PART I

ITEM 1. BUSINESS

General

Kilroy Realty Corporation (the "Company") develops, owns, and operates
office and industrial real estate, primarily in Southern California. 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, 1999, the Company's portfolio of stabilized operating
properties was comprised of 84 office buildings encompassing approximately 6.1
million rentable square feet (the "Office Properties") and 87 industrial
buildings encompassing approximately 6.5 million rentable square feet (the
"Industrial Properties" and, together with the Office Properties, the
"Properties"). The Company's stabilized portfolio consists of all of the
Company's Office and Industrial Properties, excluding projects recently
developed by the Company that have not yet reached 95% occupancy ("lease-up"
properties) and projects currently under construction or in pre-development.
As of December 31, 1999, the Office Properties were approximately 96.4% leased
to 395 tenants and the Industrial Properties were approximately 96.9% leased
to 258 tenants. As of December 31, 1999, the Company had seven office
buildings under construction which when completed are expected to encompass an
aggregate of approximately 861,500 rentable square feet. The Company did not
have any properties in lease-up at December 31, 1999 since all of the
properties developed and completed by the Company during 1999 and 1998,
encompassing an aggregate of approximately 862,400 and 1.1 million rentable
square feet, respectively, stabilized during 1999. All but 15 of the Company's
properties are located in Southern California. All of the Company's
development projects are located in Southern California.

The Company owns its interests in all of its 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, 1999, it owned an approximate 86.8%
general partnership interest. The remaining 13.2% 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 151 of the Company's 171 properties. The remaining properties, other than
two properties which are owned by the Operating Partnership through KR-Carmel
Partners and KR-Gateway Partners, two development LLCs (the "Development
LLCs") in which the Company owned a 50% managing interest at December 31,
1999, 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.

The Company's strategy is to own, develop, acquire, lease and manage Class
A suburban office and industrial real estate properties in select locations in
key suburban submarkets, primarily in Southern California, that the Company
believes have strategic advantages compared to neighboring submarkets.

At December 31, 1999, the Company's ten largest office tenants represented
approximately 25.0% of total annual base rental revenues, defined as
annualized monthly contractual rents from existing tenants at December 31,
1999 determined in accordance with generally accepted accounting principles,
and its ten largest industrial tenants represented approximately 8.7% of total
annual base rental revenues. Of this amount, its largest tenant, Hughes
Electronics Corporation's Space and Communications Company ("Hughes Space and
Communications"), currently leases approximately 405,300 rentable square feet
of office space under five separate leases, representing approximately 6.4% of
the Company's total annual base rental revenues at

December 31, 1999. The base periods for 95.6% of the Hughes Space and
Communications leases expire in January and July 2004. The base periods for
the remaining Hughes Space and Communications leases expire during the period
from November 2001 through December 2001.

The Company's five largest office tenants, based on annualized base rental
revenues, include: Hughes Space and Communications, a tenant since 1984 which
is engaged in high-technology commercial activities including satellite
development and related applications such as DirecTV; The Boeing Company;
Epson America, Inc.; Epicor Software Corporation; and Intuit, Inc. The
Company's five largest industrial tenants, based on annualized base rental
revenues, include: Mattel, Inc.; Celestica California, Inc.; Natural
Alternatives International, Inc.; OmniPak (d.b.a. Raven Industries); and Mazda
Motor of America, Inc. (See Item 2: Properties--Tenant Information for further
discussion on the Company's tenant base.)

Business and Growth Strategies

Growth Strategies. The Company believes that a number of factors will
enable it to continue to achieve growth in Funds From Operations, as defined
by the National Association of Real Estate Investment Trusts, 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 properties; (iii) 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; (iv) the Company's substantial development
pipeline established over the past several years; and (v) the Company's access
to development and leasing opportunities as a result of its significant
relationship with large Southern California corporate tenants, municipalities
and landowners and the Company's 50-year presence in the Southern California
market. Management believes that the Company is well positioned to capitalize
on existing opportunities because of its extensive experience in certain of
its submarkets, its seasoned management team and its proven ability to
acquire, develop, lease and efficiently manage office and industrial
properties.

Operating Strategies. The Company focuses on enhancing growth in Funds From
Operations, from its properties by: (i) maximizing cash flow from the
properties through active leasing and early renewals, increasing contractual
base rent to current market levels as leases expire and effective property
management; (ii) managing operating expenses through the use of internal
management, leasing, marketing, financing, accounting, legal administration
and construction management functions; (iii) maintaining and developing long-
term relationships with a diverse tenant group; (iv) attracting and retaining
motivated employees by providing financial and other incentives to meet the
Company's operating and financial goals; and (v) continuing to emphasize
capital improvements to enhance the properties' competitive advantages in
their respective markets and improve the efficiency of building systems.

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 three target market regions, Los
Angeles, Orange and San Diego Counties. The Company's committed and future
development pipeline (including projects held through joint venture
arrangements) can support future development of over 2.8 million rentable
square feet of office space at a total budgeted cost of over $550 million over
the next four to five years. The Company's strategy is to maintain a
disciplined approach to development by focusing on pre-leasing, phasing and
cost control. During 1999 and 1998, the Company completed 17 buildings
encompassing an aggregate of approximately 2.0 million rentable square feet at
an aggregate cost of approximately $171 million. As of December 31, 1999, the
Company had seven office buildings under construction which when completed are
expected to encompass an aggregate of approximately 861,500 rentable square
feet at a total budgeted cost of approximately $174 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.

Financing Policies. The Company's financing policies and objectives are
determined by the Company's Board of Directors. The Company presently intends
to 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, 1999, total debt constituted approximately 38.8% of the total market
capitalization of the Company. 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.

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 of
the hazardous materials. Government investigations and remediation actions may
have substantial costs and the presence of hazardous wastes on a property
could result in personal injury or similar claims by private plaintiffs. For
instance, if asbestos-containing materials and other hazardous or toxic
substances were found on the Company's properties, third parties might seek
recovery from the Company for personal injuries resulting from the existence
of those substances. As of December 31, 1999, 29 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, 1999,
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 conducted Phase I or similar environmental site assessments on all
of the Company's properties. 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 some 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. 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 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, that all of its properties are in good condition.
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.

Employees

As of March 10, 2000, the Company, through the Operating Partnership and
Kilroy Services, Inc., an unconsolidated subsidiary of the Company ("KSI"),
employed 130 persons. Of the Company's total 130 employees, approximately 40
are employed as on-site building employees who provide services for the
Company's properties. The Company, the Operating Partnership and KSI believe
that relations with their employees are good.

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, fee development activities, sources of
growth, planned development and expansion of owned or leased property, capital
requirements, compliance with contractual obligations 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 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, 1999, 86.5% of the aggregate square footage of the
Company's stabilized portfolio and 87.9% 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.

The Company's significant 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; and the Company's default under
one mortgage loan with cross default provisions could result in a default on
other indebtedness. If any one 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, 1999, the Company had $554 million
aggregate principal amount of indebtedness, $4.8 million of which is due prior
to December 31, 2000. The Company's total debt represented 38.8% of its total
market capitalization at December 31, 1999.

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, occupancy rates in the Company's El Segundo and
Long Beach office property portfolios at December 31, 1999 were 99.0% and
95.6%, respectively, in comparison to 86.4% and 86.5%, respectively, for the
El Segundo and Long Beach office submarkets in total. In addition, the
occupancy rate in the Company's Anaheim industrial property portfolio at
December 31, 1999 was 100.0% in comparison to 94.2% for the Anaheim industrial
property 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 uninsured losses such as loss from riots or acts of God. Some of
the Company's policies, like those covering losses due to floods, are insured
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
deductions which management believes are commercially reasonable. As of
December 31, 1999, 81 of the Office Properties aggregating 5.6 million square
feet (representing 44.5% of the Company's stabilized portfolio based on
aggregate square footage and 64.4% based on annualized base rent) were located
in areas known to be subject to earthquakes. As of December 31, 1999, 75 of
the Company's Industrial Properties aggregating 5.3 million square feet
(representing 42.0% of the Company's stabilized portfolio based on aggregate
square footage and 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. Property development involves the following significant risks: the
Company may be unable to obtain construction financing on favorable terms; the
Company may be unable to obtain permanent financing at all or on advantageous
terms if development projects are financed through construction loans; 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; and
the Company may lease the developed properties at below expected rental

rates. For example, one of the Company's development projects was completed
three months later than initially projected, resulting in a corresponding
delay in the commencement of leasing activity at the particular property. The
delay was attributable to bad weather conditions which inhibited construction
during the "El Nino" climate condition which ran from 1997 through 1998. In
addition, during the fourth quarter of 1998, the Company withdrew its
participation from a master planned commercial development prior to the
commencement of construction. If any one 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.

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
1.5 million aggregate rentable square feet of rental space located on these
leased parcels. 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 expire 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.

The Company depends on significant tenants. At December 31, 1999, the
Company's ten largest office tenants represented approximately 25.0% of total
annual base rental revenues and its ten largest industrial tenants represented
approximately 8.7% of total annual base rental revenues. Of this amount, its
largest tenant, Hughes Space and Communications, currently leases
approximately 405,300 rentable square feet of office space, representing
approximately 6.4% of the Company's total annual base rental revenues. 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, 1999, the Company derived 98.0% 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, its tenants could file for
bankruptcy protection in the future.

The Company may be unable to renew leases or re-let space as leases
expire. As of December 31, 1999, leases representing 11.2% and 14.2% of the
square footage of the Company's properties will expire in 2000 and 2001. 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 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. Limitations in
the Internal Revenue Code and related Treasury Regulations applicable to REITs
may also limit the Company's ability to sell its 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 pay
distributions to stockholders.

KSI is subject to tax liabilities on net income which reduces the Company's
cash flow. KSI is subject to federal and state income tax on its taxable
income at regular corporate rates. Any federal, state or local income taxes
that KSI must pay will reduce the cash available for distribution to the
Operating Partnership and, ultimately, to the Company's stockholders.

The Company cannot depend upon distributions from KSI because its business
is not controlled by the Company. The Company has set up the following
structure to comply with the REIT asset tests that restrict its ability to own
shares of other corporations: the Operating Partnership owns 100% of the non-
voting preferred stock of KSI, representing approximately 95.0% of its
economic value; and 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, own all of the outstanding voting common stock of KSI,
representing approximately 5.0% of its economic value. The Company receives
substantially all of the economic benefit derived from KSI's business by
virtue of the dividends that the Company receives from its investment in the
preferred stock. However, the Company cannot influence KSI's operations, elect
its directors, appoint its officers, or require its Board of Directors to
declare and pay a cash dividend on the nonvoting preferred stock owned by the
Operating Partnership. As a result, KSI may make decisions or pursue business
policies which could 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.

KSI may be adversely affected by the Company's REIT status. Changes in the
requirements for REIT qualification may in the future limit the Company's
ability to receive increased distributions from the fee development operations
and related services offered by KSI.

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
unitholders, including the Company, because of the common 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. 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 are engaged in competitive real estate
activities. The Company owns four office buildings and four industrial
buildings in the El Segundo submarket. 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, own controlling interests in partnerships
which own a complex of three office buildings in the same submarket. The
Operating partnership manages the complex pursuant to a management agreement
on market terms. Policies adopted by the Company's Board of Directors to
minimize this conflict, including the requirement that John B. Kilroy, Sr. and
John B. Kilroy, Jr. enter into non-competition agreements with the Company,
may not eliminate their influence over transactions involving these competing
properties.

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 2,158,639 shares of the Company's common
stock and currently vested options to purchase an aggregate of 350,000 shares
of common stock, representing a total of approximately 9.02% of the total
outstanding shares of common stock as of December 31, 1999. 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
already 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 already 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.

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. 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,
excluding capital gains. In addition, legislation, new regulations,
administrative interpretations or court decisions may adversely affect the
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 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. 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. To qualify as a REIT, the
Company generally must distribute to its stockholders at least 95% of the
Company's net taxable income each year, excluding capital gains. 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. 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, 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 acquisition 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.

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, 1999, 27,808,410 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: 4,228,702 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; 2,900,000 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 27,808,410 shares of
common stock presently outstanding, all but 40,000 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, 1999, the Company's portfolio of stabilized operating
properties was comprised of 84 Office Properties encompassing approximately
6.1 million rentable square feet and 87 Industrial Properties encompassing
approximately 6.5 million rentable square feet. The Company's stabilized
portfolio consists of all of the Company's Office and Industrial Properties,
excluding projects recently developed by the Company that have not yet reached
95% occupancy ("lease-up" properties) and projects currently under
construction or in pre-development. As of December 31, 1999, the Office
Properties were approximately 96.4% leased to 395 tenants and the Industrial
Properties were approximately 96.9% leased to 258 tenants. All but 15 of the
Company's properties are located in Southern California.

As of December 31, 1999, the Company had seven office buildings under
construction which when completed are expected to encompass an aggregate of
approximately 861,500 rentable square feet. The Company did not have any
properties in lease-up at December 31, 1999 since all of the properties
developed and completed by the Company during 1999 and 1998 stabilized during
1999. 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, 1999, the Company
managed all of its 84 Office Properties and 80 of its 87 Industrial Properties
through internal property managers.

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, 1999. 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 three
buildings located at 3579 Valley Center Drive and 5005/5010 Wateridge Vista
Drive in which the Company owns a 50% interest through the Development LLCs,
and the five office properties located at Kilroy Airport Center, Long Beach,
three office properties located at the SeaTac Office Center, one office
property located at 2100 Colorado Blvd. in Santa Monica, California and one
office property located at 9455 Towne Center Drive in San Diego, California,
each of which are held subject to leases for the land on which the properties
are located expiring in 2035, 2062, 2065 and 2043 (assuming the exercise of
the Company's options to extend such leases), respectively.

The Company pays distributions to common stockholders on or about the 10th
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 fiscal year 1999, the Operating Partnership issued 472,034 common
units of the Operating Partnership, valued by the Company at approximately
$9.9 million 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
entities controlled by Richard S. Allen, a former member of the Company's
Board of Directors, in partial consideration for the contribution of certain
properties and undeveloped land to the Operating Partnership. A former
Executive Vice President of the Company received 245,066 of the total 472,034
common units. The common units become convertible into shares of the Company's
common stock, on a one-for-one basis, one year after issuance date. The common
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.

During the fourth quarter of fiscal year 1999, the Company issued 900,000
9.250% Series D Cumulative Redeemable Preferred units, representing limited
partnership interests in the Operating Partnership with a liquidation value of
$50.00 per unit, in exchange for a gross contribution to the Operating
Partnership of $45.0 million. 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 ten years
from the date of issuance, or earlier under certain circumstances. The Series
D Cumulative Redeemable Preferred 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.

During 1999, the Company issued 442,200 shares of common stock upon the
conversion of 442,200 common units of the Operating Partnership by limited
partners. The issuance of the common shares on a one-for-one basis was made
pursuant to the terms set forth in the partnership agreement of the Operating
Partnership. The shares of common stock were issued in a transaction not
requiring registration under federal securities laws pursuant to Section 4(2)
of the Securities Act of 1933.

(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, 1995 and 1994 gains on extinguishment of debt; and
in 1999, 1998 and 1997 non-cash compensation. Further, in 1996 and 1995,
non-recurring items (sale of air rights and 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, 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 and the Kilroy Group. 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 related notes thereto. 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. You are cautioned not to
place undue reliance on these forward-looking statements.

Overview and Background

The Company, which develops, owns, and operates 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 86.8% general partnership interest in the
Operating Partnership as of December 31, 1999 and 1998.

The Company's revenue is derived primarily from rental income, including
tenant reimbursements. The Company's revenue growth in 1999 was due primarily
to a full year of operating results from $254 million in acquisitions
completed in 1998 and operating results from $171 million of development
projects completed by the Company in 1998 and 1999. While a significant
portion of the Company's revenue growth in 1999 and most of the Company's
revenue growth in 1998 and 1997 was due to the acquisition of $792 million of
properties in aggregate during the three-year period, the market for property
acquisitions continues to be competitive. As a result, management believes
that the most significant part of the Company's revenue growth over the next
two to three years will come from its substantial development pipeline of over
2.8 million rentable square feet of office space. Management also believes
that continued improvement of the real estate market in the Company's
principal markets and the continued economic expansion of Southern California
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 higher lease rates,
approximately 1.5 million square feet of office space and 1.6 million square
feet of industrial space currently subject to leases expiring during the next
two years. In addition, the Company intends to continue its leadership as a
low cost operator through integrated operations and disciplined cost
management.

Results of Operations

During the year ended December 31, 1999, the Company acquired three office
buildings encompassing 176,900 aggregate rentable square feet for an aggregate
acquisition cost of $30.6 million and disposed of five office and five
industrial buildings encompassing 113,700 and 335,800 aggregate rentable
square feet, respectively, for an aggregate sales price of $22.6 million.
During the year ended December 31, 1998, the Company acquired 25 office and 16
industrial buildings encompassing 1.4 million and 674,000 aggregate rentable
square feet, respectively, for an aggregate acquisition cost of $254 million.
Operating results for acquired properties are included in the consolidated
financial statements of the Company subsequent to their respective acquisition
dates.

During the year ended December 31, 1999, the Company completed the
development of six office and four industrial buildings encompassing an
aggregate of 472,200 and 390,200 rentable square feet, respectively. During
the year ended December 31, 1998, the Company completed the development of one
office and six industrial buildings encompassing an aggregate of 78,000 and
1.0 million rentable square feet, respectively. All of the aforementioned
development projects completed by the Company during 1999 and 1998 were
included in the Company's portfolio of stabilized operating properties at
December 31, 1999. The Company's stabilized portfolio consists of all of the
Company's Office and Industrial Properties, excluding properties recently
developed by the

Company that have not yet reached 95.0% occupancy ("lease-up" properties) and
projects currently under construction or in pre-development. The Company did
not have any lease-up properties at December 31, 1999 since all of the
development projects completed during 1998 and 1999 stabilized during 1999. At
December 31, 1999, the Company had seven office buildings under construction
which when completed are expected to encompass an aggregate of approximately
861,500 rentable square feet.

As a result of the properties acquired and developed by the Company
subsequent to December 31, 1998, net of the effect of properties disposed of
during 1999, rentable square footage in the Company's portfolio of stabilized
operating properties increased approximately 868,000 rentable square feet, or
7.4%, to 12.6 million rentable square feet at December 31, 1999 compared to
11.8 million rentable square feet at December 31, 1998. As of December 31,
1999, the Company's portfolio of stabilized operating properties was comprised
of 84 Office Properties encompassing 6.1 million rentable square feet and 87
Industrial Properties encompassing 6.5 million rentable square feet. The
stabilized portfolio occupancy rate at December 31, 1999 was 96.7%, with the
Office and Industrial Properties 96.4% and 96.9% occupied, respectively, as of
such date.

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 five 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 3.4% 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 3.7% increase in net
operating income for the Core Office Properties.

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, $3.4 million was generated by the industrial
buildings acquired during 1998 and 1999, net of the effect of the five
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 $0.5 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 1.8%
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 of 1.0% 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, $1.1 million was
attributable to the Net Industrial Acquisitions and the Industrial Development
Properties. The remaining $0.3 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 $0.5
million in property expenses attributable to the Net Industrial Acquisitions
and the Industrial Development Properties was offset by a decrease of $0.3
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 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, $8.0 million was generated by the Net Industrial Acquisitions and
the Industrial Development Properties. The remaining increase of $0.8 million
was generated by the Core Industrial Properties and represented a 3.2%
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.

by estimating probable exposures to these types of costs for each of the
projects in the Company's development pipeline and applying a series of
probability factors based on the Company's historical experience. The Company
did not record an additional provision for potentially unrecoverable pre-
development costs during the year ended December 31, 1999 since the Company's
probability analyses supported the adequacy of the related allowance
throughout 1999.

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.

$96.1 million for the year ended December 31, 1998 compared to $49.7 million
for the year ended December 31, 1997. Rental income from Office Properties
increased $38.4 million, or 87.8% to $82.2 million for the year ended December
31, 1998 compared to $43.8 million for the year ended December 31, 1997. Of
this increase, $13.3 million was generated by office buildings acquired during
1998 (the "1998 Office Acquisitions") and $0.1 million was generated by the
Office Properties developed by the Company in 1998 (the "1998 Office
Development Properties"). In addition, $21.5 million of the increase was
attributable to a full year of operating results for the office buildings
acquired during 1997, subsequent to the IPO on January 31, 1997 (the "1997
Office Acquisitions"). The remaining $3.5 million of the increase was
generated by the 13 office buildings owned at the IPO and still owned at
December 31, 1998 (the "Existing Office Properties"), and represented a 10.0%
increase in rental income for the Existing Office Properties. This increase
was primarily attributable to leasing activity at the SeaTac Office Center,
including a lease for 211,000 rentable square feet with The Boeing Company
(the "Boeing Lease"), which was effective January 1, 1998. Excluding lease-up
at the SeaTac Office Center, occupancy remained consistent and the Existing
Office Properties experienced an approximate 2.8% increase in rental income
attributable to increases in rental rates.

Tenant reimbursements from Office Properties increased $5.5 million, or
99.6% to $11.0 million for the year ended December 31, 1998 compared to $5.5
million for year ended December 31, 1997. Of this increase, $1.2 million was
attributable to the 1998 Office Acquisitions and the 1998 Office Development
Properties and $2.7 million was attributable to a full year of operating
results from the 1997 Office Acquisitions. The remaining $1.6 million was
attributable to the Existing Office Properties, of which $1.2 million
represented tenant reimbursements under the Boeing Lease. Other income from
Office Properties increased $2.5 million, or 505.7% to $3.0 million for the
year ended December 31, 1998 compared to $0.5 million for the same period in
1997. This increase was primarily due to the recognition of a $1.9 million net
lease termination fee from an office property in San Diego, California. This
property was subsequently re-leased at higher rates for a longer term. In
addition, in 1998 the Company earned a $0.5 million consulting fee for
assisting an existing tenant with potential expansion plans.

Total expenses from Office Properties increased $12.0 million, or 97.6% to
$24.2 million for the year ended December 31, 1998 compared to $12.2 million
for the year ended December 31, 1997. Property expenses increased $7.9
million, or 92.3% to $16.4 million and real estate taxes increased $3.9
million, or 142.3% to $6.6 million for the year ended December 31, 1998
compared to $8.5 million and $2.7 million, respectively, for the year ended
December 31, 1997. Of the collective increase of $11.8 million in property
expenses and real estate taxes, $3.2 million was attributable to the 1998
Office Acquisitions and the 1998 Office Development Properties and $7.0
million was attributable to a full year of operating results from the 1997
Office Acquisitions. The remaining $1.6 million of the increase at the
Existing Office Properties was primarily due to the increase in variable costs
associated with the lease-up of space, and an increase in real estate taxes at
the SeaTac Office Center which resulted from the completion of substantial
renovations. Ground lease expense increased $0.2 million for the year ended
December 31, 1998 compared to the same period in 1997 primarily as a result of
a full year of ground lease expense on two of the 1997 Office Acquisitions.

Net operating income, as defined, from Office Properties increased $34.4
million, or 91.7% to $71.9 million for the year ended December 31, 1998
compared to $37.5 million for the year ended December 31, 1997. Of this
increase, $31.1 million was generated by the 1998 Office Acquisitions, the
1998 Office Development Properties and the 1997 Office Acquisitions. The
remaining increase of $3.3 million was generated by the Existing Office
Properties and represented an 11.2% increase in net operating income for the
Existing Office Properties, which was primarily attributable to lease-up at
the SeaTac Office Center.

buildings acquired during 1998 (the "1998 Industrial Acquisitions") and $2.1
million was generated by the industrial buildings developed by the Company in
1998 (the "1998 Industrial Development Properties"). In addition, $14.0
million of the increase was attributable to a full year of operating results
from the industrial buildings acquired in 1997, subsequent to the IPO on
January 31, 1997 (the "1997 Industrial Acquisitions"). The remaining $0.6
million of the increase was generated by the 11 industrial buildings owned at
the IPO and still owned at December 31, 1998 (the "Existing Industrial
Properties"), and represented a 7.4% increase in rental income for the
Existing Industrial Properties. This increase was primarily attributable to
the lease-up of 46,000 rentable square feet at the La Palma Business Center in
the second quarter of 1998, which had been vacant since the second quarter of
1997. Excluding the lease-up at La Palma Business Center, occupancy and rental
rates for the Existing Industrial Properties remained consistent.

Tenant reimbursements from Industrial Properties increased $2.4 million, or
155.2% to $4.0 million for the year ended December 31, 1998 compared to $1.6
million for year ended December 31, 1997. Of this increase, $0.4 million was
attributable to the 1998 Industrial Acquisitions and the 1998 Industrial
Development Properties, and $1.8 million was attributable to a full year of
operating results from the 1997 Industrial Acquisitions. The remaining $0.2
million was attributable to the Existing Industrial Properties, of which $0.1
million represented an increase in tenant reimbursements at the La Palma
Business Center due to the lease-up of space, and $0.1 million correlated with
an increase in real estate taxes reimbursable by tenants. Other income from
Industrial Properties decreased $0.3 million, or 66.6% to $0.1 million for the
year ended December 31, 1998 compared to $0.4 million for the same period in
1997. Other income for the year ended December 31, 1997 included $0.2 million
related to receivables which were previously written off as uncollectible.

Total expenses from Industrial Properties increased $4.3 million, or 173.4%
to $6.7 million for the year ended December 31, 1998 compared to $2.4 million
for the year ended December 31, 1997. Property expenses increased $2.1
million, or 249.1% to $2.9 million and real estate taxes increased $2.2
million, or 134.7% to $3.8 million for the year ended December 31, 1998
compared to $0.8 million and $1.6 million, respectively, for the year ended
December 31, 1997. Of the collective increase of $4.3 million in property
expenses and real estate taxes, $1.1 million was attributable to the 1998
Industrial Acquisitions and the 1998 Industrial Development Properties and
$3.1 million was attributable to the 1997 Industrial Acquisitions. The
remaining $0.1 million of the increase was attributable to the Existing
Industrial Properties and was due to an increase in real estate taxes
attributable to the reassessment of property values at the date of the IPO.
Property expenses for the Existing Industrial Properties remained consistent
for the year ended December 31, 1998 compared to the same period in 1997.

Net operating income, as defined, from Industrial Properties increased
$18.0 million, or 123.2% to $32.6 million for the year ended December 31, 1998
compared to $14.6 million for the year ended December 31, 1997. Of this
increase, $17.7 million was generated from the 1998 Industrial Acquisitions,
the 1998 Industrial Development Properties and a full year of operating
results from the 1997 Industrial Acquisitions. The remaining increase of $0.3
million was generated by the Existing Industrial Properties and represented a
4.3% increase in net operating income for the Existing Industrial Properties,
which was primarily attributable to lease-up at the La Palma Business Center.

Non-Property Related Income and Expenses

Interest income decreased $1.9 million, or 52.5% to $1.7 million for the
year ended December 31, 1998 compared to $3.6 million for the year ended
December 31, 1997. This decrease was attributable to the interest earned in
the prior year on the $116 million of net proceeds received from the Company's
IPO on January 31, 1997 and the $146 million of net proceeds received from the
Company's follow-on offering in August 1997 (the "August Offering"), which
were invested in short-term investments and which the Company used for the
acquisition of properties and repayment of indebtedness prior to January 1,
1998.

General and administrative expenses increased $2.7 million, or 53.9% to
$7.7 million for the year ended December 31, 1998 compared to $5.0 million for
the year ended December 31, 1997, due to increased management, administrative
and personnel costs associated with the Company's increased portfolio size.

Interest expense increased $9.0 million, or 76.8% to $20.6 million for the
year ended December 31, 1998 compared to $11.6 million for the same period in
1997, primarily due to a general increase in borrowings and higher monthly
average outstanding balances under the Company's unsecured credit facility
during 1998 and $32.9 million of mortgage debt assumed in connection with
fourth quarter 1997 acquisitions. The Company's weighted average interest rate
decreased 0.5% to 7.3% at December 31, 1998 compared to 7.8% at December 31,
1997.

Depreciation and amortization expense increased $12.2 million, or 86.8% to
$26.2 million for the year ended December 31, 1998 compared to $14.0 million
for the same period in 1997. The increase was due to partial

year depreciation on $254 million of 1998 Office and Industrial Acquisitions
and a full year of depreciation on the 1997 Office and Industrial
Acquisitions.

Net income for the year ended December 31, 1998 included a $1.7 million
provision for potentially unrecoverable pre-development costs. The provision
provided for costs incurred for development projects that the Company may at
some point in the development process decide not to pursue. The provision was
established by estimating probable exposures to these types of costs for each
of the projects in the Company's development pipeline and applying a series of
probability factors based on the Company's historical experience.

Income

Net income before gains on dispositions of operating properties, equity in
income of unconsolidated subsidiary, and minority interests increased $25.0
million, or 100.4% to $50.0 million for the year ended December 31, 1998 from
$25.0 million for the year ended December 31, 1997. The increase was primarily
due to the increase in net operating income from the Office and Industrial
Properties of $34.4 million and $18.0 million, respectively, which was
primarily due to the acquisition of 1.4 million and 674,000 rentable square
feet of office and industrial space, respectively, during 1998, and operating
the 2.2 million and 3.7 million rentable square feet of office and industrial
space acquired during 1997 for a full year in 1998. The increase in net
operating income was offset primarily by an increase in interest expense of
$8.9 million and an increase in depreciation and amortization of $12.2
million.

Liquidity and Capital Resources

In November 1999, the Company increased its borrowing capacity and obtained
a new $400 million unsecured revolving credit facility (the "Credit Facility")
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% (7.56% at December 31, 1999), depending
upon the Company's leverage ratio at the time of borrowing, and matures in
November 2002. At December 31, 1999, the Company had borrowings of $228
million outstanding under the Credit Facility and availability of
approximately $86.7 million. Availability under the Credit Facility depends
upon the value of the Company's pool of unencumbered assets. The Company
expects to use the $400 million Credit Facility to finance development
expenditures and for general corporate uses.

In March 1999, the Company borrowed $95.0 million under a mortgage loan
that is secured by nine office and industrial properties, requires monthly
principal and interest payments based on a fixed annual interest rate of
7.20%, amortizes over 25 years and matures in April 2009. The Company used the
proceeds from the mortgage loan to repay borrowings under the $350 million
Credit Facility and to fund development expenditures.

In April 1999, the Company borrowed $30.0 million under a mortgage loan
that is secured by one office property and the related ground leases, requires
monthly principal and interest payments based on a fixed annual interest rate
of 7.15% and matures in May 2017. The Company used the proceeds from the loan
to repay an existing variable rate mortgage loan with an outstanding balance
of $19.0 million, to repay outstanding borrowings under the $350 million
Credit Facility and to fund development expenditures.

In October 1999, the Company borrowed $90.0 million under a secured debt
facility that is secured by 13 office properties, requires monthly interest
payments based on a floating interest rate of LIBOR plus 1.75% and matures in
October 2003. The Company used the proceeds from the secured debt facility to
repay outstanding borrowings under the $350 million Credit Facility and to
fund development expenditures.

As a result of the three new mortgage loans obtained during 1999 and the
repayment of the one previously existing mortgage loan as discussed above, the
Company's outstanding mortgage debt increased to $326 million or 38.8% of the
Company's total market capitalization at December 31, 1999 from $133 million
or 32.0% of the Company's total market capitalization at December 31, 1998.

(1) At December 31, 1999, the Company had an interest rate cap agreement to
cap LIBOR on $150 million of its floating rate debt at 6.5% which expires
in July 2000.

(2) Subsequent to December 31, 1999, the Company entered into an 18-month
interest rate cap agreement to cap LIBOR on $150 million of its floating
rate debt at 6.5% starting in July 2000.

(3) Subsequent to December 31, 1999, the Company entered into a two-year
interest rate swap agreement to fix $150 million of its floating rate
debt. Had this agreement been in place at December 31, 1999, the Company's
percentage of fixed rate debt to total debt would have increased to 69.7%
and the Company's weighted average interest rate for variable and fixed
rate debt would have been 8.0% and 7.8%, respectively.

In December 1999, the Company issued 900,000 9.250% Series D Cumulative
Redeemable Preferred units, representing limited partnership interests in the
Operating Partnership (the "Series D Preferred units"), with a liquidation
value of $50.00 per unit, in exchange for a gross contribution to the
Operating Partnership of $45.0 million. The Company used the contribution
proceeds, less applicable transaction costs and expenses of $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 par 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.

In December 1999, the Company announced the implementation 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,
representing up to approximately 11% of the Company's currently outstanding
shares at December 31, 1999. 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 transacted during December
1999 were funded through proceeds received from the sale of operating
properties during December 1999. The Company intends to finance the
continuation of its share repurchase program in 2000 through proceeds from a
targeted dispositions program of non-strategic and mature industrial assets.
Repurchases during 2000 will be made from time to time in the open market or
through privately negotiated transactions, and may be discontinued at any
time.

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 2.00% 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, 1999, there have been no previously unissued shares acquired
under the Plan.

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 10, 2000, an aggregate of
$313 million of equity securities were available for issuance under the
registration statement.

Capital Expenditures

As of December 31, 1999, the Company had approximately 1.4 million rentable
square feet of office space that was either under construction or committed
for construction at a total budgeted cost of approximately $274 million. The
Company has spent an aggregate of $122 million on these projects as of
December 31, 1999.

The Company intends to finance the presently budgeted $152 million of
remaining development costs with additional construction loan financing,
borrowings under the Credit Facility and working capital.

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. 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.

The agreement with The Allen Group also provides for the development of two
office projects in San Diego, California with approximately 1.1 million
aggregate rentable square feet for an estimated aggregate development cost of
approximately $200 million. During the first quarter of 1999, the Company
purchased a 50% managing interest in both of the development projects. The
Company has the option to purchase The Allen Group's remaining interest in
both projects for a purchase price to be determined upon completion of the
projects. Construction of phase I of both of the office projects was completed
during the third and fourth quarters of 1999. Construction of phases II and
III of the first office project commenced during the second and third quarters
of 1999, respectively, and phase IV is scheduled to begin during the second
quarter of 2000. Construction of phases II and III of the second office
project is scheduled to begin during the first quarters of 2000 and 2001,
respectively. The total presently budgeted investment of $109 million for the
in process and committed phases of these two office projects discussed herein
are included in the Company's total budgeted development costs of $274 million
discussed above. In addition, the Company has spent an aggregate of $42.3
million on the development of these phases as of December 31, 1999, which is
included in the aggregate expenditures of $122 million discussed above.

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 property acquisitions, through
retained cash flow, long-term secured and unsecured borrowings, the issuance
of debt or equity securities or the issuance of common or preferred units of
the Operating Partnership.

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.

Year 2000

The Year 2000 issue ("Y2K") refers to the inability of certain computer
systems, as well as certain hardware and equipment containing date sensitive
data, to recognize accurate dates commencing on or after January 1, 2000. This
has the ability to affect those systems adversely.

In 1997, the Company's Information Technology Committee, comprised of
representatives from senior management and various departments including
accounting, property management and management information systems, identified
three phases in the Company's Y2K efforts: discovery and assessment,
remediation and implementation, and testing and verification. The Company had
successfully completed all of the aforementioned stages by November 1999.

As of March 10, 2000, the Company has not experienced any significant Y2K
problems nor has the Company experienced any interruptions in its normal
operations from Y2K issues experienced by any of its significant tenants,
vendors, suppliers or other relevant third parties. Further, the Company's Y2K
costs incurred to date have been minimal and have not been material to the
Company's financial position or results of operations. The Company does not
expect to incur any significant additional costs for Y2K related issues in the
future.

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.

Historical Cash Flows

The principal sources of funding for development, acquisitions, and capital
expenditures are the Credit Facility, public equity financing, cash flow from
operating activities and secured debt financing. The Company's net cash
provided by operating activities increased $11.2 million, or 15.2% to $84.6
million for the year ended December 31, 1999 compared to $73.4 million for the
year ended December 31, 1998. This increase was primarily attributable to the
increase in net income resulting from the Net Office and Industrial
Acquisitions and the Office and Industrial Development Properties and an
increase in net operating income, as defined, generated by the Core Office and
Industrial Properties. The increase was partially offset by increased interest
expense and general and administrative expenses and a decrease in interest
income.

Cash used in investing activities decreased $151 million, or 43.9% to $193
million for the year ended December 31, 1999 compared to $344 million for the
year ended December 31, 1998. Cash used in investing activities for the year
ended December 31, 1999 consisted primarily of the purchase of three office
buildings for $24.7 million (net of $3.6 million of contributed value in
exchange for which the Company issued common units of the Operating
Partnership and the repayment of an existing $2.3 million note receivable from
related parties), the purchase of the minority interest in one office complex
for $1.2 million, the purchase of 31 acres of undeveloped land for $16.3
million (net of $2.5 million of contributed value in exchange for which the
Company issued common units of the Operating Partnership), the acquisition of
a 50% interest in 55 acres of undeveloped land for $16.1 million (net of $3.8
million of contributed value in exchange for which the Company issued common
limited partnership units of the Operating Partnership), the sale of five
office and five industrial properties for $22.6 million, the sale of 13 acres
of undeveloped land for $5.1 million, expenditures for construction in
progress of $144 million, and $17.0 million in additional tenant improvements
and capital expenditures. Cash used in investing activities for year ended
December 31, 1998 consisted primarily of the purchase of 25 Office and 16
Industrial Properties during 1998 for $236 million (net of $18.1 million of
contributed value in exchange for which the Company issued common units of the
Operating Partnership), the purchase of 56 acres of undeveloped land for $25.4
million (net of $2.5 million of contributed value in exchange for which the
Company issued common units of the Operating Partnership), expenditures for
construction in progress of $65.5 million, and $13.5 million in additional
tenant improvements and capital expenditures.

Cash provided by financing activities decreased $140 million, or 52.3% to
$128 million for the year ended December 31, 1999 compared to $268 million for
the year ended December 31, 1998. Cash provided by financing activities for
the year ended December 31, 1999 consisted primarily of $192 million in net
proceeds from the issuance of mortgage debt and the issuance of $45.0 million
of 9.250% Series D Preferred units (net of $1.2 million aggregate transaction
costs), partially offset by $44.0 million in repayments to the Credit
Facility, $53.6 million in distributions paid to common stockholders and
common unitholders and $5.4 million for the Company's stock repurchase
program. Cash provided by financing activities for the year ended December 31,
1998 consisted primarily of $81.8 million in net proceeds from the issuance of
3,012,326 shares of common stock through four underwritten public offerings
and the issuance of 161,884 shares of common stock through two public direct
placements, the issuance of $75.0 million of 8.075% Series A Preferred units
and $35.0 million of 9.375% Series C Preferred units (net of $3.0 million
aggregate transaction costs), and net proceeds of $132 million from the
issuance of mortgage debt and net borrowings on the Credit Facility, partially
offset by $48.8 million in distributions paid to common stockholders and
common unitholders.

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, 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

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

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133 "Accounting for Derivative Instruments
and Hedging Activities" ("SFAS 133"). SFAS 133 is effective for fiscal years
beginning after June 15, 2000 and requires all derivatives to be recorded on
the balance sheet at fair value as either assets or liabilities depending on
the rights or obligations under the contract. SFAS 133 also establishes new
accounting methodologies for the following three classifications of hedges:
fair value, cash flow and net investment in foreign operations. Depending on
the nature of the hedge, changes in fair value of derivatives will either be
offset against the change in fair value of the hedged assets, liabilities, or
firm commitments or recognized in earnings. The ineffective portion of a
derivative's change in fair value will be immediately recognized in earnings.
Management believes the adoption of SFAS 133 will not have a material impact
on the Company's financial position or results of operations.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Since the Company's IPO in January 1997, management has executed a
financial strategy which has positioned the Company to be flexible and
responsive to the variations in the public and private financial markets. The
principal objectives of the Company's current debt and capital management
strategies are to maintain prudent amounts of leverage and to minimize capital
costs and interest expense while carefully and continuously evaluating
available debt and equity resources.

The primary market risk faced by the Company is the risk of interest rate
fluctuations. More specifically, the primary market risk faced by the Company
is market risk resulting from increasing LIBOR based interest rates since at
December 31, 1999, interest expense on $318 million, or 57.5%, of the
Company's total $554 million of debt, including borrowings under the Credit
Facility, are tied to a LIBOR based interest rate. As a result, the Company
pays lower rates of interest in periods of decreasing interest rates and
higher rates of interest in periods of increasing interest rates. To mitigate
the effect of changes in interest rates on Credit Facility borrowings and in
compliance with Credit Facility debt covenants, in July 1999, the Company
entered into two interest rate cap agreements with a total notional amount of
$150 million to effectively limit interest expense for borrowings under the
Credit Facility during periods of increasing interest rates. The agreements
have LIBOR based cap rates of 6.50% and expire in July 2000. The Company's
exposure is limited to the unamortized cost of the caps. The cost of the cap
agreements were fully amortized at December 31, 1999.

The Company is also subject to risk resulting from fluctuations in the
general level of U.S. interest rates since at December 31, 1999, $236 million,
or 42.5%, of the Company's total $554 million of debt arrangements are
established at a fixed weighted average interest rate of 7.75%, and since
quarterly distributions of $1.5 million, $0.8 million, and $1.0 million paid
to Series A, Series C and Series D Preferred unitholders, respectively, are
calculated based upon a fixed rate of 8.075%, 9.375%, and 9.250% respectively.
As a result, the Company will pay contractually agreed upon fixed rates of
interest regardless of fluctuations in the general interest rate environment.

The tabular presentation below provides information about the Company's
interest rate sensitive financial and derivative instruments at December 31,
1999. All of the Company's interest rate sensitive financial and derivative
instruments are designated as held for purposes other than trading. Following
the tabular presentation is additional information summarizing changes in the
Company's market risk profile from 1998 to 1999 as well as changes in the
Company's market risk profile subsequent to December 31, 1999.

For the Credit Facility, the table presents the assumption that the
outstanding principal balance at December 31, 1999 will be paid upon the
Credit Facility's maturity in November 2002. The table also presents the
related expected maximum interest rate index for outstanding Credit Facility
borrowings from 2000 through 2002.

For variable rate mortgage debt, the table presents the assumption that the
outstanding principal balance at December 31, 1999 will be paid upon maturity
in October 2003. The table also presents the related interest rate index for
outstanding variable rate mortgage debt borrowings from 2000 through 2003.

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

For the Series A and Series C Cumulative Redeemable Preferred units (the
"Preferred units"), the table reflects the assumption that the Company is not
contractually obligated to repay the outstanding balance of the Preferred
units since the 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 Preferred units
become exchangeable at the option of the majority of the holders. For the
Series D Cumulative Redeemable Preferred units (the "Preferred units"), the
table reflects the assumption that the

Company is not contractually obligated to repay the outstanding balance of the
Preferred units since the 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 Preferred units become exchangeable at the option of
the majority of the holders. The table also presents the related weighted-
average interest rate for outstanding Preferred units from 2000 through the
exchange date. The same interest rates will apply when the Preferred units are
exchanged into the Cumulative Redeemable Preferred stock.

For interest rate caps, the table presents notional amounts, average cap
rates and the related interest rate index upon which cap rates are 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, 1999.

Changes in Primary Risk Exposures

Changes from December 31, 1998 to December 31, 1999

The following table demonstrates the change in market risk profile of the
Company's outstanding debt from December 31, 1998 to December 31, 1999. The
change from year to year reflects a conscious strategy by management to fix a
larger proportion of the Company's outstanding debt balances during 1999.

(1) At December 31, 1999, the Company had an interest rate cap agreement to
cap LIBOR on $150 million of its floating rate debt at 6.5% which expires
in July 2000.
(2) Subsequent to December 31, 1999, the Company entered into an 18-month
interest rate cap agreement to cap LIBOR on $150 million of its floating
rate debt at 6.5% starting in July 2000.
(3) Subsequent to December 31, 1999, the Company entered into a two-year
interest rate swap agreement to fix $150 million of its floating rate
debt. Had this agreement been in place at December 31, 1999, the Company's
percentage of fixed rate debt to total debt would have increased to 69.7%
and the Company's weighted average interest rate for variable and fixed
rate debt would have been 8.0% and 7.8%, respectively.

During 1999, the Company issued 900,000 Series D Preferred units in
addition to the 1,200,000 Series A and 700,000 Series C Preferred units issued
during the year ended December 31, 1998. Beginning in the first quarter of
2000, quarterly distributions of $1.0 million, calculated using a fixed rate
of 9.25%, will be payable to the Series D Preferred unitholders in addition to
the $1.5 million and $0.8 million currently paid to the Series A and Series C
unitholders, respectively. For the year ended December 31, 1999, distributions
accrued for the Series D Preferred unitholders totaled approximately $0.2
million.

Changes Subsequent to December 31, 1999

In February 2000, the Company entered into an interest rate swap agreement
with a total notional amount of $150 million and an interest rate cap
agreement with a total notional amount of $150 million to effectively limit
interest expense on the Company's floating rate debt instruments during
periods of increasing interest rates. The swap agreement, which begins in
February 2000 and expires in February 2002, requires the Company to pay a
fixed rate interest payment based on an interest rate of 6.95% and receive a
floating rate interest payment based on one-month LIBOR. The cap agreement,
which begins in July 2000 when the Company's existing $150 million cap
agreements expire, has a LIBOR based cap rate of 6.50% and expires in January
2002. The Company's exposure on the cap agreement is limited to the $1.9
million cost of the cap agreement which the Company will amortize over the
life of the agreement. Had these two agreements been in place as of December
31, 1999, the Company's ratio of fixed rate debt to total debt would have
increased from 42.5% to 69.7% and the Company's weighted average interest rate
for fixed and variable rate debt would have increased from 7.75% and 7.67%,
respectively, to 7.97% and 7.76%, respectively.

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, 1999 and 1998, the
related consolidated statements of operations and shareholders' equity for the
years ended December 31, 1999 and 1998 and the period February 1, 1997 to
December 31, 1997, and the combined statements of operations and accumulated
deficit of the Kilroy Group (described in Note 1) for the period January 1,
1997 to January 31, 1997; and the consolidated statements of cash flows for
the years ended December 31, 1999 and 1998 and the combined statement of cash
flows for the year ended December 31, 1997. 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 financial statements present fairly, in all material
respects, the financial position of the Company as of December 31, 1999 and
1998, and the results of operations and cash flows of the Company and the
Kilroy Group for the respective stated periods 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 and combined financial statements taken as a whole,
presents fairly in all material respects, the information set forth therein.

NOTES TO CONSOLIDATED AND COMBINED FINANCIAL STATEMENTS

Three Years Ended December 31, 1999

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.

As of December 31, 1999, the Company's stabilized portfolio of operating
properties consisted of 84 office buildings (the "Office Properties") and 87
industrial buildings (the "Industrial Properties," and together with the
Office Properties, the "Properties") which encompassed approximately 6.1
million and 6.5 million rentable square feet, respectively, and was 96.7%
occupied. The Company's stabilized portfolio consists of all of the Company's
Office and Industrial Properties, excluding properties recently developed by
the Company that have not yet reached 95.0% occupancy ("lease-up" properties)
and projects currently under construction or in pre-development. As of
December 31, 1999, the Company had seven office properties under construction
which when completed are expected to encompass an aggregate of approximately
861,500 rentable square feet. The Company did not have any properties in
lease-up at December 31, 1999 since all of the properties developed and
completed by the Company during 1999 and 1998, encompassing an aggregate of
approximately 862,400 and 1.1 million of rentable square feet, respectively,
stabilized during 1999. All but 15 of the Company's properties are located in
Southern California. All of the Company's development projects are located in
Southern California.

The Company owns its interests in all of its 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, 1999 and 1998, it owned an 86.8% general partnership
interest. The remaining 13.2% 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 (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 partner interest. The Operating Partnership, owns the remaining 99%
limited partner interest.

In 1998, the Company formed two limited liability companies, Kilroy Gateway
Partners, L.L.C. and Kilroy Carmel Partners, L.L.C. (collectively, the
"Development LLCs") to develop two multi-phased office projects in San Diego,
California. During the first quarter of 1999, the Company, through the
Operating Partnership, became a 50% managing partner in 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 Allen Group, a group of affiliated real estate development and
investment companies based in Visalia, California, is the other 50% owner.
Unless otherwise indicated, all references to the Company include the
Operating Partnership, the Finance Partnership, Finance Inc. and the
Development LLCs.

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. KI had historically been engaged in the
acquisition, management, financing, construction and leasing of office and
industrial properties and providing development services to third party owners
for a fee. The accompanying combined financial statements of the Kilroy Group
have been presented on a combined basis because of common ownership and
management and because the entities were the subject of a business combination
with the Company in 1997.

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 Finance Inc. The
consolidated financial statements as of and for the years ended December 31,
1999 and 1998 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.

The combined financial statements of the Kilroy Group reflect a combination
of real estate properties which were under the common control of KI and/or its
stockholders, including John B. Kilroy, Sr. and John B. Kilroy, Jr., and which
were contributed to the Operating Partnership upon the consummation of the
IPO. The Kilroy Group is considered the predecessor entity to the Company due
to common ownership and management; therefore, its combined financial
statements are presented for comparative purposes. All significant
intercompany balances and transactions have been eliminated in the combined
financial statements.

Significant Accounting Policies:

Operating properties--Operating properties are stated 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 properties
recently developed by the Company that have not yet reached 95.0% occupancy
("lease-up" properties) and projects currently under construction or in pre-
development. Lease-up properties are included in land and improvements and
building and improvements on the consolidated balance sheets upon building
shell completion.

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, 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 years ended December 31, 1999 and 1998,
the eleven months ended December 31, 1997, and the one month ended January 31,
1997 was $29.0 million, $23.7 million, $11.5 million and $0.7 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 capitalized during the period in which activities necessary to get
the property ready for its intended use are in

F-9

KILROY REALTY CORPORATION CONSOLIDATED
AND KILROY GROUP COMBINED

NOTES TO CONSOLIDATED AND COMBINED FINANCIAL STATEMENTS--(Continued)

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.

At December 31, 1999 and 1998, construction in progress was carried net of
a $0.7 million and $1.7 million allowance for potentially unrecoverable pre-
development costs, respectively. The allowance, which provides for costs
incurred for development projects that the Company may at some point in the
development process decide not to pursue, was established by estimating
probable exposures to these types of costs for each of the projects in the
Company's development pipeline. Management's determination of the allowance
was calculated on a project by project basis using a series of probability
factors based on the Company's historical experience. The allowance is
increased by provisions charged against income. The allowance for potentially
unrecoverable pre-development costs at December 31, 1999 and 1998 was
maintained at a level believed to be adequate by management.

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 and cash reserves
for property taxes, capital expenditures and tenant improvements.

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. The allowance for uncollectible tenant
receivables and unbilled deferred rent was maintained at a level believed
adequate by management to absorb potential losses from both current and
deferred tenant receivables at December 31, 1999 and 1998.

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 20 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 (see Note 8).

Other income--Other income includes revenue earned from lease termination
fees, management fees, and for the year ended December 31, 1999, gains on
dispositions of undeveloped land.

Extraordinary gains--On January 31, 1997, pursuant to a forbearance
agreement with an insurance company, the Kilroy Group exercised the right to
purchase a mortgage note payable with a principal balance of

F-10

KILROY REALTY CORPORATION CONSOLIDATED
AND KILROY GROUP COMBINED

NOTES TO CONSOLIDATED AND COMBINED FINANCIAL STATEMENTS--(Continued)

$20.2 million and $2.4 million of accrued interest for $16.1 million. The
forgiveness resulted in an extraordinary gain of $3.2 million including the
write-off of $1.3 million of deferred financing fees.

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 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.
The Company had met all of its REIT distribution and technical requirements at
December 31, 1999, 1998 and 1997. 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, 1999 and 1998.

Derivative financial instruments--The Company's derivative financial
instruments at December 31, 1999 and 1998 consisted of two interest rate cap
agreements with an aggregate notional amount of $150 million. The Company
purchased the interest rate cap agreements to effectively limit interest
expense exposure on borrowings under the Company's floating rate debt
instruments during periods of increasing interest rates.

The Company's interest rate cap agreements consist of agreements with other
counterparties to receive, at specified intervals and over specified periods
of time, payments equal to the excess, if any, between the hypothetical
interest rate (cap rate) and the then current market rate of interest as
calculated by reference to a specified notional amount and a specified
interest rate index. The only amount the Company is obligated to pay is an
initial premium, which is included in other assets on the consolidated balance
sheets and amortized to interest expense ratably over the shorter of the term
of the cap agreement or the remaining life of the debt instrument the cap
agreement is hedging. At the time the agreements were entered into, the cap
rates exceeded market. The interest rate specified by the agreements have been
and are expected to continue to be highly correlated with the interest rates
on the Company's floating rate debt. Interest payments to be received as a
result of interest rate cap agreements are accrued in other assets and
recognized as a reduction of interest expense related to the designated debt
(the accrual accounting method). There were no payments from the interest rate
cap agreements accrued at December 31, 1999 and 1998.

Subsequent to December 31, 1999, the Company entered into an interest rate
swap agreement with a notional amount of $150 million and an interest rate cap
agreement with a notional amount of $150 million. Under the Company's swap
agreement the Company will be obligated to pay a fixed interest rate and
receive a floating interest rate as calculated by reference to a specified
interest rate index. The floating interest rate specified by the agreement has
been and is expected to continue to be highly correlated with the floating
interest rates on the Company's floating rate debt. Interest payments to be
paid or received as a result of interest rate swap agreements will be accrued
in accrued expenses on the consolidated balance sheets and recognized as an
adjustment of interest expense related to the designated debt (the accrual
accounting method).

KILROY REALTY CORPORATION CONSOLIDATED
AND KILROY GROUP COMBINED

NOTES TO CONSOLIDATED AND COMBINED FINANCIAL STATEMENTS--(Continued)

Use of estimates--The preparation of financial statements in conformity
with generally accepted accounting principles 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--156 of the Company's total 171 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.

One office property tenant, Hughes Space and Communications, accounted for
approximately 6.4%, 7.4%, and 14.7% of the Company's total base rental
revenues for the years ended December 31, 1999 and 1998, and the eleven months
ended December 31, 1997, respectively. At December 31, 1999 and 1998, 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, 1999 and 1998, the Company had cash accounts in
excess of FDIC insured limits.

Recent accounting pronouncements--In June 1998, the Financial Accounting
Standards Board issued Statement of Financial Accounting Standards No. 133
"Accounting for Derivative Instruments and Hedging Activities" ("SFAS 133").
SFAS 133 is effective for fiscal years beginning after June 15, 2000 and
requires all derivatives to be recorded on the balance sheet at fair value as
either assets or liabilities depending on the rights or obligations under the
contract. SFAS 133 also establishes new accounting methodologies for the
following three classifications of hedges: fair value, cash flow and net
investment in foreign operations. Depending on the nature of the hedge,
changes in fair value of derivatives will either be offset against the change
in fair value of the hedged assets, liabilities, or firm commitments or
recognized in earnings. The ineffective portion of a derivative's change in
fair value will be immediately recognized in earnings. Management believes the
adoption of SFAS 133 will not have a material impact on the Company's
financial position or results of operations.

3. Acquisitions, Dispositions, and Completed Development Projects

Acquisitions

During the year ended December 31, 1999, the Company consummated a series
of transactions to acquire three office buildings (see Note 21) 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 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 New York Stock Exchange ("NYSE") at the time
of acquisition. The three office buildings contain approximately 176,900
aggregate rentable square feet. The common units were issued in connection
with the acquisition of two office buildings located in San Diego, California
from entities controlled by Richard S. Allen, a former member of the Company's
Board of Directors (see Note 13).

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

F-12

KILROY REALTY CORPORATION CONSOLIDATED
AND KILROY GROUP COMBINED

NOTES TO CONSOLIDATED AND COMBINED FINANCIAL STATEMENTS--(Continued)

common 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 of acquisition. The common units were issued in
connection with the acquisition of three acres of undeveloped land located in
San Diego, California from The Allen Group, a group of affiliated real estate
development and investment companies based in Visalia, California (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
office projects with approximately 1.1 million aggregate rentable square feet
over the next five years (see Note 13).

During the year ended December 31, 1998, the Company consummated a series
of transactions to acquire 25 office and 16 industrial buildings (the "1998
Acquisitions") (see Notes 20 and 21) for an aggregate purchase price of
approximately $236 million in cash and 703,869 common units of the Operating
Partnership valued at approximately $18.1 million based upon the closing share
price of the Company's common stock as reported on the NYSE at the time of
acquisition. The office and industrial buildings contain approximately 1.4
million and 674,000 aggregate rentable square feet, respectively. The common
units were issued in connection with the acquisition of four office buildings
located in San Diego, California and one industrial building located in Reno,
Nevada from entities controlled by Richard S. Allen (see Note 13).

During the year ended December 31, 1998, the Company consummated a series
of transactions to acquire approximately 56 acres of undeveloped land for an
aggregate purchase price of approximately $25.4 million in cash and 90,787
common 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 of acquisition. The common units were issued in
connection with the acquisition of 18 acres of undeveloped land located in
Calabasas, California from a partnership controlled 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 (see Note 13).

The 1999 and 1998 operating property and undeveloped land acquisitions were
all funded primarily with existing working capital and borrowings on the
Company's revolving unsecured credit facility.

Dispositions

During the year ended December 31, 1999, the Company consummated a series
of transactions to sell five office and five industrial buildings for an
aggregate sales price of $14.6 million and $8.0 million, respectively. The
office and industrial buildings contained approximately 113,700 and 335,800
aggregate rentable square feet, respectively. The net gain on sale of $46,000
from these dispositions is reported after income from operations in the
consolidated statements of operations. The Company used the sales proceeds to
repay borrowings under its revolving unsecured credit facility, to fund
development expenditures and to fund the Company's share repurchase program
(see Note 9).

During the year ended December 31, 1999, the Company consummated a series
of transactions to sell 13 acres of undeveloped land for an aggregate sales
price of $5.1 million. Of the total 13 acres sold, eight acres related to the
sale of a portion of the 18-acre undeveloped land parcel in Calabassas,
California which the Company acquired from John B. Kilroy, Sr. and John B.
Kilroy, Jr. during 1998 (see Note 13). As a result of the sale, a portion of
the public facility bonds related to this undeveloped land parcel was defeased
(see Note 13).

F-13

KILROY REALTY CORPORATION CONSOLIDATED
AND KILROY GROUP COMBINED

NOTES TO CONSOLIDATED AND COMBINED FINANCIAL STATEMENTS--(Continued)

The total gain on sale of $0.5 million from these dispositions is included in
other income in the consolidated statements of operations. The Company used
the sales proceeds to repay borrowings under its revolving credit facility and
to fund development expenditures.

Completed Development Projects

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 of office
and industrial space, respectively. All 10 of these buildings were stabilized
by the Company during 1999 and were therefore included in the Company's
stabilized portfolio of operating properties at December 31, 1999.

During the year ended December 31, 1998, the Company completed the
development of one office and five industrial buildings encompassing an
aggregate of approximately 78,000 and 1.0 million rentable square feet,
respectively. Of the total 1.1 million rentable square feet completed during
1998, 344,500 rentable square feet was stabilized by the Company during 1998
and was included in the Company's stabilized operating portfolio at December

The Company's mortgage debt was secured by 55 properties at December 31,
1999 with a combined net book value of $459 million and 24 properties at
December 31, 1998 with a combined net book value of $166 million. As of
December 31, 1999 and 1998, the Company's mortgage debt had a weighted average
interest rate of 7.80% and 8.22%, respectively.

At December 31, 1999, six of the Company's mortgage loans contained
restrictions that would require the payment of prepayment penalties for the
acceleration of outstanding debt. The mortgage notes payable are secured by
deeds of trust on certain of the Company's properties and the assignment of
certain rents and leases associated with those properties.

Scheduled principal payments for the above mortgage loans at December 31,

7. Unsecured Line of Credit

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
(the "$350 million Credit Facility") which was scheduled to mature in February
2000, with the option to extend for one year. The Credit Facility bears
interest at a rate between LIBOR plus 1.13% and LIBOR plus 1.75% (7.56% at
December 31, 1999), depending upon the Company's leverage ratio at the time of
borrowing, and matures in November 2002. At December 31, 1999, the Company had
borrowings of $228 million outstanding under the Credit Facility and
availability of approximately $86.7 million. Availability under the Credit
Facility depends upon the value of the Company's pool of unencumbered assets.
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 Credit Facility to finance
development expenditures and for general corporate uses.

In July 1998, the Company entered into two interest rate cap agreements
with a total notional amount of $150 million to effectively limit interest
expense on the Company's floating rate debt instruments during periods of
increasing interest rates. The agreements have LIBOR based cap rates of 6.50%
and expire in July 2000. The Company's exposure is limited to the $0.2 million
cost of the cap agreements, which the Company has amortized and included as a
component of interest expense in the consolidated statement of operations. The
cost of the cap agreements were fully amortized at December 31, 1999. The $0.1
million unamortized balance of the cost of the cap agreements at December 31,
1998 was included in other assets in the consolidated balance sheet.

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 begins in February 2000 and 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.

In February 2000, the Company entered into an interest rate cap 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 begins in July 2000 when the Company's
existing $150 of cap agreements expire, has a LIBOR based cap rate of 6.50%
and expires in January 2002. The Company's exposure is limited to the $1.9
million cost of the cap agreement which the Company will amortize over the
life of the agreement and include as a component of interest expense in the
consolidated statements of operations.

As of December 31, 1998, the Company maintained a $350 million unsecured
Credit Facility with a bank group led by Morgan Guaranty Trust Company of New
York. The $350 million Credit Facility bore interest at a rates that ranged
from LIBOR plus 1.00% to LIBOR 1.38% (6.81% at December 31, 1998), depending
on the Company's leverage ratio at the time of borrowing, and was scheduled to
mature in February 2000, with the option to extend for one year. The fee for
unused funds was 0.20% based on outstanding balances. At December 31, 1998,
there were borrowings of $272 million and one letter of credit in the amount
of $1.0 million outstanding under the $350 million Credit Facility. The $1.0
million letter of credit was issued in connection with a signed commitment
letter for a mortgage loan that the Company executed during 1999. The $350
million Credit Facility was used to finance property acquisitions, development
and for general corporate uses.

The Credit Facility contains 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 covenants at December 31, 1999.

8. Minority Interests

During the year ended December 31, 1999 and 1998, the Operating Partnership
issued 472,034 and 794,656 common limited partnership units in the Operating
Partnership, respectively, in connection with certain operating property and
undeveloped land acquisitions (see Notes 3 and 13). In addition, 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 during the third and

for-one basis (see Notes 9 and 13). The Company owned an 86.8% general
partnership interest in the Operating Partnership as of December 31, 1999 and
1998.

In March 1999, the Company became a 50% managing member in each of the
Development LLCs 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.

In December 1999, the Company issued 900,000 9.250% Series D Cumulative
Redeemable Preferred units, representing limited partnership interests in the
Operating Partnership (the "Series D Preferred units"), with a liquidation
value of $50.00 per unit, in exchange for a gross contribution to the
Operating Partnership of $45.0 million. The Company used the contribution
proceeds, less applicable transaction costs and expenses of $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 par 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 C Cumulative Redeemable
Preferred stock beginning December 9, 2009, or earlier under certain
circumstances.

Operating Partnership of $35.0 million. The Company used the contribution
proceeds, less applicable transaction costs and expenses of $0.9 million, for
the repayment of borrowings outstanding under the Credit Facility. The Series
C Preferred units, which may be called by the Operating Partnership at par on
or after November 24, 2003, have no stated maturity or mandatory redemption
and are not convertible into any other securities of the Operating
Partnership. The Series C Preferred Units are exchangeable at the option of
the majority of the holders for shares of the Company's 9.375% Series C
Cumulative Redeemable Preferred stock beginning November 24, 2008, or earlier
under certain circumstances.

In February 1998, the Company issued 1,200,000 8.075% Series A Cumulative
Redeemable Preferred units, representing limited partnership interests in the
Operating Partnership (the "Series A Preferred units"), with a liquidation
value of $50.00 per unit, in exchange for a gross contribution to the
Operating Partnership of $60.0 million. The Company used the contribution
proceeds, less applicable transaction costs and expenses of $1.7 million, for
the repayment of borrowings outstanding under the Credit Facility. In April
1998, the Company

F-17

AND KILROY GROUP COMBINED

NOTES TO CONSOLIDATED AND COMBINED FINANCIAL STATEMENTS--(Continued)

issued an additional 300,000 Series A Preferred units for a gross contribution
to the Operating Partnership of $15.0 million. The Company used the
contribution proceeds, less applicable transaction costs and expenses of $0.4
million for the repayment of borrowings outstanding under the Credit Facility.
The Series A Preferred units, which may be called by the Operating Partnership
at par on or after February 6, 2003, have no stated maturity or mandatory
redemption and are not convertible into any other securities of the Operating
Partnership. The Series A Preferred units are exchangeable at the option of
the majority of the holders for shares of the Company's 8.075% Series A
Cumulative Redeemable Preferred stock beginning February 6, 2008, or earlier
under certain circumstances.

The Company makes quarterly distributions to the Series A, Series C and
Series D Preferred unitholders on the 15th day of each February, May, August
and November. Included in the Series A, Series C and Series D Preferred unit
balances on the balance sheet at December 31, 1999 were $0.8 million, $0.4
million and $0.2 million of accrued distributions payable to the Series A,
Series C and Series D Preferred unitholders, respectively. Included in the
Series A and Series C Preferred unit balances on the balance sheet at December
31, 1998 were $0.8 million and $0.3 million of accrued distributions payable
to the Series A and Series C Preferred unitholders, respectively.

9. Stockholders' Equity

In December 1999, the Company announced the implementation 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,
representing up to approximately 11% of the Company's currently outstanding
shares at December 31, 1999. 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 transacted during December
1999 were funded through proceeds received from the sale of operating
properties disposed of by the Company during December 1999 (see Note 3). The
Company intends to finance the continuation of its share repurchase program
during 2000 through proceeds from a targeted dispositions program of non-
strategic and mature industrial assets. Repurchases during 2000 will be made
from time to time in the open market or through privately negotiated
transactions, and may be discontinued at any time.

of outstanding indebtedness and general corporate uses. As of December 31,
1999, there have been no previously unissued shares acquired under the Plan.

During 1999, the Company filed two registration statements on Form S-3 with
the SEC which registered the potential issuance and resale of up to a total of
3,867,850 shares of the Company's common stock in exchange for 3,867,850
common limited partnership units of the Operating Partnership previously
issued in connection with certain 1997 and 1998 property acquisitions. The SEC
declared the registration statements effective in September and October 1999.
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 of the proceeds from
the issuance of the common stock to the identified common unitholders. 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 during
the third and fourth quarters of 1999 into shares of the Company's common
stock (see Notes 8 and 13).

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.

In October 1998, the Company adopted a Preferred Stock Purchase Rights Plan
(the "Rights Plan") under which common stockholders of record on October 15,
1998 received one Right for each share of the Company's outstanding common
stock. Each Right, which entitles its holder to buy one one-hundredth of a
share of voting preferred stock at an exercise price of $71.00, becomes
exercisable, subject to limited exceptions, if a person or group acquires 15%
or more of the Company's common stock or announces a tender offer for 15% or
more of the Company's common stock. Upon such event, each Right entitles its
holder to purchase, at the Right's then exercise price, a number of shares of
the Company's common stock equal to the market value at that time of twice the
Right's exercise price. Rights held by the acquirer will become void and will
not be exercisable upon the announcement of the acquisition. In the event that
the Company is acquired in a merger or other business combination, each Right
entitles its holder to purchase, at the Right's then current exercise price, a
number of shares of the acquiring company's common stock equal to the market
value at that time of twice the Right's exercise price. The Rights Plan
expires October 2, 2008. The Board may elect to redeem the Rights at $.001 per
Right.

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. Through December 31, 1999, the Company completed
four underwritten offerings aggregating 3,012,326 shares of common stock and
two direct placements aggregating 161,884 shares of common stock with
aggregate net proceeds of $81.8 million. As of March 10, 2000, an aggregate of
$313 million of equity securities were available for issuance under the
registration statement. The Company, as general partner of the Operating
Partnership and as required by the terms and conditions of the Operating
Partnership's partnership agreement, contributed the net proceeds of the
offerings to the Operating Partnership, which used the net proceeds to repay
borrowings under the Credit Facility.

The Company has operating leases with tenants that expire at various dates
through 2014 and are either subject to scheduled fixed increases or
adjustments based on the Consumer Price Index. Generally, the leases grant
tenants renewal options. Leases also provide for additional rents based on
certain operating expenses. Future minimum rent under operating leases,

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, 1999 and 1998, the Company contributed $0.1 million 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

F-20

KILROY REALTY CORPORATION CONSOLIDATED

granted. The Stock Plan authorizes the issuance of 3,000,000 shares of common
stock of the Company. As of December 31, 1999 and 1998, 100,000 shares have
been issued as restricted shares of common stock and options to purchase
25,000 and 1,339,000 shares of common stock, respectively, were granted to
Directors, officers and employees under the Stock Plan. At December 31, 1999
and 1998, 1,003,000 and 355,000 of the options, respectively were exercisable
and had a weighted average exercise price of $23.24 and $23.59, respectively.
The weighted average exercise price of the options outstanding at December 31,
1999 and 1998 was $23.07 and $23.37, respectively, with a weighted average
remaining contractual life of 8.0 and 9.1 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. The shares of
restricted stock which have been granted, were sold at a purchase price equal
to $0.01 and vest 20% per year over a five-year period. Restricted stock has
the same dividend and voting rights as common stock and is considered to be
currently issued and outstanding. 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. In connection
with the IPO in January 1997, 100,000 shares of restricted stock were issued
to an executive officer of the Company for a price of $1,000. Compensation
expense relating to these shares was approximately $0.5 million for the years
ended December 31, 1999 and 1998 and $0.4 million for the eleven months ended
December 31, 1997.

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

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." 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:

The fair value of each option grant issued in 1999, 1998, and 1997 is
estimated on the date of grant using the Black-Scholes option-pricing model
with the following weighted average assumptions (amounts shown as 1999, 1998
and 1997, respectively): (a) dividend yield of 6.73%, 6.31% and 6.00%, (b)
expected volatility of the Company's stock of 27.0%, 26.2% and 21.8%, (c) risk
free interest rate of 6.64%, 4.73% and 5.44%, (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

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. 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.

The agreement with The Allen Group also provides for the development of two
office projects in San Diego, California with approximately 1.1 million
aggregate rentable square feet for an estimated aggregate development cost of
approximately $200 million. During the first quarter of 1999, the Company
purchased a 50% managing interest in both of the development projects (see
Notes 3 and 13). The Company has the option to purchase The Allen Group's
remaining interest in both projects for a purchase price to be determined upon
completion of the projects. Construction of phase I of both of the office
projects was completed during the third and fourth quarters of 1999.
Construction of phases II and III of the first office project commenced during
the second and third quarters of 1999, respectively, and phase IV is scheduled
to begin during the second quarter of 2000. Construction of phases II and III
of the second office project is scheduled to begin during the first quarters
of 2000 and 2001, respectively. The total presently budgeted investment for
the in process and committed phases of these two office projects discussed
herein is approximately $109 million, of which the Company has spent an
aggregate of $42.3 million as of December 31, 1999.

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 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

In March 1999, the Company acquired three office buildings in San Diego,
California from entities controlled by Richard S. Allen 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. 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 Richard S. Allen 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 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 Richard S. Allen 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
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.

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 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
five 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 Richard S. Allen 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 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.

During the third and fourth quarters of 1999, 440,000 common limited
partnership units owned by John B. Kilroy, Sr., John B. Kilroy, Jr., and
Kilroy Industries were exchanged into shares of the Company's common stock on
a one-for-one basis (see Notes 8 and 9).

During 1998, the Company issued 703,869 common units of the Operating
Partnership valued at $18.1 million based upon the closing share price of the
Company's common stock as reported on the NYSE at the time of the respective
acquisitions. The common units were issued in connection with the acquisition
of four office buildings located in San Diego, California and one industrial
building located in Reno, Nevada from entities controlled by Richard S. Allen.
A former Executive Vice President of the Company received 303,316 of the total
703,869 common units issued in connection with the acquisitions. The
acquisitions were based upon terms that the Company believes were comparable
to terms obtainable from third-parties based on arm's-length negotiations.

In April 1998, the Company acquired 18 acres of undeveloped land in
Calabasas, California from a partnership controlled by John B. Kilroy, Sr. and
John B. Kilroy, Jr. in exchange for $0.4 million in cash and the issuance of
90,787 common limited partnership units of the Operating Partnership valued at
$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. The
land is part of a 66-acre development site in Calabasas, California which is
presently entitled for over 1.0 million rentable square feet of office, retail
and hotel development. The acquisition was based upon terms which the Company
believes were comparable to arm's-length negotiations. In February 1999, the
Company sold eight acres of this 18-acres undeveloped land parcel to the City
of Calabasas for a total sales price of $1.4 million. The Company presently
plans to develop 213,000 rentable square feet of office space on the remaining
ten acres it currently owns. The infrastructure improvements on the land were
financed with public facility bonds which were refinanced in February 1999. In
connection with the refinancing, the portion of the original obligation that
related to the eight acres the Company sold to the City of Calabasas was
defeased. The refinanced bonds, which were sponsored by the City of Calabasas,
currently have a principal balance of $12.5 million and consist of: $5.9
million in serial bonds that mature annually beginning on September 1, 2000
through September 1, 2012 with annual principal payments ranging from $0.4
million to $0.6 million and interest rates ranging from 4.00% to 5.55%; $3.4
million of 5.65% Term Bonds due September 1, 2020; and $3.2 million of 5.75%
Term Bonds due September 1, 2028. Principal and interest on the public
facility bonds are to be charged to the Company and the other property owners
through special property tax bills through 2028. The bonds do not contain
cross-collateralization provisions and therefore if one property owner
defaulted on their special tax payments, the other property owners would not
be obligated to repay the defaulted taxes. Based on the planned development of
the total site, the Company's maximum obligation for its portion of the
development site is currently estimated at $5.5 million, but may decrease
depending on the actual size and number of buildings built. Because the
assessment on each individual property owner is dependent upon the rate of
development of the entire development site and therefore is not fixed and
determinable, the obligation was not recorded by the Company. The periodic
assessments are currently capitalized as development costs and will be charged
to operations upon the completion of construction.

Pursuant to management agreements, the Operating Partnership provided
management and leasing services during 1999, 1998 and 1997, and KSI provided
development services during 1998 and 1997, 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, $0.2 million and
$0.1 million for the years ended December 31, 1999 and 1998 and the eleven
months ended December 31, 1997, respectively, relating to the management and
leasing services. KSI recorded fees of $0.1 million and $0.2 million for the
year ended December 31, 1998 and the eleven months ended December 31, 1997,
respectively, 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 Richard S. Allen. At December 31, 1999 and 1998, KSI had a receivable
balance of $0.3 million and $0.2 million for management fees earned,
respectively.

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 mortgage debt,
outstanding borrowings on the Credit Facility and $350 million Credit
Facility, and notes receivable from related parties approximate fair value
since the interest rates on these instruments are equivalent to rates
currently offered to the Company.

For fixed rate mortgage 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 mortgage
debt was $225 million and $121 million at December 31, 1999 and 1998,
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 $146 million at
December 31, 1999. The fair value of the Series A and Series C Preferred units
was $99.2 million at December 31, 1998.

For interest rate cap agreements, the carrying amount, which is comprised
of the unamortized premium the Company paid to enter into the agreements,
approximates fair value since at December 31, 1999 and 1998, the cap rates
exceeded the market rate of the contractually specified interest rate indices.

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 units of the Operating Partnership to be dilutive securities since the
exchange of common 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 years ended December 31, 1999 and 1998 and
the eleven months ended December 31, 1997:
