            This Amendment No. 19 is filed by Security Capital Group
Incorporated ("Security Capital Group"), a Maryland corporation, SC Realty
Incorporated, a Nevada corporation and an indirect wholly owned subsidiary of
Security Capital Group ("SC-Realty"), Security Capital Operations Incorporated,
a Maryland corporation and wholly owned subsidiary of SC-Realty ("Operations"),
and Security Capital Office Business Trust (formerly East Mixed-Use Realty
Investors Trust) a Maryland real estate investment trust and subsidiary of
Operations ("East"), and amends the Schedule 13D originally filed (as previously
amended, the "Schedule 13D") by Security Capital Group, SC-Realty and Security
Capital Holdings S.A. ("Holdings"), a corporation organized and existing under
the laws of Luxembourg and a wholly owned subsidiary of SC-Realty. This
Amendment No. 19 relates to shares of common stock, par value $0.01 per share
("Common Stock"), of CarrAmerica Realty Corporation, a Maryland corporation
formerly named Carr Realty Corporation ("Carr"). Capitalized terms used herein
without definition shall have the meanings ascribed thereto in the Schedule 13D.

ITEM 4.  PURPOSE OF THE TRANSACTION

Item 4 is hereby amended to add the following:

            On December 3, 2001, Security Capital Group announced that Carr has
filed a prospectus supplement to the shelf registration statement previously
requested by Security Capital and filed by Carr pursuant to the Registration
Request. Pursuant to the prospectus supplement Security Capital expects to offer
16,872,537 shares of Common Stock in an underwritten public offering (the
"Offering"). In connection with the Offering, Security Capital expects also to
grant the underwriters an option to purchase an additional 2,530,880 shares of
Common Stock to cover over-allotments (the "Option"). If all of the offered
shares are sold and the underwriters exercise the Option, Security Capital will
no longer own any shares of Common Stock. A copy of the press release announcing
the Offering is attached hereto as Exhibit 20 and is incorporated herein by
reference. The prospectus supplement is also publicly available through the
EDGAR system.

            Notwithstanding the filing of the prospectus supplement and the
offering of shares of Common Stock pursuant thereto, there can be no assurance
as to the success of the Offering or the terms on which it may take place or
whether Security Capital may determine to abandon or change its plans in
connection with the Offering. Security Capital Group may not sell any or all of
its shares of Common Stock, and intends to continue to actively consider a wide
range of transactions with respect to each of its investments, including Carr,
and may, from time to time, enter into discussions with Carr and/or third
parties, concerning Security Capital Group's holdings of Common Stock and
possible future extraordinary transactions involving Security Capital Group and
Carr, which could involve any of the items enumerated in the Schedule 13D
instructions to this Item 4. Security Capital Group also reserves the right,
based on all relevant factors, and consistent with its contractual obligations,
to change its investment intent with respect to Carr at any time in the future,
to dispose of all or a portion of its holdings of Common Stock, or to change its
intention with respect to any or all of the matters referred to in this Schedule
13D. However, any action or discussions taken in such connection will be subject
to





and conducted in accordance with all applicable legal rules and contractual
agreements to which Security Capital Group is subject or which otherwise apply
to the purchase or sale of Common Stock or Security Capital Group's investment
in Carr including, without limitation, the relevant "standstill" provisions of
the Stockholders Agreement as previously described in this Schedule 13D. Nothing
contained herein is intended to indicate any intent to act otherwise than in
accordance with such provisions and covenants, to modify any such provisions or
to encourage Carr or any other person to do so.

            In reaching any conclusion as to its future course of action,
including whether or not to sell its shares of Common Stock in the Offering,
Security Capital Group will take into consideration various factors, such as
Carr's business and prospects, other developments concerning Carr, other
business opportunities available to Security Capital Group, developments with
respect to the business of Security Capital Group, its contractual obligations
and general economic and stock market conditions, including, but not limited to,
the market price of the Common Stock and of Security Capital Group's own common
stock. There can be no assurance as to whether Security Capital Group will take
any action with respect to its ownership of Common Stock, or enter into any
discussions with Carr or with any third parties with respect to the Common Stock
or Carr, whether such discussions will lead to any transaction that might be
considered or agreed to by any third party, Carr or Security Capital Group, the
terms of any such transaction, or the timing or certainty of any such
transaction.
