KILROY REALTY CORPORATION

Common Stock

- -------------------------------------------------------------------------------
Kilroy Realty Corporation and its subsidiaries (the "Company") are engaged in
the business of owning, acquiring, developing, managing and leasing principally
Class A suburban office and industrial buildings in prime locations, primarily
in Southern California. The Company's portfolio, including the Pending
Acquisitions (as defined), is comprised of 33 suburban office buildings (the
"Office Properties"), encompassing approximately 2.9 million rentable square
feet, and 52 industrial buildings (the "Industrial Properties"), encompassing
approximately 3.6 million rentable square feet (collectively, the
"Properties"). All but eight of the buildings are located in Southern
California. As of June 30, 1997, the Office Properties were 88.1% leased to 166
tenants, and the Industrial Properties were 97.4% leased to 166 tenants. Since
completion of its IPO (as defined) in January 1997, the Company has acquired or
presently expects to complete the acquisition of an aggregate of 19 suburban
office buildings, encompassing an aggregate of approximately 900,000 rentable
square feet, and 40 industrial buildings, including the Pending Acquisitions,
encompassing approximately 2.2 million rentable square feet (collectively, the
"Acquired and Pending Properties"), for an aggregate acquisition cost of
approximately $255.7 million. The Company is self-administered and self-managed
and expects to qualify as a real estate investment trust ("REIT") beginning
with the tax year ending December 31, 1997.

All of the shares of common stock of the Company, par value $.01 per share (the
"Common Stock"), offered hereby are being sold by the Company (the "Offering").
To assist the Company in maintaining its qualification as a REIT for federal
income tax purposes, ownership by any person generally is limited to 7.0% of
the then outstanding Common Stock, which limit can be waived by the Board of
Directors. See "Description of Capital Stock--Restrictions on Ownership and
Transfer."

The Common Stock is listed on the New York Stock Exchange (the "NYSE") under
the symbol "KRC." On August 14, 1997, the last reported sales price of the
Common Stock on the NYSE was $25.50 per share. See "Price Range of Common
Stock and Distribution History." See "Glossary" beginning on page 174 for
definitions of certain terms used in this Prospectus.

SEE "RISK FACTORS" ON PAGES 24 TO 39 FOR A DISCUSSION OF CERTAIN MATERIAL
FACTORS WHICH SHOULD BE CONSIDERED IN CONNECTION WITH AN INVESTMENT IN THE
COMMON STOCK OFFERED HEREBY, INCLUDING:

. Conflicts of interest with, and material benefits to, affiliates of the
Company, including certain officers and directors, in connection with the
operation of the Company's ongoing businesses, including conflicts
associated with the tax consequences of sales and refinancings of the
Company's properties.

. Taxation of the Company as a corporation if it fails to qualify as a REIT
for federal income tax purposes and the resulting decreases in cash
available for distribution.

. The inability of the Company to control the operations of Kilroy Services,
Inc., which could result in decisions that do not reflect the Company's
interest.

. A portion of the Company's anticipated cash flow may be generated from
development activities which are partially dependent on the availability of
development opportunities, and are subject to the risks inherent with
development, which in turn may negatively impact the Company's ability to
make distributions.

. Dependence on demand for office and industrial space in the Southern
California market, thereby increasing the risk that the Company will be
materially adversely affected by general economic conditions in a single
market.

. Dependence on certain significant tenants, particularly Hughes Electronics
Corporation's Space & Communications Company, thereby increasing the
potential negative impact to the Company of downturns in the business of, or
its relationship with, such tenants.

. The distribution requirements of REITs may limit the Company's ability to
finance future developments, acquisitions and expansions without additional
debt or equity financing necessary to achieve the Company's business plan,
which in turn may adversely affect the price of the Common Stock.

GENERAL

Kilroy Realty Corporation and its Subsidiaries are engaged in the business of
owning, acquiring, developing, managing and leasing principally Class A
suburban office and industrial buildings in prime locations, primarily in
Southern California, continuing the 50-year real estate business established by
the Kilroy Group. The Company's portfolio, including the Pending Acquisitions
discussed below, is comprised of 33 suburban office buildings (the "Office
Properties"), encompassing approximately 2.9 million rentable square feet, and
52 industrial buildings (the "Industrial Properties"), encompassing
approximately 3.6 million rentable square feet (collectively, the
"Properties"). All but eight of the Properties are located in Southern
California. As of June 30, 1997, the Office Properties were 88.1% leased to 166
tenants (95.3% leased giving effect to the lease with The Boeing Company
("Boeing") which was executed in June 1997, and which provides for occupancy by
December 31, 1997 (the "Boeing Lease")), and the Industrial Properties were
97.4% leased to 166 tenants. The Company is self-administered and self-managed
and expects to qualify as a REIT beginning with the tax year ending December
31, 1997.

RECENT DEVELOPMENTS

Since completion of the initial public offering of its Common Stock (the
"IPO"), the Company successfully has implemented its growth strategy through
the following activities.

. Acquisitions. The Company acquired or presently expects to complete the
acquisition of an aggregate of 19 suburban office buildings encompassing
approximately 900,000 rentable square feet and 40 industrial buildings
encompassing approximately 2.2 million rentable square feet
(collectively, the "Acquired and Pending Properties"), representing an
aggregate investment of $255.7 million and increasing the Company's
aggregate rentable square feet of office and industrial space since the
date of its IPO by approximately 43.0% and 166.0% respectively.

. Leasing. In June 1997, the Company entered into a lease with Boeing for
approximately 211,000 rentable square feet of available office space at
Kilroy Airport Center, SeaTac (the "SeaTac Office Center").

1
<PAGE>

. Enhanced Management Team. The Company added five officers to enhance the
strength of its management team in the areas of acquisition, property
management and finance. These officers collectively have an average of
12 years of experience in the real estate industry.

. Finance. The Company entered into a revolving credit facility, with a
present commitment of $200.0 million, enhancing the Company's ability to
finance its property acquisition program and providing additional
working capital.

As a result of these activities, the Company believes that it is well
positioned to continue its growth strategies.

ACQUISITIONS

Since the completion of its IPO, the Company acquired 19 suburban office
buildings encompassing approximately 900,000 rentable square feet for an
aggregate acquisition cost (including expenses, closing costs and anticipated
capital expenditures) of $107.9 million, and 29 industrial buildings
encompassing approximately 1.5 million rentable square feet for an aggregate
acquisition cost (including expenses, closing costs and anticipated capital
expenditures) of approximately $90.3 million. As of the date of this
Prospectus, the Company is under contract to acquire and expects to complete
the acquisition of 11 additional industrial buildings encompassing
approximately 697,000 rentable square feet for an acquisition cost (including
expenses, closing costs and anticipated capital expenditures) of approximately
$57.5 million (the "Pending Acquisitions"). All but four of the buildings
comprising the Acquired and Pending Properties are located in Southern
California. Of the Acquired and Pending Properties, 28 buildings are located in
submarkets in which the Company already owned office or industrial property at
the completion of its IPO, and 31 buildings are located in new submarkets
within Los Angeles County, Northern Orange County, Southern Orange County,
Western San Bernardino County, Northern San Diego County, Santa Clara County
and Placer County. See "Business and Properties--The Company's Principal
Southern California Submarkets." As a result of these acquisitions (assuming
and giving effect to the completion of the Pending Acquisitions), the Company's
aggregate rentable square feet of office and industrial space increased by
approximately 43.0% and 166.0%, respectively. In addition, the Company is
currently in active negotiations to purchase an additional eight buildings all
of which are in Southern California (the "Pipeline Properties") for an
aggregate acquisition cost (including expenses, closing costs and anticipated
capital expenditures) of approximately $68.0 million, including the assumption
of $14.0 million of mortgage indebtedness. No assurance can be given that the
Pending Acquisitions or the acquisition of any of the Pipeline Properties will
be consummated. See "Risk Factors--Real Estate Investment Considerations--Risks
of Real Estate Acquisitions and Development" and "Business and Properties--
Acquired Properties" and "--Pending Acquisitions."

On July 30, 1997, the Company signed a non-binding letter of intent (the
"Allen LOI") with The Allen Group ("Allen") to acquire the principal assets of
Allen which include approximately 1.7 million rentable square feet of completed
and under construction office and industrial properties, and developable land,
located primarily in Northern San Diego County. If consummated, the Company
would purchase the assets in phases over the next several years for a total
investment currently estimated to exceed $300 million. The acquisition is
subject to the completion of due diligence and the negotiation of final
documentation. No assurance can be given that the transactions contemplated by
the Allen LOI will be consummated or, if consummated, successfully managed
and/or developed by the Company. See "Risk Factors--Real Estate Investment
Considerations--Risks of Real Estate Acquisition and Development," "--Real
Estate Financing Risks" and "Business and Properties--The Allen Group Letter of
Intent."

LEASING

In June 1997, the Company entered into a lease with Boeing for approximately
211,000 rentable square feet of office space at the SeaTac Office Center. The
seven-year lease to Boeing provides for occupancy by December 31, 1997. As of
June 30, 1997, approximately 96,000 rentable square feet of office space was
still available at the SeaTac Office Center. In addition, during the fourth
quarter of 1996, the Company entered into certain lease transactions with
respect to certain other Properties pursuant to which the tenants under the
respective leases began occupancy in the first quarter of 1997.

ENHANCED MANAGEMENT TEAM

Since the consummation of the IPO, the Company has added several key
experienced executives to its management team. Collectively, the new officers
have an average of 12 years of experience in the real estate industry. Alan S.
Pekarcik joined the Company in March 1997 as Senior Vice President,
Acquisitions. Previously, Mr. Pekarcik worked for 17 years as a real estate
broker in Southern California. Tyler H. Rose joined the Company in March 1997
as Senior Vice President and Treasurer. Prior to joining the Company, Mr. Rose
was Senior Vice President, Corporate Finance and Treasurer of Irvine Apartment
Communities and, prior to that, spent eight years in corporate finance at J.P.
Morgan & Co. Ann Marie Whitney was appointed Vice President and Controller of
the Company in May 1997 after spending eight years at Deloitte & Touche LLP,
most recently as a manager specializing in real estate. John T. Fucci and James
P. Axtell joined the Company in July 1997 as Vice President, Asset Management
and Director, Asset Management, respectively. Mr. Fucci, who has 14 years of
experience in property management, was previously a director at Catellus
Development Corporation. Mr. Axtell joined the Company from the Mission Land
Company. The Company believes that these new executives significantly augment
the real estate and finance experience of the management team. See
"Management."

FINANCE

For the five-month period beginning February 1, 1997 (following consummation
of the IPO) and ending June 30, 1997, the Company had revenues of $23.5
million, net income of $6.8 million or $0.47 per share, and Funds from
Operations of $13.0 million. For the three-month period ending June 30, 1997,
the Company had revenues of $14.6 million, net income of $4.1 million or $0.28
per share, and Funds from Operations of $8.0 million. For the two-month period
from February 1, 1997 to March 31, 1997, the Company achieved total revenues of
approximately $8.9 million, net income of approximately $2.7 million and Funds
from Operations of approximately $5.0 million. On May 30, 1997, the Company
paid a distribution to its stockholders of $0.2583 per share for the two-month
period from February 1, 1997 through March 31, 1997. On July 10, 1997, the
Company paid a distribution to its stockholders of $0.3875 per share for the
quarter ended June 30, 1997. The Operating Partnership made equal distributions
to its Unitholders with respect to each of the respective periods.

On July 22, 1997, the Company received a commitment to increase its secured
revolving line of credit to $200.0 million from $150.0 million (the "Credit
Facility"). The Credit Facility matures in May 1999 and is underwritten by
Morgan Guaranty Trust Company of New York ("MGT"). The Credit Facility is used
to finance property acquisitions and development and for general corporate
purposes. The facility bears interest at a variable rate equal to the 30-day
London interbank offered rate ("LIBOR") plus 1.50% and includes a one-year
option to extend the term. Upon completion of this Offering and the application
of the use of the estimated net proceeds therefrom, all outstanding borrowings
under the Credit Facility will be repaid. In addition, on August 13, 1997, the
Company amended the $12.0 million loan secured by the SeaTac Office Center to
increase the total principal amount outstanding to $14.0 million (the "SeaTac
Loan"). See "Management's Discussion and Analysis of Financial Condition and
Results of Operations--Liquidity and Capital Resources" and "Description of
Indebtedness."

OTHER ACTIVITIES

The Company currently owns or has exclusive rights to develop approximately
60 acres of developable land in six of its existing submarkets. The Company
intends to commence development of three projects in 1997 which comprise an
aggregate of approximately 500,000 rentable square feet at a total budgeted
cost of approximately $25.0 million. See "Business and Properties--Development,
Leasing and Management Activities."

THE COMPANY

Kilroy Realty Corporation was incorporated in September 1996 and commenced
operations upon the completion of its initial public offering on January 31,
1997. The Company was formed to continue and expand the real estate business of
the Kilroy Group, which, since 1947, has been engaged in the business of real
estate ownership, acquisition, development, leasing and management of
principally Class A suburban office and industrial buildings in prime
locations, primarily in Southern California. On January 31, 1997, the Company
completed an initial public offering of 12,500,000 shares of Common Stock. The
initial public offering price was $23.00 per share resulting in gross proceeds
of $287.5 million. On February 4, 1997, in connection with the initial public
offering, the underwriters exercised an over-allotment option and on February
7, 1997, pursuant to the terms of such over-allotment option, the Company
issued an additional 1,875,000 shares of Common Stock which resulted in gross
proceeds of $43,125,000. The aggregate proceeds to the Company of the IPO,
including the exercise of the underwriters' over-allotment option, net of
underwriters' discounts and commissions, advisory fees and offering costs, were
approximately $302.8 million. The Company operates as a self-administered and
self-managed real estate company and expects to qualify as a REIT for federal
and state income tax purposes beginning with the year ended December 31, 1997.
See "Federal Income Tax Consequences--Taxation of the Company."

The Company's strategy has been to own, develop, acquire, lease and manage
Class A suburban office and industrial properties in select locations in key
suburban submarkets, primarily in Southern California, that the Company
believes have strategic advantages compared to neighboring submarkets. The
Properties offer tenants: (i) lower business taxes and operating expenses than
in adjoining submarkets; (ii) access to highly skilled labor markets; (iii)
strategic access to major transportation facilities such as freeways and
airports; (iv) proximity to the Los Angeles-Long Beach port complex, which
presently ranks as the largest commercial port in the United States; and (v)
for tenants with their names on certain Properties, visibility to freeway and
airplane travelers. As a result, the Properties attract major corporate tenants
and historically have achieved among the highest occupancy, tenant retention
and rental rates, both within their respective submarkets and as compared to
their respective neighboring submarkets. See "Business and Properties."

The Company's portfolio of properties includes 33 office buildings
encompassing an aggregate of approximately 2.9 million rentable square feet and
52 industrial buildings encompassing an aggregate of approximately 3.6 million
rentable square feet. Thirty of the office buildings and 47 of the industrial
buildings are located in prime Southern California suburban submarkets
(including a complex of three office buildings located in El Segundo, adjacent
to the Los Angeles International Airport ("LAX"), presently the nation's second
largest air-cargo port, and a complex of five office buildings located adjacent
to the Long Beach Municipal Airport (the "Long Beach Airport")). The SeaTac
Office Center is comprised of three office buildings located adjacent to the
Seattle-Tacoma International Airport. The weighted average age of the Office
Properties is approximately 14 years and the weighted average age of the
Industrial Properties is approximately 18 years. As of June 30, 1997, the
Office Properties were approximately 88.1% leased to 166 tenants, and the
Industrial Properties were approximately 97.4% leased to 166 tenants.

The Company's major tenants include, among others, Hughes Electronics
Corporation's Space & Communications Company ("Hughes Space & Communications"),
a tenant since 1984, which is engaged in high-technology commercial activities
including satellite development and related applications such as DirecTV, and
other major tenants such as Sony Music Entertainment, Boeing (giving effect to
the Boeing Lease), M/R Systems, Mattel, Inc., Northwest Airlines, Inc. and
Caltrans. The Company's strong relationships with its tenants are evidenced by
its average tenant retention rate (based upon rentable square feet) for the
period beginning January 1, 1994 and ending June 30, 1997, which was 74.1% for
the Properties owned as of the date of the IPO that were located in the
counties of Los Angeles, Orange, Riverside, San Bernardino and Ventura.

Since the completion of its IPO, the Company acquired or presently expects to
complete the acquisition of an aggregate of 19 suburban office buildings
encompassing approximately 900,000 rentable square feet for an aggregate
acquisition cost (including expenses, closing costs and anticipated capital
expenditures) of approximately $107.9 million, and 40 industrial buildings
encompassing approximately 2.2 million rentable square feet for an aggregate
acquisition cost (including expenses, closing costs and anticipated capital
expenditures) of approximately $147.8 million. For one Acquired Property, the
acquisition cost was paid, in part, with the issuance of 165,102 limited
partnership units in the Operating Partnership. The issuance of the units in
the Operating Partnership ("Units") permits sellers of properties to defer the
recognition of all or part of the taxable gain, if any, on the disposition of
such properties. All but four of the Acquired and Pending Properties are
located in Southern California. Of the Acquired and Pending Properties, 28
buildings are located in submarkets in which the Company already owned office
or industrial property at the completion of the IPO, and 31 buildings are
located in new submarkets within Los Angeles County, Northern Orange County,
Southern Orange County, Western San Bernardino County, Northern San Diego
County, Santa Clara County and Placer County. Management believes that each of
these new submarkets offers significant growth opportunities. See "Business and
Properties--The Company's Principal Southern California Submarkets." As a
result of these acquisitions, the Company's aggregate rentable square feet of
office and industrial space increased by approximately 43.0% and 166.0%,
respectively. In addition, the Company is currently in active negotiations to
purchase eight Pipeline Properties, all of which are located in Southern
California, for an aggregate acquisition cost of approximately $68.0 million,
including the assumption of $14.0 million of mortgage indebtedness. No
assurance can be given that the Pending Acquisitions or the acquisition of the
Pipeline Properties will be consummated. See "Risk Factors--Real Estate
Investment Considerations--Risks of Real Estate Acquisitions and Development"
and "Business and Properties--Acquired Properties" and "--Pending
Acquisitions."

The Company currently owns or has exclusive rights to develop approximately
60 acres of developable land (net of the acreage required for streets),
including (i) ten acres in Brea, California, (ii) 15 acres in Foothill Ranch in
Orange County, California, (iii) two and one-half acres in Anaheim, California,
(iv) three and one-half acres in Irvine, California, (v) five acres in
Camarillo, California and (vi) 24 acres at Kilroy Airport Center Long Beach
(collectively, the "Development Properties"). Management believes that it can
build up to 1.6 million rentable square feet on the Development Properties,
subject to required entitlements and other governmental approvals, of which
approximately 500,000 rentable square feet is planned for development beginning
in 1997. The Company may engage in the development of office or industrial
properties when market conditions support a favorable risk-adjusted rate of
return on such development. No assurance can be given that the Company will
commence any development, or that, if commenced, any such development will be
completed. See "Risk Factors--Real Estate Investment Considerations--Risks of
Real Estate Acquisition and Development" and "Business and Properties--
Development, Leasing and Management Activities--Kilroy Airport Center, Long
Beach."

The Company believes, based on independent economic surveys, that the office
and industrial real estate market in the Southern California five-county region
encompassing the counties of Los Angeles, Orange, Riverside, San Bernardino and
Ventura (the "Southern California Area") is recovering after experiencing a
downturn over the last several years. Vacancy rates in the Class A office space
market in the Southern California Area have decreased from a high of nearly
20.0% in 1991 and 1992 to under 17.0% at the end of 1996. Vacancy rates in the
industrial space market in the Southern California Area have also decreased
from a high of nearly 14.0% in 1992 to 7.6% at the end of 1996. See "--The
Company's Principal Southern California Submarkets." Management believes that
the ongoing economic recovery in its submarkets will continue the trend of
increasing occupancy rates and should apply some upward pressure on rents for
Class A office buildings and industrial buildings. See "--Growth Strategies"
and "The Company--Growth Strategies."

senior management team and its long-term relationships with large Southern
California corporate tenants, municipalities, landowners and institutional
sellers. In addition, the Company believes that it is one of a limited number
of REITs focusing on office and industrial properties and that it is the only
REIT with a 50-year operating history concentrating primarily on the
acquisition and development of suburban Southern California office and
industrial properties.

During the remainder of the Company's first year of operations, the Company
expects sources of potential growth in cash available for distribution through:
(i) the further leasing of its available space of approximately 230,000
rentable square feet, as of June 30, 1997; (ii) the renewal of leases at higher
rents; and (iii) the acquisition of strategic properties with Units and/or
available cash and borrowings under the Credit Facility and the Company's
approximately $88.8 million of cash available for acquisitions and property
development upon consummation of the Offering. In the Company's second year of
operations, the Company expects sources of potential growth in cash available
for distribution through: (i) contractual increases in base rent payments from
tenants; (ii) continued leasing of available space; (iii) the acquisition of
strategic properties; and (iv) the contemplated completion of certain
development activities. Although the Company paid distributions to holders of
its Common Stock for the periods ended March 31 and June 30, 1997, there can be
no assurance that the Company will achieve any growth in cash available for
distribution, that available space will be leased, that leases scheduled to
expire will be renewed or that the Company will successfully acquire additional
properties or complete any of its planned development activities. See "Risk
Factors--Real Estate Investment Considerations--Risks of Real Estate
Acquisition and Development."

As of June 30, 1997, the Company (primarily through the Operating Partnership
and the Services Company) employed 58 persons, 43 of whom are located at the
Company's headquarters at Kilroy Airport Center in El Segundo, California. The
Company believes that relations with its employees are good. The Company's
executive officers have been with the Company for an average of approximately
13 years. As of June 30, 1997, after giving effect to the Offering, the
Company's executive officers and directors (and certain of their affiliates)
owned in the aggregate 10.1% of the Common Stock (or interests exchangeable
therefor).

RISK FACTORS

When used in this Prospectus, the words "may," "will," "expect,"
"anticipate," "continue," "estimate," "project," "intend" and similar
expressions are intended to identify forward-looking statements within the
meaning of Section 27A of the Securities Act of 1933, as amended (the
"Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), regarding events, conditions and financial trends
that may affect the Company's future plans of operations, business strategy,
results of operations and financial position. Prospective investors are
cautioned that any forward-looking statements are not guarantees of future
performance and are subject to risks and uncertainties and that actual results
may differ materially from those included within the forward-looking statements
as a result of various factors. Factors that could cause or contribute to such
differences include, but are not limited to, those described below, under the
heading "Management's Discussion and Analysis of Financial Condition and
Results of Operations" and elsewhere in this Prospectus.

An investment in the shares of Common Stock involves various material risks.
Prospective investors should carefully consider the following risk factors, in
addition to the other information set forth in this Prospectus, before making
an investment decision regarding the shares of Common Stock offered hereby.
Each of these matters could have adverse consequences to the Company. Such
risks include, among others:

. conflicts of interest, particularly with the limited partners (including
John B. Kilroy, Sr. and John B. Kilroy, Jr.) of the Operating
Partnership (the "Unitholders") who hold units therein ("Units"),
including members of the Kilroy Group, in connection with the (i)
operation of the Company's ongoing businesses, including conflicts
associated with the tax consequences to certain Unitholders who are
limited partners of sales or refinancings of certain Properties, which,
together with provisions of the

7
<PAGE>

agreement of the Operating Partnership (the "Partnership Agreement"),
may influence the Company's decision to sell or refinance, or to prepay
debt secured by, certain Properties, (ii) potential election by the
Company to exercise its option to purchase any of the properties owned
or controlled by one or more of the Unitholders who are limited partners
which the Company has the option to acquire (the "Option Properties")
and (iii) enforcement of agreements with affiliates of the Company, any
of which could result in decisions affecting the Company that do not
fully reflect interests of all of the Company's stockholders;

. limitations on Kilroy Realty Corporation's ability to withdraw as
general partner of the Operating Partnership, transfer or assign its
interest in the Operating Partnership without the consent of the holders
of at least 60% of the Units (including Units held by Kilroy Realty
Corporation which, after giving effect to the Offering and the
contribution of the estimated net proceeds to the Operating Partnership,
represent 89.7% of all Units outstanding) and without meeting certain
criteria with respect to the consideration to be paid to the
Unitholders, or to dissolve the Operating Partnership or sell the Office
Property located at 2260 E. Imperial Highway, El Segundo, California, at
Kilroy Airport Center at El Segundo without the consent of more than 50%
of the Units held by limited partners (excluding Units held by Kilroy
Realty Corporation), which may in each case result in the Company taking
action that is not in the best interest of all stockholders;

. taxation of the Company as a corporation if it fails to qualify as a
REIT for federal income tax purposes, the Company's liability for
certain federal, state and local income taxes in such event and the
resulting decrease in cash available for distribution;

. the possibility that acquisitions of office or industrial properties,
including the Pending Acquisitions and the consummation of the
transactions contemplated by the Allen LOI, will fail to be consummated,
or that any such acquired properties will fail to perform in accordance
with management's expectations, including the possibility that estimates
of the costs of improvements to bring an acquired property up to
standards established for the market position intended for that property
may prove inaccurate;

. the inability of the Company to control the operations of the Services
Company, which could result in decisions that do not reflect the
Company's interest because the Company does not control the election of
directors or the selection of officers of the Services Company;

. a portion of the Company's anticipated cash flow may be generated from
development activities, which are partially dependent on the
availability of development opportunities, and are subject to the risks
inherent in development as well as general economic conditions and
limitations on such activities imposed by the REIT tests, which in turn
may negatively impact the Company's ability to make distributions;

. geographic concentration of 77 of the Company's 85 buildings (including
the Pending Acquisitions) in Southern California, creating a dependence
on demand for office and industrial space in such market and increasing
the risk that the Company will be materially adversely affected by
general economic conditions in a single market;

. the Company's results of operations are dependent on certain key
tenants, particularly Hughes Space & Communications, which accounted for
approximately 15.9% of the Company's total base rent for the year ended
December 31, 1996 giving pro forma effect to the acquisition of the
Acquired and Pending Properties and the Boeing Lease, thereby increasing
the potential negative impact to the Company of downturns in the
business of, or its relationship with, such tenants. The base periods of
the Hughes Space & Communications' leases expire beginning in January
1999;

. the distribution requirements for REITs under federal income tax laws
may limit the Company's ability to finance future acquisitions,
developments and expansions without additional debt or equity financing
and may limit cash available for distribution;

. real estate investment considerations such as the effect of economic and
other conditions on real estate values, the general lack of liquidity of
investments in real estate, the ability of tenants to pay rents, the

8
<PAGE>

possibility that leases may not be renewed or will be renewed on terms
less favorable to the Company, the possibility of uninsured losses,
including losses associated with earthquakes, the ability of the
Properties to generate sufficient cash flow to meet operating expenses,
including debt service, and competition in seeking properties for
acquisition and in seeking tenants, which, individually or in the
aggregate, may negatively impact the Company's ability to make
distributions;

. risks associated with debt financing, including the potential inability
to refinance mortgage indebtedness upon maturity and the potential
increase in the level of indebtedness incurred by the Company since its
organizational documents do not limit the amount of indebtedness which
the Company may incur, which may adversely affect the ability of the
Company to repay debt, particularly in the event of a downturn in the
Company's business;

. substantial influence over the affairs of the Company by certain
Unitholders who are directors and executive officers of the Company, and
the ability of the Company's board of directors (the "Board of
Directors") to change the investment policies of the Company (including
the Company's ratio of debt to total market capitalization) without the
consent of stockholders, which may result in a decline in the market
value of the Common Stock;

. potential anti-takeover effects of provisions generally limiting the
actual or constructive ownership by any one person or entity of Common
Stock to 7.0% of the outstanding shares, a classified board of directors
and other charter and statutory provisions and provisions in the
Partnership Agreement that may have the effect of inhibiting a change of
control of the Company or making it more difficult to effect a change in
management or limiting the opportunity for stockholders to receive a
premium over the market price for the Common Stock;

. dependence on key personnel;

. the Company's cash available for distribution may be less than the
Company expects and may decrease in future periods from historical
levels, materially adversely affecting the Company's ability to sustain
its historical distribution rate in the future;

. the Company's historical operating losses for financial reporting
purposes;

. the ability of the Company to incur more debt, thereby increasing its
debt service, which could adversely affect the Company's cash flow;

. the potential liability of the Company for environmental matters and the
costs of compliance with certain governmental regulations, which may
negatively impact the Company's financial condition, results of
operations and cash available for distribution;

. the public market for the shares of Common Stock might not be
maintained, which may negatively impact the price at which shares of
Common Stock may be resold;

. potential adverse effects on the value of the shares of Common Stock of
fluctuations in interest rates or equity markets, which may negatively
impact the price at which shares of Common Stock may be resold and may
limit the Company's ability to raise additional equity to finance
acquisitions and future development; and

. the possible issuance of additional shares of Common Stock, including
2,817,476 shares of Common Stock issuable upon exchange of the Units
presently outstanding, which may adversely affect the market price of
the shares of Common Stock or result in dilution on a per share basis of
cash available for distribution.

FORMATION AND STRUCTURE OF THE COMPANY

Kilroy Realty Corporation was formed in September 1996, and the Operating
Partnership was formed in October 1996. The Services Company was formed in
January 1997 to succeed to the development activities of the Kilroy Group and
to perform development activities for the Company and third parties, and the
Finance Company and the Finance Partnership were formed in January 1997 in
connection with the $84.0 million mortgage loan (the "$84.0 Million Loan").
Concurrent with the consummation of the IPO, the Company and the Unitholders
who are members of the Kilroy Group engaged in certain transactions (the
"Formation Transactions"), designed to enable the Company to continue and
expand the real estate operations of the Kilroy Group, to facilitate the IPO,
to enable the Company to qualify as a REIT for federal income tax purposes
commencing with its taxable year ending December 31, 1997 and to preserve
certain tax advantages for certain Unitholders. Certain Unitholders, including
members of management, some of whom are also directors, received benefits in
connection with the IPO and the Formation Transactions. See "Formation and
Structure of the Company--Formation Transactions."

Kilroy Realty Corporation's operations are conducted through its
subsidiaries. Kilroy Realty Corporation is the sole general partner of the
Operating Partnership and the remaining Unitholders are limited partners. See
"Formation and Structure of the Company--Formation Transactions."

After giving effect to the Offering, all of the net proceeds of which will be
contributed to the Operating Partnership for additional Units, Kilroy Realty
Corporation will own a 89.7% general partner interest in the Operating
Partnership and will continue to be its sole general partner. The remaining
10.3% interest in the Operating Partnership will be owned by the remaining
Unitholders, all of which are limited partners. All of the limited partnership
Units are redeemable for cash or, if requested by the Unitholder, and at the
Company's option, exchangeable for shares of Common Stock on a one-for-one
basis, subject to certain anti-dilution adjustments and certain other
exceptions, beginning January 31, 1999 (other than certain holders who are
corporations or limited liability companies who may require the Company to
issue shares of Common Stock in lieu of cash). Assuming the exchange of all
outstanding limited partnership Units for shares of Common Stock, and after
giving effect to the Offering, the Company's executive officers and directors,
and Unitholders who are members of the Kilroy Group, will own approximately
10.1% of the Common Stock.

The Finance Company is a wholly-owned subsidiary of the Kilroy Realty
Corporation and serves as the 1.0% sole general partner of the Finance
Partnership. The Operating Partnership is the 99.0% limited partner of the
Finance Partnership. The Finance Partnership is the obligor on the $84.0
Million Loan and the owner of the Properties that secure such indebtedness. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources" and "Business and Properties--
Mortgage Debt."

John B. Kilroy, Sr. and John B. Kilroy, Jr. together own 100.0% of the voting
common stock of the Services Company, representing 5.0% of its economic value.
The Operating Partnership owns 100.0% of the nonvoting preferred stock of the
Services Company, representing 95.0% of its economic value. The ownership
structure of the Services Company is necessary to permit the Company to share
in the income of the activities of the Services Company and also maintain its
status as a REIT. Although the Company receives substantially all of the
economic benefit of the businesses carried on by the Services Company through
the Company's right to receive dividends through the Operating Partnership's
investment in the Services Company's nonvoting preferred stock, the Company is
not able to elect the Services Company's officers or directors, and
consequently may not have the ability to influence the operations of the
Services Company. See "Risk Factors--Risk of Development Business and Related
Activities Being Conducted by the Services Company--Adverse Consequences of
Lack of Control Over the Businesses of the Services Company."

and its Subsidiaries (giving effect to this Offering and the application of the
net proceeds therefrom):

[CHART APPEARS HERE]

GROWTH STRATEGIES

The Company's objectives are to maximize growth in cash available for
distribution and to enhance the value of its portfolio through effective
management, operating, acquisition and development strategies. The Company
believes that opportunities exist to increase cash available for distribution:
(i) by acquiring office and industrial properties with attractive returns in
strategic suburban submarkets where such properties complement its existing
portfolio; (ii) from contractual increases in base rent; (iii) as a result of
increasing rental and occupancy rates and decreasing concessions and tenant
installation costs; and (iv) by developing properties for the benefit of the
Company where such development will result in a favorable risk-adjusted return
on investment. The Company's ability to achieve its growth strategy will be
aided by its available cash of approximately $88.8 million upon consummation of
the Offering.

The Company believes that a number of factors will enable it to achieve its
business objectives, including: (i) the opportunity to lease available space at
attractive rental rates because of increasing demand and, with respect to
office properties, the present lack of new construction in the Southern
California submarkets in which most of the Properties are located; (ii) the
presence of inadvertent owners (through foreclosure or otherwise) of office and
industrial properties in the Company's submarkets, as well as the Company's
ability to acquire

11
<PAGE>

properties with Units (thereby permitting a seller to defer taxable gain), both
of which create enhanced acquisition opportunities; (iii) the quality and
location of the Properties; and (iv) the Company's access to acquisition and
development opportunities as a result of its significant relationships 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 exploit 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. In addition, the Company
believes that public ownership and its conservative capital structure will
provide new opportunities for growth. There can be no assurance, however, that
the Company will be able to lease available space, complete any property
acquisitions, successfully develop any land acquired or improve the operating
results of any developed properties that are acquired. See "Business and
Properties--Development, Leasing and Management Activities."

Operating Strategies. The Company focuses on enhancing growth in cash
available for distribution by: (i) maximizing cash flow from the Properties
through active leasing, contractual base rent increases and effective property
management; (ii) managing operating expenses through the use of in-house
management, leasing, marketing, financing, accounting, legal, construction
management and data processing 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 markets.

The Company believes that the strength of its leasing is demonstrated by the
Company's leasing activity since 1993. In the period from January 1, 1993 to
June 30, 1997, the Company leased or renewed leases for an aggregate of
approximately 1.2 million rentable square feet of office space and
approximately 786,000 rentable square feet of industrial space. As of June 30,
1997, the Office Properties located in Southern California were approximately
98.3% leased. As of March 31, 1997, occupancy rates for all office properties
were approximately 83.7% for Southern California, and, as of June 30, 1997, the
Industrial Properties in Southern California were approximately 97.0% leased as
compared to 92.7% for all industrial properties located in Southern California
as of March 31, 1997. See "Business and Properties--General" and "--Occupancy
and Rental Information."

The Company's 20 largest tenants represented approximately 54.0% of annual
base rent for the year ended December 31, 1996 (giving pro forma effect to the
Boeing Lease). Of this amount, its largest tenant, Hughes Space &
Communications, currently leases approximately 530,000 rentable square feet of
office space, representing approximately 15.9% of the Company's total base rent
for the year ended December 31, 1996 giving pro forma effect to the Acquired
and Pending Properties and the Boeing Lease. The base periods of the Hughes
Space & Communications leases expire beginning in January 1999. The Company's
revenues and cash available for distribution to stockholders would be
disproportionately and materially adversely affected in the event of bankruptcy
or insolvency of, or a downturn in the business of, or the nonrenewal of leases
by, any of its significant tenants, or the renewal of such leases on terms less
favorable to the Company than their current terms.

Approximately 1.0 million aggregate rentable square feet in the Properties,
owned by the Company as of the date of its IPO, was leased by the Company from
January 1, 1992 through December 31, 1994, a period which management
characterizes as recessionary. Based on the leases the Company signed in 1996,
and the findings in an independent study of the Southern California real estate
market commissioned by the Company, management believes that the recent trend
toward increasing rental rates in Class A office and industrial buildings in
the Company's Southern California submarkets presents significant opportunities
for growth. In addition, as of June 30, 1997, approximately 58.5% of the
Company's rentable square feet is subject to leases expiring in 2000 or beyond,
when management expects asking rents for the respective Properties to be higher
than the rents paid pursuant to such leases. In addition, as of June 30, 1997,
approximately 20.6% of the Company's total base

12
<PAGE>

rent (representing approximately 10.2% of the aggregate rentable square feet of
the Properties) was attributable to leases with Consumer Price Index ("CPI")
increases and approximately 34.5% of the Company's total base rent
(representing approximately 37.7% of the aggregate rentable square feet of the
Properties) was attributable to leases with other specified contractual
increases. No assurance can be given, however, that new leases will reflect
rental rates greater than or equal to current rental rates or that current or
future economic conditions will support higher rental rates. See "Risk
Factors--Real Estate Investment Considerations."

Acquisition Strategies. The Company seeks to increase its cash available for
distribution by acquiring additional quality office and industrial properties,
including properties that: (i) may provide attractive initial yields with
significant potential for growth in cash flow from property operations; (ii)
are strategically located, of high quality and competitive in their respective
submarkets; (iii) are located in the Company's existing submarkets and/or in
other strategic submarkets where the demand for office and industrial space
exceeds available supply; or (iv) have been under-managed or are otherwise
capable of improved performance through intensive management and leasing that
will result in increased occupancy and rental revenues. The Company believes
that the Southern California market is an established and mature real estate
market in which property owners generally have a low tax basis (and,
accordingly, the potential for large taxable gains) in their properties.
Management believes that the Company's significant Southern California
relationships, extensive experience, conservative capital structure and ability
to acquire properties for Units, and thereby defer a seller's taxable gain, if
any, will enhance the ability of the Company to consummate transactions quickly
and to structure more competitive acquisitions than other real estate companies
in the market which lack its access to capital or the ability to issue Units.
See "Business and Properties--Development, Leasing and Management Activities."

As of June 30, 1997, the Company had entered into agreements to acquire the
Pending Acquisitions. The Pending Acquisitions are comprised of 11 industrial
buildings encompassing approximately 697,000 rentable square feet for an
aggregate acquisition cost of $57.5 million. Seven of the building are located
in Southern California. In addition, the Company is currently in active
negotiations to purchase eight Pipeline Properties for an aggregate acquisition
cost of $68.0 million, including the assumption of $14.0 million of mortgage
indebtedness. All of the Pipeline Properties are located in Southern
California. In addition, on July 30, 1997, the Company entered into the Allen
LOI. There can be no assurance, however, that the Company will be able to
complete any property acquisitions, successfully develop any land acquired or
improve the operating results of any developed properties that are acquired.
See "--Recent Developments--Acquisitions" and "Business and Properties--
Acquired Properties," "--Pending Acquisitions" and "--The Allen Group Letter of
Intent."

Development Strategies. Since 1947, the Company and its predecessors have
developed millions of rentable square feet of office and industrial space,
including high technology facilities, primarily located in Southern California,
for its own portfolio and for third parties. The Company currently owns an
aggregate of approximately 36 acres of developable land, comprised of ten acres
of developable land in Brea, 15 acres in Foothill Ranch in Orange County, two
and one-half acres in Anaheim, three and one-half acres in Irvine and five
acres in Camarillo. The Company is the master ground lessee of, and has sole
development rights to, the 24 acres of developable land entitled for office,
research and development, light industrial and other commercial projects at
Kilroy Airport Center, Long Beach. All of the developable land is located in
Southern California. Management believes that the aggregate 60 acres of
developable land provide the Company with significant growth opportunities.

The Company presently plans to develop an aggregate of up to 1.6 million
rentable square feet of office or industrial space on the Development
Properties, subject to required entitlements and other governmental approvals.
Of this amount, the Company plans to commence development of approximately
500,000 rentable square feet of industrial space in 1997 at a total budgeted
cost of approximately $25.0 million. No assurance can be given that the Company
will commence any development, or that, if commenced, any such development will
be completed. See "Risk Factors--Real Estate Investment Considerations--Risks
of Real Estate Acquisition and Development" and "Business and Properties--
Development, Leasing and Management Activities--Kilroy Airport Center, Long
Beach."

<PAGE>

The Company may engage in the development of other office and/or industrial
properties primarily in Southern California submarkets 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 Development Properties or any other properties. See "Business and
Properties--Development, Leasing and Management Activities."

Financing Policies. The Company's financing policies and objectives are
determined by the Board of Directors. The Company presently limits the 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) to approximately 50%.
However, such objectives may be altered 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. The total debt constituted,
as of June 30, 1997, approximately 29.9% of the total market capitalization of
the Company. Giving pro forma effect to the Offering and the application of the
estimated net proceeds from the Offering, total debt, as of July 31, 1997,
would have constituted approximately 12.1% of the total market capitalization
of the Company. The Company intends to utilize one or more sources of capital
for future acquisitions, development and capital improvements, which may
include undistributed cash flow, borrowings under the Credit Facility, the
Company's approximately $88.8 million of cash available for acquisition and
development out of the net proceeds of the Offering, 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 for any
such acquisitions, developments or improvements on terms favorable to the
Company. See "The Company--Growth Strategies" and "Business and Properties--
Development, Leasing and Management Activities."

THE PROPERTIES

The following table sets forth certain information relating to each of the
Properties as of December 31, 1996, unless indicated otherwise. This table
gives pro forma effect to (i) the November 1996 extension of one of the leases
with Hughes Space & Communications with respect to two of the office buildings
located at Kilroy Airport Center at El Segundo as if such lease renewal had
occurred on January 1, 1996 and (ii) the acquisition of the Acquired Properties
and the Pending Acquisitions, as if such acquisitions had occurred on January
1, 1996. The table does not, however, give effect to the lease of 211,000
rentable square feet of office space with Boeing at the SeaTac Office Center,
entered into as of June 20, 1997. During the fourth quarter of 1996, the
Company entered into certain lease transactions pursuant to which the tenants
under the respective leases began occupancy in the first six months of 1997.
Consequently, total occupancy data as of June 30, 1997 reflects the higher
occupancy as a result of these transactions which are reflected in the
Company's leasing activity for the year ended December 31, 1996, and not in
leasing activity for the first six months of 1997. See "Business and
Properties--General--Existing Office Properties" and "--Existing Industrial
Properties." The Company (through the Operating Partnership and Finance
Partnership) owns a 100% interest in all of the Properties other than the five
office buildings located at Kilroy Airport Center Long Beach and the three
office buildings located at the SeaTac Office Center, each of which are held
subject to ground leases expiring in 2035 and 2064 (assuming the exercise of
the Company's options to extend such lease), respectively.

(1) Represents the year built or the date of the most recent substantial
renovation. For Properties with multiple buildings, the year built refers
to the earliest date with respect to such buildings.
(2) Based on all leases at the respective Properties in effect as of December
31, 1996.

(footnotes continued on next page)

<PAGE>

(3) Total base rent for the year ended December 31, 1996, determined in
accordance with generally accepted accounting principles ("GAAP").
Substantially all leases at the Industrial Properties are written on a
triple net basis. Unless otherwise indicated, all leases at the Office
Properties are written on a full service gross basis, with the landlord
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"). Each tenant pays its pro rata share of
increases in expenses above the Base Year or Expense Stop.
(4) Aggregate base rent received over the respective lease term from all lease
transactions in effect at December 31, 1996 minus all tenant improvements,
leasing commissions and other concessions for all such leases, paid or
payable by the Company, divided by the terms in months for such leases,
multiplied by 12. Tenant improvements, leasing commissions and other
concessions are estimated using the same methodology used to calculate
effective rent for the Properties as a whole in the charts set forth under
the caption "Business and Properties--General."
(5) The percentage of 1996 total base rent is calculated as the base rent of
the respective Property for the year ended December 31, 1996 divided by
the combined base rent for all of the Properties (including the Acquired
Properties and the Pending Acquisitions) for the year ended December 31,
1996.
(6) Base rent for the year ended December 31, 1996 divided by rentable square
feet leased at December 31, 1996.
(7) Effective rent at December 31, 1996 divided by rentable square feet leased
at December 31, 1996.
(8) Based on all leases at the respective Properties dated on or before June
30, 1997.
(9) Excludes office space leased by the Company.
(10) For this Property, leases with Hughes Space & Communications, for
approximately 96,000 rentable square feet, and with SDRC Software Products
Marketing Division, Inc., for approximately 6,800 rentable square feet,
are written on a full service gross basis except that there is no Expense
Stop.
(11) For this Property, the lease with Hughes Space & Communications is written
on a modified full service gross basis under which Hughes Space &
Communications pays for all utilities and other internal maintenance costs
with respect to the leased space and, in addition, pays its pro rata share
of real estate taxes, insurance, and certain other expenses including
common area expenses.
(12) For this Property, leases with Hughes Space & Communications for
approximately 103,000 rentable square feet are written on a full service
gross basis except that there is no Expense Stop.
(13) For this Property, the lease is written on a triple net basis.
(14) The data does not reflect the lease of 211,000 rentable square feet of
office space with Boeing at the SeaTac Office Center, entered into as of
June 20, 1997 which provides for occupancy by December 31, 1997. See
"Business and Properties--Office Properties--Kilroy Airport Center,
SeaTac."
(15) This Industrial Property was vacant until April 1996. The tenant began
paying rent in mid-October 1996 at an annual rate of $4.40 per rentable
square foot.
(16) The tenant subleased this Industrial Property on May 15, 1996 to RGB
Systems, Inc. (doing business as Extron Electronics), the tenant of the
Property located at 1230 S. Lewis Street, Anaheim, California, which is
adjacent to this Property. The sublease is at an amount less than the
current lease rate, and the tenant is paying the difference between the
current lease rate and the sublease rate. The lease and the sublease
terminate in April 1998. Extron Electronics has executed a lease for this
space from May 1998 through April 2005 at the current lease rate. Extron
Electronics continues to occupy the space located at 1230 S. Lewis Street.
(17) This Industrial Property was originally designed for multi-tenant use and
currently is leased to a single tenant and utilized as an indoor multi-
vendor retail marketplace.
(18) The leases for this Industrial Property are written on a modified triple
net basis, with the tenants responsible for estimated allocated common
area expenses.
(19) As of the date of this Prospectus, the Company has not completed the
acquisition of this Property.
(20) The Brea Industrial Properties consist of 660 Puente Street, 1050 West
Central, 1150 West Central, 950 West Central, 895 Beacon Street,
955 Beacon Street and 1125 Beacon Street.
(21) The Garden Grove Industrial Properties consist of 12442 Knott Avenue, 7091
Belgrave Avenue, 12311-21 Industry Street, 12241-71 Industry Street, 7261
Lampson Avenue and 12472 Edison Way.
(22) Financial information for the year ended December 31, 1996, for 9401 and
9451 Toledo Way, Irvine, California is not available because the Property
was 100.0% owner-occupied. Concurrent with the Company's acquisition of
the Property, a lease was signed by the former owner for a continued
100.0% occupancy of the Property.
(23) Subsequent to June 30, 1997, this tenant terminated its lease and the
portion of the office space previously occupied by such tenant is now
available for lease.
(24) This Property is managed by third-party managers. See "Business and
Properties--Development, Leasing and Management Activities."

THE COMPANY'S SOUTHERN CALIFORNIA SUBMARKETS

In connection with the Offering, the Company retained Robert Charles Lesser &
Co. ("Lesser"), nationally recognized experts in real estate consulting and
urban economics, to study the Company's Southern California submarkets, and the
discussion of such submarkets below is based upon Lesser's findings. While the
Company believes that these estimates of economic trends are reasonable, there
can be no assurance that these trends will in fact continue.

The Properties are primarily located in Los Angeles, Orange and Ventura
Counties which, together with Riverside and San Bernardino Counties, comprise
the second largest Consolidated Metropolitan Statistical Area in the United
States. Management believes that the region's economy, which in 1994 commenced
recovery from a four-year economic recession, and the continuing growth in the
region's foreign trade, tourism and entertainment industries, provide an
attractive environment for owning and operating Class A office and industrial
properties since occupancy rates and asking rents generally are increasing. In
addition, since 1992 there has been virtually no increase in the region's
office space, while the region's demand for quality industrial space
accompanied by low vacancy rates has spurred modest new construction of
industrial properties.

Vacancy rates in the office space market in the Southern California Area are
trending downward from a high of nearly 20.0% in 1991 and 1992 to 16.3% at
March 31, 1997. As of June 30, 1997, the vacancy rate for the Company's
Southern California Office Properties was approximately 1.7%. Vacancy rates in
the industrial space market in the Southern California Area have decreased from
a high of nearly 14.0% in 1992 to approximately 7.3% at March 31, 1997. At June
30, 1997, the vacancy rate for the Company's Southern California Industrial
Properties was approximately 3.0%.

The Southern California Area population in 1996 was estimated at 15.7 million
people which accounted for approximately 5.9% of the total U.S. population.
Beginning in 1990, annual population growth in the region has averaged
approximately 192,000 persons. Of the total 1996 population, approximately 9.3
million and 2.6 million persons lived in Los Angeles and Orange Counties,
respectively, the counties in which all but 15 of the Properties are located.
Annual estimated growth in population over the next five years in these
counties is expected to be approximately 79,000 and 35,000 persons,
respectively. See "Business and Properties--The Company's Principal Southern
California Submarkets."

SUMMARY FINANCIAL DATA

The following table sets forth certain financial data on a historical and pro
forma basis for the Company, and on an historical basis for the Kilroy Group,
which consist of the Consolidated Financial Statements of Kilroy Realty
Corporation and the Combined Financial Statements of the Kilroy Group whose
financial results are consolidated in the historical and pro forma financial
statements of the Company (the "Consolidated and Combined Financial
Statements"). The financial data should be read in conjunction with the
historical and pro forma financial statements and notes thereto included in
this Prospectus. The combined historical summary financial data as of December
31, 1995 and 1996 and for each of the three years in the period ended December
31, 1996 have been derived from the Combined Financial Statements of the Kilroy
Group audited by Deloitte & Touche LLP, independent public accountants, whose
report with respect thereto is included elsewhere in this Prospectus. The
summary combined historical financial and operating information as of December
31, 1992, 1993 and 1994, and for the years ended December 31, 1992 and 1993,
the six months ended June 30, 1996, and the period from January 1, 1997 to
January 31, 1997 have been derived from the unaudited Combined Financial
Statements of the Kilroy Group and, in the opinion of management, include all
adjustments, consisting only of normal recurring adjustments, necessary for a
fair statement of operating information for the unaudited periods. The summary
consolidated historical financial and operating information as of June 30, 1997
and for the five-month period from February 1, 1997 to June 30, 1997 have been
derived from the unaudited Consolidated Financial Statements of the Company
and, in the opinion of management, include all adjustments, consisting only of
normal recurring adjustments, necessary for a fair statement of the operating
information for the unaudited period. For a discussion of the six months ended
June 30, 1997 (adjusted to assume the IPO and the Formation Transactions had
been consummated on January 1, 1997, but not adjusted to reflect consummation
of the acquisitions, of the Acquired and Pending Properties). See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Results of Operations--Adjusted Six Months Ended June 30, 1997 Compared to Six
Months Ended June 30, 1996." The pro forma data assume the consummation of the
Offering and use of the aggregate net proceeds therefrom to purchase the
Acquired and Pending Properties as of the beginning of the periods presented
for the operating data and as of the balance sheet date for the balance sheet
data. The pro forma financial data are not necessarily indicative of what the
actual financial position or results of operations of the Company would have
been as of and for the periods indicated, nor does it purport to represent the
future financial position and results of operations.

(1) Pro forma net income per share equals pro forma net income divided by the
24,475,000 shares of Common Stock outstanding after the Offering.
(2) As defined by the National Association of Real Estate Investment Trusts
("NAREIT"), "Funds from Operations" represents net income (loss) before
minority interest of 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 Funds from Operations were as
follows: in all periods, depreciation and amortization; in 1996, 1995 and
1994, gains on extinguishment of debt; and in pro forma 1997 and 1996 and
in the six months ended June 30, 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 industry
analysts have accepted it as such. 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 such other REITs.
Further, Funds from Operations does not represent amounts available for
management's discretionary use because of needed capital replacement or
expansion, debt service obligations, or other commitments and
uncertainties. See the notes to the historical financial statements of the
Kilroy Group. Funds from Operations should not be considered as an
alternative for net income as a measure of profitability nor is it
comparable to cash flows provided by operating activities determined in
accordance with GAAP.
(3) Funds from Operations and cash flow information is comprised 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 June 30, 1997.

CONFLICTS OF INTEREST

Certain Limited Partner Approval Rights. While Kilroy Realty Corporation is
the sole general partner of the Operating Partnership, and generally has full
and exclusive responsibility and discretion in the management and control of
the Operating Partnership, certain provisions of the Partnership Agreement
place limitations on Kilroy Realty Corporation's ability to act with respect
to the Operating Partnership. The Partnership Agreement provides that if the
limited partners own at least 5% of the outstanding Units (including Units
held by Kilroy Realty Corporation which upon consummation of the Offering will
represent 89.7% of all Units outstanding), Kilroy Realty Corporation shall
not, on behalf of the Operating Partnership, take any of the following actions
without the prior consent of the holders of more than 50% of the limited
partnership Units: (i) dissolve the Operating Partnership, other than incident
to a merger or sale of substantially all of the Company's assets; or
(ii) prior to January 31, 2004, sell the Office Property located at 2260 E.
Imperial Highway at Kilroy Airport Center at El Segundo, other than incident
to a merger or sale of substantially all of the Company's assets. Furthermore,
the Partnership Agreement provides that, except in connection with certain
transactions, Kilroy Realty Corporation may not voluntarily withdraw from the
Operating Partnership, or transfer or assign its interest in the Operating
Partnership, without the consent of the holders of at least 60% of the Units
(including Units held by Kilroy Realty Corporation) and without meeting
certain other criteria with respect to the consideration to be received by the
limited partners. In addition, Kilroy Realty Corporation has agreed to use its
commercially reasonable efforts to structure certain merger transactions to
avoid causing the limited partners to recognize gain for federal income tax
purposes by virtue of the occurrence of or their participation in such
transactions. The restrictions on Kilroy Realty Corporation's ability to act
as described above may result in Kilroy Realty Corporation being precluded
from taking action which the Board of Directors believes is in the best
interest of all stockholders. See "Partnership Agreement of the Operating
Partnership--Transferability of Interests" and "--Certain Limited Partner
Approval Rights."

Tax Consequences Upon Sale or Refinancing. Unlike persons acquiring shares
of Common Stock in the Offering, Unitholders may suffer different and more
adverse tax consequences than the Company upon the sale or refinancing of
certain of the properties owned by the Operating Partnership, and therefore
such holders may have different objectives regarding the appropriate pricing
and timing of any sale or refinancing of such properties. While Kilroy Realty
Corporation, as the sole general partner of the Operating Partnership, has the
authority (subject to certain limited partner approval rights described above)
to determine whether and on what terms to sell or refinance each property
owned solely by the Operating Partnership, those directors and officers of the
Company who hold Units may seek to influence the Company not to sell or
refinance such properties, even though such a sale might otherwise be
financially advantageous to the Company, or may seek to influence the Company
to refinance such properties with a higher level of debt. The Partnership
Agreement provides that if the limited partners own at least 5% of the
outstanding Units (including Units held by the Company which

24
<PAGE>

will represent 89.7% of all Units outstanding), the Company shall not, on
behalf of the Operating Partnership, take any of the following actions without
the prior consent of the holders of more than 50% of the limited partnership
Units: (i) dissolve the Operating Partnership, other than incident to a merger
or sale of substantially all of the Company's assets; or (ii) prior to January
31, 2004, sell the Office Property at 2260 E. Imperial Highway at Kilroy
Airport Center at El Segundo, other than incident to a merger or sale of
substantially all of the Company's assets. The Operating Partnership will also
use commercially reasonable efforts to cooperate with the limited partners to
minimize any taxes payable in connection with any repayment, refinancing,
replacement or restructuring of indebtedness, or any sale, exchange or any
other disposition of assets, of the Operating Partnership. See "Partnership
Agreement of the Operating Partnership--Transferability of Interests" and "--
Certain Limited Partner Approval Rights."

Failure to Enforce Terms of Certain Agreements. As Unitholders, John B.
Kilroy, Sr., as Chairman of the Board of Directors, and John B. Kilroy, Jr.,
as the Company's President and Chief Executive Officer and a director of the
Company, have a conflict of interest with respect to their obligations as
directors or officers of the Company to enforce the terms of the agreements
relating to the Company's option to purchase certain properties owned by
entities controlled by them. See "Business and Properties--Option Properties."
The failure to enforce the material terms of those agreements (which would
require the approval of the Independent Directors) could result in a monetary
loss to the Company, which loss could have a material effect on the Company's
financial condition or results of operations. While certain Unitholders
provide indemnities in connection with such transfers, such indemnities would
be impaired to the extent that such Unitholders have other obligations,
including obligations for taxes arising from prior transactions, which they
may not have sufficient assets to satisfy.

Policies with Respect to Conflicts of Interest. The Company has adopted
certain policies designed to eliminate or minimize conflicts of interest.
These policies include (i) provisions in the Company's articles of
incorporation (the "Articles of Incorporation") and bylaws (the "Bylaws")
which require that at least a majority of the directors be Independent
Directors, (ii) provisions in the Bylaws which require that a majority of the
Independent Directors approve transactions between the Company and certain
Unitholders, including the exercise of the options with respect to the Option
Properties, and the sale or refinancing of the Properties and (iii) the
requirement that the members of the Board of Directors who are Unitholders
(John B. Kilroy, Jr. and John B. Kilroy, Sr.) abide by their respective
noncompetition agreements with the Company. The provisions contained in the
Articles of Incorporation can be modified only with the approval of two-thirds
of the shares of the Company's outstanding and entitled to vote thereon, and
the provisions contained in the Bylaws can be modified only with the approval
of a majority of either the Board of Directors or the shares of the Common
Stock outstanding and entitled to vote thereon. However, there can be no
assurance that these policies will not be changed in the future or that they
otherwise always will be successful in eliminating the influence of such
conflicts, and, if they are not successful, decisions could be made that might
fail to reflect fully the interests of all stockholders. See "Policies with
Respect to Certain Activities--Conflict of Interest Policies."

Competitive Real Estate Activities of Management. John B. Kilroy, Sr. and
John B. Kilroy, Jr. have controlling ownership interests in a complex of three
office buildings which are located in the El Segundo submarket in which four
office buildings and four industrial buildings are located. These properties
and Calabasas Park Centre, an approximately 66-acre undeveloped site
(representing approximately 45 developable acres, net of acreage required for
streets and contractually required open areas) are managed by the Operating
Partnership, and certain of the Company's officers, directors and employees
spend an immaterial portion of their time and effort managing these interests.
The Company is actively marketing the sale of all but 18 acres of Calabasas
Park Centre. Certain of the Company's officers, directors and employees spend
an immaterial amount of time in connection with any sales of such parcels.

Each of these properties is currently owned by partnerships owned and
controlled by John B. Kilroy, Sr. and John B. Kilroy, Jr. The complex of three
office buildings located on North Sepulveda Boulevard in El Segundo is managed
by the Operating Partnership pursuant to a management agreement on market
terms. Calabasas Park Centre is managed by the Services Company pursuant to a
management agreement on market terms. See "Business and Properties--Option
Properties."

25
<PAGE>

Certain partnerships and trusts affiliated with the Company's predecessor,
KI, hold certain other real estate interests which were not contributed to the
Company as part of the Formation Transactions. All of such other real estate
interests relate to miscellaneous properties and property rights that the
Company believes are not of a type appropriate for inclusion in the Company's
portfolio and the properties are not consistent with the Company's strategy.

ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT

Tax Liabilities as a Consequence of Failure to Qualify as a REIT. The
Company intends to operate so as to qualify as a REIT under Sections 856
through 860 of the Internal Revenue Code of 1986, as amended (the "Code"),
commencing with its taxable year ending December 31, 1997. Although management
believes that the Company is organized and operates in such a manner, 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 so qualified.
Qualification as a REIT involves the satisfaction of numerous requirements
established under highly technical and complex Code provisions for which there
are only limited judicial and administrative interpretations, and involves the
determination of various factual matters and circumstances not entirely within
the Company's control. 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 and the Company must pay distributions to stockholders aggregating
annually at least 95% of its REIT taxable income (determined without regard to
the dividends paid deduction and by excluding net capital gains). The
complexity of these provisions and of the applicable Treasury Regulations that
have been promulgated under the Code is greater in the case of a REIT that
holds its assets in partnership form. No assurance can be given that
legislation, new regulations, administrative interpretations or court
decisions will not significantly change the tax laws with respect to
qualification as a REIT or the federal income tax consequences of such
qualification. The Company is relying on the opinion of Latham & Watkins, tax
counsel to the Company, regarding various issues affecting the Company's
ability to qualify, and continue to qualify, as a REIT. See "Federal Income
Tax Consequences--Taxation of the Company" and "Legal Matters." Such legal
opinion is based on various assumptions and factual representations by the
Company regarding the Company's ability to meet the various requirements for
qualification as a REIT, and no assurance can be given that actual operating
results will meet these requirements. Such legal opinion is not binding on the
Internal Revenue Service (the "IRS") or any court.

Among the requirements for REIT qualification is that the value of any one
issuer's securities held by a REIT may not exceed 5% of the REIT's total
assets on certain testing dates. See "Federal Income Tax Consequences--
Taxation of the Company--Requirements for Qualification." The Company believes
that its allocable share of the aggregate value of the securities of the
Services Company held by the Operating Partnership will be less than 5% of the
value of the Company's total assets. In rendering its opinion as to the
qualification of the Company as a REIT, Latham & Watkins relied on the
conclusions of the Company regarding the value of the Services Company.

If the Company were to fail to qualify as a REIT in any taxable year, the
Company would be subject to federal income tax (including any applicable
alternative minimum tax) on its taxable income at regular corporate rates and
would not be allowed a deduction in computing its taxable income for amounts
distributed to its stockholders. Moreover, unless entitled to relief under
certain statutory provisions, the Company also would be disqualified from
treatment as a REIT for the four taxable years following the year during which
qualification is lost. This treatment would reduce the net earnings of the
Company available for investment or distribution to stockholders because of
the additional tax liability to the Company for the years involved. In
addition, distributions to stockholders would no longer be required to be
made. See "Federal Income Tax Consequences--Taxation of the Company--
Requirements for Qualification."

Other Tax Liabilities. Even if the Company qualifies for and maintains its
REIT status, it is subject to certain federal, state and local taxes on its
income and property. For example, if the Company has net income from a
prohibited transaction, such income will be subject to a 100% tax. In
addition, net income, if any, from the third-party development conducted
through the Services Company is subject to federal income tax at regular
corporate tax rates. See "Federal Income Tax Consequences--Services Company."

26
<PAGE>

RISKS OF DEVELOPMENT BUSINESS AND RELATED ACTIVITIES BEING CONDUCTED BY THE
SERVICES COMPANY

Tax Liabilities. The Services Company is subject to federal and state income
tax on its taxable income at regular corporate rates. Any federal, state or
local income taxes that the Services Company is required to pay will reduce
the cash available for distribution by the Services Company to the Operating
Partnership.

Adverse Consequences of Lack of Control Over the Businesses of the Services
Company. To comply with the REIT asset tests that restrict ownership of shares
of other corporations, the Operating Partnership owns 100.0% of the nonvoting
preferred stock of the Services Company (representing approximately 95.0% of
its economic value) and John B. Kilroy, Sr. and John B. Kilroy, Jr. own all
the outstanding voting common stock of the Services Company (representing
approximately 5.0% of its economic value). This ownership structure is
necessary to permit the Company to share in the income of the Services Company
and also maintain its status as a REIT. Although the Company receives
substantially all of the economic benefit of the businesses carried on by the
Services Company through the Company's right to receive dividends through the
Operating Partnership, the Company is not able to elect directors or officers
of the Services Company and, therefore, the Company does not have the ability
to influence the operations of the Services Company or require that the
Services Company's board of directors declare and pay a cash dividend on the
nonvoting preferred stock of the Services Company held by the Operating
Partnership. As a result, the board of directors and management of the
Services Company may implement business policies or decisions that would not
have been implemented by persons controlled by the Company and that are
adverse to the interests of the Company or that lead to adverse financial
results, which could adversely impact the Company's net operating income and
cash flow. See "Formation and Structure of the Company."

Adverse Consequence of REIT Status on the Businesses of the Services
Company. Certain requirements for REIT qualification may in the future limit
the Company's ability to receive increased distributions from the fee
development operations conducted and related services offered by the Services
Company. See "--Adverse Consequences of Failure to Qualify as a REIT."

CASH FLOW FROM DEVELOPMENT ACTIVITIES IS UNCERTAIN. A portion of the
Company's anticipated cash flow is generated from development activities which
are partially dependent on the availability of development opportunities and
which are subject to the risks inherent with development and general economic
conditions. In addition, development activities are subject to limitations
imposed by the REIT tests. See "Federal Income Tax Consequences--Taxation of
the Company--Income Tests." There can be no assurance that the Company will
realize completely such anticipated cash flows. See "Risk Factors--Real Estate
Investment Considerations--Risks of Real Estate Acquisition and Development."
Also, these development activities generally are conducted by the Services
Company. Accordingly, cash flow from these activities is further dependent
upon the decision of the Services Company's board of directors to declare and
pay a cash dividend on the nonvoting preferred stock held by the Operating
Partnership. See "--Risks of Development Business and Related Activities Being
Conducted by the Services Company."

DEPENDENCE ON SOUTHERN CALIFORNIA MARKET. The Company's portfolio is
comprised of 85 buildings (including the Pending Acquisitions), 77 of which
are located in Southern California and encompass an aggregate of approximately
5.5 million rentable square feet (representing approximately 84.2% of the
aggregate rentable square feet of all of the Properties). Consequently, the
Company's performance is linked to economic conditions and the demand for
office and industrial space in this region. The Southern California economy
has experienced significant recessionary conditions in the past several years,
primarily as a result of the downsizing of the aerospace and defense
industries; there is still a dependence on these industries in the Company's
El Segundo and Long Beach Airport area submarkets. The recessionary conditions
resulted in a general increase in vacancies and a general decrease in net
absorption and rental rates in the Company's El Segundo and Long Beach Airport
area submarkets. Although the recently announced disposition of defense and
satellite services businesses of Hughes Electronics Corporation does not
involve tenants at the Properties, any resulting vacancy in the Company's
submarkets may have an adverse effect on rental rates and occupancy at the
Properties. Any decline in the Southern California economy generally may
result in a material decline in the demand for office and

27
<PAGE>

industrial space, may have a material adverse effect greater than if the
Company had a more geographically diverse portfolio of properties, and may
materially and adversely affect the ability of the Company to make
distributions to stockholders.

In addition, eight office buildings, representing approximately 45.4% of the
aggregate office space of all of the Office Properties as of June 30, 1997,
are located in two office parks in El Segundo, California, and Long Beach,
California, respectively.

DEPENDENCE ON SIGNIFICANT TENANTS. The Company's 20 largest tenants
represented approximately 54.0% of total base rent revenues for the year ended
December 31, 1996. Of this amount, its largest tenant, Hughes Space &
Communications, currently leases approximately 530,000 rentable square feet of
office space in Kilroy Airport Center at El Segundo, representing
approximately 15.9% of the Company's total rent for the year ended December
31, 1996, giving pro forma effect to (i) the acquisition of the Acquired and
Pending Properties and (ii) the Boeing Lease. The base periods of the Hughes
Space & Communications leases expire beginning in January 1999. The Company's
revenues and cash available for distribution to stockholders would be
disproportionately and materially adversely affected in the event of
bankruptcy or insolvency of, or a downturn in the business of, or the
nonrenewal of leases by, any of its significant tenants, or the renewal of
such leases on terms less favorable to the Company than their current terms.

DISTRIBUTIONS TO STOCKHOLDERS AFFECTED BY MANY FACTORS. Distributions by the
Company to its stockholders are based principally on cash available for
distribution from the Properties. Contractual increases in base rent under
existing leases, reductions in mortgage indebtedness or decreases in
applicable interest rates each could have the effect of increasing cash
available for distribution. Similarly, and by way of example, increases in
interest rates, the issuance of Common Stock or Units in connection with the
acquisition of properties with cash flow levels lower than that for the
Properties and the use of internally generated cash to fund, in whole or in
part, any development activities or property acquisitions, each could have the
effect of decreasing cash available for distribution. However, in the event of
a default or a lease termination by a lessee, there could be a decrease or
cessation of rental payments and thereby a decrease in cash available for
distribution. In addition, the amount available to make distributions may
decrease if properties acquired in the future yield lower than expected
returns.

The distribution requirements for REITs under federal income tax laws may
limit the Company's ability to finance future developments, acquisitions and
expansions without additional debt or equity financing. If the Company incurs
additional indebtedness in the future, it will require additional funds to
service such indebtedness and as a result amounts available to make
distributions may decrease. Distributions by the Company are also dependent on
a number of other factors, including the Company's financial condition, any
decision to reinvest funds rather than to distribute such funds, capital
expenditures, the annual distribution requirements under the REIT provisions
of the Code and such other factors as the Company deems relevant. In addition,
the Company may issue from time to time additional Units or shares of Common
Stock in connection with the acquisition of properties or in certain other
circumstances. No prediction can be made as to the number of such Units or
shares of Common Stock which may be issued, if any, and, if issued, the effect
on cash available for distribution on a per share basis to holders of Common
Stock. Such issuances, if any, may have a dilutive effect on cash available
for distribution on a per share basis to holders of Common Stock. See "The
Company--Growth Strategies." The possibility exists that actual results of the
Company may differ from the assumptions used by the Board of Directors in
determining the initial distribution rate.

To obtain the favorable tax treatment associated with REITs, the Company
generally is required to distribute to its stockholders at least 95% of its
taxable income (determined without regard to the dividends paid deduction and
by excluding net capital gains) each year. In addition, the Company is subject
to tax at regular corporate rates to the extent that it distributes less than
100% of its taxable income (including net capital gains) each year. The
Company is also subject to a 4% nondeductible excise tax on the amount, if
any, by which certain distributions paid by it with respect to 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.

28
<PAGE>

The Company intends to continue to make distributions to its stockholders to
comply with the distribution requirements of the Code and to reduce exposure
to federal income taxes and the nondeductible excise tax. Differences in
timing between the receipt of income and the payment of expenses in arriving
at taxable income and the effect of required debt amortization payments could
require the Company to borrow funds on a short-term basis to meet the
distribution requirements that are necessary to achieve the tax benefits
associated with qualifying as a REIT.

REAL ESTATE INVESTMENT CONSIDERATIONS

General. Real property investments are subject to varying degrees of risk.
The yields available from equity investments in real estate depend on the
amount of income earned and capital appreciation generated by the related
properties as well as the expenses incurred in connection therewith. If the
Properties do not generate income sufficient to meet operating expenses,
including debt service and capital expenditures, the ability to make
distributions to the Company's stockholders could be adversely affected.
Income from, and the value of, the Properties may be adversely affected by the
general economic climate, local conditions such as oversupply of office,
industrial or retail space or a reduction in demand for office, industrial or
retail space in the area, the attractiveness of the Properties to potential
tenants, competition from other office, industrial and retail buildings, and
the ability of the Company to provide adequate maintenance and insurance and
increased operating costs (including insurance premiums, utilities and real
estate taxes). In addition, revenues from properties and real estate values
are also affected by such factors as the cost of compliance with regulations
and the potential for liability under applicable laws, including changes in
tax laws, interest rate levels and the availability of financing. The
Company's income would be adversely affected if a significant number of
tenants were unable to pay rent or if office or industrial space could not be
rented on favorable terms. Certain significant expenditures associated with an
investment in real estate (such as mortgage payments, real estate taxes and
maintenance costs) generally are not reduced when circumstances cause a
reduction in income from the investment.

Illiquidity of Real Estate. Real estate investments are relatively illiquid
and, therefore, the Company has a limited ability to vary its portfolio
quickly in response to changes in economic or other conditions. In addition,
the prohibition in the Code and related regulations on a REIT holding property
for sale may affect the Company's ability to sell properties without adversely
affecting distributions to the Company's stockholders.

Competition. The Company plans to continue to expand, primarily through the
acquisition and development of additional office and industrial buildings in
Southern California and other markets where the acquisition and/or development
of property would, in the opinion of management, result in a favorable risk-
adjusted return on investment. There are a number of office and industrial
building developers and real estate companies that compete with the Company in
seeking properties for acquisition, prospective tenants and land for
development. Substantially all of the Properties are in developed areas where
there are generally other properties of the same type. Competition from other
office and industrial properties may affect the Company's ability to attract
and retain tenants, rental rates and expenses of operation (particularly in
light of the higher vacancy rates of many competing properties which may
result in lower-priced space being available in such properties). The Company
may be competing with other entities that have greater financial and other
resources than the Company. During the period beginning January 1, 1994 and
ending June 30, 1997, the weighted average renewal rate, based on rentable
square footage, was 74.1% for the Properties owned by the Company upon
consummation of the IPO located in the Southern California Area and 63.5% for
the Properties overall. The lower overall retention rate is due primarily to
the termination in 1993 of a lease with Boeing, scheduled to expire in 1995,
for approximately 211,000 rentable square feet at the SeaTac Office Center.
This office space was released by Boeing on June 20, 1997 with occupancy
schedule to commence not later than December 31, 1997. See "Business and
Properties--Office Properties--Kilroy Airport Center, SeaTac."

Lease Expirations. Certain leases expiring during the first several years
following the Offering are at rental rates higher than those attained by the
Company in its recent leasing activity. Such leases, or other leases of the
Company, may not be renewed or, if renewed, may be renewed at rental rates
lower than rental rates in effect immediately prior to expiration. Decreases
in the rental rates for the Company's properties, the failure of tenants to
renew any such leases or the failure of the Company to re-lease any of the
Company's space could materially

29
<PAGE>

adversely affect the Company and its ability to make distributions. During the
three calendar years ending December 31, 1999, the Company will have expiring
leases for its Office Properties covering approximately 767,000 rentable
square feet, and expiring leases for Industrial Properties covering
approximately 1.1 million rentable square feet. For the year ended December
31, 1996, the expiring leases for the Office Properties and the Industrial
Properties had a weighted average annual base rent per rentable square foot of
approximately $16.86 and $5.54, respectively. For the 12-month period ending
December 31, 1996, the Company entered into 47 Office Property lease
transactions for approximately 491,000 rentable square feet with an annual
base rent per rentable square foot of $18.62. For the 12-month period ending
December 31, 1996, the Company entered into one Industrial Property lease
transaction for approximately 62,500 rentable square feet with an annual base
rent per rentable square foot of $6.36. For the six-month period ended June
30, 1997, the Company entered into six office property lease transactions for
an aggregate of approximately 33,000 rentable square feet with a weighted
average annual base rent per rentable square foot of approximately $15.70. Of
this amount, approximately 27,000 rentable square feet was leased to one
tenant at the SeaTac Office Center at an average rent per square foot of
approximately $13.88. The remaining approximately 6,000 rentable square feet
was leased at various properties at an average rent per square foot of $24.80.
For the six-month period ended June 30, 1997, the Company entered into one
industrial property lease transaction for 4,600 rentable square feet with an
annual base rent per rentable square foot of $7.33. See "Business and
Properties--General" and "--Lease Expirations."

Ground Leases. The eight office buildings located at Kilroy Airport Center
in Long Beach and the SeaTac Office Center are held subject to ground leases.
A default by the Company under the terms of a ground lease could result in the
loss of such Properties located on the respective parcel, unless the default
under the lease is cured or waived. In addition, upon expiration of the ground
leases, including the options thereon, there is no assurance that the Company
will be able to negotiate new ground leases at all or, if any leases were
renewed, that they will be on terms consistent with or more favorable than
existing terms, which may result in the loss of such Properties or increased
rental expense to the Company. The ground leases for the Kilroy Airport Center
Long Beach will expire in 2035. See "Business and Properties--Office
Properties--Kilroy Airport Center, Long Beach." The ground leases for the
SeaTac Office Center (including renewal options) will expire in 2062. See
"Business and Properties--Office Properties--Kilroy Airport Center, SeaTac."

Capital Improvements. The Properties vary in age and require capital
improvements regularly. If the cost of improvements, whether required to
attract and retain tenants or to comply with governmental requirements,
substantially exceeds management's expectations, cash available for
distribution could be reduced.

Risks of Real Estate Acquisition and Development. The Company intends to
continue to actively seek to acquire office and industrial properties to the
extent that they can be acquired on advantageous terms and meet the Company's
investment criteria. Acquisitions of office and industrial properties entail
risks that investments will fail to perform in accordance with expectations.
Estimates of the costs of improvements to bring an acquired property up to
standards established for the market position intended for that property may
prove inaccurate. In addition, there are general investment risks associated
with any new real estate investment. If the Company enters into the
transactions contemplated by the Allen LOI, it will have substantial financial
commitments with respect thereto. See "--Real Estate Financing Risks" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources."

In addition to the Development Properties, the Company will continue to
pursue other development opportunities both for ownership by the Company and
on a fee basis. The real estate development business involves significant
risks in addition to those involved in the ownership and operation of
established office or industrial buildings, including the risks that financing
may not be available on favorable terms for development projects and
construction may not be completed on schedule or within budget, resulting in
increased debt service expense and construction costs and delays in leasing
such properties and generating cash flow. In addition, new development
activities, regardless of whether or not they are ultimately successful,
typically require a substantial portion of management's time and attention.
Development activities are also subject to risks relating to the inability to
obtain, or delays in obtaining, all necessary zoning, land-use, building,
occupancy, and other required governmental permits and authorizations.

30
<PAGE>

The Company anticipates that additional future acquisitions and developments
will be financed, in whole or in part, through additional equity offerings,
lines of credit and other forms of secured or unsecured financing. If new
developments are financed through construction loans, there is a risk that,
upon completion of construction, permanent financing for newly developed
properties may not be available or may be available only on disadvantageous
terms. Equity, rather than debt, financing of future acquisitions or
developments may have a dilutive effect on the interests of existing
stockholders of the Company.

While the Company has focused primarily on the development and ownership of
office and industrial properties, the Company may in the future develop
properties, part or all of which will be for retail use. In addition, while
the Company has historically limited its ownership of properties primarily to
the Southern California market, the Company in the future may expand its
business to geographic markets other than Southern California, where the
acquisition and/or development of property would, in the opinion of
management, result in a favorable risk-adjusted return on investment. The
Company does not possess the same level of familiarity with retail development
or markets outside of those in which the Properties presently are located,
which could adversely affect its ability to acquire or develop properties in
any new localities or to realize expected performance.

Uninsured Losses. Management believes that the Properties are covered by
adequate comprehensive liability, rental loss and all-risk insurance provided
by reputable companies and with commercially reasonable deductibles, limits
and policy specifications customarily carried for similar properties. Certain
types of losses, however, may be either uninsurable or not economically
insurable, such as losses due to floods, riots or acts of war, or may be
insured subject to certain limitations including large deductibles or co-
payments, such as losses due to seismic activity. See discussion of uninsured
losses from seismic activity below. Should an uninsured loss or a loss in
excess of insured limits occur, the Company could lose its investment in and
anticipated profits and cash flow from a property and would continue to be
obligated on any mortgage indebtedness or other obligations related to such
property. Any such loss would adversely affect the Company and its ability to
make distributions.

Uninsured Losses from Seismic Activity. The Properties are located in areas
that are subject to earthquake activity including concentrations of Properties
located in southwest Los Angeles County which represented approximately 46.7%
of the Company's aggregate base rent for the year ended December 31, 1996,
giving pro forma effect for the acquisition of the Acquired and Pending
Properties. Although the Company has earthquake insurance on a substantial
portion of its Properties, such insurance is not replacement cost and should
any Property sustain damage as a result of an earthquake, or should losses
exceed the amount of such coverage, the Company would incur uninsured losses
or losses due to deductibles or co-payments on insured losses. See "Business
and Properties--Uninsured Losses from Seismic Activity."

Risks of Tenant Bankruptcy. At any time, tenants of the Properties may
become unable to pay their rent or meet their obligations to the Company,
otherwise default under their leases or become debtors in cases under the
Bankruptcy Code. If any tenant becomes a debtor in a case under the Bankruptcy
Code, the Company would not be permitted to evict the tenant solely because of
its bankruptcy, but the bankruptcy court could authorize the tenant to reject
and terminate its lease with the Company. The Company's claim against such a
tenant for unpaid, future rent would be subject to a statutory cap that could
be substantially less than the remaining rent actually owned under the lease.
In any event, the Company's claim for unpaid rent (as capped) would likely not
be paid in full, which 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, no assurance can be
given that tenants will not file for bankruptcy protection in the future or,
if any tenants file, that they will affirm their leases and continue to make
rental payments in a timely manner.

Risks Involved in Property Ownership Through Partnerships and Joint
Ventures. Although the Company owns fee simple interests in the Properties
(other than Kilroy Airport Center Long Beach and the SeaTac Office Center,
which are held subject to long-term ground leases), in the future the Company
may also participate with other entities in property ownership through joint
ventures or partnerships. Partnership or joint venture investments may, under
certain circumstances, involve risks not otherwise present, including the
possibility that the Company's partners or co-venturers might become bankrupt
which could result in the Company becoming responsible for the liabilities of
the joint venture or partnership, that such partners or co-venturers might at
any time have economic or other business interests or goals which are

of the Company, and that such partners or co-venturers may be in a position to
take action contrary to the instructions or the requests of the Company or
contrary to the Company's policies or objectives, including the Company's
policy with respect to maintaining its qualification as a REIT. The Company,
however, will seek to maintain sufficient control of such partnerships or
joint ventures to permit the Company's business objectives to be achieved.
There is no limitation under the Company's organizational documents as to the
amount of available funds that may be invested in partnerships or joint
ventures.

REAL ESTATE FINANCING RISKS. The Company is subject to the risks normally
associated with debt financing, including the risk that the Company's cash
flow will be insufficient to meet required payments of principal and interest,
the risk that indebtedness on the Properties will not be refinanced at
maturity or that the terms of such refinancing will not be as favorable as the
terms of such indebtedness. If the Company were unable to refinance its
indebtedness on acceptable terms, or at all, the Company might be forced to
dispose of one or more of the Properties upon disadvantageous terms, which
might result in losses to the Company and might adversely affect the cash
available for distribution. If prevailing interest rates or other factors at
the time of refinancing result in higher interest rates on refinancings, the
Company's interest expense would increase, which would adversely affect the
Company's cash flow and its ability to pay expected distributions to
stockholders. Further, if a Property is mortgaged to secure payment of
indebtedness and the Company is unable to meet mortgage payments, or is in
default under the related mortgage or deed of trust, such Property could be
transferred to the mortgagee, the mortgagee could foreclose upon the Property,
appoint a receiver and receive an assignment of rents and leases or pursue
other remedies, all with a consequent loss of income and asset value to the
Company. The Credit Facility and the Mortgage Loans each are secured by
portions of the Property portfolio. Consequently, a default by the Company
related to the Credit Facility or either of the Mortgage Loans could result in
foreclosure on the Properties securing such loan. In addition, because the
Credit Facilities and the Mortgage Loans contain cross default provisions, a
default related to either the Credit Facility or either of the Mortgage Loans
could result in a default of such other indebtedness. Foreclosures could also
create taxable income without accompanying cash proceeds, thereby hindering
the Company's ability to meet the REIT distribution requirements of the Code.
See "Description of Indebtedness."

CHANGES IN INVESTMENT AND FINANCING POLICIES WITHOUT STOCKHOLDER
VOTE. Subject to the Company's fundamental investment policy to maintain its
qualification as a REIT (unless a change is approved by the Board of Directors
and stockholders), the Board of Directors determines its investment and
financing policies, its growth strategy, and its debt, capitalization,
distribution and operating policies. Although the Board of Directors has no
present intention to revise or amend these strategies and policies, the Board
of Directors may do so at any time without a vote of the Company's
stockholders. See "Policies With Respect to Certain Activities--Other
Policies." Accordingly, stockholders will have no control over changes in
strategies and policies of the Company, and such changes may not serve the
interests of all stockholders and could adversely affect the Company's
financial condition or results of operations, including its ability to
distribute cash to stockholders.

Issuance of Additional Securities. The Company has authority to offer its
Common Stock or other equity or debt securities in exchange for property or
otherwise. Similarly, the Company may cause the Operating Partnership to offer
additional Units or preferred units of the Operating Partnership, including
offers in exchange for property to sellers who seek to defer certain of the
tax consequences relating to a property transfer. Such issuances could dilute
the ownership interest of the Company in the Operating Partnership. Existing
stockholders have no preemptive rights to acquire any such securities, and any
such issuance of equity securities could result in dilution in an existing
stockholder's investment in the Company.

Risks Involved in Investments in Securities Related to Real Estate. The
Company may pursue its investment objectives through the ownership of
securities of entities engaged in the ownership of real estate. Ownership of
such 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 ability to control the distributions with respect to such
securities, which may adversely affect the Company's ability to make required
distributions to stockholders. Furthermore, if the Company desires to control
an issuer of securities, it may be prevented from doing so by the limitations
on percentage ownership and gross income tests which must be satisfied by the

32
<PAGE>

Company in order for the Company to qualify as a REIT. See "Federal Income Tax
Consequences--Taxation of the Company--Requirements for Qualification as a
REIT." The Company operates its business in a manner that does not require the
Company to register under the Investment Company Act of 1940 and stockholders
do therefore not have the protection of that act.

The Company may also invest in mortgages and may do so as a strategy for
ultimately acquiring the underlying property. In general, investments in
mortgages include the risk that borrowers may not be able to make debt service
payments or pay principal when due, the risk that the value of the mortgaged
property may be less than the principal amount of the mortgage note securing
such property and the risk that interest rates payable on the mortgages may be
lower than the Company's cost of funds to acquire these mortgages. In any of
these events, Funds from Operations and the Company's ability to make required
distributions to stockholders could be adversely affected.

RISK OF OPERATIONS CONDUCTED THROUGH THE OPERATING PARTNERSHIP. The Company,
through its subsidiaries, will own upon consummation of the Offering an
approximately 89.7% economic interest in the Properties. The remaining
interests in the Operating Partnership are owned by the remaining Unitholders.
Although the number of limited partnership Units is designed to result in a
distribution per Unit equal to a distribution per share of Common Stock, such
distributions are equal only if the Company distributes to stockholders all
amounts it receives in distributions from the Operating Partnership. See
"Formation and Structure of the Company--Formation Transactions." In addition,
under the terms of the Partnership Agreement, the limited partners of the
Operating Partnership have certain approval rights with respect to certain
transactions that affect all stockholders. See "--Conflicts of Interest--
Certain Limited Partner Approval Rights."

INFLUENCE OF CERTAIN UNITHOLDERS. John B. Kilroy, Sr., the Chairman of the
Board of Directors, and John B. Kilroy, Jr., the Company's President and Chief
Executive Officer and one of its directors, will own, together with the other
limited partner Unitholders, Units exchangeable for shares of Common Stock
equal to approximately 10.3% of the total outstanding shares, after giving
effect to the Offering (and, together with options exercisable for shares of
Common Stock, 11.2% of the total outstanding shares, after giving effect to
the Offering). In addition, the Messrs. Kilroy hold two of the Company's five
seats on the Board of Directors. Under the terms of the Company's charter, no
other stockholder presently is permitted to own, actually or constructively,
in excess of 7.0% of the Common Stock. In addition, although the Messrs.
Kilroy will not be able to take action on behalf of the Company without the
concurrence of other members of the Board of Directors, they will, for so long
as limited partners of the Operating Partnership own at least 5% of the
outstanding Units, be able to block, absent the prior consent of at least a
majority of the limited partners, (i) the dissolution of the Operating
Partnership, or (ii) prior to January 31, 2004, the sale of the Office
Property located at 2260 E. Imperial Highway at Kilroy Airport Center at El
Segundo, in each case other than incident to a merger or sale of all or
substantially all of the Company's assets, and be able to exert substantial
influence over the Company's affairs.

LIMITS ON OWNERSHIP AND CHANGE IN CONTROL. Certain provisions of the
Maryland General Corporation Law (the "MGCL") and the Articles of
Incorporation and Bylaws, and certain provisions of the Partnership Agreement,
could have the effect of delaying, deferring or preventing a change in control
of the Company or the removal of existing management and, as a result, could
prevent the stockholders of the Company from being paid a premium for their
shares of Common Stock over then prevailing market prices.

Limits on Ownership of Common Stock. In order for the Company to maintain
its qualification as a REIT, not more than 50% in value of the outstanding
shares of its capital stock may be owned, actually or constructively, by five
or fewer individuals (as defined in the Code to include certain entities)
during the last half of a taxable year (other than the first year for which
the election to be treated as a REIT has been made). Furthermore, after the
first taxable year for which a REIT election is made, the Company's shares of
Common Stock 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 tax year). In
addition, if the Company, or an owner of 10% or more of the Company, actually
or constructively, owns 10% or more of a tenant of the Company (or a tenant of
any partnership in which the Company is a partner), the rent received by the
Company (either directly or through any such

33
<PAGE>

partnership) from such tenant will not be qualifying income for purposes of
the REIT gross income tests of the Code. See "Federal Income Tax
Consequences--Taxation of the Company." In order to protect the Company
against the risk of losing REIT status due to a concentration of ownership
among its stockholders, the Articles of Incorporation limit actual or
constructive ownership of the outstanding shares of Common Stock by any single
stockholder to 7.0% (the "Ownership Limit") of the then outstanding shares of
Common Stock. See "Description of Capital Stock--Restrictions on Ownership and
Transfer." The Board of Directors will consider waiving the Ownership Limit
with respect to a particular stockholder if it is satisfied, based upon the
advice of tax counsel or otherwise, that ownership by such stockholder in
excess of the Ownership Limit would not jeopardize the Company's status as a
REIT and the Board of Directors otherwise decided such action would be in the
best interests of the Company. The Board of Directors has waived the Ownership
Limit with respect to John B. Kilroy, Sr., John B. Kilroy, Jr., members of
their families and certain affiliated entities and has permitted such
individuals and entities to actually or constructively own, in the aggregate,
up to 19.6% of the outstanding Common Stock.

Actual or constructive ownership of shares of Common Stock in excess of the
Ownership Limit, or, with the consent of the Board of Directors, such other
limit, will cause the violative transfer or ownership to be void with respect
to the transferee or owner as to that number of shares in excess of the
Ownership Limit, or, with the consent of the Board of Directors, such other
limit, as applicable, and such shares will be automatically transferred to a
trust for the benefit of a qualified charitable organization. Such purported
transferee or owner shall have no right to vote such shares or be entitled to
dividends or other distributions with respect to such shares. See "Description
of Capital Stock--Restrictions on Ownership and Transfer" for additional
information regarding the Ownership Limit.

Staggered Board. The Board of Directors is divided into three classes
serving staggered three-year terms. The terms of the first, second and third
classes expire in 1998, 1999 and 2000, respectively. Directors for each class
will be chosen for a three-year term upon expiration of the term, beginning in
1998. In addition, the Articles of Incorporation authorize the Board of
Directors to issue up to 150,000,000 shares of Common Stock and 30,000,000
shares of preferred stock and to establish the rights and preferences of any
shares of preferred stock issued. No shares of preferred stock are currently
issued or outstanding. See "Description of Capital Stock--Preferred Stock."
Under the Articles of Incorporation, stockholders do not have cumulative
voting rights.

The Ownership Limit, the staggered terms for directors, the issuance of
additional common or preferred stock in the future and the absence of
cumulative voting rights could have the effect of (i) delaying or preventing a
change of control of the Company even if a change of control were in the
stockholders' interest, (ii) deterring tender offers for the Common Stock that
may be beneficial to the stockholders, or (iii) limiting the opportunity for
stockholders to receive a premium for their Common Stock that might otherwise
exist if an investor attempted to assemble a block of shares of Common Stock
in excess of the Ownership Limit or otherwise to effect a change of control of
the Company. See "Management" and "Description of Capital Stock."

DEPENDENCE ON KEY PERSONNEL. The Company is dependent on the efforts of its
executive officers and directors, particularly John B. Kilroy, Sr., the
Chairman of the Board of Directors, and John B. Kilroy, Jr., the Company's
President and Chief Executive Officer, for strategic business direction and
experience in the Southern California real estate market. While the Company
believes that it could find replacements for these key personnel, the loss of
their services could have an adverse effect on the operations of the Company.
Since January 31, 1997, the Company has entered into employment agreements
with John B. Kilroy, Jr., President and Chief Executive Officer, Jeffrey C.
Hawken, Executive Vice President and Chief Operating Officer, Richard E. Moran
Jr., Executive Vice President, Chief Financial Officer and Secretary, Campbell
Hugh Greenup, General Counsel, and Tyler H. Rose, Senior Vice President and
Treasurer. See "Management--Employment Agreements."

DISTRIBUTION PAYOUT PERCENTAGE. The Company paid distributions per share of
Common Stock of $0.2583 for the two months ended March 31, 1997, and $0.3875
for the second quarter of 1997. A failure to make expected distributions could
result in a decrease in the market price of the Common Stock. See "Price Range
of Common Stock and Distribution History."

HISTORICAL OPERATING LOSSES OF THE EXISTING OFFICE AND INDUSTRIAL
PROPERTIES. Although the Office and Industrial Properties developed by the
Company after their construction and initial lease-up periods have
historically generated positive net cash flow, the effect of depreciation,
amortization and other non-cash charges has resulted in losses before equity
in income of subsidiary, minority interest and extraordinary item for
financial reporting purposes in each of the last five fiscal years. Historical
operating results of the Office and Industrial Properties that were owned by
the Company upon consummation of the IPO may not be comparable to future
operating results of the Company because, prior to the completion of the IPO
and the Formation Transactions on January 31, 1997, the Office and Industrial
Properties that were owned by the Company upon consummation of the IPO were
encumbered with greater levels of debt (which has the effect of reducing net
income) than that with which the Company currently operates. In addition, the
historical results of operations do not reflect the acquisition and
development of any of the Acquired and Pending Properties. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations." No
assurance can be given that any of the Properties will have profitable results
from operations and will not experience losses in the future.

NO LIMITATION ON DEBT. The Board of Directors currently funds acquisition
opportunities and development partially through short-term borrowings, as well
as out of undistributed cash available for distribution and other available
cash. The Board of Directors expects to refinance projects purchased or
developed with short-term debt either with long-term indebtedness or equity
financing depending upon the economic conditions at the time of refinancing.
The total debt constituted, as of June 30, 1997, approximately 29.9% (and
12.1% as of July 31, 1997 after giving pro forma effect to the Offering and
the application of the estimated net proceeds therefrom) of the total market
capitalization of the Company. The Board of Directors has adopted a policy of
limiting its indebtedness to approximately 50% of its total market
capitalization (i.e., the market value of the issued and outstanding shares of
Common Stock, including interests exchangeable therefor, plus total debt), but
the organizational documents of the Company do not contain any limitation on
the amount or percentage of indebtedness, funded or otherwise, that the
Company may incur. The Board of Directors, without the vote of the Company's
stockholders, could alter or eliminate its current policy on borrowing at any
time at its discretion. If this policy were changed, the Company could become
more highly leveraged, resulting in an increase in debt service that could
adversely affect the Company's cash flow and its ability to make expected
distributions to its stockholders and an increased risk of default on the
Company's obligations. See "Policies With Respect to Certain Activities--
Financing."

The Company has established its debt policy relative to the market
capitalization of the Company rather than to the book value of its assets, a
ratio that is frequently employed. The Company has used total market
capitalization because it believes that the book value of its assets (which to
a large extent is the depreciated value of real property, the Company's
primary tangible asset) does not accurately reflect its ability to borrow and
to meet debt service requirements. The total market capitalization of the
Company, however, is more variable than book value, and does not necessarily
reflect the fair market value of the underlying assets of the Company at all
times. Although the Company will consider factors other than total market
capitalization in making decisions regarding the incurrence of indebtedness
(such as the acquisition cost of properties to be acquired with debt
financing, the estimated market value of such properties upon refinancing and
the ability of particular properties and the Company as a whole to generate
cash flow to cover expected debt service), there can be no assurance that the
ratio of indebtedness to total market capitalization (or to any other measure
of asset value) will be consistent with the expected level of distributions to
the Company's stockholders.

GOVERNMENT REGULATIONS. Many laws and governmental regulations are
applicable to the Properties and changes in these laws and regulations, or
their interpretation by agencies and the courts, occur frequently.

Costs of Compliance with Americans with Disabilities Act. Under the
Americans with Disabilities Act of 1990 (the "ADA"), all places of public
accommodation are required to meet certain federal requirements related to
access and use by disabled persons. Compliance with the ADA might require
removal of structural barriers to handicapped access in certain public areas
where such removal is "readily achievable." Noncompliance with the ADA could
result in the imposition of fines or an award of damages to private litigants.
The impact of application of the ADA to the Properties, including the extent
and timing of required renovations, is uncertain. If

35
<PAGE>

required changes involve a greater amount of expenditures than the Company
currently anticipates or if the changes must be made on a more accelerated
schedule than the Company currently anticipates, the Company's ability to make
expected distributions to stockholders could be adversely affected.

Environmental Matters. Under various federal, state and local laws,
ordinances and regulations relating to the protection of the environment, an
owner or operator of real estate may be held liable for the costs of removal
or remediation of certain hazardous or toxic substances located on or in the
property. These laws often impose liability without regard to whether the
owner was responsible for, or even knew of, the presence of such hazardous or
toxic substances. The costs of investigation, removal or remediation of such
substances may be substantial, and the presence of such substances may
adversely affect the owner's ability to rent or sell the property or to borrow
using such property as collateral and may expose it to liability resulting
from any release of or exposure to such substances. Persons who arrange for
the disposal or treatment of hazardous or toxic substances at another location
may also be liable for the costs of removal or remediation of such substances
at the disposal or treatment facility, whether or not such facility is owned
or operated by such person. Certain environmental laws impose liability for
release of asbestos-containing materials into the air, and third parties may
also seek recovery from owners or operators of real properties for personal
injury associated with asbestos-containing materials and other hazardous or
toxic substances. In connection with the ownership (direct or indirect),
operation, management and development of real properties, the Company may be
considered an owner or operator of such properties or as having arranged for
the disposal or treatment of hazardous or toxic substances and, therefore,
potentially liable for removal or remediation costs, as well as certain other
related costs, including governmental penalties and injuries to persons and
property.

Certain of the Company's tenants routinely handle hazardous substances and
wastes as part of their operations on the Company's properties. Such tenants
are subject to environmental laws and regulations governing the use, storage,
handling and disposal of such materials and such laws and regulations also
could subject the Company to liability resulting from such activities. The
Company's leases generally provide that the tenant must comply with such laws
and regulations and indemnify the Company for any related liabilities. As a
result, the Company does not believe that such matters will have a material
adverse effect on its operations. The Company has not been notified by any
governmental authority, and is not otherwise aware, of any material
noncompliance, liability or claim relating to hazardous or toxic substances or
petroleum products in connection with any of its Properties.

All of the Properties have been subject to Phase I or similar environmental
assessments by independent environmental consultants. Phase I assessments are
intended to discover information regarding, and to evaluate the environmental
condition of, the surveyed property and surrounding properties. Phase I
assessments generally include an historical review, a public records review,
an investigation of the surveyed site and surrounding properties, and
preparation and issuance of a written report, but do not include soil sampling
or subsurface investigations. Such reports have revealed that historical
operations at or in the vicinity of certain of the Existing and Acquired
Properties, including the operation of underground storage tanks, may have
caused soil or groundwater contamination on such properties. For example, with
respect to Kilroy Long Beach Phase I, the Company's environmental
investigations revealed the site's possible prior use as a Nike air defense
command center or missile storage facility and the existence and use of former
and current underground storage tanks on or near the property. The Company's
investigation included whether the site might have been used previously for
the storage of missiles containing nuclear warheads, and did not reveal any
facts that would indicate that the prior use of the site would result in a
material risk of environmental liability. Consequently, the Company does not
believe that this site constitutes a risk of a liability that would have a
material adverse effect on the Company's financial condition or results of
operations taken as a whole. In connection with the preparation of the Phase I
environmental survey with respect to the Industrial Property located at 12752-
12822 Monarch Street, soil sampling revealed trace elements of contamination
with cleaning solvents. However, based on the level of contamination noted in
the environmental survey, management does not believe that such contamination
will have a material adverse effect on the Company's financial condition or
results of operations taken as a whole.

36
<PAGE>

None of the Company's environmental assessments of the other Properties has
revealed any environmental liability that the Company believes would have a
material adverse effect on the Company's financial condition or results of
operations taken as a whole, nor is the Company aware of any such material
environmental liability. Nonetheless, it is possible that the Company's
assessments do not reveal all environmental liabilities or that there are
material environmental liabilities of which the Company is unaware. Moreover,
there can be no assurance that (i) future laws, ordinances or regulations will
not impose any material environmental liability or (ii) the current
environmental condition of the Properties will not be affected by tenants, by
the condition of land or operations in the vicinity of the Properties (such as
the presence of underground storage tanks), or by third parties unrelated to
the Company. If compliance with the various laws and regulations, now existing
or hereafter adopted, exceeds the Company's budgets for such items, the
Company's ability to make expected distributions to stockholders could be
adversely affected.

Other Regulations. The Properties are also subject to various federal, state
and local regulatory requirements such as state and local fire and life safety
requirements. Failure to comply with these requirements could result in the
imposition of fines by governmental authorities or awards of damages to
private litigants. The Company believes that the Properties are currently in
material compliance with all such regulatory requirements. However, there can
be no assurance that these requirements will not be changed or that new
requirements will not be imposed which would require significant unanticipated
expenditures by the Company and could have an adverse effect on the Funds from
Operations and expected distributions.

The City of Los Angeles has enacted certain regulations relating to the
repair of welded steel moment frame buildings located in certain areas damaged
as a result of the Northridge earthquake in Southern California on January 17,
1994. As currently enacted, such regulations do not apply to the Properties.
There can be no assurance, however, that similar regulations will not be
adopted by governmental agencies with the ability to regulate the Properties,
that the Company will not acquire properties which may be subject to such
regulation or that other requirements affecting the Properties will not be
imposed which would require significant unanticipated expenditures by the
Company and could have a material adverse effect on the Funds from Operations
and cash available for distribution. The Company believes, based in part on
recent engineering reports, that its Properties are in good condition. See
"Business and Properties--Uninsured Losses from Seismic Activity."

Except as described in this Prospectus, there are no other laws or
regulations which have a material effect on the Company's operations, other
than typical state and local laws affecting the development and operation of
real property, such as zoning laws. See "Certain Provisions of Maryland Law
and of the Articles of Incorporation and Bylaws," "Partnership Agreement of
the Operating Partnership," "Federal Income Tax Consequences" and "ERISA
Considerations."

EFFECT OF MARKET INTEREST RATES ON PRICE OF COMMON STOCK. One of the factors
that will influence the market price of the Common Stock in public markets
will be the annual yield on the price paid for shares from distributions by
the Company. An increase in prevailing market interest rates on fixed income
securities may lead prospective purchasers of the Common Stock to demand a
higher annual yield from future distributions. Such an increase in the
required yield from distributions may adversely affect the market price of the
Common Stock. In addition, the market for equity securities can be volatile
and the trading price of the Common Stock could be subject to wide
fluctuations in response to operating results, news announcements, trading
volume, general market trends, changes in interest rates, governmental
regulatory action and changes in tax laws.

SHARES ELIGIBLE FOR FUTURE SALE. No prediction can be made as to the effect,
if any, that future sales of shares, or the availability of shares for future
sale, will have on the market price of the Common Stock. Sales of substantial
amounts of shares of Common Stock in the public market (or upon exchange of
Units) or the perception that such sales might occur could adversely affect
the market price of the shares of Common Stock.

Upon the consummation of the Offering, the Company will have 24,475,000
shares of Common Stock outstanding, of which all but the 100,000 restricted
shares of Common Stock will be freely tradable in the public market by persons
other than "affiliates" of the Company without restriction or registration
under the Securities

37
<PAGE>

Act. The remaining 100,000 restricted shares of Common Stock and all of the
shares of Common Stock that are issuable upon the redemption of limited
partnership Units will be deemed to be "restricted securities" within the
meaning of Rule 144 promulgated under the Securities Act ("Rule 144") and may
not be transferred unless registered under the Securities Act or an exemption
from registration is available, including any exemption from registration
provided under Rule 144. In general, upon satisfaction of certain conditions,
Rule 144 permits the sale of certain amounts of restricted securities one year
following the date of acquisition of the restricted securities from the
Company and, after two years, permits unlimited sales by persons unaffiliated
with the Company. In addition, the Commission has recently suggested further
revisions to the holding and volume limitations contained in Rule 144. The
adoption of amendments effecting such suggested revisions may result in
resales of restricted securities sooner than would be the case under Rule 144
as currently in effect. However, there can be no assurance of when, if ever,
such suggested amendments will be proposed or adopted.

The Operating Partnership presently has an aggregate of 2,817,476 limited
partnership Units issued and outstanding which may be redeemed by the
Operating Partnership on or after January 31, 1999 at the request of the
holders thereof for cash (based on the fair market value of an equivalent
number of shares of Common Stock at the time of such redemption) or, at the
Company's option, exchanged for an equal number of shares of Common Stock,
subject to certain anti-dilution adjustments and, with respect to 50% of the
Units issued to John B. Kilroy, Sr., John B. Kilroy, Jr. and KI, the
obligation of such Unitholders to indemnify the Company in connection with the
Formation Transactions. However, if the Company does not elect to exchange
such Units for shares, a Unitholder of such Units that is a corporation or a
limited liability company may require the Company to issue shares of Common
Stock in lieu of cash, subject to the Ownership Limit or, with the consent of
the Board of Directors, such other limit which does not result in the failure
of the Company to qualify as a REIT. See "Formation and Structure of the
Company" and "Shares Eligible for Future Sale--Redemption/Exchange Rights and
Registration Rights." The Company has granted options to purchase an aggregate
of approximately 1,185,000 shares of Common Stock to certain directors,
executive officers and other employees of the Company and an additional
approximately 215,000 shares of Common Stock have been reserved for issuance
either as restricted shares of Common Stock or upon the exercise of options
granted under the Stock Incentive Plan. See "Management--Stock Incentive
Plan." In addition, the Company may issue from time to time additional shares
of Common Stock or Units in connection with the acquisition of properties,
including the possible issuance of Units upon the exercise of options to
acquire the Option Properties. See "Prospectus Summary--Recent Developments--
Acquisitions," "The Company--Growth Strategies," "Business and Properties--
Acquired Properties" and "Business and Properties--Option Properties." The
Company has agreed to file and generally will keep continuously effective
beginning on January 31, 1999 a registration statement covering the issuance
of shares upon the exchange of limited partnership Units and the resale
thereof and has agreed to provide piggyback registration rights with respect
to shares of Common Stock which may be acquired by the Unitholders of such
Units and certain other persons. See "Shares Eligible for Future Sale." The
Company plans to file a registration statement with respect to the shares of
Common Stock issuable under the Stock Incentive Plan. Such registration
statements and registration rights generally will allow shares of Common Stock
covered thereby, including shares of Common Stock issuable upon exchange of
limited partnership Units or the exercise of options or restricted shares of
Common Stock to be transferred or resold without restriction under the
Securities Act.

In addition to the limits placed on the sale of shares of Common Stock by
operation of Rule 144 and other provisions of the Securities Act, (i) all but
four of the Unitholders (who hold an aggregate of 165,102 Units) have agreed
not to, directly or indirectly, offer, sell, offer to sell, contract to sell,
pledge, grant any option to purchase or otherwise dispose or transfer (or
announce any offer, sale, offer of sale, contract of sale, pledge, grant of
any option to purchase or other disposition or transfer) of any Units or
shares of Common Stock or other capital stock of the Company, or of securities
substantially similar thereto, or any other securities convertible into, or
exercisable or exchangeable for, any Units or shares of Common Stock or other
capital stock of the Company, or such similar securities, for a period of two
years from January 28, 1997 and (ii) four Unitholders who hold a total of
165,102 limited partnership Units agreed in connection with the issuance of
such Units not to exchange such Units for shares of Common Stock prior to
January 29, 1999. In addition, in connection with this Offering, the Company
has agreed not to, directly or indirectly, offer, sell, offer to sell,

38
<PAGE>

contract to sell, pledge, grant any option to purchase or otherwise dispose or
transfer (or announce any offer, sale, offer of sale, contract of sale,
pledge, grant of any option to purchase or other disposition or transfer) of
any (other than pursuant to the Stock Incentive Plan) Units or shares of
Common Stock or other capital stock of the Company, or of securities
substantially similar thereto, or any other securities convertible into, or
exercisable or exchangeable for, any Units or shares of Common Stock or other
capital stock of the Company, or such similar securities, for a period of 180
days from the date of this Prospectus, in each case without the prior written
consent of Prudential Securities Incorporated, on behalf of the Underwriters,
subject to certain limited exceptions. Prudential Securities Incorporated may,
at any time and without notice, release all or any portion of the securities
subject to such lock-up agreements. At the conclusion of such two-year period
on January 28, 1999, Common Stock issued upon the subsequent exchange of
limited partnership Units may be sold in the public market pursuant to the
registration rights described above. Notwithstanding the foregoing, 50% of the
Units received by John B. Kilroy, Sr., John B. Kilroy, Jr. and KI in
connection with the Formation Transactions have been pledged to secure their

THE COMPANY

GENERAL

Kilroy Realty Corporation was incorporated in September 1996 and commenced
operations upon the completion of its initial public offering on January 31,
1997. The Company was formed to continue and expand the real estate business
of the Kilroy Group, which, since 1947, has been engaged in the business of
real estate ownership, acquisition, development, leasing and management of
principally Class A suburban office and industrial buildings in prime
locations, primarily in Southern California. On January 31, 1997, the Company
completed an initial public offering of 12,500,000 shares of Common Stock. The
initial public offering price was $23.00 per share resulting in gross proceeds
of $287.5 million. On February 4, 1997, in connection with the initial public
offering, the underwriters exercised an over-allotment option and on February
7, 1997, pursuant to the terms of such over-allotment option, the Company
issued an additional 1,875,000 shares of Common Stock which resulted in gross
proceeds of $43,125,000. The aggregate proceeds to the Company of the IPO,
including the exercise of the underwriters' over-allotment option, net of
underwriters' discounts and commissions, advisory fees and offering costs,
were approximately $302.8 million. The Company operates as a self-administered
and self-managed real estate company and expects to qualify as a REIT for
federal and state income tax purposes beginning with the year ended December
31, 1997. See "Federal Income Tax Consequences--Taxation of the Company."

The Company's strategy has been to own, develop, acquire, lease and manage
Class A suburban office and industrial properties in select locations in key
suburban submarkets, primarily in Southern California, that the Company
believes have strategic advantages compared to neighboring submarkets. The
Properties offer tenants: (i) lower business taxes and operating expenses than
in adjoining submarkets; (ii) access to highly skilled labor markets; (iii)
strategic access to major transportation facilities such as freeways and
airports; (iv) proximity to the Los Angeles-Long Beach port complex, which
presently ranks as the largest commercial port in the United States; and (v)
for tenants with their names on certain Properties, visibility to freeway and
airplane travelers. As a result, the Properties attract major corporate
tenants and historically have achieved among the highest occupancy, tenant
retention and rental rates, both within their respective submarkets and as
compared to their respective neighboring submarkets. See "Business and
Properties."

The Company's portfolio of properties includes 33 office buildings
encompassing an aggregate of approximately 2.9 million rentable square feet
and 52 industrial buildings encompassing an aggregate of approximately 3.6
million rentable square feet. Thirty of the office buildings and 47 of the
industrial buildings are located in prime Southern California suburban
submarkets (including a complex of three office buildings located in El
Segundo, adjacent to LAX, presently the nation's second largest air-cargo
port, and a complex of five office buildings located adjacent to the Long
Beach Airport). The SeaTac Office Center is comprised of three office
buildings located adjacent to the Seattle-Tacoma International Airport. The
weighted average age of the Office Properties is approximately 14 years and
the weighted average age of the Industrial Properties is approximately 18
years. As of June 30, 1997, the Office Properties were approximately 88.1%
leased to 166 tenants, and the Industrial Properties were approximately 97.4%
leased to 166 tenants.

The Company's major tenants include, among others, Hughes Space &
Communications, a tenant since 1984, which is engaged in high-technology
commercial activities including satellite development and related applications
such as DirecTV, and other major tenants such as Sony Music Entertainment,
Boeing (giving effect to the Boeing Lease), M/R Systems, Mattel, Inc.,
Northwest Airlines, Inc. and Caltrans. The Company's strong relationships with
its tenants are evidenced by its average tenant retention rate (based upon
rentable square feet) for the period beginning January 1, 1994 and ending June
30, 1997, which was 74.1% for the Properties owned as of the date of the IPO
that were located in the counties of Los Angeles, Orange, Riverside, San
Bernardino and Ventura.

Since the completion of its IPO, the Company acquired or presently expects
to complete the acquisition of an aggregate of 19 suburban office properties
encompassing approximately 900,000 rentable square feet for an aggregate
acquisition cost (including expenses, closing costs and anticipated capital
expenditures) of approximately $107.9 million, and 40 industrial properties
encompassing approximately 2.2 million rentable

40
<PAGE>

square feet for an aggregate acquisition cost (including expenses, closing
costs and anticipated capital expenditures) of approximately $147.8 million.
For one Acquired Property, the acquisition cost was paid, in part, with the
issuance of 165,102 limited partnership Units. The issuance of the Units
permits sellers of properties to defer the recognition of all or part of the
taxable gain, if any, on the disposition of such properties. All but four of
the Acquired and Pending Properties are located in Southern California. Of the
Acquired and Pending Properties, 28 buildings are located in submarkets in
which the Company already owned office or industrial property at the
completion of the IPO, and 31 buildings are located in new submarkets within
Los Angeles County, Northern Orange County, Southern Orange County, Western
San Bernardino County, Northern San Diego County, Santa Clara County and
Placer County. Management believes that each of these new submarkets offers
significant growth opportunities. See "Business and Properties--The Company's
Principal Southern California Submarkets." As a result of these acquisitions,
the Company's aggregate rentable square feet of office and industrial space
increased by approximately 43.0% and 166.0%, respectively. In addition, the
Company is currently in active negotiations to purchase eight Pipeline
Properties, all of which are located in Southern California, for an aggregate
acquisition cost of approximately $68.0 million, including the assumption of
$14.0 million of mortgage indebtedness. No assurance can be given that the
Pending Acquisitions or the acquisition of the Pipeline Properties will be
consummated. See "Risk Factors--Real Estate Investment Considerations--Risks
of Real Estate Acquisitions and Development" and "Business and Properties--
Acquired Properties" and "--Pending Acquisitions."

The Company currently owns or has exclusive rights to develop approximately
60 acres of developable land (net of the acreage required for streets),
including (i) ten acres in Brea, California, (ii) 15 acres in Foothill Ranch
in Orange County, California, (iii) two and one-half acres in Anaheim,
California, (iv) three and one-half acres in Irvine, California, (v) five
acres in Camarillo, California and (vi) 24 acres at Kilroy Airport Center Long
Beach. Management believes that it can build up to 1.6 million rentable square
feet on the Development Properties, subject to required entitlements and other
governmental approvals, of which approximately 500,000 rentable square feet is
planned for development beginning in 1997. The Company may engage in the
development of office or industrial properties when market conditions support
a favorable risk-adjusted rate of return on such development. No assurance can
be given that the Company will commence any development, or that, if
commenced, any such development will be completed. See "Risk Factors--Real
Estate Investment Considerations--Risks of Real Estate Acquisition and
Development" and "Business and Properties--Development, Leasing and Management
Activities--Kilroy Airport Center, Long Beach."

The Company also has focused on the design and construction of its projects.
The Office Properties developed by the Company (Kilroy Airport Center at El
Segundo, Kilroy Airport Center Long Beach and SeaTac Office Center) were
designed and developed to above-standard specifications, with an emphasis on
long-term operating efficiency and tenant comfort. The Industrial Properties
developed by the Company also were designed and developed to provide above-
standard quality and meet the long-term needs of tenants and were designed as
multi-use facilities to satisfy various types of manufacturing, distribution
and office uses. As a result, these Industrial Properties continue to serve
the evolving needs of their tenants, some of which have recently invested
substantially in long-term tenant improvements. See "Business and Properties--
Office Properties" and "--Industrial Properties."

The Company has created value by effectively working with municipalities,
large landowners and other members of the real estate community in Southern
California, and has maintained strong relationships at all levels of
government, as well as with financial institutions and major corporate
tenants. In 1981, the Company initiated the El Segundo Employers' Association,
a traffic and management organization composed of major employers in the El
Segundo area in which the Company owns four Office Properties and four
Industrial Properties. The organization has worked with local government and
has been instrumental in the furtherance of infrastructure developments in El
Segundo and throughout the surrounding area, including two recent developments
that management believes will have a substantial economic benefit to the El
Segundo submarket. First, in October 1994, Interstate Highway I-105 (the "I-
105 Freeway") opened, which crosses Los Angeles from east to west and provides
substantially improved access to El Segundo and LAX. A second infrastructure

41
<PAGE>

development in the El Segundo submarket is a major east-west grade-separated
light rail commuter line (the "Green Line"). The Green Line runs adjacent to
Kilroy Airport Center at El Segundo. Management believes that the Green Line,
which opened in August 1995, will add significant value to the El Segundo
submarket.

The Company believes that the foundation for its growth in future years will
be the strengthening Southern California economy, the quality and strategic
location of its Properties, the economic benefits of its submarkets to
tenants, its conservative capital structure, its access to public capital
markets, the lack of new construction of office properties in its submarkets,
its access to developable properties, the knowledge and experience of its
senior management team and its long-term relationships with large Southern
California corporate tenants, municipalities, landowners and institutional
sellers. In addition, the Company believes that it is one of a limited number
of REITs focusing on office and industrial properties and that it is the only
REIT with a 50-year operating history concentrating primarily on the
acquisition and development of suburban Southern California office and
industrial properties.

During the remainder of the Company's first year of operations, the Company
expects sources of potential growth in cash available for distribution
through: (i) the further leasing of its available space of approximately
230,000 rentable square feet, as of June 30, 1997; (ii) the renewal of leases
at higher rents; and (iii) the acquisition of strategic properties with Units
and/or available cash and borrowings under the Credit Facility and the
Company's approximately $88.8 million of cash available for acquisitions and
property development upon consummation of the Offering. In the Company's
second year of operations, the Company expects sources of potential growth in
cash available for distribution through: (i) contractual increases in base
rent payments from tenants; (ii) continued leasing of available space; (iii)
the acquisition of strategic properties; and (iv) the contemplated completion
of certain development activities. Although the Company paid distributions to
holders of its Common Stock for the periods ended March 31 and June 30, 1997,
there can be no assurance that the Company will achieve any growth in cash
available for distribution, that available space will be leased, that leases
scheduled to expire will be renewed or that the Company will successfully
acquire additional properties or complete any of its planned development
activities. See "Risk Factors--Real Estate Investment Considerations--Risks of
Real Estate Acquisition and Development."

As of June 30, 1997, the Company (primarily through the Operating
Partnership and the Services Company) employed 58 persons, 43 of whom are
located at the Company's headquarters at Kilroy Airport Center in El Segundo,
California. The Company believes that relations with its employees are good.
The Company's executive officers have been with the Company for an average of
approximately 13 years. As of June 30, 1997, after giving effect to the
Offering, the Company's executive officers and directors (and certain of their
affiliates) owned in the aggregate 10.1% of the Common Stock (or interests
exchangeable therefor).

Kilroy Realty Corporation, a Maryland corporation, has executive offices at
2250 East Imperial Highway, El Segundo, California 90245, and its telephone
number is (213) 772-1193.

GROWTH STRATEGIES

42
<PAGE>

most of the Properties are located; (ii) the presence of inadvertent owners
(through foreclosure or otherwise) of office and industrial properties in the
Company's submarkets, as well as the Company's ability to acquire properties
with Units (thereby permitting a seller to defer taxable gain), both of which
create enhanced acquisition opportunities; (iii) the quality and location of
the Properties; and (iv) the Company's access to acquisition and development
opportunities as a result of its significant relationships 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 exploit 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. In addition, the Company believes that
public ownership and its conservative capital structure will provide new
opportunities for growth. There can be no assurance, however, that the Company
will be able to lease available space, complete any property acquisitions,
successfully develop any land acquired or improve the operating results of any
developed properties that are acquired. See "Business and Properties--
Development, Leasing and Management Activities."

The Company believes that the strength of its leasing is demonstrated by the
Company's leasing activity since 1993. In the period from January 1, 1993 to
June 30, 1997, the Company leased or renewed leases for an aggregate of
approximately 1.2 million rentable square feet of office space and
approximately 786,000 rentable square feet of industrial space. As of June 30,
1997, the Office Properties in Southern California were approximately 98.3%
leased, as compared to approximately 83.7% occupancy rates for all office
properties in Southern California as of March 31, 1997. As of June 30, 1997,
the Industrial Properties in Southern California were approximately 97.0%
leased, as compared to approximately 92.7% occupancy rates for all industrial
properties in Southern California as of March 31, 1997. See "Business and
Properties--General" and "--Occupancy and Rental Information."

The Company's 20 largest tenants represented approximately 54.0% of annual
base rent for the year ended December 31, 1996 (giving pro forma effect to the
Boeing Lease). Of this amount, its largest tenant, Hughes Space &
Communications, currently leases approximately 530,000 rentable square feet of
office space, representing approximately 15.9% of the Company's total base
rent for the year ended December 31, 1996 giving pro forma effect to the
Acquired and Pending Properties and the Boeing Lease. The base periods of the
Hughes Space & Communications leases expire beginning in January 1999. The
Company's revenues and cash available for distribution to stockholders would
be disproportionately and materially adversely affected in the event of
bankruptcy or insolvency of, or a downturn in the business of, or the
nonrenewal of leases by, any of its significant tenants, or the renewal of
such leases on terms less favorable to the Company than their current terms.

Approximately 1.0 million aggregate rentable square feet in the Properties,
owned by the Company as of the date of its IPO, was leased by the Company from
January 1, 1992 through December 31, 1994, a period which management
characterizes as recessionary. Based on the leases the Company signed in 1996,
and the findings in an independent study of the Southern California real
estate market commissioned by the Company, management believes that the recent
trend toward increasing rental rates in Class A office and industrial
buildings in the Company's Southern California submarkets presents significant
opportunities for growth. In addition, as of June 30, 1997, approximately
58.5% of the Company's rentable square feet is subject to leases expiring in
2000 or beyond, when management expects asking rents for the respective
Properties to be higher than the rents paid pursuant to such leases. In
addition, as of June 30, 1997, approximately 20.6% of the Company's total base
rent (representing approximately 10.2% of the aggregate rentable square feet
of the Properties) was attributable

43
<PAGE>

to leases with CPI increases and approximately 34.5% of the Company's total
base rent (representing approximately 37.7% of the aggregate rentable square
feet of the Properties) was attributable to leases with other specified
contractual increases. No assurance can be given, however, that new leases
will reflect rental rates greater than or equal to current rental rates or
that current or future economic conditions will support higher rental rates.
See "Risk Factors--Real Estate Investment Considerations."

Acquisition Strategies. The Company seeks to increase its cash available for
distribution by acquiring additional quality office and industrial properties,
including properties that: (i) may provide attractive initial yields with
significant potential for growth in cash flow from property operations; (ii)
are strategically located, of high quality and competitive in their respective
submarkets; (iii) are located in the Company's existing submarkets and/or in
other strategic submarkets where the demand for office and industrial space
exceeds available supply; or (iv) have been under-managed or are otherwise
capable of improved performance through intensive management and leasing that
will result in increased occupancy and rental revenues. The Company believes
that the Southern California market is an established and mature real estate
market in which property owners generally have a low tax basis (and,
accordingly, the potential for large taxable gains) in their properties.
Management believes that the Company's significant Southern California
relationships, extensive experience, conservative capital structure and
ability to acquire properties for Units, and thereby defer a seller's taxable
gain, if any, will enhance the ability of the Company to consummate
transactions quickly and to structure more competitive acquisitions than other
real estate companies in the market which lack its access to capital or the
ability to issue Units. See "Business and Properties--Development, Leasing and
Management Activities."

As of June 30, 1997, the Company had entered into agreements to acquire the
Pending Acquisitions. The Pending Acquisitions are comprised of 11 industrial
buildings encompassing approximately 697,000 rentable square feet for an
aggregate acquisition cost of $57.5 million, seven of the buildings are
located in Southern California. In addition, the Company is currently in
active negotiations to purchase eight Pipeline Properties for an aggregate
acquisition cost of $68.0 million, including the assumption of $14.0 million
of mortgage indebtedness. All of the Pipeline Properties are located in
Southern California. In addition, on July 30, 1997, the Company entered into
the Allen LOI. There can be no assurance, however, that the Company will be
able to complete any property acquisitions, successfully develop any land
acquired or improve the operating results of any developed properties that are
acquired. See "Prospectus Summary--Recent Developments--Acquisitions" and
"Business and Properties--Acquired Properties," "--Pending Acquisitions" and
"--The Allen Group Letter of Intent."

Development Strategies. Since 1947, the Company and its predecessors have
developed millions of rentable square feet of office and industrial space,
including high technology facilities, primarily located in Southern
California, for its own portfolio and for third parties. The Company currently
owns an aggregate of approximately 36 acres of developable land comprised of
ten acres of developable land in Brea, 15 acres in Foothill Ranch in Orange
County, two and one-half acres in Anaheim, three and one-half acres in Irvine
and five acres in Camarillo. The Company is the master ground lessee of, and
has sole development rights to, the 24 acres of developable land entitled for
office, research and development, light industrial and other commercial
projects at Kilroy Airport Center Long Beach. All of the developable land is
located in Southern California. Management believes that the aggregate 60
acres of developable land provide the Company with significant growth
opportunities.

The Company presently plans to develop an aggregate of up to 1.6 million
rentable square feet of office or industrial space on the Development
Properties, subject to required entitlements and other governmental approvals.
Of this amount, the Company plans to commence development of approximately
500,000 rentable square feet of industrial space in 1997 at a total budgeted
cost of approximately $25.0 million. No assurance can be given that the
Company will commence any development, or that, if commenced, any such
development will be completed. See "Risk Factors--Real Estate Investment
Considerations--Risks of Real Estate Acquisition and Development" and
"Business and Properties--Development, Leasing and Management Activities--
Kilroy Airport Center, Long Beach."

44
<PAGE>

Financing Policies. The Company's financing policies and objectives are
determined by the Board of Directors. The Company presently limits the 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) to
approximately 50%. However, such objectives may be altered 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. The total
debt constituted, as of June 30, 1997, approximately 29.9% of the total market
capitalization of the Company. Giving pro forma effect to the Offering and the
application of the estimated net proceeds from the Offering, total debt, as of
July 31, 1997, would have constituted approximately 12.1% of the total market
capitalization of the Company. The Company intends to utilize one or more
sources of capital for future acquisitions, development and capital
improvements, which may include undistributed cash flow, borrowings under the
Credit Facility, the Company's approximately $88.8 million of cash available
for acquisition and development out of the net proceeds of the Offering,
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 for any such acquisitions, developments or improvements on
terms favorable to the Company. See "Prospectus Summary--Growth Strategies"
and "Business and Properties--Development, Leasing and Management Activities."

45
<PAGE>

USE OF PROCEEDS

The net proceeds to the Company from the sale of Common Stock in the
Offering, after the deduction of underwriting discounts and commissions and
estimated offering expenses, are expected to be approximately $241.3 million
(approximately $277.6 million if the Underwriters' over-allotment option is
exercised in full). The Company intends to contribute all of the net proceeds
of the Offering to the Operating Partnership in exchange for Units, and the
Operating Partnership will apply the net proceeds of the Offering as follows:

<TABLE>
<CAPTION>
AMOUNT
--------------
(IN THOUSANDS)
<S> <C>
Repayment of outstanding borrowings under the Credit
Facility................................................... $ 95,000
Aggregate acquisition cost of the Pending Acquisitions...... 57,500
Cash available for acquisitions, development and working
capital.................................................... 88,800
--------
Total..................................................... $241,300
========
</TABLE>

In the event that the Underwriters' over-allotment option is exercised in
full, the net proceeds thereof will be used by the Company for additional
working capital and will be available for development and for acquisitions of
properties not yet identified. Pending the application of such net proceeds,
the Company will invest the net proceeds in interest-bearing accounts and
short-term, interest-bearing securities, which are consistent with the
Company's intention to qualify for taxation as a REIT. Such investments may
include, for example, obligations of the Governmental National Mortgage
Association, other government and government agency securities, certificates
of deposit and interest-bearing bank deposits.

Substantially all of the $95.0 million of borrowings outstanding under the
Credit Facility expected to be repaid with the proceeds of this Offering were
used to finance the acquisition of the Acquired and Pending Properties. At
June 30, 1997, the amount outstanding under the Credit Facility bore a
weighted average interest rate of 7.5%. It is expected that the Credit
Facility after the application of the estimated net proceeds of the Offering
will be available for future property acquisitions, development and working
capital. In addition, the Company is currently in active negotiations to
purchase eight Pipeline Properties for an approximate aggregate acquisition
cost of $68.0 million, including the assumption of $14.0 million of mortgage
indebtedness.

On July 30, 1997, the Company signed the Allen LOI to acquire the principal
assets of Allen which include 1.7 million rentable square feet of completed
and under construction office and industrial properties, and developable land,
located primarily in Northern San Diego County. If consummated, the Company
would purchase the assets in phases over the next several years for a total
investment currently estimated to exceed $300 million, $85 million of which
could be spent by year-end 1997. The acquisition is subject to the completion
of due diligence and the negotiation of final documentation. No assurance can
be given that the transactions contemplated by the Allen LOI will be
consummated or, if consummated, successfully managed and/or developed by the
Company. See "Risk Factors--Real Estate Investment Considerations--Risks of
Real Estate Acquisition and Development," "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Liquidity and
Capital Resources" and "Business and Properties--The Allen Group Letter of
Intent."

PRICE RANGE OF COMMON STOCK AND DISTRIBUTION HISTORY

The Common Stock began trading on the NYSE on January 29, 1997 under the
symbol "KRC." On August 14, 1997, the last reported sales price per share of
Common Stock on the NYSE was $25.50. As of June 30, 1997, there were
approximately 38 holders of record of the Common Stock (excluding beneficial
owners whose shares are held in the name of CEDE & Co.). The following table
sets forth quarterly high and low closing sales prices per share of the Common
Stock reported on the NYSE and the distributions paid by the Company with
respect to each such period.

<TABLE>
<CAPTION>
PERIOD HIGH LOW DISTRIBUTION
- ------ --------- ------- ------------
<S> <C> <C> <C>
January 29, 1997 to March 31, 1997.............. $28 1/8 $24 7/8 $0.2583(1)
April 1, 1997 to June 30, 1997.................. $26 5/8 $23 1/8 $0.3875
July 1, 1997 to August 14, 1997................. $26 15/16 $24
</TABLE>
- --------
(1) The Company paid a distribution of $0.2583 per share of Common Stock on
May 30, 1997 for the period February 1, 1997 through March 31, 1997, which
is approximately equivalent to a quarterly distribution of $0.3875 per
share or an annual distribution of $1.55 per share of Common Stock.

Units and shares of Common Stock will receive equal distributions. Future
distributions by the Company will be at the discretion of the Board of
Directors and will depend on the actual Funds from Operations, its financial
condition, its capital requirements, the annual distribution requirements
under the REIT provisions of the Code (see "Federal Income Tax
Considerations--Taxation of the Company--Requirements for Qualification"), and
such other factors as the Board of Directors deems relevant. See "Risk
Factors--Changes in Investment and Financing Policies Without Stockholder
Vote." To obtain and maintain its qualification as a REIT, the Company must
make annual distributions to stockholders of at least 95% of its taxable
income, determined without regard to the deduction for dividends paid and by
excluding any net capital gains. Under certain circumstances, the Company may
be required to make distributions in excess of cash flow available for
distribution to meet such distribution requirements. There can be no assurance
that any such distributions will be made by the Company.

The Company anticipates that its cash available for distribution will exceed
earnings and profits due to non-cash expenses, primarily depreciation and
amortization, to be incurred by the Company. Distributions by the Company to
the extent of its current or accumulated earnings and profits for federal
income tax purposes, other than capital gain dividends, will be taxable to
stockholders as ordinary dividend income. Capital gain distributions generally
will be treated as long-term capital gains. Distributions in excess of
earnings and profits generally will be treated as a non-taxable return of
capital to the extent of each stockholder's basis in his or her Common Stock
to the extent thereof, and thereafter as taxable gain. The non-taxable
distributions will reduce each stockholder's tax basis in the Common Stock
and, therefore, the gain (or loss) recognized on the sale of such Common Stock
or upon liquidation of the Company will be increased (or decreased)
accordingly. Distributions that are treated as a reduction of the
stockholder's basis in its shares of Common Stock will have the effect of
deferring taxation until the sale of the stockholder's shares. The Company has
determined that, for federal income tax purposes, approximately 13.7% of the
distributions paid for the Company's first year of operations which commenced
on January 31, 1997 will represent return of capital to stockholders. Given
the dynamic nature of the Company's acquisition strategy and the extent to
which any future acquisitions would alter this calculation, no assurances can
be given regarding what percent of future distributions will constitute return
of capital for federal income tax purposes. If actual cash available for
distribution or taxable income vary from these amounts, the percentage of
distributions which represent a return of capital may be materially different.
For a discussion of the tax treatment of distributions to holders of Common
Stock, see "Federal Income Tax Consequences--Taxation of Taxable U.S.
Stockholders Generally" and "--Taxation of Non-U.S. Stockholders." In order to
qualify to be taxed as a REIT, the Company must make annual distributions to
stockholders of at least 95% of its REIT taxable income (determined without
regard to the dividends received deduction and by excluding any net capital
gains) which the Company anticipates will be less than its share of adjusted
Funds from Operations. Under certain circumstances, the Company may be
required to make distributions in excess of cash available for distribution in
order to meet such distribution requirements.

47
<PAGE>

Financing activities such as repayment or refinancing of loans also may
affect the Company's assets and liabilities and the amount of cash available
for distribution for future periods. Management seeks to control the timing
and nature of investing and financing activities in order to maximize the
Company's return on invested capital.

Future distributions by the Company are subject to the requirements of the
MGCL and the discretion of the Board of Directors, and depend on the actual
cash flow of the Company, its financial condition, its capital requirements,
any decision by the Board of Directors to reinvest the Operating Partnership's
Funds from Operations rather than distribute such funds to the Company, the
annual distribution requirements under the REIT provisions of the Code (see
"Federal Income Tax Considerations--Taxation of the Company--Annual
Distribution Requirements") and such other factors as the Board of Directors
deems relevant. There can be no assurance that any distributions will be made
or that the expected level of distributions will be maintained by the Company.
See "Risk Factors--Real Estate Investment Considerations." If revenues
generated by the Company's properties in future periods decrease materially
from current levels, the Company's ability to make expected distributions
would be materially adversely affected, which could result in a decrease in
the market price of the shares of Common Stock.

The Company may in the future implement a distribution reinvestment program
under which holders of shares of Common Stock may elect automatically to
reinvest distributions in additional shares of Common Stock. The Company may,
from time to time, repurchase shares of Common Stock in the open market for
purposes of fulfilling its obligations under this distribution reinvestment
program, if adopted, or may elect to issue additional shares of Common Stock.
If the Company adopts a distribution reinvestment program, it will solicit
participation in the program after the Offering by means of a separate
prospectus, and a purchase of shares of Common Stock in the Offering does not
entitle any investor to participate in any such program. There can be no
assurance that the Company will adopt such a program, and consequently, the
probable date of adoption or number of shares of Common Stock that would be
available under such program cannot be determined at this time.

The Company provides its stockholders with annual reports containing audited
financial statements with a report thereon by the Company's independent
auditors, together with management's discussion and analysis, as required
under applicable rules and regulations of the Securities and Exchange
Commission (the "Commission").

(1) Pro forma net income per share equals pro forma net income divided by the

(2) As defined by NAREIT, "Funds from Operations" represents net income (loss)
before minority interest of 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 Funds from
Operations were as follows: in all periods, depreciation and amortization;
in 1996, 1995 and 1994, gains on extinguishment of debt; and in pro forma
1997 and 1996, and in the six months ended June 30, 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 industry analysts have accepted it as such. 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 such
other REITs. Further, Funds from Operations does not represent amounts
available for management's discretionary use because of needed capital
replacement or expansion, debt service obligations, or other commitments
and uncertainties. See the notes to the historical financial statements of
the Kilroy Group. Funds from Operations should not be considered as an
alternative for net income as a measure of profitability nor is it
comparable to cash flows provided by operating activities determined in
accordance with GAAP.

(3) Funds from Operations and cash flow information is comprised 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 June 30, 1997.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion should be read in conjunction with the "Selected
Financial Data" and the Consolidated Financial Statements of the Company and
the Combined Financial Statements for the Kilroy Group and notes thereto
appearing elsewhere in this Prospectus. The Combined Financial Statements of
the Kilroy Group are comprised of the operations, assets and liabilities of
the Properties contributed to the Company by the Kilroy Group in connection
with the Formation Transactions. For accounting purposes, the financial
information of the Operating Partnership and the Company are consolidated.

RESULTS OF OPERATIONS

The Company's management believes that in order to provide meaningful
historical analysis of the financial statements, certain adjustments must be
made to the historical Kilroy Group financial statements to make accounting
periods comparable. Accordingly the results of operations for the period
January 1, 1997 to January 31, 1997 have been adjusted to reflect interest
income, general and administrative expenses, interest expense and
extraordinary items as if the IPO and Formation Transactions had been
consummated on January 1, 1997. The following sections discuss the results of
operations as adjusted.

Total revenues increased $7.2 million, or 36.4%, for the six months ended
June 30, 1997 compared to the same period in 1996. Rental income increased
$4.6 million, or 26.3%, to $22.2 million for the six months ended June 30,
1997 compared to $17.6 million in the same period in 1996. Rental income from
office properties increased $3.4 million during the six months ended June 30,
1997 from the comparable period in 1996. This improvement was attributable to
an increase in office space under lease from 1,298,000 rentable square feet at
June 30, 1996 to 2,414,000 rentable square feet at June 30, 1997, an increase
of 1,116,000 rentable square feet. Approximately 343,000 rentable square feet
reflects four office properties acquired in connection with the IPO and
711,000 rentable square feet reflects sixteen office buildings purchased
during the three months ended

53
<PAGE>

June 30, 1997. The remaining increase is primarily the result of leasing at
Kilroy Airport Center at El Segundo and Kilroy Airport Center, Long Beach. The
increase in rentable square footage under lease was offset by a decrease in
average rent per rentable square foot at Kilroy Airport Center at El Segundo,
from $21.51 per square foot for the six months ended June 30, 1996 to $19.97
for the same period in 1997 as a result of the re-negotiation and extension of
a lease with Hughes Space and Communications in November 1996. Rental income
from industrial properties increased $1.2 million during the six months ended
June 30, 1997 compared to the same period in 1996. The increase was due to the
purchase of three industrial buildings in connection with the IPO with
approximately 380,000 rentable square feet under lease at June 30, 1997, and
the purchase of 26 industrial buildings during the three months ended June 30,
1997 with approximately 1,101,000 rentable square feet under lease. Tenant
reimbursements increased to $2.1 million for the six months ended June 30,
1997 from $1.8 million for the same period in 1996. The $0.3 million increase
was primarily attributable to tenant reimbursements in connection with the
office and industrial buildings purchased in connection with and subsequent to
the IPO. Interest income increased $2.5 million as a result of interest earned
on the $116.2 million of net IPO proceeds remaining after the purchase of
properties and the repayment of debt in connection with the IPO. Other income
for the six months ended June 30, 1997 includes a $0.1 million gain on the
sale of furniture and equipment and $0.1 million in revenues which were
previously written-off as uncollectible.

Expenses for the six months ended June 30, 1997 decreased by $2.6 million,
or 12.7%, to $18.4 million compared to $21.0 million for the six months ended
June 30, 1996. Property expenses and real estate taxes increased $0.6 million
and $0.4 million, respectively, during the six months ended June 30, 1997 over
the same period in 1996 primarily due to the properties purchased in
connection with the IPO. Ground lease expense increased $0.1 million during
the six months ended June 30, 1997 over the same period in 1996 as a result of
one additional ground lease with respect to one of the properties purchased in
connection with the IPO. Interest expense decreased $5.9 million, or 54.8%, to
$4.8 million for the six months ended June 30, 1997 from $10.7 million for the
six months ended June 30, 1996, primarily as a result of the repayment of
$127.4 million in debt in connection with the IPO. See "Liquidity and Capital
Resources."

Net income was $8.7 million for the six months ended June 30, 1997 compared
to a $1.2 million loss for the same period in 1996. The net change of $9.9
million is due primarily to an increase in rental income of $4.6 million, an
increase in interest income of $2.5 million and a decrease in interest expense
of $5.9 million which were partially offset by an increase of $1.5 million in
general and administrative expense and an increase of $1.0 million in
depreciation and amortization.

Year Ended December 31, 1996 Compared to Year Ended December 31, 1995

Total revenues decreased $3.7 million, or 8.7%, for the year ended December
31, 1996 compared to the same period for 1995. Rental income increased $1.1
million, or 3.3%, to $35.0 million for the year ended December 31, 1996
compared to $33.9 million for the same period in 1995. Rents from office
properties contributed by the Kilroy Group increased $0.8 million during the
year ended December 31, 1996 from the comparable period in 1995. Such increase
was due to office space under lease increasing from 1,222,000 rentable square
feet at December 31, 1995 to 1,284,000 rentable square feet at December 31,
1996. The majority of this increase relates to leasing at Kilroy Airport
Center Long Beach. There was no significant change in rent per rentable square
foot for the year ended 1996 compared to the year ended 1995. Rents from
Industrial Properties contributed by the Kilroy Group increased $0.3 million
during the year ended December 31, 1996 compared to the same period in 1995.
The increase resulted from a lease with a CPI increase and the effect of the
2260 E. El Segundo Boulevard building being leased for the entire twelve
months ended December 31, 1996. Tenant reimbursements increased to $3.4
million, in 1996 compared to $3.0 million for 1995. The $0.4 million increase
is primarily due to increased billable operating expenses resulting from new
leases. Revenues for 1995 include a gain on the sale of air rights of $4.5
million at Kilroy Airport Center at El Segundo. See Note 2 to the Combined
Financial Statements.

Expenses in the year ended December 31, 1996 increased by $0.4 million, or
1.0%, to $46.0 million compared to $45.6 million for the same period in 1995.
During the year ended December 31, 1996, the Company accrued the costs of an
option buy out of $3.15 million for the cancellation of an option to purchase
a 50% equity

54
<PAGE>

interest in Kilroy Airport Center at El Segundo. Interest expense decreased
$2.3 million, or 9.6%, to $21.9 million in calendar 1996 from $24.2 million in
calendar 1995, primarily as a result of the forgiveness and restructuring of
certain debt in 1996. See Note 4 to the Combined Financial Statements.

Net income was $13.3 million for the year ended December 31, 1996 compared
to $12.6 million for the same period in 1995. The increase of $0.7 million is
due primarily to a decrease in interest expense of $2.3 million, an increase
in extraordinary gains of $4.8 million less the nonrecurring option buy out
cost of $3.15 million for calendar 1996 and the sale of air rights of $4.5
million in calendar 1995.

Year Ended December 31, 1995 Compared to Year Ended December 31, 1994

Total revenues increased $6.7 million, or 18.5%, for the year ended December
31, 1995 compared to the year ended December 31, 1994. Rental income increased
$1.3 million, or 4.0%, to $33.9 million in calendar 1995 from $32.6 million in
calendar 1994. In calendar 1995, rents from industrial properties contributed
by the Kilroy Group increased $0.8 million from the year ended December 31,
1994, primarily due to the effect of 12-months' rental for the Property
located at 2265 E. El Segundo Boulevard compared to four-months' rental in
calendar 1994. Office square footage and average rent per rentable square foot
remained relatively unchanged for the year ended December 31, 1995 compared to
the year ended December 31, 1994. Industrial square footage under lease
increased to 902,000 at December 31, 1995 as compared to 730,000 at December
31, 1994. The 2260 E. El Segundo Boulevard building was leased in April 1995
after being vacant during 1994. The Company also leased the 1230 S. Lewis St.
property in February 1995 at a rate of $6.11 per rentable square foot, down
from the rate of $6.43 in effect for the prior year. Tenant reimbursements
increased to $3.0 million for the year ended December 31, 1995 from $1.6
million for the year ended December 31, 1994 due principally to the 1994
$1.5 million refund to tenants for property tax refunds. Parking revenues
increased to $1.6 million in 1995 from $1.4 million for the year ended
December 31, 1994 due to recognition of 12-months' parking income for Kilroy
Airport Center Long Beach in calendar 1995 compared to two months in calendar
1994, together with increased tenant parking revenues at Kilroy Airport Center
at El Segundo. Revenues for the year ended December 31, 1995 include a gain on
the sale of air rights of $4.5 million referred to above. Other income
decreased $0.5 million to $0.3 million during calendar 1995 compared to
calendar 1994, primarily as a result of nonrecurring interest income of $0.4
million in 1994 on the property tax refunds referred to below.

Expenses for the year ended December 31, 1995 increased $0.8 million, or
1.8%, to $45.6 million. Property operating expenses increased $0.8 million, or
13.9%, primarily due to increased utility costs, increases in employee wages
and benefits and a $0.3 million management fee paid to KI to cover costs of
the loan renegotiation at Kilroy Airport Center at El Segundo. Real estate
taxes increased $1.9 million, to $1.4 million in 1995 from a credit balance of
$0.4 million for the year ended December 31, 1994, primarily due to the
$2.4 million property tax refund recorded by the Company for the year ended
December 31, 1994 and the effect of a reduction in aggregate assessed property
values for the year ended December 31, 1995. General and administrative
expenses decreased $0.3 million, or 12.0%, to $2.2 million for the year ended
December 31, 1995 from $2.5 million for the year ended December 31, 1994
period, primarily due to a $0.3 million penalty for late payment of property
taxes in calendar 1994. Interest expense decreased $1.2 million to $24.2
million in 1995 from $25.4 million for the year ended December 31, 1994 due to
the September 1995 extension of the mortgage on Kilroy Airport Center at El
Segundo at a lower interest rate and the forgiveness of certain debt, offset
in part by the effect of higher interest rates on the variable rate mortgage
secured by Kilroy Airport Center Long Beach. See Note 4 to the Combined
Financial Statements. Ground lease expense decreased $0.1 million to $0.8
million for the year ended December 31, 1995, reflecting the effect of 12
months' reduction of ground rent for Phase III of Kilroy Airport Center Long
Beach compared to six months for the year ended December 31, 1994. The
$0.5 million decrease in depreciation and amortization to $9.5 million for the
year ended December 31, 1995 results from certain assets becoming fully
amortized.

Net income increased $19.3 million to $12.6 million for the year ended
December 31, 1995 compared to a net loss of $6.7 million for the year ended
December 31, 1994, primarily due to the sale of air rights discussed above and
a $13.4 million increase in gains on extinguishment of debt to $15.3 million
for the year ended December 31,1995 compared to $1.8 million for the year
ended December 31, 1994.

LIQUIDITY AND CAPITAL RESOURCES

Upon the consummation of the Offering and the use of proceeds therefrom (as
described under the caption "Use of Proceeds"), the Company will have (i)
repaid its outstanding indebtedness under the Credit Facility of $95.0 million
and (ii) cash available for acquisitions, development and working capital of
approximately $88.8 million. The Credit Facility is used primarily to finance
acquisitions of additional properties. The availability of funds under the
Credit Facility is subject to, among other things, the value of the underlying
collateral securing it. The Company has recently received a commitment to
increase the availability under the Credit Facility to $200.0 million.

Subsequent to its IPO, the Company purchased approximately $198.2 million of
office and industrial properties. The purchase price for such Properties was
funded out of net proceeds of the IPO, from borrowings under the Credit
Facility, working capital and, in the case of one Acquired Property, in part,
in Units. The Company has also entered into agreements to purchase the Pending
Acquisitions for an approximate acquisition cost (including expenses, closing
costs and anticipated capital expenditures) of approximately $57.5 million.
See "Prospectus Summary--Recent Developments--Acquisitions," "Business and
Properties--Acquired Properties" and "--Pending Acquisitions." The Company is
currently in active negotiations to purchase an additional eight Pipeline
Properties for an aggregate acquisition cost of $68.0 million, including the
assumption of $14.0 million of mortgage indebtedness. The Company anticipates
that such acquisitions, if consummated, would be funded with net proceeds from
this Offering, funds available under the Credit Facility and working capital.

The Company presently plans to develop an aggregate of 1.6 million rentable
square feet of office or industrial space on the Development Properties,
subject to required entitlements. Of this amount, the Company plans to
commence development of 500,000 rentable square feet of industrial space in
1997 at a total budgeted cost of $25.0 million. The Company expects to finance
such development with net proceeds from this Offering, borrowings under the
Credit Facility and working capital. The Company presently has no financial
commitments in its capacity as a developer of real estate projects.

In June 1997, the Company entered into the Boeing Lease for approximately
211,000 rentable square feet of office space at the SeaTac Office Center. In
connection with the Boeing Lease, the Company agreed to make $3.25 million of
tenant improvements which the Company presently expects to fund from working
capital or borrowings under the Credit Facility. The Company anticipates that
such tenant improvements will be completed by December 31, 1997. The Company
also expects to spend approximately $2.0 million in connection with non-
recurring capital improvements at SeaTac Office Center, and to incur
additional tenant improvement and leasing commission costs at SeaTac in
connection with the further lease-up of approximately 96,000 rentable square
feet.

The Company also expects to incur $500,000 of earthquake-related
improvements to certain of the Properties in the next six months. A reserve
for this amount has been established pursuant to the $84.0 Million Loan. See
"Description of Indebtedness--The $84.0 Million Loan."

On July 30, 1997, the Company signed the Allen LOI to acquire the principal
assets of Allen which include approximately 1.7 million rentable square feet
of completed and under construction office and industrial properties, and
developable land, located primarily in Northern San Diego County. If
consummated, the Company would purchase the assets in phases over the next
several years for a total investment currently estimated to exceed $300
million, $85 million of which could be invested by the end of 1997. The
acquisition is subject to the completion of due diligence and the negotiation
of final documentation. If the Company enters into the transactions
contemplated by the Allen LOI, it will have substantial financial commitments
with respect thereto. No assurance can be given that the transactions
contemplated by the Allen LOI will be consummated or, if consummated,
successfully managed and/or developed by the Company. See "Risk Factors--Real
Estate Investment Considerations--Risks of Real Estate Acquisition and
Development" and "--Real Estate Financing Risks" and "Business and
Properties--The Allen Group Letter of Intent."

The Company makes quarterly distributions to stockholders from cash
available for distribution and, if necessary to satisfy distribution
requirements to maintain its status as a REIT, the Company may use borrowings
under its Credit Facility. All such distributions are at the discretion of the
Board of Directors. Amounts accumulated for distribution are invested by the
Company primarily in interest-bearing accounts and short-term, interest-
bearing securities, which are consistent with the Company's intention to
qualify for taxation 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.

In May 1997, the Company entered into its $150.0 million Credit Facility
with MGT. The Company recently received a commitment from the lender to
increase the amount available under the Credit Facility to $200.0 million. The
Credit Facility bears interest at a variable rate equal to either (a) LIBOR
plus 1.50% or (b) 0.25% plus a rate equal to the higher of (i) MGT's prime
rate then in effect or (ii) the federal funds rate plus 0.5%. The Credit
Facility matures in May 1999, subject to a one-year option to extend the term.
The Credit Facility is secured by certain of the Properties. In addition, in
connection with the IPO, the Operating Partnership obtained mortgage loans
totaling $96.0 million (the "Mortgage Loans") from MGT. The proceeds of the
Mortgage Loans principally were used to repay existing indebtedness on the
Properties contributed by the Kilroy Group in connection with the IPO. The
Mortgage Loans consist of the $84.0 Million Loan which is secured by certain
of the Properties and the SeaTac Loan. The $84.0 Million Loan matures on
February 1, 2022 and bears interest at 8.35%. After January 31, 2005 (the
"Reset Date"), the interest rate resets to the greater of 13.35% and the sum
of the yield of noncallable U.S. Treasury Securities maturing 15 years from
the Reset Date plus 5.0%. The SeaTac Loan matures on January 31, 1998 and
bears interest at LIBOR plus 1.50%. On August 13, 1997, the Company increased
the outstanding principal amount under the SeaTac Loan by $2.0 million to
$14.0 million.

The Company was adversely impacted in 1993 and 1994 by the decline in market
rental rates, higher vacancies and its higher leverage which prevented it from
meeting certain of its financial obligations. Bank notes relating to
properties, other than the SeaTac Office Center, aggregating $9.7 million and
$23.7 million were in default as of December 31, 1995 and 1994, respectively.
Past due interest relating to the notes was $2.9 million and $5.7 million as
of December 31, 1995 and 1994, respectively. In addition, property taxes of
$0.1 million, $0.5 million and $0.6 million were past due as of December 31,
1996, 1995 and 1994, respectively. In June 1996, the Company repaid the
principal of the bank notes relating to such properties, and the applicable
accrued interest, and all but $40,000 of the property taxes, with the proceeds
of a financing secured by certain of the Industrial Properties. With respect
to the SeaTac Office Center, a high vacancy rate in 1993 resulted in
insufficient cash flow to service the underlying debt on this Property. The
high vacancy rate continued and a note payable to an insurance company having
a principal balance of $20.2 million and accrued interest of $2.4 million, as
of December 31, 1996, was in default since October 1995. In October 1996, the
Company successfully negotiated a discounted payoff with the lender and the
ground lessor which provided for a payoff or purchase of the lender's note at
a discount on or before February 10, 1997 which was repaid with the net
proceeds of the IPO and borrowings under the SeaTac Loan. Bank notes relating
to the SeaTac Office Center aggregating $6.8 million were in default as of
December 31, 1995 and 1994. Past due interest relating to these notes was $2.1
million and $1.4 million as of December 31, 1995 and 1994, respectively. In
June 1996, the Company repaid the principal of the bank notes and the
applicable accrued interest relating to the SeaTac Office Center with the
proceeds of a financing secured by certain of the Industrial Properties.

The Company believes that it will have sufficient capital resources to
satisfy its obligations during its first year of operations which commenced on
January 31, 1997. The Company expects to meet certain of its long-term
liquidity requirements, including the repayment of long-term debt of $84.0
million (less scheduled principal repayments) in 2005, the repayment of debt
of $14.0 million in January 1998 and possible property acquisitions and
development, through long-term secured and unsecured borrowings, including the
Credit Facility, and the issuance of debt securities or additional equity
securities of the Company or, possibly in connection with acquisitions of land
or improved properties, the issuance of Units of the Operating Partnership.

The Phase I environmental assessments of the Properties have not revealed
any environmental liability that the Company believes would have a material
adverse effect on the Company's financial condition or results of operations
taken as a whole, nor is the Company aware of any such material environmental
liability. See "Risk Factors--Government Regulations--Environmental Matters"
and "Business and Properties--Government Regulations--Environmental Matters."

HISTORICAL CASH FLOWS

Historically, the Kilroy Group's principal sources of funding for operations
and capital expenditures were cash flow from operating activities and secured
debt financings. The Kilroy Group incurred net losses before equity in income
of subsidiaries, minority interest and extraordinary item in each of the last
five years through December 31, 1996. However, after adding back depreciation
and amortization, the Properties contributed by the Kilroy Group generated
positive net operating cash flows for each of the last four years through
December 31, 1996.

The Company's net cash from operating activities was $5.8 million for the
six months ended June 30, 1997 and 1996. There was an increase in income
before non-cash extraordinary gains of $7.5 million from a loss of $1.2
million in the six months ended June 30, 1996 to $6.3 million in the six
months ended June 30, 1997. This increase was used for other assets of $4.3
million, accrued interest of $3.0 million and the accrued cost of option buy
out and tenant improvements of $1.4 million. The Company's net cash from
operating activities decreased $4.6 million to $5.5 million during the year
ended December 31, 1996 compared with $10.1 million in the comparable 1995
period. The decrease was a result of the sale of air rights of $4.5 million in
1995, the option buy-out cost of $3.15 million in 1996, offset by an increase
in total rent of $1.0 million in 1996 and a decrease in interest expense of
$2.3 million in 1996. The Company's net cash from operating activities
increased $3.5 million from the year ended December 31, 1994 compared to the
same period in 1995, or from $6.6 million in 1994 to $10.1 million in 1995.
The increase was primarily due to the sale of air rights in 1995 of $4.5
million.

Net cash used in investing activities increased $236.2 million to $236.6
million for the six months ended June 30, 1997 from $0.4 million in the six
months ended June 30, 1996. The increase was due to the purchase of 25 acres
of land, 20 office buildings and 29 industrial buildings for an aggregate
acquisition cost of $218.7 million (net of $4.0 million paid in Units) and
additional tenant improvements and capital expenditures of $0.6 million. Net
cash used in investing activities increased $1.2 million to $2.4 million in
the year ended December 31, 1996 from $1.2 million in the 1995 period
primarily due to an increase in the number of new lease transactions and the
resulting increase in the level of tenant improvements. Net cash used in
investing activities decreased $0.6 million to $1.2 million for the year ended
December 31, 1995 from $1.8 million for 1994 due to a decrease in the number
of new lease transactions and the resulting decrease in the level of tenant
improvements.

Cash flows provided by financing activities totaled $265.1 million for the
six months ended June 30, 1997 compared to net cash used in financing
activities of $5.4 million during the first six months of 1996. The increase
in the six months ended June 30, 1997 is primarily attributable to net
proceeds from the IPO of $302.8 million, a net repayment of debt of $123.1
million and borrowings under the Credit Facility of $92.0 million compared to
net proceeds from debt of $3.5 million during the same period in 1996. In
addition, there were dividends of $3.7 million and loan costs of $3.2 million
and an increase in restricted cash of $5.7 million during the six months ended
June 30, 1997 compared to loan costs of $2.6 million in the same period in
1996. During the six months ended June 30, 1997, there was a contribution from
partners of $6.1 million, compared to a net distribution of $6.3 million
during the same period in 1996. Cash flows used in financing activities was
$3.4 million for the year ended December 31, 1996 consisting of net proceeds
from issuance of debt of $2.1 million, less $5.2 million in distributions to
partners. Cash flows used in financing activities increased $4.1 million to
$8.9 million for the year ended December 31, 1995 compared to net cash used in
financing activities of $4.8 million for the same period in 1994 as result of
net repayment of debt in the 1995 period compared to net borrowings in the
1994 period and a $4.6 million decrease in deemed distributions to partners.

FUNDS FROM OPERATIONS

Industry analysts generally consider Funds from Operations, as defined by
NAREIT, an alternative measure of performance of an equity REIT. Funds from
Operations is defined by NAREIT to mean net income (loss) before minority
interest of unitholders (determined 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
believes that in order to facilitate a clear understanding of the combined
historical operating results of the Company, Funds from Operations should be
examined in conjunction with net income (loss) as presented in the audited
Combined Financial Statements and selected financial data included elsewhere
in this Prospectus. 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 such other REITs. Funds from Operations should not be considered
as an alternative to net income (loss), as an indication of the Company's
performance or to cash flows as a measure of liquidity or the ability to pay
dividends or make distributions.

INFLATION

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

ADOPTION OF ACCOUNTING STANDARDS

Statement of Financial Accounting Standards No. 123, Accounting for Stock-
Based Compensation, is effective for transactions entered into in fiscal years
beginning after December 15, 1995. The Company plans to continue accounting
for stock-based employee compensation plans under APB Opinion No. 25,
Accounting for Stock Issued to Employees, and related interpretations. The
Company will present pro forma disclosures of net income and earnings per
share as if the fair value based method of accounting for stock-based
compensation had been elected, for all awards granted in the year ending
December 31, 1997 in its Annual Report on Form 10-K.

In February 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 128, Earnings Per Share. This statement
establishes standards for computing and presenting earnings per share ("EPS")
and applies to entities with publicly held common stock or potential common
stock. This statement simplifies the standards for computing EPS previously
found in APB Opinion No. 15, Earnings per Share, and makes them comparable to
international EPS standards. This statement is effective for financial
statements issued for periods ending after December 15, 1997, including
interim periods. The Company has not yet analyzed the impact of adopting this
statement.

In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 130 Reporting for Comprehensive Income and
No. 131, Disclosures about Segments of an Enterprise and Related Information.
These statements are effective for financial statements issued for periods
beginning after December 15, 1997. The Company has not yet analyzed the impact
of adopting these statements.

BUSINESS AND PROPERTIES

GENERAL

The Company's portfolio of properties includes 33 office buildings
encompassing an aggregate of approximately 2.9 million rentable square feet
and 52 industrial buildings encompassing an aggregate of approximately 3.6
million rentable square feet. All but eight of the Properties are located in
prime Southern California suburban submarkets (including a complex of three
Office buildings located in El Segundo, adjacent to LAX, presently the
nation's second largest air-cargo port, and a complex of five office buildings
located adjacent to the Long Beach Airport). The SeaTac Office Center is
comprised of three office buildings located adjacent to the Seattle-Tacoma
International Airport. The weighted average age of the Office Properties is
approximately 14 years and the weighted average age of the Industrial
Properties is approximately 18 years. As of June 30, 1997, the Office
Properties were approximately 88.1% leased to 166 tenants (95.3% leased giving
effect to the Boeing Lease), and the Industrial Properties were approximately
97.4% leased to 166 tenants. The Company's major tenants include, among
others, Hughes Space & Communications, a tenant since 1984, which is engaged
in high-technology commercial activities including satellite development and
related applications such as DirecTV, and other major tenants such as Sony
Music Entertainment, Boeing (giving effect to the Boeing Lease), M/R Systems,
Mattel, Inc., Northwest Airlines, Inc. and Caltrans.

Since the completion of its IPO, the Company acquired or presently expects
to complete the acquisition of an aggregate of 19 suburban office buildings
encompassing approximately 900,000 rentable square feet for an aggregate
acquisition cost (including expenses, closing costs and anticipated capital
expenditures) of approximately $107.9 million, and 40 industrial buildings
encompassing approximately 2.2 million rentable square feet for an aggregate
acquisition cost (including expenses, closing costs and anticipated capital
expenditures) of approximately $147.8 million. For one Acquired Property, the
acquisition cost was paid, in part, with the issuance of 165,102 limited
partnership Units. The issuance of the Units permits sellers of properties to
defer the recognition of all or part of the taxable gain, if any, on the
disposition of such properties. All but four of the Acquired and Pending
Properties are located in Southern California. Of the Acquired and Pending
Properties, 28 buildings are located in submarkets in which the Company
already owned office or industrial property at the completion of the IPO, and
31 buildings are located in new submarkets within Los Angeles County, Northern
Orange County, Southern Orange County, Western San Bernardino County, Northern
San Diego County, Santa Clara County and Placer County. Management believes
that each of these new submarkets offers significant growth opportunities. See
"--The Company's Principal Southern California Submarkets." As a result of
these acquisitions, the Company's aggregate rentable square feet of office and
industrial space increased by approximately 43.0% and 166.0%, respectively. In
addition, the Company is currently in active negotiations to purchase eight
Pipeline Properties, all of which are located in Southern California, for an
aggregate acquisition cost of $68.0 million, including the assumption of $14.0
million of mortgage indebtedness. No assurance can be given that the Pending
Acquisitions or the acquisition of the Pipeline Properties will be
consummated. See "Risk Factors--Real Estate Investment Considerations--Risks
of Real Estate Acquisitions and Development" and "--Acquired Properties" and
"--Pending Acquisitions."

The Company currently owns or has exclusive rights to develop approximately
60 acres of developable land (net of the acreage required for streets),
including (i) ten acres in Brea, California, (ii) 15 acres in Foothill Ranch
in Orange County, California, (iii) two and one-half acres in Anaheim,
California, (iv) three and one-half acres in Irvine, California, (v) five
acres in Camarillo, California, and (vi) 24 acres at Kilroy Airport Center
Long Beach. Management believes that it can build up to 1.6 million rentable
square feet on the Development Properties, subject to required entitlements
and other governmental approvals, of which approximately 500,000 rentable
square feet is planned for development beginning in 1997. The Company may
engage in the development of office or industrial properties when market
conditions support a favorable risk-adjusted rate of return on such
development. No assurance can be given that the Company will commence any
development, or that, if commenced, any such development will be completed.
See "Risk Factors--Real Estate Investment Considerations--Risks of Real Estate
Acquisition and Development" and "--Development, Leasing and Management
Activities--Kilroy Airport Center, Long Beach."

In general, the Office Properties are leased to tenants on a full service
basis, with the landlord 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. Substantially all
of the leases for the Industrial Properties are written on a triple net basis,
with tenants paying their proportionate share of real estate taxes, operating
costs and utility costs.

Existing Office Properties

The following table sets forth certain information (on a per rentable square
foot basis) regarding leasing activity at the Office Properties owned by the
Company upon completion of its IPO (the "Existing Office Properties") since
January 1, 1992 (based upon an average of all lease transactions during the
respective periods). As presented in the table below, for the six-month period
ended June 30, 1997, the Company entered into six office property lease
transactions for an aggregate 32,796 rentable square feet with a weighted
average initial annual base rent per square foot of $15.70. Of this amount,
over 27,000 rentable square feet was leased to one tenant at the SeaTac Office
Center at an average rent per square foot of approximately $13.88. The
remaining approximately 6,000 rentable square feet was leased at various
properties at an average rent per square foot of $24.80.

(1) Represents the year built or the date of the most recent substantial
renovation. For Properties with multiple buildings, the year built refers
to the earliest date with respect to such buildings.
(2) Based on all leases at the respective Properties in effect as of December
31, 1996.
(3) Total base rent for the year ended December 31, 1996, determined in
accordance with GAAP. All leases at the Industrial Properties are written
on a triple net basis. Unless otherwise indicated, all leases at the
Office Properties are written on a full service gross basis, with the
landlord obligated to pay the tenant's proportionate share of taxes,
insurance and operating expenses up to the amount incurred during the
Base Year or a negotiated amount approximating the Expense Stop. Each
tenant pays its pro rata share of increases in expenses above the Base
Year or Expense Stop.

(footnotes continued on next page)

<PAGE>

(4) Aggregate base rent received over the respective lease term from all
lease transactions in effect at December 31, 1996 minus all tenant
improvements, leasing commissions and other concessions for all such
leases, paid or payable by the Company, divided by the terms in months
for such leases, multiplied by 12. Tenant improvements, leasing
commissions and other concessions are estimated using the same
methodology used to calculate effective rent for the Properties as a
whole in the charts set forth under the caption "--General."
(5) The percentage of 1996 total base rent is calculated as the base rent of
the respective Property for the year ended December 31, 1996 divided by
the combined base rent for all of the Properties (including the Acquired
Properties and the Pending Acquisitions) for the year ended December 31,
1996.
(6) Base rent for the year ended December 31, 1996 divided by rentable square
feet leased at December 31, 1996.
(7) Effective rent at December 31, 1996 divided by rentable square feet
leased at December 31, 1996.
(8) Based on all leases at the respective Properties dated on or before June
30, 1997.
(9) Excludes office space leased by the Company.
(10) For this Property, leases with Hughes Space & Communications, for
approximately 96,000 rentable square feet, and with SDRC Software
Products Marketing Division, Inc., for approximately 6,800 rentable
square feet, are written on a full service gross basis except that there
is no Expense Stop.
(11) For this Property, the lease with Hughes Space & Communications is
written on a modified full service gross basis under which Hughes Space &
Communications pays for all utilities and other internal maintenance
costs with respect to the leased space and, in addition, pays its pro
rata share of real estate taxes, insurance, and certain other expenses
including common area expenses.
(12) For this Property, leases with Hughes Space & Communications for
approximately 103,000 rentable square feet are written on a full service
gross basis except that there is no Expense Stop.
(13) For this Property, the lease is written on a triple net basis.
(14) The data does not reflect the lease of 211,000 rentable square feet of
office space with Boeing at the SeaTac Office Center, entered into as of
June 20, 1997 which provides for occupancy by December 31, 1997. See "--
Office Properties--Kilroy Airport Center, Sea Tac."
(15) This Industrial Property was vacant until April 1996. The tenant began
paying rent in mid-October 1996 at an annual rate of $4.40 per rentable
square foot.
(16) The tenant subleased this Industrial Property on May 15, 1996 to RGB
Systems, Inc. (doing business as Extron Electronics), the tenant of the
Property located at 1230 S. Lewis Street, Anaheim, California, which is
adjacent to this Industrial Property. The sublease is at an amount less
than the current lease rate, and the tenant is paying the difference
between the current lease rate and the sublease rate. The lease and the
sublease terminate in April 1998. Extron Electronics has executed a lease
for this space from May 1998 through April 2005 at the current lease
rate. Extron Electronics continues to occupy the space located at 1230 S.
Lewis Street.
(17) This Industrial Property was originally designed for multi-tenant use and
currently is leased to a single tenant and utilized as an indoor multi-
vendor retail marketplace.
(18) The leases for this Industrial Property are written on a modified triple
net basis, with the tenants responsible for estimated allocated common
area expenses.
(19) As of the date of this Prospectus, the Company has not completed the
acquisition of this Property.
(20) The Brea Industrial Properties consist of 660 Puente Street, 1050 West
Central, 1150 West Central, 950 West Central, 895 Beacon Street, 955
Beacon Street and 1125 Beacon Street.
(21) The Garden Grove Industrial Properties consist of 12442 Knott Avenue,
7091 Belgrave Avenue, 12311-21 Industry Street, 12241-71 Industry Street,
7261 Lampson Avenue and 12472 Edison Way.
(22) Financial information for the year ended December 31, 1996, for 9401 and
9451 Toledo Way, Irvine, California is not available because the Property
was 100.0% owner-occupied. Concurrent with the Company's acquisition of
the Property, a lease was signed by the former owner for a continued
100.0% occupancy of the Property.
(23) Subsequent to June 30, 1997, this tenant terminated its lease and the
portion of the office space previously occupied by such tenant is now
available for lease.
(24) This Property is managed by third-party managers. See "--Development,
Leasing and Management Activities."

OFFICE PROPERTIES

All but four of the office buildings are Class A office buildings. Each of
the Kilroy LAX, Kilroy Long Beach and SeaTac Office Center (each as defined)
Office Properties was designed and developed to above-standard specifications
to accommodate the long-term needs of tenants and include features such as
extra-floor loading capacity and extra-high ceilings. Each of the Kilroy LAX,
Kilroy Long Beach and SeaTac Office Properties also was designed with an
emphasis on long-term operating efficiency and tenant comfort and includes
above-standard climate controls, on-site management and security, covered
parking, heliports and retail services, all in professionally landscaped
environments. In addition, each of the Kilroy LAX and Kilroy Long Beach Office
Properties offers tenants redundant telecommunications capability and utility
leads. The Office Properties range in size up to 12 stories and are easily
accessible from major highways and the substantial majority are easily
accessible from major airports. Management believes that the location, quality
of construction and amenities at the complexes as well as the Company's
reputation for providing a high level of tenant service have enabled the
Company to attract and retain a national tenant base.

Kilroy LAX

General. The Company developed, owns, leases and manages three office
buildings at Kilroy Airport Center at El Segundo ("Kilroy LAX"), a Class A
high-rise, multi-tenant corporate office complex situated in what the Company
considers to be the premier location in El Segundo immediately adjacent to
LAX, the new light rail system servicing Los Angeles County and the new I-105
Freeway with a freeway off-ramp and freeway on-ramp providing immediate access
to and from the project's parking facilities. Kilroy LAX was built in 1983 to
high quality specifications to address the anticipated demands of the
submarket's aerospace and high technology tenants. The Company believes Kilroy
LAX has the premier location in the El Segundo office submarket for a number
of reasons, including: (i) unobstructed views of LAX, West Los Angeles and
downtown Los Angeles; (ii) excellent access to LAX, the new I-105 Freeway and
the new light rail system; (iii) close proximity to corporate office users
including Hughes Space & Communications and its satellite manufacturing
facility, and other related enterprises such as DirecTV; and (iv) for tenants
with their names on the Property, visibility to freeway and airline travelers.

The complex is comprised of two 12-story towers and a 13-level parking
structure with two floors of office space on top, encompassing an aggregate of
approximately 701,000 rentable square feet, of which 98.2% was leased as of
June 30, 1997. Management believes because of its premier location and other
high quality features, Kilroy LAX continues to attract long-term major
corporate tenants at rates above those offered by other facilities in the El
Segundo and neighboring submarkets. The occupancy rates for Kilroy LAX as of
the years ended December 31, 1993 through 1996, and the six-month period ended
June 30, 1997, were 90.8%, 91.6%, 92.1%, 94.4% and 98.2%, respectively.

Major tenants of the facility include Hughes Space & Communications (the
Company's largest tenant), the Federal Aviation Administration and Realtime
Associates. Hughes Space & Communications has been a tenant at Kilroy LAX
since its opening and, over the past five years, has consolidated operations
into its owned facilities in El Segundo (which includes its satellite
manufacturing facility) and into leased facilities at Kilroy LAX which also
serves as its headquarters. In addition, Hughes Space & Communications has
invested substantial amounts in tenant improvements, including approximately
$3.3 million during the year ended December 31, 1994 and $23.5 million since
1984, and repeatedly has renewed leases at the facilities, including one lease
for approximately 103,000 rentable square feet which has been renewed twice.
Hughes Space and Communications is a major employer and owner of technical
facilities in El Segundo, including facilities for the development of
satellite technology and its applications, such as DirecTV.

2240 E. Imperial Highway, El Segundo. The Office Property located at 2240 E.
Imperial Highway had an occupancy rate of 100.0% for each of the years ended
December 31, 1992 through 1996 and the six-month period ended June 30, 1997.
The Office Property is presently 100.0% leased pursuant to three leases. One
lease for 103,035 rentable square feet (representing 86.6% of the total leased
rentable square feet in the Property), expires in 1999 and has annual base
rent of $1,085,716 per year, or $10.54 per rentable square foot. The other two
leases are for an aggregate of 15,898 rentable square feet (representing 13.4%
of the total leased rentable square feet in the Property), expire in 2001 and
have aggregate annual base rent of $206,670, or $13.00 per rentable square
foot. As of June 30, 1997, Hughes Space & Communications occupied
approximately 96.3% of the Property's rentable square feet under two leases.
Under the principal lease for this space, Hughes Space & Communications
commenced occupancy of 103,035 rentable square feet on August 11, 1986 and
renewed the lease on February 1, 1989 and again on June 1, 1994. In connection
with the latter renewal, Hughes made a one time payment of $4,000,000 to the
Company in consideration of a lease amendment to relieve Hughes Space &
Communications of the obligation to remove certain tenant improvements upon
termination of the lease. The current lease term under this lease expires on
January 31, 1999, subject to a five-year option to renew at fair market value,
but not less than $15.84 per annum per rentable square foot, on a triple net
basis. Hughes Space & Communications also leases 11,556 rentable square feet
(along with the 96,133 rentable square feet located at 2250 E. Imperial
Highway) under a second lease which expires October 31, 2001, at an annualized
triple net base rental rate of $14.04 and, for the first year of the lease
term, the tenant's allocable share of operating costs shall not exceed $7.32
per rentable square foot. The lease also is subject to a five-year option to
renew at fair market value, adjusted bi-annually for CPI adjusted increases in
base rent. The total annual rental income per rentable square foot for the
years ended December 31, 1992 through December 31, 1996 was $24.42, $25.22,
$17.15, $11.83 and $11.70, respectively.

The Company's tax basis in this Property for federal income tax purposes as
of December 31, 1996 was approximately $2.0 million (net of accumulated
depreciation and reductions in depreciable basis), and was fully depreciated.
The Property was depreciated using the modified accelerated cost recovery
system straight-line method, based on an estimated useful life ranging from 31
1/2 years to 39 years, depending upon the date of certain capitalized
improvements to the Property. For the 12-month period ending December 31,
1996, the Company was assessed property taxes on this Property at an effective
annual rate of approximately 1.0%. Property taxes on this Property for the 12-
month period ending December 31, 1996 totaled approximately $128,411.
Management does not believe that any capital improvements made during 1997, if
any, should result in an increase in annual property taxes, although the
contribution of the Property to the Operating Partnership in connection the
Formation Transactions will cause this Property to be reassessed to its fair
market value at January 31, 1997.

2250 E. Imperial Highway, El Segundo. The information presented below gives
pro forma effect to the November 1996 extension of the tenant lease with
Hughes Space & Communications with respect to this Office Property as if such
lease renewal had occurred on January 1, 1996.

1997, respectively. As of June 30, 1997, Hughes Space & Communications
occupied 42.5% of the Property's rentable square feet. The Property's other
tenants include companies engaged in the communications, technology,
transportation and healthcare industries. Hughes Space & Communications

entered into an agreement to renew this space (along with the 11,556 rentable
square feet located at 2240 E. Imperial Highway) through October 31, 2001, at
a triple net annual base rental rate of $14.04 per square foot and, for the
first year of the lease term, the tenant's allocable share of operating costs
shall not exceed $7.32 per rentable square foot. The lease also is subject to
a five-year option to renew at fair market value, adjusted bi-annually for CPI
increases in base rent. The total annual rental income per rentable square
foot for the years ended December 31, 1992 through December 31, 1996 was
$18.73, $19.62, $18.89, $18.86 and $18.74, respectively. The following table

which 82.0%

89
<PAGE>

was leased as of June 30, 1997 (giving effect to the Boeing Lease). Current
zoning permits up to an additional 500,000 rentable square feet of
development. As of June 30, 1997, the SeaTac Office Center had approximately
96,000 rentable square feet of available office space. Major tenants include
Boeing, First Nationwide Mortgage Corporation, Lynden, Inc., National
Chemsearch, Northwest Airlines, Inc., Rayonier, Inc., Seattle-First National
Bank and Transamerica Financial Services, Inc.

In June 1997, Boeing signed a lease for 211,000 rentable square feet. The
lease is for a term of seven years and includes an option to cancel after five
years. Under the terms of the lease, Boeing may occupy the office space upon
completion of certain tenant improvements but in any event not later January
1, 1998. The lease has a net effective rent per square foot of $7.36.

The SeaTac Office Center is situated on an approximately 17-acre site
subject to two long-term ground leases and an airspace lease. The initial term
of the ground leases runs through December 31, 2032, and may be extended for
an additional period of thirty years. Except with respect to one of the ground
leases at the SeaTac Office Center, payments under the ground leases are
subject to adjustment for increases in the CPI every five years. Payments
under the airspace lease are made monthly. Aggregate payments under the two
ground leases and the airspace lease for the year ended December 31, 1996
totaled approximately $309,300. As of August 1997, the SeaTac Office Center
properties were encumbered by a first mortgage loan having an outstanding
principal balance of $14.0 million. See "Description of Indebtedness--The
SeaTac Loan."

INDUSTRIAL PROPERTIES

Like the Office Properties, the Industrial Properties developed by the
Company were designed and developed to provide above-standard quality and meet
the long-term needs of tenants. The Company was among the first Southern
California developers to air-condition its Industrial Properties, increasing
each facility's multidimensional use while providing environments for
increased tenant operating efficiency and comfort. The Industrial Properties
developed by the Company were designed for multi-tenant operations and can be
configured for such use. The Industrial Properties, all but one of which are
located in Southern California, are primarily comprised of single-story, tilt-
up concrete buildings ranging in size up to 277,000 rentable square feet.

Substantially all of the Industrial Property leases are written on a triple
net basis with initial terms of three to eleven years and options to renew for
up to an additional five-year period at the then current fair market value.
The leases generally provide for rent increases based on the applicable
regional CPI or contain specific contractual increases. Except for the lease
at 2260 E. El Segundo where the sole tenant has a right of first offer, the
leases do not contain purchase options.

ACQUIRED PROPERTIES

The Company completed a series of transactions in which it acquired
properties comprising an aggregate of approximately 2.6 million rentable
square feet. The Acquired Properties were financed from the net proceeds of
the IPO, borrowings under the Credit Facility and working capital, and, in the
case of one Acquired Property, in part, with limited partnership Units.

Sony Complex. Located at 2100 Colorado Avenue, Santa Monica, California, the
Sony Complex was completed in 1992 on a build-to-suit basis for Sony Music
Entertainment, Inc. ("Sony Music"). The project consists of two, three-story
buildings and one, two-story building, for an aggregate of approximately
94,844 rentable square feet. As of June 30, 1997, these Class A office
buildings were 100.0% leased to Sony Music. The complex has been designed with
a campus-like setting and extensive build-out which is a preference for many
of the entertainment-related firms located in the Santa Monica submarket. The
1.7 acre site is located one-quarter mile north of Interstate 10 and includes
a 230-space subterranean parking structure, an extensive water feature and a
full-service cafe. Since completion in 1992 through the date of purchase by
the Company, the building was 100.0% owner occupied. The lease for 94,844
rentable square feet with Sony Music provides for base rent of $2.7 million
per year, or $28.46 per rentable square foot, and expires on December 31,
2008, subject to two successive five year renewal options.

depreciation rate for this Property under the modified accelerated cost
recovery system is 2.5%. Property taxes on this Property for the 12-month
period year ending December 31, 1996 totaled $290,900. Management does not
believe that capital improvements made during 1997, if any, should result in
an increase in annual property taxes, although the purchase of this Property
will cause it to be reassessed to its purchase price as of the purchase date.

rentable square foot for the 12 months ended December 31, 1992 through 1996
was $14.66, $15.24, $10.50, $8.24 and $14.36. The decreases in average rent
per rentable square foot in 1994 and 1995 are attributable to contractual rent
concessions applicable to such years pursuant to the lease agreement.

THE ALLEN GROUP LETTER OF INTENT

On July 30, the Company signed a non-binding letter of intent (the "Allen
LOI") with The Allen Group ("Allen") to acquire the principal assets of Allen
which include approximately 1.7 million rentable square feet of completed and
under construction office and industrial properties, and developable land,
located primarily in Northern San Diego County. If consummated, the Company
would purchase the assets in phases over the next several years for a total
investment currently estimated to exceed $300 million. Allen is a privately
held, San Diego-based real estate investment and development company. Upon the
closing of the first phase, Richard S. Allen, managing partner of Allen, would
join the Company's Board of Directors and two key members of Allen's
management team would join the Company as Executive Vice Presidents.

If completed, the transaction would enhance the Company's position as a
leading owner of office and industrial property in Southern California and
extend the Company's presence into the attractive Northern San Diego County
market. The acquisition also would provide the Company with: (i) a portfolio
of recently constructed office and industrial properties located in key
submarkets of North San Diego County, (ii) an acquisition pipeline of
properties which are under construction or for which construction is presently
expected to be completed by September 1998, (iii) a pipeline of land available
for future development, and (iv) enhanced development capabilities with the
addition of certain experienced executives of Allen.

The proposed transaction, which is subject to the completion of due
diligence and the negotiation of final documentation, could close as early as
the fourth quarter of 1997. If consummated, the Company would purchase in the
first phase two completed office and four completed industrial properties
containing a total of approximately 686,000 rentable square feet. These
properties have all been constructed since 1993 and are 100% leased on a
triple net basis.

In the second phase, the Company would purchase, upon completion of
construction (which is expected to occur before September 1998), four
office/research & development and two industrial properties containing a total
of approximately 684,000 square feet. Five of these properties are under
construction and one is expected to be under construction by the end of 1997.
These properties are 100% leased on a triple net basis.

In addition, the Company would purchase three office properties and one
industrial property that have a total of approximately 360,000 rentable square
feet over the next three years as they are completed and leased-up. Two of
these properties are completed and are in the lease-up stage and two of the
properties are to-be-developed.

The total purchase price for the completed, under construction and to-be-
leased properties is currently estimated to be approximately $200 million, $85
million of which could be invested by the end of 1997. The Company would pay
for the properties with a combination of cash, assumed debt and the issuance
of up to four million limited partnership Units. Nine of the properties are
located in San Diego County and seven are located in other areas of California
and Nevada.

The Allen LOI further provides that the Company would also purchase at fair
market value a 50% managing interest in one or more limited liability
companies that would own entitled and permitted developable land in San Diego
County. The remaining 50% non-managing interest would be owned by Allen. The
Company would acquire its interest in the limited liability companies after
completion of all entitlement, and infrastructure costs. If all of the land is
acquired, it is currently estimated it could be developed into one million
rentable square feet of office and industrial space and give the Company the
opportunity to control development of over $100 million of office and
industrial property with minimal carrying costs. The Services Company would
serve as the construction manager for future development on this land. The
Company would have the option to purchase the Allen-owned portion of any of
the properties before construction or after construction and lease-up.

94
<PAGE>

In addition to Richard S. Allen joining the Company's Board of Directors
(assuming consummation of the transaction), Steven L. Black and T. Patrick
Smith would join the Company as Executive Vice Presidents. Prior to forming
the real estate company in 1990, Richard S. Allen was a principal in the
family-owned Imperial Cup Company. Steven L. Black, currently a partner of The
Allen Group, is a veteran of the real estate industry with a 16-year history
in west coast commercial real estate. T. Patrick Smith, also a partner of The
Allen Group, was previously president of Irvine Apartment Communities, a
publicly-traded REIT, and, before that, was a division president with The
Irvine Company.

No assurance can be given that any of the transactions contemplated by the
Allen LOI will be consummated or, if consummated, successfully managed and/or
developed by the Company. In addition, if the Company enters into the
transactions contemplated by the Allen LOI, it will have substantial financial
commitments with respect thereto. See "Risk Factors--Real Estate Investment
Considerations--Risks of Real Estate Acquisition and Development," "--Real
Estate Financing Risks" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Liquidity and Capital Resources."

OPTION PROPERTIES

General. The Company holds options to acquire (i) parcels comprising an
aggregate of approximately 18 acres located at Calabasas Park Centre, in
Calabasas, California and (ii) a three-building office complex located on
North Sepulveda Boulevard in El Segundo, California (the "Sepulveda Boulevard
Office Complex") at the respective purchase price for each of the properties
as discussed below. Each Option Property is currently owned by a partnership
beneficially owned and controlled by John B. Kilroy, Sr. and John B. Kilroy,
Jr. The Sepulveda Boulevard Office Complex was developed and is leased and
managed by the Kilroy Group. The option for Calabasas Park Centre is
exercisable on or before January 31, 1998. The option for the Sepulveda
Boulevard Office Complex is exercisable on or before January 31, 2004. The
acquisition cost for each of the properties is payable in cash; provided,
however, that if the option for the Sepulveda Boulevard Office Complex is
exercised after January 31, 1998, the acquisition cost will be payable in cash
or limited partnership Units at the election of the seller. The Company
intends to account for acquisitions of Option Properties, if any, using the
purchase accounting method.

In the event that the owner of one of the Option Properties receives an
offer from a third party for the master lease or purchase of such property,
such owner may give notice to the Company, which notice shall include the
proposed purchase price, leasing terms and/or other economic terms of the
proposed transfer or lease of such property. The Company shall then have 60
days to give notice of its election to acquire or lease such property at the
lower of the applicable option price or the proposed purchase price or lease
terms. In the event that the Company does not give such notice, the option to
acquire such property shall be suspended and the owner may proceed with the
sale or lease of such parcel pursuant to the terms of such offer, provided
that the economic terms may be up to 5% below that described in such notice;
provided, however, that with respect to any sale of the approximately 18 acres
located at Calabasas Park Centre discussed below, the Company shall have the
right to acquire at the option price the owners' rights and related monetary
obligations under the respective sales agreement. In the event the owners of
such property (i) have not entered into a letter of intent for the sale or
lease of such property within 180 days following the notice to the Company
referenced above, or (ii) have not completed the sale of the respective
property within 270 days following such notice, then the Company's option with
respect to such property shall be reinstated, up to the expiration date of the
option. The Company's options are subject to any arrangements entered into by
the Kilroy Group in connection with any financing, recapitalization or leasing
of the properties including, without limitation, any rights of the lender(s)
with respect to such properties with respect to a transfer pursuant to the
applicable option. In addition, the Sepulveda Boulevard Office Complex will be
managed by the Operating Partnership pursuant to a management agreement on
market terms.

Calabasas Park Centre. Kilroy Calabasas Associates, a limited partnership,
beneficially owned 49.0% by John B. Kilroy, Sr. and 51.0% by John B. Kilroy,
Jr., and controlled by both of them, owns Calabasas Park Centre, an
approximately 66-acre site (representing approximately 45 developable acres,
net of acreage required for streets and contractually required open areas) in
the City of Calabasas located immediately west of the San Fernando Valley,
which is presently entitled for over one million rentable square feet of
office, retail and hotel development. The property has substantially all
significant infrastructure improvements in place. Kilroy Calabasas Associates
is actively marketing for sale various parcels totaling approximately 27 acres
for neighborhood retail and hotel development, of which approximately 1.7
acres is proposed to be dedicated to the City of Calabasas for civic use.
Kilroy Calabasas Associates has received offers with respect to certain
parcels and is pursuing such offers in the ordinary course of business,
although there is no assurance that any such transactions will be completed in
the near term. John B. Kilroy, Sr. and John B. Kilroy, Jr. each spend an
immaterial amount of time in connection with any entitlement, marketing and
sales of parcels of Calabasas Park Centre. The remaining approximately 18
acres for which the Company has been granted an option is entitled for over
500,000 rentable square feet for office, hotel and limited retail use. Because
of the uncertainty that such 18 acres will be used primarily as office space,
this property is not appropriate for inclusion in the Company's portfolio at
this time. In addition, both John B. Kilroy, Sr. and John B. Kilroy, Jr. have
agreed not to sell any of the parcels at Calabasas Park Centre to a real
estate investment trust with an existing portfolio of office or industrial
properties unless first offered to the Company on the same economic terms. See
"Policies with Respect to Certain Activities--Conflicts of Interest Policies--
Noncompetition Agreements."

Pursuant to the terms of the applicable option agreement, the purchase price
for the parcels located at Calabasas Park Centre will be equal to the total
accumulated costs, as of the date such option is exercised, in connection with
acquisition of rights with respect to, and the entitlement and development of
such property, including, without limitation, property taxes, predevelopment
and entitlement costs and fees, and related bond financing costs.

North Sepulveda Boulevard, El Segundo. The Kilroy Group developed and
operates the Sepulveda Boulevard Office Complex which consists of a three-
building office complex located on an over 3.5-acre parcel in El Segundo,
California, adjacent to LAX. The complex is comprised of an 11-story office
building (constructed in 1972), an eight-story office building (constructed in
1962) and a seven-level parking structure with retail space on the ground
floor (constructed in 1972), encompassing an aggregate of approximately
360,000 rentable square feet of office space and approximately 5,600 rentable
square feet of retail space. The properties have convenient access to LAX and
the I-105 Freeway. As of June 30, 1997, the office space was 100% leased to
Hughes Space & Communications at an average annual triple net base rent per
rentable square foot of $21.06, subject to a lease scheduled to expire on
February 28, 1998. It is expected that Hughes Space & Communications will
enter into a new lease for only approximately 68% of the rentable square feet
at the complex. The property is owned by Kilroy Airport Imperial Co., a
limited partnership, beneficially owned by John B. Kilroy, Sr. and by John B.
Kilroy, Jr. (who have an approximately 65.1% interest and an 18.2% interest,
respectively), and controlled by both of them. In addition, each of John B.
Kilroy, Sr.'s four other children have an approximately 4.2% interest in the
limited partnership. Each of Messrs. Kilroy spend an immaterial amount of time
in connection with the management of the property.

Pursuant to the terms of the applicable Option Agreement, the purchase price
for the Sepulveda Boulevard Office Complex is equal to the sum of (i) the then
outstanding mortgage indebtedness secured by the respective properties, plus
(ii) $1, plus (iii) the aggregate amount of capital contributed by the
beneficial owners of the property, net of actual cash distributions
distributed in respect of such beneficial owners, during the period beginning
on January 31, 1997 and ending on the date of exercise of the option, plus
(iv) an annualized return of 8.0% on the amount in excess of $5.0 million, if
any, as determined pursuant to clause (iii) preceding. The Company's option to
purchase the Sepulveda Boulevard Office Complex is subject to a right of first
offer held by Hughes Space & Communications.

DEVELOPMENT, LEASING AND MANAGEMENT ACTIVITIES

Since 1947, the Company and its predecessors have developed millions of
rentable square feet of office and industrial space, including high technology
facilities, primarily located in Southern California, for its own portfolio
and for third parties. Development activities include site selection, land
entitlement, project design and construction, build-to-suit activities and
tenant renovations. The Company has successfully developed numerous
sophisticated development projects for some of the nation's most prominent
corporations both in Southern California and around the country. The Company's
extensive experience has enabled it to form key alliances with major corporate
tenants, municipalities and landowners in Southern California. The Company's
relationships with tenants and users has enabled it to act as a developer of
various projects, and, in the case of Kilroy Airport Center Long Beach, to
develop the land for its own account when such development results in a
favorable risk-adjusted return on investment.

At the time of the IPO, the Company managed substantially all of its
Properties. As a result of the purchase of the Acquired Properties, the
Company currently manages 55 of its 85 buildings. The Company intends to take
over the management of its Southern California buildings currently managed by
third parties within the next 12 months. In addition, the Operating
Partnership provides building management services with respect to the Option
Properties. The Company actively engages in all aspects of the operations of
the properties it manages, including negotiating all leasing transactions. At
the 30 buildings where the Company does not perform management functions, the
Company hires third-party property managers to supervise day-to-day operations
while the Company actively monitors all management activities and is actively
engaged in the negotiation of all lease transactions. The Services Company
provides development services for the Company and for the Option Properties,
at market rates.

The Company currently owns or has exclusive rights to develop approximately
60 acres of developable land (net of the acreage required for streets),
including (i) ten acres in Brea, California, (ii) 15 acres in Foothill Ranch
in Orange County, California, (iii) two and one-half acres in Anaheim,
California, (iv) three and one-half acres in Irvine, California, (v) five
acres in Camarillo, California and (vi) 24 acres at Kilroy Airport Center Long
Beach. Management believes that it can build up to 1.6 million rentable square
feet on the Development Properties, subject to required entitlements and other
governmental approvals, of which approximately 500,000 rentable square feet is
planned for development beginning in 1997. The Company may engage in the
development of office or industrial properties when market conditions support
a favorable risk-adjusted rate of return on such development. No assurance can
be given that the Company will commence any development, or that, if
commenced, any such development will be completed. See "Risk Factors--Real
Estate Investment Considerations--Risks of Real Estate Acquisition and
Development."

The Company presently plans to develop an aggregate of up to 1.6 million
rentable square feet of office or industrial space on the Development
Properties, subject to required entitlements. Of this amount, the Company
plans to commence development of 500,000 rentable square feet of industrial
space in 1997 at a total budgeted cost of $25.0 million. No assurance can be
given that the Company will commence such development, or that, if commenced,
such development will be completed. See "Risk Factors--Real Estate Investment
Considerations--Risks of Real Estate Acquisition and Development."

The following is a description of the Development Properties as presently
contemplated.

Kilroy Airport Center Long Beach. In conjunction with the Company's role as
master ground lessee of Kilroy Airport Center Long Beach, the Company manages
all ongoing leasing and development activities for the four-phase,
approximately 53-acre office and retail development project, including sole
development rights to the approximately 24 remaining developable acres. To
date the Company has developed Phases I and II. See "--Office Properties--
Kilroy Airport Center, Long Beach." Current development activities are focused
on Phase III of the project ("Kilroy Long Beach Phase III") which is expected
to be developed and owned by the Company. Kilroy Airport Center Long Beach
also is planned to include Phase IV ("Kilroy Long Beach Phase IV"), which is
expected to be developed and owned by the Company. Kilroy Long Beach Phase IV
presently is contemplated to include an aggregate of up to 550,000 rentable
square feet of office and retail space including high quality retail and
specialty shops, sit-down and convenience restaurants and, subject to site-
plan approval by the City of Long Beach, a multitheater and virtual reality
entertainment center. Development of Kilroy Long Beach Phase IV is subject to
substantial predevelopment leasing activity and, therefore, the timing for the
commencement of development is uncertain.

To date the Company has invested approximately $8.8 million in
infrastructure improvements which are in place for Kilroy Long Beach Phases
III and IV and has available an additional approximately $1.4 million of
revenue bond proceeds held by the City of Long Beach which the Company
believes is sufficient to provide for further traffic mitigation improvements,
if any, which may be required by the city in connection with the future
development. Because of the over 900,000 aggregate rentable square feet
entitled at Kilroy Long Beach Phases III and IV, and the significant
infrastructure improvements already in place, the Company believes that Kilroy
Airport Center Long Beach offers substantial opportunity for tenant expansion
from a location servicing both Los Angeles and Orange Counties. See "--Office
Properties--Kilroy Airport Center, Long Beach."

THE COMPANY'S PRINCIPAL SOUTHERN CALIFORNIA SUBMARKETS*

The Company believes that Los Angeles, Orange and Ventura Counties have been
and will continue to be excellent markets in which to own and operate Class A
office and industrial property over the long term. The Company believes that
these counties are attractive for a number of reasons:

. These counties, together with Riverside and San Bernardino Counties,
comprise the second largest Consolidated Metropolitan Statistical Area
in the United States and rank as the world's 12th largest economy;

. The continuing expansion of the service-producing sector of the economy;

. Employment sectors using Class A office and industrial properties
continue to expand with the Southern California Area's continuing growth
in foreign trade and diversification of industries;

. Since 1992, there has been virtually no increase in the Southern
California Area's inventory of office space; and

. The Southern California Area's demand for quality industrial space has
spurred modest growth in new construction of industrial properties.

The Southern California Area had a 1996 total population of approximately
15.7 million people, which accounted for approximately 5.9% of the total U.S.
population. Annual population growth in the Southern California Area since
1990 has averaged approximately 190,000 persons. Of the approximately 15.7
million people in the Southern California Area, approximately 9.3 million
lived in Los Angeles County and approximately 2.6 million lived in Orange
County. Annual estimated growth in population in these counties over the next
five years is expected to be approximately 79,000 and 35,000 persons,
respectively. The following table presents the total population as a
proportion of the United States population for the Southern California Area
and California for 1980, 1990 and 1995 and the estimated population for 2000
and 2010.

Increasing Employment. The Southern California Area economy continues its
economic expansion and recovery from the recessionary conditions experienced
during the 1990-1993 period. While the Southern California Area lagged behind
the rest of the country in entering the recession, it also lagged in the
economic recovery, in part due to the cutbacks in the aerospace and defense
industries. As measured by total employment, the Southern California Area
economy "bottomed" in 1993, with 1994 showing an increase of 29,000 jobs.

Employment growth accelerated in 1995 and 1996, increasing by 112,000 and
136,000 new jobs, respectively. Of the total jobs added, approximately 61,000
and 84,000 (approximately 60% of the total) were created in Los Angeles County
in 1995 and 1996, respectively. Stimulating the economic expansion were broad-
based gains in international trade, business and professional management
services, entertainment, health and bio-med services, apparel manufacturing
and tourism.

Employment in the Southern California Area is expected to increase during
1997 and 1998, with the rate of increase once again outpacing the nation. Job
growth estimates in these two years are 145,000 and 106,000, respectively,
which correspond to percentage gains of 2.4% in 1997 and 1.7% in 1998. The
following table shows the annual change in non-agricultural jobs for the
Southern California Area for the period from 1980 through 1995, the estimated
change for 1997 and the forecasted changes for 1997 and 1998.

The unemployment rate in the Southern California Area continues to move
downward from its 1993 peak. For the U.S., the 1996 unemployment rate was
approximately 5.3% versus approximately 6.8% in California. By comparison, the
1993 unemployment rates for the U.S. and California were approximately 6.5%
and 9.2%, respectively. While the unemployment rate in the Southern California
Area has been declining in the last couple of years, it probably will remain
higher than the unemployment rate for the nation as a whole. Within the
Southern California Area, the May 1997 unemployment rates varied from a low of
approximately 3.2% in Orange County to a high of approximately 6.7% in Los
Angeles County.

Diversification of Industries. Los Angeles and Orange Counties are widely
regarded as major centers for corporate and international business. The growth
of international trade through the Los Angeles-Long Beach port complex, which
presently ranks as the largest commercial port in the United States, is
driving the growth of business in the surrounding area. While the southern
coastal Los Angeles County market, including the

100
<PAGE>

El Segundo and Long Beach submarkets, has historically been, and continues to
be, associated with the aerospace and defense industries, the downsizing of
those industries has resulted in the region becoming more diversified, with
major corporations in emerging industries such as telecommunications and
healthcare. The Company believes this diversity, which is reflected in the
Company's tenant base, has strengthened these submarkets.

Foreign Trade. The growth in the region's employment is attributable in part
to the increase in the volume of trade in the region's ports and airports,
which at the end of 1995 accounted for over 12.0% of the total trading volume
in the United States and which has grown at an average annual rate of
approximately 9.9% during the ten-year period ended in 1995 compared to an
approximately 9.0% growth rate nationally during the same period. In addition,
during 1995 the trading volume among the region's ports and airports increased
another approximately 16.0%, further securing the region's position as the
nation's leader in international trade activity. The following table shows the
growth in the Los Angeles Customs District's share of U.S. Trade for the
period from 1972 through 1995.

Growing Service Economy. Over the last 16 years, the composition of
employment in the Southern California Area has shifted, generally mirroring
national patterns. The goods-producing sector (mining, construction and
manufacturing) has declined from an approximately 28.7% share in 1980 to
approximately 19.9% in 1996. Within this sector, manufacturing accounted for
virtually the entire decline. Correspondingly, the services-producing sector
(transportation, communications and utilities; wholesale and retail trade;
finance, insurance and real estate services; and government) has expanded from
approximately 71.3% of total employment in 1980 to approximately 80.1% in
1996. The following table presents the total employment growth from 1980 to

In addition, the Southern California Area aerospace industry, which suffered
significant losses in recent years, appears to be stabilizing, although job
growth in this sector through 2005 is as likely to continue declining as it is
to rise. The local aerospace industry should benefit from new military
aircraft production, subcontractor involvement with Boeing's production of
commercial aircraft and increased satellite production. Growth is also taking
place in the technology sector which includes multi-media, digital
information, bio-med, and advanced transportation. The following table shows
the number of jobs in the aerospace/high technology industries in the Southern

Office Submarkets

General. Total office space in the Southern California Area amounts to
approximately 226 million rentable square feet. The Southern California Area
is the second largest office market in the country after the New York City
metro area (with over 800 million rentable square feet). Los Angeles County
comprises two-thirds of the metro office inventory, roughly 159 million
rentable square feet; Orange County accounts for approximately 54.2 million
rentable square feet.

Vacancy rates in the office space market in the Southern California Area are
trending downward from a high in 1991 and 1992 of approximately 19.7% to a
level at the end of 1996 of approximately 16.7%. As of March 31, 1997, the
vacancy rate for Southern California office properties continued to fall,
reaching 16.3%. The following table shows the U.S. and Southern California
Area office vacancy rates for the period from 1988 through March 31, 1997.

Net absorption in the Southern California Area during the first quarter of
1997 amounted to approximately 1.1 million rentable square feet. Annualized,
this absorption pace for 1997 would reach 4.4 million rentable square feet, a
1.3 million rentable square foot increase over 1996's 3.1 million rentable
square feet. With the improving economy, absorption has increased dramatically
from 1993's recessionary low of approximately 1.7 million rentable square
feet. By comparison, absorption in the Southern California Area ranged from
approximately 11.1 million to 11.7 million rentable square feet during the
mid-to late 1980s. Annual increases in employment during the 1980s fluctuated
between approximately 160,000 and 200,000 jobs per year, as opposed to job
losses from 1991 to 1994. The following table shows the annual absorption of

by approximately 2.0 million square feet and approximately 1.3 million
square feet, respectively.

El Segundo Office Submarket. In the El Segundo submarket the Company owns
and operates three office buildings at Kilroy LAX, and one stand alone two-
story office building. The aggregate rentable square feet of the Office
Properties in the El Segundo submarket represent approximately 22% of the
approximately 3.4 million rentable square feet of all Class A office
properties located in this submarket as of December 31, 1996.

The El Segundo submarket is an approximately 5.4 square mile area in the
southwestern coastal section of Los Angeles County. The El Segundo submarket
has the advantages of proximity to LAX without the disadvantages of being
located within the City of Los Angeles, as is the case with the submarket
located on the northeast side of LAX (the "LAX/Century Boulevard submarket").
The El Segundo submarket has a highly qualified computer and technology-based
work force. El Segundo's tax structure is as much as $6.00 per square foot per
annum lower than neighboring Los Angeles, principally attributable to lower
gross receipts and utility taxes. As a result, the El Segundo submarket has
historically enjoyed higher rental occupancy and tenant retention rates than
neighboring submarkets, such as LAX/Century Boulevard, Torrance and Carson.

The El Segundo submarket tenant base has broadened from its historic
concentration of aerospace industry tenants. A number of major corporations
have a significant presence in the El Segundo submarket, including Xerox
Corporation, Mattel, Inc., Chevron USA, Inc., AT&T, TRW Corporation and Hughes
Space & Communications.

Management believes that because of the high visibility and strategic
location of the four office buildings located in the El Segundo submarket, the
El Segundo Office Properties have higher occupancy and tenant retention than
other properties within this submarket and have achieved higher rental rates.
The vacancy rate of Class A office buildings in the El Segundo submarket was
approximately 15.9%, as of June 30, 1997, compared to approximately 1.4% for
the Company's El Segundo Office Properties as a whole, as of June 30, 1997.
The

105
<PAGE>

mean asking annual rental rate in the El Segundo submarket, as of June 30,
1997, was approximately $22.93 per square foot for Class A office buildings
compared to an average asking mean rental rate of $25.20 per square foot for
the Company's El Segundo Office Properties as a whole, as of June 30, 1997.

Through June 30, 1997, net absorption of office space in the El Segundo
submarket was 32,000 rentable square feet. This gain represents a reversal of
the last several years during which the local office market recorded negative
office space absorption. The positive absorption reflects the growth of and
increase in the number of local tenants which are still overwhelmingly
aerospace but increasingly with a high technology orientation, such as
software and satellite development businesses.

No new office buildings are under construction and, to the Company's
knowledge, no new construction is presently projected in the near future in
the El Segundo submarket. The following tables show the comparative vacancy
rates of Class A office space in the El Segundo submarket and Kilroy LAX, and
the comparative mean asking rents of Class A office space in the El Segundo
submarket and Kilroy LAX, respectively.

The local Class A office market shows evidence of increasing improvement.
Vacancy has declined from nearly 20% estimated as of September 30, 1996 to
15.9% as of June 30, 1997. Correspondingly, overall rents have increased by
over 4% during this same time frame. The Company's asking rents have increased
over this same period by approximately 5%. Nearly two-thirds of the available
space as of June 30, 1997 is located in one major building, 200 North
Sepulveda Boulevard. This space which had been vacated by Hughes Electronics
has undergone significant rehabilitation during much of 1996. Of the 500,000
square feet of net rentable area at 200 North Sepulveda Boulevard, 156,000
square feet has been leased as of June 30, 1997.

Management believes that rental increases should continue. Contributing
factors to this expectation include the submarket's expanding economy which is
already evidenced in declining vacancy rates, the limited availability of
large blocks of office space and lower rental rates than those offered in the
nearby West Los Angeles office submarket and no known increases in the
competitive supply of office space.

Long Beach Airport Area Office Submarket. As of June 30, 1997, the vacancy
rate of Class A office buildings in the Long Beach Airport area was
approximately 3.9% as compared to approximately 2.0% for the

106
<PAGE>

Company's Long Beach Office Properties. The vacancy figures for this market
reflect the results of a market that has significantly "tightened" during the
preceding nine months. By comparison, vacancy for the Long Beach Airport area
as a whole is 15.1% as of June 30, 1997. Of the 190,000 rentable square feet
estimated to be available in Class A buildings as of September 30, 1996 less
than 60,000 square feet remains available as of June 30, 1997. The absorption
provides evidence of the improving regional economy and the strategic location
of Class A office space in this submarket.

Class A rents in the Long Beach Airport Area have benefited from the
improving market conditions. Mean asking rents have increased 6% over rents in
these same buildings, as of September 30, 1996. Mean asking rents at Kilroy
Long Beach Phase II have increased by 7.5% over rents as of September 30,
1996.

The market outlook for further rental increases is favorable given the
limited amount of available space, the improving regional economy and the lack
of new space. Available space for technology companies is particularly
difficult to find, and buildings which offer advanced telecommunications
capabilities, such as the Kilroy Long Beach Office Properties should provide a
competitive advantage.

The following tables show the comparative vacancy rates of Class A office
space in the Long Beach submarket and Kilroy Long Beach, and the comparative

Santa Monica Office Submarket. In the Santa Monica office submarket, the
Company recently purchased one 95,000 square foot office building which serves
as the headquarters for Sony Corporation's music division. The Sony Building
represents about 3.5% of the approximately 2.7 million rentable square feet of
all Class A office properties in this submarket as of June 30, 1997. Santa
Monica's office tenant base is composed of companies in the entertainment,
financial services, legal, real estate and advertising industries.

Santa Monica's office market has emerged as a principal Class A office
market, with many of its office buildings ranked among the most prestigious
buildings in the Los Angeles area. The attractiveness of this market stems
from its proximity to the ocean, the breadth of local retailing and
restaurants, the generally adjacent upscale residential neighborhoods which
appeal to the enterpreneurs and executives involved in office leasing
decisions,

107
<PAGE>

and the entertainment industry nucleus that is now in place (Sony, MGM and a
host of post-production companies) and draws additional companies. Another
factor contributing to Santa Monica's office market success has been the
availability of large-scale office development projects featuring generally
low-rise, campus style product. With continued growth anticipated for the
entertainment industry coupled with an improving regional economy, the rental
rate and vacancy outlook for Santa Monica remains favorable.

Mean asking rents for Class A office space range between $30 to $42 per
annual rentable square foot and are among the highest in the Los Angeles area.
By comparison, the Sony Building annual rents are $33 per rentable square
foot. Vacancy among Class A buildings is 16.7% which is above the 9.3% vacancy
rate as of June 30, 1997, for the Santa Monica office market as a whole. The
Sony Building was 100% leased as of June 30, 1997.

Office development economics in the form of relatively high rents have
reached a point that may encourage new construction. Two projects in the
vicinity of the Sony Building where new office development is entitled include
the Arboretum (130,000 rentable square feet) and Water Garden Phase II
(650,000 rentable square feet). No public announcements with respect to the
commencement of construction of these two projects have been made at this
time. The following tables show the comparative vacancy rates of Class A
office space in the Santa Monica submarket and the Sony Complex, and the
comparative mean asking rents of Class A office space in the Santa Monica
submarket and the Sony Complex, respectively.

Irvine Spectrum Office Submarket. The Company recently purchased one Office
Property located at 111 Pacifica (the "Pacifica Building") in Irvine which
encompasses 67,425 rentable square feet, and which is part of the Irvine
"Spectrum" project. This Property represents approximately 11% of the 622,000
rentable square feet of Class A office space in the Spectrum, and was 100%
leased as of June 30, 1997.

The Irvine Spectrum has become one of Southern California's most attractive
destinations for corporate headquarters and expanding high-tech industries
relocating from other parts of the Los Angeles Basin. The Spectrum is home to
over 2,200 companies employing 36,000 people. Besides being conveniently
located near Orange County's John Wayne Airport, the Spectrum enjoys great
surface accessibility due to its location at the convergence of Interstates 5
and 405. The Spectrum also attracts tenants because of its proximity to
affluent neighborhoods in Mission Viejo, Aliso Viejo, Lake Forest and Laguna
Hills. Further contributing to the success of the Spectrum is a wide variety
of office product which provides space into which Spectrum tenants can expand.

Class A office rents range from approximately $22 to $25 per rentable square
foot per year. By comparison, the annual mean asking rent at the Pacifica
Building is $23.40 per rentable square foot. Vacancy among Class A buildings
in the Spectrum is 7.3% as of June 30, 1997, somewhat lower than the overall
surrounding submarket vacancy rate of 8.3% as of March 31, 1997.

Demand for the office space is expected to increase as the relocation and
success of high-tech firms attract accounting and law firms that cater to the
high-tech industry. Construction at the Spectrum will continue for the
foreseeable future as The Irvine Company expects to invest approximately $1
billion in office, retail and industrial space, including a new office high-
rise, a cluster of one-story office buildings and a 250,000 rentable square
foot expansion of the existing Irvine Entertainment Center. The following
tables show the comparative vacancy rates of Class A office space in the
Irvine Spectrum submarket and the Pacifica Building, and the comparative mean
asking rents of Class A office space in the Irvine submarket and the Pacifica
Building, respectively.

Thousand Oaks Submarket. The Company owns a stand alone three-story Office
Property located at 2829 Townsgate Road in Thousand Oaks, California. The City
of Thousand Oaks has approximately 108,000 residents, and is located 39 miles
northwest of Los Angeles in Ventura County. Ventura County had a 1996
population of approximately 720,000 persons. The County is home to companies
in various industries including high technology and pharmaceuticals, such as
Amgen Inc. As of March 31, 1997, the vacancy rate of office space in the
Ventura County office submarket was approximately 15.2%. During the years
ended December 31, 1996 and 1995, there was net absorption in the Ventura
County office submarket of approximately 79,000 and 157,000 rentable square
feet of office space, respectively. For the first quarter ending March 31,
1997, Ventura County lost approximately 39,000 square feet of occupied space.
This obscures the net absorption of 16,000 rentable square feet of Class A
office space in the same period. The average annual effective gross rent for
office space in the Ventura County office submarket as of March 31, 1997 was
$16.68 per square foot.

Calabasas Office Submarket. The Company recently acquired one Class A office
property located at 26541 Agoura Road in Calabasas containing approximately
91,000 rentable square feet of office space. The Calabasas office submarket
houses a wide variety of tenants from high-technology to professional service
firms.

109
<PAGE>

The Calabasas office market runs along the Highway 101 and is located in the
western extreme of the larger West San Fernando Valley office submarket. The
attractiveness of the Calabasas market can be attributed to several factors,
not the least of which are a lower tax rate and reduced cost of doing business
when compared with office space in Los Angeles. Tenants can expect to save
from 26% to 32% over the nearby Warner Center in Woodland Hills in the City of
Los Angeles. This suburban, low-rise campus office market represents a newer
stock of office space which appeals to executives in a variety of industries
who reside in nearby affluent residential communities. Besides offering high
visibility and excellent freeway access, surface parking in Calabasas is
provided free.

At June 30, 1997, the Calabasas Office Property was fully leased, as
compared to the Calabasas Class A office market and the West San Fernando
Valley office market which were at approximately 10.5% and 14.2% vacancy
levels, respectively. In 1996, Calabasas office market absorption jumped to
approximately 137,600 rentable square feet from a 1995 loss of approximately
76,700 occupied square feet. As of June 30, 1997, rents at Class A buildings
averaged $21.53 per rentable square foot per year on a full-service gross
basis. By comparison, the Calabasas Office Property currently has a mean
asking rent of $22.20 per square foot per year on a full-service gross basis.

The Calabasas market is expected to benefit from the expansion of existing
tenants as well as relocations from the Warner Center in Woodland Hills and
from Los Angeles in general. Construction has just begun to anticipate this
increase in Calabasas demand as two new Class A projects of 47,000 and 61,000
square feet are currently under way.

Industrial Submarkets

For the first time this decade the industrial vacancy rate in the Southern
California Area has dropped below the national average. As of March 31, 1997,
available industrial space in the Southern California Area totaled
approximately 1.2 billion rentable square feet. Vacancy rates in the
industrial space market in the Southern California Area have declined from a
high of approximately 13.8% in 1992 to approximately 7.3% at March 31, 1997.
By comparison, the national average, as of March 31, 1997, was 8.1%. As of
June 30, 1997, the vacancy rate for the Industrial Properties in the Southern
California Area was approximately 3.3%.

The following table shows the U.S. and Southern California Area industrial
vacancy rates for the period from 1991 through the first quarter of 1997.

Much of the existing industrial space in the Southern California Area is
considered to be functionally obsolete due to its age, services and/or
configuration. As a result, the Southern California Area inventory for
industrial space is beginning to experience a growth in new construction
primarily of build-to-suit. Speculative construction in the first quarter of
1997 was approximately 9.6 million rentable square feet (representing
approximately 0.8% of the region's inventory) compared to approximately 8.5
million in 1996.

North Orange County Industrial Submarket. The Company recently acquired
seven industrial buildings in Brea (the "Brea Industrial Properties"), part of
the North Orange County industrial submarket. The Brea Industrial Properties
encompass approximately 276,000 rentable square feet and, as of June 30, 1997,
were 97.8% leased. As of March 30, 1997, the North Orange County industrial
submarket contained approximately 63.1 million rentable square feet,
approximately 9.9% of which was vacant. Vacancy rates in this submarket have
dropped nearly 50% from 1991 levels and 25% since 1995. Even in the face of
speculative building, most of which has been preleased, vacancy rates are
expected to decline further while 1997 rental rates in the North Orange County
Industrial submarket could rise by as much as 15% over year-end 1996 levels.

Central Orange County Industrial Submarket. The Company currently owns six
industrial buildings encompassing approximately 565,000 rentable square feet
located at 3340 La Palma Avenue, 1000 East Ball Road, 1230 S. Lewis Street,
4155 E. La Palma, 4125 La Palma Avenue and 5325 East Hunter Avenue. These
buildings were 100.0% leased as of June 30, 1997. The Central Orange County
industrial submarket held approximately 31.1 million rentable square feet with
an approximate 9.9% vacancy rate, as of March 31, 1997. As is the case with
the North Orange County submarket, vacancy rates in this submarket are just
two-thirds of 1991 levels and have declined steadily since 1995. Vacancy rates
are expected to decline and rental rates increase as a shortage of developable
land keeps existing space in high demand.

West Orange County Industrial Submarket. In this submarket, the Company
currently owns five industrial buildings located at 12681/12691 Pala Drive,
12752-12822 Monarch Street, 12400 Industry Street and 7421 Orangewood Avenue.
As of June 30, 1997, the five buildings encompassed approximately 509,000
rentable square feet of which 2.9% was available for lease. As a submarket,
vacancy rates were 8.3%, as of March 31, 1997, and aggregate rentable area
totaled 36.4 million rentable square feet. By the end of 1997, rental rates
are expected to rise by up to 10% over 1996 levels.

Orange County Airport Area Industrial Submarket. The Company recently
acquired six buildings totaling approximately 696,000 rentable square feet in
Irvine and Santa Ana, part of the Orange County Airport Area industrial
submarket, located at 17150 Von Karman, 9451 Toledo Way, 184-220 Technology
Drive, 1675 MacArthur Boulevard, 1483 Franklin Avenue and 2055 S.E. Main
Street. As of June 30, 1997, these properties were 96.4% leased. Within the
entire submarket, vacancy rates among the 73.5 million rentable square feet
were 8.4% as of March 31, 1997. Vacancy and rental rates in this submarket
have stabilized after several years of fluctuation. By the year ended December
31, 1997, rental rates may rise up to 15% over 1996 levels as speculative
construction is expected to fall short of anticipated demand.

Ventura Coastal Plain Office and Industrial Submarkets. The Company recently
acquired four buildings consisting of approximately 276,000 rentable square
feet of office and research and development space in Camarillo located at
5151-5155 Camino Ruiz, located within the Ventura Coastal Plain industrial
submarket. This property was 100% leased as of June 30, 1997. As of March 31,
1997, the Ventura Coastal Plain industrial submarket contained approximately
155 million rentable square feet, of which approximately 6.7% was vacant.
Vacancy rates have been slowly declining while annual asking rents have
rebounded from a 1996 low of $5.76 to $6.60, as of March 31, 1997. The Ventura
Coastal Plain submarket is the center of commerce for Ventura County which is
actively attracting new businesses and helping local businesses expand. Sales
prices and lease rates within the county are expected to rise through 1997 as
the market tightens, especially among warehouse and multi-tenant industrial
properties.

The Ventura Coastal Plain Office Market has historically been dependent on
the expansion of local businesses, government services and the Point Mugu
Naval Base to attract new jobs and business to the area. Lease and vacancy
rates in this submarket, which is characterized by a large supply of small
office space,

111
<PAGE>

averaged $16.20 and 16.1% as of year-end 1996, respectively. These indicators
may improve if migrating Los Angeles companies are attracted by the Ventura
Coastal Plain Office Market's varied selection of space and more reasonable
rates.

Ontario/Mira Loma Industrial Submarket. The Company recently acquired one
building containing approximately 154,000 rentable square feet of rentable
space located at 821 S. Rockefeller Drive in Ontario, part of the Ontario/Mira
Loma industrial submarket, located approximately 35 miles east of Los Angeles.
As of June 30, 1997, this property was 100% leased. The Ontario/Mira Loma
industrial submarket contained approximately 57.3 million rentable square feet
of which approximately 5.8% was available for lease, as of March 31, 1997.
Asking rents in this submarket have increased for the first time since 1994
and significant amounts of new construction are now underway. Strong
preleasing activity has characterized this submarket in 1997, as international
business has expanded in Southern California. The Ontario/Mira Loma Industrial
submarket is located within the two county Riverside-San Bernardino
metropolitan area which offers excellent freeway and rail access, a solid
labor base and an industrial vacancy rate of 8.0% as of the end of the first
quarter of 1997.

Torrance/Harbor City Office and Industrial Submarket. The Company recently
acquired two office/industrial buildings located at 23600 and 23610 Telo
Avenue, which encompass approximately 80,000 rentable square feet in the
Torrance/Harbor City industrial submarket, located approximately 17 miles
southwest of downtown Los Angeles. As of June 30, 1997, this property was
100.0% leased. However, subsequent to June 30, 1997, one of the tenants at
this Property terminated its lease and approximately 48.1% of the rentable
square feet of the Property is presently available for lease. As of March 31,
1997, the Torrance/Harbor City industrial submarket contained approximately
29.7 million rentable square feet of which approximately 6.2% was available
for lease. Vacancy rates in this submarket have steadily declined over the
past four years. Strategic proximity to ports and the unavailability of large
blocks of developable land within the South Bay market, of which the
Torrance/Harbor City industrial submarket is a part, suggest that this trend
will continue.

The Torrance office submarket contains approximately 3.3 million rentable
square feet of office space. Vacancy rates appear to have stabilized after
having dropped to approximately 15.9%, as of March 31, 1997 (approximately 3%
lower than year-end 1996 levels), and are at their lowest level since 1991.

El Segundo/LAX Industrial Submarket. The Company currently owns four
buildings comprising approximately 390,000 rentable square feet of industrial
space located at 2031 E. Mariposa, and 2260, 2265 and 2270 E. El Segundo
Boulevard, in El Segundo, part of the El Segundo/LAX industrial submarket. As
of June 30, 1997, 1.9% of this space was vacant. As of March 31, 1997, the El
Segundo/LAX industrial submarket showed vacancy rates of 5.7%, among the
lowest of the decade, and rental rates were at approximately $7.78 per square
foot per year. Within the South Bay region, of which the El Segundo/LAX
industrial submarket is a part, much of the developable land is burdened with
environmental cleanup costs. As a result, rents should continue to rise given
constraints on developable industrial land.

Eastern San Gabriel Valley Industrial Submarket. The Company presently plans
to complete the acquisition of three buildings located at 20553 Walnut Drive,
which contain approximately 165,000 rentable square feet of industrial space
which was 100% leased as of June 30, 1997. As of March 31, 1997, vacancy rates
in the Eastern San Gabriel Valley Industrial Submarket stood at 6.4%, the
result of a steady decline through the decade. Demand in this submarket is
expected to rise as tenants choose to relocate from older industrial space
into new construction. Consequently, rental and vacancy rates should improve
further, especially for better quality industrial space.

SAN DIEGO MARKET

The Company has contracted to acquire one industrial building, encompassing
approximately 39,700 rentable square feet located at 6828 Nancy Ridge Drive.
The San Diego metropolitan area had a 1996 total population of approximately
2.7 million people making it the 16th largest metropolitan area in the United
States.

112
<PAGE>

The median household income in the San Diego metropolitan area, including San
Diego County, averaged approximately $39,400 in 1996 and is expected to
increase by nearly 1.4% annually over the next five years. This median
household income is about 8% higher than the 1996 national average of $36,600.

Between May 1996 and May 1997, the San Diego metropolitan area had the 18th
largest employment level in the nation. Between 1990 and May 1997, employment
increased by 42,000 jobs, or 0.7% per year, to approximately 1,009,000 jobs as
of May 1997 compared to approximately 967,000 jobs in 1990. The San Diego
metropolitan area's employment growth rate of approximately 3.2%, for the 12-
month period from May 1996 to May 1997, was the 18th largest increase in the
country. The major economic factors behind the San Diego economy are (i) the
proximity to the Mexican border which allows manufacturers to ship their
products to Mexico for assembly and then re-ship such products duty-free to
the U.S. for final assembly and distribution; (ii) the presence of one of
California's three main port complexes which allows the region to access the
growing Pacific Rim economies; (iii) the expansion and diversification of the
technology base which includes the nation's fourth largest concentration of
bio-technology firms; and (iv) the growth in the manufacturing base for
wireless communications.

The vacancy rate, as of December 31, 1996, for the approximately 80.5
million rentable square feet of industrial space in San Diego County was
approximately 8.8%, well below the 1994 and 1995 vacancy rates of
approximately 13.6% and 10.1%, respectively. Rental rates for 1996 averaged
approximately $0.59 per rentable square foot per month, calculated using
leases written on a triple net basis. The 1996 average rental rate
demonstrated an increase of 3.5% and 1.7% over the 1994 and 1995 rental rates,
respectively.

The North San Diego County industrial market comprises approximately 22
million rentable square feet of industrial space of which approximately 6.5%
was vacant as of December 31, 1996. This industrial market contains the three
industrial submarkets of Miramar, Sorrento Mesa and Sorrento Valley, where
vacancy rates, as of December 31, 1996, ranged from approximately 4.8% to 7.6%
and annual rental rates from approximately $6.00 to $8.88. The stimulus for
industrial growth in the respective North San Diego County submarkets stems
from the influx of high-technology businesses such as wireless communications,
computer software and bio-technology. In the Sorrento Mesa and Sorrento Valley
submarkets, where research and development industrial space tends to be newer
than that of the Miramar submarket, higher rents and lower vacancy rates are
expected since industrial expansion is constrained by a shortage of
developable land.

SEATTLE MARKET

The Company owns three office buildings located at the SeaTac Office Center
in the City of SeaTac, just south of Seattle, Washington. The Seattle
metropolitan area (formally the Seattle-Tacoma CMSA) reported a 1996
population of approximately 3.3 million. Seattle ranks as the 13th largest
metropolitan area in the country. Since 1990, the region has added on average
58,000 new residents. The expectation is that the region will continue to
increase, expanding annually over the next five years at approximately 53,000
new residents. Median household income in the Seattle metropolitan area is
estimated at $44,000 in 1996 and exceeds national median household income by
over 20%.

Employment in the Seattle metropolitan area stood at an estimated 1.3
million in 1996. During the 1990s, employment growth has averaged about 25,000
per year. Recent employment statistics for the 12-month period between May
1996 and May 1997 show that the Seattle area added nearly 66,000 jobs, the
third largest numeric increase in the country. On a percentage basis,
employment in the Seattle area expanded by 5.4% during this same 12-month
period, the fourth largest percentage increase in the country.

As of December 31, 1992, the vacancy rate for office space in the Seattle
metropolitan area was approximately 15.5%. Since then, this rate has steadily
declined to a level of 12.4%, as of December 31, 1994, and 7.7%, as of June
30, 1997. Seattle's aggregate office space stands at about 53.8 million
rentable square feet. As of June 30, 1997, two new projects totaling about one
million square feet are under construction.

SAN JOSE MARKET

The Company has contracted to acquire two research and development/flex
space industrial properties, encompassing approximately 195,200 rentable
square feet located at 1961 Concourse Drive and 1710 Fortune Drive. The 1996
population of the San Jose metropolitan area within Santa Clara County, was
slightly under 1.6 million people which places this region among the
30 largest metropolitan areas in the country. The median household income for
1996 averaged approximately $58,200 which is nearly 60% above the national
median for 1996.

The San Jose metropolitan area had an employment level of approximately
865,000 jobs as of December 31, 1996 and is among the 30 largest employment
levels in the nation. Since 1990, the employment level has grown at an average
annual rate of 1.2% or an aggregate of nearly 60,000 jobs. The San Jose
metropolitan area's employment growth rate of approximately 3.9%, for the 12-
month period from May 1996 to May 1997, was the 10th largest increase in the
country. The major economic factors of the San Jose metropolitan area economy
and includes such industries as aerospace, computers, electronics, bio-
technology and communications.

The San Jose industrial market comprises about 200 million rentable square
feet of industrial space. Although vacancy rates for industrial space in the
San Jose market were as high as 22% in 1990 and 1991, vacancy rates for
industrial space fell to approximately 3.8% as of December 31, 1996. Rental
rates for 1997 are expected to increase from approximately 10% to 20% due to
concurrent growth in the high-technology electronics industry. Consequently,
speculative construction is rising, and build-to-suit and preleasing
activities are expected to be strong considering local land costs and the
limited availability of suitable industrial building sites.

INSURANCE

Management believes that the Properties are covered by adequate
comprehensive liability, rental loss, and all-risk insurance, provided by
reputable companies, with commercially reasonable deductibles, limits and
policy specifications customarily carried for similar properties. There are,
however, certain types of losses which may be either uninsurable or not
economically insurable, such as losses due to floods, riots or acts of war.
Should an uninsured loss occur, the Company could lose both its invested
capital in and anticipated profits from the property.

UNINSURED LOSSES FROM SEISMIC ACTIVITY

The Properties are located in areas that are subject to seismic activity.
Although the Company has earthquake insurance on certain of the Properties,
should any Property sustain damage as a result of an earthquake, or should
losses exceed the amount of such coverage, the Company may incur uninsured
losses or losses due to deductibles or co-payments on insured losses.

Each of the Properties owned by the Company has been recently reviewed by an
independent engineering consultant. Each of the office buildings located at
Kilroy LAX, Kilroy Airport Center Long Beach and the SeaTac Office Center was
reviewed as part of the respective office complex ("Office Complex") in which
each is located and the following Office Complex data summarizes the findings
with respect to each Office Complex taken as a whole. The review of each of
the Properties and Office Complexes included a review of the probable loss
associated with certain seismic activity for the "as-is" building shell
construction. The estimated property damage loss associated with building
shell construction and related business interruption for the Office Complexes
and each of the other Properties owned by the Company was estimated based upon
site-specific seismic ground motion intensities expected to occur at least
once during a 50-year period. For 50-year seismic ground motion intensity,
these property damage loss evaluations indicate that none of the Office
Complexes would be expected to incur property damage losses in excess of
approximately 10% of their respective estimated replacement cost value ("RCV")
and that none of the remaining office buildings would be expected to incur
property damage losses in excess of approximately 16.5% of their respective
RCV. With respect to the Industrial Properties, none of the buildings would be
expected to incur property damage losses in excess of approximately 17.2% of
their respective RCV from a 50-year seismic event.

114
<PAGE>

The Company has insurance for loss for substantially all of the Properties
in the event of damage resulting from earthquake activity, which consists of
primary loss insurance of $1.0 million and $10.0 million supplemental coverage
for losses in excess of $11.0 million. Both the primary loss and supplemental
coverage are subject to deductibles equal to 25% of the insurable values for
each location per occurrence and, for the primary coverage, a minimum
deductible of $250,000 (to the extent that such amount is greater than 25% of
the insurable values at such location) to each location per occurrence. The
Company evaluates its earthquake insurance coverage on a periodic basis by
comparison to market rates and industry standards and may revise the extent
and scope of its earthquake insurance coverage in the future. The Company's
earthquake insurance might not be sufficient to replace all buildings damaged
by earthquake activity.

GOVERNMENT REGULATIONS

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

Costs of Compliance with Americans with Disabilities Act. Under the ADA, all
places of public accommodation are required to meet certain federal
requirements related to access and use by disabled persons. Compliance with
the ADA might require removal of structural barriers to handicapped access in
certain public areas where such removal is "readily achievable." Noncompliance
with the ADA could result in the imposition of fines or an award of damages to
private litigants. The impact of application of the ADA to the Company's
properties, including the extent and timing of required renovations, is
uncertain. If required changes involve a greater amount of expenditures than
the Company currently anticipates or if the changes must be made on a more
accelerated schedule than the Company currently anticipates, the Company's
ability to make expected distributions to stockholders could be adversely
affected.

Environmental Matters. Under various federal, state and local laws,
ordinances and regulations relating to the protection of the environment, an
owner or operator of real estate may be held liable for the costs of removal
or remediation of certain hazardous or toxic substances located on or in the
property. These laws often impose liability without regard to whether the
owner was responsible for, or even knew of, the presence of such hazardous or
toxic substances. The costs of investigation, removal or remediation of such
substances may be substantial, and the presence of such substances may
adversely affect the owner's ability to rent or sell the property or to borrow
using such property as collateral. In addition, the presence of such
substances may expose the Company to liability resulting from any release of
or exposure to such substances. Persons who arrange for the disposal or
treatment of hazardous or toxic substances at another location may also be
liable for the costs of removal or remediation of such substances at the
disposal or treatment facility, whether or not such facility is owned or
operated by such person. Certain environmental laws impose liability for
release of asbestos-containing materials into the air, and third parties may
also seek recovery from owners or operators of real properties for personal
injury associated with asbestos-containing materials and other hazardous or
toxic substances. In connection with the ownership (direct or indirect),
operation, management and development of real properties, the Company may be
considered an owner or operator of such properties or as having arranged for
the disposal or treatment of hazardous or toxic substances and, therefore,
potentially liable for removal or remediation costs, as well as certain other
related costs, including governmental penalties and injuries to persons and
property.

115
<PAGE>

All of the Properties have been subject to Phase I or similar environmental
assessments by independent environmental consultants. Phase I assessments are
intended to discover information regarding, and to evaluate the environmental
condition of, the surveyed property and surrounding properties. Phase I
assessments generally include an historical review, a public records review,
an investigation of the surveyed site and surrounding properties, and
preparation and issuance of a written report, but do not include soil sampling
or subsurface investigations. Such reports have revealed that historical
operations at or in the vicinity of certain of the Existing and Acquired
Properties, including the operation of underground storage tanks, may have
caused soil or groundwater contamination on such properties. For example, with
respect to Kilroy Long Beach Phase I, the Company's environmental
investigations revealed the site's possible prior use as a Nike air defense
command center or missile storage facility and the existence and use of former
and current underground storage tanks on or near the Property. The Company's
investigation included whether the site might have been used previously for
the storage of missiles containing nuclear warheads, and did not reveal any
facts that would indicate that the prior use of the site would result in a
material risk of environmental liability. Consequently, the Company does not
believe that this site constitutes a risk of a liability that would have a
material adverse effect on the Company's financial condition or results of
operations taken as a whole. In connection with the preparation of the Phase I
environmental survey with respect to the Industrial Property located at 12752-
12822 Monarch Street, soil sampling revealed trace elements of contamination
with cleaning solvents. However, based on the level of contamination noted in
the environmental survey, management does not believe that such contamination
will have a material adverse effect on the Company's financial condition or
results of operations, taken as a whole.

MORTGAGE DEBT

As of July 31, 1997, the Company had an aggregate of $190.7 million of
outstanding indebtedness secured by certain of the Properties. Under the
Credit Facility, the Company had outstanding indebtedness at July 25, 1997 of
approximately $95.0 million secured by substantially all the Properties other
than the Properties securing the Mortgages Loans. The obligations outstanding
under the Credit Facility bore a weighted average interest rate of 7.5%, and
mature in May 1999, subject to a one year extension. The Company also had
outstanding mortgage indebtedness of $84.0 million under the $84.0 Million
Loan. Such obligation is secured by all of the Office and Industrial
Properties owned by the Company upon consummation of the IPO, except for the
five office buildings at Kilroy Long Beach and the three office buildings
comprising the SeaTac Office Center. The $84.0 Million Loan bears an interest
rate of 8.35% and matures on February 1, 2022, subject to an increase in the
interest rate on January 31, 2005 to the greater of 13.35% and the sum of the
yield of noncallable U.S. Treasury Securities maturing 15 years from such date
plus 5.0%. The Company also had outstanding $14.0 million under the SeaTac
Loan which is secured by the three buildings comprising the SeaTac Office
Center. The SeaTac Loan bears interest at LIBOR plus 1.5% and matures in
January 1998. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations--Liquidity and Capital Resources" and "Description
of Indebtedness."

MANAGEMENT AND EMPLOYEES

The Company conducts substantially all of its operations through the
Operating Partnership and substantially all of its development activities and
related operations through the Services Company. The Company generally has
full, exclusive and complete responsibility and discretion in the management
and control of the Operating Partnership, but not of the Services Company.

LEGAL PROCEEDINGS

Neither the Company nor any of the Properties is subject to any material
litigation nor, to the Company's knowledge, is any material litigation
threatened against any of them, other than routine litigation arising in the
ordinary course of business, which is expected to be covered by liability
insurance. In May 1994, KI permitted an uncontested foreclosure by the Bank of
America on a five-story office building located in El Segundo, California as
part of an overall renegotiation of KI's loans and lines of credit. In July
1993, KI sold Kilroy Long Beach Phase I to the mortgagee thereof, at a
purchase price slightly in excess of the outstanding balance of such mortgage.
KI continued to lease and manage such facility after such sale. In December
1994, the owner of Hidden River Corporate Park located in Tampa, Florida
permitted the uncontested foreclosure of the deeds of trust and certain other
property pledged as collateral to secure certain development loans related to
such property. KI developed the property, an approximately 210-acre office
park, and at the time of the foreclosure John B. Kilroy, Sr. and John B.
Kilroy, Jr. were limited partners in the company that owned the property.

POLICIES WITH RESPECT TO CERTAIN ACTIVITIES

The Company's policies with respect to the following activities have been
determined by the Board of Directors and may be amended or revised from time
to time at the discretion of the Board of Directors, without a vote of the
stockholders of the Company, if they determine in the future that such a
change is in the best interests of the Company and its stockholders.

INVESTMENT POLICIES

Investment in Real Estate or Interests in Real Estate. The Company conducts
all its investment activities through the Operating Partnership and will
continue to do so until all Units of the Operating Partnership have been
redeemed by the Company or exchanged for shares of Common Stock and the
Operating Partnership ceases to exist. During such period, the proceeds of all
equity capital raised by the Company will be contributed to the Operating
Partnership in exchange for Units in the Operating Partnership. The investment
objectives of the Company are to achieve stable cash flow available for
distributions and, over time, to increase cash flow and portfolio value by
actively managing the Properties, by developing properties, by acquiring
additional properties that, either as acquired or after value-added activities
by the Company (such as improved management and leasing services and
renovations), will produce additional cash flows and by expanding its
management, development and leasing business with third-parties. The Company's
policy is to develop and acquire properties primarily for generation of
current income and appreciation of long-term value.

The Company pursues its investment objectives primarily through the
ownership of quality office and industrial properties. The Company currently
is contemplating development of additional office buildings and industrial
buildings primarily in Southern California, although future investments could
be made outside of such area or in different property categories if the Board
of Directors determines that such acquisitions and developments would be
desirable. The Company has no limit on the amount or percentage of its assets
invested in any single property or group of related properties. The Board of
Directors may establish limitations as it deems appropriate from time to time.
No limitations have been set on the number of properties in which the Company
seeks to invest or on the concentration of investments in any one geographic
region.

The Company may develop, purchase or lease income-producing properties for
long-term investment and expand, improve or sell its properties, in whole or
in part, when circumstances warrant. The Company may also participate with
other entities in property ownership through joint ventures or other types of
co-ownership. Equity investments by the Company may be subject to existing or
future mortgage financing and other indebtedness which will have priority over
the equity interests of the Company.

As the sole general partner of the Operating Partnership, Kilroy Realty
Corporation also determines the investment policies of the Operating
Partnership. Under the Partnership Agreement, all future investments must be
made through the Operating Partnership. See "Partnership Agreement of the
Operating Partnership--Management."

Investments in Real Estate Mortgages. While the Company emphasizes equity
real estate investments, the Company may, in its discretion, invest in
mortgages and other real estate interests consistent with the Company's
qualification as a REIT. The Company has not previously invested in mortgages
and does not presently intend to invest in mortgages or deeds of trust, but
may invest in participating or convertible mortgages if the Company concludes
that it may benefit from the cash flow or any appreciation in the value of the
subject property. Such mortgages are similar to equity participations.
Investments in real estate mortgages run the risk that one or more borrowers
may default under such mortgages and that the collateral securing such
mortgages may not be sufficient to enable the Company to recoup its full
investment.

Securities of or Interests in Persons Primarily Engaged in Real Estate
Activities and Other Issuers. Subject to the percentage of ownership
limitations and gross income tests necessary for the Company to qualify and
maintain its status as a REIT, the Company may invest in securities of other
entities engaged in real estate activities or securities of other issuers See
"Federal Income Tax Considerations--Taxation of the Company." Except for its
investment in the Services Company, the Company does not currently intend to
invest

118
<PAGE>

in the securities of other issuers except in connection with acquisitions of
indirect interests in properties (normally general or limited partnership
interests in special purpose partnerships owning properties) and in connection
with the acquisition of substantially all of the economic interest in a real
estate-related operating business where such investments would be consistent
with the Company's investment policies. Investment in these securities is also
subject to the Company's policy not to be treated as an investment company
under the Investment Company Act of 1940. The risks of investing in real
estate-related operating businesses include the risk that contracts with third
parties may be terminated by such third parties, not renewed upon expiration
or renewed on less favorable terms, and the risk that fee income will decrease
as a result of a decline in general real estate market conditions.

DISPOSITIONS

The Company has no current intention to cause the disposition of any of the
Properties, although it reserves the right to do so if the Board of Directors
determines that such action would be in the best interests of the Company. The
disposition of the Office Property located at 2260 E. Imperial Highway at
Kilroy LAX in El Segundo is subject to the approval of limited partners of the
Operating Partnership. In addition, in connection with the acquisition of the
Warren Technology Center and the office building located at 111 Pacifica,
Irvine, California, the Company agreed not to dispose of such Properties in a
taxable transaction before January 31, 1999, or thereafter unless a shelf
registration statement is then in effect with respect to the shares of Common
Stock issuable upon the exchange of the 165,102 limited partnership Units
issued to limited partners in connection with the acquisition of such
Properties. See "Partnership Agreement of the Operating Partnership--
Redemption/Exchange Rights" and "--Certain Limited Partner Approval Rights."

FINANCING

The Company has established its debt policy relative to the market
capitalization of the Company rather than to the book value of its assets, a
ratio that is frequently employed. The debt-to-total market capitalization
ratio (i.e., the total consolidated debt of the Company as a percentage of the
aggregate market value of the issued and outstanding shares of Common Stock
and Units plus total consolidated debt) of the Company, as of June 30, 1997,
was approximately 29.9%. Giving pro forma effect to the Offering and the
application of the net offering proceeds therefrom as set forth under the
caption "Use of Proceeds," the Company's debt-to-market capitalization ratio
as of July 31, 1997 would have been 12.1%. This ratio will fluctuate with
changes in the price of the Common Stock (and the issuance of additional
shares of Common Stock) and differs from the debt-to-book capitalization
ratio, which is based upon book value. As the debt-to-book capitalization
ratio may not reflect the current income potential of a company's assets and
operations, the Company believes that debt-to-total market capitalization
ratio provides a more appropriate indication of leverage for a company whose
assets are primarily income-producing real estate. The total market
capitalization of the Company, however, is more variable than book value, and
does not necessarily reflect the fair market value of the underlying assets of
the Company at all times. Although the Company considers factors other than
total market capitalization in making decisions regarding the incurrence of
indebtedness (such as the purchase price of properties to be acquired with
debt financing, the estimated market value of such properties upon refinancing
and the ability of particular properties and the Company as a whole to
generate cash flow to cover expected debt service), there can be no assurance
that the ratio of indebtedness to total market capitalization (or to any other
measure of asset value) will be consistent with the expected level of
distributions to the Company's stockholders.

The Board of Directors has adopted a policy of limiting the Company's
indebtedness to approximately 50% of its total market capitalization, but the
organizational documents of the Company do not contain any limitation on the
amount or percentage of indebtedness, funded or otherwise, that the Company
may incur. In addition, the Company may from time to time modify its debt
policy in light of then current economic conditions, relative costs of debt
and equity capital, market values of its properties, general conditions in the
market for debt and equity securities, fluctuations in the market price of its
Common Stock, growth and acquisition opportunities, the Company's continued
REIT qualification requirements and other presently unknown factors which may
arise in the future which, in the judgment of the Board of Directors, require
a revision in such policy. Accordingly, the Company may increase or decrease
its debt to market capitalization ratio beyond the limits described above. See
"Risk Factors--No Limitation on Debt."

119
<PAGE>

To the extent that the Board of Directors decides to obtain additional
capital, the Company may raise such capital through additional equity
offerings (including offerings of senior or convertible securities and
preferred stock), sales of investments, bank and other institutional
borrowings, the issuance of debt securities (which may be convertible into or
exchangeable for shares of Common Stock or be accompanied by warrants to
purchase shares of Common Stock) or retention of cash flow (subject to
provisions in the Code concerning taxability of undistributed REIT income), or
a combination of these methods. In the event that the Board of Directors
determines to raise additional equity capital, the Board has the authority,
without stockholder approval, to issue additional shares of Common Stock or
other capital stock (including securities senior to the Common Stock) of the
Company in any manner, and on such terms and for such consideration, it deems
appropriate, including in exchange for property. Existing stockholders have no
preemptive right to purchase shares issued in any offering, and any such
offering might cause a dilution of a stockholder's investment in the Company.
As long as the Operating Partnership is in existence, the net proceeds of the
sale of Common Stock by the Company will be contributed to the Operating
Partnership as a contribution to capital in exchange for a number of Units in
the Operating Partnership equal to the number of shares of Common Stock sold
by the Company. The Company presently anticipates that any additional
borrowings would be made by the Operating Partnership, although the Company
might incur indebtedness, the proceeds of which would be re-loaned to the
Operating Partnership on the same terms and conditions as are applicable to
the Company's borrowing of such funds. See "Partnership Agreement of the
Operating Partnership--Capital Contribution."

Borrowings may be unsecured or may be secured by any or all of the assets of
the Company, the Operating Partnership or any existing or new property-owning
partnership and may have full or limited recourse to all or any portion of the
assets of the Company, the Operating Partnership or any existing or new
property-owning partnership. Indebtedness incurred by the Company may be in
the form of bank borrowings, purchase money obligations to the sellers of the
properties, publicly or privately placed debt instruments or financing from
institutional investors or other lenders, any of which may be recourse to all
or any part of the property of the Company or may be limited to the particular
property for which the indebtedness relates. The Company does not have a
policy limiting the number or amount of mortgages or interests which may be
placed on any particular property. In addition, the proceeds from any
borrowings by the Company may be used for working capital, to refinance
existing indebtedness, to finance the acquisition, expansion or development of
properties and for the payment of distributions.

The Board of Directors also has the authority to cause the Operating
Partnership to issue additional Units in any manner (and on such terms and for
such consideration) as it deems appropriate, including in exchange for
property. See "Partnership Agreement of the Operating Partnership--Issuance of
Additional Units."

In the future, the Company may seek to extend, expand, reduce or renew the
Mortgage Loans, the amount available under the Credit Facility, or obtain new
credit facilities or lines of credit, subject to its general policy of debt
capitalization. Future mortgage loans, credit facilities and lines of credit
may be used for the purpose of making acquisitions or capital improvements,
providing working capital or meeting the taxable income distribution
requirements for REITs under the Code if the Company has taxable income
without receipt of cash sufficient to enable the Company to meet such
distribution requirements. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Liquidity and Capital
Resources" and "Description of Indebtedness."

WORKING CAPITAL RESERVES

The Company will maintain working capital reserves (and when not sufficient,
access to borrowings) in amounts that the Board of Directors determines from
time to time to be adequate to meet normal contingencies in connection with
the operation of the Company's business and investments. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Liquidity and Capital Resources."

CONFLICT OF INTEREST POLICIES

Directors and officers of the Company may be subject to certain conflicts of
interest in fulfilling their responsibilities to the Company. The Company has
adopted certain policies designed to minimize potential conflicts of interest.

120
<PAGE>

Terms of Transfers. The terms of the transfers of certain of the Properties
to the Operating Partnership by the Unitholders who are members of the Kilroy
Group and the terms of each of the option agreements relating to the Option
Properties, were not determined through arm's length negotiations. Partners
and affiliates of the Kilroy Group who are directors and officers of the
Company had a substantial economic interest in the entities transferring the
Properties and granting the options. Consequently, such directors and officers
may be subject to a conflict of interest with respect to their obligations as
management of the Company to enforce the terms of the agreements relating to
such transfers, including the indemnification provisions thereof. However, a
majority of the Independent Directors must approve any transactions between
the Company and members of the Kilroy Group, including the enforcement of the
terms of the transfers. See "Risk Factors--Conflicts of Interest" and
"Management."

Sale or Refinancing of Certain of the Properties. The sale of certain of the
Properties may cause adverse tax consequences to members of the Kilroy Group,
as compared to the effects on the Company. In addition, a significant
reduction in debt encumbering such Properties could cause adverse tax
consequences to the members of the Kilroy Group, as compared to the effects on
the holders of Units or shares of Common Stock. As a result, certain officers
and directors who are members of the Kilroy Group might not favor such a sale
of such Properties or a significant reduction in debt even though such sale or
debt reduction could be beneficial to the Company. The decision as to whether
to proceed with any such sale or debt reduction would be made by the Board of
Directors, subject to the obligation of the Operating Partnership to use its
commercially reasonable efforts to cooperate with the limited partners to
minimize any taxes payable in connection with any repayment, refinancing,
replacement or restructuring of indebtedness, or any sale, exchange or any
other disposition of assets, of the Operating Partnership. In addition, the
Partnership Agreement provides that if the limited partners own at least 5% of
the outstanding Units (including Units held by the Company), the Company shall
not, without the prior consent of a majority of the limited partners, prior to
January 31, 2004, sell the Office Property located at 2260 E. Imperial
Highway, at Kilroy LAX, other than incident to a merger or sale of
substantially all of the Company's assets. See "Partnership Agreement of the
Operating Partnership--Transferability of Interests" and "--Certain Limited
Partner Approval Rights."

Noncompetition Agreements. John B. Kilroy, Sr. has agreed, during the term
of his service as a member of the Board of Directors, not to conduct, directly
or indirectly, any property development, acquisition or management activities
with respect to office and industrial property in greater Southern California
or in any other market in which the Company owns, develops or manages
property. John B. Kilroy, Sr. is not restricted, however, from continuing to
own, manage, lease, transfer and exchange certain other existing real estate
investments owned by him including, without limitation, certain properties
described under "Business and Properties--Option Properties."

John B. Kilroy, Jr. has agreed, during the term of his employment agreement
and for one year thereafter (unless terminated by the Company without "cause"
or by John B. Kilroy, Jr. for "good reason" or following a "change of
control," as such terms are defined in his employment agreement), and for so
long as he is a member of the Board of Directors, not to conduct, directly or
indirectly, any property development, acquisition, sale or management
activities in any market, or own interests in real property which are
competitive, directly or indirectly, with any business carried on by the
Company. Notwithstanding the foregoing, John B. Kilroy, Jr. is not restricted
from continuing to own, manage, lease, transfer and exchange certain existing
real estate investments owned by him described under the caption "Business and
Properties--Option Properties" or owning interests in real property not
competitive with the Company. See "Management--Employment Agreements."

In addition, with respect to the property located at Calabasas Park Centre,
each of John B. Kilroy, Sr. and John B. Kilroy, Jr. has agreed to be limited
solely to activities related to the marketing, entitlement, sale, transfer and
exchange of such properties. Such properties are being actively marketed for
sale and are expected to be sold in the ordinary course of business. John B.
Kilroy, Sr. and John B. Kilroy, Jr. each spend an immaterial amount of time in
connection with the sale of such properties. In addition, each has agreed not
to sell such properties located at Calabasas Park Centre to a real estate
investment trust with an existing portfolio of office or industrial properties
unless first offered to the Company on the same economic terms.

121
<PAGE>

License Agreement. KI and the Unitholders who are members of the Kilroy
family have entered into a license agreement (the "License Agreement")
pursuant to which such Unitholders have granted to the Company the
nonexclusive right to use the Kilroy name in connection with the acquisition,
development, leasing and management of commercial properties. Pursuant to the
terms of the License Agreement, each of the Unitholders retains the right to
use the Kilroy name for commercial endeavors, including in connection with
real estate transactions. Such activities are subject to the limitations set
forth in the agreements described above in the subsection "--Noncompetition
Agreements."

Policies Applicable to All Directors. Under the Articles of Incorporation
and Maryland law, a contract or transaction between the Company and any of its
directors or between the Company and any other corporation, firm or other
entity in which any of its directors is a director, officer, stockholder,
member or partner or has a material financial interest is not void or voidable
solely because of such interest if (i) the contract or transaction is
approved, after disclosure of the interest, by the affirmative vote of a
majority of the disinterested directors, or by the affirmative vote of a
majority of the votes cast by disinterested stockholders, or (ii) the contract
or transaction is established to have been fair and reasonable to the Company.

The Articles of Incorporation and Bylaws provide that a majority of the
Board of Directors must be Independent Directors. See "Certain Provisions of
Maryland Law and of the Articles of Incorporation and Bylaws--The Board of
Directors."

OTHER POLICIES

The Company operates in a manner that does not subject it to regulation
under the Investment Company Act of 1940. The Company does not intend (i) to
invest in the securities of other issuers (other than the Operating
Partnership and the Services Company) for the purpose of exercising control
over such issuer, (ii) to underwrite securities of other issuers or (iii) to
trade actively in loans or other investments.

The Board of Directors has the authority, without stockholder approval, to
issue additional shares of Common Stock or other securities and to repurchase
or otherwise reacquire shares of Common Stock or any other securities in the
open market or otherwise and may engage in such activities in the future. The
Company may, under certain circumstances, purchase shares of Common Stock in
the open market, if such purchases are approved by the Board of Directors. The
Board of Directors has no present intention of causing the Company to
repurchase any of the shares of Common Stock, and any such action would be
taken only in conformity with applicable federal and state laws and the
requirements for qualifying as a REIT under the Code and the Treasury
Regulations. To date, the Operating Partnership has issued 165,102 additional
limited partnership Units exchangeable into shares of Common Stock in exchange
for certain real property interests and the Operating Partnership may issue
additional Units, and the Company may issue additional shares of Common Stock,
in the future. The Company expects to issue shares of Common Stock to
Unitholders upon exercise of their exchange rights in the Partnership
Agreement. The Company has not made loans to other entities or persons,
including its officers and directors. The Company may in the future make loans
to joint ventures in which it participates in order to meet working capital
needs. The Company has not engaged in trading, underwriting or agency
distribution or sale of securities of other issuers other than the Operating
Partnership, nor has the Company invested in the securities of other issuers
other than the Operating Partnership and the Services Company for the purposes
of exercising control, and does not intend to do so.

At all times, the Company intends to make investments in such a manner as to
be consistent with the requirements of the Code for the Company to qualify as
a REIT unless, because of changing circumstances or changes in the Code (or in
Treasury Regulations), the Board of Directors determines that it is no longer
in the best interests of the Company to qualify as a REIT and such
determination is approved by the affirmative vote of holders owning at least
two-thirds of the shares of the Company's capital stock outstanding and
entitled to vote thereon.

MANAGEMENT

DIRECTORS AND EXECUTIVE OFFICERS

The Board of Directors consists of five members, including a majority of
directors who are Independent Directors. Directors of the Company are divided
into three classes serving staggered three-year terms (except initial terms
expiring in 1998 and 1999) with directors serving until the election and
qualification of their successors. The first annual meeting of stockholders of
the Company after the IPO will be held in 1998. See "Certain Provisions of

COMMITTEES OF THE BOARD OF DIRECTORS

Audit Committee. The Board of Directors established an audit committee (the
"Audit Committee") to make recommendations concerning the engagement of
independent public accountants, review with the independent public accountants
the scope and results of the audit engagement, approve professional services
provided by the independent public accountants, review the independence of the
independent public accountants, consider the range of audit and non-audit fees
and review the adequacy of the Company's internal accounting controls. The
Audit Committee consists of two Independent Directors, Messrs. Matthew J.
Hart, the Chairman, and William P. Dickey.

Independent Committee. The Board of Directors established an independent
committee (the "Independent Committee") which consists solely of the
Independent Directors, Messrs. Dale F. Kinsella, the chairman, Matthew J. Hart
and William P. Dickey. The Independent Committee is established to approve
transactions between the Company and John B. Kilroy, Sr. or John B. Kilroy,
Jr. and their respective affiliates.

Executive Committee. The Board of Directors established an executive
committee (the "Executive Committee"). Subject to the Company's conflict of
interest policies, the Executive Committee is granted the authority to acquire
and dispose of real property and the authority to execute, on behalf of the
Board of Directors, certain contracts and agreements, including those related
to the borrowing of money by the Company (and, consistent with the Partnership
Agreement, to cause the Operating Partnership to take such actions). The
Executive Committee consists of John B. Kilroy, Sr., the chairman, John B.
Kilroy, Jr. and one Independent Director, Dale F. Kinsella.

Executive Compensation Committee. The Board of Directors formed an executive
compensation committee (the "Executive Compensation Committee") to establish
remuneration levels for executive officers of the Company and implementation
of the Stock Incentive Plan (as defined) and any other incentive programs. The
Executive Compensation Committee consists of two Independent Directors,
Messrs. William P. Dickey, the chairman, and Matthew J. Hart.

The Board of Directors may from time to time establish certain other
committees to facilitate the management of the Company.

COMPENSATION OF DIRECTORS

The Company currently pays its Independent Directors (as defined) annual
compensation of $12,000 for their services. In addition, Independent Directors
receive $1,000 for each committee meeting chaired by such director.
Independent Directors also are reimbursed for reasonable expenses incurred to
attend director and committee meetings. An "Independent Director" is a
director who is not an employee, officer or affiliate of the Company or a
subsidiary or a division thereof, or a relative of a principal executive
officer, or who is not an individual member of an organization acting as an
advisor, consultant or legal counsel, receiving compensation on a continuing
basis from the Company in addition to director's fees. Officers of the Company
who are directors will not be paid any director's fees. Each Independent
Director receives, upon initial election to the Board of Directors, an option
to purchase 10,000 shares of Common Stock which vests pro rata in annual
installments over a three-year period. Each Independent Director receives an
option to purchase 1,000 shares of Common Stock on each anniversary of his
election to the Board of Directors, which options also vests pro rata in
annual installments over a three-year period. In addition, on January 31,
1997, John B. Kilroy, Sr., who is not an Independent Director, received an
option to purchase 15,000 shares of Common Stock which vests over a three-year
period. All stock options will be issued pursuant to the Stock Incentive Plan
at an exercise price equal to or greater than the fair market value of the
Common Stock at the date of grant.

EXECUTIVE COMPENSATION

Since the Company has no operating history prior to 1997, meaningful
individual compensation information for executive officers is not available
for prior periods. The compensation table below sets forth the annual base
salary rates and other compensation to be paid in 1997 to the Chief Executive
Officer and the Company's other executive officers who are expected to have a
total annual salary and bonus in excess of $100,000. The Company has entered
into employment agreements with each of its executive officers as described
below. See "--Employment Agreements."

1997.
(2) Options to purchase an aggregate of 1,185,000 shares of Common Stock have

Plan. See "--Stock Incentive Plan."
(3) Under the terms of each executive officer's respective employment
agreement, each executive officer is entitled to receive an annual bonus
in an amount up to 100% of such executive officer's base salary. The
amount of any such bonus will be determined by the Executive Compensation

(4) Pursuant to Mr. Moran's employment agreement, concurrent with the
consummation of the IPO, he received 100,000 restricted shares of Common
Stock under the Stock Incentive Plan with an aggregate value at January
31, 1997, the date of issuance, of $2.3 million against the payment of
$1,000 therefor. The restricted shares of Common Stock vest in equal
annual installments pro rata over a five-year period, subject to certain

EMPLOYMENT AGREEMENTS

Each of John B. Kilroy, Jr., Jeffrey C. Hawken, Richard E. Moran Jr.,
Campbell Hugh Greenup and Tyler H. Rose entered into an employment agreement
with the Company which became effective on January 31, 1997 or, in the case of
Mr. Rose, the commencement of his employment. The employment agreements will
have an initial term of three years and are subject to automatic one-year
extensions following the expiration of the initial term. The employment
agreements provide for annual base compensation in the amounts set forth in
the Executive Compensation table with the amount of any bonus to be determined
by the Executive Compensation Committee, up to 100% of the applicable annual
base compensation. Under the terms of his employment agreement, Mr. Moran was
paid a bonus of $200,000 on January 31, 1997. Mr. Moran's bonus was an
obligation of, and was paid by, the principals of KI.

The employment agreements entitle the executives to participate in the Stock
Incentive Plan (each executive was initially allocated the number of stock
options and/or restricted shares of Common Stock set forth in the Executive
Compensation table) and to receive certain other insurance benefits. The
employment agreements also provide that in the event of death, the executive's
estate will receive monthly payments of the executive's annual salary, plus
one-twelfth of any bonus to be received, for a period equal to the lesser of
the term remaining under the employment agreement or one year. In addition, in
the event of a termination by the Company without "cause," a termination of
employment resulting from "disability," a termination by the executive for
"good reason," or, in the case of Mr. Kilroy and Mr. Moran, a termination
pursuant to a "change of control" of the Company (as such terms are defined in
the respective employment agreements), the terminated executive will be
entitled to (i) severance (the "Severance Amount") and (ii) continued receipt
of certain benefits including medical insurance, life and disability insurance
and the receipt of other customary benefits established by the Company for its
executive employees for two years following the date of termination
(collectively, the "Severance Benefits"). The Severance Amount is equal to the
sum of two times the executive's average annual base compensation and two
times the highest annual bonus received during the preceding 36-month period.
"Disability" means a physical or mental disability or infirmity which, in the
opinion of a physician selected by the Board of Directors, renders the
executive unable to perform his duties for six consecutive months or for
shorter periods aggregating 180 business days in any 12-month period (but only
to the extent that such definition does not violate the Americans with
Disabilities Act). "Cause," as defined under the terms of the respective
employment agreements, means (a) the executive's conviction for commission of
a felony or a crime involving moral turpitude, (b) the executive's willful
commission of any act of theft, embezzlement or misappropriation against the
Company, or (c) the executive's willful and continued failure to substantially
perform the executive's duties (other than such failure resulting from the
executive's incapacity due to physical or mental illness), which is not
remedied within a reasonable time. "Good reason" means (a) the Company's
material breach of any of its obligations under the employment agreement
(subject to certain notice and cure provisions) or (b) any removal of the
executive from one or more of the appointed offices or any material alteration
or diminution in the executive's authority, duties or responsibilities,
without "cause" and without the executive's prior written

127
<PAGE>

consent. "Change of Control" means (a) the event by which the individuals
constituting the Board of Directors as of the date of the IPO cease for any
reason to constitute at least a majority of the Board of Directors; provided,
however, that if the election, or nomination for election by the Company's
stockholders of any new director was approved by a vote of at least a majority
of the members of the original Board of Directors, such new director shall be
considered a member of the original Board of Directors, (b) an acquisition of
any voting securities of the Company by any "person" (as the term"person" is
used for purposes of Section 13(d) or Section 14(d) of the Securities Exchange
Act of 1934, as amended (the "Exchange Act")) immediately after which such
person has "beneficial ownership" (within the meaning of Rule 13d-3
promulgated under the Exchange Act) of 20% or more of the combined voting
power of the Company's then outstanding voting securities unless such
acquisition was approved by a vote of at least one more than a majority of the
original Board of Directors, or (c) approval by the stockholders of the
Company of (i) a merger, consolidation, share exchange or reorganization
involving the Company, unless the stockholders of the Company, immediately
before such merger, consolidation, share exchange or reorganization, own,
directly or indirectly immediately following such merger, consolidation, share
exchange or reorganization, at least 80% of the combined voting power of the
outstanding voting securities of the corporation that is the successor in such
merger, consolidation, share exchange or reorganization in substantially the
same proportion as their ownership of the voting securities immediately before
such merger, consolidation, share exchange or reorganization; (ii) a complete
liquidation or dissolution of the Company; or (iii) an agreement for the sale
or other disposition of all or substantially all of the assets of the Company.

STOCK INCENTIVE PLAN

The Company established the 1997 Stock Option and Incentive Plan (the "Stock
Incentive Plan") to enable executive officers, key employees and directors of
the Company, the Operating Partnership and the Services Company to participate
in the ownership of the Company. The Stock Incentive Plan is designed to
attract and retain executive officers, other key employees and directors of
the Company, the Operating Partnership and the Services Company and to provide
incentives to such persons to maximize the Company's cash flow available for
distribution. The Stock Incentive Plan provides for the award to such
executive officers and employees of the Company, the Operating Partnership and
the Services Company (subject to the Ownership Limit, or such other limit as
provided in the Articles of Incorporation or as otherwise permitted by the
Board of Directors) of a broad variety of stock-based compensation
alternatives such as nonqualified stock options, incentive stock options,
restricted stock and stock appreciation rights, and provides for the grant to
Independent Directors and directors of the Services Company (subject to the
Ownership Limit, or such other limit as provided in the Articles of
Incorporation or as otherwise permitted by the Board of Directors) of
nonqualified stock options.

Stock Options. As of July 31, 1997, the Company issued to certain officers,
directors and key employees of the Company, the Operating Partnership and the
Services Company options to purchase, subject to the Ownership Limit, or such
other limit as provided in the Articles of Incorporation or as otherwise
permitted by the Board of Directors, 1,185,000 shares of Common Stock pursuant
to the Stock Incentive Plan. The term of each of such option is ten years from
the date of grant. Each such option vests 33 1/3% per year over three years
beginning on the first anniversary date of the grant and is exercisable at a
price per share equal to the fair market value per share of Common Stock on
the date of the grant. The following table below sets forth the allocation of
the options to such persons that had been issued as of July 31, 1997.

An additional 215,000 shares of Common Stock have been reserved for issuance
under the Stock Incentive Plan. There is no limit on the number of awards that
may be granted to any one individual so long as the (i) aggregate fair market
value (determined at the time of grant) of shares with respect to which an
incentive stock option is first exercisable by an optionee during any calendar
year cannot exceed $100,000, (ii) the grant does not violate the Ownership
Limit or cause the Company to fail to qualify as a REIT for federal income tax
purposes and (iii) the maximum number of shares of Common Stock for which
stock options and stock appreciation rights may be issued during any fiscal
year to any participant in the Stock Incentive Plan shall not exceed 300,000.
See"Description of Capital Stock--Restrictions on Ownership and Transfer." To
the extent permitted by the foregoing, the option grants shown in the above
table will include incentive stock options.

Restricted Stock. Restricted stock may be sold to participants at various
prices (but not below par value) and are subject to such restrictions as may
be determined by the Executive Compensation Committee. Restricted stock,
typically, may be repurchased by the Company at the original purchase price if
the conditions or restrictions are not met. In general, restricted stock may
not be sold, or otherwise transferred or hypothecated, until restrictions are
removed or expire. Purchasers of restricted stock have voting rights and
receive distributions prior to the time when the restrictions lapse. The
Company issued 100,000 restricted shares of Common Stock reserved for issuance
under the Stock Incentive Plan, to Richard E. Moran Jr. on January 31, 1997.

Administration of the Stock Incentive Plan. The Stock Incentive Plan is
administered by the Board of Directors and/or the Executive Compensation
Committee. No person is eligible to serve on the Executive Compensation
Committee unless such person is then an Independent Director. The Committee
has complete discretion to determine (subject to (a) the Ownership Limit
contained in the Articles of Incorporation of the Company and (b) a limit
against granting options or stock appreciation rights for more than 300,000
shares to any person in any fiscal year) which eligible individuals are to
receive option or other stock grants, the number of shares subject to each
such grant, the status of any granted option as either an incentive option or
a non-qualified stock option under the federal tax laws, the exercise schedule
to be in effect for the grant, the maximum term for which any granted option
is to remain outstanding and subject to the specific terms of the Stock
Incentive Plan, any other terms of the grant.

Eligibility. All employees of the Company may, at the discretion of the
Executive Compensation Committee, be granted incentive and non-qualified stock
options to purchase shares of Common Stock at any exercise price not less than
100% of the fair market value of such shares on the grant date. Directors of
the Company, employees of the Operating Partnership, employees and directors
of the Services Company, consultants and other persons who are not regular
salaried employees of the Company are not eligible to receive incentive stock
options, but are eligible to receive non-qualified stock options. In addition,
all employees and consultants of the Company, the Operating Partnership and
the Services Company are eligible for awards of restricted stock and grants of
stock appreciation rights.

Number of Shares Subject to Stock Incentive Plan. The Company has reserved
up to 1,500,000 shares of Common Stock for issuance pursuant to the Stock
Incentive Plan, 100,000 of which was issued, and options covering 1,185,000 of
which were granted, under the Stock Incentive Plan.

Purchase Price of Shares Subject to Options. The price of the shares of
Common Stock subject to each option shall be set by the Executive Compensation
Committee; provided, however, that the price per share of an option shall be
not less than 100% of the fair market value of such shares on the date such
option is granted; provided, further, that, in the case of an incentive stock
option, the price per share shall not be less than 110% of the fair market
value of such shares on the date such option is granted in the case of an
individual then owning (within the meaning of Section 424(d) of the Code) more
than ten percent of the total combined voting power of all classes of stock of
the Company, any subsidiary or any parent corporation ("greater than 10%
stockholders").

Non-Assignability. Options may be transferred only by will or by the laws of
descent and distribution. During a participant's lifetime, options are
exercisable only by the participant.

129
<PAGE>

Terms and Exercisability of Options. Unless otherwise determined by the
Board of Directors or the Executive Compensation Committee, all options
granted under the Stock Incentive Plan are subject to the following
conditions: (i) options will be exercisable in installments, on a cumulative
basis, at the rate of thirty-three and one-third percent (33 1/3%) each year
beginning on the first anniversary of the date of the grant of the option,
until the options expire or are terminated, and (ii) following an optionee's
termination of employment, the optionee shall have the right to exercise any
outstanding vested options for a specified period.

Options are not assignable or transferable by the optionee except by will or
the laws of inheritance following the optionee's death. The optionee has no
stockholder rights with respect to the shares subject to his or her
outstanding options until such options are exercised and the purchase price is
paid for the shares.

To the extent that the aggregate fair market value of stock with respect to
which "incentive stock options" (within the meaning of Section 422 of the
Code, but without regard to Section 422(d) of the Code) are exercisable for
the first time by an optionee during any calendar year (under the Stock
Incentive Plan and all other incentive stock option plans of the Company, any
subsidiary and any parent corporation) exceeds $100,000, such options shall be
taxed as non-qualified stock options. The rule set forth in the preceding
sentence shall be applied by taking options into account in the order in which
they were granted. For this purpose, the fair market value of stock shall be
determined as of the time that the option with respect to such stock is
granted.

Options are exercisable in whole or in part by written notice to the
Company, specifying the number of shares being purchased and accompanied by
payment of the purchase price for such shares. The option price may be paid:
(i) in cash or by certified or cashier's check payable to the order of the
Company, (ii) by delivery of shares of Common Stock already owned by, and in
the possession of, the optionee or (iii) if authorized by the Board of
Directors or the Executive Compensation Committee or if specified in the
option agreement for the option being exercised, by a recourse promissory note
made by the optionee in favor of the Company or through installment payments
to the Company.

On the date the option price is to be paid, the optionee (or his or her
successor) must make full payment to the Company of all amounts that must be
withheld by the Company for federal, state or local tax purposes.

Termination of Employment; Death or Permanent Disability. If a holder of an
option ceases to be employed by the Company for any reason other than the
optionee's death or permanent disability, such optionee's stock option shall
expire three months after the date of such cessation of employment unless by
its terms it expires sooner; provided, however, that during such period after
cessation of employment, such stock option may be exercised only to the extent
it was exercisable according to such option's terms on the date of cessation
of employment. If an optionee dies or becomes permanently disabled while the
optionee is employed by the Company, such optionee's option shall expire
twelve months after the date of such optionee's death or permanent disability
unless by its terms it expires sooner. During such period after death, such
stock option may, to the extent it remains unexercised upon the date of such
death, be exercised by the person or persons to whom the optionee's rights
under such stock option are transferred under the laws of descent and
distribution.

Acceleration of Exercisability. In the event that the Company is acquired by
merger, consolidation or asset sale, each outstanding option which is not to
be assumed by the successor corporation or replaced with a comparable option
to purchase shares of the capital stock of the successor corporation will, at
the election of the Board of Directors (or if so provided in an option or
other agreement with an optionee), automatically accelerate in full.

Adjustments. In the event any change is made to the Common Stock issuable
under the Stock Incentive Plan by reason of any recapitalization, stock
dividend, stock split, combination of shares, exchange of shares or other
change in corporate structure effected without the Company's receipt of
consideration, appropriate adjustment will be made to (i) the maximum number
and class of shares issuable under the Stock Incentive Plan and (ii) the
number and/or class of shares and price per share in effect under each
outstanding option.

130
<PAGE>

Amendments to the Stock Incentive Plan. The Board of Directors may at any
time suspend or terminate the Stock Incentive Plan. The Board of Directors or
Executive Compensation Committee may also at any time amend or revise the
terms of the Stock Incentive Plan; provided that no such amendment or revision
shall, unless appropriate stockholder approval of such amendment or revision
is obtained, (i) increase the maximum number of shares which may be acquired
pursuant to options granted under the Stock Incentive Plan (except for
adjustments as described in the foregoing paragraph) or (ii) change the
minimum purchase price required under the Stock Incentive Plan.

Termination. The Stock Incentive Plan will terminate on January 31, 2007,
unless sooner terminated by the Board of Directors.

Registration Statement on Form S-8. The Company plans to file with the
Securities and Exchange Commission a Registration Statement on Form S-8
covering the restricted shares of Common Stock and the shares of Common Stock
underlying options granted under the Stock Incentive Plan.

SECTION 401(K) PLAN

The Company plans to establish the Company's Section 401(k)
Savings/Retirement Plan (the "Section 401(k) Plan") to cover eligible
employees of the Company and any designated affiliate.

It is expected that the Section 401(k) Plan will permit eligible employees
of the Company to defer up to 15% of their annual compensation, subject to
certain limitations imposed by the Code. It is further expected that the
employees' elective deferrals will immediately vest and will be non-
forfeitable upon contribution to the Section 401(k) Plan. The Company expects
to reserve the right to make matching contributions to the Section 401(k) Plan
or discretionary profit sharing contributions in the future.

INDEMNIFICATION

For a description of the limitation of liability and indemnification rights
of the Company's officers and directors, see "Certain Provisions of Maryland
Law and of the Articles of Incorporation and Bylaws--Limitation of Directors'
and Officers' Liability" and "--Indemnification Agreements."

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Certain directors and executive officers of the Company, including John B.
Kilroy, Sr. and John B. Kilroy, Jr., the Chairman of the Board of Directors
and its President and Chief Executive Officer, respectively, (or members of
their immediate families) and persons who will hold more than 5% of the
outstanding shares of Common Stock (or interests exchangeable therefor) have
direct or indirect interests in transactions with by the Company, the
Operating Partnership or the Services Company, including the transfer of
certain Properties to the Operating Partnership by the Unitholders in
connection with the Formation Transactions, the grant of options with respect
to the Option Properties and, if exercised, the purchase by the Company of one
or more of the Option Properties from the respective Unitholders, the
repayment of certain indebtedness encumbering the Properties contributed by
the Kilroy Group to the Operating Partnership in connection with the Formation
Transactions and the performance of management and leasing activities by the
Operating Partnership and certain development and other activities by the
Services Company at the Option Properties. See "Formation and Structure of the
Company--Formation Transactions." In addition, John B. Kilroy, Sr. contributed
$1,000 to the Company in exchange for an aggregate of 50 shares of Common
Stock which were subsequently repurchased by the Company, and on January 31,
1997, John B. Kilroy, Jr. and John B. Kilroy, Sr. each contributed cash to the
Services Company, which represents a 5.0% economic interest in the Services
Company. See the Combined Financial Statements and the notes thereto contained
elsewhere in this Prospectus.

PARTNERSHIP AGREEMENT

On January 31, 1997, Kilroy Realty Corporation entered into the Partnership
Agreement of the Operating Partnership with the various limited partners of
the Operating Partnership. See "Partnership Agreement of the Operating

On January 31, 1997, KI assigned to the Operating Partnership all of its
interest as a tenant in a lease with a partnership affiliated with certain
Unitholders covering the space that was serving as the headquarters of KI at
Kilroy LAX in El Segundo, California. The Company, the Operating Partnership
and the Services Company occupy such space, with the Company and the Services
Company subleasing some of such space from the Operating Partnership and
paying rent to the Operating Partnership therefor, at rates which the Company
believes are equal to the fair rental value of the space.

Pursuant to management agreements, the Operating Partnership is providing
management and leasing services, and the Services Company is providing
development services, with respect to the Option Properties, each of which is
beneficially owned and controlled by John B. Kilroy, Sr. and John B. Kilroy,
Jr., for fees equivalent to the fair market value of such services. See
"Business and Properties--Option Properties."

OPTIONS TO PURCHASE CERTAIN PROPERTIES

In connection with the formation of the Company, the Company entered into
certain option agreements with partnerships controlled by John B. Kilroy, Sr.
and John B. Kilroy, Jr., the Chairman of the Board of Directors, and
President, Chief Executive Officer and Director, respectively, granting to the
Operating Partnership options to acquire (i) parcels comprising an aggregate
of approximately 18 acres located at Calabasas Park Centre, in Calabasas,
California and (ii) the Sepulveda Boulevard Office Complex at the respective
purchase price for each of the properties as discussed below. The option for
Calabasas Park Centre is exercisable on or before January 31, 1998. The option
for the Sepulveda Boulevard Office Complex is exercisable on or before January
31, 2004. The purchase price for each of the properties is payable in cash;
provided, however, that if the option for the office complex in El Segundo is

<PAGE>

Pursuant to the terms of the applicable option agreement, the purchase price
for the parcels located at Calabasas Park Centre will be equal to the lower of
(i) a third-party offer or (ii) the total accumulated costs, as of the date
such option is exercised, in connection with the acquisition of rights with
respect to, and the entitlement and development of such property, including,
without limitation, property taxes, predevelopment and entitlement costs and
fees, and related bond financing costs.

In addition, in connection with the Formation Transactions, the Company
incurred certain expenses on behalf of KI, including the payment of $700,000
of interest in connection with the repayment of an outstanding loan. All
amounts payable to the Company from KI have been paid in full. The highest
amount of such receivables outstanding during the period beginning February 1,
1997 was approximately $1.3 million.

FORMATION AND STRUCTURE OF THE COMPANY

Kilroy Realty Corporation was formed in September 1996 and the Operating
Partnership was formed in October 1996. The Services Company was formed in
January 1997.

FORMATION TRANSACTIONS

As of the consummation of the IPO, the Company and certain of the
Unitholders who are members of the Kilroy Group engaged in the Formation
Transactions designed to enable the Company to continue and expand the real
estate operations of the Kilroy Group, to facilitate the IPO, to enable the
Company to qualify as a REIT for federal income tax purposes commencing with
its taxable year ending December 31, 1997 and to preserve certain tax
advantages for certain Unitholders of the Properties. The Formation
Transactions were as follows:

. Pursuant to the Omnibus Agreement, the Operating Partnership required
the contribution to the Operating Partnership of all of the Kilroy
Group's interests in the Properties owned by them immediately prior to
the IPO, the assets used to conduct the leasing, management and
development activities (principally office equipment) and the assignment
of contract rights in connection with development opportunities at
Kilroy Airport Center Long Beach. Pursuant to the terms of the Omnibus
Agreement, the Operating Partnership acquired the Existing Properties
and the other assets from the Kilroy Group in exchange for limited
Partnership Units. Upon completion of the IPO, the limited Partnership
Units received by the Kilroy Group constituted in the aggregate an
approximately 15.5% limited partnership interest in the Operating
Partnership.

. John B. Kilroy, Sr. and John B. Kilroy, Jr. acquired all of the voting
common stock of the Services Company for the aggregate purchase price of
$5,275 in cash (representing 5.0% of its economic value), and the
Operating Partnership acquired all of the non-voting preferred stock of
the Services Company (representing 95.0% of its economic value).

. The Company contributed the net proceeds from the IPO and the issuance
of 100,000 restricted shares of Common Stock (approximately $302.8
million in the aggregate) to the Operating Partnership in exchange for
an 84.5% general partner interest in the Operating Partnership.

. The Company, through the Operating Partnership, borrowed approximately
$84.0 million principal amount of long-term financing and $12.0 million
principal amount of short-term debt pursuant to the Mortgage Loans.

. The Operating Partnership applied the IPO net proceeds and the Mortgage
Loans toward the repayment of existing mortgage indebtedness on certain
of the Properties, the purchase of certain properties and payment of its
expenses arising in connection with the IPO and the Mortgage Loans.

. Certain employees of KI became employees of the Company, the Operating
Partnership and/or the Services Company, including John B. Kilroy, Jr.,
the President and Chief Executive Officer of KI, three other executive
officers (Mr. Jeffrey Hawken, Executive Vice President and Chief
Operating Officer, Mr. Richard E. Moran Jr., Executive Vice President,
Chief Financial Officer and Secretary, and Mr. Campbell Hugh Greenup,
General Counsel) who are not Unitholders and 43 other operating and
administrative employees.

. On January 31, 1997, the Company entered into option agreements with
partnerships controlled by John B. Kilroy, Sr. and John B. Kilroy, Jr.
granting to the Operating Partnership the right to acquire (i) the
approximately 18 undeveloped acres located at Calabasas Park Centre for
cash and (ii) the Sepulveda Boulevard Office Complex for cash (or for
Units after January 31, 1998 at the election of the seller), and in each
case pursuant to the other terms of the respective option agreement. See
"Business and Properties--Option Properties--Calabasas Park Centre"
and"--North Sepulveda Boulevard, El Segundo" for a discussion of the
purchase price and other material terms of each Option Agreement.

135
<PAGE>

. The Operating Partnership or the Services Company entered into
Management Agreements with respect to each of the Option Properties.
Pursuant to the terms of each of the Management Agreements, the
Operating Partnership or the Services Company, as applicable, has
exclusive control and authority (subject to an operating budget approved
by the owners of each property) over each of the Option Properties for a
term of 24 months. If any of the Option Properties are sold during the
term of the Management Agreements, then either party may terminate the
respective Management Agreement with respect to the property being sold
upon 30 days' prior written notice. In consideration of the services
provided under the Management Agreements, the Company receives a monthly
property management fee as well as any applicable leasing commissions.
See "Business and Properties--Option Properties."

Upon completion of the Formation Transactions and the IPO, the Company owned
14,428,367 Units, which represented an approximately 84.5% economic interest
in the Operating Partnership, and the Kilroy Group owned 2,652,374 Units,
which represented the remaining approximately 15.5% economic interest in the
Operating Partnership. The Company is the sole general partner and retains
management control over the Operating Partnership.

The Unitholders who are members of the Kilroy Group have the opportunity
after January 31, 1999 to have their Units redeemed by the Operating
Partnership at the request of the Unitholder for cash (based on the fair
market value of an equivalent number of shares of Common Stock at the time of
such redemption) or, at the Company's option, it may exchange Units for shares
of Common Stock on a one-for-one basis, subject to certain anti-dilution
adjustments and the obligation of certain of the Unitholders to indemnify the
Company in connection with the Formation Transactions; provided, however, that
if the Company does not elect to exchange such Units for shares of Common
Stock, a Unitholder that is a corporation or limited liability company may
require the Company to issue shares of Common Stock in lieu of cash, subject
to the Ownership Limit or such other limit as provided in the Articles of
Incorporation, as applicable. Under certain circumstances, 50% of the Units
received by John B. Kilroy, Sr., John B. Kilroy, Jr. and KI may be redeemed
prior to January 31, 1999 in connection with the obligation of such
Unitholders to indemnify the Company in connection with the Formation
Transactions.

ADVANTAGES AND DISADVANTAGES OF THE FORMATION TRANSACTIONS TO UNAFFILIATED
STOCKHOLDERS

The advantages of the Formation Transactions to unaffiliated stockholders of
the Company included their ability to participate in the cash flow of the
Properties through their ownership in the Company and in all future office and
industrial property acquisitions and development by the Company. The
disadvantages of such transactions to unaffiliated stockholders of the Company
included the impact of shares available for future sale and immediate and
substantial dilution in the tangible book value per share, and the lack of
arm's length negotiations to determine the terms of the transfers of the
Existing Properties to the Company and the Operating Partnership and the terms
of the option agreements relating to the Option Properties.

BENEFITS OF THE FORMATION TRANSACTIONS TO THE KILROY GROUP

The Kilroy Group realized certain benefits as a result of the IPO and the
Formation Transactions, including the following:

. improved liquidity of their interests in the Properties owned by the
Kilroy Group immediately prior to the IPO and increased diversification
of their investment;

. repayment of indebtedness in the aggregate net amount of approximately
$229.5 million resulting from the refinancing of mortgage indebtedness,
of which approximately $37.2 million was guaranteed by John B. Kilroy,
Sr., including $8.7 million which also was guaranteed by John B. Kilroy,
Jr., and the repayment of approximately $3.4 million of personal
indebtedness of John B. Kilroy, Sr.;

. an employment agreement between the Company and John B. Kilroy, Jr.
providing annual salary, incentive compensation (including Common Stock
options) and other benefits for his services as an officer of the
Company (see "Management--Employment Agreements"), and a grant of
options to purchase Common Stock to John B. Kilroy, Sr. (see
"Management--Stock Incentive Plan"); and

136
<PAGE>

. the deferral of certain tax consequences of taxable dispositions of
assets through the creation of the Operating Partnership and the direct
contribution of their interests in the Properties to the Operating
Partnership in exchange for Units.

FORMATION OF KILROY SERVICES, INC.

In January 1997, the Services Company was formed under the laws of the State
of Maryland to succeed to the development activities of the Kilroy Group. John
B. Kilroy, Sr. and John B. Kilroy, Jr. together own 100.0% of the voting
common stock of the Services Company, representing 5.0% of its economic value.
The Operating Partnership owns 100.0% of the nonvoting preferred stock of the
Services Company, representing 95.0% of its economic value. The ownership
structure of the Services Company is necessary to permit the Company to share
in the income of the activities of the Services Company and also maintain its
status as a REIT. Although the Company receives substantially all of the
economic benefit of the businesses carried on by the Services Company through
the Company's right to receive dividends through the Operating Partnership's
investment in the Services Company's nonvoting preferred stock, the Company is
not able to elect the Services Company's officer or directors and,
consequently, may not have the ability to influence the operations of the
Services Company or require the declaration of dividends. See "Risk Factors--
Risks of Development Business and Related Activities Being Conducted by the
Services Company--Adverse Consequences of Lack of Control Over the Businesses
of the Services Company."

The Services Company currently has three directors, including Campbell Hugh
Greenup, who also serves as the General Counsel of the Company; Jeffrey C.
Hawken, who also serves as the Executive Vice President and Chief Operating
Officer of the Company; and one independent director. See "Management."
Campbell Hugh Greenup serves as the Services Company's President and
Secretary, David Armanetti serves as its Vice President of Development
Services and Treasurer and Jeffrey C. Hawken serves as its Vice President and
Assistant Secretary.

FORMATION OF KILROY REALTY FINANCE, INC. AND KILROY REALTY FINANCE
PARTNERSHIP, L.P.

In January 1997, Kilroy Realty Corporation formed the Finance Company to act
as the general partner of the Finance Partnership. The Finance Partnership, a
single-purpose limited partnership, was formed in January 1997 to facilitate
borrowings under the Mortgage Loans. Kilroy Realty Corporation owns 100.0% of
the common stock of the Finance Company which owns a 1.0% general partner
interest in the Finance Partnership. The Operating Partnership owns a 99.0%
limited partner interest in the Finance Partnership. The Finance Partnership
owns legal title to the Properties secured by the Mortgage Loans.

The Finance Company currently has five directors, including John B. Kilroy,
Jr., who also serves as the President and Chief Executive Officer of the
Company; Jeffrey C. Hawken, who also serves as the Executive Vice President
and Chief Operating Officer of the Company; Richard E. Moran Jr., who also
serves as the Executive Vice President, Chief Financial Officer and Secretary
of the Company; A. Christian Krogh, who also serves as the Vice President of
Asset Management of the Company; and one independent director. See
"Management." Jeffrey C. Hawken serves as the Finance Company's President and
Secretary, A. Christian Krogh serves as its Vice President, Treasurer and
Assistant Secretary and John B. Kilroy, Jr. serves as its Vice President.

DESCRIPTION OF CAPITAL STOCK

The following summary of the terms of the Company's capital stock does not
purport to be complete and is subject to and qualified in its entirety by
reference to the Articles of Incorporation and Bylaws, copies of which are
filed as exhibits to the Registration Statement of which this Prospectus is a
part. See "Additional Information."

GENERAL

Under the Articles of Incorporation, the authorized capital stock of the
Company consists of 150,000,000 shares of Common Stock, par value $.01 per
share, and 30,000,000 shares of preferred stock, par value $.01 per share
("Preferred Stock"). Upon completion of the Offering, 24,475,000 shares of
Common Stock will be issued and outstanding excluding the 1,500,000 shares of
Common Stock which are subject to the Underwriters' over-allotment option and
2,817,476 shares of Common Stock which may be issued upon the exchange of
outstanding limited partnership Units. Upon completion of the Offering, no
shares of Preferred Stock will be issued and outstanding.

COMMON STOCK

Each outstanding share of Common Stock entitles the holder to one vote on
all matters presented to stockholders for a vote, including the election of
directors, and, except as otherwise required by law and except as provided in
any resolution adopted by the Board of Directors with respect to any other
class or series of stock establishing the designation, powers, preferences and
relative, participating, optional or other special rights and powers of such
series, the holders of such shares possess the exclusive voting power, subject
to the provisions of the Articles of Incorporation regarding the ownership of
shares of Common Stock in excess of the Ownership Limit, or such other limit
as provided in the Articles of Incorporation or as otherwise permitted by the
Board of Directors as described below. Holders of shares of Common Stock have
no conversion, exchange, sinking fund, redemption or appraisal rights and have
no preemptive rights to subscribe for any securities of the Company or
cumulative voting rights in the election of directors. All shares of Common
Stock issued and outstanding are duly authorized, fully paid and non-
assessable. Subject to the preferential rights of any other shares or series
of stock and to the provisions of the Articles of Incorporation regarding
ownership of shares of Common Stock in excess of the Ownership Limit, or such
other limit as provided in the Articles of Incorporation or as otherwise
permitted by the Board of Directors as described below, distributions are paid
to the holders of shares of Common Stock if and when authorized and declared
by the Board of Directors out of funds legally available therefor. The Company
currently makes quarterly distributions. See "Price Range of Common Stock and
Distribution History."

Under Maryland law, stockholders are generally not liable for the Company's
debts or obligations. If the Company is liquidated, subject to the right of
any holders of Preferred Stock to receive preferential distributions, each
outstanding share of Common Stock will be entitled to participate pro rata in
the assets remaining after payment of, or adequate provision for, debts and
liabilities of the Company, including debts and liabilities arising out of its
status as general partner of the Operating Partnership.

Subject to the provisions of the Articles of Incorporation regarding the
ownership of shares of Common Stock in excess of the Ownership Limit, or such
other limit as provided in the Articles of Incorporation or as otherwise
permitted by the Board of Directors described below, all shares of Common
Stock have equal distribution, liquidation and voting rights, and have no
preference or exchange rights. See "--Restrictions on Ownership and Transfer."

Under the MGCL, a Maryland corporation generally cannot dissolve, amend its
charter, merge, sell all or substantially all of its assets, engage in a share
exchange or engage in similar transactions outside the ordinary course of
business unless approved by the affirmative vote of stockholders holding at
least two-thirds of the shares entitled to vote on the matter unless a lesser
percentage (but not less than a majority of all of the votes

138
<PAGE>

entitled to be cast on the matter) is set forth in the corporation's charter.
Under the MGCL, the term "substantially all of the Company's assets" is not
defined and is, therefore, subject to Maryland common law and to judicial
interpretation and review in the context of the unique facts and circumstances
of any particular transaction. The Articles of Incorporation do not provide
for a lesser percentage in any such situation.

The Articles of Incorporation authorize the Board of Directors to reclassify
any unissued shares of capital stock into other classes or series of classes
of stock and to establish the number of shares in each class or series and to
set the preferences, conversion and other rights, voting powers, restrictions,
limitations and restrictions on ownership, limitations as to dividends or
other distributions, qualifications and terms or conditions of redemption for
each such class or series.

TRANSFER AGENT AND REGISTRAR

The transfer agent and registrar for the Common Stock is ChaseMellon
Shareholder Services.

PREFERRED STOCK

Preferred Stock may be issued from time to time, in one or more series, as
authorized by the Board of Directors. No Preferred Stock is currently issued
or outstanding. Prior to the issuance of shares of each series, the Board of
Directors is required by the MGCL and the Articles of Incorporation to fix for
each series the terms, preferences, conversion or other rights, voting powers,
restrictions, limitations as to distributions, qualifications and terms or
conditions of redemption, as permitted by Maryland law. Because the Board of
Directors has the power to establish the preferences, powers and rights of
each series of Preferred Stock, it may afford the holders of any series of
Preferred Stock preferences, powers and rights, voting or otherwise, senior to
the rights of holders of shares of Common Stock. The issuance of Preferred
Stock could have the effect of delaying or preventing a change of control of
the Company that might involve a premium price for holders of Common Stock or
otherwise be in their best interest. The Board of Directors has no present
plans to issue any Preferred Stock.

RESTRICTIONS ON OWNERSHIP AND TRANSFER

Ownership Limits. In order for the Company to qualify as a REIT under the
Code, no more than 50% in value of its outstanding shares of stock may be
owned, actually or constructively, by five or fewer individuals (as defined in
the Code to include certain entities) during the last half of a taxable year
(other than the first year for which an election to be treated as a REIT has
been made). In addition, if the Company, or an owner of 10% or more of the
Company, actually or constructively owns 10% or more of a tenant of the
Company (or a tenant of any partnership in which the Company is a partner),
the rent received by the Company (either directly or through any such
partnership) from such tenant will not be qualifying income for purposes of
the REIT gross income tests of the Code. A REIT's stock must also be
beneficially owned by 100 or more persons during at least 335 days of a
taxable year of twelve months or during a proportionate part of a shorter
taxable year (other than the first year for which an election to be treated as
a REIT has been made).

Because the Company will elect to qualify as a REIT, the Articles of
Incorporation contain restrictions on the ownership and transfer of Common
Stock which are intended to assist the Company in complying with these
requirements. The Ownership Limit set forth in the Articles of Incorporation
provides that, subject to certain specified exceptions, no person or entity
may own, or be deemed to own by virtue of the applicable constructive
ownership provisions of the Code, more than 7.0% (by number or value,
whichever is more restrictive) of the outstanding shares of Common Stock. The
constructive ownership rules are complex, and may cause shares of Common Stock
owned actually or constructively by a group of related individuals and/or
entities to be constructively owned by one individual or entity. As a result,
the acquisition of less than 7.0% of the shares of Common Stock (or the
acquisition of an interest in an entity that owns, actually or constructively,
Common Stock) by an individual or entity, could, nevertheless cause that
individual or entity, or another individual or entity, to own constructively
in excess of 7.0% of the outstanding Common Stock and thus violate the
Ownership Limit, or such other limit as provided in the Articles of
Incorporation or as otherwise permitted by the Board of

139
<PAGE>

Directors. The Board of Directors may, but in no event will be required to,
waive the Ownership Limit with respect to a particular stockholder if it
determines that such ownership will not jeopardize the Company's status as a
REIT and the Board of Directors otherwise decides such action would be in the
best interest of the Company. As a condition of such waiver, the Board of
Directors may require an opinion of counsel satisfactory to it and/or
undertakings or representations from the applicant with respect to preserving
the REIT status of the Company. The Board of Directors has obtained such
undertakings and representations from John B. Kilroy, Sr. and John B. Kilroy,
Jr. and has waived the Ownership Limit with respect to the actual and
constructive ownership (and to any constructive ownership of securities
therefrom) of Common Stock by John B. Kilroy, Sr. and John B. Kilroy, Jr.
Consequently, John B. Kilroy, Sr., John B. Kilroy, Jr., members of their
families and entities (including the Operating Partnership) which are deemed
to own Messrs. Kilroys' Common Stock under the constructive ownership rules of
the Code will be permitted to own, in the aggregate, actually or
constructively, up to 19.6% (by number of shares or value, whichever is more
restrictive) of the outstanding Common Stock.

The Articles of Incorporation further prohibits (i) any person from actually
or constructively owning shares of stock of the Company that would result in
the Company being "closely held" under Section 856(h) of the Code or otherwise
cause the Company to fail to qualify as a REIT, and (ii) any person from
transferring shares of stock of the Company if such transfer would result in
shares of stock of the Company being beneficially owned by fewer than 100
persons (determined without reference to any rules of attribution).

Any person who acquires or attempts or intends to acquire actual or
constructive ownership of shares of stock of the Company that will or may
violate any of the foregoing restrictions on transferability and ownership is
required to give notice immediately to the Company and provide the Company
with such other information as the Company may request in order to determine
the effect of such transfer on the Company's status as a REIT. The foregoing
restrictions on transferability and ownership will not apply if the Board of
Directors determines that it is no longer in the best interest of the Company
to attempt to qualify, or to continue to qualify, as a REIT. Except as
otherwise described above, any change in the Ownership Limit would require an
amendment to the Articles of Incorporation. Amendments to the Articles of
Incorporation require the affirmative vote of holders owning at least two-
thirds of the shares of the Company's capital stock outstanding and entitled
to vote thereon.

Pursuant to the Articles of Incorporation, if any purported transfer of
Common Stock or any other event would otherwise result in any person violating
the Ownership Limit or such other limit as provided in the Articles of
Incorporation or as otherwise permitted by the Board of Directors, then any
such purported transfer will be void and of no force or effect with respect to
the purported transferee (the "Prohibited Transferee") as to that number of
shares in excess of the Ownership Limit or such other limit, and the
Prohibited Transferee shall acquire no right or interest (or, in the case of
any event other than a purported transfer, the person or entity holding record
title to any such excess shares (the "Prohibited Owner") shall cease to own
any right or interest) in such excess shares. Any such excess shares described
above will be transferred automatically, by operation of law, to a trust, the
beneficiary of which will be a qualified charitable organization selected by
the Company (the "Beneficiary"). Such automatic transfer shall be deemed to be
effective as of the close of business on the business day prior to the date of
such violative transfer. Within 20 days of receiving notice from the Company
of the transfer of shares to the trust, the trustee of the trust (who shall be
designated by the Company and be unaffiliated with the Company and any
Prohibited Transferee or Prohibited Owner) will be required to sell such
excess shares to a person or entity who could own such shares without
violating the Ownership Limit, or such other limit as provided in the Articles
of Incorporation or as otherwise permitted by the Board of Directors, and
distribute to the Prohibited Owner or Prohibited Transferee, as applicable, an
amount equal to the lesser of the price paid by the Prohibited Transferee or
Prohibited Owner for such excess shares or the sales proceeds received by the
trust for such excess shares. In the case of any excess shares resulting from
any event other than a transfer, or from a transfer for no consideration (such
as a gift), the trustee will be required to sell such excess shares to a
qualified person or entity and distribute to the Prohibited Owner or
Prohibited Transferee, as applicable, an amount equal to the lesser of the
Market Price (as defined in the Articles of Incorporation) of such excess
shares as of the date of such event or the sales proceeds received by the
trust for such excess shares. In either case, any proceeds in excess of the
amount distributable to the Prohibited Transferee or Prohibited Owner, as
applicable,

140
<PAGE>

will be distributed to the Beneficiary. Prior to a sale of any such excess
shares by the trust, the trustee will be entitled to receive, in trust for the
Beneficiary, all dividends and other distributions paid by the Company with
respect to such excess shares, and also will be entitled to exercise all
voting rights with respect to such excess shares. Subject to Maryland law,
effective as of the date that such shares have been transferred to the trust,
the trustee shall have the authority (at the trustee's sole discretion) (i) to
rescind as void any vote cast by a Prohibited Transferee or Prohibited Owner,
as applicable, prior to the discovery by the Company that such shares have
been transferred to the trust and (ii) to recast such vote in accordance with
the desires of the trustee acting for the benefit of the Beneficiary. However,
if the Company has already taken irreversible corporate action, then the
trustee shall not have the authority to rescind and recast such vote. Any
dividend or other distribution paid to the Prohibited Transferee or Prohibited
Owner (prior to the discovery by the Company that such shares had been
automatically transferred to a trust as described above) will be required to
be repaid to the trustee upon demand for distribution to the Beneficiary. In
the event that the transfer to the trust as described above is not
automatically effective (for any reason) to prevent violation of the Ownership
Limit or such other limit as provided in the Articles of Incorporation or as
otherwise permitted by the Board of Directors, then the Articles of
Incorporation provide that the transfer of the excess shares will be void.

In addition, shares of stock of the Company held in the trust shall be
deemed to have been offered for sale to the Company, or its designee, at a
price per share equal to the lesser of (i) the price per share in the
transaction that resulted in such transfer to the trust (or, in the case of a
devise or gift, the Market Price at the time of such devise or gift) and (ii)
the Market Price on the date the Company, or its designee, accepts such offer.
The Company shall have the right to accept such offer until the trustee has
sold the shares of stock held in the trust. Upon such a sale to the Company,
the interest of the Beneficiary in the shares sold shall terminate and the
trustee shall distribute the net proceeds of the sale to the Prohibited
Transferee or Prohibited Owner.

If any purported transfer of shares of Common Stock would cause the Company
to be beneficially owned by fewer than 100 persons, such transfer will be null
and void in its entirety and the intended transferee will acquire no rights to
the stock.

All certificates representing shares of Common Stock will bear a legend
referring to the restrictions described above. The foregoing ownership
limitations could delay, defer or prevent a transaction or a change in control
of the Company that might involve a premium price for the Common Stock or
otherwise be in the best interest of stockholders.

Under the Articles of Incorporation, every owner of a specified percentage
(or more) of the outstanding shares of Common Stock must file a completed
questionnaire with the Company containing information regarding their
ownership of such shares, as set forth in the Treasury Regulations. Under
current Treasury Regulations, the percentage will be set between 0.5% and
5.0%, depending upon the number of record holders of the Company's shares of
Common Stock. In addition, each stockholder shall upon demand be required to
disclose to the Company in writing such information as the Company may request
in order to determine the effect, if any, of such stockholder's actual and
constructive ownership of Common Stock on the Company's status as a REIT and
to ensure compliance with the Ownership Limit, or such other limit as provided
in the Articles of Incorporation or as otherwise permitted by the Board of
Directors.

CERTAIN PROVISIONS OF MARYLAND LAW AND OF
THE ARTICLES OF INCORPORATION AND BYLAWS

The following paragraphs summarize certain provisions of the MGCL and the
Articles of Incorporation and Bylaws. The summary does not purport to be
complete and is subject to and qualified in its entirety by reference to the
MGCL and the Articles of Incorporation and Bylaws, copies of which are
exhibits to the Registration Statement of which this Prospectus is a part.

THE BOARD OF DIRECTORS

The Articles of Incorporation provide that the number of directors of the
Company shall be established pursuant to the Bylaws but shall not be less than
the minimum number required by the MGCL, which in the case of the Company is
three. The Bylaws currently provide that the number of directors shall be
fixed or changed by the then elected directors but will consist of not fewer
than five nor more than 13 members. The number of directors is currently fixed
at 5. Any vacancy (except for a vacancy caused by removal) will be filled, at
any regular meeting or at any special meeting called for that purpose, by a
majority of the remaining directors or, in the case of a vacancy resulting
from an increase in the number of directors, by a majority of the entire Board
of Directors. A vacancy resulting from removal will be filled by the
stockholders at the next annual meeting of stockholders or at a special
meeting of the stockholders called for that purpose. The Articles of
Incorporation and Bylaws provide that a majority of the Board must be
"Independent Directors." An "Independent Director" is a director who is not an
employee, officer or affiliate of the Company or a subsidiary or division
thereof, or a relative of a principal executive officer, or who is not an
individual member of an organization acting as advisor, consultant or legal
counsel, receiving compensation on a continuing basis from the Company in
addition to director's fees.

Pursuant to the Articles of Incorporation, the directors are divided into
three classes as nearly equal in size as practicable. One class holds office
initially for a term expiring at the annual meeting of stockholders to be held
in 1998, another class holds office initially for a term expiring at the
annual meeting of stockholders to be held in 1999 and another class holds
office initially for a term expiring at the annual meeting of stockholders to
be held in 2000. As the term of each class expires, directors in that class
will be elected for a term of three years and until their successors are duly
elected and qualified and the directors in the other two classes will continue
in office. The Company believes that classification of the Board of Directors
helps to assure the continuity and stability of the Company's business
strategies and policies as determined by the Board of Directors.

The classified director provision could have the effect of making the
removal of incumbent directors more time consuming and difficult, which could
discourage a third party from making a tender offer or otherwise attempting to
obtain control of the Company, even though such an attempt might be beneficial
to the Company and its stockholders. At least two annual meetings of
stockholders, instead of one, will generally be required to effect a change in
a majority of the Board of Directors. Thus, the classified board provision
could increase the likelihood that incumbent directors will retain their
positions. Holders of shares of Common Stock will have no right to cumulative
voting for the election of directors. Consequently, at each annual meeting of
stockholders, the holders of a majority of the shares of Common Stock will be
able to elect all of the successors of the class of directors whose term
expires at that meeting.

REMOVAL OF DIRECTORS

While the Articles of Incorporation and the MGCL empower the stockholders to
fill vacancies in the Board of Directors that are caused by the removal of a
director, the Articles of Incorporation preclude stockholders from removing
incumbent directors except upon a substantial affirmative vote. Specifically,
the Articles of Incorporation provide that a director may be removed only for
cause and only by the affirmative vote of at least two-thirds of the votes
entitled to be cast in the election of directors. Under the MGCL, the term
"cause" is not defined and is, therefore, subject to Maryland common law and
to judicial interpretation and review in the context of the unique facts and
circumstances of any particular situation. This provision, when coupled with
the provision

142
<PAGE>

in the Bylaws authorizing the Board of Directors to fill vacant directorships,
precludes stockholders from removing incumbent directors except upon a
substantial affirmative vote and filling the vacancies created by such removal
with their own nominees.

BUSINESS COMBINATIONS

Under the MGCL, certain "business combinations" (including a merger,
consolidation, share exchange, or, in certain circumstances, an asset transfer
or issuance or reclassification of equity securities) between the Company and
any person who beneficially owns, directly or indirectly, 10% or more of the
voting power of the Company's shares, or an affiliate of the Company who, at
any time within the two-year period prior to the date in question, was the
beneficial owner of 10% or more of the voting power of the Company's then
outstanding shares (an "Interested Stockholder") or an affiliate thereof are
prohibited for five years after the most recent date on which the Interested
Stockholder became an Interested Stockholder. Thereafter, any such business
combination must be recommended by the Board of Directors and approved by the
affirmative vote of at least (i) 80% of the votes entitled to be cast by
holders of outstanding shares of the Company's voting stock and (ii) two-
thirds of the votes entitled to be cast by holders of outstanding shares of
the Company's voting stock other than shares held by the Interested
Stockholder with whom the business combination is to be effected, unless,
among other things, the Company's stockholders receive a minimum price (as
defined in the MGCL) for their shares of stock and the consideration is
received in cash or in the same form as previously paid by the Interested
Stockholder for its shares. These provisions of the MGCL do not apply,
however, to business combinations that are approved or exempted by the Board
of Directors prior to the time that the Interested Stockholder becomes an
Interested Stockholder. The Board of Directors has resolved to opt out of the
business combinations provisions of the MGCL, and such resolutions also
require that any decision to opt back in be subject to the approval of holders
of a majority of the shares of Common Stock. As a result of the Company's
decision to opt out of the business combinations provisions of the MGCL, an
Interested Stockholder would be able to effect a "business combination"
without complying with the requirements set forth above. The decision to opt
out of the provisions may have the effect of making it easier for stockholders
who become Interested Stockholders to consummate a business combination
involving the Company. However, no assurance can be given that any such
business combination would be consummated or, if consummated, would result in
a purchase of shares of Common Stock from any stockholder at a premium.

CONTROL SHARE ACQUISITIONS

The MGCL provides that "control shares" of the Company acquired in a
"control share acquisition" have no voting rights except to the extent
approved by a vote of two-thirds of the votes entitled to be cast on the
matter, excluding shares owned by the acquiror or by officers or directors who
are employees of the Company. "Control shares" are voting shares of stock
which, if aggregated with all other such shares of stock previously acquired
by the acquiror, or in respect of which the acquiror is able to exercise or
direct the exercise of voting power (except solely by revocable proxy), would
entitle the acquiror to exercise voting power in electing directors within one
of the following ranges of voting power: (i) one-fifth or more but less than
one-third; (ii) one-third or more but less than a majority; or (iii) a
majority of all voting power. "Control shares" do not include shares of stock
the acquiring person is then entitled to vote as a result of having previously
obtained stockholder approval. A "control share acquisition" means the
acquisition of control shares, subject to certain exceptions.

A person who has made or proposes to make a control share acquisition, upon
satisfaction of certain conditions (including an undertaking to pay expenses),
may compel the Board of Directors to call a special meeting of stockholders to
be held within 50 days of demand to consider voting rights for the shares. If
no request for a meeting is made, the Company may itself present the question
at any stockholders' meeting.

If voting rights are not approved at the stockholders' meeting or if the
acquiring person does not deliver an acquiring person statement as required by
the MGCL, then, subject to certain conditions and limitations, the Company may
redeem any or all of the control shares (except those for which voting rights
have previously

143
<PAGE>

been approved) for fair value determined, without regard to the absence of
voting rights for the control shares, as of the date of the last control share
acquisition by the acquiror or of any meeting of stockholders at which the
voting rights of such shares are considered and not approved. If voting rights
for control shares are approved at a stockholders' meeting and the acquiror
becomes entitled to vote a majority of the shares of stock entitled to vote,
all other stockholders may exercise appraisal rights. The fair value of the
shares of stock as determined for purposes of such appraisal rights may not be
less than the highest price per share paid by the acquiror in the control
share acquisition, and certain limitations and restrictions otherwise
applicable to the exercise of dissenters' rights do not apply in the context
of a control share acquisition.

The control share acquisition statute does not apply to shares acquired in a
merger, consolidation or share exchange if the Company is a party to the
transaction, or to acquisitions approved or exempted by the Articles of
Incorporation or Bylaws. The Bylaws contain a provision exempting from the
control share acquisition statute any and all acquisitions by any person of
the Company's shares of stock and also provide that such provision may not be
altered, amended or repealed except by the affirmative vote of a majority of
all votes entitled to be cast by the holders of the issued and outstanding
shares of Common Stock. As a result of the Company's decision to opt out of
the "control share acquisition" provisions of the MGCL, stockholders who
acquire a substantial block of Common Stock are not precluded from exercising
full voting rights with respect to their shares on all matters without first
obtaining the approval of other stockholders entitled to vote. This may have
the effect of making it easier for any such control share stockholder to
effect a business combination with the Company. However, no assurance can be
given that any such business combination would be consummated or, if
consummated, would result in a purchase of shares of Common Stock from any
stockholder at a premium.

AMENDMENT TO THE ARTICLES OF INCORPORATION AND BYLAWS

The Articles of Incorporation may not be amended without the affirmative
vote of at least two-thirds of the shares of capital stock outstanding and
entitled to vote thereon voting together as a single class. Other than
provisions of the Bylaws (i) opting out of the control share acquisition
statute, (ii) requiring approval by the Independent Directors for selection of
operators of the Properties or of transactions involving John B. Kilroy, Sr.
and John B. Kilroy, Jr. and their affiliates and (iii) those governing
amendment of the Bylaws, each of which may be amended only with the approval
of a majority of the shares of capital stock entitled to vote, the Bylaws may
be amended by the affirmative vote of a majority of the Board of Directors or
of a majority of the issued and outstanding shares of the Common Stock.

MEETINGS OF STOCKHOLDERS

The Bylaws provide for annual meetings of stockholders, commencing with the
year 1998, to elect the Board of Directors and transact such other business as
may properly be brought before the meeting. Special meetings of stockholders
may be called by the President, the Board of Directors or the Chairman of the
Board and shall be called at the request in writing of the holders of 50% or
more of the outstanding stock of the Company entitled to vote.

The MGCL provides that any action required or permitted to be taken at a
meeting of stockholders may be taken without a meeting by unanimous written
consent, if such consent sets forth such action and is signed by each
stockholder entitled to vote on the matter and a written waiver of any right
to dissent is signed by each stockholder entitled to notice of the meeting but
not entitled to vote at it.

ADVANCE NOTICE OF DIRECTOR NOMINATIONS AND NEW BUSINESS

The Bylaws provide that (i) with respect to an annual meeting of
stockholders, nominations of persons for election to the Board of Directors
and the proposal of business to be considered by stockholders may be made only
(a) pursuant to the Company's notice of the meeting, (b) by or at the
direction of the Board of Directors or (c) by a stockholder who is entitled to
vote at the meeting and has complied with the advance notice procedures set
forth in the Bylaws, and (ii) with respect to special meetings of
stockholders, only the business specified in the Company's notice of meeting
may be brought before the meeting of stockholders.

144
<PAGE>

The provisions in the Articles of Incorporation on classification of the
Board of Directors and amendments to the Articles of Incorporation and the
advance notice provisions of the Bylaws could have the effect of discouraging
a takeover or other transaction in which holders of some, or a majority, of
the shares of Common Stock might receive a premium for their shares of Common
Stock over the then prevailing market price or which such holders might
believe to be otherwise in their best interests.

DISSOLUTION OF THE COMPANY

Under the MGCL, the Company may be dissolved by (i) the affirmative vote of
a majority of the entire Board of Directors declaring such dissolution to be
advisable and directing that the proposed dissolution be submitted for
consideration at any annual or special meeting of stockholders, and (ii) upon
proper notice, stockholder approval by the affirmative vote of the holders of
two-thirds of the total number of shares of capital stock outstanding and
entitled to vote thereon voting as a single class.

LIMITATION OF DIRECTORS' AND OFFICERS' LIABILITY

The Company's officers and directors are and will be indemnified under
Maryland law, the Articles of Incorporation and the Partnership Agreement
against certain liabilities. The Articles of Incorporation and Bylaws require
the Company to indemnify its directors and officers to the fullest extent
permitted from time to time by the laws of Maryland.

The MGCL permits a corporation to indemnify its directors and officers and
certain other parties against judgments, penalties, fines, settlements, and
reasonable expenses actually incurred by them in connection with any
proceeding to which they may be made a party by reason of their service in
those or other capacities unless it is established that (i) the act or
omission of the director or officer was material to the matter giving rise to
the proceeding and was committed in bad faith or was the result of active and
deliberate dishonesty, (ii) the director or officer actually received an
improper personal benefit in money, property or services, or (iii) in the case
of any criminal proceeding, the director or officer had reasonable cause to
believe that the act or omission was unlawful. Indemnification may be made
against judgments, penalties, fines, settlements and reasonable expenses
actually incurred by the director or officer in connection with the
proceeding; provided, however, that if the proceeding is one by or in the
right of the corporation, indemnification may not be made with respect to any
proceeding in which the director or officer has been adjudged to be liable to
the corporation. In addition, a director or officer may not be indemnified
with respect to any proceeding charging improper personal benefit to the
director or officer in which the director or officer was adjudged to be liable
on the basis that personal benefit was received. The termination of any
proceeding by conviction, or upon a plea of nolo contendere or its equivalent,
or an entry of any order of probation prior to judgment, creates a rebuttable
presumption that the director or officer did not meet the requisite standard
of conduct required for indemnification to be permitted.

The MGCL permits the articles of incorporation of a Maryland corporation to
include a provision limiting the liability of its directors and officers to
the corporation and its stockholders for money damages, subject to specified
restrictions, and the Articles of Incorporation contain this provision. The
law does not, however, permit the liability of directors and officers to the
corporation or its stockholders to be limited to the extent that (i) it is
proved that the person actually received an improper personal benefit in
money, property or services, (ii) a judgment or other final adjudication is
entered in a proceeding based on a finding that the person's action, or
failure to act, was committed in bad faith or was the result of active and
deliberate dishonesty and was material to the cause of action adjudicated in
the proceeding or (iii) in the case of any criminal proceeding, the director
had reasonable cause to believe that the act or failure to act was unlawful.
This provision does not limit the ability of the Company or its stockholders
to obtain other relief, such as an injunction or rescission.

The Partnership Agreement also provides for indemnification of the Company,
as general partner, and its officers and directors to the same extent
indemnification is provided to officers and directors of the Company in its
Articles of Incorporation, and limits the liability of the Company and its
officers and directors to the Operating Partnership and the partners of the
Operating Partnership to the same extent liability of officers and directors
of

145
<PAGE>

the Company to the Company and its stockholders is limited under the Articles
of Incorporation. See "Partnership Agreement of the Operating Partnership--
Indemnification."

Insofar as indemnification for liability arising under the Securities Act
may be permitted to directors, officers or persons controlling the Company
pursuant to the foregoing provisions, the Company has been informed that in
the opinion of the Commission such indemnification is against public policy as
expressed in the Securities Act and is therefore unenforceable.

INDEMNIFICATION AGREEMENTS

The Company has entered into indemnification agreements with each of its
executive officers and directors. The indemnification agreements require,
among other matters, that the Company indemnify its executive officers and
directors to the fullest extent permitted by law and advance to the executive
officers and directors all related expenses, subject to reimbursement if it is
subsequently determined that indemnification is not permitted. Under the
agreements, the Company must also indemnify and advance all expenses incurred
by executive officers and directors seeking to enforce their rights under the
indemnification agreements and may cover executive officers and directors
under the Company's directors' and officers' liability insurance. Although the
form of indemnification agreement offers substantially the same scope of
coverage afforded by law, it provides greater assurance to directors and
executive officers that indemnification will be available, because, as a
contract, it cannot be modified unilaterally in the future by the Board of
Directors or the stockholders to eliminate the rights it provides.

PARTNERSHIP AGREEMENT OF THE OPERATING PARTNERSHIP

The following summary of the Amended and Restated Agreement of Limited
Partnership of the Operating Partnership (the "Partnership Agreement") and the
descriptions of certain provisions set forth elsewhere in this Prospectus, are
qualified in their entirety by reference to the Partnership Agreement, which
is filed as an exhibit to the Registration Statement of which this Prospectus
is a part. See "Additional Information."

MANAGEMENT

The Operating Partnership is organized as a Delaware limited partnership
pursuant to the terms of the Partnership Agreement. Kilroy Realty Corporation
is the sole general partner of the Operating Partnership and presently holds
an 83.7% economic interest in the Operating Partnership (89.7% after giving
effect to the Offering and the application of the net offering proceeds
therefrom as set forth under the caption "Use of Proceeds.") of the economic
interests in, the Operating Partnership. The Company conducts substantially
all of its business through the Operating Partnership, except for development
and certain other services (which are conducted through the Services Company)
in order to preserve the Company's REIT status. The Operating Partnership owns
a 95.0% economic interest in the Services Company. Generally, pursuant to the
Partnership Agreement, the Company, as the sole general partner of the
Operating Partnership, has full, exclusive and complete responsibility and
discretion in the management and control of the Operating Partnership,
including the ability to cause the Operating Partnership to enter into certain
major transactions including acquisitions, dispositions and refinancings and
to cause changes in the Operating Partnership's line of business and
distribution policies. The Unitholders, as limited partners of the Operating
Partnership, have no authority to transact business for, or participate in the
management activities or decisions of, the Operating Partnership, except as
provided in the Partnership Agreement and as required by applicable law.

INDEMNIFICATION

To the extent permitted by law, the Partnership Agreement provides for
indemnification of the Company, as general partner, its officers and directors
and such other persons as the Company may designate to the same extent
indemnification is provided to officers and directors of the Company in its
Articles of Incorporation, and limits the liability of the Company and its
officers and directors to the Operating Partnership to the same extent
liability of officers and directors of the Company is limited under the
Articles of Incorporation.

TRANSFERABILITY OF INTERESTS

Except for a transaction described in the following two paragraphs, the
Partnership Agreement provides that the Company may not voluntarily withdraw
from the Operating Partnership, or transfer or assign its interest in the
Operating Partnership, without the consent of the holders of at least 60% of
the partner interests (including the interests of the Company, which will
represent approximately 89.7% of the total partner interests upon consummation
of the Offering and the application of the net offering proceeds therefrom as
set forth under the caption "Use of Proceeds"). Pursuant to the Partnership
Agreement, the limited partners have agreed not to, prior to January 31, 1999,
transfer, assign, sell, encumber or otherwise dispose of, without the consent
of the Company, their interest in the Operating Partnership, other than to
family members or accredited investors who agree to assume the obligations of
the transferor under the Partnership Agreement subject to a right of first
refusal for the benefit of the Company. The Unitholders are subject to
additional restrictions on their ability to transfer shares of Common Stock.
See "Underwriting."

The Company may not engage in any merger, consolidation or other combination
with or into another person, sale of all or substantially all of its assets or
any reclassification, recapitalization or change of its outstanding equity
interests (each a "Termination Transaction") unless the Termination
Transaction has been approved by holders of at least 60% of the Units
(including Units held by the Company, which will represent approximately 89.7%
of all Units outstanding upon consummation of the Offering and the application
of the net offering proceeds therefrom as set forth under the caption "Use of
Proceeds") and in connection with which

147
<PAGE>

all limited partners either will receive, or will have the right to elect to
receive, for each Unit an amount of cash, securities or other property equal
to the product of the number of shares of Common Stock into which each Unit is
then exchangeable and the greatest amount of cash, securities or other
property paid to the holder of one share of Common Stock in consideration of
one share of Common Stock pursuant to the Termination Transaction. If, in
connection with the Termination Transaction, a purchase, tender or exchange
offer shall have been made to and accepted by the holders of the outstanding
shares of Common Stock, each holder of Units will receive, or will have the
right to elect to receive, the greatest amount of cash, securities or other
property which such holder would have received had it exercised its right to
redemption and received shares of Common Stock in exchange for its Units
immediately prior to the expiration of such purchase, tender or exchange offer
and had thereupon accepted such purchase, tender or exchange offer.

The Company may also merge or otherwise combine its assets with another
entity if the following conditions are met: (i) substantially all of the
assets directly or indirectly owned by the surviving entity are held directly
or indirectly by the Operating Partnership or another limited partnership or
limited liability company which is the survivor of a merger, consolidation or
combination of assets with the Operating Partnership (in each case, the
"Surviving Partnership"); (ii) the limited partners own a percentage interest
of the Surviving Partnership based on the relative fair market value of the
net assets of the Operating Partnership and the other net assets of the
Surviving Partnership immediately prior to the consummation of such
transaction; (iii) the rights, preferences and privileges of the limited
partners in the Surviving Partnership are at least as favorable as those in
effect immediately prior to the consummation of such transaction and as those
applicable to any other limited partners or non-managing members of the
Surviving Partnership; and (iv) such rights of the limited partners include
the right to exchange their interests in the Surviving Partnership for at
least one of the following: (a) the consideration available to such persons
pursuant to the preceding paragraph, or (b) if the ultimate controlling person
of the Surviving Partnership has publicly traded common equity securities,
such common equity securities, with an exchange ratio based on the relative
fair market value of such securities and the Common Stock. For purposes of
this paragraph, the determination of relative fair market values and rights,
preferences and privileges of the limited partners shall be reasonably
determined by the Board of Directors as of the time of the Termination
Transaction and, to the extent applicable, the values shall be no less
favorable to the limited partners than the relative values reflected in the
terms of the Termination Transaction.

In respect of any transaction described in the preceding two paragraphs, the
Company is required to use its commercially reasonable efforts to structure
such transaction to avoid causing the limited partners to recognize gain for
federal income tax purposes by virtue of the occurrence of or their
participation in such transaction. The Operating Partnership will also use
commercially reasonable efforts to cooperate with the limited partners to
minimize any taxes payable in connection with any repayment, refinancing,
replacement or restructuring of indebtedness, or any sale, exchange or any
other disposition of assets, of the Operating Partnership.

ISSUANCE OF ADDITIONAL UNITS

As sole general partner of the Operating Partnership, the Company has the
ability to cause the Operating Partnership to issue additional Units
representing general and limited partnership interests in the Operating
Partnership, including preferred Units of limited partnership interests.

CAPITAL CONTRIBUTION

The Partnership Agreement provides that if the Operating Partnership
requires additional funds at any time or from time to time in excess of funds
available to the Operating Partnership from borrowings or capital
contributions, the Company may borrow such funds from a financial institution
or other lender or through public or private debt offerings and lend such
funds to the Operating Partnership on the same terms and conditions as are
applicable to the Company's borrowing of such funds. As an alternative to
borrowing funds required by the Operating Partnership, the Company may
contribute the amount of such required funds as an additional capital
contribution to the Operating Partnership. If the Company so contributes
additional capital to the Operating Partnership, the Company's partnership
interest in the Operating Partnership will be increased on a proportionate

148
<PAGE>

basis. Conversely, the partnership interests of the limited partners will be
decreased on a proportionate basis in the event of additional capital
contributions by the Company. See "Policies With Respect to Certain
Activities--Financing."

AWARDS UNDER STOCK INCENTIVE PLAN

If options granted in connection with the Stock Incentive Plan are exercised
at any time or from time to time, or restricted shares of Common Stock are
issued under the Stock Incentive Plan, the Partnership Agreement requires the
Company to contribute to the Operating Partnership as an additional
contribution the exercise price received by the Company in connection with the
issuance of shares of Common Stock to such exercising participant or the
proceeds received by the Company upon issuance of the shares. Upon such
contribution the Company will be issued a number of Units in the Operating
Partnership equal to the number of shares of Common Stock so issued.

REDEMPTION/EXCHANGE RIGHTS

Limited partners have rights to require the Operating Partnership to redeem
part or all of their Units for cash (based upon the fair market value of an
equivalent number of shares of Common Stock at the time of such redemption) or
the Company may elect to exchange such Units for shares of Common Stock (on a
one-for-one basis, subject to adjustment in the event of stock splits, stock
dividends, issuance of certain rights, certain extraordinary distributions and
similar events); provided, however, that if the Company does not elect to
exchange such Units for shares of Common Stock, a holder of Units that is a
corporation or a limited liability company may require the Company to issue
Common Stock in lieu thereof, subject to the Ownership Limit or such other
limit as provided in the Articles of Incorporation or as otherwise permitted
by the Board of Directors, as applicable. The Company presently anticipates
that it will elect to issue Common Stock in exchange for Units in connection
with each such redemption request, rather than having the Operating
Partnership pay cash. With each such redemption or exchange, the Company's
percentage ownership interest in the Operating Partnership will increase. This
redemption/exchange right may be exercised by limited partners from time to
time, in whole or in part, subject to the limitations that such right may not
be exercised (i) prior to January 31, 1999 or (ii) at any time to the extent
such exercise would result in any person actually or constructively owning
Common Stock in excess of the Ownership Limit or such other amount as provided
in the Articles of Incorporation or as otherwise permitted by the Board of
Directors, as applicable, assuming Common Stock was issued in such exchange.
See "Description of Capital Stock--Restrictions on Ownership and Transfer." In
addition, under certain circumstances 50% of the Units received by John B.
Kilroy, Sr., John B. Kilroy, Jr. and KI may be redeemed prior to January 31,
1999 in connection with the obligation of such Unitholders to indemnify the
Company in connection with the Formation Transactions. See "Formation and
Structure of the Company--Formation Transactions."

REGISTRATION RIGHTS

For a description of certain registration rights held by the Unitholders,
see "Shares Eligible for Future Sale--Redemption/Exchange Rights and
Registration Rights."

TAX MATTERS

Pursuant to the Partnership Agreement, the Company is the tax matters
partner of the Operating Partnership and, as such, has authority to make tax
elections under the Code on behalf of the Operating Partnership.

The net income or net loss of the Operating Partnership will generally be
allocated to the Company and the limited partners in accordance with their
respective percentage interests in the Operating Partnership, subject to
compliance with the provisions of Sections 704(b) and 704(c) of the Code and
the Treasury Regulations promulgated thereunder. See "Federal Income Tax
Consequences--Tax Aspects of the Partnerships."

149
<PAGE>

OPERATIONS

The Partnership Agreement requires that the Operating Partnership be
operated in a manner that will enable the Company to satisfy the requirements
for being classified as a REIT and to avoid any federal income tax liability.
The Partnership Agreement provides that the net operating cash revenues of the
Operating Partnership, as well as net sales and refinancing proceeds, will be
distributed from time to time as determined by the Company (but not less
frequently than quarterly) pro rata in accordance with the partners'
respective percentage interests. Pursuant to the Partnership Agreement, the
Operating Partnership assumes and pays when due, or reimburses the Company for
payment of, all expenses it incurs relating to the ownership and operation of,
or for the benefit of, the Operating Partnership and all costs and expenses
relating to the operations of the Company.

DUTIES AND CONFLICTS

Except as otherwise set forth in "Policies with Respect to Certain
Activities--Conflicts of Interest Policies" and "Management--Employment
Agreements," any limited partner of the Operating Partnership may engage in
other business activities outside the Operating Partnership, including
business activities that directly compete with the Operating Partnership.

CERTAIN LIMITED PARTNER APPROVAL RIGHTS

The Partnership Agreement provides that if the limited partners own at least
5% of the outstanding Units (including Units held by the Company), the Company
shall not, on behalf of the Operating Partnership, take any of the following
actions without the prior consent of the holders of more than 50% (excluding
Units held by the Company) of the Units representing limited partner
interests: (i) dissolve the Operating Partnership, other than incident to a
merger or sale of substantially all of the Company's assets; or (ii) prior to
January 31, 2004, sell the Office Property located at 2260 E. Imperial
Highway, at Kilroy LAX, other than incident to a merger or sale of
substantially all of the Company's assets. In addition, in connection with the
acquisition of the Warren Technology Center and the office building located at
111 Pacifica, Irvine, California, the Company agreed not to dispose of such
Properties in a taxable transaction before January 31, 1999, or thereafter
unless a shelf registration statement is then in effect with respect to the
shares of Common Stock issuable upon the exchange of the 165,102 limited
partnership Units issued to limited partners in connection with the
acquisition of such Properties.

TERM

The Operating Partnership will continue in full force and effect until
December 31, 2095 or until sooner dissolved pursuant to the terms of the
Partnership Agreement.

DESCRIPTION OF INDEBTEDNESS

The following paragraphs summarize certain provisions of the Credit
Facility, the $84.0 Million Loan and the SeaTac Loan. The summary does not
purport to be complete and is subject to and qualified in its entirety by
reference to the Revolving Credit Agreement, dated as of May 21, 1997 between
Kilroy Realty, L.P. and the banks listed therein, the Credit Agreement between
Kilroy Finance and the banks named therein, and the Variable Interest Rate

THE CREDIT FACILITY

On May 21, 1997, the Company, on behalf of the Operating Partnership,
obtained from MGT the two-year, $150.0 million revolving Credit Facility.
There is a one-year option to extend the term of the Credit Facility. On July
28, 1997, the Company received a commitment to increase the Credit Facility to
$200.0 million. The Credit Facility is used primarily to finance acquisitions
of additional properties. Payment of principal and interest is secured by
substantially all of the Properties other than Properties securing the
Mortgage Loans. In addition, borrowings under the Credit Facility are recourse
obligations of the Operating Partnership.

Availability under the Credit Facility is subject to the value of the
underlying collateral securing it. As of July 25, 1997, approximately
$95.0 million is outstanding. The Operating Partnership's ability to borrow
under the Credit Facility is subject to its compliance with the following
covenants on an ongoing basis: a ratio of Net Operating Cash Flow (as defined
below) to Debt Service (as defined below) of 1.75-to-1; a loan to collateral
value ratio of not more than 60%; a ratio of debt to tangible fair market
value of real property assets owned by the Operating Partnership of not more
than 50%; a ratio of annual earnings before income taxes, depreciation and
amortization to Debt Service of at least 2-to-1; limitations on distributions
to 95% of funds from operations; consolidated tangible net worth of the
Operating Partnership of not less than 90% of the Operating Partnership's
consolidated tangible net worth as of January 28, 1997; maintenance of the
Company's status as a REIT for federal income tax purposes and compliance with
all applicable regulations in connection with such status; maintenance of
collateral; a limit of $5.0 million of recourse debt; limitations on the
incurrence of additional indebtedness; and other customary covenants. "Debt
Service" means the greater of (a) measured as of the last day of each calendar
quarter, an amount equal to the interest actually payable by the Operating
Partnership on the loans for the previous four consecutive quarters including
the quarter then ended or (b) the amount of debt service payments determined
by applying a 25-year mortgage style amortization schedule to the loans
outstanding as of the last day of each such calendar quarter, using an
interest rate equal to the treasury rate plus 1.75%. "Net Operating Cash Flow"
means, as of any date of determination, with respect to all mortgaged
properties, property income for the previous four consecutive quarters
including the quarter then ended, but less (a) property expenses with respect
to all such mortgaged properties for the previous four consecutive quarters
including the quarter then ended, and (b) the greater of (i) capital
expenditures which are not related to new construction for the previous four
consecutive quarters including the quarter then ended, and (ii) appropriate
reserves for replacements of not less than $0.20 per square foot of space
subject to leases per annum for each mortgaged property which is an office
property, and $0.15 per square foot of space subject to leases per annum for
each mortgaged property which is an industrial property. Based on the interest
rate selected, each advance under the Credit Facility bears interest at a rate
equal to either (a) 0.25% plus a rate (the "Prime Rate") equal to the higher
of (i) MGT's prime rate then in effect or (ii) the federal funds rate plus
0.50%, or (b) 1.5% plus the LIBOR rate applicable to the selected interest
period, which period may be one, two, three or six months. The Company and the
Operating Partnership anticipate that the Credit Facility will be either
extended, renewed or refinanced through the issuance of debt or equity
securities at its maturity.

THE $84.0 MILLION LOAN

In connection with the IPO, the Company obtained the $84.0 million mortgage
loan from MGT (the "84.0 Million Loan"). The proceeds of the loan were used to
repay indebtedness on certain of the Properties

151
<PAGE>

that were owned by the Company upon completion of the IPO. The $84.0 Million
Loan is secured by the Properties owned by the Company upon completion of the
IPO other than the five office buildings comprising Kilroy Long Beach and the
three office buildings comprising the SeaTac Office Center.

The $84.0 Million Loan requires monthly payments of $667,921. This loan
matures on February 1, 2022, and until January 31, 2005 (the "Reset Date"),
bears interest at 8.35%. On the Reset Date the interest rate for the $84.0
Million Loan will increase to a rate equal to the greater of 13.35% and the
sum of the yield of noncallable for U.S. Treasury Securities maturing 15 years
from the Reset Date plus 5.0%. The $84.0 Million Loan is secured by cross-
collateralized and cross-defaulted mortgages on certain of the Properties. The
$84.0 Million Loan may not be prepaid during the first four years of the loan
term commencing on March 1, 1997. Thereafter the loan may be repaid in whole
or in part, subject to a prepayment premium. The $84.0 Million Loan requires
reserves for current taxes and insurance, capital expenditures and tenant
improvements and leasing commissions. An improvements and repairs reserve of
approximately $1.2 million has been established, which reserve will be
released upon completion of the improvements; a replacement reserve is funded
monthly at an annual rate of approximately $.20 per rentable square foot of
the collateral; and a reserve of approximately $908,000 was established to
make certain earthquake-related structural modifications of which $500,000
remains to be spent for such improvements as of July 31, 1997. A tenant
improvement and leasing commission reserve will commence on February 1, 1998;
the Company presently anticipates that the average balance of this reserve
will be approximately $1.0 million in each of the first four years of the
reserve. In addition, the $84.0 Million Loan includes customary
representations and warranties and requires the borrower to comply with the
following affirmative and negative covenants: limitations on the incurrence of
additional indebtedness; limitations on advances to and investments in others
(including the guaranty of any obligations of another person); limitations on
the transfer or sale of assets including the collateral; limitations on merger
and acquisition transactions; maintenance of minimum levels of insurance;
maintenance of collateral; and other customary covenants. The $84.0 Million
Loan was incurred by the Finance Partnership which is wholly-owned by the
Company and the Operating Partnership and which is structured to be a
"bankruptcy remote" financing vehicle. The Properties used as collateral for
the $84.0 Million Loan have been transferred to that limited partnership.
Subject to certain limited exceptions, the $84.0 Million Loan is non-recourse
to the Company.

THE SEATAC LOAN

Also in connection with the IPO, the Company obtained the $12.0 million
SeaTac Loan from MGT. The proceeds of the SeaTac Loan were used to repay
indebtedness on, and the SeaTac Loan is secured by, the three buildings
comprising the SeaTac Office Center. The SeaTac Loan bears interest at a
variable rate equal to the 30-day LIBOR plus 1.5% and matures on January 31,
1998. The SeaTac Loan requires monthly payments of interest. The SeaTac Loan
is secured by the ground leasehold interest in the SeaTac Office Center.
Principal and interest under the SeaTac Loan is full recourse to the Company.
On August 13, 1997, the Company increased the loan by $2.0 million to $14.0
million.

SHARES ELIGIBLE FOR FUTURE SALE

GENERAL

Upon the consummation of the Offering, the Company will have issued and
outstanding 24,475,000 shares of Common Stock in the public market (excluding
the 1,500,000 shares which are subject to the Underwriters' over-allotment
option), of which 24,375,000 (or 25,875,000 if the Underwriters' over-
allotment option is exercised in full) will be freely tradable in the public
market by persons other than "affiliates" of the Company without restriction
or registration under the Securities Act.

In connection with the IPO, each of the Unitholders who were limited
partners at the time of the IPO agreed not to, directly or indirectly, offer,
sell, offer to sell, contract to sell, pledge, grant any option to purchase or
otherwise dispose or transfer (or announce any offer, sale, offer of sale,
contract of sale, pledge, grant of any option to purchase or other disposition
or transfer) of any Units or shares of Common Stock or other capital stock of
the Company, or of securities substantially similar thereto, or any other
securities convertible into, or exercisable or exchangeable for, any Units or
shares of Common Stock or other capital stock, or such similar securities,
until January 28, 1999. In addition, four other Unitholders that are limited
partners who hold an aggregate of 165,102 limited partnership Units agreed in
connection with the issuance of such Units not to exchange such Units for
shares of Common Stock prior to January 29, 1999. The Company, in connection
with this Offering, has agreed not to, directly or indirectly, offer, sell,
offer to sell, contract to sell, pledge, grant any option to purchase or
otherwise dispose or transfer (or announce any offer, sale, offer of sale,
contract of sale, pledge, grant of any option to purchase or other disposition
or transfer) of any (other than pursuant to the Stock Incentive Plan) Units or
shares of Common Stock or other capital stock of the Company, or of securities
substantially similar thereto, or any other securities convertible into, or
exercisable or exchangeable for, any Units or shares of Common Stock or other
capital stock of the Company or such similar securities, for a period of 180
days from the date of this Prospectus, in each case without the prior written
consent of Prudential Securities Incorporated, on behalf of the Underwriters,
subject to certain limited exceptions. Prudential Securities Incorporated may,
at any time and without notice, release all or any portion of the shares of
Common Stock subject to such lock-up agreements. Notwithstanding the
foregoing, 50% of the Units received by John B. Kilroy, Sr., John B. Kilroy,
Jr. and Kilroy Industries in connection with consummation of the IPO have been
pledged to secure their indemnification obligations pursuant to an agreement
with the Company. See "Formation and Structure of the Company."

The shares of Common Stock owned by "affiliates" of the Company, the 100,000
restricted shares of Common Stock issued to an officer of the Company who is
not a Unitholder and the shares of Common Stock issuable upon exchange of
Units (other than those issued pursuant to registration rights, as described
below), are subject to Rule 144 and may not be sold in the absence of
registration under the Securities Act unless an exemption from registration is
available, including exemptions contained in Rule 144.

In general, under Rule 144 as currently in effect, a person (or persons
whose shares are aggregated with them in accordance with Rule 144) who has
beneficially owned "restricted shares" (defined generally as shares acquired
from the issuer or an affiliate in a non-public transaction) for at least one
year, as well as any person who purchased unrestricted shares on the open
market who may be deemed an affiliate of the Company, would be entitled to
sell, subject to certain manner of sale, public information and notice
requirements, within any three-month period, a number of shares of Common
Stock that does not exceed the greater of 1% of the then-outstanding number of
shares of Common Stock or 1% of the average weekly trading volume of those
shares during the four calendar weeks preceding each such sale. After
restricted shares are held for two years, a person who is not then deemed an
affiliate of the Company is entitled to sell such shares under Rule 144(k)
without regard to these volume limitations. Sales of shares of Common Stock by
affiliates of the Company will continue to be subject to the volume
limitations, unless resold under an effective registration statement under the
Securities Act. In addition, the Commission has recently proposed further
revisions to the holding and volume limitations contained in Rule 144. The
adoption of amendments effecting such proposed revisions may result in resales
of restricted securities sooner than would be the case under Rule 144 and Rule
144(k) as currently in effect. However, there can be no assurance of when, if
ever, such amendments will be proposed or adopted.

The Company has established the Stock Incentive Plan for the purpose of
attracting and retaining executive officers, directors and other key
employees. See "Management--Stock Incentive Plan." As of March 31, 1997,

153
<PAGE>

the Company has issued in the aggregate options to purchase 1,185,000 shares
of Common Stock to executive officers, directors and certain key employees and
has reserved 215,000 additional shares of Common Stock for future issuance
under the Stock Incentive Plan.

No prediction can be made as to the effect, if any, that future sales of
shares of Common Stock (including sales pursuant to Rule 144) or the
availability of shares of Common Stock for future sale will have on the market
price prevailing from time to time. Sales of substantial amounts of shares of
Common Stock (including shares of Common Stock issued upon the exercise of
options or the exchange of Units), or the perception that such sales could
occur, could adversely affect prevailing market prices of the shares of Common
Stock and impair the Company's ability to obtain additional capital through
the sale of equity securities. See "Risk Factors--Shares Eligible for Future
Sale." For a description of certain restrictions on transfers of Common Stock
held by certain stockholders of the Company, see "Underwriting" and
"Description of Capital Stock--Restrictions on Ownership and Transfer."

REDEMPTION/EXCHANGE RIGHTS AND REGISTRATION RIGHTS

Each limited partner of the Operating Partnership has the right to require
the Operating Partnership to redeem part or all of their Units for cash (based
on the fair market value of an equivalent number of shares of Common Stock at
the time of such redemption) or, at the election of the Company, to exchange
such Units for shares of Common Stock, at any time after January 28, 1999
subject to the obligation of John B. Kilroy, Sr., John B. Kilroy, Jr. and
Kilroy Industries, with respect to 50% of their limited partnership Units, to
indemnify the Company in connection with the Formation Transactions. See
"Formation and Structure of the Company--Formation Transactions." If the
Company does not elect to exchange such Units for shares of Common Stock, a
Unitholder that is a corporation or a limited liability company may require
the Company to issue shares of Common Stock in lieu of cash, subject to the
Ownership Limit or such other amount as provided in the Articles of
Incorporation, or as permitted by the Board of Directors, as applicable. As of
June 30, 1997, an aggregate of approximately 2,817,476 Units are held by
limited partners of the Operating Partnership. If the Company elects to
exchange Units for Common Stock, each Unit will be exchangeable for one share
of Common Stock, subject to adjustment in the event of stock splits,
distribution of rights, extraordinary dividends and similar events.

In order to protect the Company's status as a REIT, a holder of Units is
prohibited from exchanging such Units for shares of Common Stock, to the
extent that as a result of such exchange any person would own or would be
deemed to own, actually or constructively, more than 7.0% of the Common Stock,
except to the extent such holder has been granted an exception to the
Ownership Limit. See "Description of Capital Stock--Restrictions on Ownership
and Transfer."

The Company has granted the Unitholders certain registration rights
(collectively, the "Registration Rights") with respect to the shares of Common
Stock acquired upon exchange of limited partnership Units or otherwise (the
"Registrable Shares"). The Company has agreed to file and generally keep
continuously effective beginning on January 31, 1999 a registration statement
covering the issuance of shares of Common Stock upon exchange of Units and the
resale thereof. In addition, the Company has granted the Unitholders piggyback
registration rights with respect to shares of Common Stock acquired by them by
any means. The Company also has agreed to provide the Registration Rights to
any other person who may become an owner of Units, provided such person
provides the Company with satisfactory undertakings. The Company will bear
expenses incident to its registration obligations upon the exercise of the
Registration Rights, including the payment of federal securities law and state
Blue Sky registration fees, except that it will not bear any underwriting
discounts or commissions or transfer taxes relating to registration of
Registrable Shares.

REINVESTMENT AND SHARE PURCHASE PLAN

The Company is considering the adoption of a Distribution Reinvestment and
Share Purchase Plan that would allow stockholders to automatically reinvest
cash distributions on their outstanding shares of Common Stock and/or Units to
purchase additional shares of Common Stock at a discounted price and without
the payment of any brokerage commission or service charge. Stockholders would
also have the option of investing limited additional amounts by making cash
payments. No decision has been made yet by the Company whether or not to adopt
such a plan and there can be no assurance that such a plan will ever be
adopted by the Company.

FEDERAL INCOME TAX CONSEQUENCES

The following summary of material federal income tax considerations
regarding the Company and the Offering is based on current law, is for general
information only and is not tax advice. The information set forth below, to
the extent that it constitutes matters of law, summaries of legal matters or
legal conclusions, is the opinion of Latham & Watkins, tax counsel to the
Company, as to the material federal income tax considerations relevant to
purchasers of the Common Stock. This discussion does not purport to deal with
all aspects of taxation that may be relevant to particular stockholders in
light of their personal investment or tax circumstances, or to certain types
of stockholders subject to special treatment under the federal income tax
laws, including, without limitation, certain financial institutions, life
insurance companies, dealers in securities or currencies, stockholders holding
Common Stock as part of a conversion transaction, as part of a hedge or
hedging transaction, or as a position in a straddle for tax purposes, tax-
exempt organizations (except to the extent discussed under the heading "--
Taxation of Tax-Exempt Stockholders") or foreign corporations, foreign
partnerships and persons who are not citizens or residents of the United
States (except to the extent discussed under the heading "Taxation of Non-U.S.
Stockholders"). In addition, the summary below does not consider the effect of
any foreign, state, local or other tax laws that may be applicable to
prospective stockholders.

EACH PROSPECTIVE PURCHASER IS ADVISED TO CONSULT HIS OR HER OWN TAX ADVISOR
REGARDING THE SPECIFIC TAX CONSEQUENCES TO HIM OR HER OF THE PURCHASE,
OWNERSHIP AND SALE OF THE COMMON STOCK, INCLUDING THE FEDERAL, STATE, LOCAL,
FOREIGN AND OTHER TAX CONSEQUENCES OF SUCH PURCHASE, OWNERSHIP AND SALE AND OF
POTENTIAL CHANGES IN APPLICABLE TAX LAWS.

TAXATION OF THE COMPANY

General. The Company intends to make an election to be taxed as a REIT under
Sections 856 through 860 of the Code commencing with its taxable year ending
December 31, 1997. The Company believes that, commencing with its taxable year
ending December 31, 1997, it has been organized and has operated in such a
manner as to qualify for taxation as a REIT under the Code commencing with
such taxable year, and the Company intends to continue to operate in such a
manner, but no assurance can be given that it has operated or will continue to
operate in such a manner so as to qualify or remain qualified.

These sections of the Code and the corresponding Treasury Regulations are
highly technical and complex. The following sets forth the material aspects of
the sections that govern the federal income tax treatment of a REIT and its
stockholders. This summary is qualified in its entirety by the applicable Code
provisions, rules and regulations promulgated thereunder, and administrative
and judicial interpretations thereof.

Latham & Watkins has acted as tax counsel to the Company in connection with
the IPO, the Offering and the Company's election to be taxed as a REIT. In the
opinion of Latham & Watkins, commencing with the Company's taxable year ending
December 31, 1997, the Company has been organized in conformity with the
requirements for qualification as a REIT, and its method of operation has
enabled, and its proposed method of operation will enable, it to meet the
requirements for qualification and taxation as a REIT under the Code. It must
be emphasized that this opinion is based on various factual assumptions
relating to the organization and operation of the Company (including the
Finance Company, the Operating Partnership, the Finance Partnership, and the
Services Company), and is conditioned upon certain representations made by the
Company as to factual matters. In addition, this opinion is based upon the
factual representations of the Company concerning its business and properties
as set forth in this Prospectus. Moreover, such qualification and taxation as
a REIT depends upon the Company's ability to meet (through actual annual
operating results, distribution levels and diversity of stock ownership) the
various qualification tests imposed under the Code discussed below, the
results of which have not been and will not be reviewed by Latham & Watkins.
Accordingly, no assurance can be given that the actual results of the
Company's operation for any particular taxable year will satisfy such
requirements. Further, the anticipated income tax treatment described in this
Prospectus may be changed, perhaps retroactively, by legislative,
administrative or judicial action at any time. See "--Failure to Qualify."

155
<PAGE>

If the Company qualifies for taxation as a REIT, it generally will not be
subject to federal corporate income taxes on its net income that is currently
distributed to stockholders. This treatment substantially eliminates
the"double taxation" (at the corporate and stockholder levels) that generally
results from investment in a regular corporation. However, the Company will be
subject to federal income tax as follows. First, the Company will be taxed at
regular corporate rates on any undistributed "REIT taxable income," including
undistributed net capital gains. Second, under certain circumstances, the
Company may be subject to the "alternative minimum tax" on its items of tax
preference. Third, if the Company has (i) net income from the sale or other
disposition of "foreclosure property" (defined generally as property acquired
by the Company through foreclosure or otherwise after a default on a loan
secured by the property or a lease of the property) which is held primarily
for sale to customers in the ordinary course of business or (ii) other
nonqualifying income from foreclosure property, it will be subject to tax at
the highest corporate rate on such income. Fourth, if the Company has net
income from prohibited transactions (which are, in general, certain sales or
other dispositions of property held primarily for sale to customers in the
ordinary course of business other than foreclosure property), such income will
be subject to a 100% tax. Fifth, if the Company should fail to satisfy the 75%
gross income test or the 95% gross income test (as discussed below), but has
nonetheless maintained its qualification as a REIT because certain other
requirements have been met, it will be subject to a 100% tax on an amount
equal to (a) the gross income attributable to the greater of the amount by
which the Company fails the 75% or 95% test multiplied by (b) a fraction
intended to reflect the Company's profitability. Sixth, if the Company should
fail to distribute during each calendar year at least the sum of (i) 85% of
its REIT ordinary income for such year, (ii) 95% of its REIT capital gain net
income for such year, and (iii) any undistributed taxable income from prior
periods, the Company would be subject to a 4% excise tax on the excess of such
required distribution over the amounts actually distributed. Seventh, with
respect to any asset (a "Built-In Gain Asset") acquired by the Company from a
corporation which is or has been a C corporation (i.e., generally a
corporation subject to full corporate-level tax) in a transaction in which the
basis of the Built-In Gain Asset in the hands of the Company is determined by
reference to the basis of the asset in the hands of the C corporation, if the
Company recognizes gain on the disposition of such asset during the ten-year
period (the "Recognition Period") beginning on the date on which such asset
was acquired by the Company, then, to the extent of the Built-In Gain (i.e.,
the excess of (a) the fair market value of such asset over (b) the Company's
adjusted basis in such asset, determined as of the beginning of the
Recognition Period), such gain will be subject to tax at the highest regular
corporate rate pursuant to Treasury Regulations that have not yet been
promulgated. The results described above with respect to the recognition of
Built-In Gain assume that the Company will make an election pursuant to IRS
Notice 88-19.

Requirements for Qualification. The Code defines a REIT as a corporation,
trust or association (i) which is managed by one or more trustees or
directors; (ii) the beneficial ownership of which is evidenced by transferable
shares, or by transferable certificates of beneficial interest; (iii) which
would be taxable as a domestic corporation, but for Sections 856 through 859
of the Code; (iv) which is neither a financial institution nor an insurance
company subject to certain provisions of the Code; (v) the beneficial
ownership of which is held by 100 or more persons; (vi) during the last half
of each taxable year not more than 50% in value of the outstanding stock of
which is owned, actually or constructively, by five or fewer individuals (as
defined in the Code to include certain entities); and (vii) which meets
certain other tests, described below, regarding the nature of its income and
assets. The Code provides that conditions (i) to (iv), inclusive, must be met
during the entire taxable year and that condition (v) must be met during at
least 335 days of a taxable year of twelve months, or during a proportionate
part of a taxable year of less than twelve months. Conditions (v) and (vi)
will not apply until after the first taxable year for which an election is
made to be taxed as a REIT. For purposes of conditions (v) and (vi), pension
funds and certain other tax-exempt entities are treated as individuals,
subject to a "look-through" exception in the case of condition (vi).

The Company believes that the conditions set forth in (i) through (iv) above
have been satisfied. The Company also believes that it has issued sufficient
shares of Common Stock with sufficient diversity of ownership pursuant to the
Offering to allow it to satisfy conditions (v) and (vi). In addition, the
Articles of Incorporation provide for restrictions regarding the transfer and
ownership of shares, which restrictions are intended to assist the Company in
continuing to satisfy the share ownership requirements described in (v) and
(vi) above. Such ownership and transfer restrictions are described in
"Description of Capital Stock--Restrictions

156
<PAGE>

on Ownership and Transfer." These restrictions, however, may not ensure that
the Company will, in all cases, be able to satisfy the share ownership
requirements described above. If the Company fails to satisfy such share
ownership requirements, the Company's status as a REIT will terminate. See "--
Failure to Qualify." In addition, a corporation may not elect to become a REIT
unless its taxable year is the calendar year. The Company will have a calendar
taxable year.

Ownership of a Partnership Interest. In the case of a REIT which is a
partner in a partnership, Treasury Regulations provide that the REIT will be
deemed to own its proportionate share of the assets of the partnership and
will be deemed to be entitled to the income of the partnership attributable to
such share. In addition, the character of the assets and gross income of the
partnership shall retain the same character in the hands of the REIT for
purposes of Section 856 of the Code, including satisfying the gross income
tests and the asset tests. Thus, the Company's proportionate share of the
assets and items of income of the Operating Partnership (including the
Operating Partnership's share of such items of any subsidiary partnerships)
will be treated as assets and items of income of the Company for purposes of
applying the requirements described herein. A summary of the rules governing
the federal income taxation of partnerships and their partners is provided
below in "--Tax Aspects of the Partnerships." The Company has direct control
of the Operating Partnership and operates it consistent with the requirements
for qualification as a REIT.

Ownership of Qualified REIT Subsidiaries. A corporation will qualify as a
"qualified REIT subsidiary" if 100% of its stock is held by the Company at all
times during the period which such corporation is in existence. The Company's
ownership of the stock of the Finance Company has satisfied this test and,
accordingly, the Finance Company will qualify as a qualified REIT subsidiary.
A qualified REIT subsidiary will not be treated as a separate corporation, and
all assets, liabilities, and items of income, deduction, and credit of a
qualified REIT subsidiary will be treated as assets, liabilities and such
items (as the case may be) of the Company for all purposes of the Code
including the REIT qualification tests. For this reason, references under
"Federal Income Tax Considerations" to the income and assets of the Company
include the income and assets of the Finance Company. A qualified REIT
subsidiary will not be subject to federal income tax and the Company's
ownership of the voting stock of such a subsidiary will not violate the
restrictions against ownership of securities of any one issuer which
constitute more than 10% of such issuer's voting securities or more than 5% of
the value of the Company's total assets, described below under "--Asset
Tests."

Income Tests. In order to maintain its qualification as a REIT, the Company
annually must satisfy three gross income requirements. First, at least 75% of
the Company's gross income (excluding gross income from prohibited
transactions) for each taxable year must be derived directly or indirectly
from investments relating to real property or mortgages on real property
(including "rents from real property" and, in certain circumstances, interest)
or from certain types of temporary investments. Second, at least 95% of the
Company's gross income (excluding gross income from prohibited transactions)
for each taxable year must be derived from such real property investments,
dividends, interest and gain from the sale or disposition of stock or
securities (or from any combination of the foregoing). Third, for taxable
years beginning prior to January 1, 1998, subject to certain exceptions in the
year in which the Company is liquidated, short-term gain from the sale or
other disposition of stock or securities, gain from prohibited transactions
and gain on the sale or other disposition of real property held for less than
four years (apart from involuntary conversions and sales of foreclosure
property) must represent less than 30% of the Company's gross income
(including gross income from prohibited transactions) for each taxable year.
For purposes of applying the 30% gross income test, the holding period of
Properties acquired by the Operating Partnership in the Formation Transactions
will be deemed to have commenced on the date of acquisition. See "--Tax
Legislation."

Rents received by the Company will qualify as "rents from real property" in
satisfying the gross income requirements for a REIT described above only if
several conditions are met. First, the amount of rent must not be based in
whole or in part on the income or profits of any person. However, an amount
received or accrued generally will not be excluded from the term "rents from
real property" solely by reason of being based on a fixed percentage or
percentages of receipts or sales. Second, the Code provides that rents
received from a tenant will not qualify as "rents from real property" in
satisfying the gross income tests if the REIT, or an actual or constructive

157
<PAGE>

owner of 10% or more of the REIT, actually or constructively owns 10% or more
of such tenant (a "Related Party Tenant"). Third, if rent attributable to
personal property, leased in connection with a lease of real property, is
greater than 15% of the total rent received under the lease, then the portion
of rent attributable to such personal property will not qualify as "rents from
real property." Finally, for rents received to qualify as "rents from real
property," the REIT generally must not operate or manage the property or
furnish or render services to the tenants of such property, other than through
an independent contractor from whom the REIT derives no revenue. The REIT may,
however, directly perform certain services that are "usually or customarily
rendered" in connection with the rental of space for occupancy only and are
not otherwise considered "rendered to the occupant" of the property. The
Company does not and will not; (i) charge rent for any property that is based
in whole or in part on the income or profits of any person (except by reason
of being based on a percentage of receipts or sales, as described above); (ii)
rent any property to a Related Party Tenant; (iii) derive rental income
attributable to personal property (other than personal property leased in
connection with the lease of real property, the amount of which is less than
15% of the total rent received under the lease); or (iv) perform services
considered to be rendered to the occupant of the property, other than through
an independent contractor from whom the Company derives no revenue.
Notwithstanding the foregoing, the Company may take certain of the actions set
forth in (i) through (iv) above to the extent such actions will not, based on
the advice of tax counsel to the Company, jeopardize the Company's tax status
as a REIT.

The Services Company receives fees in exchange for the performance of
certain development activities. Such fees do not accrue to the Company, but
the Company derives its allocable share of dividends from the Services Company
through its interest in the Operating Partnership, which qualify under the 95%
gross income test, but not the 75% gross income test.

The Operating Partnership receives fees in exchange for the performance of
certain management activities for third parties with respect to properties in
which the Operating Partnership does not own an interest, including certain of
the Option Properties. Such fees will result in nonqualifying income to the
Company under the 95% and 75% gross income tests. The Company believes that
the aggregate amount of nonqualifying income, including such fees, in any
taxable year will not exceed the limit on nonqualifying income under the gross
income tests.

The term "interest" generally does not include any amount received or
accrued (directly or indirectly) if the determination of such amount depends
in whole or in part on the income or profits of any person. However, an amount
received or accrued generally will not be excluded from the term "interest"
solely by reason of being based on a fixed percentage or percentages of
receipts or sales.

If the Company fails to satisfy one or both of the 75% or 95% gross income
tests for any taxable year, it may nevertheless qualify as a REIT for such
year if it is entitled to relief under certain provisions of the Code. These
relief provisions will be generally available if the Company's failure to meet
such tests was due to reasonable cause and not due to willful neglect, the
Company attaches a schedule of the sources of its income to its federal income
tax return, and any incorrect information on the schedule was not due to fraud
with intent to evade tax. It is not possible, however, to state whether in all
circumstances the Company would be entitled to the benefit of these relief
provisions. For example, if the Company fails to satisfy the gross income
tests because nonqualifying income that the Company intentionally incurs
exceeds the limits on such income, the IRS could conclude that the Company's
failure to satisfy the tests was not due to reasonable cause. If these relief
provisions are inapplicable to a particular set of circumstances involving the
Company, the Company would not qualify as a REIT. As discussed above in "--
Taxation of the Company--General," even if these relief provisions apply, a
100% tax would be imposed on an amount equal to (a) the gross income
attributable to the greater of the amount by which the Company failed the 75%
or 95% test multiplied by (b) a fraction intended to reflect the Company's
profitability. No similar mitigation provision provides relief if the Company
fails the 30% gross income test. In such case, the Company would cease to
qualify as a REIT.

Any gain realized by the Company on the sale of any property held as
inventory or other property held primarily for sale to customers in the
ordinary course of business (including the Company's share of any such

158
<PAGE>

gain realized by the Operating Partnership or the Finance Partnership) will be
treated as income from a prohibited transaction that is subject to a 100%
penalty tax. Such prohibited transaction income may also have an adverse
effect upon the Company's ability to satisfy the income tests for
qualification as a REIT. Under existing law, whether property is held as
inventory or primarily for sale to customers in the ordinary course of a trade
or business is a question of fact that depends on all the facts and
circumstances with respect to the particular transaction. The Operating
Partnership and the Finance Partnership hold the Properties for investment
with a view to long-term appreciation, engage in the business of acquiring,
developing, owning, and operating the Properties (and other properties) and
make such occasional sales of the Properties as are consistent with the
Operating Partnership's and the Finance Partnership's investment objectives.
There can be no assurance, however, that the IRS; might not contend that one
or more of such sales is subject to the 100% penalty tax.

Asset Tests. The Company, at the close of each quarter of its taxable year,
must also satisfy three tests relating to the nature of its assets. First, at
least 75% of the value of the Company's total assets (including its allocable
share of the assets held by partnerships in which it has a direct or indirect
interest, including the Operating Partnership and the Finance Partnership)
must be represented by real estate assets, stock or debt instruments held for
not more than one year purchased with the proceeds of a stock offering or
long-term (at least five years) public debt offering of the Company, cash,
cash items and government securities. Second, not more than 25% of the
Company's total assets may be represented by securities other than those in
the 75% asset class. Third, of the investments included in the 25% asset
class, the value of any one issuer's securities owned by the Company may not
exceed 5% of the value of the Company's total assets and the Company may not
own more than 10% of any one issuer's outstanding voting securities.

As described above, the Operating Partnership owns 100% of the non-voting
preferred stock of the Services Company, and by virtue of its ownership of
interests in the Operating Partnership, the Company is considered to own its
pro rata share of such stock. See "Structure and Formation of the Company."
The Operating Partnership does not and will not own any of the voting
securities of the Services Company, and therefore the Company will not be
considered to own more than 10% of the voting securities of the Services
Company. In addition, the Company believes (and has represented to tax counsel
to the Company for purposes of its opinion, as described above) that the value
of its pro rata share of the securities of the Services Company held by the
Operating Partnership does not exceed 5% of the total value of the Company's
assets, and will not exceed such amount in the future. Latham & Watkins, in
rendering its opinion as to the qualification of the Company as a REIT, is
relying on the representation of the Company to such effect. No independent
appraisals have been obtained to support this conclusion. There can be no
assurance that the IRS will not contend that the value of the securities of
the Services Company held by the Company (through the Operating Partnership)
exceeds the 5% value limitation.

The 5% value test must be satisfied not only on the date that the Company
(directly or through the Operating Partnership) acquires securities in the
Services Company, but also each time the Company increases its ownership of
securities of the Services Company (including as a result of increasing its
interest in the Operating Partnership as a result of Company capital
contributions to the Operating Partnership or as limited partners exercise
their redemption/exchange rights). Although the Company plans to take steps to
ensure that it satisfies the 5% value test for any quarter with respect to
which retesting is to occur, there can be no assurance that such steps will
always be successful, or will not require a reduction in the Operating
Partnership's overall interest in the Services Company.

After initially meeting the asset tests at the close of any quarter, the
Company will not lose its status as a REIT for failure to satisfy the asset
tests at the end of a later quarter solely by reason of changes in asset
values. If the failure to satisfy the asset tests results from an acquisition
of securities or other property during a quarter (including as a result of the
Company increasing its interest in the Operating Partnership), the failure can
be cured by the disposition of sufficient nonqualifying assets within 30 days
after the close of that quarter. The Company intends to maintain adequate
records of the value of its assets to ensure compliance with the asset tests
and to take such other actions within 30 days after the close of any quarter
as may be required to cure any noncompliance. If the Company fails to cure
noncompliance with the asset tests within such time period, the Company would
cease to qualify as a REIT.

<PAGE>

Annual Distribution Requirements. The Company, in order to qualify as a
REIT, is required to distribute dividends (other than capital gain dividends)
to its stockholders in an amount at least equal to (i) the sum of (a) 95% of
the Company's "REIT taxable income" (computed without regard to the dividends
paid deduction and by excluding the Company's net capital gain) and (b) 95% of
the excess of the net income, if any, from foreclosure property over the tax
imposed on such income, minus (ii) the excess of the sum of certain items of
noncash income (i.e., income attributable to leveled stepped rents, original
issue discount or purchase money debt, or a like-kind exchange that is later
determined to be taxable) over 5% of "REIT Taxable Income" as described in
clause (i)(a) above. In addition, if the Company disposes of any Built-In Gain
Asset during its Recognition Period, the Company will be required, pursuant to
Treasury Regulations which have not yet been promulgated, to distribute at
least 95% of the Built-in Gain (after tax), if any, recognized on the
disposition of such asset. Such distributions must be paid in the taxable year
to which they relate, or in the following taxable year if declared before the
Company timely files its tax return for such year and if paid on or before the
first regular dividend payment after such declaration. Such distributions are
taxable to holders of Common Stock (other than tax-exempt entities, as
discussed below) in the year in which paid, even though such distributions
relate to the prior year for purposes of the Company's 95% distribution
requirement. The amount distributed must not be preferential--i.e., each
holder of shares of Common Stock must receive the same distribution per share.
A REIT may have more than one class of capital stock, as long as distributions
within each class are pro rata and non-preferential. To the extent that the
Company does not distribute all of its net capital gain or distributes at
least 95%, but less than 100%, of its "REIT taxable income," as adjusted, it
will be subject to tax thereon at regular ordinary and capital gain corporate
tax rates. The Company currently makes timely distributions sufficient to
satisfy these annual distribution requirements. In this regard, the
Partnership Agreement authorizes the Company, as general partner, to take such
steps as may be necessary to cause the Operating Partnership to distribute to
its partners an amount sufficient to permit the Company to meet these
distribution requirements.

It is expected that the Company's REIT taxable income will be less than its
cash flow due to the allowance of depreciation and other non-cash charges in
computing REIT taxable income. Accordingly, the Company anticipates that it
will generally have sufficient cash or liquid assets to enable it to satisfy
the distribution requirements described above. It is possible, however, that
the Company, from time to time, may not have sufficient cash or other liquid
assets to meet these distribution requirements due to timing differences
between (i) the actual receipt of income and actual payment of deductible
expenses and (ii) the inclusion of such income and deduction of such expenses
in arriving at taxable income of the Company. In the event that such timing
differences occur, in order to meet the distribution requirements, the Company
may find it necessary to arrange for short-term, or possibly long-term,
borrowings, to pay dividends in the form of taxable stock dividends.

If the Company fails to meet the 95% distribution test due to certain
adjustments (e.g., an increase in the Company's income or a decrease in its
deduction for dividends paid) by reason of a judicial decision or by agreement
with the IRS, the Company may pay a "deficiency dividend" to holders of shares
of Common Stock in the taxable year of the adjustment, which dividend would
relate back to the year being adjusted. In such case, the Company would also
be required to pay interest to the IRS and would be subject to any applicable
penalty provisions.

Furthermore, if the Company should fail to distribute during each calendar
year at least the sum of (i) 85% of its REIT ordinary income for such year,
(ii) 95% of its REIT capital gain income for such year, and (iii) any
undistributed taxable income from prior periods, the Company would be subject
to a 4% excise tax on the excess of such required distribution over the
amounts actually distributed.

FAILURE TO QUALIFY

If the Company fails to qualify for taxation as a REIT in any taxable year,
and the relief provisions do not apply, the Company will be subject to tax
(including any applicable alternative minimum tax) on its taxable income at
regular corporate rates. Distributions to stockholders in any year in which
the Company fails to qualify will not be deductible by the Company nor will
they be required to be made. As a result, the Company's failure

160
<PAGE>

to qualify as a REIT would reduce the cash available for distribution by the
Company to its stockholders. In addition, if the Company fails to qualify as a
REIT, all distributions to stockholders will be taxable as ordinary income, to
the extent of the Company's current and accumulated earnings and profits, and,
subject to certain limitations of the Code, corporate distributees may be
eligible for the dividends received deduction. Unless entitled to relief under
specific statutory provisions, the Company will also be disqualified from
taxation as a REIT for the four taxable years following the year during which
qualification was lost. It is not possible to state whether in all
circumstances the Company would be entitled to such statutory relief.

TAXATION OF TAXABLE U.S. STOCKHOLDERS GENERALLY

As used herein, the term "U.S. Stockholder" means a holder of shares of
Common Stock who (for United States federal income tax purposes) (i) is a
citizen or resident of the United States, (ii) is a corporation, partnership,
or other entity created or organized in or under the laws of the United States
or of any political subdivision thereof, (iii) is an estate the income of
which is subject to United States federal income taxation regardless of its
source; or (iv) is a trust, if a court within the United States is able to
exercise primary supervision over the administration of the trust and one or
more United States fiduciaries have the authority to control all substantial
decisions of the trust.

As long as the Company qualifies as a REIT, distributions made by the
Company out of its current or accumulated earnings and profits (and not
designated as capital gain dividends) will constitute dividends taxable to its
taxable U.S. Stockholders as ordinary income. Such distributions will not be
eligible for the dividends received deduction otherwise available with respect
to dividends received by U.S. Stockholders that are corporations.
Distributions made by the Company that are properly designated by the Company
as capital gain dividends will be taxable to taxable U.S. Stockholders as
long-term capital gains (to the extent that they do not exceed the Company's
actual net capital gain for the taxable year) without regard to the period for
which a U.S. Stockholder has held his shares of Common Stock. U.S.
Stockholders that are corporations may, however, be required to treat up to
20% of certain capital gain dividends as ordinary income. To the extent that
the Company makes distributions (not designated as capital gain dividends) in
excess of its current and accumulated earnings and profits, such distributions
will be treated first as a tax-free return of capital to each U.S.
Stockholder, reducing the adjusted basis which such U.S. Stockholder has in
his shares of Common Stock for tax purposes by the amount of such distribution
(but not below zero), with distributions in excess of a U.S. Stockholder's
adjusted basis in his shares taxable as long-term capital gains (or short-term
capital gain if the shares have been held for one year or less), provided that
the shares have been held as a capital asset. Dividends declared by the
Company in October, November, or December of any year and payable to a
stockholder of record on a specified date in any such month shall be treated
as both paid by the Company and received by the stockholder on December 31st
of such year; provided that the dividend is actually paid by the Company on or
before January 31st of the following calendar year. Stockholders may not
include in their own income tax returns any net operating losses or capital
losses of the Company.

Distributions made by the Company and gain arising from the sale or exchange
by a U.S. Stockholder of shares of Common Stock will not be treated as passive
activity income, and, as a result, U.S. Stockholders generally will not be
able to apply any "passive losses" against such income or gain. Distributions
made by the Company (to the extent they do not constitute a return of capital)
generally will be treated as investment income for purposes of computing the
investment income limitation. Gain arising from the sale or other disposition
of Common Stock, however, will not be treated as investment income unless the
U.S. Stockholder elects to reduce the amount of such U.S. Stockholder's total
net capital gain eligible for the maximum capital gains rate by the amount of
such gain with respect to such Common Stock.

Upon any sale or other disposition of Common Stock, a U.S. Stockholder will
recognize gain or loss for federal income tax purposes in an amount equal to
the difference between (i) the amount of cash and the fair market value of any
property received on such sale or other disposition and (ii) the holder's
adjusted basis in such shares of Common Stock for tax purposes. Such gain or
loss will be capital gain or loss if the shares have been held by the U.S.
Stockholder as a capital asset, and will be long-term gain or loss if such
shares have been

161
<PAGE>

held for more than one year. In general, any loss recognized by a U.S.
Stockholder upon the sale or other disposition of shares of Common Stock that
have been held for six months or less (after applying certain holding period
rules) will be treated as a long-term capital loss, to the extent of capital
gain dividends received by such U.S. Stockholder from the Company which were
required to be treated as long-term capital gains.

BACKUP WITHHOLDING

The Company reports to its U.S. Stockholders and the IRS the amount of
dividends paid during each calendar year, and the amount of tax withheld, if
any. Under the backup withholding rules, a stockholder may be subject to
backup withholding at the rate of 31% with respect to dividends paid unless
such holder (a) is a corporation or comes within certain other exempt
categories and, when required, demonstrates this fact, or (b) provides a
taxpayer identification number, certifies as to no loss of exemption from
backup withholding, and otherwise complies with applicable requirements of the
backup withholding rules. A U.S. Stockholder that does not provide the Company
with his correct taxpayer identification number may also be subject to
penalties imposed by the IRS. Backup withholding is not an additional tax. Any
amount paid as backup withholding will be creditable against the stockholder's
income tax liability. In addition, the Company may be required to withhold a
portion of capital gain distributions to any stockholders who fail to certify
their non-foreign status to the Company. See "--Taxation of Non-U.S.
Stockholders."

TAXATION OF TAX-EXEMPT STOCKHOLDERS

The IRS has ruled that amounts distributed as dividends by a qualified REIT
do not constitute unrelated business taxable income ("UBTI") when received by
a tax-exempt entity. Based on that ruling, provided that a tax-exempt
shareholder (except certain tax-exempt shareholders described below) has not
held its shares of Common Stock as "debt financed property" within the meaning
of the Code and such shares are not otherwise used in a trade or business, the
dividend income from the Company will not be UBTI to a tax-exempt shareholder.
Similarly, income from the sale of Common Stock will not constitute UBTI
unless such tax-exempt shareholder has held such shares as "debt financed
property" within the meaning of the Code or has used the shares in a trade or
business.

For tax-exempt shareholders which are social clubs, voluntary employee
benefit associations, supplemental unemployment benefit trusts, and qualified
group legal services plans exempt from federal income taxation under Code
Sections 501(c)(7), (c)(9), (c)(17) and (c)(20), respectively, income from an
investment in the Company will constitute UBTI unless the organization is able
to properly deduct amounts set aside or placed in reserve for certain purposes
so as to offset the income generated by its investment in the Company. Such
prospective investors should consult their own tax advisors concerning these
"set aside" and reserve requirements.

Notwithstanding the above, however, a portion of the dividends paid by a
"pension held REIT" shall be treated as UBTI as to any trust which (i) is
described in Section 401(a) of the Code, (ii) is tax-exempt under Section
501(a) of the Code, and (iii) holds more than 10% (by value) of the interests
in the REIT. Tax-exempt pension funds that are described in Section 401(a) of
the Code are referred to below as "qualified trusts." A REIT is a "pension
held REIT" if (i) it would not have qualified as a REIT but for the fact that
Section 856(h)(3) of the Code provides that stock owned by qualified trusts
shall be treated, for purposes of the "not closely held" requirement, as owned
by the beneficiaries of the trust (rather than by the trust itself), and (ii)
either (a) at least one such qualified trust holds more than 25% (by value) of
the interests in the REIT, or (b) one or more such qualified trusts, each of
which owns more than 10% (by value) of the interests in the REIT, hold in the
aggregate more than 50% (by value) of the interests in the REIT. The
percentage of any REIT dividend treated as UBTI is equal to the ratio of (i)
the UBTI earned by the REIT (treating the REIT as if it were a qualified trust
and therefore subject to tax on UBTI) to (ii) the total gross income of the
REIT. A de minimis exception applies where the percentage is less than 5% for
any year. The provisions requiring qualified trusts to treat a portion of REIT
distributions as UBTI will not apply if the REIT is able to satisfy the "not
closely held" requirement without relying upon the "look-through" exception
with respect to qualified trusts. As a result of certain limitations on
transfer and ownership of Common Stock contained in the Articles of
Incorporation, the Company does not expect to be classified as a "pension held
REIT."

TAXATION OF NON-U.S. STOCKHOLDERS

The rules governing United States federal income taxation of the ownership
and disposition of stock by persons that are, for purposes of such taxation,
nonresident alien individuals, foreign corporations, foreign partnerships or
foreign estates or trusts (collectively, "Non-U.S. Stockholders") are complex,
and no attempt is made herein to provide more than a brief summary of such
rules. Accordingly, the discussion does not address all aspects of United
States federal income tax and does not address state, local or foreign tax
consequences that may be relevant to a Non-U.S. Stockholder in light of its
particular circumstances, including, for example, if the investment in the
Company is connected to the conduct by a Non-U.S. Stockholder of a U.S. trade
or business. In addition, this discussion is based on current law, which is
subject to change, and assumes that the Company qualifies for taxation as a
REIT. Prospective Non-U.S. Stockholders should consult with their own tax
advisers to determine the impact of federal, state, local and foreign income
tax laws with regard to an investment in Common Stock, including any reporting
requirements.

Distributions. Distributions by the Company to a Non-U.S. Stockholder that
are neither attributable to gain from sales or exchanges by the Company of
United States real property interests nor designated by the Company as capital
gains dividends will be treated as dividends of ordinary income to the extent
that they are made out of current or accumulated earnings and profits of the
Company. Such distributions ordinarily will be subject to withholding of
United States federal income tax on a gross basis (that is, without allowance
of deductions) at a 30% rate or such lower rate as may be specified by an
applicable income tax treaty, unless the dividends are treated as effectively
connected with the conduct by the Non-U.S. Stockholder of a United States
trade or business. Dividends that are effectively connected with such a trade
or business will be subject to tax on a net basis (that is, after allowance of
deductions) at graduated rates, in the same manner as domestic stockholders
are taxed with respect to such dividends and are generally not subject to
withholding. Any such dividends received by a Non-U.S. Stockholder that is a
corporation may also be subject to an additional branch profits tax at a 30%
rate or such lower rate as may be specified by an applicable income tax
treaty.

Pursuant to current Treasury Regulations, dividends paid to an address in a
country outside the United States are generally presumed to be paid to a
resident of such country for purposes of determining the applicability of
withholding discussed above and the applicability of a tax treaty rate. Under
proposed Treasury Regulations, not currently in effect, however, a Non-U.S.
Stockholder who wished to claim the benefit of an applicable treaty rate would
be required to satisfy certain certification and other requirements. Under
certain treaties, lower withholding rates generally applicable to dividends do
not apply to dividends from a REIT, such as the Company. Certain certification
and disclosure requirements must be satisfied to be exempt from withholding
under the effectively connected income exemption discussed above.

Distributions in excess of current or accumulated earnings and profits of
the Company will not be taxable to a Non-U.S. Stockholder to the extent that
they do not exceed the adjusted basis of the stockholder's Common Stock, but
rather will reduce the adjusted basis of such stock. For FIRPTA withholding
purposes (discussed below), such distributions (i.e., distributions that are
not made out of earnings and profits) will be treated as consideration for the
sale or exchange of shares of Common Stock. To the extent that such
distributions exceed the adjusted basis of a Non-U.S. Stockholder's Common
Stock, they will give rise to gain from the sale or exchange of his stock, the
tax treatment of which is described below. If it cannot be determined at the
time a distribution is made whether or not such distribution will be in excess
of current or accumulated earnings and profits, the distribution will
generally be treated as a dividend for withholding purposes. However, amounts
thus withheld are generally refundable if it is subsequently determined that
such distribution was, in fact, in excess of current or accumulated earnings
and profits of the Company.

Distributions to a Non-U.S. Stockholder that are designated by the Company
at the time of distribution as capital gains dividends (other than those
arising from the disposition of a United States real property interest)
generally will not be subject to United States federal income taxation, unless
(i) investment in the Common Stock is effectively connected with the Non-U.S.
Stockholder's United States trade or business, in which case the Non-U.S.
Stockholder will be subject to the same treatment as domestic stockholders
with respect to such gain (except

163
<PAGE>

that a stockholder that is a foreign corporation may also be subject to the
30% branch profits tax, as discussed above), or (ii) the Non-U.S. Stockholder
is a nonresident alien individual who is present in the United States for 183
days or more during the taxable year and has a"tax home" in the United States,
in which case the nonresident alien individual will be subject to a 30% tax on
the individual's capital gains.

Distributions to a Non-U.S. Stockholder that are attributable to gain from
sales or exchanges by the Company of United States real property interests
will cause the Non-U.S. Stockholder to be treated as recognizing such gain as
income effectively connected with a United States trade or business. Non-U.S.
Stockholders would thus generally be entitled to offset its gross income by
allowable deductions and would pay tax on the resulting taxable income at the
same rates applicable to domestic stockholders (subject to a special
alternative minimum tax in the case of nonresident alien individuals). Also,
such gain may be subject to a 30% branch profits tax in the hands of a Non-
U.S. Stockholder that is a corporation and is not entitled to treaty relief or
exemption, as discussed above. The Company is required to withhold 35% of any
such distribution. That amount is creditable against the Non-U.S.
Stockholder's United States federal income tax liability. To the extent that
such withholding exceeds the actual tax owed by the Non-U.S. Stockholder, the
Non-U.S. Stockholder may claim a refund from the IRS.

The Company or any nominee (e.g., a broker holding shares in street name)
may rely on a certificate of non-foreign status on Form W-8 or Form W-9 to
determine whether withholding is required on gains realized from the
disposition of United States real property interests. A domestic person who
holds shares of Common Stock on behalf of a Non-U.S. Stockholder will bear the
burden of withholding, provided that the Company has properly designated the
appropriate portion of a distribution as a capital gain dividend.

Sale of Common Stock. Gain recognized by a Non-U.S. Stockholder upon the
sale or exchange of shares of Common Stock generally will not be subject to
United States taxation unless such shares constitute a"United States real
property interest" within the meaning of the Foreign Investment in Real
Property Tax Act of 1980 ("FIRPTA"). The Common Stock will not constitute
a"United States real property interest" so long as the Company is
a"domestically controlled REIT." A"domestically controlled REIT" is a REIT in
which at all times during a specified testing period less than 50% in value of
its stock is held directly or indirectly by Non-U.S. Stockholders. The Company
believes that is a"domestically controlled REIT," and therefore that the sale
of shares of Common Stock are not subject to taxation under FIRPTA. However,
because the shares of Common Stock are publicly traded, no assurance can be
given that the Company will continue to be a"domestically-controlled REIT."
Notwithstanding the foregoing, gain from the sale or exchange of shares of
Common Stock not otherwise subject to FIRPTA will be taxable to a Non-U.S.
Stockholder if the Non-U.S. Stockholder is a nonresident alien individual who
is present in the United States for 183 days or more during the taxable year
and has a"tax home" in the United States. In such case, the nonresident alien
individual will be subject to a 30% United States withholding tax on the
amount of such individual's gain.

If the Company does not qualify as or ceases to be a"domestically-controlled
REIT," gain arising from the sale or exchange by a Non-U.S. Stockholder of
shares of Common Stock would be subject to United States taxation under FIRPTA
as a sale of a"United States real property interest" unless the shares
are"regularly traded" (as defined by applicable Treasury Regulations) on an
established securities market (e.g., the New York Stock Exchange) and the
selling Non-U.S. Stockholder held no more than 5% (after applying certain
constructive ownership rules) of the shares of Common Stock during the shorter
of (i) the period during which the taxpayer held such shares, or (ii) the 5-
year period ending on the date of the disposition of such shares. If gain on
the sale or exchange of shares of Common Stock were subject to taxation under
FIRPTA, the Non-U.S. Stockholder would be subject to regular United States
income tax with respect to such gain in the same manner as a U.S. Stockholder
(subject to any applicable alternative minimum tax, a special alternative
minimum tax in the case of nonresident alien individuals and the possible
application of the 30% branch profits tax in the case of foreign
corporations), and the purchaser of the stock would be required to withhold
and remit to the IRS 10% of the purchase price.

Backup Withholding Tax and Information Reporting. Backup withholding tax
(which generally is a withholding tax imposed at the rate of 31% on certain
payments to persons that fail to furnish certain information under the United
States information reporting requirements) and information reporting will
generally not apply to distributions paid to Non-U.S. Stockholders outside the
United States that are treated as (i) dividends subject to the 30% (or lower
treaty rate) withholding tax discussed above, (ii) capital gains dividends or
(iii) distributions attributable to gain from the sale or exchange by the
Company of United States real property interests. As a general matter, backup
withholding and information reporting will not apply to a payment of the
proceeds of a sale of Common Stock by or through a foreign office of a foreign
broker. Information reporting (but not backup withholding) will apply,
however, to a payment of the proceeds of a sale of Common Stock by a foreign
office of a broker that (a) is a United States person, (b) derives 50% or more
of its gross income for certain periods from the conduct of a trade or
business in the United States or (c) is a "controlled foreign corporation"
(generally, a foreign corporation controlled by United States stockholders)
for United States tax purposes, unless the broker has documentary evidence in
its records that the holder is a Non-U.S. Stockholder and certain other
conditions are met, or the stockholder otherwise establishes an exemption.
Payment to or through a United States office of a broker of the proceeds of a
sale of Common Stock is subject to both backup withholding and information
reporting unless the stockholder certifies under penalty of perjury that the
stockholder is a Non-U.S. Stockholder, or otherwise establishes an exemption.
Backup withholding is not additional tax. A Non-U.S. Stockholder may obtain a
refund of any amounts withheld under the backup withholding rules by filing
the appropriate claim for refund with the IRS.

New Proposed Regulations. The United States Treasury has recently issued
proposed Treasury Regulations regarding the withholding and information
reporting rules discussed above. In general, the proposed Treasury Regulations
create new withholding and information reporting requirements and
certification procedures and forms and clarify and modify reliance standards.
If finalized in their current form, the proposed Treasury Regulations would
generally be effective for payments made after December 31, 1997, subject to
certain transition rules.

TAX ASPECTS OF THE PARTNERSHIPS

General. Substantially all of the Company's investments are held indirectly
through the Operating Partnership and the Finance Partnership. In general,
partnerships are "pass-through" entities which are not subject to federal
income tax. Rather, partners are allocated their proportionate shares of the
items of income, gain, loss, deduction and credit of a partnership, and are
potentially subject to tax thereon, without regard to whether the partners
receive a distribution from the partnership. The Company includes in its
income its proportionate share of the foregoing partnership items for purposes
of the various REIT income tests and in the computation of its REIT taxable
income. Moreover, for purposes of the REIT asset tests, the Company includes
its proportionate share of assets held by the Operating Partnership. See "--
Taxation of the Company."

Entity Classification. The Company's interests in the Operating Partnership
and the Finance Partnership involve special tax considerations, including the
possibility of a challenge by the IRS of the status of the Operating
Partnership or the Finance Partnership as a partnership (as opposed to an
association taxable as a corporation) for federal income tax purposes. If the
Operating Partnership or the Finance Partnership were treated as an
association, it would be taxable as a corporation and therefore be subject to
an entity-level tax on its income. In such a situation, the character of the
Company's assets and items of gross income would change and preclude the
Company from satisfying the asset tests and possibly the income tests (see "--
Taxation of the Company--Asset Tests" and "--Income Tests"), and in turn would
prevent the Company from qualifying as a REIT. See "--Taxation of the
Company--Failure to Qualify" above for a discussion of the effect of the
Company's failure to meet such tests for a taxable year. In addition, a change
in the Operating Partnership's or Finance Partnership's status for tax
purposes might be treated as a taxable event in which case the Company might
incur a tax liability without any related cash distributions.

The IRS recently finalized and published certain Treasury Regulations (the
"Final Regulations") which provide that a domestic business entity not
otherwise classified as a corporation and which has at least two members (an
"Eligible Entity") may elect to be taxed as a partnership for federal income
tax purposes. The Final

165
<PAGE>

Regulations apply for tax periods beginning on or after January 1, 1997 (the
"Effective Date"). Unless it elects otherwise, an Eligible Entity in existence
prior to the Effective Date will have the same classification for federal
income tax purposes that it claimed under the entity classification Treasury
Regulations in effect prior to the Effective Date. In addition, an Eligible
Entity which did not exist, or did not claim a classification, prior to the
Effective Date, will be classified as a partnership for federal income tax
purposes unless it elects otherwise. Each of the Operating Partnership and
Finance Partnership intends to claim classification as a partnership under the
Final Regulations.

Partnership Allocations. Although a partnership agreement will generally
determine the allocation of income and loss among partners, such allocations
will be disregarded for tax purposes if they do not comply with the provisions
of Section 704(b) of the Code and the Treasury Regulations promulgated
thereunder. Generally, Section 704(b) and the Treasury Regulations promulgated
thereunder require that partnership allocations respect the economic
arrangement of the partners.

If an allocation is not recognized for federal income tax purposes, the item
subject to the allocation will be reallocated in accordance with the partners'
interests in the partnership, which will be determined by taking into account
all of the facts and circumstances relating to the economic arrangement of the
partners with respect to such item. The Operating Partnership's allocations of
taxable income and loss are intended to comply with the requirements of
Section 704(b) of the Code and the Treasury Regulations promulgated
thereunder.

The Partnership Agreement provides that net income or net loss of the
Operating Partnership will generally be allocated to the Company and the
limited partners in accordance with their respective percentage interests in
the Operating Partnership. Notwithstanding the foregoing, such agreement
provides that certain interest deductions and income from the discharge of
certain indebtedness of the Operating Partnership, attributable to loans
transferred to the Operating Partnership by certain Unitholders, will be
allocated disproportionately to such Unitholders. In addition, allocations of
net income or net loss are subject to compliance with the provisions of
Sections 704(b) and 704(c) of the Code and the Treasury Regulations
promulgated thereunder.

Tax Allocations with Respect to the Properties. Pursuant to Section 704(c)
of the Code, income, gain, loss and deduction attributable to appreciated or
depreciated property (such as the Properties) that is contributed to a
partnership in exchange for an interest in the partnership, must be allocated
in a manner such that the contributing partner is charged with, or benefits
from, respectively, the unrealized gain or unrealized loss associated with the
property at the time of the contribution. The amount of such unrealized gain
or unrealized loss is generally equal to the difference between the fair
market value of contributed property at the time of contribution and the
adjusted tax basis of such property at such time (a "Book-Tax Difference").
Such allocations are solely for federal income tax purposes and do not affect
the book capital accounts or other economic or legal arrangements among the
partners. The Operating Partnership was formed by way of contributions of
appreciated property (including certain Properties). Consequently, the
Partnership Agreement requires that such allocations be made in a manner
consistent with Section 704(c) of the Code.

In general, the principals of KI and possibly other Unitholders who are
limited partners of the Operating Partnership will be allocated depreciation
deductions for tax purposes which are lower than such deductions would be if
determined on a pro rata basis. In addition, in the event of the disposition
of any of the contributed assets which have a Book-Tax Difference, all income
attributable to such Book-Tax Difference will generally be allocated to such
limited partners, and the Company will generally be allocated only its share
of capital gains attributable to appreciation, if any, occurring after the
date the Operating Partnership acquired such assets. This will tend to
eliminate the Book-Tax Difference over the life of the Operating Partnership.
However, the special allocation rules of Section 704(c) do not always entirely
eliminate the Book-Tax Difference on an annual basis or with respect to a
specific taxable transaction such as a sale. Thus, the carryover basis of the
contributed assets in the hands the Operating Partnership may cause the
Company to be allocated lower depreciation and other deductions, and possibly
an amount of taxable income in the event of a sale of such contributed assets
in excess of the economic or book income allocated to it as a result of such
sale. This may cause the Company to recognize taxable income in excess of cash
proceeds, which might adversely affect the Company's ability to comply with
the REIT distribution requirements. See "--Taxation of the Company--Annual
Distribution Requirements."

166
<PAGE>

Treasury Regulations under Section 704(c) of the Code provide partnerships
with a choice of several methods of accounting for Book-Tax Differences,
including retention of the "traditional method" or the election of certain
methods which would permit any distortions caused by a Book-Tax Difference to
be entirely rectified on an annual basis or with respect to a specific taxable
transaction such as a sale. The Operating Partnership Agreement provides that
it will use the traditional method with respect to the assets it acquired at
the time of the IPO. The selection of this method will cause the Company to be
allocated depreciation deductions for tax purposes which are lower than such
deductions would be if the Company directly had acquired its pro rata share of
the Operating Partnership property in exchange for cash or if other methods
were chosen to eliminate Book-Tax Differences. The Operating Partnership and
the Company have not yet decided which method will be used to account for
Book-Tax Differences with respect to properties acquired or to be acquired by
the Operating Partnership after the IPO.

With respect to any property purchased by the Operating Partnership in a
taxable transaction (e.g., properties acquired in exchange for cash)
subsequent to the admission of the Company to the Operating Partnership, such
property will initially have a tax basis equal to its fair market value, and
Section 704(c) of the Code will not apply.

SERVICES COMPANY

A portion of the cash to be used by the Operating Partnership to fund
distributions to partners, and in turn to fund distributions by the Company to
its stockholders, is expected to come from the Services Company, through
dividends on nonvoting preferred stock to be held by the Operating
Partnership. The Services Company will not qualify as a REIT and will pay
federal, state and local income taxes on its taxable income at normal
corporate rates. The federal, state and local income taxes that the Services
Company is required to pay will reduce the cash available for distribution by
the Company to its stockholders.

As described above, the value of the Company's indirect interest in the
securities of the Services Company held by the Operating Partnership cannot
exceed 5% of the value of the Company's total assets at the end of any
calendar quarter in which the Company acquires such securities or increases
its interest in such securities (including as a result of the Company
increasing its interest in the Operating Partnership). See "--Taxation of the
Company--Asset Tests." This limitation may restrict the ability of the
Services Company to increase the size of its business, or may cause the
Operating Partnership to sell all or a portion of its stock in the Services
Company, unless the value of the assets of the Company or the Operating
Partnership is increasing at a commensurate rate.

TAX LEGISLATION

On August 5, 1997, President Clinton signed into law the Taxpayer Relief Act
of 1997 (H.R. 2014), which will have the effect of modifying certain REIT-
related Code provisions for tax years beginning on or after January 1, 1998.
Some of the potentially significant REIT-related changes contained in this
legislation include: (i) the rule disqualifying a REIT for any year in which
it fails to comply with certain regulations requiring the REIT to monitor its
stock ownership is replaced with an intermediate financial penalty; (ii) the
rule disqualifying a REIT in any year that it is "closely held" does not apply
if during such year the REIT complied with certain regulations which require
the REIT to monitor its stock ownership, and the REIT did not know or have
reason to know that it was closely held; (iii) a REIT is permitted to render a
de minimis amount of impermissible services to tenants in connection with the
management of property and still treat amounts received with respect to such
property (other than certain amounts relating to such services) as qualified
rent; (iv) the 30% gross income test is repealed; (v) any corporation wholly-
owned by a REIT is permitted to be treated as a qualified REIT subsidiary
regardless of whether such subsidiary has always been owned by the REIT; and
(vi) certain other Code provisions relating to REITs are amended. Some or all
of the provisions could affect both the Company's operations and its ability
to maintain its REIT status for its taxable years beginning in 1998.

167

OTHER TAX CONSEQUENCES

The Company and its stockholders may be subject to state or local taxation
in various state or local jurisdictions, including those in which it or they
transact business or reside. The state and local tax treatment of the Company
and its stockholders may not conform to the federal income tax consequences
discussed above. Consequently, prospective stockholders should consult their
own tax advisors regarding the effect of state and local tax laws on an
investment in the Company.

ERISA CONSIDERATIONS

The following is a summary of material considerations arising under ERISA
and the prohibited transaction provisions of Section 4975 of the Code that may
be relevant to a prospective purchaser (including, with respect to the
discussion contained in "--Status of the Company, the Operating Partnership
and the Services Company under ERISA," to a prospective purchaser that is not
an employee benefit plan, another tax-qualified retirement plan or an
individual retirement account ("IRA")). This discussion does not propose to
deal with all aspects of ERISA or Section 4975 of the Code or, to the extent
not preempted, state law that may be relevant to particular employee benefit
plan shareholders (including plans subject to Title I of ERISA, other employee
benefit plans and IRAs subject to the prohibited transaction provisions of
Section 4975 of the Code, and governmental plans and church plans that are
exempt from ERISA and Section 4975 of the Code but that may be subject to
state law requirements) in light of their particular circumstances.

A FIDUCIARY MAKING THE DECISION TO INVEST IN SHARES OF COMMON STOCK ON
BEHALF OF A PROSPECTIVE PURCHASER WHICH IS AN ERISA PLAN, A TAX-QUALIFIED
RETIREMENT PLAN, AN IRA OR OTHER EMPLOYEE BENEFIT PLAN IS ADVISED TO CONSULT
ITS OWN LEGAL ADVISOR REGARDING THE SPECIFIC CONSIDERATIONS ARISING UNDER
ERISA, SECTION 4975 OF THE CODE, AND (TO THE EXTENT NOT PRE-EMPTED) STATE LAW
WITH RESPECT TO THE PURCHASE, OWNERSHIP OR SALE OF SHARES OF COMMON STOCK BY
SUCH PLAN OR IRA. Plans should also consider the entire discussion under the
heading "Federal Income Tax Considerations," as material contained therein is
relevant to any decision by an employee benefit plan, tax-qualified retirement
plan or IRA to purchase the Common Stock.

EMPLOYEE BENEFIT PLANS, TAX-QUALIFIED RETIREMENT PLANS AND IRAS

Each fiduciary of an employee benefit plan subject to Title I of ERISA (an
"ERISA Plan") should carefully consider whether an investment in shares of
Common Stock is consistent with its fiduciary responsibilities under ERISA. In
particular, the fiduciary requirements of Part 4 of Title I of ERISA require
(i) an ERISA Plan's investments to be prudent and in the best interests of the
ERISA Plan, its participants and beneficiaries, (ii) an ERISA Plan's
investments to be diversified in order to reduce the risk of large losses,
unless it is clearly prudent not to do so, (iii) an ERISA Plan's investments
to be authorized under ERISA and the terms of the governing documents of the
ERISA Plan and (iv) that the fiduciary not cause the ERISA Plan to enter into
transactions prohibited under Section 406 of ERISA. In determining whether an
investment in shares of Common Stock is prudent for purposes of ERISA, the
appropriate fiduciary of an ERISA Plan should consider all of the facts and
circumstances, including whether the investment is reasonably designed, as a
part of the ERISA Plan's portfolio for which the fiduciary has investment
responsibility, to meet the objectives of the ERISA Plan, taking into
consideration the risk of loss and opportunity for gain (or other return) from
the investment, the diversification, cash flow and funding requirements of the
ERISA Plan, and the liquidity and current return of the ERISA Plan's
portfolio. A fiduciary should also take into account the nature of the
Company's business, the length of the Company's operating history and other
matters described under "Risk Factors."

The fiduciary of an IRA or of an employee benefit plan not subject to Title
I of ERISA because it is a governmental or church plan or because it does not
cover common law employees (a "Non-ERISA Plan") should

168
<PAGE>

consider that such an IRA or Non-ERISA Plan may only make investments that are
authorized by the appropriate governing documents, not prohibited under
Section 4975 of the Code and permitted under applicable state law.

STATUS OF THE COMPANY, THE OPERATING PARTNERSHIP AND THE SERVICES COMPANY
UNDER ERISA

A prohibited transaction may occur if the assets of the Company are deemed
to be assets of the investing Plans and disqualified persons deal with such
assets. In certain circumstances where a Plan holds an interest in an entity,
the assets of the entity are deemed to be Plan assets (the "look-through
rule"). Under such circumstances, any person that exercises authority or
control with respect to the management or disposition of such assets is a Plan
fiduciary. Plan assets are not defined in ERISA or the Code, but the United
States Department of Labor has issued regulations, effective March 13, 1987
(the "Regulations"), that outline the circumstances under which a Plan's
interest in an entity will be subject to the look-through rule.

The Regulations apply only to the purchase by a Plan of an "equity interest"
in an entity, such as common stock of a REIT. However, the Regulations provide
an exception to the look-through rule for equity interests that are "publicly-
offered securities."

Under the Regulations, a "publicly-offered security" is a security that is
(i) freely transferable, (ii) part of a class of securities that is widely-
held and (iii) either (a) part of a class of securities that is registered
under section 12(b) or 12(g) of the Exchange Act or (b) sold to a Plan as part
of an offering of securities to the public pursuant to an effective
registration statement under the Securities Act and the class of securities of
which such security is a part is registered under the Exchange Act within 120
days (or such longer period allowed by the Securities and Exchange Commission)
after the end of the fiscal year of the issuer during which the offering of
such securities to the public occurred. Whether a security is considered
"freely transferable" depends on the facts and circumstances of each case.
Generally, if the security is part of an offering in which the minimum
investment is $10,000 or less, any restriction on or prohibition against any
transfer or assignment of such security for the purposes of preventing a
termination or reclassification of the entity for federal or state tax
purposes will not of itself prevent the security from being considered freely
transferable. A class of securities is considered "widely-held" if it is a
class of securities that is owned by 100 or more investors independent of the
issuer and of one another.

The Common Stock of the Company meets the criteria of the publicly-offered
securities exception to the look-through rule. First, the Common Stock is
considered to be freely transferable, as the minimum investment will be less
than $10,000 and the only restrictions upon its transfer are those required
under federal tax laws to maintain the Company's status as a REIT. Second, the
Common Stock is held by 100 or more investors and that at least 100 or more of
these investors are independent of the Company and of one another. Third, the
Common Stock is part of an offering of securities to the public pursuant to an
effective registration statement under the Securities Act and is registered
under the Exchange Act within 120 days after the end of the fiscal year of the
Company during which the offering of such securities to the public occurs.
Accordingly, the Company believes that if a Plan purchases the Common Stock,
the Company's assets should not be deemed to be Plan assets and, therefore,
that any person who exercises authority or control with respect to the
Company's assets should not be a Plan fiduciary.

UNDERWRITING

The Underwriters named below (the "Underwriters") have severally agreed,
subject to the terms and conditions contained in the Underwriting Agreement,
to purchase from the Company the number of shares of Common Stock set forth
below opposite their respective names:

<TABLE>
<CAPTION>

Prudential Securities Incorporated................................ 1,666,670
Donaldson, Lufkin & Jenrette Securities Corporation............... 1,666,666

----------
Total........................................................... 10,000,000
==========
</TABLE>

The Company is obligated to sell, and the Underwriters are obligated to
purchase, all of the shares of Common Stock offered hereby if any are
purchased.

The Underwriters have advised the Company that they propose to offer the
shares of Common Stock to the public initially at the public offering price
set forth on the cover page of this Prospectus; that the Underwriters may
allow to selected dealers a concession of $0.74 per share, and that such
dealers may re-allow a concession of $0.10 per share to certain other dealers.
After the Offering, the Offering Price and the concessions may be changed by
the Underwriters.

The Company has granted the Underwriters an option, exercisable for 30 days
from the date of this Prospectus, to purchase up to 1,500,000 additional
shares of Common Stock at the initial public offering price, less the
underwriting discounts and commissions, as set forth on the cover page of this
Prospectus. The Underwriters may exercise such option solely for the purpose
of covering over-allotments incurred in the sale of shares of Common Stock
offered hereby. To the extent such option to purchase is exercised, each
Underwriter will become obligated, subject to certain conditions, to purchase
approximately the same percentage of such additional shares of Common Stock as
the number set forth next to such Underwriter's name in the preceding table
bears to 10,000,000.

The Company has agreed to indemnify the several Underwriters against or to
contribute to losses arising out of certain liabilities, including liabilities
under the Securities Act. The Company has been advised that, in the opinion of
the Commission, such indemnification is against public policy as expressed in
the Securities Act and is, therefore, unenforceable. Nevertheless, the
Underwriters may seek to enforce such indemnification and rights to
contribution which are expressly provided under the Act.

The Company has agreed not to, directly or indirectly, offer, sell, offer to
sell, contract to sell, pledge, grant any option to purchase or otherwise
dispose or transfer (or announce any offer, sale, offer of sale, contract of
sale, pledge, grant of any option to purchase or other disposition or
transfer) of any (other than pursuant to the Stock Incentive Plan) Units or
shares of Common Stock or other capital stock of the Company, or of securities
substantially similar thereto, or any other securities convertible into, or
exercisable or exchangeable for, any Units or shares of Common Stock or other
capital stock of the Company, or such similar securities, for a period of
180 days from the date of the Prospectus, in each case without the prior
written consent of Prudential Securities, on behalf of the Underwriters,
subject to certain limited exceptions.

All but four of the Unitholders (who hold an aggregate of 165,102 Units)
have agreed not to, directly or indirectly, offer, sell, offer to sell,
contract to sell, pledge, grant any option to purchase or otherwise dispose or

170
<PAGE>

transfer (or announce any offer, sale, offer of sale, contract of sale,
pledge, grant of any option to purchase or other disposition or transfer) of
any Units or shares of Common Stock or other capital stock of the Company, or
any securities convertible or exercisable or exchangeable for any Units or
shares of Common Stock or other capital stock of the Company, or any
securities substantially similar thereto, for a period of two years from
January 28, 1997, and four Unitholders who hold a total of 165,102 limited
partnership Units agreed in connection with the issuance of such Units not to
exchange such Units for shares of Common Stock prior to January 29, 1999.

In connection with the Offering, certain Underwriters and selling group
members (if any) and their respective affiliates may engage in transactions
that stabilize, maintain or otherwise affect the market price of the Common
Stock. Such transactions may include stabilization transactions effected in
accordance with Rule 104 of Regulation M promulgated by the Commission,
pursuant to which such persons may bid for or purchase Common Stock for the
purpose of stabilizing its market price. The Underwriters also may create a
short position for the account of the Underwriters by selling more Common
Stock in connection with the Offering than they are committed to purchase from
the Company, and in such case may purchase Common Stock in the open market
following the closing of the Offering to cover all or a portion of such short
position. The Underwriters may also cover all or a portion of such short
position, up to 1,500,000 shares of Common Stock, by exercising the
Underwriters' over-allotment option referred to above. In addition, Prudential
Securities Incorporated, on behalf of the Underwriters, may impose "penalty
bids" under contractual arrangements with the Underwriters whereby it may
reclaim from an Underwriter (or selling group member participating in the
Offering) for the account of the other Underwriters, the selling concession
with respect to Common Stock that is distributed in the Offering but
subsequently purchased for the account of the Underwriters in the open market.
Any of the transactions described in this paragraph may result in the
maintenance of the price of the Common Stock at a level above that which might
otherwise prevail in the open market. None of the transactions described in
this paragraph is required, and, if they are undertaken, they may be
discontinued at any time.

An affiliate of J.P. Morgan Securities Inc. provided the Mortgage Loans and
the Credit Facility. In connection with such transactions, the Company paid
(i) a debt placement fee to an affiliate of J.P. Morgan Securities Inc. for
(a) the $84.0 Million Loan equal to 0.5% of the principal amount thereof and
(b) the SeaTac Loan equal to 1.5% of the principal amount thereof, and (ii) an
origination fee to an affiliate of J.P. Morgan Securities Inc. for the Credit
Facility equal to 1.0% of the maximum amount available thereunder.

Prudential Securities Incorporated received approximately $31.0 million of
the net proceeds of the IPO as repayment of indebtedness, fees and related
interest. Certain of the Representatives received financial advisory fees
equal, in the aggregate, to 0.75% of the gross proceeds received by the
Company in the IPO.

The Prudential Insurance Company of America, an affiliate of Prudential
Securities Incorporated, is a tenant in one of the Office Properties located
in Kilroy Long Beach, leasing approximately 2,189 rentable square feet of
space.

In connection with the IPO, certain of the Underwriters received advisory
fees and underwriting discounts and commissions from the Company. In the
ordinary course of their business, certain of the Underwriters or their
affiliates have engaged in transactions with and performed services for the
Company and its subsidiaries for which they have received customary fees.

INDEPENDENT AUDITORS' REPORT

To the Partners of Kilroy Group:

We have audited the accompanying combined balance sheets of Kilroy Group
(described in Note 1) as of December 31, 1996 and 1995, and the related
combined statements of operations, accumulated deficit, and cash flows for
each of the three years in the period ended December 31, 1996. These financial
statements and the financial statement schedule are the responsibility of the
management of Kilroy Group. 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 generally accepted auditing
standards. Those standards require that we plan and perform our 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 Kilroy Group as of December 31, 1996 and
1995, and the results of its operations and its cash flows for each of the
three years in the period ended December 31, 1996 in conformity with generally
accepted accounting principles.

SIX MONTHS ENDED JUNE 30, 1997 AND 1996 (UNAUDITED) AND
YEARS ENDED DECEMBER 31, 1996, 1995 AND 1994

1. ORGANIZATION AND FORMATION TRANSACTIONS

Kilroy Realty Corporation (the "Company") was incorporated in Maryland in
September 1996 and is the successor to the operations of the Kilroy Group
("KG"). KG consists of the combination of Kilroy Industries ("KI") and various
entities, the properties of which were under common control of KI and/or its
stockholders, including John B. Kilroy, Sr. and John B. Kilroy, Jr. The
Company's Chairman of the Board of Directors, and President and Chief
Executive Officer are John B. Kilroy, Sr. and John B. Kilroy, Jr.,
respectively. KI has historically provided acquisition, development,
financing, construction and leasing services with respect to the properties
held by KG. KI has also provided development services to the third-party
owners of properties for a fee. The accompanying combined financial statements
of KG have been presented on a combined basis because of common ownership and
management and because the entities were the subject of a business combination
in 1997 with the Company.

On January 31, 1997, the Company completed an initial public offering of
12,500,000 shares of $.01 par value common stock. The Offering price was
$23.00 per share resulting in gross proceeds of $287,500,000. On February 7,
1997, the underwriters exercised their over-allotment option and, accordingly,
the Company issued an additional 1,875,000 shares of common stock and received
gross proceeds of $43,125,000. The aggregate proceeds to the Company, net of
underwriters' discount, advisory fee and offering costs were approximately
$302,800,000. The initial public offering, including the shares issued upon
the exercise of the underwriters over-allotment option in connection therewith
is hereinafter referred to as the "Offering."

The following transactions occurred simultaneously with the completion of
the Offering (collectively, the "Formation Transactions):

. The Company consummated various purchase agreements to acquire four
properties for approximately $58,000,000 in cash. The four properties
had aggregate operating revenues of approximately $9,100,000 and net
operating income (before depreciation, amortization and interest) of
approximately $6,300,000 during the year ended December 31, 1996.

. The Company became the sole general partner of Kilroy Realty L.P. (the
"Operating Partnership"). Upon completion of the Offering, the Company
contributed substantially all of the net proceeds of the Offering in
exchange for an approximate 84.5% interest in the Operating Partnership.
The Company also contributed cash in exchange for 100% of the capital
stock of Kilroy Realty Finance, Inc. ("Finance Inc."), which was formed
to serve as the general partner of Kilroy Realty Finance Partnership,
L.P. (the "Finance Partnership"). The Operating Partnership executed
various option and purchase agreements whereby it issued 2,652,374 units
of the Operating Partnership ("Units"), representing a 15.5% partnership
interest, to the continuing investors in exchange for their interests in
the properties listed below. The continuing investors included John B.
Kilroy Sr., John B. Kilroy Jr., certain family members and certain
entities owned by them. The Operating Partnership contributed certain
properties to the Finance Partnership in exchange for a limited
partnership interest therein. All properties acquired by the Company are
held by or through the Operating Partnership or the Finance Partnership.
Unless otherwise indicated, all references to the Company include the
Operating Partnership, the Finance Partnership and Finance Inc.

. The Finance Partnership and the Operating Partnership borrowed
$84,000,000 and $12,000,000, respectively, under two mortgage loans.

. The Operating Partnership used a portion of the Offering proceeds and
the proceeds of new mortgage borrowings to repay approximately
$219,000,000 of indebtedness.

. The Operating Partnership contributed certain assets valued at
approximately $100,000 to Kilroy Services Inc. in exchange for a 5%
ownership interest and a 95% economic interest in Kilroy Services Inc.
The remaining ownership interest is held by John B. Kilroy, Sr. and John
B. Kilroy, Jr.

The Company is engaged in the acquisition, development, ownership and
operation of office and industrial properties located in California,
Washington and Arizona. As of March 31, 1997, the Company owned and operated
14 office properties encompassing approximately 2.0 million rentable square
feet and 12 industrial properties encompassing approximately 1.3 million
rentable square feet located in Southern California, Washington and Arizona.

The entities which directly owned the properties contributed to the
Operating Partnership are as follows:

KILROY REALTY CORPORATION CONSOLIDATED
AND KILROY GROUP COMBINED

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

The development services of KG relating to non-owned properties have been
conducted by KI and Kilroy Technologies Company, LLC, both wholly-owned by
John B. Kilroy, Sr. and John B. Kilroy, Jr.

Certain of the named entities are owned by other entities. The properties
are ultimately owned beneficially in the proportions identified above.

Certain other properties and operations affiliated with KI have been
excluded as they are not compatible with the investment purposes of the
Company. Deemed and actual cash distributions to partners, net of
contributions, included in the combined statements of accumulated deficit
generally represent distributions of the cash flows generated by KG, and
advances to partners and KI, as well as related-party transactions (see Note
8).

2. BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The consolidated financial statements include the consolidated financial
position of the Company, Finance Inc., the Finance Partnership and the
Operating Partnership at March 31, 1997 and the results of their operations
for the period from February 1, 1997 to March 31, 1997. Subsequent to the
Offering, the operating results of the service business conducted by Kilroy
Services Inc. are reflected in the accompanying financial statements on the
equity method of accounting. All significant intercompany balances and
transactions have been eliminated in the consolidated financial statements.

The combined financial statements of KG reflect a combination of real estate
properties, which were under 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 for 2,652,374 Units upon consummation
of the Offering. KG is considered the precedessor entity to the Company due to
common ownership and management; therefore, its combined financial statements
are presented for comparative purposes.

The accompanying unaudited interim financial statements have been prepared
by the Company's management in accordance with generally accepted accounting
principles and in conjunction with the rules and regulations of the Securities
and Exchange Commission. In the opinion of management, the interim financial
statements presented herein, reflect all adjustments of a normal and recurring
nature which are necessary to fairly state the interim financial statements.
The results of operations for the interim period ended March 31, 1997 are not
necessarily indicative of the results that may be expected for the eleven
months ended December 31, 1997.

The Company intends to qualify as a real estate investment trust ("REIT")
under Section 856 through 860 of the Internal Revenue Code of 1986, as amended
(the "Code")commencing the year ended December 31, 1997. As a REIT, the
Company will not generally be subject to corporate Federal income taxes as
long as it satisfies certain technical requirements of the Code relating to
composition of its income and assets and requirements relating to
distributions of taxable income to stockholders. Prior to formation of the
Company, no provision for Federal income taxes was made in the financial
statements as the income or loss of KG was included in the taxable income of
the individual partners.

Significant Accounting Policies:

Rental Properties--Rental properties are stated at historical cost less
accumulated depreciation, which, in the opinion of the Company's management
does not require a provision for impairment. Net realizable value does not
purport to represent fair market value. Costs incurred for the acquisition,
renovation and betterment of the properties are capitalized. Maintenance and
repairs are charged to expense as incurred.

F-16
<PAGE>

KILROY REALTY CORPORATION CONSOLIDATED
AND KILROY GROUP COMBINED

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

During 1995, KG adopted Statement of Financial Accounting Standards ("SFAS")
No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-
Lived Assets to be Disposed of." Under this standard, if impairment conditions
exist, the Company makes an assessment of the recoverability of the carrying
amounts of individual properties by estimating the future undiscounted cash
flows, excluding interest charges, on a property-by-property basis. If the
carrying amount exceeds the aggregate future cash flows, the Company would
recognize an impairment loss to the extent the carrying amount exceeds the
fair value of the property. Any long-lived assets to be disposed of are to be
valued at estimated fair value less costs to sell. Based on such periodic
assessments, no impairments have been determined and, therefore, no real
estate carrying amounts have been adjusted.

Depreciation and Amortization--The cost of buildings and improvements are
depreciated on the straight-line method over estimated useful lives, as
follows:

Buildings--25 to 40 years.

Tenant improvements--The shorter of lease term or useful lives range
from 5 to 20 years.

Restricted Cash--Restricted cash consists of cash held as collateral to
provide credit enhancement for the mortgage loans payable and cash reserves
for capital expenditures and tenant improvements.

Accrued Cost of Option Buy-out and Tenant Improvements--In September 1996,
KG amended the terms of certain of their lease agreements. Such amendments
included a $500,000 allowance for tenant improvements. In addition, KG agreed
to pay $3,150,000 in consideration for the cancellation of an option to
purchase a 50% equity interest in Kilroy Airport Center at El Segundo which
has been reflected in the statement of operations as of December 31, 1996. In
November 1996, $2,260,000 of the total liability of $3,650,000 was paid by KI
and its stockholders. In January 1997, $100,000 of the amount was paid by KG
and the remaining balance was paid with the proceeds of the Offering.

Deferred Charges--Deferred charges include deferred leasing costs and loan
fees. Leasing costs include leasing commissions that are amortized on the
straight-line basis over the initial lives of the leases, which range from 5
to 10 years. Deferred loan fees are amortized on a straight-line basis over
the terms of the respective loans, which approximates the effective interest
method.

Accrued Property Taxes--As of December 31, 1996 and 1995 $147,000, and
$696,000 of accrued property taxes of the Company and Kilroy Group
respectively, were delinquent. Accrued property taxes are included in accounts
payable and accrued expenses. As of June 30, 1997, all property taxes were
current.

Revenue Recognition and Tenant Receivables--Leases with tenants are
accounted for as operating leases. Minimum annual rentals are recognized on a
straight-line basis over the lease term. Unbilled deferred rent represents the
amount that expected straight-line rental income exceeds rents currently due
under the lease agreement. Total tenant receivables consists of the following
amounts:

Included in tenant rent and reimbursements receivable are additional rentals
based on common area maintenance expenses and certain other expenses that are
accrued in the period in which the related expenses are incurred.

Rents Received in Advance and Tenant Security Deposits--The balances as of
December 31, 1996 and 1995 include a $4,000,000 payment received from a tenant
in connection with the tenant's obligation to remove tenant improvements upon
termination of the lease. Such payment is nonrefundable and will be recognized
as income, net of the costs of removal of improvements, upon termination of
the lease. The related lease expires in 1999, subject to a five-year option to
renew.

Parking--The Kilroy Airport Center at El Segundo includes parking
facilities. KG records as rental income the gross parking receipts. KG
contracts with parking management companies to operate the parking facilities,
and such contract costs are included in property expenses.

Development Services--Development services revenues represent fees earned by
KG for supervision services provided for building development of nonowned
properties. Fees are typically a percentage of total development costs plus
reimbursement for certain expenses. Unreimbursed expenses are recorded as
development expenses and include items such as wages, equipment rental,
supplies, etc.

Sale of Air Rights--In 1995, based on an agreement between KG and the
California Transportation Commission, KG received $4,456,000, net of related
expenses, for granting temporary construction and permanent air right
easements over a portion of its Property for the construction of a freeway on-
ramp. In connection with this transaction, KG accrued $874,000 for the costs
of restoration of the property after construction of the on-ramp.

Property Tax Refunds--Property tax refunds of $2,379,000 were collected in
1995 and relate to appeals filed by KG in 1994 for refunds of property taxes
paid in 1990 through 1994. During the year ended December 31, 1994, such
amount was recorded as a reduction of property taxes, as well as related
interest income of $441,000, which was recorded as other income. Of these
property tax recoveries, approximately $1,500,000 was refunded to tenants of
the related properties and has been recorded as a reduction to tenant
reimbursements income during the year ended December 31, 1994.

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
reporting period. Actual results could differ from those estimates.

4. DEBT

At June 30, 1997, debt consists of an $83,663,000 mortgage loan ( the
"Permanent Loan") secured by certain of the properties and a $12,000,000
mortgage loan (the "SeaTac Loan") secured by an office complex in Seattle,
Washington. The Permanent Loan requires monthly principal and interest
payments based on an interest rate of 8.35%, amortizes over a 25-year period,
but is subject to increases in the effective interest rate beginning in 2005.
The SeaTac Loan requires monthly payments of interest based on a variable rate
of LIBOR plus 3% (8.44% at June 30, 1997) and matures in July 1997 with two
options to extend for six months each. Subsequent to June 30, 1997, the
Company exercised one of the options to extend the maturity for six months and
increased the balance from $12,000,000 to $14,000,000. The interest rate
during the remainder of the term is LIBOR plus 1.5%. As of June 30, 1997 the
loans have a weighted average interest rate of 8.36%.

The fixed rate Permanent Loan of $83,663,000 at June 30, 1997 approximates
its fair value based on terms currently offered to the Company. The carrying
values of the variable rate SeaTac Loan at June 30, 1997, also approximates
its fair value.

Scheduled principal payments for the above mortgage loans at June 30, 1997
are as follows (in thousands):

In May 1997, the Company obtained a $150,000,000 secured revolving credit
facility (the "Credit Facility"). The Credit Facility matures on May 30, 1999,
with an option to extend for one year, and bears interest at the Eurodollar
rate plus 1.5% (8.14% at June 30, 1997) to be used to finance property
acquisitions and development and for general corporate purposes. As of June
30, 1997, the Company had borrowed $92,000,000 under the Credit Facility. On
July 22, 1997, the Company received a commitment to increase the Credit
Facility to $200,000,000. Availability under the Credit Facility is subject
to, among other things, the value of the underlying collateral securing it.

</TABLE>

All of the debt was repaid on January 31, 1997 from the proceeds of the
Offering and new mortgage financing described in Note 1.

(a) In September 1995, a note payable to a bank of $14,000,000 due in
December 1994 and accrued interest payable of $3,867,000 was retired by a cash
payment of $2,600,000. KG recorded an extraordinary gain of $15,267,000 as a
result of this transaction. The remaining notes payable of $16,536,000 were in
default as of December 31, 1995. Past due interest on the remaining notes,
approximately $5,003,000 at December 31, 1995, is included in accrued
interest. See discussion below under (b) regarding settlement of this loan and
accrued interest.

(b) On June 20, 1996, KG obtained a mortgage loan of $21,525,000 from one of
the underwriters of the Offering referred to in Note 1. Such loan bears
interest at 3% above LIBOR. Fees of $2,616,500 were incurred in connection
with obtaining this loan. The proceeds were used to pay: $2,100,000 as
settlement of bank notes with an aggregate principal balance of $16,536,000
and $5,659,000 of unpaid interest, a note payable to an insurance company with
a principal balance of $8,549,000 and a note payable to a finance company with
a principal balance of $4,600,000. The forgiveness of $20,095,000 has been
recorded as an extraordinary gain.

(c) KG was not, as of December 31, 1996, making the required monthly
principal installments of $239,000 on this note and accrued interest of
$2,385,000 was unpaid as of December 31, 1996. The SeaTac Office Center was
pledged as collateral for the note payable. On October 25, 1996, KG and the
insurance company entered into a forbearance agreement which provided KG with
the exclusive right to purchase the note payable for $16,100,000 on or before
January 31, 1997. A portion of the proceeds from the Offering referred to in
Note 1 were used to purchase this note resulting in an extraordinary gain of
$3,204,000 including the write-off of deferred financing fees of $1,283,000 in
1997.

In 1994, two notes payable to insurance companies, with an aggregate unpaid
balance of $6,782,000 were paid after forgiveness of $1,847,000 of principal
by the lenders, which has been recorded as an extraordinary gain.

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

The notes payable were secured by deeds of trust on all KG's properties and
the assignment of certain rents and leases associated with the related
Properties. The notes were generally due in monthly installments of principal
and interest or interest only. As of December 31, 1996, approximately $37.2
million of notes payable were guaranteed by certain members of KG.

5. FUTURE MINIMUM RENT

The Company has operating leases with tenants that expire at various dates
through 2006 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 as well as sales volume of certain retail space
within the office buildings. Future minimum rent under operating leases,
excluding tenant reimbursements of certain costs, as of June 30, 1997 and
December 31, 1996, are summarized as follows (in thousands):

</TABLE>

The majority of KG's 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 and industries in which the tenants operate.

Rental income from one tenant, Hughes Electronics Corporation's Space &
Communications Company ("Hughes"), was $4,498,000, $10,783,000, $10,817,000
and $11,395,000 for the five months ended June 30, 1997 and the years ended
December 31, 1996, 1995 and 1994, respectively. Future minimum rents from this
tenant are $74,098,000 at December 31, 1996.

In September 1996, KG and Hughes amended the terms of certain of their lease
agreements. Such amendments included the extension of one lease through
October 31, 2001 and a $500,000 allowance for tenant improvements. In
addition, KG agreed to pay Hughes $3,150,000 in consideration for the
cancellation of an option to purchase a 50% equity interest in Kilroy Airport
Center at El Segundo which has been reflected in the statement of operations
as of December 31, 1996. In November 1996, $2,260,000 of the total liability
of $3,650,000 was paid by KI and its stockholders. The remaining balance is
payable in monthly installments of $100,000 commencing in January 1997.

6. STOCK OPTIONS

The Company has established a stock option and incentive plan for the
purpose of attracting and retaining qualified executives and to reward them
for superior performance in achieving the Company's business goals and
enhancing stockholder value. As of July 31, 1997, 1,155,000 of the Company's
authorized shares have been granted to directors, officers and employees and
an additional 245,000 have been reserved for issuance under

F-21

such plan. The term of each option is ten years from the date of grant. Each
option vests 33 1/3% per year over three years beginning on the first
anniversary date of the grant and is exercisable at a price per share equal to
the fair market value on the date of grant.

7. COMMITMENTS AND CONTINGENCIES

Operating Leases--KG has a noncancelable ground lease obligation on Kilroy
Airport Center Long Beach with an initial lease period expiring on July 31,
2035, classified as an operating lease. Further, KG has noncancelable ground
lease obligations on the SeaTac Office Center expiring on December 31, 2032
with an option to extend the leases for an additional 30 years and on one of
the properties purchased in connection with the Offering which expires in
2035. Except with respect to one of the ground leases at the SeaTac Office
Center, rentals are subject to adjustments every five years based on changes
in the Consumer Price Index. The minimum commitment under these leases as of
June 30, 1997 and December 31, 1996 are as follows (in thousands):

Litigation--KG is subject to various legal proceedings and claims that arise
in the ordinary course of business. These matters are generally covered by
insurance. While the resolution of these matters cannot be predicted with
certainty, management believes that the final outcome of such matters will not
have a material adverse effect on the financial statements of KG.

8. RELATED-PARTY TRANSACTIONS

KI provides management, legal, accounting and general administrative
services pursuant to agreements that provide for management fees based upon a
percentage of gross revenues from the Properties and reimbursement of other
costs incurred by KI in connection with providing the aforementioned services.
Kilroy Company ("KC"), an affiliated entity, provides marketing and leasing
services. Charges by KC include leasing commissions paid to employees and
outside leasing brokers as well as fees to cover its general administrative
costs. Management fees are expensed as incurred and are included in property
expenses. Leasing fees are capitalized and amortized over the life of the
related leases. In the opinion of KG management, the fees paid to KI and KC
for management and leasing services are comparable to the rates which KG would
have paid an independent company to provide similar services. In addition, KI
is a tenant at the Kilroy Airport Center at El Segundo and Kilroy Airport
Center Long Beach, under month-to-month basis leases. Charges for services
provided by KI and KC and rental income from KI are summarized as follows:

Management fees in 1995 include a fourth quarter charge of $321,000 relating
to management time incurred for the renegotiation of loans.

9. FAIR VALUE DISCLOSURES OF FINANCIAL INSTRUMENTS

The following disclosure of estimated fair value was determined by KG using
available market information and appropriate valuation methodologies. However,
considerable judgment is necessary to interpret market data and develop the
related estimates of fair value. Accordingly, the estimates presented herein
are not necessarily indicative of the amounts that could be realized upon
disposition of the financial instruments. The use of different market
assumptions and/or estimation methodologies may have a material effect on the
estimated fair value amounts. Receivables, accounts payable and other
liabilities are carried at amounts that reasonably approximate their fair
value.

The fixed rate mortgage notes payable totaling $145,518,000 and $162,510,000
as of December 31, 1996 and 1995 have fair values of $151,472,000 and
$165,300,000, respectively (excluding prepayment penalties), as estimated
based upon interest rates available for the issuance of debt with similar
terms and remaining maturities. The carrying values of floating rate mortgages
totaling $77,779 and $71,347,000 at December 31, 1996 and 1995, respectively,
reasonably approximate their fair values.

The fair value estimates presented herein are based on information available
to KG management as of December 31, 1996 and 1995. Although KG management is
not aware of any factors that would significantly affect the estimated fair
value amounts, such amounts have not been comprehensively revalued for
purposes of these financial statements since that date, and current estimates
of fair value may differ significantly from the amounts presented herein.

10. UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION

The accompanying unaudited pro forma information for the six months ended
June 30, 1997 and 1996 are presented as if the Formation Transactions
described in Note 1 to the financial statements had occurred on January 1,
1996. Such pro forma information is based upon the historical consolidated
financial statements of the Company and the KG and should be read in
conjunction with the consolidated and combined financial statements and the
notes thereto.

This unaudited pro forma condensed consolidated information does not purport
to represent what the actual results of operations of the Company would have
been assuming such Formation Transactions had been completed as set forth
above, nor do they purport to predict the results of operations for future
periods.

INDEPENDENT AUDITORS' REPORT

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

We have audited the accompanying combined historical summary of certain
revenues and certain expenses (defined as operating revenues less direct
operating expenses) of the Acquisition Properties for the year ended
December 31, 1996. This historical summary is the responsibility of the
Acquisition Properties' management. Our responsibility is to express an
opinion on this combined historical summary based on our audit.

We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the combined historical summary of
certain revenues and certain expenses is free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the combined historical summary of certain revenues and certain
expenses. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
presentation of the combined historical summary of certain revenues and
certain expenses. We believe our audit provides a reasonable basis for our
opinion.

The accompanying combined historical summary of certain revenues and certain
expenses was prepared for the purpose of complying with the rules and
regulations of the Securities and Exchange Commission for inclusion in the
Form S-11 Registration Statement of Kilroy Realty Corporation. Material
amounts, described in Note 1 to the historical summary of certain revenues and
certain expenses, that would not be comparable to those resulting from the
proposed future operation of the Acquisition Properties are excluded, and the
summary is not intended to be a complete presentation of the revenues and
expenses of these properties.

In our opinion, such historical summary of certain revenues and certain
expenses presents fairly, in all material respects, the combined summary of
certain revenues and certain expenses, as defined in Note 1, of the
Acquisition Properties for the year ended December 31, 1996 in conformity with
generally accepted accounting principles.

INDEPENDENT AUDITORS' REPORT

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

We have audited the accompanying combined historical summary of certain
revenues and certain expenses (defined as operating revenues less direct
operating expenses) of the Post IPO Acquisitions Through June 30, 1997 (as
described in Note 1) (the "Properties") for the year ended December 31, 1996.
This combined historical summary is the responsibility of the respective
Properties' management. Our responsibility is to express an opinion on this
combined historical summary of certain revenue and certain expenses based on
our audit.

We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform our audit to
obtain reasonable assurance about whether the combined historical summary of
certain revenues and certain expenses is free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the combined historical summary of certain revenues and certain
expenses. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
presentation of the combined historical summary of certain revenues and
certain expenses. We believe that our audit provides a reasonable basis for
our opinion.

The accompanying combined historical summary of certain revenues and certain
expenses was prepared for the purpose of complying with the rules and
regulations of the Securities and Exchange Commission for inclusion in the
Registration Statement on Form S-11 of Kilroy Realty Corporation. Material
amounts, described in Note 1 to the combined historical summary of certain
revenues and certain expenses, that would not be comparable to those resulting
from the proposed future operation of the Properties are excluded, and the
historical summary is not intended to be a complete presentation of the
revenues and expenses of these properties.

In our opinion, such combined historical summary of certain revenues and
certain expenses presents fairly, in all material respects, the combined
certain revenues and certain expenses, as defined above, of the Properties for
the year ended December 31, 1996 in conformity with generally accepted
accounting principles.

Our audit was conducted for the purpose of forming an opinion on the basic
combined historical summary of certain revenues and certain expenses taken as
a whole. The additional combining information is presented for the purpose of
additional analysis of the basic combined historical summary of certain
revenues and certain expenses rather than to present the results of operations
of the individual properties and is not a required part of the basic combined
historical summary of certain revenues and certain expenses. This additional
combining information is the responsibility of the respective Properties'
management. Such information has been subjected to auditing procedures applied
in our audit of the basic combined historical summary of certain revenues and
certain expenses for the year ended December 31, 1996 and, in our opinion, is
fairly stated in all material aspects when considered in relation to the basic
combined historical summary of certain revenues and expenses taken as a whole.
