    swaps for a payment of approximately $69.1 million and then
    entered into several fixed-to-floating interest rate swaps that
    effectively converted the 5.54% fixed interest rate on

    floating rate of LIBOR plus 122 basis points (which includes 79
    basis points for loan costs); and

|(e) |  | Based on annualized rent. Annualized rent is the monthly
    contractual rent as of the reporting date, or if the current
    rent payable is $0 then the first monthly rent payment due,
    under existing leases as of December 31, 2004 multiplied by
    12 months (Annualized Rent). This amount
    reflects total base rent and estimated expense reimbursements
    from tenants as of December 31, 2004 without regard to any
    rent concessions and contractual increases or decreases in rent
    subsequent to December 31, 2004. Total rent concessions for
    leases in place as of December 31, 2004, for the period
    from January 1, 2005 to December 31, 2005 are
    approximately $40.0 million. We believe Annualized Rent is
    a useful measure because this information can be used for
    comparison to current market rents as published by various third
    party sources.

| |  | We settled $800 million of forward-starting interest rate
    swaps for a payment of approximately $69.1 million and then
    entered into several fixed-to-floating interest rate swaps that
    effectively converted the 5.54% fixed interest rate on
    $1.0 billion of unsecured notes issued in March 2004 to a
    floating rate of LIBOR plus 122 basis points (which includes 79
    basis points for loan costs); and
|
| |  | settled five forward-starting interest rate swaps with a
    combined notional amount of $500 million resulting in a
    gain of approximately $24.0 million. The swaps were entered

    expected to take place in June 2004, but did not occur.

|(a) | These weighted average GAAP rental rates are based on the
    average annual base rent per square foot over the term of each
    lease and the current estimated tenant reimbursements, if any.                                                                                                                                                                                                                                                     
|   
|(b) | Weighted average annual rent per square foot for new office
    leases for tenants whose lease term commenced during the period
    may lag behind market because leasing decisions typically are
    made anywhere from one month to 12 or more months prior to
    taking occupancy.                                                                                                                                                              
|   
|(c) | These weighted average annual cash rental rates are based on the
    monthly contractual rent when the lease commenced, expired or
    terminated. For new and renewal leases, if the monthly
    contractual rent when the lease commenced is $0 then the rental
    rate represents the first monthly rent payment due multiplied by
    12 months (Annualized Cash Rent). This amount
    reflects total base rent and estimated current period

    commences. We believe Annualized Cash Rent is a useful measure
    because this information can be used for comparison to current
    market rents as published by various third party sources.

|    |  | the Americas. These two properties were encumbered by
    approximately $737.5 million of mortgage debt when they
    were consolidated. This increase was partially offset by
    $444.3 million of repayments.                                                                                                                                                                         
|(b) |  | The increase in unsecured notes and line of credit was due to
    the issuance of $2.1 billion of new notes and
    $214.0 million of net borrowings on the line of credit.
    These increases were partially offset by $1.2 billion of
    note repayments and additional discounts on the notes primarily
    due to mark-to-market adjustments on fair value interest rate
    swaps.
|(c) |  | The variable rate debt as of December 31, 2004 includes
    $1.0 billion of fixed rate unsecured notes that were
    converted to a variable rate based on LIBOR plus 122 basis
    points through several interest rate swap agreements entered
    into in March 2004. The interest rates for the remaining
    variable rate debt are based on various spreads over LIBOR.

|(a) |  | In July 2002, Equity Office announced a Common Share repurchase
    program allowing for the repurchase of up to $200 million
    of Common Shares in the open market or privately-negotiated
    transactions. This amount was later increased to
    $1.1 billion. Common Shares repurchased to fund Equity
    Offices employee benefit programs are not considered part
    of the repurchase program. During the year ended
    December 31, 2004, 1,413,230 Common Shares were repurchased
    at an average price of $26.19 for approximately
    $37.0 million in the aggregate. An additional 25,728 Common
    Shares were repurchased during December 2004 at an average price
    of $29.63 for approximately $0.8 million, but were not yet
    retired as of December 31, 2004 and are still outstanding.
    Since the inception of the program in 2002, Equity Office has
    repurchased approximately 23.6 million Common Shares at an
    average price of $25.37 for approximately $598.1 million.
    In connection with the repurchases under this program, we
    purchased from Equity Office and retired a corresponding number
    of Units for an aggregate cash purchase price equal to the
    aggregate purchase price for all Common Share repurchases.
|   
|(b) |  | During 2004, we issued Units in connection with the purchase of
    a partners interest in the 500 Orange office property. The
    total value of the Units was approximately $50,000.

|(a) | As of December 31, 2004 and 2003, the fair value of our
    fixed-rate debt was approximately $1.1 billion and
    $1.3 billion higher than the book value of approximately
    $10.9 billion and $11.1 billion, respectively,
    primarily due to the general decrease in market interest rates
    on secured and unsecured debt.

|(a) |  | FFO is a non-GAAP financial measure. The most directly
    comparable GAAP measure is net income, to which it is
    reconciled. See definition below.                                                                                                                                   
|   
|(b) |  | FFO per unit may not total the sum of the per unit components in
    the reconciliation due to rounding.                                                                                                                                                                                 
|   
|(c) |  | The Series B preferred units are not dilutive to EPS for
    each period presented and are not dilutive to FFO per unit for
    the year ended December 31, 2004 but are dilutive to FFO
    per unit for all other periods presented.                                                   
|   
|(d) |  | FFO per unit for the year ended December 31, 2004 includes
    a $229.2 million non-cash impairment charge, or $.51 per
    unit on a diluted basis, recorded in the third quarter 2004. By
    definition, impairment charges are not added back to net income
    when calculating FFO.

|(a) | As of January 1, 2004, our joint venture partners
    share of the mezzanine-level debt of approximately
    $49.7 million is recorded in other liabilities, which is
    net of a discount of approximately $31.5 million. Interest
    expense on the approximate $66 million face amount of the
    joint venture partners debt is accrued at 7.25% per
    annum and the discount is amortized to interest expense through
    the maturity of the mezzanine-level loan in 2014. The remaining
    debt of approximately $15 million does not accrue interest.

| | (a) Of the 71 industrial properties disposed of during
    2004, 29 were sold in a single transaction to an unrelated party
    for approximately $73.3 million in cash (before closing
    costs) and two office properties valued at approximately
    $137.0 million for total consideration of approximately
    $210.3 million (35% monetary/ 65% nonmonetary). The net
    book value of the 29 industrial properties sold was
    approximately $198.0 million. This transaction was
    accounted for as a like-kind exchange transaction which also
    included cash. Because the transaction included a monetary and
    nonmonetary component, we recognized a gain on sale of
    approximately $3.6 million on the monetary portion of the
    transaction. The nonmonetary portion of this transaction yielded
    no gain or loss. The remaining book value of the industrial
    properties, or approximately $130.0 million, represents the
    book value of the two office properties acquired in the
    transaction. The two office properties acquired are Commerce
    Plaza and Redstone Plaza, as further described in
    Note 4  Investments in Real Estate.

    properties (see Note 5  Sales of Real Estate).
    We account for our remaining investment in these properties
    under the equity method of accounting because we can exercise
    veto rights over certain significant policies.

|(a) | In June 2004, we launched a new program allowing for the
    issuance of up to $500 million of unsecured medium-term
    notes for sale to retail investors through licensed brokers
    (EOP InterNotes).

|(b) |  | The $45 million notes have a variable interest rate of
    LIBOR plus 77.5 basis points plus an additional
    10 basis points of loan costs. The $200 million notes
    have a variable interest rate of LIBOR plus 60 basis points
    plus an additional 13 basis points of loan costs.

|   
|(d) |  | In November 2004, we redeemed our 7.25% Senior Exchangeable
    Notes due November 15, 2008. The total paid on the
    redemption date was the principal amount of $325 million
    plus accrued interest. In conjunction with the redemption, we
    expensed approximately $5.3 million of unamortized loan
    costs which are included in amortization of deferred financing
    costs and prepayment expenses on the consolidated statements of
    operations.

|(f) |  | In March 2004, we entered into several interest rate swap
    agreements that effectively converted these notes to a variable
    interest rate based on the 6-month LIBOR rate (see
    Note 12  Derivative Financial Instruments).

| |  | We settled $500 million of forward-starting interest rate
    swaps and recognized a gain of approximately $24.0 million
    in May 2004, which is classified as realized gain on
    settlement of derivatives and sale of marketable
    securities on the consolidated statements of operations.
    The swaps were entered into in 2003 to hedge an unsecured note
    offering that was expected to occur in June 2004, but did not
    occur. The market value of these swaps at December 31, 2003
    represented an asset to us of approximately $11.1 million
    which was recorded in other assets with a corresponding
    adjustment to accumulated other comprehensive income.                                                                                                                                                                                                                                                                              
|
| |  | In conjunction with the issuance of $1.0 billion of 4.75%
    unsecured notes in March 2004 due March 2014, we paid
    $69.1 million to settle $800 million of
    forward-starting interest rate swaps that were previously
    entered into to hedge the interest rate of the $1.0 billion
    notes. Approximately $0.2 million of the settlement amount
    was immediately recognized in interest expense because the hedge
    was not perfectly effective and the remaining $68.9 million
    was recorded to accumulated other comprehensive income. The
    amount charged to accumulated other comprehensive income is
    being amortized to interest expense over the 10-year term of the
    hedged notes. The market value of these swaps at
    December 31, 2003 represented a liability to us of
    approximately $21.5 million which was recorded in other
    liabilities and a corresponding adjustment to accumulated other
    comprehensive income.
|
| |  | Approximately $6.8 million is expected to be reclassified

| | The joint venture redeveloped the Ferry Building in a manner to
    permit the use of federal rehabilitation tax credits
    (Historic Tax Credits). Since the original members
    of the joint venture could not take full advantage of the
    Historic Tax Credits, the joint venture admitted a new member
    who could do so. This investor member has contributed
    approximately $24.7 million in equity and will be entitled
    to a preferred return with an effective annual rate of
    approximately 3% on its capital investment. The investor
    members interest in the joint venture is subject to
    put/call rights during 2009 and 2010, the sixth and seventh
    years after the Ferry Building was placed in service in 2003.
    Upon the purchase of the investor members interest
    pursuant to the put/call, it is estimated that the joint venture
    will retain approximately $11 million of the capital
    contributed by the investor member, based on a formula to
    determine the purchase price for the investor members
    interest and after taking into account the preferred return that
    will have been paid to the investor member by such time. Through
    the creation of a master lease, our effective ownership
    percentage in the net cash flow of the Ferry Building project is
    approximately 100% after the payment to the Port of the
    percentage rent described above and the distribution of the
    preferred returns.

|(c) |  | In September 2004, we, together with a joint venture partner,
    acquired this vacant land parcel for approximately
    $10.9 million (our share of the purchase price was
    $7.6 million). The purchase price was paid with cash and a
    $2.7 million note that is payable on the date that
    construction commences on the land. We are a 70% partner in the
    joint venture and have control over major decisions.
    Accordingly, we consolidate this property. Our partners
    30% share of the joint venture is included in Minority
    Interests  Partially owned properties on the
    consolidated balance sheets.

| | Shares repurchased to fund our employee benefit programs are not
    considered part of the repurchase program. During the years
    ended December 31, 2004 and 2003, 1,413,230 and
    14,236,400 Common Shares were repurchased at an average
    price of $26.19 and $25.53 for approximately $37.0 million
    and $363.5 million in the aggregate, respectively. An
    additional 25,728 Common Shares were repurchased during
    December 2004 at an average price of $29.63 for approximately
    $0.8 million, but were not yet retired as of
    December 31, 2004 and are still outstanding. In conjunction
    with the repurchases under this program, we purchased from
    Equity Office and retired a corresponding number of Units for an
    aggregate cash purchase price equal to the aggregate purchase
    price for all Common Share repurchases.

|(a) |  | In July 2002, we issued 8,500,000 7.75% Series G
    Cumulative Redeemable Preferred Units to Equity Office in
    exchange for Equity Offices contribution of the proceeds
    of its issuance and sale of 8,500,000 7.75% Series G
    Cumulative Redeemable Preferred Shares in an offering that
    closed July 29, 2002. On that same date, substantially all
    of the net proceeds from the issuance of the Series G
    Preferred Units, totaling approximately $206.1 million were
    used to redeem the Series A Preferred Units from Equity
    Office and in turn, Equity Office used the proceeds to redeem
    its 7,994,000 outstanding 8.98% Series A Cumulative
    Redeemable Preferred Shares. In December 2003, the terms of the
    Series G Preferred Units were amended to require our
    consent to any redemption by Equity Office of these units.
|   
|(b) |  | In January 2004, Equity Office redeemed all of its
    4,562,900 outstanding
    85/8%
    Series C Cumulative Redeemable Preferred Shares of
    Beneficial Interest. The Series C Preferred Shares were
    redeemed at a redemption price of $25.00 per share for an
    aggregate redemption price of approximately $114.1 million.
    The deferred issuance costs of approximately $4.1 million
    were reflected as a preferred distribution. In connection with
    such redemption, we redeemed all of the Series C Preferred
    Units from Equity Office.                                                                                                                                                                                                                                                                                                          
|   
|(c) |  | In June 2003, Equity Office redeemed all of its
    6,000,000 outstanding 7.875% Series E Cumulative
    Redeemable Preferred Shares, which were issued in connection
    with the Spieker Merger, at a redemption price of
    $25.00 per share for an aggregate redemption price of
    approximately $151.9 million, which includes approximately
    $1.9 million of accrued and unpaid distributions. In
    connection with such redemption, we redeemed all of the
    Series E Preferred Units from Equity Office.

|    |  | We entered into a joint venture agreement with Wilson Investors
    in 2000 for the purpose of developing, constructing, leasing and
    managing developments in northern California. We own 49.9% of W/
    EO and Wilson Investors owns 50.1% of W/ EO. William
    Wilson III, through his ownership of Wilson Investors,
    indirectly owns approximately 22% of W/ EO and approximately 30%
    of any promote to which Wilson Investors is entitled under the
    joint venture agreement. We agreed to loan up to
    $25 million to Wilson Investors for its required
    contribution to W/ EO at a 15% interest rate per annum. In 2002,
    Wilson Investors repaid the outstanding loan balance of
    approximately $12.0 million of principal and approximately
    $2.0 million of accrued interest. Upon this repayment and
    as a result of certain transactions with Wilson Investors, the
    loan commitment was terminated. Our investment in W/ EO as of
    December 31, 2004 and 2003 was approximately
    $0.4 million and $1.3 million, respectively, which
    represents an indirect interest in Concar (a consolidated office
    property).                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
|   
|    |  | We created joint ventures with W/ EO and also, in certain cases,
    unaffiliated parties for the development of various office
    properties. We agreed to provide first mortgage financing to the
    ownership entities of each of these developments at the greater
    of 6.5% or LIBOR plus 3.25%, generally maturing 36 months
    after initial funding or earlier at our option, in the event
    alternative financing sources are available on terms reasonably
    acceptable to Wilson Investors and any unaffiliated party. The
    aggregate amount of any such financing would generally be capped
    at 70% of budgeted construction costs (76% in the case of Concar
    which, at December 31, 2002 had been completed and leased
    and as such is now reflected as investment in real estate). At
    December 31, 2002, we had committed to make mortgage loans
    for Foundry Square IV and Concar totaling approximately
    $96 million of which approximately $74 million in
    principal and approximately $0.4 million in accrued
    interest was outstanding. The total principal and interest
    outstanding on these mortgage loans at December 31, 2004
    and 2003 was approximately $40 million. The mortgage loan
    for Foundry Square IV was repaid in 2003 in connection with
    the sale of the property. Following this sale, W/ EOs sole
    asset is its ownership interest in Concar. In accordance with
    the W/ EO operating agreement, we may, but are not required to,
    purchase the W/ EO interest in Concar.                                                                                                                                                                                                                                                                                                                                  
|   
|    |  | In December 2002, we completed a transaction with W/EO and
    Wilson Investors pursuant to which we acquired W/EOs
    interests in various projects known as Foundry Square II,
    Foundry Square III (a land parcel that was under option),
    the Ferry Building, San Rafael Corporate Center I and
    San Rafael Corporate Center II (a land parcel). Wilson
    Investors acquired W/EOs interest in a project known as
    Larkspur (a land parcel under option) and Wilson Investors
    acquired the operating business and all assets of W/EO other
    than its ownership interests in the development projects known
    as Foundry Square IV and Concar. W/EOs and our
    interests in Foundry Square IV and Concar remained
    unchanged as a result of this transaction. Joint ventures with
    other unaffiliated parties on the projects in which we acquired
    W/EOs interest also remain unchanged as a result of this
    transaction. This transaction was accounted for as a nonmonetary
    exchange because the assets included in the exchange were
    similar and because the cash consideration exchanged was
    minimal. No gain or loss was recognized in connection with the
    transaction. A Wilson Investors subsidiary continued to provide
    the development management services to Foundry Square II,
    the Ferry Building and Concar through project stabilization. In
    2004, the final project reached stabilization and accordingly,
    the subsidiary of Wilson Investors has ceased providing
    development management services. We also engaged a subsidiary of
    Wilson Investors to provide leasing brokerage services for
    Foundry Square II and the Ferry Building. These services
    for Foundry Square II were terminated by us and these
    services for the Ferry Building were terminated in part by us in
    January 2004.

|(a) | We retain up to $75 million annual aggregate of such loss
    throughout the portfolio. In the event of a loss in excess of
    this retention limit, the third-party insurance carriers would
    be obligated to cover the losses up to the stated coverage
    amounts in the above table.

|(b) |  | The amount of the third party insurance relating to earthquakes
    is based on maximum probable loss studies performed by
    independent third parties. The maximum annual aggregate payment
    amount for earthquake loss is $325 million, inclusive of
    our loss exposure of $75 million plus $1 million per
    occurrence deductible. There can be no assurance that the
    maximum probable loss studies have accurately estimated losses
    that may occur.                                                                                                                                                                                                                                                                                                                                                                    
|   
|(c) |  | These amounts include our loss exposure/deductible amount.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
|   
|(d) |  | The coverage includes nuclear, chemical and biological events.
    The coverage does not apply to non-TRIA (Terrorism Insurance Act
    of 2002) events (which are terrorism events that are not
    committed by a foreigner or a foreign country). We maintain
    separate insurance with a $325 million annual aggregate
    limit subject to a deductible of $1 million for non-TRIA
    events. This separate coverage for non-TRIA events excludes
    nuclear, biological and chemical events. The Terrorism Insurance
    Act of 2002 will expire December 31, 2005 and there is a
    risk it will not be extended past this date. Should the act not
    be extended, the structure, terms or conditions (including
    premiums and coverage) of our terrorism insurance program would
    likely be affected for future periods.
|   
|(e) |  | This amount is in excess of our deductible amounts.
