               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

   Certain statements in this prospectus supplement and accompanying
prospectus, and in the documents incorporated by reference in this prospectus
supplement and accompanying prospectus, constitute "forward-looking statements"
within the meaning of the Private Securities Litigation Reform Act of 1995.
Such forward-looking statements involve known and unknown risks, uncertainties

from any future results, performance, dividends, achievements or transactions
expressed or implied by such forward-looking statements. Such factors include,
among others, the following:

   .   National and local economic, business and real estate conditions that
       will, among other things, affect:
      .   demand for office properties,
      .   the ability of the general economy to recover timely from the current
          economic downturn,
      .   availability and creditworthiness of tenants,
      .   the level of lease rents, and
      .   the availability of financing for both our tenants and us;
   .   Adverse changes in the real estate markets, including, among other
       things:
      .   competition with other companies, and
      .   risks of real estate acquisition and development (including the
          failure of pending acquisitions to close and pending developments to
          be completed on time and within budget);
   .   Possible charges or payments resulting from our guarantees of certain
       leases of HQ Global Workplaces, Inc.;
   .   Actions, strategies and performance of affiliates that we may not
       control or companies in which we have made investments;
   .   Ability to obtain insurance at a reasonable cost;
   .   Our ability to maintain our status as a REIT for federal income tax
       purposes;
   .   Governmental actions and initiatives; and
   .   Environmental/safety requirements.

future results, performance, achievements or transactions, see the documents
filed by us from time to time with the SEC, in particular the section titled
"The Company--Risk Factors" in our annual report on Form 10-K for the year
ended December 31, 2001, and the section titled "Risk Factors" beginning on
page 2 of the accompanying prospectus.

                                      S-1



                         THE COMPANY AND THE GUARANTOR

   We are a fully integrated, self-administered and self-managed
publicly-traded real estate investment trust. We focus on the acquisition,
development, ownership and operation of high-quality office properties located
primarily in selected markets across the United States.

   As of September 30, 2002, we owned, directly and indirectly through our
subsidiaries, including CarrAmerica Realty, L.P., a greater than 50% interest
in 258 operating office properties and two office properties and one
residential property under construction. We also owned minority interests,
ranging from 15% to 50%, in 36 operating office properties and five properties
under construction.

   As of September 30, 2002, Fitch Rating Services and Standard & Poors have
each assigned their BBB rating to our prospective senior unsecured debt
offerings. Moody's Investor Service has assigned a negative outlook and its
Baa2 rating to our prospective senior unsecured debt offerings.

   CarrAmerica Realty, L.P., or the "Guarantor," will be unconditionally
guaranteeing the notes we are offering. Through a wholly-owned subsidiary, we
serve as the Guarantor's sole general partner. As of September 30, 2002, we
indirectly owned approximately 90.9% of the Guarantor's partnership units. The
Guarantor focuses on the acquisition, development, ownership and operation of
office properties, located primarily in selected markets across the United
States.

                                USE OF PROCEEDS

   We expect to use the entire net proceeds of approximately $49.6 million
(after deducting the placement agent fee and our offering expenses) to repay
indebtedness under our $500 million unsecured credit facility with JPMorgan
Chase Bank, as agent for a group of banks. The line of credit expires in June
2004, and we can extend the line for an additional year at our option. As of
November 6, 2002, $200.0 million was drawn on the credit facility, $5.2 million
in letters of credit were outstanding and we had approximately $294.8 million
available for borrowing. As of November 6, 2002, the credit facility carried an
interest rate of 2.5%, or 70 basis points over 30-day LIBOR. The total
commitment carries a 20 basis point facility fee. We will use the increased
availability under our credit facility for general corporate purposes,
including repaying secured indebtedness that is secured by some of our
properties. Affiliates of Banc of America Securities LLC, J.P. Morgan
Securities Inc. and Wachovia Securities, Inc., three of the placement agents of
this offering, are lenders under our credit facility. These affiliates will
receive their proportionate share of the amount of the credit facility to be
repaid with the proceeds of this offering. The portion of the net proceeds of
this offering not used to repay our credit facility will be used for general
corporate purposes.

                      RATIO OF EARNINGS TO FIXED CHARGES

   The following table sets forth our and the Guarantor's ratio of earnings to
fixed charges for the periods indicated:

   CarrAmerica Realty, L.P.......     2.12x     1.21x 2.28x 1.86x 2.23x 2.38x


   The ratios of earnings to fixed charges were computed by dividing earnings
by fixed charges. For this purpose, earnings consist of income from continuing
operations before income taxes, minority interest and discontinued operations
plus the amortization of capitalized interest and fixed charges (excluding
interest cost capitalized). Fixed charges consist of interest expense
(including interest costs capitalized) and the amortization of debt issuance
costs.

                                      S-2



   In accordance with Statement of Financial Accounting (SFAS) No. 144
"Accounting for the Impairment or Disposal of Long-Lived Assets," if applicable
criteria are met, we are required to report the operating results of properties
sold or classified as held for sale on or after January 1, 2002 and the related
gain (loss) on sale in discontinued operations. We are also required to
reclassify operating results of such properties to discontinued operations for
all prior periods presented. The ratios of earnings to fixed charges for each
of the years ended December 31, 1997 through December 31, 2001 have been
calculated to reflect the reclassifications required as a result of the
application of SFAS No. 144.

                             DESCRIPTION OF NOTES

   The following description of the particular terms of the notes offered
hereby supplements, and to the extent inconsistent replaces, the description of
the general terms and provisions of debt securities set forth under the caption
"Description of Debt Securities" beginning on page 10 of the accompanying
prospectus.

   The notes will constitute a separate series of securities to be issued
pursuant to the indenture, dated as of January 11, 2002, among us, CarrAmerica
Realty, L.P., as guarantor, and U.S. Bank National Association, as trustee, and
pursuant to resolutions of our board of directors and an officers' certificate,
to be dated as of November 20, 2002, setting forth the principal, interest and
other terms of the notes. The terms of the notes will include those provisions
contained in the indenture and the officers' certificate and those made part of
the indenture by reference to the Trust Indenture Act of 1939, as amended. The
following summary of the notes is qualified in its entirety by reference to the
indenture and the officers' certificate.

General

   The notes will be our direct, senior unsecured obligations and will rank
equally with all of our other unsecured and unsubordinated indebtedness from
time to time outstanding. However, the notes are effectively subordinated to
our mortgages and other of our secured indebtedness and certain indebtedness of
our consolidated subsidiaries. We had approximately $496.8 million of secured
debt outstanding at September 30, 2002. Our total outstanding indebtedness at
that date, including debt of our consolidated subsidiaries, was approximately
$1.6 billion.

   The notes will bear interest at 5.261% per year and will mature on November
30, 2007. The notes will bear interest from November 20, 2002, payable
semi-annually in arrears on May 30 and November 30 of each year, commencing on
May 30, 2003 (each such date being an "interest payment date") to the persons
in whose name the notes are registered in the security register on the
preceding May 15 or November 15, whether or not a business day, as the case may
be (each such date being a "regular record date"). Interest on the notes will
be computed on the basis of a 360-day year of twelve 30-day months.

   If any interest payment date or the maturity date falls on a day that is not
a business day, the required payment will be made on the next business day as
if it were made on the date such payment was due and no interest shall accrue
on the amount so payable for the period from and after that interest payment
date or the maturity date, as the case may be. A business day means any day,
other than a Saturday or Sunday, on which banks in The City of New York are not
required or authorized by law or executive order to close.

   The notes will be payable at the corporate trust office maintained by the
trustee for that purpose at 100 Wall Street, 16th Floor, New York, New York
10005, or elsewhere as provided in the indenture, provided that, at our option,
payment of interest may be made by check mailed to the address of the person
entitled thereto as it appears in the security register or by wire or other
transfer of funds to that person at an account maintained within the United
States.

   The notes will only be issued in fully registered book-entry form in
denominations of $1,000 and integral multiples of $1,000. See "Book Entry
Securities" in the accompanying prospectus.

                                      S-3



   The notes are not repayable at the option of any holder before maturity. The
notes will not be subject to a sinking fund.

   The defeasance and covenant defeasance provisions of the indenture,
described under "Description of Debt Securities--Discharge, Defeasance and
Covenant Defeasance" in the accompanying prospectus, apply to the notes.

   Please refer to the section entitled "Description of Debt Securities--Events
of Default" in the accompanying prospectus for a description of the events of
default under the indenture.

   Please refer to the sections entitled "--Certain Covenants" in this
prospectus supplement and "Description of Debt Securities--Additional Covenants
and/or Modifications to the Covenants Described Above" in the accompanying
prospectus for a description of the covenants applicable to the notes.

   Except as described in this prospectus supplement under "--Certain
Covenants" and under "Description of Debt Securities--Merger, Consolidation or
Sale" in the accompanying prospectus, the indenture does not contain any other
provisions that would limit our ability to incur indebtedness or that would
afford holders of the notes protection in the event of

  .  a highly leveraged or similar transaction involving us or any of our
     subsidiaries or affiliates,

  .  a change of control, or

  .  a reorganization, restructuring, merger or similar transaction involving
     us that may adversely affect the holders of the notes.

   In addition, subject to the limitations set forth under "Description of Debt
Securities--Merger, Consolidation or Sale" in the accompanying prospectus, we
may, in the future, enter into certain transactions such as the sale of all or
substantially all of our assets or the merger or consolidation of us that would
increase the amount of indebtedness or substantially reduce or eliminate our
assets, which may have an adverse effect on our ability to service our
indebtedness, including the notes. We have no present intention to enter into
any such transaction.

Guarantee

   The notes will be guaranteed as to payment of principal, interest and
premium (arising from the Make-Whole Amount), if any, by CarrAmerica Realty,
L.P., as described in the accompanying prospectus under "Description of Debt
Securities--Guarantee." Through a wholly-owned subsidiary, we serve as the
Guarantor's sole general partner, and as of September 30, 2002, we indirectly
owned approximately 90.9% of the Guarantor's partnership units. The guarantee
of the notes is:

  .  an unsecured obligation of the Guarantor,

  .  is effectively subordinated to mortgage and other secured indebtedness of
     the Guarantor, and

  .  ranks equally with prior guarantees by the Guarantor of our other publicly
     held debt and the Guarantor's other unsecured and unsubordinated
     indebtedness from time to time outstanding.

   As of September 30, 2002 the Guarantor had approximately $196.8 million of
outstanding indebtedness, of which $39.1 million was owed to us and $157.7
million was secured by properties owned by the Guarantor. The indenture does
not limit the Guarantor's ability to incur additional indebtedness, including
secured indebtedness. If we sell or dispose of all of the Capital Stock of the
Guarantor to another person in compliance with the indenture, the Guarantor
will be released from its guarantee to the extent that it is also released from
its other guarantees of our debt.


                                      S-4



Optional Redemption

   The notes may be redeemed at any time at our option, in whole or in part, at
a "Redemption Price" equal to the sum of:

  .  the principal amount of the notes being redeemed plus accrued interest
     thereon to the redemption date; and

  .  the Make-Whole Amount, if any, with respect to those notes.

   If notice of redemption has been given as provided in the indenture and
funds for the redemption of any notes called for redemption have been made
available on the redemption date specified in the notice, the notes will cease
to bear interest on the date fixed for the redemption specified in the notice
and the only right of the holders of the notes from and after the redemption
date will be to receive payment of the Redemption Price upon surrender of the
notes in accordance with the notice.

   Notice of any optional redemption of any notes will be given to holders at
their addresses, as shown in the security register, 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 notes held by holder to be redeemed.

   If less than all the notes are to be redeemed at our option, we will notify
the trustee under the indenture at least 45 days prior to the giving of notice
of redemption, or such shorter period as may be satisfactory to the trustee, of
the aggregate principal amount of the notes to be redeemed and their redemption
date. The trustee under the indenture will select, in such manner as it deems
fair and appropriate, no less than 60 days prior to the date of redemption, the
notes to be redeemed in part.

   As used in this prospectus supplement "Make-Whole Amount" means, in
connection with any optional redemption of any notes, the excess, if any, of:

  .  the aggregate present value as of the date of redemption or accelerated
     payment of each dollar of principal being redeemed or paid and the amount
     of interest, exclusive of interest accrued to the date of redemption or
     accelerated payment, that would have been payable in respect of each
     dollar if the redemption or accelerated payment had not been made,
     determined by discounting, on a semi-annual basis, the principal and
     interest at the Reinvestment Rate (as defined below), determined on the
     third business day preceding the date notice of the redemption is given,
     from the respective dates on which the principal and interest would have
     been payable if the redemption or accelerated payment had not been made,
     to the date of redemption or accelerated payment; over

  .  the aggregate principal amount of the notes being redeemed or paid.

   "Reinvestment Rate" means 0.30% plus the arithmetic mean of the yields under
the headings "Week Ending" published in the most recent Statistical Release
under the caption "Treasury Constant Maturities" for the maturity (rounded to
the nearest month) corresponding to the remaining life to maturity of the
notes, as of the payment date of the principal being redeemed. If no maturity
exactly corresponds to the maturity, yields for the two published maturities
most closely corresponding to that maturity shall be calculated pursuant to the
immediately preceding sentence and the Reinvestment Rate shall be interpolated
or extrapolated from those yields on a straight-line basis, rounding each of
the relevant periods to the nearest month. For purposes of calculating the
Reinvestment Rate, the most recent Statistical Release published prior to the
date of determination of the Make-Whole Amount shall be used.

   "Statistical Release" means the statistical release designated "H.15(519)"
or any successor publication which is published weekly by the Federal Reserve
System and which establishes yields on actively traded United States government
securities adjusted to constant maturities or, if the statistical release is
not published at the time of any determination of the Make-Whole Amount, then
such other reasonably comparable index which shall be designated by us.

                                      S-5



Certain Covenants

   The indenture contains four principal covenants on the limitation of
Indebtedness (as defined below). Each of these covenants is described as
follows.

  Debt to Total Assets Ratio Covenant

   Under the indenture, neither we nor any of our Subsidiaries (as defined
below) will be permitted to incur any Indebtedness if, immediately after giving
effect to the incurrence of that additional Indebtedness and the application of
the proceeds thereof, the aggregate principal amount of our and our
Subsidiaries' outstanding Indebtedness on a consolidated basis determined in
accordance with generally accepted accounting principles, or GAAP, is greater
than 60% of the sum of (without duplication):

  .  our and our Subsidiaries' Total Assets (as defined below) as of the end of
     the calendar quarter covered in our Annual Report on Form 10-K or our
     Quarterly Report on Form 10-Q, as the case may be, most recently filed
     with the SEC (or, if the filing is not permitted under the Securities
     Exchange Act of 1934, as amended (the "Exchange Act"), with the trustee)
     before the incurrence of the additional Indebtedness, and

  .  the purchase price of any real estate assets or mortgages receivable
     acquired and the amount of any securities offering proceeds received (to
     the extent that the proceeds were not used to acquire real estate assets
     or mortgages receivable or used to reduce Indebtedness) by us or any of
     our Subsidiaries since the end of the calendar quarter, including those
     proceeds obtained in connection with the incurrence of the additional
     Indebtedness.

  Secured Debt to Total Assets Ratio Covenant

   Neither we nor any of our Subsidiaries will be permitted to incur any
Indebtedness secured by any Encumbrance (as defined below) upon any of our or
our Subsidiaries' property if, immediately after giving effect to the
incurrence of the additional Indebtedness and the application of the proceeds
thereof, the aggregate principal amount of all our and our Subsidiaries'
outstanding Indebtedness on a consolidated basis which is secured by any
Encumbrance on our and our Subsidiaries' property is greater than 40% of the
sum of (without duplication):

  .  our and our Subsidiaries' Total Assets as of the end of the calendar
     quarter covered in our Annual Report on Form 10-K or our Quarterly Report
     on Form 10-Q, as the case may be, most recently filed with the SEC (or, if
     the filing is not permitted under the Exchange Act, with the trustee)
     before the incurrence of the additional Indebtedness, and

  .  the purchase price of any real estate assets or mortgages receivable
     acquired and the amount of any securities offering proceeds received (to
     the extent that the proceeds were not used to acquire real estate assets
     or mortgages receivable or used to reduce Indebtedness) by us or any of
     our Subsidiaries since the end of the calendar quarter, including those
     proceeds obtained in connection with the incurrence of the additional
     Indebtedness.

  Total Unencumbered Assets to Unsecured Debt Ratio Covenant

   We and our Subsidiaries will not be permitted at any time to own Total
Unencumbered Assets (as defined below) equal to less than 150% of the aggregate
outstanding principal amount of our and our Subsidiaries' Unsecured
Indebtedness (as defined below) on a consolidated basis.

  Debt Service Coverage Ratio Covenant

   Neither we nor any of our Subsidiaries will be permitted to incur any
Indebtedness if the ratio of Consolidated Income Available for Debt Service (as
defined below) to the Annual Service Charge (as defined below) for the four
consecutive fiscal quarters most recently ended before the date on which the
additional Indebtedness is to be incurred shall have been less than 1.5:1 on a
pro forma basis after giving effect thereto and to the application of the
proceeds therefrom, and calculated on the assumption that:

  .  the Indebtedness and any other Indebtedness incurred by us and our
     Subsidiaries since the first day of the four-quarter period and the
     application of the proceeds therefrom, including Indebtedness to refinance

                                      S-6



     other Indebtedness, had occurred at the beginning of the period, the
     repayment or retirement of any other Indebtedness by us and our
     Subsidiaries since the first day of the four-quarter period had been
     repaid or retired at the beginning of that period (except that, in making
     the computation, the amount of Indebtedness under any revolving credit
     facility is to be computed based upon the average daily balance of the
     Indebtedness during that period),

  .  in the case of Acquired Indebtedness (as defined below) or Indebtedness
     incurred in connection with any acquisition since the first day of the
     four-quarter period, the related acquisition had occurred as of the first
     day of the period with the appropriate adjustments with respect to the
     acquisition being included in the pro forma calculation, and

  .  in the case of any acquisition or disposition by us or any of our
     Subsidiaries of any asset or group of assets since the first day of the
     four-quarter period, whether by merger, stock purchase or sale, or asset
     purchase or sale, the acquisition or disposition and any related repayment
     of Indebtedness had occurred as of the first day of the period with the
     appropriate adjustments with respect to the acquisition or disposition
     being included in the pro forma calculation.

an initial holding period) the right to have such equity interests redeemed for

Encumbrance upon any of our or any Subsidiaries' properties.

Global Securities

   Rather than issue the notes in the form of physical certificates, we will
generally issue the notes in book-entry form evidenced by one or more global
securities. We anticipate that any global securities will be deposited with, or
on behalf of, The Depository Trust Company, or "DTC," and registered in the
name of Cede & Co., as DTC's nominee.

   DTC holds securities for its participants to facilitate the clearance and
settlement of securities transactions, such as transfers and pledges, among
participants through electronic book-entry changes to accounts of its
participants, thereby eliminating the need for physical movement of securities
certificates. Participants include securities brokers and dealers, banks, trust
companies, clearing corporations and other organizations. Some of the
participants, or their representatives, together with other entities, own DTC.

   Purchases of notes under the DTC system must be made by or through
participants, which will receive a credit for the notes on DTC's records.
Holders who are DTC participants may hold their interests in global securities
directly through DTC. Holders who are not DTC participants may beneficially own
interests in a global security held by DTC only through DTC participants, or
through banks, brokers, dealers, trust companies and other parties that clear
through or maintain a custodial relationship with a participant and have
indirect access to the DTC system. The ownership interest of each actual
purchaser is recorded on the participant's and indirect participants' records.
Purchasers will not receive written confirmation from DTC of their purchase,
but should 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 purchasers entered into the transaction.

   So long as Cede & Co. is the registered owner of any global security, Cede &
Co. for all purposes will be considered the sole holder of the global security.
The deposit of notes with DTC and their registration in the name of Cede & Co.
will not change the beneficial ownership of the notes. DTC has no knowledge of
the actual beneficial owners of the notes. DTC's records reflect only the
identity of the participants to whose accounts the notes are credited, which
may or may not be the beneficial owners. The participants are responsible for
keeping account of their holdings on behalf of their customers.

   Neither DTC nor Cede & Co. consents or votes with respect to the notes.
Under its usual procedures, DTC mails a proxy to the issuer as soon as possible
after the record date. The proxy assigns Cede & Co.'s consenting or voting
rights to the participants whose accounts are credited with the notes on the
record date. DTC has advised us that it will take any action permitted to be
taken by a holder of notes only at the direction of participants whose accounts
are credited with DTC interests in the relevant global security.

                                      S-9



   Unless our use of the book-entry system is discontinued, owners of
beneficial interests in a global security will not be entitled to have
certificates registered in their names, will not receive or be entitled to
receive physical delivery of certificates in definitive form, and will not be
considered the holders of the global security. The laws of some jurisdictions
require that some purchasers of securities take physical delivery of securities
in definitive form. These laws may impair the ability of those holders to
transfer their beneficial interests in the global security.

   The global securities will be exchangeable for certificated notes only if:

  .  we, in our sole discretion, elect to do so,

  .  DTC is unwilling or unable to continue as depository and a successor
     depository is not appointed by us within 90 days, or

  .  an event of default has occurred and is continuing with respect to any
     series of notes and beneficial owners representing a majority in aggregate
     principal amount of that series advises DTC to cease acting as depository.

   In any of the foregoing events, certificates for the notes will be printed
and delivered in exchange for interests in the global security. Any global
security that is so exchanged will be exchanged for notes of equal terms and
rank, in authorized denominations and registered as directed by DTC. We expect
that DTC's instruction will be based upon directions received by DTC from its
participants with respect to ownership of beneficial interests in the global
security.

   Delivery of notices and other communications by DTC to participants, by
participants to indirect participants and by 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 will be sent to Cede & Co. If less than all of the
principal amount of the global securities of the same series is being redeemed,
DTC's practice is to determine by lot the amount of the interest of each
participant in the global securities to be redeemed.

   Principal, Make-Whole Amounts and interest payments on the notes will be
made to Cede & Co. by wire transfer of immediately available funds. DTC's
practice is to credit participants' accounts on the payment date in accordance
with their respective holdings shown on DTC's records unless DTC believes that
it will not receive payment on the payment date. 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 a "street name," and will be the responsibility of
the participants and indirect participants.

   DTC has advised us that it is a limited purpose trust company organized
under the New York Banking Law, a "banking organization" within the meaning of
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
Exchange Act.

   The information in this section concerning DTC and DTC's book-entry system
has been obtained from sources that we believe to be reliable, but we are not
responsible for its accuracy. The rules applicable to DTC and its participants
are on file with the SEC. Neither we nor any trustee, registrar or paying agent
are responsible for the performance by DTC or their participants or indirect
participants under the rules and procedures governing their operations or for
any aspect of the records relating to or payments made on account of beneficial
ownership interests in the global securities or for maintaining, supervising or
reviewing any records relating to beneficial ownership interests.

Book Entry Registration for Cross-Market Transfers

   DTC will act as securities depository for all of the notes. Any transfers of
the notes to holders outside of the United States will be effected through DTC
on behalf of Euroclear Bank S.A./N.V., as operator of the Euroclear

                                     S-10



System, or "Euroclear," or Clearstream Banking, societe anonyme, or
"Clearstream Luxembourg," as participants in DTC, in accordance with the rules
of DTC. However, such cross-market transfers will require delivery of
instructions to Euroclear or Clearstream Luxembourg, as the case may be, by the
counterparty in such system in accordance with its rules and procedures and
within its established deadlines. Euroclear or Clearstream Luxembourg, as the
case may be, will, if the transfer meets its settlement requirements, deliver
instructions to its respective depository to take action to effect final
settlement on its behalf by delivering or receiving the beneficial interests in
the applicable global certificate in DTC, and making or receiving payment in
accordance with normal procedures for same-day funds settlement applicable to
DTC. Participants of Euroclear or Clearstream Luxembourg may not deliver
instructions directly to the depositories for Euroclear or Clearstream
Luxembourg, as the case may be.

   Because of time zone differences, the securities account of a Euroclear or
Clearstream Luxembourg participant purchasing a beneficial interest in a global
certificate from a DTC participant will be credited during the securities
settlement processing day (which must be a business day for Euroclear or
Clearstream Luxembourg, as applicable) immediately following the DTC settlement
date. Credit of such transfer of a beneficial interest in a global security
settled during such processing day will be reported to the applicable Euroclear
or Clearstream Luxembourg participant on that day. Cash received in Euroclear
or Clearstream Luxembourg as a result of a transfer of a beneficial interest in
a global security by or through a Euroclear or Clearstream Luxembourg
participant to a DTC participant will be received with value on the DTC
settlement date but will be available in the applicable Euroclear or
Clearstream Luxembourg cash account only as of the business day following
settlement in DTC.

   The information set out below in connection with DTC, Euroclear and
Clearstream Luxembourg is subject to any change in or reinterpretation of the
rules, regulations and procedures of the clearing systems currently in effect.
The information about each of them set forth below has been obtained from
sources that we believe to be reliable, but neither we nor any placement agent
takes any responsibility for the accuracy or completeness of the information.
Neither we nor any placement agent will have any responsibility or liability
for any aspect of the records relating to, or payments made on account of,
beneficial ownership interests in the notes held through the facilities of any
clearing system or for maintaining, supervising or reviewing any records
relating to such beneficial ownership interests.

   Although DTC, Euroclear and Clearstream Luxembourg have agreed to the
following procedures described in this section, in order to facilitate
transfers of interests in the notes among participants of DTC, Euroclear and
Clearstream Luxembourg, they are under no obligation to perform or continue to
perform such procedures, and such procedures may be discontinued at any time.
Neither we nor any placement agent assumes any responsibility for the
performance by DTC, Euroclear or Clearstream Luxembourg or their respective
participants or indirect participants of their respective obligations under the
rules and procedures governing their operations.

   DTC, Euroclear and Clearstream Luxembourg have advised us as follows:

   DTC.  DTC is a limited-purpose trust company organized under the New York
Banking Law, a "banking organization" within the meaning of 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 Exchange
Act. DTC was created to hold securities for DTC participants and to facilitate
the clearance and settlement of transactions between DTC participants through
electronic book-entry changes in accounts of DTC participants, thereby
eliminating the need for physical movement of notes. DTC participants include
the placement agents and other securities brokers and dealers, banks, trust
companies, clearing corporations and may in the future include certain other
organizations ("DTC participants"). Indirect access to the DTC system is also
available to other such banks, brokers, dealers and trust companies that clear
through or maintain a custodial relationship with a DTC participant, either
directly or indirectly ("indirect DTC participants"). DTC is owned by a number
of its participants and by the New York Stock Exchange, the American Stock
Exchange and the National Association of Securities Dealers, and rules
applicable to DTC and its participants are on file with the SEC.

                                     S-11



   Transfers of ownership or other interests in the notes in DTC may be made
only through DTC participants. Indirect DTC participants are required to effect
transfers through a DTC participant. DTC has no knowledge of the actual
beneficial owners of the notes. DTC's records reflect only the identity of the
DTC participants to whose accounts the notes are credited, which may not be the
beneficial owners. DTC participants will remain responsible for keeping account
of their holdings on behalf of their customers and for forwarding all notices
concerning the notes to their customers.

   So long as DTC, or its nominee, is the holder of a global security, payments
on a global security will be made in immediately available funds to DTC. DTC's
practice is to credit DTC participants' accounts on the applicable payment date
in accordance with their respective holdings shown on its records, unless DTC
has reason to believe that it will not receive payment on that date. Payments
by DTC participants to beneficial owners will be governed by standing
instructions and customary practices, as in the case with securities held for
the accounts of customers in bearer form or registered in "street name," and
will be the responsibility of the DTC participants and not of DTC or any other
party, subject to any statutory or regulatory requirements as may be in effect
from time to time. Payment to DTC is the responsibility of the trustee.
Disbursement of payments to DTC participants will be DTC's responsibility and
disbursement of payments to the beneficial owners will be the responsibility of
DTC participants and indirect DTC participants.

   Because DTC can only act on behalf of DTC participants, who in turn act on
behalf of indirect DTC participants, and because owners of beneficial interests
in the global notes will hold their interests through DTC participants or
indirect DTC participants, the ability of the owners of beneficial interests in
a global certificate to pledge their interests to persons or entities that do
not participate in DTC, or otherwise take actions with respect to their
interests, may be limited.

   Ownership of interests in the global securities will be shown on, and the
transfer of those ownership interests will be effected only through, records
maintained by DTC, the DTC participants and the indirect DTC participants. The
laws of some jurisdictions require that certain persons take physical delivery
in certificated form of securities which they own. Consequently, the ability to
transfer beneficial interests in the global securities is limited to such
extent.

   According to DTC, the foregoing information with respect to DTC has been
provided to the industry for informational purposes only and is not intended to
serve as a representation, warranty or contract modification of any kind.

   Euroclear.  Euroclear was created in 1968 to hold securities for Euroclear
participants (as defined below) and to clear and settle transactions between
Euroclear participants through simultaneous electronic book-entry delivery
against payment, thereby eliminating the need for physical movement of notes
and any risk from lack of simultaneous transfers of securities and cash.
Euroclear includes various other services, including securities lending and
borrowing and interfaces with domestic markets in several countries. Euroclear
is operated by the Euroclear Bank S.A./N.V. (the "Euroclear operator"), under
contract with Euroclear Clearance Systems S.C., a Belgium cooperative
corporation (the "cooperative"). All operations are conducted by the Euroclear
operator, and all Euroclear securities clearance accounts and Euroclear cash
accounts are accounts with the Euroclear operator, not the cooperative. The
cooperative establishes policy for Euroclear on behalf of Euroclear
participants. Euroclear participants include banks (including central banks),
securities brokers and dealers and other professional financial intermediaries
and may include affiliates of the placement agents and their respective
affiliates ("Euroclear participants"). Indirect access to Euroclear is also
available to other firms that clear through or maintain a custodial
relationship with a Euroclear participant, either directly or indirectly.

