ITEM 1.  BUSINESS.

                                 EQUITY OFFICE

     As used herein, the terms "we," "us," "our," or "Equity Office" refer to
Equity Office Properties Trust, a Maryland real estate investment trust,
individually or together with its subsidiaries, including EOP Operating Limited
Partnership, a Delaware limited partnership (sometimes referred to as "EOP
Partnership"), and our predecessors. With EOP Partnership, we were formed as a
REIT to continue and expand the national office property business organized by
Mr. Samuel Zell, our Chairman of the Board, and to complete the consolidation of
our predecessors. We completed our initial public offering, or "IPO," on July
11, 1997. We are a fully integrated, self-managed real estate company engaged in
acquiring, owning, managing, developing and leasing office properties. We have
elected to be taxed as a real estate investment trust, or "REIT," for federal
income tax purposes and generally will not be subject to federal income tax if
we distribute 100% of our taxable income and comply with a number of
organizational and operational requirements.

     As of December 31, 2000, we owned or had an interest in 381 office
properties containing approximately 99.0 million rentable square feet of office
space (the "Office Properties") and owned nine stand-alone parking facilities
containing approximately 14,244 parking spaces (the "Parking Facilities" and,
together with the Office Properties, the "Properties"). The weighted average
occupancy for the Office Properties at December 31, 2000 was approximately
94.6%. The Office Properties are located in 104 submarkets in 37 markets in 24
states and the District of Columbia. The Office Properties, by rentable square
feet, are located approximately 51.3% in central business districts ("CBDs") and
48.7% in suburban markets. We own substantially all of our assets and conduct
substantially all of our operations through EOP Partnership. We owned
approximately 87.9% of EOP Partnership as of December 31, 2000 and are its sole
general partner.

     Our executive offices are located at Two North Riverside Plaza, Suite 2100,
Chicago, Illinois 60606, and our telephone number is (312) 466-3300.

                              ACQUISITION ACTIVITY

     Since the IPO, we have invested approximately $13.9 billion, calculated on
a cost basis, in acquisitions of institutional quality office properties and
parking facilities throughout the United States. During the year ended December
31, 2000, we completed several acquisitions, including Cornerstone Properties
Inc. and its operating partnership subsidiary, in which we acquired 85 office
properties containing an aggregate of approximately 21.0 million square feet of
rentable space and several vacant land parcels. The aggregate consideration we
paid for these acquisitions during 2000 was approximately $4.9 billion,
comprised of $1.5 billion in cash, $1.6 billion in Equity Office common shares
and units of limited partnership interest in EOP Partnership and $1.8 billion in
assumed liabilities.

                               CORNERSTONE MERGER

     On June 19, 2000, we completed the merger of Cornerstone Properties Limited
Partnership ("Cornerstone Partnership") with and into EOP Partnership and the
merger of Cornerstone Properties Inc. ("Cornerstone") with and into Equity
Office (collectively, the "Cornerstone Merger") at a total cost of approximately
$4.5 billion comprised of the issuance of Equity Office Common Shares and
options, EOP Partnership Units, the assumption of debt and assumed liabilities
and cash. The cash portion of the Cornerstone Merger of approximately $1.2
billion was funded from EOP Partnership's credit facilities. As a result of the
Cornerstone Merger, Equity Office acquired an interest in 82 Office Properties
containing approximately 18.9 million square feet of office space.

                  PENDING MERGER WITH SPIEKER PROPERTIES, INC.

     In February 2001, Equity Office and Spieker Properties, Inc. ("Spieker")
entered into a merger agreement in which Spieker will merge into Equity Office
and EOP Partnership will acquire Spieker Properties, L.P., Spieker's operating
partnership subsidiary (the "Spieker Merger"). The transaction values Spieker
(including the outside interests in Spieker Properties, L.P.) at approximately
$7.2 billion, which includes transaction costs and the assumption of
approximately $2.1 billion in debt and $431 million in preferred stock and
partnership units. Equity Office will pay approximately $1.085 billion in cash
and issue approximately 118.6 million new Equity Office common shares and EOP
Partnership units and 14.3 million new Equity Office preferred shares in the
transaction. We intend to finance the $1.085 billion cash portion of the
purchase price using a combination of available borrowing capacity under our
existing Credit Facility, and a new bridge loan facility to be entered into
before the closing of the merger and/or through the issuance by EOP Partnership
of senior unsecured notes.

     Following the merger, Equity Office will own and operate 616 office
buildings consisting of 124 million square feet of office space nationwide,
including 25 million square feet of office space attributable to Spieker. Equity
Office will also acquire Spieker's industrial portfolio of approximately 13.5
million square feet and its development properties totaling 1.7 million square
feet.

     Upon completion of the merger, Equity Office will expand its Board of
Trustees from 13 to 16 members. The new members will be Warren E. Spieker, Jr.,
chairman of Spieker, and Co-Chief Executive Officers Craig G. Vought and John A.
Foster.

     The merger is intended to qualify as a tax-free reorganization at the
corporate level for federal income tax purposes, with Spieker stockholders
recognizing taxable income only up to the amount of cash received in the merger.
The closing of the transaction is conditioned upon each party receiving an
acceptable tax opinion to that effect. The merger, which will be accounted for
using purchase accounting, is subject to the approval of the shareholders of
both companies and to other customary conditions.

                         BUSINESS AND GROWTH STRATEGIES

     Our primary business objective is to achieve sustainable long-term growth
in cash flow and portfolio value in order to maximize shareholder value. We
intend to achieve this objective by owning and operating high-quality office
buildings and providing a superior level of service to tenants across the United
States. We plan on supplementing this strategy through Access, a strategic
business service unit that provides customers access to various business
products and services.

     INTERNAL GROWTH.  We believe that our future internal growth will come
from:

          (a) tenant roll-over at increased rents where market conditions
     permit;

          (b) lease up of vacant space;

          (c) completion and lease-up of development properties;

                                        4
<PAGE>   5

          (d) recycling of capital through selective disposition of certain
     assets and reinvestment in properties or other assets consistent with our
     long term growth strategy;

          (e) ancillary revenues generated from providing business products and
     services to tenants through Access;

          (f) reduction of various expenses as a percentage of revenues; and

          (g) increased capital market efficiencies.

     As of December 31, 2000, 4.3 million rentable square feet of our office
property space was vacant. During the period from December 31, 2000 through
December 31, 2005, there are 6,088 leases for approximately 57.6 million
rentable square feet of space that are scheduled to expire. As of December 31,
2000, the average rent for this space was $26.83 per square foot. The actual
rental rates at which available space will be relet will depend on prevailing
market factors at the time.

     As of December 31, 2000, we have more than 2.7 million square feet of
projects in our development pipeline. We have continued to prudently pursue
projects with local development experts where customer need is evident and
market conditions warrant.

     In addition to our current development pipeline, we own various undeveloped
land parcels on which approximately seven million square feet of office space
could be developed, assuming our receipt of all-necessary permits, licenses and
approvals. Our policy is to develop land only when market conditions warrant.
Although we may develop some properties ourselves, a portion of this activity
may be conducted with joint venture partners.

     EXTERNAL GROWTH.  Assuming that capital is available to us on reasonable
terms, we expect to actively pursue, over the long term, acquisitions of
additional office properties. Properties may be acquired separately or as part
of a portfolio, and may be acquired for cash and/or in exchange for our equity
or debt securities. These acquisitions may be customary real estate
transactions, joint ventures, and/or mergers or other business combinations.

                                   EMPLOYEES

     As of December 31, 2000, we had approximately 2,061 employees providing
in-house expertise in:

     - property management;
     - Access and business development;
     - leasing;
     - finance;
     - tax;
     - acquisition;
     - development;
     - disposition;
     - marketing;
     - accounting;
     - information systems; and
     - law

     Our seven executive officers have an average tenure of 11.5 years with us
or our affiliates and an average of 22 years experience in the real estate
industry.

                                  COMPETITION

     The leasing of real estate is highly competitive. Equity Office's
properties compete for tenants with similar properties located in its markets
primarily on the basis of location, rent charged, services provided and the
design and condition of improvements. Equity Office also experiences competition
when attempting to acquire interests in desirable real estate, including
competition from domestic and foreign financial institutions, other REITs, life
insurance companies, pension trusts, trust funds, partnerships and individual
investors. In addition, Equity Office competes for acquisition of building sites
or redevelopment opportunities with domestic and foreign financial institutions,
other REITs, life insurance companies, pension trusts, trust funds, partnerships
and individual investors.

                               INDUSTRY SEGMENTS

     Equity Office's primary business is the ownership and operation of Office
Properties. Equity Office's long-term tenants are in a variety of businesses and
no single tenant is significant to Equity Office's business. Information related
to this segment for the years ended December 31, 2000, 1999 and 1998 is set
forth in note 18 to the consolidated financial statements that are part of this
report.

(1) The selected financial data has been derived from the historical
    consolidated or combined financial statements of Equity Office and Equity
    Office Predecessors, audited by Ernst & Young LLP, independent auditors.

(2) On June 19, 2000, Equity Office completed its acquisition of Cornerstone.
    See Item 1. Business -- Cornerstone Merger and Note 3 to Equity Office's
    consolidated financial statements included elsewhere herein.

(3) On December 19, 1997, Equity Office completed its acquisition of Beacon
    Properties Corporation and Beacon Partnership L.P. (the "Beacon Merger") at
    a cost of approximately $4.3 billion. As a result of the Beacon Merger,
    Equity Office acquired an interest in 130 Properties containing
    approximately 20.9 million square feet.

(4) Property operating expenses include real estate taxes, insurance, repairs
    and maintenance and other property operating expenses.

(5) 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 Funds from Operations
    to include all operating results, both recurring and non-recurring, except
    those defined as extraordinary under GAAP. In accordance with this NAREIT
    Bulletin, Equity Office no longer adjusts for the

                                        24
<PAGE>   25

    amortization of discounts and premiums on mortgages when calculating Funds
    from Operations. Accordingly, Equity Office restated the prior period data
    for comparative purposes. Equity Office 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 Equity Office to incur and service debt, to
    make capital expenditures and to fund other cash needs. Equity Office
    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 Equity Office. 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 Equity Office's financial performance or to cash
    flow from operating activities, determined in accordance with GAAP, as a
    measure of Equity Office's liquidity, nor is it indicative of funds
    available to fund Equity Office's cash needs, including its ability to make
    cash distributions. For a reconciliation of net income to Funds from
    Operations, see "Management's Discussion and Analysis of Financial Condition
    and Results of Operations -- Funds from Operations."

