PART 1


Item 1.          BUSINESS

THE COMPANY

General

         CarrAmerica Realty Corporation (the "Company") is a fully integrated,
self-administered and self-managed publicly traded real estate investment trust
("REIT") that focuses primarily on the acquisition, development, ownership and
operation of office properties in select suburban growth markets across the
United States. As of March 1, 1998, the Company owned a greater than 50%
interest in a portfolio of 256 operating office properties, and 41 properties
under construction. These 256 operating properties contain an aggregate of
approximately 19.9 million square feet and the 41 properties under construction
will contain approximately 3.7 million square feet. The operating properties
owned by the Company as of December 31, 1997 were 95.9% leased as of that date,
with approximately 1,400 tenants.

         The Company and its predecessor, The Oliver Carr Company ("OCCO"), have
developed, owned and operated office buildings in the Washington, D.C.
metropolitan area for more than 35 years. In November 1995, the Company
announced a strategic alliance with a wholly-owned subsidiary of Security
Capital U.S. Realty (together with Security Capital U.S. Realty, "SC-USREALTY"),
a European real estate operating company which owns strategic positions in
selected real estate companies in the United States. As of February 28, 1998,
SC-USREALTY owned approximately 44.1% of the outstanding common stock of the
Company (39.3% on a fully diluted basis).

         The Company's experienced staff of over 1,200 employees, including
approximately 900 on-site building employees, provides a broad range of real
estate services. The Company's principal executive offices are located at 1700
Pennsylvania Avenue, N.W., Washington, D.C. 20006, and its telephone number is
(202) 624-7500. After July 1, 1998 the Company's principal offices will be
located at 1850 K Street, N.W., Washington, D.C. 20006 and its telephone number
will be (202) 729-7500. The Company's web site can be found at
www.carramerica.com. The Company was organized as a Maryland corporation on July
9, 1992.


Business Strategy

         The Company's primary business objectives are to achieve long-term
sustainable per share cash flow growth and to maximize stockholder value through
a strategy of (i) acquiring, developing, owning and operating office properties
primarily in suburban markets throughout the United States that exhibit strong,
long-term growth characteristics and (ii) maintaining and enhancing a national
operating system that provides corporate users of office space with a mix of
products and services to meet their workplace needs at both the national and
local level. The Company has focused its investments primarily in suburban
markets throughout the United States because it believes that the suburban
markets provide growth oriented companies and their employees with workplace
locations which have lower operating costs, greater convenience and a higher
quality of life than traditional central business district locations.

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


                                       2

<PAGE>


         For each identified target market, the Company has established a set of
general guidelines and physical characteristics to evaluate investment
opportunities. All investment decisions are driven by real estate research,
focusing on variables such as composition of economic base, rate and composition
of job growth and office space supply and demand fundamentals. During 1997, the
Company believes that it met its critical mass threshold in substantially all of
its target markets. By achieving such critical mass, the Company believes that
it is able to better serve its customers' needs, realize certain operating
efficiencies and achieve sustainable long-term per share cash flow growth and
maximize stockholder value.

         As of December 31, 1997 the distribution of the Company's operating
properties (on a rentable square foot basis) was as follows: 38% in its Pacific
region, primarily in suburban Seattle and the California markets of Silicon
Valley, Pleasanton, San Mateo, Orange County, Los Angeles and San Diego; 31% in
its Southeast region, primarily in metropolitan Washington, D.C., suburban
Atlanta and Boca Raton, Florida; 14% in its Mountain region, primarily in
suburban Salt Lake City, southeast Denver and suburban Phoenix; and 17% in its
Central region, primarily in suburban Chicago, suburban Dallas and suburban
Austin. Downtown Washington, D.C., which represented 100% of the Company's
portfolio in 1993, accounted for approximately 13% of the Company's portfolio
(on a rentable square foot basis) as of December 31, 1997.

         Operating Property Acquisitions. In November 1995, the Company
implemented a major initiative to acquire operating office properties in order
to establish the operating platform for its national business strategy. Between
January 1, 1996 and March 1, 1998, the Company acquired 241 operating properties
containing approximately 16.7 million square feet, resulting in an approximate
500% increase in the total square footage of operating properties in which the
Company has a majority interest. These properties were acquired for an aggregate
purchase price of approximately $1.9 billion.

         Development Program. Development of office properties is an
increasingly important component of the Company's growth strategy as attractive
acquisition opportunities diminish due to the influx of capital into the office
property market. The Company believes that long-term investment returns
resulting from properties it develops generally will exceed those from
properties it acquires, and the Company will not assume significantly increased
investment risks. The Company minimizes its development risk by employing
extensively trained and experienced development personnel, by avoiding the
assumption of significant entitlement risk in conjunction with land acquisitions
and by entering into guaranteed maximum price (GMP) construction contracts with
seasoned and credible contractors. Most importantly, the Company carefully
analyzes the supply and demand characteristics of a target market before
commencing inventory development in the market. In general, the Company will
only undertake inventory development (which excludes properties under
construction that have been substantially pre-leased) in markets with strong
real estate fundamentals, and then the Company generally will construct office
buildings attractive to a wide range of office users. The Company's
research-driven development program enables it to tailor its development
activities in each target market, from inventory development, to build-to-suit
projects, to holding land for future development. From January 1, 1997 to March
1, 1998, the Company placed in service nine development properties containing
approximately 780,000 square feet. The total cost of these development
properties was $99.1 million and the Company expects that the first year
stabilized unlevered return of these properties will be 11.7%. In addition, as
of March 1, 1998, the Company had an additional 41 properties under construction
that will contain approximately 3.7 million square feet.

         Investments in Land Held for Future Development. The Company believes
that acquiring land to support future development provides it with a competitive
advantage in responding to customers' needs for office space in markets with low
vacancy rates, barriers to entry for new supplies of office space and increasing
rental rates. The Company also believes that the long-term investment returns
available to it on office properties it develops generally will exceed those of
office property acquisition opportunities currently available to the Company. In
addition to its portfolio of operating properties and projects currently under
development, the Company owned or controlled, as of March 1, 1998, land in 15 of
its target markets that is expected to support future development of up to 5.9
million square feet. The Company believes that acquiring land to support future
development provides it with a competitive advantage in responding to customers'
needs for office space in markets with low vacancy rates.

         National Operating System. As part of its business strategy, the
Company has developed and will continue to enhance a national operating system
to provide nationally coordinated customer service, marketing and development.
The Company's national operating system consists of three components: (i) a
Market Officer Group, currently consisting of 11 market officers focused on
developing and maintaining strong local relationships with the Company's
customers and the brokerage community and identifying investment opportunities
for the Company; (ii) a Corporate Services Group, which is dedicated to
marketing the Company's office space to a targeted list of companies; and 
(iii) a National Development Group, which is responsible for developing office
properties, build-to-suit facilities and business parks. The Company's national
operating system is designed to provide corporate users of office space with a
mix of products and services to meet their workplace needs at both the national
and local levels. The Company believes that through its existing portfolio of
operating properties, property development opportunities and land acquired and
currently held for future development, the Company can generate incremental
demand through the relocation and expansion needs of many of its customers, both
within a single target market and in multiple target markets.

         Market Officer Group. The Market Officer Group currently consists of 11
market officers who cover the 16 target markets in which the Company currently
owns properties. These market officers are responsible for maximizing the
performance of the Company's properties in their markets and ensuring that the
needs of the Company's customers are consistently being met. Because they meet
with the Company's customers on a regular basis, market officers are cognizant
of and responsive to customers' relocation or expansion needs. The market
officers have extensive knowledge of local conditions in their respective
markets and, therefore, are invaluable in identifying attractive investment
opportunities in their markets. In addition, through their contact with
customers, market officers are well positioned to help the Corporate Services
Group identify customers with new build-to-suit and multi-market requirements.

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

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

         Executive Office Suites Business. In August 1997, OmniOffices, Inc.
("OmniOffices"), an affiliate of the Company, acquired substantially all of the
assets of OmniOffices Group, Inc. and its subsidiaries for an aggregate purchase
price of approximately $50 million in cash. These assets included 28 executive
office suite centers containing approximately 1,650 office suites located in 14
markets across the country. In addition, OmniOffices has acquired an additional
10 executive office suite centers, and entered into an agreement to acquire
(subject to certain closing conditions) an additional 22 executive office suite
centers (although there can be no assurance that this pending acquisition will
be consummated), for an aggregate cash investment of approximately $88 million.
These additional 32 executive office suite centers contain approximately 2,300
office suites located primarily in New York City, San Francisco, Chicago, Tampa,
Indianapolis and San Diego, and are operated by the two largest franchisees of
the HQ(R) executive office suite network, the largest operator of executive
suites.

                                       4

<PAGE>
         The "executive office suites" business typically involves leasing
20,000 to 30,000 square feet of an office building from the owner and outfitting
that space with 60-70 individual offices (known as office suites) that are
leased on a relatively short-term basis (i.e., one year or less) to customers
who generally utilize one to three offices at a time. OmniOffices generally
provides these customers with administrative support services (e.g.,
secretarial, duplicating, fax and receptionist services), conference and
training facilities, video conferencing, travel arrangements and catering
arrangements. The Company believes that approximately 60% of the current demand
being generated for executive office suites originates from national and
multi-national companies. The Company believes that this line of business has
significant potential for growth because the demand for executive office suites
is likely to increase as companies seek greater flexibility and alternative
workplace solutions for their staffing and business plan requirements. The
Company believes that its position as the only national office property owner
and operator providing both traditional, long-term office space and (through
OmniOffices) flexible, short-term workplace options provides it with a
competitive advantage in meeting the evolving needs of growing companies.

         OmniOffices expects to continue expanding its operations through a
program encompassing both acquisitions and the creation of new executive office
suite centers. OmniOffices has financed its recent acquisitions primarily
through debt and equity investments by the Company. (In conformance with
limitations under the tax laws relating to REITs, OmniOffices is structured as a
taxable "C" corporation in which the Company owns 95% of the economic interest,
but none of the voting stock.) Because the tax laws relating to REITs limit the
amount of investment by the Company in OmniOffices to 5% of the Company's total
assets (or approximately $150 million), future growth of OmniOffices likely will
be financed through third-party debt financing (some or all of which may be
guaranteed by the Company) or equity investments by others (possibly including
public investors).

         Asset Optimization. As a component of its business strategy, the
Company may dispose of assets that become inconsistent with its long-term
strategic or return objectives or where market conditions for disposition are
favorable. The Company would then redeploy the proceeds of such dispositions
into other office properties (utilizing tax-deferred exchanges where possible).
Consistent with this strategy, during 1997, the Company disposed of seven
properties containing approximately 664,000 square feet for approximately $68
million in value. The Company recognized a gain of $5.4 million in conjunction
with these transactions. In addition, in January 1998, the Company disposed of
an additional property containing 267,000 square feet for approximately $78
million in value, resulting in a gain of $43.8 million. The Company also may
consider disposing of additional properties or interests in properties, some of
which may be significant. The Company, however, has agreed with SC-USREALTY to
use its reasonable efforts to dispose of properties only through tax-deferred
exchanges (and the Company also is subject to other similar restrictions with
respect to certain properties acquired by CarrAmerica Realty, L.P. and Carr
Realty, L.P.).

Recent Developments

         From January 1, 1997 to March 1, 1998, the Company invested
approximately $1.3 billion ($1.099 billion in cash, the assumption of $182.8
million of debt and the issuance of $26.0 million in partnership interests
("Units")) in 95 operating properties containing approximately 7.6 million
square feet and in land held for future development which is expected to support
the development of approximately 6.7 million square feet. On certain parcels of
land acquired between January 1, 1997 and March 1, 1998, the Company developed
and placed into service five properties containing an aggregate of approximately
346,000 square feet and placed under construction 31 properties which will
contain an aggregate of approximately 2.6 million square feet. The table below
provides certain information by market regarding the operating properties
acquired between January 1, 1997 and March 1, 1998:

Item 2.          PROPERTIES

         General. As of December 31, 1997, the Company owned interests in 248
operating office properties consisting of whole or partial ownership interests,
ranging from two to 16 stories each, located in 16 target markets across the
United States. As of December 31, 1997, the Company owned fee simple title or
leasehold interest in 240 operating office properties, controlling partial
interests in three operating office properties, and non-controlling partial
interests of 5% to 50% in five operating office properties. In addition, as of
December 31, 1997, the Company owned 40 office properties under development.
Except as disclosed in "Item 7. Management's Discussion and Analysis of
Financial Condition and Results of Operations Liquidity and Capital Resources,"
the Company has no immediate plans to renovate its operating office properties
other than for routine capital maintenance. The Company believes its properties
are adequately covered by insurance. The Company believes that, as a result of
its national operating system, market research capabilities, access to capital,
and experience as an owner, operator and developer of office properties, it will
continue to be able to identify and consummate acquisition and development
opportunities and to operate its portfolio more effectively than competitors
without such capabilities. The Company, however, competes in many of its target
markets with other real estate operators, some of which may have been active in
such markets for a longer period than the Company.

(1)      Includes office and retail space but excludes storage space.
(2)      Includes space for leases that have been executed and have commenced as
         of December 31, 1997.
(3)      Total annualized base rent equals total original base rent, including
         historical contractual increases and excluding (i) percentage rents,
         (ii) additional rent payable by tenants such as common area
         maintenance, real estate taxes and other expense reimbursements, (iii)
         future contractual or contingent rent escalations, and (iv) parking
         rents.
(4)      Calculated as total annualized base rent divided by net rentable area
         leased.
(5)      Includes tenants leasing 10% or more of rentable square footage (with
         the percentage of rentable square footage in parentheses).
(6)      The Company owns the improvements on the property and has a leasehold
         interest in all or a portion of the underlying land.
(7)      The Company holds a general and limited partner interest in a
         partnership that owns the property.
(8)      The Company holds a 50% joint venture interest in the joint venture
         that owns this property and a 50% joint venture interest in another
         joint venture, which holds the remaining 50% interest in the joint
         venture that owns the property. As a result of preferential rights to
         annual distributions from another venture, the Company will receive
         distributions of less than 75% (but in no event less than 50%) of the
         total amount distributed with respect to this property in each year
         until the preferential distribution requirements are satisfied, but
         will receive 100% of any subsequent distributions during the year until
         its aggregate distributions equal 75% of the cumulative distributions
         with respect to the property since inception of the partnership.
         Thereafter, the Company will receive 75% of the distributions made
         during the year with respect to the property. Upon sale of the
         property, the Company will receive 75% of the distributions until the
         Company receives its preference amount, 50% until the remaining
         venturer receives its preference amount, and 75% of the distributions
         thereafter.
(9)      The Company holds a 50% interest in the limited liability company that
         owns the property and serves as the entity's managing member.
(10)     The Company holds an effective 24% interest in the property by virtue
         of a 48% general partner interest in a partnership that owns a 50%
         general partner interest in the property.
(11)     The Company holds an effective 15% interest in the property by virtue
         of a 30.6% limited partner interest in a partnership that has a 49%

         Company holds an interest owns the improvements on the property and has
         a leasehold interest in the underlying land.
(13)     The Company holds a 50% joint venture interest, and is the managing
         partner.
(14)     The property was disposed of in January 1998.

</TABLE>



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

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

         The following table sets forth the taxability of common stock
distributions paid in 1997 and 1996:

(1)     Net income includes non-recurring deductions of approximately $2.3
        million and $1.9 million in 1996 and 1995, respectively, related to the
        write-off of the unamortized purchase price of certain third party real
        estate service contracts that were terminated in 1996 and the
        termination of an agreement to acquire the development business of The
        Evans Company in 1995, respectively.
(2)     Net loss includes a deduction for reorganization costs of $9.6 million
        and an extraordinary loss on early extinguishment of debt of $5.6
        million.
(3)     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. For purposes of calculating the
        Company's funds from operations, the Company has added amortization
        expense associated with goodwill amortization related to the purchase of
        the assets of OmniOffices Group, Inc. back to net income. The Company
        computes funds from operations in accordance with standards established
        by NAREIT, except for adding back goodwill amortization. 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. The Company's funds from
        operations in 1994 and 1993 have been restated to conform to the NAREIT
        definition of funds from operations. 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.
(4)     Net loss used to calculate funds from operations includes a deduction
        of approximately $9.6 million related to reorganization costs associated
        with the formation of the Company.

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

         The following discussion is based primarily on the Consolidated
Financial Statements of CarrAmerica Realty Corporation and its subsidiaries (the
"Company") as of December 31, 1997 and 1996, and for the years ended December
31, 1997, 1996 and 1995. The comparability of the periods is significantly
impacted by acquisitions made during 1997 and 1996. As of December 31, 1995, the
Company owned 13 properties. This number grew to 159 as of December 31, 1996 and
243 as of December 31, 1997.

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

RESULTS OF OPERATIONS - 1997 TO 1996

Real Estate Operating Revenue. Total real estate operating revenue increased
$192.7 million, or 115.6%, to $359.4 million for 1997 as compared to $166.7
million for 1996. The increase in revenue was primarily attributable to a $171.3
million and a $21.4 million increase in rental revenue and other real estate
operating revenue, respectively. The Company experienced net growth in its
rental revenue as a result of its acquisitions, and development properties
placed in service, which together contributed approximately $168.0 million of
additional rental revenue in 1997. Rental revenue from properties that were
fully operational throughout both periods increased by approximately $3.3
million primarily due to increased occupancy in these properties. Other real
estate operating revenue increased by $21.4 million, or 170.6%, for 1997 to
$33.9 million as compared to $12.5 million for 1996, primarily as a result of
executive office suites revenue earned by OmniOffices, which acquired the assets
of OmniOffices Group, Inc. in August 1997.

Real Estate Operating Expenses. Total real estate operating expenses increased
$143.8 million for 1997, or 105.0%, to $280.9 million as compared to $137.1
million for 1996. The net increase in operating expenses was attributable to a
$62.9 million increase in property operating expenses, a $19.9 million increase
in interest expense, the addition of $15.7 million in executive office suites
operating expenses associated with OmniOffices, a $6.6 million increase in
general and administrative expenses, and a $38.7 million increase in
depreciation and amortization. Property operating expenses increased $62.6
million primarily as a result of property acquisitions. The Company also
experienced an increase in property operating expenses from properties that were
fully operational in both periods of approximately $.3 million. The increase in
the Company's interest expense is primarily related to borrowings for
acquisitions. The addition of executive office suites operating expenses is a
result of the acquisition of the assets of OmniOffices Group, Inc. by
OmniOffices in August 1997. The increase in general and administrative expenses
is predominately a result of the addition of new staff to implement the
Company's business strategy. The increase in depreciation and amortization is
predominately a result of additional depreciation and amortization on the
Company's real estate acquisitions.

Other Operating Income (Expense). Other operating income (expense) increased
$8.6 million for 1997, to $8.5 million as compared to ($.1) million for 1996,
primarily due to an increase in interest income and gains on the disposition of
664,000 square feet.

Net Income. Net income of $78.1 million was earned for 1997 as compared to $24.3
million during 1996. 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 $56.3 million,
or 68.4%, to $138.6 million for 1997 as compared to $82.3 million for 1996,
primarily as a result of the acquisitions made by the Company. Net cash used by
investing activities increased $127.3 million, to $1.004 billion for 1997 as
compared to $876.9 million for 1996, primarily as a result of capital deployed
by the Company for acquisitions of office properties, land held for future
development and construction in progress. Net cash provided by financing
activities increased $48.8 million, to $861.9 million for 1997 as compared to
$813.1 million for 1996, primarily as a result of proceeds from the sale of
common and preferred stock and the issuance of unsecured notes, net of
repayments of mortgages payable and a portion of the unsecured credit facility
and the payment in dividends paid to the common and preferred stockholders.

RESULTS OF OPERATIONS - 1996 TO 1995

Real Estate Operating Revenue. Total real estate operating revenue increased
$65.8 million, or 65.3%, to $166.7 million for 1996 as compared to $100.9
million for 1995. The increase in revenue was primarily attributable to $64.6
million and $1.2 million increases in rental revenue and real estate service
revenue, respectively. The Company experienced net growth in its rental revenue
as a result of its acquisitions, which contributed approximately $68.2 million
of additional rental revenue in 1996. Rental revenue from properties that were
fully operational throughout both years decreased by approximately $3.6 million
due to increased vacancies experienced in those properties. Real estate service
revenue increased by $1.2 million, or 10.6%, for 1996 to $12.5 million as
compared to $11.3 million for 1995. The increase was primarily as a result of
development fees earned by CarrAmerica Development which was acquired in May
1996.

Real Estate Operating Expenses. Total real estate operating expenses increased
$54.4 million for 1996, or 65.8%, to $137.1 million as compared to $82.7 million
for 1995. The net increase in operating expenses was attributable to a $20.3
million increase in property operating expenses, a $9.8 million increase in
interest expense, a $4.5 million increase in general and administrative
expenses, and a $19.8 million increase in depreciation and amortization. The
increase in property operating expenses was primarily attributable to $20.2
million in operating expenses associated with property acquisitions. Exclusive
of operating expenses attributable to new property acquisitions, property
operating expenses increased by $.1 million for 1996. The increase in the
Company's interest expense is primarily related to borrowings for acquisitions.
The increase in general and administrative expenses is predominantly a result of
the addition of new staff to implement the Company's new business strategy, the
addition of approximately $1.8 million of expenses associated with CarrAmerica
Development and inflation. The increase in depreciation and amortization was
predominately a result of additional depreciation and amortization on the
Company's real estate acquisitions.

Other Operating Income (Expense). Other operating income (expense) increased $.8
million for 1996, to ($.1) million as compared to ($.9) million for 1995,
primarily as a result of an increase in interest income and the addition of
equity in earnings of CC-JM II Associates, a joint venture which owns the
Booz-Allen & Hamilton Building. The Company is a 50% venturer in this entity,
which constructed the Booz-Allen & Hamilton Building that was placed in service
in January 1996. The increases in other operating income were partially offset
by an additional loss recognized on the write-off of intangible assets.

Net Income. Net income of $24.3 million was earned for 1996 as compared to $12.1
for 1995. 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 $47.0 million,
or 133.3%, to $82.3 million for 1996 as compared to $35.3 million for 1995,
primarily as a result of the acquisitions made by the Company. Net cash used by
investing activities increased $795.3 million, to $876.9 million for 1996 as
compared to $81.6 million for 1995, primarily as a result of capital deployed by
the Company for acquisitions of office properties, land held for future
development and construction in progress. Net cash provided by financing
activities increased $776.0 million to $813.1 million provided for 1996 as
compared to $37.1 million for 1995, primarily as a result of the sale of common
and preferred stock by the Company and net borrowings for the Company's
acquisitions.

LIQUIDITY AND CAPITAL RESOURCES

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

         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 December 31, 1997 was $1.029
billion, of which $159.5 million, or 15.5%, bears a LIBOR-based floating
interest rate. The weighted average interest rate under the unsecured credit
facility for 1997 was 6.9%. Currently, the unsecured credit facility bears
interest at 90 basis points over LIBOR. The Company's mortgage payable fixed
rate indebtedness bears an effective weighted average interest rate of 8.1% at
December 31, 1997 and has a weighted average term to maturity of 5.9 years.
Based upon the Company's total market capitalization at December 31, 1997 of
$3.552 billion (the common stock price was $31.6875 per share; the total shares
of common stock, convertible preferred stock and Units outstanding was
67,012,464 and the aggregate liquidation value of the cumulative redeemable
preferred stock was $400 million), the Company's debt represented 29.0% of its
total market capitalization. The Company has a $450.0 million unsecured credit
facility with a current borrowing capacity of $312.0 million. As of March 16,
1998, the Company had $217.5 million outstanding and $94.5 million available for
draw under this unsecured credit facility.

         In first quarter of 1998, the Company developed a plan to address Year
2000 issues and began converting its computer systems to be Year 2000 compliant.
The plan provides for the conversion efforts to be completed prior to the end of
1999 for both the Company's financial and property related systems. The Year
2000 issues are the result of computer programs being written using two digits
rather than four to define the applicable year. The Company believes that
through its commitment to maintaining the highest level of systems support and
by working closely with vendors providing services to the Company's properties,
it will, through the normal course of business, convert all systems users to
Year 2000 compliant equipment prior to the end of 1999. The Company estimates
the costs associated with implementation of the plan will not be significant to
the Company's financial statements.

         The Company will require capital to invest in its existing portfolio of
operating assets for major capital projects such as large-scale renovations,
routine capital expenditures and deferred maintenance on certain properties
recently acquired and tenant related capital expenditures, such as tenant
improvements and allowances and leasing commissions. With respect to major
capital projects, the Company is planning renovations of three properties
containing 563,000 square feet during 1998 which will cost $11.9 million, or
approximately $21.00 per square foot. With respect to routine capital
expenditures and deferred maintenance on certain properties recently acquired,
the Company anticipates spending approximately $17.7 million, or approximately
$0.85 per square foot, during 1998 on its portfolio of operating assets owned as
of December 31, 1997. The Company expects this amount to decrease in subsequent
years as deferred maintenance activities are completed on recently acquired
properties and as the emphasis of the Company's growth shifts from acquiring
existing office properties to developing new properties. The Company's capital
requirements for tenant related capital expenditures are dependent upon a number
of factors, including the square footage covered by expiring leases, tenant
retention ratios and whether the expiring leases are in central business
district properties or suburban properties. As of March 1, 1998, the Company had
367,011 square feet and 2,872,184 square feet of expiring leases in central
business district properties and suburban properties, respectively.
Tenant-related capital expenditures (tenant improvements, cash allowances and
leasing commissions) were $6.17 per square foot and $6.33 per square foot for
leases executed in 1997 for the Company's central business district properties
and suburban properties, respectively. The Company intends to use cash flow from
operations and its unsecured revolving credit facility to meet its working
capital needs for its existing portfolio of operating assets.

         The Company will also require a substantial amount of capital for
development projects currently underway and planned for the future. As of March
1, 1998, the Company had 41 development projects underway which are expected to
require a total investment by the Company of $518.0 million. The Company intends
to use cash flow from operations, its unsecured, revolving credit facility and
the Company's access to public and private equity and debt markets to meet its
capital needs for development projects.

         Net cash provided by operating activities was $138.6 million for the
year ended December 31, 1997, compared to $82.3 million for the year ended
December 31, 1996. The increase in net cash provided by operating activities was
primarily a result of acquisitions made by the Company. The Company's investing
activities used approximately $1.004 billion and $876.9 million for the years
ended December 31, 1997 and 1996, 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 $1.014 billion for the year ended
December 31, 1997, as compared to $855.4 million in acquisitions during the same
period in 1996. Additionally, the Company invested approximately $36.3 million
and $11.5 million in its existing real estate assets for the years ended
December 31, 1997 and 1996, respectively. Net of distributions to the Company's
stockholders and minority interests, the Company's financing activities provided
net cash of $976.2 million and $863.4 million for the years ended December 31,
1997 and 1996, respectively. For the year ended December 31, 1997, the Company
raised $1.1 billion through the sale of common and


                                       29

<PAGE>


preferred stock and unsecured notes which was used to repay amounts outstanding
under its unsecured credit facility and its secured credit facility (which has
been canceled) and to fund acquisitions. The Company also drew amounts from its
unsecured credit facility during 1997 to finance its acquisitions and other
investing activities. For the year ended December 31, 1997, the Company's net
repayments of its unsecured credit facility were approximately $55.5 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 expects to fund capital expenditures, including tenant concession
packages, building renovations and construction costs, from (i) available funds
from operations, (ii) existing capital reserves, and (iii) if necessary, credit
facilities established with third party lenders. If these sources of funds are
insufficient, the Company's ability to make expected distributions may be
adversely impacted. As of December 31, 1997, the Company had cash of $41.9
million, of which $18.0 million was restricted.

         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. For the fourth quarter 1997, the Company increased its
quarterly dividend, to be paid in the first quarter of 1998, from $0.4375 to
$0.4625. This increase was necessary in order for the Company to be in
compliance during 1998 with the REIT requirement to distribute 95% of taxable
income.

         Management believes that the Company will have access to the capital
resources necessary to expand and develop its business. The Company may seek to
obtain funds through additional equity offerings or debt offerings in a manner
consistent with its intention to operate with a conservative borrowing policy.
The Company anticipates that adequate cash will be available to fund its
operating and administrative expenses, continuing debt service obligations, the
payment of dividends in accordance with REIT requirements in both the short term
and long term, and future acquisitions of office properties.

         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. For
purposes of calculating the Company's funds from operations, the Company has
added amortization expense associated with goodwill amortization related to the
purchase of the assets of OmniOffices Group, Inc. back to net income. The
Company computes funds from operations in accordance with standards established
by NAREIT, except for adding back goodwill amortization. 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.

ACQUISITION AND DEVELOPMENT ACTIVITY

         The following is a discussion of the Company's acquisition and
development activity during 1997. A more detailed discussion can be found in
"Item 1. Business--Recent Developments".

         During 1997, the Company acquired the following properties: in its
Pacific region, the Company acquired 51 properties containing a total of
approximately 3.3 million square feet, for an aggregate purchase price of

1997 for properties under construction were $180.1 million. An additional $62.4
million is expected to be expended for completion of projects already under
construction as of December 31, 1997.

Supplemental disclosure of noncash investing and financing activities:

(a)      During 1997, the Company funded a portion of the aggregate purchase
         price of its property acquisitions by assuming $182.8 million of debt
         and liabilities and by issuing $26.0 million of units.

(b)      During 1996, the Company funded a portion of the aggregate purchase
         price of its property acquisitions by assuming $184.4 million of debt
         and liabilities and by issuing $1.5 million of common stock and $18.0
         million of Units. The Company also repaid $1.0 million of liabilities

                 CARRAMERICA REALTY CORPORATION AND SUBSIDIARIES
                   Notes to Consolidated Financial Statements
- -------------------------------------------------------------------------------
(1)      Description of Business and Summary of Significant Accounting Policies

         (a)     Business

                 CarrAmerica Realty Corporation (the "Company") is a
                 self-administered and self-managed equity real estate
                 investment trust ("REIT"), organized under the laws of
                 Maryland, which owns, develops, acquires and operates office
                 properties. The Company's office properties primarily are
                 located in 16 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. Certain amounts for prior
                 years have been reclassified to conform with the presentation
                 for 1997.

          (c)    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.

         (d)     Development Property

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

         (e)     Tenant Leasing Costs

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

         (f)     Deferred Financing Costs

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


                                      F-7

         (g)     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 OmniOffices, 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.

         (h)     Fair Value of Financial Instruments

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

         (i)     Revenue Recognition

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

                 The Company earns real estate service revenue for certain
                 properties it manages, leases and develops for third parties
                 and revenue from its executive suites business. Such revenue is
                 recognized as earned.

         (j)     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. This standard is
                 effective for the Company's fiscal year 1998 and requires prior
                 years' comparative financial statements to be reclassified to
                 reflect the provisions of this standard.

                 Also in June 1997, the FASB issued SFAS No. 131 "Disclosures
                 about Segments of an Enterprise and Related Information," which
                 requires a public entity to report selected information about
                 operating segments in financial reports issued to shareholders.
                 It also establishes standards for related disclosures about
                 products and services, geographic areas and major customers.
                 This standard is also effective for the Company's 1998 fiscal
                 year. The Company is currently in the process of evaluating the
                 effect this new standard will have on its financial statement
                 presentation and disclosures and the required information, if
                 any, will be reflected in the Company's 1998 financial
                 statements.

          (k)    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. At December 31, 1997 and 1996, the Company's income
                 tax basis in its assets was approximately $2.5 billion and $1.5
                 billion, respectively.

                 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, and OmniOffices, Inc. ("OmniOffices"), the
                 Company's executive suites subsidiary, file separate tax
                 returns and are subject to federal, state and local income
                 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. The income taxes
                 and the effect of the asset and liability method of the
                 accounting for income taxes for these subsidiaries, are
                 insignificant to the financial statements of the Company.

         (l)     Hedging Transactions

                 From time to time, the Company enters into interest rate lock
                 and collar agreements that are designed to hedge against the
                 impact of interest rate fluctuations on certain of the
                 Company's existing and probable future long-term debt
                 instruments. Because these agreements qualify for hedge
                 accounting treatment, any gains or losses are recognized as
                 adjustments to interest expense over the lives of the
                 underlying debt instruments. For hedge agreements that are
                 terminated early or that are associated with anticipated future
                 debt instruments, gains or losses are deferred until those debt
                 instruments are entered into. If the Company determines it is

          (m)    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
                 loss.

         (n)     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.

         (o)     Stock/Unit Option Plans

                 Prior to January 1, 1996, the Company accounted for its option
                 plans in accordance with the provisions of Accounting
                 Principles Board ("APB") Opinion No. 25, Accounting for Stock
                 Issued to Employees, and related interpretations. As such,
                 compensation expenses would be recorded only if the current
                 market price of the underlying unit or stock on the date of
                 grant exceeded the exercise price. As of January 1, 1996, the
                 Company adopted SFAS No. 123, Accounting for Stock-Based
                 Compensation, which permits entities to recognize as expense,
                 over the vesting period, the fair value of all unit-based and
                 stock-based awards on the date of grant. Alternatively, SFAS
                 No. 123 allows entities to continue to apply the provisions of
                 APB Opinion No. 25 and provide pro forma net income and pro
                 forma earnings per share disclosures for employee option grants
                 made in 1995 and future years as if the fair-value-based method
                 defined in SFAS No. 123 had been applied. The Company has
                 elected to continue to apply the provisions of APB Opinion No.
                 25 and provide the pro forma disclosures permitted by SFAS No.
                 123.

         Mortgages payable are collateralized by certain rental properties and
         generally require monthly principal and/or interest payments. Mortgages
         payable mature at various dates from June 1998 through July 2019. The
         weighted average interest rate of mortgages payable was 8.1% at
         December 31, 1997 and 1996. A mortgage payable of $27.7 million at
         December 31, 1997 is held by Carr Redmond Corporation, a wholly-owned
         subsidiary of the Company, which owns the Redmond East office campus.

         The Company also 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 December 31, 1997, 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 100 basis points above the 30 day London Interbank
         Offered Rate (LIBOR). The Company has predominately selected interest
         rates equal to 1.00 percent above the 30 day LIBOR rate. The credit
         facility matures in September 2000. The weighted average effective
         interest rate for 1997 was 6.9%.

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

         In June 1997, the Company sold senior unsecured notes in the aggregate
         principal amount of $275 million of its long-term debt, in the form of
         $150 million of 7.20% notes due in 2004 and, $125 million of 7.375%
         notes due in 2007. The Company's senior unsecured notes contain various
         covenants with which the Company must comply, including but not limited
         to: limits on the aggregate amount of indebtedness the company may have
         outstanding on a consolidated basis; limits on the aggregate amount of
         secured indebtedness the Company may have outstanding on a consolidated
         basis; and, limits on the Company's required debt service payments. The
         senior unsecured notes are unconditionally guaranteed by CarrAmerica
         Realty, L.P.

         The annual maturities of debt as of December 31, 1997 are summarized as
follows (in thousands):

                1998                     $   43,621

                                         ==========

         Restricted and unrestricted cash and cash equivalents include $18.0
         million and $8.2 million of restricted cash at December 31, 1997 and
         1996, respectively, consisting primarily of escrow deposits required by
         lenders to be used for future building renovations, tenant improvements
         or as collateral for letters of credit.

         Based on the borrowing rates available to the Company for mortgages
         payable with similar terms and average maturities, the estimated fair
         value of the Company's mortgages at December 31, 1997 and 1996 was
         approximately $615.5 million and $644.5 million, respectively.

 (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 years ended December 31, 1997 and 1996, 199,223
         and 212,293 distribution paying Units, of Carr Realty, L.P. and
         CarrAmerica Realty, L.P., respectively, 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):

         The leases also provide for additional rent based on increases in the
         Consumer Price Index (CPI) and increases in operating expenses. These
         increases are generally payable in equal installments throughout the
         year, based on estimated increases, with any differences being adjusted
         in the succeeding year.

 (6)     Preferred Stock

         The Company is authorized to issue 15,000,000 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 December 31, 1997, 960,000 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.

         During 1997, the Company issued additional preferred stock as follows:

         Series C and D shares listed above are Depositary Shares, each
         representing a 1/10 fractional interest in a share of preferred stock.
         Dividends for the Series B, C and D shares are cumulative from the date
         of issuance and are payable quarterly in arrears on the last day of
         February, May, August and November of each year. These preferred shares
         are redeemable at the option of the Company not prior to the following
         dates:


                 Series B - August 12, 2002
                 Series C - November 6, 2002
                 Series D - December 19, 2002


(7)      Stock/Unit Option Plans

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

         The 1997 Employee Stock Option and Incentive Plan ("Stock Option Plan")
         allows for the grant of options to purchase the Company's common stock
         at an exercise price which is equal to the fair market value of the
         common stock at the date of grant. The Stock Option Plan was approved
         by the Company's stockholders at its Annual Meeting of Stockholders on
         May 8, 1997. At December 31, 1997, the Company had 3,000,000 shares of
         common stock reserved for issuance under the Stock Option Plan, of
         which 897,121 were outstanding. All of these options have a ten-year
         term from the date of grant and vest over a five-year period, 20% per
         year.

         The 1993 Employee Unit Option Plan allows for the grant of options to
         purchase Units of Carr Realty, L.P. (Unit options) that are exercisable
         at the fair market value of the Units at the date of grant, which is
         deemed to be equivalent to the fair market value of the Company's
         common stock at such date. Units (following exercise of Unit options)
         are redeemable for cash or common stock of the Company, at the option
         of the Company.


                                      F-14


<PAGE>


         At December 31, 1997, the Company had 1,266,900 Units reserved for
         issuance under the Employee Unit Option Plan, of which 827,000 were
         outstanding. All of these options have a ten-year term from the date of
         grant and vest over a five-year period, 20% per year.

         The Non-Employee Director Stock Option Plan provides for the grant of
         options to purchase the Company's common stock at an exercise price
         which is equal to the fair market value of the common stock on the date
         of grant. The Non-Employee Director Stock Option Plan was approved by
         the Company's stockholders at its Annual Meeting of Stockholders on
         April 28, 1995, following which each then-serving non-employee director
         was granted options to purchase 3,000 shares of the Company's common
         stock. Immediately following each annual election of directors, each
         continuing non-employee director will receive options to purchase 5,000
         shares of the Company's common stock. Each newly elected director will
         receive options to purchase 3,000 shares of common stock. The stock
         options have a 10-year term from the date of grant and vest over a
         three-year period, 33 1/3% per year. At December 31, 1997, the Company
         had 150,000 shares of common stock reserved for issuance under the
         Non-Employee Director Stock Option Plan, of which 66,333 were
         outstanding.

         The per share weighted-average fair value of Unit options and stock
         options granted during 1997 and 1996 was $2.84 and $2.15, respectively,
         on the date of grant using the Black Scholes option-pricing model with
         the following weighed-average assumptions: 1997 - expected dividend
         yield of 7.36%, risk free interest rate of 6.26%, stock volatility of
         19.42%, and expected option life of 5.46 years; 1996 - expected
         dividend yield of 7.89%, risk free interest rate of 6.08%, stock
         volatility of 19.45%, and expected option life of 4.02 years.

         The Company applies APB Opinion No. 25 in accounting for its Unit
         options and stock options and, accordingly, no compensation cost has
         been recognized for its Unit options and stock options in the financial
         statements. However, pro forma information regarding net income and
         earnings per share is required by SFAS No. 123 and has been determined
         as if the Company had accounted for its unit and stock options under
         the fair value method. For 1997, the Company's pro forma net income and
         basic EPS is $77,725 and $1.22, respectively. The pro forma effect for
         1996 is insignificant. Unit option and stock option activity during
         1997 and 1996 is as follows:

         certain of the parking garages in the Company's properties for fees
         ranging from 24 to 62 percent of gross receipts from garage operations.
         Parking Services International, Inc. is responsible for payment of all
         garage operating expenses. Parking revenue recognized is net of fees
         paid to Parking Services International, Inc. of $4.5 million in 1997,
         $1.9 million in 1996, and $1.8 million in 1995. Accounts receivable
         includes $.8 million and $.3 million at December 31, 1997 and 1996,
         respectively, due from Parking Services International, Inc.

         Accounts receivable includes management and leasing fees, development
         and architectural fees and payroll reimbursements receivable from
         affiliates of $3.6 million at December 31, 1997 and $4.0 million at

         of $2.5 million at December 31, 1997 and $2.7 million at December 31,
         1996, which receivable is collectible in quarterly installments of

         value of this receivable is $1.5 million at December 31, 1997 and $1.6
         million at December 31, 1996. The leasing commission is due from an
         unconsolidated investee partnership.

         The Company earned management, leasing, development and architectural
         fees in 1997 and 1996 from affiliated partnerships of $7.4 million in
         1997, $6.9 million in 1996, and $6.7 million in 1995.

         A wholly owned subsidiary of Clark Enterprises, Inc., a Unitholder, has
         provided construction management services to the Company. In connection
         with these services, the Company paid $1.5 million in 1997, $1.3
         million in 1996, and $.7 million in 1995. Additionally, a wholly owned
         subsidiary of Clark Enterprises, Inc. received a total of $19.6 million
         during the years of 1996, 1995 and 1994 under a construction contract
         for the Booz-Allen & Hamilton Building (in which the Company is a 50%
         joint venturer).

         The Company leases office space from a partnership affiliated with The
         Oliver Carr Company. Rent expense amounted to $1.2 million in 1997,
         $1.1 million in 1996, and $.9 million in 1995 under the lease. Future
         minimum payments under the lease are $.4 million in 1998.

         SC-USREALTY, a placement fee of $.4 million in 1996 for services
         rendered in connection with the sale of 1,740,000 shares of Series A
         Preferred Stock issued in October 1996.

         During 1997 and 1996, payments of $.1 million and $1.1 million,
         respectively were made to Security Capital Investment Research
         Incorporated, an affiliate of SC-USREALTY, for research rendered in
         connection with the acquisition of operating and development
         properties.

(9)      Gains/Losses From Dispositions of Assets

         The Company disposed of assets that are inconsistent with its long-term
         strategic or return objectives or where market conditions for sale are
         favorable. The proceeds were redeployed into other office properties
         (utilizing tax-deferred exchanges where possible). As such, during
         1997, the Company disposed of seven properties. The Company recognized
         gains totaling $5.4 million on these dispositions.

         On January 31,1996, the Company terminated an agreement to acquire the
         development business of The Evans Company ("Evans") and, as a result,
         in 1995 the Company recognized a $1.9 million loss on its investment.
         Furthermore, in 1996, the Company wrote off approximately $2.3 million
         of the unamortized purchase price of certain third-party real estate
         service contracts that were terminated during the year. These contracts
         were acquired from Evans in 1995 and were terminated early as a result
         of the sale of the properties by third-party owners.

(10)     Commitments and Contingencies

         At December 31, 1997, the Company is contingently liable on letters
         of credit amounting to approximately $1.4 million for various
         completion escrows and on performance bonds amounting to approximately
         $6.3 million to ensure completion of required public improvements on
         its construction projects.

         The Company leases certain commercial office space for its executive
         suite business under non-cancelable operating leases with initial terms
         ranging from 10 to 15 years, expiring through 2012. Future minimum
         lease payments required under these operating leases as of December 31,
         1997 were as follows:

                1998                            $ 13,857
                1999                              14,032

                                                ========

         The Company leases land beneath two office properties located in
         metropolitan Washington, D.C. The Company also leases land adjacent to
         an office property in suburban Chicago. The terms of these leases range
         from 5 years to 99 years, with the last lease maturing in the year
         2086. The minimum base annual rental payment associated with these
         leases is $1.1 million.

         In September 1997, the Company entered into an agreement with a
         counterparty to hedge against the impact that interest rate
         fluctuations may have on debt instruments the Company issued in
         February 1998. The agreement is a forward treasury lock agreement on a
         notional amount of $75 million based on the 10-year U.S. Treasury Bill
         at 6.415%. In February 1998, the Company paid $5.9 million to the
         counterparty to unwind the agreement in connection with the sale of
         $200 million of senior unsecured notes by the Company in February 1998
         (see note 12). The amount paid by the Company will be deferred and
         amortized over the term of the debt instruments as a component of
         interest expense.

         In October 1997, the Company entered into a similar agreement to
         effectively fix its interest rate as of February 26, 1998, based on the
         10-year U.S. Treasury Bill at 5.898% on a notional amount of $50
         million. On February 18, 1998, the Company paid $1.5 million to unwind
         this agreement in connection with the sale of senior unsecured notes
         described above. The amount will be deferred and amortized over the
         term of the senior unsecured notes.

         At December 31, 1997, the amount due to the counterparty under the
         forward Treasury Lock Agreements of $4.3 million has been
         deferred/accrued in the Company's financial statements.

         The Company has a 401(k) plan for employees that will match 50% of
         employee contributions up to the first 4% of an employee's pay and will
         make a base contribution of 3% of pay for participants who remain
         employed on December 31 (the end of the plan year). Company
         contributions to the plan are subject to a five-year graduated vesting
         schedule. Company contributions to the plan amounted to $.6 million in
         1997, $.3 million in 1996, and $.3 million in 1995.

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

         Southeast Denver; Austin, Texas; and suburban Chicago. In addition, as
         of December 31, 1996, the Company had three properties under
         construction: 128,000 square feet (unaudited) in suburban Atlanta; and
         two properties that will contain approximately 295,000 square feet
         (unaudited) in southeast Denver (including a build-to-suit project with

(12)     Subsequent Events

         In March 1998, the Company, through its subsidiary OmniOffices, Inc.,
         acquired the operations of an executive suites business for
         approximately $32.5 million in cash plus warrants to purchase stock of
         OmniOffices, Inc. The business has ten centers with 800 suites located
         in three markets.

         In March 1998, the Company loaned $51.0 million to finance the
         construction of two operating office buildings located in Northern
         California. The Company has the option to purchase the buildings once
         construction is complete. The interest rate on the loan during the
         option period ranges from 9.34% to 10.32%. If the option to purchase is
         not exercised prior to March 10, 2003, the loan will bear an interest
         rate of 9.0% and will mature on February 10, 2018.

         In March 1998, the Company's unsecured credit facility was amended so
         as to reduce the interest rate from 100 basis points over LIBOR to 90
         basis points over LIBOR. The amendment also increased the Company's
         availability under the facility by increasing the percentage of the
         Company's unsecured properties available for draw.

         In February 1998, the Company sold an aggregate principal amount of
         $200 million of its long-term debt, in the form of $100 million
         aggregate principal amount of 6.625% unsecured notes due in 2005 and
         $100 million aggregate principal amount of 6.875% unsecured notes due
         in 2008. The notes contain various covenants substantially similar to
         the notes issued in June 1997. The offering raised net proceeds of $198
         million which were used to acquire the suburban office properties and
         land discussed below, to pay down indebtedness under the Company's
         unsecured credit facility, and to cover costs relating to certain
         hedging contracts entered into in September and October 1997 in
         anticipation of the offering and for general corporate purposes.

         From January 1, 1998, to March 1, 1998 the Company acquired eight
         office properties and placed into service six office buildings. In
         addition, since January 1, 1998, the Company has acquired land which is
         expected to support the future development of 2.0 million square feet.
         The Company paid $130.2 million to purchase the properties and land.
         These acquisitions and properties placed in service added to the
         Company's holdings as follows (unaudited):

         In January 1998, the Company disposed of a 267,000 square foot
         (unaudited) building for $78.1 million in value and recorded a gain of
         $43.8 million. The Company entered into a contract with the purchaser

to continue to manage and lease the property. The proceeds of this transaction
have been used to acquire eight operating office properties. The debt formerly
secured by the property remains in place, under the same terms, with the newly
acquired properties serving as substitute collateral.

                               The Board of Directors and Stockholders
                               CarrAmerica Realty Corporation:

                               We have audited the accompanying consolidated
                               balance sheets of CarrAmerica Realty Corporation
                               and subsidiaries as of December 31, 1997 and 1996
                               and the related consolidated statements of
                               operations, stockholders' equity, and cash flows
                               for each of the years in the three-year period
                               ended December 31, 1997. These consolidated
                               financial statements are the responsibility of
                               the Company's management. Our responsibility is
                               to express an opinion on these consolidated
                               financial statements based on our audits.

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

                               In our opinion, the consolidated financial
                               statements referred to above present fairly, in
                               all material respects, the financial position of
                               CarrAmerica Realty Corporation and subsidiaries
                               as of December 31, 1997 and 1996, and the results
                               of their operations and their cash flows for each
                               of the years in the three-year period ended
                               December 31, 1997, in conformity with generally
                               accepted accounting principles.

                                 CarrAmerica Realty Corporation:

                                 Under date of February 6, 1998, we reported on
                                 the consolidated balance sheets of CarrAmerica
                                 Realty Corporation and subsidiaries as of
                                 December 31, 1997 and 1996, and the related
                                 consolidated statements of operations,
                                 stockholders' equity, and cash flows for each
                                 of the years in the three-year period ended
                                 December 31, 1997, which are included in this
                                 Form 10-K. In connection with our audits of the
                                 aforementioned consolidated financial
                                 statements, we also audited the related
                                 consolidated financial statement schedule in
                                 this Form 10-K. This financial statement
                                 schedule is the responsibility of the Company's
                                 management. Our responsibility is to express an
                                 opinion on this financial statement schedule
                                 based on our audits.

                                 In our opinion, this financial statement
                                 schedule, when considered in relation to the
                                 basic consolidated financial statements taken
                                 as a whole, presents fairly, in all material
                                 respects, the information set forth therein.

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

more series, as the case may be, may be embodied in and evidenced by one or more
instruments of substantially similar tenor signed by such Holders in person or
by agents duly appointed in writing. Except as herein otherwise expressly
provided, such action shall become effective when such instrument or record or
both are delivered to the Trustee and, where it is hereby expressly required, to
the Company. Such instrument or instruments (and the action embodied therein and
evidenced thereby) are herein sometimes referred to as the "Act" of the Holders
signing such instrument or instruments. Proof of execution of any such
instrument or of a writing appointing any such agent, or of the holding by any
Person of a Note, shall be sufficient for any purpose of this Indenture and
conclusive in favor of the Trustee and the Company and any agent of the Trustee
or the Company, if made in the manner provided in this Section. The record of

public or other officer authorized by law to take acknowledgments of deeds,

execution thereof. Where such execution is by a signer acting in a capacity
other than his individual capacity, such certificate or affidavit shall also
constitute sufficient proof of his authority. The fact and date of the execution
of any such instrument, or the authority of the Person executing the same, may
also be proved in any other reasonable manner which the Trustee deems
sufficient.

     (c) The ownership of Registered Notes shall be proved by the Security
Register.

     (d) If the Company shall solicit from the Holders of Registered Notes any
request, demand, authorization, direction, notice, consent, waiver or other Act,
the Company may, at its option, in or pursuant to a Board Resolution, fix in
advance a record date for the determination of Holders entitled to give such
request, demand, authorization, direction, notice, consent, waiver or other Act,
but the Company shall have no obligation to do so. Notwithstanding TIA Section
316(c), such record date shall be the record date specified in or pursuant to
such Board Resolution, which shall be a date not earlier than the date 30 days
prior to the first solicitation of Holders generally in connection therewith and
not later than the date such solicitation is completed. If such a record date is
fixed, such request, demand, authorization, direction, notice, consent, waiver
or other Act may be given before or after such record date, but only the Holders
of record at the close of business on such record date shall be deemed to be
Holders for the purposes of determining whether Holders of the requisite
proportion of Outstanding Notes of a series have authorized or agreed or
consented to such request, demand, authorization, direction, notice, consent,
waiver or other Act, and for that purpose the Outstanding Notes of a series
shall be computed as of such record date; provided that no such authorization,
agreement or consent by the Holders on such record date shall be deemed
effective unless it shall become effective pursuant to the provisions of this
Indenture not later than eleven months after the record date.

     (e) Any request, demand, authorization, direction, notice, consent, waiver
or other Act of the Holder of any Note shall bind every future Holder of the
same Note and the Holder of every Note issued upon the registration of transfer
thereof or in exchange therefor or in lieu thereof in respect of anything done,
omitted or suffered to be done by the Trustee, any Security Registrar, any
Paying Agent, any Authenticating Agent or the Company in reliance thereon,

     SECTION 105. Notices, etc., to Trustee and Company. Any request, demand,
authorization, direction, notice, consent, waiver or Act of Holders or other
document provided or permitted by this Indenture to be made upon, given or
furnished to, or filed with,

     (1) the Trustee by any Holder or by the Company shall be sufficient for
every purpose hereunder if made, given, furnished or filed in writing to or with
the Trustee at its Corporate Trust Office, or

     (2) the Company by the Trustee or by any Holder shall be sufficient for
every purpose hereunder (unless otherwise herein expressly provided) if in
writing and mailed, first class postage prepaid, to the Company addressed to it
at the address of its principal office specified in the

first paragraph of this Indenture or at any other address previously furnished
in writing to the Trustee by the Company.

notice of any event to Holders of Registered Notes by the Company or the
Trustee, such notice shall be sufficiently given (unless otherwise herein
expressly provided) if in writing and mailed, first-class postage prepaid, to
each such Holder affected by such event, at his address as it appears in the
Security Register, not later than the latest date, and not earlier than the
earliest date, prescribed for the giving of such notice. In any case where
notice to Holders of Registered Notes is given by mail, neither the failure to
mail such notice, nor any defect in any notice so mailed, to any particular
Holder shall affect the sufficiency of such notice with respect to other Holders
of Registered Notes. Any notice mailed to a Holder in the manner herein
prescribed shall be conclusively deemed to have been received by such Holder,
whether or not such Holder actually receives such notice.

     If by reason of the suspension of or irregularities in regular mail service
or by reason of any other cause it shall be impracticable to give such notice by
mail, then such notification to Holders of Registered Notes as shall be made
with the approval of the Trustee shall constitute a sufficient notification to
such Holders for every purpose hereunder.

     Any request, demand, authorization, direction, notice, consent or waiver
required or permitted under this Indenture shall be in the English language.

     Where this Indenture provides for notice in any manner, such notice may be
waived in writing by the Person entitled to receive such notice, either before
or after the event, and such waiver shall be the equivalent of such notice.
Waivers of notice by Holders shall be filed with the Trustee, but such filing
shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

     SECTION 107. Effect of Headings and Table of Contents. The Article and
Section headings herein and the Table of Contents are for convenience only and
shall not affect the construction hereof.

     SECTION 108. Successors and Assigns. All covenants and agreements in this
Indenture by the Company and the Guarantor shall be binding on their successors
and assigns, whether so expressed or not.

     SECTION 109. Separability Clause. In case any provision in this Indenture
or in any Note shall be invalid, illegal or unenforceable, the validity,
legality and enforceability of the remaining provisions shall not in any way be
affected or impaired thereby.

     SECTION 110. Benefits of Indenture. Nothing in this Indenture, or in the
Notes express or implied, shall give to any Person, other than the parties
hereto, any Security Registrar, any Paying Agent, any Authenticating Agent and
their successors hereunder and the Holders any benefit or any legal or equitable
right, remedy or claim under this Indenture.

     SECTION 111. No Personal Liability. No recourse under or upon any
obligation, covenant or agreement contained in this Indenture or in any Note, or

promoter, as such, or against any past, present or future shareholder, officer
or director, as such, of the Company or the Guarantor or of any of their
successors either directly or through the Company or the Guarantor or any of
their successors under any rule of law, statute or constitutional provision or
by the enforcement of any assessment or by any legal or equitable proceeding or
otherwise, all such liability being expressly waived and released by the
acceptance of the Notes by the Holders thereof and as part of the consideration
for the issue of the Notes.

     SECTION 112. Governing Law. This Indenture and the Notes shall be governed
by and construed in accordance with the law of the State of New York.

     SECTION 113. Legal Holidays. In any case where any Interest Payment Date,
Redemption Date, Stated Maturity or Maturity of any Note shall not be a Business
Day at any Place of Payment, then (notwithstanding any other provision of this
Indenture or any Note other than a provision in the Notes of any series which
specifically states that such provision shall apply in lieu hereof), payment of
interest or any Additional Amounts or principal (and premium, if any) need not
be made at such Place of Payment on such date, but may be made on the next
succeeding Business Day at such Place of Payment with the same force and effect
as if made on the Interest Payment Date or Redemption Date, or at the Stated
Maturity or Maturity, provided that no interest shall accrue on the amount so
payable for the period from and after such Interest Payment Date, Redemption
Date, Stated Maturity or Maturity, as the case may be.

$100,000,000, and, except as provided herein, the Company shall not execute and
the Trustee shall not authenticate or deliver 2008 Notes in excess of such
aggregate principal amount.

     Nothing contained in this Indenture, or in the Notes, is intended to or
shall limit execution by the Company or authentication or delivery by the
Trustee of Notes under the circumstances contemplated by Sections 303, 304, 305,
306, 906 and 1107 of this Indenture.

     The 2005 Notes will bear interest at a rate of 6.625% per annum and the
2008 Notes will bear interest at a rate of 6.875% per annum in each case, from
February 23, 1998 or from the immediately preceding Interest Payment Date to
which interest has been paid or duly provided for, payable semi-annually in
arrears on March 1 and September 1 of each year, commencing September 1, 1998
(each, an "Interest Payment Date"), to the Person in whose name such Note is
registered at the close of business on February 15 or August 15 (whether or not
a Business Day), as the case may be, next preceding such Interest Payment Date
(each, a "Regular Record Date"). Interest will be computed on the basis of a
360-day year comprised of twelve 30-day months. The interest so payable on any
Note which is not punctually paid or duly provided for on any Interest Payment
Date shall forthwith cease to be payable to the Person in whose name such Note
is registered on the relevant Regular Record Date, and such defaulted interest
shall instead be payable to the Person in whose name such Note is registered on
the Special Record Date or other specified date determined in accordance with
this Indenture.

     The 2005 Notes will mature on March 1, 2005 and the 2008 Notes will mature
on March 1, 2008.

Private Exchange Note will include the Restricted Securities Legend affixed
thereon.

     SECTION 302. Denominations. The Notes of each series shall be issuable in
denominations of $1,000 and integral multiples thereof.

     SECTION 303. Execution, Authentication, Delivery and Dating. The Notes
shall be executed by the Company's Chairman of the Board, Chief Financial
Officer, President, Secretary or one of its Executive Vice Presidents and by the
general partner of the Guarantor. The signature of any of these officers or
general partner on the Notes may be manual or facsimile signatures of the
present or any future such authorized officer and may be imprinted or otherwise
reproduced on the Notes. Notes bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Company or general
partner of the Guarantor shall bind the Company or the Guarantor, as the case
may be, notwithstanding that such individuals or any of them have ceased to hold
such offices prior to the authentication and delivery of such Notes or did not
hold such offices at the date of such Notes.

     At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver the Notes, executed by the Company to the
Trustee for authentication, together with a Company Order for the authentication
and delivery of such Notes, and the Trustee in accordance with the Company Order
shall authenticate and deliver such Notes.

     In authenticating such Notes, and accepting the additional responsibilities
under this Indenture in relation to such Notes, the Trustee shall be entitled to
receive (other than in the case of the Initial Notes), and (subject to TIA
Section 315(a) through 315(d)) shall be fully protected in relying upon,



<PAGE>




               (i) an Opinion of Counsel stating that


                    (a) the form or forms of such Notes have been established in
          conformity with the provisions of this Indenture;

                    (b) the terms of such Notes have been established in
          conformity with the provisions of this Indenture; and

                    (c) such Notes when completed by appropriate insertions and
          executed and delivered by the Company to the Trustee for
          authentication in accordance with this Indenture, authenticated and
          delivered by the Trustee in accordance with this Indenture and issued
          by the Company in the manner and subject to any conditions specified
          in such Opinion of Counsel, will constitute legal, valid and binding
          obligations of the Company, enforceable in accordance with their
          terms, subject to applicable bankruptcy, insolvency, reorganization
          and other similar laws of general applicability relating to or
          affecting the enforcement of creditors' rights generally and to
          general equitable principles; and

               (ii) an Officers' Certificate stating that all conditions
     precedent provided for in this Indenture relating to the issuance of the
     Notes have been complied with and that, to the best of the knowledge of the
     signers of such certificate, no Event of Default with respect to any of the
     Notes has occurred and is continuing.

     If such form or terms have been so established, the Trustee shall not be
required to authenticate such Notes if the issue of such Notes pursuant to this
Indenture will affect the Trustee's own rights, duties, obligations or
immunities under the Notes and this Indenture or otherwise in a manner which is
not reasonably acceptable to the Trustee.

     Each Registered Note shall be dated the date of its authentication.

     No Note shall be entitled to any benefit under this Indenture or be valid
or obligatory for any purpose unless there appears on such Note a certificate of
authentication substantially in the form provided for herein duly executed by
the Trustee by manual signature of an authorized signatory, and such certificate
upon any Note shall be conclusive evidence, and the only evidence, that such
Note has been duly authenticated and delivered hereunder and is entitled to the
benefits of this Indenture. Notwithstanding the foregoing, if any Note shall
have been authenticated and delivered hereunder but never issued and sold by the
Company, and the Company shall deliver such Note to the Trustee for cancellation
as provided in Section 309 together with a written statement (which need not
comply with Section 102 and need not be accompanied by an Opinion of Counsel)
stating that such Note has never been issued and sold by the Company, for all
purposes of this Indenture such Note shall be deemed never to have been
authenticated and delivered hereunder and shall never be entitled to the
benefits of this Indenture.

     SECTION 304. Temporary Notes. Pending the preparation of Definitive Notes,
the Company may execute, and upon Company Order, the Trustee shall authenticate
and deliver, temporary Notes which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the Definitive Notes in lieu of which they


<PAGE>


are issued, in registered form, and with such appropriate insertions, omissions,
substitutions and other variations as the officers executing such Notes may
determine, as conclusively evidenced by their execution of such Notes. Such
temporary Notes may be in global form.

     Except in the case of temporary Notes in global form (which shall be
exchanged in accordance with or pursuant to a Board Resolution), if temporary
Notes of any series are issued, the Company will cause Definitive Notes of that
series to be prepared without unreasonable delay. After the preparation of
Definitive Notes of such series, the temporary Notes of such series shall be
exchangeable for Definitive Notes of such series upon surrender of the temporary
Notes of such series at the office or agency of the Company in a Place of
Payment for that series, without charge to the Holder. Upon surrender for
cancellation of any one or more temporary Notes of any series, the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a
like principal amount of Definitive Notes of the same series and authorized
denominations. Until so exchanged, the temporary Notes of any series shall in
all respects be entitled to the same benefits under this Indenture as Definitive
Notes of such series.

     SECTION 305. Registration, Registration of Transfer and Exchange. The
Company shall cause to be kept at the Corporate Trust Office of the Trustee or
in any office or agency of the Company in a Place of Payment a register for each
series of Notes (the registers maintained in such office or in any such office
or agency of the Company in a Place of Payment being herein sometimes referred
to collectively as the "Security Register") in which, subject to such reasonable
regulations as it may prescribe, the Company shall provide for the registration
of Registered Notes and of transfers of Registered Notes. The Security Register
shall be in written form or any other form capable of being converted into
written form within a reasonable time. The Trustee, at its Corporate Trust
Office, is hereby initially appointed "Security Registrar" for the purpose of
registering Registered Notes and transfers of Registered Notes on such Security
Register as herein provided. In the event that the Trustee shall cease to be
Security Registrar, it shall have the right to examine the Security Register at
all reasonable times.

     Subject to the provisions of this Section 305, upon surrender for
registration of transfer of any Registered Note of any series at any office or
agency of the Company in a Place of Payment for that series, the Company shall
execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Registered Notes of the
same series, of any authorized denominations and of a like aggregate principal
amount, bearing a number not contemporaneously outstanding, and containing
identical terms and provisions. Subject to the provisions of this Section 305,
at the option of the Holder, Registered Notes of any series may be exchanged for
other Registered Notes of the same series, of any authorized denomination or
denominations and of a like aggregate principal amount, containing identical
terms and provisions, upon surrender of the Registered Notes to be exchanged at
any such office or agency. Whenever any such Registered Notes are so surrendered
for exchange, the Company shall execute, and the Trustee shall authenticate and
deliver, the Registered Notes which the Holder making the exchange is entitled
to receive.

     (a) Transfer and Exchange of Global Notes. A Global Note may not be
transferred as a whole except by DTC to a nominee of DTC, by a nominee of DTC to
another nominee of DTC, or


<PAGE>


by DTC or any such nominee to a successor of DTC or a nominee of such successor
depositary. All Global Notes will be exchanged by the Company for Definitive
Notes if (i) the Company delivers to the Trustee notice from DTC that it is
unwilling or unable to continue to act as depositary or that it is no longer a
clearing agency registered under the Exchange Act and, in either case, a
successor depositary is not appointed by the Company within 90 days after the
date of such notice from the depositary or (ii) the Company in its sole
discretion determines that the Global Notes (in whole but not in part) should be
exchanged for Definitive Notes and delivers a written notice to such effect to
the Trustee. Upon the occurrence of either of the preceding events in (i) or
(ii) above, Definitive Notes shall be issued in such names as the DTC shall
instruct the Trustee. Global Notes also may be exchanged or replaced, in whole
or in part, as provided herein. Every Note authenticated and delivered in
exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to
this Article Three, shall be authenticated and delivered in the form of, and
shall be, a Global Note. A Global Note may not be exchanged for another Note
other than as provided herein.

     (b) Transfer and Exchange of Beneficial Interests in Global Notes. The
transfer and exchange of beneficial interests in the Global Notes shall be
effected through DTC, in accordance with the provisions of this Indenture and
the Applicable Procedures. For the purposes of Subparagraphs (b)-(d) of this
Section 305, neither the Company nor the Trustee (nor any registrar or paying
agent) will have any responsibility for the performance by DTC or their
Participants or Indirect Participants of their respective obligations under the
rules and procedures governing their operations. DTC has advised the Company
that it will take any action permitted to be taken by a holder of Notes only at
the direction of one or more Participants whose accounts are credited with DTC
interests in a Global Note. Beneficial interests in the Restricted Global Notes
shall be subject to restrictions on transfer comparable to those set forth
herein to the extent required by the Securities Act. Transfers of beneficial
interests in the 144A Global Notes also shall require compliance with either
subparagraph (i) or (ii) below, as applicable, as well as one or more of the
other following subparagraphs as applicable:

               (i) Transfer of Beneficial Interests in the Same Global Note.
     Beneficial interests in any Restricted Global Note may be transferred to
     persons who take delivery thereof in the form of a beneficial interest in
     the same Restricted Global Note in accordance with the transfer
     restrictions set forth in the Restricted Securities Legend. Beneficial
     interests in any Unrestricted Global Note may be transferred only to
     persons who take delivery thereof in the form of a beneficial interest in
     an Unrestricted Global Note. No written orders or instructions shall be
     required to be delivered to the Registrar to effect the transfers described
     in 3.05(b)(i).

               (ii) All Other Transfers and Exchanges of Beneficial Interests in
     Global Notes. In connection with all transfers and exchanges of beneficial
     interests (other than a transfer of a beneficial interest in a Global Note
     to a person who takes delivery thereof in the form of a beneficial interest
     in the same Global Note), the transferor of such beneficial interest must
     deliver to DTC either (A) (1) a written order from a participant or an
     indirect participant given to DTC in accordance with the Applicable
     Procedures directing DTC to credit or cause to be credited a beneficial
     interest in another Global Note in an amount equal to the beneficial
     interest to be transferred or exchanged and (2) instructions given in
     accordance with the Applicable Procedures containing information regarding
     the participant account to be credited with such increase or (B) (1) a
     written order from a participant or an indirect participant given


<PAGE>


     to DTC directing DTC to cause to be issued a Definitive Note in an amount
     equal to the beneficial interest to be transferred or exchanged and (2)
     instructions given by DTC to the Registrar containing information regarding
     the person in whose name such Definitive Note shall be registered to effect
     the transfer or exchange referred to in (1) above. Upon an Exchange Offer
     by the Company in accordance with Section 3.05(f) hereof, the requirements
     of this clause (ii) shall be deemed to have been satisfied upon receipt by
     the Registrar of the instructions contained in a Letter of Transmittal
     delivered by the Holder of such beneficial interests in the Restricted
     Global Notes. Upon satisfaction of all of the requirements for transfer or
     exchange of beneficial interests in Global Notes contained in this
     Indenture, the Notes and otherwise applicable under the Securities Act, the
     Trustee shall adjust the principal amount of the relevant Global Note
     pursuant to Section 3.05(h) hereof.

               (iii) Transfer of Beneficial Interests to Another Restricted
     Global Note. A beneficial interest in any Restricted Global Note may be
     transferred to a Person who takes delivery thereof in the form of a
     beneficial interest in the 144A Global Note if the transfer complies with
     the requirements of clause (ii) above and DTC receives, if the transferee
     will take delivery in the form of a beneficial interest in the 144A Global
     Note, from the transferor a certificate in the form of Exhibit A hereto,
     including the certifications in item (1) thereof.

               (iv) Transfer and Exchange of Beneficial Interests in a
     Restricted Global Note for Beneficial Interests in the Unrestricted Global
     Note. A beneficial interest in any Restricted Global Note may be exchanged
     by any Holder thereof for a beneficial interest in an Unrestricted Global
     Note or transferred to a person who takes delivery thereof in the form of a
     beneficial interest in an Unrestricted Global Note if the exchange or
     transfer complies with the requirements of clause (ii) above and:

                         (A) such exchange or transfer is effected pursuant to
          the Exchange Offer in accordance with the Registration Rights
          Agreement and the Holder of the beneficial interest to be transferred,
          in the case of an exchange, or the transferee, in the case of a
          transfer, certifies in the applicable Letter of Transmittal that it is
          not (1) a broker-dealer, (2) a person participating in the
          distribution of the Exchange Notes or (3) a Person who is an affiliate
          (as defined in Rule 144) of the Company;

                         (B) any such transfer is effected pursuant to a Shelf
          Registration in accordance with the Registration Rights Agreement;

                         (C) any such transfer is effected by a Participating
          Broker-Dealer pursuant to the Exchange Registration Statement in
          accordance with the Registration Rights Agreement; or

                         (D) DTC receives the following:

                              (1) if the Holder of such beneficial interest in a
               Restricted Global Note proposes to exchange such beneficial
               interest for a beneficial interest in an


<PAGE>


               Unrestricted Global Note, a certificate from such Holder in the
               form of Exhibit B hereto, including the certifications in item
               (1)(a) thereof;

                              (2) if the Holder of such beneficial interest in a
               Restricted Global Note proposes to transfer such beneficial
               interest to a Person who shall take delivery thereof in the form
               of a beneficial interest in an Unrestricted Global Note, a
               certificate from such Holder in the form of Exhibit A hereto,
               including the certifications in item (3) thereof; and

                              (3) in each such case set forth in this
               subparagraph (D), an Opinion of Counsel in form reasonably
               acceptable to DTC to the effect that such exchange or transfer is
               in compliance with the Securities Act and that the restrictions
               on transfer contained herein and in the Restricted Securities
               Legend are not required in order to maintain compliance with the
               Securities Act.

     If any such transfer is effected pursuant to subparagraph (B) or (D) above
at a time when an Unrestricted Global Note has not yet been issued, the Company
shall issue and, upon receipt of an Authentication Order in accordance with
Section 303 of this Indenture, the Trustee shall authenticate one or more
Unrestricted Global Notes in an aggregate principal amount equal to the
principal amount of beneficial interests transferred pursuant to subparagraph
(B) or (D) above.

     Beneficial interests in an Unrestricted Global Note cannot be exchanged
for, or transferred to persons who take delivery thereof in the form of, a
beneficial interest in a Restricted Global Note.

     (c) Transfer or Exchange of Beneficial Interests for Definitive Notes.

               (i) If any Holder of a beneficial interest in a Restricted Global
     Note proposes to exchange such beneficial interest for a Definitive Note or
     to transfer such beneficial interest to a Person who takes delivery thereof
     in the form of a Definitive Note, then, upon receipt by DTC of the
     following documentation:

                    (A) if the Holder of such beneficial interest in a
          Restricted Global Note proposes to exchange such beneficial interest
          for a Definitive Note, a certificate from such Holder in the form of
          Exhibit B hereto, including, subject to Section 3.05(c)(ii) below, the
          certifications in item (2)(a) thereof;

                    (B) if such beneficial interest is being transferred to a
          QIB in accordance with Rule 144A under the Securities Act, a
          certificate to the effect set forth in Exhibit A hereto, including the
          certifications in item (1) thereof;

                    (C) if such beneficial interest is being transferred
          pursuant to an exemption from the registration requirements of the
          Securities Act in accordance with Rule 144


<PAGE>


          under the Securities Act, a certificate to the effect set forth in
          Exhibit A hereto, including the certifications in item (2)(a) thereof;

                    (D) if such beneficial interest is being transferred to an
          Institutional Accredited Investor in reliance on an exemption from the
          registration requirements of the Securities Act other than those
          listed in subparagraphs (B) through (C) above, a certificate to the
          effect set forth in Exhibit A hereto, including the certifications,
          certificates and Opinion of Counsel required by item (3) thereof, if
          applicable;

                    (E) if such beneficial interest is being transferred to the
          Company or any of its Subsidiaries, a certificate to the effect set
          forth in Exhibit B hereto, including the certifications in item (2)(b)
          thereof; or

                    (F) if such beneficial interest is being transferred
          pursuant to an effective registration statement under the Securities
          Act, a certificate to the effect set forth in Exhibit A hereto,
          including the certifications in item (2)(c) thereof, the Company shall
          cause by issuance of a Company Order to the Trustee the aggregate
          principal amount of the applicable Global Note to be reduced
          accordingly as provided herein, and the Company shall execute and the
          Trustee upon receipt of such Company Order shall authenticate and
          deliver to the person designated in the instructions a Definitive Note
          in the appropriate principal amount. Any Definitive Note issued in
          exchange for a beneficial interest in a Restricted Global Note
          pursuant to this Section 3.05(c) shall be registered in such name or
          names and in such authorized denomination or denominations as the
          Holder of such beneficial interest shall instruct DTC and the
          participant or indirect participant. The Trustee shall deliver such
          Definitive Notes to the Persons in whose names such Notes are so
          registered. Any Definitive Note issued in exchange for a beneficial
          interest in a Restricted Global Note pursuant to this Section
          3.05(c)(i) shall bear the Restricted Securities Legend and shall be
          subject to all restrictions on transfer contained therein.

               (ii) Notwithstanding Section 3.05(c)(i), a Holder of a beneficial
     interest in a Restricted Global Note may exchange such beneficial interest
     for an Unrestricted Definitive Note or may transfer such beneficial
     interest to a person who takes delivery thereof in the form of an
     Unrestricted Definitive Note only if:

                    (A) such exchange or transfer is effected pursuant to the
          Exchange Offer in accordance with the Registration Rights Agreement
          and the Holder of such beneficial interest, in the case of an
          exchange, or the transferee, in the case of a transfer, certifies in
          the applicable Letter of Transmittal that it is not (1) a
          broker-dealer, (2) a person participating in the distribution of the
          Exchange Notes or (3) a Person who is an affiliate (as defined in Rule
          144) of the Company;

                    (B) any such transfer is effected pursuant to the Shelf
          Registration in accordance with the Registration Rights Agreement;


<PAGE>


                    (C) any such transfer is effected by a participating
          Broker-Dealer pursuant to the Exchange Offer Registration Statement in
          accordance with the Registration Rights Agreement; or

                    (D) DTC receives the following:

                              (1) if the Holder of such beneficial interest in a
               Restricted Global Note proposes to exchange such beneficial
               interest for a Definitive Note that does not bear the Restricted
               Securities Legend, a certificate from such Holder in the form of
               Exhibit B hereto, including the certifications in item (1)(b)
               thereof;

                              (2) if the Holder of such beneficial interest in a
               Restricted Global Note proposes to transfer such beneficial
               interest to a person who shall take delivery thereof in the form
               of a Definitive Note that does not bear the Restricted Securities
               Legend, a certificate from such Holder in the form of Exhibit A
               hereto, including the certifications in item (3) thereof; and

                              (3) in each such case set forth in this
               subparagraph (D), an Opinion of Counsel in form reasonably
               acceptable to the Company, to the effect that such exchange or
               transfer is in compliance with the Securities Act and that the
               restrictions on transfer contained herein and in the Restricted
               Securities Legend are not required in order to maintain
               compliance with the Securities Act.

               (iii) If any Holder of a beneficial interest in an Unrestricted
     Global Note proposes to exchange such beneficial interest for a Definitive
     Note or to transfer such beneficial interest to a person who takes delivery
     thereof in the form of a Definitive Note, then, upon satisfaction of the
     conditions set forth in Section 3.05(b)(ii) hereof, the Trustee shall cause
     the aggregate principal amount of the applicable Global Note to be reduced
     accordingly pursuant to this Indenture, and the Company shall execute and
     the Trustee shall upon receipt of a Company Order authenticate and deliver
     to the Person designated in the instructions a Definitive Note in the
     appropriate principal amount. Any Definitive Note issued in exchange for a
     beneficial interest pursuant to this Section 3.05(c)(iii) shall be
     registered in such name or names and in such authorized denomination or
     denominations as the Holder of such beneficial interest shall instruct DTC
     and the participant or indirect participant. The Trustee shall deliver such
     Definitive Notes to the persons in whose names such Notes are so
     registered. Any Definitive Note issued in exchange for a beneficial
     interest pursuant to this Section 305(c)(iii) shall not bear the Restricted
     Securities Legend. A beneficial interest in an Unrestricted Global Note
     cannot be exchanged for a Definitive Note bearing the Restricted Securities
     Legend or transferred to a Person who takes delivery thereof in the form of
     a Definitive Note bearing the Restricted Securities Legend.

          certifications in item (2)(c) thereof, the Trustee shall cancel the
          Definitive Note, increase or cause to be increased the aggregate
          principal amount of, the appropriate restricted Global Note.

               (ii) A Holder of a Restricted Definitive Note may exchange such
     Note for a beneficial interest in an Unrestricted Global Note or transfer
     such Restricted Definitive Note to a Person who takes delivery thereof in
     the form of a beneficial interest in an Unrestricted Global Note only if:

               compliance with the Securities Act, and such Definitive Notes are
               being exchanged or transferred in compliance with any applicable
               blue sky securities laws of any State of the United States.

               Upon satisfaction of the conditions of any of the subparagraphs
               in this Section 3.05(d)(ii), the Trustee shall cancel the
               Definitive Notes and increase or cause to be increased the

               Company to the effect that such exchange or transfer is in

<PAGE>


          substitution thereof) and each Private Exchange Note shall bear the
          legend in substantially the following form:

          (c)(ii)-(iii), (d)(ii)-(iii), (e)(ii)-(iii) or (f) of this Section 305

          BE TRANSFERRED EXCEPT AS A WHOLE BY DTC TO A NOMINEE OF DTC OR ANOTHER
          NOMINEE OF DTC OR BY DTC OR ITS NOMINEE TO A SUCCESSOR DEPOSITORY OR
          ITS NOMINEE."

     (h) General Provisions Regarding Transfer and Exchange

     All Notes issued upon any registration of transfer or exchange of Notes
shall be the valid obligations of the Company, evidencing the same debt, and
entitled to the same benefits under this Indenture, as the Notes surrendered
upon such registration of transfer or exchange. Upon consummation of an Exchange
Offer, (i) all Outstanding Initial 2004 Notes and any Exchange Notes or

<PAGE>


or Private Exchange Notes issued in exchange therefor shall, together, be
considered one series of Notes and (ii) all Outstanding Initial 2007 Notes and
any Exchange Notes or Private Exchange Notes issued in exchange therefor shall,
together, be considered one series of Notes.

     Every Registered Note presented or surrendered for registration of transfer
or for exchange or redemption shall (if so required by the Company or the
Security Registrar) be duly endorsed, or be accompanied by a written instrument
of transfer in form satisfactory to the Company and the Security Registrar, duly
executed by the Holder thereof or his attorney duly authorized in writing.

     No service charge shall be made for any registration of transfer or
exchange of Notes, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Notes, other than exchanges
pursuant to Section 304, 906, 1107 or 1305 not involving any transfer.

     The Company, the Trustee or the Security Registrar, as applicable, shall
not be required (i) to issue, register the transfer of or exchange any Note if
such Note may be among those selected for redemption during a period beginning
at the opening of business 15 days before selection of the Notes to be redeemed
under Section 1103 and ending at the close of business on the day of the mailing
of the relevant notice of redemption or (ii) to register the transfer of or
exchange any Registered Note so selected for redemption in whole or in part,
except, in the case of any Registered Note to be redeemed in part, the portion
thereof not to be redeemed, or (iii) to issue, register the transfer of or
exchange any Note which has been surrendered for repayment at the option of the
Holder, except the portion, if any, of such Note not to be so repaid.

     SECTION 306. Mutilated, Destroyed, Lost and Stolen Notes. If any mutilated
Note is surrendered to the Trustee or the Company, together with, in appropriate
cases, such security or indemnity as may be required by the Company or the
Trustee to hold each of them or any agent of either of them harmless, the
Company shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Note of the same series and principal amount, containing
identical terms and provisions and bearing a number not contemporaneously
outstanding.

     If there shall be delivered to the Company and to the Trustee (i) evidence
to their satisfaction of the destruction, loss or theft of any Note and (ii)
such security or indemnity as may be required by them to hold each of them and
any agent of either of them harmless, then, in the absence of notice to the
Company or the Trustee that such Note has been acquired by a bona fide
purchaser, the Company shall execute and upon the Company's request the Trustee
shall authenticate and deliver, in lieu of any such destroyed, lost or stolen
Note a new Note of the same series and principal amount, containing identical
terms and provisions and bearing a number not contemporaneously outstanding.

     Notwithstanding the provisions of the immediately preceding two paragraphs,
in case any such mutilated, destroyed, lost or stolen Note has become or is
about to become due and payable, the Company in its discretion may, instead of
issuing a new Note pay such.


<PAGE>


     Upon the issuance of any new Note under this Section, the Company may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other reasonable expenses
(including the reasonable fees and expenses of the Trustee) connected therewith.

     Every new Note of any series issued pursuant to this Section in lieu of any
destroyed, lost or stolen Note, shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or
stolen Note shall be at any time enforceable by anyone, and shall be entitled to
all the benefits of this Indenture equally and proportionately with any and all
other Notes of that series duly issued hereunder.

     The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Notes.

     SECTION 307. Payment of Interest; Interest Rights Preserved. Interest on
any Registered Note that is payable, and is punctually paid or duly provided
for, on any Interest Payment Date shall be paid to the Person in whose name that
Note (or one or more Predecessor Notes) is registered at the close of business
on the Regular Record Date for such interest at the office or agency of the
Company maintained for such purpose pursuant to Section 1002; provided, however,
that each installment of interest on any Registered Note may at the Company's
option be paid by mailing a check for such interest, payable to or upon the
written order of the Person entitled thereto pursuant to Section 308, to the
address of such Person as it appears on the Security Register.

     Every permanent Global Note will provide that interest, if any, payable on
any Interest Payment Date will be paid to DTC, for the purpose of permitting DTC
to credit the interest received by it in respect of such permanent Global Note
to the accounts of the beneficial owners thereof.

     Any interest on any Registered Note of any series that is payable, but is
not punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the
registered Holder thereof on the relevant Regular Record Date by virtue of
having been such Holder, and such Defaulted Interest may be paid by the Company
at its election in each case, as provided in clause (1) or (2) below:

     (1) The Company may elect to make payment of any Defaulted Interest to the
Persons in whose names the Registered Notes of such series (or their respective
Predecessor Notes) are registered at the close of business on a special Record
Date for the payment of such Defaulted Interest, which shall be fixed in the
following manner. The Company shall notify the Trustee in writing of the amount
of Defaulted Interest proposed to be paid on each Registered Note of such series
and the date of the proposed payment (which shall not be less than 20 days after
such notice is received by the Trustee), and at the same time the Company shall
deposit with the Trustee an amount of money equal to the aggregate amount
proposed to be paid in respect of such Defaulted Interest or shall make
arrangements satisfactory to the Trustee for such deposit on or prior to the
date of the proposed payment, such money when deposited to be held in trust for
the benefit of the Persons entitled to such Defaulted Interest as in this clause
provided. Thereupon the Trustee shall fix a Special Record Date for


<PAGE>


the payment of such Defaulted Interest which shall be not more than 15 days and
not less than 10 days prior to the date of the proposed payment and not less
than 10 days after the receipt by the Trustee of the notice of the proposed
payment. The Trustee shall promptly notify the Company of such Special Record
Date and, in the name and at the expense of the Company, shall cause notice of
the proposed payment of such Defaulted Interest and the Special Record Date
therefor to be mailed, first-class postage prepaid, to each Holder of Registered
Notes of such series at his address as it appears in the Note Register not less
than 10 days prior to such Special Record Date. The Trustee may, in its
discretion, in the name and at the expense of the Company, cause a similar
notice to be published at least once in an Authorized Newspaper in each place of
payment, but such publications shall not be a condition precedent to the
establishment of such Special Record Date. Notice of the proposed payment of
such Defaulted Interest and the Special Record Date therefor having been mailed
as aforesaid, such Defaulted Interest shall be paid to the Persons in whose
names the Registered Notes of such series (or their respective Predecessor
Notes) are registered at the close of business on such Special Record Date and
shall no longer be payable pursuant to the following clause (2).

     (2) The Company may make payment of any Defaulted Interest on the
Registered Notes of any series in any other lawful manner not inconsistent with
the requirements of any securities exchange on which such Notes may be listed,
and upon such notice as may be required by such exchange, if, after notice given
by the Company to the Trustee of the proposed payment pursuant to this clause,
such manner of payment shall be deemed practicable by the Trustee.

     Subject to the foregoing provisions of this Section and Section 305, each
Note delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Note shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Note.

     SECTION 308. Persons Deemed Owners. Prior to due presentment of a
Registered Note for registration of transfer, the Company, the Trustee and any
agent of the Company or the Trustee may treat the Person in whose name such
Registered Note is registered as the owner of such Note for the purpose of
receiving payment of principal of (and premium or Make-Whole Amount, if any) and
(subject to Sections 305 and 307) interest on, such Registered Note and for all
other purposes whatsoever, whether or not such Registered Note be overdue, and
none of the Company, the Trustee or any agent of the Company or the Trustee
shall be affected by notice to the contrary.

     None of the Company, the Trustee, any Paying Agent or the Security
Registrar will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests of a Note in global form or for maintaining, supervising or reviewing
any records relating to such beneficial ownership interests.

     Notwithstanding the foregoing, with respect to any Global Note, nothing
herein shall prevent the Company, the Trustee or any agent of the Company or the
Trustee, from giving effect to any written certification, proxy or other
authorization furnished by any depositary, as a Holder, with respect to such
Global Note or impair, as between such depositary and owners of beneficial
interests in such Global Note, the operation of customary practices governing
the exercise of the rights of such depositary (or its nominee) as Holder of such
Global Note.


<PAGE>


     SECTION 309. Cancellation. All Notes surrendered for payment, redemption,
repayment at the option of the Holder, registration of transfer or exchange
shall, if surrendered to any Person other than the Trustee, be delivered to the
Trustee, and any such Notes surrendered directly to the Trustee for any such
purpose shall be promptly canceled by it. The Company may at any time deliver to
the Trustee for cancellation any Notes previously authenticated and delivered
hereunder which the Company may have acquired in any manner whatsoever, and may
deliver to the Trustee (or to any other Person for delivery to the Trustee) for
cancellation any Notes previously authenticated hereunder which the Company has
not issued and sold, and all Notes so delivered shall be promptly canceled by
the Trustee. If the Company shall so acquire any of the Notes, however, such
acquisition shall not operate as a redemption or satisfaction of the
indebtedness represented by such Notes unless and until the same are surrendered
to the Trustee for cancellation. No Notes shall be authenticated in lieu of or
in exchange for any Notes canceled as provided in this Section, except as
expressly permitted by this Indenture. Canceled Notes held by the Trustee shall
be destroyed by the Trustee and the Trustee shall deliver a certificate of such
destruction to the Company, unless, by the Company Order, the Company directs
the return of such cancelled Notes to the Company.

     SECTION 310. Computation of Interest. Interest on the Notes of each series
shall be computed on the basis of a 360-day year consisting of twelve 30-day
months.


                                   ARTICLE IV

                           SATISFACTION AND DISCHARGE

     SECTION 401. Satisfaction and Discharge of Indenture. This Indenture shall
upon Company Request cease to be of further effect with respect to any series of
Notes specified in such Company Request (except as to any surviving rights of
registration of transfer or exchange of Notes of such series herein expressly
provided for and any right to receive Additional Amounts, as provided in Section
1012), and the Trustee, upon receipt of a Company Order, and at the expense of
the Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture as to such series when,

     (1) either

               (A) all Notes of such series theretofore authenticated and
delivered other than (i) Notes of such series that have been destroyed, lost or
stolen and replaced or paid as provided in Section 306, and (ii) Notes of such
series for whose payment money has theretofore been deposited in trust or
segregated and held in trust by the Company and thereafter repaid to the Company
or discharged from such trust, as provided in Section 1003) have been delivered
to the Trustee for cancellation; or

               (B) all Notes of such series not theretofore delivered to the
Trustee for cancellation


<PAGE>


               (i) have become due and payable, or

               (ii) will become due and payable at their Stated Maturity within
     one year, or

               (iii) are to be called for redemption at the option of the
     Company within one year under arrangements satisfactory to the Trustee for
     the giving of notice of redemption by the Trustee in the name, and at the
     expense of the Company, and the Company has irrevocably deposited or caused
     to be deposited with the Trustee as trust funds in trust for the purpose an
     amount of money, sufficient to pay and discharge the entire indebtedness on
     such Notes not theretofore delivered to the Trustee for cancellation, for
     principal and premium or Make-Whole Amount, if any and interest, to the
     date of such deposit (in the case of Notes which have become due and
     payable) or to the Stated Maturity or Redemption Date, as the case may be;

     (2) the Company has paid or caused to be paid all other sums payable
hereunder by the Company; and

     (3) the Company has delivered to the Trustee an Officers' Certificate and
an Opinion of Counsel, each stating that all conditions precedent herein
provided for relating to the satisfaction and discharge of this Indenture as to
such series have been complied with.

     Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee and any predecessor Trustee under
Section 606, the obligations of the Company to any Authenticating Agent under
Section 611 and, if money shall have been deposited with and held by the Trustee
pursuant to subclause (B) of clause (1) of this Section, the obligations of the
Trustee under Section 402 and the last paragraph of Section 1003 shall survive.

     SECTION 402. Application of Trust Funds. Subject to the provisions of the
last paragraph of Section 1003, all money deposited with the Trustee pursuant to
Section 401 shall be held in trust and applied by it, in accordance with the
provisions of the Notes, and this Indenture, to the payment, either directly or
through any Paying Agent (including the Company acting as its own Paying Agent)
as the Trustee may determine, to the Persons entitled thereto, of the principal
and premium or Make-Whole Amount, if any, and any interest and Additional
Amounts for whose payment such money has deposited with or received by the
Trustee, but such money need not be segregated from other funds except to the
extent required by law.

                                    ARTICLE V

                                    REMEDIES

     SECTION 501. Events of Default. "Event of Default," wherever used herein
with respect to either series of Notes, means any one of the following events
(whatever the reason for such Event of Default and whether or not it shall be
voluntary or involuntary or be effected by operation of law or pursuant to any
judgment, decree or order of any court or any order, rule or regulation of any
administrative or governmental body):

               (1) default in the payment of any interest upon or Additional
     Amounts payable in respect of any Note of that series when such interest or
     Additional Amount becomes due and payable, and continuance of such default
     for a period of 30 days; or

               (2) default in the payment of the principal of (or premium or
     Make-Whole Amount, if any, on) any Note of that series when it becomes due
     and payable at its Maturity, upon redemption, upon declaration or
     otherwise; or

               (3) (i) default in the performance, or breach, of any covenant or
     warranty of the Company or the Guarantor in this Indenture with respect to
     any Note of that series (other than a covenant or warranty a default in
     whose performance or whose breach is elsewhere in this Section specifically
     dealt with), or (ii) the failure of any Subsidiary to comply with the
     provisions in Section 1004, and, in each case, continuance of such default
     or breach for a period of 60 days after there has been given, by registered
     or certified mail to the Company, by the Trustee or to the Company and the
     Trustee by the Holders of at least 25% in principal amount of the
     Outstanding Notes of that series a written notice specifying such default
     or breach and requiring it to be remedied and stating that such notice is a
     "Notice of Default" hereunder; or

               (4) default under any bond, debenture, note, or other evidence of
     indebtedness for money borrowed by the Company or any of its Subsidiaries
     (including obligations under leases required to be capitalized on the
     balance sheet of the lessee under GAAP), representing Recourse Indebtedness
     or indebtedness guaranteed by such party in an aggregate principal amount
     in excess of $5,000,000, or under any mortgage, indenture or instrument
     under which there may be issued or by which there may be secured or
     evidenced any indebtedness for money borrowed by the Company or any of its
     Subsidiaries (including the leases) in an aggregate principal amount in
     excess of $5,000,000, whether the indebtedness now exists or shall
     hereafter be created, which default shall have resulted in the indebtedness
     becoming or being declared due and payable prior to the date on which it
     would otherwise have become due and payable, or the obligations being
     accelerated, without the acceleration having been rescinded or annulled;

               (5) the Company or any Significant Subsidiary pursuant to or
     within the meaning of any Bankruptcy Law:

                    (A) commences a voluntary case,


<PAGE>


                    (B) consents to the entry of an order for relief against it
          in an involuntary case,

                    (C) consents to the appointment of a Custodian of it or for
          all or substantially all of its property, or

                    (D) makes a general assignment for the benefit of its
          creditors; or

               (6) a court of competent jurisdiction enters an order or decree
     under any Bankruptcy Law that:

                    (A) is for relief against the Company or any Significant
          Subsidiary in an involuntary case,

                    (B) appoints a Custodian of the Company or any Significant
          Subsidiary or for all or substantially all of either of its property,
          or

                    (C) orders the liquidation of the Company or any Significant
          Subsidiary,

and the order or decree remains unstayed and in effect for 90 days; or

               (7) except as permitted under this Indenture, the Guaranty is
     held in any judicial proceeding to be unenforceable or invalid or shall
     cease for any reason to be in full force and effect or the Guarantor shall
     deny or disaffirm, in any pleading, its obligations under the Guaranty.

     As used in this Section 501, the term "Bankruptcy Law" means Title 11 U.S.
Code or any similar Federal or State law for the relief of debtors and the term
"Custodian" means any receiver, trustee, assignee, liquidator or other similar
official under any Bankruptcy Law.

     SECTION 502. Acceleration of Maturity; Rescission and Annulment. If an
Event of Default with respect to Notes of any series at the time Outstanding
occurs and is continuing, then in every such case the Trustee or the Holders of
not less than 25% in principal amount of the Outstanding Notes of that series
may declare the principal of, and the Make-Whole Amount, if any, on, all the
Notes of that series to be due and payable immediately, by a notice in writing
to the Company (and to the Trustee if given by the Holders), and upon any such
declaration such principal and Make-Whole Amount or specified portion thereof
shall become immediately due and payable. If an Event of Default with respect to
the Notes of any series set forth in Section 501(5) or (6) of this Indenture
occurs and is continuing, then in every such case all the Notes of that series
shall become immediately due and payable, without notice to the Company, at the
principal amount thereof plus accrued interest to the date the Notes of that
series are paid plus any Make-Whole Amount, due on the Notes of that series.

     At any time after such a declaration of acceleration with respect to Notes
of any series has been made and before a judgment or decree for payment of the
money due has been obtained by the Trustee as hereinafter in this Article
provided, the Holders of a majority in principal amount of the


<PAGE>


Outstanding Notes of that series, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if:

     (1) the Company has paid or deposited with the Trustee a sum sufficient to
pay:

                    (A) all overdue installments of interest on and any
          Additional Amounts payable in respect of all Outstanding Notes of that
          series.

                    (B) the principal of (and premium or Make-Whole Amount, if
          any, on) any Outstanding Notes of that series which have become due
          otherwise than by such declaration of acceleration and interest
          thereon at the rate or rates borne by or provided for in such Notes,

                    (C) to the extent that payment of such interest is lawful,
          interest upon overdue installments of interest and any Additional
          Amounts at the rate or rates borne by or provided for in such Notes,
          and

                    (D) all sums paid or advanced by the Trustee hereunder and
          the reasonable compensation, expenses, disbursements and advances of
          the Trustee, its agents and counsel; and

     (2) all Events of Default with respect to Notes of that series, other than
the nonpayment of the principal of (or premium or Make-Whole Amount, if any) or
interest on Notes of that series which have become due solely by such
declaration of acceleration, have been cured or waived as provided in Section
513.

     No such rescission shall affect any subsequent default or impair any right
consequent thereon.

     SECTION 503. Collection of Indebtedness and Suits for Enforcement by
Trustee. The Company covenants that if:

     (1) default is made in the payment of any installment of interest or
Additional Amounts, if any, on any Note of any series when such interest or
Additional Amount becomes due and payable and such default continues for a
period of 30 days, or

     (2) default is made in the payment of the principal of (or premium or
Make-Whole Amount, if any, on) any Note of any series at its Maturity, upon
redemption, upon declaration or otherwise.

     Then the Company will, upon demand of the Trustee, pay to the Trustee, for
the benefit of the Holders of such Notes of such series, the whole amount then
due and payable on such Notes for principal (and premium or Make-Whole Amount,
if any) and interest and Additional Amount with interest upon any overdue
principal (and premium or Make-Whole Amount, if any) and, to the extent that
payment of such interest shall be legally enforceable, upon any overdue
installments of interest or Additional Amounts, if any, at the rate or rates
borne by or provided for in such Notes, and, in addition thereto, such further
amount as shall be sufficient to cover the costs and expenses of


<PAGE>


collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.

     If the Company fails to pay such amounts forthwith upon such demand, the
Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, and may
prosecute such proceeding to judgment or final decree, and may enforce the same
against the Company, or any other obligor upon such Notes of such series and
collect the moneys adjudged or decreed to be payable in the manner provided by
law out of the property of the Company or any other obligor upon such Notes of
such series, wherever situated.

     If an Event of Default with respect to Notes of any series occurs and is
continuing, the Trustee may in its discretion proceed to protect and enforce its
rights and the rights of the Holders of Notes of such series by such appropriate
judicial proceedings as the Trustee shall deem most effectual to protect and
enforce any such rights, whether for the specific enforcement of any covenant or
agreement in this Indenture or in aid of the exercise of any power granted
herein, or to enforce any other proper remedy.

     SECTION 504. Trustee May File Proofs of Claim. In case of the pendency of
any receivership, insolvency, liquidation, bankruptcy, reorganization,
arrangement, adjustment, composition or other judicial proceeding relative to
the Company or any other obligor upon the Notes or the property of the Company
or of such other obligor or their creditors, the Trustee (irrespective of
whether the principal of the Notes of any series shall then be due and payable
as therein expressed or by declaration or otherwise and irrespective of whether
the Trustee shall have made any demand on the Company for the payment of overdue
principal, premium or Make-Whole Amount, if any, or interest) shall be entitled
and empowered, by intervention in such proceeding or otherwise:

               (i) to file and prove a claim for the whole amount, or such
     lesser amount as may be provided for in the Notes of such series, of
     principal (and premium or Make-Whole Amount, if any) and interest and
     Additional Amounts, if any, owing and unpaid in respect of the Notes and to
     file such other papers or documents as may be necessary or advisable in
     order to have the claims of the Trustee (including any claim for the
     reasonable compensation, expenses, disbursements and advances of the
     Trustee, its agents and counsel) and of the Holders allowed in such
     judicial proceeding, and

               (ii) to collect and receive any moneys or other property payable
     or deliverable on any such claims and to distribute the same;

     And any custodian, receiver, assignee, trustee, liquidator, sequestrator
(or other similar official) in any such judicial proceeding is hereby authorized
by each Holder of Notes of such series to make such payments to the Trustee, and
in the event that the Trustee shall consent to the making of such payments
directly to the Holders, to pay to the Trustee any amount due to it for the
reasonable compensation, expenses, disbursements and advances of the Trustee and
any predecessor Trustee, their agents and counsel, and any other amounts due the
Trustee or any predecessor Trustee under Section 606.


<PAGE>


     Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder of a Note any
plan of reorganization, arrangement, adjustment or composition affecting the
Notes or the rights of any Holder thereof, or to authorize the Trustee to vote
in respect of the claim of any Holder of a Note in any such proceeding.

     SECTION 505. Trustee May Enforce Claims Without Possession of Notes. All
rights of action and claims under this Indenture or any of the Notes may be
prosecuted and enforced by the Trustee without the possession of any of the
Notes or the production thereof in any proceeding relating thereto, and any such
proceeding instituted by the Trustee shall be brought in its own name as trustee
of an express trust, and any recovery of judgment shall, after provision for the
payment of the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel, be for the ratable benefit of the Holders
of the Notes in respect of which such judgment has been recovered.

     SECTION 506. Application of Money Collected. Any money collected by the
Trustee pursuant to this Article shall be applied in the following order, at the
date or dates fixed by the Trustee and, in case of the distribution of such
money on account of principal (or premium or Make-Whole Amount, if any) or
interest and any Additional Amounts, upon presentation of the Notes, or both, as
the case may be, and the notation thereon of the payment if only partially paid
and upon surrender thereof if fully paid:

     FIRST: To the payment of all amounts due the Trustee and any predecessor
Trustee under Section 606;

     SECOND: To the payment of the amounts then due and unpaid upon the Notes
for principal (and premium or Make-Whole Amount, if any) and interest and any
Additional Amounts payable, in respect of which or for the benefit of which such
money has been collected, ratably, without preference or priority of any kind,
according to the aggregate amounts due and payable on such Notes for principal
(and premium or Make-Whole Amount, if any) and interest and Additional Amounts,
respectively; and

     THIRD: To the payment of the remainder, if any, to the Company.

     SECTION 507. Limitation on Suits. No Holder of any Note of any series shall
have any right to institute any proceeding, judicial or otherwise, with respect
to this Indenture, or for the appointment of a receiver or trustee, or for any
other remedy hereunder, unless:

     (1) such Holder has previously given written notice to the Trustee of a
continuing Event of Default with respect to the Notes of that series;

     (2) the Holders of not less than 25% in principal amount of the Outstanding
Notes of that series shall have made written request to the Trustee to institute
proceedings in respect of such Event of Default in its own name as Trustee
hereunder;


<PAGE>


     (3) such Holder or Holders have offered to the Trustee indemnity reasonably
satisfactory to the Trustee against the costs, expenses and liabilities to be
incurred in compliance with such request;

     (4) the Trustee for 60 days after its receipt of such notice, request and
offer of indemnity has failed to institute any such proceeding; and

     (5) no direction inconsistent with such written request has been given to
the Trustee during such 60-day period by the Holders of a majority in principal
amount of the Outstanding Notes of that series; it being understood and intended
that no one or more of such Holders shall have any right in any manner whatever
by virtue of, or by availing of, any provision of this Indenture to affect,
disturb or prejudice the rights of any other of such Holders, or to obtain or to
seek to obtain priority or preference over any other of such Holders or to
enforce any right under this Indenture, except in the manner herein provided and
for the equal and ratable benefit of all such Holders.

     SECTION 508. Unconditional Right of Holders to Receive Principal, Premium
or Make-Whole Amount, if any, Interest and Additional Amount. Notwithstanding
any other provision in this Indenture, the Holder of any Note shall have the
right which is absolute and unconditional to receive payment of the principal of
(and premium or Make-Whole Amount, if any) and (subject to Sections 305 and 307)
interest on, and any Additional Amounts in respect of such Note on the
respective due dates expressed in such Note (or, in the case of redemption, on
the Redemption Date) and to institute suit for the enforcement of any such
payment, and such rights shall not be impaired without the consent of such
Holder.

     SECTION 509. Restoration of Rights and Remedies. If the Trustee or any
Holder of a Note has instituted any proceeding to enforce any right or remedy
under this Indenture and such proceeding has been discontinued or abandoned for
any reason, or has been determined adversely to the Trustee or to such Holder,
then and in every such case, the Company, the Trustee and the Holders of Notes
shall, subject to any determination in such proceeding, be restored severally
and respectively to their former positions hereunder and thereafter all rights
and remedies of the Trustee and the Holders shall continue as though no such
proceeding had been instituted.

     SECTION 510. Rights and Remedies Cumulative. Except as otherwise provided
with respect to the replacement or payment of mutilated, destroyed, lost or
stolen Notes in the last paragraph of Section 306, no right or remedy herein
conferred upon or reserved to the Trustee or to the Holders of Notes is intended
to be exclusive of any other right or remedy, and every right and remedy shall,
to the extent permitted by law, be cumulative and in addition to every other
right and remedy given hereunder or now or hereafter existing at law or in
equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

     SECTION 511. Delay or Omission Not Waiver. No delay or omission of the
Trustee or of any Holder of any Note to exercise any right or remedy accruing
upon any Event of Default shall impair any such right or remedy or constitute a
waiver of any such Event of Default or an acquiescence therein. Every right and
remedy given by this Article or by law to the Trustee or to the Holders may


<PAGE>


be exercised from time to time, and as often as may be deemed expedient, by the
Trustee or by the Holders of Notes, as the case may be.

     SECTION 512. Control by Holders of Notes. The Holders of not less than a
majority in principal amount of the Outstanding Notes of any series shall have
the right to direct the time, method and place of conducting any proceeding for
any remedy available to the Trustee or exercising any trust or power conferred
on the Trustee with respect to the Notes of such series, provided that

     (1) such direction shall not be in conflict with any rule of law or with
this Indenture,

     (2) the Trustee may take any other action deemed proper by the Trustee
which is not inconsistent with such direction, and

     (3) the Trustee need not take any action which might involve it in personal
liability or be unduly prejudicial to the Holders of Notes of such series not
joining therein.

     SECTION 513. Waiver of Past Defaults. The Holders of not less than a
majority in principal amount of the Outstanding Notes of any series may on
behalf of the Holders of all the Notes of such series waive any past default
hereunder with respect to such series and its consequences, except a default

     (1) in the payment of the principal of (or premium or Make-Whole Amount, if
any) or interest on or Additional Amounts payable in respect of any Note of such
series, or

     (2) in respect of a covenant or provision hereof which under Article 10
cannot be modified or amended without the consent of the Holder of each
Outstanding Note of such series affected.

     Upon any such waiver, such default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured, for every purpose
of this Indenture the Company, Guarantor, Trustee and Holders shall be restored
to their former positions and rights hereunder; but no such waiver shall extend
to any subsequent or other default or Event of Default or impair any right
consequent thereon.

     SECTION 514. Waiver of Usury, Stay or Extension Laws. The Company covenants
(to the extent that it may lawfully do so) that it will not at any time insist
upon, or plead, or in any manner whatsoever claim or take the benefit or
advantage of, any usury, stay or extension law wherever enacted, now or at any
time hereafter in force, which may affect the covenants or the performance of
this Indenture; and the Company (to the extent that it may lawfully do so)
hereby expressly waives all benefit or advantage of any such law, and covenants
that it will not hinder, delay or impede the execution of any power herein
granted to the Trustee, but will suffer and permit the execution of every such
power as though no such law had been enacted.


<PAGE>


     SECTION 515. Undertaking for Costs. All parties to this Indenture agree,
and each Holder of any Note by his acceptance thereof shall be deemed to have
agreed, that any court may in its discretion require, in any suit for the
enforcement of any right or remedy under this Indenture, or in any suit against
the Trustee for any action taken or omitted by it as Trustee, the filing by any
party litigant in such suit of an undertaking to pay the costs of such suit, and
that such court may in its discretion assess reasonable costs, including
reasonable attorneys' fees, against any party litigant in such suit having due
regard to the merits and good faith of the claims or defenses made by such party
litigant; but the provisions of this Section shall not apply to any suit
instituted by the Trustee, to any suit instituted by any Holder, or group of
Holders, holding in the aggregate more than 10% in principal amount of the
Outstanding Notes, or to any suit instituted by any Holder for the enforcement
of the payment of the principal of (or premium or Make-Whole Amount, if any) or
interest on any Note on or after the respective Stated Maturities expressed in

Company agrees to pay or reimburse the Trustee for paying all reasonable costs
and expenses (including reasonable counsels' fees) of the Trustee in connection
with (a) any default and any enforcement or collection proceedings resulting
therefrom and (b) the enforcement of this Section 515.

from acting upon any resolution, certificate, statement, instrument, opinion,
report, notice, request, direction, consent, order, bond, debenture, note,
coupon or other paper or document believed by it to be genuine and to have been
signed or presented by the proper party or parties;

resolution of the Board of Directors may be sufficiently evidenced by a Board
Resolution;

     (5) whenever in the administration of this Indenture the Trustee shall deem

an Officers' Certificate;

     (6) the Trustee shall be under no obligation to exercise any of the rights
or powers vested in it by this Indenture at the request or direction of any of

make such further inquiry or investigation into such facts or matters as it may
see fit, and, if the Trustee shall determine to make such further inquiry or
investigation, it shall be entitled to examine the books, records and premises
of the Company personally or by agent or attorney;

attorneys and the Trustee shall not be responsible for any misconduct or
negligence on the part of any agent or attorney appointed with due care by it

<PAGE>


     (10) no provision of this Indenture shall be construed to relieve the

paragraph (1) of this Section;

     (d) no provision of this Indenture shall require the Trustee to expend or
risk its own funds or otherwise incur any financial liability in the performance

powers, if it shall have reasonable grounds for believing that repayment of such
funds or adequate indemnity against such risk or liability is not reasonably
assured to it.

     (11) Whether nor not therein expressly so provided, every provision of this
Indenture relating to the conduct or affecting the liability of or affording
protection to the Trustee shall be subject to the provisions of this Section.

     The permissive right of the Trustee to do the things enumerated in this
Indenture shall not be construed as a duty, and the Trustee shall not be
answerable for other than its negligence or willful misconduct.

     Except during the continuance of an Event of Default, the Trustee
undertakes to perform only such duties as are specifically set forth in this
Indenture, and no implied covenants or obligations shall be read into this
Indenture against the Trustee.

     SECTION 603. Not Responsible for Recitals or Issuance of Notes. The
recitals contained herein and in the Notes, except the Trustee's certificate of
authentication shall be taken as the statements of the Company and neither the
Trustee nor any Authenticating Agent assumes any responsibility for their
correctness. The Trustee makes no representations as to the validity, legality
or sufficiency of this Indenture or of the Notes or of any contracts referred to
herein to which the Company or the Guarantor is a party, except that the Trustee
represents that it is duly authorized to execute and deliver this Indenture,
authenticate the Notes and perform its obligations hereunder. Neither the
Trustee nor any Authenticating Agent shall be accountable for the use or
application by the Company of Notes or the proceeds thereof.


<PAGE>


     SECTION 604. May Hold Notes. The Trustee, any Paying Agent, Security
Registrar, Authenticating Agent or any other agent of the Company, in its
individual or any other capacity, may become the owner or pledgee of Notes and,
subject to TIA Sections 310(b) and 311, may otherwise deal with the Company with
the same rights it would have if it were not the Trustee, Paying Agent, Security
Registrar, Authenticating Agent or such other agent.

     SECTION 605. Money Held in Trust. Money held by the Trustee in trust
hereunder need not be segregated from other funds except to the extent required
by law. The Trustee shall be under no liability for interest on any money
received by it hereunder except as otherwise agreed with the Company.

     SECTION 606. Compensation and Reimbursement. The Company and the Guarantor
agree:

          (1) to pay to the Trustee from time to time reasonable compensation
     for all services rendered by it hereunder (which compensation shall not be
     limited by any provision of law in regard to the compensation of a trustee
     of an express trust);

          (2) except as otherwise expressly provided herein, to reimburse each
     of the Trustee and any predecessor Trustee upon its request for all
     reasonable expenses, disbursements and advances incurred or made by the
     Trustee in accordance with any provision of this Indenture (including the
     reasonable compensation and the expenses and disbursements of its agents
     and counsel), except any such expense, disbursement or advance as may be
     attributable to its negligence or bad faith; and

          (3) to indemnify each of the Trustee and any predecessor Trustee for,
     and to hold it harmless against, any loss, liability or expense incurred
     without negligence or bad faith on its own part, arising out of or in
     connection with the acceptance or administration of the trust or trusts
     hereunder, including the costs and expenses of defending itself against any
     claim or liability in connection with the exercise or performance of any of
     its powers or duties hereunder.

     When the Trustee incurs expenses or renders services in connection with an
Event of Default specified in Section 501(5) or Section 501(6), the expenses
(including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable Federal or state bankruptcy, insolvency or
other similar law.

     As security for the performance of the obligations of the Company under
this Section, the Trustee shall have a lien prior to the Holders of the Notes
upon all property and funds held or collected by the Trustee as such, except
funds held in trust for the payment of principal of (or premium or Make-Whole
Amount, if any) or interest on particular Notes.

     Notwithstanding any provision in this Indenture, the Trustee's right to
immunities and protection from liability hereunder and its rights to payment of
its fees, expenses and indemnities shall survive its resignation or removal and
the final payment or defeasance of the Notes and the termination


<PAGE>


of the Indenture and all indemnification and releases from liability granted
herein shall extend to its directors, officers, employees and agents.

     The provisions of this Section shall survive the termination of this
Indenture.

     SECTION 607. Corporate Trustee Required; Eligibility; Conflicting
Interests. There shall at all times be a Trustee hereunder which shall be
eligible to act as Trustee under TIA Section 310(a)(1) and shall have a combined
capital and surplus of at least $50,000,000. If such corporation publishes
reports of condition at least annually, pursuant to law or the requirements of
Federal, State, Territorial or District of Columbia supervising or examining
authority, then for the purposes of this Section, the combined capital and
surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. If at
any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section, it shall resign immediately in the manner and with
the effect hereinafter specified in this Article.

     SECTION 608. Resignation and Removal; Appointment of Successor. (a) No
resignation or removal of the Trustee and no appointment of a successor Trustee
pursuant to this Article shall become effective until the acceptance of
appointment by the successor Trustee in accordance with the applicable
requirements of Section 609.

     (b) The Trustee may resign at any time with respect to the Notes of one or
more series by giving written notice thereof to the Company. If an instrument of
acceptance by a successor Trustee shall not have been delivered to the Trustee
within 30 days after the giving of such notice of resignation, the resigning
Trustee may petition any court of competent jurisdiction for the appointment of
a successor Trustee.

     (c) The Trustee may be removed at any time with respect to the Notes of any
series by Act of the Holders of a majority in principal amount of the
Outstanding Notes of such series delivered to the Trustee and the Company.

     (d) If at any time:

          (1) the Trustee shall fail to comply with the provisions of TIA
     Section 310(b) after written request therefor by the Company or by any
     Holder of a Note who has been a bona fide Holder of a Note for at least six
     months, or

          (2) the Trustee shall cease to be eligible under Section 607 and shall
     fail to resign after written request therefor by the Company or by any
     Holder of a Note who has been a bona fide Holder of a Note for at least six
     months, or

          (3) the Trustee shall become incapable of acting or shall be adjudged
     bankrupt or insolvent or a receiver of the Trustee or of its property shall
     be appointed or any public officer shall take charge or control of the
     Trustee or of its property or affairs for the purpose of rehabilitation,
     conservation or liquidation,


<PAGE>


     then, in any such case, (i) the Company by or pursuant to a Board
     Resolution may remove the Trustee and appoint a successor Trustee with
     respect to all Notes, or (ii) subject to TIA Section 315(e), any Holder of
     a Note who has been a bona fide Holder of a Note for at least six months
     may, on behalf of himself and all others similarly situated, petition any
     court of competent jurisdiction for the removal of the Trustee with respect
     to all Notes and the appointment of a successor Trustee or Trustees.

     (e) If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause with respect
to the Notes of one or more series, the Company, by or pursuant to a Board
Resolution, shall promptly appoint a successor Trustee or Trustees with respect
to the Notes of that or those series (it being understood that any such
successor Trustee may be appointed with respect to the Notes of one or more or
all of such series and that at any time there shall be only one Trustee with
respect to the Notes of any particular series). If, within one year after such
resignation, removal or incapability, or the occurrence of such vacancy, a
successor Trustee with respect to the Notes of any series shall be appointed by
Act of the Holders of a majority in principal amount of the Outstanding Notes of
such series delivered to the Company and the retiring Trustee, the successor
Trustee so appointed shall, forthwith upon its acceptance or such appointment,
become the successor Trustee with respect to the Notes of such series and to
that extent supersede the successor Trustee appointed by the Company. If no
successor Trustee with respect to the Notes of any series shall have been so
appointed by the Company or the Holders of Notes and accepted appointment in the
manner hereinafter provided, any Holder of a Note who has been a bona fide
Holder of a Note of such series for at least six months may, on behalf of
himself and all others similarly situated, petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to Notes of
such series.

     (f) The Company shall give notice of each resignation and each removal of
the Trustee with respect to the Notes of any series and each appointment of a
successor Trustee with respect to the Notes of any series in the manner provided
for notices to the Holders of Notes in Section 106. Each notice shall include
the name of the successor Trustee with respect to the Notes of such series and
the address of its Corporate Trust Office.

     SECTION 609. Acceptance of Appointment by Successor. (a) In case of the
appointment hereunder of a successor Trustee with respect to all Notes, every
such successor Trustee shall execute, acknowledge and deliver to the Company and
the retiring Trustee an instrument accepting such appointment, and thereupon the
resignation or removal of the retiring Trustee shall become effective and such
successor Trustee, without any further act, deed or conveyance, shall become
vested with all the rights, powers, trusts and duties of the retiring Trustee;
but, on request of the Company or the successor Trustee, such retiring Trustee
shall, upon payment of its charges, execute and deliver an instrument
transferring to such successor Trustee all the rights, powers and trusts of the
retiring Trustee, and shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder, subject
nevertheless to its lien, if any, provided for in Section 606.

     (b) In case of the appointment hereunder of a successor Trustee with
respect to the Notes of one or more (but not all) series, the Company, the
retiring Trustee and each successor Trustee with respect to the Notes of one or
more series shall execute and deliver an indenture supplemental


<PAGE>


hereto, pursuant to Article Nine hereof, wherein each successor Trustee shall
accept such appointment and which (1) shall contain such provisions as shall be
necessary or desirable to transfer and confirm to, and to vest in, each
successor Trustee all the rights, powers, trusts and duties of the retiring
Trustee with respect to the Notes of that or those series to which the
appointment of such successor Trustee relates, (2) if the retiring Trustee is
not retiring with respect to all Notes, shall contain such provisions as shall
be deemed necessary or desirable to confirm that all of the rights, powers,
trusts and duties of the retiring Trustee with respect to the Notes of that or
those series as to which the retiring Trustee is not retiring shall continue to
be vested in the retiring Trustee, and (3) shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate
the administration of the trusts hereunder by more than one Trustee, it being
understood that nothing herein or in such supplemental indenture shall
constitute such Trustees co-trustees of the same trust and that each such
Trustee shall be trustee of a trust or trusts hereunder separate and apart from
any trust or trusts hereunder administered by any other such Trustee; and upon
the execution and delivery of such supplemental indenture the resignation or
removal of the retiring Trustee shall become effective to the extent provided
therein and each such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Notes of that or those series to
which the appointment of such successor Trustee relates; but, on request of the
Company, or any successor Trustee, such retiring Trustee shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder with respect to the Notes of that or those
series to which the appointment of such successor Trustee relates.

     (c) Upon request of any such successor Trustee, the Company shall execute
any and all instruments for more fully and certainly vesting in and confirming
to such successor Trustee all such rights, powers and trusts referred to in
paragraph (a) or (b) of this Section, as the case may be.

     (d) No successor Trustee shall accept its appointment unless at the time of
such acceptance such successor Trustee shall be qualified and eligible under
this Article.

     SECTION 610. Merger, Conversion, Consolidation or Succession to Business.
Any corporation into which the Trustee may be merged or converted or with which
it may be consolidated, or any corporation resulting from any merger, conversion
or consolidation to which the Trustee shall be a party, or any corporation
succeeding to all or substantially all of the corporate trust business of the
Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Notes shall have been authenticated, but
not delivered, by the Trustee then in office, any successor by merger,
conversion or consolidation to such authenticating Trustee may adopt such
authentication and deliver the Notes so authenticated with the same effect as if
such successor Trustee had itself authenticated such Notes. In case any Notes
shall not have been authenticated by such predecessor Trustee, any such
successor Trustee may authenticate and deliver such Notes, in either its own
name or that of its predecessor Trustee, with the full force and effect which
this Indenture provides for the certificate of authentication of the Trustee.

     SECTION 611. Appointment of Authenticating Agent. At any time when any of
the Notes remain Outstanding, the Trustee may appoint an Authenticating Agent or
Agents with respect to one or more series of Notes which shall be authorized to
act on behalf of the Trustee to authenticate


<PAGE>


Notes of such series issued upon exchange, registration of transfer or partial
redemption or repayment thereof, except upon original issuance or in replacement
of mutilated, lost, stolen or destroyed Notes, and Notes so authenticated shall
be entitled to the benefits of this Indenture and shall be valid and obligatory
for all purposes as if authenticated by the Trustee hereunder. Any such
appointment shall be evidenced by an instrument in writing signed by a
Responsible Officer of the Trustee, a copy of which instrument shall be promptly
furnished to the Company. Except on original issuance or in replacement of
mutilated, lost, stolen or destroyed Notes, wherever reference is made in this
Indenture to the authentication and delivery of Notes by the Trustee or the
Trustee's certificate of authentication, such reference shall be deemed to
include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
acceptable to the Company and shall at all times be a bank or trust company or
corporation organized and doing business and in good standing under the laws of
the United States of America or of any State or the District of Columbia,
authorized under such laws to act as Authenticating Agent, having a combined
capital and surplus of not less than $50,000,000 and subject to supervision or
examination by Federal or State authorities. If such Authenticating Agent
publishes reports of condition at least annually, pursuant to applicable law or
the requirements of the aforesaid supervising or examining authority, then for
the purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. In case at any
time an Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

     Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or further act
on the part of the Trustee or the Authenticating Agent.

     An Authenticating Agent for any series of Notes may at any time resign by
giving written notice of resignation to the Trustee for such series and to the
Company. The Trustee for any series of Notes may at any time terminate the
agency of an Authenticating Agent by giving written notice of termination to
such Authenticating Agent and the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee for such series may appoint a successor
Authenticating Agent which shall be acceptable to the Company and shall give
notice of such appointment to all Holders of Notes of the series with respect to
which such Authenticating Agent will serve in the manner set forth in Section
106. Any successor Authenticating Agent upon acceptance of its appointment
hereunder shall become vested with all the rights, powers and duties of its
predecessor hereunder, with like effect as if originally named as an
Authenticating Agent herein. No successor Authenticating Agent shall be
appointed unless eligible under the provisions of this Section.


<PAGE>


     The Company agrees to pay to each Authenticating Agent from time to time
reasonable compensation including reimbursement of its reasonable expenses for
its services under this Section.

     If an appointment with respect to one or more series is made pursuant to
this Section, the Notes of such series may have endorsed thereon, in addition to
or in lieu of the Trustee's certificate of authentication, an alternate
certificate of authentication substantially in the following form:

     This is one of the Notes of the series designated therein referred to in
the within-mentioned Indenture.

case, (1) either the Company shall be the continuing entity, or (2) the
successor entity shall be an entity organized and existing under the laws of the
United States or a State thereof and such successor entity shall expressly
assume the due and punctual payment of the principal of (and premium or
Make-Whole Amount, if any) and any interest (including all Additional Amounts,
if any, payable pursuant to Section 1012) on all of the Notes, according to
their tenor, and the due and punctual performance and observance of all of the
covenants and conditions of this Indenture to be performed by the Company, by
supplemental indenture, complying with Article Nine hereof, satisfactory to the
Trustee, executed and delivered to the Trustee by such entity and immediately
after giving effect to such transaction and treating any indebtedness which
becomes an obligation of the Company or any Subsidiary as a result thereof as
having been incurred by the Company or such Subsidiary at the time or such
transaction, no Event of Default, and no event which, after notice or the lapse
of time, or both, would become an Event of Default, shall have occurred and be
continuing.

     SECTION 802. Rights and Duties of Successor Entity. In case of any
consolidation, merger, sale, lease or conveyance permitted under Section 801 and
upon any assumption by the successor entity, such successor entity shall succeed
to and be substituted for the Company, with the same effect as if it had been
named herein as the Company, and the predecessor entity, except in the event of
a lease, shall be relieved of any further obligation under this Indenture and
the Notes. Such successor entity thereupon may cause to be signed, and may issue
either in its own name or in the name of the Company, any or all of the Notes
issuable hereunder which theretofore shall not have been signed by the Company
and delivered to the Trustee; and, upon the order of such successor entity,
instead of the Company, and subject to all the terms, conditions and limitations
in this Indenture prescribed, the Trustee shall authenticate and shall deliver
any Notes which previously shall have been signed and delivered by the officers
of the Company to the Trustee for authentication, and any Notes which such
successor entity thereafter shall cause to be signed and delivered to the
Trustee for that purpose. All of the Notes so issued shall in all respects have
the same legal rank and benefit under this Indenture as the Notes theretofore
issued in accordance with the terms of this Indenture as though all of such
Notes had been issued at the date of the execution hereof.

     In case of any such consolidation, merger, sale, lease or conveyance, such
changes in phraseology and form (but not in substance) may be made in the Notes
thereafter to be issued as may be appropriate.


     SECTION 803. Officers' Certificate and Opinion of Counsel. Any
consolidation, merger, sale, lease or conveyance permitted under Section 801 is
also subject to the condition that the Trustee receive an Officers' Certificate
of the Company and an Opinion of Counsel to the effect that any such



<PAGE>


consolidation, merger, sale, lease or conveyance, and the assumption by any
successor entity, complies with the provisions of this Article and that all
conditions precedent herein provided for relating to such transaction have been
complied with.


                                   ARTICLE IX

                             SUPPLEMENTAL INDENTURES

     SECTION 901. Supplemental Indentures without Consent of Holders. Without
the consent of any Holders of Notes, the Company and the Guarantor, when
authorized by or pursuant to a Board Resolution and the Trustee, at any time and
from time to time, may enter into one or more indentures supplemental hereto, in
form satisfactory to the Trustee, for any of the following purposes:

          (1) to evidence the succession of another Person to the Company or the
     Guarantor and the assumption by any such successor of the covenants of the
     Company or the Guarantor, respectively, herein and in the Notes contained;
     or

          (2) to add to the covenants of the Company for the benefit of the
     Holders of all or any series of Notes (and if such covenants are to be for
     the benefit of less than all series of Notes, stating that such covenants
     are expressly being included solely for the benefit of such series) or to
     surrender any right or power herein conferred upon the Company; or

          (3) to add any additional Events of Default for the benefit of the
     Holders of all or any series of Notes (and if such Events of Default are to
     be for the benefit of less than all series of Notes, stating that such
     Events of Default are expressly being included solely for the benefit of
     such series); provided, however, that in respect of any such additional
     Events of Default such supplemental indenture may provide for a particular
     period of grace after default (which period may be shorter or longer than
     that allowed in the case of other defaults) or may provide for an immediate
     enforcement upon such default or may limit the remedies available to the
     Trustee upon such default or may limit the right of the Holders of a
     majority in aggregate principal amount of that or those series of Notes to
     which such additional Events of Default apply to waive such default; or

          (4) to add to or change any of the provisions of this Indenture to
     permit or facilitate the issuance of Notes in uncertificated form, provided
     that any such action shall not adversely affect the interests of the
     Holders of Notes of any series in any material respect; or

          (5) to change or eliminate any of the provisions or this Indenture,
     provided that any such change or elimination shall become effective only
     when there is no Note Outstanding of any series created prior to the
     execution of such supplemental indenture which is entitled to the benefit
     of such provision; or

          (6) to secure the Notes; or


<PAGE>


          (7) to evidence and provide for the acceptance of appointment
     hereunder by a successor Trustee with respect to the Notes of one or more
     series and to add to or change any of the provisions of this Indenture as
     shall be necessary to provide for or facilitate the administration of the
     trusts hereunder by more than one Trustee; or

          (8) to cure any ambiguity, to correct or supplement any provision
     herein which may be defective or inconsistent with any other provision
     herein, or to make any other provisions with respect to matters or
     questions arising under this Indenture which shall not be inconsistent with
     the provisions of this Indenture, provided such provisions shall not
     adversely affect the interests of the Holders of Notes of any series in any
     material respect; or

          (9) to supplement any of the provisions of this Indenture to such
     extent as shall be necessary to permit or facilitate the defeasance and
     discharge of any series of Notes pursuant to Sections 401, 1402 and 1403;
     provided that any such action shall not adversely affect the interests of
     the Holders of Notes of such series or any other series of Notes in any
     material respect.

     SECTION 902. Supplemental Indentures with Consent of Holders. With the
consent of the Holders of not less than a majority in principal amount of all
Outstanding Notes of such series affected by such supplemental indenture, by Act
of said Holders delivered to the Company, the Guarantor and the Trustee, the
Company, and the Guarantor when authorized by or pursuant to a Board Resolution,
and the Trustee may enter into an indenture or indentures supplemental hereto
for the purpose of adding any provisions to or changing in any manner or
eliminating any of the provisions of this Indenture or of modifying in any
manner the rights of the Holders of Notes under this Indenture; provided,
however, that no such supplemental indenture shall, without the consent of the
Holder of each Outstanding Note of such series affected thereby:

          (1) change the Stated Maturity of the principal of (or premium or
     Make-Whole Amount, if any, on), or any installment of principal of or
     interest on or any Additional Amounts payable in respect thereof, any Note;
     or reduce the principal amount thereof or the rate or amount of interest
     thereon, or any premium payable upon the redemption thereof, or change any
     obligation of the Company to pay Additional Amounts pursuant to Section
     1012 (except as contemplated by Section 801(1) or 1205 and permitted by
     Section 901(1)), or adversely affect any right of repayment at the option
     of the Holder of any Note, or change any Place of Payment where, or the
     currency or currencies, currency unit or units or composite currency or
     currencies in which, any Note or any premium or the interest thereon is
     payable, or impair the right to institute suit for the enforcement of any
     such payment on or after the Stated Maturity thereof, or

          (2) reduce the percentage in principal amount of the Outstanding Notes
     of any series, the consent of whose Holders is required for any such
     supplemental indenture, or the consent of whose Holders is required for any
     waiver with respect to such series (or compliance with certain provisions
     of this Indenture or certain defaults hereunder and their consequences)
     provided for in this Indenture, or reduce the requirements of Section 1504
     for quorum or voting, or

          (3) make any change in any material provision of Article 12 that
     adversely affects the interests of any Holder of the Notes, or


<PAGE>


          (4) modify any of the provisions of this Section, Section 513 or
     Section 1013, except to increase the required percentage to effect such
     action or to provide that certain other provisions of this Indenture cannot
     be modified or waived without the consent of the Holder of each Outstanding
     Note affected thereby.

     It shall not be necessary for any Act of Holders under this Section to
approve the particular form of any proposed supplemental indenture, but it shall
be sufficient if such Act shall approve the substance thereof.

     A supplemental indenture which changes or eliminates any covenant or other
provision of this Indenture which has expressly been included solely for the
benefit of one or more particular series of Notes, or which modifies the rights
of the Holders of Notes of such series with respect to such covenant or other
provision, shall be deemed not to affect the rights under this Indenture of the
Holders of Notes of any other series.

     SECTION 903. Execution of Supplemental Indentures. In executing, or
accepting the additional trusts created by, any supplemental indenture permitted
by this Article or the modification thereby of the trusts created by this
Indenture, the Trustee shall be entitled to receive, and shall be fully
protected in relying upon, an Opinion of Counsel stating that the execution of
such supplemental indenture is authorized or permitted by this Indenture. The
Trustee may, but shall not be obligated to, enter into any such supplemental
indenture which affects the Trustee's own rights, duties or immunities under
this Indenture or otherwise.

     SECTION 904. Effect of Supplemental Indentures. Upon the execution and
delivery of any supplemental indenture under this Article, this Indenture shall
be modified in accordance therewith, and such supplemental indenture shall form
a part of this Indenture for all purposes; and every Holder of Notes theretofore
or thereafter authenticated and delivered hereunder shall be bound thereby.

     SECTION 905. Conformity with TIA. Every supplemental indenture executed
pursuant to this Article shall conform to the requirements of the TIA as then in
effect.

     SECTION 906. Reference in Notes to Supplemental Indentures. Notes of any
series authenticated and delivered after the execution of any supplemental
indenture pursuant to this Article may, and shall, if required by the Trustee,
bear a notation in form approved by the Trustee as to any matter provided for in
such supplemental indenture. If the Company shall so determine, new Notes of any
series so modified as to conform, in the opinion of the Trustee and the Company,
to any such supplemental indenture may be prepared and executed by the Company
and the Guarantor and authenticated and delivered by the Trustee in exchange for
Outstanding Notes of such series.

                                    ARTICLE X

                                    COVENANTS

     SECTION 1001. Payment of Principal, Premium (if any), Make-Whole Amount (if
any), Interest and Additional Amounts (if any). The Company covenants and agrees
for the benefit of the Holders of each series of Notes that it will duly and
punctually pay the principal of (and premium or Make-Whole Amount, if any) and
interest on and any Additional Amounts payable in respect of the Notes of that
series in accordance with the terms of such series of Notes and this Indenture.
Payment of the principal of and interest on the Notes will be made at the office
or agency of the Company maintained for that purpose in the Borough of
Manhattan, The City of New York (which shall initially be an office or agency of
the Trustee), in such coin or currency of the United States of America as at the
time of payment is legal tender for payment of public and private debts.

     SECTION 1002. Maintenance of Office or Agency. The Company shall maintain
in each Place of Payment for any series of Notes an office or agency where Notes
of that series may be presented or surrendered for payment, where Notes of that
series may be surrendered for registration of transfer or exchange and where
notices and demands to or upon the Company in respect of the Notes of that
series and this Indenture may be served.

     The Company may from time to time designate one or more other offices or
agencies where the Notes of one or more series may be presented or surrendered
for any or all of such purposes, and may from time to time rescind such
designations; provided, however, that no such designation or rescission shall in
any manner relieve the Company of its obligation to maintain an office or agency
in accordance with the requirements set forth above for Notes of any series for
such purposes. The Company will give prompt written notice to the Trustee of any
such designation or rescission and of any change in the location of any such
other office or agency. The Company hereby designates as a Place of Payment
where the Notes may be presented or surrendered for payment, where the Notes may
be surrendered for registration of transfer or exchange or where notices and
demands to and upon the Company in respect of the Notes and this Indenture, the
office or agency of the Company in the Borough of Manhattan, The City of New
York, and initially appoints the Trustee at its Corporate Trust Office as Paying
Agent in such city and as its agent to receive all such presentations,
surrenders, notices and demands.

     SECTION 1003. Money for Notes Payments to Be Held in Trust. If the Company
shall at any time act as its own Paying Agent with respect to any series of the
Notes the Company will, on or before each due date of the principal of and
premium or Make-Whole Amount, if any, or interest on or Additional Amounts in
respect of, any of the Notes, segregate and hold in trust for the benefit of the
Persons entitled thereto a sum sufficient to pay the principal (and premium or
Make-Whole Amount, if any) or interest or Additional Amounts so becoming due
until such sums shall be paid to such Persons or otherwise disposed of as herein
provided, and will promptly notify the Trustee of the Company's action or
failure so to act.


<PAGE>


     Whenever the Company shall have one or more Paying Agents for any series of
Notes it will, on or before each due date of the principal of (and premium or
Make-Whole Amount, if any), or interest on or Additional Amounts in respect of,
any Notes of that series, deposit with a Paying Agent a sum sufficient to pay
the principal (and premium or Make-Whole Amount, if any) or interest or
Additional Amounts, so becoming due, such sum to be held in trust for the
benefit of the Persons entitled to such principal, premium or interest or
Additional Amounts and (unless such Paying Agent is the Trustee) the Company
will promptly notify the Trustee of its action or failure so to act.

     The Company will cause each Paying Agent other than the Trustee to execute
and deliver to the Trustee an instrument in which such Paying Agent shall agree
with the Trustee, subject to the provisions of this Section, that such Paying
Agent will

          (1) hold all sums held by it for the payment of principal of (and
     premium or Make-Whole Amount, if any) or interest on the Notes in trust for
     the benefit of the Persons entitled thereto until such sums shall be paid
     to such Persons or otherwise disposed of as herein provided;

          (2) give the Trustee notice of any default by the Company (or any
     other obligor upon the Notes) in the making of any such payment of
     principal (or premium or Make-Whole Amount, if any) or interest; and

          (3) at any time during the continuance of any such default upon the
     written request of the Trustee, forthwith pay to the Trustee all sums so
     held in trust by such Paying Agent.

     The Company may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying Agent, such sums to be held by the Trustee upon the
same trusts as those upon which such sums were held by the Company or such
Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such
Paying Agent shall be released from all further liability with respect to such
sums.

     Except as otherwise provided in the Notes, any money deposited with the
Trustee or any Paying Agent, or then held by the Company, in trust for the
payment of the principal of (and premium or Make-Whole Amount, if any) or
interest on or Additional Amounts in respect of, any Note of any series and
remaining unclaimed for two years after such principal (or premium or Make-Whole
Amount, if any) or interest or Additional Amounts has become due and payable
shall be paid to the Company upon Company Request or (if then held by the
Company) shall be discharged from such trust; and the Holder of such Note shall
thereafter, as an unsecured general creditor, look only to the Company for
payment of such principal of (and premium or Make-Whole Amount, if any) or
interest or Additional Amounts in respect of, on any Note, without interest
thereon, and all liability of the Trustee or such Paying Agent with respect to
such trust money, and all liability of the Company as trustee thereof, shall
thereupon cease; provided, however, that the Trustee or such Paying Agent,
before being required to make any such repayment, may at the expense of the
Company cause to be published once, in an Authorized Newspaper, notice that such
money remains unclaimed and that, after a date specified therein, which shall
not be less than 30 days from the date of such publication, any unclaimed
balance of such money then remaining will be repaid to the Company.


<PAGE>


     SECTION 1004. Limitations on Incurrence of Indebtedness. Neither the
Company nor any Subsidiary will incur any Indebtedness if, immediately after
giving effect to the incurrence of that additional Indebtedness and the
application of the proceeds thereof, the aggregate principal amount of all
outstanding Indebtedness of the Company and its Subsidiaries on a consolidated
basis determined in accordance with GAAP is greater than 60% of the sum of
(without duplication) (i) the Total Assets of the Company and its Subsidiaries
as of the end of the calendar quarter covered in the Company's Annual Report on
Form 10-K or Quarterly Report on Form 10-Q, as the case may be, most recently
filed with the Commission (or, if the filing is not permitted under the Exchange
Act, with the Trustee) prior to the incurrence of the additional Indebtedness
and (ii) the purchase price of any real estate assets or mortgages receivable
acquired and the amount of any securities offering proceeds received (to the
extent that the proceeds were not used to acquire real estate assets or
mortgages receivable or used to reduce Indebtedness), by the Company or any
Subsidiary since the end of the calendar quarter, including those proceeds
obtained in connection with the incurrence of the additional Indebtedness.

     In addition to the foregoing limitation on the incurrence of Indebtedness,
neither the Company nor any Subsidiary will incur any Indebtedness secured by
any Encumbrance upon any of the property of the Company or any Subsidiary if,
immediately after giving effect to the incurrence of the additional Indebtedness
and the application of the proceeds thereof, the aggregate principal amount of
all outstanding Indebtedness of the Company and its Subsidiaries on a
consolidated basis which is secured by any Encumbrance on property of the
Company or any Subsidiary is greater than 40% of the sum of (without
duplication) (i) the Total Assets of the Company and its Subsidiaries as of the
end of the calendar quarter covered in the Company's Annual Report on Form 10-K
or Quarterly Report on Form 10-Q, as the case may be, most recently filed with
the Commission (or, if the filing is not permitted under the Exchange Act, with
the Trustee) prior to the incurrence of the additional Indebtedness and (ii) the
purchase price of any real estate assets or mortgages receivable acquired and
the amount of any securities offering proceeds received (to the extent that the
proceeds were not used to acquire real estate assets or mortgages receivable or
used to reduce Indebtedness), by the Company or any Subsidiary since the end of
the calendar quarter, including those proceeds obtained in connection with the
incurrence of the additional Indebtedness.

     The Company and its Subsidiaries may not at any time own Total Unencumbered
Assets equal to less than 150% of the aggregate outstanding principal amount of
the Unsecured Indebtedness of the Company and its Subsidiaries on a consolidated
basis.

     In addition to the foregoing limitations on the incurrence of Indebtedness,
neither the Company nor any Subsidiary will incur any Indebtedness if the ratio
of Consolidated Income Available for Debt Service to the Annual Service Charge
for the four consecutive fiscal quarters most recently ended prior to the date
on which the additional Indebtedness is to be incurred shall have been less than
1.5:1 on a pro forma basis after giving effect thereto and to the application of
the proceeds therefrom, and calculated on the assumption that (i) the
Indebtedness and any other Indebtedness incurred by the Company and its
Subsidiaries since the first day of the four-quarter period and the application
of the proceeds therefrom, including to finance other Indebtedness, had occurred
at the beginning of the period, (ii) the repayment or retirement of any other
Indebtedness by the Company and its Subsidiaries since the first day of the
four-quarter period had been repaid or retired at the beginning of that period


<PAGE>


(except that, in making the computation, the amount of Indebtedness under any
revolving credit facility shall be computed based upon the average daily
balance of the Indebtedness during that period), (iii) in the case of Acquired
Indebtedness or Indebtedness incurred in connection with any acquisition since
the first day of the four-quarter period, the related acquisition had occurred
as of the first day of the period with the appropriate adjustments with respect
to the acquisition being included in the pro forma calculation, and (iv) in the
case of any acquisition or disposition by the Company or its Subsidiaries of any
asset or group of assets since the first day of the four-quarter period, whether
by merger, stock purchase or sale, or asset purchase or sale, the acquisition or
disposition and any related repayment of Indebtedness had occurred as of the
first day of the period with the appropriate adjustments with respect to the
acquisition or disposition being included in the pro forma calculation.

     SECTION 1005. [Omitted].

     SECTION 1006. Existence. Subject to Article Eight, the Company will do or
cause to be done all things necessary to preserve and keep in full force and
effect its existence, rights and franchises; provided, however, that the Company
shall not be required to preserve any right or franchise if the Board of
Directors shall determine that the preservation thereof is no longer desirable
in the conduct of the business of the Company and that the loss thereof is not
disadvantageous in any material respect to the Holders.

     SECTION 1007. Maintenance of Properties. The Company will cause all of its
material properties used or useful in the conduct of its business or the
business of any Subsidiary to be maintained and kept in good condition, repair
and working order and supplied with all necessary equipment and will cause to be
made all necessary repairs, renewals, replacements, betterments and improvements
thereof, all as in the judgment of the Company may be necessary so that the
business carried on in connection therewith may be properly and advantageously
conducted at all times; provided, however, that nothing in this Section shall
prevent the Company or any Subsidiary from selling or otherwise disposing for
value its properties in the ordinary course of its business.

     SECTION 1008. Insurance. The Company will, and will cause each of its
Subsidiaries to, keep all of its insurable properties insured against loss or
damage at least equal to their then full insurable value with financially sound
and reputable insurers.

     SECTION 1009. Payment of Taxes and Other Claims. The Company will pay or
discharge or cause to be paid or discharged, before the same shall become
delinquent, (1) all taxes, assessments and governmental charges levied or
imposed upon it or any Subsidiary or upon the income, profits or property of the
Company or any Subsidiary, and (2) all lawful claims for labor, materials and
supplies which, if unpaid, might by law become a lien upon the property of the
Company or any Subsidiary; provided, however, that the Company shall not be
required to pay or discharge or cause to be paid or discharged any such tax,
assessment, charge or claim whose amount, applicability or validity is being
contested in good faith by appropriate proceedings.

     SECTION 1010. Provision of Financial Information. Whether or not the
Company is subject to Section 13 or 15(d) of the Exchange Act, the Company will,
to the extent permitted under the Exchange Act, file with the Commission the
annual reports, quarterly reports and other documents


<PAGE>


which the Company would have been required to file with the Commission pursuant
to such Section 13 or 15(d) (the "Financial Statements") if the Company were so
subject, such documents to be filed with the Commission on or prior to the
respective dates (the "Required Filing Dates") by which the Company would have
been required so to file such documents if the Company were so subject. The
Company and the Guarantor will, for so long as any of the Initial Notes are
outstanding, furnish to Holders of the Initial Notes and to security analysts
and prospective investors, upon their request, the information required to be
delivered pursuant to Rule 144A(d)(4) of the Securities Act.

     The Company will also in any event (x) within 15 days of each Required
Filing Date (i) transmit by mail to all Holders, as their names and addresses
appear in the Security Register, without cost to such Holders copies of the
annual reports and quarterly reports which the Company would have been required
to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act
if the Company were subject to such Sections, and (ii) file with the Trustee
copies of the annual reports, quarterly reports and other documents which the
Company would have been required to file with the Commission pursuant to Section
13 or 15(d) of the Exchange Act if the Company were subject to such Sections and
(y) if filing such documents by the Company with the Commission is not permitted
under the Exchange Act, promptly upon written request and payment of the
reasonable cost of duplication and delivery, supply copies of such documents to
any prospective Holder.

     SECTION 1011. Statement as to Compliance. The Company and the Guarantor
will deliver to the Trustee, within 120 days after the end of each fiscal year,
a brief certificate from the principal executive officer, principal financial
officer or principal accounting officer as to his or her knowledge of the
Company's compliance with all conditions and covenants under this Indenture and,
in the event of any noncompliance, specifying such noncompliance and the nature
and status thereof. For purposes of this Section 1011, such compliance shall be
determined without regard to any period of grace or requirement of notice under
this Indenture.

     SECTION 1012. Additional Amounts. If any Notes of a series provide for the
payment of Additional Amounts, the Company will pay to the Holder of any Note of
such series such Additional Amounts as may be specified in this Indenture.
Whenever in this Indenture there is mentioned, in any context except in the case
of Section 502(1), the payment of interest on, or in respect of, any Note of any
series, any such mention shall be deemed to include mention of the payment of
Additional Amounts provided by the terms of such series established pursuant to
this Indenture to the extent that, in such context, Additional Amounts are, were
or would be payable in respect thereof pursuant to such terms and express
mention of the payment of Additional Amounts (if applicable) in any provisions
hereof shall not be construed as excluding Additional Amounts in those
provisions hereof where such express mention is not made.

     If the Notes of a series provide for the payment of Additional Amounts, at
least 10 days prior to the first Interest Payment Date with respect to that
series of Notes (or if the Notes of that series will not bear interest prior to
Maturity, the first day on which a payment of principal and any premium is
made), and at least 10 days prior to each date of payment of principal and any
premium or interest if there has been any change with respect to the matters set
forth in the below-mentioned Officers' Certificate, the Company will furnish the
Trustee and the Company's principal Paying Agent or Paying Agents, if other than
the Trustee, with an Officers' Certificate instructing the Trustee and such
Paying


<PAGE>

Agent or Paying Agents whether such payment of principal of and any premium or
interest on the Notes of that series shall be made to Holders of Notes of that
series who are not United States persons without withholding for or on account
of any tax, assessment or other governmental charge described in the Notes of
the series. If any such withholding shall be required, then such Officers'
Certificate shall specify by country the amount, if any, required to be withheld
on such payments to such Holders of Notes of that series and the Company will
pay to the Trustee or such Paying Agent the Additional Amounts required by the
terms of such Notes. If the Trustee or any Paying Agent, as the case may be,
shall not so receive the above-mentioned certificate, then the Trustee or such
Paying Agent shall be entitled (i) to assume that no such withholding or
deduction is required with respect to any payment of principal or interest with
respect to any Notes of a series until it shall have received a certificate
advising otherwise and (ii) to make all payments of principal and interest with
respect to the Notes of a series without withholding or deductions until
otherwise advised. The Company covenants to indemnify the Trustee and any Paying
Agent for, and to hold them harmless against, any loss, liability or expense
reasonably incurred without negligence or bad faith on their part arising out of
or in connection with actions taken or omitted by any them or in reliance on any
Officers' Certificate furnished pursuant to this Section or in reliance on the
Company's not furnishing such an Officers' Certificate.

     SECTION 1013. Waiver of Certain Covenants. The Company may omit in any
particular instance to comply with any term, provision or condition set forth in
Sections 1004 to 1010, inclusive, if before or after the time for such
compliance the Holders of at least a majority in principal amount of all
outstanding Notes of such series, by Act of such Holders, either waive such
compliance in such instance or generally waive compliance with such covenant or
condition, but no such waiver shall extend to or affect such covenant or
condition except to the extent so expressly waived, and, until such waiver shall
become effective, the obligations of the Company and the duties of the Trustee
in respect of any such term, provision or condition shall remain in full force
and effect.


                                   ARTICLE XI

                               REDEMPTION OF NOTES

     SECTION 1101. Applicability of Article. The Notes may be redeemed at any
time at the option of the Company, in whole or in part, at a redemption price
equal to the sum of (i) the principal amount of the Notes being redeemed plus
accrued interest thereon to the Redemption Date and (ii) the Make-Whole Amount,
if any, with respect to such Notes (the "Redemption Price"). The Notes shall be
redeemable in accordance with their terms and in accordance with this Article.

     SECTION 1102. Election to Redeem; Notice to Trustee. The election of the
Company to redeem any Notes shall be evidenced by or pursuant to a Board
Resolution. In case of any redemption at the election of the Company of less
than all of the Notes of any series, the Company shall, at least 45 days prior
to the giving of the notice of redemption required by Section 1104 (unless a
shorter notice shall be satisfactory to the Trustee), notify the Trustee of such
Redemption Date and of the principal amount of Notes of such series to be
redeemed. In the case of any redemption of Notes prior to the expiration of any
restriction on such redemption provided in the terms of such Notes or


<PAGE>


elsewhere in this Indenture, the Company shall furnish the Trustee with an
Officers' Certificate evidencing compliance with such restriction.

     SECTION 1103. Selection by Trustee of Notes to Be Redeemed. If less than
all of the Notes of any series are to be redeemed, the particular Notes to be
redeemed shall be selected not more than 60 days prior to the Redemption Date by
the Trustee, from the Outstanding Notes of such series not previously called for
redemption, by such method as the Trustee shall deem fair and appropriate and
which may provide for the selection for redemption of portions (equal to the
minimum authorized denomination for Notes of that series or any integral
multiple thereof) of the principal amount of Notes of such series of a
denomination larger than the minimum authorized denomination for Notes of that
series.

     The Trustee shall promptly notify the Company and the Security Registrar
(if other than itself) in writing of the Notes selected for redemption and, in
the case of any Notes selected for partial redemption, the principal amount
thereof to be redeemed.

     For all purposes of this Indenture, unless the context otherwise requires,
all provisions relating to the redemption of Notes shall relate, in the case of
any Note redeemed or to be redeemed only in part, to the portion of the
principal amount of such Note which has been or is to be redeemed.

     SECTION 1104. Notice of Redemption. Notice of redemption shall be given in
the manner provided in Section 106, not less than 30 days nor more than 60 days
prior to the Redemption Date to each Holder of Notes to be redeemed, but failure
to give such notice in the manner herein provided to the Holder of any Note
designated for redemption as a whole or in part, or any defect in the notice to
any such Holder, shall not affect the validity of the proceedings for the
redemption of any other such Note or portion thereof.

     Any notice that is mailed to the Holders of Registered Notes in the manner
herein provided shall be conclusively presumed to have been duly given, whether
or not the Holder receives the notice.

     All notices of redemption shall state:

          (1) the Redemption Date,

          (2) the Redemption Price, accrued interest to the Redemption Date
     payable as provided in Section 1106, if any, and Additional Amounts, if
     any,

          (3) if less than all Outstanding Notes of any series are to be
     redeemed, the identification (and, in the case of partial redemption, the
     principal amount) of the particular Note or Notes to be redeemed,

          (4) in case any Note is to be redeemed in part only, the notice which
     relates to such Note shall state that on and after the Redemption Date,
     upon surrender of such Note, the holder


<PAGE>


     will receive, without a charge, a new Note or Notes of authorized
     denominations for the principal amount thereof remaining unredeemed,

          (5) that on the Redemption Date the Redemption Price and accrued
     interest to the Redemption Date payable as provided in Section 1106, if
     any, will become due and payable upon each such Note, or the portion
     thereof, to be redeemed and, if applicable, that interest thereon shall
     cease to accrue on and after said date,

          (6) the Place or Places of Payment where such Notes maturing after the
     Redemption Date, are to be surrendered for payment of the Redemption Price,

          (7) that the redemption is for a sinking fund, if such is that case,

          (8) the CUSIP number of such Note, and

          (9) that such securities will cease to accrue interest after the
     Redemption Date.

     Notice of redemption of Notes to be redeemed shall be given by the Company
or, at the Company's request, may be given by the Trustee in the name and at the
expense of the Company.

     SECTION 1105. Deposit of Redemption Price. At least one Business Day prior
to any Redemption Date, the Company shall deposit with the Trustee or with a
Paying Agent (or, if the Company is acting as its own Paying Agent, segregate
and hold in trust as provided in Section 1003) an amount of money sufficient to
pay on the Redemption Date the Redemption Price of, and (except if the
Redemption Date shall be an Interest Payment Date) accrued interest on, all of
the Notes or portions thereof which are to be redeemed on that date.

     SECTION 1106. Notes Payable on Redemption Date. Notice of redemption having
been given as aforesaid, the Notes so to be redeemed shall, on the Redemption
Date, become due and payable at the Redemption Price, and from and after such
date (unless the Company shall default in the payment of the Redemption Price)
such Notes shall, if the same were interest-bearing, cease to bear interest.
Upon surrender of any such Note for redemption in accordance with said notice,
such Note shall be paid by the Company at the Redemption Price; provided,
however, that installments of interest on Registered Notes whose Stated Maturity
is on or prior to the Redemption Date shall be payable to the Holders of such
Notes, or one or more Predecessor Notes, registered as such at the close of
business on the relevant Record Dates according to their terms and the
provisions of Section 307.

     Subject to Section 1113, if any Note called for redemption shall not be so
paid upon surrender thereof for redemption, the principal (and premium or
Make-Whole Amount, if any) shall, until paid, bear interest from the Redemption
Date at the rate borne by the Note.

     SECTION 1107. Notes Redeemed in Part. Any Registered Note which is to be
redeemed only in part (pursuant to the provisions of this Article) shall be
surrendered at a Place of Payment therefor (with, if the Company or the Trustee
so requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Company and the Trustee duly executed by, the


<PAGE>


Holder thereof or his or her attorney duly authorized in writing) and the
Company shall execute and the Trustee shall authenticate and deliver to the
Holder of such Note without service charge a new Note or Notes of the same
series, of any authorized denomination as requested by such Holder in aggregate
principal amount equal to and in exchange for the unredeemed portion of the
principal of the Note so surrendered.


                                   ARTICLE XII

                                    GUARANTY

     SECTION 1201. Guaranty. The Guarantor, as primary obligor and not merely as
surety, hereby irrevocably and unconditionally guarantees to each Holder and to
the Trustee and its successors and assigns (a) the full and punctual payment
when due, whether at Stated Maturity, by acceleration or otherwise, of all
obligations of the Company now or hereafter existing under this Indenture
whether for principal of or interest on the Notes, (and premium and Make-Whole
Amount if any) and all other monetary obligations of the Company under this
Indenture and the Notes in respect of the Notes and (b) the full and punctual
performance within the applicable grace periods of all other obligations of the
Company under this Indenture and the Notes (all such obligations guaranteed
hereby by the Guarantor being the "Guaranteed Obligations"). The guaranty of the
Guarantor under this Article 12 is herein referred to as this "Guaranty".

     The Guarantor agrees to pay any and all fees and expenses (including
reasonable attorney's fees and expenses) incurred by the Trustee or the Holders
in enforcing any rights under this Article 12 with respect to the Guarantor.

     Without limiting the generality of the foregoing, this Guaranty guarantees,
to the extent provided herein, the payment of all amounts which constitute part
of the Guaranteed Obligations and would be owed by the Company under this
Indenture or the Notes but for the fact that they are unenforceable or not
allowable due to the existence of a bankruptcy, reorganization or similar
proceeding involving the Company.

     SECTION 1202. Guaranty Absolute. This Guaranty is irrevocable, absolute and
unconditional. The Guarantor guarantees that the Guaranteed Obligations will be
performed strictly in accordance with the terms of this Indenture, regardless of
any law, regulation or order now or hereafter in effect in any jurisdiction
affecting any of such terms or the rights of the Trustee or the Holders with
respect thereto. The obligations of the Guarantor under this Guaranty are
independent of the Guaranteed Obligations, and a separate action or actions may
be brought and prosecuted against the Guarantor to enforce this Guaranty,
irrespective of whether any action is brought against the Company or any other
guarantor or whether the Company or any other guarantor is joined in any such
action or actions. The liability of the Guarantor under this Guaranty shall be
absolute and unconditional irrespective of:

          (a) any lack of validity or enforceability of this Indenture or the
     Notes with respect to the Company or any agreement or instrument relating
     thereto;


<PAGE>


          (b) any change in the time, manner or place of payment of, or in any
     other term of any of the Guaranteed Obligations, or any other amendment or
     waiver of or any consent to departure from this Indenture;

          (c) the failure to give notice to the Guarantor of the occurrence of a
     default under the provisions of this Indenture or the Notes;

          (d) any taking, release or amendment or waiver of or consent to
     departure from any other guaranty, for all or any of the Guaranteed
     Obligations;

          (e) any failure, omission, delay by or inability on the part of the
     Trustee or the Holders to assert or exercise any right, power or remedy
     conferred on the Trustee or the Holders in this Indenture or the Notes;

          (f) any change in the corporate or other structure, or termination,
     dissolution, consolidation or merger of the Company or the Guarantor with
     or into any other entity, the voluntary or involuntary liquidation,
     dissolution, sale or other disposition of all or substantially all the
     assets of the Company or the Guarantor, the marshaling of the assets and
     liabilities of the Company or the Guarantor, the receivership, insolvency,
     bankruptcy, assignment for the benefit of creditors, reorganization,
     arrangement, composition with creditors, or readjustments of, or other
     similar proceedings affecting the Company or the Guarantor, or any of the
     assets of any of them;

          (g) the assignment of any right, title or interest of the Trustee or
     any Holder in this Indenture or the Notes to any other Person; or

          (h) any other event or circumstance (including any statute of
     limitations), whether foreseen or unforeseen and whether similar or
     dissimilar to any of the foregoing, that might otherwise constitute a
     defense available to, or a discharge of, the Company or the Guarantor,
     other than performance in full of the Guaranteed Obligations for the
     payment of money; it being the intent of the Guarantor that its obligations
     hereunder shall not be discharged except by payment of all amounts owing
     pursuant to this Indenture or the Notes.

     This Guaranty shall continue to be effective or be reinstated, as the case
may be, if at any time any payment or performance with respect to any of the
Guaranteed Obligations is rescinded or must otherwise be returned by the
Trustee, any Holder or any other Person upon the insolvency, bankruptcy or
reorganization of the Company or otherwise, all as though such payment or
performance had not been made or occurred. The obligations of the Guarantor
under this Guaranty shall not be subject to reduction, termination or other
impairment by any set-off, recoupment, counterclaim or defense or for any other
reason.


<PAGE>

     SECTION 1203. Waivers. The Guarantor hereby irrevocably waives, to the
extent permitted by applicable law:

          (a) promptness, diligence, notice of acceptance and any other notice
     with respect to any of the Guaranteed Obligations and this Guaranty;

          (b) any requirement that the Trustee, any Holder or any other Person
     protect, secure, perfect or insure any Encumbrance or any property subject
     thereto or exhaust any right or take any action against the Company or any
     other Person, or obtain any relief pursuant to this Indenture or pursue any
     other available remedy;

          (c) all right to trial by jury in any action, proceeding or
     counterclaim arising out of or relating to this Indenture or the Notes;

          (d) any defense arising by reason of any claim or defense based upon
     an election of remedies by the Trustee or any Holder which in any manner
     impairs, reduces, releases or otherwise adversely affects its subrogation,
     contribution or reimbursement rights or other rights to proceed against the
     Company or any other Person; and

          (e) any duty on the part of the Trustee or any Holder to disclose to
     the Guarantor any matter, fact or thing relating to the business, operation
     or condition of the Company and its assets now known or hereafter known by
     the Trustee or such Holder.

     SECTION 1204. Waiver of Subrogation and Contribution. Until this Indenture
has been discharged, the Guarantor hereby irrevocably waives any claim or other
right which it may now or hereafter acquire against the Company or any guarantor
that arise from the existence, payment, performance or enforcement of the
Guarantor's obligations under this Guaranty, including any right of subrogation,
reimbursement, exoneration, contribution, indemnification, any right to
participate in any claim or remedy of the Trustee or any Holder against the
Company or any guarantor which the Trustee or any Holder now has or hereafter
acquires, whether or not such claim, remedy or right arises in equity, or under
contract, statute or common law, including the right to take or receive from the
Company, directly or indirectly, in cash or other property or by setoff or in
any other manner, payment or security on account of such claim or other rights.
If any amount shall be paid to the Guarantor in violation of the preceding
sentence and the Guaranteed Obligations shall not have been paid in full, such
amount shall be deemed to have been paid to the Guarantor for the benefit of,
and held in trust for the benefit of, the Trustee, and the Holders, and shall
forthwith be paid to the Trustee for the benefit of the Holders to be credited
and applied to the Guaranteed Obligations, whether matured or unmatured, in
accordance with the terms of this Indenture. The Guarantor acknowledges that it
will receive direct and indirect benefits from the financing arrangements
contemplated by this Indenture and that the waivers set forth in this Section
1204 are knowingly made in contemplation of such benefits.

     The Guarantor agrees that it shall not be entitled to any right of
subrogation in relation to the Holders in respect of any obligations guaranteed
hereby until payment in full of all obligations guaranteed hereby. The Guarantor
further agrees that, as between itself, on the one hand, and the Holders and the
Trustee, on the other hand, (x) the maturity of the obligations guaranteed
hereby may be accelerated as provided in Article 5 hereof for the purposes of
this Guaranty, notwithstanding any stay, injunction or other prohibition
preventing such acceleration in respect of the obligations guaranteed hereby,
and (y) in the event of any declaration of acceleration of such obligations as


<PAGE>


provided in Article 5 hereof, such obligations (whether or not due and payable)
shall forthwith become due and payable by the Guarantor for the purpose of this
Guaranty.

     SECTION 1205. Certain Agreements. The Guarantor covenants and agrees that,
as a condition to the acceptability of this Guaranty to the Trustee and the
Holders, the Guarantor will:

          (a) comply in all material respects with all applicable laws, rules,
     regulations and orders, such compliance to include paying when due all
     taxes, assessments and governmental charges imposed upon it or upon its
     property except to the extent contested in good faith; and

          (b) preserve and maintain its existence, rights (contractual and
     statutory) and franchises; provided, however, that the Guarantor shall not
     be required to preserve any right or franchise if the general partner of
     the Guarantor shall determine that the preservation thereof is no longer
     desirable in the conduct of the business of the Guarantor and the loss
     thereof is not disadvantageous in any material respect to the Guarantor or
     the Holders.

          (c) not consolidate with or merge with or into (whether or not such
     Guarantor is the surviving Person) another Person whether or not affiliated
     with such Guarantor unless:

               (i) the Person formed by or surviving any such consolidation or
          merger (if other than a Guarantor or the Company) unconditionally
          assumes all the obligations of the Guarantor, pursuant to a
          supplemental indenture in form and substance satisfactory to the
          Trustee, under the Notes, the Indenture and the Guaranty on the terms
          set forth herein or therein; and

               (ii) immediately after giving effect to such transaction, no
          default or Event of Default exists.


     Any such consolidation, merger, sale, lease or conveyance is subject to
the condition that the Trustee receive an Officers' Certificate of the Guarantor
and an Opinion of Counsel to the effect that the merger, sale, lease or
conveyance, and the assumption by any successor entity, complies with the
provisions of this Article and that all conditions precedent herein provided for
relating to such transactions have been complied with.


     In case of any such consolidation, merger, sale or conveyance and upon the
assumption by the successor Person, by supplemental indenture, executed and
delivered to the Trustee and satisfactory in form to the Trustee, of the
Guaranty endorsed upon the Notes and the due and punctual performance of all of
the covenants and conditions of this Indenture to be performed by the Guarantor,
such successor Person shall succeed to and be substituted for the Guarantor with
the same effect as if it had been named herein as a Guarantor. The Guaranty
shall in all respects have the same legal rank and benefit under this Indenture
theretofore and thereafter issued in accordance with the terms of this Indenture
as though such Guaranty had been issued at the date of the execution hereof.

     Except as set forth in Articles 8 and 10 hereof, and notwithstanding
clauses (a) and (b) above, nothing contained in this Indenture or in any of the
Notes shall prevent any consolidation or merger of the Guarantor with or into
the Company or shall prevent any sale or conveyance of the property of the
Guarantor as an entirety or substantially as an entirety to the Company.


<PAGE>

     SECTION 1206. No Waiver; Cumulative Remedies. No failure on the part of the
Trustee or any Holder to exercise, and no delay in exercising, any right
hereunder shall operate as a waiver thereof; nor shall any single or partial
exercise of any right hereunder preclude any other or further exercise thereof
or the exercise of any other right. The remedies herein provided are cumulative
and not exclusive of any remedies provided by law. The Trustee and the Holders
shall have all of the rights and remedies granted in this Indenture and
available at law or in equity, and these same rights and remedies may be pursued
separately, successively or concurrently against the Company or the Guarantor.

     SECTION 1207. Continuing Guaranty. The Guaranty is a continuing guaranty
and, except as otherwise provided herein, shall (a) remain in full force and
effect until the satisfaction of the Guaranteed Obligations, (b) be binding upon
the Guarantor and (c) enure to the benefit of and be enforceable by the Trustee,
the Holders and their successors, transferees and assigns.

     SECTION 1208. Severability. Any provisions of this Article 12 which is
prohibited, unenforceable or not authorized in any jurisdiction shall, as to
such jurisdiction, be ineffective to the extent of such prohibition,
unenforceability or non-authorization, without invalidating the remaining
provisions hereof or affecting the validity, enforceability or legality of such
provision in any other jurisdiction.

     SECTION 1209. Limitation on Guarantor Liability. The Guarantor, and by its
acceptance hereof, each Holder, hereby confirms that it is the intention of all
such parties that the guaranty by such Guarantor pursuant to its Guaranty not
constitute a fraudulent transfer or conveyance for purposes of the Bankruptcy
Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act
or any similar federal or state law. To effectuate the foregoing intention, the
Holders and the Guarantor hereby irrevocably agree that the obligations of such
Guarantor under this Article 12 shall be limited to the maximum amount as will,
after giving effect to all other contingent and fixed liabilities of such
Guarantor that are relevant under such laws and after giving effect to any
collections from or payments made by or on behalf of any other Guarantor in
respect of the obligations of such other Guarantor under this Article 12, if
any, result in the obligations of the Guarantor under the Guaranty not
constituting a fraudulent transfer or conveyance.


                                  ARTICLE XIII

                                    [OMITTED]


                                   ARTICLE XIV

                       DEFEASANCE AND COVENANT DEFEASANCE

     SECTION 1401. Applicability of Article; Company's Option to Effect
Defeasance or Covenant Defeasance. The provisions of this Article shall be
applicable to the Notes, and the Company may at its option by Board Resolution,
at any time, with respect to the Notes, elect to have Section 1402 or Section
1403 applied to such Outstanding Notes upon compliance with the conditions set
forth below in this Article.


<PAGE>


     SECTION 1402. Defeasance and Discharge. Upon the Company's exercise of the
above option applicable to this Section with respect to any Notes of or within a
series, the Company shall be deemed to have been discharged from its obligations
with respect to such Outstanding Notes on the date the conditions set forth in
Section 1404 are satisfied (hereinafter, "defeasance"). For this purpose, such
defeasance means that the Company shall be deemed to have paid and discharged
the entire indebtedness represented by such Outstanding Notes, which shall
thereafter be deemed to be "Outstanding" only for the purposes of Section 1405
and the other Sections of this Indenture referred to in clauses (A) and (B)
below, and to have satisfied all of its other obligations under such Notes and
this Indenture insofar as such Notes are concerned (and the Trustee, at the
expense of the Company, shall execute proper instruments acknowledging the
same), except for the following which shall survive until otherwise terminated
or discharged hereunder: (A) the rights of Holders of such Outstanding Notes to
receive, solely from the trust fund described in Section 1404 and as more fully
set forth in such Section, payments in respect of the principal of (and premium
or Make-Whole Amount, if any) and interest, if any, on such Notes appertaining
thereto when such payments are due, (B) the Company's obligations with respect
to such Notes under Sections 305, 306, 1002 and 1003 and with respect to the
payment of Additional Amounts, if any, on such Notes as contemplated by Section
1012, (C) the rights, powers, trusts, duties and immunities of the Trustee
hereunder, including Section 606 and (D) this Article. Subject to compliance
with this Article Fourteen, the Company may exercise its option under this
Section notwithstanding the prior exercise of its option under Section 1403 with
respect to such Notes.

     SECTION 1403. Covenant Defeasance. Upon the Company's exercise of the above
option applicable to this Section with respect to any Notes, the Company shall
be released from its obligations under Sections 1004 to 1010, inclusive, with
respect to such Outstanding Notes on and after the date the conditions set forth
in Section 1404 are satisfied (hereinafter, "covenant defeasance"), and such
Notes shall thereafter be deemed to be not "Outstanding" for the purposes of any
direction, waiver, consent or declaration or Act of Holders (and the
consequences of any thereof) in connection with Sections 1004 to 1010,
inclusive, but shall continue to be deemed "Outstanding" for all other purposes
hereunder. For this purpose, such covenant defeasance means that, with respect
to such Outstanding Notes, the Company may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth in any such
Section or such other covenant, whether directly or indirectly, by reason of any
reference elsewhere herein to any such Section or such other covenant or by
reason of reference in any Section or such other covenant to any other provision
herein or in any other document and such omission to comply shall not constitute
a default or an Event of Default under Section 501(6) but, except as specified
above, the remainder of this Indenture and such Notes shall be unaffected
thereby.

     SECTION 1404. Conditions to Defeasance or Covenant Defeasance. The
following shall be the conditions to application of Section 1402 or Section 1403
to any Outstanding Notes of or within a series:

          (a) The Company shall irrevocably have deposited or caused to be
     deposited with the Trustee (or another trustee satisfying the requirements
     of Section 607 who shall agree to comply with the provisions of this
     Article 14 applicable to it) as trust funds in trust for the purpose of
     making the following payments, specifically pledged as security for, and
     dedicated solely to, the benefit of the


<PAGE>


     Holders of such Notes, (1) an amount of money or (2) Government Obligations
     applicable to such Notes which through the scheduled payment of principal
     and interest in respect thereof in accordance with the terms will provide,
     not later than one day before the due date of any payment of principal of
     and premium or Make-Whole Amount, if any and interest on such Notes, money
     in an amount, or (3) a combination thereof, any case, in an amount
     sufficient, without consideration of any reinvestment of such principal and
     interest, in the opinion of a nationally recognized firm of independent
     public accountants expressed in a written certification thereof delivered
     the Trustee, to pay and discharge, and which shall be applied by the
     Trustee (or other qualifying trustee) to pay and discharge, the principal
     of (and premium or Make-Whole Amount, if any), and interest on such
     Outstanding Notes on the Stated Maturity of such principal or installment
     of principal or interest or analogous payments applicable to such
     Outstanding Notes on the day on which such payments are due and payable in
     accordance with the terms of this Indenture and of such Notes.

          (b) Such defeasance or covenant defeasance shall not result in a
     breach or violation of, or constitute a default under, this Indenture or
     any other material agreement or instrument to which the Company is a party
     or by which it is bound.

          (c) No Event of Default or event which with notice or lapse of time or
     both would become an Event of Default with respect to such Notes shall have
     occurred and be continuing on the date of such deposit or, insofar as
     Sections 501(5) and 501(6) are concerned, at any time during the period
     ending on the 91st day after the date of such deposit (it being understood
     that this condition shall not be deemed satisfied until the expiration of
     such period).

          (d) In the case of an election under Section 1402, the Company shall
     have delivered to the Trustee an Opinion of Counsel stating that (i) the
     Company has received from, or there has been published by, the Internal
     Revenue Service a ruling, or (ii) since the date of execution of this
     Indenture, there has been a change in the applicable Federal income tax
     law, in either case to the effect that, and based thereon such opinion
     shall confirm that, the Holders of such Outstanding Notes will not
     recognize income, gain or loss for Federal income tax purposes as a result
     of such defeasance and will be subject to Federal income tax on the same
     amounts, in the same manner and at the same times as would have been the
     case if such defeasance had not occurred.

          (e) In the case of an election under Section 1403, the Company shall
     have delivered to the Trustee an Opinion of Counsel to the effect that the
     Holders of such Outstanding Notes will not recognize income, gain or loss
     for Federal income tax purposes as a result of such covenant defeasance and
     will be subject to Federal income tax on the same amounts, in the same
     manner and at the same times as would have been the case if such covenant
     defeasance had not occurred.

          (f) The Company shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel, each stating that all conditions
     precedent to the defeasance under Section 1402 or the covenant defeasance
     under Section 1403 (as the case may be) have been complied with and an
     Opinion of Counsel to the effect that either (i) as a result of a deposit
     pursuant to subsection (a) above and the related exercise of the Company's
     option under Section 1402 or Section 1403 (as the case may be),
     registration is not required under the Investment Company Act of 1940, as
     amended, by the


<PAGE>


     Company with respect to the trust funds representing such deposit or by the
     Trustee for such trust funds or (ii) all necessary registrations under said
     Act have been effected.

          (g) Notwithstanding any other provisions of this Section, such
     defeasance or covenant defeasance shall be effected in compliance with any
     additional or substitute terms, conditions or limitations which may be
     imposed on the Company in connection therewith.

     SECTION 1405. Deposited Money and Government Obligations to be Held in
Trust; Other Miscellaneous Provisions. Subject to the provisions of the last
paragraph of Section 1003, all money and Government Obligations (including the
proceeds thereof) deposited with the Trustee (or other qualifying trustee,
collectively for purposes of this Section 1405, the "Trustee") pursuant to
Section 1404 in respect of any Outstanding Notes of any series shall be held in
trust and applied by the Trustee, in accordance with the provisions of such
Notes and this Indenture, to the payment, either directly or through any Paying
Agent as the Trustee may determine, to the Holders of such Notes of all sums due
and to become due thereon in respect of principal (and premium or Make-Whole
Amount, if any) and interest but such money need not be segregated from other
funds except to the extent required by law.

     The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the Government Obligations deposited
pursuant to Section 1404 or the principal and interest received in respect
thereof other than any such tax, fee or other charge which by law is for the
account of the Holders of such Outstanding Notes.

     Anything in this Article to the contrary notwithstanding, subject to
Section 606, the Trustee shall deliver or pay to the Company from time to time
upon the Company Request any money or Government Obligations (or other property
and any proceeds therefrom) held by it as provided in Section 1404 which, in the
opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, are in
excess of the amount thereof which would then be required to be deposited to
effect a defeasance or covenant defeasance, as applicable, in accordance with
this Article.

<PAGE>

Notes of such series for any purpose specified in Section 1501, by written
request setting forth in reasonable detail the action proposed to be taken at
the meeting, and the Trustee shall not have made the first publication of the
notice of such meeting within 21 days after receipt of such request or shall not
thereafter proceed to cause the meeting to be held as provided herein, then the
Company or the Holders of Notes of such series in the amount above specified, as
the case may be, may determine the time and the place for such meeting and may
call such meeting for such purposes by giving notice thereof as provided in
subsection (a) of this Section.

     SECTION 1503. Persons Entitled to Vote at Meetings. To be entitled to vote

outstanding Notes of such series by such Holder or Holders. The only Persons who
shall be entitled to be present or to speak at any meeting of Holders of Notes
of any series shall be the Persons entitled to vote at such meeting and their

any adjourned meeting shall state expressly the percentage, as provided above,

as aforesaid may be adopted by the affirmative vote of the Holders of a majority
in principal amount of the Outstanding Notes of that series; provided, however,
that, except as limited by the proviso to Section 902, any resolution with
respect to any request, demand, authorization, direction, notice, consent,
waiver or other Act which this Indenture expressly provides may be made, given
or taken by the Holders of a specific percentage,


<PAGE>


that is less than a majority in principal amount of the Outstanding Notes of a
series may be adopted at a meeting or an adjourned meeting duly reconvened and
at which a quorum is present as aforesaid by the affirmative vote of the Holders
of such specified percentage in principal amount of the Outstanding Notes of
that series.

     Any resolution passed or decision taken at any meeting of Holders of Notes
of any series duly held in accordance with this Section shall be binding on all
of the Holders of Notes of such series, whether or not present or represented at
the meeting.

     Notwithstanding the foregoing provisions of this Section 1504, if any
action is to be taken at a meeting of Holders of Notes of any series with
respect to any request, demand, authorization, direction, notice, consent,
waiver or other act that this Indenture expressly provides may be made, given or
taken by the Holders of a specified percentage in principal amount of all
Outstanding Notes affected thereby, or of the Holders of such series and one or
more additional series:

          (i) there shall be no minimum quorum requirement for such meeting; and

          (ii) the principal amount of the Outstanding Notes of such series that
     vote in favor of such request, demand, authorization, direction, notice,
     consent, waiver or other action shall be taken into account in determining
     whether such request, demand, authorization, direction, notice, consent,
     waiver or other action has been made, given or taken under this Indenture.

     SECTION 1505. Determination of Voting Rights; Conduct and Adjournment of
Meetings. (a) Notwithstanding any provisions of this Indenture, the Trustee may
make such reasonable regulations as it may deem advisable for any meeting of
Holders of Notes of a series in regard to proof of the holding of Notes of such
series and of the appointment of proxies and in regard to the appointment and
duties of inspectors of votes, the submission and examination of proxies,
certificates and other evidence of the right to vote, and such other matters
concerning the conduct of the meeting as it shall deem appropriate. Except as
otherwise permitted or required by any such regulations, the holding of Notes
shall be proved in the manner specified in Section 104 and the appointment of
any proxy shall be proved in the manner specified in Section 104. Such
regulations may provide that written instruments appointing proxies, regular on
their face, may be presumed valid and genuine without the proof specified in
Section 104 or other proof.

     (b) The Trustee shall, by an instrument in writing appoint a temporary
chairman of the meeting, unless the meeting shall have been called by the
Company or by Holders of Notes provided in Section 1502(b), in which case the
Company or the Holders of Notes of the series calling the meeting, as the case
may be, shall in like manner appoint a temporary chairman. A permanent chairman
and a permanent secretary of the meeting shall be elected by vote of the Persons
entitled to vote a majority in principal amount of the Outstanding Notes of such
series represented at the meeting.

     (c) At any meeting each Holder of a Note of such series or proxy shall be
entitled to one vote for each $1,000 principal amount of the Outstanding Notes
of such series held or represented by him; provided, however, that no vote shall
be cast or counted at any meeting in respect of any Note challenged as not
Outstanding and ruled by the chairman of the meeting to be not


<PAGE>


Outstanding. The chairman of the meeting shall have no right to vote, except as
a Holder of a Note of such series or proxy.

     (d) Any meeting of Holders of Notes of any series duly called pursuant to
Section 1502 at which a quorum is present may be adjourned from time to time by
Persons entitled to vote a majority in principal amount of the Outstanding Notes
of such series represented at the meeting, and the meeting may be held as so
adjourned without further notice.

     SECTION 1506. Counting Votes and Recording Action of Meetings. The vote
upon any resolution submitted to any meeting of Holders of Notes of any series
shall be by written ballots on which shall be subscribed the signatures of the
Holders of Notes of such series or of their representatives by proxy and the
principal amounts and serial numbers of the Outstanding Notes of such series
held or represented by them. The permanent chairman of the meeting shall appoint
two inspectors of votes who shall count all votes cast at the meeting for or
against any resolution and who shall make and file with the secretary of the
meeting their verified written reports in duplicate of all votes cast at the
meeting. A record, at least in duplicate, of the proceedings of each meeting of
Holders of Notes of any Series shall be prepared by the secretary of the meeting
and there shall be attached to said record the original reports of the
inspectors of votes on any vote by ballot taken thereat and affidavits by one or
more persons having knowledge of the fact, setting forth a copy of the notice of
the meeting and showing that said notice was given as provided in Section 1502
and, if applicable, Section 1504. Each copy shall be signed and verified by the
affidavits of the permanent chairman and secretary of meeting and one such copy
shall be delivered to the Company and another to the Trustee to be preserved by
the Trustee, the latter to have attached thereto the ballots voted at the
meeting. Any record so signed and verified shall be conclusive evidence of the
matters therein stated.

     SECTION 1507. Evidence of Action Taken by Holders. Any request, demand,
authorization, direction, notice, consent, waiver or other Act provided by this
Indenture to be given or taken by a specified percentage in principal amount of
the Holders of any or all series may be embodied in and evidenced by one or more
instruments of substantially similar tenor signed by such specified percentage
of Holders in person or by an agent duly appointed in writing; and, except as
herein otherwise expressly provided, such Act shall become effective when such
instrument or instruments are delivered to the Trustee. Proof and execution of
any instrument or of a writing appointing any such agent shall be sufficient for
any purpose of this Indenture and (subject to Article 6) conclusive in favor of
the Trustee and the Company, if made in the manner provided in this Article.

     SECTION 1508. Proof of Execution of Instruments. Subject to Article 6, the
execution of any instrument by a Holder or his or her agent or proxy may be
proved in accordance with such reasonable rules and regulations as may be
prescribed by the Trustee or in manner as shall be satisfactory to the Trustee.

so executed shall be deemed to be an original, but all such counterparts shall

                               6.625% NOTE DUE 2005


     CARRAMERICA REALTY CORPORATION, a corporation duly organized and existing
under the laws of the State of Maryland (herein referred to as the "Company"
which term shall include any successor corporation under the Indenture
hereinafter referred to), for value received, hereby promises to pay to
_________________ or registered assigns, upon presentation, the principal sum of
__________________ on March 1, 2005 and to pay interest on the outstanding
principal amount thereon from February 23, 1998, or from the immediately
preceding Interest Payment Date to which interest has been paid or duly provided
for, semi-annually in arrears on March 1 and September 1 in each year,
commencing September 1, 1998, at the rate of 6.625% per annum, until the entire
principal hereof is paid or made available for payment; provided, however, that
if the Company or the Guarantor fail to fulfill their obligations in accordance
with and under the Registration Rights Agreement, additional interest will
accrue on this Note at the rate and to the extent set forth in the Registration
Rights Agreement. The interest so payable and punctually paid or duly provided
for on any Interest Payment Date will, as provided in the Indenture, be paid to
the Person in whose name this Note is registered at


<PAGE>


the close of business on the Regular Record Date for such interest which shall
be the February 15 or August 15 (whether or not a Business Day), as the case may
be, next preceding such Interest Payment Date. Any such interest not so
punctually paid or duly provided for shall forthwith cease to be payable to the
Holder on such Regular Record Date, and may either be paid to the Person in
whose name this Note is registered at the close of business on a Special Record
Date for the payment of such defaulted interest to be fixed by the Trustee,
notice whereof shall be given to Holders of the Notes not more than 15 days and
not less than 10 days prior to such Special Record Date, or may be paid at any
time in any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Notes may be listed, and upon such notice as
may be required by such exchange, all as more fully provided in the Indenture.
Payment of the principal of and interest on this Note will be made at the office
or agency maintained for that purpose in the City of New York, New York, or
elsewhere as provided in the Indenture, in such coin or currency of the United
States of America as at the time of payment is legal tender for payment of
public and private debts; provided, however, that at the option of the Company
payments of principal and interest on the Notes (other than payments of
principal and interest due at Maturity) may be made by check mailed to the
address of the Person entitled thereto as such address shall appear in the
Security Register.

     Notes of this series are one of a duly authorized issue of securities of
the Company (herein called the "Notes"), issued and to be issued in one or more
series under an Indenture, dated as of February 23, 1998 (the "Indenture"),
among the Company, CarrAmerica Realty, L.P., as Guarantor (herein called the
"Guarantor"), and Banker Trust Company (herein called the "Trustee," which term
includes any successor trustee under the Indenture), to which Indenture and all
indentures supplemental thereto reference is hereby made for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of
the Company, the Guarantor, the Trustee and the Holders of the Notes and of the
terms upon which the Notes are authenticated and delivered. This Note is one of
the series designated therein.

     Notes of this series may be redeemed at any time at the option of the
Company, in whole or in part, upon notice of not more than 60 nor less than 30
days prior to the Redemption Date, at a redemption price equal to the sum of (i)
the principal amount of the Notes being redeemed plus accrued interest thereon
to the Redemption Date and (ii) the Make-Whole Amount, if any, with respect to
such Notes.

     The Indenture contains provisions for defeasance at any time of (a) the
entire indebtedness of the Company on this Note and (b) certain restrictive
covenants and the related defaults and Events of Default applicable to the
Company, in each case, upon compliance by the Company with certain conditions
set forth in the Indenture, which provisions apply to this Note.

     If an Event of Default with respect to the Notes shall occur and be
continuing, the principal of the Notes may be declared due and payable in the
manner and with the effect provided in the Indenture.

     As provided in and subject to the provisions of the Indenture, the Holder
of this Note shall not have the right to institute any proceeding with respect
to the Indenture or for the appointment of a receiver or trustee or for any
other remedy thereunder, unless such Holder shall have previously


<PAGE>


given written notice to the Trustee of a continuing Event of Default with
respect to the Notes, the Holders of not less than 25% in principal amount of
the Notes of this series at the time Outstanding shall have made written request
to the Trustee to institute proceedings in respect of such Event of Default as
Trustee and offered the Trustee reasonable indemnity and the Trustee shall not
have received from the Holders of a majority in principal amount of Notes of
this series at the time Outstanding a direction inconsistent with such request,
and shall have failed to institute any such proceeding, for 60 days after
receipt of such notice, request and offer of indemnity. The foregoing shall not
apply to any suit instituted by the Holder of this Note for the enforcement of
any payment of principal hereof or any interest on or after the respective due
dates expressed herein.

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Notes of each series to be affected
under the Indenture at any time by the Company and the Trustee with the consent
of the Holders of not less than a majority in principal amount of the
Outstanding Notes of each series of Notes then Outstanding affected thereby. The
Indenture also contains provisions permitting the Holders of specified
percentages in principal amount of the Notes of each series at the time
Outstanding, on behalf of the Holders of all Notes of such series, to waive
compliance by the Company with certain provisions of the Indenture and certain
past defaults under the Indenture and their consequences. Any such consent or
waiver by the Holder of this Note shall be conclusive and binding upon such
Holder and upon all future Holders of this Note and of any Note issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Note.

     No reference herein to the Indenture and no provision of this Note or of
the Indenture shall alter or impair (i) the obligation of the Company, which is
absolute and unconditional, to pay the principal of (and Make-Whole Amount, if
any) and interest on this Note at the times, place and rate, and in the coin or
currency, herein prescribed, or (ii) the obligations of the Guarantor, which are
unconditional, in respect of the Guaranteed Obligations.

     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Note is registrable in the Security Register, upon
surrender of this Note for registration of transfer at the office or agency of
the Company in any Place of Payment where the principal of (and Make-Whole
Amount, if any, on) and interest on this Note are payable, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed by the Holder hereof or his or
her attorney duly authorized in writing, and thereupon one or more new Notes of
this series, of authorized denominations and for the same aggregate principal
amount, will be issued to the designated transferee or transferees.

     The Notes of this series are issuable only in registered form in
denominations of $1,000 and any integral multiple thereof. As provided in the
Indenture and subject to certain limitations therein set forth, Notes of this
series are exchangeable for a like aggregate principal amount of Notes of this
series of a different authorized denomination, as requested by the Holder
surrendering the same.


<PAGE>


     No service charge shall be made for any such registration of transfer or

                              6.875% NOTE DUE 2008


     CARRAMERICA REALTY CORPORATION, a corporation duly organized and existing
under the laws of the State of Maryland (herein referred to as the "Company"
which term shall include any successor corporation under the Indenture
hereinafter referred to), for value received, hereby promises to pay to
_________________ or registered assigns, upon presentation, the principal sum of
__________________ on March 1, 2008 and to pay interest on the outstanding
principal amount thereon from February 23, 1998, or from the immediately
preceding Interest Payment Date to which interest has been paid or duly provided
for, semi-annually in arrears on March 1 and September 1 in each year,
commencing September 1, 1998, at the rate of 6.875% per annum, until the entire
principal hereof is paid or made available for payment; provided, however, that
if the Company or the Guarantor fail to fulfill their obligations in accordance
with and under the Registration Rights Agreement, additional interest will
accrue on this note at the rate and to the extent set forth in the Registration
Rights Agreement. The interest so payable and punctually paid or duly provided
for on any Interest Payment Date will, as provided in the Indenture, be paid to
the Person in whose name this Note is registered at the close of business on the
Regular Record Date for such interest which shall be the February 15 or August
15


<PAGE>


(whether or not a Business Day), as the case may be, next preceding such
Interest Payment Date. Any such interest not so punctually paid or duly provided
for shall forthwith cease to be payable to the Holder on such Regular Record
Date, and may either be paid to the Person in whose name this Note is registered
at the close of business on a Special Record Date for the payment of such
defaulted interest to be fixed by the Trustee, notice whereof shall be given to
Holders of the Notes not more than 15 days and not less than 10 days prior to
such Special Record Date, or may be paid at any time in any other lawful manner
not inconsistent with the requirements of any securities exchange on which the
Notes may be listed, and upon such notice as may be required by such exchange,
all as more fully provided in the Indenture. Payment of the principal of and
interest on this Note will be made at the office or agency maintained for that
purpose in the City of New York, New York, or elsewhere as provided in the
Indenture, in such coin or currency of the United States of America as at the
time of payment is legal tender for payment of public and private debts;
provided, however, that at the option of the Company payments of principal and
interest on the Notes (other than payments of principal and interest due at
Maturity) may be made by check mailed to the address of the Person entitled
thereto as such address shall appear in the Security Register.

     Notes of this series are one of a duly authorized issue of securities of
the Company (herein called the "Notes"), issued and to be issued in one or more
series under an Indenture, dated as of February 23, 1998 (the "Indenture"),
among the Company, CarrAmerica Realty, L.P., as Guarantor (herein called the
"Guarantor"), and Bankers Trust Company (herein called the "Trustee," which term
includes any successor trustee under the Indenture), to which Indenture and all
indentures supplemental thereto reference is hereby made for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of
the Company, the Guarantor, the Trustee and the Holders of the Notes and of the
terms upon which the Notes are authenticated and delivered. This Note is one of
the series designated therein.

     Notes of this series may be redeemed at any time at the option of the
Company, in whole or in part, upon notice of not more than 60 nor less than 30
days prior to the Redemption Date, at a redemption price equal to the sum of (i)
the principal amount of the Notes being redeemed plus accrued interest thereon
to the Redemption Date and (ii) the Make-Whole Amount, if any, with respect to
such Notes.

     The Indenture contains provisions for defeasance at any time of (a) the
entire indebtedness of the Company on this Note and (b) certain restrictive
covenants and the related defaults and Events of Default applicable to the
Company, in each case, upon compliance by the Company with certain conditions
set forth in the Indenture, which provisions apply to this Note.

     If an Event of Default with respect to the Notes shall occur and be
continuing, the principal of the Notes may be declared due and payable in the
manner and with the effect provided in the Indenture.

     As provided in and subject to the provisions of the Indenture, the Holder
of this Note shall not have the right to institute any proceeding with respect
to the Indenture or for the appointment of a receiver or trustee or for any
other remedy thereunder, unless such Holder shall have previously given written
notice to the Trustee of a continuing Event of Default with respect to the
Notes,


<PAGE>


the Holders of not less than 25% in principal amount of the Notes of this series
at the time Outstanding shall have made written request to the Trustee to
institute proceedings in respect of such Event of Default as Trustee and offered
the Trustee reasonable indemnity and the Trustee shall not have received from
the Holders of a majority in principal amount of Notes of this series at the
time Outstanding a direction inconsistent with such request, and shall have
failed to institute any such proceeding, for 60 days after receipt of such
notice, request and offer of indemnity. The foregoing shall not apply to any
suit instituted by the Holder of this Note for the enforcement of any payment of
principal hereof or any interest on or after the respective due dates expressed
herein.

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Notes of each series to be affected
under the Indenture at any time by the Company and the Trustee with the consent
of the Holders of not less than a majority in principal amount of the
Outstanding Notes of each series of Notes then Outstanding affected thereby. The
Indenture also contains provisions permitting the Holders of specified
percentages in principal amount of the Notes of each series at the time
Outstanding, on behalf of the Holders of all Notes of such series, to waive
compliance by the Company with certain provisions of the Indenture and certain
past defaults under the Indenture and their consequences. Any such consent or
waiver by the Holder of this Note shall be conclusive and binding upon such
Holder and upon all future Holders of this Note and of any Note issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Note.

     No reference herein to the Indenture and no provision of this Note or of
the Indenture shall alter or impair (i) the obligation of the Company, which is
absolute and unconditional, to pay the principal of (and Make-Whole Amount, if
any) and interest on this Note at the times, place and rate, and in the coin or
currency, herein prescribed, or (ii) the obligations of the Guarantor, which are
unconditional, in respect of the Guaranteed Obligations.

     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Note is registrable in the Note Register, upon
surrender of this Note for registration of transfer at the office or agency of
the Company in any Place of Payment where the principal of (and Make-Whole
Amount, if any, on) and interest on this Note are payable, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed by the Holder hereof or his or
her attorney duly authorized in writing, and thereupon one or more new Notes of
this series, of authorized denominations and for the same aggregate principal
amount, will be issued to the designated transferee or transferees.

     The Notes of this series are issuable only in registered form in
denominations of $1,000 and any integral multiple thereof. As provided in the
Indenture and subject to certain limitations therein set forth, Notes of this
series are exchangeable for a like aggregate principal amount of Notes of this
series of a different authorized denomination, as requested by the Holder
surrendering the same.

     No service charge shall be made for any such registration of transfer or
exchange, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.


<PAGE>


     Prior to due presentment of this Note for registration of transfer, the
Company, the Guarantor, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Note is registered as the owner hereof
for all purposes, whether or not this Note be overdue, and neither the Company,
the Trustee nor any such agent shall be affected by notice to the contrary.

     No recourse under or upon any obligation, covenant or agreement contained
in the Indenture or in this Note, or because of any indebtedness evidenced
hereby or thereby, shall be had against any promoter, as such, or against any
past, present or future stockholder, officer or director, as such, of the
Company or of any successor, either directly or through the Company or any
successor, under any rule of law, statute or constitutional provision or by the
enforcement of any assessment or by any legal or equitable proceeding or
otherwise, all such liability being expressly waived and released by the
acceptance of this Note by the Holder thereof and as part of the consideration
for the issue of the Notes of this series.

     All capitalized terms used in this Note which are defined in the Indenture
shall have the meanings assigned to them in the Indenture.

     THE INDENTURE AND THE NOTES, INCLUDING THIS NOTE, SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

     Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures, the Company has caused a "CUSIP" number to
be printed on the Notes of this series as a convenience to the Holders of such
Notes. No representation is made as to the correctness or accuracy of such CUSIP
number as printed on the Notes, and reliance may be placed only on the other
identification numbers printed hereon.

     Unless the certificate of authentication hereon has been executed by or on
behalf of the Trustee by manual signature, this Note shall not be entitled to
any benefit under the Indenture or be valid or obligatory for any purpose.

provided in the Indenture, be paid to the Person


<PAGE>


in whose name this Note is registered at the close of business on a Special
Record Date for the payment of such defaulted interest to be fixed by the
Trustee, notice whereof shall be given to Holders of the Notes not more than 15
days and not less than 10 days prior to such Special Record Date, or may be paid
at any time in any other lawful manner not inconsistent with the requirements of
any securities exchange on which the Notes may be listed, and upon such notice
as may be required by such exchange, all as more fully provided in the
Indenture. Payment of the principal of and interest on this Note will be made at
the office or agency maintained for that purpose in the City of New York, New

of public and private debts; provided, however, that at the option of the
Company payments of principal and interest on the Notes (other than payments of
principal and interest due at Maturity) may be made by check mailed to the
address of the Person entitled thereto as such address shall appear in the
Security Register.

     Notes of this series are one of a duly authorized issue of securities of
the Company (herein called the "Notes"), issued and to be issued in one or more
series under an Indenture, dated as of February 23, 1998 (the "Indenture"),
among the Company, CarrAmerica Realty, L.P., as Guarantor (herein called the
"Guarantor"), and Bankers Trust Company (herein called the "Trustee," which term
includes any successor trustee under the Indenture), to which Indenture and all
indentures supplemental thereto reference is hereby made for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of
the Company, the Guarantor, the Trustee and the Holders of the Notes and of the
terms upon which the Notes are authenticated and delivered. This Note is one of
the series designated therein.

     Notes of this series may be redeemed at any time at the option of the
Company, in whole or in part, upon notice of not more than 60 nor less than 30
days prior to the Redemption Date, at a redemption price equal to the sum of (i)
the principal amount of the Notes being redeemed plus accrued interest thereon
to the Redemption Date and (ii) the Make-Whole Amount, if any, with respect to
such Notes.

     The Indenture contains provisions for defeasance at any time of (a) the
entire indebtedness of the Company on this Note and (b) certain restrictive
covenants and the related defaults and Events of Default applicable to the
Company, in each case, upon compliance by the Company with certain conditions
set forth in the Indenture, which provisions apply to this Note.

     If an Event of Default with respect to the Notes shall occur and be
continuing, the principal of the Notes may be declared due and payable in the
manner and with the effect provided in the Indenture.

     As provided in and subject to the provisions of the Indenture, the Holder
of this Note shall not have the right to institute any proceeding with respect
to the Indenture or for the appointment of a receiver or trustee or for any
other remedy thereunder, unless such Holder shall have previously given written
notice to the Trustee of a continuing Event of Default with respect to the
Notes, the Holders of not less than 25% in principal amount of the Notes of this
series at the time Outstanding shall have made written request to the Trustee to
institute proceedings in respect of such Event of Default as Trustee and offered
the Trustee reasonable indemnity and the Trustee shall not have received


<PAGE>


from the Holders of a majority in principal amount of Notes of this series at
the time Outstanding a direction inconsistent with such request, and shall have
failed to institute any such proceeding, for 60 days after receipt of such
notice, request and offer of indemnity. The foregoing shall not apply to any
suit instituted by the Holder of this Note for the enforcement of any payment of
principal hereof or any interest on or after the respective due dates expressed
herein.

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Notes of each series to be affected
under the Indenture at any time by the Company and the Trustee with the consent
of the Holders of not less than a majority in principal amount of the
Outstanding Notes of each series of Notes then Outstanding affected thereby. The
Indenture also contains provisions permitting the Holders of specified
percentages in principal amount of the Notes of each series at the time
Outstanding, on behalf of the Holders of all Notes of such series, to waive
compliance by the Company with certain provisions of the Indenture and certain
past defaults under the Indenture and their consequences. Any such consent or
waiver by the Holder of this Note shall be conclusive and binding upon such
Holder and upon all future Holders of this Note and of any Note issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Note.

     No reference herein to the Indenture and no provision of this Note or of
the Indenture shall alter or impair (i) the obligation of the Company, which is
absolute and unconditional, to pay the principal of (and Make-Whole Amount, if
any) and interest on this Note at the times, place and rate, and in the coin or
currency, herein prescribed, or (ii) the obligations of the Guarantor, which are
unconditional, in respect of the Guaranteed Obligations.

                As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Note is registrable in the Security
Register, upon surrender of this Note for registration of transfer at the office
or agency of the Company in any Place of Payment where the principal of (and
Make-Whole Amount, if any) and interest on this Note are payable, duly endorsed
by, or accompanied by a written instrument of transfer in form satisfactory to
the Company and the Security Registrar duly executed by the Holder hereof or his
attorney duly authorized in writing, and thereupon one or more new Notes of this
series, of authorized denominations and for the same aggregate principal amount,
will be issued to the designated transferee or transferees.

     The Notes of this series are issuable only in registered form in
denominations of $1,000 and any integral multiple thereof. As provided in the
Indenture and subject to certain limitations therein set forth, Notes of this
series are exchangeable for a like aggregate principal amount of Notes of this
series of a different authorized denomination, as requested by the Holder
surrendering the same.

     No service charge shall be made for any such registration of transfer or
exchange, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

     Prior to due presentment of this Note for registration of transfer, the
Company, the Guarantor, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose


<PAGE>


name this Note is registered as the owner hereof for all purposes, whether or
not this Note be overdue, and neither the Company, the Trustee nor any such
agent shall be affected by notice to the contrary.

     No recourse under or upon any obligation, covenant or agreement contained
in the Indenture or in this Note, or because of any indebtedness evidenced
hereby or thereby, shall be had against any promoter, as such, or against any
past, present or future shareholder, officer or director, as such, of the
Company or of any successor, either directly or through the Company or any
successor, under any rule of law, statute or constitutional provision or by the
enforcement of any assessment or by any legal or equitable proceeding or
otherwise, all such liability being expressly waived and released by the
acceptance of this Note by the Holder thereof and as part of the consideration
for the issue of the Notes of this series.

     All capitalized terms used in this Note which are defined in the Indenture
shall have the meanings assigned to them in the Indenture.

     THE INDENTURE AND THE NOTES, INCLUDING THIS NOTE, SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

     Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures, the Company has caused a "CUSIP" number to
be printed on the Notes of this series as a convenience to the Holders of such
Notes. No representation is made as to the correctness or accuracy of such CUSIP
number as printed on the Notes, and reliance may be placed only on the other
identification numbers printed hereon.

     Unless the certificate of authentication hereon has been executed by or on
behalf of the Trustee by manual signature, this Note shall not be entitled to
any benefit under the Indenture or be valid or obligatory for any purpose.

the Company (herein called the "Notes"), issued and to be issued in one or more
series under an Indenture, dated as of February 23, 1998 (the "Indenture"),
among the Company, CarrAmerica Realty, L.P., as Guarantor (herein called the
"Guarantor"), and Bankers Trust Company (herein called the "Trustee," which term
includes any successor trustee under the Indenture), to which Indenture and all
indentures supplemental thereto reference is hereby made for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of
the Company, the Guarantor, the Trustee and the Holders of the Notes and of the
terms upon which the Notes are authenticated and delivered. This Note is one of
the series designated therein.


     Notes of this series may be redeemed at any time at the option of the
Company, in whole or in part, upon notice of not more than 60 nor less than 30
days prior to the Redemption Date, at a redemption price equal to the sum of (i)
the principal amount of the Notes being redeemed plus accrued interest thereon
to the Redemption Date and (ii) the Make-Whole Amount, if any, with respect to
such Notes.

     The Indenture contains provisions for defeasance at any time of (a) the
entire indebtedness of the Company on this Note and (b) certain restrictive
covenants and the related defaults and Events of Default applicable to the
Company, in each case, upon compliance by the Company with certain conditions
set forth in the Indenture, which provisions apply to this Note.

     If an Event of Default with respect to the Notes shall occur and be
continuing, the principal of the Notes may be declared due and payable in the
manner and with the effect provided in the Indenture.

     As provided in and subject to the provisions of the Indenture, the Holder
of this Note shall not have the right to institute any proceeding with respect
to the Indenture or for the appointment of a receiver or trustee or for any
other remedy thereunder, unless such Holder shall have previously given written
notice to the Trustee of a continuing Event of Default with respect to the
Notes, the Holders of not less than 25% in principal amount of the Notes of this
series at the time Outstanding shall have made written request to the Trustee to
institute proceedings in respect of such Event of Default as Trustee and offered
the Trustee reasonable indemnity and the Trustee shall not have received from
the Holders of a majority in principal amount of Notes of this series at the
time Outstanding a direction inconsistent with such request, and shall have
failed to institute any such proceeding, for 60 days after receipt of such
notice, request and offer of indemnity. The foregoing shall not apply to any
suit instituted by the Holder of this Note for the enforcement of any payment of
principal hereof or any interest on or after the respective due dates expressed
herein.


<PAGE>


     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the

under the Indenture at any time by the Company and the Trustee with the consent
of the Holders of not less than a majority in principal amount of the
Outstanding Notes of each series of Notes then Outstanding affected thereby. The
Indenture also contains provisions permitting the Holders of specified
percentages in principal amount of the Notes of each series at the time
Outstanding, on behalf of the Holders of all Notes of such series, to waive
compliance by the Company with certain provisions of the Indenture and certain
past defaults under the Indenture and their consequences. Any such consent or
waiver by the Holder of this Note shall be conclusive and binding upon such
Holder and upon all future Holders of this Note and of any Note issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Note.

the Indenture shall alter or impair (i) the obligation of the Company, which is
absolute and unconditional, to pay the principal of (and Make-Whole Amount, if
any) and interest on this Note at the times, place and rate, and in the coin or
currency, herein prescribed, or (ii) the obligations of the Guarantor, which are
unconditional, in respect of the Guaranteed Obligations.

     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Note is registrable in the Security Register, upon
surrender of this Note for registration of transfer at the office or agency of
the Company in any Place of Payment where the principal of (and Make-Whole
Amount, if any) and interest on this Note are payable, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed by the Holder hereof or his
attorney duly authorized in writing, and thereupon one or more new Notes of this
series, of authorized denominations and for the same aggregate principal amount,
will be issued to the designated transferee or transferees.

     The Notes of this series are issuable only in registered form in
denominations of $1,000 and any integral multiple thereof. As provided in the
Indenture and subject to certain limitations therein set forth, Notes of this
series are exchangeable for a like aggregate principal amount of Notes of this
series of a different authorized denomination, as requested by the Holder
surrendering the same.

     No service charge shall be made for any such registration of transfer or
exchange, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

     Prior to due presentment of this Note for registration of transfer, the
Company, the Guarantor, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Note is registered as the owner hereof
for all purposes, whether or not this Note be overdue, and neither the Company,
the Trustee nor any such agent shall be affected by notice to the contrary.

past, present or future shareholder, officer or director, as

such, of the Company or of any successor, either directly or through the Company
or any successor, under any rule of law, statute or constitutional provision or
by the enforcement of any assessment or by any legal or equitable proceeding or
otherwise, all such liability being expressly waived and released by the
acceptance of this Note by the Holder thereof and as part of the consideration
for the issue of the Notes of this series.

     All capitalized terms used in this Note which are defined in the Indenture
shall have the meanings assigned to them in the Indenture.

Security Identification Procedures, the Company has caused a "CUSIP" number to
be printed on the Notes of this series as a convenience to the Holders of such
Notes. No representation is made as to the correctness or accuracy of such CUSIP
number as printed on the Notes, and reliance may be placed only on the other
identification numbers printed hereon.

     Unless the certificate of authentication hereon has been executed by or on
behalf of the Trustee by manual signature, this Note shall not be entitled to
any benefit under the Indenture or be valid or obligatory for any purpose.

terms, conditions and other provisions of the Partnership Agreement; and

              NOW, THEREFORE, in consideration of the premises and for other
good and valuable consideration, the receipt and sufficiency of which hereby are
acknowledged, the General Partner hereby amends the Partnership Agreement as
follows:

              1. Article I hereby is amended to add the following definition:


<PAGE>


                    "Class D Unit" means a Partnership Unit with such
              designations, preferences, rights, powers and duties as are
              described in Section 4.2.C hereof and that is specifically
              designated by the General Partner as being a Class D Unit.

              2. Section 4.2 hereby is amended by renumbering Section 4.2.D to
be Section 4.2.E and adding after Section 4.2.C the following section:

                    D. Class D Units. Under the authority granted to it by
Section 4.2.A hereof, the General Partner hereby establishes an additional class
of Partnership Units entitled "Class D Units." Class D Units shall have the
designations, preferences, rights, powers and duties as set forth in Exhibit F
hereto.

              3. Section 5.1 hereby is amended by inserting "Subject to the
provisions of Exhibit F hereto," at the beginning of the first sentence.

              4. Exhibit A hereby is amended by replacing such Exhibit A with
the Exhibit A attached to this First Amendment, and the Contributor hereby is
admitted to the Partnership as an Additional Limited Partner.

              5. Exhibit F hereby is added, and shall read as follows:


                                    EXHIBIT F
                                  CLASS D UNITS

              Notwithstanding any other provision of the Partnership Agreement,
including the provisions of Exhibits A through E thereof, Class D Units shall
have the following designations, preferences, rights, powers and duties:

              (1) General. Except as otherwise provided below, each Class D Unit
shall have the same designations, preferences, rights, powers and duties as each
Class A Unit.

              (2) Distributions. Prior to any distribution to Class A Units
pursuant to Section 5.1 of the Agreement, the General Partner shall distribute,
to the extent that there is sufficient Available Cash, to each holder of Class D
Units, a distribution per Class D Unit (multiplied by the Conversion Factor)
equal to the dividend per REIT Share paid by the General Partner for such
quarter multiplied by a fraction, the numerator of which is the number of days
in the quarter or shorter period to which such distribution relates that the
Class D Unit was issued and outstanding, and the denominator of which is the
total number of days in the quarter or shorter period to which such distribution


<PAGE>


relates. To the extent that there is not sufficient Available Cash to pay the
distributions to holders of Class D Units, CarrAmerica Realty GP Holdings, Inc.
and CarrAmerica Realty LP Holdings, Inc. jointly and severally agree (i) to the
extent they have previously received distributions of Available Cash, they will
recontribute such funds, [and (ii) if there remains insufficient Available Cash
after the application of clause (i) above, they will make an additional Capital
Contribution in an amount sufficient to provide sufficient Available Cash to pay
the distribution to all holders of Class D Units].

              (3) Redemption Right. A holder of Class D Units shall not have the
Redemption Right under Section 8.6 of the Agreement with respect to such Class D
Units until on or after the date two (2) years after each Class D Unit is
issued.

              (4) Conversion to Class A Units. If the Partnership consummates
the sale of the Contributed Property (other than in a transaction that would not
trigger gain under Section 704(c) of the Internal Revenue Code of 1986, as
amended), then, on the date that is sixty (60) days following the date of
closing of any such sale, each Class D Unit shall automatically convert to a
Class A Unit, and each Class D Unit shall be canceled and retired.

              6. Any amendments to this First Amendment shall require the
consent of the holders of a majority of the Class D Units.

              7. The Contributor hereby agrees to become a party to the
Partnership Agreement and to be bound by all of the terms, conditions and other
provisions of the Partnership Agreement.

                                     * * * *

                  The Applicable Margin for so long as Carr shall not have
obtained two Investment Grade Ratings (at least one of which shall be from S&P
or Moody's) or after Borrower loses its Investment Grade Rating, shall be as
follows:

                   Applicable

                  Lead Agent shall notify the Banks in writing promptly after it
obtains knowledge of any change in Carr's Investment Grade Rating which shall
effect a change in the Applicable Margin.

of the then most recent valuation date for such Plan, but only to the extent
that such excess represents a potential liability of a member of the ERISA Group
to the PBGC or any other Person under Title IV of ERISA.

otherwise specified herein, all accounting terms used herein shall be
interpreted, all accounting determinations hereunder shall be made, and all
financial statements required to be delivered hereunder shall be prepared in

wishes to amend any covenant in Article V to eliminate the effect of any change
in generally accepted accounting principles on the operation of such covenant
(or if the Lead Agent notifies Carr that the Required Banks wish to amend
Article V for such purpose), then Carr's compliance with such covenant shall be

Borrowing (e.g., a "Euro-Dollar Borrowing" is a Borrowing comprised of
Euro-Dollar Loans) or by reference to the provisions of Article II under which
participation therein is determined (i.e., a "Committed Borrowing" is a
Borrowing under Section 2.1 in which all Banks participate in proportion to

the Fronting Bank on behalf of Carr or CarrAmerica LP pursuant to this Section

Term in amounts such that the aggregate principal amount of Tranche B Loans by
such Bank at any one time outstanding, together with such Bank's pro rata share
of Letter of Credit Usage with respect to Carr LP, shall not exceed the amount
of its Tranche B Commitment. The aggregate amount of Tranche B Loans to be made
hereunder, together with the Letter of Credit Usage with respect to Carr LP,
shall not exceed Seventy-Four Million Dollars ($74,000,000) (the "Tranche B Loan
Amount"). Each Borrowing under this subsection (a) shall be in an aggregate
principal amount of at least $2,500,000, or an integral multiple of $1,000,000


                                       31
<PAGE>

in excess thereof (except that any such Borrowing may be in the aggregate amount
available in accordance with Section 3.2(c)) and shall be made from the several
Banks ratably in proportion to their respective Commitments. Subject to the
limitations set forth herein, any amounts repaid may be reborrowed.
Notwithstanding anything to the contrary, the number of new Borrowings shall be
limited to four Borrowings per month and no more than ten Borrowings shall be

                  SECTION 2.2. Notice of Committed Borrowing. (a) The applicable

(a "Notice of Committed Borrowing") not later than 10:00 a.m. (New York City
time) (x) one Domestic Business Day before each Base Rate Borrowing or (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) 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
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


                                       32
<PAGE>

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


                                       33
<PAGE>

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.  Money Market Borrowings.

                  (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, 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,



                                       34
<PAGE>

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

                  (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


                                       35
<PAGE>

specified in or pursuant to Section 9.1 not later than (x) 10:00 A.M. (New York
City time) on 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,




                                       36
<PAGE>

                  (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,

                  (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


                                       37
<PAGE>

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.


                  (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;



                                       38
<PAGE>

                      (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.

               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


                                       39
<PAGE>

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.



<PAGE>




                  (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


                                       40
<PAGE>

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.

                  (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.

                  (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.

                  "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


                                       43
<PAGE>

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 September 14, 2000 (the "Maturity
Date").

                  SECTION 2.10. Mandatory Prepayment

                  (a) If as of the last day of any calendar quarter the
Borrowers LTV Ratio exceeds the Permitted LTV Ratio, but the Borrowers LTV Ratio
is not greater than 52.5%, and provided that no Event of Default has occurred
and is continuing, either (i) Carr or Carr LP shall add additional Real Property
Assets to the Unencumbered Asset Pool Properties within 90 days of the date the
Borrowers LTV Ratio exceeded the Permitted LTV Ratio, in accordance with the
provisions of Section 3.3, or (ii) the Borrowers and/or CarrAmerica LP shall pay
to the Lead Agent, for the account of the Banks, within 90 days of the date the
Borrowers LTV Ratio exceeded the Permitted LTV Ratio, an amount such that the
Loans outstanding subsequent to such payment do not cause the Borrowers LTV
Ratio to exceed the Permitted LTV Ratio. In the event that the Borrowers LTV
Ratio exceeds the Permitted LTV Ratio and is greater than or equal to 52.5%,
then the Borrowers and/or CarrAmerica LP shall, within twenty-five (25) Domestic
Business Days from the last day of any calendar quarter or the date of any New
Acquisition when the Permitted LTV Ratio is exceeded, pay to the Lead Agent, for
the account of the Banks, an amount such that the Loans outstanding subsequent
to such payment do not cause the Borrowers LTV Ratio to exceed the Permitted LTV
Ratio. Failure by the Borrowers to comply with the Borrowers LTV Ratio within 90
days or 25 Domestic Business Days, as the case may be, of the date of such
non-compliance shall be an Event of Default.

                  (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 the Permitted LTV Ratio 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


                                       46
<PAGE>

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.


                  (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.

                  (d) If as of the last day of any calendar quarter the Carr LTV
Ratio exceeds 50%, but the Carr LTV Ratio is not greater than 52.5%, and
provided that no Event of Default has occurred and is continuing, either (i)
Carr shall add additional Real Property Assets to the Carr Unencumbered Asset
Pool Properties within 90 days of the date the Carr LTV Ratio exceeded 50%, in
accordance with the provisions of Section 3.3, or (ii) Carr shall pay to the
Lead Agent, for the account of the Banks, within 90 days of the date the Carr
LTV Ratio exceeded 50%, an amount such that the Tranche A Loans outstanding
subsequent to such payment shall not cause the Carr LTV Ratio to be greater than
50%. In the event that the Carr LTV Ratio exceeds 50% and is greater than or
equal to 52.5%, then Carr shall, within twenty-five (25) Domestic Business Days
from the last day of any calendar quarter or the date of any New Acquisition
when the Carr LTV Ratio is greater than 50%, pay to the Lead Agent, for the
account of the Banks, an amount such that the Tranche A Loans outstanding
subsequent to such payment shall not cause the Carr LTV Ratio to be greater than


                                       47
<PAGE>

50%. Failure by Carr to comply with the Carr LTV Ratio within 90 days or 25
Domestic Business Days, as the case may be, of the date of such non-compliance
shall be an Event of Default.

                  (e) If as of the last day of any calendar quarter the Carr LP
LTV Ratio exceeds 50%, but the Carr LP LTV Ratio is not greater than 52.5%, and
provided that no Event of Default has occurred and is continuing, either (i)
Carr LP shall add additional Real Property Assets to the Carr LP Unencumbered
Asset Pool Properties within 90 days of the date the Carr LP LTV Ratio exceeded
50%, in accordance with the provisions of Section 3.3, or (ii) Carr LP shall pay
to the Lead Agent, for the account of the Banks, within 90 days of the date the
Carr LP LTV Ratio exceeded 50%, an amount such that the Tranche B Loans
outstanding subsequent to such payment shall not cause the Carr LP LTV Ratio to
be greater than 50%. In the event that the Carr LP LTV Ratio exceeds 50% and is
greater than or equal to 52.5%, then Carr LP shall, within twenty-five (25)
Domestic Business Days from the last day of any calendar quarter or the date of
any New Acquisition when the Carr LP LTV Ratio is greater than 50%, pay to the
Lead Agent, for the account of the Banks, an amount such that the Tranche B
Loans outstanding subsequent to such payment shall not cause the Carr LP LTV
Ratio to be greater than 50%. Failure by Carr LP to comply with the Carr LP LTV
Ratio within 90 days or 25 Domestic Business Days, as the case may be, of the
date of such non-compliance shall be an Event of Default.

                  SECTOPM 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.


                                       48
<PAGE>

                  (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.

                  (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


                                       49
<PAGE>

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.

                  (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


                                       50
<PAGE>

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.

                  (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


                                       51
<PAGE>
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


                                       52
<PAGE>

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

                    (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 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


                                       53
<PAGE>

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.

                  (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


                                       54
<PAGE>

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
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


                                       55
<PAGE>

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
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.

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.

               (d) the existence of any claim, set-off, defense or other right
that either Borrower or CarrAmerica LP may have at any time against any
beneficiary or any transferee of a Letter of Credit (or any Persons for whom any
such beneficiary or any such transferee may be acting), the Lead Agent, the
Fronting Bank or any Bank (other than a defense based on the gross negligence or
wilful misconduct of the Lead Agent, the Fronting Bank or such Bank) or any
other Person, whether in connection with the Loan Documents, the transactions
contemplated hereby or by the Letters of Credit Documents or any unrelated
transaction;

               (e) any draft or any other document presented under or in
connection with any Letter of Credit or other Loan Document proving to be
forged, fraudulent, invalid or insufficient in any respect or any statement
therein being untrue or inaccurate in any respect; provided that payment by the
Fronting Bank under such Letter of Credit against presentation of such draft or
document shall not have constituted gross negligence or wilful misconduct of the
Fronting Bank;

               (f) payment by the Fronting Bank against presentation of a draft
or certificate that does not comply with the terms of the Letter of Credit;
provided that such payment shall not have constituted gross negligence or wilful
misconduct of the Fronting Bank; and

               (g) any other circumstance or happening whatsoever other than the
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 Borrowers or CarrAmerica LP; provided that
such other circumstance or happening shall not have been the result of gross
negligence or wilful misconduct of the Fronting Bank.

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
Carr's articles of incorporation or by-laws or Carr LP's or CarrAmerica LP's
agreement of limited partnership.

                  SECTION 4.6. Financial Information

                  (a) The unaudited consolidated balance sheet of Carr as of
[December 31], 1997, 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 and its consolidated
results of operations for such fiscal year.


                                       64

         (b) Since [December 31], 1997, (i) there has been no material adverse
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
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 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. 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


                                       65
<PAGE>

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. 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, without
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


                                       66
<PAGE>

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.


                  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 G, 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.

                  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.

                  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 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.

                  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


                                       69
<PAGE>

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
bargaining agreements or Multiemployer Plans covering the employees of the

difficulty within the last five (5) years.

                  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 Borrowers. The Borrowers represent that they have delivered to
the Lead Agent true, correct and complete copies of each of the documents set
forth in this Section 4.25. CarrAmerica LP represents that it has delivered to
the Lead Agent and the Banks true, correct and complete copies of all of the

31, 1996, Carr qualified and Carr intends to continue to qualify as a real
estate investment trust under the Code.

                  SECTION 4.18. Ownership of Property. Schedule 4.28 attached
hereto and made a part hereof sets forth all the real property owned or leased
by the Borrowers and Persons in which the Borrowers, directly or indirectly, own
an interest as of the Closing Date. As of the Closing Date, each Borrower and
such Persons have good and insurable fee simple title (or leasehold title if so
designated on Schedule 4.28) to all of such real property, subject to customary


                                       70
<PAGE>

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 Real Property Assets
except as disclosed on Schedule 4.28.

                  SECTION 4.29. Insurance. Each Borrower and CarrAmerica LP
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 Real Property 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 Real
Property 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 Real Property
Assets would maintain.

                  SECTION 4.30. Year 2000 Compliance. Each Borrower and
CarrAmerica LP 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, 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.


                                    ARTICLE V

               (ii) or (iii) above, if the existence of such condition has had
               or is reasonably likely to have a Material Adverse Effect;

                    (l) during any consecutive two year period commencing on or
               after the date hereof, individuals who at the beginning of such
               period constituted the Board of Directors of Carr (together with

               Directors then in the office who either were members of the Board
               of Directors at the beginning of such period or whose election or
               nomination for election was previously so approved) cease for any
               reason to constitute a majority of the members of the Board of
               Directors then in office; or

                    (m) Carr shall cease at any time to qualify as a real estate
               investment trust under the Internal Revenue Code.

                  SECTION 6.2. Rights and Remedies. (a) Upon the occurrence of
any Event of Default described in Sections 6.1(f) or (g), the unpaid principal
amount of, 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 (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
shall thereupon be, 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 other than as provided in the Loan Documents


                                       86
<PAGE>

(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 Borrowers and CarrAmerica LP. Notwithstanding
anything contained in this Agreement to the contrary, (i) Carr and CarrAmerica
LP shall be jointly and severally liable for all Obligations arising hereunder
in connection with the Tranche A Loans, (ii) Carr and Carr LP shall be jointly
and severally liable for all Obligations arising hereunder in connection with
the Tranche B Loans and (iii) Carr LP shall not be liable for any Borrowings
made by Carr or CarrAmerica LP pursuant to the terms hereof.

                  (b) Notwithstanding the foregoing, upon the occurrence and
during the continuance of any Event of Default other than any Event of Default
described in Sections 6.1(f) or (g), the Lead Agent shall not exercise any of
its rights and 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
remedies hereunder in its sole discretion. If the Required Banks shall


                                       87


<PAGE>


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 Borrowers under Section 6.1, the Lead Agent
shall give notice to the Borrowers 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 Borrowers to, and
forthwith upon such demand (but in any event within ten (10) days after such
demand), the Borrowers and/or CarrAmerica LP 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 Borrowers and CarrAmerica LP hereby pledge, assign and
grant 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;

                    (ii) all notes, certificates of deposit and other
               instruments from time to time hereafter delivered to or otherwise


                                       88


<PAGE>


               possessed by the Lead Agent for or on behalf of either Borrower
               or CarrAmerica LP 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 Borrowers and CarrAmerica LP now or hereafter existing
hereunder and under any other Loan Document.

                  (c) The Borrowers and CarrAmerica LP hereby authorize 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 Borrowers and CarrAmerica LP to the Banks in respect of the Letters of
Credit.

                  (d) Neither Borrower, CarrAmerica LP nor any Person claiming
or acting on behalf of or through either Borrower or CarrAmerica LP 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) 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:


                                       89


<PAGE>


                    (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
               otherwise 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 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 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 resonable
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 remaining after payment in full of all of the Obligations of the Borrowers
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.

responsible for or have any duty to ascertain, inquire into or verify (i) any
statement, warranty or representation made in connection with this Agreement or
any borrowing hereunder; (ii) the performance or observance of any of the

liability (except such as result from such indemnitees' gross negligence or
willful misconduct) that such indemnitees may suffer or incur in connection with
this Agreement, the other Loan Documents or any action taken or omitted by such
indemnitees hereunder.

taking or not taking any action under this Agreement.

                  SECTION 7.8. Successor Lead Agent. The Lead Agent may resign

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
State thereof and having a combined capital and surplus of at least

may be removed as Lead Agent hereunder. Upon any such removal of the Lead Agent
in accordance with this Section 7.11, the Required Banks shall have the right to
appoint a successor Lead Agent in accordance with Section 7.8.


                                  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 or Money Market LIBOR 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

                                       93
<PAGE>

         (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. Illagality. 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
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


                                       94

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


                                       95
<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


                                       96
<PAGE>
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


                                       97
<PAGE>

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").

                  (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 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.

         (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


                                       98
<PAGE>

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 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


                                       99
<PAGE>

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

                    (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.


                                   ARTICLE IX

                                  MISCELLANEOUS


                  SECTION 9.1. Notices. All notices, requests and other

or in its Administrative Questionnaire or (z) in the case of any party, such
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
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,


                                      100
<PAGE>

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 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


                                      101
<PAGE>

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, 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

                  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
(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


                                      103
<PAGE>

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) 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 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,


                                      104
<PAGE>

(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
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


                                      105
<PAGE>

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 subscribed 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. 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, 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


                                      106
<PAGE>

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,
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 Co-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 Co-Agents and the Banks may


                                      107
<PAGE>

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


                                      108
<PAGE>

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

                                      109
<PAGE>
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 shall
survive the execution and delivery of this Agreement and the other Loan
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
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 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
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.

                  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 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
information confidential on a similar basis pursuant to professional ethical
obligations) any information with respect to the Borrowers, CarrAmerica LP, any
Subsidiary thereof or any of their assets or properties which is furnished

any report, statement or testimony submitted to any local, state or federal
regulatory body having or claiming to have jurisdiction over such Bank, any
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.

                  Section 9.15. Co-Agents. Bank of America National Trust and
Savings Association (successor by merger to Bank of America Illinois),
Commerzbank Aktiengesellschaft, New York Branch, Nationsbank, N.A. and Wells

hereunder. Each Bank shall, ratably in accordance with its Commitment, indemnify
the Co-Agents, their affiliates and their respective directors, officers, agents
and employees (to the extent not reimbursed by the Borrowers or CarrAmerica LP)
against any cost, expense (including counsel fees and disbursements), claim,
demand, action, loss or liability (except such as result from such indemnitees'
gross negligence or willful misconduct) that such indemnitees may suffer or
incur but solely in connection with any such claim that may result pursuant to
the Co-Agents acting as Co-Agents under this Agreement.

                  Section 9.16. No Bankruptcy Proceedings. Each of the Borrower,

                  7. The Designor unconditionally agrees to pay or reimburse the
Designee and save the Designee harmless against all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind or nature whatsoever which may be imposed or asserted
by any of the parties to the Loan Documents against the Designee (except as set
forth in Section 8 below), in its capacity as such, in any way relating to or
arising out of this Agreement or any other Loan Documents or any action taken or
omitted by the Designee hereunder or thereunder, provided that the Designor
shall not be liable for any portion of such liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
if the same results from the Designee's gross negligence or willful misconduct.

                  8. Upon such acceptance and recording by the Lead Agent, as of
the Effective Date, the Designee shall be a party to the Credit Agreement with a
right (subject to the provisions of Section 2.3(b)) to make Money Market Loans
as a Bank pursuant to Section 2.3 of the Credit Agreement and the rights and
obligations of a Bank related thereto; provided, however, that the Designee
shall not be required to make payments with respect to such obligations except
to the extent of excess cash flow of such Designee which is not otherwise
required to repay obligations of such Designated Lender which are then due and
payable. Notwithstanding the foregoing, the Designor, as administrative agent
for the Designee, shall be and remain obligated to the Borrower, the Co-Agents
and the Banks for each and every of the obligations of the Designee and its
Designor with respect to the Credit Agreement, including, without limitation,
any indemnification obligations under Section 7.6 of the Credit Agreement and
any sums otherwise payable to the Borrower by the Designee.

                  9. This Designation Agreement shall be governed by, and
construed in accordance with, the laws of the State of New York.

                  10. This Designation Agreement may be executed in any number
of counterparts and by different parties hereto in separate counterparts, each
of which when so executed shall be deemed to be an original and all of which
taken together shall constitute one and the same agreement. Delivery of an
executed counterpart of a signature page to this Designation Agreement by
facsimile transmission shall be effective as delivery of a manually executed
counterpart of this Designation Agreement.