   Securities clearance accounts and cash accounts with the Euroclear operator
are governed by the Terms and Conditions Governing Use of Euroclear and the
related Operating Procedures of the Euroclear System, and applicable Belgian
law (collectively, the "Euroclear terms and conditions"). The Euroclear terms
and conditions govern transfers of securities and cash within Euroclear,
withdrawals of securities and cash from Euroclear and receipts of payment with
respect to securities in Euroclear. All securities in Euroclear are held on a
fungible basis

                                     S-12



without attribution of specific notes to specific securities clearance
accounts. The Euroclear operator acts under the Euroclear terms and conditions
only on behalf of Euroclear participants and has no record of or relationship
with persons holding through Euroclear participants.

   Payments with respect to notes held beneficially through Euroclear will be
credited to the cash accounts of Euroclear participants in accordance with the
Euroclear terms and conditions, to the extent received by the Euroclear
operator and by Euroclear.

   Clearstream Luxembourg.  Clearstream Luxembourg is incorporated under the
laws of Luxembourg as a professional depositary. Clearstream Luxembourg holds
securities for Clearstream Luxembourg participants (as defined below) and
facilitates the clearance and settlement of securities transactions between
Clearstream Luxembourg participants through electronic book-entry changes in
accounts of Clearstream Luxembourg participants, thereby eliminating the need
for physical movement of notes. Clearstream Luxembourg provides to Clearstream
Luxembourg participants, among other things, services for safekeeping,
administration, clearance and settlement of internationally traded securities
and securities lending and borrowing. Clearstream Luxembourg interfaces with
domestic markets in several countries. As a professional depositary,
Clearstream Luxembourg is subject to regulation by the Luxembourg Monetary
Institute. Clearstream Luxembourg participants are recognized financial
institutions around the world, including affiliates of the placement agents and
other securities brokers and dealers, banks, trust companies, clearing
corporations and certain other organizations ("Clearstream Luxembourg
participants"). Indirect access to Clearstream Luxembourg is also available to
others, such as banks, brokers, dealers and trust companies that clear through
or maintain a custodial relationship with a Clearstream Luxembourg participant
either directly or indirectly.

   Payments with respect to notes held beneficially through Clearstream
Luxembourg will be credited to cash accounts of Clearstream Luxembourg
participants in accordance with its rules and procedures, to the extent
received by Clearstream Luxembourg.

   Trading.  Except for trades involving Euroclear and Clearstream Luxembourg
participants, beneficial interests in the notes will trade in DTC's Same-Day
Funds Settlement System, and secondary market trading activity in the notes
will therefore settle in immediately available funds, subject in all cases to
the rules and operating procedures of DTC. Transfers between participants in
DTC will be effected in the ordinary way in accordance with DTC's rules and
operating procedures and will be settled in immediately available funds, while
transfers between participants in Euroclear and Clearstream Luxembourg will be
effected in the ordinary way in accordance with their respective rules and
operating procedures.

                                 RISK FACTORS

   In addition to the other information in this prospectus and the information
incorporated by reference herein, you should consider carefully the following
risk factors in evaluating an investment in our securities.

Our Performance is Subject to Risks Associated with Real Estate Investment

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

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

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

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

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

  .  Tenant Risk.  Our performance depends on our ability to collect rent from
     our tenants. While no tenant in our portfolio accounted for more than 5%
     of our annualized base rent as of September 30, 2001, our financial
     position may be adversely affected by financial difficulties experienced
     by a major tenant, or by a number of smaller tenants, including
     bankruptcies, insolvencies or general downturns in business.

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

                                      2



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

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

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

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

New Developments and Acquisitions May Fail to Perform As Expected

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

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

We Do Not Have Exclusive Control Over Our Joint Venture Investments

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

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

  .  Possibility that our co-venturer or partner might:

    .  become bankrupt;

    .  have interests or goals that are inconsistent with ours;

    .  take action contrary to our instructions, requests or interests
       (including those related to our qualification as a REIT for tax
       purposes); or

    .  otherwise impede our objectives.

Our Use of Debt Subjects Us to Various Financing Risks

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

  .  No Limitation on Debt Incurrence.  Our organizational documents do not
     limit the amount of debt we can incur. Our degree of leverage could have
     important consequences, including making it more difficult

                                      3



     for us to obtain additional financing in the future for business needs, as
     well as making us more vulnerable to an economic downturn.

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

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

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

  .  Variable Interest Rates Could Increase the Cost of Borrowing.  A
     significant amount of our financing is through an unsecured line of
     credit. The line of credit is subject to variable floating interest rates.
     Because we have not hedged against interest fluctuations, significant
     increases in interest rates could dramatically increase our costs of
     borrowing on the line of credit. Additionally, interest rates on certain
     of our debt are based on the credit rating of our debt by independent
     agencies, and would be increased in the event that the credit ratings are
     downgraded.

Our Business Structure Has Certain Risks Associated With It

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

  .  We May Not Be Able to Sell Properties When Appropriate.  Real estate
     property investments generally cannot be sold quickly. Agreements that we
     have entered into with respect to certain properties owned by CarrAmerica
     Realty, L.P. and Carr Realty, L.P. limit our ability to dispose of
     property. Also, the tax laws applicable to REITs restrict our ability to
     dispose of properties. Therefore, we may be unable to vary our portfolio
     promptly in response to market conditions, which may adversely affect our
     financial position.

  .  Lack of Voting Control Over Carr Real Estate Services, Inc.  While most of
     our income is generated from the ownership and operation of our office
     buildings, we own an 8.1% voting and 95.8% nonvoting interest in Carr Real
     Estate Services, Inc., which produces a significant contribution to our
     income. Carr

                                      4



     Real Estate Services, Inc. conducts management and leasing operations for
     third parties and for office buildings in which we own less than a 100%
     interest. As of September 30, 2001, we owned approximately 95% of the
     economic interest in Carr Real Estate Services, Inc. through the ownership
     of nonvoting common stock. The voting common stock of Carr Real Estate
     Services, Inc. is owned by The Oliver Carr Company. As a result, we have
     no right to elect the directors of Carr Real Estate Services, Inc., and
     our ability to influence its operations is limited. Carr Real Estate
     Services, Inc. may engage in business activities that are not in our best
     interests.

  .  We Depend On External Capital.  To qualify as a REIT, we generally must
     distribute to our stockholders each year at least 90% of our net taxable
     income excluding net capital gains. Because of this distribution
     requirement, we likely will not be able to fund all future capital needs,
     including capital for property development and acquisitions, with income
     from operations. We therefore will have to rely on third-party sources of
     capital, which may or may not be available on favorable terms, if at all.
     Our access to third-party sources of capital depends on a number of
     things, including the market's perception of our growth potential and our
     current and potential future earnings.

Certain Factors May Inhibit Changes in Control of the Company

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

  .  Ownership Limit.  In order to assist us in maintaining our qualification
     as a REIT and for other strategic reasons, our charter contains certain
     provisions generally limiting the ownership of shares of capital stock by
     any single stockholder to 5% of our outstanding common stock and/or 5% of
     any class or series of preferred stock. In accordance with the terms of
     our charter, our board of directors has increased these ownership limits
     to 9.8% from 5%. The federal tax laws include complex stock ownership and
     attribution rules that apply in determining whether a stockholder exceeds
     the ownership limits. These rules may cause a stockholder to be treated as
     owning capital stock that is actually owned by others, including family
     members and entities in which the stockholder has an ownership interest.
     Our board of directors could waive this restriction if it were satisfied
     that ownership in excess of these ownership limits would not jeopardize
     our status as a REIT and the board otherwise decided that a waiver would
     be in our interests. Capital stock acquired or transferred in breach of
     the ownership limit will be automatically transferred to a trust for the
     benefit of a designated charitable beneficiary.

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

                                      5



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

   As with any public company, a number of factors may adversely influence the
price of our common stock, many of which are beyond our control. These factors
include:

  .  Level of institutional interest in us;

  .  Perception of REITs generally and REITs with portfolios similar to ours,
     in particular, by market professionals;

  .  Attractiveness of securities of REITs in comparison to other companies;

  .  Our financial condition and performance;

  .  The market's perception of our growth potential and potential future cash
     dividends;

  .  Increases in market interest rates, which may lead investors to demand a
     higher annual yield from our distributions in relation to the price paid
     for our stock; and

  .  Relatively low trading volume of shares of REITs in general, which tends
     to exacerbate a market trend with respect to our stock.

   Sales of a substantial number of shares of our stock, or the perception that
such sales could occur, also could adversely affect prevailing market prices
for our common stock. In addition to the possibility that we may sell shares of
our stock in a public offering at any time, we also may issue shares of common
stock upon redemption of units of interest held by third parties in affiliated
partnerships that we control, as well as upon exercise of stock options that we
grant to our employees and others. All of these shares will be available for
sale in the public markets from time to time.

Our Status As a REIT

   We believe that we qualify for taxation as a REIT for federal income tax
purposes, and we plan to operate so that we can continue to meet the
requirements for taxation as a REIT. If we qualify as a REIT, we generally will
not be subject to federal income tax on our income that we distribute currently
to our stockholders. Many of the REIT requirements, however, are highly
technical and complex. The determination that we are a REIT requires an
analysis of various factual matters and circumstances, some of which may not be
totally within our control and some of which involve questions of
interpretation. For example, to qualify as a REIT, at least 95% of our gross
income must come from specific passive sources, like rent, that are itemized in
the REIT tax laws. In determining that we have satisfied this requirement, we
have concluded that certain services, such as cafeteria services that we have
provided to tenants through an independent contractor in certain of our
properties under arrangements where we bear part or all of the expenses of such
services, are considered customary in the geographic area where such properties
are located. There can be no assurance that the IRS or a court would agree with
such conclusion or other positions we have taken in interpreting the REIT
requirements. We also are required to distribute to our stockholders at least
90% of our REIT taxable income (excluding capital gains). The fact that we hold
some of our assets through partnerships and their subsidiaries further
complicates the application of the REIT requirements. Even a technical or
inadvertent mistake could jeopardize our REIT status. Furthermore, Congress and
the IRS might make changes to the tax laws and regulations, and the courts
might issue new rulings, that make it more difficult, or impossible, for us to
remain qualified as a REIT.

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

   Even if we qualify as a REIT for federal income tax purposes, we are
required to pay certain federal, state and local taxes on our income and
property. For example, if we have net income from "prohibited transactions,"

                                      6



that income will be subject to a 100% tax. In general, prohibited transactions
are sales or other dispositions of property held primarily for sale to
customers in the ordinary course of business. The determination as to whether a
particular sale is a prohibited transaction depends on the facts and
circumstances related to that sale. While we have undertaken a significant
number of asset sales in recent years, we do not believe that those sales
should be considered prohibited transactions, but there can be no assurance
that the IRS would not contend otherwise. In addition, any net taxable income
earned directly by our taxable affiliates, including Carr Real Estate Services,
Inc. and CarrAmerica Development, Inc., is subject to federal and state
corporate income tax. To the extent that we and our affiliates are required to
pay federal, state and local taxes, we will have less cash available for
distributions to our stockholders.

   Prior to December 31, 2000, a REIT could not own securities in any one
issuer if the value of those securities exceeded 5% of the value of the REIT's
total assets or the securities owned by the REIT represented more than 10% of
the issuer's outstanding voting securities. As a result of the REIT
Modernization Act, after December 31, 2000, the 5% value test and the 10%
voting security test were modified in two respects. First, the 10% voting
securities test was expanded so that REITs also are prohibited from owning more
than 10% of the value of the outstanding securities of any one issuer. Second,
an exception to these tests allows a REIT to own securities of a subsidiary
that exceed the 5% value test and the new 10% vote or value test if the
subsidiary elects to be a "taxable REIT subsidiary." Under a new asset test,
for taxable years beginning after December 31, 2000, we are not able to own
securities of taxable REIT subsidiaries that represent in the aggregate more
than 20% of the value of our total assets.

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

   We currently own more than 10% of the total value of the outstanding
securities of HQ Global Holdings Inc., Carr Real Estate Services, Inc. and
CarrAmerica Development, Inc. These entities have elected to be taxable REIT
subsidiaries.

Risks Associated with Debt Securities

  .  Absence of Existing Public Market for the Notes on Resale.  Prior to an
     offering of debt securities, there may have been no trading market for the
     debt securities. Any market making activity in the debt securities will be
     subject to the limits imposed by the Securities Act and the Securities
     Exchange Act of 1934, as amended (the "Exchange Act"). Accordingly, there
     can be no assurance that any market for the debt securities will develop
     or, if one does develop, that it will be maintained. If an active market
     for the debt securities fails to develop or be sustained, the trading
     price of the debt securities could be materially adversely affected.

  .  Effective Subordination of Notes.  We derive a significant portion of our
     operating income from our subsidiaries. The holders of the debt securities
     will have no direct claim against the subsidiaries (except any guarantor)
     for payment under the debt securities. We must rely to a significant
     extent on dividends and other payments from our subsidiaries (or must
     raise funds in public or private equity or debt offerings or sell assets)
     to generate the funds necessary to meet our obligations, including the
     payment of principal and interest on the debt securities. If the dividends
     and other payments from our subsidiaries were insufficient to meet such
     obligations, there could be no assurance that our operating income would
     be sufficient to meet such obligations (or that we would be able to obtain
     such funds on acceptable terms or at all).

   The debt securities will be unsecured and will be effectively subordinated
to any of our secured indebtedness to the value of the assets securing such
indebtedness. As of September 30, 2001, on a pro forma

                                      7



basis, our and our subsidiaries' total secured indebtedness was approximately
$522.2 million. The indenture permits us and our subsidiaries to incur
additional secured indebtedness provided certain conditions are met. See
"Description of the Notes--Certain Covenants." Consequently, in the event of a
bankruptcy, liquidation, dissolution, reorganization or similar proceeding with
respect to us, the holders of any secured indebtedness will be entitled to
proceed against the collateral that secures such secured indebtedness and such
collateral will not be available for satisfaction of any amounts owed under our
unsecured indebtedness, including the debt securities.

   The guarantee of the debt securities by the Guarantor is an unsecured
obligation of the Guarantor, and is effectively subordinated to mortgage and
other secured indebtedness of the Guarantor and ranks equally the Guarantor's
other unsecured and unsubordinated indebtedness.

                                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 of
additional office properties or the development of 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.

   The ratios of earnings to fixed charges were computed by dividing earnings
by fixed charges. For this purpose, earnings consist of income from continuing
operations before income taxes and minority interests plus fixed charges
(excluding interest cost capitalized) and the amortization of capitalized
interest. Fixed charges consist of interest expense (including interest costs
capitalized) and the amortization of debt issuance costs.

   We issued preferred stock in 1996 and in August, November and December 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 and in an officers' certificate 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 below under "--Ranking."

   If so provided in an applicable Prospectus Supplement, the Debt Securities
will have the benefit of a guarantee from the Guarantor. See "--Guarantee"
below. The Guarantor is a separate and distinct legal entity from the Company
and has no obligation, contingent or otherwise, to pay any amounts due pursuant
to the Debt Securities or to make any funds available therefor, whether by
dividends, loans or other payments, other than as expressly provided in a
guarantee. The payment of dividends or the making of loans and advances to the
Company by the Guarantor may be subject to contractual, statutory or regulatory
restrictions, which, if material, would be disclosed in the applicable
Prospectus Supplement. Moreover, the payment of dividends and making of loans
and advances would be contingent upon the earnings of the Guarantor. Any right
of the Company to receive assets of the Guarantor upon liquidation or
recapitalization of the Guarantor (and the consequent right of the holders of
Debt Securities to participate in those assets) will be subject to the claims
of the Guarantor's creditors. In the event that the Company is recognized as a
creditor of the Guarantor, the Company's claims would still be subject to any
security interest in the assets of the Guarantor and any indebtedness of the
Guarantor senior to that of the Debt Securities, and would be dependent
primarily upon the receipt of funds from the Guarantor.

   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

                                      10



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, including:

   (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

   (4) If convertible in whole or in part into Common Stock or Preferred Stock,

       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;

       which such rate or rates shall be determined, at which such Debt
       Securities will bear interest, if any;

       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 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;

                                      11



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

  (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;

  (18) If such Debt Securities are to be issued upon the exercise of Debt
       Warrants, the time, manner and place for such Debt Securities to be
       authenticated and delivered;

  (19) Whether and the extent to which such Debt Securities are guaranteed by
       the Guarantor and the form of any such guarantee; and

  (20) 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

                                      12



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 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, or sell, lease or convey all
or substantially all of its assets to, or merge with or into, any other entity
provided that (1) 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, 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; (2) immediately after giving effect to such
transaction and treating any indebtedness that becomes an obligation of the
Company or any Subsidiary (as defined below) 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 (3) 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.

                                      13



   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 and its Subsidiaries shall not be prevented from
selling or otherwise disposing for value its properties in the ordinary course
of business.

   Insurance.  The Company will be required to, and will be required to cause
each of its Subsidiaries to keep all of its insurable properties insured
against loss or damage to an extent that is commercially reasonable
(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
delinquent, (i) all taxes, assessments and governmental charges levied or
imposed upon it or any Subsidiary or upon the income, profits or property of
the Company or any Subsidiary, and (ii) all lawful claims for labor, materials
and supplies which, if unpaid, might by law become a lien upon the property of
the Company or any Subsidiary; provided, however, that the Company shall not be
required to pay or discharge or cause to be paid or discharged any such tax,
assessment, charge or claim whose amount, applicability or validity is being
contested in good faith by appropriate proceedings (Section 1009).

   Provision of Financial Information.  Whether or not the Company is subject
to Section 13 or 15(d) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), the Company will be required, to the extent permitted under
the Exchange Act, to file with the U.S. Securities and Exchange Commission (the
"Commission" or the "SEC") the annual reports, quarterly reports and other
documents which the Company would have been 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) within 15 days of each
Required Filing Date (i) transmit by mail to all Holders of Debt Securities, as
their names and addresses appear in the Security Register, without cost to such
Holders, copies of the Financial Information and (ii) file with the Trustee
copies of the Financial Information, and (y) if filing such documents by the
Company with the Commission is not permitted under the Exchange Act, promptly
upon written request and payment of the reasonable cost of duplication and
delivery, supply copies of such documents to all Holders of Debt Securities, as
their names and addresses appear on the Security Register and to any
prospective Holder (Section 1010). The Guarantor may be subject to similar
requirements to provide financial information, if the Debt Securities are
guaranteed.

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.

Guarantee

   In order to enable the Company to obtain more favorable interest rates and
other terms and conditions with respect to Debt Securities, payment of the
principal of (and any premium) and interest on offered Debt Securities may (if
so specified in the applicable Prospectus Supplement) be guaranteed by the
Guarantor. The guarantee will be an unsecured obligation of the Guarantor. The
ranking of any guarantee of the Debt Securities and the terms of the
subordination, if any, will be set forth in the applicable Prospectus
Supplement.

   The Indenture will provide that, in the event any guarantee of the Debt
Securities by the Guarantor would constitute or result in a violation of any
applicable fraudulent conveyance or similar law of any relevant

                                      14



jurisdiction, the liability of the Guarantor under such guarantee will be
reduced to the maximum amount, after giving effect to all other contingent and
fixed liabilities of such Guarantor, permissible under the applicable
fraudulent conveyance or similar law.

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 and continuance of such default for 30 days; (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 the performance, or breach, of
certain covenants or warranties on the part of the Company or a Guarantor
contained in the applicable Indenture, continued for 60 days after written
notice as provided in the applicable Indenture; (iv) default under any bond,
debenture, note or other evidence of indebtedness for money borrowed by the
Company, any Guarantor or any Subsidiary (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, any
Guarantor or any Subsidiary (including the leases) in an aggregate principal
amount in excess of $5,000,000, whether the indebtedness now exists or shall
hereafter be created, which default shall have resulted in the indebtedness
becoming or being declared due and payable prior to the date on which it would
otherwise have become due and payable, or the obligations being accelerated,
without the acceleration having been rescinded or annulled; (v) certain events
of bankruptcy, insolvency or reorganization, or court appointment of a
receiver, liquidator or trustee of the Company, a Guarantor or any Significant
Subsidiary (as defined in the Indenture and discussed below) for all or
substantially all of the property of the Company, a Guarantor or any
Significant Subsidiary; (vi) the guarantee of any Debt Security by a Guarantor
is no longer in full force and effect, other than by reason of termination of
the Indenture or release; 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 or a Guarantor.

   "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, a
Guarantor or by one or more other Subsidiaries of the Company or a Guarantor.
For the purposes of this definition, "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., CarrAmerica Development, OmniOffices or Omni UK, 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
and premium, if any, on 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

                                      15



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 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, (1) change

                                      16



the stated maturity of the principal of, or any installment of interest (or
premium, if any) on, any such Debt Security; (2) 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; (3) 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;
(4) impair the right to institute suit for the enforcement of any payment on or
with respect to any such Debt Security; (5) 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; (6) 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; or
(7) release a Guarantor from its guarantee (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: (1) to evidence
the succession of another person to the Company or a Guarantor as obligor under
such Indenture; (2) 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; (3) to add Events of
Default for the benefit of the Holders of all or any series of Debt Securities;
(4) 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; (5) 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; (6) to secure the Debt Securities; (7) 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; (8) 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; (9)
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 (10) to supplement any of the provisions of 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, (1) 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, (2) 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 (1) above), (3) 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

                                      17



security pursuant to the applicable Indenture, and (4) 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 1501). 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.

Ranking

   The terms and conditions, if any, upon which the Debt Securities and any
guarantee of the Debt Securities are subordinated to other indebtedness of the
Company and the Guarantor 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 and any guarantee, the
restrictions on payments to the Holders of such Debt Securities and guarantees
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 (or scheduled for redemption) 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

                                      18



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 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)

                                      19



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, 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.

                                      20



   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 35,000,000 shares of Preferred Stock. As
of September 30, 2001, there were 80,000 shares of Series A Cumulative
Convertible Redeemable Preferred Stock issued and outstanding (1,740,000 were
issued originally) and 8,000,000 shares of Series B Cumulative Redeemable
Preferred Stock. There were also 600,000 shares of Series C Cumulative
Redeemable Preferred Stock issued and outstanding and underlying 6,000,000
depositary shares, which are traded publicly, and 200,000 shares of Series D
Cumulative Redeemable Preferred Stock issued and outstanding and underlying
2,000,000 depositary shares which are traded publicly.

   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;

                                      21



   (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;

  (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

                                      22



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. 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

                                      23



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 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

                                      24



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 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,

                                      25



dissolution or winding up, will not be deemed to materially and adversely
affect such rights, preferences, privileges or voting powers.

   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, no holder of Preferred Stock
may own, or be deemed to own by virtue of certain attribution provisions of the
Code, more than 9.8% of any class or series of Preferred Stock and/or more than
9.8% 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.

                          DESCRIPTION OF COMMON STOCK

General

   The Company is authorized to issue 180,000,000 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. As of December 1, 2001, there were 51,801,842 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.

                                      26



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 Internal
Revenue Code of 1986, as amended, 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 REIT 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, through either actual ownership or deemed ownership by virtue
of certain attribution provisions of the Code, more than (A) 9.8% of the issued
and outstanding shares of Common Stock (the "Common Stock Ownership Limit") or
(B) 9.8% of any class or series of Preferred Stock (the "Preferred Stock
Ownership Limit"). (The Common Stock Ownership Limit and the Preferred Stock
Ownership Limit, together with the Existing Holder Limit, the Special
Shareholder Limit and the Non-U.S. Shareholder Limit, each as defined below,
are referred to collectively herein as the "Ownership Limits.") Certain
stockholders, 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, Security Capital 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 (the "Special
Shareholder Limit"). Security Capital's ownership interest may be permitted to
exceed 45% to the extent that such increase occurs as a result of stock
repurchases by the Company (as opposed to direct purchases by Security
Capital). Notwithstanding the Special Shareholder Limit, Security Capital has
entered into an agreement with the Company limiting Security Capital's
ownership interest to 9.8% (on a fully-diluted basis). Furthermore, all holders
are prohibited from acquiring any capital stock if such acquisition would cause
five or fewer beneficial owners of capital stock (determined taking into
account the relevant attribution provisions of the Code) who are treated as
"individuals" for purposes of relevant provisions of the Code to 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, 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" ("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

                                      27



controlled REIT," see "Federal Income Tax Considerations--U.S. Taxation of
Non-U.S. Stockholders and --Taxation of CarrAmerica 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's
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, 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 will have no
right to receive dividends or other distributions with respect to such shares
and will 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 will be paid by the
purported transferee 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 will 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 will 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, or (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 beneficial 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 shareholder upon demand is required to
disclose to the Company in writing such information as the Company may request
in good faith in order to confirm the Company's status as a REIT.

Registrar and Transfer Agent

   The Registrar and Transfer Agent for the Common Stock is EquiServe Trust
Company, N.A.

                            DESCRIPTION OF WARRANTS

   The Company may issue Common Stock Warrants for the purchase of Common Stock
and Debt Warrants for the purchase of Debt Securities. Such Warrants may be
issued separately or together with other Securities offered by a Prospectus
Supplement and may be attached to or detached from such Securities. Each series
of 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
following sets forth certain general terms and provisions of the Warrants
offered hereby. Further terms of the Warrants and the applicable Warrant
Agreements will be set forth in the applicable Prospectus Supplement.

   The applicable Prospectus Supplement will describe the terms of the Warrants
in respect of which this Prospectus is being delivered, including, where
applicable, the following: (1) the title; (2) the currencies in which the
Warrants are being offered; (3) the offering price or prices; (4) the number of
Warrants offered, (5) the

                                      28



Securities underlying the Warrants; (6) the date, if any, on and after which
the Warrants and any related Securities will be separately transferable; (7)
the price at which each of the Securities purchasable upon exercise of the
Warrants may be purchased; (8) the date on which the right to exercise the
Warrants shall commence and the date on which such right shall expire; (9) the
minimum or maximum number of Warrants that may be exercised at any one time;
(10) the procedures for exercise of the Warrants and the circumstances, if any,
that will cause the Warrants to be deemed to be exercised automatically; (11) a
discussion of certain federal income tax considerations; and (12) any other
terms of the 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.

   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

                                      29



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-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

                                      30



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 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.

                                      31



Charges of the Preferred Stock Depositary

   The Company will pay all transfer and other taxes and governmental charges
arising solely from the existence of the Deposit Agreement under which the
Depositary Shares are issued. In addition, the Company will pay the fees and
expenses of the Preferred Stock Depositary in connection with the performance
of its duties under the Deposit Agreement. However, holders of Depositary
Receipts will pay the fees and expenses of the 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

   The 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 the 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

   The 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 the 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 the 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 the 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 the
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 the 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 in the form of one or more
global securities (the "Global Securities"), which will be deposited with, or
on behalf of, a depositary 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 depositary 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

   The following discussion describes the material U.S. federal income tax
consequences relating to the taxation of the Company as a REIT and the
ownership and disposition of our common stock.

   Because this is a summary that is intended to address only federal income
tax consequences relating to the ownership and disposition of our common stock
that will apply to all holders, it may not contain all the information that may
be important to you. As you review this discussion, you should keep in mind
that:

  .  the tax consequences to you may vary depending on your particular tax
     situation;

  .  special rules that are not discussed below may apply to you if, for
     example, you are a tax-exempt organization, a broker-dealer, a non-U.S.
     person, a trust, an estate, a regulated investment company, a financial
     institution, an insurance company, or otherwise subject to special tax
     treatment under the Internal Revenue Code;

  .  this summary does not address state, local or non-U.S. tax considerations;

  .  this summary deals only with CarrAmerica common stockholders that hold
     common stock as a "capital asset," within the meaning of Section 1221 of
     the Internal Revenue Code; and

  .  this discussion is not intended to be, and should not be construed as, tax
     advice.

   You are urged both to review the following discussion and to consult with
your own tax advisor to determine the effect of ownership and disposition of
our common stock on your individual tax situation, including any state, local
or non-U.S. tax consequences.

   The information in this section is based on the current Internal Revenue
Code, current, temporary and proposed Treasury regulations, the legislative
history of the Internal Revenue Code, current administrative interpretations
and practices of the Internal Revenue Service, including its practices and
policies as endorsed in private letter rulings, which are not binding on the
Internal Revenue Service, and existing court decisions. Future legislation,
regulations, administrative interpretations and court decisions could change
current law or adversely affect existing interpretations of current law. Any
change could apply retroactively. CarrAmerica has not obtained a ruling from
the Internal Revenue Service regarding its qualification as a REIT generally.
Thus, it is possible that the Internal Revenue Service could challenge the
statements in this discussion, which do not bind the Internal Revenue Service
or the courts, and that a court could agree with the Internal Revenue Service.

   As used in this disclosure, "CarrAmerica" refers solely to CarrAmerica
Realty Corporation.

Taxation of CarrAmerica as a REIT

   General.  CarrAmerica has elected to be taxed as a REIT under the Internal
Revenue Code. A REIT generally is not subject to federal income tax on the
income that it distributes to stockholders if it meets the applicable REIT
distribution requirements and other requirements for qualification.

   CarrAmerica believes that it is organized and has operated, and CarrAmerica
intends to continue to operate, in a manner to qualify as a REIT, but there can
be no assurance that CarrAmerica will qualify or remain qualified as a REIT.
Qualification and taxation as a REIT depend upon CarrAmerica's ability to meet,
through actual annual (or in some cases quarterly) operating results,
requirements relating to income, asset ownership, distribution levels and
diversity of share ownership, and the various other REIT qualification
requirements imposed under the Internal Revenue Code. Given the complex nature
of the REIT qualification requirements, the ongoing importance of factual
determinations and the possibility of future changes in the circumstances of
CarrAmerica, CarrAmerica cannot provide any assurance that its actual operating
results will satisfy the requirements for taxation as a REIT under the Internal
Revenue Code for any particular taxable year.

                                      33



   So long as CarrAmerica qualifies for taxation as a REIT, it generally will
not be subject to federal corporate income tax on its net income that is
distributed currently to its stockholders. This treatment substantially
eliminates "double taxation" (that is, taxation at both the corporate and
stockholder levels) that generally results from an investment in a regular
corporation. However, CarrAmerica will be subject to federal income tax as
follows:

  .  CarrAmerica will be taxed at regular corporate rates on any undistributed
     "REIT taxable income." REIT taxable income is the taxable income of the
     REIT subject to specified adjustments, including a deduction for dividends
     paid.

  .  Under some circumstances, CarrAmerica may be subject to the "alternative
     minimum tax" on its items of tax preference.

  .  If CarrAmerica has net income from the sale or other disposition of
     "foreclosure property" that is held primarily for sale to customers in the
     ordinary course of business, or other nonqualifying income from
     foreclosure property, it will be subject to tax at the highest corporate
     rate on this income.

  .  CarrAmerica's net income from "prohibited transactions" will be subject to
     a 100% tax. In general, prohibited transactions are sales or other
     dispositions of property held primarily for sale to customers in the
     ordinary course of business other than foreclosure property.

  .  If CarrAmerica fails to satisfy either the 75% gross income test or the
     95% gross income test discussed below, but nonetheless maintains its
     qualification as a REIT because other requirements are met, it will be
     subject to a tax equal to the gross income attributable to the greater of
     either (1) the amount by which 75% of its gross income exceeds the amount
     of its income qualifying under the 75% test for the taxable year or
     (2) the amount by which 90% of its gross income exceeds the amount of its
     income qualifying for the 95% income test for the taxable year, multiplied
     by a fraction intended to reflect CarrAmerica's profitability.

  .  CarrAmerica will be subject to a 4% excise tax on the excess of the
     required distribution over the sum of amounts actually distributed and
     amounts retained for which federal income tax was paid, if CarrAmerica
     fails to distribute during each calendar year at least the sum of:

    .  85% of its REIT ordinary income for the year;

    .  95% of its REIT capital gain net income for the year; and

    .  any undistributed taxable income from prior taxable years.

  .  CarrAmerica will be subject to a 100% penalty tax on some payments it
     receives (or on certain expenses deducted by a taxable REIT subsidiary) if
     arrangements among CarrAmerica, its tenants, and its taxable REIT
     subsidiaries are not comparable to similar arrangements among unrelated
     parties.

  .  If CarrAmerica were to acquire any asset from a taxable "C" corporation in
     a carry-over basis transaction, it could be liable for specified tax
     liabilities inherited from that "C" corporation with respect to that
     corporation's "built-in gain" in its assets. Built-in gain is the amount
     by which an asset's fair market value exceeds its adjusted tax basis.
     Applicable Treasury regulations, however, allow an acquiring REIT to make
     an election to avoid the recognition of gain and the imposition of
     corporate level tax with respect to a built-in gain asset acquired in a
     carry-over basis transaction from a "C" corporation unless and until the
     REIT disposes of that built-in gain asset during the 10-year period
     following its acquisition, at which time the REIT would recognize, and
     would be subject to the highest regular corporate rate of tax on, the
     built-in gain.

   Requirements for qualification as a REIT. The Internal Revenue 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,
       or by transferable certificates of beneficial interest;

                                      34



   (3) that would be taxable as a domestic corporation, but for Sections 856
       through 859 of the Internal Revenue Code;

   (4) that is neither a financial institution nor an insurance company subject
       to applicable provisions of the Internal Revenue Code;

   (5) the beneficial ownership of which is held by 100 or more persons;

   (6) during the last half of each taxable year not more than 50% in value of
       the outstanding shares of which is owned directly or indirectly by five
       or fewer individuals, as defined in the Internal Revenue Code to include
       specified entities;

   (7) that makes an election to be taxable as a REIT, or has made this
       election for a previous taxable year which has not been revoked or
       terminated, and satisfies all relevant filing and other administrative
       requirements established by the Internal Revenue Service that must be
       met to elect and maintain REIT status;

   (8) that uses a calendar year for federal income tax purposes and complies
       with the recordkeeping requirements of the Internal Revenue Code and the
       Treasury regulations promulgated thereunder; and

   (9) that meets other applicable tests, described below, regarding the nature
       of its income and assets and the amount of its distributions.

Conditions (1), (2), (3) and (4) above must be met during the entire taxable
year and condition (5) above 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. For purposes of determining stock ownership under condition (6)
above, a supplemental unemployment compensation benefits plan, a private
foundation or a portion of a trust permanently set aside or used exclusively
for charitable purposes generally are considered an individual. However, a
trust that is a qualified trust under Internal Revenue Code Section 401(a)
generally is not considered an individual, and beneficiaries of a qualified
trust are treated as holding shares of a REIT in proportion to their actuarial
interests in the trust for purposes of condition (6) above.

   CarrAmerica believes that it has issued sufficient shares of capital stock
with sufficient diversity of ownership to allow it to satisfy conditions (5)
and (6) above. In addition, CarrAmerica's Articles of Incorporation contain
restrictions regarding the transfer of shares of capital stock that are
intended to assist CarrAmerica in continuing to satisfy the share ownership
requirements described in conditions (5) and (6) above. These restrictions,
however, may not ensure that CarrAmerica will be able to satisfy these stock
ownership requirements. If CarrAmerica fails to satisfy these stock ownership
requirements, it will fail to qualify as a REIT.

   To monitor its compliance with condition (6) above, a REIT is required to
send annual letters to its stockholders requesting information regarding the
actual ownership of its capital stock. If CarrAmerica complies with the annual
letters requirement and it does not know or, exercising reasonable diligence,
would not have known of its failure to meet condition (6) above, then it will
be treated as having met condition (6) above.

   To qualify as a REIT, CarrAmerica cannot have at the end of any taxable year
any undistributed earnings and profits that are attributable to a non-REIT
taxable year. CarrAmerica has elected to be taxed as a REIT beginning in 1993,
the first year of its existence. Therefore, CarrAmerica has not had any
undistributed non-REIT earnings and profits of its own. CarrAmerica does not
believe that it has acquired any non-REIT earnings and profits from any other
sources. However, the Internal Revenue Service could determine otherwise.

   If the Internal Revenue Service did determine that CarrAmerica inherited
undistributed non-REIT earnings and profits and CarrAmerica did not distribute
the non-REIT earnings and profits by the end of that taxable year, it appears
that CarrAmerica could avoid disqualification as a REIT by using "deficiency
dividend" procedures to distribute the non-REIT earnings and profits. The
deficiency dividend procedures would require CarrAmerica to make a distribution
to stockholders, in addition to the regularly required REIT distributions,
within 90 days of the Internal Revenue Service determination. In addition,
CarrAmerica would have to pay to the Internal Revenue Service interest on 50%
of the non-REIT earnings and profits that were not distributed prior to the end
of the

                                      35



taxable year in which CarrAmerica inherited the undistributed non-REIT earnings
and profits. If, however, CarrAmerica were considered to be a "successor" under
the applicable Treasury regulations to a corporation that had failed to qualify
as a REIT at the time of its merger with CarrAmerica, CarrAmerica could fail to
qualify as a REIT and could be prevented from reelecting REIT status for up to
four years after such failure to qualify.

   Qualified REIT Subsidiaries.  If a REIT owns a corporate subsidiary that is
a "qualified REIT subsidiary," the separate existence of that subsidiary will
be disregarded for federal income tax purposes. Generally, a qualified REIT
subsidiary is a corporation, other than a taxable REIT subsidiary (discussed
below), all of the capital stock of which is owned by the REIT and that has not
elected to be a "taxable REIT subsidiary" of that REIT. All assets, liabilities
and items of income, deduction and credit of the qualified REIT subsidiary will
be treated as assets, liabilities and items of income, deduction and credit of
the REIT itself. A qualified REIT subsidiary of CarrAmerica will not be subject
to federal corporate income taxation, although it may be subject to state and
local taxation in some states.

   Taxable REIT Subsidiaries.  A "taxable REIT subsidiary" of CarrAmerica is a
corporation in which CarrAmerica directly or indirectly owns stock and that
elects, together with CarrAmerica, to be treated as a taxable REIT subsidiary
under Section 856(l) of the Internal Revenue Code. In addition, if a taxable
REIT subsidiary of CarrAmerica owns, directly or indirectly, securities
representing 35% or more of the vote or value of a subsidiary corporation, that
subsidiary will also be treated as a taxable REIT subsidiary of CarrAmerica. A
taxable REIT subsidiary is a corporation subject to federal income tax, and
state and local income tax where applicable, as a regular "C" corporation.

   Generally, a taxable REIT subsidiary can perform impermissible tenant
services without causing CarrAmerica to receive impermissible tenant services
income under the REIT income tests. However, several provisions regarding the
arrangements between a REIT and its taxable REIT subsidiaries ensure that a
taxable REIT subsidiary will be subject to an appropriate level of federal
income taxation. For example, a taxable REIT subsidiary is limited in its
ability to deduct interest payments made to CarrAmerica. In addition,
CarrAmerica will be obligated to pay a 100% penalty tax on some payments that
it receives or on certain expenses deducted by the taxable REIT subsidiary if
the economic arrangements between CarrAmerica, CarrAmerica's tenants and the
taxable REIT subsidiary are not comparable to similar arrangements among
unrelated parties.

   CarrAmerica Development, Inc., Carr Real Estate Services, Inc. and HQ Global
Holdings, Inc. are referred to as the corporate subsidiaries. Each of the
corporate subsidiaries is taxable as a regular "C" corporation and has elected,
together with CarrAmerica, to be treated as a taxable REIT subsidiary of
CarrAmerica, or is treated as a taxable REIT subsidiary under the 35%
subsidiary rule discussed above. In addition, CarrAmerica has elected, together
with several other corporations in which it owns stock, for those corporations
to be treated as taxable REIT subsidiaries.

   Ownership of partnership interests by a REIT.  A REIT that is a partner in a
partnership will be deemed to own its proportionate share of the assets of the
partnership and will be deemed to earn its proportionate share of the
partnership's income. The assets and gross income of the partnership retain the
same character in the hands of the REIT for purposes of the gross income and
asset tests applicable to REITs as described below. Thus, CarrAmerica's
proportionate share of the assets and items of income of CarrAmerica Realty,
L.P. and Carr Realty L.P., including CarrAmerica Realty, L.P. and Carr Realty
L.P.'s share of assets and items of income of any subsidiaries that are
partnerships or limited liability companies, are treated as assets and items of
income of CarrAmerica for purposes of applying the asset and income tests.
CarrAmerica has control over CarrAmerica Realty, L.P. and Carr Realty L.P. and
many of the partnership and limited liability company subsidiaries of
CarrAmerica Realty, L.P. and Carr Realty L.P. and intends to operate them in a
manner that is consistent with the requirements for qualification of
CarrAmerica as a REIT.

   Income tests applicable to REITs.  To qualify as a REIT, CarrAmerica must
satisfy two gross income tests. First, at least 75% of CarrAmerica'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

                                      36



property, including "rents from real property," gains on the disposition of
real estate, dividends paid by another REIT and interest on obligations secured
by mortgages on real property or on interests in real property, or from some
types of temporary investments. Second, at least 95% of CarrAmerica's gross
income, excluding gross income from prohibited transactions, for each taxable
year must be derived from any combination of income qualifying under the 75%
test and dividends, interest, some payments under hedging instruments and gain
from the sale or disposition of stock or securities and some hedging
instruments.

   Rents received by CarrAmerica will qualify as rents from real property in
satisfying the gross income requirements for a REIT described above only if
several conditions are met. First, the amount of rent must not be based in
whole or in part on the income or profits of any person. However, an amount
received or accrued generally will not be excluded from the term rents from
real property solely by reason of being based on a fixed percentage or
percentages of receipts or sales. Second, rents received from a "related party
tenant" will not qualify as rents from real property in satisfying the gross
income tests unless the tenant is a taxable REIT subsidiary and at least 90% of
the property is leased to unrelated tenants and the rent paid by the taxable
REIT subsidiary is substantially comparable to the rent paid by the unrelated
tenants for comparable space. A tenant is a related party tenant if the REIT,
or one or more actual or constructive owners of 10% or more of the REIT,
actually or constructively owns 10% or more of the tenant. Third, if rent
attributable to personal property, leased in connection with a lease of real
property, is greater than 15% of the total rent received under the lease, then
the portion of rent attributable to the personal property will not qualify as
rents from real property.

   Generally, for rents to qualify as rents from real property for the purpose
of satisfying the gross income tests, CarrAmerica is only allowed to provide
directly services that are "usually or customarily rendered" in connection with
the rental of real property and not otherwise considered rendered primarily for
the convenience of the tenants. If CarrAmerica provides "impermissible
services" to tenants (other than through an "independent contractor" from whom
CarrAmerica derives no revenue or through a taxable REIT subsidiary),
CarrAmerica will be considered to have derived "impermissible tenant service
income," which is deemed to be not less than 150% of CarrAmerica's direct cost
of providing the service. If the impermissible tenant service income from a
property exceeds 1% of CarrAmerica's total income from that property, then all
of the income from that property will fail to qualify as rents from real
property. If the total amount of impermissible tenant service income from a
property does not exceed 1% of CarrAmerica's total income from the property,
the services will not "taint" the other income from the property (that is, it
will not cause the rent paid by tenants of that property to fail to qualify
itself as rents from real property), but the impermissible tenant service
income will not qualify as rents from real property.

   Unless CarrAmerica determines that the resulting nonqualifying income under
any of the following situations, taken together with all other nonqualifying
income earned by CarrAmerica in the taxable year, will not jeopardize
CarrAmerica's status as a REIT, CarrAmerica does not and does not intend to:

  .  charge rent for any property that is based in whole or in part on the
     income or profits of any person, except by reason of being based on a
     fixed percentage or percentages of receipts or sales, as described above;

  .  rent any property to a related party tenant, including a taxable REIT
     subsidiary;

  .  derive rental income attributable to personal property other than personal
     property leased in connection with the lease of real property, the amount
     of which is less than 15% of the total rent received under the lease; or

  .  directly perform (or provide through a contractor that is not a qualifying
     independent contractor or a taxable REIT subsidiary) services considered
     to be noncustomary or rendered to the occupant of the property.

   CarrAmerica monitors (and intends to continue to monitor) the activities
provided at, and the nonqualifying income arising from, its properties and
believes that it has not provided services that will cause it to fail to meet
the income tests. CarrAmerica provides services and provides access to third
party service providers at some or

                                      37



all of its properties. Based upon CarrAmerica's experience in the office rental
markets where the properties are located, CarrAmerica believes that all access
to service providers and services provided to tenants by CarrAmerica (other
than through a qualified independent contractor or a taxable REIT subsidiary)
either are usually or customarily rendered in connection with the rental of
real property and not otherwise considered rendered to the occupant, or, if
considered impermissible services, will not result in an amount of
impermissible tenant service income that will cause CarrAmerica to fail to meet
the income test requirements. However, CarrAmerica cannot provide any assurance
that the Internal Revenue Service will agree with these positions.

   In this regard, at some of its properties, CarrAmerica has entered into
arrangements with third party contractors under which the third party
contractors operate food service facilities and CarrAmerica bears part or all
of the expenses incurred in connection with the operation of those facilities.
Under the applicable Treasury regulations, if the REIT bears the expenses of
the service provided by a third-party contractor, that third party will be a
qualified independent contractor only if the service is customarily provided to
tenants of buildings of a similar class in the relevant geographic area.
CarrAmerica believes that it is customary to provide food services facilities
for tenants of similar buildings in the key geographic areas in which
CarrAmerica has entered into the arrangements described above and CarrAmerica
has collected information to support those beliefs with respect to those key
geographic areas. Although the Internal Revenue Service has issued several
private letter rulings to taxpayers (including one that was issued to
CarrAmerica in 1993) approving similar economic arrangements in other arguably
analogous areas, such as parking, where it has agreed that the provision of
such facilities by landlords was customary, the Internal Revenue Service has
not published any such rulings with respect to food service facilities.
(Private letter rulings are binding on the Internal Revenue Service only with
respect to the taxpayer to which the letter ruling is issued and only with
respect to the facts addressed in that letter.) In 1998, CarrAmerica requested
a private letter ruling from the Internal Revenue Service with respect to a
proposed national arrangement with a third-party contractor to operate food
service facilities at CarrAmerica's properties across the country (including
several of those described above), on terms similar to the arrangements
described above. The Internal Revenue Service initially indicated that it was
not inclined to issue that ruling, but it then agreed to issue a different
ruling related to below-market leases to food service operators. Accordingly,
CarrAmerica withdrew its initial request.

   As stated above, CarrAmerica believes that similar food service facilities
are customarily provided to tenants of similar buildings in the key geographic
areas described above. In that regard, CarrAmerica believes that there are
substantial facts that support this position that were not developed and
provided to the Internal Revenue Service as part of the ruling process. There
can be no assurance, however, that CarrAmerica's position would be upheld by a
court in the event that the Internal Revenue Service were to challenge
CarrAmerica's position. In the event that the Internal Revenue Service were to
challenge CarrAmerica's position and a court were to determine that the food
service facilities were not customary, CarrAmerica would have impermissible
tenant service income because the third-party operators would not qualify as
independent contractors as a result of the expense-bearing arrangements. At
some properties where the food service facilities are located, the amount of
any resulting impermissible tenant service income could exceed the "de minimis"
limit described above, depending upon the actual facts relevant to the affected
properties. Depending upon which properties were determined to exceed the "de
minimis" limit, CarrAmerica could fail to satisfy the 95% gross income test for
the years 1999, 2000, and possibly 2001. In that event, the IRS could assert
that CarrAmerica fails to qualify as a REIT for one or more of those years,
although the IRS also could agree that CarrAmerica has demonstrated that any
failure to meet the 95% income test was due to reasonable cause and not willful
neglect, in which event CarrAmerica would continue to qualify as a REIT for the
years in question. If the reasonable cause exception applied and CarrAmerica
were not disqualified as a REIT, it would be required to pay some taxes based
on the amount of income that did not qualify for the 95% income test, which
CarrAmerica believes would not be material to its financial position. For a
description of the applicable tax provisions, see "--Taxation of CarrAmerica as
a REIT," above.

   "Interest" generally will be nonqualifying income for purposes of the 75% or
95% gross income tests if it depends in whole or in part on the income or
profits of any person. However, interest based on a fixed percentage

                                      38



or percentages of receipts or sales may still qualify under the gross income
tests. CarrAmerica does not expect to derive significant amounts of interest
that will not qualify under the 75% and 95% gross income tests.

   CarrAmerica's share of any dividends received from the corporate
subsidiaries (and from other corporations in which CarrAmerica owns an
interest) will qualify for purposes of the 95% gross income test but not for
purposes of the 75% gross income test. CarrAmerica does not anticipate that it
will receive sufficient dividends to cause it to exceed the limit on
nonqualifying income under the 75% gross income test.

   If CarrAmerica 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 that year
if it is entitled to relief under the Internal Revenue Code. These relief
provisions generally will be available if CarrAmerica's failure to meet the
tests is due to reasonable cause and not due to willful neglect, CarrAmerica
attaches a schedule of the sources of its income to its federal income tax
return and any incorrect information on the schedule is not due to fraud with
intent to evade tax. It is not possible, however, to state whether in all
circumstances CarrAmerica would be entitled to the benefit of these relief
provisions. For example, if CarrAmerica fails to satisfy the gross income tests
because nonqualifying income that CarrAmerica intentionally incurs exceeds the
limits on nonqualifying income, the Internal Revenue Service could conclude
that the failure to satisfy the tests was not due to reasonable cause. If these
relief provisions are inapplicable to a particular set of circumstances
involving CarrAmerica, CarrAmerica will fail to qualify as a REIT. As discussed
under "--Taxation of CarrAmerica as a REIT--General" even if these relief
provisions apply, a tax would be imposed based on the amount of nonqualifying
income.

   In addition to the 75% and 95% gross income tests, CarrAmerica had to meet a
30% gross income test for its taxable years that ended prior to January 1,
1998. The 30% gross income test required that 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,
represent less than 30% of CarrAmerica's gross income, including gross income
from prohibited transactions. The 30% gross income test is not applicable for
taxable years starting on or after January 1, 1998.

   Prohibited Transactions Tax.  Any gain realized by CarrAmerica on the sale
of any property held as inventory or other property held primarily for sale to
customers in the ordinary course of business, including CarrAmerica's share of
this type of gain realized by CarrAmerica Realty, L.P. and Carr Realty L.P. and
any other partnership or limited liability company subsidiaries, will be
treated as income from a prohibited transaction that is subject to a 100%
penalty tax. Under existing law, whether property is held as inventory or
primarily for sale to customers in the ordinary course of a trade or business
is a question of fact that depends on all the facts and circumstances of a
particular transaction. CarrAmerica intends to hold its properties for
investment with a view to long- term appreciation, to engage in the business of
acquiring, developing, owning and operating properties, and to make occasional
sales of properties as are consistent with CarrAmerica's investment objectives.
CarrAmerica cannot provide any assurance, however, that the Internal Revenue
Service might not contend that one or more of these sales are subject to the
100% penalty tax.

   Asset Tests Applicable to REITs.  At the close of each quarter of its
taxable year, CarrAmerica must satisfy four tests relating to the nature of its
assets:

   (1) at least 75% of the value of CarrAmerica's total assets must be
       represented by real estate assets, cash, cash items and government
       securities. CarrAmerica's real estate assets include, for this purpose,
       its allocable share of real estate assets held by CarrAmerica Realty,
       L.P. and Carr Realty L.P. and their partnership and limited liability
       subsidiaries, as well as stock or debt instruments held for less than
       one year purchased with the proceeds of an offering of stock or
       long-term debt of CarrAmerica;

   (2) not more than 25% of CarrAmerica's total assets may be represented by
       securities other than those in the 75% asset class;

                                      39



   (3) except for equity investments in REITs, qualified REIT subsidiaries, or
       taxable REIT subsidiaries or other securities that qualify as "real
       estate assets" for purposes of the test described in clause (1):

      .  the value of any one issuer's securities owned by CarrAmerica may not
         exceed 5% of the value of CarrAmerica's total assets;

      .  CarrAmerica may not own more than 10% of any one issuer's outstanding
         voting securities; and

      .  CarrAmerica may not own more than 10% of the value of the outstanding
         securities of any one issuer; and

   (4) not more than 20% of CarrAmerica's total assets may be represented by
       securities of one or more taxable REIT subsidiaries.

   Securities for purposes of the asset tests may include debt securities.
   However, debt of an issuer will not count as a security for purposes of the
   10% value test if the debt securities are "straight debt" as defined in
   Section 1361 of the Internal Revenue Code and (1) the issuer is an
   individual, (2) the only securities of the issuer that the REIT holds are
   straight debt or (3) if the issuer is a partnership, the REIT holds at least
   a 20% profits interest in the partnership.

   CarrAmerica believes that the aggregate value of its taxable REIT
subsidiaries does not exceed 20% of the aggregate value of its gross assets. As
of each relevant testing date prior to the election to treat each corporate
subsidiary of CarrAmerica or any other corporation in which CarrAmerica owns an
interest as a taxable REIT subsidiary, which election first became available as
of January 1, 2001, CarrAmerica believes it did not own more than 10% of the
voting securities of any such entity. In addition, CarrAmerica believes that as
of each relevant testing date prior to the election to treat each corporate
subsidiary of CarrAmerica or any other corporation in which CarrAmerica owns an
interest as a taxable REIT subsidiary of CarrAmerica, CarrAmerica's pro rata
share of the value of the securities, including debt, of any such corporation
or other issuer did not exceed 5% of the total value of CarrAmerica's assets.

   With respect to each issuer in which CarrAmerica currently owns an interest
that does not qualify as a REIT, a qualified REIT subsidiary or a taxable REIT
subsidiary, CarrAmerica believes that its pro rata share of the value of the
securities, including debt, of any such issuer does not exceed 5% of the total
value of CarrAmerica's assets and that it complies with the 10% voting
securities limitation and 10% value limitation with respect to each such
issuer. In this regard, however, CarrAmerica cannot provide any assurance that
the Internal Revenue Service might not disagree with CarrAmerica's
determinations.

   After initially meeting the asset tests at the close of any quarter,
CarrAmerica will not lose its status as a REIT if it fails to satisfy the 25%,
20%, and 5% asset tests and the 10% value limitation at the end of a later
quarter solely by reason of changes in the relative values of its assets. If
the failure to satisfy the 25%, 20%, or 5% asset tests or the 10% value
limitation results from an acquisition of securities or other property during a
quarter, the failure can be cured by disposition of sufficient nonqualifying
assets within 30 days after the close of that quarter. CarrAmerica intends to
maintain adequate records of the value of its assets to ensure compliance with
the asset tests and to take any available actions within 30 days after the
close of any quarter as may be required to cure any noncompliance with the 25%,
20%, or 5% asset tests or 10% value limitation. If CarrAmerica were to fail to
cure noncompliance with the asset tests within this time period, CarrAmerica
would cease to qualify as a REIT.

   Annual distribution requirements applicable to REITs.  To qualify as a REIT,
CarrAmerica is required to distribute dividends, other than capital gain
dividends, to its stockholders each year in an amount at least equal to (1) the
sum of (a) 90% of CarrAmerica's REIT taxable income, computed without regard to
the dividends paid deduction and its net capital gain, and (b) 90% of the net
income, after tax, from foreclosure property, minus (2) the sum of certain
specified items of noncash income. In addition, if CarrAmerica recognizes any
built-in gain, CarrAmerica will be required, under Treasury regulations, to
distribute at least 90% of the built-in gain, after tax, recognized on the
disposition of the applicable asset. See "--Taxation of CarrAmerica as a REIT--

                                      40



General" for a discussion of the possible recognition of built-in gain. These
distributions must be paid either in the taxable year to which they relate, or
in the following taxable year if declared before CarrAmerica timely files its
tax return for the prior year and if paid with or before the first regular
dividend payment date after the declaration is made.

   CarrAmerica intends to make timely distributions sufficient to satisfy its
annual distribution requirements. It is expected that CarrAmerica's REIT
taxable income generally will be less than its cash flow due to the allowance
of depreciation and other noncash charges in computing REIT taxable income.
Accordingly, CarrAmerica anticipates that it generally will have sufficient
cash or liquid assets to enable it to satisfy the distribution requirements
described above. It is possible, however, that CarrAmerica, from time to time,
may not have sufficient cash or other liquid assets to meet these distribution
requirements. In this event, CarrAmerica may find it necessary to arrange for
short-term, or possibly long-term, borrowings to fund the required
distributions.

   Under some circumstances, CarrAmerica may be able to rectify a failure to
meet the distribution requirement for a year by paying deficiency dividends to
stockholders in a later year, which may be included in CarrAmerica's deduction
for dividends paid for the earlier year. Thus, CarrAmerica may be able to avoid
being taxed on amounts distributed as deficiency dividends; however,
CarrAmerica will be required to pay interest based upon the amount of any
deduction taken for deficiency dividends.

   To the extent that CarrAmerica does not distribute all of its net capital
gain or distributes at least 90%, but less than 100%, of its REIT taxable
income, as adjusted, it is subject to tax on these amounts at regular corporate
tax rates.

   CarrAmerica will be subject to a 4% excise tax on the excess of the required
distribution over the sum of amounts actually distributed and amounts retained
for which federal income tax was paid, if CarrAmerica fails to distribute
during each calendar year at least the sum of:

   (1) 85% of its REIT ordinary income for the year;

   (2) 95% of its REIT capital gain net income for the year; and

   (3) any undistributed taxable income from prior taxable years.

   A REIT may elect to retain rather than distribute all or a portion of its
   net capital gains and pay the tax on the gains. In that case, a REIT may
   elect to have its stockholders include their proportionate share of the
   undistributed net capital gains in income as long-term capital gains and
   receive a credit for their share of the tax paid by the REIT. For purposes
   of the 4% excise tax described above, any retained amounts would be treated
   as having been distributed.

   Record-Keeping Requirements.  CarrAmerica is required to comply with
applicable record-keeping requirements. Failure to comply could result in
monetary fines. Failure of CarrAmerica to qualify as a REIT. If CarrAmerica
fails to qualify for taxation as a REIT in any taxable year, and if relief
provisions do not apply, CarrAmerica will be subject to tax, including any
applicable alternative minimum tax, on its taxable income at regular corporate
rates. If CarrAmerica fails to qualify as a REIT, CarrAmerica will not be
required to make any distributions to stockholders and any distributions that
are made to stockholders will not be deductible by CarrAmerica. As a result,
CarrAmerica's failure to qualify as a REIT would significantly reduce the cash
available for distributions by CarrAmerica to its stockholders. In addition, if
CarrAmerica fails to qualify as a REIT, all distributions to stockholders will
be taxable as ordinary income to the extent of CarrAmerica's current and
accumulated earnings and profits, whether or not attributable to capital gains
of CarrAmerica, and corporate stockholders may be eligible for the dividends
received deduction. Unless entitled to relief under specific statutory
provisions, CarrAmerica also will be disqualified from taxation as a REIT for
the four taxable years following the year during which qualification was lost.
There can be no assurance that CarrAmerica would be entitled to any statutory
relief.

                                      41



Taxation of U.S. Stockholders

   As used in the remainder of this discussion, the term "U.S. stockholder"
means a beneficial owner of CarrAmerica common stock that is, for United States
federal income tax purposes:

   (1) a citizen or resident, as defined in Section 7701(b) of the Internal
       Revenue Code, of the United States;

   (2) a corporation or partnership, or other entity treated as a corporation
       or partnership for federal income tax purposes, created or organized
       under the laws of the United States, any state or the District of
       Columbia;

   (3) an estate the income of which is subject to federal income taxation
       regardless of its source; or

   (4) in general, a trust subject to the primary supervision of a United
       States court and the control of one or more United States persons.

Generally, in the case of a partnership that holds CarrAmerica common stock,
any partner that would be a U.S. stockholder if it held the CarrAmerica common
stock directly is also a U.S. stockholder. A "non-U.S. stockholder" is a
holder, including any partner in a partnership that holds CarrAmerica common
stock, that is not a U.S. stockholder.

   Distributions by CarrAmerica.  So long as CarrAmerica qualifies as a REIT,
distributions to U.S. Stockholders out of its current or accumulated earnings
and profits that are not designated as capital gain dividends will be taxable
as ordinary income and will not be eligible for the dividends received
deduction generally available for corporations. Distributions in excess of its
current and accumulated earnings and profits will not be taxable to a U.S.
stockholder to the extent that the distributions do not exceed the adjusted tax
basis of the stockholder's stock. Rather, such distributions will reduce the
adjusted basis of such stock. Distributions that exceed the U.S. stockholder's
adjusted basis in its stock will be taxable as capital gains if the stock is
held as a capital asset. If CarrAmerica declares a dividend in October,
November, or December of any year with a record date in one of these months and
pays the dividend on or before January 31 of the following year, CarrAmerica
will be treated as having paid the dividend, and the stockholder will be
treated as having received the dividend, on December 31 of the year in which
the dividend was declared.

   CarrAmerica may elect to designate distributions of its net capital gain as
"capital gain dividends." Capital gain dividends are taxed to stockholders as
gain from the sale or exchange of a capital asset held for more than one year,
without regard to how long the U.S. stockholder has held its stock.
Designations made by CarrAmerica will be effective only to the extent that they
comply with Revenue Ruling 89-81, which requires that distributions made to
different classes of shares be composed proportionately of dividends of a
particular type. If CarrAmerica designates any portion of a dividend as a
capital gain dividend, a U.S. stockholder will receive an Internal Revenue
Service Form 1099-DIV indicating the amount that will be taxable to the
stockholder as capital gain. Corporate stockholders, however, may be required
to treat up to 20% of capital gain dividends as ordinary income.

   Instead of paying capital gain dividends, CarrAmerica may designate all or
part of its net capital gain as "undistributed capital gain." CarrAmerica will
be subject to tax at regular corporate rates on any undistributed capital gain.

   A U.S. stockholder:

   (1) will include in its income as long-term capital gains its proportionate
       share of such undistributed capital gains and

   (2) will be deemed to have paid its proportionate share of the tax paid by
       CarrAmerica on such undistributed capital gains and receive a credit or
       refund to the extent that the tax paid by CarrAmerica exceeds the U.S.
       stockholder's tax liability on the undistributed capital gain.

                                      42



   A U.S. stockholder 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 tax it is deemed to have paid. The earnings and profits of
CarrAmerica will be adjusted appropriately.

   CarrAmerica will classify portions of any designated capital gain dividend
or undistributed capital gain as either:

   (1) a 20% rate gain distribution, which would be taxable to non-corporate
       U.S. Stockholders at a maximum rate of 20%; or

   (2) an "unrecaptured Section 1250 gain" distribution, which would be taxable
       to non-corporate U.S. Stockholders at a maximum rate of 25%.

   CarrAmerica must determine the maximum amounts that it may designate as 20%
and 25% rate capital gain dividends by performing the computation required by
the Internal Revenue Code as if the REIT were an individual whose ordinary
income were subject to a marginal tax rate of at least 28%.

   Distributions made by CarrAmerica and gain arising from the sale or exchange
by a U.S. stockholder of common stock will not be treated as passive activity
income, and as a result, U.S. Stockholders generally will not be able to apply
any "passive losses" against this income or gain. In addition, taxable
distributions from CarrAmerica generally will be treated as investment income
for purposes of the investment interest limitations. A U.S. stockholder may
elect to treat capital gain dividends and capital gains from the disposition of
common stock as investment income for purposes of the investment interest
limitation, in which case the applicable capital gains will be taxed at
ordinary income rates. CarrAmerica will notify stockholders regarding the
portions of distributions for each year that constitute ordinary income, return
of capital and capital gain. U.S. stockholders may not include in their
individual income tax returns any net operating losses or capital losses of
CarrAmerica. CarrAmerica's operating or capital losses would be carried over by
CarrAmerica for potential offset against future income, subject to applicable
limitations.

   Sales of Shares.  Upon any taxable sale or other disposition of shares, a
U.S. stockholder will recognize gain or loss for federal income tax purposes in
an amount equal to the difference between:

   (1) the amount of cash and the fair market value of any property received on
       the sale or other disposition; and

   (2) the holder's adjusted basis in the shares for tax purposes.

   This gain or loss will be a capital gain or loss if the shares have been
held by the U.S. stockholder as a capital asset. The applicable tax rate will
depend on the stockholder's holding period in the asset (generally, if an asset
has been held for more than one year it will produce long-term capital gain)
and the stockholder's tax bracket. The Internal Revenue Service has the
authority to prescribe, but has not yet prescribed, regulations that would
apply a capital gain tax rate of 25% (which is generally higher than the
long-term capital gain tax rates for noncorporate stockholders) to a portion of
capital gain realized by a noncorporate stockholder on the sale of REIT shares
that would correspond to the REIT's "unrecaptured Section 1250 gain."
Stockholders are urged to consult with their own tax advisors with respect to
their capital gain tax liability. A corporate U.S. stockholder will be subject
to tax at a maximum rate of 35% on capital gain from the sale of CarrAmerica
stock held for more than 12 months. In general, any loss recognized by a U.S.
stockholder upon the sale or other disposition of shares of common stock that
have been held for six months or less, after applying the holding period rules,
will be treated as a long-term capital loss, to the extent of distributions
received by the U.S. stockholder from CarrAmerica that were required to be
treated as long-term capital gains.

Taxation of Tax-Exempt Stockholders

   Provided that a tax-exempt stockholder has not held its common stock as
"debt financed property" within the meaning of the Internal Revenue Code, the
dividend income from CarrAmerica will not be unrelated business

                                      43



taxable income, referred to as UBTI, to a tax-exempt stockholder. Similarly,
income from the sale of stock will not constitute UBTI unless the tax-exempt
stockholder has held its shares as debt financed property within the meaning of
the Internal Revenue Code or has used the stock in a trade or business.

   However, for tax-exempt stockholders that are social clubs, voluntary
employee benefit associations, supplemental unemployment benefit trusts and
qualified group legal services plans exempt from federal income taxation under
Sections 501(c)(7), (c)(9), (c)(17) and (c)(20) of the Internal Revenue Code,
respectively, income from an investment in CarrAmerica will constitute UBTI
unless the organization properly sets aside or reserves such amounts for
purposes specified in the Internal Revenue Code. These tax-exempt stockholders
should consult their own tax advisors concerning these "set aside" and reserve
requirements.

   Notwithstanding the above, however, a portion of the dividends paid by a
"pension held REIT" are treated as UBTI if received by any trust which is
described in Section 401(a) of the Internal Revenue Code, is tax-exempt under
Section 501(a) of the Internal Revenue Code, and holds more than 10%, by value,
of the interests in the REIT. Tax-exempt pension funds that are described in
Section 401(a) of the Internal Revenue Code are referred to below as "pension
trusts."

   A REIT is a pension held REIT if it meets the following two tests:

   (1) it qualified as a REIT only by reason of Section 856(h)(3) of the
       Internal Revenue Code, which provides that stock owned by pension trusts
       will be treated, for purposes of determining if the REIT is closely
       held, as owned by the beneficiaries of the trust rather than by the
       trust itself; and

   (2) either (a) at least one pension trust holds more than 25% of the value
       of the REIT's stock, or (b) a group of pension trusts each individually
       holding more than 10% of the value of the REIT's shares, collectively
       owns more than 50% of the value of the REIT's shares.

   The percentage of any REIT dividend treated as UBTI is equal to the ratio of
the UBTI earned by the REIT, treating the REIT as if it were a pension trust
and therefore subject to tax on UBTI, to the total gross income of the REIT. An
exception applies where the percentage is less than 5% for any year. The
provisions requiring pension trusts to treat a portion of REIT distributions as
UBTI will not apply if the REIT is able to satisfy the "not closely held
requirement" without relying upon the "look-through" exception with respect to
pension trusts. Based on both its current capital stock ownership and the
limitations on transfer and ownership of capital stock contained in its
Articles of Incorporation, CarrAmerica does not expect to be classified as a
pension held REIT.

U.S. Taxation of Non-U.S. Stockholders

   Distributions by CarrAmerica. Distributions by CarrAmerica to a non-U.S.
stockholder that are neither attributable to gain from sales or exchanges by
CarrAmerica of "U.S. real property interests" nor designated by CarrAmerica as
capital gains dividends will be treated as dividends of ordinary income to the
extent that they are made out of CarrAmerica's current or accumulated earnings
and profits. These distributions ordinarily will be subject to withholding of
U.S. federal income tax on a gross basis at a rate of 30%, or a lower rate as
permitted under an applicable income tax treaty, unless the dividends are
treated as effectively connected with the conduct by the non-U.S. stockholder
of a U.S. trade or business. Under some treaties, however, lower withholding
rates generally applicable to dividends do not apply to dividends from REITs.
Applicable certification and disclosure requirements must be satisfied to be
exempt from withholding under the effectively connected income exemption.
Dividends that are effectively connected with a trade or business will be
subject to tax on a net basis, that is, after allowance for deductions, at
graduated rates, in the same manner as U.S. Stockholders are taxed with respect
to these dividends, and are generally not subject to withholding. Any dividends
received by a corporate non-U.S. stockholder that is engaged in a U.S. trade or
business also may be subject to an additional branch profits tax at a 30% rate,
or lower applicable treaty rate.

   Distributions in excess of current and accumulated earnings and profits that
exceed the non-U.S. stockholder's basis in its CarrAmerica common stock will be
taxable to a non-U.S. stockholder as gain from the

                                      44



sale of common stock, which is discussed below. Distributions in excess of
current or accumulated earnings and profits of CarrAmerica that do not exceed
the adjusted basis of the non-U.S. stockholder in its common stock will reduce
the non-U.S. stockholder's adjusted basis in its common stock and will not be
subject to U.S. federal income tax, but will be subject to U.S. withholding tax
as described below.

   CarrAmerica expects to withhold U.S. income tax at the rate of 30% on any
dividend distributions (including distributions that later may be determined to
have been in excess of current and accumulated earnings and profits) made to a
non-U.S. stockholder unless:

   (1) a lower treaty rate applies and the non-U.S. stockholder files an
       Internal Revenue Service Form W-8BEN evidencing eligibility for that
       reduced treaty rate with CarrAmerica; or

   (2) the non-U.S. stockholder files an Internal Revenue Service Form W-8ECI
       with CarrAmerica claiming that the distribution is effectively connected
       income.

   CarrAmerica may be required to withhold at least 10% of any distribution in
   excess of its current and accumulated earnings and profits, even if a lower
   treaty rate applies and the non-U.S. stockholder is not liable for tax on
   the receipt of that distribution. However, a non-U.S. stockholder may seek a
   refund of these amounts from the Internal Revenue Service if the non-U.S.
   stockholder's U.S. tax liability with respect to the distribution is less
   than the amount withheld.

   Distributions to a non-U.S. stockholder that are designated by CarrAmerica
at the time of the distribution as capital gain dividends, other than those
arising from the disposition of a U.S. real property interest, generally should
not be subject to U.S. federal income taxation unless:

   (1) the investment in the common stock is effectively connected with the
       non-U.S. stockholder's U.S. trade or business, in which case the non-
       U.S. stockholder will be subject to the same treatment as U.S.
       stockholders with respect to any gain, except that a stockholder that is
       a foreign corporation also may be subject to the 30% branch profits tax,
       as discussed above, or

   (2) the non-U.S. stockholder is a nonresident alien individual who is
       present in the U.S. for 183 days or more during the taxable year and has
       a "tax home" in the U.S., in which case the nonresident alien individual
       will be subject to a 30% tax on the individual's capital gains.

   Under the Foreign Investment in Real Property Tax Act, which is referred to
as "FIRPTA," distributions to a non-U.S. stockholder that are attributable to
gain from sales or exchanges by CarrAmerica of U.S. real property interests,
whether or not designated as a capital gain dividend, will cause the non-U.S.
stockholder to be treated as recognizing gain that is income effectively
connected with a U.S. trade or business. Non-U.S. Stockholders will be taxed on
this gain at the same rates applicable to U.S. Stockholders, subject to a
special alternative minimum tax in the case of nonresident alien individuals.
Also, this gain may be subject to a 30% branch profits tax in the hands of a
non-U.S. stockholder that is a corporation.

   CarrAmerica will be required to withhold and remit to the Internal Revenue
Service 35% of any distributions to non-U.S. stockholders that are designated
as capital gain dividends, or, if greater, 35% of a distribution that could
have been designated as a capital gain dividend. Distributions can be
designated as capital gains to the extent of CarrAmerica's net capital gain for
the taxable year of the distribution. The amount withheld is creditable against
the non- U.S. stockholder's U.S. federal income tax liability.

   Although the law is not clear on the matter, it appears that amounts
designated by CarrAmerica as undistributed capital gains in respect of the
common stock held by U.S. Stockholders generally should be treated with respect
to non-U.S. stockholders in the same manner as actual distributions by
CarrAmerica of capital gain dividends. Under that approach, the non-U.S.
stockholders would be able to offset as a credit against their U.S. federal
income tax liability resulting therefrom their proportionate share of the tax
paid by CarrAmerica on the undistributed capital gains, and to receive from the
Internal Revenue Service a refund to the extent their proportionate share of
this tax paid by CarrAmerica were to exceed their actual United States federal
income tax liability.

                                      45



   Sale of Common Stock.  Gain recognized by a non-U.S. stockholder upon the
sale or exchange of CarrAmerica common stock generally would not be subject to
U.S. taxation unless:

   (1) the investment in the CarrAmerica common stock is effectively connected
       with the non-U.S. stockholder's U.S. trade or business, in which case
       the non-U.S. stockholder will be subject to the same treatment as
       domestic Stockholders with respect to any gain;

   (2) the non-U.S. stockholder is a nonresident alien individual who is
       present in the United States for 183 days or more during the taxable
       year and has a tax home in the United States, in which case the
       nonresident alien individual will be subject to a 30% tax on the
       individual's net capital gains for the taxable year; or

   (3) the CarrAmerica common stock constitute a U.S. real property interest
       within the meaning of FIRPTA, as described below.

   The CarrAmerica common stock will not constitute a United States real
property interest if CarrAmerica is a domestically controlled REIT. CarrAmerica
will be a domestically-controlled REIT if, at all times during a specified
testing period, less than 50% in value of its stock is held directly or
indirectly by non-U.S. Stockholders.

   CarrAmerica believes that, currently, it is a domestically controlled REIT
and, therefore, that the sale of CarrAmerica common stock would not be subject
to taxation under FIRPTA. In addition, CarrAmerica's charter contains ownership
limitations designed to help prevent CarrAmerica from failing to qualify as a
domestically controlled REIT. Because CarrAmerica common stock is publicly
traded, however, CarrAmerica cannot guarantee that it is or will continue to be
a domestically controlled REIT.

   Even if CarrAmerica does not qualify as a domestically-controlled REIT at
the time a non-U.S. stockholder sells its CarrAmerica common stock, gain
arising from the sale still would not be subject to FIRPTA tax if:

   (1) the class or series of stock sold is considered regularly traded under
       applicable Treasury regulations on an established securities market,
       such as the NYSE; and

   (2) the selling non-U.S. stockholder owned, actually or constructively, 5%
       or less in value of the outstanding class or series of stock being sold
       throughout the five-year period ending on the date of the sale or
       exchange.

If gain on the sale or exchange of CarrAmerica common stock were subject to
taxation under FIRPTA, the non-U.S. stockholder would be subject to regular
U.S. income tax with respect to any gain in the same manner as a taxable U.S.
stockholder, subject to any applicable alternative minimum tax and special
alternative minimum tax in the case of nonresident alien individuals.

Information Reporting and Backup Withholding Tax Applicable to Stockholders

       U.S. Stockholders.   In general, information-reporting requirements will
       apply to payments of distributions on CarrAmerica common stock and
       payments of the proceeds of the sale of CarrAmerica common stock to some
       Stockholders, unless an exception applies. Further, the payer will be
       required to withhold backup withholding tax at the rate of 30% if:

   (1) the payee fails to furnish a taxpayer identification number, or TIN, to
       the payer or to establish an exemption from backup withholding;

   (2) the Internal Revenue Service notifies the payer that the TIN furnished
       by the payee is incorrect;

   (3) there has been a notified payee under-reporting with respect to
       interest, dividends or original issue discount described in Section
       3406(c) of the Internal Revenue Code; or

   (4) there has been a failure of the payee to certify under the penalty of
       perjury that the payee is not subject to backup withholding under the
       Internal Revenue Code.

                                      46



   Some Stockholders, including corporations, will be exempt from backup
   withholding. Any amounts withheld under the backup withholding rules from a
   payment to a stockholder will be allowed as a credit against the
   stockholder's U.S. federal income tax liability and may entitle the
   stockholder to a refund, provided that the required information is furnished
   to the Internal Revenue Service.

   Non-U.S. Stockholders.  Generally, information reporting will apply to
payments of distributions on CarrAmerica common stock, and backup withholding
at a rate of 31% may apply, unless the payee certifies that it is not a U.S.
person or otherwise establishes an exemption.

   The payment of the proceeds from the disposition of CarrAmerica common stock
to or through the U.S. office of a U.S. or foreign broker will be subject to
information reporting and, possibly, backup withholding unless the non-U.S.
stockholder certifies as to its non-U.S. status or otherwise establishes an
exemption, provided that the broker does not have actual knowledge that the
stockholder is a U.S. person or that the conditions of any other exemption are
not, in fact, satisfied. The proceeds of the disposition by a non-U.S.
stockholder of CarrAmerica common stock to or through a foreign office of a
broker generally will not be subject to information reporting or backup
withholding. However, if the broker is a U.S. person, a controlled foreign
corporation for U.S. tax purposes, or a foreign person 50% or more of whose
gross income from all sources for specified periods is from activities that are
effectively connected with a U.S. trade or business, information reporting
generally will apply unless the broker has documentary evidence as to the non-
U.S. stockholder's foreign status and has no actual knowledge to the contrary.
Applicable Treasury regulations provide presumptions regarding the status of
stockholders when payments to the Stockholders cannot be reliably associated
with appropriate documentation provided to the payer. Under these Treasury
regulations, some stockholders are required to have provided new certifications
with respect to payments made after December 31, 2000. Because the application
of the these Treasury regulations varies depending on the stockholder's
particular circumstances, you are urged to consult your tax advisor regarding
the information reporting requirements applicable to you.

Tax Aspects of CarrAmerica's Ownership of Interests in Partnerships

   General.  A substantial portion of CarrAmerica's investments are held
indirectly through CarrAmerica Realty, L.P., Carr Realty, L.P., and other
partnerships and LLCs. In general, partnerships and limited liability companies
are "pass-through" entities that are not subject to federal income tax. Rather,
partners or members are allocated their proportionate shares of the items of
income, gain, loss, deduction and credit of the pass-through entity, and are
potentially subject to tax thereon, without regard to whether the partners or
members receive a distribution from the partnership. CarrAmerica includes in
its income its proportionate share of the foregoing partnership items for
purposes of the various REIT income tests and in the computation of its REIT
taxable income. Moreover, for purposes of the REIT asset tests, CarrAmerica
includes its proportionate share of assets held through CarrAmerica Realty,
L.P., Carr Realty, L.P., and other partnerships and LLCs. See "--Requirements
for Qualification as a REIT --Ownership of Partnership Interests by a REIT"
above.

   Entity Classification.  CarrAmerica believes that CarrAmerica Realty, L.P.
and Carr Realty, L.P. and each partnership in which CarrAmerica owns an
interest will be treated as a partnership for federal income tax purposes and
not as an association taxable as a corporation. CarrAmerica believes that each
LLC in which CarrAmerica owns an interest will be treated as a partnership or
disregarded for federal income tax purposes. If any of these partnerships or
LLCs 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 CarrAmerica's assets and items of
gross income would change and could preclude CarrAmerica from qualifying as a
REIT (see "--Requirements for Qualification as a REIT--Asset Tests Applicable
to REITs" and "--Income Tests Applicable to REITs" above).

   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 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
Internal Revenue Service

                                      47



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
will be taxed as a partnership for federal income tax purposes, unless it
specifically elects otherwise. The regulations provide that the Internal
Revenue Service 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 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 Internal Revenue Service.

   Allocations of Partnership Income, Gain, Loss and Deduction.  Although a
partnership agreement will generally determine the allocation of income and
loss among partners, such allocations will be disregarded for tax purposes if
they do not comply with the provisions of Section 704(b) of the Internal
Revenue Code and the applicable regulations. Generally, Section 704(b) and the
applicable regulations require that partnership allocations respect the
economic arrangement of the partners.

   If an allocation is not recognized for federal income tax purposes, the item
subject to the allocation will be reallocated in accordance with the partners'
interests in the partnership, which will be determined by taking into account
all of the facts and circumstances relating to the economic arrangement of the
partners with respect to such item. The allocations of taxable income and loss
provided for in the CarrAmerica Realty, L.P. and Carr Realty, L.P. partnership
agreements are intended to comply with the requirements of Section 704(b) of
the Internal Revenue Code and the regulations promulgated thereunder.

   Tax Allocations with Respect to the Properties.  Pursuant to Section 704(c)
of the Internal Revenue Code, income, gain, loss and deduction attributable to
appreciated or depreciated property that is contributed to a partnership in
exchange for an interest in the partnership must be allocated in a manner such
that the contributing partner is charged with, or benefits from, respectively,
the difference between the adjusted tax basis and the fair market value of such
property at the time of contribution. The difference is known as the book-tax
difference. Such allocations are solely for federal income tax purposes and do
not affect the book capital accounts or other economic or legal arrangements
among the partners. Under regulations promulgated under Section 704 of the
Internal Revenue Code, similar rules apply when a partnership elects to
"revalue" its assets in certain situations, such as when a contribution of
property is made to a partnership by a new partner.

   In general, if any asset contributed to or revalued by a partnership is
determined to have a fair market value that is greater than its adjusted tax
basis, certain partners, including CarrAmerica, will be allocated lower amounts
of depreciation deductions as to certain properties for tax purposes and
increased taxable income and gain on sale. Such allocations will tend to
eliminate the book-tax difference over the life of the partnership. However,
the special allocation rules of Section 704(c) of the Internal Revenue Code do
not always entirely rectify the book-tax difference on an annual basis or with
respect to a specific transaction such as a sale. Thus, CarrAmerica may be
allocated lower depreciation and other deductions, and possibly greater amounts
of taxable income in the event of a sale of contributed assets, and such
amounts may be in excess of the economic or book income allocated to it as a
result of such sale. Such an allocation might cause CarrAmerica to recognize
taxable income in excess of cash proceeds, which might adversely affect
CarrAmerica's ability to comply with the REIT distribution requirements. In
this regard, it should be noted that as the general partner of CarrAmerica
Realty, L.P. and Carr Realty, L.P., CarrAmerica will determine when and whether
to sell any given property. See " --Requirements for Qualification as a
REIT--Annual Distribution Requirements Applicable to REITs."

Other Tax Consequences for CarrAmerica and Its Stockholders

   CarrAmerica and its stockholders are 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 CarrAmerica

                                      48



and its stockholders may not conform to the federal income tax consequences
discussed above. Consequently, prospective stockholders of CarrAmerica should
consult their own tax advisors regarding the effect of state and local tax laws
on an investment in CarrAmerica. In this regard, the District of Columbia
imposes an unincorporated business income tax 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, CarrAmerica'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 the properties located in the District of
Columbia will be subject to the District of Columbia tax. This tax would not
apply if CarrAmerica were to own and operate its assets directly, rather than
through Carr Realty, L.P.; however, CarrAmerica's ability to eliminate Carr
Realty, L.P. and thus own directly the assets currently owned by Carr Realty,
L.P. is severely limited.

   A portion of the cash to be used by CarrAmerica to fund distributions comes
from payments received from CarrAmerica's taxable REIT subsidiaries. The
taxable REIT subsidiaries are subject to federal and state income tax at the
full applicable corporate rates. In addition, a taxable REIT subsidiary will be
limited in its ability to deduct interest payments made to CarrAmerica.

   To the extent that CarrAmerica and its subsidiaries are required to pay
federal, state or local taxes, CarrAmerica will have less cash available for
distribution to stockholders.

                             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 with the Company, to
indemnification against and contribution toward certain civil liabilities,
including liabilities under the Securities Act.

   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

                                      49



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.

Resales

   If set forth in the applicable Prospectus Supplement, this Prospectus may be
used in connection with resales or redistributions of Securities by a selling
securityholder. The selling securityholder may be a person who acquired the
Securities from the Company or such a person's pledgees, transferees or other
successors in interest. The Securities may be resold or redistributed from time
to time at varying prices determined at the time of sale, such as market prices
prevailing at the time of sale and prices related to prevailing market prices,
and at negotiated prices. Such a resale or redistribution may be effected
directly or indirectly through brokers or dealers or in a distribution by one
or more underwriters on a firm commitment or best efforts basis, on the NYSE,
in the over-the-counter market, on any other national securities exchange on
which shares of the Securities being resold or redistributed are listed or
traded, in privately negotiated transactions or otherwise. Such resales or
redistributions also may be effected through block trades (which may involve
cross trades) in which the broker or dealer engaged will attempt to sell the
Securities as agent but may position and resell a portion of the block as
principal to facilitate the transaction; purchases by a broker or dealer as
principal and resale by such broker or dealer for its account; exchange
distributions and/or secondary distributions in accordance with the rules of
the NYSE; ordinary brokerage transactions and transactions in which the broker
solicits purchasers; an offering at other than a fixed price on or through the
facilities of the NYSE or to or through a market maker otherwise than on the
NYSE; sales to a dividend reinvestment plan established by the Company, or to
any agent acting on behalf of such plan, for sale to participants in the plan;
pledges to lenders as collateral to secure loans, credit or other financing
arrangements and any subsequent foreclosure thereunder; and any other legally
available means. In effecting sales, brokers or dealers engaged by the selling
securityholder may arrange for other brokers or dealers to participate. Any
public offering price and any discount or concessions allowed or reallowed or
paid to dealers may be changed from time to time. The selling securityholder
may from time to time deliver all or a portion of the Securities covered by a
particular Prospectus Supplement to cover a short sale or sales or upon the
exercise, settlement or closing of a call equivalent position or a put
equivalent position. The broker- dealers participating in such a resale or
redistribution may be deemed "underwriters" within the meaning of the
Securities Act, and any profit on the sale of the Securities and any
commissions received by any such broker-dealers may be regarded as underwriting
commissions under the Securities Act. Selling securityholders, underwriters,
dealers and agents may be entitled, under agreements with the Company, to
indemnification against and contribution toward certain civil liabilities,
including liabilities under the Securities Act.

   The Company will pay all expenses in connection with the registration of
such resales and redistributions. The selling securityholder will pay any
brokerage or underwriting commissions and taxes of any kind (including, without
limitation, transfer taxes).

   In connection with resales and redistributions, the following information
will, to the extent then required, be provided in the applicable Prospectus
Supplement: the number of shares to be sold, the purchase price, the public
offering price, if applicable, the name of any underwriter, agent or broker-
dealer, and any applicable

                                      50



commissions, discounts or other items constituting compensation to
underwriters, agents or broker-dealers with respect to the particular sale or
distribution.

   The rules of the SEC permit an underwriter to engage in certain transactions
that stabilize the price of shares of the Company's Common Stock in connection
with resales or redistributions of the Company's shares of common stock. Such
transactions may consist of bids or purchases for the purpose of pegging,
fixing or maintaining the market price of the shares being sold.

   If an underwriter creates a short position in shares of the Company's Common
Stock in connection with a resale or redistribution, i.e., if it sells more
shares than are set forth on the cover page of the applicable Prospectus
Supplement, the underwriter may reduce that short position by purchasing shares
of the Company's Common Stock in the open market.

   In the case of an underwritten resale of shares, the managing underwriter
may also impose a penalty bid on certain underwriters and selling group
members. This means that, if the managing underwriter purchases shares in the
open market to reduce any underwriter's short position, or to stabilize the
price of the shares of the Company's common stock, the managing underwriter may
reclaim the amount of the selling concession from any such underwriters and
selling group members who sold those shares.

   In general, purchases of a security for the purpose of stabilization or to
reduce a short position could cause the price of the security to be higher than
it might be in the absence of such purchases. The imposition of a penalty bid
might also have an effect on the price of a security to the extent that it
discourages resales of the security.

                                 LEGAL MATTERS

   The legality of the Securities offered hereby has been passed upon for the
Company by Hogan & Hartson L.L.P. Certain federal income tax matters have been
passed upon for the Company by Hogan & Hartson L.L.P.

                                    EXPERTS

   The consolidated financial statements and schedule of the Company and the
Guarantor as of December 31, 2000 and 1999, and for each of the years in the
three-year period ended December 31, 2000, have been incorporated by reference
herein and in the registration statement in reliance upon the report of KPMG
LLP, independent accountants, incorporated by reference herein, and upon the
authority of said firm as experts in accounting and auditing.

   With respect to the unaudited interim financial information of the Company
for the periods ended September 30, 2001 and 2000, June 30, 2001 and 2000 and
March 31, 2001 and 2000 incorporated by reference herein, KPMG LLP has reported
that they applied limited procedures in accordance with professional standards
for a review of such information. However, their separate reports included in
the Company's quarterly reports on Form 10-Q for the quarters ended September
30, 2001, June 30, 2001 and March 31, 2001, and incorporated by reference
herein, state that they did not audit and they do not express an opinion on
that interim financial information. Accordingly, the degree of reliance on
their reports on such information should be restricted in light of the limited
nature of the review procedures applied. KPMG LLP is not subject to the
liability provisions of Section 11 of the Securities Act of 1933 for its
reports on the unaudited interim financial information because those reports
are not "reports" or a "part" of the registration statement prepared or
certified by KPMG LLP within the meaning of Sections 7 and 11 of the Act.
