     430A Information, together with all other such required information, and,

     comply in all material respects with the applicable requirements of the Act
     and the Exchange Act and the respective rules thereunder; on the Effective
     Date and at the Execution Time, the Registration Statement did not contain

     duly qualified to do business as a foreign corporation or limited
     partnership and is in good standing under the laws of each jurisdiction
     which requires such qualification (except in any case in which the failure

     sale of the Securities and the application of the proceeds thereof as

     jurisdiction in connection with the purchase and distribution of the
     Securities by the Underwriters in the manner contemplated herein and in the
     Prospectus.

          (j)  Neither the issue and sale of the Securities nor the consummation
     of any other of the transactions herein contemplated nor the fulfillment of

     its subsidiaries, taken as a whole, whether or not arising from
     transactions in the ordinary course of business, except as set forth in or
     contemplated in the Prospectus (exclusive of any supplement thereto)), or
     (iii) any statute, law, rule, regulation, judgment, order or decree
     applicable to the Company or any of its subsidiaries of any court,
     regulatory body, administrative agency, governmental body, arbitrator or
     other authority having jurisdiction over the Company or any of its
     subsidiaries or any of its or their properties (except in any case in which
     such would not have a material adverse effect on the condition (financial
     or otherwise), prospects, earnings, business or properties of the Company
     and its subsidiaries, taken as a whole, whether or not arising from
     transactions in the ordinary course of business, except as set forth in or
     contemplated in the Prospectus (exclusive of any supplement thereto)).

          (k)  No holders of securities of the Company have rights to the
     registration of such securities under the Registration Statement.


                                                                               5

     applicable accounting requirements of the Act and have been prepared in
     conformity with generally accepted accounting principles applied on a
     consistent basis throughout the periods involved (except as otherwise noted

     Consolidated Financial Information" in the Prospectus and Registration
     Statement fairly present, on the basis stated in the Prospectus and the
     Registration Statement, the information included therein.

          (m)  No action, suit or proceeding by or before any court or
     governmental agency, authority or body or any arbitrator involving the
     Company or any of its subsidiaries or its or their property is pending or,
     to the best knowledge of the Company, threatened that (i) could reasonably
     be expected to have a material adverse effect on the performance of this
     Agreement or the consummation of any of the transactions contemplated
     hereby or (ii) could reasonably be expected to have a material adverse
     effect on the condition (financial or otherwise), prospects, earnings,
     business or properties of the Company and its subsidiaries, taken as a

     business, except as set forth in or contemplated in the Prospectus

     properties of the Company and its subsidiaries, taken as a whole, whether
     or not arising from transactions in the ordinary course of business, except
     as set forth in or contemplated in the Prospectus (exclusive of any
     supplement thereto)), or (iii) any statute, law, rule, regulation,
     judgment, order or decree of any court, regulatory body, administrative
     agency, governmental body, arbitrator or other authority having

     (except in any case in which such would not have a material adverse effect
     on the condition (financial or otherwise), prospects, earnings, business or
     properties of the Company and its subsidiaries, taken as a whole, whether
     or not arising from transactions in the ordinary course of business, except
     as set forth in or contemplated in the Prospectus (exclusive of any
     supplement thereto)), as applicable.


                                                                               6

     the Securities hereunder.

          (r)  The Company has filed all foreign, federal, state and local tax
     returns that are required to be filed or has requested extensions thereof

     subsidiaries, taken as a whole, whether or not arising from transactions in
     the ordinary course of business, except as set forth in or contemplated in

     effect on the condition (financial or otherwise), prospects, earnings,
     business or properties of the Company and its subsidiaries, taken as a

     business, except as set forth in or contemplated in the Prospectus
     (exclusive of any supplement thereto).

          (s)  No labor problem or dispute with the employees of the Company or
     any of its subsidiaries exists or is threatened or imminent, and the
     Company is not aware of any existing or imminent labor disturbance by the
     employees of any of its or its subsidiaries' principal suppliers,
     contractors or customers, that could have a material adverse effect on the
     condition (financial or otherwise), prospects, earnings, business or
     properties of the Company and its subsidiaries, taken as a whole, whether
     or not arising from transactions in the ordinary course of business, except
     as set forth in or contemplated in the Prospectus (exclusive of any
     supplement thereto).

          (t)  The Company and each of its subsidiaries are insured by insurers
     of recognized financial responsibility against such losses and risks and in
     such amounts as are prudent and customary in the businesses in which they

     instrument as to which any insurance company is denying liability or
     defending under a reservation of rights clause (except in any case in which
     such would not have a material adverse effect on the condition (financial
     or otherwise), prospects, earnings, business or properties of the Company
     and its subsidiaries, taken as a whole, whether or not arising from
     transactions in the ordinary course of business, except as set forth in or
     contemplated in the Prospectus (exclusive of any supplement thereto)); and
     neither the Company nor any such Subsidiary has any reason to believe that
     it will not be able to renew its existing insurance coverage as and when
     such coverage expires or to obtain similar coverage from similar insurers
     as may be necessary to continue its business at a cost that would not have
     a material adverse effect on the condition (financial or otherwise),
     prospects, earnings, business or properties of the Company and its
     subsidiaries, taken as a whole, whether or not arising from transactions in
     the ordinary course of business, except as set forth in or contemplated in
     the Prospectus (exclusive of any supplement thereto).

          (u)  No Subsidiary of the Company is currently prohibited, directly or
     indirectly, from paying any dividends to the Company, from making any other
     distribution on such Subsidiary's capital stock, from repaying to the
     Company any loans or advances to such Subsidiary from the Company or from
     transferring any of such Subsidiary's property or assets to the Company or
     any other Subsidiary of the Company, except as required by the terms of the
     Company's indebtedness described in or contemplated by the Prospectus.

