Agreement.

     "Change of Control" shall mean the occurrence of any of the following
events:

Securities") by any "person" (as the term "person" is used for purposes of
Section 13(d) or Section 14(d) of the Securities Exchange Act of 1934, as
amended (the "Exchange Act")) immediately after which such person has
"beneficial ownership" (within the meaning of Rule 13d-3 promulgated under the
Exchange Act) ("Beneficial Ownership") of 30% or more of the combined voting
power of the Company's then outstanding Voting Securities; provided, however, in
determining whether a Change in Control has occurred, Voting Securities that are
acquired in a Non-Control Acquisition (as hereinafter defined) shall not
constitute an acquisition that would cause a Change in Control. "Non-Control
Acquisition" shall mean an acquisition by (A) an employee benefit plan (or a
trust forming a part thereof) maintained by (1) the Company or (2) any
corporation, partnership or other person of which a majority of its voting power
or its equity securities or equity interest is owned directly or indirectly by
the Company or in which the Company serves as a general partner or manager (a
"Subsidiary"), (B) the Company or any Subsidiary, or (C) any person in
connection with a Non-Control Transaction (as hereinafter defined);

     (ii)  the individuals who constitute the Board of Directors of the Company
as of May 6, 2003 (the "Incumbent Board") cease for any reason to constitute at
least two-thirds (2/3) of the members of the Board of Directors of the Company;
provided, however, that if the election, or nomination for election by the
Company's stockholders, of any new director was approved by a vote of at least
two-thirds (2/3) of the Incumbent Board, such new director shall be considered
as a member of the Incumbent Board; provided, further, that no individual shall
be considered a member of the Incumbent Board if such individual initially
assumed office as a result of either an actual or threatened "election contest"
(as described in Rule 14a-11 promulgated under the



Exchange Act) (an "Election Contest") or other actual or threatened solicitation
of proxies or consents by or on behalf of a person other than the Board of
Directors of the Company (a "Proxy Contest") including by reason of any
agreement intended to avoid or settle any Election Contest or Proxy Contest; or

     (iii) approval by stockholders of the Company of: (A) a merger,
consolidation, share exchange or reorganization involving the Company, unless
(1) the stockholders of the Company immediately before such merger,
consolidation, share exchange or reorganization, own, directly or indirectly
immediately following such merger, consolidation, share exchange or
reorganization, at least 60% of the combined voting power of the outstanding
voting securities of the corporation that is the successor in such merger,
consolidation, share exchange or reorganization (the "Surviving Company") in
substantially the same proportion as their ownership of the Voting Securities
immediately before such merger, consolidation, share exchange or reorganization,
(2) the individuals who were members of the Incumbent Board immediately prior to
the execution of the agreement providing for such merger, consolidation, share
exchange or reorganization constitute at least two-thirds (2/3) of the members
of the board of directors of the Surviving Company, and (3) no persons (other
than the Company or any Subsidiary of the Company, any employee benefit plan (or

Ownership of 30% or more of the then outstanding Voting Securities has
Beneficial Ownership of 30% or more of the combined voting power of the
Surviving Company's then outstanding voting securities (a transaction described
in clauses (1) through (3) is referred to herein as a "Non-Control
Transaction"); (B) a complete liquidation or dissolution of the Company; or (C)
an agreement for the sale or other disposition of all or substantially all of
the assets of the Company to any person (other than a transfer to a Subsidiary
of the Company).

     Notwithstanding the foregoing, a Change of Control shall not be deemed to
occur solely because any person (a "Subject Person") acquired Beneficial
Ownership of more than the permitted amount of the outstanding Voting Securities
as a result of the acquisition of Voting Securities by the Company that, by
reducing the number of Voting Securities outstanding, increases the proportional
number of shares Beneficially Owned by such Subject Person, provided that if a
Change of Control would occur (but for the operation of this sentence) as a
result of the acquisition of Voting Securities by the Company, and after such
share acquisition by the Company, such Subject Person becomes the Beneficial
Owner of any additional Voting Securities that increases the percentage of the
then outstanding Voting Securities Beneficially Owned by such Subject Person,
then a Change of Control shall occur.

distribution, the first date on which the securities on which the dividend or
distribution is payable trade regular way on the relevant exchange or in the
relevant market without the right to receive such dividend or distribution, and

Share on the date immediately prior to such Ex-Date, and (ii) the denominator of

a fraction (x) the numerator of which shall be the number of REIT Shares issued
and outstanding on the Determination Date for such dividend, distribution,
split, subdivision, reverse stock split, combination or reclassification
(assuming for such purposes that such dividend, distribution, split,
subdivision, reverse split or combination has occurred as of such time) and (y)
the denominator of which shall be the actual number of REIT Shares (determined
without the above assumption) issued and outstanding on the Determination Date
for such dividend, distribution, split, subdivision, reverse stock split.

          (c)  The Company shall have authority to appropriately adjust the UDR
Market Capitalization, the UDR Total Return or the Value of a REIT Share if any
other transaction or circumstance occurs or arises that without such adjustment
would have an inequitable result.

     10.  GENERAL.

     The ownership of Class II Out-Performance Partnership Shares may (but need
not, in the sole and absolute discretion of the Company) be evidenced by one or
more certificates. The Company shall amend Exhibit A to the Agreement from time
