effective without shareholder approval if the
amendment materially changes the eligibility requirements or increases the
benefits that may be provided under the Trustees' Plan. No options for Common
Shares may be granted and no Common Shares may be awarded under the Trustees'
Plan after December 31, 2002.

SAVINGS PLAN

  The Company intends to continue, and the Operating Partnership and designated
subsidiaries, including the Manager (each, a "Participating Employer"), have
adopted, the Employee Savings Plan & Trust (the "401(k) Plan") of PPL which
was originally adopted in 1987. Prior service with PPL will be credited in full
as service with the Company or a Participating Employer for all purposes under
the 401(k) Plan, including eligibility and vesting.
  Each employee of the Company and a Participating Employer may enroll in the
401(k) Plan on March 1, June 1, September 1, and December 1 after completing one
year and 1,000 hours of service and attaining age 21 (an enrolled employee is a
"Plan Participant"). Plan Participants are immediately vested in their pre-tax
and after-tax contributions, matching and discretionary Company contributions,
and earnings thereon.

                                       22
<PAGE>
 
  The 401(k) Plan permits each Plan Participant to elect to defer up to 15% of
base compensation, subject to the annual statutory limitation ($9,500 for 1996)
prescribed by Section 402(g) of the Code, on a pre-tax basis. Plan Participants
may also elect to make an after-tax contribution of up to 8% of their base
compensation. The Company and the Participating Employers will make matching
contributions equal to 25% of amounts deferred up to $500 in deferrals. The
Company and the Participating Employers may also make annual contributions if
the Company achieves certain performance objectives to be determined on an
annual basis by the Compensation Committee. Matching and discretionary
contributions will be made in cash or Common Shares.

SHARE PURCHASE PLAN

  The Company adopted a "Share Purchase Plan." Under the Share Purchase Plan,
employees of the Company, the Operating Partnership, and designated
subsidiaries, including the Manager, will be able to purchase Common Shares
directly from the Company at a 15% discount to the then-current market value at
the date of purchase. Purchases may be made by any employee with more than one
full year of continuous employment on the last business day each of June and
December. An employee's purchases, on an annual basis, under the Share Purchase
Plan will be limited to the lesser of 15% of the employee's base salary or
$25,000. The maximum number of Common Shares that may be purchased under the
Share Purchase Plan is 500,000. Employees who participate in the plan described
in the preceding sentence will recognize income, and the Company will be allowed
a business expense deduction, equal to the discount at the time of a purchase.

COMPENSATION OF TRUSTEES

  The Company intends to pay its Trustees who are not officers of the Company
fees for their services as Trustees. Each such Trustee will receive annual
compensation of $10,000 in Common Shares payable quarterly and a fee of $1,250
plus expenses for attendance in person at each meeting of the Board of Trustees,
$250 for each telephonic meeting of the Board of Trustees and $500 for each
committee meeting attended. In addition, each such Trustee will receive options
under the 1996 Trustees' Share Incentive Plan (the "Trustees' Plan") to
purchase 10,000 Common Shares at an exercise price equal to the Offering Price,
which options will vest in equal installments over a four-year period on the
anniversary of the date of grant. Officers of the Company who are Trustees will
not be paid any trustee fees.

        COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION ON
                            COMPENSATION DECISIONS

  During 1996, the Company's Compensation Committee of the Board of Trustees
consisted of Thomas J. Hynes, Jr., Leonard M. Riggs, Jr., and Lawrence A.
Wilson,  constituting all of the Independent Trustees, none of whom was, prior
to or during 1996, an officer or employee of the Company.  None of such persons
had any relationships requiring disclosure under applicable rules and
regulations.  The Company did not have a policy during 1996 prohibiting its
executive officers from participating in deliberation of the Board of Trustees
regarding executive compensation.  Consequently, Messrs. Prentiss and August,
who are also Trustees of the Company, were present during deliberations of the
Board of Trustees regarding executive compensation during 1996.  Messrs.
Prentiss and August, in their capacities as Trustees, participated in such
deliberations.


ITEM 12. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS

  The following table sets forth information, as of March 14, 1997, regarding
each person known to the Company to be the beneficial owner of more than five

SECURITY OWNERSHIP OF MANAGEMENT

  The following table sets forth the beneficial ownership of Common Shares of
(i) each person who is a shareholder of the Company owning more than 5% of the
beneficial interest in the Company, (ii) each person who is a Trustee, Trustee
nominee or executive officer of the Company and (iii) the Trustees and executive
officers of the Company as a group. Unless otherwise indicated in the footnotes,
all of such interests are owned directly, and the indicated person or entity has
sole voting and investment power. The number of shares represents the number of
Common Shares the person is expected to hold plus the number of shares for which
Units expected to be held by the person are redeemable (if the Company elects to
issue Common Shares rather than pay cash upon such redemption). The extent to
which the persons will hold Common Shares as opposed to Units is set forth in
the notes.

ITEM 13.   CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

BENEFITS TO RELATED PARTIES

  The Prentiss Group, including the Prentiss Principals, realized certain
benefits as a result of the Offering and the Formation Transactions, including
the following:

  Receipt of Units by the Prentiss Group.   Members of the Prentiss Group
received a total of 3,295,995 Units in consideration for their interests in the
Properties, the Development Parcels, the Options and the Prentiss Properties
Service Business in connection with the Formation Transactions. These Units
(representing approximately 14% of the equity interests in the Company on a
consolidated basis) have a total value of approximately $82.4 million based
on the $25.00 December 31, 1996 closing price per share, compared to a net
tangible book value of the assets contributed to the Operating Partnership by
the Prentiss Group of approximately $4.7 million. The Company believes that the
net tangible book value of the individual assets contributed to the Operating
Partnership by the Prentiss Group (which reflects the historical cost of such
assets less accumulated depreciation), is less than the aggregate current market
value of such assets. Any time after two years following the Closing Date, the
members of the Prentiss Group holding Units may, in accordance with the
Operating Partnership Agreement, exchange all or a portion of such Units for
cash or, at the election of the Company, Common Shares on a one-for-one basis.
The Company currently expects that it will not elect to pay cash for Units in
connection with any such exchange request, but instead will exchange Common
Shares for such Units. The Units may provide the members of the Prentiss Group
with increased liquidity and, until disposition of certain assets contributed to
the Company, with continued deferral of the taxable gain associated with those
assets.

  Increase in Prentiss Group's Net Tangible Investment.   Members of the
Prentiss Group realized an immediate increase of $45.7 million in the net
tangible book value of their original $4.7 million investment in the Company.
The immediate increase is derived from the difference between the net tangible
assets per share before and after the Formation Transactions multiplied by the
3,295,995 Units received as consideration.

  Messrs. Prentiss and August Employment Agreements.   Prior to the IPO, Messrs.
Prentiss and August entered into employment agreements with the Company.  Each
agreement is for an initial term of three years, which will be automatically
renewed for successive one-year periods unless otherwise terminated. The
agreements provide for base annual compensation (as set forth in "--Executive
Compensation" above) and incentive compensation to be determined by the
Compensation Committee (within the terms set forth in "--Incentive Compensation"
above). Each employment agreement provides that the Compensation Committee may
approve increases in the base salaries. Each of the employment agreements
provides for certain severance payments in the event of disability or
termination by the Company without cause or by the employee with cause. No other
employee of the Company is currently employed pursuant to an employment
agreement.

  The terms of Messrs. Prentiss' and August's employment agreements require that
Messrs. Prentiss and August devote substantially all of their business time to
the affairs of the Company. These agreements also, subject to 

                                       26
<PAGE>
 
certain exceptions, prohibit them from engaging, directly or indirectly, during
the term of their employment or the Noncompetition Period, in any activity
anywhere in the U.S. that competes with the Company. These provisions of each
employment agreement survive the termination of such agreement until the
expiration of the Noncompetition Period.

  Mr. DuBois entered into noncompetition agreements with the Company that,
subject to certain limited exceptions, prohibit them from engaging, directly or
indirectly, in Competitive Activities in the Southeastern U.S. and the
Southwestern U.S., during the Noncompetition Period. In the event of an
involuntary termination of Mr. DuBois' employment, the agreement does not
prohibit him from engaging in Competitive Activities, but, during the
Noncompetition Period, does prohibit him from (1) soliciting any employee of the
Company to leave his or her job and (ii) soliciting any client or identified
potential client of the Company during the Noncompetition Period.

  Options Granted.   The Company has granted to the Prentiss Principals, 70
employees of the Company and the Independent Trustees, options to purchase an
aggregate of 1,651,938 Common Shares under the Company's 1996 Share Incentive
Plan at the Offering Price, subject to certain vesting requirements.

  Maintenance of Debt for Benefit of Prentiss Principals. In connection with the
Formation Transactions, the Company agreed to maintain at least $1.3 million of
indebtedness secured by certain of the Properties outstanding for three years
and to permit certain Prentiss Group members to guaranty such debt through
December 31, 1998 in order to defer certain tax consequences associated with the
Formation Transactions.

  Restriction on Certain Transfers of The Plaza on Bachman Creek. The Company
agreed that it shall not dispose of The Plaza on Bachman Creek prior to
December 31, 1999, unless such disposition is structured as a tax-deferred like-
kind exchange under Section 1031 of the Code, in order to defer certain tax
consequences associated with the transfer of the Property to the Company by the
Prentiss Group.

REPAYMENT OF TERMINATION FEE NOTE

  PPL held a note from PCIG which was paid with the proceeds of sales of
properties owned by PCIG. The Company acquired the PGC, 155 Alexandra Way and
Wood Dale 1 & 2 Properties from PCIG and subsequent to the Offering, PPL
received a payment from the seller of approximately $500,000 of the sale
proceeds from those Properties under the note.

SHARING OF OFFICES AND EMPLOYEES

  The Company shares the executive offices and certain employees with the
Manager.  Each company bears its share of costs including allocable portions of
rent, salaries, office expenses, employee benefits and various fixtures and
equipment.  To the extent that services are provided between the companies, such
services are charged at cost plus a mark up of 15%.  The total of these charges
paid by the Company from October 22, 1996 throughout December 31, 1996 totaled
approximately $198 thousand.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Trustees and Shareholders
of Prentiss Properties Trust

  We have audited the accompanying consolidated and combined financial
statements and the financial statement schedule of Prentiss Properties Trust
(the "Company") and the Predecessor Company as listed on page F-1 of this Form
10-K.  These consolidated and combined financial statements and the financial
statement schedule are the responsibility of the Company's management.  Our
responsibility is to express an opinion on these financial statements and
financial statement schedule based on our audits.

  We conducted our audits in accordance with generally accepted auditing
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 consolidated and combined financial statements referred to
above present fairly, in all material respects, the consolidated and combined
financial position of Prentiss Properties Trust as of December 31, 1996 and the
Predecessor Company as of December 31, 1995, and the consolidated and combined
results of operations  and cash flows for the periods October 22, 1996 through
December 31, 1996 and January 1, 1996 through October 21, 1996, and the years
ended December 31, 1995 and 1994, respectively, in conformity with generally
accepted accounting principles. In addition, in our opinion, the financial
statement schedule referred to above, when considered in relation to the basic
financial statements taken as a whole, presents fairly, in all material
respects, the information required to be set forth therein.

(1)   ORGANIZATION AND BASIS OF PRESENTATION

     Prentiss Properties Trust (the "Company") was formed under the laws of the
state of Maryland on July 12, 1996, to be a self-administered and self-managed
real estate investment trust ("REIT").  The Company acquired a sole general
partnership interest in Prentiss Properties Acquisition Partners, L.P. (the
"Operating Partnership") through the Company's wholly-owned subsidiary Prentiss
Properties I, Inc., a Delaware corporation and owns an approximate 86.0% limited
partnership interest in the Operating Partnership.

     The Company has been formed to succeed to substantially all of the
interests of Prentiss Properties Limited, Inc. ("PPL") and its affiliates in (i)
a portfolio of office and industrial properties and (ii) the national
acquisition, property management, leasing, development and construction
businesses of PPL and its affiliates (the "Prentiss Group").  The acquisition,
property management, leasing, development and construction businesses will be
carried out by the Operating Partnership and the Company's majority-owned
affiliates, Prentiss Properties Limited, Inc. and Prentiss Properties Limited
II, Inc. (collectively, the "Manager").

     On October 22, 1996, the Company commenced operations after completing an
initial public offering of 16,000,000 common shares.  The Company issued an
additional 2,400,000 common shares on November 1, 1996 pursuant to the exercise
of the underwriters' over-allotment option.  The combined 18,400,000 common
shares were issued at a price per share of $20.00 (the "Offering").  The Company
used approximately $87.4 million of the net proceeds of the Offering and issued
1,879,897 common shares of the Company for a total consideration of
approximately $125.0 million to purchase certain limited partners' interests in
the Operating Partnership.  The Company contributed the remaining net proceeds
of the Offering to the Operating Partnership.  Subsequent to these transactions,
the Company held an approximate 86.0% interest in the Operating Partnership.

     The Prentiss Group members, who, prior to the Offering, collectively served
as the general partner of the Operating Partnership, contributed to the
Operating Partnership all of its interests in the Properties (as defined below)
and certain management contracts of PPL (the "Contracts") in exchange for
3,295,995 limited partnership units in the Operating Partnership ("Units").

     Upon completion of the Offering and certain related transactions
(collectively, the "Formation Transactions"), the Company owned 87 properties,
28 office and 59 industrial containing 8.9 million net rentable square feet
including 57 properties totaling approximately 6.6 million square feet acquired
from the Predecessor Company (defined below).  Subsequent to the Offering,
through December 31, 1996, the Company acquired eight additional properties,
(collectively, the "Acquired Properties").  The Acquired Properties consist of
five Class "A" suburban office properties totaling approximately 850,000 square
feet and three suburban industrial properties totaling approximately 226,000
square feet.  The office properties are located in the Chicago, Illinois;
Denver, Colorado; and Northern Virginia markets.  The industrial properties are
located in the Chicago, Illinois market.  The purchase price of the Acquired
Properties totaled approximately $116.6 million, which was funded principally
with borrowings under the Line of Credit totaling $72.8 million, other
indebtedness incurred or assumed directly by the Company totaling $35.0 million
and approximately $8.8 million of cash reserves.  As of December 31, 1996, the
Company owned 95 properties, 33 office and 62 industrial (the "Properties")
representing 9.9 million square feet in 12 major markets throughout the U.S.

     The accompanying combined financial statements of the Predecessor Company
include the accounts of Prentiss Properties Acquisition Partners, L.P.; the
operations of Prentiss Properties Limited, Inc.; a 50% equity investment in
Austex Associates L.P. (''Austex''), the accounts of Fairview Eleven Investors
L.P. (''3141 Fairview Park Drive'') from February 23, 1996 through October 21,
1996, the accounts of the Plaza on Bachman Creek from August 19, 1996 through
October 21, 1996; and a 15% equity investment in Park West C2 Associates (''Park
West C2'') from September 5, 1995 through October 21, 1996. The accounts are
presented on a combined basis, as the above properties were under the control of
the Prentiss Group, have common management and were part of the formation of the
Company.  The Predecessor Company's 50% investment in Austex, which held a 50%

   (A) As discussed above, the Predecessor Company had an interest in 57 of the
       Company's properties prior to the formation of the Company.
   (B) In connection with the Formation Transactions, the Company purchased 30
       properties.
   (C) Subsequent to the formation of the Company, through December 31, 1996,
       the Company purchased eight properties.
   (D) The Company holds a non-controlling 49.9% interest in the Broadmoor
       Austin Associates Joint Venture.  The Broadmoor Austin Associates Joint
       Venture owns and operates an office complex in Austin, Texas, consisting
       of seven properties.  The Company accounts for its interest using the
       equity method of accounting.
   (E) Four of the Baltimore industrial properties are owned by three
       partnerships.  The Company holds the majority general partnership
       interest of each of the Partnerships and consolidates the accounts and
       operations of the partnerships.

     With the exception of the Broadmoor Austin properties, all Properties are
majority-owned by the Company and the accounts and operations are consolidated.
The Company owns a 49.9% interest in Broadmoor Austin and accounts for its
interest using the equity method of accounting.  The Company also owns a 95%
non-voting economic interest in the Manager.  The Manager conducts the majority
of the Company's third-party management operations and, due to the non-voting
nature of the Company's ownership interest in the Manager, the Company accounts
for its interest using the equity method of accounting.


(2)   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

 Real Estate

     Real estate and leasehold improvements are stated at the lower of
depreciated cost or net realizable value. In accordance with Statement of
Financial Accounting Standards No. 121, ''Accounting for the Impairment of Long-
Lived Assets and for Long-Lived Assets to Be Disposed of,'' the Operating
Partnership will record impairment losses on long-lived assets used in
operations when events and circumstances indicate that the assets might be
impaired and the estimated undiscounted cash flows to be generated by those
assets are less than the carrying amounts of those assets.  The Company
periodically reviews its properties to determine if its carrying costs will be
recovered from future operating cash flows.  In cases where the Company does not
expect to recover its carrying costs, the Company recognizes an impairment loss.
No such impairment losses have been recognized to date.

     Depreciation on buildings and improvements is provided under the straight-
line method over an estimated useful life of 30 to 50 years for office buildings
and 25 to 30 years for industrial buildings.

     Maintenance and repairs are charged to operations as incurred; major
renewals and betterments are capitalized. When assets are sold or retired, their
costs and related accumulated depreciation are removed from the accounts with
the resulting gains or losses reflected in net income (loss).

 Deferred Charges

     Deferred financing costs are recorded at cost and are being amortized over
the life of the related debt. Leasing commissions and leasehold improvements are
deferred and amortized over the terms of the related leases. Other deferred
charges are amortized over terms applicable to the expenditure.

 Cash and Cash Equivalents

     Cash and cash equivalents consist of cash on hand and investments with
maturities of three months or less when purchased.

 Escrowed Cash

     Escrowed funds as of December 31, 1996 and 1995 are comprised of funds held
for the payment of real estate taxes.

                      NOTES TO CONSOLIDATED AND COMBINED
                             FINANCIAL STATEMENTS 

Income Taxes

  The Company intends to qualify and will elect to be taxed as a REIT under
Sections 856 through 860 of the Internal Revenue Code of 1986, as amended (the
"Code"), commencing with its short taxable year ended December 31, 1996.  If the
Company qualifies for taxation as a REIT, the Company generally will not be
subject to federal corporate income tax on its taxable income that is
distributed to its shareholders.  A REIT is subject to a number of
organizational and operational requirements, including a requirement that it
currently distribute at least 95% of its annual taxable income.  The Predecessor
Company's statements combine the operations and balances of partnerships and an
S-corporation neither of which is directly subject to income tax. The tax effect
of its activities accrues to the individual partners and/or principals of the
respective entity.  The Manager consists of legal entities subject to federal
income tax on their taxable income at regular corporate rates.

Leases

  The Company and Predecessor Company, each as lessor, has retained
substantially all of the risks and benefits of ownership and accounts for its
leases as operating leases.

Revenue Recognition

  Rental income is recognized over the terms of the leases as it is earned.

  Management company income, principally management fees and recoveries of the
Manager, is recognized as earned. Other income consists of (i) development fees,
which are recognized ratably over each project's development period, as defined;
(ii) leasing fees, which are generally recognized upon tenant occupancy of the
leased premises unless such fees are irrevocably due and payable upon lease
execution, in which case recognition occurs on the lease execution date; (iii)
sale fees, which are recognized upon completion of the asset sale; and (iv)
termination fees, which are recognized when earned.

Net Income Per Common Share

  Net income per common share has been computed by dividing net income
applicable to common shareholders by the weighted average number of common
shares outstanding.  For the period from October 22, 1996 through December 31,
1996, the outstanding common share options had an immaterial dilutive effect.

Distributions

   The Company pays regular quarterly distributions which are dependent on
receipt of distributions from the Operating Partnership.

  Earnings and profits, which will determine the taxability of distributions to
shareholders, will differ from income reported for financial reporting purposes
due to the differences for federal tax purposes primarily in the estimated
useful lives used to compute depreciation.  Distributions declared in 1996
represent an approximate 57% return of capital for federal income tax purposes.

Minority Interest

   Minority interest in the Operating Partnership represents the limited
partners' proportionate share of the equity in the Operating Partnership.
Income is allocated to minority interest based on the weighted average
percentage ownership through the year.  Minority interest in partnerships
represents the limited partners' proportionate share of the equity in
partnerships, of which the Operating Partnership has a majority ownership
interest and the accounts of which are consolidated into the Operating
Partnership.

                      NOTES TO CONSOLIDATED AND COMBINED
                             FINANCIAL STATEMENTS 


Concentration of Credit Risk

  The Company places cash deposits at major banks.  Management believes that
through its cash investment policy the credit risk related to these deposits is
minimal.

Distributions of PPL Income

  PPL has retained certain assets and liabilities which were not transferred to
the Operating Partnership pursuant to the formation of the Company. These assets
and liabilities are inconsistent with the Company's investment objectives or are
not continuing businesses. All revenues and expenses related to the management
contracts that were contributed to the Operating Partnership upon formation are
reflected in the accompanying financial statements. The Combined Statements of
Changes in Shareholders' Equity and the Combined Statements of Cash Flows for
the Predecessor Company reflect the distributions of the PPL income, as the
benefit of each period's net income from these contracts has been distributed to
the principals of PPL.

Use of Estimates in the Preparation of Financial Statements

  The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

Fair Value of Financial Instruments

     Statement of Financial Accounting Standards No. 107, "Disclosures About
Fair Value of Financial Instruments," effective for years ending after December
15, 1992, requires disclosures about the fair value of financial instruments
whether or not such instruments are recognizable in the balance sheet.  The
Company's financial instruments include short-term investments, tenant accounts
receivable, accounts payable, other accrued expenses and mortgage loans payable.
The fair values of these financial instruments were not materially different
from their carrying or contract values.

(13)   EMPLOYEE BENEFIT PLAN (IN WHOLE DOLLARS)

  Effective October 16, 1987, the Predecessor Company adopted a 401(k) Savings
Plan (the ''Plan'') for its employees. Under the Plan, as amended, employees,
age 21 and older, are eligible to participate in the Plan after they have
completed one year and 1,000 hours of service.  Upon formation, the Company
adopted the Plan and the terms of the Plan.

  Wages eligible for contribution to the Plan include bonuses, overtime pay and
commissions. Participants who have authorized a pre-tax contribution of 2% or
more may also elect to make an after-tax contribution of up to 8% of their
wages.

  The Plan provides that matching employer contributions are to be determined at
the discretion of the Company.  The Company matches 25% of the first $500
contributed by its employees.  There was no cost to the Company for this
matching for the period October 22, 1996 through December 31, 1996.  The cost to
the Predecessor Company totaled $35,000 for the period January 1, 1996 through
October 21, 1996 and $36,000 and $41,000 for the years ended December 31, 1995
and 1994, respectively.  In addition, the Predecessor Company elected to match
employee contributions with a discretionary match for the year ended December
31, 1994, which totaled $76,000.

  Participants are immediately vested in their pre-tax and after-tax
contributions, the Predecessor Company's matching contributions and earnings
thereon.

  On January 24, 1997, the Company filed a Form S-8 registering 500,000 common
shares in connection with the Company's Share Purchase Plan.  The share purchase
plan enables eligible employees to purchase shares, subject certain
restrictions, of the Company at a 15% discount to fair market value.  No shares
were issued pursuant to the plan during the period October 22, 1996 through
December 31, 1996.

(14)   SHARE INCENTIVE PLAN

  Under the Company's 1996 Share Incentive Plan, the Company granted options in
October 1996 to purchase 1,219,438 common shares at an exercise price of $20.00
per share (the IPO price), in November 1996 to purchase an additional 37,500
shares at an exercise price of $20.625 per share (the then current market price)
and in December 1996 to purchase an additional 395,000 shares at an exercise
price of $23.375 per share (the then current market price).  The options vest
and are exercisable ratably over three and four years.

Share-Based Compensation Plans

  The Company sponsors the Prentiss Properties Trust Trustees' Share
Incentive Plan and the Prentiss Properties Trust 1996 Share Incentive Plan (the
"Plans"), which are share-based incentive compensation plans as described below.
The Company applies APB Opinion 25 and related Interpretations in accounting for
the Plans.  In 1995, the FASB issued Statement of Financial Accounting Standards
Statement No. 123 "Accounting for Stock-Based Compensation ("SFAS 123") which,
if fully adopted by the Company, would change the methods the Company applies in
recognizing the cost of its Plans.  Adoption of the cost recognition provisions
of SFAS 123 is optional and the Company has decided not to elect these
provisions of SFAS 123.  However, pro forma disclosures as if the Company
adopted the cost recognition provisions of SFAS 123 in 1996 are required by SFAS
123 and are presented below.

  Under the Plans, the Company is authorized to issue common shares pursuant
to "Awards" granted in the form of incentive share options (intended to qualify
under Section 422 of the Internal Revenue Code of 1986, as amended) and non-
qualified share options.  Awards may be granted to selected employees and
trustees of the Company or any subsidiary.  In 1996, the Company granted both
incentive share options and non-qualified stock options under the Plans.

Share Options

  Under the 1996 Share Incentive Plan, the Company is authorized to issue up
to 2,030,000 common shares pursuant to "Awards" granted to officers, key
employees and directors in the form of incentive share options qualified under
Section 422 of the Internal Revenue Code of 1986, as amended (the "Code") and
non-qualified share options not qualified under Section 422 of the Code.  These
share options vest ratably over a three or four year period on a graded basis.

  A summary of the status of the Company's share options as of December 31,
1996, and the changes during the period ended on December 31, 1996 is presented
below:

  The fair value of each share option granted is estimated on the date of
grant using the Black-Scholes option-pricing model with the following weighted-
average assumptions for grants in 1996:  dividend yield of 8.00%; different
risk-free interest rates for each grant ranging from 6.05% to 6.26%; options
with expected lives of five years; and volatility of 20% for all grants.

  As of December 31, 1996, there were 1,651,938 options outstanding with a
weighted-average remaining contractual life of 9.83 years and a weighted-average
exercise price of $20.82.  None of these options were exercisable at that time.

  Had the compensation cost for the Company's share-based compensation plans
been determined consistent with SFAS 123, the Company's net income and net
income per common share for 1996 would approximate the pro forma amounts below:

  The effects of applying SFAS 123 in this pro forma disclosure are not
indicative of future amounts.  SFAS 123 does not apply to awards prior to 1995,
and the Company anticipates making awards in the future under its share-based
compensation plans.


(15)  CAPITAL SHARES

  The Board of Trustees is authorized to provide for the issuance of 20,000,000
preferred shares in one or more series, to establish the number of shares in
each series and to fix the designation, powers, preferences, and rights of each
such series and the qualifications, limitations or restrictions thereof.  As of
December 31, 1996 no preferred shares were issued.

  The outstanding Units are redeemable at the option of the holder for a like
number of common shares, or at the option of the Company, the cash equivalent
thereof.  Total Units outstanding at December 31, 1996, were 3,295,995.  The
total market value of these Units at December 31, 1996, based on the last
reported sale price of the common shares on the New York Stock Exchange of
$25.00, was approximately $82.4 million.


(16)   COMMITMENTS AND CONTINGENCIES

Legal Matters

  The Company is subject to various legal proceedings and claims that arise in
the ordinary course of business. These matters are generally covered by
insurance. Management believes that the final outcome of such matters will not
have a material adverse effect on the financial position, results of operations
or liquidity of the Company.

Environmental Matters

  The Company obtained Phase I environmental site assessments ("ESAs") for all
properties involved in the Offering.  The ESAs for the industrial properties
located in Milwaukee, Wisconsin, revealed lead contamination near the property
lines of two of the buildings and the development parcel adjacent to the site.
The ESA states that the contamination is probably the result of unauthorized
dumping of contaminated soil by the owner of a vacant lot located between the
two buildings and the development parcel.  The dumping occurred prior to the
acquisition of the Milwaukee industrials by the Predecessor Company.  Upon
discovery of the unauthorized dumping, the Predecessor Company brought suit
against the owner of the vacant lot, the generators of the contaminated soil and
the prior owner of the properties.  The contaminated soil consists of foundry
sand which was found to contain lead in excess of acceptable trace levels.
According to the ESA, the contamination does not affect the groundwater and is
not likely to migrate or leech into adjoining land.  During 1996, a settlement
to the lawsuit was finalized and was approved by the court.  In accordance with
the Settlement, (i) the Operating Partnership transferred the affected areas ( a
total of approximately 1.2 acres) to the owner of the vacant lot in exchange for
$100,000 and (ii) the owner of the vacant lot and the generators of the
contaminated soil agreed to assume all responsibility for the

remediation of the contaminated soil. The court has entered a finding that the
Operating Partnership was not in the chain of title of the contaminated area. It
is management's opinion that any future outcome of this environmental matter
will not have a material impact on the financial statements.


(17)   PRO FORMA FINANCIAL INFORMATION (UNAUDITED)

  Due to the impact of the Offering, related formation transactions, and the
eight properties acquired subsequent to the Offering, the historical results of
operations are not indicative of future results of operations.  The following
Pro Forma Condensed Statements of Income for the years ended December 31, 1996
and 1995 are presented as if the Offering and related formation transactions and
property acquisitions had occurred at January 1, 1995, and therefore include pro

information and does not purport to present what actual results would have been

                     SECOND AMENDED AND RESTATED AGREEMENT
                            OF LIMITED PARTNERSHIP

                                      OF

                PRENTISS PROPERTIES ACQUISITION PARTNERS, L.P.

                                   RECITALS

     Prentiss Properties Acquisition Partners, L.P. (the "Partnership") was
formed as a limited partnership under the laws of the State of Delaware,
pursuant to an Agreement of Limited Partnership dated as of March 9, 1990 (the
"Original Agreement") and a Certificate of Limited Partnership filed with the
Office of the Secretary of State of the State of Delaware effective as of March
9, 1990.  The Original Agreement was amended and restated in its entirety by an
Amended and Restated Agreement of Limited Partnership dated as of July, 1990,
(the "First Restatement").  Further amended by the First, Second and Third
Amendments to the First Restatement dated as of January 11, 1991, July 13, 1990
and May 20, 1993, respectively.

     The First Restatement is being amended and restated in its entirety to
reflect the transfer of the current limited partners' partnership interests, the
conversion of the current general partner's partnership interest to that of a
limited partner and the admission of a new general partner and several new
limited partners.

                                   AGREEMENT
                                   ---------

     NOW, THEREFORE, in consideration of the foregoing, of mutual covenants
between the parties hereto, and of other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
agree to amend the First Restatement to read in its entirety as follows:

extent not included in clause (ii) above, REIT Expenses; provided, however, that
                                                         --------  -------

of the definition of "Cash Amount."  The names and addresses of the Partners,
number of Partnership Units issued to each Partner, and the Agreed Value of non-
cash Capital Contributions as of the date of contribution is set forth on
Exhibit A.

interest therein).

value of the REIT Shares Amount on the date of receipt by the Company of a
Notice of Exchange.  The value of the REIT Shares Amount shall be based on the
average of the daily market price of REIT Shares for the ten consecutive trading
days immediately preceding the date of such valuation.  The market price for
each such trading day shall be: (i) if the REIT Shares are listed or admitted to
trading on any securities exchange or the NYSE, the sale price, regular way, on
such day, or if no such sale takes place on such day, the average of the closing
bid and asked prices, regular way, on such day, (ii) if the REIT Shares are not

reliable quotation source designated by the Company, or (iii) if the REIT Shares
are not listed or admitted to trading on any securities exchange or the NYSE and
no such last reported sale price or closing bid and asked prices are available,
the average of the reported high bid and low asked prices on such day, as
reported by a reliable quotation source designated by the Company, or if there

the date in question, the value of the REIT Shares shall be determined by the
Company acting in good faith on the basis of such quotations and other
information as it considers, in its reasonable judgment, appropriate.  In the
event the REIT Shares Amount includes rights that a holder of REIT Shares would
be entitled to receive, then the value of such rights shall be determined by the
Company acting in good faith on the basis of such quotations and other
information as it considers, in its reasonable judgment, appropriate.

appropriate public offices within the State of Delaware or such other
jurisdiction to perfect or maintain the Partnership as a limited partnership, to

     "COMPANY" means Prentiss Properties Trust, a Maryland real estate
investment trust.

(i) declares or pays a dividend on its outstanding REIT Shares in REIT Shares or
makes a distribution to all holders of its outstanding REIT Shares in REIT
Shares, (ii) subdivides its outstanding REIT Shares, or (iii) combines its
outstanding REIT Shares into a smaller number of REIT Shares, the Conversion
Factor shall be adjusted by multiplying the Conversion Factor by a fraction, the
numerator of which shall be the number of REIT Shares issued and outstanding on
the record date for such dividend, distribution, subdivision or combination
(assuming for such purposes that such dividend, distribution, subdivision or
combination has occurred as of such time), and the denominator of which shall be
the actual number of REIT Shares (determined without the above assumption)
issued and outstanding on such date.  Any adjustment to the Conversion Factor
shall become effective immediately after the effective date of such event
retroactive to the record date, if any, for such event; provided, however, that
                                                        --------  -------      
if the Company receives a Notice of Exchange after the record date, but prior to
the effective date of such dividend, distribution, subdivision or combination,

issuance or at the time of exercise, and (y) the Company contributes all
proceeds from such issuance, directly or through the General Partner, to the
Partnership. For example, in the event the Company issues REIT Shares for a cash
purchase price and contributes all of the proceeds of such issuance, directly
and through the General Partner, to the Partnership as required hereunder, the
General Partner and the Company, as the Company may so designate, shall be
issued a number of additional Partnership Units equal to the product of (A) the
number of such REIT Shares issued by the Company, the proceeds of which were so
contributed, multiplied by (B) a fraction, the numerator of which is 100%, and
the denominator of which is the Conversion Factor in effect on the date of such
contribution.

          (b) Certain Deemed Contributions of Proceeds of Issuance of REIT
              ------------------------------------------------------------
Shares.  In connection with any and all issuances of REIT Shares, the Company
- ------                                                                       
and the General Partner, as the Company determines, shall make Capital
Contributions to the Partnership of the proceeds therefrom, provided that if the
                                                            -------- ----       
proceeds actually received and contributed by the Company, directly or through
the General Partner, are less than the gross proceeds of such issuance as a
result of any underwriter's discount or other expenses paid or incurred in
connection with such issuance, then the General Partner and the Company shall be
deemed to have made Capital Contributions to the Partnership in the aggregate
amount of the gross proceeds of such issuance and the Partnership shall be
deemed simultaneously to have paid such offering expenses in accordance with
Section 6.05 hereof and in connection with the required issuance of additional
Partnership Units to the General Partner and the Company for such Capital
Contributions pursuant to Section 4.02(a) hereof.

          (c) Minimum Limited Partnership Interest.  In the event that either an
              ------------------------------------                              
exchange pursuant to Section 8.05 hereof or additional Capital Contributions by
the General Partner and the Company would result in the Limited Partners (other
than the Company), in the aggregate, owning less than the Minimum Limited
Partnership Interest, the General Partner and/or the Company and the Limited
Partners shall form another partnership and contribute sufficient Limited
Partnership Interests together with such other Limited Partners so that the
limited partners (other than the Company) of such partnership own at least the
Minimum Limited Partnership Interest.

     4.03 ADDITIONAL FUNDING.  If the General Partner determines that it is in
          ------------------                                                  
the best interests of the Partnership to provide for additional Partnership
funds ("Additional Funds") for any Partnership purpose, the General Partner may
(i) cause the Partnership to obtain such funds from outside borrowings, or (ii)
elect to have the General Partner 

                                      -14-
<PAGE>
 
or the Company provide such Additional Funds to the Partnership through loans or
otherwise.

     4.04 CAPITAL ACCOUNTS.  A separate capital account (a "Capital Account")
          ----------------                                                   
shall be established and maintained for each Partner in accordance with
Regulations Section 1.704-1(b)(2)(iv).  If (i) a new or existing Partner
acquires an additional Partnership Interest in exchange for more than a de
                                                                        --
minimis Capital Contribution, (ii) the Partnership distributes to a Partner more
- -------                                                                         
than a de minimis amount of Partnership property as consideration for a
       -- -------                                                      
Partnership Interest, or (iii) the Partnership is liquidated within the meaning
of Regulation Section 1.704-1(b)(2)(ii)(g), the General Partner shall revalue
the property of the Partnership to its fair market value (as determined by the
General Partner, in its sole discretion, and taking into account Section 7701(g)
of the Code) in accordance with Regulations Section 1.704-1(b)(2)(iv)(f).  When
the Partnership's property is revalued by the General Partner, the Capital
Accounts of the Partners shall be adjusted in accordance with Regulations
Sections 1.704-1(b)(2)(iv)(f) and (g), which generally require such Capital
Accounts to be adjusted to reflect the manner in which the unrealized gain or
loss inherent in such property (that has not been reflected in the Capital
Accounts previously) would be allocated among the Partners pursuant to Section
5.01 if there were a taxable disposition of such property for its fair market
value (as determined by the General Partner, in its sole discretion, and taking
into account Section 7701(g) of the Code) on the date of the revaluation.

     4.05 PERCENTAGE INTERESTS.  If the number of outstanding Partnership Units
          --------------------                                                 
increases or decreases during a taxable year, each Partner's Percentage Interest
shall be adjusted by the General Partner effective as of the effective date of
each such increase or decrease to a percentage equal to the number of
Partnership Units held by such Partner divided by the aggregate number of
Partnership Units outstanding after giving effect to such increase or decrease.
If the Partners' Percentage Interests are adjusted pursuant to this Section
4.05, the Profits and Losses for the taxable year in which the adjustment occurs
shall be allocated between the part of the year ending on the day when the
Partnership's property is revalued by the General Partner and the part of the
year beginning on the following day either (i) as if the taxable year had ended
on the date of the adjustment or (ii) based on the number of days in each part.
The General Partner, in its sole discretion, shall determine which method shall
be used to allocate Profits and Losses for the taxable year in which the
adjustment occurs.  The allocation of Profits and Losses for the earlier part of
the year shall be based on the Percentage Interests before adjustment, and the
allocation of Profits and Losses for the later part shall be based on the
adjusted Percentage Interests.

     4.06 NO INTEREST ON CONTRIBUTIONS.  No Partner shall be entitled to
          ----------------------------                                  
interest on its Capital Contribution.

     4.07 RETURN OF CAPITAL CONTRIBUTIONS.  No Partner shall be entitled to
          -------------------------------                                  
withdraw any part of its Capital Contribution or its Capital Account or to
receive any 

                                      -15-
<PAGE>
 
distribution from the Partnership, except as specifically provided in this
Agreement. Except as otherwise provided herein, there shall be no obligation to
return to any Partner or withdrawn Partner any part of such Partner's Capital
Contribution for so long as the Partnership continues in existence.

     4.08 NO THIRD PARTY BENEFICIARY.  No creditor or other third party having
          --------------------------                                          
dealings with the Partnership shall have the right to enforce the right or
obligation of any Partner to make Capital Contributions or loans or to pursue
any other right or remedy hereunder or at law or in equity, it being understood
and agreed that the provisions of this Agreement shall be solely for the benefit
of, and may be enforced solely by, the parties hereto and their respective
successors and assigns.  None of the rights or obligations of the Partners
herein set forth to make Capital Contributions or loans to the Partnership shall
be deemed an asset of the Partnership for any purpose by any creditor or other
third party, nor may such rights or obligations be sold, transferred or assigned
by the Partnership or pledged or encumbered by the Partnership to secure any
debt or other obligation of the Partnership or of any of the Partners.  In
addition, it is the intent of the parties hereto that no distribution to any
Limited Partner shall be deemed a return of money or other property in violation
of the Act.  However, if any court of competent jurisdiction holds that,
notwithstanding the provisions of this Agreement, any Limited Partner is
obligated to return such money or property, such obligation shall be the
obligation of such Limited Partner and not of the General Partner.  Without
limiting the generality of the foregoing, a deficit Capital Account of a Partner
shall not be deemed to be a liability of such Partner nor an asset or property
of the Partnership.

     5.01 ALLOCATION OF PROFIT AND LOSS.
          ----------------------------- 

          (a)  General.  Profit and Loss of the Partnership for each fiscal year
               -------                                                          
of the Partnership shall be allocated among the Partners in accordance with
their respective Percentage Interests.

          (b)  Minimum Gain Chargeback.  Notwithstanding any provision to the
               -----------------------                                       
contrary, (i) any expense of the Partnership that is a "nonrecourse deduction"
within the meaning of Regulations Section 1.704-2(b)(1) shall be allocated in
accordance with the Partners' respective Percentage Interests, (ii) any expense
of the Partnership that is a "partner nonrecourse deduction" within the meaning
of Regulations Section 1.704-2(i)(2) shall be allocated to the Partner that
bears the "economic risk of loss" of such deduction in accordance with
Regulations Section 1.704-2(i)(1), (iii) if there is a net decrease in
Partnership Minimum Gain within the meaning of Regulations Section

1.704-2(f)(1) for any Partnership taxable year, then, subject to the exceptions
set forth in Regulations Section 1.704-2(f)(2),(3), (4) and (5), items of gain
and income shall be allocated among the Partners in accordance with Regulations
Section 1.704-2(f) and the ordering rules contained in Regulations Section 
1.704-2(j), and (iv) if there is a net decrease in Partner Nonrecourse Debt
Minimum Gain within the meaning of Regulations Section 1.704-2(i)(4) for any
Partnership taxable year, then, subject to the exceptions set forth in
Regulations Section 1.704(2)(g), items of gain and income shall be allocated
among the Partners in accordance with Regulations Section 1.704-2(i)(4) and the
ordering rules contained in Regulations Section 1.704-2(j). A Partner's
"interest in partnership profits" for purposes of determining its share of the
nonrecourse liabilities of the Partnership within the meaning of Regulations
Section 1.752-3(a)(3) shall be such Partner's Percentage Interest. 

          (c)  Qualified Income Offset. If a Partner receives in any taxable
               -----------------------
year an adjustment, allocation, or distribution described in subparagraphs (4),
(5), or (6) of Regulations Section 1.704-1(b)(2)(ii)(d) that causes or increases
a deficit balance in such Partner's Capital Account that exceeds the sum of such
Partner's shares of Partnership Minimum Gain and Partner Nonrecourse Debt
Minimum Gain, as determined in accordance with Regulations Sections 1.704-2(g)
and 1.704-2(i), such Partner shall be allocated specially for such taxable year
(and, if necessary, later taxable years) items of income and gain in an amount
and manner sufficient to eliminate such deficit Capital Account balance as
quickly as possible as provided in Regulations Section 1.704-1(b)(2)(ii)(d).
After the occurrence of an allocation of income or gain to a Partner in
accordance with this Section 5.01(c), to the extent permitted by Regulations
Section 1.704-1(b), items of expense or loss shall be allocated to such Partner
in an amount necessary to offset the income or gain previously allocated to such
Partner under this Section 5.01(c).

          (d)  Capital Account Deficits.  Loss shall not be allocated to a
               ------------------------                                   
Partner to the extent that such allocation would cause a deficit in such
Partner's Capital Account (after reduction to reflect the items described in
Regulations Section 1.704-1(b)(2)(ii)(d)(4), (5) and (6)) to exceed the sum of
such Partner's shares of Partnership Minimum Gain and Partner Nonrecourse Debt
Minimum Gain.  Any Loss in excess of that limitation shall be allocated to the
other Partners in accordance with their respective Percentage Interests.  After
the occurrence of an allocation of Loss to a Partner in accordance with this
Section 5.01(d), to the extent permitted by Regulations Section 1.704-1(b),
Profit shall be allocated to such Partner in an amount necessary to offset the
Loss previously allocated to such Partner under this Section 5.01(d).

          (e)  Allocations Between Transferor and Transferee.  If a Partner
               ---------------------------------------------               
transfers any part or all of its Partnership Interest, the distributive shares
of the various items of Profit and Loss allocable among the Partners during such
fiscal year of the Partnership shall be allocated between the transferor and the
transferee Partner either (i) as if the Partnership's fiscal year had ended on
the date of the transfer, or (ii) based on the 

                                      -17-
<PAGE>
 
number of days of such fiscal year that each was a Partner without regard to the
results of Partnership activities in the respective portions of such fiscal year
in which the transferor and the transferee were Partners. The General Partner,
in its sole discretion, shall determine which method shall be used to allocate
the distributive shares of the various items of Profit and Loss between the
transferor and the transferee Partner.

          (f)  Definition of Profit and Loss.  "Profit" and "Loss" and any items
               -----------------------------                                    
of income, gain, expense, or loss referred to in this Agreement shall be
determined in accordance with federal income tax accounting principles, as
modified by Regulations Section 1.704-1(b)(2)(iv), except that Profit and Loss
shall not include items of income, gain and expense that are specially allocated
pursuant to Section 5.01(b), 5.01(c), or 5.01(d).  All allocations of income,
Profit, gain, Loss, and expense (and all items contained therein) for federal
income tax purposes shall be identical to all allocations of such items set
forth in this Section 5.01, except as otherwise required by Section 704(c) of
the Code and Regulations Section 1.704-1(b)(4).  The General Partner shall have
the authority to elect the method to be used by the Partnership for allocating
items of income, gain, and expense as required by Section 704(c) of the Code and
such election shall be binding on all Partners.

     5.02 DISTRIBUTION OF CASH.
          -------------------- 

          (a) The Partnership shall distribute cash on a quarterly (or, at the
election of the General Partner, more frequent) basis, in an amount determined
by the General Partner in its sole discretion, to the Partners who are Partners
on the Partnership Record Date with respect to such quarter (or other
distribution period) in accordance with their respective Percentage Interests on
the Partnership Record Date; provided, however, that if a new or existing
                             --------  -------                           
Partner acquires an additional Partnership Interest in exchange for a Capital
Contribution on any date other than a Partnership Record Date, the cash
distribution attributable to such additional Partnership Interest relating to
the Partnership Record Date next following the issuance of such additional
Partnership Interest shall be reduced in the proportion to (i) the number of
days that such additional Partnership Interest is held by such Partner bears to
(ii) the number of days between such Partnership Record Date and the immediately
preceding Partnership Record Date.

