                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)

     DEFINITION OF TERMS.  Capitalized terms used but not defined herein are as
defined in the Company's Annual Report on Form 10-K for the year ended December
31, 1999 (the "Form 10-K").

     The consolidated financial statements of the Company have been prepared
pursuant to the Securities and Exchange Commission ("SEC") rules and
regulations. The following notes highlight significant changes to the notes to
the December 31, 1999 audited consolidated and combined financial statements of
Equity Office Properties Trust and should be read in conjunction with the
financial statements and notes thereto included in the Form 10-K and present
interim disclosures as required by the SEC.

NOTE 1 -- BUSINESS AND FORMATION OF THE COMPANY

     As used herein, "Company" means Equity Office Properties Trust, a Maryland
real estate investment trust, together with its subsidiaries, including the
Operating Partnership. The Company was formed on October 9, 1996 to continue and
expand the national office property business organized by Mr. Samuel Zell,
Chairman of the Board of Trustees of the Company, and to complete the
Consolidation. The Company completed its IPO on July 11, 1997. The Company is a
fully integrated, self -- administered and self-managed real estate company
engaged in acquiring, owning, managing, leasing and renovating office properties
and parking facilities. The Company elected to be taxed as a REIT for federal
income tax purposes and generally will not be subject to federal income tax if
it distributes 100% of its taxable income and complies with a number of
organizational and operational requirements. As of June 30, 2000, the Company
owned or had an interest in 381 office properties (the "Office Properties")
containing approximately 97.3 million rentable square feet of office space and
owned nine stand-alone parking facilities (the "Parking Facilities" and,
together with the Office Properties, the "Properties") containing approximately
14,244 parking spaces. The weighted average occupancy of the Office Properties
at June 30, 2000 was approximately 94.1%. The Office Properties are located in
104 submarkets in 38 markets in 24 states and the District of Columbia. The
Office Properties, by rentable square feet, are located approximately 50% in
CBDs and 50% in suburban markets.

NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  Basis of Presentation

     The Company's assets, which include investments in joint ventures, are
primarily owned by, and its operations are substantially conducted through, the
Operating Partnership. The Company is the general partner of the Operating
Partnership. Due to the Company's ability as general partner to control the
Operating Partnership and various other property-holding entities and other
subsidiaries, each such entity has been consolidated with the Company for
financial reporting purposes.

     The Cornerstone Merger (as defined in Note 3) was accounted for using the
purchase method in accordance with Accounting Principles Board Opinion No. 16.
The fair value of the consideration given by the Company in the Cornerstone
Merger was used as the valuation basis for the merger. The assets acquired and
the liabilities assumed of Cornerstone were recorded at their relative fair
values as of June 19, 2000 (the "Cornerstone Closing Date"). The results of
operations of the Cornerstone properties for the period from the Cornerstone
Closing Date through June 30, 2000 are included in the Company's consolidated
statements of operations.

  Use of Estimates

     The preparation of the consolidated financial statements of the Company in
conformity with accounting principles generally accepted in the United States
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 periods. Actual results could differ
from those estimates.

  Unaudited Interim Statements

     The consolidated financial statements of the Company as of and for the
three and six months ended June 30, 2000 and 1999 and related footnote
disclosures are unaudited. In the opinion of management, such financial
statements reflect all adjustments necessary for a fair presentation of the
results of the interim periods. All such adjustments are of a normal, recurring
nature.

  Reclassifications

     Certain reclassifications have been made to the previously reported 1999
statements in order to provide comparability with the 2000 statements reported
herein. These reclassifications have not changed the 1999 results or
shareholders' equity.

NOTE 3 -- CORNERSTONE MERGER

     On June 19, 2000, the Company, the Operating Partnership, Cornerstone
Properties Inc. ("Cornerstone") and Cornerstone Properties Limited Partnership
("Cornerstone Partnership") consummated the merger of Cornerstone with and into
the Company and Cornerstone Partnership with and into the Operating Partnership
(the "Cornerstone Merger") at a cost of approximately $4.5 billion. The purchase
price consisted of:

          (i) the Company's issuance of approximately 51.3 million Common Shares
     valued at $24.68 per share and the issuance of stock options for a total of
     approximately $1,271.3 million;

          (ii) the Operating Partnership's issuance of approximately 12.4
     million Units to third parties valued at $24.68 per Unit for a total of
     approximately $306.0 million;

          (iii) the cash redemption of approximately 58.6 million Cornerstone
     common shares valued at $18.00 per share for a total of approximately
     $1,053.9 million;

          (iv) the cash redemption of approximately 3.0 million Cornerstone
     preferred shares valued at $18.00 per share for a total of approximately
     $57.6 million, plus accrued but unpaid dividends;

          (v) the assumption of approximately $1,304.9 million of secured debt
     and $415.5 million of unsecured debt;

          (vi) the payment of merger costs of approximately $72.1 million; and

          (vii) the assumption of net liabilities of approximately $9.6 million.

     The cash portion of the Cornerstone Merger of approximately $1.2 billion
was partially funded from the $1.0 Billion Credit Facility and a new revolving
credit facility. Concurrently with the Cornerstone Merger, the Company borrowed
$1.0 billion from the $1.0 Billion Credit Facility and amended the facility into
a term loan (the "Term Loan"). The Term Loan bears interest at LIBOR plus 80
basis points and matures on May 29, 2001. If the Company obtains net proceeds
from the disposition of a Property, (excluding proceeds from a tax-deferred
property disposition), the issuance of unsecured notes or the issuance of Common
Shares/Units, the net proceeds must be used to repay any amounts outstanding
under the Term Loan up to the then current unpaid balance of the Term Loan.

     The remaining cash consideration in the Cornerstone Merger was funded from
a new $1.0 billion revolving credit facility obtained at the time of the merger
(the "Line of Credit"). The Line of Credit bears interest at LIBOR plus 60 basis
points and matures on June 19, 2003. There is also a facility fee of $2.0
million per annum on the Line of Credit payable quarterly. In addition, the
Company assumed interest rate protection agreements in the notional amount of
$250 million effectively converting a portion of the Line

of Credit to a fixed-blended interest rate of 4.6%. The interest rate protection
agreements terminate in December 2000 and January 2001.

     As a result of the Cornerstone Merger, the Company acquired an interest in
82 Office Properties containing approximately 18.9 million square feet of office
space. In addition, in connection with the merger, the Board of Trustees of the
Company was increased from 11 to 14 members. The new members are William Wilson
III, formerly chairman of the board of Cornerstone, John S. Moody, formerly
president and chief executive officer of Cornerstone, and Jan H.W.R. van der
Vlist, director of real estate for Stichting Pensioenfonds voor de Gezondheid,
Gaestelijke en Meatschappelljke Belangen.

NOTE 4 -- ACQUISITIONS

     On April 10, 2000, the Company acquired the remaining 30% interest in
Metropoint II for approximately $8.3 million in cash. Metropoint II was a
development project which was completed in May 1999. The Office Property
consists of approximately 150,181 square feet and is located in Denver,
Colorado.

     On June 30, 2000, the Company acquired the remaining 20% interest in Sunset
North Corporate Campus from Wright Runstad Associates Limited Partnership
("WRALP"), an affiliate of the Company, for approximately $14.9 million in cash.
Upon acquisition of the property, the Company assumed and immediately repaid a
$65.7 million mortgage note secured by the property. Sunset North Corporate
Campus was a development project which was completed in December 1999. The
project consists of three Office Properties containing approximately 460,629
square feet and is located in Bellevue, Washington.

     Prior to the acquisition of the remaining interests in Metropoint II and
Sunset North Corporate Campus, the Company accounted for its interest in these
properties under the equity method of accounting and classified its net equity
investment as investment in unconsolidated joint ventures on the consolidated
balance sheet and its interest in the net income from investment in
unconsolidated joint ventures was reflected in the consolidated statements of
operations. Upon the acquisition of the remaining interest in the Properties,
the Company consolidated the financial condition and results of operations of
Metropoint II and Sunset North Corporate Campus.

     On May 23, 2000, the Company acquired a vacant parcel of land located in
Fairfax, Virginia, for approximately $8.1 million in cash from an unaffiliated
party.

NOTE 5 -- DISPOSITIONS

     On May 17, 2000, the Company disposed of 11 parking facilities containing
6,992 parking spaces for approximately $180 million in cash to an unaffiliated
party. The parking facilities disposed of were 1111 Sansom St., 15th and Sansom
St., 1602-34 Chancellor, 1616 Sansom St., Boston Harbor, Capitol Commons, Forbes
and Allies, Juniper/Locust, Milwaukee Center, and Riverfront/Stanwix. The sale
resulted in a gain of approximately $23.9 million.

