                              ARCHSTONE-SMITH TRUST
                                     BYLAWS

                       ARTICLE I. MEETINGS OF SHAREHOLDERS

         Section 1. Place. All meetings of shareholders ("Shareholders") of
Archstone-Smith Trust (the "Trust") shall be held at the principal office of the
Trust or at such other place within the United States as shall be stated in the
notice of the meeting.

         Section 2. Annual Meetings. Failure to hold an annual meeting does not
invalidate the Trust's existence or affect any otherwise valid acts of the
Trust.

         Section 3. Special Meetings. The Chairman of the Board, President,
Chief Executive Officer or Board of Trustees may call a special meeting of the
Shareholders. Requests by Shareholders for special meetings shall state the
purpose of such meeting and the matters proposed to be acted on at such meeting.
The Secretary shall inform the requesting Shareholders of the reasonably
estimated cost of preparing and mailing notice of the meeting and, upon payment
to the Trust by such Shareholders of such costs, the Secretary shall give notice
of the meeting. Unless requested by the Shareholders entitled to cast a majority
of the votes entitled to be cast at such meeting, a special meeting need not be
called to consider any matter which is substantially the same as a matter voted
on at any meeting of Shareholders held during the preceding twelve months. The
Board has the sole power to fix (i) the record date for determining shareholders
entitled to notice of and to vote at the special meeting and (ii) the date, time
and place of the special meeting.

         Section 4. Notice. Notice of any meeting may be given in any manner
permitted by Maryland law. If mailed, notices of meetings of Shareholders shall
be deemed to be given when deposited in the United States mail addressed to the
Shareholder at his or her post office address as it appears on the records of
the Trust, with postage thereon prepaid.

         Section 5. Scope of Notice. Any business of the Trust may be transacted
at an annual meeting of Shareholders without being specifically designated in
the notice, except such business as is required by any statute to be stated in
such notice. No business shall be transacted at a special meeting of
Shareholders except as specifically designated in the notice.

         Section 6. Waiver of Notice. Whenever any notice of a meeting of
Shareholders is required to be given pursuant to the Trust's Declaration of
Trust (as amended, supplemented or restated from time to time, the "Declaration
of Trust") or these Bylaws or pursuant to applicable law, a waiver thereof in
writing, signed by the Shareholder or Shareholders entitled to such notice,
whether before or after the time stated therein, shall be deemed equivalent to
the giving of such notice. Neither the business to be transacted at nor the
purpose of any meeting need be set forth in the waiver of notice, unless
specifically required by statute. The attendance of any Shareholder at any
meeting shall constitute a waiver of notice of such meeting.

<PAGE>

         Section 7.  Organization. At every meeting of Shareholders, the
Chairman of the Board, if there is one (or any Co-Chairman of the Board, if
there is more than one), shall conduct the meeting or, in the case of vacancy in
office or absence of the Chairman of the Board (or all Co-Chairmen of the
Board), one of the following officers present shall conduct the meeting in the
order stated: the President, the Managing Directors in their order of rank and
seniority, the Vice Presidents in their order of rank and seniority, or a
chairman chosen by the Shareholders entitled to cast a majority of the votes
which all Shareholders present in person or by proxy are entitled to cast, shall
act as chairman, and the Secretary, or, in his or her absence, an Assistant
Secretary, or in the absence of both the Secretary and Assistant Secretaries, a
person appointed by the chairman shall act as secretary. At any Shareholders'
meeting, the chairman shall determine the construction or interpretation of
these Bylaws, or any part thereof, and the ruling of the chairman shall be
final.

         Section 8.  Quorum. Unless otherwise provided in the Declaration of
Trust or these Bylaws, with respect to any matter to be considered at any
meeting of Shareholders, the presence in person or by proxy of Shareholders
entitled to cast a majority of all the votes entitled to be cast with respect to
such matter shall constitute a quorum. If a quorum is not present at any meeting
of the Shareholders, the Shareholders entitled to vote at such meeting, present
in person or by proxy, shall have the power to adjourn such meeting from time to
time to a date not more than 120 days after the original record date without
notice other than announcement at such meeting. At any such adjourned meeting at
which a quorum shall be present, any business may be transacted which might have
been transacted at the meeting as originally notified. A plurality of all the
votes cast by Shareholders entitled to vote with respect to the election of
Trustees at a meeting duly called at which a quorum is present shall be
sufficient to elect a Trustee.

         Section 9.  Proxies. A Shareholder may cast the votes entitled to be
cast by the shares ("Shares") of the Trust owned of record by him, either in
person or by proxy in any manner authorized by law, by the Shareholder or by his
or her duly authorized attorney in fact. Such proxy shall be filed with the
Secretary before or at the time of the meeting. A Shareholder may authorize
another person to act as proxy by transmitting, or authorizing the transmission
of, an authorization by telegram, cablegram, datagram, electronic mail or any
other electronic or telephonic means to the person authorized to act as proxy or
to any other person authorized to receive the proxy authorization on behalf of
the person authorized to act as proxy, including a proxy solicitation firm or
proxy support service organization. No proxy shall be valid after eleven months
from the date of its execution, unless otherwise provided in the proxy.

         Section 10. Voting of Shares by Certain Holders.

         (a) Shares Held by an Entity. Shares registered in the name of a
corporation, partnership, trust or other entity, if entitled to be voted, may be
voted by the president or a vice president, a general partner or trustee
thereof, as the case may be, or a proxy appointed by any of the foregoing
individuals, unless some other person who has been appointed to vote such Shares
pursuant to a bylaw or a resolution of the governing body of such corporation or
other entity or agreement of the partners of a partnership presents a certified
copy of such bylaw, resolution or

                                       2

<PAGE>

agreement, in which case such person may vote such Shares. Any director or other
fiduciary may vote Shares registered in his or her name as such fiduciary,
either in person or by proxy.

         (b) Shares Held by Certain Persons. Shares registered in the name of a
person adjudged incompetent may be voted and all rights incident thereto may be
exercised only by his guardian, in person or by proxy. Shares registered in the
name of a deceased person may be voted and all rights incident thereto may be
exercised only by his executor or administrator, in person or by proxy. Shares
registered in the name of a minor may be voted and all rights incident thereto
may be exercised by his guardian, in person or by proxy, or in the absence of
such representation by his guardian, by the minor, in person or by proxy,
whether or not the Trust has notice, actual or constructive, of the minority or
the appointment of a guardian, and whether or not a guardian has in fact been
appointed.

         (c) Shares Held by Two or More Persons. Shares registered in the names
of two or more persons shall be voted or represented in accordance with the vote
or consent of the majority of the persons in whose names the Shares stand. If
only one such person is present in person or by proxy, he or she may vote all
the Shares, and all the Shares standing in the names of such persons are
represented for the purpose of determining a quorum. This procedure also applies
to the voting of Shares by two or more administrators, executors, trustees or
other fiduciaries, unless the instrument or order of court appointing them
otherwise directs.

         (d) Shares Held by the Trust. Shares of the Trust directly or
indirectly owned by it shall not be voted at any meeting and shall not be
counted in determining the total number of outstanding Shares entitled to be
voted at any given time, unless they are held by it in a fiduciary capacity, in
which case they may be voted and shall be counted in determining the total
number of outstanding Shares at any given time.

         (e) Certifications of Beneficial Ownership. The Board of Trustees (the
"Board") may adopt by resolution a procedure by which a Shareholder may certify
in writing to the Trust that any Shares registered in the name of the
Shareholder are held for the account of a specified person other than the
Shareholder. The resolution shall set forth: the class of Shareholders who may
make the certification; the purpose for which the certification may be made; the
form of certification; the information to be contained in it; if the
certification is with respect to a record date or closing of the Share transfer
books, the time after the record date or closing of the Share transfer books
within which the certification must be received by the Trust; and any other
provisions with respect to the procedure which the Board considers necessary or
desirable. On receipt of such certification, the person specified in the
certification shall be regarded as, for the purposes set forth in the
certification, the Shareholder of record of the specified Shares in place of the
Shareholder who makes the certification.

         Section 11. Inspectors. At any meeting of Shareholders, the chairman of
the meeting may, or upon the request of any Shareholder shall, appoint one or
more persons as inspectors for such meeting. Such inspectors shall ascertain and
report the number of Shares represented at the meeting

                                       3

<PAGE>

based on their determination of the validity and effect of proxies, count all
votes, report the results and perform such other acts as are proper to conduct
the election and voting with impartiality and fairness to all the Shareholders.
Each report of an inspector shall be in writing and signed by him or by a
majority of them if there is more than one inspector acting at such meeting. If
there is more than one inspector, the report of a majority shall be the report
of the inspectors. The report of the inspector or inspectors on the number of
Shares represented at the meeting and the results of the voting shall be prima
facie evidence thereof.

         Section 12. Action Without Meetings. Any action required or permitted
to be taken at a meeting of Shareholders may be taken without a meeting if there
is filed with the records of Shareholders' meetings a unanimous written consent
which sets forth the action and is signed by each Shareholder entitled to vote
on the matter.

         Section 13. Nominations and Proposals by Shareholders.

         (a)      Annual Meetings of Shareholders.

                  (1)  Nominations of persons for election to the Board and the
proposal of business to be considered by the Shareholders may be made at an
annual meeting of Shareholders (i) pursuant to the Trust's notice of a meeting,
(ii) by or at the direction of the Board or (iii) by any Shareholder of the
Trust who was a Shareholder of record at the time of the giving of notice
provided for in this Section 12(a) and at the time of the annual meeting, who is
entitled to vote at the meeting and who complied with the notice procedures set
forth in this Section 12(a).

                  (2)  For nominations or other business to be properly brought
before an annual meeting by a Shareholder pursuant to clause (iii) of paragraph
(a)(1) of this Section 12, the Shareholder must have given timely notice thereof
in writing to the Secretary and such nomination or other business must otherwise
be a proper matter for action by Shareholders. To be timely, a Shareholder's
notice shall be delivered to the Secretary at the principal executive offices of
the Trust not less than 90 days nor more than 120 days prior to the first
anniversary of the date of the proxy statement released to shareholders in
connection with the preceding year's annual meeting of shareholders; provided,
however, that if the date of the annual meeting is advanced by more than 30 days
or delayed by more than 60 days from such anniversary of the preceding year's
annual meeting, notice by the Shareholder to be timely must be so delivered (x)
not more than 120 days prior to the first anniversary of the date of the proxy
statement released to shareholders in connection with the preceding year's
annual meeting nor less than 90 days prior to the first anniversary of the date
of the proxy statement released to shareholders in connection with the preceding
year's annual meeting or (y) not later than the close of business on the tenth
day following the day on which public announcement of the date of such meeting
is first made by the Trust. Such Shareholder's notice shall set forth (i) as to
each person whom the Shareholder proposes to nominate for election or reelection
as a Trustee all information relating to such person which is required to be
disclosed in solicitations of proxies for election of Trustees, or is otherwise
required, in each case pursuant to Regulation 14A under the Securities Exchange
Act of 1934, as amended (the "Exchange Act") (including such

                                       4

<PAGE>

person's written consent to being named in the proxy statement as a nominee and
to serving as a Trustee if elected); (ii) as to any other business which the
Shareholder proposes to bring before the meeting, a brief description of the
business desired to be brought before the meeting, the reasons for conducting
such business at the meeting and any material interest in such business of such
Shareholder and of the beneficial owner, if any, on whose behalf the proposal is
made; and (iii) as to the Shareholder giving the notice and the beneficial
owner, if any, on whose behalf the nomination or proposal is made, (x) the name
and address of such Shareholder, as they appear on the Trust's books, and of
such beneficial owner, (y) the number of Shares of each class of the Trust which
are owned beneficially and of record by such Shareholder and such beneficial
owner and (z) in the case of a nomination, (A) a description of all arrangements
or understandings between such Shareholder and each proposed nominee and any
other person or persons (including their names) pursuant to which the
nomination(s) are to be made by such Shareholder, (B) a representation that such
Shareholder intends to appear in person or by proxy at the meeting, if there is
a meeting, to nominate the persons named in its notice and (C) any other
information relating to such Shareholder that would be required to be disclosed
in a proxy statement or other filings required to be made in connection with
solicitations of proxies for election of Trustees pursuant to Section 14 of the
Exchange Act and the rules and regulations promulgated thereunder.

         (3) Notwithstanding anything in the second sentence of paragraph
(a)(2) of this Section 12 to the contrary, if the number of Trustees to be
elected to the Board is increased and there is no public announcement by the
Trust naming all of the nominees for Trustee or specifying the size of the
increased Board at least 100 days prior to the first anniversary of the date of
the proxy statement released to shareholders in connection with the preceding
year's annual meeting of shareholders, a Shareholder's notice required by this
Section 12(a) shall also be considered timely, but only with respect to nominees
for any new positions created by such increase, if it shall be delivered to the
Secretary at the principal executive offices of the Trust not later than the
close of business on the tenth day following the day on which such public
announcement is first made by the Trust.

     (b) Special Meetings of Shareholders. Only such business shall be conducted
at a special meeting of Shareholders as shall have been brought before the
meeting pursuant to the Trust's notice of meeting. Nominations of persons for
election to the Board may be made at a special meeting of Shareholders at which
Trustees are to be elected (i) pursuant to the Trust's notice of meeting, (ii)
by or at the direction of the Board or (iii) provided that the Board has
determined that Trustees shall or may be elected at such special meeting, by any
Shareholder of the Trust who was a Shareholder of record both at the time of
giving of notice provided for in this Section 12(b) and at the time of the
special meeting, who is entitled to vote at the meeting and who complied with
the notice procedures set forth in this Section 12(b). If the Trust calls a
special meeting of Shareholders for the purpose of electing one or more Trustees
to the Board, any such Shareholder may nominate a person or persons (as the case
may be) for election to such position as specified in the Trust's notice of
meeting, if the Shareholder's notice containing the information required by
paragraph (a)(2) of this Section 12 shall be delivered to the Secretary at the
principal executive offices of the Trust (A) not more than 120 days prior to
such special meeting nor less than 90 days prior to such special meeting

                                       5

<PAGE>

or (B) not later than the close of business on the tenth day following the day
on which public announcement is first made of the date of the special meeting
and of the nominees proposed by the Board to be elected at such meeting.

         (c)      General.

                  (1) Only such persons who are nominated in accordance with the
procedures set forth in this Section 12 shall be eligible to serve as Trustees
and only such business shall be conducted at a meeting of Shareholders as shall
have been brought before the meeting in accordance with the procedures set forth
in this Section 12. The chairman of the meeting shall have the power and duty to
determine whether a nomination or any business proposed to be brought before the
meeting was made or proposed in accordance with the procedures set forth in this
Section 12 and, if any proposed nomination or business is not in compliance with
this Section 12, to declare that such nomination or proposal shall be
disregarded.

                  (2) For purposes of this Section 12, "public announcement"
shall mean disclosure in a press release reported by the Dow Jones News Service,
Associated Press or comparable news service or in a document publicly filed by
the Trust with the Securities and Exchange Commission pursuant to Section 13, 14
or 15(d) of the Exchange Act.

                  (3) Notwithstanding the foregoing provisions of this Section
12, a Shareholder shall also comply with all applicable requirements of Maryland
law and of the Exchange Act and the rules and regulations thereunder with
respect to the matters set forth in this Section 12. Nothing in this Section 12
shall be deemed to affect any rights of Shareholders to request inclusion of,
nor any rights of the Trust to omit, proposals in the Trust's proxy statement
pursuant to Rule 14a-8 under the Exchange Act.

     Section 14.  Voting by Ballot. Voting on any question or in any election
may be by voice unless the presiding officer shall order or any Shareholder
shall demand that voting be by ballot.

                              ARTICLE II. TRUSTEES

     Section 1.   Annual And Regular Meetings. An annual meeting of the Board
shall be held immediately after and at the same place as the annual meeting of
Shareholders, no notice other than this bylaw being necessary. The Board may
provide, by resolution, the time and place, either within or without the State
of Maryland, for the holding of regular meetings of the Board without other
notice than such resolution.

     Section 2.   Special Meetings. Special meetings of the Board may be called
by or at the request of the Chairman of the Board (or any Co-Chairman of the
Board, if there is more than one), the Chief Executive Officer or by a majority
of the Trustees then in office. The person or persons authorized to call special
meetings of the Board may fix any place, either within or without the State of
Maryland, as the place for holding any special meeting of the Board called by
them.

                                       6

<PAGE>

         Section 3. Notice. Notice of any special meeting of the Board shall be
delivered personally or by telephone, facsimile transmission, United States mail
or courier to each Trustee at his or her business or residence address. Notice
by personal delivery, by telephone or a facsimile transmission shall be given at
least two days prior to the meeting. Notice by mail shall be given at least five
days prior to the meeting and shall be deemed to be given when deposited in the
United States mail properly addressed, with postage thereon prepaid. Telephone
notice shall be deemed to be given when the Trustee is personally given such
notice in a telephone call to which he is a party. Facsimile transmission notice
shall be deemed to be given upon completion of the transmission of the message
to the number given to the Trust by the Trustee and receipt of a completed
transmission indicating receipt. Neither the business to be transacted at, nor
the purpose of, any annual, regular or special meeting of the Board need be
stated in the notice, unless specifically required by statute or these Bylaws.

         Section 4. Waiver of Notice. Whenever any notice of a meeting of the
Board or any committee thereof is required to be given pursuant to the
Declaration of Trust or these Bylaws or pursuant to applicable law, a waiver
thereof in writing, signed by the Trustee or Trustees entitled to such notice,
whether before or after the time stated therein, shall be deemed equivalent to
the giving of such notice. Neither the business to be transacted at nor the
purpose of any meeting need be set forth in the waiver of notice, unless
specifically required by statute. The attendance of any Trustee at any meeting
shall constitute a waiver of notice of such meeting.

         Section 5. Organization. A majority of the Board may designate or elect
a Trustee to preside at Board meetings. In the absence of such designation or
election, the Chairman of the Board (or any Co-Chairman of the Board, if there
is more than one) or the Chief Executive Officer shall preside at Board
meetings; in his absence, the Trustees present at each meeting shall elect one
of the Trustees present as chairman. All rules of conduct adopted and used at
Board meetings shall be determined by the chairman, whose ruling on all
procedural matters shall be final.

         Section 6. Quorum. A majority of the Trustees shall constitute a quorum
for the transaction of business at any meeting of the Board of Trustees,
provided that if less than a quorum of Trustees is present at a meeting, a
majority of the Trustees present may adjourn the meeting from time to time
without further notice, and further provided that if, pursuant to the
Declaration of Trust or these Bylaws, the vote of a majority of a particular
group of Trustees is required for action, a quorum must also include a majority
of such group. The Trustees present at a meeting which has been duly called and
convened may continue to transact business until adjournment, notwithstanding
the withdrawal of enough Trustees to leave less than a quorum.

         Section 7. Voting at Meetings. Voting at Board meetings may be
conducted orally, by show of hands, or, if requested by any Trustee, by written
ballot. The results of all voting shall be recorded by the Secretary in the
minute book.

         Section 8. Telephone Meetings. Trustees may participate in a meeting by
means of a conference telephone or similar communications equipment if all
persons participating in the

                                       7

<PAGE>

meeting can hear each other at the same time. Participation in a meeting by
these means shall constitute presence in person at the meeting.

         Section 9.  Compensation. Trustees shall not receive any stated salary
for their services as Trustees but, by resolution of the Board, may receive
fixed sums per year and/or per meeting and/or per visit to real property owned
or to be acquired by the Trust and for any service or activity they performed or
engaged in as Trustees. Trustees may be reimbursed for expenses of attendance,
if any, at each annual, regular or special meeting of the Board or of any
committee thereof and for their expenses, if any, in connection with each
property visit and any other service or activity they performed or engaged in as
Trustees; but nothing herein contained shall be construed to preclude any
Trustees from serving the Trust in any other capacity and receiving compensation
therefor.

         Section 10. Distributions. Dividends and other distributions upon the
shares of beneficial interest of the Trust may be authorized and declared by the
Trustees, subject to the provisions of law and the Declaration of Trust. In
determining the amount of any distribution, the Trustees may establish, modify,
and reverse such reserves for contingencies (including, without limitation, for
equalizing distributions, for property repair and maintenance, or for such other
purposes as the Trustees shall determine to be appropriate) as they shall
determine in good faith to be appropriate.