(6) Property net operating income is defined as rental income, including tenant
    reimbursements, parking and other income less property operating expenses,
    including real estate taxes, insurance, repairs and maintenance and other
    property operating expenses.

(7) Earnings before interest, taxes, depreciation and amortization is defined as
    net income excluding interest expense, taxes, depreciation and amortization,
    minority interest allocation with respect to EOP Partnership, net gain
    (loss) on sales of real estate, gains (losses) from extraordinary items and
    income from investment in unconsolidated joint ventures plus Equity Office's
    share of the earnings before interest, taxes, depreciation and amortization
    for the unconsolidated joint ventures. Earnings before interest, taxes,
    depreciation and amortization is presented because Equity Office believes
    this data is used by some investors to evaluate Equity Office's ability to
    meet debt service requirements. Equity Office considers earnings before
    interest, taxes, depreciation and amortization to be an indicative measure
    of its operating performance due to the significance of Equity Office's
    long-lived assets and because this data can be used to measure Equity
    Office's ability to service debt, fund capital expenditures and expand its
    business. However, this data should not be considered as an alternative to
    net income, operating profit, cash flows from operations or any other
    operating or liquidity performance measure prescribed by GAAP. In addition,
    earnings before interest, taxes, depreciation and amortization as calculated
    by Equity Office may not be comparable to similarly titled measures reported
    by other companies. Interest expense, taxes, depreciation and amortization,
    which are not reflected in the presentation of earnings before interest,
    taxes, depreciation and amortization, have been, and will be, incurred by
    Equity Office. Investors are cautioned that these excluded items are
    significant components in understanding and assessing Equity Office's
    financial performance.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS.

OVERVIEW

     The following discussion and analysis of the consolidated financial
condition and consolidated results of operations should be read together with
the consolidated financial statements of Equity Office and notes thereto
contained in this Form 10-K. Terms employed herein as defined terms, but without
definition, shall have the meaning set forth in the financial statements.
Statements contained in this "Management's Discussion and Analysis of Financial
Condition and Results of Operations," including, without limitation, the "Market
Risk" and "Developments" disclosures, which are not historical fact may be
forward-looking statements within the meaning of Section 21E of the Securities
Exchange Act of 1934 (the "Exchange Act"). Equity Office intends such
forward-looking statements to be covered by the safe harbor provisions for
forward-looking statements contained in Section 21E of the Exchange Act. Such
statements are subject to certain risks and uncertainties, which could cause
actual results to differ materially from those projected or anticipated. Readers
are cautioned not to place undue reliance on these forward-looking statements,
which speak only as of December 31, 2000. Among the factors that Equity Office
has made assumptions are the following:

     - Equity Office's ability to successively integrate Cornerstone's
       operations into those of Equity Office;
     - Future economic conditions which may have an impact upon the demand for
       office space and tenant ability to pay rent, either at current or at
       increased levels;
     - Prevailing interest rates;
     - The extent of any inflation on operating expenses;
     - Equity Office's ability to reduce various expenses as a percentage of
       revenues;
     - Equity Office's continuing ability to pay amounts due to its noteholders
       and preferred shareholders before any distribution to holders of Common
       Shares;
     - The cost to complete and lease-up pending developments;
     - Equity Office's continued access to adequate credit facilities or other
       debt financing on acceptable terms, including amounts required for the
       Spieker Merger; and
     - The demand from Equity Office's customers for office-related services.

     During the year ended December 31, 2000, Equity Office completed the
following key transactions:

     - Acquired Cornerstone (see "Cornerstone Merger" below for additional
       information);
     - Acquired through a joint venture a 45% general partner equity interest
       and a debt interest in a limited partnership that owns 1301 Avenue of the
       Americas, a 1.77 million square foot office building located in Midtown
       Manhattan in New York. Equity Office's share of this investment at
       closing was approximately $163.2 million;
     - Sold 11 parking facilities for approximately $180.0 million;
     - Sold seven office properties and a development parcel for approximately
       $146.4 million;
     - Sold a 49.9% interest in Bank of America Tower in Seattle for
       approximately $209.6 million;
     - Issued approximately $2.2 billion of unsecured notes in four separate
       offerings; and
     - Invested approximately $75 million in convertible preferred stock of HQ
       Global Workplaces, Inc. ("HQ"), a provider of temporary office suites.

CORNERSTONE MERGER

     On June 19, 2000, we completed the merger of Cornerstone Partnership with
and into EOP Partnership and the merger of Cornerstone with and into Equity
Office at a total cost of approximately $4.5 billion. The purchase price
consisted of:

          (a) Equity Office's issuance of approximately 51.2 million Common
     Shares valued at $24.68 per share and the assumption of approximately 3.7
     million share options, for a total of approximately $1,268.6 million;
          (b) EOP 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;

                                        26
<PAGE>   27

          (c) the cash redemption of approximately 58.5 million shares of
     Cornerstone common stock valued at $18.00 per share for a total of
     approximately $1,052.2 million;
          (d) the cash redemption of approximately 3.0 million shares of
     Cornerstone preferred stock valued at $18.00 per share, plus accrued but
     unpaid dividends, for a total of approximately $57.6 million;
          (e) the assumption of approximately $1,304.9 million of secured debt
     and $415.5 million of unsecured debt;
          (f) the payment of merger costs of approximately $82.9 million; and
          (g) the assumption of net liabilities of approximately $19.8 million.

     The cash portion of the Cornerstone Merger of approximately $1.2 billion
was funded from the $1.0 Billion Credit Facility and the Line of Credit. See
"Lines of Credit" for additional information.

SPIEKER MERGER

     In February 2001, Equity Office and Spieker Properties, Inc. ("Spieker")
entered into a merger agreement in which Spieker will merge into Equity Office
and EOP Partnership will acquire Spieker Properties, L.P., Spieker's operating
partnership subsidiary (the "Spieker Merger"). The transaction values Spieker
(including the outside interests in Spieker Properties, L.P.) at approximately
$7.2 billion, which includes transaction costs and the assumption of
approximately $2.1 billion in debt and $431 million in preferred stock and
partnership units. Equity Office will pay approximately $1.085 billion in cash
and issue approximately 118.6 million new Equity Office Common Shares and EOP
Partnership units and 14.3 million new Equity Office preferred shares in the
transaction. We intend to finance the $1.085 billion cash portion of the
purchase price using a combination of available borrowing capacity under our
existing Line of Credit and a new bridge loan facility to be entered into before
the closing of the merger and/or through the issuance of EOP Partnership of
senior unsecured notes.

     Following the merger, Equity Office is expected to own and operate 616
office buildings consisting of 124 million square feet of office space
nationwide, which includes 25 million square feet of office space attributable
to Spieker. Equity Office will also acquire Spieker's industrial portfolio of
approximately 13.5 million square feet and its development properties totaling
1.7 million square feet.

     Upon completion of the merger, Equity Office will expand its Board of
Trustees from 13 to 16 members. The new members will be Warren E. Spieker, Jr.,
chairman of Spieker, and Co-Chief Executive Officers Craig G. Vought and John A.
Foster.

     The merger is intended to qualify as a tax-free reorganization at the
corporate level for federal income tax purposes, with Spieker stockholders
recognizing taxable income only up to the amount of cash received in the merger.
The closing of the transaction is conditioned upon each party receiving an
acceptable tax opinion to that effect. The merger, which will be accounted for
using purchase accounting, is subject to the approval of the shareholders of
both companies and to other customary conditions.

RESULTS OF OPERATIONS

GENERAL

     The following discussion is based primarily on the consolidated financial
statements of Equity Office as of December 31, 2000 and 1999, and for the years
ended December 31, 2000, 1999 and 1998.

     Equity Office receives income primarily from rental revenue from the Office
Properties, including reimbursements from tenants for certain operating costs,
and from parking revenue from Office Properties and Parking Facilities.

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

                                        27
<PAGE>   28

the square feet of these Properties, Equity Office effectively owned 92.7
million square feet of office space as of December 31, 2000.

(1) The 601 Tchoupitoulas garage previously was considered a stand-alone garage
    and included in the number of Parking Facilities.

     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, Equity Office does not believe its period-to-period financial data
are necessarily 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,
Access services 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 partially offset by a decrease in occupancy. The
weighted average occupancy of the Core Portfolio decreased from 95.3% at January
1, 1999 to 94.4% at December 31, 2000, mainly due to tenant rollover at various
Properties. 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
Equity Office has historically experienced similar levels of such termination
fees, there is no way of predicting the timing or amounts of future lease
termination fees.

Interest/Dividend Income

     Total Portfolio interest/dividend income increased primarily as a result of
a $75 million investment in May 2000 in Series A Convertible Cumulative
Preferred Stock (the "Series A Preferred Stock") of HQ Global Workplaces, Inc.
("HQ"). The Series A Preferred Stock has an initial dividend rate of 13.5% per
annum, which increases by 50 basis points each year through maturity in 2007.
Interest/dividend income also

                                        29
<PAGE>   30

increased as a result of a $73.9 million investment in September 1999 in a
mezzanine-level debt position related to the SunAmerica Center office property.
Equity Office's share of the face amount of the note is approximately $136.0
million and bears interest at 7.25% and matures August 31, 2014. Equity Office
also earned interest from property disposition proceeds held in escrow accounts.
The amounts in escrow will be utilized for property acquisitions or returned to
Equity Office.

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, mainly as a result of the Cornerstone Merger, 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 46.8% from 41.7%;
     - Interest coverage ratio decreased to 2.7 times from 2.9 times; and
     - Weighted average interest rate increased to 7.5% from 7.2%.

     Core Portfolio interest expense decreased from the prior period due to the
paydown of mortgage debt on certain Properties partially offset by the financing
of Park Avenue Tower and 850 Third Avenue. Interest expense on unsecured notes
and the lines of credit are 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
made during the periods.

Property Operating Expenses

     Core Portfolio property operating expenses increased mainly as a result of
increases in real estate taxes and other operating expenses. Real estate taxes
increased approximately $11.9 million due to higher property tax assessments.
Other operating expenses increased approximately $21.7 million primarily due to
higher repairs and maintenance costs, increased utility costs and an increase in
expenses at certain properties that were under development.

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. In addition, general and administrative expenses increased as
a result of hiring additional personnel due to the Cornerstone Merger, which was
anticipated. Although general and administrative expenses are expected to
increase along with any increase in the size of the portfolio, it is also
anticipated that economies of scale will be realized 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 acquisition of an interest in 1301 Avenue of the
Americas office property in August 2000 and the partial sale of 12 Office
Properties in December 1999 and two Office Properties in June 2000. Equity
Office retained an equity interest in these Office Properties that were
partially sold and accounts for its remaining interests under the equity method
of accounting. Prior to the sale, the results of operations of such Office
Properties were consolidated.

                                        30
<PAGE>   31

Net Gain on Sales of Real Estate

     Net gain on sales of real estate decreased due to the combined gross sales
price in excess of book value at the time of disposition for the seven office
properties, 11 parking facilities and the partial sale of two Office Properties
in 2000 being less than the combined gross sales price in excess of book value
at the time of disposition for four office properties and the partial sale of 11
Office Properties in 1999.

Property Revenues

     The increase in property revenues in the Core Portfolio resulted from a
combination of occupancy and rental rate increases. The weighted average
occupancy of the Core Portfolio increased from 93.8% at January 1, 1998 to 94.6%
at December 31, 1999. This increase represents approximately .5 million square
feet of additional occupancy in the Core Portfolio.

     Property revenues for the Total Portfolio include lease termination fees of
approximately $15.9 million and $15.5 million for the years ended December 31,
1999 and 1998, respectively, and property revenues for the Core Portfolio
include lease termination fees of approximately $12.8 million and $14.0 million
for the years ended December 31, 1999 and 1998, respectively (lease termination
fees are included in the "other revenue" category on the consolidated statements
of operations). These fees relate to specific tenants who have paid a

                                        31
<PAGE>   32

fee to terminate their lease obligations before the end of the contractual term
of their lease. Although Equity Office has historically experienced similar
levels of such termination fees, there is no way of predicting the timing or
amounts of future lease termination fees.

     Property revenues for the Total Portfolio also include straight-line rent
adjustments of approximately $65.4 million and $68.1 million for the years ended
December 31, 1999 and 1998, respectively. Property revenues for the Core
Portfolio include straight-line rent adjustments of approximately $44.7 million
and $58.0 million for the years ended December 31, 1999 and 1998, respectively.

Interest Expense

     Total Portfolio interest expense increased from the prior period as a
result of having more debt outstanding primarily attributable to property
acquisitions. The following statistics for each period for the Total Portfolio
are as follows:

     - Total debt to total assets decreased to 41.7% from 42.3%;
     - Interest coverage ratio decreased to 2.9 times from 3.0 times; and
     - Weighted average interest rate increased to 7.2% from 7.1%.

     Core Portfolio interest expense decreased from the prior period due to the
paydown of mortgage debt with proceeds from various unsecured notes offerings
and borrowing on the lines of credit. 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 as a result
of Properties acquired and capital and tenant improvements made during 1999 and
1998. Core Portfolio depreciation and amortization expense increased as a result
of capital and tenant improvements made to the Properties.

Property Operating Expenses

     Core Portfolio property operating expenses increased due to an increase in
real estate tax expense of approximately $10.1 million due to higher property
tax assessments in certain markets and an increase in insurance expense. These
increases were partially offset by decreases in repairs and maintenance and
other property operating expenses.

General and Administrative Expenses

     General and administrative expenses increased due to increases in the size
of Equity Office's portfolio and additional expenses associated with being a
public company. During 1999, Equity Office made significant investments in its
information systems, including the hiring of additional personnel and
established a real estate services group. In addition, Equity Office incurred
severance costs during 1999 that were not incurred in 1998. While general and
administrative expenses are expected to continue to increase along with any
increase in the size of Equity Office's portfolio, it is also anticipated that
Equity Office 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. Equity Office retained an equity interest in the twelve Office Properties
and accounts for its remaining interest under the equity method of accounting.
Prior to the sale, Equity Office consolidated the results of operations of such
Office Properties.

(1) Amounts reflected for Access services include income from the following:
    Telecom, Adcom, ATMs, Book Fairs and Vending.

(2) Equity Office received common stock and/or warrants to purchase common stock
    for allowing companies that provide telecommunication and other services
    access to Equity Office properties. The securities received from these
    companies were recorded as deferred revenue at fair value at the time such
    securities were earned and are included in other liabilities on the balance
    sheet. The deferred revenue is being amortized into other income over the
    terms of the respective license agreements.

(3) Equity Office indirectly owns a 47.5% membership interest in this joint
    venture. The joint venture provides fully furnished offices under
    short-term, flexible rental agreements to prospective tenants seeking this
    type of office space.

PARKING OPERATIONS

     In May 2000 Equity Office disposed of 11 of its 20 Parking Facilities. The
financial condition and the results of operations of the remaining nine Parking
Facilities are not considered by management to be material to Equity Office's
consolidated results. Therefore, summary financial information for the Parking
Facilities for the year ended December 31, 2000 is not presented.

</TABLE>

LIQUIDITY AND CAPITAL RESOURCES

Liquidity

     Net cash from operations represents the primary source of liquidity to fund
distributions, debt service, recurring capital costs and non-revenue enhancing
tenant improvements. Equity Office expects that its Line of Credit 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. In order to qualify as a REIT for federal
income tax purposes, Equity Office must distribute annually at least 95% of its
REIT taxable income (excluding capital gains). For taxable years beginning after
December 31, 2000, this REIT distribution requirement will be 90%. Accordingly,
Equity Office currently intends to continue to make, but has not contractually
bound itself to make, regular quarterly distributions to holders of Common
Shares and preferred shares. Subject to the foregoing, Equity Office has
established annual distribution rates as follows:

     - $1.80 per annum per Common Share;
     - 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.

     Since Equity Office's anticipated distributions will not allow Equity
Office, using only cash from operations, to retire all of its debt as it comes
due, Equity Office 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 or at all.

Debt Financing

     The table below summarizes the mortgage debt, unsecured notes and lines of
credit indebtedness at December 31, 2000 and 1999, including a net unamortized
(discount)/premium on mortgage debt of $(17,825) and $10,574, respectively, and
a net unamortized (discount)/premium on unsecured notes of

MORTGAGE DEBT

     As of December 31, 2000, total mortgage debt (excluding Equity Office's
share of unconsolidated debt of approximately $834.1 million) consisted of
approximately $2.8 billion of fixed-rate debt with a weighted average interest
rate of approximately 7.8% and $133.5 million of variable rate debt based on
various spreads over LIBOR. Equity Office's mortgage debt at December 31, 2000

     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.

LINES OF CREDIT

     During 1999, Equity Office had a $1.0 billion revolving credit facility
(the "$1.0 Billion Credit Facility"). The interest rate was based on Equity
Office's investment grade rating on its unsecured debt and was at LIBOR plus 60
basis points with a facility fee, based on the aggregate amount of the facility,
equal to 20 basis points per annum.

     When the Cornerstone Merger was completed, the cash portion of the merger
consideration of approximately $1.2 billion was funded from the $1.0 Billion
Credit Facility and a new $1.0 billion revolving

                                        36
<PAGE>   37

credit facility obtained in May 2000 (the "Line of Credit"). Concurrently with
the Cornerstone Merger, Equity Office borrowed $1.0 billion under the $1.0
Billion Credit Facility and amended this facility into a term loan (the "Term
Loan"). Interest on the Term Loan was based on LIBOR plus 80 basis points and
was scheduled to mature on May 29, 2001. In November 2000, Equity Office repaid
the Term Loan and terminated the loan agreement. As a result, Equity Office
incurred an extraordinary loss of $.9 million representing unamortized deferred
loan costs.

     The remaining cash consideration in the Cornerstone Merger was funded under
the Line of Credit, which bears interest at LIBOR plus 60 basis points and
matures on June 19, 2003. There is also an annual facility fee of $2.0 million
payable quarterly. In addition, a competitive bid option, whereby the lenders
participating in the credit facility bid on the interest rate to be charged, is
available for up to $350 million of the borrowings under the credit facility. In
addition, as part of the Cornerstone Merger, Equity Office assumed interest rate
protection agreements in the notional amount of $250 million ($185 million
terminated in December 2000 and the remaining interest rate protection
agreements terminated in January 2001). These interest rate protection
agreements effectively converted a portion of the Line of Credit to a
fixed-blended interest rate of 4.6% during the term of the protection
agreements. As of March 16, 2001, there was $76.0 million outstanding on the
Line of Credit.

     In January 2000, Equity Office obtained an additional unsecured borrowing
facility from the Chase Manhattan Bank for short-term borrowings not to exceed
$300 million in the aggregate. Upon request of Equity Office, and at the
lender's option, the lender may offer to lend funds at mutually agreed upon
interest rates and terms, as determined by current market condition. In April
2000, this term loan was repaid in the amount of $100 million with proceeds from
the $1.0 Billion Credit Facility and the agreement was terminated.

(1) Includes the cost of terminated interest rate protection agreements,
    offering and transaction costs and premiums and discounts on certain
    unsecured notes.
(2) The notes are subject to mandatory redemption and a remarketing agreement in
    2002 but do not mature until 2012.
(3) These notes are exchangeable into Common Shares at an exchange price of
    $34.00 per share, which is equal to an exchange rate of 29.4118 Common
    Shares per $1,000 principal amount of notes. If the closing price of a
    Common Share on the NYSE at the time a holder exercises its exchange right
    is less than the exchange price of $34.00, the holder will receive, in lieu
    of Common Shares, cash in an amount equal to 97% of the product of: (a) the
    number of Common Shares into which the principal amount of notes subject to
    such exercise would otherwise be exchangeable; and (b) such closing price
    per Common Share. The notes were issued by EOP Partnership and are
    guaranteed by Equity Office.

     EOP Partnership previously filed a shelf registration statement, which was
declared effective on July 22, 1998, relating to the issuance from time to time
of up to $2.0 billion of unsecured debt securities and warrants exercisable for
debt securities in amounts, at initial prices and on terms to be determined at
the time of the offering. In August 2000, EOP Partnership registered an
additional $60 million of unsecured notes under this registration statement in
connection with the issuance of $360 million of senior exchangeable notes
guaranteed as to principal and interest by Equity Office. EOP Partnership has
issued a total of $2.06 billion of unsecured notes under the registration
statement, of which $860 million were issued in 2000. Net proceeds from the
issuance and sale of notes in 2000 were used to pay down balances from time to
time outstanding under the Term Loan.

     EOP Partnership filed a shelf registration statement, which was declared
effective by the SEC on August 31, 2000, relating to the issuance from time to
time of up to an additional $2.0 billion of unsecured debt securities and
warrants exercisable for debt securities in amounts, at initial prices and on
terms to be determined at the time of the offering. In November 2000, EOP
Partnership issued $1.0 billion of unsecured notes under this registration
statement. The net proceeds from this offering were used to pay down the Term
Loan and the Line of Credit.

RESTRICTIONS AND COVENANTS

     Agreements or instruments relating to the unsecured notes and lines of
credit contain certain restrictions and requirements regarding total
debt-to-assets ratios, secured debt-to-total assets ratios, debt service
coverage ratios, minimum ratio of unencumbered assets to unsecured debt and
other limitations.

MARKET RISK

QUALITATIVE INFORMATION ABOUT MARKET RISK

     Equity Office's future earnings, cash flows and fair values relevant to
financial instruments are dependent upon prevalent market rates. Market risk is
the risk of loss from adverse changes in market prices and interest rates.
Equity Office manages its market risk by matching projected cash inflows from
operating, investing and financing activities with projected cash outflows to
fund debt service, acquisitions, capital expenditures, distributions to
shareholders and unitholders and other cash requirements. The majority of Equity
Office's outstanding debt (maturing at various times through 2029) has a fixed
interest rate, which minimizes the risk of fluctuating interest rates. Equity
Office utilizes certain derivative financial instruments at times to limit
interest rate risk. Interest rate protection agreements are used to convert
variable rate debt to a fixed rate basis or to hedge anticipated financing
transactions. Derivatives are used for hedging purposes rather than speculation.
Equity Office does not enter into financial instruments for trading purposes.

QUANTITATIVE INFORMATION ABOUT MARKET RISK

Interest Rate Risk

     As of December 31, 2000, total outstanding debt was approximately $8.8
billion, of which approximately $184.5 million, or 2.1%, is variable rate debt.
If market rates of interest on the variable rate debt increase by 10% (or
approximately 76 basis points), the increase in interest expense on the variable
rate debt would decrease future earnings and cash flows by approximately $1.4
million annually. If market rates of interest increased by 10%, the fair value
of the total outstanding debt would decrease by approximately $84.1 million. If
market rates of interest on the variable rate debt decrease by 10% (or
approximately 76 basis points), the decrease in interest expense on the variable
rate debt would increase future earnings and cash flows by approximately $1.4
million annually. If market rates of interest decrease by 10%, the fair value of
the total outstanding debt would increase by approximately $85.8 million.

     As of December 31, 1999, total outstanding debt was approximately $5.9
billion, of which approximately $.6 billion, or 10%, was variable rate debt. If
market rates of interest on the variable rate debt increased by 10% (or
approximately 74 basis points), the increase in interest expense on the variable
rate debt would have decreased future earnings and cash flows by approximately
$4.3 million. If market rates of interest increased by 10%, the fair value of
the total outstanding debt would have decreased by approximately $157.1 million.
If market rates of interest on the variable rate debt decreased by 10% (or
approximately 74 basis points), the decrease in interest expense on the variable
rate debt would have increased future earnings and cash flows by approximately
$4.3 million. If market rates of interest decreased by 10%, the fair value of
the total outstanding debt would have increased by approximately $166.2 million.

Market Rate Risk

     At December 31, 2000, Equity Office had put option agreements outstanding
in connection with the acquisition of certain properties in 1997 from Wright
Runstad & Company. On August 12, 1999, Equity Office and the holders of the
Wright Runstad & Company options (the "WR Holders") amended their put option
agreement to defer to August 13, 2000 (or to August 13, 2001 at the option of
the WR Holders) the exercise date for 1,717,844 of the 3,435,688 Common Shares
affected by the put option agreement (a maximum exposure to Equity Office of
approximately $54.1 million when and if this put option is exercised). Equity
Office and the WR Holders also agreed to cancel the put option on the remaining
1,717,844 Common Shares in exchange for Equity Office's payment to the WR
Holders of approximately $11.3 million on September 13, 1999. The payment
represented the excess of $31.50 over $24.90 (the average price of a Common
Share calculated over the five trading days immediately prior to August 13,
1999), for each of the 1,717,844 Common Shares affected by the put option
agreement. The portion of the amounts paid in excess of $29.10625 per Common
Share totaling approximately $4.1 million was reflected as a preferred
distribution. The remaining $7.2 million of the payment was recorded as a
reduction to shareholders' equity.

                                        39
<PAGE>   40

     The WR Holders exercised their option to extend the date to August 13,
2001, at which time the WR Holders can require Equity Office 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 Equity Office is obligated to pay to the WR Holders for each
Common Share sold at such lower price an amount equal to the difference between
$29.10625 and such lower price, not to exceed $3.00 per Common Share. Any
amounts paid by Equity Office as a result of such sales will be recorded as a
reduction in shareholders' equity. For put options exercised on August 13, 2001,
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 Shares (not to exceed $2.39375 per Common Share up to an
aggregate of approximately $4.1 million) will be reflected as a put option
settlement. The $4.1 million portion of the total potential payment has been
reflected as a put option settlement on a straight-line basis over the period
between August 13, 1999 and August 13, 2000.

     Equity Office's cash flows could decrease by up to $5.2 million if, prior
to August 13, 2001, the WR Holders sell all their Common Shares to third
parties. Cash flows may decrease by up to approximately $54.1 million if the WR
Holders exercise their rights under the put option agreement on August 13, 2001.
There will be no impact on cash flows from this transaction if the put option is
not exercised.

     Equity Office has several investments in marketable securities. If the
market price of these securities increases or decreases by 10%, Equity Office's
investment in the securities would increase or decrease by approximately $.7
million. Changes in the market prices of these securities are required to be
reflected as a corresponding adjustment to accumulated other comprehensive
income. At December 31, 2000, Equity Office had an unrealized holding loss on
these investments totaling approximately $28.3 million, which is reflected as
accumulated other comprehensive (loss) income. This compares to an unrealized
holding gain of $10.9 million at December 31, 1999. There will be no impact on
earnings or cash flows of Equity Office from market price fluctuations unless
Equity Office disposes of these investments or writes-down the investments upon
the determination that these investments have suffered a permanent impairment.

     Interest and market risk amounts were determined by considering the impact
of hypothetical interest rates and equity prices on Equity Office's financial
instruments. These analyses do not consider the effect of the reduced level of
overall economic activity that could exist in such an environment. Further, in
the event of a change of such magnitude, management would likely take actions to
further mitigate its exposure to the change. However, due to the uncertainty of
the specific actions that would be taken and their possible effects, these
analyses assume no changes in Equity Office's financial structure.

CAPITAL EXPENDITURES AND TENANT IMPROVEMENTS

     Capital expenditures are categorized as follows:

          - Non-recurring capital improvements -- capital improvements completed
     in the year of acquisition and the following two years (which were planned
     at the time of acquisition) and major renovations that enhance the value of
     the property;
          - Recurring capital expenditures -- capital improvements incurred that
     enhance the value of the Property that are not classified as non-recurring
     capital improvements;
          - Development costs -- all hard and soft costs associated with the
     development or redevelopment of a Property, including tenant improvements,
     leasing commissions and capitalized interest and operating costs until the
     Property is substantially complete and ready for its intended use;
          - Revenue enhancing tenant improvements and leasing
     commissions -- tenant improvements and leasing commissions incurred on
     space which is vacant at the time of acquisition or has been vacant for
     nine months or more; and
          - Non-revenue enhancing tenant improvements and leasing
     commissions -- tenant improvements and leasing commissions incurred in
     connection with the renewal or retenanting of currently leased space to
     maintain the revenue being generated by such space.

     The table below details the amounts incurred for each type of expenditure:

DEVELOPMENTS

     Equity Office currently owns several Properties in various stages of
development or pre-development. These developments are funded with proceeds from
working capital and the credit facility. Specifically identifiable direct
acquisition, development and construction costs are capitalized including, where
applicable, salaries and related costs, real estate taxes, interest and certain
pre-construction costs essential to the development of a property. The
Properties under development as of December 31, 2000 are as follows:

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

(1) The Estimated Placed in Service Date represents the date the certificate of
    occupancy has been or is currently anticipated to be obtained. Subsequent to
    obtaining the certificate of occupancy, the Property is expected to undergo
    a lease-up period. The Total Estimated Costs represent current estimates of
    total development costs, including amounts required to tenant the Property.
    These costs are estimates and are subject to change upon or prior to
    completion of the development.

(2) Equity Office and Wilson Investors ("WI") entered into a joint venture
    agreement to form Wilson/ Equity Office, LLC ("W/EO") for the purpose of
    developing, constructing, leasing and managing developments. W/EO is owned
    49.9% by Equity Office and 50.1% by WI. William Wilson III, a trustee of
    Equity Office, through his ownership of WI, owns approximately 22% of W/EO
    (and approximately 30% of any promote to which WI is entitled under the
    joint venture agreement). Equity Office will loan up to $25 million to WI
    for their required contribution to W/EO at a 15% return per annum. The
    current outstanding balance of this loan as of December 31, 2000, is
    approximately $4.1 million.

    Equity Office has created or anticipates creating joint ventures with W/EO,
    and, in certain cases, unaffiliated third parties, for the development
    properties included herein. The costs for these developments generally will
    be funded by Equity Office and W/EO in a 60%/40% ratio and in some cases by
    third parties as described within each development's respective operating
    agreement. The Board of Trustees has also authorized Equity Office to
    negotiate and enter into an agreement with W/EO providing for the extension
    of first mortgage financing to the ownership entities of each of these
    developments at LIBOR plus 2.4642%, generally maturing 36 months after
    initial funding, or earlier at the option of Equity Office in the event
    alternative financing sources are available on terms reasonably acceptable
    to WI and any unrelated third-party investors. The aggregate amount of any
    such financing would be generally capped at 70% of budgeted construction
    costs. In accordance with the W/EO

                                        42
<PAGE>   43

Operating Agreement, Equity Office is entitled to purchase the W/EO interest in
each development subsequent to project stabilization.

(3) The Estimated Placed in Service Date represents the date the certificate of
    occupancy has been or is currently anticipated to be obtained. Effective
    Ownership Percentage represents Equity Office's direct interest in the
    development and its 49.9% interest in W/EO. Costs Incurred as of December
    31, 2000, and Total Estimated Costs are based on Equity Office's Effective
    Ownership Percentage. The remaining ownership interest/costs are
    owned/funded by WI through its investment in W/EO and on certain
    developments unaffiliated third parties.

(4) Total Project Estimated Costs represents 100% of the estimated costs
    including Equity Office's, WI's and any unaffiliated third party's portions.
    These costs are subject to change upon or prior to the completion of the
    development and include amounts required to tenant the Property.

(5) Foundry Square is a project with four sites, each of which has a separate
    joint venture structure. Equity Office's Effective Ownership Percentages are
    approximately 68%, 64%, 40% and 40%.

(6) Under the terms of the lease for the property, the lessor is entitled to
    share, in addition to base rent, in 50% of proceeds from the operation and
    ownership of this development after a preferred 11% cumulative return to the
    lessee (8% prior to project stabilization). Other partners may share in
    excess cash flow, if any.

(7) Under the terms of the ground lease, the ground lessor is entitled to share,
    in addition to ground rent, in proceeds from the operation and ownership of
    this development after a 10% return to lessee, calculated at 25.7% of
    proceeds prior to a 14% cumulative return (18% after 2018) and 20.7%
    thereafter.

(8) Larkspur Landing is a potential development currently being evaluated by
    W/EO.

     In addition to the developments described above, Equity Office owns various
land parcels available for development. These sites represent possible future
development of up to approximately seven million square feet of office space.
The development of these sites will be impacted by the timing and likelihood of
success of the entitlement process, which is uncertain. These various sites
include, among others: Reston Town Center, Reston, VA; Prominence in Buckhead,
Atlanta, GA; Perimeter Center, Atlanta, GA; Tabor Center, Denver, CO; Orange
Center, Orange, CA; and City Center Bellevue, Bellevue, WA.

IMPACT OF NEW ACCOUNTING STANDARDS

     In June 1998, the FASB issued Statement No. 133 "Accounting for Derivative
Instruments and Hedging Activities." The statement requires recording all
derivative instruments as assets or liabilities, measured at fair value.
Derivatives that are not hedges must be adjusted to fair value through income.
If the derivative is a hedge, depending on the nature of the hedge, changes in
the fair value of derivatives will either be offset against the change in fair
value of the hedged assets, liabilities, or firm commitments through earnings or
recognized in other comprehensive income until the hedged item is recognized in
earnings. The ineffective portion of a derivative's change in fair value will be
immediately recognized in earnings. The standard's effective date was deferred
by FASB Statement No. 137 to all fiscal years beginning after June 15, 2000.
Equity Office adopted the standard on January 1, 2001 and recorded a cumulative
effect of a change in accounting principle resulting in a loss of approximately
$1.1 million. Management does not anticipate that the adoption will have a
material impact on Equity Office's financial condition and results of
operations.

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). Equity

                                        43
<PAGE>   44

Office believes that the majority of inflationary increases in expenses will be
offset, in part, by the expense reimbursements and contractual rent increases
described above.

FUNDS FROM OPERATIONS

     Management of Equity Office believes Funds from Operations, as defined by
the Board of Governors of the National Association of Real Estate Investment
Trusts ("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 GAAP, and it should not be considered as
an alternative to these indicators in evaluating liquidity or operating
performance of Equity Office.

     The following table reflects the calculation of Funds from Operations for
the years ended December 31, 2000, 1999 and 1998:

(1) The White Paper on Funds from Operations approved by 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 Funds from Operations to include all operating
    results, both recurring and non-recurring, except those defined as
    extraordinary under GAAP. In accordance with this NAREIT Bulletin, Equity
    Office no longer adjusts for the amortization of discounts and premiums on
    mortgages when calculating Funds from Operations. Accordingly, Equity Office
    restated the prior period data for comparative purposes. Equity Office
    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 Equity Office to
    incur and service debt, to make capital expenditures and to fund other cash
    needs. Equity Office computes Funds from Operations in

                                        44
<PAGE>   45

    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 Equity Office. 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 Equity Office's
    financial performance or to cash flow from operating activities, determined
    in accordance with GAAP, as a measure of Equity Office's liquidity, nor is
    it indicative of funds available to fund Equity Office's cash needs,
    including its ability to make cash distributions.

ITEM 8.  FINANCIAL STATEMENTS.

                         REPORT OF INDEPENDENT AUDITORS

The Board of Trustees and Shareholders of Equity Office Properties Trust

     We have audited the accompanying consolidated balance sheets of Equity
Office Properties Trust ("Equity Office") as of December 31, 2000 and 1999, and
the related consolidated statements of operations, shareholders' equity and
comprehensive income and cash flows for each of the three years in the period
ended December 31, 2000. Our audits also included the financial statement
schedule listed in the Index at Item 14(a). These financial statements and the
schedule are the responsibility of Equity Office's management. Our
responsibility is to express an opinion on these financial statements and the
schedule based on our audits.

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

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Equity Office
at December 31, 2000 and 1999, and the consolidated results of its operations
and its cash flows for each of the three years in the period ended December 31,
2000, in conformity with accounting principles generally accepted in the United
States. Also, in our opinion, the related financial statement schedule, when
considered in relation to the basic financial statements taken as a whole,
presents fairly in all material respects the information set forth therein.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 -- BUSINESS AND FORMATION OF EQUITY OFFICE

     As used herein, "Equity Office" means Equity Office Properties Trust, a
Maryland real estate investment trust, together with its subsidiaries, including
EOP Operating Limited Partnership, a Delaware limited partnership ("EOP
Partnership") and the predecessors thereof ("Equity Office Predecessors").
Equity Office 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 Equity Office, and to complete the consolidation of the Equity
Office Predecessors (the "Consolidation"). Equity Office completed its initial
public offering (the "IPO") on July 11, 1997 having sold its common shares of
beneficial interest, $0.01 par value per share ("Common Shares"). The net
proceeds from the IPO were contributed to EOP Partnership in exchange for units
of partnership interest ("Units"). Equity Office is a fully integrated,
self-administered and self-managed real estate company engaged in acquiring,
owning, managing, developing, leasing and renovating office properties and
parking facilities. Equity Office has elected to be taxed as a real estate
investment trust ("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
December 31, 2000, Equity Office owned or had an interest in 381 office
properties (the "Office Properties") containing approximately 99.0 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 for the Office Properties at December 31, 2000 was
approximately 94.6%. The Office Properties are located in 104 submarkets in 37
markets in 24 states and the District of Columbia. The Office Properties, by
rentable square feet, are located approximately 51.3% in central business
districts ("CBDs") and 48.7% in suburban markets.

NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

     Equity Office's assets, which include investments in joint ventures, are
primarily owned by, and its operations are substantially conducted through, EOP
Partnership. Equity Office is the sole general partner of EOP Partnership. Due
to Equity Office's ability as general partner to control EOP Partnership and
various other property holding entities and various other subsidiaries, each
such entity has been consolidated with Equity Office for financial reporting
purposes. All intercompany transactions and balances have been eliminated in
consolidation.

     The Consolidation, the Beacon Merger and the Cornerstone Merger were
accounted for as purchases in accordance with Accounting Principles Board
Opinion No. 16. Accordingly, the fair value of the consideration given by Equity
Office was used as the valuation basis for these transactions. The assets
acquired and liabilities assumed by Equity Office were recorded at their fair
values as of the closing dates of the Consolidation, the Beacon Merger and the
Cornerstone Merger, as applicable, and the excess of the purchase price over the
related historical basis of the net assets acquired was allocated primarily to
investment in real estate.

Investment in Real Estate

     Rental property and improvements, including interest and other costs
capitalized during construction, are included in investment in real estate and
are stated at cost. Expenditures for ordinary maintenance and repairs are
expensed to operations as they are incurred. Significant renovations and
improvements, which improve or extend the useful life of the assets are
capitalized. Except for amounts attributed to land, rental property and

                                        53

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED)

improvements are depreciated over their estimated useful lives using the
straight-line method. The estimated useful lives by asset category are:

<S>                                                            <C>

Tenant improvements.........................................       Term of lease
Furniture and fixtures......................................          3-12 years
</TABLE>

Deferred Leasing and Financing Costs

     Deferred leasing and financing costs are recorded at cost. The deferred
leasing costs are amortized over the terms of the respective leases and the
deferred financing costs are amortized over the terms of the respective
financings on a straight-line basis, which approximates the effective yield
method.

Rental Income

     Certain leases provide for tenant occupancy during periods for which no
rent is due or where minimum rent payments increase during the term of the
lease. Equity Office records rental income for the full term of each lease on a
straight-line basis. Accordingly, a receivable is recorded from tenants for the
amount that is expected to be collected over the remaining lease term rather
than currently ("Deferred Rent Receivable"). When a property is acquired the
term of existing leases is considered to commence as of the acquisition date for
purposes of this calculation. The amounts included in rental income for the
years ended December 31, 2000, 1999 and 1998, which were not currently
collectible as of such dates, were approximately $69.8 million, $65.4 million
and $68.1 million, respectively. Deferred Rent Receivable is not recognized for
income tax purposes.

Cash Equivalents

     Cash equivalents are considered to be all highly liquid investments
purchased with a maturity of three months or less at the date of purchase.

Escrow Deposits and Restricted Cash

     Escrow deposits primarily consist of amounts held by lenders to provide for
future real estate tax expenditures and tenant improvements, earnest money
deposits on acquisitions and net proceeds from tax-exempt dispositions.
Restricted cash represents amounts committed for various utility deposits and
security deposits. Certain of these amounts may be reduced upon the fulfillment
of certain obligations.

Fair Value of Financial Instruments

     Investments in marketable equity securities and investments in notes
receivable are reported at fair value and included in other assets. All
marketable equity securities held at December 31, 2000 were designated as
available for sale, with unrealized holding gains and losses included in
shareholders' equity as accumulated other comprehensive (loss) income.

     Management believes that the carrying basis of the long-term debt
consisting of secured and unsecured borrowings and interest rate protection
agreements approximate their respective fair market values as of December 31,
2000 and 1999, respectively. The current value of debt was computed by
discounting the projected debt service payments for each loan based on the
spread between the market rate and the effective rate, including the
amortization of loan origination costs, for each year. In addition, the carrying
values of cash

                                        54
<PAGE>   55

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED)

equivalents, restricted cash, escrow deposits, tenant and other rents
receivable, accounts payable and accrued expenses are reasonable estimates of
their fair value.

Interest Rate Protection Agreements

     Equity Office periodically enters into certain interest rate protection
agreements to effectively convert or cap floating rate debt to a fixed rate
basis, as well as to hedge anticipated future financing transactions. Net
amounts paid or received under these agreements are recognized as an adjustment
to interest expense when such amounts are incurred or earned. Settlement amounts
paid or received in connection with terminated interest rate protection
agreements are deferred and amortized as an adjustment to interest expense over
the term of the related financing transaction on a straight-line basis, which
approximates the effective yield method.

Derivatives and Hedging Activities

     In June 1998, the FASB issued Statement No. 133 "Accounting for Derivative
Instruments and Hedging Activities." The statement requires recording all
derivative instruments as assets or liabilities, measured at fair value.
Derivatives that are not hedges must be adjusted to fair value through income.
If the derivative is a hedge, depending on the nature of the hedge, changes in
the fair value of derivatives will either be offset against the change in fair
value of the hedged assets, liabilities, or firm commitments through earnings or
recognized in other comprehensive income until the hedged item is recognized in
earnings. The ineffective portion of a derivative's change in fair value will be
immediately recognized in earnings. The standard's effective date was deferred
by FASB Statement No. 137 to all fiscal years beginning after June 15, 2000.
Equity Office adopted the standard on January 1, 2001 and recorded a cumulative
effect of a change in accounting principle resulting in a loss of approximately
$1.1 million. Management does not anticipate that the adoption will have a
material impact on Equity Office's financial condition and results of
operations.

Deferred Revenue

     During 2000 and 1999, Equity Office received common stock and/or warrants
to purchase common stock for allowing companies that provide telecommunication
and other services access to the Properties. The securities received from these
companies were recorded as deferred revenue at fair value at the time such
securities were earned and are included in other liabilities on the balance
sheet. The deferred revenue will be amortized into other income over the terms
of the respective license agreements. As of December 31, 2000 and 1999,
approximately $37.2 million and $31.6 million is recorded as deferred revenue
relating to these agreements and is being amortized over a five-year period.
Approximately $5.7 million and $.7 million was recorded as other income during
2000 and 1999, respectively.

Income Taxes

     The Office Properties and Parking Facilities primarily are owned by limited
partnerships or limited liability companies, which are substantially
pass-through entities. Some of the pass-through entities have corporate general
partners or members, which are subject to federal and state income and franchise
taxes. In addition, the management business is owned by a corporation and is
subject to federal and state income taxes. Equity Office incurred federal and
state income and franchise taxes of approximately $2.7 million, $0.7 million and
$1.7 million for the years ended December 31, 2000, 1999 and 1998, respectively,
which are included in general and administrative expenses.

     Equity Office has elected to be taxed as a REIT, under Sections 856 through
860 of the Internal Revenue Code of 1986, as amended (the "Code"). As a REIT,
Equity Office generally will not be subject to federal income tax if it
distributes 100% of its taxable income for each tax year to its shareholders.
REITs are subject

                                        55
<PAGE>   56

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED)

to a number of organizational and operational requirements. If Equity Office
fails to qualify as a REIT in any taxable year, it will be subject to federal
income tax (including any applicable alternative minimum tax) on its taxable
income at regular corporate tax rates. Even if Equity Office qualifies for
taxation as a REIT, Equity Office may be subject to state and local income taxes
and to federal income tax and excise tax on its undistributed income. The
aggregate cost of land and depreciable property for federal income tax purposes
as of December 31, 2000 and 1999 was approximately $12.2 billion and $10.3
billion, respectively.

     Reconciliation of Net Income to Estimated Taxable Income (Unaudited)

     Earnings and profits, which determine the taxability of distributions to
stockholders, differ from net income reported for financial reporting purposes
due to differences for U.S. Federal tax purposes in the estimated useful lives
and methods used to compute depreciation and the carrying value (basis) of the
investments in properties, among other things. The following table reconciles
Equity Office's net income to estimated taxable income for the year ended
December 31, 2000:

</TABLE>

Minority Interests

     EOP Partnership

     Net income is allocated to minority interests based on their respective
ownership percentage of EOP Partnership. The ownership percentage is calculated
by dividing the number of Units held by the minority interests by the total
Units held by both the minority interests and Equity Office. Issuance of
additional Common Shares and Units changes the ownership interests of both the
minority interests and Equity Office. Such transactions and the proceeds
therefrom are treated as capital transactions.

     Partially Owned Properties

     Minority interests in partially owned properties is reflected on the
balance sheet for the portion of properties consolidated that are not wholly
owned. The earnings or losses from these properties attributable to the minority
interests are reflected as minority interests in partially owned properties in
the statements of operations.

Use of Estimates

     The preparation of the consolidated financial statements 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.

Reclassifications

     Certain reclassifications have been made to the previously reported 1999
and 1998 statements in order to provide comparability with the 2000 statements
reported herein. These reclassifications have not changed the 1999 or 1998
results or shareholders' equity.

NOTE 3 -- CORNERSTONE MERGER

     On June 19, 2000, Equity Office, EOP Partnership, Cornerstone Properties
Inc. ("Cornerstone") and Cornerstone Properties Limited Partnership
("Cornerstone Partnership") completed the merger of Cornerstone Partnership with
and into EOP Partnership and the merger of Cornerstone with and into Equity
Office (collectively, the "Cornerstone Merger") at a total cost of approximately
$4.5 billion. The purchase price consisted of:

        (1) the issuance by Equity Office of approximately 51.2 million Common
        Shares valued at $24.68 per share and the issuance of approximately 3.7
        million share options for a total of approximately $1,268.6 million;
        (2) the issuance by EOP Partnership of approximately 12.4 million Units
        to third parties valued at $24.68 per Unit for a total of approximately
        $306.0 million;
        (3) the cash redemption of approximately 58.5 million shares of
        Cornerstone common stock valued at $18.00 per share for a total of
        approximately $1,052.2 million;
        (4) the cash redemption of approximately 3.0 million shares of
        Cornerstone preferred stock valued at $18.00 per share, plus accrued but
        unpaid dividends, for a total of approximately $57.6 million;
        (5) the assumption of approximately $1,304.9 million of secured debt and
        $415.5 million of unsecured debt;
        (6) the payment of merger costs of approximately $82.9 million; and
        (7) the assumption of net liabilities of approximately $19.8 million.

Certain of the amounts stated above related to the Cornerstone Merger are based
on management's current best estimates, which are subject to adjustment within
one year of the closing date of June 19, 2000.

     The cash portion of the Cornerstone Merger of approximately $1.2 billion
was funded from various credit facilities (see Note 10 -- Lines of Credit and
Term Loans for more information). As a result of the Cornerstone Merger, Equity
Office acquired an interest in 82 Office Properties containing approximately
18.9 million square feet of office space.

     In 1999, Equity Office acquired a 67% share of a $202.2 million
mezzanine-level debt position for approximately $73.9 million as part of a debt
restructuring related to the SunAmerica Center office property. The discount to
the face amount of the note of approximately $64.2 million will be amortized to
interest income based on the estimated yield of the investment. The note accrues
interest at 7.25% per annum and matures on August 31, 2014. In addition, Equity

(1) The amounts shown above approximate Equity Office's economic ownership
    interest for the periods presented. Cash flow from operations, capital
    transactions and net income are allocated to the joint venture partners in
    accordance with their respective partnership agreements. Equity Office's
    share of these items is subject to change based on, among other things, the
    operations of the Property and the timing and amount of capital
    transactions. Equity Office's legal ownership may differ.

(2) On August 2, 2000, a joint venture between Equity Office and an unaffiliated
    party acquired a 45% general partner equity interest and a debt interest in
    a limited partnership that owns 1301 Avenue of the Americas, a 1.77 million
    square foot office building located in Midtown Manhattan in New York. Equity
    Office's share of the investment at closing was approximately $163.2
    million. In addition, Equity Office 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 described in the option agreements.

(3) The interest in One Post was acquired as part of the Cornerstone Merger.

(4) On June 2, 2000, Equity Office 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. See Note 5 -- Dispositions.

(5) See Note 21 -- Related Party Transactions, subfootnote (6). Foundry Square
    is a project with four sites, each of which has a separate joint venture
    structure. Equity Office's economic ownership interests are approximately
    68%, 64%, 40% and 40%.

     These investments are accounted for using the equity method of accounting
except for the investment in Four Oaks Place, which is accounted for utilizing
the cost method of accounting. Under the equity method of accounting, the net
equity investment of Equity Office is reflected on the consolidated balance
sheets, and the consolidated statements of operations include Equity Office's
share of net income or loss from the unconsolidated joint ventures. Any
difference between the carrying amount of these investments on the balance
sheets of Equity Office and the underlying equity in net assets is depreciated
as an adjustment to income from unconsolidated joint ventures over 40 years.

     Combined summarized financial information of the unconsolidated joint
ventures is as follows:

NOTE 10 -- LINES OF CREDIT AND TERM LOANS

     On August 14, 1998, Equity Office completed a term loan agreement with
various financial institutions to provide Equity Office with a $328 million
unsecured term loan facility (the "$328 Million Credit Facility"). The $328
Million Credit Facility was priced at 90-day LIBOR plus 80 basis points and was
prepayable on any interest payment date. The term loan had a maturity date of
August 15, 2000. On August 9, 1999, Equity Office prepaid the $328 Million
Credit Facility with proceeds from a line of credit and approximately $.2
million of unamortized loan costs were written-off and accounted for as an
extraordinary loss.

     During 1999, Equity Office had a $1.0 billion credit facility (the "$1.0
Billion Credit Facility"). Equity Office incurred fees of approximately $2.5
million at the closing for the facility, which, along with approximately $1.0
million of unamortized deferred financing costs from a previous line of credit,
were amortized over the term of the $1.0 Billion Credit Facility. The interest
rate was based on Equity Office's investment grade rating on its unsecured debt
and was at LIBOR plus 60 basis points with a facility fee, based on the
aggregate amount of the facility, equal to 20 basis points per annum.

     When the Cornerstone Merger was completed, the cash portion of the merger
consideration of approximately $1.2 billion was funded from the $1.0 Billion
Credit Facility and a new $1.0 billion credit facility (the "Line of Credit"),
which was obtained in May 2000. Concurrently with the Cornerstone Merger, Equity
Office borrowed $1.0 billion from the $1.0 Billion Credit Facility and amended
the facility into a term loan (the "Term Loan"). Interest on the Term Loan was
based on LIBOR plus 80 basis points and was scheduled to mature on May 29, 2001.
The Term Loan was repaid in full using proceeds from several debt offerings
completed during the latter part of 2000. As a result, Equity Office incurred an
extraordinary loss of $.9 million representing unamortized deferred loan costs.

     The remaining cash consideration in the Cornerstone Merger was funded from
the Line of Credit, which bears interest at LIBOR plus 60 basis points and
matures on June 19, 2003. There is also an annual facility fee of $2.0 million
payable quarterly. In addition, a competitive bid option, whereby the lenders
participating in the credit facility bid on the interest rate to be charged is
available for up to $350 million of the borrowings under the Line of Credit. In
addition, as part of the Cornerstone Merger, Equity Office assumed interest rate
protection agreements in the notional amount of $250 million ($185 million
terminated in December 2000 and the remaining interest rate protection
agreements terminated in January 2001). These interest rate protection
agreements effectively converted a portion of the Line of Credit to a
fixed-blended interest rate of 4.6% during the term of the protection
agreements.

     In January 2000, Equity Office obtained an additional unsecured borrowing
facility from Chase Manhattan bank for short-term borrowings not to exceed $300
million in the aggregate. Upon request of Equity Office, and at the lender's
option, the lender could offer to lend funds at mutually agreed upon interest
rates and terms, as determined by current market conditions. In April 2000,
borrowings under this facility in the amount of $100 million were repaid with
proceeds from the $1.0 Billion Credit Facility and the agreement was terminated.

NOTE 21 -- RELATED PARTY TRANSACTIONS -- (CONTINUED)

Office was a principal of this law firm until September 1, 1997. In 1999,
Rosenberg & Liebentritt, P.C. dissolved and, as a result, no longer provides
     legal services to Equity Office.

(2) Represents amounts paid to EGI Risk Services Inc. for reimbursement of
    property insurance premiums to an affiliated company and fees for risk
    management services including reviewing, obtaining and/or researching
    various insurance policies. EGI Risk Services, Inc. was a wholly owned
    subsidiary of the Equity Group, of which Mr. Samuel Zell is the Chairman of
    the Board. Effective October 1, 1999, Equity Office no longer utilizes the
    services provided by EGI Risk Services Inc., and its employees have become
    employees of Equity Office.

(3) H. Jon Runstad, a former trustee who resigned in July 2000, is a principal
    of Wright Runstad & Company, the general partner of Wright Runstad
    Associates Limited Partnership ("WRALP") which provides property management,
    leasing and development services. Equity Office and an affiliate together
    own a 30% limited partnership interest in WRALP. During 2000, 1999 and 1998,
    Equity Office received distributions of approximately $9.7 million, $2.7
    million and $1.4 million, respectively from WRALP. Since December 1997,
    WRALP served as the co-property manager with Equity Office and leasing agent
    for certain Office Properties acquired in December 1997 from WRALP and for
    several other Office Properties. In addition to the amounts paid above to
    WRALP for development and management fees, leasing commissions and related
    expense reimbursements with respect to some of our Properties, an additional
    $5.0 million, $4.7 million and $3.8 million was paid during 2000, 1999 and
    1998, respectively, to WRALP for the reimbursement of salaries of personnel
    in connection with such management services.

     WRALP owned a 20% interest and Equity Office owned an 80% interest in
     Sunset North Corporate Campus, a three-building office complex located in
     Bellevue, Washington. WRALP served as the developer of the project. On June
     30, 2000, Equity Office acquired the interest held by WRALP at a price
     based on a formula set forth in the joint venture agreement. See Note 4 for
     additional information.

     WRALP owns a 20% interest and Equity Office owns an 80% interest in Key
     Center, an Office Property located in Bellevue, Washington. WRALP served as
     the developer of the project and currently serves as the co-property
     manager with Equity Office and the leasing agent.

     On September 8, 2000, Equity Office obtained the World Trade Center East
     located in Seattle, Washington, from WRALP. WRALP served as the developer
     of the project. See Note 4 for additional information.

     In accordance with the agreement governing the investment in WRALP, Equity
     Office agreed to make available to WRALP up to $20.0 million in additional
     financing or credit support for future development. As of December 31,
     2000, no amounts have been funded pursuant to this agreement. However,
     Equity Office has guaranteed WRALP's line of credit, which has an
     outstanding balance of approximately $18.1 million as of December 31, 2000.

     Wright Runstad & Company leases space in certain Office Properties. The
     terms of the leases are consistent with terms of unaffiliated tenant's
     leases. Total rents and other amounts paid by Wright Runstad & Company
     under its lease were approximately $.5 million, $.3 million and $.3 million
     for the years ended December 31, 2000, 1999 and 1998, respectively.

     As mentioned above, Mr. Runstad resigned as a trustee of Equity Office in
     July 2000. Transactions with WRALP will no longer be considered related
     party transactions.

(4) Equity Office leases its corporate office space from an affiliate of the
    Equity Group.

(5) During 1999, fees were paid to the Equity Group for miscellaneous consulting
    services. In 1998 administrative services also included fees paid to Equity
    Group for centralized services, such as real estate tax consulting, payroll
    processing, employee benefits and telecommunications, all of which are now
    performed by Equity Office.

(6) Equity Office and Wilson Investors ("WI") entered into a joint venture
    agreement to form Wilson/ Equity Office, LLC ("W/EO") for the purpose of
    developing, constructing, leasing and managing developments. W/EO is owned
    49.9% by Equity Office and 50.1% by WI. William Wilson III, a trustee of
    Equity Office, through his ownership of WI, owns approximately 22% of W/EO
    (and approximately 30% of any promote to which WI is entitled under the
    joint venture agreement). Equity Office will loan up to $25 million to WI
    for their required contribution to W/EO at a 15% return per annum. The
    current outstanding balance of this loan as of December 31, 2000, is
    approximately $4.1 million. Equity Office's investment in W/EO as of
    December 31, 2000 is approximately $15.5 million, which is net of a net loss
    allocation of approximately $.7 million.

     As of December 31, 2000, Equity Office has created or anticipates creating
     joint ventures with W/EO, certain of which have unaffiliated parties, for
     the purpose of developing office properties. The total square footage that
     may be developed is approximately 2.3 million and the total projected
     estimated cost, including Equity Office's, WI's and any unaffiliated
     party's share, to complete the developments is approximately $770.2
     million. Equity Office's share of the cost incurred to date for the
     properties under development with W/EO is approximately $480.3 million.
     William Wilson III did not, in his capacity as trustee, approve the
     foregoing arrangements with Equity Office.

(7) In connection with the Cornerstone Merger, $250 million of mortgage debt was
    assumed on certain properties payable to Stichting Pensioenfonds voor de
    Gezondheid, Gaestelijke en Meatshappelljke Belangen ("PGGM"), of which Jan
    H.W.R. van der Vlist, a trustee of Equity Office, is a director of real
    estate. In October 2000, Equity Office repaid $65 million encumbering one of
    the Properties, TransPotomac Plaza, upon its maturity. At December 31, 2000,
    $185 million of principal and approximately $3.5 million of accrued interest
    was payable to PGGM.

     In connection with the Cornerstone Merger, Equity Office paid $5.0 million
to John S. Moody to enter into a non-compete agreement. Mr. Moody became a
trustee of Equity Office at the time of the Cornerstone Merger and is the former
president and chief executive officer of Cornerstone.

     Equity Office acquired Palo Alto Square, an Office Property located in Palo
Alto, California, on October 1, 1999, from a private investment partnership
controlled by Mr. Samuel Zell. The acquisition was funded primarily through the
issuance of 1,035,389 Units valued at $23.64 per Unit for a total of
approximately $24.5 million and the assumption of $53.2 million in debt.

     Equity Office has an investment in Allied Riser Corporation ("ARC") (See
Note 7 -- Investment in Securities for additional information). A private
investment entity controlled by Mr. Zell also has a substantial investment in
ARC.

     As disclosed in Note 7 -- Investment in Securities, Equity Office owns
preferred shares of Capital Trust. Mr. Zell is Chairman of the Board of Capital
Trust.

Amounts Received from Related Parties

     Related parties of Equity Office, including WRALP, leased space in certain
Office Properties. Total rents and other amounts paid by these related parties
under the terms of their respective leases were approximately

$1.2 million, $1.2 million and $0.3 million for the years ended December 31,
2000, 1999 and 1998, respectively. In addition, in 2000 and 1999 Equity Office
provided real estate tax consulting and risk management services to related
parties for which it received approximately $1.4 million and $1.2 million,
respectively.

NOTE 22 -- SHARE OPTION PLAN AND SHARE AWARD PLAN

     Equity Office has established the 1997 Share Option and Share Award Plan,
as amended (the "Employee Plan"). The purpose of the Employee Plan is to attract
and retain highly qualified executive officers, trustees, employees and
consultants. Through the Employee Plan, certain officers, trustees, employees
and consultants of Equity Office are offered the opportunity to acquire Common
Shares pursuant to grants of (i) options to purchase Common Shares ("Options")
and (ii) Share Awards (defined below). The Employee Plan is administered by the
Compensation and Option Committee (the "Compensation Committee"), which is
appointed by the Board of Trustees. The Compensation Committee determines those
officers, trustees, key employees and consultants to whom, and the time or times
of which, grants of Options and Share Awards will be made. The Compensation
Committee interprets the Employee Plan, adopts rules relating thereto and
determines the terms and provisions of Options. In 2000, 1999 and 1998 the
Common Shares subject to Options and Share Awards under the Employee Plan were
limited to 20,873,729, 19,433,472 and 11,121,786, respectively. The maximum
aggregate number of Common Shares that may be granted for all rights under the
Plan may not exceed 6.8% of the outstanding shares, calculated on a fully
diluted basis and determined annually on the first day of each calendar year. No
more than one-half of the maximum aggregate number of Common Shares shall be
granted as Share Awards. To the extent that Options expire unexercised or are
terminated, surrendered or canceled, the Common Shares allocated to such Options
shall become available for future grants under the Plan, unless the Plan has
terminated. The Employee Plan will terminate at such times as it issues all of
the unissued Common Shares reserved for the Plan. The Board of Trustees may at
any time amend or terminate the Employee Plan, but termination will not affect
Options and Share Awards previously granted. Any Options or Share Awards, which
vest prior to any such termination, will continue to be exercisable by the
holder thereof.

     The Compensation Committee determines the vesting schedule of each Option
and the term, which shall not exceed ten years from the date of the grant. As to
the Options that have been granted through December 31, 2000, the vesting
schedules range from the entire option grant being exercisable as of the grant
date, to one-third of the Options being exercisable as of the first anniversary
of the grant date, an additional one-third being exercisable as of the second
anniversary of the grant date and the remaining one-third of the Options being
exercisable as of the third anniversary of the grant date. The exercise price
for all Options under the Employee Plan shall not be less than the fair market
value of the underlying Common Shares at the time the Option is granted.

