Item 1.  Business

THE COMPANY

General

         CarrAmerica Realty Corporation (the "Company") is a fully integrated,
self-administered and self-managed publicly traded real estate investment trust
("REIT") that focuses primarily on the acquisition, development, ownership and
operation of office properties in select growth markets across the United
States. As of December 31, 1999, the Company owned a greater than 50% interest
in a portfolio of 271 operating office properties, and 22 properties under
construction. These 271 operating properties contain an aggregate of
approximately 23 million square feet of net rentable area and the 22 properties
under construction will contain approximately 1.3 million square feet. The
operating properties owned by the Company as of December 31, 1999 were 97.4%
leased as of that date, with approximately 2,000 tenants.

         The Company and its predecessor, The Oliver Carr Company ("OCCO"), have
developed, owned and operated office buildings in the Washington, D.C.
metropolitan area for more than 37 years. In November 1995, the Company
announced a strategic alliance with a wholly-owned subsidiary of Security
Capital U.S. Realty (together with Security Capital U.S. Realty, "SC-USREALTY"),
a European real estate operating company which owns strategic positions in
selected real estate companies in the United States. As of December 31, 1999,
SC-USREALTY owned approximately 42.8% of the outstanding common stock of the
Company.

         In addition to its real estate and development activities, the Company
conducts an executive suites business through its affiliates HQ Global
Workplaces, Inc. ("HQ Global"), OmniOffices (UK) Limited ("Omni UK"), and
OmniOffices (Lux) 1929 Holding Company S.A. ("LUX"). On January 20, 2000, the
Company, HQ Global, VANTAS Incorporated ("VANTAS") and Reckson Service
Industries, Inc. d/b/a FrontLine Capital Group ("FrontLine Capital Group")
entered into several agreements pursuant to which a series of transactions will
occur, including (i) the merger of VANTAS with and into HQ Global, (ii) the
acquisition by FrontLine Capital Group of certain shares of common stock of HQ
Global from the Company and other stockholders of HQ Global, and (iii) the
acquisition by HQ Global from the Company of the Company's debt and equity
interests in Omni UK and LUX. Following the completion of these transactions,
FrontLine Capital Group will own a substantial majority of the outstanding stock
of HQ Global, with the Company retaining a minority interest in HQ Global. The
results of the executive suites business are reported as a discontinued
operation.

         The Company's experienced staff of over 1,900 employees, including
approximately 450 on-site building employees and approximately 1,200 persons
employed by its executive suite affiliates, provides a broad range of real
estate services. The Company's principal executive offices are located at 1850 K
Street, N.W., Washington, D.C. 20006 and its telephone number is (202) 729-7500.
The Company's web site can be found at www.carramerica.com. The Company was
organized as a Maryland corporation on July 9, 1992.


Business Strategy

         The Company's primary business objectives are to achieve long-term
sustainable per share cash flow growth and to maximize stockholder value through
a strategy of (i) acquiring, developing, owning and operating office properties
primarily in markets throughout the United States that exhibit strong, long-term
growth characteristics and (ii) maintaining and enhancing a national operating
system that provides corporate users of office space with a mix of products and
services to meet their workplace needs at both the national and local level.

         The Company's major segments of continuing operations include real
estate property operations and development operations (conducted directly and
through its affiliate CarrAmerica Development, Inc.). Real estate property
operations includes the ownership of commercial real estate. Such operations
comprise approximately 97% of the Company's revenues from continuing operations
and approximately 92% of the Company's assets (including assets held by
CarrAmerica Development, Inc.). Development operations include

                                       1
<PAGE>

the development of office space and the buildout of tenant space. The Company's
investment in this business represents approximately 7% of the Company's assets
(including assets held by CarrAmerica Development, Inc.) and 1% of the Company's
revenues from continuing operations.

Real Estate Property Operations

         Core Markets. The Company has focused its acquisition and development
activity in U.S. markets which generally possess strong long-term growth
characteristics. Within these markets, the Company targets specific submarkets
in which (i) operating costs for businesses are relatively low, (ii) long-term
population and job growth generally are expected to exceed the national average,
(iii) large, well-educated employment pools exist, and (iv) barriers to entry
exist for new supplies of office space. The Company has established a local
presence in each of its existing core markets through its investment activity
and through relationships established by its experienced Market Managing
Directors. The Company's core markets include the following: Atlanta, Austin,
Chicago, Dallas, Denver, Boca Raton, Florida, Orange County/Los Angeles,
Phoenix, Portland, Oregon, Salt Lake City, San Diego, San Francisco Bay Area,
Seattle and metropolitan Washington, D.C.

         For each identified core market, the Company has established a set of
general guidelines and physical characteristics to evaluate investment
opportunities. All investment decisions are driven by real estate research,
focusing on variables such as composition of economic base rate, and composition
of job growth and office space supply and demand fundamentals.

         As of December 31, 1999 the distribution of the Company's real estate
property operations (on a rentable square foot basis) was as follows: 41% in its
Pacific region, primarily in Seattle and the California markets of Silicon
Valley, Pleasanton, San Mateo, Orange County, Los Angeles and San Diego; 24% in
its Southeast region, primarily in metropolitan Washington, D.C., Atlanta and
Boca Raton, Florida; 13% in its Mountain region, primarily in Salt Lake City,
Denver and Phoenix; and 22% in its Central region, primarily in Chicago, Dallas
and Austin.

         Operating Property Acquisitions. In November 1995, the Company
implemented a major initiative to acquire operating office properties in order
to establish the operating platform for its national business strategy. Between
January 1, 1996 and October 31, 1998, the Company acquired 302 operating
properties containing approximately 20.3 million square feet, resulting in an
approximate 550% increase in the total square footage of operating properties in
which the Company has a majority interest. These properties were acquired for an
aggregate purchase price of approximately $2.5 billion. Since October 1998, the
Company has not been focused on acquisitions as a catalyst for growth.

         National Operating System. As part of its business strategy, the
Company has developed and will continue to enhance a national operating system
to provide nationally coordinated customer service, marketing and development.
The Company's national operating system consists of three components: (i) a
Market Managing Director Group, currently consisting of 10 Market Managing
Directors focused on developing and maintaining strong local relationships with
the Company's customers and the brokerage community and identifying investment
opportunities for the Company; (ii) a National Services Group, which is
dedicated to marketing the Company's office space to a targeted list of
companies; and (iii) a National Development Group, conducted through an
affiliate, which is responsible for managing the development of office
properties, build-to-suit facilities and business parks. The Company's national
operating system is designed to provide corporate users of office space with a
mix of products and services to meet their workplace needs at both the national
and local levels. The Company believes that through its existing portfolio of
operating properties, property development opportunities and land acquired and
currently held for future development, the Company can generate incremental
demand through the relocation and expansion needs of many of its customers, both
within a single core market and in multiple core markets.

                                       2
<PAGE>

      Market Managing Director Group. The Market Managing Director Group
currently consists of 10 Market Managing Directors who cover the 14 core markets
in which the Company currently owns properties. These Market Managing Directors
are responsible for maximizing the performance of the Company's properties in
their markets and ensuring that the needs of the Company's customers are
consistently being met. Because they meet with the Company's customers on a
regular basis, Market Managing Directors are cognizant of and responsive to
customers' relocation or expansion needs. The Market Managing Directors have
extensive knowledge of local conditions in their respective markets and,
therefore, are invaluable in identifying attractive investment opportunities in
their markets. In addition, through their contact with customers, Market
Managing Directors are well positioned to help the National Services Group
identify customers with new build-to-suit and multi-market requirements.

         National Services Group. The Company established the National Services
Group in 1997. This group is responsible for marketing the Company's properties,
build-to-suit capabilities and the national scope of the Company's operations to
a targeted list of major corporate users. The National Services Group acts as a
primary point of contact for national customers, coordinating all of the office
space the Company offers and giving corporate customers the opportunity to
address their national space requirements efficiently and economically.

         National Development Group. The National Development Group is
responsible for developing office properties, build-to-suit facilities and
business parks. These operations are handled by the Company's affiliate,
CarrAmerica Development, Inc. ("CarrAmerica Development"), which has a
development team of over 40 professionals consisting of architects, engineers
and construction professionals located across the United States who have an
average of over 15 years of experience developing office properties. This team
of development professionals oversees every aspect of land planning, building
design, construction and development of office properties, ensuring that all
projects meet the same high standards and uniform specifications in building
design and systems. The Company believes that the National Development Group's
expertise has given the Company a competitive edge in marketing its facilities
and services to customers.

         Innovative Strategic Alliances. An increasingly important component of
the Company's business strategy involves establishing alliances with service
providers that offer the Company new opportunities to build value for its
customers and its stockholders. In 1999, the Company entered into two such
alliances. First, the Company joined with other real estate companies to form
Broadband Office, Inc., which provides telecommunications and technology
services to office buildings throughout the country. By contributing access to
its property portfolio, the Company expects to benefit from its ability to
improve choice and service for its customers, as well as from an equity position
in the company. In December 1999, the Company also entered into an alliance with
DukeSolutions, a Duke Energy subsidiary, to implement a comprehensive energy
management program that pioneers creative web-based energy management
strategies. The Company believes that this alliance will significantly reduce
energy costs for its customers.

         Asset Optimization. As a component of its business strategy, the
Company may dispose of assets that become inconsistent with its long-term
strategic or return objectives or where market conditions for disposition are
favorable. The Company then redeploys the proceeds of dispositions into other
office properties, the funding of development operations, or in support of other
general corporate needs. Consistent with this strategy, the Company disposed of
63 properties during 1999, containing approximately 3.8 million square feet for
approximately $500 million. The Company recognized a gain of $54.8 million in
conjunction with these transactions. The Company also may consider disposing of
additional properties or interests in properties, some of which may be
significant. The Company, however, has agreed with SC-USREALTY to use its
reasonable efforts to dispose of properties through tax-deferred exchanges (and
the Company also is subject to other similar restrictions with respect to
certain properties owned by the Company's subsidiaries CarrAmerica Realty, L.P.
and Carr Realty, L.P.), which may limit its flexibility in effecting
dispositions. In addition, tax laws applicable to REITs restrict the Company's
ability to dispose of certain properties.

                                       3

Development Operations

         Development of office properties is an important component of the
Company's growth strategy as attractive acquisition opportunities diminish due
to the influx of capital into the office property market. The Company believes
that long-term investment returns resulting from properties it develops
generally will exceed those from properties it acquires, without the assumption
of significantly increased investment risks. The Company minimizes its
development risk by employing, through CarrAmerica Development, extensively
trained and experienced development personnel, by avoiding the assumption of
entitlement risk in conjunction with land acquisitions and by entering into
guaranteed maximum price (GMP) construction contracts with seasoned and credible
contractors. Most importantly, the Company carefully analyzes the supply and
demand characteristics of a core market before commencing inventory development
in the market. In general, the Company will only undertake inventory development
(which excludes properties under construction that have been substantially
pre-leased) in markets with strong real estate fundamentals, and then the
Company generally will construct office buildings attractive to a wide range of
office users. The Company's research-driven development program enables it to
tailor its development activities in each core market, from inventory
development, build-to-suit projects, and holding land for future development.
During 1999, the Company placed in service approximately 3.3 million square feet
of office properties. The total cost of these development projects was
approximately $530 million and the Company expects that the first year
stabilized unleveraged return of this square footage will be 11.4%. As of
December 31, 1999, the Company (including CarrAmerica Development) had
approximately 1.3 million square feet of office space in 22 development projects
underway which are expected to require a total investment by the Company of
approximately $200.1 million. As of December 31, 1999, $116.0 million, or 58.0%
of the total expected investment, had been expended.

         The Company also believes that having a significant land inventory to
support future development provides it with a competitive advantage in
responding to customers' needs for office space in markets with low vacancy
rates, barriers to entry for new supplies of office space and increasing rental
rates. In addition to its portfolio of operating properties and projects
currently under development, the Company owned or controlled, as of December 31,
1999, land in 10 of its core markets that is expected to support future
development of up to 4.5 million square feet of office space.

         The Company is engaged in the real estate development business directly
and through its affiliate CarrAmerica Development. As of December 31, 1999, the
Company's total investment in CarrAmerica Development was approximately $233.8
million, $26.8 million of which was in the form of an equity investment, $121.5
million of which was in the form of unsecured debt and $85.5 million was in the
form of secured debt.

         In order to comply with tax laws applicable to REITs, the Company owns
approximately 95% of the economic interest of CarrAmerica Development, but owns
less than 10% of the voting stock of CarrAmerica Development. Substantially all
of the voting stock of CarrAmerica Development (representing approximately 5% of
the economic interest) is owned by The Oliver Carr Company. Because the Company
does not own a significant portion of the voting stock of CarrAmerica
Development, there are certain risks associated with the Company's investments
in this company. See "Risk Factors -- Our Business Structure Has Certain Risks
Associated With It - Lack of Voting Control Over Some of Our Affiliates."

Acquisitions and Development

         During 1999 the Company acquired 5 operating properties and land held
for future development for approximately $47.2 million. The operating properties
contain approximately 205,000 square feet and the land is expected to support
the development of approximately 376,000 square feet of office space. Also
during 1999, the Company developed and placed into service approximately 3.3
million square feet of office space and placed under construction approximately
826,000 square feet of office space.


Discontinued Operations

         The executive suites business (HQ Global, OMNI UK, and LUX) typically
involves leasing 20,000 to 30,000 square feet of an office building from an
owner and outfitting that space with 60 to 70 individual offices (known as
office suites) that are leased on a relatively short-term basis (i.e., one year
or less) to customers who

                                       4
<PAGE>

 generally utilize one to three offices at a time. Customers are provided with a
wide array of services, including administrative support services (e.g.,
secretarial, duplicating, fax and receptionist services), conference and
training facilities, video conferencing, travel arrangements and catering
arrangements.

         The Company currently owns approximately 95% of the economic interest
of HQ Global, Omni UK and LUX, but owns none of the voting stock of these
companies. The voting stock of HQ Global (representing approximately 5% of the
economic interest) is owned by a limited liability company in which certain
current and former executive officers of the Company and HQ Global are members,
SC-USREALTY and The Oliver Carr Company. Substantially all of the voting stock
of Omni UK and LUX (representing approximately 5% of the economic interest) is
owned by HQ Global. Because the Company does not own any of the voting stock of
these companies, there are certain risks associated with the Company's
investments in these companies. See "Risk Factors -- Our Business Structure Has
Certain Risks Associated With It - Lack of Voting Control Over Some of Our
Affiliates."

         On January 20, 2000, the Company, HQ Global, VANTAS and FrontLine
Capital Group entered into several agreements pursuant to which a series of
transactions will occur, including (i) the merger of VANTAS with and into HQ
Global, (ii) the acquisition by FrontLine Capital Group of certain shares of
common stock of HQ Global from the Company and other stockholders of HQ Global,
and (iii) the acquisition by HQ Global from the Company of the Company's debt
and equity interests in Omni UK and Lux. Following the completion of these
transactions, FrontLine Capital Group will own a substantial majority of the
outstanding stock of HQ Global, with the Company retaining a minority interest
in HQ Global. It is anticipated that CarrAmerica's retained minority interest in
HQ Global will be accounted for using the cost method of accounting following
the transaction. The anticipated gain at closing will be included in
Discontinued Operations net of transaction costs.

         In connection with the HQ Global/VANTAS transaction, it is contemplated
that CarrAmerica will enter into various agreements at closing, including (i) a
stockholders agreement, which will provide CarrAmerica with certain rights with
respect to its ongoing equity interest in HQ Global, and will impose certain
obligations on CarrAmerica in connection therewith, and (ii) an indemnification
and escrow agreement which will provide CarrAmerica with certain rights in the
event certain representations and warranties regarding the operations of VANTAS
turn out to be incorrect (subject to a number of limitations), and will impose
certain obligations on CarrAmerica in the event certain representations and
warranties regarding the operations of HQ Global, HQ UK or LUX turn out to be
incorrect (subject to a number of limitations). In connection with these
indemnity obligations, CarrAmerica has agreed to indemnify FrontLine Capital
Group and certain existing directors of HQ Global against any losses incurred in
connection with the pending litigation involving two minority stockholders of HQ
Global referred to in Item 3 below.

         If the proposed transactions are consummated, certain limitations will
be imposed on the continuing HQ Global enterprise to help avoid jeopardizing the
Company's status as a real estate investment trust. First, HQ Global will agree
to elect to be treated as a "taxable REIT subsidiary" under the Internal Revenue
Code so long as the Company continues to be taxed as a REIT and retains a
threshold interest in HQ Global. Second, through January 1, 2001, HQ Global will
not engage in various transactions that would result in the Company owning more
than 10% of the voting securities of HQ Global. Third, through July 2002, HQ
Global will not engage in certain transactions that would cause the Company to
fail to meet one of the asset tests applicable to REITs. Finally, HQ Global will
agree not to undertake any transaction that would result in recognition by the
Company of more than $25 million of taxable income or gain in 2000 (other than
the transaction contemplated by the merger agreement) or more than $75 million
of taxable income or gain in 2001. HQ Global also will agree to provide advance
notice of transactions that would trigger a significant amount of gain for the
Company through 2003.

         Closing of the VANTAS transaction is scheduled to occur on or prior to
April 30, 2000. The proposed transaction is subject to satisfaction of a number
of conditions. There can be no assurance that the proposed transaction will be
consummated.

Financing Activity

         In April 1998, the Company sold 5,000,000 shares of common stock to
Merrill Lynch, Pierce, Fenner & Smith Incorporated ("Merrill Lynch"), resulting
in net proceeds of approximately $147 million, in what is commonly known as a
"forward equity sale" transaction. In connection with that transaction, the
Company entered into an agreement with Merrill Lynch under which the parties
agreed to adjust the number of shares of common stock issued to Merrill Lynch
(or the aggregate purchase price paid for such shares) based upon the proceeds
received by Merrill Lynch upon a resale of the shares in April 1999 in relation
to the amount originally paid by Merrill Lynch ($150 million), plus a forward
accretion component and less dividends paid on the shares. The Company settled
this agreement with cash payments in October 1998 and March 1999, and the
5,000,000 shares were returned to the Company and cancelled.

         The Company and one of its affiliates entered into a joint venture with
J.P. Morgan & Co. to purchase and develop 1201 F Street in downtown Washington,
D.C. J.P. Morgan & Co. has become a 65% joint venture partner in the partnership
that owns the property and has committed to provide its pro-rata share of the
required expected capital of $71.8 million. In addition, Bank of America and
Mass Mutual have provided or agreed to provide construction financing and
permanent financing for this project.

         In March 1999, the Company closed on a refinancing of the loans secured
by 1255 23rd Street, 1730 Pennsylvania Avenue and International Square
properties, all of which are located in downtown Washington, D.C., which
refinancing increased the aggregate principal amount of the loan by $41.1
million to approximately $222.0 million, extended the term approximately six
years and adjusted the interest rates to one global fixed interest rate of
8.12%. In July 1999, the Company replaced the mortgage on 1775 Pennsylvania
Avenue in downtown Washington, D.C. with a $12.0 million, 10-year loan which
will bear interest at a fixed rate of 7.63% which resulted in net proceeds to
the Company of $6.0 million.

         In addition, during the second quarter of 1999, the Company refinanced
one loan totaling $15.0 million at a rate of 7.13% secured by two properties
located in Orange County, California, which resulted in net proceeds to the
Company of $4.9 million.

Directors of the Company

         The directors of the Company are divided into three classes, with
approximately one-third of the directors elected by the stockholders annually.
The Board of Directors of the Company currently consists of the following
persons:

         Oliver T. Carr, Jr., 74, has been Chairman of the Board of Directors of

Risk Factors

     In addition to the other information in this document, you should consider
carefully the following risk factors in evaluating an investment in our
securities.

Our Performance is Subject to Risks Associated with Real Estate Investment

     We are a real estate company that derives most of its income from the
ownership and operation of office buildings. There are a number of factors that
may adversely affect the income that our properties generate, including the
following:

     Economic Downturns. Downturns in the national economy, or in regions or
localities where our properties are located, generally will negatively impact
the demand for office space.

     Oversupply of Office Space. An oversupply of space in markets where we own
office properties making it more difficult for us to lease space at attractive
rental rates would typically cause rental rates and occupancies to decline.

     Competitive Properties. If our properties are not as attractive to tenants
(in terms of rents, services or location) as other properties that are
competitive with ours, we will lose tenants to those properties, or could have
to reduce our rental rates to compensate for that disparity.

     Renovation Costs. In order to maintain the quality of our office buildings
and successfully compete against other properties, we periodically have to spend
money to repair and renovate our properties.

     Tenant Risk. Our performance depends on our ability to collect rent from
our tenants. While no tenant in our portfolio accounted for more than 5% of our
rental revenue as of December 31, 1999, the Company's financial position may be
adversely affected by financial difficulties experienced by a major tenant, or
by a number of smaller tenants, including bankruptcies, insolvencies or general
downturns in business.

     Reletting Costs. As leases expire, we try to either relet the space to an
existing tenant or attract a new tenant to occupy the space. In either case, we
likely will incur significant costs in the process. In addition, if market rents
have declined since the time the expiring lease was entered into, the terms of
any new lease signed likely will not be as favorable to us as the terms of the
expiring lease, thereby reducing the income earned from that space.

     Regulatory Costs. There are a number of government regulations, including
zoning and tax laws, that apply to the ownership and operation of office
buildings. Compliance with existing and newly adopted regulations often requires
us to spend a significant amount of money on our properties.

     Fixed Nature of Costs. Most of the costs associated with owning and
operating an office building are not necessarily reduced when circumstances such
as market factors and competition cause a reduction in income from the property.

     Environmental Problems Are Possible and Can Be Costly. Federal, state and
local laws and regulations relating to the protection of the environment may
require a current or previous owner or operator of real property to investigate
and clean up hazardous or toxic substances or petroleum product releases at the
property. The presence of or failure to clean up contamination may adversely
affect our ability to sell or lease a property or to borrow using a property as
collateral.

     Competition. A number of other major real estate investors with significant
capital compete with us. These competitors include publicly traded REITs,
private REITs, investment banking firms and private institutional investment
funds.

New Developments and Acquisitions May Fail to Perform As Expected

     Over the last few years, we have embarked on a major acquisition and
development program. In deciding whether to acquire or develop a particular
property, we made certain assumptions regarding the expected future performance
of that property. If a number of these new properties do not perform as
expected, our financial performance will be adversely affected.

     While our acquisition pace has declined significantly, we remain very
active in developing office properties. New office property developments are
subject to a number of risks, including construction delays, complications in
obtaining necessary zoning, occupancy and other governmental permits, cost
overruns, financing risks, and the possible inability to meet expected occupancy
and rent levels. If any of these problems occur, development costs for a project
will increase, and there may be costs incurred for projects that are not
completed.

Our Use of Debt Subjects Us to Various Financing Risks

     While we believe that we have a conservative borrowing policy, we do
regularly borrow money to finance our business, particularly the acquisition and
development of properties. We generally incur unsecured debt, although in many
cases we will incur mortgage debt that is secured by one or more of our office
buildings. There are certain risks inherent in borrowing money, including the
following:

     No Limitation on Debt Incurrence. The Company's organizational documents do
not limit the amount of debt the Company can incur. The degree of leverage of
the Company could have important consequences, including making it more
difficult for us to obtain additional financing in the future for business
needs, as well as making us more vulnerable to an economic downturn.

     Possible Inability to Meet Scheduled Debt Payments. If our properties do
not perform as expected, our cash flow from our properties may not be enough to
make required principal and interest payments. If a property is mortgaged to
secure payment of indebtedness and we are unable to meet mortgage payments, the
holder of the mortgage or lender could foreclose on the property, resulting in
loss of income and asset value. An unsecured lender could also attempt to
foreclose on some of the Company's assets in order to receive payment.

     Inability to Refinance Debt. In almost every case, very little of the
principal amount that we borrow is repaid prior to the maturity of the loan. We
generally expect to refinance that debt when it matures, although in some cases
we may pay off the loan. If principal amounts due at maturity cannot be
refinanced, extended or paid with proceeds of other capital transactions, such
as new equity capital, our cash flow will be insufficient in all years to repay
all maturing debt. Prevailing interest rates or other factors at the time of a
refinancing (such as possible reluctance of lenders to make commercial real
estate loans) may result in higher interest rates and increased interest
expense.

     Financial Covenants Could Adversely Affect Our Financial Condition. The
Company's credit facilities and the indentures under which the Company's senior
unsecured indebtedness is issued contain financial and operating covenants,
including coverage ratios and other limitations on the Company's ability to
incur secured and unsecured indebtedness, sell all or substantially all of its
assets and engage in mergers, consolidations and certain acquisitions. These
covenants may restrict the Company's ability to engage in transactions that
would otherwise be in the Company's best interests.

Our Business Structure Has Certain Risks Associated With It

     A Major Stockholder Has Influence on Our Operations. SC-USREALTY owned
approximately 42.8% of the outstanding shares of our common stock as of December
31, 1999. No other stockholder is permitted to own more than 5% of our common
stock, subject to certain exceptions. Under a Stockholders Agreement with the
Company, SC-USREALTY has the right to nominate up to 40% of the directors. The
Stockholders Agreement also gives SC-USREALTY certain rights that limit our
ability to take certain actions and limits our ability to engage in certain
transactions that may be in the short-term best interests of other stockholders.
This situation results in SC-USREALTY having a substantial influence over the
affairs of the Company. This could potentially be disadvantageous to other
stockholders' interests, which may not converge with the interests of SC-
USREALTY.

     Certain Officers and Directors May Have Interests that Conflict with the
Interests of Stockholders. Certain officers and members of the board of
directors of the Company own units of limited partner interest in Carr Realty,
L.P., a partnership that owns some of the Company's properties. These
individuals may have personal interests that conflict with the interests of the
Company's stockholders with respect to business decisions affecting the Company
and Carr Realty, L.P., such as interests in the timing and pricing of property
sales or refinancings in order to obtain favorable tax treatment. The Company,
as the sole general partner of Carr Realty, L.P., has the exclusive authority to
determine whether and on what terms the partnership will sell or refinance an
individual property, but the effect of certain transactions on these unitholders
may influence decisions affecting these properties.

     We May Not Be Able to Sell Properties When Appropriate. Real estate
property investments generally cannot be sold quickly. In addition, the tax laws
applicable to REITs restrict our ability to dispose of certain properties.
Therefore, we may by unable to vary our portfolio promptly in response to market
conditions, which may adversely affect our financial position.

     Lack of Voting Control Over Some of Our Affiliates. While most of our
income is generated from the ownership and operation of our office buildings, we
own nonvoting interests in five affiliates that either currently produce or are
expected in the future to produce significant contributions to our income. Carr
Services, Inc. conducts management and leasing operations for third parties and
for office buildings in which we own less than a 100% interest. CarrAmerica
Development conducts fee-based development services for the Company and for
third parties. HQ Global, Omni UK and LUX are engaged in the executive suites
business, providing short-term office space together with telephone answering,
data processing and other office support services. As of December 31, 1999, the
Company owned approximately 95% of the economic interest in each of these
companies through the ownership of nonvoting common stock. The voting stock of
each of these companies is owned by certain entities and individuals that have
some affiliation with the Company (or, in the case of Omni UK and LUX, by HQ
Global).

     The Company owns nonvoting stock in these companies because the tax laws
applicable to REITs currently prohibit the Company from owning more than a 10%
voting interest. As a result, the Company has no right to elect the directors of
these companies, and its ability to influence their operations is limited. These
companies may engage in business activities that are not in the Company's best
interests.

     We Depend On External Capital. To qualify as a REIT, we generally must
distribute to our stockholders each year at least 95% of our net taxable income.
Because of these distribution requirements, we likely will not be able to fund
all future capital needs, including capital for property development and
acquisitions, with income from operations. We therefore will have to rely on
third-party sources of capital, which may or may not be available on favorable
terms, if at all. Our access to third-party sources of capital depends on a
number of things, including the market's perception of our growth potential and
our current and potential future earnings.

                                       15
<PAGE>

Certain Factors May Inhibit Changes in Control of the Company

     Charter and By-law Provisions. Certain provisions of our charter and by-
laws may delay or prevent a change in control of the Company or other
transactions that could provide our common stockholders with a premium over the
then-prevailing market price of their common stock or that might otherwise be in
the best interests of our stockholders. These include a staggered board of
directors and the ability of our board of directors to authorize the issuance of
preferred stock without stockholder approval. Also, any future series of
preferred stock may have voting provisions that could delay or prevent a change
in control or other transaction that might involve a premium price or otherwise
be in the best interests of our stockholders.

     Ownership Limit. In order to assist the Company in maintaining its
qualification as a REIT, the Company's charter contains certain provisions
generally limiting the ownership of shares of capital stock by any single
stockholder to 5% of the Company's outstanding common stock and/or 5% of any
class or series of preferred stock. The federal tax laws include complex stock
ownership and attribution rules that apply in determining whether a stockholder
exceeds the ownership limits. These rules may cause a stockholder to be treated
as owning stock that is actually owned by others, including family members and
entities in which the stockholder has an ownership interest. The board of
directors of the Company could waive this restriction if it were satisfied that
ownership in excess of these ownership limits would not jeopardize our status as
a REIT and the board otherwise decided that a waiver would be in the Company's
interests. Capital stock acquired or transferred in breach of the ownership
limit will be automatically transferred to a trust for the benefit of a
designated charitable beneficiary.

     Maryland Law Provisions. Certain provisions of Maryland law applicable to
the Company because it is a Maryland corporation prohibit "business
combinations" with any person that beneficially owns ten percent or more of the
outstanding voting shares of the Company (an "interested stockholder") or with
an affiliate of the interested stockholder. These prohibitions last for five
years after the most recent date on which the person became an interested
stockholder. After the five-year period, a business combination with an
interested stockholder must be approved by two super-majority stockholder votes
unless, among other conditions, the Company's common stockholders receive a
minimum price for their shares and the consideration is received in cash or in
the same form as previously paid by the interested stockholder for its common
shares. The Company's board of directors has opted out of these business
combination provisions. Consequently, the five-year prohibition and the super-
majority vote requirements will not apply to a business combination involving
the Company. The Company's board of directors may, however, repeal this election
in most cases and cause the Company to become subject to these provisions in the
future. Being subject to the provisions could delay or prevent a change in
control or other transaction involving the Company that might involve a premium
price or otherwise be in the best interests of the Company's stockholders.

The Market Value of Our Securities Can Be Adversely Affected by Many Factors

     As with any public company, a number of factors may adversely influence the
public market price of our common stock, many of which are beyond our control.
These factors include: the level of institutional interest in the Company; the
perception of REITs generally, and REITs with portfolios similar to ours in
particular, by market professionals, and the attractiveness of securities of
REITs in comparison to other companies; our financial condition and performance,
and the market's perception of our growth potential and potential future cash
dividends; increases in market interest rates, which may lead investors to
demand a higher annual yield from distributions by the Company in relation to
the price paid for our stock; and the relatively low trading volume of shares of
REITs in general, which tends to exacerbate a market trend with respect to our
stock.

     Sales of a substantial number of shares of our stock, or the perception
that such sales could occur, also could adversely affect prevailing market
prices for our stock. In addition to the possibility that we may sell shares of
our stock in a public offering at any time, we also may issue shares of common
stock upon redemption of units of interest held by third parties in affiliated
partnerships that we control, as well as upon exercise of stock options that we
grant to our employees and others. All of these shares will be available for
sale in the public markets from time to time. In addition, SC-USREALTY, our
largest stockholder (owning more than one-third of our shares) has the right to
sell its shares at any time, pursuant to registration rights granted to it in
connection with its original investment in the Company.

                                       16

Our Status As a REIT

     We believe that the Company qualifies for taxation as a REIT for federal
income tax purposes, and we plan to operate so that the Company continues to
meet the requirements for taxation as a REIT. If we qualify as a REIT, we
generally will not be subject to federal income tax on our income that we
distribute currently to our shareholders. Many of the REIT requirements,
however, are highly technical and complex. The determination that the Company is
a REIT requires an analysis of various factual matters and circumstances that
may not be totally within our control. For example, to qualify as a REIT, at
least 95% of our gross income must come from specific passive sources, like
rent, that are itemized in the REIT tax laws. We also are required to distribute
to our stockholders at least 95% of our REIT taxable income (excluding capital
gains). The distribution requirements will be reduced to 90% for taxable years
after December 31, 2000. The fact that we hold certain of our assets through
partnerships and their subsidiaries further complicates the application of the
REIT requirements. Even a technical or inadvertent mistake could jeopardize the
Company's REIT status. Furthermore, Congress and the IRS might make changes to
the tax laws and regulations, and the courts might issue new rulings, that make
it more difficult, or impossible, for us to remain qualified as a REIT.

     If the Company fails to qualify as a REIT, it would be subject to federal
income tax at regular corporate rates. Also, unless the IRS granted the Company
relief under certain statutory provisions, it would remain disqualified as a
REIT for four years following the year it first failed to qualify. If the
Company failed to qualify as a REIT, we would have to pay significant income
taxes. This likely would have a significant adverse affect on the value of our
securities. In addition, we would no longer be required to pay any dividends to
stockholders.

     Even if we qualify as a REIT, we are required to pay certain federal, state
and local taxes on our income and property. For example, if the Company has net
income from "prohibited transactions," that income will be subject to a 100%
tax. In general, prohibited transactions are sales or other dispositions of
property held primarily for sale to customers in the ordinary course of
business. The determination as to whether a particular sale is a prohibited
transaction depends on the facts and circumstances related to that sale. While
we have recently undertaken a significant number of asset sales, we do not
believe that those sales should be considered prohibited transactions, but there
can be no assurance that the IRS would not contend otherwise. In addition, any
net taxable income earned directly by some of our affiliates, including HQ
Global, Carr Services, Inc. and CarrAmerica Development, Inc., is subject to
federal and state corporate income tax. Similarly, the income of our affiliates,
Omni UK and LUX, is subject to some foreign taxes.

     Currently, a REIT may not own securities in any one issuer if the value of
those securities exceeds 5% of the value of the REIT's total assets or the
securities owned by the REIT represent more than 10% of the issuer's outstanding
voting securities. As a result of the Work Incentives Improvement Act, after
December 31, 2000, the 5% value test and the 10% voting security test will be
modified in two respects. First, the 10% voting securities test will be expanded
so that REITs also will be prohibited from owning more than 10% of the value of
the outstanding securities of any one issuer. Second, an exception to these
tests will allow a REIT to own securities of a subsidiary that exceed the 5%
value test and the new 10% vote or value test if the subsidiary elects to be a
"taxable REIT subsidiary." The expanded 10% vote or value test, however, will
not apply to an existing subsidiary unless it engages in a substantial new line
of business or acquires any substantial asset or the Company acquires any
securities in that subsidiary after July 12, 1999. Under a new asset test, for
taxable years beginning after December 31, 2000, the Company will not be able to
own securities of taxable REIT subsidiaries that represent in the aggregate more
than 20% of the value of the Company's total assets.

     Several provisions of the new law will ensure that a taxable REIT
subsidiary will be subject to an appropriate level of federal income taxation.
For example, a taxable REIT subsidiary will be limited in its ability to deduct
interest payments made to an affiliated REIT. In addition, the REIT will have to
pay a 100% penalty tax on some payments that it receives if the economic
arrangements between the REIT, the REIT's tenants, and the taxable REIT
subsidiary are not comparable to similar arrangements between unrelated parties.

     The Company currently owns more than 10% of the total value of the
outstanding securities of HQ Global, Carr Services, Inc., CarrAmerica
Development, Omni UK and LUX. As part of the transaction in which FrontLine
Capital Group will acquire a majority interest in HQ Global, HQ Global will
elect to be treated as a taxable REIT subsidiary and the Company's direct
interests in Omni UK and LUX will be terminated. Carr Services, Inc. and
CarrAmerica Development also are likely to elect to be taxable REIT
subsidiaries. The

                                       17
<PAGE>

provisions described above likely will have the effect of increasing the federal
income tax expenses of these entities.

Our Company Is Not a Suitable Investment for Foreign Investors

     Our charter contains provisions generally preventing foreign investors
(other than SC-USREALTY and its affiliates) from acquiring additional shares of
the Company's capital stock if the acquisition would cause us to fail to quality
as a domestically controlled REIT under the federal tax code. The application of
such provisions could prevent a foreign investor from acquiring stock or cause
stock that has been acquired to be reacquired automatically from the foreign
investor by a designated charitable trust. Accordingly, acquisition of our
capital stock would not likely be a suitable investment for foreign investors
other than SC-USREALTY.

Item 2.  PROPERTIES

     General. As of December 31, 1999, the Company owned interests (consisting
of whole or partial ownership interests) in 275 operating office properties
located in 14 core markets across the United States. As of December 31, 1999,
the Company owned fee simple title or leasehold interest in 269 operating office
properties, controlling partial interests in two operating office properties,
and non-controlling partial interests of 5% to 50% in four operating office
properties. In addition, as of December 31, 1999, the Company owned (either
directly or through CarrAmerica Development) 22 office properties under
development. Except as disclosed in "Item 7. Management's Discussion and
Analysis of Financial Condition and Results of Operations - Liquidity and
Capital Resources," the Company has no immediate plans to renovate its operating
office properties other than for routine capital maintenance. The Company
believes its properties are adequately covered by insurance. The Company
believes that, as a result of its national operating system, market research
capabilities, access to capital, and experience as an owner, operator and
developer of office properties, it will continue to be able to identify and
consummate acquisition and development opportunities and to operate its
portfolio more effectively than competitors without such capabilities. The
Company, however, competes in many of its core markets with other real estate
operators, some of which may have been active in such markets for a longer
period than the Company.

Item 3.  LEGAL PROCEEDINGS


         The Company currently is involved in litigation with two stockholders
of HQ Global Workplaces, Inc. involving the conversion in September 1998 of
approximately $111 million of debt previously loaned by the Company to HQ Global
into stock of HQ Global. The Company and HQ Global initiated this litigation by
filing a complaint seeking a declaratory judgment that the terms of the debt
conversion were fair, after these two stockholders threatened to challenge the
terms of the conversion, claiming that the conversion price utilized, and the
methods by which the conversion price was agreed upon between the Company and HQ
Global, were not fair to HQ Global or these stockholders. The two stockholders
filed counterclaims against the Company, HQ Global and the board of directors of
HQ Global seeking a judgment declaring the conversion void or voidable, or in
the alternative compensatory and punitive damages.

         Although the Company believes that the two stockholders' claims are
without merit and that it and HQ Global will ultimately prevail in their actions
against the two stockholders, there can be no assurance that the court will not
find the conversion price to have been unfair and declare the conversion void,
which would have the effect of diluting the Company's equity interest in HQ
Global or award the two stockholders compensatory and punitive damages. However,
even if the two stockholders were successful in their claims, the Company does
not believe that such a result would have a material adverse effect on the
financial condition or results of operations of the Company or HQ Global.

         The Company is party to a variety of other legal proceedings arising in
the ordinary course of its business. All of these other matters, taken together,
are not expected to have a material adverse impact on the Company.


Item 4.  Submission of Matters to a Vote of Security Holders

Item 5.  Market for Registrant's Common Equity & Related Stockholder Matters

         The Company's common stock is listed on the New York Stock Exchange
("NYSE") under the symbol "CRE". As of December 31, 1999, there were 525
stockholders of record. The following table sets forth the high and low sale
prices of the Company's common stock as reported on the NYSE Composite Tape, and
the dividends per share of common stock paid for each full quarterly period
within the two most recent fiscal years:


         1999              1Q          2Q         3Q        4Q         Full Year

         The Company, in order to qualify as a REIT, is required to make
distributions (other than capital gain distributions) to its stockholders in
amounts at least equal to (i) the sum of (A) 95% of its "REIT taxable income"
(computed without regard to the dividends paid deduction and its net capital
gain) and (B) 95% of the net income (after tax), if any, from foreclosure
property, minus (ii) the sum of certain items of non-cash income. The Company's
distribution strategy is to distribute what it believes is a conservative
percentage of its cash flow permitting the Company to retain funds for capital
improvements and other investments while funding its distributions.

         For federal income tax purposes, distributions may consist of ordinary
income, capital gains, nontaxable return of capital or a combination thereof.
Distributions that exceed the Company's current and accumulated

                                       28
<PAGE>

earnings and profits (calculated for tax purposes) constitute a return of
capital rather than a dividend and reduce the stockholder's basis in his or her
shares of common stock. To the extent that a distribution exceeds both current
and accumulated earnings and profits and the stockholder's basis in his or her
shares, it will generally be treated as gain from the sale or exchange of that
stockholder's shares. The Company annually notifies stockholders of the
taxability of distributions paid during the preceding year.

         The following table sets forth the taxability of common stock
distributions paid in 1999 and 1998:

                                          1999               1998

             Ordinary income               78%                 92 %
             Capital gain                  22%                 --
             Return of capital             --                   8 %

     unamortized purchase price of certain third party real estate service
     contracts that were terminated in 1996 and the termination of an agreement
     to acquire the development business of The Evans Company in 1995.
(3)  The balance sheets have been restated to classify the assets, net of
     liabilities, of discontinued operations of the Company's executive suites
     affiliates into net assets of discontinued operations, a component of total
     assets.
(4)  The Company believes that funds from operations is helpful to investors as
     a measure of the performance of an equity REIT because, along with cash
     flow from operating activities, financing activities and investing
     activities, it provides investors with an indication of the ability of the
     Company to incur and service debt, to make capital expenditures and to fund
     other cash needs. In accordance with the final National Association of Real
     Estate Investment Trusts (NAREIT) White Paper on Funds From Operations as
     approved by the Board of Governors of NAREIT on March 3, 1995, funds from
     operations represents net income (loss) (computed in accordance with
     generally accepted accounting principles), excluding gains (or losses) from
     debt restructuring or sales of property, plus depreciation and amortization
     of assets uniquely significant to the real estate industry and after
     adjustments for unconsolidated partnerships and joint ventures. Adjustments
     for unconsolidated partnerships and joint ventures are calculated to
     reflect funds from operations on the same basis. The Company's funds from
     operations may not be comparable to funds from operations reported by other
     REITs that do not define the term in accordance with the current NAREIT
     definition or that interpret the current NAREIT definition differently than
     the Company. Funds from operations does not represent net income or cash
     flow generated from operating activities in accordance with generally
     accepted accounting principles and, as such, should not be considered an
     alternative to net income as an indication of the Company's performance or
     to cash flow as a measure of liquidity or the Company's ability to make
     distributions.


Item 7.  Management's Discussion and Analysis of Financial Condition and Results
         of Operations

         The following discussion is based primarily on the Consolidated
Financial Statements of CarrAmerica Realty Corporation and its subsidiaries (the
"Company") as of December 31, 1999 and 1998, and for the years ended December
31, 1999, 1998 and 1997. The comparability of the periods is significantly
impacted by acquisitions completed, development properties placed in service and
certain dispositions made during those years. The Company's owned properties
that were consolidated for financial statement purposes were 271 in 1999, 292 in
1998, 243 in 1997 and 159 in 1996. The comparability of the periods is also
impacted by development operations which grew significantly during the periods
presented.

         The Company's reportable operating segments are real estate property
operations and development operations. Other business activities and operating
segments that are not reportable are included in other operations. Executive
office suites are presented as discontinued operations in the Company's
financial statements.

                                       30
<PAGE>

         This information should be read in conjunction with the accompanying
consolidated financial statements and notes thereto. These consolidated
financial statements include all adjustments which are, in the opinion of
management, necessary to reflect a fair statement of the periods presented, and
all such adjustments are of a normal, recurring nature.


RESULTS OF OPERATIONS - 1999 TO 1998

Real Estate Property Operations

         Operating Revenue. Total real estate property operating revenue
increased $58.4 million, or 13.3%, to $498.9 million for 1999 as compared to
$440.5 million for 1998. This increase resulted from development properties
placed in service and same store rental growth which exceeded the loss of rental
revenue due to dispositions. Same store operating income grew by 6.4% or $13.0
million over the same period in 1998, primarily as a result of a 5.4% increase
in rental revenue. The average occupancy rate for same store properties
increased to 96.3% for 1999 from 96.1% for 1998.

         Segment Expense. Real estate property operating expenses increased
$17.5 million primarily as a result of development properties placed in service.
Same store operating expenses increased by $3.6 million, or 3.4%, over 1998
primarily due to higher real estate taxes and nonrecurring costs associated with
Y2K compliance work on building facilities and bad debt expenses.

         Interest Expense. Interest expense increased $3.7 million primarily due
to the refinancing of properties with increased leverage.

         Other Income (Expense), net. Other revenue generated by real estate
property operations increased $0.7 million primarily as a result of additional
interest income.

         Total Assets. The increase of $182.4 million, or 6.5%, from 1998 to
1999 is primarily as a result of the increase of development properties placed
in service.

Development Operations

         Development fee income increased $2.2 million, or 50.0%, to $6.6
million and development operating expenses increased $1.5 million to $4.6
million. These increases are the result of an increase in the number of
development fee projects.

         Total Assets. Total assets decreased $246.3 million, or 52.8% to $220.1
million in 1999 from $466.4 million in 1998 as a result of a $15.1 million
decrease in land held for development and a $231.2 million decrease in
construction in progress. This resulted primarily from an increase in
construction completions and properties placed in service and a decrease in
construction starts in 1999.

Other Operations

         Operating Revenue. Operating revenue decreased $1.4 million to $10.4
million in 1999 from $11.8 million in 1998.

         Segment Expense. The increase of $5.0 million to $34.3 million in 1999
from $29.3 million in 1998 is primarily a result of professional fees associated
with Project Excellence and Year 2000 Compliance work.

         Interest Expense. The $14.0 million increase in the Company's interest
expense is primarily related to an additional $150 million of senior unsecured
notes outstanding during the twelve months ended December 31, 1999 and
additional borrowings on the Company's unsecured line of credit.

                                       31
<PAGE>

Discontinued Operations

         Income (loss) from operations of discontinued executive suites
businesses decreased from income in 1998 of $6.5 million to a loss in 1999 of
$7.8 million. The decrease in earnings is primarily the result of start-up costs
incurred in 1999 for new executive suite centers and costs incurred to integrate
the various acquired operations.

         During 1998, the core executive suites operations were built primarily
through the acquisition of business centers. In 1999 there were fewer
acquisitions, however, more internal development of new centers. Losses incurred
during development for 1998 and 1999 were $5.0 million and $14.0 million,
respectively.


Consolidated Cash Flows

         Net cash provided by operating activities decreased $64.8 million, or
27.0%, to $175.0 million for 1999 as compared to $239.8 million for 1998. Net
income after non-cash adjustments provided $245.2 million of cash for the year
ended December 31, 1999, an increase of $34.0 million over the same period in
1998. This improvement was offset by uses of cash arising from changes in non
real estate assets and liabilities of $70.2 million in 1999 compared to cash
generated of $28.6 million in 1998. This $98.8 million change from 1998 to 1999
arises primarily from changes in the timing of payments for prepaids and other
assets from executive suites acquisitions of $31.5 million and changes in the
timing of payments for accounts payable and accrued expenses. In 1999, investing
activities provided $83.7 million compared to uses of $985.3 million for 1998,
primarily as a result of an increase in proceeds from sales of rental properties
as well as reduced outflow related to acquisitions and development of both
rental properties and executive suites assets. Net cash used by financing
activities totaled $238.4 million for the year ended December 31, 1999 compared
to net cash provided of $757.8 million for the comparable period in 1998. During
1998, proceeds from sales of common and preferred stock, issuance of senior
unsecured notes and an increase in borrowings on the Company's unsecured credit
facilities contributed 970 million compared to $57 million used by the Company
during 1999 to complete the repurchase of 5.0 million shares of common stock
under the Merrill Lynch forward equity sale transaction, net of proceeds from
refinancing existing mortgages.


RESULTS OF OPERATIONS - 1998 TO 1997

Real Estate Property Operations

         Operating Revenue. Total real estate property operating revenue
increased $115.0 million, or 35.3%, to $440.5 million for 1998 as compared to
$325.5 million for 1997. The Company experienced net growth in its rental
revenue as a result of its acquisitions, and development properties placed in
service, which together contributed approximately $105.1 million of additional
rental revenue in 1998. Rental revenue from properties that were fully
operational throughout both periods increased by approximately $9.9 million
primarily due to increased occupancy in these properties.

         Segment Expense. Real estate property operating expenses increased
$34.9 million primarily as a result of property acquisitions and development
properties placed in service. The Company also experienced an increase in
property operating expenses from properties that were fully operational in both
periods of approximately $2.9 million.

         Interest Expense. Interest expense increased $1.7 million due to the
acquisition of properties which were subject to existing mortgage debt.

         Other Income (Expense), net. Other revenue generated by real estate
property operations increased $4.2 million primarily as a result of additional
interest income and increased equity in earnings of unconsolidated partnerships.

         Total Assets. The increase of $504.7 million or 21.9% from 1997 to 1998
is primarily as a result of acquisitions of real estate and development
properties placed in service.

                                       32
<PAGE>

Development Operations

     Operating Revenues. Development fee income increased $1.3 million to $4.4
million in 1998 from $3.1 million in 1997 resulting from an increase in the
number of development fee projects.

     Segment Expenses. Segment expense increased $1.5 million to $3.1 million in
1998 from $1.6 million in 1997, primarily as a result of increases in general
and administrative expenses related to increased staffing.

     Total Assets. Total assets increased $173.9 million, or 59.5% to $466.4
million in 1998 from $292.5 million in 1997 as a result of an increase of $136.5
million and $37.5 million in construction in progress and land held for
development, respectively, primarily as a result of an increase in construction
starts from 1997 to 1998.

Other Operations

     Operating Revenue. The decrease of $1.1 million to $11.8 million in 1998
from $12.9 million in 1997 is a result of decreased management fee income.

     Segment Expense. The increase of $9.1 million to $29.3 million in 1998 from
$20.2 million in 1997 is as a result of the addition of new staff necessary to
implement the Company's business strategy.

     Interest Expense. The $18.2 million increase in the Company's interest
expense is primarily related to borrowings on the Company's line of credit
necessary to fund acquisitions and development commitments and the sale of
$350.0 million of senior unsecured notes.

     Other Income (Expense), net. Other expenses decreased $5.2 million to
$(0.3) million in 1998 from $(5.5) million in 1997 primarily as a result of
increased interest income.


Discontinued Operations

     Income from operations of executive suites businesses increased from $0.9
million in 1997 to $6.5 million in 1998, primarily the result of net operating
income earned from acquired executive suite businesses and the effect of having
a full year of operations in 1998 as compared to five months in 1997.


Consolidated Cash Flows

     Net cash provided by operating activities increased $106.7 million, or
80.2%, to $239.8 million for 1998 as compared to $133.1 million for 1997,
primarily as a result of the acquisitions made and development placed in service
by the Company. Net cash used by investing activities decreased $13.4 million,
to $985.3 million for 1998 as compared to $998.7 million for 1997, primarily as
a result of capital deployed by the Company for acquisitions of office
properties, executive office suites businesses, land held for future
development, investments in construction in progress and proceeds from the sale
of rental property. Net cash provided by financing activities decreased $104.1
million, to $757.8 million for 1998 as compared to $861.9 million for 1997,
primarily as a result of a reduction in the amount of proceeds from the sale of
common and preferred stock and an increase in the amount of dividends paid to
the common and preferred stockholders. These items were offset by an increase in
borrowings on the Company's unsecured credit facility and the issuance of
unsecured notes.


LIQUIDITY AND CAPITAL RESOURCES

     The Company seeks to create and maintain a capital structure that will
enable it to diversify its capital sources and thereby allow the Company to
obtain additional capital from a number of different sources, including
additional equity offerings of common and/or preferred stock, public and private
debt financings, and, where appropriate, asset dispositions. Management believes
that the Company will have access to the capital resources necessary to expand
and develop its business, to fund its operating and administrative expenses, to
continue debt service obligations, to pay dividends in accordance with REIT
requirements, to acquire additional properties and land, and to pay for
construction in progress in both the short and long term.

                                       33
<PAGE>

     The Company has three investment grade ratings. Duff & Phelps Credit Rating
Co. (DCR) and Standard & Poors (S&P) each had assigned their BBB rating to
prospective senior unsecured debt offerings of the Company and their BBB-rating
to prospective cumulative preferred stock offerings of the Company as of
December 31, 1999. Moody's Investor Service (Moody's) has assigned its Baa3
rating to prospective senior unsecured debt offerings of the Company and its Ba2
rating to prospective cumulative preferred stock offerings of the Company as of
December 31, 1999.

     The Company's total indebtedness at December 31, 1999 was $1.6 billion, of
which $343 million, or 21.4%, bore a LIBOR-based floating interest rate. The
weighted average interest rate under the unsecured credit facility for 1999 was
6.7%. Currently, the unsecured credit facility bears interest at 90 basis points
over 30 day LIBOR. The Company's mortgage payable fixed rate indebtedness bore
an effective weighted average interest rate of 8.04% at December 31, 1999 and
has a weighted average term to maturity of 7.3 years. Based upon the Company's
total market capitalization at December 31, 1999 of $3.566 billion (the common
stock price was $21.13 per share; the total shares of common stock, convertible
preferred stock and Units outstanding was 73,986,131 and the aggregate
liquidation value of the cumulative redeemable preferred stock was $400.0
million), the Company's debt represented 45.0% of its total market
capitalization. The Company has a $450.0 million unsecured credit facility, of
which $343.0 million had been advanced, letters of credit totaling $3.7 million
were issued, and $103.3 million was available for draw. HQ Global has a $200.0
million unsecured credit facility, which is guaranteed by the Company. As of
December 31, 1999, $140.5 million had been advanced, letters of credit totaling
$10.8 million were issued, and $48.7 million was available for draw under the HQ
Global unsecured credit facility. It is contemplated that the HQ Global facility
will be repaid and terminated in connection with the proposed HQ Global/VANTAS
transaction.

     Rental revenue and real estate service revenue have been the principal
sources of capital to fund the operating expenses, debt service and capital
expenditures of the Company and its affiliates, excluding non-recurring capital
expenditures. The Company believes that these sources of revenue will continue
to provide the necessary funds for its operating expenses and debt service. The
Company and its affiliates also require capital to invest in its existing
portfolio of operating assets for major capital projects such as large-scale
renovations, routine capital expenditures and deferred maintenance on certain
properties recently acquired and tenant related capital expenditures, such as
tenant improvements and allowances and leasing commissions.

     Additionally, the Company and its affiliates (including CarrAmerica
Development) will require a substantial amount of capital for development
projects currently underway and planned for the future. As of December 31, 1999,
the Company (including CarrAmerica Development) had approximately 1.3 million
square feet of office space in 22 development projects underway which are
expected to require a total investment by the Company of approximately $244.9
million. As of December 31, 1999, $149.0 million, or 60.8% of the total expected
investment, had been expended.

     Historically, management has primarily met the Company's capital
requirements by accessing the public equity and debt markets. However, because
of unfavorable conditions currently existing in the REIT public equity and debt
markets, the Company does not believe that these markets are currently providing
the Company with the most attractive sources of capital. If conditions in the
public equity or debt markets improve, the Company will evaluate the cost of
capital raised in such markets to determine if it is the most attractive capital
available to the Company at the time. However, there can be no assurance that
conditions will improve in the near term. During 1999 and 1998 the Company
funded its new development through proceeds from dispositions of properties. In
addition, the Company announced the agreement with FrontLine Capital which is
expected to provide the Company with estimated cash of $170.0 million.

     If (i) the debt and equity capital markets do not improve, (ii) the Company
is unable to raise the expected net proceeds from dispositions of properties,
and (iii) the Company is unable to obtain capital from other sources, the
Company believes that it would continue to have sufficient funds to continue to
pay its operating and debt service expenses, its regular quarterly dividends and
to meet the necessary capital requirements with respect to its existing
portfolio of operating assets. However, the Company's ability to continue to
fund all of its current development projects could be adversely affected. If the
Company determined that it was in the best interests of the Company to continue
to fund all of its current development projects, the Company may have to access
either the public equity or debt markets, which, at that time, may not be the
most attractive source of capital.

     Net cash provided by operating activities was $175.0 million for the year
ended December 31, 1999, compared to $239.8 million for the year ended December
31, 1998. The decrease in net cash provided by operating activities was
primarily a result of changes in the timing of payments for prepaid and other
assets and

                                       34
<PAGE>

accounts payable and accrued expenses. The Company's investing activities
provided approximately $83.7 million in 1999 and used approximately $985.3
million for the year ended December 31, 1998. The Company's investing activities
include investment in existing real estate and executive office suites assets
and acquisitions of office buildings (directly and through CarrAmerica
Development), executive office suites businesses (through HQ Global, Omni UK and
LUX), and land held for future development and additions to construction in
progress (directly and through CarrAmerica Development) and executive office
suites development (through HQ Global, Omni UK and LUX). These investments
declined from $1.087 billion in 1998 to $441.8 million in 1999. In addition, in
1999, the Company generated $487.9 million from sales of rental property
compared to $194.1 million in 1998. Net of distributions to the Company's
stockholders and minority interests, the Company's financing activities used net
cash of $65.7 million in 1999 and provided $930.9 million for the year ended
December 31, 1998. During 1998, the Company raised $969.5 million from stock
sales, issuance of notes and borrowings on the unsecured lines of credit. In
1999, the Company used $56.8 million of funds to repurchase 5.0 million shares
of common stock, net of proceeds from the refinance of existing mortgages.

     The Company plans to refinance the $150 million senior unsecured note due
October 1, 2000.

     The Company's dividends are paid quarterly. Amounts accumulated for
distribution are primarily invested by the Company in short-term investments
that are collateralized by securities of the United States Government or certain
of its agencies.


Year 2000 Compliance

     The Year 2000 issue is the risk that computer programs using two-digit date
fields will fail to properly recognize the Year 2000, with the result being
business interruptions due to computer system failures by the Company's software
or hardware or by government entities, service providers and vendors.

     With the assistance of a consulting firm and the Company's Steering
Committee, the Company completed its assessment of the exposure to Year 2000
issue and successfully remediated areas of exposure. As of December 31, 1999,
the Company had incurred approximately $2.75 million in costs for its Year 2000
program. The Company currently estimates that it will incur additional costs,
which are not expected to exceed $0.1 million, to complete its Year 2000
compliance work. To the date of this report, the Company has not encountered any
significant business interruptions or material adverse financial consequences
related to the Year 2000 issue. However, there can be no assurances that the
Company will not encounter material business interruptions or adverse financial
consequences subsequent to the date of this report.


Funds From Operations

     The Company believes that funds from operations is helpful to investors as
a measure of the performance of an equity REIT because, along with cash flow
from operating activities, financing activities and investing activities, it
provides investors with an indication of the ability of the Company to incur and
service debt, to make capital expenditures and to fund other cash needs. In
accordance with the final National Association of Real Estate Investment Trusts
(NAREIT) White Paper on Funds From Operations as approved by the Board of
Governors of NAREIT on March 3, 1995, funds from operations represents net
income (loss) (computed in accordance with generally accepted accounting
principles), excluding gains (or losses) from debt restructuring or sales of
property, plus depreciation and amortization of assets uniquely significant to
the real estate industry and after adjustments for unconsolidated partnerships
and joint ventures. Adjustments for unconsolidated partnerships and joint
ventures are calculated to reflect funds from operations on the same basis. The
Company's funds from operations may not be comparable to funds from operations
reported by other REITs that do not define the term in accordance with the
current NAREIT definition or that interpret the current NAREIT definition
differently than the Company. Funds from operations does not represent net
income or cash flow generated from operating activities in accordance with
generally accepted accounting principles and, as such, should not be considered
an alternative to net income as an indication of the Company's performance or to
cash flow as a measure of liquidity or the Company's ability to make
distributions.

Item 7A.   Quantitative and Qualitative Disclosures About Market Risk

     Increases in interest rates, or the loss of the benefits from any hedging
agreements of the Company, would increase our interest expense, which would
adversely affect cash flow. As of December 31, 1999, the Company had $343.0
million outstanding under its line of credit that bears interest at a floating
rate and $635.4 of additional fixed rate mortgage debt. HQ Global also had
$140.5 million outstanding under its unsecured credit facility as of December
31, 1999 which was guaranteed by the Company. The unsecured credit facilities
mature in August 2001 and the mortgage loans mature at various times through
2009. The Company also has issued $625 million senior unsecured notes, which
mature between 2000 and 2008.

     The Company is currently a party to an interest rate hedge agreement in
order to hedge against the impact that interest rate fluctuations would have on
the floating rate debt under its line of credit. Although the hedging agreements
enable us to convert floating rate liabilities to fixed rate liabilities, they
expose us to the risk that the counterparties to such hedge agreements may not
perform, negating the benefit of the hedging arrangements. In addition, if
interest rates decline after we enter into a hedging agreement, our interest
expense would be higher than the underlying floating rate and could result in us
making payments to unwind such agreements. The Company has entered into an
interest rate swap agreement effective October 12, 1999 which converts $100
million of its variable rate debt to fixed rate debt to reduce the Company's
market risk from changes in interest rates. The interest rate swap agreement
expires April 12, 2000.

     The Company's future earnings, cash flow and fair values relevant to
financial instruments are dependent upon prevailing market rates. Market risk is
the risk of loss from adverse changes in market prices and interest rates. The
Company manages its risk by matching projected cash inflows from operating
activities, financing activities and investing activities with projected cash
outflows to fund debt payments, acquisitions, capital expenditures,
distributions, and other cash requirements. The Company also uses certain
derivative financial instruments at times to limit market risk. Interest rate
protection agreements are used to convert floating rate debt to a fixed rate
basis or to hedge anticipated financing transactions. Derivatives are used for
hedging purposes rather than speculation. The Company does not enter into
financial instruments for trading purposes.

                                       36

     If the market rates of interest on the Company's variable rate debt change
by 10% (or approximately 56 basis points) the Company's interest expense would
change by approximately $2.7 million, assuming the amount outstanding under the
variable rate credit facilities remains at $483.5 million, the balance at
December 31, 1999. Furthermore book value of these variable interest credit
facilities approximates market value at December 31, 1999.

     A change in interest rates generally does not impact future earnings and
cash flows for fixed rate debt instruments, but as fixed rate debt matures and
if additional debt is acquired to fund the repayments under maturing facilities,
future earnings and cash flows may be impacted by changes in interest rates.
This impact would be realized in the periods subsequent to debt maturities. The
following is a summary of the fixed rate mortgages and senior unsecured debt
maturities (in thousands):

                   2000                            $   197,567
                   2001                                100,223
                   2002                                 44,627
                   2003                                 55,224
                   2004                                171,400
                   2005 & thereafter                   691,330
                                                   -----------
                                                   $ 1,260,371
                                                   ===========

     Assuming the repayments of fixed rate borrowings are made in accordance
with the terms and conditions of the respective credit arrangements, a 10
percent change in the market interest rate for the respective fixed rate debt
instruments would change the fair value of the Company's fixed rate debt by
approximately $25 million. The estimated fair market value of the fixed rate
debt instruments and the senior unsecured notes at December 31, 1999 was $659.0
million and $584.8 million, respectively.

     Because we have made loans to foreign affiliates, Omni UK and LUX, we are
exposed to risks that there will be a significant change in the rate of exchange
between the United States dollar and various foreign currencies, as well as the
possibility of the imposition or modification of exchange controls by
governments or monetary authorities. These risks generally depend on factors
beyond our control, such as economic, financial and political events and the
supply and demand for various currencies. We may invest in other entities with
operations in foreign countries, and if we do, the same risks will apply to the
currencies utilized in those countries. The Company's current exposure to
foreign currency fluctuations is not significant.

                   Notes to Consolidated Financial Statements
- --------------------------------------------------------------------------------

(1)  Description of Business and Summary of Significant Accounting Policies

(a)  Business

     CarrAmerica Realty Corporation (the "Company") is a self-administered and
self-managed equity real estate investment trust ("REIT"), organized under the
laws of Maryland, which owns, develops, acquires and operates office properties.
The Company's office properties primarily are located in 14 suburban markets
across the United States.

(b)  Basis of Presentation

     The accounts of the Company and its majority-owned/controlled subsidiaries
and affiliates are consolidated in the accompanying financial statements. The
Company uses the equity method of accounting for its investments in and earnings
and losses of unconsolidated partnerships not majority-owned/controlled by the
Company. Management of the Company has made a number of estimates and
assumptions relating to the reporting of assets and liabilities, revenues and
expenses, and the disclosure of contingent assets and liabilities to prepare
these financial statements in conformity with generally accepted accounting
principles. Actual results could differ from those estimates.

     The Company conducts an executive suites business through its affiliates HQ
Global Workplaces, Inc. ("HQ Global"), OmniOffices (UK) Limited ("Omni UK"), and
OmniOffices (Lux) 1929 Holding Company S.A. ("LUX"). On January 20, 2000, the
Company, HQ Global, VANTAS Incorporated ("VANTAS") and Reckson Service
Industries, Inc. d/b/a FrontLine Capital Group ("FrontLine Capital Group")
entered into several agreements pursuant to which a series of transactions will
occur, including (i) the merger of VANTAS with and into HQ Global, (ii) the
acquisition by FrontLine Capital Group of certain shares of common stock of HQ
Global from the Company and other stockholders of HQ Global, and (iii) the
acquisition by HQ Global from the Company of the Company's debt and equity
interests in Omni UK and LUX. Following the completion of these transactions,
FrontLine Capital Group will own a substantial majority of the outstanding stock
of HQ Global, with the Company retaining a minority interest in HQ Global. The
net assets and results of the executive suites business are reported as a
discontinued operation and certain reclassifications of prior year information
have been made to conform to the current year presentation.

(c)  Rental Property

     Rental property is recorded at cost less accumulated depreciation (which is
less than the fair value of the rental property). Depreciation is computed on
the straight-line basis over the estimated useful lives of the assets, as
follows:

<TABLE>
       <S>                                                          <C>
       Base Building..............................................  30 to 50 years
       Building components........................................  7 to 20 years
       Tenant improvements........................................  Terms of the leases or useful
                                                                    lives, whichever is shorter
       Leasehold improvements, furniture, fixtures and equipment..  5 to 15 years
</TABLE>

     Expenditures for maintenance and repairs are charged to operations as
incurred. Significant renovations are capitalized.

     The Company reviews its long-lived assets for impairment whenever events or
changes in circumstances indicate that the carrying amount of an asset may not
be recoverable. Recoverability of assets to be held and used is measured by a
comparison of the carrying amount of an asset to future net cash flows expected
to be generated by the asset. If such assets are considered to be impaired, the
impairment to be recognized is measured by the amount by which the carrying
amount of the assets exceed the fair value of the assets.

     The Company reviews its rental property to determine the point at which the
asset is under contract for sale, with contingencies waived and nonrefundable
earnest money posted. If an asset is subject to these conditions, the asset is
reclassified to "Assets Available for Sale", and depreciation is discontinued.

                   Notes to Consolidated Financial Statements
- --------------------------------------------------------------------------------

(d)  Development Property

     Land held for development and construction in progress is carried at cost.
Specifically identifiable direct and indirect, development, construction and
external acquisition costs are capitalized including, where applicable, salaries
and related costs, real estate taxes, interest and certain pre-construction
costs essential to the development of a property.

(e)  Tenant Leasing Costs

     Fees and costs incurred in the successful negotiation of leases have been
deferred and are being amortized on a straight-line basis over the terms of the
respective leases.

(f)  Deferred Financing Costs

     Deferred financing costs include fees and costs incurred to obtain
financing and are being amortized over the terms of the respective loans on a
basis which approximates the interest method.

(g)  Goodwill, Real Estate Service Contracts and Other Intangibles

     Goodwill, which represents the excess of purchase price over the fair value
of net assets acquired in the acquisition of the now discontinued executive
suites businesses, is amortized on the straight-line basis over 30 years.

     Real estate service contracts and other intangible assets represent the
fair value of assets acquired and are amortized on the straight-line basis over
their expected lives.

     The Company assesses the recoverability of these intangible assets by
determining whether the balance can be recovered over its remaining life through
undiscounted future operating cash flows of the related assets or operations
acquired. The amount of impairment loss, if any, is measured as the amount by
which the carrying amount of the assets exceeds the fair value of the assets.
The assessment of the recoverability of these intangible assets will be impacted
if estimated future operating cash flows are not achieved.

(h)  Fair Value of Financial Instruments

     The carrying amount of the following financial instruments approximates
fair value because of their short-term maturity: cash and cash equivalents;
accounts and notes receivable; accounts payable and accrued expenses.

(i)  Revenue Recognition

     The Company reports base rental revenue for financial statement purposes
straight-line over the terms of the respective leases. Accrued straight-line
rents represent the amount that straight-line rental revenue exceeds rents
collected in accordance with the lease agreements. Management, considering
current information and events regarding the tenants' ability to fulfill their
lease obligations, considers accrued straight-line rents to be impaired if it is
probable that the Company will be unable to collect all rents due according to
the contractual lease terms. If accrued straight-line rents associated with a
tenant are considered to be impaired, the amount of the impairment is measured
based on the present value of expected future cash flows. Impairment losses, if
any, are recorded through a loss on the write-off of assets. Cash receipts on
impaired accrued straight-line rents are applied to reduce the remaining
outstanding balance and as rental revenue, thereafter.

     Real estate service revenue for certain properties it manages, leases and
develops for third parties is recognized when services are performed.

(j)  Income and Other Taxes

     The Company qualifies as a REIT under Sections 856 through 860 of the
Internal Revenue Code of 1986, as amended. A REIT will generally not be subject
to federal income taxation on that portion of its income that qualifies as REIT
taxable income to the extent that it distributes at least 95 percent of its
taxable income to its shareholders and complies with certain other requirements.
Accordingly, no provision has been made for

federal income taxes for the Company and certain of its subsidiaries in the
accompanying consolidated financial statements.

     Certain subsidiaries, organized as partnerships, of the Company are subject
to District of Columbia franchise tax which is included in income taxes in the
accompanying consolidated financial statements.

     CarrAmerica Development, Inc. ("CarrAmerica Development"), the Company's
development affiliate, Carr Real Estate Services, Inc. ("Carr Services, Inc."),
the Company's real estate service affiliate, HQ Global, Omni UK and LUX, file
separate tax returns and are subject to federal, state and local income taxes as
well as certain foreign taxes. The Company uses the asset and liability method
of accounting for income taxes for these affiliates as measured by enacted tax
rules and regulations

(k)  Hedging Transactions

     From time to time, the Company enters into interest rate lock and collar
agreements that are designed to hedge against the impact of interest rate
fluctuations on certain of the Company's existing and probable future long-term
debt instruments. Because these agreements qualify for hedge accounting
treatment, any gains or losses are recognized as adjustments to interest expense
over the lives of the underlying debt instruments. For hedge agreements that are
terminated early or that are associated with anticipated future debt
instruments, gains or losses are deferred until those debt instruments are
entered into. If the Company determines it is no longer probable that the
Company will enter into an anticipated debt instrument, or the investment no
longer effectively hedges the existing or probable future long-term debt
instruments, any related deferred gains or losses are recognized in the current
period.

(n)  Accumulated Other Comprehensive Income

     The financial statements of Omni UK and LUX, foreign affiliates, have been
prepared in the respective local currency and translated into U.S. dollars based
on the current exchange rate at the end of the period for assets and liabilities
and at an average exchange rate for the period on the statement of operations.
Translation adjustments have no effect on net income and are in other net assets
of discontinued operations. Comprehensive income of the Company represents net

$141.7 million in 1999 and $127.0 million in 1998.

(o)  Segment Operations

     The Company's reportable segments are real estate property operations and
development operations. Other business activities and operating segments that

Company, at either (i) the higher of the prime rate or the Federal Funds Rate
for such day or (ii) an interest rate equal to 90 basis points above the 30 day
London Interbank Offered Rate (LIBOR). The Company has predominately selected
interest rates equal to 90 basis points above the 30 day LIBOR rate for initial
draws and upon the expiration of current LIBOR contracts. The credit facility
matures in August 2001. At December 31, 1999, the Company had $103.3 million
available for draw under the credit facility.

     The Company's unsecured credit facility contains a number of financial and
other covenants with which the Company must comply including, but not limited
to, covenants relating to ratios of annual EBITDA (earnings before interest,
taxes, depreciation and amortization) to interest expense, annual EBITDA to debt
service, and total debt to tangible fair market value of the Company's assets,
and restrictions on the ability of the Company to make dividend distributions in
excess of 90% of funds from operations. Availability under the unsecured credit
facility is also limited to a specified percentage of the Company's unsecured
properties.

issued in 1998. The notes due in 2004 and 2007 were issued in 1997. The
Company's senior unsecured notes contain various covenants with which the
Company must comply: limits on both the aggregate amount of indebtedness and
secured indebtedness the Company may have outstanding on a consolidated basis;
and, limits on the Company's required debt service payments. The senior
unsecured notes are unconditionally guaranteed by CarrAmerica Realty, L.P.

value of these mortgages at December 31, 1999 and 1998 was approximately $659.0
million and $615.5 million, respectively. The fair market value of the senior
unsecured notes payable at December 31, 1999 and 1998 was $584.8 million and

     The executive suite businesses lease certain commercial office space for
its operations under noncancellable operating leases with initial terms ranging
from 10 to 15 years. Future minimum lease payments required under these
operating leases as of December 31, 1999 were (in thousands) $83,018 for 2000;

businesses. The merger is scheduled to close on or before April 30, 2000. The
proposed transaction is subject to satisfaction of a number of conditions. There

(4)  Minority Interest

     In conjunction with the formation of the Company and its majority-owned
subsidiary, Carr Realty, L.P., persons contributing interests in properties to
Carr Realty, L.P. had the right to elect to receive either common stock of the
Company or Units in Carr Realty, L.P. In addition, the Company has acquired
certain assets since its formation by issuing distribution paying Units and non-
distribution paying Units of Carr Realty, L.P. and CarrAmerica Realty, L.P. The
non-distribution paying Units are not entitled to any distributions until they
automatically convert into distribution paying Units at various dates in the
future. During the year ended December 31, 1999, 107,919 non-distribution paying
units of CarrAmerica Realty, L.P. were converted to 108,673 distribution paying
units. Each distribution paying Unit, subject to certain restrictions, may be
redeemed for either one share of common stock or, at the option of the Company,
cash equal to the fair market value of a share of common stock at the time of
the redemption. When a Unitholder redeems a distribution paying Unit for a share
of common stock or cash, minority interest is reduced and the Company's
investment in Carr Realty, L.P. or CarrAmerica Realty, L.P., as the case may be,
is increased. During the years ended December 31, 1999 and 1998, 38,430 and
51,613 distribution paying Units, respectively, of Carr Realty, L.P. were
redeemed for common stock of the Company.

(8)  Stock/Unit Option Plans

     As of December 31, 1999, the Company had three option plans: two plans
for the purpose of attracting and retaining executive officers and other key
employees (1997 Employee Stock Option and Incentive Plan and the 1993 Carr
Realty Option Plan); and the other plan for the purpose of attracting and
retaining directors who are not employees of the Company (1995 Non-Employee
Director Stock Option Plan).

     The 1997 Employee Stock Option and Incentive Plan ("Stock Option Plan")
allows for the grant of options to purchase the Company's common stock at an
exercise price which is equal to the fair market value of the common stock at
the date of grant. The Stock Option Plan was approved by the Company's
stockholders at its Annual Meeting of Stockholders on May 8, 1997. At December
31, 1999, the Company had options and units to purchase 10,000,000 shares of
common stock and units reserved for issuance under the Stock Option Plan, of
which 5,225,621 were outstanding. All of the outstanding options have a 10-year
term from the date of grant. The majority of the options vest over a five-year
period, 20% per year, with the exception of 1,492,500 options which vest over a
four-year period, 25% per year, and 450,000 options which vest at the end of
five years.

     The 1993 Carr Realty Option Plan allows for the grant of options to
purchase Units of Carr Realty, L.P. (Unit options) that are exercisable at the
fair market value of the Units at the date of grant, which is deemed to be
equivalent to the fair market value of the Company's common stock at such date.
Units (following exercise of Unit options) are redeemable for cash or common
stock of the Company, at the option of the Company. At December 31, 1999, the
Company had options to purchase 1,266,900 Units authorized for grant under the
1993 Carr Realty Option Plan, of which 820,622 were outstanding. All of the
outstanding options have a 10-year term from the date of grant and vest over a
five-year period, 20% per year

     The 1995 Non-Employee Director Stock Option Plan provides for the grant of
options to purchase the Company's common stock at an exercise price which is
equal to the fair market value of the common stock on the date of grant. Under
this plan, each newly elected non-employee director was granted options to
purchase 3,000 shares of the Company's common stock upon commencement of
service. In connection with each annual election of directors, each continuing
non-employee director will receive options to purchase 7,500 shares of the
Company's common stock. The stock options have a 10-year term from the date of
grant and vest over a three-year period, 33 1/3% per year. At December 31, 1999,
the Company had 270,000 shares of common stock authorized for grant under the
1995 Non-Employee Director Stock Option Plan, of which 243,392 were outstanding.

     The per share weighted-average fair values of Unit options and stock
options granted during 1999, 1998 and 1997 was $2.25, $2.38 and $2.84,
respectively, on the date of grant using the Black Scholes option-pricing model
with the following weighted-average assumptions: 1999 - expected dividend yield
of 7.54%, risk free interest rate of 5.16%, stock volatility of 22.78%, and
expected option life of 3.95 years; 1998 - expected dividend yield of 7.38%,
risk free interest rate of 5.05%, stock volatility of 21.82%, and expected
option life of 5.00 years; 1997 - expected dividend yield of 7.36%, risk free
interest rate of 6.26%, stock volatility of 19.42%, and expected option life of
5.46 years.

     The Company applies APB Opinion No. 25 in accounting for its Unit options
and stock options. Pro forma information regarding net income and earnings per
share is required by SFAS No. 123 and has been determined as if the Company had
accounted for its unit and stock options under the fair value method. For 1999
and 1998 the Company's pro forma net income and basic EPS was $140,507 and
$1.55, and $125,026 and $1.30, respectively.

(9)      Transactions With Affiliates

         Accounts receivable includes management and leasing fees, development
and architectural fees and payroll reimbursements receivable from affiliates of
$6.1 million at December 31, 1999 and $3.5 million at December 31, 1998. This
amount includes a leasing commission receivable of $2.1 million at December 31,
1999 and $2.3 million at December 31, 1998, which receivable is collectible in
quarterly installments of approximately $47,000 through September 2011. The fair
market value of this receivable is $1.4 million at December 31, 1999 and $1.5
million at December 31, 1998. The leasing commission is due from an
unconsolidated investee partnership.

         The Company earned management, leasing, development and architectural
fees from affiliated partnerships of $7.9 million in 1999, $6.1 million in 1998,
and $7.4 million in 1997.

         A wholly owned subsidiary of Clark Enterprises, Inc., a Unitholder, has
provided construction management services to the Company. In connection with
these services, the Company paid $3.1 million in 1999, $19.6 million in 1998,
and $1.5 million in 1997. Additionally, a wholly owned subsidiary of Clark
Enterprises, Inc. received a total of $19.6 million during the years of 1997,
1996 and 1995 under a construction contract for the Booz-Allen & Hamilton
Building (in which the Company is a 50% joint venturer).

         The Company formerly leased office space from a partnership affiliated
with The Oliver Carr Company. Rent expense amounted to $0.6 million in 1998 and
$1.2 million in 1997 under the lease.

         During 1999 and 1998, payments of $0.2 million and $0.3 million,
respectively were made to Security Capital Investment Research Incorporated, an
affiliate of SC-USREALTY, for research rendered in connection with the
acquisition of operating properties, executive office suites businesses and
development properties.

(10)     Gains/Losses From Dispositions of Assets

         The Company has disposed of assets that are inconsistent with its
long-term strategic or return objectives or where market conditions for sale are
favorable. The proceeds of the sales were redeployed into other office
properties (utilizing tax-deferred exchanges in some cases). During 1999, the
Company disposed of 63 operating properties and two parcels of land that were
being held for development. The Company recognized a gain totaling $54.8 million
on these dispositions which is net of District of Columbia Franchise tax of $0.6
million. During 1998, the Company disposed of 13 operating properties and one
parcel of land. The Company recognized a gain totaling $38.2 million on these
dispositions. During 1997, the Company disposed of seven operating properties.
The Company recognized a gain totaling $5.4 million on these dispositions.

  (11)   Commitments and Contingencies

         At December 31, 1999, the Company is contingently liable on letters of
credit amounting to approximately $3.7 million for various completion escrows
and on performance bonds amounting to approximately $13.1 million to ensure
completion of required public improvements on its construction projects.

         The Company has entered into an interest rate cap agreement on June 22,
1998 in the notional amount of $200 million at a rate of 9.5%. In addition, on
October 25, 1999, the Company entered into an interest rate swap agreement in
the notional amount of $100 million at a fixed rate of 5.83% against the 30-day
LIBOR rate on the unsecured line of credit. The agreements were entered into in
order to hedge against the impact that interest rate fluctuations would have on
the interest rate attainable on the Company's line of credit. As of December 31,
1999, unrealized gain/loss on the agreements was zero.

         The Company entered into forward treasury agreements in order to hedge
against the impact that interest rate fluctuations would have on debt
instruments the Company planned to issue in the future. At December 31, 1998,
the Company determined that these positions no longer represented effective
hedges and, accordingly, the amount due to the counterparty under the forward
Treasury Lock Agreements of $13.7 million was recognized in the Company's
financial statements as a loss. These contracts were settled on February 12,
1999, for $9.2 million in cash, resulting in a gain of $4.5 million.

         The Company has a 401(k) plan for employees that will match 50% of
employee contributions up to the first 4% of an employee's pay and will make a
base contribution of 3% of pay for participants who remain employed on December
31 (the end of the plan year). Company contributions to the plan are subject to
a five-year graduated vesting schedule. Company contributions to the plan
amounted to $ million in 1999, $1.1 million in 1998 and $0.6 million in 1997.

         The Company currently is involved in litigation with two stockholders
of HQ Global Workplaces, Inc. involving the conversion in September 1998 of
approximately $111 million of debt previously loaned by the Company to HQ Global
into stock of HQ Global. The Company and HQ Global initiated this litigation by
filing a complaint seeking a declaratory judgment that the terms of the debt
conversion were fair, after these two stockholders threatened to challenge the
terms of the conversion, claiming that the conversion price utilized, and the
methods by which the conversion price was agreed upon between the Company and HQ
Global, were not fair to HQ Global or these stockholders. The two stockholders
filed counterclaims against the Company, HQ Global and the board of directors of
HQ Global seeking a judgment declaring the conversion void or voidable, or in
the alternative compensatory and punitive damages.


         Although the Company believes that the two stockholders' claims are
without merit and that it and HQ Global will ultimately prevail in their actions
against the two stockholders, there can be no assurance that the court will not
find the conversion price to have been unfair and declare the conversion void,
which would have the effect of diluting the Company's equity interest in HQ
Global or award the two stockholders compensatory and punitive damages. However,
even if the two stockholders were successful in their claims, the Company does
not believe that such a result would have a material adverse effect on the
financial condition or results of operations of the Company or HQ Global.

         In the course of the Company's normal business activities, various
lawsuits, claims and proceedings have been or may be instituted or asserted
against the Company. Based on currently available facts, management believes
that the disposition of matters that are pending or asserted will not have a
material adverse effect on the consolidated financial position, results of
operations or liquidity of the Company.

The Board of Directors and Stockholders
CarrAmerica Realty Corporation:

         We have audited the accompanying consolidated balance sheets of
CarrAmerica Realty Corporation and subsidiaries as of December 31, 1999 and 1998
and the related consolidated statements of operations, stockholders' equity, and
cash flows for each of the years in the three-year period ended December 31,
1999. These consolidated financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
consolidated 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 financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

         In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of CarrAmerica
Realty Corporation and subsidiaries as of December 31, 1999 and 1998, and the
results of their operations and their cash flows for each of the years in the
three-year period ended December 31, 1999, in conformity with generally accepted
accounting principles.

     1.  The Company deems it appropriate to execute this certificate to
evidence adoption of an amendment to its 1997 Stock Option and Incentive Plan
(the "Plan") that increased the number of shares of common stock available for
issuance pursuant to grants under the Plan from 7,200,000 to 10,000,000 (the
"Amendment").

     2.  The Board of Directors of the Company adopted the Amendment, determined
that the Amendment should be submitted to the Company's stockholders for
approval, and directed that the Amendment be submitted to the stockholders for
approval at the next annual meeting of stockholders.

     3.  The Amendment was submitted to the stockholders for approval at the
annual meeting of stockholders of the Company held on May 6, 1999, and was
approved by the stockholders.

     4.  Section 4 of the Plan therefore has been amended, effective as of May
6, 1999, and now reads as follows:

     "4. STOCK SUBJECT TO THE PLAN

     Subject to adjustment as provided in Section 16 hereof, the number of
shares of Stock available for issuance under the Plan shall be 10,000,000.
Stock issued or to be issued under the Plan shall be authorized but unissued
shares.  If any shares covered by a Grant are not purchased or are forfeited, or
if a Grant otherwise terminates without delivery of any Stock subject thereto,
then the number of shares of Stock counted against the aggregate number of
shares available under the Plan with respect to such Grant shall, to the extent
of any such forfeiture or termination, again be available for making Grants
under the Plan."

     IN WITNESS WHEREOF, the Company has caused this certificate to be signed by
the undersigned, a duly authorized officer of the Company, as of May 6, 1999.

          THIS CONSOLIDATED, AMENDED AND RESTATED PROMISSORY NOTE (this "Note")

               dated April 26, 1996 between Borrower and Lender.

          2.   Promissory Note dated September 16, 1993 in the original
               principal amount of $40,000,000.00 made by Carr Realty Square 106
               Partnership ("Square 106") and payable to the order of Lender, as

<PAGE>

               to Promissory Note dated April 26, 1996 between Borrower and
               Lender.

The Existing Notes and the respective principal amount of indebtedness evidenced
thereby and additional indebtedness of Borrower to Lender are hereby combined
and consolidated to constitute one indebtedness in the principal amount of ONE
HUNDRED EIGHTY-THREE MILLION SEVEN HUNDRED THOUSAND DOLLARS ($183,700,000.00).
The manner and timing of payment and the other terms, covenants, agreements and
provisions of the Existing Notes are hereby modified, amended and restated in
their entirety so that henceforth the terms, provisions, covenants and
agreements thereof shall be as set forth herein, and in the event of any
conflict in the terms, provisions, covenants or agreements between the Existing
Notes and this Note, this Note shall prevail.  The Existing Notes are attached
hereto and shall be negotiated only with this Note.

          For value received, Borrower promises to pay to the order of Lender,
at 720 E. Wisconsin Avenue, Milwaukee, WI  53202 or at such other place as
Lender shall designate in writing, in coin or currency which, at the time or
times of payment, is legal tender for public and private debts in the United
States, the principal sum of ONE HUNDRED EIGHTY-THREE MILLION SEVEN HUNDRED
THOUSAND DOLLARS or so much thereof as shall have been advanced from time to
time plus interest on the outstanding principal balance at the rate and payable
as follows:

               Interest shall accrue from the date of advance until maturity at
          the rate of eight and twelve hundredths percent (8.12%) per annum (the
          "Interest Rate").

               Accrued interest only on the amount advanced shall be paid in
          arrears on the first day of the month following the date hereof and on
          the first day of each month thereafter until and including the
          Amortization Period Commencement Date.  On the first day of the month
          following the Amortization Period Commencement Date, and on the first
          day of each month thereafter until maturity, installments of principal
          and interest shall be paid in an amount equal to the unpaid principal
          balance of this Note on the Amortization Period Commencement Date
          multiplied by .00779782431.  Installments shall be made directly to
          Lender by electronic transfer of funds using the Automated Clearing
          House System.  All installments shall be applied first in payment of
          interest, calculated monthly on the unpaid principal balance, and the
          remainder of each installment shall be applied in payment of
          principal.  The entire unpaid principal balance plus accrued

                                       2
<PAGE>

          interest thereon shall be due and payable on April 1, 2009 (the
          "Maturity Date").

               As used herein, "Amortization Period Commencement Date" means
          April 1, 2001.

          Borrower shall have the right, upon thirty (30) days advance written
notice, beginning on April 1, 2002 of making a partial prepayment (a "Partial
Prepayment") or a full prepayment (a "Full Prepayment") of this Note with a
prepayment fee.  A Partial Prepayment may only be made in connection with a
Partial Release (as hereinafter defined).  The prepayment fee represents
consideration to Lender for loss of yield and reinvestment costs and shall also
be payable whenever prepayment occurs as a result of a condemnation or sale
under threat of condemnation of all or substantially all of the Property.

In the event of a Full Prepayment, the fee shall be the greater of Yield
Maintenance or 1% of the outstanding principal balance of this Note.

In the event of a Partial Prepayment, the fee shall be equal to the product of
(i) a fraction, the numerator of which is the amount of principal being prepaid
and the denominator of which is the outstanding principal balance of this Note
immediately prior to such prepayment, and (ii) the prepayment fee that would be
payable if there were a Full Prepayment at such time.

As used herein, "Yield Maintenance" means the amount, if any, by which

          (i)  the present value of the Then Remaining Payments (as hereinafter
               defined) calculated using a periodic discount rate (corresponding
               to the payment frequency under this Note) which, when compounded
               for such number of payment periods in a year, equals the per
               annum effective yield of the Most Recently Auctioned United
               States Treasury Obligation having a maturity date equal to the
               Maturity Date (or, if there is no such equal maturity date, then
               the linearly interpolated per annum effective yield of the two
               Most Recently Auctioned United States Treasury Obligations having
               maturity dates most nearly equivalent to the Maturity Date) as
               reported by The Wall Street Journal five business days prior to
                           -----------------------
               the date of prepayment; exceeds

          (ii) the outstanding principal balance of this Note (exclusive of all
               accrued interest).

                                       3
<PAGE>

If such United States Treasury obligation yields shall not be reported as of
such time or the yields as of such time shall not be ascertainable, then the
periodic discount rate shall be equal to the Treasury Constant Maturity Series
yields reported, for the latest day for which such yields shall have been so
reported, as of five business days preceding the prepayment date, in Federal
Reserve Statistical Release H.15 (519) (or any comparable successor publication)
for actively traded United States Treasury obligations having a constant
maturity most nearly equivalent to the Maturity Date.

          All parties at any time liable, whether primarily or secondarily, for
payment of indebtedness evidenced hereby, for themselves, their heirs, legal
representatives, successors and assigns, respectively, expressly waive
presentment for payment, notice of dishonor, protest, notice of protest, and
diligence in collection; consent to the extension by Lender of the time of said
payments or any part thereof; further consent that the Property or any part
thereof may be released by Lender, without in any way modifying, altering,
releasing, affecting, or limiting their respective liability or the lien of the
Lien Instrument; and agree to pay reasonable attorneys' fees and expenses of
collection in case this Note is placed in the hands of an attorney for
collection or suit is brought hereon and any attorneys' fees and expenses
incurred by Lender to enforce or preserve its rights under any of the Loan
Documents (as defined in the Lien Instrument) in any bankruptcy or insolvency
proceeding.

          Any principal, interest or other amounts payable under any of the Loan
Documents, not paid when due (without regard to any notice and/or cure
provisions contained in any of the Loan Documents), including principal becoming
due by reason of acceleration by Lender of the entire unpaid balance of this
Note, shall bear interest from the due date thereof until paid at the Default
Rate.  As used herein, "Default Rate" means the lower of a rate equal to the
interest rate in effect at the time of the default as herein provided plus 5%
per annum or the maximum rate permitted by law.

          No provision of this Note shall require the payment or permit the
collection of interest, including any fees paid which are construed under
applicable law to be interest, in excess of the maximum permitted by law.  If
any such excess interest is collected or herein provided for, or shall be
adjudicated to have been collected or be so provided for herein, the provisions
of this paragraph shall govern, and Borrower shall not be obligated to pay the
amount of such interest to the extent that it is in excess of the amount
permitted by law.  Any such excess collected shall, at the option of Lender,
unless otherwise required by applicable law, be immediately refunded to Borrower
or credited on the principal of this Note immediately upon Lender's awareness of
the collection of such excess.

                                       4
<PAGE>

          Notwithstanding any provision contained herein or in the Lien
Instrument to the contrary, if Lender shall take action to enforce the
collection of the indebtedness evidenced hereby or secured by the Lien
Instrument (collectively, the "Indebtedness"), its recourse, except as provided
below, shall be limited to the Property or the proceeds from the sale of the
Property, the proceeds from the sale of the assets of Borrower, and the proceeds
realized by Lender in exercising its rights and remedies (i) under the Absolute
Assignment (as defined in the Lien Instrument), (ii) under the Guarantee of
Recourse Obligations of even date herewith executed by CarrAmerica Realty
Corporation for the benefit of Lender, (iii) under any of the other Loan
Documents (as defined in the Lien Instrument) and (iv) in any other collateral
securing the Indebtedness.  If such proceeds are insufficient to pay the
Indebtedness, Lender will never institute any action, suit, claim or demand in
law or in equity against the partners of Borrower for or on account of such
deficiency; provided, however, that the provisions contained in this paragraph

          (i)  shall not in any way affect or impair the validity or
               enforceability of the Indebtedness or the Lien Instrument; and

          (ii) shall not prevent Lender from seeking and obtaining a judgment
               against the general partner(s) of Borrower as well as Borrower,
               and the general partner(s) of Borrower as well as Borrower shall
               be personally liable, for the Recourse Obligations.

As used herein, the term "Recourse Obligations" means

          (a) Rents and other income from the Property from and after the date
          which is forty-five (45) days prior to the occurrence of an Event of
          Default, which Event of Default remains uncured prior to the
          foreclosure sale of the Property pursuant to the Lien Instrument or
          the conveyance of the Property to Lender in lieu of foreclosure, which
          rents and other income have not been applied to the payment of
          principal and interest on this Note or to reasonable operating
          expenses of the Property,

          (b) Amounts necessary to repair any damage to the Property caused by
          the intentional acts or omissions of Borrower or those acting on
          behalf of Borrower,

          (c) Insurance loss and condemnation proceeds released to Borrower but
          not applied in accordance with any agreement between Borrower and
          Lender as to their application and consistent with the terms and
          provisions of the Lien Instrument,

                                       5
<PAGE>

          (d) The amount of insurance loss proceeds which would have been
          available with respect to a casualty on the Property, but were not
          available due to the default by Borrower in carrying all insurance
          required by Lender,

          (e) Damages suffered by Lender as a result of fraud or
          misrepresentation in connection with the Indebtedness by Borrower or
          any other person or entity acting on behalf of Borrower,

          (f) Amounts necessary to pay real estate taxes, special assessments
          and insurance premiums with respect to the Property either paid by
          Lender and not reimbursed prior to, or remaining due or delinquent on,
          either (i) the later of (A) the date on which title vests in the
          purchaser at the foreclosure sale of the Property pursuant to the Lien
          Instrument or (B) the date on which Borrower's statutory right of
          redemption shall expire or be waived or (ii) the date of the
          conveyance of the Property to Lender in lieu of foreclosure, and

          (g) All outstanding amounts due under the Indebtedness, including
          principal, interest, and other charges if there shall be a violation
          of any of the provisions of the Lien Instrument following the caption
          entitled "Due on Sale".

Payment of Debt.  Grantor agrees to pay the indebtedness hereby secured (the
- ---------------
"Indebtedness") promptly and in full compliance with the terms of the Loan
Documents.

Ownership.  Grantor represents that it owns the Property and has good and lawful
- ---------
right to convey the same and that the Property is free and clear from any and
all encumbrances whatsoever, except as appears in the title commitment accepted
by Beneficiary.  Grantor does

                                       5
<PAGE>

hereby forever warrant and shall forever defend the title and possession thereof
against the lawful claims of any and all persons whomsoever.

Maintenance of Property and Compliance with Laws.  Grantor agrees to keep the
- ------------------------------------------------
buildings and other improvements now or hereafter erected on the Land in good
condition and repair; not to commit or suffer any waste; to comply in all
material respects with all laws, rules and regulations affecting the Property;
and to permit Beneficiary to enter at all reasonable times for the purpose of
inspection and of conducting, in a reasonable and proper manner, such tests as
Beneficiary determines to be necessary in order to monitor Grantor's compliance
with applicable laws and regulations regarding hazardous materials affecting the
Property.

Insurance.  Grantor agrees to keep the Property insured for the protection of
- ---------
Beneficiary and Beneficiary's wholly owned subsidiaries and agents in such
manner, in such amounts and in such companies as Beneficiary may from time to
time approve, and to keep the policies therefor, properly endorsed, on deposit
with Beneficiary, or at Beneficiary's option, to keep certificates of insurance
(Acord 27 for all property insurance and Acord 25-S for all liability insurance)
evidencing all insurance coverages required hereunder on deposit with
Beneficiary, which certificates shall provide at least thirty (30) days notice
of cancellation to Beneficiary and shall list Beneficiary as the certificate
holder, that insurance loss proceeds from all property insurance policies,
whether or not required by Beneficiary, (less expenses of collection) shall, at
Beneficiary's option, be applied on the Indebtedness, whether due or not, or to
the restoration of the Property, or be released to Grantor, but such application
or release shall not cure or waive any default under any of the Loan Documents.
If Beneficiary elects to apply the insurance loss proceeds on the Indebtedness,
no prepayment privilege fee shall be due thereon.

Notwithstanding, the foregoing provision, Beneficiary agrees that if the
insurance loss proceeds are less than the unpaid principal balance of the Note
and if the casualty occurs prior to the last three years of the term of the
Note, then the insurance loss proceeds (less expenses of collection) shall be
applied to restoration of the Property to its condition prior to the casualty,
subject to satisfaction of the following conditions:

          (a)       There is no existing Event of Default at the time of
               casualty, and if there shall occur any Event of Default after the
               date of the casualty, Beneficiary shall have no further
               obligation to release insurance loss proceeds hereunder.

          (b)       The casualty insurer shall not have denied liability for
               payment of insurance loss proceeds as a result of any act,
               neglect, use or occupancy of the Property by Grantor or any
               tenant of the Property.

          (c)       Beneficiary shall be satisfied that all insurance loss
               proceeds so held, together with supplemental funds received from
               Grantor, shall be sufficient to complete the restoration of the
               Property. Any remaining insurance loss proceeds may, at the
               option of Beneficiary, be applied on the Indebtedness, whether or
               not due, or be released to Grantor.

          (d)       If required by Beneficiary, Beneficiary shall be furnished a
               satisfactory

                                       6

               report addressed to Beneficiary from an environmental engineer or
               other qualified professional satisfactory to Beneficiary to the
               effect that no adverse environmental impact to the Property
               resulted from the casualty.

          (e)       Beneficiary shall release casualty insurance proceeds as
               restoration of the Property progresses provided that Beneficiary
               is furnished satisfactory evidence of the costs of restoration
               and if, at the time of such release, there shall exist no
               Monetary Default (as hereinafter defined) and no default under
               the Loan Documents with respect to which Beneficiary shall have
               given Grantor notice pursuant to the Notice of Default provision
                                                    -----------------
               herein. If the estimated cost of restoration exceeds $250,000.00,
               (i) the drawings and specifications for the restoration shall be
               approved by Beneficiary in writing prior to commencement of the
               restoration, and (ii) Beneficiary shall receive an administration
               fee equal to 1% of the cost of restoration.

          (f)       Prior to each release of funds, Grantor shall obtain for the
               benefit of Beneficiary an endorsement to Beneficiary's title
               insurance policy insuring Beneficiary's lien as a first and valid
               lien on the Property subject only to liens and encumbrances
               theretofore approved by Beneficiary.

          (g)       Grantor shall pay all reasonable costs and expenses incurred
               by Beneficiary, including, but not limited to, outside legal
               fees, title insurance costs, third-party disbursement fees,
               third-party engineering reports and inspections deemed necessary
               by Beneficiary.

          (h)       All reciprocal easement and operating agreements, if any,
               benefiting the Property shall remain in full force and effect
               between the parties thereto on and after restoration of the
               Property.

          (i)       Beneficiary shall be satisfied that Projected Debt Service
               Coverage of at least 1.3 will be produced from the leasing of not
               more than 93% of the rentable square feet of space to former
               tenants or approved new tenants with leases satisfactory to
               Beneficiary for terms of at least five (5) years to commence not
               later than thirty (30) days following completion of such
               restoration ("Approved Leases").

          (j)       All leases in effect at the time of the casualty with
               tenants who have entered into Beneficiary's form of Non-
               Disturbance and Attornment Agreement or similar agreement shall
               remain in full force, subject to the terms of such leases, and
               each tenant thereunder shall be obligated, or shall elect, to
               continue the lease term at full rental (subject only to
               abatement, if any, during any period in which the Property or a
               portion thereof shall not be used and occupied by such tenant as
               a result of the casualty).

As used herein. "Projected Debt Service Coverage" means a number calculated by
dividing Projected Operating Income Available for Debt Service for the first
fiscal year following restoration of the Property by the debt service during the
same fiscal year under all indebtedness

                                       7
<PAGE>

secured by any portion of the Property. For purposes of the preceding sentence,
"debt service" means the greater of (x) debt service due under all such
indebtedness during the first fiscal year following completion of the
restoration of the Property or (y) debt service that would be due and payable
during such fiscal year if all such indebtedness were amortized over twenty-five
(25) years (whether or not amortization is actually required) and if interest on
such indebtedness were due as it accrues at the face rate shown on the notes
therefor (whether or not interest payments based on such face rates are
required).

"Projected Operating Income Available for Debt Service" means projected gross
annual rent from the Approved Leases for the first full fiscal year following
completion of the restoration of the Property less:

     (A)  the operating expenses of the Property for the last fiscal year
          preceding the casualty or the Taking, as the case may be;

     (B)  a replacement reserve for future tenant improvements, leasing
          commissions and structural items based on not less than $3.10 per
          rentable square foot at the Property per annum;

     (C)  the amount, if any, by which actual gross income during such fiscal
          period exceeds that which would be earned from the rental of 93% of
          the gross leasable area in the Property;

     (D)  the amount, if any, by which the actual management fee is less than
          3.0% of gross revenue during such fiscal period;

     (E)  the amount, if any, by which the actual real estate taxes are less
          than $3.75 per rentable square foot at the Property per annum; and

     (F)  the amount, if any, by which total operating expenses, excluding real
          estate taxes and replacement reserves, are less than $7.50 per
          rentable square foot at the Property per annum.

All projections referenced above shall be calculated in a manner satisfactory to
Beneficiary.

Condemnation.  Grantor hereby assigns to Beneficiary all Condemnation Proceeds.
- ------------
As used herein "Condemnation Proceeds" means all awards and any other proceeds
resulting from damage to, the taking of, or any sale or transfer in lieu of a
taking of, all or any portion of the Property in connection with condemnation
proceedings, the exercise of any power of eminent domain or the threat thereof
(a "Taking") less reasonable expenses of collection by Grantor or Beneficiary.
Condemnation Proceeds shall, at Beneficiary's option, be applied on the
Indebtedness in such manner as Beneficiary shall determine, whether due or not,
or to the restoration of the Property, or be released to Grantor, but such
application or release shall not cure or waive any default under any of the Loan
Documents.  No application of Condemnation Proceeds to the Indebtedness shall
reduce any monthly payments under the Note, and any application by Beneficiary
against principal shall be in inverse order of when due.  No

                                       8
<PAGE>

application by Beneficiary of Condemnation Proceeds to the Indebtedness shall,
except for a Taking of all or substantially all of the Property, require the
payment of a prepayment fee.

Notwithstanding the foregoing provision, Beneficiary agrees that if there shall
be a Taking of less than all or substantially all of the Property, the
restoration or replacement of the improvements on the Land to their functional
and economic utility prior to such Taking is possible and the Condemnation
Proceeds from such Taking are received prior to the last three years of the term
of the Note, such Condemnation Proceeds shall be applied to restoration of the
Property substantially to its condition prior to the Taking or to such other
condition desired by Grantor and approved by Beneficiary, subject to
satisfaction of the following conditions:

          (a)       There shall be no existing Event of Default (as hereinafter
               defined) at the time of the Taking, and if there shall occur any
               Event of Default after the date of the Taking, Beneficiary shall
               have no further obligation to release Condemnation Proceeds
               hereunder.

          (b)       Beneficiary shall be satisfied that all Condemnation
               Proceeds so held, together with supplemental funds to be made
               available by Grantor, shall be sufficient to complete the
               restoration of the Property. Any remaining Condemnation Proceeds
               may, at the option of Beneficiary, be applied on the
               Indebtedness, whether or not due, or be released to Grantor.

          (c)       Beneficiary shall release Condemnation Proceeds as
               restoration of the Property progresses if Beneficiary is
               furnished satisfactory evidence of the costs of restoration and,
               at the time of such release, there shall exist no default under
               the Loan Documents or the Ground Lease with respect to which
               Beneficiary shall have given Grantor notice pursuant to the Event
                                                                           -----
               of Default provision. If the estimated cost of restoration
               ----------
               exceeds $250,000, (i) the drawings and specifications for the
               restoration shall be approved by Beneficiary in writing prior to
               commencement of the restoration and (ii) Beneficiary shall
               receive an administration fee equal to 1% of the cost of
               restoration.

          (d)       Prior to each release of funds, Grantor shall obtain for the
               benefit of Beneficiary an endorsement to Beneficiary's title
               insurance policy insuring Beneficiary's lien as a first and valid
               lien on the Property subject only to liens and encumbrances
               theretofore approved by Beneficiary.

          (e)       Grantor shall pay all reasonable costs and expenses incurred
               by Beneficiary, including, but not limited to, outside legal
               fees, title insurance costs, third-party disbursement fees,
               third-party engineering reports and inspections deemed necessary
               by Beneficiary.

          (f)       All reciprocal easement and operating agreements, if any,
               benefiting the Property shall remain in full force and effect
               between the parties thereto on and after restoration of the
               Property.

<PAGE>

          (g)       Beneficiary shall be satisfied that Projected Debt Service
               Coverage of at least 1.30 will be produced from the leasing of
               not more than 93% of the rentable square feet of space to former
               tenants or approved new tenants with Approved Leases.

          (h)       All leases in effect at the time of Taking with tenants who
               have entered into Beneficiary's form of Non-Disturbance and
               Attornment Agreement or similar agreement shall remain in full
               force and each tenant thereunder shall be obligated, or shall
               elect, to continue the lease term at full rental (subject only to
               abatement, if any, during any period in which the Property or a
               portion thereof shall not be used and occupied by such tenant as
               a result of the Taking).

Taxes and Special Assessments.  Grantor agrees to pay before delinquency all
- -----------------------------
taxes and special assessments of any kind that have been or may be levied or
assessed against the Property, this instrument, the Note or the Indebtedness, or
upon the interest of Trustee or Beneficiary in the Property, this instrument,
the Note or the Indebtedness, and to procure and deliver to Beneficiary the
official receipt of the proper officer showing timely payment of all such taxes
and assessments; provided, however, that Grantor shall not be required to pay
any such taxes or special assessments if the amount, applicability or validity
thereof shall currently be contested in good faith by appropriate proceedings
and funds sufficient to satisfy the contested amount have been deposited in an
escrow satisfactory to Beneficiary.

Personal Property.  With respect to the Personal Property, Grantor hereby
- -----------------
represents, warrants and covenants as follows:

     (a) Except for the security interest granted hereby, Grantor is, and as to
portions of the Personal Property to be acquired after the date hereof will be,
the sole owner of the Personal Property, free from any lien, security interest,
encumbrance or adverse claim thereon of any kind whatsoever. Grantor shall
notify Beneficiary of, and shall indemnify and defend Beneficiary and the
Personal Property against, all claims and demands of all persons at any time
claiming the Personal Property or any part thereof or any interest therein.

     (b) Except as otherwise provided above, Grantor shall not lease, sell,
convey or in any manner transfer the Personal Property without the prior consent
of Beneficiary.

     (c) Grantor maintains a place of business at the address set forth above in
this instrument, and Grantor shall immediately notify Beneficiary in writing of
any change in its place of business.

     (d) At the request of Beneficiary, Grantor shall Join Beneficiary in
executing one or more financing statements and continuations and amendments
thereof pursuant to the Uniform Commercial Code of the jurisdiction in which the
Property is located in form satisfactory to Beneficiary, and Grantor shall pay
the cost of filing the same in all public offices wherever filing is deemed by
Beneficiary to be necessary or desirable.

Other Liens.  Grantor agrees to keep the Property free from all other mortgage
- -----------
liens and from all liens prior to the lien created hereby.  The creation of any
other mortgage lien, whether or not

                                       10
<PAGE>

prior to the lien created hereby, the creation of any prior lien or the
assignment or pledge by Grantor of its revocable license to collect, use and
enjoy rents and profits from the Property shall constitute a default under the
terms of this instrument. The term "mortgage" includes a mortgage, deed of trust
deed to secure debt or any other security interest in the Property.

Leases.  Grantor represents and warrants that there is no assignment or pledge
- ------
of any leases of, or rentals or income from, the Property now in effect except
to Beneficiary; and covenants that, until the Indebtedness is fully paid, it (i)
shall not make any such assignment or pledge to anyone other than Beneficiary,
(ii) shall not, unless expressly permitted under another provision in this
instrument, make any assignment or pledge to anyone of its hereinafter described
revocable license to collect, use and enjoy the rents and profits, and (iii)
shall not, without the prior written approval of Beneficiary, consent to a
cancellation or surrender of any of said leases having at the time an unexpired
term of more than two years or to a release or reduction of the liability of any
party to such a lease.

In consideration of the Indebtedness, Grantor, pursuant to the Absolute
Assignment has assigned to Beneficiary all of Grantor's right title and interest
in said leases, including Grantor's right to collect, use and enjoy the rents
and profits therefrom. Beneficiary has, in the Absolute Assignment, granted to
Grantor a license to collect use and enjoy said rents and profits.  Such license
is revocable by Beneficiary pursuant to the terms of the Absolute Assignment.

Costs, Fees and Expenses.  Grantor agrees to pay all reasonable costs, fees and
- ------------------------
expenses of this trust; to appear in and defend any action or proceeding
purporting to affect the security hereof or the rights or powers of Beneficiary
or Trustee hereunder; to pay all reasonable costs and expenses, including the
cost of obtaining evidence of title and reasonable attorney's fees, incurred in
connection with any such action or proceeding; and to pay any and all reasonable
attorney's fees and expenses of collection and enforcement in the event the Note
is placed in the hands of an attorney for collection, enforcement of any of the
Loan Documents is undertaken or suit is brought thereon.

Failure of Grantor to Act.  If Grantor falls to make any payment or do any act
- -------------------------
as herein provided, Beneficiary or Trustee may, without obligation so to do,
without notice to or demand upon Grantor and without releasing Grantor from any
obligation hereof: (i) make or do the same in such manner and to such extent as
Beneficiary may deem necessary to protect the security hereof, Beneficiary or
Trustee being authorized to enter upon the Property for such purpose; (ii)
appear in and defend any action or proceeding purporting to affect the security
hereof, or the rights or powers of Beneficiary or Trustee; (iii) pay, purchase,
contest or compromise any encumbrance, charge or lien which in the judgment of
Beneficiary appears to be prior or superior hereto; and (iv) in exercising any
such powers, pay necessary reasonable expenses, employ counsel and pay its
reasonable fees.  Sums so expended shall be payable by Grantor immediately upon
demand with interest from date of expenditure at the Default Rate (as defined in
the Note).  All sums so expended by Beneficiary and the interest thereon shall
be included in the Indebtedness and secured by the lien of this instrument.

Event of Default; Cross Default.  Any default by Grantor in making any required
- -------------------------------
payment of the Indebtedness or any default in any provision, covenant, agreement
or warranty contained in

                                       11
<PAGE>

any of the Loan Documents shall, except as provided in the two immediately
succeeding paragraphs, constitute an "Event of Default". Any Event of Default
(as defined in the Cap 50 Lien Instrument) shall constitute an "Event of
Default" under this instrument, and Beneficiary, at its option, may declare the
Indebtedness due and payable at once, and may exercise or cause to be exercised
all its rights and remedies under this instrument and the Cap 50 Lien Instrument
concurrently or separately and in such order as Beneficiary may determine.

Notice of Default.  A default in any payment required in the Note or any other
- -----------------
Loan Document, whether or not payable to Beneficiary, (a "Monetary Default")
shall not constitute an Event of Default unless Beneficiary shall have given a
written notice of such Monetary Default to Grantor and Grantor shall not have
cured such Monetary Default by payment of all amounts in default (including
payment of interest at the Default Rate, as defined in the Note, from the date
of default to the date of cure on amounts owed to Beneficiary) within five (5)
business days after the date on which Beneficiary shall have given such notice
to Grantor.

Any other default under the Note or under any other Loan Document (a "Non-
Monetary Default") shall not constitute an Event of Default unless Beneficiary
shall have given a written notice of such Non-Monetary Default to Grantor and
Grantor shall not have cured such Non-Monetary Default within thirty (30) days
after the date on which Beneficiary shall have given such notice of default to
Grantor (or, if the Non-Monetary Default is not curable within such 30-day
period, Grantor shall not have (i) diligently undertaken and continued to pursue
the curing of such Non-Monetary Default and (ii) deposited an amount sufficient
to cure such Non-Monetary Default in an escrow account satisfactory to
Beneficiary).

For purposes of this provision, written notice may be delivered personally or
sent by certified mail or reputable courier service with charges prepaid, by
telecopier or by such other method whereby the receipt thereof may be confirmed.
Notice shall be deemed given on the date received.  Any notice which is
rejected, the acceptance of which is refused or which is incapable of being
delivered for any reason shall be deemed received as of the date of attempted
delivery.

In no event shall the notice and cure period provisions recited above constitute
a grace period for the purposes of commencing interest at the Default Rate (as
defined in the Note).

Substitution of Trustee.  Beneficiary and its successors and assigns may for any
- -----------------------
reason and at any time appoint a new or substitute Trustee by written
appointment delivered to such new or substitute Trustee without notice to
Grantor, without notice to, or the resignation or withdrawal by, the existing
Trustee and without recordation of such written appointment unless notice or
recordation is required by the laws of the jurisdiction in which the Property is
located.  Upon delivery of such appointment, the new or substitute Trustee shall
be vested with the same title and with the same powers and duties granted to the
original Trustee.

Appointment of Receiver.  Upon commencement of any proceeding to enforce any
- -----------------------
right under this instrument, including foreclosure thereof, Beneficiary (without
limitation or restriction by any present or future law, without regard to the
solvency or insolvency at that time of any party liable for the payment of the
Indebtedness, without regard to the then value of the Property, whether or not
there exists a threat of imminent harm, waste or loss to the Property and
whether

                                       12
<PAGE>

or not the same shall then be occupied by the owner of the equity of redemption
as a homestead) shall have the absolute right to the appointment of a receiver
of the Property and of the revenues, rents, profits and other income therefrom,
and said receiver shall have (in addition to such other powers as the court
making such appointment may confer) full power to collect all such income and,
after paying all necessary expenses of such receivership and of operation,
maintenance and repair of said Property, to apply the balance to the payment of
any of the Indebtedness then due.

Foreclosure.  Upon the occurrence of an Event of Default, the entire unpaid
- -----------
Indebtedness shall, at the option of Beneficiary, become immediately due and
payable for all purposes without any notice or demand, except as required by law
(ALL OTHER NOTICE OF THE EXERCISE OF SUCH OPTION, OR OF THE INTENT TO EXERCISE
- ------------------------------------------------------------------------------
SUCH OPTION, BEING HEREBY EXPRESSLY WAIVED), and Beneficiary may, in addition to
- -------------------------------------------
exercising any rights it may have with respect to the Personal Property under
the Uniform Commercial Code of the jurisdiction in which the Property is
located, institute proceedings in any court of competent jurisdiction to
foreclose this instrument as a mortgage, or to enforce any of the covenants
hereof, or Trustee or Beneficiary may, either personally or by agent or attorney
in fact, enter upon and take possession of the Property and may manage, rent or
lease the Property or any portion thereof upon such terms as Beneficiary may
deem expedient, and collect, receive and receipt for all rentals and other
income therefrom and apply the sums so received as hereinafter provided in case
of sale.  Trustee is hereby further authorized and. empowered, either after or
without such entry, to sell and dispose of the Property en masse or in separate
parcels (as Trustee may think best), and all the right, title and interest of
Grantor therein, by advertisement or in any manner provided by the laws of the
jurisdiction in which the Property is located, (GRANTOR HEREBY EXPRESSLY WAIVES
                                               --------------------------------
ANY RIGHT TO A HEARING PRIOR TO SUCH SALE), and to issue, execute and deliver a
- ------------------------------------------
deed of conveyance, all as then may be provided by law; and Trustee shall, out
of the proceeds or avails of such sale, after first paying and retaining all
fees, charges, costs of advertising the Property and of making said sale, and
attorneys' fees as herein provided, pay to Beneficiary or the legal holder of
the Indebtedness the amount thereof, including all sums advanced or expended by
Beneficiary or the legal holder of the Indebtedness, with interest from date of
advance or expenditure at the Default Rate (as defined in the Note), rendering
the excess, if any, as provided by law; such sale or sales and said deed or
deeds so made shall be a perpetual bar, both in law and equity, against Grantor,
the heirs, successors and assigns of Grantor, and all other persons claiming the
Property aforesaid, or any part thereof, by, from, through or under Grantor.
The legal holder of the Indebtedness may purchase the Property or any part
thereof, and it shall not be obligatory upon any purchaser at any such sale to
see to the application of the purchase money.

Due on Sale.  The present ownership and management of the Property is a material
- -----------
consideration to Beneficiary in making the loan secured by this instrument, and,
except as provided in provision hereof entitled "Partial Release", Grantor shall
                                                 ---------------
not (i) convey title to all or any part of the Property or (ii) enter into any
contract to convey (land contract/installment sales contract/contract for deed)
title to all or any part of the Property which gives a purchaser possession of,
or income from, the Property prior to a transfer of title to all or any part of
the Property ("Contract to Convey"), and CarrAmerica Realty Corporation, a
Maryland corporation (the "REIT") shall not convey or enter into any contract to
convey its interest in Grantor.

Financial Statements.  Grantor agrees to furnish to Beneficiary, at Grantor's
- --------------------
expense and within ninety (90) days after the close of each fiscal year
("Financial Statements Due Date"), the following:

     (A)  Annual audited financial statements for Grantor (unless such
          statements are consolidated with the audited financial statements of
          the REIT) and annual audited financial statements for the REIT
          (collectively, the "Statements"), prepared in accordance with
          generally accepted accounting principles by a "Big 5" firm or such
          other certified public accountant reasonably satisfactory to
          Beneficiary; and

     (B)  Annual operating statements for each Project, including a detailed
          line item breakdown of all operating expenses and a separate
          supplemental schedule listing the capitalized costs associated with
          tenant improvements, lease commissions and capital improvements
          (collectively referred to herein as the "Property Statements");

     (C)  A current rent roll (the "Rent Roll");

     (D   A certification (the "Certification") by a senior officer of the
          general partner of Grantor stating that the Property Statements and
          Rent Roll are true and correct and the Property Statements have been
          prepared in accordance with generally accepted accounting principles;
          and

     (E)  A copy of each lease (the "Leases") for space in excess of 10,000
          rentable square feet of space at the Property executed during the
          immediately preceding fiscal year.

Grantor acknowledges that Beneficiary requires the Statements, Property
Statements, Rent Roll, Leases and Certification in order to record accurately
the value of the Property for financial and regulatory reporting.

If Grantor does not furnish or cause to be furnished the Statements, Property
Statements, Rent Roll, Leases and Certification to Beneficiary by the Financial
Statements Due Date, within 30 days after Beneficiary shall have given written
notice to Grantor that the Statements, Property Statements, Rent Roll, Leases
and/or Certification have not been received as required,

     (x)  interest on the unpaid principal balance of the Indebtedness shall as
     of the Financial Statements Due Date, accrue and become payable at a rate
     equal to the sum of the Interest Rate (as defined the Note) plus one
     percent (1%) per annum (the "Increased Rate"); and

     (y)  Beneficiary may elect to obtain an independent appraisal and audit of
     the Property at Grantor's expense, and Grantor agrees that it will, upon
     request, promptly make Grantor's books and records regarding the Property
     available to Beneficiary and the person(s) performing the appraisal and
     audit (which obligation Grantor agrees can be

                                       14
<PAGE>

     specifically enforced by Beneficiary).

The amount of the payments due under the Note during the time in which the
Increased Rate shall be in effect shall be changed to an amount which, prior to
the Amortization Period Commencement Date (as defined in the Note), reflects the
Increased Rate and which, after the Amortization Period Commencement Date, is
sufficient to amortize the then unpaid principal balance at the Increased Rate
during the then remaining portion of a period of 25 years commencing with the
Amortization Period Commencement Date (as defined in the Note).  Interest shall
continue to accrue and be due and payable monthly at the Increased Rate until
the Statements, Property Statements, Rent Roll, Leases and Certification shall
be furnished to Beneficiary as required.  Commencing on the date on which the
Statements, Property Statements, Rent Roll, Leases and Certification are
received by Beneficiary, interest on the unpaid principal balance shall again
accrue at the Interest Rate and the payments due thereafter shall be changed to
an amount which prior to the Amortization Period Commencement Date, reflects
interest at the Interest Rate and which, after the Amortization Period
Commencement Date, is sufficient to amortize the then unpaid principal balance
at the Interest Rate during the then remaining portion of a period of 25 years
commencing with the Amortization Period Commencement Date.

Notwithstanding the foregoing, Beneficiary shall have the right to conduct an
independent audit at its own expense at any time, upon thirty (30) days prior
notice to Grantor, but not more than once annually unless an Event of Default
exists.

Partial Releases.  Upon written request from each obligor of the Note, a Project

     2)   Payment toward the unpaid principal balance of the Note due at final
          maturity in an amount equal to (i) the current outstanding principal
          balance of the Note less the Supportable Loan Amount, (ii) 1.10 times
          the Allocated Loan Amount for the Project to be released, or (iii) a
          lesser amount determined by Beneficiary, whichever of (i), (ii) or
          (iii) Beneficiary shall choose.

     3)   Payment of a Partial Prepayment (as defined in the Note) fee.

As used herein "Supportable Loan Amount" means an amount equal to the Net Income

<PAGE>

     B)   depreciation, if any, of fixed assets at or constituting the Remaining
          Property for such fiscal period;

     C)   amortization, if any, of standard tenant finish expenditures at the
          Remaining Property (but specifically excluding the amortization of
                                               ---------
          tenant finish expenditures by Grantor in excess of $30.00 per square
          foot for new tenants and $15.00 per square foot for renewal tenants
          (i.e., above standard tenant finishes), free rent and rent
          concessions); and

     D)   amortization of costs incurred in connection with any indebtedness
          secured by any portion of the Remaining Property and leasing
          commissions which have been prepaid; and

less the following:

     E)   a replacement reserve for future tenant improvements, leasing
          commissions and structural items based on not less than $3.10 per
          annum per rentable square foot of the Remaining Property;

     F)   the amount, if any, by which actual gross income during such fiscal
          period exceeds that which would have been earned from the rental of
          93% of the gross leasable area in the Remaining Property;

     G)   the amount, if any, by which the actual management fee is less than 3%
          of gross revenue from the Remaining Property during such fiscal
          period;

     H)   the amount, if any, by which the actual real estate taxes are less
          than $3.75 per square foot of the Remaining Property per annum; and


     I)   the amount, if any, by which total actual operating expenses,
          excluding real estate taxes and replacement reserves, are less than
          $7.50 per square foot of the Remaining Property per annum.

All adjustments to net income referred to above in clauses (A) through (I) shall
be calculated in a manner satisfactory to Beneficiary.

As used herein, "Remaining Property" means the Property less the Project to be
released.

For purposes of this provision, any required allocation of any adjustment to net
income [including the interest adjustment in clause (A)] shall be based on the
"Allocated Proportionate Share" for each Project, which shall be defined as
follows:

     ---------------------------------------------------------------------

the Allocated Proportionate Share and the outstanding principal balance of the
Note.

- ----------------------------------
Property, without the prior written consent of Beneficiary, to (i) dry cleaning
operations that perform dry cleaning on site with chlorinated solvents or (ii)
any other tenants that use chlorinated solvents in the operation of their

Readiness Status Report.  Grantor agrees that it will comply with its report
- -----------------------
with respect to the Property's Year 2000 compliance reports furnished to
Beneficiary prior to the date hereof (the "Readiness Status Report") in all
material respects.  Notwithstanding anything to the contrary herein, any
equipment failure that does not have a material impact on the operations of the
Property or that does not impact the rental income of the Property shall not
constitute a breach of this provision.

Deposits by Grantor.  To assure the timely payment of real estate taxes and
- -------------------
special assessments (including personal property taxes. if appropriate),
Beneficiary shall have the option, upon the occurrence of an Event of Default,
to require Grantor to deposit funds with Beneficiary in monthly or other
periodic installments in amounts estimated by Beneficiary from time to time
sufficient to pay real estate taxes and special assessments as they become due.
If at any time the funds so held by Beneficiary shall be insufficient to pay any
of said expenses, Grantor shall, upon receipt of notice thereof, immediately
deposit such additional funds as may be necessary to remove the deficiency.  All
funds so deposited shall be irrevocably appropriated to Beneficiary to be
applied to the payment of such real estate taxes and special assessments and, at
the option of Beneficiary after default, the Indebtedness.

Liens Discharged by Proceeds.  Beneficiary shall be subrogated to the lien of
- ----------------------------
any and all prior encumbrances, liens or charges paid and discharged from the
proceeds of the Note, and even though said prior liens have been released of

of the Property affected thereby to the extent of such payments, respectively.

Modification of Terms.  Without affecting the liability of Grantor or any other
- ---------------------
person (except any person expressly released in writing) for payment of the
Indebtedness or for performance of any obligation contained herein and without

released in writing, Beneficiary may. at any tune and from time to time, either

- -------------------
any of the other Loan Documents, Beneficiary is given any option, such option
may be exercised when the right accrues, or at any time thereafter, and no
acceptance by Beneficiary of payment of Indebtedness in default shall constitute
a waiver of any default then existing and continuing or thereafter occurring.

Nature and Succession of Agreements.  Each of the provisions, covenants and
- -----------------------------------
agreements contained herein shall inure to the benefit of, and be binding on,
the successors, grantees, and assigns of the parties hereto, respectively, and

pay the amount of such interest or other obligation to the extent that it is in
excess of the amount permitted by law.

- -----------------------
contrary, the personal liability of the partners in Grantor shall be limited as
