       (LIQUIDATION PREFERENCE EQUIVALENT TO $25.00 PER DEPOSITARY SHARE)
                            ------------------------

    CarrAmerica  Realty  Corporation  (the  'Company') is a publicly traded real
estate investment trust that focuses primarily on the acquisition,  development,
ownership and operation of office  properties in select suburban  markets across
the United States.

    Each of the 6,000,000  Depositary  Shares (the 'Depositary  Shares') offered
hereby  represents  a 1/10  fractional  interest  in a share of  8.55%  Series C
Cumulative  Redeemable  Preferred  Stock,  par value $.01 per share (a 'Series C
Preferred Share'), of the Company deposited with BankBoston,  N.A., as Preferred
Stock  Depositary,  and  entitles  the  holder to all  proportional  rights  and
preferences  of the  Series C  Preferred  Shares  (including  dividend,  voting,
redemption and liquidation rights and preferences).  The liquidation  preference
of each Series C Preferred Share is $250.00 (equivalent to $25.00 per Depositary
Share).  See  'Description  of the  Series C  Preferred  Shares  and  Depositary
Shares.'

    Dividends on the Series C Preferred  Shares  represented  by the  Depositary
Shares will be  cumulative  from the date of original  issue and will be payable
quarterly  in arrears on the last day of February,  May,  August and November of
each  year (or,  if such day is not a  business  day,  the next  business  day),
commencing  on  November  30,  1997,  at the rate of  8.55%  of the  liquidation
preference  per annum  (equal to $2.1375 per  Depositary  Share per annum).  See
'Description of Series C Preferred Shares and Depositary Shares--Dividends.'

    The Series C Preferred Shares  represented by the Depositary  Shares are not
redeemable  prior to  November  6, 2002.  On and after  such date,  the Series C
Preferred Shares represented by the Depositary Shares may be redeemed,  in whole
or in part,  at the option of the  Company,  at a  redemption  price of $250 per
Series C  Preferred  Share  (equal to $25.00  per  Depositary  Share),  plus all
accrued and unpaid dividends.  The Series C Preferred Shares  represented by the
Depositary  Shares  will  not  be  subject  to any  sinking  fund  or  mandatory
redemption and will not be convertible into any other securities of the Company.
See    'Description    of   Series   C   Preferred    Shares   and    Depositary
Shares--Redemption.'  Subject to certain limited  exceptions,  ownership of more
than 5% of the Series C Preferred Shares represented by the Depositary Shares is
restricted  in order to  preserve  the  Company's  status as a REIT for  federal
income tax  purposes.  In addition,  the  Company's  charter  documents  contain
certain  restrictions  on ownership  of capital  stock of the Company by foreign
investors.  See  'Description  of Preferred  Stock--Restrictions  on Ownership,'
'Description   of  Depositary   Shares--General'   and  'Risk   Factors--Special
Considerations for Foreign Investors' in the accompanying Prospectus.

    The Company intends to file an application to list the Depositary Shares on
the New  York  Stock  Exchange,  although  there  can be no  assurance  that the
Depositary Shares will be approved for listing.

                                  THE COMPANY

     The Company is a publicly traded real estate investment trust ('REIT') that
focuses  primarily on the acquisition,  development,  ownership and operation of
office  properties in select  suburban  markets across the United States.  As of
October 30,  1997,  the Company  owned  interests  in 232  operating  properties
containing  approximately 17.9 million square feet of office space located in 15
markets,  16 properties  under  construction  that it intends to own and operate
that will contain  approximately  2.7 million  square feet of office space,  and
land and options to acquire land that will support the  development of up to 4.6
million  square feet of office  space.  The  operating  properties  owned by the
Company as of September 30, 1997 were 96.5% leased as of that date.

     The Company has maintained a strategic  alliance with Security Capital U.S.
Realty,  a  European  real  estate  company   (together  with  its  wholly-owned
subsidiary,  'SC-USREALTY')  since  November  1995.  As of  September  30, 1997,
SC-USREALTY  owned  approximately  42.6% of the outstanding  Common Stock of the
Company (38.2% on a fully diluted basis).

     The Company and its  predecessor,  The Oliver Carr Company  ('OCCO'),  have
been in the real estate business in the Washington,  D.C.  metropolitan area for
more than 35 years.  In late 1995,  the Company  shifted its focus from downtown
Washington,  D.C. to a national business  strategy.  The Company provides a full
range of real estate services  through a staff of over 1,000  employees  located
throughout the United States.

                               BUSINESS STRATEGY

     The  Company's   primary  business   objective  is  to  achieve   long-term
sustainable  cash flow growth 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)
developing a national  operating  system that  satisfies and  capitalizes on the
financial and operational  demands of corporate  office space users. The Company
seeks to  acquire  or  develop  properties  characterized  by highly  functional
physical  environments,  strategic  suburban locations in close proximity to key
transportation arteries,  residential areas and other amenities, and low initial
and long-term costs of occupancy.

                              PORTFOLIO BY MARKET

     The Company's  recent  investments  have provided it with a  geographically

                                            will be redeemable at the option of the Company, in whole or in part,
                                            at a redemption price of $250.00 per Series C Preferred Share (equal
                                            to $25.00 per Depositary Share), plus accrued and unpaid dividends
                                            thereon. The redemption price (other than the portion thereof
                                            consisting of accrued and unpaid dividends) is payable solely out of
                                            proceeds from the sale of other capital stock of the Company.

- ------------------
(1) Net income and funds from  operations  include  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.
(2) Weighted  average shares  outstanding  used in calculating net income (loss)
    per share includes Common Stock and, when dilutive, stock equivalents, stock
    options and units of partnership interest.
(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 Inc., by an affiliate of the Company 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 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.

    plus units of partnership  interest in the CarrAmerica Realty, L.P. and Carr
    Realty, L.P. that the holders thereof have a right to have redeemed for cash
    equal to the value of a share of Common Stock for each unit  redeemed or, at

                                  THE COMPANY

     The  Company  is a  publicly  traded  REIT that  focuses  primarily  on the
acquisition, development, ownership and operation of office properties in select
suburban  markets across the United States.  As of October 30, 1997, the Company
owned  interests  in 232  operating  properties  containing  approximately  17.9
million  square feet of office space located in 15 markets,  sixteen  properties
under  construction  that  it  intends  to own and  operate  that  will  contain
approximately  2.7 million square feet of office space,  and land and options to
acquire land that will support the  development of up to 4.6 million square feet
of office space.  The operating  properties owned by the Company as of September
30, 1997 were 96.5% leased as of that date.

     The Company has  maintained a strategic  alliance  with  SC-USREALTY  since
November 1995. As of September 30, 1997,  SC-USREALTY owned  approximately 42.6%
of the outstanding Common Stock of the Company (38.2% on a fully diluted basis).

     The  Company  and its  predecessor,  OCCO,  have  been in the  real  estate
business in the Washington,  D.C.  metropolitan  area for more than 35 years. In
late 1995,  the Company  shifted its focus from downtown  Washington,  D.C. to a
national  business  strategy.  The Company  provides a full range of real estate
services through a staff of over 1,000 employees  located  throughout the United
States.

     The  Company is a Maryland  corporation  that was formed in July 1992.  The
principal  executive  offices of the Company  are  located at 1700  Pennsylvania
Avenue,  N.W.,  Washington,  D.C.  20006,  and its  telephone  number  is  (202)
624-7500.

BUSINESS STRATEGY

     The  Company's   primary  business   objective  is  to  achieve   long-term
sustainable  cash flow growth 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)
developing a national  operating  system that  satisfies and  capitalizes on the
financial and operational  demands of corporate  office space users. The Company
believes that many growth-oriented  companies are relocating to and expanding in
suburban locations that offer lower operating costs,  greater  convenience and a
higher quality of life than traditional central business districts.  The Company
seeks to provide  suburban  office  space that will meet the  changing  needs of
these corporate users of office space.

     Target  Markets.  The Company has focused its  acquisition  and development
activity in the Pacific,  Mountain,  Central and Southeast regions of the United
States,  regions which generally possess strong growth  characteristics.  Within
these regions,  the Company is targeting specific  submarkets in which operating
costs for  businesses are relatively  low,  long-term  population and job growth
generally  are expected to exceed the  national  average,  large,  well-educated
employment  pools exist,  and 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 the  relationships
established by its experienced  market  officers.  The Company's  target markets
include  the  following:  San  Francisco  Bay  Area;  Sacramento;   metropolitan
Washington, D.C.; suburban Atlanta; suburban Chicago; Southeast Denver; suburban
Dallas;  suburban Seattle;  Orange County/Los Angeles; San Diego; Austin, Texas;
suburban  Salt Lake City;  suburban  Phoenix;  Florida  and  suburban  Portland,
Oregon; .

     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 economic base analysis,  job growth and supply and
demand fundamentals. The Company's goal is to become one of the major owners and
operators of office space in each of its selected target  markets.  By achieving
such critical  mass,  the Company  believes that it will be able to better serve
its customers' needs and realize certain operating efficiencies.

     Acquisitions of Operating  Properties.  The Company has implemented a major
initiative to acquire  operating  properties in order to establish the operating
platform for its national business strategy. Between January 1, 1996 and October
30, 1997, the Company acquired 218 operating properties containing approximately
14.5 million square feet of office space, resulting in a more than 425% increase
in the total square  footage of operating  properties in which the Company has a
majority

                                      S-8
<PAGE>
interest. These properties were acquired for an aggregate purchase price of
approximately $1.7 billion. See 'Recent Developments--Recent Acquisitions and
Development Activity.'

     Development  Program.  The  Company's  development  program is  becoming an
increasingly  important  component  of its  growth  strategy  as a result of the
influx of capital into the office  property  market.  The Company  believes that
long-term   investment  returns  resulting  from  developing  office  properties
generally will exceed those from acquiring  office  properties,  and without the
Company assuming significantly increased investment risks. The Company minimizes
its  development   risk  by  employing   extensively   trained  and  experienced
development  personnel,   by  not  assuming  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 its target markets before commencing inventory development in
a  given  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 will construct  prototypical  office buildings  attractive to a
wide  range of  office  users.  Furthermore,  because  the  Company's  inventory
development  projects will typically be between  125,000 and 150,000 square feet
in size,  these projects  individually  are not significant to the Company.  The
Company  does  not  intend  to  have  concentrations  of  inventory  development
exceeding 250,000 rentable square feet in any of its target markets at any given
time.  Although  the Company has no pre-set  leasing  guidelines  for  inventory
development,  on average, the Company expects that its development  projects, in
the aggregate, at any time will be between 60% and 75% leased or committed.  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 raw land for future opportunities.

     To  implement  its national  development  program,  the Company  acquired a
substantial  economic interest in CarrAmerica  Development & Construction,  Inc.
and its  experienced  development  staff  in May  1996  and has  since  employed
additional  development  professionals  in the  Company's  market  offices where
development is taking place. The Company's  development team currently  consists
of  approximately  40 persons who have an average of over 15 years of experience
in developing office properties across the United States. Since January 1, 1997,
the  Company  has  placed  in  service  two  development  properties  containing
approximately 290,000 rentable square feet. In addition, as of October 30, 1997,
the Company  had 16 office  properties  under  construction  (with an  estimated
development  cost of $372.9 million) that it intends to own and operate.  The 16
properties will contain  approximately  2.7 million  rentable square feet. As of
October  30,  1997,   these   properties  were  60%   pre-leased.   See  'Recent
Developments--Recent Acquisitions and Development Activity.'

     Investments in Land for Future Development.  Owning a sufficient  inventory
of land for future development is critical to the Company's development program;
therefore,  the Company will continue to invest in land for future  development.
The Company's goal is to allocate  approximately  5% of its invested  capital to
investments  in land. In addition to its portfolio of operating  properties  and
projects  currently under  development,  the Company owned or controlled,  as of
October 30, 1997, 238 acres of land for future  development in ten of its target
markets.  The Company  also had, as of October 30,  1997,  entered  into binding
agreements  (subject to certain conditions) and non-binding letters of intent to
acquire an additional  156 acres of land for future  development  in five of its
target  markets.  No  assurance  can be given that any of these  potential  land
acquisitions  will be consummated.  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.

     Asset Optimization.  As a component of the Company's business strategy,  it
may sell assets that are  inconsistent  with its  long-term  strategic or return
objectives or where market  conditions for sale are favorable,  and redeploy the
proceeds into other office properties  (utilizing  tax-deferred  exchanges where
possible).  Consistent with this strategy,  the Company  recently sold the First
State Bank Tower in Austin,  Texas,  its 2% interest in the limited  partnership
that owned 1575 Eye Street, Washington,  D.C. and its 5% interest in the limited
partnership  that owns 1776 Eye Street,  Washington,  D.C.  The Company also may
consider selling additional properties or interests in properties, some of which
may be significant.

     National Operating System.  As part of its business strategy, the Company
is implementing a national operating system to provide nationally coordinated
customer service, marketing and

                                      S-9
<PAGE>
development.   The  Company's   national  operating  system  consists  of  three
components:  (i) a Market  Officer  Group,  currently  consisting  of ten 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 National  Marketing  Group,  which,  is
dedicated to marketing the Company's products and services to a targeted list of
major corporate users of office space; and (iii) a National  Development  Group,
which is responsible for developing  suburban office  properties,  build-to-suit
facilities  and business  parks.  The  Company's  national  operating  system is
designed to satisfy and capitalize on the financial and  operational  demands of
corporate  office space users.  The Company  believes  that through its existing
portfolio of operating properties,  property development  opportunities and land
acquired for future  development,  the Company can generate  incremental  demand
through the relocation and expansion needs of many of its customers, both within
a target market and in multiple target markets.

FINANCING STRATEGY

     In order to meet its capital requirements at a reasonable cost, the Company
will  require  access to diverse  sources of capital,  including  the common and
preferred stock markets, the private market for operating partnership units, and
the public and private debt markets.  In order to ensure access to these capital
sources,   the  Company's  financial  strategy  is  predicated  on  conservative
financial policies.

     Common Stock,  including operating  partnership units that may be exchanged
for shares of Common Stock, is and will continue to be the largest  component of
the Company's capital structure. Since January 1996, the Company has raised more
than  $1.0  billion  from  the  sale  of  shares  of  Common  Stock   (including
SC-USREALTY's  initial $250 million investment in the Company) and $43.5 million
from the issuance of operating partnership units. Of the total Common Stock sold
since SC-USREALTY's initial investment in the Company, SC-USREALTY has purchased
$232 million,  or 30.0%.  The Company  currently  expects that  SC-USREALTY will
continue to  participate  in future Common Stock  offerings,  although it is not
obligated to do so.

     To date,  preferred  stock has been only a small component of the Company's
capital structure. As of October 30, 1997, the Company had approximately 780,000
shares of Series A Cumulative Convertible Redeemable Preferred Stock outstanding
(1,740,000  were  issued  originally)  and  8,000,000  shares of 8.57%  Series B
Cumulative Redeemable Preferred Stock issued and outstanding.  The Company plans
to increase its preferred stock capitalization through this offering and through
future  offerings;  however,  the  Company  currently  does not expect  that its
preferred  stock  capitalization  will  exceed  20% of its total  equity  market
capitalization.

     Debt from the public and private  debt  markets is also a key  component of
the Company's capital structure. In June 1997, the Company sold to institutional
investors  unsecured notes for net proceeds of  approximately  $272 million.  In
formulating its debt capitalization  strategy, the Company considers a number of
factors,   including   the   benefits   of   Company-based   financings   versus
asset-specific   financings,   floating  rate  debt   exposure,   debt  maturity
management,  coverage  ratios and total debt  outstanding  as  compared to asset
values.  Although  the  Company may from time to time  assume  mortgage  debt in
connection with property acquisitions,  the Company, in accordance with its debt
capitalization  strategy, plans to primarily utilize Company-based financings in
the form of long-term,  unsecured,  fixed rate bonds, rather than asset-specific
mortgage  financings.  The maturities of bonds issued will be staggered in order
to produce normalized  maturities and therefore  mitigate  refinancing risk. For
short-term  debt  capitalization,  the  Company  will  continue  to utilize  its
unsecured,  floating  rate,  revolving  line of credit to provide the  necessary
capital for  acquisitions  and  development.  With respect to floating rate debt
exposure,  the Company  plans to keep its average  unhedged  floating  rate debt
outstanding to an amount less than 10% of total asset value. The Company expects
to continue operating with adequate debt service coverage ratios and to continue
maintaining a sufficient  pool of  unencumbered  assets to service the Company's
unsecured debt.

     The  Company's  financing  strategy may be changed from time to time by its
Board  of  Directors   without  the  consent  of  its   stockholders   or  other
securityholders.

REAL ESTATE SERVICES

     The Company  generally  provides  real estate  operating  services  for its
properties.  In certain  circumstances,  however,  such as during a transitional
period  following  the  acquisition  of  a  property,  the  Company  may  use  a
third-party  real estate service  provider.  As of October 30, 1997, the Company
provided its own real estate operating  services for approximately  17.5 million
square  feet  (or  98%)  of  its  portfolio.   The  Company,   through   certain
subsidiaries,  also  provides  fee-based  real estate  services  for related and
unrelated parties.

     As of October 30, 1997, the Company had entered into four binding contracts
(subject to certain  conditions) and one non-binding letter of intent to acquire
an  additional  eleven  operating  office  properties  containing  approximately
1,108,000  rentable square feet for an aggregate purchase price of approximately
$157  million.  The  closing  of these  pending  acquisitions  is subject to the
Company's due diligence and

certain other closing conditions.  The Company expects to close the transactions
within  60  days,  although  there  can  be  no  assurance  that  any  of  these
transactions will be consummated.

     OmniOffices  Acquisition.  On August 25, 1997,  an affiliate of the Company
('OmniOffices')  acquired  substantially all of the assets of OmniOffices,  Inc.
and its  subsidiaries  for an  aggregate  purchase  price of  approximately  $50
million  in  cash.  OmniOffices  is one of the  nation's  leading  providers  of
executive  office suites to commercial  customers  throughout the United States,
operating  28  executive  suites  centers  located in 14  markets.  The  Company
believes that there is significant potential for growth in this business because
the demand for  executive  office  suites is likely to increase as  corporations
seek greater flexibility and alternative  workplace solutions for their staffing
and business plan  requirements.  The Company believes that this acquisition has
provided  OmniOffices  with the  operating  platform  necessary  to  expand  its
business  and assist the Company in meeting the  changing  office space needs of
the Company's  national  customers.  The Company expects that  OmniOffices  will
expand its business through development and acquisitions financed principally by
the Company until such expansion can be financed through  third-party  financing
sources.   Because  of  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.

RECENT FINANCING ACTIVITY

     Since June 1996,  the Company has  completed  four  separate  offerings  of
shares of Common Stock to the public and  SC-USREALTY for aggregate net proceeds
of  approximately  $767  million.  In October  1996,  the Company sold shares of
preferred stock to  institutional  investors and SC-USREALTY for net proceeds of
approximately  $43 million.  In June 1997, the Company sold  unsecured  notes to
institutional  investors  for net proceeds of  approximately  $272  million.  In
addition,  in August  1997,  the  Company  sold  shares  of Series B  Cumulative
Redeemable preferred stock to the public for net proceeds of approximately

                                      S-13

$193 million.  The net proceeds of all of these  offerings were used to pay down
indebtedness  and to  acquire  operating  office  properties  and land  held for
development.

     In  September  1997,  certain  modifications  were  made  to the  Company's
unsecured line of credit and, as a result,  the full  commitment  amount of $450
million became available to the Company.  Additionally, on October 30, 1997, the
interest  rate for advances  under the  Company's  unsecured  line of credit was
reduced  to 1.000%  over  LIBOR.  As of  October  30,  1997,  $194  million  was
outstanding under the Company's line of credit.

                                USE OF PROCEEDS

     The net  proceeds to the Company  from this  offering  are  estimated to be
approximately $144.9 million ($166.7 million if the Underwriters' over-allotment
option is exercised in full). The Company intends to use the net proceeds of the
offering to fund acquisition and development  activities,  either through direct
payments or repayment of unsecured  line of credit  borrowings  incurred to fund
acquisition or development  activities,  and for general corporate purposes. The
Company expects to make additional borrowings under its unsecured line of credit
following  the  offering.  Pending  such  application,  the net  proceeds may be
invested in short-term,  income-producing  investments such as commercial paper,
government   securities   or  money  market  funds  that  invest  in  government
securities. See 'Plan of Distribution.'

                                 CAPITALIZATION

     The  following  table sets forth the  capitalization  of the  Company as of
September  30,  1997 on an  historical  basis and on a pro forma  basis,  giving
effect to (i) the  completion  of this  offering  of  Depositary  Shares and the
application of the net proceeds  therefrom,  (ii) the  acquisitions and sales of
office  properties and land that the Company has consummated since September 30,
1997 and expects to  consummate  in the near future,  and (iii) the repayment of

         DESCRIPTION OF SERIES C PREFERRED SHARES AND DEPOSITARY SHARES

     The following  description  of  particular  terms of the Series C Preferred
Shares  and  Depositary  Shares  supplements,  and  to the  extent  inconsistent
therewith, replaces, the description of the general terms of the Preferred Stock
and  Depositary  Shares  set  forth  in the  accompanying  Prospectus,  to which
description  reference is hereby made. The following description is qualified in
its  entirety by  reference  to the  provisions  of the  Articles  Supplementary
relating to the Series C Preferred Shares (the 'Articles Supplementary') and the
Company's Charter, which are incorporated by reference herein.

GENERAL

     Subject to  limitations  prescribed  by Maryland law and its  Charter,  the
Company is authorized to issue,  from its authorized but unissued capital stock,
shares of Preferred  Stock in one or more series,  in such numbers of shares and
with such designations, preferences, conversion and other rights, voting powers,
restrictions,   limitations  as  to  dividends,  qualifications  and  terms  and
conditions of redemption as the Company's  Board of Directors may authorize from
time to time. The Company  currently has outstanding  780,000 shares of Series A
Cumulative  Convertible  Redeemable  Preferred  Stock (the  'Series A  Preferred
Shares'), and 8,000,000 shares of 8.57% Series B Cumulative Redeemable Preferred
Stock (the 'Series B Preferred  Shares').  The Board of Directors has authorized
the Company to designate and issue the Series C Preferred  Shares.  The Series C
Preferred  Shares will rank on a parity  with the Series A Preferred  Shares and
the  Series  B  Preferred  Shares  as to  dividends  and  amounts  payable  upon
liquidation.

     When  issued,  the  Series C  Preferred  Shares and the  Depositary  Shares
representing them will be validly issued,  fully paid and nonassessable.  Unless
redeemed by the Company, the Series C Preferred Shares and the Depositary Shares
will have a  perpetual  term with no stated  maturity  date.  The holders of the
Series C Preferred  Shares will have no  preemptive  rights with  respect to any
shares  of the  capital  stock of the  Company  or any other  securities  of the
Company  convertible  into or carrying  rights or options to  purchase  any such
shares.  The Series C  Preferred  Shares and the  Depositary  Shares will not be
subject to any  sinking  fund or other  obligation  of the  Company to redeem or
retire the Series C Preferred Shares.

     The transfer agent,  registrar and dividend disbursing agent for the Series
C Preferred  Shares and the Depositary  Shares will be BankBoston,  N.A.,  which
will  also  serve  as  preferred  stock   depositary   (the   'Preferred   Stock
Depositary').

     Each Depositary Share  represents a 1/10 fractional  interest in a Series C
Preferred  Share.  The Series C  Preferred  Shares  will be  deposited  with the
Preferred Stock Depositary under a Deposit  Agreement (the 'Deposit  Agreement')
among the Company,  the Preferred Stock  Depositary and the holders from time to
time of depositary receipts (the 'Depositary  Receipts') issued by the Preferred
Stock  Depositary   thereunder.   The  Depositary  Receipts  will  evidence  the
Depositary Shares. Subject to the terms of the Deposit Agreement,  the holder of
each Depositary  Receipt  evidencing a Depositary  Share will be entitled to all
rights and  preferences  of a 1/10  fractional  interest in a Series C Preferred
Share  (including  dividend,  voting,  redemption  and  liquidation  rights  and
preferences).  See  'Description  of  Depositary  Shares'  in  the  accompanying
Prospectus.

     The Company intends to file an application to list the Depositary Shares on
the New York Stock  Exchange.  If the  application  is approved,  trading of the
Depositary  Shares on the Exchange is expected to commence  within 30 days after
the date of this Prospectus  Supplement.  Although the Underwriters have advised
the Company that they intend to make a market in the  Depositary  Shares  before
the  commencement of trading on the New York Stock  Exchange,  they are under no
obligation  to do so,  and no  assurance  can be  given  that a  market  for the
Depositary  Shares will exist before any commencement of trading on the New York
Stock Exchange. See 'Underwriting.' The Company does not expect that any trading
of the Series C Preferred Shares except as represented by the Depositary  Shares
will develop. The Company does not intend to apply for a listing of the Series C
Preferred  Shares on any exchange or to have them authorized for trading through
any inter-dealer quotation system.

RANKING

     With  respect  to  payment  of  dividends  and  amounts  upon  liquidation,
dissolution or winding up, the Series C Preferred  Shares will rank equally with
the  Company's  outstanding  Series A  Preferred  Shares and Series B  Preferred
Shares, junior to all debt securities and senior to the Common Stock.

     While any Series C Preferred  Shares are  outstanding,  the Company may not
authorize,  create or increase  the  authorized  amount of any class of security
that ranks  senior to the Series C Preferred  Shares with respect to the payment
of dividends or amounts payable upon liquidation,  dissolution or winding up, or
any class of  security  convertible  into  shares of such a class,  without  the
consent of the  holders of  two-thirds  of the  outstanding  Series C  Preferred
Shares and Parity Shares (as defined below),  voting as a single class. However,
the  Company  may  create  additional  classes  of  other  stock,  increase  the
authorized  number of  preferred  shares or issue  series  of  preferred  shares
ranking on a parity with the Series C Preferred  Shares  with  respect,  in each
case,  to the  payment  of  dividends  and  amounts  payable  upon  liquidation,
dissolution  and winding up (a 'Parity Share') without the consent of any holder
of Series C Preferred Shares. See '--Voting Rights' below.

DIVIDENDS

     Holders of Depositary Shares representing Series C Preferred Shares will be
entitled to receive,  when and as  declared  by the Board of  Directors,  out of
funds legally  available for the payment of dividends,  cumulative  preferential
cash  dividends  at the rate of 8.55% of the  liquidation  preference  per annum
(equivalent to $2.1375 per Depositary  Share per annum).  Such dividends will be
cumulative  from the date of original issue and payable  quarterly in arrears on
the last  calendar day (or, if such day is not a business day, the next business
day) of each  February,  May,  August and November  (each,  a 'Dividend  Payment
Date').  The first  dividend,  which will be paid on or about November 30, 1997,
will be for less than a full  quarter.  Such first  dividend  and any  dividends
payable on the Series C Preferred Shares for any partial dividend period will be
computed  on the basis of the actual  number of days in such  period.  Dividends
will be  payable  to  holders  of record as they  appear in the  records  of the
Company at the close of business on the  applicable  record date,  which will be
the date designated as such by the Board of Directors of the Company that is not
more than 50 nor less than 10 days prior to such Dividend  Payment Date (each, a
'Dividend  Record  Date').  Accrued and unpaid  dividends  for any past dividend
periods may be  declared  and paid at any time and for such  interim  periods to
holders of record on the applicable  Dividend Record Date. Any dividend  payment
made on the  Series C  Preferred  Shares  will  first be  credited  against  the
earliest  accrued but unpaid dividend due with respect to the Series C Preferred
Shares that remains payable.

     Dividends  on Series C  Preferred  Shares  will  accrue  whether or not the
Company has earnings,  whether or not there are funds legally  available for the
payment of such  dividends and whether or not such  dividends  are declared.  No
interest, or sum of money in lieu of interest, will be payable in respect of any
dividend  payment or payments  on the Series C  Preferred  Shares that may be in
arrears.  Holders  of Series C  Preferred  Shares  will not be  entitled  to any
dividends,  whether  payable in cash,  property or shares of stock, in excess of
the full cumulative  dividends,  as described  herein, on the Series C Preferred
Shares.

     If, for any taxable year,  the Company elects to designate as 'capital gain
dividends'  (as defined in Section 857 of the Internal  Revenue Code of 1986, as
amended, or any successor revenue code or section (the 'Code')) any portion (the
'Capital Gains  Amount') of the dividends  (within the meaning of the Code) paid
or made  available  for the year to holders of all classes of capital stock (the
'Total  Dividends'),  then the portion of the Capital  Gains Amount that will be
allocable  to holders of Series C Preferred  Shares will be in the same  portion
that the Total  Dividends  paid or made  available  to the  holders  of Series C
Preferred Shares for the year bears to the Total Dividends.

     Except as provided in the next  sentence,  no dividends will be declared or
paid on any Parity Shares unless full  cumulative  dividends  have been declared
and paid or are contemporaneously  declared and funds sufficient for the payment
thereof  set aside for such  payment  on the Series C  Preferred  Shares for all
prior dividend  periods.  If accrued  dividends on the Series C Preferred Shares
for all prior dividend

                                      S-17
<PAGE>
periods have not been paid in full,  then any dividend  declared on the Series C
Preferred  Shares  and on any  Parity  Shares for any  dividend  period  will be
declared  ratably in proportion to accrued and unpaid  dividends on the Series C
Preferred Shares and such Parity Shares.

     The Company will not (i) declare, pay or set apart funds for the payment of
any dividend or other distribution with respect to any Junior Shares (as defined
below) or (ii)  redeem,  purchase or  otherwise  acquire for  consideration  any
Junior  Shares  through a sinking fund or otherwise  (other than a redemption or
purchase or other  acquisition of Common Stock made for purposes of any employee
incentive  or benefit  plan of the  Company or any  subsidiary),  unless (A) all
cumulative  dividends  with  respect  to the Series C  Preferred  Shares and any
Parity Shares at the time such  dividends are payable have been paid or declared
and funds have been set apart for payment of such  dividends and (B)  sufficient
funds have been paid or declared  and set apart for the payment of the  dividend
for the current  dividend  period with respect to the Series C Preferred  Shares
and any Parity Shares.

     As used herein, (i) the term 'dividend' does not include dividends or other
distributions payable solely in Fully Junior Shares, or in options,  warrants or
rights to  subscribe  for or purchase  any Fully  Junior  Shares,  (ii) the term
'Junior  Shares'  means the Common Stock and any other class or series of shares
of capital  stock of the Company now or hereafter  issued and  outstanding  that
ranks junior to the Series C Preferred  Shares as to the payment of dividends or
in the  distribution  of assets or amounts  upon  liquidation,  dissolution  and
winding up and (iii) the term 'Fully  Junior  Shares'  means Junior  Shares that
rank junior to the Series C Preferred Shares both as to the payment of dividends
and distribution of assets upon liquidation, dissolution and winding up.

LIQUIDATION RIGHTS

     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the  Company,  the  holders of Series C  Preferred  Shares  will be  entitled to
receive out of assets of the  Company  legally  available  for  distribution  to
stockholders  a liquidation  preference of $250.00 per Series C Preferred  Share
(equivalent  to  $25.00  per  Depositary  Share),  plus an amount  per  Series C
Preferred  Share  equal to all  dividends  (whether  or not earned or  declared)
accrued and unpaid  thereon to the date of final  distribution  to such holders,
and no more.

     Until the holders of Series C Preferred  Shares and Parity Shares have been
paid their liquidation preference in full, no payment will be made to any holder
of Junior Shares upon the liquidation, dissolution or winding up of the Company.
If upon any liquidation, dissolution or winding up of the Company, the assets of
the Company, or proceeds thereof,  distributable among the holders of the Series
C  Preferred  Shares are  insufficient  to pay in full the amount  payable  upon
liquidation  with respect to the Series C Preferred  Shares and any other Parity
Shares, then such assets, or the proceeds thereof, will be distributed among the
holders of Series C  Preferred  Shares  and any such  Parity  Shares  ratably in
accordance  with the respective  amounts which would be payable on such Series C
Preferred  Shares and any such Parity Shares if all amounts payable thereon were
paid in full.  Neither a  consolidation  or merger of the Company  with  another
entity,  a statutory share exchange by the Company nor a sale, lease or transfer
of all or  substantially  all of the  Company's  assets  will  be  considered  a
liquidation,  dissolution  or  winding  up,  voluntary  or  involuntary,  of the
Company.

REDEMPTION

     The Series C Preferred Shares  represented by the Depositary Shares are not
redeemable by the Company  prior to November 6, 2002.  On and after  November 6,
2002, the Company,  at its option,  may redeem the Series C Preferred Shares, in
whole or in part,  at any time or from  time to time,  for cash at a  redemption
price of $250.00 per share  (equivalent  to $25.00 per Depositary  Share),  plus
accumulated,  accrued  and  unpaid  dividends  thereon  to the  date  fixed  for
redemption,  without  interest.  The redemption  price of the Series C Preferred
Shares  (other  than the  portion  thereof  consisting  of  accrued  and  unpaid
dividends)  is payable  solely out of  proceeds  from the sale of other  capital
stock  of  the  Company,  which  may  include  Common  Stock,  preferred  stock,
depositary shares, interests, participations or other ownership interests in the
Company however designated (other than debt securities convertible into or

                                      S-18
<PAGE>
exchangeable for capital stock), and any rights, warrants or options to purchase
any thereof.  If fewer than all of the outstanding  Depositary  Shares are to be
redeemed,  the number of shares to be redeemed will be determined by the Company
pro rata (as nearly as possible without creating fractional  Depositary Shares),
by lot or by any other method  determined by the Company in its sole  discretion
to be equitable.

     Unless full cumulative  dividends on all Series C Preferred  Shares and any
Parity Shares have been or  contemporaneously  are declared and paid or declared
and a sum sufficient for the payment  thereof set apart for payment for all past
dividend  periods and the then current  dividend  period,  no Series C Preferred
Shares or Parity  Shares may be redeemed  or  purchased  by the  Company  except
pursuant to a purchase  or  exchange  offer made on the same terms to holders of
all outstanding Series C Preferred Shares or Parity Shares, as the case may be.

     Notice  of  a  redemption  of  the  Depositary  Shares  will  be  given  by
publication in a newspaper of general circulation in the City of New York once a
week for two successive  weeks not less than 30 nor more than 90 days before the
redemption date. Another notice of the redemption will be mailed at least 30 but
not more than 90 days  before the  redemption  date to the  holders of record of
Depositary Shares whose Depositary Shares are to be redeemed at their respective
addresses  shown on the stock transfer  books of the Company.  Each notice shall
state:  (i) the  redemption  date;  (ii) the number of  Depositary  Shares to be
redeemed;  (iii) the redemption  price per Depositary  Share;  (iv) the place or
places  where the  Depositary  Shares are to be  surrendered  for payment of the
redemption price; and (v) that dividends on the Depositary Shares to be redeemed
will cease to accrue on such  redemption  date. If fewer than all the Depositary
Shares are to be redeemed,  the notice  mailed to each such holder  thereof will
also specify the number of Depositary Shares to be redeemed from such holder. If
notice of  redemption of any  Depositary  Shares has been given and if the funds
necessary  for such  redemption  have been set aside by the Company in trust for
the benefit of the holders of the  Depositary  Shares so called for  redemption,
then from and after the redemption date,  dividends will cease to accrue on such
Depositary  Shares,  and such  Depositary  Shares  shall  no  longer  be  deemed
outstanding and all rights of their holders will terminate,  except the right to
receive the redemption price.

     The  holders of  Depositary  Shares at the close of  business on a Dividend
Record Date will be entitled to receive the  dividends  payable  with respect to
such   Depositary   Shares   on  the   corresponding   Dividend   Payment   Date
notwithstanding the redemption thereof between such Dividend Record Date and the
corresponding  Dividend Payment Date or the Company's  default in the payment of
the dividend due. Except as provided above,  the Company will make no payment or
allowance for unpaid dividends,  whether or not in arrears, on Depositary Shares
which have been called for redemption.

     The Series C Preferred  Shares  represented  by  Depositary  Shares have no
stated  maturity  and will  not be  subject  to any  sinking  fund or  mandatory
redemption provisions.

VOTING RIGHTS

     Except  as  indicated  below,  or  except  as  otherwise  from time to time
required by applicable law, the holders of Series C Preferred Shares represented
by Depositary Shares will have no voting rights.

     On any matter on which the Series C Preferred  Shares are  entitled to vote
(as expressly  provided in the Articles  Supplementary  or as may be required by
law),  including any action by written  consent,  each Series C Preferred  Share
will be  entitled to one vote,  except  that when shares of any other  series of
Preferred  Stock have the right to vote with the Series C Preferred  Shares as a
single class on any matter,  the Series C Preferred Shares and the shares of the
other  series will have one vote for each $25.00  liquidation  preference.  As a
result,  each Depositary  Share will be entitled to one vote on such matters and
1/10 of a vote on other matters.

     If dividends  payable on the Series C Preferred Shares or any Parity Shares
are in  arrears  for six or more  quarterly  periods,  whether  or not earned or
declared and whether or not such quarterly  periods are consecutive,  the number
of  directors  then  constituting  the Board of Directors of the Company will be
increased  by two, and the holders of the  Depositary  Shares  representing  the
Series C Preferred Shares,

                                      S-19
<PAGE>
voting  together  as a class  with the  holders  of any  other  series of Parity
Shares,  will have the right to elect two  additional  directors to serve on the
Company's  Board of  Directors  at any annual  meeting of  stockholders  or at a
properly called special meeting of the holders of the voting Parity Shares until
all such dividends and dividends for the current  quarterly period on the Series
C Preferred  Shares and such other voting  Parity  Shares have been declared and
paid or set aside for payment.  Such voting rights will  terminate when all such
accrued  and  unpaid  dividends  have  been  declared  and paid or set aside for
payment.  The term of office of all directors so elected will terminate with the
termination of such voting rights.

     The  approval  of  two-thirds   of  the   outstanding   Depositary   Shares
representing  Series C Preferred  Shares and all other Parity  Shares  similarly
affected,  voting  as a single  class,  is  required  in order to (i)  amend the
Company's Charter to affect materially and adversely the rights,  preferences or
voting  power of the  holders  of the  Series C  Preferred  Shares or the Parity
Shares;  (ii) enter into a share  exchange  that  affects the Series C Preferred
Shares,  or  consolidate  the  Company  with or merge the Company  with  another
entity,  unless  in each  such  case  each  Series  C  Preferred  Share  remains
outstanding  without a  material  adverse  change to its terms and  rights or is
converted into or exchanged for preferred  stock of the surviving  entity having
preferences,   conversion  and  other  rights,   voting  powers,   restrictions,
limitations  as  to  dividends,  qualifications  and  terms  and  conditions  of
redemption  thereof  identical to that of the Series C Preferred  Shares (except
for changes that do not materially and adversely  affect the holders of Series C
Preferred  Shares),  or (iii)  authorize,  reclassify,  create or  increase  the
authorized  amount of any shares of any class, or any security  convertible into
shares of any class,  having rights senior to the Series C Preferred Shares with
respect to the payment of dividends or amounts upon liquidation,  dissolution or
winding up of the Company. However, the Company may create additional classes of
Parity Shares and Junior Shares, increase the authorized number of Parity Shares
and Junior Shares and issue additional series of Parity Shares and Junior Shares
without the consent of any holder of  Depositary  Shares  representing  Series C
Preferred Shares.

     Except as provided above and as required by applicable  law, the holders of
Depositary  Shares  representing  Series C Preferred  Shares are not entitled to
vote on any merger or consolidation involving the Company, on any share exchange
or on a sale of all or substantially all of the assets of the Company.

CONVERSION

     The Series C Preferred  Shares  represented  by  Depositary  Shares are not
convertible  into or  exchangeable  for any other  property or securities of the
Company at the option of the holder.

RESTRICTIONS ON TRANSFER; OWNERSHIP LIMITS

     For the  Company to  qualify as a REIT under the Code,  no more than 50% in
value of its outstanding stock may be owned, directly or indirectly,  by five or
fewer  'individuals'  during  the last half of a full  taxable  year or during a
proportionate  part of a shorter taxable year. Under the constructive  ownership
provisions of the Code, stock owned by an entity, including a corporation,  life
insurance  company,  mutual  fund or pension  trust,  is treated as owned by the
ultimate individual beneficial owners of the entity. Because the Company intends
to maintain its  qualification as a REIT, the Company's Charter contains certain
restrictions  on the  ownership  and transfer of capital  stock,  including  the
Series C Preferred Shares represented by Depositary  Shares,  intended to assist
the Company in complying with these requirements.  For a complete description of
these  restrictions,   see  'Common  Stock--Restrictions  on  Transfer'  in  the
accompanying Prospectus.

     Subject to certain exceptions specified in the Company's Charter, no holder
may own, or be deemed to own by virtue of certain attribution  provisions of the
Code,  more  than 5% of any class or series  of  Preferred  Stock.  The Board of
Directors  of the  Company  has  waived  this  restriction  with  respect to the
acquisition of Series C Preferred Shares for a holder who is not an 'individual'
within the meaning of Section  542(a)(2) of the Code,  so long as,  through such
holder's  ownership of such Series C Preferred Shares, no 'individual'  would be
considered the beneficial owner of more than 5% of the

                                      S-20
<PAGE>
Series C  Preferred  Shares.  If a holder  were to  acquire  more than 5% of the
Series C Preferred Shares and such holder did not meet the criteria set forth in
the preceding sentence,  such holder's shares of Series C Preferred Shares would
be subject to the  provisions  in the Charter  relating  to a  violation  of the
ownership limits as described in the  accompanying  Prospectus under the caption
'Description of Common  Stock--Restrictions  on Transfer--Violation of Ownership
Limits.'

     In order to assist the Company in qualifying as a 'domestically controlled
REIT,' the Company's Charter contains certain provisions generally preventing
foreign investors (other than SC-USREALTY and its affiliates) from acquiring
additional shares of the Company's capital stock if, as a result of such
acquisition, the Company would fail to qualify as a 'domestically controlled
REIT.' Accordingly, an acquisition of the Company's capital stock (including the
Series C Preferred Shares) would not likely be a suitable investment for
non-U.S. shareholders other than SC-USREALTY. See 'Risk Factors-- Special
Considerations for Foreign Investors.'

BOOK-ENTRY ONLY SYSTEM

     The  Depositary  Shares will be issued in  book-entry  form,  meaning  that
beneficial owners of the Depositary Shares will not receive physical delivery of
depositary receipts or certificates  evidencing their ownership interests in the
Depositary  Shares except in the event the book-entry  system for the Depositary
Shares is discontinued. The Depository Trust Company ('DTC'), New York, New York
will act as securities  depository  for the  Depositary  Shares.  The Depositary
Shares will be issued as fully-registered  securities  registered in the name of
Cede & Co., as DTC's nominee.  One  fully-registered  depositary receipt will be
issued for the Depositary  Shares,  in the aggregate number of Depositary Shares
issued, and will be deposited with DTC.

     DTC is a limited purpose trust company organized under the New York Banking
Law, a member of the Federal Reserve System, a 'clearing corporation' within the
meaning  of the  New  York  Uniform  Commercial  Code  and a  'clearing  agency'
registered  pursuant to the provisions of Section 17A of the Securities Exchange
Act  of  1934,  as  amended.   DTC  holds   securities  that  its   participants
('Participants')  deposit with it. DTC also  facilitates  the  settlement  among
Participants  of  securities  transactions,  such as transfers  and pledges,  in
deposited  securities  through  electronic  computerized  book-entry  changes in
Participants'  accounts,  thereby  eliminating the need for physical movement of
securities  certificates.  Direct  Participants  include  securities brokers and
dealers,  banks,  trust  companies,  clearing  corporations  and  certain  other
organizations.  DTC is owned by a number of its Direct  Participants  and by the
New York Stock  Exchange,  Inc.,  the American  Stock  Exchange,  Inc.,  and the
National  Association of Securities  Dealers,  Inc.  Access to the DTC system is
also  available to others such as  securities  brokers and dealers,  banks,  and
trust companies that clear through or maintain a custodial  relationship  with a
Direct Participant, either directly or indirectly ('Indirect Participants'). The
Rules applicable to DTC and its Participants are on file with the Securities and
Exchange Commission.

     Purchases  of  Depositary  Shares  under the DTC system  must be made by or
through  Direct  Participants,  which will  receive a credit for the  Depositary
Shares on DTC's records. The ownership interest of each actual purchaser of each
Depositary  Share  (a  'Beneficial  Owner')  is in  turn to be  recorded  on the
Participants'  and Indirect  Participants'  records.  Beneficial Owners will not
receive written  confirmation from DTC of their purchase,  but Beneficial Owners
are  expected  to  receive  written  confirmations   providing  details  of  the
transaction,  as well  as  periodic  statements  of  their  holdings,  from  the
Participant or Indirect  Participant  through which the Beneficial Owner entered
into the transaction.  Transfers of ownership interests in the Depositary Shares
are to be accomplished  by entries made on the books of  Participants  acting on
behalf of Beneficial Owners.

     The deposit of  Depositary  Shares with DTC and their  registration  in the
name  of  Cede & Co.  effect  no  change  in  beneficial  ownership.  DTC has no
knowledge  of the  actual  Beneficial  Owners of the  Depositary  Shares;  DTC's
records  reflect only the identity of the  Participants  to whose  accounts such
Depositary Shares are credited,  which may or may not be the Beneficial  Owners.
The Participants  will remain  responsible for keeping account of their holdings
on behalf of their customers.

                                      S-21
<PAGE>
     Conveyance   of  notices  and  other   communications   by  DTC  to  Direct
Participants,  by Direct  Participants  to Indirect  Participants  and by Direct
Participants and Indirect  Participants to Beneficial Owners will be governed by
arrangements  among them,  subject to any statutory or  regulatory  requirements
that may be in effect from time to time.

     Redemption  notices  shall  be  sent  to  DTC.  If  fewer  than  all of the
Depositary  Shares  within an issue are being  redeemed.  DTC's  practice  is to
determine by lot the amount of the interest of each Direct  Participant  in such
issue to be redeemed.

     Neither DTC nor Cede & Co. will consent or vote with respect to  Depositary
Shares.  Under its usual  procedures,  DTC would  mail an  Omnibus  Proxy to the
issuer of  securities  deposited  with it as soon as  possible  after the record
date.  The Omnibus  Proxy  assigns Cede & Co.'s  consenting  or voting rights to
those Direct  Participants  to whose accounts the securities are credited on the
record date (identified in a listing attached to the Omnibus Proxy).

     Dividend and redemption  payments on the Depositary  Shares will be made to
Cede & Co., as nominee of DTC. DTC's practice is to credit Direct  Participants'
accounts upon its receipt of funds and corresponding detail information from the
issuer of the  securities  or its agent on the payable date in  accordance  with
their  respective  holdings shown on DTC's records.  Payments by Participants to
Beneficial  Owners  will be  governed by  standing  instructions  and  customary
practices,  as is the case with securities held for the accounts of customers in
bearer form or registered in 'street  name,' and will be the  responsibility  of
such  Participants and not of DTC, the issuer or the issuer's agent,  subject to
any statutory or regulatory  requirements as may be in effect from time to time.
Remittance  of  dividend  and   redemption   payments  to  Cede  &  Co.  is  the
responsibility  of the issuer or agent,  disbursement of such payments to Direct
Participants  is the  responsibility  of Cede & Co.,  and  disbursement  of such
payments  to the  Beneficial  Owners is the  responsibility  of the  Direct  and
Indirect Participants.

     DTC may  discontinue  providing its services as securities  depository with
respect to the Depositary  Shares at any time by giving reasonable notice to the
Company.  Under such  circumstances,  in the event that a  successor  securities
depository is not obtained,  depositary  receipts  representing  the  Depositary
Shares are required to be printed and delivered.

     The  Company  may decide to  discontinue  use of the  system of  book-entry
transfers  through DTC (or a successor  securities  depository).  In that event,
depositary  receipts  representing  the  Depositary  Shares  will be printed and
delivered.

     The information in this section  concerning DTC and DTC's book-entry system
has been obtained from sources that the Company believes to be reliable, but the
Company does not take responsibility for the accuracy thereof.

                       FEDERAL INCOME TAX CONSIDERATIONS

     The  following is a summary of certain  federal  income tax  considerations
pertaining to the acquisition,  ownership and disposition of Depositary  Shares.
This  discussion  is general in nature and not  exhaustive  of all  possible tax
considerations,  nor does the discussion address any state, local or foreign tax
considerations.  The  discussion is based on current law and does not purport to
deal with all  aspects of federal  income  taxation  that may be  relevant  to a
prospective  shareholder in light of its particular  circumstance  or to certain
types of shareholders  (including insurance companies,  financial  institutions,
broker-dealers,  tax exempt investors,  foreign corporations and persons who are
not  citizens or residents of the United  States)  subject to special  treatment
under the federal  income tax laws.  The Company has not  requested and will not
request a ruling from the Internal  Revenue Service (the 'Service') with respect
to any of the  federal  income  tax  issues  discussed  below.  This  Prospectus
Supplement  does not  address  the  taxation of the Company or the impact on the
Company of its election to be taxed as a REIT. Such matters are addressed in the
accompanying    Prospectus    under   the   captions    'Federal    Income   Tax
Considerations--Taxation  of the Company,'  '--Recent  Legislation' and '--Other
Tax Considerations.'  Prospective  investors should consult, and must depend on,
their own tax advisors

                                      S-22
<PAGE>
regarding  the federal,  state,  local,  foreign and other tax  consequences  of
holding and disposing of Depositary Shares.

TAXATION OF HOLDERS OF DEPOSITARY SHARES

     General. Owners of Depositary Shares will be treated for federal income tax
purposes as if they were owners of the Series C Preferred Shares  represented by
such Depositary Shares.  Accordingly,  such owners will be entitled to take into
account,  for federal  income tax purposes,  income and deductions to which they
would be entitled if they were direct holders of Series C Preferred  Shares.  In
addition, (i) no gain or loss will be recognized for federal income tax purposes
upon the  withdrawal of  certificates  evidencing  Series C Preferred  Shares in
exchange for depositary  receipts,  (ii) the tax basis of each share of Series C
Preferred  Shares to an exchanging  owner of Depositary  Shares will,  upon such
exchange,  be the  same as the  aggregate  tax  basis of the  Depositary  Shares
exchanged  therefor,  and (iii) the holding period for Series C Preferred Shares
in the hands of an exchanging owner of Depositary Shares will include the period
during which such person owned such Depositary  Shares.  For a discussion of the
withdrawal  of  Series  C  Preferred  Shares  generally,   see  'Description  of
Depositary Shares--Withdrawal of Stock' in the accompanying Prospectus.

     Dividends and Other Distributions;  Backup Withholding. For a discussion of
the taxation of the Company,  the treatment of dividends and other distributions
with respect to shares of the Company, and the backup withholding rules, see the
captions  'Federal  Income  Tax  Considerations--Taxation  of the  Company'  and
'--Taxation  of  Holders of Common  Stock' in the  accompanying  Prospectus.  In
determining  the  extent  to  which  a  distribution  on the  Depositary  Shares
constitutes a dividend for tax purposes, the earnings and profits of the Company
will be allocated,  on a pro rata basis,  first to distributions with respect to
the Series A, Series B and Series C Preferred  Shares  represented by Depositary
Shares and then to the Common  Stock.  In the event that the Company  designates
any portion of a dividend as a 'capital gain dividend,' a holder's share of such
capital gain dividend would be an amount which bears the same ratio to the total
amount of  dividends  paid to such holder for the year as the  aggregate  amount
designated  as a capital  gain  dividend  bears to the  aggregate  amount of all
dividends paid on all classes of shares for the year.

     Sale or  Exchange  of  Depositary  Shares.  Upon  the sale or  exchange  of
Depositary  Shares to a party  other than the  Company,  a holder of  Depositary
Shares will realize a capital gain or loss  measured by the  difference  between
the amount realized on the sale or other  disposition and the holder's  adjusted
tax basis in the Depositary Shares (provided the Depositary Shares are held as a
capital  asset).  Under the Taxpayer Relief Act of 1997, net capital gain (i.e.,
generally  capital gain in excess of capital  loss)  recognized by an individual
upon the sale of capital  assets held for more than 18 months  generally will be
subject to tax at a rate not to exceed 20%.  Net capital gain  recognized  by an
individual  from the sale of capital assets held for more than 12 months but for
not more than 18 months  will  continue  to be  subject  to tax at a rate not to
exceed 28%. Capital gain recognized from the sale of a capital asset held for 12
months or less will continue to be subject to tax at ordinary  income rates.  In
addition,  capital gain  recognized by a corporate  taxpayer will continue to be
subject to tax at the oridinary income tax rates applicable to corporations. Any
loss on a sale of Depositary Shares which were held by the holder for six months
or less and with respect to which capital gain  dividends  were received will be
treated as a capital loss attributable to an asset held for more than 12 months,
up to the amount of the capital  gain  dividend  received  with  respect to such
shares.

     Redemption of Depositary Shares.  Whenever the Company redeems any Series C
Preferred  Shares held by the  Depositary,  the Depositary will redeem as of the
same redemption date the number of Depositary  Shares  representing the Series C
Preferred  Stock so redeemed.  The  treatment to a holder of  Depositary  Shares
accorded  to any  redemption  by the  Company  (as  distinguished  from a  sale,
exchange  or  other  disposition)  of  Series  C  Preferred  Shares  held by the
Depositary  and  corresponding  redemption  of  Depositary  Shares  can  only be
determined  on the basis of  particular  facts as to each  holder of  Depositary
Shares at the time of redemption. In general, a holder of Depositary Shares will
recognize  capital  gain  measured  by the excess of the amount  received by the
holder  upon  the  redemption  over  such  holder's  adjusted  tax  basis in the
Depositary Shares redeemed (provided the

                                      S-23
<PAGE>
Depositary Shares are held as a capital asset) if such redemption (i) results in
a 'complete termination' of the holder's interest in all classes of stock of the
Company  under  Section  302(b)(3)  of the  Code,  or (ii)  is 'not  essentially
equivalent to a dividend' with respect to the holder under Section  302(b)(1) of
the Code. In applying these tests, there must be taken into account not only any
Depositary  Shares  owned by the holder,  but also such  holder's  ownership  of
Common  Stock,  other  series of stock and any other  options  (including  stock
purchase rights) to acquire any of the foregoing. The holder also must take into
account any such securities (including options) which are considered to be owned
by such  holder  by  reason  of the  constructive  ownership  rules set forth in
Sections 318 and 302(c) of the Code.

     If  a   particular   holder  of   Depositary   Shares  owns   (actually  or
constructively)  no shares of Common  Stock of the  Company or an  insubstantial
percentage of the outstanding shares of Common Stock of the Company,  based upon
current law, it is probable that the redemption of Depositary Shares from such a
Holder would be considered 'not essentially  equivalent to a dividend.' However,
whether a distribution is 'not essentially  equivalent to a dividend' depends on
all of the facts and  circumstances,  and a holder  intending  to rely on any of
these  tests at the time of  redemption  should  consult  its own tax adviser to
determine their application to its particular situation.

     If the  redemption  does not meet any of the tests under Section 302 of the
Code, then the redemption  proceeds  received from the Depositary Shares will be
treated as a distribution  on the Depositary  Shares as described under 'Federal
Income  Tax  Considerations--Taxation  of  Holder's  of  Common  Stock'  in  the
accompanying  Prospectus.  If  the  redemption  is  taxed  as  a  dividend,  the
Depositary  Holder's  adjusted  tax  basis  in the  Depositary  Shares  will  be
transferred  to any other  stockholdings  of the holder in the  Company.  If the
holder owns no other stockholdings in the Company,  under certain circumstances,
such basis may be transferred to a related person, or it may be lost entirely.

SPECIAL CONSIDERATIONS FOR NON-U.S. SHAREHOLDERS

     There are several  special  considerations  for  prospective  purchasers of
Depositary  Shares who would be non-U.S.  shareholders  (persons  other than (i)
citizens or residents of the United States,  (ii) corporations,  partnerships or
other entities  created or organized  under the laws of the United States or any
political  subdivision  thereof, and (iii) estates or trusts the income of which
is subject to United States federal income  taxation  regardless of its source).
See also  'Federal  Income Tax  Considerations--Taxation  of  Holder's of Common
Stock--Taxation   of  Non-U.S.   Shareholders'   and   'Description   of  Common
Stock--Restrictions on Transfer' in the accompanying Prospectus.

     A non-U.S.  shareholder will be subject to tax under the Foreign Investment
in Real Property Tax Act ('FIRPTA') on the gain attributable to a disposition of
Depositary Shares if the Company does not qualify as a 'domestically  controlled
REIT.' The Company will qualify as a 'domestically controlled REIT' with respect
to a sale by a Non-U.S.  Shareholder  only if  throughout  the five year  period
ending on the date of the  sale,  less than  50%,  by  value,  of the  Company's
outstanding stock is owned by non-U.S.  shareholders.  As of September 30, 1997,
SC-USREALTY,  a  Luxembourg  corporation,   owned  approximately  42.6%  of  the
outstanding  Common Stock (38.2% on a fully  diluted  basis).  In the event that
SC-REALTY and other  shareholders  of the Company who are non-U.S.  shareholders
either currently, or at any time in the future,  collectively own 50% or more of
the  Company's  stock,  the  Company  would fail to  qualify as a  'domestically
controlled  REIT.' The Company does not have knowledge that there  currently are
other non-U.S.  shareholders  that, when considered with SC-REALTY,  would cause
the Company to fail the 50% test, but the vast majority of the Company's  shares
are held in 'street name' and thus the Company is unable to advise a prospective
non-U.S.  shareholder  that the  Company in fact  qualifies  as a  'domestically
controlled REIT.'

     Even if the Company were not a 'domestically  controlled  REIT,' a non-U.S.
shareholder that holds Depositary Shares will not be subject to tax under FIRPTA
provided that (i) the Depositary  Shares are  'regularly  traded' (as defined by
the applicable  Treasury  Regulations) on an established  securities market, and
(ii) such non-U.S.  shareholder  owned 5% or less of the value of the Depositary
Shares,  throughout the five-year period ending on the date of sale. The Company
intends to file an application to

                                      S-24
<PAGE>
list the Depositary Shares on the New York Stock Exchange, although there can be
no assurance that the Depositary Shares will be approved for listing.

     If the gain on the disposition of the Depositary  Shares were to be subject
to tax under  FIRPTA,  a non-U.S.  shareholder  would be subject to the same tax
treatment  as  domestic  shareholders  with  respect  to such gain  (subject  to
applicable  alternative minimum tax and a special alternative minimum tax in the
case of  nonresident  alien  individuals),  and the purchaser of the  Depositary
Shares  would be  required  to  withhold  and  remit to the  Service  10% of the
consideration paid for such Depositary Shares.

                                 LEGAL MATTERS

     The validity of the issuance of the Series C Preferred  Shares  represented
by Depositary  Shares offered  pursuant to this  Prospectus  Supplement  will be
passed upon for the Company by Hogan & Hartson L.L.P., Washington,  D.C. Certain
legal matters will be passed upon for the  Underwriters  by Rogers & Wells,  New
York, New York.

</TABLE>

     Under  the  terms  and  conditions  of  the  Underwriting  Agreement,   the
Underwriters are committed to take and pay for all of the Depositary  Shares, if
any are taken.

     The Underwriters propose to offer the Depositary Shares in part directly to
the public at the initial  public  offering price set forth on the cover page of
this Prospectus  Supplement,  and in part to certain  securities dealers at such
price less a concession of $.50 per share. The Underwriters may allow, and

                                      U-1
<PAGE>
such  dealers  may  reallow,  a  concession  not in  excess of $.40 per share to
certain brokers and dealers.  After the Depositary  Shares are released for sale
to the public,  the offering price and other selling terms may from time to time
be varied by the Representatives.

     The Company has granted the Underwriters an option  exercisable for 30 days
after the date of this  Prospectus  Supplement to purchase up to an aggregate of
900,000 additional Depositary Shares solely to cover over-allotments, if any. If
the Underwriters  exercise their  over-allotment  option,  the Underwriters have
severally agreed,  subject to certain conditions,  to purchase approximately the
same percentage  thereof that the number of Depositary Shares to be purchased by
each of them, as shown in the foregoing table, bears to the 6,000,000 Depositary
Shares offered by this Prospectus Supplement.

     Prior to the Offering,  there has been no public market for the  Depositary
Shares. The Company intends to file an application to list the Depositary Shares
on the New York Stock  Exchange,  although  there can be no  assurance  that the
Depositary Shares will be approved for listing.

     In the  ordinary  course of their  respective  businesses,  certain  of the
Underwriters and their affiliates have provided,  and may in the future provide,
commercial  banking,  investment  banking,  fiduciary and other  services to the
Company. In addition, Morgan Guaranty Trust Company of New York, an affiliate of
J.P. Morgan  Securities  Inc., is the agent for the banks and a lender under the
Company's unsecured line of credit with groups of banks. The entire net proceeds
from this offering of the Depositary Shares may be used to repay Morgan Guaranty
Trust Company of New York, as agent, for a portion of the outstanding borrowings
of the Company.  Since the amount to be repaid to Morgan  Guaranty Trust Company
of New York,  as agent,  exceeds  10% of the net  proceeds  from the sale of the
Depositary  Shares,  the offering is being made  pursuant to the  provisions  of
Rules  2710(c)(8) and  2720(c)(3)(C)  of the National  Association of Securities
Dealers, Inc. See 'Use of Proceeds.'

     The  Company  has agreed to  indemnify  the  several  Underwriters  against
certain liabilities, including liabilities under the Securities Act of 1933.

     In connection with the Offering, the Underwriters may purchase and sell the
Depositary   Shares  in  the  open  market.   These   transactions  may  include
over-allotment  and  stabilizing  transactions  and purchases to cover syndicate
short   positions   created  in  connection   with  the  Offering.   Stabilizing
transactions  consist of certain bids or purchases for the purpose of preventing
or  retarding  a decline  in the  market  price of the  Depositary  Shares;  and
syndicate  short  positions  involve the sale by the  Underwriters  of a greater
number of securities than they are required to purchase from the Company in this
offering.  The  Underwriters  also may  impose a penalty  bid,  whereby  selling
concessions  allowed to syndicate members or other  broker-dealers in respect of
the  securities  sold in this offering for their account may be reclaimed by the
syndicate  if  such  Depositary  Shares  are  repurchased  by the  syndicate  in
stabilizing or covering transactions.  These activities may stabilize,  maintain
or otherwise  affect the market  price of the  Depositary  Shares,  which may be
higher than the price that might otherwise prevail in the open market; and these
activities,  if commenced,  may be discontinued at any time. These  transactions
may be effected on the New York Stock Exchange,  in the over-the-counter  market
or otherwise.

                                  THE COMPANY

     The Company is a  publicly-traded  real estate  investment trust (a 'REIT')
that focuses primarily on the acquisition,  development, ownership and operation
of office properties in select suburban markets across the United States.

     The  Company is a Maryland  corporation  that was formed in July 1992.  The
principal  executive  offices of the Company  are  located at 1700  Pennsylvania
Avenue, Washington, D.C. 20006, and its telephone number is (202) 624-7500.

<PAGE>
                                  RISK FACTORS

     Prospective  investors should carefully consider,  among other factors, the
matters described below.

REAL ESTATE INVESTMENT RISKS

     General.  Investments  in real  property are subject to varying  degrees of
risk.  The yields  available  from  equity  investments  in real  estate and the
Company's  ability  to service  debt will  depend in large part on the amount of
income  generated,  expenses incurred and capital  expenditures  required by its
real property  investments.  The Company's income from office  properties may be
adversely  affected  by a number of  factors,  including  the  general  economic
climate and local real estate  conditions,  an over-supply of, or a reduction in
demand for,  office space in the areas where its  properties are located and the
attractiveness of the properties to prospective tenants.  Income from properties
and  real  estate  values  also  are  affected  by such  factors  as the cost of
compliance with  government  regulation,  including  zoning and tax laws and the
potential for liability under applicable laws. Certain significant  expenditures
associated  with each equity  investment  by the Company in a property  (such as
operating  expenses  and  capital  expenditures  costs) may not be reduced  when
circumstances cause a reduction in income from the property.

     Renewal of Leases and  Reletting  of Space.  The  Company is subject to the
risks that upon  expiration of leases for space located at its  properties,  the
space  may not be relet or, if relet,  the  terms of the  renewal  or  reletting
(including  the cost of required  renovations  or concessions to tenants) may be
less favorable than current lease terms. Although the Company has established an
annual budget for renovation and reletting  costs that it believes is reasonable
in light of each  property's  situation,  no  assurance  can be given  that this
budget  will be  sufficient  to cover  these  costs.  If the  Company  is unable
promptly to relet or renew leases for all or  substantially  all of the space at
its  properties,  if the  rental  rates  upon  such  renewal  or  reletting  are
significantly  lower  than  expected,  or if the  Company's  reserves  for these
purposes  prove  inadequate,  then the  Company's  cash  provided  by  operating
activities and ability to make expected  distributions  to  stockholders or debt
service payments may be adversely affected.

     Possible Environmental Liabilities.  Under various federal, state and local
laws,  ordinances  and  regulations,  a current or previous owner or operator of
real  estate may be  required  to  investigate  and clean up  certain  hazardous
substances  released at the property,  and may be held liable to a  governmental
entity or to third parties for property damage and for investigation and cleanup
costs  incurred  by such  parties  in  connection  with  the  contamination.  In
addition,  some  environmental  laws create a lien on the  contaminated  site in
favor of the government  for damages and costs it incurs in connection  with the
contamination.  The  presence  of  contamination  or the  failure  to  remediate
contamination  may  adversely  affect the owner's  ability to sell or lease real
estate or to borrow using the real estate as  collateral.  The owner or operator
of a site may be liable  under  common  law to third  parties  for  damages  and
injuries resulting from environmental contamination emanating from the site. The
Company has not been  notified by any  governmental  authority  of any  material
non-compliance,  liability  or  other  claim  in  connection  with  any  of  its
properties,  and the  Company is not aware of any other  material  environmental
condition with respect to any of its properties.  No assurance,  however, can be
given that no prior owner created any material environmental condition not known
to the Company,  that no material  environmental  condition  with respect to any
property has occurred  during the Company's  ownership  thereof,  or that future
uses  or  conditions  (including,  without  limitation,  changes  in  applicable
environmental   laws  and   regulations)   will  not  result  in  imposition  of
environmental liability against the Company.

REAL ESTATE FINANCING RISKS

     Debt  Financing.  The Company is subject to the risks  associated with debt
financing,  including the risk that the cash provided by the Company's operating
activities  will be  insufficient  to meet  required  payments of principal  and
interest,  the risk of rising interest rates on the Company's floating rate debt
that is not  hedged,  the  risk  that the  Company  will not be able to repay or
refinance existing

                                       3
<PAGE>
indebtedness (which generally will not have been fully amortized at maturity) or
that the  terms of such  refinancing  will not be as  favorable  as the terms of
existing indebtedness.  In the event the Company is unable to secure refinancing
of such indebtedness on acceptable terms, the Company might be forced to dispose
of properties upon  disadvantageous  terms,  which might result in losses to the
Company,  or to obtain  financing at  unfavorable  terms,  either of which might
adversely  affect the cash flow available for  distribution  to  stockholders or
meet debt service  obligations.  In addition,  if a property or  properties  are
mortgaged to secure  payment of  indebtedness  and the Company is unable to meet
required  mortgage  payments,  the  mortgage  securing  the  property  could  be
foreclosed  upon by, or the  property  could be  otherwise  transferred  to, the
mortgagee with a consequent loss of income and asset value to the Company.

     Degree of Leverage.  At September 30, 1997, on a  consolidated  basis,  the
Company's total indebtedness was approximately $903 million and the ratio of its
total indebtedness to total assets (excluding intangibles) was 36.5%. The degree
to which the Company is leveraged  could have important  consequences to holders
of  the  Securities,   including  affecting  the  Company's  ability  to  obtain
additional  financing in the future for working capital,  capital  expenditures,
acquisitions,  development  or other general  corporate  purposes and making the
Company more vulnerable to a downturn in its business or the economy generally.

ACQUISITION AND DEVELOPMENT RISKS

     The Company intends to continue  acquiring and developing office properties
in markets where it believes that such  acquisition or development is consistent
with the  business  strategies  of the Company.  Acquisitions  entail risks that
investments  will fail to  perform  in  accordance  with  expectations  and that
judgments  with  respect  to the  costs of  improvements  to  bring an  acquired
property up to standards  established for the market position  intended for that
property will prove inaccurate,  as well as general  investment risks associated
with any new real estate investment. See '--Real Estate Investment Risks' above.
New office development also is subject to a number of risks, including,  but not
limited to,  construction  delays or cost  overruns  that may  increase  project
costs,  financing  risks as  described  above,  the failure to meet  anticipated
occupancy or rent levels,  failure to receive  required  zoning,  occupancy  and
other  governmental  permits and authorizations and changes in applicable zoning
and land use laws,  which may result in the incurrence of  development  costs in
connection  with  projects  that are not  pursued to  completion.  In  addition,
because  the  Company  must  distribute  95% of its  taxable  income in order to
maintain  its  qualification  as  a  REIT,  the  Company  anticipates  that  new
acquisitions and developments will be financed primarily through periodic equity
and debt  offerings,  lines of credit or other  forms of  secured  or  unsecured
financing.  If permanent debt or equity financing is not available on acceptable
terms, further  acquisitions or development  activities may be curtailed or cash
available for  distribution to stockholders or to meet debt service  obligations
may be adversely affected.

CHANGE IN BUSINESS STRATEGY; RISKS ASSOCIATED WITH THE ACQUISITION OF
SUBSTANTIAL NEW PROPERTIES

     In 1996, the Company  shifted its emphasis from downtown  Washington,  D.C.
properties  toward a more  national  business  strategy,  focusing  primarily on
office  properties in suburban  growth markets  across the United  States.  This
change  represents a significant  shift in the business strategy of the Company.
Although the Board believes that such a shift in strategy was warranted in light
of the  opportunities  available to the Company,  there is no assurance that the
Company's  efforts to implement its national  business strategy will continue to
be  successful.  Consistent  with the  Company's  strategy of  acquiring  office
properties in suburban growth markets,  the Company  significantly  expanded its
portfolio of office properties in 1996 and has continued to do so in 1997. These
properties  have a  relatively  short  operating  history  under  the  Company's
management  and they may have  characteristics  or  deficiencies  unknown to the
Company affecting their valuation or revenue potential.

                                       4
<PAGE>
SUBSTANTIAL OWNERSHIP OF COMMON STOCK

     As of September 30, 1997,  Security  Capital  Holdings S.A., a wholly owned
subsidiary of Security Capital U.S. Realty (collectively  'SC-USREALTY'),  owned
42.6% of the  outstanding  shares of the  Company's  Common  Stock (38.2% of the
Common  Stock  on a  fully-diluted  basis),  and  SC-USREALTY  has the  right to
nominate a  proportionate  number of the  directors  of the Board based upon its
ownership of stock on a fully-diluted  basis,  rounded down to the nearest whole
number  (but  in no  event  more  than  40%  of  the  directors).  As a  result,
SC-USREALTY  is the largest single  stockholder  of the Company,  while no other
stockholder  is permitted  to own more than 5% of the  Company's  Common  Stock,
subject to certain  exceptions  set forth in the  Articles of  Incorporation  or
approved  by  the  Board.   Although  certain  standstill   provisions  preclude
SC-USREALTY  from  increasing its  percentage  interest in the Company above 45%
until at least April 30, 2001 (subject to certain  exceptions)  and the Articles
of   Incorporation   preclude  it  from  increasing  such  percentage   interest
thereafter,  and SC-USREALTY agreed to certain  limitations on its voting rights
with  respect  to its  shares of Common  Stock,  SC-USREALTY  nonetheless  has a
substantial  influence over the affairs of the Company.  This  concentration  of
ownership in one  stockholder  could  potentially  be  disadvantageous  to other
stockholders'  interests.  In addition, so long as SC-USREALTY owns at least 25%
of the  outstanding  Common  Stock  of the  Company  on a fully  diluted  basis,
SC-USREALTY  will be entitled  (except in certain limited  circumstances),  upon
compliance  with  certain  specified  conditions,  to a  participation  right to
purchase or subscribe  for,  either as part of such  issuance or in a concurrent
issuance,  a total number of shares of Common Stock or Preferred  Stock,  as the
case may be, equal to up to 30% (or 35% in certain  circumstances)  of the total
number of shares or of Common Stock or Preferred Stock, as applicable,  proposed
to be issued by the Company.

LIMITATIONS ON CORPORATE ACTIONS

     In  conjunction  with the  transaction  in which  SC-USREALTY  acquired its
initial  interest in the Company (the  'SC-USREALTY  Transaction'),  the Company
agreed to certain limitations on its operations, including restrictions relating
to incurrence of additional indebtedness,  retention of third-party managers for
the Company's properties, investments in properties other than office buildings,
issuances of limited partnership  interests ('CRLP Units') of Carr Realty, L.P.,
a partnership that owns certain of the Company's  properties,  and certain other
matters.  The Company may take actions  relating to these  matters only with the
consent of SC-USREALTY.  In addition, the Company is contractually  obligated to
abide by certain  limitations  on the amount of assets  that it owns  indirectly
through  other  entities  and the  manner  in which  it  conducts  its  business
(including  the types of assets  that it can  acquire  and own and the manner in
which such assets are operated). The Company also is obligated to use reasonable
efforts to effect all  dispositions of assets in transactions  that are tax-free
exchanges and do not generate  'capital gain  dividends' to  stockholders of the
Company. These limitations (which generally were designed to address special use
tax considerations to foreign  corporations  applicable to SC-USREALTY under the
Internal  Revenue  Code)  limit the  flexibility  of the  Company  to  structure
transactions that might otherwise be advantageous to the Company, and may impair
the Company's ability to conduct its business in the future.

CONFLICTS OF INTEREST

     Certain  members of the  Company's  board of  directors  (the  'Board') and
officers  of the  Company  own CRLP Units and,  thus,  may have  interests  that
conflict  with  stockholders  with respect to business  decisions  affecting the
Company and Carr Realty,  L.P. In particular,  a holder of CRLP Units may suffer
different and/or more adverse tax consequences than the Company upon the sale or
refinancing of some of the properties owned by Carr Realty,  L.P. as a result of
unrealized gain attributable to certain properties.  These CRLP Unit holders and
the Company,  therefore, may have different objectives regarding the appropriate
pricing and timing of a sale or refinancing of properties. Although the Company,
as the sole general partner of Carr Realty, L.P., has the exclusive authority to
determine whether and on what terms to sell or refinance an individual property,
these CRLP Unit  holders  might seek to  influence  the  Company  not to sell or
refinance a  property,  even though  such sale might  otherwise  be  financially
advantageous to the Company, or may seek to influence the Company to

                                       5
<PAGE>
refinance  a  property  with a higher  level of debt  than  would be in the best
interests of the Company.  Although the Company believes that the change in 1996
in its  operational  structure  from an 'UPREIT' to a 'DownREIT'  has and should
continue to reduce,  over time,  these potential  conflicts of interest,  assets
will continue to be owned by Carr Realty, L.P.,  diminishing the effects of this
structural modification.

MANAGEMENT, LEASING AND BROKERAGE RISKS

     The  Company  is  subject  to  the  risks   associated  with  the  property
management,  leasing and brokerage businesses. These risks include the risk that
management  contracts or service agreements with third-party owners will be lost
to  competitors,  that a  property  will be sold and the  Company  will lose the
contract,  that  contracts  will not be renewed upon  expiration  or will not be
renewed on terms  consistent  with current  terms and that leasing and brokerage
activity  generally  may decline.  Each of these  developments  could  adversely
affect the ability of the Company to make expected distributions to stockholders
or debt service payments.

LACK OF VOTING CONTROL OF OPERATING SUBSIDIARIES; OTHER SPECIAL CONSIDERATIONS
RELATED TO OMNIOFFICES

     The Company does not have voting control of Carr Real Estate Services, Inc.
('Carr  Services,   Inc.'),   CarrAmerica   Development  &  Construction,   Inc.
('CarrAmerica Development & Construction') or OmniOffices, Inc. ('OmniOffices'),
and may acquire  economic  interests  in similarly  structured  companies in the
future (collectively, the 'Operating Subsidiaries').  Carr Services, Inc., which
conducts primarily fee-based  management and leasing, has capital stock which is
divided into two classes: voting common stock, approximately 92% and 8% of which
is held by The Oliver Carr Company ('OCCO') and Carr Realty, L.P., respectively;
and nonvoting  common stock,  approximately  95% and 5% of which is held by Carr
Realty,  L.P. and OCCO,  respectively.  OCCO, as the holder of 92% of the voting
common stock,  has the ability to elect the board of directors of Carr Services,
Inc. CarrAmerica Development & Construction,  which conducts primarily fee-based
development,  has capital stock which is divided into two classes: voting common
stock,  99% and 1% of which is held by OCCO and the Company,  respectively;  and
nonvoting  common  stock,  96% and 4% of which is held by the  Company and OCCO,
respectively.  OCCO, as the holder of 99% of the voting  common  stock,  has the
ability  to  elect  the  board  of  directors  of   CarrAmerica   Development  &
Construction.  Oliver  T.  Carr,  Jr.,  who  is  Chairman  of  the  Board  and a
significant  stockholder  of the  Company,  beneficially  owns a majority of the
voting stock of OCCO, which controls the election of directors of Carr Services,
Inc. and  CarrAmerica  Development & Construction.  OmniOffices,  which provides
executive  office  suites to  commercial  customers,  has capital  stock that is
divided into two classes:  voting common stock and nonvoting  common stock.  The
voting stock is owned 17% by OCCO, 35% by SC-USREALTY and 48% by an entity owned
by the Company's six current executive  officers.  The nonvoting common stock is
owned  entirely by the Company.  The holders of the voting  common stock control
the ability to elect the directors of OmniOffices.

     Although  neither  the  right  of Carr  Realty,  L.P.  or the  Company,  as
applicable, to receive distributions with respect to its equity interest in each
Operating  Subsidiary  nor  the  terms  of the  promissory  notes  made  by such
Operating  Subsidiary  and  held  by  Carr  Realty,  L.P.  or  the  Company,  as
applicable,  can be changed by the holder of the  majority of the voting  common
stock  of such  Operating  Subsidiary,  the  Company  will  not be able to elect
directors of each of the  Operating  Subsidiaries,  and its ability to influence
the day-to-day  decisions of each Operating  Subsidiary is limited. As a result,
the board of directors and management of each Operating Subsidiary may implement
business  policies or decisions that might not have been  implemented by persons
elected by the Company and that are adverse to the  interests  of the Company or
that lead to  adverse  financial  results,  which  could  adversely  impact  the
Company's  operating  income and funds  from  operations.  Further,  none of the
Operating  Subsidiaries  is a public  company,  and there is no  market  for the
equity securities held by the Company in any Operating Subsidiary. Consequently,
the Company has no ready  ability to  liquidate  its  holdings in any  Operating
Subsidiary.

                                       6
<PAGE>
     In addition, the provisions in the Code prohibit the Company from having an
investment in any of the Operating Subsidiaries that has a value that exceeds 5%
of the overall value of the Company's assets, before debt. This limitation could
adversely  affect the ability of OmniOffices to grow its business without either
jeopardizing the Company's REIT qualification or,  alternatively,  bringing into
OmniOffices additional investors.

     It is  possible  that the  Company  could elect in the future to dispose of
part  or all  of  its  equity  interest  in  OmniOffices,  including  through  a
distribution of the stock of OmniOffices to the Company's stockholders; however,
no such  intention  presently  exists,  and the  Company  is  subject to certain
contractual restrictions with SC-USREALTY that could preclude or restrict such a
distribution  or  other  disposition.  In  addition,  the  income  from  such  a
disposition  would  not  qualify  for  purposes  of the 75%  gross  income  test
applicable to REITs (see  'Federal  Income Tax  Considerations--Taxation  of the
Company--Income Tests'), which could limit the ability of the Company to dispose
of all of its interest in OmniOffices (through a distribution to stockholders or
otherwise)   in  a  single   transaction.   Finally,   because  of   tax-related
considerations  specific to SC-USREALTY and its indirect interest in OmniOffices
through the Company,  OmniOffices has agreed to conduct its business  subject to
certain  constraints,  even  though  these  constraints  may have the  effect of
precluding OmniOffices from undertaking transactions that would have been in the
best interests of its other shareholders, including the Company.

CHANGES IN POLICIES

     The major  policies of the Company,  including its policies with respect to
development,  acquisitions,  financing,  growth, operations, debt capitalization
and  distributions,  are determined by its Board.  The Board may amend or revise
these and other policies from time to time without a vote of the stockholders of
the Company.  A change in these  policies could  adversely  affect the Company's
financial condition, results of operations, funds available for distributions to
stockholders,  debt service or the market price of the  Securities.  The Company
cannot  change its policy of seeking to  maintain  its  qualification  as a REIT
without the approval of the holders of a majority of the Common Stock.

CERTAIN TAX RISKS

     Tax  Liabilities  as a Consequence of the Failure to Qualify as a REIT. The
Company  believes  that it has operated so as to qualify and has  qualified as a
REIT  under  the  Internal  Revenue  Code of  1986,  as  amended  (the  'Code'),
commencing  with its  taxable  year ended  December  31,  1993,  and  intends to
continue to so operate. No assurance, however, can be given that the Company has
so qualified  or will be able to remain so  qualified.  Qualification  as a REIT
involves the  application of highly  technical and complex Code provisions as to
which  there  are only  limited  judicial  and  administrative  interpretations.
Certain  facts and  circumstances  that may be wholly or  partially  beyond  the
Company's control may affect its ability to qualify or to continue to qualify as
a REIT. In addition,  no assurance can be given that new  legislation,  Treasury
Regulations,   administrative   interpretations  or  court  decisions  will  not
significantly change the tax laws with respect to the Company's qualification as
a REIT or the federal income  consequences of such qualification to the Company.
If the Company fails to qualify as a REIT, it will be subject to federal  income
tax (including any applicable  alternative minimum tax) on its taxable income at
regular corporate rates and it will not be entitled to a deduction for dividends
paid to its stockholders.  In addition,  unless entitled to relief under certain
statutory provisions, the Company would be disqualified from treatment as a REIT
for the four taxable  years  following  the year during which  qualification  is
lost. The additional tax incurred in such event would  significantly  reduce the
cash flow available for  distribution to  shareholders  and to meet debt service
obligations. See 'Federal Income Tax Considerations--Taxation of the Company.'

     REIT  Distribution  Requirements  and Potential  Impact of  Borrowings.  To
obtain the favorable tax treatment  associated  with  qualifying as a REIT under
the Code,  the Company  generally  is required  each year to  distribute  to its
shareholders  at least 95% of its real estate  investment  trust taxable income.
See  'Federal  Income  Tax   Considerations--Taxation  of  the  Company  (Annual
Distribution  Requirements).'  In addition,  the Company will be subject to a 4%
nondeductible excise tax on the amount, if any, by

                                       7
<PAGE>
which  certain  distributions  paid by it with respect to any calendar  year are
less than the sum of 85% of its  ordinary  income,  95% of its capital  gain net
income and 100% of its real estate  investment  trust taxable  income from prior
years that is not deemed to have been distributed under the Code. Differences in
timing between the receipt of income,  the payment of expenses and the inclusion
of such income and the deduction of such expenses in arriving at taxable  income
(of the Company or its  subsidiaries),  or the effect of  nondeductible  capital
expenditures,  the  creation  of  reserves  or  required  debt  or  amortization
payments,  could require the Company,  directly or through its subsidiaries,  to
borrow funds on a short-term  basis to meet the distribution  requirements  that
are necessary to achieve the tax benefits  associated with qualifying as a REIT.
In such  instances,  the  Company  might need to borrow  funds in order to avoid
adverse tax consequences even if management believed that then prevailing market
conditions were not generally favorable for such borrowings.

     Other Tax Liabilities. Even if the Company qualifies as a REIT, the Company
and certain of its subsidiaries will be subject to certain federal, state and
local taxes on its income and property. See 'Federal Income Tax
Considerations--Taxation of the Company and Other Tax Considerations.'

SPECIAL CONSIDERATIONS FOR FOREIGN INVESTORS

     In order to assist the Company in qualifying as a 'domestically  controlled
REIT,' the Company's  Articles of  Incorporation,  as amended (the  'Articles of
Incorporation')   contain  certain  provisions   generally   preventing  foreign
investors (other than SC-USREALTY and its affiliates) from acquiring  additional
shares of the Company's capital stock if, as a result of such  acquisition,  the
Company would fail to qualify as a 'domestically  controlled REIT.' See 'Federal
Income Tax  Considerations--Taxation  of Holders  of Common  Stock--Taxation  of
Non-U.S.  Shareholders.'  Accordingly,  an acquisition of the Company's  capital
stock would not likely be a suitable investment for non-U.S.  shareholders other
than SC-USREALTY. See 'Description of Common Stock--Restrictions on Transfer.'

PRICE FLUCTUATIONS OF THE COMMON STOCK AND TRADING VOLUME;
SHARES AVAILABLE FOR FUTURE SALE

     A number of factors  may  adversely  influence  the price of the  Company's
Common Stock in the public markets,  many of which are beyond the control of the
Company.  These factors  include  possible  increases in market  interest rates,
which may lead  purchasers  of Common Stock to demand a higher annual yield from
distributions by the Company in relation to the price paid for Common Stock, the
relatively  low daily trading  volume of REITs in general,  including the Common
Stock,  and any  inability  of the  Company to invest the  proceeds  of a future
offering of Securities in a manner that will increase earnings per share.  Sales
of a substantial  number of shares of Common Stock,  or the perception that such
sales could occur,  could adversely affect  prevailing market prices for shares.
The  Company  also may issue  shares of Common  Stock upon  redemption  of Units
issued  in  connection   with  the  formation  of  the  Company  and  subsequent
acquisitions.  In addition,  as of September  30,  1997,  [4,416,900]  shares of
Common  Stock of the Company were  reserved  for issuance  pursuant to stock and
unit  options,  and more shares may be reserved  for such purpose in the future.
These shares will be available for sale in the public  markets from time to time
pursuant to exemptions from registration  requirements or upon registration.  In
connection with the SC-USREALTY Transaction, the Company granted SC-USREALTY the
right to require the Company to file, at any time  requested by  SC-USREALTY,  a
registration  statement  under the Securities Act of 1933 covering all or any of
the shares of Common Stock  acquired by  SC-USREALTY.  No prediction can be made
about the  effect  that  future  sales of Common  Stock  will have on the market
prices of shares.

POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES

     In order to assist the Company in maintaining its  qualification as a REIT,
the Articles of Incorporation  contain certain provisions generally limiting the
ownership  of shares of  capital  stock by any single  shareholder  to 5% of the
outstanding  Common Stock  and/or 5% of any class or series of  Preferred  Stock
(with  exceptions  for  persons who  received  more than 5% of the equity of the
Company pursuant to the contribution of assets to the Company in connection with
the initial public offering of the

                                       8
<PAGE>
Company  and  SC-USREALTY  and its  affiliates).  The  Board  could  waive  this
restriction if it were satisfied that ownership in excess of the above ownership
limit  would  not  jeopardize  the  Company's  status  as a REIT  and the  Board
otherwise  decided  such action  would be in the best  interests of the Company.
Capital  stock  acquired  or  transferred  in breach of the  limitation  will be
automatically  transferred to a trust for the benefit of a designated charitable
beneficiary.  See  'Description of Common  Stock--Restrictions  on Transfer' for
additional  information  regarding  the limits on ownership of shares of capital
stock.

RESTRICTIONS ON ACQUISITION AND CHANGE IN CONTROL

     Various   provisions  of  the  Articles  of   Incorporation   restrict  the
possibility  for  acquisition or change in control of the Company,  even if such
acquisition or change in control were in the stockholders'  interest,  including
the Ownership Limits (as defined  herein),  the staggered terms of the Company's
directors  and the ability of the Board to  authorize  the issuance of preferred
stock without stockholder approval.

                                USE OF PROCEEDS

     Unless otherwise specified in the applicable Prospectus Supplement, the net
proceeds from the sale of the Securities  will be used for the  acquisition  and
development of additional office properties,  as suitable  opportunities  arise,
for the repayment of certain outstanding  indebtedness at such time, for capital
improvements  to property and for working  capital and other  general  corporate
purposes.

                      RATIOS OF EARNINGS TO FIXED CHARGES

     The  Company's  ratio of  earnings  to fixed  charges  for the period  from
February 16, 1993  (commencement of operations) to December 31, 1993 and for the
years ended  December  31,  1994,  1995 and 1996 and for the nine  months  ended
September 30, 1996 and 1997 was 1.75x,  1.81x,  1.91x,  1.74x,  1.74x and 2.01x,
respectively.

     The ratios of earnings to fixed charges were computed by dividing  earnings
by fixed  charges.  For this purpose,  earnings  consist of income (loss) before
gains from sales of property and extraordinary  items plus fixed charges.  Fixed
charges consist of interest expense (including interest costs capitalized),  the
amortization  of debt  issuance  costs and rental  expense  deemed to  represent
interest expense.

     The Company issued preferred stock in 1996 and in August 1997. Accordingly,
the ratio of earnings to combined  fixed charges and preferred  stock  dividends
was 1.71x for the year ended  December  31,  1996 and 1.85x for the nine  months
ended September 30, 1997.

                         DESCRIPTION OF DEBT SECURITIES

     The following  description  sets forth certain general terms and provisions
of the Debt  Securities to which this  Prospectus and any applicable  Prospectus
Supplement may relate. The particular terms of the Debt Securities being offered
and the extent to which such general  provisions  may apply will be set forth in
the applicable  indenture or in one or more indentures  supplemental thereto and
described in a Prospectus Supplement relating to such Debt Securities.

GENERAL

     The Debt  Securities will be direct,  unsecured  obligations of the Company
and may be either senior Debt Securities  ('Senior  Securities') or subordinated
Debt Securities ('Subordinated Securities').  The Debt Securities will be issued
under  one  or  more  indentures  (the  'Indentures').   Senior  Securities  and
Subordinated   Securities  will  be  issued  pursuant  to  separate   indentures
(respectively,  a 'Senior  Indenture' and a 'Subordinated  Indenture'),  in each
case between the Company and a trustee (a  'Trustee').  The  Indentures  will be
subject to and  governed by the Trust  Indenture  Act of 1939,  as amended  (the
'TIA').  The statements made under this heading  relating to the Debt Securities
and the Indentures are summaries of the anticipated  provisions  thereof, do not
purport to be complete and are  qualified in their  entirety by reference to the
Indentures and such Debt Securities. All section references appearing herein are
to sections of each Indenture unless otherwise  indicated and capitalized  terms
used but not defined under this heading shall have the  respective  meanings set
forth in each Indenture.

     The   indebtedness   represented  by   Subordinated   Securities   will  be
subordinated in right of payment to the prior payment in full of the Senior Debt
of the Company as described under '--Subordination' below.

     Except  as  set  forth  in the  applicable  Indenture  or in  one  or  more
indentures  supplemental  thereto  and  described  in  a  Prospectus  Supplement
relating  thereto,  the  Debt  Securities  may be  issued  without  limit  as to
aggregate  principal  amount, in one or more series, in each case as established
from time to time in or pursuant to  authority  granted by a  resolution  of the
Board of the Company or as established in the applicable  Indenture or in one or
more  indentures  supplemental  to such  Indenture.  All Debt  Securities of one
series need not be issued at the same time and,  unless  otherwise  provided,  a
series  may be  reopened,  without  the  consent  of  the  Holders  of the  Debt
Securities of such series,  for issuances of additional  Debt Securities of such
series.

     It is  anticipated  that each Indenture will provide that there may be more
than one  Trustee  thereunder,  each with  respect to one or more series of Debt
Securities. Any Trustee under an Indenture may resign or be removed with respect
to one or more  series  of  Debt  Securities,  and a  successor  Trustee  may be
appointed  to act with  respect  to such  series.  In the event that two or more
persons  are  acting  as  Trustee  with  respect  to  different  series  of Debt
Securities,  each  such  Trustee  shall  be a  director  of a  trust  under  the
applicable Indenture separate and apart from the trust administered by any other
Trustee,  and, except as otherwise indicated herein, any action described herein
to be taken by each  Trustee may be taken by each such  Trustee with respect to,
and only with respect to, the one or more series of Debt Securities for which it
is Trustee under the applicable Indenture.

     The Prospectus  Supplement  relating to any series of Debt Securities being
offered will contain the specific terms thereof, including, without limitation:

          (1) The title of such Debt Securities and whether such Debt Securities
     are Senior Securities or Subordinated Securities;

          (2) The aggregate principal amount of such Debt Securities and any
     limit on such aggregate principal amount;

          (3)  The  percentage  of the  principal  amount  at  which  such  Debt
     Securities will be issued and, if other than the principal  amount thereof,
     the portion of the principal  amount  thereof  payable upon  declaration of
     acceleration of the maturity thereof;

                                       10
<PAGE>
          (4) If  convertible in whole or in part into Common Stock or Preferred
     Stock, the terms on which such Debt Securities are  convertible,  including
     the initial  conversion price or rate (or method for determining the same),
     the  portion  that  is  convertible  and  the  conversion  period,  and any
     applicable  limitations on the ownership or  transferability  of the Common
     Stock or Preferred Stock receivable on conversion;

          (5) The date or dates,  or the  method  for  determining  such date or
     dates, on which the principal of such Debt Securities will be payable;

          (6) The rate or rates (which may be fixed or variable),  or the method
     by  which  such  rate or rates  shall be  determined,  at which  such  Debt
     Securities will bear interest, if any;

          (7) The date or dates,  or the  method  for  determining  such date or
     dates,  from which any such  interest  will accrue,  the dates on which any
     such interest will be payable,  the regular  record dates for such interest
     payment dates,  or the method by which such dates shall be determined,  the
     persons to whom such  interest  shall be payable,  and the basis upon which
     interest shall be calculated if other than that of a 360-day year of twelve
     30-day months;

          (8) The place or places where the principal of (and  premium,  if any)
     and interest,  if any, on such Debt Securities will be payable,  where such
     Debt  Securities  may be  surrendered  for  conversion or  registration  of
     transfer or exchange and where notices or demands to or upon the Company in
     respect of such Debt Securities and the applicable Indenture may be served;

          (9) The period or periods  within which,  the price or prices at which
     and the other terms and conditions  upon which such Debt  Securities may be
     redeemed, in whole or in part, at the option of the Company, if the Company
     is to have such an option;

          (10) The  obligation,  if any,  of the  Company  to  redeem,  repay or
     purchase  such Debt  Securities  pursuant to any sinking  fund or analogous
     provision or at the option of a Holder  thereof,  and the period or periods
     within  which or the date and  dates on which  the price or prices at which
     and the other terms and conditions  upon which such Debt Securities will be
     redeemed,  repaid  or  purchased,  in whole or in  part,  pursuant  to such
     obligation;

          (11) If other than U.S.  dollars,  the currency or currencies in which
     such Debt Securities are  denominated  and payable,  which may be a foreign
     currency or units of two or more foreign currencies or a composite currency
     or currencies, and the terms and conditions relating thereto;

          (12) Whether the amount of payments of principal of (and  premium,  if
     any) or interest,  if any, on such Debt  Securities may be determined  with
     reference to an index,  formula or other method  (which  index,  formula or
     method may, but need not be, based on a currency, currencies, currency unit
     or units or composite  currency or currencies) and the manner in which such
     amounts shall be determined;

          (13) Any additions to, modifications of or deletions from the terms of
     such Debt  Securities  with respect to Events of Default or  covenants  set
     forth in the applicable Indenture;

          (14) Whether such Debt Securities will be issued in certificate or
     book-entry form;

          (15) Whether such Debt Securities will be in registered or bearer form
     and, if in registered form, the denominations  thereof if other than $1,000
     and any integral multiple thereof and, if in bearer form, the denominations
     thereof and terms and conditions relating thereto;

          (16) The applicability, if any, of the defeasance and covenant
     defeasance provisions of Article Fourteen of the applicable Indenture;

          (17)  Whether and under what  circumstances  the Company  will pay any
     additional  amounts  on  such  Debt  Securities  in  respect  of  any  tax,
     assessment or governmental charge and, if so, whether the Company will have
     the option to redeem such Debt  Securities  in lieu of making such payment;
     and

                                       11
<PAGE>
          (18) Any other terms of such Debt Securities not inconsistent with the
     provisions of the applicable Indenture (Section 301).

     The Debt Securities may provide for less than the entire  principal  amount
thereof to be payable upon  declaration of acceleration of the maturity  thereof
('Original Issue Discount  Securities').  Special federal income tax, accounting
and other  considerations  applicable to Original Issue Discount Securities will
be described in the applicable Prospectus Supplement.

     Except  as  set  forth  in the  applicable  Indenture  or in  one  or  more
indentures  supplemental  thereto, the applicable Indenture will not contain any
provisions that would limit the ability of the Company to incur  indebtedness or
that would afford Holders of Debt Securities protection in the event of a highly
leveraged  or similar  transaction  involving  the  Company or in the event of a
change of control.  Restrictions  on ownership  and  transfers of the  Company's
Common Stock and  Preferred  Stock are designed to preserve its status as a REIT
and,  therefore,  may  act to  prevent  or  hinder  a  change  of  control.  See
'Description of Preferred  Stock--Restrictions on Ownership' and 'Description of
Common  Stock--Restrictions  on Transfer.'  Reference is made to the  applicable
Prospectus  Supplement  for  information  with  respect to any  deletions  from,
modifications  of or  additions  to the Events of Default  or  covenants  of the
Company that are described below,  including any addition of a covenant or other
provision providing event risk or similar protection.

DENOMINATION, INTEREST, REGISTRATION AND TRANSFER

     Unless otherwise  described in the applicable  Prospectus  Supplement,  the
Debt  Securities of any series will be issuable in  denominations  of $1,000 and
integral multiples thereof (Section 302).

     Unless otherwise  specified in the applicable  Prospectus  Supplement,  the
principal of (and applicable premium, if any) and interest on any series of Debt
Securities  will be payable at the  corporate  trust office of the Trustee,  the
address  of  which  will be  stated  in the  applicable  Prospectus  Supplement;
provided that, at the option of the Company,  payment of interest may be made by
check mailed to the address of the person entitled  thereto as it appears in the
applicable  register for such Debt  Securities  or by wire  transfer of funds to
such person at an account  maintained  within the United States  (Sections  301,
305, 306, 307 and 1002).

     Any  interest  not  punctually  paid or duly  provided  for on any Interest
Payment  Date  with  respect  to a Debt  Security  ('Defaulted  Interest')  will
forthwith  cease to be payable to the Holder on the  applicable  regular  record
date and may either be paid to the person in whose  name such Debt  Security  is
registered  at the close of  business  on a special  record  date (the  'Special
Record  Date') for the  payment of such  Defaulted  Interest  to be fixed by the
Trustee,  notice  whereof shall be given to the Holder of such Debt Security not
less than ten days prior to such Special Record Date, or may be paid at any time
in any other lawful manner,  all as more  completely  described in the Indenture
(Section 307).

     Subject to  certain  limitations  imposed  upon Debt  Securities  issued in
book-entry  form,  the Debt  Securities of any series will be  exchangeable  for
other  Debt  Securities  of the same  series and of a like  aggregate  principal
amount and tenor of different  authorized  denominations  upon surrender of such
Debt Securities at the corporate trust office of the applicable Trustee referred
to  above.  In  addition,  subject  to  certain  limitations  imposed  upon Debt
Securities  issued in book-entry  form, the Debt Securities of any series may be
surrendered for conversion or  registration  of transfer or exchange  thereof at
the  corporate  trust  office of the  applicable  Trustee.  Every Debt  Security
surrendered  for  conversion,  registration of transfer or exchange must be duly
endorsed or accompanied by a written  instrument of transfer.  No service charge
will  be  made  for  any  registration  of  transfer  or  exchange  of any  Debt
Securities, but the Company may require payment of a sum sufficient to cover any
tax or  other  governmental  charge  payable  in  connection  therewith.  If the
applicable  Prospectus  Supplement  refers to any transfer agent (in addition to
the applicable Trustee) initially  designated by the Company with respect to any
series of Debt  Securities,  the Company may at any time rescind the designation
of any such transfer agent or approve a change in the location through which any
such transfer agent acts, except that the Company will be required to maintain a
transfer agent in each place of payment for such

                                       12
<PAGE>
series.  The Company may at any time designate  additional  transfer agents with
respect to any series of Debt Securities (Section 1002).

     Neither  the  Company  nor any  Trustee  shall be  required  to (i)  issue,
register  the transfer of or exchange  Debt  Securities  of any series  during a
period beginning at the opening of business 15 days before any selection of Debt
Securities  of that series to be redeemed and ending at the close of business on
the day of mailing of the  relevant  notice of  redemption;  (ii)  register  the
transfer  of or  exchange  any Debt  Security,  or portion  thereof,  called for
redemption, except the unredeemed portion of any Debt Security being redeemed in
part;  or (iii) issue,  register  the transfer of or exchange any Debt  Security
that has been surrendered for repayment at the option of the Holder,  except the
portion, if any, of such Debt Security not to be so repaid (Section 305).

MERGER, CONSOLIDATION OR SALE

     The Company will be permitted to consolidate with, or sell, lease or convey
all or  substantially  all of its assets  to, or merge  with or into,  any other
entity provided that (a) either the Company shall be the continuing  entity,  or
the successor entity (if other than the Company) formed by or resulting from any
such  consolidation  or merger or which shall have received the transfer of such
assets shall expressly assume payment of the principal of (and premium,  if any)
and interest on all of the Debt Securities and the due and punctual  performance
and  observance  of  all of the  covenants  and  conditions  contained  in  each
Indenture;  (b) immediately after giving effect to such transaction and treating
any indebtedness  that becomes an obligation of the Company or any Subsidiary as
a result  thereof as having been  incurred by the Company or  Subsidiary  at the
time of such transaction, no Event of Default under the Indentures, and no event
which, after notice or the lapse of time, or both, would become such an Event of
Default, shall have occurred and be continuing; and (c) an officer's certificate
and legal opinion  covering such  conditions  shall be delivered to each Trustee
(Sections 801 and 803).

CERTAIN COVENANTS

     Existence.  Except as described  under  '--Merger,  Consolidation  or Sale'
above,  the  Company  will be  required  to do or cause  to be done  all  things
necessary  to preserve and keep in full force and effect its  existence,  rights
(by articles of  incorporation,  by-laws and statute) and franchises;  provided,
however,  that the  Company  shall  not be  required  to  preserve  any right or
franchise if it determines that the preservation  thereof is no longer desirable
in the conduct of its business and that the loss thereof is not  disadvantageous
in any material respect to the Holders of the Debt Securities.

     Maintenance of Properties. The Company will be required to cause all of its
material  properties  used or  useful  in the  conduct  of its  business  or the
business of any  Subsidiary (as defined below) 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 (Section  1007);  provided,
however,  that the Company  shall not be  prevented  from  selling or  otherwise
disposing for value its properties in the ordinary course of business.

of  recognized  responsibility  and, if described in the  applicable  Prospectus
Supplement, having a specified rating from a recognized insurance rating service
(Section 1008).

     Payment of Taxes and Other  Claims.  The Company will be required to pay or
discharge  or cause to be paid or  discharged,  before  the  same  shall  become

imposed upon it or any Subsidiary or upon the income, profits or property of the
Company or any Subsidiary,  and (ii) all lawful claims for labor,  materials and

Company or any  Subsidiary;  provided,  however,  that the Company  shall not be
required to pay or discharge or cause to be paid or

                                       13

required to file with the  Commission  pursuant to such  Sections 13 or 15(d) if
the Company were so subject (the 'Financial Information'),  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 also will in any event (x)

prospective Holder (Section 1010).

ADDITIONAL COVENANTS AND/OR MODIFICATIONS TO THE COVENANTS DESCRIBED ABOVE

     Any  additional  covenants  of  the  Company  and/or  modifications  to the
covenants described above with respect to any Debt Securities or series thereof,
including any covenants relating to limitations on incurrence of indebtedness or
other financial  covenants,  will be set forth in the applicable Indenture or an
indenture  supplemental  thereto  and  described  in the  Prospectus  Supplement
relating thereto.

EVENTS OF DEFAULT, NOTICE AND WAIVER

     Each  Indenture  will  provide  that the  following  events are  'Events of
Default' with respect to any series of Debt Securities  issued  thereunder:  (i)
default in the payment of any  installment  of interest on any Debt  Security of
such series;  (ii)  default in the payment of principal of (or premium,  if any,
on) any Debt  Security  of such series when due and  payable;  (iii)  default in
making any  sinking  fund  payment as  required  for any Debt  Security  of such
series;  (iv) default in the  performance,  or breach,  of any other covenant or
warranty of the Company  contained  in the  applicable  Indenture  (other than a
covenant  added to the  Indenture  solely  for the  benefit  of a series of Debt
Securities  issued  thereunder  other than such  series),  continued for 60 days
after written notice as provided in the applicable Indenture;  (v) 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) representing recourse indebtedness or
indebtedness guaranteed by such party 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;   (vi)  certain  events  of
bankruptcy,  insolvency or  reorganization,  or court appointment of a receiver,
liquidator or trustee of the Company or any  Significant  Subsidiary (as defined
below)  for all or  substantially  all of the  property  of the  Company  or any
Significant  Subsidiary;  and (vii) any other  Event of  Default  provided  with
respect to a particular series of Debt Securities (Section 501).

     'Significant  Subsidiary'  means  any  Subsidiary  that  is a  'significant
subsidiary'  (within  the  meaning  of  Regulation  S-X  promulgated  under  the
Securities Act) of the Company.

     'Subsidiary' means a corporation, partnership or other entity a majority of
the voting  power of the voting  equity  securities  or the  outstanding  equity
interests of which are owned,  directly or indirectly,  by the Company or by one
or more other Subsidiaries of the Company. For the purposes of this definition,

                                       14
<PAGE>
'voting equity  securities'  means equity securities having voting power for the
election of  directors,  whether at all times or only so long as no senior class
of  security  has such  voting  power by  reason  of any  contingency.  The term
'Subsidiary' does not include Carr Services,  Inc. or CarrAmerica  Development &
Construction  as  the  Company  does  not  own  or  control  a  majority  of the
outstanding voting stock of such entities.

     If an Event of Default under any Indenture with respect to Debt  Securities
of any series at the time  outstanding  occurs and is continuing,  then in every
such case the  applicable  Trustee  or the  Holders  of not less than 25% of the
principal amount of the Outstanding Debt Securities of that series will have the
right to declare the principal amount (or, if the Debt Securities of that series
are Original Issue Discount  Securities or indexed  securities,  such portion of
the principal  amount as may be specified in the terms  thereof) of all the Debt
Securities of that series to be due and payable  immediately  by written  notice
thereof to the Company (and to the applicable  Trustee if given by the Holders).
However,  at any time after such a declaration of  acceleration  with respect to
Debt Securities of such series (or of all Debt Securities then Outstanding under
any  Indenture,  as the case may be) has been made,  but  before a  judgment  or
decree for payment of the money due has been obtained by the applicable Trustee,
the Holders of not less than a majority in principal  amount of Outstanding Debt
Securities of such series (or of all Debt Securities then Outstanding  under the
applicable Indenture, as the case may be) may rescind and annul such declaration
and its consequences if (a) the Company shall have deposited with the applicable
Trustee all  required  payments of the  principal of (and  premium,  if any) and
interest on the Debt  Securities of such series (or of all Debt  Securities then
Outstanding  under the applicable  Indenture,  as the case may be), plus certain
fees, expenses, disbursements and advances of the applicable Trustee and (b) all
events of default,  other than the  non-payment  of  accelerated  principal  (or
specified portion  thereof),  with respect to Debt Securities of such series (or
of all Debt Securities then Outstanding under the applicable  Indenture,  as the
case may be) have been cured or waived as  provided in such  Indenture  (Section
502).  Each  Indenture  also will  provide  that the  Holders of not less than a
majority in principal  amount of the  Outstanding  Debt Securities of any series
(or of all Debt Securities then Outstanding under the applicable  Indenture,  as
the case may be) may waive any past  default with respect to such series and its
consequences,  except a  default  (x) in the  payment  of the  principal  of (or
premium,  if any) or  interest  on any Debt  Security  of such  series or (y) in
respect of a covenant or provision  contained in the  applicable  Indenture that
cannot  be  modified  or  amended  without  the  consent  of the  Holder of each
Outstanding Debt Security affected thereby (Section 513).

     Each  Trustee  will be  required  to give  notice  to the  Holders  of Debt
Securities  within 90 days of a default under the  applicable  Indenture  unless
such  default  shall  have been cured or waived;  provided,  however,  that such
Trustee may withhold  notice to the Holders of any series of Debt  Securities of
any default with respect to such series  (except a default in the payment of the
principal  of (or  premium,  if any) or  interest  on any Debt  Security of such
series or in the payment of any sinking fund  installment in respect of any Debt
Security of such  series) if  specified  responsible  officers  of such  Trustee
consider such withholding to be in the interest of such Holders (Section 601).

     Each  Indenture  will  provide  that no Holders of Debt  Securities  of any
series may institute  any  proceedings,  judicial or otherwise,  with respect to
such Indenture or for any remedy  thereunder,  except in the cases of failure of
the  applicable  Trustee,  for 60 days,  to act after it has  received a written
request to  institute  proceedings  in  respect of an Event of Default  from the
Holders  of not less  than  25% in  principal  amount  of the  Outstanding  Debt
Securities  of  such  series,  as  well  as an  offer  of  indemnity  reasonably
satisfactory to it (Section 507). This provision will not prevent,  however, any
Holder of Debt Securities from  instituting  suit for the enforcement of payment
of the principal of (and premium,  if any) and interest on such Debt  Securities
at the respective due dates thereof (Section 508).

     Subject to provisions in each  Indenture  relating to its duties in case of
default,  no Trustee will be under any  obligation to exercise any of its rights
or powers  under an  Indenture at the request or direction of any Holders of any
series of Debt Securities  then  Outstanding  under such Indenture,  unless such
Holders  shall have  offered to the Trustee  thereunder  reasonable  security or
indemnity  (Section  602).  The Holders of not less than a majority in principal
amount  of the  Outstanding  Debt  Securities  of  any  series  (or of all  Debt
Securities then Outstanding under an Indenture, as the case may

                                       15
<PAGE>
be) shall have the right to direct the time,  method and place of conducting any
proceeding for any remedy available to the applicable  Trustee, or of exercising
any trust or power conferred upon such Trustee. However, a Trustee may refuse to
follow  any  direction  which  is in  conflict  with  any law or the  applicable
Indenture,  which may involve such Trustee in personal liability or which may be
unduly  prejudicial to the Holders of Debt Securities of such series not joining
therein (Section 512).

     Within 120 days after the close of each fiscal  year,  the Company  will be
required  to deliver  to each  Trustee a  certificate,  signed by one of several
specified  officers,  stating  whether or not such officer has  knowledge of any
default under the applicable  Indenture and, if so, specifying each such default
and the nature and status thereof (Section 1011).

MODIFICATION OF THE INDENTURES

     Modifications  and  amendments of an Indenture will be permitted to be made
only with the consent of the  Holders of not less than a majority  in  principal
amount of all Outstanding Debt Securities  issued under such Indenture which are
affected by such  modification  or amendment;  provided,  however,  that no such
modification  or amendment  may,  without the consent of the Holder of each such
Debt Security affected thereby,  (a) change the stated maturity of the principal
of, or any  installment  of  interest  (or  premium,  if any) on,  any such Debt
Security;  (b) reduce the principal amount of, or the rate or amount of interest
on, or any premium  payable on redemption of, any such Debt Security,  or reduce
the amount of principal of an Original Issue Discount Security that would be due
and payable upon declaration of acceleration of the maturity thereof or would be
provable in bankruptcy, or adversely affect any right of repayment of the Holder
of any such Debt  Security;  (c)  change  the place of  payment,  or the coin or
currency,  for payment of the  principal of (or premium,  if any) or interest on
any  such  Debt  Security;  (d)  impair  the  right  to  institute  suit for the
enforcement  of any payment on or with  respect to any such Debt  Security;  (e)
reduce the above-stated  percentage of Outstanding Debt Securities of any series
necessary to modify or amend the applicable Indenture,  to waive compliance with
certain provisions thereof or certain defaults and consequences thereunder or to
reduce the quorum or voting requirements set forth in the applicable  Indenture;
or (f) modify any of the foregoing  provisions or any of the provisions relating
to the waiver of certain past defaults or certain covenants,  except to increase
the required  percentage  to effect such action or to provide that certain other
provisions  may not be modified  or waived  without the consent of the Holder of
such Debt Security (Section 902).

     The Holders of not less than a majority in principal  amount of Outstanding
Debt  Securities  of each series  affected  thereby will have the right to waive
compliance  by the Company with certain  covenants  in such  Indenture  (Section
1013).

     Modifications  and  amendments of an Indenture will be permitted to be made
by the Company and the respective  Trustee thereunder without the consent of any
Holder of Debt Securities for any of the following purposes: (i) to evidence the
succession  of another  person to the Company as obligor  under such  Indenture;
(ii) to add to the  covenants  of the  Company for the benefit of the Holders of
all or any  series  of Debt  Securities  or to  surrender  any  right  or  power
conferred upon the Company in the Indenture;  (iii) to add Events of Default for
the benefit of the Holders of all or any series of Debt Securities;  (iv) to add
or change any  provisions of an Indenture to  facilitate  the issuance of, or to
liberalize  certain  terms of, Debt  Securities  in bearer form, or to permit or
facilitate the issuance of Debt Securities in uncertificated form, provided that
such action shall not adversely  affect the interests of the Holders of the Debt
Securities of any series in any material respect; (v) to change or eliminate any
provisions of an Indenture,  provided that any such change or elimination  shall
become  effective  only when  there are no Debt  Securities  Outstanding  of any
series  created  prior  thereto  which  are  entitled  to the  benefit  of  such
provision;  (vi) to secure the Debt  Securities;  (vii) to establish the form or
terms of Debt Securities of any series, including the provisions and procedures,
if applicable,  for the conversion of such Debt  Securities into Common Stock or
Preferred  Stock  of the  Company;  (viii)  to  provide  for the  acceptance  of
appointment  by a successor  Trustee or  facilitate  the  administration  of the
trusts under an Indenture by more than one Trustee;  (ix) to cure any ambiguity,
defect or  inconsistency  in an  Indenture,  provided that such action shall not
adversely  affect the  interests  of Holders  of Debt  Securities  of any series
issued under such Indenture in any material respect; or (x) to supplement any of
the provisions of

                                       16
<PAGE>
an Indenture  to the extent  necessary to permit or  facilitate  defeasance  and
discharge of any series of such Debt Securities, provided that such action shall
not adversely  affect the interests of the Holders of the Debt Securities of any
series in any material respect (Section 901).

     Each Indenture will provide that in determining  whether the Holders of the
requisite principal amount of Outstanding Debt Securities of a series have given
any  request,  demand,  authorization,  direction,  notice,  consent  or  waiver
thereunder  or  whether a quorum is  present  at a meeting  of  Holders  of Debt
Securities, (i) the principal amount of an Original Issue Discount Security that
shall be deemed to be Outstanding  shall be the amount of the principal  thereof
that  would  be due  and  payable  as of the  date of  such  determination  upon
declaration of acceleration of the maturity  thereof,  (ii) the principal amount
of any Debt  Security  denominated  in a foreign  currency  that shall be deemed
Outstanding  shall be the U.S. dollar  equivalent,  determined on the issue date
for such Debt Security,  of the principal amount (or, in the case of an Original
Issue Discount  Security,  the U.S. dollar  equivalent on the issue date of such
Debt  Security of the amount  determined  as  provided in (i) above),  (iii) the
principal amount of an indexed security that shall be deemed  Outstanding  shall
be the  principal  face amount of such  indexed  security at original  issuance,
unless otherwise  provided with respect to such indexed security pursuant to the
applicable Indenture, and (iv) Debt Securities owned by the Company or any other
obligor  under the Debt  Securities  or any  affiliate of the Company or of such
other obligor shall be disregarded.

     Each  Indenture  will  contain  provisions  for  convening  meetings of the
Holders  of Debt  Securities  of a  series  (Section  501).  A  meeting  will be
permitted to be called at any time by the  applicable  Trustee,  and also,  upon
request,  by the Company or the Holders of at least 10% in  principal  amount of
the  Outstanding  Debt  Securities of such series,  in any such case upon notice
given as provided in the Indenture. Except for any consent that must be given by
the  Holder  of  each  Debt  Security  affected  by  certain  modifications  and
amendments of an Indenture,  any resolution  presented at a meeting or adjourned
meeting  duly  reconvened  at which a quorum is  present  may be  adopted by the
affirmative  vote of the  Holders  of a  majority  in  principal  amount  of the
Outstanding Debt Securities of that series;  provided,  however, that, except as
referred  to  above,  any  resolution  with  respect  to  any  request,  demand,
authorization,  direction,  notice,  consent, waiver or other action that may be
made,  given or taken by the  Holders of a specified  percentage,  which is less
than a majority,  in principal  amount of the  Outstanding  Debt Securities of a
series may be adopted at a meeting or  adjourned  meeting or  adjourned  meeting
duly  reconvened  at which a quorum is  present by the  affirmative  vote of the
Holders of such specified percentage in principal amount of the Outstanding Debt
Securities  of that  series.  Any  resolution  passed or  decision  taken at any
meeting of Holders of Debt Securities of any series duly held in accordance with
an Indenture  will be binding on all Holders of Debt  Securities of that series.
The quorum at any meeting  called to adopt a resolution,  and at any  reconvened
meeting,  will be persons holding or representing a majority in principal amount
of the Outstanding Debt Securities of a series;  provided,  however, that if any
action is to be taken at such  meeting with respect to a consent or waiver which
may be given by the Holders of not less than a specified percentage in principal
amount of the Outstanding  Debt  Securities of a series,  the persons holding or
representing  such specified  percentage in principal  amount of the Outstanding
Debt Securities of such series will constitute a quorum.

     Notwithstanding the foregoing provisions,  each Indenture will provide that
if any action is to be taken at a meeting of Holders of Debt  Securities  of any
series with respect to any request, demand,  authorization,  direction,  notice,
consent,  waiver and other action that such Indenture  expressly provides may be
made,  given or taken by the  Holders of a  specified  percentage  in  principal
amount of all Outstanding Debt Securities  affected  thereby,  or 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  Debt  Securities 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 such Indenture.

SUBORDINATION

     The terms and  conditions,  if any,  upon  which  the Debt  Securities  are
subordinated  to other  indebtedness  of the  Company  will be set  forth in the
applicable  Prospectus  Supplement  relating thereto.  Such terms will include a
description  of the  indebtedness  ranking  senior to the Debt  Securities,  the
restrictions on payments to the Holders of such Debt Securities  while a default
with respect to such senior  indebtedness in continuing,  the  restrictions,  if
any, on payments to the Holders of such Debt  Securities  following  an Event of
Default,  and  provisions  requiring  Holders of such Debt  Securities  to remit
certain payments to holders of senior indebtedness.

DISCHARGE, DEFEASANCE AND COVENANT DEFEASANCE

     The Company may be permitted  under the  applicable  Indenture to discharge
certain  obligations  to  Holders  of  any  series  of  Debt  Securities  issued
thereunder  that have not already been delivered to the  applicable  Trustee for
cancellation  and that either have become due and payable or will become due and
payable  within  one year (or  scheduled  for  redemption  within  one  year) by
irrevocably  depositing  with the applicable  Trustee,  in trust,  funds in such
currency  or  currencies,  currency  unit or  units  or  composite  currency  or
currencies in which such Debt Securities are payable in an amount  sufficient to
pay the entire indebtedness on such Debt Securities in respect of principal (and
premium,  if any)  and  interest  to the  date of such  deposit  (if  such  Debt
Securities  have become due and payable) or to the stated maturity or redemption
date, as the case may be.

     Each Indenture will provide that, if the provisions of Article Fourteen are
made  applicable  to the Debt  Securities  of or within any series  pursuant  to
Section 301 of such  Indenture,  the Company may elect either (a) to defease and
be discharged from any and all obligations  with respect to such Debt Securities
(except  for  the  obligation  to pay  additional  amounts,  if  any,  upon  the
occurrence  of certain  events of tax,  assessment or  governmental  charge with
respect to payments on such Debt Securities, and the obligations to register the
transfer or exchange of such Debt Securities, to replace temporary or mutilated,
destroyed,  lost or stolen Debt  Securities,  to maintain an office or agency in
respect  of such  Debt  Securities  and to hold  moneys  for  payment  in trust)
('defeasance')  (Section 1402) or (b) to be released from its  obligations  with
respect to such Debt Securities under certain specified  sections of Article Ten
of such Indenture as specified in the applicable  Prospectus  Supplement and any
omission  to comply  with such  obligations  shall  not  constitute  an Event of
Default with respect to such Debt Securities  ('covenant  defeasance')  (Section
1403),  in either  case upon the  irrevocable  deposit by the  Company  with the
applicable  Trustee,  in trust,  of an amount,  in such currency or  currencies,
currency  unit or units or composite  currency or  currencies in which such Debt
Securities are payable at stated maturity, or Government Obligations (as defined
below), or both,  applicable to such Debt Securities which through the scheduled
payment of principal  and interest in  accordance  with their terms will provide
money in an amount sufficient without  reinvestment to pay the principal of (and
premium, if any) and interest on such Debt Securities, and any mandatory sinking
fund or analogous payments thereon, on the scheduled due dates therefor.

     Such a trust will only be  permitted  to be  established  if,  among  other
things,  the  Company  has  delivered  to the  applicable  Trustee an opinion of
counsel  (as  specified  in the  applicable  Indenture)  to the effect  that the
Holders of such Debt  Securities  will not  recognize  income,  gain or loss for
federal  income  tax  purposes  as a  result  of  such  defeasance  or  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 defeasance
or covenant  defeasance  had not occurred,  and such opinion of counsel,  in the
case of  defeasance,  will be required to refer to and be based upon a ruling of
the Internal  Revenue Service or a change in applicable U.S.  federal income tax
law occurring after the date of the Indenture (Section 1404).

     'Government  Obligations' means securities which are (i) direct obligations
of the United  States of  America or the  government  which  issued the  foreign
currency in which the Debt  Securities of a particular  series are payable,  for
the payment of which its full faith and credit is pledged or (ii) obligations of
a person controlled or supervised by and acting as an agency or  instrumentality
of the

                                       18
<PAGE>
United States of America or such government which issued the foreign currency in
which the Debt  Securities  of such series are  payable,  the timely  payment of
which is unconditionally guaranteed as a full faith and credit obligation of the
United  States of America or such  government,  which,  in either case,  are not
callable  or  redeemable  at the  option of the issuer  thereof,  and shall also
include a depository receipt issued by a bank or trust company as custodian with
respect to any such Government  Obligation or a specific  payment of interest on
or principal of any such  Government  Obligation  held by such custodian for the
account of the Holder of a depository receipt, provided that (except as required
by applicable  law) such  custodian is not authorized to make any deduction from
the  amount  payable to the Holder of such  depository  receipt  from any amount
received  by the  custodian  in  respect  of the  Government  Obligation  or the
specific  payment of  interest  on or  principal  of the  Government  Obligation
evidenced by such depository receipt (Section 101).

     Unless otherwise provided in the applicable Prospectus Supplement, if after
the  Company  has  deposited  funds  and/or  Government  Obligations  to  effect
defeasance or covenant defeasance with respect to Debt Securities of any series,
(a) the Holder of a Debt Security of such series is entitled to, and does, elect
pursuant  to the  applicable  Indenture  or the terms of such Debt  Security  to
receive  payment in a currency,  currency unit or composite  currency other than
that in which such  deposit has been made in respect of such Debt  Security,  or
(b) a Conversion  Event (as defined  below)  occurs in respect of the  currency,
currency  unit or composite  currency in which such  deposit has been made,  the
indebtedness  represented by such Debt Security will be deemed to have been, and
will be, fully discharged and satisfied  through the payment of the principal of
(and premium,  if any) and interest on such Debt Security as they become due out
of the proceeds yielded by converting the amount so deposited in respect of such
Debt Security into the  currency,  currency unit or composite  currency in which
such  Debt  Security  becomes  payable  as a  result  of such  election  or such
cessation of usage based on the applicable  market  exchange  rate.  'Conversion
Event' means the cessation of use of (i) a currency,  currency unit or composite
currency  both by the  government  of the country which issued such currency and
for  the  settlement  of   transactions  by  a  central  bank  or  other  public
institutions of or within the international banking community, (ii) the ECU both
within the European  Monetary  System and for the settlement of  transactions by
public institutions of or within the European  Communities or (iii) any currency
unit or composite  currency other than the ECU for the purposes for which it was
established.  Unless otherwise provided in the applicable Prospectus Supplement,
all  payments of  principal  of (and  premium,  if any) and interest on any Debt
Security  that is payable in a foreign  currency  that  ceases to be used by its
government of issuance shall be made in U.S. dollars.

     In the event the Company  effects  covenant  defeasance with respect to any
Debt Securities and such Debt Securities are declared due and payable because of
the occurrence of any Event of Default other than the Event of Default described
in clause (iv) under '--Events of Default, Notice and Waiver' above with respect
to certain  specified  sections of Article Ten of each Indenture (which sections
would no  longer  be  applicable  to such  Debt  Securities  as a result of such
covenant  defeasance)  or described in clause (vii) under  '--Events of Default,
Notice and Waiver'  above with  respect to any other  covenant as to which there
has been  covenant  defeasance,  the amount in such  currency,  currency unit or
composite  currency in which such Debt  Securities  are payable,  and Government
Obligations  on deposit with the applicable  Trustee,  will be sufficient to pay
amounts due on such Debt Securities at the time of their stated maturity but may
not be sufficient to pay amounts due on such Debt  Securities at the time of the
acceleration  resulting  from such  Default.  However,  the Company would remain
liable to make payment of such amounts due at the time of acceleration.

     The applicable  Prospectus  Supplement may further describe the provisions,
if any,  permitting  such  defeasance  or  covenant  defeasance,  including  any
modifications  to the  provisions  described  above,  with  respect  to the Debt
Securities of or within a particular series.

CONVERSION RIGHTS

     The terms and  conditions,  if any,  upon  which  the Debt  Securities  are
convertible  into  Common  Stock or  Preferred  Stock  will be set  forth in the
applicable  Prospectus  Supplement  relating  thereto.  Such terms will  include
whether  such Debt  Securities  are  convertible  into Common Stock or Preferred
Stock,

                                       19
<PAGE>
the conversion price (or manner of calculation thereof),  the conversion period,
provisions as to whether  conversion will be at the option of the Holders or the
Company,  the  events  requiring  an  adjustment  of the  conversion  price  and
provisions  affecting  conversion  in the event of the  redemption  of such Debt
Securities and any restrictions on conversion,  including  restrictions directed
at maintaining the Company's REIT status.

REDEMPTION OF SECURITIES

     The Indenture provides that the Debt Securities may be redeemed at any time
at the option of the  Company,  in whole or in part,  at the  redemption  price,
except as may  otherwise be provided in connection  with any Debt  Securities or
series thereof.

     From and after notice has been given as provided in the Indenture, if funds
for the redemption of any Debt Securities  called for redemption shall have been
made available on such redemption  date, such Debt Securities will cease to bear
interest on the date fixed for such redemption specified in such notice, and the
only right of the Holders of the Debt  Securities  will be to receive payment of
the redemption price.

     Notice of any optional  redemption of any Debt  Securities will be given to
Holders at their  addresses,  as shown in the Company's  books and records,  not
more than 60 nor less than 30 days prior to the date fixed for  redemption.  The
notice of redemption will specify,  among other items,  the redemption price and
the principal amount of the Debt Securities held by such Holder to be redeemed.

     If the Company elects to redeem Debt Securities, it will notify the Trustee
at least 45 days  prior to the  redemption  date  (or  such  shorter  period  as
satisfactory  to  the  Trustee)  of  the  aggregate  principal  amount  of  Debt
Securities to be redeemed and the redemption  date. If less than all of the Debt
Securities are to be redeemed,  the Trustee shall select the Debt  Securities to
be  redeemed  pro  rata,  by lot or in such  manner  as it shall  deem  fair and
appropriate.

                         DESCRIPTION OF PREFERRED STOCK

     The Company is authorized to issue 15,000,000 shares of Preferred Stock. As
of  September  30,  1997,  there  were  780,000  shares of  Series A  Cumulative
Convertible  Redeemable  Preferred  Stock issued and  outstanding  and 8,000,000
shares of Series B Cumulative Redeemable Preferred Stock issued and outstanding.

     Under the Company's  Articles of Incorporation,  the Board may from time to
time  establish and issue one or more series of Preferred  Stock.  The Board may
classify or reclassify any unissued  Preferred  Stock by setting or changing the
number,  designation,  preference,  conversion or other rights,  voting  powers,
restrictions,   limitations  as  to  dividends,   qualifications  and  terms  or
conditions of redemption of such series (a 'Designating Amendment').

     The following description of the Preferred Stock sets forth certain general
terms and provisions of the Preferred  Stock to which any Prospectus  Supplement
may relate.  The  statements  below  describing  the Preferred  Stock are in all
respects  subject  to and  qualified  in  their  entirety  by  reference  to the
applicable  provisions  of the  Company's  Articles  of  Incorporation  and  the
Company's bylaws (the 'Bylaws').

GENERAL

     The Board is  empowered  by the  Company's  Articles  of  Incorporation  to
designate  and issue  from time to time one or more  series of  Preferred  Stock
without  stockholder  approval.  The Board may  determine  the relative  rights,
preferences and privileges of each series of Preferred Stock so issued.  Because
the Board has the power to establish the  preferences  and rights of each series
of Preferred  Stock,  it may afford the holders of any series of Preferred Stock
preferences,  powers and rights,  voting or  otherwise,  senior to the rights of
holders of Common Stock.  The Preferred Stock will,  when issued,  be fully paid
and nonassessable.

     The Prospectus  Supplement  relating to any Preferred Stock offered thereby
will contain the specific terms thereof, including, without limitation:

          (1) The title and stated value of such Preferred Stock;

          (2)  The  number  of such  shares  of  Preferred  Stock  offered,  the
     liquidation  preference  per share and the offering price of such Preferred
     Stock;

          (3)  The  dividend  rate(s),   period(s)  and/or  payment  date(s)  or
     method(s) of calculation thereof applicable to such Preferred Stock;

          (4) The date from which dividends on such Preferred Stock will
     accumulate, if applicable;

          (5) The procedures for any auction and remarketing, if any, for such
     Preferred Stock;

          (6) The provision for a sinking fund, if any, for such Preferred
     Stock;

          (7) The provision for redemption, if applicable, of such Preferred
     Stock;

          (8) Any listing of such Preferred Stock on any securities exchange;

          (9) The terms and conditions, if applicable, upon which such Preferred
     Stock will be convertible  into Common Stock of the Company,  including the
     conversion price (or manner of calculation thereof);

          (10) Any other specific terms, preferences, rights, limitations or
     restrictions of such Preferred Stock;

          (11) A discussion of federal income tax considerations applicable to
     such Preferred Stock;

          (12) The relative  ranking and  preferences of such Preferred Stock as
     to dividend rights and rights upon  liquidation,  dissolution or winding up
     of the affairs of the Company;

                                       21
<PAGE>
          (13) Any  limitations  on  issuance of any series of  Preferred  Stock
     ranking senior to or on a parity with such series of Preferred  Stock as to
     dividend rights and rights upon  liquidation,  dissolution or winding up of
     the affairs of the Company; and

          (14)  Any   limitations   on  direct  or   beneficial   ownership  and
     restrictions  on transfer,  in each case as may be  appropriate to preserve
     the status of the Company as a REIT.

RANK

     Unless  otherwise  specified in the  Prospectus  Supplement,  the Preferred
Stock  will,  with  respect to  dividend  rights and  rights  upon  liquidation,
dissolution  or winding  up of the  Company,  rank (i) senior to all  classes or
series of Common  Stock of the  Company,  and to all equity  securities  ranking
junior to such  Preferred  Stock,  (ii) on a parity  with all equity  securities
issued by the Company the terms of which  specifically  provide that such equity
securities  rank on a parity with the Preferred  Stock,  and (iii) junior to all
equity securities issued by the Company the terms of which specifically  provide
that such equity securities rank senior to the Preferred Stock. The term 'equity
securities' does not include convertible debt securities.

DIVIDENDS

     Holders of the Preferred  Stock of each series will be entitled to receive,
when,  as and if  declared by the Board,  out of assets of the  Company  legally
available for payment, cash dividends (or dividends in kind or in other property
if expressly permitted and described in the applicable Prospectus Supplement) at
such rates and on such dates as will be set forth in the  applicable  Prospectus
Supplement.  Each such  dividend  will be  payable  to holders of record as they
appear on the stock  transfer  books of the Company on such record  dates as are
fixed by the Board.

     Dividends  on  any  series  of  Preferred   Stock  may  be   cumulative  or
non-cumulative,  as provided in the applicable Prospectus Supplement. Dividends,
if  cumulative,  will be  cumulative  from and  after  the date set forth in the
applicable  Prospectus  Supplement.  If the Board  fails to  declare a  dividend
payable on a dividend  payment  date on any  series of the  Preferred  Stock for
which  dividends  are  non-cumulative,  then the  holders of such  series of the
Preferred  Stock  will have no right to  receive a  dividend  in  respect of the
dividend period ending on such dividend  payment date, and the Company will have
no  obligation  to pay the  dividend  accrued  for such  period,  whether or not
dividends on such series are  declared  payable on any future  dividend  payment
date.

     Unless otherwise specified in the Prospectus  Supplement,  if any shares of
Preferred  Stock  of any  series  are  outstanding,  no full  dividends  will be
declared or paid or set apart for payment on any capital stock of the Company of
any other series  ranking,  as to  dividends,  on a parity with or junior to the
Preferred  Stock of such  series  for any period  unless  (i) if such  series of
Preferred Stock has a cumulative  dividend,  full cumulative dividends have been
or contemporaneously  are declared and paid or declared and a sum sufficient for
the payment  thereof set apart for such payment on the  Preferred  Stock of such
series for all past  dividend  periods and the then current  dividend  period or
(ii) if such series of Preferred Stock does not have a cumulative dividend, full
dividends for the then current  dividend  period have been or  contemporaneously
are declared and paid or declared and a sum sufficient  for the payment  thereof
set apart for such payment on the Preferred Stock of such series. When dividends
are not paid in full (or a sum  sufficient  for such full  payment is not so set
apart) upon Preferred  Stock of any series and the shares of any other series of
Preferred  Stock ranking on a parity as to dividends with the Preferred Stock of
such series,  all dividends declared upon Preferred Stock of such series and any
other series of Preferred  Stock  ranking on a parity as to dividends  with such
Preferred  Stock  will be  declared  pro rata so that the  amount  of  dividends
declared  per share of  Preferred  Stock of such series and such other series of
Preferred Stock will in all cases bear to each other the same ratio that accrued
dividends  per  share on the  Preferred  Stock of such  series  (which  will not
include  any  accumulation  in respect of unpaid  dividends  for prior  dividend
periods if such  Preferred  Stock do not have a  cumulative  dividend)  and such
other series of Preferred Stock bear to each other.