     Each member of the board of trustees receives an annual grant of an Option
to purchase 10,000 common shares on the date of each annual meeting of
shareholders. If an individual becomes a member of the board other than at an
annual meeting, he or she is entitled to a prorated Option grant based upon the
number of days until the next annual meeting of shareholders. In addition, the
Employee Plan permits the issuance of Share Awards to executive officers,
trustees and key employees upon such terms and conditions as are determined by
the Compensation Committee in its sole discretion. A share award is an award of
Common Shares, which (i) may be fully vested upon issuance ("Share Awards") or
(ii) may be subject to risk of forfeiture under Section 83 of the Internal
Revenue Code ("Restricted Share Award"). Generally, members of the Board of
Trustees have been granted Share Awards pursuant to the Employee Plan as payment
of their board fees. In addition, certain senior officers were issued Share
Awards as part of their bonus for fiscal year 2000 and 1999. In each case, the
number of Share Awards granted to trustees and senior officers was equal to the
dollar value of the fees or bonus earned divided by the fair market value of the
shares on the date the fee or bonus would have been paid. In addition to these
Share Awards, Restricted Share Awards were granted to

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

NOTE 22 -- SHARE OPTION PLAN AND SHARE AWARD PLAN -- (CONTINUED)

certain officers and employees in 2000, 1999 and 1998. The Restricted Share
Awards vest over a five year period as follows: (a) 50% on the third anniversary
of the initial grant date; (b) 25% on the fourth anniversary of the initial
grant date; and (c) the remaining 25% on the fifth anniversary of the initial
grant date.

     Equity Office has elected to apply the provisions of Accounting Principles
Board Opinion No. 25, "Accounting for Stock Issued to Employees" ("APB No. 25")
in the computation of compensation expense. Under APB No. 25's intrinsic value
method, compensation expense is determined by computing the excess of the market
price of the shares over the exercise price on the measurement date. For
Options, there is no intrinsic value on the measurement date (or grant date),
and no compensation expense is recognized. Financial Accounting Standards Board
No. 123 ("FASB No. 123") requires the disclosure of pro forma net income and net
income per share as if a fair value based accounting method had been used in the
computation of compensation expense. The fair value of the Options computer
under FASB No. 123 would be recognized over the vesting period of the Options.
The fair value for Options granted in 2000, 1999, and 1998 was estimated at the
time the Options were granted using the Black-Scholes option-pricing model with
the following weighted average assumptions for 2000, 1999, and 1998,
respectively:

</TABLE>

     The Black-Scholes option valuation model was developed for use in
estimating the fair value of trade options, which have no vesting restrictions
and are fully transferable. In addition, option valuation models require the
input of highly subjective assumptions, including the expected stock price
volatility. Because the Options have characteristics significantly different
from those traded options, and because changes in the subjective input
assumptions can materially affect the fair value estimate, in management's
opinion, the existing models do not necessarily provide a reliable single
measure of the fair value of its Options and may not be representative of the
effects on reported net income for future years. For purposes of pro forma
disclosures, the estimated fair value of the Options is amortized to expense
during the Options' vesting period. The following is the unaudited pro forma
information for the years ended December 31, 2000, 1999 and 1998.

Exercise prices for the 13,221,371 Options outstanding as of December 31, 2000
ranged from $12.09 to $33.00, with a weighted average exercise price of $24.82.
Expiration dates ranged from July 11, 2007 to August 2010. The remaining
weighted average contractual life of Options was 7.8 years. The weighted average

NOTE 23 -- 401(K) PLAN

     The Equity Office Properties Trust Section 401(k) Savings/Retirement Plan
(the "401(k) Plan") was established to cover eligible employees of Equity Office
and employees of any designated affiliate. The 401(k) Plan permits eligible
persons to defer up to 16% of their annual compensation, subject to certain
limitations imposed by the Internal Revenue Code. The employees' elective
deferrals are immediately vested and nonforfeitable upon contribution to the
401(k) Plan. Equity Office matches dollar for dollar employee contributions to
the 401(k) Plan up to 4% of the employees' annual salary. In addition, Equity
Office may elect to make a discretionary profit sharing contribution. Equity
Office incurred expense of approximately $3.6 million, $2.9 million and $2.4
million in each of the three years ended December 31, 2000, 1999 and 1998,
respectively, related to the 401(k) Plan.

NOTE 24 -- COMMITMENTS AND CONTINGENCIES

Concentration of Credit Risk

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

Environmental

     Equity Office, as an owner of real estate, is subject to various
environmental laws of federal and local governments. Compliance by Equity Office
with existing laws has not had a material adverse effect on Equity Office's
financial condition and results of operations, and management does not believe
it will have such an impact in the future. However, Equity Office 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

     Neither Equity Office nor any of its Properties is presently subject to
material litigation nor, to Equity Office's knowledge, is any litigation
threatened against Equity Office or any of the Properties, other than 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, results of operations, or business or
financial condition of Equity Office.

Insurance

     Equity Office is self-insured for certain amounts related to losses that
may be incurred at the Properties and has third party insurance coverage for
specified amounts above the deductible amounts. However, management does not
believe that this exposure will have a material adverse effect on Equity Office.

     Equity Office carries earthquake insurance on all of the Properties,
including those located in California, subject to coverage limitations which
Equity Office believes are commercially reasonable. In light of the California
earthquake risk, California building codes since the early 1970s have
established construction standards for all new buildings. The current and
strictest construction standards were adopted in 1987. Of the 104 Properties
located in California, 19 have been built since January 1, 1988, and Equity
Office believes that all of the Properties were constructed in full compliance
with the applicable standards existing at the time of construction. No assurance
can be given that material losses in excess of insurance proceeds will not occur
in the future.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

NOTE 24 -- COMMITMENTS AND CONTINGENCIES -- (CONTINUED)

Commitments

     In accordance with the agreement governing the investment in WRALP, Equity
Office agreed to make available to WRALP up to $20.0 million in additional
financing or credit support for future development. As of December 31, 2000, no
amounts have been funded pursuant to this agreement. However, Equity Office has
guaranteed WRALP's line of credit, which has an outstanding balance of
approximately $18.1 million as of December 31, 2000.

Contingencies

     Certain Properties owned in joint ventures with unaffiliated parties have
buy/sell options that may be exercised to acquire the other venturer's interest
by either Equity Office or its joint venture partner if certain conditions are
met as defined in the respective joint venture agreement.

     In connection with the acquisition of certain Properties, Equity Office has
agreed not to sell such Properties in a taxable transaction for a period of time
as defined in their respective agreements, or Equity Office may be obligated to
make additional payments to the respective sellers.

     The holders of the Wright Runstad & Company options (the "WR Holders")
exercised their option to extend the date to August 13, 2001 at which time the
WR Holders can require Equity Office 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
Equity Office is obligated to pay to the WR Holders for each Common Share sold
at such lower price an amount equal to the difference between $29.10625 and such
lower price, not to exceed $3.00 per Common Share. Any amounts paid by Equity
Office as a result of such sales will be recorded as a reduction in
shareholders' equity. For put options exercised on August 13, 2001, 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 put option settlement. The
$4.1 million portion of the total potential payment has been reflected as a put
option settlement on a straight-line basis over the period between August 13,
1999 and August 13, 2000.

     In connection with the acquisition of Worldwide Plaza on October 1, 1998,
Equity Office issued a transferable put option on the 6,861,166 Units issued in
the transaction, 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 25 -- SUBSEQUENT EVENTS

     1. On January 19, 2001, the mortgage note encumbering Palo Alto Square was
prepaid. The total payoff was approximately $50.2 million which included accrued
interest of approximately $.2 million.

     2. On January 25, 2001, Warner Park Center in Woodland Hills, CA was
disposed of for approximately $8.95 million to Adler Realty Advisors, Inc. and
its investors. The building consisted of 57,366 square feet and was 66.3%
occupied.

     3. In February 2001, Equity Office and Booz Allen & Hamilton, a management
and technology-consulting firm, entered into a 12-year lease for 122,000 square
feet of office space in an office building to be developed by Equity Office. The
office building, named EJ Randolph II, will be located in McLean, Virginia, and
is expected to be completed in 2002 at a cost of approximately $35.7 million.

NOTE 25 -- SUBSEQUENT EVENTS -- (CONTINUED)

     4. On February 15, 2001, the mortgage note encumbering Community Corporate
Center was prepaid. The total payoff amount was approximately $16.5 million.

     5. On February 22, 2001, Equity Office and Spieker Properties, Inc.
("Spieker") entered into a merger agreement in which Spieker will merge into
Equity Office and EOP Partnership will acquire Spieker Properties, L.P.,
Spieker's operating partnership subsidiary (the "Spieker Merger"). The
transaction values Spieker (including the outside interests in Spieker
Properties, L.P.) at approximately $7.2 billion, which includes transaction
costs and the assumption of approximately $2.1 billion in debt and $431 million
in preferred stock and partnership units. Equity Office will pay approximately
$1.085 billion in cash and issue approximately 118.6 million new Equity Office
common shares and EOP Partnership Units and 14.3 million new Equity Office
preferred shares in the transaction. We intend to finance the $1.085 billion
cash portion of the purchase price using a combination of available borrowing
capacity under our existing Line of Credit, and a new bridge loan facility to be
entered into before the closing of the merger and/or through the issuance by EOP
Partnership of senior unsecured notes.

     Following the merger, Equity Office will own and operate 616 office
buildings consisting of 124 million square feet of office space nationwide,
which includes 25 million square feet of office space attributable to Spieker.
Equity Office will also acquire Spieker's industrial portfolio of approximately
13.5 million square feet and its development properties totaling 1.7 million
square feet.

     Upon completion of the merger, Equity Office will expand its Board of
Trustees from 13 to 16 members. The new members will be Warren Spieker, chairman
of Spieker, and Co-Chief Executive Officers Craig Vought and John Foster.

     The merger is intended to qualify as a tax-free reorganization at the
corporate level for federal income tax purposes, with Spieker stockholders
recognizing taxable income only up to the amount of cash received in the merger.
The closing of the transaction is conditioned upon each party receiving an
acceptable tax opinion to that effect. The merger, which will be accounted for
using purchase accounting, is subject to the approval of the shareholders of
both companies and to other customary conditions.

     6. On February 23, 2001, the mortgage note encumbering Wachovia was
prepaid. The total payoff was approximately $25.3 million.
