                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                    ________

1.  Organization and Basis of Presentation:

    Organization

    Beacon Properties, L.P. (the "Operating Partnership") was organized as a
    Delaware limited partnership in April 1994 and commenced operations
    effective on May 26, 1994. Simultaneously with the closing of the Initial
    Public Offering (the "IPO") of Beacon Properties Corporation  (the 
    "Company"), which is the sole general partner and a limited partner of the
    Operating Partnership, contributed its interest in two properties and
    approximately $173.4 million, the net proceeds of the IPO, to the Operating
    Partnership in exchange for partnership interests ("Units"). The Operating
    Partnership was formed to continue and expand the commercial real estate
    business of The Beacon Group (the "Predecessor").

    The Operating Partnership specializes in property ownership, management,
    leasing, design and development and currently owns or has an interest in
    123 properties totaling approximately 20.7 million square feet (the
    "Properties").

    Basis of Presentation

    The financial statements of the Operating Partnership are consolidated and
    include all the accounts of the Operating Partnership and its subsidiaries.
    All significant intercompany balances and transactions have been
    eliminated.

    The accompanying financial statements are unaudited; however, they have
    been prepared in accordance with generally accepted accounting principles
    for interim financial information and in conjunction with the rules and
    regulations of the Securities and Exchange Commission.  Accordingly, they
    do not include all of the disclosures required by generally accepted
    accounting principles for complete financial statements.  In the opinion of

3.  Mortgage Notes Payable:
    On April 30, 1997, in connection with the acquisition of Centerpointe I and
    II located in Fairfax County, Virginia, the Operating Partnership assumed
    $30 million of mortgage debt secured by the properties. The mortgage has a
    remaining term of 3.9 years, bears interest at 7.32% and requires monthly
    installments of interest only until December 1, 1999, and principal and
    interest during the remaining term based on a 25-year amortization
    schedule.

    On May 23, 1997, in connection with the acquisition of Westbrook Corporate
    Center located in suburban Chicago, the Operating Partnership assumed
    approximately $82 million of million of mortgage debt and borrowed $24
    million of additional mortgage debt secured by the properties. The mortgage
    has a term of ten years, bears interest at 8.00% and requires monthly 
    installments of principal and interest based on a 26-year amortization 
    schedule.

4.  Note Payable, Credit Facility:
    On April 8, 1997, the Operating Partnership replaced its $300 million
    secured floating-rate credit facility (the "Credit Facility") with an
    unsecured facility and decreased the interest rate on the Credit Facility
    from the Eurodollar rate plus 175 basis points (1.75%) to the Eurodollar
    rate plus 120 basis points (1.20%). Additionally, on April 30, 1997, the
    maximum loan amount available under the Credit Facility was increased to
    $350 million.

    On August 8, 1997, the Operating Partnership amended the Credit Facility to
    provide for a competitive bid option and a decrease in the interest rate on
    the Credit Facility from the Eurodollar rate plus 120 basis points (1.20%)
    to the Eurodollar rate plus 90 basis points (.90%).

    As a result of the new unsecured Credit Facility, the Operating Partnership
    recorded an extraordinary item of $2.6 million in connection with the
    write-off of fees and costs to acquire the prior secured Credit Facility.

5.  Commitments and Contingencies:
    In connection with the acquisition of the Westbrook Corporate Center, the
    Operating Partnership has agreed to maintain non-recourse financing assumed
    from the sellers for a 10 year period and not to sell or otherwise transfer
    any portion of the property prior to the tenth anniversary of the closing
    date. If the Operating Partnership should choose not to maintain the
    non-recourse provisions of the existing or new debt, or should choose to
    sell the property, within the 10 year period it shall be required to make
    payments to the sellers.

6.  Environmental issue:
    Site assessments at 175 Wyman Street have identified the presence of
    trichloroethylene and tetrachloroethylene in the groundwater (the "Existing
    Groundwater Condition").  The chemicals in the groundwater are believed to
    be associated with former manufacturing use of the Property.  Prior to the
    acquisition of the Property by the Operating Partnership, the former owner
    of the Property, Hewlett-Packard Company, reported the Existing Groundwater
    Condition to the Massachusetts Department of Environmental Protection (the
    "DEP").  Hewlett-Packard Company sought and obtained approval from DEP of
    an Immediate Response Action which involves installation of a system to
    extract and treat contaminated groundwater (the "System").  According to
    its submissions to DEP, Hewlett-Packard Company is in the process of
    installing the System.  In its purchase and sale agreement with the
    Operating Partnership, Hewlett-Packard Company agreed to indemnify the
    Operating Partnership against costs of remediating the Existing Groundwater
    Condition and claims by off-site parties for property damage, personal
    injury, and natural resource damages related to the Existing Groundwater
    Condition (the "Indemnity").  Any claim under the Indemnity is subject to
    the risk that the indemnifying party will lack sufficient assets to satisfy
    the claim.  Moreover, any claim under the Indemnity may be subject to
    substantial defenses, including but not limited to the defense that the
    claim was exacerbated by the Operating Partnership's development or
    redevelopment of the Property, as to which matters the Operating Partnership
    has indemnified Hewlett-Packard Company. However, the Operating Partnership
    does not believe that any such liability would have a material adverse
    effect on its financial condition, results of operations and liquidity.

7.  Pro Forma Results (unaudited):

    The following unaudited pro forma operating results for the Operating
    Partnership have been prepared as if the 1996 and 1997 stock offerings and
    the 1996 and 1997 property acquisitions and dispositions had occurred on
    January 1, 1996. Unaudited pro forma financial information is presented for
    informational purposes only and may not be indicative of what the actual
    results of operations of the Operating Partnership would have been had the
    events occurred as of January 1, 1996, nor does it purport to represent the
    results of operations for future periods.

8.  Agreement and Plan of Merger: 

    On September 15, 1997, Equity Office Properties Trust ("EOP"), EOP
    Operating Limited Partnership, a Delaware limited partnership of which EOP
    is the managing general partner ("EOP Partnership") and the Company and
    the Operating Partnership entered into an Agreement and Plan of Merger (the 
    "Merger Agreement"). The Merger Agreement provides for a merger of the
    Company with and into EOP (the "Merger") and a merger of the Operating
    Partnership with and into EOP Partnership or a limited liability EOP or
    limited partnership wholly owned directly or indirectly by EOP Partnership
    (the "Partnership Merger" and, together with the Merger, the "Mergers").

    At the effective time of the Mergers, (1) each outstanding share of common
    stock, $0.01 par value per share, of the Company ("Company Common Shares")
    will be converted into 1.4063 common shares of beneficial interest, $0.01
    par value per share, of EOP ("EOP Common Shares"), with cash in lieu of
    the issuance of any fractional interests, (ii) each share of 8.98% Series A
    Cumulative Redeemable Preferred Stock, liquidation preference $25.00 per
    share, of the Company ("Company Preferred Shares") will be converted into
    a 8.98% Series A Cumulative Redeemable Preferred Share, liquidation
    preference $25.00 per share, of EOP ("EOP Preferred Shares"), and (iii)
    each common partnership unit of the Operating Partnership (a "Operating
    Partnership Unit") will be converted into 1.4063 Class A Units of EOP
    Partnership ("EOP OP Units").

    The Mergers are subject to customary closing conditions, including the
    approval of the Merger by the shareholders of EOP and the Company and the
    approval of the Partnership Merger, to the extent necessary, by the
    partners of EOP Partnership and the Operating Partnership. The Company may
    terminate the Merger Agreement if the average of the closing prices of EOP
    Common Shares on the New York Stock Exchange for all trading days during
    the period of twenty (20) consecutive trading days ending on the seventh
    (7th) trading day prior to the date of the special meeting of the
    shareholders of the Company called to vote upon the Merger is less than
    $27.39. Subject to certain conditions and limitations, either party may
    terminate the Merger Agreement if the Merger has not occurred by April 15,
    1998.

9.  Subsequent Events:

    On October 1, 1997, the Operating Partnership signed an additional $200
    million term loan agreement with BankBoston which matures in April 1998.

    On October 1, 1997, the Operating Partnership acquired the Civic Opera
    Building located in Chicago, Illinois for aggregate consideration of
    approximately $59.6 million, consisting of assumption of $31.8 million of
    mortgage debt, approximately $21.1 million in cash and the issuance of $6.7
    million of units of limited partnership interest in the Operating
    Partnership ("Units").

    On October 8, 1997, the Operating Partnership acquired 200 West Adams
    located in Chicago, Illinois for aggregate consideration of approximately
    $72.2 million.

    On October 20, 1997, the Operating Partnership acquired Lakeside located in
    Atlanta, Georgia for aggregate consideration of approximately $38.0
    million.

    On October 30, 1997, the Operating Partnership declared a quarterly
    distribution of $31.5 million payable on November 21, 1997 to partners of
    record on November 7, 1997.

                      REPORT OF INDEPENDENT ACCOUNTANTS


To the Partners of
Beacon Properties, L.P.:



We have audited the consolidated balance sheets of Beacon Properties, L.P. as
of December 31, 1996 and 1995, and the related consolidated statements of
operations, partners' capital and cash flows for the years ended December 31,
1996 and 1995 and the period May 26, 1994 to December 31, 1994. We have also
audited the combined statement of operations, owners' equity and cash flows of
the Predecessor, more fully described in Note 1, for the period January 1, 1994
to May 25, 1994. These consolidated financial statements are the responsibility
of the Operating Partnership's management. Our responsibility is to express an
opinion on these consolidated financial statements 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 financial statements referred to above present
fairly, in all material respects, the consolidated financial position of Beacon
Properties, L.P. as of December 31, 1996 and 1995 and the consolidated results
of its operations and its cash flows for the years ended December 31, 1996 and
1995 and the period May 26, 1994 to December 31, 1994, and the combined results
of operations and cash flows of the Predecessor for the period January 1, 1994
to May 25, 1994 in conformity with generally accepted accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                            (dollars in thousands)


1.   Organization, Offerings and Acquisitions:

     Beacon Properties, L.P. (the "Operating Partnership") was organized as a
     Delaware limited partnership in April 1994 and commenced operations
     effective on May 26, 1994. The Operating Partnership was formed to continue
     and expand the commercial real estate development, construction,
     acquisition, leasing, design and management business of The Beacon Group
     (the "Predecessor").

     Simultaneously with the closing of the initial public offering (the "IPO")
     of Beacon Properties Corporation (the "Company"), which is the sole general
     partner and a limited partner of the Operating Partnership, the Company
     contributed its interests in two properties and approximately $173.4
     million, the net proceeds of the IPO, to the Operating Partnership in
     exchange for partnership interests ("Units").

     The following schedule summarizes the Operating Partnership's interest in
     the properties as a result of the initial and subsequent capital
     contributions of the Company, and the related acquisition of properties
     and partnership interests. All properties have been consolidated unless
     otherwise indicated in the notes:

2.   Summary of Significant Accounting Policies:

     Business

     The Operating Partnership currently has interests in a portfolio of 104
     Class A office properties and other commercial properties containing
     approximately 15.8 million rentable square feet located in Boston, Atlanta,
     Chicago, Los Angeles, San Francisco and Washington, D.C.

     The Operating Partnership also owns and operates commercial real estate
     development, acquisition, leasing, design and management businesses. The
     Operating Partnership currently manages approximately 2.9 million square
     feet of commercial and office space owned by third parties in various
     locations, including Boston, Waltham, and Springfield, Massachusetts and
     Chicago, Illinois.

     Principles of Consolidation

     The accompanying financial statements of the Operating Partnership have
     been prepared on a consolidated basis which include all the accounts of the
     Operating Partnership and its subsidiaries. All significant intercompany
     balances and transactions have been eliminated. The Operating Partnership's
     consolidated financial statements reflect the properties acquired at their
     historical basis of accounting to the extent of the acquisition of
     interests from the Predecessors' owners who continued on as investors. The
     remaining interests acquired from the Predecessors' owners have been
     accounted for as a purchase and the excess of the purchase price over the
     related historical cost basis was allocated to real estate.

     The accompanying financial statements of the Predecessor have been
     presented on a combined basis which include all the contributed properties
     and the management, leasing and design entities.

     Real Estate


     Buildings and improvements are recorded at cost and are depreciated on the
     straight-line and declining balance methods over their estimated useful
     lives of nineteen to forty years and fifteen to twenty years, respectively.
     The cost of buildings and improvements includes the purchase price of the
     property or interests in property, legal fees, acquisition costs and
     interest, property taxes, capitalized interest, and other costs incurred
     during the period of construction. The Operating Partnership capitalized
     interest costs of $1.0 million in 1996, $0.1 million in 1995, and $0 in
     1994. 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 periodically reviews
     its properties to determine if its carrying costs will be recovered from
     future operating cash flows. In cases where the Operating Partnership does
     not expect to recover its carrying costs, the Operating Partnership
     recognizes an impairment loss. No such losses have been recognized to date.

                                      23


<PAGE>   24

     Tenant improvements are depreciated over the terms of the related leases.
     Furniture, fixtures and equipment are depreciated using the straight-line
     and declining balance methods over their expected useful lives of five to
     seven years.

     Expenditures for maintenance and repairs are charged to operations as
     incurred. Significant renovations or betterments which extend the economic
     useful life of the assets are capitalized.

     Deferred Financing and Leasing Costs

     Deferred financing costs include fees and costs incurred to obtain
     long-term financings, and are amortized over the terms of the respective
     loans on a basis which approximates the interest method. Deferred leasing
     costs incurred in the successful negotiation of leases, including
     brokerage, legal and other costs, have been deferred and are being
     amortized on a straight-line basis over the terms of the respective leases.

     Cash and Cash Equivalents

     Cash and cash equivalents consist of highly liquid assets with original
     maturities of three months or less from the date of purchase. The majority
     of the Operating Partnership's cash and cash equivalents are held at major
     commercial banks. The Operating Partnership has not experienced any losses
     to date on its invested cash. The carrying value of the cash and cash
     equivalents approximates market.


     Restricted Cash

     Restricted cash consists of cash held in escrow as required by lenders to
     satisfy real estate taxes and tenant improvement costs.


     Investments in and Advance to Joint Ventures and Corporations

     The Operating Partnership uses the equity method of accounting for its
     earnings in property joint ventures and corporations which it does not
     control. Losses in excess of investments are not recorded where the
     Operating Partnership is a limited partner and has not guaranteed nor
     intends to provide any future financial support to the respective
     properties.

     Mortgage Notes Receivable

     Discounts from the principal balance on mortgage loans receivable, net of
     acquisition costs, are amortized as interest income over the due date of
     the related loans using the effective yield method, based on management's
     evaluation of the current facts and circumstances and the ultimate ability
     to collect the principal balances of such loans.

                                      24

<PAGE>   25

     Revenue Recognition

     Base rental income is reported on a straight-line basis over the terms of
     the respective leases. The impact of the straight-line rent adjustment
     increased revenues for the Operating Partnership by $6.6 million, $3.7
     million and $1.9 million and increased its proportionate share of equity in
     net income of property joint ventures and corporations by $0.1 million,
     $0.2 million and $0.3 million for the years ended December 31, 1996 and
     1995 and the period May 26, 1994 to December 31, 1994, respectively.
     Management fees are recognized as revenue as they are earned.

     Income Taxes

     Income taxes are not considered in the accompanying financial statements
     since such taxes, if any, are the responsibility of the partners.

     Interest Rate Protection Agreements

     The Operating Partnership has entered into interest rate protection
     agreements to reduce the impact of certain changes in interest rates. These
     agreements are held for purposes other than trading. Amounts paid for the
     agreements are amortized over the lives of the agreements on a basis which
     approximates the interest method. Payments under interest rate swap
     agreements are recognized as adjustments to interest expense when incurred.
     The Operating Partnership's policy is to write off unamortized amounts paid
     under interest rate protection agreements, when the related debt is paid
     off or there is a termination prior to the maturity of the agreements. The
     Operating Partnership is exposed to credit loss in the event of
     nonperformance by the other parties to the interest rate protection
     agreements. However, the Operating Partnership does not anticipate
     nonperformance by the counterparties.

     Risks and Uncertainties

     The preparation of financial statements in conformity with generally
     accepted accounting principles requires management to make estimates and
     assumptions that affect the reported amount of assets and liabilities and
     disclosure of contingent assets and liabilities. Actual results could
     differ from those estimates.

     Reclassifications

     Certain prior year balances have been reclassed to conform with current
     year presentation.

     Operating Partnership has an indirect interest. The terms of the notes
     require interest-only payments at 8.71% quarterly on a principal balance of
     approximately $63.0 million and are due on April 1, 1999. The term may be
     extended for up to three years under certain conditions. The Operating
     Partnership also has an option to purchase from an affiliate other mortgage

     extraordinary item of $2.2 million in connection with the write-off of fees

     condition to transfer the assets to the Operating Partnership, these items
     were recorded by the Predecessor entity.

7.   Note Payable -- Credit Facility:

     The Operating Partnership presently has a three-year, $300 million
     revolving credit facility (the "Credit Facility"). The Credit Facility
     matures in June 1999 and is collateralized by cross-collateralized
     mortgages and assignment of rents on certain properties.


     Outstanding balances under the Credit Facility bear interest, at the
     Company's option, at either (i) the higher of (x) Bank of Boston's base
     interest rate and (y) one-half of one percent (1/2%) above the overnight
     federal funds effective rate or (ii) the Eurodollar rate plus 175 basis
     points (1.75%). The Company has an interest rate protection agreement
     through May 1997 with respect to $135 million of the Credit Facility,
     which provides for offsetting payments to the Company in the event that
     90-day LIBOR exceeds 9.47% per annum. Effective May 1997 through May 1999,
     the Company has an interest rate protection agreement with respect to
     $137.5 million of the Credit Facility, which provides for offsetting
     payments to the Company in the event that 90-day LIBOR exceeds 8.75% per
     annum. This interest rate protection arrangement may be applied during
     four quarters of the period May 1997 to May 1999.


     The outstanding balance of the Credit Facility at December 31, 1996 was
     $153.0 million. The weighted average amount outstanding during the years
     ended December 31, 1996 and 1995 and the period May 26, 1994 to December
     31, 1994 was $42.3 million, $99.7 million and $50.4 million, respectively.
     The weighted average interest rate on amounts outstanding during the years
     ended December 31, 1996 and 1995 and the period May 26, 1994 to December
     31, 1994 was approximately 7.78%, 8.25% and 7.57%, respectively. The
     applicable interest rate under the Credit Facility at December 31, 1996 was
     8.25%.


     Based upon the Credit Facility's variable interest rate, the Operating
     Partnership has determined that the fair value of the Credit Facility
     approximates its carrying value. The Operating Partnership determines the
     fair value of its interest rate agreement based upon the quoted market
     prices of similar instruments. Based on this analysis, the Operating
     Partnership has determined that the fair value of this instrument
     approximates its carrying value.

     As a result of the substantial modification of the terms of the Credit
     Facility, the Company recorded an extraordinary item of $1.7 million in
     connection with the write-off of fees and costs relating to the prior
     Credit Facility.

     In 1995, the Operating Partnership entered into an agreement to lease its
     home office from a joint venture in which the Operating Partnership has an
     indirect interest. It previously subleased home office space from another
     affiliate. Rental expense related to these arrangements was $1.3 million,
     $0.3 million and $0.1 million for the years ended December 31, 1996 and
     1995 and the period May 26, 1994 to December 31, 1994, respectively.

     Future minimum rental payments at December 31, 1996 for the Operating
     Partnership's home office are $1.3 million for 1997, $1.4 million for 1998
     through 2001, and $1.0 million for 2002.


10.  Limited Partners' Capital Interest

     Pursuant to the Operating Partnership Agreement, certain limited partners
     in the Operating Partnership have the right to redeem all or any portion
     of their Units for cash from the Operating Partnership or, at the election
     of the Company, for shares of common stock or cash as selected by the
     Company. The amount of cash to be paid to the limited partner if the
     redemption right is exercised and the cash option is selected will be



                                      31

<PAGE>   32

     based on the trading price of the Company's common stock at that time.

     Such limited partners' redemption rights are not included in partners'
     capital. Accordingly, the accompanying consolidated balance sheets have
     been retroactively reclassified to reflect the limited partners' capital
     interest in the Operating Partnership, measured at redemption value. This
     reclassification results in a reduction of partners' equity of $69.7
     million and $15.0 million as of December 31, 1996 and 1995, respectively
     as a result of the increase in the redemption value.


11.  Commitments and Contingencies:

     Pension Plan

     The Operating Partnership participates in a multiemployer defined-benefit
     pension plan with some of its affiliates. This plan covered substantially
     all full-time nonunion employees. The Operating Partnership's portion of
     pension expense for the years ended December 31, 1996 and 1995 and the
     period May 26, 1994 to December 31, 1994, was $0.2 million, $0.1 million,
     and $0.1 million, respectively. The Predecessor's comparable allocated
     portion of pension expense amounted to $0.1 million for the period
     January 1, 1994 to May 25, 1994.

     401(k) Plan

     The eligible employees of the Operating Partnership participate in a
     contributory savings plan with some of its affiliates. Under the plan, the
     Operating Partnership may match contributions made by eligible employees
     based on a percentage of the employee's salary. Currently, the Operating
     Partnership matches 25% of contributions up to 3% of such employee's salary
     (up to $30). The matching amount may be changed from time to time by the
     Board of Directors of the Company. Expenses under this plan for 1996, 1995
     and 1994 were not material.

     Contingencies

     The Operating Partnership 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 Operating Partnership.

     Lease

     The South Station property is subject to a ground lease expiring in 2024.
     The lease provides two 15-year extension options. Under certain conditions,
     the lessor reserves the right to terminate the lease at the end of the
     initial term or at the end of the first extension period and pay the lessee
     an amount based on a formula payment of fair value. The minimum rents in
     connection with the lease are substantially based on percentage rent until
     1997. The Operating Partnership is obligated to provide loans to the lessor
     under certain conditions subject to a maximum of $0.9 million.  As of

                                      32


<PAGE>   33

     December 31, 1996, no loans were outstanding.

     Environmental

     A former tenant of Crosby Corporate Center has agreed to perform the
     necessary investigation and cleanup actions regarding remediation of
     possible contamination, bear all costs associated with such cleanup
     activities and indemnify the Operating Partnership for any costs or damages
     it incurs in connection with such contamination. As the owner of the
     property, however, the Operating Partnership could be held liable for the
     costs of such activities if the former tenant fails to undertake such
     actions.

     As a lessee of certain property, the Operating Partnership has received an
     indemnity from the owner to the extent the Operating Partnership is
     assessed costs relating to environmental cleanup.

     Site assessments at the New England Executive Park have identified
     contamination in the groundwater at a monitoring well which flows into an
     aquifer, which supplies drinking water to the Town of Burlington. The Town
     of Burlington has allocated funds for, and is in the process of
     constructing, a groundwater treatment facility at its drinking water supply
     that draws from the subject aquifer. The Operating Partnership has been
     advised that such treatment facility has the capacity to treat any
     contaminants which may be derived from the groundwater passing
     beneath the New England Executive Park. Although the Town's water treatment
     facility does not relieve the Operating Partnership of potential liability
     for the presence of the contaminants, the Operating Partnership does not
     believe that any such liability would have a material adverse effect on the
     Operating Partnership.

     Based on site assessments performed at 245 First Street which have
     identified the presence of oil that slightly exceeds the concentration that
     requires reporting to the Massachusetts Department of Environmental
     Protection, an environmental consultant has advised the Operating
     Partnership that applicable regulatory requirements can be satisfied
     without the need to perform any remediation at the property. The Operating
     Partnership could be held liable for costs associated with the
     contamination that has been identified, although the Operating Partnership
     does not believe that such costs would have a material adverse effect on
     the Operating Partnership.

     In connection with the acquisition of the John Marshall land, the sellers
     have reported the findings of contamination to the Virginia Department of
     Environmental Quality and have retained an environmental consultant to
     prepare a remediation plan. Units valued at approximately $1.0 million were
     escrowed from the purchase price to be released to the seller upon
     performance of remediation pursuant to a remediation plan approved by the
     Operating Partnership. The escrow further provides that the Operating
     Partnership may receive some or all of the remaining escrowed Units upon
     certain conditions.

     Management does not believe that any costs, if incurred, would have a
     material adverse effect on the financial condition, annual results of

                                      33

     operations, or liquidity of the Operating Partnership.



     Other

     The Operating Partnership has an obligation to pay $17.0 million in
     connection with the acquisition of real estate upon the achievement of
     conditions regarding occupancy or rental income levels.


     In connection with the acquisition of the John Marshall I, E.J. Randolph
     and Northridge I properties, the Operating Partnership has agreed to
     maintain the non-recourse financing assumed from the sellers for a five
     year period and not to dispose of the property for a seven year period. If
     the Operating Partnership should choose not to maintain the non-recourse
     provisions of the existing or new debt, or sell the properties, within
     these respective time periods it shall be required to make payments to the
     sellers of approximately $6.0 million in 1997, reducing ratably to zero
     through 2003.



12.  Future Minimum Rents:

     Future minimum rentals to be received under noncancelable tenant leases for
     all fully consolidated properties at December 31, 1996 are due for years