                                       22
<PAGE>
No interest, or sum of money in lieu of interest,  will be payable in respect of
any dividend  payment or payments on Preferred Stock of such series which may be
in arrears.

     Except as provided in the immediately  preceding  paragraph,  unless (i) if
such  series of  Preferred  Stock has a  cumulative  dividend,  full  cumulative
dividends on the Preferred  Stock of such series have been or  contemporaneously
are declared and paid or declared and a sum sufficient  for the payment  thereof
set  apart  for  payment  for all past  dividend  periods  and the then  current
dividend  period,  and (ii) if such  series of  Preferred  Stock does not have a
cumulative  dividend,  full dividends on the Preferred Stock of such series have
been or contemporaneously are declared and paid or declared and a sum sufficient
for the payment  thereof set apart for  payment  for the then  current  dividend
period,  no dividends (other than in Common Stock or other capital stock ranking
junior  to  the  Preferred  Stock  of  such  series  as to  dividends  and  upon
liquidation)  will be  declared  or paid  or set  aside  for  payment  or  other
distribution  upon the Common  Stock,  or any other capital stock of the Company
ranking  junior to or on a parity with the Preferred  Stock of such series as to
dividends or upon  liquidation,  nor will any Common Stock, or any other capital
stock of the Company  ranking junior to or on a parity with the Preferred  Stock
of such series as to dividends  or upon  liquidation  be redeemed,  purchased or
otherwise  acquired  for any  consideration  (or any  moneys  be paid to or made
available  for a  sinking  fund for the  redemption  of any such  stock)  by the
Company  (except by  conversion  into or exchange for other capital stock of the
Company ranking junior to the Preferred Stock of such series as to dividends and
upon liquidation).

     If for any taxable year,  the Company elects to designate as 'capital gains
dividends'  (as defined in Section 857 of the Code) any  portion  (the  'Capital
Gains  Amount') of the  dividends  (within the meaning of the Code) paid or made
available  for the year to holders of all  classes of capital  stock (the 'Total
Dividends'), then the portion of the Capital Gains Amount that will be allocable
to the holders of shares of  Preferred  Stock will be the Capital  Gains  Amount
multiplied by a fraction,  the  numerator of which shall be the total  dividends
(within the meaning of the Code) paid or made available to the holders of shares
of Preferred  Stock for the year and the denominator of which shall be the Total
Dividends.

REDEMPTION

     If so provided in the applicable Prospectus Supplement, the Preferred Stock
will be subject  to  mandatory  redemption  or  redemption  at the option of the
Company,  in whole or in part, in each case upon the terms,  at the times and at
the redemption prices set forth in such Prospectus Supplement.

     The Prospectus  Supplement  relating to a series of Preferred Stock that is
subject  to  mandatory  redemption  will  specify  the  number of shares of such
Preferred  Stock that will be redeemed  by the  Company in each year  commencing
after a date to be specified,  at a redemption  price per share to be specified,
together with an amount equal to all accrued and unpaid dividends thereon (which
will not, if such Preferred Stock does not have a cumulative  dividend,  include
any accumulation in respect of unpaid  dividends for prior dividend  periods) to
the date of  redemption.  The  redemption  price may be payable in cash or other
property,  as  specified  in  the  applicable  Prospectus  Supplement.   If  the
redemption  price for Preferred Stock of any series is payable only from the net
proceeds of the  issuance  of capital  stock of the  Company,  the terms of such
Preferred  Stock may  provide  that,  if no such  capital  stock shall have been
issued or to the extent the net proceeds from any issuance are  insufficient  to
pay in full the aggregate  redemption  price then due, such Preferred Stock will
automatically and mandatorily be converted into the applicable  capital stock of
the Company  pursuant  to  conversion  provisions  specified  in the  applicable
Prospectus Supplement.

     Notwithstanding the foregoing, unless (i) if such series of Preferred Stock
has a cumulative  dividend,  full cumulative dividends on all Preferred Stock of
any  series  shall  have  been or  contemporaneously  are  declared  and paid or
declared and a sum sufficient for the payment  thereof set apart for payment for
all past  dividend  periods  and the  current  dividend  period and (ii) if such
series of Preferred Stock does not have a cumulative dividend, full dividends of
the Preferred  Stock of any series have been or  contemporaneously  are declared
and paid or declared and a sum sufficient for the payment  thereof set apart for
payment for the then current dividend period, no Preferred Stock of any

                                       23
<PAGE>
series shall be redeemed unless all  outstanding  Preferred Stock of such series
are simultaneously  redeemed;  provided,  however,  that the foregoing shall not
prevent  the  purchase  or  acquisition  of  Preferred  Stock of such  series to
preserve  the REIT  status of the  Company or pursuant to a purchase or exchange
offer made on the same terms to holders of all  outstanding  Preferred  Stock of
such  series.  In addition,  unless (i) if such series of Preferred  Stock has a
cumulative dividend,  full cumulative dividends on all outstanding shares of any
series of Preferred Stock have been or  contemporaneously  are declared and paid
or declared and a sum sufficient  for the payment  thereof set apart for payment
for all past dividends periods and the then current dividend period, and (ii) if
such  series  of  Preferred  Stock  does not have a  cumulative  dividend,  full
dividends on the  Preferred  Stock of any series have been or  contemporaneously
are declared and paid or declared and a sum sufficient  for the payment  thereof
set apart for payment for the then current dividend period, the Company will not
purchase or otherwise acquire directly or indirectly any Preferred Stock of such
series  (except by conversion  into or exchange for capital stock of the Company
ranking  junior to the  Preferred  Stock of such series as to dividends and upon
liquidation);  provided,  however,  that  the  foregoing  will not  prevent  the
purchase or acquisition  of Preferred  Stock of such series to preserve the REIT
status of the Company or  pursuant  to a purchase or exchange  offer made on the
same terms to holders of all outstanding Preferred Stock of such series.

     If fewer  than all of the  outstanding  shares  of  Preferred  Stock of any
series  are to be  redeemed,  the  number  of  shares  to be  redeemed  will  be
determined  by the Company  and such  shares may be  redeemed  pro rata from the
holders of record of such shares in proportion to the number of such shares held
or for which  redemption is requested by such holder (with  adjustments to avoid
redemption  of  fractional  shares)  or by lot  in a  manner  determined  by the
Company.

     Notice of  redemption  will be mailed at least 30 days but not more than 60
days before the redemption  date to each holder of record of Preferred  Stock of
any series to be redeemed at the address  shown on the stock  transfer  books of
the Company. Each notice will state: (i) the redemption date; (ii) the number of
shares and series of Preferred Stock to be redeemed; (iii) the redemption price;
(iv) the place or places where  certificates  for such Preferred Stock are to be
surrendered  for payment of the  redemption  price;  (v) that  dividends  on the
shares to be redeemed will cease to accrue on such redemption date; and (vi) the
date upon which the holder's  conversion rights, if any, as to such shares shall
terminate.  If fewer  than all of the  Preferred  Stock of any  series are to be
redeemed,  the notice  mailed to each such holder  thereof will also specify the
number of shares of Preferred  Stock to be redeemed  from each such  holder.  If
notice of  redemption  of any  Preferred  Stock has been  given and if the funds
necessary  for such  redemption  have been set aside by the Company in trust for
the benefit of the holders of any Preferred Stock so called for redemption, then
from and  after  the  redemption  date  dividends  will  cease to accrue on such
Preferred  Stock,  and all rights of the holders of such shares will  terminate,
except the right to receive the redemption price.

LIQUIDATION PREFERENCE

     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the affairs of the Company,  then, before any distribution or payment is made to
the holders of any Common Stock or any other class or series of capital stock of
the Company ranking junior to the Preferred Stock in the  distribution of assets
upon any liquidation,  dissolution or winding up of the Company,  the holders of
each series of Preferred Stock shall be entitled to receive out of assets of the
Company  legally   available  for   distribution  to  stockholders   liquidating
distributions  in the amount of the liquidation  preference per share (set forth
in the applicable Prospectus Supplement),  plus an amount equal to all dividends
accrued and unpaid thereon (which will not include any  accumulation  in respect
of unpaid  dividends for prior dividend periods if such Preferred Stock does not
have a cumulative dividend). After payment of the full amount of the liquidating
distributions  to which they are entitled,  the holders of Preferred  Stock will
have no right or claim to any of the  remaining  assets of the  Company.  In the
event that, upon any such voluntary or involuntary  liquidation,  dissolution or
winding up, the  available  assets of the Company  are  insufficient  to pay the
amount of the liquidating  distributions on all outstanding  Preferred Stock and
the  corresponding  amounts  payable on all shares of other classes or series of
capital stock of the Company ranking on a parity with the Preferred Stock in the
distribution of assets, then the holders of

                                       24
<PAGE>
the Preferred  Stock and all other such classes or series of capital stock shall
share  ratably  in any such  distribution  of assets in  proportion  to the full
liquidating   distributions  to  which  they  would  otherwise  be  respectively
entitled.

     If liquidating distributions shall have been made in full to all holders of
Preferred Stock,  the remaining assets of the Company will be distributed  among
the holders of any other classes or series of capital  stock  ranking  junior to
the Preferred Stock upon  liquidation,  dissolution or winding up,  according to
their  respective  rights and  preferences  and in each case  according to their
respective number of shares.  For such purposes,  the consolidation or merger of
the Company with or into any other  corporation,  trust or entity,  or the sale,
lease or conveyance of all or  substantially  all of the property or business of
the Company,  will not be deemed to  constitute a  liquidation,  dissolution  or
winding up of the Company.

VOTING RIGHTS

     Holders of Preferred  Stock will not have any voting rights,  except as set
forth below or as otherwise from time to time required by law or as indicated in
the applicable Prospectus Supplement.

     Whenever  dividends on any  Preferred  Stock shall be in arrears for six or
more consecutive  quarterly periods, the holders of such Preferred Stock (voting
separately  as a class with all other series of Preferred  Stock upon which like
voting rights have been conferred and are exercisable)  will be entitled to vote
for the election of two additional directors of the Company at a special meeting
called by the holders of record of at least ten  percent  (10%) of any series of
Preferred Stock so in arrears (unless such request is received less than 90 days
before  the  date  fixed  for  the  next  annual  or  special   meeting  of  the
shareholders)  or at the  next  annual  meeting  of  stockholders,  and at  each
subsequent  annual  meeting  until (i) if such series of  Preferred  Stock has a
cumulative dividend, all dividends accumulated on such shares of Preferred Stock
for the past dividend  periods and the then current  dividend  period shall have
been fully paid or declared  and a sum  sufficient  for the payment  thereof set
aside  for  payment  or (ii) if such  series  of  Preferred  Stock do not have a
cumulative dividend,  four consecutive quarterly dividends shall have been fully
paid or declared  and a sum  sufficient  for the  payment  thereof set aside for
payment. In such case, the entire Board will be increased by two directors.

     Unless provided otherwise for any series of Preferred Stock, so long as any
shares of Preferred Stock remain outstanding,  the Company will not, without the
affirmative vote or consent of the holders of at least two-thirds of each series
of shares of  Preferred  Stock  outstanding  at the time,  given in person or by
proxy,  either in writing or at a meeting  (such series  voting  separately as a
class), (i) authorize or create, or increase the authorized or issued amount of,
any class or series of capital  stock  ranking prior to such series of Preferred
Stock with  respect to the payment of dividends  or the  distribution  of assets
upon liquidation, dissolution or winding up or reclassify any authorized capital
stock of the  Company  into  such  shares,  or  create,  authorize  or issue any
obligation or security  convertible into or evidencing the right to purchase any
such shares,  or (ii) amend,  alter or repeal the  provisions  of the  Company's
Articles  of  Incorporation  or the  Designating  Amendment  for such  series of
Preferred Stock, whether by merger,  consolidation or otherwise (an 'Event'), so
as to materially and adversely affect any right, preference, privilege or voting
power of such  series  of  Preferred  Stock or the  holders  thereof;  provided,
however, with respect to the occurrence of any of the Events set forth in clause
(ii) above, so long as the shares of Preferred Stock remain outstanding with the
terms thereof materially unchanged, taking into account that upon the occurrence
of an Event the Company may not be the surviving  entity,  the occurrence of any
such Event will not be deemed to materially  and  adversely  affect such rights,
preferences,  privileges  or voting  power of  holders  of  Preferred  Stock and
provided further that (x) any increase in the amount of the authorized Preferred
Stock or the creation or issuance of any other series of Preferred Stock, or (y)
any  increase  in the amount of  authorized  shares of such  series or any other
series of  Preferred  Stock,  in each case ranking on a parity with or junior to
the  Preferred  Stock of such series with respect to payment of dividends or the
distribution of assets upon liquidation,  dissolution or winding up, will not be
deemed to materially and adversely affect such rights,  preferences,  privileges
or voting powers.

                                       25
<PAGE>
     The foregoing voting  provisions will not apply if, at or prior to the time
when the act with respect to which such vote would  otherwise be required  shall
be effected, all outstanding shares of Preferred Stock of such series shall have
been  redeemed or called for  redemption  and  sufficient  funds shall have been
deposited in trust to effect such redemption.

CONVERSION RIGHTS

     The terms and conditions,  if any, upon which any series of Preferred Stock
is convertible into Common Stock will be set forth in the applicable  Prospectus
Supplement  relating  thereto.  Such terms will  include the number of shares of
Common Stock into which the  Preferred  Stock are  convertible,  the  conversion
price (or manner of calculation thereof),  the conversion period,  provisions as
to  whether  conversion  will be at the option of the  holders of the  Preferred
Stock or the Company, the events requiring an adjustment of the conversion price
and  provisions  affecting  conversion  in the event of the  redemption  of such
series of Preferred Stock.

RESTRICTIONS ON OWNERSHIP

     As discussed  below under  'Description  of Common  Stock--Restrictions  on
Transfer--Ownership  Limits,'  for the  Company  to  qualify as a REIT under the
Code, no more than 50% in value of its  outstanding  capital stock may be owned,
directly or indirectly,  by five or fewer  'individuals' (as defined in the Code
to include certain  entities) during the last half of a taxable year (other than
the first year) or during a  proportionate  part of a shorter  taxable  year. To
assist the Company in meeting this  requirement,  the Articles of  Incorporation
provide that no holder of Preferred Stock may own, or be deemed to own by virtue
of  certain  attribution  provisions  of the Code,  more than 5% of any class or
series of  Preferred  Stock  and/or  more than 5% of the issued and  outstanding
shares of Common Stock,  subject to certain exceptions specified in the Articles
of   Incorporation.   See   'Description   of  Common   Stock--Restrictions   on
Transfer--Ownership Limits.'

REGISTRAR AND TRANSFER AGENT

     The Registrar and Transfer Agent for the Preferred  Stock will be set forth
in the applicable Prospectus Supplement.

     The Company is authorized to issue  90,000,000  shares of Common Stock. The
outstanding  Common  Stock  entitles  the  holder  to one  vote  on all  matters
presented to stockholders for a vote. Holders of Common Stock have no preemptive
rights.  At September  30, 1997,  there were  58,168,602  shares of Common Stock
outstanding.

     Shares of Common Stock currently  outstanding are listed for trading on the
New York Stock Exchange (the 'NYSE'). The Company will apply to the NYSE to list
the additional  Common Stock to be sold pursuant to any  Prospectus  Supplement,
and the Company anticipates that such shares will be so listed.

     Subject  to such  preferential  rights  as may be  granted  by the Board in
connection with the future issuance of Preferred Stock,  holders of Common Stock
are entitled to one vote per share on all matters to be voted on by stockholders
and are  entitled to receive  ratably  such  dividends as may be declared on the
Common  Stock by the  Board  in its  discretion  from  funds  legally  available
therefor.  In the event of the  liquidation,  dissolution  or  winding up of the
Company,  holders of Common  Stock are  entitled to share  ratably in all assets
remaining  after payment of all debts and other  liabilities and any liquidation
preference  of the holders of Preferred  Stock.  Holders of Common Stock have no
subscription, redemption, conversion or preemptive rights. Matters submitted for
stockholder approval generally require a majority vote of the shares present and
voting thereon.

ADVANCE NOTICE OF DIRECTOR NOMINATIONS AND NEW BUSINESS

     The Bylaws of the Company  provide that,  with respect to an annual meeting
of  stockholders,  the proposal of business to be considered by stockholders may
be made only (i) by or at the  direction  of the Board or (ii) by a  stockholder
who is entitled to vote at the  meeting  and who has  complied  with the advance
notice  procedures  set forth in the Bylaws.  In  addition,  with respect to any
meeting of stockholders, nominations of persons for election to the Board may be
made only (i) by or at the direction of the Board or (ii) by any  stockholder of
the Company who is  entitled  to vote at the meeting and has  complied  with the
advance notice provisions set forth in the Bylaws.

RESTRICTIONS ON TRANSFER

     Ownership Limits. The Company's  Articles of Incorporation  contain certain
restrictions   on  the  number  of  shares  of  Common  Stock  that   individual
shareholders  may own.  For the Company to qualify as a REIT under the Code,  no
more than 50% in value of its outstanding  capital stock may be owned,  directly
or indirectly, by five or fewer 'individuals' (as defined in the Code to include
certain  entities)  during the last half of a taxable year (other than the first
year) or during a  proportionate  part of a shorter  taxable  year.  The capital
stock also must be beneficially owned by 100 or more persons during at least 335
days of a taxable year or during a proportionate part of a shorter taxable year.
Because  the  Company  intends to  maintain  its  qualification  as a REIT,  the
Company's  Articles  of  Incorporation   contain  certain  restrictions  on  the
ownership and transfer of capital  stock,  including  Common Stock,  intended to
ensure compliance with these requirements.

     Subject to certain  exceptions  specified in the Articles of Incorporation,
no  holder  may own,  or be  deemed  to own by  virtue  of  certain  attribution
provisions of the Code, more than (A) 5% of the issued and outstanding shares of
Common Stock (the 'Common Stock Ownership Limit') and/or (B) more than 5% of any
class or series of Preferred  Stock.  (This  limit,  in addition to the Existing
Holder Limit, the Special Shareholder Limit, and the Non U.S. Shareholder Limit,
all as defined  below,  are referred to  collectively  herein as the  'Ownership
Limits.')  Existing  Holders,  including Clark Enterprises Inc., The Oliver Carr
Company,  Oliver T. Carr, Jr., and A. James Clark, are not subject to the Common
Stock Ownership  Limit,  but they are subject to special  ownership  limitations
(the 'Existing Holder Limit').  Furthermore,  SC-USREALTY and its affiliates are
not subject to the Common Stock  Ownership  Limit,  but are subject to a special
ownership limit of 45% of the outstanding  shares of Common Stock and 45% of the
outstanding  shares of each class or series of  preferred  stock of the  Company
(the 'Special Shareholder Limit').  Furthermore, all holders are prohibited from
acquiring  any capital  stock if such  acquisition  would cause five  beneficial
owners of capital stock to  beneficially  own in the aggregate  more than 50% in
value of the outstanding capital stock.

     In addition to the above  restrictions  on  ownership  of shares of capital
stock  of the  Company,  in order to  assist  the  Company  in  qualifying  as a
'domestically  controlled  REIT,' the Articles of Incorporation  contain certain
provisions  preventing any Non-U.S.  Shareholder  (as defined below) (other than
SC-USREALTY  and  its  affiliates)  from  acquiring  additional  shares  of  the
Company's capital stock if, as a result of such  acquisition,  the Company would
fail to qualify as a  'domestically  controlled  REIT'  (computed  assuming that
SC-USREALTY owns the maximum  percentage of the Company's  capital stock that it
is  permitted  to own  under  the  Special  Shareholder  Limit)  (the  'Non-U.S.
Shareholder  Limit'). A Non-U.S.  Shareholder is a nonresident alien individual,
foreign corporation,  foreign partnership and any other foreign shareholder. For
a discussion of the taxation of a Non-U.S.  Shareholder and the requirements for
the Company to qualify as a 'domestically  controlled REIT,' see 'Federal Income
Tax  Considerations--Taxation  of Holders of Common  Stock--Taxation of Non-U.S.
Shareholders.'  The  Company  is  unlikely  to be able to  advise a  prospective
Non-U.S.  Shareholder  that its purchase of any shares of the Company's  capital
stock would not violate this  prohibition,  thereby  subjecting such prospective
Non-U.S. Shareholder to the adverse consequences described under '--Violation of
Ownership  Limits' below.  Accordingly,  an acquisition of the Company's capital
stock would not likely be a suitable investment for Non-U.S.  Shareholders other
than SC-USREALTY.

     The Board may increase the Ownership  Limits from time to time, but may not
do so to the extent that, after giving effect to such increase,  five beneficial
owners of shares of capital stock could

                                       27
<PAGE>
beneficially  own in the aggregate more than 49.5% of the Company's  outstanding
shares of  capital  stock.  The  Board,  in its sole  discretion,  may waive the
Ownership  Limits with respect to a holder if such holder's  ownership  will not
then or in the future jeopardize the Company's status as a REIT.

     Violation of Ownership Limits. The Articles of Incorporation  provide that,
if any holder of capital stock of the Company  purports to transfer  shares to a
person or there is a change in the capital  structure  of the Company and either
the  transfer  or the change in capital  structure  would  result in the Company
failing  to  qualify  as a REIT,  or such  transfer  or the  change  in  capital
structure  would cause the transferee to hold shares in excess of the applicable
Ownership Limit  (including the Non-U.S.  Shareholder  Limit),  then the capital
stock being  transferred (or in the case of an event other than a transfer,  the
capital  stock  beneficially  owned)  that  would  cause  one  or  more  of  the
restrictions  on  ownership  or transfer to be  violated  will be  automatically
transferred to a trust for the benefit of a designated  charitable  beneficiary.
The purported transferee of such shares shall have no right to receive dividends
or other  distributions  with  respect to such shares and shall have no right to
vote such shares.  Any dividends or other  distributions  paid to such purported
transferee  prior to the  discovery  by the  Company  that the shares  have been
transferred to a trust shall be paid upon demand to the trustee of the trust for
the benefit of the  charitable  beneficiary.  The trustee of the trust will have
all rights to  dividends  with  respect  to the shares of capital  stock held in
trust,  which  rights  will  be  exercised  for  the  exclusive  benefit  of the
charitable beneficiary.  Any dividends or distributions paid over to the trustee
will  be  held in  trust  for the  charitable  beneficiary.  The  trustee  shall
designate a  transferee  of such stock so long as such shares of stock would not
violate the Ownership  Limitations in the hands of such  designated  transferee.
Upon the sale of such shares, the purported  transferee shall receive the lesser
of (A) (i) the price per share such  purported  transferee  paid for the capital
stock in the  purported  transfer  that  resulted  in the  transfer of shares of
capital stock to the trust, or (ii) if the transfer or other event that resulted
in the transfer of shares of capital stock to the trust was not a transaction in
which the purported record transferee of shares of capital stock gave full value
for such shares,  a price per share equal to the market price on the date of the
purported transfer or other event that resulted in the transfer of the shares to
the trust,  and (B) the price per share received by the trustee from the sale or
disposition of the shares held in the trust.

     All certificates  representing Common Stock will bear a legend referring to
the restrictions described above.

     Every  owner of more than 5% (or such lower  percentage  as required by the
Code or regulations  thereunder) of the issued and outstanding  shares of Common
Stock must file a written  notice with the Company  containing  the  information
specified in the  Articles of  Incorporation  no later than  December 31 of each
year. In addition, each stockholder shall upon demand be required to disclose to
the Company in writing such information as the Company may request in good faith
in order to determine the Company's status as a REIT.

REGISTRAR AND TRANSFER AGENT

     The Registrar and Transfer Agent for the Common Stock is BankBoston, N.A.

                      DESCRIPTION OF COMMON STOCK WARRANTS

     The Company may issue  Common  Stock  Warrants  for the  purchase of Common
Stock.  Common Stock Warrants may be issued  independently  or together with any
other Securities offered by any Prospectus  Supplement and may be attached to or
separate  from such  Securities.  Each series of Common Stock  Warrants  will be
issued under a separate warrant  agreement  (each, a 'Warrant  Agreement') to be
entered into between the Company and a warrant agent specified in the applicable
Prospectus  Supplement (the 'Warrant Agent').  The Warrant Agent will act solely
as an agent of the Company in connection  with the Common Stock Warrants of such
series and will not assume any obligation or relationship of agency or trust for
or with any holders or beneficial owners of Common Stock Warrants. The following
sets forth  certain  general terms and  provisions of the Common Stock  Warrants
offered  hereby.  Further terms of the Common Stock  Warrants and the applicable
Warrant Agreements will be set forth in the applicable Prospectus Supplement.

                                       28
<PAGE>
     The applicable  Prospectus Supplement will describe the terms of the Common
Stock  Warrants  in  respect  of  which  this  Prospectus  is  being  delivered,
including,  where applicable,  the following: (1) the title of such Common Stock
Warrants;  (2) the aggregate number of such Common Stock Warrants; (3) the price
or  prices  at  which  such  Common  Stock  Warrants  will  be  issued;  (4) the
designation,  number and terms of the shares of Common  Stock  purchasable  upon
exercise of such Common Stock  Warrants;  (5) the  designation  and terms of the
other  Securities  offered  thereby  with which such Common  Stock  Warrants are

Security offered  thereby;  (6) the date, if any, on and after which such Common
Stock Warrants and the related Common Stock will be separately transferable; (7)
the price at which each of the shares of Common Stock  purchasable upon exercise
of such Common Stock Warrants may be purchased;  (8) the date on which the right
to exercise such Common Stock Warrants shall commence and the date on which such
right  shall  expire;  (9) the minimum or maximum  number of such  Common  Stock
Warrants which may be exercised at any one time; (10)  information  with respect
to book entry  procedures,  if any; (11) a discussion of certain  federal income
tax  considerations;  and (12) any other  terms of such Common  Stock  Warrants,
including  terms,  procedures  and  limitations  relating  to the  exchange  and
exercise of such Common Stock Warrants.

                        DESCRIPTION OF DEPOSITARY SHARES

GENERAL

     The Company  may issue  receipts  ('Depositary  Receipts')  for  Depositary
Shares,  each of which will  represent  a  fractional  interest  of a share of a
particular series of Preferred Stock, as specified in the applicable  Prospectus
Supplement.  Shares of Preferred Stock of each series  represented by Depositary
Shares will be deposited under a separate  deposit  agreement  (each, a 'Deposit
Agreement') among the Company,  the depositary named therein (a 'Preferred Stock
Depositary')  and the  holders  from  time to time of the  Depositary  Receipts.
Subject  to the  terms of the  applicable  Deposit  Agreement,  each  owner of a
Depositary Receipt will be entitled, in proportion to the fractional interest of
a share of a particular  series of Preferred Stock represented by the Depositary
Shares evidenced by such Depositary  Receipt,  to all the rights and preferences
of  the  Preferred  Stock  represented  by  such  Depositary  Shares  (including
dividend, voting, conversion, redemption and liquidation rights).

     The  Depositary  Shares will be evidenced  by  Depositary  Receipts  issued
pursuant to the applicable Deposit Agreement. Immediately following the issuance
and  delivery  of the  Preferred  Stock  by the  Company  to a  Preferred  Stock
Depositary,  the Company will cause such Preferred Stock Depositary to issue, on
behalf of the Company, the Depositary Receipts. Copies of the applicable form of
Deposit  Agreement and Depositary  Receipt may be obtained from the Company upon
request,  and the statements made hereunder  relating to Deposit  Agreements and
the  Depositary  Receipts  to be issued  thereunder  are  summaries  of  certain
anticipated provisions thereof and do not purport to be complete and are subject
to, and qualified in their  entirety by reference  to, all of the  provisions of
the applicable Deposit Agreement and related Depositary Receipts.

DIVIDENDS AND OTHER DISTRIBUTIONS

     A  Preferred  Stock  Depositary  will be required  to  distribute  all cash
dividends  or other cash  distributions  received  in respect of the  applicable
Preferred  Stock to the record  holders of Depositary  Receipts  evidencing  the
related  Depositary  Shares  in  proportion  to the  number  of such  Depositary
Receipts  owned by such holders,  subject to certain  obligations  of holders to
file proofs,  certificates and other  information and to pay certain charges and
expenses to such Preferred Stock Depositary.

     In the  event of a  distribution  other  than in cash,  a  Preferred  Stock
Depositary will be required to distribute  property received by it to the record
holders of Depositary Receipts entitled thereto,  subject to certain obligations
of holders to file proofs, certificates and other information and to pay certain
charges and expenses to such Preferred Stock  Depositary,  unless such Preferred
Stock Depositary  determines that it is not feasible to make such  distribution,
in which case such  Preferred  Stock  Depositary  may,  with the approval of the
Company,  sell such property and  distribute  the net proceeds from such sale to
such holders.

                                       29
<PAGE>
     No  distribution  will be made in  respect of any  Depositary  Share to the
extent  that it  represents  any  Preferred  Stock which has been  converted  or
exchanged before the record date for such distribution.

WITHDRAWAL OF STOCK

     Upon surrender of the Depositary  Receipts at the corporate trust office of
the applicable  Preferred Stock Depositary (unless the related Depositary Shares
have  previously  been called for redemption or converted),  the holders thereof
will be  entitled  to delivery  at such  office,  to or upon each such  holder's
order, of the number of whole or fractional  shares of the applicable  Preferred
Stock and any  money or other  property  represented  by the  Depositary  Shares
evidenced by such Depositary  Receipts.  Holders of Depositary  Receipts will be
entitled to receive whole or fractional shares of the related Preferred Stock on
the basis of the proportion of Preferred  Stock  represented by each  Depositary
Share as specified in the applicable Prospectus Supplement,  but holders of such
shares of Preferred Stock will not thereafter be entitled to receive  Depositary
Shares therefor.  If the Depositary  Receipts delivered by the holder evidence a
number  of  Depositary  Shares in excess  of the  number  of  Depositary  Shares
representing  the  number of  shares of  Preferred  Stock to be  withdrawn,  the
applicable Preferred Stock Depositary will be required to deliver to such holder
at the same time a new  Depositary  Receipt  evidencing  such  excess  number of
Depositary Shares.

REDEMPTION OF DEPOSITARY SHARES

     Whenever the Company  redeems shares of Preferred Stock held by a Preferred
Stock Depositary,  such Preferred Stock Depositary will be required to redeem as
of the same redemption date the number of Depositary Shares  representing shares
of the Preferred Stock so redeemed, provided the Company shall have paid in full
to such Preferred Stock  Depositary the redemption  price of the Preferred Stock
to be redeemed plus an amount equal to any accrued and unpaid dividends  thereon
to the date fixed for redemption. The redemption price per Depositary Share will
be equal to the  redemption  price and any other  amounts per share payable with
respect to the Preferred  Stock. If fewer than all the Depositary  Shares are to
be redeemed,  the Depositary Shares to be redeemed will be selected pro rata (as
nearly as may be practicable without creating  fractional  Depositary Shares) or
by any other equitable method  determined by the Company that preserves the REIT
status of the Company.

     From and after the date fixed for  redemption,  all dividends in respect of
the shares of Preferred Stock so called for redemption will cease to accrue, the
Depositary  Shares  so  called  for  redemption  will no  longer be deemed to be
outstanding and all rights of the holders of the Depositary  Receipts evidencing
the Depositary  Shares so called for redemption will cease,  except the right to
receive any moneys payable upon such  redemption and any money or other property
to which  the  holders  of such  Depositary  Receipts  were  entitled  upon such
redemption upon surrender thereof to the applicable Preferred Stock Depositary.

VOTING OF THE PREFERRED STOCK

     Upon  receipt  of  notice  of any  meeting  at  which  the  holders  of the
applicable  Preferred Stock are entitled to vote, a Preferred  Stock  Depositary
will be required to mail the information  contained in such notice of meeting to
the record holders of the Depositary  Receipts  evidencing the Depositary Shares
which represent such Preferred Stock. Each record holder of Depositary  Receipts
evidencing  Depositary Shares on the record date (which will be the same date as
the record date for the  Preferred  Stock)  will be  entitled  to instruct  such
Preferred Stock Depositary as to the exercise of the voting rights pertaining to
the amount of Preferred Stock  represented by such holder's  Depositary  Shares.
Such Preferred Stock Depositary will be required to vote the amount of Preferred
Stock   represented  by  such   Depositary   Shares  in  accordance   with  such
instructions, and the Company will agree to take all reasonable action which may
be deemed  necessary by such Preferred Stock  Depositary in order to enable such
Preferred  Stock  Depositary to do so. Such Preferred  Stock  Depositary will be
required to abstain from voting the amount of  Preferred  Stock  represented  by
such Depositary  Shares to the extent it does not receive specific  instructions
from the holders of Depositary  Receipts  evidencing such Depositary  Shares.  A
Preferred Stock  Depositary will not be responsible for any failure to carry out
any  instruction  to vote, or for the manner or effect of any such vote made, as
long as any such action or non-

                                       30
<PAGE>
action  is in good  faith  and  does  not  result  from  negligence  or  willful
misconduct of such Preferred Stock Depositary.

LIQUIDATION PREFERENCE

     In the event of the liquidation,  dissolution or winding up of the Company,
whether voluntary or involuntary, the holders of each Depositary Receipt will be
entitled to the fraction of the  liquidation  preference  accorded each share of
Preferred Stock represented by the Depositary Share evidenced by such Depositary
Receipt, as set forth in the applicable Prospectus Supplement.

CONVERSION OF PREFERRED STOCK

     The Depositary  Shares,  as such, will not be convertible into Common Stock
or any  other  securities  or  property  of  the  Company.  Nevertheless,  if so
specified in the  applicable  Prospectus  Supplement  relating to an offering of
Depositary Shares, the Depositary Receipts may be surrendered by holders thereof
to the applicable  Preferred Stock Depositary with written  instructions to such
Preferred  Stock  Depositary to instruct the Company to cause  conversion of the
Preferred  Stock   represented  by  the  Depositary  Shares  evidenced  by  such
Depositary Receipts into whole shares of Common Stock, other shares of Preferred
Stock of the Company or other  shares of stock,  and the Company will agree that
upon receipt of such instructions and any amounts payable in respect thereof, it
will  cause  the  conversion  thereof  utilizing  the same  procedures  as those
provided  for  delivery of  Preferred  Stock to effect such  conversion.  If the
Depositary Shares evidenced by a Depositary  Receipt are to be converted in part
only, a new  Depositary  Receipt or Receipts  will be issued for any  Depositary
Shares not to be converted.  No fractional shares of Common Stock will be issued
upon conversion,  and if such conversion will result in a fractional share being
issued,  an amount will be paid in cash by the Company equal to the value of the
fractional interest based upon the closing price of the Common Stock on the last
business day prior to the conversion.

AMENDMENT AND TERMINATION OF A DEPOSIT AGREEMENT

     Any form of  Depositary  Receipt  evidencing  Depositary  Shares which will
represent  Preferred  Stock and any  provision  of a Deposit  Agreement  will be
permitted  at any time to be amended by  agreement  between  the Company and the
applicable  Preferred Stock Depositary.  However,  any amendment that materially
and adversely  alters the rights of the holders of  Depositary  Receipts or that
would be materially  and adversely  inconsistent  with the rights granted to the
holders  of the  related  Preferred  Stock  will not be  effective  unless  such
amendment  has been approved by the existing  holders of at least  two-thirds of
the applicable Depositary Shares evidenced by the applicable Depositary Receipts
then  outstanding.  No  amendment  shall  impair the  right,  subject to certain
anticipated  exceptions in the Deposit Agreements,  of any holders of Depositary
Receipts to surrender any Depositary Receipt with instructions to deliver to the
holder the related  Preferred  Stock and all money and other  property,  if any,
represented  thereby,  except in order to comply  with law.  Every  holder of an
outstanding  Depositary Receipt at the time any such amendment becomes effective
shall be deemed, by continuing to hold such Depositary  Receipt,  to consent and
agree to such amendment and to be bound by the applicable  Deposit  Agreement as
amended thereby.

     A Deposit  Agreement will be permitted to be terminated by the Company upon
not less than 30 days' prior written  notice to the applicable  Preferred  Stock
Depositary if (i) such termination is necessary to preserve the Company's status
as a REIT or (ii) a majority of each series of Preferred  Stock affected by such
termination  consents  to  such  termination,  whereupon  such  Preferred  Stock
Depositary  will be  required  to deliver or make  available  to each  holder of
Depositary  Receipts,  upon  surrender of the  Depositary  Receipts held by such
holder,  such number of whole or  fractional  shares of  Preferred  Stock as are
represented  by the  Depositary  Shares  evidenced by such  Depositary  Receipts
together with any other property held by such Preferred  Stock  Depositary  with
respect to such  Depositary  Receipts.  The Company will agree that if a Deposit
Agreement is  terminated to preserve the  Company's  status as a REIT,  then the
Company  will use its best  efforts  to list the  Preferred  Stock  issued  upon
surrender of the related Depositary Shares on a national securities exchange. In
addition,   a  Deposit  Agreement  will  automatically   terminate  if  (i)  all
outstanding  Depositary Shares  thereunder shall have been redeemed,  (ii) there
shall have been a final  distribution in respect of the related  Preferred Stock
in connection with any liquidation, dissolution or winding up of the Company and
such distribution

                                       31
<PAGE>
shall have been distributed to the holders of Depositary Receipts evidencing the
Depositary  Shares  representing such Preferred Stock or (iii) each share of the
related  Preferred Stock shall have been converted into stock of the Company not
so represented by Depositary Shares.

CHARGES OF A PREFERRED STOCK DEPOSITARY

     The Company will pay all transfer and other taxes and governmental  charges
arising  solely from the  existence of a Deposit  Agreement.  In  addition,  the
Company  will pay the fees and  expenses  of a  Preferred  Stock  Depositary  in
connection  with  the  performance  of its  duties  under a  Deposit  Agreement.
However,  holders of  Depositary  Receipts  will pay the fees and  expenses of a
Preferred  Stock  Depositary  for any  duties  requested  by such  holders to be
performed  which are outside of those  expressly  provided for in the applicable
Deposit Agreement.

RESIGNATION AND REMOVAL OF DEPOSITARY

     A Preferred  Stock  Depositary  will be  permitted to resign at any time by
delivering to the Company  notice of its election to do so, and the Company will
be  permitted  at any time to  remove a  Preferred  Stock  Depositary,  any such
resignation  or removal  to take  effect  upon the  appointment  of a  successor
Preferred  Stock  Depositary.  A successor  Preferred  Stock  Depositary will be
required  to be  appointed  within  60 days  after  delivery  of the  notice  of
resignation or removal and will be required to be a bank or trust company having
its  principal  office in the United  States and having a combined  capital  and
surplus of at least $50,000,000.

MISCELLANEOUS

     A  Preferred  Stock  Depositary  will be  required to forward to holders of
Depositary  Receipts any reports and  communications  from the Company which are
received  by  such  Preferred  Stock  Depositary  with  respect  to the  related
Preferred Stock.

     Neither a Preferred  Stock  Depositary nor the Company will be liable if it
is prevented from or delayed in, by law or any circumstances beyond its control,
performing its  obligations  under a Deposit  Agreement.  The obligations of the
Company and a  Preferred  Stock  Depositary  under a Deposit  Agreement  will be
limited  to  performing  their  duties  thereunder  in good  faith  and  without
negligence  (in the case of any action or  inaction  in the voting of  Preferred
Stock  represented by the applicable  Depositary  Shares),  gross  negligence or
willful misconduct,  and neither the Company nor any applicable  Preferred Stock
Depositary  will be obligated to  prosecute  or defend any legal  proceeding  in
respect of any  Depositary  Receipts,  Depositary  Shares or shares of Preferred
Stock  represented  thereby  unless  satisfactory  indemnity is  furnished.  The
Company and any Preferred Stock  Depositary will be permitted to rely on written
advice of counsel or accountants,  or information provided by persons presenting
shares of Preferred Stock represented thereby for deposit, holders of Depositary
Receipts or other  persons  believed in good faith to be  competent to give such
information, and on documents believed in good faith to be genuine and signed by
a proper party.

     In the event a Preferred Stock Depositary shall receive conflicting claims,
requests or  instructions  from any holders of Depositary  Receipts,  on the one
hand, and the Company on the other hand, such Preferred Stock  Depositary  shall
be entitled to act on such claims,  requests or  instructions  received from the
Company.

                             BOOK-ENTRY SECURITIES

     The  Securities  may be  issued  in  whole or in part in  book-entry  form,
meaning that beneficial  owners of the Securities will not receive  certificates
representing  their ownership  interests in the Securities,  except in the event
the book-entry system for the Securities is discontinued.  If the Securities are
issued in book-entry  form, they will be issued,  the form of one or more global
securities (the 'Global Securities'), which will be deposited with, or on behalf
of, a depository  identified in the applicable Prospectus Supplement relating to
such series. Global Securities may be issued in either registered or bearer form
and in either  temporary or permanent form. The specific terms of the depository
arrangement with respect to a class or series of Securities issued in book-entry
form will be described in the applicable  Prospectus Supplement relating to such
class or series.

                       FEDERAL INCOME TAX CONSIDERATIONS

GENERAL

     The  following  discussion  summarizes  the  material  federal  income  tax
considerations   to  a  prospective   holder  of  Common  Stock.  The  following
discussion, which is not exhaustive of all possible tax considerations, does not
give a detailed  discussion of any state,  local or foreign tax  considerations.
Nor does it discuss all of the aspects of federal  income  taxation  that may be
relevant  to a  prospective  Security  holder in light of his or her  particular
circumstances  or to certain  types of  Security  holders  (including  insurance

If the Company offers one or more series of Preferred Stock,  Depositary Shares,
Common Stock Warrants or Debt Securities, then there may be tax consequences for
the holders of such  Securities  not discussed  herein.  For a discussion of any
such additional consequences, see the applicable Prospectus Supplement.

     As  discussed  below,  the  Taxpayer  Relief Act of 1997 (the  '1997  Act')
contains  certain  changes  to the REIT  qualification  requirements  and to the
taxation of REITs that may be material  to a holder of Common  Stock,  but which
will become  effective  only for the Company's  taxable  years  commencing on or
after January 1, 1998.

     As used under this heading, the term 'Company' refers solely to CarrAmerica
Realty Corporation.

     EACH  PROSPECTIVE  PURCHASER  IS ADVISED TO CONSULT WITH HIS OR HER OWN TAX
ADVISOR  REGARDING THE SPECIFIC TAX  CONSEQUENCES TO HIM OR HER OF THE PURCHASE,
OWNERSHIP AND SALE OF SECURITIES OF IN AN ENTITY ELECTING TO BE TAXED AS A REIT,

PURCHASE,  OWNERSHIP,  SALE AND ELECTION AND OF POTENTIAL  CHANGES IN APPLICABLE
TAX LAWS.

TAXATION OF THE COMPANY

     General. The Company,  which is considered a corporation for federal income
tax purposes,  has elected to be taxed as a REIT under  Sections 856 through 860
of the Code  effective  as of its taxable  year ended  December  31,  1993.  The
Company  believes  that it was  organized  and has operated in a manner so as to
qualify  for  taxation  as a REIT  under the Code,  and the  Company  intends to
continue to operate in such a manner. No assurance,  however,  can be given that
the Company has  operated in a manner so as to qualify as a REIT or that it will
continue to operate in such a manner in the future.  Qualification  and taxation
as a REIT  depends  upon the  Company's  ability to meet on a  continuing  basis
(through actual annual operating results,  distribution  levels and diversity of
stock  ownership)  the various  qualification  tests  imposed  under the Code on
REITs, some of which are summarized below.  While the Company intends to operate
so that it qualifies  as a RElT,  given the highly  complex  nature of the rules
governing  REITs,  the ongoing  importance  of factual  determinations,  and the
possibility of future changes in circumstances of the Company,  no assurance can
be given that the  Company  has  satisfied  or will  satisfy  such tests or will
continue to do so. See '--Failure to Qualify' below.

     The following is a general  summary of the Code  provisions that govern the
federal income tax treatment of a REIT and its shareholders. These provisions of
the Code are highly  technical  and  complex.  This  summary is qualified in its
entirety  by  the  applicable   Code   provisions,   Treasury   Regulations  and
administrative and judicial interpretations thereof.

     In any year in which the  Company  qualifies  for  taxation  as a REIT,  it
generally  will not be subject to federal  corporate  income taxes on net income
that it  distributes  currently to  shareholders.  However,  the Company will be
subject to federal income tax on any income that it does not distribute and will
be subject to federal  income tax in certain  circumstances  on certain types of
income even though that income is distributed.

                                       33
<PAGE>
     Requirements for  Qualification.  The Code defines a REIT as a corporation,
trust or  association  (1) that is managed by one or more trustees or directors,
(2) the  beneficial  ownership of which is evidenced by  transferable  shares of
stock, or by transferable certificates of beneficial interest, (3) that would be
taxable as a domestic corporation, but for Sections 856 through 859 of the Code,
(4) that is neither a financial  institution nor an insurance company subject to
certain provisions of the Code, (5) the beneficial ownership of which is held by
100 or more persons, (6) that during the last half of each taxable year not more
than 50% in value of the  outstanding  stock  of  which is  owned,  directly  or
indirectly,  by five or fewer  individuals  (as  defined  in the Code to include
certain  entities),  and (7) that meets  certain other tests,  described  below,
regarding the nature of its income and assets. The Code provides that conditions
(1) through (4), inclusive,  must be met during the entire taxable year and that
condition  (5) must be met  during  at least  335 days of a  taxable  year of 12
months, or during a proportionate part of a taxable year of less than 12 months.
The  Company's  Articles of  Incorporation  contain  restrictions  regarding the
transfer  of its  capital  stock  that are  intended  to assist  the  Company in
continuing to satisfy the stock ownership  requirements  described in conditions
(5) and (6).  See  'Description  of  Common  Stock--Restrictions  on  Transfer.'
Moreover,  pursuant to the 1997 Act, for the Company's  taxable years commencing
on or after  January 1, 1998,  if the Company  complies  with  regulatory  rules
pursuant  to which it is  required  to send  annual  letters  to  holders of its
capital  stock  requesting  information  regarding  the actual  ownership of the
capital stock, and the Company does not know, or exercising reasonable diligence
would not have  known,  whether it failed to meet  requirement  (6)  above,  the
Company will be treated as having met the requirement.

     Income Tests.  In order to maintain  qualification  as a REIT,  the Company
must  satisfy  three gross income  requirements,  which are applied on an annual
basis. First, at least 75% of the Company's gross income (excluding gross income
from prohibited  transactions) for each taxable year must be derived directly or
indirectly  from  investments  relating to real  property or  mortgages  on real
property  (including  'rents from real property' and, in certain  circumstances,
interest) or from certain types of temporary  investments.  Second, at least 95%
of  the  Company's  gross  income   (excluding   gross  income  from  prohibited
transactions)  for each  taxable  year must be derived from the same items which
qualify under the 75% income test,  and from  dividends,  interest and gain from
the sale or disposition of stock or securities,  or from any  combination of the
foregoing.  Third,  for its taxable years ending on or before December 31, 1997,
short-term gain from the sale or other disposition of stock or securities,  gain
from prohibited  transactions and gain on the sale or other  disposition of real
property held for less than four years (apart from  involuntary  conversions and
sales of  foreclosure  property)  must  represent less than 30% of the Company's
gross income (including gross income from prohibited transactions).  Pursuant to
the 1997 Act,  the  Company  will not have to meet the 30% test for its  taxable
years commencing on or after January 1, 1998.

     Rents received by the Company will qualify as 'rents from real property' in
satisfying  the gross income  requirements  for a REIT  described  above only if
several  conditions  (related to the identity of the tenant,  the computation of
the rent  payable,  and the nature of the property  leased) are met. The Company
does not anticipate  receiving  rents in excess of 1% of gross revenue that fail
to meet these conditions.  In addition,  for rents received to qualify as 'rents
from real  property,'  the  Company  generally  must not  operate  or manage the
property  or furnish  or render  services  to  tenants,  other  than  through an
'independent   contractor'  from  whom  the  Company  derives  no  revenue.  The
'independent contractor' requirement,  however, does not apply to the extent the
services are 'usually or  customarily  rendered' in  connection  with the rental
space for  occupancy  only and are not  otherwise  considered  'rendered  to the
occupant'  ('Permissible  Services').  The Company will provide certain services
with  respect  to the  properties  through  entities  that  do not  satisfy  the
'independent  contractor' requirements described above. The Company has received
a ruling from the IRS that the provision of certain  services will not cause the
rents  received with respect to the properties to fail to qualify as 'rents from
real  property.'  Based  upon the IRS ruling  and its  experience  in the office
rental  markets in which the  Company's  properties  are  located,  the  Company
believes that all services  provided to tenants will be  considered  'usually or
customarily  rendered'  in  connection  with the  rental  of  office  space  for
occupancy only, although there can be no assurance that the IRS will not contend
otherwise.  If the Company contemplates  providing services,  either directly or
through another entity, in the future that reasonably

                                       34
<PAGE>
might be expected not to meet the 'usual or customary' standard, it will arrange
to have such  services  provided  by an  independent  contractor  from which the
Company will receive no income.

     Pursuant to the 1997 Act, for the Company's  taxable years commencing on or
after January 1, 1998, rents received  generally will qualify as rents from real
property  notwithstanding  the fact that the Company provides  services that are
not Permissible  Services so long as the amount received for such services meets
a de minimis  standard.  The amount received for  'impermissible  services' with
respect to a property  (or, if services are available  only to certain  tenants,
possibly with respect to such tenants)  cannot exceed one percent of all amounts
received,  directly or indirectly,  by the Company with respect to such property
(or, if services are available only to certain tenants, possibly with respect to
such  tenants).  The amount that the Company will be deemed to have received for
performing  'impermissible services' will be the greater of the actual amount so
received or 150% of the direct cost to the Company of providing those services.

     The  Company  may  receive  fees in  consideration  of the  performance  of
management and  administrative  services with respect to properties that are not
owned entirely by the Company.  A portion of such management and  administrative
fees  (corresponding  to that  portion  of a  property  owned by a third  party)
generally will not qualify under the 75% or 95% gross income tests.  The Company
also may receive  other types of income with respect to the  properties  that it
owns that will not qualify for the 75% or 95% gross  income  tests.  The Company
believes,   however,   that  the  aggregate   amount  of  such  fees  and  other
non-qualifying  income in any taxable  year will not cause the Company to exceed
the limits on non-qualifying income under the 75% and 95% gross income tests.

     If the Company  fails to satisfy one or both of the 75% or 95% gross income
tests for any taxable year, it may nevertheless  qualify as a REIT for such year
if it is entitled to relief  under  certain  provisions  of the Code.  It is not
possible,  however,  to state whether in all  circumstances the Company would be
entitled  to the  benefit  of these  relief  provisions.  Even if  these  relief
provisions were to apply,  however,  a 100% tax would be imposed with respect to
the 'excess net income'  attributable  to the failure to satisfy the 75% and 95%
gross income tests.

     Asset Tests.  At the close of each quarter of its taxable year, the Company
also must  satisfy  the  following  three  tests  relating  to the nature of its
assets:  (i) at least 75% of the value of the  Company's  total  assets  must be
represented by 'real estate assets,' cash, cash items and government securities;
(ii) not more than 25% of the  Company's  total  assets  may be  represented  by
securities other than those in the 75% asset class; and (iii) of the investments
included in the 25% asset class, the value of any one issuer's securities (other
than an interest in a partnership,  shares of a 'qualified  REIT  subsidiary' or
another  REIT,  but  including  any  unsecured  debt of  Carr  Realty,  L.P.  or
CarrAmerica Realty, L.P.) owned by the Company may not exceed 5% of the value of
the Company's total assets, and the Company may not own more than 10% of any one
issuer's outstanding voting securities (other than an interest in a partnership,
shares of a  'qualified  REIT  subsidiary'  or another  REIT).  The Company owns
directly  all of the  non-voting  stock,  representing  95%  of the  equity,  of
OmniOffices  and  CarrAmerica  Development  &  Construction.  By  virtue  of its
ownership of Units,  the Company will be considered to own its pro rata share of
the assets of Carr Realty, L.P., including the securities of Carr Services, Inc.
(Carr Services, Inc., OmniOffices and CarrAmerica Development & Construction are
referred  to  collectively  herein as the  'Non-qualified  REIT  Subsidiaries.')
Neither Carr Realty,  L.P.,  CarrAmerica Realty,  L.P., nor the Company will own
more than 10% of the voting  securities of any  Non-qualified  REIT  Subsidiary.
There can be no  assurance,  however,  that the IRS might not  contend  that the
arrangements  between the Company and the  non-qualified  REIT  subsidiaries are
such that the Company  should be  considered  to own more than 10% of the voting
securities of one or both of these  entities.  In addition,  the Company and its
senior management  believe that the Company's pro rata share of the value of the
securities of each of such  Non-qualified  REIT  Subsidiary and of any unsecured
debt of Carr Realty, L.P. and CarrAmerica Realty, L.P. owned by the Company will
not  exceed  5% of the  total  value of the  Company's  assets.  There can be no
assurance,  however,  that the IRS might not  contend  otherwise.  Although  the
Company  plans to take steps to ensure that it continues to satisfy the 5% test,
there can be no assurance that such steps will be successful or will not require
a  reduction  in  the  Company's   overall  interest  in  one  or  more  of  the
Non-qualified REIT Subsidiaries.

                                       35

     Annual  Distribution  Requirements.  To  qualify  as a  REIT,  the  Company
generally  must  distribute  to its  shareholders  at  least  95% of its  income
(excluding  any net capital  gains) from each  taxable  year either  during such
taxable  year or, if certain  procedures  are  followed,  during the  subsequent
taxable year.  The Company will be subject to tax on amounts not  distributed at
regular capital gains and ordinary  corporate tax rates.  With respect to income
distributed  during a year  subsequent to the year in which it was earned by the
Company,  if the Company  does not pay federal  income tax with  respect to such
income, the Company may be subject to a 4% excise tax on such income.

     The  Company  believes  that it has made,  and intends to continue to make,
timely distributions sufficient to satisfy the annual distribution requirements.
It is  possible,  however,  that the  Company,  from time to time,  may not have
sufficient cash or liquid assets to meet the 95%  distribution  requirement.  In
that event,  the Company may  arrange  for  short-term,  or possibly  long-term,
borrowing to permit the payments of required dividends.

     Failure to Qualify.  If the Company fails to qualify for taxation as a REIT
in any  taxable  year,  the  Company  will  be  subject  to tax  (including  any
applicable  alternative  minimum tax) on its taxable income at regular corporate
rates.  Unless  entitled to relief  under  specific  statutory  provisions,  the
Company also will be  disqualified  from taxation as a REIT for the four taxable
years following the year during which qualification was lost. It is not possible
to state  whether in all  circumstances  the  Company  would be entitled to such
statutory relief.

TAXATION OF HOLDERS OF COMMON STOCK

     Taxation of Taxable Domestic Shareholders. As long as the Company qualifies
as a REIT, distributions made to the Company's taxable domestic shareholders out
of current or  accumulated  earnings and profits (and not  designated as capital
gain  dividends)  will be taken into  account by them as  ordinary  income,  and
corporate shareholders will not be eligible for the dividends received deduction
as to such amounts.  For purposes of determining  whether  distributions  on the
shares of Common Stock are out of current or  accumulated  earnings and profits,
the earnings  and profits of the Company  will be  allocated  first to shares of
Preferred Stock, if any, and second to the shares of Common Stock.  There can be
no assurance that the Company will have sufficient earnings and profits to cover
distributions on any shares of Preferred Stock.

     Distributions  that are  designated as capital gain dividends will be taxed
as gains  from the sale or  exchange  of a capital  asset held for more than one
year (to the extent they do not exceed the Company's actual net capital gain for
the taxable year)  without  regard to the period for which the  shareholder  has
held its stock. Corporate shareholders,  however, may be required to treat up to
20% of certain capital gain dividends as ordinary income.

     As  described  below  in  '--Recent  Legislation,'  the  1997  Act  changed
significantly  the taxation of capital gains by taxpayers  who are  individuals,
estates, or trust. It is not clear whether, for the taxable domestic shareholder
who is an individual or an estate or trust,  amounts  designated as capital gain
dividends  will be taxable at the rate  applicable  to  mid-term  capital  gains
(i.e., gains from the sale of capital assets held for more than one year but not
more than 18 months) or at the rate applicable to long-term capital gains (i.e.,
gains  from the sale of  capital  assets  held for more  than 18  months).  This
uncertainty may be clarified by future legislation or regulations.

     Distributions in excess of current or accumulated earnings and profits will
not be  taxable  to a  shareholder  to the  extent  that they do not  exceed the
adjusted  basis of the  shareholder's  shares of Common  Stock,  but rather will
reduce the  adjusted  basis of such shares of Common  Stock.  To the extent that
such distributions exceed the adjusted basis of a shareholder's shares of Common
Stock, they will be included in income as capital gains,  assuming the shares of
Common Stock are a capital asset in the hands of the shareholder.

     In general, a domestic shareholder will realize capital gain or loss on the
disposition  of shares of Common Stock equal to the  difference  between (i) the
amount  of cash  and the fair  market  value of any  property  received  on such
disposition and (ii) the shareholder's adjusted basis of such shares of

                                       36
<PAGE>
Common Stock. With respect to dispositions occurring after July 28, 1997, in the
case of a taxable  domestic  shareholder  who is an  individual  or an estate or
trust,  such gain or loss will be mid-term  capital  gain or loss if such shares
have been held for more than one year but not more than 18 months and  long-term
capital  gain or loss if such shares have been held for more than 18 months.  In
the case of a taxable domestic  shareholder that is a corporation,  such gain or
loss will be  long-term  capital  gain or loss if such shares have been held for
more than one year.  Loss upon a sale or exchange of shares of Common Stock by a
shareholder  who has held such  shares of  Common  Stock for six  months or less
(after  applying  certain  holding  period rules) will be treated as a long-term
capital  loss to the extent of  distributions  from the  Company  required to be
treated by such shareholder as long-term capital gain.

     Pursuant to the 1997 Act, for the Company's  taxable years commencing on or
after  January 1, 1998,  the  Company may elect to require the holders of Common
Stock to include the Company's  undistributed net capital gains in their income.
If the Company  makes such an  election,  the  holders of Common  Stock will (i)
include in their income as long-term capital gains their  proportionate share of
such  undistributed  capital  gains  and  (ii)  be  deemed  to have  paid  their
proportionate share of the tax paid by the Company on such undistributed capital
gains and thereby receive a credit or refund for such amount. A holder of Common
Stock will increase the basis in its Common Stock by the difference  between the
amount of capital  gain  included  in its income and the amount of the tax it is
deemed to have paid.  The  earnings  and profits of the Company will be adjusted
appropriately.  As described  below in '--Recent  Legislation,'  with respect to
such  long-term  capital  gain  of a  taxable  domestic  shareholder  that is an
individual  or an estate or trust,  the IRS has  authority to issue  regulations
that could apply the special tax rate  applicable to sales of  depreciable  real
property by an  individual or an estate or trust to the portion of the long-term
capital gains of an individual or an estate or trust  attributable to deductions
for depreciation taken with respect to depreciable real property.

     Backup  Withholding.  The Company will report to its domestic  shareholders
and the IRS the amount of  dividends  paid during each  calendar  year,  and the
amount  of tax  withheld,  if  any,  with  respect  thereto.  Under  the  backup
withholding  rules,  a shareholder  may be subject to backup  withholding at the
rate  of 31%  with  respect  to  dividends  paid  unless  such  holder  (a) is a
corporation or comes within certain other exempt  categories and, when required,
demonstrates  this fact,  or (b) provides a taxpayer  identification  number and
certifies as to no loss of exemption from backup  withholding.  Amounts withheld
as backup  withholding will be creditable  against the stockholder's  income tax
liability.  In  addition,  the  Company may be required to withhold a portion of
capital gain  distributions  made to any  shareholders who fail to certify their
non-foreign  status to the Company.  See  '--Taxation of Non-U.S.  Shareholders'
below.  Additional  issues may arise  pertaining  to  information  reporting and
backup withholding with respect to Non-U.S. Shareholders (persons other than (i)
citizens or residents of the United States,  (ii) corporations,  partnerships or
other entities  created or organized  under the laws of the United States or any
political  subdivision  thereof, and (iii) estates or trusts the income of which
is subject to United States  federal income  taxation  regardless of its source)
and Non-U.S.  Shareholders should consult their tax advisors with respect to any
such information reporting and backup withholding requirements.

     The Treasury Department has recently issued proposed regulations  regarding
the withholding and information reporting rules discussed above. In general, the
proposed  regulations do not alter the  substantive  withholding and information
reporting requirements but unify current certification  procedures and forms and
clarify and modify reliance  standards.  If finalized in their current form, the
proposed  regulations  would  generally  be effective  for  payments  made after
December 31, 1997, subject to certain transition rules.

     Taxation of Tax-Exempt Shareholders. As a general rule, amounts distributed
to a tax-exempt  entity do not constitute  'unrelated  business  taxable income'
('UBTI'),  and thus  distributions  by the  Company to a  stockholder  that is a
tax-exempt entity should also not constitute UBTI,  provided that the tax-exempt
entity has not  financed  the  acquisition  of its  shares of Common  Stock with
'acquisition  indebtedness'  within  the  meaning  of the Code and the shares of
Common Stock are not  otherwise  used in an  unrelated  trade or business of the
tax-exempt  entity.  However,  under  the  Revenue  Reconciliation  Act of 1993,
distributions by a REIT to a tax-exempt  employee's pension trust that owns more
than 10%

                                       37
<PAGE>
of the REIT will be  treated  as UBTI in an amount  equal to the  percentage  of
gross income of the REIT that is derived from an  'unrelated  trade or business'
(determined  as if the REIT were a pension trust) divided by the gross income of
the REIT for the year in which the dividends  are paid.  This rule only applies,
however,  if (i) the percentage of gross income of the REIT that is derived from
an unrelated  trade or business for the year in which the  dividends are paid is
at least 5%, (ii) the REIT qualifies as a REIT only because the pension trust is
not treated as a single individual for purposes of the 'five-or-fewer rule' (see
'--Taxation of the  Company--Requirements  for Qualification'  above), and (iii)
(A) one pension trust owns more than 25 percent of the value of the REIT or, (B)
a group of pension trusts individually holding more than 10 percent of the value
of the REIT  collectively own more than 50 percent of the value of the REIT. The
Company currently does not expect that this rule will apply.

     Taxation of Non-U.S. Shareholders. The rules governing U.S. federal income
taxation of Non-U.S. Shareholders are complex, and no attempt will be made
herein to provide more than a limited summary of such rules. Prospective
Non-U.S. Shareholders should consult with their own tax advisors to determine
the impact of U.S. federal, state and local income tax laws with regard to an
investment in Common Stock, including any reporting requirements.

     Distributions  that are not attributable to gain from sales or exchanges by
the Company of U.S. real property interests and not designated by the Company as
capital gain  dividends  will be treated as dividends of ordinary  income to the
extent that they are made out of current or accumulated  earnings and profits of
the Company.  Such distributions,  ordinarily,  will be subject to a withholding
tax equal to 30% of the gross amount of the  distribution  unless an  applicable
tax treaty reduces that tax.  Distributions in excess of current and accumulated
earnings  and  profits  of  the  Company  will  not  be  taxable  to a  Non-U.S.
Shareholder  to the extent  that they do not exceed  the  adjusted  basis of the
shareholder's  Common Stock,  but rather will reduce the adjusted  basis of such
Common Stock. To the extent that such distributions exceed the adjusted basis of
a Non-U.S.  Shareholder's  Common Stock, they will give rise to tax liability if
the Non-U.S.  Shareholder would otherwise be subject to tax on any gain from the
sale or  disposition  of its Common Stock as described  below.  As a result of a
legislative  change made by the Small  Business Job  Protection  Act of 1996, it
appears that the Company will be required to withhold 10% of any distribution in
excess  of  the  Company's   current  and  accumulated   earnings  and  profits.
Consequently,  although  the Company  intends to withold at a rate of 30% on the
entire amount of any distribution  (or a lower  applicable  treaty rate), to the
extent that the Company does not do so, any portion of a distribuion not subject
to  withholding  at a rate of 30% (or a lower  applicable  treaty  rate) will be
subject to withholding at a rate of 10%. However,  the Non-U.S.  Shareholder may
seek from the IRS a refund of such  amounts  from the IRS if it is  subsequently
determined  that  such  distribution  was,  in fact,  in excess  of  current  or
accumulated  earnings  and  profits  of the  Company,  and the  amount  withheld
exceeded the Non-U.S.  Shareholder's  United States tax liability,  if any, with
respect to the distribution.

     For any year in which the Company qualifies as a REIT,  distributions  that
are  attributable  to gain from sales or exchanges  by the Company of U.S.  real
property interests will be taxed to a Non-U.S.  Shareholder under the provisions
of the Foreign  Investment  in Real  Property Tax Act of 1980  ('FIRPTA') at the
normal  capital  gain rates  applicable  to  domestic  shareholders  (subject to
applicable  alternative minimum tax and a special alternative minimum tax in the
case of nonresident alien individuals).  Also,  distributions  subject to FIRPTA
may be subject to a 30% branch profits tax in the hands of a corporate  Non-U.S.
Shareholder not entitled to treaty relief or exemption.  The Company is required
by applicable  Treasury  Regulations to withhold 35% of any distribution that is
or could be  designated  by the Company as a capital gain  dividend.  The amount
withheld is creditable against the Non-U.S. Shareholder's FIRPTA tax liability.

     Although  the law is not  entirely  clear on the  matter,  it appears  that
amounts  designated  by the Company  pursuant  to the 1997 Act as  undistributed
capital  gains  in  respect  of  shares  of  Common  Stock  (see   'Taxation  of
Shareholders--Taxation of Taxable Domestic Shareholders' above) would be treated
with respect to Non-U.S.  Shareholders  in the manner  outlined in the preceding
paragraph  for actual  distributions  by the Company of capital gain  dividends.
Under that  approach,  the  Non-U.S.  Shareholders  would be able to offset as a
credit against their United States federal income tax

                                       38
<PAGE>
liability  resulting  therefrom their proportionate share of the tax paid by the
Company on such  undistributed  capital  gains  (and to  receive  from the IRS a
refund to the extent their  proportionate  share of such tax paid by the Company
were to exceed their actual United States federal income tax liability).

     Gain  recognized  by a  Non-U.S.  Shareholder  upon a sale of Common  Stock
generally  will not be taxed  under  FIRPTA if the  Company  is a  'domestically
controlled  REIT,'  defined  generally  as a REIT in which at all times during a
specified  testing  period less than 50% in value of the stock was held directly
or indirectly by foreign  persons.  As of September 30, 1997,  SC-USREALTY  held
approximately  42.6% in value of the outstanding Common Stock of the Company. In
the  event  that  SC-USREALTY  and other  stockholders  of the  Company  who are
Non-U.S. Shareholders own collectively 50% or more, in value, of the outstanding
stock of the Company,  the Company would cease to be a 'domestically  controlled
REIT.'

     If the Company  does not  qualify as a  'domestically  controlled  REIT,' a
Non-U.S.  Shareholder's  sale of securities of the Company  generally still will
not be  subject  to U.S.  tax  under  FIRPTA as a sale of a U.S.  real  property
interest, provided that (i) the securities are 'regularly traded' (as defined by
the applicable  Treasury  Regulations) on an established  securities market, and
(ii) the selling Non-U.S.  Shareholder held 5% or less of the value of any class
or  series  of the  Company's  outstanding  securities  at all  times  during  a
specified  testing period.  The Company  believes that the Common Stock would be
considered  to be 'regularly  traded' for this  purpose,  and the Company has no
actual knowledge of any Non-U.S. Shareholder (other than SC-USREALTY) that holds
in excess of 5% of the Company's  capital stock.  In order to assist the Company
in qualifying as a 'domestically controlled REIT,' the Articles of Incorporation
contain  certain  provisions  preventing  any Non-U.S.  Shareholder  (other than
SC-USREALTY  and  its  affiliates)  from  acquiring  additional  shares  of  the
Company's capital stock if, as a result of such  acquisition,  the Company would
fail to qualify as a  'domestically  controlled  REIT'  (computed  assuming that
SC-USREALTY  owns the maximum  percentage  of the  Company's  capital stock that
SC-USREALTY  is  permitted  to own under the  Special  Shareholder  Limit).  The
Company is unlikely to be able to advise a prospective Non-U.S. Shareholder that
its purchase of any shares of the Company's capital stock would not violate this
prohibition,  thereby  subjecting such prospective  Non-U.S.  Shareholder to the
adverse consequences described under 'Description of Common Stock-- Restrictions
on Transfer--Violation of Ownership Limits.' Accordingly,  an acquisition of the
Company's capital stock would not likely be a suitable investment for Non-U.S.
Shareholders other than SC-USREALTY.

     If the gain on the sale of Common  Stock  were to be  subject  to tax under
FIRPTA,  the  Non-U.S.  Shareholder  would be subject to the same  treatment  as
domestic   shareholders  with  respect  to  such  gain  (subject  to  applicable
alternative  minimum  tax and a special  alternative  minimum tax in the case of
nonresident alien  individuals),  and the purchaser of the Common Stock would be
required to withhold and remit to the IRS 10% of the purchase price.

RECENT LEGISLATION

     As  described  above,  1997  Act  contains  certain  changes  to  the  REIT
qualification  requirements  and to the  taxation  of  REITs.  The 1997 Act also
contains certain changes to the taxation of capital gains of individuals, trusts
and estates.

     Capital Gain Rates. Subject to certain exceptions, for individuals,  trusts
and  estates  the  maximum  rate of tax on the net  capital  gain from a sale or
exchange  occurring  after July 28, 1997 of a long-term  capital asset (i.e.,  a
capital asset held for more than 18 months) has been reduced to from 28% to 20%.
The maximum  rate has been  reduced to 18% for  capital  assets  acquired  after
December  21,  2000 and held for more  than five  years.  The  maximum  rate for
mid-term  capital  assets (i.e.,  capital assets held for more than one year but
not more than 18 months)  remains at 28%. The maximum rate for net capital gains
attributable  to the sale of  depreciable  real  property  held for more than 18
months in 25% to the extent of the prior  deductions for  'unrecaptured  Section
1250 gain' (that is depreciation deductions not otherwise recaptured as ordinary
income under the existing depreciation  recapture rules).  Capital gain from the
sale of depreciable  real property held for more than 18 months allocated by the
Company to a

                                       39
<PAGE>
non-corporate shareholder will be subject to the 25% rate to the extent that the
capital  gain on the real  property  sold by the Company  does not exceed  prior
depreciation deductions with respect to such property. The 1997 Act provides the
IRS with authority to issue  regulations that could,  among other things,  apply
these rates on a look-through basis in the case of 'pass-through'  entities such
as the Company. The taxation of capital gains of corporations was not changed by
the 1997 Act.

     REIT  Provisions.  In addition to the provisions  discussed above, the 1997
Act  contains a number of technical  provisions  that either (i) reduce the risk
that the Company will inadvertently  cease to qualify as a REIT, or (ii) provide
additional  flexibility  with which the Company can meet the REIT  qualification
requirements.  These  provisions  are effective for the Company's  taxable years
commencing on or after January 1, 1998.

OTHER TAX CONSIDERATIONS

     Entity Classification. A significant number of the Company's investments
are through Carr Realty, L.P. and CarrAmerica Realty, L.P. If either Carr
Realty, L.P. or CarrAmerica Realty, L.P. were treated as an association, the
entity would be taxable as a corporation and therefore would be subject to an
entity level tax on its income. In such a situation, the character of the
Company's assets and items of gross income would change and would preclude the
Company from qualifying as a REIT (see 'Taxation of the Company--Income Tests'
and '--Asset Tests').

     Prior to January 1, 1997,  an  organization  formed as a  partnership  or a
limited  liability  company was treated as a partnership  for federal income tax
purposes  rather  than as a  corporation  only if it had no more than two of the
four corporate  characteristics  that the Treasury Regulations in effect at that
time used to  distinguish  a partnership  from a  corporation  for tax purposes.
These four  characteristics  were (i) continuity of life, (ii) centralization of
management,  (iii) limited liability and (iv) free transferability of interests.
Under final Treasury  Regulations  which became  effective  January 1, 1997, the
four factor test has been eliminated and an entity formed as a partnership or as
a limited  liability  company will be taxed as a partnership  for federal income
tax purposes,  unless it specifically elects otherwise.  The Regulations provide
that the IRS will not challenge the classification of an existing partnership or
limited  liability  company for tax periods prior to January 1, 1997, so long as
(1) the entity had a reasonable  basis for its claimed  classification,  (2) the
entity and all of its members  recognized the federal income tax consequences of
any changes in the entity's classification within the 60 months prior to January
1,  1997,  and (3)  neither  the  entity  nor any  member of the entity had been
notified  in writing on or before May 8, 1996,  that the  classification  of the
entity was under examination by the IRS.

     The Company believes that Carr Realty, L.P. and CarrAmerica Realty, L.P.
each will be treated as a partnership for federal income tax purposes (and not
as an association taxable as a corporation).

     Tax  Allocations   with  Respect  to  the  Properties.   When  property  is
contributed to a partnership in exchange for an interest in the partnership, the
partnership  generally takes a carryover basis in that property for tax purposes
equal to the adjusted basis of the contributing partner in the property,  rather
than a basis  equal to the fair  market  value  of the  property  at the time of
contribution  (this  difference  is referred to as 'Book-Tax  Difference').  The
partnership agreements of each of Carr Realty, L.P. and CarrAmerica Realty, L.P.
require that  allocations  of income,  gain,  loss and deduction with respect to
each property  contributed to those  partnerships be made in a manner consistent
with the  special  rules in 704(c) of the Code and the  regulations  thereunder,
which will tend to  eliminate  the  Book-Tax  Differences  with  respect to such
contributed  properties over the life of the  partnership.  However,  because of
certain technical  limitations,  the special  allocation rules of Section 704(c)
may not always entirely eliminate the Book-Tax  Difference on an annual basis or
with  respect  to a  specific  taxable  transaction  such as a sale.  Thus,  the
carryover basis of such contributed properties in the hands of Carr Realty, L.P.
or  CarrAmerica  Realty,  L.P.,  as  applicable  could  cause the  Company to be
allocated  lower amounts of depreciation  and other  deductions for tax purposes
than would be allocated to the Company if all such  contributed  properties were
to have a tax  basis  equal  to  their  fair  market  values  at the  time  such
properties were contributed to Carr Realty, L.P. or CarrAmerica Realty, L.P., as
applicable.  The  foregoing  rules also apply for  purposes of  determining  the
Company's earnings and profits. The

                                       40
<PAGE>
application of such rules over time could result in a higher portion of
distributions to shareholders being taxed as dividends. See '--Taxation of
Holders of Common Stock.'

     Non-Qualified REIT Subsidiaries. The Non-qualified REIT Subsidiaries do not
qualify as REITs and thus pay federal,  state and local income taxes  (including
District  of  Columbia  franchise  tax) on their net income at normal  corporate
rates. To the extent the  Non-qualified  REIT  Subsidiaries  are required to pay
federal,  state and local income taxes,  the cash available for  distribution to
stockholders will be reduced accordingly.

     State and Local Taxes;  District of Columbia  Unincorporated  Business Tax.
The Company and its  stockholders  may be subject to state or local  taxation in
various  state  or  local  jurisdictions,  including  those  in which it or they
transact  business or reside.  The state and local tax  treatment of the Company
and its  stockholders  may not  conform to the federal  income tax  consequences
discussed   above.  In  this  regard,   the  District  of  Columbia  imposes  an
unincorporated  business income tax, at the rate of 9.975%,  on the 'District of
Columbia  taxable  income' of  partnerships  doing  business in the  District of
Columbia.  Because many of the properties owned by Carr Realty, L.P. are located
in the District of Columbia,  the  Company's  share of the 'District of Columbia
taxable  income' of Carr Realty,  L.P. will be subject to this tax. Carr Realty,
L.P.  has taken  steps to  attempt  to  reduce  the  amount  of  income  that is
considered 'District of Columbia taxable income,' but it is likely that at least
some  portion of the  income  attributable  to Carr  Realty,  L.P.'s  properties
located in the District of Columbia  will be subject to the District of Columbia
tax. To the extent Carr Realty, L.P. is required to pay the District of Columbia
unincorporated  business income tax, the cash available for  distribution to the
Company  and,  therefore,  to its  stockholders  as  dividends  will be  reduced
accordingly. This tax would not apply if the Company were to own and operate its
assets directly,  rather than through Carr Realty,  L.P.; however, the Company's
ability  to  eliminate  Carr  Realty,  L.P.  and thus own  directly  the  assets
currently owned by Carr Realty, L.P. is severely limited.

                              PLAN OF DISTRIBUTION

GENERAL

     The Company may sell Securities in or through underwriters for public offer
and sale by them,  and also may sell  Securities  offered  hereby  to  investors
directly or through agents.  Any such underwriter or agent involved in the offer
and  sale  of  the  Securities  will  be  named  in  the  applicable  Prospectus
Supplement.

     Underwriters  may offer and sell the Securities at a fixed price or prices,
which may be changed,  at prices related to the prevailing  market prices at the
time of sale or at negotiated  prices.  The Company also may, from time to time,
authorize  underwriters  acting  as the  Company's  agents  to  offer  and  sell
Securities  upon terms and  conditions  set forth in the  applicable  Prospectus
Supplement.  In connection with the sale of the Securities,  underwriters may be
deemed  to  have  received   compensation  from  the  Company  in  the  form  of
underwriting  discounts or  commissions  and may also receive  commissions  from
purchasers of the  Securities for whom they may act as agent.  Underwriters  may
sell Securities to or through dealers, and such dealers may receive compensation
in the form of  discounts,  concessions  or  commissions  from the  underwriters
and/or commissions from the purchasers for whom they may act as agent.

     Any underwriting compensation paid by the Company to underwriters or agents
in  connection  with  the  offering  of  the  Securities,   and  any  discounts,
concessions or commissions  allowed by  underwriters to  participating  dealers,
will be set forth in the applicable Prospectus Supplement. Underwriters, dealers
and agents  participating in the distribution of the Securities may be deemed to
be  underwriters,  and any  discounts and  commissions  received by them and any
profit  realized  by  them on  resale  of the  Securities  may be  deemed  to be
underwriting  discounts and commissions under the Securities Act.  Underwriters,
dealers and agents may be entitled, under agreements to be entered into with the
Company,  to  indemnification  against and  contribution  toward  certain  civil
liabilities, including liabilities under the Securities Act.

                                       41
<PAGE>
     If so indicated in the applicable Prospectus  Supplement,  the Company will
authorize  underwriters  or other  persons  acting  as the  Company's  agents to
solicit offers by certain  institutions to purchase  Securities from the Company
at the public offering price set forth in such Prospectus Supplement pursuant to
delayed delivery contracts  ('Contracts')  providing for payment and delivery on
the date or dates stated in such  Prospectus  Supplement.  Each Contract will be
for an amount not less than,  and the aggregate  principal  amount of Securities
sold pursuant to Contracts  shall be neither less nor more than,  the respective
amounts stated in the applicable Prospectus  Supplement.  Institutions with whom
Contracts,  when authorized,  may be made include  commercial and savings banks,
insurance  companies,  pension  funds,  investment  companies,  educational  and
charitable  institutions,  and  other  institutions,  but  will in all  cases be
subject to the  approval of the  Company.  Contracts  will not be subject to any
conditions  except (i) the purchase by an institution of the Securities  covered
by its Contracts shall not at the time of delivery be prohibited  under the laws
of any  jurisdiction in the United States to which such  institution is subject,
and (ii) if the  Securities  are being sold to  underwriters,  the Company shall
have sold to such underwriters the total principal amount of the Securities less
the principal amount thereof covered by Contracts.

     Certain of the  underwriters  and their  affiliates  may be  customers  of,
engage  in  transactions  with and  perform  services  for the  Company  and its
Subsidiaries in the ordinary course of business.

PARTICIPATION RIGHTS

     In conjunction  with the  SC-USREALTY  Transaction,  so long as SC-USREALTY
owns at least 25% of the  outstanding  Common  Stock of the  Company  on a fully

circumstances),   upon  compliance  with  certain  specified  conditions,  to  a
participation  right  to  purchase  or  subscribe  for,  either  as part of such
issuance or in a concurrent  issuance,  a total number of shares of Common Stock
or  Preferred  Stock,  as the case may be, equal to up to 30% (or 35% in certain
circumstances)  of the total  number of shares or of Common  Stock or  Preferred
Stock,  as  applicable,  proposed  to be issued by the  Company.  All  purchases
pursuant to such participation  rights will be at the same price and on the same
terms and conditions as are applicable to other purchasers hereunder.