     On June 2, 2000, the Company entered into a joint venture agreement with an
unaffiliated party and sold a 49.9% interest in Bank of America Tower for
approximately $209.6 million resulting in a gain on sale of approximately $13.1
million. The property consists of approximately 1,537,932 square feet and is
located in Seattle, Washington. Prior to the sale, the Company consolidated the
financial condition and results of operations of the property. Upon the sale,
the Company retained a 50.1% equity interest in the property and shares equally
in the control of operations and major decisions of the property. Therefore, the
Company accounts for its interest under the equity method of accounting and
classifies its net equity investment of approximately $106.0 million as
investment in unconsolidated joint ventures on the consolidated balance sheet
and its interest in the net income is reflected in the consolidated statement of
operations as income from investment in unconsolidated joint ventures. At close,
the joint venture obtained a $195 million mortgage secured by the property. The
note bears interest at LIBOR plus 1.15% and matures on December 14, 2004. As
                                       10

a condition of the mortgage, the joint venture purchased a 7.85% LIBOR based
interest rate cap, thereby capping the effective interest rate on the mortgage
at 9.0% for three years.

     On June 30, 2000, the Company disposed of Park Plaza, which was acquired in
connection with the Cornerstone Merger, to an unaffiliated party for

property.

NOTE 14 -- COMMITMENTS AND CONTINGENCIES

  Concentration of Credit Risk

     The Company maintains its cash and cash equivalents at financial
institutions. The combined account balances at each institution typically exceed
FDIC insurance coverage and, as a result, there is a concentration

                                       17
<PAGE>   18
                         EQUITY OFFICE PROPERTIES TRUST

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

of credit risk related to amounts on deposit in excess of FDIC insurance
coverage. Management of the Company believes that the risk is not significant.

  Environmental

     The Company, as an owner of real estate, is subject to various
environmental laws of federal and local governments. Compliance by the Company
with existing laws has not had a material adverse effect on the Company's
financial condition and results of operations, and management does not believe
it will have such an impact in the future. However, the Company cannot predict
the impact of new or changed laws or regulations on its current Properties or on
properties that it may acquire in the future.

  Litigation

     The Company has become a party to various legal actions resulting from the
operational activities transferred to the Operating Partnership in connection
with the Consolidation and the Cornerstone Merger. These actions are incidental
to the transferred business and management does not believe that these actions
will have a material adverse effect on the Company.

     Neither the Company nor any of the Properties is presently subject to any
material litigation nor, to the Company's knowledge, is any litigation
threatened against the Company or any of the Properties, other than actions
which the Company does not believe to be material, or routine actions for
negligence and other claims and administrative proceedings arising in the
ordinary course of business, some of which are expected to be covered by
liability insurance and all of which collectively are not expected to have a
material adverse effect on the liquidity, business, results of operations or
financial condition of the Company.

  Commitments

     In July 1998, the Company entered into an agreement to purchase the World
Trade Center project in Seattle, Washington. The property consists of
approximately 186,787 square feet of office space and is 100% preleased to a
single tenant. The Company expects to acquire the property in late August 2000
for approximately $39.0 million. This transaction is contingent upon certain
terms and conditions as set forth in the purchase agreement. There can be no
assurance that this transaction will be consummated as described above.

     In accordance with the agreement governing the Company's investment in
WRALP, the Company agreed to make available to WRALP up to $20.0 million in
additional financing or credit support for future development. As of June 30,
2000, no amounts have been funded pursuant to this agreement. However, the
Company has guaranteed WRALP's line of credit, which has an outstanding balance
of approximately $12.9 million as of June 30, 2000.

     The Company and Wilson/Equity Office, LLC, entered into an agreement to
purchase a 12.9 acre vacant land parcel in San Raphael, California for
approximately $30.3 million from an unaffiliated party. The Company's interest
in this joint venture is 60%. The Company also has an interest in Wilson/Equity
Office, LLC which was formed in June 2000 and operated under an interim
operating agreement. This agreement was subsequently finalized on August 1,
2000. The transaction is contingent upon certain terms and conditions as set
forth in the purchase agreement. There can be no assurance that this transaction
will be consummated as described above.

  Contingencies

     On August 13, 2000 (or August 13, 2001 at the option of the WR Holders),
the WR Holders can require the Company to purchase all or a portion of the
remaining 1,717,844 Common Shares issued to them at a price equal to $31.50 per
Common Share. Prior to such date, if the WR Holders sell all or a portion of
their Common Shares to a third party for a price less than $29.10625, then the
Company is obligated to pay to the WR Holders for each Common Share sold at such
lower price an amount equal to the difference between
                                       18
<PAGE>   19
                         EQUITY OFFICE PROPERTIES TRUST

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

$29.10625 and such lower price, not to exceed $3.00 per Common Share. Any
amounts paid by the Company as a result of such sales will be recorded as a
reduction in shareholders' equity. For put options exercised on August 13, 2000,
any amounts paid up to $29.10625 per Common Share would be reflected as a
reduction in shareholders' equity and the portion of any amounts paid in excess
of $29.10625 per Common Share (not to exceed $2.39375 per Common Share up to an
aggregate of approximately $4.1 million) will be reflected as a preferred
distribution. The $4.1 million portion of the total potential payment is being
amortized by the Company on a straight-line basis over the period between August
13, 1999 and August 13, 2000. The Company will not incur any loss on this
transaction if the put option is not exercised.

     In connection with the acquisition of Worldwide Plaza on October 1, 1998,
the Company issued a transferable put option on the 6,861,166 Units which is
exercisable only on the third anniversary of closing with an estimated fair
value of approximately $27.4 million. This option entitles its holder to
additional Common Shares, the number of which shall be determined using a
formula based on the extent, if any, that the Common Shares are then trading at
less than $29.05 per share.

NOTE 15 -- SUBSEQUENT EVENTS

     1. In July, 2000, the Board of Trustees of the Company declared a third
quarter distribution on the Series B Preferred Shares of $0.65625 per share. The
distribution will be paid on August 15, 2000 to holders of record as of August
1, 2000.

     2. On July 11, 2000, the Company acquired Two Lafayette Center, a 130,704
square foot office building in Washington, D.C., for approximately $29.0 million
in cash from an unaffiliated party.

     3. In July 2000, the Company invested approximately $3.5 million in Series
C Preferred Stock of Broadband which are convertible into Broadband common
shares. The annual dividend of 8.0% per share is payable only if declared and is
not cumulative.

     4. As of August 1, 2000, the Company finalized an agreement with Wilson
Investors, LLC, an entity affiliated with William Wilson and certain other
former officers and employees of Cornerstone Properties, to form Wilson/Equity
Office, LLC for the purpose of providing (directly or indirectly) development
management services and acquiring, owning, operating and holding various
projects. The Company has a 49.9% interest in this limited liability company.

     5. On August 3, 2000, the Company and an unaffiliated party acquired a 45%
equity interest and a debt interest in an entity that owns 1301 Avenue of the
Americas, a 1.77 million square foot office building located in Midtown
Manhattan in New York. The Company's share of the total investment is
approximately $163.0 million. In addition, the Company and its joint venture
partner purchased options to acquire the remaining 55% equity interest over a
period of three and one-half to eight years at a value as described in the
option agreements.

     6. On August 7, 2000, the Operating Partnership issued $360 million of
unsecured notes due 2010 (the "$360 Million Notes") in an offering to
institutional investors (the "$360 Million Notes Offering"). The net proceeds
after discount and offering expenses were approximately $356.2 million and will
be used to repay amounts outstanding on the Term Loan. The $360 Million Notes
bear interest at a stated rate of 8.1% per annum and have an effective annual
rate of 8.2% per annum.

     7. In August 2000, the joint venture owner of One Post Office Square
refinanced the mortgage note secured by the property which matured on July 1,
2000. The principal amount of the new debt is $110 million due July 2005 and
bears interest at LIBOR plus 45 basis points. The Company purchased a 9.05%
LIBOR based interest rate cap, thereby capping the effective interest rate on
the mortgage note at 9.50% for three years. The Company assigned the cap to the
joint venture, of which the Company owns 50%, effectively capping the Company's
share of the interest expense.

RESULTS OF OPERATIONS

  GENERAL

     The following discussion is based primarily on the Consolidated Financial
Statements of the Company as of June 30, 2000 and December 31, 1999 and for the
three and six months ended June 30, 2000 and 1999.