          (v)  The Company and its subsidiaries possess all licenses,
     certificates, permits and other authorizations issued by the appropriate
     federal, state or foreign regulatory authorities necessary to conduct their
     respective businesses (except in any case in which failure to possess such
     would not have a material adverse effect on the condition (financial or
     otherwise), prospects, earnings, business or properties of the Company and
     its subsidiaries, taken as a whole, whether or not arising from
     transactions in the ordinary course of business, except as set forth in or
     contemplated in the Prospectus (exclusive of any supplement thereto)), and
     neither the Company nor any such Subsidiary has received any notice of
     proceedings relating to the revocation or modification of any such
     certificate, authorization or permit which, singly or in the aggregate, if
     the subject of an unfavorable decision, ruling or finding, would have a
     material adverse effect on the condition (financial or otherwise),
     prospects, earnings, business or properties of the Company and its
     subsidiaries, taken as a whole, whether or not arising from transactions in
     the ordinary course of business, except as set forth in or contemplated in
     the Prospectus (exclusive of any supplement thereto).

          (w)  The Company and each of its subsidiaries maintain a system of
     internal accounting controls sufficient to provide reasonable assurance
     that (i) transactions are executed in accordance with management's general
     or specific authorizations; (ii) transactions are recorded as necessary to
     permit preparation of financial statements in conformity with generally
     accepted accounting principles and to maintain asset accountability; (iii)
     access to assets is permitted only in accordance with management's general


                                                                               8


     or specific authorization; and (iv) the recorded accountability for assets
     is compared with the existing assets at reasonable intervals and
     appropriate action is taken with respect to any differences.

          (x)  The Company has not taken, directly or indirectly, any action
     designed to or that would constitute or that might reasonably be expected
     to cause or result in, under the Exchange Act or otherwise, stabilization
     or manipulation of the price of any security of the Company to facilitate
     the sale or resale of the Securities.

          (y)  The Company and its subsidiaries are (i) in compliance with any
     and all applicable foreign, federal, state and local laws and regulations
     relating to the protection of human health and safety, the environment or
     hazardous or toxic substances or wastes, pollutants or contaminants
     ("Environmental Laws"), (ii) have received and are in compliance with all
     permits, licenses or other approvals required of them under applicable
     Environmental Laws to conduct their respective businesses and (iii) have
     not received notice of any actual or potential liability for the
     investigation or remediation of any disposal or release of hazardous or
     toxic substances or wastes, pollutants or contaminants, except where such
     non-compliance with Environmental Laws, failure to receive required
     permits, licenses or other approvals, or liability would not, individually
     or in the aggregate, have a material adverse change in the condition
     (financial or otherwise), prospects, earnings, business or properties of
     the Company and its subsidiaries, taken as a whole, whether or not arising
     from transactions in the ordinary course of business, except as set forth
     in or contemplated in the Prospectus (exclusive of any supplement thereto).
     Except as set forth in the Prospectus, neither the Company nor any of the
     subsidiaries has been named as a "potentially responsible party" under the
     Comprehensive Environmental Response, Compensation, and Liability Act of
     1980, as amended.

          (z)  Each of the Company and its subsidiaries has fulfilled its
     obligations,  if any, under the minimum funding standards of Section 302 of
     the United States Employee Retirement Income Security Act of 1974 ("ERISA")
     and the regulations and published interpretations thereunder with respect
     to each "plan" (as defined in Section 3(3) of ERISA and such regulations
     and published interpretations) in which employees of the Company and its
     subsidiaries are eligible to participate and each such plan is in
     compliance in all material respects with the presently applicable
     provisions of ERISA and such regulations and published interpretations
     (except in any case in which failure to do such would not have a material
     adverse effect on the condition (financial or otherwise), prospects,
     earnings, business or properties of the Company and its subsidiaries, taken
     as a whole, whether or not arising from transactions in the ordinary course
     of business, except as set forth in or contemplated in the Prospectus
     (exclusive of any supplement thereto)).  The Company and its subsidiaries
     have not incurred any unpaid liability to the Pension Benefit Guaranty
     Corporation (other than for the payment of premiums in the ordinary course)
     or to any such plan under Title IV of ERISA (except in any case in which


                                                                               9


     such would not have a material adverse effect on the condition (financial
     or otherwise), prospects, earnings, business or properties of the Company
     and its subsidiaries, taken as a whole, whether or not arising from
     transactions in the ordinary course of business, except as set forth in or
     contemplated in the Prospectus (exclusive of any supplement thereto)).

          (aa) The subsidiaries listed on Exhibit B attached hereto are the only
     significant subsidiaries of the Company as defined by Rule 1-02 of
     Regulation S-X (the "Subsidiaries").

          (bb) The Company and its Subsidiaries own, possess, license or have
     other rights to use, on reasonable terms, all patents, patent applications,
     trade and service marks, trade and service mark registrations, trade names,
     copyrights, licenses, inventions, trade secrets, technology, know-how and
     other intellectual property (collectively, the "Intellectual Property")
     necessary for the conduct of the Company's business as now conducted or as
     proposed in the Prospectus to be conducted.  To the Company's knowledge,
     (a) there is no material infringement by third parties of any such
     Intellectual Property; (b) there is no pending or threatened action, suit,
     proceeding or claim by others challenging the Company's rights in or to any
     such Intellectual Property, and the Company is unaware of any facts which
     would form a reasonable basis for any such claim; (c) there is no pending
     or threatened action, suit, proceeding or claim by others challenging the
     validity or scope of any such Intellectual Property, and the Company is
     unaware of any facts which would form a reasonable basis for any such
     claim; and (d) there is no pending or threatened action, suit, proceeding
     or claim by others that the Company infringes or otherwise violates any
     patent, trademark, copyright, trade secret or other proprietary rights of
     others, and the Company is unaware of any other fact which would form a
     reasonable basis for any such claim.

          (cc)  Except as disclosed in the Registration Statement and the
     Prospectus, the Company (i) does not have any material lending or other
     relationship with any bank or lending affiliate of Salomon Smith Barney
     Holdings Inc. and (ii) does not intend to use any of the proceeds from the
     sale of the Securities hereunder to repay any outstanding debt owed to any
     affiliate of Salomon Smith Barney Holdings Inc.

          (dd)  The Company has been and is organized and has operated in
     conformity with the requirements for qualification and taxation as a REIT
     for each of its taxable years beginning with the earlier of the year ended
     December 31, 1998, or any prior year where the Company's failure to so
     qualify could cause the Company to have a liability for taxes (whether in
     that year or any subsequent year) and its current organization and current
     and proposed method of operation will enable it to continue to meet the
     requirements for qualification and taxation as a REIT.  No transaction
     event has occurred which could cause the Company not to be able to qualify
     as a REIT for its current taxable year or any future taxable year.


                                                                              10



          (ee)  Each of United Dominion Realty L.P. and Heritage Communities
     L.P. (collectively, the "Operating Partnerships") is properly classified as
     a partnership, and not as a corporation or an association taxable as a
     corporation, for Federal income tax purposes throughout the period from its
     formation through the date hereof.

          (ff)  Each of the Subsidiaries that is a partnership or a limited
     liability company ("Subsidiary Partnerships") is properly classified either
     as a disregarded entity or as a partnership, and not as a corporation or as
     an association taxable as a corporation, for Federal income tax purposes
     throughout the period from its formation through the date hereof, or, in
     the case of any Subsidiary Partnerships that have terminated, through the
     date of termination of such Subsidiary Partnerships.

          (gg)  Each of the Company, the Operating Partnerships and its
     Subsidiaries has filed all federal, state, local and foreign income tax
     returns which have been required to be filed and has paid all taxes
     required to be paid and any other assessment, fine or penalty levied
     against it, to the extent that any of the foregoing is due and payable,
     except, in all cases, for any such tax, assessment, fine or penalty that is
     being contested in good faith.  The Company has made adequate charges,
     accruals and reserves in the applicable financial statements referred to in
     Section 1.(l) hereof in respect of all federal, state, local and foreign
     income and franchise taxes for all periods as to which the tax liability of
     the Company or any of the Subsidiaries has not been finally determined.

          Any certificate signed by any officer of the Company and delivered to
the Representatives or counsel for the Underwriters in connection with the
offering of the Securities shall be deemed a representation and warranty by the
Company, as to matters covered thereby, to each Underwriter.

          2.  Purchase and Sale.  (a)  Subject to the terms and conditions and
in reliance upon the representations and warranties herein set forth, the
Company agrees to sell to each Underwriter, and each Underwriter agrees,
severally and not jointly, to purchase from the Company, at a purchase price of
$13.76 per share, the amount of the Underwritten Securities set forth opposite
such Underwriter's name in Schedule I hereto.

          (b)  Subject to the terms and conditions and in reliance upon the
representations and warranties herein set forth, the Company hereby grants an
option to the several Underwriters to purchase, severally and not jointly, the
Option Securities at the same purchase price per share as the Underwriters shall
pay for the Underwritten Securities.  Said option may be exercised only to cover
over-allotments in the sale of the Underwritten Securities by the Underwriters.
Said option may be exercised in whole or in part at any time (but not more than
once) on or before the 30th day after the date of the Prospectus upon written or
telegraphic notice by the Representatives to the Company setting forth the
number of shares of the Option Securities as to which the several Underwriters


                                                                              11


are exercising the option and the settlement date.  The number of shares of the
Option Securities to be purchased by each Underwriter shall be the same
percentage of the total number of shares of the Option Securities to be
purchased by the several Underwriters as such Underwriter is purchasing of the
Underwritten Securities, subject to such adjustments as you in your absolute
discretion shall make to eliminate any fractional shares.

          3.  Delivery and Payment.  Delivery of and payment for the
Underwritten Securities and the Option Securities (if the option provided for in
Section 2(b) hereof shall have been exercised on or before the third Business
Day prior to the Closing Date) shall be made at 10:00 AM, New York City time, on
December 21, 2001, or at such time on such later date not more than three
Business Days after the foregoing date as the Representatives shall designate,
which date and time may be postponed by agreement between the Representatives
and the Company or as provided in Section 9 hereof (such date and time of
delivery and payment for the Securities being herein called the "Closing Date").
Delivery of the Securities shall be made to the Representatives for the
respective accounts of the several Underwriters against payment by the several
Underwriters through the Representatives of the purchase price thereof to or
upon the order of the Company by wire transfer payable in same-day funds to an
account specified by the Company.  Delivery of the Underwritten Securities and
the Option Securities shall be made through the facilities of The Depository
Trust Company unless the Representatives shall otherwise instruct.

          If the option provided for in Section 2(b) hereof is exercised after
the third Business Day prior to the Closing Date, the Company will deliver the
Option Securities (at the expense of the Company) to the Representatives, at 388
Greenwich Street, New York, New York, on the date specified by the
Representatives (which shall be within three Business Days after exercise of
said option) for the respective accounts of the several Underwriters, against
payment by the several Underwriters through the Representatives of the purchase
price thereof to or upon the order of the Company by wire transfer payable in
same-day funds to an account specified by the Company.  If settlement for the
Option Securities occurs after the Closing Date, the Company will deliver to the
Representatives on the settlement date for the Option Securities, and the
obligation of the Underwriters to purchase the Option Securities shall be
conditioned upon receipt of, supplemental opinions, certificates and letters
confirming as of such date the opinions, certificates and letters delivered on
the Closing Date pursuant to Section 6 hereof.

          4.  Offering by Underwriters.  It is understood that the several
Underwriters propose to offer the Securities for sale to the public as set forth
in the Prospectus.

