ITEM 1.  BUSINESS.

                                EOP PARTNERSHIP

     As used herein, the terms "we," "us," "our," or "EOP Partnership" refer to
EOP Operating Limited Partnership, a Delaware limited partnership. EOP
Partnership is a subsidiary of Equity Office Properties Trust ("Equity Office")
which 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 our predecessors.
Equity Office completed its 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. Equity
Office's assets, which include investments in joint ventures, are owned by, and
substantially all of its operations are conducted through, EOP Partnership.
Equity Office is the general partner of EOP Partnership. Equity Office 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 it
distributes 100% of its taxable income and complies 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.

     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 Equity Office's 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 our merger
with Cornerstone Properties Limited Partnership, 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, EOP Partnership acquired an interest in 82 Office Properties
containing approximately 18.9 million square feet of office space.

                             PENDING 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. EOP Partnership will pay approximately $1.085 billion in cash
and issue approximately 118.6 million new EOP Partnership units and 14.3 million
new EOP Partnership preferred units 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, a new bridge
loan facility to be entered into before the closing of the merger and/or through
the issuance of senior unsecured notes.

     Following the Spieker Merger, EOP Partnership is expected to 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. EOP Partnership will also own 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 Spieker 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 Spieker Merger, which will be accounted for using purchase accounting,
is subject to the approval of the shareholders of Equity Office and Spieker and
the partners of EOP Partnership and Spieker Partnership, as applicable, 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 unitholder 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;

          (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;
                                        4
<PAGE>   5

          (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

     The seven executive officers of Equity Office have an average tenure of
11.5 years with Equity Office or its affiliates and an average of 22 years
experience in the real estate industry.

                                  COMPETITION

     The leasing of real estate is highly competitive. EOP Partnership'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. EOP Partnership 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, EOP Partnership 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

     EOP Partnership's primary business is the ownership and operation of Office
Properties. EOP Partnership's long-term tenants are in a variety of businesses
and no single tenant is significant to EOP Partnership'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.

issued 73,776 Units valued at $28.75 per Unit (the Units were recorded at a
value of $32.11 per Unit for a total of $2.4 million for accounting purposes)
for the remaining 11% interest in certain partnerships that collectively own 11
office buildings located in suburban Philadelphia, Pennsylvania. We acquired an
89% interest in the partnerships in 1997. In addition, in December 2000 EOP
Partnership issued 42,397 Units valued at $29.825 per Unit in connection with
the acquisition of rights to certain land located in San Francisco, California.
The Units issued in these transactions were issued as a private placement of
securities in reliance on an exemption from the registration requirements of the
Securities Act pursuant to Section 4(2) and Rule 506 of Regulation D promulgated
thereunder. Units issued by EOP Partnership generally are convertible into
common shares of Equity Office on a one-for-one basis, or the cash equivalent
thereof, at the election of Equity Office subject to certain restrictions.

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

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

(3) On December 19, 1997, EOP Partnership completed its acquisition of Beacon
    Partnership L.P. (the "Beacon Merger") at a cost of approximately $4.3
    billion. As a result of the Beacon Merger, EOP Partnership 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, EOP Partnership no longer adjusts for the amortization of
    discounts and premiums on mortgages when calculating Funds from Operations.

                                        24
<PAGE>   25

Accordingly, EOP Partnership restated the prior period data for comparative
purposes. EOP Partnership 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 EOP
     Partnership to incur and service debt, to make capital expenditures and to
     fund other cash needs. EOP Partnership 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 EOP Partnership.
     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 EOP
     Partnership's financial performance or to cash flow from operating
     activities, determined in accordance with GAAP, as a measure of EOP
     Partnership's liquidity, nor is it indicative of funds available to fund
     EOP Partnership'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,
    net gain (loss) on sales of real estate, gains (losses) from extraordinary
    items and income from investment in unconsolidated joint ventures plus EOP
    Partnership'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 EOP
    Partnership believes this data is used by some investors to evaluate EOP
    Partnership's ability to meet debt service requirements. EOP Partnership
    considers earnings before interest, taxes, depreciation and amortization to
    be an indicative measure of its operating performance due to the
    significance of EOP Partnership's long-lived assets and because this data
    can be used to measure EOP Partnership'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 EOP Partnership 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 EOP
    Partnership. Investors are cautioned that these excluded items are
    significant components in understanding and assessing EOP Partnership'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 EOP Partnership 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. 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 EOP Partnership has made assumptions are the following:

     - EOP Partnership's ability to successively integrate Cornerstone's
       operations into those of EOP Partnership;
     - 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;
     - EOP Partnership's ability to reduce various expenses as a percentage of
       revenues;
     - EOP Partnership's continuing ability to pay amounts due to its
       noteholders and preferred Unitholders before any distribution to holders
       of Units;
     - The cost to complete and lease-up pending developments;
     - EOP Partnership'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 EOP Partnership's customers for office-related services.

     During the year ended December 31, 2000, EOP Partnership completed the
following key transactions:

     - Acquired Cornerstone Properties Limited Partnership (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. EOP Partnership'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, of
     which EOP Partnership issued a corresponding number of Units to Equity
     Office on a one-to-one basis;

                                        26
<PAGE>   27

          (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;
          (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. EOP Partnership will pay approximately $1.085 billion in cash
and issue approximately 118.6 million new EOP Partnership units and 14.3 million
new EOP Partnership preferred units in the transaction. EOP Partnership intends
to finance the $1.085 billion cash portion of the purchase price using a
combination of available borrowing capacity under our existing credit facility,
a new bridge loan facility to be entered into before the closing of the merger
and/or through the issuance of senior unsecured notes.

     Following the Spieker Merger, EOP Partnership 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. EOP Partnership will also own 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 Spieker 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 Spieker Merger, which will be accounted for using purchase accounting,
is subject to the approval of the shareholders of Equity Office and Spieker and
the partners of EOP Partnership and Spieker Partnership, as applicable, and to
other customary conditions.

RESULTS OF OPERATIONS

GENERAL

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

     EOP Partnership 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 EOP Partnership's acquisition and disposition
activity since January 1, 1999. The buildings and total square feet shown
include Properties EOP Partnership 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, EOP Partnership effectively owned 92.7
million square feet of office space as of December 31, 2000.

data presented shows changes in revenues and expenses from period to period.
Therefore, EOP Partnership 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 EOP
Partnership 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.
EOP Partnership'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. EOP Partnership
also earned interest from property disposition proceeds held in escrow accounts.
The amounts in escrow will be utilized for property acquisitions or returned to
EOP Partnership.

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. EOP
Partnership 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 12
Office Properties in 1999.

</TABLE>

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 EOP Partnership 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 EOP Partnership's portfolio and additional expenses associated with being a
public company. During 1999, EOP Partnership made significant investments in its
information systems, including the hiring of additional personnel and
established a real estate services group. In addition, EOP Partnership 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 EOP Partnership's portfolio, it is also anticipated that
EOP Partnership 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. EOP Partnership 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, EOP Partnership 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) EOP Partnership received common stock and/or warrants to purchase common
    stock for allowing companies that provide telecommunication and other
    services access to EOP Partnership 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) EOP Partnership 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.

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. EOP Partnership's partnership agreement generally requires
EOP Partnership to distribute substantially all of the net cash from operations
each quarter and to make reasonable efforts to distribute to Equity Office
enough cash for it to meet the 95% distribution requirement. EOP Partnership
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. EOP
Partnership currently intends to continue to make, but has not contractually
bound itself to make, regular quarterly distributions to holders of Units and
preferred units. Subject to the foregoing, EOP Partnership has established
annual distribution rates as follows:

     - $1.80 per annum per Unit;
     - 8.98% per annum ($2.245 per unit) for each Series A Preferred Unit;
     - 5.25% per annum ($2.625 per unit) for each Series B Preferred Unit; and
     - 8.625% per annum ($2.15625 per unit) for each Series C Preferred Unit.

     Since EOP Partnership's anticipated distributions will not allow EOP
Partnership, using only cash from operations, to retire all of its debt as it
comes due, EOP Partnership 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

                                        35

spreads over LIBOR.

MORTGAGE DEBT

     As of December 31, 2000, total mortgage debt (excluding EOP Partnership'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. EOP Partnership'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

the Properties in good condition, maintenance of insurance on the Properties and
obtaining lender consent to material tenant leases.

LINES OF CREDIT

     During 1999, EOP Partnership had a $1.0 billion revolving credit facility
(the "$1.0 Billion Credit Facility"). The interest rate was based on EOP
Partnership'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 credit facility obtained in May
2000 (the "Line of Credit"). Concurrently with the Cornerstone Merger, EOP
Partnership borrowed $1.0 billion under the $1.0 Billion Credit Facility and
amended this facility into a term

                                        36

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, EOP
Partnership repaid the Term Loan and terminated the loan agreement. As a result,
EOP Partnership 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, EOP Partnership 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, EOP Partnership 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 EOP Partnership, 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.

     Equity Office has guaranteed the outstanding obligations under the Line of
Credit and the Term Loan.

(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 Equity Office 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. Upon exchange of a $1,000 note for Common
    Shares of Equity Office, EOP Partnership would issue a corresponding number
    of Units to Equity Office on a one-to-one basis.

     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

     EOP Partnership'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. EOP
Partnership 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 EOP
Partnership's outstanding debt (maturing at various times through 2029) has a
fixed interest rate, which minimizes the risk of fluctuating interest rates. EOP
Partnership 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.
EOP Partnership 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 payment to the WR Holders of
approximately $11.3 million on September 13, 1999. Any amounts paid by Equity
Office resulted in EOP Partnership making an equal payment to Equity Office. 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

                                        39
<PAGE>   40

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 partners' equity.

     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 result in EOP
Partnership making an equal payment to Equity Office and will be recorded as a
reduction in partners' capital. 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 partners' capital 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.

     EOP Partnership'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.

     EOP Partnership has several investments in marketable securities. If the
market price of these securities increases or decreases by 10%, EOP
Partnership'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, EOP Partnership 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 EOP Partnership from market price
fluctuations unless EOP Partnership 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 EOP Partnership'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 EOP Partnership'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

     EOP Partnership 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) EOP Partnership 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 EOP Partnership 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). EOP Partnership 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.

    EOP Partnership 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 EOP Partnership 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 of Equity Office 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, EOP Partnership 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 EOP Partnership'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 EOP Partnership'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 EOP Partnership'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. EOP Partnership'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, EOP Partnership 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. EOP
Partnership 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 EOP Partnership'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). EOP Partnership 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 EOP Partnership 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 EOP Partnership.

     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, EOP
    Partnership no longer adjusts for the amortization of discounts and premiums
    on mortgages when calculating Funds from Operations. Accordingly, EOP
    Partnership restated the prior period data for comparative purposes. EOP
    Partnership 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 EOP Partnership to
    incur and service debt, to make capital expenditures and to fund other cash
    needs. EOP Partnership 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 EOP

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

ITEM 8.  FINANCIAL STATEMENTS.

                         REPORT OF INDEPENDENT AUDITORS

The Partners of EOP Operating Limited Partnership

     We have audited the accompanying consolidated balance sheets of EOP
Operating Limited Partnership ("EOP Partnership") as of December 31, 2000 and
1999, and the related consolidated statements of operations, partners' capital
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
schedule are the responsibility of EOP Partnership's management. Our
responsibility is to express an opinion on these financial statements and
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 EOP Partnership
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.

                                                               Ernst & Young LLP

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 -- BUSINESS AND FORMATION OF EOP PARTNERSHIP

     As used herein, "EOP Partnership" means EOP Operating Limited Partnership,
a Delaware limited partnership, together with its subsidiaries, and the
predecessors thereof ("Equity Office Predecessors"). EOP Partnership is a
subsidiary of Equity Office Properties Trust ("Equity Office"), a Maryland real
estate investment trust, which 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"). EOP
Partnership 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's assets,
which include investments in joint ventures, are owned by, and substantially all
of its operations are conducted through EOP Partnership. Equity Office is the
general partner of EOP Partnership. 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, EOP Partnership 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

     The consolidated financial statements represent the financial condition and
results of EOP Partnership and its subsidiaries. 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 EOP
Partnership was used as the valuation basis for these transactions. The assets
acquired and liabilities assumed by EOP Partnership 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

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

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

<PAGE>   55

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

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

Interest Rate Protection Agreements

     EOP Partnership 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. EOP
Partnership 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 EOP Partnership's financial condition and results of
operations.

Deferred Revenue

     During 2000 and 1999, EOP Partnership 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

     EOP Partnership is not liable for federal taxes as the partners recognize
their proportionate share of EOP Partnership's income or loss in their tax
returns. 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. EOP Partnership 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 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
                                        55

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.

Minority Interests -- 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 partners' capital.

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, of
        which EOP Partnership issued a corresponding number of Units to Equity
        Office on a one-for-one basis;
        (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

NOTE 10 -- LINES OF CREDIT AND TERM LOANS

     On August 14, 1998, EOP Partnership completed a term loan agreement with
various financial institutions to provide EOP Partnership 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, EOP Partnership 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, EOP Partnership had a $1.0 billion credit facility (the "$1.0
Billion Credit Facility"). EOP Partnership 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 EOP Partnership'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, EOP
Partnership 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, EOP Partnership
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, EOP Partnership 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.

NOTE 10 -- LINES OF CREDIT AND TERM LOANS -- (CONTINUED)

     In January 2000, EOP Partnership 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 EOP Partnership, 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.

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. Upon exchange of
     a $1,000 note for Common Shares of Equity Office, EOP Partnership would
     issue a corresponding number of Units to Equity Office on a one-for-one
     basis. 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.

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.

---------------
(1) In 1999, Equity Office announced a share repurchase plan. During 1999,
    715,600 Common Shares were repurchased at an average share price of $23.14
    for approximately $16.6 million in the aggregate and were retired along with
    a corresponding number of Units. An additional 4,742,500 Common Shares were
    repurchased and retired, along with a corresponding number of Units, between
    January and February 2000 at an average share price of $25.27 for
    approximately $119.8 million in the aggregate. In February 2000, Equity
    Office suspended its share repurchase plan in anticipation of the
    Cornerstone Merger. Prior to the implementation of Equity Office's share
    repurchase plan, Equity Office repurchased 324,434 Common Shares, which
    resulted in EOP Partnership repurchasing an equivalent number of Units from
    Equity Office, and EOP Partnership repurchased approximately 1.2 million
    Units in a private transaction.

Ownership of EOP Partnership

     As of December 31, 2000 and 1999, Equity Office had a 1% general
partnership interest and an approximate 86.9% and 87.0% limited partnership
interest in EOP Partnership, respectively. The remaining limited partners had an
approximate 12.1% and 12.0% interest in EOP Partnership, respectively, and
consist of various individuals and entities that contributed their properties to
EOP Partnership in exchange for partnership interests and are represented by
42,060,891 Units and 34,203,912 Units, respectively, which are exchangeable on a
one-for-one basis into Equity Office's Common Shares.

     In regards to Equity Office, net proceeds from the various offerings of
Equity Office have been contributed by Equity Office to EOP Partnership in
return for Units, which results in an increased ownership percentage that Equity
Office has in EOP Partnership.

Preferred Units

     Equity Office has several series of preferred shares outstanding of which
EOP Partnership issued a corresponding number of preferred units to Equity
Office. Listed below is a summary of EOP Partnership's Preferred Units. The
Preferred Unit holders are entitled to receive, when and as authorized by EOP
Partnership, cumulative preferential cash distributions. EOP Partnership may
redeem the Preferred Units at certain dates in whole or in part at a cash
redemption price equal to the redemption preference plus all accrued unpaid
distributions to the date fixed for redemption.

(1) The Series B Preferred Shares are convertible at any time by the holder into
    Equity Office Common Shares at a conversion price of $35.70 per Common
    Share. Such conversion would require EOP Partnership to issue Units on a
    one-for-one basis to Equity Office. These shares are non-callable for five
    years with a mandatory call on February 15, 2008.

     In January 2000, EOP Partnership repurchased 6,000 Series A Cumulative
Redeemable Preferred Units and 37,100 Series C Cumulative Redeemable Preferred
Units at an average unit price of $20.66 for approximately $.9 million in the
aggregate and the units were retired. The difference between the unit repurchase
amount and the carrying amount of the preferred units was classified as a
preferred distribution in the statement of operations for the year ended
December 31, 2000.

    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 EOP Partnership 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, EOP Partnership 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 EOP Partnership 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 EOP Partnership and the leasing agent.

     On September 8, 2000, EOP Partnership 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, EOP
     Partnership 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, EOP Partnership 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) EOP Partnership 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 EOP Partnership.

(6) EOP Partnership 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 EOP Partnership 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). EOP Partnership
    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. EOP Partnership'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, EOP Partnership 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 EOP Partnership's, WI's and any
     unaffiliated party's share, to complete the developments is approximately
     $770.2 million. EOP Partnership'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 EOP Partnership.

(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, EOP Partnership 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, EOP Partnership 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.

     EOP Partnership 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.

     EOP Partnership 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, EOP Partnership owns
preferred shares of Capital Trust. Mr. Zell is Chairman of the Board of Capital
Trust.

Amounts Received from Related Parties

     Related parties of EOP Partnership, 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 EOP Partnership
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

     The following is a description of Equity Office's 1997 Share Option and
Share Award Plan, as amended, (the "Employee Plan"), which is included in the
financial statements because any Common Shares issued pursuant to the Employee
Plan will result in EOP Partnership issuing Units to Equity Office, on a
one-for-one basis.

                                        78

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

     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 of Equity Office. 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 of Equity Office 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 of Equity Office 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 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.

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

     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
grant date fair value of Options granted during 2000, 1999 and 1998 was $5.63,
$2.91 and $4.88, respectively.

     In addition, there were 555,100 Restricted Shares issued during 2000 and
380,000 Restricted Shares issued during 1998. The Restricted Shares vest over
three to five years. The Restricted Shares were valued at an average of $23.91
per share. The restricted shares vest 50% on the third anniversary of the grant
date, 25% on the fourth anniversary of the grant date and 25% on the fifth
anniversary of the grant date. The value of the Restricted Shares is amortized
to compensation expense on a straight-line basis and included in general and
administrative expenses.

NOTE 23 -- 401(K) PLAN

     Equity Office established the Equity Office Properties Trust Section 401(k)
Savings/Retirement Plan (the "401(k) Plan") was established to cover eligible
employees of EOP Partnership 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. EOP Partnership matches
dollar for dollar employee contributions to the 401(k) Plan up to 4% of the
employees' annual salary. In addition, EOP Partnership may elect to make a
discretionary profit sharing contribution. EOP Partnership 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

     EOP Partnership 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 EOP Partnership believes that the risk is not significant.

Environmental

     EOP Partnership, as an owner of real estate, is subject to various
environmental laws of federal and local governments. Compliance by EOP
Partnership with existing laws has not had a material adverse effect on EOP
Partnership's financial condition and results of operations, and management does
not believe it will have such an impact in the future. However, EOP Partnership
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 EOP Partnership nor any of its Properties is presently subject to
material litigation nor, to EOP Partnership's knowledge, is any litigation
threatened against EOP Partnership 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 EOP Partnership.

Insurance

     EOP Partnership 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 EOP
Partnership.

     EOP Partnership carries earthquake insurance on all of the Properties,
including those located in California, subject to coverage limitations which EOP
Partnership 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 EOP
Partnership 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.

Commitments

     In accordance with the agreement governing the investment in WRALP, EOP
Partnership 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, EOP Partnership
has guaranteed WRALP's line of credit, which has an outstanding balance of
approximately $18.1 million as of December 31, 2000.

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

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 EOP Partnership 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, EOP Partnership
has agreed not to sell such Properties in a taxable transaction for a period of
time as defined in their respective agreements, or EOP Partnership 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 result in EOP Partnership making an equal
payment to Equity Office and will be recorded as a reduction in partners'
capital. 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 partners'
capital 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,
EOP Partnership 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

$1.085 billion in cash and issue approximately 118.6 million new EOP Partnership

EOP Partnership intends to finance the $1.085 billion cash portion of the
purchase price using a combination of available borrowing capacity under our

     Following the Spieker Merger, EOP Partnership 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. EOP Partnership will also own Spieker's industrial
portfolio of approximately 13.5 million square feet and its development
properties totaling 1.7 million square feet.

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 Spieker Merger, which will be accounted for using purchase accounting,
is subject to the approval of the shareholders of Equity Office and Spieker and
the partners of EOP Partnership and Spieker Partnership, as applicable, and to
other customary conditions.

     6. On February 23, 2001, the mortgage note encumbering Wachovia was