Properties, including reimbursements from tenants for certain operating costs,
and from parking revenue from Office Properties and Parking Facilities.

     Below is a summary of the Company's acquisition and disposition activity
since January 1, 1999. The buildings and total square feet shown include
Properties the Company owns in joint ventures with other partners and reflects
the total square footage of the Properties. Excluding the joint venture

    and included in the number of parking facilities owned by the Company.
    Effective with the second quarter of 1999, this garage is no longer
    considered a stand-alone parking facility.

     As a result of the acquisition and disposition of properties, the financial
data presented shows changes in revenues and expenses from period-to-period.
Therefore, the Company does not believe its period to period financial data
necessarily are comparable. The following analysis shows changes resulting from
Properties that were held during the entire period for the periods being
compared (the "Core Portfolio") and the changes in the Total Portfolio.

     As reflected in the tables below, property revenues include rental
revenues, reimbursements from tenants for certain expenses, parking revenue and
other property operating revenues. Property operating expenses include real
estate taxes, insurance, repairs and maintenance and other property operating
expenses.

</TABLE>

  Property Revenues

     The increase in property revenues in the Core Portfolio resulted from an
increase in rental rates and an increase in occupancy. The weighted average
occupancy of the Core Portfolio increased from 94.2% at April 1, 1999 to 94.8%
at June 30, 2000. This increase represents approximately 0.7 million square feet
in the Core Portfolio between April 1, 1999 and June 30, 2000. Included in
Property Revenues are lease termination fees. These fees relate to specific
tenants who have paid a fee to terminate their lease obligations before the end
of the contractual term of their lease. Although the Company has received these
fees in the past, a prediction of the timing or amounts of future fees cannot be
made.

  Interest/Dividend Income

     Total Portfolio interest/dividend income increased as a result of the
Company's $73.9 million investment in a Tranche B note as part of the Sun
America Center debt restructuring in September 1999. The Company's share of the
face amount of the Tranche B note is approximately $136.0 million and the note
matures on August 31, 2014. The note accrues interest at a stated rate of 7.25%
per annum. The Company also earned dividend revenue from its $75 million
investment in Series A Convertible Preferred Stock of HG Global Workplaces, Inc.
in May 2000 which has an initial dividend rate of 13.5% per annum and increases
by 50 basis

                                       22
<PAGE>   23

points each year through maturity in 2007. The Company also earned interest
income from property disposition proceeds held in escrow accounts. The amounts
in escrow will be utilized for property acquisitions or returned to the Company.

  Interest Expense

     Total Portfolio interest expense increased from the prior period as a
result of having a higher average outstanding debt balance as compared to the
prior period and an increase in the weighted average interest rate. In addition,
the following statistics for each period for the Total Portfolio are as follows:

     - Total debt to total assets increased to 46.1% from 42.2%;

     - Interest coverage ratio remained stable at 2.9 times; and

     - Weighted average interest rate increased to 7.5% from 7.0%.

     Core Portfolio interest expense decreased from the prior period due to the
paydown of mortgage debt on certain Properties. Interest expense on the
unsecured notes and the lines of credit is not reflected in the Core Portfolio.

  Depreciation and Amortization

     Total Portfolio depreciation and amortization expense increased from the
prior period as a result of Properties acquired and capital and tenant
improvements made during the periods. Core Portfolio depreciation and
amortization expense increased as a result of capital and tenant improvements.

  Property Operating Expenses

     Core Portfolio property operating expenses increased mainly as a result of
real estate taxes and other operating expenses. Real estate taxes increased
approximately $3.7 million due to higher property tax assessments and other
operating expenses increased approximately $8.1 million primarily due to higher
repairs and maintenance costs and general property operating expenses.

  General and Administrative Expenses

     General and administrative expenses increased due to an increase in the
number of employees at the corporate office as a result of the establishment of
new revenue-producing business groups such as Access and the hiring of
additional personnel in other corporate groups, primarily the information
technology group. Although general and administrative expenses are expected to
increase along with any increase in the size of the Company's portfolio, it is
also anticipated that the Company will realize economies of scale with future
growth, should it occur.

