KILROY REALTY CORPORATION
Common Stock

[LOGO OF KILROY REALTY CORPORATION]
- -------------------------------------------------------------------------------
Kilroy Realty Corporation (the "Company") has been formed to succeed to the
business of Kilroy Industries and its affiliates consisting principally of a
portfolio of Class A suburban office and industrial buildings in prime
locations, primarily in Southern California, and the affiliated real estate
ownership, acquisition, development, leasing and management businesses which
were established in Southern California in 1947. Upon the consummation of this
offering (the "Offering") and a series of related transactions (the "Formation
Transactions"), the Company will own 14 suburban office buildings (the "Office
Properties"), 11 of which are located in Southern California, and 12
industrial properties (the "Industrial Properties"), 11 of which are located
in Southern California. The Company will operate as a self-administered and
self-managed real estate investment trust (a "REIT"). The Company intends to
make regular quarterly distributions to its stockholders beginning with a
distribution for the period ending March 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 and will
represent approximately 82.0% of all shares of Common Stock (or interests
exchangeable therefor) outstanding after consummation of the Offering. Upon
consummation of the Offering, the Company's officers and directors (and
certain of their affiliates) will own in the aggregate 18.1% of the Common
Stock or interests exchangeable therefor. See "Principal Stockholders." 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.

Prior to the Offering, there has been no public market for the Common Stock of
the Company. The shares of Common Stock offered hereby have been approved for
listing on the New York Stock Exchange (the "NYSE") under the symbol "KRC."
See "Glossary" beginning on page 164 for definitions of certain terms used in
this Prospectus.

See "Risk Factors" on pages 20 to 35 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
Formation Transactions, consummation of the Offering and 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 the Services
Company, which could result in decisions that do not reflect the Company's
interest.
. The valuation of the Company's properties was not based on third-party
appraisals, and the consideration to be paid by the Company for the
properties may exceed their aggregate fair market value, thereby increasing
the risk that the aggregate market value of the Common Stock may exceed the
Company's total assets.
. 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, industrial and retail 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 Electronic
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 Company's Common Stock.

reference to the Company's ownership in the Operating Partnership includes the
Company's interests in the subsidiaries of the Operating Partnership.
Additional capitalized terms shall have the meanings set forth in the Glossary

THE COMPANY

The Company has been formed to succeed to the business of the Kilroy Group,
consisting principally of a portfolio of Class A suburban office and industrial
buildings in prime locations, primarily in Southern California, and the Kilroy
Group's real estate ownership, acquisition, development, leasing and management
businesses which were established in Southern California in 1947. Upon the
consummation of the Offering and the Formation Transactions, the Company
(through the Operating Partnership) will own 14 Office Properties encompassing
an aggregate of approximately 2.0 million rentable square feet and 12
Industrial Properties encompassing an aggregate of approximately 1.3 million
rentable square feet. Eleven of the 14 Office Properties and 11 of the 12
Industrial Properties are located in prime Southern California suburban
submarkets (including a complex of three Office Properties located in El
Segundo, adjacent to the Los Angeles International Airport, presently the
nation's second largest air-cargo port, and a complex of five Office Properties
located adjacent to the Long Beach Municipal Airport). The Company also will
own three Office Properties located adjacent to the Seattle-Tacoma
International Airport in the State of Washington and one Industrial Property
located in Phoenix, Arizona. The Office Properties, Industrial Properties and
the related assets owned by the Partnerships contributed to the Company by the
Continuing Investors in connection with the Formation Transactions are
collectively referred to herein as the "Properties." As of September 30, 1996,
the Office Properties were approximately 79.8% leased to 130 tenants and the
Industrial Properties were approximately 93.7% leased to 20 tenants. The
average age of the Office Properties and the Industrial Properties is
approximately 12 years and 24 years, respectively. The Company developed and
leased all but two of the 14 Office Properties and all but five of the 12
Industrial Properties, and, upon consummation of the Offering and acquisition
of the Acquisition Properties, will manage all of the Properties.

1
<PAGE>

The Company was founded in 1947 by John B. Kilroy, Sr., a nationally
prominent member of the real estate community, and is led by John B. Kilroy,
Jr., the Company's Chief Executive Officer and President. The Company's
executive officers have been with the Company for an average of approximately
13 years. The Company presently has 47 employees, 34 of whom are located at the
Company's headquarters at Kilroy Airport Center at El Segundo, California. Upon
consummation of the Offering, the Company's officers and directors (and certain
of their affiliates) will own in the aggregate 18.1% of the Company's Common
Stock (or interests exchangeable therefor).

The Company's strategy has been to own, develop, acquire, lease and manage
Class A properties in select locations in key suburban submarkets, primarily in
Southern California, that the Company believes have strategic advantages
compared to neighboring submarkets. Existing locations 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, airports and the expanded Southern California
light-rail system; (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--Office Properties" and "--Industrial Properties."

The Company's major tenants include, among others, Hughes Electronic
Corporation's Space & Communications Company and related companies ("Hughes
Space & Communications"), a tenant since 1984, which is engaged in high-
technology commercial activities including satellite development and related
applications such as DirecTV, as well as Mattel, Inc., Northwest Airlines,
Inc., Olympus America, Inc. and Furon Co., Inc. As of December 31, 1995, the
Company's ten largest office tenants and ten largest industrial tenants (based
upon annual base rents as of December 31, 1995) had leased space from the
Company for an average of 5.3 years. The Company's strong relationships with
its tenants is further evidenced by its average tenant retention rate (based
upon rentable square feet) for the period beginning January 1, 1994 and ending
September 30, 1996, which was 71.7% for the Properties located in the Southern
California Area. The Company's extensive experience and long-term presence in
Southern California have enabled it to form key alliances and working
relationships with large corporate tenants, municipalities and landowners that
have led to a variety of development projects and provide a continuing source
of development and acquisition opportunities with institutional sellers. As a
result of its experience and relationships, the Company currently has exclusive
rights to develop approximately 24 acres of developable land (net of the
acreage required for streets) at Kilroy Airport Center Long Beach (the
"Development Properties"). These properties are presently entitled for over
900,000 rentable square feet of office, industrial and retail space. See
"Business and Properties--Development, Leasing and Management Activities."

The Company believes, based on independent economic surveys, that the
Southern California office and industrial real estate market is recovering
after experiencing a downturn over the last several years. Vacancy rates in the
Class A office space market in the greater Southern California area, including
the counties of Los Angeles, Orange, Riverside, San Bernardino and Ventura (the
"Southern California Area"), have decreased from a high in 1991 and 1992 of
nearly 20.0% to a level at the end of 1996 of under 17.0%. Vacancy rates in the
industrial space market in the Southern California Area also are decreasing
from a high of nearly 14.0% in 1992 to 7.6% at the end of 1996. In addition,
the Company has on average achieved increases in rental rates since 1994 in the
Office Properties it has managed. See "--The Company's Southern California
Submarkets" and "Business and Properties--The Company's Southern California
Submarkets." Management believes that the on-going 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. See "--Growth
Strategies."

2
<PAGE>

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 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 will be one of a limited number of REITs focusing on office
and industrial properties and that it will be the only REIT with a 50-year
operating history concentrating primarily on suburban Southern California
office and industrial properties. In the 12 months following the consummation
of the Offering, the Company expects sources of potential growth in cash
available for distribution per share from the amount set forth under the
caption "Distribution Policy" through: (i) the further leasing of its available
space, currently approximately 400,000 rentable square feet; (ii) the renewal
of leases for approximately 60,000 rentable square feet which expire during
such period; and (iii) the acquisition of strategic properties with Units
and/or with available cash and borrowings under a $100.0 million revolving
credit facility (the "Credit Facility") which the Company expects to enter into
shortly after the Offering and its approximately $76 million of working capital
cash reserves upon consummation of the Offering. In the second 12-month period
following consummation of the Offering, the Company expects sources of
potential growth in cash flow per share from: (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 planned development activities. In addition, the Company
presently plans to expand one or more of its Industrial Properties during the
next two years, subject to substantial pre-leasing. There can be no assurance,
however, that the Company will achieve any growth in cash available for
distribution per share, 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."

The Company will be fully integrated in that it will perform substantially
all leasing, management and tenant improvements on an "in-house" basis and will
be self-administered and self-managed. The Company expects to qualify as a REIT
for federal income tax purposes beginning with its taxable year ending December
31, 1997. See "Federal Income Tax Consequences--Taxation of the Company."

RISK FACTORS

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, in connection
with an investment in the shares of Common Stock offered hereby. Such risks
include, among others:

. conflicts of interest, particularly with the Continuing Investors
(including John B. Kilroy, Sr. and John B. Kilroy, Jr.) in connection
with the (i) Formation Transactions, (ii) operation of the Company's
ongoing businesses, including conflicts associated with the tax
consequences to Continuing Investors of sales or refinancings of any of
the Properties, which, together with certain provisions of the Operating
Partnership agreement, may influence the Company's decision to sell or
refinance, or to prepay debt secured by, certain properties, (iii)
potential election by the Company to exercise its option to purchase any
of the properties owned or controlled by one or more of the Continuing
Investors which the Company has the option to acquire (the "Excluded
Properties") and (iv) 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 the Company's ability to withdraw as general partner of
the Operating Partnership, transfer or assign its interest in the
Operating Partnership without the consent of at least 60% of the Units
(including Units held by the Company which will represent 82.6% of all
Units outstanding upon consummation of the Offering) and without meeting
certain criteria with respect to the consideration to be received by the
Continuing Investors, or to dissolve the Operating Partnership or sell
the Office

3
<PAGE>

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 the
Company), 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 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;

. the valuation of the Properties was not based on third-party appraisals
and there have not been arm's-length negotiations with respect to such
values. The consideration to be paid by the Company for the Properties
may exceed their aggregate fair market value;

. 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 22 of its 26 Properties in Southern
California, creating a dependence on demand for office, industrial and
retail 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 25.3% of the Company's total base rental revenues for the
year ending December 31, 1995 (giving pro forma effect to a recent
extension of a lease with Hughes Space & Communications with respect to
two of the Office Properties located at Kilroy Airport Center at El
Segundo), 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
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
Continuing Investors who are directors and executive officers of the
Company, and the ability of 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;

<PAGE>

. potential antitakeover 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
Operating Partnership 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 expected levels,
materially adversely affecting the Company's ability to make the
expected annual distributions of $1.55 per share during the 12-month
period following consummation of the Offering (which represents
approximately 90.7% of the estimated cash available for distribution for
such period) or to sustain such 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;

. immediate and substantial dilution of $12.71 per share in the net
tangible book value per share of the shares of Common Stock purchased by
new investors in the Offering;

. no prior public market for the shares of Common Stock, including the
risk that an active trading market might not develop, or if developed
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 future
development; and

. the possible issuance of additional shares of Common Stock, including
2,652,374 shares of Common Stock issuable upon exchange of the Units
outstanding upon consummation of the Offering, 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

The Company was formed in September 1996 and the Operating Partnership was
formed in October 1996. The Services Company will be formed prior to
consummation of the Offering. Prior to or simultaneous with the consummation of
the Offering, the Company, the Operating Partnership, the Services Company and
the Continuing Investors will engage in certain transactions (the "Formation
Transactions"), designed to enable the Company to continue and expand the real
estate operations of the Continuing Investors, to facilitate the Offering, 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 the existing owners of the Properties. The Formation
Transactions are as follows:

. Pursuant to an omnibus option agreement (the "Omnibus Agreement"), the
Operating Partnership may require the contribution to the Operating
Partnership of all of the Continuing Investors' interests in the
Properties (other than the Acquisition Properties), the assets used to
conduct the leasing, management and development activities (principally
office equipment), the contract rights in connection with

5
<PAGE>

development opportunities at Kilroy Airport Center Long Beach, and the
rights with respect to the purchase of each of the Acquisition
Properties, in exchange for Units representing limited partnership
interests in the Operating Partnership. The book value to the Continuing
Investors of the assets to be contributed to the Operating Partnership
is a negative $113.2 million and the value of the Units representing
limited partnership interests in the Operating Partnership to be
received by the Continuing Investors is $61.0 million, assuming a Unit
value equal to the initial public offering price of $23.00 per share.
The right to acquire the Properties and the other assets described above
in exchange for Units is conditioned upon the consummation of the
Offering. Pursuant to the terms of the Omnibus Agreement, the Operating
Partnership has the right to acquire the Properties and other assets
from the Continuing Investors in exchange for Units through December 31,
1998, the date the Omnibus Agreement terminates. Following the
consummation of the Offering and the Formation Transactions, the Units
received by the Continuing Investors will constitute in the aggregate an
approximately 17.4% limited partnership interest in the Operating
Partnership.

. John B. Kilroy, Sr. and John B. Kilroy, Jr. will acquire 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 will acquire all of the non-voting preferred
stock of the Services Company (representing 95.0% of its economic
value).

. The Company will sell shares of Common Stock in the Offering, issue
restricted shares of Common Stock to Richard E. Moran Jr., Executive
Vice President, Chief Financial Officer and Secretary of the Company
(but not a Continuing Investor) and contribute the net proceeds from the
Offering and the issuance of such restricted stock (approximately $262.9
million in the aggregate) to the Operating Partnership in exchange for
an 82.6% general partner interest in the Operating Partnership.

. The Operating Partnership will borrow approximately $84.0 million in
principal amount of long-term financing and $12.0 million in principal
amount of short-term debt pursuant to the Mortgage Loans.

. The Company, through the Operating Partnership, will apply the aggregate
of the net Offering proceeds and the Mortgage Loans toward the repayment
of existing mortgage indebtedness on certain of the Properties, the
purchase of the Acquisition Properties and the payment of its expenses
from the Offering and the Financing. See "Use of Proceeds."

. Forty-seven of the current 69 employees of KI will become 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 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 Continuing
Investors and 43 other operating and administrative employees. See
"Management."

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

. Concurrent with the consummation of the Offering, the Company also will
enter into option agreements (together, the "Option Agreements") with
partnerships controlled by John B. Kilroy, Sr. and John B. Kilroy, Jr.
granting to the Operating Partnership the exclusive right to acquire (i)
approximately 18

6
<PAGE>

undeveloped acres located at Calabasas Park Centre for cash and (ii) the
Office Property located at North Sepulveda Boulevard, El Segundo for
cash (or for Units after the first anniversary of the Offering at the
election of the seller), and in each case pursuant to the other terms of
the respective Option Agreement. See "Business and Properties--Excluded
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.

The Continuing Investors are comprised of (i) seven individuals, John B.
Kilroy, Sr., his five children, John B. Kilroy, Jr., Patrice Bouzaid, Susan
Hahn, Anne McCahon and Dana Pantuso, and Marshall L. McDaniel, a long-time
employee of KI, all of whom are "accredited investors" as defined in
Regulation D ("Regulation D") under the Securities Act, and (ii) corporations,
partnerships and trusts owned, directly or indirectly, solely by such
individuals, all of which are also "accredited investors." See "Note 1.
Organization and Basis of Presentation" to the historical financial statements
of the Kilroy Group. In addition, John B. Kilroy, Sr. is the Company's
Chairman of the Board of Directors and John B. Kilroy, Jr. is President and
Chief Executive Officer and a director of the Company. Consent on behalf of
the Continuing Investors to the Formation Transactions was received on or
before November 3, 1996 pursuant to a private solicitation thereof in
compliance with Regulation D.

REASONS FOR THE REORGANIZATION OF THE COMPANY

The Company believes that the benefits of the Formation Transactions
outweigh the detriments to the Company. The benefits of the Company's REIT
status and structure, as opposed to the status and structure of the
Partnerships, include greater access to capital for refinancing and growth,
allowing stockholders to participate in real estate growth through one
business enterprise, diversification of risk and reward not available in
single asset entities, reduction in indebtedness encumbering the Properties,
greater liquidity than interests in partnerships owning individual properties,
allowing stockholders to benefit potentially from the current public market
valuation of REITs and deferral of tax liabilities to the Continuing Investors
upon contribution of the Properties.

The detriments of the Company's REIT status and structure as opposed to the
status and structure of the Partnerships include the fact that management will
be subject to conflicts of interest in the operation of the Operating
Partnership and the limited partners of the Operating Partnership will have
certain approval rights with respect to certain transactions, including (i)
the right of partners holding in the aggregate at least 60% of all interests
in the Operating Partnership to withhold consent to the withdrawal of the
general partner, or the transfer or assignment of the general partner's
interest in the Operating Partnership (see "Partnership Agreement of the
Operating Partnership--Transferability of Interests") and (ii) if limited
partners own at least 5% of the outstanding Units (including Units owned by
the Company), the right of limited partners holding in the aggregate more than
50% of all Units representing limited partnership interests in the Operating
Partnership to withhold consent to (a) the dissolution of the Operating
Partnership (other than pursuant to a merger or sale of substantially all of
the Company's assets) or (b) prior to the seventh anniversary of the
consummation of the Offering, to sell the Office Property located at 2260 E.
Imperial Highway at Kilroy Airport Center at El Segundo (see "Partnership
Agreement of the Operating Partnership--Certain Limited Partner Approval
Rights"). In addition, the Continuing Investors will have influence over
certain transactions, including with respect to the Company's acquisition,
management and leasing activities, asset sales, dispositions and refinancings
of properties and its distribution policy. Other detriments of the Company's
REIT status include a potential lower overall rate of return for an investor
who exchanges an interest in a single asset for a smaller interest in a group
of assets, lower potential of distributions from asset sales, no assurance
that the public market valuation of the Company will reflect private real
estate values, the aggregate cost to the Company of the Offering (estimated at
approximately $24.6 million, including underwriting discounts and commissions)
and the incremental costs of operating a public company. See also "Risk
Factors."

The following diagram illustrates the structure of the Company, the Operating
Partnership and the Services Company after the consummation of the Offering and
the Formation Transactions:

Kilroy Realty Corporation

preferred stock owned by
the Operating Partnership(/2/)
100% voting common stock
owned by John B. Kilroy, Sr.
and John B. Kilroy, Jr.(/3/)

- --------
(1) 12,500,000 shares of Common Stock, representing 99.2% of the outstanding
shares of Common Stock after the Offering, will be owned by public
stockholders and 100,000 restricted shares of Common Stock, representing
0.8% of the outstanding shares of Common Stock, will be owned by Richard E.
Moran Jr., Executive Vice President, Chief Financial Officer and Secretary
of the Company (but not a Continuing Investor). If all Units of the
Operating Partnership were exchanged for Common Stock, the Company would be
owned approximately 82.0% by public stockholders, 0.6% by Mr. Moran and
17.4% by the Continuing Investors. Beginning on the second anniversary of
the consummation of the Offering, each Unit will be redeemable 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
antidilution adjustments and exceptions; 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 Company's Articles
of Incorporation or as otherwise permitted by the Board of Directors. See
"Partnership Agreement of Operating Partnership--Redemption/Exchange
Rights." Under certain circumstances, 50% of the Units received by John B.
Kilroy, Sr., John B. Kilroy, Jr. and Kilroy Industries may be redeemed
prior to the second anniversary of the consummation of the Offering in
connection with the obligation of certain of the Continuing Investors to
indemnify the Company in connection with the Formation Transactions. See
"Formation and Structure of the Company--Allocation of Consideration in the
Formation Transactions." Executive officers, directors and other employees
of the Company will have options to acquire approximately 900,000 shares of
Common Stock which could reduce the percentage owned by public stockholders
to approximately 77.4% (assuming exchange of all outstanding Units and the
exercise of all outstanding options).

(2) Represents 95.0% of the economic interest in the Services Company.

(3) Represents 5.0% of the economic interest in the Services Company.

The Company presently anticipates that one of the Mortgage Loans (see "--The
Financing") will be incurred by a limited partnership which is wholly-owned by
the Company and the Operating Partnership and which will be structured to be a
"bankruptcy remote" financing vehicle. The Properties pledged as collateral for
such Mortgage Loan will be transferred to such limited partnership.

<PAGE>

BENEFITS TO THE CONTINUING INVESTORS

The principals of KI proposed the Formation Transactions to the Continuing
Investors because they believe that the benefits of the organization of the
Company for the Continuing Investors outweigh the detriments to them. Benefits
to the Continuing Investors include:

. improved liquidity of their interests in the Properties and increased
diversification of their investment;

. repayment of indebtedness in the aggregate net amount of approximately
$229.5 million resulting from the refinancing of existing mortgage
indebtedness, of which approximately $37.2 million is guaranteed by John
B. Kilroy, Sr., including $8.7 million which also is 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

. the deferral of certain tax consequences that would arise from a sale,
or in certain circumstances a contribution, of such interests and assets
to the Company or to a third party.

DETERMINATION AND VALUATION OF OWNERSHIP INTERESTS

The Company's percentage interest in the Operating Partnership was determined
based upon the percentage of estimated cash available for distribution required
to pay estimated cash distributions resulting in an annual distribution rate
equal to 6.74% of the initial public offering price of the Common Stock of
$23.00. The ownership interest in the Operating Partnership allocated to the
Company is equal to this percentage of estimated cash available for
distribution, and the remaining interest in the Operating Partnership will be
allocated to the Continuing Investors receiving Units in the Formation
Transactions. The parameters and assumptions used in deriving the estimated
cash available for distribution are described under the caption "Distribution
Policy."

In connection with the Offering, the Company did not obtain appraisals with
respect to the market value of any of the Properties or other assets that the
Company will own immediately after consummation of the Offering and the
Formation Transactions or an opinion as to the fairness of the allocation of
shares to the purchasers in the Offering. The initial public offering price has
been determined based upon the estimated cash available for distribution and
the factors discussed under the caption "Underwriting," rather than a property
by property valuation based on historical cost or current market value. This
methodology has been used because management believes it is appropriate to
value the Company as an ongoing business rather than with a view to values that
could be obtained from a liquidation of the Company or of individual properties
owned by them. See "Underwriting."

FORMATION OF KILROY SERVICES, INC.

Prior to consummation of the Offering, Kilroy Services, Inc. (the "Services
Company") will be formed under the laws of the State of Maryland to succeed to
the development activities of the Kilroy Group and to perform development
activities for the Company and third parties. John B. Kilroy, Sr. and John B.
Kilroy, Jr. together will own 100% of the voting common stock of the Services
Company, representing 5.0% of its economic value. The Operating Partnership
will own 100% 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 anticipates receiving 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
will not be able to elect the Services Company's officers or directors and,
consequently, may not have

9
<PAGE>

the ability to influence the operations of the Services Company. 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."

GROWTH STRATEGIES

The Company's objectives are to maximize growth in cash flow per share 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 flow per share: (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 as vacancy rates in the
Company's submarkets generally continue to decline; (iv) by developing
properties for the benefit of the Company where such development will result in
a favorable risk-adjusted return on investment; and (v) by expanding Properties
within the Company's existing industrial portfolio. The Company's ability to
achieve its growth strategy will be aided by its working capital cash reserves
of approximately $76 million upon consummation of the Offering and the proposed
Credit Facility.

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 the
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 distressed sellers and inadvertent owners (through foreclosure or
otherwise) of office and industrial properties in the Company's markets, as
well as the Company's ability to acquire properties with Units (thereby
deferring the seller's taxable gain), all of which create enhanced acquisition
opportunities; (iii) the quality and location of the Properties; and (iv) the
limited availability to competitors of capital for financing development,
acquisitions or capital improvements. Management believes that the Company is
well positioned to exploit existing opportunities because of its extensive
experience in its submarkets and its nearly 50-year presence in the Southern
California market, its seasoned management team and its proven ability to
develop, lease and efficiently manage office and industrial properties. In
addition, the Company believes that public ownership and its 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 will focus on enhancing growth in cash flow
per share by: (i) maximizing cash flow from existing 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.

and Orange Counties, respectively. As of September 30, 1996, (i) the Office
Properties contained approximately 2.0 million rentable square feet and were
approximately 79.8% leased, and (ii) the Industrial Properties contained
approximately 1.3 million rentable square feet and were approximately 93.7%
leased. In addition, the number of individual lease transactions since 1992,
including the results for the nine-month period ended September 30, 1996,
averaged over 33 per year. See "Business and Properties--General," "--
Properties," "--Occupancy and Rental Information" and "--The Company's Southern
California Submarkets."

Approximately 1.0 million aggregate rentable square feet in the Properties
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, approximately 66.5%
of the Company's net 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
December 31, 1995 approximately 36.7% of the Company's total base rent
(representing approximately 23.7% of the aggregate net rentable square feet of
the Properties) was attributable to leases with Consumer Price Index increases
and approximately 28.1% of the Company's total base rent (representing
approximately 30.5% of the aggregate net 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 will seek to increase its cash flow per
share by acquiring additional quality office and industrial properties,
including properties that may: (i) 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 extensive experience, 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."

The Company has entered into an agreement to acquire the two office
properties that comprise Phase I of Kilroy Airport Center Long Beach. Kilroy
Airport Center Long Beach Phase I was developed by the Company in 1987 and has
been leased and managed by the Company since its inception. In addition, the
Company has entered into an agreement to purchase an office property located in
Thousand Oaks, California. The Company also has entered into an agreement to
acquire a three building office and industrial complex located in Anaheim,
California. In addition, KI, on behalf of the Operating Partnership, has
acquired a multi-tenant industrial property located in Garden Grove,
California. The acquisition of these properties (the "Acquisition Properties")
by the Company is expected to occur concurrently with the consummation of the
Offering and, accordingly, the Acquisition Properties are included in the
discussion of the Properties included throughout this Prospectus. There can be
no assurance, however, that the Company will be able to complete any property
acquisitions, including the acquisition of the Acquisition Properties,
successfully develop any land acquired or improve the operating results of any
developed properties that are acquired. See "Business and Properties--
Acquisition Properties."

Development Strategies. The Company's interests in the Development Properties
provide it with significant growth opportunities.

11
<PAGE>

The Company is the master ground lessee of, and has sole development rights
in, Kilroy Airport Center Long Beach, a planned four-phase, approximately 53-
acre property entitled for office, research and development,
light industrial and other commercial projects at which the Company will own,
upon consummation of the Offering, all five existing Office Properties and
manages all ongoing leasing and development activities. The Company developed
Phases I and II in 1987 and 1989/1990, respectively, encompassing an aggregate
of approximately 620,000 rentable square feet of office space. The Company
controls development of the Phase III and IV parcels while receiving rental
revenue in connection with such parcels under current leases expiring in July
2009 and September 1998, respectively, in amounts sufficient to cover a
substantial portion of the predevelopment carrying costs. Phases III and IV
presently are planned to be developed on the projects' approximately 24
undeveloped acres and are entitled for an aggregate of approximately
900,000 rentable square feet. The Company is currently in discussions with
several prospective tenants for office space presently planned to be included
in Kilroy Long Beach Phase III. Development of each of Phases III and IV is
subject to substantial predevelopment leasing activity and, therefore, the
timing for the commencement of development of Phases III and IV is uncertain.
No assurance can be given that the Company will commence such development when
planned, or that, if commenced, 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 Long Beach."

In addition, certain of the Industrial Properties can support additional
development, and the Company presently is planning to develop in the next two
years, subject to substantial pre-leasing, approximately 105,000 rentable
square feet of such additional space.

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 Company's Board of Directors. The Company presently intends
to limit 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. Upon
completion of the transactions outlined under the caption "Formation and
Structure of the Company," total debt will constitute approximately 21.5% of
the total market capitalization of the Company. In addition, upon consummation
of the Offering, the Company will have working capital cash reserves of
approximately $76 million. The Company anticipates that upon consummation of
the Offering all but approximately $12.0 million of its permanent indebtedness
will bear interest at fixed rates. The Company intends to utilize one or more
sources of capital for future acquisitions, including development and capital
improvements, which may include undistributed cash flow, borrowings under the
proposed Credit Facility, the Company's approximately $76 million of working
capital cash reserves 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 "--Growth Strategies," "The Company--Growth Strategies" and
"Business and Properties--Development, Leasing and Management Activities."

THE OFFICE AND INDUSTRIAL PROPERTIES

The following table sets forth certain information relating to each of the
Properties as of December 31, 1995, unless indicated otherwise. This table
gives pro forma effect to a recent extension of one of the leases with Hughes
Space & Communications with respect to two of the Office Properties located at
Kilroy Airport Center at El Segundo as if such lease renewal had occurred on
January 1, 1995. After completion of the Formation Transactions, the Company
(through the Operating Partnership) will own a 100% interest in all of the
Office and Industrial Properties other than the five Office Properties located
at Kilroy Airport Center Long Beach and the three Office Properties located at
the SeaTac Office Center, each of which are held subject to ground leases
expiring in 2035 and 2062 (assuming the exercise of the Company's options to
extend such lease), respectively.

31, 1995.
(2) Total base rent for the year ended December 31, 1995, determined in
accordance with generally accepted accounting principles ("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 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.
(3) Aggregate base rent received over their respective terms from all leases
in effect at December 31, 1995 minus all tenant improvements, leasing
commissions and other concessions for all such leases, 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."
(4) Base rent for the year ended December 31, 1995 divided by net rentable
square feet leased at December 31, 1995.
(5) Effective rent at December 31, 1995 divided by net rentable square feet
leased at December 31, 1995.
(6) Based on all leases at the respective Properties dated on or before
September 30, 1996. Occupancy for all Properties at December 31, 1996 was
approximately 88.2%.
(7) Excludes office space leased by the Company.
(8) For this Property, a lease 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.
(9) 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.
(10) For this Property, leases with Hughes Space & Communications for
approximately 101,000 rentable square feet are written on a full service
gross basis except that there is no Expense Stop.
(11) This Property is an Acquisition Property.
(12) For this Property, the lease is written on a triple net basis.
(13) This Industrial Property was vacant until April 1995. The tenant began
paying rent in mid-October 1995 at an annual rate of $4.40 per rentable
square foot.
(14) 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.
(15) This lease terminates on December 31, 1996.
(16) 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.
(17) The leases for this Industrial Property are written on a modified triple
net basis, with the tenants responsible for estimated allocated common
area expenses.

THE COMPANY'S SOUTHERN CALIFORNIA SUBMARKETS

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 Company's Office and Industrial 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 and 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 in 1991 and 1992 of nearly 20.0% to a level at
the end of 1996 of under 17.0%. At September 30, 1996, the vacancy rate for the
Southern California Area Office Properties was approximately 6.9%. Vacancy
rates in the industrial space market in the Southern California Area have
decreased from a high of nearly 14% in 1992 to approximately 7.6% at December
31, 1996. At September 30, 1996, the vacancy rate for the Southern California
Area Industrial Properties was approximately 7.0%.

As of December 31, 1995, the Southern California Area had a total population
of approximately 15.6 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 217,000 persons. Of the total population at
December 31, 1995, approximately 9.2 million and 2.6 million persons lived in
Los Angeles and Orange Counties, respectively, the counties in which all but
five of the Properties are located. Annual estimated growth in population over
the next five years in these counties is expected to be approximately 94,000
and 32,000 persons, respectively. See "Business and Properties--The Company's
Southern California Submarkets."

THE FINANCING

The Company, on behalf of the Operating Partnership, has obtained a written
commitment for mortgage loans of $96.0 million (the "Mortgage Loans") from
Morgan Guaranty Trust Company of New York, an affiliate of J.P. Morgan & Co.,
the closing of which is a condition to the consummation of the Offering. The
proceeds of the Mortgage Loans will principally be used to repay existing
indebtedness on the Properties. The Mortgage Loans consist of: (i) an
$84.0 million mortgage loan secured by certain of the Properties (the "$84.0
Million Loan") and (ii) a $12.0 million mortgage loan secured by the SeaTac
Office Center (the "SeaTac Loan"). The $84.0 Million Loan requires monthly
principal and interest payments based on a fixed rate equal to the sum of the
interest rate for U.S. Treasury Securities maturing 8 years from the date of
the closing of the $84.0 Million Loan plus 1.75%, and will amortize over a 25-
year period, maturing in 2005. The Company presently anticipates that the $84.0
Million Loan will be incurred by a limited partnership which is wholly-owned by
the Company and the Operating Partnership and structured to be a "bankruptcy
remote" financing vehicle. The Properties to be pledged as collateral for the
$84.0 Million Loan will be transferred to such limited partnership. The SeaTac
Loan requires monthly payment of interest computed at a variable rate and has a
term of six months. Principal and interest under the SeaTac Loan will be full
recourse to the Company. The Company has financed the SeaTac Office Center in
this manner in order to provide flexibility to obtain additional financing
secured by the SeaTac Office Center if the Company leases additional space at
this Property. In connection with the $84.0 Million Loan, the Company will pay
fees equal to .50% of the total principal amount, or $420,000, and will
reimburse the lender for its costs and expenses. In connection with the SeaTac
Loan, the Company will pay fees equal to 1.5% of the total principal amount, or
$180,000, and will reimburse the lender for its costs and expenses. The
Mortgage Loans may, at the discretion of the lender, be included in a future
securitized financing transaction.

15
<PAGE>

The Company is currently negotiating with Morgan Guaranty Trust Company of
New York, on behalf of the proposed lenders, a $100.0 million revolving Credit
Facility (the Credit Facility, together with the Mortgage Loans, the
"Financing") which the Company, on behalf of the Operating Partnership, expects
to enter into shortly after the consummation of the Offering. The availability
of funds under the Credit Facility is expected to be subject to the value of
collateral securing the facility and the Company's compliance with a number of
customary financial and other covenants on an ongoing basis. The Company
expects that, initially, approximately $50.0 million will be available under
the Credit Facility. The Company also will have working capital cash reserves
of approximately $76 million and capital expenditure cash reserves of
approximately $2.5 million upon consummation of the Offering. The Credit
Facility and the working capital cash reserves will be used primarily to
finance acquisitions of additional properties. The Credit Facility will also be
available to refinance the SeaTac Loan. Payment of principal and interest on
the Credit Facility is expected to be secured by certain of the Properties. In
addition, borrowings under the Credit Facility are expected to be recourse
obligations to the Company and the Operating Partnership. In connection with
the Credit Facility, the Operating Partnership will pay fees equal to 1.0% of
the total commitment under the Credit Facility, or $1.0 million, and will
reimburse the lender for its costs and expenses.

DISTRIBUTION POLICY

The Company presently intends to make regular quarterly distributions to
holders of its Common Stock. The first distribution, for the period commencing
upon the consummation of the Offering and ending March 31, 1997, is anticipated
to be approximately $.2583 per share (which is equivalent to a quarterly
distribution of $.3875 per share or an annual distribution of $1.55 per share)
which results in an initial annual distribution rate of 6.74%. The Company does
not expect to change its estimated distribution rate if any of the
Underwriters' over-allotment option is exercised. The Company currently expects
to distribute approximately 90.7% of estimated cash available for distribution
for the 12 months following the consummation of the Offering. Units and shares
of Common Stock will receive equal distributions. The Board of Directors may
vary the percentage of cash available for distribution which is distributed if
the actual results of operations, economic conditions or other factors differ
from the assumptions used in the Company's estimates.

The Company established its initial distribution rate based on estimated cash
flow for the 12 months following the consummation of the Offering and the
Formation Transactions which the Company anticipates to be available for
distribution, taking into account rents under existing leases, estimated
operating expenses, capital improvements, debt service requirements, known
contractual commitments, and estimated amounts for recurring tenant
improvements and leasing commissions. To 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. See "Distribution
Policy."

The Company's estimate of the initial distribution rate for the Common Stock
was based on the Company's estimate of cash available for distribution, which
is being made solely for the purpose of setting the initial distribution rate
and is not intended to be a projection or forecast of the Company's results of
operations or of its liquidity. The Company believes that its estimate of cash
available for distribution constitutes a reasonable basis for setting the
initial distribution rate. However, no assurance can be given that the
Company's estimate will be accurate. See "Risk Factors--Distribution Payout
Percentage."

<PAGE>

TAX STATUS OF THE COMPANY

The Company intends to elect to be taxed 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 and believes its organization
and proposed method of operation will enable it to meet the requirements for
qualification as a REIT. To maintain REIT status, an entity must meet a number
of organizational and operational requirements, including a requirement that it
currently distribute at least 95% of its REIT taxable income (determined
without regard to the dividends paid deduction and by excluding net capital
gains) to its stockholders. As a REIT, the Company generally will not be
subject to federal income tax on net income it distributes currently to its
stockholders. If the Company fails to qualify as a REIT in any taxable year, it
will be subject to federal income tax at regular corporate rates and may not be
able to qualify as a REIT for the four subsequent taxable years. See "Risk
Factors--Adverse Consequences of Failure to Qualify as a REIT" and "Federal
Income Tax Considerations." Even if the Company qualifies for taxation as a
REIT, the Company may be subject to certain federal, state and local taxes on
its income and property. In addition, the Services Company will be subject to
federal and state income tax at regular corporate rates on its net income.

SUMMARY FINANCIAL DATA

The following table sets forth certain financial data on a pro forma basis
for the Company, and on an historical basis for the Kilroy Group, which consist
of the combined financial statements of the Kilroy Group (the "Combined
Financial Statements") whose financial results will be consolidated in the
historical and pro forma financial statements of the Company. 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, 1994, 1995 and September
30, 1996 and for each of the three years in the period ended December 31, 1995
and the nine months ended September 30, 1995 and 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 selected combined historical
financial and operating information as of December 31, 1993, 1992 and 1991, and
for the years ended December 31, 1992 and 1991, 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 the operating information for
the unaudited periods. The pro forma data assume the completion of the
Formation Transactions, including acquisition of the Acquisition Properties and
the consummation of the Offering and the Financing, and use of the aggregate
net proceeds therefrom as described under "Use of Proceeds" 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 does not give
effect to the recent extension of the tenant lease with Hughes Space &
Communications with respect to space leased in the Office Property located at
2250 E. Imperial Highway, El Segundo, California and a portion of the space
leased in the Office Property located at 2240 E. Imperial Highway, El Segundo,
California. 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
12,600,000 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 unit holders (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 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 1996 and 1995, 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 notes (9), (10) and (11) under the
caption "Distribution Policy" and 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.

RISK FACTORS

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, in
connection with an investment in the shares of Common Stock offered hereby.

CONFLICTS OF INTEREST

Certain Limited Partner Approval Rights. While the Company will be the sole
general partner of the Operating Partnership, and generally will have full and
exclusive responsibility and discretion in the management and control of the
Operating Partnership, certain provisions of the Partnership Agreement place
limitations on the Company'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 the Company
which will represent 82.6% of all Units outstanding upon consummation of the
Offering), 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 Units representing limited partner interests (excluding Units
held by the Company): (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 the seventh anniversary of the consummation of the Offering,
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, 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 Units (including Units held by the Company) and without
meeting certain other criteria with respect to the consideration to be
received by the limited partners. In addition, the Company 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 the Company's ability to act as described
above may result in the Company 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, holders of Units may suffer different and
more adverse tax consequences than the Company upon the sale or refinancing 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 the Company, as the sole
general partner of the Operating Partnership, will have the authority (subject
to certain limited partner approval rights described below) 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 the
Properties, even though such a sale might otherwise be financially
advantageous to the Company, or may seek to influence the Company to refinance
a Property 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 will represent 82.6% of all Units
outstanding upon consummation of the Offering), 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 the seventh
anniversary of the consummation of the Offering, 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."

20
<PAGE>

Failure to Enforce Terms of Certain Agreements. As recipients of Units in
the Formation Transactions, John B. Kilroy, Sr., as Chairman of the Company's
Board of Directors, and John B. Kilroy, Jr., as the Company's President and
Chief Executive Officer and a director of the Company, will 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 transfer to the
Operating Partnership of their interests in the Properties and other assets to
be acquired by the Company and relating to the Company's option to purchase
certain additional properties owned by entities controlled by them. See
"Business and Properties--Development, Leasing and Management Activities--
Excluded 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 Continuing Investors will provide indemnities in connection with
such transfers, such indemnities would be impaired to the extent that such
Continuing Investors have other obligations, including obligations for taxes
arising from the Formation Transactions or 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 and Bylaws which require that at least a majority of the
directors be Independent Directors, (ii) provisions in the Company's Bylaws
which require that a majority of the Independent Directors approve
transactions between the Company and members of the Kilroy Group, including
the enforcement of terms of the transfers of the Properties to the Operating
Partnership and the exercise of the options with respect to the Excluded
Properties, and the sale or refinancing of the Properties and (iii) the
requirement that the members of the Board of Directors that are Continuing
Investors (John B. Kilroy, Jr. and John B. Kilroy, Sr.) enter into
noncompetition agreements with the Company. The provisions contained in the
Company's Articles of Incorporation can be modified only with the approval of
two-thirds of the shares of the Company's capital stock outstanding and
entitled to vote thereon, and the provisions contained in the Company's Bylaws
can be modified only with the approval of a majority of either the Company's
Board of Directors or the shares of the Company's capital 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. will have controlling ownership interests in a complex of
three office properties which are located in the El Segundo submarket in which
four of the Office Properties and four of the Industrial Properties are
located. These properties will be managed by the Operating Partnership and
certain of the Company's officers, directors and employees will spend an
immaterial portion of their time and effort managing these interests and
Calabasas Park Centre, an undeveloped approximately 66-acre site (representing
approximately 45 developable acres net of acreage required for streets and
contractually required open areas). The Kilroy Group is actively marketing for
sale all but 18 acres of Calabasas Park Centre. Certain of the Company's
officers, directors and employees will 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 properties
located on North Sepulveda Boulevard in El Segundo will be managed by the
Operating Partnership pursuant to a management agreement on market terms. With
respect to Calabasas Park Centre, the officers, directors and employees of the
Company will spend an immaterial amount of time in connection with the
entitlement, marketing and sales of such parcels. Calabasas Park Centre will
be managed by the Services Company pursuant to a management agreement on
market terms. The implementation of the arrangements relating to each of these
properties will involve a conflict of interest with John B. Kilroy, Sr. and
John B. Kilroy, Jr. The Kilroy Group holds certain other real estate interests
which are not being 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

21
<PAGE>

Company's portfolio and the properties are not consistent with the Company's
strategy. See "Business and Properties--Excluded Properties."

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 the Code,
commencing with its taxable year ending December 31, 1997. Although management
believes that it will be organized and will operate in such a manner, no
assurance can be given that the Company will be organized or will 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 (some on an annual
and others on a quarterly basis) 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 ("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 to be held by the Operating Partnership will be less than 5%
of the value of the Company's total assets, based on the initial allocation of
Units among participants in the Formation Transactions and the Company's
opinion regarding the maximum value that could be assigned to the expected
assets and net operating income of the Services Company after the Offering. In
rendering its opinion as to the qualification of the Company as a REIT, Latham
& Watkins is relying 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 will be 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, the Company's net income, if any, from the third-party development
conducted through the Services Company will be subject to federal income tax
at regular corporate tax rates. See "Federal Income Tax Consequences--Services
Company."

22
<PAGE>

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

Tax Liabilities. The Services Company will be 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 Company to its stockholders.

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, upon consummation of the Offering, the Operating
Partnership will own 100% 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. will 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 it is anticipated that the Company will receive 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 will not be able to elect directors or officers of
the Services Company and, therefore, the Company will 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."

NO APPRAISALS; CONSIDERATION TO BE PAID FOR PROPERTIES AND OTHER ASSETS MAY
EXCEED THEIR FAIR MARKET VALUE. No independent valuations or appraisals of the
Properties were obtained in connection with the Formation Transactions. The
valuation of the Company has been determined by considering the enterprise
value of the Company as a going concern based primarily upon a capitalization
of estimated and anticipated Funds from Operations (as defined) and cash
available for distribution and the other factors discussed in this Prospectus
under "Distribution Policy" and "Underwriting," rather than an asset-by-asset
valuation based on historical cost or current market value. This methodology
has been used because management believes it is appropriate to value the
Company as an ongoing business rather than with the view to values that could
be obtained from a liquidation of the Company or of individual assets owned by
the Company. Accordingly, there can be no assurance that the consideration
paid by the Company will not exceed the fair market value of the Properties
and other assets acquired by the Company. A valuation of the Company
determined solely by appraisals of the Properties and other assets of the
Company may result in a significantly lower valuation of the Company from that
which is reflected by the initial public offering price per share set forth on
the cover of this Prospectus, which also takes into account the businesses of
the Services Company, the earnings of the Properties and the going concern
value of the Company. See "Underwriting." Since the liquidation value of the
Company is likely to be significantly less than the value of the Company as a
going concern, stockholders may suffer a significant loss in the value of
their shares if the Company were required to sell its assets.

The valuation of the Company's development, leasing and management services
business has been derived, in part, from a capitalization of the revenue
derived from the Company's contracts with third parties for real estate
development, leasing and management services. Upon consummation of the
Offering, the Company expects to provide through the Operating Partnership
leasing and management services, and through the Services Company development
services.

The consideration paid and the allocation of Units of the Operating
Partnership among the participants in connection with the Formation
Transactions were not determined by arm's-length negotiations. Since no

23
<PAGE>

appraisals of the Properties and other assets were obtained, the value of the
Units allocated to participants in the Formation Transactions may exceed the
fair market value of their ownership of such Properties and assets. The terms
of the option agreements relating to the Excluded Properties also were not
determined by arm's-length negotiations, and such terms may be less favorable
to the Company than those that may have been obtained through negotiations
with a third party. In addition, approximately $37.2 million of mortgage
indebtedness guaranteed by John B. Kilroy, Sr., of which $8.7 million is also
guaranteed by John B. Kilroy, Jr., and personal indebtedness of approximately
$3.4 million of John B. Kilroy, Sr., will be repaid in connection with the
Formation Transactions. See "--Conflicts of Interest," "Use of Proceeds" and
"Formation and Structure of the Company."

CASH FLOW FROM DEVELOPMENT ACTIVITIES IS UNCERTAIN. 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 which are subject to the risks inherent with development and general
economic conditions. In addition, development activities will be 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 such anticipated cash flows. See "Risk Factors--Real
Estate Investment Considerations--Risks of Real Estate Acquisition and
Development." Also, these development activities generally will be conducted
by the Services Company. Accordingly, cash flow from these activities will be
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. Twenty-two of the 26 Properties,
comprising an aggregate of approximately 2.7 million rentable square feet
(representing approximately 80.4% of the aggregate rentable square feet of all
of the Properties), are located in Southern California. Consequently, the
Company's performance will be linked to economic conditions and the demand for
office, industrial and retail 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. See "Business and Properties--The Company's Southern
California Submarkets." Although the recently announced disposition of defense
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 Company's Properties. Any
decline in the Southern California economy generally may result in a material
decline in the demand for office, industrial and retail space, 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. See "Business and
Properties--The Company's Southern California Submarkets."

In addition, eight Office Properties, representing approximately 64.9% of
the aggregate office space of all of the Office Properties, are located in two
office parks in El Segundo, California, and Long Beach, California,
respectively.

DEPENDENCE ON SIGNIFICANT TENANTS. The Company's ten largest office tenants
represented approximately 46.3% of annual base rent for the year ended
December 31, 1995 (giving pro forma effect to a recent extension of a lease
with Hughes Space & Communications with respect to two of the Office
Properties located at Kilroy Airport Center at El Segundo), and its ten
largest industrial tenants represented approximately 16.1% of annual base rent
for the same period. Of this amount, its largest tenant, Hughes Space &
Communications, currently leases approximately 495,000 rentable square feet of
office space in Kilroy Airport Center at El Segundo, representing
approximately 25.3% of the Company's total base rent revenues for the year
ended December 31, 1995 (giving pro forma effect to the Hughes Space &
Communications lease extension). 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

24
<PAGE>

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 will be based principally on cash available for
distribution from the Properties. Increases in base rent under the leases of
the Properties or the payment of rent in connection with future acquisitions
will increase the Company's cash available for distribution to stockholders.
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 will also be
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, will 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. In
such event, the trading price of the Common Stock may be adversely affected.

To obtain the favorable tax treatment associated with REITs, the Company
generally will be 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 will
be 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 will also be 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.

The Company intends 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.

25
<PAGE>

The Company's income would be adversely affected if a significant number of
tenants were unable to pay rent or if office, industrial or retail 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 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 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. All of the Properties are in developed areas where there are
generally other properties of the same type. Competition from other office,
industrial and retail 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 September 30, 1996, the Company's weighted average renewal rate, based
on net rentable square footage, was 71.7% for the Properties located in the
Southern California Area and 50.9% for the Properties overall. The lower
overall retention rate is due primarily to the termination in 1993 of a lease,
scheduled to expire in 1995, for 211,000 square feet at the SeaTac Office
Center.

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 adversely affect the Company and its ability
to make distributions. During the three calendar years ending December 31,
1999, the Company will have expiring Office Property leases covering
approximately 408,000 net rentable square feet, and Industrial Property leases
covering approximately 92,900 net rentable square feet. For the year ended
December 31, 1995, such leases had a weighted average annual base rent per net
rentable square foot of approximately $18.81 and $5.97, respectively. For the
nine-month period ended September 30, 1996, the Company entered into 31 Office
Property lease transactions for an aggregate of approximately 342,000 net
rentable square feet with a weighted average initial annual base rent per net
rentable square foot of approximately $19.52 (excluding the Thousand Oaks
Office Property where the Company entered into one lease transaction with an
initial annual base rent per net rentable square foot of $24.00). For the 12-
month period ending December 31, 1996, the Company entered into one Industrial
Property lease transaction for approximately 62,500 net rentable square feet
with an initial annual base rent per net rentable square foot of $6.36. See
"Business and Properties--General" and "--Lease Expirations."

Ground Leases. The Company's eight Office Properties located at Kilroy
Airport Center in Long Beach (assuming consummation of the acquisition of
Kilroy Long Beach Phase I concurrent with the consummation of the Offering)
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
Properties located on the respective parcel, with the landowner becoming the
owner of such Properties 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 the Properties or increased rental expense to the
Company. The ground leases for the Kilroy Airport Center Long Beach

26
<PAGE>

will expire in 2035. See "Business and Properties--Office Properties--Kilroy
Long Beach." The ground leases for the SeaTac Office Center (including renewal
options) will expire in 2062. See "Business and Properties--Office
Properties--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
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.

In addition to the Development Properties, the Company will 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.

The Company anticipates that 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 could 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 plans in the future to 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 will not initially possess the same level of familiarity with new
types of commercial development or new markets, which could adversely affect
its ability to acquire or develop properties in any new localities or to
realize expected performance.

Uninsured Loss. 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
copayments, 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. Although the Company expects to have
earthquake insurance on a substantial portion of its Properties,

27
<PAGE>

such insurance will not be 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 may incur uninsured losses or losses due to
deductibles or co-payments on insured losses. See "Business and Properties--
Uninsured Losses from Seismic Activity."

Risks Involved in Property Ownership Through Partnerships and Joint
Ventures. Although the Company will own fee simple interests in the Properties
(other than Kilroy 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, that such
partners or co-venturers might at any time have economic or other business
interests or goals which are inconsistent with the business interests or goals
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
will, however, 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 will be 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. 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 "The Financing."

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 Company's Board of
Directors and stockholders), the Company's Board of Directors will determine
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. Existing stockholders will
have no preemptive right 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.

28
<PAGE>

Risks Involved in Acquisitions Through Partnerships or Joint Ventures. The
Company may invest in office and industrial properties through partnerships or
joint ventures instead of purchasing such properties directly or through
wholly-owned subsidiaries. Partnership or joint venture investments may, under
certain circumstances, involve risks not otherwise present in a direct
acquisition of properties. These include the risk that the Company's co-
venturer or partner in an investment might become bankrupt; a co-venturer or
partner might at any time have economic or business interests or goals which
are inconsistent with the business interests or goals of the Company and a co-
venturer or partner might 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.

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
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 intends to operate its business in a manner that will not
require the Company to register under the Investment Company Act of 1940 and
stockholders will 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
will own and manage the Properties through its investment in the Operating
Partnership in which it will own an approximately 82.6% economic interest (or
an 84.5% interest if the Underwriters' over-allotment option is exercised in
full). The remaining interests in the Operating Partnership will be owned by
the Continuing Investors. Although the number of limited partnership Units was
designed to result in a distribution per Unit equal to a distribution per
share of Common Stock, such distributions would be equal only if the Company
distributes to stockholders all amounts it receives in distributions from the
Operating Partnership. See "Formation Transactions--Comparison of Common Stock
and Units." 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 CONTINUING INVESTORS. John B. Kilroy, Sr., the
Company's 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 Continuing Investors, Units exchangeable for
shares of Common Stock equal to approximately 17.4% of the total outstanding
shares (and, together with options exercisable for shares of Common Stock,
18.8% of the total outstanding shares). In addition, the Messrs. Kilroy will
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 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 Company's 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 (i) the dissolution of the
Operating Partnership, or (ii) prior to the seventh anniversary of the
consummation of the Offering, 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 Company's Articles of
Incorporation and Bylaws, and certain provisions of the Operating
Partnership's 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
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 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 of the Company 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 21% 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. Following the consummation of the Offering, the Board of
Directors of the Company will be divided into three classes serving staggered
three-year terms. The terms of the first, second and third classes will expire
in 1998, 1999 and 2000, respectively. Directors for each class will be chosen
for a three-year term upon the expiration of the current class' 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 will be issued or outstanding at the consummation of the Offering. 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

30
<PAGE>

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
Company's Chairman of the Board, 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.
The Company has entered into employment agreements with John B. Kilroy, Jr.,
Jeffrey C. Hawken, Richard E. Moran Jr. and Campbell Hugh Greenup. See
"Management--Employment Agreements."

DISTRIBUTION PAYOUT PERCENTAGE. The Company's expected annual distributions
for the 12 months following consummation of the Offering of $1.55 per share
are expected to be approximately 90.7% of estimated cash available for
distribution. If cash available for distribution generated by the Company's
assets for such 12-month period is less than the Company's estimate, or if
such cash available for distribution decreases in future periods from expected
levels, the Company's ability to make the expected distributions would be
adversely affected. Any such failure to make expected distributions could
result in a decrease in the market price of the Common Stock. See
"Distribution Policy."

HISTORICAL OPERATING LOSSES OF THE 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 of the Company has resulted in net
losses for financial reporting purposes in each of the last five fiscal years.
Historical operating results of the Office and Industrial Properties may not
be comparable to future operating results of the Company because, prior to the
completion of the Offering and the Formation Transactions, the Office and
Industrial Properties were encumbered with greater levels of debt (which has
the effect of reducing net income) than that with which the Company intends to
operate. In addition, the historical results of operations do not reflect the
acquisition and development of any of the Acquisition Properties or the
Development Properties. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations." However, there can be no assurance that
the Company will acquire the Acquisition Properties or acquire and
successfully develop any of the Development Properties, and, even if such
Properties are acquired and successfully developed, that they will not
experience losses in the future.

NO LIMITATION ON DEBT. The Board of Directors currently intends to fund
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. Upon completion of the Offering and the Formation Transactions,
the debt to total market capitalization ratio of the Company will be
approximately 21.5%. 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

31
<PAGE>

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 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.

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, effective beginning in 1992, 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 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.

The Company believes that the Properties are in compliance in all material
respects with all federal, state and local laws, ordinances and regulations
regarding hazardous or toxic substances or petroleum products. 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 present
properties.

32
<PAGE>

but do not include soil sampling or subsurface investigations. In connection
with the preparation of the Phase I environmental survey with respect to
Kilroy Long Beach Phase I, interviews of certain individuals formerly employed
at the site documented in a historical site assessment survey revealed the
site's possible prior use as a Nike air defense command center or missile
facility. Further investigation performed by the Company's environmental
consultants and by the Company did not reveal any additional information with
respect to such use of the site. 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.

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
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 Company's 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 Southern California Northridge earthquake on January 17,
1994. 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 or that
other requirements affecting the Properties will not be imposed which would
require significant unanticipated expenditures by the Company and could have
an adverse effect on the Company's 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."

IMMEDIATE AND SUBSTANTIAL DILUTION. As set forth more fully under
"Dilution," as of September 30, 1996, the Properties to be contributed by the
Kilroy Group in exchange for Units in the Operating Partnership had a pro
forma net tangible book value for financial reporting purposes (giving effect
to the Offering) of approximately $129.7 million, or $10.29 per share of
Common Stock. As a result, the pro forma net book value per share of Common
Stock of the Company after the consummation of the Offering and the Formation
Transactions will be less than the initial public offering price of $23.00 per
share. The purchasers of Common Stock offered hereby will experience immediate
and substantial dilution of $12.71 per share of Common Stock in the net
tangible book value of the shares of Common Stock. See "Dilution."

33
<PAGE>

NO PRIOR PUBLIC MARKET. Prior to the Offering, there has been no public
market for the Common Stock, and there can be no assurance that an active
trading market will develop as a result of the Offering or, if a trading
market does develop, that it will be sustained or that the shares of Common
Stock will be resold at or above the initial public offering price. 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. The initial
public offering price of the Common Stock offered hereby has been determined
through negotiations between the Company and the representatives (the
"Representatives") of the Underwriters. Among the factors considered in such
negotiations, in addition to prevailing market conditions, were distribution
rates and Funds from Operations of publicly traded REITs that the Company and
the Representatives believe to be comparable to the Company, estimates of the
business potential and earnings prospects of the Company, and the current
state of the Company's industry and the economy as a whole. The initial public
offering price does not necessarily bear any relationship to the Company's
book value, assets, financial condition or any other established criteria of
value and may not be indicative of the market price for the Common Stock after
the Offering. See "Underwriting."

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.

SHARES AVAILABLE 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 and the Formation Transactions, the
Company will have 12,600,000 shares of Common Stock outstanding (including
100,000 restricted shares of Common Stock issued to an officer of the Company
who is not a Continuing Investor and excluding 1,875,000 shares of Common
Stock subject to the Underwriters' over-allotment option), of which all but
the 100,000 restricted shares of Common Stock will be freely tradeable in the
public market by persons other than "affiliates" of the Company without
restriction or registration under the Securities Act. The Common Stock issued
to an officer and all of the shares of Common Stock that are issuable upon the
redemption of Units will be deemed to be "restricted securities" within the
meaning of Rule 144 under the Securities Act 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
of the Securities Act. In general, upon satisfaction of certain conditions,
Rule 144 of the Securities Act permits the sale of certain amounts of
restricted securities two years following the date of acquisition of the
restricted securities from the Company and, after three years, permits
unlimited sales by persons unaffiliated with the Company.

It is expected that the Operating Partnership will issue an aggregate of
2,652,374 Units to executive officers, directors and other Continuing
Investors in connection with the formation of the Company which, after two
years following the receipt of such Units, may be redeemed by the Operating
Partnership at the request of the holders 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 antidilution adjustments and, with
respect to 50% of the Units to be issued to John B. Kilroy, Sr., John B.
Kilroy, Jr. and Kilroy Industries, the obligation of such Continuing Investors
to indemnify the Company in connection with the Formation Transactions. See
"Formation and Structure of the Company--Allocation of Consideration in the
Formation Transactions." However, if the Company does not elect to exchange
such Units for shares, a Continuing Investor 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

34
<PAGE>

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 Available for Future Sale--Redemption Rights/Exchange
Rights/Registration Rights." It is expected that immediately after the
Offering the Company will grant options to purchase an aggregate of
approximately 900,000 shares of Common Stock at the initial public offering
price to certain directors, executive officers and other employees of the
Company and an additional approximately 500,000 shares of Common Stock will be
reserved for issuance 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 Excluded Properties. See "The Company--Growth
Strategies" and "Business and Properties--Development, Management and Leasing
Activities--Excluded Properties." The Company has agreed to file and generally
keep continuously effective beginning two years after the completion of the
Offering a registration statement covering the issuance of shares upon the
exchange of 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 Continuing Investors and certain other persons. See "Shares
Available for Future Sale." The Company also anticipates that it will file a
registration statement with respect to the shares of Common Stock issuable
under the Stock Incentive Plan following the consummation of the Offering.
Such registration statements and registration rights generally will allow
shares of Common Stock covered thereby, including shares of Common Stock
issuable upon exchange of 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) each of
the Continuing Investors has agreed not to, directly or indirectly, offer,
sell, offer to sell, contract to sell, pledge, grant any option to purchase or
otherwise sell or dispose (or announce any offer, sale, offer of sale,
contract of sale, pledge, grant of any option to purchase or other sale or
disposition) 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 for
a period of two years from the date of this Prospectus, and (ii) the Company
has agreed not to offer, sell, offer to sell, contract to sell, pledge, grant
any option to purchase or otherwise sell or dispose (or announce any offer,
sale, offer of sale, contract of sale, pledge, grant of any option to purchase
or other sale or disposition) of any (other than pursuant to the Stock
Incentive Plan) 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, 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. At the conclusion of the
two-year period referenced in clause (i) above, Common Stock issued upon the
subsequent exchange of 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 Kilroy
Industries in connection with the Formation Transactions will be pledged to
secure their indemnification obligations pursuant to an agreement with the
Company. See "Formation and Structure of the Company." Future sales of the
shares of Common Stock described above could have an adverse effect on the
market price of the shares of Common Stock and the existence of Units,
options, shares of Common Stock reserved for issuance as restricted shares of
Common Stock or upon exchange of Units and the exercise of options and
registration rights referred to above may adversely affect the terms upon
which the Company may be able to obtain additional capital through the sale of
equity securities. See "Shares Available for Future Sale" and "Underwriting."
Such sales may be increased or accelerated to the extent that the Continuing
Investors have personal obligations, including obligations for taxes, which
may arise as a result of the Formation Transactions or prior transactions.

FORMATION AND STRUCTURE OF THE COMPANY

Kilroy Realty was formed in September 1996 and the Operating Partnership was
formed in October 1996. The Services Company will be formed prior to
consummation of the Offering.

FORMATION TRANSACTIONS

Prior to or simultaneous with the consummation of the Offering, the Company,
the Operating Partnership, the Services Company and the Continuing Investors
will engage in the Formation Transactions designed to enable the Company to
continue and expand the real estate operations of KI, to facilitate the
Offering, 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 the existing owners of the Properties. The
Formation Transactions are as follows:

. Pursuant to the Omnibus Agreement, the Operating Partnership may require
the contribution to the Operating Partnership of all of the Continuing
Investors' interests in the Properties (other than the Acquisition
Properties), the assets used to conduct the leasing, management and
development activities (principally office equipment), the assignment of
contract rights in connection with development opportunities at Kilroy
Airport Center Long Beach, and the rights with respect to the purchase
of each of the Acquisition Properties, in exchange for Units
representing limited partnership interests in the Operating Partnership.
The book value to the Continuing Investors of the assets to be
contributed to the Operating Partnership is a negative $113.2 million
and the value of the Units representing limited partnership interests in
the Operating Partnership to be received by the Continuing Investors is
$61.0 million, assuming a Unit value equal to the initial public
offering price of $23.00 per share. Pursuant to the terms of the Omnibus
Agreement, the Operating Partnership has the right to acquire the
Properties and the other assets described above from the Continuing
Investors in exchange for Units through December 31, 1998, the date the
Omnibus Agreement terminates. Following the consummation of the Offering
and the Formation Transactions, the Units received by the Continuing
Investors will constitute in the aggregate an approximately 17.4%
limited partnership interest in the Operating Partnership.

. The Company, through the Operating Partnership, will borrow
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 will apply the aggregate of the net Offering
proceeds and the Mortgage Loans toward the repayment of existing
mortgage indebtedness on certain of the Properties, the purchase of the
Acquisition Properties and payment of its expenses arising in connection
with the Offering and the Financing. See "Use of Proceeds."

. Forty-seven of the current 69 employees of KI will become 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

36
<PAGE>

Officer and Secretary, and Mr. Campbell Hugh Greenup, General Counsel)
who are not Continuing Investors and 43 other operating and
administrative employees. See "Management."

. The Operating Partnership or the Services Company will enter into
Management Agreements with respect to each of the Excluded Properties.
Pursuant to the terms of each of the Management Agreements, the
Operating Partnership or the Services Company, as applicable, will have
exclusive control and authority (subject to an operating budget to be
approved by the owners of each property) over each of the Excluded
Properties for a term of 24 months. If any of the Excluded 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 to be provided under the Management Agreements, the
Company will receive a monthly property management fee as well as any
applicable leasing commissions. See "Business and Properties--Excluded
Properties."

. Concurrent with the consummation of the Offering, the Company will enter
into Option Agreements with partnerships controlled by John B. Kilroy,
Sr. and John B. Kilroy, Jr. granting to the Operating Partnership the
exclusive right to acquire (i) the approximately 18 undeveloped acres
located at Calabasas Park Centre for cash and (ii) the office property
located at North Sepulveda Boulevard, El Segundo for cash (or for Units
after the first anniversary of the Offering at the election of the
seller), and in each case pursuant to the other terms of the respective
Option Agreement. See "Business and Properties--Excluded 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.

As a result of the foregoing transactions, the Company will own 12,600,000
Units of the Operating Partnership (including 100,000 Units attributable to
the issuance by the Company of 100,000 restricted shares of Common Stock to
Mr. Moran), which will represent an approximately 82.6% economic interest in
the Operating Partnership, and the Continuing Investors will own 2,652,374
Units, which will represent the remaining approximately 17.4% economic
interest in the Operating Partnership. If the Underwriters' over-allotment
option is exercised in full and the net proceeds from the additional shares of
Common Stock sold by the Company are contributed to the Operating Partnership,
the Company's percentage ownership interest in the Operating Partnership will
increase to approximately 84.5%. The Company will be the sole general partner
and retain management control over the Operating Partnership.

Holders of Units will have the opportunity after two years following the
receipt of such Units 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 antidilution
adjustments and the obligation of certain of the Continuing Investors 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
Company's Articles of Incorporation, as applicable. See "Formation and
Structure of the Company--Allocation of Consideration in the Formation
Transactions," Under certain circumstances, 50% of the Units received by John
B. Kilroy, Sr., John B. Kilroy, Jr. and Kilroy Industries may be redeemed
prior to the second anniversary of the consummation of the Offering in
connection with the obligation of such Continuing Investors to indemnify the
Company in connection with the Formation Transactions. See "--Allocation of
Consideration in the Formation Transactions."

37
<PAGE>

Directors and John B. Kilroy, Jr. is President and Chief Executive Officer and
a director of the Company. Consent of the Continuing Investors to the
Formation Transactions was received on or before November 3, 1996 pursuant to
a private solicitation thereof in compliance with Regulation D.

REASONS FOR THE REORGANIZATION OF THE COMPANY

. Access to Capital. The Company's structure will, in the Company's
judgment, provide it with greater access to capital for refinancing and
growth. Sources of capital include the Common Stock sold in the Offering
and possible future issuances of debt or equity through public offerings
or private placements. The financial strength of the Company should
enable it to obtain financing at better rates and on better terms than
would otherwise be available to the Partnerships, some of which are
single asset entities.

. Growth of the Company. The Company's structure will allow stockholders,
including the Continuing Investors through their ownership of Units, an
opportunity to participate in the growth of the real estate market
through an ongoing business enterprise. In addition to the existing
portfolio of Properties, the Company gives stockholders an interest in
all future development by the Company and in the fee-producing service
businesses being contributed by the Company to the Services Company.

. Risk Diversification. The Company's structure provides stockholders a
diversification of risk and reward not available in single asset
entities by providing them with an equity interest in a REIT in which
there has been a pooling together of similar properties and by
consolidating the operating business and future development projects.

. Deleveraging. Upon completion of the Offering and the Formation
Transactions, the Company will have substantially reduced the debt
encumbering the Properties. This reduction, with a consequent reduction
in debt service, will increase the aggregate amount of cash available
for distribution to stockholders. The Formation Transactions also will
permit the Company to refinance its existing indebtedness at more
favorable rates.

. Liquidity. The equity interests in the Partnerships are typically not
marketable. The Company's structure allows stockholders, including the
Continuing Investors, the opportunity to liquidate their capital
investment through the disposition of Common Stock or Units. Beginning
on the second anniversary of the consummation of the Offering, holders
of Units will have the opportunity to have their Units redeemed by the
Operating Partnership for cash equal to the value of an equal number of
shares of Common Stock, or the Company may elect to exchange such Units
for an equivalent number of shares of Common Stock, provided, however,
if the Company does not elect to exchange such units for shares of
Common Stock, a holder of Units that is a corporation or 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 Company's Articles of Incorporation, as applicable.

. Public Market Valuation of Real Estate Assets. The Company's structure
may allow investors to benefit potentially from the current public
market valuation of REITs, which management believes is favorable in
light of the current private market valuation of comparable assets.

. Tax Deferral. The Formation Transactions provide to the Continuing
Investors the opportunity to defer the tax consequences that would arise
from a sale or contribution of their interests in the Properties and
other assets to the Company or to a third party.

The detriments of the Company's REIT status and structure as opposed to the
status and structure of the Partnerships include the following (see also "Risk
Factors"):

. Conflicts of Interest. Management of the Company will be subject to a
number of conflicts of interest in the operation of the Operating
Partnership as well as the formation of the Company. Among other

38
<PAGE>

conflicts, there will be no independent valuation or appraisal of the
Properties, and no arm's-length negotiation of the terms of the option
agreements relating to the Excluded Properties, and there can be no
assurance that the value given to the Continuing Investors by the
Company for such assets is equal to their fair market value. Because
John B. Kilroy, Sr. and John B. Kilroy, Jr. will be directors or
officers of the Company, they will have a conflict of interest with
respect to enforcing the agreements transferring their interest in
certain assets to the Company. In addition, because the Continuing
Investors and officers of the Company may suffer different tax
consequences than the Company upon the sale or refinancing of any of the
Properties, their interests regarding the timing and pricing of such
sale or refinancing may conflict with those of the Company. So long as
the Continuing Investors own more than 5% of the outstanding Units, the
Continuing Investors will be able to veto or preclude the sale of the
Office Property located at 2260 E. Imperial Highway at Kilroy Airport
Center at El Segundo at any time prior to the seventh anniversary of the
Offering. In addition, the Company is required to use its commercially
reasonable efforts to structure any merger, consolidation or other
business combination, any sale or other disposition of all or
substantially all of its assets, or any reclassification,
recapitalization or change of its outstanding equity interests, 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. See
"Partnership Agreement of the Operating Partnership--Certain Limited
Partner Approval Rights."

. Consent Rights of Limited Partners. The Company will be the sole general
partner of the Operating Partnership and will own and control 82.6% of
the ownership interests in the Operating Partnership. However, under the
terms of the Partnership Agreement, the Company may not withdraw as
general partner of the Operating Partnership or transfer or assign its
interest in the Operating Partnership without the consent of partners
holding in the aggregate at least 60% of all interests in the Operating
Partnership. See "Partnership Agreement of the Operating Partnership--
Transferability of Interests." In addition, until the seventh
anniversary of the Offering the general partner of the Operating
Partnership will not be able to dissolve the Operating Partnership, or
sell the Office Property located at 2260 E. Imperial Highway at Kilroy
Airport Center at El Segundo, without the consent of limited partners
holding in the aggregate more than 50% of all Units representing limited
partnership interests in the Operating Partnership, provided that the
limited partners own at least 5% of the outstanding Units (including
Units owned by the Company). See "Partnership Agreement of the Operating
Partnership--Certain Limited Partner Approval Rights." As a consequence
of the exercise of these consent and approval rights, the Company may be
precluded from taking action that 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."

. Influence of Certain Continuing Investors. John B. Kilroy, Sr., the
Company's 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 Continuing Investors, Units
exchangeable for shares of the Common Stock equal to approximately 17.4%
of the total outstanding shares. In addition, the Messrs. Kilroy will
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 in excess of 7.0% of the Common Stock. Consequently,
although the Messrs. Kilroy will not be able to take action on behalf of
the Company without the concurrence of other members of the Company's
Board of Directors, they will be able to block certain transactions by
the Operating Partnership and exert substantial influence over the
Company's affairs.

. Loss of Individual Asset Growth Opportunity. Any given asset may over
time outperform the Common Stock. Any investor who exchanges an interest
in a single asset for a smaller interest in a

39
<PAGE>

group of assets will receive a lower return on investment if the asset
from which the investor traded outperforms the Common Stock.

. No Anticipated Distributions from Asset Sales. Unlike the Partnerships,
in which the net proceeds from the sale of assets were generally
distributed to the partners, the Company is not expected to have
significant asset sales. Moreover, the Company may decide to reinvest
the proceeds from asset sales rather than distribute them to
stockholders. Although stockholders will have the ability to sell their
shares of Common Stock (subject to certain restrictions discussed
herein), they would not be able to rely upon the mere passage of time to
realize their share of the gains, if any, that might be recognized at
any point in time from a liquidation of all or part of the assets of the
Company.

. Public Market Valuation. Although the public market may value real
estate assets on a basis that is attractive in relation to private
market real estate values, there is no assurance that this condition, if
it exists, will continue. In the 1980s, REIT shares generally traded at
a discount to the underlying private market values of the REIT
properties, rather than at a premium. This condition could return. In
addition, an increase in interest rates could adversely affect the
market value of the shares of Common Stock.

. Costs of the Transaction. The aggregate expenses of the Offering,
including the underwriting discount, are expected to be approximately
$24.6 million. In addition, the Operating Partnership will incur costs
of approximately $1.8 million in the aggregate in connection with the
Financing.

. Costs of Operating Public Company. The Company expects to incur expenses
in connection with the requirements of being a public company, including
without limitation, preparation of financial statements and proxies,
printing and filing costs, directors' and officers' insurance, and legal
and accounting fees, estimated to be $1.0 million annually.

COMPARISON OF COMMON STOCK AND UNITS

Conducting the Company's operations through the Operating Partnership allows
the Continuing Investors to defer certain tax consequences by contributing
their interests in Properties to the Operating Partnership and also offers
favorable methods of accessing capital markets. Units in the Operating
Partnership will be held by the Continuing Investors and the Company. Each
Unit was designed to result in a distribution per Unit equal to a distribution
per share of Common Stock (assuming the Company distributes to its
stockholders all amounts it receives as distributions from the Operating
Partnership). Beginning two years following the consummation of the Offering,
each Unit issued in the Formation Transactions is redeemable by the Operating
Partnership at the request of the Unitholder for cash payable by the Operating
Partnership or, at the Company's option, the Company may exchange Units for
Common Stock on a one-for-one basis (subject to certain antidilution
adjustments and certain limitations on exchange to preserve the Company's
status as a REIT), provided, however, that if the Operating Partnership elects
to redeem such Units for cash, 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. There are, however, certain differences between the ownership of
Common Stock and Units, including:

. Voting Rights. Holders of Common Stock may elect the Board of Directors
of the Company, which, as the general partner of the Operating
Partnership, controls the business of the Operating Partnership.
Unitholders may not elect directors of the Company.

. Transferability. The shares of Common Stock sold in the Offering will be
freely transferable under the Securities Act by holders who are not
affiliates of the Company or the Underwriters. The Units and the shares
of Common Stock into which they are exchangeable are subject to transfer
restrictions under applicable securities laws and under the Partnership
Agreement, including the required consent of the general partner to the
admission of any new limited partner, and 50% of the Units of John B.
Kilroy, Sr., John B. Kilroy, Jr. and Kilroy Industries will be pledged
to secure certain indemnity obligations. See "Shares Available for
Future Sale" for a description of the Registration Rights Agreement
applicable to holders of Units.

40
<PAGE>

. Distributions. Because the relative tax basis of the contributions by
the public investors and the Continuing Investors are expected to be
different, it is possible that the public investors' distribution will
include a return of capital that exceeds that of the Continuing
Investors. See "Federal Income Tax Consequences."

ADVANTAGES AND DISADVANTAGES OF THE FORMATION TRANSACTIONS TO UNAFFILIATED
STOCKHOLDERS

The potential advantages of the Formation Transactions to unaffiliated
stockholders of the Company include 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 potential disadvantages of such transactions to unaffiliated
stockholders of the Company may be several, including the impact of shares
available for future sale and substantial and immediate 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 Properties to the Company and the
Operating Partnership and the terms of the option agreements relating to the
Excluded Properties. See the discussion of such matters under "Risk Factors."

BENEFITS OF THE FORMATION TRANSACTIONS TO THE CONTINUING INVESTORS

. improved liquidity of their interests in the Properties and increased
diversification of their investment;

. 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.

Set forth below are the (i) names of executive officers of the Company and
certain other persons involved in the Formation Transactions; (ii) net book
value of the interests of such persons in the Properties being transferred;

No third party determination of the value of the Properties was sought or
obtained in connection with the acquisition by the Operating Partnership of
the Properties, and the terms of each of the Option Agreements relating to the
Excluded Properties were not determined through arm's-length negotiations.
There can be no assurance that the aggregate value of the consideration
received by the participants in the Formation Transactions, including the
grant of the options relating to the Excluded Properties, is equivalent to the
fair market value of the properties and assets acquired by the Company and the
Operating Partnership in connection with the Formation Transactions. See "Risk
Factors--No Appraisals; Consideration to be Paid for Properties

<PAGE>

and Other Assets May Exceed their Fair Market Value" and "--Conflicts of
Interest--Competitive Real Estate Activities of Management."

DETERMINATION AND VALUATION OF OWNERSHIP INTERESTS

The Company's percentage interest in the Operating Partnership was
determined based upon the percentage of estimated cash available for
distribution required to pay estimated cash distributions to stockholders of
the Company representing an annual distribution rate equal to 6.74% of the
initial public offering price of the Common Stock of $23.00. The ownership
interest in the Operating Partnership allocated to the Company is equal to
this percentage of estimated cash available for distribution and the remaining
interest in the Operating Partnership will be allocated to the Continuing
Investors receiving Units in the Formation Transactions. The parameters and
assumptions used in deriving the estimated cash available for distribution are
described under the caption "Distribution Policy."

Based on the issuance of 12,500,000 shares of Common Stock in the Offering
plus 100,000 restricted shares of Common Stock to Richard E. Moran Jr. (who is
not a Continuing Investor), the Company will hold an approximately 82.6%
ownership interest in the Operating Partnership and the Continuing Investors
will hold an approximately 17.4% ownership interest in the Operating
Partnership. If the Underwriters' over-allotment option is exercised in full,
the Company will hold an approximately 84.5% ownership interest in the
Operating Partnership and the Continuing Investors will hold an approximately
15.5% ownership interest in the Operating Partnership.

In connection with the Offering, the Company did not obtain appraisals with
respect to the market value of any of the Properties or other assets that the
Company will own immediately after consummation of the Offering and the
Formation Transactions or an opinion as to the fairness of the allocation of
shares to the purchasers in the Offering. The initial public offering price
has been determined based upon the estimated cash available for distribution
and the factors discussed under the caption "Underwriting," rather than a
property by property valuation based on historical cost or current market
value. This methodology has been used because management believes it is
appropriate to value the Company as an ongoing business rather than with a
view to values that could be obtained from a liquidation of the Company or of
individual properties owned by them. See "Underwriting."

ALLOCATION OF CONSIDERATION IN THE FORMATION TRANSACTIONS

No independent valuations or appraisals of the Properties were obtained in
connection with the Formation Transactions. The allocation of Units among the
Continuing Investors was based primarily on the relative contributions to net
operating income and other factors relating to the value of the Company as an
on-going enterprise, and generally was not determined through arm's-length
negotiations. There can be no assurance that the fair market value of the
Properties transferred to the Company will equal the sum of the value of the
Units issued to the Continuing Investors.

Certain Continuing Investors (the "Indemnitors") have agreed pursuant to a
supplemental representations, warranties and indemnity agreement, a form of
which has been filed as an exhibit to the Registration Statement of which this
Prospectus is a part, to make certain representations and warranties
concerning the Properties, and have also agreed to indemnify the Company
against breaches of such representations and warranties. These representations
and warranties will survive the closing of the Offering until June 1998 and
the related indemnification obligations generally will be joint and several
among the Indemnitors. Fifty percent of the Units received by John B. Kilroy,
Sr., John B. Kilroy, Jr. and Kilroy Industries in the Formation Transactions
will be pledged to secure their indemnification obligations under the
supplemental representations, warranties and indemnity agreement.

FORMATION OF KILROY SERVICES, INC.

Prior to consummation of the Offering, Kilroy Services, Inc. will be 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 will own 100% of the voting common stock of the Services Company,
representing 5.0% of its economic value. The Operating Partnership will own
100% 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 anticipates receiving 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 will not be 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 initially will have three directors, including Campbell
Hugh Greenup, who also serves as the General Counsel of the Company, and
Jeffrey C. Hawken, who also serves as the Executive Vice President and Chief
Operating Officer of the Company. See "Management." In addition, the Services
Company will have a third and independent director. Campbell Hugh Greenup will
serve as the Services Company's President and Secretary, and David Armanetti
will serve as its Vice President of Development Services and Treasurer. Prior
to the Offering, Mr. Greenup was a Senior Vice President for Development of KI
and Mr. Armanetti was a Vice President for Development of KI.

THE COMPANY

GENERAL

The Company has been formed to succeed to the business of the Kilroy Group
consisting principally of a portfolio of Class A suburban office and
industrial buildings in prime locations primarily in Southern California, and
the Kilroy Group's real estate ownership, acquisition, development, leasing
and management businesses. Upon the consummation of the Offering and the
Formation Transactions, the Company (through the Operating Partnership) will
own 14 Office Properties encompassing an aggregate of approximately 2.0
million rentable square feet and 12 Industrial Properties encompassing an
aggregate of approximately 1.3 million rentable square feet. Eleven of the 14
of the Office Properties and 11 of the 12 Industrial Properties are located in
prime Southern California suburban submarkets (including a complex of three
Office Properties located in El Segundo, adjacent to Los Angeles International
Airport, presently the nation's second largest air-cargo port, and a complex
of five Office Properties located adjacent to the Long Beach Municipal
Airport). The Company also will own three Office Properties located adjacent
to the Seattle-Tacoma International Airport in the State of Washington and one
Industrial Property located in Phoenix, Arizona. As of September 30, 1996, the
Office Properties were approximately 79.8% leased to 130 tenants and the
Industrial Properties were approximately 93.7% leased to 20 tenants. The
average age of the Office Properties and the Industrial Properties is
approximately 12 years and 24 years, respectively. The Company developed and
leased all but two of the 14 Office Properties and all but five of the 12
Industrial Properties, and upon consummation of the Offering and acquisition
of the Acquisition Properties will manage all of the Properties.

The Company was founded in 1947 by John B. Kilroy, Sr., a nationally
prominent member of the real estate community, and is led by John B. Kilroy,
Jr., the Company's President since 1981. The Company's executive officers have
been with the Company for an average of approximately 13 years. The Company
has been involved in the ownership, acquisition, entitlement, development,
leasing and management of commercial properties, the majority of which are
located in Southern California, for nearly 50 years and has been focusing
primarily on office and industrial development for the past 30 years. The
Company presently has 47 employees, 34 of whom are located at the Company's
headquarters at Kilroy Airport Center at El Segundo, California.

The Company's strategy has been to own, develop, acquire, lease and manage
Class A properties in select locations in key suburban submarkets, primarily
in Southern California, that the Company believes have strategic advantages
compared to neighboring submarkets. The Company's extensive experience and
long-term presence in Southern California have enabled it to form key
alliances and working relationships with major corporate tenants,
municipalities and landowners in Southern California that have resulted in a
variety of development projects and provide an on-going source of development
and acquisition opportunities. The Southern California Properties located in
Los Angeles and Orange Counties are situated in locations which the Company
believes are among the best within key submarkets, offering tenants: (i) lower
business taxes and operating expenses than adjoining submarkets; (ii) access
to highly skilled labor markets; (iii) access to major transportation
facilities such as freeways, airports and the expanded Southern California
light-rail system; (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 airline travelers.

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
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, the Industrial Properties continue to serve the evolving needs of
their tenants, some of which have recently invested substantially in long-term
tenant improvements. As a result of the high quality and strategic location of
the Properties, and the Company's attention to the highest quality management
and service, the Company believes that the Properties attract major corporate
tenants and historically have achieved among the highest occupancy, tenant
retention and rental rates,

45
<PAGE>

both within their respective submarkets and as compared to their respective
neighboring submarkets. 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. 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 Los Angeles International
Airport. A second infrastructure 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. See "Business and Properties--
The Company's Southern California Submarkets--El Segundo Submarket."

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, as well as CompuServe, Inc., Employer's Health Insurance Co.,
the Federal Aviation Administration, First Nationwide Mortgage Corporation,
Furon Co., Inc., GTE Directories Sales Corporation, Great Western Bank,
HealthNet, Mattel, Inc. (which has its worldwide corporate headquarters in
El Segundo), North American Title Company, Northwest Airlines, Inc., Olympus
America, Inc., The Prudential Insurance Company of America, R.L. Polk &
Company, SCAN HealthPlan, Senn-Delaney Leadership Consulting Group, Inc.,
Transamerica Financial Services, Inc., 20th Century Industries, UniCare
Financial Corporation and Unihealth. As of December 31, 1995, the Company's
ten largest office tenants and ten largest industrial tenants (based upon
annual base rents as of December 31, 1995) had leased office space from the
Company for an average of 5.3 years. The Company's strong relationships with
its tenants is further evidenced by its average tenant retention rate (based
upon rentable square feet) for the period beginning January 1, 1994 and ending
September 30, 1996, which was 71.7% for the Properties located in the Southern
California Area and 50.9% for the Properties overall. The lower overall
retention rate results primarily from the 1993 termination of a lease,
scheduled to expire in 1995, for 211,000 net rentable square feet at the
SeaTac Office Center. The Company's extensive experience and long-term
presence in Southern California have enabled it to form key alliances and
working relationships with large corporate tenants, municipalities and
landowners that have led to a variety of development projects and provide a
continuing source of development and acquisition opportunities with
institutional sellers. As a result of its experience and relationships, the
Company currently has exclusive rights to develop approximately 24 acres of
developable land (net of the acreage required for streets) at Kilroy Airport
Center Long Beach. These properties are presently entitled for over
900,000 rentable square feet of office, industrial and retail space.

expire during such period; and (iii) the acquisition of strategic properties
with Units and/or with available cash and borrowings under the proposed Credit
Facility and its approximately $76 million of working capital cash reserves,
upon consummation of the Offering. In the second 12-month period following
consummation of the Offering, the Company expects sources of potential growth
in cash flow per share from: (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
planned development activities. In addition, the Company presently plans to
expand one or more of its Industrial Properties during the next two years,
subject to substantial pre-leasing. There can be no assurance, however, that
the Company will achieve any growth in cash available for distribution per
share, that available space will be leased, that leases scheduled to expire
will be renewed, that the Company will successfully complete any of its
planned development activities or that the Company will be able to acquire and
develop any of the Development Properties or other properties that may become
available. See "Risk Factors--Real Estate Investment Considerations--Risks of
Real Estate Acquisition and Development."

The Company will continue its practice of managing or administering
substantially all leasing, management, tenant improvements and construction on
an "in-house" basis and will be self-administered and self-managed. The
Company intends to elect to qualify as a REIT for federal income tax purposes
beginning with its taxable year ending December 31, 1997. See "Federal Income
Tax Consequences--Taxation of the Company."

GROWTH STRATEGIES

The Company's objectives are to maximize growth in cash flow per share 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 flow per share: (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 as
vacancy rates in the Company's submarkets generally continue to decline; (iv)
by developing properties for the benefit of the Company where such development
will result in a favorable risk-adjusted return on investment; and (v) by
expanding Properties within the Company's existing industrial portfolio. The
Company's ability to achieve its growth strategy will be aided by its working
capital cash reserves of approximately $76 million upon consummation of the
Offering and the proposed Credit Facility.

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
the 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 distressed sellers and inadvertent owners (through foreclosure or
otherwise) of office and industrial properties in the Company's markets, as
well as the Company's ability to acquire properties with Units (thereby
deferring the seller's taxable gain), all of which create enhanced acquisition
opportunities; (iii) the quality and location of the Properties; (iv) the
Company's access to development opportunities as a result of its significant
relationships with large Southern California corporate tenants, municipalities
and landowners and its nearly 50-year presence in the Southern California
market; and (v) the limited availability to competitors of capital for
financing development, acquisitions or capital improvements. Management
believes that the Company is well positioned to exploit existing opportunities
because of its extensive experience in its submarkets, its seasoned management
team and its proven ability to develop, lease and efficiently manage office
and industrial properties. In addition, the Company believes that public
ownership and its 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."

47
<PAGE>

Operating Strategies. The Company will focus on enhancing growth in cash
flow per share by: (i) maximizing cash flow from existing 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
September 30, 1996, the Company leased or renewed leases for an aggregate of
approximately 1.0 million rentable square feet of office space and
approximately 718,000 rentable square feet of industrial space. As of December
31, 1995, the Office Properties in the Southern California Area were
approximately 89.5% leased as compared to approximately 82.0% for the Southern
California Area, approximately 89.2% for the El Segundo submarket and
approximately 85.4% in the Long Beach submarket. In addition, at December 31,
1995, the Industrial Properties were approximately 91.4% leased as compared to
approximately 82.3% and approximately 87.1% for industrial properties located
in Los Angeles and Orange Counties, respectively. As of September 30, 1996,
(i) the Office Properties contained approximately 2.0 million rentable square
feet and were approximately 79.8% leased, and (ii) the Industrial Properties
contained an aggregate of approximately 1.3 million rentable square feet and
were approximately 93.7% leased. In addition, the number of individual lease
transactions since 1992, including the results for the nine-month period ended
September 30, 1996, averaged over 33 per year. See "Business and Properties--
General," "--Properties," "--Occupancy and Rental Information," and "--The
Company's Southern California Submarkets."

Approximately 1.0 million aggregate rentable square feet in the Properties
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,
approximately 66.5% of the Company's net 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 December 31, 1996 approximately 36.7% of the
Company's total base rent (representing approximately 23.7% of the aggregate
net rentable square feet of the Properties) was attributable to leases with
Consumer Price Index increases and approximately 28.1% of the Company's total
base rent (representing approximately 30.5% of the aggregate net rentable
square feet of the Properties) is 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
future economic conditions will support higher rental rates. See "Risk
Factors--Real Estate Investment Considerations."

in the market which lack its access to capital or the ability to issue Units.
See "Business and Properties-- Development, Leasing and Management
Activities."

The Company has entered into an agreement to acquire the two office
properties that comprise Phase I of Kilroy Airport Center Long Beach. Kilroy
Airport Center Long Beach Phase I was developed by the Company in 1987 and has
been leased and managed by the Company since its inception. In addition, the
Company has entered into an agreement to purchase an office property located
in Thousand Oaks, California. The Company also has entered into an agreement
to acquire a three building office and industrial complex located in Anaheim,
California. Furthermore, KI, on behalf of the Operating Partnership, has
acquired a multi-tenant industrial property located in Garden Grove,
California. The acquisition of the Acquisition Properties by the Company is
expected to occur concurrently with the consummation of the Offering and,
accordingly, the Acquisition Properties are included in the discussion of the
Properties included throughout this Prospectus. There can be no assurance,
however, that the Company will be able to complete any property acquisitions,
including the acquisition of the Acquisition Properties, successfully develop
any land acquired or improve the operating results of any developed properties
that are acquired. See "Business and Properties--Acquisition Properties."

Development Strategies. The Company's interests in the Development
Properties provide it with significant growth opportunities.

The Company is the master ground lessee of, and has sole development rights
in, Kilroy Airport Center Long Beach, a planned four-phase, approximately 53-
acre property entitled for office, research and development, light industrial
and other commercial projects at which the Company will own, upon consummation
of the Offering, all five existing Office Properties and manages all ongoing
leasing and development activities. The Company developed Phases I and II in
1987 and 1989/1990, respectively, encompassing an aggregate of approximately
620,000 rentable square feet of office and light industrial space. The Company
controls development of the Phase III and IV parcels while receiving rental
revenue in connection with such parcels under current leases expiring in July
2009 and September 1998, respectively, in amounts sufficient to cover a
substantial portion of the predevelopment carrying costs. Phases III and IV
presently are planned to be developed on the project's approximately
24 undeveloped acres and are entitled for an aggregate of approximately
900,000 rentable square feet. The Company is currently in discussions with
several prospective tenants for office space presently planned to be included
in Kilroy Long Beach Phase III. Development of each of Phases III and IV is
subject to substantial predevelopment leasing activity and, therefore, the
timing for the commencement of development of Phases III and IV is uncertain.
No assurance can be given that the Company will commence such development when
planned, or that, if commenced, 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 Long Beach."

not limit the amount of indebtedness that the Company may incur. Upon
completion of the transactions outlined under the caption "Formation and
Structure of the Company," total debt will constitute approximately 21.5% of
the total market capitalization of the Company. In addition, upon consummation
of the Offering, the Company will have working capital cash reserves of
approximately $76 million. The Company anticipates that upon consummation of
the Offering all but approximately $12.0 million of the permanent indebtedness
will bear interest at fixed rates. The Company intends to utilize one or more
sources of capital for future acquisitions, including development and capital
improvements, which may include undistributed cash flow, borrowings under the
proposed Credit Facility, the Company's approximately $76 million of working
capital cash reserves 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 "--Growth Strategies," "The Company--Growth
Strategies" and "Business and Properties--Development, Leasing and Management
Activities."

USE OF PROCEEDS

The net proceeds to the Company from the sale of Common Stock in the
Offering, after deduction of underwriting discounts and commissions, advisory
fees and estimated offering expenses, are expected to be approximately $262.9
million (approximately $303.0 million if the Underwriters' over-allotment
option is exercised in full). In addition to the net proceeds from the
Offering, the Operating Partnership expects to receive net proceeds from the
Mortgage Loans, after payment of expenses related thereto, of approximately
$95.4 million. The Company intends to apply the net proceeds of the Offering
and from the Mortgage Loans as follows:

million (including accrued interest and loan fees), of which approximately
$37.2 million has been guaranteed by certain members of the Kilroy Group,
including officers and directors of the Company. An aggregate of approximately
$32.1 million of indebtedness was incurred within the last year, of which $1.5
million was incurred to finance tenant improvements and to pay leasing
commissions related to Kilroy Airport Center Long Beach, $9.1 million was
incurred by KI (on behalf of the Company) to acquire the Industrial Property
located at 12752-12822 Monarch Street, Garden Grove, California (including
expenses at closing) and $21.5 million was used to repay $16.6 million of
existing indebtedness (including $3.4 million of indebtedness of John B.
Kilroy, Sr., the Chairman of the Company's Board of Directors, and accrued
interest and prepayment penalties in connection with such repayments), and to
pay approximately $940,000 in property taxes and approximately $454,000 in
loan costs, legal fees and other expenses in connection with such financing,
with the remainder being contributed to working capital.

The approximately $49.0 million to be used to purchase the Acquisition
Properties referenced above represents the aggregate purchase price paid or to
be paid (including expenses at closing) pursuant to executed agreements for
the acquisition of Kilroy Airport Center Long Beach Phase I, the Westlake
Office Plaza and the Anaheim Office and Industrial Properties. The acquisition
of the Industrial Property located at 12752-12822 Monarch Street, Garden
Grove, California is reflected in the repayment of existing mortgage debt (net
of discounts/premiums) referenced above, as this amount was incurred by KI on
behalf of the Company to acquire the property prior to consummation of the
Offering based on the closing schedule required by the seller. See "Business
and Properties--Acquisition Properties."

In addition, the Company presently intends to use the approximately $2.5
million of capital expenditure cash reserves to pay to Hughes Space &
Communications, in connection with Formation Transactions, the remaining
balance of approximately $1.4 million in connection with the amendment and/or
extension of leases of office space at the Office Properties located at Kilroy
Airport Center, including $500,000 in connection with a tenant improvement
allowance for the properties located at 2240 and 2250 E. Imperial Highway and
the balance in connection with the cancellation of an option to purchase an
equity interest in the Office Properties located at Kilroy Airport Center at
El Segundo. Also from such $2.5 million capital expenditure cash reserves, in
connection with the Financing, the Company will make earthquake-related
improvements to certain of the Properties in an aggregate net amount of
approximately $600,000. The improvements and repairs reserve required in
connection with the Financing is expected to be funded out of the working
capital cash reserves. See "The Financing--The Mortgage Loans."

The following table presents the balances, as of September 30, 1996, and the
expected balances as of the date the Offering is consummated, of the mortgages
and loans (which are all of the current outstanding mortgages and loans on the
Properties) intended to be repaid out of the net proceeds of the Offering. The
mortgages expected to be repaid upon completion of the Offering had a weighted
average interest rate of approximately 8.74% and a weighted average remaining
term to maturity of approximately 3.14 years as of September 30, 1996.

(3) This indebtedness is also secured by a second mortgage on the properties
located at 1000 East Ball Road, Anaheim, California, 1230 S. Lewis Street,
Anaheim, California and 2031 E. Mariposa Avenue, El Segundo, California.

(4) Represents the principal amount of indebtedness incurred on December 19,
1996, by KI on behalf of the Company, in connection with the acquisition
of the Industrial Property located at 12752-12822 Monarch Street, Garden
Grove, California, plus accrual of related closing expenses. See "Business
and Properties--Acquisition Properties--12752-12822 Monarch Street, Garden
Grove, California." The indebtedness matures on the earlier of the date on
which the Offering is consummated and June 20, 1997 and, as of December
31, 1996, had an interest rate of approximately 8.41%.

In the event that the Underwriters' over-allotment option is exercised, the
net proceeds thereof will be used by the Company for additional working
capital and will be available for development and for future acquisitions of
additional properties not yet identified. Pending 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.

DISTRIBUTION POLICY

The Company presently intends to make regular quarterly distributions to
holders of its Common Stock. The first distribution, for the period commencing
upon the consummation of the Offering and ending March 31, 1997, is
anticipated to be approximately $.2583 per share (which is equivalent to a
quarterly distribution of $.3875 per share or an annual distribution of $1.55
per share) which results in an initial annual distribution rate of 6.74%. The
Company does not expect to change its estimated distribution rate if any of
the Underwriters' over-allotment option is exercised. The Company currently
expects to distribute approximately 90.7% of estimated cash available for
distribution for the 12 months following the consummation of the Offering.
Units and shares of Common Stock will receive equal distributions. The Board
of Directors may vary the percentage of cash available for distribution which
is distributed if the actual results of operations, economic conditions or
other factors differ from the assumptions used in the Company's estimates.

The Company believes that its estimate of cash available for distribution
constitutes a reasonable basis for setting the initial distribution rate and
is made solely for the purpose of setting the initial distribution rate and is
not intended to be a projection or forecast of the Company's results of
operations or of its liquidity. The Company presently intends to maintain the
initial distribution rate for the 12 months following the consummation of the
Offering unless actual results from operations, economic conditions or other
factors differ significantly from the assumptions used in its estimate.
However, no assurance can be given that the Company's estimate will prove
accurate. The actual return that the Company will realize will be affected by
a number of factors, including the revenue received from the Properties, the
distributions and other payments received from the Operating Partnership and
Services Company (which in turn is based in part on revenues received from
development activities), the operating expenses of the Company, the interest
expense incurred on its borrowings, the ability of tenants to meet their
obligations, general leasing activity and unanticipated capital expenditures.
See "Risk Factors--Real Estate Investment Considerations."

(1) The effect of including the Services Company was a reduction in Funds
from Operations of $50,000 during such period.
(2) Pro forma depreciation of $9,595,000 for the year ended December 31, 1995
plus $6,773,000 for the nine months ended September 30, 1996 less
$7,163,000 for the nine months ended September 30, 1995. Pro forma
amortization of $985,000 for the year ended December 31, 1995 plus
$895,000 for the nine months ended September 30, 1996 less $839,000 for
the nine months ended September 30, 1995. Amortization consists primarily
of amortization of deferred leasing commissions. Non-cash interest
expense of $75,000 for the year ended September 30, 1996 related to
amortization of the costs associated with the Mortgage Loans is not added
back in this table in conformity with NAREIT's definition of Funds from
Operations.
(3) Includes elimination of the cost to buy out an option held by a third
party to acquire a portion of a Property ($3,150,000) and compensation
expense relating to a restricted Common Stock grant ($460,000).
(4) Represents an incremental increase in Funds from Operations attributable
to contractual rental increases for the 12 months ending January 31, 1998
(over actual rental revenue included in pro forma Funds from Operations
for the 12 months ended September 30, 1996). The contractual rental
increases are limited to the actual number of months in which the
increased rental rate will be in effect as to each lease.

<PAGE>

(5) Represents the incremental increase in Funds from Operations attributable
to rental revenue from new executed leases commencing after September 30,
1995 for the 12 months ending January 31, 1998.

(6) Represents the elimination of rental revenue reflected in rental revenue
for the 12 months ended September 30, 1996 from: (i) leases which expired
between September 30, 1995 and September 30, 1996 ($1,249,000) and (ii)
leases which will expire between October 1, 1996 and January 31, 1998 for
that portion of the 12 months ending January 31, 1998 that such leases
are no longer in effect ($2,803,000).

This table assumes that leases which expire prior to January 31, 1998 will
not be renewed or re-leased during the period. As a result of this
assumption, the effective average occupancy rate of the Properties for the
12-month period ending January 31, 1998 will equal approximately 87.2%,
versus the actual occupancy rate for the Properties of approximately 88.2%
as of December 31, 1996. The Company's average tenant retention rate for
expiring leases for January 1, 1994 through September 30, 1996 was
approximately 71.7% for the Properties located in the Southern California
Area and 50.9% for the Properties overall.

(7) Represents the effect of adjusting straight-line rental income and
expense included in pro forma net income from an accrual basis under GAAP
to a cash basis.

(8) Represents estimated interest earned at 5% on working capital cash
reserves of $76,672,000.

(9) Reflects projected non-incremental revenue-generating tenant improvement
("TI") and leasing commission ("LC") for the 12-month period ending
January 31, 1998 based on the weighted average TI and LC expenditures for
all renewed and retenanted space incurred during 1993, 1994, 1995 and the
nine months ended September 30, 1996, multiplied by the average annual
net rentable square feet of leased space expiring during the three 12-
month periods following the consummation of the Offering.

(i) The Company's historical weighted average renewal rate, based on net
rentable square footage, from January 1, 1994 through September 30,
1996 was 71.7% for the Properties located in the Southern California
Area and 50.9% for the Properties overall. The lower overall renewal
rate results primarily from a 1993 termination of a lease, scheduled
to expire in 1995, for 211,000 square feet at the SeaTac Office
Center. Management believes, based on historical figures and its
review of market conditions in the Company's submarkets in which the
Properties are located, that the assumption of a 70% renewal rate is
reasonable.

(10) Estimated annual capital expenditures not reimbursed by tenants. The
average of historical nonreimbursed capital expenditures at the Office
and Industrial Properties during the years ended December 31, 1994 and
1995 was $150,000. All capital expenditures during 1993 were reimbursed
by tenants.

(11) Estimated principal payments on the Mortgage Loans. Excludes the net
effect of the refinancing of the SeaTac Loan.

(12) The Company's share of estimated distributions based on its approximately
82.6% partnership interest in the Operating Partnership.

(13) Calculated as the estimated initial annual distribution divided by the
estimated cash flow available for distribution for the 12 months ending
January 31, 1998. The payout ratio of estimated adjusted pro forma Funds
from Operations (which is substantially equivalent to the Company's
estimated pro forma cash flow from operating activities) for the 12
months ending January 31, 1998 equals 82.8%.

The Company anticipates that its estimated 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. Based on the estimated cash flow available for
distribution set forth in the table above, the Company believes that
approximately 10% of distributions for the 12 months following consummation of
the Offering would represent a return of capital. 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 U.S. Stockholders"
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.

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 will seek 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 will be subject to the requirements of
the MGCL and the discretion of the Board of Directors of the Company, and will
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" and "--Distribution Payout Percentage." 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.

56
<PAGE>

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.

Cash available for distribution is based on Funds from Operations (which is
defined by NAREIT as net income (loss) (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 after adjustments for unconsolidated
partnerships and joint ventures. The calculation of adjustments to pro forma
Funds from Operations is being made solely for the purpose of setting the
initial distribution amount and is not intended to be a projection or
prediction of the Company's actual results of operations nor is the
methodology upon which such adjustments are made intended to be a basis for
determining future distributions. 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 "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Funds from Operations."

The Company intends to provide 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 Commission rules and regulations.

DILUTION

Purchasers of the Common Stock offered hereby will experience an immediate
and substantial dilution of the net tangible book value of their Common Stock
from the initial public offering price. At September 30, 1996, the Company had
a negative combined net tangible book value of approximately $113.2 million,
or negative $42.69 per share of Common Stock (assuming the exchange of Units
issued to Continuing Investors in connection with the Formation Transactions
into shares of Common Stock on a one-for-one basis). After giving effect to
the sale of the shares of Common Stock offered hereby at the initial public
offering price of $23.00 per share of Common Stock, the deduction of
underwriting discounts and commissions, advisory fees and estimated Offering
expenses and the receipt by the Company of approximately $262.9 million in net
proceeds from the Offering, the pro forma net tangible book value at September
30, 1996 would have been $129.7 million, or $10.29 per share of Common Stock.
This amount represents an immediate increase in net tangible book value of
$52.98 per Unit to Continuing Investors and an immediate dilution in pro forma
net tangible book value of $12.71 per share of Common Stock to new public
investors. The following table illustrates this per share dilution:

(1) Net tangible book value per share of Common Stock before the Offering is
determined by dividing net tangible book value (total tangible assets less
total liabilities) of the Company by the number of shares of Common Stock
of the Company representing the exchange in full of the Units to be issued
to the Continuing Investors.
(2) Based on pro forma net tangible book value of approximately $129.7 million
divided by 12,600,000 shares of Common Stock outstanding. There is no
impact on dilution attributable to the exchange of Units to be issued to
the Continuing Investors due to the effect of minority interest.
(3) Dilution is determined by subtracting pro forma net tangible book value
per share of Common Stock after giving effect to the Formation
Transactions and the Offering from the initial public offering price paid
by a new investor for a share of Common Stock.

The following table sets forth, on a pro forma basis giving effect to the
Offering and the Formation Transactions: (i) the number of shares of Common
Stock to be sold by the Company in the Offering and the number of Units issued
to the Continuing Investors in connection with the Formation Transactions;
(ii) the net tangible book value as of September 30, 1996 of the assets
contributed to the Operating Partnership in the Formation Transactions; and
(iii) the net tangible book value of the average contribution per share/Unit
based on total contributions. See "Risk Factors--Immediate and Substantial
Dilution."

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

(2) As defined by the National Association of Real Estate Investment Trusts
("NAREIT"), Funds from Operations represents net income (loss) before
minority interest of unit holders (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 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 1996 and 1995, 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 notes
(9), (10) and (11) under the caption "Distribution Policy" and 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.

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 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 other than the Acquisition Properties. As part
of the Formation Transactions, the Properties will be contributed to the
Operating Partnership, of which the Company will be the sole general partner
and the beneficial owner of an approximately 82.6% interest. As a result, for
accounting purposes, the financial information of the Operating Partnership
and the Company will be consolidated.

RESULTS OF OPERATIONS

Nine Months Ended September 30, 1996 Compared to Nine Months Ended September
30, 1995

Total revenues decreased $3.5 million, or 10.6%, for the nine months ended
September 30, 1996 compared to the same period for 1995. Revenues from base
rents increased $1.1 million, or 4.6%, to $25.2 million in the 1996 period
compared to $24.1 million in the 1995 period. Rents from Office Properties
increased $0.8 million during the nine months ended September 30, 1996 from
the comparable period in 1995. Such increase was due to office space under
lease increasing from 1,229,000 square feet at September 30, 1995 to 1,288,000
square feet at September 30, 1996. The majority of this increase relates to
leasing at Kilroy Airport Center Long Beach. There was no significant change
in rent per square foot during the 1996 period compared to the 1995 period.
Rents from Industrial Properties increased a net $0.3 million during the nine
months ended September 30, 1996 compared to the same period in 1995. The net
increase was due to a lease with a Consumer Price Index ("CPI") increase and
the effect of the 2260 E. El Segundo Boulevard Building being leased for the
entire nine months ended September 30, 1996. Tenant reimbursements and parking
revenues increased to $2.6 million and $1.3 million, respectively, in the 1996
period compared to $2.4 million and $1.2 million for the same period in 1995.
The overall $0.3 million increase is primarily due to increased billable
operating expenses resulting from new leases and parking income. 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 nine months ended September 30, 1996 increased by $0.4
million, or 1.1%, to $35.0 million compared to $34.6 million in the 1995
period. During the nine months ended September 30, 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 interest in Kilroy Airport Center at El
Segundo. Interest expense decreased $2.5 million, or 13.4%, to $16.2 million
in 1996 from $18.7 million in 1995, primarily as a result of the forgiveness
and restructuring of certain debt in 1995 and 1996 (see Note 4 to the Combined
Financial Statements).

Net income was $14.8 million for the nine months ended September 30, 1996
compared to $13.9 million for the same period in 1995. The increase of $0.9
million is due primarily to a decrease in interest expense of $2.5 million, an
increase in extraordinary gains of $4.8 million less the nonrecurring option
buy-out cost of $3.15 million for the 1996 period and the sale of air rights
of $4.5 million in 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. Revenues from base
rents increased $1.1 million, or 3.5%, to $32.3 million in 1995 from $31.2
million in 1994. In 1995, rents from Industrial Properties 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 1994. Office square footage and average
rent per net 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 a year earlier. 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

62
<PAGE>

at a rate of $6.11 per net rentable square foot, down from the rate of $6.43
in effect for the prior year. Tenant reimbursements increased to $3.0 million
in 1995 from $1.6 million in 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 in 1994 due to recognition of 12-
months' parking income for Kilroy Airport Center Long Beach in 1995 compared
to two months in 1994, together with increased tenant parking revenues at
Kilroy Airport Center at El Segundo. Revenues for 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 1995 compared to 1994, primarily as a
result of nonrecurring interest income of $0.4 million on the property tax
refunds referred to below.

Expenses in 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 in 1994,
primarily due to the $2.4 million property tax refund recorded by the Company
in 1994 and the effect of a reduction in aggregate assessed property values in
1995. General and administrative expenses decreased $0.3 million, or 12.0%, to
$2.2 million in 1995 from $2.5 million in the 1994 period, primarily due to a
$0.3 million penalty for late payment of property taxes in 1994. Interest
expense decreased $1.2 million to $24.2 million in 1995 from $25.4 million in
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 in 1995, reflecting the effect of 12 months' reduction of ground
rent for Phase III of Kilroy Airport Center Long Beach compared to six months
in 1994. The $0.5 million decrease in depreciation and amortization to
$9.5 million in 1995 results from certain assets becoming fully amortized.

Net income increased $19.3 million to $12.6 million in 1995 compared to a
net loss of $6.7 million in 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 in 1995 compared to $1.8 million in 1994.

Year Ended December 31, 1994 Compared to Year Ended December 31, 1993

Total revenues decreased $10.4 million, or 22.3%, for the year ended
December 31, 1994 compared to the year ended December 31, 1993. The primary
reason for the decrease in revenue was the receipt of lease termination fees
in 1993 of $5.2 million, of which $5.0 million related to a lease termination
at the SeaTac Office Center and $0.2 million to the Kilroy Airport Center Long
Beach. Revenues from base rents decreased $3.0 million, or 8.8%, to $31.2
million for the year ended December 31, 1994 compared to $34.2 million for the
year ended December 31, 1993, due to the lease termination at the SeaTac
Office Center referred to above (with $2.0 million in rental revenue in 1993),
a lease renegotiation resulting in a lower rent rate effective June 1, 1994
for a lease on office space in the parking structure at Kilroy Airport Center
at El Segundo, partially offset by continuing leasing activity at Kilroy
Airport Center Long Beach. Office square footage under lease decreased to
1,239,000 at December 31, 1994 from 1,360,000 at December 31, 1993. The
decrease is due primarily to the termination of the lease at the SeaTac Office
Center (211,000 square feet) offset by 30,000 square feet of new leases
elsewhere in the project and a 55,000 increase in square footage leased at
Kilroy Airport Center Long Beach. Average office rent per square foot declined
$2.33 per square foot in 1994 from 1993 due to the lease renegotiation
referred to above and a softness in the Southern California rental market in
1994. Industrial rents decreased $0.2 million in 1994 primarily due to an
extension of a lease at a reduced rate.

Tenant reimbursements decreased to $1.6 million in 1994 from $4.9 million in
1993, due to a $1.5 million refund to tenants in 1994 for property tax refunds
(for the tax years 1990 through 1994) and an approximate $1.5 million decrease
due to the termination of the SeaTac Office Center lease referred to above.
Tenant reimbursements consist of additional rental revenue from tenants
covering operating expenses, such as utilities and property taxes, and are
recorded as revenue in accordance with the lease terms. Other income increased
$0.6 million, to $0.8 million in 1994 from $0.2 million in 1993, primarily as
a result of interest income of $0.4 million on the property tax refunds
referred to above.

63
<PAGE>

Expenses in 1994 decreased $4.0 million, or 8.2%, to $44.7 million compared
to $48.7 million in 1993. Property expenses decreased $0.4 million, or 6.1%,
due to the vacancy at SeaTac Office Center referred to above and the related
reduction in expenses. Real estate taxes decreased $3.4 million to a credit
balance of $0.4 million in 1994 from taxes of $3.0 million in 1993, primarily
due to property tax refunds of $2.4 million (for the tax years 1990 through
1994) recorded by the Company in 1994 together with an approximate $1.0
million decrease resulting from a reduction in aggregate assessed value of the
Properties during the year ended December 31, 1994. General and administrative
expenses increased $1.4 million, to $2.5 million in 1994 from $1.1 million in
1993, principally due to a $0.6 million increase in the allowance for
uncollectible rent attributable to a single tenant, a $0.3 million penalty in
1994 for late payment of property taxes and $0.2 million of expenses relating
to a financing arrangement which was not consummated. Interest expense
decreased $0.4 million, to $25.4 million in 1994 due to a decrease in the
interest rate on the variable rate mortgage secured by Kilroy Airport Center
Long Beach. Depreciation and amortization decreased $0.9 million to $10.0
million in 1994 as a result of certain assets becoming fully amortized.

The net loss increased $4.6 million to $6.7 million in 1994 compared to a
net loss of $2.1 million in 1993, due to lease termination fees of $5.2
million received in 1993 and the net effect of the items discussed above.

</TABLE>

Subsequent to the Formation Transactions, the Company's and the Kilroy
Group's development activities will be conducted through Kilroy Services,
Inc., See "Formation and Structure of the Company--Formation Transactions" and
"Formation of Kilroy Services, Inc."

The increases in revenues in 1994, as compared with 1993, and in 1995, as
compared with 1994, was a result of the commencement of development services
for the Riverside Judicial Center (commencing in 1994) and the Northrop
Grumman Corporation's property located in Pico Rivera, California (the
agreement for which commenced in 1995 and expires in February 1997). The $0.3
million decrease in revenues during the nine months ended September 30, 1996
compared with the same period in 1995 was primarily the result of a decrease
in development services at the Calabasas Park Centre which was acquired by the
stockholders of KI in 1996. Revenues from Calabasas Park Centre were $0.1
million, $0.4 million, $0.5 million, $0.7 million and $0.7 million for the
nine months ended September 30, 1996 and 1995 and the years ended December 31,
1995, 1994 and 1993, respectively. The remainder of the decrease was due to
the substantial completion of development services for the Riverside Judicial
Center. A portion of the related expenses of development and management
services are fixed in nature and have not fluctuated significantly, while the
majority of the related expenses are variable in nature and fluctuate with the
level of development and management activities. With the acquisition of
Calabasas Park Centre by the Kilroy Group in 1996, and completion of the fee
activities pursuant to the agreement with Northrop Grumman in February 1997,
the Company does not expect significant fee activity from these sources.

ADOPTION OF SFAS NO. 121

<PAGE>

LIQUIDITY AND CAPITAL RESOURCES

Upon the consummation of the Offering and the Formation Transactions and the
use of proceeds therefrom, the Company will have (i) acquired the Acquisition
Properties, (ii) reduced its total indebtedness by approximately $128.0
million and (iii) established working capital cash reserves of approximately
$76 million and capital expenditure cash reserves of approximately $2.5
million. The Company is currently negotiating a $100.0 million Credit
Facility, which the Company expects to enter into shortly after consummation
of the Offering. The Credit Facility is expected to be used primarily to
finance acquisitions of additional properties. The availability of funds under
the Credit Facility is expected to be subject to, among other things, the
value of the underlying collateral securing it. The Company expects that,
initially, it will have approximately $50.0 million in availability under the
Credit Facility. In connection with certain leases signed after September 30,
1996, the Company is obligated to fund approximately $2.0 million in tenant
improvements and leasing commissions. This obligation will be assumed by the
principals of KI. The Company presently expects to finance development
activities from working capital and from funds from operations. See "The
Financing--The Credit Facility." In addition, if the Offering is consummated
on or before June 30, 1997, the Company will pay to Richard E. Moran Jr., the
Company's Executive Vice President, Chief Financial Officer and Secretary, a
bonus of $200,000, pursuant to the terms of his employment agreement. This
obligation also will be assumed by the principals of KI. See "Management--
Executive Compensation."

The Company anticipates that distributions will be paid from cash available
for distribution, which is expected to exceed cash historically available for
distribution as a result of the reduction in debt service anticipated to
result from the repayment of indebtedness. The Company presently intends to
make distributions quarterly, subject to the discretion of the Board of
Directors. Amounts accumulated for distribution will be 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.

The Company believes the Offering and the Formation Transactions will
improve its financial performance through changes to its capital structure,
principally the substantial reduction in its overall debt and its debt to
equity ratio. Through the Formation Transactions, the Company will repay all
of its existing mortgage debt of $224.0 million secured by the Properties
(other than the Acquisition Properties) and will have debt outstanding of
$96.0 million comprised of the $84.0 Million Loan and the $12.0 million SeaTac
Loan. The $84.0 Million Loan amortizes over 25 years and matures in 2005. The
SeaTac Loan matures in July 1997. Thus, total secured debt after the Formation
Transactions (assuming no advances under the Credit Facility) will be reduced
by approximately $128.0 million. This will result in a significant reduction
in annual mortgage interest expense as a percentage of total revenue (15.9% on
a pro forma basis as compared to 56.3% for the historical year ended December
31, 1995). Cash from operations required to fund interest expense will
decrease substantially, although this reduction will be offset by the use of
cash from operations to meet annual REIT distribution requirements. The market
capitalization of the Company, based on the initial public offering price of
$23.00 per share and the debt outstanding at the completion of the Offering,
is expected to be approximately $446.8 million with total debt of
approximately $96.0 million. As a result, the Company's debt to total market
capitalization ratio will be approximately 21.5%.

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
$0.2 million, $0.5 million and $0.6 million were past due as of September 30,
1996, and December 31, 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 has

65
<PAGE>

continued and a note payable to an insurance company having a principal
balance of $20.2 million and accrued interest of $1.9 million, as of September
30, 1996, has been in default since October 1995. In October 1996, the Company
successfully negotiated a discounted payoff with the lender and the ground
lessor which provides for a payoff or purchase of the lender's note at a
discount on or before February 10, 1997. The Company believes it will be able
to meet this commitment irrespective of the consummation of the Offering based
upon discussions with other sources of financing. 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 expects to meet its short-term liquidity requirements generally
through its initial working capital, net cash provided by operations and
additional debt or equity financings. The Company estimates that for the 12
months ending September 30, 1997 it will incur approximately $1.1 million of
expenses attributable to non-incremental revenue generating tenant
improvements and leasing commissions and $310,000 of capital expenditures not
reimbursed by tenants. The Company expects that it will incur tenant
improvement and leasing commission costs in connection with the leasing-up of
available space at the SeaTac Office Center. Based upon current market
conditions, the Company estimates that such tenant improvements will be
approximately $15.00 to $20.00 per net rentable square foot and leasing
commissions will be approximately 6.0% to 7.0% of total lease payments made
during the first four years of the lease term, and approximately 3.0% to 4.0%
of total lease payments thereafter. As of December 31, 1996, approximately
330,000 net rentable square feet were available for lease at the SeaTac Office
Center. In addition, the Company will set aside approximately $2.7 million of
the net proceeds of the Offering for certain nonrecurring capital
expenditures. See "Distribution Policy." From such $2.7 million capital
expenditure cash reserves, the Company will pay to Hughes Space &
Communications, in connection with Formation Transactions, the remaining
balance of approximately $1.4 million in connection with the amendment and/or
extension of leases of office space at the Office Properties located at Kilroy
Airport Center, including $500,000 in connection with a tenant improvement
allowance for the properties located at 2240 and 2250 E. Imperial Highway and
the balance in connection with the cancellation of an option to purchase an
equity interest in the Office Properties located at Kilroy Airport Center at
El Segundo. In November 1996, $2.26 million of the option buy-out liability
was paid by KI and its stockholders. Also from such $2.7 million capital
expenditure cash reserves, in connection with the Financing, the Company will
make earthquake-related improvements to certain of the Properties in an
aggregate amount of approximately $600,000. The Company presently has no
financial commitments in its capacity as a developer of real estate projects
and believes that it will have sufficient capital resources to satisfy its
obligations during the 12-month period following completion of the Offering,
and that its net cash provided by operations will be adequate to meet both
operating requirements and expected distributions by the Company in accordance
with REIT requirements.

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 $12.0 million in July
1997 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 extraordinary
items in each of the last five years and for the nine-month period ended
September 30, 1996.

66
<PAGE>

However, after adding back depreciation and amortization, the Properties have
generated positive net operating cash flows for the last four years.

The Company's net cash provided by operating activities decreased to $6.6
million for the year ended December 31, 1994 from $11.5 million for the same
period in 1993 primarily as a result of lease termination fees of $5.2
received in 1993. 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. The
Company's net cash from operating activities decreased $3.8 million to $5.5
million during the nine months ended September 30, 1996 compared with $9.3
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 $1.3 million in 1996
and a decrease in interest expense of $2.5 million in 1996.

Net cash received from investing activities of $2.0 million for the year
ended December 31, 1993 decreased to net cash used in investing activities of
$1.8 million for the same period in 1994 due to the receipt in the 1993 period
of a $2.7 million reimbursement 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. Net cash used in investing activities increased $1.7 million to
$2.1 million in the nine months ended September 30, 1996 from $0.4 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.

The Company's cash flows used in financing activities decreased $8.7 million
to $4.8 million from $13.5 million for the year ended December 31, 1993 as a
result of net borrowings of $3.9 million during the year ended December 31,
1994 compared to a net repayment of $2.7 million of debt in the 1993 period,
together with an decrease in deemed distributions to partners to $8.7 million
during the year ended December 31, 1994 compared to $10.7 million in the 1993
period. 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 repayments 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.
Cash flows used in financing activities was $3.4 million for the nine months
ended September 30, 1996 consisting of net proceeds from issuance of debt of
$2.8 million, less $6.2 million in 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) determined in
accordance with GAAP, excluding gains (or losses) from debt restructuring and
sales of property, plus depreciation and amortization (other than 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.

BUSINESS AND PROPERTIES

GENERAL

Upon the consummation of the Offering and the Formation Transactions, the
Company (through the Operating Partnership) will own 14 Office Properties
encompassing an aggregate of approximately 2.0 million rentable square feet
and 12 Industrial Properties encompassing an aggregate of approximately
1.3 million rentable square feet. Eleven of the 14 of the Office Properties as
well as 11 of the 12 Industrial Properties are located in prime Southern
California suburban submarkets (including a complex of three Office Properties
located adjacent to the Los Angeles International Airport, presently the
nation's second largest air cargo port, and a complex of five Office
Properties located adjacent to the Long Beach Municipal Airport). The Company
also will own three Office Properties located adjacent to the Seattle-Tacoma
International Airport in the State of Washington, and one Industrial Property
located in Phoenix, Arizona. As of September 30, 1996, the Office Properties
were approximately 79.8% leased to 130 tenants and the Industrial Properties
were approximately 93.7% leased to 20 tenants. The Company has developed,
managed and leased all but two of the 14 Office Properties and all but five of
the 12 Industrial Properties. The Company believes that all of its Properties
are well-maintained and, based on recent engineering reports, do not require
significant capital improvements.

In addition to the Office and Industrial Properties, the Company has
development rights with respect to approximately 24 acres of developable land
(net of acreage required for streets), located in Southern California. See "--
Development, Leasing and Management Activities." Upon consummation of the
Offering, the Company also will have the option to purchase three office
properties and 18 acres of undeveloped land currently beneficially owned and
controlled by John B. Kilroy, Sr. and John B. Kilroy, Jr. which will not be
contributed to the Operating Partnership immediately upon consummation of the
Offering. The Company will have the right to acquire the option properties
under the terms and conditions described below. All of these properties will
be managed by the Company. See "--Excluded Properties."

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. All 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.

The following table sets forth certain information (on a per net rentable
square foot basis) regarding leasing activity at the Office Properties managed
by the Company (i.e., all of the Office Properties other than the Thousand
Oaks Office Property and the La Palma Business Center Office Property which
are being acquired concurrently upon consummation of the Offering) since
January 1, 1992 (based upon an average of all lease transactions during the
respective periods):

THE OFFICE AND INDUSTRIAL PROPERTIES

The following table sets forth certain information relating to each of the
Properties as of December 31, 1995, unless indicated otherwise. This table
gives pro forma effect to a recent extension of one of the leases with Hughes
Space & Communications with respect to two of the Office Properties located at
Kilroy Airport Center at El Segundo as if such lease renewal had occurred on
January 1, 1995. After completion of the Formation Transactions, the Company
(through the Operating Partnership) will own a 100% interest in all of the
Office and Industrial Properties other than the five Office Properties located
at Kilroy Airport Center Long Beach and the three Office Properties 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.

31, 1995.
(2) Total base rent for the year ended December 31, 1995, determined in
accordance with generally accepted accounting principles ("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 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.
(3) Aggregate base rent received over their respective terms from all leases
in effect at December 31, 1995 minus all tenant improvements, leasing
commissions and other concessions for all such leases, 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."
(4) Base rent for the year ended December 31, 1995 divided by net rentable
square feet leased at December 31, 1995.

leased at December 31, 1995.
(6) Based on all leases at the respective Properties dated on or before
September 30, 1996. Occupancy for all Properties at December 31, 1996 was
approximately 88.2%.

(8) For this Property, a lease 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.
(9) 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.
(10) For this Property, leases with Hughes Space & Communications for
approximately 101,000 rentable square feet are written on a full service
gross basis except that there is no Expense Stop.
(11) This Property is an Acquisition Property.
(12) For this Property, the lease is written on a triple net basis.
(13) This Industrial Property was vacant until April 1995. The tenant began
paying rent in mid-October 1995 at an annual rate of $4.40 per rentable
square foot.
(14) 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.
(15) This lease terminates on December 31, 1996.
(16) 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.
(17) The leases for this Industrial Property are written on a modified triple
net basis, with the tenants responsible for estimated allocated common
area expenses.

included on a contract basis.
(7) The term of this lease has been extended to 2007 and, effective February
1, 1997, annual base rent under this lease will be $672,000.

OFFICE PROPERTIES

All but two of the Office Properties are Class A office buildings. Each of
the Kilroy LAX, Kilroy Long Beach and SeaTac (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 from two to 12 stories and are easily
accessible from major highways and all but two (Westlake Plaza and the Office
Property located at the La Palma Business Center) are easily accessible from
major airports. Management believes that as a result of these factors the
Office Properties in the Southern California Area achieve among the highest
rent, occupancy and tenant retention rates when compared to other properties
within their respective submarkets and in neighboring submarkets. 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. The Company developed, owns, leases and manages three Office
Properties 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 Los
Angeles International Airport ("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 DirectTV; 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 93.3% was leased as of
September 30, 1996. Kilroy LAX features fiber optic/telecommunications dual
redundancy (one of the few properties in Southern California so equipped) and
multiple lead-lines for both water and power, thereby mitigating the risk of
temporary loss of such services to the facility. The Property was designed and
constructed with above-standard floor loadings and floor-to-ceiling heights to
accommodate the weight and raised floors requirements of computer and other
equipment. The facility is climate controlled in smaller areas which, while
increasing tenant comfort, allows for separate thermostat controls for areas
housing temperature sensitive equipment and reduces costs for after-hour
operations. The facility was designed toward tenant efficiency and convenience
and features an above-standard ratio of elevators to rentable square feet and
provides 24-hour on-site security and management, private dual heliports,
shuttle service to LAX and on-site retail, banking and dining facilities. In
addition, the two 12-story towers are joined by an atrium and are
professionally landscaped creating a pleasant environment. In addition, the
facility has been recognized by the local utility for its energy efficient
heating, ventilating and air conditioning systems which reduce operating costs
for both the Company and its

84
<PAGE>

tenants. Management believes because of these 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 1995, and the nine-month period ended September 30, 1996,
were 90.8%, 91.6%, 92.1% and 93.3%, 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 101,000 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.

Because the book value of the Office Property located at 2240 E. Imperial
Highway will be in excess of 10% of the Company's total assets, additional
information regarding this Property is presented below. The information
presented below gives pro forma effect to the recent 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, 1995.

The Office Property located at 2240 E. Imperial Highway had an occupancy
rate of 100.0% for each of the years ended December 31, 1991 through 1995. As
of September 30, 1996, Hughes Space & Communications occupied approximately
94.6% of the Property's net rentable square feet under two leases. Under the
principal lease for this space, Hughes Space & Communications commenced
occupancy of 101,000 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 net 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 net rentable square foot for the years ended
December 31, 1991 through December 31, 1995 was $23.17, $24.42, $25.22, $17.15
and $11.83, respectively.

The Company's tax basis in the Property for federal income tax purposes as
of December 31, 1995 was approximately $4.1 million (net of accumulated
depreciation and reductions in depreciable basis). The Property is 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 year ended December 31, 1995, the estimated average depreciation rate
for this Property under the modified accelerated cost recovery system was
4.3%. For the 12-month period ending September 30, 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 September 30, 1996 totaled approximately $130,000. Management does not
believe that any capital improvements made during the 12-month period
immediately following the Offering should result in an increase in annual
property taxes.

Because the gross revenues for the Office Property located at 2250 E.
Imperial Highway for the year ended December 31, 1995 were in excess of 10% of
the aggregate gross revenues for all of the Properties, additional information
regarding this Property is presented below. The information presented below
gives pro forma effect to the recent 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, 1995.

The Office Property located at 2250 E. Imperial Highway had an occupancy
rate of 84.0%, 82.5%, 77.8%, 79.8% and 80.9% as of the years ended December

Communications occupied 33% of the Property's net rentable square feet. The
Property's other tenants include companies engaged in the communications,
technology, transportation and healthcare industries. Hughes Space &
Communications commenced occupancy of 96,133 rentable square feet on

Kilroy Airport Center Long Beach was developed in response to a desire by
the City of Long Beach to promote development in the airport area. Phase I of
the project, two office buildings encompassing approximately 225,000 rentable
square feet, was developed by the Company in 1987 and was sold in 1993. The
Company has entered into an agreement to reacquire the Phase I Office
Properties. As of September 30, 1996 the Phase I Office Properties were 96.6%
leased to eight tenants with total annual rental income per leased net
rentable square foot of $15.67 (calculated on the basis of base rent of signed
leases at September 30, 1996, adjusted for contractual increases in base rent
in effect during the 12-month period ending September 30, 1996). Major tenants
include McDonnell Douglas Corporation, Olympus America, Inc. and Devry, Inc.
See "--Acquisition Properties--Kilroy Long Beach Phase I." The Company has
overseen and continues to oversee all leasing and management of Phase I.

Kilroy Long Beach Phase II was developed by the Company in 1989/1990 and
encompasses an aggregate of approximately 395,000 net rentable square feet.
Phases III and IV are planned for future development. See "--Development,
Leasing and Management Activities--Kilroy Airport Center Long Beach."

Kilroy Airport Center Long Beach is subject to three long-term ground leases
under which the Company is ground lessee (assuming the assignment to the
Company of the approximately 14-acre parcel in connection with the acquisition
of Kilroy Long Beach Phase I). The City of Long Beach is the ground lessor
with respect to Kilroy Long Beach Phases I through III and the Board of Water
Commissioners of the City of Long Beach, acting on behalf of the City of Long
Beach, is the ground lessor with respect to Kilroy Long Beach Phase IV. The
basic term under each of the ground leases expires on July 17, 2035. Primary
rent under the leases for Kilroy Long Beach Phases I, II, III and IV is
currently approximately $338,000 per year, $295,000 per year, $75,000 per year
and $77,000 per year, respectively, with such amounts adjusted periodically to
take account of changes in the fair market rental value of the land underlying
each lease.

Because the book value of the Office Property located at 3780 Kilroy Airport
Way will be in excess of 10% of the Company's total assets, additional
information regarding this Property is presented below.

The Office Property located at 3780 Kilroy Airport Way had an occupancy rate
of 70.2%, 70.5%, 69.1%, 78.6% and 63.6% as of the years ended December 31,

SeaTac Office Center at Seattle-Tacoma International Airport. The Kilroy
Group developed and operates the SeaTac Office Center ("SeaTac"), south of
Seattle in SeaTac, Washington, a Class A office development in the Southend
submarket of the Puget Sound region. SeaTac is comprised of two 12-story
towers (constructed in 1977 and 1980, respectively) and a 4-level office and
garage structure with two floors of office space on top (constructed in 1980),
all with views of the Olympic and Coastal mountain ranges. The site is located
directly across from the Seattle-Tacoma International Airport. The facility
currently contains an aggregate of approximately 530,000 square feet of office
space. Current zoning permits up to an additional 500,000 square feet of
development. The facility features 24-hour on-site security and management,
parking for over 1,900 vehicles, computer training and consultation, travel
agencies and a 24-hour restaurant. As of September 30, 1996, SeaTac had
approximately 308,000 rentable square feet of available office space. Major
tenants include First

Nationwide Mortgage Corporation, Lynden, Inc., National Chemsearch, Northwest
Airlines, Inc., Rayonier, Inc., Seattle-First National Bank and Transamerica
Financial Services, Inc.

SeaTac 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. 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, 1995 totaled approximately
$285,000. As of September 30, 1996, the SeaTac Properties were encumbered by a
first mortgage loan having an outstanding principal balance of $20,162,000.
The loan bears interest at a rate of 9.75% per year and is scheduled to mature
on May 15, 2001. See "Note 4. Debt" to the Combined Financial Statements of
the Kilroy Group.

INDUSTRIAL PROPERTIES

Like the Office Properties, the Industrial Properties developed by the
Company (the Industrial Properties other than the Acquisition Properties) 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. While most of the buildings are
occupied by a single tenant, the Industrial Properties developed by the
Company were designed for multi-tenant operations and can be reconfigured 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 from approximately 57,000 to 277,000 square feet.
The Industrial Properties feature high-tech assembly areas and supporting
office space for management and administrative functions.

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 years 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. The leases do not contain purchase
options.

Certain of the Industrial Properties can support additional development and
the Company presently is planning to develop in the next two years, subject to
substantial pre-leasing, approximately 105,000 square feet of additional
leasable area. The Company anticipates that any such development would be
funded with amounts available under the Credit Facility. There can be no
assurance, however, that the Company will be able to successfully develop any
of the Industrial Properties, or obtain financing for any such development on
terms favorable to the Company. See "Risk Factors--Real Estate Financing
Risks" and "--No Limitation on Debt."

DEVELOPMENT, LEASING AND MANAGEMENT ACTIVITIES

Since 1947, the Company and its affiliates have developed millions of 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 receive fees in
connection with its role as developer of various projects, or, in the case of
Kilroy Long Beach, to develop the land for its own account where such
development will result in a favorable risk-adjusted return on investment. In
connection with the Formation Transactions, the Company will succeed to the
Kilroy Group's rights in and to the Development Properties.

The Company or the Operating Partnership will be the manager of the
Properties and may provide building management services for independent
building owners for terms that vary in length but which generally provide

91
<PAGE>

for management fees of 4% to 5% of collected revenue and may also provide for
reimbursement of expenses. The Services Company will provide development
services for the Company and the Operating Partnership, as well as for third
parties, at market rates.

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 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" and "Acquisition Properties." Current development activities are
focused on Phase III of the project ("Kilroy Long Beach Phase III") which will
be developed and owned by the Company. Kilroy Long Beach Phase III presently
is contemplated to initially include a seven-story office building with
approximately 186,000 rentable square feet and a five-story office building
with approximately 132,000 rentable square feet. In addition, Kilroy Long
Beach Phase III may be developed, subject to site plan approval by the City of
Long Beach, to include an additional office building with up to 150,000
rentable square feet of space. The Company is currently in discussions with
several prospective tenants for office space presently planned to be included
in Kilroy Long Beach Phase III. Development of Kilroy Long Beach Phase III is
subject to substantial predevelopment leasing activity and, therefore, the
timing for the commencement of development is uncertain.

Kilroy Long Beach also is planned to include Phase IV ("Kilroy Long Beach
Phase IV"), which will 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
Long Beach offers substantial opportunity for tenant expansion from a location
servicing both Los Angeles and Orange Counties. See "--Office Properties--
Kilroy Long Beach."

Kilroy Long Beach Phase III and Phase IV will be developed by the Company or
the Services Company for the benefit of the Company. Prior to the Formation
Transactions, the Kilroy Group and its affiliates acquired construction
materials at a cost of approximately $6.5 million in connection with the
development of Kilroy Long Beach Phase III. These construction materials will
not be contributed to the Company and the Company will have no obligation to
purchase the materials from the Kilroy Group or to in any way use the
materials in the development and completion of the project. Any decision on
the part of the Company to purchase the materials from the Kilroy Group in the
future will be determined by a majority of the Independent Directors.

Kilroy Airport Center Long Beach is subject to three long-term ground leases
under which the Company is ground lessee. The City of Long Beach is the ground
lessor with respect to Kilroy Long Beach Phase III and the Board of Water
Commissioners of the City of Long Beach, acting on behalf of the City of Long
Beach, is the ground lessor with respect to Kilroy Long Beach Phase IV. The
basic term under each of the ground leases expires on July 17, 2035. Primary
rent under the leases for Kilroy Long Beach Phases III and IV is currently
approximately $75,000 per year and $76,764 per year, respectively, with such
amounts adjusted periodically to take account of changes in the fair market
rental value of the land underlying each lease.

Riverside Judicial Center. In a unique "public-private partnership" with the
City of Riverside Redevelopment Agency and the County of Riverside, the
Company has substantially completed for a fee a comprehensive master planning,
design, entitlement and development effort for the initial phase of a multi-
jurisdictional judicial center complex (the "Riverside Judicial Center") in
downtown Riverside that is expected to serve the entire greater Riverside and
San Bernardino area. Riverside is located approximately 56 miles east of Los
Angeles. The project currently includes a United States Bankruptcy Court and
administrative complexes. In addition, future development at the site may also
include a United States District Court. Construction of the Riverside Judicial
Center began in February 1996. Upon consummation of the Formation
Transactions, the Services Company will be assigned the Development Management
Agreement in connection with the project.

Northrop Grumman. The Company has been retained on a fee basis by Northrop
Grumman Corporation ("Northrop Grumman") to undertake a comprehensive, multi-
phased effort to analyze, entitle and manage the future reuse, planning,
entitlement, marketing and disposition of the approximately 200-acre property
located in the City of Pico Rivera, located approximately 13 miles east of Los
Angeles, which currently serves as Northrop Grumman's headquarters for
activities related to the U.S Air Force's B-2 "Stealth" Bomber Program. Early
stages of the project are underway, including the execution of a Memorandum of
Understanding with the City of Pico Rivera and a community outreach program
and submission of a conceptual reuse plan to the City of Pico Rivera. The
agreement runs through February 15, 1997.

ACQUISITION PROPERTIES

The Company has entered into agreements to acquire from non-affiliated third
parties four office properties and two industrial properties upon consummation
of the Offering, and will acquire one Industrial Property which was purchased
from a non-affiliated third party by KI on behalf of the Company prior to
consummation of the Offering and will be assigned to the Company upon
consummation of the Offering (collectively, the "Acquisition Properties"). In
the event one or more of the Acquisition Properties are purchased, the Company
expects to finance the acquisition cost (approximately $49.0 million in the
aggregate) with long-term borrowings under the $84.0 Million Loan, new
mortgage financing and/or the proceeds of the Offering. Acquisition of each of
these properties is subject to the satisfactory completion of certain closing
conditions. Although each of the acquisitions is expected to be completed
prior to or concurrent with consummation of the Offering there is no assurance
that any of the Acquisition Properties will be acquired. In addition,
concurrent with the Offering the Company will assume and repay out of the
Offering proceeds the indebtedness incurred by KI (on behalf of the Company)
to acquire the Industrial Property located at 12752-12822 Monarch Street,
Garden Grove, California (including expenses at closing). Unless otherwise
indicated, all calculations and information contained in this Prospectus give
pro forma effect to the acquisition of the Acquisition Properties.

Kilroy Long Beach Phase I. Two of the Acquisition Properties comprise Kilroy
Long Beach Phase I, a Class A office complex which includes a two-story office
building and a combination two/three-story office building encompassing an
aggregate of 225,000 rentable square feet. The Company has entered into an
agreement for the purchase of these Office Properties for an aggregate
purchase price of $23.5 million. Kilroy Long Beach Phase I was developed by
the Company in 1987 and sold by the Company to the current owner, a non-
affiliated third party, in 1993. The Company has overseen all leasing and
management activity at the property since its development. As of September 30,
1996, the properties were 96.6% leased to eight tenants at an average annual
base rent per net rentable square foot of $15.90. See "--Office Properties--
Kilroy Long Beach."

Thousand Oaks Office Property. Another Acquisition Property is a stand-alone
three-story Class A office property located in Thousand Oaks, California,
which encompasses approximately 81,100 rentable square feet and, as of
September 30, 1996, was 100.0% leased to eleven tenants at an average annual
base rent per net rentable square foot of $23.26. The Company has entered into
an agreement with a non-affiliated third party for the purchase of this Office
Property for a purchase price of $13.2 million.

93
<PAGE>

Anaheim Office and Industrial Properties. The Company also has entered into
an agreement to purchase one office and two industrial properties located at
4123-4175 East La Palma Avenue, Anaheim, California. The Office Property
consists of approximately 42,800 rentable square feet. At September 30, 1996,
the Office Property was 91.6% leased to 11 tenants at an average annual base
rent per net rentable square foot of $12.37. The Industrial Properties
comprise an aggregate of approximately 144,000 rentable square feet. At
September 30, 1996, each of the Industrial Properties was 100% leased with an
aggregate annual base rent per net rentable square foot of $4.47. Pursuant to
the terms of the purchase agreement, the Company will acquire all of these
properties for an aggregate purchase price of $12.2 million in cash.

12752-12822 Monarch Street, Garden Grove, California. On behalf of the
Company, in December 1996 KI purchased an industrial building located at
12752-12822 Monarch Street, Garden Grove, California. The building contains an
aggregate of approximately 277,000 rentable square feet. As of September 30,
1996, the property was 100% leased to five tenants at an average annual base
rent per net rentable square foot of $3.38. Pursuant to the terms of the
purchase agreement, the Property was acquired on behalf of the Company for a
purchase price of $9.1 million in cash and will be transferred to the Company
concurrent with the Offering. The Company will assume and repay out of the net
proceeds of the Offering the debt and expenses incurred by KI in connection
with the acquisition. The purchase was completed on behalf of the Company in
December 1996 because of the closing schedule required by the seller.

THE COMPANY'S 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, industrial and retail 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 (the "Southern California Area") 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 new construction of industrial properties.

* 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 and under the caption "Prospectus Summary--The Company's
Southern California Submarkets" 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.

As of December 31, 1995, the Southern California Area had a total population
of approximately 15.6 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 217,000 persons. Of the
approximately 15.6 million people in the Southern California Area,
approximately 9.2 million persons lived in Los Angeles
County and approximately 2.6 million persons lived in Orange County. Annual
estimated growth in population in these counties over the next five years is
expected to be approximately 94,000 and 32,000 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 experienced
significant recessionary conditions 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. Employment growth recovered
in 1995. The passage of the North American Free Trade Agreement (NAFTA) in the
first quarter of 1995 and the General Agreement on Tariffs and Trade (GATT) in
the fourth quarter of 1994 provide optimism for new jobs and economic growth
for California. In 1995, the Southern California Area experienced a net
increase in employment with the addition of approximately 113,000 jobs,
representing an approximately 1.9% increase over the prior year. Of the total,
approximately 61,000 jobs (approximately 53.9% of the total) were created in
Los Angeles County. Employment in the Southern California Area is expected to
increase during 1996 through 1998, with an expected average increase of
approximately 125,000 to 135,000 jobs annually, representing an annual growth
rate of approximately 2.1%

95

to 2.2%, nearly twice the expected national growth rate of 1.2%. The following
table shows the annual non-agricultural change in jobs for the Southern
California Area for the period from 1980 through 1995, and the expected change
in jobs for the period from 1996 through 1998.

Unemployment rate in the Southern California Area is moving downward from
its 1993 peak. For the U.S., the 1995 unemployment rate was approximately 6.2%
versus approximately 7.7% in California. By comparison, the 1993 unemployment
rates for the U.S. and California were approximately 6.9% 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 1995 unemployment rates vary from a low of approximately
5.4% in Orange County to a high of approximately 8.7% in Riverside and San
Bernardino Counties. Los Angeles County's unemployment rate stood at
approximately 7.7%--the same as California's.

Diversification of Industries. Los Angeles and Orange Counties are widely
regarded as major centers for corporate and international business and 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 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 in which the Properties are located.

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 11.4% during the ten-year period ended in 1994 compared to an
approximately 8.0% 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.

Growing Service Economy. Over the last 15 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 20.1% in 1995. Within this sector, manufacturing accounted for
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 79.9% in
1995. The following table presents the total employment growth from 1980 to

Office Submarkets. Total office space in the Southern California Area
amounts to approximately 229.2 million square feet. The Southern California
Area is the second largest office market in the country after the New York
City Metro Area (with over approximately 800 million square feet). Los Angeles
County comprises two-thirds of the metro office inventory, roughly 156.1
million square feet; Orange County accounts for approximately 54.2 million
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%. At September 30, 1996, the
vacancy rate for the Southern California Office Properties was approximately
6.9%. The following table shows the U.S. and Southern California Area office

million and 1994's total of 2.7 million and nearly double 1993's total of
approximately 1.7 million square feet. By comparison, absorption in the
Southern California Area ranged from approximately 11.1 million to 11.7
million square feet during the mid- to late 1980s. Annual increases in
employment during the 1980s fluctuated between approximately 160,000 and

construction of office space in the Southern California Area has decreased
substantially. The following table shows the additions in square footage to
the Southern California office market for each of the last eight years.

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

The addition in the near-term of any new speculative office space to the
market remains unlikely as effective rents for multi-tenant properties are
currently well below the level needed to make new construction economically
feasible.

El Segundo Office Submarket. In the El Segundo submarket the Company owns
and operates three Office Properties 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 quality and strategic location
of the four Office Properties located in the El Segundo submarket, the El
Segundo Office Properties have had 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 19.8% as of September 30, 1996 as compared to approximately 7.0%
for the Company's El Segundo Office Properties as a whole as of September 30,
1996. The average asking annual rental rate in the El Segundo submarket as of
September 30, 1996 was approximately $22.00 per square foot for Class A office
buildings compared to an average asking annual rental rate of $24.00 per
square foot for the Company's El Segundo Office Properties as of September 30,
1996. 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

Through September 30, 1996, net absorption of Class A office space in the El
Segundo submarket was a negative 357,000 square feet, principally the result
of the 500,000 net rentable square feet of office space owned by an
unaffiliated third-party located at 200 North Sepulveda Boulevard and vacated
by Hughes Electronics early in 1996. During the same period, Hughes Space &
Communications extended leases for office space located at Kilroy LAX covering
over 107,000 net rentable square feet. Local brokers indicate that the office
space located at 200 North Sepulveda Boulevard is among the lower quality
Class A buildings in the El Segundo submarket and is not conducive to most
tenants seeking a better quality Class A product as offered at Kilroy LAX.
During the year ended 1996, rents at Kilroy LAX remained relatively unaffected
by the addition of the lower quality space to the vacant inventory.

Management believes that the submarket's expanding economy, the availability
of large blocks of office space and lower rental rates than those offered in
the nearby West Los Angeles office submarket should apply some short-term
upward pressure on rents for quality Class A office space by as much as 5.0%
within the next year. Rental rates at lower quality (non-Class A) buildings
are expected to be flat until vacancies drop to a level of at least 15%.

Long Beach Airport Area Office Submarket. Upon consummation of the Offering
and the Formation Transactions, the Company will own five Office Properties at
Kilroy Long Beach Phases I and II which represent approximately 42% of the
total rentable square feet of all Class A office properties located in the
Long Beach Airport area submarket.

The Long Beach Airport area submarket is strategically located near the
border of Los Angeles and Orange Counties, adjacent to the I-405 Freeway and
is in close proximity to several other freeways which serve the area. The
submarket is also near the Long Beach Airport which, through AmericaWest
Airlines, provides commercial airline access to all regions of the country.
The Long Beach Airport area submarket provides tenants with the ability to
draw a workforce from and to provide services to clients in both Los Angeles
and Orange Counties, making it an ideal location for companies operating in
both counties to consolidate their operations to a convenient single location.
In addition, portions of the submarket, including the Properties located at
Kilroy Airport Center Long Beach, are located within a favorable tax zone
which permits qualifying tenants to receive a variety of tax credits and
deductions not available in neighboring submarkets. The submarket also offers
tenants a secure environment within a first class office park with the
potential for substantial expansion, whereas the Long Beach central business
district submarket is hampered by traffic congestion and limited opportunities
for tenant expansion.

As of September 30, 1996, the vacancy rate of Class A office buildings in
the Long Beach Airport area submarket was approximately 16.6% as compared to
approximately 8.6% for the Company's Long Beach Office Properties. For the
year ended December 31, 1996, the submarket experienced net absorption of
approximately 20,000 rentable square feet of office space, as compared to
approximately 458,000 rentable square feet for the year ended December 31,
1995, of which 275,000 rentable square feet was attributable to two leases
entered into by McDonnell Douglas at the Long Beach Airport Business Park. As
of December 31, 1996 and 1995, the mean asking annual rental rate in the Long
Beach Airport area submarket was approximately $22.00 and $24.40,
respectively, per rentable square foot for Class A office buildings compared
to the mean asking annual rental rate at Kilroy Long Beach of $24.00 and
$24.30, respectively, per rentable square foot.

The decrease in the submarket's vacancy rate, the indications of improvement
in the submarket's aerospace industry and the present difficulty in locating
large blocks of contiguous space should apply some short-term upward pressure
on rents for Class A office space within the next two years. Available space
for technology companies is particularly difficult to find and buildings which
offer current telephone communication capabilities and electrical support are
more likely to benefit earlier.

Thousand Oaks Submarket. Upon consummation of the Offering and the Formation
Transactions, the Company will own a stand-alone three-story office building
located in Thousand Oaks, California. The City of Thousand Oaks has
approximately 112,600 residents, and is located 40 miles northwest of Los
Angeles in

103
<PAGE>

Ventura County, which is located along the coast immediately north of Los
Angeles County. As of December 31, 1995, Ventura County had a population of
approximately 720,000 persons. The County is home to companies in various
industries including high technology, pharmaceuticals and finance. As of
December 31, 1996, the vacancy rate of office space in the Ventura County
office submarket was approximately 13.6%. 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. The average annual effective gross rent for office space in the
Ventura County office submarket as of December 31, 1996 was $17.76 per square
foot, an increase of 17.5% over 1995.

Industrial Submarkets.

As of December 31, 1996, available industrial space in the Southern
California Area totaled approximately 1.2 billion 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 7.6% at December
31, 1996. At September 30, 1996, the vacancy rate for the Industrial
Properties was approximately 6.3%. The following table shows the U.S. and
Southern California Area industrial vacancy rates for the period from 1991
through 1996.

Much of the existing space on the market 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 modest growth in new
construction primarily of build-to-suit. In addition, speculative construction
also grew modestly in 1996 with approximately 7.0 million square feet of new
construction representing approximately 0.6% of the region's inventory.
However, this amount still is relatively modest when compared to 1989 levels
when new construction for the year reached approximately 34.0 million square
feet, and the existing building inventory was approximately 1.0 billion square
feet.

El Segundo Industrial Submarket. The Company owns four Industrial Properties
located in the City of El Segundo, which contain an aggregate of approximately
390,000 rentable square feet. The El Segundo industrial submarket is part of
the South Bay industrial market which includes the cities of Torrance, Carson
and Long Beach. At September 30, 1996, the Company's El Segundo Industrial
Properties were 98.1% leased to three tenants. At December 31, 1996, the South
Bay industrial market contained approximately 185 million rentable square feet
of industrial space, with a vacancy rate of approximately 8.0%.

Orange County Industrial Submarket. Upon consummation of the Offering, the
Company will own seven Industrial Properties in Orange County, five of which
are in the City of Anaheim and two of which are in the City of Garden Grove.
The seven Industrial Properties located in Orange County contain an aggregate
of approximately 816,877 rentable square feet. At September 30, 1996, the
Company's Orange County Industrial Properties were 90.5% leased to 14 tenants.
At December 31, 1996, the Orange County industrial submarket contained
approximately 207 million rentable square feet, with a vacancy rate of
approximately 8.8%. The low current vacancy rate in the Southern California
industrial submarket as a whole is likely to put upward pressure on rents for
Southern California Class A buildings during 1996, with increases by as much
as 9% by the end of 1997.

SEATTLE MARKET

As of 1995, the population of the Seattle metropolitan statistical area
("Seattle MSA") was 2.2 million making it the 21st largest in the country. The
median per capita personal income in 1995 for the Seattle MSA was $28,329,
which is 22% above the national level.

The Seattle MSA has the 15th largest employment level in the nation. Since
1985, employment has grown at an average annual rate of 3.2%. Industries
concentrated in Seattle include aircraft manufacturing, aircraft parts,
computer and data processing and healthcare. The largest employers in the
greater Seattle area are Boeing Co., The University of Washington, Safeway
Inc., Microsoft Corp. and Group Health Cooperative of Puget Sound.

As of December 31, 1992, the vacancy rate for office space in the Seattle
MSA was 13.2%. Since then, this rate has steadily declined to a level of 12%
as of December 31, 1994 and 9.1% as of June 30, 1996. The Seattle MSA's
aggregate office space of 51.3 million square feet made it the 14th largest in
the nation and, as of June 30, 1996, it contained 35.2 million square feet of
Class A office space with a vacancy rate of 8.7%. Over the last three years
only 581,000 square feet of office space has been added to the Seattle MSA.

EXCLUDED PROPERTIES

The Company will hold 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 at the respective purchase price for each
of the properties as discussed below. The office complex was developed and has
been leased and managed by the Kilroy Group and each option property is
currently owned by a partnership beneficially owned and controlled by John B.
Kilroy, Sr. and John B. Kilroy, Jr. The option for Calabasas Park Centre is
exercisable on or before the first anniversary of the Offering. The option for
the office complex located on North Sepulveda Boulevard in El Segundo is
exercisable on or before the seventh anniversary of the consummation of the
Offering. The purchase price for each of the properties will be payable in
cash, provided, however, that if the option for the office complex in El
Segundo is exercised after the first anniversary of the consummation of the
Offering, the purchase price will be payable in cash or Units at the election
of the seller. The Company intends to account for acquisitions of Excluded
Properties, if any, using the purchase accounting method.

In the event that the owner of a property 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

105
<PAGE>

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 shall be 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 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, and for which future entitlements are
expected to include residential 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, hotel and residential
development, of which approximately 1.7 acres is proposed to be dedicated to
the City of Calabasas for civic use. Because these 27 acres are not planned
for development for office or industrial use, management believes that such
parcels are not appropriate for inclusion in the Company's portfolio. 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 expect to 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 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 September 30, 1996, the office
space was 100% leased to Hughes Space & Communications (of which approximately
60% is occupied) at an average annual triple net base rent per net rentable
square foot of $21.06,

106
<PAGE>

subject to a lease scheduled to expire on February 28, 1998. Management
believes that in light of the near-term expiration of the current lease and
the uncertainty of whether the current rental rate will approximate market
rental rates at the time of expiration, this office complex is not appropriate
for inclusion in the Company's portfolio at this time. 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 Patrice Bouzaid, Susan Hahn, Anne McCahon and Dana
Pantuso, the daughters of John B. Kilroy, Sr., have an approximately 4.2%
interest in the limited partnership. Each of Messrs. Kilroy expects to spend
an immaterial amount of time in connection with the management of the
property.

As of September 30, 1996, the office complex was encumbered by a first
mortgage loan having an outstanding principal balance of approximately $61.4
million. The loan bears interest at a rate of 9.63% per year and is scheduled
to mature on February 1, 2005. This property is also encumbered by a second
mortgage loan having an outstanding principal balance as of September 30, 1996
of $3.4 million. This loan bears interest at a rate of 9.75% per year and is
scheduled to mature on February 28, 1998.

Pursuant to the terms of the applicable Option Agreement, the purchase price
for the North Sepulveda Boulevard properties 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 the date of the consummation of the Offering 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 North Sepulveda Boulevard
properties is subject to a right of first offer held by Hughes Space &
Communications.

Other Excluded Properties. In addition to the properties described above,
the Company will not acquire the following properties, each of which is owned
and controlled by John B. Kilroy, Sr. and John B. Kilroy, Jr.: (i) an
approximately three-acre undeveloped parcel located in Tampa, Florida, which
management believes is not appropriate for inclusion in the Company's
portfolio because of the long-term uncertainty of demand for office and
industrial property in the local market; and (ii) an approximately one-half-
acre parcel located in Santa Ana, California which management believes is not
appropriate for inclusion in the Company's portfolio because the parcel is
subject to an easement for railroad use, making the property undesirable for
development for office or industrial use. Each of John B. Kilroy, Sr. and John
B. Kilroy, Jr. will spend an immaterial amount of time managing these
properties.

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 expects to have 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.

All of the Properties were reviewed by an independent engineering
consultant. Each of the Office Properties located at Kilroy LAX, Kilroy Long
Beach and the SeaTac Office Center was reviewed as part of the respective

107
<PAGE>

office complex ("Office Complex") in which each is located and the following
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 was estimated based
upon site-specific seismic ground motion intensities expected to occur at
least once during 50-year and 200-year time periods. 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 only two of the Industrial Properties would be expected to
incur property damage losses in excess of approximately 10% of the RCV. The
two Industrial Properties, located at 12691 Pala Drive, Garden Grove,
California and 1230 South Lewis Street, Anaheim, California, are expected to
incur 50-year property damage losses of approximately 13% and approximately
14%, respectively, of their RCVs. For seismic ground motion intensities
expected to occur at least once in a 200-year period, these property damage
loss evaluations indicate that only one of the Office Properties (including
the Office Complexes) would be expected to incur property damage losses in
excess of approximately 21% of its RCV. Specifically, the Office Property
located at 185 South Douglas Street, El Segundo, California is expected to
incur a 200-year property damage loss of approximately 40% of its estimated
RCV. With respect to the Industrial Properties, only four would be expected to
incur 200-year property damage losses in excess of 25% of their respective
RCVs. Specifically, Industrial Properties located at 12691 Pala Drive, Garden
Grove, California; 1230 South Lewis Street, Anaheim, California; 2260 E. El
Segundo Boulevard, El Segundo, California; and 2270 E. El Segundo Boulevard,
El Segundo, California, each would be expected to experience property damage
losses of approximately 40% of its respective estimated RCV during a 200-year
seismic disturbance.

The Company has insurance for loss in the event of damage to the Properties
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) for each location per occurrence. The Company's earthquake
insurance might not be sufficient for replacement.

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.

property or to borrow using such property as collateral. In addition, the
presence of such substances may expose it to liability resulting from any
release or exposure of 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.

All of the Properties were subject to Phase I or similar environmental
assessments by independent environmental consultants in connection with the
formation of the Company. 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.
In connection with the preparation of the Phase I environmental survey with
respect to Kilroy Long Beach Phase I, interviews of certain individuals
formerly employed at the site documented in a historical site assessment
survey revealed the site's possible prior use as a Nike missile storage
facility. Further investigation performed by the Company's environmental
consultants and by the Company did not reveal any additional information with
respect to such use of the site. 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. 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.

Company believes that the Properties are currently in material compliance with
all such regulatory requirements. However, the 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 Company's 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. 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 other cities in which
the Properties are located or that new requirements will not be imposed which
would require significant unanticipated expenditures by the Company and could
have a material adverse effect on the Company's Funds from Operations and cash
available for distribution.

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 "Risk Factors--Government
Regulations," "Certain Provisions of Maryland Law and of the Company's
Articles of Incorporation and Bylaws," "Partnership Agreement of Operating
Partnership," "Federal Income Tax Consequences" and "ERISA Considerations."

MANAGEMENT AND EMPLOYEES

The Operating Partnership has been structured as the entity through which
the Company will conduct substantially all of its operations. The Services
Company has been structured as an entity through which the Company will
conduct substantially all of its development activities and related
operations. 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.

The Company (primarily through the Operating Partnership and the Services
Company) initially will employ approximately 47 persons. The Company, the
Operating Partnership and the Services Company will employ substantially all
of the professional employees of KI that are currently engaged in asset
management and administration. The Operating Partnership will employ
approximately 18 on-site building employees who currently provide services for
the Properties. The Company, the Operating Partnership and the Services
Company believe that relations with their employees are good.

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 which 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 of the Company 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 will
conduct all its investment activities through the purchase of interests in the
Operating Partnership until all Units have been redeemed 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, developing
properties, 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 extending
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 expects to pursue its investment objectives primarily through
the ownership of quality office, industrial and retail properties. The
Properties will initially consist of 14 Office Properties and 12 Industrial
Properties. The Company currently contemplates developing and acquiring
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 will not
have any 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
will seek 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, the Company will
also determine 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 will emphasize
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

111
<PAGE>

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 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. See "Partnership Agreement of the Operating
Partnership--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. Upon completion of the Offering and the
Formation Transactions, the debt to total market capitalization ratio (i.e.,
the total consolidated debt of the Company as a percentage of the market value
of the issued and outstanding shares of Common Stock and Units plus total
consolidated debt) of the Company will be approximately 21.5%. 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 will
consider 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.

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

112
<PAGE>

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 would 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. There are no limits on the number or
amount of mortgages or interests which may be placed on any one property. In
addition, such indebtedness 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 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 proposed 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.

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.

CONFLICT OF INTEREST POLICIES

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

Terms of Transfers. The terms of the transfers of the Properties to the
Operating Partnership by the Continuing Investors, and the terms of each of
the option agreements relating to the Excluded Properties, were not determined
through arm's-length negotiation. Partners and affiliates of the Kilroy Group
who are directors

113
<PAGE>

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, 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
Interests" and "Management."

Sale or Refinancing of 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 the
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, on behalf of the Operating Partnership, prior to the seventh anniversary
of the consummation of the Offering, 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 Company's Board of Directors, not to conduct
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. will not be restricted, however, from continuing to own, manage
and lease certain other existing real estate investments owned by him
including, without limitation, certain properties described under "Business
and Properties--Excluded 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 he terminates his employment 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 Company's Board of Directors, not to conduct
property development, acquisition, sale or management activities in any
market. Notwithstanding the foregoing, John B. Kilroy, Jr. will not be
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--Excluded 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 Mr. John B. Kilroy, Sr. and Mr. John B. Kilroy, Jr. has agreed to be
limited solely to activities related to the marketing, entitlement and sale of
such properties. Such properties are being actively marketed for sale and are
expected to be sold in the ordinary course of business. Mr. John B. Kilroy,
Sr. and Mr. John B. Kilroy, Jr. each will 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.

