          This statement on Schedule 13D (this "Statement") relates to the
common stock, par value $1.00 per share (the "Common Stock"), of United
Dominion Realty Trust, Inc., a Virginia corporation (the "Company"). The
principal executive offices of the Company are located at 10 South Sixth
Street, Richmond, Virginia 23219-3802.


Item 2.   Identity and Background

          (a), (b), (c) and (f). This Statement is filed by LF Strategic
Realty Investors (the "Fund") and Lazard Freres Real Estate Investors
L.L.C. ("LFREI" and, together with the Fund, the "Reporting Persons"). The
principal business office of each of the Reporting Persons is at 30
Rockefeller Plaza, 63rd Floor, New York, New York, 10020.

          The Fund, a Delaware limited partnership comprised of
institutional investors, engages primarily in the business of investing in
real estate related companies. LFREI, a New York limited liability company,
is the general partner of the Fund. LFREI's activities consist principally
of acting as general partner of several real estate investment partnerships
that are affiliated with Lazard Freres & Co. LLC. ("Lazard"). Lazard
disclaims beneficial ownership of any of the shares of Common Stock
reported in this Statement. The name, business address and principal
occupation or employment of the executive officers of LFREI are set forth
on Schedule 1 hereto and incorporated by reference herein. Each person
listed on such Schedule 1 is a citizen of the United States.

          (d) and (e). During the last five years, neither the Reporting
Persons nor, to the best knowledge of the Reporting Persons, any of the
persons listed on Schedule 1 (i) has been convicted in a criminal
proceeding (excluding traffic violations or similar misdemeanors) nor (ii)
has been a party to any civil proceeding of a judicial or administrative
body of competent jurisdiction, and is or was, as a result of such
proceeding, subject to a judgment, decree or final order enjoining future
violations of, or prohibiting or mandating activities subject to, federal

laws.


Item 3.   Source and Amount of Funds or Other Consideration

          The consideration for the acquisition of the shares of Common
Stock that are the subject of this

                                Page 4 of 9

<PAGE>


Statement consist of 852,868.26 shares of Common Stock, par value $.01 per
share (the "AAC Common Stock") of American Apartment Communities II, Inc.,
a Maryland corporation ("AAC") and 169,900 shares of Class A Redeemable
Preferred Stock, par value $.01 per share (the "AAC Preferred Stock"), of
AAC, which shares are to be exchanged in the Merger described in Item 4.


Item 4.   Purpose of Transaction

          On September 10, 1998, the Company and AAC entered into an
Agreement and Plan of Merger (the "Merger Agreement") wherein the parties
agreed that, subject to certain conditions being met, AAC would be merged
(the "Merger") with and into the Company with the Company being the
surviving corporation. The Merger proceeds will consist of (i) cash and
(ii) 7.812742 shares of Series D Cumulative Convertible Preferred Stock of
the Company (the "Series D Preferred Stock") per share of AAC Common Stock
and AAC Preferred Stock exchanged in the Merger. Pursuant to the terms of
the Series D Preferred Stock, the Series D Preferred Stock is immediately
convertible into shares of Common Stock in accordance with such terms.

          While the Fund has not obtained actual record ownership of the
shares of Common Stock reported by this Statement, the Fund may be deemed
to have acquired beneficial ownership (within the meaning of Rule 13d-3
promulgated under the Securities Exchange Act of 1934) of such shares upon
the signing of the Merger Agreement as a result of AAC's binding commitment
to consummate the Merger, subject only to the conditions set forth in the
Merger Agreement, and the ability of the Fund to immediately convert the
shares of Series D Preferred Stock it receives in connection with the
Merger into shares of Common Stock.

          Pursuant to the Merger Agreement, at the effective time of the
Merger (the "Effective Time"), the board of directors of the Company (the
"Board") shall be expanded by two members, and the existing directors of
the Company shall elect James D. Klingbeil and Robert P. Freeman as
directors of the Company to serve until the annual meeting of shareholders
of the Company in 1999. Mr. Freeman is a Principal of LFREI. In addition,
following the Effective Time, any shareholder of AAC who Beneficially Owns
(as defined in the Merger Agreement) on the record date for determination
of shareholders of the Company entitled to vote at any annual meeting of
shareholders or other meeting at which the Board is elected (the "Record
Date") shares of preferred stock of the Company, or shares of Common Stock
received upon conversion thereof ("Conversion Stock") or a combination
thereof, having an aggregate Nominal Value (as defined in the Merger
Agreement) of $150,000,000 shall have

                                Page 5 of 9

<PAGE>


the right to nominate two persons for election to the Board, and in the
event any shareholder of AAC Beneficially Owns preferred stock of the
Company or Conversion Stock with an aggregate Nominal Value of less than
$150,000,000 but more than $100,000,000, such person shall have the right
to nominate one person for election to the Board. Such nominations will be
made in consultation with the Board, provided that at any time at which
such a person shall have the right to nominate two persons for election to
the Board, if at such time James D. Klingbeil is nominated for reelection
by the incumbent members of the Board he shall be deemed one of the persons
nominated.

          Pursuant to the Merger Agreement, at the Effective Time the
articles of incorporation of the Company will be amended to include the
terms of the Series D Preferred Stock. The terms of the Series D Preferred
Stock are attached to this Statement as Exhibit 2.

          Except as set forth herein, the Reporting Persons have no plans
or proposals of the type referred to in clauses (a) through (j) of Item 4
of Schedule 13D.

          The foregoing discussion of the Merger Agreement is qualified in

deemed to have Beneficial Ownership of approximately 12,307,692 shares of
Common Stock, or 10.4% of the shares of Common Stock issued and outstanding

Common Stock issuable upon the conversion of Series D Preferred Stock
received by the Fund). The Reporting Persons have no other ownership
interest in the Company except as set forth above.

          (b) The Reporting Persons have the sole power to vote and direct

Merger, the Fund and certain other persons are required to enter into an
Investment Agreement (the "Investment Agreement") with the Company in the

Agreement, which form of Investment Agreement is attached to this Statement
as Exhibit 4 and incorporated herein by reference. The Investment Agreement
contains, among other things, restrictions on the transferability of the

and registration rights with respect to the Common Stock issued upon

<PAGE>

          Section 1.6. No Appraisal Rights.

          The holders of AAC Common Stock and AAC Preferred Stock (as
defined below) shall not be entitled to appraisal rights as a result of the
Merger.

                                 ARTICLE II

               MERGER CONSIDERATION; EFFECT OF THE MERGER ON
             THE CAPITAL STOCK OF THE CONSTITUENT CORPORATIONS


          Section 2.1. Effect on Capital Stock.

          By virtue of the Merger and without any action on the part of the
holders of any shares of AAC Common Stock or AAC Preferred Stock (as
defined below):

          (a) Conversion of AAC Common Stock

               (i) At the Effective Time, each issued and outstanding share
          of Common Stock, $.01 par value, of AAC (the "AAC Common Stock")
          shall be converted into $46.1824 in cash (the "Common Cash
          Consideration") and 7.812742 shares of Company Series D Preferred
          Stock, with the amount of Common Cash Consideration and such
          number of shares of Company Series D Preferred Stock to be
          adjusted appropriately to reflect the effect of any reverse stock
          split or combination permitted pursuant to Section 4.1(a).

               (ii) At the Effective Time, all such shares of AAC Common
          Stock shall no longer be outstanding and shall automatically be
          canceled and retired and all rights with respect thereto shall
          cease to exist, and each holder of a certificate representing any
          such shares of AAC Common Stock shall cease to have any rights
          with respect thereto, except the right to receive cash and shares
          of Company Series D Preferred Stock in accordance with this
          Section 2.1( (a)) and Section 2.1( (c)) (the "Common Merger
          Consideration"), without interest.

               (iii) Notwithstanding the foregoing, the parties understand
          that the rights of each stockholder of AAC under this Section
          2.1( (a)) will be subject to the stop transfer and redemption
          provisions contained in Article 4 of the Articles of
          Incorporation of the Company (the "Company Charter").

               (iv) The Common Cash Consideration shall be subject to
          adjustment as provided in Section 2.2.

          (b) Conversion of AAC Preferred Stock.

               (i) At the Effective Time, each issued and outstanding share
          of Class A Cumulative Redeemable Preferred Stock, $.01 par value,
          of AAC (the "AAC Preferred Stock") shall be converted into
          $46.1824 in cash (the "Preferred Cash Consideration" 
<PAGE>

          and, together with the Common Cash Consideration, the "Merger
          Cash Consideration") and 7.812742 shares of Company Series D
          Preferred Stock, with the amount of Preferred Cash Consideration
          and such number of shares of Company Series D Preferred Stock to
          be adjusted appropriately to reflect the effect of any reverse
          stock split or combination permitted pursuant to Section 4.1(a).

               (ii) At the Effective Time, all such shares of AAC Preferred
          Stock shall no longer be outstanding and shall automatically be
          canceled and retired and all rights with respect thereto shall
          cease to exist, and each holder of a certificate representing any
          such shares of AAC Preferred Stock shall cease to have any rights
          with respect thereto, except the right to receive cash and
          certificates representing the shares of Company Series D
          Preferred Stock in accordance with this Section 2.1( (b)) and
          Section 2.1(c) upon surrender of such certificate (the "Preferred
          Merger Consideration" and, together with the Common Merger
          Consideration, the "Merger Consideration"), without interest.

               (iii) Notwithstanding the foregoing, the parties understand
          that the rights of each stockholder of AAC under this Section
          2.1( (b)) will be subject to the stop transfer and redemption
          provisions contained in Article 4 of the Company Charter.

               (iv) The Preferred Cash Consideration shall be subject to
          adjustment as provided in Section 2.2.

          (c) Cash in Lieu of Fractional Shares. Notwithstanding any other
provision hereof, no fractional shares of Company Series D Preferred Stock
shall be issued in connection with the Merger. Instead, each shareholder of
AAC having a fractional interest arising upon the conversion or exchange of
such shares in connection with the Merger shall be paid an amount in cash
equal to $25 multiplied by the fraction of a share of Company Series D
Preferred Stock to which such holder would otherwise be entitled. No such
holder shall be entitled to dividends or other distributions, voting rights
or any other shareholder rights in respect of any fractional share.

          (d) No Effect on Outstanding Shares of the Company. Each
shareholder of the Company whose shares were outstanding immediately before
the Effective Date will hold the same number of shares of the Surviving
Corporation, with identical designations, preferences, limitations and
relative rights, immediately thereafter.

          (e) No Further Transfer of AAC Stock. At and after the Effective
Time, no transfer of any shares of AAC Common Stock and/or AAC Preferred
Stock shall be recorded on the books of AAC. The Company shall not be bound
to recognize for any purpose any transfer or purported transfer of AAC
Common Stock and/or AAC Preferred Stock occurring after the Effective Time.

          Section 2.2. Adjustment to Merger and Exchange Consideration.

          (a) Closing Balance Sheet. As of the Closing Date, AAC will
prepare and deliver to the Company a closing consolidated balance sheet of
AAC and the AAC Subsidiaries (as defined



<PAGE>

herein) that will reflect, as of the Closing Date, appropriate closing
adjustments and accruals made in accordance with generally accepted
accounting principles consistently applied ("GAAP"), except as provided
below (the "Closing Balance Sheet"). The Closing Balance Sheet will
eliminate (i) the historical cost of AAC's real estate assets net of
accumulated depreciation, which amount will be replaced by the values
assigned to such real estate assets on Schedule A hereto and (ii) the
historical cost of AAC's minority interest in University Village, which
interest will be reflected on the Closing Balance Sheet at a value of $2.9
million. Giving effect to such adjustments, AAC's assets net of its
liabilities as reflected on the Closing Balance Sheet will be referred to
as the "Net Asset Value." The Closing Balance Sheet will (w) exclude
deferred financing costs, (x) exclude any intangible assets which do not
have continuing economic value and (y) not reflect any liability associated
with any promotional interests held by third parties with respect to the
AAC Properties listed under Entity Level Properties on Schedule 3.1(p) to
the AAC Disclosure Letter and (z) include expenses of AAC in connection
with the Merger and the Exchange (including the fees and expenses of
counsel to AAC and AACLP, any fees and expenses of Lazard Freres & Co. LLC
("Lazard") and the fees and expenses of counsel to Lazard) accrued to the
Closing Date as a liability without recording any corresponding asset. The
Closing Balance Sheet will include the aggregate amount of AAC's
indebtedness as of the Closing Date, but will not be adjusted to reflect
any changes to the valuation of the real estate assets, leasehold interests
or minority interests referred to on Schedule A hereto. Attached hereto as
Schedule A-1, by way of illustration, is the June 30, 1998, consolidated
balance sheet of AAC, indicating in notes thereto the kinds of adjustments
to be made pursuant to this Section 2.2 to create the Closing Balance
Sheet. AAC will identify to the Company the personnel having responsibility
for the accounting records utilized in preparation of the Closing Balance
Sheet and will use its best efforts to make them available to the Company
and its representatives in connection with any review of this process the
Company may undertake, for purposes of resolution of any dispute pursuant
to Section 2.2(b) or otherwise.

          (b) Disputes. In the event that the Company disputes any item(s)
on the Closing Balance Sheet, the Company shall deliver a detailed
statement describing such objections to AAC within 60 days after receiving
the Closing Balance Sheet. AAC and the Company will use reasonable efforts
to resolve any such objections themselves. If the parties are unable to
obtain a final resolution within 30 days, AAC and the Company will submit
any unresolved objections to Ernst & Young LLP for resolution. The
determination of Ernst & Young LLP shall be conclusive, final and binding
on the parties.

          (c) Adjustments to Transaction Consideration. The aggregate
Merger Consideration and the aggregate consideration provided for in
Section 1 of the Exchange Agreement (together, the "Aggregate
Consideration") will be adjusted as follows:

               (i) If the Net Asset Value, as reflected on the Closing
          Balance Sheet as finally determined, is less than $336.5 million,
          then the Aggregate Consideration will be decreased in an amount
          equal to the excess of $336.5 million over the Net Asset Value as
          reflected on the Closing Balance Sheet as finally determined;


<PAGE>

               (ii) If the Net Asset Value, as reflected on the Closing
          Balance Sheet as finally determined, is greater than $336.5
          million, then the Aggregate Consideration will be increased in an
          amount equal to the excess of the Net Asset Value as reflected on
          the Closing Balance Sheet as finally determined over $336.5
          million;

               (iii) If the Net Asset Value, as reflected on the Closing
          Balance Sheet as finally determined, is equal to $336.5 million,
          then there will be no adjustment to the Aggregate Consideration
          pursuant to this paragraph (c); and

               (iv) The amount of any increase or decrease in the Aggregate
          Consideration shall be allocated among the holders of partnership
          interests in AACLP (the "AACLP Interest Holders") based on
          Section 5.2 of the Second Amended and Restated Agreement of
          Limited Partnership of AACLP, as amended and supplemented (the
          "AACLP Partnership Agreement"). (No portion of any increase or
          decrease shall be allocated to the Redeemable Preferred Capital
          of AACLP.) The portion of such increase or decrease allocated to
          AAC shall increase or decrease, as the case may be, dollar for
          dollar the aggregate Merger Cash Consideration and shall increase
          or decrease the aggregate Common Cash Consideration and aggregate
          Preferred Cash Consideration pro rata, and the increases or
          decreases in the aggregate Common Cash Consideration and
          aggregate Preferred Cash Consideration shall increase or decrease
          the per share Common Cash Consideration and per share Preferred
          Cash Consideration, respectively, on the basis of the number of
          shares of AAC Common Stock and AAC Preferred Stock, respectively,
          issued and outstanding on the Closing Date. The portion of such
          increase or decrease allocated to the AACLP Interest Holders
          other than AAC shall increase or decrease, as the case may be,
          the consideration provided for in Section 1 of the Exchange
          Agreement as follows. Any increase or decrease allocated to each
          such holder shall be applied dollar for dollar to the cash
          portion of such consideration with respect to each such AACLP
          Interest Holder other than AAC OP. Any increase or decrease
          allocated to AAC OP shall increase or decrease the number of UDR
          Units issuable to AAC OP on the basis of a UDR Unit value of
          $14.25.

          (d) Adjustments for Rights of First Refusal. In the event that
any third party exercises its right of first refusal in respect of AAC's
interests in any of the AAC Partnerships listed on Schedule B hereto (the
"Rights of First Refusal") and such interests are purchased before the
Closing Date for an amount which exceeds the amount allocated to such AAC
Partnership set forth on Schedule B, then the Aggregate Consideration shall
be increased by such excess. Any such increase shall be allocated in
accordance with Section 2.2(c).

          (e) Holdback. An aggregate of $3,000,000 of cash shall be
withheld by the Company from the Aggregate Consideration (the "Holdback
Amount"). The Holdback Amount will be used to pay liabilities not disclosed
in the Closing Balance Sheet and the schedules to the AAC Disclosure Letter
that are required to be so disclosed under GAAP. On the 60th day following
the Closing Date, the balance of the Holdback Amount, including any
interest which has accrued thereon, will be distributed to the former
shareholders of AAC and the limited partners of AACLP as directed by a
former executive officer of AAC to be designated by AAC at or before 


<PAGE>

the Closing. Any dispute regarding the propriety of any deductions to the
Holdback Amount will be resolved by the parties themselves or, if the
parties are unable to so agree, by Ernst & Young LLP in the manner
described in Section 2.2(b).

          Section 2.3. Dividend Distributions.

          In order to satisfy the requirements of Section 857(a)(1) of the
Code for the taxable year of AAC ending at the Closing Date (and to avoid
the payment of tax with respect to undistributed income), AAC shall declare
a dividend on one or more classes of its outstanding capital stock (the
"Final AAC REIT Dividend"), the record date for which shall be
approximately five business days prior to the Closing Date, in an amount
that the Company and AAC shall agree is equal to the minimum dividend
sufficient (taking into account expected revenue and expenses through the
day prior to the Closing Date) to permit AAC to satisfy such requirements.
If AAC determines it necessary to declare the Final AAC REIT Dividend, it
shall notify the Company prior to the Closing Date. The Final AAC REIT
Dividend shall be paid on the close of business on the last business day
prior to the Closing Date.

          Section 2.4. Withholding Rights.

          The Company shall be entitled to deduct and withhold from any
Merger Consideration otherwise payable pursuant to this Agreement to any
holder of shares of AAC Common Stock or AAC Preferred Stock such amounts as
the Company is required to deduct and withhold with respect to the making
of such payment under the Code, or any provision of state, local or foreign
tax law. To the extent that amounts are so withheld by the Company, such
withheld amounts shall be treated for all purposes of this Agreement as
having been paid to the holder of the shares of AAC Common Stock or AAC
Preferred Stock, in respect of which such deduction and withholding was
made by the Company.

                                ARTICLE III

                       REPRESENTATIONS AND WARRANTIES


          Section 3.1. Representations and Warranties of AAC.

          AAC represents and warrants to the Company as follows:

          (a) Organization, Standing and Corporate Power of AAC. AAC is a
corporation duly organized and validly existing under the laws of Maryland
and has the requisite corporate power and authority to carry on its
business as now being conducted. AAC is duly qualified or licensed to do
business and is in good standing in each jurisdiction in which the nature
of its business or the ownership, leasing of its properties or management
of properties for others makes such qualification or licensing necessary,
other than in such jurisdictions where the failure to be so qualified or
licensed, individually or in the aggregate, would not have a material
adverse effect on the business, properties, assets, financial condition or
results of operations of AAC and the AAC Entities (as defined herein),
taken as a whole (an "AAC Material Adverse Effect").


<PAGE>

          (b) AAC Subsidiaries and Investees.

               (i) Schedule 3.1( (b))((i))(1) to the AAC Disclosure Letter
          is a true and complete list of all corporations with respect to
          which AAC operates, owns or otherwise controls, directly or
          indirectly through one or more subsidiaries, partnerships, joint
          ventures or other business associations, a majority of the
          outstanding voting securities (the "AAC Subsidiaries"). Schedule
          3.1( (b))((i))(1) to the AAC Disclosure Letter accurately sets
          forth for each AAC Subsidiary (a) its name and jurisdiction of
          incorporation, (b) the number of shares of authorized capital
          stock of each class of its capital stock, (c) the number of
          issued and outstanding shares of each class of its capital stock,
          the names of the holders thereof and the number of shares held by
          each such holder and (d) the number of shares of its capital
          stock held in treasury (if any). Except as set forth on Schedule
          3.1( (b))((i))(1) to the AAC Disclosure Letter, all of the issued
          and outstanding shares of capital stock of each AAC Subsidiary
          have been duly authorized and are validly issued, fully paid and
          nonassessable. All of the issued and outstanding shares of
          capital stock of each AAC Subsidiary are owned of record and
          beneficially by AAC and/or by another AAC Subsidiary free and
          clear of any and all restrictions on transfer (other than
          restrictions under the Securities Act and state securities laws),
          taxes, mortgages, liens, encumbrances, charges, pledges,
          impositions, security interests, options, warrants, purchase
          rights, contracts, commitments, equities, claims and demands
          ("Liens"). There are no outstanding or authorized options,
          warrants, purchase rights, conversion rights, exchange rights or
          other contracts or commitments that could require AAC to sell,
          transfer or otherwise dispose of any capital stock of any of the
          AAC Subsidiaries or that could require any AAC Subsidiary to
          issue, sell or otherwise cause to become outstanding any of its
          own capital stock. There are no outstanding stock appreciation,
          phantom stock, profit participation or similar rights with
          respect to any AAC Subsidiary. There are no voting trusts,
          proxies or other agreements or understandings with respect to the
          voting of any capital stock of any AAC Subsidiary. Each AAC
          Subsidiary that is a corporation is duly incorporated and validly
          existing under the laws of its jurisdiction of incorporation and
          has the requisite corporate power and authority to carry on its
          business as now being conducted. Except for the AAC Subsidiaries
          set forth on Schedule 3.1( (b))((i))(1) to the AAC Disclosure
          Letter, which in the aggregate do not represent a material
          percentage of the total value of the AAC Subsidiaries taken as a
          whole, each AAC Subsidiary is duly qualified or licensed to do
          business and is in good standing in each jurisdiction in which
          the nature of its business or the ownership, leasing of its
          properties or management of properties for others makes such
          qualification or licensing necessary, other than in such
          jurisdictions where the failure to be so qualified or licensed,
          individually or in the aggregate, would not have an AAC Material
          Adverse Effect. Schedule 3.1( (b))((i))(2) to the AAC Disclosure
          Letter is a true and complete list of all corporations, other
          than the Subsidiaries, with respect to which AAC has owned or
          otherwise controlled, within the last five years, a majority of
          the outstanding voting securities (the "Former AAC Subsidiaries")
          and accurately sets forth for each Former AAC Subsidiary (a) its

               (ii) Schedule 3.1( (b))((ii))(3) to the AAC Disclosure
          Letter is a true and complete list of all corporations with
          respect to which AAC owns or otherwise controls, directly or
          indirectly through one or more subsidiaries, partnerships, joint
          ventures or other business associations, less than a majority of
          the outstanding voting securities (the "AAC Investees"). Schedule
          3.1( (b))((ii))(3) to the AAC Disclosure Letter accurately sets
          forth for each AAC Investee (a) its name and jurisdiction of
          incorporation, (b) the number of shares of authorized capital
          stock of each class of its capital stock and (c) the number of
          issued and outstanding shares of each class of its capital stock
          held by AAC. All of the issued and outstanding shares of capital
          stock of each AAC Investee owned by AAC have been duly authorized
          and are validly issued, fully paid and nonassessable. All of the
          issued and outstanding shares of capital stock of each AAC
          Investee are owned of record and beneficially by AAC and/or by
          another AAC Subsidiary free and clear of any and all Liens. There
          are no outstanding or authorized options, warrants, purchase
          rights, conversion rights, exchange rights or other contracts or
          commitments that could require AAC to sell, transfer or otherwise
          dispose of any capital stock of any of the AAC Investees. There
          are no voting trusts, proxies or other agreements or
          understandings with respect to the voting of any capital stock of
          any AAC Investee owned by AAC. Schedule 3.1( (b))((ii))(4) to the
          AAC Disclosure Letter is a true and complete list of all
          corporations, other than the AAC Investees, with respect to which
          AAC has owned or otherwise controlled, within the last five
          years, less than a majority of the outstanding voting securities
          (the "Former AAC Investees") and accurately sets forth for each
          Former AAC Investee (a) its name and jurisdiction of
          incorporation, (b) the nature and extent of AAC's interest in
          such Former AAC Investee, (c) the date such interest was disposed
          of and (d) the manner of such disposition.

          (c) AAC Partnerships. Schedule 3.1( (c))(1) to the AAC Disclosure
Letter is a true and complete list of all of the partnerships, joint
ventures, limited liability entities, trusts and other business
associations (the "AAC Partnerships" and together with AAC and the AAC
Subsidiaries, "AAC Entities") in which AAC and/or any AAC Subsidiary or AAC
Partnership is a participant and accurately sets forth (a) the name and
jurisdiction of organization of each AAC Partnership and (b) the nature and
extent of AAC's or any other owner's interest in each AAC Partnership. Such
interests in the AAC Partnerships are owned free and clear of any Liens.
Except for the AAC Partnerships set forth on Schedule 3.1(c)(1) to the AAC
Disclosure Letter, which in the aggregate do not represent a material
percentage of the total value of the AAC Partnerships taken as a whole,
each AAC Partnership is duly organized and validly existing under the laws
of its jurisdiction of organization and has the requisite power and
authority to carry on its business as now being conducted. Except for the
Entity Level Investments set forth on Schedule 3.1( (c))(2) to the AAC
Disclosure Letter, there are no outstanding contracts or commitments that
could require any of the AAC Partnerships to admit additional participants
or require any AAC Entity to sell, transfer or otherwise dispose of its
interest in any AAC Partnership. Schedule 3.1( (c))(3) to the AAC
Disclosure Letter is a true and complete list of all of the partnerships,
joint ventures and other business associations, other than the AAC
Partnerships, in which any AAC Entity has been a participant in the last
five years (the "Former AAC Partnerships") and accurately sets forth for
each Former AAC Partnership (a) the type of entity, (b) its name and
jurisdiction of organization, (c) the nature and extent of 


<PAGE>

any AAC Entity's interest in such Former AAC Partnership, (d) the date such
interest was disposed of and (e) the manner of such disposition. AAC does
not own, and has not within the last five years owned, any equity interest
in any entity except the AAC Subsidiaries, the Former AAC Subsidiaries, the
AAC Investees, the Former AAC Investees, the AAC Partnerships and the
Former AAC Partnerships.

          (d) Capital Structure. AAC has authority to issue 10,400,100

of Class A Nonvoting Common Stock, $.01 par value (the "AAC Nonvoting
Common Stock"), 10,000,000 shares of AAC Common Stock and 400,000 shares of
preferred stock, of which 300,000 are classified as AAC Preferred Stock and
100,000 are without class designation. On the date hereof, no shares of
Nonvoting AAC Common Stock, 853,968.26 shares of AAC Common Stock and
170,000 shares of AAC Preferred Stock were issued and outstanding. On the
date of this Agreement, except as set forth above in this Section 3.1 or in
a Schedule to the AAC Disclosure Letter referred to above in this Section
3.1, no shares of capital stock or other voting securities of AAC or any
AAC Subsidiary were issued, reserved for issuance or outstanding. All
outstanding shares of capital stock of AAC are duly authorized, validly
issued, fully paid and nonassessable and not subject to preemptive rights.
Except (A) for the AAC OP Units, (B) as set forth in Schedule 3.1( (d)) to
the AAC Disclosure Letter, and (C) as otherwise permitted under Section
4.1, there are no outstanding securities, options, stock appreciation
rights, warrants, calls, rights, commitments, agreements, arrangements or
undertakings of any kind to which AAC or any AAC Subsidiary is a party or
by which such entity is bound, obligating AAC or any AAC Subsidiary to
issue, deliver or sell, or cause to be issued, delivered or sold,
additional shares of capital stock, voting securities or other ownership
interests of AAC or any AAC Subsidiary or obligating AAC or any AAC
Subsidiary to issue, grant, extend or enter into any such security, option,

          (e) Authority; Noncontravention; Consents. AAC has the requisite
corporate power and authority to enter into this Agreement and to
consummate the Merger and the other transactions contemplated by this
Agreement. The execution and delivery of this Agreement by AAC and the
consummation by AAC of the transactions contemplated hereby to which AAC is
a party have been duly authorized and approved by the Board of Directors of
AAC in the manner required by AAC's Articles of Incorporation and Bylaws
and by applicable law. This Agreement has been duly executed and delivered
by AAC and constitutes a valid and binding obligation of AAC, enforceable
against AAC in accordance with its terms. Except as set forth in Schedule
3.1( (e)) to the AAC Disclosure Letter, the execution and delivery of this
Agreement by AAC does not, and the consummation of the transactions
contemplated hereby to which AAC is a party and compliance by AAC with the
provisions of this Agreement will not, conflict with, or result in any
violation of, or default (with or without notice or lapse of time, or both)
under, or give rise to a right of termination, cancellation or acceleration
of any obligation or to loss of a material benefit under, or result in the
creation of any Lien upon any of the properties or assets of AAC or any AAC
Subsidiary under, (i) the charter or bylaws or the comparable charter or
organizational documents or partnership or similar agreement (as the case
may be) of any AAC Entity, each as amended or supplemented to the date of
this Agreement, (ii) any loan or credit agreement, note, bond, mortgage,
indenture, lease or agreement to acquire real property, or any 


<PAGE>

other material contract, agreement, arrangement or understanding to which
any AAC Entity is a party or by which it or any of its properties is bound,
or (iii) subject to the governmental filings and other matters referred to
in the following sentence, any judgment, decree, statute, law, ordinance,
rule, regulation or order of any Governmental Entity (as defined herein)
(collectively, "Laws") applicable to any AAC Entity, or its respective
business, properties, operations or assets, other than, in the case of
clause (ii) or (iii), any such conflicts, violations, defaults, rights or
Liens that individually or in the aggregate would not (x) have an AAC
Material Adverse Effect or (y) prevent the consummation of the Merger or
the other transactions contemplated hereby. No consent, approval, order or
authorization of, or registration, declaration or filing with, any federal,
state or local government or any court, administrative or regulatory agency
or commission or other governmental authority or agency (a "Governmental
Entity") is required by or with respect to any AAC Entity in connection
with the execution and delivery of this Agreement by AAC or the
consummation by AAC of any of the transactions contemplated hereby and
thereby, except for (i) the filing of the Articles of Merger with the SDAT
and the VSCC, the acceptance for record of the Articles of Merger by the
SDAT and the issuance of a certificate of merger by the VSCC, (ii) such
filings as may be required in connection with the payment of any Transfer
and Gains Taxes (as defined herein) and (iii) such other consents,
approvals, orders, authorizations, registrations, declarations and filings
(A) as are set forth in Schedule 3.1( (e)) to the AAC Disclosure Letter,
(B) as may be required under federal, state, local or foreign Environmental
Laws (as defined herein), (C) as may be required under the "blue sky" laws
of various states or (D) which, if not obtained or made, would not prevent
or delay in any material respect the consummation of the Merger or the
other transactions contemplated hereby or otherwise prevent AAC from
performing its obligations under this Agreement in any material respect or
have, individually or in the aggregate, an AAC Material Adverse Effect. For
purposes of determining compliance with the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended (the "HSR Act"), AAC confirms that the
conduct of its business consists solely of investing in, owning, developing
and operating real estate for the benefit of its shareholders.

          (f) Financial Statements; Undisclosed Liabilities. The audited
consolidated financial statements and the notes thereto of AAC and of AACLP
for the years ended December 31, 1997 and 1996, the unaudited consolidated
financial statements and the notes thereto for the six months ended June
30, 1998 and the nine months ended September 30, 1998 if the Closing Date
occurs after September 30, 1998, copies of which have been heretofore
delivered by AAC and AACLP to the Company, except as noted therein, have
been prepared in accordance with GAAP and fairly present, in accordance
with the applicable requirements of GAAP, the consolidated financial
position of AAC and AACLP, each taken as a whole, as of the dates thereof
and the consolidated results of operations and cash flows for the periods
then ended (subject, in the case of interim financial statements, to normal
year-end adjustments). The Closing Balance Sheet, except as provided in
Section 2.2(a), will be prepared in accordance with GAAP. Except for
liabilities and obligations set forth in Schedule 3.1( (f)) to the AAC
Disclosure Letter, no AAC Entity has any liabilities or obligations not
reflected in the financial statements of any nature (whether accrued,
contingent or otherwise) required by GAAP to be set forth on a consolidated
balance sheet of AAC or in the notes thereto and that, individually or in
the aggregate, would have an AAC Material Adverse Effect.


<PAGE>

          (g) Absence of Certain Changes or Events. Except as disclosed in
Schedule 3.1( (g)) to the AAC Disclosure Letter, since the date of the most
recent audited financial statements of AAC (the "AAC Financial Statement
Date") and to the date of this Agreement, but not thereafter with respect
to clause (a) of this Section 3.1( (g)), the AAC Entities have conducted
their business only in the ordinary course and there has not been (a) any
material adverse change in the business, financial condition or results of
operations of the AAC Entities taken as a whole, that has resulted or would
result, individually or in the aggregate, in AAC Economic Losses (as
defined in Section 6.2(a) below) of $8,000,000 or more (an "AAC Material
Adverse Change"), nor has there been any occurrence or circumstance that
with the passage of time would reasonably be expected to result in an AAC
Material Adverse Change, (b) except for regular quarterly distributions of
the AAC Common Stock and the AAC Preferred Stock covering the period
through the Closing Date at a rate not to exceed in the aggregate on an
annual basis 9% of the value of the capital accounts of the AACLP partners,
any declaration, setting aside or payment of any dividend or other

issuance of an ownership interest in, any AAC Entity except as contemplated
by this Agreement, (d) any damage, destruction or loss, whether or not
covered by insurance, that has or would have an AAC Material Adverse
Effect, (e) any change in accounting methods, principles or practices by
any AAC Entity materially affecting its assets, liabilities or business,

AAC Disclosure Letter, and other than personal injury and other routine
tort litigation arising from the ordinary course of operations of the AAC
Entities that is covered by adequate insurance, there is no suit, action,
claim, proceeding or governmental investigation pending or threatened
against or affecting any AAC Entity that, individually or in the aggregate,
could reasonably be expected to (i) have an AAC Material Adverse Effect or
(ii) prevent the consummation of the Merger or any of the other
transactions contemplated hereby, nor is there any judgment, decree,
injunction, rule or order of any Governmental Entity or arbitrator
outstanding against any AAC Entity having, or that, insofar as reasonably
can be foreseen, in the future would have, any such effect.

          (i) Absence of Changes in Benefit Plans; ERISA Compliance.

               (i) Except as disclosed in Schedule 3.1( (i))((i)) to the
          AAC Disclosure Letter, since the date of the most recent audited
          financial statements of AAC, there has not been any adoption or
          amendment in any material respect by any AAC Entity of any bonus,
          pension, profit sharing, deferred compensation, incentive
          compensation, stock ownership, stock purchase, stock option,
          phantom stock, retirement, vacation, severance, disability, death
          benefit, hospitalization, medical or other employee benefit plan,



<PAGE>

          arrangement or understanding (whether or not legally binding)
          providing benefits to any current or former employee, officer or
          director of AAC or any AAC Subsidiary or any person affiliated
          with AAC under Section 414(b), (c), (m) or (o) of the Code
          (collectively, "AAC Benefit Plans").

               (ii) Except as described in Schedule 3.1( (i))((ii)) to the
          AAC Disclosure Letter or as would not have an AAC Material
          Adverse Change, (A) all AAC Benefit Plans, including any such
          plan that is an "employee benefit plan" as defined in Section
          3(3) of the Employee Retirement Income Security Act of 1974, as
          amended ("ERISA"), are in compliance with all applicable
          requirements of law, including ERISA and the Code and (B) no AAC
          Entity has any liabilities or obligations with respect to any
          such AAC Benefit Plan, whether accrued, contingent or otherwise
          (other than obligations to make contributions and pay benefits
          and administrative costs incurred in the ordinary course), nor
          are any such liabilities or obligations expected to be incurred.
          Except as set forth in Schedule 3.1( (i))((ii)) to the AAC
          Disclosure Letter, the execution of, and performance of the
          Transactions contemplated in, this Agreement will not (either
          alone or together with the occurrence of any additional or
          subsequent events) constitute an event under any AAC Benefit
          Plan, policy, arrangement or agreement, trust or loan that will
          or may result in any payment (whether of severance pay or
          otherwise), acceleration, forgiveness of indebtedness, vesting,
          distribution, increase in benefits or obligation to fund benefits
          with respect to any employee or director. The only severance
          agreements or severance policies applicable to the AAC Entities
          are the agreement and policies specifically referred to in
          Schedule 3.1( (i))((ii)) to the AAC Disclosure Letter.

          (j) Taxes.

               (i) Each AAC Entity has timely filed all Tax Returns (as
          defined herein) required to be filed by it (after giving effect
          to any filing extension properly granted by a Governmental Entity
          having authority to do so). Each such Tax Return is true, correct
          and complete in all material respects. Each AAC Entity has paid
          (or AAC has paid on its behalf), within the time and manner
          prescribed by law, all Taxes (as defined herein) that are due and
          payable. The most recent financial statements described in
          Section 3.1( (f)) reflect an adequate reserve for all taxes
          payable by the Company for all taxable periods and portions
          thereof accrued through the date of such Financial Statements. As
          of the date hereof, no AAC Entity has received notice that any
          federal, state and local income or franchise tax return of such
          AAC Entity has been or will be examined by any taxing authority.
          No AAC Entity has executed or filed with the Internal Revenue
          Service or any other taxing authority any agreement now in effect
          extending the period for assessment or collection of any income
          or other taxes. Except as disclosed on Schedule 3.1( (j))((i)) to
          the AAC Disclosure Letter, no AAC Entity is a party to any
          pending action or proceeding by any governmental authority for
          assessment or collection of taxes, and no claim for assessment or
          collection of taxes has been asserted against it. True, correct
          and complete copies of all federal, state and local income or
          franchise tax returns filed by each AAC Entity and all
          communications relating thereto have been delivered to the
          Company or made available to representatives of the Company. As
          used in this 


<PAGE>

          Agreement, "Taxes" shall mean any federal, state, local or
          foreign income, gross receipts, license, payroll, employment
          withholding, property, sales, excise or other tax or governmental
          charges of any nature whatsoever, together with any penalties,
          interest or additions thereto and "Tax Return" shall mean any
          return, declaration, report, claim for refund, or information
          return or statement relating to Taxes, including any schedule or
          attachment thereto, and including any amendment thereof.

               (ii) AAC (A) for all of its taxable years commencing with
          the year ended December 31, 1996 through December 31, 1997, has
          been subject to taxation as a real estate investment trust
          ("REIT") within the meaning of Section 856 of the Code and has
          satisfied the requirements to qualify as a REIT for such years,
          except with respect to the filing of AAC's 1997 Federal income
          tax return and the making of the applicable elections thereon (B)
          has operated, and intends to continue to operate, in such a
          manner as to qualify as a REIT for its tax year ending on the
          Effective Day and (C) has not taken or omitted to take any action
          that could reasonably be expected to result in a challenge to its
          status as a REIT, and no such challenge is pending or threatened.
          AAC has no undistributed earnings and profits allocable to any
          taxable period during which it or any predecessor in interest was
          subject to taxation as a corporation. AACLP has at all times, and
          each other AAC Entity that is a partnership or files Tax Returns
          as a partnership for federal income tax purposes has since its
          acquisition by AAC, been classified for federal income tax
          purposes as a partnership and not as a corporation or as an
          association taxable as a corporation. Each of the AAC
          Subsidiaries that is a corporation for federal income tax
          purposes is a "qualified REIT subsidiary" as defined in Section
          856(i) of the Code. No AAC Entity holds any asset (i) the
          disposition of which could be subject to rules similar to Section
          1374 of the Code as a result of an election under IRS Notice
          88-19 or (ii) that is subject to a consent filed pursuant to
          Section 341(f) of the Code and regulations thereunder.

               (iii) AAC has no reason to believe that any conditions exist
          that could reasonably be expected to prevent the Merger from
          qualifying as a reorganization within the meaning of Section
          368(a) of the Code.

          (k) No Loans or Payments to Employees, Officers or Directors.
Except as set forth in Schedule 3.1( (k)) to the AAC Disclosure Letter or
as otherwise specifically provided for in this Agreement, there is no (i)
loan outstanding from or to any employee or director, (ii) employment or
severance contract or other arrangement with respect to severance, (iii)
other agreement requiring payments to be made on a change of control or
otherwise as a result of the consummation of the merger or any of the other
transactions contemplated hereby with respect to any employee, officer or
director of any AAC Entity or (iv) any agreement to appoint or nominate any
person as a director of any AAC Entity.

          (l) Brokers. Other than Lazard, no broker, investment banker,
financial advisor or other person is entitled to any broker's, finder's,
financial advisor's or other similar fee or commission in connection with
the transactions contemplated hereby based upon arrangements made by or on
behalf of AAC or any AAC Subsidiary.

          (m) Compliance with Laws. Except as set forth in Schedule 3.1(
(m)) to the AAC Disclosure Letter, no AAC Entity has violated or failed to
comply in any material respect with any Law applicable to its business,
properties, operations or assets, except for violations and failures to
comply that would not, individually or in the aggregate, reasonably be
expected to result in an AAC Material Adverse Effect.

          (n) Contracts; Debt Instruments. No AAC Entity is in violation of
or in default under, in any material respect (nor does there exist any
condition which upon the passage of time or the giving of notice or both
would cause such a violation of or default under), any material loan or
credit agreement, note, bond, mortgage, indenture, lease, or any agreement
to acquire real property, or any other material contract, agreement,
arrangement or understanding, to which it is a party or by which it or any
of its properties or assets is bound ("Material Contracts"), except as set
forth in Schedule 3.1( (n)) to the AAC Disclosure Letter and except for
violations or defaults that would not, individually or in the aggregate,
result in an AAC Material Adverse Effect. Schedule 3.1( (n)) is a true and
complete list of all Material Contracts.

          (o) Environmental Matters. Except as disclosed in Schedule 3.1(
(o)) to the AAC Disclosure Letter or in the environmental audits/reports
listed thereon, each AAC Entity has obtained all material licenses,
permits, authorizations, approvals and consents from Governmental Entities
that are required in respect of its business, operations, assets or
properties under any applicable Environmental Law (as defined below) and
each AAC Entity is in compliance in all material respects with the terms
and conditions of all such licenses, permits, authorizations, approvals and
consents and with any applicable Law of any Governmental Entity relating to
human health, safety or protection of the environment ("Environmental
Laws"), except for violations and failures to comply, individually or in
the aggregate, that would not have an AAC Material Adverse Effect.

          (p) AAC Properties. Except as listed in Schedule 3.1( (p)) to the

the AAC Properties are not subject to any liens, mortgages, deeds of trust,

property, including zoning regulations, provided they do not materially
adversely affect the current use of the AAC Properties, (b) liens for real
estate taxes that are not yet due and payable, (c) mechanics', carriers',
workmen's, repairmen's liens and similar Encumbrances that have heretofore
been bonded or which individually or in the aggregate do not exceed
$100,000, do not materially detract from the value of or materially
interfere with the present use of any of the AAC Properties subject thereto
or affected thereby and do not otherwise materially impair business
operations conducted by the AAC Entities and which have arisen or been
incurred only in its construction activities or in the ordinary course of
business, (d) rights of parties in possession, (e) matters that would be
disclosed by an accurate survey, (f) existing mortgages or deeds of trust

policies covering the AAC Properties and any other, easements,
rights-of-way, restrictions (including zoning restrictions), matters of
plat, minor defects or irregularities in title, license or lease agreements

          The Company represents and warrants to AAC as follows:

          (a) Organization, Standing and Corporate Power of the Company.
The Company is a corporation duly organized and validly existing under the
laws of Virginia and has the requisite corporate power and authority to
carry on its business as now being conducted. The Company is duly qualified
or licensed to do business and is in good standing in each jurisdiction in
which the nature of its business or the ownership or leasing of its
properties makes such qualification or licensing necessary, other than in
such jurisdictions where the failure to be so qualified or licensed,
individually or in the aggregate, would not have a material adverse effect
on the business, properties, assets, financial condition or results of
operations of the Company and its Subsidiaries, taken as a whole (a
"Company Material Adverse Effect"). Each Company Subsidiary that is a
corporation is duly incorporated and validly existing under the laws of its
jurisdiction of incorporation and has the requisite corporate power and
authority to carry on its business as now being conducted and each Company
Subsidiary that is a partnership, limited 


<PAGE>

Subsidiary is duly qualified or licensed to do business and is in good
standing in each jurisdiction in which the nature of its business or the
ownership or leasing of its properties makes such qualification or
licensing necessary, other than in such jurisdictions where the failure to
be so qualified or licensed individually or in the aggregate, would not
have a Company Material Adverse Effect.

to purchase shares of Common Stock granted under the Company Plans (the
"Company Stock Options"). On the date of this Agreement, except as set
forth in this Section 3.2( (b)), no shares of capital stock or other voting
securities of the Company were issued, reserved for issuance or

               (ii) The Company has delivered to AAC complete and correct

               (iii) As of September 4, 1998, there were 13,415,221
          outstanding Company OP Units, of which the Company owned, either
          directly or indirectly, 11,296,871 Company OP Units.

          (d) Authority; Noncontravention; Consents. The Company has the
requisite corporate power and authority to enter into this Agreement and to
consummate the transactions contemplated by this Agreement to which the
Company is a party. The execution and delivery of this Agreement by the
Company and the consummation by the Company of the transactions
contemplated hereby to which the Company is a party have been duly
authorized and approved in the manner required by the Company Charter and
the Company's Bylaws, by applicable law or by applicable regulations of any
stock exchange or other regulatory body, and by the Company's Board of
Directors. No approval by the stockholders of the Company is required to
complete the Merger and the other transactions contemplated hereby,
including without limitation, under the rules of the NYSE. This Agreement
has been duly executed and delivered by the Company and constitutes a valid
and binding obligation of the Company, enforceable against the Company in
accordance with its terms. The execution and delivery of this Agreement by
the Company does not, and the consummation of the transactions contemplated
hereby to which the Company is a party and compliance by the Company with
the provisions of this Agreement will not, conflict with, or result in any
violation of, or default (with or without notice or lapse of time, or both)
under, or give rise to a right of termination, cancellation or acceleration
of any obligation or to loss of a material benefit under, or result in the
creation of any Lien upon any of the properties or assets of the Company or
any Company Subsidiary under, (i) the Company Charter or Company's Bylaws
or the comparable charter or organizational documents or partnership or
similar agreement (as the case may be) of any Company Subsidiary, each as
amended or supplemented to the date of this Agreement, (ii) any loan or
credit agreement, note, bond, mortgage, indenture, reciprocal easement
agreement, lease or other agreement, instrument, permit, concession,

filings and other matters referred to in the following sentence, any Laws
applicable to the Company or any Company Subsidiary or their respective
properties or assets, other than, in the case of clause (ii) or (iii), any
such conflicts, violations, defaults, rights or Liens that individually or
in the aggregate would not (x) have a Company Material Adverse Effect or
(y) prevent the consummation of the Merger or the other transactions
contemplated hereby. No consent, approval, order or authorization of, or
registration, declaration or filing with, any Governmental Entity is
required by or with respect to the Company or any Company Subsidiary in

or the consummation by the Company of any of the transactions contemplated
hereby and thereby, except for (i) the filing of the Articles of Merger
with the VSCC and the SDAT, (ii) the filing with the Securities and

<PAGE>

laws of various states or (D) which, if not obtained or made, would not
prevent or delay in any material respect the consummation of any of the
transactions contemplated by this Agreement or otherwise prevent the
Company from performing its obligations under this Agreement in any
material respect or have, individually or in the aggregate, a Company
Material Adverse Effect. For purposes of determining compliance with the
HSR Act, the Company confirms that the conduct of its business consists
solely of investing in, owning, developing and operating real estate for
the benefit of its shareholders and the unitholders of the Company
Operating Partnership.

          (e) SEC Documents; Financial Statements; Undisclosed Liabilities.
The Company has filed all required reports, schedules, forms, statements
and other documents with the SEC since January 1, 1994 through the date
hereof (the "Company SEC Documents"). Except for liabilities and
obligations set forth in the Company SEC Documents, neither the Company nor
any of the Company Subsidiaries has any liabilities or obligations of any
nature (whether accrued, contingent or otherwise) required by GAAP to be
set forth on a consolidated balance sheet of the Company or in the notes
thereto and which, individually or in the aggregate, would have a Company
Material Adverse Effect. All of the Company SEC Documents (other than
preliminary material), as of their respective filing dates, complied in all
material respects with all applicable requirements of the Securities Act of
1933, as amended (the "Securities Act"), and the Exchange Act and, in each
case, the rules and regulations promulgated thereunder applicable to such
Company SEC Documents. None of the Company SEC Documents at the time of
filing contained any untrue statement of a material fact or omitted to
state any material fact required to be stated therein or necessary in order
to make the statements therein, in light of the circumstances under which
they were made, not misleading, except to the extent such statements have
been modified or superseded by later Company SEC Documents filed and
publicly available prior to the date of this Agreement. There is no
unresolved violation, criticism or exception by any Governmental Entity of
which the Company has received written notice with respect to the Company
report or statement which, if resolved in a manner unfavorable to the
Company, could have a Company Material Adverse Effect. The consolidated
financial statements of the Company and the Company Subsidiaries included
in the Company SEC Documents complied as to form in all material respects
with applicable accounting requirements and the published rules and
regulations of the SEC with respect thereto, have been prepared in
accordance with GAAP (except, in the case of interim financial statements,
as permitted by the applicable regulations of the SEC) applied on a
consistent basis during the periods involved (except as may be indicated in
the notes thereto) and fairly presented, in accordance with the applicable
requirements of GAAP, the consolidated financial position of the Company
and the Company Subsidiaries, taken as a whole, as of the dates thereof and
the consolidated results of operations and cash flows for the periods then
ended (subject, in the case of interim financial statements, to normal
year-end adjustments). The Company has no Company Subsidiaries that are not
consolidated for accounting purposes.

          (f) Absence of Certain Changes or Events. Except as disclosed in
the Company SEC Documents or in Schedule 3.2( (f)) to the Company
Disclosure Letter, since the date of the most recent financial statements
included in the Company SEC Documents (the "Company Financial 


<PAGE>

Statement Date") and to the date of this Agreement, but not thereafter with
respect to clause (a) of this Section 3.2( (f)), the Company and the
Company Subsidiaries have conducted their business only in the ordinary
course and there has not been (a) any material adverse change in the
business, financial condition or results of operations of the Company and
the Company Subsidiaries taken as a whole, that has resulted or would
result, individually or in the aggregate, in Company Economic Losses (as
defined in Section 6.3 below) of $30,000,000 or more (a "Company Material
Adverse Change"), nor has there been any occurrence or circumstance that
with the passage of time would reasonably be expected to result in a
Company Material Adverse Change, (b) except for regular quarterly
distributions not in excess of $.30 per share of Common Stock (including
any corresponding distribution by the Company Operating Partnership) with
customary record and payment dates, any declaration, setting aside or
payment of any dividend or other distribution (whether in cash, stock or
property) with respect to any of the Common Stock, (c) any split,
combination or reclassification of any share of Common Stock or any
issuance or the authorization of any issuance of any other securities in
respect of, in lieu of or in substitution for, or giving the right to
acquire by exchange or exercise, shares of Common Stock or any issuance of
an ownership interest in, any Company Subsidiary except as contemplated by
this Agreement, (d) any damage, destruction or loss, whether or not covered
by insurance, that has or would have a Company Material Adverse Effect or
(e) any change in accounting methods, principles or practices by the
Company or any Company Subsidiary materially affecting its assets,
liabilities or business, except insofar as may have been disclosed in the
Company SEC Documents or required by a change in GAAP.

          (g) Litigation. Except as disclosed in Schedule 3.2( (g)) to the
Company Disclosure Letter, and other than personal injury and other routine
tort litigation arising from the ordinary course of operations of the
Company and the Company Subsidiaries that is covered by adequate insurance,
there is no suit, action, claim, proceeding or governmental investigation
pending or threatened against or affecting the Company or any Company
Subsidiary that, individually or in the aggregate, could reasonably be
expected to (i) have a Company Material Adverse Effect or (ii) prevent the
consummation of the Merger or any of the other transactions contemplated
hereby, nor is there any judgment, decree, injunction, rule or order of any
Governmental Entity or arbitrator outstanding against the Company or any
Company Subsidiary having, or that, insofar as reasonably can be foreseen,
in the future would have, any such effect.

          (h) Properties. (i) The Company or a Company Subsidiary owns fee
simple title or has a valid leasehold interest in each of the real
properties listed in the Company SEC Reports as owned by the Company (the
"Company Properties"), except where failure to own such title would not
have a Company Material Adverse Effect; (ii) the Company Properties are not
subject to any Encumbrances or Property Restrictions that could cause a
Company Material Adverse Effect; (iii) valid policies of title insurance
have been issued insuring the Company's or the applicable Company
Subsidiaries' fee simple title to the Company Properties, except where
failure to obtain such title insurance would not have a Company Material
Adverse Effect; (iv) there is no certificate, permit or license from any
Governmental Authority having jurisdiction over any of the Company
Properties that has not been obtained where such failure to obtain would
have a Company Material Adverse Effect, or any pending threat of
modification or cancellation of any of same that would have a Company
Material Adverse Effect; (v) neither the 


<PAGE>

Company nor a Company Subsidiary has received any written notice of any
violation of any federal, state or municipal law, ordinance, order,
regulation or requirement affecting any of the Company Properties issued by
any Governmental Authority that would have a Company Material Adverse
Effect; (vi) neither the Company nor a Company Subsidiary has received any
written notice to the effect that (a) condemnation or rezoning proceedings
are pending or threatened with respect to any of the Company Properties or
(b) zoning, building or similar laws, codes, ordinances, orders or
regulations are or will be violated by the continued maintenance, operation
or use of any buildings or other improvements on any of the Company
Properties or by the continued maintenance, operation or use of the parking
areas, other than notices that, in the aggregate, would not have a Company
Material Adverse Effect.

          (i) Environmental Matters. The Company and each Company
Subsidiary have obtained all material licenses, permits, authorizations,
approvals and consents from Governmental Entities that are required in
respect of their business, operations, assets or properties under any
applicable Environmental Law and the Company and each Company Subsidiary
are in compliance in all material respects with the terms and conditions of
all such licenses, permits, authorizations, approvals and consents and with
any Environmental Laws, except for violations and failures to comply,
individually or in the aggregate, that would not have a Company Material
Adverse Effect.

          (j) Taxes.

               (i) The Company and each Company Subsidiary have timely
          filed all Tax Returns required to be filed by them (after giving
          effect to any filing extension properly granted by a Governmental
          Entity having authority to do so). Each such Tax Return is true,
          correct and complete in all material respects. The Company and
          each Company Subsidiary have paid (or the Company has paid on
          their behalf), within the time and manner prescribed by law, all
          Taxes that are due and payable. The most recent financial
          statements contained in the Company SEC Documents reflect an
          adequate reserve for all taxes payable by the Company for all
          taxable periods and portions thereof accrued through the date of
          such financial statements. Neither the Company nor any Company
          Subsidiary has received notice that any federal, state and local
          income or franchise tax return of the Company or any Company
          Subsidiary has been or will be examined by any taxing authority.
          Neither the Company nor any Company Subsidiary has executed or
          filed with the Internal Revenue Service or any other taxing
          authority any agreement now in effect extending the period for
          assessment or collection of any income or other taxes. Neither
          the Company nor any Company Subsidiary is a party to any pending
          action or proceeding by any governmental authority for assessment
          or collection of taxes, and no claim for assessment or collection
          of taxes has been asserted against it, which, individually or in
          the aggregate, would not have a Company Material Adverse Effect.

               (ii) The Company (A) for all of its taxable years commencing
          with the year ended December 31, 1993 through December 31, 1997,
          has been subject to taxation as a REIT within the meaning of
          Section 856 of the Code and has satisfied the requirements to
          qualify as a REIT for such years, (B) has operated, and intends
          to continue to operate,

<PAGE>

          in such a manner as to qualify as a REIT for its tax year ending
          December 31, 1998 and (C) has not taken or omitted to take any
          action that could reasonably be expected to result in a challenge
          to its status as a REIT, and no such challenge is pending or
          threatened. The Company represents that each of its corporate
          Company Subsidiaries is a Qualified REIT Subsidiary as defined in
          Section 856(i) of the Code, and that each partnership, limited
          liability company, joint venture or other legal entity in which
          the Company (either directly or indirectly) owns any of the
          capital stock or other equity interests thereof has been treated
          since its formation and continues to be treated for federal
          income tax purposes as a partnership and not as an association
          taxable as a corporation.

               (iii) The Company has no reason to believe that any
          conditions exist that could reasonably be expected to prevent the
          Merger from qualifying as a reorganization within the meaning of
          Section 368(a) of the Code.

          (k) Brokers. Except for Morgan Stanley, Dean Witter & Co., no
broker, investment banker, financial advisor or other person is entitled to
any broker's, finder's, financial advisor's or other similar fee or
commission in connection with the transactions contemplated hereby based
upon arrangements made by or on behalf of the Company or any Company
Subsidiary.

          (l) Compliance with Laws. Neither the Company nor any Company
Subsidiary has violated or failed to comply with any Law applicable to its
business, properties, operations or assets, except for violations and
failures to comply that would not, individually or in the aggregate,
reasonably be expected to result in a Company Material Adverse Effect.

          (m) Contracts; Debt Instruments. Neither the Company nor any
Company Subsidiary is in violation of or in default under, in any material
respect (nor does there exist any condition which upon the passage of time
or the giving of notice or both would cause such a violation of or default
under), any Material Contracts, except for violations or defaults that
would not, individually or in the aggregate, result in a Company Material
Adverse Effect.

          (n) State Takeover Statutes. The Company has taken all action
necessary to exempt transactions between the Company and the AAC Entities
from the operation of any "fair price," "moratorium," "control share
acquisition" or any other anti-takeover statute or similar statute enacted
under the state or federal laws of the United States or similar statute or
regulation.

          (o) Investment Company Act of 1940. Neither the Company nor any
Company Subsidiary is, or at the Effective Time, will be, required to be
registered under the Investment Company Act.

          (p) Company Not an Interested Shareholder. The Company is not an
"interested stockholder" of AAC or an "affiliate of an interested
stockholder" of AAC within the meaning of Section 3601 of the MGCL.

respective Subsidiaries not to take any action that would result in (i) any
of the representations and warranties of such party set forth in this
Agreement that are qualified as to materiality becoming untrue in any
material respect, (ii) any of such representations and warranties that are
not so qualified becoming untrue in any respect or (iii) any of the

                            ADDITIONAL COVENANTS


          Section 5.1. Access to Information; Confidentiality.

          Subject to the requirements of confidentiality agreements with
third parties, each of AAC and the Company shall, and shall cause each of
its respective Subsidiaries to, afford to the other party and to the
officers, employees, accountants, counsel, financial advisors and other
representatives of such other party, reasonable access during normal
business hours during the period prior to the Effective Time to all their
respective properties, books, contracts, commitments, personnel and records
and, during such period, each of AAC and the Company shall, and shall cause
each of its respective Subsidiaries to, furnish promptly to the other party
(a) a copy of each report, schedule, registration statement and other
document filed by it during such period pursuant to the requirements of
federal or state securities laws and (b) all other information concerning
its business, properties and personnel as such other party may reasonably
request. Each of AAC and the Company will hold, and will cause its
respective Subsidiaries' officers, employees, accountants, counsel,
financial advisors and other representatives and affiliates to hold, any
nonpublic information in confidence to the extent required by, and in
accordance with, and will comply with the provisions of the letter
agreement between AAC and the Company dated as of August 6, 1998 (the
"Confidentiality Agreement").

          Section 5.2. Best Efforts; Notification.

          (a) Upon the terms and subject to the conditions set forth in
this Agreement, each of the Company and AAC agrees to use its best efforts
to take, or cause to be taken, all actions, and to do, or cause to be done,
and to assist and cooperate with the other in doing, all things necessary,
proper or advisable to fulfill all conditions applicable to such party
pursuant to this Agreement and to consummate and make effective, in the
most expeditious manner practicable, the Merger and the other transactions
contemplated hereby, including (i) the obtaining of all necessary actions
or nonactions, waivers, consents and approvals from Governmental Entities
and the making of all necessary registrations and filings and the taking of
all reasonable steps as may be necessary to obtain an approval, waiver or
exemption from, or to avoid an action or 


<PAGE>

proceeding by, any Governmental Entity, (ii) the obtaining of all necessary
consents, approvals, waivers or exemption from shareholders and
non-governmental third parties; provided, however, that if AAC is obliged
to pay or incur any material expenses or other liabilities to obtain the
consent of any non-governmental party, it shall consult reasonably with the
Company upon reasonable notice prior to paying or incurring any such
material expenses or liabilities, and in no event shall AAC pay or incur
any such expenses or liabilities in obtaining such consents without
obtaining the prior written consent of the Company, which consent shall not
unreasonably be withheld or delayed, (iii) the defending of any lawsuits or
other legal proceedings, whether judicial or administrative, challenging
the Merger, this Agreement or the consummation of any of the other
transactions contemplated hereby, including seeking to have any stay or
temporary restraining order entered by any court or other Governmental
Entity vacated or reversed and (iv) the execution and delivery of any
additional instruments necessary to consummate the transactions
contemplated by and to fully carry out the purposes of, this Agreement;
provided, however, that a party shall not be obligated to take any action
pursuant to the foregoing if the taking of such action or the obtaining of
any waiver, consent, approval or exemption is reasonably likely to result
in the imposition of a condition or restriction of the type referred to in
Section 6.1( (b)). In connection with and without limiting the foregoing,
AAC, the Company and their respective Boards of Directors shall (i) take
all action necessary so that no "fair price," "business combination,"
"moratorium," "control share acquisition" or any other anti takeover
statute or similar statute enacted under state or federal laws of the
United States or similar statute or regulation (a "Takeover Statute") is or
becomes applicable to the Merger, this Agreement or any of the other
transactions contemplated hereby and (ii) if any Takeover Statute becomes
applicable to the Merger, this Agreement, or any of the other transactions
contemplated hereby, take all action necessary so that the Merger may be
consummated as promptly as practicable on the terms contemplated by this
Agreement and otherwise to minimize the effect of such Takeover Statute on
the Merger or the consummation of any of the other transactions
contemplated hereby.

          (b) AAC shall give prompt notice to the Company, and the Company
shall give prompt notice to AAC, if (i) any representation or warranty made
by it contained in this Agreement that is qualified as to materiality
becomes untrue or inaccurate in any material respect or any such
representation or warranty that is not so qualified becomes untrue or
inaccurate in any respect or (ii) it fails to comply with or satisfy in any
material respect any covenant, condition or agreement to be complied with
or satisfied by it under this Agreement; provided, however, that no such
notification shall affect the representations, warranties, covenants or
agreements of the parties or the conditions to the obligations of the
parties under this Agreement.

          Section 5.3. Tax Treatment.

          Each of the Company and AAC shall use its reasonable best efforts
to (a) cause the Merger to qualify as a reorganization under Section 368(a)
of the Code and (b) to obtain the opinions of counsel referred to in
Section 6.2( (e)) and 6.3( (d)).

director, employee, agent, investment banker, financial advisor, attorney,
accountant, broker, finder or other representative, initiate, solicit
(including by way of furnishing nonpublic information or assistance) any
inquiries or the making of any proposal that constitutes, or may reasonably
be expected to lead to, any Competing Transaction (as defined herein), or
authorize or permit any of its officers, directors, employees or agents,
attorneys, investment bankers, financial advisors, accountants, brokers,
finders or other representatives to take any such action. AAC shall notify
the Company in writing (as promptly as practicable) of all of the relevant
details relating to all inquiries and proposals which it or any of its
Subsidiaries or any such officer, director, employee, agent, investment
banker, financial advisor, attorney, accountant, broker, finder or other
representative may receive relating to any of such matters and if such
inquiry or proposal is in writing, AAC shall deliver to the other a copy of
such inquiry or proposal. For purposes of this Agreement, "Competing
Transaction" shall mean any of the following (other than the transactions
contemplated by this Agreement): (i) any merger, consolidation, share
exchange, business combination, or similar transaction involving AAC (or
any of its Subsidiaries); (ii) any sale, lease, exchange, mortgage, pledge,
transfer or other disposition of 50% or more of the assets of AAC and its
Subsidiaries taken as a whole in a single transaction or series of related
transactions, excluding any bona fide financing transactions which do not,
individually or in the aggregate, have as a purpose or effect the sale or
transfer of control of such assets; (iii) any tender offer or exchange
offer for 30% or more of the outstanding shares of capital stock of AAC (or
any of its Subsidiaries) or the filing of a registration statement under
the Securities Act in connection therewith; or (iv) any public
announcements of a proposal, plan or intention to do any of the foregoing
or any agreement to engage in any of the foregoing.

          Section 5.5. Public Announcements.

          The Company and AAC will consult with each other before issuing,
and provide each other the opportunity to review and comment upon, any
press release or other public statements with respect to the Merger or the
other transactions contemplated hereby, and shall not issue any such press
release or make any such public statement prior to such consultation,
except as may be required by applicable law, court process or by
obligations pursuant to any listing agreement with any national securities
exchange. The parties agree that the initial press release to be issued
with respect to the Merger will be in the form agreed to by the parties
hereto prior to the execution of this Agreement.

          Section 5.6. Transfer and Gains Taxes.

          The Company and AAC shall cooperate in the preparation, execution
and filing of all returns, questionnaires, applications or other documents
regarding any real property transfer or gains, sales, use, transfer, value
added, stock transfer and stamp taxes, any transfer, recording,
registration and other fees and any similar taxes which become payable in
connection with the Merger (together with any related interests, penalties
or additions to tax, "Transfer and Gains Taxes"). AAC shall pay or cause to
be paid, without deduction or withholding from any 


<PAGE>

amounts payable to the holders of shares of AAC Nonvoting Common Stock, AAC
Common Stock and AAC Preferred Stock all Transfer and Gains Taxes.

          Section 5.7. Employee Matters.

          AACLP (or the applicable AAC Entity) shall terminate all of its
employees prior to the Closing Date in compliance with (to the extent
applicable) the Worker Adjustment, Retraining and Notification Act of 1988,
as amended, including the giving of any notice thereunder, and under any
applicable state laws requiring the giving of notice of terminations,
layoffs, site closings or other comparable events. AACLP (or the applicable
AAC Entity) shall satisfy all severance pay, vacation pay and other legal
obligations with respect to its employees, including but not limited to any
obligations under any employment contracts or employee benefit plans or
programs, to the extent based on employment service rendered to AAC or any
AAC Entity prior to the Closing Date. The Company shall have no liability
or obligation to the AAC Entities or their employees to employ or offer
employment to any employee of the AAC Entities or any group of employees of
the AAC Entities. It is understood, however, that on or after the Closing
Date, the Company may, in its sole and absolute direction, offer employment
to those employees of AAC and the AAC Subsidiaries who, prior to Closing
Date, worked as site employees. Nothing in this Agreement shall limit the
Company from taking any action at any time after the Closing Date in
respect of its employees or the terms and conditions of their employment.

          Any former employees of the AAC Entities ("Former AAC Employees")
that are subsequently employed by the Company shall in general receive
compensation on the same basis and subject to same standards as the
employees of the Company. In addition, all Former AAC Employees shall be
eligible to participate in the same manner as other similarly situated
employees of the Surviving Corporation who were formerly employees of the
Company in any other benefit programs, policies and arrangements sponsored
or maintained by the Surviving Corporation after the Effective Time. With
respect to each such employee benefit plan, program, policy or arrangement,
service with AAC or any of the AAC Subsidiaries (as applicable) shall be
included for purposes of determining eligibility to participate, vesting
(if applicable) and entitlement to benefits. The medical plan or plans
maintained by the Surviving Corporation after the Effective Time shall
waive all limitation as to preexisting conditions, exclusions and waiting
periods with respect to participation and coverage requirements applicable
to Former AAC Employees.

          Section 5.8. Disposition of Benefit Plans.

          As of the Closing Date, sponsorship of all AAC Benefit Plans
shall be assumed by American Apartment Communities III, L.P. ("AAC III"),
which shall thereafter be responsible for the administration of such plans.
AAC III may terminate any such plans, provided that it may, in its sole
discretion in the case of the AAC 401(k) Plan, transfer into the
corresponding plan or plans of the Surviving Corporation assets and
liabilities attributable to Former AAC Employees in a manner consistent
with Section 414(l) of the Code.

          Section 5.9. Company Board of Directors.

          At the Effective Time, the Board of Directors of the Company
shall be expanded by two members, and the existing directors of the Company
shall elect James D. Klingbeil and Robert P. Freeman as directors to serve
until the annual meeting of shareholders of the Company in 1999. Any
shareholder of AAC of record on the Effective Date (the "Holder") who
Beneficially Owns on the record date for determination of shareholders of
the Company entitled to vote at any annual meeting of shareholders or other
meeting at which the Board of Directors is elected (the "Record Date")
shares of Preferred Stock or shares of Common Stock received upon
conversion of Preferred Stock ("Conversion Stock"), or a combination,
having an aggregate Nominal Value, as defined below, of $150,000,000, shall
have the right to nominate two persons for election to the Company's Board
of Directors. In the event that the Holder Beneficially Owns on the Record
Date shares of Preferred Stock or Conversion Stock having a Nominal Value
of less than $150,000,000 but more than $100,000,000, the Holder shall have
the right to nominate one person for election to the Company's Board of
Directors. The Holder shall have the right to nominate the replacement for
any director nominated by it who shall not, for any reason, serve the
entirety of his or her term. The Holder shall make its nominations in
consultation with the Company's incumbent Board of Directors, provided that
at any time at which the Holder shall have the right to nominate two
persons for election to the Company Board of Directors, if at such time
James D. Klingbeil is nominated for reelection by the incumbent Board of
Directors pursuant to Section 2 of the Exchange Agreement or otherwise, he
shall be deemed one of the persons nominated by the Holder. "Nominal Value"
shall be calculated by valuing each share of Preferred Stock at its
liquidation preference as set forth in the Company's Articles of
Incorporation and each share of Conversion Stock at the liquidation
preference of the number of shares of Preferred Stock, or fraction thereof,
from which such Common Stock was converted. No director nominated by a
Holder shall be required to resign from the Board of Directors solely as a
result of a decline in the Nominal Value of the shares Beneficially Owned
by the Holder at any time during the term of such director.

          Section 5.10. Resignations.

          On the Closing Date, AAC shall cause the directors and officers
of each of the AAC Subsidiaries to submit their resignations from such
positions, effective as of the Effective Time.

          Section 5.11. Bulk Sales Compliance.

          The AAC Entities shall indemnify the Company and the Company
Operating Partnership from and against any and all claims, losses or
liabilities arising under any applicable bulk sales law in connection with
the transactions contemplated in this Agreement and the Exchange Agreement.

          Section 5.12. Financial Statements.

          AAC shall cause to be prepared in a form acceptable to the
Company consolidated financial statements of AAC and of AACLP for the years
ended December 31, 1997 and 1996 (audited) and for the six months ended
June 30, 1998 and 1997 and, if the Closing Date occurs 


<PAGE>

after September 30, 1998, the nine months ended September 30, 1998, except
as noted therein, in accordance with GAAP and fairly presenting, in
accordance with the applicable requirements of GAAP, the consolidated
financial position of AAC and AACLP, each taken as a whole, as of the dates
thereof and the consolidated results of operations and cash flows for the
periods then ended (subject, in the case of interim financial statements,
to normal year-end adjustments).

          Section 5.13. Executive Clubs.

          Prior to Closing, AAC shall cause AACLP to deal with the
properties known as the Arlington Executive Club and the Alexandria
Executive Club in a manner satisfactory to the Company in its sole
discretion.

          Section 5.14. AAC Office Leases.

          AAC shall or shall cause each other AAC Entity to transfer all
leases of which AAC or any AAC Entity is the lessee of commercial office
properties used in the conduct of their respective business.

respect of or filings with any Governmental Entity required for the

          Section 6.2. Conditions to Obligations of the Company.

          The obligations of the Company to effect the Merger and to
consummate the other transactions contemplated hereby are further subject
to the following conditions, any one or more of which may be waived by the
Company:

          (a) Representations and Warranties. The representations and
warranties of AAC set forth in this Agreement shall be true and correct as
of the Closing Date, as though made on and as of the Closing Date, except
to the extent the representation or warranty is expressly limited by its
terms to another date and except to the extent the representation or
warranty is rendered incorrect as a result of the reverse stock split
contemplated by Section 4.1(a), and the Company shall have received a
certificate signed on behalf of AAC by the chief executive officer or the
chief financial officer of AAC to such effect. This condition shall be
deemed satisfied notwithstanding any failure of a representation or
warranty of AAC to be true and correct as of the Closing Date if the
aggregate amount of AAC Economic Losses (as defined herein) that would
reasonably be expected to arise as a result of the failures of such
representations and warranties to be true and correct as of the Closing
Date does not exceed $8,000,000. "AAC Economic Losses" shall mean any and
all net damage, net loss, net liability or expense suffered by the AAC
Entities taken as a whole.

          (b) Financial Statements AAC shall have provided to the Company
the consolidated financial statements of AAC and AACLP, as described in
Section 3.1( (f)), prepared in a form acceptable to the Company and in
accordance with GAAP (audited for each of the years ended December 31, 1997
and 1996) and in conformity with Regulation S-X of the SEC and otherwise
adequate in form and substance to enable the Company to comply with its
reporting obligations under the Exchange Act with respect to its
acquisition of AAC and AACLP.

          (c) Performance of Obligations of AAC. AAC shall have performed

shall have received a certificate to such effect signed on behalf of AAC by
the chief executive officer or the chief financial officer of AAC.

          (d) Opinions Relating to REIT and Partnership Status. The Company
shall have received an opinion dated as of the Closing Date of Porter,
Wright, Morris & Arthur, based on certificates, letters and assumptions,
reasonably satisfactory to the Company, that (i) commencing with the year
ended December 31, 1996 through the Effective Date, AAC has been organized,
in conformity with the requirements for qualification as a REIT under the
Code, and its method of operation has enabled it to meet such requirements,
and (ii) AACLP has been since its year of formation, and each AAC
Subsidiary that is a partnership or limited liability company has been
since its formation, treated, for federal income tax purposes, as a
partnership 


<PAGE>

and not as a corporation or an association taxable as a corporation (with
customary exceptions, assumptions and qualifications and based upon
customary representations).

          (e) Opinions Relating to Merger. The Company shall have received
an opinion dated as of the Closing Date of Hunton & Williams, based on
certificates, letters and assumptions, reasonably satisfactory to the
Company, that (i) the Merger will be treated for Federal income tax

necessary in connection with the consummation of the Merger and the other

other transactions contemplated hereby is further subject to the following
conditions, any one or more of which may be waived by AAC:

          (a) Representations and Warranties. The representations and
warranties of the Company set forth in this Agreement shall be true and

Date, except to the extent the representation or warranty is expressly
limited by its terms to another date, and AAC shall have received a
certificate signed on behalf of the Company by the chief executive officer
or the chief financial officer of the Company to such effect. This
condition shall be deemed satisfied notwithstanding any failure of a
representation or warranty of the Company to be true and correct as of the
Closing Date if the aggregate amount of Company Economic Losses (as defined
herein) that would reasonably be expected to arise as a result of the
failures of such representations and warranties to be true and correct as
of the Closing Date does not exceed $30,000,000. "Company Economic Losses,"
as used in this Section 6.3, shall mean any and all net damage, net loss,
net liability or expense suffered by the Company or the Company
Subsidiaries taken as a whole.

          (b) Performance of Obligations of the Company. The Company shall
have performed in all material respects all obligations required to be

of such party to such effect.

          (c) Opinions Relating to REIT and Partnership Status. AAC and the
limited partners of AACLP shall have received an opinion dated as of the
Closing Date of Hunton & Williams, based on certificates, letters and
assumptions, reasonably satisfactory to AAC, that (i) commencing with the
taxable year ended December 31, 1993, the Company has been organized and
has operated, and its proposed method of operation following the Merger
will permit it to continue to be organized and operated, in conformity with
the requirements for qualification as a REIT under the Code and (ii) the
Company Operating Partnership has been during and since 1995, and continues
to be, treated for federal income tax purposes as a partnership and not as
a corporation or association taxable as a corporation (with customary
exceptions, assumptions and qualifications and based upon customary
representations).

          (d) Opinion Related to the Merger. AAC shall have received an
opinion dated as of the Closing Date of GD&C, based on certificates,
letters and assumptions, reasonably 

<PAGE>

satisfactory to AAC, that (i) the Merger will be treated for Federal income
tax purposes as a reorganization within the meaning of Section 368(a) of
the Code, (ii) the Company and AAC will each be a party to that
reorganization within the meaning of Section 368(b) of the Code, (iii) no
gain or loss will be recognized for federal income tax purposes by the
Company or AAC on consummation of the Merger and (iv) the exchange in the
Merger of Preferred Stock (including any fractional share interest) and
cash for capital stock of AAC will give rise to the recognition of gain
(but not loss) to the shareholders of AAC with respect to such exchange to
the extent of cash received in such exchange.

          (e) Consents. All consents and waivers from third parties
necessary in connection with the consummation of the other transactions
contemplated hereby shall have been obtained, other than such consents and
waivers from third parties, which, if not obtained, would not result,
individually or in the aggregate, in Company Economic Losses of $30,000,000
or more.

          (f) Corporate Matters Opinion. AAC shall have received the
opinion of Hunton & Williams, dated as of the Closing Date, as to such
customary matters as AAC may reasonably request, such opinion to be
reasonably satisfactory to AAC.

          (g) Investment Agreements. The Company shall have executed and
delivered investment agreements with the shareholders of AAC who receiver
Merger Consideration including shares of Preferred Stock.

          (h) No Material Adverse Change. From the date of this Agreement
through the Effective Time, no change on the business, properties, assets
financial condition or results of operations of the Company and/or the
Company Operating Partnership has occurred that would have or would be
reasonably likely to have a Company Material Adverse Effect.

          (i) Listing. The Company shall have caused the Common Stock
issuable upon the conversion of the Company Series D Preferred Stock and
the transactions contemplated by the Exchange Agreement, respectively, to
be approved for listing on the NYSE, subject to official notice of
issuance.

          (a) by mutual written consent duly authorized by the respective
Boards of Directors of the Company and AAC;


<PAGE>

          (b) by the Company, upon a material breach of any representation,
warranty, covenant or agreement on the part of AAC set forth in this
Agreement, or if any representation or warranty of AAC shall have become
untrue, in either case such that the conditions set forth in Section 6.2(
(a)) or Section 6.2( (c)), as the case may be, would be incapable of being
satisfied by December 31, 1998 (as otherwise extended);

          (c) by AAC, upon a material breach of any representation,
warranty, covenant or agreement on the part of the Company set forth in
this Agreement, or if any representation or warranty of the Company shall
have become untrue, in either case such that the conditions set forth in
Section 6.3( (a)) or Section 6.3( (b)) as the case may be, would be
incapable of being satisfied by December 31, 1998 (as otherwise extended);

          (d) by either the Company or AAC, if any judgment, injunction,
order, decree or action by any Governmental Entity of competent authority
preventing the consummation of the Merger shall have become final and
nonappealable; and

          (e) by either the Company or AAC, if the Merger shall not have
been consummated before December 31, 1998; provided, however, that a party
that has willfully and materially breached a representation, warranty or
covenant of such party set forth in this Agreement shall not be entitled to
exercise its right to terminate under this Section 7.1( (e)).

          Section 7.2. [LEFT BLANK INTENTIONALLY]

          Section 7.3. Effect of Termination.

          In the event of termination of this Agreement by either AAC or
the Company as provided in Section 7.1, this Agreement shall forthwith
become void and have no effect, without any liability or obligation on the

Section 5.5, this Section 7.3, Sections 8.2, 8.3, 8.5 through 8.10 and
Article IX and except to the extent that such termination results from a
willful breach by a party of any of its representations, warranties,
covenants or agreements set forth in this Agreement.

          Section 7.4. Amendment.

          At any time prior to the filing of the Articles of Merger with
the SDAT and the VSCC, this Agreement may be amended by the parties in
writing by action of their respective Boards of Directors, provided that
any such amendment approved by the Board of Directors of AAC after this
Agreement has been approved by the stockholders of AAC must also be
approved by such stockholders if such amendment would modify materially the
terms of Section 2.1 or modify any other provision of this Agreement so as
to adversely affect any class of shares of AAC. The parties agree to amend
this Agreement in the manner provided in the immediately preceding sentence
to the extent required to (a) continue the status of the parties as REITs
or (b) preserve the Merger as a tax-free reorganization under Section 368
of the Code.


<PAGE>

obligations or other acts of the other party, (b) waive any inaccuracies in
the representations and warranties of the other party contained in this
Agreement or in any document delivered pursuant to this Agreement or (c)
subject to the proviso of Section 7.4, waive compliance with any of the
agreements or conditions of the other party contained in this Agreement.
Any agreement on the part of a party to any such extension or waiver shall
be valid only if set forth in an instrument in writing signed on behalf of
such party. The failure of any party to this Agreement to assert any of its
rights under this Agreement or otherwise shall not constitute a waiver of
those rights.

                                ARTICLE VIII

                             GENERAL PROVISIONS

of the parties which by its terms contemplates performance after the
Effective Time.

               the event of any liquidation, dissolution or winding up of
               the corporation, the Series D Preferred shall rank on a

               Period shall be computed on the basis of a 360-day year

               Date"), whether or not (i) the corporation has earnings,
               (ii) dividends on such shares are declared or (iii) on any
               Dividend Payment Date there shall be funds legally available
               for the payment of such dividends. When dividends are not
               paid in full upon the shares of Series D Preferred and the
               shares of any other series of preferred stock ranking on a
               parity


<PAGE>


               as to dividends with the Series D Preferred (or a sum
               sufficient for such full payment is not set apart therefor),
               all dividends declared upon shares of Series D Preferred and
               any other series of preferred stock ranking on a parity as
               to dividends with the Series D Preferred shall be declared
               pro rata so that the amount of dividends declared per share
               on the Series D Preferred and such other series of preferred
               stock shall in all cases bear to each other the same ratio
               that accrued dividends per share on the shares of Series D
               Preferred and such other series of preferred stock bear to
               each other. "Business Day" shall mean any day, other than a
               Saturday or Sunday, that is neither a legal holiday nor a
               day on which banking institutions in New York City, New York
               are authorized or required by law, regulation or executive
               order to close.