  Income from Investment in Unconsolidated Joint Ventures

     Income from investment in unconsolidated joint ventures increased for the
Total Portfolio due to the partial sale of twelve Office Properties in December
1999 and one Office Property in June 2000. The Company retained an equity
interest in these Office Properties and accounts for its remaining interest
under the equity method of accounting. Prior to the sale, the Company
consolidated the results of operations of such Office Properties.

increase in rental rates partially offset by a decrease in occupancy. The
weighted average occupancy of the Core Portfolio decreased from 95.3% at January
1, 1999 to 94.8% at June 30, 2000. Included in Property Revenues are lease
termination fees. These fees relate to specific tenants who have paid a fee to

  Income from Investment in Unconsolidated Joint Ventures

     Income from investment in unconsolidated joint ventures increased for the
Total Portfolio due to the partial sale of twelve Office Properties in December
1999 and one Office Property in June 2000. The Company retained an equity
interest in these Office Properties and accounts for its remaining interest
under the equity method of accounting. Prior to the sale, the Company
consolidated the results of operations of such Office Properties.

LIQUIDITY AND CAPITAL RESOURCES

  Liquidity

     Net cash provided from operations represents the primary source of
liquidity to fund distributions, debt service, recurring capital costs and
non-revenue enhancing tenant improvements. In order to qualify as a REIT for
federal income tax purposes, the Company must distribute at least 95% of its
REIT taxable income (excluding capital gains). Accordingly, the Company
currently intends to continue to make, but has not contractually bound itself to
make, regular quarterly distributions to holders of Common Shares/Units and
preferred shares. Subject to the foregoing, the Company has established annual
distribution rates as follows:

     - $1.68 per annum per Common Share/Unit;

     - 8.98% per annum ($2.245 per share) for each Series A Preferred Share;

     - 5.25% per annum ($2.625 per share) for each Series B Preferred Share; and

     - 8.625% per annum ($2.15625 per share) for each Series C Preferred Share.

     The Company intends to continue to fund distributions, debt service,
recurring capital costs and non-revenue enhancing tenant improvements from cash
from operations and borrowings under its credit facilities. The Company also
expects that its unsecured credit facilities will provide for temporary working
capital, the funding of capital improvements and revenue enhancing tenant
improvements, unanticipated cash needs and funding of acquisitions and
development costs.

     Since the anticipated size of the Company's distributions will not allow
the Company, using only cash from operations, to retire all of its debt as it
comes due, the Company will be required to repay maturing debt with funds from
debt and/or equity financing. There can be no assurance that such financing will
be available on acceptable terms.

  Debt Financing

     The table below summarizes the mortgage debt, unsecured notes and lines of
credit indebtedness outstanding at June 30, 2000 and December 31, 1999,
including a net unamortized (discount)/premium on mortgage debt of $(20,383) and
$10,574, respectively, and a net unamortized (discount)/premium on unsecured
notes of $(508) and $47, respectively, recorded in connection with property
acquisitions, mergers and the issuance of unsecured notes.

     The instruments encumbering the Properties restrict transfer of the
respective Properties subject to the terms of the mortgage, prohibit additional
liens and require payment of real estate taxes on the Properties, maintenance of
the Properties in good condition, maintenance of insurance on the Properties and
obtaining lender consent to material tenant leases..

CREDIT FACILITIES

     The cash portion of the Cornerstone Merger of approximately $1.2 billion
was partially funded from the $1.0 Billion Credit Facility and a new revolving
credit facility. Concurrently with the merger, the Company fully borrowed $1.0
billion under the $1.0 Billion Credit Facility and amended the facility into a
term loan (the "Term Loan"). The Term Loan bears interest at LIBOR plus 80 basis
points and matures on May 29, 2001. If the Company obtains net proceeds from the
disposition of a Property (excluding proceeds from a tax-deferred property
disposition), the issuance of unsecured notes or the issuance of Common
Shares/Units the net proceeds must be used to repay any amounts outstanding
under the Term Loan up to the then current unpaid balance of the Term Loan.

     The remaining cash consideration of the Cornerstone Merger was funded from
a new $1.0 billion revolving credit facility obtained at the time of the merger
(the "Line of Credit"). The Line of Credit bears interest at LIBOR plus 60 basis
points and matures on June 19, 2003. There is also a facility fee of $2.0
million per annum on the Line of Credit payable quarterly. In addition, the
Company assumed interest rate protection agreements in the notional amount of
$250 million effectively converting a portion of the Line of Credit to a
fixed-blended interest rate of 4.6%. The interest rate protection agreements
terminate in December 2000 and January 2001.

     On April 10, 2000, the Company repaid the Chase Term Loan in the amount of
$100 million with proceeds from the $1.0 Billion Credit Facility.

CORNERSTONE MERGER

     On June 19, 2000, the Company, the Operating Partnership, Cornerstone
Properties Inc. ("Cornerstone") and Cornerstone Properties Limited Partnership
("Cornerstone Partnership") consummated the merger of Cornerstone with and into
the Company and Cornerstone Partnership with and into the Operating Partnership
(the "Cornerstone Merger") at a cost of approximately $4.5 billion. The purchase
price consisted of:

          (i) the Company's issuance of approximately 51.3 million Common Shares
     valued at $24.68 per share and the issuance of stock options for a total of
     approximately $1,271.3 million;

          (ii) the Operating Partnership's issuance of approximately 12.4
     million Units to third parties valued at $24.68 per Unit for a total of
     approximately $306.0 million;

          (iii) the cash redemption of approximately 58.6 million Cornerstone
     common shares valued at $18.00 per share for a total of approximately
     $1,053.9 million;

          (iv) the cash redemption of approximately 3.0 million Cornerstone
     preferred shares valued at $18.00 per share for a total of approximately
     $57.6 million, plus accrued but unpaid dividends;

          (v) the assumption of approximately $1,304.9 million of secured debt
     and $415.5 million of unsecured debt;

          (vi) the payment of merger costs of approximately $72.1 million; and

          (vii) the assumption of net liabilities of approximately $9.6 million.

     The cash portion of the Cornerstone Merger of approximately $1.2 billion
was partially funded from the $1.0 Billion Credit Facility and a new revolving
credit facility. See Credit Facilities above for further disclosure.

MARKET RISK

     Since December 31, 1999, there have been no material changes in the
information regarding market risk that was provided in the Company's Form 10-K
for the year ended December 31, 1999.

CAPITAL IMPROVEMENTS

     The following capital improvements, tenant improvements and leasing
commission information excludes the properties acquired in the Cornerstone
Merger since the merger date was June 19, 2000.

     The Company considers capital improvements and revenue enhancing tenant
improvements when a property is acquired in determining the amount of equity and
debt financing required to purchase the property and fund the improvements.
Therefore, capital improvements made in the year of acquisition and the
following two years, are treated separately from typical recurring capital
expenditures, non-revenue enhancing tenant improvements and leasing commissions
required once these properties have reached stabilized occupancy, and deferred
maintenance and renovations planned at the time of acquisition have been
completed. Capital improvements (including tenant improvements and leasing
commissions for shell space) for the six months ended June 30, 2000 were
approximately $17.8 million or $0.23 per square foot. These amounts exclude
capital and tenant improvements of approximately $48.7 million for developments.

     The Company considers capital expenditures to be recurring expenditures
relating to the ongoing maintenance of the Office Properties. The table below
summarizes capital expenditures for the six months ended June 30, 2000. The
capital expenditures set forth below are not necessarily indicative of future
capital expenditures.

TENANT IMPROVEMENTS AND LEASING COMMISSION COSTS

     The Company distinguishes its tenant improvements and leasing commissions
between those that are revenue enhancing (i.e., required for space which is
vacant at the time of acquisition or that has been vacant for nine months or
more) and non-revenue enhancing (i.e., required to maintain the revenue being
generated from currently leased space). The table below summarizes the revenue
enhancing and non-revenue enhancing tenant improvements and leasing commissions
for the six months ended June 30, 2000. The tenant improvement and leasing
commission costs set forth below are presented on an aggregate basis and do not
reflect significant regional variations and, in any event, are not necessarily
indicative of future tenant improvements and leasing commission costs:

(a) The Estimated Placed in Service Date represents the date the certificate of
    occupancy has been or is anticipated to be obtained. Subsequent to obtaining
    the certificate of occupancy, the property will undergo a lease-up period.
    The Total Estimated Costs include amounts attributable to tenanting the
    Property. These numbers are estimates and may be subject to change upon
    completion of the development.

(b) The Company expects to acquire this property in August 2000. This
    transaction is contingent upon certain terms and conditions as set forth in
    its purchase agreement. There can be no assurance that this transaction will
    be consummated.

(c) These joint ventures were acquired in the Cornerstone Merger and are in
    various stages of development or pre-development. The Company is currently
    evaluating these developments including the participation of additional
    joint venture partners and potential construction financing. With the
    exception of First and Howard (which is subject to certain third party
    conditions not under control of the Company), the Company's Board of
    Trustees has not yet approved these developments. The Total Estimated Costs
    (which represent 100% of the total development cost) shown are preliminary
    and, along with the Estimated Placed in Service Date, are subject to
    numerous factors over which the Company may have little or no control. There
    can be no assurance that these developments will be commenced or completed.

     In addition to the properties described above, the Company owns various
land parcels available for development. However, no significant development
activity is taking place on these sites at this time.

INFLATION

     Substantially all of the office leases require the tenant to pay, as
additional rent, a portion of any increases in real estate taxes (except, in the
case of certain California leases, which limit the ability of the landlord to
pass through to the tenants the effect of increased real estate taxes
attributable to a sale of real property interests) and operating expenses over a
base amount. In addition, many of the office leases provide for fixed increases
in base rent or indexed escalations (based on the Consumer Price Index or other
measures). The Company believes that inflationary increases in expenses will be
offset, in part, by the expense reimbursements and contractual rent increases
described above.

FUNDS FROM OPERATIONS

     Management of the Company believes Funds from Operations, as defined by the
National Association of Real Estate Investment Trusts, Inc. ("NAREIT"), to be an
appropriate measure of performance for an equity REIT. While Funds from
Operations is a relevant and widely used measure of operating performance of
equity REITs, it does not represent cash flow from operations or net income as
defined by generally accepted accounting principles ("GAAP"), and it should not
be considered as an alternative to these indicators in evaluating liquidity or
operating performance of the Company.

     The following table reflects the calculation of the Company's Funds from
Operations for the three and six months ended June 30, 2000 and 1999 on an
historical basis:

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

(1) The White Paper on Funds from Operations approved by the Board of Governors
    of the National Association of Real Estate Investment Trusts ("NAREIT") in
    March 1995 defines Funds from Operations as net income (loss) (computed in
    accordance with GAAP), excluding gains (or losses) from debt restructuring
    and sales of properties, plus real estate related depreciation and
    amortization and after adjustments for unconsolidated partnerships and joint
    ventures. In November 1999, NAREIT issued a National Policy Bulletin
    effective January 1, 2000 clarifying the definition of FFO to include all
    operating results, both recurring and non-recurring, except those defined as
    extraordinary under GAAP. In accordance with this NAREIT Bulletin, the
    Company will no longer adjust for the amortization of discounts and premiums
    on mortgages when calculating FFO. Accordingly, the Company restated the
    prior period data for comparative purposes. The Company believes that Funds
    from Operations is helpful to investors as a measure of the performance of
    an equity REIT because, along with cash flow from operating activities,
    financing activities and investing activities, it provides investors with an
    indication of the ability of the Company to incur and service debt, to make
    capital expenditures and to fund other cash needs. The Company computes
    Funds from Operations in accordance with standards established by NAREIT
    which may not be comparable to Funds from Operations reported by other REITs
    that do not define the term in accordance with the current NAREIT definition
    or that interpret the current NAREIT definition differently than the
    Company. Funds from Operations does not represent cash generated from
    operating activities in accordance with GAAP, nor does it represent cash
    available to pay distributions and should not be considered as an
    alternative to net income (determined in accordance with GAAP) as an
    indication of the Company's financial performance or to cash flow from
    operating activities (determined in accordance with GAAP) as a measure of
    the Company's liquidity, nor is it indicative of funds available to fund the
    Company's cash needs, including its ability to make cash distributions.

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

     On May 4, 2000, the Company held its 2000 annual meeting of shareholders.
The 2000 annual meeting was called for the following purposes: (1) to elect two
trustees of the Company to serve until the 2003 annual meeting of shareholders;
(2) to approve amendments to the Company's declaration of trust regarding voting
requirements for business combinations; (3) to approve an amendment to the
Company's bylaws regarding voting by electronic means; and (4) to transact such
other business as may properly come before the meeting or any adjournment or
postponement thereof.

     The following table sets both the names of the trustees elected at the 2000
annual meeting for new three-year terms and the number of votes cast for and
withheld for each trustee:
