Arden Realty Limited Partnership 
 Notes to Consolidated Condensed Financial Statements
March 31, 2005
(unaudited)
 1. Organization and Basis of Presentation Organization The terms us, we and our as used in this report refer to Arden Realty Limited
Partnership. The term Arden Realty refers to Arden Realty, Inc. We are an operating partnership that owns, manages, leases, develops, renovates and acquires
commercial properties located in Southern California. Arden Realty, a real estate investment
trust, or REIT, is our sole general partner and, as of March 31, 2005, owned approximately 97.5% of
our common operating partnership units, or common OP Units. Arden Realty conducts substantially
all of its operations through us and our subsidiaries. Commencing with its taxable year ended
December 31, 1996, Arden Realty has operated and qualified as a REIT for federal income tax
purposes. As of March 31, 2005, our portfolio was comprised of 121 primarily suburban office properties,
consisting of 198 buildings with approximately 18.9 million net rentable square feet, including 8
properties and 12 buildings currently held for disposition. As of March 31, 2005, our operating
portfolio was 91.1% occupied excluding the 8 properties currently held for disposition. Including
these properties, our portfolio was 90.4% occupied. Arden Realtys interest in us entitles it to share in our cash distributions, and in our
profits and losses in proportion to its percentage ownership. Certain individuals and entities own
our remaining common OP Units, including Messrs. Ziman and Coleman, Arden Realtys Chairman and
Chief Executive Officer and President and Chief Operating Officer, respectively, together with
other entities and persons. Each limited partner holding common OP Units is entitled to cause us
to redeem the limited partners common OP Units for cash. We may, however, elect to exchange those
common OP Units for shares of Arden Realtys common stock on a one-for-one basis, subject to
certain limitations instead of paying cash. With each redemption or exchange of common OP Units,
Arden Realtys percentage interest in us will increase. As our sole general partner, Arden Realty generally has the exclusive power under our
partnership agreement to manage us and conduct our business, subject to limited exceptions. Arden
Realtys board of directors manages our affairs. Our existence as a limited partnership cannot be
terminated until 2096 without the approval of a majority of our partners or in connection with the
sale of all or substantially all of our assets, a business combination, a judicial decree or the
redemption of all the common OP Units held by our limited partners. We are a Maryland limited partnership. Arden Realty is a Maryland corporation. Arden
Realtys common stock is listed on the New York Stock Exchange under the symbol ARI. Basis of Presentation The accompanying consolidated financial statements include the accounts of Arden Realty, us
and our subsidiaries. All significant intercompany balances and transactions have been eliminated
in consolidation. We consolidate all entities for which we have controlling financial interest as measured by a
majority of the voting interest. For entities in which the controlling financial interest is not
clearly indicated by ownership of a majority of the voting interest, we would consolidate those
entities that we control by agreement. We would also consolidate all variable interest entities
for which we were the primary beneficiary. We and Arden Realty currently own 100% of all of our consolidated subsidiaries and we do not
have any unconsolidated investments. Interim Financial Data The accompanying consolidated condensed financial statements should be read in conjunction
with our 2004 Annual Report on Form 10-K, as amended, as filed with the Securities and Exchange
Commission. The accompanying financial information reflects all adjustments, which are, in our
opinion, of a normal recurring nature and necessary for a fair presentation of our financial
position, results of operations and cash flows for the interim periods. Interim results of
operations are not necessarily indicative of the results to be expected for the full year. 6

Reclassifications Certain prior year amounts on our consolidated balance sheets and consolidated statements of
income have been reclassified to confirm with the current year presentation for properties sold and
classified as held for disposition pursuant to SFAS 144. Recent Accounting Pronouncements In December 2004, the FASB issued Statement 123 (revised), Share-Based Payment (FAS
123(R)). FAS 123(R) requires that all share-based payments to employees, including grants of
employee stock options, are to be recognized in the income statement based on their fair values.
The new standard will be effective as of the beginning of the first fiscal year beginning after
June 15, 2005. The adoption of this statement is not expected to have a material effect on our
results of operations or financial condition. 2. Commercial Properties Property Dispositions Gross SalesPriceProperty

    Approximately $2.0 million of the acquisition price was funded through the issuance of 54,950
common operating partnership units at an average price of $37.27. We expect to finalize our purchase price allocations to the assets acquired and
liabilities assumed after our valuation procedures are completed, but no later than one year from

5. Interest Rate Hedge Agreements We have periodically entered into interest rate hedge agreements to effectively convert
floating rate debt into fixed rate debt or to remove the variability associated with forecasted
issuances of fixed rate debt. Net amounts received or paid under these agreements are recognized as
an adjustment to interest expense when such amounts are incurred or earned. Our objective in using
interest rate hedge agreements is to manage our exposure to interest rate movements. Statement of Financial Accounting Standards No. 133, Accounting for Derivative Instruments
and Hedging Activities (SFAS 133), as amended and interpreted, establishes accounting and
reporting standards for derivative instruments and for hedging activities. The accounting for
changes in the fair value of derivatives depends on the intended use of the derivative and the
resulting hedge accounting designation. Derivatives used to hedge the exposure to changes in the
fair value of an asset, liability, or firm commitment attributable to a particular risk, are
considered fair value hedges. Derivatives used to hedge the exposure to variability in expected
future cash flows, or other types of forecasted transactions, are considered cash flow hedges. For derivatives designated as fair value hedges, changes in the fair value of the derivative
and the hedged item related to the hedged risk are recognized in earnings. For derivatives
designated as cash flow hedges, the effective portion of changes in the fair value of the
derivative is initially reported in other comprehensive income (loss), outside of earnings and
subsequently reclassified to earnings when the hedged transaction affects earnings. We have used such agreements to fix the floating interest rate associated with $50 million of
the Wells Fargo unsecured line of credit and the entire $125 million balance of the unsecured term
loan. In conjunction with the extension of our $125 million unsecured term loan in February 2005,
we also entered into a series of interest rate swap agreements to fix the interest rate through the
extension period. Under these interest rate swap agreements, the interest rate on this loan is
effectively fixed at 5.29% from June of 2006 through May of 2007, 5.55% from June of 2007 through
November of 2008, 5.76% from December of 2008 through May of 2010 and 5.99% from June of 2010
through February of 2012. The fair value of the interest rate swaps designated as cash flow hedges
of the interest payments on the unsecured term loan and unsecured credit facility of $3.6 million
at March 31, 2005 has been deferred in accumulated other comprehensive loss on our balance sheet.
The estimated fair value of these interest rate hedge agreements are dependent on changes in market
interest rates and other market factors that affect the value of such agreements. Consequently,
the estimated current fair value may significantly change during the term of the agreements.
Changes in the fair value of these instruments will be deferred in other comprehensive loss and
will be subsequently reclassified into interest expense as the hedged interest payments occur. If
these derivatives were terminated before their maturity and the hedged debt instruments remained
outstanding, amounts deferred in other comprehensive loss related to the terminated derivatives
would be reclassified out of other comprehensive loss into interest expense as the hedged interest
payments occur. If the underlying debt related to these hedges were to be repaid prior to
maturity, any amounts deferred in other comprehensive loss related to these derivatives would be
immediately reclassified into current earnings. In August 2004, we settled $150 million of forward-starting swaps that we entered into in 2003
that were hedging the variability associated with a forecasted $200 million issuance of unsecured
senior notes. Associated with the settlement of these forward-starting swaps, we paid approximately
$500,000 to the swap counterparties. This amount had been deferred in other comprehensive income
and will be reclassified into interest expense as the hedged interest payments on the debt occur. In February 2005, we settled $300 million of forward-starting swaps that we entered into in
2004 that were hedging the variability associated with a forecasted $300 million issuance of
unsecured senior notes. Associated with the settlement of these forward-starting swaps, we paid
approximately $3.9 million to the swap counterparties. This amount had been deferred in other
comprehensive loss and will be reclassified into interest expense as the hedged interest payments
on the debt occur. In 2003, we also entered into reverse interest rate hedge agreements to float $100 million of
the fixed interest rate associated with the 7.00% senior unsecured notes due in November of 2007.
Under these reverse hedges, we will receive interest at a fixed rate of 7.00% and pay interest at a
variable rate averaging the six-month LIBOR in arrears plus 3.10%. The interest rate hedges mature
at the same time the notes are due. These hedges qualify as fair value hedges for accounting
purposes. Net semi-annual interest payments will be recognized as increases or decreases in
interest expense. The fair value of the interest rate hedges will be recognized on our balance
sheet and the carrying value of the senior unsecured notes will be increased or decreased by an
offsetting amount. At March 31, 2005, the fair value of our fair value hedges was an unrealized
loss of approximately $1.9 million and was reported in accounts payable and accrued expenses line
item on our balance sheet. The offsetting adjustment to the hedged debt was included in the
unsecured senior notes line item on our balance sheet. No hedge ineffectiveness was recognized on
our fair value hedging relationships. The estimated fair value of these interest rate hedge
agreements are dependent on changes in market interest rates and other market factors that affect
the value of such agreements. Consequently, the estimated current fair value may significantly
change during the term of the agreements. During the three months ended March 31, 2005 and 2004,
we recognized approximately $30,000 and $700,000, respectively, as a reduction of interest expense
related to our fair value hedges. 9

6. Partners Capital A common Operating Partnership unit, or common OP Unit, and a share of Arden Realtys common
stock have essentially the same economic characteristics as they share equally in our total net
income or loss and distributions. A common OP Unit may be redeemed for cash or, at our election,
for shares of Arden Realtys common stock on a one-for-one basis. During the three months ended March 31, 2005 and 2004, Arden Realty redeemed an aggregate of
5,000 and 16,000 common OP Units, respectively, for shares of Arden Realtys common stock. In conjunction with the acquisition of 707 Broadway (see footnote 3), we issued a total of
54,950 common OP Units for a total value of approximately $2.0 million issued as part of the
consideration to acquire the property. During the three months ended March 31, 2005 and 2004, Arden Realty issued a total of 338,234
and 1,023,304, respectively, common shares relating to exercises of stock options. On March 28, 2005, Arden Realty issued a total of 39,625 restricted stock awards to certain
key employees. Holders of these shares have full voting rights and will receive any dividends but
are prohibited from selling or transferring unvested shares. The fair market value on the date of
these grants for these shares was $34.49. These restricted shares vest equally on the anniversary
date of the awards over 3 years. We recorded approximately $2,000 of compensation expense during
the three months ended March 31, 2005 and will record compensation expense for these grants on a
straight-line basis over the respective vesting period. On January 19, 2005, we made a distribution of $0.505 per common operating partnership unit. 7. Income (Loss) from Taxable REIT Subsidiary Included in interest and other loss are the operating results of Arden Realtys taxable REIT
subsidiary, or TRS. Under the name of Next>edge, the TRS provides energy consulting services to
commercial real estate owners. The following is a breakdown of the components of interest and other

 8. Stock Option Plan Beginning on January 1, 2003, we adopted the provisions of SFAS No. 148, Accounting for
Stock-Based Compensation  Transition and Disclosure under which we began expensing the costs of
new stock options granted to employees by Arden Realty in 2003 in accordance with SFAS No. 123,
Accounting for Stock-Based Compensation. We used the Black-Scholes option valuation model to
estimate the fair value of the stock options granted. During the three months ended March 31, 2005
and March 31, 2004, we expensed approximately $9,000 of stock option based employee compensation
costs. The following table reflects pro forma net income and earnings per common operating
partnership unit had we elected to expense all options granted prior to 2003 assuming the fair

 10. Commitments and Contingencies We are presently subject to various lawsuits, claims and proceedings arising in the ordinary
course of business, none of which if determined unfavorably to us is expected to have a material
adverse effect on our cash flows, financial condition or results of operations. There were no
material changes in our legal proceedings during the three months ended March 31, 2005. 11. Subsequent Events On April 13, 2005, we acquired 5670 Wilshire, an approximate 408,000 square foot, 92% leased
office property located in Los Angeles County for approximately $93 million. In conjunction with
this acquisition, we assumed an approximate $51.5 million mortgage loan, with an interest rate of
8.5%, that matures in September of 2008. On
April 15, 2005, Arden Realty filed a Form 8-K with the
Securities and Exchange Commission outlining recent material
agreements entered into by us. Included in this report was
information regarding restricted shares granted to Arden Realtys directors and
senior executives, directors fees and retainers and approved
salaries for certain executives for 2005, and the provisions of a new
four-year Outperformance Plan through which certain executives can
receive equity or cash awards if returns generated for shareholders
are in excess of threshold amounts. On April 28, 2005, a 130,000 square foot tenant in San Diego County defaulted on their lease
agreement with us. Annual rents from this tenant are approximately $1.8 million. All outstanding
amounts for this tenant were fully reserved as of March 31, 2005. 11

Item 2. Managements Discussion and Analysis of Financial Condition and Results of Operations Overview The following discussion relates to our unaudited consolidated financial statements included
herein, which should be read in conjunction with the financial statements and related notes thereto
included elsewhere in this Form 10-Q and in our 2004 Annual Report on Form 10-K, as amended. This Form 10-Q, including the documents incorporated herein by reference, contains
forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E
of the Exchange Act pertaining to, among other things, our future results of operations, capital
resources, portfolio performance, cash available for distribution, acquisitions, lease renewals,
property development, property renovation, capital requirements, funds from operations, anticipated
market and demographic conditions and general business, industry and economic conditions applicable
to us. Forward-looking statements can be identified by the use of words such as may, will,
should, expect, anticipate, estimate, continue or comparable terminology. Although we believe the expectations reflected in any forward-looking
statements are based on reasonable assumptions, we can give no assurance that our expectations will
be attained. Forward-looking statements are inherently subject to certain risks, trends and
uncertainties, many of which we cannot predict with accuracy and some of which we might not even
anticipate. Future events and actual results, financial and otherwise, may differ materially from
the results discussed in the forward-looking statements. Factors that could cause actual results
to differ materially from our expectations include the availability and cost of capital for future
investments, our ability to lease or re-lease space at current or anticipated rents, changes in the
supply of and demand for our properties, changes in interest rate levels, risks associated with the
development, acquisition or disposition of properties, competition within the industry, real estate
and market conditions, and other risks detailed from time to time in our SEC filings. The risks
included here are not exhaustive, and additional factors could adversely affect our business and
financial performance, including risks and factors included in other sections of this Form 10-Q.
In addition, we discussed a number of material risks in our annual report on Form 10-K for the year
ended December 31, 2004. Those risks continue to be relevant to our performance and financial
condition. We also operate in a very competitive and rapidly changing environment. New risk
factors emerge from time to time and it is not possible for management to predict all such risk
factors, nor can it assess the impact of all such risk factors on our companys business or the
extent to which any factor, or combination of factors, may cause actual results to differ
materially from those contained in any forward-looking statements. Given these risks and
uncertainties, investors should not place undue reliance on forward-looking statements as a
prediction of actual results. In addition, we expressly disclaim any responsibility to update forward-looking statements,
whether as a result of new information, future events or otherwise. Accordingly, investors should
use caution in relying on past forward-looking statements, which are based on results and trends at
the time they were made, to anticipate future results or trends. We are a self-administered and self-managed real estate company that owns, manages, leases,
develops, renovates and acquires commercial properties located in Southern California. We are
managed by 6 senior executive officers who have experience in the real estate industry ranging from
14 to 35 years and who collectively have an average of 20 years experience. We perform all property
and development management, accounting, finance and acquisition, disposition activities and a
majority of our leasing transactions with our staff of approximately 300 employees. As of March 31, 2005, Arden Realty was Southern Californias largest publicly traded office
landlord as measured by total net rentable square feet owned. As of that date, our portfolio was
comprised of 121 primarily suburban office properties, consisting of 198 buildings with
approximately 18.9 million net rentable square feet, including 8 properties and 12 building
currently held for disposition. As of March 31, 2005, our operating portfolio was 91.1% occupied,
excluding the 8 properties currently held for disposition. Including these properties our
portfolio was 90.4% occupied. Our primary business strategy is to actively manage our portfolio to achieve gains in rental
rates and occupancy, control operating expenses and maximize income from ancillary operations and
services. When market conditions permit, we may also selectively develop, renovate or acquire new
properties in submarkets that add value and fit strategically into our portfolio. We may also sell
existing properties and use the net proceeds to repay outstanding indebtedness or place into
investments that we believe will generate higher long-term value. 12

RESULTS OF OPERATIONS Our financial position and operating results primarily relate to our portfolio of commercial
properties and income derived from those properties. Therefore, the comparability of financial data
from period to period will be affected by the timing of property developments, acquisitions and

    Property Operating Results is commonly used by investors to evaluate the
performance of real estate companies, to determine trends in earnings and to compute
the fair value of properties as it is not affected by (1) the cost of funds of the
property owner or (2) the impact of depreciation and amortization expenses as well as
gains or losses from the sale of operating real estate assets that are included in
net income computed in accordance with Generally Accepted Accounting Principles, or
GAAP. The first factor is commonly eliminated from net income because it is specific
to the particular financing capabilities and constraints of the owner. The second
factor is commonly eliminated because it may not accurately represent the actual
change in value in real estate properties that results from use or changes in market
conditions. We believe that eliminating these costs from net income gives investors
an additional measure of operating performance that, when used as an adjunct to net
income computed in accordance with GAAP, can be a useful 14

measure of our operating results.Property Operating Results captures trends in occupancy rates, rental rates and
operating costs. However, Property Operating Results excludes
general and administrative costs, interest expense, interest income, depreciation and
amortization expense and gains or losses from the sale of properties,
changes in value in our real estate properties that result from use or permanent impairment to
carrying costs as stipulated by GAAP, the level of capital
expenditures and leasing costs necessary to maintain the operating performance of our
properties, all of which are significant economic costs.
Therefore, Property Operating Results may fail to capture significant trends which limits its
usefulness.Property Operating Results is a non-GAAP measure of performance. Property Operating
Results is not a substitute for net income as computed in accordance with GAAP. It
excludes significant expense components such as depreciation and amortization expense
and financing costs. This measure should be analyzed in conjunction with net income
and cash flow from operating activities as computed in accordance with GAAP. Other
companies may use different methods for calculating Property Operating Results or
similarly entitled measures and, accordingly, our Property Operating Results may not be
comparable to similarly entitled measures reported by other companies that do not
define the measure exactly as we do.The following is a reconciliation of net income computed in accordance with GAAP to

    Consists of non-development properties classified as part of continuing operations
and owned for the entirety of the periods presented. VARIANCES FOR RESULTS OF OPERATIONS Our Property Operating Results for the three months ended March 31, 2005 compared to the same
period in 2004 were primarily affected by our acquisitions and development activities since January
1, 2004. As a result of these changes within our portfolio of properties since January 1, 2004, we do
not believe the Property Operating Results presented above are comparable from period to period.
Therefore, in the table above, we have also presented the Property Operating Results for our same
store portfolio. Revenue from Rental Operations Revenue from rental operations increased approximately $7.9 million, or 8% for the three
months ended March 31, 2005 compared to the same period in 2004. This increase was primarily due
to revenues from our 6100 Center Drive development property which was placed in service during the
second quarter of 2004, two office properties acquired in Los Angeles County in October of 2004
totaling approximately 391,000 square feet, two office properties acquired in San Diego County in
January of 2005 and March of 2005 totaling approximately 778,000 square feet and from overall
occupancy gains and scheduled rent increases in our properties. Revenue from rental operations for the same store portfolio increased approximately $1.2
million for the three months ended March 31, 2005 compared to the same period in 2004, primarily
due to an approximately $1.9 million increase in scheduled cash rents, partially offset by an
approximate $0.6 million decrease in other rental operations. The increase in scheduled cash rents
was primarily attributable to a 140 basis point increase in average occupancy and scheduled rent
increases in our existing leases. The decrease in other rental operations was primarily
attributable to lower lease termination fees in 2005. Property Expenses Property expenses increased approximately $3.1 million, or 10% for the three months ended
March 31, 2005 compared to the same period in 2004. This increase was primarily due to our
acquisition and development activities, gains in occupancy and increases in operating expenses for
the same store portfolio described below. Property expenses for the same store portfolio increased approximately $1.3 million, or 4% for
the three months ended March 31, 2005 compared to the same period in 2004, primarily due to higher
repairs and maintenance as a result of higher costs for contracted services and the timing of
certain projects. 15

##### Table of Contents



General and Administrative General and administrative expenses as a percentage of total revenues were approximately 8%
for the three months ended March 31, 2005 compared to approximately 4% for the same period in 2004.
The approximate $3.8 million increase in general and administrative expenses over 2004 was due to
an approximate $1.7 million in employee separation costs and $415,000 in dead-deal costs for a
proposed fee-development project. The remaining increase was primarily
due to a $500,000 increase in restricted stock expense related to grants made since the first
quarter of 2004, $450,000 increase in personnel costs related to annual merit increases and the
timing of bonuses and various other expenses incurred in the first quarter of 2005, including the
on-going Section 404 Compliance costs. Depreciation and Amortization Depreciation and amortization expense increased by approximately $3.6 million, or 13% for the
three months ended March 31, 2005 compared to the same period in 2004, primarily due to
depreciation related to a development property placed in service in the second quarter of 2004, two
properties acquired in October 2004, one property acquired in January 2005 and depreciation related
to capital expenditures, tenant improvements and leasing commissions placed in service in 2004 and
2005. Interest and Other Loss (Income) Interest and other loss (income) decreased by approximately $1.0 million for the three months
ended March 31, 2005 compared to the same period in 2004, primarily due to net income recognized
from a consulting and installation project completed during the first quarter of 2004 by
Next>edge, Arden Realtys taxable REIT subsidiary that provides energy consulting services. LIQUIDITY AND CAPITAL RESOURCES Cash Flows Cash provided by operating activities decreased by approximately $13.1 million to $30.8
million for the three months ended March 31, 2005 compared to $43.9 million for the same period in
2004. This decrease was primarily due to the loss of operating cash flows from thirteen properties
sold since the beginning of 2004 as part of our capital recycling program, partially offset by the
increased operating cash flows from four properties acquired since the beginning of 2004 and our
6100 Center Drive development property which was placed in service during the second quarter of
2004. Cash used in investing activities increased by approximately $279.5 million to an outflow of
$236.4 million for the three months ended March 31, 2005 compared to an inflow of $43.1 million for
the same period in 2004. This increase was primarily due to the acquisitions of two properties in
the first quarter of 2005 totaling approximately $233 million and the sale of two assets totaling
approximately $67.5 million in the first quarter of 2004. Cash provided financing activities increased by approximately $276.0 million to an inflow of
$196.1 million for the three months ended March 31, 2005 compared to an outflow of $79.9 million
for the same period in 2004. This increase was primarily due to the issuance of $300 million of
unsecured senior notes in February 2005. The proceeds from these notes were used to redeem $200
million of unsecured senior notes that matured in March of 2005 and to partially fund our
acquisition activities. Cash Balances and Available Borrowings As of March 31, 2005, we had approximately $18.4 million in cash and cash equivalents,
including $14.9 million in restricted cash. Restricted cash consisted of $5.2 million in interest
bearing cash deposits required by four of our mortgage loans payable and $9.7 million in cash
impound accounts for real estate taxes and insurance as required by several of our mortgage loans
payable. We have access to a total of $330 million under two unsecured lines of credit. As of March
31, 2005, $259.0 million was outstanding and $71.0 million was available under these unsecured
lines of credit. Capital Recycling Program Under our capital recycling program, we evaluate our existing portfolio of properties and
current market opportunities to determine if the sale or purchase of properties would improve the
overall quality or return on invested capital of our existing portfolio. Proceeds from sales of
properties may be used to pay down our borrowings until we identify attractive properties to
purchase, renovate or develop. During the three months ended March 31, 2005, we sold one property
totaling approximately 167,000 square feet for approximately $16.6 million in gross sales proceeds.
During the three months ended March 31, 2005, we acquired two office properties consisting of
approximately 778,000 square feet for approximately $233.0 million. For additional information
regarding the properties acquired and sold, see the accompanying notes to our financial statements
elsewhere in this report. 16

Consolidated Income Available for Debt Service and Compliance with Principal Financial
Covenants Consolidated Income Available for Debt Service is a non-GAAP measurement of our performance
and liquidity. Consolidated Income Available for Debt Service is presented below because this data
is used by investors and our management as a supplemental measure to (a) evaluate our operating
performance and compare it to other real estate companies, (b) determine trends in earnings, (c)
determine our ability to service debt and (d) determine our ability to fund future capital
expenditure requirements. As discussed more fully below, Consolidated Income Available for Debt
Service is also used in several financial covenants we are required to satisfy each quarter under
the terms of our principal debt agreements. Consolidated Income Available for Debt Service permits investors and management to view income
from our operations on an unleveraged basis before the effects of non-cash depreciation and
amortization expense. By excluding interest expense, Consolidated Income Available for Debt
Service measures our operating performance independent of our capital structure and indebtedness
and, therefore, allows for a more meaningful comparison of our operating performance between
quarters as well as annual periods and to compare our operating performance to that of other
companies, and to more readily identify and evaluate trends in earnings. The usefulness of Consolidated Income Available for Debt Service is limited because it does
not reflect interest expense, taxes, gains or losses on sales of property, losses on valuations of
derivatives, asset impairment losses, cumulative effect of a change in accounting principle,
extraordinary items as defined by GAAP and depreciation and amortization costs. These costs have
been or may in the future be incurred by us, each of which affects or could effect our operating
performance and ability to finance our investments at competitive borrowing costs, successfully
maintain Arden Realtys REIT status, and acquire and dispose of real estate properties at favorable
prices to us. Some of these costs also reflect changes in value in our properties that result from
use or changes in market conditions and the level of capital expenditures and leasing costs
necessary to maintain the operating performance of our properties. Due to the significance of the
net income components excluded from Consolidated Income Available for Debt Service, this measure
should not be considered an alternative to (and should be considered in conjunction with) net
income, cash flow from operations, and other performance or liquidity measures prescribed by GAAP.
This measure should also be analyzed in conjunction with discussions elsewhere in Managements
Discussion and Analysis of Financial Condition and Results of Operations regarding the items
eliminated in the calculation of Consolidated Income Available for Debt Service. The reader is cautioned that Consolidated Income Available for Debt Service, as calculated by
Arden Realty, may not be comparable to similar measures reported by other companies (under names
such as or similar to Consolidated Income Available for Debt Service, EBITDA or adjusted EBITDA)
that do not define this measure exactly the same as we do. 18

 Consolidated Income Available for Debt Service is also presented because it is used in
ratios contained in the principal financial covenants of the Indenture governing our publicly
traded senior unsecured notes and our Credit Agreement with a syndicate of banks led by Wells
Fargo. As of March 31, 2005, our senior unsecured notes represented approximately 51% of our total
outstanding debt and amounts outstanding under our Wells Fargo unsecured line of credit represented
approximately 16% of our total outstanding debt. The Consolidated Income Available for Debt
Service ratios and the other ratios reported below are part of financial covenants we are required
to satisfy each fiscal quarter. We believe information about these ratios is useful to (1) confirm
that we are in compliance with the financial covenants of our principal loan agreements, (2)
evaluate our ability to service our debt, (3) evaluate our ability to fund future capital
expenditures, and (4) compare our ratios to other real estate companies, including other real
estate companies, that present the same ratios. If we were to fail to satisfy these financial covenants, we would be in default under the
terms of the Indenture for the senior unsecured notes and/or the Wells Fargo Credit Agreement. A
default under those agreements could accelerate the obligation to repay such debt and could cause
us to be in default under our other debt agreements. Depending on the circumstances surrounding
such acceleration, we might not be able to repay the debt on terms that are favorable to us, or at
all, which would have a material adverse affect on our financial condition and our ability to raise
capital in the future. 19

    We believe that funds from operations, or FFO, is a useful supplemental measure
of our operating performance. We compute FFO in accordance with standards established
by the White Paper on FFO approved by the Board of Governors of the National Association
of Real Estate Investment Trusts, or NAREIT, in April 2002. The White Paper defines FFO
as net income or loss computed in accordance with generally accepted accounting
principles, or GAAP, excluding extraordinary items, as defined by GAAP, and gains and
losses from sales of depreciable operating property plus real estate-related
depreciation and amortization and after adjustments for unconsolidated partnerships and
joint ventures.We believe that FFO, by excluding depreciation costs, the gains or losses from the sale of
operating real estate properties and the extraordinary items as defined by GAAP, provides
an additional perspective on our operating results. However, because these excluded items
have a real economic effect, FFO is a limited measure of performance.FFO captures trends in occupancy rates, rental rates and operating costs. FFO excludes
depreciation and amortization costs and it does not capture the changes in value in our
properties that result from use or changes in market conditions or the level of capital
expenditures and leasing costs necessary to maintain the operating performance of our
properties, all of which are significant economic costs. Therefore, its ability to measure
performance is limited.Because FFO excludes significant economic components of net income determined in
accordance with GAAP, FFO should be used as an adjunct to net income and not as an
alternative to net income. FFO should also not be used as an indicator of our financial
performance, or as a substitute for cash flow from operating activities determined in
accordance with GAAP or as a measure of our liquidity. FFO is not by itself indicative of
funds available to fund our cash needs, including our ability to pay dividends or service
our debt.FFO is used by investors to compare our performance with other real estate companies.
Other real estate companies may use different methods for calculating FFO and,
accordingly, our FFO may not be comparable to other real estate companies.(2)
    
    Includes $519,000 and $746,000 in non-cash compensation expense for the three months
ended March 31, 2005 and 2004, respectively. 21

    Excludes tenants occupying the eight properties classified as held for
disposition at March 31, 2005. Including these properties, Ceridian, a 152,612 square
foot tenant with annualized base rent of $3.7 million, would rank as the third
largest tenant in the portfolio.(2)
    
    Annualized base rent is calculated as monthly contractual base rent under
existing leases as of March 31, 2005 multiplied by 12; for those leases where rent has
not yet commenced or which are in a free rent period, the first month in which rent is
to be received is used to determine annualized base rent.(3)
    
    The weighted average calculation is based on net rentable square footage leased
by each tenant. 23

Development / Renovation We completed the renovation of a 100,000 square foot building in Orange County which was
expanded to 130,000 square feet during the first quarter of 2005. We delivered the building in
February pursuant to a 10-year lease signed with an existing tenant. The year 1 cash yield on this
renovation is estimated at approximately 9.6% and 11.2% on a GAAP basis after including an
adjustment for straight-line rents. In addition,
we have preliminary architectural designs completed for additional build-to-suit
or multi-tenant projects at the Howard Hughes Center totaling approximately 475,000 net rentable square feet of
office space. We also have construction entitlements at the Howard
Hughes Center for a combination of up to 600
hotel rooms, apartments or condominiums. Build-to-suit projects consist of properties constructed to the tenants
specifications in return for the tenants long-term commitment to the property. Based on improving office trends in the West Los Angeles submarket
and lack of new office supply scheduled to be delivered in the
surrounding submarkets over the next 18-to-24 months, we intend to
begin constructing a 160,000 square foot multi-tenant office building
at our Howard Hughes Center later this year. We anticipate the
permitting process to take approximately 4-to-6 months and the
construction of the core and shell of the building an additional
18 months before the building is ready for occupancy. In addition to our development at the Howard Hughes Center, we have completed preliminary
designs and are marketing an approximate 170,000 square foot build-to-suit office building at our
Long Beach Airport Business Park. Also, as part of our Gateway Towers acquisition in August 2002,
we acquired a 5-acre developable land parcel in Torrance, California that we intend to market for a
build-to-suit office building. We currently do not intend to commence construction on these
projects until build-to-suit tenant leases are signed with terms allowing us to achieve yields
commensurate with the projects development risk. We expect to finance our development/renovation activities over the next 24 months through net
cash provided by operating activities, proceeds from asset sales, proceeds from our unsecured lines
of credit or other secured borrowings. 
 Item 3. Quantitative and Qualitative Disclosure about Market Risk Market risk is the exposure or loss resulting from changes in interest rates, foreign currency
exchange rates, commodity prices and equity prices. The primary market risk to which we are
exposed is interest rate risk, which is sensitive to many factors, including governmental monetary
and tax policies, domestic and international economic and political considerations and other
factors that are beyond our control. Interest Rate Risk In order to modify and manage the interest characteristics of our outstanding debt and limit
the effects of interest rates on our operations, we use a variety of financial instruments,
including interest rate swaps, caps, floors and other interest rate exchange contracts. The use of
these types of instruments to hedge our exposure to changes in interest rates carries additional
risks such as counter-party credit risk. We do not enter into any transactions for speculative or
trading purposes. During 2002, we entered into interest rate swap agreements fixing the interest
rates on variable debt with notional amounts totaling $175.0 million. In August 2004, we settled
$150 million of forward-starting swaps we entered into in 2003 in conjunction with a forecasted
$200 million issuance of unsecured senior notes. In 2003, we also entered into reverse interest
rate swap agreements to float $100 million of the fixed interest rate associated with the 7.00%
senior unsecured notes due in November 2007. In February 2005, we settled $300 million of forward-starting swaps we entered into in 2004 in
conjunction with a forecasted $300 million issuance of unsecured senior notes. In conjunction with the extension of our $125 million unsecured term loan in February 2005, we
also entered into a series of interest rate swap agreements to fix the interest rate through the
extension period. Under these interest rate swap agreements, the interest rate on this loan is
effectively fixed at 5.29% from June of 2006 through May of 2007, 5.55% from June of 2007 through
November of 2008, 5.76% from December of 2008 through May of 2010 and 5.99% from June of 2010
through February of 2012. Some of our future earnings, cash flows and fair values relating to financial instruments are
dependent upon prevailing market rates of interest, such as LIBOR. Based on interest rates and
outstanding balances as of March 31, 2005, a 1% increase in interest rates on our $309.0 million of
floating rate debt, including $100 million of fixed rate debt swapped to floating through interest
rate hedges, would decrease annual future earnings and cash flows by approximately $3.1 million and
would not have an impact on the fair value of the floating rate debt. Conversely, a 1% decrease in
interest rates on our $309.0 million of floating rate debt would increase annual future earnings
and cash flows by approximately $3.1 million and would not have an impact on the fair value of the
floating rate debt. The weighted average interest rate on our floating debt as of March 31, 2005
was 5.18%. Our fixed rate debt, including $175.0 million of floating rate debt swapped to fixed through
interest rate hedges, totaled $1,241.4 million as of March 31, 2005 with a weighted average
interest rate of 6.29% and a total fair value of approximately $1,227.3 million. A 1% decrease in
interest rates would increase the fair value of our fixed rate debt by approximately $61.2 million
and would not have an impact on future earnings and cash flows. A 1% increase in interest rates
would decrease the fair value of our fixed rated debt by approximately $57.2 million and would not
have an impact on future earnings and cash flows. 27

These amounts are determined by considering the impact of hypothetical interest rates on our
borrowing cost. These analyses do not consider the effects of the reduced level of overall
economic activity that could exist in that environment. Further, in the event of a change of this
magnitude, we would consider taking actions to further mitigate our exposure to the change. Due to
the uncertainty of the specific actions that would be taken and their possible effects, however,
this sensitivity analysis assumes no changes in our capital structure. 
 Item 4. Controls and Procedures We maintain disclosure controls and procedures that are designed to ensure that information
required to be disclosed in our Exchange Act reports is recorded, processed, summarized and
reported within the time periods specified in the SECs rules and forms, and that such information
is accumulated and communicated to our management, including Arden Realtys Chief Executive Officer
and Chief Financial Officer, as appropriate, to allow timely decisions regarding required
disclosure. In designing and evaluating the disclosure controls and procedures, our management was
required to apply its judgment in evaluating the cost-benefit relationship of possible controls and
procedures. Our disclosure controls and procedures are designed to provide a reasonable level of
assurance of reaching our desired disclosure control objectives. As required by SEC Rule 13a-15(b), we carried out an evaluation, under the supervision and
with the participation of our management, including Arden Realtys Chief Executive Officer and
Chief Financial Officer, of the effectiveness of the design and operation of our disclosure
controls and procedures as of the end of the first quarter of 2005 covered by this report. Based
on the foregoing, Arden Realtys Chief Executive Officer and Chief Financial Officer concluded that
our disclosure controls and procedures were effective and were operating at the reasonable
assurance level. There has been no change in our internal controls over financial reporting during our most
recent fiscal quarter that has materially affected, or is reasonably likely to materially affect,
our internal controls over financial reporting. 28