                    (B) Except as provided in subparagraph (A) of this
               paragraph (3), unless full cumulative dividends on the
               Series D Preferred have been or contemporaneously are
               declared and paid or declared and a sum sufficient for the
               payment thereof set apart for payment on the Series D
               Preferred for all past dividend periods and the then current
               dividend period, no dividends (other than in Junior Stock)
               shall be declared or paid or set aside for payment or other
               distribution or shall be declared or made upon any Parity
               Stock or Junior Stock, nor shall any Junior Stock or any
               Parity Stock 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
               shares of Junior Stock or Parity Stock) by the corporation
               or any subsidiary of the corporation (except by conversion
               into or exchange for Junior Stock).

                    (C) Any dividend payment made on shares of the Series D
               Preferred shall first be credited against the earliest
               accrued but unpaid dividend due with respect to such shares
               which remains payable.

                    The amount of any dividends accrued on any shares of
               Series D Preferred at any Dividend Payment Date shall be the
               amount of any unpaid dividends accumulated thereon, to and
               including such Dividend Payment Date, whether or not earned
               or declared, and the amount of dividends accrued on any
               shares of Series D Preferred at any date other than a
               Dividend Payment Date shall be equal to the sum of the
               amount of any unpaid dividends accumulated thereon, to and
               including the last preceding Dividend Payment Date, whether
               or not earned or declared, plus an amount calculated on the
               basis of the annual dividend rate for the period after such
               last preceding Dividend Payment Date to and including the
               date as of which the calculation is made, based on a 360-day
               year of twelve 30-day months.

                    Accrued but unpaid dividends on the Series D Preferred
               will not bear interest. Holders of the Series D Preferred
               will not be entitled to any dividends in excess of full
               cumulative dividends as described above.


<PAGE>


                    (D) No dividends on shares of Series D Preferred shall
               be declared by the Board of Directors of the corporation or
               paid or set apart for payment by the corporation at such
               time as the terms and provisions of any agreement of the
               corporation, including any agreement relating to its
               indebtedness, prohibits such declaration, payment or setting
               apart for payment or provides that such declaration, payment
               or setting apart for payment would constitute a breach
               thereof or a default thereunder, or if such declaration or
               payment shall be restricted or prohibited by law.

                    (E) Except as provided in these Articles, the Series D
               Preferred shall not be entitled to participate in the
               earnings or assets of the corporation.

                    (F) In the event that the per share cash dividends
               declared on the common stock during any Dividend Period (the
               "Current Common Dividend") shall be greater or less than the
               per share cash dividends declared on the common stock during
               the immediately preceding Dividend Period (the "Prior Common
               Dividend"), then the dividend rate of the Series D Preferred
               (as it may have previously been adjusted pursuant to this
               subparagraph (F)) shall be automatically adjusted in the
               proportion that the Current Common Dividend bears to the
               Prior Common Dividend, such adjustment to be effective for
               the Dividend Period during which the Current Common Dividend
               is paid and all subsequent Dividend Periods until again
               adjusted in accordance with this paragraph; provided,
               however, that in no event shall the adjusted dividend rate
               of the Series D Preferred be less than 7.5% of the
               Liquidation Preference of the Series D Preferred per annum.
               No adjustment pursuant to this subparagraph (F) shall be
               made on account of any special common stock dividend or
               distribution declared for the purpose of assuring continued
               qualification of the corporation as a "real estate
               investment trust" under the Code.

               (4) Liquidation Rights.

                    (A) Upon the voluntary or involuntary dissolution,
               liquidation or winding up of the corporation, the holders of
               shares of the Series D Preferred then outstanding shall be
               entitled to receive and to be paid out of the assets of the
               corporation legally available for distribution to its
               shareholders, before any distribution shall be made to the
               holders of common stock or any other capital stock of the
               corporation ranking junior to the Series D Preferred upon
               liquidation, a liquidation preference of $25.00 per share
               (the "Liquidation Preference"), plus accrued and unpaid
               dividends thereon to the date of payment.

                    (B) After the payment to the holders of the shares of
               the Series D Preferred of the full Liquidation Preference
               provided for in this paragraph (4), the holders of the
               Series D Preferred as such shall have no right or claim to
               any of the remaining assets of the corporation.


<PAGE>


                    (C) If, upon any voluntary or involuntary dissolution,
               liquidation, or winding up of the corporation, the amounts
               payable with respect to the Liquidation Preference and any
               other shares of stock of the corporation ranking as to any
               such distribution on a parity with the shares of the Series
               D Preferred are not paid in full, the holders of the shares
               of the Series D Preferred and of such other shares will
               share ratably in any such distribution of assets of the
               corporation in proportion to the full respective liquidation
               preferences to which they are entitled.

                    (D) Neither the sale, lease, transfer or conveyance of
               all or substantially all the property or business of the
               corporation, nor the merger or consolidation of the
               corporation into or with any other corporation or the merger
               or consolidation of any other corporation into or with the
               corporation, shall be deemed to be a dissolution,
               liquidation or winding up, voluntary or involuntary, for the
               purposes of this paragraph (4).

               (5) Redemption.

                    (A) Right of Optional Redemption. The Series D
               Preferred is not redeemable prior to the fifth anniversary
               of the Issue Date. On and after the fifth anniversary of the
               Issue Date, the corporation may, at its option, redeem at
               any time all or, from time to time, part of the Series D
               Preferred at a price per share (the "Series D Redemption
               Price"), payable in cash, of $25.00, together with all
               accrued and unpaid dividends to and including the date fixed
               for redemption (the "Series D Redemption Date"), without
               interest; provided, however, that the corporation may not
               redeem any Series D Preferred pursuant to this paragraph (5)
               unless the Current Market Price of the common stock on each
               of the 20 consecutive Trading Days immediately preceding the
               Series D Redemption Date shall at least equal the then
               current Conversion Price, as defined in paragraph (7).
               "Current Market Price" of the common stock or any other
               class of capital stock or other security of the corporation
               or any other issuer for any day shall mean the last reported
               sale price, regular way, on such day or, if no sale takes
               place on such day, the average of the reported closing bid
               and asked prices on such day, regular way, in either case as
               reported on the New York Stock Exchange ("NYSE") or, if such
               security is not listed or admitted for trading on the NYSE,
               on the principal national securities exchange on which such
               security is listed or admitted for trading or, if not listed
               or admitted for trading on any national securities exchange,
               on the NASDAQ National Market or, if such security is not
               quoted on the NASDAQ National Market, the average of the
               closing bid and asked prices on such day in the
               over-the-counter market as reported by NASDAQ or, if bid and
               asked prices for such security on such day shall not have
               been reported through NASDAQ, the average of the bid and
               asked prices on such day as furnished by any NYSE member
               firm regularly making a market in such security and selected
               for such purpose by the Board of Directors. "Trading Day" in
               respect of any security shall mean any day on which such
               security is traded on the NYSE, or if 


<PAGE>


               such security is not listed or admitted for trading on the
               NYSE, on the principal national securities exchange on which
               such security is listed or admitted for trading, or if not
               listed or admitted for trading on any national securities
               exchange, on the NASDAQ National Market or, if such security
               is not quoted on the NASDAQ National Market, in the
               applicable securities market in which the security is
               traded.

                    In case of redemption of less than all shares of Series
               D Preferred at the time outstanding, the shares of Series D
               Preferred to be redeemed shall be selected pro rata from the
               holders of record of such shares in proportion to the number
               of shares of Series D Preferred held by such holders (as
               nearly as may be practicable without creating fractional
               shares) or by any other equitable method determined by the
               corporation.

                    (B) Procedures for Redemption.

                    (i) Notice of any redemption will be mailed by the
               corporation, postage prepaid, not less than 30 nor more than
               60 days prior to the Series D Redemption Date, addressed to
               the respective holders of record of the Series D Preferred
               to be redeemed at their respective addresses as they appear
               on the stock transfer records of the corporation. No failure
               to give such notice or any defect therein or in the mailing
               thereof shall affect the validity of the proceedings for the
               redemption of any Series D Preferred except as to the holder
               to whom the corporation has failed to give notice or except
               as to the holder to whom notice was defective. In addition
               to any information required by law, such notice shall state:
               (a) the Series D Redemption Date; (b) the Series D
               Redemption Price; (c) the number of shares of Series D
               Preferred to be redeemed; (d) the place or places where
               certificates for such shares are to be surrendered for
               payment of the Series D Redemption Price; and (e) that
               dividends on the shares to be redeemed will cease to
               accumulate on the Series D Redemption Date. If less than all
               the shares of Series D Preferred held by any holder are to
               be redeemed, the notice mailed to such holder shall also
               specify the number of shares of Series D Preferred held by
               such holder to be redeemed.

                    (ii) If notice of redemption of any shares of Series D
               Preferred has been mailed in accordance with section (i) of
               subparagraph (B) of this paragraph (5) above and provided
               that on or before the Series D Redemption Date specified in
               such notice all funds necessary for such redemption shall
               have been irrevocably set aside by the corporation, separate
               and apart from its other funds in trust for the benefit of
               any holders of the shares of Series D Preferred so called
               for redemption, so as to be, and to continue to be available
               therefor, then, from and after the Series D Redemption Date,
               dividends on such shares of Series D Preferred shall cease
               to accrue, and such shares shall no longer be deemed to be
               outstanding and shall not have the status of Series D
               Preferred and all rights of the holders thereof as
               shareholders of the corporation (except the right to receive


<PAGE>


               the Series D Redemption Price) shall terminate. Upon
               surrender, in accordance with said notice, of the
               certificates for any shares of Series D Preferred so
               redeemed (properly endorsed or assigned for transfer, if the
               corporation shall so require and the notice shall so state),
               such shares of Series D Preferred shall be redeemed by the
               corporation at the Series D Redemption Price. In case less
               than all the shares of Series D Preferred represented by any
               such certificate are redeemed, a new certificate or
               certificates shall be issued representing the unredeemed
               shares of Series D Preferred without cost to the holder
               thereof.

                    (iii) The deposit of funds with a bank or trust company
               for the purpose of redeeming Series D Preferred shall be
               irrevocable except that:

                         (a) the corporation shall be entitled to receive
                    from such bank or trust company the interest or other
                    earnings, if any, earned on any money so deposited in
                    trust, and the holders of any shares redeemed shall
                    have no claim to such interest or other earnings; and

                         (b) any balance of moneys so deposited by the
                    corporation and unclaimed by the holders of the Series
                    D Preferred entitled thereto at the expiration of two
                    years from the applicable Series D Redemption Date
                    shall be repaid, together with any interest or other
                    earnings earned thereon, to the corporation, and after
                    any such repayment, the holders of the shares entitled
                    to the funds so repaid to the corporation shall look
                    only to the corporation for payment without interest or
                    other earnings.

                    (C) Limitations on Redemption

                    (i) The Series D Redemption Price (other than the
               portion thereof consisting of accrued and unpaid dividends)
               shall be payable solely out of the sale proceeds of other
               capital stock of the corporation and from no other source.

                    (ii) Unless full cumulative dividends on all shares of
               Series D Preferred shall have been or contemporaneously are
               declared and paid or declared and a sum sufficient for the
               payment thereof set apart for payment for all past Dividend
               Periods and the then current Dividend Period, no Series D
               Preferred shall be redeemed (unless all outstanding shares
               of Series D Preferred are simultaneously redeemed) or
               purchased or otherwise acquired directly or indirectly by
               the corporation (except by exchange for Junior Stock);
               provided, however, that the foregoing shall not prevent the
               redemption of Series D Preferred pursuant to Article 4 or
               the purchase or acquisition of Series D Preferred pursuant
               to a purchase or exchange offer made on the same terms to
               holders of all outstanding shares of Series D Preferred.

                    (iii) The corporation shall not redeem in any period of
               12 consecutive months a number of shares of Series D
               Preferred having an aggregate Liquidation 


<PAGE>


               Preference of more than $100,000,000, provided that this
               restriction shall lapse and be of no further force or effect
               if in any such period any holder of record of such number of
               shares of Series D Preferred or shares of common stock
               issued on conversion of such number of shares of Series D
               Preferred shall transfer beneficial ownership of such number
               of shares of Series D Preferred or such common stock, or a
               combination of shares of Series D Preferred and such common
               stock representing such number of shares of Series D
               Preferred, except (a) in a distribution of such shares of
               Series D Preferred and/or shares of common stock to the
               security holders of such holder of record or (b) in a bona
               fide pledge to a bank or other financial institution to
               secure obligations for borrowed money, or as margin
               collateral, or upon foreclosure or private sale under such
               pledge.

                    (D) Rights to Dividends on Shares Called for
               Redemption. If the Series D Redemption Date is after a
               Dividend Record Date and before the related Dividend Payment
               Date, the dividend payable on such Dividend Payment Date
               shall be paid to the holder in whose name the shares of
               Series D Preferred to be redeemed are registered at the
               close of business on such Dividend Record Date
               notwithstanding the redemption thereof between such Dividend
               Record Date and the related Dividend Payment Date or the
               corporation's default in the payment of the dividend due.
               Except as provided in this paragraph (5), the corporation
               will make no payment or allowance for unpaid dividends,
               whether or not in arrears, on called Series D Preferred.

               (6) Voting Rights. Except as required by the Virginia Stock
               Corporation Act and except as otherwise provided in this
               paragraph (6), the holders of the Series D Preferred shall
               not be entitled to vote at any meeting of the shareholders
               for election of directors or for any other purpose or
               otherwise to participate in any action taken by the
               corporation or the shareholders thereof, or to receive
               notice of any meeting of shareholders.

                    (A) Whenever dividends on any shares of Series D
               Preferred shall be in arrears for any Dividend Period, the
               holders of such shares of Series D Preferred shall have all
               rights to notices and voting entitlements of holders of
               common stock under the Virginia Stock Corporation Act and
               these Articles, and the Series D preferred and the common
               stock shall be a single voting group, until all dividends
               accumulated on such shares of Series D Preferred for all
               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.

                    (B) So long as any shares of Series D Preferred remain
               outstanding, the corporation shall not, without the
               affirmative vote of the holders of at least a majority of
               the shares of the Series D Preferred outstanding at the
               time, (i) authorize or create, or increase the authorized or
               issued amount of, any class or series of capital stock
               ranking prior to the Series D Preferred with respect to
               payment of dividends or the distribution of assets upon
               liquidation, dissolution or 


<PAGE>


               winding up or reclassify any authorized capital stock of the
               corporation into any 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 these Articles,
               whether by merger, consolidation or otherwise, so as to
               materially and adversely affect any right, preference,
               privilege or voting power of the Series D Preferred or the
               holders thereof; provided, however, that any increase in the
               amount of the authorized preferred stock or the creation or
               issuance of any other series of preferred stock, or any
               increase in the amount of authorized shares of such series,
               in each case ranking on a parity with or junior to the
               Series D Preferred with respect to payment of dividends or
               the distribution of assets upon liquidation, dissolution or
               winding up, shall not be deemed to materially and adversely
               affect such rights, preferences, privileges or voting
               powers.

                    (C) 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 Series D Preferred shall have been
               redeemed or called for redemption upon proper notice and
               sufficient funds shall have been deposited in trust to
               effect such redemption.

               (7) Conversion of Series D Preferred.

                    (A) As used in this paragraph (7), the following terms
               shall have the indicated meanings:

                    "Adjustment Factor," for purposes of any determination
               provided for in this paragraph (7) requiring reference to
               the Adjustment Factor, shall equal the Conversion Price in
               effect on the determination date divided by $16.25.

                    "Conversion Price" shall mean the conversion price per
               share of common stock at which the Series D Preferred is
               convertible into common stock, as such Conversion Price may
               be adjusted pursuant to subparagraph (E) of this paragraph
               (7). The initial Conversion Price shall be $16.25.

                    "Conversion Rate" shall mean the rate at which the
               Series D Preferred is convertible into common stock, as such
               Conversion Rate may be adjusted pursuant to subparagraph (E)
               of this paragraph (7). The initial Conversion Rate shall be
               1.5385 shares of common stock for each share of Series D
               Preferred.

                    "Fair Market Value," in the case of any security or
               property not having a market value ascertainable by
               reference to any quotation medium or other objective source,
               shall mean the fair market value thereof as determined in
               good faith by the Board of Directors, which determination
               shall be final, conclusive and binding on all persons


<PAGE>


                    "Transfer Agent" shall mean ChaseMellon Shareholder
               Services, LLC, or such other agent or agents of the
               corporation as may be designated by the Board of Directors
               as the transfer agent for the Series D Preferred.

                    (B) Subject to and upon compliance with the provisions
               of this paragraph (7), a holder of shares of Series D
               Preferred shall have the right (the "Conversion Right"),at
               his option, at any time and from time to time, to convert
               such shares into the number of shares of fully paid and
               nonassessable common stock obtained by dividing the
               aggregate Liquidation Preference of such shares of Series D
               Preferred by the Conversion Price (as in effect at the time
               and on the date provided for in the last paragraph of
               subparagraph (C) of this paragraph (7)) by surrendering such
               shares to be converted, such surrender to be made in the
               manner provided in subparagraph (C) of this paragraph (7);
               provided, however, that the right to convert shares called
               for redemption pursuant to paragraph (5) shall terminate at
               the close of business on the Series D Redemption Date fixed
               for such redemption, unless the corporation shall default in
               making payment of any amounts payable upon such redemption
               under paragraph (5).

                    (C) In order to exercise the Conversion Right, the
               holder of each share of Series D Preferred to be converted
               shall surrender the certificate evidencing such share, duly
               endorsed or assigned to the corporation or in blank, at the
               office of the Transfer Agent, accompanied by written notice
               to the corporation that the holder thereof elects to convert
               such share of Series D Preferred. Unless the certificate or
               certificates for shares of common stock issuable on
               conversion are to be registered in the same name as the name
               in which such certificate for Series D Preferred is
               registered, each certificate surrendered for conversion
               shall be accompanied by instruments of transfer, in form
               satisfactory to the corporation, duly executed by the holder
               or such holder's duly authorized agent and an amount
               sufficient to pay any transfer or similar tax (or evidence
               reasonably satisfactory to the corporation demonstrating
               that such taxes have been paid).

                    Holders of Series D Preferred at the close of business
               on a Dividend Record Date shall be entitled to receive the
               dividend payable on the corresponding Dividend Payment Date
               notwithstanding the conversion thereof following such
               Dividend Record Date and prior to such Dividend Payment
               Date. However, shares of Series D Preferred surrendered for
               conversion during the period beginning with the close of
               business on any Dividend Record Date and ending with the
               opening of business on the corresponding Dividend Payment
               Date (except shares converted after the issuance of a notice
               of redemption specifying a Series D Redemption Date
               occurring within such period or coinciding with such
               Dividend Payment Date, such shares being entitled to such
               dividend on the Dividend Payment Date) must be accompanied
               by payment of an amount equal to the dividend payable on
               such shares on such Dividend Payment Date. A holder of
               shares of Series D Preferred on a Dividend Record Date who
               (or whose transferee) surrenders any such shares for
               conversion into common 


<PAGE>


               stock after the opening of business on the corresponding
               Dividend Payment Date will receive the dividend payable by
               the corporation on such Series D Preferred on such date, and
               the converting holder need not include payment of the amount
               of such dividend upon such surrender. The corporation shall
               make further payment or allowance for, and a converting
               holder shall be entitled to, unpaid dividends in arrears
               (excluding the then-current quarter) on converted shares and
               for dividends on the common stock issued upon such
               conversion.

                    As promptly as practicable after the surrender of
               certificates for Series D Preferred as aforesaid, the
               corporation shall issue and shall deliver at such office to
               such holder, or on his written order, a certificate or
               certificates for the number of full shares of common stock
               issuable upon the conversion of such Series D Preferred in
               accordance with the provisions of this paragraph (7), and
               any fractional interest in respect of common stock arising
               upon such conversion shall be settled as provided in
               subparagraph (D) of this paragraph (7). Each conversion
               shall be deemed to have been effected immediately prior to
               the close of business on the date on which the certificates
               for Series D Preferred shall have been surrendered and such
               notice (and if applicable, payment of an amount equal to the
               dividend payable on such shares) received by the corporation
               as aforesaid, and the person or persons in whose name or
               names any certificate or certificates for common stock shall
               be issuable upon such conversion shall be deemed to have
               become the holder or holders of record of the shares
               represented thereby at such time on such date, and such
               conversion shall be at the Conversion Price in effect at
               such time and on such date, unless the share transfer books
               of the corporation shall be closed on that date, in which
               event such person or persons shall be deemed to have become
               such holder or holders of record at the opening of business
               on the next succeeding day on which such share transfer
               books are open, but such conversion shall be at the
               Conversion Price in effect on the date on which such
               certificates for Series D Preferred have been surrendered
               and such notice received by the corporation.

                    (D) No fractional shares or scrip representing
               fractions of common stock shall be issued upon conversion of
               the Series D Preferred. In lieu of issuing a fractional
               interest in common stock that would otherwise be deliverable
               upon the conversion of a share of Series D Preferred, the
               corporation shall pay to the holder of such share an amount
               in cash based upon the Current Market Price of the common
               stock on the Trading Day immediately preceding the date of
               conversion. If more than one share of Series D Preferred
               shall be surrendered for conversion at one time by the same
               holder, the number of full shares of common stock issuable
               upon conversion thereof shall be computed on the basis of
               the aggregate number of shares of Series D Preferred so
               surrendered.

                    (E) The Conversion Rate and Conversion Price shall be
               adjusted from time to time as follows:


<PAGE>


                    (i) If the corporation shall after the Issue Date (a)
               declare and pay a dividend to holders of any class of
               capital stock of the corporation payable in common stock,
               (b) subdivide its outstanding common stock into a greater
               number of shares, (c) combine its outstanding common stock
               into a smaller number of shares or (d) reclassify its common
               stock, the Conversion Rate shall be adjusted so that the
               holder of any Series D Preferred thereafter surrendered for
               conversion shall be entitled to receive the number of shares
               of common stock that such holder would have owned or have
               been entitled to receive after the happening of any of the
               events described above had such shares been converted
               immediately prior to the record date in the case of a
               dividend or the effective date in the case of a subdivision,
               combination or reclassification. An adjustment made pursuant
               to this section (i) shall become effective immediately after
               the opening of business on the day next following the record
               date (except as provided in subparagraph (I) below) in the
               case of a dividend and shall become effective immediately
               after the opening of business on the day next following the
               effective date in the case of a subdivision, combination or
               reclassification. Such adjustment(s) shall be made
               successively whenever any of the events listed above shall
               occur.

                    (ii) If the corporation shall issue after the Issue
               Date rights, options or warrants to all holders of common
               stock entitling them to subscribe for or purchase common
               stock (or securities convertible into common stock) at a
               price per share (or having a conversion price per share)
               less than 98% of the Current Market Price of the common
               stock determined as of the record date for the determination
               of shareholders entitled to receive such rights, options or
               warrants, then the Conversion Price shall be adjusted to
               equal the price determined by multiplying (A) the Conversion
               Price in effect immediately prior to the close of business
               on such record date (B) a fraction, the numerator of which
               shall be the sum of (I) the number of shares of common stock
               outstanding on the close of business on such record date and
               (II) the number of shares of common stock that could be
               purchased at the Current Market Price on such record date
               with the aggregate proceeds to the corporation from the
               exercise of such rights, options or warrants (or the
               aggregate conversion price of the convertible securities so
               offered), and the denominator of which shall be the sum of
               (x) the number of shares of common stock outstanding on the
               close of business on such record date and (y) the number of
               shares of common stock issuable upon exercise in full of
               such rights, options or warrants (or into which the
               convertible securities so offered are convertible). Such
               adjustment shall become effective immediately after the
               opening of business on the day next following such record
               date (except as provided in subparagraph (I) below). In
               determining whether any rights, options or warrants entitle
               the holders of common stock to subscribe for or purchase
               common stock at less than 98% of the Current Market Price,
               there shall be taken into account any consideration received
               by the corporation upon issuance and upon exercise of such
               rights, options or warrants, the value of such
               consideration, if other than cash, to be determined by the
               Board of Directors, whose decision shall be final,
               conclusive, and binding on all persons. Any 


<PAGE>


               adjustment(s) made pursuant to this section (ii) shall be
               made successively whenever any of the events listed above
               shall occur.

                    (iii) If the corporation shall after the Issue Date
               distribute to all holders of its common stock any shares of
               capital stock of the corporation (other than common stock)
               or evidence of its indebtedness or assets (including
               securities or cash, but excluding cash dividends not
               exceeding in amount current or accumulated funds from
               operations at the date of declaration, determined on the
               basis of the corporation's most recent annual or quarterly
               report to shareholders at the time of the declaration of
               such dividends) or rights, options or warrants to subscribe
               for or purchase any of its securities (excluding rights,
               options or warrants referred to in section (ii) above) (any
               of the foregoing being hereinafter in this section (iii)
               called the "Securities"), then in each case the Conversion
               Price shall be adjusted so that it shall equal the price
               determined by multiplying (A) the Conversion Price in effect
               immediately prior to the close of business on the record
               date fixed for the determination of shareholders entitled to
               receive such distribution by (B) a fraction, the numerator
               of which shall be (I) the Current Market Price per share of
               common stock on such record date or, if applicable, the
               deemed record date described in the immediately following
               paragraph, less (II) the then Fair Market Value of the
               Securities or assets so distributed applicable to one share
               of common stock, and the denominator of which shall be the
               Current Market Price per share of common stock on such
               record date or, if applicable, the record date described in
               the immediately following paragraph. Such adjustment shall
               become effective immediately at the opening of business on
               the Business Day next following (except as provided in
               subparagraph (I)) such record date.

                    For purposes of this section (iii), distribution of a
               Security which is distributed not only to the holders of the
               common stock on the record date fixed for the determination
               of shareholders entitled to such distribution, but is also
               delivered with each share of common stock issued upon
               conversion of Series D Preferred after such record date,
               shall not require an adjustment of the Conversion Price
               pursuant to this section (iii); provided that on the date,
               if any, on which such Security ceases to be deliverable with
               common stock upon conversion of Series D Preferred (other
               than as a result of the expiration or termination of all
               such Securities), a distribution of such Securities shall be
               deemed to have occurred, and the Conversion Price shall be
               adjusted as provided in this section (iii) (and such date
               shall be deemed for purposes of this section (iii) to be the
               "record date fixed for the determination of shareholders
               entitled to receive such distribution" and the "record
               date").

                    Adjustment(s) made pursuant to this section (iii) shall
               be made successively whenever any of the events listed above
               shall occur.

                    (iv) If after the Issue Date (i) the corporation shall
               merge or consolidate with any other 


<PAGE>


               real estate investment trust, corporation or other business
               entity and shall not be the survivor in such transaction
               (without respect to the legal structure of the transaction),
               (ii) the corporation shall transfer or sell all or
               substantially all of its assets other than to an affiliate
               or subsidiary of the corporation or (iii) the corporation
               shall liquidate and dissolve, and the consideration
               allocable to each share of common stock in any such
               transaction shall not have a Fair Market Value of at least
               $15 times the Adjustment Factor, the Conversion Price in
               effect at the opening of business on the date on which such
               transaction is consummated or effective, if greater than $15
               times the Adjustment Factor, shall be adjusted effective at
               the opening of business on such date to equal $15 times the
               Adjustment Factor.

                    (v) If the Current Market Price of the common stock on
               at least 20 consecutive Trading Days during the period of 36
               consecutive months beginning on the second anniversary of
               the Issue Date is not at least $14 times the Adjustment
               Factor, and the Conversion Price in effect at the opening of
               business on the fifth anniversary of the Issue Date or the
               next succeeding Business Day, if such fifth anniversary is
               not a Business Day, is greater than $15.25 times the
               Adjustment Factor, the Conversion Price shall be adjusted
               effective at the opening of business on such fifth
               anniversary or the next following Business Day, if such
               fifth anniversary is not a Business Day, to equal $15.25
               times the Adjustment Factor.

                    (vi) No adjustment in the Conversion Price shall be
               required unless such adjustment would require a cumulative
               increase or decrease of at least 1% in such price; provided,
               however, that any adjustments that by reason of this section
               (vi) are not required to be made shall be carried forward
               and taken into account in any subsequent adjustment until
               made; and provided, further, that any adjustment shall be
               required and made in accordance with the provisions of this
               paragraph (7) (other than this section (vi)) not later than
               such time as may be required in order to preserve the
               tax-free nature of a dividend to the holders of common
               stock. Notwithstanding any other provisions of this
               paragraph (7), the corporation shall not be required to make
               any adjustment to the Conversion Price for the issuance of
               any common stock pursuant to any plan providing for the
               reinvestment of dividends or interest payable on securities
               of the corporation and the investment of additional optional
               amounts in common stock under such plan. All calculations
               under this paragraph (7) shall be made to the nearest cent
               (with $.005 being rounded upward) or to the nearest
               one-tenth of a share (with .05 of a share being rounded
               upward), as the case may be.

                    (F) If the corporation shall after the Issue Date be a
               party to any transaction (including without limitation a
               merger, consolidation, statutory share exchange, self tender
               offer for all or substantially all of the outstanding common
               stock, sale of all or substantially all of the corporation's
               assets, recapitalization or reclassification of capital
               stock, but excluding any transaction to which section (i) of
               subparagraph (E) of this paragraph (7) applies (each of the
               foregoing being 


<PAGE>


               referred to herein as a "Transaction"), in each case upon
               consummation of which common stock shall be converted into
               the right to receive shares, stock, securities or other
               property (including cash) or any combination thereof
               ("Transaction Consideration"), each share of Series D
               Preferred which is not itself converted into the right to
               receive Transaction Consideration in connection with such
               Transaction shall thereafter be convertible into the kind
               and amount of Transaction Consideration payable upon the
               consummation of such Transaction with respect to that number
               of shares of common stock into which one share of Series D
               Preferred was convertible immediately prior to such
               Transaction. The corporation shall not be a party to any
               Transaction unless the terms of such Transaction are
               consistent with this subparagraph (F) and enable the holder
               of each share of Series D Preferred that remains outstanding
               after consummation of such Transaction to convert such share
               at the Conversion Price in effect immediately prior to such
               Transaction into the Transaction Consideration payable with
               respect to the number of shares of common stock into which
               such share of Series D Preferred is then convertible. The
               provisions of this subparagraph (F) shall similarly apply to
               successive Transactions.

                    (G) If after the Issue Date:

                    (i) the corporation shall declare dividends on the
               common stock, excluding cash dividends not exceeding in
               amount current or accumulated funds from operations at the
               date of declaration, determined on the basis of the
               corporation's most recent annual or quarterly report to
               shareholders at the time of the declaration of such
               dividends; or

                    (ii) the corporation shall authorize the granting to
               the holders of the common stock of rights, options or
               warrants to subscribe for or purchase any shares of any
               class or any other rights, options or warrants; or

                    (iii) there shall be any Transaction for which approval
               of any shareholders of the corporation is required or self
               tender for all or substantially all of the outstanding
               common stock; or

                    (iv) there shall occur the voluntary or involuntary
               liquidation, dissolution or winding up of the corporation;

                    then the corporation shall cause to be filed with the
               Transfer Agent and shall cause to be mailed to the holders
               of the Series D Preferred at their addresses as shown on the
               share records of the corporation, as promptly as possible,
               but at least 15 days prior to the earliest applicable date
               hereinafter specified, a notice stating (A) the record date
               as of which the holders of common stock entitled to receive
               such dividend or grant of rights, options or warrants are to
               be determined, provided, however, that no such notification
               need be made in respect of a record date for a dividend or
               grant of rights, options or warrants unless the


<PAGE>


               corresponding adjustment in the Conversion Price would be an
               increase or decrease of at least 1%, or (B) the date on
               which such Transaction, self tender, liquidation,
               dissolution or winding up is expected to become effective,
               and the date as of which it is expected that holders of
               common stock of record shall be entitled to exchange their
               common stock for securities or other property, if any,
               deliverable upon such Transaction, self tender, liquidation,
               dissolution or winding up. Failure to give such notice or
               any defect therein shall not affect the legality or validity
               of the proceedings described in this paragraph (7).

                    (H) Whenever the Conversion Price is adjusted as herein
               provided, the corporation shall promptly file with the
               Transfer Agent a certificate of its chief financial or chief
               accounting officer setting forth the Conversion Price after
               such adjustment and setting forth a brief statement of the
               facts requiring such adjustment, which certificate shall be
               conclusive evidence of the correctness of such adjustment
               absent manifest error. Promptly after delivery of such
               certificate, the corporation shall prepare a notice of such
               adjustment of the Conversion Price setting forth the
               adjusted Conversion Price and the effective date on which
               such adjustment becomes effective and shall mail such notice
               of such adjustment of the Conversion Price to the holder of
               each share of Series D Preferred at such holder's last
               address of record.

                    (I) In any case in which subparagraph (E) of this
               paragraph (7) provides that an adjustment shall become
               effective on the date next following the record date for an
               event, the corporation may defer until the occurrence of
               such event (i) issuing to the holder of any Series D
               Preferred converted after such record date and before the
               occurrence of such event the additional common stock
               issuable upon such conversion by reason of the adjustment
               required by such event over and above the common stock
               issuable upon such conversion before giving effect to such
               adjustment and (ii) fractionalizing any share of common
               stock into which Series D Preferred is convertible and/or
               paying to such holder cash in lieu of such fractional
               interest pursuant to subparagraph (D) of this paragraph (7).

                    (J) There shall be no adjustment of the Conversion
               Price in case of the issuance of any shares of capital stock
               of the corporation in a reorganization, acquisition or other
               similar transaction except as specifically set forth in this
               paragraph (7).

                    (K) The corporation will at all times reserve and keep
               available, free from preemptive rights, out of its
               authorized but unissued common stock, for the purpose of
               effecting conversion of the Series D Preferred, the full
               number of shares of common stock deliverable upon the
               conversion of all outstanding Series D Preferred not
               theretofore converted. For purposes of this subparagraph
               (K), the number of shares of common stock deliverable upon
               the conversion of all outstanding shares of Series D
               Preferred shall be computed as if at the time of computation
               all such outstanding shares were held by a single holder.


<PAGE>


                    (L) The corporation will pay any and all documentary
               stamp or similar issue or transfer taxes payable in respect
               of the issue or delivery of common stock or other securities
               or property on conversion of the Series D Preferred pursuant
               hereto; provided, however, that the corporation shall not be
               required to pay any tax that may be payable in respect of
               any transfer involved in the issue or delivery of common
               stock or other securities or property in a name other than
               that of the holder of the Series D Preferred to be
               converted, and no such issue or delivery shall be made
               unless and until the person requesting such issue or
               delivery has paid to the corporation the amount of any such
               tax or has established, to the reasonable satisfaction of
               the corporation, that such tax has been paid.

                    In addition to the foregoing adjustments, the
               corporation shall be entitled to make such reductions in the
               Conversion Price, in addition to those required herein, as
               it in its discretion considers to be advisable in order that
               any share dividends, subdivisions of shares,
               reclassification or combination of shares, dividend of
               rights, options, warrants to purchase shares or securities,
               or a dividend of other assets (other than cash dividends)
               will not be taxable or, if that is not possible, to diminish
               any income taxes that are otherwise payable because of such
               event.

                    (M) Definitions. Unless the context otherwise clearly
               indicates, terms defined in any subdivision of this
               paragraph (7) shall have the same meanings wherever used in
               this paragraph (7).

Inc., a Virginia corporation (the "Company") and United Dominion Realty,
L.P., a Virginia limited partnership (the "Company Operating Partnership").

                                  RECITALS

          WHEREAS, the Transferors are the legal and beneficial owners of

          WHEREAS, as an inducement to the Company to enter into an
Agreement and Plan of Merger (the "Merger Agreement") with American
Apartment Communities II, Inc., a Maryland corporation ("AAC"), whereby AAC
will merge with and into the Company (the "Merger") and thus benefit the
Contributors, the Contributors have agreed to contribute their respective

Interests from the Contributors, as provided herein;

          WHEREAS, in connection with the Merger, the Sellers have agreed

cash, and the Company desires to acquire the AACLP Partnership Interests
from the Sellers, as provided herein;

          WHEREAS, together with AAC, the Transferors own all of the

          WHEREAS, the parties intend to provide certain protections for

          NOW, THEREFORE, in consideration of the foregoing, the mutual
agreements contained herein and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged by the parties
hereto, the parties hereto do hereby agree as follows:


<PAGE>

     1. Contribution and Sale. (a) Pursuant to the terms hereof, the
Contributors hereby agree to contribute AACLP Partnership Interests to the
Company Operating Partnership free and clear of any and all restrictions on
transfer (other than restrictions under the Securities Act and state
securities laws), taxes, mortgages, liens, encumbrances, charges, pledges,
impositions, security interests, options, warrants, purchase rights, rights
of first refusal, contracts, commitments, equities, claims and demands
("Liens"), and the Company Operating Partnership hereby agrees to accept
such AACLP Partnership Interests from the Contributors, in exchange for an
aggregate amount of units of limited partnership interest in the Company
Operating Partnership (the "UDR Units") as set forth on Exhibit A (the
"Exchange Equity Consideration"). Any Contributor who receives UDR Units in
such exchange (a "UDR Unit Holder") shall, upon the issuance of such UDR
Units, be admitted as a limited partner of the Company Operating
Partnership and shall sign the Third Amended and Restated Agreement of
Limited Partnership of the Company Operating Partnership, in substantially
the form attached hereto as Exhibit D (the "Partnership Agreement").

          (b) Pursuant to the terms hereof, the Sellers hereby agree to

all Liens, and the Company hereby agrees to purchase such AACLP Partnership
Interests from the Sellers, for an aggregate amount of cash as set forth on
Exhibit B (the "Exchange Cash Consideration," and, together with the
Exchange Equity Consideration, the "Exchange Consideration"), subject to
adjustment as provided in Section 1(c) below.

          (c) The Exchange Consideration shall be adjusted in accordance
with the provisions of Section 2.2 of the Merger Agreement. The allocation
of the Exchange Consideration among the Transferors shall be determined by
AACLP and AACLP shall provide such allocations to the Company on or before

Operating Partnership, L.P. and AAC Management, L.L.C.) no longer own at
least 50% of the aggregate UDR Units issued to such persons pursuant to
this Agreement or (b) Mr. Klingbeil reaches age 70, Mr. Klingbeil shall be
nominated for election to the Board of Directors of the Company. For the
purpose of the preceding sentence, any common stock of UDR issued upon
redemption of UDR Units by Mr. Klingbeil or his affiliates (and held by
such person on the date of determination) shall be counted toward the
number of UDR Units held by such persons. For so long as Mr. Klingbeil
continues to be nominated pursuant to this Section 2, he shall be deemed
for purposes of Section 5.8 of the Merger Agreement a nominee of the Holder
referred to therein.

     3. Contributors' and Sellers' Representations and Warranties. Each
Transferor, severally and not jointly, hereby represents and warrants to
the Company and the Company Operating Partnership, as of the date hereof

<PAGE>

     other applicable non-recognition Code provision, in which no gain or
     loss is recognized for federal income tax purposes (a "Non-Recognition
     Transaction") and (ii) none of the AAC Properties identified in
     Schedule 5C (or any property acquired in a like-kind exchange under
     Section 1031 or 1033 of the Code in replacement thereof) ("Schedule 5C
     Properties") will be sold, transferred or otherwise disposed of other
     than in a Non-Recognition Transaction.

     (c)  AAC Property Refinancings.

          (i) Except as otherwise provided in Sections 5(c)(ii) and
          5(c)(iii), during the period ending on the twelfth anniversary of
          the Closing Date with respect to the Schedule 5B Properties
          (excluding Grandview Terrace, Sunset Village, Tivoli of Columbus,
          and Mountain View), and indefinitely with respect to the Schedule
          5C Properties ("Refinancing Period") (A) the existing mortgage
          indebtedness encumbering such AAC Properties ("Existing
          Indebtedness") or any replacement indebtedness assumed or taken
          subject to in a Section 1031 Transaction ("Replacement
          Indebtedness") will not be prepaid, (B) any Replacement

          replacement property and (C) the Existing Indebtedness or
          Replacement Indebtedness will not be converted from nonrecourse
          indebtedness to recourse indebtedness, except that (I) regularly
          scheduled periodic principal payments on Existing Indebtedness or
          Replacement Indebtedness may be made and (II) Existing
          Indebtedness or Replacement Indebtedness may be refinanced
          provided the refinancing indebtedness ("Refinancing
          Indebtedness") is (X) nonrecourse; (Y) does not require principal
          repayments during such period which are greater than the payments
          required on Existing Indebtedness during such period; and (Z) is
          secured solely by the AAC Property or Properties which secure the
          Existing Indebtedness or the Replacement Indebtedness which is
          being refinanced. In addition, any Refinancing Indebtedness may
          be refinanced provided any indebtedness which refinances
          Refinancing Indebtedness shall satisfy all the requirements of
          this Section 5(c)(i). The determination of whether indebtedness
          is recourse or nonrecourse shall be determined under Section 752
          of the Code.

          (ii) If, during the Refinancing Period, the Company decides to
          refinance or prepay the Existing Indebtedness or the Replacement
          Indebtedness in a manner that is not in compliance with Section
          5(c)(i), the Company will give written notice ("Refinancing
          Notice") to each Tax Partner at least 60 days prior to such
          refinancing or prepayment. Such Refinancing Notice must be given
          with respect to each proposed refinancing or prepayment
          transaction on a property-by-property basis. The Refinancing
          Notice will describe which Existing Indebtedness or Replacement
          Indebtedness is scheduled to be refinanced or prepaid, how much
          of such Existing Indebtedness or Replacement Indebtedness is
          scheduled to be refinanced or prepaid, and approximately when the
          refinancing or prepayment is scheduled to occur. Upon receipt of
          the Refinancing Notice, each 


<PAGE>

          Tax Partner shall have the option (A) to guarantee debt of the
          Company Operating Partnership (or enter into a reimbursement
          agreement with the Company with respect to debt of the Company
          Operating Partnership) in an amount that prevents such Tax
          Partner from recognizing income or gain for federal income tax
          purposes as a result of such refinancing or prepayment and/or (B)
          to exercise immediately its Redemption Rights for the Cash
          Amount, instead of the REIT Shares Amount (as those terms are
          defined in the Partnership Agreement), with respect to a number
          of UDR Units necessary to pay the federal and state income tax
          liability associated with the income or gain that is recognized
          as a result of such refinancing or prepayment. If such Tax
          Partner elects to guarantee debt as described in this Section
          5(c)(ii), the Company, the Company Operating Partnership and each
          such Tax Partner agree to negotiate in good faith a guaranty
          agreement or reimbursement agreement that is satisfactory to all
          parties, provided, however, that the Company shall be required to
          ensure that (i) such guaranty covers only the last dollars of
          liability with respect to such debt ("bottom guarantee") and (ii)
          there is a sufficient level of debt such that the bottom
          guarantee will put such Tax Partner in the same position for
          federal income tax purposes that it would have been in if the
          refinancing or prepayment were not effected. If (A) the Company
          does not receive written notice from a Tax Partner of its
          election to guarantee debt or to exercise its Redemption Rights
          as described in this Section 5(c)(ii) within 30 days after such
          Tax Partner's receipt of the Refinancing Notice or (B) a Tax
          Partner elects to exercise its Redemption Rights as described in
          this Section 5(c)(ii), the Company's and the Company Operating
          Partnership's obligations under Section 5(c)(i) with respect to
          the Existing Indebtedness or the Replacement Indebtedness that is
          scheduled to be refinanced or prepayment shall terminate;
          provided, however, that under no circumstances may a Tax
          Partner's action or inaction with respect to a Refinancing Notice
          be deemed to be a waiver of, or consent with respect to, any
          future Refinancing Notice relating to any future proposed
          refinancing or prepayment transaction. Furthermore, a new
          Refinancing Notice must be given with respect to each proposed
          refinancing or prepayment transaction on each property
          notwithstanding the fact that a prior refinancing or prepayment
          transaction had taken place with respect to any indebtedness (or
          portion of any indebtedness) secured by that property.

          (iii) With respect to the Grandview Terrace, Sunset Village,
          Tivoli of Columbus, and Mountain View AAC Properties, each Tax
          Partner shall have the option on the Closing Date (A) to
          guarantee debt of the Company Operating Partnership (or enter
          into a reimbursement agreement with the Company with respect to
          debt of the Company Operating Partnership) in an amount that
          prevents any Tax Partner from recognizing income or gain for
          federal income tax purposes as a result of the repayment of the
          mortgage indebtedness encumbering such properties and/or (B) to
          exercise immediately its Redemption Rights for the Cash Amount,
          instead of the REIT Shares Amount (as those terms are defined in
          the Partnership Agreement), with respect to a number of UDR Units
          necessary to pay 


<PAGE>

          the federal and state income tax liability associated with the
          income or gain that is recognized as a result of such repayment.
          If a Tax Partner elects to guarantee debt as described in this
          Section 5(c)(iii), the Company, the Company Operating Partnership
          and such Tax Partner agree to negotiate in good faith a guaranty
          agreement or reimbursement agreement that is satisfactory to all
          parties, provided, however, that the Company shall be required to
          ensure that (i) such guaranty is a the bottom guarantee and (ii)
          there is a sufficient level of debt such that the bottom
          guarantee of which will put such Tax Partner in the same position
          for federal income tax purposes that it would have been in if the
          refinancing or prepayment were not effected.

          (iv) Notwithstanding the foregoing, at any time in their sole
          discretion, the partners or interest holders of any Tax Partner
          may replace a reimbursement agreement with the Company with a
          direct guaranty on substantially the same terms as such
          reimbursement agreement.

          (v) Notwithstanding anything to the contrary in this Agreement,
          any Tax Partner may, in its sole discretion, at any time or from
          time to time, and the Company shall provide such Tax Partner with
          the opportunity to bottom guarantee debt of the Company Operating
          Partnership (or enter into a reimbursement agreement with the
          Company with respect to debt of the Company Operating
          Partnership) in an amount that prevents such Tax Partner from
          recognizing income or gain for federal income tax purposes.

          (vi) Notwithstanding anything to the contrary in this Agreement,
          the aggregate amount of indebtedness that the Company Operating
          Partnership shall be required to make available for the Tax
          Partners to bottom guarantee shall not exceed $200,000,000.

     (d) Approval of Fundamental Transactions. Except pursuant to the prior
     written consent of the holders of at least 66.66% of the
     then-outstanding UDR Units issued to the Contributors pursuant to this
     Agreement, neither the Company nor the Company Operating Partnership
     may merge, consolidate or otherwise combine with or into any other
     person, effect any reclassification, any recapitalization or change
     its outstanding equity interests (other than a change in par value, or
     from par value to no par value, or as a result of a subdivision or
     combination of REIT Shares), or sell all or substantially all of its
     assets (a "Fundamental Transaction") unless: (i) under the terms of
     the Fundamental Transaction, the UDR Unit Holders will not recognize
     any income or gain for Federal income tax purposes, either directly or
     through allocation of such income or gain from the Company Operating
     Partnership or any surviving entity; (ii) the UDR Unit Holders own a
     percentage interest of the Company Operating Partnership or another
     limited partnership or limited liability company that is the survivor
     of the Fundamental Transaction with the Company Operating Partnership
     (in each case, the "Surviving Partnership") based on the relative fair
     market value of the net assets of the Company Operating Partnership
     and the other net assets of the Surviving Partnership immediately


<PAGE>

     prior to the consummation of such Fundamental Transaction; and (iii)
     the rights, preferences and privileges of the UDR Unit Holders in the
     Surviving Partnership (including with respect to registration rights)
     are at least as favorable as those in effect immediately prior to the
     consummation of such Fundamental Transaction and as those applicable
     to any other limited partners or non-managing members of the Surviving
     Partnership and at least include the right to redeem their interests
     in the Surviving Partnership for the Maximum Transaction Consideration
     or an amount of cash equal to at least the value of the Maximum
     Transaction Consideration. "Maximum Transaction Consideration" shall
     mean an amount of cash, securities, or other property (or a
     partnership interest or other security readily convertible into such
     cash, securities, or other property) no less than the product of the
     REIT Shares Amount (as defined in the Partnership Agreement) and the
     greatest amount of cash, securities or other property (expressed as an
     amount per REIT Share (as defined in the Partnership Agreement)) paid
     in the Fundamental Transaction to the holder of one REIT Share in
     consideration for one REIT Share; provided, that if, in connection
     with the Fundamental Transaction, a purchase, tender or exchange offer
     ("Offer") shall have been made to and accepted by the holders of more
     than 50 percent of the outstanding REIT Shares, "Maximum Transaction
     Consideration" shall mean no less than the greatest amount of cash,
     securities or other property they would have received had they (Y)
     exercised their Redemption Right and (Z) sold, tendered or exchanged
     pursuant to the Offer the REIT Shares received upon exercise of the
     Redemption Right immediately prior to the expiration of the Offer.


The covenants of the Company and the Company Operating Partnership in this
Section 5 shall survive consummation of the transactions contemplated by
this Agreement and the Merger Agreement, any future transaction to which
the Company or the Company Operating Partnership is a party, including
without limitation, any Fundamental Transaction and any future transaction
of the kind referred to in the definition of "Change of Control" in Article

                                 ARTICLE II

                       REPRESENTATIONS AND WARRANTIES

          In order to assure the Company's compliance with applicable

Rule 501(a) of the Securities Act.

               (b) Such Holder is aware that the Securities have not been
registered under the Securities Act.

evaluated the information concerning the Company and the Company
Operating Partnership provided to such Holder by the Company, through
the management of AAC, in connection with the Merger and the Exchange,

answers from, the Company and its authorized representatives
concerning the terms and conditions of the Merger and the Exchange and

state a material fact necessary to make such information not
misleading in light of the circumstances.

                             ARTICLE III

                           LOCK-UP AGREEMENT

          Section 3.10

               (a) (i) The Preferred Holder agrees that until the
          second anniversary of the date of original issue of the
          Securities (the "Lock-up Period"), except as otherwise
          provided in this Agreement, the Preferred Holder will not
          offer, pledge, sell, contract to sell, grant any options for
          the sale of, seek the redemption or exchange of, transfer,
          distribute or otherwise dispose of, directly or indirectly
          (collectively "Dispose Of"), any of the Preferred Shares or
          Conversion Shares into which Preferred Shares have been
          converted.

                    (ii) Following the second anniversary of the date of
          original issuance of the Preferred Shares and during any 12
          month period thereafter, except as otherwise provided in
          this Agreement, the Preferred Holder shall be entitled to
          Dispose Of Preferred Shares, Conversion Shares or a
          combination of Preferred Shares and Conversion Shares
          representing up to the greater of (i) 50% of the original
          number of 


<PAGE>


          Preferred Shares, or their equivalent in Conversion Shares,
          or a combination of Preferred Shares and Conversion Shares
          representing up to 50% of the original number of Preferred
          Shares or (ii) the number of Conversion Shares or equivalent
          number of Preferred Shares, or a combination thereof,
          equaling the number of shares of Common Stock the total
          closing sale price of which on the NYSE on the day before
          the day on which the Preferred Holder seeks to Dispose Of
          such Securities is not more than 5% of Average Market
          Capitalization on such date. For purposes of this Section
          3.1(a)(ii) and Section 3.1(c), a number of Preferred Shares
          shall be deemed to be equivalent to the number of Conversion
          Shares into which it is convertible at the Conversion Price
          provided in the Company's Articles of Incorporation on the
          determination date, and a number of Conversion Shares shall
          be deemed to be equivalent to the number of Preferred Shares
          that, if converted at such Conversion Price, would equal
          such number of Conversion Shares.

                    (iii) The restrictions in Sections 3.1(a)(i) and
          3.1(a)(ii) shall terminate upon the occurrence of any
          Standstill Termination Event. The restrictions in Section
          3.1(a)(i) shall terminate upon any breach by the Company of
          its obligations under Article IV.

               (b) (i) Each UDR Unit Holder agrees that during the
          Lock-up Period, except as otherwise provided in this
          Agreement, such UDR Unit Holder will not redeem any of the
          UDR Units.

                    (ii) After the first anniversary, and prior to the
          second anniversary, of the date of original issue of the
          Securities, the UDR Unit Holders may collectively redeem in
          accordance with the Partnership Agreement UDR Units having
          an aggregate value not exceeding $15,000,000. The ability of
          the UDR Unit Holders to redeem up to an aggregate of
          $15,000,000 pursuant to the preceding sentence shall be
          allocated among such UDR Unit Holders pro-rata, based upon
          the number of UDR Units issued to each UDR Unit Holder
          pursuant to the Exchange Agreement. For purposes of this
          Section 3.1(b)(ii), the value of the UDR Units shall be
          assumed to be equal to the Cash Amount (as defined in the
          Partnership Agreement) that the Company Operating
          Partnership would be obligated to pay to the UDR Unit
          Holders upon redemption of such UDR Units pursuant to
          Article VIII of the Partnership Agreement.

                    (iii) The restrictions in Sections 3.1(b)(i) and
          3.1(b)(ii) shall terminate upon the occurrence of any
          Standstill Termination Event described in Section
          5.2(b)(ii), (iii), (iv) or (v). The restrictions in Section
          3.1(b)(i) shall terminate upon any breach by the Company of
          its obligations under Article IV. Upon any such termination
          pursuant to this Section 3.1(b)(iii), such UDR Unit Holders
          may redeem any or all UDR Units thereafter if the UDR Units
          are then redeemable under the terms of the Partnership
          Agreement. Such termination shall not affect any provision
          of the Partnership Agreement restricting or otherwise
          relating to redemption of UDR Units.


<PAGE>


          (c) The Preferred Holder may distribute any of its Preferred
Shares and Conversion Shares to its security holders (any such
security holder, a "Permitted Preferred Share Transferee") if before
such distribution it shall deliver to the Company:

               (i) an opinion of counsel reasonably acceptable to the
          Company that such distribution will not constitute or result
          in a violation of the registration requirements of the
          Securities Act and state "blue sky" laws,

               (ii) agreements substantially identical in form and
          substance to this Agreement executed by each Permitted
          Preferred Share Transferee who will together with the
          Controlled Affiliates of such Permitted Preferred Share
          Transferee Beneficially Own as a result of such distribution
          more than 40% of the original number of Preferred Shares, or
          their equivalent in Conversion Shares, or a combination of
          Preferred Shares and Conversion Shares representing more
          than 40% of the original number of Preferred Shares.

Upon any such distribution, each Permitted Preferred Share Transferee
shall continue to be bound by Section 3.1(a)(i), shall be entitled to
all of the rights of, subject to all limitations and obligations
applicable to, the Preferred Holder under Article IV, and, except as
contemplated by Section 3.1(c)(ii), shall not be bound by Section 5.1
but shall be entitled to the benefits of Section 5.2.

               (d) The Company and the Company Operating Partnership
          will consider any proposal by any UDR Unit Holder to
          distribute any of its UDR Units and Conversion Shares to its
          security holders and, in the case of any such security
          holder who is an individual, such individual's Family
          Members, in light of factors relevant at the time of such
          proposal, including but not limited to whether such proposed
          distribution is likely to cause the Company Operating
          Partnership to be a "publicly traded partnership" as defined
          in Section 7704 of the Internal Revenue Code of 1986, as
          amended, and whether all participants in such proposed
          distribution are "accredited investors" as defined in Rule
          501(a) under the Securities Act. This Section 3.1(d) shall
          not be construed to require consent to any such proposal,
          and any such distribution, if consented to, shall be subject
          to all applicable provisions of the Partnership Agreement.

               (e) Notwithstanding Sections 3.1(a)(i) and 3.1(a)(ii),
          the Preferred Holder may from time to time, in a transaction
          or transactions entered into bona fide and not for the
          purpose of evading any provision of this Agreement, pledge
          all or any of the Preferred Shares (i) to a bank or other
          financial institution to secure obligations for borrowed
          money or (ii) as margin collateral. Upon foreclosure or
          private sale under any such pledge, neither the pledgee nor
          any transferee of the pledgee shall be bound by or entitled
          to any benefits or rights under any provision of this
          Agreement (except this Section 3.1(e) and Article IV). Prior
          to any such pledge, foreclosure or private sale, the Company
          shall receive an opinion of counsel reasonably acceptable to
          the Company to the effect that the applicable transaction
          will not constitute or


<PAGE>


          result in a violation of the registration requirements of the
          Securities Act and state "blue sky" laws.

               (f) Notwithstanding Sections 3.1(b)(i) and 3.1(b)(ii),
          any UDR Unit Holder may from time to time, in a transaction
          or transactions entered into bona fide and not for the
          purpose of evading any provision of this Agreement, pledge
          all or any of its UDR Units (i) to a bank or other financial
          institution to secure obligations for borrowed money or (ii)
          as margin collateral, provided, however, that the pledgee
          shall agree that upon any foreclosure or private sale under
          such pledge, all such UDR Units will be sold to not more
          than one purchaser. Upon any such foreclosure or private
          sale, neither the pledgee nor any transferee of the pledgee
          shall be bound by or entitled to any benefits or rights
          under any provision of this Agreement (except this Section
          3.1(f) and Article IV). Prior to any such pledge,
          foreclosure or private sale, the Company shall receive an
          opinion of counsel reasonably acceptable to the Company to
          the effect that the applicable transaction will not
          constitute or result in a violation of the registration
          requirements of the Securities Act and state "blue sky"
          laws. The provisions of Article IX of the Partnership
          Agreement shall apply to any such foreclosure or private
          sale as though the pledgee were the transferor Limited
          Partner, as defined in the Partnership Agreement, referred
          to therein and the purchaser on foreclosure or in the
          private sale were the assignee of such transferor Limited
          Partner.

                              ARTICLE IV

                          REGISTRATION RIGHTS

          Section 4.10...Registration.

          (a) Filing of Registration Statement. Subject to the
conditions set forth in this Agreement, the Company shall file a
Registration Statement:

          (i) with respect to Conversion Shares issuable upon exchange
          for UDR Units redeemable in accordance with Section
          3.1(b)(ii), not later than 14 days after the first
          anniversary of the date of original issue of the Securities,

          (ii) with respect to the Conversion Shares issuable upon
          conversion of the Preferred Shares, not later than 14 days
          after the earlier of (A) the first anniversary of the date
          of original issue of the Securities or (B) the occurrence of
          a Standstill Termination Event,

          (iii) with respect to the Conversion Shares issuable upon
          exchange for UDR Units other than those, if any, with
          respect to which a Registration Statement has been filed
          (and continues to be effective) pursuant to (i) above, not
          later than 14 days after the earlier of (A) expiration of
          the Lock-up Period or (B) termination of the restrictions in
          Section 3.1(b)(i) and 3.1(b)(ii),


<PAGE>


          (iv) with respect to Conversion Shares issuable on
          conversion of Preferred Shares pledged pursuant to
          Section3.1(e) other than such Conversion Shares, if any,
          with respect to which a Registration Statement has been
          filed (and continues to be effective) pursuant to (ii)
          above, promptly after receipt of notice from the pledgee of
          a foreclosure on or private sale of such Conversion Shares
          pursuant to such pledge, and (v) with respect to Conversion
          Shares issuable upon exchange of UDR Units pledged pursuant
          to Section3.1(f) other than such Conversion Shares, if any,
          with respect to which a Registration Statement has been
          filed (and continues to be effective) pursuant to (i) above,
          promptly after receipt of notice from the pledgee of a
          foreclosure on or private sale of such Conversion Shares
          pursuant to such pledge,

and shall cause such Registration Statement to be declared effective
by the SEC as soon as practicable but in no event later than 60 days
after filing. The Company agrees to use reasonable efforts to keep the
Registration Statement, after its date of effectiveness, continuously
effective in accordance with Section 4.1(c). The Company will include
in any Registration Statement relating to Conversion Shares issued to
a Transaction Party Affiliate the disclosures necessary to enable such
Transaction Party Affiliate to reoffer such Conversion Shares in
compliance with the Securities Act by delivery of the Prospectus
included therein, unless such use of such Registration Statement is
prohibited by any rule or regulation (including staff interpretation)
of the SEC, in which case the Company shall file simultaneously with
such Registration Statement a separate Registration Statement relating
to the reoffer of such Conversion Shares by such Transaction Party
Affiliate (a "Reoffer Registration Statement"), shall cause such
Reoffer Registration Statement to be declared effective by the SEC as
soon as practicable but in no event later than 60 days after filing,
and shall use reasonable efforts to keep such Reoffer Registration
Statement, after its date of effectiveness, continuously effective in
accordance with Section 4.1(c). The term "Reoffer Registration
Statement" shall include any Registration Statement applicable to both
the issuance of Conversion Shares and the reoffer of such Conversion
Shares by a Transaction Party Affiliate. In the event that under any
rule or regulation (including staff interpretation) of the SEC, a
Registration Statement filed pursuant to this Section 4.1(a) may not
be used to register Conversion Shares for purposes of distribution of
such Conversion Shares to any Holder and/or any First-Tier Transferee,
such Registration Statement shall relate to the reoffer of such
Conversion Shares by such Holder and/or such First-Tier Transferee,
such Registration Statement shall be deemed a Reoffer Registration
Statement for purposes of this Article IV, and the Holder and /or each
such First-Tier Transferee shall be deemed a Transaction Party
Affiliate for such purposes. The Company shall not be deemed to be in
breach of this Section 4.1(a) if the SEC refuses to accept or make
effective a Reoffer Registration Statement filed pursuant to (ii)
above because the Conversion Shares to which such Registration
Statement relates are subject to the restrictions in Section
3.1(a)(1), provided the Company refiles such Reoffer Registration
Statement promptly after such restrictions terminate and causes such


<PAGE>


Reoffer Registration Statement to be declared effective by the SEC as
soon as practicable but in no event later than 60 days after refiling.

          (b) Notification and Distribution of Materials. The Company
shall promptly notify each Transaction Party Affiliate of the
effectiveness of any Reoffer Registration Statement applicable to
Conversion Shares issued to such Transaction Party Affiliate or
pledgee and shall furnish to such Transaction Party Affiliate such
number of copies of such Reoffer Registration Statement (including any
amendments, supplements and exhibits), the Prospectus contained
therein (including each preliminary prospectus and all related
amendments and supplements) and any documents incorporated by
reference in the Reoffer Registration Statement or such other
documents as such Transaction Party Affiliate may reasonably request
in order to facilitate the reoffer and sale of such Conversion Shares
in the manner described in such Reoffer Registration Statement.

          (c) Amendments and Supplements. The Company shall prepare
and file with the SEC from time to time such amendments and
supplements to each Registration Statement and Prospectus used in
connection therewith as may be necessary to keep such Registration
Statement effective and, in the case of a Reoffer Registration
Statement, to comply with the provisions of the Securities Act with
respect to the disposition of the Conversion Shares offered by the
Transaction Party Affiliates for which such Reoffer Registration
Statement is filed, until all Conversion Shares have been issued upon
conversion of Preferred Shares and exchange of UDR Units and, in the
case of such Reoffer Registration Statement, until the earlier of (a)
the date on which such Transaction Party Affiliates no longer hold any
Conversion Shares or (b) in the case of Transaction Party Affiliates
who are AAC Affiliates, the date on which no such Transaction Party
Affiliates are deemed to be engaged in a distribution by reason of
paragraph (d)(3) of Rule 145, or, in the case of Transaction Party
Affiliates who are UDR Affiliates and Persons who are deemed to be
Transaction Party Affiliates pursuant to the last sentence of Section
4.1(a), the Conversion Shares held by such Transaction Party
Affiliates or deemed Transaction Party Affiliates become eligible for
sale under paragraph (k) of Rule 144 (the "Reoffer Registration
Expiration Date"). Upon 20 business days' notice from a Transaction
Party Affiliate, the Company shall file any supplement or
post-effective amendment to a Reoffer Registration Statement with
respect to such Transaction Party Affiliate's plan of distribution,
such Transaction Party Affiliate's ownership interests in securities
of the Company, or other matters required to be disclosed therein,
that is reasonably necessary to permit the reoffer and sale of such
Transaction Party Affiliate's Conversion Shares pursuant to such
Reoffer Registration Statement. The Company shall cause the Conversion
Shares registered under any Registration Statement to be then listed
or quoted on the primary exchange or quotation system on which the
Common Stock is then listed or quoted.

          (d) Notice of Certain Events. The Company shall promptly
notify each Transaction Party Affiliate of, and confirm in writing,
the filing of a Reoffer Registration Statement relating to the
Conversion Shares of such Transaction Party Affiliate or any
Prospectus, amendment or supplement related thereto or any
post-effective amendment to such Reoffer Registration Statement and
the effectiveness of such 


<PAGE>

Reoffer Registration Statement and any post-effective amendment.

          At any time when a Prospectus included in a Reoffer
Registration Statement is required to be delivered under the
Securities Act by a Transaction Party Affiliate, the Company shall
immediately notify each Transaction Party Affiliate of the happening
of any event as a result of which the Prospectus included in such
Reoffer Registration Statement, as then in effect, includes an untrue
statement of a material fact or omits to state any material fact
required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading. In such event, the Company shall promptly prepare and
furnish to each applicable Transaction Party Affiliate a reasonable
number of copies of a supplement to or an amendment of such Prospectus
as may be necessary so that, as thereafter delivered to offerees of
such Transaction Party Affiliate's Conversion Shares, such Prospectus
shall not include an untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which
they are made, not misleading. The Company will, if necessary, amend
the Reoffer Registration Statement of which such Prospectus is a part
to reflect such amendment or supplement.

          Section 4.20 State Securities Laws.

          Subject to the conditions set forth in this Agreement, the
Company shall, in connection with the filing of any Registration
Statement hereunder, file such documents as may be necessary to
register or qualify the Conversion Shares to which such Registration
Statement relates (with respect to the issuance of such Conversion
Shares and, if applicable, the subsequent resale thereof) under the
securities or "blue sky" laws of such states as any Transaction Party
Affiliate offering such Conversion Shares may reasonably request, and
the Company shall use its best efforts to cause such filings to become
effective; provided, however, that the Company shall not be obligated
to qualify as a foreign corporation to do business under the laws of
any such state in which it is not then qualified or to file any
general consent to service of process in any such state. Once
effective, the Company shall use its best efforts to keep such filings
effective until the earlier of (a) the Reoffer Registration Expiration
Date or (b) in the case of a particular state, such Transaction Party
Affiliate has notified the Company that it no longer requires an
effective filing in such state in accordance with its original request
for filing.

          Section 4.30 Expenses.

          The Company shall bear all Registration Expenses incurred in
connection with the registration of the Conversion Shares pursuant to
this Agreement.

          Section 4.40 Indemnification by the Company.

          The Company agrees to indemnify each Transaction Party
Affiliate and its officers, directors, employees, agents,
representatives and Transaction Party Affiliates, and each person or
entity, if any, that controls such Transaction Party Affiliate within
the meaning of the Securities 


<PAGE>


Act, and each other person or entity, if any, subject to liability
under the Securities Act because of his, her or its connection with a
Transaction Party Affiliate (each, an "Indemnitee"), against any and
all losses, claims, damages, actions, liabilities, costs and expenses
(including without limitation reasonable fees, expenses and
disbursements of attorneys and other professionals), joint or several,
arising out of or based upon any violation by the Company of any rule
or regulation promulgated under the Securities Act applicable to the
Company and relating to action or inaction required of the Company in
connection with any Reoffer Registration Statement or the related
Prospectus relating to Conversion Shares offered by such Transaction
Party Affiliate, or upon any untrue or alleged untrue statement of
material fact contained in such Reoffer Registration Statement or
Prospectus, or any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they
were made, not misleading; provided, that the Company shall not be
liable to such Indemnitee or any person who participates as an
underwriter in the offering or sale of such Conversion Shares or any
other person, if any, who controls such underwriter within the meaning
of the Securities Act, in any such case to the extent that any such
loss, claim, damage, liability (or action or proceeding in respect
thereof) or expense arises out of or is based upon (i) an untrue
statement or alleged untrue statement or omission or alleged omission
made in any such Registration Statement or in any such Prospectus in
reliance upon and in conformity with information regarding such
Transaction Party Affiliate or its plan of distribution that was
furnished to the Company for use in connection with such Reoffer
Registration Statement or related Prospectus by such Transaction Party
Affiliate or (ii) such Transaction Party Affiliate's failure to send
or give a copy of the final, amended or supplemented Prospectus
furnished to such Transaction Party Affiliate by the Company at or
prior to the time such action is required by the Securities Act to the
person claiming an untrue statement or alleged untrue statement or
omission or alleged omission if such statement or omission was
corrected in such final, amended or supplemented Prospectus.

          Section 4.50 Agreements of Transaction Party Affiliates.

          The Company shall have no obligation or liability to any
Transaction Party Affiliate under this Article IV unless such
Transaction Party Affiliate shall have entered into a written
agreement with the Company or shall otherwise be obligated to the
Company (a) to cooperate with the Company and to furnish to the
Company all such information concerning its plan of distribution with
respect to its Conversion Shares, its ownership of Company securities
and other matters in connection with the preparation of a Reoffer
Registration Statement with respect to such Conversion Shares as the
Company may reasonably request, (b) to deliver or cause delivery of
the Prospectus contained in such Reoffer Registration Statement to any
purchaser of the shares covered by such Registration Statement from
such Transaction Party Affiliate, (c) to indemnify the Company, its
officers, directors, employees, agents, representatives and
Transaction Party Affiliates, and each person, if any, who controls
the Company within the meaning of the Securities Act, and each other
person, if any, subject to liability under the Securities Act because
of this connection with the Company, against any and all losses,
claims, damages, actions, liabilities, costs and expenses arising out
of or based upon (i) any untrue 

<PAGE>

statement or alleged untrue statement of material fact contained in
such Reoffer Registration Statement or the related Prospectus, or any
omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein, in
the light of the circumstances under which they were made, not
misleading, if and to the extent that such statement or omission
occurs from reliance upon and in conformity with written information
regarding such Transaction Party Affiliate that was furnished to the
Company in writing by such Transaction Party Affiliate specifically
for use therein, unless such statement or omission was corrected in
writing to the Company not less than three (3) business days prior to
the date of the final Prospectus (as supplemented or amended, as the
case may be) or (ii) the failure of such Transaction Party Affiliate,
through no fault of the Company, to deliver or cause to be delivered
the Prospectus contained in such Reoffer Registration Statement (as
amended or supplemented if applicable) furnished by the Company to
such Transaction Party Affiliate to any purchaser from such
Transaction Party Affiliate of the Conversion Shares to which such
Reoffer Registration Statement relates, (d) if requested by the
Company in the case of a Company-initiated non-underwritten offering,
or if requested by the managing underwriter in a Company-initiated
underwritten offering, not to effect any public sale or distribution
of any Conversion Shares, including a sale pursuant to Rule 144,
during the period of 60 days beginning 15 days prior to the proposed
offering date specified in such request; provided, however, that the
aggregate of all periods of restrictions on resale imposed on any
Transaction Party Affiliate as a result of requests under this Section
4.5(d) and of deferral or suspension of the Company's obligation to
cause a Registration Statement for the Conversion Shares of such
Transaction Party Affiliate or to amend or supplement such a
Registration Statement pursuant to Section 4.6(b) shall not exceed 90
days during any 12 month period, (e) following the effectiveness of
any Reoffer Registration Statement relating to Conversion Shares of
such Transaction Party Affiliate, not to effect any sales of such
Conversion Shares pursuant to such Reoffer Registration Statement at
any time after such Transaction Party Affiliate has received notice
from the Company to suspend sales as a result of the occurrence or
existence of any event referred to in Section 4.6(b) or so that the
Company may correct or update such Reoffer Registration Statement,
provided that such Transaction Party Affiliate may recommence
effecting sales of such Conversion Shares pursuant to such Reoffer
Registration Statement following further notice to such effect from
the Company, which notice shall be given by the Company not later than
five business days after the cessation of any such event, and (f)
incorporating the provisions of Section 4.7.

          Section 4.60 Suspension of Registration Requirement:
Restriction on Sale.

          (a) The Company shall promptly notify each Transaction Party
Affiliate, and confirm such notice in writing, of (i) the Company's
receipt of any notification with respect to the suspension of the
qualification of such Transaction Party Affiliate's Conversion Shares
for offer or sale in any jurisdiction or the initiation of any
proceedings for that purpose and (ii) the issuance by the SEC of any
stop order suspending the effectiveness of a Reoffer Registration
Statement with respect to such Transaction Party Affiliate's
Conversion Shares or the initiation of any proceedings for that
purpose. The Company shall use its best efforts to obtain the


<PAGE>


withdrawal of any order suspending the effectiveness of such Reoffer
Registration Statement or the qualification of such Conversion Shares
at the earliest possible moment.

          (b) Notwithstanding anything to the contrary set forth in
this Agreement, the Company may defer its obligation to cause a
Registration Statement to become effective or to amend or supplement a
Registration Statement for a period of not more than 60 days in the
event of (i) an underwritten primary offering by the Company if the
Company is advised by the managing underwriter of such offering that
the sale of Conversion Shares under such Registration Statement would
impair the pricing or commercial practicality of such offering, or
(ii) pending negotiations relating to, or consummation of, a
transaction or the occurrence of an event that would require
additional disclosure of material information by the Company in such
Registration Statement, as to which the Company has a bona fide
business purpose for preserving confidentiality or which renders the
Company unable to comply with SEC requirements and that would in each
case make it impractical or inadvisable to cause such Registration
Statement to become effective or to amend or supplement such
Registration Statement; provided, however, that the Company shall not
defer or suspend its obligation under this Agreement to cause a
Registration Statement to become effective or to amend or supplement a
Registration Statement pursuant to this Section 4.6(b) for an
aggregate period of more than 90 days during any 12 month period. The
Company shall notify each Holder of the existence and, in the case of
an event referred to in clause (i) of this Section 4.6 (b), the nature
of any such event.

          Section 4.70 Contribution.

          If the indemnification provided for in Sections 4.4 and
4.5(c) is unavailable to an indemnified party with respect to any
losses, claims, damages, actions, liabilities, costs or expenses
referred to therein or is insufficient to hold the indemnified party
harmless as contemplated therein, then the indemnifying party, in lieu
of indemnifying such indemnified party, shall contribute to the amount
paid or payable by such indemnified party as a result of such losses,
claims, damages, actions, liabilities, costs or expenses in such
proportion as is appropriate to reflect the relative fault of the
indemnifying party, on the one hand, and the indemnified party, on the
other hand, in connection with the statements or omissions that
resulted in such losses, claims, damages, actions, liabilities, costs
or expenses as well as any other relevant equitable considerations.
The relative fault of the indemnifying party, on the one hand, and of
the indemnified party on the other hand, shall be determined by
reference to, among other factors, whether the untrue or alleged
untrue statement of a material fact or omission to state a material
fact relates to information supplied by the indemnifying party or by
the indemnified party and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such
statement or omission; provided, however, that in no event shall the
obligation of any indemnifying party to contribute under this Section
4.7 exceed the amount that such indemnifying party would have been
obligated to pay by way of indemnification if the indemnification
provided for under Sections 4.4 or 4.5(c) had been available under the
circumstances.


<PAGE>


          The Company and the Holders agree that it would not be just
and equitable if contribution pursuant to this Section 4.7 were
determined by pro rata allocation or by any other method of allocation
that does not take account of the equitable considerations referred to
in the immediately preceding paragraph.

          Notwithstanding the provision of this Section 4.7, no
Transaction Party Affiliate shall be required to contribute any amount
in excess of the amount by which the gross proceeds from the sale of
such Transaction Party Affiliate's Conversion Shares exceeds the
amount of any damages that such Transaction Party Affiliate has
otherwise been required to pay by reason of such untrue or alleged
untrue statement or omission. No indemnified party guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to contribution from any
indemnifying party who was not guilty of such fraudulent
misrepresentation.

          Section 4.80 No Other Obligation to Register.

          Except as otherwise expressly provided in this Agreement,
the Company shall have no obligation to the Holders to register the
Conversion Shares under the Securities Act.

          Section 4.90 Exchange Act Compliance.

          The Company shall maintain registration of the Common Stock
under the Exchange Act and shall timely file all reports required to
be filed thereunder so that the current public information
requirements of paragraph (c) of Rule 144 shall continuously be
complied with.

          Section 4.10 Breach of Agreement

          No act or omission to act of the Company in contravention of
this Article IV shall be deemed a breach of the Company's obligations
hereunder if (a) such act or omission is cured within 30 days of
receipt of written notice from any Holder or First-Tier Transferee or
(b) in the case of any such act or omission that cannot be cured
within such 30-day period, the Company actively and diligently
attempts to cure such act or omission during such 30-day period and
such act or omission is cured within 30 days thereafter; provided,
however, that this Section 4.10 shall not apply to any failure to file
a Registration Statement within the time limits specified in Sections
4.1(a)(i), (ii) and (iii).

               purchaser or transferee is a member, of more than 9.8%

               Unit Holder, any UDR Unit Holder is a member, of more

               combination, liquidation or sale of the Company or

               used in Regulation 14A under the Exchange Act,
               disregarding clause (iv) of Rule 14a-1(l)(2) and
               including an exempt solicitation pursuant to Rule
               14a-2(b)(1)); or

               (vi) contest the validity or enforceability of this
               Section 5.1, except as a consequence of establishing
               the occurrence of any of the events specified in
               Sections 5.2(b)(ii), (iii), (iv) or (v).

anniversary of the date of this Agreement, the Preferred Holder will
not directly or indirectly:

               (i) sell or transfer any Securities to any Person,
               except (A) as a participant in a merger, consolidation
               or other business combination approved by the Board or
               (B) in a transaction on the NYSE or other market in
               which such Securities are traded, in which the identity
               of the buyer or transferee is not known by the seller
               or transferor in advance of the transaction, if such
               sale or transfer would result in Beneficial Ownership
               by the purchaser or transferee, or any Group of which,
               to the actual knowledge of the Preferred Holder, the
               purchaser or transferee is a member, of more than 9.8%
               of the number of shares of Common Stock outstanding at
               the time of such sale or transfer, determined on a

               Controlled Affiliates in the aggregate of more than 15%
               of the number of shares of Common Stock outstanding at

               in arrears for any quarter for a period exceeding five
               days,

               (ii) the occurrence of a Change of Control,

               (iii) the authorization by the Board (with the director
               or directors nominated and serving pursuant to Section
               5.9 of the Merger Agreement, if any, voting against) of
               the direct or indirect solicitation of offers with
               respect to any merger, consolidation, other business
               combination, liquidation or sale of the Company or all
               or substantially all of its assets or any other similar
               extraordinary transaction (any of the foregoing, other
               than any transaction in which the Company is the
               surviving and acquiring entity and in which (A) the
               only other parties to the transaction are subsidiaries
               or Controlled Affiliates of the Company or (B) the
               business or assets acquired do not, or would not
               reasonably be expected to, have a value greater than
               50% of the assets of the Company and its subsidiaries,
               consolidated, prior to such transaction, a "Covered
               Transaction"), it being understood that mere direction
               by the Board that the officers of the Company or a
               committee of the Board review and report on a proposal
               originated by any officer or director of the Company or
               by a third party that might result in a solicitation of
               offers shall not, without more, be deemed a
               "solicitation of offers," provided the director or
               directors nominated and serving pursuant to Section 5.9
               of the Merger Agreement, if any, receive notice of and
               have the opportunity to participate in any meeting of
               the Board at which such a direction is made or the
               report of the officers of the Company or such committee
               of the Board is presented,

               (iv) the written submission by any person or Group
               other than the Preferred Holder of a proposal to the
               Company (including the Board and any agent,
               representative or Affiliate of the Company) with
               respect to, or otherwise expressing interest in
               pursuing, a Covered Transaction, unless, as soon as
               practicable after receipt of any such proposal, the
               Board determines that such proposal is not in the best
               interests of the Company and its shareholders and
               continues to reject such proposal as a result of such
               determination,

               (v) in connection with any actual or proposed Covered
               Transaction, the termination of any shareholder rights
               plan or amendment of the articles of incorporation or
               bylaws of the Company to delete staggered terms of
               directors, supermajority voting of the Company's
               shareholders, "excess share" provisions, or other
               similar provisions which would reasonably be expected
               to impede the consummation of such Covered Transaction,

               (vi) any breach of Section 5.9 of the Merger Agreement,

               (vii) the initiation by the Company or any of its
               Affiliates of any action, suit or other legal
               proceeding against the Preferred Holder, any of 

<PAGE>


               its Affiliates or any of their respective officers or
               directors with respect to any matter unrelated to the
               express terms of this Agreement and the related documents
               and the transactions contemplated thereby, unless such
               action, suit or legal proceeding is authorized by the Board
               at a meeting of which the director or directors nominated
               and serving pursuant to Section 5.9 of the Merger Agreement,
               if any, receive notice and in which they have the
               opportunity to participate, provided that if there shall be
               a final judgment on the merits in favor of the Preferred
               Holder or such Affiliate in any such action, suit or legal
               proceeding that is so authorized by the Board, a Standstill
               Termination Event shall exist even though such judgment may
               be subject to further appeal,

               (viii) the distribution by the Preferred Holder of all
               of its Preferred Shares and Conversion Shares pursuant
               to Section 3.1(c), provided that such Standstill
               Termination Event shall not affect any agreement
               entered into by a Permitted Preferred Share Transferee
               pursuant to Section 3.1(c)(ii), and

               (ix) the date on which the Preferred Holder ceases
               (otherwise than as a result of a distribution of
               Preferred Shares and Conversion Shares pursuant to
               Section 3.1(c)) to be the Beneficial Owner of
               Securities having an aggregate market value of more
               than 5% of Average Market Capitalization. For purposes
               of this Section 5.2(b) (ix), the "market value" of
               Conversion Shares shall be determined by reference to
               the closing sale price of the Common Stock on the day
               preceding the determination date, and the "market
               value" of Preferred Shares shall be the Series D
               Redemption Price of the Preferred Shares provided in
               the Company's Articles of Incorporation on the
               determination date.
