PART I

ITEM 1. BUSINESS

(A) GENERAL

The terms "Arden Realty", "us", "we" and "our" as used in this report refer
to Arden Realty, Inc. We were incorporated in Maryland in May 1996 and formed to
continue and expand the real estate business of Arden Realty Group, Inc. and a
group of affiliated entities, collectively referred to as the Arden
Predecessors. We completed our initial public offering in October 1996.
Commencing with our taxable year ended December 31, 1996, we have operated and
qualified as a real estate investment trust, or REIT, for federal income tax
purposes.

We are a self-administered and self-managed REIT, that owns, manages,
leases, develops, renovates and acquires commercial properties located in
Southern California. We are the sole general partner of Arden Realty Limited
Partnership, or the Operating Partnership and, as of December 31, 1999, owned
96.7% of the Operating Partnership's common partnership units. We conduct
substantially all of our operations through the Operating Partnership and its
subsidiaries.

(B) INDUSTRY SEGMENTS

We are currently involved in only one industry segment, namely real estate.
All of the financial information contained in this report relates to this
industry segment.

(C) DESCRIPTION OF BUSINESS

We are a full-service real estate organization managed by 11 senior
executive officers who have an average of 16 years of experience in the real
estate industry. We perform all property management, accounting, finance and
acquisition activities and a majority of our leasing transactions with our own
staff of approximately 280 employees.

We are Southern California's largest publicly traded office landlord as
measured by total net rentable square feet owned, as of December 31, 1999. Since
our formation in 1996, we have acquired 118 properties containing approximately
14.5 million net rentable square feet for a total purchase price of
approximately $1.9 billion. As of December 31, 1999, our portfolio consisted of
142 primarily office properties containing approximately 18.5 million net
rentable square feet and three properties with approximately 700,000 net
rentable square feet under development. As of December 31, 1999, our properties
were approximately 95.1% leased, excluding three existing properties under
renovation.

Portfolio Management

We perform all portfolio management activities, including management of all
lease negotiations, tenant build-outs, property renovations, capital
expenditures and on-site property management for our portfolio. We directly
manage these activities from approximately 45 management offices located
throughout our portfolio. The activities of these management offices are
supervised by five regional offices with oversight by our corporate office to
ensure consistency of the application of our operating policies and procedures.
Each regional office is strategically located within the Southern California
submarkets where our properties are located and is co-managed by a regional
property manager and a regional leasing manager who are responsible for
supervising the day-to-day activities of our management offices. Each regional
office is staffed with leasing, property management, building engineering,
construction, accounting and information systems specialists. By maintaining a
regionally focused organizational structure headed by seasoned managers, we are
able to quickly respond to our tenants' needs and market opportunities.

We currently lease approximately 70% of our properties using our in-house
staff. We employ outside brokers who are monitored by our leasing managers for
the remainder of our properties. We believe that our in-house leasing program
will continue to generate cost savings and revenue increases by reducing
third-party leasing commissions and allowing us to closely monitor our asking
rents and leasing terms.

3
4

All of our management and regional offices are networked with our corporate
office and have access to the Internet and our e-mail, accounting and lease
management systems. Our accounting and lease management systems employ the
latest technology and allow both corporate and field personnel access to tenant
and prospective tenant-related information to enhance responsiveness and
communication of marketing and leasing activity for each property.

Business Strategies

Our primary business strategy is to actively manage our portfolio to
achieve gains in occupancy and rental rates, to maximize income from ancillary
operations and services and to reduce operating expenses. When market conditions
permit, we may also develop or acquire properties in submarkets where we can use
our local market expertise and extensive real estate experience.

Through our corporate office and regional offices, we implement our
business strategies by:

- using integrated decision making to provide pro-active solutions to the
space needs of users in the markets where we have extensive real estate
and technical expertise;

- emphasizing quality service, tenant satisfaction and retention;

- employing intensive property marketing and leasing programs; and

- implementing cost control management techniques and systems that
capitalize on economies of scale and concentration arising from the size
and geographic focus of our portfolio.

We believe the implementation of these operating practices has been
instrumental in the increased occupancy and improved operating results of our
existing portfolio.

Integrated Decision Making

Our management, leasing, development, renovation, acquisition and finance
teams coordinate their activities to enhance responsiveness to market
opportunities and to provide pro-active solutions to the space needs of users in
the submarkets where we have extensive real estate and technical expertise. This
integrated approach permits us to analyze the specific requirements of existing
and prospective tenants and the economic terms and costs for each transaction on
a timely and efficient basis. We are therefore able to commit to leasing,
development or acquisition terms quickly, which facilitates an efficient
completion of tenant space build-out, minimal downtime after lease expirations
and the timely completion of development and acquisition transactions.

Quality Service and Tenant Satisfaction

We strive to provide quality service through our multidisciplinary
operating approach resulting in timely responses to our tenants' needs. Our
seasoned on-site teams interact and resolve most issues relating to tenant
satisfaction and day-to-day operations. For portfolio-wide operational and
administrative functions, our corporate office provides support to all regional
offices and provides immediate response for critical operational issues. This
customer service approach has contributed to an average tenant retention rate of
approximately 75% since our formation.

Aggressive Leasing

The concentration of many of our properties within particular office
submarkets and our relationships with a broad array of tenants and brokers
enable us to pursue aggressive leasing strategies, to effectively monitor the
office space requirements of existing and prospective tenants and to offer
tenants a variety of space alternatives across our portfolio. In 1999, we signed
approximately 990 leases for approximately 4 million net rentable square feet,
including approximately 716,000 square feet of net absorption.

Cost Control and Operating Efficiencies

The size and geographic focus of our portfolio permits us to enhance
portfolio value by lowering operating costs. We seek to capitalize on the
economies of scale and concentration which result from the geographic focus of
our portfolio, the ownership and management of multiple properties within
particular submarkets and the maintenance of a centralized purchasing and
accounting system for cost control at each of our properties.

Growth Strategies

Based on our geographic focus in Southern California and our evaluation of
local market conditions, we believe the following key factors provide us with
opportunities to maximize returns:

- the continued strength of the Southern California economy, particularly
in the submarkets where our properties are located; and

- the limited construction of new office properties in the Southern
California region due to substantial building construction limitations
and a minimum of developable land in many key submarkets.

Internal Growth

We believe that opportunities exist to increase cash flow from our existing
portfolio and that these opportunities will be enhanced as the Southern
California commercial real estate market continues to improve. We achieve
internal growth by:

- maintaining or improving current occupancy throughout our portfolio by
active management and aggressive leasing;

- leasing space and renewing leases as they expire at increasing rents due
to the increased demand for commercial office space in Southern
California;

- controlling operating expenses through active cost control management and
systems;

- realizing economies of scale and concentration due to the size and
geographic focus of our portfolio; and

- sourcing new and innovative revenue streams while providing high quality
services to our tenants.

Maintaining or Improving Current Occupancy

We believe that we have been successful in attracting, expanding and
retaining a diverse tenant base by actively managing our properties with an
emphasis on tenant satisfaction and retention. Our in-house leasing teams,
working with outside leasing brokers, continuously monitor each market to
identify strong prospective tenants who are in need of new or additional space.
We also strive to be responsive to the needs of existing tenants through our
on-site professional management staff and by providing them with alternative
space within our portfolio to accommodate their changing space requirements. Our
success in maintaining and improving occupancy rates is demonstrated, in part,
by the number of existing tenants that have renewed or re-leased their space,
leased additional space to support their expansion need, or moved to other space
within our portfolio.

Leasing Space and Renewing Leases as they Expire at Increasing Rents

We believe that as the commercial real estate market in Southern California
continues to gain strength, there will be a continued increase in demand for
office space and a decline in vacancy rates, which are expected to result over
time in increasing market rents. We believe we will have significant
opportunities to increase cash flow during periods of increasing market rents by
renewing or re-leasing space as leases expire at higher rents.

6

Cost Control Management and Systems

We plan to continue lowering our operating expenses through active cost
control management at all of our properties. We focus on cost control in various
areas of our operations. We continuously monitor the operating performance of
our properties and employ energy-enhancing and expense recovery technologies
when appropriate. These system enhancements include:

- lighting retrofits;

- replacement of inefficient heating, ventilation and air conditioning
systems;

- computer-driven energy management systems that monitor and react to the
climatic requirements of individual properties;

- automated security systems that allow us to provide security services to
our tenants at a lower cost;

- enhancement of billing systems, which enable us to more efficiently
recover operating expenses from our tenants; and

- on-going preventive maintenance programs to operate our building systems
efficiently, thereby reducing operating costs.

Capitalizing on Economies of Scale and Concentration

In order to capitalize on economies of scale and concentration arising from
the size and geographic focus of our portfolio, our property managers and
building engineers are often responsible for several properties, which spreads
administrative and maintenance costs over those properties and reduces per
square foot expenses. In addition, we believe that parking operations building
services and supplies contracted or purchased in bulk on a portfolio-wide basis
will facilitate further benefits from these economies of scale and
concentration.

Sourcing Additional Revenue while Providing High Quality Services to Tenants

By implementing the next generation of technology in our properties, we
believe we will be able to further increase occupancy, tenant retention and
rents in the future. In 1998, we entered into an agreement with a national
technology/access management firm that has successfully marketed our rooftop
space to telecommunications providers as antennae sites resulting in additional
revenue and providing additional voice and data technology options to our
tenants. During 1999, we completed an agreement with a premium broadband
internet access and applications services provider to deploy its
building-centric, fiber optic network in a majority of our portfolio. In
addition to high speed Internet services, this network will provide our tenants
with a wide range of next generation business applications and e-commerce tools,
including video and audio conferencing, e-mail and unified messaging.

External Growth

We believe in the strength and potential of the Southern California
commercial real estate market, and we intend to continue to focus our resources
in this region. We have assembled a management team that has extensive
experience and knowledge in this market that we believe provides us with a
competitive advantage in identifying and capitalizing on development, renovation
and acquisition opportunities.

Subject to capital availability and market conditions, our approach is to
seek development, renovation and acquisition opportunities in Southern
California submarkets where we have an existing presence and where the following
conditions exist:

- low vacancy rates;

- opportunities for rising rents due to employment growth and population
movements;

- a minimal amount of developable land; and

6
7

- significant barriers to entry because of constraints on new development,
including challenging entitlement processes, strictly enforced height and
density restrictions and governmental requirements resulting in
significant additional construction costs.

Employees

As of December 31, 1999, we had approximately 280 full-time employees that
perform all of our property management, accounting, finance and acquisition
activities and a majority of our leasing transactions.

(D) FOREIGN OPERATIONS

We do not engage in any foreign operations or derive any revenue from
foreign sources.

ITEM 2. PROPERTIES

Existing Portfolio

As of December 31, 1999, our portfolio consisted of 142 primarily office
properties, containing approximately 18.5 million net rentable square feet, that
individually range from approximately 12,000 - 600,000 net rentable square feet.
Our portfolio consists of primarily suburban office properties located in Los
Angeles, Orange, San Diego, Ventura, Riverside, San Bernardino and Kern
Counties. We believe that our properties are located within desirable and
established business communities and are well maintained. Our properties offer
an array of amenities including security, parking, conference facilities,
on-site management, food services and health clubs.

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.

(2) Excludes 48 properties and 4,722,281 net rentable square feet under triple
net and modified gross leases.

Development Properties

In addition to the properties listed above, we currently have three
properties under development containing approximately 700,000 net rentable
square feet. We estimate the total costs of developing these three properties
will be approximately $177.7 million of which $34.3 million had been incurred as
of December 31, 1999. Total estimated costs include purchase and closing costs
and anticipated construction costs, tenant improvements, leasing commissions and
carrying costs during development. One of the properties, 6060 Center Drive, is
an approximately 241,000 net rentable square foot multi-tenant office building.
The second property is an approximately 159,000 square foot build-to-suit office
building being developed for Univision Communications, Inc. The third property,
6080 Center Drive, is an approximately 300,000 net rentable square foot
multi-tenant building.

These properties are located in the Howard Hughes Center, a 70-acre
commercial development located two miles north of Los Angeles International
Airport, immediately adjacent to the San Diego Freeway (I-405), with on- and
off-ramps that directly serve the site. We have entitlements to construct
approximately 600,000 net rentable square feet of additional office space at the
Howard Hughes Center.

office space at the Howard Hughes Center, including the 6080 Center Drive
property described above.

(5) In December 1999, we signed an agreement with Univision Communications, Inc.
for development of an approximately 159,000 net rentable square foot
build-to-suit office building at the Howard Hughes Center scheduled to be
completed in the third quarter of 2001.

Acquisitions

We acquired four properties totaling approximately 524,000 net rentable
square feet during 1999 for a total cost of approximately $89.8 million.

Tenant Information

As of December 31, 1999, we had over 3,000 tenants, with no one tenant
representing more than 2.0% of the aggregate annualized base rent of our
properties, and only three tenants individually representing more than 1.0% of
our aggregate annualized base rent. Our properties are leased to local, national
and foreign companies engaged in a variety of businesses including financial
services, entertainment, health care services, accounting, law, computer
technology, education and publishing.

Our leases are typically structured for terms of three, five or ten years.
Leases typically contain provisions permitting tenants to renew expiring leases
at prevailing market rates. A majority of our leases are full service gross
leases under which tenants typically pay for all real property taxes and
operating expenses above those for an established base year or expense stop.
Tenants generally pay directly, without regard to a base year or expense stop,
for overtime use of heating and air conditioning and for on-site monthly
employee and visitor parking. We are generally responsible for structural
repairs.

The following table presents information as of December 31, 1999 derived
from the twenty largest tenants at our properties, based on the percentage of
aggregate portfolio annualized base rent:

ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS

Our common stock began trading on the New York Stock Exchange, or NYSE, on
October 4, 1996 under the symbol "ARI." On March 17, 2000, the last reported
sales price per share of common stock on the NYSE was $20 15/16, and there were
approximately 185 registered holders of record of our common stock. The table
below sets forth the quarterly high and low closing sales price per share of
common stock reported on the NYSE and the distributions per share we declared
with respect to each period.

1998
First Quarter.............................. 30 7/8 27 1/2 0.42
Second Quarter............................. 28 13/16 25 3/16 0.42

Third Quarter.............................. 23 1/4 20 3/8 0.445
Fourth Quarter........................... 21 1/8 17 3/8 0.445


We pay quarterly distributions to common stockholders at the discretion of
our Board of Directors. Distribution amounts depend on our funds from
operations, financial condition and capital requirements, annual distribution
requirements under the REIT provisions of the Internal Revenue Code and such
other factors as the Board of Directors deems relevant.

Pursuant to the recommendations of our Board of Directors, a Merger
Committee of the Board of Directors comprised of three non-employee directors
and outside legal counsel, on April 28, 1999, we acquired Namiz, Inc. in a
tax-free, stock-for-stock merger in which we issued 775,196 shares of our common
stock to Namiz's stockholders. Prior to the acquisition, Namiz was wholly owned
by Richard S. Ziman, our Chairman of the Board and Chief Executive Officer, and
Victor J. Coleman, our President and Chief Operating Officer. At the time of the
acquisition, Namiz's sole assets were common OP Units of the Operating
Partnership. In the merger, each share of Namiz common stock then issued and
outstanding was converted into approximately 775.2 shares of our common stock,
with the exchange ratio calculated by dividing 775,196 (the number of common OP
Units owned by Namiz) by 1,000 (the number of shares of Namiz common stock
issued and outstanding immediately prior to the merger). As a result, Namiz's
stockholders converted their proportionate interest in the common OP Units held
by Namiz into an economically equivalent number of shares of our common stock.
The shares of our common stock were issued to Namiz's stockholders in reliance
upon an exemption from registration provided by Section 4(2) under the
Securities Act as a transaction by an issuer not involving a public offering.

On September 7, 1999, the Operating Partnership completed a $50 million
private placement of 8 5/8% Series B Cumulative Redeemable Preferred Operating
Partnership Units to an institutional investor. These Preferred OP Units are
callable by the Operating Partnership after five years and are exchangeable by
the holder after ten years into our 8 5/8% Series B Cumulative Redeemable
Preferred Stock, on a one-for-one basis. The Preferred OP Units have no stated
maturity or mandatory redemption and are subordinate to all debt. We used the
net proceeds from this private placement to repay a portion of our lines of
credit. The Preferred OP Units were issued in reliance upon an exemption from
registration provided by Section 4(2) under the Securities Act as a transaction
by an issuer not involving a public offering.

(1) We consider funds from operations, as defined by the National Association of
Real Estate Investment Trusts, or NAREIT, to be a useful financial measure
of our operating performance. We believe that funds from operations provides
investors with an additional basis to evaluate our ability to service debt
and to fund acquisitions and other capital expenditures. Funds from
operations should not be considered an alternative to net income determined
in accordance with generally accepted accounting principles, or GAAP, as an
indicator of our financial performance or as a substitute for cash flow from
operating activities determined in accordance with GAAP as a measure of our
liquidity. Funds from operations also is not necessarily indicative of funds
available to fund our cash needs, including our ability to make
distributions or to service our debt.

23

The White Paper on funds from operations approved by the Board of Governors
of NAREIT in October 1999 defines funds from operations as net income or
loss computed in accordance with GAAP, excluding gains or losses from
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 compute funds from operations in accordance with standards
established by the White Paper which may differ from the standards used by
other REITs and, accordingly, our funds from operations may not be
comparable to other REITs.

(2) As used in this Form 10-K, earnings before interest, taxes, depreciation and
amortization, or EBITDA, means revenue less property operating expenses and
general and administrative expenses. EBITDA does not represent cash
generated from operating activities in accordance with GAAP and should not
be considered as an alternative to operating income or net income as an
indicator of performance or as a substitute for cash flow from operating
activities determined in accordance with GAAP as a measure of our liquidity.
We have included information with respect to EBITDA because we understand
that this information may be used as one measure of operating performance.

(3) Fixed charges consist of interest costs, whether expensed or capitalized,
amortization of deferred financing costs, amortization of discounts or
premiums related to indebtedness and preferred unit distributions.

(4) The ratios of earnings to fixed charges were computed by dividing earnings
by fixed charges. For this purpose, earnings have been calculated by adding
fixed charges, excluding capitalized interest and preferred unit
distributions, to income or loss before extraordinary items.

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

Overview

The following discussion should be read in conjunction with Item 6,
Selected Financial Data, and our historical consolidated financial statements
and related notes thereto included elsewhere in this Form 10-K.

We are a self-administered and self-managed real estate investment trust
that owns, manages, leases, develops, renovates and acquires commercial
properties located in Southern California. We are a full-service real estate
organization managed by 11 senior executive officers who have an average of 16
years of experience in the real estate industry. We perform all property
management, accounting, finance and acquisition activities and a majority of our
leasing transactions with our own staff of approximately 280 employees.

We are Southern California's largest publicly traded office landlord as
measured by total net rentable square feet owned, as of December 31, 1999. Since
our formation in 1996, we have acquired 118 properties containing approximately
14.5 million net rentable square feet for a total purchase price of
approximately $1.9 billion. As of December 31, 1999, our portfolio consisted of
142 primarily office properties containing approximately 18.5 million net
rentable square feet and three properties with approximately 700,000 net
rentable square feet under development. As of December 31, 1999, our properties
were approximately 95.1% leased, excluding three existing properties under
renovation.

Our primary business strategy is to actively manage our portfolio to
achieve gains in occupancy and rental rates, maximize income from ancillary
operations and services and to reduce operating expenses. When market conditions
permit, we may also develop or acquire new properties in submarkets where we can
use our local market expertise and extensive real estate experience.

Results Of Operations

Our financial position and operating results are primarily comprised of our
portfolio of commercial properties and income derived from those properties.
Therefore, financial data from period to period is affected by the timing of
significant property acquisitions.

The increase in revenue from rental operations and property expenses in
1999 is primarily from properties acquired during 1998 and 1999. The 1998
amounts do not include a full year of operations for the 66 properties we
acquired during 1998 or for the four properties we acquired during 1999.

(1) See analysis of Properties Owned for all of 1998 and 1999.

Interest and other income decreased by approximately $700,000 in 1999 as
compared to 1998, primarily due to lower interest income earned on amortizing
mortgage notes receivable acquired in September 1997.

General and administrative expenses were approximately $7.4 million, or
2.2% of total revenue, in 1999 as compared to $6.7 million, or 2.3% of total
revenue, in 1998. General and administrative expenses as a percentage of total
revenue decreased in 1999 compared to 1998 primarily due to benefits achieved
from economies of scale and concentration over a larger property portfolio.

Interest expense increased approximately $16.8 million in 1999 as compared
to 1998. This increase was due to higher outstanding debt balances in 1999
primarily to fund property acquisitions and tenant improvement build-outs, which
was partially offset by slightly lower effective interest rates in 1999.

Depreciation and amortization expense increased by approximately $18.0
million in 1999, primarily due to the 70 properties we acquired in 1998 and
1999.

(1) Excludes straight-line rent adjustments.

Revenue from rental operations for the 72 properties we owned for all of
1999 and 1998 computed on a GAAP basis increased by approximately $17.3 million
in 1999 compared to 1998. This increase was primarily due to increases in rental
rates and a four percentage point increase in average occupancy in 1999 for this
pool of properties representing approximately 10.3 million net rentable square
feet. This increase in occupancy not only contributed to higher rental revenue
but also resulted in higher tenant expense reimbursements, parking income and
miscellaneous tenant charges. Miscellaneous tenant charges include revenue from
after-hour utility billings, signage, satellite income and lease termination
settlements. Lease termination settlements totaled approximately $9.7 million in
1999 compared to $4.1 million in 1998 for these properties.

Excluding only the straight-line rent adjustments for these properties,
revenue from rental operations, computed on a cash basis, increased by
approximately $18.2 million for the reasons described above.

Property operating expenses for these properties increased by approximately
$4.9 million in 1999 compared to 1998, primarily due to higher repairs,
maintenance and marketing and overhead expenses. These increases were primarily
related to the four percentage point increase in average occupancy in 1999.

(1) See analysis of Properties Owned for all of 1997 and 1998.

Interest and other income increased by approximately $1.9 million in 1998
as compared to 1997, primarily due to higher interest income earned on mortgage
notes receivable acquired in September 1997 and on cash deposits required by
some of our mortgage loans.

General and administrative expenses were approximately $6.7 million, or
2.3% of total revenue, in 1998 as compared to $4.3 million, or 3.2% of total
revenue, in 1997. General and administrative expenses as a percentage of total
revenue decreased in 1998 compared to 1997 primarily due to benefits achieved
from economies of scale and concentration over a larger property portfolio.

Interest expense increased approximately $23.9 million in 1998 as compared
to 1997. This increase was due to higher outstanding debt balances in 1998
primarily to fund property acquisitions, which was partially offset by slightly
lower effective interest rates in 1998.

In September 1997, we recorded a loss of approximately $3.1 million related
to the retirement of agreements to convert some floating rate debt liabilities
to fixed rate liabilities. The underlying variable rate liabilities were repaid
in full with proceeds from an equity offering in July 1997.

Depreciation and amortization expense increased by approximately $31.6
million in 1998, primarily due to the 104 properties we acquired in 1997 and
1998.

(1) Excludes straight-line rent adjustments.

Revenue from rental operations for the 34 properties we owned for all of
1998 and 1997 computed on a GAAP basis increased by approximately $1.1 million
in 1998 compared to 1997. This increase was primarily due to increases in rental
rates, a two percentage point increase in average occupancy in 1998 and higher
miscellaneous tenant charges for this pool of properties representing
approximately 5.4 million net rentable square feet. Miscellaneous tenant charges
include revenue from after-hour utility billings, signage, satellite income and
lease termination settlements. Lease termination settlements totaled
approximately $2.0 million in 1998 compared to $316,000 in 1997 for these
properties. These increases were partially offset by lower tenant expense
reimbursements in 1998, primarily due to resetting base years for leases that
were retenanted in 1998 and the reversing effect of straight-line rent
adjustments on specific properties in 1998.

Excluding only the straight-line rent adjustments for these properties,
revenue from rental operations, computed on a cash basis, increased by
approximately $1.9 million for the reasons described above.

Property operating expenses for these properties decreased by approximately
$1.9 million in 1998 compared to 1997, primarily due to lower repairs,
maintenance and marketing and overhead expenses achieved primarily from
economies of scale and concentration over a larger property portfolio.

LIQUIDITY AND CAPITAL RESOURCES

Cash Flows

Cash provided by operating activities increased by $23.1 million to $155.1
million for the year ended December 31, 1999, as compared to $132.0 million for
the year ended December 31, 1998, primarily due to operating results from the 70
properties acquired in 1998 and 1999.

Cash used in investing activities decreased by $811.2 million to $268.3
million in 1999 compared to $1.1 billion in 1998, primarily due to a reduction
in property acquisitions in 1999.

Cash provided by financing activities decreased by $831.1 million to $115.7
million, as compared to $946.8 million in 1998. This decrease was primarily due
to the timing of equity issuances. During 1998, we had net proceeds of
approximately $706.6 million from equity issuances as compared to $49.0 million
in net proceeds from equity issuances in 1999. Cash provided by financing
activities for the year ended December 31, 1999 consisted primarily of net
proceeds from mortgage loans, unsecured lines of credit and the issuance by the
Operating Partnership of two million 8 5/8% Series B Cumulative Redeemable
Preferred Units, partially offset by distributions to stockholders and minority
interests.

Capital Commitments

As of December 31, 1999, we had approximately $23.6 million outstanding in
capital commitments related to tenant improvements, development, renovation
costs and property-related capital expenditures.

Available Borrowings, Cash Balances And Capital Resources

We have a $300 million unsecured line of credit from a group of banks led
by Wells Fargo. This line of credit bears interest at a rate ranging between
LIBOR plus 1.2% and LIBOR plus 1.45%, depending on our leverage ratio. The
agreement governing this line of credit provides for the rate to be lowered to
between LIBOR plus 0.9% and LIBOR plus 1.15%, depending on our unsecured debt
rating. Under specified circumstances, we have the option to convert the
interest rate to the prime rate plus 0.5%. This line of credit has a commitment
fee ranging from 0.125% to 0.25% on the unused balance. As of December 31, 1999,
the effective interest rate on this line of credit was 7.52%, the aggregate
outstanding balance on this line of credit was $280.9 million, and $19.1 million
was available for additional borrowing. This line of credit matures on June 1,
2000. Proceeds from this line of credit have been used, among other things, to
fund acquisitions, provide funds for tenant improvements, capital expenditures
and provide for working capital.

We also have an unsecured line of credit with a total commitment of $10
million from City National Bank. This line of credit accrues interest at the
City National Bank Prime Rate less 0.875% and is scheduled to mature on August
1, 2000. As of December 31, 1999, the effective interest rate on this line of
credit was 7.625%, there was an outstanding balance of $8.0 million, and $2.0
million was available for additional borrowing. Proceeds from this line of
credit have been used, among other things, to provide funds for tenant
improvements and capital expenditures and provide for working capital and other
purposes.

On January 20, 1999, we increased our prepayable term loan with an
affiliate of Lehman Brothers from $81.4 million to $111.4 million. This loan was
secured by seven of our properties, bore interest at LIBOR plus 2.25% per year
and required monthly payments of interest only. As discussed below, we
refinanced this loan on May 5, 1999.

On April 5, 1999, we closed a $115 million loan with Mass Mutual Life
Insurance Company that is secured by twelve of our properties, has a 10-year
term, bears interest at a fixed rate of 6.94%, requires monthly payments of
principal and interest and is amortized over a 25-year period. Proceeds from
this loan were used to repay $76.4 million of our prepayable term loan with an
affiliate of Lehman Brothers and to repay a portion of our lines of credit.

On April 30, 1999 we closed a $22.5 million loan with an affiliate of
Lehman Brothers that is secured by three of our properties, has a 10-year term,
bears interest at a fixed rate of 7.54%, requires monthly payments of principal
and interest and is amortized over a 30-year period. Proceeds from this loan
were used to repay a portion of our lines of credit.

On May 5, 1999, we refinanced the remaining $35 million outstanding under
our loan with an affiliate of Lehman Brothers with a promissory note for $62.5
million that is secured by three of our properties, bears interest at LIBOR plus
2.25% per year, requires monthly payments of interest only and matures on
November 1, 2000. This loan had an effective interest rate of 8.07% at December
31, 1999. The remaining proceeds from this loan were used to repay a portion of
our lines of credit.

On July 23, 1999, we entered into a construction loan with a total
commitment of $50 million related to our development of the approximately
241,000 net rentable square foot 6060 Center Drive office building in the Howard
Hughes Center. This loan is secured by specific property and construction
improvements, bears interest at LIBOR plus 2.0%, requires monthly payments of
interest only, and matures on December 30, 2000, with two one-year extension
options. If we meet construction completion and leasing benchmarks, the interest
rate on the construction loan may be reduced to LIBOR plus 1.75%, and then to
LIBOR plus 1.5%. As of December 31, 1999, the effective interest rate of this
loan was 8.23%, there was an outstanding principal balance of $22.0 million and
$28.0 million was available for additional borrowing.

On July 27, 1999, we closed a $58 million prepayable term loan with an
affiliate of Lehman Brothers. This loan is secured by six of our properties and
has the same terms as the loan that was increased on May 5, 1999, as described
above. Proceeds from this loan were used to repay a portion of our lines of
credit and to fund specific capital expenditures.

On September 7, 1999, the Operating Partnership completed a $50 million
private placement of two million 8 5/8% Series B Cumulative Redeemable Preferred
Units to an institutional investor. These preferred units are callable by us
after five years and are exchangeable after 10 years by the holder into our
8 5/8% Series B Cumulative Redeemable Preferred Stock on a one-for-one basis.
The preferred units have no stated maturity or mandatory redemption and are
subordinated to all debt. We used the net proceeds from this private placement
to repay a portion of our lines of credit.

On January 25, 2000, we expanded one of our two prepayable term loans with
an affiliate of Lehman Brothers totaling $120.5 million by $25 million,
resulting in a combined outstanding balance of $145.5 million for both loans.
The two loans are secured by nine of our properties, bear interest at LIBOR plus
2.25% per year, require monthly payments of interest only and mature on November
1, 2000. These loans had an effective interest rate of 8.07% at December 31,
1999. Proceeds from this loan expansion were used, among other things, to
provide funds for tenant improvements, capital expenditures and working capital.

(1) Includes amortization of prepaid financing costs.

(2) Based on contractual rates effective at December 31, 1999 that expire
through February 29, 2000. Assuming market LIBOR rates at December 31, 1999,
the unsecured debt and floating rate debt weighted average interest rates
would have been 7.46% and 7.75%, respectively, while the total debt weighted
average interest rate would have been 7.54%.

As of December 31, 1999, we had approximately $25.6 million in cash and
cash equivalents, including $18.5 million in restricted cash, representing $13.7
million in interest-bearing cash deposits required by some of our mortgage loans
payable. In addition, we had $4.8 million in cash impound accounts for real
estate taxes and insurance as required by several of our mortgage loans payable.

As of December 31, 1999, we had $21.1 million available under our lines of
credit.

On March 17, 2000, the Operating Partnership issued $250 million of senior
unsecured notes in two tranches, with $200 million at an interest rate of 8.875%
due in March 2005 and $50 million at an interest rate of 9.150% due in March
2010. These notes will be the Operating Partnership's senior unsecured
obligations and pay interest semi-annually on March 1, and September 1, of each
year. Net proceeds from this offering were used to repay two prepayable term
loans to an affiliate of Lehman Brothers described above totaling $145.5
million, a $5.0 million mortgage loan and approximately $96.1 million under our
unsecured lines of credit. These senior unsecured notes were issued in a private
placement in reliance upon an exemption from registration provided by Section
144(a) under the Securities Act. As part of issuing these notes, the Operating
Partnership has agreed to file a registration statement with the Securities and
Exchange Commission within 90 days after the notes are issued, enabling the
holders of the notes to exchange the privately placed notes for publicly traded
notes with identical terms other than those pertaining to transfer restrictions
and liquidated damages.

We expect to continue meeting our short-term liquidity and capital
requirements generally through our net cash provided by operating activities and
from proceeds from our lines of credit. We believe that the net cash provided by
operating activities will continue to be sufficient to pay any distributions
necessary to enable us to continue qualifying as a REIT. We also believe that
the foregoing sources of capital will be sufficient to fund our short-term
liquidity needs, other than scheduled debt principal repayments, for the
foreseeable future, including recurring non-revenue enhancing capital
expenditures, tenant improvements and leasing commissions.

We expect to meet long-term liquidity and capital requirements, such as
scheduled debt principal repayments, renovation costs, property acquisitions and
other non-recurring capital expenditures, through long-term secured and
unsecured indebtedness and the issuance of additional equity or equity-related
securities.

(1) We consider funds from operations, as defined by NAREIT to be a useful
financial measure of our operating performance. We believe that funds from
operations provides investors with an additional basis to evaluate our
ability to service debt and to fund acquisitions and other capital
expenditures. Funds from operations should not be considered an alternative
to net income determined in accordance with GAAP, as an indicator of our
financial performance, as a substitute for cash flow from operating
activities

32
33

determined in accordance with GAAP or as a measure of our liquidity. Funds
from operations also is not necessarily indicative of funds available to
fund our cash needs, including our ability to service our debt.

The White Paper on funds from operations approved by the Board of Governors
of NAREIT in October 1999 defines funds from operations as net income or
loss computed in accordance with GAAP, excluding gains or losses, from
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 compute funds from operations in accordance with
standards established by the White Paper which may differ from the
standards used by other REITs and, accordingly, our funds from operations
may not be comparable to other REITs.

(2) Excludes $575,000 in distributions made to the former minority partners in
the World Savings office property.

IMPACT OF YEAR 2000

In 1999, we completed our remediation and testing of systems with respect
to the Year 2000 date change. As a result of our planning and implementation
efforts, we experienced no significant disruptions in mission critical
information technology and non-information technology systems and believe those
systems successfully responded to the Year 2000 date change. We incurred costs
of approximately $500,000 during 1999 in connection with remediating our
systems. We are not aware of any material problems resulting from Year 2000
issues, either with our products, our internal systems or the products and
services of third parties. We will continue to monitor our mission critical
computer applications and those of our suppliers and vendors throughout the year
to ensure that any latent Year 2000 matters that may arise are addressed
promptly.

FORWARD-LOOKING STATEMENTS

This Form 10-K, 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, cash available for distribution,
acquisitions, lease renewals, property development, property renovation, capital
requirements and general business, industry and economic conditions applicable
to us. Also, documents we subsequently file with the Securities and Exchange
Commission and incorporated herein by reference will contain forward-looking
statements. Actual results could differ materially from those projected in the
forward-looking statements as a result of the risk factors set forth below and
the matters set forth or incorporated in this Form 10-K generally. We caution
the reader, however, that this list of factors may not be exhaustive,
particularly with respect to future filings.

ITEM 7A. 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
may 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 and legal enforceability of
hedging contracts. We do not enter into any transactions for speculative or
trading purposes.

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 December
31, 1999, a 1% increase in interest rates on our $431.4 million of floating rate
debt would decrease annual future earnings and cash flows by approximately $4.3
million and would not have an impact

33
34

on the fair value of the floating rate debt. A 1% decrease in interest rates on
our $431.4 million of floating rate debt would increase annual future earnings
and cash flows by approximately $4.3 million and would not have an impact on the
fair value of the floating rate debt. A 1% increase or decrease in interest
rates on our secured notes receivable would not have a material impact on annual
future earnings, cash flows and the fair value of the secured notes receivable.

These amounts are determined by considering the impact of the 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.

RISK FACTORS

In addition to the other information contained or incorporated by reference
in this Form 10-K readers should carefully consider the following factors.

REAL ESTATE INVESTMENT RISKS

An Inability To Retain Tenants Or Rent Space Upon Lease Expirations May
Adversely Affect Our Ability To Service Our Debt.

Over the next five years, 2,837 leases comprising 77.4% of our leased net
rentable square footage and 76.4% of our annualized base rents at December 31,
1999, will expire. If we are unable to promptly relet or renew leases for all or
a substantial portion of this space, or if the rent upon renewal or reletting
are significantly lower than expected, our cash flow and the amounts available
for distributions and to pay our debt obligations could be adversely affected.

Our Operating Performance And Property Values Will Be Affected By Changes In
The Economic Climate In Southern California.

All of our properties are located in Southern California. Our revenue and
the value of our properties may be affected by a number of factors, including
the Southern California economic climate and real estate market, which could
adversely affect the amounts available for distributions and to pay our debt
obligations.

Competition Affects Occupancy Levels And Rents Which Could Adversely Affect
Our Revenue.

Many office properties compete with our properties in attracting tenants to
lease space. Some of the competing properties may be newer, better located or
owned by parties better capitalized than we are. The number of competitive
commercial properties in a particular area could have a material adverse effect
on the rents we can charge and our ability to lease space in our existing
properties or at newly acquired or developed properties.

The Financial Condition And Solvency Of Our Tenants May Reduce Our Cash Flow.

Tenants may experience a downturn in their business which may cause them to
miss rental payments when due or to seek the protection of bankruptcy laws,
which could result in rejection and termination of their leases or a delay in
recovering possession of their premises. Although we have not experienced
material losses from tenant bankruptcies, we cannot assure you that tenants will
not file for bankruptcy protection in the future or, if any tenants file, that
they will affirm their leases and continue to make rental payments in a timely
manner.

34
35

Because Real Estate Investments Are Illiquid, We May Not Be Able To Sell
Properties When Appropriate.

Equity real estate investments are relatively illiquid. That illiquidity
will tend to limit our ability to vary our portfolio promptly in response to
changes in economic or other conditions. In addition, the Internal Revenue Code
of 1986, as amended, may under specified circumstances impose a 100% prohibited
transaction tax on the profits derived from our sale of properties held for
fewer than four years, which could affect our ability to sell our properties.

Increases In Taxes And Regulatory Compliance Costs May Reduce Our Revenue.

Except for our triple net leases, tax increases are generally not passed
through to tenants under our leases. Therefore, any tax increases may adversely
affect our cash flow and our ability to pay or refinance our debt obligations.
Our properties are also subject to various federal, California and local
regulatory requirements, such as requirements of the Americans with Disabilities
Act, and California and local fire and life safety requirements. Failure to
comply with these requirements could result in the imposition of fines by
governmental authorities or awards of damages to private litigants. We believe
that our properties are currently in substantial compliance with these
regulatory requirements and that any noncompliance would not have a material
adverse effect on us. We cannot assure you, however, that these requirements
will not be changed or that new requirements will not be imposed that would
require significant unanticipated expenditures by us and could have an adverse
effect on our cash flow and the amounts available for distributions and to pay
our debt obligations.

We May Acquire Properties Through Partnerships Or Joint Ventures With Third
Parties That Could Result In Financial Dependency And Management Conflicts.

Although we currently do not have plans to do so, we may participate with
other entities in property ownership through joint ventures or partnerships in
the future. Partnership or joint venture investments may, under certain
circumstances, involve risks not otherwise present, including:

- our partners or co-venturers might become bankrupt;

- our partners or co-venturers might at any time have economic or other
business interests or goals which are inconsistent with our business
interests or goals; and

- our partners or co-venturers may be in a position to take action contrary
to our instructions or requests contrary to our policies or objectives.

We will, however, seek to maintain sufficient control of any partnerships
or joint ventures with which we may become involved to permit our business
objectives to be achieved.

We May Not Be Able To Integrate Or Finance Our Acquisitions And Renovation
Activities And Our Acquisitions And Renovations May Not Perform As Expected.

As we acquire additional properties, we will be subject to risks associated
with managing new properties, including lease-up and tenant retention. In
addition, our ability to manage our growth effectively will require us to
successfully integrate our new acquisitions into our existing management
structure. We cannot assure you that we will be able to succeed with that
integration or effectively manage additional properties or that newly acquired
properties will perform as expected. Changing market conditions, including
competition from other purchasers of suburban office properties, may diminish
our opportunities for attractive additional acquisitions.

We intend to expand and renovate our properties from time to time.
Expansion and renovation projects generally require expenditures of capital as
well as various government and other approvals, the receipt of which cannot be
assured. While our policies with respect to expansion and renovation activities
are intended to limit some of the risks otherwise associated with these
activities, we will nevertheless incur risks, including expenditures of funds
on, and devotion of our time to, projects that may not be completed.

35
36

We May Not Be Able To Integrate Or Finance Our Development Activities.

We also intend to review, from time to time, opportunities for developing
and constructing office buildings and other commercial properties in accordance
with our development and underwriting policies. Risks associated with our
development and construction activities may include:

- abandonment of development opportunities due to a lack of financing or
other reasons;

- construction costs of a property exceeding original estimates, possibly
making the property uneconomical;

- occupancy rates and rents at a newly completed property may not be
sufficient to make the property profitable;

- construction and lease-up may not be completed on schedule, resulting in
increased debt service expense and construction costs; and

- development activities would also be subject to risks relating to the
inability to obtain, or delays in obtaining, all necessary zoning,
land-use, building, occupancy and other required governmental permits and
authorizations.

We May Not Be Able To Expand Into New Markets Successfully.

While we have generally limited our business primarily to the Southern
California market, it is possible that we will in the future expand our business
to new geographic markets. We will not initially possess the same level of
familiarity with new markets outside of Southern California, which could
adversely affect our ability to manage, lease, develop or acquire properties in
new localities.

FINANCING RISKS

Our Significant Amount Of Debt Could Limit Our Operational Flexibility Or
Otherwise Adversely Affect Our Financial Condition.

We have a significant amount of debt. As of December 31, 1999, we had total
debt of approximately $1.0 billion, consisting of approximately $741 million in
secured debt and approximately $289 million of unsecured debt. See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."

Our substantial indebtedness could:

- require us to dedicate a substantial portion of our cash flow to pay our
debt, thereby reducing the availability of our cash flow to fund
distributions, working capital, capital expenditures, acquisition and
development activity and other business purposes;

- make it more difficult for us to satisfy our debt obligations;

- limit our ability to refinance our debt and obtain additional debt
financing; and

- increase our vulnerability to general adverse economic and real estate
industry conditions and limit our flexibility in planning for, or
reacting to, changes in our business and the real estate industry.

We May Be Able To Incur Substantially More Debt Which Would Increase The Risks
Associated With Our Substantial Leverage.

Despite current indebtedness levels, we may still be able to incur
substantially more debt in the future. We may borrow up to a maximum of $310
million under our existing lines of credit. If new debt is added to our current
debt levels, the related risks could intensify and could increase the risk of
default on our indebtedness.

36
37

Scheduled Debt Payments And Rising Interest Rates Could Adversely Affect Our
Financial Condition.

We are subject to risks normally associated with debt financing. Cash flow
could be insufficient to meet required payments of principal and interest. We
may not be able to refinance existing indebtedness, which in virtually all cases
requires substantial principal payments at maturity, and, if we can, the terms
of the refinancing might not be as favorable as the terms of our existing
indebtedness. If principal payments due at maturity cannot be refinanced,
extended or paid with proceeds of other capital transactions, such as new equity
capital, our cash flow will not be sufficient in all years to repay all maturing
debt. In addition, at December 31, 1999, approximately 41.9% of our debt was
variable rate debt. If prevailing interest rates or other factors result in
higher interest rates, the increased interest expense would adversely affect our
cash flow and the amounts available to pay distributions and service our debt.
As a protection against rising interest rates, we may enter into agreements such
as interest rate swaps, caps, floors and other interest rate exchange contracts.
These agreements, however, increase our risks as to the other parties to the
agreements not performing or that the agreements could be unenforceable.

Many Of Our Properties Are Subject To Mortgage Financing Which Could Result In
Foreclosure If We Are Unable To Pay Or Refinance The Mortgages When Due.

We currently have outstanding five mortgage financings totaling $558.7
million that are secured by 67 of our properties. The properties in each of
these financings are fully cross-collateralized and cross-defaulted. To the
extent mortgages are cross-collateralized, lenders may seek to foreclose upon
properties that are not the primary collateral for their loans, which may, in
turn, result in acceleration of other debt secured by the properties. Six
additional properties are subject to single property mortgages. If we are unable
to meet our obligations under these mortgages, the properties subject to the
mortgages could be foreclosed upon, which would have a material adverse effect
on us and our ability to pay distributions and service our debt obligations.

TAX RISKS

Our Desire To Qualify As A REIT Restricts Our Ability To Accumulate Cash That
Might Be Used In Future Periods To Make Debt Payments Or To Fund Future
Growth.

In order to qualify as a REIT and avoid federal income tax liability, we
must distribute to our stockholders at least 95% of our net taxable income,
excluding net capital gain, and to avoid income taxation, our distributions must
not be less than 100% of our net taxable income, including capital gains. To
avoid excise tax liability, our distributions to our shareholders for the year
must exceed the sum of 85% of its ordinary income, 95% of its capital gain net
income, and any undistributed taxable income from prior years. As a result of
these distribution requirements, we do not expect to accumulate significant
amounts of cash. Accordingly, these distributions could significantly reduce the
cash available to us in subsequent periods to make payments on our debt
obligations and to fund future growth.

Our Operating Partnership Intends To Qualify As A Partnership, But We Cannot
Guarantee That It Will Qualify.

Our Operating Partnership intends to qualify as a partnership for federal
income tax purposes. However, if the Operating Partnership were a "publicly
traded partnership," it would be treated as a corporation instead of a
partnership for federal income tax purposes unless at least 90% of its income is
qualifying income as defined in the Internal Revenue Code. The income
requirements applicable to REITs and the definition of "qualifying income" for
purposes of this 90% test are similar in most respects. Qualifying income for
the 90% test generally includes passive income, such as specified types of real
property rents, dividends and interest. We believe that the Operating
Partnership would meet this 90% test, but we cannot guarantee that it would. If
the Operating Partnership were to be taxed as a corporation, it would incur
substantial tax liabilities and we would fail to qualify as a REIT for federal
income tax purposes.

37
38

We May Suffer Adverse Tax Consequences And Be Unable To Attract Capital If We
Fail To Qualify As A REIT.

We believe that since our taxable year ended December 31, 1996, we have
been organized and operated, and intend to continue to operate, so as to qualify
for taxation as a REIT under the Internal Revenue Code. Although we believe that
we have been and will continue to be organized and have operated and will
continue to operate so as to qualify for taxation as a REIT, we cannot assure
you that we have been or will continue to be organized or operated in a manner
so as to qualify or remain so qualified. For us to qualify as a REIT, we must
satisfy numerous requirements established under highly technical and complex
Internal Revenue Code provisions for which there are only limited judicial and
administrative interpretations and tests regarding various factual matters and
circumstances not entirely within Arden Realty's control. The complexity of
these provisions and of the applicable Treasury Regulations that have been
promulgated under the Internal Revenue Code is greater in the case of a REIT,
like us, that hold our assets through an investment in a partnership. No
assurance can be given that legislation, new regulations, administrative
interpretations or court decisions will not significantly change the tax laws
with respect to qualification as a REIT or the federal income tax consequences
of qualification. We are, however, not aware of any pending legislation that
would adversely affect our ability to operate as a REIT. Our qualification and
taxation as a REIT depends on our ability to meet, through actual annual
operating results, asset diversification, distribution levels and diversity of
stock ownership, the various qualification tests imposed under the Internal
Revenue Code, the results of which have not been and will not be reviewed by our
tax counsel.

If we failed to qualify as a REIT in any taxable year, we would be subject
to federal income tax, including any applicable alternative minimum tax, on our
taxable income at regular corporate rates. Moreover, unless entitled to relief
under specific statutory provisions, we also would be disqualified as a REIT for
the four taxable years following the year during which qualification was lost.
If we were disqualified as a REIT, our ability to raise additional capital could
be significantly impaired. This could reduce the funds we would have available
to pay distributions to our stockholders and to service our debt.

Even if we qualify for and maintain our REIT status, we will be subject to
certain federal, state and local taxes on our income and property. For example,
if we have net income from a prohibited transaction, specifically sales or other
taxable dispositions of property held primarily for sale to customers in the
ordinary course of business, that income will be subject to a 100% tax.

OTHER RISKS

We Are Subject To Agreements And Policies That May Deter Change In Control
Offers That Might Be Attractive To Our Stockholders.

Certain provisions of our charter and bylaws as well as our stockholder
rights plan, which is described below, may delay, defer or prevent a third party
from making offers to acquire us or control over us. For example, such
provisions may:

Deter tender offers for our common stock, which offers may be attractive to
the stockholders.

Deter purchases of large blocks of common stock, thereby limiting the
opportunity for stockholders to receive a premium for their common stock over
then-prevailing market prices.

Our charter contains a provision designed to prevent a concentration of
ownership among our stockholders that would cause us to fail to qualify as a
REIT. Under the Internal Revenue Code, not more than 50% in value of our
outstanding shares of common stock may be owned, actually or constructively, by
five or fewer individuals, including specific kinds of entities, at any time
during the last half of our taxable year. In addition, if we, or an owner of 10%
or more of our Stock, actually or constructively owns 10% or more of a tenant of
ours, or a tenant of any partnership in which we are a partner, the rent
received by us from that tenant will not be qualifying income for purposes of
the REIT gross income tests. In order to protect us against the risk of losing
REIT status, the ownership limit included in our charter limits actual or
constructive ownership of our outstanding shares of common stock by any single
stockholder to 9.0%, by value or by number of shares, whichever is more
restrictive, of the then outstanding shares of common stock. Actual or
constructive

38
39

ownership of shares of common stock in excess of the ownership limit will cause
the violative transfer or ownership to be void with respect to the transferee or
owner as to that number of shares in excess of the ownership limit and such
shares will be automatically transferred to a trust for the exclusive benefit of
one or more qualified charitable organizations. That transferee or owner will
have no right to vote such shares or be entitled to dividends or other
distributions with respect to such shares.

Although our Board of Directors presently has no intention of doing so,
except as described below, our Board of Directors could waive this restriction
with respect to a particular stockholder if it were satisfied, based upon the
advice of counsel or a ruling from the Internal Revenue Service, that ownership
by such stockholder in excess of the ownership limit would not jeopardize our
status as a REIT and our Board of Directors otherwise decided such action would
be in our best interests. Our Board of Directors has waived our ownership limit
with respect to Mr. Ziman and certain family members and affiliates and has
permitted these parties to actually and constructively own up to 13.0% of the
outstanding shares of common stock.

Our charter authorizes our Board of Directors to cause us to issue
authorized but unissued shares of common stock or preferred stock and to
reclassify any unissued shares of common stock or classify any unissued and
reclassify any previously classified but unissued shares of preferred stock and,
with respect to the preferred stock, to set the preferences, rights and other
terms of such classified or unclassified shares. Although our Board of Directors
has no such intention at the present time, it could establish a series of
preferred stock that could, depending on the terms of such series, delay, defer
or prevent a transaction or a change in control that might involve a premium
price for the common stock or otherwise be in the best interest of our
stockholders.

Our Board of Directors is divided into three classes of directors.
Directors of each class are chosen for three-year terms upon the expiration of
their current terms and each year one class of directors will be elected by the
stockholders. The staggered terms of directors may reduce the possibility of a
tender offer or an attempt to change control even though a tender offer or
change in control might be in the best interest of our stockholders.

In August 1998, we declared a dividend distribution of one preferred share
purchase right on each outstanding share of our common stock. Subject to limited
exceptions, these rights will be exercisable if a person or group acquires 15%
or more of our common stock or announces a tender offer for 15% or more of our
common stock. Under certain circumstances, each right will entitle stockholders
to buy one one-hundredth of a share of our newly created Class A Junior
Participating Preferred Stock at an exercise price of $75. Our Board of
Directors will be entitled to redeem the rights at $.01 per right at any time
before a person has acquired 15% or more of the outstanding common stock. The
Rights Plan will expire in August 2008.

Each right entitles its holder to purchase, at the right's then-current
exercise price, a number of our common shares having a market value at that time
of twice the right's exercise price. Rights held by the person or group seeking
to acquire 15% or more of our common stock will become void and will not be
exercisable to purchase shares at the bargain purchase price. If we are acquired
in a merger or other business combination transaction which has not been
approved by our Board of Directors, each right will entitle its holder to
purchase, at the right's then-current exercise price, a number of the acquiring
company's common shares having a market value at that time of twice the right's
exercise price.

We May Change Policies Without Stockholder Approval.

Our investment, financing, borrowing and distribution policies and our
policies with respect to all other activities, including growth, debt,
capitalization and operations, will be determined by our management. Although we
have no present intention to do so, these policies could be amended or revised
at any time and from time to time at the discretion of our management and Board
of Directors without a vote of our stockholders. In addition, we may change
policies with respect to conflicts of interest provided that the changes are
consistent with applicable legal requirements. A change in these policies could
adversely affect our financial condition, results of operations and market price
of our common stock.

39
40

Losses In Excess Of Our Insurance Coverage Or Uninsured Losses Could Adversely
Affect Our Cash Flow.

We carry comprehensive liability, fire, extended coverage and rental loss
insurance policies which currently cover all of our properties with
specifications and insured limits that we believe are adequate and appropriate
under the circumstances. Some losses, however, are generally not insured against
because it is not economically feasible to do so. Should an uninsured loss or a
loss in excess of insured limits occur, we could lose our capital invested in
the property, as well as the anticipated future revenue from the property and,
in the case of debt which is recourse to us, we would remain obligated for any
mortgage debt or other financial obligations related to the property. Any loss
would adversely affect our cash flow with respect to the property subject to the
loss. Moreover, we would generally be liable for any unsatisfied obligations
other than non-recourse obligations with respect to the property subject to the
loss. We cannot assure you that material losses in excess of insurance proceeds
will not occur in the future.

An Earthquake Could Adversely Affect Our Business.

Southern California is in a high risk geographical area for earthquakes.
Depending upon its magnitude, an earthquake could severely damage our properties
which would adversely affect our business. We maintain earthquake insurance for
our properties and the resulting business interruption. We cannot assure you
that our insurance will be sufficient if there is a major earthquake.

Our Properties May Be Subject To Environmental Liabilities.

Under federal, state and local environmental laws, ordinances and
regulations, a current or previous owner or operator of real estate may be
required to investigate and clean up hazardous or toxic substances or petroleum
product releases at the property and may be held liable to a governmental entity
or to third parties for property damage and for investigation and clean-up costs
in connection with the contamination. These laws typically impose clean-up
responsibility and liability without regard to whether the owner knew of or
caused the presence of the contaminants, and the liability under these laws has
been interpreted to be joint and several unless the harm is divisible and there
is a reasonable basis for allocation of responsibility. These costs may be
substantial, and the presence of these substances, or the failure to remediate
the contamination on the property, may adversely affect the owner's ability to
sell or rent the property or to borrow against the property. Persons who arrange
for the disposal or treatment of hazardous or toxic substances at a disposal or
treatment facility also may be liable for the costs of removal or remediation of
a release of hazardous or toxic substances at the disposal or treatment
facility, whether or not the facility is owned or operated by that person. Some
laws create a lien on the contaminated site in favor of the government for
damages and costs incurred in connection with the contamination. Finally, third
parties may have claims against the owner of the site based on damages and costs
resulting from environmental contamination emanating from that site.

Specific federal, state and local laws, regulations and ordinances govern
the removal, encapsulation or disturbance of asbestos-containing materials when
those materials are in poor condition or in the event of construction,
remodeling, renovation or demolition of a building. These laws may impose
liability for release of asbestos-containing material and may provide for third
parties to seek recovery from owners or operators of real properties for
personal injury associated with asbestos-containing materials. In connection
with the ownership and operation of our properties, we may be potentially liable
for those costs. Except for two properties, one of which is currently undergoing
abatement activities, we are not aware of any friable asbestos-containing
materials at any of our properties.

In the past few years, independent environmental consultants have conducted
or updated Phase I environmental assessments and other environmental
investigations as appropriate at our properties. These environmental site
assessments have included, among other things, a visual inspection of the
properties and the surrounding area and a review of relevant federal, state and
historical documents. Soil and groundwater samplings were performed where
warranted and remediation, if necessary, has or is being conducted.

The environmental site assessments of our properties identified several
properties that may be impacted by known or suspected regional contamination.
The environmental site assessments have not, however, revealed any environmental
liability that we believe would have a material adverse effect on our business,
40
41

assets or results of operations taken as a whole, nor are we aware of any
material environmental liability. Nevertheless, it is possible that our
environmental site assessments do not reveal all environmental liabilities or
that there are material environmental liabilities of which we are unaware.
Moreover, we cannot assure you that future laws, ordinances or regulations will
not impose any material environmental liability or the current environmental
condition of our properties will not be affected by tenants, by the condition of
land or operations in the vicinity of our properties, such as the presence of
underground storage tanks, or by third parties unrelated to us.

We believe that our properties are in compliance in all material respects
with all federal, state and local laws, ordinances and regulations regarding
hazardous or toxic substances or petroleum products, except as noted above. We
have not been notified by any governmental authority, and are not otherwise
aware, of any material noncompliance, liability or claim relating to hazardous
or toxic substances or petroleum products in connection with any of our present
properties, other than as noted above.

REPORT OF INDEPENDENT AUDITORS

Board of Directors and Stockholders
Arden Realty, Inc.

We have audited the accompanying consolidated balance sheets of Arden
Realty, Inc. as of December 31, 1999 and 1998 and the related consolidated
statements of operations, stockholders' equity, and cash flows for each of the
three years in the period ended December 31, 1999. These financial statements
are the responsibility of the management of Arden Realty, Inc. Our
responsibility is to express an opinion on these financial statements based on
our audits.

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

In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Arden Realty,
Inc. at December 31, 1999 and 1998 and the consolidated results of its
operations and its cash flows for each of the three years in the period ended
December 31, 1999, in conformity with accounting principles generally accepted
in the United States.

ARDEN REALTY, INC.

NOTES TO FINANCIAL STATEMENTS

1. BUSINESS

Description of Business

The terms "Arden Realty", "us", "we" and "our" as used in these financial
statements refer to Arden Realty, Inc. We are a self-administered and
self-managed real estate investment trust "REIT" that owns, manages, leases,
develops, renovates and acquires commercial properties located in Southern
California.

Organization and Formation of the Company

We were incorporated in Maryland in May 1996 and are the sole general
partner of Arden Realty Limited Partnership (the "Operating Partnership"). We
conduct substantially all of our business through the Operating Partnership and
certain other majority owned subsidiaries, which hold our interests in our real
estate assets. Commencing with our taxable year ended December 31, 1996, we have
operated and qualified as a REIT for federal income tax purposes.

Since our formation in 1996, we have acquired 118 properties containing
approximately 14.5 million net rentable square feet for a total purchase price
of approximately $1.9 billion. As of December 31, 1999, our portfolio consisted
of 142 primarily suburban office properties containing approximately 18.5
million net rentable square feet and three properties with approximately 700,000
net rentable square feet under development. As of December 31, 1999, our
properties were approximately 95.1% leased, excluding three existing properties
under renovation.

2. BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying consolidated financial statements include the accounts of
Arden Realty, the Operating Partnership, and its other subsidiaries. All
significant intercompany balances and transactions have been eliminated in
consolidation.

The minority interests at December 31, 1999 and December 31, 1998 consisted
of limited partnership interests in the Operating Partnership of approximately
3.3% and 4.7%, respectively, exclusive of ownership interests of our preferred
units holder.

Risks and Uncertainties

The preparation of financial statements, in conformity with generally
accepted accounting principles, requires us to make estimates and assumptions
that affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

Our properties are all located in Southern California. As a result of our
geographic concentration, the operations of these properties could be affected
by the economic conditions in this region.

Segment Information

We view our operations as principally one segment and the financial
information disclosed herein represents all of the financial information related
to our principal operating segment.

Commercial Properties

Our properties are stated at cost. When indicators of impairment exist,
write-downs to estimated fair value would be recognized if a property's
estimated undiscounted future cash flows, before interest charges,

F-6
54

are less than its book value. Based on our assessment, no write-downs to
estimated fair value were necessary as of December 31, 1999 and 1998,
respectively.

Repair and maintenance costs are charged to expenses as incurred and
significant replacements and betterments are capitalized.

Depreciation is calculated under the straight-line method using forty-year
lives for buildings, ten-year lives for building improvements and five-year
lives for furniture, fixtures and equipment. Amortization of tenant improvements
is calculated using the straight-line method over the term of the related lease.

Cash Equivalents

Cash equivalents consist of highly liquid investments with original
maturities of three months or less when acquired.

Restricted Cash

Restricted cash at December 31, 1999 and 1998 primarily consists of $13.7
million and $10 million, respectively, in cash deposits as required by certain
of our mortgage loans payable and $4.8 million and $2.4 million, respectively,
in impound accounts for real estate taxes and insurance, as required by certain
of our mortgage loans payable.

Prepaid Financing and Leasing Costs

Costs associated with leasing properties are capitalized and amortized to
expense on a straight-line basis over the related lease term. Costs associated
with obtaining long-term financing are capitalized and amortized to interest
expense over the term of the related loan.

Revenue Recognition

Minimum rent, including rental abatements and contractual fixed increases
attributable to operating leases, is recognized on a straight-line basis over
the term of the related lease. Amounts expected to be received in later years
are included in deferred rents. Property operating expense reimbursements due
from tenants for common area maintenance, real estate taxes and other
recoverable costs are recognized in the period the related expenses are
incurred.

Income Taxes

We generally will not be subject to federal income taxes as long as we
continue to qualify as a REIT. A REIT will generally not be subject to federal
income taxation on that portion of income that qualifies as REIT taxable income
and to the extent that it distributes such taxable income to its stockholders
and complies with certain requirements. As a REIT, we are allowed to reduce
taxable income by all or a portion of distributions to stockholders and must
distribute at least 95% of our taxable income to qualify as a REIT. As dividends
have eliminated taxable income, and compliance with certain requirements have
been met, no Federal income tax provision has been reflected in the accompanying
consolidated financial statements. State income tax requirements are essentially
the equivalent of the Federal rules.

During 1999, 1998 and 1997, we declared dividends of $1.78, $1.68 and $1.60
per share, respectively. For federal income tax purposes $1.63, $1.53 and $1.45
per share was reported to shareholders as ordinary income for 1999, 1998 and
1997, respectively. A total of $0.445 per share of the fourth quarter 1999
dividend will be reported to shareholders in 2000.

Fair Value of Financial Instruments

Our disclosures of estimated fair value of financial instruments at
December 31, 1999 were determined using available market information and
appropriate valuation methodologies. Considerable judgment is

F-7
55

necessary to interpret market data and develop estimated fair value. The use of
different market assumptions or estimation methodologies may have a material
effect on the estimated fair value amounts.

Our cash equivalents, mortgage notes receivable, accounts payable, the
lines of credit and other financial instruments are carried at amounts that
reasonably approximate their fair value amounts. The unrealized gain on our
mortgage notes payable at December 31, 1999 was approximately $20.4 million.
Estimated fair value is based on interest rates currently available for issuance
of debt with similar terms and remaining maturities.

Reclassifications

Certain prior year amounts have been reclassified to conform with the
current year presentation.

3. COMMERCIAL PROPERTIES

The following table sets forth certain information regarding our
acquisition of office properties for the year ended December 31, 1999.

4. MORTGAGE NOTES RECEIVABLE

In September 1997, we purchased two mortgage notes receivable, secured by a
single commercial office property, with an aggregate balance of approximately
$17.6 million, for approximately $14.4 million. The notes bear interest at the
Eleventh District Cost of Funds plus 3.25% per annum, require monthly payments
of principal, interest, and additional net cash flow from the office property
and mature on May 31, 2004. These notes had an effective interest rate of 7.9%
at December 31, 1999.

Center.

Mortgage Loans Payable

On April 5, 1999, we closed a $115 million loan with Mass Mutual Life
Insurance Company (the "Mortgage Financing V"). Proceeds from this loan were
used to repay $76.4 million of our Lehman Prepayable Term Loan I and to repay a
portion of our unsecured lines of credit. On April 30, 1999 we closed a $22.5
million loan with Lehman Brothers, Limited Partnership (the "Mortgage Financing
VI"). Proceeds from this loan were used to repay a portion of our unsecured
lines of credit. On May 5, 1999, we refinanced the remaining $35 million
outstanding under the Lehman Prepayable Term Loan I with one secured note
payable totaling $62.5 million (the "Lehman Prepayable Term Loan II") to an
affiliate of Lehman Brothers. The remaining proceeds from this loan were used to
repay a portion of our unsecured lines of credit.

On July 23, 1999, we entered into a construction loan with a total
commitment of $50 million (the "Construction Loan") related to our development
of the approximately 241,000 net rentable square foot Center Drive office
building in the Howard Hughes Center. Subject to meeting certain construction
completion and leasing benchmarks, as defined, the interest rate on the
Construction Loan may be reduced to LIBOR plus 1.75%, then to LIBOR plus 1.5%.
As of December 31, 1999, there was $22.0 million outstanding on the Construction
Loan and $28 million was available for additional borrowing.

On July 27, 1999, we closed a $58 million loan with Lehman Brothers, Inc.
(the "Lehman Prepayable Term Loan III"). Proceeds from this loan were used to
repay a portion of our unsecured lines of credit and to fund certain capital
expenditures. In January 2000, we expanded this loan from $58 million to $83
million.

In connection with two of our mortgage loans payable to an affiliate of
Lehman Brothers, we entered into a treasury rate lock agreement, or the swap
agreement, with a notional amount of $100 million and locked in the United
States 10-year treasury rate at 6.174%. On April 16, 1998, we settled the swap
agreement for $4.5 million and are amortizing the cost of settling the swap
agreement over the term of the two related mortgage loans payable to an
affiliate of Lehman Brothers.

Following is a summary of scheduled principal payments for our mortgage
loans as of December 31, 1999 (in thousands):

Unsecured Lines of Credit

As of December 31, 1999 and 1998, we had an unsecured line of credit in the
amount of $300 million with a group of banks led by Wells Fargo Bank. This line
of credit has an interest rate that ranges between LIBOR plus 1.2% and LIBOR
plus 1.45%, depending on our leverage ratio. The effective interest rate at
December 31, 1999 was 7.52%. The interest rate may be lowered to between LIBOR
plus 0.9% and LIBOR plus 1.15%, depending on our unsecured debt rating. Under
certain circumstances, we have the option to convert the interest rate to the
prime rate plus 0.5%. The outstanding principal balance of this line of credit
was $280.9 million and $296.4 million at December 31, 1999 and 1998,
respectively.

F-10
58

This line of credit is subject to customary conditions to borrowing;
contains representations, warranties and defaults customary in REIT financings;
and contains financial covenants, including requirements for a minimum tangible
net worth, maximum liabilities to asset values, and minimum interest, unsecured
interest and fixed charge coverage ratios, all calculated as defined in the
Wells Fargo line of credit documentation, and requirements to maintain a pool of
unencumbered properties that meet certain defined characteristics and are
approved by the group of banks led by Wells Fargo Bank. This line of credit also
contains restrictions on, among other things, indebtedness, investments,
distributions, liens and mergers. In addition, this line of credit has a
commitment fee ranging from 0.125% to 0.25% on the unused balance. This line of
credit matures on June 1, 2000. Proceeds from this line of credit have been
used, among other things, to provide funds for tenant improvements and capital
expenditures and provide for working capital and other purposes.

As of December 31, 1999 and 1998 we also had an unsecured line of credit in
the amount of $10 million with City National Bank.

In January 1997, we entered into interest rate floor and cap transactions
with a notional amount of $155.0 million to hedge our exposure to variable
interest rates. We entered into these agreements to convert floating rate
liabilities to fixed rate liabilities. In July 1997, we repaid all of our
outstanding floating rate debt at the time with proceeds from an equity offering
and in October 1997, the swap agreement was retired resulting in a loss on the
derivative of $3.1 million.

6. STOCKHOLDERS' EQUITY

On September 7, 1999, we completed a $50 million private placement of
8 5/8% Series B Cumulative Redeemable Preferred operating partnership units, or
Preferred Op Units, to an institutional investor. The Preferred OP Units are
callable by us after five years and are exchangeable after ten years by the
holder into our 8 5/8% Series B Cumulative Redeemable Preferred Stock, on a
one-for-one basis. The Preferred OP Units have no stated maturity or mandatory
redemption and are subordinate to all debt. We used the net proceeds from this
private placement to repay a portion of our lines of credit.

On January 12, 1998, we filed a form S-3 Registration Statement, or the
Registration Statement, with the Securities Exchange Commission to offer in one
or more series, shares of our $.01 par value common stock with an aggregate
public offering price of up to $1.0 billion. This Registration Statement was
declared effective on January 21, 1998.

During 1998, we completed four equity offerings under the Registration
Statement, as follows (in thousands):

(a) Shares of common stock issued to the trustees of unrelated registered unit
investment trusts.

(b) Excludes 229,880 shares issued in connection with Operating Partnership Unit
conversions and 85,106 shares issued to officers for purchases of common
stock .

There were no equity offerings under the Registration Statement during
1999.

An Operating Partnership Unit, or OP Unit, and a share of common stock have
essentially the same economic characteristics as they share equally in the total
net income or loss and distributions of the Operating Partnership. An OP Unit
may be redeemed for cash or, at our election, for shares of common stock on a
one-for-one basis.

F-11
59

During 1998, we issued 300,255 common OP Units, valued at approximately
$8.2 million in connection with certain property acquisitions. During 1998, we
also redeemed 542,382 common OP Units at a cost of approximately $16.3 million
in cash based on the original issuance price of the related common OP Units.

A dividend was declared on December 1, 1999 to stockholders of record on
December 31, 1999 of $0.445 per common share, for the quarter ended December 31,
1999. This dividend was paid on January 27, 2000. Arden Realty declared
dividends of $1.78 per common share for the year ended December 31. 1999.

7. COMMITMENTS AND CONTINGENCIES

Capital Commitments

As of December 31, 1999, we had approximately $23.6 million outstanding in
capital commitments related to tenant improvements, renovation costs and general
property-related capital expenditures.

Litigation

We do not believe there is any litigation threatened against us other than
routine litigation arising out of the ordinary course of business, some of which
is expected to be covered by liability insurance and all of which is not
expected to have a material adverse effect on our consolidated financial
statements.

Concentration of Credit Risk

We maintain our cash and cash equivalents at financial institutions. The
combined account balances at each institution periodically exceed FDIC insurance
coverage, and as a result, there is a concentration of credit risk related to
amounts on deposit in excess of FDIC insurance coverage. Management believes
that the risk is not significant.

We generally do not require collateral or other security from our tenants,
other than security deposits.

8. RELATED PARTY TRANSACTIONS

Promissory Notes Receivable from Officers

In August 1998, we issued 85,106 shares of common stock, related to the
issuance of 42,553 shares of common stock to each of two executive officers. In
consideration for the issuance of the common stock, the executive officers
executed promissory notes in the amount of $1 million each.

The promissory notes are recourse and secured by the shares of common stock
issued to the executive officers, bear interest at 6% per year with all accrued
interest and principal due on August 14, 2004. Provided that the executive
officers are still employed by us, the outstanding principal amount of the
promissory notes will be forgiven as follows; August 14, 2001, $100,000; August
14, 2002, $166,667; August 14, 2003, $200,000; and August 14, 2004, $200,000.
Additionally, provided that the executive officers are still employed by us, all
accrued and unpaid interest and the outstanding principal amount of the
promissory notes will be forgiven upon a change in control, as defined in the
promissory note, of us or upon the death or disability of the executive
officers. See Note 14.

11. STOCK OPTION PLAN

We have elected to follow Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees" ("APB 25") and related
interpretations in accounting for our employee and directors stock options
because, as discussed below, the alternative fair value accounting provided for
under FASB Statement No. 123, "Accounting for Stock-Based Compensation"
("Statement 123") requires use of option valuation models that were not
developed for use in valuing employee stock options. Under Statement 123,
because the exercise price of employee and director stock options we granted
equals the market price of the underlying stock on the date of grant, no
compensation expense is recognized.

We established a stock option plan for the purpose of attracting and
retaining executive officers, directors and other key employees. As of December
31, 1999, 4,200,000 of our authorized shares of common stock have been reserved
for issuance under that plan.

All holders of the above options have a ten-year period to exercise and all
options were granted at exercise prices equal to the market prices at the date
of the grant.

F-13
61

Pro forma information regarding net income and earnings per share is
required by Statement 123, and has been determined as if Arden Realty had
accounted for its employee stock options under the fair value method of that
Statement. The fair value for these options was estimated at the date of grant
using a Black-Scholes option pricing model with the following weighted-average
assumptions for 1999, 1998 and 1997, respectively: risk-free interest rate of
6.67%, 5.68%, and 5.81%; dividend yield of 5.79%, 7.25% and 5.2%; volatility
factor of the expected market price of Arden Realty's common stock of .245,
.268, and .194. The weighted average expected life of the options ranges between
eight and 10 years.

The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options which have no vesting restriction
and are fully transferable. In addition, option valuation models require the
input of highly subjective assumptions including the expected stock price
volatility. Because our employee and director stock options have characteristics
significantly different from those of traded options, and because changes in the
subjective input assumptions can materially affect the fair value estimate, in
management's opinion, the existing models do not necessarily provide a reliable
single measure of the fair value of our employee and director stock options.

For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting periods. Our pro forma
information for the years ended December 31, 1999, 1998 and 1997 follows (in
thousands, except earnings per share information):

Exercise prices for options outstanding as of December 31, 1999 ranged from
$19.13 to $32.25. The weighted average remaining contractual life of those
options is 8.4 years.

12. EMPLOYEE RETIREMENT SAVINGS PLAN

Effective June 12, 1997, we adopted a retirement savings plan pursuant to
Section 401(k) of the Internal Revenue Code whereby participants may contribute
a portion of their compensation to their respective retirement accounts in an
amount not to exceed the maximum allowed under the Code. The plan provides for
matching contributions by us, which amounted to approximately $385,000 in 1999,
$187,000 in 1998 and $71,000 in 1997. Plan participants are immediately vested
in their contributions and are vested equally over four years in matching
contributions by us.

13. YEAR 2000 -- UNAUDITED

In 1999, we completed our remediation and testing of systems with respect
to the Year 2000 date change. As a result of our planning and implementation
efforts, we experienced no significant disruptions in mission

F-14
62

critical information technology and non-information technology systems and
believe those systems successfully responded to the Year 2000 date change. We
incurred costs of approximately $500,000 during 1999 in connection with
remediating our systems. We are not aware of any material problems resulting
from Year 2000 issues, either with our products, our internal systems or the
products and services of third parties. We will continue to monitor our mission
critical computer applications and those of our suppliers and vendors throughout
the year to ensure that any latent Year 2000 matters that may arise are
addressed promptly.

14. SUBSEQUENT EVENT -- UNAUDITED

Promissory Note Receivable From Officers

Andrew Sobel resigned as Executive Vice President and Director of Property
Operations effective February 18, 2000. At the time of his termination, Mr.
Sobel surrendered the common stock underlying his promissory note, discussed in
Note 8 above, and executed a new promissory note in the amount of $223,887,
representing the difference between the value of the common stock surrendered
and the unpaid principal and interest on his original promissory note. The new
promissory note bears interest at 6.56%, with all accrued interest and principal
due on February 18, 2002. In addition, effective with his termination, Arden
Realty and Mr. Sobel entered into a consulting and non-competition agreement for
a term of two years. Under this agreement, Mr. Sobel will receive compensation
of $6,000 per month, which will be applied against the unpaid interest and
principal on the new promissory note.

Debt Offering

On March 17, 2000, the Operating Partnership issued $250 million of senior
unsecured notes in two tranches, with $200 million at an interest rate of 8.875%
due in March 2005 and $50 million at an interest rate of 9.150% due in March
2010. These notes will be the Operating Partnership's senior unsecured
obligations and pay interest semi-annually on March 1, and September 1, of each
year. Net proceeds from this offering were used to repay two prepayable term
loans to an affiliate of Lehman Brothers described above totaling $145.5
million, a $5.0 million mortgage loan and approximately $96.1 million under our
unsecured lines of credit. These senior unsecured notes were issued in a private
placement in reliance upon an exemption from registration provided by Section
144(a) under the Securities Act. As part of issuing these notes, the Operating
Partnership has agreed to file a registration statement with the Securities and
Exchange Commission within 90 days after the notes are issued, enabling the
holders of the notes to exchange the privately placed notes for publicly traded
notes with identical terms other than those pertaining to transfer restrictions
and liquidated damages.

Dividend Declaration

On March 17, 2000, we declared a first quarter dividend of $0.465 per share
to shareholders of record on March 31, 2000.