          5.  Agreements.  The Company agrees with the several Underwriters
that:

          (a)  Prior to the termination of the offering of the Securities, the
     Company will not file any amendment of the Registration Statement or
     supplement to the Prospectus or any Rule 462(b) Registration Statement
     unless the Company has furnished you a copy for your review prior to filing


                                                                              12


     and will not file any such proposed amendment or supplement to which you
     reasonably object.  Subject to the foregoing sentence, if the Registration
     Statement has become or becomes effective pursuant to Rule 430A, or filing
     of the Prospectus is otherwise required under Rule 424(b), the Company will
     cause the Prospectus, properly completed, and any supplement thereto to be
     filed with the Commission pursuant to the applicable paragraph of Rule
     424(b) within the time period prescribed and will provide evidence
     satisfactory to the Representatives of such timely filing.  The Company
     will promptly advise the Representatives (1) when the Prospectus, and any
     supplement thereto, shall have been filed with the Commission pursuant to
     Rule 424(b), (2) when, prior to termination of the offering of the
     Securities, any amendment to the Registration Statement shall have been
     filed or become effective, (3) of any request by the Commission or its
     staff for any amendment of the Registration Statement, or any Rule 462(b)
     Registration Statement, or for any supplement to the Prospectus or for any
     additional information, (4) of the issuance by the Commission of any stop
     order suspending the effectiveness of the Registration Statement or the
     institution or threatening of any proceeding for that purpose and (5) of
     the receipt by the Company of any notification with respect to the
     suspension of the qualification of the Securities for sale in any
     jurisdiction or the institution or threatening of any proceeding for such
     purpose.  The Company will use its best efforts to prevent the issuance of
     any such stop order or the suspension of any such qualification and, if
     issued, to obtain as soon as possible the withdrawal thereof.

          (b)  If, at any time when a prospectus relating to the Securities is
     required to be delivered under the Act, any event occurs as a result of
     which the Prospectus as then supplemented would include any untrue
     statement of a material fact or omit to state any material fact necessary
     to make the statements therein in the light of the circumstances under
     which they were made not misleading, or if it shall be necessary to amend
     the Registration Statement or supplement the Prospectus to comply with the
     Act or the Exchange Act or the respective rules thereunder, the Company
     promptly will (1) notify the Representatives of such event, (2) prepare and
     file with the Commission, subject to the second sentence of paragraph (a)
     of this Section 5, an amendment or supplement which will correct such
     statement or omission or effect such compliance and (3) supply any
     supplemented Prospectus to you in such quantities as you may reasonably
     request.

          (c)  As soon as practicable, the Company will make generally available
     to its security holders and to the Representatives an earnings statement or
     statements of the Company and its subsidiaries which will satisfy the
     provisions of Section 11(a) of the Act and Rule 158 under the Act.

          (d)  The Company will furnish to the Representatives and counsel for
     the Underwriters, without charge, copies of the Registration Statement
     (including exhibits thereto) and to each other Underwriter a copy of the
     Registration Statement (without exhibits thereto) and, so long as delivery
     of a prospectus by an Underwriter or dealer may be required by the Act, as
     many copies of the Prospectus and any supplement thereto as the


                                                                              13


     Representatives may reasonably request.  The Company will pay the expenses
     of printing or other production of all documents relating to the offering.

          (e)  The Company will arrange, if necessary, for the qualification of
     the Securities for sale under the laws of such jurisdictions as the
     Representatives may designate, will maintain such qualifications in effect
     so long as required for the distribution of the Securities and will pay any
     fee of the National Association of Securities Dealers, Inc., in connection
     with its review of the offering; provided that in no event shall the
     Company be obligated to qualify to do business in any jurisdiction where it
     is not now so qualified or to take any action that would subject it to
     service of process in suits, other than those arising out of the offering
     or sale of the Securities, in any jurisdiction where it is not now so
     subject.

          (f)  The Company will not, without the prior written consent of
     Salomon Smith Barney Inc., offer, sell, contract to sell, pledge, or
     otherwise dispose of, (or enter into any transaction which is designed to,
     or might reasonably be expected to, result in the disposition (whether by
     actual disposition or effective economic disposition due to cash settlement
     or otherwise) by the Company or any affiliate of the Company or any person
     in privity with the Company or any affiliate of the Company) directly or
     indirectly, including the filing (or participation in the filing) of a
     registration statement with the Commission in respect of, or establish or
     increase a put equivalent position or liquidate or decrease a call
     equivalent position within the meaning of Section 16 of the Exchange Act,
     any other shares of Common Stock or any securities convertible into, or
     exercisable, or exchangeable for, shares of Common Stock; or publicly
     announce an intention to effect any such transaction, for a period of 60
     days after the date of the Underwriting Agreement, provided, however, that
     the Company may issue and sell Common Stock pursuant to any employee stock
     option plan, stock ownership plan or dividend reinvestment plan of the
     Company in effect at the Execution Time and the Company may issue Common
     Stock issuable upon the conversion of securities or the exercise of
     warrants outstanding at the Execution Time.

          (g)  The Company will not take, directly or indirectly, any action
     designed to or that would constitute or that might reasonably be expected
     to cause or result in, under the Exchange Act or otherwise, stabilization
     or manipulation of the price of any security of the Company to facilitate
     the sale or resale of the Securities.

          6.  Conditions to the Obligations of the Underwriters.  The
obligations of the Underwriters to purchase the Underwritten Securities and the
Option Securities, as the case may be, shall be subject to the accuracy of the
representations and warranties on the part of the Company contained herein as of
the Execution Time, the Closing Date and any settlement date pursuant to Section
3 hereof, to the accuracy of the statements of the Company made in any
certificates pursuant to the provisions hereof, to the performance by the
Company of its obligations hereunder and to the following additional conditions:

          (a)  If filing of the Prospectus, or any supplement thereto, is
     required pursuant to Rule 424(b), the Prospectus, and any such supplement,


                                                                              14


     will be filed in the manner and within the time period required by Rule
     424(b); and no stop order suspending the effectiveness of the Registration
     Statement shall have been issued and no proceedings for that purpose shall
     have been instituted or threatened.

     counsel for the Company, to have furnished to the Representatives their

          Subsidiaries are owned by the Company either directly or through
          wholly owned subsidiaries free and clear of any perfected security
          interest and, to the knowledge of such counsel, after due inquiry, any
          other security interest, claim, lien or encumbrance;

          Company or any of its subsidiaries or its or their property of a
          character required to be disclosed in the Registration Statement which
          is not adequately disclosed in the Prospectus, and there is no
          franchise, contract or other document of a character required to be

          issue dates  comply as to form in all material respects with the
          applicable requirements of the Act and the Exchange Act and the
          respective rules thereunder; and such counsel has no reason to believe
          that on the Effective Date, the date the Registration Statement was
          last deemed amended or the date of this Agreement, the Registration

          as of its date or on the Closing Date included or includes any untrue
          statement of a material fact or omitted or omits to state a material
          fact necessary to make the statements therein, in the light of the
          circumstances under which they were made, not misleading (in each
          case, other than the financial statements and other financial and
          statistical information contained therein, as to which such counsel
          need express no opinion);

               (vi)   Each document filed pursuant to the Exchange Act (other

          "investment company" as defined in the Investment Company Act of 1940,
          as amended;

               (ix) no consent, approval, authorization, filing with or order of
          any court or governmental agency or body is required in connection
          with the transactions contemplated herein, except such as have been
          obtained under the Act and such as may be required under the blue sky
          laws of any jurisdiction in connection with the purchase and
          distribution of the Securities by the Underwriters in the manner
          contemplated in this Agreement and in the Prospectus and such other

          breach or violation of or imposition of any lien, charge or
          encumbrance upon any property or assets of the Company or its
          subsidiaries pursuant to, (i) the charter or by-laws of the Company or
          its subsidiaries, (ii) the terms of any indenture, contract, lease,
          mortgage, deed of trust, note agreement, loan agreement or other
          agreement, obligation, condition, covenant or instrument to which the
          Company or its subsidiaries is a party or bound or to which its or
          their property is subject and which has been filed as an exhibit to
          any of the Company's filings made pursuant to the Exchange Act and
          incorporated by reference into the Prospectus, or (iii) any statute,
          law, rule, regulation, judgment, order or decree applicable to the
          Company or its subsidiaries of any court, regulatory body,
          administrative agency, governmental body, arbitrator or other
          authority of the Commonwealth of Virginia or the United States of
          America having jurisdiction over the Company or its subsidiaries or
          any of its or their properties;

               (xi) to such counsel's knowledge, no holders of securities of the
          Company have rights to the registration of such securities under the
          Registration Statement;

          conformity with the requirements for qualification and taxation as a
          REIT for each of its taxable years beginning with the taxable year
          ended December 31, 1998 through December 31, 2000, and its current
          organization and proposed method of operation will enable it to
          continue to meet the requirements for qualification and taxation as a
          REIT for the taxable year 2001 and thereafter; and

               (xiii)  Each of the Operating Partnerships is and has been

                                                                              17


          not as a corporation or as an association or publicly traded
          partnership taxable as a corporation, throughout the period from the
          later of its formation or January 1, 1998 through the date hereof.

     In rendering such opinion, such counsel may rely (A) as to matters
     involving the application of laws of any jurisdiction other than the
     Commonwealth of Virginia or the Federal laws of the United States, to the
     extent they deem proper and specified in such opinion, upon the opinion of
     other counsel of good standing whom they believe to be reliable and who are
     satisfactory to counsel for the Underwriters and (B) as to matters of fact,
     to the extent they deem proper, on certificates of responsible officers of
     the Company and public officials.  References to the Prospectus in this
     paragraph (b) include any supplements thereto at the Closing Date.

          (c)  The Representatives shall have received from Hogan & Hartson
     L.L.P., counsel for the Underwriters, such opinion or opinions, dated the
     Closing Date and addressed to the Representatives, with respect to the
     issuance and sale of the Securities, the Registration Statement, the
     Prospectus (together with any supplement thereto) and other related matters
     as the Representatives may reasonably require, and the Company shall have
     furnished to such counsel such documents as they request for the purpose of
     enabling them to pass upon such matters.

          (d)  The Company shall have furnished to the Representatives a
     certificate of the Company, signed by the Chairman of the Board or the
     President and the principal financial or accounting officer of the Company,
     dated the Closing Date, to the effect that the signers of such certificate
     have carefully examined the Registration Statement, the Prospectus, any
     supplements to the Prospectus and this Agreement and that:

               (i) the representations and warranties of the Company in this
          Agreement are true and correct on and as of the Closing Date with the
          same effect as if made on the Closing Date and the Company has
          complied with all the agreements and satisfied all the conditions on
          its part to be performed or satisfied at or prior to the Closing Date;

               (ii) no stop order suspending the effectiveness of the
          Registration Statement has been issued and no proceedings for that
          purpose have been instituted or, to the Company's knowledge,
          threatened; and

               (iii) since the date of the most recent financial statements
          included or incorporated by reference in the Prospectus (exclusive of
          any supplement thereto), there has been no material adverse effect on
          the condition (financial or otherwise), prospects, earnings, business
          or properties of the Company and its subsidiaries, taken as a whole,
          whether or not arising from transactions in the ordinary course of
          business, except as set forth in or contemplated in the Prospectus
          (exclusive of any supplement thereto).


                                                                              18

          (e)  The Company shall have requested and caused Ernst & Young LLP to
     have furnished to the Representatives, at the Execution Time and at the
     Closing Date, letters, dated respectively as of the Execution Time and as
     of the Closing Date, in form and substance satisfactory to the
     Representatives, confirming that they are independent accountants within
     the meaning of the Act and the Exchange Act and the respective applicable
     rules and regulations adopted by the Commission thereunder and that they
     have performed a review of the unaudited interim financial information of
     the Company for the nine-month period ended September 30, 2001, and as at
     September 30, 2001 in accordance with Statement on Auditing Standards No.
     71, and stating in effect that:

               (i) in their opinion the audited financial statements and
          financial statement schedules included or incorporated by reference in
          the Registration Statement and the Prospectus and reported on by them
          comply as to form in all material respects with the applicable
          accounting requirements of the Act and the Exchange Act and the
          related rules and regulations adopted by the Commission;

               (ii) on the basis of their limited review, in accordance with
          standards established under Statement on Auditing Standards No. 71, of
          the unaudited interim financial information for the nine-month period
          ended September 30, 2001, and as at September 30, 2001 incorporated by
          reference in the Registration Statement and the Prospectus; carrying
          out certain specified procedures (but not an examination in accordance
          with generally accepted auditing standards) which would not
          necessarily reveal matters of significance with respect to the
          comments set forth in such letter; a reading of the minutes of the
          meetings of the stockholders, directors and executive, audit and
          compensation committees of the Company and the Subsidiaries; and
          inquiries of certain officials of the Company who have responsibility
          for financial and accounting matters of the Company and its
          subsidiaries as to transactions and events subsequent to September 30,
          2001, nothing came to their attention which caused them to believe
          that:

                    (1) any unaudited financial statements included or
               incorporated by reference in the Registration Statement and the
               Prospectus do not comply as to form in all material respects with
               applicable accounting requirements of the Act and with the
               related rules and regulations adopted by the Commission with
               respect to financial statements included or incorporated by
               reference in quarterly reports on Form 10-Q under the Exchange
               Act; and said unaudited financial statements are not in
               conformity with generally accepted accounting principles applied
               on a basis substantially consistent with that of the audited
               financial statements included or incorporated by reference in the
               Registration Statement and the Prospectus;


                                                                              19



                    (2) with respect to the period subsequent to September 30,
               2001, there were any changes, at a specified date not more than
               five days prior to the date of the letter, in the capital stock
               of the Company or any increases in consolidated secured debt or
               consolidated unsecured debt or any decreases in the total assets
               or stockholders' equity of the Company as compared with the
               amounts shown on the September 30, 2001 consolidated balance
               sheet included or incorporated by reference in the Registration
               Statement and the Prospectus, or for the period from October 1,
               2001 to such specified date there were any decreases, as compared
               with the corresponding period in the preceding in consolidated
               rental income or income before gains on sales of investments,
               minority interests and extraordinary items or in total or per
               share amounts of net income of the Company and its subsidiaries,
               except in all instances for changes or decreases set forth in
               such letter, in which case the letter shall be accompanied by an
               explanation by the Company as to the significance thereof unless
               said explanation is not deemed necessary by the Representatives;
               and

                    (3) the information included or incorporated by reference in
               the Registration Statement and Prospectus in response to
               Regulation S-K, Item 301 (Selected Financial Data), Item 302
               (Supplementary Financial Information), Item 402 (Executive
               Compensation) and Item 503(d) (Ratio of Earnings to Fixed
               Charges) is not in conformity with the applicable disclosure
               requirements of Regulation S-K;

               (iii) they have performed certain other specified procedures as a
          result of which they determined that certain information of an
          accounting, financial or statistical nature (which is limited to
          accounting, financial or statistical information derived from the
          general accounting records of the Company and its subsidiaries) set
          forth in the Registration Statement and the Prospectus and in Exhibit
          12 to the Registration Statement, including the information set forth
          under the caption "Prospectus Supplement Summary", "United Dominion
          Realty Trust, Inc." and "Ratio of Earnings to Fixed Charges and Ratios
          of Earnings to Combined Fixed Charges and Preferred Dividends" in the
          Prospectus, the information included or incorporated by reference in
          Items 1, 2, 6, 7 and 11 of the Company's Annual Report on Form 10-K,
          incorporated by reference in the Registration Statement and the
          Prospectus, and the information included in the "Management's
          Discussion and Analysis of Financial Condition and Results of
          Operations" included or incorporated by reference in the Company's
          Quarterly Reports on Form 10-Q, incorporated by reference in the
          Registration Statement and the Prospectus, or any such information


                                                                              20


          appearing in a Current Report on Form 8-K incorporated by reference in
          the Registration Statement and the Prospectus, agrees with the
          accounting records of the Company and its subsidiaries, excluding any
          questions of legal interpretation.

          References to the Prospectus in this paragraph (e) include any
          supplement thereto at the date of the letter.

          (f)  Subsequent to the Execution Time or, if earlier, the dates as of
     which information is given in the Registration Statement (exclusive of any
     amendment thereof) and the Prospectus (exclusive of any supplement
     thereto), there shall not have been (i) any change or decrease specified in
     the letter or letters referred to in paragraph (e) of this Section 6 or
     (ii) any change, or any development involving a prospective change, in or
     affecting the condition (financial or otherwise), earnings, business or
     properties of the Company and its subsidiaries, taken as a whole, whether
     or not arising from transactions in the ordinary course of business, except
     as set forth in or contemplated in the Prospectus (exclusive of any
     supplement thereto) the effect of which, in any case referred to in clause
     (i) or (ii) above, is, in the sole judgment of the Representatives, so
     material and adverse as to make it impractical or inadvisable to proceed
     with the offering or delivery of the Securities as contemplated by the
     Registration Statement (exclusive of any amendment thereof) and the
     Prospectus (exclusive of any supplement thereto).

          (g)  Prior to the Closing Date, the Company shall have furnished to
     the Representatives such further information, certificates and documents as
     the Representatives may reasonably request.

          (h)  Subsequent to the Execution Time, there shall not have been any
     decrease in the rating of any of the Company's debt securities by any
     "nationally recognized statistical rating organization" (as defined for
     purposes of Rule 436(g) under the Act) or any notice given of any intended
     or potential decrease in any such rating or of a possible change in any
     such rating that does not indicate the direction of the possible change.

          (i) The Securities shall have been listed and admitted and authorized
     for trading on the New York Stock Exchange, and satisfactory evidence of
     such actions shall have been provided to the Representatives.

          (j)  At the Execution Time, the Company shall have furnished to the
     Representatives a letter substantially in the form of Exhibit A hereto from
     each officer and director of the Company listed on Exhibit C, addressed to
     the Representatives.

          If any of the conditions specified in this Section 6 shall not have
been fulfilled in all material respects when and as provided in this Agreement,
or if any of the opinions and certificates mentioned above or elsewhere in this
Agreement shall not be in all material respects reasonably satisfactory in form
and substance to the Representatives and counsel for the Underwriters, this


                                                                              21


Agreement and all obligations of the Underwriters hereunder may be canceled at,
or at any time prior to, the Closing Date by the Representatives.  Notice of
such cancelation shall be given to the Company in writing or by telephone or
facsimile confirmed in writing.

          The documents required to be delivered by this Section 6 shall be
delivered at the office of Hogan & Hartson LLP, counsel for the Underwriters, at
555 Thirteenth Street, NW, Washington, DC  20004, on the Closing Date.

          7.  Reimbursement of Underwriters' Expenses.  If the sale of the
Securities provided for herein is not consummated because any condition to the
obligations of the Underwriters set forth in Section 6 hereof is not satisfied
because of any refusal, inability or failure on the part of the Company to
perform any agreement herein or comply with any provision hereof other than by
reason of a default by any of the Underwriters, the Company will reimburse the
Underwriters severally through Salomon Smith Barney Inc. on demand for all
reasonable documented out-of-pocket expenses (including reasonable fees and
disbursements of counsel) that shall have been incurred by them in connection
with the proposed purchase and sale of the Securities.

          8.  Indemnification and Contribution.  (a)  The Company agrees to
indemnify and hold harmless each Underwriter, the directors, officers, employees
and agents of each Underwriter and each person who controls any Underwriter
within the meaning of either the Act or the Exchange Act against any and all
losses, claims, damages or liabilities, joint or several, to which they or any
of them may become subject under the Act, the Exchange Act or other Federal or
state statutory law or regulation, at common law or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any untrue statement or alleged untrue statement of a
material fact contained in the registration statement for the registration of
the Securities as originally filed or in any amendment thereof, or in the
Prospectus, or in any amendment thereof or supplement thereto, or arise out of
or are based upon the omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein
not misleading, and agrees to reimburse each such indemnified party, as
incurred, for any legal or other expenses reasonably incurred by them in
connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that the Company will not be liable in
any such case to the extent that any such loss, claim, damage or liability
arises out of or is based upon any such untrue statement or alleged untrue
statement or omission or alleged omission made therein in reliance upon and in
conformity with written information furnished to the Company by or on behalf of
any Underwriter through the Representatives specifically for inclusion therein.
This indemnity agreement will be in addition to any liability which the Company
may otherwise have.

          (b)  Each Underwriter severally and not jointly agrees to indemnify
and hold harmless the Company, each of its directors, each of its officers who
signs the Registration Statement, and each person who controls the Company
within the meaning of either the Act or the Exchange Act, to the same extent as
the foregoing indemnity from the Company to each Underwriter, but only with
reference to written information relating to such Underwriter furnished to the


                                                                              22


Company by or on behalf of such Underwriter through the Representatives
specifically for inclusion in the documents referred to in the foregoing
indemnity.  This indemnity agreement will be in addition to any liability which
any Underwriter may otherwise have.  The Company acknowledges that the
statements set forth in the last paragraph of the cover page regarding delivery
of the Securities and, under the heading "Underwriting", (i) the list of
Underwriters and their respective participation in the sale of the Securities,
(ii) the sentences related to concessions and reallowances and (iii) the
paragraph related to stabilization, syndicate covering transactions and penalty
bids in the Prospectus constitute the only information furnished in writing by
or on behalf of the several Underwriters for inclusion in the Prospectus.


         (c)  Promptly after receipt by an indemnified party under this Section
8 of notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section 8, notify the indemnifying party in writing of the commencement thereof;
but the failure so to notify the indemnifying party (i) will not relieve it from
liability under paragraph (a) or (b) above unless and to the extent it did not
otherwise learn of such action and such failure results in the forfeiture by the
indemnifying party of substantial rights and defenses and (ii) will not, in any
event, relieve the indemnifying party from any obligations to any indemnified
party other than the indemnification obligation provided in paragraph (a) or (b)
above. The indemnifying party shall be entitled to appoint counsel of the
indemnifying party's choice at the indemnifying party's expense to represent the
indemnified party in any action for which indemnification is sought (in which
case the indemnifying party shall not thereafter be responsible for the fees and
expenses of any separate counsel retained by the indemnified party or parties
except as set forth below); provided, however, that such counsel shall be
satisfactory to the indemnified party. Notwithstanding the indemnifying party's
election to appoint counsel to represent the indemnified party in an action, the
indemnified party shall have the right to employ separate counsel (including
local counsel), and the indemnifying party shall bear the reasonable fees, costs
and expenses of such separate counsel if (i) the use of counsel chosen by the
indemnifying party to represent the indemnified party would present such counsel
with a conflict of interest, (ii) the actual or potential defendants in, or
targets of, any such action include both the indemnified party and the
indemnifying party and the indemnified party shall have reasonably concluded
that there may be legal defenses available to it and/or other indemnified
parties which are different from or additional to those available to the
indemnifying party, (iii) the indemnifying party shall not have employed counsel
satisfactory to the indemnified party to represent the indemnified party within
a reasonable time after notice of the institution of such action or (iv) the
indemnifying party shall authorize the indemnified party to employ separate
counsel at the expense of the indemnifying party. It is understood, however,
that the indemnifying party shall, in connection with any one such action or
separate but substantially similar or related actions in the same jurisdiction
arising out of the same general allegations or circumstances, be liable for the
fees and expenses of only one separate firm of attorneys (in addition to any
local counsel) at any time for all such indemnified parties, which firm shall be
designated in writing by such indemnified parties. An indemnifying party will
not, without the prior written consent of the indemnified parties, settle or
compromise or consent to the entry of any judgment with respect to any pending


                                                                              23


or threatened claim, action, suit or proceeding in respect of which
indemnification or contribution may be sought hereunder (whether or not the
indemnified parties are actual or potential parties to such claim or action)
unless such settlement, compromise or consent includes an unconditional release
of each indemnified party from all liability arising out of such claim, action,
suit or proceeding.

          (d)  In the event that the indemnity provided in paragraph (a) or (b)
of this Section 8 is unavailable to or insufficient to hold harmless an
indemnified party for any reason, the Company and the Underwriters severally
agree to contribute to the aggregate losses, claims, damages and liabilities
(including legal or other expenses reasonably incurred in connection with
investigating or defending same) (collectively "Losses") to which the Company
and one or more of the Underwriters may be subject in such proportion as is
appropriate to reflect the relative benefits received by the Company on the one
hand and by the Underwriters on the other from the offering of the Securities;
provided, however, that in no case shall any Underwriter (except as may be
provided in any agreement among underwriters relating to the offering of the
Securities) be responsible for any amount in excess of the underwriting discount
or commission applicable to the Securities purchased by such Underwriter
hereunder.  If the allocation provided by the immediately preceding sentence is
unavailable for any reason, the Company and the Underwriters severally shall
contribute in such proportion as is appropriate to reflect not only such
relative benefits but also the relative fault of the Company on the one hand and
of the Underwriters on the other in connection with the statements or omissions
which resulted in such Losses as well as any other relevant equitable
considerations.  Benefits received by the Company shall be deemed to be equal to
the total net proceeds from the offering (before deducting expenses) received by
it, and benefits received by the Underwriters shall be deemed to be equal to the
total underwriting discounts and commissions, in each case as set forth on the
cover page of the Prospectus.  Relative fault shall be determined by reference
to, among other things, whether any untrue or any alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact
relates to information provided by the Company on the one hand or the
Underwriters on the other, the intent of the parties and their relative
knowledge, access to information and opportunity to correct or prevent such
untrue statement or omission.  The Company and the Underwriters agree that it
would not be just and equitable if contribution were determined by pro rata
allocation or any other method of allocation which does not take account of the
equitable considerations referred to above.  Notwithstanding the provisions of
this paragraph (d), no person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation.  For purposes of
this Section 8, each person who controls an Underwriter within the meaning of
either the Act or the Exchange Act and each director, officer, employee and
agent of an Underwriter shall have the same rights to contribution as such
Underwriter, and each person who controls the Company within the meaning of
either the Act or the Exchange Act, each officer of the Company who shall have
signed the Registration Statement and each director of the Company shall have
the same rights to contribution as the Company, subject in each case to the
applicable terms and conditions of this paragraph (d).


                                                                              24


          9.  Default by an Underwriter.  If any one or more Underwriters shall
fail to purchase and pay for any of the Securities agreed to be purchased by
such Underwriter or Underwriters hereunder and such failure to purchase shall
constitute a default in the performance of its or their obligations under this
Agreement, the remaining Underwriters shall be obligated severally to take up
and pay for (in the respective proportions which the amount of Securities set
forth opposite their names in Schedule I hereto bears to the aggregate amount of
Securities set forth opposite the names of all the remaining Underwriters) the
Securities which the defaulting Underwriter or Underwriters agreed but failed to
purchase; provided, however, that in the event that the aggregate amount of
Securities which the defaulting Underwriter or Underwriters agreed but failed to
purchase shall exceed 10% of the aggregate amount of Securities set forth in
Schedule I hereto, the remaining Underwriters shall have the right to purchase
all, but shall not be under any obligation to purchase any, of the Securities,
and if such nondefaulting Underwriters do not purchase all the Securities, this
Agreement will terminate without liability to any nondefaulting Underwriter or
the Company.  In the event of a default by any Underwriter as set forth in this
Section 9, the Closing Date shall be postponed for such period, not exceeding
five Business Days, as the Representatives shall determine in order that the
required changes in the Registration Statement and the Prospectus or in any
other documents or arrangements may be effected.  Nothing contained in this
Agreement shall relieve any defaulting Underwriter of its liability, if any, to
the Company and any nondefaulting Underwriter for damages occasioned by its
default hereunder.

          10.  Termination.  This Agreement shall be subject to termination in
the absolute discretion of the Representatives, by notice given to the Company
prior to delivery of and payment for the Securities, if at any time prior to
such time (i) trading in the Company's Common Stock shall have been suspended by
the Commission or the New York Stock Exchange or trading in securities generally
on the New York Stock Exchange shall have been suspended or limited or minimum
prices shall have been established on such Exchange, (ii) a banking moratorium
shall have been declared either by Federal or New York State authorities or
(iii) there shall have occurred any outbreak or escalation of hostilities,
declaration by the United States of a national emergency or war, or other
calamity or crisis the effect of which on financial markets is such as to make
it, in the sole judgment of the Representatives, impractical or inadvisable to
proceed with the offering or delivery of the Securities as contemplated by the
Prospectus (exclusive of any supplement thereto).

          11.  Representations and Indemnities to Survive. The respective
agreements, representations, warranties, indemnities and other statements of the
Company or its officers and of the Underwriters set forth in or made pursuant to
this Agreement will remain in full force and effect, regardless of any
investigation made by or on behalf of any Underwriter or the Company or any of
the officers, directors, employees, agents or controlling persons referred to in
Section 8 hereof, and will survive delivery of and payment for the Securities.
The provisions of Sections 7 and 8 hereof shall survive the termination or
cancelation of this Agreement.

          12.  Notices.  All communications hereunder will be in writing and
effective only on receipt, and, if sent to the Representatives, will be mailed,


                                                                              25
