PART I

Item 1. BUSINESS

General

CarrAmerica Realty, L.P. is a Delaware limited partnership formed in March 1996 for the purpose of owning, acquiring, developing and operating office buildings across the United States. As of December 31, 2005,
we owned a controlling interest in a portfolio of 53 operating office buildings. The 53 operating office buildings contain a total of approximately 4.1 million square feet of net rentable area and as of December 31, 2005 were 91.4% leased.
As of December 31, 2005, we also owned minority interests (ranging from 21.2% to 49.0%) in 30 operating office buildings. The 30 operating office buildings in which we owned a minority interest as of December 31, 2005 contained a total of
approximately 3.3 million square feet of net rentable area and were 95.3% leased.

We are managed indirectly by CarrAmerica Realty
Corporation, a fully integrated, self-administered and self-managed publicly traded real estate investment trust (REIT), which is listed on the New York Stock Exchange under the symbol CRE.

On June 30, 2004, CarrAmerica Realty Corporation contributed substantially all of it assets to CarrAmerica Realty Operating Partnership, L.P. in
exchange for units of common and preferred partnership interest in CarrAmerica Realty Operating Partnership, L.P. CarrAmerica Realty Operating Partnership, L.P. assumed substantially all of CarrAmerica Realty Corporations liabilities
(CarrAmerica Realty Corporation and CarrAmerica Realty Operating Partnership, L.P. are collectively referred to hereafter as CarrAmerica). Our general partner is CarrAmerica Realty GP Holdings, LLC. (General Partner), a
wholly owned subsidiary of CarrAmerica. Our General Partner owned a 1.0% interest in us at December 31, 2005. Our limited partners are CarrAmerica Realty LP Holdings, LLC, a wholly owned subsidiary of CarrAmerica, which owned an approximate
92.5% interest in us at December 31, 2005, and various other individuals and entities, which collectively owned an approximate 6.5% interest in us at December 31, 2005.

CarrAmerica focuses on the acquisition, development, ownership and operation of office properties, located primarily in selected markets across the
United States. As of December 31, 2005, it owned a controlling interest in 235 operating office buildings. The 235 operating office buildings contain a total of approximately 18.4 million square feet of net rentable area. The operating
buildings in which it owned a controlling interest as of December 31, 2005 were 89.4% leased and, in the aggregate, had approximately 1,254 tenants. As of December 31, 2005, CarrAmerica also owned minority interests (ranging from 15% to
50%) in 50 operating office buildings and one development property. These 50 operating office buildings contain a total of approximately 7.9 million square feet of net rentable area, while it is estimated that the development property, which is
currently under construction, will contain approximately 154,000 square feet of net rentable area. The operating buildings in which CarrAmerica owned a minority interest as of December 31, 2005 were 91.4% leased. For more complete information
regarding CarrAmerica, see CarrAmericas Annual Report on Form 10-K for the year ended December 31, 2005 (the 2005 CarrAmerica 10-K).

CarrAmerica or its predecessor, The Oliver Carr Company (OCCO), have developed, owned and operated office buildings in the Washington, D.C. metropolitan area for more than 40 years.

CarrAmerica organized and administers us as a means of acquiring, developing, owning and operating certain properties in its portfolio. All of our
properties, along with our financial condition and results of operations, are reported as part of the consolidated financial statements of CarrAmerica. We are required to report separately in this Annual Report on Form 10-K and other periodic
reports filed with the Securities and Exchange Commission because we are a guarantor of CarrAmericas publicly held debt. As of December 31, 2005, approximately 22.4% of the total assets of CarrAmerica were owned by us or our subsidiaries.

We contract with CarrAmerica for services. During 2005, CarrAmerica charged us for the compensation costs of approximately 41 on-site
employees. The compensation cost charged to us by

Business Strategy

Our primary business is real estate property operations. We are an integral part of CarrAmerica, and our operations and strategic direction are defined
by CarrAmerica. CarrAmericas primary business objectives are to achieve long-term sustainable per share earnings and cash flow growth and to maximize stockholder value by acquiring, developing, owning and operating office properties primarily
in markets throughout the United States that exhibit strong, long-term growth characteristics. CarrAmerica believes that it utilizes its knowledge of its markets to evaluate market conditions and determine whether those conditions favor acquisition,
development or disposition of assets. During the last five years, CarrAmerica has actively deployed capital towards acquisitions and development in order to create a portfolio with strong long-term growth prospects. In addition to seeking growth
through acquisitions and development, CarrAmerica continues to strive to retain tenants and attract new tenants in its existing portfolio. CarrAmerica believes that its focus on its local relationships in its core markets, on customer service,
primarily through superior property management and fast and responsive leasing initiatives has enabled it to maintain strong portfolio performance in a challenging office market.

Each of CarrAmericas markets is managed by a Marketing Managing Director (MMD), who is responsible for maximizing returns on
CarrAmericas portfolio and pursuing investment, development, and service opportunities. MMDs ensure that CarrAmerica consistently meets the needs of its customers, identifying new growth or capital deployment opportunities and sustaining
active relationships with real estate brokers. Because of their ties and experience in the local markets, MMDs have extensive knowledge of local conditions in their respective markets and are an important part of building CarrAmericas local
operations and investment strategies.

2005 Activity

After several years of adverse conditions in the commercial office real estate markets, vacancy rates peaked in the majority of our markets in 2003 and then began to improve. At the end of 2005, vacancy rates in all
of our markets were declining due to continuing positive net absorption. As a result of improved office job growth, we believe leasing activity is up significantly, and we believe that market rental rates have stabilized in all of our markets and
have improved in many of our markets, including Washington, D.C. and Southern California. We anticipate rental economics will improve in the majority of our markets in 2006.

As a result of the improving market conditions described above, occupancy in our portfolio of operating properties increased to 91.4% at
December 31, 2005 compared to 87.8% at December 31, 2004. If demand continues to improve in 2006, we expect our average occupancy may improve further. Our occupancy also improved in 2005 over 2004 due to acquisitions of properties with
higher occupancies, dispositions of certain low occupancy properties and improving rental markets. We earned $1.6 million of lease termination fees in 2005 compared to $0.6 million in 2004. These fees are non-recurring in nature and we cannot
determine at this time what termination fees, if any, we will generate in 2006.

Not withstanding the improving markets for office space
and declining vacancy rates in most of our markets, rental rates for in-place leases in certain markets remain significantly above current market rental rates. While we believe that market rental rates have stabilized and are improving in many of
our markets, rental rates on in-place leases in certain markets remain significantly above current market rental rates. We estimate that market rental rates on leased space expiring in 2006 will be, on average, approximately 10%-12% lower than
straight-lined rents on our expiring leases. We have 198,000 square feet of space on which leases are currently scheduled to expire in 2006.

We have decided, based on current returns and other market factors to market for sale our wholly-owned properties in the Chicago and Denver markets, and we have begun these efforts in the first quarter of 2006. We intend to reinvest the
proceeds from the disposition of any of these properties in our other markets, where we believe we will recognize a greater return on our invested capital and for general corporate purposes. There can be no assurance that these dispositions will be
consummated on favorable terms, if at all. The properties did not meet our criteria to be classified as held for sale for financial reporting purposes at December 31, 2005. A summary of the net book value of the assets and the operating results
of our Chicago and Denver properties, as of and for the twelve months ended December 31, 2005, is as follows:

Disposition Activity

During 2005 we disposed of our
Phoenix portfolio, 2600 West Olive, Two Mission and the Quorum buildings in Dallas, resulting in proceeds of approximately $158.3 million and recognized gains of $16.7 million. During 2005, we recognized an impairment loss of $6.7 million in 2005 in
connection with these properties during the year. For each of the sales, we have had no continuing involvement with any of the properties and accordingly, the gains on these sales, the impairment losses and the operating results of each property are
classified as discontinued operations.

Acquisition Activity

During 2005 we acquired four operating properties from third parties, North Creek Corporate Center, Park Place Office Tower, West Willows Technology Center and Chancellor Park. The acquired properties totaled
approximately 608,489 rentable square feet and our investment was approximately $167.2 million.

Joint Ventures and Development Activities

Joint venture arrangements provide us with opportunities to reduce investment risk by diversifying capital deployment and enhancing returns on invested
capital from fee arrangements. We did not enter into any new joint ventures or have any development activity during 2005.

Item 1A. 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 units. Any of these risks or the occurrence of any one or more of the
uncertainties described below could have a material adverse effect on our financial condition and the performance of our business.

Our performance and
unit value are subject to risks associated with the real estate industry

We derive a substantial majority of our operating and net
income from the ownership and operation of office buildings. If we do not generate income sufficient to meet our operating expenses, including debt service and capital expenditures necessary to maintain or improve our properties, our financial
performance, the value of our real estate assets and our ability to pay distributions to our unitholders, and consequently the value of our units, will be adversely affected. We are susceptible to, among others, the following real estate industry
risks:



| |  |  | Downturns in the national, regional and local economic conditions where our properties are located, which generally will negatively impact the demand for office space and rental
rates;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Local conditions such as an oversupply of office properties, including space available by sublease, or a reduction in demand for high rise and other office properties, making it
more difficult for us to lease space at attractive rental rates, or at all;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Competition from other available office properties, which could cause us to lose current or prospective tenants to other properties or cause us to reduce our rental rates;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Changes in market rental rates and our ability to fund repair and maintenance costs;
| | - |  | ------------------------------------------------------------------------------------



| |  |  | Our ability to fund the cost of tenant improvements, leasing commissions and other costs associated with leasing or re-letting space;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Earthquakes and other natural disasters, terrorist acts, civil disturbances or acts of war which may result in uninsured or underinsured losses;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Our ability to collect rent from tenants; and
| | - |  | ---------------------------------------------



| |  |  | Our ability to pay for adequate maintenance, insurance, utility, security and other operating costs, including real estate taxes and debt service payments, that are not necessarily
reduced when circumstances such as market factors and competition cause a reduction in income from a property.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Expected shortfalls in
CarrAmericas cash flow from operations could require them to draw on their line of credit or dispose of properties in order to meet their anticipated obligations and also may cause them to slow their development activity and/or limit their
ability to declare and pay dividends at their current rate

We are primarily funded by CarrAmerica. CarrAmerica anticipates that their
cash flow from operations will be adversely affected in 2006 by declining rental rates in certain of their markets with expiring leases, particularly in Northern California, rent abatement features in many of the new leases at their properties and,
most significantly, their estimated tenant-related and other capital expenditures associated with new leases. They anticipate that, in order to maintain their expected quarterly dividend, they will be required to fund a shortfall of cash from
operations of approximately $75 to $90 million in 2006. In order to satisfy this shortfall, they currently expect to be required to borrow under their line of credit and/or dispose of properties they otherwise would choose not to sell. Any
borrowings under their line of credit to fund these shortfalls would reduce the amount of funds available for other purposes, such as potential acquisitions, capital improvements or development activities.

---

##### Table of Contents

In addition, CarrAmericas ability to borrow under their line of credit to fund these anticipated
levels of tenant and other capital expenditures and to pay their expected dividend may be limited by the terms of their debt covenants. During 2006, CarrAmerica expects to approach the limit of their unencumbered leverage ratio which restricts
unsecured debt outstanding to no more than 60% of unencumbered assets. As of December 31, 2005, their unencumbered leverage ratio was 56.7%. Their unencumbered leverage ratio is most significantly impacted by the performance of their operating
properties and net borrowings required to fund capital expenditures and pay their dividend as a result of insufficient operating cash flow. Incurring additional unsecured debt to acquire additional unencumbered assets does not impact their
unencumbered leverage ratio as significantly as incurring additional debt for other purposes. The tangible fair market value of their unencumbered properties is calculated by applying capitalization rates stipulated in their line of credit of 8.5% -
9.0% to current operating income. Therefore, CarrAmericas unencumbered leverage ratio could increase if the operating income of their unencumbered properties decreases. Additionally, the ratio will increase as they acquire properties which
have operating income which is lower than 8.5% - 9.0% of the amount invested. The additional debt required to fund their expected shortfall may result in them exceeding this limit.

Declines in overall economic activity, particularly in our core markets, could adversely affect our operating results

For several years, a weak economic climate affected the office real estate markets. At the end of 2005, vacancy rates in all of our markets were declining and rental economics slowly improving.

Rental rates on space that was re-leased in 2005, generally decreased in comparison to rates that were in effect under expiring leases. While market
rental rates have stabilized and are improving in many of our markets, rental rates on in-place leases in certain markets, particularly in our Northern California market, remain significantly above current market rental rates. We estimate that
market rental rates on leased space expiring in 2006 will be, on average, approximately 10%-12% lower than straight-lined rents on expiring leases. We have 198,000 square feet of space on which leases are currently scheduled to expire in 2006.

We are particularly subject to the economic risks in our Washington, DC Metro Area, Northern California and Southern California core
markets. These markets represented approximately 26.9%, 15.7%, and 13.7%, respectively, of our property operating income in 2005. A downturn in the economies of these markets, or the impact of a continued national economic downturn on these markets,
could result in reduced demand for office space and decreasing rental rates.

One of the factors contributing to the decline in occupancy
for our office properties was the increased level of early lease terminations. Future rental income may be affected by future lease terminations as we are unlikely to be able to collect upon termination the full contracted amount payable under the
leases as well as the additional cost of re-leasing the space.

