ITEM 1. BUSINESS

(a) GENERAL

       The terms "us", "we" and "our" as used in this report refer to Arden
Realty Limited Partnership. The term "Arden Realty" refers to Arden Realty, Inc.
We are an operating partnership that owns, manages, leases, develops, renovates
and acquires commercial properties located in Southern California. Arden Realty,
a real estate investment trust, or REIT, is our sole general partner and, as of
December 31, 2000, owned 96.7% of our common partnership units, or common OP
Units.

(b) INDUSTRY SEGMENTS

       We are currently involved in only one industry segment, namely the
operation of commercial real estate located in Southern California. 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 experience in the real estate industry ranging from
8 to 30 years and who collectively have an average of 18 years of experience. We
perform all property management, construction management, accounting, finance
and acquisition activities and a majority of our leasing transactions for our
portfolio with our staff of approximately 300 employees.

       As of December 31, 2000, we were Southern California's largest publicly
traded office landlord as measured by total net rentable square feet owned.
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, 2000, our portfolio consisted
of 142 primarily office properties containing approximately 18.7 million net
rentable square feet and three properties with approximately 725,000 net
rentable square feet under development. As of December 31, 2000, our properties
were approximately 95.5% leased.

       PORTFOLIO MANAGEMENT

       We perform all portfolio management activities, including management of
all lease negotiations, construction management of tenant improvements, or
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 four 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 managed by a regional manager who is responsible for supervising
the day-to-day activities of our management offices. Each regional office is
staffed with leasing, property management, building engineering, construction
and information systems specialists, our Regional Service Teams. By maintaining
a regionally focused organizational structure headed by seasoned managers, we
are able to quickly respond to our tenants' needs and market opportunities.

       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.

       We currently lease approximately 70% of our properties using our in-house
staff. We employ outside brokers who are monitored by our regional managers for
the remainder of our properties. Our in-house leasing program allows us to
closely monitor rental rates and lease terms for new and renewal leases and
reduce third-party leasing commissions.


                                       3

       BUSINESS STRATEGIES

       Our primary business strategy is to actively manage our portfolio to
achieve gains in rental rates and occupancy, to control operating expenses and
to maximize income from ancillary operations and services. When market
conditions permit, we may also selectively develop or acquire new properties in
submarkets that add value and fit strategically into our portfolio. We may also
sell existing mature or slow growth properties and deploy the proceeds into
investments that we believe will generate higher yields.

       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
portfolio.

              INTEGRATED DECISION MAKING

       We use a multidisciplinary approach to our decision making by having our
management, leasing, construction management, acquisition, disposition 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, acquisition or disposition terms quickly, which facilitates an
efficient completion of lease negotiation and tenant build-out, shorter vacancy
periods after lease expirations and the timely completion of development,
acquisition or disposition 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 outside
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 2000, we
signed approximately 1,000 leases for approximately 4.5 million net rentable
square feet, including approximately 513,000 square feet of net absorption. We
consider net absorption to consist of the total square feet of new and renewal
leases signed less the total square feet of leases expired during a particular
period.

              COST CONTROL AND OPERATING EFFICIENCIES

       The size and geographic focus of our portfolio permits us to enhance
portfolio value by controlling 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


                                       4
<PAGE>   5

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 sound fundamentals of the Southern California real estate
              market, as measured by declining vacancy rates and increasing
              rental rates, particularly in the submarkets where our properties
              are located;

       -      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; and

       -      the strong diversification of the Southern California economy and
              our tenant base minimizes the dependence on any one industry
              segment.

              INTERNAL GROWTH

       We believe that opportunities exist to increase cash flow from our
existing portfolio. We intend to pursue internal growth by:

       -      leasing space and renewing leases as they expire at increasing
              rents and maximizing scheduled rent increases throughout the new
              lease term;

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

       -      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 needs, or moved to other
space within our portfolio.

              Leasing Space and Renewing Leases as They Expire at Increasing
Rents

       Rental rates for the majority of our leases are significantly lower than
the current market rental rates. In 2000, vacancy rates decreased and average
rental rates increased in our markets. During 2000, for all leases expiring that
we renewed or released, rates increased approximately 20% over the expiring
rates. Although it is difficult to predict future trends, we believe we will
have opportunities to increase cash flow by renewing or re-leasing space at
higher rents as leases expire and to maximize scheduled rent increases
throughout the new lease terms.


                                       5
<PAGE>   6

              Cost Control Management and Systems

       We plan to continue controlling our operating expenses through active
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 Regional Service Teams
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. In 1999, we entered into 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 at their cost. During 2000 we
completed the installation of this network. In addition to high speed Internet
services, this network provides 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 sound fundamentals, diversity 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 selective
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;


                                       6
<PAGE>   7

       -      a minimal amount of developable land; and

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

       COMPETITION

       We compete with other owners and developers of office properties to
attract tenants to our properties and obtain suitable land for development.
Ownership of competing properties is currently diversified among many different
types, from publicly traded companies and institutional investors, including
other REITs, small enterprises and individual owners. No one owner or group of
owners currently dominate or significantly influence the markets in which we
operate. See "Risk Factors - Competition affects occupancy levels, rents and the
cost of land which could adversely affect our revenues."

       CALIFORNIA ELECTRIC UTILITY DEREGULATION

       Problems associated with deregulation of the electric industry in
California have resulted in intermittent service interruptions and significantly
higher costs in some areas. Approximately 55% of our buildings and 56% of the
total net rentable square footage of our portfolio are located within
municipalities that either do not produce their own power or have not entered
into long term fixed price contracts. These properties may be subject to
intermittent service interruptions or rate increases from their utility
providers. The remaining portion of our portfolio is located in areas that are
not expected to be subject to intermittent electric service interruptions and
significant electric rate increases.

       Approximately 19% of our buildings and 15% of the total net rentable
square footage of our portfolio are subject to leases that require our tenants
to pay all utility costs and the remainder provide that our tenants will
reimburse us for utility costs in excess of a base year amount. We estimate that
we will be able to recover approximately 90% of any utility cost increases from
our tenants. See "Risk Factors - Rising energy costs and power outages in
California may have an adverse effect on our operations and revenue."

       Since 1999, Arden has applied considerable resources to energy
enhancement programs with the aim of reducing energy consumption, enhancing
efficiency and lowering operating costs. For the past two years, we have been
recognized by the Environmental Protection Agency with the national Commercial
Real Estate Partner of the Year award for our performance in the Energy Star
Program. The competition involves top commercial real estate landlords
throughout the United States and rigorous bench-marking procedures that track
individual building energy efficiency. Of the 215 total Energy Star designated
office buildings awarded nationally, 93 were awarded in California, of those, we
had 80 award-winning buildings and were cited for having the most energy
efficient buildings within a single portfolio in the nation.

       We are also working with other companies to provide new applications of
Distributed Generation, or on-site energy systems, such as solar microturbines,
natural gas reciprocating engines, fuel cells and other "green" power
alternatives. Lastly, we maintain ongoing communication with our tenants to
assist them in ways to lower consumption in their workplace.

       EMPLOYEES

       As of December 31, 2000, we had approximately 300 full-time employees
that perform all of our property management, construction 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.

<PAGE>   8

       Our portfolio consists of 142 primarily office properties, containing
approximately 18.7 million net rentable square feet, that individually range
from approximately 12,000 -- 600,000 net rentable square feet. Of the 142
properties in our portfolio, 137 or 96% are office properties. All our
properties are located in Southern California and most are in suburban areas in
close proximity to main thoroughfares. 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 high speed
internet access, security, parking, conference facilities, on-site management,
food services and health clubs.

       Following is a summary of our property portfolio as of December 31, 2000:

----------

(1)    Calculated as monthly contractual base rent under existing leases as of
       December 31, 2000, multiplied by 12 and divided by leased net rentable
       square feet; 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 47 properties and approximately 4.1 million net rentable square
       feet under triple net and modified gross leases. Triple net and modified
       gross leases are those where tenants pay not only base rent but also some
       or all real estate taxes and operating expenses of the leased property.
       If these properties and square footage had been included, our total
       weighted average annualized base rent per leased net rentable square foot
       would be $19.75.

       Development Properties

       In addition to the properties listed above, we currently have three
properties under development containing approximately 725,000 net rentable
square feet. These properties are located in the Howard Hughes Center, a 70-acre
commercial development located two miles north of Los Angeles International
Airport and immediately adjacent to the San Diego Freeway (I-405), with on- and
off-ramps that directly serve the site.

       The following table summarizes information about our properties under
development as of December 31, 2000.

----------

(1)    Estimated total cost includes purchase and closing costs, capital
       expenditures, tenant improvements, leasing commissions and carrying costs
       during development, as well as an allocation of land and master plan
       costs. Unallocated acquisition and master plan costs consists of
       unallocated land costs, the costs of road and bridge construction and
       other Howard Hughes Center infrastructure and master plan costs that will
       be allocated to future development projects at the Howard Hughes Center.
       We have entitlements to construct an additional approximately 425,000 net
       rentable square feet of office space at the Howard Hughes Center.

(2)    We consider a property to be stabilized in the quarter when the property
       is at least 95% leased.

(3)    We consider Stabilized Cash NOI to be the rental revenues from the
       property less the operating expenses of the property on a cash basis
       before deducting financing costs (interest and principal payments) after
       the property is at least 95% leased.

                     In addition to the properties above, we have preliminary
              architectural designs completed for additional build-to-suit
              buildings at the Howard Hughes Center, totaling an additional
              approximately 425,000 net rentable square feet. Build-to-suit
              buildings consist of properties constructed to the tenant's
              specifications in return for the tenant's long term commitment to
              the property. We do not intend to commence construction on any
              additional build-to-suit buildings at the Howard Hughes Center
              until development plans and budgets are finalized, build-to-suit
              tenant leases are signed with terms allowing us to achieve yields
              commensurate with the project's development risk.

                     In addition to our development at the Howard Hughes Center,
              we have completed preliminary designs and are marketing an
              approximately 170,000 net rentable square foot build-to-suit
              office building at our Long Beach Airport Business Park. We do not
              intend to commence construction on this project until a
              build-to-suit tenant lease is signed with terms allowing us to
              achieve yields commensurate with the project's development risk.

                     We expect to finance our development activities over the
              next 24 months through net cash provided by operating activities,
              proceeds from asset sales or proceeds from our lines of credit.

                     Acquisitions

                     We did not acquire any properties in 2000.

       Dispositions

       On October 13, 2000, we sold a 76,000 net rentable square foot retail
property located in Thousand Oaks, California, for approximately $12.0 million
and recorded a gain of approximately $2.1 million.

       As of December 31, 2000, we had approximately $59.6 million of properties
held for sale. We intend to reinvest the net proceeds from the sale of these
mature or slow growth assets into higher yielding investments.

----------

(1)    Calculated as monthly contractual base rent under existing leases as of
       December 31, 2000, multiplied by 12 and divided by leased net rentable
       square feet, 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)    We lease the land underlying those properties or their parking structures
       pursuant to long term ground leases.

(3)    Amounts for 2730 Wilshire exclude the 100%-occupied 12,740 square foot,
       16-unit apartment complex we also own.

       Tenant Information

       As of December 31, 2000, we had over 3,000 tenants, with no one tenant
representing more than 2.1% of the aggregate annualized base rent of our
properties, and only two 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, education and
publishing and local, state and federal government entities.

       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. Approximately 78% of our total leased
rentable square footage is under full service gross leases under which tenants
typically pay for all real estate taxes and operating expenses above those for
an established base year or expense stop. Our remaining square footage is under
triple net and modified gross leases. Triple net and modified gross leases are
those where tenants pay not only base rent, but also some or all real estate
taxes and operating expenses of the leased property. Tenants generally reimburse
us the full direct cost, without regard to a base year or expense stop, for use
of lighting, heating and air conditioning during non-business hours, and for
on-site monthly employee and visitor parking. We are generally responsible for
structural repairs.

(1)    Excludes two leases with a division of Vivendi Universal Publishing for
       approximately 217,000 square feet comprising approximately 1.22% of the
       aggregate portfolio leased square footage with a weighted average lease
       term of 120 months that will begin in 2001.  Assuming these leases had
       been in place at December 31, 2000, this tenant would have ranked first
       in our list of largest tenants with approximately 2.25% of aggregate
       annualized base rent.

(2)    Annualized base rent is calculated as monthly contractual base rent under
       existing leases as of December 31, 2000, multiplied by 12; for those
       leases where rent has not yet commenced or which are in a free rent
       period, the first month in which rent is to be received is used to
       determine annualized base rent.

(3)    The weighted average calculation is based on net rentable square footage
       leased by each tenant.

       We make quarterly distributions to our common OP Unit holders at the
discretion of Arden Realty, our sole general partner. The amount of each
quarterly distribution depends 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 Arden Realty
deems relevant.

(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.

       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 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 real
       estate companies and, accordingly, our funds from operations may not be
       comparable to those companies' funds from operations.

(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 full service real estate organization that owns, manages,
leases, develops, renovates and acquires commercial properties located in
Southern California. We are managed by 11 senior executive officers who have
experience in the real estate industry ranging from 8 to 30 years and who
collectively have an average of 18 years experience. We perform all property
management, construction management, accounting, finance and acquisition
activities and a majority of our leasing transactions with our staff of
approximately 300 employees. Arden Realty, a publicly traded REIT, is our sole
general partner, and, as of December 31, 2000, owned 96.7% of our common OP
Units. Arden Realty conducts substantially all of its operations through us and
our subsidiaries.

       As of December 31, 2000, we are Southern California's largest publicly
traded office landlord as measured by total net rentable square feet owned. As
of that date, our portfolio consisted of 142 primarily suburban office
properties containing approximately 18.7 million net rentable square feet and
three properties with approximately 725,000 net rentable square feet under
development. As of December 31, 2000, our properties were approximately 95.5%
leased.

       Our primary business strategy is to actively manage our portfolio to
achieve gains in rental rates and occupancy, control operating expenses and to
maximize income from ancillary operations and services. When market conditions
permit, we may also selectively develop or acquire new properties that add value
and fit strategically into our portfolio. We may also sell existing mature or
slow growth properties and redeploy the proceeds into investments that we
believe will generate higher yields.

       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 will be affected by the timing
of significant property renovations, developments, acquisitions and
dispositions.

       Variances for revenue from rental operations and property expenses are
discussed below.

       Interest and other income increased by approximately $705,000 in 2000 as
compared to 1999, primarily due to increases in management fees for owner
associations we manage and from higher interest income earned in 2000 on higher
restricted cash balances required by mortgage loans entered into after January
1, 1999.


                                       24
<PAGE>   25

       General and administrative expenses were approximately $8.3 million, or
2.1% of total revenue, in 2000 as compared to $6.8 million, or 2.0% of total
revenue, in 1999. This increase was primarily related to higher personnel costs
in 2000, including $586,000 related to the non-cash compensation expense from
restricted stock awards granted to several key executives.

       Interest expense increased approximately $18.2 million in 2000 as
compared to 1999. This increase was primarily due to both higher outstanding
balances in 2000, resulting from the funding of acquisitions, tenant
improvements, leasing commission costs and development and renovation projects
placed in service during the periods presented, and higher average interest
rates in 2000.

       Depreciation and amortization expense increased by approximately $17.4
million in 2000, primarily due to depreciation related to properties acquired in
1999, newly developed and renovated properties, and capital expenditures, tenant
improvements and leasing commissions placed in service in 2000.

VARIANCES FOR REVENUE FROM RENTAL OPERATIONS AND PROPERTY OPERATING EXPENSES

       The increase in revenue from rental operations and property operating
expenses in 2000 as compared to 1999 was partially due to the four properties we
acquired during 1999, a development property placed in service in the third
quarter of 2000, a property sold in the fourth quarter of 2000 and the five
properties under renovation for all or a portion of the periods presented.
Operating results for properties under renovation may significantly vary from
period to period depending on the extent and status of the renovation and
occupancy levels maintained during the renovation.

       Following is a summary of the increase in revenue from rental operations
and property operating expenses that relates to the eleven properties that were
either acquired, sold or placed in service after January 1, 1999 or were under
renovation for all or a portion of the period beginning after January 1, 1999
and for the 132 non-renovation properties we owned for all 1999 and 2000 (in
thousands, except number of properties).

----------

(1)    Excludes straight-line rent adjustments.

       Revenue from rental operations for these properties, computed on a GAAP
basis, increased by approximately $21.1 million, or 6.6%, during 2000, compared
to 1999. Approximately $18.7 million of this increase was from rental revenue,
of which $17.0 million was related to scheduled rents and $1.7 million was from
straight-line rent. Approximately 55% of the increase in scheduled rents was due
to increases in rental rates in 2000 and the remaining 45% was related to higher
average occupancy in 2000. The increase in straight-line rent was primarily due
to new leases and extensions signed with higher rental rate escalations than in
1999. Revenue from rental operations was also higher due to an approximate $2.3
million increase in tenant reimbursements, a $2.5 million increase in parking
income net of an approximate $2.4 million decrease in other revenue from rental
operations. In addition to recoveries of approximately $688,000 from increases
in utility rates for our San Diego properties, tenant reimbursements and parking
income primarily increased due to the approximate 1.2% increase in average
occupancy in 2000, while other rental operations decreased primarily due to
lower lease termination settlements fees in 2000.

       Excluding only the straight-line rent adjustment for these properties,
revenue from rental operations computed on a cash basis, increased by
approximately $19.4 million or 6.2%.

       Property operating expenses for these properties increased by
approximately $3.9 million, or 4.1%, during 2000, compared to 1999, primarily
due to higher real estate taxes, repairs and maintenance, contingent ground
rent and property administrative expenses in 2000. Real estate taxes increased
by approximately $2.2 million in 2000 due to normal annual increases and final
assessments on certain properties. Repairs and maintenance increased by $533,000
primarily due to the 1.2% increase in average occupancy in 2000. Ground rent
expense increased by $323,000 due to higher operating income from one of our
properties with a participating ground lease. Property administrative expenses,
comprised primarily of personnel and related costs, were also approximately
$666,000 higher in 2000, primarily due to our continued focus on raising
portfolio-wide occupancy. Our utility costs increased by approximately $135,000
in 2000 due to both higher average occupancy and rate increases for our San
Diego properties, partially offset by savings achieved from energy enhancing
capital improvements completed during 1999.

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

       General and administrative expenses were approximately $6.8 million, or
2.0% of total revenue, in 1999 as compared to $6.3 million, or 2.2% 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
1998 and 1999 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 administrative and overhead expenses. These increases
were primarily related to the four percentage point increase in average
occupancy in 1999.

       LIQUIDITY AND CAPITAL RESOURCES

       Cash Flows

       Cash provided by operating activities increased by approximately $23.8
million to $194.3 million for the year ended December 31, 2000, as compared to
$170.5 million for the year ended December 31, 1999, primarily due to improved
operating results for the 132 properties we owned for all of 1999 and 2000, as
well as the net operating results of the eleven properties we developed,
renovated or acquired subsequent to January 1, 1999.

       Cash used in investing activities decreased by approximately $67.6
million to $216.0 million in 2000 compared to $283.6 million in 1999. This
decrease was primarily due to $89.8 million used in 1999 to acquire four
properties which was partially offset by an increase of approximately $14.4
million used in 2000 for capital expenditures related to our increased
development and renovation activity and additional costs associated with tenant
improvement build-outs resulting from occupancy gains achieved in 2000.


                                       29
<PAGE>   30

       Cash provided by financing activities decreased by $95.5 million to $20.1
million, as compared to $115.6 million in 1999. This decrease was primarily due
to the timing of an equity issuance. In September 1999, we issued $50 million in
8-5/8% Series B Cumulative Redeemable Preferred Operating Units. Cash provided
by financing activities for the year ended December 31, 2000 consisted primarily
of net proceeds from our offerings of unsecured senior notes, partially offset
by repayments of mortgage loans, paydowns of our unsecured lines of credit and
distributions to our stockholders and minority interests.

       Capital Commitments

       As of December 31, 2000, we had approximately $14.1 million outstanding
in capital commitments related to tenant improvements, development and
property-related capital expenditures. We expect to fund short term capital
commitments through cash flow generated by operating activities and proceeds
from asset sales or proceeds from our lines of credit.

       Available Borrowings, Cash Balances and Capital Resources

       On May 3, 2000, we extended our unsecured line of credit with a group of
banks led by Wells Fargo. The extended line of credit provides for borrowings up
to $275 million with an option to increase the amount to $325 million and bears
interest at a rate ranging between LIBOR plus 1.15% and LIBOR plus 1.80%
(including an annual facility fee ranging from .20% to .40% based on the
aggregate amount of the facility) depending on our unsecured debt rating. In
addition, as long as we maintain an unsecured debt rating of BBB-/Baa3 or
better, the agreement contains a competitive bid option, whereby the Lenders
under this line of credit may bid on the interest rate to be charged for up to
$137.5 million of the unsecured line of credit. Under certain circumstances, we
also have the option to convert the interest rate on this line of credit to the
prime rate plus 0.5%. This line of credit matures in April 2003. As of December
31, 2000, there was approximately $172.4 million outstanding on this line of
credit and approximately $102.6 million was available for additional borrowings.

       In July 2000, we closed on a $75 million unsecured line of credit with
Lehman Brothers. Borrowings on this new line of credit bear interest at a rate
ranging between LIBOR plus 1.05% and LIBOR plus 1.70%, depending on our
unsecured debt rating. We also have the option to convert the interest rate to
the prime rate plus 0.5%. This line of credit matures in July 2002 with an
option to extend the maturity date for one year. Proceeds from this line of
credit have been used to reduce the outstanding balance under our $275 million
line of credit. As of December 31, 2000, there was $75 million outstanding on
this line of credit.

       In August 2000, we extended our unsecured line of credit with a total
commitment of $10 million from City National Bank to August 2001. This line of
credit accrues interest at the City National Bank Prime Rate less 0.875%. As of
December 31, 2000, there was an outstanding balance of $6.0 million, and $4.0
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.

       As of December 31, 2000 we had approximately $106.6 million available
under our unsecured lines of credit.

       On March 17, 2000, we issued $250 million of senior unsecured notes in
two tranches. One tranche was for $200 million at an interest rate of 8.875% due
in March 2005 and the other tranche was for $50 million at an interest rate of
9.150% due in March 2010. These notes are our 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 a mortgage loan and to reduce the outstanding
balance 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 Rule 144A under the Securities Act. We subsequently filed a
registration statement that became effective on May 10, 2000 and all privately
placed notes were exchanged for notes registered under the Securities Act.

       On November 20, 2000, we completed a private placement of $100 million
8.50% senior notes due in November 2010, with interest payable semi-annually on
November 15 and May 15 of each year. We used the net proceeds from this private
placement to reduce the outstanding balance on one of our unsecured lines of
credit and to repay a construction loan related to our development of the 6060
Center Drive project. These senior unsecured notes were issued in a private
placement in reliance upon an exemption from registration provided by Rule 144A
under the Securities Act. We subsequently filed a registration statement that
became effective on

       March 29, 2001 and are currently exchanging these privately placed notes
for registered notes. We expect to complete this exchange offer by April 26,
2001.

(1)    Includes amortization of prepaid financing costs.

       As of December 31, 2000, we had approximately $24.8 million in cash and
cash equivalents, including $19.4 million in restricted cash, including $13.9
million in interest-bearing cash deposits required by some of our mortgage loans
payable. In addition, we had $5.5 million in cash impound accounts for real
estate taxes and insurance as required by several of our mortgage loans payable.

       We may sell mature or slow growth assets over the next twelve to
twenty-four months. Due to market conditions beyond our control, it is difficult
to predict the actual period and amount of these asset sales. At the time any
such sales proceeds are realized, we expect to redeploy such amounts into
investments that we believe will generate higher yields, which may include
development of office buildings, acquisitions or repurchase of our common stock.
In addition, we expect to use a portion of any proceeds to pay down portions of
our debt in order to maintain our conservative leverage and coverage ratios.

       We expect to continue meeting our short-term liquidity and capital
requirements generally through net cash provided by operating activities and
proceeds from our lines of credit or proceeds from asset sales. We believe that
the net cash provided by operating activities will continue to be sufficient to
pay any distributions necessary to enable Arden Realty to continue qualifying as
a REIT. We also believe the foregoing sources of liquidity will


                                       31
<PAGE>   32

be sufficient to fund our short-terms liquidity needs over the next twelve
months, including recurring non-revenue enhancing capital expenditures, tenant
improvements and leasing commissions.

       We expect to meet our long-term liquidity and capital requirements such
as scheduled principal repayments, development costs, property acquisitions, if
any, and other non-recurring capital expenditures through net cash provided by
operations, the refinancing of existing indebtedness, proceeds from asset sales
and/or the issuance of long-term debt and equity 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 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 real estate companies and, accordingly,
       our funds from operations may not be comparable to those companies' funds
       from operations.


(2)    Includes $586,000 in non-cash compensation expense.


(3)    Funds available for distribution consists of funds from operations,
       excluding straight-line rent adjustments and less a reserve for capital
       expenditures, tenant improvements and leasing commissions.

CURRENT ECONOMIC CLIMATE

       Our short and long-term liquidity is significantly impacted by the
operating results of our properties, all of which are located in Southern
California. Our ability to lease available space and increase rates when leases
expire is largely dependent on the demand for office space in the markets where
our properties are located. National and local economic trends may affect demand
for our properties. The timing and extent of changes in the national and local
economy and their effects on our properties and results of operations are
difficult to accurately predict. Some sectors of the national and California
economy, particularly the sectors containing


                                       32
<PAGE>   33

technology and Internet companies, are reported to be experiencing slower
growth, reduced earnings or increased losses. Problems associated with
deregulation of the electric industry in California have resulted in
intermittent service interruptions and significantly higher costs in some areas
of the state. As of the date of this Form 10-K, we have not noted any material
trends or effects arising from these national and regional issues on our ability
to lease and renew available space, to increase rental rates as leases expire
and to collect amounts due from our tenants. It is possible, however, that these
national and regional issues may more directly affect us and our operating
results in the future, making it more difficult for us to lease and renew
available space, to increase or maintain rental rates as leases expire and to
collect amounts due from our tenants. See "Risk Factors -- Our operating
performance and property values will be affected by changes in the economic
climate in Southern California," -- "the financial condition and solvency of our
tenants may reduce our cash flow," and "- Rising energy costs and power outages
in California may have an adverse effect on our operations and revenue."

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
you, 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.

       Even though we currently have no such agreements, 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, 2000, a 1% increase in interest rates on our $253.4 million of floating rate
debt would decrease annual future earnings and cash flows by approximately $2.5
million and would not have an impact on the fair value of the floating rate
debt. A 1% decrease in interest rates on our $253.4 million of floating rate
debt would increase annual future earnings and cash flows by approximately $2.5
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. The weighted average
interest rate on our floating debt as of December 31, 2000 was 8.58%

       Our fixed rate debt totaled $924.4 million as of December 31, 2000 with a
weighted average interest rate of 8.02% and an unrealized loss of approximately
$25.9 million for a total fair value of approximately $898.5 million. A 1%
decrease in interest rates on our $924.4 million of fixed rate debt would
decrease its fair value by approximately $45.2 million and would not have an
impact on annual future earnings and cash flows. A 1% increase in interest rates
in our $924.4 million of fixed rate debt would increase its fair value by
approximately $45.2 million and would not have an impact of annual future
earnings and cash flows.

<PAGE>   34

       These amounts are determined by considering the impact of hypothetical
interest rates on our borrowing cost. These analyses do not consider the effects
of the reduced level of overall economic activity that could exist in that
environment. Further, in the event of a change of this magnitude, we would
consider taking actions to further mitigate our exposure to the change. Due to
the uncertainty of the specific actions that would be taken and their possible
effects, however, this sensitivity analysis assumes no changes in our capital
structure.

                                  RISK FACTORS

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

       Through 2005, 2,729 leases, including month-to-month leases comprising
73% of our leased net rentable square footage and 73% of our annualized base
rents at December 31, 2000 will expire as follows:

</TABLE>

       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 business 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 that are
unique to or particularly affect the Southern California economy and real estate
market, which may adversely affect our business.

       Competition affects occupancy levels rents and cost of land which could
adversely affect our revenues.

       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. Although ownership of these
competing properties is currently diversified among many different types, from
publicly traded companies and institutional investors to small enterprises and
individual owners, and no one or group of owners currently dominate or
significantly influence the market, consolidation of owners could create
efficiencies and marketing advantages for the consolidated group that could
adversely affect us. These competitive advantages, the number of competitors and
the number of competitive commercial properties in a particular area could have
a material adverse effect on the rents we can charge, our ability to lease space
in our existing properties or at newly acquired or developed properties and the
prices we have to pay for developable land.

       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
<PAGE>   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.

       Rising energy costs and power outages in California may have an adverse
effect on our operations and revenue.

       Problems associated with deregulation of the electric industry in
California have resulted in intermittent service interruptions and significantly
higher costs in some areas. Approximately 55% of our buildings and approximately
56% of the total net rentable square footage of our portfolio are located within
municipalities that either do not produce their own power or have not entered
into long term fixed price contracts. These properties may be subject to
intermittent service interruptions or significant rate increases from their
utility providers. The remaining portion of our portfolio is located in areas
that are not expected to be subject to intermittent electric service
interruptions and significant electric rate increases.

       Approximately 19% of our buildings and 15% of the total net rentable
square footage of our portfolio are subject to leases that require our tenants
to pay all utility costs. The remainder of our leases provide that tenants will
reimburse us for utility costs in excess of a base year amount. We estimate that
we will be able to recover approximately 90% of any utility cost increases from
our tenants.

       Although we have not experienced any material losses resulting from
electric deregulation, it is possible that some of our tenants will not fulfill
their lease obligations and reimburse us for their share of any significant
electric rate increases and that we will not be able to retain or replace our
tenants if energy problems in California continue.

       Increases in taxes and regulatory compliance costs may reduce our
revenue.

       Except for our triple net leases, we may not be able to pass all real
estate tax increases through to some of our tenants. 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, state
and local regulatory requirements, such as requirements of the Americans with
Disabilities Act, and state 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. 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 our
business.

       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 any agreements to do so, we may
participate with other entities in property ownership through joint ventures or
partnerships in the future. Depending on the characteristics and business
objectives of the joint venture or partnershiup, we may not have voting control
over the joint venture or partnership. 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.


                                       35
<PAGE>   36

       Neither our limited partnership agreement nor Arden Realty's governing
documents prevent us from participating in joint ventures with our affiliates.
Because a joint venture with an affiliate may not be negotiated in a traditional
arm's length transaction, terms of the joint venture may not be as favorable to
us as we could obtain if we entered into a joint venture with an outside third
party.

       We may not be able to integrate or finance our acquisitions.

       As we acquire additional properties, we will be subject to risks
associated with managing new properties, including building systems not
operating as expected, delay in or failure to lease vacant space and tenants
failing to renew leases as they expire. In addition, our ability to manage our
growth effectively will require us to successfully integrate our new
acquisitions into our existing accounting systems and property 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. Moreover, acquisition
costs of a property may exceed original estimates, possibly making the property
uneconomical.

       Our acquisitions and renovations may not perform as expected.

       Although we currently have no plans to significantly expand or renovate
our properties, we may do so in the future. Expansion and renovation projects
may inconvenience and displace existing tenants, require us to engage in time
consuming up-front planning and engineering activities and expend capital, and
require us to obtain 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.

       Our development activities may be more expensive than anticipated and may
not yield our anticipated results.

       We currently have three properties under development at the Howard Hughes
Center in Los Angeles, California. The estimated total costs for these three
properties is approximately $204.2 million. In addition, we have preliminary
architectural designs completed for additional build-to-suit buildings at the
Howard Hughes Center and have completed preliminary designs on a build-to-suit
office building at our Long Beach Airport Business Park, but do not intend to
commence construction on any of these projects until development plans and
budgets are finalized and build-to-suit tenant leases are signed with terms
allowing us to achieve yields commensurate with the project's development risk.
We also intend to review, from time to time, other opportunities for developing
and constructing office buildings and other commercial properties in accordance
with our development and underwriting policies.

       We expect to finance our development activities over the next 24 months
through net cash provided by operating activities, proceeds from asset sales or
proceeds from our lines of credit.

       Risks associated with our development 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 are not subject to any limit on the amount or percentage of our assets
that may be invested in any single property or any single geographic area.

       Our partnership agreement and other governing documents do not restrict
the amount or percentage of our assets that we may invest in a single property
or geographic area. All of our properties are currently in Southern California
and we have no immediate plans to invest outside of Southern California. This
lack of diversification in our investments makes us more highly susceptible to
changes affecting the Southern California economy and real estate markets or
damages from regional events such as earthquakes.

       We may not be able to expand into new markets successfully.

       While our business is currently limited 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 now and will continue to have a significant amount of debt. As of
December 31, 2000, we had total debt of approximately $1.2 billion, consisting
of approximately $576 million in secured debt and approximately $602 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.


                                       37
<PAGE>   38

       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. Neither our partnership nor Arden
Realty's charter or bylaws limit the amount or the percentage of indebtedness
that we may incur. We may borrow up to a maximum of $360 million under our three
lines of credit. In addition, we have the option to increase our $275 million
unsecured line of credit by $50 million. If we exercised the option, we would be
able to borrow up to $410 million under our three lines of credit. As of
December 31, 2000, we had the ability to borrow an additional approximately
$106.6 million under these three lines of credit. If new debt is added to our
current debt levels, the related risks that we now face could intensify and
could increase the risk of default on our indebtedness.

       Scheduled debt payments could adversely affect our financial condition.

       Our cash flow could be insufficient to meet required payments of
principal and interest when due. In addition, we may not be able to refinance
existing indebtedness, which in virtually all cases requires substantial
principal payments at maturity, and, if we can refinance, the terms of the
refinancing might not be as favorable as the terms of our existing indebtedness.
As of December 31, 2000, approximately $8.5 million of principal will be coming
due over the next twelve months. If principal payments 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 and continue to service and repay our debt obligations.

       Rises in interest rates could adversely affect our financial condition.

       An increase in prevailing interest rates would have an immediate effect
on the interest rates charged on our variable rate debt which rise and fall upon
changes in interest rates. At December 31, 2000, approximately 22% of our debt
was variable rate debt. Increases in interest rates would also impact the
refinancing of our fixed rate debt. If interest rates are higher when our fixed
debt becomes due, we may be forced to borrow at the higher rates. If prevailing
interest rates or other factors result in higher interest rates, the increased
interest expense would adversely affect our cash flow and our ability to 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. As of December 31, 2000, we were not a party to any such
agreements.

       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 $556.8
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 two or more mortgages are cross-defaulted, a default in one mortgage will
trigger a default in the other mortgages. The cross-defaults can give the lender
a number of remedies depending on the circumstances such as the right to
increase the interest rate, demand additional collateral, accelerate the
maturity date of the mortgages or foreclose on and sell the properties. To the
extent two or more mortgages are cross-collateralized, a default in one mortgage
will allow the mortgage lender to foreclose upon and sell the properties that
are not the primary collateral for the loan in default. Five additional
properties are subject to single property mortgages totaling approximately $19.3
million at December 31, 2000. If we are unable to meet our obligations under
these mortgages, we could be forced to pay higher interest rates or provide
additional collateral or the properties subject to the mortgages could be
foreclosed upon and sold, which could have a material adverse effect on us and
our ability to pay or refinance our debt obligations.

TAX RISKS

       Our partnership agreement 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, Arden Realty must distribute to its
stockholders at least 95% of its REIT taxable income (90% beginning January 1,
2001), excluding net capital gain, and to avoid federal income taxation, its
distributions must not be less than 100% of its REIT taxable income, including
capital gains. To avoid excise tax liability, Arden Realty's distributions to
its 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. Our partnership agreement generally requires us to distribute
substantially all of our available cash generated from operations each quarter
and make reasonable efforts to distribute to Arden Realty enough cash for it to
meet the 90% distribution requirement and to avoid any federal income or excise
tax liability. 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.

       We intend to qualify as a partnership, but we cannot guarantee that we
will qualify.

       We intend to qualify as a partnership for federal income tax purposes.
However, if we are a "publicly traded partnership," we will 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
we would meet this 90% test, but we cannot guarantee that it would. If we were
to be taxed as a corporation, we would incur substantial tax liabilities, Arden
Realty would fail to qualify as a REIT for federal income tax purposes and our
and Arden Realty's ability to raise additional capital could be significantly
impaired.

       We may suffer adverse tax consequences and be unable to attract capital
if Arden Realty fails to qualify as a REIT.

       We believe that since its taxable year ended December 31, 1996, Arden
Realty has been organized and operated, and intends to continue to operate, so
as to qualify for taxation as a REIT under the Internal Revenue Code. Although
we believe that Arden Realty has been and will continue to be organized and has
operated and will continue to operate so as to qualify for taxation as a REIT,
we cannot assure you that it has been or will continue to be organized or
operated in a manner so as to qualify or remain so qualified. Qualification as a
REIT involves the satisfaction of 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 Arden Realty, that holds its 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 Arden Realty's ability to operate as a
REIT. Arden Realty's qualification and taxation as a REIT depends on its 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 Arden Realty failed to qualify as a REIT in any taxable year, it would
be subject to federal income tax, including any applicable alternative minimum
tax, on its taxable income at regular corporate rates. Moreover, unless entitled
to relief under specific statutory provisions, it also would be disqualified as
a REIT for the four taxable years following the year during which qualification
was lost. If it were disqualified as a REIT, Arden Realty might cause us to
distribute adequate amounts so as to permit it to pay its tax liabilities. In
addition, Arden Realty's ability to raise additional capital for us could be
significantly impaired. This could reduce the funds we would have available to
service our debt.


                                       39
<PAGE>   40

       Even if Arden Realty qualifies for and maintains its REIT status, it will
be subject to certain federal, state and local taxes on its income and property.
For example, if Arden Realty has 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

       Our general partner may change policies without stockholder or partner
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 general partner.
Although Arden Realty has 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 Arden
Realty without a vote of its stockholders or approval by the limited partners.
In addition, Arden Realty 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 and results of operations.

       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.

       An earthquake could adversely affect our business.

       All of our properties are located in Southern California which is 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, 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.


                                       40
<PAGE>   41

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

       The environmental site assessments and investigations have identified a
total of 28 properties in our portfolio, representing approximately 26.7% of the
total net rentable square feet of the portfolio affected by environmental
concerns. These environmental concerns include properties that may be impacted
by known or suspected (a) contamination caused by third party sources or (b)
soil and/or groundwater contamination which has been or is being remediated, and
(c) those containing underground storage tanks, asbestos, or some known or
suspected amount of indoor air contaminants.

       Of these properties, one is believed to be affected by contamination
caused by third party sources and houses underground storage tanks, one contains
friable asbestos, 14 contain non-friable asbestos, nine house underground
storage tanks, and three contain known or suspected indoor air contaminants. The
property affected by contamination is affected primarily by petroleum and
solvent substances, and a third party has indemnified us for any and all
problems associated with this contamination. With regard to those properties
affected by asbestos, asbestos does not pose a health hazard if it is not
disturbed in such a way to cause an airborne release of asbestos. Asbestos is
friable when it can be crumbled, pulverized or reduced to powder by hand
pressure, and non-friable when hand pressure cannot release encapsulated
asbestos fibers. Friable asbestos is more likely to be released into the air
than no-friable asbestos. We manage all asbestos in ways that minimize its
potential to become airborne or otherwise threaten human health. Regarding
underground storage tanks, subsurface leakage of the materials contained within
the tank constitutes the primary risk posed by these devices. We comply with all
applicable laws, including double-wall construction, testing protocols,
placement of tanks within bermed areas, and the installation of leak and spill
detection equipment, to minimize the risks posed by underground storage tanks.

       The environmental site assessments and investigations have not,
however, revealed any environmental liability that we believe would have a
material adverse effect on our business, 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.

       We believe that our properties are in compliance in all material respects
with all federal, state and local laws 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. It is possible that future laws will impose material
environmental liabilities on us and that the current environmental condition of
our properties will 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.

                                                  REPORT OF INDEPENDENT AUDITORS

The Partners
Arden Realty Limited Partnership

       We have audited the accompanying consolidated balance sheets of Arden
Realty Limited Partnership as of December 31, 2000 and 1999 and the related
consolidated statements of income, partner's capital and cash flows for each of
the three years in the period ended December 31, 2000. These financial
statements are the responsibility of the management of Arden Realty Limited
Partnership. 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 Limited Partnership at December 31, 2000 and 1999 and the consolidated
results of its operations and its cash flows for each of the three years in the
period ended December 31, 2000, in conformity with accounting principles
generally accepted in the United States.

                        ARDEN REALTY LIMITED PARTNERSHIP

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. BUSINESS

       Description of Business

       The terms "us," "we" and "our" as used in these financial statements
refer to Arden Realty Limited Partnership. The term "Arden Realty" refers to
Arden Realty, Inc.

       Organization and Formation

       We are an operating partnership that owns, manages, leases, develops,
renovates and acquires commercial properties located in Southern California.
Arden Realty, a real estate investment trust, or REIT, is our sole general
partner and, as of December 31, 2000 and 1999, owned 96.7% of our common
partnership units, or common OP Units. Arden Realty conducts substantially all
of its operations through us and our subsidiaries. Commencing with its taxable
year ended December 31, 1996, Arden Realty has operated and qualified as a REIT
for federal income tax purposes.

       Arden Realty conducts substantially all of its operations through us. As
of December 31, 2000 our portfolio consisted of 142 primarily suburban office
properties containing approximately 18.7 million net rentable square feet and
three properties with approximately 725,000 square feet under development. As of
December 31, 2000, our properties were approximately 95.5% leased.

       Arden Realty's interest in us entitles it to share in cash distributions
from, and in our profits and losses in proportion to its percentage ownership.
Certain individuals and entities own our remaining common OP Units, including
Messrs. Ziman and Coleman, our Chairman and Chief Executive Officer and our
President and Chief Operating Officer, respectively, together with other
entities and persons who were issued common OP Units in connection with our
acquisition of specific properties previously owned by those entities and
persons. Each limited partner holding common OP Units is entitled to cause us to
redeem the limited partner's common OP Units for cash. Arden Realty, however,
may, instead of paying cash, elect to exchange those common OP Units for shares
of its common stock on a one-for-one basis, subject to certain limitations. With
each redemption or exchange of common OP Units, Arden Realty's percentage
interest in us will increase.

       As our sole general partner, Arden Realty generally has the exclusive
power under our partnership agreement to manage us and conduct our business,
subject to limited exceptions. Arden Realty's board of directors manages our
affairs. We cannot be terminated until the year 2096 without the approval of a
majority of our partners or in connection with the sale of all or substantially
all of our assets, a business combination, a judicial decree or the redemption
of all the OP Units held by our limited partners.

       We are a Maryland limited partnership. Arden Realty is a Maryland
corporation. Arden Realty's common stock is listed on the New York Stock
Exchange under the symbol "ARI."

2. BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

       Basis of Presentation

       The accompanying consolidated financial statements include our accounts
and our subsidiaries. All significant intercompany balances and transactions
have been eliminated in consolidation.

       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


                                      F-6

operations of these properties could be affected by the economic conditions in
this region.

       Segment Information

       We view our operations as principally one segment, namely the operation
of commercial real estate located in Southern California, and the financial
information disclosed herein represents all of the financial information related
to this principal operating segment.

       Commercial Properties

       Our properties are stated at depreciated 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,
are less than its book value. Properties held for disposition are carried at the
lower of depreciated cost or fair value. Based on our assessment, no write-downs
to estimated fair value were necessary as of December 31, 2000 and 1999,
respectively.

       Repair and maintenance costs are charged to expenses as incurred and
significant replacements and betterments are capitalized. Repairs and
maintenance costs include all costs that do not extend the useful life of an
asset or increase its operating efficiency. Significant replacements and
betterments represent costs that extend an asset's useful life or increase its
operating efficiency.

       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.

       Costs associated with leasing properties are capitalized and amortized to
expense on a straight-line basis over the related lease term.

       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, 2000 and 1999 primarily consists of $13.9
million and $13.7 million, respectively, in cash deposits as required by certain
of our mortgage loans payable and $5.4 million and $4.8 million, respectively,
in impound accounts for real estate taxes and insurance, as required by certain
of our mortgage loans payable.

       Prepaid Financing Costs

       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

       Our taxable income is reportable by our partners on their separate income
tax returns. Accordingly, no provision has been made for income taxes in the
accompanying consolidated statements of operations.

       Fair Value of Financial Instruments

       Our disclosures of estimated fair value of financial instruments at
December 31, 2000 were determined using available market information and
appropriate valuation methodologies. Considerable judgment is 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 and
other financial instruments are carried at amounts that reasonably approximate
their fair value amounts.

       The estimated fair value of our notes payable is as follows (in
thousands):

       The estimated fair value is based on interest rates available at each of
the dates presented for issuance of debt with similar terms and remaining
maturities. The estimated fair value amounts of our notes payable above are not
necessarily indicative of the amounts that we could realize in a current market
exchange. The unrealized gains in our notes payable are presented for disclosure
purposes and are not reflected in our balance sheets or results of operations.

       New Accounting Standards

       In June 1998, June 1999 and June 2000, respectively, the Financial
Accounting Standards Board issued Statement No. 133, "Accounting for Derivative
Instruments and Hedging Activities," Statement No. 137, "Accounting for
Derivative Instruments and Hedging Activities - Deferral of the Effective Date
of Statement No. 133," and Statement No. 138, "Accounting for Certain Derivative
Instruments and Certain Hedging Activities - an Amendment of Statement No. 133."
These statements outline the accounting treatment for all derivative activity.
In October 2000, the SEC issued "Frequently Asked Questions on Staff Accounting
Bulletin No. 101 on Revenue Recognition." This document formalizes the position
of the SEC staff regarding key topics about income recognition. We adopted SAB
101 on October 1, 2000 and its adoption did not impact our financial results. We
adopted Statement No. 133 on January 1, 2001 and do not expect adoption to have
a significant effect on our consolidated results of operations or financial
position.

       Reclassifications

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

 3. COMMERCIAL PROPERTIES

       Acquisitions

       We did not acquire any properties in 2000.

       Dispositions

       On October 13, 2000, we sold a 76,000 net rentable square foot retail
property located in Thousand Oaks, California, for approximately $12.0 million
and recorded a gain of approximately $2.1 million.

       Capitalized Interest

       We capitalize interest and taxes related to buildings under construction
and renovation to the extent those assets qualify for capitalization.

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 8.84%
at December 31, 2000.

(6)    This line of credit has a one-year extension option.

(7)    Requires semi-annual interest payments only, with principal balance due

       Unsecured Lines of Credit

       On May 3, 2000, we extended our unsecured line of credit with a group of
banks led by Wells Fargo. The extended line of credit provides for borrowings up
to $275 million with an option to increase the amount to $325 million and bears
interest at a rate ranging between LIBOR plus 1.15% and LIBOR plus 1.80%
(including an annual facility fee ranging from .20% to .40% based on the
aggregate amount of the facility)depending on our unsecured debt rating. In
addition, as long as we maintain an unsecured debt rating of BBB-/Baa3 or
better, the agreement contains a competitive bid option, whereby the lenders on
this of line of credit may bid on the interest rate to be charged for up to
$137.5 million of the unsecured line of credit. Under certain circumstances, we
also have the option to convert the interest rate on this line of credit to the
prime rate plus 0.5%. This line of credit matures in April 2003. As of December
31, 2000, there was approximately $172.4 million outstanding on this line of
credit and approximately $102.6 million was available for additional borrowings.

       This line of credit is subject to customary conditions to borrowing;
contains representations, warranties


                                      F-10
<PAGE>   61
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.
Proceeds from this line of credit have been used to provide funds for tenant
improvements and capital expenditures and to provide for working capital and
other purposes.

       In July 2000, we closed on a $75 million unsecured line of credit with
Lehman Brothers. Borrowings on this new line of credit bear interest at a rate
ranging between LIBOR plus 1.05% and LIBOR plus 1.70%, depending on our
unsecured debt rating. We also have the option to convert the interest rate to
the prime rate plus 0.5%. This line of credit matures in July 2002 with an
option to extend the maturity date for one year. Proceeds from this line of
credit have been used to reduce the outstanding balance under our $275 million
line of credit. As of December 31, 2000, there was approximately $75 million
outstanding on this line of credit.

       In August 2000, we extended our an unsecured line of credit with a total
commitment of $10 million from City National Bank to August 2001. This line of
credit accrues interest at the City National Bank Prime Rate less 0.875%. As
of December 31, 2000, there was $6 million outstanding on this line of credit
and $4 million was available for additional borrowing. Proceeds from this line
of credit have been used, among other things, to provide funds for tenants
improvements and capital expenditures and provide for working capital and other
purposes.

       Unsecured Senior Notes

       On March 17, 2000, we issued $250 million of senior unsecured notes in
two tranches. One tranche was for $200 million at an interest rate of 8.875% due
in March 2005 and the other tranche was for $50 million at an interest rate of
9.150% due in March 2010. These notes are our 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 and a mortgage loan and to reduce the outstanding
balance 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 Rule 144A under the Securities Act. We subsequently filed a
registration statement that became effective on May 10, 2000 and all privately
placed notes were exchanged for notes registered under the Securities Act.

       On November 20, 2000, we completed a private placement of $100 million
8.50% senior notes due November 2010, with interest payable semi-annually on
November 15 and may 15 of each year. We used the net proceeds from this private
placement to reduce the outstanding balance on one of our unsecured lines of
credit and to repay a construction loan related to our development of the 6060
Center Drive Project. These senior unsecured notes were issued in a private
placement in reliance of upon an exemption from registration provided by Rule
144A under the Securities Act. We subsequently filed a registration statement
that became effective on March 29, 2001 and are currently exchanging these
privately placed notes for registered notes. We expect to complete this exchange
by April 26, 2001.

(1)    Consists primarily of $75.0 million outstanding on our Lehman Brothers
       line of credit which has a one year extension.

(2)    Consists primarily of $172.4 million outstanding on our Wells Fargo line
       of credit.


       6. PARTNERS' CAPITAL

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

       During 2000, Arden Realty issued a total of 373,000 restricted stock
awards to several key executive officers. The restriction on these shares
prohibits the sale or transfer of such shares and lapses equally over four years
for 100,000 shares and over five years for 273,000 shares. We have recorded a
deferred compensation charge of approximately $9.5 million, based on the market
value of these shares on the date of award, in the accompanying consolidated
statement of partners' capital and will amortize such charge on a
straight-line basis over the restriction period for each award. In 2000, we
recorded $586,000 in non-cash compensation expense related to these restricted
stock awards.

       On September 7, 1999, we completed a $50 million private placement of 2
million 8-5/8% Series B Cumulative Redeemable Preferred 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 8-5/8% Series B
Cumulative Redeemable Preferred Stock of Arden Realty, 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 outstanding common OP Units held by limited partners are initially
recorded at fair value and subsequently adjusted based on fair value at the
balance sheet date as measured by the closing price of Arden Realty's common
stock at that date multiplied by the total number of common OP Units held by
limited partners.

       In January 2001, we made a quarterly distribution of $0.465 per common OP
Unit.

       7. COMMITMENTS AND CONTINGENCIES

       Capital Commitments

       As of December 31, 2000, we had approximately $14.1 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.


                                      F-12
<PAGE>   63

       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 General Partner for Common OP Units

       In August 1998, we issued 85,106 shares of common OP Units to Arden
Realty, related to the issuance of 42,553 shares of Arden Realty's 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 were recourse and secured by the shares of
common stock issued to the executive officers.

       Mr. Andrew J. Sobel resigned as Executive Vice President and Director of
Property Operations effective February 18, 2000. At the time of his resignation,
Mr. Sobel surrendered the common stock underlying his promissory note 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. In July 2000, Mr. Sobel returned to Arden Realty as Executive
Vice President -- Strategic Planning and Operations, terminating the consulting
and non-competition agreement described above, and is in the process of
finalizing a new employment agreement with Arden Realty addressing, among other
things, the promissory note.

       Ms. Diana Laing resigned as Executive Vice President and Chief Financial
Officer effective July 1, 2000. At the time of her resignation, Ms. Laing
surrendered stock options valued at approximately $59,000 as well as the 42,553
shares of Arden Realty's common stock underlying her promissory note. The value
of the options and shares surrendered by Ms. Laing equaled the unpaid principal
and interest of her promissory note.

10. 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 APB 25, 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.

       Arden Realty established a stock option plan for the purpose of
attracting and retaining executive officers, directors and other key employees.
As of December 31, 2000, 6,500,000 of Arden Realty's 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 such
options and all options were granted at exercise prices equal to the market
prices at the date of the grant.

       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 2000, 1999 and 1998, respectively: risk-free interest rate of
6.13%, 6.67% and 5.68%; dividend yield of 7.75%, 5.79% and 7.25% and a
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, 2000, 1999 and 1998

11. 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 $517,000 in 2000,
$385,000 in 1999 and $187,000 in 1998. Plan participants are immediately vested
in their contributions and are vested equally over four years in matching
contributions by us.