          (b) Notwithstanding any other provision of this Agreement, the General
Partner is authorized to take any action that it determines to be necessary or
appropriate to cause the Partnership to comply with any withholding requirements
established under the Code or any other federal, state or local law including,
without limitation, pursuant to Sections 1441, 1442, 1445 and 1446 of the Code.
To the extent that the Partnership is required to withhold and pay over to any
taxing authority any amount resulting from the allocation or distribution of
income to the 

                                      -18-
<PAGE>
 
Partner or assignee (including by reason of Section 1446 of the Code), either
(i) if the actual amount to be distributed to the Partner equals or exceeds the
amount required to be withheld by the Partnership, the amount withheld shall be
treated as a distribution of cash in the amount of such withholding to such
Partner, or (ii) if the actual amount to be distributed to the Partner is less
than the amount required to be withheld by the Partnership, the amount required
to be withheld shall be treated as a loan (a "Partnership Loan") from the
Partnership to the Partner on the day the Partnership pays over such amount to a
taxing authority. A Partnership Loan shall be repaid through withholding by the
Partnership with respect to subsequent distributions to the applicable Partner
or assignee. In the event that a Limited Partner (a "Defaulting Limited
Partner") fails to pay any amount owed to the Partnership with respect to the
Partnership Loan within 15 days after demand for payment thereof is made by the
Partnership on the Limited Partner, the General Partner, in its sole discretion,
may elect to make the payment to the Partnership on behalf of such Defaulting
Limited Partner. In such event, on the date of payment, the General Partner
shall be deemed to have extended a loan (a "General Partner Loan") to the
Defaulting Limited Partner in the amount of the payment made by the General
Partner and shall succeed to all rights and remedies of the Partnership against
the Defaulting Limited Partner as to that amount. Without limitation, the
General Partner shall have the right to receive any distributions that otherwise
would be made by the Partnership to the Defaulting Limited Partner until such
time as the General Partner Loan has been paid in full, and any such
distributions so received by the General Partner shall be treated as having been
received by the Defaulting Limited Partner and immediately paid to the General
Partner.

              Any amounts treated as a Partnership Loan or a General Partner
Loan pursuant to this Section 5.02(b) shall bear interest at the lesser of (i)
the base rate on corporate loans at large United States money center commercial
banks, as published from time to time in The Wall Street Journal, or (ii) the
                                         -----------------------             
maximum lawful rate of interest on such obligation, such interest to accrue from
the date the Partnership or the General Partner, as applicable, is deemed to
extend the loan until such loan is repaid in full.

          (c) In no event may a Partner receive a distribution of cash with
respect to a Partnership Unit if such Partner is entitled to receive a cash
dividend as the holder of record of a REIT Share for which all or part of such
Partnership Unit has been or will be exchanged.

     5.03 REIT DISTRIBUTION REQUIREMENTS.  The General Partner shall use its
          ------------------------------                                    
reasonable efforts to cause the Partnership to distribute amounts sufficient to
enable the Company to pay shareholder dividends that will allow the Company to
(i) meet its distribution requirement for qualification as a REIT as set forth
in Section 857 of the Code and (ii) avoid any federal income or excise tax
liability imposed by the Code.

     5.04 NO RIGHT TO DISTRIBUTIONS IN KIND.  No Partner shall be entitled to
          ---------------------------------                                  
demand property other than cash in connection with any distributions by the
Partnership.

     5.05 LIMITATIONS ON RETURN OF CAPITAL CONTRIBUTIONS. Notwithstanding any
          ----------------------------------------------                     
of the provisions of this Article V, no Partner shall have the right to receive
and the General Partner shall not have the right to make, a distribution that
includes a return of all or part of a Partner's Capital Contributions, unless
after giving effect to the return of a Capital Contribution, the sum of all
Partnership liabilities, other than the liabilities to a Partner for the return
of his Capital Contribution, does not exceed the fair market value of the
Partnership's assets.

     5.06 DISTRIBUTIONS UPON LIQUIDATION.  Upon liquidation of the Partnership,
          ------------------------------                                       
after payment of, or adequate provision for, debts and obligations of the
Partnership, including any Partner loans, any remaining assets of the
Partnership shall be distributed to all Partners with positive Capital Accounts
in accordance with their respective positive Capital Account balances.  For
purposes of the preceding sentence, the Capital Account of each Partner shall be
determined after all adjustments made in accordance with Sections 5.01 and 5.02
resulting from Partnership operations and from all sales and dispositions of all
or any part of the Partnership's assets.  To the extent deemed advisable by the
General Partner, appropriate arrangements (including the use of a liquidating
trust) may be made to assure that adequate funds are available to pay any
contingent debts or obligations.

     5.07 SUBSTANTIAL ECONOMIC EFFECT. It is the intent of the Partners that
          ---------------------------                                       
the allocations of Profit and Loss under the Agreement have substantial economic
effect (or be consistent with the Partners' interests in the Partnership in the
case of the allocation of losses attributable to nonrecourse debt) within the
meaning of Section 704(b) of the Code as interpreted by the Regulations
promulgated pursuant thereto.  Article V and other relevant provisions of this
Agreement shall be interpreted in a manner consistent with such intent.

          Interests, or options, rights, warrants or appreciation rights

          or, in turn, subleased in whole or in part to others, for such

          determine, and similarly to prosecute, settle or defend litigation
          with respect to the Partners, the Partnership, or the Partnership's
          assets; provided, however, that the General Partner may not, without
                  --------  -------                                           
          the consent of all of the Partners, confess a judgment against the
          Partnership that is in excess of $20,000 or is not covered by
          insurance;

               (ix)  to file applications, communicate, and otherwise deal with

          way affecting, the Partnership's assets or any other aspect of the

          Partnership by any taxing authority;

          fire and casualty, and any and all other insurance for the protection
          of the Partnership, for the conservation of Partnership assets, or for
          any other purpose convenient or beneficial to the Partnership, in such
          amounts and such types, as it shall determine from time to time;

               (xii)  to determine whether or not to apply any insurance
          proceeds for any property to the restoration of such property or to
          distribute the same;

          estate brokers, and such other persons, as the General Partner
          may deem necessary or appropriate in connection with the Partnership
          business and to pay therefor such reasonable remuneration as the
          General Partner may deem reasonable and proper;

               (xiv)  to retain other services of any kind or nature in

          promptly all federal, state and local income tax returns on behalf of
          the Partnership;

               (xvii)  to distribute Partnership cash or other Partnership
          assets in accordance with this Agreement;

          property to, any further limited or general partnerships, joint
          ventures or other relationships that it deems desirable (including,
          without limitation, the acquisition of interests in, and the

          which it has an equity interest from time to time);

               (xx)  to take such other action, execute, acknowledge, swear to
          or deliver such other documents and instruments, and perform any and
          all other acts that the General Partner deems necessary or appropriate
          for the formation, continuation and conduct of the business and
          affairs of the Partnership (including, without limitation, all actions
          consistent with allowing the Company at all times to qualify as a REIT
          unless the Company voluntarily terminates its REIT status) and to
          possess and enjoy all of the rights and powers of a general partner as
          provided by the Act.

          (b)  Except as otherwise provided herein, to the extent the duties of
the General Partner require expenditures of funds to be paid to third parties,
the General Partner shall not have any obligations hereunder except to the
extent that partnership funds are reasonably available to it for the performance
of such duties, and nothing 

                                      -23-
<PAGE>
 
herein contained shall be deemed to authorize or require the General Partner, in
its capacity as such, to expend its individual funds for payment to third
parties or to undertake any individual liability or obligation on behalf of the
Partnership.

     6.02 DELEGATION OF AUTHORITY.  The General Partner may delegate any or all
          -----------------------                                              
of its powers, rights and obligations hereunder, and may appoint, employ,
contract or otherwise deal with any Person for the transaction of the business
of the Partnership, which Person may, under supervision of the General Partner,
perform any acts or services for the Partnership as the General Partner may
approve.

     6.03 INDEMNIFICATION AND EXCULPATION OF INDEMNITEES.
          ---------------------------------------------- 

          (a)  The Partnership shall indemnify an Indemnitee from and against
any and all losses, claims, damages, liabilities, joint or several, expenses
(including reasonable legal fees and expenses), judgments, fines, settlements,
and other amounts arising from any and all claims, demands, actions, suits or
proceedings, civil, criminal, administrative or investigative, that relate to
the operations of the Partnership as set forth in this Agreement in which any
Indemnitee may be involved, or is threatened to be involved, as a party or
otherwise, unless it is established that:  (i) the act or omission of the
Indemnitee was material to the matter giving rise to the proceeding and either
was committed in bad faith or was the result of active and deliberate
dishonesty; (ii) the Indemnitee actually received an improper personal benefit
in money, property or services; or (iii) in the case of any criminal proceeding,
the Indemnitee had reasonable cause to believe that the act or omission was
unlawful.  The termination of any proceeding by judgment, order or settlement
does not create a presumption that the Indemnitee did not meet the requisite
standard of conduct set forth in this Section 6.03(a).  The termination of any
proceeding by conviction or upon a plea of nolo contendere or its equivalent, or
an entry of an order of probation prior to judgment, creates a rebuttable
presumption that the Indemnitee acted in a manner contrary to that specified in
this Section 6.03(a).  Any indemnification pursuant to this Section 6.03 shall
be made only out of the assets of the Partnership.

          (b)  The Partnership shall reimburse an Indemnitee for reasonable
expenses incurred by an Indemnitee who is a party to a proceeding in advance of
the final disposition of the proceeding upon receipt by the Partnership of (i) a
written affirmation by the Indemnitee of the Indemnitee's good faith belief that
the standard of conduct necessary for indemnification by the Partnership as
authorized in this Section 6.03 has been met, and (ii) a written undertaking by
or on behalf of the Indemnitee to repay the amount if it shall ultimately be
determined that the standard of conduct has not been met.

          (c)  The indemnification provided by this Section 6.03 shall be in
addition to any other rights to which an Indemnitee or any other Person may be
entitled under 

                                      -24-
<PAGE>
 
any agreement, pursuant to any vote of the Partners, as a matter of law or
otherwise, and shall continue as to an Indemnitee who has ceased to serve in
such capacity.

          (d)  The Partnership may purchase and maintain insurance, on behalf of
the Indemnitees and such other Persons as the General Partner shall determine,
against any liability that may be asserted against or expenses that may be
incurred by such Person in connection with the Partnership's activities,
regardless of whether the Partnership would have the power to indemnify such
Person against such liability under the provisions of this Agreement.

          (e)  For purposes of this Section 6.03, the Partnership shall be
deemed to have requested an Indemnitee to serve as fiduciary of an employee
benefit plan whenever the performance by it of its duties to the Partnership
also imposes duties on, or otherwise involves services by, it to the plan or
participants or beneficiaries of the plan; excise taxes assessed on an
Indemnitee with respect to an employee benefit plan pursuant to applicable law
shall constitute fines within the meaning of this Section 6.03; and actions
taken or omitted by the Indemnitee with respect to an employee benefit plan in
the performance of its duties for a purpose reasonably believed by it to be in
the interest of the participants and beneficiaries of the plan shall be deemed
to be for a purpose which is not opposed to the best interests of the
Partnership.

          (f)  In no event may an Indemnitee subject the Limited Partners to
personal liability by reason of the indemnification provisions set forth in this
Agreement.

          (g)  An Indemnitee shall not be denied indemnification in whole or in
part under this Section 6.03 because the Indemnitee had an interest in the
transaction with respect to which the indemnification applies if the transaction
was otherwise permitted by the terms of this Agreement.

          (h)  The provisions of this Section 6.03 are for the benefit of the
Indemnitees, their heirs, successors, assigns and administrators and shall not
be deemed to create any rights for the benefit of any other Persons.

     6.04 LIABILITY OF THE GENERAL PARTNER.
          -------------------------------- 

          (a)  Notwithstanding anything to the contrary set forth in this
Agreement, the General Partner shall not be liable for monetary damages to the
Partnership or any Partners for losses sustained or liabilities incurred as a
result of errors in judgment or of any act or omission if the General Partner
acted in good faith.  The General Partner shall not be in breach of any duty
that the General Partner may owe to the Limited Partners or the Partnership or
any other Persons under this Agreement or of any duty stated or implied by law
or equity provided the General Partner, acting in good faith, abides by the
terms of this Agreement.

                                      -25-
<PAGE>
 
          (b)  The Limited Partners expressly acknowledge that the General
Partner is acting on behalf of the Partnership, the Company and the Company's
shareholders collectively, that the General Partner is under no obligation to
consider the separate interests of the Limited Partners (including, without
limitation, the tax consequences to Limited Partners or the tax consequences of
same, but not all, of the Limited Partners) in deciding whether to cause the
Partnership to take (or decline to take) any actions.  In the event of a
conflict between the interests of the shareholders of the Company on one hand
and the Limited Partners on the other, the General Partner shall endeavor in
good faith to resolve the conflict in a manner not adverse to either the
shareholders of the Company or the Limited Partners; provided, however, that for
so long as the Company, directly or the General Partner owns a controlling
interest in the Partnership, any such conflict that cannot be resolved in a
manner not adverse to either the shareholders of the Company or the Limited
Partners shall be resolved in favor of the shareholders.  The General Partner
shall not be liable for monetary damages for losses sustained, liabilities
incurred, or benefits not derived by Limited Partners in connection with such
decisions, provided that the General Partner has acted in good faith.

          (c)  Subject to its obligations and duties as General Partner set
forth in Section 6.01 hereof, the General Partner may exercise any of the powers
granted to it under this Agreement and perform any of the duties imposed upon it
hereunder either directly or by or through its agents.  The General Partner
shall not be responsible for any misconduct or negligence on the part of any
such agent appointed by it in good faith.

          (d)  Notwithstanding any other provisions of this Agreement or the
Act, any action of the General Partner on behalf of the Partnership or any
decision of the General Partner to refrain from acting on behalf of the
Partnership, undertaken in the good faith belief that such action or omission is
necessary or advisable in order (i) to protect the ability of the Company to
continue to qualify as a REIT or (ii) to prevent the Company from incurring any
taxes under Section 857, Section 4981, or any other provision of the Code, is
expressly authorized under this Agreement and is deemed approved by all of the
Limited Partners.

          (e)  Any amendment, modification or repeal of this Section 6.04 or any
provision hereof shall be prospective only and shall not in any way affect the
limitations on the General Partner's liability to the Partnership and the
Limited Partners under this Section 6.04 as in effect immediately prior to such
amendment, modification or repeal with respect to matters occurring, in whole or
in part, prior to such amendment, modification or repeal, regardless of when
claims relating to such matters may arise or be asserted.

     6.05 REIMBURSEMENT.  The General Partner is hereby authorized to pay
          -------------                                                  
compensation for accounting, administrative, legal, technical, management and
other services rendered to the Partnership.  All of the aforesaid expenditures
(including Administrative Expenses) shall be obligations of the Partnership, and
the General Partner shall be entitled to reimbursement by the Partnership for
any expenditure (including Administrative Expenses) incurred by it on behalf of
the Partnership which shall be made other than out of the funds of the
Partnership.

     6.06 OUTSIDE ACTIVITIES.  Subject to Section 6.08 hereof, the Articles of
          ------------------                                                  
Incorporation and any agreements entered into by the General Partner or its
Affiliates with the Partnership or a Subsidiary, any officer, director,
employee, agent, trustee, Affiliate or shareholder of the General Partner, the
General Partner shall be entitled to and may have business interests and engage
in business activities in addition to those relating to the Partnership,
including business interests and activities substantially similar or identical
to those of the Partnership.  Neither the Partnership nor any of the Limited
Partners shall have any rights by virtue of this Agreement in any such business
ventures, interest or activities.  None of the Limited Partners nor any other
Person shall have any rights by virtue of this Agreement or the partnership
relationship established hereby in any such business ventures, interests or
activities, and the General Partner shall have no obligation pursuant to this
Agreement to offer any interest in any such business ventures, interests and
activities to the Partnership or any Limited Partner, even if such opportunity
is of a character which, if presented to the Partnership or any Limited Partner,
could be taken by such Person.

     6.07 EMPLOYMENT OR RETENTION OF AFFILIATES.
          ------------------------------------- 

          (a)  Any Affiliate of the General Partner may be employed or retained
by the Partnership and may otherwise deal with the Partnership (whether as a
buyer, lessor, lessee, manager, furnisher of goods or services, broker, agent,
lender or otherwise) and may receive from the Partnership any compensation,
price, or other payment therefor which the General Partner determines to be fair
and reasonable.

          (b)  The Partnership may lend or contribute to its Subsidiaries or
other Persons in which it has an equity investment, and such Persons may borrow
funds from the Partnership, on terms and conditions established in the sole and
absolute discretion of the General Partner.  The foregoing authority shall not
create any right or benefit in favor of any Subsidiary or any other Person.

          (c)  The Partnership may transfer assets to joint ventures, other
partnerships, corporations or other business entities in which it is or thereby
becomes a participant upon such terms and subject to such conditions as the
General Partner deems are consistent with this Agreement and applicable law.

                                      -27-
<PAGE>
 
          (d)  Except as expressly permitted by this Agreement, neither the
General Partner nor any of its Affiliates shall sell, transfer or convey any
property to, or purchase any property from, the Partnership, directly or
indirectly, except pursuant to transactions that are on terms that are fair and
reasonable to the Partnership.

     6.08 GENERAL PARTNER PARTICIPATION.  The General Partner agrees that all
          -----------------------------                                      
business activities of the General Partner, including activities pertaining to
the acquisition, development or ownership of office or industrial property or
other property, shall be conducted through the Partnership or one or more
Subsidiary Partnerships; provided, however, that the Company is allowed to make
                         --------  -------                                     
a direct acquisition, but if and only if, such acquisition is made in connection
with the issuance of Additional Securities, which direct acquisition and
issuance have been approved and determined to be in the best interests of the
Company and the Partnership by a majority of the Independent Directors.

     6.09 TITLE TO PARTNERSHIP ASSETS.  Title to Partnership assets, whether
          ---------------------------                                       
real, personal or mixed and whether tangible or intangible, shall be deemed to
be owned by the Partnership as an entity, and no Partner, individually or
collectively, shall have any ownership interest in such Partnership assets or
any portion thereof.  Title to any or all of the Partnership assets may be held
in the name of the Partnership, the General Partner or one or more nominees, as
the General Partner may determine, including Affiliates of the General Partner.
The General Partner hereby declares and warrants that any Partnership assets for
which legal title is held in the name of the General Partner or any nominee or
Affiliate of the General Partner shall be held by the General Partner for the
use and benefit of the Partnership in accordance with the provisions of this
Agreement; provided, however, that the General Partner shall use its best
           --------  -------                                             
efforts to cause beneficial and record title to such assets to be vested in the
Partnership as soon as reasonably practicable.  All Partnership assets shall be
recorded as the property of the Partnership in its books and records,
irrespective of the name in which legal title to such Partnership assets is
held.

     6.10 MISCELLANEOUS.  In the event the Company redeems any REIT Shares,
          -------------                                                    
then the General Partner shall cause the Partnership to purchase from the
General Partner and the Company a number of Partnership Units as determined
based on the application of the Conversion Factor on the same terms that the
Company exchanged such REIT Shares.  Moreover, if the Company makes a cash
tender offer or other offer to acquire REIT Shares, then the General Partner
shall cause the Partnership to make a corresponding offer to the General Partner
and the Company to acquire an equal number of Partnership Units held by the
General Partner and the Company.  In the event any REIT Shares are exchanged by
the Company pursuant to such offer, the Partnership shall redeem an equivalent
number of the General Partner's and the Company Partnership Units for an
equivalent purchase price based on the application of the Conversion Factor.

                                  ARTICLE VII

                          CHANGES IN GENERAL PARTNER
                          --------------------------

     7.01 TRANSFER OF THE GENERAL PARTNER'S PARTNERSHIP INTEREST.
          ------------------------------------------------------ 

          (a)  The General Partner shall not transfer all or any portion of its
General Partnership Interest or withdraw as General Partner except as provided
in Section 7.01(c) or in connection with a transaction described in Section
7.01(d).

          (b)  The General Partner agree that the Percentage Interest for it and
the Company will at all times be in the aggregate, at least a 20%.

          (c)  Except as otherwise provided in Section 6.04(b) or Section
7.01(d) hereof, the Company shall not engage in any merger, consolidation or
other combination with or into another Person or sale of all or substantially
all of its assets, or any reclassification, or any recapitalization or change of
outstanding REIT Shares (other than a change in par value, or from par value to
no par value, or as a result of a subdivision or combination of REIT Shares), in
each case which results in a change of control of the Company (a "Transaction"),
unless as a result of such Transaction all Limited Partners will receive for
each Partnership Unit an amount of cash, securities, or other property equal to
the product of the Conversion Factor and the greatest amount of cash, securities
or other property paid in the Transaction to a holder of one REIT Share in
consideration of one REIT Share, provided that if, in connection with the
                                 -------- ----                           
Transaction, a purchase, tender or exchange offer ("Offer") shall have been made
to and accepted by the holders of more than 50% of the outstanding REIT Shares,
each holder of Partnership Units shall be given the option to exchange its
Partnership Units for the greatest amount of cash, securities, or other property
which a Limited Partner would have received had it (A) exercised its Exchange
Right and (B) sold, tendered or exchanged pursuant to the Offer the REIT Shares
received upon exercise of the Exchange Right immediately prior to the expiration
of the Offer.

          (d)  Notwithstanding Section 7.01(c), the Company or the General
Partner may merge with or into or consolidate with another entity if immediately
after such merger or consolidation (i) substantially all of the assets of the
successor or surviving entity (the "Survivor"), other than Partnership Units
held by the Company or the General Partner, are contributed, directly or
indirectly, to the Partnership as a Capital Contribution in exchange for
Partnership Units with a fair market value equal to the value of the assets so
contributed as determined by the Survivor in good faith and (ii) the Survivor
expressly agrees to assume all obligations of the General Partner or the
Company, as appropriate, hereunder.  Upon such contribution and assumption, the
Survivor shall have the right and duty to amend this Agreement as set forth in
this Section 7.01(d).  The Survivor shall in good faith arrive at a new method
for the calculation of the Cash Amount, the REIT Shares Amount and Conversion
Factor for a 

                                      -29-
<PAGE>
 
Partnership Unit after any such merger or consolidation so as to approximate the
existing method for such calculation as closely as reasonably possible. Such
calculation shall take into account, among other things, the kind and amount of
securities, cash and other property that was receivable upon such merger or
consolidation by a holder of REIT Shares or options, warrants or other rights
relating thereto, and to which a holder of Partnership Units could have acquired
had such Partnership Units been exchanged immediately prior to such merger or
consolidation. Such amendment to this Agreement shall provide for adjustment to
such method of calculation, which shall be as nearly equivalent as may be
practicable to the adjustments provided for with respect to the Conversion
Factor. The Survivor also shall in good faith modify the definition of REIT
Shares and make such amendments to Section 8.05 hereof so as to approximate the
existing rights and obligations set forth in Section 8.05 as closely as
reasonably possible. The above provisions of this Section 7.01(d) shall
similarly apply to successive mergers or consolidations permitted hereunder.

     In respect of any Transaction described in the preceding Paragraph, the
Company is required to use its commercially reasonable efforts to structure such
Transaction to avoid causing the Limited Partners to recognize a gain for
federal income tax purposes by virtue of the occurrence of or their
participation in such Transaction, provided such efforts are consistent with the
exercise of the Board of Trustees' fiduciary duty under applicable law.

     7.02 ADMISSION OF A SUBSTITUTE OR ADDITIONAL GENERAL PARTNER.  A Person
          -------------------------------------------------------           
shall be admitted as a substitute or additional General Partner of the
Partnership only if the following terms and conditions are satisfied:

          (a)  a majority in interest of the Limited Partners (other than the
Company) shall have consented in writing to the admission of the substitute or
additional General Partner, which consent may be withheld in the sole discretion
of such Limited Partners;

          (b)  the Person to be admitted as a substitute or additional General
Partner shall have accepted and agreed to be bound by all the terms and
provisions of this Agreement by executing a counterpart thereof and such other
documents or instruments as may be required or appropriate in order to effect
the admission of such Person as a General Partner, and a certificate evidencing
the admission of such Person as a General Partner shall have been filed for
recordation and all other actions required by Section 2.05 hereof in connection
with such admission shall have been performed;

          (c)  if the Person to be admitted as a substitute or additional
General Partner is a corporation or a partnership it shall have provided the
Partnership with evidence satisfactory to counsel for the Partnership of such
Person's authority to 

                                      -30-
<PAGE>
 
become a General Partner and to be bound by the terms and provisions of this
Agreement; and

          (d)  counsel for the Partnership shall have rendered an opinion
(relying on such opinions from other counsel and the state or any other
jurisdiction as may be necessary) that the admission of the person to be
admitted as a substitute or additional General Partner is in conformity with the
Act, that none of the actions taken in connection with the admission of such
Person as a substitute or additional General Partner will cause (i) the
Partnership to be classified other than as a partnership for federal income tax
purposes, or (ii) the loss of any Limited Partner's limited liability.

     7.03 EFFECT OF BANKRUPTCY, WITHDRAWAL, DEATH OR DISSOLUTION  OF A GENERAL
          --------------------------------------------------------------------
PARTNER.
- ------- 

          (a)  Upon the occurrence of an Event of Bankruptcy as to a General
Partner (and its removal pursuant to Section 7.04(a) hereof) or the death,
withdrawal, removal or dissolution of a General Partner (except that, if a
General Partner is on the date of such occurrence a partnership, the withdrawal,
death, dissolution, Event of Bankruptcy as to, or removal of a partner in, such
partnership shall be deemed not to be a dissolution of such General Partner if
the business of such General Partner is continued by the remaining partner or
partners), the Partnership shall be dissolved and terminated unless the
Partnership is continued pursuant to Section 7.03(b) hereof.

          (b)  Following the occurrence of an Event of Bankruptcy as to a
General Partner (and its removal pursuant to Section 7.04(a) hereof) or the
death, withdrawal, removal or dissolution of a General Partner (except that, if
a General Partner is on the date of such occurrence a partnership, the
withdrawal, death, dissolution, Event of Bankruptcy as to, or removal of a
partner in, such partnership shall be deemed not to be a dissolution of such
General Partner if the business of such General Partner is continued by the
remaining partner or partners), the Limited Partners, within 90 days after such
occurrence, may elect to reconstitute the Partnership and continue the business
of the Partnership for the balance of the term specified in Section 2.04 hereof
by selecting, subject to Section 7.02 hereof and any other provisions of this
Agreement, a substitute General Partner by unanimous consent of the Limited
Partners.  If the Limited Partners elect to reconstitute the Partnership and
admit a substitute General Partner, the relationship with the Partners and of
any Person who has acquired an interest of a Partner in the Partnership shall be
governed by this Agreement.

     7.04 REMOVAL OF A GENERAL PARTNER.
          ---------------------------- 

          (a)  Upon the occurrence of an Event of Bankruptcy as to, or the
dissolution of, a General Partner, such General Partner shall be deemed to be
removed automatically; provided, however, that if a General Partner is on the
                       --------  -------                                     
date of such 

                                      -31-

occurrence a partnership, the withdrawal, death, dissolution, Event of
Bankruptcy as to or removal of a partner in such partnership shall be deemed not
to be a dissolution of the General Partner if the business of such General
Partner is continued by the remaining partner or partners.

          (b)  If a General Partner has been removed pursuant to this Section
7.04 and the Partnership is continued pursuant to Section 7.03 hereof, such
General Partner shall promptly transfer and assign its General Partnership
Interest in the Partnership to the substitute General Partner approved by a
majority in interest of the Limited Partners in accordance with Section 7.03(b)
hereof and otherwise admitted to the Partnership in accordance with Section 7.02
hereof.  At the time of assignment, the removed General Partner shall be
entitled to receive from the substitute General Partner the fair market value of
the General Partnership Interest of such removed General Partner as reduced by
any damages caused to the Partnership by such General Partner.  Such fair market
value shall be determined by an appraiser mutually agreed upon by the General
Partner and a majority in interest of the Limited Partners within 10 days
following the removal of the General Partner.  In the event that the parties are
unable to agree upon an appraiser, the removed General Partner and a majority in
interest of the Limited Partners each shall select an appraiser.  Each such
appraiser shall complete an appraisal of the fair market value of the removed
General Partner's General Partnership Interest within 30 days of the General
Partner's removal, and the fair market value of the removed General Partner's
General Partnership Interest shall be the average of the two appraisals;
provided, however, that if the higher appraisal exceeds the lower appraisal by
- --------  -------                                                             
more than 20% of the amount of the lower appraisal, the two appraisers, no later
than 40 days after the removal of the General Partner, shall select a third
appraiser who shall complete an appraisal of the fair market value of the
removed General Partner's General Partnership Interest no later than 60 days
after the removal of the General Partner.  In such case, the fair market value
of the removed General Partner's General Partnership Interest shall be the
average of the two appraisals closest in value.

          (c)  The General Partnership Interest of a removed General Partner,
during the time after default until transfer under Section 7.04(b), shall be
converted to that of a special Limited Partner; provided, however, such removed
                                                --------  -------              
General Partner shall not have any rights to participate in the management and
affairs of the Partnership, and shall not be entitled to any portion of the
income, expense, profit, gain or loss allocations or cash distributions
allocable or payable, as the case may be, to the Limited Partners.  Instead,
such removed General Partner shall receive and be entitled only to retain
distributions or allocations of such items that it would have been entitled to
receive in its capacity as General Partner, until the transfer is effective
pursuant to Section 7.04(b).

          (d)  All Partners shall have given and hereby do give such consents,
shall take such actions and shall execute such documents as shall be legally
necessary and sufficient to effect all the foregoing provisions of this Section.


                                 ARTICLE VIII

                            RIGHTS AND OBLIGATIONS
                            OF THE LIMITED PARTNERS
                            -----------------------

     8.01 MANAGEMENT OF THE PARTNERSHIP.  The Limited Partners shall not
          -----------------------------                                 
participate in the management or control of Partnership business nor shall they
transact any business for the Partnership, nor shall they have the power to sign
for or bind the Partnership, such powers being vested solely and exclusively in
the General Partner.

     8.02 POWER OF ATTORNEY. Each Limited Partner hereby irrevocably appoints
          -----------------                                                  
the General Partner its true and lawful attorney-in-fact, who may act for each
Limited Partner and in its name, place and stead, and for its use and benefit,
to sign, acknowledge, swear to, deliver, file and record, at the appropriate
public offices, any and all documents, certificates, and instruments as may be
deemed necessary or desirable by the General Partner to carry out fully the
provisions of this Agreement and the Act in accordance with their terms, which
power of attorney is coupled with an interest and shall survive the death,
dissolution or legal incapacity of the Limited Partner, or the transfer by the
Limited Partner of any part or all of its Partnership Interest.

     8.03 LIMITATION ON LIABILITY OF LIMITED PARTNERS. No Limited Partner shall
          -------------------------------------------                          
be liable for any debts, liabilities, contracts or obligations of the
Partnership.  A Limited Partner shall be liable to the Partnership only to make
payments of its Capital Contribution, if any, as and when due hereunder.  After
its Capital Contribution is fully paid, no Limited Partner shall, except as
otherwise required by the Act, be required to make any further Capital
Contributions or other payments or lend any funds to the Partnership.

     8.04 OWNERSHIP BY LIMITED PARTNER OF CORPORATE GENERAL PARTNER OR 
          ------------------------------------------------------------
AFFILIATE.  No Limited Partner shall at any time, either directly or indirectly,
- ---------
own any stock or other interest in the General Partner or in any Affiliate
thereof, if such ownership by itself or in conjunction with other stock or other
interests owned by other Limited Partners would, in the opinion of counsel for
the Partnership, jeopardize the classification of the Partnership as a
partnership for federal income tax purposes. The General Partner shall be
entitled to make such reasonable inquiry of the Limited Partners as is required
to establish compliance by the Limited Partners with the provisions of this
Section.

                                      -33-

     8.05 EXCHANGE RIGHT.
          -------------- 

          (a)  Subject to Sections 8.05(b), 8.05(c), 8.05(d), 8.05(e) and
8.05(f), on or after the date which is one year after the closing of the
Offering, each Limited Partner, other than the Company, shall have the right
(the "Exchange Right") to require the Partnership to redeem on a Specified
Exchange Date all or a portion of the Partnership Units held by such Limited
Partner at an exchange price equal to and in the form of the Cash Amount to be
paid by the Partnership.  The Exchange Right shall be exercised pursuant to a
Notice of Exchange delivered to the Partnership (with a copy to the General
Partner) by the Limited Partner who is exercising the Exchange Right (the
"Exchanging Partner"); provided, however, that the Partnership shall not be
obligated to satisfy such Exchange Right if the Company and/or the General
Partner elects to purchase the Partnership Units subject to the Notice of
Exchange pursuant to Section 8.05(b); and provided, further, that no Limited
Partner may deliver more than two Notices of Exchange during each calendar year.
A Limited Partner may not exercise the Exchange Right for less than 1,000
Partnership Units or, if such Limited Partner holds less than 1,000 Partnership
Units, all of the Partnership Units held by such Partner.  The Exchanging
Partner shall have no right, with respect to any Partnership Units so exchanged,
to receive any distribution paid with respect to Partnership Units if the record
date for such distribution is on or after the Specified Exchange Date.

          (b)  Notwithstanding the provisions of Section 8.05(a), a Limited
Partner that exercises the Exchange Right shall be deemed to have offered to
sell the Partnership Units described in the Notice of Exchange to the General
Partner and the Company, and either of the General Partner or the Company (or
both) may, in its sole and absolute discretion, elect to purchase directly and
acquire such Partnership Units by paying to the Exchanging Partner either the
Cash Amount or the REIT Shares Amount, as elected by the General Partner or the
Company (in its sole and absolute discretion), on the Specified Exchange Date,
whereupon the General Partner or the Company shall acquire the Partnership Units
offered for exchange by the exchanging Partner and shall be treated for all
purposes of this Agreement as the owner of such Partnership Units.  If the
General Partner and/or the Company shall elect to exercise its right to purchase
Partnership Units under this Section 8.05(b) with respect to a Notice of
Exchange, they shall so notify the Exchanging Partner within five Business Days
after the receipt by the General Partner of such Notice of Exchange.  Unless the
General Partner and/or the Company (in its sole and absolute discretion) shall
exercise its right to purchase Partnership Units from the Exchanging Partner
pursuant to this Section 8.05(b), neither the General Partner nor the Company
shall have any obligation to the Exchanging Partner or the Partnership with
respect to the Exchanging Partner's exercise of the Exchange Right.  In the
event the General Partner or the Company shall exercise its right to purchase
Partnership Units with respect to the exercise of a Exchange Right in the manner
described in the first sentence of this Section 8.05(b), the Partnership shall
have no obligation to pay any amount to the Exchanging Partner 

                                      -34-
<PAGE>
 
with respect to such Exchanging Partner's exercise of such Exchange Right, and
each of the Exchanging Partner, the Partnership, and the General Partner or the
Company, as the case may be, shall treat the transaction between the General
Partner or the Company, as the case may be, and the Exchanging Partner for
federal income tax purposes as a sale of the Exchanging Partner's Partnership
Units to the General Partner or the Company, as the case may be. Each Exchanging
Partner agrees to execute such documents as the General Partner may reasonably
require in connection with the issuance of REIT Shares upon exercise of the
Exchange Right.

          (c)  Notwithstanding the provisions of Section 8.05(a) and 8.05(b), a
Limited Partner shall not be entitled to exercise the Exchange Right if the
delivery of REIT Shares to such Partner on the Specified Exchange Date by the
General Partner or the Company pursuant to Section 8.05(b) (regardless of
whether or not the General Partner or the Company would in fact exercise its
rights under Section 8.05(b)) would (i) result in such Partner or any other
person owning, directly or indirectly, REIT Shares in excess of the Ownership
Limitation (as defined in the Articles of Incorporation) and calculated in
accordance therewith, except as provided in the Articles of Incorporation, (ii)
result in REIT Shares being owned by fewer than 100 persons (determined without
reference to any rules of attribution), except as provided in the Articles of
Incorporation, (iii) result in the Company being "closely held" within the
meaning of Section 856(h) of the Code, (iv) cause the Company to own, directly
or constructively, 10% or more of the ownership interests in a tenant of the
General Partner's, the Partnership's, or a Subsidiary Partnership's, real
property, within the meaning of Section 856(d)(2)(B) of the Code, or (v) cause
the acquisition of REIT Shares by such Partner to be "integrated" with any other
distribution of REIT Shares for purposes of complying with the registration
provisions of the Securities Act of 1933, as amended (the "Securities Act").
The General Partner or the Company, in their sole discretion, may waive the
restriction on exchange set forth in this Section 8.05(c); provided, however,
                                                           --------  ------- 
that in the event such restriction is waived, the Exchanging Partner shall be
paid the Cash Amount.

          (d)  Any Cash Amount to be paid to an Exchanging Partner pursuant to
this Section 8.05 shall be paid on the Specified Exchange Date; provided,
                                                                -------- 
however, that the Company or the General Partner may elect to cause the
- -------                                                                
Specified Exchange Date to be delayed for up to an additional 180 days to the
extent required for the Company to cause additional REIT Shares to be issued to
provide financing to be used to make such payment of the Cash Amount.
Notwithstanding the foregoing, the Company and the General Partner agree to use
their best efforts to cause the closing of the acquisition of exchanged
Partnership Units hereunder to occur as quickly as reasonably possible.

          (e)  Notwithstanding any other provision of this Agreement, the
General Partner shall place appropriate restrictions on the ability of the
Limited Partners to exercise their Exchange Rights as and if deemed necessary to
ensure that the 

                                      -35-
<PAGE>
 
Partnership does not constitute a "publicly traded partnership" under section
7704 of the Code. If and when the General Partner determines that imposing such
restrictions is necessary, the General Partner shall give prompt written notice
thereof (a "Restriction Notice") to each of the Limited Partners, which notice
shall be accompanied by a copy of an opinion of counsel to the Partnership which
states that, in the opinion of such counsel, restrictions are necessary in order
to avoid the Partnership being treated as a "publicly traded partnership" under
section 7704 of the Code.

     8.06 REGISTRATION.
          ------------ 

          (a) Shelf Registration of the Common Stock.  Prior to or on the first
              --------------------------------------                           
date upon which the Partnership Units owned by any Limited Partner may be
exchanged (or such other date as may be required under applicable provisions of
the Securities Act), the Company agrees to file with the Securities and Exchange
Commission (the "Commission"), a shelf registration statement on Form S-3 under
Rule 415 of the Securities Act (a "Registration Statement"), or any similar rule
that may be adopted by the Commission, with respect to all of the shares of
Common Stock that may be issued upon exchange of such Partnership Units pursuant
to Section 8.05 hereof ("Exchange Shares").  The Company will use its best
efforts to have the Registration Statement declared effective under the
Securities Act.  The Company need not file a separate Registration Statement,
but may file one Registration Statement covering Exchange Shares issuable to
more than one Limited Partner.  The Company further agrees to supplement or make
amendments to each Registration Statement, if required by the rules, regulations
or instructions applicable to the registration form utilized by the Company or
by the Securities Act or rules and regulations thereunder for such Registration
Statement.

          (b) If a Registration Statement under subsection (a) above is not
available under the securities laws or the rules of the Commission, or if
required to permit the resale of Exchange Shares by "Affiliates" (as defined in
the Securities Act), the Company agrees to file with the Commission a
Registration Statement covering the resale of Exchange Shares by Affiliates or
others whose Exchange Shares are not covered by a Registration Statement filed
pursuant to subsection (a) above.  The Company will use its best efforts to have
the Registration Statement declared effective under the Securities Act.  The
Company need not file a separate Registration Statement, but may file one
Registration Statement covering Exchange Shares issuable to more than one
Limited Partner.  The Company further agrees to supplement or make amendments to
each Registration Statement, if required by the rules, regulations or
instructions applicable to the registration form utilized by the Company or by
the Securities Act or rules and regulations thereunder for such Registration
Statement.

          (c) Listing on Securities Exchange.  If the Company shall list or
              ------------------------------                               
maintain the listing of any shares of Common Stock on any securities exchange or

                                      -36-

national market system, it will at its expense and as necessary to permit the
registration and sale of the Exchange Shares hereunder, list thereon, maintain
and, when necessary, increase such listing to include such Exchange Shares.

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

     9.01 PURCHASE FOR INVESTMENT.
          ----------------------- 

          (a)  Each Limited Partner hereby represents and warrants to the
General Partner, to the Company and to the Partnership that the acquisition of
his Partnership Interests is made as a principal for his account for investment
purposes only and not with a view to the resale or distribution of such
Partnership Interest.

          (b)  Each Limited Partner agrees that he will not sell, assign or
otherwise transfer his Partnership Interest or any fraction thereof, whether
voluntarily or by operation of law or at judicial sale or otherwise, to any
Person who does not make the representations and warranties to the General
Partner set forth in Section 9.01(a) above and similarly agree not to sell,
assign or transfer such Partnership Interest or fraction thereof to any Person
who does not similarly represent, warrant and agree.

     9.02 RESTRICTIONS ON TRANSFER OF LIMITED PARTNERSHIP INTERESTS.
          --------------------------------------------------------- 

          (a)  Subject to the provisions of 9.02(b), (c) and (d), no Limited
Partner may offer, sell, assign, hypothecate, pledge or otherwise transfer all
or any portion of his Limited Partnership Interest, or any of such Limited
Partner's economic rights as a Limited Partner, whether voluntarily or by
operation of law or at judicial sale or otherwise (collectively, a "Transfer")
without the consent of the General Partner, which consent may be granted or
withheld in its sole and absolute discretion.  Any such purported transfer
undertaken without such consent shall be considered to be null and void ab
initio and shall not be given effect.  Each Limited Partner acknowledges that
the General Partner has agreed not to grant any such consent prior to the
Transfer Restriction Date.  The General Partner may require, as a condition of
any Transfer to which it consents, that the transferor assume all costs incurred
by the Partnership in connection therewith.

          (b)  No Limited Partner may withdraw from the Partnership other than
as a result of a permitted Transfer (i.e., a Transfer consented to as
                                     ----                            
contemplated by clause (a) above or clause (c) below or a Transfer pursuant to
9.05 below) of all of his Partnership Units pursuant to this Article IX or
pursuant to an exchange of all of his Partnership Units pursuant to 8.05.  Upon
the permitted Transfer or redemption of all of 

                                      -37-
<PAGE>
 
a Limited Partner's Partnership Units, such Limited Partner shall cease to be a
Limited Partner.

          (c)  Subject to 9.02(d), (e) and (f) below, a Limited Partner may
Transfer, with the consent of the General Partner, all or a portion of his
Partnership Units to (i) a parent or parent's spouse, natural or adopted
descendant or descendants, spouse of such descendant, or brother or sister, or a
trust created by such Limited Partner for the benefit of such Limited Partner
and/or any such person(s), of which trust such Limited Partner or any such
person(s) is a trustee, (ii) a corporation controlled by a Person or Persons
named in (i) above, or (ii) if the Limited Partner is an entity, its beneficial
owners.

          (d)  No Limited Partner may effect a Transfer of its Limited
Partnership Interest, in whole or in part, if, in the opinion of legal counsel
for the Partnership, such proposed Transfer would require the registration of
the Limited Partnership Interest under the Securities Act of 1933, as amended,
or would otherwise violate any applicable federal or state securities or blue
sky law (including investment suitability standards).

          (e)  No Transfer by a Limited Partner of its Partnership Units, in
whole or in part, may be made to any Person if (i) in the opinion of legal
counsel for the Partnership, the transfer would result in the Partnership's
being treated as an association taxable as a corporation (other than a qualified
REIT subsidiary within the meaning of Section 856(i) of the Code), (ii) in the
opinion of legal counsel for the Partnership, it would adversely affect the
ability of the Company to continue to qualify as a REIT or subject the Company
to any additional taxes under Section 857 or Section 4981 of the Code, or (iii)
such transfer is effectuated through an "established securities market" or a
"secondary market (or the substantial equivalent thereof)" within the meaning of
Section 7704 of the Code.

          (f)  No transfer of any Partnership Units may be made to a lender to
the Partnership or any Person who is related (within the meaning of Regulations
Section 1.752-4(b)) to any lender to the Partnership whose loan constitutes a
nonrecourse liability (within the meaning of Regulations Section 1.752-1(a)(2)),
without the consent of the General Partner, which may be withheld in its sole
and absolute discretion, provided that as a condition to such consent the lender
                         -------- ----                                          
will be required to enter into an arrangement with the Partnership and the
General Partner to exchange or redeem for the Cash Amount any Partnership Units
in which a security interest is held simultaneously with the time at which such
lender would be deemed to be a partner in the Partnership for purposes of
allocating liabilities to such lender under Section 752 of the Code.

                                      -38-
<PAGE>
 
          (g)  Any Transfer in contravention of any of the provisions of this
Article IX shall be void and ineffectual and shall not be binding upon, or
recognized by, the Partnership.

          (h)  Prior to the consummation of any Transfer under this Article IX,
the transferor and/or the transferee shall deliver to the General Partner such
opinions, certificates and other documents as the General Partner shall request
in connection with such Transfer.

     9.03 ADMISSION OF SUBSTITUTE LIMITED PARTNER.
          --------------------------------------- 

          (a)  Subject to the other provisions of this Article IX, an assignee

          documents or instruments as the General Partner may require in order
          to effect the admission of such Person as a Limited Partner.

                  (ii) To the extent required, an amended Certificate evidencing
          the admission of such Person as a Limited Partner shall have been
          signed, acknowledged and filed for record in accordance with the Act.

<PAGE>
 
                  (vii)  The assignee has obtained the prior written consent of
          the General Partner to its admission as a Substitute Limited Partner,
          which consent may be given or denied in the exercise of the General
          Partner's sole and absolute discretion.

          (b)  For the purpose of allocating Profits and Losses and distributing
cash received by the Partnership, a Substitute Limited Partner shall be treated

          (b)  Any Person who is the assignee of all or any portion of a Limited
Partner's Limited Partnership Interest, but does not become a Substitute Limited
Partner and desires to make a further assignment of such Limited Partnership
Interest, shall be subject to all the provisions of this Article IX to the same
extent and in the same manner as any Limited Partner desiring to make an
assignment of its Limited Partnership Interest.

     9.05 EFFECT OF BANKRUPTCY, DEATH, INCOMPETENCE OR TERMINATION OF A LIMITED

PARTNER.  The occurrence of an Event of Bankruptcy as to a Limited Partner, the
- -------                                                                        
death of a Limited Partner or a final adjudication that a Limited Partner is
incompetent (which term shall include, but not be limited to, insanity) shall
not cause the termination or dissolution of the Partnership, and the business of
the Partnership shall continue if an order for relief in a bankruptcy proceeding
is entered against a Limited Partner, the trustee or receiver of his estate or,
if he dies, his executor, administrator or trustee, or, if he is finally
adjudicated incompetent, his committee, guardian or conservator, shall have the
rights of such Limited Partner for the purpose of settling or managing his
estate property and such power as the bankrupt, deceased or incompetent Limited
Partner possessed to assign all or any part of his Partnership

Interest and to join with the assignee in satisfying conditions precedent to the
admission of the assignee as a Substitute Limited Partner.

     9.06 JOINT OWNERSHIP OF INTERESTS.  A Partnership Interest may be acquired
          ----------------------------                                         
by two individuals as joint tenants with right of survivorship, provided that
such individuals either are married or are related and share the same home as
tenants in common.  The written consent or vote of both owners of any such
jointly held Partnership Interest shall be required to constitute the action of
the owners of such Partnership Interest; provided, however, that the written
                                         --------  -------                  
consent of only one joint owner will be required if the Partnership has been
provided with evidence satisfactory to the counsel for the Partnership that the
actions of a single joint owner can bind both owners under the applicable laws
of the state of residence of such joint owners.  Upon the death of one owner of
a Partnership Interest held in a joint tenancy with a right of survivorship, the
Partnership Interest shall become owned solely by the survivor as a Limited
Partner and not as an assignee.  The Partnership need not recognize the death of
one of the owners of a jointly-held Partnership Interest until it shall have
received notice of such death.  Upon notice to the General Partner from either
owner, the General Partner shall cause the Partnership Interest to be divided
into two equal Partnership Interests, which shall thereafter be owned separately
by each of the former owners.

SECTION 2 COMMITMENT.

     2.1 REVOLVING FACILITY.  Subject to the provisions in the Loan Documents,
each Lender severally and not jointly agrees to lend to Borrower one or more
Borrowings hereunder which Borrower may borrow, repay and reborrow under this
Agreement, subject to the following conditions:

     (a) each Borrowing requested by Borrower hereunder must occur on a Business
Day and no later than the Business Day immediately preceding the Termination
Date;

     (b) each Borrowing requested by Borrower must be in an amount not less than
$1,000,000.00 or a greater integral multiple of $100,000.00 or, if less, the
Unused Commitment;

     (c) the Total Principal Debt may not exceed the lesser of (i) the Total
Commitment, and (ii) the Borrowing Base; and

     (d) no Lender's Principal Debt may exceed such Lender's Commitment.

     2.2 BORROWING PROCEDURE.  The following procedures apply to Borrowings:

     (a) Borrower may request a Borrowing by submitting to the Administrative
Agent a Borrowing Request.  The Borrowing Request must be received by the
Administrative Agent no later than 11:00 a.m. on (i) the third (3rd) Business
Day preceding the Borrowing Date for any Eurodollar Borrowing, or (ii) the
Business Day preceding the Borrowing Date for any Base Rate Borrowing.  The
Administrative Agent shall promptly notify each Lender of its receipt of any
Borrowing Request and its contents.  A Borrowing Request is irrevocable and
binding on Borrower.

     (b) By 11:00 a.m. on the applicable Borrowing Date, each Lender shall remit
its Pro Rata Part of each requested Borrowing by wire transfer to the
Administrative Agent pursuant to the Administrative Agent's wire transfer
instructions on SCHEDULE 1 (or as otherwise directed by the Administrative
Agent) in funds that are available for immediate use by the Administrative
Agent. Subject to receipt of such funds, the Administrative Agent shall make
such funds available to Borrower in Dallas, Texas at 12:00 noon on such
Borrowing Date (unless it has actual knowledge that any applicable condition
precedent has not been satisfied by Borrower).

     (c) Absent contrary written notice from a Lender, the Administrative Agent
may assume that each Lender has made its Pro Rata Part of the requested
Borrowing available to the Administrative Agent on the applicable Borrowing
Date, and the Administrative Agent may, in reliance upon such assumption (but is
not required to), make available to Borrower a corresponding amount.  If a
Lender fails to make its Pro Rata Part of any requested Borrowing available to
the Administrative Agent on the applicable Borrowing Date, the 

                                       12
<PAGE>
 
Administrative Agent may recover the applicable amount on demand (i) from such
Lender, together with interest at the Federal Funds Rate for the period
commencing on the date the amount was made available to Borrower by the
Administrative Agent and ending on (but excluding) the date the Administrative
Agent recovers the amount from such Lender, or (ii) if such Lender fails to pay
its amount upon the Administrative Agent's demand, then from Borrower, together
with interest at an annual interest rate equal to the rate applicable to the
requested Borrowing for the period commencing on the Borrowing Date and ending
on (but excluding) the date the Administrative Agent recovers the amount from
Borrower. No Lender is responsible for the failure of any other Lender to make
its Pro Rata Part of any Borrowing.

     2.3 TERMINATION.  Without premium or penalty, and upon giving at least
three (3) Business Days prior written and irrevocable notice to the
Administrative Agent, Borrower may terminate all or part of the unused portion
of the Total Commitment.  Each partial termination must be in an amount of not
less than $1,000,000.00 or a greater integral multiple thereof, and shall be Pro
Rata among all of the Lenders.  Once terminated, the Total Commitment may not be
increased or reinstated.

     2.4 BORROWING BASE.

     (a) ADMISSION OF PROJECTS INTO THE BORROWING BASE.

         (i) Borrower shall provide the Administrative Agent (with copies for
     each of the Lenders) with a written request for a Property to be admitted
     into the Borrowing Base. Such request shall be accompanied by information
     regarding the Property (including, without limitation, a property
     description, purchase information (including any contracts of sale and
     closing statements), one (1) original and two (2) copies of a recent survey
     with appropriate certifications to the Administrative Agent, for the
     benefit of the Lenders, and one (1) copy for each of the other Lenders,
     recent appraisals (commissioned by and addressed to the Administrative
     Agent, for the benefit of the Lenders), rent rolls, operating statements,
     environmental assessments, condition reports, roof reports, and other such
     information requested by the Administrative Agent as shall be necessary in
     order for the Administrative Agent and the Required Lenders to determine
     whether such Property is an Eligible Project.

         (ii) In order for a Property to be eligible for inclusion in the
     Borrowing Base (an "ELIGIBLE PROJECT"), such Property shall have
     characteristics consistent with the following general guidelines:

         project or office project;

              (B) Borrower shall have good and indefeasible title to such
         Property, free and clear of all Liens (except for Permitted Liens); and

              (C) all leases covering such Property shall be acceptable to the
         Administrative Agent.

     Notwithstanding the foregoing guidelines, the Required Lenders shall have
     the right to exclude a Property that is otherwise an Eligible Project from
     the Borrowing Base, if the Required Lenders, in their sole discretion,
     determine that such Property is not eligible for inclusion in the Borrowing
     Base.

         (iii)  Each Property shall be subject to the Required Lenders' approval
     for admission to the Borrowing Base after evaluation of such Property's
     market area, location, access, and design.

                                       13
<PAGE>
 
         (iv) The Administrative Agent shall provide Borrower with written
     notice of whether the Required Lenders have approved a Property for

     information with respect to such Property required by SECTION 2.4(a)(i)
     (other than appraisals and environmental assessments), and (B) ten (10)
     Business Days after Borrower has provided to the Administrative Agent
     appraisals and environmental assessments with respect to such Property
     required by SECTION 2.4(a)(i).

         (v) An Eligible Project shall not be admitted into the Borrowing Base
     until (1) Borrower or an Obligor shall have executed and delivered to the
     Administrative Agent, for the ratable benefit of the Lenders, Collateral
     Documents covering such Project, (2) Borrower or such Obligor shall have
     delivered to the Administrative Agent appropriate and customary opinions of
     counsel, including an opinion of local counsel in substantially the form of
     EXHIBIT H, and (3) the Administrative Agent shall have a perfected first
     priority Lien in such Project, for the ratable benefit of the Lenders.

         (vi) The Administrative Agent may, on behalf of the Required Lenders in
     their sole discretion, notify Borrower that a Property that is not
     otherwise an Eligible Project may be included in the Borrowing Base,
     provided that the Required Lenders may require additional terms and
     conditions to be evidenced in writing as a supplement to this Agreement in
     order for such Property to be admitted into the Borrowing Base.

         (viii) Pursuant to SECTION 7.7, Borrower shall pay to the
     Administrative Agent all reasonable out-of-pocket expenses of the
     Administrative Agent incurred in connection with the Administrative Agent's
     review of requests for a Property to be admitted into the Borrowing Base.

     (b) BORROWING BASE.

         (i) The "INDIVIDUAL BORROWING BASE" for any Project admitted into the
     Borrowing Base shall be, as of any date: (A) for any Project acquired by
     Borrower or one of its Consolidated Affiliates prior to the IPO, the
     Approved Percentage of the Appraised Value of such Project (determined
     using the most recent appraisal delivered to or required by Agent); and (B)
     for any Project acquired by Borrower or one of its Consolidated Affiliates
     on or after the IPO, the lesser of: (1) the Approved Percentage of the
     Approved Costs of such Project; and (2) the Approved Percentage of the
     Appraised Value of such Project (determined using the most recent appraisal

     the sum of the Individual Borrowing Bases for each of the Projects admitted
     into the Borrowing Base; and (B) the Aggregate Borrowing Base.

      (c) OTHER REQUIREMENTS RESPECTING THE BORROWING BASE.  During the term

                                       14

notify Borrower and the Lenders in writing of any changes to the Borrowing Base
as a result of the admission of such Project into the Borrowing Base.

     (e)  PROJECTS ADMITTED INTO BORROWING BASE.  The Projects admitted into the
Borrowing Base are listed on SCHEDULE 2 (as supplemented from time-to-time to
reflect additional Projects admitted into the Borrowing Base, as herein
provided).

SECTION 3 TERMS OF PAYMENT.

     3.1  NOTES AND PAYMENTS.

     (a)  The Principal Debt shall be evidenced by the Notes, one payable to
each Lender in the stated principal amount of its Commitment.

     (b)  Borrower must make each payment and prepayment on the Obligation,
without offset, counterclaim, or deduction, to the Administrative Agent's
principal office in Dallas, Texas, in funds that will be available for immediate
use by the Administrative Agent by 12:00 noon on the day due.  Payments received
after such time shall be deemed received on the next Business Day.  The
Administrative Agent shall pay to each Lender any payment to which such Lender
is entitled on the same day the Administrative Agent receives the funds from
Borrower if the Administrative Agent receives the payment or prepayment before
12:00 noon, and otherwise before 12:00 noon on the following Business Day.  If
and to the extent that the Administrative Agent does not make payments to the
Lenders when due, then the Administrative Agent shall be obligated to pay to the
Lenders such unpaid amounts together with interest at the Federal Funds Rate
from the due date until (but not including) the payment date.

     3.2  INTEREST AND PRINCIPAL PAYMENTS.

     (a)  INTEREST PAYMENTS.  Accrued interest on each Borrowing is due and
payable on the first (1st) day of each calendar month during the term of this
Agreement, commencing on November 1, 1996, and on the Termination Date.

     (b)  PRINCIPAL PAYMENTS.  The Total Principal Debt is due and payable on
the Termination Date.

     (c)  VOLUNTARY PREPAYMENT.  Borrower may voluntarily repay or prepay all or
any part of the Total Principal Debt at any time without premium or penalty,
subject to the following conditions:

          (i) the Administrative Agent must receive Borrower's written payment
     notice by 11:00 a.m. on (A) the Business Day preceding the date of payment
     of a Eurodollar Borrowing, and (B) the Business Day preceding the date of
     payment of a Base Rate Borrowing, which shall specify the payment date and
     the Type and amount of the Borrowing(s) to be paid, and which shall
     constitute an irrevocable and binding obligation of Borrower to make a
     repayment or prepayment on the designated date;

          (ii) each partial repayment or prepayment must be in a minimum amount
     of at least $1,000,000.00 or a greater integral multiple of $100,000.00,
     or, if less, the Total Principal Debt; and

                                       15
<PAGE>
 
          (iii) Borrower shall pay any related Funding Loss upon demand.

     (d)  MANDATORY PREPAYMENT.  Notwithstanding anything contained herein or in
the Notes to the contrary, if at any time the outstanding Total Principal Debt
exceeds the Borrowing Base, then Borrower shall immediately prepay in
immediately available funds such excess balance, together with any related
Funding Loss.

     3.3  INTEREST OPTIONS.  Except as specifically otherwise provided,
Borrowings shall bear interest at an annual rate equal to the lesser of (a) the
Base Rate plus the Applicable Margin, or the Eurodollar Rate plus the Applicable
Margin (in each case as designated or deemed designated by Borrower and, in the
case of Eurodollar Borrowings, for the Interest Period designated by Borrower),
and (b) the Maximum Rate.  Each change in the Base Rate and Maximum Rate is
effective, without notice to Borrower or any other Person, upon the effective
date of change.

     3.4  QUOTATION OF RATES.  A Representative of Borrower may call the
Administrative Agent before delivering a Borrowing Request to receive an
indication of the interest rates then in effect, but the indicated rates do not
bind the Administrative Agent or the Lenders or affect the interest rate that is
actually in effect when Borrower delivers its Borrowing Request or on the
Borrowing Date.

     3.5  DEFAULT RATE.  If permitted by applicable law, all past-due Principal
Debt and past-due interest accruing on any of the foregoing, bears interest from
the date due (stated or by acceleration) at the Default Rate until paid,
regardless of whether payment is made before or after entry of a judgment.

     3.6  INTEREST RECAPTURE.  If the designated interest rate applicable to any
Borrowing exceeds the Maximum Rate, then the interest rate on that Borrowing is
limited to the Maximum Rate, provided that any subsequent reductions in the
designated rate shall not reduce the interest rate thereon below the Maximum
Rate until the total amount of accrued interest equals the amount of interest
that would have accrued if that designated rate had always been in effect.  If
at maturity (stated or by acceleration), or at final payment of the Notes, the
total interest paid or accrued is less than the interest that would have accrued
if the designated rates had always been in effect, then, at that time and to the
extent permitted by applicable law, Borrower shall pay an amount equal to the
difference between (a) the lesser of the amount of interest that would have
accrued if the designated rates had always been in effect and the amount of
interest that would have accrued if the Maximum Rate had always been in effect,
and (b) the amount of interest actually paid or accrued on the Notes.

     3.7  INTEREST CALCULATIONS.

     (a)  Interest shall be calculated on the basis of actual number of days
elapsed (including the first day but excluding the last day) but computed as if
each calendar year consisted of 360 days for all Borrowings (unless the
calculation would result in an interest rate greater than the Maximum Rate, in
which event interest shall be calculated on the basis of a year of 365 or 366
days, as the case may be). All interest rate determinations and calculations by
the Administrative Agent are conclusive and binding absent manifest error.

     (b)  The provisions of this Agreement relating to calculation of the Base
Rate and the Eurodollar Rate are included only for the purpose of determining
the rate of interest or other amounts to be paid under this Agreement that are
based upon those rates.  Each Lender may fund and maintain its funding of all or
any part of each Borrowing as it selects.

     3.8  MAXIMUM RATE.  Regardless of any provision contained in any Loan
Document or any document related thereto, it is the intent of the parties to
this Agreement that no Agent nor any Lender contract for, charge, take, reserve,
receive or apply, as interest on all or any part of the Obligation any amount in
excess of the Maximum Rate or the Maximum Amount or receive any unearned
interest in violation of any applicable 

                                       16
<PAGE>
 
law, and, if any Agent or any Lender ever does so, then any excess shall be
treated as a partial repayment or prepayment of principal and any remaining
excess shall be refunded to Borrower. In determining if the interest paid or
payable exceeds the Maximum Rate, Borrower, Agents and the Lenders shall, to the
maximum extent permitted under applicable law, (a) treat all Borrowings as but a
single extension of credit (and the Lenders and Borrower agree that is the case
and that provision in this Agreement for multiple Borrowings is for convenience
only), (b) characterize any nonprincipal payment as an expense, fee or premium
rather than as interest, (c) exclude voluntary repayments or prepayments and
their effects, and (d) amortize, prorate, allocate and spread the total amount
of interest throughout the entire contemplated term of the Obligation. If,
however, the Obligation is paid in full before the end of its full contemplated
term, and if the interest received for its actual period of existence exceeds
the Maximum Amount, then the Lenders shall refund any excess (and the Lenders
may not, to the extent permitted by applicable law, be subject to any penalties
provided by any Governmental Requirements for contracting for, charging, taking,
reserving or receiving interest in excess of the Maximum Amount). If the
Governmental Requirements of the State of Texas are applicable for purposes of
determining the "Maximum Rate" or the "Maximum Amount," then those terms mean
the "indicated rate ceiling" from time-to-time in effect under Article 5069-
1.04, Title 79, Revised Civil Statutes of Texas, as amended. Borrower agrees
that Chapter 15, Subtitle 79, Revised Civil Statutes of Texas, 1925, as amended
(which regulates certain revolving credit loan accounts and revolving tri-party
accounts), does not apply to the Obligation, other than Article 15.10(b).

     3.9  INTEREST PERIODS.  When Borrower requests any Eurodollar Borrowing,
Borrower may elect the applicable interest period (each an "INTEREST PERIOD"),
which may be, at Borrower's option, one (1), two (2), three (3) or six (6)
months, subject to the following conditions:  (a) the initial Interest Period
for a Eurodollar Borrowing commences on the applicable Borrowing Date or
conversion date, and each subsequent Interest Period applicable to any Borrowing
commences on the day when the next preceding applicable Interest Period expires;
(b) if any Interest Period for a Eurodollar Borrowing begins on a day for which
there exists no numerically corresponding Business Day in the calendar month at
the end of the Interest Period ("ENDING CALENDAR MONTH"), then the Interest
Period ends on the next succeeding Business Day of the Ending Calendar Month,
unless there is no succeeding Business Day in the Ending Calendar Month in which
case the Interest Period ends on the next preceding Business Day of the Ending
Calendar Month; (c) no Interest Period for any portion of Principal Debt may
extend beyond the scheduled repayment date for that portion of Principal Debt;
and (d) there may not be in effect at any one time more than five (5) Interest
Periods.

     3.10 CONVERSIONS.  Borrower may (a) on the last day of the applicable
Interest Period (or at any other time, subject to payment of any Funding Loss)
convert all or part of a Eurodollar Borrowing to a Base Rate Borrowing, (b) at
any time convert all or part of a Base Rate Borrowing to a Eurodollar Borrowing,
and (c) on the last day of an Interest Period, elect a new Interest Period for a
Eurodollar Borrowing.  Any such conversion is subject to the dollar limits and
denominations of SECTION 2.1 and may be accomplished by delivering a Conversion
Request to the Administrative Agent no later than 11:00 a.m. (i) on the third
(3rd) Business Day before (A) the conversion date for conversion to a Eurodollar
Borrowing, and (B) the last day of the Interest Period, for the election of a
new Interest Period, and (ii) one (1) Business Day before the last day of the
Interest Period for conversion to a Base Rate Borrowing. Absent Borrower's
notice of conversion or election of a new Interest Period, a Eurodollar
Borrowing shall be converted to a Base Rate Borrowing when the applicable
Interest Period expires.

     3.11 ORDER OF APPLICATION.

     (a)  NO DEFAULT.  If no Default exists, then except as otherwise
specifically provided in the Loan Documents,  any payment shall be applied to
the Obligation in the order and manner as Borrower directs.

     (b)  DEFAULT.  If a Default exists, any payment (including proceeds from
the exercise of any Rights) shall be applied in the following order: (i) to all
fees and expenses and Protective Advances for which 

                                       17
<PAGE>
 
any Agent or the Lenders have not been paid or reimbursed in accordance with the
Loan Documents (and if such payment is less than all unpaid or unreimbursed fees
and expenses, then the payment shall be paid against unpaid and unreimbursed
fees and expenses in the order of incurrence or due date); (ii) to accrued
interest on the Principal Debt; and (iii) to the remaining Obligation in the
order and manner as the Required Lenders deem appropriate.

     (c)  PRO RATA.  Each payment or prepayment shall be distributed to each
Lender in accordance with its Pro Rata Part of such payment or prepayment.

     3.12 SHARING OF PAYMENTS, ETC.  If any Lender obtains any amount (whether
voluntary, involuntary or otherwise, including as a result of exercising its
Rights under SECTION 3.13) that exceeds the part of that payment that such
Lender is then entitled to receive under the Loan Documents, then such Lender
shall purchase from the other Lenders participations that will cause the
purchasing Lender to share the excess amount ratably with each other Lender.  If
all or any portion of any excess amount is subsequently recovered from the
purchasing Lender, then the purchase shall be rescinded and the purchase price
restored to the extent of the recovery.  Borrower agrees that any Lender
purchasing a participation from another Lender under this section may, to the
fullest extent permitted by applicable law, exercise all of its Rights of
payment with respect to that participation as fully as if such Lender were the
direct creditor of Borrower in the amount of that participation.

     3.13 BOOKING BORROWINGS.  To the extent permitted by applicable law, any
Lender may make, carry or transfer its Borrowings at, to, or for the account of
any of its branch offices or the office of any of its Affiliates.  However, no
Affiliate is entitled to receive any greater payment under SECTION 3.15 than the
transferor Lender would have been entitled to receive with respect to those
Borrowings, and a transfer may not be made if, as a direct result of it, SECTION
3.15 or 3.16 would apply to any of the Obligation. If any of the conditions of
SECTIONS 3.15 or 3.16 ever apply to a Lender, then such Lender shall, to the
extent possible, carry or transfer its Borrowings at, to, or for the account of
any of its branch offices or the office or branch of any of its Affiliates so
long as the transfer is consistent with the other provisions of this section,
does not create any burden or adverse circumstance for such Lender that would
not otherwise exist, and eliminates or ameliorates the conditions of SECTIONS
3.15 or 3.16 as applicable.

     3.14 BASIS UNAVAILABLE OR INADEQUATE FOR THE EURODOLLAR RATE.  If (a)
the Administrative Agent determines that the basis for determining the
applicable rate is not available, or (b) any Lender determines that the
resulting rate does not accurately reflect the cost to such Lender of making or
converting Borrowings at that rate for the applicable Interest Period, then:

          (i)  in the case of (a), the Administrative Agent shall promptly
     notify Borrower and the Lenders of that determination (which is conclusive
     and binding on Borrower absent manifest error), and all Borrowings shall
     bear interest at the sum of the Base Rate plus the Applicable Margin. Until
     the Administrative Agent notifies Borrower that such circumstances no
     longer exist, the Lenders' commitments under this Agreement to make, or to
     convert to, Eurodollar Borrowings shall be suspended; and

          (ii) in the case of (b), such Lender shall promptly notify the
     Administrative Agent and Borrower, and all Borrowings of such Lender shall
     bear interest at the sum of the Base Rate plus the Applicable Margin. Until
     the Administrative Agent notifies Borrower that such circumstances no
     longer exist, such Lender's commitment under this Agreement to make, or to
     convert to, Eurodollar Borrowings shall be suspended.

     3.15 ADDITIONAL COSTS.

                                       18
<PAGE>
 
     (a)  RESERVES.  With respect to any Eurodollar Borrowing, if (i) any change
in present Governmental Requirement, any change in the interpretation or
application of any present Governmental Requirement, or any future Governmental
Requirement imposes, modifies, or deems applicable (or if compliance by any
Lender with any such requirement of any Governmental Authority results in) any
such requirement that any reserves (including any marginal, emergency,
supplemental or special reserves) be maintained, and (ii) those reserves reduce
any sums receivable by such Lender under this Agreement or increase the costs
incurred by such Lender in advancing or maintaining any portion of any
Eurodollar Borrowing, then (unless the effect is already reflected in the rate
of interest then applicable under this Agreement) such Lender (through the
Administrative Agent) shall deliver to Borrower a certificate setting forth in
reasonable detail the calculation of the amount necessary to compensate it for
its reduction or increase (which certificate is conclusive and binding absent
manifest error), and Borrower shall promptly pay that amount to such Lender upon
demand.

     (b)  CAPITAL ADEQUACY.  With respect to any Borrowing, if any change in
present Governmental Requirement or any future Governmental Requirement
regarding capital adequacy or compliance by the Administrative Agent or any
Lender with any request, directive or requirement now existing or hereafter
imposed by any Governmental Authority regarding capital adequacy, or any change
in its written policies or in the risk category of this transaction, reduces the
rate of return on its capital as a consequence of its obligations under this
Agreement to a level below that which it otherwise could have achieved (taking
into consideration its policies with respect to capital adequacy) by an amount
deemed by it to be material (and it may, in determining the amount, use
reasonable assumptions and allocations of costs and expenses and use any
reasonable averaging or attribution method), then (unless the effect is already
reflected in the rate of interest then applicable under this Agreement) the
Administrative Agent or such Lender (through the Administrative Agent) shall
notify Borrower and deliver to Borrower a certificate setting forth in
reasonable detail the calculation of the amount necessary to compensate it
(which certificate is conclusive and binding absent manifest error), and
Borrower shall promptly pay that amount to the Administrative Agent or such
Lender upon demand.

     (c)  TAXES.  Any Taxes payable by the Administrative Agent or any Lender or
ruled (by a Governmental Authority) payable by the Administrative Agent or any
Lender in respect of this Agreement or any other Loan Document shall, if
permitted by Governmental Requirement, be paid by Borrower, together with
interest and penalties, if any (except for Taxes imposed on or measured by the
overall net income of the Administrative Agent or such Lender). The
Administrative Agent or such Lender (through the Administrative Agent) shall
notify Borrower and deliver to Borrower a certificate setting forth in
reasonable detail the calculation of the amount of payable Taxes, which
certificate is conclusive and binding (absent manifest error), and Borrower
shall promptly pay that amount to the Administrative Agent for its account or
the account of such Lender, as the case may be. If the Administrative Agent or
such Lender subsequently receives a refund of the Taxes paid to it by Borrower,
then the recipient shall promptly pay the refund to Borrower.

     (d)  SURVIVAL.  The provisions of this SECTION 3.15 shall survive the
satisfaction and payment of the Obligation and termination of this Agreement.

     3.16 CHANGE IN GOVERNMENTAL REQUIREMENT.  If any Governmental Requirement
makes it unlawful for any Lender to make or maintain Eurodollar Borrowings, then
such Lender shall promptly notify Borrower and the Administrative Agent, and (a)
as to undisbursed funds, that requested Borrowing shall be made as a Base Rate
Borrowing, and (b), as to any outstanding Borrowing, (i) if maintaining the
Borrowing until the last day of the applicable Interest Period is unlawful, the
Borrowing shall be converted to a Base Rate Borrowing as of the date of notice,
and Borrower shall pay any related Funding Loss, or (ii) if not prohibited by
all Governmental Requirements, the Borrowing shall be converted to a Base Rate
Borrowing as of the last day of the applicable Interest Period, or (iii) if any
conversion will not resolve the unlawfulness, Borrower shall promptly prepay the
Borrowing, without penalty, together with any related Funding Loss.

                                       19
<PAGE>
 
     3.17 FUNDING LOSS.  BORROWER AGREES TO INDEMNIFY EACH LENDER AGAINST, AND
PAY TO IT UPON DEMAND, ANY FUNDING LOSS OF SUCH LENDER.  When any Lender demands
that Borrower pay any Funding Loss, such Lender shall deliver to Borrower and
the Administrative Agent a certificate setting forth in reasonable detail the
basis for imposing Funding Loss and the calculation of the amount, which
calculation is conclusive and binding absent manifest error.  The provisions of
this SECTION 3.17 shall survive the satisfaction and payment of the Obligation
and termination of this Agreement.

     3.18 FOREIGN LENDERS.  Each Lender that is organized under the
Governmental Requirements of any jurisdiction other than the United States of
America or any State thereof (a) represents to the Administrative Agent and
Borrower that (i) no Taxes are required to be withheld by the Administrative
Agent or Borrower with respect to any payments to be made to it in respect of
the Obligation, and (ii) it has furnished to the Administrative Agent and
Borrower two (2) duly completed copies of U.S. Internal Revenue Service Form
4224, Form 1001, Form W-8, or any other tax form acceptable to the
Administrative Agent (wherein it claims entitlement to complete exemption from
U.S. federal withholding tax on all interest payments under the Loan Documents),
and (b) covenants to (i) provide the Administrative Agent and Borrower a new tax
form upon the expiration or obsolescence of any previously delivered form
according to Governmental Requirement, duly executed and completed by it, and
(ii) comply from time-to-time with all Governmental Requirements with regard to
the withholding tax exemption.  If any of the foregoing is not true or the
applicable forms are not provided, then Borrower or the Administrative Agent
(without duplication) may deduct and withhold from interest payments under the
Loan Documents United States federal income tax at the full rate applicable
under the Code.

     3.19 FEES.

     (a)  TREATMENT OF FEES.  The fees described in this SECTION 3.19 (i) are
not compensation for the use, detention, or forbearance of money, (ii) are in
addition to, and not in lieu of, interest and expenses otherwise described in
this Agreement, (iii) are payable in accordance with SECTION 3.1(b), (iv) are
non-refundable, (v) to the fullest extent permitted by applicable law, bear
interest, if not paid when due, at the Default Rate, and (vi) are calculated on
the basis of actual number of days (including the first day but excluding the
last day) elapsed, but computed as if each calendar year consisted of 360 days,
unless computation would result in an interest rate in excess of the Maximum
Rate in which event the computation is made on the basis of a year of 365 or 366
days, as the case may be. The fees described in this SECTION 3.19 are in all
events subject to the provisions of SECTION 3.8.

     (b)  AGENT FEES.  Borrower shall pay to each Agent, solely for their own
accounts, the fees described in the letter agreement(s) between Borrower and the
Agents dated the same date as this Agreement, as such letter agreement(s) may be
modified or amended from time-to-time.

     (c)  COMMITMENT FEES.

          (i) Borrower shall pay to the Administrative Agent, for the account of
     the Lenders, the commitment fees described in the letter agreement between
     Borrower, the Administrative Agent and the Lenders dated the same date as
     this Agreement.

          (ii) Borrower agrees to pay to the Administrative Agent, for the
     ratable account of the Lenders, a commitment fee equal to the sum of the
     amounts obtained by multiplying the average daily Unused Commitment set
     forth below times the applicable percentage set forth opposite such portion
     below:

========================================================================== 
UNUSED COMMITMENTS                         APPLICABLE PERCENTAGE PER ANNUM

Equal to or greater than $50,000,000.00                     0.25 %
==========================================================================
</TABLE>

Such commitment fee shall be due and payable in arrears on the first (1st) day
of each April, July, October, and January during the term hereof, commencing on
January 1, 1997, and on the Termination Date, based upon the Unused Commitment
for each day during the quarter ending on such date.  Solely for purposes of
this SECTION 3.19(c), "ratable" means, for any calculation period, with respect
to any Lender, the proportion that (A) the average daily unused Commitment of
such Lender during the period bears to (B) the aggregate amount of the average
daily unused Total Commitment during the period.

SECTION 4 SECURITY.

     4.1  LIENS ON PROJECTS.  As more fully described in the Collateral
Documents, Borrower shall, and shall cause each Obligor to, grant to the
Administrative Agent, for the benefit of the Lenders, as security for the
payment and performance of the Obligation, a valid, enforceable, perfected,
first priority and (except for Permitted Liens) only Lien in and to each
Project, or, if a Project is leased, then Borrower's or each Obligor's rights
and leasehold interests in and to such Project.

     4.2  COLLATERAL DOCUMENTS.  The Liens described in SECTION 4.1 shall be
granted pursuant to, and more fully described in, the Collateral Documents.

     4.3  LEASES.

     (a)  Unless the Administrative Agent shall give Borrower written notice
pursuant to (b) below, Borrower may (without the prior consent of the
Administrative Agent) execute leases covering all or any portion of a Project
after the date of this Agreement so long as such leases (i) are on forms that
are customary and consistent with institutional grade warehouse or office
properties or are in substantially the form of an Approved Lease Form, and (ii)
have provisions that provide for the same basic terms as Sections G-5, G-6, O, 
Q-3, and Q-16 in the form of the Approved Lease Form for industrial properties
and Sections 10.02, 12.01, 18, and 25.05 in the form of Approved Lease Form for
office properties. Borrower may (without the prior consent of the Administrative
Agent) enter into renewal, extension, or expansion agreements (which agreements
shall be customary and consistent with institutional grade warehouse or office
properties or Borrower's past leasing practices) with tenants under leases
existing as of the date of admission of such Project into the Borrowing Base
covering all or any portion of a Project; provided, however, that if the
Administrative Agent shall determine, after a semi-annual review of leasing
activities by Borrower, that Borrower has engaged in significant leasing
activities with respect to any Project wherein the same basic terms as Sections
G-5, G-6, O, Q-3, and Q-16 in the Approved Lease Form for industrial properties
and Sections 10.02, 12.01, 18, and 25.05 in the form of Approved Lease Form for
office properties have not been included, which in the sole discretion of the
Administrative Agent results in a material adverse affect on the value of the
Project as Collateral hereunder, then the Administrative Agent may, in its sole
discretion, notify Borrower on or before October 1 or April 1 of each year
during the term of the Loan that its has elected to remove such Project from the
Borrowing Base (a "REMOVAL NOTICE"). If the Administrative Agent shall have
delivered a Removal Notice to Borrower, then Borrower may, on or before the
immediately following January 1 or July 1, either (a) submit additional
Properties to the Administrative Agent for admission into the Borrowing Base by
the Required Lenders in accordance with SECTION 2.4, or (b) if necessary, prepay
the excess of the Total Principal Debt over the Borrowing Base. Notwithstanding
the foregoing, Borrower may (without the prior consent of the Administrative
Agent) execute agreements covering a Project pursuant to renewal, extension, or
expansion options set forth in leases existing as of the date of admission into
the Borrowing Base, provided that the non-economic terms and conditions of such
renewal agreements do not materially differ from the terms and

                                       21
<PAGE>
 
conditions of the leases renewed or extended thereby.

     (b)  If the Administrative Agent shall have given Borrower written notice
(which notice may be delivered by the Administrative Agent only if a Default
exists), then unless otherwise consented to by the Administrative Agent in
writing, all leases covering all or any portion of a Project entered into after
the date of such notice and while a Default exists (i) shall be in substantially
the form of an Approved Lease Form, (ii) shall have no material changes to
Sections G-5, G-6, O, Q-3, and Q-16 in the Approved Lease Form for industrial
properties and Sections 10.02, 12.01, 18, and 25.05  in the form of Approved
Lease Form for office properties, and (iii) may include other provisions
specifically approved in writing by the Administrative Agent or in other lease
guidelines agreed to by the Administrative Agent in writing from time-to-time.

     (c)  Unless otherwise consented to by the Administrative Agent in writing,
all leases covering all or any portion of a Project entered into after the date
of this Agreement shall (i) be to third parties under market terms (ii) provide
for uses of the premises that are consistent with institutional grade warehouse
or office properties (which shall include, without limitation, other current
uses in the applicable Project), (iii) not provide for uses of the premises that
would materially and adversely affect the fair market value of the Project or
the Project's ability to qualify for permanent financing, and (iv) not provide
for the Administrative Agent's or any subsequent mortgagee's non-disturbance of
any tenant's occupancy, unless agreed to by the Administrative Agent pursuant to
a subordination, attornment, and non-disturbance agreement in form and substance
reasonably acceptable to the Administrative Agent or otherwise in writing.

     (d)  Borrower shall send to the Administrative Agent copies of all leases
(and all renewals, extension, or modifications thereof) covering all or any
portion of a Project entered into after the date of this Agreement within thirty
(30) days after the last day of each fiscal quarter immediately following the
execution thereof.

     (e)  The Administrative Agent shall not be obligated to execute a
subordination, attornment, and non-disturbance agreement with any tenant in a
Project, but agrees to exercise its reasonable best efforts to respond within
ten (10) days to any request from Borrower for the Administrative Agent to
execute a subordination, attornment, and non-disturbance agreement with a tenant
in a Project; provided that the failure to so respond shall be deemed to be a
denial of such request.

     4.4  RELEASES OF COLLATERAL.  The Administrative Agent shall have no
obligation to release any Collateral without a written request from Borrower,
together with a Borrowing Base Report certified by a Responsible Officer of
Borrower, setting forth in reasonable detail the calculations required to
establish the amount of the Borrowing Base without such Project, and a
Compliance Certificate as of the date of such request.  The Administrative Agent
shall not release any Collateral unless, after giving effect to any such release
(a) no Default or Potential Default exists, (b) the Borrowing Base exceeds the
Obligation as of the date of such release, and (c) unless waived by the Required
Lenders, at least five (5) Projects remain in the Borrowing Base.  The
Administrative Agent shall not be required to partially release a portion of a
Project pursuant to this SECTION.

     4.5  APPRAISALS.  The Administrative Agent may at its option obtain, at
Borrower's expense, but not more often than once each calendar year during the
term of this Agreement, an appraisal of each Project or any part thereof
prepared in accordance with written instructions from the Administrative Agent
by a third-party appraiser engaged directly by the Administrative Agent.  Each
such appraiser and appraisal shall be satisfactory to the Administrative Agent;
provided that if the Administrative Agent has previously engaged an appraiser
with respect to a Project, then the Administrative Agent shall, to the extent
reasonably practicable under the circumstances, use the same appraiser for
subsequent appraisals of the same Project.

                                       22
<PAGE>
 
     4.6  GUARANTY.  Pursuant to the Guaranty, Guarantor shall unconditionally
guarantee in favor of the Agents and the Lenders the full payment and
performance of the Obligation.

SECTION 5 CONDITIONS PRECEDENT.

     (a)  The Lenders will not be obligated to fund the initial Borrowing
hereunder unless the Administrative Agent has timely received: (i) a Borrowing
Request;  (ii) all of the items described on the attached SCHEDULE 5; and (iii)
evidence that the IPO shall have occurred.

     (b)  In addition, the Lenders will not be obligated to make any Borrowing,
unless on the applicable Borrowing Date (and after giving effect to the
requested Borrowing): (i) the Administrative Agent shall have timely received a
Borrowing Request; (ii) the Administrative Agent shall have received all
applicable fees; (iii) all of the representations and warranties in the Loan
Documents are true and correct in all material respects (unless they speak to a
specific date or are based on facts which have changed by transactions expressly
contemplated or permitted by this Agreement); (iv) no Default, Potential
Default, or Material Adverse Event exists; and (v) the funding of the Borrowing
is permitted by all Governmental Requirements.  Upon the Administrative Agent's
request, Borrower shall deliver to the Administrative Agent evidence
substantiating any of the matters in the Loan Documents that are necessary to
enable Borrower to qualify for the Borrowing.  Each condition precedent in this
Agreement (including those on the attached SCHEDULE 5) is material to the
transactions contemplated by this Agreement, and time is of the essence with
respect to each condition precedent.  The Lenders may fund any Borrowing without
all conditions being satisfied, but, to the extent permitted by Governmental
Requirement, that funding and issuance shall not be deemed to be a waiver of the
requirement that each condition precedent be satisfied as a prerequisite for any
subsequent funding or issuance, unless the Required Lenders specifically waive
each item in writing.

SECTION 6 REPRESENTATIONS AND WARRANTIES.  Borrower represents and warrants
to the Agents and the Lenders as follows:

     6.1  PURPOSE OF CREDIT FACILITY.  Borrower shall use proceeds of the
Borrowings hereunder to acquire, subject to SECTION 8.6, office and industrial
Properties, raw land, properties under construction, partnership interests,
interests in other Persons, investments in mortgages and loans, and other
acquisitions or investments permitted hereunder, and for working capital
purposes of Borrower and its Consolidated Affiliates.  Borrower is not engaged
principally, or as one of its important activities, in the business of extending
credit for the purpose of purchasing or carrying any "margin stock" within the
meaning of Regulation U of the Board of Governors of the Federal Reserve System,
as amended.  No part of the proceeds of any Borrowing shall be used, directly or
indirectly, for a purpose that violates any Governmental Requirement, including
the provisions of Regulation U.

     6.2  EXISTENCE, GOOD STANDING, AUTHORITY AND COMPLIANCE.  Each Company is
duly formed, validly existing and in good standing under the Governmental

Each Company (a) is duly qualified to transact business and is in good standing
as a foreign trust, corporation, partnership, or other entity in each
jurisdiction where the nature and extent of its business and properties require
due qualification and good standing, which jurisdictions are identified on the

result of transactions permitted by the Loan Documents), except where the
failure to so qualify could not result in a Material Adverse Event, (b)
possesses all requisite authority, permits and power to conduct its business as
is now being, or is contemplated by this Agreement to be, conducted, and (c) is
in compliance with all applicable Governmental Requirements.

                                       23

Governmental Requirement or order of any Governmental Authority applicable to
it, (f) do not violate any material agreements to which it is a party, or (g) do
not result in the creation or imposition of any Lien on any asset of any
Company, other than pursuant to the Loan Documents.

     6.5  BINDING EFFECT.  Upon execution and delivery by all parties thereto,
each Loan Document to which it is a party shall constitute a legal and binding
obligation of each Company, enforceable against such Company in accordance with
its terms, subject to applicable Debtor Relief Laws and general principles of
equity.

     6.6  FINANCIAL STATEMENTS; FISCAL YEAR.  The Current Financials were
prepared in accordance with GAAP and present fairly, in all material respects,
the consolidated financial condition, results of operations, and cash flows of
the Companies as of, and for the portion of the fiscal year ending on the date
or dates thereof (subject only to normal audit adjustments).  All material
liabilities of the Companies as of the date or dates of the Current Financials
are reflected therein or in the notes thereto.  Except for transactions directly
related to, or specifically contemplated by, the Loan Documents or disclosed in
the Current Financials, no subsequent material adverse changes have occurred in
the consolidated financial condition of the Companies from that shown in the
Current Financials. The fiscal year of each Company ends on December 31.

     6.7  LITIGATION.  Except as disclosed on the attached SCHEDULE 6.7, no
Company is subject to, or aware of the threat of, any Litigation that is
reasonably likely to be determined adversely to such Company or the Companies,

outstanding and unpaid final and non-appealable judgments against any Company
exist which could result in a Material Adverse Event.

     6.8  TAXES.

     (a)  All Tax returns of each Company required to be filed have been filed
(or extensions have been granted) before delinquency, and all Taxes imposed upon
each Company that are due and payable have been paid before delinquency or are
being contested in good faith by appropriate proceedings diligently conducted
and for which reserves in accordance with GAAP or otherwise reasonably
acceptable to the Administrative Agent have been provided.

     (b)  As of the date hereof, no United States federal income tax returns of
the "affiliated group" (as defined in the Code) of which any Company is a member
have been examined and closed.  The members of such affiliated group have filed
all United States Federal income tax returns and all other material tax returns
which are required to be filed by them and have paid all taxes due pursuant to
such returns or pursuant to any assessment received by or any of them (except
for taxes being contested in good faith by appropriate proceedings diligently
conducted and for which reserves in accordance with GAAP or otherwise acceptable

                                       24
<PAGE>
 
to the Administrative Agent have been provided).  The charges, accruals and
reserves on the books of the Companies in respect of taxes or other governmental
charges are, in the opinion of the Companies, adequate.

     (c)  Guarantor qualifies as a REIT.

     6.9 ENVIRONMENTAL MATTERS.  Except as disclosed on SCHEDULE 6.9 and as
specifically disclosed to the Administrative Agent in a written environmental
report or other writing delivered by Borrower to the Administrative Agent prior

materials, used and stored in commercially reasonable quantities and in
compliance with applicable Environmental Laws, and (ii) light manufacturing and
distribution activities of tenants, in compliance with applicable Environmental
Laws, provided that such tenants are not primarily engaged in the treatment,
processing, recycling or disposal of any Hazardous Substance, or for any other
use that would give rise to the release of any Hazardous Substance on such
facility.  Each Company has taken prudent steps to determine that its properties
and operations do not violate any Environmental Law.

     6.10 EMPLOYEE PLANS.  Except where occurrence or existence could not
reasonably be expected to result in a Material Adverse Event, (a) no Employee
Plan has incurred an "accumulated funding deficiency" (as defined in Section 302
of ERISA or Section 412 of the Code), (b) no Company has incurred liability

to the date of determination), to be less than 2.25 to 1.0.  For purposes of the
foregoing, EBITDA and Interest Expense shall include Borrower's or Guarantor's

SECTION 11 RIGHTS AND REMEDIES.

     11.1  REMEDIES UPON DEFAULT.

     (a)   DEBTOR RELIEF.  If a Default (i) occurs under SECTION 10.3(c) or (ii)
occurs and is continuing under SECTION 10.3(a), (b) OR (d), the commitment to
extend credit under this Agreement automatically terminates, the entire unpaid
balance of the Obligation automatically becomes due and payable without any
action of any kind whatsoever.

     (b)   OTHER DEFAULTS.  If a Default occurs and is continuing, subject to
the terms of SECTION 13.9(b), then the Administrative Agent, upon the request of
the Required Lenders, may do any one or more of the following: (i) if the
maturity of the Obligation has not already been accelerated under SECTION
11.1(a), declare the entire unpaid balance of all or any part of the Obligation
immediately due and payable, whereupon it is due and payable; (ii) terminate the
commitments of the Lenders to extend credit under this Agreement; (iii) reduce
any claim to judgment; and (iv) exercise any and all other legal or equitable
Rights afforded by the Loan Documents, the Governmental Requirements of the
State of Texas, or any other applicable jurisdiction.

     11.2  WAIVERS.  To the extent permitted by applicable law, each Company
waives presentment and demand for payment, protest, notice of intention to
accelerate, notice of acceleration, and notice of protest and nonpayment, and
agrees that its liability with respect to all or any part of the Obligation is
not affected by any renewal or extension in the time of payment of all or any
part of the Obligation, by any indulgence, or by any release or change in any
security for the payment of all or any part of the Obligation.

     11.3  PERFORMANCE BY THE ADMINISTRATIVE AGENT.  If any covenant, duty, or
agreement of Borrower is not performed in accordance with the terms of the Loan
Documents, the Administrative Agent may, while a Default exists, at its option,
perform, or attempt to perform that covenant, duty, or agreement on behalf of
Borrower (and any amount expended by the Administrative Agent in its performance
or attempted performance is payable by Borrower to the Administrative Agent on
demand, becomes part of the Obligation, and bears interest at the Default Rate
from the date of the Administrative Agent's expenditure until paid).  However,
neither the Administrative Agent nor any Lender assumes or shall have, except by
its express written consent, any liability or responsibility for the performance
of any covenant, duty, or agreement of Borrower.

     11.4  NOT IN CONTROL.  None of the covenants or other provisions contained
in any Loan Document shall, or shall be deemed to, give the Agents or the
Lenders the Right to exercise control over the assets (including real property),
affairs, or management of any Company.

                                       35
<PAGE>
 
     11.5  COURSE OF DEALING.  The acceptance by the Agents or any Lender of
any partial payment on the Obligation shall not be deemed to be a waiver of any
Default then existing.  No waiver by any Agent or any Lender of any Default
shall be deemed to be a waiver of any other then-existing or subsequent Default.
No delay or omission by any Agent or any Lender in exercising any Right under
the Loan Documents will impair that Right or be construed as a waiver thereof or
any acquiescence therein, nor will any single or partial exercise of any Right
preclude other or further exercise thereof or the exercise of any other Right
under the Loan Documents or otherwise.

     11.6  CUMULATIVE RIGHTS.  All Rights available to the Agents and the
Lenders under the Loan Documents are cumulative of and in addition to all other
Rights granted to the Agents and the Lenders at law or in equity, whether or not
the Obligation is due and payable and whether or not the Agents or the Lenders
have instituted any suit for collection, foreclosure, or other action in
connection with the Loan Documents.

     11.7  APPLICATION OF PROCEEDS.  Any and all proceeds ever received by any
Agent or any Lender from the exercise of any Rights pertaining to the Obligation
shall be applied to the Obligation according to SECTION 3.11.

     11.8  DIMINUTION IN VALUE OF COLLATERAL.  No Agent nor any Lender has any
liability or responsibility whatsoever for any diminution in or loss of value of
any Collateral now or hereafter securing payment or performance of all or any
part of the Obligation (other than diminution in or loss of value caused by its
gross negligence or willful misconduct).

     11.9  CERTAIN PROCEEDINGS.  Borrower shall promptly execute and deliver,
or cause the execution and delivery of, all applications, certificates,
instruments, and all other documents and papers any Agent reasonably requests in
connection with the obtaining of any consent, approval, registration,
qualification, permit, license, or authorization of any Governmental Authority
or other Person necessary or appropriate for the effective exercise of any
Rights under the Loan Documents.  Because Borrower agrees that the Agents' and
the Lenders' remedies at law for failure of Borrower to comply with the
provisions of this paragraph would be inadequate and that failure would not be
adequately compensable in damages, Borrower agrees that the covenants of this
paragraph may be specifically enforced.

SECTION 12 AGENTS AND THE LENDERS.

     12.1  THE AGENTS.

     (a) APPOINTMENT.  Each Lender appoints the Administrative Agent (including,
without limitation, each successor Agent in accordance with this SECTION 12) as
its nominee and agent to act in its name and on its behalf (and the
Administrative Agent and each such successor accepts that appointment):  (i) to
act as its nominee and on its behalf in and under all Loan Documents; (ii) to
arrange the means whereby its funds are to be made available to Borrower under
the Loan Documents; (iii) to take any action that it properly requests under the
Loan Documents (subject to the concurrence of other Lenders as may be required
under the Loan Documents); (iv) to receive all documents and items to be
furnished to it under the Loan Documents; (v) to be the secured party,
mortgagee, beneficiary, recipient, and similar party in respect of any
Collateral, for the benefit of Lenders; (vi) to promptly distribute to it all
Financial Statements, Borrowing Base Reports, notices received hereunder, and
other items specifically required to be delivered to it hereunder, and, upon
request, such other material information, requests, documents, and items
received under the Loan Documents; (vii) to promptly distribute to it its
ratable part of each payment or prepayment (whether voluntary, as proceeds of
collateral upon or after foreclosure, as proceeds of insurance thereon, or
otherwise) in accordance with the terms of the Loan Documents; and (viii) to
deliver to the appropriate Persons requests, demands, approvals, and consents
received from it.  However, the Administrative Agent may not be required to take
any action that 

                                       36
<PAGE>
 
exposes it to personal liability or that is contrary to any Loan Document or
applicable Governmental Requirement.

     (b)   SUCCESSOR.  The Administrative Agent may assign all of its Rights and
obligations as Administrative Agent under the Loan Documents to any of its
Affiliates, which Affiliate shall then be the successor Administrative Agent
under the Loan Documents.  The Administrative Agent may also voluntarily resign
by notice to Borrower and Lenders, and shall resign upon the request of the
Required Lenders for cause (i.e., the Administrative Agent is continuing to fail
to perform its responsibilities as the Administrative Agent under the Loan
Documents). If the initial or any successor Administrative Agent ever ceases to
be a party to this Agreement or if the initial or any successor Administrative
Agent ever resigns (whether voluntarily or at the request of the Required
Lenders), then the Required Lenders shall (which, if no Default or Potential
Default exists, is subject to Borrower's approval that may not be unreasonably
withheld) appoint the successor Administrative Agent from among the Lenders
(other than the resigning Administrative Agent). If the Required Lenders fail to
appoint a successor Administrative Agent within thirty (30) days after the
resigning Administrative Agent has given notice of resignation or the Required
Lenders have removed the resigning Administrative Agent, then the resigning
Administrative Agent may, on behalf of the Lenders, appoint a successor
Administrative Agent (which, if no Default or Potential Default exists, is
subject to Borrower's approval that may not be unreasonably withheld), which
must be a commercial bank having a combined capital and surplus of at least
$1,000,000,000.00 (as shown on its most recently published statement of
condition) and whose debt obligations (or whose parent's debt obligations) are
rated not less than Baa1 by Moody's or BBB+ by S & P. Upon its acceptance of
appointment as successor Administrative Agent, the successor Administrative
Agent succeeds to and becomes vested with all of the Rights of the prior
Administrative Agent, and the prior Administrative Agent is discharged from its
duties and obligations of the Administrative Agent under the Loan Documents, and
each Lender shall execute the documents that any Lender, the resigning or
removed Administrative Agent, or the successor Administrative Agent reasonably
request to reflect the change. After any Administrative Agent's resignation or
removal as Administrative Agent under the Loan Documents, the provisions of this
SECTION inure to its benefit as to any actions taken or not taken by it while it
was the Administrative Agent under the Loan Documents.

     (c)   RIGHTS AS LENDER.  Each Agent, in its capacity as a Lender, has the
same Rights under the Loan Documents as any other Lender and may exercise those
Rights as if it were not acting as an Agent.  The term "Lender," unless the
context otherwise indicates, includes the Agents.  The Administrative Agent's
resignation or removal does not impair or otherwise affect any Rights that it
has or may have in its capacity as an individual Lender.  Each Lender and
Borrower agree that the Agents are not a fiduciary for Lenders or for Borrower
but are simply acting in the capacities described in this Agreement to alleviate
administrative burdens for Borrower and Lenders, that the Agents have no duties
or responsibilities to Lenders or Borrower except those expressly set forth in
the Loan Documents, and that each Agent in its capacity as a Lender has the same
Rights as any other Lender.

     (d)   OTHER ACTIVITIES.  Any Agent or any Lender may now or in the future
be engaged in one or more loan, letter of credit, leasing, or other financing
transactions with Borrower or another Company, act as trustee or depositary for
Borrower or another Company, or otherwise be engaged in other transactions with
Borrower (collectively, the "OTHER ACTIVITIES") not the subject of the Loan
Documents. Without limiting the Rights of Lenders specifically set forth in the
Loan Documents, no Agent nor any Lender is responsible to account to the other
Lenders for those other activities, and no Lender shall have any interest in any
other Lender's activities, any present or future guaranties by or for the
account of Borrower that are not contemplated by or included in the Loan
Documents, any present or future offset exercised by any Agent or any Lender in
respect of those other activities, any present or future property taken as
security for any of those other activities, or any property now or hereafter in
any Agent's or any other Lender's possession or control that may be or become
security for the obligations of Borrower arising under the Loan Documents by
reason of the general description of indebtedness secured or of property
contained in any other agreements,

                                       37
<PAGE>
 
documents, or instruments related to any of those other activities (but, if any
payments in respect of those guaranties or that property or the proceeds thereof
is applied by any Agent or any Lender to reduce the Obligation, then each Lender
is entitled to share ratably in the application as provided in the Loan
Documents).

     (e)   THE DOCUMENTATION AGENT.  The Documentation Agent shall have no
rights, duties, or obligations hereunder, except as specifically provided in
this Agreement. The Documentation Agent (a) may voluntarily resign by notice to
the Administrative Agent, the Lenders, and Borrower, and (b) shall resign upon
the request of the Required Lenders for cause. Upon the resignation of the
Documentation Agent, the Required Lenders may elect to designate a successor
Documentation Agent (which, if no Default or Potential Default exists, is
subject to Borrower's approval that may not be unreasonably withheld), which
must be a Lender who is a commercial bank having a combined capital and surplus
of at least $1,000,000,000.00 (as shown on its most recently published statement
of condition) and whose debt obligations (or whose parent's debt obligations)
are rated not less than Baa1 by Moody's or BBB+ by S & P.

     12.2  EXPENSES.  Should the Administrative Agent commence any proceeding
or in any way seek to enforce its Rights under the Loan Documents, irrespective
of whether as a result thereof the Administrative Agent shall acquire title to
any Collateral, either through foreclosure, deed in lieu of foreclosure, or
otherwise, each Lender, upon demand therefor from time-to-time, shall contribute
its share (based on its Pro Rata Part) of the reasonable costs and/or expenses
of any such enforcement or acquisition, including, but not limited to, fees of
receivers or trustees, court costs, title company charges, filing and recording
fees, appraisers' fees and fees and expenses of attorneys to the extent not
otherwise reimbursed by Borrower.  Without limiting the generality of the
foregoing, each Lender shall contribute its share (based on its Pro Rata Part)
of all reasonable costs and expenses incurred by the Administrative Agent
(including reasonable attorneys' fees and expenses) if the Administrative Agent
employs counsel for advice or other representation (whether or not any suit has
been or shall be filed) with respect to any Collateral or any part thereof, or
any of the Loan Documents, or the attempt to enforce any Lien in any of the
Collateral, or to enforce any rights of the Administrative Agent or any of
Borrower's or any other Company's obligations under any of the Loan Documents,
but not with respect to any dispute between the Administrative Agent and any
other Lender(s).  Any loss of principal and interest resulting from any Default
shall be shared by Lenders in accordance with their respective Pro Rata Parts.
It is understood and agreed that the Administrative Agent determines that it is
necessary to engage counsel for the Lenders from and after the occurrence of a
Potential Default or Default , said counsel shall be selected by the
Administrative Agent and written notice of the same shall be delivered to the
Lenders.

     12.3  PROPORTIONATE ABSORPTION OF LOSSES.  Except as otherwise provided in
the Loan Documents, nothing in the Loan Documents gives any Lender any advantage
over any other Lender insofar as the Obligation is concerned or relieves any
Lender from ratably absorbing any losses sustained with respect to the
Obligation (except to the extent unilateral actions or inactions by any Lender
result in Borrower or any other obligor on the Obligation having any credit,
allowance, setoff, defense, or counterclaim solely with respect to all or any
part of that Lender's Pro Rata Part of the Obligation).

     12.4  DELEGATION OF DUTIES; RELIANCE.  Lenders may perform any of their
duties or exercise any of their Rights under the Loan Documents by or through
the Administrative Agent, and Lenders and the Administrative Agent may perform
any of their duties or exercise any of their Rights under the Loan Documents by
or through their respective Representatives.  The Administrative Agent, Lenders,
and their respective Representatives (a) are entitled to rely upon (and shall be
protected in relying upon) any written or oral statement believed by it or them
to be genuine and correct and to have been signed or made by the proper Person
and, with respect to legal matters, upon opinion of counsel selected by the
Administrative Agent or that Lender (but nothing in this CLAUSE (a) permits the
Administrative Agent to rely on (i) oral statements if a writing is required by
this Agreement or (ii) any other writing if a specific writing is required by
this Agreement), (b) are entitled to deem and treat each Lender as the owner and
holder of its portion of the 

                                       38
<PAGE>
 
Obligation for all purposes until, written notice of the assignment or transfer
is given to and received by the Administrative Agent (and any request,
authorization, consent, or approval of any Lender is conclusive and binding on
each subsequent holder, assignee, or transferee of or Participant in that
Lender's portion of the Obligation until that notice is given and received), (c)
are not deemed to have notice of the occurrence of a Default unless a
Responsible Officer of the Administrative Agent, who handles matters associated
with the Loan Documents and transactions thereunder, has actual knowledge or the
Administrative Agent has been notified by a Lender or Borrower, and (d) are
entitled to consult with legal counsel (including counsel for Borrower),
independent accountants, and other experts selected by the Administrative Agent
and are not liable for any action taken or not taken in good faith by it in
accordance with the advice of counsel, accountants, or experts.

     12.5  LIMITATION OF AGENTS' LIABILITY.

     (a)   EXCULPATION.  No Agent nor any of their Affiliates or Representatives
will be liable for any action taken or omitted to be taken by it or them under
the Loan Documents in good faith and believed by it or them to be within the
discretion or power conferred upon it or them by the Loan Documents or be
responsible for the consequences of any error of judgment (except for fraud,
gross negligence, or willful misconduct), and no Agent nor any of its Affiliates
or Representatives has a fiduciary relationship with any Lender by virtue of the
Loan Documents (but nothing in this Agreement negates the obligation of the
Administrative Agent to account for funds received by it for the account of any
Lender).

     (b)   INDEMNITY. Unless indemnified to its satisfaction against loss, cost,
liability, and expense, no Agent may be compelled to do any act under the Loan
Documents or to take any action toward the execution or enforcement of the
powers thereby created or to prosecute or defend any suit in respect of the Loan
Documents. If an Agent requests instructions from the Lenders, or the Required
Lenders, as the case may be, with respect to any act or action in connection
with any Loan Document, such Agent is entitled to refrain (without incurring any
liability to any Person by so refraining) from that act or action unless and
until it has received instructions.  In no event, however, may any Agent or any
of its Representatives be required to take any action that it or they determine
could incur for it or them criminal or onerous civil liability.  Without
limiting the generality of the foregoing, no Lender has any right of action
against any Agent as a result of such Agent's acting or refraining from acting
under this Agreement in accordance with instructions of the Required Lenders.

     (c)   RELIANCE.  No Agent is not responsible to any Lender or any
Participant for, and each Lender represents and warrants that it has not relied
upon any Agent in respect of, (i) the creditworthiness of Borrower or Guarantor
and the risks involved to that Lender, (ii) the effectiveness, enforceability,
genuineness, validity, or the due execution of any Loan Document (except by such
Agent), (iii) any representation, warranty, document, certificate, report, or
statement made therein (except by such Agent) or furnished thereunder or in
connection therewith, (iv) the adequacy of any Collateral now or hereafter
securing the Obligation or the existence, priority, or perfection of any Lien
now or hereafter granted or purported to be granted on the Collateral under any
Loan Document, or (v) observation of or compliance with any of the terms,
covenants, or conditions of any Loan Document on the part of any Company. EACH
LENDER AGREES TO INDEMNIFY EACH AGENT AND ITS REPRESENTATIVES AND HOLD THEM
HARMLESS FROM AND AGAINST (BUT LIMITED TO SUCH LENDER'S COMMITMENT PRO RATA PART
OF) ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS,
JUDGMENTS, SUITS, COSTS, REASONABLE EXPENSES, AND REASONABLE DISBURSEMENTS OF
ANY KIND OR NATURE WHATSOEVER THAT MAY BE IMPOSED ON, ASSERTED AGAINST, OR
INCURRED BY THEM IN ANY WAY RELATING TO OR ARISING OUT OF THE LOAN DOCUMENTS OR
ANY ACTION TAKEN OR OMITTED BY THEM UNDER THE LOAN DOCUMENTS IF SUCH AGENT AND
ITS REPRESENTATIVES ARE NOT REIMBURSED FOR SUCH AMOUNTS BY ANY COMPANY. ALTHOUGH
EACH AGENT AND ITS REPRESENTATIVES HAVE THE RIGHT TO BE INDEMNIFIED UNDER THIS
AGREEMENT FOR ITS OR THEIR OWN ORDINARY NEGLIGENCE, EACH AGENT AND ITS
REPRESENTATIVES DO NOT HAVE THE RIGHT 

                                       39
<PAGE>
 
TO BE INDEMNIFIED UNDER THIS AGREEMENT FOR ITS OR THEIR OWN FRAUD, GROSS
NEGLIGENCE, OR WILLFUL MISCONDUCT.

     12.6  DEFAULT.  While a Default exists, the Lenders agree to promptly
confer in order that the Required Lenders or the Lenders, as the case may be,
may agree upon a course of action for the enforcement of the Rights of the
Lenders.  The Administrative Agent is entitled to act or refrain from taking any
action (without incurring any liability to any Person for so acting or
refraining) unless and until it has received instructions from Required Lenders.
In actions with respect to any Company's property, the Administrative Agent is
acting for the ratable benefit of each Lender.

     12.7  COLLATERAL MATTERS.

     (a)   Each Lender authorizes and directs the Administrative Agent to enter
into the Loan Documents and agrees that any action taken by the Administrative
Agent concerning any Collateral (with the consent or at the request of the
Required Lenders) in accordance with any Loan Document, that the Administrative
Agent's exercise (with the consent or at the request of the Required Lenders) of
powers concerning the Collateral in any Loan Document, and that all other
reasonably incidental powers are authorized and binding upon all Lenders.

     (b)   The Administrative Agent is authorized on behalf of all Lenders,
without the necessity of any notice to or further consent from any Lender, from
time-to-time before a Default or Potential Default, to take any action with
respect to any Collateral or Loan Documents related to Collateral that may be
necessary to perfect and maintain the Administrative Agent's Liens in the
Collateral including, without limitation, making Protective Advances; provided,
however, the Administrative Agent shall not, without the consent of the Required
Lenders, make any Protective Advances during any one (1) calendar year in excess
of the sum of (i) amounts expended to pay real estate taxes, assessments, and
governmental charges or levies imposed upon the Collateral, (ii) amounts
expended to pay insurance premiums for policies of insurance related to the
Collateral, and (iii) $250,000.00.

     (c)   Except to use the same standard of care that it ordinarily uses for
collateral for its sole benefit, the Administrative Agent has no obligation
whatsoever to any Lender or to any other Person to assure that the Collateral
exists or is owned by any Company or is cared for, protected, or insured or has
been encumbered or that the Administrative Agent's Liens have been properly or
sufficiently or lawfully created, perfected, protected, or enforced or are
entitled to any particular priority.

     (d)   The Administrative Agent shall exercise the same care and prudent
judgment with respect to the Collateral and the Loan Documents as it normally
and customarily exercises in respect of similar collateral and security
documents.

     (e)   Lenders irrevocably authorize the Administrative Agent, at its option
and in its discretion, to release any Liens upon any Collateral (i) in
accordance with SECTION 4.4, (ii) constituting property being disposed of as
permitted under any Loan Document, or (iii) if approved, authorized, or ratified
in writing by the Required Lenders.  Upon request by the Administrative Agent at
any time, Lenders shall confirm in writing the Administrative Agent's authority
to release particular types or items of Collateral under this CLAUSE (e).

     (f)   In the event that all or any portion of the Collateral is acquired by
the Administrative Agent as the result of a foreclosure or the acceptance of a
deed or assignment in lieu of foreclosure, or is retained in satisfaction of all
or any part of the Obligation, title to any such Collateral or any portion
thereof shall be held in the name of the Administrative Agent or a nominee or
subsidiary of the Administrative Agent (which in any case is authorized to do
business in the state in which such Collateral is located), as agent, for the
ratable 

                                       40
<PAGE>
 
benefit of the Administrative Agent and the Lenders.  The Administrative
Agent shall prepare a recommended course of action for such Collateral (the
"POST-FORECLOSURE PLAN"), which shall be subject to the approval of the Required
Lenders, or shall take such action as directed by the Required Lenders. The
Administrative Agent shall manage, operate, repair, administer, complete,
construct, restore or otherwise deal with the Collateral acquired and administer
all transactions relating thereto, including, without limitation, employing a
management agent and other agents, contractors and employees, including agents
of the sale of such Collateral, and the collecting of rents and other sums from
such Collateral and paying the expenses of such Collateral. Upon demand therefor
from time to time, each Lender will contribute its share (based on its Pro Rata
Part) of all reasonable costs and expenses incurred by the Administrative Agent
pursuant to the Post-Foreclosure Plan in connection with the construction,
operation, management, maintenance, leasing and sale of such Collateral. In
addition, the Administrative Agent shall render or cause to be rendered by the
managing agent, to each of the Lenders, monthly, an income and expense statement
for such Collateral, and each of the Lenders shall promptly contribute its Pro
Rata Part of any operating loss for such Collateral, and such other expenses and
operating reserves as the Administrative Agent shall deem reasonably necessary
pursuant to and in accordance with the Post-Foreclosure Plan. To the extent
there is net operating income from such Collateral, the Administrative Agent
shall, in accordance with the Post-Foreclosure Plan, determine the amount and
timing of distributions to the Lenders. All such distributions shall be made to
the Lenders in accordance with their respective Pro Rata Parts. The Lenders
acknowledge that if title to any Collateral is obtained by the Administrative
Agent or its nominee, such Collateral will not be held as a permanent investment
but will be liquidated as soon as practicable. The Administrative Agent shall
undertake to sell such Collateral, at such price and upon such terms and
conditions as the Required Lenders shall reasonably determine to be most
advantageous. Any purchase money mortgage or deed of trust taken in connection
with the disposition of such Collateral in accordance with the immediately
preceding sentence shall name the Administrative Agent, as agent for the
Lenders, as the beneficiary or mortgagee. In such case, the Administrative Agent
and the Lenders shall enter into an agreement with respect to such purchase
money mortgage defining the rights of the Lenders in the same Pro Rata Parts as
provided hereunder, which agreement shall be in all material respects similar to
this Agreement insofar as this Agreement is appropriate or applicable.

     12.8  LIMITATION OF LIABILITY.  No Lender or any Participant will incur
any liability to any other Lender or Participant except for acts or omissions in
bad faith, and neither the Administrative Agent nor any Lender or Participant
will incur any liability to any other Person for any act or omission of any
other Lender or any Participant.

     12.9  RELATIONSHIP OF LENDERS.  The Loan Documents do not create a
partnership or joint venture among Agents and the Lenders or among the Lenders.

     12.10 BENEFITS OF AGREEMENT.  None of the provisions of this SECTION
inure to the benefit of any Company or any other Person except the Agents and
the Lenders.  Therefore, no Company nor any other Person is responsible or
liable for, entitled to rely upon, or entitled to raise as a defense -- in any
manner whatsoever -- the failure of any Agent or any Lender to comply with these
provisions.

     12.11 APPROVAL OF LENDERS.

     (a)   All communications from the Administrative Agent to the Lenders
requesting the Lenders' determination, consent, approval, or disapproval (i)
shall be given in the form of a written notice to each Lender, (ii) shall be
accompanied by a description of the matter or thing as to which such
determination, approval, consent, or disapproval is requested, or shall advise
each Lender where such matter or thing may be inspected, or shall otherwise
describe the matter or issue to be resolved, (iii) shall include, if reasonably
requested by a Lender and to the extent not previously provided to such Lender,
written materials and a summary of all oral information provided to the
Administrative Agent by Borrower in respect of the matter 

                                       41
<PAGE>
 
or issue to be resolved, and (iv) shall include the Administrative Agent's
recommended course of action or determination in respect thereof. Each Lender
shall reply promptly, but in any event (x) within thirty (30) days (or such
lesser period as may be required under the Loan Documents for the Administrative
Agent to respond) for those matters requiring the consent by all Lenders, and
(y) within fifteen (15) Business Days (or such lesser period as may be required
under the Loan Documents for the Administrative Agent to respond) for those
matters requiring the consent by the Required Lenders, in each instance, after
receipt of the request therefore by the Administrative Agent (in either event,
the "LENDER REPLY PERIOD").

     (b)   Unless a Lender shall give written notice to the Administrative Agent
that it objects to the recommendation or determination of the Administrative
Agent (together with a written explanation of the reasons behind such objection)
within the Lender Reply Period, such Lender shall be deemed to have approved of
or consented to such recommendation or determination.

SECTION 13 MISCELLANEOUS.

     13.1  HEADINGS.  The headings, captions and arrangements used in any of
the Loan Documents are, unless specified otherwise, for convenience only and
shall not be deemed to limit, amplify or modify the terms of the Loan Documents,
nor affect the meaning thereof.

     13.2  NONBUSINESS DAYS; TIME.  Any payment or action that is due under any
Loan Document on a non-Business Day may be delayed until the next-succeeding
Business Day (but interest shall continue to accrue on any applicable payment
until payment is in fact made) unless the payment concerns a Eurodollar
Borrowing, in which case if the next-succeeding Business Day is in the next
calendar month, then such payment shall be made on the next-preceding Business
Day.

     13.3  COMMUNICATIONS.  Unless otherwise specifically provided, whenever
any Loan Document requires or permits any consent, approval, notice, request,
demand or other communication from one party to another, communication must be
in writing (which may be by telex or telecopy) to be effective and shall be
deemed to have been given (a) if by telex, when transmitted to the appropriate
telex number and the appropriate answerback is received, (b) if by telecopy,
when transmitted to the appropriate telecopy number (and all communications sent
by telecopy must be confirmed promptly thereafter by telephone; but any
requirement in this parenthetical shall not affect the date when the telecopy
shall be deemed to have been delivered), (c) if by mail, on the fifth (5th)
Business Day after it is enclosed in an envelope and properly addressed,
stamped, sealed, certified mail, return receipt requested, and deposited in the
appropriate official postal service, or (d) if by any other means, when actually
delivered.  Until changed by notice pursuant to this Agreement, the address (and
telecopy number) for each party to a Loan Document is set forth on the attached
SCHEDULE 1.

     13.4  FORM AND NUMBER OF DOCUMENTS.  The form, substance, and number of
counterparts of each writing to be furnished under this Agreement must be
satisfactory to the Agents and their counsel.

     13.5  SURVIVAL.  All covenants, agreements, undertakings, representations
and warranties made in any of the Loan Documents survive all closings under the
Loan Documents and, except as otherwise indicated, are not affected by any
investigation made by any party.

     13.6  GOVERNING LAW.  Except as expressly provided in a Loan Document, the
Governmental Requirements (other than conflict-of-laws provisions) of the State
of Texas and of the United States of America govern the Rights and duties of the
parties to the Loan Documents and the validity, construction, enforcement and
interpretation of the Loan Documents.

                                       42
<PAGE>
 
     13.7  INVALID PROVISIONS.  Any provision in any Loan Document held to be
illegal, invalid or unenforceable is fully severable; the appropriate Loan
Document shall be construed and enforced as if that provision had never been
included; and the remaining provisions shall remain in full force and effect and
shall not be affected by the severed provision. The Agents, the Lenders, and
Borrower agree to negotiate, in good faith, the terms of a replacement provision
as similar to the severed provision as may be possible and be legal, valid and
enforceable. However, if the provision held to be illegal, invalid or
unenforceable is a material part of this Agreement, such invalid, illegal or
unenforceable provision shall be, to the extent permitted by applicable law,
replaced by a clause or provision judicially construed and interpreted to be as
similar in substance and content to the original terms of such illegal, invalid
or unenforceable clause or provision as the context thereof would reasonably
allow, so that such clause or provision would thereafter be legal, valid and
enforceable.

     13.8  VENUE; SERVICE OF PROCESS; JURY TRIAL.  EACH PARTY TO ANY LOAN
DOCUMENT, IN EACH CASE FOR ITSELF, ITS SUCCESSORS AND ASSIGNS (AND IN THE CASE
OF BORROWER, FOR EACH OF ITS CONSOLIDATED AFFILIATES), (a) IRREVOCABLY SUBMITS
TO THE NONEXCLUSIVE JURISDICTION OF THE STATE AND FEDERAL COURTS OF THE STATE OF
TEXAS, (b) IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY
OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY
LITIGATION ARISING OUT OF OR IN CONNECTION WITH THE LOAN DOCUMENTS AND THE
OBLIGATION BROUGHT IN DISTRICT COURTS OF DALLAS COUNTY, TEXAS, OR IN THE UNITED
STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF TEXAS, DALLAS DIVISION, (c)
IRREVOCABLY WAIVES ANY CLAIMS THAT ANY LITIGATION BROUGHT IN ANY OF THE
AFOREMENTIONED COURTS HAS BEEN BROUGHT IN AN INCONVENIENT FORUM, (d) IRREVOCABLY
CONSENTS TO THE SERVICE OF PROCESS OUT OF ANY OF THOSE COURTS IN ANY LITIGATION
BY THE MAILING OF COPIES THEREOF BY CERTIFIED MAIL, RETURN RECEIPT REQUESTED,
POSTAGE PREPAID, BY HAND-DELIVERY, OR BY DELIVERY BY A NATIONALLY RECOGNIZED
COURIER SERVICE, AND SERVICE SHALL BE DEEMED COMPLETE UPON DELIVERY OF THE LEGAL
PROCESS AT ITS ADDRESS SET FORTH IN THIS AGREEMENT, (e) IRREVOCABLY AGREES THAT
ANY LEGAL PROCEEDING AGAINST ANY PARTY TO ANY LOAN DOCUMENT ARISING OUT OF OR IN
CONNECTION WITH THE LOAN DOCUMENTS OR THE OBLIGATION MAY BE BROUGHT IN ONE OF
THE AFOREMENTIONED COURTS, AND (f) IRREVOCABLY WAIVES TO THE FULLEST EXTENT
PERMITTED BY LAW, ITS RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF
ACTION BASED UPON OR ARISING OUT OF ANY LOAN DOCUMENT.  The scope of each of the
foregoing waivers is intended to be all-encompassing of any and all disputes
that may be filed in any court and that relate to the subject matter of this
transaction, including contract claims, tort claims, breach of duty claims, and
all other common law and statutory claims.  Borrower (for itself and on behalf
of each of its Consolidated Affiliates) acknowledges that these waivers are a
material inducement to the Administrative Agent's and each Lender's agreement to
enter into a business relationship, that the Administrative Agent and each
Lender has already relied on these waivers in entering into this Agreement, and
that the Administrative Agent and each Lender will continue to rely on each of
these waivers in related future dealings.  Borrower (for itself and on behalf of
each of its Consolidated Affiliates) further warrants and represents that it has
reviewed these waivers with its legal counsel, and that it knowingly and
voluntarily agrees to each waiver following consultation with legal counsel.
THE WAIVERS IN THIS SECTION 13.8 ARE IRREVOCABLE, MEANING THAT THEY MAY NOT BE
MODIFIED EITHER ORALLY OR IN WRITING, AND THESE WAIVERS SHALL APPLY TO ANY
SUBSEQUENT AMENDMENTS, SUPPLEMENTS, OR REPLACEMENTS TO OR OF THIS OR ANY OTHER
LOAN DOCUMENT.  In the event of Litigation, this Agreement may be filed as a
written consent to a trial by the court.

                                       43

     13.9  AMENDMENTS, CONSENTS, CONFLICTS AND WAIVERS.

     (a)   REQUIRED LENDERS.  Unless otherwise specifically provided (i) the
provisions of this Agreement may be amended, modified, or waived, only by an
instrument in writing executed by Borrower and the Required Lenders and
supplemented only by documents delivered or to be delivered in accordance with
the express terms of this Agreement, and (ii) the Collateral Documents may only
be the subject of an amendment, modification, or waiver that has been approved
by the Administrative Agent and Borrower.

     (b)   ALL LENDERS.  Except as specifically otherwise provided in this
SECTION 13.9, any amendment to or consent or waiver under this Agreement or any
Loan Document that purports to accomplish any of the following must be by an
instrument in writing executed by Borrower and executed (or approved, as the
case may be) by each Lender: (i) extends the due date or decreases the amount of
any scheduled payment or amortization of the Obligation beyond the date
specified in the Loan Documents; (ii) decreases any rate or amount of interest,
fees, or other sums payable to Agents or Lenders under this Agreement (except
such reductions as are contemplated by this Agreement); (iii) changes the
definition of "COMMITMENT," "REQUIRED LENDERS," "PRO RATA PART," or the
percentages in the definition of "BORROWING BASE" and the defined terms used in
determining the Borrowing Base; (iv) increases any one or more Lenders'
Commitment; (v) waives compliance with, amends, or fully or partially releases
any Guaranty; or (vi) changes this CLAUSE (b) or any other matter specifically
requiring the consent of all Lenders under this Agreement.

     (c)   AGENTS.  No amendment, modification, consent or waiver which modifies
the rights, duties, or obligations of any Agent shall be effective without the
consent of such Agent.

     (d)   CONFLICTS.  Any conflict or ambiguity between the terms and
provisions of this Agreement and terms and provisions in any other Loan Document
is controlled by the terms and provisions of this Agreement.

     (e)   COURSE OF DEALING.  No course of dealing or any failure or delay by
any Agent, any Lender, or any of their respective Representatives with respect
to exercising any Right of any Agent or any Lender under this Agreement operates
as a waiver thereof. A waiver must be in writing and signed by the Required
Lenders or the Lenders, as appropriate, to be effective, and a waiver will be
effective only in the specific instance and for the specific purpose for which
it is given.

     13.10 MULTIPLE COUNTERPARTS.  Any Loan Document may be executed in a
number of identical counterparts, each of which shall be deemed an original for
all purposes and all of which constitute, collectively, one agreement; but, in
making proof of thereof, it shall not be necessary to produce or account for
more than one counterpart.  Each Lender need not execute the same counterpart of
this Agreement so long as identical counterparts are executed by Borrower, each
Lender, and each Agent.  This Agreement shall become effective when counterparts
of this Agreement have been executed and delivered to the Administrative Agent
by each Lender, each Agent, and Borrower, or, in the case only of the Lenders,
when the Administrative Agent has received telecopied, telexed or other evidence
satisfactory to it that each Lender has executed and is delivering to the
Administrative Agent a counterpart of this Agreement.

     13.11 SUCCESSORS AND ASSIGNS; PARTICIPATIONS.

     (a)   Each Loan Document binds and inures to the benefit of the parties
thereto, any intended beneficiary thereof, and each of their respective
successors and permitted assigns.  No Lender may transfer, pledge, assign, sell
any participation in, or otherwise encumber its portion of the Obligation,
except as permitted by this SECTION 13.11.

                                       44
<PAGE>
 
     (b)   Subject to the provisions of this section and in accordance with
applicable law, any Lender may, in the ordinary course of its commercial banking
business, at any time sell to one or more Eligible Assignees (each a
"PARTICIPANT") participating interests in its portion of the Obligation;
provided that each such participation is not less than $10,000,000.00.  The
selling Lender shall remain a "Lender" under this Agreement (and the Participant
shall not constitute a "Lender" under this Agreement) and its obligations under
this Agreement shall remain unchanged.  The selling Lender shall remain solely
responsible for the performance of its obligations under the Loan Documents and
shall remain the holder of its share of the Principal Debt for all purposes
under this Agreement.  Borrower and the Administrative Agent shall continue to
deal solely and directly with the selling Lender in connection with such
Lender's Rights and obligations under the Loan Documents.  Participants have no
Rights under the Loan Documents, other than certain voting Rights as provided
below.  Subject to the following, each Lender may obtain (on behalf of its
Participants) the benefits of SECTION 3 with respect to all participations in
its part of the Obligation outstanding from time-to-time so long as Borrower is
not obligated to pay any amount in excess of the amount that would be due to
such Lender under SECTION 3 calculated as though no participations have been
made.  No Lender may sell any participating interest under which the Participant
has any Rights to approve any amendment, modification or waiver of any Loan
Document, except to the extent the amendment, modification or waiver extends the
due date for payment of any principal, interest or fees due under the Loan
Documents, reduces the interest rate or the amount of principal or fees
applicable to the Obligation (except reductions contemplated by this Agreement),
or releases any guaranty or collateral, if any, for the Obligation.  However, if
a Participant is entitled to the benefits of SECTION 3 or a Lender grants Rights
to its Participants to approve amendments to or waivers of the Loan Documents
respecting the matters described in the previous sentence, then such Lender must
include a voting mechanism in the relevant participation agreement whereby a
majority of its portion of the Obligation (whether held by it or participated)
shall control the vote for all of such Lender's portion of the Obligation.
Except in the case of the sale of a participating interest to another Lender,
the relevant participation agreement shall prohibit the Participant from
transferring, pledging, assigning, selling participations in, or otherwise
encumbering its portion of the Obligation.

     (c)   Subject to the provisions of this section, any Lender having a
Commitment equal to or greater than $15,000,000.00, or if the Total Commitments
have been terminated, then Notes having outstanding Principal Debt equal to or
greater than $15,000,000.00, may at any time, in the ordinary course of its
commercial banking business, (i) without the consent of Borrower or the Agents,
assign all or any part of its Rights and obligations under the Loan Documents to
any of its Affiliates (each a "PURCHASER"), and (ii) upon the prior written
consent of the Agents, and so long as no Default or Potential Default exists,
Borrower, such consents not to be unreasonably withheld, assign to any Eligible
Assignee (each of which is also a "PURCHASER") a proportionate part (not less
than $15,000,000.00 and an integral multiple of $1,000,000.00) of all or any
part of its Rights and obligations under the Loan Documents; provided that
unless the Lender granting such assignment is assigning all of its Commitments
and Notes hereunder, after giving effect to such assignment, the Lender granting
such assignment shall retain a Commitment of at least $15,000,000.00, or if the
Total Commitments have been terminated, then Notes having outstanding Principal
Debt of at least $15,000,000.00.  Notwithstanding the foregoing, each Agent
shall, at all times prior to its resignation or replacement as an Agent
hereunder, retain a minimum Commitment of $25,000,000.00, or if the Total
Commitments have been terminated, then Notes having outstanding Principal Debt
of at least $25,000,000.00.  In each case, the Purchaser shall assume those
Rights and obligations under an assignment agreement substantially in the form
of the attached EXHIBIT E. Upon (i) delivery of an executed copy of the
assignment agreement to Borrower and the Administrative Agent and (ii) payment
of a fee of $3,000.00 from the transferor to the Administrative Agent, from and
after the assignment's effective date (which shall be after the date of
delivery), the Purchaser shall for all purposes be a Lender party to this
Agreement and shall have all the Rights and obligations of a Lender under this
Agreement to the same extent as if it were an original party to this Agreement
with commitments as set forth in the assignment agreement, and the transferor
Lender shall be released from its obligations under this Agreement to a
corresponding extent, and, except as provided in the following sentence, no
further consent or action by Borrower, the Lenders or the Administrative Agent

                                       45
<PAGE>
 
shall be required. Upon the consummation of any transfer to a Purchaser under
this CLAUSE (c), the then-existing SCHEDULE 1 shall automatically be deemed to
reflect the name, address, and Commitment of such Purchaser, the Administrative
Agent shall deliver to Borrower and the Lenders an amended SCHEDULE 1 reflecting
those changes, Borrower shall execute and deliver to each of the transferor
Lender and the Purchaser a Note in the face amount of its respective Commitment
following transfer, and, upon receipt of its new Note, the transferor Lender
shall return to Borrower the Note previously delivered to it under this
Agreement. A Purchaser is subject to all the provisions in this SECTION as if it
were a Lender signatory to this Agreement as of the date of this Agreement.

     (d)   Any Lender may at any time, without the consent of Borrower or the
Administrative Agent, assign all or any part of its Rights under the Loan
Documents to a Federal Reserve Bank without releasing the transferor Lender from
its obligations thereunder.

     (e)   Until the date which is three (3) months following the Closing Date
each Agent shall identify and solicit prospective Purchasers or Participants to
be assignees of or participants in the Rights and obligations of each Agent
under this Agreement (in such capacity, "SYNDICATING LENDERS") in an amount of
up to $50,000,000.00.  During such three (3) month period, the Syndicating
Lenders shall (i) not solicit or enter into any such assignment or participation
except as provided in this SECTION 13.11(e), and (ii) refer each prospective
Purchaser or Participant that expresses an interest in purchasing or acquiring
any such assignment or participation to the other Syndicating Lender.  Each
Syndicating Lender, upon identifying any prospective Purchaser or Participant
desiring to be an assignee of or participant in any portion of the Rights and
obligations of the Syndicating Lenders under this Agreement, shall deliver
written notice to the other Syndicating Lender of the terms of such transaction
("PROPOSED SYNDICATION TRANSACTION").  Each Syndicating Lender shall have the
right to participate in such Proposed Syndication Transaction on the terms set
forth in such notice by so notifying the other Syndicating Lender within five
(5) days of receiving such notice.  The assignment or participation effected by
such Proposed Syndication Transaction shall be allotted equally to each
participating Syndicating Lender.  Notwithstanding anything contained to the
contrary in SECTION 13.11(c), the aggregate assignments to a Purchaser by the
Syndicating Lenders shall be in an aggregate amount of not less $15,000,000.00
or a greater integral multiple of $1,000,000.00.

     (f)   No Lender may assign or participate all or any portion of its Rights
or obligations under this Agreement to any Company or any Affiliate of any
Company.

     (g)   Borrower acknowledges that the Syndicating Lenders may use their
Affiliates (other than a real estate development or management company) (and in
the case of the Documentation Agent, may use NationsBanc Capital Markets, Inc.)
to assist in the syndication of their Rights and obligations under this
Agreement.  Borrower acknowledges and consents that the Syndicating Lenders may
share information relating to Borrower, Guarantor, and the other Companies or
the transactions contemplated hereby with their respective Affiliates (other
than a real estate development or management company), and that such Affiliates
may likewise share information relating to Borrower, Guarantor, and the other
Companies or such transactions with the Syndicating Lenders.

     13.12 DISCHARGE ONLY UPON PAYMENT IN FULL; REINSTATEMENT IN CERTAIN
CIRCUMSTANCES. Borrower's obligations under the Loan Documents remain in full
force and effect until the Total Commitment is terminated and the Obligation is
paid in full (except for provisions under the Loan Documents which by their
terms expressly survive payment of the Obligation and termination of the Loan
Documents).  If at any time any payment of the principal of or interest on any
Note or any other amount payable by Borrower or any other obligor on the
Obligation under any Loan Document is rescinded or must be restored or returned
upon the insolvency, bankruptcy or reorganization of Borrower or otherwise, the
obligations of Borrower under the Loan Documents with respect to that payment
shall be reinstated as though the payment had been due but not made at that
time.

     13.13 ENTIRETY.  THIS AGREEMENT AND THE OTHER WRITTEN LOAN DOCUMENTS
(EACH AS AMENDED IN WRITING FROM TIME-TO-TIME) EXECUTED BY BORROWER, ANY LENDER
OR ANY AGENT REPRESENT THE FINAL AGREEMENT AMONG BORROWER, THE LENDERS AND
AGENTS AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR
SUBSEQUENT ORAL AGREEMENTS BY THE PARTIES.  THERE ARE NO UNWRITTEN ORAL
AGREEMENTS AMONG THE PARTIES.

     13.14 EFFECTIVENESS.  This Agreement is executed on October 17, 1996,
but shall not be effective until executed by all parties hereto and delivered to
and accepted by the Administrative Agent, and the other conditions set forth in
SECTION 5 have been satisfied or waived by the Lenders in writing.

                             ENVIRONMENTAL MATTERS


  The land (the "PLANT SITE") underlying one industrial complex containing
eighteen Industrial Properties, Pacific Gateway Center ("PGC"), was formerly the
site of a synthetic rubber manufacturing plant (the "PLANT") owned by the United
States Government and subsequently owned or operated by numerous companies,
including Shell Oil Company ("SHELL") and Dow Chemical Company ("DOW").  During
the operation of the Plant, wastes were disposed of in pits and ponds located
just to the south of PGC (the "PLANT SITE AFFECTED AREA").  In 1994, the Plant
Site Affected Area was deeded back to Shell by the Prentiss Group affiliate that
owned the property, and Shell agreed to indemnify the Prentiss Group affiliate
and any successors in interest against (i) any costs of remediation of the Plant
Site Affected Area and (ii) any suit for damages for personal injury or property
damage brought by neighboring landowners.

  Environmental studies conducted by Dow and Shell on the Plant Site have
detected the presence of groundwater contamination about 60 feet below the
surface of the Plant Site, which appears to be related to the operations of the
Plant.  Limited soil contamination has also been found on parcels in the area,
including parcels that will be owned by the Company.  In July 1991, the United
States Environmental Protection Agency ("EPA") proposed that the Plant Site be
listed on the National Priorities List ("NPL") of Superfund sites.  Comments
were submitted to the EPA challenging the proposal, and no action was taken by
the EPA.  On June 17, 1996, the EPA re-proposed that the Plant Site Affected
Area be listed on the NPL.  At this time, the Company cannot predict whether the
EPA will promulgate the proposed listing of the Plant Site Affected Area.  In
addition, PGC is located about one block east of an existing Superfund site, the
Montrose Chemical Superfund Site.  Contaminants associated with this site have
been detected in the groundwater in the vicinity of PGC.  Contamination also has
been found in groundwater to the south of the Plant Site Affected Area (the
"STUDY AREA").  According to reports prepared by or on behalf of Shell and Dow,
this contamination appears to be associated with leaks from pipelines located in
that area.

  All past and present owners of the land underlying PGC, including the United
States Government, Dow, Shell and the current owner, in which a Prentiss Group
affiliate is a general partner, are Potentially Responsible Parties for the
investigation and remediation of the Plant Site.  However, the current owner is
close in execution of an indemnification agreement with Shell whereby, in
consideration of the waiver by the current owner of any claim it might have
against Shell for damage to or diminution in the value of its property, Shell
would (i) agree to indemnify and hold harmless any successor of the current
owner, including the Company and any subsequent purchasers, tenants and lenders,
from any liability relating to clean up or remediation costs for the Plant Site
or for any contamination resulting from the interrelationship of (a) the
Montrose Chemical Superfund Site and/or the Study Area and (b) the Plant Site,
and (ii) indemnify and hold harmless any successor of the current owner,
including the Company, from any liability arising out of any third party tort
claims for personal injury or property damage.  While this indemnity does not
extend to claims for diminution in value or consequential damages resulting from
the remediation of the property or Shell's actions, any affected party,
including the Company, would have the right to make a claim for any such damages
against the responsible party.

  In addition to these indemnification arrangements, the EPA has indicated its
willingness to enter into a de minimis landowner settlement with the current
owner of PGC by which the owner would receive a release, covenant not to sue and
contribution protection from the United States in exchange for a one-time
payment.  The current owner has requested that the EPA extend that protection to
subsequent purchasers of all or any portion of the 

Page 7
<PAGE>
 
property; if successful, the benefit of this agreement would extend to the
Company.

  The Company believes that its effective share of any costs to remediate the
Plant Site will not have a material adverse effect on the Company.  The Company
believes that despite its possible technical liability as an owner or operator
of contaminated property, existing evidence makes clear that the contamination
of concern to the regulatory agencies did not result from the present use of the
Plant Site as an industrial park.  Further, the Company believes that the
existing and pending indemnifications from Shell and the potential future de
minimis settlement agreement with the EPA will protect the Company against any
future costs of a material nature.

  The ESAs for the Industrial Properties located in Milwaukee, Wisconsin,
revealed lead contamination in some of the soil near the property lines of two
of the Properties and the Development Parcel adjacent to those Properties (the
"MILWAUKEE AFFECTED AREAS").  The ESAs and the Wisconsin Department of Natural
Resources ("WDNR") have concluded that the contamination is the result of
unauthorized placement of contaminated soil by the owner of a vacant lot that is
located between the two Properties and the Development Parcel.  The placement
occurred prior to the acquisition of these Industrial Properties by the Prentiss
Group affiliate that currently owns the Properties.  The contaminated soil
consists of foundry sand which was found to contain lead in excess of acceptable
trace levels.  According to the ESA, the contamination does not affect the
groundwater and is not likely to migrate or leech into adjoining land or
groundwater in the future.  Upon discovery of the unauthorized placement, the
Company brought suit against the owner of the vacant lot, the generators of the
contaminated soil and the prior owner of the Properties.  A settlement to the
lawsuit has been entered into under which (i) the Company has transferred the
Milwaukee Affected Areas (a total of approximately 1.6 acres) to the owner of
the vacant lot in exchange for $100,000 and (ii) the owner of the vacant lot and
the generators of the contaminated soil agreed to assume all responsibility for
the remediation of the contaminated soil.  The court has entered a finding that
the Company was not in the chain of ownership of the Milwaukee Affected Areas.
Based on all available information, the Company does not believe that it will
incur any liability with respect to this contamination.

                               FORM OF GUARANTY


                       UNCONDITIONAL GUARANTY AGREEMENT

     THIS GUARANTY AGREEMENT is executed as of October 17, 1996, by PRENTISS
PROPERTIES TRUST, a Maryland real estate investment trust ("GUARANTOR") for the
benefit of the Loan Parties defined below.

                             W I T N E S S E T H:
                             - - - - - - - - - - 

     WHEREAS, Prentiss Properties Acquisition Partners, L.P., a Delaware limited
partnership ("BORROWER"), may from time-to-time be indebted to the Loan Parties
pursuant to that certain Credit Agreement dated of even date herewith (herein
referred to, together with all amendments, modifications, or supplements
thereof, as the "CREDIT AGREEMENT"), by and between Borrower, each of the
Lenders that are parties thereto (the "LENDERS"), Bank One, Texas, N.A., a
national banking association (the "ADMINISTRATIVE AGENT"), as Administrative
Agent for the Lenders, and NationsBank of Texas, N.A., a national banking
association (the "DOCUMENTATION AGENT"), as Documentation Agent for the Lenders
(the Lenders, the Administrative Agent, and the Documentation Agent, together
with their respective successors and assigns are herein called the "LOAN
PARTIES");

     WHEREAS, capitalized terms used herein shall, unless otherwise indicated,
have the respective meanings set forth in the Credit Agreement;

     WHEREAS, the Loan Parties are not willing to make loans under the Credit
Agreement or otherwise extend credit to Borrower unless Guarantor
unconditionally guarantees payment of all present and future indebtedness and
obligations of Borrower to the Loan Parties under the Credit Agreement and the
Loan Documents; and

     WHEREAS, Guarantor will benefit from the Loan Parties' extension of credit
to Borrower;

     NOW, THEREFORE, as an inducement to the Loan Parties to enter into the
Credit Agreement and to make loans to Borrower thereunder, and to extend such
credit to Borrower as the Loan Parties may from time-to-time agree to extend,
and for other good and valuable consideration, the receipt and legal sufficiency
of which are hereby acknowledged, Guarantor hereby guarantees payment of the
Guaranteed Debt (hereinafter defined) as more specifically described hereinbelow
in SECTION 1.03 and hereby agrees as follows:

                                  ARTICLE ___

                         NATURE AND SCOPE OF GUARANTY

     SECTION 1.01.  DEFINITION OF GUARANTEED DEBT.  As used herein, the term
"GUARANTEED DEBT" means:

Page 15
<PAGE>
 
     (a) All principal, interest, fees, reasonable attorneys' fees, commitment
fees, liabilities for costs and expenses, and other indebtedness, obligations,
and liabilities of Borrower to the Loan Parties at any time created or arising
in connection with the Credit Agreement, or any amendment thereto or
substitution therefor, including, but not limited to, all indebtedness,
obligations and liabilities of Borrower to the Loan Parties arising under the
Notes and under the other Loan Documents; and

     (b) All costs, expenses and fees, including, but not limited to court costs
and reasonable attorneys' fees, arising in connection with the collection of any
or all amounts, indebtedness, obligations and liabilities of Borrower to the
Loan Parties described in ITEM (A) of this SECTION 1.01.

     SECTION 1.02.  GUARANTEED DEBT NOT REDUCED BY OFFSET.  The indebtedness,
liabilities, obligations, and other Guaranteed Debt guaranteed hereby, and the
liabilities and obligations of Guarantor to the Loan Parties hereunder, shall
not be reduced, discharged, or released because or by reason of any existing or
future offset, claim, or defense of Borrower, or any other party, against any
Loan Party or against payment of the Guaranteed Debt, whether such offset, claim
or defense arises in connection with the Guaranteed Debt (or the transactions
creating the Guaranteed Debt) or otherwise.  Without limiting the foregoing or
Guarantor's liability hereunder, to the extent that any Loan Party advances
funds or extends credit to Borrower, and does not receive payments or benefits
thereon in the amounts and at the times required or provided by applicable
agreements or laws, Guarantor is absolutely liable to make such payments to (and
confer such benefits on) such Loan Party, on a timely basis.

     SECTION 1.03.   GUARANTY OF OBLIGATION.  Guarantor hereby irrevocably and
unconditionally guarantees to the Loan Parties (a) the due and punctual payment
of the Guaranteed Debt, and (b) the timely performance of all other obligations
now or hereafter owed by Borrower to the Loan Parties under the Credit
Agreement.  Guarantor hereby irrevocably and unconditionally covenants and
agrees that it is liable for the Guaranteed Debt as primary obligor.

     SECTION 1.04. NATURE OF GUARANTY. This Guaranty Agreement is intended to be
an irrevocable, absolute, continuing guaranty of payment and is not a guaranty
of collection. This Guaranty Agreement may not be revoked by Guarantor;
provided, however, if, according to applicable law, it shall ever be determined
or held that a guarantor under a continuing guaranty such as this Guaranty
Agreement shall have the absolute right, notwithstanding the express agreement
of such a guarantor otherwise, to revoke such guaranty as to Guaranteed Debt
which has then not yet arisen, then Guarantor may deliver to the Administrative
Agent written notice, in addition to giving such notice as provided in SECTION
5.02 hereof, that Guarantor will not be liable hereunder for any Guaranteed Debt
created, incurred, or arising after the giving of such notice, and such notice
will be effective as to Guarantor from and after (but not before) such times as
said written notice is actually delivered to, in addition to giving such notice
as provided in SECTION 5.02 hereof, and received by and receipted for in writing
by the Administrative Agent; provided that such notice shall not in anywise
affect, impair, or limit the liability and responsibility of any other person or
entity with respect to any Guaranteed Debt theretofore existing or thereafter
existing, arising, renewed, extended, or modified; provided, further, that such
notice shall not affect, impair, or release the liability and responsibility of
Guarantor with respect to Guaranteed Debt created, incurred, or arising (or in
respect of any Guaranteed Debt agreed or contemplated, in any respect, to be
created, whether advanced or not and whether committed to by the Loan Parties or
not, including, without limitation, any discretionary advances or extensions of
credit which may be made by any Loan Party at its option in the future under any
type of loan or credit agreement, arrangement or undertaking) prior to the
receipt of such notice by the Administrative Agent as aforesaid, or in respect
of any renewals, extensions, or modifications of such 

Page 16
<PAGE>
 
Guaranteed Debt, or in respect of interest or costs of collection thereafter
accruing on or with respect to such Guaranteed Debt, or with respect to
attorneys' fees thereafter becoming payable hereunder with respect to such
Guaranteed Debt, and shall continue to be effective with respect to any
Guaranteed Debt arising or created after any attempted revocation by Guarantor.
The fact that at any time or from time-to-time the Guaranteed Debt may be
increased, reduced, or paid in full shall not release, discharge, or reduce the
obligation of Guarantor with respect to indebtedness or obligations of Borrower
to the Loan Parties thereafter incurred (or other Guaranteed Debt thereafter
arising) under the Credit Agreement, the Notes, or otherwise. This Guaranty
Agreement may be enforced by the Loan Parties and any subsequent holder of the
Guaranteed Debt and shall not be discharged by the assignment or negotiation of
all or part of the Guaranteed Debt.

     SECTION 1.05.  PAYMENT BY GUARANTOR.  If all or any part of the Guaranteed
Debt shall not be punctually paid when due, whether at maturity or earlier by
acceleration or otherwise, then Guarantor shall, immediately upon demand by the
Administrative Agent, and without presentment, protest, notice of protest,
notice of nonpayment, notice of intention to accelerate or acceleration, or any
other notice whatsoever, pay in lawful money of the United States of America,
the amount due on the Guaranteed Debt to the Administrative Agent, for the
benefit of the Loan Parties, at the Administrative Agent's principal office in
Dallas, Texas.  Such demand(s) may be made at any time coincident with or after
the time for payment of all or part of the Guaranteed Debt, and may be made from
time-to-time with respect to the same or different items of Guaranteed Debt.
Such demand shall be deemed made, given and received in accordance with SECTION
5.02 hereof.

     SECTION 1.06.  PAYMENT OF EXPENSES.  In the event that Guarantor should
breach or fail to timely perform any provisions of this Guaranty Agreement, then
Guarantor shall, immediately upon demand by the Administrative Agent, pay to the
Administrative Agent, for the benefit of the Loan Parties, all costs and
expenses (including court costs and reasonable attorneys' fees) incurred by the
Loan Parties in the enforcement hereof or the preservation of the Loan Parties'
rights hereunder.  The covenant contained in this SECTION 1.06 shall survive the
payment of the Guaranteed Debt.

     SECTION 1.07.  NO DUTY TO PURSUE OTHERS.  It shall not be necessary for any
Loan Party (and Guarantor hereby waives any rights which Guarantor may have to
require any Loan Party), in order to enforce such payment by Guarantor, first to
(a) institute suit or exhaust its remedies against Borrower or others liable on
the Guaranteed Debt or any other person, (b) enforce the Loan Parties' rights
against any security which shall ever have been given to secure the Guaranteed
Debt, (c) enforce the Loan Parties's rights against any other guarantors of the
Guaranteed Debt, (d) join Borrower or any others liable on the Guaranteed Debt
in any action seeking to enforce this Guaranty Agreement, (e) exhaust any
remedies available to the Loan Parties against any security which shall ever
have been given to secure the Guaranteed Debt, or (e) resort to any other means
of obtaining payment of the Guaranteed Debt.  The Loan Parties shall not be
required to mitigate damages or take any other action to reduce, collect, or
enforce the Guaranteed Debt.  Further, Guarantor expressly waives each and every
right to which it may be entitled by virtue of the suretyship law of the State
of Texas, including without limitation, any rights pursuant to Rule 31, Texas
Rules of Civil Procedure, Articles 1986 and 1987, Revised Civil Statutes of
Texas and Chapter 34 of the Texas Business and Commerce Code.

     SECTION 1.08. WAIVER OF NOTICES, ETC. Guarantor agrees to the provisions of
the Credit Agreement, the Notes, and the other Loan Documents, and hereby waives
notice of (a) any loans or advances made by any Loan Party to Borrower, (b)
acceptance of this Guaranty Agreement, (c) any

Page 17
<PAGE>
 
amendment or extension of the Credit Agreement, the Notes, the other Loan
Documents, or any other instrument or document pertaining to all or any part of
the Guaranteed Debt, (d) the execution and delivery by Borrower and any Loan
Party of any other loan or credit agreement or of Borrower's execution and
delivery of any promissory notes or other documents in connection therewith, (e)
the occurrence of any Default or Potential Default, (f) any Loan Party's
transfer or disposition of the Guaranteed Debt, or any part thereof, (g) sale or
foreclosure (or posting or advertising for sale or foreclosure) of any
collateral for the Guaranteed Debt, (h) protest, proof of nonpayment, or default
by Borrower, or (i) any other action at any time taken or omitted by any Loan
Party, and, generally, all demands and notices of every kind in connection with
this Guaranty Agreement, the Credit Agreement, the Notes, the other Loan
Documents, and any documents or agreements evidencing, securing or relating to
any of the Guaranteed Debt and the obligations hereby guaranteed.

     SECTION 1.09.  EFFECT OF BANKRUPTCY, OTHER MATTERS.  In the event that,
pursuant to any insolvency, bankruptcy, reorganization, receivership, or other
debtor relief law, or any judgment, order, or decision thereunder, or for any
other reason, (a) any Loan Party must rescind or restore any payment, or any
part thereof, received by such Loan Party in satisfaction of the Guaranteed
Debt, as set forth herein, any prior release or discharge from the terms of this
Guaranty Agreement given to Guarantor by such Loan Party shall be without
effect, and this Guaranty Agreement shall remain in full force and effect, (b)
Borrower shall cease to be liable to the Loan Parties for any of the Guaranteed
Debt (other than by reason of the indefeasible payment in full thereof by
Borrower), the obligations of Guarantor under this Guaranty Agreement shall
remain in full force and effect.  It is the intention of the Loan Parties and
Guarantor that Guarantor's obligations hereunder shall not be discharged except
by Guarantor's performance of such obligations and then only to the extent of
such performance.  Without limiting the generality of the foregoing, it is the
intention of the Loan Parties and Guarantor that the filing of any bankruptcy or
similar proceeding by or against Borrower or any other person or party obligated
on any portion of the Guaranteed Debt shall not affect the obligations of
Guarantor under this Guaranty Agreement or the rights of the Loan Parties under
this Guaranty Agreement, including, without limitation, the right or ability of
the Loan Parties to pursue or institute suit against Guarantor for the entire
Guaranteed Debt.

                                  ARTICLE II

               ADDITIONAL EVENTS AND CIRCUMSTANCES NOT REDUCING
                    OR DISCHARGING GUARANTOR'S OBLIGATIONS

     Guarantor hereby consents and agrees to each of the following, and agrees
that Guarantor's obligations under this Guaranty Agreement shall not be
released, diminished, impaired, reduced, or adversely affected by any of the
following, and waives any common law, equitable, statutory or other rights
(including without limitation rights to notice) which Guarantor might otherwise
have as a result of or in connection with any of the following:

     SECTION 2.01.  MODIFICATIONS, ETC.  Any renewal, extension, increase,
modification, alteration, or rearrangement of all or any part of the Guaranteed
Debt, or of the Credit Agreement, the Notes, or any other Loan Document;

     SECTION 2.02.  ADJUSTMENT, ETC.  Any adjustment, indulgence, forbearance,
or compromise that might be granted or given by any Loan Party to Borrower or
Guarantor;

Page 18
<PAGE>
 
     SECTION 2.03. CONDITION, COMPOSITION OR STRUCTURE OF BORROWER OR GUARANTOR.
The insolvency, bankruptcy, arrangement, adjustment, composition, structure,
liquidation, disability, dissolution, or lack of power of Borrower or any other
party at any time liable for the payment of all or part of the Guaranteed Debt;
or any dissolution of Borrower or Guarantor, or any sale, lease or transfer of
any or all of the assets of Borrower or Guarantor, or any changes in name,
business, location, composition, structure, or changes in the shareholders,
partners, or members (whether by accession, secession, cessation, death,
dissolution, transfer of assets, or other matter) of Borrower or Guarantor; or
any reorganization of Borrower or Guarantor;

     SECTION 2.04.  INVALIDITY OF GUARANTEED DEBT.  The invalidity, illegality,
or unenforceability of all or any part of the Guaranteed Debt, or any document
or agreement executed in connection with the Guaranteed Debt, for any reason
whatsoever, including without limitation the fact that (a) the Guaranteed Debt,
or any part thereof, exceeds the amount permitted by law, (b) the act of
creating the Guaranteed Debt or any part thereof is ultra vires, (c) the
officers or representatives executing the Credit Agreement, the Notes, the other
Loan Documents, or other documents or otherwise creating the Guaranteed Debt
acted in excess of their authority, (d) the Guaranteed Debt violates applicable
usury laws, (e) Borrower has valid defenses, claims, or offsets (whether at law,
in equity, or by agreement) which render the Guaranteed Debt wholly or partially
uncollectible from Borrower, (f) the creation, performance, or repayment of the
Guaranteed Debt (or the execution, delivery, and performance of any document or
instrument representing part of the Guaranteed Debt or executed in connection
with the Guaranteed Debt, or given to secure the repayment of the Guaranteed
Debt) is illegal, uncollectible, or unenforceable, or (g) the Credit Agreement,
the Notes, the other Loan Documents, or other documents or instruments
pertaining to the Guaranteed Debt have been forged or otherwise are irregular or
not genuine or authentic.

     SECTION 2.05.  RELEASE OF OBLIGORS.  Any full or partial release of the
liability of Borrower on the Guaranteed Debt or any part thereof, or of any co-
guarantors, or any other person or entity now or hereafter liable, whether
directly or indirectly, jointly, severally, or jointly and severally, to pay,
perform, guarantee, or assure the payment of the Guaranteed Debt or any part
thereof, it being recognized, acknowledged and agreed by Guarantor that
Guarantor may be required to pay the Guaranteed Debt in full without assistance
or support of any other party, and Guarantor has not been induced to enter into
this Guaranty Agreement on the basis of a contemplation, belief, understanding,
or agreement that other parties will be liable to perform the Guaranteed Debt,
or that the Loan Parties will look to other parties to perform the Guaranteed
Debt; notwithstanding the foregoing, Guarantor does not hereby waive or release
(expressly or impliedly) any rights of subrogation, reimbursement, or
contribution which it may have, after payment in full of the Guaranteed Debt,
against others liable on the Guaranteed Debt; Guarantor's rights of subrogation
and reimbursement are, however, subordinate to the rights and claims of the Loan
Parties;

     SECTION 2.06.  OTHER SECURITY. The taking or accepting of any other
security, collateral, or guaranty, or other assurance of payment, for all or any
part of the Guaranteed Debt;

     SECTION 2.07.  RELEASE OF COLLATERAL, ETC.  Any release, surrender,
exchange, subordination, deterioration, waste, loss, or impairment (including
without limitation negligent, willful, unreasonable, or unjustifiable
impairment) of any collateral, property, or security, at any time existing in
connection with, or assuring or securing payment of, all or any part of the
Guaranteed Debt;

     SECTION 2.08. CARE AND DILIGENCE. The failure of any Loan Party or any
other party to exercise

Page 19
<PAGE>
 
diligence or reasonable care or act, fail to act, or comply with any duty in the
administration, preservation, protection, enforcement, sale application,
disposal, or other handling or treatment of all or any part of Guaranteed Debt
or any collateral, property, or security at any time securing any portion
thereof, including, without limiting the generality of the foregoing, the
failure to conduct any foreclosure or other remedy fairly, in a commercially
reasonable manner, or in such a way so as to obtain the best possible price or a
favorable price or otherwise act or fail to act;

     SECTION 2.09.  STATUS OF LIENS.  The fact that any collateral, security,
security interest, or lien contemplated or intended to be given, created, or
granted as security for the repayment of the Guaranteed Debt shall not be
properly perfected or created, or shall prove to be unenforceable or subordinate
to any other security interest or lien, it being recognized and agreed by
Guarantor that Guarantor is not entering into this Guaranty Agreement in
reliance on, or in contemplation of the benefits of, the validity,
enforceability, collectibility, or value of any of the collateral for the
Guaranteed Debt; notwithstanding the foregoing, Guarantor does not hereby waive
or release (expressly or impliedly) any right to be subrogated to the rights of
the Loan Parties in any collateral or security for the Guaranteed Debt after
payment in full of the Guaranteed Debt; Guarantor's rights of subrogation are,
however, subordinate to the rights, claims, liens and security interests of the
Loan Parties;

     SECTION 2.10.  OFFSET.  Any existing or future right of offset, claim, or
defense of Borrower against the Loan Parties, or any other party, or against
payment of the Guaranteed Debt, whether such right of offset, claim, or defense
arises in connection with the Guaranteed Debt (or the transactions creating the
Guaranteed Debt) or otherwise;

     SECTION 2.11.  MERGER.  The reorganization, merger, or consolidation of
Borrower or Guarantor into or with any other corporation or entity;

     SECTION 2.12.  PREFERENCE.  Any payment by Borrower to any Loan Party is
held to constitute a preference under bankruptcy laws, or for any reason any
Loan Party is required to refund such payment or pay such amount to Borrower or
someone else; or

     SECTION 2.13.  OTHER ACTIONS TAKEN OR OMITTED.  Any other action taken or
omitted to be taken with respect to the Credit Agreement, the Guaranteed Debt,
or the security and collateral therefor, whether or not such action or omission
prejudices Guarantor or increases the likelihood or risk that Guarantor will be
required to pay the Guaranteed Debt pursuant to the terms hereof; it is the
unambiguous and unequivocal intention of Guarantor that Guarantor shall be
obligated to pay the Guaranteed Debt when due, notwithstanding any occurrence,
circumstance, event, action, or omission whatsoever, whether contemplated or
uncontemplated, and whether or not otherwise or particularly described herein,
except for the full and final payment and satisfaction of the Guaranteed Debt.

                                  ARTICLE III

                        REPRESENTATIONS AND WARRANTIES

     To induce the Loan Parties to enter into the Credit Agreement and extend
credit to Borrower, Guarantor represents and warrants to the Loan Parties that:

     SECTION 3.01.  BENEFIT.  Guarantor has received, or will receive, direct or
indirect benefit from the 

Page 20
<PAGE>
 
making of this Guaranty and the Guaranteed Debt; 

     SECTION 3.02. FAMILIARITY AND RELIANCE. Guarantor is familiar with, and has
independently reviewed books and records regarding, the financial condition of
Borrower and is familiar with the value of any and all collateral intended to be
created as security for the payment of the Guaranteed Debt; however, Guarantor
is not relying on such financial condition or the collateral as an inducement to
enter into this Guaranty Agreement;

     SECTION 3.03.  NO REPRESENTATION BY THE LOAN PARTIES.  No Loan Party or any
other party has made any representation, warranty, or statement to Guarantor in
order to induce Guarantor to execute this Guaranty Agreement;

     SECTION 3.04.  GUARANTOR'S FINANCIAL CONDITION.  As of the date hereof, and
after giving effect to this Guaranty Agreement and the contingent obligation
evidenced hereby, Guarantor is, and will be, solvent, and has and will have
assets which, fairly valued, exceed its obligations, liabilities, and debts;

     SECTION 3.05.  DIRECTORS' DETERMINATION OF BENEFIT.  The Board of Directors
of Guarantor, acting pursuant to a duly called and constituted meeting, after
proper notice, or pursuant to a valid unanimous consent, has determined that
this Guaranty directly or indirectly benefits Guarantor and is in the best
interests of Guarantor;

     SECTION 3.06.  LEGALITY.  The execution, delivery, and performance by
Guarantor of this Guaranty Agreement and the consummation of the transactions
contemplated hereunder (a) have been duly authorized by all necessary trust
action of Guarantor, and (b) do not, and will not, contravene or conflict with
any law, statute or regulation whatsoever to which Guarantor is subject or
constitute a default (or an event which with notice or lapse of time or both
would constitute a default) under, or result in the breach of, any indenture,
mortgage, deed of trust, charge, lien, or any contract, agreement, or other
instrument to which Guarantor is a party or which may be applicable to Guarantor
or any of its assets, or violate any provisions of its Trust Agreement, Bylaws,
or any other organizational document of Guarantor; this Guaranty Agreement is a
legal and binding obligation of Guarantor and is enforceable in accordance with
its terms, except as limited by bankruptcy, insolvency or other laws of general
application relating to the enforcement of creditors' rights; and

     SECTION 3.08.  SURVIVAL.  All representations and warranties made by
Guarantor herein shall survive the execution hereof.

                                  ARTICLE IV

                     SUBORDINATION OF CERTAIN INDEBTEDNESS

     SECTION 4.01.  SUBORDINATION OF GUARANTOR CLAIMS.  As used herein, the term
"GUARANTOR CLAIMS" shall mean all debts and liabilities of Borrower to
Guarantor, whether such debts and liabilities now exist or are hereafter
incurred or arise, or whether the obligations of Borrower thereon be direct,
contingent, primary, secondary, several, joint and several, or otherwise, and
irrespective of whether such debts or liabilities be evidenced by note,
contract, open account, or otherwise, and irrespective of the person or persons
in whose favor such debts or liabilities may, at their inception, have been, or
may hereafter be created, or the manner in which they have been or may hereafter
be acquired by Guarantor.  The Guarantor 

Page 21
<PAGE>
 
Claims shall include without limitation all rights and claims of Guarantor
against Borrower (arising as a result of subrogation or otherwise) as a result
of Guarantor's payment of all or a portion of the Guaranteed Debt. Until the
Guaranteed Debt shall be paid and satisfied in full and Guarantor shall have
performed all of its obligations hereunder, if a Potential Default or Default
exists, then Guarantor shall not receive or collect, directly or indirectly,
from Borrower or any other party any amount upon the Guarantor Claims.

     SECTION 4.02. CLAIMS IN BANKRUPTCY. In the event of receivership,
bankruptcy, reorganization, arrangement, debtor's relief, or other insolvency
proceedings involving Borrower as debtor, the Loan Parties shall have the right
to prove its claim in any such proceeding so as to establish its rights
hereunder and receive directly from the receiver, trustee, or other court
custodian dividends and payments which would otherwise be payable upon Guarantor
Claims. Guarantor hereby assigns such dividends and payments to the Loan
Parties. Should any Loan Party receive, for application upon the Guaranteed
Debt, any such dividend or payment which is otherwise payable to Guarantor, and
which, as between Borrower and Guarantor, shall constitute a credit upon the
Guarantor Claims, then upon payment to the Loan Parties in full of the
Guaranteed Debt, Guarantor shall become subrogated to the rights of the Loan
Parties to the extent that such payments to the Loan Parties on the Guarantor
Claims have contributed toward the liquidation of the Guaranteed Debt, and such
subrogation shall be with respect to that proportion of the Guaranteed Debt
which would have been unpaid if the Loan Parties had not received dividends or
payments upon the Guarantor Claims.

     SECTION 4.03.  PAYMENTS HELD IN TRUST.  In the event that, notwithstanding
SECTIONS 4.01 and 4.02 above, Guarantor should receive any funds, payment, claim
or distribution which is prohibited by such Sections, Guarantor agrees to hold
in trust for the Loan Parties, in kind, all funds, payments, claims, or
distributions so received, and agrees that he shall have absolutely no dominion
over such funds, payments, claims, or distributions so received except to pay
them promptly to the Administrative Agent, for the benefit of the Loan Parties,
and Guarantor covenants promptly to pay the same to the Administrative Agent,
for the benefit of the Loan Parties.

     SECTION 4.04.  LIENS SUBORDINATE.  Guarantor agrees that any liens,
security interests, judgment liens, charges, or other encumbrances upon
Borrower's assets securing payment of the Guarantor Claims shall be and remain
inferior and subordinate to any liens, security interests, judgment liens,
charges, or other encumbrances upon Borrower's assets securing payment of the
Guaranteed Debt, regardless of whether such encumbrances in favor of Guarantor
or the Loan Parties presently exist or are hereafter created or attach.  Without
the prior written consent of the Administrative Agent, Guarantor shall not (a)
exercise or enforce any creditor's right it may have against Borrower, or (b)

                             REVOLVING CREDIT NOTE

$_____________________           Dallas, Texas          As of ____________, 1996


     1.  FOR VALUE RECEIVED, PRENTISS PROPERTIES ACQUISITION PARTNERS, L.P., a
Delaware limited partnership ("MAKER"), hereby unconditionally promises to pay
to the order of __________ ("PAYEE"), at the address of the Administrative Agent
(defined below) set forth in the Credit Agreement defined below, the sum of
_________________________ Dollars ($ _______________________________) (or, if
less, so much thereof as may be advanced), in lawful money of the United States
of America.  Capitalized terms not defined herein shall have the meaning
assigned to those terms in the Credit Agreement.

     2.  The unpaid principal amount of, and accrued unpaid interest on, this
Note is payable in accordance with the Credit Agreement.

     3.  The unpaid principal balance advanced and outstanding hereunder shall
bear interest from the date of advance until maturity at the rate per annum
provided in the Credit Agreement that is selected by Maker pursuant to the
Credit Agreement.  The interest rate specified in this section is subject to
adjustment under the circumstances described in the Credit Agreement.  Interest
shall be computed in the manner provided in the Credit Agreement.

     4.  Notwithstanding any provision contained in this Note or any other
document executed or delivered in connection with this Note or in connection
with the Credit Agreement, Payee shall never be deemed to have contracted for or
be entitled to receive, collect or apply as interest on this Note, any amount in
excess of the maximum rate of interest permitted to be charged by applicable
law, and, if Payee ever receives, collects or applies as interest any such
excess, then the amount that would be excessive interest shall be applied to
reduce the unpaid principal balance of this Note, and, if the principal balance
of this Note is paid in full by that application, then any remaining excess
shall promptly be paid to Maker.  In determining whether the interest paid or
payable under any specific contingency exceeds the highest lawful rate, Maker
and Payee shall, to the maximum extent permitted under applicable law, (a)
characterize any non-principal payment (other than payments expressly designated
as interest payments hereunder) as an expense or fee rather than as interest,
(b) exclude voluntary prepayments and the effect thereof, and (c) spread the
total amount of interest throughout the entire contemplated term of this Note so
that the interest rate is uniform throughout that term.

     5.  This Note has been executed and delivered pursuant to a Credit
Agreement (as modified, amended, renewed or extended, the "CREDIT AGREEMENT")
dated as of October 17, 1996, executed by and between Maker, Bank One, Texas,
N.A., as Administrative Agent (together with any successor or assigns, the
"ADMINISTRATIVE AGENT"), NationsBank of Texas, N.A., as Documentation Agent,
Payee, and the Lenders defined therein, and is one of the "Notes" referred to
therein, and the holder of this Note is entitled to the benefits provided in the
Credit Agreement.  Reference is hereby made to the Credit Agreement for a
statement of (a) the obligation of Payee to advance funds hereunder, (b) the
prepayment rights and obligations of Maker, and (c) the events upon which the
maturity of this Note may be accelerated.

     6.   If the principal of, or any installment of interest on, this Note
becomes due and payable on a day other than a Business Day, then the maturity
thereof shall be extended to the next succeeding Business Day. If this Note, or
any installment or payment due hereunder, is not paid when due, whether at

Page 26
<PAGE>
 
maturity or by acceleration, or if it is collected through a bankruptcy, probate
or other court, whether before or after maturity, then Maker shall pay all costs
of collection, including, but not limited to, reasonable attorneys' fees
incurred by the holder of this Note. All past due principal of, and to the
extent permitted by applicable law, interest on this Note shall bear interest
until paid at the rate provided in the Credit Agreement.

     7.  Except as expressly provided in the Credit Agreement, Maker and all
sureties, endorsers, guarantors and other parties ever liable for payment of any
sums payable pursuant to the terms of this Note, jointly and severally waive
demand, presentment for payment, protest, notice of protest, notice of
acceleration, notice of intent to accelerate, diligence in collection, the
bringing of any suit against any party and any notice of or defense on account
of any extensions, renewals, partial payments or changes in any manner of or in
this Note or in any of its terms, provisions and covenants, or any releases or
substitutions of any security, or any delay, indulgence or other act of any
trustee or any holder hereof, whether before or after maturity.

     8.  All Borrowings made by Payee, the respective Interest Periods thereof
(if applicable), and all repayments of the principal thereof may be recorded by
Payee and, before any transfer hereof, endorsed by Payee on the schedule
attached hereto, or on a continuation of the schedule attached to and a part
hereof, provided that the failure of Payee to record any endorsement shall not
affect the obligation of Maker hereunder or under the Credit Agreement.

     9.  This Note is being executed and delivered, and is intended to be
performed in the State of Texas.  Except to the extent that the laws of the
United States may apply to the terms hereof, the substantive laws of the State
of Texas shall govern the validity, construction, enforcement and interpretation
of this Note.

and other benefits of the Premises and the Accessories (without derogation of
ARTICLE 3 hereof); (vi) oil, gas, and other hydrocarbons and other minerals
produced from or allocated to the Land and all products processed or obtained
therefrom, and the proceeds thereof; and (vii) engineering, accounting, title,
legal, and other technical or business data concerning the Mortgaged Property
which are in the possession of Grantor or in which Grantor can otherwise grant a
security interest; and (d) all right, title, and interest of Grantor in and to
the following:  (i) proceeds of or arising from the properties, rights, titles,
and interests referred to above in this SECTION 1.2, including but not limited
to proceeds of any sale, lease, or other disposition thereof, proceeds of each
policy of insurance relating thereto (including premium refunds), proceeds of
the taking thereof or of any rights appurtenant thereto, including change of
grade of streets, curb cuts, or other rights of access, by eminent domain or
transfer in lieu thereof for public or quasi-public use under any law, and
proceeds arising out of any damage thereto; and (ii) other interests of every
kind and character which Grantor now has or hereafter acquires in, to or for the
benefit of the properties, rights, titles and interests referred to above in
this SECTION 1.2 and all property used or useful in connection therewith,
including but not limited to rights of ingress and egress and remainders,
reversions, and reversionary rights or interests; and if the estate of Grantor
in any of the property referred to above in this SECTION 1.2 is a leasehold
estate, this conveyance shall include, and the lien and security interest
created hereby shall encumber and extend to, all other or additional title,
estates, interests, or rights which are now owned or may hereafter be acquired
by Grantor in or to the property demised under the lease creating the leasehold
estate; TO HAVE AND TO HOLD the foregoing rights, interests and properties, and
all rights, estates, powers, and privileges appurtenant thereto (herein
collectively called the "MORTGAGED PROPERTY"), unto Trustee, and his successors
or substitutes in this trust, and to his or their successors and assigns, in
trust, however, upon the terms, provisions, and conditions herein set forth.

     Section 1.3.  SECURITY INTEREST.  Grantor hereby grants to Agent, for the
ratable benefit of Holders (as hereinafter defined), a security interest in all
of the Mortgaged Property which constitutes personal property or fixtures
(herein sometimes collectively called the "COLLATERAL").  In addition to its
rights hereunder or otherwise, Agent, on behalf of Holders, shall have all of
the rights of a secured party 
<PAGE>
 
under the Texas Business and Commerce Code, or under the Uniform Commercial Code
in force in any other state to the extent the same is applicable law.

     Section 1.4.  NOTE, LOAN DOCUMENTS, OTHER OBLIGATIONS.  This Deed of Trust
is made to secure and enforce the payment and performance of the following
promissory notes, obligations, indebtedness, and liabilities and all renewals,
extensions, supplements, increases, and modifications thereof in whole or in
part from time-to-time:  (a) the Promissory Notes and all other notes given in
substitution therefor or in modification, supplement, increase, renewal, or
extension thereof, in whole or in part (such note or notes, whether one or more,
as from time-to-time renewed, extended, supplemented, increased, or modified and
all other notes given in substitution therefor, or in modification, renewal, or
extension thereof, in whole or in part, being hereinafter called the "NOTES,"
and the Lenders, or the subsequent holder at the time in question of any Note or
any of the secured indebtedness, as hereinafter defined, being herein
individually called "HOLDERS" and collectively called "HOLDERS"); (b) all
indebtedness and other obligations owed by Borrower to Agent and Holders now or
hereafter incurred or arising pursuant to or permitted by the provisions of the
Credit Agreement, the Notes, this Deed of Trust, or any other document now or
hereafter evidencing, governing, guaranteeing, securing, or otherwise executed
in connection with the loan evidenced by the Credit Agreement and the Notes (the
Credit Agreement, the Notes, this Deed of Trust, and such other documents, as
they or any of them may have been or may be from time-to-time renewed, extended,
supplemented, increased, or modified, being herein sometimes collectively called
the "LOAN DOCUMENTS"); and (c) all other loans and future advances made by Agent
and/or Holders to Borrower pursuant to the Loan Documents and all other debts,
obligations, and liabilities of Borrower of every kind and character now or
hereafter existing in favor of Agent and/or Holders, whether direct or indirect,
primary or secondary, joint or several, fixed or contingent, secured or
unsecured, arising under the Credit Agreement, it being contemplated that
Borrower may hereafter become indebted to Agent and/or Holders for such further
debts, obligations, and liabilities pursuant to the Loan Documents; provided,
however, and notwithstanding the foregoing provisions of this clause (c), this
Deed of Trust shall not secure any such other loan, advance, debt, obligation,
or liability with respect to which Holder is by applicable law prohibited from
obtaining a lien on real estate nor shall this clause (c) operate or be
effective to constitute or require any assumption or payment by any person, in
any way, of any debt of any other person to the extent that the same would
violate or exceed the limit provided in any applicable usury or other law.  The
indebtedness referred to in this SECTION 1.4 is hereinafter sometimes referred
to as the "SECURED INDEBTEDNESS" or the "INDEBTEDNESS SECURED HEREBY."


                                   ARTICLE 2

                   REPRESENTATIONS, WARRANTIES AND COVENANTS


     Section 2.1.  Grantor represents, warrants, and covenants as follows:

     (a) PERFORMANCE.  Grantor will timely and properly perform and comply with
all of the covenants, agreements, and conditions imposed upon it by this Deed of
Trust and the other Loan Documents and will not permit a default to occur
hereunder or thereunder.  Time shall be of the essence in this Deed of Trust.

     (b) TITLE AND PERMITTED ENCUMBRANCES. Grantor has, in Grantor's own right,
and Grantor covenants to maintain, lawful, good and indefeasible title to the
Mortgaged Property, free and clear of all liens, charges, claims, security
interests, and encumbrances except for (i) the matters, if any, set forth on
EXHIBIT B hereto, which are Permitted Encumbrances only to the extent the same
are valid and subsisting

Page 35
<PAGE>
 
and affect the Mortgaged Property, (ii) the liens and security interests
evidenced by this Deed of Trust, (iii) statutory liens for ad valorem taxes and
standby fees on the Mortgaged Property which are not yet delinquent, (iv) other
liens and security interests (if any) in favor of Lender, and (v) Permitted
Liens (as defined in the Credit Agreement) (the matters described in the
foregoing clauses (i), (ii), (iii), (iv), and (v) being herein called the
"PERMITTED ENCUMBRANCES"). Grantor, and Grantor's successors and assigns, will
warrant and forever defend title to the Mortgaged Property, subject as aforesaid
to Trustee and his successors or substitutes and assigns, against the claims and
demands of all persons claiming or to claim the same or any part thereof.
Grantor will punctually pay, perform, observe, and keep all covenants,
obligations, and conditions in or pursuant to any Permitted Encumbrance and will
not modify or permit modification of any Permitted Encumbrance without the prior
written consent of Agent. Inclusion of any matter as a Permitted Encumbrance
does not constitute approval or waiver by Agent of any existing or future
violation or other breach thereof by Grantor, by the Mortgaged Property or
otherwise. If any right or interest of Agent or Holders in the Mortgaged
Property or any part thereof shall be endangered or questioned or shall be
attacked directly or indirectly, Trustee, Agent, and Holders, or any of them
(whether or not named as parties to legal proceedings with respect thereto), are
hereby authorized and empowered to take such steps as in their discretion may be
proper for the defense of any such legal proceedings or the protection of such
right or interest of Agent or Holders, including but not limited to the
employment of independent counsel, the prosecution or defense of litigation, and
the compromise or discharge of adverse claims. All expenditures so made of every
kind and character shall be due and payable upon demand (which obligation
Grantor hereby promises to pay) owing by Grantor to Agent, Holders or Trustee
(as the case may be), and the party (Agent, Holders or Trustee, as the case may
be) making such expenditures shall be subrogated to all rights of the person
receiving such payment. Agent, Holders, or Trustee (as the case may be) shall
exercise their reasonable best efforts to notify Grantor prior to taking any
such steps or incurring any such expenditures, except in the case of exigent
circumstances.

     (c) TAXES AND OTHER IMPOSITIONS.  Except to the extent of reserves required
pursuant to SECTION 2.1(E), Grantor will pay, or cause to be paid, prior to
delinquency all taxes, assessments, and other charges or levies imposed upon or
against or with respect to the Mortgaged Property or the ownership, use,
occupancy or enjoyment of any portion thereof, or any utility service thereto,
including but not limited to all ad valorem taxes assessed against the Mortgaged
Property or any part thereof, and shall deliver promptly to Holder such evidence
of the payment thereof as Agent may require, except that Grantor may contest
taxes, assessments, and other charges or levies in good faith by appropriate
proceedings if Grantor has established reserves in accordance with GAAP or
obtained other security (in each case reasonably acceptable to Agent).

     (d) INSURANCE. Grantor shall obtain and maintain at Grantor's sole expense:
(1) mortgagee title insurance issued to Agent, for the benefit of Holders,
covering the Premises as required by Agent; (2) all-risk insurance with respect
to all insurable Mortgaged Property, against loss or damage by fire, lightning,
windstorm, explosion, hail, tornado and such hazards as are presently included
in so-called "all-risk" coverage and against such other insurable hazards as
Agent may require, in an amount not less than 100% of the full replacement cost
(exclusive of costs of excavations, foundations, underground utilities and
footings), including the cost of debris removal, without deduction for
depreciation and sufficient to prevent Grantor and Agent from becoming a
coinsurer, such insurance to be in Builder's Risk (nonreporting) form during and
with respect to any construction on the Premises; (3) if and to the extent any
portion of the Premises is in a special flood hazard area, a flood insurance
policy in an amount equal to the lesser of the aggregate principal face amount
of the Notes or the amount required by Agent; (4) comprehensive general public
liability insurance, on an "occurrence" basis, for the benefit of Grantor,
Agent, and Holders as additional named insureds; (5) statutory workers'
compensation insurance with respect to any work on or about the Premises; and
(6) such other insurance on the Mortgaged Property as may from time-to-time be
reasonably required by Agent and against other insurable hazards or casualties
which at the time are commonly insured against in the case of premises similarly
situated, due regard being given to the height, type, construction, location,
use, and occupancy of buildings and improvements. All

Page 36
<PAGE>
 
insurance policies shall be issued and maintained by insurers, in amounts, with
deductibles, and in form reasonably satisfactory to Agent, and shall require not
less than thirty (30) days' prior written notice to Agent of any cancellation or
change of coverage. All insurance policies maintained, or caused to be
maintained, by Grantor with respect to the Mortgaged Property, except for public
liability insurance, shall provide that each such policy shall be primary
without right of contribution from any other insurance that may be carried by
Grantor or Agent and that all of the provisions thereof, except the limits of
liability, shall operate in the same manner as if there were a separate policy
covering each insured. If any insurer which has issued a policy of title,
hazard, liability, or other insurance required pursuant to this Deed of Trust or
any other Loan Document becomes insolvent or the subject of any bankruptcy,
receivership or similar proceeding or if in Agent's reasonable opinion the
financial responsibility of such insurer is or becomes inadequate, Grantor
shall, in each instance promptly upon the request of Agent and at Grantor's
expense, obtain and deliver to Agent a like policy (or, if and to the extent
permitted by Agent, a certificate of insurance) issued by another insurer, which
insurer and policy meet the requirements of this Deed of Trust or such other
Loan Document, as the case may be. Without limiting the discretion of Agent with
respect to required endorsements to insurance policies, all such policies for
loss of or damage to the Mortgaged Property shall contain a standard mortgage
clause (without contribution) naming Agent as mortgagee with loss proceeds
payable to Agent, for the benefit of Lenders, notwithstanding: (i) any act,
failure to act, or negligence of or violation of any warranty, declaration, or
condition contained in any such policy by any named insured; (ii) the occupation
or use of the Mortgaged Property for purposes more hazardous than permitted by
the terms of any such policy; (iii) any foreclosure or other action by Agent or
any Holder under the Loan Documents; or (iv) any change in title to or ownership
of the Mortgaged Property or any portion thereof, such proceeds to be held for
application as provided in the Loan Documents. A copy of the original policy and
a satisfactory certificate of insurance shall be delivered to Agent at the time
of execution of this Deed of Trust, with premiums fully paid, and each renewal
or substitute policy (or certificate) shall be delivered to Agent, with premiums
fully paid, at least ten (10) days before the termination of the policy it
renews or replaces. Grantor shall pay all premiums on policies required
hereunder as they become due and payable and promptly deliver to Agent evidence
satisfactory to Agent of the timely payment thereof. If any loss occurs at any
time when Grantor has failed to perform Grantor's covenants and agreements in
this paragraph, Agent, for the benefit of Holders, shall nevertheless be
entitled to the benefit of all insurance covering the loss and held by or for
Grantor, to the same extent as if it had been made payable to Agent. While a
default exists, Agent shall have the right (but not the obligation) to make
proof of loss for, settle, and adjust any claim under, and receive the proceeds
of, all insurance for loss of or damage to the Mortgaged Property, and the
expenses incurred by Agent in the adjustment and collection of insurance
proceeds shall be a part of the secured indebtedness and shall be due and
payable to Agent on demand. Agent shall not be, under any circumstances, liable
or responsible for the obtaining, maintaining, or adequacy of any insurance or
for failure to collect or exercise diligence in the collection of any of such
proceeds or for failure to see to the proper application of any amount paid over
to Grantor. Any such proceeds received by Agent shall, after deduction therefrom
of all reasonable expenses actually incurred by Agent, including reasonable
attorneys' fees, at Agent's option be (1) released to Grantor, or (2) applied
(upon compliance with such terms and conditions as may be required by Agent) to
repair or restoration, either partly or entirely, of the Mortgaged Property so
damaged, or (3) applied to the payment of the secured indebtedness in such order
and manner as provided in the Credit Agreement, whether or not due. In any
event, the unpaid portion of the secured indebtedness shall remain in full force
and effect and the payment thereof shall not be excused. Grantor shall at all
times comply with the requirements of the insurance policies required hereunder
and of the issuers of such policies and of any board of fire underwriters or
similar body as applicable to or affecting the Mortgaged Property.

     If there is loss or damage to the Mortgaged Property, then the Mortgaged
Property may, at the request of Grantor, be removed from the Borrowing Base (as
defined in the Credit Agreement) and all or a portion of the insurance proceeds
shall be delivered to Grantor, so long as, after giving effect to such removal
and delivery of insurance proceeds, no default exists and the remaining
Borrowing Base exceeds the Obligation (as defined in the Credit Agreement).

Page 37
<PAGE>
 
     Subject to the immediately preceding paragraph, if there is loss or damage
to the Mortgaged Property, then Agent shall, on behalf of Holders, use such
insurance proceeds to allow Grantor, upon Grantor's written request within
twenty (20) days of a loss, to restore or rebuild the Mortgaged Property,
provided that all of the following conditions are satisfied: (i) Agent
determines, in its reasonable discretion, that it is economically, financially,
and practically feasible to repair and restore the Mortgaged Property to
substantially the same character as prior to such damage or destruction on or
before sixty (60) days prior to the Termination Date (as defined in the Credit
Agreement), which must be a date not more than six (6) months following the date
such insurance proceeds are received by Agent; (ii) the total cost of repairing
and restoring the Mortgaged Property to its previous condition, as estimated by
an consultant approved by Agent, shall not be greater than the amount of such
insurance proceeds together with any sums that Grantor deposits with Agent in
advance for the purpose of paying for the cost of such repairs and restoration;
(iii) such restoration and repair shall be accomplished in accordance with the
requirements and conditions relating to advancement and disbursement of funds
determined by Agent; (iv) no default exists; and (v) Grantor shall provide Agent
with evidence that the loss or damage to the Mortgaged Property will not result
in termination of the tenancy of the existing tenants in the Mortgaged Property
occupying more than thirty-three and one-third percent (33-1/3%) of the rentable
square footage of the Mortgaged Property, including, if requested by Agent,
appropriate estoppel letters from such tenants and/or evidence that Grantor has
obtained substitute tenants.  The Mortgaged Property shall be repaired and
restored so as to be of at least equal value in substantially the same character
as prior to such damage or destruction.  Notwithstanding the foregoing, Lender
shall have no obligation to Borrower to provide such proceeds to restore the
Mortgaged Property if the sums referred to in (ii) are not sufficient to pay the
costs of the restoration.

     If such proceeds are made available by Agent to Grantor, any surplus which
may remain out of said insurance proceeds after payment of all costs and
expenses of such repair and restoration shall, at the option of Lender, be
applied first, to any expenses payable by Grantor pursuant to the Credit
Agreement, second, to accrued but unpaid interest on the secured indebtedness,
third, to outstanding principal of the secured indebtedness, and fourth,
returned to Grantor.

     (e) RESERVE FOR INSURANCE, TAXES AND ASSESSMENTS. Upon request of Agent
while a default exists, to secure certain of Grantor's obligations in paragraphs
(c) and (d) above, but not in lieu of such obligations, Grantor will deposit
with Agent a sum equal to ad valorem taxes, assessments, and charges (which
charges for the purpose of this paragraph shall include without limitation any
recurring charge which could result in a lien against the Mortgaged Property)
against the Mortgaged Property for the current year and the premiums for such
policies of insurance for the current year, all as estimated by Agent and
prorated to the end of the calendar month following the month during which
Agent's request is made, and thereafter will deposit with Agent, on each date
when an installment of principal and/or interest is due on the Notes, sufficient
funds (as estimated from time-to-time by Agent) to permit Agent to pay at least
fifteen (15) days prior to the due date thereof, the next maturing ad valorem
taxes, assessments and charges and premiums for such policies of insurance.
Agent shall have the right to rely upon tax information furnished by applicable
taxing authorities in the payment of such taxes or assessments and shall have no
obligation to make any protest of any such taxes or assessments. Any excess over
the amounts required for such purposes shall be held by Agent for future use or
refunded to Grantor, at Agent's option, and any deficiency in such funds so
deposited shall be made up by Grantor upon demand of Agent. All such funds so
deposited shall bear no interest, may be mingled with the general funds of
Agent, and shall be applied by Agent toward the payment of such taxes,
assessments, charges, and premiums when statements therefore are presented to
Agent by Grantor (which statements shall be presented by Grantor to Agent a
reasonable time before the applicable amount is due); provided, however, that,
if a default shall have occurred hereunder, such funds may at Agent's option be
applied to the payment of the secured indebtedness in the order provided in the
Credit Agreement, and that Agent may (but shall have no obligation) at any time,
in its discretion, apply all or any part of such funds toward the payment of any
such taxes, assessments, charges,

Page 38
<PAGE>
 
or premiums which are past due, together with any penalties or late charges with
respect thereto. The conveyance or transfer of Grantor's interest in the
Mortgaged Property for any reason (including without limitation the foreclosure
of a subordinate lien or security interest or a transfer by operation of law)
shall constitute an assignment or transfer of Grantor's interest in and rights
to such funds held by Agent under this paragraph but subject to the rights of
Agent hereunder.

     (f) CONDEMNATION.  Grantor shall notify Agent immediately of any threatened
or pending proceeding for condemnation affecting the Mortgaged Property or
arising out of damage to the Mortgaged Property, and Grantor shall, at Grantor's
expense, diligently prosecute any such proceedings.  Agent shall have the right
(but not the obligation) to participate in any such proceeding and to be
represented by counsel of its own choice.  Agent shall be entitled to receive
all sums which may be awarded or become payable to Grantor for the condemnation
of the Mortgaged Property, or any part thereof, for public or quasi-public use,
or by virtue of private sale in lieu thereof, and any sums which may be awarded
or become payable to Grantor for injury or damage to the Mortgaged Property.
Grantor shall, promptly upon request of Agent, execute such additional
assignments and other documents as may be necessary from time-to-time to permit
such participation and to enable Agent to collect and receipt for any such sums.
All such sums are hereby assigned to Agent, for the benefit of Holders, and
shall, after deduction therefrom of all reasonable expenses actually incurred by
Agent, including reasonable attorneys' fees, at Agent's option be (1) released
to Grantor, or (2) applied (upon compliance with such terms and conditions as
may be required by Agent) to repair or restoration of the Mortgaged Property so
affected, or (3) applied to the payment of the secured indebtedness in such
order and manner as provided in the Credit Agreement, whether or not due. In any
event the unpaid portion of the secured indebtedness shall remain in full force
and effect and the payment thereof shall not be excused. Agent shall not be,
under any circumstances, liable or responsible for failure to collect or to
exercise diligence in the collection of any such sum or for failure to see to
the proper application of any amount paid over to Grantor. Agent is hereby
authorized, in the name of Grantor, to execute and deliver valid acquittances
for, and to appeal from, any such award, judgment, or decree. All costs and
expenses (including but not limited to attorneys' fees) incurred by Agent in
connection with any condemnation shall be a demand obligation owing by Grantor
(which Grantor hereby promises to pay) to Agent pursuant to this Deed of Trust.

     (g) COMPLIANCE WITH LEGAL REQUIREMENTS.  The Mortgaged Property and the
use, operation, and maintenance thereof and all activities thereon do and shall
at all times comply with all applicable Legal Requirements (defined below).  The
Mortgaged Property is not, and shall not be, dependent on any other property or
premises or any interest therein other than the Mortgaged Property to fulfill
any requirement of any Legal Requirement.  Grantor shall not, by act or
omission, permit any building or other improvement not subject to the lien of
this Deed of Trust to rely on the Mortgaged Property or any interest therein to
fulfill any requirement of any Legal Requirement.  No part of the Mortgaged
Property constitutes a nonconforming use under any zoning law or similar law or
ordinance.  Grantor has obtained and shall preserve in force all requisite
zoning, utility, building, health, and operating permits from the governmental
authorities having jurisdiction over the Mortgaged Property which Grantor (as
opposed to any tenant) is required to maintain.  If Grantor receives a notice or
claim from any person that the Mortgaged Property, or any use, activity,
operation, or maintenance thereof or thereon, is not in compliance with any
Legal Requirement, Grantor will promptly furnish a copy of such notice or claim
to Agent.  Grantor has received no notice and has no knowledge of any such
noncompliance.  As used in this Deed of Trust: (i) the term "LEGAL REQUIREMENT"
means any law (defined below), agreement, covenant, restriction, easement, or
condition (including, without limitation of the foregoing, any condition or
requirement imposed by any insurance or surety company), as any of the same now
exists or may be changed or amended or come into effect in the future; and (ii)
the term "LAW" means any federal, state, or local law, statute, ordinance, code,
rule, regulation, license, permit, authorization, decision, order, injunction,
or decree, domestic or foreign.

     (h)  MAINTENANCE, REPAIR AND RESTORATION.  Grantor will keep the Mortgaged
Property in good order, repair, operating condition, and appearance, causing all
necessary repairs, renewals,

Page 39
<PAGE>
 
replacements, additions and improvements to be promptly made, and will not allow
any of the Mortgaged Property to be misused, abused, or wasted or to
deteriorate, ordinary wear and tear excepted. Notwithstanding the foregoing,
Grantor will not, without the prior written consent of Agent, (i) remove from
the Mortgaged Property any fixtures or personal property covered by this Deed of
Trust except such as is replaced by Grantor by an article of equal suitability
and value, owned by Grantor, free and clear of any lien or security interest
(except that created by this Deed of Trust), or (ii) make any structural
alteration to the Mortgaged Property or any other alteration thereto which
materially and adversely impairs the value thereof. If any act or occurrence of
any kind or nature (including any condemnation or any casualty for which
insurance was not obtained or obtainable) shall result in damage to or loss or
destruction of the Mortgaged Property, Grantor shall give prompt notice thereof
to Agent and Grantor shall promptly, at Grantor's sole cost and expense and
regardless of whether insurance or condemnation proceeds (if any) shall be
available or sufficient for the purpose, commence and continue diligently to
completion to restore, repair, replace, and rebuild the Mortgaged Property as
nearly as possible to its value, condition, and character immediately prior to
the damage, loss or destruction, unless the Mortgaged Property is removed from
the Borrowing Base as provided in SECTION 2.1(D).

     (i) NO OTHER LIENS.  Except as otherwise permitted in the Credit Agreement,
Grantor will not, without the prior written consent of Agent, create, place or
permit to be created or placed, or through any act or failure to act, acquiesce
in the placing of, or allow to remain, any deed of trust, mortgage, voluntary or
involuntary lien, whether statutory, constitutional or contractual, security
interest, encumbrance or charge, or conditional sale or other title retention
document, against or covering the Mortgaged Property, or any part thereof, other
than the Permitted Encumbrances, regardless of whether the same are expressly or
otherwise subordinate to the lien or security interest created in this Deed of
Trust, and should any of the foregoing become attached hereafter in any manner
to any part of the Mortgaged Property without the prior written consent of
Agent, Grantor will cause the same to be promptly discharged and released.
Grantor will own all parts of the Mortgaged Property and will not acquire any
fixtures, equipment or other property forming a part of the Mortgaged Property
pursuant to a lease, license, security agreement, or similar agreement, whereby
any party has or may obtain the right to repossess or remove same, without the
prior written consent of Agent, except for equipment leases entered into in the
ordinary course of Grantor's business. If Agent consents to the voluntary grant
by Grantor of any lien, security interest, or other encumbrance (hereinafter
called "SUBORDINATE DEED OF TRUST") covering any of the Mortgaged Property or if
the foregoing prohibition is determined by a court of competent jurisdiction to
be unenforceable as to a Subordinate Deed of Trust, any such Subordinate Deed of
Trust shall contain express covenants to the effect that:  (1) the Subordinate
Deed of Trust is unconditionally subordinate to this Deed of Trust and all
Leases (hereinafter defined); (2) if any action (whether judicial or pursuant to
a power of sale) shall be instituted to foreclose or otherwise enforce the
Subordinate Deed of Trust, no tenant of any of the Leases (hereinafter defined)
shall be named as a party defendant, and no action shall be taken that would
terminate any occupancy or tenancy without the prior written consent of Agent;
(3) Rents (hereinafter defined), if collected by or for the holder of the
Subordinate Deed of Trust, shall be applied first to the payment of the secured
indebtedness then due and expenses incurred in the ownership, operation, and
maintenance of the Mortgaged Property in such order as provided in the Credit
Agreement, prior to being applied to any indebtedness secured by the Subordinate
Deed of Trust; (4) written notice of default under the Subordinate Deed of Trust
and written notice of the commencement of any action (whether judicial or
pursuant to a power of sale) to foreclose or otherwise enforce the Subordinate
Deed of Trust or to seek the appointment of a receiver for all or any part of
the Mortgaged Property shall be given to Agent with or immediately after the
occurrence of any such default or commencement; and (5) neither the holder of
the Subordinate Deed of Trust, nor any purchaser at foreclosure thereunder, nor
anyone claiming by, through or under any of them shall succeed to any of
Grantor's rights hereunder without the prior written consent of Agent.

     (j) OPERATION OF MORTGAGED PROPERTY. Grantor will operate the Mortgaged
Property in a good and workmanlike manner and in accordance with all Legal
Requirements and will pay all fees or charges of any kind in connection
therewith. Grantor will keep the Mortgaged Property occupied so as not

Page 40
<PAGE>
 
to impair the insurance carried thereon. Grantor will not use or occupy or
conduct any activity on, or allow the use or occupancy of or the conduct of any
activity on, the Mortgaged Property in any manner which violates any Legal
Requirement or which constitutes a public or private nuisance or which makes
void, voidable or cancelable, or increases the premium of, any insurance then in
force with respect thereto. Grantor will not initiate or permit any zoning
reclassification of the Mortgaged Property or seek any variance under existing
zoning ordinances applicable to the Mortgaged Property or use or permit the use
of the Mortgaged Property in such a manner which would result in such use
becoming a nonconforming use under applicable zoning ordinances or other Legal
Requirement. Grantor will not, without the prior written consent of Agent (such
consent of Agent not to be unreasonably withheld), impose any easement,
restrictive covenant, or encumbrance upon the Mortgaged Property, except for
easements that do not materially and adversely affect the Mortgaged Property,
execute or file any subdivision plat or condominium declaration affecting the
Mortgaged Property or consent to the annexation of the Mortgaged Property to any
municipality. Grantor will not do or suffer to be done any act whereby the value
of any part of the Mortgaged Property may be materially and adversely lessened.
Grantor will preserve, protect, renew, extend, and retain all material rights
and privileges granted for or applicable to the Mortgaged Property. Without the
prior written consent of Agent, there shall be no drilling or exploration for or
extraction, removal, or production of any mineral, hydrocarbon, gas, natural
element, compound, or substance (including sand and gravel) from the surface or
subsurface of the Land regardless of the depth thereof or the method of mining
or extraction thereof. Grantor will cause all debts and liabilities of any
character (including without limitation all debts and liabilities for labor,
material and equipment and all debts and charges for utilities servicing the
Mortgaged Property) incurred in the construction, maintenance, operation, and
development of the Mortgaged Property to be promptly paid, except for debts and
liabilities being contested in good faith by appropriate proceedings and for
which Grantor has established reserves in accordance with GAAP or obtained other
security (in each case reasonably acceptable to the Administrative Agent).

     (k) CERTAIN ENVIRONMENTAL MATTERS.

          (i) DEFINITIONS.  As used in this Deed of Trust: (1) "ENVIRONMENTAL
CLAIM" means any investigative, enforcement, cleanup, removal, containment,
remedial, or other governmental or regulatory action at any time threatened,

          (ii) REPRESENTATIONS AND WARRANTIES. Grantor represents and warrants
to Agent and Holders, without regard to whether Agent or any Holder has or
hereafter obtains any knowledge or report of the environmental condition of the
Mortgaged Property, that (except as specifically disclosed to

Page 41
<PAGE>
 
Agent in a written environmental report or other writing delivered by Grantor to
Agent prior to the date of execution hereof): (1) during the period of Grantor's
ownership of the Mortgaged Property, the Mortgaged Property has not been used
for industrial or manufacturing purposes, for landfill, dumping or other waste
disposal activity or operation, for generation, storage, use, sale, treatment,
processing, recycling, or disposal of any Hazardous Substance, or for any other
use that would give rise to the release of any Hazardous Substance on the
Mortgaged Property except for (A) the storage and use of cleaning and
maintenance materials, used and stored in commercially reasonable quantities and
in compliance with applicable Environmental Requirements, and (B) light
manufacturing and distribution activities of tenants, in compliance with
applicable Environmental Requirements, provided that such tenants are not
primarily engaged in the treatment, processing, recycling, or disposal of any
Hazardous Substance, or for any other use that would give rise to the release of
any Hazardous Substance on the Mortgaged Property; (2) to the best of Grantor's
knowledge after inquiry in accordance with good commercial or customary
practices, no use of the Mortgaged Property described in clause (1) preceding
occurred at any time prior to the period of Grantor's ownership of the Mortgaged
Property nor did any such use on any adjacent property occur during or at any
time prior to the period of Grantor's ownership of the Mortgaged Property, and
there is no Hazardous Substance, storage tanks (or similar vessel), sump or well
on the Mortgaged Property; (3) Grantor has received no notice and has no
knowledge of any Environmental Claim or any completed, pending, proposed or
threatened investigation or inquiry concerning the presence or release of any
Hazardous Substance on the Mortgaged Property or on any adjacent property or
concerning whether any condition, use or activity on the Mortgaged Property or
on any adjacent property is in violation of any Environmental Requirement; (4)
the present conditions, uses, and activities on the Mortgaged Property do not
violate any Environmental Requirement and the use of the Mortgaged Property
which Grantor (and each tenant and subtenant, if any) makes and intends to make
of the Mortgaged Property complies and will comply with all applicable
Environmental Requirements; (5) the Mortgaged Property is not currently on, and
to the best of Grantor's knowledge after inquiry in accordance with good
commercial or customary practices, has never been on, any federal or state
"superfund" or "superlien" list; and (6) neither Grantor, nor to Grantor's
knowledge any tenant or subtenant, has obtained or is required to obtain any
permit or other authorization to construct, occupy, operate, use, or conduct any
activity on any of the Mortgaged Property by reason of any Environmental
Requirement.

          (iii)  VIOLATIONS.  Grantor will not cause, commit, permit or allow to
continue any violation of any Environmental Requirement by Grantor or by or with
respect to the Mortgaged Property or any use or activity on the Mortgaged
Property, or the attachment of any environmental lien to the Mortgaged Property.
Grantor will not place, install, dispose of, or release, or cause, permit or
allow the placing, installation, disposal or release of, any Hazardous Substance
or storage tank (or similar vessel) on the Mortgaged Property and will keep the
Mortgaged Property free of any Hazardous Substance, if the failure to do any of
the foregoing would subject the Mortgaged Property to remediation or reporting
requirements under any Environmental Requirement, except for (A) the storage and
use of cleaning and maintenance materials, used and stored in commercially
reasonable quantities in compliance with applicable Environmental Requirements,
and (B) light manufacturing and distribution activities of tenants, in
compliance with applicable Environmental Requirements, provided that such
tenants are not primarily engaged in the treatment, processing, recycling, or
disposal of any Hazardous Substance.

          (iv)   NOTICE TO AGENT.  Grantor will promptly advise Agent in writing
of any Environmental Claim or of the discovery of any Hazardous Substance on the
Mortgaged Property, as soon as Grantor first obtains knowledge thereof,
including a full description of the nature and extent of the Environmental Claim
and/or Hazardous Substance and all relevant circumstances.

          (v)    SITE ASSESSMENTS AND INFORMATION. If Agent shall ever have
reason to believe that any Hazardous Substance affects the Mortgaged Property,
or if any Environmental Claim is made or threatened, or if a default shall have
occurred, Grantor will at its expense provide to Agent from time-to-time, in
each case within thirty (30) days of Agent's request, a report (including all
drafts thereof if

Page 42
<PAGE>
 
requested by Agent) of an environmental assessment of the Mortgaged Property
made after the date of Agent's request and of such scope (including but not
limited to the taking of soil borings, air and groundwater samples and other
above and below ground testing) as Agent may request and by a consulting firm
acceptable to Agent. Grantor will cooperate with each consulting firm making any
such assessment and will supply to the consulting firm, from time-to-time and
promptly on request, all information available to Grantor to facilitate the
completion of the assessment and report.

          (vi) REMEDIAL ACTIONS.  Without limitation of Agent's rights to
declare a default and to exercise all remedies available by reason thereof, if
any Hazardous Substance is discovered on the Mortgaged Property at any time and
regardless of the cause, Grantor shall: (1) promptly at Grantor's sole risk and
expense remove, treat, and dispose of the Hazardous Substance in compliance with
all applicable Environmental Requirements and solely under Grantor's name (or if
removal is prohibited by any Environmental Requirement, take whatever action is
required by applicable Environmental Requirements), in addition to taking such
other action as is necessary to have the full use and benefit of the Mortgaged
Property as contemplated by the Loan Documents, and provide Agent with
satisfactory evidence thereof; and (2) if requested by Agent, provide to Agent
within thirty (30) days of Agent's request a bond, letter of credit, or other
financial assurance evidencing to Agent's satisfaction that all necessary funds
are readily available to pay the costs and expenses of the actions required by
clause (1) preceding and to discharge any assessments or liens established
against the Mortgaged Property as a result of the presence of the Hazardous
Substance on the Mortgaged Property.

     (l) FURTHER ASSURANCES.  Grantor will, promptly on request of Agent:  (i)
correct any defect, error, or omission which may be discovered in the contents,
execution, or acknowledgment of this Deed of Trust or any other Loan Document;
(ii) execute, acknowledge, deliver, procure, and record and/or file such further
documents (including, without limitation, further deeds of trust, security
agreements, financing statements, continuation statements, and assignments of
rents or leases) and do such further acts as may be reasonably necessary,
desirable, or proper to carry out more effectively the purposes of this Deed of
Trust and the other Loan Documents, to more fully identify and subject to the
liens and security interests hereof any property intended to be covered hereby
(including specifically, but without limitation, any renewals, additions,
substitutions, replacements, or appurtenances to the Mortgaged Property) or as
deemed advisable by Agent to protect the lien or the security interest hereunder
against the rights or interests of third persons; and (iii) provide such
certificates, documents, reports, information, affidavits, and other instruments
and do such further acts as may be reasonably necessary, desirable, or proper in
the reasonable determination of Agent to enable Agent to comply with the
requirements or requests of any agency having jurisdiction over Agent or any
examiners of such agencies with respect to the indebtedness secured hereby,
Grantor or the Mortgaged Property.  Grantor shall pay all costs connected with
any of the foregoing, which shall be a demand obligation owing by Grantor (which
Grantor hereby promises to pay) to Agent pursuant to this Deed of Trust.

     (m) FEES AND EXPENSES.  Without limitation of any other provision of this
Deed of Trust or of any other Loan Document and to the extent not prohibited by
applicable law, Grantor will pay, and will reimburse to Agent and/or Trustee on
demand to the extent paid by Agent and/or Trustee all costs and expenses,
including reasonable attorneys' fees and expenses, incurred or expended in
connection with the exercise of any right or remedy, or the enforcement of any
obligation of Grantor, hereunder.

     (n) INDEMNIFICATION.

         (i) Grantor will indemnify and hold harmless Agent, Holders, and
Trustee from and against, and reimburse them on demand for, any and all
Indemnified Matters (defined below).  For purposes of this paragraph (p), the
terms "Agent," "Holder," and "Trustee" shall include the directors, officers,
partners, employees, and agents of Agent, each Holder, and Trustee,
respectively, and any persons 

Page 43
<PAGE>
 
owned or controlled by, owning or controlling, or under common control or
affiliated with any Agent, Holder, or Trustee, respectively. WITHOUT LIMITATION,
THE FOREGOING INDEMNITIES SHALL APPLY TO EACH INDEMNIFIED PERSON WITH RESPECT TO
MATTERS WHICH IN WHOLE OR IN PART ARE CAUSED BY OR ARISE OUT OF THE NEGLIGENCE
OF SUCH (AND/OR ANY OTHER) INDEMNIFIED PERSON. However, such indemnities shall
not apply to a particular indemnified person to the extent that the subject of
the indemnification is caused by or arises out of the gross negligence or
willful misconduct of that indemnified person. Any amount to be paid under this
PARAGRAPH (N) by Grantor to Agent, any Holder, and/or Trustee shall be a demand
obligation owing by Grantor (which Grantor hereby promises to pay) to Agent, any
Holder, and/or Trustee pursuant to this Deed of Trust. Nothing in this
paragraph, elsewhere in this Deed of Trust or in any other Loan Document shall
limit or impair any rights or remedies of Agent, any Holder, and/or Trustee
(including without limitation any rights of contribution or indemnification)
against Grantor or any other person under any other provision of this Deed of
Trust, any other Loan Document, any other agreement or any applicable Legal
Requirement.

          (ii) As used herein, the term "INDEMNIFIED MATTERS" means any and all
claims, demands, liabilities (including strict liability), losses, damages
(including consequential damages), causes of action, judgments, penalties,
costs, and expenses (including without limitation, reasonable fees and expenses
of attorneys and other professional consultants and experts, and of the
investigation and defense of any claim, whether or not such claim is ultimately
defeated, and the settlement of any claim or judgment including all value paid
or given in settlement) of every kind, known or unknown, foreseeable or
unforeseeable, which may be imposed upon, asserted against or incurred or paid
by, Agent, any Holder, and/or Trustee at any time and from time-to-time,
whenever imposed, asserted or incurred, because of, resulting from, in
connection with, or arising out of any transaction, act, omission, event or
circumstance in any way connected with the Mortgaged Property or with this Deed
of Trust or any other Loan Document, including but not limited to any bodily
injury or death or property damage occurring in or upon or in the vicinity of
the Mortgaged Property through any cause whatsoever at any time on or before the
Release Date, any act performed or omitted to be performed hereunder or under
any other Loan Document on or before the Release Date, any breach by Grantor of
any representation, warranty, covenant, agreement, or condition contained in
this Deed of Trust or in any other Loan Document, any default as defined herein,
any claim under or with respect to any Lease (hereinafter defined) and any
Environmental Matter (defined below) on or before the Release Date. As used
herein, the term "ENVIRONMENTAL MATTER" means: (a) the presence of any Hazardous
Substance on, in, under, above, or about the Mortgaged Property, or the
migration or release or threatened migration or release of any Hazardous
Substance on, to, from, or through the Mortgaged Property, on or at any time
before the Release Date; or (b) any act, omission, event, or circumstance
existing or occurring in connection with the handling, treatment, containment,
removal, storage, decontamination, clean-up, transport, or disposal of any
Hazardous Substance which is at any time on or before the Release Date present
on, in, under, above or about the Mortgaged Property; or (c) any violation on or
before the Release Date, of any Environmental Requirement in effect on or before
the Release Date, regardless of whether any act, omission, event or circumstance
giving rise to the violation constituted a violation at the time of the
occurrence or inception of such act, omission, event or circumstance; or (d) any
Environmental Claim, or the filing or imposition of any environmental lien
against the Mortgaged Property, because of, resulting from, in connection with,
or arising out of any of the matters referred to in clauses (a) through (c)
preceding; and regardless of whether any of the matters referred to in the
foregoing clauses (a) through (d) was caused by Grantor or Grantor's tenant or
any subtenant, or a prior owner of the Mortgaged Property or its tenant or any
subtenant, or any third party. Without limitation of the definition of
Indemnified Matters herein, Grantor's indemnification obligations regarding any
Environmental Matter shall include injury or damage to any person, property or
natural resource occurring upon or off of the Mortgaged Property (including but
not limited to the cost of demolition and rebuilding of any improvements on real
property), the preparation of any feasibility studies or reports and the
performance of any cleanup, remediation, removal, response, abatement,
containment, closure, restoration, monitoring, or similar work required by any
Environmental Requirement or necessary to have the full use and benefit of the
Mortgaged Property as contemplated by the Loan Documents (including, without

Page 44
<PAGE>
 
limitation, any of the same in connection with any foreclosure, or transfer in
lieu thereof), and all liability to pay or indemnify any person for costs in
connection with any of the foregoing. The term "RELEASE DATE" as used herein
means the earlier of the following two dates: (i) the date on which the
indebtedness and obligations secured hereby have been paid and performed in full
and this Deed of Trust has been released, or (ii) the date on which the lien of
this Deed of Trust is fully and finally foreclosed or a conveyance by deed in
lieu of such foreclosure is fully and finally effective, and possession of the
Mortgaged Property has been given to the purchaser or grantee free of occupancy
and claims to occupancy by Grantor and Grantor's heirs, devisees,
representatives, successors, and assigns; provided, that if such payment,
performance, release, foreclosure, or conveyance is challenged, in bankruptcy
proceedings or otherwise, the Release Date shall be deemed not to have occurred
until such challenge is rejected, dismissed, or withdrawn with prejudice. The
indemnities in this PARAGRAPH (N) shall not terminate upon the Release Date or
upon the release, foreclosure or other termination of this Deed of Trust but
will survive the Release Date, foreclosure of this Deed of Trust or conveyance
in lieu of foreclosure, the repayment of the secured indebtedness, the discharge
and release of this Deed of Trust and the other Loan Documents, any bankruptcy
or other debtor relief proceeding, and any other event whatsoever.

     (o) RECORDS AND FINANCIAL REPORTS.  Grantor will keep accurate books and
records in accordance with sound accounting principles in which full, true and
correct entries shall be promptly made with respect to the Mortgaged Property
and the operation thereof, and upon reasonable notice will permit all such books
and records to be inspected and copied, and, subject to rights of tenants, the
Mortgaged Property to be inspected and photographed, by Agent and its
representatives upon reasonable notice and during normal business hours and at
any other reasonable times.  Without limitation of other or additional
requirements in any of the other Loan Documents, Grantor will furnish to Agent
current operating statements itemizing all income and expenses of the Mortgaged
Property, for each month (and for the fiscal year through the end of such month)
as soon as reasonably practicable but in any event within thirty (30) days after
the end of such month and for each fiscal year of Grantor within ninety (90)
days after the end thereof including also a projection of such operations for
the next fiscal year.  Each financial statement submitted pursuant to this
paragraph shall be certified in writing as true and correct by Grantor (or if
Grantor is not a natural person, by a representative of Grantor acceptable to
Agent).  Grantor will furnish to Agent at Grantor's expense all evidence which
Agent may from time-to-time reasonably request as to compliance with all
provisions of the Loan Documents.  Any inspection or audit of the Mortgaged
Property or the books and records of Grantor, or the procuring of documents and
financial and other information, by or on behalf of Agent shall be for Agent's
protection only, and shall not constitute any assumption of responsibility to
Grantor or anyone else with regard to the condition, construction, maintenance,
or operation of the Mortgaged Property nor Agent's approval of any certification
given to Agent nor relieve Grantor of any of Grantor's obligations.  Grantor
consents to the delivery by Agent to any acquirer or prospective acquirer of any
interest or participation in or with respect to all or part of the secured
indebtedness such information as Agent now or hereafter has relating to the
Mortgaged Property, Grantor, any party obligated for payment of any part of the
secured indebtedness, any tenant or guarantor under any lease affecting any part
of the Mortgaged Property and any agent or guarantor under any management
agreement affecting any part of the Mortgaged Property.
 
     (p) TAXES ON NOTES OR DEED OF TRUST. Grantor will promptly pay all income,
franchise, and other taxes owing by Grantor and any stamp taxes or other taxes
(unless such payment by Grantor is prohibited by law) which may be required to
be paid with respect to the Credit Agreement, the Notes, this Deed of Trust, or
any other instrument evidencing or securing any of the secured indebtedness. In
the event of the enactment after this date of any law of any governmental entity
applicable to Agent, Holders, the Credit Agreement, the Notes, the Mortgaged
Property, or this Deed of Trust deducting from the value of property for the
purpose of taxation any lien or security interest thereon, or imposing upon
Agent the payment of the whole or any part of the taxes or assessments or
charges or liens herein required to be paid by Grantor, or changing in any way
the laws relating to the taxation of deeds of trust or mortgages or security
agreements or debts secured by deeds of trust or mortgages or security
agreements or the interest

Page 45
<PAGE>
 
of the mortgagee or secured party in the property covered thereby, or the manner
of collection of such taxes, so as to affect this Deed of Trust or the
indebtedness secured hereby or Agent, then, and in any such event, Grantor, upon
demand by Agent, shall pay such taxes, assessments, charges or liens, or
reimburse Agent therefor; provided, however, that if in the opinion of counsel
for Agent (i) it might be unlawful to require Grantor to make such payment or
(ii) the making of such payment might result in the imposition of interest
beyond the maximum amount permitted by law, then and in such event, then Agent,
at the direction of the Required Lenders (as defined in the Credit Agreement),
may elect, by notice in writing given to Grantor, to declare all of the
indebtedness secured hereby to be and become due and payable sixty (60) days
from the giving of such notice.

     (q) STATEMENT CONCERNING NOTES OR DEED OF TRUST.  Grantor shall at any time
and from time-to-time furnish within seven (7) days of request by Agent a
written statement in such form as may be required by Agent stating that (i) the
Credit Agreement  the Notes, this Deed of Trust, and the other Loan Documents
are valid and binding obligations of Grantor, enforceable against Grantor in
accordance with their terms subject to general principles of equity and
applicable debtor relief laws affecting the rights of creditors generally; (ii)
the unpaid principal balance of the Notes; (iii) the date to which interest on
the Notes is paid; (iv)  the Credit Agreement, the Notes, this Deed of Trust and
the other Loan Documents have not been released, subordinated or modified; and
(v) there are no offsets or defenses against the enforcement of the Credit
Agreement, the Notes, this Deed of Trust, or any other Loan Document.  If any of
the foregoing statements are untrue, Grantor shall, alternatively, specify the
reasons therefor.

     Section 2.2.  PERFORMANCE BY AGENT ON GRANTOR'S BEHALF.  Grantor agrees
that, if Grantor fails to perform any act or to take any action which under any
Loan Document Grantor is required to perform or take, or to pay any money which
under any Loan Document Grantor is required to pay, and whether or not the
failure then constitutes a default hereunder or thereunder, and whether or not
there has occurred any default or defaults hereunder or the secured indebtedness
has been accelerated, Agent, in Grantor's name or its own name, may, but shall
not be obligated to, perform or cause to be performed such act or take such
action or pay such money, and any expenses so incurred by Agent and any money so
paid by Agent shall be  payable promptly following demand (which obligation
Grantor hereby promises to pay), shall be a part of the indebtedness secured
hereby, and Agent, upon making such payment, shall be subrogated to all of the
rights of the person, entity, or body politic receiving such payment.  Upon
reasonable notice and subject to the rights of tenants, Agent and its designees
shall have the right to enter upon the Mortgaged Property at any time and from
time-to-time for any such purposes.  No such payment or performance by Agent
shall waive or cure any default or waive any right, remedy or recourse of Agent
or any Holder.  Any such payment may be made by Agent in reliance on any
statement, invoice or claim without inquiry into the validity or accuracy
thereof.  Each amount due and owing by Grantor to Agent or any Holder pursuant
to this Deed of Trust shall bear interest, from the date such amount becomes due
until paid, at the rate per annum provided in the Credit Agreement for interest
on past-due principal owed on the Notes but never in excess of the maximum
nonusurious amount permitted by applicable law, which interest shall be payable
to Agent and to Holders  promptly following demand; and all such amounts,
together with such interest thereon, shall automatically and without notice be a
part of the indebtedness secured hereby.  The amount and nature of any expense
by Agent hereunder and the time when paid shall be fully established by the
certificate of Agent or any of Agent's officers or agents.  Agent shall exercise
its reasonable best efforts to notify Grantor prior to taking any such steps or
incurring any such expenditures, except in the case of exigent circumstances.

     Section 2.3.  ABSENCE OF OBLIGATIONS OF AGENT OR HOLDERS WITH RESPECT TO
MORTGAGED PROPERTY.  Notwithstanding anything in this Deed of Trust to the
contrary, including, without limitation, the definition of "Mortgaged Property"
and/or the provisions of ARTICLE 3 hereof, (i) to the extent permitted by
applicable law, the Mortgaged Property is composed of Grantor's rights, titles
and interests therein but not Grantor's obligations, duties, or liabilities
pertaining thereto, (ii) neither Agent nor any Holder assumes nor shall have any
obligations, duties, or liabilities in connection with any portion of the items
described in the 

Page 46
<PAGE>
 
definition of "Mortgaged Property" herein, either prior to or after obtaining
title to such Mortgaged Property, whether by foreclosure sale, the granting of a
deed in lieu of foreclosure or otherwise, and (iii) Agent may, at any time prior
to or after the acquisition of title to any portion of the Mortgaged Property as
above described, advise any party in writing as to the extent of Agent's
interest therein and/or expressly disaffirm in writing any rights, interests,
obligations, duties, and/or liabilities with respect to such Mortgaged Property
or matters related thereto. Without limiting the generality of the foregoing, it
is understood and agreed that neither Agent nor any Holder shall have any
obligations, duties, or liabilities prior to or after acquisition of title to
any portion of the Mortgaged Property, as lessee under any lease or purchaser or
seller under any contract or option unless Agent or such Holder elects otherwise
by written notification.

                                   ARTICLE 3

                   COLLATERAL ASSIGNMENT OF RENTS AND LEASES

     Section 3.1.  ASSIGNMENT.  As additional security for the indebtedness
secured hereby, Grantor hereby assigns to Agent, for the benefit of Holders, all
Rents (hereinafter defined) and all of Grantor's rights in and under all Leases
(hereinafter defined).  Upon the occurrence of a default hereunder, Agent shall
have the right, power, and privilege (but shall be under no duty) to demand
possession of the Rents, which demand shall to the fullest extent permitted by
applicable law be sufficient action by Agent to entitle Agent to immediate and
direct payment of the Rents, (including delivery to Agent of Rents collected for
the period in which the demand occurs and for any subsequent period), for
application as provided in this Deed of Trust, all without the necessity of any
further action by Agent, including, without limitation, any action to obtain
possession of the Land, Improvements or any other portion of the Mortgaged
Property.  Grantor hereby authorizes and directs the tenants under the Leases to
pay Rents to Agent upon written demand by Agent, without further consent of
Grantor, without any obligation to determine whether a default has in fact
occurred and regardless of whether Agent has taken possession of any portion of
the Mortgaged Property, and the tenants may rely upon any written statement
delivered by Agent to the tenants. Any such payment to Agent shall constitute
payment to Grantor under the Leases, and Grantor hereby appoints Agent as
Grantor's lawful attorney-in-fact for giving, and Agent is hereby empowered to
give, acquittances to any tenants for such payments to Agent after a default.
The assignment contained in this SECTION shall become null and void upon the
release of this Deed of Trust. As used herein: (i) "LEASE" means each existing
or future lease, sublease (to the extent of Grantor's rights thereunder) or
other agreement under the terms of which any person has or acquires any right to
occupy or use the Mortgaged Property, or any part thereof, or interest therein,
and each existing or future guaranty of payment or performance thereunder, and
all extensions, renewals, modifications and replacements of each such lease,
sublease, agreement or guaranty; and (ii) "RENTS" means all of the rents,
revenue, income, profits and proceeds derived and to be derived from the
Mortgaged Property or arising from the use or enjoyment of any portion thereof
or from any Lease, including but not limited to liquidated damages following
default under any such Lease, all proceeds payable under any policy of insurance
covering loss of rents resulting from untenantability caused by damage to any
part of the Mortgaged Property, all of Grantor's rights to recover monetary
amounts from any tenant in bankruptcy including, without limitation, rights of
recovery for use and occupancy and damage claims arising out of Lease defaults,
including rejections, under any applicable Debtor Relief Law (as hereinafter
defined), together with any sums of money that may now or at any time hereafter
be or become due and payable to Grantor by virtue of any and all royalties,
overriding royalties, bonuses, delay rentals and any other amount of any kind or
character arising under any and all present and all future oil, gas, mineral and
mining leases covering the Mortgaged Property or any part thereof, and all
proceeds and other amounts paid or owing to Grantor under or pursuant to any and
all contracts and bonds relating to the construction or renovation of the
Mortgaged Property.

AND RENTS.

grant any rent-free period to any tenant, reduce any Lease term or waive,
release, or otherwise modify any other material obligation under any Lease,
approve or consent to an assignment of a Lease or a subletting of any part of
the premises covered by a Lease, or settle or compromise any claim against a
tenant under a Lease in bankruptcy or otherwise; (viii) Grantor will not, except
in good faith where the tenant is in material default thereunder or in the
ordinary course of Borrower's business so long as no default exists, terminate
or consent to the cancellation or surrender of any Lease having an unexpired

defend, at Grantor's expense, any proceeding pertaining to any Lease, including,
if Agent so requests, any such proceeding to which Agent is a party; (xi)
Grantor shall as often as requested by Agent (but not more often than once each
calendar month), within ten (10) days of each request, deliver to Agent a
complete rent roll of the Mortgaged Property in such detail as Agent may
reasonably require, and financial statements of the tenants, subtenants and
guarantors under the Leases to the extent available to Grantor, and deliver to
such of the tenants and others obligated under the Leases specified by Agent
written notice of the assignment in SECTION 3.1 hereof in form and content
satisfactory to Agent; (xii) promptly upon request by Agent, Grantor shall
deliver to Agent executed originals of all Leases and copies of all records
relating thereto; (xiii) there shall be no merger of the leasehold estates,
created by the Leases, with the fee estate of the Land without the prior written
consent of Agent; and (xiv) Agent may at any time and from time-to-time by
specific written instrument intended for the purpose, unilaterally subordinate
the lien of this Deed of Trust to any Lease, without joinder or consent of, or
notice to, Grantor, any tenant or any other person, and notice is hereby given
to each tenant under a Lease of such right to subordinate; and (xv) the Leases
and all of each lessee's rights thereunder are, shall be, and shall remain
subordinate and inferior to this Deed of Trust, the other Loan Documents, and
the liens and security interests created hereby and thereby.  No such
subordination shall constitute a subordination to any lien or other encumbrance,
whenever arising, or improve the right of any junior lienholder; and nothing
herein shall be construed as subordinating this Deed of Trust to any Lease.

     Section 3.3.  NO LIABILITY OF AGENT OR HOLDER.  Agent's acceptance of this
assignment shall not be deemed to constitute Agent a "mortgagee in possession,"
nor obligate Agent to appear in or defend any proceeding relating to any Lease
or to the Mortgaged Property, or to take any action hereunder, expend any money,
incur any expenses, or perform any obligation or liability under any Lease, or
assume any obligation for any deposit delivered to Grantor by any tenant and not
as such delivered to and accepted by Agent.  Neither Agent nor any Holder shall
be liable for any injury or damage to person or property in or about the
Mortgaged Property, or for Agent's failure to collect or to exercise diligence
in collecting Rents, 

Page 48
<PAGE>
 
but shall be accountable only for Rents that it shall actually receive. Neither
the assignment of Leases and Rents nor enforcement of Agent's rights regarding
Leases and Rents (including collection of Rents) nor possession of the Mortgaged
Property by Agent nor Agent's consent to or approval of any Lease (nor all of
the same), shall render Agent liable on any obligation under or with respect to
any Lease or constitute affirmation of, or any subordination to, any Lease,
occupancy, use or option. If Agent seeks or obtains any judicial relief
regarding Rents or Leases, the same shall in no way prevent the concurrent or
subsequent employment of any other appropriate rights or remedies nor shall same
constitute an election of judicial relief for any foreclosure or any other
purpose. Agent neither has nor assumes any obligations as lessor or landlord
with respect to any Lease. The rights of Agent under this ARTICLE 3 shall be
cumulative of all other rights of Agent under the Loan Documents or otherwise.

                                 ARTICLE 4

                                 DEFAULT

     Section 4.1.  EVENTS OF DEFAULT.  The occurrence of any one of the
following shall be a default under this Deed of Trust ("DEFAULT"):

     (a) CREDIT AGREEMENT.  A Default under the Credit Agreement.

     (b) TRANSFER OF THE MORTGAGED PROPERTY.  Except as otherwise permitted in
the Loan Documents, any sale, lease, conveyance, assignment, pledge,
encumbrance, or transfer of all or any part of the Mortgaged Property or any
interest therein, voluntarily or involuntarily, whether by operation of law or
otherwise, except:  (i) sales or transfers of items of the Accessories which
have become obsolete or worn beyond practical use and which have been replaced
by adequate substitutes, owned by Grantor, having a value equal to or greater
than the replaced items when new; and (ii) the grant, in the ordinary course of
business, of a leasehold interest in a part of the Improvements to a tenant for
occupancy, not containing a right or option to purchase and not in contravention
of any provision of this Deed of Trust or of any other Loan Document.  Agent
may, in its sole discretion, waive a default under this paragraph, but it shall
have no obligation to do so, and any waiver may be conditioned upon such one or
more of the following (if any) which Agent may require:  the grantee's
integrity, reputation, character, creditworthiness and management ability being
satisfactory to Agent in its sole judgment and grantee executing, prior to such
sale or transfer, a written assumption agreement containing such terms as Agent
may require, a principal paydown on the Note, an increase in the rate of
interest payable under the Note, a transfer fee, a modification of the term of
the Note, and any other modification of the Loan Documents which Agent may
require.

     (c) ABANDONMENT.  The owner of the Mortgaged Property abandons any of the
Mortgaged Property.

     (d) DEFAULT UNDER OTHER LIEN.  A default or event of default occurs under
any lien, security interest, or assignment covering the Mortgaged Property or
any part thereof (whether or not Agent has consented, and without hereby
implying Agent's consent, to any such lien, security interest, or assignment not
created hereunder), or the holder of any such lien, security interest, or
assignment declares a default or institutes foreclosure or other proceedings for
the enforcement of its remedies thereunder.

     (e) ENFORCEABILITY; PRIORITY.  The liens, mortgages, or security interests
of Agent in any of the Mortgaged Property, for the benefit of Lenders, become
unenforceable in whole or in part, or cease to be of the priority herein
required, or the validity or enforceability thereof, in whole or in part, shall
be challenged or denied by Grantor or any person obligated to pay any part of
the secured indebtedness, unless the Mortgaged Property is removed from the
Borrowing Base and, after giving effect thereto, no default exists 

Page 49
<PAGE>
 
and the remaining Borrowing Base exceeds the Obligation.

     (f) OTHER LOAN DOCUMENTS.  A default or event of default occurs under any
Loan Document, other than this Deed of Trust, and the same is not remedied
within the applicable period of grace (if any) provided in such Loan Document.

     Section 4.2 NOTICE AND CURE. If any provision of this Deed of Trust or any
other Loan Document provides for Agent to give to Grantor any notice regarding a
default or incipient default, then if Agent shall fail to give such notice to
Grantor as provided, the sole and exclusive remedy of Grantor for such failure
shall be to seek appropriate equitable relief to enforce the agreement to give
such notice and to have any acceleration of the maturity of the Notes and the
secured indebtedness postponed or revoked and foreclosure proceedings in
connection therewith delayed or terminated pending or upon the curing of such
default in the manner and during the period of time permitted by such agreement,
if any, and Grantor shall have no right to damages or any other type of relief
not herein specifically set out against Agent, all of which damages or other
relief are hereby waived by Grantor. Nothing herein or in any other Loan
Document shall operate or be construed to add on or make cumulative any cure or
grace periods specified in any of the Loan Documents.

                                 ARTICLE 5

                                 REMEDIES

     Section 5.1.  CERTAIN REMEDIES.  If a default shall occur and be
continuing, Agent may (but shall have no obligation to) exercise any one or more
of the following remedies, without notice (unless notice is required by
applicable statute):

     (a) ACCELERATION.  Agent may at any time and from time-to-time declare any
or all of the secured indebtedness immediately due and payable and such secured
indebtedness shall thereupon be immediately due and payable, without
presentment, demand, protest, notice of protest, notice of acceleration or of
intention to accelerate or any other notice or declaration of any kind, all of
which are hereby expressly waived by Grantor.  Without limitation of the
foregoing, upon the occurrence of a default described in Section 10.3 of the
Credit Agreement, all of the secured indebtedness shall thereupon be immediately
due and payable, without presentment, demand, protest, notice of protest,
declaration or notice of acceleration or intention to accelerate, or any other
notice, declaration, or act of any kind, all of which are hereby expressly
waived by Grantor.

     (b) ENFORCEMENT OF ASSIGNMENT OF RENTS.  Prior or subsequent to taking
possession of any portion of the Mortgaged Property or taking any action with
respect to such possession, Agent may:  (1) collect and/or sue for the Rents in
Agent's own name, give receipts and releases therefor, and after deducting all
expenses of collection, including reasonable attorneys' fees and expenses, apply
the net proceeds thereof to the secured indebtedness in such manner and order as
Agent may elect and/or to the operation and management of the Mortgaged
Property, including the payment of management, brokerage, and reasonable
attorneys' fees and expenses; and (2) require Grantor to transfer all security
deposits and records thereof to Agent together with original counterparts of the
Leases.

     (c) FORECLOSURE. Upon the occurrence of a default, Trustee, or his
successor or substitute, is authorized and empowered and it shall be his special
duty at the request of Agent to sell the Mortgaged Property or any part thereof
situated in the State of Texas, at the courthouse of any county (whether or not
the counties in which the Mortgaged Property is located are contiguous, if the
Mortgaged Property is located in more than one county) in the State of Texas in
which any part of the Mortgaged Property is

Page 50
<PAGE>
 
situated, at public vendue to the highest bidder for cash between the hours of
ten o'clock a.m. and four o'clock p.m. on the first Tuesday in any month or at
such other place, time and date as provided by the statutes of the State of
Texas then in force governing sales of real estate under powers of sale
conferred by deed of trust, after having given notice of such sale in accordance
with such statutes. Any sale made by Trustee hereunder may be as an entirety or
in such parcels as Agent may request. To the extent permitted by applicable law,
any sale may be adjourned by announcement at the time and place appointed for
such sale without further notice except as may be required by law. The sale by
Trustee of less than the whole of the Mortgaged Property shall not exhaust the
power of sale herein granted, and Trustee is specifically empowered to make
successive sale or sales under such power until the whole of the Mortgaged
Property shall be sold; and, if the proceeds of such sale of less than the whole
of the Mortgaged Property shall be less than the aggregate of the indebtedness
secured hereby and the expense of executing this trust as provided herein, this
Deed of Trust and the lien hereof shall remain in full force and effect as to
the unsold portion of the Mortgaged Property just as though no sale had been
made; provided, however, that Grantor shall never have any right to require the
sale of less than the whole of the Mortgaged Property but Agent shall have the
right, at its sole election, to request Trustee to sell less than the whole of
the Mortgaged Property. Trustee may, after any request or direction by Agent,
sell not only the real property but also the Collateral and other interests
which are a part of the Mortgaged Property, or any part thereof, as a unit and
as a part of a single sale, or may sell any part of the Mortgaged Property
separately from the remainder of the Mortgaged Property. It shall not be
necessary for Trustee to have taken possession of any part of the Mortgaged
Property or to have present or to exhibit at any sale any of the Collateral.
After each sale, Trustee shall make to the purchaser or purchasers at such sale
good and sufficient conveyances in the name of Grantor, conveying the property
so sold to the purchaser or purchasers with general warranty of title by
Grantor, subject to the Permitted Encumbrances (and to such leases and other
matters, if any, as Trustee may elect upon request of Agent), and shall receive
the proceeds of said sale or sales and apply the same as herein provided.
Payment of the purchase price to the Trustee shall satisfy the obligation of
purchaser at such sale therefor, and such purchaser shall not be responsible for
the application thereof. The power of sale granted herein shall not be exhausted
by any sale held hereunder by Trustee or his substitute or successor, and such
power of sale may be exercised from time-to-time and as many times as Agent may
deem necessary until all of the Mortgaged Property has been duly sold and all
secured indebtedness has been fully paid. In the event any sale hereunder is not
completed or is defective in the opinion of Agent, such sale shall not exhaust
the power of sale hereunder and Agent shall have the right to cause a subsequent
sale or sales to be made hereunder. Any and all statements of fact or other
recitals made in any deed or deeds or other conveyances given by Trustee or any
successor or substitute appointed hereunder as to nonpayment of the secured
indebtedness or as to the occurrence of any default, or as to Agent's having
declared all of said indebtedness to be due and payable, or as to the request to
sell, or as to notice of time, place and terms of sale and the properties to be
sold having been duly given, or as to the refusal, failure or inability to act
of Trustee or any substitute or successor trustee, or as to the appointment of
any substitute or successor trustee, or as to any other act or thing having been
duly done by Agent or by such Trustee, substitute or successor, shall be taken
as prima facie evidence of the truth of the facts so stated and recited. The
Trustee or his successor or substitute may appoint or delegate any one or more
persons as agent to perform any act or acts necessary or incident to any sale
held by Trustee, including the posting of notices and the conduct of sale, but
in the name and on behalf of Trustee, his successor or substitute. If Trustee or
his successor or substitute shall have given notice of sale hereunder, any
successor or substitute Trustee thereafter appointed may complete the sale and
the conveyance of the property pursuant thereto as if such notice had been given
by the successor or substitute Trustee conducting the sale.

     (d) UNIFORM COMMERCIAL CODE. Without limitation of Agent's rights of
enforcement with respect to the Collateral or any part thereof in accordance
with the procedures for foreclosure of real estate, Agent may exercise its
rights of enforcement with respect to the Collateral or any part thereof under
the Texas Business and Commerce Code as amended (or under the Uniform Commercial
Code in force in any other state to the extent the same is applicable law) and
in conjunction with, in addition to or in substitution for those rights and
remedies: (1) Agent may enter upon Grantor's premises to take possession of,

Page 51
<PAGE>
 
assemble and collect the Collateral or, to the extent and for those items of the
Collateral permitted under applicable law, to render it unusable; (2) Agent may
require Grantor to assemble the Collateral and make it available at a place
Agent designates which is mutually convenient to allow Agent to take possession
or dispose of the Collateral; (3) written notice mailed to Grantor as provided
herein at least ten (10) days prior to the date of public sale of the Collateral
or prior to the date after which private sale of the Collateral will be made
shall constitute reasonable notice; (4) any sale made pursuant to the provisions
of this paragraph shall be deemed to have been a public sale conducted in a
commercially reasonable manner ifheld contemporaneously with and upon the same
notice as required for the sale of the Mortgaged Property under power of sale as
provided in paragraph (c) above in this SECTION 5.1; (5) in the event of a
foreclosure sale, whether made by Trustee under the terms hereof, or under
judgment of a court, the Collateral and the other Mortgaged Property may, at the
option of Agent, be sold as a whole; (6) it shall not be necessary that Agent
take possession of the Collateral or any part thereof prior to the time that any
sale pursuant to the provisions of this SECTION is conducted and it shall not be
necessary that the Collateral or any part thereof be present at the location of
such sale; (7) with respect to application of proceeds of disposition of the
Collateral under SECTION 5.3 hereof, the costs and expenses incident to 
disposi tion shall include the reasonable expenses of retaking, holding,
preparing for sale or lease, selling, leasing and the like and the reasonable
attorneys' fees and legal expenses incurred by Agent; (8) any and all statements
of fact or other recitals made in any bill of sale or assignment or other
instrument evidencing any foreclosure sale hereunder as to nonpayment of the
secured indebtedness or as to the occurrence of any default, or as to Agent
having declared all of such indebtedness to be due and payable, or as to notice
of time, place and terms of sale and of the properties to be sold having been
duly given, or as to any other act or thing having been duly done by Agent,
shall be taken as prima facie evidence of the truth of the facts so stated and
recited; and (9) Agent may appoint or delegate any one or more persons as agent
to perform any act or acts necessary or incident to any sale held by Agent,
including the sending of notices and the conduct of the sale, but in the name
and on behalf of Agent.

     (e) LAWSUITS.  Agent may proceed by a suit or suits in equity or at law,
whether for collection of the indebtedness secured hereby, 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 Property under the judgment or decree of any court or
courts of competent jurisdiction.

     (f) ENTRY ON MORTGAGED PROPERTY.  Agent is authorized, prior or subsequent
to the institution of any foreclosure proceedings, to the fullest extent
permitted by applicable law, to enter upon the Mortgaged Property, or any part
thereof, and to take possession of the Mortgaged Property and all books and
records relating thereto, and to exercise without interference from Grantor any
and all rights which Grantor has with respect to the management, possession,
operation, protection or preservation of the Mortgaged Property.  Agent shall
not be deemed to have taken possession of the Mortgaged Property or any part
thereof except upon the exercise of its right to do so, and then only to the
extent evidenced by its demand and overt act specifically for such purpose.  All
costs, expenses and liabilities of every character incurred by Agent in
managing, operating, maintaining, protecting or preserving the Mortgaged
Property shall constitute a demand obligation of Grantor (which obligation
Grantor hereby promises to pay) to Agent pursuant to this Deed of Trust.  If
necessary to obtain the possession provided for above, Agent may invoke any and
all legal remedies to dispossess Grantor.  In connection with any action taken
by Agent pursuant to this SECTION, Agent shall not be liable for any loss
sustained by Grantor resulting from any failure to let the Mortgaged Property or
any part thereof, or from any act or omission of Agent in managing the Mortgaged
Property unless such loss is caused by the willful misconduct and bad faith of
Agent, nor shall Agent be obligated to perform or discharge any obligation,
duty, or liability of Grantor arising under any lease or other agreement
relating to the Mortgaged Property or arising under any Permitted Encumbrance or
otherwise arising.  Grantor hereby assents to, ratifies and confirms any and all
actions of Agent with respect to the Mortgaged Property taken under this
SECTION.

     (g) RECEIVER.  Agent shall as a matter of right be entitled to the
appointment of a receiver or 

Page 52
<PAGE>
 
receivers for all or any part of the Mortgaged Property, whether such
receivership be incident to a proposed sale (or sales) of such property or
otherwise, and without regard to the value of the Mortgaged Property or the
solvency of any person or persons liable for the payment of the indebtedness
secured hereby, and Grantor does hereby irrevocably consent to the appointment
of such receiver or receivers, waives any and all defenses to such appointment,
agrees not to oppose any application therefor by Agent, and agrees that such
appointment shall in no manner impair, prejudice or otherwise affect the rights
of Agent to application of Rents as provided in this Deed of Trust. Nothing
herein is to be construed to deprive Agent of any other right, remedy, or
privilege it may have under the law to have a receiver appointed. Any money
advanced by Agent in connection with any such receivership shall be a demand
obligation (which obligation Grantor hereby promises to pay) owing by Grantor to
Agent pursuant to this Deed of Trust.

     (h) TERMINATION OF COMMITMENT TO LEND.  Agent may terminate any commitment
or obligation of Holders to lend or disburse funds under any Loan Document.

     (i) OTHER RIGHTS AND REMEDIES.  Agent and each Holder may exercise any and
all other rights and remedies which Agent and such Holder may have under the
Loan Documents, or at law or in equity or otherwise.

     Section 5.2. EFFECTIVE AS DEED OF TRUST. This instrument shall be effective
as a mortgage as well as a deed of trust and upon the occurrence of a default
may be foreclosed as to any of the Mortgaged Property in any manner permitted by
applicable law, and any foreclosure suit may be brought by Trustee or by Agent;
and to the extent, if any, required to cause this instrument to be so effective
as a mortgage as well as a deed of trust, Grantor hereby mortgages the Mortgaged
Property to Agent, for the benefit of Holders. In the event a foreclosure
hereunder shall be commenced by Trustee, or his substitute or successor, Agent
may at any time before the sale of the Mortgaged Property direct Trustee to
abandon the sale, and may then institute suit for the collection of the Notes
and/or any other secured indebtedness, and for the foreclosure of this Deed of
Trust.  It is agreed that if Agent or any Holder should institute a suit for the
collection of the Note or any other secured indebtedness and for the foreclosure
of this Deed of Trust, Agent may at any time before the entry of a final
judgment in said suit dismiss the same, and require Trustee, his substitute or
successor to sell the Mortgaged Property in accordance with the provisions of
this Deed of Trust.

     Section 5.3.  PROCEEDS OF FORECLOSURE.  The proceeds of any sale held by
Trustee or Agent or any receiver or public officer in foreclosure of the liens
and security interests evidenced hereby shall be applied to the secured
indebtedness as provided in the Credit Agreement.

     Section 5.4.  AGENT AS PURCHASER.  Agent, for itself or on behalf of
Holders, shall have the right to become the purchaser at any sale held by
Trustee or substitute or successor or by any receiver or public officer or at
any public sale, and Holders shall have the right to credit upon the amount of
Agent's successful bid, to the extent necessary to satisfy such bid, all or any
part of the secured indebtedness in such manner and order as required by the
Credit Agreement.

     Section 5.5.  FORECLOSURE AS TO MATURED DEBT.  Upon the occurrence of a
default, Agent shall have the right to proceed with foreclosure (judicial or
nonjudicial) of the liens and security interests hereunder without declaring the
entire secured indebtedness due, and in such event any such foreclosure sale may
be made subject to the unmatured part of the secured indebtedness; and any such
sale shall not in any manner affect the unmatured part of the secured
indebtedness, but as to such unmatured part this Deed of Trust shall remain in
full force and effect just as though no sale had been made. The proceeds of such
sale shall be applied as provided in SECTION 5.3 hereof.  Several sales may be
made hereunder without exhausting the right of sale for any unmatured part of
the secured indebtedness.

Page 53
<PAGE>
 
     Section 5.6.  REMEDIES CUMULATIVE. All rights and remedies provided for
herein and in any other Loan Document are cumulative of each other and of any
and all other rights and remedies existing at law or in equity, and Trustee,
Agent and Holders shall, in addition to the rights and remedies provided herein
or in any other Loan Document, be entitled to avail themselves of all such other
rights and remedies as may now or hereafter exist at law or in equity for the
collection of the secured indebtedness and the enforcement of the covenants
herein and the foreclosure of the liens and security interests evidenced hereby,
and the resort to any right or remedy provided for hereunder or under any such
other Loan Document or provided for by law or in equity shall not prevent the
concurrent or subsequent employment of any other appropriate right or rights or
remedy or remedies.

     Section 5.7.  AGENT'S AND HOLDERS' DISCRETION AS TO SECURITY.  Agent and
Holders may resort to any security given by this Deed of Trust or to any other
security now existing or hereafter given to secure the payment of the secured
indebtedness, in whole or in part, and in such portions and in such order as
provided in the Credit Agreement, and any such action shall not in anywise be
considered as a waiver of any of the rights, benefits, liens, or security
interests evidenced by this Deed of Trust.

     Section 5.8.  GRANTOR'S WAIVER OF CERTAIN RIGHTS. To the full extent
Grantor may do so, Grantor agrees that Grantor will not at any time insist upon,
plead, claim or take the benefit or advantage of any law now or hereafter in
force providing for any appraisement, valuation, stay, extension or redemption,
and Grantor, for Grantor, Grantor's heirs, devisees, representatives, successors
and assigns, and for any and all persons ever claiming any interest in the
Mortgaged Property, to the extent permitted by applicable law, hereby waives and
releases all rights of redemption, valuation, appraisement, stay of execution,
notice of intention to mature or declare due the whole of the secured
indebtedness, notice of election to mature or declare due the whole of the
secured indebtedness and all rights to a marshaling of assets of Grantor,
including the Mortgaged Property, or to a sale in inverse order of alienation in
the event of foreclosure of the liens and/or security interests hereby created.
Grantor shall not have or assert any right under any statute or rule of law
pertaining to the marshaling of assets, sale in inverse order of alienation, the
exemption of homestead, the administration of estates of decedents, or other
matters whatever to defeat, reduce or affect the right of Agent under the terms
of this Deed of Trust to a sale of the Mortgaged Property for the collection of
the secured indebtedness without any prior or different resort for collection,
or the right of Agent under the terms of this Deed of Trust to the payment of
the secured indebtedness out of the proceeds of sale of the Mortgaged Property
in preference to every other claimant whatever. Grantor waives any right or
remedy which Grantor may have or be able to assert pursuant to Chapter 34 of the
Texas Business and Commerce Code, or any other provision of Texas law,
pertaining to the rights and remedies of sureties. If any law referred to in
this SECTION and now in force, of which Grantor or Grantor's heirs, devisees,
representatives, successors or assigns or any other persons claiming any
interest in the Mortgaged Property might take advantage despite this SECTION,
shall hereafter be repealed or cease to be in force, such law shall not
thereafter be deemed to preclude the application of this SECTION.

     Section 5.9.  DELIVERY OF POSSESSION AFTER FORECLOSURE.  In the event there
is a foreclosure sale hereunder and at the time of such sale, Grantor or
Grantor's heirs, devisees, representatives, successors or assigns are occupying
or using the Mortgaged Property, or any part thereof, each and all shall
immediately become the tenant of the purchaser at such sale, which tenancy shall
be a tenancy from day to day, terminable at the will of either landlord or
tenant, at a reasonable rental per day based upon the value of the property
occupied, such rental to be due daily to the purchaser; and to the extent
permitted by applicable law, the purchaser at such sale shall, notwithstanding
any language herein apparently to the contrary, have the sole option to demand
immediate possession following the sale or to permit the occupants to remain as
tenants at will. In the event the tenant fails to surrender possession of said
property upon demand, the purchaser shall be entitled to institute and maintain
a summary action for possession of the property (such as an action for forcible
detainer) in any court having jurisdiction.

                                 MISCELLANEOUS

     Section 6.1.  SCOPE OF DEED OF TRUST.  This Deed of Trust is a deed of
trust and mortgage of both real and personal property, a security agreement, a
financing statement and a collateral assignment, and also covers proceeds and
fixtures.

     Section 6.2.  EFFECTIVE AS A FINANCING STATEMENT.  This Deed of Trust shall
be effective as a financing statement filed as a fixture filing with respect to
all fixtures included within the Mortgaged Property and is to be filed for
record in the real estate records of each county where any part of the Mortgaged
Property (including said fixtures) is situated.  This Deed of Trust shall also
be effective as a financing statement covering minerals or the like (including
oil and gas) and accounts subject to Subsection (e) of Section 9.103 of the
Texas Business and Commerce Code, as amended, and similar provisions (if any) of
the Uniform Commercial Code as enacted in any other state where the Mortgaged
Property is situated which will be financed at the wellhead or minehead of the
wells or mines located on the Mortgaged Property and is to be filed for record
in the real estate records of each county where any part of the Mortgaged
Property is situated.  This Deed of Trust shall also be effective as a financing
statement covering any other Mortgaged Property and may be filed in any other
appropriate filing or recording office.  The mailing address of Grantor is the
address of Grantor set forth at the end of this Deed of Trust and the address of
Agent from which information concerning the security interests hereunder may be
obtained is the address of Agent set forth at the end of this Deed of Trust.  A
carbon, photographic or other reproduction of this Deed of Trust or of any
financing statement relating to this Deed of Trust shall be sufficient as a
financing statement for any of the purposes referred to in this SECTION.

     Section 6.3.  NOTICE TO ACCOUNT DEBTORS.  In addition to the rights granted
elsewhere in this Deed of Trust, Agent may at any time notify the account
debtors or obligors of any accounts, chattel paper, negotiable instruments or
other evidences of indebtedness included in the Collateral to pay Agent
directly.

     Section 6.4.  WAIVER BY AGENT.  Agent may at any time and from time-to-time
by a specific writing intended for the purpose:  (a) waive compliance by Grantor
with any covenant herein made by Grantor to the extent and in the manner
specified in such writing; (b) consent to Grantor's doing any act which
hereunder Grantor is prohibited from doing, or to Grantor's failing to do any
act which hereunder Grantor is required to do, to the extent and in the manner
specified in such writing; (c) release any part of the Mortgaged Property or any
interest therein from the lien and security interest of this Deed of Trust,
without the joinder of Trustee; or (d) release any party liable, either directly
or indirectly, for the secured indebtedness or for any covenant herein or in any
other Loan Document, without impairing or releasing the liability of any other
party.  No such act shall in any way affect the rights or powers of Agent, any
Holder or Trustee hereunder except to the extent specifically agreed to by Agent
or any Holder in such writing.

     Section 6.5.  NO IMPAIRMENT OF SECURITY.  The lien, security interest and
other security rights of Agent hereunder or under any other Loan Document shall
not be impaired by any indulgence, moratorium or release granted by Agent
including, but not limited to, any renewal, extension or modification which
Agent may grant with respect to any secured indebtedness, or any surrender,
compromise, release, renewal, extension, exchange or substitution which Agent
may grant in respect of the Mortgaged Property, or any part thereof or any
interest therein, or any release or indulgence granted to any endorser,
guarantor or surety of any secured indebtedness.  The taking of additional
security by Agent shall not release or impair the lien, security interest, or
other security rights of Agent hereunder or affect the liability of Grantor or
of any endorser, guarantor or surety, or improve the right of any junior
lienholder in the Mortgaged Property 

Page 55
<PAGE>
 
(without implying hereby Agent's consent to any junior lien).

     Section 6.6.  ACTS NOT CONSTITUTING WAIVER BY AGENT.  Agent may waive any
default without waiving any other prior or subsequent default.  Agent may remedy
any default without waiving the default remedied.  Neither failure by Agent to
exercise, nor delay by Agent in exercising, nor discontinuance of the exercise
of any right, power or remedy (including but not limited to the right to
accelerate the maturity of the secured indebtedness or any part thereof) upon or
after any default shall be construed as a waiver of such default or as a waiver
of the right to exercise any such right, power or remedy at a later date.  No
single or partial exercise by Agent of any right, power or remedy hereunder
shall exhaust the same or shall preclude any other or further exercise thereof,
and every such right, power or remedy hereunder may be exercised at any time and
from time-to-time.  No modification or waiver of any provision hereof nor
consent to any departure by Grantor therefrom shall in any event be effective
unless the same shall be in writing and signed by Agent and then such waiver or
consent shall be effective only in the specific instance, for the purpose for
which given and to the extent therein specified.  No notice to nor demand on
Grantor in any case shall of itself entitle Grantor to any other or further
notice or demand in similar or other circumstances.  Remittances in payment of
any part of the secured indebtedness other than in the required amount in
immediately available U.S. funds shall not, regardless of any receipt or credit
issued therefor, constitute payment until the required amount is actually
received by Agent in immediately available U.S. funds and shall be made and
accepted subject to the condition that any check or draft may be handled for
collection in accordance with the practice of the collecting bank or banks.
Acceptance by Agent of any payment in an amount less than the amount then due on
any secured indebtedness shall be deemed an acceptance on account only and shall
not in any way excuse the existence of a default hereunder.

     Section 6.7.  GRANTOR'S SUCCESSORS. If the ownership of the Mortgaged
Property or any part thereof becomes vested in a person other than Grantor,
Agent may, without notice to Grantor, deal with such successor or successors in
interest with reference to this Deed of Trust and to the indebtedness secured
hereby in the same manner as with Grantor, without in any way vitiating or
discharging Grantor's liability hereunder or for the payment of the indebtedness
or performance of the obligations secured hereby.  No transfer of the Mortgaged
Property, no forbearance on the part of Agent, and no extension of the time for
the payment of the indebtedness secured hereby given by Agent shall operate to
release, discharge, modify, change or affect, in whole or in part, the liability
of Grantor hereunder for the payment of the indebtedness or performance of the
obligations secured hereby or the liability of any other person hereunder for
the payment of the indebtedness secured hereby.  Each Grantor agrees that it
shall be bound by any modification of this Deed of Trust or any of the other
Loan Documents made by Agent and any subsequent owner of the Mortgaged Property,
with or without notice to such Grantor, and no such modifications shall impair
the obligations of such Grantor under this Deed of Trust or any other Loan
Document.  Nothing in this SECTION or elsewhere in this Deed of Trust shall be
construed to imply Agent's consent to any transfer of the Mortgaged Property.

     Section 6.8.  PLACE OF PAYMENT; FORUM.  All secured indebtedness which may
be owing hereunder at any time by Grantor shall be payable at the place
designated in the Notes (or if no such designation is made, at the address of
Agent indicated at the end of this Deed of Trust).  Grantor hereby irrevocably
submits generally and unconditionally for itself and in respect of its property
to the non-exclusive jurisdiction of any Texas state court, or any United States
federal court, sitting in the county in which the secured indebtedness is
payable, and to the non exclusive jurisdiction of any state or United States
federal court sitting in the state in which any of the Mortgaged Property is
located, over any suit, action or proceeding arising out of or relating to this
Deed of Trust or the secured indebtedness.  Grantor hereby agrees and consents
that, in addition to any methods of service of process provided for under
applicable law, all service of process in any such suit, action or proceeding in
any Texas state court, or any United States federal court, sitting in the county
in which the secured indebtedness is payable may be made by certified or
registered mail, return receipt requested, directed to Grantor at its address
stated in this Deed of Trust, or at a subsequent address of Grantor of which
Agent received actual notice from Grantor in 

Page 56
<PAGE>
 
accordance with this Deed of Trust, and service so made shall be complete five
(5) days after the same shall have been so mailed.

     Section 6.9.  SUBROGATION TO EXISTING LIENS; VENDOR'S LIEN.  To the extent
that proceeds of the Notes are used to pay indebtedness secured by any
outstanding lien, security interest, charge or prior encumbrance against the
Mortgaged Property, such proceeds have been advanced by Holder at Grantor's
request, and Agent shall be subrogated to any and all rights, security interests
and liens owned by any owner or holder of such outstanding liens, security
interests, charges or encumbrances, however remote, irrespective of whether said
liens, security interests, charges or encumbrances are released, and all of the
same are recognized as valid and subsisting and are renewed and continued and
merged herein to secure the secured indebtedness, but the terms and provisions
of this Deed of Trust shall govern and control the manner and terms of
enforcement of the liens, security interests, charges and encumbrances to which
Agent is subrogated hereunder.  It is expressly understood that, in
consideration of the payment of such indebtedness by Agent, Grantor hereby
waives and releases all demands and causes of action for offsets and payments in
connection with the said indebtedness.  If all or any portion of the proceeds of
the loan evidenced by the Credit Agreement and the Notes or of any other secured
indebtedness has been advanced for the purpose of paying the purchase price for
all or a part of the Mortgaged Property, no vendor's lien is waived; and Agent
shall have, and is hereby granted, a vendor's lien on the Mortgaged Property as
cumulative additional security for the secured indebtedness.  Agent may
foreclose under this Deed of Trust or under the vendor's lien without waiving
the other or may foreclose under both.

     Section 6.10. APPLICATION OF PAYMENTS TO CERTAIN INDEBTEDNESS.  If any
part of the secured indebtedness cannot be lawfully secured by this Deed of
Trust or if any part of the Mortgaged Property cannot be lawfully subject to the
lien and security interest hereof to the full extent of such indebtedness, then
all payments made shall be applied on said indebtedness first in discharge of
that portion thereof which is not secured by this Deed of Trust.

     Section 6.11. COMPLIANCE WITH USURY LAWS. It is the intent of Grantor,
Agent, and Holders and all other parties to the Loan Documents to conform to and
contract in strict compliance with applicable usury law from time-to-time in
effect. All agreements between Agent, Holders, and Grantor (or any other party
liable with respect to any indebtedness under the Loan Documents) are hereby
limited by the provisions of this SECTION which shall override and control all
such agreements, whether now existing or hereafter arising. In no way, nor in
any event or contingency (including but not limited to prepayment, default,
demand for payment, or acceleration of the maturity of any obligation), shall
the interest taken, reserved, contracted for, charged, chargeable, or received
under this Deed of Trust, the Credit Agreement, the Notes or any other Loan
Document or otherwise, exceed the maximum nonusurious amount permitted by
applicable law (the "Maximum Amount").  If, from any possible construction of
any document, interest would otherwise be payable in excess of the Maximum
Amount, any such construction shall be subject to the provisions of this SECTION
and such document shall ipso facto be automatically reformed and the interest
payable shall be automatically reduced to the Maximum Amount, without the
necessity of execution of any amendment or new document.  If Agent or any Holder
shall ever receive anything of value which is characterized as interest under
applicable law and which would apart from this provision be in excess of the
Maximum Amount, an amount equal to the amount which would have been excessive
interest shall, without penalty, be applied to the reduction of the principal
amount owing on the secured indebtedness in the inverse order of its maturity
and not to the payment of interest, or refunded to Grantor or the other payor
thereof if and to the extent such amount which would have been excessive exceeds
such unpaid principal.  The right to accelerate maturity of the Notes or any
other secured indebtedness does not include the right to accelerate any interest
which has not otherwise accrued on the date of such acceleration, and Holders do
not intend to charge or receive any unearned interest in the event of
acceleration.  All interest paid or agreed to be paid to Holders shall, to the
extent permitted by applicable law, be amortized, prorated, allocated and spread
throughout the full stated term (including any renewal or extension) of such
indebtedness so that the amount of interest on account of such indebtedness does
not exceed the Maximum 

Page 57
<PAGE>
 
Amount. As used in this SECTION, the term "applicable law" shall mean the laws
of the State of Texas or the federal laws of the United States applicable to
this transaction, whichever laws allow the greater interest, as such laws now
exist or may be changed or amended or come into effect in the future.

     Section 6.12. SUBSTITUTE TRUSTEE.  The Trustee may resign by an instrument
in writing addressed to Agent, or Trustee may be removed at any time with or
without cause by an instrument in writing executed by Agent.  In case of the
death, resignation, removal, or disqualification of Trustee, or if for any
reason Agent shall deem it desirable to appoint a substitute or successor
trustee to act instead of the herein named trustee or any substitute or
successor trustee, then Agent shall have the right and is hereby authorized and
empowered to appoint a successor trustee, or a substitute trustee, without other
formality than appointment and designation in writing executed by Agent and the
authority hereby conferred shall extend to the appointment of other successor
and substitute trustees successively until the indebtedness secured hereby has
been paid in full, or until the Mortgaged Property is fully and finally sold
hereunder.  If Agent is a corporation or association and such appointment is
executed on its behalf by an officer of such corporation or association, such
appointment shall be conclusively presumed to be executed with authority and
shall be valid and sufficient without proof of any action by the board of
directors or any superior officer of the corporation or association.  Upon the
making of any such appointment and designation, all of the estate and title of
Trustee in the Mortgaged Property shall vest in the named successor or
substitute Trustee and he shall thereupon succeed to, and shall hold, possess
and execute, all the rights, powers, privileges, immunities and duties herein
conferred upon Trustee.  All references herein to "Trustee" shall be deemed to
refer to Trustee (including any successor or substitute appointed and designated
as herein provided) from time-to-time acting hereunder.

     Section 6.13. NO LIABILITY OF TRUSTEE. The Trustee shall not be liable for
any error of judgment or act done by Trustee in good faith, or be otherwise
responsible or accountable under any circumstances whatsoever (including
Trustee's negligence), except for Trustee's gross negligence or willful
misconduct.  The Trustee shall have the right to rely on any instrument,
document or signature authorizing or supporting any action taken or proposed to
be taken by him hereunder, believed by him in good faith to be genuine.  All
moneys received by Trustee shall, until used or applied as herein provided, be
held in trust for the purposes for which they were received, but need not be
segregated in any manner from any other moneys (except to the extent required by
law), and Trustee shall be under no liability for interest on any moneys
received by him hereunder.  Grantor hereby ratifies and confirms any and all
acts which the herein named Trustee or his successor or successors, substitute
or substitutes, in this trust, shall do lawfully by virtue hereof.  Grantor will
reimburse Trustee for, and save him harmless against, any and all liability and
expenses which may be incurred by him in the performance of his duties.  The
foregoing indemnity shall not terminate upon discharge of the secured
indebtedness or foreclosure, or release or other termination, of this Deed of
Trust.

     Section 6.14. RELEASE OF DEED OF TRUST.  If all of the secured
indebtedness be paid as the same becomes due and payable and all of the
covenants, warranties, undertakings and agreements made in this Deed of Trust
are kept and performed, and all obligations, if any, of Holders for further
advances have been terminated, then, and in that event only, all rights under
this Deed of Trust shall terminate (except to the extent expressly provided
herein with respect to indemnifications, representations and warranties and
other rights which are to continue following the release hereof) and the
Mortgaged Property shall become wholly clear of the liens, security interests,
conveyances and assignments evidenced hereby, and such liens and security
interests shall be released by Agent in due form at Grantor's cost.  Without
limitation, all provisions herein for indemnity of Agent, Holders, or Trustee
shall survive discharge of the secured indebtedness and any foreclosure, release
or termination of this Deed of Trust.

     Section 6.15. NOTICES.  All notices, requests, consents, demands and other
communications required or which any party desires to give hereunder or under
any other Loan Document shall be in writing 

Page 58
<PAGE>
 
and, unless otherwise specifically provided in such other Loan Document, shall
be deemed sufficiently given or furnished if delivered by personal delivery, by
courier, or by registered or certified United States mail, postage prepaid,
addressed to the party to whom directed at the addresses specified at the end of
this Deed of Trust (unless changed by similar notice in writing given by the
particular party whose address is to be changed) or by telegram, telex, or
facsimile. Any such notice or communication shall be deemed to have been given
either at the time of personal delivery or, in the case of courier or mail, as
of the date of first attempted delivery at the address and in the manner
provided herein, or, in the case of telegram, telex or facsimile, upon receipt;
provided that, service of a notice required by Texas Property Code Section
51.002, as amended, shall be considered complete when the requirements of that
statute are met. Notwithstanding the foregoing, no notice of change of address
shall be effective except upon receipt. This SECTION shall not be construed in
any way to affect or impair any waiver of notice or demand provided in any Loan
Document or to require giving of notice or demand to or upon any person in any
situation or for any reason.

     Section 6.16. INVALIDITY OF CERTAIN PROVISIONS.  A determination that any
provision of this Deed of Trust is unenforceable or invalid shall not affect the
enforceability or validity of any other provision and the determination that the
application of any provision of this Deed of Trust to any person or circumstance
is illegal or unenforceable shall not affect the enforceability or validity of
such provision as it may apply to other persons or circumstances.

     Section 6.17. GENDER; TITLES; CONSTRUCTION.  Within this Deed of Trust,
words of any gender shall be held and construed to include any other gender, and
words in the singular number shall be held and construed to include the plural,
unless the context otherwise requires.  Titles appearing at the beginning of any
subdivisions hereof are for convenience only, do not constitute any part of such
subdivisions, and shall be disregarded in construing the language contained in
such subdivisions.  The use of the words "herein," "hereof," "hereunder" and
other similar compounds of the word "here" shall refer to this entire Deed of
Trust and not to any particular ARTICLE, SECTION, paragraph or provision.  The
term "person" and words importing persons as used in this Deed of Trust shall
include firms, associations, partnerships (including limited partnerships),
joint ventures, trusts, corporations and other legal entities, including public
or governmental bodies, agencies or instrumentalities, as well as natural
persons.

     Section 6.18. REPORTING COMPLIANCE.  Grantor agrees to comply with any and
all reporting requirements applicable to the transaction evidenced by the Notes
and secured by this Deed of Trust which are set forth in any law, statute,
ordinance, rule, regulation, order or determination of any governmental
authority, including but not limited to The International Investment Survey Act
of 1976, The Agricultural Foreign Investment Disclosure Act of 1978, The Foreign
Investment in Real Property Tax Act of 1980 and the Tax Reform Act of 1984 and
further agrees upon request of Agent to furnish Agent with evidence of such
compliance.

     Section 6.19. AGENT'S CONSENT.  Except where otherwise expressly provided
herein, in any instance hereunder where the approval, consent or the exercise of
judgment of Agent is required or requested, (i) the granting or denial of such
approval or consent and the exercise of such judgment shall be within the sole
discretion of Agent, and Agent shall not, for any reason or to any extent, be
required to grant such approval or consent or exercise such judgment in any
particular manner, regardless of the reasonableness of either the request or
Agent's judgment, and (ii) no approval or consent of Agent shall be deemed to
have been given except by a specific writing intended for the purpose and
executed by an authorized representative of Agent.

     Section 6.20. GRANTOR.  Unless the context clearly indicates otherwise, as
used in this Deed of Trust, "Grantor" means the grantors named in SECTION 1.1
hereof or any of them.  The obligations of Grantor hereunder shall be joint and
several.  If any Grantor, or any signatory who signs on behalf of any Grantor,
is a corporation, partnership or other legal entity, Grantor and any such
signatory, and the person or persons signing for it, represent and warrant to
Agent that this instrument is executed, acknowledged and 

Page 59
<PAGE>
 
delivered by Grantor's duly authorized representatives. If Grantor is an
individual, no power of attorney granted by Grantor herein shall terminate on
Grantor's disability.

     Section 6.21.  EXECUTION; RECORDING.  This Deed of Trust has been executed
in several counterparts, all of which are identical, and all of which
counterparts together shall constitute one and the same instrument. The date or
dates reflected in the acknowledgments hereto indicate the date or dates of
actual execution of this Deed of Trust, but such execution is as of the date
shown on the first page hereof, and for purposes of identification and reference
the date of this Deed of Trust shall be deemed to be the date reflected on the
first page hereof. Grantor will cause this Deed of Trust and all amendments and
supplements thereto and substitutions therefor and all financing statements and
continuation statements relating thereto to be recorded, filed, re-recorded and
refiled in such manner and in such places as Trustee or Agent shall reasonably
request and will pay all such recording, filing, re-recording and refiling
taxes, fees and other charges.

     Section 6.22.  SUCCESSORS AND ASSIGNS.  The terms, provisions, covenants
and conditions hereof shall be binding upon Grantor, and the heirs, devisees,
representatives, successors and assigns of Grantor, and shall inure to the
benefit of Trustee and Agent and shall constitute covenants running with the
Land. All references in this Deed of Trust to Grantor shall be deemed to include
all such heirs, devisees, representatives, successors and assigns of Grantor.

     Section 6.23.  MODIFICATION OR TERMINATION.  The Loan Documents may only be
modified or terminated by a written instrument or instruments intended for that
purpose and executed by the party against which enforcement of the modification
or termination is asserted. Any alleged modification or termination which is not
so documented shall not be effective as to any party.

     Section 6.24.  NO PARTNERSHIP, ETC.  The relationship between Agent,
Holders, and Grantor is solely that of agent, lender and borrower. Neither Agent
nor any Holder has any fiduciary or other special relationship with Grantor.
Nothing contained in the Loan Documents is intended to create any partnership,
joint venture, association or special relationship between Grantor, Agent, or
Holders or in any way make Agent or any Holder a co-principal with Grantor with
reference to the Mortgaged Property. All agreed contractual duties between or
among Agent, Holders, Grantor, and Trustee are set forth herein and in the other
Loan Documents and any additional implied covenants or duties are hereby
disclaimed. Any inferences to the contrary of any of the foregoing are hereby
expressly negated.

     Section 6.25.  APPLICABLE LAW.  This Deed of Trust, and its validity,
enforcement and interpretation, shall be governed by Texas law (without regard
to any conflict of laws principles) and applicable United States federal law.

     Section 6.26.  ENTIRE AGREEMENT.  The Loan Documents constitute the entire
understanding and agreement between Grantor, Agent, and Holders with respect to
the transactions arising in connection with the indebtedness secured hereby and
supersede all prior written or oral understandings and agreements between
Grantor, Agent, and Holders with respect to the matters addressed in the Loan
Documents. Grantor hereby acknowledges that, except as incorporated in writing
in the Loan Documents, there are not, and were not, and no persons are or were
authorized by Agent or Holders to make, any representations, understandings,
stipulations, agreements or promises, oral or written, with respect to the
matters addressed in the Loan Documents.

     THE WRITTEN LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE
PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR
SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.

                    FORM OF ASSIGNMENT OF LEASES AND RENTS

                        ASSIGNMENT OF LEASES AND RENTS

     THIS ASSIGNMENT OF LEASES AND RENTS (the "ASSIGNMENT") is made as of
________________, 19___, by PRENTISS PROPERTIES ACQUISITION PARTNERS, L.P., a
Delaware limited partnership ("ASSIGNOR"), to BANK ONE, TEXAS, N.A., for itself
and as Administrative Agent for the Lenders defined below (in such capacity,
together with its successors and assigns, "ASSIGNEE").

                             W I T N E S S E T H:
                             - - - - - - - - - - 

     1.  Assignor, Assignee, NationsBank of Texas, N.A., as Documentation Agent,
and certain other lenders (such lenders together with Assignee in its capacity
as a lender are collectively referred to herein as the "LENDERS") have entered
into that certain Credit Agreement (as from time-to-time amended, supplemented,
or restated, the "CREDIT AGREEMENT") dated as of October 17, 1996.

     2.  Assignor has delivered those certain Revolving Credit Notes (together
with all renewals, extensions, substitutions, replacements, and modifications
thereof, the "NOTES"), dated of even date with the Credit Agreement in the
aggregate original principal amount of $100,000,000.00, payable to the order of
the Lenders.

     3.  The obligations of Assignor under the Credit Agreement and the Notes
are secured by, among other collateral, liens and security interests pursuant to
that certain Deed of Trust, Assignment, Security Agreement, and  Financing
Statement (the "DEED OF TRUST") dated of even date herewith, executed by
Assignor in favor of Robert F. Nelson, Trustee, covering certain real estate in
____________ County, _________, more fully described on EXHIBIT A attached
hereto and incorporated herein by reference, along with the related and
appurtenant improvements, fixtures and personal property, and related interests
described therein (collectively, the "MORTGAGED PROPERTIES").

     4.  All capitalized terms not otherwise defined herein shall have the
meanings assigned to such terms in the Credit Agreement.

     5.  The Mortgaged Properties are and, from time-to-time, may be, leased, in
whole or in part, to certain third parties.

     6.  The parties hereto wish to provide an additional source of payment of
the Obligation (as such term is defined in the Credit Agreement).

     NOW, THEREFORE, for and in consideration of the loan made to Assignor by
Lenders, and for other good and valuable consideration, the receipt and legal
sufficiency of which are hereby acknowledged, Assignor hereby agrees as follows:

Page 1
<PAGE>
 
                            ARTICLE I:  ASSIGNMENT

1.1  Assignor does hereby grant, transfer, and assign unto Assignee the
following:

          A.  All of Assignor's right, title, and interest in and to all present
     and future ground leases, space leases, subleases or other agreements or
     arrangements, whether written or oral, and all agreements for the use or
     occupancy of any portion of the Mortgaged Properties, together with any and
     all extensions or renewals of said leases and agreements and any and all
     future leases or agreements upon or covering the use or occupancy of all or
     any part of the Mortgaged Properties, all such leases, agreements,
     subleases, and tenancies, whether now or in the future existing, being
     hereinafter collectively referred to as the "LEASES;"

          B.  Any and all guaranties of performance by lessees under any of the
     Leases; and

          C.  The immediate and continuing right to collect and receive all of
     the rents, royalties, bonuses, income, receipts, revenues, issues, profits
     and other benefits derived from the Mortgaged Properties or any part
     thereof, or the occupation, use or enjoyment of the Mortgaged Properties,
     or any part thereof, or from any Lease, and including, but not limited to,
     minimum rents, additional rents, percentage rents, common area maintenance
     charges, parking charges, tax and insurance premium contributions, and
     liquidated damages following default, premiums payable by any lessee upon
     the exercise of any cancellation privilege provided for in any of the
     Leases, and all proceeds payable under any policy of insurance covering the
     loss of rent resulting from untenantability caused by destruction or damage
     of the Mortgaged Properties, together with any and all rights and claims of
     any kind which Assignor may have against any lessee under the Leases or
     against any subtenants or occupants of the Mortgaged Properties, all such
     monies, rights and claims in this paragraph described being hereinafter
     referred to as the "RENTS."

1.2       A.  Until Assignee notifies Assignor of a Default (as defined in the
     Credit Agreement), Assignor shall collect Rents directly from each lessee,
     sublessee, tenant, or other person having the right to occupy, use, or
     manage the Mortgaged Properties, or any part thereof, under the Leases
     (being hereinafter collectively referred to as the "LESSEES"), and the
     Lessees may pay Rents directly to Assignor, but Assignor covenants to hold
     the Rents in trust, to be applied, and Assignor covenants to apply the
     Rents, to (a) payment and performance of the Notes and the remaining
     Obligation and (b) reasonable and necessary expenses of and charges with
     respect to the ownership, maintenance and operation of the Mortgaged
     Properties, all before the Rents are applied by Assignor for any other
     purpose; provided, however, that Assignor shall not receive from any Lessee
     more than one (1) month's rental (but excluding security deposits) in
     advance of the accrual of such rental.

          B.  1.  Upon receipt by Assignor from Assignee of notice of the
          occurrence of a Default and that Rents shall be paid directly to
          Assignee, Assignor is directed to pay directly to Assignee all Rents
          thereafter accruing.  Rents so received by Assignee shall be applied
          by Assignee, at its option, in any order determined by Assignee, in
          its sole and unreviewable discretion, notwithstanding any
          instructions, directions or requests from Assignor to the contrary, to
          (a) the payment and performance of the Notes and the remaining
          Obligation, and/or (b) expenses of and charges with respect to the
          ownership, maintenance, and operation of the Mortgaged Properties (and
          including, at Assignee's option, the maintenance, without interest
          thereon, of one or more reserves for replacements, taxes and/or
          insurance), all before the Rents are applied for any other purpose not
          inconsistent with the Loan Documents.

          2. Upon receipt by Assignor, any manager of the Mortgaged Properties
          and/or any Lessee from Assignee of notice of the occurrence of a
          Default and that Rents shall be paid directly to Assignee, Assignor,
          such manager and/or any Lessee that receives notice of the occurrence
          of a Default are hereby authorized and directed to pay directly to
          Assignee all Rents thereafter accruing, and the receipt of Rents by
          Assignee shall be a release of each such manager and Lessee to the
          extent of all amounts so paid. Rents so received by Assignee shall be
          applied by Assignee, at its option, in any order determined by
          Assignee, in its sole and unreviewable discretion, notwithstanding any
          instructions, directions or requests from Assignor or any manager or
          Lessee to the contrary, to (a) the payment and performance of the
          Notes and the remaining Obligation, and/or (b) expenses of and charges
          with respect to the ownership, maintenance and operation of the
          Mortgaged Properties (and including, at Assignee's option, the
          maintenance, without interest thereon, of one or more reserves for
          replacements, taxes and/or insurance), all before the Rents are
          applied for any other purpose not inconsistent with the Loan
          Documents.

          3. Following satisfaction of the Obligation, this Assignment shall
          terminate, and all Rents shall be paid to Assignor as its interests
          may appear in the Leases.

                  ARTICLE II:  REPRESENTATIONS AND WARRANTIES

     To induce Assignee to loan funds, the obligation for the repayment of which
is evidenced by the Notes and the Credit Agreement, Assignor does hereby
represent and warrant to Assignee that the representations and warranties set
forth in Section 3.2 of the Deed of Trust are true and correct.

                      ARTICLE III:  ASSIGNOR'S COVENANTS

     So long as this assignment remains in effect, Assignor covenants and agrees
that (unless Assignee shall otherwise consent in writing) Assignor shall comply
with the covenants and agreements of Assignor in Section 3.2 of the Deed of
Trust.

                        ARTICLE IV:  ASSIGNEE'S RIGHTS

4.1  Upon or at any time after the occurrence and during the continuance of a
Default, Assignee, at its option, without notice and without regard to the
adequacy of any security for the Obligation, shall have the right, power, and
authority, at its option, to exercise and enforce any or all of the following
rights and remedies:

          A.  To terminate the right granted in SECTION 1.2.A. hereof to
     Assignor to collect the Rents as aforesaid, and require that Assignor, the
     manager of the Mortgaged Properties and/or Lessees pay Rents to Assignee by
     giving notice as provided in SECTION 1.2.B., and, without taking
     possession, in Assignee's own name, to demand, collect, receive, sue for,
     attach, and levy upon the Rents, to give proper receipts, releases, and
     acquittances therefor and, after deducting all necessary and reasonable
     expenses of collection, including reasonable attorneys' fees, to apply the
     net proceeds thereof, together with any funds of Assignor deposited with
     Assignee, as provided in SECTION 1.2.B.;

          B. To exercise all of the rights and remedies provided for in the
     Notes, the Deed of Trust, the Credit Agreement, this Assignment, or any
     other instrument or document evidencing or securing the Notes or executed
     in connection therewith;

Page 1
<PAGE>
 
          C.  Without regard to the adequacy of the Rents, with or without any
     action or proceeding, through any person or by any agent, or by the
     trustee(s) designated in the Deed of Trust, or by a receiver to be
     appointed by court, and irrespective of Assignor's possession, to enter
     upon, take possession of, manage, and operate the Mortgaged Properties, or
     any part thereof, to make,  modify, enforce, cancel, or accept the
     surrender of any Lease, to remove and evict any lessee, to increase or
     reduce Rents, to decorate, to clean, and to make repairs, and to otherwise
     do any act or incur any costs or expenses that Assignee shall deem proper
     to collect the Rents assigned hereunder, as fully and to the same extent as
     Assignor could do if in possession, and in such event to apply any funds so
     collected to (i) the ownership, maintenance and operation of the Mortgaged
     Properties (and including, at Assignee's option, the maintenance, without
     interest thereon, of one or more reserves for replacements, taxes, and/or
     insurance), but in such order as Assignee shall deem proper, including
     payment of reasonable management, brokerage, and attorneys' fees, and (ii)
     the payment of the Obligation (as Assignee may in its sole discretion
     determine).

4.2  Neither the collection of the Rents and application thereof, nor the entry
upon and taking possession of the Mortgaged Properties as contemplated in this
ARTICLE shall cure or waive any default, waive, modify, or affect any notice of
default given by Assignor to Assignee in accordance with the terms of this
Assignment, the Credit Agreement, the Notes or any other Loan Document or
invalidate any act done pursuant to such notice, and the enforcement of such
right or remedy by Assignee, once exercised, shall continue for so long as
Assignee shall elect, notwithstanding that its collection of the Rents may have
cured for a time the original Default.  If, after exercising rights under this
ARTICLE, Assignee shall thereafter elect to discontinue the exercise of such
right or remedy, the same or any other right or remedy under this ARTICLE may be
reasserted at any time and from time-to-time following any subsequent Default.

4.3  None of the rights or remedies of the Assignee under any of the Loan
Documents shall be delayed or in any way prejudiced by virtue of this
Assignment, and this Assignment is intended to be cumulative of and in addition
to all other rights and remedies granted to the Assignee.

                           ARTICLE V:  MISCELLANEOUS

5.1.  Notwithstanding any provision in this Assignment to the contrary, upon
full payment and satisfaction of the Obligation, this Assignment shall
terminate, but the affidavit, certificate, letter or statement of any officer or
agent of Assignee stating that any part of the Obligation remains unpaid or
undischarged shall constitute conclusive evidence of the validity, effectiveness
or continuing force of this Assignment, and any person, firm or corporation may,
and is hereby authorized to, rely thereon.  Written demand made by Assignee
delivered to the manager of the Mortgaged Properties and/or any Lessee for
payment of Rents by reason of the occurrence of any Default claimed by Assignee
shall be sufficient evidence of each such manager's and such Lessee's obligation
and authority to make all future payments of Rents to Assignee without the
necessity for further consent by the Assignor.  Assignor hereby indemnifies and
agrees to hold each such manager and Lessee free and harmless from and against
all liability, loss, cost, damage or expense suffered or incurred by such
manager or Lessee by reason of its compliance with any demand for payment of
Rents made by the Assignee contemplated by the preceding sentence.

5.2.  If Assignee receives any Rents as provided in this Assignment, then the
provisions of SECTION 6.11 of the Deed of Trust shall apply to the Rents
received by Assignee.

5.3.  The Assignee shall not be liable for any loss sustained by the Assignor
resulting from the Assignee's failure to let the Mortgaged Properties after the
occurrence of a Default, or from any other act 

Page 1
<PAGE>
 
or omission of the Assignee in managing the Mortgaged Properties after the
occurrence of a Default, unless such loss is caused by the willful misconduct,
gross negligence, or bad faith of the Assignee. Nor shall the Assignee be
obligated to perform or discharge nor does the Assignee hereby undertake to
perform or discharge any obligation, duty, or liability under the Leases or
under or by reason of this Assignment and the Assignor shall, and does hereby
agree to, indemnify the Assignee for, and to hold the Assignee harmless from,
any and all liability, loss, or damage which may or might be incurred under the
Leases or under or by reason of this Assignment, and from any and all claims and
demands whatsoever which may be asserted against the Assignee by reason of any
alleged obligations or undertakings on its part to perform or discharge any of
the terms, covenants, or agreements contained in the Leases, except for the
willful misconduct, gross negligence, or bad faith of Assignee. Should the
Assignee incur any such liability under the Leases or under or by reason of this
Assignment or in defense of any such claims or demands, the amount thereof,
including costs, expenses, and reasonable attorneys' fees shall constitute a
portion of the Obligation. And it is further understood that this Assignment
shall not operate to place responsibility for the control, care, management, or
repair of the Mortgaged Properties upon the Assignee, nor for the carrying out
of any of the terms and conditions of the Leases; nor shall it operate to make
the Assignee responsible or liable for any waste committed on the Mortgaged
Properties by the Lessees or any other parties, or for any dangerous or
defective condition of the Mortgaged Properties, or for any negligence (except
for gross negligence or willful misconduct of Assignee) in the management,
upkeep, repair, or control of the Mortgaged Properties resulting in loss,
injury, or death to any lessee, licensee, employee, or stranger. ASSIGNOR
ACKNOWLEDGES AND CONFIRMS THAT ITS OBLIGATIONS AND INDEMNITEES UNDER THIS
SECTION 5.3. INCLUDE ANY CLAIMS RESULTING FROM THE NEGLIGENCE OR ALLEGED
NEGLIGENCE OF ASSIGNEE.

5.4.  Assignee shall not be liable for Assignee's failure to collect, or its
failure to exercise diligence in the collection of, Rents, but shall be
accountable only for Rents that it shall actually receive.

5.5.  As between Assignee and Assignor and any person claiming through or under
Assignor, this Assignment is intended to be absolute, unconditional and
presently effective, and the provisions of SECTIONS 1.2.B. and 4.1.A. regarding
notice of default by Assignee to the manager of the Mortgaged Properties and/or
Lessees are intended solely for the benefit of such Persons and shall never
inure to the benefit of Assignor or any person claiming through or under
Assignor, other than a manager or Lessee who has not received a notice of
default.

5.6.  It shall never be necessary for Assignee to institute legal proceedings of
any kind whatsoever to enforce the provisions of this Assignment regarding
collecting Rents.

5.7.  This Assignment shall be governed by and construed under the laws of the
State of Texas.

Each of the Lenders

Ladies and Gentlemen:

   We have acted as counsel to Prentiss Properties Acquisition Partners, L.P., a
Delaware limited partnership ("BORROWER") [and ________________, a
_________________ ("GRANTOR")] in connection with a $100,000,000.00 credit
facility under that certain Credit Agreement dated as of October 17, 1996 (the
"CREDIT AGREEMENT"), between Borrower, Bank One, Texas, N.A., a national banking
association, as Administrative Agent for the Lenders (in such capacity, the
"ADMINISTRATIVE AGENT"), NationsBank of Texas, N.A., a national banking
association, as Documentation Agent for the Lenders, and each of the Lenders
defined therein (collectively sometimes referred to herein, together with any
successors and assigns, as the "LENDERS").

   All capitalized terms used herein shall, unless otherwise indicated, have the
same meanings assigned to such terms in the Credit Agreement.

                              DOCUMENTS REVIEWED

   In connection with rendering this opinion, we have reviewed the following
documents:
<PAGE>
 
   1.  Deed of Trust, Assignment, Security Agreement and Financing Statement
dated ____________, 199__, executed by Borrower [Grantor] to Trustee, for the
benefit of the Administrative Agent;

   2.  Assignment of Leases and Rents dated _________, 1995 from Borrower
[Grantor] in favor of the Administrative Agent; and

   3.  Financing Statements (herein so called)  executed by Borrower [Grantor],
filed in the Real Property Records of _____________ County, ________________,
and with the Office of the Secretary of State of the State of _______.

   The documents described in items 1-3 above are collectively called the
"SECURITY DOCUMENTS."  The real and personal property collateral covered by the
Security Documents are collectively called the "COLLATERAL."

                                QUALIFICATIONS

   We have assumed, with your permission: (a) the genuineness of all signatures;
(b) the conformity to authentic original documents of all documents submitted to
us as certified, conformed or photostatic copies; (c) that the execution,
delivery and performance of the Security Documents have been duly authorized by
all necessary partnership, trust, corporate, or other action on the part of each
of the parties thereto; and (d) that each of the Security Documents is a legal,
valid, and binding obligation of the parties thereto other than Borrower [or
Grantor], enforceable against such parties in accordance with their respective
terms.  We understand that, with respect to the matters described in (c), you
will be relying upon the opinion of Akin, Gump, Strauss, Hauer & Feld, L.L.P.

   We are licensed to practice law only in the State of ____________, and the
opinions expressed herein are to the laws of the State of __________ and to the
federal laws of the United States of America.

                                   OPINIONS

   Based upon the foregoing, but subject to the qualifications set forth herein,
we are of the opinion that:

   1.  The Security Documents are legal, valid and binding obligations of
Borrower [Grantor], enforceable against Borrower [Grantor] in accordance with
their respective terms, except as such enforceability may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium, or other similar
laws affecting the enforceability of creditors' rights generally and general
principles of equity and except that equity.

   2.  A _______________ court, in a case properly presented, would uphold the
Texas choice of law provisions in the Security Documents.

   3. The filing of the Financing Statements in the Office of the Secretary of
State of ___________ and the recording of the Security Documents in the Real
Property Records of the __________ County, ___________________, are the only
filings and recordings necessary to perfect the lien and security interest which
is granted by the Security Documents in the personal property Collateral
described therein that is owned by Borrower [Grantor], and located in such
county.
<PAGE>
 
   4.  Assuming that the internal laws of the State of _______ apply in all
respects to the opinions stated herein, foreclosure against all or a portion of
the Collateral located in _____________, properly structured, can be effected in
__________ without causing an extinguishment or payment of the obligations to
the Lenders evidenced by the Credit Agreement (the "SECURED OBLIGATIONS"),
except to the extent of the foreclosure bid assuming such bid complies with
_________ law.  When so properly structured, the liens and security interests
created by the Security Documents against that portion of the Collateral, if
any, that has not been subjected to foreclosure shall remain in full force and
effect to secure that portion of the Secured Obligations remaining unpaid after
such foreclosure sale and any other foreclosure sales.

   5.  Under the statutes of the State of __________, Borrower [Grantor] has
adequate power and authority to conduct its business with respect to the
Collateral in the State of ____________.

   6.  Neither the Administrative Agent, the Documentation Agent, nor the
Lenders will be subject to taxation by the State of _____________ solely by
virtue of making the loans to Borrower [Grantor], or taking liens and security
interests in the Collateral under the Security Documents.

   7.  Upon the filing thereof, there will be no recording, intangible, or
mortgage tax due and payable in connection with any of the Security Documents,
other than nominal filing fees.

   8.  The Security Documents are in recordable form in the State of ________.

   9.  Neither the making of the loans pursuant to the Credit Agreement, nor the
execution, delivery and recording of the Security Documents, shall require that
the Administrative Agent, the Documentation Agent  or any Lender qualify as a
foreign corporation to conduct business in the State of _______________.

                            Sincerely,

     During such period, the Syndicating Lenders shall (i) not solicit or enter
     into any such assignment or participation except as provided in this
     SECTION 13.11(e), and (ii) refer each prospective Purchaser or Participant
     that expresses an interest in purchasing or acquiring any such assignment
     or participation to the other Syndicating Lender.  Each Syndicating Lender,
     upon identifying any prospective Purchaser or Participant desiring to be an
     assignee of or participant in any portion of the Rights and obligations of
     the Syndicating Lenders under this Agreement, shall deliver written notice
     to the other Syndicating Lender of the terms of such transaction ("PROPOSED
     SYNDICATION TRANSACTION").  Each Syndicating Lender shall have the right to
     participate in such Proposed Syndication Transaction on the terms set forth
     in such notice by so notifying the other Syndicating Lender within five (5)
     days of receiving such notice.  The assignment or participation effected by
     such Proposed Syndication Transaction shall be allotted equally to each
     participating Syndicating Lender.  Notwithstanding anything contained to
     the contrary in SECTION 13.11(c), the aggregate assignments to a Purchaser
     by the Syndicating Lenders shall be in an aggregate amount of not less
     $15,000,000.00 or a greater integral multiple of $1,000,000.00.

                        continuing as of the Defeasance Date other than a Non-
                        Curable Property Default with respect to an Individual
                        Property to be released from the Lien of the related

                        Defeasance Deposit for the Defeasance Event;

                        of the Defeasance Event, Borrower shall prepare all
                        necessary documents to amend and restate the Note and
                        issue two substitute notes, one note having a principal

                 (vii)  Borrower shall execute and deliver a security agreement,
                        in form and substance reasonably satisfactory to Lender,
                        creating a first priority lien on the Defeasance Deposit

                        Obligations and all obligations, rights and duties under

                        the Successor Borrower, that Lender has a perfected
                        first priority security interest in the Defeasance
                        Deposit and the U.S. Obligations delivered by Borrower,
                        and that any REMIC Trust formed pursuant to a
                        Securitization will not fail to maintain its status as a
                        "real estate mortgage investment conduit" within the
                        meaning of Section 860D of the Code as a result of such

                        applicable Rating Agencies to the effect that the
                        Defeasance Event and any related release of any of the
                        Individual Properties pursuant to Section 2.4 will not
                        in and of itself result in a withdrawal, qualification
                        or downgrade of the respective ratings in effect
                        immediately prior to such Defeasance Event for the
                        Securities issued in connection with the Securitization
                        which are then outstanding. If required by the

                        deliver or cause to be delivered a non-consolidation
                        opinion with respect to the Successor Borrower in

                        release of one or more Liens as provided in Section 2.4

appoints Lender as its agent and attorney-in-fact for the purpose of using the
Defeasance Deposit to purchase U.S. Obligations which provide payments on or
prior to, but as close as possible to, all successive scheduled payment dates
after the Defeasance Date upon which payments are required under this Agreement
and the Note (in the case of a Defeasance Event for the entire outstanding
principal balance of the Loan) or the Defeased Note (in the case of a Defeasance
Event for only a portion of the outstanding principal balance of the Loan)
assuming Borrower repays the Note in full on the Anticipated Repayment Date (the
"SCHEDULED DEFEASANCE PAYMENTS").  Borrower, pursuant to the Security Agreement

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

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

                 (b) In the event that, after the Anticipated Repayment Date,
the Borrower must incur an extraordinary operating expense or capital expense
not set forth in the Annual Budget (each an "EXTRAORDINARY EXPENSE"), then the
                                             ---------------------            
Borrower shall promptly deliver to Lender a reasonably detailed explanation of
such proposed Extraordinary Expense for the Lender's approval.

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

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

a "SUBSTITUTE PROPERTY" and collectively, the "SUBSTITUTE PROPERTIES"), provided
   -------------------                         ---------------------
that (a) the Substitution Conditions are satisfied with respect to Substitute
Properties other than a Substituted Property damaged by a casualty or affected
by a condemnation or eminent domain proceeding and for which Net Proceeds have
not been made available by Lender to Borrower for Restoration pursuant to the
terms and provisions of Section 7.1.3, (b) no such substitution may occur after
                        -------------
the Anticipated Repayment Date and (c) such substitution shall not be allowed
more than three (3) times during the term of the Loan. In addition, any such
substitution shall be subject, in each case, to the satisfaction of the
following conditions precedent:

          (i)    Lender shall have received a copy of a deed or an assignment
                 and assumption of lessee's interest in the Ground Lease
                 (together with the ground lessor's consent thereto), as
                 applicable, conveying all of Borrower's right, title and
                 interest in and to the Substituted Property to an entity other
                 than Borrower and a letter from Borrower countersigned by a
                 title insurance company acknowledging receipt of such deed or
                 assignment and assumption, as applicable, and agreeing to
                 record such deed or assignment and assumption, as applicable,
                 in the real estate records for the county in which the
                 Substituted Property is located.

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

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

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

                                      -25-
<PAGE>
 
                 may be determined from the information regarding such Net
                 Operating Income available.

          (v)    The Net Operating Income and Debt Service Coverage Ratio (for
                 the twelve (12) month period immediately preceding the
                 substitution) for the Substitute Property is greater than one
                 hundred twenty-five percent (125%) of the Net Operating Income
                 and Debt Service Coverage Ratio (for the twelve (12) month
                 period immediately preceding the substitution) for the related
                 Substituted Property. For purposes of this clause (v), the Debt
                 Service Coverage Ratio with respect to a Substitute Property or
                 a Substituted Property shall be calculated using the Net
                 Operating Income with respect to such Substitute Property or
                 the Substituted Property, as applicable, and the principal and
                 interest due and payable on the Note with respect to the
                 related Pro rata Substitute Release Amount or Pro rata Release
                 Amount, as applicable.

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

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

          (viii) Borrower shall have executed, acknowledged and delivered to
                 Lender (A) a Mortgage, an Assignment of Leases and two UCC
                 Financing Statements with respect to the Substitute Property,
                 together with a letter from Borrower countersigned by a title
                 insurance company acknowledging receipt of such Mortgage,

                 Assignment of Leases and UCC-1 Financing Statements and
                 agreeing to record or file, as applicable, such Mortgage,
                 Assignment of Leases and Rents and one of the UCC-1 Financing
                 Statements in the real estate records for the county in which
                 the Substitute Property is located and to file one of the UCC-1
                 Financing Statement in the office of the Secretary of State of
                 the state in which the Substitute Property is located, so as to
                 effectively create upon such recording and filing valid and
                 enforceable Liens upon the Substitute Property, of the
                 requisite priority, in favor of Lender (or such other trustee
                 as may be desired under local law), subject only to the
                 Permitted Encumbrances and such other Liens as are permitted

                 Agreements and an Environmental Indemnity with respect to the
                 Substitute Property. The Mortgage, Assignment of Leases, UCC-1

                 same in form and substance as the counterparts of such
                 documents executed and delivered with respect to the related
                 Substituted Property subject to modifications reflecting the
                 Substitute Property as the Individual Property that is the
                 subject of such documents and such modifications reflecting the
                 laws of the state in which the Substitute Property is located
                 as shall be recommended by the counsel admitted to practice in
                 such state and delivering the opinion as to the enforceability

                 Mortgage encumbering the Substitute Property shall secure all
                 amounts evidenced by the Note, provided that in the event that
                 the jurisdiction in which the Substitute Property is located
                 imposes a mortgage recording, intangibles or similar tax and
                 does not permit the allocation of indebtedness for the purpose
                 of determining the amount of such tax payable, the principal
                 amount secured by such Mortgage shall be equal to one hundred
                 fifty percent (150%) of the amount of the Loan allocated to the
                 Substitute Property. The amount of the Loan allocated to the
                 Substitute Property (such amount being hereinafter referred to
                 as the "SUBSTITUTE RELEASE AMOUNT") shall the Release Amount of
                         -------------------------

                 endorsement to each Title Insurance Policy insuring the Lien of
                 an existing Mortgage as of the date of the substitution
                 available with respect to the Title Insurance Policy insuring
                 the Lien of the Mortgage with respect to the Substitute
                 Property and (B) a Title Insurance Policy (or a marked, signed

                 substitution, with reinsurance and direct access agreements
                 that replace such agreements issued in connection with the
                 Title Insurance Policy insuring the Lien of the Mortgage
                 encumbering the Substituted Property. The Title Insurance
                 Policy issued with respect to the Substitute Property shall (1)
                 provide coverage in the amount of the Substitute Release Amount
                 if the "tie-in" or similar endorsement described above is
                 available or, if such endorsement is not available, in an
                 amount equal to one hundred fifty percent (150%) of the
                 Substitute Release Amount, (2) insure Lender that the relevant
                 Mortgage creates a valid first lien on the Substitute Property

                 exceptions and exclusions from coverage (as modified by the
                 terms of any endorsements), (3) contain such endorsements and
                 affirmative coverages as are contained in the Title Insurance

                 and their successors and assigns, in the same form and having
                 the same content as the certification of the Survey of the
                 Substituted Property prepared by a professional land surveyor
                 licensed in the state in which the Substitute Property is
                 located and acceptable to the Rating Agencies in accordance
                 with the 1992 Minimum Standard Detail Requirements for
                 ALTA/ACSM Land Title Surveys. Such survey shall reflect the
                 same legal description contained in the Title Insurance Policy
                 relating to such Substitute Property and shall include, among
                 other things, a metes and bounds description of the real
                 property comprising part of such Substitute Property. The
                 surveyor's seal shall be affixed to each survey and each survey
                 shall certify that the surveyed property is not located in a
                 "one-hundred-year flood hazard area."

          (xii)  Lender shall have received valid certificates of insurance
                 indicating that the requirements for the policies of insurance

                 Property does not contain any Hazardous Substance (as defined
                 in the Mortgage) and is not subject to any risk of
                 contamination from any off-site Hazardous Substance. If any
                 such report discloses the presence of any Hazardous Substance
                 or the risk of contamination from any off-site Hazardous
                 Substance, such report shall include an estimate of the cost of
                 any related remediation and Borrower shall deposit with Lender
                 an amount equal to one hundred fifty percent (150%) of such
                 estimated cost, which deposit shall constitute additional
                 security for the Loan and shall be released to Borrower upon
                 the delivery to Lender of (A) an update to such report
                 indicating that there is no longer any Hazardous Substance on
                 the Substitute Property or any danger of contamination from any
                 off-site Hazardous Substance that has not been fully remediated
                 and (B) paid receipts indicating that the costs of all such
                 remediation work have been paid.

          (xiv)  Borrower shall deliver or cause to be delivered to Lender (A)
                 updates certified by Borrower of all organizational

                 Advance; (B) good standing certificates, certificates of
                 qualification to do business in the jurisdiction in which the
                 Substitute Property is located (if required in such

                 Borrower authorizing the substitution and any actions taken in
                 connection with such substitution.

          (xv)   Lender shall have received the following opinions of Borrower's
                 counsel: (A) an opinion or opinions of counsel admitted to

                 Property is located stating that the Loan Documents delivered
                 with respect to the Substitute Property pursuant to clause
                 (viii) above are valid and enforceable in accordance with their
                 terms, subject to the laws applicable to creditors' rights and
                 equitable principles, and that Borrower is qualified to do
                 business and in good standing under the laws of the
                 jurisdiction where the Substitute Property is located or that
                 Borrower is not required by applicable law to qualify to do

                 delivery of such Loan Documents and the performance by Borrower
                 of its obligations thereunder will not cause a breach of, or a
                 default under, any agreement, document or instrument to which

                 the ability of Lender to enforce its remedies under all of the
                 Loan Documents or to realize the benefits of the cross-
                 collateralization provided for thereunder; (D) an update of the

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

indebtedness, secured or unsecured, direct or indirect, absolute or contingent

does not exceed an amount equal to five percent (5%) of the outstanding
principal amount of the Loan at any time, (ii) the proceeds of which are not
distributed to Borrower or any direct beneficial owner of an interest in
Borrower, but are instead used to fund directly the costs of items described

agreement having terms (other than the interest rate and repayment terms) no
less favorable to Borrower than the terms of the Loan, (iv) the terms of which
shall require that the principal amount of such indebtedness be repaid from Net
Operating Income prior to any distributions to any direct beneficial owner of an
interest in Borrower (other than for income, franchise, or other taxes imposed
on Borrower for the privilege of doing business in the jurisdictions in which
the Property is located) and (v) is subject to a subordination and standstill
agreement satisfactory in form and substance to Lender. Except as set forth in
the immediately preceding sentence, no indebtedness other than the Debt may be

                        ---- -----
               (v) Borrower has not made and will not make any loans or advances

Mortgage.

               (vii) Borrower has done or caused to be done and will do all
things necessary to observe partnership formalities and preserve its existence,

shall correct any known misunderstanding regarding its status as a separate

of its Affiliates as a division or unit of the other and shall maintain and
utilize separate stationery, invoices and checks; provided, however that
Borrower may use the word "Prentiss" as a part of Borrower's name, may describe

Partners, L.P. so long as such description is true and correct and may permit
its relationship with its Affiliates to be disclosed in order to comply with any
public filing requirements applicable to Prentiss Properties Trust.

               (x) Borrower is adequately capitalized and will maintain adequate
capital for the normal obligations reasonably foreseeable in a business of its

For purposes of this clause (xii), funds distributed to partners of Borrower as
permitted under this Agreement shall no longer constitute funds of Borrower.

responsible for the debts or obligations of any other Person.

               (xv) If Borrower is a limited partnership, the general partner is

partner of Borrower reasonably satisfactory to Lender who shall not have been at
the time of each such individual's appointment, and may not have been at any
time during the preceding five (5) years (A) a shareholder of, or an officer,
director, partner or employee of, Borrower or any of its shareholders,

derives more than ten percent (10%) of its revenues from its activities with
Borrower or its Affiliates, (C) a Person controlling or under common control
with any such shareholder, partner supplier or customer, or (D) a member of the
immediate family of any such shareholder, officer, director, partner, employee,
supplier or customer of any other director of Borrower. As used herein, the term
"control" means the possession, directly or indirectly, of the power to direct
or cause the direction of the management and policies of a Person, whether
through ownership of voting securities, by contract or otherwise.

               (xvii) Borrower shall not cause or permit the board of directors
of the general partner of Borrower to take any action which, under the terms of
any certificate of incorporation, by-laws or any voting trust agreement with
respect to any common stock, requires a vote of the board of directors of the
general partner of Borrower unless at the time of such action there shall be at
least one (1) member who is an Independent Director.

               (xviii) Borrower shall conduct its business so that the
assumptions made with respect to Borrower in that certain opinion letter dated
the date hereof (the "INSOLVENCY OPINION") delivered by Akin, Gump, Strauss,

Hauer & Feld in connection with the Loan shall be true and correct in all
respects.

          (ff) No Change in Facts or Circumstances; Disclosure.  All information
               -----------------------------------------------                  
submitted by Borrower to Lender and in all financial statements, rent rolls,
reports, certificates and other documents submitted in connection with the Loan
or in satisfaction of the terms thereof and all statements of fact made by
Borrower in this Agreement or in any other Loan Document, are accurate, complete
and correct in all material respects to the best of Borrower's knowledge.  To
the best of Borrower's knowledge, there has been no material adverse change in
any condition, fact, circumstance or event that would make any such information
inaccurate, incomplete or otherwise misleading in any material respect or that
otherwise materially and adversely affects or might materially and adversely
affect any of the Properties or the business operations or the financial
condition of Borrower.  To the best of Borrower's knowledge, Borrower has
disclosed to Lender all material facts and has not failed to disclose any
material fact that could cause any representation or warranty made herein to be
materially misleading.

          (gg) Illegal Activity.  No portion of any Individual Property has been
               ----------------                                                 
or will be purchased with proceeds of any illegal activity.

          (hh) Ground Lease.  Borrower hereby represents and warrants to Lender
               ------------                                                    
the following with respect to the Ground Lease:

               (i) RECORDING; MODIFICATION. The Ground Lease has been duly
recorded, the Ground Lease permits the interest of the Borrower to be encumbered
by a 

                                      -53-
<PAGE>
 
mortgage, the landlord under the Ground Lease (the "LANDLORD") has approved
                                                    -------- 
and consented to the encumbrance of the Individual Property by the applicable
Mortgage and a complete and correct description of the Ground Lease, including
all amendments, modifications or supplements thereto, is set forth in the
definition thereof contained in Section 1.1.  The Ground Lease may not be
                                -----------                              
canceled, terminated, surrendered or amended without the prior written consent
of Lender.

               (ii) NO LIENS. Except for the Permitted Encumbrances, the
Borrower's interest in the Ground Lease is not subject to any liens or
encumbrances superior to, or of equal priority with, the Mortgage other than the
Landlord's related fee interest.

               (iii) GROUND LEASE ASSIGNABLE. The Borrower's interest in the
Ground Lease is assignable to the Lender, and by Lender and its successors and
assigns, upon notice to, but without the consent of, the Landlord (or, if any
such consent is required, it has been obtained prior to the Closing Date).

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

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

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

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

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

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

Borrower set forth in Section 4.1 and elsewhere in this Agreement and in the
                      -----------                                           
other Loan Documents shall survive for so long as the context thereof requires
but at least as long as any amount remains owing to Lender under this Agreement
or any of the other Loan Documents by Borrower, provided that the accuracy of
such representations and warranties shall be determined as of the Closing Date
or a Subsequent Advance Date, as applicable.  All representations, warranties,
covenants and agreements made in this Agreement or in the other Loan Documents
by Borrower shall be deemed to have been relied upon by Lender notwithstanding
any investigation heretofore or hereafter made by Lender or on its behalf.

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

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

protect all of its material property used in the conduct of its business and
shall keep all of the Properties in good working order and repair (except for
ordinary wear and tear and damage from a casualty or condemnation pending any
required restoration thereof), and from time to time make, or cause to be made,
all reasonably necessary repairs, renewals, replacements, betterments and
improvements thereto, all as more fully provided in the Mortgages encumbering
such Properties.  Borrower shall keep each of the Properties insured at all
times by financially sound and reputable insurers, to such extent and against
such risks, and maintain liability and such other insurance, as is more fully
provided in this Agreement.

              -----------------------                                         
Charges now or hereafter levied or assessed or imposed against the Properties or
any part thereof prior to delinquency or the imposition of any fine or penalty;
provided, however, Borrower's obligation to directly pay Taxes shall be
suspended for so long as Borrower complies with the terms and provisions of

paid and discharged any lien or charge whatsoever which may be or become a lien
or charge against any of the Properties (subject to Borrower's right to contest
Taxes and Other Charges in accordance with this Section 5.1(b)), and shall
                                                ---------------           
promptly pay for all utility services provided to the Properties.  Borrower
shall furnish to Lender receipts for 

                                      -55-

the payment of the Taxes and the Other Charges prior to the date the same shall
become delinquent (provided, however, that Borrower is not required to furnish

by Lender pursuant to Section 7.3 hereof). After prior written notice to Lender,
                      -----------
Borrower, at its own expense, may contest by appropriate legal proceeding,
promptly initiated and conducted in good faith and with due diligence, the
amount or validity or application in whole or in part of any Taxes or Other
Charges, provided that (i) no Event of Default has occurred and remains uncured,
(ii) Borrower is permitted to do so under the provisions of any mortgage or deed
of trust affecting any of the Properties, (iii) such proceeding shall be
permitted under and be conducted in accordance with the provisions of any other
instrument to which Borrower is subject and shall not constitute a default
thereunder and such proceeding shall be conducted in accordance with all
applicable statutes, laws and ordinances, (iv) no Individual Property nor any
part thereof or interest therein will be in danger of being sold, forfeited,
terminated, canceled or lost, and (v) Borrower shall promptly upon final
determination thereof pay the amount of any such Taxes or Other Charges,

connection therewith. In addition, if the Taxes or Other Charges are not paid in
full when the Borrower commences such contest, then the following shall apply:
(A) such proceeding shall suspend the collection of Taxes or Other Charges from
the applicable Individual Property, and (B) Borrower shall have furnished such
security as may be required in the proceeding, or as may be reasonably requested
by Lender or sufficient funds are on deposit in the Tax and Insurance Escrow
Fund to pay any such Taxes or Other Charges pursuant to Section 7.3, to insure
                                                        -----------
the payment of any such Taxes or Other Charges, together with all interest and
penalties thereon. Lender may pay over any such cash deposit or part thereof
held by Lender to the claimant entitled thereto at any time when, in the
reasonable judgment of Lender, the entitlement of such claimant is established
after Borrower's appeals have been exhausted.

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

the other Loan Documents) any of the Properties or any part thereof at
reasonable hours upon reasonable advance notice subject to the rights of
tenants, subtenants and licensees with respect to the Properties.

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

          (f) Cooperate in Legal Proceedings.  Borrower shall cooperate fully
              ------------------------------

hereunder or any rights obtained by Lender under any of the other Loan Documents
and, in connection therewith, permit Lender, at its election and at its cost, to

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

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

                                      -60-

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

confirmation in writing from the applicable Rating Agencies that the replacement
of Manager with an Affiliate of Manager will not, in and of 

                                      -61-

Lender, create, incur, assume or suffer to exist any Lien on any portion of any
of the Properties or permit any such action to be taken, except:

material change in the scope or nature of its business objectives, purposes or
operations, or undertake or participate in activities other than the continuance
of its present business.

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

party to, any transaction with an Affiliate of Borrower or any of the partners
of Borrower except in the ordinary course of business and on terms which are
fully disclosed to Lender in advance and are no less favorable to Borrower or
such Affiliate than would be obtained in a comparable arm's-length transaction
with an unrelated third party.

          (g) Zoning.  Borrower shall not initiate or consent to any zoning
              ------                                                       
reclassification of any portion of any of the Properties or seek any variance
under any existing zoning ordinance or use or permit the use of any portion of
any of the Properties in any manner that could result in such use becoming a

become a nonconforming use, Borrower shall not cause or permit the nonconforming
use to be discontinued or abandoned without the prior written consent of Lender,

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

contributing mortgagee clause in favor of Lender providing that the loss
thereunder shall be payable to Lender.

          (e) All Policies of insurance provided for in Section 7.1.1(a)(v)

Borrower, or of any tenant under any Lease or other occupant, or failure to

related Insurance Premium, which might otherwise result in a forfeiture of the
insurance or any part thereof, shall in any way affect the validity or
enforceability of the insurance insofar as Lender is concerned;

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

all insurance required hereunder is in full force and effect, Lender shall have
the right, without notice to Borrower, to take such action as Lender deems
necessary to protect its interest in the Property, including, without
limitation, the obtaining of such insurance coverage as Lender in its reasonable
discretion deems necessary to satisfy the requirements of Section 7.1.1(a), and

all premiums incurred by Lender in connection with such action or in obtaining
such insurance and keeping it in effect shall be paid by Borrower to Lender upon
demand and until paid shall be secured by the Mortgages and shall bear interest
at the Default Rate.

          (g) If the Individual Property shall be damaged or destroyed, in whole
or in part, by fire or other casualty, Borrower shall give prompt notice of such
damage to Lender and shall promptly commence and diligently prosecute the
completion of the repair and restoration of the Individual Property as nearly as
possible to the condition the Individual Property was in immediately prior to
such fire or other casualty, with such alterations as may be reasonably approved
by Lender (a "RESTORATION") and otherwise in accordance with Section 7.1.3.

Borrower shall pay all costs of such Restoration whether or not such costs are
covered by insurance.  Lender may, but shall not be obligated to make proof of
loss if not made promptly by Borrower;

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

(including but not limited to any transfer made in lieu of or in anticipation of
the exercise of such taking), Borrower shall continue to pay the Debt at the
time and in the manner provided for its payment in the Note and in this
Agreement and the Debt shall not be reduced until any award or payment therefor

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

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

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

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

                                      -71-

          disbursement of the Net Proceeds, and until so disbursed pursuant

          Debt and other obligations under the Loan Documents.

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

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

          7.3.1  TAX AND INSURANCE ESCROW FUND.  Borrower shall pay to Lender on

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

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

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

                                      -73-

Tax and Insurance Escrow Fund or permit any lien or encumbrance to attach
thereto, or any levy to be made thereon, or any UCC-1 Financing Statements,
except those naming Lender as the secured party, to be filed with respect
thereto.

                 --------------------------------------------                 
or applied as above provided, any amounts in the Tax and Insurance Escrow Fund
shall constitute additional security for the Debt.  Upon the occurrence of an
Event of Default, Lender may apply any sums then present in the Tax and
Insurance Escrow Fund to the payment of the following items in any order in its
sole discretion: (i) Taxes and Other Charges; (ii) insurance premiums; (iii)
interest on the unpaid principal balance of the Note; (iv) amortization of the
unpaid principal balance of the Note; or (v) all other sums payable pursuant to
this Agreement and the other Loan Documents.

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

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

                                      -74-

necessary in its reasonable discretion based on any increases in the rent due
under the Ground Lease.

any material respect as of the date the representation or warranty was made;
provided, however, that in the case of any such representation or warranty that
is susceptible of cure, if such representation or warranty shall remain uncured

herein which specifically contains a notice requirement or grace period, if
Borrower shall be in default under such term, covenant or condition after the
giving of such notice or the expiration of such grace period;

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

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

              (xiii) if a default on the part of Borrower shall have occurred

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

              (xv) if there shall be default under any of the other Loan
Documents beyond any applicable cure periods contained in such documents,

shall occur or condition shall exist, if the 

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

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

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

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

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

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

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

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

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

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

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

          IX.  SPECIAL PROVISIONS
               ------------------

          SECTION 9.1  SALE OF NOTES AND SECURITIZATION.
                       -------------------------------- 

          Lender shall have the right to sell, assign or otherwise transfer the
Loan or any portion thereof or interest therein held by Lender without the
consent of Borrower or the satisfaction of any other requirement with respect to
Borrower.  At the request of the holder of the Note and, to the extent not
already required to be provided by Borrower under this Agreement, Borrower shall
use reasonable efforts to satisfy the market standards to which the holder of
the Note customarily adheres or which may be reasonably required in the
marketplace or by the Rating Agencies in connection with the sale of the Note or
participation therein or the first successful public or private securitization
(such sale and/or securitization, the "SECURITIZATION") of rated single or
                                       --------------                     
multi-class securities (the "SECURITIES") secured by or evidencing ownership
                             ----------                                     
interests in the Note and the Mortgages, including, without limitation, to:

          (a)  (i)  provide such financial and other information with respect to
               the Properties, the Borrower and the Manager, (ii) provide
               budgets relating to the Properties and (iii) to permit to be
               performed or permitted such site inspection, appraisals, market
               studies, environmental reviews and reports (Phase I reports and,
               if appropriate, Phase II reports), engineering reports and other
               due diligence investigations of the Properties, as may be
               reasonably requested by the holder of the Note or the Rating
               Agencies or as may be reasonably necessary or appropriate in
               connection with the Securitization (the "PROVIDED INFORMATION"),
                                                        --------------------   
               together, if customary, with appropriate verification of and/or
               consents to the use of the Provided Information through letters
               of auditors or opinions of counsel of independent attorneys
               reasonably acceptable to the Lender and acceptable to the Rating
               Agencies; provided, however, that Phase II reports and other
               invasive testing may not be performed at any of the Properties
               until Borrower has received reasonably appropriate
               indemnifications and evidence of insurance from any Person
               preparing such report or performing such testing;

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

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

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

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

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

          SECTION 9.2  SECURITIZATION INDEMNIFICATION.
                       ------------------------------ 

          (a) Borrower understands that certain of the Provided Information and
the books and records delivered to Lender pursuant to Section 5.1(k) may be
                                                      --------------       
included in disclosure documents in connection with the Securitization,
including, without limitation, a prospectus or private placement memorandum
(each, a "DISCLOSURE DOCUMENT") and may also be included in filings with the
          -------------------                                               
Securities and Exchange Commission pursuant to the Securities Act of 1933, as
amended (the "SECURITIES ACT"), or the Securities and Exchange Act of 1934, as
              --------------                                                  
amended (the "EXCHANGE ACT"), or provided or made available to investors or
              ------------                                                 
prospective investors in the Securities, the Rating Agencies, and service
providers relating to the Securitization.  In the event that the Disclosure
Document is required to be revised prior to the sale of all Securities, the
Borrower will cooperate with the holder of the Note, at no cost to Borrower, in
updating the Disclosure Document by providing all current information necessary
to keep the Disclosure Document accurate and complete in all material respects.

          (b) Borrower agrees to provide in connection with each of (i) a
preliminary and a private placement memorandum or (ii) a preliminary and final
prospectus, as applicable, 

                                      -80-
<PAGE>
 
an indemnification certificate (A) certifying that Borrower has carefully
examined such memorandum or prospectus, as applicable, including without
limitation, the sections entitled "Special Considerations," "Description of the
Mortgages," "Description of the Mortgage Loans and Mortgaged Properties," "The
Manager," "The Borrower" and "Certain Legal Aspects of the Mortgage Loan," and
such sections (and any other sections reasonably requested) do not, and with
respect to any portions of such sections prepared in reliance upon the reports
of third parties, to Borrower's knowledge do not, contain any untrue statement
of a material fact or omit to state a material fact necessary in order to make
the statements made, in the light of the circumstances under which they were
made, not misleading, (B) indemnifying Lender (and for purposes of this Section
9.2, Lender hereunder shall include its officers, directors and employees), the
Affiliate of Lehman Brothers, Inc. ("LEHMAN") that has filed the registration
                                     ------
statement relating to the securitization (the "REGISTRATION STATEMENT"), each of
                                               ----------------------
its directors, each of its officers who have signed the Registration Statement
and each person or entity who controls the Affiliate within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act
(collectively, the "LEHMAN GROUP"), and Lehman, each of its directors and each
                    ------------
person who controls Lehman within the meaning of Section 15 of the Securities
Act and Section 20 of the Exchange Act (collectively, the "UNDERWRITER GROUP")
                                                           -----------------
for any losses, claims, damages or liabilities (the "LIABILITIES") to which
                                                     -----------
Lender, the Lehman Group or the Underwriter Group may become subject insofar as
the Liabilities arise out of any untrue statement or alleged untrue statement of
any material fact contained in such sections (other than any such statement made
in reliance upon the reports of third parties that do not, to Borrower's
knowledge, contain any untrue statement of a material fact or omit to state a
material fact necessary in order to make the statements made, in light of the
circumstances under which they were made, not misleading) or arise out of the
omission or alleged omission to state therein a material fact known to Borrower
and required to be stated in such sections or necessary in order to make the
statements in such sections or in light of the circumstances under which they
were made, not misleading and (C) agreeing to reimburse Lender, the Lehman Group
and the Underwriter Group for any legal or other expenses reasonably incurred by
Lender and Lehman in connection with investigating or defending the Liabilities;
provided, however, that Borrower will be liable in any such case under clauses
(B) or (C) above only to the extent that any such loss claim, damage, liability
or expense arises out of any such untrue statement or omission made therein in
reliance upon and in conformity with written information furnished to Lender by
or on behalf of Borrower expressly for use in the Disclosure Document; and
provided further, that this indemnity agreement shall not apply to any loss,
liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Borrower by
Lender, any member of the Lehman Group or any member of the Underwriter Group
expressly for use in the Disclosure Document. The foregoing indemnity with
respect to any untrue statement contained in or omission from a preliminary
private placement memorandum or preliminary prospectus shall not inure to the
benefit of any member of the Underwriting Group (or any person controlling such
member of the Underwriting Group) from whom the Person asserting any such loss,
liability, claim, damage or expense purchased any of the Securities which are
the subject thereof if the Borrower shall sustain the burden of proving that any
such loss, liability, claim, damage or expense resulted from the fact that such
Person was not sent or given a copy of the

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

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

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

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

                                      -82-
<PAGE>
 
notice from the indemnifying party to such indemnified party under the
immediately preceding sentence of this Section 9.2 and except as otherwise
                                       -----------                        
explicitly provided herein, the indemnifying party shall not be responsible for
any legal or other expenses subsequently incurred by such indemnified party in
connection with the defense thereof; provided, however, if the defendants in any
such action include both the indemnified party and the indemnifying party and
the indemnified party shall have reasonably concluded that there are any legal
defenses available to it and/or other indemnified parties that are different
from or additional to those available to the indemnifying party, the indemnified
party or parties shall have the right to select separate counsel to assert such
legal defenses and to otherwise participate in the defense of such action on
behalf of such indemnified party or parties.  The indemnifying party shall not
be liable for the expenses of more than one separate counsel unless an
indemnified party shall have reasonably concluded that there may be legal
defenses available to it that are different from or additional to those
available to another indemnified party.  In no event shall an indemnifying party
be liable to an indemnified party under this Section 9.2 for any losses, claims,
                                             -----------                        
damages or liabilities to which such indemnified party may become subject to the
extent the same arise by reason of the gross negligence, illegal acts, fraud or
willful misconduct of such indemnified party.

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

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

          SECTION 9.3  RATING SURVEILLANCE.
                       ------------------- 

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

          SECTION 9.4  EXCULPATION.
                       ----------- 

          SECTION 9.4.1  EXCULPATION.  Except as otherwise provided, Lender
                         -----------                                       
shall not enforce the liability and obligation of Borrower to perform and
observe the obligations contained in the Note, this Agreement or any other Loan
Document by any action or proceeding wherein a money judgment shall be sought
against Borrower, except that Lender may bring a foreclosure action, action for
specific performance or other appropriate action or proceeding to enable Lender
to enforce and realize upon the Mortgages or any other Loan Document, and the
interest in the Properties, the Rents and any other collateral given to Lender
created by the Loan Documents; provided, however, that any judgment in any
action or proceeding shall be enforceable against Borrower only to the extent of
Borrower's interest in the Properties, in the Rents and in any other collateral
given to Lender.  Lender, by accepting the Note and this Agreement, agrees that
it shall not, except as otherwise provided in Section 7.10 of the Mortgages, sue

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

          (b) Borrower shall indemnify, defend and hold harmless Lender from and
against any and all other liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, claims, costs, expenses and disbursements of any kind
or nature whatsoever (including, without limitation, the reasonable fees and
disbursements of counsel for Lender in connection with any investigative,
administrative or judicial proceeding commenced or threatened, whether or not
Lender shall be designated a party thereto), that may be imposed on, incurred
by, or asserted against Lender in any manner relating to or arising out of (i)
any breach by Borrower of its material obligations under, or any material
misrepresentation by Borrower contained in, this Agreement or the other Loan
Documents, or (ii) the use or intended use of the proceeds of the Loan
(collectively, the "INDEMNIFIED LIABILITIES"); provided, however, that Borrower
                    -----------------------                                    
shall not have any obligation to Lender hereunder to the extent that such
Indemnified Liabilities arise from the gross negligence, illegal acts, fraud or
willful misconduct of Lender.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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