Further decreases in occupancy rates and/or further declines in rental
rates, particularly in our Washington, DC Metro Area, Northern California and Southern California core markets, may adversely affect our revenues and results of operations in subsequent periods, which could have a material adverse effect on our
liquidity and financial condition, our ability to make distributions to our unitholders and result in a decline in the market value of our units.

We
may be unable to renew leases or relet space on similar terms, or at all, as leases expire or are terminated, or may expend significant capital in our efforts to relet space

From 2006 through 2010, leases representing approximately 53.8% of our rentable square feet at our currently stabilized properties will expire, with
leases on at least 4.8% of our rentable square feet expiring in each of those years. We may not be able to renew leases with our existing tenants or we may be unable to relet space to new tenants if our current tenants do not renew their leases or
terminate their leases early. Even if our tenants renew their leases or we are able to relet the space, the terms and other costs of renewal or reletting, including the cost of required renovations, increased tenant improvement allowances, leasing
commissions, declining rental rates and other potential concessions may be less favorable or more

costly than the terms of our current leases or than we anticipate and could require the expenditure of significant amounts of capital. If we are unable to
renew leases or relet space in a reasonable time, or if rental rates decline or tenant improvement, leasing commissions and other costs increase, it could have a material adverse effect on our results of operations, liquidity and financial condition
and result in a decline in the value of our units.

Our properties face significant competition which may impede our ability to retain tenants or re-let
space when existing tenants vacate

We face significant competition from other owners, operators and developers of office properties,
many of which own properties similar to ours in the markets in which we operate. Such competition may affect our ability to attract and retain tenants and reduce the rents we are able to charge. These competing properties may have vacancy rates
higher than our properties, which may result in their owners being willing to rent space at lower rental rates than we or in their owners providing greater tenant improvement allowances or other leasing concessions. This combination of circumstances
could adversely affect our results of operations, liquidity and financial condition, which could cause a decline in the value of our units.

We face
potential adverse effects from tenant delinquencies, bankruptcies or insolvencies

The bankruptcy, insolvency or other failure to pay of
our tenants is likely to adversely affect the income produced by our properties. If a tenant defaults, we may experience delays and incur substantial costs in enforcing our rights as landlord. If a tenant files for bankruptcy, we may not be able to
evict the tenant solely because of such bankruptcy or failure to pay. A court, however, may authorize a tenant to reject and terminate its lease with us. In such a case, our claim against the tenant for unpaid, future rent would be subject to a
statutory cap that might be substantially less than the remaining rent owed under the lease. In addition, certain amounts paid to us within 90 days prior to the tenants bankruptcy filing could be required to be returned to the tenants
bankruptcy estate. In any event, it is highly unlikely that a bankrupt or insolvent tenant would pay in full amounts it owes us under a lease. In other circumstances, where a tenants financial condition has become impaired, we may agree to
partially or wholly terminate the lease in advance of the termination date in consideration for a lease termination fee that is likely less than the agreed rental amount. Without regard to the manner in which the lease termination occurs, we are
likely to incur additional costs in the form of tenant improvements and leasing commissions in our efforts to lease the space to a new tenant. In any of the foregoing circumstances, our results from operations, liquidity and financial condition
could be adversely affected, which could result in a decline in the value of our units.

New developments and acquisitions may fail to perform as
expected

We continue to develop and acquire 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 may increase, and there may be costs incurred for projects that are not completed. In deciding whether to acquire or develop a particular property, we make certain assumptions regarding the expected future
performance of that property. We may underestimate the costs necessary to bring an acquired property up to standards established for its intended market position, or may be unable to increase occupancy at a newly acquired property as quickly as
expected, or at all. If newly acquired properties or development projects are not completed in the timing or at the costs expected or do not perform as expected, our results of operations, liquidity and financial condition may be adversely affected,
which could result in a decline in the value of our units.

We may not be successful in identifying and consummating suitable acquisitions of office
properties meeting our criteria

Our ability to acquire office properties on favorable terms may be constrained by competition from
other investors with significant capital, including publicly traded REITs and institutional investors. Competition from these other potential acquirers may result in increased bidding, which may ultimately increase the price we must pay for a
property or may result in us being unable to acquire property at all.

##### Table of Contents

Failure to identify or consummate suitable acquisitions could adversely affect our ability to reinvest proceeds from property dispositions and thereby affect
our results of operations and reduce the price of our securities.

Illiquidity of real estate investments could significantly impede our ability to
respond to adverse changes in the performance of our properties

Because real estate investments are relatively illiquid, our ability to
promptly sell one or more properties in our portfolio in response to changing economic, financial and investment conditions is limited. The real estate market is affected by many forces, such as general economic conditions, availability of
financing, interest rates and other factors, including supply and demand, that are beyond our control. We cannot predict whether we will be able to sell any property for the price or on the terms set by us or whether any price or other terms offered
by a prospective purchaser would be acceptable to us. We also cannot predict the length of time needed to find a willing purchaser and to close the sale of a property.

We may be required to expend funds to correct defects or to make improvements before a property can be sold. We cannot assure you that we will have funds available to correct those defects or to make those
improvements.

CarrAmericas and our use of debt subjects us to various financing risks

Our liquidity and capital resources are dependent upon CarrAmerica and its other affiliates. We and CarrAmerica regularly borrow money to finance our
operations, particularly the acquisition and development of properties. We and CarrAmerica generally incur unsecured debt, although in some cases we will incur mortgage debt that is secured by one or more of our office buildings. In the future,
CarrAmericas and our financial condition could be materially and adversely affected by our use of debt financing, in part due to the following risks:



| |  |  | No Limitation on Debt Incurrence. Our organizational documents do not limit the amount of debt we can incur. Our leverage could have important consequences to our
unitholders, including affecting our ability to obtain additional financing in the future for working capital, capital expenditures, acquisitions, development or other general corporate purposes and making us more vulnerable to a downturn in
business or the economy generally. In addition, as a result of the financial and operating covenants described below, our leverage could reduce our flexibility in conducting our business and planning for, or reacting to, changes in our business and
in the real estate industry. Any such reduction in our ability to obtain additional financing or our flexibility to conduct our business could adversely affect our financial condition and results of operations. This could result in a decline in the
market value of our units.

| |  |  | Possible Inability to Meet Scheduled Debt Payments; Potential Foreclosure. If our properties do not perform as expected, the cash flow from our properties may not be
sufficient to make required principal and interest payments on our debt. 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 our assets in order to receive payment.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Inability to Refinance Debt. In most cases, 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 as a result of general economic downturns, if our credit rating is downgraded, if our properties do not
perform as expected, or otherwise, or extended or paid with proceeds of other capital transactions, such as property sales or new equity capital, our cash flow could be insufficient 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 which could adversely affect our results of operations, liquidity,
financial condition, ability to service debt and make distributions to our unitholders.

##### Table of Contents

| |  |  | Financial Covenants Could Adversely Affect CarrAmericas Financial Condition. CarrAmericas credit facilities and the indentures under which their senior
unsecured indebtedness are issued contain financial and operating covenants, including coverage ratios and other limitations on their ability to incur secured and unsecured indebtedness, sell all or substantially all of their assets and engage in
mergers, consolidations and certain acquisitions. Failure to meet their financial covenants could result from, among other things, changes in their results of operations or general economic changes. These covenants may restrict their ability to
engage in transactions that would otherwise be in their best interests. Failure to comply with any of the covenants under their unsecured credit facility or other debt instruments could result in a default under one or more of their debt
instruments. This could cause their lenders to accelerate the timing of payments and restrict their ability to make distributions to their security holders and would therefore have a material adverse effect on their business, operations, financial
condition or liquidity.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

CarrAmericas ability to draw on their unsecured credit facility or incur other unsecured debt
in the future could be restricted by certain covenants. During 2006, they may approach the limit of their unencumbered leverage ratio which restricts unsecured debt outstanding to no more than 60% of unencumbered assets. As of December 31,
2005, their unencumbered leverage ratio was 56.7%. Their unencumbered leverage ratio is most significantly impacted by the performance of their operating properties and net borrowings required to fund capital expenditures and pay their dividend as a
result of insufficient operating cash flow. Incurring additional unsecured debt to acquire additional unencumbered assets does not impact their unencumbered leverage ratio as significantly as incurring additional debt for other purposes. The
tangible fair market value of their unencumbered properties is calculated by applying capitalization rates stipulated in their line of credit of 8.5% - 9.0% to current operating income. Therefore, their unencumbered leverage ratio could increase if
the operating income of their unencumbered properties decreases. Additionally, the ratio will increase as they acquire properties which have operating income which is lower than 8.5% - 9.0% of the amount invested. If their unencumbered leverage
ratio increases and surpasses 60%, it could impact their business and operations, including their ability to incur additional unsecured debt, draw on their unsecured line of credit, which is their primary source of short term liquidity, pay
distributions to their security holders, acquire leveraged properties or invest in properties through joint ventures. CarrAmerica currently expects to work with their lenders to ensure that they remain in compliance with their covenants.



| |  |  | Variable Interest Rates Could Increase the Cost of Borrowing. As of December 31, 2005, approximately 28.2% of our total financing was subject to variable interest rates.
Because we have not hedged significantly against interest fluctuations, significant increases in interest rates could dramatically increase our costs of borrowing. Additionally, interest rates on certain types of our debt are based on the credit
rating of our debt by independent agencies, and would be substantially increased in the event that the credit ratings are downgraded.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Derivatives. We may use derivative financial instruments at times to limit market risk only for hedging purposes, not for speculation or trading purposes. Interest rate
protection agreements may be used to convert variable rate debt to a fixed rate basis, to convert fixed rate debt to a variable rate basis or to hedge anticipated financing transactions. However, these arrangements may expose us to additional risks.
Although our interest rate risk management policy establishes minimum credit ratings for counterparties, this does not eliminate the risk that counterparty may fail to honor its obligations. Developing an effective interest rate risk strategy is
complex and no strategy can completely insulate us from risks associated with interest rate fluctuations. In addition, hedging agreements may involve costs, such as transaction fees or breakage costs, if we terminate them. Any failure by us to
effectively manage our exposure to interest rate risk through hedging agreements or otherwise, and any costs associated with hedging arrangements, could adversely affect our results of operations or financial condition. This could cause the market
value of our units to decline.

| |  |  | CarrAmerica may need to borrow funds in order to pay distributions necessary to maintain their REIT status. In order to maintain their REIT status,
CarrAmerica may need to borrow funds on a short-term basis to meet the REIT distribution requirements, even if the then prevailing market conditions are not favorable for these borrowings. To qualify as a REIT, CarrAmerica generally

| | must distribute to their stockholders at least 90% of their REIT taxable income, excluding capital gains. In order to eliminate federal income tax, they must
distribute 100% of their net taxable income, including capital gains. CarrAmerica may need to incur debt to fund required distributions if their cash flows from operations are insufficient to make such distributions, as a result of differences in
timing between the actual receipt of income and the recognition of income for federal income tax purposes, or as a result of the effect of non-deductible capital expenditures, the creation of reserves or required debt or amortization payments. Any
such incurrence, particularly during unfavorable market conditions, could adversely affect their results of operations or financial condition. As a result, the market value of their securities could decline.

An earthquake or terrorist act could adversely affect our business

Over 35.9% of our property operating income in 2005 was generated by properties located in the states of California and Washington, which are high risk geographical areas for earthquakes. In addition, a significant
portion of our properties are located in the Washington, DC Metro Area and other major urban areas which have, in recent years, been high risk geographical areas for terrorism and threats of terrorism. Future earthquakes or acts of terrorism would
severely impact the demand for, and value of, our properties and could also directly impact the value of our properties through damage, destruction or loss and could thereafter materially impact the availability or cost of insurance to protect
against these events. A decrease in demand could make it difficult to review or re-lease our properties at lease rates equal to or above historical rates. To the extent that any future earthquakes or terrorist acts otherwise disrupt our
tenants businesses, it may impact their ability to make timely payments under their existing leases with us which would harm our operating results. Although we maintain earthquake and terrorism insurance for our properties and the resulting
business interruption, any earthquake or terrorist attack, whether or not insured, could have a material adverse effect on our results of operations, liquidity and financial condition, and result in a decline in the value of our units.

Uninsured losses or losses in excess of our insurance coverage could adversely affect our financial condition and our cash flows

Although we believe our properties are adequately covered by insurance, we cannot predict at this time if we will be able to obtain appropriate coverage
at a reasonable cost in the future. Our insurance costs have fluctuated significantly in recent years.

In response to the uncertainty in
the insurance market following the terrorist attacks of September 11, 2001, the Terrorism Risk Insurance Act of 2002 (TRIA) was enacted in November 2002, which established the Terrorism Risk Insurance Program to mandate that
insurance carriers offer insurance covering physical damage from terrorist incidents certified by the U.S. government as foreign terrorist acts. Under the Terrorism Risk Insurance Program, the federal government shares in the risk of loss associated
with certain future terrorist acts. The Terrorism Risk Insurance Program was scheduled to expire on December 31, 2005. However, on December 22, 2005, the Terrorism Risk Insurance Extension Act of 2005 (the Extension Act) was
enacted, which extended the duration of the Terrorism Risk Insurance Program until December 31, 2007, while expanding the private sector role and reducing the amount of coverage that the U.S. government is required to provide for insured losses
under the program.

While the underlying structure of TRIA was left intact, the Extension Act makes some adjustments, including increasing
the current insurer deductible from 15% of direct earned premiums to 17.5% for 2006, and to 20% of such premiums in 2007. For losses in excess of the deductible, the federal government still reimburses 90% of the insurers loss in 2007. The
federal share in the aggregate in any program year may not exceed $100 billion (the insurers will not be liable for any amount that exceeds this cap). Under the Extension Act, losses incurred as a result of an act of terrorism are required to exceed
$5.0 million before the program is triggered and compensation is paid under the program, but that amount increases to $50.0 million on April 1, 2006, and to $100.0 million in 2007. As a result, unless we obtain separate coverage for events that
do not meet that threshold (which coverage may not be required by the respective loan documents and may not otherwise be obtainable), such events would not be covered. In addition, the recently enacted legislation may subsequently result in
increased premiums charged by insurance carriers for terrorism insurance.

##### Table of Contents

In May 2004, CarrAmerica formed a wholly-owned captive insurance company which provides $490 million in
coverage against losses due solely to biological, chemical or radioactive contamination arising out of a certified terrorist act. In the event of a covered loss in 2006, we expect this captive insurance company to recover 90% of its losses, less
certain deductibles, from the United States government, but it has not reinsured its remaining exposure and may have insufficient capital to fully pay our claim. We or CarrAmerica will be required to fund the remaining 10% of a covered loss.

Should an uninsured loss or a loss in excess of insured limits occur, we could lose all or a portion of the capital we have invested in a
property, as well as the anticipated future revenue from the property. Nevertheless, we might remain obligated for any mortgage debt or other financial obligations related to the property. It is also possible that third-party insurance carriers will
not be able to maintain reinsurance sufficient to cover any losses that may be incurred.

In addition, if any of our properties were to
experience a catastrophic loss that was insured, there can be no assurance that such coverage will adequately compensate us for any loss, that our coverage would continue after a loss, or that a loss, even if covered, would not have a material
adverse effect on our business, financial condition or results of operations. It could still seriously disrupt our operations, delay revenue and result in large expenses to repair or rebuild the property. Also, due to inflation, changes in codes and
ordinances, environmental considerations and other factors, it may not be feasible to use insurance proceeds to replace a building after it has been damaged or destroyed.

Also, we have to renew our policies in most cases on an annual basis and negotiate acceptable terms for coverage, exposing us to the volatility of the insurance markets, including the possibility of rate increases.
Any material increase in insurance rates or decrease in available coverage in the future could adversely affect our results of operations and financial condition, which could cause a decline in the market value of our units.

Increases in taxes and regulatory compliance costs, including compliance with the Americans with Disabilities Act, may adversely affect our results of operations

We may not be able to pass all real estate tax increases through to our tenants. Therefore, any tax increases may adversely affect our
results of operations. Our properties also are subject to various federal, state and local regulatory requirements, such as state and local fire and life safety requirements. Some trade associations, such as the Building Owners and Managers
Association and the National Fire Protection Association (NFPA), publish standards that are adopted by government authorities. These include standards relating to life, safety and fire protection systems published by the NFPA. Failure to comply with
these requirements could result in the imposition of fines by governmental authorities or awards of damages to private litigants. In addition, we cannot provide any assurance that these requirements will not be changed or that new requirements will
not be imposed that would require significant unanticipated expenditures by us and could have an adverse effect on our results of operations.

Under the Americans with Disabilities Act of 1990 (ADA) and various state and local laws, all public accommodations and commercial facilities must meet certain federal requirements related to access and use by disabled persons. Compliance
with these requirements could involve removal of structural barriers from certain disabled persons entrances. Other federal, state and local laws may require modifications to or restrict further renovations of our properties with respect to
such means of access. Noncompliance with the ADA could result in the imposition of fines or an award of damages to private litigants and also could result in an order to correct any non-complying feature, which could result in substantial capital
expenditures. We have not conducted an audit or investigation of all of our properties to determine our compliance and we cannot predict the ultimate cost of compliance with the ADA or other legislation. If one or more of our properties is not in
compliance with the ADA or other legislation, then we would be required to incur additional costs to achieve compliance. If we incur substantial costs to comply with the ADA or other legislation, our financial condition, results of operation, cash
flow, per share trading price of our securities and our ability to satisfy our debt service obligations and to make distributions to our stockholders could be adversely affected.

Environmental compliance cost and liabilities associated with operating our properties may result in unanticipated
expenses and may affect our results of operations

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. In addition, the U.S. Environmental Protection Agency and the
U.S. Occupational Safety and Health Administration are increasingly involved in indoor air quality standards, especially with respect to asbestos, mold and medical waste. The clean up of any environmental contamination, including asbestos and mold,
can be costly. 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 or could prove so costly as to have a material adverse effect on our results
of operations, liquidity and financial condition, which could result in our inability to make distributions to our unitholders and result in a decline in the value of our units.

We do not have exclusive control over our joint venture investments

We have invested, and may invest
in the future, in projects or properties as a co-venturer or partner in the development of new properties. These investments involve risks not present in a wholly-owned project. Risks related to these investments could include:



| |  |  | Absence of control over the development, financing, leasing, management and other aspects of the project;
| | - |  | ---------------------------------------------------------------------------------------------------------



| |  |  | Possibility that our co-venturer or partner might:
| | - |  | --------------------------------------------------



| |  |  | become bankrupt;
| | - |  | ----------------



| |  |  | have interests or goals that are inconsistent with ours;
| | - |  | --------------------------------------------------------



| |  |  | take action contrary to our instructions, requests or interests (including those related to CarrAmericas qualification as a REIT for tax purposes); or
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | otherwise impede our objectives; and
| | - |  | ------------------------------------



| |  |  | Possibility that we, together with our partners, may be required to fund losses of the investee.
| | - |  | ------------------------------------------------------------------------------------------------

In addition, most of our joint venture agreements contain provisions, and may contain similar provisions in the future, that could require us to buy our partners interest or sell our interest or the property or
project at a time we do not deem favorable for financial or other reasons, including the availability of cash at such time and the impact of tax consequences resulting from any sale.

CarrAmericas status as a REIT

CarrAmerica believes that they qualify for taxation as a REIT
for federal income tax purposes, and they plan to operate so that they can continue to meet the requirements for taxation as a REIT. If they qualify as a REIT, they generally will not be subject to federal income tax on income that they distribute
currently to their shareholders. Many of the REIT requirements, however, are highly technical and complex. The determination that CarrAmerica is a REIT requires an analysis of various factual matters and circumstances that may not be totally within
their control. For example, to qualify as a REIT, at least 95% of their gross income must come from specific passive sources, like rent, that are itemized in the REIT tax laws. In determining that they have satisfied this requirement, they have
concluded that certain services, such as cafeteria services that were provided to tenants through an independent contractor at some of their properties under arrangements where they bore part or all of the expenses of such services, were considered
customary in the geographic area where such properties are located. There can be no assurance that the IRS or a court would agree with such conclusion or other positions CarrAmerica has taken interpreting the REIT requirements. They also are
required to distribute to their stockholders at least 90% of their REIT taxable income (excluding capital gains). The fact that they hold some of their assets through partnerships and their subsidiaries further complicates the application of the
REIT requirements. Even a technical or inadvertent mistake could jeopardize their 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 them to remain qualified as a REIT.

If CarrAmerica fails to qualify as a REIT for federal income tax purposes and do
not meet the requirements necessary to avail themselves of certain statutory relief provisions, they would be subject to federal income tax at regular corporate rates. Also, unless the IRS granted them relief under such statutory provisions, they
would remain disqualified as a REIT for four years following the year they first failed to



13

##### Table of Contents

qualify. If they failed to qualify as a REIT, they would have to pay significant income taxes. This likely would have a significant adverse effect on the
value of our units and our ability to make distributions to our unit holders.

Even if CarrAmerica qualifies as a REIT for federal income
tax purposes, they are required to pay certain federal, state and local taxes on their income and property. For example, if they have 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 CarrAmerica undertakes sales of assets that become inconsistent with their long term strategic or return objectives, they do not believe that those sales should be considered prohibited transactions, but
there can be no assurance that the IRS would not contend otherwise. They also will be subject to corporate-level tax upon the recognition of any built-in gain that exists with respect to assets acquired in tax-deferred, carry-over basis transactions
from non-REIT C corporations for 10 years following the acquisition. This rule will apply, for example, to the gain that existed on certain assets they acquired upon the liquidation of one of their taxable REIT subsidiaries on
December 31, 2003. In addition, any net taxable income earned directly by some of their affiliates, including Carr Real Estate Services Inc. and CarrAmerica Development Inc., is subject to federal and state corporate income tax. In this regard,
several provisions of the laws applicable to REITs and their subsidiaries ensure that a taxable REIT subsidiary will be subject to an appropriate level of federal income taxation. For example, a taxable REIT subsidiary is limited in its ability to
deduct interest payments made to an affiliated REIT. In addition, the REIT has to pay a 100% penalty tax on some payments that it receives or on some deductions taken by the taxable REIT subsidiaries 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. Several entities in which CarrAmerica owns interests, including Carr Real Estate Services Inc. and CarrAmerica Development
Inc., have elected to be taxable REIT subsidiaries. Finally, some state and local jurisdictions may tax some of their income even though as a REIT they are not subject to federal income tax on that income. To the extent that they and their
affiliates are required to pay federal, state and local taxes, they will have less cash available for distributions to their shareholders.

Insurance

Although we believe our properties are adequately covered by insurance, we cannot predict at this time if we will be able to obtain appropriate coverage at a reasonable cost in the future. Our insurance costs have
fluctuated significantly in recent years.

In response to the uncertainty in the insurance market following the terrorist attacks of
September 11, 2001, the Terrorism Risk Insurance Act of 2002 (TRIA), was enacted in November 2002, which established the Terrorism Risk Insurance Program to mandate that insurance carriers offer insurance covering physical damage
from terrorist incidents certified by the U.S. government as foreign terrorist acts. Under the Terrorism Risk Insurance Program, the federal government shares in the risk of loss associated with certain future terrorist acts. The Terrorism Risk
Insurance Program was scheduled to expire on December 31, 2005. However, on December 22, 2005, the Terrorism Risk Insurance Extension Act of 2005 (the Extension Act) was enacted, which extended the duration of the Terrorism
Risk Insurance Program until December 31, 2007, while expanding the private sector role and reducing the amount of coverage that the U.S. government is required to provide for the insured losses under the program.

While the underlying structure of TRIA was left intact, the Extension Act makes some adjustments, including increasing the current insurer deductible
from 15% of direct earned premiums to 17.5% for 2006, and to 20% of such premiums in 2007. For losses in excess of the deductible, the federal government still reimburses 90% of the insurers loss, but the amount of federal reimbursement
decreases to 85% of the insurers loss in 2007. The federal share in the aggregate in any program year may not exceed $100 billion (the insurers will not be liable for any amount that exceeds this cap). Under the Extension Act, losses incurred
as a result of an act of terrorism are required to exceed $5.0 million before the program is triggered and compensation is paid under the program, but that amount increases to $50.0 million on April 1, 2006, and to $100.0 million in 2007. As a
result, unless we obtain separate coverage for events that do not meet that threshold (which coverage may not be required by the respective loan documents and may not otherwise be obtainable), such events would not be covered. In addition, the
recently enacted legislation may subsequently result in increased premiums charged by insurance carriers for terrorism insurance.

In May
2004, CarrAmerica formed a wholly-owned captive insurance company which provides $490 million in coverage against losses due solely to biological, chemical or radioactive contamination arising out of a certified terrorist act. In the event of a
covered loss in 2006, we expect our captive insurance company to recover 90% of its losses, less certain deductibles, from the United States government, but it has not reinsured its remaining exposure and may have insufficient capital to fully pay
our claim. We or CarrAmerica would then be required to fund the remaining 10% of a covered loss.

In 2003, due to the rising cost of
California earthquake insurance, we reviewed our probable maximum loss (PML) and industry practice related to earthquake coverage for various factors. As a result of this review, we determined that it was possible to lower our earthquake
coverage from $200 million to $150 million. We believe this will be sufficient coverage but there can be no assurance that such coverage will adequately compensate us for any loss, that our coverage would continue after a loss, or that a loss, even
if covered, would not have a material adverse effect on our business, financial condition or results of operations.

Occupancy, Average
Rentals and Lease Expirations

As of December 31, 2005, 91.4% of the aggregate net rentable square footage in our 53 consolidated
operating office buildings was leased. The following table summarizes percent leased and average annualized rent per leased square foot (excluding storage space) for the past three years for the consolidated operating properties:

Mortgage Financing

As of December 31, 2005, one of our consolidated operating properties was subject to fixed rate mortgage indebtedness ($13.8 million.) The following
table details information regarding the existing mortgage indebtedness for the consolidated operating property as of December 31, 2005.



|            |  |              |   |  |                          |        |              |         |                            |   |                                        |  |   |

During the fourth quarter of 2005, we sold our 2600 West Olive property. We used the proceeds from
the disposition to repay the related $17.9 million of fixed rate debt and the $1.2 million of prepayment penalties, which were incurred as a result of the prepayment. The prepayment penalties were included in discontinued operations since we were
required to repay the mortgage upon sale of the related property. We repaid an aggregate of $40.3 million of third-party fixed rate debt in 2004, of which $29.8 million was extinguished early and incurred prepayment penalties of $0.8 million which
were included in interest expense. In connection with the 2004 prepayments, we borrowed $19.5 million under a variable rate note from CarrAmerica.

Item 3. LEGAL PROCEEDINGS

We are
party to a variety of legal proceedings arising in the ordinary course of business. All of these matters, taken together, are not expected to have a material adverse impact on us. Based on currently available facts, we believe that the disposition
of matters that are pending or asserted will not have a material adverse effect on our consolidated financial position, results of operations or liquidity.

Item 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

None.

PART II

Item 5. MARKET FOR REGISTRANTS
COMMON EQUITY AND RELATED STOCKHOLDER MATTERS

There is no established public trading market for our Units. As of December 31,
2005, there were 24 holders of Units on record. As of December 31, 2005, there were no options or warrants to purchase Units outstanding. In addition, as of December 31, 2005, there were no Units that were being, or have been, proposed to
be publicly offered by us.

Each Unit held by partners, other than GP Holdings or LP Holdings, is (subject to holding period limitations)
redeemable for cash equal to the value of a share of CarrAmerica common stock or, at the option of GP Holdings, CarrAmerica common stock on a one-for-one basis. For the high and low trading prices of CarrAmericas common stock for the last two
years, see Item 5  Market for Registrants Common Equity and Related Stockholder Matters in the 2005 CarrAmerica 10-K, which information is hereby incorporated by reference.

Under our partnership agreement, to the extent that there is available cash, each Class A Unit, Class D Unit, and Class E Unit is entitled to
receive a distribution equal to the amount of dividend per common share that is paid to CarrAmericas shareholders. Once all of the holders of these units have received their distribution, all additional available cash may be distributed to the
holders of Class B Units. We have made regular quarterly distributions of $0.50 per Class A, D and E Unit throughout 2005 and 2004. The distributions are appropriately prorated to reflect ownership of Units for less than the full period to
which the distribution relates. Our ability to make distributions depends on a number of factors, including net cash provided by operating activities, capital commitments and debt repayment schedules. Holders of Units are entitled to receive
distributions when, as and if declared by the Board of Directors of CarrAmerica, out of any funds legally available for that purpose.

Cash
flows from operations are an important factor in our ability to sustain our quarterly distributions to our partners at the current rate $0.50 per unit per quarter. Cash flows from operations decreased from $48.7 million in 2004 to $34.2 million in
2005. We expect our cash flow from operations to be lower in 2006 than 2005 and tenant improvements are expected to remain at elevated levels as a result of factors mentioned in the introduction to Item 7 (Managements Discussion and
Analysis of Financial Condition and Results of Operations) to CarrAmericas Annual Report of Form 10-K for the year ended December 31, 2005, including but not limited to, declining rental rates in certain of our markets with expiring
leases, rent abatement features in many of the new leases at our properties and, most significantly, their estimated tenant-related and other capital expenditures associated with new leases. We anticipate that these factors will negatively impact
our cash flows from operations and our ability to cover our current distribution level using cash flows from operations. We currently expect to maintain our distribution rate of $0.50 per unit per quarter in 2006. As a result, we may need to borrow
under our line of credit or sell assets in order to maintain our distribution rate. There can be no assurance that circumstances may not change and as a result of poorer than expected operating results or the inability to obtain financing on
favorable terms, or at all, that we will not later reduce our distributions below the current rate.

Item 7. MANAGEMENTS DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The discussion that follows is based primarily on our consolidated financial statements
as of December 31, 2005 and 2004, and for the years ended December 31, 2005, 2004 and 2003 and should be read along with the consolidated financial statements and related notes. The ability to compare one period to another may be
significantly affected by acquisitions completed, development properties placed in service and dispositions made during those years. The number of operating office buildings that we owned and were consolidated in the financial statements was 53, 53
and 55 as of December 31, 2005, 2004 and 2003, respectively.

The contraction of office workforces through 2002, reduced demand for
office space and overall vacancy rates for office properties increased in all of our markets and our operations were adversely impacted. In 2003, vacancy rates appeared to peak in many of our markets and some positive net absorption of space started
to occur. In 2004, the positive trend of reduced vacancy rates and positive net absorption continued in most of our markets. As a result of improved job growth, leasing activity increased significantly, and we believe that market rental rates
stabilized in all of our markets. In 2005, rental economics improved in most of our markets and we expect this to continue in 2006. The occupancy in our portfolio of operating properties was 91.4% at December 31, 2005 and 87.8% at both
December 31, 2004 and 2003. Due to the improving market conditions described above and the elimination of most of our poor credit quality tenants through lease defaults and terminations, our average occupancy in all markets stabilized in 2004
and in 2005 began to improve. If demand continues to improve in 2006, we expect that our overall portfolio average occupancy may improve further.

##### Table of Contents

While we believe market rental rates have stabilized and are improving in many of our markets, rental
rates on in-place leases in certain markets remain significantly above current market rental rates. We estimate that market rental rates on leased space expiring in 2006 will be, on average, approximately 10%-12% lower than straight-lined rents on
expiring leases. Leases representing 4.8% (approximately 198,000 square feet) of the net rentable square feet at our properties will expire before December 31, 2006.

We have decided, based on current returns and other market factors, to market for sale the majority of our wholly-owned properties in Chicago and Denver, and we have begun these efforts in the first quarter of 2006.
We intend to reinvest the proceeds from the sale of Chicago and Denver in our other markets where we believe we will recognize a greater return on our invested capital. There can be no assurance that these dispositions will be consummated on
favorable terms, if at all. There can be no assurance any of these sales will be consummated. We plan to use any proceeds resulting from the sale of any property for the acquisition and development of other properties or for general corporate
purposes, including ongoing tenant improvements and the funding of cash flow shortfalls in order to maintain and pay dividends on our common and preferred stock and distributions to third party unitholders in certain of our subsidiaries. The
properties did not meet our criteria to be classified as held for sale for financial reporting purposes as of December 31, 2005. A summary of the net book value of the assets and the operating results of our Chicago and Denver properties as of
and for the twelve months ended December 31, 2005 is as follows:

We expect our cash flows from operations will continue at reduced levels in 2006 and tenant improvements and lease incentives are expected to remain at
elevated levels as a result of factors mentioned in the introduction to Item 7 (Managements Discussion and Analysis of Financial Condition and Results of Operations) of CarrAmericas Annual Report of Form 10-K for the year ended
December 31, 2005, including but not limited to declining rental rates in certain of our markets with expiring leases, particularly in Northern California, rent abatement features in many of the new leases at our properties and, most
significantly, our estimated tenant-related and other capital expenditures associated with new leases. We anticipate that these factors will negatively impact our cash flows from operations and our ability to cover our current distribution level
using cash flow from operations. We currently expect to maintain our distribution rate of $0.50 per unit per quarter in 2006. As a result we may need to borrow under our line of credit or sell assets in order to maintain our distribution rate. There
can be no assurance that circumstances may not change and as a result of poorer than expected operating results or the inability to obtain financing on favorable terms, or at all, that we will not later reduce our distributions below the current
rate.

Critical Accounting Policies and Estimates

Critical accounting policies and estimates are those that are both important to the presentation of our financial condition and results of operations and require managements most difficult, complex or subjective
judgments. Our critical accounting policies and estimates relate to revenue recognition, estimating the depreciable lives of assets, evaluating the impairment of long-lived assets and investments, allocating the purchase cost of acquired properties,
and evaluating the collectibility of accounts receivable.

We commence revenue recognition on our leases based on a number of factors. In
most cases, revenue recognition under a lease begins when the lessee takes possession of or controls the physical use of the leased asset. Generally, this occurs on the lease commencement date. In determining what constitutes the leased asset, we
evaluate whether we or the lessee is the owner, for accounting purposes, of the tenant

improvements. If we are the owner, for accounting purposes, of the tenant improvements, then the leased asset is the finished space and revenue recognition
begins when the lessee takes possession of the finished space, typically when the improvements are substantially complete. If we conclude we are not the owner, for accounting purposes, of the tenant improvements (the lessee is the owner), then the
leased asset is the unimproved space and any tenant improvement allowances funded under the lease are treated as lease incentives which reduces revenue recognized over the term of the lease. In these circumstances, we begin revenue recognition when
the lessee takes possession of the unimproved space for the lessee to construct improvements. The determination of who is the owner, for accounting purposes, of the tenant improvements determines the nature of the leased asset and when revenue
recognition under a lease begins. We consider a number of different factors to evaluate whether we or the lessee is the owner of the tenant improvements for accounting purposes. These factors include:



| |  |  | whether the lease stipulates how and on what a tenant improvement allowance may be spent;
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | whether the tenant or landlord retains legal title to the improvements;
| | - |  | -----------------------------------------------------------------------



| |  |  | the uniqueness of the improvements;
| | - |  | -----------------------------------



| |  |  | the expected economic life of the tenant improvements relative to the length of the lease; and
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | who constructs or directs the construction of the improvements.
| | - |  | ---------------------------------------------------------------

The
determination of who owns the tenant improvements, for accounting purposes, is subject to significant judgment. In making that determination we consider all of the above factors. No one factor, however necessarily determines our conclusion.

If a lease provides for rent based on the resolution of contingencies, such as meeting a level of sales by the tenant, we defer rent
associated with rental contingencies until the resolution of the contingency.

Depreciation of rental properties is computed on a
straight-line basis over the estimated useful lives of the assets. The estimated lives of our assets by class are as follows:



|                                  |  |                                                                
|--------------------------------- |  | ---------------------------------------------------------------
|Base building                     |  | 20-40 years                                                    
|Building components               |  | 7 to 20 years                                                  
|Tenant improvements               |  | Lesser of the terms of the leases or useful lives of the assets
|Furniture, fixtures and equipment |  | 5 to 15 years                                                  

We make subjective assessments as to the useful lives of our assets. These assessments have a direct impact on our
net income. Should we lengthen the expected useful life of an asset, it would be depreciated over a longer period, resulting in less depreciation expense and higher annual net income. Should we shorten the expected useful life of an asset, it would
be depreciated over a shorter period, resulting in more depreciation expense and lower annual net income.

We assess the carrying values of
our assets on a regular basis. If events or changes in circumstances indicate that the carrying value of a rental property to be held and used or land held for development may be impaired, we perform a recoverability analysis based on estimated
undiscounted cash flows to be generated from the property in the future. If the analysis indicates that the carrying value is not recoverable from future cash flows, the property and related assets, such as tenant improvements, lease commissions and
in-place lease intangibles, are written down to estimated fair value and an impairment loss is recognized. If we decide to sell rental properties or land holdings, we evaluate the recoverability of the carrying amounts of the assets. If the
evaluation indicates that the carrying value is not recoverable from estimated net sales proceeds, the property and related assets are written down to estimated fair value less costs to sell and an impairment loss is recognized. Our estimates of
cash flows and fair values of the properties are based on current market conditions and consider matters such as rental rates and occupancies for comparable properties, recent sales data for comparable properties and, where applicable, contracts or
the results of negotiations with purchasers or prospective purchasers. Changes in estimated future cash flows due to changes in our plans or views of market and economic conditions could result in recognition of additional impairment losses which,
under applicable accounting guidance, could be substantial.

We allocate the purchase cost of acquired properties to the related physical assets and in-place leases
based on their fair values. The fair values of acquired office buildings are determined on an if-vacant basis considering a variety of factors, including the physical condition and quality of the buildings, estimated rental and
absorption rates, estimated future cash flows and valuation assumptions consistent with current market conditions. The if-vacant fair value is allocated to land, where applicable, buildings, tenant improvements and equipment based on
property tax assessments and other relevant information obtained in connection with the acquisition of the property.

The fair value of
in-place leases includes the effect of leases with above or below market rents, customer relationship value, where applicable, and the cost of acquiring existing tenants at the date of acquisition. Above market and below market in-place lease values
are determined on a lease by lease basis based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between (a) the contractual amounts to be paid under the lease and
(b) our estimate of the fair market lease rate for the corresponding space over the remaining non-cancellable terms of the related leases. The capitalized below market lease values are amortized as an increase to rental revenue over the initial
term and any below market renewal periods of the related leases. Capitalized above market lease values are amortized as a decrease to rental revenue over the initial term of the related leases. Customer relationship values are determined based on
our evaluation of the specific characteristics of each tenants lease and our overall relationship with the tenant. Characteristics we consider include the nature and extent of our existing business relationships with the tenant, prospects for
developing new business with the tenant, the tenants credit quality and expectations of lease renewals. The value of customer relationship intangibles is amortized to expense over the lesser of the initial lease term and any expected renewal
periods or the remaining useful life of the building. We determine the fair value of the cost of acquiring existing tenants by estimating the lease commissions avoided by having in-place tenants and avoided lost operating income for the estimated
period required to lease the space occupied by existing tenants at the acquisition date. The cost of acquiring existing tenants is amortized to expense over the initial term of the respective leases. Should a tenant terminate its lease early, the
unamortized portion of the in-place lease value is charged to expense. Changes in the assumptions used in the allocation of the purchase cost among the acquired assets would affect the timing of recognition of the related revenue and expenses.

Our allowance for doubtful accounts receivable is established based on analysis of the risk of loss on specific accounts. The analysis
places particular emphasis on past-due accounts and considers information such as the nature and age of the receivable, the payment history of the tenant or other debtor, the amount of security we hold, the financial condition of the tenant and our
assessment of its ability to meet its lease obligations, the basis for any disputes and the status of related negotiations. Our estimate of the required allowance, which is reviewed on a quarterly basis, is subject to revision as these factors
change and is sensitive to the effects of economic and market conditions on our tenants, particularly in our largest markets. Bad debt expense was $0.2 million, $0.6 million, and $0.7 million for 2005, 2004, and 2003, respectively. The decreases in
bad debts expense from 2003 to 2004 and 2005 were due primarily to the reduction of delinquent tenants as marginal tenants leases were terminated or sublet.

During 2005, we acquired four operating properties (North Creek Corporate Center, Park Place
Office Tower, West Willows Technology Center and Chancellor Park). These acquisitions affect the comparisons of our operating results. Operating results of the properties acquired in 2005 are summarized as follows:



|                              |  |   |

|                              |  |   |      

During 2004 and 2003, we did not acquire any real estate properties.

Operating revenues increased $7.6 million (10.0%) in 2005 as compared to 2004 and decreased $4.9 million (6.1%) in 2004 as compared to 2003.
Revenues in 2005 increased primarily as a result of the 2005 acquisitions ($5.5 million) and improving occupancy partially offset by lower rental rates. Revenues in 2004 decreased from 2003 primarily due to decreases in minimum base rents ($1.5
million), recoveries from tenants ($2.7 million), and other tenant charges ($0.5 million). These decreases were due primarily to lower occupancy rates during the first three quarters of 2004 and lower rental rates for new and renewing tenants during
2004.

Property operating expenses increased $2.7 million (9.0%) in 2005 as compared to 2004 and $0.1 million (0.3%) in 2004 as
compared to 2003. Property operating expenses increased in 2005 due primarily to the 2005 acquisitions ($1.5 million). The increase in 2004 from 2003 is primarily due to higher operating expenses partially offset by lower insurance costs and bad
debt expense.

General and administrative expenses increased $0.9 million (10.1%) in 2005 as compared to 2004 and decreased $0.3
million (3.3%) during 2004 as compared to 2003. The increase in general and administrative expenses from 2005 to 2004 was due to higher allocations of expense from CarrAmerica as a result of our acquisitions. The acquisitions caused changes to
the allocation base computational components. The decrease in 2004 from 2003 was due primarily to decreased costs allocated from CarrAmerica ($0.3 million).

Depreciation and amortization expense increased $3.7 million (14.6%) in 2005 as compared to 2004 and $0.4 million (1.6%) in 2004 as compared to 2003. The increase in 2005 was primarily due to acquisitions
($3.3 million). The increase in 2004 was due primarily to increased depreciation of tenant improvements ($0.2 million).

Interest expense decreased $1.9 million (22.9%) in 2005 as compared to 2004 and $0.3 million
(3.5%) in 2004 as compared to 2003. The decrease in interest expense during 2005 was a result of the decrease in the weighted average debt outstanding for the year ended December 31, 2005 from the year ended December 31, 2004. The
decrease in 2004 was due primarily to the effects of a decrease in outstanding debt ($0.9 million) partially offset by increases in rates ($0.6 million). During 2004 our mortgages and notes payable balance decreased $20.8 million as a result of
repayments of mortgages payable ($39.6 million), partially offset by increased borrowings from affiliates ($18.8 million).

Other income
decreased $1.5 million (55.6%) in 2005 as compared to 2004 and $0.4 million (12.9%) in 2004 as compared to 2003. The decrease from 2004 to 2005 was a result of a decrease in equity in earnings of unconsolidated entities ($1.3 million)
primarily due to lower earnings from Carr Office Park, LLC. In addition, during 2004, Carr Office Park, LLC received a large settlement payment from a tenant to terminate a development rights agreement. The decrease in other income from 2003 to 2004
was due primarily to a decrease in interest income ($0.4 million).

During 2005, we recorded an accrual for $748,000 for a tax contingency.
No accruals were recorded in 2004 or 2003.

We dispose of assets (sometimes using tax-deferred exchanges) that are inconsistent with our
long-term strategic or return objectives or where market conditions for sale are favorable. The proceeds from the sales are redeployed into other properties or to support other needs.

During 2005, we disposed of our Phoenix portfolio, 2600 West Olive, Two Mission, and the Quorum properties in Dallas, Texas. Prior to the sale of the
Phoenix and Quorum buildings, we recognized impairment losses of $6.7 million. We recognized gains of approximately $25,000 and $63,000, respectively, on these transactions, which along with the properties results of operations, are classified
as discontinued operations as we have no continuing involvement with the properties after the sales. In addition, we completed the sale of the Phoenix portfolio and sold 2600 West Olive and Two Mission during the fourth quarter of 2005. We
recognized gains of $16.6 million, which along with the properties results of operations, are classified as discontinued operations as we have no continuing involvement with the properties after the sales. A joint venture in which we owned a
21.2% interest, sold an office building in June 2005. We recognized a gain of $0.5 million on the sale and received cash proceeds of $3.5 million.

We disposed of our Tower of the Hills property in the first quarter of 2004, resulting in proceeds of approximately $10.5 million and recognized a gain of $0.1 million. We previously recognized an impairment loss of $3.0 million on this
property in the fourth quarter of 2003. We have no continuing involvement with the Tower of the Hills property after the sale and accordingly, the gain on this sale, the impairment loss and the operating results of this property are classified as
discontinued operations.

During 2003, we did not dispose of any operating properties, although we reduced a previously recognized gain
$0.4 million for additional costs related to a sold property.

Discontinued operations increased $6.4 million in 2005 as compared to 2004
and $0.4 million in 2004 as compared to 2003.

Operations provided net cash of $34.2 million in 2005 as compared to $48.7 million in 2004 and
$49.1 million in 2003. The changes in cash flow from operating activities were primarily the result of fluctuations in timing of receipt of outstanding receivables and payment of accounts payable and the factors discussed above in the analysis of
operating results.

Our investing activities used net cash of $27.8 million in 2005, provided net cash of $0.2 million in 2004 and used net
cash of $14.0 million in 2003. The change in cash flows from investing activities in 2005 compared to 2004 was due primarily to the net effect of an increase in acquisition and capital expenditures activity during 2005 ($178.3 million) partially
offset by an increase in dispositions during 2005 ($151.3 million). The change in cash flows from investing activities in 2004 as compared to 2003 was due primarily to increased proceeds from dispositions of properties ($10.5 million) and reduced
costs of acquisition and development of rental property ($3.3 million).

Financing activities used net cash of $6.5 million, $48.9 million
and $36.7 million in 2005, 2004 and 2003, respectively. The decrease in net cash used in financing activities in 2005 compared to 2004 was due to a decrease in repayments of mortgage and notes payable ($21.8 million), increased net borrowings from
affiliates ($12.0 million) and decreased distributions to unit holders ($8.7 million). The increase in net cash used in financing activities in 2004 as compared to 2003 was due primarily due to increased distributions to unit holders ($8.2 million)
due primarily to the distributions of available cash to Class B Unitholders (affiliates of CarrAmerica) pursuant to our partnership agreement and net repayments on debt and amounts due to affiliates ($4.1 million).

Liquidity and Capital Resources

General

Our liquidity and capital resources are dependent upon CarrAmerica and its other affiliates. CarrAmericas primary sources of
capital are their real estate operations and their unsecured credit facility. As of December 31, 2005, CarrAmerica had approximately $15.8 million in cash and cash equivalents, $4.5 million of restricted cash and $369.1 million available for
borrowing under their unsecured credit

facility. They derive substantially all of their revenue from tenants under leases at their properties. Their operating cash flow therefore depends
materially on the rents that they are able to charge to their tenants, and the ability of those tenants to make their rental payments.

Our
primary uses of cash are to fund distributions to unitholders, to fund capital investment in our existing portfolio of operating assets and to fund new acquisitions and our development activities. We regularly require capital to invest in our
existing portfolio of operating assets in connection with large-scale renovations, routine capital improvements, deferred maintenance on properties we have recently acquired, and our leasing activities, including funding tenant improvements,
allowances and leasing commissions. The amounts of the leasing-related expenditures can vary significantly depending on negotiations with tenants and the willingness of tenants to pay higher base rents over the life of the leases.

During 2006, we expect that we will have significant capital requirements, including the following items. There can be no assurance that our capital
requirements will not be materially higher or lower than these expectations.



| |  |  | Approximately $1.8-2.0 million in distributions to Unitholders (other than Class B Unitholders);
| | - |  | ------------------------------------------------------------------------------------------------



| |  |  | Approximately $15-$19 million to invest in our existing portfolio of operating assets, including approximately $11-$14 million to fund tenant-related capital requirements;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We expect to meet our capital requirements using cash generated by our real estate operations, by borrowings from
CarrAmericas unsecured credit facility, and from proceeds from the sale of properties.

We believe that we will generate sufficient
cash flow from operations and the possible disposition of assets and have access to the capital resources necessary to expand and develop our business, to fund our operating and administrative expenses, to continue to meet our debt service
obligations, to pay distributions to Unitholders, to acquire additional properties and land and to pay for construction in progress. However, as a result of general economic downturns, if CarrAmericas cash flow from operations are adversely
affected in 2006 due to declining rental rates in certain of their markets with expiring leases, rent abatement features in many of the new leases at their properties and most significantly, their estimated tenant-related and other capital
expenditures associated with new leases, we may not generate sufficient cash flow from operations or otherwise have access to capital on favorable terms, or at all. If we cannot raise the expected funds from the sale of properties and/or if we are
unable to obtain capital from other sources, we may not be able to pay the distributions at their current level, make required principal and interest payments, continue our development activities, make strategic acquisitions or make necessary
routine capital improvements with respect to our existing portfolio of operating assets. Any of these events could have a material adverse effect on our liquidity, financial condition, results of operations and the value of our units. In addition,
if a property is mortgaged to secure payment of indebtedness and we are unable to meet mortgage payments, the holder of the mortgage could foreclose on the property, resulting in loss of income and asset value. An unsecured lender could also attempt
to foreclose on some of our assets in order to receive payment. In most cases, very little of the principal amount that we borrow is repaid prior to the maturity of the loan. We may refinance that debt when it matures, or 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 may be insufficient 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.

Under our partnership agreement to the extent that there is available cash, each Class A Unit, Class D Unit, and Class E Unit is entitled to receive
a distribution equal to the amount of dividend per common share that is paid to CarrAmericas shareholders. Once all of the holders of these units have received their distribution, all additional available cash may be distributed to the holders
of Class B Units. Cash flows from operations are an important factor in our ability to sustain our quarterly distributions to our partners at the current rate of $0.50 per unit per quarter. Cash flows from operations decreased from $48.7 million in
2004 to $34.2 million in 2005. We expect our cash flow from operations to be lower in 2006 than 2005 and tenant improvements are expected to remain at elevated levels as a result of factors mentioned in the introduction to Item 7
(Managements Discussion and Analysis of Financial Condition and Results of Operations) of CarrAmericas Annual Report on Form 10-K for the year ended December 31,

2005, including but not limited to, continued declines in rental rates compared to the rates on expiring leases. We expect that these factors will negatively
impact our cash flows from operations. We currently expect to maintain our distribution rate of $0.50 per unit per quarter in 2006. We expect that operating cash flow will be sufficient to maintain these distributions. In the event available cash is
insufficient to pay distributions at the current level we may be unable to make distributions to our Class B Unitholders.

Debt Financing

CarrAmerica generally uses unsecured, corporate-level debt, including senior unsecured notes and their unsecured credit facility, to
meet their borrowing needs. As a component of this financing strategy, they continue to unencumber their assets where possible by repaying existing mortgage debt with unsecured debt.

CarrAmerica generally uses fixed rate debt instruments in order to match the returns from their real estate assets. CarrAmerica also utilizes variable
rate debt for short-term financing purposes or to protect against the risk, at certain times, that fixed rates may overstate their long-term costs of borrowing if assumed inflation or growth in the economy implicit in higher fixed interest rates do
not materialize. At times, their mix of variable and fixed rate debt may not suit their needs. At those times, they use derivative financial instruments including interest rate swaps and caps, forward interest rate options or interest rate options
in order to assist in managing their debt mix. CarrAmerica will either hedge their variable rate debt to give it a fixed interest rate or hedge fixed rate debt to give it a variable interest rate.

CarrAmerica has three investment grade ratings. As of December 31, 2005, Fitch Rating Services and Standard & Poors have each assigned
their BBB rating to CarrAmericas prospective senior unsecured debt offerings and their BBB- rating to CarrAmericas prospective cumulative preferred stock offerings. Moodys Investor Service has assigned its Baa2 rating with a stable
outlook to CarrAmericas prospective senior unsecured debt offerings and its Baa3 rating to their prospective cumulative preferred stock offerings. A downgrade in rating by any one of these rating agencies could result from, among other things,
a change in their financial position or a downturn in general economic conditions. Any such downgrade could adversely affect their ability to obtain future financing or could increase the interest rates on their existing variable rate debt. However,
as of December 31, 2005, we have no debt instruments under which the principal maturity would be accelerated upon a downward change in our debt rating.

CarrAmericas primary external source of liquidity is their credit facility. On June 30, 2004, they entered into a new $500.0 million, three year unsecured revolving credit facility with JPMorgan Chase Bank
as administrative agent for a syndicate of banks. The facility replaced and was used to repay all amounts outstanding under their previous unsecured senior credit facility. They may increase the facility to $700.0 million by their request at any
time within 24 months of the closing, provided the funding commitments are increased accordingly. The facility can be extended one year at their option. The facility carries an interest rate of 65 basis points over 30-day LIBOR, or 5.04% as of
December 31, 2005. As of December 31, 2005, $120.0 million was drawn on the credit facility, $10.9 million in letters of credit were outstanding, and $369.1 million was available for borrowing.

CarrAmericas unsecured credit facility contains financial and other covenants with which it must comply. Some of these covenants include:



| |  |  | A minimum ratio of annual EBITDA (earnings before interest, taxes, depreciation and amortization) to interest expense of at least 2 to 1;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------



| |  |  | A minimum ratio of annual EBITDA to fixed charges of at least 1.5 to 1;
| | - |  | -----------------------------------------------------------------------



| |  |  | A maximum ratio of aggregate unsecured debt to tangible fair market value of its unencumbered assets of 60%;
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | A maximum ratio of total secured debt to tangible fair market value of 30%;
| | - |  | ---------------------------------------------------------------------------



| |  |  | A maximum ratio of total debt to tangible fair market value of CarrAmericas assets of 60%; and
| | - |  | -----------------------------------------------------------------------------------------------



| |  |  | Restrictions on its ability to make dividend distributions in excess of 90% of funds from operations or the minimum amount necessary to enable CarrAmerica to maintain its status as
a REIT.

##### Table of Contents

As of December 31, 2005, CarrAmerica is in compliance with all debt covenants related to its
unsecured line of credit, however, their ability to draw on the unsecured facility or incur other significant debt in the future could be restricted by the covenants. During 2006, CarrAmerica may approach the limit of their unencumbered leverage
ratio which restricts unsecured debt outstanding to no more than 60% of unencumbered assets. As of December 31, 2005, CarrAmericas unencumbered leverage ratio was 56.7%. Their unencumbered leverage ratio is most significantly impacted by
the performance of their operating properties and net borrowings required to fund capital expenditures and pay their dividend as a result of insufficient operating cash flow. Incurring additional unsecured debt to acquire additional unencumbered
assets does not impact their unencumbered leverage ratio as significantly as incurring additional debt for other purposes. The tangible fair market value of CarrAmericas unencumbered properties is calculated by applying capitalization rates
stipulated in their line of credit of 8.5% - 9.0% to current operating income. Therefore, their unencumbered leverage ratio could increase if the operating income of their unencumbered properties decreases. Additionally, the ratio will increase as
CarrAmerica acquires properties which have operating income which is lower than 8.5% - 9.0% of the amount invested. If their unencumbered leverage ratio increases and surpasses 60%, it could impact their business and operations, including their
ability to incur additional unsecured debt, draw on their unsecured line of credit, which is their primary source of short term liquidity, acquire leveraged properties or invest in properties through joint ventures. CarrAmerica currently expects to
work with their lenders to ensure that they remain in compliance with their covenants.

Our total debt at December 31, 2005 is
summarized as follows:



|                                        |  |   |       
|--------------------------------------- |  | - | ------

|Fixed rate notes payable to affiliate   |  |   | 54,890
|Variable rate note payable to affiliate |  |   | 27,000
|                                        |  |   |       
|                                        |  | $ | 95,713
|                                        |  |   |       

Our fixed rate debt bore an effective weighted average interest rate of 7.44% at December 31,
2005 and had a weighted average maturity of 5.5 years. The mortgage debts interest rate was 7.13% at December 31, 2005 and matures in 3.4 years. Our variable rate note payable to affiliate at December 31, 2005 bore an interest rate
of 100 basis points over 30-day LIBOR or 5.4% as of December 31, 2005. We repaid $17.9 million of fixed rate debt with a portion of the sale proceeds from our 2600 West Olive property. Related to the extinguishment, we incurred $1.2 million of
prepayment penalties, which are included in discontinued operations. During 2004, we repaid $40.3 million of fixed rate debt, of which $29.8 million was extinguished early. In connection with these extinguishments, we borrowed $19.5 million under a
variable rate note from CarrAmerica and incurred prepayment penalties of $0.8 million, which are included in interest expense in 2004.

We
have four loans with CarrAmerica. The first is a $30.0 million loan (balance at December 31, 2005 of $24.9 million) that bears interest at 8.5%, requires monthly principal and interest payments of $242,000 and matures on May 31, 2011. The
second is a $12.0 million loan that bears interest at 8.5% and requires monthly interest only payments of $85,000 and matures on March 27, 2007. The third note in the principal amount of $27.0 million requires interest only payments equal to
100 basis points over 30-day LIBOR (5.4% as of December 31, 2005) and matures on December 31, 2017. The fourth is a $18.0 million loan that bears interest at 5.5% and requires monthly interest only payments of $82,500 and matures on
November 30, 2015. Total interest paid to CarrAmerica under these loans was $4.5 million in 2005 and $3.3 million in 2004 and 2003.

As of December 31, 2005, we owed our affiliates and CarrAmerica Realty Corporation and its affiliates, $5.5 million compared to $8.9 million as of December 31, 2004. These amounts are subject to interest of 12% computed monthly.
The interest expense associated with amounts due to our affiliates was $0.9 million in 2005 and $0.8 million in 2004. Acquisitions completed during 2005 totaling $167.2 million have been funded primarily by disposition of properties and loans from
CarrAmerica. We expect to repay amounts due to our affiliates through proceeds from dispositions or operations.

##### Table of Contents

During the third quarter of 2004, we transferred a note receivable of $7.4 million from CarrAmerica
Development, Inc. to CarrAmerica as payment for amounts due to CarrAmerica. This transfer resulted in a decrease in notes receivable and due to affiliates. Additionally, notes receivable and due to affiliates decreased as a result of repayments
consistent with cash flows generated during 2004.

During 2004 we made distributions of $10.6 million, including distributions of $8.4
million to CarrAmerica. Under our partnership agreement, to the extent that there is available cash, each Class A Unit, Class D Unit, and Class E Unit is entitled to receive a distribution equal to the amount of dividend per CarrAmerica share
that is paid to its stockholders. Pursuant to the partnership agreement, subsequent to distributions to Class A, Class D and Class E Unitholders, we determined that cash was available to distribute to Class B Unitholders. CarrAmerica is the
only holder of Class B Units. No distributions were made to CarrAmerica during 2005.

Capital Commitments

We regularly incur expenditures in connection with the re-leasing of office space, principally in the form of tenant improvements and leasing commissions.
The amounts of these expenditures can vary significantly, depending on negotiations with tenants and the willingness of tenants to pay higher base rents over the life of the leases. We expect to pay for these capital expenditures out of cash from
operations or, to the extent necessary, borrowings from CarrAmerica. We believe that these expenditures are generally recouped in the form of continuing lease payments.

Below is a summary of certain obligations that will require significant capital:



|                            |  |                        |        |                 |   |          |  |          |        |              |   |        |  |   |

We have various standing or renewable contracts with vendors. These contracts are all cancelable with immaterial or no cancellation penalties. Contract
terms are generally one year or less. We are currently committed to fund tenant-related capital improvements as described in the table above for executed leases. However, expected leasing levels could require additional tenant-related capital
improvements which are not currently committed. Due to the competitive office leasing market and higher vacancy rates, we expect that tenant-related capital costs will continue to remain high into 2006.

Unconsolidated Investments and Joint Ventures

We
have investments in real estate joint ventures in which we hold 21.2% to 49.0% interests. These investments are accounted for using the equity method and therefore the assets and liabilities of the joint ventures are not included in our financial
statements. These joint ventures own and operate office buildings financed by non-recourse debt obligations that are secured only by the real estate and other assets of the joint ventures. We have no obligation to repay these non-recourse debt
obligations and the lenders have no recourse to our other assets.

Our investments in these joint ventures are subject to risks not
inherent in our majority owned properties, including:



| |  |  | Absence of exclusive control over the development, financing, leasing, management and other aspects of the project;
| | - |  | -------------------------------------------------------------------------------------------------------------------



| |  |  | Possibility that our co-venturer or partner might:

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements, other than those
disclosed in our contractual obligations or as a guarantee, with any unconsolidated investments or joint ventures that have or are reasonably likely to have a future material effect on our financial condition, changes in our financial condition, our
revenue or expenses, our results of operations, our liquidity, our capital expenditures or our capital resources.

Guarantee Obligations

On June 30, 2004, CarrAmerica entered into a new $500.0 million, three-year unsecured revolving credit facility with JPMorgan Chase Bank as
administrative agent for a syndicate of banks. We are an unconditional guarantor of borrowings under this facility. The facility replaced and was used to repay all amounts outstanding under CarrAmericas previous senior unsecured credit
facility. CarrAmerica may increase the facility to $700.0 million by request at any time within 24 months of the closing, provided the funding commitments are increased accordingly. The facility can be extended one year at CarrAmericas option.
The facility carries an interest rate of 65 basis points over 30-day LIBOR, or 5.04% as of December 31, 2005. As of December 31, 2005, $120.0 million was drawn on the credit facility, $10.9 million in letters of credit were outstanding,
and CarrAmerica had $369.1 million available for borrowing.

We have unconditionally guaranteed unsecured notes issued by CarrAmerica to
institutional and other investors. The aggregate principal amount of the unsecured notes was $1.5 billion and $1.4 billion as of December 31, 2005 and 2004, respectively. These notes are in the following form:

CarrAmericas senior unsecured notes contain various covenants with which CarrAmerica must
comply. The covenants include:



| |  |  | Limits on total indebtedness on a consolidated basis;

| |  |  | Limits on secured indebtedness on a consolidated basis;
| | - |  | -------------------------------------------------------



| |  |  | Limits on required debt service payments; and
| | - |  | ---------------------------------------------

##### Table of Contents

$100.0 million of 6.625% senior unsecured notes matured March 1, 2005 and were repaid on that date
using borrowings from CarrAmericas unsecured credit facility. We expect we will be a guarantor on any new financing CarrAmerica may undertake.

CarrAmerica issued $250.0 million principal amount of senior unsecured notes in December 2005 with proceeds of approximately $247.5 million. The notes bear interest at 5.50% per annum payable semi-annually
beginning June 15, 2006. The notes mature on December 15, 2010. CarrAmerica used the proceeds from the notes to pay down its unsecured credit facility.

New Accounting Pronouncements

In December 2004, the FASB issued SFAS No. 123 (R), Share-Based
Compensation. It replaces SFAS No. 123, Accounting for Stock Issued to Employees. SFAS No. 123 (R) requires the compensation cost relating to share-based payment transaction be recognized in financial statements. It
is required to be applied for reporting periods beginning after January 1, 2006. CarrAmerica intends to adopt SFAS No. 123 (R) using the modified prospective application method which requires, among other things, that it recognize
compensation costs for all awards outstanding at January 1, 2006, for which the requisite service has not yet been rendered. Because CarrAmerica has used a fair value based method of accounting for stock based compensation costs for all
employee stock compensation awards granted, modified or settled since January 1, 2003, and do not expect to have significant unvested awards from periods prior to January 1, 2003 outstanding at January 1, 2006, adoption of SFAS
No. 123 (R) is not expected to have a material effect on compensation costs allocated to us by CarrAmerica.

Emerging Issues Task
Force (EITF) Issue 04-5, Determining Whether a General Partner or the General Partners, as a Group, Controls a Limited Partnership or Similar Entity When the Limited Partners Have Certain Rights was ratified by the FASB in
June 2005. At issue is what rights held by the limited partner(s) preclude consolidation in circumstances in which the sole general partner would consolidate the limited partnership in accordance with U.S. generally accepted accounting principles.
The assessment of limited partners rights and their impact on the presumption of control of the limited partnership by the sole general partner should be made when an investor becomes the sole general partner and should be reassessed if
(a) there is a change to the terms or in the exercisability of the rights of the limited partners, (b) the sole general partner increases or decreases its ownership of limited partnership interests, or (c) there is an increase or
decrease in the number of outstanding limited partnership interests. This Issue is effective no later than for fiscal years beginning after December 15, 2005 and as of June 29, 2005 for new and modified arrangements. We will not be
required to consolidate any of our current unconsolidated investments nor will this EITF have a material effect on our financial statements.

In March 2005, the FASB issued FASB Interpretation No. 47, Accounting for Conditional Asset Retirement Obligations. The Interpretation requires recognition of an asset and liability with regards to legal obligations
associated with the retirement of a tangible long-lived asset, such as the abatement of asbestos. The interpretation is effective for fiscal years ending after December 15, 2005. The adoption of FASB Interpretation No. 47 did not have any
effect on our financial statements.

Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our 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. We manage our 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.

Increases in interest rates would increase our interest
expense related to variable rate debt and adversely affect our cash flow. As of December 31, 2005, we had $27.0 million of variable rate debt due to CarrAmerica. The note requires interest only payments equal to 100 basis points over 30-day
LIBOR or 5.4% as of December 31, 2005 and matures on December 31, 2017.

A change in interest rates generally does not impact
future earnings and cash flows for fixed rate debt instruments. As fixed rate debt matures, and additional debt is incurred to fund the repayments of

maturing loans, 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 debt maturities at December 31, 2005:



|                    |  |   |       
|------------------- |  | - | ------
|(In Thousands)      |  |   |       
|2006                |  | $ | 1,120 
|2007                |  |   | 13,214
|2008                |  |   | 1,316 
|2009                |  |   | 13,858
|2010                |  |   | 1,132 
|2011 and thereafter |  |   | 65,073
|                    |  |   |

|                    |  |   |       

If we assume 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 market value of our fixed rate debt by approximately $1.6 million. The estimated
fair market value of the fixed rate debt instruments at December 31, 2005 and 2004 was $61.1 million and $77.6 million, respectively. A 10 percent change in the market interest rate on our variable debt would not result in a material change in
our interest expense.

CarrAmerica Realty, L.P.:

We have audited the consolidated financial statements of CarrAmerica Realty, L.P. and subsidiaries as listed in the accompanying index. In connection with our audits of the consolidated financial statements, we have also audited the
financial statement schedules as listed in the accompanying index. These consolidated financial statements and the financial statement schedules are the responsibility of the Partnerships management. Our responsibility is to express an opinion
on these consolidated financial statements and the financial statement schedules based on our audits.

We conducted our audits in
accordance with the standards of the Public Company Accounting Oversight Board (United States). 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, L.P. and subsidiaries as of December 31, 2005 and 2004, and the results of their
operations and their cash flows for each of the years in the three-year period ended December 31, 2005, in conformity with U.S. generally accepted accounting principles. Also in our opinion, the related financial statement schedules, when
considered in relation to the basic consolidated financial statements taken as a whole, present fairly, in all material respects, the information set forth herein.

Notes to Consolidated Financial Statements

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

(a) Business

We are a Delaware limited partnership formed on March 6, 1996 for the purpose of owning, acquiring
developing and operating office buildings across the United States. As of December 31, 2005, we owned a controlling interest in a portfolio of 53 operating office buildings. As of December 31, 2005 we also owned a minority interest in 30
operating office buildings. The properties are located in Austin, Chicago, Dallas, Denver, Orange County/Los Angeles, San Francisco Bay Area, Salt Lake City, San Diego, Seattle and Washington, D.C.

We are managed indirectly by CarrAmerica Realty Corporation, a fully integrated, self-administered and self-managed publicly traded real estate
investment trust (REIT). On June 30, 2004, CarrAmerica Realty Corporation contributed substantially all of it assets to CarrAmerica Realty Operating Partnership, L.P. (the Operating Partnership) in exchange for units of
common and preferred partnership interest in the Operating Partnership. The Operating Partnership assumed substantially all of CarrAmerica Realty Corporations liabilities (CarrAmerica Realty Corporation and CarrAmerica Realty Operating
Partnership, L.P. are collectively referred to hereafter as CarrAmerica). Our general partner is CarrAmerica Realty GP Holdings, Inc. (the General Partner), a wholly owned subsidiary of CarrAmerica. Our General Partner owned
a 1.0% interest in us at December 31, 2005. Our limited partners are CarrAmerica Realty LP Holdings, Inc., a wholly owned subsidiary of CarrAmerica, which owned an approximate 92.5% interest in us at December 31, 2005, and various other
individuals and entities, which collectively owned an approximate 6.5% interest in us at December 31, 2005.

(b) Basis of Presentation

Our accounts and those of our controlled subsidiaries and affiliates are consolidated in the financial statements. We consolidate all
entities in which we own a direct or indirect majority voting interest and where the minority holders do not have rights to participate in significant decisions that are made in the ordinary course of business. If applicable, we would consolidate
any variable interest entity of which we are the primary beneficiary. We use the equity method to account for our investments in and our share of the earnings or losses of unconsolidated entities. These entities are not controlled by us. If events
or changes in circumstances indicate that the fair value of an investment accounted for using the equity method has declined below its carrying value and we consider the decline to be other than temporary, the investment is written down
to fair value and an impairment loss is recognized.

Management has made a number of estimates and assumptions that affect the reported
amounts of assets, liabilities, revenues and expenses in the financial statements, and the disclosure of contingent assets and liabilities. Estimates are required in order for us to prepare our financial statements in conformity with U.S. generally
accepted accounting principles. Significant estimates are required in a number of areas, including the depreciable lives of assets, evaluating the impairment of long-lived assets, allocating the purchase cost of acquired properties and evaluating
the collectibility of accounts receivable. Actual results could differ from these estimates.

In accordance with its established practices,
CarrAmerica allocates certain general and administrative expenses to its subsidiaries, including us. CarrAmerica allocates certain general expenses to subsidiaries based on their respective share of total assets. Expenses allocated to us by
CarrAmerica in 2005, 2004, and 2003 were $7.0 million, $5.7 million, and $6.0 million, respectively.

Effective January 1, 2004, all
of our employees were transferred to and became employees of CarrAmerica. We contract with CarrAmerica for their services. During 2005 and 2004, CarrAmerica charged us for the compensation costs of approximately 41 and 57, respectively, on-site
employees. The compensation cost charged to us by CarrAmerica for these employees is equivalent to the cost we would have incurred if we were their employer. The compensation cost is charged separately from the general and administrative cost
allocation made to us by CarrAmerica.

(c) Rental Property

Properties to be developed or held and used in rental operations are carried at cost less accumulated depreciation and impairment losses, where appropriate. Properties held for sale are carried at the lower of their
carrying values (i.e., cost less accumulated depreciation and impairment losses, where appropriate) or estimated fair value less costs to sell. Properties are considered held for sale when they are subject to a contract of sale meeting criteria
specified by senior management (e.g., contingencies are met or waived, a nonrefundable deposit is paid, etc.). Depreciation on these properties is discontinued at that time, but operating revenues, other operating expenses and interest continue to
be recognized until the date of sale. Revenues and expenses of properties that are classified as held for sale or sold are presented as discontinued operations for all periods presented in the Statements of Operations if the properties will be or
have been sold on terms where we have limited or no continuing involvement with them after the sale. As of December 31, 2005 no properties are classified as held for sale.

Depreciation of rental properties is computed on a straight-line basis over the estimated useful lives of the assets. The estimated lives of our assets
by class are as follows:



|                                  |  |                                                                
|--------------------------------- |  | ---------------------------------------------------------------
|Base building                     |  | 20-40 years                                                    
|Building components               |  | 7 to 20 years                                                  
|Tenant improvements               |  | Lesser of the terms of the leases or useful lives of the assets
|Furniture, fixtures and equipment |  | 5 to 15 years                                                  

Specifically identifiable costs associated with properties and land under development are
capitalized. Capitalized costs may include salaries and related costs, real estate taxes, interest, pre-construction costs essential to the development of a property, development costs, and external acquisition costs. Costs of significant
improvements, renovations and replacements to rental properties are capitalized. Expenditures for maintenance and repairs are charged to operations as they are incurred.

If events or changes in circumstances indicate that the carrying value of a rental property to be held and used or land held for development may be impaired, we perform a recoverability analysis based on estimated
undiscounted cash flows to be generated from the property in the future. If the analysis indicates that the carrying value is not recoverable from future cash flows, the property is written down to estimated fair value and an impairment loss is
recognized.

We recognize gains from sales of rental properties and land at the time of sale using the full accrual method, provided that
various criteria related to the terms of the transactions and any subsequent involvement by us with the properties sold are met. If the criteria are not met, we defer the gains and recognize them when the criteria are met or use the installment or
cost recovery methods, as appropriate in the circumstances.

(d) Property Acquisitions

We allocate the purchase cost of acquired properties to the related physical assets and in-place leases based on their fair values.

The fair values of acquired office buildings are determined on an if-vacant basis considering a variety of factors, including the physical
condition and quality of the buildings, estimated rental and absorption rates, estimated future cash flows and valuation assumptions consistent with current market conditions. The if-vacant fair value is allocated to land, where
applicable, buildings, tenant improvements and equipment based on property tax assessments and other relevant information obtained in connection with the acquisition of the property.

The fair value of in-place leases includes the effect of leases with above or below market rents, customer relationship value, where applicable, and the
cost of acquiring existing tenants at the date of acquisition. Above market and below market in-place lease values are determined on a lease by lease basis based on the present value (using an interest rate which reflects the risks associated with
the leases acquired) of the difference between (a) the contractual amounts to be paid under the lease and (b) our estimate of fair market lease rate for the corresponding space over the remaining non-cancelable terms of the related leases.
The

capitalized below market lease values are amortized as an increase to rental revenue over the initial term and any below market renewal periods of the
related leases. Capitalized above market lease values are amortized as a decrease to rental revenue over the initial term of the related leases. Customer relationship values are determined based on our evaluation of the specific characteristics of
each tenants lease and our overall relationship with the tenant. Characteristics we consider included the nature and extent of our existing business relationships with the tenant, prospects for developing new business with the tenant, the
tenants credit quality and expectations of lease renewals. The value of customer relationship intangibles is amortized to expense over the lesser of the initial lease term and any expected renewal periods or the remaining useful life of the
building. We determine the fair value of the cost of acquiring existing tenants by estimating the lease commissions avoided by having in-place tenants and lost operating income for the estimated period required to lease the space occupied by
existing tenants at the acquisition date. The cost of acquiring existing tenants is amortized to expense over the initial term of the respective leases. Should a tenant terminate its lease, the unamortized portion of the in-place lease value is
charged to expense. Changes in the assumptions used in the allocation of the purchase cost among the acquired assets would affect the timing of recognition of the related revenue and expenses.

(e) Geographic Concentration

As of December 31,
2005, we owned greater than 50% interests in 53 operating office buildings located in the United States. The following table summarizes the number of buildings, the rentable square footage and the percentage of property operating income by market.

|1 | Property operating income is property operations revenue less property operating expenses.
|- | ------------------------------------------------------------------------------------------

(f) Tenant Leasing Costs

We defer fees and initial direct costs incurred in the negotiation of
completed leases. They are amortized on a straight-line basis over the term of the lease to which they apply.

(g) Fair Values of Financial Instruments

The carrying amounts of accounts receivable and accounts payable and accrued expenses approximate their fair values because of their
short-term maturities. Fair value information relating to mortgages and notes payable is provided in note 3.

(h) Revenue Recognition

We commence revenue recognition on our leases based on a number of factors. In most cases, revenue recognition under a lease begins when the lessee takes
possession of or controls the physical use of the leased asset. Generally, this occurs on the lease commencement date. In determining what constitutes the leased asset, we evaluate whether we or the lessee are the owner, for accounting purposes, of
the tenant improvements. If we

Notes to Consolidated Financial Statements



are the owner, for accounting purposes, of the tenant improvements, then the leased asset is the finished space and revenue recognition begins when the
lessee takes possession of the finished space, typically when the improvements are substantially complete. If we conclude we are not the owner, for accounting purposes, of the tenant improvements (the lessee is the owner), then any tenant
improvement allowances funded under the lease are treated as lease incentives and the leased asset is the unimproved space. In these circumstances, we begin revenue recognition when the lessee takes possession of the unimproved space for the lessee
to construct improvements. The determination of who is the owner, for accounting purposes, of the tenant improvements determines the nature of the leased asset and when revenue recognition under a lease begins. We consider a number of different
factors to evaluate whether we or the lessee is the owner of the tenant improvements for accounting purposes. These criteria include:



| |  |  | whether the lease stipulates how and on what a tenant improvement allowance may be spent;
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | whether the tenant or landlord retain legal title to the improvements;
| | - |  | ----------------------------------------------------------------------



| |  |  | the uniqueness of the improvements;
| | - |  | -----------------------------------



| |  |  | the expected economic life of the tenant improvements relative to the length of the lease; and
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | who constructs or directs the construction of the improvements.
| | - |  | ---------------------------------------------------------------

The
determination of who owns the tenant improvements, for accounting purposes, is subject to significant judgment. In making that determination we consider all of the above factors, however, no one factor is determinative in reaching a conclusion.

If a lease provides for rent based on the resolution of contingencies, such as meeting a level of sales by the tenant, we defer rent
associated with rental contingencies until the resolution of the contingency.

We recognize lease termination fees on the termination date
or over the shortened remaining term of the lease. We recognized lease termination fees of $1.6 million, $0.6 million and $0.7 million in 2005, 2004 and 2003, respectively. These fees are included in other tenant charges in the statements of
operations.

We recognize revenue for services on properties we manage, lease or develop for unconsolidated entities or third parties when
the services are performed. Revenue for development and leasing services to affiliates is reduced to eliminate profit to the extent of our ownership interest.

We provide for potentially uncollectible accounts and notes receivable and accrued straight-line rents based on analysis of the risk of loss on specific accounts. The analysis places particular emphasis on past-due
accounts and considers information such as the nature and age of the receivable, the payment history of the tenant or other debtor, the financial condition of the tenant and our assessment of its ability to meet its lease obligations, the basis for
any disputes and the status of related negotiations, etc. During 2005, 2004, and 2003, we recognized bad debt expense of $0.2 million, $0.6 million, and $0.7 million, respectively.

(i) Taxes

We generally make no provision for federal and state income taxes because the partners
report their share of our taxable income or loss and any available tax credits on their income tax returns. In limited cases, however, we are subject to certain state and local taxes. We recorded a contingency of $0.7 million in 2005 related to
state and local taxes. The aggregate cost of land and depreciable property net of accumulated tax depreciation, for federal income tax purposes as of December 31, 2005 and 2004 was approximately $552 million and $546 million, respectively. As
of December 31, 2005 our net book basis in depreciable assets exceeded our net tax basis by $68.4 million. We did not pay any income taxes for the years ended December 31, 2005, 2004 and 2003.

(j) Cash Equivalents

We consider all highly liquid
investments with a maturity of three months or less at the date of purchase to be cash equivalents except that any such investments purchased with funds on deposit in escrow or similar accounts are classified as restricted deposits.

(k) New Accounting Pronouncements

In December 2004, the FASB issued SFAS No. 123 (R), Share-Based Compensation. It replaces SFAS No. 123, Accounting for Stock
Issued to Employees. SFAS No. 123 (R) requires the compensation cost relating to share-based payment transaction be recognized in financial statements. It is required to be applied for reporting periods beginning after
January 1, 2006. CarrAmerica intends to adopt SFAS No. 123 (R) using the modified prospective application method which requires, among other things, that it recognize compensation costs for all awards outstanding at January 1,
2006, for which the requisite service has not yet been rendered. Because CarrAmerica has used a fair value based method of accounting for stock based compensation costs for all employee stock compensation awards granted, modified or settled since
January 1, 2003, and do not expect to have significant unvested awards from periods prior to January 1, 2003 outstanding at January 1, 2006, adoption of SFAS No. 123 (R) is not expected to have a material effect on
compensation costs allocated to us by CarrAmerica.

Emerging Issues Task Force (EITF) Issue 04-5, Determining Whether a
General Partner or the General Partners, as a Group, Controls a Limited Partnership or Similar Entity When the Limited Partners Have Certain Rights was ratified by the FASB in June 2005. At issue is what rights held by the limited partner(s)
preclude consolidation in circumstances in which the sole general partner would consolidate the limited partnership in accordance with U.S. generally accepted accounting principles. The assessment of limited partners rights and their impact on
the presumption of control of the limited partnership by the sole general partner should be made when an investor becomes the sole general partner and should be reassessed if (a) there is a change to the terms or in the exercisability of the
rights of the limited partners, (b) the sole general partner increases or decreases its ownership of limited partnership interests, or (c) there is an increase or decrease in the number of outstanding limited partnership interests. This
Issue is effective no later than for fiscal years beginning after December 15, 2005 and as of June 29, 2005 for new and modified arrangements. We will not be required to consolidate any of our current unconsolidated investments nor will
this EITF have a material effect on our financial statements.

In March 2005, the FASB issued FASB Interpretation No. 47,
Accounting for Conditional Asset Retirement Obligations. The Interpretation requires recognition of an asset and liability with regards to legal obligations associated with the retirement of a tangible long-lived asset, such as the
abatement of asbestos. The interpretation is effective for fiscal years ending after December 15, 2005. The adoption of FASB Interpretation No. 47 did not have any effect on our financial statements.

(2) Mandatorily Redeemable Partnership Units

Our ownership is expressed in partnership units (Units). These Units are redeemable at the option of the holders for, as determined by CarrAmerica, a like number of shares of common stock of CarrAmerica or cash. Since
these Units are redeemable at the option of the holders and this decision is outside our control, they are classified outside partners capital on the balance sheet as redeemable partnership units and measured at the redemption value as of the
end of the periods presented. As of December 31, 2005 and December 31, 2004, there were 929,522 and 1,126,918 redeemable Units outstanding, respectively. The value of the redeemable Units is based on the closing market price of CarrAmerica
common stock, which was $34.63 per share as of December 31, 2005 and $33.00 per share as of December 31, 2004.

(3) Mortgages and Notes
Payable

Our mortgages and notes payable are summarized as follows:

Mortgages payable are collateralized by properties and generally require monthly principal and/or
interest payments. The mortgages payable outstanding at December 31, 2005 mature in 2009. The weighted average interest rate of fixed rate mortgages and notes payable was 7.44% at December 31, 2005 and 7.77% at December 31, 2004. The
weighted average interest rate of our fixed rate mortgages, excluding the notes payable to affiliate, was 7.13% as of December 31, 2005 and 6.91% as of December 31, 2004. We repaid $17.9 million of fixed rate debt with a portion of the
sale proceeds from our 2600 West Olive property. Related to the extinguishment, we incurred $1.2 million of prepayment penalties which are included in discontinued operations since we were required to repay the mortgage when we sold the related
property. During 2004, we repaid $40.3 million of fixed rate debt, of which $29.8 million was extinguished early. In connection with these extinguishments, we borrowed $19.5 million under a variable rate note from CarrAmerica and incurred prepayment
penalties of $0.8 million, which are included in interest expense in 2004.

We have four loans with CarrAmerica. The first is a $30.0
million loan (balance at December 31, 2005 of $24.9 million) that bears interest at 8.5%, requires monthly principal and interest payments of $242,000 and matures on May 31, 2011. The second is a $12.0 million loan that bears interest at
8.5% and requires monthly interest only payments of $85,000 and matures on March 27, 2007. The third note in a principal amount of $27.0 million, requires interest only payments equal to 100 basis points over 30-day LIBOR (5.4% as of
December 31, 2005) and matures on December 31, 2017. The fourth note is a $18.0 million loan that bears interest at 5.5% and requires monthly interest only payments of $82,500 and matures on November 30, 2015. Total interest paid to
CarrAmerica under these loans was $4.5 million in 2005 and $3.3 million in 2004 and 2003.

On June 30, 2004, CarrAmerica entered into
a new $500.0 million, three-year unsecured revolving credit facility with JPMorgan Chase Bank as administrative agent for a syndicate of banks. We are an unconditional guarantor of borrowings under this facility. The facility replaced and was used
to repay all amounts outstanding under CarrAmericas previous unsecured senior credit facility. CarrAmerica may increase the facility to $700.0 million by request at any time within 24 months of the closing, provided the funding commitments are
increased accordingly. The facility can be extended one year at CarrAmericas option. The facility carries an interest rate of 65 basis points over 30-day LIBOR, or 5.04% as of December 31, 2005. As of December 31, 2005, $120.0
million was drawn on the credit facility, $10.9 million in letters of credit were outstanding, and we had $369.1 million available for borrowing.

CarrAmericas unsecured credit facility contains financial and other covenants with which it must comply. Some of these covenants include:



| |  |  | A minimum ratio of annual EBITDA (earnings before interest, taxes, depreciation and amortization) to interest expense of at least 2 to 1;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------



| |  |  | A minimum ratio of annual EBITDA to fixed charges of at least 1.5 to 1;
| | - |  | -----------------------------------------------------------------------



| |  |  | A maximum ratio of aggregate unsecured debt to tangible fair market value of its unencumbered assets of 60%;
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | A maximum ratio of total secured debt to tangible fair market value of 30%;
| | - |  | ---------------------------------------------------------------------------



| |  |  | A maximum ratio of total debt to tangible fair market value of CarrAmericas assets of 60%; and
| | - |  | -----------------------------------------------------------------------------------------------



| |  |  | Restrictions on its ability to make dividend distributions in excess of 90% of funds from operations or the minimum amount necessary to enable CarrAmerica to maintain its status as
a REIT.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

As of December 31, 2005, CarrAmerica was in compliance with all of its debt covenants; however, its ability to
draw on the unsecured credit facility or incur other unsecured debt in the future could be restricted by the loan covenants.

|                    |  |   |       

The estimated fair value of our mortgages payable and fixed rate notes payable to affiliate at
December 31, 2005 and 2004 was approximately $61.1million and $77.6 million, respectively. The estimated fair value is based on the borrowing rates available to us for fixed rate mortgages payable with similar terms and average maturities. A
total of 28.2% ($27.0 million) of our total debt was subject to variable interest rates.

(4) Partners Capital Contributions, Distributions and
Participation Percentages

Our Third Amended and Restated Agreement of Limited Partnership, as amended (the Partnership
Agreement) details the rights of our owners. Our ownership is expressed in units. Units currently are designated as Class A, B, C, D or E Units. Class D Units have first preference. Class A and Class E Units together have second
preference and Class B Units have third preference as to the allocation of available cash (defined in the Partnership Agreement). Class C Units do not share in the allocation of available cash. All Class C Units have been converted to Class A
Units. Class E Units receive a special allocation for losses. At December 31, 2005 and 2004, affiliates of CarrAmerica owned all of our outstanding Class B Units.

Each holder of Class A Units, Class D Units or Class E Units may require us to redeem their units. Redemption is subject to certain limitations. Upon redemption of a unit, the holder will receive, at
CarrAmericas option, either (i) cash in the amount equal to the market value of one share of CarrAmerica common stock (subject to certain anti-dilution adjustments) or (ii) one share of CarrAmerica common stock. In lieu of us
redeeming Class A, Class D or Class E Units for cash, CarrAmerica has the right to assume directly and satisfy the redemption right of a unit holder. Holders of Class B Units are not entitled to exercise this redemption right.

Units outstanding were as follows:



|              |  |                  |  |                  |  |

During 2005, we made total distributions of $2.0 million to holders of Class A Units, Class D
Units and Class E Units. During 2004, we made total distributions of $10.6 million to unit holders. $8.4 million of the $10.6 million was paid to CarrAmerica, or Class B Unit holders, the remainder was distributed to holders of Class A, Class D
and Class E Units.

(5) Lease Agreements

Space in our rental properties is leased to approximately 339 tenants. In addition to minimum rents, the leases typically provide for other rents which reimburse us for specific property operating expenses. The future minimum base rent to
be received under noncancellable tenant operating leases and the percentage of total rentable space under leases expiring each year, as of December 31, 2005 are summarized as follows:

Often, leases contain fixed increases in additional rent based on increases in the Consumer Price
Index (CPI) and increases in operating expenses. Increases are generally payable in equal installments throughout the year.

(6) Investments in
Unconsolidated Entities and Affiliate Transactions

We utilize joint venture arrangements on projects characterized by large
dollar-per-square foot costs and/or when we desire to limit capital deployment in certain of its markets. We own interests ranging from 21.2% to 49.0% in real estate properties through unconsolidated entities. We had three investments as of
December 31, 2005, 2004 and 2003.

The combined condensed financial information for the unconsolidated entities accounted for using
the equity method is as follows:

During the twelve months ended December 31, 2005, we disposed of our Phoenix portfolio, 2600
West Olive, Two Mission, and the Quorum properties in Dallas, Texas. Prior to the sale of the Phoenix and Quorum buildings, we recognized impairment losses of $6.7 million. We recognized gains of approximately $25,000 and $63,000, respectively, on
these transactions, which along with the properties results of operations, are classified as discontinued operations as we have no continuing involvement with the properties after the sales. In addition, we completed the sale of the Phoenix
portfolio and sold 2600 West Olive and Two Mission during the fourth quarter of 2005. We recognized gains of $16.6 million, which along with the properties results of operations, are classified as discontinued operations as we have no
continuing involvement with the properties after the sales. A joint venture in which we owned a 21.2% interest, sold an office building in June 2005. We recognized a gain of $0.5 million on the sale and received cash proceeds of $3.5 million.

We disposed of our Tower of the Hills property in the first quarter of 2004, resulting in proceeds of approximately $10.5 million and
recognized a gain of $0.1 million. We previously recognized an impairment loss of $3.0 million on this property in the fourth quarter of 2003. We have no continuing involvement with the Tower of the Hills property after the sale and accordingly, the
gain on this sale, the impairment loss and the operating results of this property are classified as discontinued operations.

During 2003,
we did not dispose of any real estate properties although we reduced a previously recognized gain by $0.4 million for additional costs related to a sold property.

(9) Commitments and Contingencies

Prior to
January 1, 2004, we participated in CarrAmericas 401(k) plan for employees. Our contributions to the plan were $312,000 in 2003. In 2004, all of our employees transferred to and are now employed by affiliates of CarrAmerica.

We are party to a variety of legal proceedings arising in the ordinary course of business. All of these matters, taken together, are not expected to
have a material adverse impact on us. Based on currently available facts, we believe that the disposition of matters that are pending or asserted will not have a material adverse effect on our consolidated financial position, results of operations
or liquidity.

On June 30, 2004, CarrAmerica entered into a new $500.0 million, three-year unsecured revolving credit facility with
JPMorgan Chase Bank as administrative agent for a syndicate of banks. We are an unconditional guarantor of borrowings under this facility. The facility replaced and was used to repay all amounts outstanding under CarrAmericas previous senior
unsecured credit facility. CarrAmerica may increase the facility to $700.0 million by request at any time within 24 months of the closing, provided the funding

commitments are increased accordingly. The facility can be extended one year at CarrAmericas option. The facility carries an interest rate of 65 basis
points over 30-day LIBOR, or 5.04% as of December 31, 2005. As of December 31, 2005, $120.0 million was drawn on the credit facility, $10.9 million in letters of credit were outstanding, and CarrAmerica had $369.1 million available for
borrowing.

We have unconditionally guaranteed unsecured notes issued by CarrAmerica to institutional investors. The aggregate principal
amount of the unsecured notes was $1.5 billion as of December 31, 2005. These notes are in the following form:
