PART I

ITEM 1. BUSINESS

The Company
Kilroy Realty Corporation (the "Company") owns, operates, develops, and
acquires Class A suburban office and industrial real estate in key suburban
submarkets, primarily in Southern California, that the Company believes have
strategic advantages and strong barriers to entry. The Company, which
operates, qualifies, and intends to continue to qualify as a self-administered
and self-managed real estate investment trust ("REIT") for federal and state
income tax purposes, was incorporated in September 1996 and commenced
operations upon the completion of its initial public offering in January 1997.
The Company is the successor to the real estate business of Kilroy Industries,
a California corporation ("KI"), and certain of its affiliated corporations,
partnerships and trusts (collectively, the "Kilroy Group").

As of December 31, 2000, the Company's portfolio of stabilized operating
properties was comprised of 83 office buildings (the "Office Properties") and
78 industrial buildings (the "Industrial Properties," and together with the
Office Properties, the "Properties") which encompassed an aggregate of
approximately 6.6 million and 5.8 million rentable square feet, respectively.
The Properties include 21 properties that the Company developed and then
stabilized during 2000 and 1999 encompassing an aggregate of approximately
809,000 and 1.2 million rentable square feet, respectively. As of December 31,
2000, the Office Properties were approximately 96.2% leased to 302 tenants and
the Industrial Properties were 97.8% leased to 220 tenants. All but ten of the
Properties are located in Southern California.

The Company's stabilized portfolio excludes projects currently under
construction or in pre-development and "lease-up" properties. The Company
defines "lease-up" properties as properties recently developed by the Company
that have not yet reached 95% occupancy. The Company had one lease-up property
at December 31, 2000, encompassing an aggregate of approximately 197,300
rentable square feet, which stabilized on January 15, 2001. As of December 31,
2000, the Company had 11 office properties under construction or committed for
construction which when completed are expected to encompass an aggregate of
approximately 964,400 rentable square feet at a total estimated investment of
approximately $232 million. In addition, as of December 31, 2000, the Company
owned approximately 67 acres of undeveloped land upon which the Company
currently expects to develop an aggregate of approximately 1.3 million
rentable square feet of office space within the next three to four years. All
of the Company's development projects and undeveloped land parcels are located
in Southern California.

The Company owns its interests in all of the Properties through Kilroy
Realty, L.P. (the "Operating Partnership") and Kilroy Realty Finance
Partnership, L.P., a Delaware limited partnership (the "Finance Partnership").
The Company conducts substantially all of its activities through the Operating
Partnership in which, as of December 31, 2000, it owned an approximate 87.6%
general partnership interest. The remaining 12.4% limited partnership interest
in the Operating Partnership was owned by certain of the Company's executive
officers and directors, certain of their affiliates, and other outside
investors. As the sole general partner of the Operating Partnership, the
Company has control over the management of the Operating Partnership, which
owns 137 of the Company's 161 Properties. The remaining properties, other than
six buildings which are owned by the Operating Partnership through KR-Carmel
Partners and KR-Gateway Partners, (together, the "Development LLCs"), in which
the Operating Partnership owned a 50% managing interest at December 31, 2000,
are owned by the Finance Partnership. Kilroy Realty Finance, Inc., a wholly-
owned subsidiary of the Company, is the sole general partner of the Finance
Partnership and owns a 1% general partnership interest. The Operating
Partnership owns the remaining 99% limited partnership interest of the Finance
Partnership. Unless otherwise indicated, all references to the Company include
the Operating Partnership, the Finance Partnership, the Development LLCs and
all wholly-owned subsidiaries and controlled entities.

As of December 31, 2000 the Operating Partnership owned 100% of the non-
voting preferred stock and a 95% economic interest in Kilroy Services, Inc.
("KSI"), an unconsolidated subsidiary of the Company. All of

1


the voting interest was held by John B. Kilroy, Sr., the Chairman of the
Company's Board of Directors, and John B. Kilroy, Jr., the Company's President
and Chief Executive Officer. Prior to December 31, 2000, the operating results
of the development services business conducted by KSI were accounted for under
the equity method of accounting. On January 1, 2001, KSI was merged into a
newly formed entity, Kilroy Services, LLC ("KSLLC"). In connection with the
merger, the interests held by Messers Kilroy were liquidated and KSLLC became
a wholly owned subsidiary of the Company. KSLLC will be consolidated for
financial reporting purposes beginning January 1, 2001.

Current Year Highlights

The Company continued to successfully attain its primary business objective
of maximizing growth in Funds From Operations, as defined by the National
Association of Real Estate Investment Trusts, ("NAREIT") through accomplishing
the following during the year ended December 31, 2000:

. Execution of lease agreements on approximately 2.0 million rentable
square feet of office and industrial space, including both renewals and
turnovers, at average rental rates 23.7% above 1999 average rental rates
on a basis consistent with generally accepted accounting principles
("GAAP").

. Achievement of 96.9% average occupancy for the Company's stabilized
portfolio for the year ended December 31, 2000. Occupancy was 97.0% at
December 31, 2000.

. Completion of nine office buildings encompassing approximately 1.0
million rentable square feet at a total estimated investment of $203
million. These properties were approximately 98% occupied at December
31, 2000.

. Continued improvement of the quality of the Company's portfolio through
reinvesting approximately $114 million of capital obtained from the sale
of mature, non-strategic assets, into brand new, state-of-the-market
assets that the Company is developing in attractive coastal submarkets
in Southern California.

. Acquisition of approximately 20 acres of undeveloped land and the
initiation of actions to acquire an office complex containing
approximately 366,000 rentable square feet. In January 2001, the Company
completed the acquisition of this office complex and began the
redevelopment of one of the buildings.

. Execution of seven new secured and unsecured debt financings that
provided the Company with approximately $239 million of additional
future borrowing capacity. The Company's total debt as a percentage of
total market capitalization was approximately 41.9% at December 31,
2000.

. Execution of interest rate swap and interest rate cap agreements that
resulted in approximately 82.1% of the Company's total debt being fixed
or capped at December 31, 2000.

Business and Growth Strategies

Growth Strategies. The Company believes that a number of factors will
enable it to continue to achieve its objectives of long-term sustainable
growth in net operating income, defined as operating revenues less property
and related expenses (property expenses, real estate taxes and ground leases)
before depreciation, and Funds From Operations, as defined by NAREIT, as well
as maximization of long-term stockholder value including: (i) the opportunity
to lease available space at attractive rental rates because of high demand and
frictional vacancy levels in the Southern California submarkets in which most
of the properties are located; (ii) the quality and location of the Company's
properties; (iii) the Company's existing substantial development pipeline as
established over the past several years; (iv) the Company's access to
development and leasing opportunities as a result of its extensive experience
and significant working relationships with major Southern California corporate
tenants, municipalities and landowners given the Company's over 50-year
presence in the Southern California market; and (v) the Company's ability to
efficiently manage its assets as a low cost provider of commercial real estate
due to its core capabilities in all aspects of real estate ownership including
property management, leasing, marketing, financing, accounting, legal,
construction management and new development. Management believes that the
Company is well positioned to capitalize on existing opportunities because of
its extensive experience in its submarkets, its seasoned management team and
its proven ability to develop, lease, acquire and efficiently manage office
and industrial properties.


2


Operating Strategies. The Company focuses on enhancing growth in net
operating income and Funds From Operations from its properties by: (i)
maintaining higher than average occupancy rates; (ii) maximizing cash flow
from the properties through active leasing, early renewals, increasing
contractual base rent to current market levels as leases expire and effective
property management; (iii) structuring leases to maximize returns and internal
growth and underwriting leases to manage portfolio credit risk; (iv) managing
operating expenses through the efficient use of internal management, leasing,
marketing, financing, accounting and construction management functions; (v)
maintaining and developing long-term relationships with a diverse tenant
group; (vi) managing the buildings in a way that offers the maximum degree of
utility and operational efficiency to tenants; (vii) continuing to emphasize
capital improvements to enhance the properties' competitive advantages in
their respective markets and improve the efficiency of building systems; and
(viii) attracting and retaining motivated employees by providing financial and
other incentives to meet the Company's operating and financial goals.

Development Strategies. The Company and its predecessors have developed
office and industrial properties, including high technology facilities,
primarily located in Southern California, for its own portfolio and for third
parties, since 1947. Over the past several years, the Company has established
a substantial development pipeline in its two target market regions, Los
Angeles and San Diego Counties. The Company's, in-process, committed and
future development pipeline (including projects held through joint venture
arrangements) can support future development of approximately an aggregate of
2.3 million rentable square feet of office space at a total budgeted cost of
approximately $486 million within the next three to four years. The Company's
strategy with respect to development is as follows: (i) reinvest capital from
strategic dispositions of mature, non-strategic assets into new, state-of-the-
market development assets with higher cash flows and rates of return; (ii)
maintain a disciplined approach to development by focusing on pre-leasing,
phasing and cost control; (iii) continue to expand the Company's build-to-suit
program where it develops properties committed to be leased by specific
tenants since such strategy provides for lower risk development; (iv) pursue
redevelopment opportunities in land constrained markets since such efforts
achieve similar returns to new development with reduced entitlement risk and
shorter construction periods; and (v) to be the premier low-cost provider of
two four-story campus style office buildings in Southern California.

During 2000 and 1999, the Company completed an aggregate of 19 buildings
encompassing an aggregate of approximately 1.9 million rentable square feet at
an aggregate cost of approximately $305 million. As of December 31, 2000, the
Company had 11 office buildings under construction or committed for
construction which when completed are expected to encompass an aggregate of
approximately 964,400 rentable square feet at a total estimated investment of
approximately $232 million. The Company may engage in the additional
development of office and/or industrial properties, primarily in Southern
California, when market conditions support a favorable risk-adjusted return on
such development. The Company's activities with third-party owners in Southern
California are expected to give the Company further access to development
opportunities. There can be no assurance, however, that the Company will be
able to successfully develop any of the properties or that it will have access
to additional development opportunities.

Financing Strategies. The Company's financing policies and objectives are
determined by the Company's Board of Directors. The Company's goal is to limit
its dependence on leverage and maintain a conservative ratio of debt to total
market capitalization (total debt of the Company as a percentage of the market
value of issued and outstanding shares of common stock, including interests
exchangeable therefor, plus total debt). This ratio may be increased or
decreased without the consent of the Company's stockholders and the Company's
organizational documents do not limit the amount of indebtedness that the
Company may incur. At December 31, 2000, total debt constituted approximately
41.9% of the total market capitalization of the Company. The Company's funding
strategies are as follows: (i) maintain financial flexibility and the ability
to access a variety of capital sources; (ii) maintain a staggered debt
maturity schedule to limit risk exposure to any particular point in the
capital and credit market cycles; (iii) complete financing deals in advance of
the need for capital; and (iv) manage interest rate exposure.

3


The Company intends to utilize one or more sources of capital for future
growth, which may include undistributed cash flow, borrowings under the
Company's unsecured credit facility (the "Credit Facility"), the issuance of
debt or equity securities and other bank and/or institutional borrowings.
There can be no assurance, however, that the Company will be able to obtain
capital on terms favorable to the Company.

Significant Tenants

As of March 22, 2001, the Company's ten largest office tenants represented
approximately 28.9% of total annual base rental revenues, defined as
annualized monthly contractual rents from existing tenants at December 31,
2000 determined on a straight-line basis over the term of the related lease in
accordance with GAAP, and its ten largest industrial tenants represented
approximately 9.3% of total annual base rental revenues. Of this amount, its
largest tenant, The Boeing Company, currently leases an aggregate of
approximately 776,900 rentable square feet of office space under twelve
separate leases, representing approximately 9.2% of the Company's total annual
base rental revenues at December 31, 2000. The base periods for 14.9% of The
Boeing Company leases expire over the next 18 months. The base periods for the
remaining leases for The Boeing Company expire during the period from January
2004 through August 2005.

The Company's five largest office tenants, based on annualized base rental
revenues, include: The Boeing Company; Peregrine Systems, Inc.; Epson America,
Inc.; Epicor Software Corporation; and Intuit, Inc. The Company's five largest
industrial tenants, based on annualized base rental revenues, include:
Celestica California, Inc.; Qwest Communications Corporation; Mattel, Inc.;
Abovenet Communications, Inc.; and OmniPak (d.b.a. Raven Industries); (See
Item 2: Properties--Tenant Information for further discussion on the Company's
tenant base.)

Employees

As of March 22, 2001, the Company, through the Operating Partnership and
KSI employed 143 persons. The Company, the Operating Partnership and KSI
believe that relations with their employees are good.

Government Regulations

Many laws and governmental regulations are applicable to the Company's
properties and changes in these laws and regulations, or their interpretation
by agencies and the courts, occur frequently.

Costs of Compliance with the Americans with Disabilities Act. Under the
Americans with Disabilities Act of 1990 (the "ADA"), all public accommodations
must meet federal requirements related to access and use by disabled persons.
Although management believes that its properties substantially comply with
present requirements of the ADA, none of its properties have been audited and
investigations of all of its properties have not been conducted to determine
compliance. The Company may incur additional costs of complying with the ADA.
Additional federal, state and local laws also may require modifications to the
Company's properties, or restrict its ability to renovate the properties.
Management cannot predict the ultimate amount of the cost of compliance with
the ADA or other legislation. If the Company incurs substantial costs to
comply with the ADA and any other legislation, its financial condition,
results of operations, cash flow, quoted per share trading price of its common
stock and ability to pay distributions to stockholders could be adversely
affected.

Environmental Matters

Costs related to government regulation and private
litigation. Environmental laws and regulations hold the Company liable for the
costs of removal or remediation of certain hazardous or toxic substances
released on its properties. These laws could impose liability without regard
to whether the Company is responsible for, or even knew of, the presence or
release of the hazardous materials. Government investigations and remediation
actions may have substantial costs and the presence of hazardous substances on
a property could result in personal injury or similar claims by private
plaintiffs. For instance, if asbestos-containing materials and other

4


hazardous or toxic substances were found on the Company's properties, third
parties might seek recovery from the Company for personal injuries associated
with the existence of those substances. As of December 31, 2000, 30 of the
Company's properties contained asbestos-containing materials. Various laws
also impose liability on persons who arrange for the disposal or treatment of
hazardous or toxic substances for the cost of removal or remediation of
hazardous substances at the disposal or treatment facility. These laws often
impose liability whether or not the person arranging for the disposal ever
owned or operated the disposal facility. As the owner and operator of its
properties, the Company may be considered to have arranged for the disposal or
treatment of hazardous or toxic substances.

Use of hazardous materials by some of our tenants. Some of the Company's
tenants routinely handle hazardous substances and wastes on its properties as
part of their routine operations. Environmental laws and regulations subject
these tenants, and potentially the Company, to liability resulting from such
activities. The Company requires its tenants, in their leases, to comply with
these environmental laws and regulations and to indemnify the Company for any
related liabilities. As of December 31, 2000, less than 5% of the Company's
tenants routinely handled hazardous substances and/or wastes on the Company's
properties as part of their routine operations. These tenants were primarily
involved in the light industrial and warehouse business and more specifically
the light electronics assembly business. Management does not believe that
these activities by its tenants will have any material adverse effect on the
Company's operations. Furthermore, management is unaware of any material
noncompliance, liability or claim relating to hazardous or toxic substances or
petroleum products in connection with any of the Company's properties.

Existing conditions at some of our properties. Independent environmental
consultants have conducted Phase I or similar environmental site assessments
on all of the Company's properties. The Company generally obtains these
assessments prior to the acquisition of a property and may later update them
as required for subsequent financing of the property or as requested by
tenants. Site assessments generally include a historical review, a public
records review, an investigation of the surveyed site and surrounding
properties, and the issuance of a written report. These assessments do not
generally include soil samplings or subsurface investigations. The Company's
site assessments revealed that 30 of its properties contain asbestos-
containing materials and that historical operations at or near some of its
properties, including the operation of underground storage tanks, may have
caused soil or groundwater contamination. Prior owners of the affected
properties conducted clean-up of contamination in the soils on the properties
and management does not believe that further clean-up of the soils is
required. None of the Company's site assessments revealed any other
environmental liability that management believes would have a material adverse
effect on the Company's business, assets, or results of operations. Management
is not aware of any such condition, liability, or concern by any other means
that would give rise to material environmental liability. However, the
assessments may have failed to reveal all environmental conditions,
liabilities, or compliance concerns; there may be material environmental
conditions, liabilities, or compliance concerns that arose at a property after
the review was completed; future laws, ordinances or regulations may impose
material additional environmental liability; and current environmental
conditions at the Company's properties may be affected in the future by
tenants, third parties, or the condition of land or operations near its
properties (such as the presence of underground storage tanks). The Company
cannot give assurance that the costs of future environmental compliance will
not affect its ability to make distributions to stockholders.

Environmental insurance coverage limits. The Company carries what
management believes to be sufficient environmental insurance to cover any
potential liability for soil and groundwater contamination at the affected
sites identified in the environmental site assessments. However, management
cannot provide any assurance that the Company's insurance coverage will be
sufficient or that its liability, if any, will not have a material adverse
effect on the Company's financial condition, results of its operations, cash
flow, quoted per share trading price of its common stock and ability to pay
distributions to stockholders.

Other federal, state and local regulations. The Company's properties are
subject to various federal, state and local regulatory requirements, such as
state and local fire and life safety requirements. If the Company failed to
comply with these various requirements, it might incur governmental fines or
private damage awards.

5


Management believes that the Company's properties are currently in material
compliance with all of these regulatory requirements. However, management does
not know whether existing requirements will change or whether future
requirements will require the Company to make significant unanticipated
expenditures that will adversely affect its ability to make distributions to
its stockholders. The City of Los Angeles adopted regulations relating to the
repair of welded steel moment frames located in certain areas damaged as a
result of the January 17, 1994 Northridge earthquake in Southern California.
Currently, these regulations apply to only one of the Company's properties
representing approximately 78,000 rentable square feet. Management believes
that this property complies with these regulations. Management does not know,
however, whether other regulatory agencies will adopt similar regulations or
whether the Company will acquire additional properties which may be subject to
these or similar regulations. Management believes, based in part on
engineering reports which are generally obtained at the time the properties
are acquired, that all of its properties comply in all material respects with
the current regulations. However, if the Company were required to make
significant expenditures under applicable regulations, its financial
condition, results of operations, cash flow, quoted per share trading price of
its common stock and ability to pay distributions to stockholders could be
adversely affected.

Business Risks

This document contains certain forward-looking statements (as such term is
defined in Section 27A of the Securities Act of 1933, as amended (the "1933
Act"), and Section 21E of the Exchange Act of 1934, as amended (the "1934
Act")) pertaining to, among other things, the Company's future results of
operations, cash available for distribution, property acquisitions, lease
renewals, increases in base rent, development activities, sources of growth,
planned development and expansion of owned or leased property, capital
requirements, compliance with contractual obligations and federal, state and
local regulations, conditions of properties, environmental findings and
general business, industry and economic conditions applicable to the Company.
These statements are based largely on the Company's current expectations and
are subject to a number of risks and uncertainties. Actual results could
differ materially from these forward-looking statements. Factors that can
cause actual results to differ materially include, but are not limited to,
those discussed below. Readers are cautioned not to place undue reliance on
these forward-looking statements, which speak only as of the date hereof. The
following factors should be considered in addition to the other information
contained herein in evaluating the Company and its business:

Most of the Company's properties depend upon the Southern California
economy. As of December 31, 2000, 89.7% of the aggregate square footage of the
Company's stabilized portfolio and 92.2% of the Company's annualized base
rent, excluding expense reimbursements and rental abatements, came from
properties located in Southern California. The Company's ability to make
expected distributions to stockholders depends on its ability to generate
Funds From Operations in excess of scheduled principal payments on debt,
payments on the preferred limited partnership units issued by the Operating
Partnership, and capital expenditure requirements. Events and conditions
applicable to owners and operators of real property that are beyond the
Company's control may decrease funds available for distribution and the value
of the Company's properties. These events include: local oversupply or
reduction in demand of office, industrial or other commercial space; inability
to collect rent from tenants; vacancies or inability to rent spaces on
favorable terms; inability to finance property development and acquisitions on
favorable terms; increased operating costs, including insurance premiums,
utilities, and real estate taxes; costs of complying with changes in
governmental regulations; the relative illiquidity of real estate investments;
changing submarket demographics and property damage resulting from seismic
activity. The geographical concentration of the Company's properties may
expose it to greater economic risks than if it owned properties in several
geographic regions. Any adverse economic or real estate developments in the
Southern California region could adversely impact the Company's financial
condition, results from operations and cash flows.

Increasing utility costs and power outages in California may have an
adverse effect on the Company's operating results. Uncertainties and problems
associated with the deregulation of the electric industry in California have
resulted in higher utility costs and intermittent service interruptions in
some areas of the state.

6


However, approximately 75% (based on net rentable square footage) of the
Company's current leases require tenants to pay utility costs directly;
therefore, eliminating the Company's exposure. The remaining 25% of the
Company's leases provide that the tenants reimburse the Company for utility
costs in excess of a base year amount.

Although the Company has not experienced any material trends or effects
arising from this regional issue, it is possible that some of its tenants may
not fulfill their lease obligations or reimburse the Company for their share
of any significant utility increases. In addition it is possible that the
Company may not be able to retain or replace its tenants if energy problems in
California continue or worsen. As a result the Company's financial condition,
results of operations, and cash flows may be adversely affected.

The Company's debt level reduces cash available for distribution and may
expose the Company to the risk of default under its debt obligations. Payments
of principal and interest on borrowings may leave the Company with
insufficient cash resources to operate its properties or to pay distributions
necessary to maintain its REIT qualification. The Company's level of debt and
the limitations imposed by its debt agreements may have important consequences
on the Company, including the following: cash flow may be insufficient to meet
required principal and interest payments; the Company may be unable to
refinance its indebtedness at maturity or the refinancing terms may be less
favorable than the terms of its original indebtedness; the Company may be
forced to dispose of one or more of its properties, possibly on
disadvantageous terms; the Company may default on its obligations and the
lenders or mortgagees may foreclose on the properties that secure the loans
and receive an assignment of rents and leases; the Company's default under one
mortgage loan with cross default provisions could result in a default on other
indebtedness; and the Company may be unable to complete its development plans
or pursue other development opportunities. If one or more of these events were
to occur, the Company's financial position, results of operations, cash flow,
quoted per share trading price of its common stock and ability to pay
distributions to stockholders could be adversely affected. In addition,
foreclosures could create taxable income without accompanying cash proceeds, a
circumstance which could hinder the Company's ability to meet the strict REIT
distribution requirements imposed by the Internal Revenue Code of 1986, as
amended. As of December 31, 2000, the Company had approximately $724 million
aggregate principal amount of indebtedness, $5.7 million of which is due prior
to December 31, 2001. The Company's total debt represented 41.9% of its total
market capitalization at December 31, 2000.

The Company faces significant competition which may decrease the occupancy
and rental rates of its properties. The Company competes with several
developers, owners and operators of office, industrial and other commercial
real estate, many of which have higher vacancy rates. Substantially all of the
Company's properties are located in areas with similar properties as its
competitors. For instance, the occupancy rate for the Company's Long Beach
Airport office property portfolio at December 31, 2000 was 94.1%, in
comparison to 90.9%, for the Long Beach Airport office submarket in total. The
Company believes that its lower vacancy rates means that, on average, its
competitors have more space currently available for lease than the Company. As
a result, the Company's competitors have an incentive to decrease rental rates
until their available space is leased. If the Company's competitors offer
space at rental rates below current market rates, the Company may be pressured
to reduce its rental rates below those currently charged in order to retain
tenants when its tenant leases expire. As a result, the Company's financial
condition, results of operations and cash flows may be adversely affected.

Potential losses may not be covered by insurance. The Company carries
comprehensive liability, fire, extended coverage and rental loss insurance
covering all of its properties. Management believes the policy specifications
and insured limits are appropriate given the relative risk of loss, the cost
of the coverage and industry practice. The Company does not carry insurance
for generally uninsurable losses such as loss from riots or acts of God. Some
of the Company's policies, like those covering losses due to floods, are
subject to limitations involving large deductibles or co-payments and policy
limits. In addition, the Company carries earthquake insurance on properties
located in areas known to be subject to earthquakes in an amount and with

7


deductions which management believes are commercially reasonable. As of
December 31, 2000, 80 of the Office Properties aggregating 6.1 million square
feet (representing approximately 49.0% of the Company's stabilized portfolio
based on aggregate square footage and approximately 70.4% based on annualized
base rent) were located in areas known to be subject to earthquakes. As of
December 31, 2000, 74 of the Company's Industrial Properties aggregating 5.4
million square feet (representing approximately 43.4% of the Company's
stabilized portfolio based on aggregate square footage and approximately 23.5%
based on annualized base rent) were located in areas known to be subject to
earthquakes. While the Company presently carries earthquake insurance on these
properties, the amount of its earthquake insurance coverage may not be
sufficient to cover losses from earthquakes. In addition, the Company may
discontinue earthquake insurance on some or all of its properties in the
future if the cost of premiums for earthquake insurance exceeds the value of
the coverage discounted for the risk of loss. If the Company experiences a
loss which is uninsured or which exceeds policy limits, it could lose the
capital invested in the damaged properties as well as the anticipated future
revenue from those properties. In addition, if the damaged properties are
subject to recourse indebtedness, the Company would continue to be liable for
the indebtedness, even if the properties were unrepairable.

The Company may be unable to successfully complete and operate developed
properties. There are several risks associated with property development. The
Company may be unable to obtain construction financing on favorable terms or
may be unable to obtain permanent financing at all or on advantageous terms if
development projects are financed through construction loans. In addition, the
Company may not complete development projects on schedule or within budgeted
amounts; the Company may encounter delays or refusals in obtaining all
necessary zoning, land use, building, occupancy, and other required
governmental permits and authorizations; the Company may expend funds on and
devote management's time to projects which the Company may not complete. Also,
the Company may lease the developed properties at below expected rental rates.
For example, during the fourth quarter of 1998, the Company withdrew its
participation from a master planned commercial development prior to the
commencement of construction. Also, during the third quarter of 2000, the
Company delayed commencement of construction on one of its projects by four
months. The project was an assemblage in an urban infill location that
required the relocation of some existing businesses. The Company encountered
delays when one of the existing tenants experienced difficulty in relocating
as a result of the high leasing demand and tight supply constraints in that
sub-market.

If one or more of these events were to occur in connection with projects
currently under development, the Company's financial position, results of
operations, cash flow, quoted per share trading price of its common stock and
ability to pay distributions to stockholders could be adversely affected.
While the Company primarily develops office and industrial properties in
Southern California markets, it may in the future develop properties for
retail or other use and expand its business to other geographic regions where
it expects the development of property to result in favorable risk-adjusted
returns on its investment. Presently, the Company does not possess the same
level of familiarity with development of other property types or outside
markets which could adversely affect its ability to develop properties or to
achieve expected performance.

The Company may be unable to complete acquisitions and successfully operate
acquired properties. The Company may acquire office and industrial properties
when strategic opportunities exist. The Company's ability to acquire
properties on favorable terms and successfully operate them is subject to the
following risks: the potential inability to acquire a desired property because
of competition from other real estate investors with significant capital,
including both publicly traded REITs and institutional investment funds; even
if the Company enters into agreements for the acquisition of office and
industrial properties, these agreements are subject to customary conditions to
closing, including completion of due diligence investigations to management's
satisfaction; the Company may be unable to finance the acquisition on
favorable terms; the Company may spend more than budgeted amounts to make
necessary improvements or renovations to acquired properties; and the Company
may lease the acquired properties at below expected rental rates. If the
Company cannot finance property acquisitions on favorable terms or operate
acquired properties to meet financial expectations, its financial position,
results of operations, cash flow, quoted per share trading price of its common
stock and ability to pay distributions to stockholders could be adversely
affected.

8


The Company could default on leases for land on which some of its
properties are located. The Company owns ten office buildings located on
various parcels, each of which the Company leases on a long-term basis. If the
Company defaults under the terms of any particular lease, it may lose the
property subject to the lease. The Company may not be able to renegotiate a
new lease on favorable terms, if at all, upon expiration of the lease and all
of its options. The loss of these properties or an increase of rental expense
would have an adverse effect on the Company's financial position, results of
operations, cash flow, quoted per share trading price of its common stock and
ability to pay distributions to stockholders. The Company has approximately
1.3 million aggregate rentable square feet of rental space located on these
leased parcels at December 31, 2000. The leases for the land under the SeaTac
Office Center, including renewal options, expire in 2062. The lease for the
land under 9455 Towne Center in San Diego expires in October 2043. The primary
lease for the land under 12312 West Olympic Boulevard in Santa Monica expires
in January 2065 with a smaller secondary lease expiring in September 2011. The
leases for the land under the Kilroy Airport Center, Long Beach expire in
2035. Subsequent to December 31, 2000, the Company acquired the fee interest
in the land at 9455 Towne Center Drive in San Diego, California and the ground
lease was terminated.

The Company depends on significant tenants. As of March 22, 2001, the
Company's ten largest office tenants represented approximately 28.9% of total
annualized base rent at December 31, 2000 and its ten largest industrial
tenants represented approximately 9.3% of total annualized base rent at
December 31, 2000. Of this amount, its largest tenant, The Boeing Company,
currently leases approximately 776,900 rentable square feet of office space,
representing approximately 9.2% of the Company's total annual base rental
revenues. See further discussion on the composition of the Company's tenants
by industry at "Item 2--Properties." The Company's revenue and cash available
for distribution to stockholders would be disproportionately and materially
adversely affected if any of its significant tenants were to become bankrupt
or insolvent, or suffer a downturn in their business, or fail to renew their
leases at all or on terms less favorable to the Company than their current
terms.

Downturns in tenants' businesses may reduce the Company's cash flow. As of
December 31, 2000, the Company derived approximately 96.6% of its revenues
from rental income and tenant reimbursements. A tenant may experience a
downturn in its business, which may weaken its financial condition and result
in its failure to make timely rental payments. In the event of default by a
tenant, the Company may experience delays in enforcing its rights as landlord
and may incur substantial costs in protecting its investment. The bankruptcy
or insolvency of a major tenant also may adversely affect the income produced
by the Company's properties. If any tenant becomes a debtor in a case under
the Bankruptcy Code, the Company cannot evict the tenant solely because of the
bankruptcy. On the other hand, the bankruptcy court might authorize the tenant
to reject and terminate its lease. The Company's claim against the tenant for
unpaid, future rent would be subject to a statutory cap that might be
substantially less than the remaining rent actually owed under the lease. Even
so, the Company's claim for unpaid rent would likely not be paid in full. This
shortfall could adversely affect the Company's cash flow and its ability to
make distributions to stockholders. Although the Company has not experienced
material losses from tenant bankruptcies, the Company may experience losses as
a result of tenants filing for bankruptcy protection in the future.

Subsequent to December 31, 2000, one of the Company's tenants, eToys, Inc.
("eToys"), defaulted under its lease with the Company covering 151,000
rentable square feet of office space. In connection with the execution of the
lease, eToys had provided the Company with $15.0 million in letters of credit,
which were established pursuant to the lease to provide credit support to
eToys lease obligations. In January 2001, the Company exercised its rights
under the lease and the letters of credit and drew down $15.0 million.
Subsequent to the Company drawing the $15.0 million, eToys filed for
protection under Chapter 11 of the federal bankruptcy laws. As discussed in
the preceding paragraph, the Company may experience losses in connection with
the bankruptcy of eToys, including losses resulting from costs, delays and
rental rate decreases the Company may experience in its ability to release the
space, and any losses resulting from the bankruptcy could be material to the
Company's consolidated results from operations.

The Company may be unable to renew leases or re-let space as leases
expire. As of December 31, 2000, leases representing approximately 14.2% and
6.1% of the square footage of the Company's properties will expire

9


in 2001 and 2002, respectively. Above market rental rates on some of the
Company's properties may force it to renew or re-lease some expiring leases at
lower rates. While the Company believes that the average rental rates for most
of its properties are below currently quoted market rates in each of its
submarkets, the Company cannot give any assurance that leases will be renewed
or that its properties will be re-leased at rental rates equal to or above the
current rental rates. If the rental rates for the Company's properties
decrease, existing tenants do not renew their leases, or the Company does not
re-lease a significant portion of its available space, its financial position,
results of operations, cash flow, quoted per share trading price of its common
stock and ability to pay distributions to its stockholders would be adversely
affected.

Real estate assets are illiquid and the Company may not be able to sell its
properties when it desires. The Company's investments in its properties are
relatively illiquid which limits the Company's ability to sell its properties
quickly in response to changes in economic or other conditions. In addition,
the Internal Revenue Code of 1986, as amended, generally imposes a 100%
prohibited transaction tax on profits the Company derives from sales of
properties held primarily for sale to customers in the ordinary course of
business, which could effect the Company's ability to sell properties. These
restrictions on the Company' ability to sell its properties could have an
adverse effect on its financial position, results from operations, cash flow,
quoted per share trading price of its common stock and ability to repay
indebtedness and to pay distributions to stockholders.

Common limited partners of the Operating Partnership have limited approval
rights which may prevent the Company from completing a change of control
transaction which may be in the best interests of stockholders. The Company
may not withdraw from the Operating Partnership or transfer its general
partnership interest or admit another general partner without the approval of
a majority of the common limited partnership unitholders except in the case of
a "termination transaction" which requires the approval of 60% of the common
limited partnership unitholders, which include the Company because of its
percentage holding of the common limited partnership units it holds in its
capacity as general partner. The right of common limited partners to vote on
these transactions could limit the Company's ability to complete a change of
control transaction that might otherwise be in the best interest of its
stockholders.

Limited partners of the Operating Partnership must approve the dissolution
of the Operating Partnership and the disposition of properties they
contributed. For as long as limited partners own at least 5% of all of the
common units of the Operating Partnership, the Company must obtain the
approval of limited partners holding a majority of the common units before it
may dissolve the partnership or sell the property located at 2260 East
Imperial Highway at Kilroy Airport Center in El Segundo prior to January 31,
2004. As of December 31, 2000, limited partners owned approximately 12.4% of
the outstanding interests in the Operating Partnership. In addition, the
Company may not sell 11 of its properties prior to October 31, 2002 without
the consent of the limited partners that contributed the properties to the
Operating Partnership, except in connection with the sale or transfer of all
or substantially all of its assets or those of the Operating Partnership or in
connection with a transaction which does not cause the limited partners that
contributed the property to recognize taxable income. In addition, the
Operating Partnership agreed to use commercially reasonable efforts to
minimize the tax consequences to common limited partners resulting from the
repayment, refinancing, replacement or restructuring of debt, or any sale,
exchange or other disposition of any of its other assets. The exercise of one
or more of these approval rights by the limited partners could delay or
prevent the Company from completing a transaction which may be in the best
interest of its stockholders.

The Company's Chairman of the Board of Directors and its President and Chief
Executive Officer each have potential conflicts of interest with the Company.

The Company's Chairman of the Board of Directors and its President and
Chief Executive Officer each have substantial influence over the Company's
affairs. John B. Kilroy, Sr. and John B. Kilroy, Jr., the Company's Chairman
of the Board of Directors and President and Chief Executive Officer,
respectively, together hold two of the six seats on the Company's Board of
Directors. They also beneficially own common limited partnership units
exchangeable for an aggregate of 1,795,572 shares of the Company's common
stock and currently vested options to purchase an aggregate of 433,334 shares
of common stock, representing a total of approximately 8.4%

10


of the total outstanding shares of common stock as of December 31, 2000.
Pursuant to the Company's charter no other stockholder may own, actually or
constructively, more than 7.0% of the Company's common stock. The Board of
Directors has waived the ownership limits with respect to John B. Kilroy, Sr.,
John B., Kilroy, Jr., members of their families and some affiliated entities.
Consequently, Messrs. Kilroy have substantial influence on the Company and
could exercise their influence in a manner that is not in the best interest of
the Company's stockholders. Also, they may, in the future, have a substantial
influence on the outcome of any matters submitted to the Company's
stockholders for approval.

There are limits on the ownership of the Company's capital stock which
limit the opportunities for a change of control at a premium to existing
stockholders. Provisions of the Maryland General Corporation Law, the
Company's charter, the Company's bylaws, and the Operating Partnership's
partnership agreement may delay, defer, or prevent a change in control over
the Company or the removal of existing management. Any of these actions might
prevent the stockholders from receiving a premium for their shares of stock
over the then prevailing market prices.

The Internal Revenue Code sets forth stringent ownership limits on the
Company as a result of its decision to be taxed as a REIT, including: no more
than 50% in value of the Company's capital stock may be owned, actually or
constructively, by five or fewer individuals, including some entities, during
the last half of a taxable year; subject to exceptions, the Company's common
stock shares must be held by a minimum of 100 persons for at least 335 days of
a 12-month taxable year, or a proportionate part of a short taxable year; and
if the Company, or any entity which owns 10% or more of its capital stock,
actually or constructively owns 10% or more of one of the Company's tenants,
or a tenant of any partnership in which the Company is a partner, then any
rents that the Company receives from that tenant in question will not be
qualifying income for purposes of the Internal Revenue Code's REIT gross
income tests regardless of whether the Company receives the rents directly or
through a partnership.

The Company's charter establishes clear ownership limits to protect its
REIT status. No single stockholder may own, either actually or constructively,
more than 7.0% of the Company's common stock outstanding. Similarly, no single
holder of the Company's Series A Preferred Stock, Series C Preferred Stock and
Series D Preferred Stock may actually or constructively own any class or
series of its preferred stock, so that their total capital stock ownership
would exceed 7.0% by value of the Company's total capital stock, and no single
holder of Series B Preferred Stock, if issued, may actually or constructively
own more than 7.0% of the Company's Series B Preferred Stock.

The Board of Directors may waive the ownership limits if it is satisfied
that the excess ownership would not jeopardize the Company's REIT status and
if it believes that the waiver would be in the Company's best interests. The
Board of Directors has waived the ownership limits with respect to John B.
Kilroy, Sr., John B. Kilroy, Jr., members of their families and some
affiliated entities. These named individuals and entities may own either
actually or constructively, in the aggregate, up to 21% of the outstanding
common stock.

If anyone acquires shares in excess of any ownership limits, the transfer
to the transferee will be void with respect to these excess shares; the excess
shares will be automatically transferred from the transferee or owner to a
trust for the benefit of a qualified charitable organization, the purported
transferee or owner will have no right to vote those excess shares, and the
purported transferee or owner will have no right to receive dividends or other
distributions from these excess shares.

The Company's charter contains provisions that may delay, defer, or prevent a
change of control transaction.

The Company's Board of Directors is divided into classes that serve
staggered terms. The Company's Board of Directors is divided into three
classes with staggered terms. The staggered terms for directors may reduce the
possibility of a tender offer or an attempt to complete a change of control
transaction even if a tender offer or a change in control was in the Company's
stockholders' interest.

11


The Company could issue preferred stock without stockholder approval. The
Company's charter authorizes its Board of Directors to issue up to 30,000,000
shares of preferred stock, including convertible preferred stock, without
stockholder approval. The Board of Directors may establish the preferences,
rights and other terms, including the right to vote and the right to convert
into common stock any shares issued. The issuance of preferred stock could
delay or prevent a tender offer or a change of control even if a tender offer
or a change of control was in the Company's stockholders' interest. The
Operating Partnership has issued 1,500,000 Series A Cumulative Redeemable
Preferred units which in the future may be exchanged one-for-one into shares
of 8.075% Series A Cumulative Redeemable Preferred stock, 700,000 Series C
Cumulative Redeemable Preferred units which in the future may be exchanged one
for one into shares of 9.375% Series C Cumulative Redeemable Preferred stock,
and 900,000 Series D Cumulative Redeemable Preferred units which in the future
may be exchanged one for one into shares of 9.250% Series D Cumulative
Redeemable Preferred stock. In addition, the Company has designated and
authorized the issuance of up to 400,000 shares of Series B Junior
Participating Preferred stock. However, no shares of preferred stock of any
series are currently issued or outstanding.

The Company has a stockholders' rights plan. In October 1998, the Company's
Board of Directors adopted a stockholders' rights plan and declared a
distribution of one preferred share purchase right for each outstanding share
of common stock. The rights have anti-takeover effects and would cause
substantial dilution to a person or group that attempts to acquire the Company
on terms that the Company's Board of Directors does not approve. The Company
may redeem the shares for $.01 per right, prior to the time that a person or
group has acquired beneficial ownership of 15% or more of its common stock.
Therefore, the rights should not interfere with any merger or business
combination approved by the Company's Board of Directors.

The staggered terms for directors, the future issuance of additional common
or preferred stock and the Company's stockholders rights plan may: delay or
prevent a change of control, even if a change of control might be beneficial
to the Company's stockholders; deter tender offers that may be beneficial to
the Company's stockholders; or limit stockholders' opportunity to receive a
potential premium for their shares if an investor attempted to gain shares
beyond the Company's ownership limits or otherwise to effect a change of
control.

Loss of the Company's REIT status would have significant adverse
consequences to it and the value of the Company's stock. The Company currently
operates and has operated since 1997 in a manner that is intended to allow it
to qualify as a REIT for federal income tax purposes under the Internal
Revenue Code. If the Company were to lose its REIT status, it would face
serious tax consequences that would substantially reduce the funds available
for distribution to stockholders for each of the years involved because: the
Company would not be allowed a deduction for distributions to stockholders in
computing its taxable income and would be subject to federal income tax at
regular corporate rates; the Company could be subject to the federal
alternative minimum tax and possibly increased state and local taxes; and
unless entitled to relief under statutory provisions, the Company could not
elect to be subject to tax as a REIT for four taxable years following the year
during which it was disqualified. In addition, if the Company fails to qualify
as a REIT, it will not be required to make distributions to stockholders and
all distributions to stockholders will be subject to tax as ordinary income to
the extent of the Company's current and accumulated earnings and profits. As a
result of all these factors, the Company's failure to qualify as a REIT also
could impair its ability to expand its business and raise capital, and would
adversely affect the value of the Company's common stock.

Qualification as a REIT involves the application of highly technical and
complex Internal Revenue Code provisions for which there are only limited
judicial and administrative interpretations. 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
that holds its assets through a partnership. The determination of various
factual matters and circumstances not entirely within the Company's control
may affect its ability to qualify as a REIT. For example, in order to qualify
as a REIT, at least 95% of the Company's gross income in any year must be
derived from qualifying sources. Also, the Company must make distributions to
stockholders aggregating annually at least 95% of its net taxable income (90%
beginning January 1, 2001), excluding capital gains. In addition, legislation,
new regulations, administrative interpretations or court decisions may
adversely affect the

12


Company's investors or the Company's ability to qualify as a REIT for tax
purposes. Although management believes that the Company is organized and
operates in a manner so as to qualify as a REIT, no assurance can be given
that the Company has been or will continue to be organized or be able to
operate in a manner so as to qualify or remain qualified as a REIT for tax
purposes.

To maintain its REIT status, the Company may be forced to borrow funds on a
short-term basis during unfavorable market conditions. To qualify as a REIT,
the Company generally must distribute to its stockholders at least 95% (90%
beginning January 1, 2001) of its net taxable income each year, excluding
capital gains, and the Company is subject to regular corporate income taxes to
the extent that it distributes less than 100% of its net taxable income each
year. In addition, the Company will be subject to a 4% nondeductible excise
tax on the amount, if any, by which certain distributions paid in any calendar
year are less than the sum of 85% of its ordinary income, 95% of its capital
gain net income and 100% of its undistributed income from prior years. In
order to maintain its REIT status, the Company may need to borrow funds on a
short term basis to meet the REIT distribution requirements even if the then
prevailing market conditions are not favorable for these borrowings. These
short-term borrowing needs could result from differences in timing between the
actual receipt of income and inclusion of income for federal income tax
purposes, or the effect of non-deductible capital expenditures, the creation
of reserves or required debt or amortization payments.

The Company's growth depends on external sources of capital which are
outside of the Company's control. The Company is required under the Internal
Revenue Code to distribute at least 95% of its taxable income (90% beginning
January 1, 2001), determined without regard to the dividends-paid deduction
and excluding any net capital gain. Because of this distribution requirement,
it may not be able to fund future capital needs, including any necessary
development financing, from operating cash flow. Consequently, management
relies on third-party sources of capital to fund the Company's capital needs.
The Company may not be able to obtain the financing on favorable terms or at
all. Any additional debt the Company incurs will increase its leverage. Access
to third-party sources of capital depends, in part, on: general market
conditions; the market's perception of the Company's growth potential; the
Company's current and expected future earnings; the Company's cash
distributions; and the market price per share of the Company's common stock.
If the Company cannot obtain capital from third-party sources, it may not be
able to acquire properties when strategic opportunities exist or make the cash
distributions to stockholders necessary to maintain its qualification as a
REIT.

The Company's Board of Directors may change investment and financing policies
without stockholder approval and become more highly leveraged which may
increase the Company's risk of default under its debt obligations.

The Company is not limited in its ability to incur debt. The Company's
Board of Directors adopted a policy of limiting indebtedness to approximately
50% of the Company's total market capitalization. Total market capitalization
is the market value of the Company's capital stock, including interests and
units exchangeable for shares of capital stock, plus total debt. However, the
Company's organizational documents do not limit the amount or percentage of
indebtedness, funded or otherwise, that it may incur. The Company's Board of
Directors may alter or eliminate management's current policy on borrowing at
any time without stockholder approval. If this policy changed, the Company
could become more highly leveraged which would result in an increase in its
debt service and which could adversely affect cash flow and the ability to
make expected distributions to stockholders. Higher leverage also increases
the risk of default on the Company's obligations.

The Company may issue additional shares of capital stock without
stockholder approval that may dilute shareholder investment. The Company may
issue shares of its common stock, preferred stock or other equity or debt
securities without stockholder approval. Similarly, the Company may cause the
Operating Partnership to offer its common or preferred units for contributions
of cash or property without approval by the limited partners of the Operating
Partnership or the Company's stockholders. Existing stockholders have no
preemptive rights to acquire any of these securities, and any issuance of
equity securities under these circumstances may dilute a stockholder's
investment.

13


The Company may invest in securities related to real estate which could
adversely affect its ability to make distributions to stockholders. The
Company may purchase securities issued by entities which own real estate and
may, in the future, also invest in mortgages. In general, investments in
mortgages include several risks, including: borrowers may fail to make debt
service payments or pay the principal when due; the value of the mortgaged
property may be less than the principal amount of the mortgage note securing
the property; and interest rates payable on the mortgages may be lower than
the Company's cost for the funds used to acquire these mortgages. Owning these
securities may not entitle the Company to control the ownership, operation and
management of the underlying real estate. In addition, the Company may have no
control over the distributions with respect to these securities, which could
adversely affect its ability to make distributions to stockholders.

Sales of a substantial number of shares of common stock, or the perception
that this could occur, could result in decreasing the market price per share
for the Company's common stock. Management cannot predict whether future
issuances of shares of the Company's common stock or the availability of
shares for resale in the open market will result in decreasing the market
price per share of its common stock.

As of December 31, 2000, 26,475,470 shares of the Company's common stock
were issued and outstanding and the Company had reserved for future issuance
the following shares of common stock: 3,748,545 shares issuable upon the
exchange, at the Company's option, of common units issued in connection with
the formation of the Operating Partnership and in connection with property
acquisitions; 2,704,930 shares issuable under the Company's 1997 Stock Option
and Incentive Plan; and 1,000,000 shares issuable under the Company's Dividend
Reinvestment and Direct Stock Purchase Plan. Of the 26,475,470 shares of
common stock presently outstanding, all but 195,000 shares may be freely
traded in the public market by persons other than the Company's affiliates. In
addition, the Company has filed or has agreed to file registration statements
covering all of the shares of common stock reserved for future issuance.
Consequently, if and when the shares are issued, they may be freely traded in
the public markets.

ITEM 2. PROPERTIES

General

As of December 31, 2000, the Company's portfolio of stabilized operating
properties was comprised of 83 Office Properties and 78 Industrial Properties
which encompassed an aggregate of approximately 6.6 million and 5.8 million
rentable square feet, respectively. The Properties include 21 properties that
the Company developed and then stabilized during 2000 and 1999 encompassing an
aggregate of approximately 809,000 and 1.2 million rentable square feet,
respectively. As of December 31, 2000, the Office Properties were
approximately 96.2% leased to 302 tenants and the Industrial Properties were
97.8% leased to 220 tenants. All but ten of the Properties are located in
Southern California.

The Company's stabilized portfolio excludes projects currently under
construction or in pre-development and "lease-up" properties. The Company
defines "lease-up" properties as properties recently developed by the Company
that have not yet reached 95% occupancy. The Company had one lease-up property
at December 31, 2000, encompassing an aggregate of 197,300 rentable square
feet, which stabilized on January 15, 2001. As of December 31, 2000, the
Company had 11 office properties under construction or committed for
construction which when completed are expected to encompass an aggregate of
approximately 964,400 rentable square feet at a total estimated investment of
approximately $232 million. All of the Company's development projects are
located in Southern California.

In general, the Office Properties are leased to tenants on a full service
gross basis and the Industrial Properties are leased to tenants on a triple
net basis. Under a full service lease, the landlord is obligated to pay the
tenant's proportionate share of taxes, insurance and operating expenses up to
the amount incurred during the tenant's first year of occupancy ("Base Year")
or a negotiated amount approximating the tenant's pro rata share of real
estate taxes, insurance and operating expenses ("Expense Stop"). The tenant
pays its pro-rata share of increases in expenses above the Base Year or
Expense Stop. Under a triple net lease, tenants pay their proportionate share
of real estate taxes, operating costs and utility costs.

The Company believes that all of its properties are well maintained and,
based on engineering reports obtained within the last five years, do not
require significant capital improvements. As of December 31, 2000, the Company
managed all of its 83 Office Properties and 76 of its 78 Industrial Properties
through internal property managers.

15


The Office and Industrial Properties

The following table sets forth certain information relating to each of the
Office and Industrial Properties owned as of December 31, 2000. The Company
(through the Operating Partnership and the Finance Partnership) owns a 100%
interest in all of the Office and Industrial Properties, except for the six

(1) Includes tenants only. Excludes leases for amenity, retail, parking and
month-to-month tenants. Some tenants have multiple leases.

(2) Based on total leased square footage for the respective portfolios as of
December 31, 2000 unless a lease for a replacement tenant had been
executed on or before January 1, 2001.

Secured Debt

At December 31, 2000, the Operating Partnership had 14 secured mortgage and
construction loans outstanding, representing aggregate indebtedness of
approximately $433 million, which were secured by certain of the Properties
and development projects (the "Secured Obligations"). See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Liquidity and Capital Resources" and Note 6 to the Company's consolidated
financial statements included herewith. Management believes that as of
December 31, 2000, the value of the properties securing the respective Secured
Obligations in each case exceeded the principal amount of the outstanding
obligation.

ITEM 3. LEGAL PROCEEDINGS

Neither the Company nor any of the Company's properties are presently
subject to any material litigation nor, to the Company's knowledge, is any
material litigation threatened against any of them which if determined
unfavorably to the Company would have a material adverse effect on the
Company's cash flows, financial condition or results of operations. The
Company is party to litigation arising in the ordinary course of business,
none of which if determined unfavorably to the Company is expected to have a
material adverse effect on the Company's cash flows, financial condition or
results of operations.

The Company pays distributions to common stockholders on or about the 17th
day of each January, April, July and October at the discretion of the Board of
Directors. Distribution amounts depend on the Company's Funds From Operations,
financial condition and capital requirements, the annual distribution
requirements under the REIT provisions of the Internal Revenue Code of 1986,
as amended (the "Code"), and such other factors as the Board of Directors
deems relevant.

During 2000, the Company issued 481,290 shares of common stock upon the
conversion of 481,290 common limited partnership units of the Operating
Partnership by limited partners. The issuances of the common shares on a one-
for-one basis were made pursuant to the terms set forth in the partnership
agreement of the Operating Partnership. The shares of common stock were issued
in transactions, not requiring registration under federal securities laws
pursuant to Section 4(2) of the Securities Act of 1933.

On October 13, 2000, the Operating Partnership issued 1,133 common limited
partnership units of the Operating Partnership, valued by the Company at
approximately $30,000 based upon the closing share price of the Company's
common stock as reported on the NYSE at the time of the respective
transactions, to Kilroy Airport Imperial Co. ("KAICO"), a partnership owned by
John B. Kilroy, Sr., the Company's Chairman of the Board of Directors, John B.
Kilroy, Jr. the Company's President and Chief Executive Officer, and certain
other Kilroy family members, in connection with the acquisition of the 25%
tenancy-in-common interest in the KAICO complex (see Note 13 to the Company's
consolidated financial statements). The common limited partnership units were
issued in reliance upon an exemption from registration provided by Regulation
D under the Securities Act as a transaction by an issuer not involving a
public offering. These units may be redeemed at the option of the Company for
cash or shares of the Company's common stock.

(1) As defined by the National Association of Real Estate Investment Trusts
("NAREIT"), "Funds From Operations" represents net income (loss) before
minority interest of common unitholders (computed in accordance with
GAAP), excluding gains (or losses) from debt restructuring and sales of
property, plus real estate related depreciation and amortization
(excluding amortization of deferred financing costs and depreciation of
non-real estate assets) and after adjustments for unconsolidated
partnerships and joint ventures. Non-cash adjustments to arrive at Funds
From Operations were as follows: in all periods, depreciation and
amortization; in 1996, gains on extinguishment of debt; and in 2000, 1999,
1998 and 1997 non-cash amortization of restricted stock grants. Further,
in 1996, non-recurring items (option buy-out cost) were excluded.
Management considers Funds From Operations an appropriate measure of
performance of an equity REIT because it is predicated on cash flow
analyses. The Company computes Funds From Operations in accordance with
standards established by the Board of Governors of NAREIT in its March
1995 White Paper as clarified by the November 1999 NAREIT National policy
bulletin which became effective on January 1, 2000, which may differ from
the methodology for calculating Funds From Operations utilized by other
equity REITs and, accordingly, may not be comparable to Funds From
Operations reported by such other REITs. Further, Funds From Operations
does not represent amounts available for management's discretionary use
because of needed capital reinvestment or expansion, debt service
obligations, or other commitments and uncertainties. See the notes to the
financial statements of the Company. Funds From Operations should not be
considered as an alternative to net income (loss) (computed in accordance
with GAAP) as an indicator of the properties' financial performance or to
cash flow from operating activities (computed in accordance with GAAP) as
a measure or indicator of the properties' liquidity, nor is it indicative
of funds available to fund the properties' cash needs, including the
Company's ability to pay dividends or make distributions.

(2) Funds From Operations for 1997 is derived from the results of operations
of Kilroy Realty Corporation for the period February 1, 1997 to December
31, 1997.

(3) Cash flow for 1997 represents the cash flow of the Kilroy Group for the
period January 1, 1997 to January 31, 1997 and Kilroy Realty Corporation
for the period February 1, 1997 to December 31, 1997.

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

The following discussion relates to the consolidated financial statements
of the Company and should be read in conjunction with the financial statements
and notes thereto appearing elsewhere in this report. Statements contained in
this "Management's Discussion and Analysis of Financial Condition and Results
of Operations" that are not historical facts may be forward-looking
statements. Such statements are subject to certain risks and uncertainties,
which could cause actual results to differ materially from those projected.
Some of the enclosed information presented is forward-looking in nature,
including information concerning development timing and investment amounts.
Although the information is based on the Company's current expectations,
actual results could vary from expectations stated here. Numerous factors will
affect the Company's actual results, some of which are beyond its control.
These include the timing and strength of regional economic growth, the

Overview and Background

The Company, which owns, develops, operates, and acquires office and
industrial real estate, primarily in Southern California, commenced operations
upon the completion of its initial public offering in January 1997 and
operates as a self-administered REIT. The Company owns its interests in all of
its properties through the Operating Partnership and the Finance Partnership
and conducts substantially all of its operations through the Operating
Partnership. The Company owned an 87.6% and 86.8% general partnership interest
in the Operating Partnership as of December 31, 2000 and 1999, respectively.
The Finance Partnership is a wholly-owned subsidiary of the Company.

The Company's revenue is derived primarily from rental income, including
tenant reimbursements. The Company's revenue growth in 2000 was due primarily
to operating results from $327 million of development projects completed and
added to the Company's portfolio of stabilized properties in 1999 and 2000 and
was also due to a 7.1% increase in net operating income from the Company's
"Core Portfolio". The Company defines its "Core Portfolio" as stabilized
properties owned at January 1, 1999 and still owned at December 31, 2000.
Management believes that the most significant part of the Company's revenue
growth within the next two to three years will come from its substantial
development pipeline of approximately 1.3 million rentable square feet of
office space to be developed over the next three to four years. Management
also believes that continued success of the real estate market in the
Company's principal markets will result in strong demand for office and
industrial space. Consequently, management currently expects that the
Company's revenue in the next one to two years will also grow as a result of
re-leasing, at generally higher lease rates, approximately 1.3 million square
feet of office space and 1.1 million square feet of industrial space currently
subject to leases expiring during the next two years.

Factors Which May Affect Future Results of Operations

As 89.7% of the total net rentable square footage of the Company's
stabilized portfolio is located in California, the Company's operating results
are and will continue to be affected by uncertainties and problems associated
with the deregulation of the electric industry in California. Such
deregulation has resulted in higher utility costs in some areas of the state
and intermittent service interruptions. As of the date of this report, the
Company has not experienced any material trends or effects arising from this
regional issue. Approximately 75% (based on net rentable square footage) of
the Company's current leases require tenants to pay utility costs

28


directly; therefore, eliminating the Company's exposure. The remaining 25% of
the Company's leases provide that the tenants reimburse the Company for utility
costs in excess of a base year amount. See "Risk factors--Increasing utility
costs and power outages in California may have an adverse effect on the
Company's operating results."

Results of Operations

During the year ended December 31, 2000, the Company completed the
development of nine office buildings encompassing an aggregate of approximately
$1.0 million rentable square feet. During the year ended December 31, 1999, the
Company completed the development of six office and four industrial buildings
encompassing an aggregate of approximately 472,200 and 390,200 rentable square
feet, respectively. All of the aforementioned development projects completed by
the Company during 2000 and 1999 were included in the Company's portfolio of
stabilized operating properties at December 31, 2000 with the exception of one
property which became stabilized on January 15, 2001. The Company's stabilized
portfolio consists of all of the Company's Office and Industrial Properties,
excluding projects currently under construction or in pre-development and
properties developed by the Company that have not reached 95.0% occupancy
("lease-up" properties). At December 31, 2000, the Company had eleven office
buildings under construction or committed for construction which when completed
are expected to encompass an aggregate of approximately 964,400 rentable square
feet.

During the year ended December 31, 2000, the Company disposed of nine office
and nine industrial buildings encompassing 286,700 and 669,800 aggregate
rentable square feet, respectively, for an aggregate sales price of $113.6
million at a net gain of approximately $11.3 million. During the year ended
December 31, 1999, the Company acquired three office buildings encompassing an
aggregate of approximately 176,900 rentable square feet, for an aggregate
acquisition cost of $30.6 million, and disposed of five office and five
industrial building encompassing 113,700 and 335,800 aggregate rentable square
feet, respectively for an aggregate sales price of $22.6 million. Operating
results for acquired properties are included in the consolidated financial
statements of the Company subsequent to their respective acquisition dates.

As a result of the properties developed by the Company subsequent to
December 31, 1999, net of the effect of properties disposed of during 2000,
rentable square footage in the Company's portfolio of stabilized operating
properties decreased approximately 0.2 million rentable square feet, or 1.6%,
to 12.4 million rentable square feet at December 31, 2000 compared to 12.6
million rentable square feet at December 31, 1999. As of December 31, 2000, the
Company's portfolio of stabilized operating properties was comprised of 83
Office Properties encompassing 6.6 million rentable square feet and 78
Industrial Properties encompassing 5.8 million rentable square feet. The
stabilized portfolio occupancy rate at December 31, 2000 was 97.0%, with the
Office and Industrial Properties 96.2% and 97.8% occupied, respectively, as of
such date.

Total revenues from Office Properties increased $22.9 million, or 21.0% to
$132.2 million for the year ended December 31, 2000 compared to $109.3 million
for the year ended December 31, 1999. Rental income from Office Properties
increased $20.8 million, or 21.5% to $117.3 million for the year ended
December 31, 2000 compared to $96.5 million for the year ended December 31,
1999. Of this increase, $19.1 million was generated by the office buildings
developed by the Company in 1999 and 2000 (the "Office Development
Properties") which was offset by a decrease of $1.5 million generated by
office buildings acquired during 1999, net of the effect of office properties
disposed of during 1999 and 2000 (the "Net Office Dispositions"). The
remaining $3.2 million increase was generated by the Core Office Portfolio and
represented a 3.7% increase in rental income for the Core Office Properties.
This increase was attributable to both an increase in rental rates and an
increase in average occupancy. Average occupancy for the Core Office
Properties increased 1.6%, to 95.4% at December 31, 2000 from 93.8% at
December 31, 1999.

Tenant reimbursements from Office Properties increased $3.1 million, or
28.4% to $14.1 million for the year ended December 31, 2000 compared to $11.0
million for the year ended December 31, 1999. An increase of $1.3 million in
tenant reimbursements was generated by the Office Development Properties net
of Net Office Dispositions. The remaining increase of $1.8 million in tenant
reimbursements was generated by the Core Office Properties which was primarily
due to the collection of amounts identified in common area maintenance
reconciliations. In addition, $0.8 million relates to an amount recorded for
estimated tenant reimbursement of supplemental real estate taxes accrued in
2000. Other income from Office Properties decreased $1.0 million, or 55.8% to
$0.8 million for the year ended December 31, 2000 compared to $1.8 million for
the same period in 1999. For the year ended December 31, 1999, other income
from Office Properties included $0.5 million in gains from the sale of 13
acres of undeveloped land in Calabasas and San Diego, California. In addition,
in 1999 the Company earned a $0.5 million consulting fee for assisting an
existing tenant with potential expansion plans. The remaining amounts in other
income from Office Properties for both periods consisted primarily of lease
termination fees, management fees and tenant late charges.

Total expenses from Office Properties increased $5.2 million, or 19.7% to
$31.8 million for the year ended December 31, 2000 compared to $26.6 million
for the year ended December 31, 1999. Property expenses increased $2.0
million, or 11.6% to $19.6 million for the year ended December 31, 2000
compared to $17.6 million for the year ended December 31, 1999. An increase of
$1.9 million in property expenses was attributable to the Office Development
Properties net of Net Office Dispositions. The remaining increase of
$0.1 million in property expenses was attributable to the Core Office
Properties and was due primarily to increased salaries and benefits for
property management personnel. Real estate taxes increased $2.9 million, or
38.7% to $10.5 million for the year ended December 31, 2000 compared to $7.6
million for the year ended December 31, 1999. An increase of $1.6 million was
attributable to the Office Development Properties net of Net Office
Dispositions. The remaining increase of $1.3 million was attributable to the
Core Office Properties. This increase at the Core Office Properties was due
primarily to a one-time $1.1 million adjustment for potential supplemental
real estate taxes. As noted above, the Company recorded $0.8 million in
estimated tenant reimbursements related to this one-time adjustment. Ground
lease expense increased $0.2 million for the year ended December 31, 2000
compared to the same period in 1999 primarily due to ground lease expense at
two of the Office Development Properties.

Net operating income, as defined, from Office Properties increased $17.7
million, or 21.4% to $100.4 million for the year ended December 31, 2000
compared to $82.7 million for the year ended December 31, 1999. Of this
increase, $14.9 million was generated by the Office Development Properties net
of Net Office Dispositions. The remaining increase of $2.8 million was
generated by the Core Office Properties and represented a 3.8% increase in net
operating income for the Core Office Properties.

million for the year ended December 31, 1999. Rental income from Industrial
Properties increased $0.3 million, or 0.6% to $43.9 million for the year ended
December 31, 2000 compared to $43.6 million for the year ended December 31,
1999. Of this increase, $1.7 million was generated by the industrial buildings
developed by the Company in 1999 and 2000 (the "Industrial Development
Properties") offset by a decrease of $4.9 million generated by the industrial
buildings disposed of during 1999 and 2000 (the "Industrial Dispositions").
The remaining $3.5 million increase was generated by the Core Industrial
Portfolio which represented a 9.9% increase in rental income for the Core
Industrial Properties. This increase was attributable to both an increase in
average occupancy of 0.7% and an increase in rental rates for the Core
Industrial Properties.

Tenant reimbursements from Industrial Properties remained consistent for
the years ended December 31, 2000 and 1999. A decrease of $0.3 million was
attributable to the Industrial Dispositions and the Industrial Development
Properties, which was offset by an increase of $0.3 million attributable to
the Core Industrial Portfolio. Other income from Industrial Properties
increased $0.8 million, or 322.6% to $1.1 million for the year ended December
31, 2000 compared to $0.3 million for the comparable period in 1999. Other
income for the years ended December 31, 2000 and 1999 consisted primarily of
lease termination fees.

Total expenses from Industrial Properties decreased $0.1 million, or 1.0%
to $7.8 million for the year ended December 31, 2000 compared to $7.9 million
for the year ended December 31, 1999. Property expenses increased $0.6
million, or 20.4% to $3.7 million for the year ended December 31, 2000
compared to $3.1 million for the year ended December 31, 1999. An increase of
$0.2 million in property expenses was attributable to the Industrial
Dispositions and the Industrial Development Properties. The remaining increase
of $0.4 million in property expenses was attributable to the Core Industrial
Portfolio. This increase was due to increased salaries and benefits for
property management personnel, and increases in variable costs due to higher
occupancy. Real estate taxes decreased $0.7 million, or 15.0% to $4.1 million
for the year ended December 31, 2000 compared to $4.8 million for the year
ended December 31, 1999. Of this decrease, $0.3 million was attributable to
the Net Industrial Dispositions and Industrial Development Properties. The
remaining $0.4 million decrease was attributable to the Core Industrial
Portfolio and was primarily due to the effect of prior year real estate taxes
which were successfully appealed and refunded to the Company in 2000.

Net operating income, as defined, from Industrial Properties increased $1.2
million, or 2.8% to $42.5 million for the year ended December 31, 2000
compared to $41.3 million for the year ended December 31, 1999. An increase of
$4.8 million generated by the Core Industrial Portfolio, which represented a
14.5% increase in net operating income for the Core Industrial Portfolio, was
offset by a $3.6 million decrease generated by the Industrial Dispositions and
the Industrial Development Properties.

Non-Property Related Income and Expenses

Interest income increased $3.4 million, or 291.7% to $4.6 million for the
year ended December 31, 2000 compared to $1.2 million for the year ended
December 31, 1999. This increase was due primarily to the receipt of interest
income on a note receivable acquired in May 2000.

General and administrative expenses increased $2.0 million, or 22.3% to
$11.1 million for the year ended December 31, 2000 compared to $9.1 million
for the year ended December 31, 1999. This increase was due primarily to
annual increases for salaries and benefits and a $0.8 million increase in non-
cash amortization of restricted stock grants.

Interest expense increased $12.8 million, or 48.7% to $39.1 million for the
year ended December 31, 2000 compared to $26.3 million for the same period in
1999, primarily due to a net increase in the Company's aggregate indebtedness
during 2000 and a general increase in market LIBOR rates during 2000. The
Company's weighted average interest rate increased approximately 0.5% to 8.2%
at December 31, 2000 compared to 7.7% at December 31, 1999.

Depreciation and amortization expense increased $7.3 million, or 21.7% to
$41.1 million for the year ended December 31, 2000 compared to $33.8 million
for the same period in 1999. The increase was primarily due to depreciation on
the Office and Industrial Development Properties developed by the Company in
1999 and 2000.

Income

Net income before net gains on dispositions of operating properties, equity
in income of unconsolidated subsidiary, and minority interests increased $0.1
million or 0.2% to $56.2 million for the year ended December 31, 2000 from
$56.1 million for the year ended December 31, 1999. The increase was due to
the increase in net operating income from the Office and Industrial Properties
of $17.7 million and $1.2 million, respectively, offset primarily by an
increase in interest expense of $12.8 million and an increase in depreciation
and amortization of $7.3 million.

Total revenues from Office Properties increased $13.2 million, or 13.7% to
$109.3 million for the year ended December 31, 1999 compared to $96.1 million
for the year ended December 31, 1998. Rental income from Office Properties
increased $14.4 million, or 17.5% to $96.5 million for the year ended December
31, 1999 compared to $82.1 million for the year ended December 31, 1998. Of
this increase, $7.2 million was generated by office buildings acquired during
1998 and 1999, net of the effect of office properties disposed of during 1999,
(the "Net Office Acquisitions") and $5.5 million was generated by the office
buildings developed by the Company in 1998 and 1999 (the "Office Development
Properties"). The remaining $1.7 million of the increase was generated by the
stabilized office properties owned at January 1, 1998 and still owned at
December 31, 1999 (the "Core Office Properties"), and represented a 2.6%
increase in rental income for the Core Office Properties. This increase was
primarily attributable to increases in rental rates. Average occupancy for the
Core Office Properties decreased 0.8%, to 93.4% at December 31, 1999 from
94.2% at December 31, 1998.

Tenant reimbursements from Office Properties remained consistent for the
years ended December 31, 1999 and 1998. An increase of $0.7 million in tenant
reimbursements generated by the Net Office Acquisitions and Office Development
Properties was offset by a decrease of $0.7 million in tenant reimbursements
generated by the Core Office Properties. This decrease in tenant
reimbursements for the Core Office Properties is due in part to the decrease
in average occupancy in this portfolio, and also to the decrease in property
expenses for this portfolio of properties as discussed below. Other income
from Office Properties decreased $1.2 million, or 39.8% to $1.8 million for
the year ended December 31, 1999 compared to $3.0 million for the same period
in 1998. For the year ended December 31, 1999, other income from Office
Properties included $0.5 million in gains from the sale of 13 acres of
undeveloped land in Calabasas and San Diego, California and $0.8 million in
lease termination fees from Core Office Portfolio properties. Other income
from Office Properties for the year ended December 31, 1998 included a $1.9
million net lease termination fee from an office property in San Diego,
California and $0.5 million in lease termination fees at various properties.
In addition, in 1998 the Company earned a $0.5 million consulting fee for
assisting an existing tenant with potential expansion plans. The remaining
amounts in other income from Office Properties for both periods consisted
primarily of management fees and tenant late charges.

Total expenses from Office Properties increased $2.4 million, or 9.8% to
$26.5 million for the year ended December 31, 1999 compared to $24.1 million
for the year ended December 31, 1998. Property expenses increased $1.2
million, or 7.2% to $17.6 million for the year ended December 31, 1999
compared to $16.4 million for the year ended December 31, 1998. An increase of
$1.6 million in property expenses attributable to the Net Office Acquisitions
and the Office Development Properties was offset by a $0.4 million decrease in
property expenses at the Core Office Properties. This decrease was primarily
attributable to renegotiated property insurance premiums and a decrease in
electricity expense resulting from the implementation of energy management
systems in several of the buildings. Real estate taxes increased $1.0 million,
or 15.6% to $7.6 million for the year ended December 31, 1999 compared to $6.6
million for the year ended December 31, 1998. An increase of $1.1 million
attributable to the Net Office Acquisitions and the Office Development
Properties was offset by a decrease of $0.1 million for the Core Office
Properties. This decrease at the Core Office Properties was due primarily to
the effects of prior year property taxes which were successfully appealed and
refunded to the Company in 1999. Ground lease expense increased $0.2 million
for the year ended December 31, 1999 compared to the same period in 1998
primarily due to a full year of ground lease expense at one of the 1998 office
acquisition properties.

Net operating income, as defined, from Office Properties increased $10.8
million, or 15.0% to $82.7 million for the year ended December 31, 1999
compared to $71.9 million for the year ended December 31, 1998. Of this
increase, $8.8 million was generated by the Net Office Acquisitions and the
Office Development Properties. The remaining increase of $2.0 million was
generated by the Core Office Properties and represented a 3.8% increase in net
operating income for the Core Office Properties.

Total revenues from Industrial Properties increased $9.9 million, or 25.3%
to $49.2 million for the year ended December 31, 1999 compared to $39.3
million for the year ended December 31, 1998. Rental income from Industrial
Properties increased $8.5 million, or 24.1% to $43.7 million for the year
ended December 31, 1999 compared to $35.2 million for the year ended December
31, 1998. Of this increase, $3.3 million was generated by the industrial
buildings acquired during 1998 and 1999, net of the effect of the industrial
buildings disposed of during 1999 (the "Net Industrial Acquisitions") and $4.6
million was generated by the industrial buildings developed by the Company in
1998 and 1999 (the "Industrial Development Properties"). The remaining $0.6
million of the increase was generated by the stabilized industrial buildings
owned at January 1, 1998 and still owned at December 31, 1999 (the "Core
Industrial Properties"), and represented a 2.0% increase in rental income for
the Core Industrial Properties. This increase was attributable to both an
increase in average occupancy of 0.6% and an increase in rental rates for this
portfolio.

Tenant reimbursements from Industrial Properties increased $1.4 million, or
33.8% to $5.4 million for the year ended December 31, 1999 compared to $4.0
million for year ended December 31, 1998. Of this increase, $1.2 million was
attributable to the Net Industrial Acquisitions and the Industrial Development
Properties. The remaining $0.2 million was attributable to the Core Industrial
Properties and was primarily due to an increase in real estate taxes
reimbursable by tenants. Other income from Industrial Properties increased
$0.1 million, or 77.1% to $0.2 million for the year ended December 31, 1999
compared to $0.1 million for the comparable period in 1998. Other income for
the years ended December 31, 1999 and 1998 consisted primarily of lease
termination fees.

Total expenses from Industrial Properties increased $1.2 million, or 17.4%
to $7.9 million for the year ended December 31, 1999 compared to $6.7 million
for the year ended December 31, 1998. Property expenses increased $0.2
million, or 7.2% to $3.1 million for the year ended December 31, 1999 compared
to $2.9 million for the year ended December 31, 1998. An increase of $0.6
million in property expenses attributable to the Net Industrial Acquisitions
and the Industrial Development Properties was offset by a decrease of $0.4
million in property expenses at the Core Industrial Properties. This decrease
was primarily due to renegotiated property insurance premiums and a decrease
in electricity expense resulting from the implementation of energy management
systems at several of the buildings. Real estate taxes increased $1.0 million,
or 25.3% to $4.8 million for the year ended December 31, 1999 compared to $3.8
million for the year ended December 31, 1998. Of this increase, $0.8 million
was attributable to the Net Industrial Acquisitions and Industrial

36


Development Properties. The remaining $0.2 million increase was generated by
the Core Industrial Properties and was primarily due to acquisition related
assessments on industrial buildings acquired by the Company in 1997.

Net operating income, as defined, from Industrial Properties increased $8.8
million, or 26.9% to $41.4 million for the year ended December 31, 1999
compared to $32.6 million for the year ended December 31, 1998. Of this
increase, $7.8 million was generated by the Net Industrial Acquisitions and
the Industrial Development Properties. The remaining increase of $1.0 million
was generated by the Core Industrial Properties and represented a 3.7%
increase in net operating income for the Core Industrial Properties.

Non-Property Related Income and Expenses

Interest income decreased $0.5 million, or 30.8% to $1.2 million for the
year ended December 31, 1999 compared to $1.7 million for the year ended
December 31, 1998. This decrease was due primarily to the receipt of interest
income on notes receivable from related parties for three months during the
year ended December 31, 1999 versus seven months for the year ended December
31, 1998.

General and administrative expenses increased $1.4 million, or 17.5% to
$9.1 million for the year ended December 31, 1999 compared to $7.7 million for
the year ended December 31, 1998. This increase was due primarily to annual
increases for salaries and benefits and increased depreciation related to the
Company's increased investment in its information systems.

Interest expense increased $5.7 million, or 27.9% to $26.3 million for the
year ended December 31, 1999 compared to $20.6 million for the same period in
1998, primarily due to a net increase in the Company's aggregate indebtedness
during 1999 and a general increase in market LIBOR rates during 1999. The
Company's weighted average interest rate increased 0.4% to 7.7% at December
31, 1999 compared to 7.3% at December 31, 1998.

Depreciation and amortization expense increased $7.6 million, or 29.0% to
$33.8 million for the year ended December 31, 1999 compared to $26.2 million
for the same period in 1998. The increase was primarily due to depreciation on
the Net Office and Industrial Acquisitions and the Office and Industrial
Development Properties.

Income

Net income before gains on dispositions of operating properties, equity in
income of unconsolidated subsidiary, and minority interests increased $6.1
million, or 12.2% to $56.1 million for the year ended December 31, 1999 from
$50.0 million for the year ended December 31, 1998. The increase was primarily
due to the increase in net operating income from the Office and Industrial
Properties of $10.8 million and $8.8 million, respectively, offset primarily
by an increase in interest expense of $5.7 million and an increase in
depreciation and amortization of $7.6 million.

Liquidity and Capital Resources

The Company has a $400 million unsecured revolving credit facility (the
"Credit Facility") which bears interest at an annual rate between LIBOR plus
1.13% and LIBOR plus 1.75% (8.26% at December 31, 2000), depending upon the
Company's leverage ratio at the time of borrowing, and matures in November
2002. As of December 31, 2000, the Company had borrowings of $191 million
outstanding under the Credit Facility and availability of approximately
$75.0 million. The Company uses the Credit Facility to finance development
expenditures, to fund potential undeveloped land acquisitions and for general
corporate purposes.

In September 2000, the Company borrowed $100.0 million under an unsecured
debt facility from a bank group led by The Chase Manhattan Bank and Morgan
Guaranty Trust Company of New York. The $100.0 million facility, which matures
in September 2002 with two one-year extension options, requires monthly
interest-only

37


payments based upon an annual interest rate which ranges between LIBOR plus
1.13% and LIBOR plus 1.75% (8.19% at December 31, 2000), depending upon the
Company's leverage ratio at the time of borrowing.

In April 2000, one of the Development LLCs obtained a non-recourse
construction loan with a total commitment of $57.0 million. The construction
loan, which had an outstanding balance of approximately $50.1 million and an
annual interest rate between LIBOR plus 2.00% and LIBOR plus 2.70% at
December 31, 2000, matures in April 2002, with the option to extend for up to
two six-month periods. The proceeds from the construction loan are being used
to finance the development of part of a multi-phased office project that the
Company is developing in San Diego, California, with The Allen Group, a group
of affiliated real estate development and investment companies based in San
Diego, California. In October 2000, the construction loan agreement was
modified to increase the total commitment to $61.0 million, and to decrease
the interest rate on $37.2 million of the loan from LIBOR plus 2.70% to LIBOR
plus 2.00%. The project is expected to encompass approximately 550,000
rentable square feet of office space upon completion of all phases. The
construction loan is secured by the land for the entire project, the three
phases of the project that the Company had completed as of December 31, 2000,
and all improvements on one of the two remaining buildings to be constructed.

In June 2000, one of the Development LLCs borrowed $22.0 million under a
mortgage loan that requires monthly principal and interest payments based on a
floating annual interest rate of LIBOR plus 1.75%, amortizes over 25 years,
and matures in June 2004. The mortgage loan is secured by two buildings that
the Company developed with The Allen Group and completed in the fourth quarter
of 1999. The Development LLC used the proceeds from the mortgage loan to repay
cash received from the Operating Partnership. The Operating Partnership used
the proceeds to repay borrowings under the Company's Credit Facility.

In October 2000, the Company obtained a construction loan with a total
commitment of $18.5 million. The construction loan, which had an outstanding
balance at December 31, 2000 of approximately $9.4 million, bears interest at
an annual rate of LIBOR plus 1.75% and matures in October 2002, with the
option to extend for twelve months. The proceeds from the construction loan
are being used to finance the development of an office project in San Diego,
California that is expected to encompass an aggregate of approximately 102,900
rentable square feet upon completion. The construction loan is secured by the
improvements to be constructed.

In October 2000, the Company obtained a construction loan with a total
commitment of $13.3 million. The construction loan, which had an outstanding
balance at December 31, 2000 of approximately $4.7 million, bears interest at
an annual rate of LIBOR plus 1.75% and matures in April 2002, with the option
to extend for up to two six-month periods. The proceeds from the construction
loan are being used to finance the development of two office buildings in San
Diego, California that are expected to encompass an aggregate of approximately
119,000 rentable square feet upon completion. The construction loan is secured
by a first deed of trust on the project.

In November 2000, one of the Development LLCs obtained a construction loan
with a total commitment of $11.8 million. The construction loan, which had an
outstanding balance at December 31, 2000 of approximately $11.4 million, bears
interest at an annual rate of LIBOR plus 3.00% and matures in November 2002,
with the option to extend for up to two six-month periods. The proceeds from
the construction loan are being used to finance the development costs of an
office building in San Diego, California that encompasses an aggregate of
approximately 76,200 rentable square feet. The construction loan is secured by
a first deed of trust on the project.

In December 2000, the Company borrowed $12.8 million under a mortgage loan
that is secured by one Office Property requires monthly principal and interest
payments based on an annual interest rate of 8.13% and matures in November
2014. The property securing this loan also secures the Company's $10.6 million
mortgage loan. The Company used the proceeds from the mortgage loan to repay
borrowings under the Credit Facility and to finance development expenditures.

construction debt at 8.50% that expires in April 2002. The notional
amount of the cap increases over the life of the agreement as the balance

notional amount of the interest rate cap was approximately $42.0 million.

(5) The percentage of fixed rate debt to total debt at December 31, 2000 does
not take into consideration the portion of floating rate debt capped by
the Company's interest-rate cap agreements. Including the effects of the

In December 1999, the Company announced the approval of its share
repurchase program, pursuant to which the Company is authorized to repurchase
up to an aggregate of 3.0 million shares of its outstanding common stock,

remainder of 2000. Repurchases to date total 2,264,300 shares for an aggregate
repurchase price of $46.5 million or $20.54 per share. Repurchases were funded
primarily through working capital, borrowings on the Company's unsecured
revolving credit facility, and proceeds received from the Company's
disposition program. Depending on market conditions, the Company will evaluate
the opportunity to repurchase additional shares in the future.

40


In February 1998, the SEC declared effective the Company's "shelf"
registration statement on Form S-3 with respect to $400 million of the
Company's equity securities. As of March 22, 2001, an aggregate of
$313 million of equity securities were available for issuance under the
registration statement.

Capital Expenditures

As of December 31, 2000, the Company had an aggregate of approximately
964,400 rentable square feet of office space that was either under
construction or committed for construction at a total budgeted cost of
approximately $232 million. The Company has spent an aggregate of
approximately $111 million on these projects as of December 31, 2000. The
Company intends to finance $18 million of the remaining $121 million of
presently budgeted development costs with proceeds from construction loans
obtained in 2000. The Company intends to finance the remaining $103 million of
budgeted development costs with additional construction loan financing,
proceeds from the Company's dispositions program of non-strategic assets,
borrowings under the Credit Facility and from working capital.

In connection with an agreement signed with The Allen Group in October
1997, the Company agreed to purchase one office property encompassing
approximately 128,000 rentable square feet, subject to the property meeting
certain occupancy thresholds and other tenancy requirements. The purchase
price for this property will be determined at the time of acquisition based on
the net operating income at the time of acquisition. The Company expects that
in the event that this acquisition does occur, it would be financed with
borrowings under the Credit Facility and the issuance of common limited
partnership units of the Operating Partnership.

The Company believes that it will have sufficient capital resources to
satisfy its obligations and planned capital expenditures for the next twelve
months. The Company expects to meet its long-term liquidity requirements
including possible future development and undeveloped land acquisitions,
through retained cash flow, borrowings under the Credit Facility, proceeds
from the Company's dispositions program, long-term secured and unsecured
borrowings, or the issuance of common or preferred units of the Operating
Partnership.

(1) Includes only tenants with lease terms of 12 months or longer. Excludes
leases for amenity, parking, retail and month-to-month tenants.

Capital expenditures may fluctuate in any given period subject to the
nature, extent, and timing of improvements required to be made to the
properties. The Company believes that all of its Office and Industrial
Properties are well maintained and, based on engineering reports obtained
within the last five years, do not require significant capital improvements.
Tenant improvements and leasing costs may also fluctuate in any given year
depending upon factors such as the property, the term of the lease, the type
of lease, the involvement of external leasing agents and overall market
conditions.

Distribution Policy

The Company makes quarterly distributions to common stockholders from cash
available for distribution and, if necessary to meet REIT distribution
requirements and maintain its REIT status, may use borrowings under the Credit
Facility. All such distributions are at the discretion of the Board of
Directors. Amounts accumulated for distribution are invested primarily in
interest-bearing accounts and short-term interest-bearing securities, which
are consistent with the Company's intention to maintain its qualification as a
REIT. Such investments may include, for example, obligations of the Government
National Mortgage Association, other governmental agency securities,
certificates of deposit and interest-bearing bank deposits.

43


Historical Cash Flows

The principal sources of funding for development, acquisitions, and capital
expenditures are the Credit Facility, cash flow from operating activities,
secured and unsecured debt financing and proceeds from the Company's
dispositions program. The Company's net cash provided by operating activities
decreased $10.6 million, or 12.5% to $74.0 million for the year ended December
31, 2000 compared to $84.6 million for the year ended December 31, 1999. This
decrease was primarily attributable to timing differences in payments of
accounts payable and other receivable balances at the end of each comparable
period.

Net cash used in investing activities decreased $75.1 million, or 39.0% to
$117.7 million for the year ended December 31, 2000 compared to $192.8 million
for the year ended December 31, 1999. Cash used in investing activities for
the year ended December 31, 2000 consisted primarily of the purchase of 20
acres of undeveloped land for $15.5 million less $8.5 million for a mortgage
note payable issued in connection with the acquisition, expenditures for
construction in progress of $159.4 million, $15.9 million in additional tenant
improvements and capital expenditures, and $45.3 million paid to acquire a
note receivable, net of the effect of net proceeds received from the sale of
nine office and nine industrial buildings of approximately $110.6 million.
Cash used in investing activities for the year ended December 31, 1999
consisted primarily of the purchase of three office properties for $30.6
million less $3.6 million of contributed value in exchange for which the
Company issued common limited partnership units of the Operating Partnership
and the repayment of an existing $2.3 million note receivable, the purchase of
the minority interest in one office complex for $1.2 million, the purchase of
86 acres of undeveloped land for $38.7 million less $6.3 million of
contributed value in exchange for which the Company issued common limited
partnership units of the Operating Partnership, expenditures for construction
in progress of $144.0 million, and $17.0 million in additional tenant
improvements and capital expenditures, net of the effect of net proceeds
received from the sale of five office and five industrial properties of
approximately $22.6 million and the sale of 13 acres of undeveloped land of
approximately $5.1 million.

Net cash provided by financing activities decreased $92.6 million, or 72.5%
to $35.2 million for the year ended December 31, 2000 as compared to $127.8
million for the year ended December 31, 1999. Cash provided by financing
activities for the year ended December 31, 2000 consisted primarily of $194.6
million in net proceeds from the issuance of secured and unsecured debt
partially offset by $37.0 million in repayments to the Credit Facility, $54.2
million in distributions paid to common stockholders and common unitholders,
$41.3 million paid for securities purchased in the Company's stock repurchase
program and a $28.4 million increase in restricted cash representing cash
received from property dispositions that are held at Qualified Intermediaries
for future use in tax deferred exchanges. Cash provided by financing
activities for the year ended December 31, 1999 consisted primarily of the
issuance of $45.0 million of 9.250% Series D Preferred units (net of $1.2
million aggregate transaction costs) and $186.7 million in net proceeds from
the issuance of secured debt partially offset by $54.0 million in
distributions paid to common stockholders and common unitholders,
$44.0 million in repayments to the Credit Facility and $5.4 million paid for
securities purchased in the Company's stock repurchase program.

Funds From Operations

Industry analysts generally consider Funds From Operations, as defined by
NAREIT, an alternative measure of performance for an equity REIT. Funds From
Operations is defined by NAREIT to mean net income (loss) before minority
interests of common unitholders (computed in accordance with GAAP), excluding
gains (or losses) from debt restructuring and sales of property, plus real
estate related depreciation and amortization (excluding amortization of
deferred financing costs and depreciation of non-real estate assets), and
after adjustment for unconsolidated partnerships and joint ventures. The
Company considers Funds From Operations an appropriate measure of performance
of an equity REIT because it is predicated on cash flow analyses. The Company
believes that in order to facilitate a clear understanding of the historical
operating results of the Company, Funds From Operations should be examined in
conjunction with net income as presented in the financial statements included
elsewhere in this report. The Company computes Funds From Operations in
accordance with standards established by the Board of Governors of NAREIT in
its March 1995 White Paper as

44


clarified by the November 1999 NAREIT National Policy Bulletin which became
effective on January 1, 2000, which may differ from the methodologies used by
other equity REITs and, accordingly, may not be comparable to Funds From
Operations published by such other REITs. Funds From Operations should not be
considered as an alternative to net income (loss) (computed in accordance with
GAAP) as an indicator of the properties' financial performance or to cash flow
from operating activities (computed in accordance with GAAP) as an indicator
of the properties' liquidity, nor is it indicative of funds available to fund
the properties' cash needs, including the Company's ability to pay dividends
or make distributions.

The following table presents the Company's Funds from Operations, by
quarter, for the years ended December 31, 2000, 1999 and 1998:

Inflation

The majority of the Company's leases require tenants to pay most operating
expenses, including real estate taxes and insurance, and increases in common
area maintenance expenses. The effect of such provisions is to reduce the
Company's exposure to increases in costs and operating expenses resulting from
inflation.

New Accounting Pronouncements

The Financial Accounting Standards Board issued Statement of Financial
Accounting Standards No. 133 "Accounting for Derivative Instruments and
Hedging Activities" ("SFAS 133") and Statement of Financial Accounting
Standards No. 138 "Accounting for Certain Derivative Instruments and Certain
Hedging Activities, an Amendment of FASB Statement No. 133" ("SFAS 138") in
June 1998 and June 2000, respectively. SFAS 133 and SFAS 138 are effective for
fiscal years beginning after June 15, 2000 and require all derivatives to be
recorded on the balance sheet at fair value. If the derivative instrument
qualifies as a hedge, depending on the nature of the hedge, changes in fair
value of the derivative will either be offset against the change in fair value
of the hedged assets, liabilities, or firm commitments through earnings or
recognized in other comprehensive income until the hedged item is recognized
in earnings. The ineffective portion of a derivative's change in fair value
will be immediately recognized in earnings. The Company adopted SFAS 133 and
138 on January 1, 2001 and recorded a $2.0 million non-cash charge to other
comprehensive income and a $1.4 million non-cash charge to the income
statement as the cumulative effect of a change in accounting principle.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Information about the Company's changes in primary risk exposures from
December 31, 1999 to December 31, 2000 and changes subsequent to December 31,
2000, is incorporated herein by reference from "Item 2: Management Discussion
and Analysis of Financial Condition and Results of Operations--Liquidity and
Capital Resources."

Tabular Presentation of Market Risk

The tabular presentations below provide information about the Company's
interest rate sensitive financial and derivative instruments as of December
31, 2000 and 1999. All of the Company's interest rate sensitive financial and
derivative instruments are designated as held for purposes other than trading.

Presentation at December 31, 2000

For the Credit Facility, the table presents the assumption that the
outstanding principal balance at December 31, 2000 will be paid upon the
Credit Facility's maturity in November 2002. The table also presents the
expected maximum contractual weighted average interest rate index for
outstanding Credit Facility borrowings from 2001 through 2002.

For variable rate secured debt and unsecured term debt, the table presents
the assumption that all available debt extension options will either be
exercised or extended and that the outstanding principal balance at December
31, 2000 will be paid upon the extended debt maturities. The table also
presents the contractual weighted average interest rate index for outstanding
variable rate mortgage debt borrowings from 2001 through 2004.

For fixed rate secured debt, the table presents the assumption that the
outstanding principal balance at December 31, 2000 will be paid according to
scheduled principal payments and that the Company will not prepay any of the
outstanding principal balance. The table also presents the related contractual
weighted-average interest rate at December 31, 2000 for outstanding fixed rate
secured debt borrowings from 2001 through 2005 and thereafter.

For the Series A and Series C Cumulative Redeemable Preferred units
(collectively, the "Series A and Series C Preferred units") the table reflects
the assumption that the Company is not contractually obligated to repay the
outstanding balance of the Series A and Series C Preferred units since the
Series A and Series C Preferred units will either remain outstanding or be
converted into shares of the Company's 8.075% Series A and 9.375% Series C
Cumulative Redeemable Preferred stock, respectively, in 2008 when the Series A
and Series C Preferred units become exchangeable at the option of the majority
of the holders. For the Series D Cumulative Redeemable Preferred units (the
"Series D Preferred units"), the table reflects the assumption that the
Company is not contractually obligated to repay the outstanding balance of the
Series D Preferred units since the Series D Preferred units will either remain
outstanding or be converted into shares of the 9.250% Series D Cumulative
Redeemable Preferred stock in 2009 when the Series D Preferred units become
exchangeable at the option of the majority of the holders. The table also
presents the related weighted-average interest rate at December 31, 2000 for
outstanding collectively, Series A, C and D Preferred units from 2001 through
the exchange date. The same interest rates will apply when the collectively,
Series A, C or D Preferred units are exchanged into the respective Series A, C
or D Cumulative Redeemable Preferred stock.

47


For the interest rate cap agreement, the table presents the notional
amount, cap rate and the related interest rate index upon which the cap rate
is based, by contractual maturity date. For the interest rate swap agreement,
the table presents the notional amount, maximum contractual fixed pay rate,
and related interest rate index upon which the floating receive rate is based,
by contractual maturity date. Notional amounts are used solely to calculate
the contractual cash flow to be received under the contract and do not reflect
outstanding principal balances at December 31, 2000.

outstanding principal balance. The table also presents the related weighted-
average interest rate at December 31, 1999 for outstanding fixed rate mortgage
debt borrowings from 2000 through 2004 and thereafter.

For the Series A, C and D Preferred units the table presents the same
assumptions as discussed for the presentation at December 31, 2000.

INDEPENDENT AUDITORS' REPORT

To the Board of Directors and Stockholders of Kilroy Realty Corporation:

We have audited the accompanying consolidated balance sheets of Kilroy
Realty Corporation (the "Company") as of December 31, 2000 and 1999 and the
related consolidated statements of operations, shareholders' equity, and cash
flows for each of the three years in the period ended December 31, 2000. Our
audits also included the financial statement schedule listed in the index at
Item 8. These financial statements and the financial statement schedule are
the responsibility of the management of the Company. Our responsibility is to
express an opinion on these financial statements and the financial statement
schedule based on our audits.

We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. Those standards require that we plan
and perform the audits 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, such consolidated financial statements present fairly, in
all material respects, the financial position of the Company as of December
31, 2000 and 1999, and the results of their operations and their 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
of America. Also in our opinion, such financial statement schedule, when
considered in relation to the basic consolidated financial statements taken as
a whole, presents fairly in all material respects, the information set forth
therein.

KILROY REALTY CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Three Years Ended December 31, 2000

1. Organization and Ownership

Kilroy Realty Corporation (the "Company") develops, owns, and operates
office and industrial real estate located in California, Washington, Nevada
and Arizona. The Company, which qualifies and operates as a self-administered
real estate investment trust ("REIT") under the Internal Revenue Code of 1986,
as amended, commenced operations upon the completion of its initial public
offering in January 1997. The Company is the successor to the real estate
business of the Kilroy Group, which consisted of the combination of Kilroy
Industries ("KI") and various entities, the properties of which were under the
common control of KI and/or its stockholders, including the Company's Chairman
of the Board of Directors, John B. Kilroy, Sr., and the Company's President
and Chief Executive Officer, John B. Kilroy, Jr.

As of December 31, 2000, the Company's portfolio of stabilized operating
properties was comprised of 83 office buildings (the "Office Properties") and
78 industrial buildings (the "Industrial Properties," and together with the
Office Properties, the "Properties") which encompassed approximately 6.6
million and 5.8 million rentable square feet, respectively, and was 97.0%
occupied. The Properties include 21 properties developed by the Company and
stabilized during 2000 and 1999 which encompass an aggregate of approximately
809,000 and 1.2 million rentable square feet, respectively. All but ten of the
Properties are included in Southern California.

The Company's stabilized portfolio excludes projects currently under
construction or in pre-development and "lease-up" properties. The Company
defines "lease-up" properties as properties recently developed by the Company
that have not yet reached 95% occupancy. The Company had one lease-up property
at December 31, 2000, encompassing an aggregate of 197,300 rentable square
feet, which stabilized on January 15, 2001. As of December 31, 2000, the
Company had eleven office properties under construction or committed for
construction which when completed are expected to encompass an aggregate of
approximately 964,400 rentable square feet. All of the Company's development
projects are located in Southern California.

The Company owns its interests in all of the Properties through Kilroy
Realty, L.P. (the "Operating Partnership") and Kilroy Realty Finance
Partnership, L.P. (the "Finance Partnership"). The Company conducts
substantially all of its activities through the Operating Partnership in
which, as of December 31, 2000 and 1999, it owned an 87.6% and 86.8% general
partnership interest, respectively. The remaining 12.4% and 13.2% limited
partnership interest in the Operating Partnership as of December 31, 2000 and
1999, respectively, was owned by certain of the Company's executive officers
and directors, certain of their affiliates, and other outside investors (see
Note 8). Kilroy Realty Finance, Inc, ("Finance Inc."), a wholly-owned
subsidiary of the Company, is the sole general partner of the Finance
Partnership and owns a 1% general partnership interest. The Operating
Partnership owns the remaining 99% limited partnership interest.

During the first of quarter 1999, the Company, through the Operating
Partnership, became a 50% managing partner in two limited liability companies,
Kilroy Gateway Partners, L.L.C. and Kilroy Carmel Partners, L.L.C.
(collectively, the "Development LLCs") as a result of the acquisitions of
certain undeveloped land and the simultaneous contribution of such land to the
Development LLCs (see Notes 3 and 13). The Development LLCs were formed to
develop two multi-phased office projects in San Diego, California. The Allen
Group, a group of affiliated real estate development and investment companies
based in San Diego, California, is the other 50% joint venture partner. Unless
otherwise indicated, all references to the Company include the Operating
Partnership, the Finance Partnership, the Development LLCs, and all wholly-
owned subsidiaries and controlled entities.

F-7


KILROY REALTY CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


As of December 31, 2000, the Operating Partnership owned 100% of the non-
voting preferred stock and a 95% economic interest in Kilroy Services, Inc.
("KSI"). 100% of the voting interest was held by John B. Kilroy, Sr., the
Chairman of the Company's Board of Directors, and John B. Kilroy, Jr., the
Company's President and Chief Executive Officer. Prior to December 31, 2000,
the operating results of the development services business conducted by KSI
were accounted for under the equity method of accounting. On January 1, 2001,
KSI was merged into a newly formed entity, Kilroy Services, LLC ("KSLLC"). In
connection with the merger, the interests held by Messers Kilroy were
liquidated resulting in Messers Kilroy receiving $8,000 in cash and KSLLC
became a wholly-owned subsidiary of the Company. As a result, KSLLC will be
consolidated for financial reporting purposes beginning January 1, 2001.

2. Basis of Presentation and Significant Accounting Policies

Basis of Presentation:

The consolidated financial statements of the Company include the
consolidated financial position and results of operations of the Company, the
Operating Partnership, the Finance Partnership and all wholly-owned
subsidiaries and controlled entities. The consolidated financial statements as
of and for the years ended December 31, 2000 and 1999 also include the
consolidated financial position and results of operations of the Development
LLCs. The Development LLCs are consolidated for financial reporting purposes
since the Company holds significant control over the entities through a 50%
managing partner ownership interest, combined with the ability to control all
significant development and operating decisions. The operating results of the
development services business conducted by Kilroy Services, Inc. ("KSI") are
accounted for under the equity method of accounting. All significant
intercompany balances and transactions have been eliminated in the
consolidated financial statements.

Significant Accounting Policies:

Operating properties--Operating properties are carried at the lower of
historical cost less accumulated depreciation or estimated fair value. The
cost of operating properties includes the purchase price or development costs
of the properties. Costs incurred for the acquisition, renovation and
betterment of the operating properties are capitalized to the Company's
investment in that property. Maintenance and repairs are charged to expense as
incurred. The Company's stabilized portfolio of operating properties consists
of all of the Company's Office and Industrial Properties, excluding projects
currently under construction or in pre-development and lease-up properties.
Lease-up properties are included in land and improvements and building and
improvements on the consolidated balance sheets.

The Company evaluates fair value for financial reporting purposes on a
property by property basis using future undiscounted cash flows, excluding
interest charges. In the event that periodic assessments or other factors
reveal a potential impairment condition, the Company would recognize an
impairment loss to the extent the carrying amount exceeded the fair value of
the property. The Company had not recorded any such impairment losses at
December 31, 2000, 1999 and 1998.

Depreciation and amortization--The cost of buildings and improvements are
depreciated on the straight-line method over estimated useful lives of 25 to
40 years for buildings and the shorter of the lease term or useful life,
ranging from one to 20 years, for tenant improvements. Depreciation expense
for buildings and improvements for the three years ended December 31, 2000,
1999 and 1998, was $35.6 million, $29.0 million, and $23.7 million,
respectively.

Construction in progress--Project costs clearly associated with the
development and construction of a real estate project are capitalized as
construction in progress. In addition, interest, real estate taxes and other
costs are

F-8


KILROY REALTY CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

capitalized during the period in which activities necessary to get the
property ready for its intended use are in progress. Once the development and
construction of the building shell of a real estate project is completed, the
costs capitalized to construction in progress are transferred to land and
improvements and buildings and improvements on the consolidated balance sheets
as the historical cost of the property.

Cash and cash equivalents--The Company considers all money market funds
with an original maturity of three months or less at the date of purchase to
be cash equivalents.

Restricted cash--Restricted cash consists of cash held as collateral to
provide credit enhancement for the Company's mortgage debt, cash reserves for
property taxes, capital expenditures and tenant improvements, and at December
31, 2000, $28.4 million in proceeds received from property dispositions that
are held at Qualified Intermediaries for future use in tax-deferred exchanges.

Tenant receivables and related revenue recognition--Leases with tenants are
accounted for as operating leases. Minimum annual rentals are recognized on a
straight-line basis over the term of the related lease. Unbilled deferred rent
receivables represent the amount that straight-line rental income exceeds
rents currently due under the lease agreement. Included in tenant receivables
are tenant reimbursements which are comprised of additional amounts receivable
from tenants based on common area maintenance expenses and certain other
expenses that are accrued in the period in which the related expenses are
incurred.

Tenant receivables and unbilled deferred rent receivables are carried net
of an allowance for uncollectible tenant receivables and unbilled deferred
rent. Management's determination of the adequacy of the allowance is based
upon evaluations of individual receivables, past loss experience, current
economic conditions, and other relevant factors. The allowance is increased by
provisions charged against income.

Deferred financing and leasing costs--Costs incurred in connection with
debt financing and property leasing are capitalized as deferred financing and
leasing costs. Deferred financing costs include loan fees which are amortized
using the effective interest method over the terms of the respective loans.
Deferred leasing costs include leasing commissions which are amortized on the
straight-line method over the initial lives of the leases which range from one
to 15 years.

Minority interests--Minority interests represent the preferred and common
limited partnership interests in the Operating Partnership and interests held
by The Allen Group in the Development LLCs.

Other income--Other income includes revenue earned from lease termination
fees and management fees. For the year ended December 31, 2000, other income
also included the equity in earnings from unconsolidated real estate (see Note
13) and for the year ended December 31, 1999, other income includes gains on
dispositions of undeveloped land.

Income taxes--The Company believes it qualifies and intends to continue to
qualify as a REIT under Sections 856 through 860 of the Internal Revenue Code
of 1986, as amended (the "Code"), beginning with the

F-9


KILROY REALTY CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

taxable year ended December 31, 1997. As a REIT, the Company is generally not
subject to corporate Federal income taxes so long as it distributes at least
95% of its taxable income to its stockholders and satisfies certain quarterly
requirements of the Code relating to the composition of its income and assets.
Pursuant to recently enacted legislation the 95% distribution requirement will
be reduced to 90% effective for taxable years beginning after December 31,
2000. The Company had met all of its REIT distribution and technical
requirements at December 31, 2000, 1999 and 1998. State income tax
requirements are essentially the same as Federal tax requirements.

Fair value of financial instruments--The Company calculates the fair value
of financial instruments using available market information and appropriate
present value or other valuation techniques. Those techniques are
significantly affected by the assumptions used, including the discount rate
and estimates of future cash flows. In that regard, the derived fair value
estimates cannot be substantiated by comparison to independent markets and in
many cases, could not be realized in immediate settlement of the instrument.
Fair values for certain financial instruments and all non-financial
instruments are not required to be disclosed. Accordingly, the aggregate fair
value amounts presented do not represent the underlying value of the Company
at December 31, 2000 and 1999.

Derivative financial instruments--The Company periodically enters into
derivative financial instruments such as interest rate caps and interest rate
swaps to effectively limit interest expense on the Company's floating rate
debt during periods of rising interest rates. These derivative financial
instruments are designated as hedges and deferral accounting has been applied.
Net amounts paid or received under these agreements are recognized as
adjustments to interest expense The initial premiums on cap agreements are
amortized over the life of the agreement using the straight-line method.

Use of estimates--The preparation of financial statements in conformity
with accounting principles generally accepted in the United States of America
requires management 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 reported periods. Actual results could
differ from those estimates.

Reclassifications--Certain prior year amounts have been reclassified to
conform to the current year's presentation.

Concentration of credit risk--151 of the Company's total 161 properties are
located in Southern California. The ability of the tenants to honor the terms
of their respective leases is dependent upon the economic, regulatory and
social factors affecting the communities in which the tenants operate.

For the year ended December 31, 2000, the Company's largest tenant as
defined by the percentage of the Company's total base rental revenues, The
Boeing Company, accounted for approximately 9.2% of the Company's total base
revenues. During the years ended December 31, 1999 and 1998, Hughes Space and
Communications was the Company's largest tenant and accounted for 6.4% and
7.4% of the Company's base rental revenues. During the year ended December 31,
2000, The Boeing Company acquired Hughes Space & Communications' business and
related operations. Had this merger occurred prior to the year 2000, The
Boeing Company and Hughes Space and Communications together accounted for
approximately 10.2% and 11.6% of the Company's total base revenues, for the
years ended December 31, 1999 and 1998, respectively. At December 31, 2000,
the Company had no outstanding tenant receivables from this tenant.

The Company has cash in financial institutions which is insured by the
Federal Deposit Insurance Corporation ("FDIC") up to $0.1 million per
institution. At December 31, 2000 and 1999, the Company had cash accounts in
excess of FDIC insured limits.


F-10


KILROY REALTY CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


Recent accounting pronouncements--The Financial Accounting Standards Board
issued Statement of Financial Accounting Standards No. 133 "Accounting for
Derivative Instruments and Hedging Activities" ("SFAS 133") and Statement of
Financial Accounting Standards No. 138 "Accounting for Certain Derivative
Instruments and Certain Hedging Activities, an Amendment of FASB Statement No.
133." ("SFAS 138") in June 1998 and June 2000, respectively. SFAS 133 and SFAS
138 are effective for fiscal years beginning after June 15, 2000 and require
all derivatives to be recorded on the balance sheet at fair value. If the
derivative instrument qualifies as a hedge, depending on the nature of the
hedge, changes in fair value of the derivative will either be offset against
the change in fair value of the hedged assets, liabilities, or firm
commitments through earnings or recognized in other comprehensive income until
the hedged item is recognized in earnings. The ineffective portion of a
derivative's change in fair value will be immediately recognized in earnings.
The Company adopted SFAS 133 and 138 on January 1, 2001 and recorded a $2.0
million non-cash charge to other comprehensive income and a $1.4 million non-
cash charge to the income statement as the cumulative effect of change in
accounting principle.

In December 1999, the SEC issued Staff Accounting Bulletin No. 101,
"Revenue Recognition in Financial Statements" ("SAB 101"). In June 2000, the
SEC issued SAB 101B to defer the effective date for implementation of SAB 101
until the fourth quarter of fiscal 2000. SAB 101 summarizes certain of the
SEC's views in applying accounting principles generally accepted in the United
States of America to revenue recognition in financial statements. The adoption
of SAB 101 did not have a material impact on the Company's financial position
or results of operations.

3. Acquisitions, Dispositions, and Completed Development Projects

Acquisitions of Undeveloped Land

During the year ended December 31, 2000, the Company acquired 20 acres of
undeveloped land through two separate transactions from two unaffiliated third
parties for $15.5 million, consisting of $7.0 million in cash and the issuance
of an $8.5 million mortgage note payable due to one of the sellers. The $8.5
million mortgage note is payable upon the earlier of the successful completion
of infrastructure improvements to the undeveloped land that the seller is
obligated to perform, or December 31, 2003, the note's stated maturity.
Through December 31, 2000 the note accrued interest at 10.00% per annum. If
the infrastructure improvements are not completed by December 31, 2000, the
note will not accrue any additional interest and the principal balance of the
note will be reduced at the rate of $1,000 per day. As of December 31, 2000,
the infrastructure improvements were not completed. The Company currently
expects that the infrastructure improvements will be completed in the fourth
quarter of 2001.

During the year ended December 31, 1999, the Company consummated a series
of transactions to acquire 31 acres of undeveloped land for an aggregate
purchase price of approximately $16.3 million in cash and 119,460 common
limited partnership units of the Operating Partnership valued at approximately
$2.5 million based upon the closing share price of the Company's common stock
as reported on the New York Stock Exchange ("NYSE") at the time of
acquisition. The common limited partnership units were issued in connection
with the acquisition of three acres of undeveloped land located in San Diego,
California from The Allen Group (see Note 13).

During the first quarter of 1999, the Company acquired a 50% interest in 55
acres of undeveloped land in San Diego, California for $16.1 million and
184,172 common limited partnership units of the Operating Partnership valued
at $3.8 million based upon the closing share price of the Company's common
stock as reported on the NYSE at the time of acquisition. The undeveloped land
was acquired pursuant to an existing agreement executed by the Company and The
Allen Group in October 1997 that provided for the joint development of two
multi-phased office projects with approximately 1.1 million aggregate rentable
square feet over the next three years (see Note 13).

F-11


KILROY REALTY CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


Acquisitions of Operating Properties

In October 2000, the Company acquired a 25% tenancy-in-common interest in
office complex located in El Segundo, California from Kilroy Airport Imperial
Co. The complex encompasses approximately 366,000 aggregate rentable square
feet and is comprised of two office buildings and one parking structure. The
remaining 75% tenancy-in-common interest was acquired in January 2001 (see
Notes 13 & 19).

During the year ended December 31, 1999, the Company consummated a series
of transactions to acquire three office buildings and the 12.5% minority
interest in a three-building complex the Company owns in Diamond Bar,
California for an aggregate purchase price of approximately $28.2 million in
cash and 168,402 common limited partnership units of the Operating Partnership
valued at approximately $3.6 million based upon the closing share price of the
Company's common stock as reported on the NYSE at the time of acquisition. The
three office buildings contain approximately 176,900 aggregate rentable square
feet. The common limited partnership units were issued in connection with the
acquisition of two office buildings located in San Diego, California from
entities controlled by a senior executive officer of The Allen Group (see Note

7. Unsecured Line of Credit and Unsecured Term Facility

In November 1999, the Company increased its borrowing capacity and obtained
a new $400 million unsecured revolving credit facility (the "Credit Facility")
with a bank group lead by Morgan Guaranty Trust Company of New York and The
Chase Manhattan Bank, to replace its previous $350 million Credit Facility
which was scheduled to mature in February 2000. The Credit Facility bears
interest at a rate between LIBOR plus 1.13% and LIBOR plus 1.75% (8.26% and
7.56% at December 31, 2000 and 1999, respectively), depending upon the
Company's leverage ratio at the time of borrowing, and matures in November
2002. At December 31, 2000 and 1999, the Company had borrowings of $191
million and $228 million, respectively, outstanding under the Credit Facility.
Availability under the Credit Facility, was approximately $75.0 million at
December 31, 2000. The fee for unused funds ranges from 0.20% to 0.35%
depending on the Company's leverage ratios. The Company expects to use the
available borrowing capacity under the Credit Facility to finance development
expenditures and for general corporate uses.

In September 2000, the Company borrowed $100.0 million under an unsecured
debt facility from a bank group led by The Chase Manhattan Bank and Morgan
Guaranty Trust Company of New York. The $100.0 million facility, which matures
in September 2002 with two one-year extension options, requires monthly
interest-only payments based upon an annual interest rate between LIBOR plus
1.13% and LIBOR plus 1.75% (8.19% at December 31, 2000), depending upon the
Company's leverage ratio at the time of borrowing.

In January 2001, the Company entered into an interest rate swap agreement
with a total notional amount of $150 million to effectively limit interest
expense on the Company's floating rate debt during periods of increasing
interest rates. The agreement expires in November 2002, requires the Company
to pay fixed rate interest payments based on an interest rate of 5.48% and
receive floating rate interest payments based on one-month LIBOR.

In February 2000, the Company entered into an interest rate swap agreement
with a total notional amount of $150 million to effectively limit interest
expense on the Company's floating rate debt during periods of increasing
interest rates. The agreement, which expires in February 2002, requires the
Company to pay fixed rate interest payments based on an interest rate of 6.95%
and receive floating rate interest payments based on one-month LIBOR.

interest rates. The agreement cost $1.9 million, began in July 2000, had a
LIBOR based cap rate of 6.50%, and a contractual expiration date of January
2002. The Company terminated this cap agreement on January 2, 2001.

As of December 31, 1999, the Company was party to two interest rate cap

interest expense on the Company's floating rate debt during periods of
increasing interest rates. The agreements had LIBOR based cap rates of 6.50%
and expired in July 2000.

The Credit Facility and the $100.0 million facility contain covenants
requiring the Company to meet certain financial ratios and reporting
requirements. Some of the more restrictive covenants include a minimum debt
service coverage ratio, a maximum total liabilities to total assets ratio, a
maximum total secured debt to total assets ratio, a minimum cash flow to debt
service and fixed charges ratio, a minimum consolidated tangible net worth and
a limit of development activities as compared to total assets. The Company was
in compliance with all of the Credit Facility and the $100.0 million facility
covenants at December 31, 2000 and 1999.

Company's Board of Directors, and John B. Kilroy, Jr., the Company's President
and Chief Executive Officer. In addition, 1,739 of the 481,290 common limited
partnership units were owned by a Vice President of the Company (see notes 9
and 13). During the year ended December 31, 1999, 444,200 common limited
partnership units of the Operating Partnership, of which 440,000 common
limited partnership units were owned by John B. Kilroy, Sr., John B. Kilroy,

Operating Partnership received any proceeds from the issuance of the common
stock to the identified common limited partnership unitholders.

Preferred Unitholders

In December 1999, the Company issued 900,000 9.250% Series D Cumulative
Redeemable Preferred units, representing preferred limited partnership
interests in the Operating Partnership (the "Series D Preferred units"), with

contribution proceeds, less applicable transaction costs and expenses of

F-17


KILROY REALTY CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

$1.2 million, for the repayment of borrowings outstanding under the Credit
Facility. The Series D Preferred units, which may be called by the Operating
Partnership at a price equal to the liquidation value on or after December 9,
2004, have no stated maturity or mandatory redemption and are not convertible
into any other securities of the Operating Partnership. The Series D Preferred
units are exchangeable at the option of the majority of the holders for shares
of the Company's 9.250% Series D Cumulative Redeemable Preferred stock
beginning December 9, 2009, or earlier under certain circumstances.

As of December 31, 2000 and 1999, the Company had issued and outstanding
700,000 9.375% Series C Cumulative Redeemable Preferred units (the "Series C

limited partnership interests in the Operating Partnership with a liquidation
value of $50.00 per unit. The Series A and Series C Preferred units, which may
be called by the Operating Partnership at a price equal to the liquidation
value on or after November 24, 2003 and February 6, 2003, respectively, have
no stated maturity or mandatory redemption and are not convertible into any
other securities of the Operating Partnership. The Series A and Series C
Preferred Units are exchangeable at the option of the majority of the holders

unitholders, respectively.

Development LLCs

The Company became a 50% managing member in each of the Development LLCs in
March 1999 as a result of the acquisition of certain undeveloped land and the
simultaneous contribution of such land to the Development LLCs (see Notes 3
and 13). The Development LLCs are consolidated for financial reporting
purposes because the Company holds a 50% ownership interest combined with the
ability to control all significant development decisions.

9. Stockholders' Equity

The Company announced the approval of its share repurchase program in
December 1999, pursuant to which the Company is authorized to repurchase up to
an aggregate of 3.0 million shares of its outstanding common stock. During the
first quarter of 2000, the Company repurchased 1,999,300 shares of its common
stock in open market transactions for an aggregate repurchase price of $41.2
million, or $20.58 per share. The Company did not repurchase any shares of
common stock in the second, third and fourth quarters of 2000. During December
1999, the Company repurchased 265,000 shares in open market transactions for
an aggregate repurchase price of $5.4 million or $20.19 per share. Repurchases
during 2000 and 1999 were funded primarily through proceeds received from the
Company's dispositions, working capital and borrowings on the Company's Credit
Facility.

In June 2000, the Company's Compensation Committee, comprised of two
independent directors, granted 175,000 shares of restricted stock to certain
key employees, the grantees. All of the shares of restricted stock

F-18


KILROY REALTY CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

granted, which were sold for $0.01 per share, contain cliff-vesting provisions
such that the shares vest 100% on March 1, 2003. Compensation expense for the
restricted shares is calculated based upon the Company's closing share price
of $24.94 on the June 23, 2000 grant date, and is amortized on a straight-line
basis over the vesting period and included in general and administrative
expenses in the consolidated statements of operations. The restricted shares
have the same dividend and voting rights as common stock. The restricted
shares are included in the Company's calculation of weighted average
outstanding shares at December 31, 2000.

During 2000, 481,290 common limited partnership units of the Operating
Partnership were exchanged into shares of the Company's common stock. Of these
481,290 common limited partnership units, 364,200 common limited partnership
units were owned by Kilroy Industries, an entity owned by John B. Kilroy, Sr.,
the Chairman of the Company's Board of Directors and John B. Kilroy, Jr., the
Company's President and Chief Executive Officer. In addition, 1,739 of the
481,290 common limited partnership units, were owned by a Vice President of
the Company (see notes 8). During 1999, 444,200 common limited partnership
units of the Operating Partnership, of which 440,000 common limited
partnership units were owned by John B. Kilroy, Sr., John B. Kilroy, Jr., and
Kilroy Industries were exchanged into shares of the Company's common stock
(see Notes 8).

During 2000 and 1999, the SEC declared effective four registration
statements filed by the Company on Form S-3 which registered the potential
issuance and resale of up to a total of 4,672,902 shares of the Company's
common stock in exchange for 4,672,902 common limited partnership units of the
Operating Partnership previously issued in connection with certain 1997, 1998
and 1999 property acquisitions and the formation of the Operating Partnership.
The common limited partnership units may be exchanged at the Company's option
into shares of the Company's common stock on a one-for-one basis. Neither the
Company nor the Operating Partnership will receive any proceeds from the
issuance of the common stock resulting from any such exchange.

In September 1999, the SEC declared effective the Company's registration
statement on Form S-3 with respect to 1,000,000 shares of the Company's common
stock to be issued under the Company's Dividend Reinvestment and Direct
Purchase Plan (the "Plan"). The Plan, which is designed to provide the
Company's stockholders and other investors with a convenient and economical
method to purchase shares of the Company's common stock, consists of three
programs: the Dividend Reinvestment Program (the "DRIP"), the Cash Option
Purchase Plan (the "COPP"), and the Waiver Discount Plan (the "WDP"). The DRIP
provides existing common stockholders with the opportunity to purchase
additional shares of the Company's common stock by automatically reinvesting
all or a portion of their cash dividends. The COPP provides existing common
stockholders and other investors with the opportunity to purchase additional
shares of the Company's common stock by making optional cash purchases, at no
discount to market, between $100 to $5,000 and $750 to $5,000, respectively,
in any calendar month. The WDP provides existing common stockholders and other
investors with the opportunity to purchase additional shares of the Company's
common stock by making optional cash purchases, at a discount to market of up
to 2% of the average per share price reported on the NYSE, of greater than
$5,000 in any calendar month. The Plan acquires shares of the Company's common
stock from either new issuances directly from the Company, from the open
market or from privately negotiated transactions, except for shares acquired
under the WDP which are purchased only from previously unissued shares of
common stock. Participation in the Plan is entirely voluntary, and can be
terminated at any time. The Company intends to use the proceeds received from
the Plan, less transaction costs, for development and investment activities,
repayment of outstanding indebtedness and general corporate uses. As of
December 31, 2000, there have been no previously unissued shares acquired
under the Plan.

In May 1999, the Company filed a registration statement on Form S-8 with
the SEC that registered the potential issuance and resale of up to 1,500,000
shares of the Company's common stock issuable to the Company's employees and
directors under the 1997 Stock Option and Incentive Plan (see Note 11).

11. Employee Retirement and Stock Option and Incentive Plans

Retirement Savings Plan

Effective November 1, 1997, the Company adopted a retirement savings plan
designed to qualify under Section 401(k) of the Internal Revenue Code (the
"401(k) Plan"). The 401(k) Plan allows participants to defer up to twenty
percent of their eligible compensation on a pre-tax basis, subject to certain
maximum amounts allowed by the Internal Revenue Code. The 401(k) Plan provides
for a matching contribution by the Company in an amount equal to fifty-cents
for each one dollar of participant contributions up to a maximum of five
percent of the participant's annual salary. Participants vest immediately in
the amounts contributed by the Company. Employees of the Company are eligible
to participate in the 401(k) Plan when they meet certain requirements
concerning minimum period of credited service. For the years ended December
31, 2000, 1999, and 1998, the Company contributed $0.2 million, $0.1 million,
and $0.1 million respectively to the 401(k) Plan.

Stock Option and Incentive Plan

The Company has established a stock option and incentive plan (the "Stock
Plan") for the purpose of attracting and retaining officers and key employees,
under which restricted shares or stock options may be granted. The Stock Plan
authorizes the issuance of 3,000,000 shares of common stock of the Company. At
December 31, 2000 and 1999, an aggregate of 1,608,140 and 1,003,000 options
were exercisable for shares of the Company's common stock at a weighted
average exercise price of $23.20 and $23.24, respectively. The weighted
average exercise price of the options outstanding at December 31, 2000 and
1999 was $23.13 and $23.07, respectively, with a weighted average remaining
contractual life of 7.1 years and 8.0 years, respectively. Stock options vest
at 33 1/3% per year over three years beginning on the first anniversary date
of the grant and are exercisable at the market value on the date of the grant.
The term of each option is ten years from the date of the grant.

Restricted stock is subject to restrictions determined by the Company's
Compensation Committee. The Compensation Committee, comprised of two Directors
who are not officers of the Company, determines compensation, including awards
under the Stock Plan, for the Company's executive officers. Restricted stock
has the same dividend and voting rights as common stock and is issued and
outstanding. In connection with the Company's initial public offering in
January 1997, 100,000 shares of restricted stock were issued to an executive
officer of the Company for a price of $1,000 and vest 20% per year over a
five-year period. Compensation expense is determined by reference to the
market value of the Company's common shares and is being amortized on a
monthly basis over the five-year vesting period. Compensation expense relating
to these shares was approximately $0.4 million for the year ended December 31,
2000, and approximately $0.5 million for the years ended December 31, 1999 and
1998. On June 23, 2000, the Company granted 175,000 shares of restricted stock
to certain key employees, the grantees. The shares of restricted stock contain
stock-vesting provisions such that the shares vest 100% on March 1, 2003.
Compensation expense for the restricted shares is calculated based on the
closing per share price of $24.94 on the June 23, 2000 grant date and is
amortized on a straight-line basis over the vesting period. The compensation
expense related to this restricted stock grant was approximately $0.8 million
for the year ended December 31, 2000. In the event all of the grantees remain
with the Company until the March 1, 2003 stock-vesting date, non-cash
compensation expense related to this grant will be recorded at a rate of
approximately $1.6 million per year. Restricted shares are included in the
Company's outstanding shares at December 31, 2000.

The Company's stock option activity is summarized as follows:

Outstanding at December 31, 1997................. 1,185,000 $23.80

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

The Company has adopted the disclosure-only provisions of Statement of
Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" ("SFAS No. 123") and will continue to use the intrinsic value
based method of accounting prescribed by Account Practice Bulletin opinion No.
25, "Accounting for Stock Issued to Employees" and FASB Interpretation No. 44,
"Accounting for Certain Transactions Involving Stock Compensation."
Accordingly, no compensation cost has been recognized for the options granted
under the Stock Plan. Had compensation cost for the Company's Stock Plan been
determined based on the fair value at the grant date consistent with the
provisions of SFAS No. 123, the Company's net income and net income on a per
share basis would have been adjusted to the pro forma amounts indicated below:



Year Ended December 31,
-----------------------
2000 1999 1998
------- ------- -------
(in thousands, except
per share amounts)

Net income:
As reported....................................... $46,846 $39,895 $38,822

Net income per common share--basic:

Net income per common share--diluted:
As reported....................................... 1.75 1.44 1.43
Pro forma......................................... $ 1.67 $ 1.34 $ 1.38


The fair value of each option grant issued in 2000, 1999, and 1998 is
estimated on the date of grant using the Black-Scholes option-pricing model
with the following weighted average assumptions (amounts shown as 2000, 1999,
and 1998, respectively): (a) dividend yield of 6.90%, 6.73%, and 6.31%, (b)
expected volatility of the Company's stock of 26.2%, 27.0%, and 26.2%, (c)
risk free interest rate of 5.18%, 6.64%, and 4.73%, and (d) expected option
life of seven years. The effects of applying SFAS No. 123 may not be
representative of the effects on disclosed pro forma net income for future
years because options vest over several years and additional awards can be
made each year.

12. Commitments and Contingencies

Operating leases--The Company has noncancelable ground lease obligations on
the SeaTac Office Center in Seattle, Washington expiring December 2032, with
an option to extend the lease for an additional 30 years; 12312 W. Olympic

October 2043. On the Kilroy Airport Center and the SeaTac Office Center ground
leases, rentals are subject to adjustments every five years based on the
Consumer Price Index. On the 12312 W. Olympic Boulevard ground lease, rentals
are subject to adjustments every year based on the Consumer Price Index.
Subsequent to December 31, 2000, the Company acquired the fee interest in the
land at 9455 Towne Center in San Diego, California and the ground lease was
terminated.

Purchase agreement--In connection with an agreement signed with The Allen
Group in October 1997, the Company has agreed to purchase one office property
encompassing 128,000 rentable square feet, subject to the property meeting
certain occupancy thresholds and other tenancy requirements. The purchase
price for this property will be determined at the time of acquisition based on
the net operating income at that time. The Company expects that in the event
that this acquisition does occur, it would be financed with borrowings under
the Credit Facility and the issuance of common limited partnership units of
the Operating Partnership.

Litigation--Neither the Company nor any of the Company's properties are
presently subject to any material litigation nor, to the Company's knowledge,
is any material litigation threatened against any of them which if determined
unfavorably to the Company would have a material adverse effect on the
Company's cash flows, financial condition or results of operations. The
Company is party to litigation arising in the ordinary course of business,
none of which if determined unfavorably to the Company, individually or in the
aggregate, is expected to have a material adverse effect on the Company's cash
flows, financial condition or results of operations.

Environmental Matters--The Company follows the policy of monitoring its
properties for the presence of hazardous or toxic substances. While there can
be no assurance that a material environmental liability does not exist, the
Company is not currently aware of any environmental liability with respect to
the properties that would have a material effect on the Company's financial
condition, results of operations and cash flows. Further, the Company is not
aware of any environmental liability or any unasserted claim or assessment
with respect to an environmental liability that the Company believes would
require additional disclosure or the recording of a loss contingency.

13. Related-Party Transactions

Note Receivable from Related Party

In May 2000, the Company initiated actions that put it in a position to
potentially acquire the fee interest in a three building office complex
located in El Segundo, California from Kilroy Airport Imperial Co. ("KAICO"),
a partnership owned by John B. Kilroy, Sr., the Company's Chairman of the
Board of Directors, John B. Kilroy, Jr. the Company's President and Chief
Executive Officer, and certain other Kilroy family members. The complex, which
encompasses approximately 366,000 aggregate rentable square feet, is comprised
of two office buildings and a parking structure. One of the office buildings
is occupied by Hughes Space & Communications Company ("Hughes") and the other
office building is vacant.

On May 1, 2000, the Company purchased a non-recourse note receivable
secured by the aforementioned office complex with an outstanding principal
balance of $60.8 million, accrued interest of $10.2 million, an annual
interest rate of 9.63%, and a maturity date of February 1, 2005 from an
institutional lender for $45.3 million. At the time of the acquisition, KAICO
was in payment default under the terms of the note. The

F-23


KILROY REALTY CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

Company recorded its investment in the impaired note at the $45.3 million
purchase price and recorded no additional impairment allowance since the
Company believes that the purchase price of the note is less than the fair
market value of the complex securing it as supported by independent, third-
party appraisals. The Company and KAICO also entered into agreements whereby
the Company agreed to pay KAICO approximately $3.3 million for the
reimbursement of expenditures incurred by KAICO on the complex since 1997 and
for the modification of an existing option that the Company holds to purchase
the complex. The acquisition of the note was funded with borrowings under the
Company's revolving credit facility.

As a result of the acquisition of the note, the Company received
approximately $2.7 million which was recorded as interest income. In October
2000, the Company and KAICO agreed to modify the terms of the note to write
down the principal value and accrued interest to $45.3 million. In connection
with the modification of the note in October 2000, a wholly-owned subsidiary
of the Company acquired a 25% tenancy-in-common interest in the complex from
KAICO subject to 25% or $11.3 million of the $45.3 million note in exchange
for 1,133 common units of the Operating Partnership valued at approximately
$30,000 based upon the closing share price of the Company's common stock as
reported on the New York Stock Exchange. During the fourth quarter of 2000 the
Company recorded approximately $0.2 million as other income related to its
equity in earnings from its 25% tenancy-in-common interest. The tenancy-in-
common interest is included as an investment in unconsolidated real estate in
the consolidated balance sheet as of December 31, 2000.

On January 9, 2001, the Operating Partnership acquired the remaining 75%
tenancy-in-common interest in the complex from KAICO for $33.4 million in
cash. KAICO concurrently used the proceeds to pay off the outstanding note
receivable balance and related accrued interest to the Company.

Acquisitions

In March 1999, the Company acquired three office buildings in San Diego,
California from entities controlled by a senior executive officer of The Allen
Group in exchange for $17.5 million in cash and 168,402 common units of the
Operating Partnership valued at approximately $3.6 million based upon the
closing share price of the Company's common stock as reported on the NYSE at
the time the property was acquired (see Note 3). The office property, which
contains approximately 126,000 aggregate rentable square feet and is 100%
leased through February 2014, was acquired pursuant to an existing agreement
executed by the Company and The Allen Group in October 1997, prior to The
Allen Group becoming a related party of the Company. In connection with this
anticipated transaction, the Company entered into an agreement in May 1998 to
loan $2.3 million to a limited liability company controlled by a senior
executive officer of The Allen Group to finance tenant improvements to this
property. The $2.3 million balance of the note, which was secured by the
pledge of membership interests in the limited liability company, and the
related interest, which accrued at a rate of Prime plus 1.00%, was repaid to
the Company in connection with the acquisition. A former Executive Vice
President of the Company received 98,476 of the total 168,402 common limited
partnership units issued in connection with the acquisition. The acquisition
was based upon terms that the Company believes were comparable to terms
obtainable from third-parties based on arm's-length negotiations.

In February 1999, the Company acquired three acres of undeveloped land in
San Diego, California from entities controlled by a senior executive officer
of the Allen Group in exchange for $0.4 million in cash and 119,460 common
limited partnership units of the Operating Partnership valued at approximately
$2.5 million based upon the closing share price of the Company's common stock
as reported on the NYSE at the time the undeveloped land was acquired (see
Note 3). A former Executive Vice President of the Company received 76,896 of
the total 119,460 common limited partnership units issued in connection with
the acquisition. The acquisition was based upon terms that the Company
believes were comparable to terms obtainable from third-parties based on
arm's-length negotiations.


F-24


KILROY REALTY CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

During the first quarter of 1999, the Company acquired a 50% interest in 55
acres of undeveloped land in San Diego, California in exchange for $16.1
million and 184,172 common limited partnership units of the Operating
Partnership valued at approximately $3.8 million based upon the closing share
price of the Company's common stock as reported on the NYSE at the time the
undeveloped land was acquired (see Note 3). The interest in the undeveloped
land was acquired pursuant to an existing agreement executed by the Company
and The Allen Group in October 1997 that provided for the joint development of
two office projects with approximately 1.1 million aggregate rentable square
feet over the next three years. Both the Company and The Allen Group
contributed their respective 50% interests in the undeveloped land to the two
Development LLCs. In connection with this anticipated transaction, the Company
entered into an agreement in May 1998 to loan up to $8.5 million to a limited
partnership controlled by a senior executive officer of The Allen Group to
finance infrastructure improvements on the undeveloped land. The $8.5 million
balance of the note, which was secured by the undeveloped land, was assumed by
one of the Development LLCs. The related interest, which accrued at a rate of
LIBOR plus 1.85%, was paid to the Company by the limited partnership. A former
Executive Vice President of the Company received 69,694 of the total 184,172
common limited partnership units issued in connection with the acquisition.
The acquisition was based upon terms that the Company believes were comparable
to terms obtainable from third-parties based on arm's-length negotiations.

In March 1999, the Company acquired construction materials for its Kilroy
Airport Center, Long Beach development project from a partnership controlled
by John B. Kilroy Sr. and John B. Kilroy, Jr. for approximately $4.3 million.
The acquisition of the construction materials was based upon terms that the
Company believes were comparable to terms obtainable from third-parties based
on arm's-length negotiations.

Other Transactions

Pursuant to management agreements, the Operating Partnership provided
management and leasing services during 2000, 1999 and 1998, and KSI provided
development services during 1998, with respect to two properties, each of
which is beneficially owned by John B. Kilroy, Sr. and John B. Kilroy, Jr. The
Operating Partnership recorded fees of $0.1 million, $0.1 million and $0.2
million for the years ended December 31, 2000, 1999, and 1998, respectively,
relating to the management and leasing services. KSI recorded fees of $0.1
million for the year ended December 31, 1998 related to the development
services.

In October 1997, KSI entered into a management agreement to manage the
development of certain properties owned by entities under the common control
of a senior executive officer of The Allen Group. At December 31, 2000 and
1999, KSI had a receivable balance of $.2 million and $0.3 million for
management fees earned, respectively.

At December 31, 2000, other assets include a note receivable and accrued
interest totaling $0.3 million due from a Senior Vice President of the
Company. The note bears interest at 8%, matures in July 2005 and is secured by
real property owned by the officer.

14. Fair Value of Financial Instruments

The carrying amounts of the Company's cash and cash equivalents, restricted
cash and accounts payable approximate fair value due to their short-term
maturities. The carrying amounts of the Company's variable rate secured debt
and unsecured term facility, outstanding borrowings on the Credit Facility,
and note receivable from related party approximate fair value since the
interest rates on these instruments are equivalent to rates currently offered
to the Company.

F-25


KILROY REALTY CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


For fixed rate secured debt, the Company estimates fair value by using
discounted cash flow analyses based on borrowing rates for similar types of
borrowing arrangements. The fair value of the Company's fixed rate secured
debt was $257 million and $225 million at December 31, 2000 and 1999,
respectively.

For the Series A, Series C, and Series D Preferred units, the Company
estimates fair value by using discounted cash flow analyses based on borrowing
rates for similar types of fixed rate financial instruments. The fair value of
the Series A, Series C and Series D Preferred units was $142 million and $146
million at December 31, 2000 and 1999, respectively.

For interest rate cap agreements and interest rate swap agreements, the
Company estimates fair value by using available market information and
appropriate valuation techniques. At December 31, 2000 and 1999, the Company's
derivative instruments had a negative fair value of $1.9 million and zero,
respectively.

15. Segment Disclosure

The Company's reportable segments consist of the two types of commercial
real estate properties for which management internally evaluates operating
performance and financial results: Office Properties and Industrial
Properties. The Company also has certain corporate level activities including
legal, accounting, finance, and management information systems which are not
considered separate operating segments.

The Company evaluates the performance of its segments based upon net
operating income. Net operating income is defined as operating revenues
(rental income, tenant reimbursements and other property income) less property
and related expenses (property expenses, real estate taxes, and ground leases)
and excludes interest income and expense, depreciation and amortization, and
corporate general and administrative expenses. The accounting policies of the
reportable segments are the same as those described in the Company's summary
of significant accounting policies (see Note 2). There is no intersegment
activity.

16. Earnings Per Share

Basic earnings per share is computed by dividing net income by the
weighted-average number of common shares outstanding for the period. Diluted
earnings per share is computed by dividing net income by the sum of the
weighted-average number of common shares outstanding for the period plus the
assumed exercise of all dilutive securities. The Company does not consider
common limited partnership units of the Operating Partnership to be dilutive
securities since the exchange of common limited partnership units into common
stock is on a one for one basis and would not have any effect on diluted
earnings per share. The following table reconciles the numerator and
denominator of the basic and diluted per-share computations for net income for
the three years ended December 31, 2000, 1999 and 1998:
