              Notes to Condensed Consolidated Financial Statements
                                   (Unaudited)
- --------------------------------------------------------------------------------

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

         (a)      Business

                  CarrAmerica Realty Corporation (the "Company") is a
                  self-administered and self-managed equity real estate
                  investment trust ("REIT"), organized under the laws of
                  Maryland, which owns, develops, acquires and operates office
                  properties. The Company's office properties are located
                  primarily in 15 suburban markets across the United States.

         (b)      Basis of Presentation

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

         (c)      Interim Financial Statements

                  The information furnished reflects all adjustments which are,
                  in the opinion of management, necessary to reflect a fair
                  presentation of the results for the interim periods, and all
                  such adjustments are of a normal, recurring nature.

         (d)      Rental Property

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

                  Base Building.............................30 to 50 years
                  Building components.......................7 to 20 years
                  Tenant improvements.......................Terms of the leases
                                                            or useful lives,
                                                            whichever is
                                                            shorter
                  Furniture, fixtures and equipment.........5 to 15 years

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

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

         (e)      Development Property

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

         (f)      Tenant Leasing Costs

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

         (g)      Deferred Financing Costs

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

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

                  Real estate service contracts and other intangible assets
                  represent the purchase price of net assets of real estate
                  service operations acquired and are amortized on the
                  straight-line basis over the expected lives of the respective
                  real estate service contracts. Goodwill, which represents the
                  excess of purchase price over the fair value of net assets
                  acquired in the acquisition of executive suite businesses, is
                  amortized on the straight-line basis over 30 years. The
                  Company assesses the recoverability of these intangible assets
                  by determining whether the balance can be recovered over its
                  remaining life through undiscounted future operating cash
                  flows of the related assets or operations acquired. The amount
                  of impairment loss, if any, is measured as the amount by which
                  the carrying amount of the assets exceeds the fair value of
                  the assets. The assessment of the recoverability of these
                  intangible assets will be impacted if estimated future
                  operating cash flows are not achieved.

         (i)      Fair Value of Financial Instruments

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

         (j)      Revenue Recognition

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

                  The Company earns real estate service revenue for certain
                  properties it manages, leases and develops for third parties.
                  Executive suites revenue represents rental income from
                  executive suites customers and income from various services
                  provided to these customers, such as, telephone and
                  administrative support. Such revenue is recognized as earned.

         (k)      New Accounting Pronouncements

                  In June 1997, the Financial Accounting Standards Board (FASB)
                  issued SFAS No. 130, "Reporting Comprehensive Income," which
                  requires an enterprise to display comprehensive income and its
                  components in a financial statement to be included in an
                  enterprise's full set of financial statements. Comprehensive
                  income represents a measure of all changes in equity of an
                  enterprise that result from recognized transactions and other
                  economic events for the period other than transactions with

                  owners in their capacity as owners. Comprehensive income
                  includes net income and such items as foreign currency items
                  and certain unrealized gains and losses. For the three and
                  nine month periods ended September 30, 1998, foreign currency
                  translation adjustments were $685 and $1,472, respectively,
                  net of tax. Therefore, comprehensive income was $37,066 and
                  $112,469, respectively, for the three and nine month periods
                  ended September 30, 1998.

                  In June 1997, the Financial Accounting Standards Board issued
                  Statement of Financial Accounting Standards No. 131 (FAS No.
                  131), "Disclosure about Segment of an Enterprise and Related
                  Information." FAS No. 131 requires the Company to present
                  certain information about operating segments and related
                  information, including geographic and major customer data, in
                  its annual financial statements and in condensed financial
                  statements for interim periods. The Company is required to
                  adopt the provisions of this statement during fiscal year 1998
                  and plans to implement the provisions of this statement at
                  December 31,1998. Management is currently determining the
                  necessary additional disclosures, if any.

                  In June 1998, the FASB issued SFAS No. 133 "Accounting for
                  Derivative Instruments and Hedging Activities", which requires
                  that an entity recognize all derivatives as either assets or
                  liabilities in the statement of financial position and measure
                  those instruments at fair value. This statement is effective
                  for all fiscal quarters of fiscal years beginning after June
                  15, 1999. The Company has not yet determined the impact of
                  this pronouncement, if any.

         (l)      Income and Other Taxes

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

                  Certain subsidiaries, organized as partnerships, of the
                  Company are subject to District of Columbia franchise taxes.
                  Franchise taxes are recorded as general and administrative
                  expenses in the accompanying consolidated financial
                  statements.

                  CarrAmerica Development, Inc. ("CarrAmerica Development"), the
                  Company's development subsidiary, Carr Real Estate Services,
                  Inc. ("Carr Services, Inc."), the Company's real estate
                  service subsidiary, OmniOffices, Inc. ("OmniOffices"), and
                  OmniOffices (UK) Limited ("Omni-UK"), the Company's executive
                  suites subsidiaries, file separate tax returns and are subject
                  to federal, state and local income taxes as well as certain
                  foreign taxes. The Company has adopted the asset and liability
                  method of accounting for income taxes for these subsidiaries.
                  Under the asset and liability method, deferred tax assets and
                  liabilities are recognized for the future tax consequences
                  attributable to temporary differences between the financial
                  statement carrying amounts of existing assets and liabilities
                  and their respective tax bases and to operating loss and tax
                  credit carryforwards. Deferred tax assets and liabilities are
                  measured using enacted tax rates expected to apply to taxable
                  income in the years in which those temporary differences are
                  expected to be recovered or settled. The effect on deferred
                  tax assets and liabilities of a change in tax rates is
                  recognized in income in the period of the enactment date.

         (m)      Hedging Transactions

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

          (n)     Per Share Data and Dividends

                  Effective December 31, 1997, the Company adopted the
                  provisions of SFAS No. 128 "Earnings Per Share." SFAS No. 128
                  supersedes APB No. 15 and specifies computation, presentation
                  and disclosure requirements for EPS and requires restatement
                  of prior years' comparative EPS amounts. The following is a
                  reconciliation of the numerators and denominators of the basic
                  and diluted EPS computations for income before extraordinary

         (o)      Cash Equivalents

                  For the purposes of reporting cash flows, the Company
                  considers all highly liquid investments with a maturity of
                  three months or less at the time of purchase to be cash
                  equivalents.

                  The financial statements of Omni-UK, a foreign subsidiary,
                  have been prepared in the respective local currency and
                  translated into U.S. dollars based on the current exchange
                  rate at the end of the period for assets and liabilities and
                  at an average exchange rate for the period on the statement of
                  operations. Translation adjustments have no effect on net
                  income and are reflected in Stockholders' Equity as
                  accumulated other comprehensive income.

         Mortgages payable are collateralized by certain rental properties and
         generally require monthly principal and/or interest payments. Mortgages
         payable mature at various dates from December 1998 through July 2019.
         The weighted average interest rate of mortgages payable was 8.2% at
         September 30, 1998 and 8.1% at December 31, 1997. In compliance with
         the terms of the mortgage instrument, a mortgage payable of $27.4
         million at September 30, 1998 is held by Carr Redmond Corporation, a
         wholly-owned subsidiary of the Company, which owns the Redmond East
         office campus.

         The Company has a $450.0 million unsecured credit facility with Morgan
         Guaranty Trust Company of New York (Morgan), as agent for a group of
         banks. At September 30, 1998, the credit facility bore interest, as
         selected by the Company, at either (i) the higher of the prime rate or
         the Federal Funds Rate for such day or (ii) an interest rate equal to
         90 basis points above the 30 day London Interbank Offered Rate (LIBOR).
         The Company has predominately selected interest rates equal to 90 basis
         points above the 30 day LIBOR rate for initial draws and upon the
         expiration of current LIBOR contracts. The credit facility matures in
         August 2001.

         OmniOffices also has a $200.0 million unsecured credit facility with
         Morgan, as agent for a group of banks. At September 30, 1998, the
         credit facility bore interest, as selected by OmniOffices, at either

         or (ii) an interest rate equal to 90 basis points above the 30 day
         LIBOR. OmniOffices has predominately selected interest rates equal to
         90 basis points above the 30 day LIBOR rate for initial draws and upon
         the expiration of current LIBOR contracts. The credit facility matures
         in August 2001. The facility is unconditionally guaranteed by the
         Company.

                                                          ==========

                      (1)  Includes $448 million outstanding as of September 30,
                           1998 under the Company's $450 million unsecured line
                           of credit.

                      (2)  Includes $99.5 million outstanding as of September

                      (3)  Includes $475 million of senior unsecured notes, $150
                           million of which matures in 2004, $100 million of
                           which matures in 2005, $125 million of which matures

         by lenders to be used for future building renovations or tenant
         improvements, escrow deposits for the acquisition of executive suites
         assets and collateral for letters of credit.

(3)      Minority Interest

         In conjunction with the formation of the Company and its majority-owned
         subsidiary, Carr Realty, L.P., persons contributing interests in
         properties to Carr Realty, L.P. had the right to elect to receive
         either common stock of the Company or Units in Carr Realty, L.P. In
         addition, the Company has acquired certain assets since its formation
         by issuing distribution paying Units and non-distribution paying Units
         of Carr Realty, L.P. and CarrAmerica Realty, L.P. The non-distribution
         paying Units are not entitled to any distributions until they
         automatically convert into distribution paying Units at various dates
         in the future. Each distribution paying Unit, subject to certain
         restrictions, may be redeemed for either one share of common stock or,
         at the option of the Company, cash equal to the fair market value of a
         share of common stock at the time of the redemption. When a Unitholder
         redeems a distribution paying Unit for a share of common stock or cash,
         minority interest is reduced and the Company's investment in Carr
         Realty, L.P. or CarrAmerica Realty, L.P., as the case may be, is
         increased. During the three and nine month periods ended September 30,
         1998, 10,421 and 24,897 distribution paying Units, respectively, of
         Carr Realty, L.P. and CarrAmerica Realty, L.P., were redeemed for
         common stock of the Company.

         The following table sets forth the common stock and preferred stock
         which is convertible into common stock of the Company and Units of Carr
         Realty, L.P. and CarrAmerica Realty, L.P. (in thousands):

         Minority interest in the accompanying consolidated financial statements
         relates primarily to holders of Units.


(4)      Preferred Stock

         The Company is authorized to issue up to 35,000,000 shares of Preferred
         Stock. On October 25, 1996, the Company issued 1,740,000 shares of
         Series A Cumulative Convertible Redeemable Preferred Stock ("Series A
         Preferred Stock") at $25 per share. Dividends for the Series A
         Preferred Stock are cumulative from the date of issuance and are
         payable quarterly in arrears in an amount per share equal to the
         greater of (1) $1.75 per share per annum, or (2) the cash dividend paid
         on the number of shares, or portion thereof, of the Company's common
         stock into which a share of Series A Preferred Stock is convertible.
         The Series A Preferred Stock has a liquidation preference of $25 per
         share. After April 25, 1997, each share of Series A Preferred Stock
         became convertible, at the option of the holder, into one share of the
         Company's common stock, subject to certain conversion adjustments. As
         of September 30, 1998, 1,060,000 shares of Series A Preferred Stock had
         been converted into the Company's common stock. After October 25, 1999,
         each outstanding share of Series A Preferred Stock is redeemable at the
         Company's option, at $25 per share, plus accrued and unpaid dividends.

         Series C and D shares listed above are Depositary Shares, each
         representing a 1/10 fractional interest in a share of preferred stock.

(5)      Gain on Sale of Assets

         The Company has disposed of certain assets that are inconsistent with
         its long-term strategic or return objectives or where market conditions
         for sale are favorable. The proceeds of the sales were redeployed into
         other office properties (utilizing tax-deferred exchanges where
         possible). During the first nine months of 1998, the Company disposed
         of two operating properties and land that was being held for
         development. The Company recognized a gain totaling $33.0 million on
         these dispositions.

         At September 30, 1998, the Company is contingentally liable on letters
         of credit amounting to approximately $6.5 million for various
         completion escrows and on performance bonds amounting to approximately
         $11.8 million to ensure completion of required public improvements on
         its construction projects.

         On June 22, 1998, the Company entered into an interest rate hedge
         agreement in the notional amount of $200.0 million at a rate of 9.5% in
         order to hedge against the impact that interest rate fluctuations would
         have on the interest rate attainable on the Company's line of credit.
         As of September 30, 1998, unrealized gain/loss on the agreement was
         zero.

(7)      Subsequent Events

         From October 1 to November 14, 1998, the Company acquired two office
         properties. The Company paid $36.2 million in cash to purchase the
         properties. These acquisitions added to the Company's holdings as
         follows:

                           Total                    2              238,000
                                              =============      ===========

         In April 1998, the Company sold 5,000,000 shares of common stock to
         Merrill Lynch, Pierce, Fenner & Smith Incorporated ("Merrill Lynch"),
         resulting in net proceeds to the Company of approximately $147 million,
         in what is commonly known as a "forward equity sale" transaction. In
         connection with that transaction, the Company entered into an agreement
         with Merrill Lynch under which the parties agreed to adjust the number
         of shares of common stock issued to Merrill Lynch (or the aggregate
         purchase price paid for such shares) based upon the proceeds received
         by Merrill Lynch upon a resale of the shares by April 1999 in relation
         to the amount originally paid by Merrill Lynch ($150 million), plus a
         forward accretion component and less dividends paid on the shares. The
         final settlement under the agreement will occur no later than April
         1999, although Merrill Lynch has the right to cause an earlier
         settlement if the market price of the Company's common stock declines
         below certain levels. At monthly intervals up until the final
         settlement, CarrAmerica is required to deposit into escrow either cash
         or additional shares of common stock if the market price of the
         Company's common stock declines. As a result of declines in the market
         price of the Company's common stock, the Company deposited $39.3
         million in cash with Merrill Lynch over various times between April
         1998 and October 5, 1998.

         On October 5, 1998, the Company and Merrill Lynch entered into an
         amendment to the agreement pursuant to which the Company paid to
         Merrill Lynch the $39.3 million currently on deposit, and in connection
         therewith the aggregate settlement amount under the agreement was
         reduced from $150 million to $112 million (i.e, the purchase price
         adjustment mechanism takes effect if the aggregate proceeds received by
         Merrill Lynch from the sale of the 5,000,000 shares is less than or
         greater than $112 million), plus a forward accretion component and less
         dividends paid on the shares. The effect of this amendment is to permit
         the Company to benefit from the increase in the market price of its
         common stock over $22.40, but also subjects the Company to the risk
         that it may have to deliver additional shares or return a portion of
         the purchase price if there is a decrease in the market price of its
         common stock below $22.40. The final settlement under the agreement
         remains no later than April 1999.

Item 2.           Management's Discussion And Analysis of Financial Condition
                  And Results of Operations

         The following discussion is based primarily on the Consolidated
Financial Statements of CarrAmerica Realty Corporation and its subsidiaries (the
"Company") as of September 30, 1998 and December 31, 1997, and for the three and
nine months ended September 30, 1998 and 1997. The comparability of the periods
is significantly impacted by acquisitions made during 1998 and 1997. As of
September 30, 1997, the Company owned 230 properties.
This number grew to 288 as of September 30, 1998.

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

Results of Operations - Three Months Ended September 30, 1998 and 1997

Operating Revenue. Total operating revenue increased $68.6 million, or 71.1%, to
$165.0 million for the three months ended September 30, 1998 as compared to
$96.4 million for the three months ended September 30, 1997. The increase in
revenue was primarily attributable to a $25.8 million and a $42.8 million
increase in rental revenue and other operating revenue, respectively. The
Company experienced net growth in its rental revenue as a result of its
acquisitions, and development properties placed in service net of dispositions,
which together contributed approximately $23.5 million of additional rental
revenue in the three month period ended September 30, 1998. Rental revenue from
properties that were fully operational throughout both periods increased by
approximately $3.2 million primarily due to increased occupancy and rental rate
increases. Other operating revenue increased by $42.8 million, or 498.6%, for
the three months ended September 30, 1998 to $51.3 million as compared to $8.5
million for the three months ended September 30, 1997, primarily as a result of
the executive office suites revenue related to the Company's acquisitions of
executive suite businesses.

Operating Expenses. Total operating expenses increased $59.2 million for the
three months ended September 30, 1998, or 78.2%, to $135.0 million as compared
to $75.8 million for the three months ended September 30, 1997. The net increase
in operating expenses was attributable to a $8.5 million increase in property
operating expenses, a $5.3 million increase in interest expense, the addition of
$34.4 million in executive office suites operating expenses, a $2.9 million
increase in general and administrative expenses, and an $8.1 million increase in
depreciation and amortization. Property operating expenses increased primarily
as a result of property acquisitions, with property operating expenses from
properties that were fully operational in both periods increasing approximately
$.6 million. The increase in the Company's interest expense is primarily related
to borrowings necessary to fund acquisitions and development commitments. The
addition of executive office suites operating expenses is a result of the
acquisition of executive suite businesses. The increase in general and
administrative expenses is predominately a result of the addition of new staff
to implement the Company's business strategy and the write-off of approximately
$1.1 million of costs associated with abandoned acquisitions. The increase in
depreciation and amortization is predominately a result of depreciation and
amortization on the Company's real estate and executive suite acquisitions.

Other Operating Income. Other operating income increased $8.7 million for the
three months ended September 30, 1998, to $9.5 million as compared to $.8
million for the three months ended September 30, 1997, primarily due to a gain
recognized on the disposition of 189,000 square feet of office space, earnings
from the Company's additional investments in unconsolidated partnerships and the
interest income earned on increased cash balances.

Net Income. Net income of $36.4 million was earned for the three months ended
September 30, 1998 as compared to $18.9 million during the three months ended
September 30, 1997. The comparability of net income between the two periods is
impacted by the acquisitions the Company made and the other changes described
above.


Results of Operations - Nine Months Ended September 30, 1998 and 1997

Operating Revenue. Total operating revenue increased $180.8 million, or 72.8%,
to $429.1 million for the nine months ended September 30, 1998 as compared to
$248.3 million for the nine months ended September 30, 1997. The increase in
revenue was primarily attributable to an $89.1 million and a $91.7 million
increase in rental revenue and other operating revenue, respectively. The
Company experienced net growth in its rental revenue as a result of its
acquisitions, and development properties placed in service net of dispositions,
which together contributed approximately $84.8 million of additional rental
revenue in the nine month period ended September 30, 1998. Rental revenue from
properties that were fully operational throughout both periods increased by
approximately $6.9 million, primarily due to rental rate increases. Other
operating revenue increased by $91.7 million, or 555.0%, for the nine months
ended September 30, 1998 to $108.2 million as compared to $16.5 million for the
nine months ended September 30, 1997, primarily as a result of the executive
office suites revenue earned on the Company's acquisitions of executive suite
businesses.

Operating Expenses. Total operating expenses increased $150.9 million for the
nine months ended September 30, 1998, or 77.9%, to $344.5 million as compared to
$193.6 million for the nine months ended September 30, 1997. The net increase in
operating expenses was attributable to a $25.2 million increase in property
operating expenses, a $16.9 million increase in interest expense, the addition
of $77.9 million in executive office suites operating expenses, a $7.1 million
increase in general and administrative expenses, and a $23.8 million increase in
depreciation and amortization. Property operating expenses increased primarily
as a result of property acquisitions, with property operating expenses from
properties that were fully operational in both periods increasing approximately
$1.3 million. The increase in the Company's interest expense is primarily
related to borrowings necessary to fund acquisitions and development
commitments. The addition of executive office suites operating expenses is a
result of the acquisition of executive suite businesses. The increase in general
and administrative expenses is predominately a result of the addition of new
staff to implement the Company's business strategy and the write-off of
approximately $1.8 million of costs associated with abandoned acquisitions. The
increase in depreciation and amortization is predominately a result of
depreciation and amortization on the Company's real estate and executive suite
acquisitions.

Other Operating Income. Other operating income increased $38.2 million for the
nine months ended September 30, 1998, to $40.5 million as compared to $2.3
million for the nine months ended September 30, 1997, primarily due to the gain
recognized on the disposition of 456,000 square feet of office space, earnings
from the Company's additional investments in unconsolidated partnerships, and
the interest income earned on cash balances.

Net Income. Net income of $111.0 million was earned for the nine months ended
September 30, 1998 as compared to $50.7 million during the nine months ended
September 30, 1997. The comparability of net income between the two periods is
impacted by the acquisitions the Company made and the other changes described
above.

Cash Flows. Net cash provided by operating activities increased $144.9 million,
or 151.1%, to $240.8 million for the nine months ended September 30, 1998 as
compared to $95.9 million for the nine months ended September 30, 1997,
primarily as a result of the acquisitions made and development placed in service
by the Company. Net cash used by investing activities increased $251.9 million,
to $997.2 million for the nine months ended September 30, 1998 as compared to
$745.3 million for the nine months ended September 30, 1997, primarily as a
result of capital deployed by the Company for acquisitions of office properties,
executive suite businesses, land held for future development and investments in
construction in progress. Net cash provided by financing activities increased
$125.0 million, to $772.6 million for the nine months ended September 30, 1998
as compared to $647.6 million for the nine months ended September 30, 1997,
primarily as a result of borrowings on the unsecured credit facility, and
proceeds from sales of common stock and unsecured bonds net of dividends paid to
the common and preferred stockholders.

                    and Results of Operations of the Company
- --------------------------------------------------------------------------------

Liquidity And Capital Resources

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

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

         The Company's total indebtedness at September 30, 1998 was $1.602
billion, of which $547.5 million, or 34.2%, bears a LIBOR-based floating
interest rate. Currently, the unsecured credit facilities bear interest at 90
basis points over LIBOR on the $450 million facility and the $200 million
facility. The Company's mortgages payable fixed rate indebtedness bears an
effective weighted average interest rate of 8.2% at September 30, 1998 and has a
weighted average term to maturity of 4.6 years. Based upon the Company's total
market capitalization at September 30, 1998 of $3.809 billion (the common stock
price was $22.88 per share; the total shares of common stock, convertible
preferred stock and Units outstanding was 78,957,151 and the aggregate
liquidation value of the cumulative redeemable preferred stock was $400
million), the Company's debt represented 42.1% of its total market
capitalization. As of November 13, 1998, the Company had $353.5 million
outstanding under the unsecured credit facilities, leaving $296.5 million for
draw.

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

         Additionally, the Company and it's subsidiaries (including CarrAmerica
Development) will require a substantial amount of capital for development
projects currently underway and planned for the future. As of September 30,
1998, the Company had approximately 5.0 million square feet of office space in
63 development projects underway which is expected to require a total investment
by the Company of approximately $767 million. As of September 30, 1998, the
Company had expended $399 million, or 52.0 percent of the total expected
investment.

         The Company's subsidiaries also have various capital needs.
Specifically, OmniOffices is currently developing approximately 20 executive
office suite centers. The total cost to complete these projects is approximately
$26.8 million, of which approximately $15.5 million was expended as of September
30, 1998. In addition, OmniOffices currently is considering several acquisitions
of existing executive office suite centers, although no binding agreements have
been executed. Future cash needs of OmniOffices are expected to be met by draws
on the OmniOffices line of credit facility. As this subsidiary continues to
grow, the Company may in the future elect to dispose of part or all of its
equity interest in OmniOffices, including through a distribution of stock in
OmniOffices to the Company's stockholders, but no decision with respect to any
such disposition has been made at this time.

                    and Results of Operations of the Company
- --------------------------------------------------------------------------------

         Finally, the Company may need additional capital to satisfy its
obligations under the agreement entered into with Merrill Lynch in connection
with the Company's "forward equity sale" transaction, described in more detail
in note 7 to the Company's Condensed Consolidated Financial Statements above.

         Historically, management has primarily met the Company's capital
requirements by accessing the public equity and debt markets. However, because
of certain unfavorable conditions currently existing in the public equity and
debt markets, the Company does not believe that these markets are currently
providing the Company with the most attractive sources of capital. If conditions
in the public equity or debt markets improve, the Company will evaluate the cost
of capital raised in such markets to determine if it is the most attractive
capital available to the Company at the time. However, there can be no assurance
that conditions will improve in the near term.

         In response to the current conditions in the equity and debt markets,
the Company plans to address its cash needs through utilization of the Company's
line of credit, refinancing select assets, prudent use of joint ventures and the
disposition of certain assets. Currently, the Company has 25 assets under
contract for sale primarily in the Northern California, Dallas and Atlanta
markets. In addition, the Company has 6 properties under letter of intent for
sale. These properties are expected to produce net proceeds of approximately
$188 million. Due to the uncertainties in the disposition process, there can be
no assurances that these sales will close or that they will achieve the expected
net proceeds.

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

         Net cash provided by operating activities was $240.8 million for the
nine months ended September 30, 1998, compared to $95.9 million for the nine
months ended September 30, 1997. The increase in net cash provided by operating
activities was primarily a result of acquisitions made and development placed in
service by the Company. The Company's investing activities used approximately
$997.2 billion and $745.3 million for the nine months ended September 30, 1998
and 1997, respectively. The Company's investment activities included the
acquisitions of office buildings, executive office suites businesses, and land
held for future development and additions to construction in process of
approximately $895.5 million for the nine months ended September 30, 1998, as
compared to $718.5 million in acquisitions during the same period in 1997.
Additionally, the Company invested approximately $42.4 million and $21.6 million
in its existing real estate assets for the nine months ended September 30, 1998
and 1997, respectively. Net of distributions to the Company's stockholders and
minority interests, the Company's financing activities provided net cash of
$900.9 million and $728.5 million for the nine months ended September 30, 1998
and 1997, respectively. For the nine months ended September 30, 1998, the
Company raised $335.9 million through the sale of common stock which was used to
repay amounts outstanding under its unsecured credit facility and to fund
acquisitions. The Company also drew amounts from its unsecured credit facilities
during 1998 to finance its acquisitions and other investing activities. For the
nine months ended September 30, 1998, the Company's net borrowings on its
unsecured credit facility were approximately $388.0 million.

         Rental revenue and real estate service revenue have been the principal
sources of capital to fund the Company's operating expenses, debt service and
capital expenditures, excluding non-recurring capital expenditures. The Company
believes that rental revenue and real estate service revenue will continue to
provide the necessary funds for its operating expenses and debt service.

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

         The Year 2000 issue results from a programming convention in which
computer programs use two digits rather than four to define the applicable year.
Software and hardware may recognize a date using "00" as the year 1900, rather
than the year 2000. Such an inability of computer programs to recognize a year
that begins with "20" could result in business or building system failures,
miscalculations or errors causing disruptions of operations or other business
problems, including, among other things, a temporary inability to process
transactions, send invoices or engage in other normal business activities.

         The Company has undertaken a comprehensive program to address the Year
2000 issue. In the second quarter of 1998, the Company expanded its program and
appointed a Year 2000 Steering Committee to manage centrally its Year 2000
compliance program (known internally as "Project 2000"). The Steering Committee
includes representatives of senior level management representing a wide array of
the organization. The Steering Committee is charged with overseeing the
Company's comprehensive action plan designed to address Year 2000 issues.

         The Company's Steering Committee has engaged the independent consulting
firm of Computer Technology Associates, Inc. ("CTA") to serve as the Project
Manager for Project 2000. The project is organized into two areas of
concentration: (i) Property Operations Embedded Systems and (ii) Internal
Business Operations Technology. The Property Operations segment of the program
focuses primarily on equipment and systems present in the Company's operating
properties that may contain embedded microcontroller technology (such as
elevators and HVAC systems). The Internal Business Operations segment focuses
primarily on the Company's information technology, operating systems (such as
such as billing, accounting and financial reporting systems) and certain systems
of the Company's major vendors and material service providers. As described
below, Project 2000 involves (i) the assessment of the Year 2000 problems that
may affect the Company, (ii) the development of remedies to address the problems
discovered in the assessment phase, (iii) the testing of such remedies and (iv)
the preparation of contingency plans to deal with the potential failure of
important and critical systems.

         Assessment. During the course of its assessment phase, the Company
continues to identify substantially all of the major components of its property
and business operations systems which may be vulnerable to the Year 2000 issue.
In terms of Property Operations, the Company is conducting a comprehensive
inventory of all the buildings' systems and equipment. Systems are ranked (0-3)
based upon each systems' importance to the properties' operations. Those systems
classified as level 2 or 3 (the highest levels of importance) are compared to
CTA's existing embedded systems database to determine the status of Year 2000
compliance if it is not already known by the Company. If relevant information is
not contained in the existing database, the system is then identified for
processing through vendor management coordinated by CTA. Vendor management
involves concentrated communication with the vendor in an attempt to determine
the status of a systems Year 2000 compliance and any available remedies. As of
the third quarter of 1998, inventory of the Company's operating properties was
substantially complete (approximately 98%). Assessment of property operations is
scheduled for completion in the fourth quarter of 1998.

         In terms of Internal Business Operations Technology, team leaders have
been selected from each business unit and market office to assist in identifying
software, hardware and external interfaces which may be vulnerable to Year 2000
issues. Inventory of both core business units and all market offices is expected
to be completed by the end of the fourth quarter of 1998. The Company's primary
billing and accounting software is currently undergoing a routine application
upgrade expected to be complete by the end of the fourth quarter of 1998. The
vendor of the software has received the Information Technology Association of
America (ITAA) 2000 Certification and represents that the system is Year 2000
ready, and the Company expects to test the system during the first quarter of
1999. In addition, during the third quarter of 1998, the Company continued
communicating with other significant hardware, software and other material
services providers, requesting them to provide the Company with detailed,
written information concerning existing or anticipated Year 2000 compliance of
their systems insofar as the systems relate to such parties' business activities
with the Company. The Company expects that it will complete its distribution of
these inquiries by the end of the fourth quarter of 1998.

         Remediation and Testing Phase. Based upon the results of its assessment
efforts, the Company will undertake remediation and testing activities. The
Company intends to complete this phase by the end of the third quarter of 1999.
The activities conducted during the remediation and testing phase are intended
to provide assurance from both the Property Operation and the Internal Business
perspectives that critical and important applications, systems and equipment
will be substantially Year 2000 compliant on a timely basis. In this phase, the
Company will first evaluate applications, systems and equipment. If a potential
Year 2000 problem is identified, the Company will take steps to attempt to
remediate the problem and, where applicable, test to confirm that the
remediating changes are effective and have not adversely affected the
functionality of that application. After the various applications, system
components and equipment have undergone remediation and testing phases, the
Company, where applicable, will conduct integrated testing for the purpose of
demonstrating functional integrated systems operations.

         Contingency Plans. The Company intends to develop contingency plans to
handle its most reasonably likely worst case Year 2000 scenarios, which it is in
the process of identifying. The Company intends to complete its determination of
worst case scenarios after it has received and analyzed responses to
substantially all of the inquiries it has made of third parties. The Company
expects to complete contingency plans by the end of the third quarter of 1999.

         Costs Related to the Year 2000 Issue. To date, the Company, has
incurred approximately $.3 million in costs for its Year 2000 program. The
Company currently estimates that it will incur additional costs, which are not
expected to exceed approximately $4.3 million, to complete its Year 2000
compliance work. Of such additional costs, approximately $1.5 million are
expected to be incurred during 1998 and approximately $2.8 million are expected
to be during 1999. The Company believes that a portion of these costs may be
recoverable from tenants but has not determined at this time the extent to which
such recovery can be realized.

         Risks Related to the Year 2000 Issue. Although the Company's Year 2000
efforts are intended to minimize the adverse effects of the Year 2000 issue on
the Company's business and operations, the actual effects of the Year 2000 issue
and the success or failure of the Company's efforts described above cannot be
known until the year 2000. Failure by the Company and its major vendors, other
material service providers and material clients to address adequately their
respective Year 2000 issues in a timely manner (insofar as such issues relate to
the Company's business) could have a material adverse effect on the Company's
business, results of operations and financial condition.

Other Matters

         Effective March 19, 1998, the Company has adopted the Emerging Issues
Task Force's Issue 97-11, "Accounting for Internal Costs Relating to Real Estate
Property Acquisitions." Issue 97-11 states that internal costs from acquiring
operating property should be expensed as incurred. Costs that have been
capitalized in the Company's financial statements from January 1, 1998 through
March 19, 1998 amounted to $.7 million. The Company believes that this will not
have a material effect on the Company's operations.

Funds From Operations

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

duration of the Interest Period applicable thereto, subject to the provisions of
the definition of Interest Period.

                  (b) Either Borrower or CarrAmerica LP shall give the Lead
Agent, and the designated Fronting Bank, written notice in the event that it
desires to have Letters of Credit (each, a "Letter of Credit") issued hereunder
no later than 10:00 a.m., New York City time, at least four (4) Domestic
Business Days prior to the date of such issuance. Each such notice shall specify
(i) the designated Fronting Bank, (ii) the aggregate amount of the requested

                                       33
<PAGE>

Letters of Credit, (iii) the individual amount of each requested Letter of
Credit and the number of Letters of Credit to be issued, (iv) the date of such
issuance (which shall be a Domestic Business Day), (v) the name and address of
the beneficiary, (vi) the expiration date of the Letter of Credit (which in no
event shall be later than twelve (12) months after the issuance of such Letter
of Credit or the Maturity Date, whichever is earlier), (vii) the purpose and
circumstances for which such Letter of Credit is being issued, (viii) the terms
upon which each such Letter of Credit may be drawn down (which terms shall not
leave any discretion to Fronting Bank), and (ix) whether such Letters of Credit
shall be attributable to Tranche A Loan Amount or Tranche B Loan Amount. Each
such notice may be revoked telephonically by the applicable Borrower or
CarrAmerica LP, as the case may be, to the applicable Fronting Bank and the Lead
Agent any time prior to the date of issuance of the Letter of Credit by the
applicable Fronting Bank, provided such revocation is confirmed in writing by
such Borrower or CarrAmerica LP to the Fronting Bank and the Lead Agent within
one (1) Domestic Business Day by facsimile. No later than 10:00 a.m., New York
City time, on the date that is four (4) Domestic Business Days prior to the date
of issuance, the applicable Borrower or CarrAmerica LP shall specify a precise
description of the documents and the verbatim text of any certificate to be
presented by the beneficiary of such Letter of Credit, which if presented by
such beneficiary prior to the expiration date of the Letter of Credit would
require the Fronting Bank to make a payment under the Letter of Credit; provided
that Fronting Bank may, in its reasonable judgment, require changes in any such
documents and certificates only in conformity with changes in customary and
commercially reasonable practice or law and provided further, that no Letter of
Credit shall require payment against a conforming draft to be made thereunder on
the following Domestic Business Day that such draft is presented if such
presentation is made later than 10:00 A.M. New York City time (except that if
the beneficiary of any Letter of Credit requests at the time of the issuance of
its Letter of Credit that payment be made on the same Domestic Business Day
against a conforming draft, such beneficiary shall be entitled to such a same
day draw, provided such draft is presented to the applicable Fronting Bank no
later than 10:00 A.M. New York City time and provided further that, prior to the
issuance of such Letter of Credit, such Borrower or CarrAmerica LP shall have
requested to Fronting Bank and the Lead Agent that such beneficiary shall be
entitled to a same day draw). In determining whether to pay on such Letter of
Credit, the Fronting Bank shall be responsible only to determine that the
documents and certificates required to be delivered under the Letter of Credit
have been delivered and that they comply on their face with the requirements of
that Letter of Credit.

                  (a) The Money Market Option. In addition to Committed
Borrowings pursuant to Section 2.1 and Section 2.2 hereof, the applicable
Borrower or CarrAmerica LP, as the case may be, may, as set forth in this
Section and provided that at the time Carr shall have two Investment Grade
Ratings (at least one of which shall be from S&P or Moody's), and Borrowers LTV
Ratio shall be less than 55%, request the Banks at any time or from time to time
during the Term to make offers to make Money Market Loans to such Borrower or
CarrAmerica LP, as the case may be, not to exceed $225,000,000 in the aggregate
outstanding at any one time. The Banks may, but shall have no obligation to,
make such offers and the applicable Borrower or CarrAmerica LP, as the case may
be, may, but shall have no obligation to, accept any such offers in the manner
set forth in this Section.

                  (b) Money Market Quote Request. When the applicable Borrower
or CarrAmerica LP, as the case may be, wishes to request offers to make Money
Market Loans under this Section, it shall transmit to the Lead Agent by telex or
facsimile transmission a request for Money Market Quotes substantially in the
form of Exhibit D hereto (a "Money Market Quote Request") so as to be received
not later than 10:30 A.M. (New York City time) on (x) the fourth Euro-Dollar
Business Day prior to the date of Borrowing proposed therein, in the case of a
LIBOR Auction or (y) the Domestic Business Day next preceding the date of
Borrowing proposed therein, in the case of an Absolute Rate Auction (or, in
either case, such other time or date as the Borrowers and the Lead Agent shall
have mutually agreed and shall have notified to the Banks not later than the
date of the Money Market Quote Request for the first LIBOR Auction or Absolute
Rate Auction for which such change is to be effective) specifying:

                  (i) the proposed date of Borrowing, which shall be a
         Euro-Dollar Business Day in the case of a LIBOR Auction or a Domestic
         Business Day in the case of an Absolute Rate Auction,

                  (ii) the aggregate amount of such Borrowing, which shall be
         $10,000,000 or a larger multiple of $500,000,

                                       35
<PAGE>

                  (iii) the duration of the Interest Period applicable thereto,
         subject to the provisions of the definition of Interest Period,

                  (iv) whether the Money Market Quotes requested are to set
         forth a Money Market Margin or a Money Market Absolute Rate,

                  (v) whether the Money Market Loan will consist in full or in
         part of the Tranche A Loan and/or the Tranche B Loan, and if consisting
         in part of each, the portions consisting of Tranche A Loans and Tranche
         B Loans, and

                  (vi) whether a Bank may designate a Designated Lender in
         connection with such Money Market Loan.

The applicable Borrower or CarrAmerica LP, as the case may be, may request
offers to make Money Market Loans for more than one Interest Period in a single
Money Market Quote Request. No Money Market Quote Request shall be given within
five Euro-Dollar Business Days (or such other number of days as the Borrowers
and the Lead Agent may agree) of any other Money Market Quote Request.

                  (c) Invitation for Money Market Quotes. Promptly upon receipt
of a Money Market Quote Request, but no later than 1:00 p.m. (New York City
time) on (i) the fourth Euro-Dollar Business Day prior to the proposed date of
Borrowing, or (ii) the Domestic Business next preceding the date of the proposed
Borrowing, the Lead Agent shall send to the Banks by telex or facsimile
transmission an Invitation for Money Market Quotes substantially in the form of
Exhibit E hereto (an "Invitation for Money Market Quotes"), which shall
constitute an invitation by the applicable Borrower or CarrAmerica LP, as the
case may be, to each Bank to submit Money Market Quotes offering to make the
Money Market Loans to which such Money Market Quote Request relates in
accordance with this Section.

                  (d) Submission and Contents of Money Market Quotes. (i) Each
Bank may submit a Money Market Quote containing an offer or offers to make Money
Market Loans in response to any Invitation for Money Market Quotes. Each Money
Market Quote must comply with the requirements of this subsection (d) and must
be submitted to the Lead Agent by telex or facsimile transmission at its offices
specified in or pursuant to Section 9.1 not later than (x) 10:00 A.M. (New York

                                       36
<PAGE>

the third Euro-Dollar Business Day prior to the proposed date of Borrowing, in
the case of a LIBOR Auction or (y) 10:00 A.M. (New York City time) on the
proposed date of Borrowing, in the case of an Absolute Rate Auction (or, in
either case, such other time or date as the Borrowers and the Lead Agent shall
have mutually agreed and shall have notified to the Banks not later than the
date of the Money Market Quote Request for the first LIBOR Auction or Absolute
Rate Auction for which such change is to be effective); provided that Money
Market Quotes submitted by the Lead Agent (or any affiliate of the Lead Agent)
in its capacity of a Bank may be submitted, and may only be submitted, if the
Lead Agent or such affiliate notifies the applicable Borrower or CarrAmerica LP,
as the case may be, of the terms of the offer or offers contained therein not
later than thirty (30) minutes prior to the applicable deadline for the other
Banks. Subject to Articles III and VI, any Money Market Quote so made shall be
irrevocable except with the written consent of the Lead Agent given on the
instructions of the applicable Borrower or CarrAmerica LP, as the case may be.
If, and only if, the applicable Borrower or CarrAmerica LP, as the case may be,
elected in the applicable Money Market Quote Request to permit the Banks to
designate Designated Lenders to fund such Money Market Loans, such Money Market
Loans may be funded by such Bank's Designated Lender (if any) as provided in
Section 9.6(d), however such Bank shall not be required to specify in its Money
Market Quote whether such Money Market Loans will be funded by such Designated
Lender.

                  (ii) Each Money Market Quote shall be in substantially the
         form of Exhibit F hereto and shall in any case specify:

                  (1) the proposed date of Borrowing,

                  (2) the principal amount of the Money Market Loan for which
         each such offer is being made, which principal amount (w) may be
         greater than or less than the Commitment of the quoting Bank, (x) must
         be $5,000,000 or a larger multiple of $500,000, (y) may not exceed the
         principal amount of Money Market Loans for which offers were requested
         and (z) may be subject to an aggregate limitation as to the principal
         amount of Money Market Loans for which offers being made by such
         quoting Bank may be accepted,

                  (3) in the case of a LIBOR Auction, the margin above or below
         the applicable London Interbank Offered Rate (the "Money Market
         Margin") offered for each such Money Market Loan, expressed as a
         percentage (specified to the nearest 1/10,000th of 1%) to be added to
         or subtracted from the applicable London Interbank Offered Rate,

                                       37
<PAGE>

                  (4) in the case of an Absolute Rate Auction, the rate of
         interest per annum (specified to the nearest 1/10,000th of 1%) (the
         "Money Market Absolute Rate") offered for each such Money Market Loan,
         and

                  (5) the identity of the quoting Bank.

A Money Market Quote may set forth up to five separate offers by the quoting
Bank with respect to each Interest Period specified in the related Invitation
for Money Market Quotes.

                  (iii) Any Money Market Quote shall be disregarded if it:

                  (1) is not substantially in conformity with Exhibit F hereto
         or does not specify all of the information required by subsection
         (d)(ii) above;

                  (2) contains qualifying, conditional or similar language;

                  (3) proposes terms other than or in addition to those set
         forth in the applicable Invitation for Money Market Quotes; or

                  (4) arrives after the time set forth in subsection (d)(i).

                  (e) Notice to Borrower. The Lead Agent shall promptly notify
the applicable Borrower or CarrAmerica LP, as the case may be, (x) with respect
to each Money Market Quote submitted in accordance with subsection (d), of the
terms of such Money Market Quote and the identity of the Bank submitting such
Money Market Quote and (y) of any Money Market Quote that amends, modifies or is
otherwise inconsistent with a previous Money Market Quote submitted by such Bank
with respect to the same Money Market Quote Request. Any such subsequent Money
Market Quote shall be disregarded by the Lead Agent unless such subsequent Money
Market Quote is submitted solely to correct a manifest error in such former
Money Market Quote. The Lead Agent's notice to the applicable Borrower or
CarrAmerica LP, as the case may be, shall specify (A) the aggregate principal
amount of Money Market Loans for which Money Market Quotes have been received
for each Interest Period specified in the related Money Market Quote Request,
(B) the respective principal amounts and Money Market Margins or Money Market
Absolute Rates, as the case may be, so offered and (C) if applicable,
limitations on the aggregate principal amount of Money Market Loans for which
offers in any single Money Market Quote may be accepted.

<PAGE>

                  (f) Acceptance and Notice by Borrower. Not later than 12:00
noon (New York City time) on (x) the third Euro-Dollar Business Day prior to the
proposed date of Borrowing, in the case of a LIBOR Auction or (y) the proposed
date of Borrowing, in the case of an Absolute Rate Auction (or, in either case,
such other time or date as the Borrowers and the Lead Agent shall have mutually
agreed and shall have notified the Banks not later than the date of the Money
Market Quote Request for the first LIBOR Auction or Absolute Rate Auction for
which such change is to be effective), the applicable Borrower, or CarrAmerica
LP, as the case may be, shall notify the Lead Agent of its acceptance or
non-acceptance of the Money Market Quotes specified in the Lead Agent's notice
to the applicable Borrower or CarrAmerica LP, as the case may be, pursuant to
subsection (e). In the case of acceptance, such notice (a "Notice of Money
Market Borrowing") shall specify the aggregate principal amount of offers for
each Interest Period that are accepted and shall specify whether such offer is
to be allocated to Tranche A or Tranche B. The applicable Borrower or
CarrAmerica LP, as the case may be, may accept any Money Market Quote in whole
or in part; provided that:

                      (i) the aggregate principal amount of each Money Market
               Borrowing may not exceed the applicable amount set forth in the
               related Money Market Quote Request;

                      (ii) the principal amount of each Money Market Borrowing
               must be $10,000,000 or a larger multiple of $500,000;

                      (iii) acceptance of offers may only be made on the basis
               of ascending Money Market Margins or Money Market Absolute Rates,
               as the case may be; and

                      (iv) the applicable Borrower or CarrAmerica LP, as the
               case may be, may not accept any Money Market Quote that is
               described in subsection (d)(iii) or that otherwise fails to
               comply with the requirements of this Agreement.

                                       39
<PAGE>

               For the purposes of Section 2.1 hereof, all Money Market Loans
made on the same date of Borrowing for the same Interest Period shall constitute
a single Borrowing.

                  (g) Allocation by Lead Agent. If Money Market Quotes are made
by two or more Banks with the same Money Market Margins or Money Market Absolute
Rates, as the case may be, for a greater aggregate principal amount than the
amount in respect of which such Money Market Quotes are accepted for the related
Interest Period, the principal amount of Money Market Loans in respect of which
such Money Market Quotes are accepted shall be allocated by the Lead Agent among
such Banks as nearly as possible (in multiples of $500,000, as the Lead Agent
may deem appropriate) in proportion to the aggregate principal amounts of such
Money Market Quotes. Determinations by the Lead Agent of the amounts of Money
Market Loans shall be conclusive in the absence of manifest error.

                  (h) Notification by Lead Agent. Upon receipt of a Notice of
Money Market Borrowing in accordance with Section 2.3(f) hereof, the Lead Agent
shall, on the date such Notice of Money Market Borrowing is received by the Lead
Agent, notify each Bank of the principal amount of the Money Market Borrowing
accepted by the applicable Borrower or CarrAmerica LP, as the case may be, and
of such Bank's share (if any) of such Money Market Borrowing and such Notice of
Money Market Borrowing shall not thereafter be revocable by the applicable
Borrower or CarrAmerica LP, as the case may be. Provided that the applicable
Borrower or CarrAmerica LP, as the case may be, elected in the applicable Money
Market Quote Request to permit the Banks to designate Designated Lenders to fund
such Money Market Loans, a Bank who is notified that it has been selected to
make a Money Market Loan may designate its Designated Lender (if any) to fund
such Money Market Loan on its behalf, as described in Section 9.6(d). Any
Designated Lender which funds a Money Market Loan shall on and after the time of
such funding become the obligee under such Money Market Loan and be entitled to
receive payment thereof when due. No Bank shall be relieved of its obligation to
fund a Money Market Loan, and no Designated Lender shall assume such obligation,
prior to the time the applicable Money Market Loan is funded.

               SECTION 2.4. Notice to Banks; Funding of Loans.

                  (a) Upon receipt of a Notice of Committed Borrowing, the Lead
Agent shall notify each Bank on the same day as it receives such Notice of
Committed Borrowing of the contents thereof and of such Bank's share of such
Borrowing and such Notice of Committed Borrowing shall not thereafter be
revocable by the applicable Borrower or CarrAmerica LP.

                  (b) Not later than 2:00 P.M. (New York City time) on the date
of each Committed Borrowing as indicated in the Notice of Committed Borrowing,
each Bank shall (except as provided in subsection (c) of this Section) make
available its share of such Borrowing, in Federal or other funds immediately
available in New York City, to the Lead Agent at its address referred to in
Section 9.1. The Lead Agent will make the funds so received from the Banks
available to the applicable Borrower or CarrAmerica LP, as applicable, at the
Lead Agent's aforesaid address. If a Borrower or CarrAmerica LP has requested
the issuance of a Letter of Credit, no later than 12:00 Noon (New York City
time) on the date of such issuance as indicated in the Notice of Committed
Borrowing, the Fronting Bank shall issue such Letter of Credit in the amount so
requested and deliver the same to the applicable Borrower or CarrAmerica LP with
a copy thereof to the Lead Agent. Immediately upon the issuance of each Letter
of Credit by the Fronting Bank, such Fronting Bank shall be deemed to have sold
and transferred to each other Bank, and each such other Bank shall be deemed to,
and hereby agrees to, have irrevocably and unconditionally purchased and
received from Fronting Bank, without recourse or warranty, an undivided interest
and a participation in such Letter of Credit, any drawing thereunder, and the
obligations of the applicable Borrower or CarrAmerica LP hereunder with respect
thereto, and any security therefor or guaranty pertaining thereto, in an amount
equal to such Bank's ratable share thereof (based upon the ratio its Commitment
bears to the aggregate of all Commitments). Upon any change in any of the
Commitments in accordance herewith, there shall be an automatic adjustment to
such participations to reflect such changed shares. The Fronting Bank shall have
the primary obligation to fund any and all draws made with respect to such
Letter of Credit notwithstanding any failure of a participating Bank to fund its
ratable share of any such draw. The Lead Agent will instruct the Fronting Bank
to make such Letter of Credit available to such Borrower and the Fronting Bank
shall make such Letter of Credit available to the applicable Borrower or
CarrAmerica LP at the applicable Borrower's or CarrAmerica's LP aforesaid
address on the date of the Borrowing.

                                       41
<PAGE>

                  (c) Unless the Lead Agent shall have received notice from a
Bank prior to the date of any Borrowing that such Bank will not make available
to the Lead Agent such Bank's share of such Borrowing, the Lead Agent may assume
that such Bank has made such share available to the Lead Agent on the date of
such Borrowing in accordance with subsection (b) of this Section 2.4 and the
Lead Agent may, in reliance upon such assumption, make available to the
applicable Borrower or CarrAmerica LP, as applicable, on such date a
corresponding amount. If and to the extent that such Bank shall not have so made
such share available to the Lead Agent, such Bank and the applicable Borrower or
CarrAmerica LP severally agree to repay to the Lead Agent forthwith on demand
such corresponding amount together with interest thereon, for each day from the
date such amount is made available to the applicable Borrower or CarrAmerica LP
until the date such amount is repaid to the Lead Agent, at (i) in the case of
either Borrower or CarrAmerica LP, a rate per annum equal to the higher of the
Federal Funds Rate and the interest rate applicable thereto pursuant to Section
2.7 and (ii) in the case of such Bank, the Federal Funds Rate. If such Bank
shall repay to the Lead Agent such corresponding amount, such amount so repaid
shall constitute such Bank's Loan included in such Borrowing for purposes of
this Agreement.

                  SECTION 2.5. Notes.

                  (a) The Tranche A Loans shall be evidenced by the Tranche A
Notes, each of which shall be payable to the order of each Bank for the account
of its Applicable Lending Office in an amount equal to each such Bank's Tranche
A Commitment.

                  (b) The Tranche B Loans shall be evidenced by the Tranche B
Notes, each of which shall be payable to the order of each Bank for the account
of its Applicable Lending Office in an amount equal to each such Bank's Tranche
B Commitment.

                  (c) Each Bank may, by notice to the Borrowers and CarrAmerica
LP and the Lead Agent, request that its Loans of a particular type be evidenced
by a separate Note in an amount equal to the aggregate unpaid principal amount
of such Loans. Each such Note shall be in substantially the form of Exhibit A-1
or Exhibit A-2 hereto, as applicable, with appropriate modifications to reflect
the fact that it evidences solely Loans of the relevant type. Each reference in
this Agreement to the "Note" of such Bank shall be deemed to refer to and
include any or all of such Notes, as the context may require.

                                       42
<PAGE>

                  (d) Upon receipt of each Bank's Note pursuant to Section
3.1(a) or (b), the Lead Agent shall forward such Note to such Bank. Each Bank
shall record the date, amount, type and maturity of each Loan made by it and the
date and amount of each payment of principal made by either Borrower or
CarrAmerica LP with respect thereto, and may, if such Bank so elects in
connection with any transfer or enforcement of its Note, endorse on the schedule
forming a part thereof appropriate notations to evidence the foregoing
information with respect to each such Loan then outstanding; provided that the
failure of any Bank to make any such recordation or endorsement shall not affect
the obligations of the Borrowers hereunder or under the Notes. Each Bank is
hereby irrevocably authorized by the Borrowers and CarrAmerica LP so to endorse
its Note and to attach to and make a part of its Note a continuation of any such
schedule as and when required.

                  (e) There shall be no more than ten (10) Euro-Dollar
Borrowings outstanding at any one time pursuant to this Agreement.

                  SECTION 2.6. Maturity of Loans. The Loans shall mature, and
the principal amount thereof shall be due and payable, on the Maturity Date.

                  SECTION 2.7. Interest Rates.

                  (a) Each Base Rate Loan shall bear interest on the outstanding
principal amount thereof, for each day from the date such Loan is made until it
becomes due, at a rate per annum equal to the sum of the Applicable Margin for
Base Rate Loans for such day plus the Base Rate for such day. Such interest
shall be payable for each Interest Period on the last day thereof.

                  (b) Each Euro-Dollar Loan shall bear interest on the
outstanding principal amount thereof, for each day during the Interest Period
applicable thereto, at a rate per annum equal to the sum of the Applicable
Margin for Euro-Dollar Loans for such day plus the Adjusted London Interbank
Offered Rate applicable to such Interest Period. Such interest shall be payable
for each Interest Period on the last day thereof and, if such Interest Period is
longer than three months, at intervals of three months after the first day
thereof.

                                       43
<PAGE>

                  "Adjusted London Interbank Offered Rate" applicable to any
Interest Period means a rate per annum equal to the quotient obtained (rounded
upward, if necessary, to the next higher 1/100 of 1%) by dividing (i) the
applicable London Interbank Offered Rate by (ii) 1.00 minus the Euro-Dollar
Reserve Percentage.

                  "Euro-Dollar Reserve Percentage" means for any day that
percentage (expressed as a decimal) which is in effect on such day, as
prescribed by the Board of Governors of the Federal Reserve System (or any
successor) for determining the maximum reserve requirement for a member bank of
the Federal Reserve System in New York City with deposits exceeding five billion
dollars in respect of "Eurocurrency liabilities" (or in respect of any other
category of liabilities which includes deposits by reference to which the
interest rate on Euro-Dollar Loans is determined or any category of extensions
of credit or other assets which includes loans by a non-United States office of
any Bank to United States residents). The Adjusted London Interbank Offered Rate
shall be adjusted automatically on and as of the effective date of any change in
the Euro-Dollar Reserve Percentage.

                  "London Interbank Offered Rate" applicable to any Interest
Period means the average (rounded upward, if necessary, to the next higher 1/16
of 1%) of the respective rates per annum at which deposits in dollars are
offered to the Reference Bank in the London interbank market at approximately
11:00 a.m. (London time) two Euro-Dollar Business Days before the first day of
such Interest Period in an amount approximately equal to the principal amount of
the Euro-Dollar Loan of such Reference Bank to which such Interest Period is to
apply and for a period of time comparable to such Interest Period.

                  (c) Subject to Section 8.1, each Money Market LIBOR Loan shall
bear interest on the outstanding principal amount thereof, for the Interest
Period applicable thereto, at a rate per annum equal to the sum of the London
Interbank Offered Rate for such Interest Period (determined in accordance with
Section 2.7(b) as if the related Money Market LIBOR Loan were a Euro-Dollar
Loan) plus (or minus) the Money Market Margin quoted by the Bank making such
Loan in accordance with Section 2.3. Each Money Market Absolute Rate Loan shall
bear interest on the outstanding principal amount thereof, for the Interest
Period applicable thereto, at a rate per annum equal to the Money Market
Absolute Rate quoted by the Bank making such Loan in accordance with Section
2.3. Such interest shall be payable for each Interest Period on the last day
thereof and, if such Interest Period is longer than ninety days, at intervals of
ninety days after the first day thereof.

                  (d) In the event that, and for so long as, any Event of
Default shall have occurred and be continuing, the outstanding principal amount
of the Loans, and, to the extent permitted by law, overdue interest in respect
of all Loans, shall bear interest at the annual rate of the sum of the Prime
Rate and four percent (4%).

                  (e) The Lead Agent shall determine each interest rate
applicable to the Loans (other than Money Market Loans) hereunder. The Lead
Agent shall give prompt notice to the applicable Borrower or CarrAmerica LP and
the Banks of each rate of interest so determined, and its determination thereof
shall be conclusive in the absence of manifest error.

                  (f) The Reference Bank agrees to use its best efforts to
furnish quotations to the Lead Agent as contemplated by this Section. If the
Reference Bank does not furnish a timely quotation, the provisions of Section
8.1 shall apply.

                  SECTION 2.8. Fees.

                  (a) Facility Fee. Effective as of the date hereof, during the
Term, the Borrowers and/or CarrAmerica LP shall pay to the Lead Agent for the
account of the Banks ratably in proportion to their respective Commitments a
facility fee (the "Facility Fee") equal to .20% per annum on the aggregate
Commitments. The Facility Fee shall be payable in arrears on each January 1,
April 1, July 1 and October 1 during the Term.

                  (b) Letter of Credit Fee. During the Term, the Borrowers
and/or CarrAmerica LP shall pay to the Lead Agent, for the account of the Banks
ratably in proportion to their respective interests in undrawn issued Letters of
Credit, a fee (a "Letter of Credit Fee") in an amount, provided that no Event of
Default shall have occurred and be continuing, equal to a rate per annum equal
to the Applicable Margin for Euro-Dollar Loans on the daily average of such
issued and undrawn Letters of Credit, which fee shall be payable, in arrears, on
each January 1, April 1, July 1 and October 1 during the term. From the
occurrence, and during the continuance, of an Event of Default, such fee shall
be increased to be equal to four percent (4%) per annum on the daily average of
such issued and undrawn Letters of Credit.

                  (c) Fronting Bank Fee. The Borrowers and/or CarrAmerica LP
shall pay any Fronting Bank, for its own account, a fee (a "Fronting Bank Fee")
at a rate per annum equal to .15% of the issued and undrawn amount of such
Letter of Credit, which fee shall be in addition to and not in lieu of, the
Letter of Credit Fee. The Fronting Bank Fee shall be payable in arrears on each
January 1, April 1, July 1 and October 1 during the Term.

                  (d) Fees Non-Refundable. All fees set forth in this Section
2.8 shall be deemed to have been earned on the date payment is due in accordance
with the provisions hereof and shall be non-refundable. The obligation of the
Borrowers and CarrAmerica LP to pay such fees in accordance with the provisions
hereof shall be binding upon the Borrowers and CarrAmerica LP and shall inure to
the benefit of the Lead Agent and the Banks regardless of whether any Loans are
actually made.

                  SECTION 2.9. Mandatory Termination. The term (the "Term") of
the Commitments shall terminate and expire on August 26, 2001 (the "Maturity
Date").

                  SECTION 2.10. Mandatory Prepayment.

                  (a) Intentionally Omitted.

                  (b) In the event that an Unencumbered Asset Pool Property is
sold or released from the restrictions of Section 5.14 hereof, in accordance
with this Agreement, the applicable Borrower shall simultaneously with such sale
or release, prepay to the Lead Agent, for the account of the Banks, an amount
equal to the amount required such that the Tranche A Loans or Tranche B Loans,
as applicable, remain in compliance with Sections 5.8(h), (i) or (j), as the
case may be, after such sale or release. Notwithstanding the foregoing, a
simultaneous like-kind exchange under Section 1031 of the Internal Revenue Code
will not be subject to the provisions of this Section 2.10(b) provided that the
exchanged property has qualified as a New Acquisition and any "boot" associated
therewith shall be applied to prepayment of the Tranche A Loans or Tranche B
Loans, as applicable. Sale of a property in violation of this Section 2.10 shall
constitute an Event of Default.

<PAGE>

                  (c) In the event that the Unencumbered Asset Pool Properties
Minimum Debt Service Coverage is not maintained as of the last day of a calendar
quarter, either (i) the Borrowers will add a New Acquisition or a Real Property
Asset to the Unencumbered Asset Pool Properties in accordance with this
Agreement which, on a pro forma basis (i.e. the Unencumbered Asset Pool
Properties Minimum Debt Service Coverage shall be recalculated to include such
New Acquisition or Real Property Asset as though the same had been an
Unencumbered Asset Pool Property for the entire applicable period, with
appropriate pro forma adjustments to Unencumbered Asset Pool Net Operating Cash
Flow) would result in compliance with the Unencumbered Asset Pool Properties
Minimum Debt Service Coverage or (ii) the Borrowers and/or CarrAmerica LP shall
prepay to the Lead Agent, for the account of the Banks, an amount necessary to
cause the Unencumbered Asset Pool Properties Minimum Debt Service Coverage to be
in compliance. Failure by the Borrowers and/or CarrAmerica LP to comply with the
Unencumbered Asset Pool Properties Minimum Debt Service Coverage within 90 days
of the date of such non-compliance shall be an Event of Default.

                  SECTION 2.11. Optional Prepayments.

                  (a) The Borrowers or CarrAmerica LP may, upon at least one
Domestic Business Day's notice to the Lead Agent, prepay to the Lead Agent, for
the account of the Banks, any Base Rate Borrowing in whole at any time, or from
time to time in part in amounts aggregating One Million Dollars ($1,000,000), or
an integral multiple of One Million Dollars ($1,000,000) in excess thereof or,
if less, the outstanding principal balance, by paying the principal amount to be
prepaid together with accrued interest thereon to the date of prepayment. Each
such optional prepayment shall be applied to prepay ratably the Loans of the
several Banks included in such Borrowing. Any notice of prepayment delivered
pursuant to this Section 2.11(a) shall set forth the amount of such prepayment
which is applicable to any Loan made for working capital purposes after such
prepayment is made.

                  (b) Except as provided in Section 8.2, a Borrower or
CarrAmerica LP may not prepay all or any portion of the principal amount of any
Euro-Dollar Loan prior to the maturity thereof unless the applicable Borrower or
CarrAmerica LP shall also pay any applicable expenses pursuant to Section 2.13.
Any such prepayment shall be upon at least three (3) Euro-Dollar Business Days'
notice to the Lead Agent. Any notice of prepayment delivered pursuant to this
Section 2.11(b) shall set forth the amount of such prepayment which is
applicable to any Loan made for working capital purposes after such prepayment
is made. Each such optional prepayment shall be in the amounts set forth in
Section 2.11(a) above and shall be applied to prepay ratably the Loans of the
Banks included.

<PAGE>

                  (c) The Borrower may not prepay any Money Market Loan pursuant
to this Section 2.11 except with the prior consent of the applicable Bank or
Designated Lender, as the case may be.

                  (d) A Borrower or CarrAmerica LP may, upon at least one (1)
Domestic Business Day's notice to the Lead Agent (by 11:00 a.m New York time on
such Domestic Business Day), reimburse the Lead Agent for the benefit of the
Fronting Bank for the amount of any drawing under a Letter of Credit in whole or
in part in any amount.

                  (e) A Borrower or CarrAmerica LP may at any time return any
undrawn Letters of Credit to the Fronting Bank in whole, but not in part, and
the Fronting Bank shall give the Lead Agent and each of the Banks notice of such
return.

                  (f) Either Borrower may at any time and from time to time
cancel all or any part of the Tranche A Commitments or Tranche B Commitments, as
applicable, in amounts aggregating One Million Dollars ($1,000,000), or an
integral multiple of One Million Dollars ($1,000,000) in excess thereof, by the
delivery to the Lead Agent and the Banks of a notice of cancellation upon at
least three (3) Domestic Business Days' notice to Lead Agent and the Banks,
whereupon, in either event, all or such portion of the Tranche A Commitments or
Tranche B Commitments, as applicable, shall terminate as to the Banks, pro rata
on the date set forth in such notice of cancellation, and, if there are any
Loans then outstanding in an aggregate amount which exceeds the aggregate
Tranche A Commitments or Tranche B Commitments, as applicable (after giving
effect to any such reduction), the applicable Borrower shall prepay to the Lead
Agent, for the account of the Banks, as applicable, all or such portion of Loans
outstanding on such date in accordance with the requirements of Sections 2.11(a)
and (b). In no event shall either Borrower be permitted to cancel Commitments
for which a Letter of Credit has been issued and is outstanding unless such
Borrower returns (or causes to be returned) such Letter of Credit to the
Fronting Bank. A Borrower shall be permitted to designate in its notice of
cancellation which Loans, if any, are to be prepaid.

<PAGE>

                  (g) Upon receipt of a notice of prepayment or cancellation or
a return of a Letter of Credit pursuant to this Section, the Lead Agent shall
promptly, and in any event within one (1) Domestic Business Day, notify each
Bank of the contents thereof and of such Bank's ratable share (if any) of such
prepayment or cancellation and such notice shall not thereafter be revocable by
the Borrowers or CarrAmerica LP.

                  (h) Any amounts so prepaid pursuant to this Section 2.11 may
be reborrowed subject to the other terms of this Agreement. In the event either
Borrower elects to cancel all or any portion of the Commitments pursuant to
Section 2.11(e) hereof, such amounts may not be reborrowed.

                  SECTION 2.12. General Provisions as to Payments.

                  (a) The Borrowers and CarrAmerica LP shall make each payment
of principal of, and interest on, the Loans and of fees hereunder, not later
than 12:00 Noon (New York City time) on the date when due, in Federal or other
funds immediately available in New York City, to the Lead Agent at its address
referred to in Section 9.1. The Lead Agent will distribute to each Bank its
ratable share of each such payment received by the Lead Agent for the account of
the Banks on the same day as received by the Lead Agent if received by the Lead
Agent by 3:00 p.m. (New York City time), or, if received by the Lead Agent after
3:00 p.m. (New York City time), on the immediately following Domestic Business
Day. Whenever any payment of principal of, or interest on, the Base Rate Loans
or of fees shall be due on a day which is not a Domestic Business Day, the date
for payment thereof shall be extended to the next succeeding Domestic Business
Day. Whenever any payment of principal of, or interest on, the Euro-Dollar Loans
shall be due on a day which is not a Euro-Dollar Business Day, the date for
payment thereof shall be extended to the next succeeding Euro-Dollar Business
Day unless such Euro-Dollar Business Day falls in another calendar month, in
which case the date for payment thereof shall be the next preceding Euro-Dollar
Business Day. Whenever any payment of principal of, or interest on, the Money
Market Loans shall be due on a day which is not a Euro-Dollar Business Day, the
date for payment thereof shall be extended to the next succeeding Euro-Dollar
Business Day. If the date for any payment of principal is extended by operation
of law or otherwise, interest thereon shall be payable for such extended time.

<PAGE>

                  (b) Unless the Lead Agent shall have received notice from a
Borrower or CarrAmerica LP prior to the date on which any payment is due to the
Banks hereunder that such Borrower or CarrAmerica LP will not make such payment
in full, the Lead Agent may assume that such Borrower or CarrAmerica LP, as
applicable has made such payment in full to the Lead Agent on such date and the
Lead Agent may, in reliance upon such assumption, cause to be distributed to
each Bank on such due date an amount equal to the amount then due such Bank. If
and to the extent that such Borrower or CarrAmerica LP shall not have so made
such payment, each Bank shall repay to the Lead Agent forthwith on demand such
amount distributed to such Bank together with interest thereon, for each day
from the date such amount is distributed to such Bank until the date such Bank
repays such amount to the Lead Agent, at the Federal Funds Rate.

                  SECTION 2.13. Funding Losses. If a Borrower or CarrAmerica LP
makes any payment of principal with respect to any Euro-Dollar Loan (pursuant to
Article II, VI or VIII or otherwise) on any day other than the last day of the
Interest Period applicable thereto, or the last day of an applicable period
fixed pursuant to Section 2.7(b), or if a Borrower fails to borrow any
Euro-Dollar Loans, after notice has been given to any Bank in accordance with
Section 2.4(a), such Borrower or CarrAmerica LP shall reimburse each Bank within
15 days after demand for any resulting loss or expense incurred by it (or by an
existing Participant in the related Loan), including (without limitation) any
loss incurred in obtaining, liquidating or employing deposits from third
parties, but excluding loss of margin for the period after any such payment or
failure to borrow, provided that such Bank shall have delivered to such Borrower
or CarrAmerica LP a certificate as to the amount of such loss or expense and the
calculation thereof, which certificate shall be conclusive in the absence of
manifest error.

                  SECTION 2.14. Computation of Interest and Fees. Interest based
on the Prime Rate hereunder shall be computed on the basis of a year of 365 days
(or 366 days in a leap year) and paid for the actual number of days elapsed
(including the first day but excluding the last day). All other interest and
fees shall be computed on the basis of a year of 360 days and paid for the
actual number of days elapsed (including the first day but excluding the last
day).

                    SECTION 2.15. Method of Electing Interest Rates.

                    (a) The Loans included in each Borrowing shall bear interest
initially at the type of rate specified by such Borrower or CarrAmerica LP in
the applicable Notice of Borrowing. Thereafter, such Borrower or CarrAmerica LP,
as applicable, may from time to time elect to change or continue the type of
interest rate borne by each Group of Loans (subject in each case to the
provisions of Article VIII), as follows:

                      (i) if such Loans are Base Rate Loans, a Borrower or
CarrAmerica LP, as applicable, may elect to convert such Loans to Euro-Dollar
Loans as of any Euro-Dollar Business Day;

                      (ii) if such Loans are Euro-Dollar Loans, a Borrower or
CarrAmerica LP, as applicable, may elect to convert such Loans to Base Rate
Loans or elect to continue such Loans as Euro-Dollar Loans for an additional
Interest Period, in each case effective on the last day of the then current
Interest Period applicable to such Loans.

Each such election shall be made by delivering a notice (a "Notice of Interest
Rate Election") to the Lead Agent at least three (3) Euro-Dollar Business Days
before the conversion or continuation selected in such notice is to be effective
(unless the relevant Loans are to be continued as Base Rate Loans, in which case
such notice shall be delivered to the Lead Agent no later than 12:00 Noon (New
York City time) at least one (1) Domestic Business Day before such continuation
is to be effective). A Notice of Interest Rate Election may, if it so specifies,
apply to only a portion of the aggregate principal amount of the relevant Group
of Loans; provided that (i) such portion is allocated ratably among the Loans
comprising such Group, (ii) the portion to which such notice applies, and the
remaining portion to which it does not apply, are each $1,000,000 or any larger
multiple of $1,000,000, (iii) subject to Section 2.1, there shall be no more
than ten (10) Borrowings comprised of Euro-Dollar Loans outstanding at any time
under this Agreement, (iv) no Loan may be continued as, or converted into, a
Euro-Dollar Loan when any Event of Default has occurred and is continuing, and
(v) no Interest Period shall extend beyond the Maturity Date.

                  (b) Each Notice of Interest Rate Election shall specify:

                      (i) the Group of Loans (or portion thereof) to which such
notice applies;

                                       51
<PAGE>

                      (ii) the date on which the conversion or continuation
selected in such notice is to be effective, which shall comply with the
applicable clause of subsection (a) above;

                      (iii) if the Loans comprising such Group are to be
converted, the new type of Loans and, if such new Loans are Euro-Dollar Loans,
the duration of the initial Interest Period applicable thereto; and

                      (iv) if such Loans are to be continued as Euro-Dollar
Loans for an additional Interest Period, the duration of such additional
Interest Period.

Each Interest Period specified in a Notice of Interest Rate Election shall
comply with the provisions of the definition of Interest Period.

                  (c) Upon receipt of a Notice of Interest Rate Election from a
Borrower or CarrAmerica LP pursuant to subsection (a) above, the Lead Agent
shall notify each Bank on the same day as it receives such Notice of Interest
Rate Election of the contents thereof and such notice shall not thereafter be
revocable by such Borrower or CarrAmerica LP. If such Borrower or CarrAmerica LP
fails to deliver a timely Notice of Interest Rate Election to the Lead Agent for
any Group of Euro-Dollar Loans, such Loans shall be converted into Base Rate
Loans on the last day of the then current Interest Period applicable thereto.

                  SECTION 2.16. Letters of Credit. (a) Subject to the terms
contained in this Agreement and the other Loan Documents, upon the receipt of a
notice in accordance with Section 2.2(b) requesting the issuance of a Letter of
Credit, the Fronting Bank shall issue a Letter of Credit or Letters of Credit in
such form as is reasonably acceptable to the applicable Borrower or CarrAmerica
LP, as applicable, in an amount or amounts equal to the amount or amounts
requested by the applicable Borrower or CarrAmerica LP.

                  (b) Each Letter of Credit shall be issued in the minimum
amount of One Million Dollars ($1,000,000).

                  (c) The Letter of Credit Usage shall be no more than
$30,000,000 at any one time.

                                       52
<PAGE>

                  (d) There shall be no more than five (5) Letters of Credit
outstanding at any one time.

                  (e) In the event of any request for a drawing under any Letter
of Credit by the beneficiary thereunder, the Fronting Bank shall notify the
applicable Borrower and the Lead Agent (and the Lead Agent shall endeavor to
notify each Bank thereof) on or before the date on which the Fronting Bank
intends to honor such drawing, and, except as provided in this subsection (e),
the applicable Borrower shall reimburse the Fronting Bank, in immediately
available funds, on the same day on which such drawing is honored in an amount
equal to the amount of such drawing. Notwithstanding anything contained herein
to the contrary, however, unless such Borrower or CarrAmerica LP shall have
notified the Lead Agent, and the Fronting Bank prior to 11:00 a.m. (New York
time) on the Domestic Business Day immediately prior to the date of such drawing
that such Borrower intends to reimburse the Fronting Bank for the amount of such
drawing with funds other than the proceeds of the Loans, the applicable Borrower
or CarrAmerica LP shall be deemed to have timely given a Notice of Borrowing
pursuant to Section 2.2 to the Lead Agent, requesting a Borrowing of Base Rate
Loans on the date on which such drawing is honored and in an amount equal to the
amount of such drawing. Each Bank (other than the Fronting Bank) shall, in
accordance with Section 2.4(b), make available its share of such Borrowing to
the Lead Agent, the proceeds of which shall be applied directly by the Lead
Agent to reimburse the Fronting Bank for the amount of such draw. In the event
that any such Bank fails to make available to the Fronting Bank the amount of
such Bank's participation on the date of a drawing, the Fronting Bank shall be
entitled to recover such amount on demand from such Bank together with interest
at the Federal Funds Rate commencing on the date such drawing is honored.

                  (f) If, after the date hereof, any change in any law or
regulation or in the interpretation thereof by any court or administrative or
governmental authority charged with the administration thereof shall either (a)
impose, modify or deem applicable any reserve, special deposit or similar
requirement against letters of credit issued by, or assets held by, or deposits
in or for the account of, or participations in any letter of credit, upon any
Bank (including the Fronting Bank) or (b) impose on any Bank any other condition
regarding this Agreement or such Bank (including the Fronting Bank) as it
pertains to the Letters of Credit or any participation therein and the result of
any event referred to in the preceding clause (a) or (b) shall be to increase


                                       53
<PAGE>

the cost to the Fronting Bank or any Bank of issuing or maintaining any Letter
of Credit or participating therein then the applicable Borrower or CarrAmerica
LP shall pay to the Fronting Bank or such Bank, within 15 days after written
demand by such Bank (with a copy to the Lead Agent), which demand shall be
accompanied by a certificate showing, in reasonable detail, the calculation of
such amount or amounts, such additional amounts as shall be required to
compensate the Fronting Bank or such Bank for such increased costs or reduction
in amounts received or receivable hereunder together with interest thereon at
the Base Rate. The amount specified in the written demand shall, absent manifest
error, be final and conclusive and binding upon the Borrowers and CarrAmerica
LP.

                  (g) The Borrowers and CarrAmerica LP hereby agree to protect,
indemnify, pay and save the Fronting Bank harmless from and against any and all
claims, demands, liabilities, damages, losses, costs, charges and expenses
(including reasonable attorneys' fees and disbursements) which the Fronting Bank
may incur or be subject to as a result of (i) the issuance of the Letters of
Credit, other than as a result of the gross negligence or wilful misconduct of
the Fronting Bank or (ii) the failure of the Fronting Bank to honor a drawing
under any Letter of Credit as a result of any act or omission, whether rightful
or wrongful, of any present or future de jure or de facto government or
governmental authority (collectively, "Governmental Acts"), other than as a
result of the gross negligence or wilful misconduct of the Fronting Bank. As
between the Borrowers, CarrAmerica LP and the Fronting Bank, the Borrowers and
CarrAmerica LP assume all risks of the acts and omissions of, or misuses of, the
Letters of Credit issued by the Fronting Bank, by the beneficiaries of such
Letters of Credit. In furtherance and not in limitation of the foregoing, the
Fronting Bank shall not be responsible (i) for the form, validity, sufficiency,
accuracy, genuineness or legal effect of any document submitted by any party in
connection with the application for and issuance of such Letters of Credit, even
if it should in fact prove to be in any and all respects invalid, insufficient,
inaccurate, fraudulent or forged; (ii) for the validity or insufficiency of any
instrument transferring or assigning or purporting to transfer or assign any
such Letter of Credit or the rights or benefits thereunder or proceeds thereof,
in whole or in part, which may prove to be invalid or ineffective for any
reason; (iii) for failure of the beneficiary of any such Letter of Credit to
comply fully with conditions required in order to draw upon such Letter of
Credit; (iv) for errors, omissions, interruptions or delays in transmission or
delivery of any message, by mail, cable, telegraph, telex, facsimile
transmission, or otherwise; (v) for errors in interpretation of any technical
terms; (vi) for any loss or delay in the transmission or otherwise of any


                                       54
<PAGE>

documents required in order to make a drawing under any such Letter of Credit or
of the proceeds thereof; (vii) for the misapplication by the beneficiary of any
such Letter of Credit of the proceeds of such Letter of Credit; and (viii) for
any consequence arising from causes beyond the control of the Fronting Bank,
including any Government Acts, in each case other than as a result of the gross
negligence or willful misconduct of the Fronting Bank. None of the above shall
affect, impair or prevent the vesting of the Fronting Bank's rights and powers
hereunder. In furtherance and extension and not in limitation of the specific
provisions hereinabove set forth, any action taken or omitted by the Fronting
Bank under or in connection with the Letters of Credit issued by it or the
related certificates, if taken or omitted in good faith, shall not put the
Fronting Bank under any resulting liability to the Borrowers or CarrAmerica LP.

                  (h) If the Fronting Bank or the Lead Agent is required at any
time, pursuant to any bankruptcy, insolvency, liquidation or reorganization law
or otherwise, to return to the Borrowers or CarrAmerica LP any reimbursement by
the Borrowers or CarrAmerica LP of any drawing under any Letter of Credit, each
Bank shall pay to the Fronting Bank or the Lead Agent, as the case may be, its
share of such payment, but without interest thereon unless the Fronting Bank or
the Lead Agent is required to pay interest on such amounts to the person
recovering such payment, in which case with interest thereon, computed at the
same rate, and on the same basis, as the interest that the Fronting Bank or the
Lead Agent is required to pay.

                  SECTION 2.17. Letter of Credit Usage Absolute. The obligations
of the Borrowers and CarrAmerica LP under this Agreement in respect of any
Letter of Credit shall be unconditional and irrevocable, and shall be paid
strictly in accordance with the terms of this Agreement (as the same may be
amended from time to time) and any Letter of Credit Documents (as hereinafter
defined) under all circumstances, including, without limitation, to the extent
permitted by law, the following circumstances:

                  (a) any lack of validity or enforceability of any Letter of
Credit or any other agreement or instrument relating thereto (collectively, the
"Letter of Credit Documents") or any Loan Document;

                  (b) any change in the time, manner or place of payment of, or
in any other term of, all or any of the obligations of either Borrower or
CarrAmerica LP in respect of the Letters of Credit or any other amendment or
waiver of or any consent by either Borrower or CarrAmerica LP to departure from
all or any of the Letter of Credit Documents or any Loan Document, provided that
the Fronting Bank shall not consent to any such change or amendment unless

                         REPRESENTATIONS AND WARRANTIES

which may become a party to this Agreement to make the Loans, the applicable
Borrower or CarrAmerica LP makes the following representations and warranties

Documents and the making of the Loans.

                  SECTION 4.1. Existence and Power of Carr. Carr is duly
organized, validly existing and in good standing as a corporation under the laws
of the State of Maryland and has all powers and all material governmental
licenses, authorizations, consents and approvals required to own its property

LP. Carr LP and CarrAmerica LP are each duly organized, validly existing and in
good standing as a limited partner ship under the laws of the State of Delaware

business as now conducted or as it presently proposes to conduct and each has
been duly qualified and is in good standing in every jurisdiction in which the

Adverse Effect.

                  SECTION 4.3. Power and Authority of Carr. Carr has the
corporate power and authority to execute, deliver and carry out the terms and
provisions of each of the Loan Documents to which it is a party and has taken
all necessary action to authorize the execution and delivery on behalf of Carr

delivered each Loan Document to which it is a party, and each such Loan Document
constitutes the legal, valid and binding obligation of Carr, enforceable in
accordance with its terms, except as enforce ability may be limited by
applicable insolvency, bankruptcy or other laws affecting creditors rights
generally, or general principles of equity, whether such enforceability is
considered in a proceeding in equity or at law.

                                       61
<PAGE>

                  SECTION 4.4. Power and Authority of Carr LP and CarrAmerica
LP. Carr LP and CarrAmerica LP each have the partner ship power and authority to
execute, deliver and carry out the terms and provisions of each of the Loan
Documents to which it is a party and has taken all necessary action to authorize
the execution and delivery on behalf of Carr LP or CarrAmerica LP, as
applicable, and the performance by Carr LP or CarrAmerica LP, as applicable, of
such Loan Documents. Carr LP and CarrAmerica LP have each duly executed and
delivered each Loan Document to which it is a party, and each such Loan Document
constitutes the legal, valid and binding obligation of Carr LP or CarrAmerica
LP, as applicable, enforceable in accordance with its terms, except as
enforceability may be limited by applicable insolvency, bankruptcy or other laws
affecting creditors rights generally, or general principles of equity, whether
such enforceability is considered in a proceeding in equity or at law.

                  SECTION 4.5. No Violation. Neither the execution, delivery
or performance by or on behalf of the Borrowers or CarrAmerica LP of the Loan
Documents, nor compliance by the Borrowers or CarrAmerica LP with the terms and
provisions thereof nor the consummation of the transactions contemplated by the
Loan Documents, (i) will contravene any applicable provision of any law,
statute, rule, regulation, order, writ, injunction or decree of any court or
governmental instrumentality or (ii) will conflict with or result in any breach
of, any of the terms, covenants, conditions or provisions of, or constitute a
default under, or result in the creation or imposition of (or the obligation to
create or impose) any Lien upon any of the property or assets of the Borrowers
or CarrAmerica LP pursuant to the terms of any indenture, mortgage, deed of
trust, or other agreement or other instrument to which the Borrowers or
CarrAmerica LP (or of any partnership of which either Borrower is a partner) is
a party or by which it or any of its property or assets is bound or to which it
is subject or (iii) will cause a default by either Borrower or CarrAmerica LP
under any organizational document of any Subsidiary, or cause a default under

                  (a) The unaudited consolidated balance sheet of Carr as of
June 30, 1998, a copy of which has been delivered to the Lead Agent, fairly
presents, in conformity with generally accepted accounting principles, the
consolidated financial position of Carr as of such date.

                                       62
<PAGE>

                  (b) Since June 30, 1998, (i) there has been no material ad
verse change in the business, financial position or results of operations of the
Borrowers and (ii) except as previously disclosed to the Lead Agent or as
publicly disclosed, neither the Borrowers nor CarrAmerica LP have incurred any
material indebtedness or guaranty.

                  SECTION 4.7. Litigation.

                  (a) There is no action, suit or proceeding pending against, or
to the knowledge of the Borrowers or CarrAmerica LP, threatened against or
affecting, (i) the Borrowers or CarrAmerica LP or any of their Subsidiaries,
(ii) the Loan Documents or any of the transactions contemplated by the Loan
Documents or (iii) any of their assets, in any case before any court or
arbitrator or any governmental body, agency or official in which there is a
reason able likelihood of an adverse decision which could, individually or in
the aggregate, have a Material Adverse Effect or which in any manner draws into
question the validity of this Agreement or the other Loan Documents.

                  (b) There are no final nonappealable judgments or decrees in
an aggregate amount of Five Million Dollars ($5,000,000) or more entered by a
court or courts of competent jurisdiction against the Borrowers or either
Borrower or CarrAmerica LP (other than any judgment as to which, and only to the
extent, a reputable insurance company has acknowledged coverage of such claim in
writing).

                  SECTION 4.8. Compliance with ERISA.

                  (a) Except as previously disclosed to the Lead Agent in
writing, each member of the ERISA Group has fulfilled its obligations under the
minimum funding standards of ERISA and the Internal Revenue Code with respect to
each Plan and is in compliance in all material respects with the presently
applicable provisions of ERISA and the Internal Revenue Code with respect to
each Plan, except where failure to do so would not result in a Material Adverse
Effect. No member of the ERISA Group has (i) sought a waiver of the minimum
funding standard under Section 412 of the Internal Revenue Code in respect of
any Plan, (ii) failed to make any contribution or payment to any Plan or
Multiemployer Plan or in respect of any Benefit Arrangement, or made any
amendment to any Plan or Benefit Arrangement, which has resulted or could result
in the imposition of a Lien or the posting of a bond or other security under
ERISA or the Internal Revenue Code or (iii) incurred any liability under Title
IV of ERISA other than a liability to the PBGC for premiums under Section 4007
of ERISA.

                                       63
<PAGE>

                  (b) The transactions contemplated by the Loan Documents will
not constitute a nonexempt prohibited transaction (as such term is defined in
Section 4975 of the Code or Section 406 of ERISA) that could subject the Lead
Agent or the Banks to any tax or penalty or prohibited transactions imposed
under Section 4975 of the Code or Section 502(i) of ERISA.

                  SECTION 4.9. Environmental Matters. In the ordinary course of
its business, the Borrowers and CarrAmerica LP each review the effect of
Environmental Laws on the business, operations and properties of the Borrowers
and their subsidiaries or CarrAmerica LP, as applicable, in the course of which
they identify and evaluate associated liabilities and costs (including, with
out limitation, any capital or operating expenditures required for clean-up or
closure of properties presently or previously owned, any capital or operating
expenditures required to achieve or maintain compliance with environmental
protection standards imposed by law or as a condition of any license, permit or
contract, any related constraints on operating activities, including any
periodic or permanent shutdown of any facility or reduction in the level of or
change in the nature of operations conducted thereat, any costs or liabilities
in connection with off-site disposal of wastes or Hazardous Substances, and any
actual or potential liabilities to third parties, including employees, and any
related costs and expenses). On the basis of this review, the Borrowers and
CarrAmerica LP have reasonably concluded that such associated liabilities and
costs, including the costs of compliance with Environmental Laws, are unlikely
to have a Material Adverse Effect.

                  SECTION 4.10. Taxes. The initial tax year of each Borrower
for federal income tax purposes was 1993. The initial tax year of CarrAmerica LP
for federal income tax purposes was 1996. The Borrowers and their subsidiaries
and CarrAmerica LP have filed all United States Federal income tax returns and
all other material tax returns which are required to be filed by them and have
paid all taxes due pursuant to such returns or pursuant to any assessment
received by the Borrowers or any subsidiary. The charges, accruals and reserves
on the books of the Borrowers and their subsidiaries and CarrAmerica LP in
respect of taxes or other governmental charges are, in the opinion of the
Borrowers and CarrAmerica LP, adequate.

                                       64
<PAGE>

                  SECTION 4.11. Full Disclosure. All information heretofore
furnished by the Borrowers or CarrAmerica LP to the Lead Agent or any Bank for
purposes of or in connection with this Agreement or any transaction contemplated
hereby is true and accurate in all material respects on the date as of which
such information is stated or certified. The Borrowers and CarrAmerica LP have
disclosed to the Banks in writing any and all facts known to the Borrowers or
CarrAmerica LP which materially and adversely affect or are likely to materially
and adversely affect (to the extent the Borrowers or CarrAmerica LP can now
reasonably foresee), the business, operations or financial condition of the
Borrowers and CarrAmerica LP considered as one enterprise or the ability of the
Borrowers or CarrAmerica LP, as applicable, to perform their obligations under
this Agreement or the other Loan Documents.

                  SECTION 4.12. Solvency. On the Closing Date and after giving
effect to the transactions contemplated by the Loan Documents occurring on the
Closing Date, each Borrower and CarrAmerica LP is Solvent.

                  SECTION 4.13. Use of Proceeds; Margin Regulations. All
proceeds of the Loans will be used by the Borrowers only in accordance with the
provisions hereof. No part of the proceeds of any Loan will be used by the
Borrowers to purchase or carry any Margin Stock or to extend credit to others
for the purpose of purchasing or carrying any Margin Stock. Neither the making
of any Loan nor the use of the proceeds thereof will violate or be inconsistent
with the provisions of Regulations T, U or X of the Federal Re serve Board.

                  SECTION 4.14. Governmental Approvals. No order, consent,
approval, license, authorization, or validation of, or filing, re cording or
registration with, or exemption by, any governmental or public body or
authority, or any subdivision thereof, is required to authorize, or is required
in connection with the execution, delivery and performance of any Loan Document
or the consummation of any of the transactions contemplated thereby other than
those that have already been duly made or obtained and remain in full force and
effect.

                  SECTION 4.15. Investment Company Act; Public Utility Holding
Company Act. Neither Borrower nor CarrAmerica LP is (x) an "investment company"
or a company "controlled" by an "investment company", within the meaning of the
Investment Company Act of 1940, as amended, (y) a "holding company" or a
"subsidiary company" of a "holding company" or an "affiliate" of either a
"holding company" or a "subsidiary company" within the meaning of the Public
Utility Holding Company Act of 1935, as amended, or (z) subject to any other
federal or state law or regulation which purports to restrict or regulate its
ability to borrow money.

                                       65
<PAGE>

                  SECTION 4.16. Closing Date Transactions. On the Closing Date
and immediately prior to the making of the Loans, the trans actions (other than
the making of the Loans) intended to be consummated on the Closing Date will
have been consummated in accordance with all applicable laws. All consents and
approvals of, and filings and registrations with, and all other actions by, any
Person required in order to make or consummate such transactions have been
obtained, given, filed or taken and are in full force and effect.

                  SECTION 4.17. Representations and Warranties in Loan
Documents. All representations and warranties made by the Borrowers and
CarrAmerica LP in the Loan Documents are true and correct in all material
respects.

                  SECTION 4.18. Patents, Trademarks, etc. Each Borrower and
CarrAmerica LP has obtained and holds in full force and effect all patents,
trademarks, service marks, trade names, copyrights and other such rights, free
from burdensome restrictions, which are necessary for the operation of its
business as presently conducted, the impairment of which is likely to have a
Material Adverse Effect. To the Borrowers' and CarrAmerica LP's knowledge, no
material product, process, method, substance, part or other material presently
sold by or employed by the Borrowers or CarrAmerica LP in connection with such
business infringes any patent, trademark, service mark, trade name, copyright,
license or other such right owned by any other Person. There is not pending or,
to the Borrowers' and CarrAmerica LP's knowledge, threatened any claim or
litigation against or affecting either Borrower or CarrAmerica LP contesting its
right to sell or use any such product, process, method, substance, part or other
material.

                  SECTION 4.19. No Default. No Default or Event of Default
exists under or with respect to any Loan Document. Neither Borrower nor
CarrAmerica LP is in default in any material respect beyond any applicable grace
period under or with respect to any other material agreement, instrument or
undertaking to which it is a party or by which it or any of its property is
bound in any respect, the existence of which default is likely (to the extent
that the Borrowers or CarrAmerica LP, as applicable, can now reasonably foresee)
to result in a Material Adverse Effect.

                                       66
<PAGE>

                  SECTION 4.20. Licenses, etc. Each Borrower and CarrAmerica LP
has obtained and holds in full force and effect, all franchises, licenses,
permits, certificates, authorizations, qualifications, accreditations,
easements, rights of way and other consents and approvals which are necessary
for the operation of its businesses as presently conducted, the absence of which
is likely (to the extent that the Borrowers or CarrAmerica LP, as applicable,
can now reasonably foresee) to have a Material Adverse Effect.

                  SECTION 4.21. Compliance With Law. Each Borrower and
CarrAmerica LP is in compliance with all laws, rules, regulations, orders,
judgments, writs and decrees, including, without limitation, all building and
zoning ordinances and codes, the failure to comply with which is likely (to the
extent that the Borrowers or CarrAmerica LP, as applicable, can now reasonably
foresee) to have a Material Adverse Effect.

                  SECTION 4.22. No Burdensome Restrictions. Neither Borrower
nor CarrAmerica LP is a party to any agreement or instrument or subject to any
other obligation or any charter or corporate or partnership restriction, as the
case may be, which, individually or in the aggregate, is likely (to the extent
that the Borrowers or CarrAmerica LP, as applicable, can now reasonably foresee)
to have a Material Adverse Effect.

                  SECTION 4.23. Brokers' Fees. Neither Borrower nor CarrAmerica
LP has dealt with any broker or finder with respect to the transactions
contemplated by the Loan Documents (except with respect to the acquisition or
disposition of Real Property Assets) or otherwise in connection with this
Agreement, and neither Borrower nor CarrAmerica LP has done any acts, had any
negotiations or conversation, or made any agreements or promises which will in
any way create or give rise to any obligation or liability for the payment by
the Borrower or CarrAmerica LP of any brokerage fee, charge, commission or other
compensation to any party with respect to the transactions contemplated by the
Loan Documents (except with respect to the acquisition or disposition of Real
Property Assets), other than the fees payable hereunder.

                  SECTION 4.24. Labor Matters. There are no collective bar
gaining agreements or Multiemployer Plans covering the employees of the
Borrowers or CarrAmerica LP and the Borrowers or CarrAmerica LP have not
suffered any strikes, walkouts, work stop pages or other material labor
difficulty within the last five (5) years.

CarrAmerica LP has conducted a comprehensive review and assesment of its

on that review and inquiry, neither Borrower nor CarrAmerica LP believes that
the year 2000 problem will result in a material adverse change in its business
condition (financial or otherwise), operations, properties or prospects, or
ability to repay the Loans.

immediately due and payable, with all additional interest from time to time
accrued thereon and without presentation, demand, or protest or other
requirements of any kind (including, without limitation, valuation and
appraisement, diligence, presentment, notice of intent to demand or accelerate
and notice of acceleration), all of which are hereby expressly waived by the
Borrowers and CarrAmerica LP; and upon the occurrence and during the continuance
of any other Event of Default, the Lead Agent may exercise any of its rights and
remedies hereunder and by written notice to the Borrowers, declare the unpaid
principal amount of and any and all accrued and unpaid interest on the Loans and
any and all accrued fees and other Obligations hereunder to be, and the same

or disapprove of the acceleration of the Obligations due hereunder or the
exercise of such other remedy recommended by Lead Agent within five (5) Domestic
Business Days after receipt of such notice. If any Bank shall not respond within
such five (5) Domestic Business Day period, then such Bank shall be deemed to

                  (e) Each Borrower and CarrAmerica LP agrees that it will not
(i) sell or otherwise dispose of any interest in the Letter of Credit Collateral
or (ii) create or permit to exist any lien, security interest or other charge or
encumbrance upon or with respect to any of the Letter of Credit Collateral,
except for the security interest created by this Section 6.4.

                  (f) If any Event of Default shall have occurred and be
continuing:

                           (i) The Lead Agent may, in its sole discretion,
without notice to the Borrowers or CarrAmerica LP except as required by law and
at any time from time to time, charge, set off or other wise apply all or any
part of first, (x) amounts previously drawn on any Letter of Credit that have
not been reimbursed by the Borrowers or CarrAmerica LP and (y) any Letter of
Credit Usage described in clause (ii) of the definition thereof that are then

reasonable care in the custody and preservation of the Letter of Credit
Collateral if the Letter of Credit Collateral is accorded treatment
substantially equal to that which the Lead Agent accords its own property, it
being understood that, assuming such treatment, the Lead Agent shall not have
any responsibility or liability with respect thereto.

                  (h) At such time as all Events of Default have been cured or
waived in writing, all amounts remaining in the Letter of Credit Collateral
Account shall be promptly returned to the Borrowers. Absent such cure or written
waiver, any surplus of the funds held in the Letter of Credit Collateral Account

and CarrAmerica LP hereunder and under any other Loan Document after the
Maturity Date shall be paid to the Borrowers or to whomsoever may be lawfully
entitled to receive such surplus.

Reference Bank in the relevant market for such Interest Period, or

                  (b) Banks having 50% or more of the aggregate amount of the
Commitments advise the Lead Agent that the Adjusted London Interbank Offered
Rate as determined by the Lead Agent will not adequately and fairly reflect the
cost to such Banks of funding their Euro-Dollar Loans for such Interest Period,
the Lead Agent shall forthwith give notice thereof to the Borrowers and the
Banks, whereupon until the Lead Agent notifies the Borrowers that the
circumstances giving rise to such suspension no longer exist, the obligations of
the Banks to make Euro-Dollar Loans shall be suspended. Unless the applicable
Borrower notifies the Lead Agent at least two Domestic Business Days before the
date of any Euro-Dollar Borrowing or Money Market LIBOR Borrowing for which a
Notice of Borrowing has previously been given that it elects not to borrow on
such date, (i) if such Borrowing is a Committed Borrowing, such Borrowing shall
instead be made as a Base Rate Borrowing and (ii) if such Borrowing is a Money
Market LIBOR Borrowing, the Money Market LIBOR Loans comprising such Borrowing
shall bear interest for each day from and including the first day to but
excluding the last day of the Interest Period applicable thereto at the Base
Rate for such day.

                  SECTION 8.2. Illegality. If, after the date of this Agreement,
the adoption of any applicable law, rule or regulation, or any change in any
existing applicable law, rule or regulation, or any change in the interpretation
or administration thereof by any governmental authority, central bank or
comparable agency charged with the interpretation or administration thereof, or
compliance by any Bank (or its Euro-Dollar Lending Office) with any request or
directive (whether or not having the force of law) of any such authority,
central bank or comparable agency shall make it unlawful or impossible for any
Bank (or its Euro-Dollar Lending Office) to make, maintain or fund its
Euro-Dollar Loans or Money Market LIBOR Loans or to participate in any Letter of
Credit issued by the Fronting Bank or, with respect to the Fronting Bank, to
issue any Letters of Credit, and such Bank shall so notify the Lead Agent, the
Lead Agent shall forthwith give notice thereof to the other Banks and the

                                       91
<PAGE>

Borrowers, whereupon until such Bank notifies the Borrowers and the Lead Agent
that the circumstances giving rise to such suspension no longer exist, the
obligation of such Bank to make Euro-Dollar Loans or Money Market LIBOR Loans or
to participate in any Letter of Credit issued by the Fronting Bank or, with
respect to the Fronting Bank, to issue any Letters of Credit, shall be
suspended. With respect to Euro-Dollar Loans or Money Market LIBOR Loans, before
giving any notice to the Lead Agent pursuant to this Section, such Bank shall
designate a different Euro-Dollar Lending Office if such designation will avoid
the need for giving such notice and will not, in the judgment of such Bank, be
otherwise disadvantageous to such Bank. If such Bank shall determine that it may
not lawfully continue to maintain and fund any of its outstanding Euro-Dollar
Loans or Money Market LIBOR Loans (as the case may be) to maturity and shall so
specify in such notice, the Borrowers and/or CarrAmerica LP shall immediately
prepay in full the then outstanding principal amount of each such Euro-Dollar
Loan or Money Market LIBOR Loan, together with accrued interest thereon.
Concurrently with prepaying each such Euro-Dollar Loan, the Borrowers shall
borrow a Base Rate Loan in an equal principal amount from such Bank (on which
interest and principal shall be payable contemporaneously with the related
Euro-Dollar Loans or Money Market LIBOR Loan of the other Banks), and such Bank
shall make such a Base Rate Loan.

                  SECTION 8.3. Increased Cost and Reduced Return.

                  (a) If on or after (x) the date hereof, in the case of any
Committed Loan or any obligation to make Committed Loans or (y) the date of the
applicable Money Market Quote, in the case of any Money Market Loan, the
adoption of any applicable law, rule or regulation, or any change in any
applicable law, rule or regulation, or any change in the interpretation or
administration thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof, or compliance
by any Bank (or its Applicable Lending Office) with any request or directive
(whether or not having the force of law) of any such authority, central bank or
comparable agency shall impose, modify or deem applicable any reserve
(including, without limitation, any such requirement imposed by the Board of
Governors of the Federal Reserve System (but excluding with respect to any
Euro-Dollar Loan any such requirement reflected in an applicable Euro-Dollar
Reserve Percentage)), special deposit, insurance assessment or similar
requirement against assets of, deposits with or for the account of, or credit
extended by, any Bank (or its Applicable Lending Office) or shall impose on any

                                       92
<PAGE>

Bank (or its Applicable Lending Office) or on the London interbank market any
other condition affecting its Euro-Dollar Loans or Money Market LIBOR Loans, its
Note, or its obligation to make Euro-Dollar Loans, and the result of any of the
foregoing is to increase the cost to such Bank (or its Applicable Lending
Office) of making or maintaining any such Loans, or to reduce the amount of any
sum received or receivable by such Bank (or its Applicable Lending Office) under
this Agreement or under its Note with respect thereto, by an amount deemed by
such Bank to be material, then, within 15 days after demand by such Bank (with a
copy to the Lead Agent), which demand shall be accompanied by a certificate
showing, in reasonable detail, the calculation of such amount or amounts, the
Borrowers and/or CarrAmerica LP shall pay to such Bank such additional amount or
amounts as will compensate such Bank for such increased cost or reduction.

                  (b) If any Bank shall have determined that, after the date
hereof, the adoption of any applicable law, rule or regulation regarding capital
adequacy, or any change in any such law, rule or regulation, or any change in
the interpretation or administration thereof by any governmental authority,
central bank or comparable agency charged with the interpretation or
administration thereof, or any request or directive regarding capital adequacy
(whether or not having the force of law) of any such authority, central bank or
comparable agency, has or would have the effect of reducing the rate of return
on capital of such Bank (or its Parent) as a consequence of such Bank's
obligations hereunder to a level below that which such Bank (or its Parent)
could have achieved but for such adoption, change, request or directive (taking
into consideration its policies with respect to capital adequacy) by an amount
deemed by such Bank to be material, then from time to time, within 15 days after
demand by such Bank (with a copy to the Lead Agent), which demand shall be
accompanied by a certificate showing, in reasonable detail, the calculation of
such amount or amounts, the Borrowers and/or CarrAmerica LP shall pay to such
Bank such additional amount or amounts as will compensate such Bank (or its
Parent) for such reduction.

                  (c) Each Bank will promptly notify the Borrowers and
CarrAmerica LP and the Lead Agent of any event of which it has knowledge,
occurring after the date hereof, which will entitle such Bank to compensation
pursuant to this Section and will designate a different Applicable Lending
Office if such designation will avoid the need for, or reduce the amount of,
such compensation and will not, in the judgment of such Bank, be otherwise
disadvantageous to such Bank. A certificate of any Bank claiming compensation
under this Section and setting forth the additional amount or amounts to be paid
to it hereunder shall be conclusive in the absence of manifest error. In
determining such amount, such Bank may use any reasonable averaging and
attribution methods.

                  SECTION 8.4. Taxes.

                  (a) Any and all payments by the Borrowers or CarrAmerica LP to
or for the account of any Bank or the Lead Agent hereunder or under any other
Loan Document shall be made free and clear of and without deduction for any and
all present or future taxes, duties, levies, imposts, deductions, charges or
withholdings, and all liabilities with respect thereto, excluding, in the case
of each Bank and the Lead Agent, taxes imposed on its income, and franchise
taxes imposed on it, by the jurisdiction under the laws of which such Bank or
the Lead Agent (as the case may be) is organized or any political subdivision
thereof and, in the case of each Bank, taxes imposed on its income, and
franchise or similar taxes imposed on it, by the jurisdiction of such Bank's
Applicable Lending Office or any political subdivision thereof (and, if
different from the jurisdiction of such Bank's Applicable Lending Office, the
jurisdiction of the domicile of its Loans either established by the Bank
pursuant to Section 9.12 or determined by the applicable taxing authorities)(all
such non-excluded taxes, duties, levies, imposts, deductions, charges,
withholdings and liabilities being hereinafter referred to as "Taxes"). If the
Borrowers and/or CarrAmerica LP shall be required by law to deduct any Taxes
from or in respect of any sum payable hereunder or under any Note or Letter of
Credit or participation therein to any Bank or the Lead Agent, (i) the sum
payable shall be increased as necessary so that after making all required
deductions (including deductions applicable to additional sums payable under
this Section 8.4) such Bank, the Fronting Bank or the Lead Agent (as the case
may be) receives an amount equal to the sum it would have received had no such
deductions been made, (ii) the Borrowers or CarrAmerica LP shall make such
deductions, (iii) the Borrowers or CarrAmerica LP shall pay the full amount
deducted to the relevant taxation authority or other authority in accordance
with applicable law and (iv) the Borrowers or CarrAmerica LP shall furnish to
the Lead Agent, at its address referred to in Section 9.1, the original or a
certified copy of a receipt evidencing payment thereof.

                  (b) In addition, the Borrowers and CarrAmerica LP agree to pay
any present or future stamp or documentary taxes and any other excise or
property taxes, or charges or similar levies which arise from any payment made
hereunder or under any Note or Letter of Credit or participation therein or from
the execution or delivery of, or otherwise with respect to, this Agreement or
any Note or Letter of Credit or participation therein (hereinafter referred to
as "Other Taxes").

                                       94
<PAGE>

                  (c) The Borrowers and CarrAmerica LP agree to indemnify each
Bank, the Fronting Bank and the Lead Agent for the full amount of Taxes or Other
Taxes (including, without limitation, any Taxes or Other Taxes imposed or
asserted by any jurisdiction on amounts payable under this Section 8.4) paid by
such Bank, the Fronting Bank or the Lead Agent (as the case may be) and any
liability (including penalties, interest and expenses) arising there from or
with respect thereto. This indemnification shall be made within 15 days from the
date such Bank, the Fronting Bank or the Lead Agent (as the case may be) makes
demand therefor.

                  (d) Each Bank organized under the laws of a jurisdiction
outside the United States, on or prior to the date of its execution and delivery
of this Agreement in the case of each Bank listed on the signature pages hereof
and on or prior to the date on which it becomes a Bank in the case of each other
Bank, and from time to time thereafter if requested in writing by the Borrowers
or CarrAmerica LP (but only so long as such Bank remains lawfully able to do
so), shall provide the Borrowers or CarrAmerica LP with Internal Revenue Service
form 1001 or 4224, as appropriate, or any successor form prescribed by the
Internal Revenue Service, certifying that such Bank is entitled to benefits
under an income tax treaty to which the United States is a party which reduces
the rate of withholding tax on payments of interest or certifying that the
income receivable pursuant to this Agreement is effectively connected with the
conduct of a trade or business in the United States. If the form provided by a
Bank at the time such Bank first became a party to this Agreement or at any time
thereafter (other than solely by reason of a change in United States law or a
change in the terms of any treaty to which the United States is a party after
the date hereof) indicates a United States interest withholding tax rate in
excess of zero (or would have indicated such a withholding tax rate if such form
had been submitted and completed accurately and completely and either was not
submitted or was not completed accurately and completely), or if a Bank
otherwise is subject to United States interest withholding tax at a rate in
excess of zero at any time for any reason (other than solely by reason of a
change in United States law or regulation or a change in any treaty to which the
United States is a party after the date hereof), withholding tax at such rate
shall be considered excluded from "Taxes" as defined in Section 8.4(a). In
addition, any amount that otherwise would be considered "Taxes" or "Other Taxes"
for purposes of this Section 8.4 shall be excluded therefrom if the Bank either
has transferred the domicile of its Loans pursuant to Section 9.12 or changed
the Applicable Lending Office with respect to such Loans and such amount would
not have been incurred had such transfer or change not been made.

                                       95
<PAGE>

                  (e) For any period with respect to which a Bank has failed to
provide the Borrowers or CarrAmerica LP with the appropriate form pursuant to
Section 8.4(d) (unless such failure is due to a change in treaty, law or
regulation occurring subsequent to the date on which a form originally was
required to be provided), such Bank shall not be entitled to indemnification
under Section 8.4(a) with respect to Taxes imposed by the United States;
provided, however, that should a Bank, which is otherwise exempt from or subject
to a reduced rate of withholding tax, become subject to Taxes because of its
failure to deliver a form required hereunder, the Borrowers and CarrAmerica LP
shall take such steps as such Bank shall reasonably request to assist such Bank
to recover such Taxes.

                  (f) If the Borrowers or CarrAmerica LP are required to pay
additional amounts to or for the account of any Bank pursuant to this Section
8.4, then such Bank will change the jurisdiction of its Applicable Lending
Office so as to eliminate or reduce any such additional payment which may
thereafter accrue if such change, in the judgment of such Bank, is not otherwise
disadvantageous to such Bank.

                  SECTION 8.5. Base Rate Loans Substituted for Affected
Euro-Dollar Loans. If (i) the obligation of any Bank to make Euro-Dollar Loans
has been suspended pursuant to Sections 8.1 or 8.2 or (ii) any Bank has demanded
compensation under Section 8.3 or 8.4 with respect to its Euro-Dollar Loans and
the Borrowers shall, by at least five Euro-Dollar Business Days' prior notice to
such Bank through the Lead Agent, have elected that the provisions of this
Section shall apply to such Bank, then, unless and until such Bank notifies the
Borrowers that the circumstances giving rise to such suspension or demand for
compensation no longer exist:

                  (a) all Loans which would otherwise be made by such Bank as
Euro-Dollar Loans shall be made instead as Base Rate Loans (on which interest
and principal shall be payable contemporaneously with the related Euro-Dollar
Loans of the other Banks), and

                                       96
<PAGE>

                  (b) after each of its Euro-Dollar Loans has been repaid, all
payments of principal which would otherwise be applied to repay such Euro-Dollar
Loans shall be applied to repay its Base Rate Loans instead.

                                  MISCELLANEOUS

other address or telecopy number as such party may hereafter specify for the
purpose by notice to the Lead Agent, the Banks, the Borrowers and CarrAmerica
LP. Each such notice, request or other communication shall be effective (i) if

specified in this Section, (ii) if given by mail, 72 hours after such
communication is deposited in the mails with first class postage prepaid,

the address specified in this Section; provided that notices to the Lead Agent
under Article II or Article VIII shall not be effective until received.

                  SECTION 9.2. No Waivers. No failure or delay by the Lead
Agent or any Bank in exercising any right, power or privilege hereunder or under
any Note shall operate as a waiver thereof nor shall any single or partial
exercise thereof preclude any other or further exercise thereof or the exercise
of any other right, power or privilege. The rights and remedies herein provided
shall be cumulative and not exclusive of any rights or remedies provided by law.

                  SECTION 9.3. Expenses; Indemnification.

                  (a) The Borrowers and CarrAmerica LP shall pay (i) all
reasonable out-of-pocket expenses of the Lead Agent (including, without
limitation, reasonable fees and disbursements of special counsel Skadden, Arps,
Slate, Meagher & Flom, local counsel for the Lead Agent, and travel,
environmental and engineering expenses), in connection with the preparation and
administration of this Agreement, the Loan Documents and the documents and
instruments referred to therein, the syndication of the Loans, any waiver or
consent hereunder or any amendment or modification hereof or any Default or
alleged Default hereunder and (ii) if an Event of Default occurs, all
out-of-pocket expenses incurred by the Lead Agent and each Bank, including,
without limitation, reasonable fees and disbursements of counsel for the Lead
Agent, in connection with the enforcement of the Loan Documents and the
instruments referred to therein and such Event of Default and collection,
bankruptcy, insolvency and other enforcement proceedings resulting therefrom.

                  (b) The Borrowers and CarrAmerica LP agree to indemnify the
Lead Agent and each Bank, their respective affiliates and the respective
directors, officers, agents and employees of the foregoing (each an
"Indemnitee") and hold each Indemnitee harmless from and against any and all
liabilities, losses, damages, costs and expenses of any kind, including, without
limitation, the reasonable fees and disbursements of counsel, which may be
incurred by such Indemnitee in connection with any investigative, administrative
or judicial proceeding (whether or not such Indemnitee shall be designated a
party thereto) that may at any time (including, without limitation, at any time
following the payment of the Obligations) be imposed on, asserted against or
incurred by any Indemnitee as a result of, or arising out of, or in any way
related to or by reason of, (i) any of the transactions contemplated by the Loan
Documents or the execution, delivery or performance of any Loan Document, (ii)
any violation by the Borrowers, CarrAmerica LP or the Environmental Affiliates
of any applicable Environmental Law, (iii) any Environmental Claim arising out
of the management, use, control, ownership or operation of property or assets
by the Borrowers, CarrAmerica LP or any of the Environmental Affiliates,

                                       98
<PAGE>

including, without limitation, all on-site and off-site activities involving
Materials of Environmental Concern, (iv) the breach of any environmental
representation or warranty set forth herein, (v) the grant to the Lead Agent and
the Banks of any Lien in any property or assets of the Borrowers or CarrAmerica
LP or any stock or other equity interest in the Borrowers or CarrAmerica LP, and
(vi) the exercise by the Lead Agent and the Banks of their rights and remedies
(including, without limitation, foreclosure) under any agreements creating any
such Lien (but excluding, as to any Indemnitee, any such losses, liabilities,
claims, damages, expenses, obligations, penalties, actions, judgments, suits,
costs or disbursements incurred solely by reason of (i) the gross negligence or
willful misconduct of such Indemnitee as finally determined by a court of
competent jurisdiction and (ii) any investigative, administrative or judicial
proceeding imposed or asserted against any Indemnitee by any bank regulatory
agency or by any equity holder of such Indemnitee). Carr and CarrAmerica LP
shall be jointly and severally liable for all Obligations arising hereunder in
connection with the Tranche A Loans and Carr and Carr LP shall be jointly and
severally liable for all Obligations arising hereunder in connection with the
Tranche B Loans. Notwithstanding the foregoing, Carr LP shall not be liable for
any Borrowings made by Carr pursuant to the terms hereof. The Borrowers' and
CarrAmerica LP's obligations under this Section shall survive the termination of
this Agreement and the payment of the Obligations.

                  (c) The Borrowers and CarrAmerica LP shall pay, and hold the
Lead Agent and each of the Banks harmless from and against, any and all present
and future U.S. stamp, recording, transfer and other similar foreclosure related
taxes with respect to the fore going matters and hold the Lead Agent and each
Bank harmless from and against any and all liabilities with respect to or
resulting from any delay or omission (other than to the extent attributable to
such Bank) to pay such taxes.

                  SECTION 9.4. Sharing of Set-Offs. In addition to any rights
now or hereafter granted under applicable law or otherwise, and not by way of
limitation of any such rights, upon the occurrence and during the continuance of
any Event of Default, each Bank is hereby authorized at any time or from time to
time, without presentment, demand, protest or other notice of any kind to the
Borrowers, CarrAmerica LP or to any other Person, any such notice being hereby
expressly waived, to set off and to appropriate and apply any and all deposits

                                       99
<PAGE>

(general or special, time or demand, provisional or final), other than deposits
held for the benefit of third parties, and any other indebtedness at any time
held or owing by such Bank (including, without limitation, by branches and
agencies of such Bank wherever located) to or for the credit or the account of
the Borrowers or CarrAmerica LP against and on account of the Obligations of the
Borrowers or CarrAmerica LP then due and payable to such Bank under this
Agreement or under any of the other Loan Documents, including, without
limitation, all interests in Obligations purchased by such Bank. Each Bank
agrees that if it shall, by exercising any right of set-off or counterclaim or
otherwise, receive payment of a proportion of the aggregate amount of principal
and interest due with respect to any Note held by it or Letter of Credit
participated in by it, or, in the case of the Fronting Bank, Letter of Credit
issued by it, which is greater than the proportion received by any other Bank or
Letter of Credit issued or participated in by such other Bank, in respect of the
aggregate amount of principal and interest due with respect to any Note held by
such other Bank, the Bank receiving such proportionately greater payment shall
purchase such participations in the Notes held by the other Banks or Letter of
Credit issued or participated in by such other Bank, and such other adjustments
shall be made, as may be required so that all such payments of principal and
interest with respect to the Notes held by the Banks or Letter of Credit issued
or participated in by such other Banks shall be shared by the Banks pro rata;
provided that nothing in this Section shall impair the right of any Bank to
exercise any right of set-off or counterclaim it may have and to apply the
amount subject to such exercise to the payment of indebtedness of the Borrowers
or CarrAmerica LP other than their indebtedness under the Notes or the Letters
of Credit. The Borrowers and CarrAmerica LP agree, to the fullest extent they
may effectively do so under applicable law, that any holder of a participation
in a Note or Letter of Credit, whether or not acquired pursuant to the foregoing
arrangements, may exercise rights of set-off or counterclaim and other rights
with respect to such participation as fully as if such holder of a participation
were a direct creditor of the Borrowers or CarrAmerica LP in the amount of such
participation. Notwithstanding the foregoing, any Bank shall not exercise any
right of set-off or counterclaim or any similar right it may have against any
other indebtedness at any time held or owing by such Bank (including, without
limitation, by branches and agencies of such Bank wherever located) to or for
the credit or the account of Carr LP against and on account of any Obligations
of Carr (whether or not then due and payable) or to apply the amount subject to
such exercise to the payment of indebtedness or other Obligations of Carr.

                  SECTION 9.5. Amendments and Waivers. Any provision of this
Agreement, the Notes, the Letters of Credit or other Loan Documents may be
amended or waived if, but only if, such amendment or waiver is in writing and is
signed by the Borrowers and the Required Banks (and, if the rights or duties of
the Lead Agent are affected thereby, by the Lead Agent); provided that no such
amendment or waiver shall, unless signed by all the Banks, (i) in crease or
decrease the Commitment of any Bank (except for a ratable decrease in the
Commitments of all Banks) or subject any Bank to any additional obligation, (ii)

                                      100
<PAGE>

reduce the principal of or rate of interest on any Loan or any fees specified
herein, including, without limitation, the waiver of any Default or Event of
Default in the payment of interest, principal or fees hereunder if such waiver
would result in a permanent reduction in the amount or change in the timing of
the payment of interest, principal or fees payable hereunder by Borrowers or
CarrAmerica LP, unless the Borrowers or CarrAmerica LP have cured such Default
or Event of Default and paid all amounts, including any default interest, due
hereunder at the time a request for consent is made by Lead Agent to the Banks
to the waiver of any Default or Event of Default in the payment of interest,
principal or fees hereunder, in which event only the consent of the Required
Banks to the waiver of such Default or Event of Default shall be required, (iii)
postpone the date fixed for any payment of principal of or interest on any Loan
or any fees hereunder or for any reduction or termination of any Commitment,
(iv) change the percentage of the Commitments or of the aggregate unpaid
principal amount of the Notes, or the number of Banks, which shall be required
for the Banks or any of them to take any action under this Section or any other
provision of this Agreement, or (v) amend the provisions of this Section 9.5.
Notwithstanding the foregoing, no amendment, waiver or consent shall, unless in
writing and signed by the Designating Lender on behalf of its Designated Lender
affected thereby, (a) subject such Designated Lender to any additional
obligations, (b) reduce the principal of, interest on, or other amounts due with
respect to, the Designated Lender Note made payable to such Designated Lender,
or (c) postpone any date fixed for any payment of principal of, or interest on,
or other amounts due with respect to the Designated Lender Note made payable to
the Designated Lender.

                  SECTION 9.6. Successors and Assigns.

                  (a) The provisions of this Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective successors and
assigns, except that the Borrowers may not assign or otherwise transfer any of
their rights under this Agreement or the other Loan Documents without the prior
written consent of all Banks.

                  (b) Any Bank may at any time grant to one or more banks or
other institutions (each a "Participant") participating interests in its
Commitment or any or all of its Loans. In the event of any such grant by a Bank
of a participating interest to a Participant, whether or not upon notice to the
Borrowers, CarrAmerica LP and the Lead Agent, such Bank shall remain responsible
for the performance of its obligations hereunder, and the Borrowers, CarrAmerica
LP and the Lead Agent shall continue to deal solely and directly with such Bank

                                      101
<PAGE>

in connection with such Bank's rights and obligations under this Agreement. Any
agreement pursuant to which any Bank may grant such a participating interest
shall provide that such Bank shall retain the sole right and responsibility to
enforce the obligations of the Borrowers and CarrAmerica LP hereunder including,
without limitation, the right to approve any amendment, modification or waiver
of any provision of this Agreement; provided that such participation agreement
may provide that such Bank will not agree to any modification, amendment or
waiver of this Agreement described in clause (i), (ii), (iii) or (iv) of Section
9.5 without the consent of the Participant. The Borrowers and CarrAmerica LP
agree that each Participant shall, to the extent provided in its participation
agreement, be entitled to the benefits of Article VIII with respect to its
participating interest. An assignment or other transfer which is not permitted
by subsection (c) or (d) below shall be given effect for purposes of this
Agreement only to the extent of a participating interest granted in accordance
with this subsection (b).

                  (c) Any Bank may at any time assign to one or more banks or
other institutions (each an "Assignee") all, or a proportionate part of all, of
its rights and obligations under this Agreement, the Notes and the other Loan
Documents, and such Assignee shall assume such rights and obligations, pursuant
to an Assignment and Assumption Agreement in substantially the form of Exhibit C
attached hereto executed by such Assignee and such transferor Bank, with (and
subject to) the consent of the Lead Agent and, provided no Event of Default
shall have occurred and be continuing, the Borrowers, which consent shall not
be unreasonably withheld or delayed. Notwithstanding the foregoing, however, if
at any time any Bank shall hold Commitments hereunder that, together with
commitments (the "Omni Commitments") it holds pursuant to the provisions of the
Amended and Restated Revolving Credit Agreement, dated as of even date herewith,
among OmniOffices, Inc., the Lead Agent and the Banks, exceeds $75,000,000 in
the aggregate, then, provided that the amount such Bank shall desire to assign
pursuant to the provisions of this Section shall be not less than $10,000,000,
then no consent of either the Lead Agent or the Borrowers shall be required
until such time as such Bank's aggregate Commitments and Omni Commitments shall
equal or be less than $75,000,000. Upon execution and delivery of such
instrument and payment by such Assignee to such transferor Bank of an amount
equal to the purchase price agreed between such transferor Bank and such
Assignee, such Assignee shall be a Bank party to this Agreement and shall have
all the rights and obligations of a Bank with a Commitment as set forth in such
instrument of assumption, and the transferor Bank shall be released from its

                                      102
<PAGE>

obligations hereunder to a corresponding extent, and no further consent or
action by any party shall be required. Upon the consummation of any assignment
pursuant to this subsection (c), the transferor Bank, the Lead Agent, the
Borrowers and CarrAmerica LP, if applicable, shall make appropriate
arrangements so that, if required, a new Note or Notes are issued to the
Assignee. In connection with any such assignment, the transferor Bank shall pay
to the Lead Agent an administrative fee for processing such assignment in the
amount of $2,500. If the Assignee is not incorporated under the laws of the
United States of America or a state thereof, it shall deliver to the Borrowers
and the Lead Agent certification as to exemption from deduction or withholding
of any United States federal income taxes in accordance with Section 8.4.

                  (d) Any Bank (each, a "Designating Lender") may at any time
designate one Designated Lender to fund Money Market Loans on behalf of such
Designating Lender subject to the terms of this Section 9.6(d) and the
provisions in Section 9.6(b) and (c) shall not apply to such designation. No
Bank may designate more than one (1) Designated Lender at a time. The parties to
each such designation shall execute and deliver to the Lead Agent for its
acceptance a Designation Agreement in the form of Exhibit G hereto. Upon such
receipt of an appropriately completed Designation Agreement executed by a
Designating Lender and a designee representing that it is a Designated Lender,

                                      103
<PAGE>

the Lead Agent will accept such Designation Agreement and will give prompt
notice thereof to the Borrowers and CarrAmerica LP, whereupon, (i) the Borrower
shall execute and deliver to the Designating Bank a Designated Lender Note
payable to the order of the Designated Lender, (ii) from and after the effective
date specified in the Designation Agreement, the Designated Lender shall become
a party to this Agreement with a right (subject to the provisions of Section
2.3(d)) to make Money Market Loans on behalf of its Designating Lender pursuant
to Section 2.3 after the Borrower has accepted a Money Market Loan (or portion
thereof) of the Designating Lender, and (iii) the Designated Lender shall not be
required to make payments with respect to any obligations in this Agreement
except to the extent of excess cash flow of such Designated Lender which is not
otherwise required to repay obligations of such Designated Lender which are then
due and payable; provided, however, that regardless of such designation and
assumption by the Designated Lender, the Designating Lender shall be and remain
obligated to the Borrower, the Agents and the Banks for each and every of the
obligations of the Designating Lender and its related Designated Lender with
respect to this Agreement, including, without limitation, any indemnification
obligations under Section 7.6 hereof and any sums otherwise payable to the
Borrower by the Designated Lender. Each Designating Lender shall serve as the
administrative agent of the Designated Lender and shall on behalf of, and to the
exclusion of, the Designated Lender: (i) receive any and all payments made for
the benefit of the Designated Lender and (ii) give and receive all
communications and notices and take all actions hereunder, including, without
limitation, votes, approvals, waivers, consents and amendments under or relating
to this Agreement and the other Loan Documents. Any such notice, communication,
vote, approval, waiver, consent or amendment shall be signed by the Designating
Lender as administrative agent for the Designated Lender and shall not be signed
by the Designated Lender on its own behalf and shall be binding upon the
Designated Lender to the same extent as if signed by the Designated Lender on
its own behalf. The Borrower, the Lead Agent, the Agents and the Banks may rely
thereon without any requirement that the Designated Lender sign or acknowledge
the same. No Designated Lender may assign or transfer all or any portion of its
interest hereunder or under any other Loan Document, other than assignments to
the Designating Lender which originally designated such Designated Lender or
otherwise in accordance with the provisions of Section 9.6 (b) and (c).

                  (e) Any Bank may at any time assign all or any portion of its
rights under this Agreement and its Note and the Letters of Credit participated
in by such Bank (as a Fronting Bank) or, in the case of the Fronting Bank,
issued by it, to a Federal Reserve Bank. No such assignment shall release the
transferor Bank from its obligations hereunder.

                  (f) No Assignee, Participant or other transferee of any Bank's
rights shall be entitled to receive any greater payment under Section 8.3 or 8.4
than such Bank would have been entitled to receive with respect to the rights
transferred, unless such transfer is made with the Borrowers' prior written
consent or by reason of the provisions of Section 8.2, 8.3 or 8.4 requiring such
Bank to designate a different Applicable Lending Office under certain
circumstances or at a time when the circumstances giving rise to such greater
payment did not exist.

                  SECTION 9.7. Governing Law; Submission to Jurisdiction.

                  (a) THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS AND THE RIGHTS
AND OBLIGATIONS OF THE PARTIES HEREUNDER AND THEREUNDER SHALL BE CONSTRUED IN
ACCORDANCE WITH AND BE GOVERNED BY THE LAWS OF THE STATE OF NEW YORK (WITHOUT
GIVING EFFECT TO THE PRINCIPLES THEREOF RELATING TO CONFLICTS OF LAW).

                  (b) Any legal action or proceeding with respect to this
Agreement or any other Loan Document and any action for enforcement of any
judgment in respect thereof may be brought in the courts of the State of New
York or of the United States of America for the Southern District of New York,
and, by execution and delivery of this Agreement, each Borrower and CarrAmerica
LP hereby accepts for itself and in respect of its property, generally and
unconditionally, the non-exclusive jurisdiction of the aforesaid courts and
appellate courts from any thereof. Each Borrower and CarrAmerica LP irrevocably
consents to the service of process out of any of the aforementioned courts in
any such action or proceeding by the hand delivery, or mailing of copies thereof
by registered or certified mail, postage prepaid, to the applicable Borrower or
CarrAmerica LP at its address set forth below. Each Borrower and CarrAmerica LP
hereby irrevocably waives any objection which it may now or hereafter have to
the laying of venue of any of the aforesaid actions or proceedings arising out
of or in connection with this Agreement or any other Loan Document brought in
the courts referred to above and hereby further irrevocably waives and agrees
not to plead or claim in any such court that any such action or proceeding
brought in any such court has been brought in an inconvenient forum. Nothing
herein shall affect the right of the Lead Agent, any Bank or any holder of a
Note to serve process in any other manner permitted by law or to commence legal
proceedings or otherwise proceed against the Borrowers or CarrAmerica LP in any
other jurisdiction.

                  Section 9.8. Marshalling; Recapture. Neither the Lead Agent
nor any Bank shall be under any obligation to marshall any assets in favor of
the Borrowers, CarrAmerica LP or any other party or against or in payment of any
or all of the Obligations. To the extent any Bank receives any payment by or on
behalf of the Borrowers or CarrAmerica LP, which payment or any part thereof is
subsequently invalidated, declared to be fraudulent or preferential, set aside
or required to be repaid to either Borrower or CarrAmerica LP or its estate,
trustee, receiver, custodian or any other party under any bankruptcy law, state
or federal law, common law or equitable cause, then to the extent of such
payment or repayment, the Obligation or part thereof which has been paid,
reduced or satisfied by the amount so repaid shall be reinstated by the amount
so repaid and shall be included within the liabilities of the Borrowers and
CarrAmerica LP to such Bank as of the date such initial payment, reduction or
satisfaction occurred.

                  SECTION 9.9. Counterparts; Integration; Effectiveness. This
Agreement may be signed in any number of counterparts, each of which shall be an
original, with the same effect as if the signatures thereto and hereto were upon
the same instrument. This Agreement constitutes the entire agreement and
understanding among the parties hereto and supersedes any and all prior
agreements and understandings, oral or written, relating to the subject matter
hereof. This Agreement shall become effective upon receipt by the Lead Agent of
counterparts hereof signed by each of the parties hereto (or, in the case of any
party as to which an executed counterpart shall not have been received, receipt
by the Lead Agent in form satisfactory to it of telegraphic, telex or other
written confirmation from such party of execution of a counterpart hereof by
such party).

                  SECTION 9.10. WAIVER OF JURY TRIAL. EACH OF THE BORROWERS,
CARRAMERICA LP, THE LEAD AGENT AND THE BANKS HEREBY IRREVOCABLY WAIVE ANY AND
ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO
THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

                  SECTION 9.11. Survival. All indemnities set forth herein

Documents and the making and repayment of the Loans hereunder.

                  SECTION 9.12. Domicile of Loans. Subject to the provisions of
Article VIII, each Bank may transfer and carry its Loans at, to or for the
account of any domestic or foreign branch office, subsidiary or affiliate of
such Bank.

                  SECTION 9.13. Limitation of Liability. (a) No claim may be
made by the Borrowers, CarrAmerica LP or any other Person against the Lead Agent
or any Bank or the affiliates, directors, officers, employees, attorneys or
agents of any of them for any consequential or punitive damages in respect of
any claim for breach of contract or any other theory of liability arising out of
or related to the transactions contemplated by this Agreement or by the other
Loan Documents, or any act, omission or event occur ring in connection
therewith; and each Borrower and CarrAmerica LP hereby waives, releases and
agrees not to sue upon any claim for any such damages, whether or not accrued
and whether or not known or suspected to exist in its favor.

                  (b) The Lead Agent or any Bank may look to all the assets of
the Borrowers and CarrAmerica LP in seeking to enforce the Borrowers' and
CarrAmerica LP's liability and obligations hereunder, and the lien of any

                                      106
<PAGE>

judgment against the Borrowers and CarrAmerica LP and any proceeding instituted
on, under or in connection with any Note or any of the other Loan Documents
shall extend to all property now or hereafter owned by the Borrowers and
CarrAmerica LP, except as set forth in Sections 6.2 and 9.3.

with its customary policies for maintaining information as confidential, not to
disclose without the prior consent of the Borrowers (other than to its
subsidiaries, directors, agents, employees, auditors, counsel or other
professional consultants, provided that each such recipient shall either agree
to be bound by the terms of this Section 9.14 or is otherwise bound to keep such

nationally recognized rating agency or similar organization, (c) as may be
required or appropriate in response to any summons or subpoena or in connection
with any litigation, or (d) in order to comply with any applicable law, order,
regulation or ruling; provided, further that in the case of the foregoing
clauses (b), (c) and (d), such Bank shall use reasonable efforts to give Carr
prior notice of any such disclosure.

                  WHEREAS, as provided under the Credit Agreement, the Assignor
has a Commitment to make Loans to the Borrowers in an aggregate principal amount
at any time outstanding not to exceed $_____________;

                  WHEREAS, Loans made to the Borrowers by the Assignor under the
Credit Agreement in the aggregate principal amount of $____________ are
outstanding at the date hereof; and

                  WHEREAS, the Assignor proposes to assign to the Assignee all
of the rights of the Assignor under the Credit Agreement in respect of a portion
of its Commitment thereunder in an amount equal to $__________ (the "Assigned
Amount"), together with a corresponding portion of its outstanding Loans, and
the Assignee proposes to accept assignment of such rights and assume the
corresponding obligations from the Assignor on such terms;

                  NOW, THEREFORE, in consideration of the foregoing and the
mutual agreements contained herein, the parties hereto agree as follows:

                  SECTION 1.  Definitions.  All capitalized terms not
otherwise defined herein shall have the respective meanings set forth
in the Credit Agreement.


                                        1

<PAGE>



                  SECTION 2. Assignment. The Assignor hereby assigns and sells
to the Assignee all of the rights of the Assignor under the Credit Agreement to
the extent of the Assigned Amount, and the Assignee hereby accepts such
assignment from the Assignor and assumes all of the obligations of the Assignor
under the Credit Agreement to the extent of the Assigned Amount, including the
purchase from the Assignor of the corresponding portion of the principal amount
of the Loans made by the Assignor outstanding at the date hereof. Upon the
execution and delivery hereof by the Assignor, the Assignee, the Borrowers and
the Agent and the payment of the amounts specified in Section 3 required to be
paid on the date hereof (i) the Assignee shall, as of the date hereof, succeed
to the rights and be obligated to perform the obligations of a Bank under the
Credit Agreement with a Commitment in an amount equal to the Assigned Amount and
(ii) the Commitment of the Assignor shall, as of the date hereof, be reduced by
a like amount and the Assignor released from its obligations under the Credit
Agreement to the extent such obligations have been assumed by the Assignee. The
assignment provided for herein shall be without recourse to the Assignor.

                  SECTION 3. Payments. As consideration for the assignment and
sale contemplated in Section 2 hereof, the Assignee shall pay to the Assignor on
the date hereof in Federal funds the amount heretofore agreed between them
(1) It is understood that Commitment Fees accrued to the date hereof are for the
account of the Assignor and such fees accruing from and including the date
hereof are for the account of the Assignee. Each of the Assignor and the
Assignee hereby agrees that if it receives any amount under the Credit Agreement
which is for the account of the other party hereto, it shall receive the same
for the account of such other party to the extent of such other party's interest
therein and shall promptly pay the same to such other party.

                  SECTION 4. Consent of the Borrowers and the Agent. This
Agreement is conditioned upon the consent of the Borrowers and the Agent
pursuant to Section 9.6(c) of the Credit Agreement. The execution of this
Agreement by the Borrowers and the Agent is evidence of this consent. Pursuant
to Section 9.6(c) of the Credit Agreement, Carr agrees to execute and deliver a
Tranche A Note payable to the order of Assignee and Carr LP agrees to execute
and deliver a Tranche B Note payable to the order of the Assignee to evidence
the assignment and assumption provided for herein.

- --------
(1)  Amount should combine principal together with accrued interest and
     breakage compensation, if any, to be paid by the Assignee, net of any
     portion of any upfront fee to be paid by the Assignor to the As signee. It
     may be preferable in an appropriate case to specify these amounts
     generically or by formula rather than as a fixed sum.

Borrowers, or the validity and enforceability of the obligations of the
Borrowers in respect of the Credit Agreement or any Note. The Assignee
acknowledges that it has, independently and without reliance on the Assignor,
and based on such documents and information as it has deemed appropriate, made
its own credit analysis and decision to enter into this Agreement and will
continue to be responsible for making its own independent appraisal of the
business, affairs and financial condition of the Borrowers.

and construed in accordance with the laws of the State of New York

the Designee hereunder or thereunder, provided that the Designor shall not be

payable. Notwithstanding the foregoing, the Designor, as administrative agent
for the Designee, shall be and remain obligated to the Borrower, the Agents and

                                       17
<PAGE>

aggregate principal amount of at least $1,000,000, or an integral multiple of

Subject to the limitations set forth herein, any amounts repaid may be

                  SECTION 2.2. Notice of Borrowing. (a) The Borrower shall give

(y) the third Euro-Dollar Business Day before each Euro-Dollar Borrowing,
specifying:

                           (i)   the date of such Borrowing, which shall be a
Domestic Business Day in the case of a Domestic Borrowing or a Euro-Dollar
Business Day in the case of a Euro-Dollar Borrowing,

                           (ii)  the aggregate amount of such Borrowing,

                           (iii) whether the Loans comprising such Borrowing are
to be Base Rate Loans or Euro-Dollar Loans, and

                           (iv)  in the case of a Euro-Dollar Borrowing, the
duration of the Interest Period applicable thereto, subject to the provisions of
the definition of Interest Period.

                  (b) The Borrower shall give the Lead Agent, and the designated
Fronting Bank, written notice in the event that it desires to have Letters of
Credit (each, a "Letter of Credit") issued hereunder no later than 10:00 a.m.,
New York City time, at least four (4) Domestic Business Days prior to the date
of such issuance. Each such notice shall specify (i) the designated Fronting
Bank, (ii) the aggregate amount of the requested Letters of Credit, (iii) the
individual amount of each requested Letter of Credit and the number of Letters
of Credit to be issued, (iv) the date of such issuance (which shall be a
Domestic Business Day), (v) the name and address of the beneficiary, (vi) the
expiration date of the Letter of Credit (which in no event shall be later than
twelve (12) months after the issuance of such Letter of Credit or the Maturity


                                       18
<PAGE>

Date, whichever is earlier), (vii) the purpose and circumstances for which such
Letter of Credit is being issued and (viii) the terms upon which each such
Letter of Credit may be drawn down (which terms shall not leave any discretion
to Fronting Bank). Each such notice may be revoked telephonically by the
Borrower to the applicable Fronting Bank and the Lead Agent any time prior to
the date of issuance of the Letter of Credit by the applicable Fronting Bank,
provided such revocation is confirmed in writing by the Borrower to the Fronting
Bank and the Lead Agent within one (1) Domestic Business Day by facsimile. No
later than 10:00 a.m., New York City time, on the date that is four (4) Domestic
Business Days prior to the date of issuance, the Borrower shall specify a
precise description of the documents and the verbatim text of any certificate to
be presented by the beneficiary of such Letter of Credit, which if presented by
such beneficiary prior to the expiration date of the Letter of Credit would
require the Fronting Bank to make a payment under the Letter of Credit; provided
that Fronting Bank may, in its reasonable judgment, require changes in any such
documents and certificates only in conformity with changes in customary and
commercially reasonable practice or law and provided further, that no Letter of
Credit shall require payment against a conforming draft to be made thereunder on
the following Domestic Business Day that such draft is presented if such
presentation is made later than 10:00 A.M. New York City time (except that if
the beneficiary of any Letter of Credit requests at the time of the issuance of
its Letter of Credit that payment be made on the same Domestic Business Day
against a conforming draft, such beneficiary shall be entitled to such a same
day draw, provided such draft is presented to the applicable Fronting Bank no
later than 10:00 A.M. New York City time and provided further that, prior to the
issuance of such Letter of Credit, the Borrower shall have requested to Fronting
Bank and the Lead Agent that such beneficiary shall be entitled to a same day
draw). In determining whether to pay on such Letter of Credit, the Fronting Bank
shall be responsible only to determine that the documents and certificates
required to be delivered under the Letter of Credit have been delivered and that
they comply on their face with the requirements of that Letter of Credit.

                  SECTION 2.3. Intentionally Omitted.

                  SECTION 2.4. Notice to Banks; Funding of Loans.

                  (a) Upon receipt of a Notice of Borrowing, the Lead Agent
shall notify each Bank on the same day as it receives such Notice of Borrowing
of the contents thereof and of such Bank's share of such Borrowing and such
Notice of Borrowing shall not thereafter be revocable by the Borrower.

                                       19
<PAGE>

                  (b) Not later than 2:00 P.M. (New York City time) on the date
of each Borrowing as indicated in the Notice of Borrowing, each Bank shall
(except as provided in subsection (c) of this Section) make available its share
of such Borrowing, in Federal or other funds immediately available in New York
City, to the Lead Agent at its address referred to in Section 9.1. The Lead
Agent will make the funds so received from the Banks available to the Borrower
at the Lead Agent's aforesaid address. If the Borrower has requested the
issuance of a Letter of Credit, no later than 12:00 Noon (New York City time) on
the date of such issuance as indicated in the Notice of Borrowing, the Fronting
Bank shall issue such Letter of Credit in the amount so requested and deliver
the same to the Borrower with a copy thereof to the Lead Agent. Immediately upon
the issuance of each Letter of Credit by the Fronting Bank, such Fronting Bank
shall be deemed to have sold and transferred to each other Bank, and each such
other Bank shall be deemed to, and hereby agrees to, have irrevocably and
unconditionally purchased and received from Fronting Bank, without recourse or
warranty, an undivided interest and a participation in such Letter of Credit,
any drawing thereunder, and the obligations of the Borrower hereunder with
respect thereto, and any security therefor or guaranty pertaining thereto, in an
amount equal to such Bank's ratable share thereof (based upon the ratio its
Commitment bears to the aggregate of all Commitments). Upon any change in any of
the Commitments in accordance herewith, there shall be an automatic adjustment
to such participations to reflect such changed shares. The Fronting Bank shall
have the primary obligation to fund any and all draws made with respect to such
Letter of Credit notwithstanding any failure of a participating Bank to fund its
ratable share of any such draw. The Lead Agent will instruct the Fronting Bank
to make such Letter of Credit available to the Borrower and the Fronting Bank
shall make such Letter of Credit available to the Borrower at the Borrower's
aforesaid address on the date of the Borrowing.

                  (c) Unless the Lead Agent shall have received notice from a
Bank prior to the date of any Borrowing that such Bank will not make available
to the Lead Agent such Bank's share of such Borrowing, the Lead Agent may assume
that such Bank has made such share available to the Lead Agent on the date of
such Borrowing in accordance with subsection (b) of this Section 2.4 and the
Lead Agent may, in reliance upon such assumption, make available to the Borrower


                                       20
<PAGE>

on such date a corresponding amount. If and to the extent that such Bank shall
not have so made such share available to the Lead Agent, such Bank and the
Borrower agree to repay to the Lead Agent forthwith on demand such corresponding
amount together with interest thereon, for each day from the date such amount is
made available to the Borrower until the date such amount is repaid to the Lead
Agent, at (i) in the case of Borrower, a rate per annum equal to the higher of
the Federal Funds Rate and the interest rate applicable thereto pursuant to
Section 2.7 and (ii) in the case of such Bank, the Federal Funds Rate. If such
Bank shall repay to the Lead Agent such corresponding amount, such amount so
repaid shall constitute such Bank's Loan included in such Borrowing for purposes
of this Agreement.

                  SECTION 2.5. Notes.

                  (a) The Loans shall be evidenced by the Notes, each of which
shall be payable to the order of each Bank for the account of its Applicable
Lending Office in an amount equal to each such Bank's Commitment.

                  (b) Each Bank may, by notice to the Borrower and the Lead
Agent, request that its Loans of a particular type be evidenced by a separate
Note in an amount equal to the aggregate unpaid principal amount of such Loans.
Each such Note shall be in substantially the form of Exhibit A hereto. Each
reference in this Agreement to the "Note" of such Bank shall be deemed to refer
to and include any or all of such Notes, as the context may require.

                  (c) Upon receipt of each Bank's Note pursuant to Section
3.1(a) or (b) hereof, the Lead Agent shall forward such Note to such Bank. Each
Bank shall record the date, amount, type and maturity of each Loan made by it
and the date and amount of each payment of principal made by Borrower with
respect thereto, and may, if such Bank so elects in connection with any transfer
or enforcement of its Note, endorse on the schedule forming a part thereof
appropriate notations to evidence the foregoing information with respect to each
such Loan then outstanding; provided that the failure of any Bank to make any
such recordation or endorsement shall not affect the obligations of the Borrower
hereunder or under the Notes. Each Bank is hereby irrevocably authorized by the
Borrower so to endorse its Note and to attach to and make a part of its Note a
continuation of any such schedule as and when required.

                                       21

principal amount thereof, for each day from the date such Loan is made until it
becomes due, at a rate per annum equal to the sum of the Applicable Margin for
Base Rate Loans for such day plus the Base Rate for such day. Such interest
shall be payable for each Interest Period on the last day thereof.

                  (b) Each Euro-Dollar Loan shall bear interest on the
outstanding principal amount thereof, for each day during the Interest Period
applicable thereto, at a rate per annum equal to the sum of the Applicable
Margin for Euro-Dollar Loans for such day plus the Adjusted London Interbank
Offered Rate applicable to such Interest Period. Such interest shall be payable
for each Interest Period on the last day thereof and, if such Interest Period is
longer than three months, at intervals of three months after the first day
thereof.

                  "Adjusted London Interbank Offered Rate" applicable to any
Interest Period means a rate per annum equal to the quotient obtained (rounded
upward, if necessary, to the next higher 1/100 of 1%) by dividing (i) the
applicable London Interbank Offered Rate by (ii) 1.00 minus the Euro-Dollar
Reserve Percentage.

                  "Euro-Dollar Reserve Percentage" means for any day that
percentage (expressed as a decimal) which is in effect on such day, as
prescribed by the Board of Governors of the Federal Reserve System (or any
successor) for determining the maximum reserve requirement for a member bank of

dollars in respect of "Eurocurrency liabilities" (or in respect of any other
category of liabilities which includes deposits by reference to which the
interest rate on Euro-Dollar Loans is determined or any category of extensions
of credit or other assets which includes loans by a non-United States office of
any Bank to United States residents). The Adjusted London Interbank Offered Rate
shall be adjusted automatically on and as of the effective date of any change in
the Euro-Dollar Reserve Percentage.

Period means the average (rounded upward, if necessary, to the next higher 1/16
of 1%) of the respective rates per annum at which deposits in dollars are
offered to the Euro-Dollar Reference Bank in the London interbank market at
approximately 11:00 a.m. (London time) two Euro-Dollar Business Days before the
first day of such Interest Period in an amount approximately equal to the
principal amount of the Euro-Dollar Loan of such Euro-Dollar Reference Bank to
which such Interest Period is to apply and for a period of time comparable to
such Interest Period.

                  (c) In the event that, and for so long as, any Event of
Default shall have occurred and be continuing, the outstanding principal amount
of the Loans, and, to the extent permitted by law, overdue interest in respect
of all Loans, shall bear interest at the annual rate of the sum of the Prime
Rate and four percent (4%).

                  (d) The Lead Agent shall determine each interest rate
applicable to the Loans hereunder. The Lead Agent shall give prompt notice to
the Borrower and the Banks of each rate of interest so determined, and its
determination thereof shall be conclusive in the absence of manifest error.

                  (e) The Reference Bank agrees to use its best efforts to
furnish quotations to the Lead Agent as contemplated by this Section. If the
Reference Bank does not furnish a timely quotation, the provisions of Section

                                       23
<PAGE>

Margin for Euro-Dollar Loans on the daily average of such issued and undrawn
Letters of Credit, which fee shall be payable, in arrears, on each January 1,
April 1, July 1 and October 1 during the Term. From the occurrence, and during
the continuance, of an Event of Default, such fee shall be increased to be equal

Letters of Credit.

                  (c) Fronting Bank Fee. The Borrower shall pay any Fronting

($5,000,000), or an integral multiple of One Million Dollars ($1,000,000) in
excess thereof, by the delivery to the Lead Agent and the Banks of a notice of
cancellation upon at least three (3) Domestic Business Days' notice to Lead
Agent and the Banks, whereupon, in either event, all or such portion of the
Commitments, shall terminate as to the Banks, pro rata on the date set forth in
such notice of cancellation, and, if there are any Loans then outstanding in an
aggregate amount which exceeds the Commitments (after giving effect to any such
reduction), the Borrower shall prepay to the Lead Agent, for the account of the
Banks, as applicable, all or such portion of Loans outstanding on such date in
accordance with the requirements of Sections 2.11(a) and (b). In no event shall
Borrower be permitted to cancel Commitments for which a Letter of Credit has
been issued and is outstanding unless the Borrower returns (or causes to be
returned) such Letter of Credit to the Fronting Bank. The Borrower shall be
permitted to designate in its notice of cancellation which Loans, if any, are to
be prepaid.

                  (f) Upon receipt of a notice of prepayment or cancellation or
a return of a Letter of Credit pursuant to this Section, the Lead Agent shall
promptly, and in any event within one (1) Domestic Business Day, notify each
Bank of the contents thereof and of such Bank's ratable share (if any) of such
prepayment or cancellation and such notice shall not thereafter be revocable by
the Borrower.

                  (g) Any amounts so prepaid pursuant to this Section 2.11 may
be reborrowed subject to the other terms of this Agreement. In the event the
Borrower elects to cancel all or any portion of the Commitments pursuant to
Section 2.11(e) hereof, such amounts may not be reborrowed.

                  SECTION 2.12. General Provisions as to Payments.

                  (a) The Borrower shall make each payment of principal of, and
interest on, the Loans and of fees hereunder, not later than 12:00 Noon (New
York City time) on the date when due, in Federal or other funds immediately
available in New York City, to the Lead Agent at its address referred to in
Section 9.1. The Lead Agent will distribute to each Bank its ratable share of
each such payment received by the Lead Agent for the account of the Banks on the
same day as received by the Lead Agent if received by the Lead Agent by 3:00
p.m. (New York City time), or, if received by the Lead Agent after 3:00 p.m.
(New York City time), on the immediately following Domestic Business Day.
Whenever any payment of principal of, or interest on, the Base Rate Loans or of
fees shall be due on a day which is not a Domestic Business Day, the date for
payment thereof shall be extended to the next succeeding Domestic Business Day.
Whenever any payment of principal of, or interest on, the Euro-Dollar Loans
shall be due on a day which is not a Euro-Dollar Business Day, the date for
payment thereof shall be extended to the next succeeding Euro-Dollar Business
Day unless such Euro-Dollar Business Day falls in another calendar month, in
which case the date for payment thereof shall be the next preceding Euro-Dollar
Business Day. If the date for any payment of principal is extended by operation
of law or otherwise, interest thereon shall be payable for such extended time.

                  (b) Unless the Lead Agent shall have received notice from the
Borrower prior to the date on which any payment is due to the Banks hereunder
that the Borrower will not make such payment in full, the Lead Agent may assume
that the Borrower has made such payment in full to the Lead Agent on such date
and the Lead Agent may, in reliance upon such assumption, cause to be
distributed to each Bank on such due date an amount equal to the amount then due
such Bank. If and to the extent that the Borrower shall not have so made such
payment, each Bank shall repay to the Lead Agent forthwith on demand such amount
distributed to such Bank together with interest thereon, for each day from the
date such amount is distributed to such Bank until the date such Bank repays
such amount to the Lead Agent, at the Federal Funds Rate.

                                       26

         SECTION 2.13. Funding Losses. If the Borrower makes any payment of
principal with respect to any Euro-Dollar Loan (pursuant to Article II, VI or
VIII or otherwise) on any day other than the last day of the Interest Period
applicable thereto, or the last day of an applicable period fixed pursuant to
Section 2.7(b), or if the Borrower fails to borrow any Euro-Dollar Loans, after
notice has been given to any Bank in accordance with Section 2.4(a), the
Borrower shall reimburse each Bank within 15 days after demand for any resulting
loss or expense incurred by it (or by an existing Participant in the related
Loan), including (without limitation) any loss incurred in obtaining,
liquidating or employing deposits from third parties, but excluding loss of
margin for the period after any such payment or failure to borrow, provided that
such Bank shall have delivered to the Borrower a certificate as to the amount of
such loss or expense and the calculation thereof, which certificate shall be
conclusive in the absence of manifest error.

         SECTION 2.14. Computation of Interest and Fees. Interest based on the
Prime Rate hereunder shall be computed on the basis of a year of 365 days (or
366 days in a leap year) and paid for the actual number of days elapsed
(including the first day but excluding the last day). All other interest and
fees shall be computed on the basis of a year of 360 days and paid for the
actual number of days elapsed (including the first day but excluding the last
day).

         SECTION 2.15. Method of Electing Interest Rates.

         (a) The Loans included in each Borrowing shall bear interest initially
at the type of rate specified by the Borrower in the applicable Notice of
Borrowing. Thereafter, the Borrower may from time to time elect to change or
continue the type of interest rate borne by each Group of Loans (subject in each
case to the provisions of Article VIII), as follows:

                  (i) if such Loans are Base Rate Loans, the Borrower may elect
to convert such Loans to Euro-Dollar Loans as of any Euro-Dollar Business Day;

                  (ii) if such Loans are Euro-Dollar Loans, the Borrower may
elect to convert such Loans to Base Rate Loans or elect to continue such Loans
as Euro-Dollar Loans for an additional Interest Period, in each case effective
on the last day of the then current Interest Period applicable to such Loans.

                                       27
<PAGE>

Each such election shall be made by delivering a notice (a "Notice of Interest
Rate Election") to the Lead Agent at least three (3) Euro-Dollar Business Days
before the conversion or continuation selected in such notice is to be effective
(unless the relevant Loans are to be continued as Base Rate Loans, in which case
such notice shall be delivered to the Lead Agent no later than 12:00 Noon (New
York City time) at least one (1) Domestic Business Day before such continuation
is to be effective). A Notice of Interest Rate Election may, if it so specifies,
apply to only a portion of the aggregate principal amount of the relevant Group
of Loans; provided that (i) such portion is allocated ratably among the Loans
comprising such Group, (ii) the portion to which such notice applies, and the
remaining portion to which it does not apply, are each $1,000,000 or any larger
multiple of $1,000,000, (iii) subject to Section 2.1, there shall be no more
than fifteen (15) Borrowings comprised of Euro-Dollar Loans outstanding at any
time under this Agreement, (iv) no Loan may be continued as, or converted into,
a Euro-Dollar Loan when any Event of Default has occurred and is continuing, and
(v) no Interest Period shall extend beyond the Maturity Date.

         (b)  Each Notice of Interest Rate Election shall specify:

                  (i) the Group of Loans (or portion thereof) to which such
notice applies;

                  (ii) the date on which the conversion or continuation selected
in such notice is to be effective, which shall comply with the applicable clause
of subsection (a) above;

                  (iii) if the Loans comprising such Group are to be converted,
the new type of Loans and, if such new Loans are Euro-Dollar Loans, the duration
of the initial Interest Period applicable thereto; and

                  (iv) if such Loans are to be continued as Euro-Dollar Loans
for an additional Interest Period, the duration of such additional Interest
Period.

Each Interest Period specified in a Notice of Interest Rate Election shall
comply with the provisions of the definition of Interest Period.

         (c) Upon receipt of a Notice of Interest Rate Election from the
Borrower pursuant to subsection (a) above, the Lead Agent shall notify each Bank
on the same day as it receives such Notice of Interest Rate Election of the
contents thereof and such notice shall not thereafter be revocable by the
Borrower. If the Borrower fails to deliver a timely Notice of Interest Rate
Election to the Lead Agent for any Group of Euro-Dollar Loans, such Loans shall
be converted into Base Rate Loans on the last day of the then current Interest
Period applicable thereto.

                  SECTION 2.16. Letters of Credit. (a) Subject to the terms
contained in this Agreement and the other Loan Documents, upon the receipt of a
notice in accordance with Section 2.2(b) requesting the issuance of a Letter of
Credit, the Fronting Bank shall issue a Letter of Credit or Letters of Credit in
such form as is reasonably acceptable to the Borrower in an amount or amounts
equal to the amount or amounts requested by the Borrower.

                  (b) Each Letter of Credit shall be issued in the minimum
amount of Ten Thousand Dollars ($10,000).

                  (c) The Letter of Credit Usage shall be no more than Twenty
Million Dollars ($20,000,000) at any one time.

                  (d) There shall be no more than twenty-five (25) Letters of
Credit outstanding at any one time.

                  (e) In the event of any request for a drawing under any Letter
of Credit by the beneficiary thereunder, the Fronting Bank shall notify the
Borrower and the Lead Agent (and the Lead Agent shall endeavor to notify each
Bank thereof) on or before the date on which the Fronting Bank intends to honor
such drawing, and, except as provided in this subsection (e), the Borrower shall
reimburse the Fronting Bank, in immediately available funds, on the same day on
which such drawing is honored in an amount equal to the amount of such drawing.
Notwithstanding anything contained herein to the contrary, however, unless the
Borrower shall have notified the Lead Agent, and the Fronting Bank prior to
11:00 a.m. (New York time) on the Domestic Business Day immediately prior to the
date of such drawing that the Borrower intends to reimburse the Fronting Bank
for the amount of such drawing with funds other than the proceeds of the Loans,
the Borrower shall be deemed to have timely given a Notice of Borrowing pursuant
to Section 2.2 to the Lead Agent, requesting a Borrowing of Base Rate Loans on
the date on which such drawing is honored and in an amount equal to the amount
of such drawing. Each Bank (other than the Fronting Bank) shall, in accordance
with Section 2.4(b), make available its share of such Borrowing to the Lead
Agent, the proceeds of which shall be applied directly by the Lead Agent to

                                       29
<PAGE>

reimburse the Fronting Bank for the amount of such draw. In the event that any
such Bank fails to make available to the Fronting Bank the amount of such Bank's
participation on the date of a drawing, the Fronting Bank shall be entitled to
recover such amount on demand from such Bank together with interest at the
Federal Funds Rate commencing on the date such drawing is honored.

                  (f) If, after the date hereof, any change in any law or
regulation or in the interpretation thereof by any court or administrative or
governmental authority charged with the administration thereof shall either (a)
impose, modify or deem applicable any reserve, special deposit or similar
requirement against letters of credit issued by, or assets held by, or deposits
in or for the account of, or participations in any letter of credit, upon any
Bank (including the Fronting Bank) or (b) impose on any Bank any other condition
regarding this Agreement or such Bank (including the Fronting Bank) as it
pertains to the Letters of Credit or any participation therein and the result of
any event referred to in the preceding clause (a) or (b) shall be to increase
the cost to the Fronting Bank or any Bank of issuing or maintaining any Letter
of Credit or participating therein then the Borrower shall pay to the Fronting
Bank or such Bank, within 15 days after written demand by such Bank (with a copy
to the Lead Agent), which demand shall be accompanied by a certificate showing,
in reasonable detail, the calculation of such amount or amounts, such additional
amounts as shall be required to compensate the Fronting Bank or such Bank for
such increased costs or reduction in amounts received or receivable hereunder
together with interest thereon at the Base Rate. The amount specified in the
written demand shall, absent manifest error, be final and conclusive and binding
upon the Borrower.

                  (g) The Borrower hereby agrees to protect, indemnify, pay and
save the Fronting Bank harmless from and against any and all claims, demands,
liabilities, damages, losses, costs, charges and expenses (including reasonable
attorneys' fees and disbursements) which the Fronting Bank may incur or be
subject to as a result of (i) the issuance of the Letters of Credit, other than
as a result of the gross negligence or wilful misconduct of the Fronting Bank or
(ii) the failure of the Fronting Bank to honor a drawing under any Letter of
Credit as a result of any act or omission, whether rightful or wrongful, of any
present or future de jure or de facto government or governmental authority
(collectively, "Governmental Acts"), other than as a result of the gross
negligence or wilful misconduct of the Fronting Bank. As between the Borrower
and the Fronting Bank, the Borrower assumes all risks of the acts and omissions
of, or misuses of, the Letters of Credit issued by the Fronting Bank, by the
beneficiaries of such Letters of Credit. In furtherance and not in limitation of


                                       30
<PAGE>

the foregoing, the Fronting Bank shall not be responsible (i) for the form,
validity, sufficiency, accuracy, genuineness or legal effect of any document
submitted by any party in connection with the application for and issuance of
such Letters of Credit, even if it should in fact prove to be in any and all
respects invalid, insufficient, inaccurate, fraudulent or forged; (ii) for the
validity or insufficiency of any instrument transferring or assigning or
purporting to transfer or assign any such Letter of Credit or the rights or
benefits thereunder or proceeds thereof, in whole or in part, which may prove to
be invalid or ineffective for any reason; (iii) for failure of the beneficiary
of any such Letter of Credit to comply fully with conditions required in order
to draw upon such Letter of Credit; (iv) for errors, omissions, interruptions or
delays in transmission or delivery of any message, by mail, cable, telegraph,
telex, facsimile transmission, or otherwise; (v) for errors in interpretation of
any technical terms; (vi) for any loss or delay in the transmission or otherwise
of any documents required in order to make a drawing under any such Letter of
Credit or of the proceeds thereof; (vii) for the misapplication by the
beneficiary of any such Letter of Credit of the proceeds of such Letter of
Credit; and (viii) for any consequence arising from causes beyond the control of
the Fronting Bank, including any Government Acts, in each case other than as a
result of the gross negligence or willful misconduct of the Fronting Bank. None
of the above shall affect, impair or prevent the vesting of the Fronting Bank's
rights and powers hereunder. In furtherance and extension and not in limitation
of the specific provisions hereinabove set forth, any action taken or omitted by
the Fronting Bank under or in connection with the Letters of Credit issued by it
or the related certificates, if taken or omitted in good faith, shall not put
the Fronting Bank under any resulting liability to the Borrower.

                  (h) If the Fronting Bank or the Lead Agent is required at any
time, pursuant to any bankruptcy, insolvency, liquidation or reorganization law
or otherwise, to return to the Borrower any reimbursement by the Borrower of any
drawing under any Letter of Credit, each Bank shall pay to the Fronting Bank or
the Lead Agent, as the case may be, its share of such payment, but without
interest thereon unless the Fronting Bank or the Lead Agent is required to pay
interest on such amounts to the person recovering such payment, in which case
with interest thereon, computed at the same rate, and on the same basis, as the
interest that the Fronting Bank or the Lead Agent is required to pay.

payment in full of all obligations hereunder in respect of any Letter of Credit
or any agreement or instrument relating to any Letter of Credit, whether or not
similar to any of the foregoing, that might otherwise constitute a defense
available to, or a discharge of, the Borrower; provided that such other
circumstance or happening shall not have been the result of gross negligence or
wilful misconduct of the Fronting Bank.

Document to which it is a party, and each such Loan Document constitutes the
legal, valid and binding obligation of Borrower, enforceable in accordance with
its terms, except as enforceability may be limited by applicable insolvency,
bankruptcy or other laws affecting creditors rights generally, or general
principles of equity, whether such enforceability is considered in a proceeding
in equity or at law.

         SECTION 4.4. Subordination of CarrAmerica Loans. The rights and
remedies of Lead Agent and the Banks granted hereunder are and shall remain
superior to and prior to the rights of CarrAmerica in, to and under the
CarrAmerica Loan and any existing or future loans made by CarrAmerica to
Borrower.

         SECTION 4.5. No Violation. Neither the execution, delivery or
performance by or on behalf of the Borrower of the Loan Documents, nor
compliance by the Borrower with the terms and provisions thereof nor the
consummation of the transactions contemplated by the Loan Documents, (i) will
contravene any applicable provision of any law, statute, rule, regulation,
order, writ, injunction or decree of any court or governmental instrumentality
or (ii) will conflict with or result in any breach of, any of the terms,
covenants, conditions or provisions of, or constitute a default under, or result
in the creation or imposition of (or the obligation to create or impose) any
Lien upon any of the property or assets of the Borrower pursuant to the terms of
any indenture, mortgage, deed of trust, or other agreement or other instrument
to which the Borrower is a party or by which it or any of its property or assets
is bound or to which it is subject or (iii) will cause a default by Borrower
under any organizational document of any Subsidiary, or cause a default under
Borrower's articles of incorporation or by-laws.

         SECTION 4.6. Financial Information.

         (a) The unaudited consolidated balance sheet of Borrower as of June 30,
1998, and unaudited consolidated income statements for the three months ended
June 30, 1998, copies of which have been delivered to the Lead Agent, fairly
presents, in conformity with generally accepted accounting principles, the
consolidated financial position of Borrower as of such date and its consolidated
results of operations for such fiscal quarter.

         (b) Since June 30, 1998, (i) there has been no material adverse change
in the business, financial position or results of operations of the Borrower and
(ii) except as previously disclosed to the Lead Agent or as publicly disclosed,
the Borrower has not incurred any material indebtedness or guaranty.

         SECTION 4.7. Litigation.

         (a) There is no action, suit or proceeding pending against, or to the
knowledge of the Borrower, threatened against or affecting, (i) the


                                       38
<PAGE>

Borrower or any of its Subsidiaries, (ii) the Loan Documents or any of the
transactions contemplated by the Loan Documents or (iii) any of their assets, in
any case before any court or arbitrator or any governmental body, agency or
official in which there is a reasonable likelihood of an adverse decision which
could, individually or in the aggregate, have a Material Adverse Effect or which
in any manner draws into question the validity of this Agreement or the other
Loan Documents.

         (b) There are no final nonappealable judgments or decrees in an
aggregate amount of Five Million Dollars ($5,000,000) or more entered by a court
or courts of competent jurisdiction against the Borrower (other than any
judgment as to which, and only to the extent, a reputable insurance company has
acknowledged coverage of such claim in writing).

         SECTION 4.8. Compliance with ERISA.

         (a) Except as previously disclosed to the Lead Agent in writing, each
member of the ERISA Group has fulfilled its obligations under the minimum
funding standards of ERISA and the Internal Revenue Code with respect to each
Plan and is in compliance in all material respects with the presently applicable
provisions of ERISA and the Internal Revenue Code with respect to each Plan,
except where failure to do so would not result in a Material Adverse Effect. No
member of the ERISA Group has (i) sought a waiver of the minimum funding
standard under Section 412 of the Internal Revenue Code in respect of any Plan,
(ii) failed to make any contribution or payment to any Plan or Multiemployer
Plan or in respect of any Benefit Arrangement, or made any amendment to any Plan
or Benefit Arrangement, which has resulted or could result in the imposition of
a Lien or the posting of a bond or other security under ERISA or the Internal
Revenue Code or (iii) incurred any liability under Title IV of ERISA other than
a liability to the PBGC for premiums under Section 4007 of ERISA.

         (b) The transactions contemplated by the Loan Documents will not
constitute a nonexempt prohibited transaction (as such term is defined in
Section 4975 of the Code or Section 406 of ERISA) that could subject the Lead
Agent or the Banks to any tax or penalty or prohibited transactions imposed
under Section 4975 of the Code or Section 502(i) of ERISA.

         SECTION 4.9. Intentionally Omitted.

subsidiaries have each filed all United States Federal income tax returns and
all other material tax returns which are required to be filed by them and have
paid all taxes due pursuant to such returns or pursuant to any assessment
received by the Borrower. The charges, accruals and reserves on the books of the
Borrower and its subsidiaries in respect of taxes or other governmental charges
are, in the opinion of the Borrower, adequate.

         SECTION 4.11. Full Disclosure. All information heretofore furnished by
the Borrower to the Lead Agent or any Bank for purposes of or in connection with
this Agreement or any transaction contemplated hereby is true and accurate in
all material respects on the date as of which such information is stated or
certified. The Borrower has disclosed to the Banks in writing any and all facts
known to the Borrower which materially and adversely affect or are likely to
materially and adversely affect (to the extent the Borrower can now reasonably
foresee), the business, operations or financial condition of the Borrower and
its subsidiaries considered as one enterprise or the ability of the Borrower to
perform its obligations under this Agreement or the other Loan Documents.

         SECTION 4.12. Solvency . On the Closing Date and after giving effect to
the transactions contemplated by the Loan Documents occurring on the Closing
Date, the Borrower is Solvent.

         SECTION 4.13. Use of Proceeds; Margin Regulations. All proceeds of the
Loans will be used by the Borrower only in accordance with the provisions
hereof. No part of the proceeds of any Loan will be used by the Borrower to
purchase or carry any Margin Stock or to extend credit to others for the purpose
of purchasing or carrying any Margin Stock. Neither the making of any Loan nor
the use of the proceeds thereof will violate or be inconsistent with the
provisions of Regulations T, U or X of the Federal Reserve Board.

         SECTION 4.14. Governmental Approvals. No order, consent, approval,
license, authorization, or validation of, or filing, recording or registration
with, or exemption by, any governmental or public body or authority, or any
subdivision thereof, is required to authorize, or is required in connection with
the execution, delivery and performance of any Loan Document or the consummation
of any of the transactions contemplated thereby other than those that have
already been duly made or obtained and remain in full force and effect.

                                       40
<PAGE>

         SECTION 4.15. Investment Company Act; Public Utility Holding Company
Act. Borrower is not (x) an "investment company" or a company "controlled" by
an "investment company", within the meaning of the Investment Company Act of
1940, as amended, (y) a "holding company" or a "subsidiary company" of a
"holding company" or an "affiliate" of either a "holding company" or a
"subsidiary company" within the meaning of the Public Utility Holding Company
Act of 1935, as amended, or (z) subject to any other federal or state law or
regulation which purports to restrict or regulate its ability to borrow money.

         SECTION 4.16. Closing Date Transactions. On the Closing Date and
immediately prior to the making of the Loans, the transactions (other than the
making of the Loans) intended to be consummated on the Closing Date will have
been consummated in accordance with all applicable laws. All consents and
approvals of, and all other actions by, any Person required in order to make or
consummate such transactions have been obtained, given or taken and are in full
force and effect.

         SECTION 4.17. Representations and Warranties in Loan Documents. All
representations and warranties made by the Borrower in the Loan Documents are
true and correct in all material respects.

         SECTION 4.18. Patents, Trademarks, etc. The Borrower has obtained and
holds in full force and effect all patents, trademarks, service marks, trade
names, copyrights and other such rights or licenses to utilize such patents,
trademarks, service marks, trade names, copyrights and other such rights, free
from burdensome restrictions, which are necessary for the operation of its
business as presently conducted, the impairment of which is likely to have a
Material Adverse Effect. To the Borrower's knowledge, no material product,
process, method, substance, part or other material presently sold by or employed
by the Borrower in connection with such business infringes any patent,
trademark, service mark, trade name, copyright, license or other such right
owned by any other Person. There is not pending or, to the Borrower's knowledge,
threatened any claim or litigation against or affecting Borrower contesting its
right to sell or use any such product, process, method, substance, part or other
material.

         SECTION 4.19. No Default. No Default or Event of Default exists under
or with respect to any Loan Document. Borrower is not in default in any material
respect beyond any applicable grace period under or with respect to any other

                                       41
<PAGE>

material agreement, instrument or undertaking to which it is a party or by which
it or any of its property is bound in any respect, the existence of which
default is likely (to the extent that the Borrower can now reasonably foresee)
to result in a Material Adverse Effect.

         SECTION 4.20. Licenses, etc. The Borrower has obtained and holds in
full force and effect, all franchises, licenses, permits, certificates,
authorizations, qualifications, accreditations, easements, rights of way and
other consents and approvals which are necessary for the operation of its
businesses as presently conducted, the absence of which is likely (to the extent
the Borrower can now reasonably foresee) to have a Material Adverse Effect.

         SECTION 4.21. Compliance With Law. The Borrower is in compliance with
all laws, rules, regulations, orders, judgments, writs and decrees, including,
without limitation, all building and zoning ordinances and codes, the failure to
comply with which is likely (to the extent the Borrower can now reasonably
foresee) to have a Material Adverse Effect.

         SECTION 4.22. No Burdensome Restrictions. The Borrower is not a party
to any agreement or instrument or subject to any other obligation or any charter
or corporate or partnership restriction, as the case may be, which, individually
or in the aggregate, is likely (to the extent the Borrower can now reasonably
foresee) to have a Material Adverse Effect.

         SECTION 4.23. Brokers' Fees. The Borrower has not dealt with any
broker or finder with respect to the transactions contemplated by the Loan
Documents (except with respect to the acquisition or disposition of Lease
Assets) or otherwise in connection with this Agreement, and Borrower has not
done any acts, had any negotiations or conversation, or made any agreements or
promises which will in any way create or give rise to any obligation or
liability for the payment by the Borrower of any brokerage fee, charge,
commission or other compensation to any party with respect to the transactions
contemplated by the Loan Documents (except with respect to the acquisition or
disposition of Lease Assets), other than the fees payable hereunder.

         SECTION 4.24. Labor Matters. There are no collective bargaining
agreements or Multiemployer Plans covering the employees of the Borrower and the
Borrower has not suffered any strikes, walkouts, work stoppages or other
material labor difficulty within the last five (5) years.

<PAGE>

         SECTION 4.25. Organizational Documents. The documents delivered
pursuant to Section 3.1(e) constitute, as of the Closing Date, all of the
organizational documents (together with all amendments and modifications
thereof) of the Borrower. The Borrower represents that it has delivered to the
Lead Agent true, correct and complete copies of each of the documents set forth
in this Section 4.25.

         SECTION 4.26. Principal Offices. The principal office, chief executive
office and principal place of business of the Borrower is 1117 Perimeter Center
West, Suite 500 East, Atlanta, Georgia 30338.

         SECTION 4.27. Subordination of CarrAmerica Loan. Subject to the
provisions of Section 5.8(a), the CarrAmerica Loan and all other obligations or
liabilities of Borrower to CarrAmerica have been subordinated, by their terms,
to this Facility and all of CarrAmerica's rights and interests in and to the
collateral for the CarrAmerica Loan have been subordinated by their terms to
this Facility.

         SECTION 4.28. Ownership of Property. The Borrower's interest in real
property is limited to the Lease Assets. The Borrower has not owned and does not
intend to own any fee simple or groundleasehold interests in real property.
Schedule 4.28 attached hereto and made a part hereof sets forth all the real
property leased by the Borrower and Persons in which the Borrower, directly or
indirectly, owns an interest as of the Closing Date. As of the Closing Date, the
Borrower and such Persons have good and insurable leasehold title to all of such
real property, subject to customary encumbrances and liens as of the date of
this Agreement. As of the date of this Agreement, there are no mortgages, deeds
of trust, indentures, debt instruments or other agreements creating a Lien
against any of the Lease Assets except as disclosed on Schedule 4.28.

         SECTION 4.29. Insurance. The Borrower currently maintains, or causes
its tenants to maintain, insurance at 100% replacement cost insurance coverage
(subject to customary deductibles) in respect of each of the Lease Assets, as
well as commercial general liability insurance (including "builders' risk")
against claims for personal, and bodily injury and/or death, to one or more
persons, or property damage, as well as workers' compensation insurance, in each
case with respect to the Lease Assets with insurers having an A.M. Best
policyholders' rating of not less than A-IX in amounts that prudent owner of
assets such as the Lease Assets would maintain.

<PAGE>

         SECTION 4.30. Year 2000 Compliance. The Borrower has conducted a
comprehensive review and assesment of its computer applications and has made
such inquiry as it determined to be advisable of its key suppliers, vendors and
customers or prospects with respect to the "year 2000 problem" (i.e., the risk
that computer applications may not be able to properly perform date-sensitive
functions after December 31, 1999) and, based on that review and inquiry, the
Borrower does not believe that the year 2000 problem will result in a material
adverse change in its business condition (financial or otherwise), operations,
properties or prospects, or ability to repay the Loans.


                                    ARTICLE V

                       AFFIRMATIVE AND NEGATIVE COVENANTS

<PAGE>

tax liabilities may be contested in good faith by appropriate proceedings, and

and any and all accrued interest on, the Loans and any and all accrued fees and
other Obligations hereunder shall automatically become immediately due and
payable, with all additional interest from time to time accrued thereon and
without presentation, demand, or protest or other requirements of any kind


                                       53
<PAGE>

(including, without limitation, valuation and appraisement, diligence,
presentment, notice of intent to demand or accelerate and notice of
acceleration), all of which are hereby expressly waived by the Borrower; and
upon the occurrence and during the continuance of any other Event of Default,
the Lead Agent may exercise any of its rights and remedies hereunder and by
written notice to the Borrower, declare the unpaid principal amount of and any
and all accrued and unpaid interest on the Loans and any and all accrued fees
and other Obligations hereunder to be, and the same shall thereupon be,
immediately due and payable with all additional interest from time to time

requirements of any kind other than as provided in the Loan Documents
(including, without limitation, valuation and appraisement, diligence,
presentment, and notice of intent to demand or accelerate), all of which are
hereby expressly waived by the Borrower.

         (b) Notwithstanding the foregoing, upon the occurrence and during the

remedies hereunder nor declare the unpaid principal amount of and any and all
accrued and unpaid interest on the Loans and any and all accrued fees and other
Obligations hereunder to be immediately due and payable, until such time as the
Lead Agent shall have delivered a notice to the Banks specifying the Event of
Default which has occurred and whether Lead Agent recommends the acceleration of
the Obligations due hereunder or the exercise of other remedies hereunder. The
Banks shall notify the Lead Agent if they approve or disapprove of the
acceleration of the Obligations due hereunder or the exercise of such other
remedy recommended by Lead Agent within five (5) Domestic Business Days after
receipt of such notice. If any Bank shall not respond within such five (5)
Domestic Business Day period, then such Bank shall be deemed to have accepted
Lead Agent's recommendation for acceleration of the Obligations due hereunder or
the exercise of such other remedy. If the Required Banks shall approve the
acceleration of the Obligations due hereunder or the exercise of such other
remedy, then Lead Agent shall declare the unpaid principal amount of and any and
all accrued and unpaid interest on the Loans and any and all accrued fees and
other Obligations hereunder to be immediately due and payable or exercise such
other remedy approved by the Required Banks. If the Required Banks shall neither
approve nor disapprove the acceleration of the Obligations due hereunder or such
other remedy recommended by Lead Agent, then Lead Agent may accelerate the
Obligations due hereunder or exercise any of its rights and

                                       54
<PAGE>

remedies hereunder in its sole discretion. If the Required Banks shall
disapprove the acceleration of the Obligations due hereunder or the exercise of
such other remedy recommended by Lead Agent, but approve of another remedy, then
to the extent permitted hereunder, Lead Agent shall exercise such remedy.

         SECTION 6.3. Notice of Default. If the Lead Agent shall not already
have given any notice to the Borrower under Section 6.1, the Lead Agent shall
give notice to the Borrower under Section 6.1 promptly upon being requested to
do so by the Required Banks and shall thereupon notify all the Banks thereof.

         SECTION 6.4. Actions in Respect of Letters of Credit. (a) If, at any
time and from time to time, any Letter of Credit shall have been issued
hereunder and an Event of Default shall have occurred and be continuing, then,
upon the occurrence and during the continuation thereof, the Lead Agent may,
whether in addition to the taking by the Lead Agent of any of the actions
described in this Article or otherwise, make a demand upon the Borrower to, and
forthwith upon such demand (but in any event within ten (10) days after such
demand), the Borrower shall, pay to the Lead Agent, on behalf of the Banks, in
same day funds at the Lead Agent's office designated in such demand, for deposit
in a special cash collateral account (the "Letter of Credit Collateral Account")
to be maintained in the name of the Lead Agent (on behalf of the Banks) and
under its sole dominion and control at such place as shall be designated by the
Lead Agent, an amount equal to the amount of the Letter of Credit Usage under
the Letters of Credit. Interest shall accrue on the Letter of Credit Collateral
Account at a rate equal to the rate on overnight funds.

         (b) The Borrower hereby pledges, assigns and grants to the Lead Agent,
as administrative agent for its benefit and the ratable benefit of the Banks a
lien on and a security interest in, the following collateral (the "Letter of
Credit Collateral"):

         (i) the Letter of Credit Collateral Account, all cash deposited therein
and all certificates and instruments, if any, from time to time representing or
evidencing the Letter of Credit Collateral Account;

                                       55
<PAGE>

             (ii) all notes, certificates of deposit and other instruments from
time to time hereafter delivered to or otherwise possessed by the Lead Agent for
or on behalf of the Borrower in substitution for or in respect of any or all of
the then existing Letter of Credit Collateral;

             (iii) all interest, dividends, cash, instruments and other property
from time to time received, receivable or otherwise distributed in respect of or
in exchange for any or all of the then existing Letter of Credit Collateral; and

             (iv) to the extent not covered by the above clauses, all proceeds
of any or all of the foregoing Letter of Credit Collateral.

The lien and security interest granted hereby secures the payment of all
obligations of the Borrower now or hereafter existing hereunder and under any
other Loan Document.

         (c) The Borrower hereby authorizes the Lead Agent for the ratable
benefit of the Banks to apply, from time to time after funds are deposited in
the Letter of Credit Collateral Account, funds then held in the Letter of Credit
Collateral Account to the payment of any amounts, in such order as the Lead
Agent may elect, as shall have become due and payable by the Borrower to the
Banks in respect of the Letters of Credit.

         (d) Neither the Borrower nor any Person claiming or acting on behalf of
or through the Borrower shall have any right to withdraw any of the funds held
in the Letter of Credit Collateral Account, except as provided in Section 6.4(h)
hereof.

         (e) The Borrower agrees that it will not (i) sell or otherwise dispose
of any interest in the Letter of Credit Collateral or (ii) create or permit to
exist any lien, security interest or other charge or encumbrance upon or with
respect to any of the Letter of Credit Collateral, except for the security
interest created by this Section 6.4.

         (f) If any Event of Default shall have occurred and be continuing:

             (i) The Lead Agent may, in its sole discretion, without notice to
the Borrower except as required by law and at any time from time to time,
charge, set off or otherwise apply all or any part of first, (x) amounts


                                       56
<PAGE>

previously drawn on any Letter of Credit that have not been reimbursed by the
Borrower and (y) any Letter of Credit Usage described in clause (ii) of the
definition thereof that are then due and payable and second, any other unpaid
Obligations then due and payable against the Letter of Credit Collateral Account
or any part thereof, in such order as the Lead Agent shall elect. The rights of
the Lead Agent under this Section 6.4 are in addition to any rights and remedies
which any Bank may have.

             (ii) The Lead Agent may also exercise, in its sole discretion, in
respect of the Letter of Credit Collateral Account, in addition to the other
rights and remedies provided herein or otherwise available to it, all the rights
and remedies of a secured party upon default under the Uniform Commercial Code
in effect in the State of New York at that time.

         (g) The Lead Agent shall be deemed to have exercised reasonable care in
the custody and preservation of the Letter of Credit Collateral if the Letter of
Credit Collateral is accorded treatment substantially equal to that which the
Lead Agent accords its own property, it being understood that, assuming such
treatment, the Lead Agent shall not have any responsibility or liability with
respect thereto.

         (h) At such time as all Events of Default have been cured or waived in
writing, all amounts remaining in the Letter of Credit Collateral Account shall
be promptly returned to the Borrower. Absent such cure or written waiver, any
surplus of the funds held in the Letter of Credit Collateral Account and
remaining after payment in full of all of the Obligations of the Borrower
hereunder and under any other Loan Document after the Maturity Date shall be
paid to the Borrower or to whomsoever may be lawfully entitled to receive such
surplus.

of the Borrower as if it were not the Lead Agent hereunder, and the term "Bank"
and "Banks" shall include Morgan in its individual capacity.

         SECTION 7.3. Action by Lead Agent. The obligations of the Lead Agent
hereunder are only those expressly set forth herein. Without limiting the
generality of the foregoing, the Lead Agent shall not be required to take any
action with respect to any Default, except as expressly provided in Article VI.

         SECTION 7.4. Consultation with Experts. The Lead Agent may consult
with legal counsel (who may be counsel for the Borrower), independent public
accountants and other experts selected by it and shall not be liable for any
action taken or omitted to be taken by it in good faith in accordance with the
advice of such counsel, accountants or experts.

         SECTION 7.5. Liability of Lead Agent. Neither the Lead Agent nor any
of its affiliates nor any of their respective directors, officers, agents or
employees shall be liable for any action taken or not taken by it in connection
herewith (i) with the consent or at the request of the Required Banks or, where
required by the terms of this Agreement, all of the Banks, or (ii) in the
absence of its own gross negligence or willful misconduct. Neither the Lead

indemnitees may suffer or incur in connection with this Agreement, the other
Loan Documents or any action taken or omitted by such indemnitees hereunder.

         SECTION 7.7. Credit Decision. Each Bank acknowledges that it has,

taking or not taking any action under this Agreement.

         SECTION 7.8. Successor Lead Agent. The Lead Agent may resign at any
time by giving notice thereof to the Banks and the Borrower. Upon any such

the Required Banks shall have the right to appoint a successor Lead Agent. If no
successor Lead Agent shall have been so appointed by the Required Banks, and

of the Banks, appoint a successor Lead Agent, which shall be a commercial bank
organized or licensed under the laws of the United States of America or of any

                                  ARTICLE VIII

                            CHANGE IN CIRCUMSTANCES


         SECTION 8.1. Basis for Determining Interest Rate Inadequate or Unfair.
If on or prior to the first day of any Interest Period for any Euro-Dollar
Borrowing:

         (a) the Lead Agent is advised by the Reference Bank that deposits in
dollars (in the applicable amounts) are not being offered to the Reference Bank
in the relevant market for such Interest Period, or

         (b) Banks having 50% or more of the aggregate amount of the Commitments
advise the Lead Agent that the Adjusted London Interbank Offered Rate as
determined by the Lead Agent will not adequately and fairly reflect the cost to
such Banks of funding their Euro-Dollar Loans for such Interest Period, the Lead
Agent shall forthwith give notice thereof to the Borrower and the Banks,

                                       60
<PAGE>

whereupon until the Lead Agent notifies the Borrower that the circumstances
giving rise to such suspension no longer exist, the obligations of the Banks to
make Euro-Dollar Loans shall be suspended. Unless the Borrower notifies the Lead
Agent at least two Domestic Business Days before the date of any Euro-Dollar
Borrowing for which a Notice of Borrowing has previously been given that it
elects not to borrow on such date, such Borrowing shall instead be made as a
Base Rate Borrowing.

         SECTION 8.2. Illegality. If, after the date of this Agreement, the
adoption of any applicable law, rule or regulation, or any change in any
existing applicable law, rule or regulation, or any change in the interpretation
or administration thereof by any governmental authority, central bank or
comparable agency charged with the interpretation or administration thereof, or
compliance by any Bank (or its Euro-Dollar Lending Office) with any request or
directive (whether or not having the force of law) of any such authority,
central bank or comparable agency shall make it unlawful or impossible for any
Bank (or its Euro-Dollar Lending Office) to make, maintain or fund its
Euro-Dollar Loans or to participate in any Letter of Credit issued by the
Fronting Bank or, with respect to the Fronting Bank, to issue any Letters of
Credit, and such Bank shall so notify the Lead Agent, the Lead Agent shall
forthwith give notice thereof to the other Banks and the Borrower, whereupon
until such Bank notifies the Borrower and the Lead Agent that the circumstances
giving rise to such suspension no longer exist, the obligation of such Bank to
make Euro-Dollar Loans or to participate in any Letter of Credit issued by the
Fronting Bank or, with respect to the Fronting Bank, to issue any Letters of
Credit, shall be suspended. With respect to Euro-Dollar Loans, before giving any
notice to the Lead Agent pursuant to this Section, such Bank shall designate a
different Euro-Dollar Lending Office if such designation will avoid the need for
giving such notice and will not, in the judgment of such Bank, be otherwise
disadvantageous to such Bank. If such Bank shall determine that it may not
lawfully continue to maintain and fund any of its outstanding Euro-Dollar Loans
to maturity and shall so specify in such notice, the Borrower shall immediately
prepay in full the then outstanding principal amount of each such Euro-Dollar
Loan, together with accrued interest thereon. Concurrently with prepaying each
such Euro-Dollar Loan, the Borrower shall borrow a Base Rate Loan in an equal
principal amount from such Bank (on which interest and principal shall be
payable contemporaneously with the related Euro-Dollar Loans of the other
Banks), and such Bank shall make such a Base Rate Loan.

                                       61
<PAGE>

         SECTION 8.3. Increased Cost and Reduced Return.

         (a) If on or after the date hereof, in the case of any Loan or any
obligation to make Loans the adoption of any applicable law, rule or regulation,
or any change in any applicable law, rule or regulation, or any change in the
interpretation or administration thereof by any governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or compliance by any Bank (or its Applicable Lending Office) with any
request or directive (whether or not having the force of law) of any such
authority, central bank or comparable agency shall impose, modify or deem
applicable any reserve (including, without limitation, any such requirement
imposed by the Board of Governors of the Federal Reserve System (but excluding
with respect to any Euro-Dollar Loan any such requirement reflected in an
applicable Euro-Dollar Reserve Percentage)), special deposit, insurance
assessment or similar requirement against assets of, deposits with or for the
account of, or credit extended by, any Bank (or its Applicable Lending Office)
or shall impose on any Bank (or its Applicable Lending Office) or on the London
interbank market any other condition affecting its Euro-Dollar Loans, its Note,
or its obligation to make Euro-Dollar Loans, and the result of any of the
foregoing is to increase the cost to such Bank (or its Applicable Lending
Office) of making or maintaining any such Loans, or to reduce the amount of any
sum received or receivable by such Bank (or its Applicable Lending Office) under
this Agreement or under its Note with respect thereto, by an amount deemed by
such Bank to be material, then, within 15 days after demand by such Bank (with a
copy to the Lead Agent), which demand shall be accompanied by a certificate
showing, in reasonable detail, the calculation of such amount or amounts, the
Borrower shall pay to such Bank such additional amount or amounts as will
compensate such Bank for such increased cost or reduction.

         (b) If any Bank shall have determined that, after the date hereof, the
adoption of any applicable law, rule or regulation regarding capital adequacy,
or any change in any such law, rule or regulation, or any change in the
interpretation or administration thereof by any governmental authority, central


                                       62

bank or comparable agency charged with the interpretation or administration
thereof, or any request or directive regarding capital adequacy (whether or not
having the force of law) of any such authority, central bank or comparable
agency, has or would have the effect of reducing the rate of return on capital
of such Bank (or its Parent) as a consequence of such Bank's obligations
hereunder to a level below that which such Bank (or its Parent) could have
achieved but for such adoption, change, request or directive (taking into
consideration its policies with respect to capital adequacy) by an amount deemed
by such Bank to be material, then from time to time, within 15 days after demand
by such Bank (with a copy to the Lead Agent), which demand shall be accompanied
by a certificate showing, in reasonable detail, the calculation of such amount
or amounts, the Borrower shall pay to such Bank such additional amount or
amounts as will compensate such Bank (or its Parent) for such reduction.

         (c) Each Bank will promptly notify the Borrower and the Lead Agent of
any event of which it has knowledge, occurring after the date hereof, which will
entitle such Bank to compensation pursuant to this Section and will designate a
different Applicable Lending Office if such designation will avoid the need for,
or reduce the amount of, such compensation and will not, in the judgment of such
Bank, be otherwise disadvantageous to such Bank. A certificate of any Bank
claiming compensation under this Section and setting forth the additional amount
or amounts to be paid to it hereunder shall be conclusive in the absence of
manifest error. In determining such amount, such Bank may use any reasonable
averaging and attribution methods.

         SECTION 8.4. Taxes.

         (a) Any and all payments by the Borrower to or for the account of any
Bank or the Lead Agent hereunder or under any other Loan Document shall be made
free and clear of and without deduction for any and all present or future taxes,
duties, levies, imposts, deductions, charges or withholdings, and all
liabilities with respect thereto, excluding, in the case of each Bank and the
Lead Agent, taxes imposed on its income, and franchise taxes imposed on it, by
the jurisdiction under the laws of which such Bank or the Lead Agent (as the
case may be) is organized or any political subdivision thereof and, in the case
of each Bank, taxes imposed on its income, and franchise or similar taxes
imposed on it, by the jurisdiction of such Bank's Applicable Lending Office or

                                       63
<PAGE>

any political subdivision thereof (and, if different from the jurisdiction of
such Bank's Applicable Lending Office, the jurisdiction of the domicile of its
Loans either established by the Bank pursuant to Section 9.12 or determined by
the applicable taxing authorities) (all such non-excluded taxes, duties, levies,
imposts, deductions, charges, withholdings and liabilities being hereinafter
referred to as "Taxes"). If the Borrower shall be required by law to deduct any
Taxes from or in respect of any sum payable hereunder or under any Note or
Letter of Credit or participation therein to any Bank or the Lead Agent, (i) the
sum payable shall be increased as necessary so that after making all required
deductions (including deductions applicable to additional sums payable under
this Section 8.4) such Bank, the Fronting Bank or the Lead Agent (as the case
may be) receives an amount equal to the sum it would have received had no such
deductions been made, (ii) the Borrower shall make such deductions, (iii) the
Borrower shall pay the full amount deducted to the relevant taxation authority
or other authority in accordance with applicable law and (iv) the Borrower shall
furnish to the Lead Agent, at its address referred to in Section 9.1, the
original or a certified copy of a receipt evidencing payment thereof.

         (b) In addition, the Borrower agrees to pay any present or future stamp
or documentary taxes and any other excise or property taxes, or charges or
similar levies which arise from any payment made hereunder or under any Note or
Letter of Credit or participation therein or from the execution or delivery of,
or otherwise with respect to, this Agreement or any Note (hereinafter referred
to as "Other Taxes").

         (c) The Borrower agrees to indemnify each Bank, the Fronting Bank and
the Lead Agent for the full amount of Taxes or Other Taxes (including, without
limitation, any Taxes or Other Taxes imposed or asserted by any jurisdiction on
amounts payable under this Section 8.4) paid by such Bank, the Fronting Bank or
the Lead Agent (as the case may be) and any liability (including penalties,
interest and expenses) arising therefrom or with respect thereto. This
indemnification shall be made within 15 days from the date such Bank, the
Fronting Bank or the Lead Agent (as the case may be) makes demand therefor.

                                       64
<PAGE>

         (d) Each Bank organized under the laws of a jurisdiction outside the
United States, on or prior to the date of its execution and delivery of this
Agreement in the case of each Bank listed on the signature pages hereof and on
or prior to the date on which it becomes a Bank in the case of each other Bank,
and from time to time thereafter if requested in writing by the Borrower (but
only so long as such Bank remains lawfully able to do so), shall provide the
Borrower with Internal Revenue Service form 1001 or 4224, as appropriate, or any
successor form prescribed by the Internal Revenue Service, certifying that such
Bank is entitled to benefits under an income tax treaty to which the United
States is a party which reduces the rate of withholding tax on payments of
interest or certifying that the income receivable pursuant to this Agreement is
effectively connected with the conduct of a trade or business in the United
States. If the form provided by a Bank at the time such Bank first became a
party to this Agreement or at any time thereafter (other than solely by reason
of a change in United States law or a change in the terms of any treaty to which
the United States is a party after the date hereof) indicates a United States
interest withholding tax rate in excess of zero (or would have indicated such a
withholding tax rate if such form had been submitted and completed accurately
and completely and either was not submitted or was not completed accurately and
completely), or if a Bank otherwise is subject to United States interest
withholding tax at a rate in excess of zero at any time for any reason (other
than solely by reason of a change in United States law or regulation or a change
in any treaty to which the United States is a party after the date hereof),
withholding tax at such rate shall be considered excluded from "Taxes" as
defined in Section 8.4(a). In addition, any amount that otherwise would be
considered "Taxes" or "Other Taxes" for purposes of this Section 8.4 shall be
excluded therefrom if the Bank either has transferred the domicile of its Loans
pursuant to Section 9.12 or changed the Applicable Lending Office with respect
to such Loans and such amount would not have been incurred had such transfer or
change not been made.

         (e) For any period with respect to which a Bank has failed to provide
the Borrower with the appropriate form pursuant to Section 8.4(d) (unless such
failure is due to a change in treaty, law or regulation occurring subsequent to


                                       65
<PAGE>

the date on which a form originally was required to be provided), such Bank
shall not be entitled to indemnification under Section 8.4(a) with respect to
Taxes imposed by the United States; provided, however, that should a Bank, which
is otherwise exempt from or subject to a reduced rate of withholding tax, become
subject to Taxes because of its failure to deliver a form required hereunder,
the Borrower shall take such steps as such Bank shall reasonably request to
assist such Bank to recover such Taxes.

         (f) If the Borrower is required to pay additional amounts to or for the
account of any Bank pursuant to this Section 8.4, then such Bank will change the
jurisdiction of its Applicable Lending Office so as to eliminate or reduce any
such additional payment which may thereafter accrue if such change, in the
judgment of such Bank, is not otherwise disadvantageous to such Bank.

         SECTION 8.5. Base Rate Loans Substituted for Affected Euro-Dollar
Loans. If (i) the obligation of any Bank to make Euro-Dollar Loans has been
suspended pursuant to Sections 8.1 or 8.2 or (ii) any Bank has demanded
compensation under Section 8.3 or 8.4 with respect to its Euro-Dollar Loans and
the Borrower shall, by at least five Euro-Dollar Business Days' prior notice to
such Bank through the Lead Agent, have elected that the provisions of this
Section shall apply to such Bank, then, unless and until such Bank notifies the
Borrower that the circumstances giving rise to such suspension or demand for
compensation no longer exist:

         (a) all Loans which would otherwise be made by such Bank as Euro-Dollar
Loans shall be made instead as Base Rate Loans (on which interest and principal
shall be payable contemporaneously with the related Euro-Dollar Loans of the
other Banks), and

         (b) after each of its Euro-Dollar Loans has been repaid, all payments
of principal which would otherwise be applied to repay such Euro-Dollar Loans
shall be applied to repay its Base Rate Loans instead.

Banks and the Borrower. Each such notice, request or other communication shall
be effective (i) if given by telecopy, when such telecopy is transmitted to the
telecopy number specified in this Section, (ii) if given by mail, 72 hours after
such communication is deposited in the mails with first class postage prepaid,
addressed as aforesaid or (iii) if given by any other means, when delivered at
the address specified in this Section; provided that notices to the Lead Agent
under Article II or Article VIII shall not be effective until received.

         SECTION 9.2. No Waivers. No failure or delay by the Lead Agent or any
Bank in exercising any right, power or privilege hereunder or under any Note
shall operate as a waiver thereof nor shall any single or partial exercise
thereof preclude any other or further exercise thereof or the exercise of any
other right, power or privilege. The rights and remedies herein provided shall
be cumulative and not exclusive of any rights or remedies provided by law.

         SECTION 9.3.  Expenses; Indemnification.

         (a) The Borrower shall pay (i) all reasonable out-of-pocket expenses of
the Lead Agent (including, without limitation, reasonable fees and disbursements
of special counsel Skadden, Arps, Slate, Meagher & Flom, local counsel for the
Lead Agent, and travel expenses), in connection with the preparation and


                                       67
<PAGE>

administration of this Agreement, the Loan Documents and the documents and
instruments referred to therein, the syndication of the Loans, any waiver or
consent hereunder or any amendment or modification hereof or any Default or
alleged Default hereunder and (ii) if an Event of Default occurs, all reasonable
out-of-pocket expenses incurred by the Lead Agent and each Bank, including,
without limitation, reasonable fees and disbursements of counsel for the Lead
Agent, in connection with the enforcement of the Loan Documents and the
instruments referred to therein and such Event of Default and collection,
bankruptcy, insolvency and other enforcement proceedings resulting therefrom.

         (b) The Borrower agrees to indemnify the Lead Agent and each Bank,
their respective affiliates and the respective directors, officers, agents and
employees of the foregoing (each an "Indemnitee") and hold each Indemnitee
harmless from and against any and all liabilities, losses, damages, costs and
expenses of any kind, including, without limitation, the reasonable fees and
disbursements of counsel, which may be incurred by such Indemnitee in connection
with any investigative, administrative or judicial proceeding (whether or not
such Indemnitee shall be designated a party thereto) that may at any time
(including, without limitation, at any time following the payment of the
Obligations) be imposed on, asserted against or incurred by any Indemnitee as a
result of, or arising out of, or in any way related to or by reason of, (i) any
of the transactions contemplated by the Loan Documents or the execution,
delivery or performance of any Loan Document,(ii) the grant to the Lead Agent
and the Banks of any Lien in any property or assets of the Borrower or any stock
or other equity interest in the Borrower, and (iii) the exercise by the Lead
Agent and the Banks of their rights and remedies (including, without limitation,
foreclosure) under any agreements creating any such Lien (but excluding, as to
any Indemnitee, any such losses, liabilities, claims, damages, expenses,
obligations, penalties, actions, judgments, suits, costs or disbursements
incurred solely by reason of (i) the gross negligence or willful misconduct of
such Indemnitee as finally determined by a court of competent jurisdiction and
(ii) any investigative, administrative or judicial proceeding imposed or
asserted against any Indemnitee by any bank regulatory agency or by any equity
holder of such Indemnitee). The Borrower's obligations under this Section shall
survive the termination of this Agreement and the payment of the Obligations.

                                       68
<PAGE>

         (c) The Borrower shall pay, and hold the Lead Agent and each of the
Banks harmless from and against, any and all present and future U.S. stamp,
recording, transfer and other similar foreclosure related taxes with respect to
the foregoing matters and hold the Lead Agent and each Bank harmless from and
against any and all liabilities with respect to or resulting from any delay or
omission (other than to the extent attributable to such Bank) to pay such taxes.

         SECTION 9.4. Sharing of Set-Offs. In addition to any rights now or
hereafter granted under applicable law or otherwise, and not by way of
limitation of any such rights, upon the occurrence and during the continuance of
any Event of Default, each Bank is hereby authorized at any time or from time to
time, without presentment, demand, protest or other notice of any kind to the
Borrower or to any other Person, any such notice being hereby expressly waived,
to set off and to appropriate and apply any and all deposits (general or
special, time or demand, provisional or final), other than deposits held for the
benefit of third parties, and any other indebtedness at any time held or owing
by such Bank (including, without limitation, by branches and agencies of such
Bank wherever located) to or for the credit or the account of the Borrower
against and on account of the Obligations of the Borrower then due and payable
to such Bank under this Agreement or under any of the other Loan Documents,
including, without limitation, all interests in Obligations purchased by such
Bank. Each Bank agrees that if it shall, by exercising any right of set-off or
counterclaim or otherwise, receive payment of a proportion of the aggregate
amount of principal and interest due with respect to any Note held by it or
Letter of Credit participated in by it, or, in the case of the Fronting Bank,
Letter of Credit issued by it, which is greater than the proportion received by
any other Bank or Letter of Credit issued or participated in by such other Bank,
in respect of the aggregate amount of principal and interest due with respect to
any Note held by such other Bank, the Bank receiving such proportionately
greater payment shall purchase such participations in the Notes held by the
other Banks or Letter of Credit issued or participated in by such other Bank,
and such other adjustments shall be made, as may be required so that all such
payments of principal and interest with respect to the Notes held by the Banks
or Letter of Credit issued or participated in by such other Banks shall be

                                       69
<PAGE>

shared by the Banks pro rata; provided that nothing in this Section shall impair
the right of any Bank to exercise any right of set-off or counterclaim it may
have and to apply the amount subject to such exercise to the payment of
indebtedness of the Borrower other than its indebtedness under the Notes. The
Borrower agrees, to the fullest extent it may effectively do so under applicable
law, that any holder of a participation in a Note or Letter of Credit, whether
or not acquired pursuant to the foregoing arrangements, may exercise rights of
set-off or counterclaim and other rights with respect to such participation as
fully as if such holder of a participation were a direct creditor of the
Borrower in the amount of such participation.

         SECTION 9.5. Amendments and Waivers. Any provision of this Agreement,
the Notes, the Letters of Credit or other Loan Documents may be amended or
waived if, but only if, such amendment or waiver is in writing and is signed by
the Borrower and the Required Banks (and, if the rights or duties of the Lead
Agent are affected thereby, by the Lead Agent); provided that no such amendment
or waiver shall, unless signed by all the Banks, (i) increase or decrease the
Commitment of any Bank (except for a ratable decrease in the Commitments of all
Banks) or subject any Bank to any additional obligation, (ii) reduce the
principal of or rate of interest on any Loan or any fees specified herein,
including, without limitation, the waiver of any Default or Event of Default in
the payment of interest, principal or fees hereunder if such waiver would result
in a permanent reduction in the amount or change in the timing of the payment of
interest, principal or fees payable hereunder by the Borrower, unless the
Borrower has cured such Default or Event of Default and paid all amounts,
including any default interest, due hereunder at the time a request for consent
is made by Lead Agent to the Banks to the waiver of any Default or Event of
Default in the payment of interest, principal or fees hereunder, in which event
only the consent of the Required Banks to the waiver of such Default or Event of
Default shall be required, (iii) postpone the date fixed for any payment of
principal of or interest on any Loan or any fees hereunder or for any reduction
or termination of any Commitment, (iv) change the percentage of the Commitments
or of the aggregate unpaid principal amount of the Notes, or the number of
Banks, which shall be required for the Banks or any of them to take any action
under this Section or any other provision of this Agreement, (v) amend, release
or terminate the Guaranty, or (vi) amend the provisions of this Section 9.5.

         SECTION 9.6. Successors and Assigns.

         (a) The provisions of this Agreement shall be binding upon and inure to
the benefit of the parties hereto and their respective successors and assigns,
except that the Borrower may not assign or otherwise transfer any of their
rights under this Agreement or the other Loan Documents without the prior
written consent of all Banks.

         (b) Any Bank may at any time grant to one or more banks or other
institutions (each a "Participant") participating interests in its Commitment or
any or all of its Loans. In the event of any such grant by a Bank of a
participating interest to a Participant, whether or not upon notice to the
Borrower and the Lead Agent, such Bank shall remain responsible for the
performance of its obligations hereunder, and the Borrower and the Lead Agent
shall continue to deal solely and directly with such Bank in connection with
such Bank's rights and obligations under this Agreement. Any agreement pursuant
to which any Bank may grant such a participating interest shall provide that
such Bank shall retain the sole right and responsibility to enforce the
obligations of the Borrower hereunder including, without limitation, the right
to approve any amendment, modification or waiver of any provision of this
Agreement; provided that such participation agreement may provide that such Bank
will not agree to any modification, amendment or waiver of this Agreement
described in clause (i), (ii), (iii) or (iv) of Section 9.5 without the consent
of the Participant. The Borrower agrees that each Participant shall, to the
extent provided in its participation agreement, be entitled to the benefits of
Article VIII with respect to its participating interest. An assignment or other
transfer which is not permitted by subsection (c) or (d) below shall be given
effect for purposes of this Agreement only to the extent of a participating
interest granted in accordance with this subsection (b).

         (c) Any Bank may at any time assign to one or more banks or other
institutions (each an "Assignee") all, or a proportionate part of all, of its
rights and obligations under this Agreement, the Notes and the other Loan
Documents, provided that such Assignee shall assume such rights and obligations,

                                       71
<PAGE>

pursuant to an Assignment and Assumption Agreement in substantially the form of
Exhibit B attached hereto executed by such Assignee and such transferor Bank,
with (and subject to) the consent of the Lead Agent and, provided no Event of
Default shall have occurred and be continuing, the Borrower, which consent shall
not be unreasonably withheld or delayed. Notwithstanding the foregoing, however,
if at any time any Bank shall hold Commitments hereunder that, together with
commitments (the "Carr Commitments") it holds pursuant to the provisions of the
Carr Credit Agreement, exceeds $75,000,000 in the aggregate, then, provided that
the amount such Bank shall desire to assign pursuant to the provisions of this
Section shall be not less than $10,000,000, then no consent of either the Lead
Agent or the Borrowers shall be required until such time as such Bank's
aggregate Commitments and Carr Commitments shall equal or be less than
$75,000,000. Upon execution and delivery of such instrument and payment by such
Assignee to such transferor Bank of an amount equal to the purchase price agreed
between such transferor Bank and such Assignee, such Assignee shall be a Bank
party to this Agreement and shall have all the rights and obligations of a Bank
with a Commitment as set forth in such instrument of assumption, and the
transferor Bank shall be released from its obligations hereunder to a
corresponding extent, and no further consent or action by any party shall be
required. Upon the consummation of any assignment pursuant to this subsection
(c), the transferor Bank, the Lead Agent and the Borrower, if applicable, shall
make appropriate arrangements so that, if required, a new Note or Notes are
issued to the Assignee. In connection with any such assignment, the transferor
Bank shall pay to the Lead Agent an administrative fee for processing such
assignment in the amount of $2,500. If the Assignee is not incorporated under
the laws of the United States of America or a state thereof, it shall deliver to
the Borrower and the Lead Agent certification as to exemption from deduction or
withholding of any United States federal income taxes in accordance with Section
8.4.

         (d) Intentionally omitted.

         (e) Any Bank may at any time assign all or any portion of its rights
under this Agreement and its Note and the Letters of Credit participated in by
such Bank (as a Fronting Bank) or, in the case of the Fronting Bank, issued by
it, to a Federal Reserve Bank. No such assignment shall release the transferor
Bank from its obligations hereunder.

                                       72
<PAGE>

         (f) No Assignee, Participant or other transferee of any Bank's rights
shall be entitled to receive any greater payment under Section 8.3 or 8.4 than
such Bank would have been entitled to receive with respect to the rights
transferred, unless such transfer is made with the Borrower's prior written
consent or by reason of the provisions of Section 8.2, 8.3 or 8.4 requiring such
Bank to designate a different Applicable Lending Office under certain
circumstances or at a time when the circumstances giving rise to such greater
payment did not exist.

         SECTION 9.7. Governing Law; Submission to Jurisdiction.

         (a) THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HEREUNDER AND THEREUNDER SHALL BE CONSTRUED IN
ACCORDANCE WITH AND BE GOVERNED BY THE LAWS OF THE STATE OF NEW YORK (WITHOUT
GIVING EFFECT TO THE PRINCIPLES THEREOF RELATING TO CONFLICTS OF LAW).

         (b) Any legal action or proceeding with respect to this Agreement or
any other Loan Document and any action for enforcement of any judgment in
respect thereof may be brought in the courts of the State of New York or of the
United States of America for the Southern District of New York, and, by
execution and delivery of this Agreement, the Borrower hereby accepts for itself
and in respect of its property, generally and unconditionally, the non-exclusive
jurisdiction of the aforesaid courts and appellate courts from any thereof. The
Borrower irrevocably consents to the service of process out of any of the
aforementioned courts in any such action or proceeding by the hand delivery, or
mailing of copies thereof by registered or certified mail, postage prepaid, to
the Borrower at its address set forth below. The Borrower hereby irrevocably
waives any objection which it may now or hereafter have to the laying of venue
of any of the aforesaid actions or proceedings arising out of or in connection
with this Agreement or any other Loan Document brought in the courts referred to
above and hereby further irrevocably waives and agrees not to plead or claim in
any such court that any such action or proceeding brought in any such court has
been brought in an inconvenient forum. Nothing herein shall affect the right of
the Lead Agent, any Bank or any holder of a Note to serve process in any other
manner permitted by law or to commence legal proceedings or otherwise proceed
against the Borrower in any other jurisdiction.

                                       73
<PAGE>

         SECTION 9.8. Marshalling; Recapture. Neither the Lead Agent nor any
Bank shall be under any obligation to marshall any assets in favor of the
Borrower or any other party or against or in payment of any or all of the
Obligations. To the extent any Bank receives any payment by or on behalf of the
Borrower, which payment or any part thereof is subsequently invalidated,
declared to be fraudulent or preferential, set aside or required to be repaid to
the Borrower or its estate, trustee, receiver, custodian or any other party
under any bankruptcy law, state or federal law, common law or equitable cause,
then to the extent of such payment or repayment, the Obligation or part thereof
which has been paid, reduced or satisfied by the amount so repaid shall be
reinstated by the amount so repaid and shall be included within the liabilities
of the Borrower to such Bank as of the date such initial payment, reduction or
satisfaction occurred.

         SECTION 9.9. Counterparts; Integration; Effectiveness. This Agreement
may be signed in any number of counterparts, each of which shall be an original,
with the same effect as if the signatures thereto and hereto were upon the same
instrument. This Agreement constitutes the entire agreement and understanding
among the parties hereto and supersedes any and all prior agreements and
understandings, oral or written, relating to the subject matter hereof. This
Agreement shall become effective upon receipt by the Lead Agent of counterparts
hereof signed by each of the parties hereto (or, in the case of any party as to
which an executed counterpart shall not have been received, receipt by the Lead
Agent in form satisfactory to it of telegraphic, telex or other written
confirmation from such party of execution of a counterpart hereof by such
party).

         SECTION 9.10. WAIVER OF JURY TRIAL. THE BORROWER AND THE LEAD AGENT
AND THE BANKS HEREBY IRREVOCABLY WAIVE ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY
LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE
TRANSACTIONS CONTEMPLATED HEREBY.

         SECTION 9.11. Survival. All indemnities set forth herein shall survive
the execution and delivery of this Agreement and the other Loan Documents and
the making and repayment of the Loans hereunder.

                                       74
<PAGE>

         SECTION 9.12. Domicile of Loans. Subject to the provisions of Article
VIII, each Bank may transfer and carry its Loans at, to or for the account of
any domestic or foreign branch office, subsidiary or affiliate of such Bank.

         SECTION 9.13. Limitation of Liability. (a) No claim may be made by the
Borrower or any other Person against the Lead Agent or any Bank or the
affiliates, directors, officers, employees, attorneys or agent of any of them
for any consequential or punitive damages in respect of any claim for breach of
contract or any other theory of liability arising out of or related to the
transactions contemplated by this Agreement or by the other Loan Documents, or
any act, omission or event occurring in connection therewith; and each Borrower
hereby waives, releases and agrees not to sue upon any claim for any such
damages, whether or not accrued and whether or not known or suspected to exist
in its favor.

         (b) The Lead Agent or any Bank may look to all the assets of the
Borrower in seeking to enforce the Borrower's liability and obligations
hereunder, and the lien of any judgment against the Borrower and any proceeding
instituted on, under or in connection with any Note or any of the other Loan
Documents shall extend to all property now or hereafter owned by the Borrower.

         SECTION 9.14.  Confidentiality.

         Prior to the occurrence and continuance of an Event of Default and
except in connection with the sale or assignment or potential sale or assignment
of any Bank's Commitment or portion of its Commitment pursuant to Section 9.6,
each Bank agrees that it will use reasonable efforts, consistent with its
customary policies for maintaining information as confidential, not to disclose
without the prior consent of the Borrower (other than to its subsidiaries,
directors, agents, employees, auditors, counsel or other professional
consultants, provided that each such recipient shall either agree to be bound by

- --------
(1) Amount should combine principal together with accrued interest and breakage
    compensation, if any, to be paid by the Assignee, net of any portion of any
    upfront fee to be paid by the Assignor to the Assignee. It may be preferable
    in an appropriate case to specify these amounts generically or by formula
    rather than as a fixed sum.

                     AMENDED AND RESTATED GUARANTY AGREEMENT

                  UNCONDITIONAL AMENDED AND RESTATED GUARANTY OF PAYMENT (this
"Guaranty"), is made as of August 27, 1998 by CARRAMERICA REALTY CORPORATION, a
Maryland corporation ("CarrAmerica" or the "Guarantor"), in favor of MORGAN
GUARANTY TRUST COMPANY OF NEW YORK, as Bank and as Lead Agent for the Banks (the
"Lead Agent") for the benefit of the banks (the "Banks") that are from time to
time parties to that certain Amended and Restated Revolving Credit Agreement
(the "Credit Agreement"), dated of even date herewith among OmniOffices, Inc.
(the "Borrower"), the Lead Agent and the Banks.

                  Capitalized terms not otherwise defined in this Guaranty shall
have the meanings ascribed to them in the Credit Agreement.

W I T N E S S E T H:

                  WHEREAS, pursuant to the terms of the Credit Agreement, the
Borrower has requested that the Banks make a Loan to the Borrower, to be
guaranteed by CarrAmerica and to be evidenced by certain Promissory Notes (the
"Notes"), each dated as of even date herewith, in the aggregate principal amount
of Two Hundred Million Dollars ($200,000,000), payable by the Borrower to the
order of the Banks;

                  WHEREAS, this Guaranty is the "Guaranty" referred to in the
Credit Agreement;

                  WHEREAS, CarrAmerica is the owner of all of the issued and
outstanding nonvoting common stock of the Borrower; and

                  WHEREAS, in order to induce the Lead Agent and the Banks to
make the Loan to the Borrower, and to satisfy one of the conditions contained in
the Credit Agreement with respect thereto, CarrAmerica has agreed to enter into
this Guaranty.

                  NOW THEREFORE, in consideration of the premises and the direct
and indirect benefits to be derived from the making of the Loans by the Banks to
the Borrower, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, CarrAmerica hereby agrees as
follows:



<PAGE>



1.       CarrAmerica, on behalf of itself and its successors and assigns, hereby
         irrevocably, absolutely, and unconditionally guarantees the full and
         punctual payment when due, whether at stated maturity or otherwise, of
         all obligations of the Borrower now or hereafter existing under the
         Notes or under any of the other Loan Documents to which the Borrower is
         a party (such obligations being the "Guaranteed Obligations"), and any
         and all reasonable costs and expenses (including, without limitation,
         reasonable attorneys' fees and disbursements) incurred by the Lead
         Agent in enforcing its rights under this Guaranty.

2.       It is agreed that the obligations of CarrAmerica hereunder are primary
         and this Guaranty shall be enforceable against CarrAmerica and its
         successors and assigns without the necessity for any suit or proceeding
         of any kind or nature whatsoever brought by the Lead Agent against the
         Borrower or its successors or assigns or any other party or against any
         security for the payment and performance of the Guaranteed Obligations
         and, to the extent permitted by applicable law, without the necessity
         of any notice of non-payment or non-observance or of any notice of
         acceptance of this Guaranty or of any notice or demand to which
         CarrAmerica might otherwise be entitled (including, without limitation,
         diligence, presentment, notice of maturity, extension of time, change
         in nature or form of the Guaranteed Obligations, acceptance of further
         security, release of further security, imposition or agreement arrived
         at as to the amount of or the terms of the Guaranteed Obligations,
         notice of adverse change in the Borrower's financial condition and any
         other fact which might materially increase the risk to CarrAmerica),
         all of which CarrAmerica, to the extent permitted by applicable law,
         hereby expressly waives; and, to the extent permitted by applicable
         law, CarrAmerica hereby expressly agrees that the validity of this
         Guaranty and its obligations hereunder shall in no way be terminated,
         affected, diminished, modified or impaired by reason of the assertion
         of, or the failure to assert by the Lead Agent against the Borrower or
         its successors or assigns, any of the rights or remedies reserved to
         the Lead Agent pursuant to the provisions of the Loan Documents.
         CarrAmerica hereby agrees that, to the extent permitted by applicable
         law, any notice or directive given at any time to the Lead Agent which
         is inconsistent with the waiver in the immediately preceding sentence
         shall be void and may be ignored by the Lead Agent, and, in addition,
         may not be pleaded or introduced as evidence in any litigation relating
         to this Guaranty for the reason that such pleading or introduction
         would be at variance with the written terms of this Guaranty, unless
         the Lead Agent has specifically agreed otherwise in writing, signed by
         a duly authorized officer. CarrAmerica specifically acknowledges and
         agrees that the foregoing waivers are of the essence of this
         transaction and that, but for this Guaranty and such waivers, the Lead
         Agent and the Banks would not make the requested Loan to the Borrower.
<PAGE>



3.       To the extent permitted by applicable law, CarrAmerica hereby waives,
         covenants and agrees that it will not at any time insist upon, plead or
         in any manner whatsoever claim or take the benefit or advantage of, any
         and all appraisal, valuation, stay, extension, marshalling-of-assets or
         redemption laws, or right of homestead exemption, whether now or at any
         time hereafter in force, which may delay, prevent or otherwise affect
         its performance of its obligations under, or the enforcement by the
         Lead Agent of, this Guaranty. To the extent permitted by applicable
         law, CarrAmerica further covenants and agrees not to set up or claim
         any defense, counterclaim, offset, set-off or other objection of any
         kind to any action, suit or proceeding in law, equity or otherwise, or
         to any demand or claim that may be instituted or made by the Lead Agent
         other than the defense of the actual timely payment and performance by
         the Borrower of the Guaranteed Obligations hereunder. CarrAmerica
         represents, warrants and agrees that, as of the date hereof, its
         obligations under this Guaranty are not subject to any counterclaims,
         offsets or defenses against the Lead Agent of any kind.

4.       The provisions of this Guaranty are for the benefit of the Lead Agent
         on behalf of the Banks and their successors and permitted assigns, and
         nothing herein contained shall impair as between the Borrower and the
         Lead Agent the obligations of the Borrower under the Loan Documents.

5.       This Guaranty shall be a continuing, unconditional and absolute
         guaranty and, to the extent permitted by applicable law, the liability
         of CarrAmerica hereunder shall in no way be terminated, affected,
         modified, impaired or diminished by reason of the happening, from time
         to time, of any of the following, although without notice or the
         further consent of the Guarantor:

                  (a) any assignment, amendment, modification or waiver of or
         change in any of the terms, covenants, conditions or provisions of any
         of the Guaranteed Obligations or the Loan Documents or the invalidity
         or unenforceability of any of the foregoing; or

                  (b) any extension of time that may be granted by the Lead
         Agent to the Borrower, the Guarantor, or their respective successors or
         assigns; or

                  (c) any action which the Lead Agent may take or fail to take
         under or in respect of any of the Loan Documents or by reason of any
         waiver of, or failure to enforce any of the rights, remedies, powers or
         privileges available to the Lead Agent under this Guaranty or available
         to the Lead Agent at law, in equity or otherwise, or any action on the
         part of the Lead Agent granting indulgence or extension in any form
         whatsoever; or

                  (d) any sale, exchange, release, or other disposition of any
         property pledged, mortgaged or conveyed, or any property in which the
         Lead Agent and/or the Banks have been granted a lien or security
         interest to secure any indebtedness of the Borrower to the Lead Agent
         and/or the Banks; or
<PAGE>



                  (e) any release of any person or entity who may be liable in
         any manner for the payment and collection of any amounts owed by the
         Borrower to the Lead Agent and/or the Banks; or

                  (f) the application of any sums by whomsoever paid or however
         realized to any amounts owing by the Borrower to the Lead Agent and/or
         the Banks under the Loan Documents in such manner as the Lead Agent
         shall determine in its sole discretion; or

                  (g) the Borrower's or the Guarantor's voluntary or involuntary
         liquidation, dissolution, sale of all or substantially all of their
         respective assets and liabilities, appointment of a trustee, receiver,
         liquidator, sequestrator or conservator for all or any part of the
         Borrower's or guarantor's assets, insolvency, bankruptcy, assignment
         for the benefit of creditors, reorganization, arrangement, composition
         or readjustment, or the commencement of other similar proceedings
         affecting the Borrower or any guarantor or any of the assets of any of
         them, including, without limitation, (i) the release or discharge of
         the Borrower or the Guarantor from the payment and performance of their
         respective obligations under any of the Loan Documents by operation of
         law, or (ii) the impairment, limitation or modification of the
         liability of the Borrower or any guarantor in bankruptcy, or of any
         remedy for the enforcement of the Guaranteed Obligations under any of
         the Loan Documents, or the liability of CarrAmerica under this
         Guaranty, resulting from the operation of any present or future
         provisions of the Bankruptcy Code or other present or future federal,
         state or applicable statute or law or from the decision in any court;
         or

                  (h) any improper disposition by the Borrower of the proceeds
         of the Loans, it being acknowledged by CarrAmerica that the Lead Agent
         shall be entitled to honor any request made by the Borrower for a
         disbursement of such proceeds and that the Lead Agent shall have no
         obligation to see the proper disposition by the Borrower of such
         proceeds.
<PAGE>



6.       CarrAmerica hereby agrees that if at any time all or any part of any
         payment at any time received by the Lead Agent from the Borrower under
         any of the Notes or other Loan Documents or from the Guarantor under or
         with respect to this Guaranty is or must be rescinded or returned by
         the Lead Agent for any reason whatsoever (including, without
         limitation, the insolvency, bankruptcy or reorganization of the
         Borrower or CarrAmerica), then the obligations of CarrAmerica hereunder
         shall, to the extent of the payment rescinded or returned, be deemed to
         have continued in existence notwithstanding such previous receipt by
         the Lead Agent, and the obligations of CarrAmerica hereunder shall
         continue to be effective or reinstated, as the case may be, as to such
         payment, as though such previous payment to the Lead Agent had never
         been made.

7.       Until this Guaranty is terminated pursuant to the terms hereof,
         CarrAmerica (i) shall have no right of subrogation against the Borrower
         or any entity comprising same by reason of any payments or acts of
         performance by the such party in compliance with the obligations of a
         "Guarantor" hereunder; (ii) hereby waives any right to enforce any
         remedy which CarrAmerica now or hereafter shall have against the
         Borrower or any entity comprising same by reason of any one or more
         payment or acts of performance in compliance with the obligations of
         the Guarantor hereunder; and (iii) shall subordinate any liability or
         indebtedness of the Borrower or any entity comprising same now or
         hereafter held by CarrAmerica to the obligations of the Borrower under
         the Loan Documents; provided that nothing contained herein shall limit
         the right of CarrAmerica to receive any amount from the Borrower or any
         entity comprising the same that is not prohibited by the terms of the
         Loan Documents.

8.       CarrAmerica hereby represents and warrants to the Lead Agent with the
         knowledge that the Lead Agent is relying upon the same, as follows:

                  (a) as of the date hereof, CarrAmerica is the owner of all of
         the issued and outstanding nonvoting common stock of the Borrower, and
         CarrAmerica is familiar with the financial condition of Borrower;
<PAGE>

                  (b) based upon such relationship, CarrAmerica has determined
         that it is in its best interest to enter into this Guaranty;

                  (c) this Guaranty is necessary and convenient to the conduct,
         promotion and attainment of the business and is in furtherance of the
         business purposes of CarrAmerica;

                  (d) the benefits to be derived by CarrAmerica from the
         Borrower's access to funds made possible by the Loan Documents are at
         least equal to the obligations of CarrAmerica undertaken pursuant to
         this Guaranty;

                  (e) CarrAmerica is solvent and has full corporate power, and
         legal right to enter into this Guaranty and to perform its obligations
         under the terms hereof and (i) CarrAmerica is organized or formed and
         validly existing under the law of the state of its establishment or
         formation, (ii) CarrAmerica has complied with all provisions of
         applicable law in connection with the execution and delivery of this
         Guaranty, and (iii) the person executing this Guaranty on behalf of
         CarrAmerica has all the requisite power and authority to execute and
         deliver this Guaranty; and

                  (f) this Guaranty has been duly executed by CarrAmerica and
         constitutes the legal, valid and binding obligation of the Guarantor,
         enforceable against it in accordance with its terms except as
         enforceability may be limited by applicable insolvency, bankruptcy or
         other laws affecting creditors' rights generally or general principles
         of equity whether such enforceability is considered in a proceeding in
         equity or at law.
<PAGE>



9.       CarrAmerica covenants and agrees that, so long as the Guaranteed
         Obligations remain outstanding:

                  (a) CarrAmerica shall be in compliance with the financial
         covenants set forth in Section 5.8 of the Carr Credit Agreement,
         subject to any applicable grace periods set forth therein;

                  (b) CarrAmerica shall maintain an aggregate investment in the
         Borrower in an amount not less than One Hundred Thirty Million Dollars
         ($130,000,000) except with the prior written consent of Banks having at
         least 66 2/3% of the aggregate amount of the Commitments, or if the
         Commitments shall have been terminated, holding Notes evidencing at
         least 66 2/3% of the aggregate unpaid principal amount of the Loans,
         such consent to be in such Banks' sole discretion;

                  (c) CarrAmerica shall not pledge, transfer, sell or otherwise
         encumber any or all of the stock of the Borrower; and

                  (d) If at any time during the term of the Credit Agreement,
         the Carr Credit Agreement shall be terminated, then, CarrAmerica shall
         nevertheless continue to provide the Lead Agent and the Banks with
         those financial statements and other reporting requirements set forth
         in Section 5.1 of the Carr Credit Agreement.

10.      CarrAmerica and the Lead Agent acknowledge and agree that this Guaranty
         is a guaranty of payment and not of collection and enforcement in

         the Banks from the Borrower under the provisions of any Loan Document.

11.      Subject to the terms and conditions of the Credit Agreement, and only
         in conjunction with a transfer permitted thereunder, the Lead Agent may
         assign any or all of its rights under this Guaranty.

12.      CarrAmerica agrees, upon the written request of the Lead Agent, to
         execute and deliver to the Lead Agent, from time to time, any
         modification or amendment hereto or any additional instruments or
         documents reasonably considered necessary by the Lead Agent or its
         counsel to cause this Guaranty to be, become or remain valid and
         effective in accordance with its terms or in order to implement more
         fully the intent of this Guaranty, provided, that, any such
         modification, amendment, additional instrument or document shall not
         increase its obligations or diminish its rights hereunder and shall be
         reasonably satisfactory as to form to CarrAmerica and to its counsel.

         accordance with the terms hereof.

         Documents contains the entire agreement among the parties with respect
         to the Loans being made to the Borrower simultaneously with the
         execution and delivery hereof, and supersedes all prior agreements
         relating to the Loans and may not be modified, amended, supplemented or
         discharged except by a written agreement signed by CarrAmerica and the
         Lead Agent.

15.      If all or any portion of any provision contained in this Guaranty shall
         be determined to be invalid, illegal or unenforceable in any respect
         for any reason, such provision or portion thereof shall be deemed
         stricken and severed from this Guaranty and the remaining provisions
         and portions thereof shall continue in full force and effect.

17.      This Guaranty shall be binding upon CarrAmerica and its successors and
         assigns and shall inure to the benefit of the Lead Agent and its
         successors and assigns.

18.      The failure of the Lead Agent to enforce any right or remedy hereunder,
         or promptly to enforce any such right or remedy, shall not constitute a
         waiver thereof, nor give rise to any estoppel against the Lead Agent,
         nor excuse CarrAmerica from its obligations hereunder. Any waiver of
         any such right or remedy to be enforceable against the Lead Agent must
         be expressly set forth in a writing signed by the Lead Agent.

19.               (a) THIS GUARANTY AND THE RIGHTS AND OBLIGATIONS OF THE
         PARTIES HEREUNDER SHALL BE CONSTRUED IN ACCORDANCE WITH AND BE GOVERNED
         BY THE LAWS OF THE STATE OF NEW YORK.

                  (b) Any legal action or proceeding with respect to this
         Guaranty and any action for enforcement of any judgment in respect
         thereof may be brought in the courts of the State of New York or of the
         United States of America for the Southern District of New York, and, by
         execution and delivery of this Guaranty, CarrAmerica hereby accepts for
         itself and in respect of its property, generally and unconditionally,
         the non-exclusive jurisdiction of the aforesaid courts and appellate
         courts from any thereof. CarrAmerica irrevocably consents to the
         service of process out of any of the aforementioned courts in any such
         action or proceeding by the mailing of copies thereof by registered or
         certified mail, postage prepaid, with delivery to the address for
         notices set forth herein. CarrAmerica hereby irrevocably waives any
         objection which they may now or hereafter have to the laying of venue
         of any of the aforesaid actions or proceedings arising out of or in
         connection with this Guaranty brought in the courts referred to above
         and hereby further irrevocably waive and agrees not to plead or claim
         in any such court that any such action or proceeding brought in any
         such court has been brought in an inconvenient forum. Nothing herein
         shall affect the right of the Lead Agent to serve process in any other
         manner permitted by law or to commence legal proceedings or otherwise
         proceed against CarrAmerica in any other jurisdiction.
<PAGE>

                  (c) CARRAMERICA AND THE LEAD AGENT EACH HEREBY WAIVES ITS
         RIGHTS TO A JURY TRIAL OF ANY AND ALL CLAIMS OR CAUSES OF ACTION BASED
         UPON OR ARISING OUT OF THIS GUARANTY. IT IS HEREBY ACKNOWLEDGED BY THE
         GUARANTOR THAT THE WAIVER OF A JURY TRIAL IS A MATERIAL INDUCEMENT FOR
         THE LEAD AGENT TO ACCEPT THIS GUARANTY AND THAT THE LOANS MADE BY THE
         BANKS ARE MADE IN RELIANCE UPON SUCH WAIVER. THE GUARANTOR FURTHER
         WARRANT AND REPRESENT THAT SUCH WAIVER HAS BEEN KNOWINGLY AND
         VOLUNTARILY MADE, FOLLOWING CONSULTATION WITH LEGAL COUNSEL. IN THE
         EVENT OF LITIGATION, THIS GUARANTY MAY BE FILED BY THE LEAD AGENT IN
         COURT AS A WRITTEN CONSENT TO A NON-JURY TRIAL.

                  (d) CarrAmerica hereby further covenants and agrees to and
         with the Lead Agent that it may be joined in any action against the
         Borrower in connection with the Loan Documents and that recovery may be
         had against CarrAmerica in such action or in any independent action
         against CarrAmerica (with respect to the Guaranteed Obligations),
         without the Lead Agent first pursuing or exhausting any remedy or claim
         against the Borrower or its successors or assigns.

                  (e) CarrAmerica hereby agrees to pay all expenses (including,
         without limitation, reasonable attorneys' fees and disbursements) which
         may be incurred by the Lead Agent in connection with the enforcement of
         its rights under this Guaranty, whether or not suit is initiated;
         provided, however, that such expenses shall be paid by the Lead Agent
         if a final judgment in favor of CarrAmerica is rendered by a court of
         competent jurisdiction. Moreover, CarrAmerica covenants and agrees to
         indemnify and save the Lead Agent harmless of and from, and defend it
         against, all losses, out-of pocket costs and expenses, liabilities,
         damages or claims arising by reason of the failure of CarrAmerica to
         perform its obligations hereunder.
<PAGE>



20.      Subject to the terms of Section 6 hereof, this Guaranty shall terminate
         and be of no further force or effect upon the full performance and
         payment of the Guaranteed Obligations hereunder (the "Release Date").
         Notwithstanding the foregoing, upon the unanimous consent of the Lead
         Agent and the Banks, this Guaranty may be released prior to the payment
         of the Guaranteed Obligations. CarrAmerica acknowledges that the
         conditions to the release of this Guaranty shall be determined in the
         sole and absolute discretion of the Banks and may include, but not be
         limited to, a change to the Applicable Margin with respect to the
         Loans. Upon termination or release of this Guaranty in accordance with
         the terms hereof, the Lead Agent promptly shall deliver to CarrAmerica
         such documents as CarrAmerica or its counsel may reasonably may request
         in order to evidence such termination.

21.      All of the Lead Agent's rights and remedies under each of the Loan
         Documents or under this Guaranty are intended to be distinct, separate
         and cumulative and no such right or remedy therein or herein mentioned
         is intended to be in exclusion of or a waiver of any other right or
         remedy available to the Lead Agent.

                  IN WITNESS WHEREOF, the undersigned has caused this Guaranty
to be duly executed and delivered as of the date first set forth above.

                                    Title: Chief Financial Officer


                                                                    Exhibit 10.5

                            AMENDMENT AGREEMENT

         AMENDMENT AGREEMENT (the "Amendment Agreement") dated as of July 8,
1998, by and between CarrAmerica Realty Corporation (the "Company") and Merrill
Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"). Reference is made herein
to the Purchase Price Adjustment Agreement dated as of April 2, 1998 by and
between the Company and MLPF&S (the "Adjustment Agreement"). Capitalized terms
not otherwise defined herein shall have the meaning ascribed thereto in the
Adjustment Agreement.

         WHEREAS, Section 5 of the Adjustment Agreement provides, among other
things, that the Company shall deliver the Interim Settlement Amount in Interim
Settlement Shares; and

         WHEREAS, the Company and MLPF&S desire to amend the Adjustment
Agreement so as to allow for the delivery by the Company of the Interim
Settlement Amount in cash, subject to the terms and conditions hereof,

         NOW, THEREFORE, in consideration of the mutual undertakings herein set
forth, the parties, intending to be legally bound, hereby agree as follows:

         1.   Within 5 Business Days following each Reset Date, the Company may
              deliver the Interim Settlement Amount in cash to MLPF&S or its
              agent for deposit in a collateral account at MLPF&S or a custodian
              or depository designated by MLPF&S.

         2.   MLPF&S or its agent may invest the cash so delivered in such of
              the following securities ("Permitted Investments"), and in such
              proportions, as the Company shall specify in its written
              instructions to MLPF&S:

             (i)   direct obligations of the United States of America or any
                   instrumentality thereof for the payment of which the full
                   faith and credit of the United States of America is pledged;
                   and/or

             (ii)  certificates of deposit of banks, trust companies organized
                   under the laws of the United States of America or any state
                   thereof, and having combined capital and surplus of at least
                   $50,000,000; and/or

             (iii) bank accounts, including savings accounts and bank money
                   market accounts, the entire balance of which are insured by
                   the Federal Deposit Insurance Corporation.

              Cash deposited in the collateral account, any unreinvested
              earnings on Permitted Investments and cash distributions on any
              Interim Settlement Shares held in the collateral account, that the
              Company does not direct MLPF&S to invest in Permitted Investments
              will not bear interest.
<PAGE>

         3.   On any Reset Date, if the sum of (i) the cash value of the
              Permitted Investments on such Reset Date, (ii) the amount, if any,
              in Interim Settlement Shares held by MLPF&S (valued at the Closing
              Price on such Reset Date) and (iii) any cash amounts held in the
              collateral account in which such Interim Settlement Shares are
              held exceeds the Interim Settlement Amount on such Reset Date (or
              150% of the Interim Settlement Amount, in the event that MLPF&S
              holds restricted Interim Settlement Shares that are not the
              subject of an Effective Registration Statement), MLPF&S shall
              deliver to the Company within five (5) Business Days following
              such Reset Date the amount of such excess in cash from uninvested
              cash amounts in the collateral account and cash realized upon the
              liquidation of Permitted Investments ("Available Cash"); provided
              that if the amount of such excess exceeds Available Cash, MLPF&S
              shall deliver the balance of such excess to the Company in Interim
              Settlement Shares.

         4.   This Amendment Agreement may be executed in counterparts, each of
              which shall be deemed an original, but all of which shall
              constitute one and the same instrument.

         5.   Except as hereby amended, the Adjustment Agreement shall remain in
              full force and effect.

         6.   This Amendment Agreement shall be governed by, and interpreted in
              accordance with, the laws of the State of New York, all rights and
              remedies being governed by such laws.

<PAGE>



         IN WITNESS WHEREOF, the parties have duly executed and delivered this
Amendment Agreement as of the date first above written.

                               AMENDMENT AGREEMENT

         AMENDMENT AGREEMENT (the "Agreement") dated as of October 5, 1998, by
and between CarrAmerica Realty Corporation (the "Company") and Merrill Lynch,
Pierce, Fenner & Smith Incorporated ("MLPF&S"). Reference is made herein to the
Purchase Agreement and the Purchase Price Adjustment Agreement, each dated as of
April 2, 1998, by and between the Company and MLPF&S (the "Purchase Agreement,"
and the "Adjustment Agreement," respectively) and the Amendment Agreement, dated
as of June, 1998 (the "First Amendment Agreement"), by and between the Company
and the MLPF&S. Capitalized terms not otherwise defined herein shall have the
meaning ascribed thereto in the Adjustment Agreement and the Purchase Agreement.

         WHEREAS, pursuant to Section 5 of the Adjustment Agreement, as amended
by Section 1 of the Amendment Agreement, MLPF&S holds cash collateral of the
Company totaling $39,379,721.01 (the "Cash Collateral") in a collateral account
at MLPF&S (the "Collateral Account"); and

         WHEREAS, the parties desire to provide that (i) the Cash Collateral be
paid to MLPF&S in partial satisfaction of the Company's obligations to MLPF&S
under the Adjustment Agreement, (ii) the Reference Price be reduced to reflect
such payment (iii), subject to the terms and conditions hereof, the Company
deliver the Interim Settlement Amount on a biweekly basis and (iv) the schedule
of Termination Prices and corresponding Percentages of Adjustment Shares in
Section 4.1 of the Adjustment Agreement be revised as set forth herein;

         NOW, THEREFORE, in consideration of the mutual undertakings herein set
forth, the parties intending to be legally bound, hereby agree as follows:

1.   The Company authorizes MLPF&S to transfer the Cash Collateral from the
     Collateral Account to MLPF&S on the date of this Agreement as payment for
     the reduction of the Reference Price.

2.   In order to effect the reduction of the Reference Price, the Distribution
     Amount, as calculated pursuant to Section 1(k) of the Adjustment Agreement,
     shall be deemed to include a distribution of $7.876 per Common Share as of
     the date hereof.

3.   Within three days following October 6, 1998 and within three days following
     each second Tuesday thereafter (or, if any such day is not a Business Day,
     the next Business Day) (each such day a "Biweekly Delivery Date"), until
     the number of Adjustment Shares has been reduced to zero, the Company shall
     deliver the Interim Settlement Amount in cash to MLPF&S for deposit in the
     Collateral Account or, if applicable, MLPF&S shall release any cash in
     excess of the Interim Settlement Amount to the Company; provided however,
     that if the Closing Price on any Exchange Trading is below $21.00, the
     Company shall deliver the Interim Settlement Amount in cash to MLPF&S or,
     if applicable, MLPF&S shall release any cash in excess of the Interim
     Settlement Amount to the Company within three days following each Tuesday
     thereafter (or, if any such day is not a Business Day, the next Business
     Day) (each such day a, "Weekly Delivery Date"), until the Closing Price is
     equal to or greater than the Reference Price for three consecutive Exchange
     Trading Days, in which case the Company shall resume delivery of the
     Interim Settlement Amount on each Biweekly Delivery Date unless and until
     the Closing Price is subsequently below $21.00.

<PAGE>

4.  Solely for purposes of calculation of the Interim Settlement Amount, each
    Biweekly Delivery Date and each Weekly Delivery Date shall be deemed a
    Reset Date.

5.  The schedule of Termination Prices and corresponding Percentages of
    Adjustment Shares to be Settled in Section 4.1 of the Adjustment Agreement
    is hereby amended to read as follows:

    Percentage of Adjustment
      Shares to be Settled                              Termination Price