License Agreement. The Continuing Investors who are members of the Kilroy
family will enter into a license agreement (the "License Agreement") pursuant
to which such Continuing Investors will grant 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 Continuing Investors will retain the right to
use the Kilroy name for commercial endeavors, including in connection with
real estate transactions. Such activities will be subject to the limitations
set forth in the agreements described under the caption "--Noncompetition
Agreements."

114

Policies Applicable to All Directors. Under the Company's 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 Company's Articles of Incorporation and Bylaws provide that a majority
of the Company's Board of Directors must be Independent Directors. See
"Certain Provisions of Maryland Law and of the Company's Articles of
Incorporation and Bylaws--Board of Directors."

OTHER POLICIES

The Company intends to operate in a manner that will 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 Company has authority to offer 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. Although it may do so in the future, except
in connection with the Formation Transactions, the Company has not issued
Common Stock or any other securities in exchange for property, nor has it
reacquired any of its Common Stock or any other securities. The Company
expects to issue shares of Common Stock to holders of Units upon exercise of
their exchange rights in the Partnership Agreement of the Operating
Partnership. 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 of the Company 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.

115
<PAGE>

THE FINANCING

THE MORTGAGE LOANS

The Company, on behalf of the Operating Partnership, has obtained written
commitments for mortgage loans totaling $96.0 million (the "Mortgage Loans")
from Morgan Guaranty Trust Company of New York, an affiliate of J.P. Morgan &
Co., the closing of which is a condition to the consummation of the Offering.
The proceeds of the Mortgage Loans principally will be used to repay existing
indebtedness on the Properties. The Mortgage Loans consist of the $84.0
Million Loan and the $12.0 million SeaTac Loan.

The $84.0 Million Loan will require monthly principal and interest payments
based on a fixed rate equal to the sum of the interest rate for U.S. Treasury
Securities maturing 8 years from the date of the closing of the $84.0 Million
Loan plus 1.75%, and will amortize over a 25-year period, maturing in 2005.
The $84.0 Million Loan will be secured by cross-collateralized and cross-
defaulted mortgages on certain of the Properties. The $84.0 Million Loan may
not be repaid during the first four years of the loan term. Thereafter the
loan may be repaid in whole or in part, subject to a prepayment premium. The
$84.0 Million Loan will require reserves for current taxes and insurance,
capital expenditures and tenant improvements and leasing commissions. Upon
consummation of the Offering, an improvements and repairs reserve of
approximately $1.2 million will be established, which reserve will be released
upon completion of the improvements; a replacement reserve will be funded
monthly at an annual rate of approximately $.20 per square foot of the
collateral; and a reserve of approximately $888,000 will be established to
make certain earthquake-related structural modifications. A tenant improvement
and leasing commission reserve will commence in January 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 will include customary representations and
warranties and will require 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 Company
anticipates that the $84.0 Million Loan will be incurred by a limited
partnership which is wholly-owned by the Company and the Operating Partnership
and which will be structured to be a "bankruptcy remote" financing vehicle.
The Properties to be used as collateral for the $84.0 Million Loan will be
transferred to that limited partnership. Subject to certain limited
exceptions, the $84.0 Million Loan will be non-recourse to the Company.

The SeaTac Loan will bear interest at a variable rate equal to the 30-day
London interbank overnight rate ("LIBOR") plus 3.0%, and matures in July 1997.
The SeaTac Loan will require monthly payments of interest. The SeaTac Loan
will be secured by the ground leasehold interest in the SeaTac Office Center.
Principal and interest under the SeaTac Loan will be full recourse to the
Company. SeaTac's occupancy rate was approximately 42.1% at September 30,
1996. The Company excluded the SeaTac Office Center from the collateral pool
for the $84.0 Million Loan to provide flexibility to incur additional debt
secured by the SeaTac Office Center if the Company leases additional space at
this Property. In connection with the $84.0 Million Loan, the Company will pay
fees equal .50% of the total principal amount, or $420,000, and will reimburse
the lender for its costs and expenses. In connection with the SeaTac Loan, the
Company will pay fees equal to 1.5% of the total principal amount, or
$180,000, and will reimburse the lender for its costs and expenses.

The Mortgage Loans may, at the discretion of the lender, be included in a
future securitized financing transaction.

THE CREDIT FACILITY

The Company, on behalf of the Operating Partnership is currently negotiating
with Morgan Guaranty Trust Company of New York, on behalf of the proposed
lenders, a two-year, $100.0 million revolving credit facility (the "Credit
Facility") which the Company and the Operating Partnership expect to enter
into shortly after the

116
<PAGE>

Offering. There can be no assurance that the Company and the Operating
Partnership will enter into the Credit Facility. The Credit Facility is
expected to be used primarily to finance acquisitions of additional
properties. Payment of principal and interest is expected to be secured by
certain Properties other than Properties securing the Mortgage Loans. In
addition, borrowings under the Credit Facility are expected to be recourse
obligations to the Operating Partnership and the Company.

Availability under the Credit Facility would be subject to the value of the
underlying collateral securing it. The Company expects that, initially,
approximately $50.0 million of the total amount of the Credit Facility would
be available to the Operating Partnership. The Operating Partnership's ability
to borrow under the Credit Facility is expected to be 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 60.0%; 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 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 90.0% of the
Operating Partnership's consolidated tangible net worth as of the closing date
for the Credit Facility; 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 on total
development projects to 20% of total assets; limitations on the incurrence of
additional indebtedness; and other customary covenants. "Debt Service" means,
measured as of the last day of each calender 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. "Net
Operating Cash Flow" means, as of the first day of each month for the
immediately preceding month, all property income as shown on the Operating
Partnership's financial statements, less all operating expenses of the
Operating Partnership during such period, which operating expenses shall not
include (i) depreciation, amortization or other non-cash expenses, (ii) income
taxes, (iii) all costs and expenses (including, without limitation, attorneys'
fees and disbursements and other professional fees and expenses) incurred in
connection with the transactions contemplated by the Credit Facility, or (iv)
capital expenditures. The Credit Facility is expected to require monthly
interest only (LIBOR based) payments on the total borrowings outstanding under
the Credit Facility. 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 Company and the
Operating Partnership will be responsible for payment of the lender's fees and
expenses associated with providing the Credit Facility. In connection with the
Credit Facility, the Operating Partnership will pay fees equal to 1.0% of the
total commitment under the Credit Facility, or $1.0 million, and will
reimburse the lenders for its costs and expenses.

MANAGEMENT

DIRECTORS AND EXECUTIVE OFFICERS

Upon consummation of the Offering, the Board of Directors will consist of
five members, including a majority of directors who are Independent Directors.
Directors of the Company will be 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 Offering
will be held in 1998. Each of the proposed directors named below has been
nominated for election upon the consummation of the Offering and has consented
to serve. See "Certain Provisions of Maryland Law and of the Company's
Articles of Incorporation and Bylaws--Board of Directors." Subject to rights
pursuant to any employment agreements, officers of the Company serve at the
pleasure of the Board of Directors.

The following table sets forth certain information with respect to the
directors, proposed directors and executive officers of the Company
immediately following the completion of the Formation Transactions and
consummation of the Offering:

of certain benefits including medical insurance, life and disability insurance
and the receipt of other customary benefits established by the Company for its

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

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 consent. "Change of
Control" means (a) the event by which the individuals constituting the board
of directors as of the date of the Company's initial public offering of Common
Stock cease for any reason to constitute at least a majority of the Company's
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 has established 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

122
<PAGE>

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 Company's 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 Company's Articles of Incorporation or as otherwise permitted
by the Board of Directors) of nonqualified stock options.

Stock Options. Promptly after the closing of the Offering, the Company
expects to issue 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 Company's Articles of Incorporation or as otherwise permitted by the Board
of Directors, 900,000 shares of Common Stock pursuant to the Stock Incentive
Plan. The term of each of such option will be ten years from the date of
grant. Each such option will vest 33 1/3% per year over three years and is
exercisable at a price per share equal to the initial public offering price
per share of Common Stock in the Offering. The following table below sets
forth the expected allocation of the options to such persons.

</TABLE>

An additional 500,000 shares of Common Stock will be 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 made 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 will have voting rights and
will receive distributions prior to the time when the restrictions lapse. The
Company will issue 100,000 restricted shares of Common Stock reserved for
issuance under the Stock Incentive Plan, to Richard E. Moran Jr. upon
consummation of the Offering.

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.

123
<PAGE>

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 will be issued, and options covering 900,000
of which will be granted, under the Stock Incentive Plan upon the consummation
of the Offering.

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.

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 of the Company 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.

124
<PAGE>

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.

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 ten years from the date
the Offering is consummated, unless sooner terminated by the Board of
Directors.

Registration Statement on Form S-8. After the consummation of the Offering,
the Company expects to cause to be filed 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.

FEDERAL INCOME TAX CONSEQUENCES TO PARTICIPANTS IN THE STOCK INCENTIVE PLAN

The following summary of the material federal income tax consequences to
participants in the Stock Incentive Plan is based on current law, is for
general information only and is not tax advice. The summary does not purport
to discuss all aspects of federal income taxation that may be relevant to a
particular participant in light of such participant's personal investment
circumstances.

A participant may be subject to state or local taxation in various state or
local jurisdictions in which he or she works or resides. State and local tax
treatment of the participants are not discussed in this summary, and such
state and local tax treatment may not conform to the federal income tax
consequences discussed in this summary.

Non-Qualified Stock Options. A participant who is granted non-qualified
stock options does not realize income as a result of the grant of such
options. However, the participant normally realizes compensation income at the
time the options are exercised, in the amount by which the fair market value
of the Common Stock on the date the options are exercised exceeds the option
exercise price paid. This compensation income is taxable at

125

ordinary income rates, and the Company is required to withhold taxes on the
amount treated as ordinary income to the participant.

The participant's tax basis for Common Stock acquired upon the exercise of a
non-qualified stock option is the price paid to exercise the option plus the
amount of ordinary income realized by the participant as a result of the
exercise of the option. Any appreciation in the value of such Common Stock may
qualify for capital gains treatment, provided that applicable holding period
requirements are satisfied.

The tax consequences resulting from a participant's exercise of non-
qualified options by surrendering Common Stock already owned by the
participant are not completely certain. In published rulings, the Internal
Revenue Service (the "IRS") has taken the position that, to the extent that
the number of shares acquired is equivalent to the number of shares
surrendered, the participant recognizes no gain and the participant's basis in
the shares acquired upon such exercise is equal to the participant's basis in
the surrendered shares, that any additional shares acquired upon such exercise
is compensation to the participant taxable under the rules described above,
and that the participant's basis in any such additional shares will be their
fair market value.

Incentive Stock Options. A participant who is granted incentive stock
options is not treated as having received taxable income upon either the grant
or the exercise of the options. Instead, such participant is taxed at the time
of the sale or other taxable disposition of the Common Stock acquired pursuant
to the exercise of the option. Generally, such participants pay taxes at long-
term capital gains rates on the difference between the amount realized on the
sale or other disposition of the shares and the option exercise price. To
qualify for such capital gains treatment, the participant (i) must not sell or
dispose of the shares earlier than two years from the date of grant of the
incentive stock option or one year from the date of transfer of the shares to
the participant upon exercise, and (ii) must be an employee of the Company at
all times during the period beginning with the date of the grant of the option
and ending three months before the date of exercise. If the shares of stock
are sold or otherwise disposed of before the end of the one-year period or the
two-year period, a portion of the gain, if any, may be treated as compensation
taxable as ordinary income rather than as capital gain.

The tax consequences resulting from a participant's exercise of incentive
stock options by surrendering shares of Common Stock already owned by the
participant are not completely certain. In published rulings and proposed
regulations, the IRS has taken the position that generally the participant
recognizes no income upon such stock-for-stock exercise, that to the extent
that the number of shares acquired is equivalent to the number of shares
surrendered, the participant's basis in the shares acquired upon such exercise
is equal to the participant's basis in the surrendered shares increased by any
compensation income recognized by the participant, that the participant's
basis in any additional shares acquired by such exercise is zero, and that any
sale or other disposition of the acquired shares within the one-year period or
the two-year period described above is viewed as a disposition of the shares
with the lowest basis first.

Alternative minimum tax must be paid when it exceeds a taxpayer's regular
federal income tax. Alternative minimum tax is calculated based on alternative
minimum taxable income, which is taxable income for federal income tax
purposes, modified by certain adjustments and increased by tax preference
items. For purposes of the foregoing, the difference between the exercise
price and the fair market value of shares of Common Stock acquired pursuant to
the exercise of an incentive stock option is classified as alternative minimum
taxable income for the year of exercise. For alternative minimum tax purposes
(but not for regular income tax purposes), the participant's basis in the
acquired shares is the fair market value of the shares at the time the
incentive stock option is exercised. A disqualifying disposition of the
acquired shares during the same year in which the incentive stock option was
exercised will cancel the alternative minimum taxable income generated upon
exercise of the incentive stock option. Should there be a disqualifying
disposition in a year other than the year of exercise, the income on the
disqualifying disposition will not be considered income for alternative
minimum tax purposes.

FEDERAL INCOME TAX CONSEQUENCES TO THE COMPANY

The following summary of the material federal income tax consequences to the
Company is based on current law, is for general information only and is not
tax advice.

Section 162(m) Limitation. Subject to a limited number of exceptions,
Section 162(m) of the Code denies a deduction to a publicly held corporation
for payments of remuneration to certain employees to the extent the employee's
remuneration for the taxable year exceeds $1,000,000. For this purpose,
remuneration attributable to stock options is included within the $1,000,000
limitation. However, to the extent that the remuneration is payable solely on
account of the attainment of one or more performance goals and certain other
procedural requirements are met, then such remuneration is not subject to the
$1,000,000 limitation.

The Company has attempted to structure the Stock Incentive Plan in such a
manner that the remuneration attributable to the stock options will not be
subject to the $1,000,000 limitation. The Company has not, however, requested
a ruling from the IRS or an opinion of counsel regarding this issue.

Non-Qualified Stock Options. Subject to the limitations set forth in Code
Section 162(m) and discussed above, the Company is entitled to deduct from its
taxable income the amount that the participant is required to include in
ordinary income at the time of such inclusion.

Incentive Stock Options. The Company is not entitled to any deduction on
account of the grant of the incentive stock options or the participant's
exercise of the option to acquire Common Stock. However, in the event of a
subsequent disqualifying disposition of such shares under circumstances
resulting in taxable compensation to the participant, subject to the
limitations set forth in Code Section 162(m) and discussed above, the Company
is entitled to a tax deduction equal to the amount treated as taxable
compensation to the participant.

SECTION 401(K) PLAN

Effective upon the consummation of the Offering, the Company intends 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.

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. The employees' elective deferrals are immediately vested
and non-forfeitable upon contribution to the Section 401(k) Plan. The Company
currently does not intend to make matching contributions to the Section 401(k)
Plan; however, it reserves the right to make matching contributions 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 Company's Articles of Incorporation and Bylaws--Limitation of
Directors' and Officers' Liability" and "--Indemnification Agreements."

<PAGE>

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Certain directors and executive officers of the Company (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 which have been or will be consummated by
the Company, the Operating Partnership or the Services Company, including the
transfer of certain Properties to the Operating Partnership by the Continuing
Investors, the grant of options with respect to the Excluded Properties and,
if exercised, the purchase by the Company of one or more of the Excluded
Properties from the respective Continuing Investors, the repayment of certain
indebtedness encumbering the Properties and the performance of management and
leasing activities by the Operating Partnership and certain development and
other activities by the Services Company at the Excluded Properties. See
"Formation Transactions." In addition, John B. Kilroy, Sr. has contributed
$1,000 to the Company in exchange for an aggregate of 50 shares of Common
Stock, and upon consummation of the Offering, John B. Kilroy, Jr. and John B.
Kilroy, Sr. each will have contributed cash to the Services Company, which,
upon consummation of the Offering and the Formation Transactions, will
represent a 5.0% economic interest in the Services Company.

PARTNERSHIP AGREEMENT

Concurrently with the completion of the Offering, the Company will enter
into the Partnership Agreement of the Operating Partnership with the various
limited partners of the Operating Partnership. See "Partnership Agreement of
Operating Partnership." John B. Kilroy, Sr. and John B. Kilroy, Jr., who are
limited partners of the Operating Partnership, are directors and/or officers
of the Company.

ASSIGNMENT OF LEASE; VARIOUS SERVICES PROVIDED BY THE SERVICES COMPANY TO THE
KILROY GROUP

Concurrently with the completion of the Offering, KI will assign to the
Operating Partnership all of its interest as a tenant in a lease with a
partnership affiliated with the Continuing Investors covering the space
currently serving as the headquarters of KI at Kilroy LAX in El Segundo,
California. The Company, the Operating Partnership and the Services Company
will 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 will provide
management and leasing services, and the Services Company will provide
development services, with respect to the Excluded 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--Development, Management and Leasing--Excluded
Properties."

BENEFITS OF THE FORMATION TRANSACTIONS TO CERTAIN EXECUTIVE OFFICERS

In connection with the Formation Transactions, John B. Kilroy, Sr., Chairman
of the Company's Board of Directors, will receive Units, the repayment of a
personal loan and the termination of guarantees of loans secured by certain of
the Properties. Also in connection with the Formation Transactions, John B.
Kilroy, Jr. will receive Units, as well as the termination of guarantees of
loans secured by certain of the Properties and certain benefits under his
employment agreement with the Company. See "Use of Proceeds". In addition,
each of John B. Kilroy, Sr. and John B. Kilroy, Jr. own and control Kilroy
Calabasas Associates, a California limited partnership, and Kilroy Airport
Imperial Co., a California limited partnership, which, upon the exercise of
certain options by the Company, may transfer certain of the Excluded
Properties to the Operating Partnership in exchange for cash or Units. In the
event that the Independent Directors determine to cause the Company to
exercise its options to purchase these properties, John B. Kilroy, Sr. and
John B. Kilroy, Jr. will receive the consideration paid therefor. See
"Business and Properties--Development, Management and Leasing--Excluded
Properties."

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 Company's 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 and Formation
Transactions, there will be 12,600,000 shares of Common Stock issued and
outstanding (including 100,000 restricted shares of Common Stock granted to an
officer of the Company who is not a Continuing Investor and excluding the
1,875,000 shares which are subject to the Underwriters' over-allotment option
and shares that may be issued upon the exchange of outstanding Units), and no
shares of Preferred Stock will be issued and outstanding.

COMMON STOCK

Each outstanding share of Common Stock will entitle 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 will possess the exclusive voting power,
subject to the provisions of the Company's 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 Company's Articles of Incorporation or as
otherwise permitted by the Board of Directors described below. Holders of
shares of Common Stock will 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 to be issued and outstanding following
the consummation of the Offering will be duly authorized, fully paid and
nonassessable. 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 Company's Articles of
Incorporation or as otherwise permitted by the Board of Directors described
below, distributions may be paid to the holders of shares of Common Stock if
and when authorized and declared by the Board of Directors of the Company out
of funds legally available therefor. The Company intends to make quarterly
distributions, beginning with distributions for the portion of the quarter
from the consummation of the Offering through March 31, 1997. See
"Distribution Policy."

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, all known
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 Company's Articles of Incorporation or as
otherwise permitted by the Board of Directors described below, all shares of
Common Stock will have equal distribution, liquidation and voting rights, and
will 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

130
<PAGE>

shares entitled to vote on the matter unless a lesser percentage (but not less
than a majority of all of the votes 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 of the Company 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 Common 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 will be 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 Company's 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. 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 expects 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 Company's 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

131
<PAGE>

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 Company's Articles of Incorporation or as
otherwise permitted by the Board of 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 the Kilroys' Common Stock under the constructive
ownership rules of the Code will be permitted to own, in the aggregate,
actually or constructively, up to 21% (by number of shares or value, whichever
is more restrictive) of the outstanding Common Stock. See "Description of
Capital Stock--Restrictions on Ownership and Transfer--Ownership Limits."

The Company's 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 owned by fewer than 100
persons. 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 of the Company or any other event would otherwise result in any
person violating the Ownership Limit or such other limit as provided in the
Company's 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 Company's Articles of Incorporation or as otherwise
permitted by the Board of Directors, and distribute to the Prohibited
Transferee or Prohibited Owner 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

132
<PAGE>

to sell such excess shares to a qualified person or entity and distribute to
the Prohibited Owner an amount equal to the lesser of the Market Price (as
defined in the Company's 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,
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 Company's 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. 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
Company's Articles of Incorporation or as otherwise permitted by the Board of
Directors.

CERTAIN PROVISIONS OF MARYLAND LAW AND OF
THE COMPANY'S ARTICLES OF INCORPORATION AND BYLAWS

The following paragraphs summarize certain provisions of the MGCL and the
Company's 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 Company's Articles of Incorporation and Bylaws, copies of
which are exhibits to the Registration Statement of which this Prospectus is a
part.

BOARD OF DIRECTORS

The Company's Articles of Incorporation provide that the number of directors
of the Company shall be established by 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 Board of Directors will consist
of not fewer than five nor more than 13 members. 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 will hold
office initially for a term expiring at the annual meeting of stockholders to
be held in 1998, another class will hold office initially for a term expiring
at the annual meeting of stockholders to be held in 1999 and another class
will hold 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 will help 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 Company's 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 Company's Articles of Incorporation preclude
stockholders from removing incumbent directors except upon a substantial
affirmative vote. Specifically, the Company's 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.

134
<PAGE>

This provision, when coupled with the provision 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 Company's 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

135
<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 Company's Articles
of Incorporation or Bylaws. The Bylaws of the Company contain a provision
exempting from the control share acquisition statute any and all acquisitions
by any person of the Company's shares of stock. Although there can be no
assurance that such provision will not be amended or eliminated at any time in
the future, the Company's Board of Directors has resolved that the provision
may not be amended or eliminated without the approval of the holders of at
least a majority of the 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 Company's 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
Company's Bylaws may be amended by the vote of a majority of the Board of
Directors or the shares of the Company's capital stock entitled to vote
thereon.

MEETINGS OF STOCKHOLDERS

The Company's 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 Company's 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

136
<PAGE>

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.

The provisions in the Company's 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 Company's Articles of Incorporation of the Company and the
Partnership Agreement of the Operating Partnership 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 of the Company 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.

137
<PAGE>

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 the Company to the Company and its stockholders is limited under the
Company's 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 will enter into indemnification agreements with each of its
executive officers and directors. The indemnification agreements will 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. The Company will be the
sole general partner of, and will initially hold approximately 82.6% of the
economic interests in, the Operating Partnership. The Company will conduct
substantially all of its business through the Operating Partnership, except
for development and certain other services (which will be conducted through
the Services Company) in order to preserve the Company's REIT status. The
Operating Partnership will own 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, will have 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 Continuing Investors, as limited partners of the Operating Partnership,
will 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 82.6% of the total partner interests upon consummation
of the Offering). Pursuant to the Partnership Agreement, the limited partners
have agreed not to 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
Continuing Investors 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 82.6%
of all Units outstanding upon consummation of the Offering) and in connection
with which 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

139
<PAGE>

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 Company's 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
basis. Conversely, the partnership interests of the limited partners will be
decreased on a proportionate basis in

140
<PAGE>

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 will 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 Company's 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 the
expiration of two years following the consummation of the Offering 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 Company's 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 Kilroy Industries may be redeemed prior to the second
anniversary of the consummation of the Offering in connection with the
obligation of such Continuing Investors to indemnify the Company in connection
with the Formation Transactions. See "Formation and Structure of the Company--
Allocation of Consideration in the Formation Transactions."

REGISTRATION RIGHTS

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

TAX MATTERS

Pursuant to the Partnership Agreement, the Company will be the tax matters
partner of the Operating Partnership and, as such, will have 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 Operating Partnership."

141
<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 will assume and pay when due, or reimburse 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
the seventh anniversary of the consummation of the Offering, 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.

TERM

The Operating Partnership will continue in full force and effect for 99
years or until sooner dissolved pursuant to the terms of the Partnership
Agreement.

SHARES AVAILABLE FOR FUTURE SALE

GENERAL

Upon the consummation of the Offering and the Formation Transactions, the
Company will have outstanding 12,600,000 shares of Common Stock (including
100,000 restricted shares of Common Stock issued to an officer of the Company
who is not a Continuing Investor and excluding the 1,875,000 shares which are
subject to the Underwriters' over-allotment option), of which the 12,500,000
issued in the Offering (or 14,375,000 if the Underwriters' overallotment
option is exercised in full) will be freely tradeable in the public market by
persons other than "affiliates" of the Company without restriction or
registration under the Securities Act.

Each of the Continuing Investors has agreed not to, directly or indirectly,
offer, sell, offer to sell, contract to sell, pledge, grant any option to
purchase or otherwise sell or dispose (or announce any offer, sale, offer of
sale, contract of sale, pledge, grant of any option to purchase or other sale
or disposition) 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 for a period of
two years from the date of this Prospectus, and the Company has agreed not to
offer, sell, offer to sell, contract to sell, pledge, grant any option to
purchase or otherwise sell or dispose (or announce any offer, sale, offer of
sale, contract of sale, pledge, grant of any option to purchase or other sale
or disposition) of any (other than pursuant to the Stock Incentive Plan)
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, 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. Notwithstanding the foregoing, 50% of
the Units received by John B. Kilroy, Sr., John B. Kilroy, Jr. and Kilroy
Industries in connection with the Formation Transactions will be 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 Continuing Investor and the shares of Common Stock issuable upon
exchange of Units (other than those issued pursuant to registration rights, as
described below), will be subject to Rule 144 promulgated under the Securities
Act ("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 two
years, 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 three years, a person who is not then deemed an
affiliate of the Company is entitled to sell such shares under Rule 144
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. The Commission has stated that it will re-issue a notice of
proposed rulemaking which, if adopted in the form expected to be proposed,
would shorten the applicable holding period under Rule 144(d) and Rule 144(k)
to one and two years, respectively (from the current two- and three-year
periods described above). The Company cannot predict whether such amendments
will be proposed or adopted or the effect thereof on the trading market for
its Common Stock.

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." Upon the consummation

143
<PAGE>

of the Offering, the Company will issue in the aggregate options to purchase
900,000 shares of Common Stock to executive officers, directors and certain
key employees and has reserved 500,000 additional shares of Common Stock for
future issuance under the Stock Incentive Plan.

Prior to the date of this Prospectus, there has been no public market for
the shares of Common Stock. The shares of Common Stock have been approved for
listing on the NYSE, subject to official notice of issuance. 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 Available 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/REGISTRATION RIGHTS

Each limited partner of the Operating Partnership will have 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
beginning two years after the completion of the Offering subject to the
obligation of John B. Kilroy, Sr., John B. Kilroy, Jr. and Kilroy Industries,
with respect to 50% of their Units, to indemnify the Company in connection
with the Formation Transactions. See "Formation and Structure of the Company--
Allocation of Consideration in the 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 Company's Articles of
Incorporation, as applicable. Upon completion of the Formation Transactions,
an aggregate of approximately 2,652,374 Units will be 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 Continuing Investors receiving Units in
connection with the Formation Transactions certain registration rights
(collectively, the "Registration Rights") with respect to the shares of Common
Stock acquired upon exchange of Units or otherwise (the "Registrable Shares").
The Company has agreed to file and generally keep continuously effective
beginning two years after the completion of the Offering 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
Continuing Investors 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 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 plans 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 will be organized and will operate 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 will operate or 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 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 will be organized in conformity with the
requirements for qualification as a REIT, 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, the Operating Partnership and the Services Company, and is
conditioned upon certain representations made by the Company as

145
<PAGE>

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 and assumes that the actions described in this
Prospectus are completed in a timely fashion. 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 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."

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

146
<PAGE>

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 upon consummation of the Offering it will have
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 Company's Articles of Incorporation provides 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 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 Operating Partnership." The Company has direct
control of the Operating Partnership and intends to operate it consistent with
the requirements for qualification as a REIT.

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, 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.

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
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

147
<PAGE>

"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 (unless the
Company determines in its discretion that the rent received from such Related
Party Tenant is not material and will not jeopardize the Company's status as a
REIT); (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.

The Services Company will receive fees in exchange for the performance of
certain development activities. Such fees will not accrue to the Company, but
the Company will derive 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 Company
believes that the aggregate amount of any nonqualifying income in any taxable
year will not exceed the limit on nonqualifying income under the gross income
tests.

The Operating Partnership will receive 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 Excluded 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
"Federal Income Tax Considerations--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 gain
realized by the Operating 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

148
<PAGE>

depends on all the facts and circumstances with respect to the particular
transaction. The Operating Partnership intends to hold the Properties for
investment with a view to long-term appreciation, to engage in the business of
acquiring, developing, owning, and operating the Properties (and other
properties) and to make such occasional sales of the Properties as are
consistent with the Operating 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 the Operating Partnership) must be represented by
real estate assets including (i) its allocable share of real estate assets
held by partnerships in which the Company owns a direct or indirect interest
(such as the Operating Partnership) and (ii) 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 (including its allocable share of the assets held by
the Operating Partnership) 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 will be 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 to be held by
the Operating Partnership will not exceed, at the closing of the Offering, 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.

149
<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 intends to make 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

150
<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, or (iii) is an estate or trust the
income of which is subject to United States federal income taxation regardless
of its source.

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 31 of
such year, provided that the dividend is actually paid by the Company on or
before January 31 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 28% 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 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

151
<PAGE>

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 will report 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. 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 stockholders'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

153
<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 at the closing of the Offering it will be a
"domestically controlled REIT," and therefore that the sale of shares of
Common Stock will not be subject to taxation under FIRPTA. However, because
the shares of Common Stock will be 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.
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
do not alter the substantive withholding and information reporting
requirements but unify current 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 OPERATING PARTNERSHIP

General. Substantially all of the Company's investments will be held
indirectly through the Operating 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 will include 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 will include its proportionate
share of assets held by the Operating Partnership. See "--Taxation of the
Company."

Entity Classification. The Company's interest in the Operating Partnership
involves special tax considerations, including the possibility of a challenge
by the IRS of the status of the Operating Partnership as a partnership (as
opposed to an association taxable as a corporation) for federal income tax
purposes. If the Operating Partnership was 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 "Federal Income Tax Consequences--
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 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 Regulations apply for tax periods beginning on or
after January 1, 1997 (the "Effective Date"). Unless it

155
<PAGE>

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. The Company has not requested, and does not intend to request, a
ruling from the IRS that the Operating Partnership will be treated as a
partnership for federal income tax purposes. However, in connection with the
closing of the Formation Transactions, Latham & Watkins will deliver an
opinion to the Company stating that based on the provisions of the Partnership
Agreement, certain factual assumptions and representations described in the
opinion and the Final Regulations, the Operating Partnership will be treated
as a partnership for federal income tax purposes (and not as an association or
a publicly traded partnership taxable as a corporation). Unlike a private
letter ruling, an opinion of counsel is not binding on the IRS, and no
assurance can be given that the IRS will not challenge the status of the
Operating Partnership as a partnership for federal income tax purposes. If
such challenge were sustained by a court, the Operating Partnership could be
treated as a corporation for federal income tax purposes.

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 Continuing Investors, will
be allocated disproportionately to such Continuing Investors. In addition,
allocations of net income or net loss will be 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 the 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 other Continuing Investors 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

156
<PAGE>

attributable to appreciation, if any, occurring after the closing of the
Formation Transactions. 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."

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 and the Company have not
yet decided which will be used to account for Book-Tax Differences with
respect to the Properties initially contributed to the Operating Partnership.

With respect to any property purchased by the Operating Partnership
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.

Basis in Operating Partnership Interest. The Company's adjusted tax basis in
its interest in the Operating Partnership generally (i) will be equal to the
amount of cash and the basis of any other property contributed to the
Operating Partnership by the Company, (ii) will be increased by (a) its
allocable share of the Operating Partnership's income and (b) its allocable
share of indebtedness of the Operating Partnership and (iii) will be reduced,
but not below zero, by the Company's allocable share of (a) losses suffered by
the Operating Partnership, (b) the amount of cash distributed to the Company
and (c) by constructive distributions resulting from a reduction in the
Company's share of indebtedness of the Operating Partnership.

If the allocation of the Company's distributive share of the Operating
Partnership's loss exceeds the adjusted tax basis of the Company's partnership
interest in the Operating Partnership, the recognition of such excess loss
will be deferred until such time and to the extent that the Company has
adjusted tax basis in its interest in the Operating Partnership. To the extent
that the Operating Partnership's distributions, or any decrease in the
Company's share of the indebtedness of the Operating Partnership (such
decreases being considered a constructive cash distribution to the partners),
exceeds the Company's adjusted tax basis, such excess distributions (including
such constructive distributions) will constitute taxable income to the
Company. Such taxable income will normally be characterized as a capital gain,
and if the Company's interest in the Operating Partnership has been held for
longer than the long-term capital gain holding period (currently one year),
such distributions and constructive distributions will constitute long-term
capital gain.

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

157
<PAGE>

the Company--Asset Tests." This limitation may restrict the ability of the
Services Company to increase the size of its business unless the value of the
assets of the Company or the Operating Partnership is increasing at a
commensurate rate.

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 Partnerships 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

158
<PAGE>

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 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 Company anticipates that the Common Stock will meet the criteria of the
publicly-offered securities exception to the look-through rule. First, the
Company anticipates that the Common Stock will be 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 Company believes that the
Common Stock will be held by 100 or more investors and that at least 100 or
more of these investors will be independent of the Company and of one another.
Third, the Common Stock will be part of an offering of securities to the
public pursuant to an effective registration statement under the Securities
Act and will be 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.

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, through their Representatives, 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 $0.85 per
share, and that such dealers may re-allow a concession of $0.10 per share to
certain other dealers. After the initial public offering, the offering price
and the concessions may be changed by the Representatives.

The Company has granted the Underwriters an option, exercisable for 30 days
from the date of this Prospectus, to purchase up to 1,875,000 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 12,500,000.

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 Representatives of the Underwriters have informed the Company that the
Underwriters do not intend to confirm sales to any accounts over which they
exercise discretionary authority.

Each of the Continuing Investors has agreed not to, directly or indirectly,
offer, sell, offer to sell, contract to sell, pledge, grant any option to
purchase or otherwise sell or dispose (or announce any offer, sale, offer of
sale, pledge, grant of any option to purchase or other sale or disposition) 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 for a period of two years from
the date of this Prospectus, and the Company has agreed not to offer, sell,
offer to sell, contract to sell, grant any option to purchase or otherwise
sell or dispose (or announce any offer, sale, offer of sale, contract of sale,
pledge, grant of any option to purchase or other sale or disposition) of any
(other than pursuant to the Stock Incentive Plan) 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, for a period of 180 days from the date of this
Prospectus, in each case without the prior written consent of Prudential
Securities, on behalf of the Underwriters, subject to certain limited
exceptions. Notwithstanding the foregoing, 50% of the Units received by John
B. Kilroy, Sr., John B. Kilroy, Jr. and Kilroy Industries in connection with
the Formation Transactions will be 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 have been approved for listing on the NYSE. In
order to meet one of the requirements for listing the shares of Common Stock
on the NYSE, the Underwriters have undertaken to sell (i) lots of 100 or more
shares to a minimum of 2,000 beneficial holders, (ii) a minimum of 1.1 million
shares and (iii) shares with a minimum aggregate market value of $40.0
million.

Prior to the Offering, there has been no public market for the Common Stock.
The initial public offering price has been determined through negotiations
between the Company and the Representatives. Among the factors considered in
such determination were prevailing market conditions, dividend yields and
financial characteristics of publicly traded REITs that the Company and the
Representatives believe to be comparable to the Company, the present state of
the Company's financial and business operations, the Company's management,
estimates of the business and earnings potential of the Company and the
prospects for the industry in which the Company operates.

<PAGE>

An affiliate of J.P. Morgan & Co. is expected to provide the Mortgage Loans
and the proposed Credit Facility. In such event, the Company will pay (i) a
debt placement fee to an affiliate of J.P. Morgan & Co. 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 & Co. for the proposed Credit
Facility equal to 1.0% of the maximum amount available thereunder. It is
expected that an affiliate of Prudential Securities will participate in the
Credit Facility.

Upon consummation of the Offering, Prudential Securities will receive
approximately $31.0 million of the net proceeds from the Offering as repayment
of indebtedness, fees and related interest expected to be accrued and unpaid
as of such date. See "Use of Proceeds."

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

The Company will pay to the Representatives advisory fees equal, in the
aggregate, to 0.75% of the gross proceeds received by the Company in the
Offering, for investment banking services relating to, among other things, the
structuring of the Formation Transactions and the Offering.

KILROY REALTY CORPORATION

PRO FORMA CONDENSED CONSOLIDATED BALANCE SHEET

SEPTEMBER 30, 1996
(UNAUDITED)
(DOLLARS IN THOUSANDS)

This unaudited pro forma condensed consolidated balance sheet is presented
as if (i) the transfer of the Properties and business and operations of the
Kilroy Group pursuant to the Formation Transactions and (ii) the Offering, the
Mortgage Loans and use of proceeds to repay indebtedness and purchase the
Acquisition Properties had each occurred on September 30, 1996. Such pro forma
information is based upon the historical balance sheet of the Kilroy Group at
September 30, 1996. The acquisition of the Properties (other than the
Acquisition Properties) and business and operations of the Kilroy Group will
be recorded by the Company at the historical cost reflected in the Kilroy
Group financial statements. The historical cost basis, similar to a pooling of
interests, will be used because these Properties have been under the common
control of John B. Kilroy, Sr. and John B. Kilroy, Jr. The purchase of the
Acquisition Properties will be accounted for as a purchase transaction. Future
acquisitions, including the possible purchase of Excluded Properties, will be
accounted as purchase transactions. This pro forma condensed balance sheet
should be read in conjunction with the pro forma condensed statement of
operations of the Company and the historical combined financial statements and
notes thereto of the Kilroy Group and the historical combined summaries of
certain revenues and certain expenses of the Acquisition Properties included
elsewhere in this Prospectus. See "The Company" and "Use of Proceeds."

The unaudited pro forma condensed balance sheet is not necessarily
indicative of what the actual financial position of the Company would have
been assuming the Company had been formed and the consummation of the
Formation Transactions, the Offering and the Mortgage Loans and the use of
proceeds thereof, and the acquisition of the Acquisition Properties at
September 30, 1996, nor does it purport to represent the future financial
position of the Company.

We have audited the accompanying balance sheet of Kilroy Realty Corporation
(the "Company") as of September 30, 1996. This financial statement is the
responsibility of the Company's management. Our responsibility is to express
an opinion on this financial statement 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 balance sheet is free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the balance sheet. An audit also
includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall balance sheet
presentation. We believe that our audit provides a reasonable basis for our
opinion.

In our opinion, such balance sheet presents fairly, in all material
respects, the financial position of the Company at September 30, 1996 in
conformity with generally accepted accounting principles.

KILROY REALTY CORPORATION

NOTES TO BALANCE SHEET

SEPTEMBER 30, 1996

1. FORMATION OF THE COMPANY

Kilroy Realty Corporation (the "Company") was incorporated in Maryland on
September 13, 1996. The Company will file a Registration Statement on Form S-
11 with the Securities and Exchange Commission with respect to a proposed
public offering (the "Offering") of 12,500,000 shares of Common Stock. The
Company has been formed to succeed to the business of the Kilroy Group
consisting of a portfolio of 19 office and industrial properties (the "Kilroy
Properties") and the real estate ownership, acquisition, development, leasing
and management businesses historically conducted by Kilroy Industries and
related partnerships. The Company's assets will be owned and controlled by,
and all of its operations will be conducted through, Kilroy Realty, L.P. (the
"Operating Partnership") and other subsidiaries. The Company will control, as
the sole general partner, and will initially own an approximately 84.6%
interest in, the Operating Partnership. The Operating Partnership will conduct
certain development services through Kilroy Services, Inc. ("Services
Company"). John B. Kilroy, Sr. and John B. Kilroy, Jr. together will own 100%
of the voting common stock representing a 5% economic interest in the Services
Company. The Operating Partnership will own 100% of the nonvoting preferred
stock representing 95% of the economic interest in the Services Company. The
nonvoting preferred stock will not have any voting rights except as provided
by law, will not be convertible or exchangeable into other securities of the
Company, will have no redemption rights or any appraisal rights except as
provided by law and the holders thereof will have no preemptive rights to
subscribe for any securities of the Company. Holders of the nonvoting
preferred stock will participate in all distributions from the Services
Company and receive 95% of all distributions, if and when such distributions
are authorized and declared by the Services Company's board of directors out
of funds legally available therefor. Upon dissolution, holders of nonvoting
preferred stock will be entitled to receive preferential liquidating
distributions in an amount equal to 95% of the value of the Services Company's
assets. The Operating Partnership's investment in the Services Company will be
accounted for under the equity method. As of October 25, 1996, the Services
Company had not yet been formed.

Prior to and simultaneous with the consummation of the Offering, the
Company, the Operating Partnership and the Continuing Investors intend to
engage in certain formation transactions (the "Formation Transactions")
summarized as follows:

(i) The Continuing Investors will contribute all of their interests in
the Kilroy Properties to the Operating Partnership in exchange for units
representing limited partnership interests in the Operating Partnership
("Units"). The transfer of the Kilroy Properties, which are under the
common control of John B. Kilroy, Sr. and John B. Kilroy, Jr., to the
Operating Partnership will be accounted for at the historical cost of the
Continuing Investors' interests therein similar to a pooling of interests;

(ii) The Company will sell shares of Common Stock in the Offering and
will contribute the net proceeds from the Offering (estimated to be
approximately $262.9 million after deduction of estimated offering
expenses) to the Operating Partnership in exchange for Units in the
Operating Partnership. The Operating Partnership will use substantially all
of such net proceeds, together with the net proceeds of borrowings under
the Mortgage Loans, discussed below, for the repayment of certain existing
mortgage and loan indebtedness on the Kilroy Properties, the acquisition of
certain properties (the "Acquisition Properties") and additions to working
capital cash reserves;

(iii) The Operating Partnership will enter into an $84.0 million secured
mortgage financing and a $12.0 million secured mortgage financing (the
"Mortgage Loans"), which will be nonrecourse obligations of the Operating
Partnership; and

(iv) The Company will amend its charter and authorize 150,000,000 shares
of Common Stock, $.01 par value per share, and 30,000,000 shares of
Preferred Stock, par value $.01 per share.

2. INCOME TAXES

It is the intent of the Company to qualify as a real estate investment trust
("REIT") under the Internal Revenue Code of 1986, as amended. As a REIT, the
Company generally will not be subject to federal income tax to the extent that
it distributes at least 95% of its REIT taxable income to its stockholders.
REITs are subject to a number of organizational and operational requirements.
If the Company fails to qualify as a REIT in any taxable year, the Company
will be subject to federal income tax (including any applicable alternative
minimum tax) on its taxable income at regular corporate tax rates.

3. OFFERING COSTS

In connection with the Offering, affiliates have or will incur legal,
accounting and related costs which will be reimbursed by the Company upon the
consummation of the Offering. These costs will be deducted from the gross
proceeds of the Offering.

4. STOCK INCENTIVE PLAN AND RESTRICTED STOCK GRANT

Prior to the consummation of the Offering, the Company intends to adopt and
have its shareholders approve a stock incentive plan (the "Stock Incentive
Plan"), for the purpose of attracting and retaining executive officers,
directors and employees. A maximum of 1,500,000 shares of Common Stock
(subject to adjustment) will be reserved by the Company for issuance under the
Stock Incentive Plan, including 100,000 restricted shares of Common Stock
which will be issued to an officer of the Company upon consummation of the
Offering and which will vest in equal annual installments over a three-year
period.

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 September 30, 1996 and December 31, 1995 and 1994,
and the related combined statements of operations, accumulated deficit, and
cash flows for the nine months ended September 30, 1996 and each of the three
years in the period ended December 31, 1995 and the combined statements of
operations and cash flows for the nine months ended September 30, 1995. These
financial statements are the responsibility of the management of Kilroy Group.
Our responsibility is to express an opinion on these financial statements
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 September 30, 1996 and
December 31, 1995 and 1994, and the results of its operations and its cash
flows for the nine months ended September 30, 1996 and 1995 and for each of
the three years in the period ended December 31, 1995 in conformity with

1. ORGANIZATION AND BASIS OF PRESENTATION

Organization--Kilroy Group (not a legal entity) consists of the combination
of Kilroy Industries ("KI") and general and limited partnerships, a limited
liability company and trusts, the properties of which are under common control
of KI and/or its stockholders, John B. Kilroy, Sr. and John B. Kilroy, Jr. The
entities referred to collectively as Kilroy Group ("KG") are engaged in the
acquisition, development, ownership and operation of 19 office and industrial
properties (the "Kilroy Properties") located in California, Washington and
Arizona. KI has historically provided acquisition, financing, construction and
leasing services with respect to the Kilroy Properties. KI has also provided
development services to third-party owners of properties for a fee.

The names of the corporation, partnerships and trusts which directly own the
Kilroy Properties are as follows:

KILROY GROUP

NOTES TO 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 Kilroy
Properties are ultimately owned beneficially in the proportions identified
above.

Basis of Presentation--The accompanying combined financial statements of KG
have been presented on a combined basis because of the common ownership and
management and because the entities are expected to be the subject of a
business combination with Kilroy Realty Corporation (the "Company"), a
recently formed Maryland corporation which is expected to qualify as a real
estate investment trust under the Internal Revenue Code of 1986, as amended.
Concurrently with the business combination, the Company intends to raise
capital through an initial public offering of Common Stock, mortgage loans and
a credit facility to be secured by mortgage liens on the properties. The
business combination has been structured to allow the beneficial owners of the
Kilroy Properties (including members of KG) to receive limited partnership
interests in Kilroy Realty, L.P. (the "Operating Partnership") aggregating a
17.4% interest. The Company will be the managing general partner of the
Operating Partnership, which will hold the operating assets and will manage
the Kilroy Properties. 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 7).

2. SIGNIFICANT ACCOUNTING POLICIES

Rental Properties--Rental properties are stated at historical cost less
accumulated depreciation, which, in the opinion of KG's management, is not in
excess of net realizable value. 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.

During 1995, the Company 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--shorter of lease term or useful lives ranging from 5
to 20 years

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 September 30, 1996 and December 31, 1995 and
1994, $202,000, $696,000 and $783,000, respectively, of accrued property taxes
were past due.

KILROY GROUP

NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)

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:

<TABLE>
<CAPTION>

------- ------- ------
Tenants receivables, net.................... $ 3,363 $ 3,973 $3,961
======= ======= ======
</TABLE>

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
September 30, 1996 and December 31, 1995 and 1994 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.

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.

Parking--The Kilroy Airport Center--LAX and the SeaTac Office Center include
parking facilities. KG records as revenue 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 and management fees represent fees earned
by KG for supervision services provided for building development and
management 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 as of December
31, 1995 for the costs of restoration of the property after construction of
the on-ramp.

by KG in the fourth quarter of 1994 for refunds of property taxes paid in 1990
through 1994 and include related interest income of $441,000. Such amounts
were recorded as a reduction of property taxes and as other income during the
year ended December 31, 1994. 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

KILROY GROUP

NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)

$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 and 1994. Past due
interest on the remaining notes, approximately $5,003,000 at December 31,
1995, is included in accrued interest. See discussion below under (c)
regarding settlement of this loan and accrued interest.

(b) During the nine months ended September 30, 1996, three of the notes payable
totaling $16,608,000 were amended to extend the maturity dates from 1996 to
1997 and 1998. In May, 1996, an additional note with a principal balance of
$2,500,000 which was due in February 1996 was amended to extend the
maturity date from February 1996 to 1997. During June 1996, notes payable
of $5,765,000 were amended to extend the maturity date from June 1996 to
April 1998.

(c) On June 20, 1996, KG obtained a mortgage loan of $21,525,000 from one of
the underwriters of the proposed public offering of common stock referred
to in Note 1. Such loan is due on June 20, 1997 and bears interest at 3%
above LIBOR. Fees of $2,279,000 were incurred in connection with obtaining
this loan. An additional fee of $337,500 is payable if the loan is not
repaid within 150 days after June 20, 1996. 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.

(d) KG is not currently making the required monthly principal installments of
$239,000 on this note and accrued interest of $1,894,000 is unpaid as of
September 30, 1996. The SeaTac Office Center is pledged as collateral for
the note payable. On October 25, 1996, KG and the insurance company entered
into a forbearance agreement which provides KG with the exclusive right to
purchase the note payable for $16,100,000 on or before January 31, 1997. In
the event KG does not acquire the loan, the fee owner of the property has
the right from February 1, 1997 through February 28, 1997 to pay off the
loan on the same terms and conditions. In the event KG is unable to acquire
the loan on or prior to January 31, 1997, the fee owner has assigned its
rights to KG for the period February 1, 1997 to February 10, 1997. If KG
fails to perform any of its obligations under the agreement, an event of
default shall occur and the insurance company shall have the right to
pursue any and all remedies available under the agreement and the note
payable, including foreclosure. It is contemplated that a portion of the
proceeds from the initial public offering referred to in Note 1, will be
used to purchase this note. KG believes it will be able to meet this
commitment irrespective of the consummation of the Offering referred to in
Note 1 based upon discussions with other sources of financing.

(e) Under an agreement with the insurance company, monthly payments of
principal and interest are calculated based on gross receipts from leases
of the property that secures the loan. All receipts from the property are
deposited into a lock box account from which all operating costs, which
must be approved by the lender, are to be paid. Monthly installments of
principal and interest of $881,475 and property taxes are payable from the
lockbox account and any deficiency must be funded by KG. There are certain
provisions in the agreement that may require additional payments of
principal.

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.

The notes payable are secured by deeds of trust on all Kilroy Properties and
the assignment of certain rents and leases associated with the related
properties. The notes are generally due in monthly installments of principal
and interest or interest only. As of September 30, 1996, approximately $37.2
million of notes payable are guaranteed by certain members of KG. Several notes
contain restrictive covenants with which KG has complied as well as penalties
for early repayment of principal equal to a percentage of the unpaid balance.

KG 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 to be received under operating leases,
excluding tenant reimbursements of certain costs, are as follows as of:

Rental revenue from one tenant, Hughes Electronic Corporation's Space &
Communications Company ("Hughes"), was $8,161,142, $10,817,000, $11,395,000
and $12,258,000 for the nine months ended September 30, 1996 and the years
ended December 31, 1995, 1994 and 1993, respectively. Future minimum rents
from this tenant are $66,949,000 at December 31, 1995.

On September 18, 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
for the nine months ended September 30, 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.

The majority of Kilroy 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.

lease obligations on the SeaTac Office Center expiring on December 31, 2032
with an option to extend the leases for an additional 30 years. Rentals are

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 position or results of
operations of KG.

7. 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 Kilroy 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--LAX, Kilroy Airport
Center--Long Beach and SeaTac Office Center, under month-to-month leases.
Charges for services provided by KI and KC and rental income from KI are
summarized as follows:

8. 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 $146,352,000, $162,510,000
and $165,325,000 as of September 30, 1996, December 31, 1995 and 1994 have
fair values of $149,600,000, $165,300,000 and $169,900,000, respectively
(excluding prepayment penalties), as estimated based upon interest rates
available for the issuance of debt with similar terms and remaining
maturities. These notes were subject to prepayment penalties of $542,000,
$722,000 and $757,000 at September 30, 1996, December 31, 1995 and 1994,
respectively, that would be required to retire these notes prior to maturity.
The carrying values of floating rate mortgages totaling $77,694,000,
$71,347,000 and $84,734,000 at September 30, 1996, December 31, 1995 and 1994,
respectively, reasonably approximate their fair values.

The fair value estimates presented herein are based on information available
to KG management as of September 30, 1996, December 31, 1995 and 1994.
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.

INDEPENDENT AUDITORS' REPORT

To the Partners of Kilroy Group:

We have audited the accompanying combined historical summaries of certain
revenues and certain expenses (defined as operating revenues less direct
operating expenses) of the Acquisition Properties for the nine months ended
September 30, 1996 and the year ended December 31, 1995. These financial
statements are the responsibility of the Acquisition Properties' management.
Our responsibility is to express an opinion on these combined financial
statements based on our audits.

We conducted our audits 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 audits provide a reasonable basis for our
opinion.

The accompanying combined historical summaries of certain revenues and
certain expenses were 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 summaries 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
summaries are not intended to be a complete presentation of the revenues and
expenses of these properties.

In our opinion, such historical summaries of certain revenues and certain
expenses present fairly, in all material respects, the combined certain
revenues and certain expenses, as defined in Note 1, of the Acquisition
Properties for the nine months ended September 30, 1996 and the year ended
December 31, 1995 in conformity with generally accepted accounting principles.

NOTES TO COMBINED HISTORICAL SUMMARIES OF CERTAIN REVENUES AND CERTAIN
EXPENSES

1. BASIS OF PRESENTATION

The combined historical summaries of certain revenues and certain expenses
relate to the operations of four properties, Westlake Plaza Centre (located in
Thousand Oaks), Long Beach Phase I, La Palma Business Center (located in
Anaheim) and the Monarch Building (located in Garden Grove) (collectively, the
"Acquisition Properties"), which are expected to be acquired by Kilroy Realty
Corporation (the "Company") from four unaffiliated third parties.

Operating revenues and operating expenses are presented on the accrual basis
of accounting. The accompanying statements of certain revenues and certain
expenses are not representative of the actual operations for the period
presented, as certain revenues and certain expenses that may not be comparable
to the revenues and expenses expected to be incurred by the Company in the
proposed future operation of the Acquisition Properties have been excluded.
Revenues excluded consist of termination fees and interest income. Expenses
excluded consist of interest, depreciation, professional fees and other costs
not directly related to the future operations of the Acquisition Properties.

Financial statements for the three years ended December 31, 1995, as
required by Rule 3-14(a)(1), have not been provided because:

(i) the properties were not acquired from a related party;

(ii) material factors such as rental markets and occupancy rates have
been disclosed in the Prospectus under the caption "Prospectus
Summary--The Office and Industrial Properties" and "Business and
Properties--General"; and

(iii) management is not aware of any material factors relating to the
properties that would cause the summaries of certain revenues and
certain expenses for the nine months ended September 30, 1996 and
the year ended December 31, 1995 not to be indicative of future
operating results.

2. OPERATING LEASES

Rental income is recognized on the accrual method as earned, which
approximates recognition on a straight line basis.

The Acquisition Properties are leased to tenants under operating leases with
expiration dates extending to the year 2009. Future minimum rents under the
Acquisition Property's office leases, excluding tenant reimbursements are as
follows as of September 30, 1996:
