|a) | We retain up to $75 million annual aggregate loss
    throughout the portfolio. In the event of a loss in excess of
    the per occurrence or annual aggregate amount, the third-party
    insurance carriers would be obligated to cover the losses up to
    the stated coverage amounts in the table above.                                                                                                                                                                                                                    
|  
|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 actual
    losses suffered in the event of an earthquake would not exceed
    the amount of such insurance coverage.                           
|  
|c) | These amounts include our loss exposure/deductible amount.                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
|  
|d) | This coverage includes nuclear, chemical and biological events
    under the Terrorism Risk Insurance Act of 2002
    (TRIA). This coverage does not apply to non-TRIA
    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.

| | TRIA established the Terrorism Risk Insurance Program
    (TRIP) to mandate that insurance carriers offer
    insurance covering physical damage from terrorist incidents
    certified by the U.S. government as foreign terrorist acts.
    Under TRIP, the federal government shares in the risk of loss
    associated with certain future terrorist acts. TRIA was extended
    for two years under the Terrorism Risk Insurance Extension Act
    (TRIEA), which established new requirements and
    expires on December 31, 2007. TRIEA created a new program
    trigger for any certified act of terrorism occurring after
    March 31, 2006 that prohibits payment of federal
    compensation unless the aggregate industry insured losses
    resulting from that act of terrorism exceed $50 million for
    2006 and $100 million for 2007. The trigger for federal
    reimbursement through March 31, 2006 is $5 million,
    rather than $50 million. The full interim guidelines
    established by the U.S. Treasury Department explaining
    these and other new requirements are available at
    www.treas.gov/trip. There can be no assurance that TRIEA will be
    further extended. Should such legislation not be extended, the
    premiums and scope of coverages for this program could be
    adversely affected.

| |  | Removal of trustees  Under Equity
    Offices declaration of trust, subject to the rights of one
    or more classes or series of preferred shares to elect one or
    more trustees, a trustee may be removed at any time, but only
    with cause, at a meeting of the shareholders by the affirmative
    vote of the holders of not less than a majority of the shares
    then outstanding and entitled to vote generally in the election
    of trustees.

| |  | Unsolicited takeover provisions of Maryland
    law  Maryland law provides protection for
    Maryland REITs against unsolicited takeovers by protecting the
    board of trustees with regard to actions taken in a takeover
    context. Maryland law provides that the duties of trustees will
    not require them to (a) accept, recommend or respond to any
    proposal by a person seeking to acquire control,
    (b) authorize the REIT to redeem any rights under, modify
    or render inapplicable a shareholder rights plan, (c) make
    a determination under the Maryland Business Combination Act or
    the Maryland Control Share Acquisition Act, or (d) act or
    fail to act solely because of the effect the act or failure to
    act may have on an acquisition or potential acquisition of
    control or the amount or type of consideration that may be
    offered or paid to shareholders in an acquisition. Maryland law
    also establishes a presumption that an act of a trustee
    satisfies the required standard of care. In addition, an act of
    a trustee relating to or affecting an acquisition or a potential
    acquisition of control is not subject under Maryland law to a
    higher duty or greater scrutiny than is applied to any other act
    of a trustee. Maryland law also provides that the duty of a
    trustee is only enforceable by the REIT or in the right of the
    REIT. A shareholder suit to enforce the duty of a trustee,
    therefore, can only be brought by or in the right of Equity
    Office.
|
| |  | Call of special meetings of shareholders 
    Equity Offices bylaws provide that special meetings of
    shareholders may be called only by the chairman of the board,
    the president, one-third of the trustees or by the holders of
    shares entitled to cast not less than a majority of all the
    votes entitled to be cast at the meeting. This provision limits
    the ability of shareholders to call special meetings.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
|
| |  | Advance notice provisions for shareholder nominations and
    shareholder new business proposals  Equity
    Offices bylaws require advance written notice for
    shareholders to nominate a trustee or bring other business
    before a meeting of shareholders. This provision limits the
    ability of shareholders to make nominations for trustees or
    introduce other proposals that are not timely received for
    consideration at a meeting.

| |   | the common shares without shareholder approval. The issuance of
    preferred shares could adversely affect the voting power of the
    holders of Equity Offices common shares and could be used
    to discourage, delay or prevent a change in control of Equity

| |  | Two-thirds shareholder vote required to approve many
    amendments to the declaration of trust  Under
    Maryland law and Equity Offices declaration of trust, the
    trustees, by a two-thirds vote, may at any time amend the
    declaration of trust solely to enable Equity Office to qualify
    as a REIT under the Internal Revenue Code or as a real estate
    investment trust under Maryland law, without action by Equity
    Office shareholders. Equity Offices board of trustees also
    may amend the declaration of trust to set the terms of one or
    more series of preferred shares without action by holders of
    Equity Office common shares. Other amendments to the declaration
    of trust must first be declared advisable by the board of
    trustees and thereafter must be approved by shareholders by the
    affirmative vote of not less than two-thirds of all votes
    entitled to be cast, or, in the case of amendments to the
    declaration of trust in connection with mergers and other
    specified business combinations or that involve an increase or
    decrease in the number of authorized common shares or preferred
    shares, not less than a majority of all votes entitled to be
    cast. The two-thirds shareholder vote requirement for many
    amendments to the declaration of trust may make amendments to
    the declaration of trust that shareholders believe desirable
    more difficult to effect.
|
| |  | Exclusive authority of board to amend bylaws, except for
    specified amendments  Equity Offices bylaws
    provide that the power to amend, repeal or adopt new bylaws is
    vested exclusively with the board of trustees, except that any
    amendments by the board of trustees to the bylaw provisions
    relating to meetings of shareholders, the size of the board, and
    the requirement that at least two-thirds of the trustees must be
    persons who are not executive officers of Equity Office or
    persons affiliated with Mr. Zell or his affiliates are
    subject to the approval of shareholders by vote of a majority of
    the votes cast. These provisions may make more difficult bylaw
    amendments that shareholders may believe are desirable.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
|
| |  | Business combination with interested
    shareholders  The Maryland Business Combination
    Act provides that, unless exempted, a Maryland REIT may not
    engage in business combinations, including mergers, dispositions
    of 10% or more of its assets, issuances of shares and other
    specified transactions, with an interested
    shareholder or its affiliates, for five years after the
    most recent date on which the interested shareholder became an
    interested shareholder and thereafter unless specified criteria
    are met. Equity Offices board of trustees has elected by
    resolution to exempt from the provisions of the Maryland
    Business Combination Act any business combination with any
    person. Equity Offices board of trustees may, however,
    repeal this election in whole or in part at any time and cause
    us to become subject to these provisions in the future, except
    with respect to a securityholder who became an interested
    shareholder in connection with our formation in July 1997.                                                                                                                                                                                                                                                                                                                                                                                                            
|
| |  | Other constituencies  Maryland law expressly
    codifies the authority of a Maryland REIT to include in its
    charter a provision that allows the board of trustees to
    consider the effect of a potential acquisition of control on
    shareholders, employees, suppliers, customers, creditors and
    communities in which offices or other establishments of the
    trust are located. Equity Offices declaration of trust
    does not include a provision of this type. Maryland law also
    provides, however, that the inclusion or omission of this type
    of provision in the declaration of trust of a Maryland REIT does
    not create an inference concerning factors that may be
    considered by the board of trustees regarding a potential
    acquisition of control. This law may allow the Equity Office
    board of trustees to reject an acquisition proposal even though
    the proposal was in the best interests of our unitholders.

|(e) |  | Annualized rent is the monthly contractual rent as of the
    reporting date under existing leases in which occupancy has
    commenced as of the reporting date multiplied by 12 months
    (Annualized Rent). If the current rent payable is $0
    (as a result of rent abatements), then the first monthly rent
    payment due under the existing lease is used to calculate
    annualized rent. The contractual rent amounts include total base
    rent and estimated expense reimbursements from tenants as of the
    reporting date before any adjustments for rent abatements and
    contractual increases or decreases in rent subsequent to
    December 31, 2005. Total rent abatements for leases in
    which occupancy has commenced as of the reporting date for the
    period from January 1, 2006 to December 31, 2006 are
    approximately $30.8 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.

|(a) | The number of Units purchased is comprised of the redemption of
    Units held by our limited partners, excluding Equity Office.
    Units redeemed in exchange for Common Shares are not considered
    a repurchase and are, therefore, excluded from the table above.
    At any time on or after the first anniversary of the date of
    issuance, our limited partners have the right to require EOP
    Partnership to redeem their Units, subject to certain
    limitations. Equity Office, on behalf of and as the general
    partner of EOP Partnership, has the right to cause the
    redemption obligation to be satisfied by issuance of an
    equivalent number of Common Shares, or by a cash payment equal
    to the value of such Common Shares. Also included in the total
    number of Units purchased are Units redeemed in response to
    repurchases made by Equity Office, including repurchases of
    Equity Office Common Shares in the open market (a) as part
    of its Common Share Repurchase Program, (b) as part of its
    Supplemental Retirement Savings Plan, (c) to fund shares
    purchased under its 1997 Employee Share Purchase Plan and
    (d) to fund fees paid in Equity Office Common Shares to
    each of its non-employee trustees, except Mr. Zell, as well
    as Equity Office Common Shares surrendered to Equity Office to
    satisfy withholding obligations in connection with the vesting
    of restricted stock issued to employees.

|(a) | On July 2, 2001, we completed our acquisition by merger of
    Spieker Properties, L.P. (Spieker) at a cost of
    $7.2 billion. As a result, we acquired 391 office
    properties containing 28.3 million square feet and 98
    industrial properties containing 10.1 million square feet.                                                                                                                 
|   
|(b) | These amounts include continuing and discontinued operations and
    also include our share of unconsolidated joint ventures.                                                                                                                                                                                                                                                                                   
|   
|(c) | These amounts represent property operating revenues (which
    include rental revenues, tenant reimbursements, parking and
    other operating revenues) less property operating expenses
    (which include real estate taxes, insurance, repairs and
    maintenance and property operating expense). See
    Item 8  Note 19 on why we present property
    net operating income from continuing operations.
|   
|(d) | These amounts include continuing and discontinued operations
    after allocations to minority interest partners and also include
    our share of unconsolidated joint ventures.                                                                                                                                                                                                                               
|   
|(e) | Refer to Item 7 for information regarding why we present
    funds from operations and for a reconciliation of this non-GAAP
    financial measure to net income.

|(b) | Weighted average annual rent per square foot for new leases for
    tenants whose lease term commenced during the period may lag the
    market because leasing decisions typically are made one month to
    12 or more months prior to taking occupancy.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
|   
|(c) | Based on the monthly contractual rent when the lease commenced,
    expired or terminated multiplied by 12 months. For new and
    renewal leases, if the monthly contractual rent when the lease
    commenced is $0 (as a result of rent abatements), then the
    rental rate represents the first monthly rent payment due
    multiplied by 12 months (Annualized Cash Rent).
    The contractual rent amounts include total base rent and
    estimated expense reimbursements from tenants before any
    adjustments for rent abatements and contractual increases or
    decreases in rent. 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.

|(a) | Corporate general and administrative expense is not allocated to
    the Same Store Portfolio because these expenses are not directly
    incurred in connection with any specific property.

|(b) | Interest expense (including amortization of deferred financing
    costs and prepayment expenses) for the Same Store Portfolio
    represents interest expense on mortgage debt and does not
    include interest expense on the unsecured notes or the lines of
    credit.

|(c) | Property net operating income consists of property operating
    revenues minus property operating expenses. Included in property
    operating revenues are rental revenue, tenant reimbursements,
    parking and other income, which includes income from early lease
    terminations. Included in property operating expenses are real
    estate taxes, insurance, repairs and maintenance and property
    operating expenses. See Item 8  Note 19 for
    more information.
|

|(a) | The variable rate debt as of December 31, 2004 included
    $1.0 billion of fixed rate unsecured notes that were
    converted to variable rate through several interest rate swaps
    entered into in March 2004. These swaps were terminated at
    various times during 2005. The interest rates for the remaining
    variable rate debt are based on various spreads over LIBOR.

|(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) | The Series B preferred units are not dilutive to EPS for
    each period presented and are not dilutive to FFO per Unit for
    the years ended December 31, 2005 and December 31,
    2004 but are dilutive to FFO per Unit for all other periods
    presented.

|(c) | FFO for the years ended December 31, 2005,
    December 31, 2004, December 31, 2003 and
    December 31, 2001 includes approximately
    $426.0 million, $231.3 million, $7.5 million and
    $135.2 million, respectively, of non-cash charges relating
    to properties sold and properties we intend to sell, which is
    equivalent to $0.94 per Unit, $0.51 per Unit,
    $0.02 per Unit and $0.32 per Unit on a diluted basis,
    respectively. These 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 $49.7 million is
    recorded in other liabilities, which is net of a discount of
    $31.5 million. Interest expense on the $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 $15 million does not
    accrue interest.

    comprising 1,020,000 square feet, is classified as a
    development property and, therefore, is not included in the
    total number of buildings or total square footage statistics.

|(g) |  | In October 2005, we invested $50.0 million in junior
    mezzanine debt as part of a debt refinancing on the 375 Park
    Avenue property located in New York, NY. The mezzanine debt
    bears interest at a rate of 8.95% and matures in 2015. We
    account for this investment as a note receivable, which is
    included in Prepaid expenses and other assets on the
    consolidated balance sheet.

|(h) |  | In 2004, we acquired certain partners interests in 1301
    Avenue of the Americas for $68.2 million and we assumed our
    partners share of the mortgage notes of
    $83.0 million. This property was previously accounted for
    under the equity method. As a result of these transactions, our
    economic interest in the joint venture is 100% and effective
    February 2004, we consolidated the property. The mortgage debt
    encumbering this property upon consolidation was
    $534.3 million.

|(i) |  | In May 2004, we acquired our partners interest in the 500
    Orange office property by issuing 1,930 Units valued at $50,000.

    acquired the office space, except for the fourth floor.                                                                                                                                                                                                                                                                                                                                                                                              
|   
|(l) |  | These properties were acquired through a like-kind exchange
    transaction in which we disposed of certain industrial
    properties (see Note 5  Gains/ Losses on Sales
    of Real Estate, Provisions for Loss on Assets Held for Sale and
    Impairments).                                                                                                                                                                                                                                                    
|   
|(m) |  | In December 2004, we acquired our partners 12.5% interest
    in Foundry Square II for $2.7 million. Following this
    transaction, we owned 100% of this property. We subsequently
    sold this property in 2005.

|(n) |  | In September 2004, we acquired a 70% interest in Dulles Station
    for $7.6 million. We subsequently sold our interest in this
    joint venture in 2005 (see Note 14  Minority
    Interests in Partially Owned Properties).                                                                                                                                                                                                                                                                                                                                                                                                       
|   
|(o) |  | In May 2003, we acquired 8.1% of the equity in the joint venture
    that owns The John Hancock Complex in Boston, Massachusetts for
    $25.0 million. The investment in the joint venture is
    accounted for under the cost method of accounting because we own
    a noncontrolling interest in the property. Our investment is
    included in Prepaid expenses and other assets in the
    consolidated balance sheets. In 2005, we received
    $17.3 million of cash proceeds from additional mortgage
    financing placed on this property, which effectively reduced our
    book basis investment in the joint venture.
|   
|(p) |  | In September 2003, we acquired the remaining 20% equity interest
    in Key Center from Wright Runstad Associates Limited Partnership
    (WRALP) and affiliates in exchange for our 30%
    equity interest in WRALP and a cash payment by us of
    $7.9 million. This property was previously accounted for
    under the equity method. As a result of this acquisition,
    effective September 2003, we consolidated the property.

|(a) |  | The number of buildings sold during the years ended
    December 31, 2005, 2004 and 2003 exclude the sale of
    partial interests in two buildings, two buildings, and 13
    buildings, respectively.                                                                                                                                                                                                                                                 
|   
|    |  | The number of buildings and square feet sold during the year
    ended December 31, 2005 excludes eight buildings comprising
    0.2 million square feet relating to properties previously
    taken out of service, which were no longer included in building
    and square footage statistics. Properties taken out of service
    represent office properties we are no longer attempting to lease
    and may be sold in the future or redeveloped.
|   
|    |  | The sales price shown for the year ended December 31, 2003
    also includes the disposition of 32 residential units,
    which are excluded from the number of buildings shown above.                                                                                                                                                                                                                                                                  
|   
|(b) |  | During the year ended December 31, 2004, we sold our 3%
    interest in an office property that we accounted for under the
    cost method. This property is excluded from the number of
    buildings and square feet shown above.                                                                                                                                                                                                                     
|   
|(c) |  | Of the 71 industrial properties disposed of during 2004, 29 were
    sold in a single transaction to an unrelated party for
    $73.3 million in cash (before closing costs) and two office
    properties valued at

| |  | $137.0 million for total consideration of
    $210.3 million (35% monetary/65% nonmonetary). The net book
    value of the 29 industrial properties sold was
    $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 $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 $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.

|(a) |  | In 2005, we sold our 25% interest in Chase Center (fka Bank One
    Center), which consisted of two office buildings comprising
    1,057,877 square feet, for $45.0 million (which
    includes the transfer of $16.3 million of mortgage debt
    encumbering this property to the buyer).

|(b) |  | In December 2005, the joint venture refinanced the mortgage debt
    encumbering the SunTrust Center. The new mortgage debt has a
    principal balance of $77.0 million, bears interest at a
    fixed coupon rate of 5.34% and matures in January 2016. Our
    share of the principal balance is $19.3 million. Our share
    of the prior mortgage, which bore interest at a variable rate
    based on LIBOR plus 80 basis points, was $12.5 million.

|(e) |  | In July 2004, we acquired a 50% interest in Yahoo! Center for
    $221.8 million. In 2005, the joint venture obtained a
    $250 million mortgage financing, which bears interest at a
    fixed coupon rate of 5.27% and matures in October 2015. Our
    share of the principal balance is $125.0 million.

|(f) |  | In November 2004, we sold partial interests in these office
    properties for $172.2 million. We account for our remaining
    interest under the equity method of accounting because we have
    participating rights with respect to certain significant
    policies.

|(h) |  | In 2000, we formed a joint venture with Wilson Investors to
    develop, construct, lease and manage Foundry Square IV, a
    225,490 square foot office building located in
    San Francisco, California. Through the sale of the office
    building in July 2003, we disposed of our 40% indirect interest.
    Our share of the gain on the sale of the property was
    $7.1 million and is included in income from investments in
    unconsolidated joint ventures. Our share of the gross proceeds
    from the sale was $56.6 million, which includes the
    repayment of a $44.5 million construction loan. Wilson
    Investors share of the proceeds was $17.1 million.

|(b) | This amount represents the aggregate difference between the
    Companys historical cost basis and the basis reflected at
    the joint venture level, which is typically amortized over the
    life of the related asset. The basis differentials occur
    primarily upon the transfer of assets that were previously owned
    by the Company into a joint venture or the acquisition of
    partial interests in joint ventures by us.

| |  | Prior to the disposition of the San Felipe Plaza property
    in 2005, the property was encumbered by a 5.81% mortgage note
    with an outstanding principal balance of $47.8 million that
    was scheduled to mature in 2013. The lender agreed to substitute
    the 1300 North 17th Street property, located in Arlington,
    Virginia, as replacement collateral. As a result, no prepayment
    penalty was incurred. The terms of the mortgage note were
    otherwise unchanged as a result of this transaction. In December
    2005, we obtained additional mortgage financing on the 1300
    North 17th Street property. This additional mortgage has a
    principal balance of $32.1 million, bears interest at a
    fixed coupon rate of 6.03% and an effective interest rate of
    6.07%. The mortgage matures in January 2013.

|(d) |  | In March 2004, we entered into four interest rate swaps that
    each had a notional amount of $250 million for a combined
    notional amount of $1 billion that effectively converted
    these notes to a variable interest rate based on the
    6-month LIBOR rate. One
    of the interest rate swaps was terminated during June 2005 and
    the remaining swaps were terminated in September 2005. The
    termination of the swaps effectively converted the notes back to
    a fixed interest rate (see Note 12  Derivative
    Financial Instruments).

|(e) |  | 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). The rates shown are weighted
    average rates. The coupon rates on the EOP InterNotes range from
    3.30% to 5.25%. Including all offering expenses, the all-in
    effective rates of the EOP InterNotes range from 3.61% to 5.46%.

| |  | In May 2004, we settled five forward-starting interest rate
    swaps with a combined notional amount of $500 million and
    recognized a gain of $24.0 million, 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 of
    $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 four forward-starting interest rate
    swaps that had a combined notional amount of $800 million
    that were previously entered into to hedge the interest rate of
    the $1.0 billion notes. $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 charged 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 of
    $21.5 million which was recorded in other liabilities and a
    corresponding adjustment to accumulated other comprehensive
    income.
|
| |  | $6.8 million will be reclassified from accumulated other
    comprehensive income to interest expense in 2006 related to
    amortization of net payments on settlements of forward starting
    interest rate swaps.

| | 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 contributed
    $24.7 million in equity and is entitled to a 3% preferred
    return. This investor members interest is subject to
    put/call rights during 2009 and 2010. Upon the purchase of the
    investor members interest pursuant to the put/call, it is
    estimated that the joint venture will retain $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
    100% after the payment to the Port of the percentage rent
    described above and the distribution of the preferred returns.

| |  | 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). At December 31, 2002, we had committed to make
    mortgage loans for Foundry Square IV and Concar totaling
    $96 million of which $74 million in principal and
    $0.4 million in accrued interest was outstanding. 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 was its ownership interest in Concar.
    The total principal and interest outstanding on the mortgage
    loans at December 31, 2004 and 2003 was $40 million,
    which was repaid in 2005 in connection with the sale of Concar.

| |  | A Wilson Investors subsidiary provided development management
    services to the Foundry Square II, Ferry Building and
    Concar properties 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. As of December 31,
    2003, $0.3 million was payable to Wilson Investors in
    relation to such services. 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.

|(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 actual
    losses suffered in the event of an earthquake would not exceed
    the amount of such insurance coverage.                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
|   
|(c) |  | These amounts include our loss exposure/deductible amount.

|(d) |  | This coverage includes nuclear, chemical and biological events
    under the Terrorism Risk Insurance Act of 2002
    (TRIA). This coverage does not apply to non-TRIA
    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.                                                                                                                                                                                                                                                                                                                                                                                                                                          
|   
|    |  | TRIA established the Terrorism Risk Insurance Program
    (TRIP) to mandate that insurance carriers offer
    insurance covering physical damage from terrorist incidents
    certified by the U.S. government as foreign terrorist acts.
    Under TRIP, the federal government shares in the risk of loss
    associated with certain future terrorist acts. TRIA was extended
    for two years under the Terrorism Risk Insurance Extension Act
    (TRIEA), which established new requirements and
    expires on December 31, 2007. TRIEA created a new program
    trigger for any certified act of terrorism occurring after
    March 31, 2006 that prohibits payment of federal
    compensation unless the aggregate industry insured losses
    resulting from that act of terrorism exceed $50 million for
    2006 and $100 million for 2007. The trigger for federal
    reimbursement through March 31, 2006 is $5 million,
    rather than $50 million.

|(e) |  | This amount is in excess of our deductible amounts.

| | 1. | We redeemed 2.3 million Units at an average purchase price
    of $30.48 per Unit for $69.0 million. In addition,
    Equity Office repurchased 13.0 million Common Shares under
    its open market repurchase program at an average purchase price
    of $31.49 per share for $408.6 million.                                                                                                                                                                                                            
|
| | 2. | In January 2006, we exercised our option to draw an additional
    $250 million on our $750 million term loan, which
    increased the amount outstanding under the facility to
    $1.0 billion. As of March 8, 2006, we also had
    $478 million outstanding under our $1.25 billion
    revolving credit facility.                                                                                                                                                                                      
|
| | 3. | On February 28, 2006, we obtained a $500 million
    unsecured term loan facility, which we fully drew upon on
    March 8, 2006. The loan matures in February 2007 and bears
    interest at the higher of the Prime Rate or the federal funds
    rate plus 50 basis points; plus a spread of 55 basis
    points (the spread is subject to change based on our credit
    rating). The proceeds from this loan will primarily be used to
    repay unsecured notes scheduled to mature on March 15, 2006.

| | 6. | During February 2006, the ownership structure of the Sixty State
    Street property was restructured. Pursuant to this restructure,
    we converted our former debt position in this property into an
    approximate 95% equity interest. In addition, new mortgage
    financing was obtained on the property. The new mortgage loan
    has a principal balance of $180.0 million, bears interest
    at a fixed coupon rate of 5.629% and matures on March 1,
    2011. Following this restructure, we will continue to
    consolidate the financial position and results of operations of
    this property because we continue to control the property.

| | 7. | We collected the $66.3 million note receivable related to
    the One Phoenix property that was sold in 2005 and recognized