         Section 11. Investment Policy. Subject to the provisions of the
Declaration of Trust, the Board may from time to time adopt, amend, revise or
terminate any policy or policies with respect to investments by the Trust as it
shall deem appropriate in its sole discretion.

         Section 12. Loss of Deposits. No Trustee shall be liable for any loss
which may occur by reason of the failure of the bank, trust company, savings and
loan association or other institution with whom moneys or shares have been
deposited.

         Section 13. Surety Bonds. Unless required by law, no Trustee shall be
obligated to give any bond or surety or other security for the performance of
any of his or her duties.

         Section 14. Reliance. Each Trustee, officer, employee and agent of the
Trust shall, in the performance of his or her duties with respect to the Trust,
be fully justified and protected with regard to any act or failure to act in
reliance in good faith on the books of account or other records of the Trust, on
an opinion of counsel or on reports made to the Trust by any of its officers or
employees or by the adviser, accountants, appraisers or other experts or
consultants selected by the Board or officers of the Trust, regardless of
whether such counsel or expert may also be a Trustee.

         Section 15. Certain Rights of Trustees, Officers, Employees And Agents.
The Trustees shall have no responsibility to devote their full time to the
affairs of the Trust. Any Trustee or officer, employee or agent of the Trust, in
his or her personal capacity or in a capacity as an affiliate, employee or agent
of any other person, or otherwise, may have business interests and engage in
business activities similar to or in addition to or in competition with those of
or relating to the Trust.

                                       8

<PAGE>

       Section 16.   Duties of Trustees. Except to the extent that the Trustees
are subject to a different standard under Maryland law or the Declaration of
Trust, the Trustees shall perform their duties as Trustees or members of
committees of Trustees in accordance with Section 2-405.1 of the Maryland
General Corporation Law and may rely on information, opinions, reports, or
statements as contemplated by Section 2-405.1.

       Section 17.   Presumption of Assent. A Trustee who is present at a
meeting of the Board of Trustees at which action on any matter is taken on
behalf of the Trust shall be presumed to have assented to such action unless
such Trustee announces his or her dissent at the meeting and (a) such Trustee's
dissent is entered into the minutes of the meeting, (b) such Trustee files his
or her written dissent to such action with the secretary of the meeting before
adjournment thereof, or (c) such Trustee forwards his or her written dissent, by
certified mail, return receipt requested, bearing a postmark from the United
States Postal Service, to the secretary of the meeting or the Secretary of the
Trust within 24 hours after the meeting is adjourned. Such right to dissent
shall not apply to a trustee who voted in favor of such action or failed to make
his or her dissent known at the meeting.

                             ARTICLE III. COMMITTEES

       Section 1.    Number, Tenure And Qualifications. The Board may appoint
from among its members an Executive Committee, an Audit Committee, an Executive
Compensation Committee, an Investment Committee and other committees, composed
of one or more Trustees, to serve at the pleasure of the Board.

       Section 2.    Meetings. Notice of committee meetings shall be given in
the same manner as notice for special meetings of the Board. A majority of the
members of the committee shall constitute a quorum for the transaction of
business at any meeting of the committee. The Board may designate a chairman of
any committee and such chairman or any two members of any committee may fix the
time and place of its meeting unless the Board shall otherwise provide. In the
absence of any member of any such committee, the members thereof present at any
meeting, whether or not they constitute a quorum, may appoint another Trustee to
act in the place of such absent member. Each committee shall keep minutes of its
proceedings.

       Section 3.    Telephone Meetings. Members of a committee of the Board may
participate in a meeting by means of a conference telephone or similar
communications equipment if all persons participating in the meeting can hear
each other at the same time. Participation in a meeting by these means shall
constitute presence in person at the meeting.

       Section 4.    Informal Action by Committees. Any action required or
permitted to be taken at any meeting of a committee of the Board may be taken
without a meeting, if a consent in writing to such action is signed by each
member of the committee and such written consent is filed with the minutes of
proceedings of such committee.

                                       9

<PAGE>

       Section 5.    Vacancies. Subject to the provisions hereof, the Board
shall have the power at any time to change the membership of any committee, to
fill all vacancies, to designate alternate members to replace any absent or
disqualified member or to dissolve any such committee.

                              ARTICLE IV. OFFICERS

       Section 1.    General Provisions. The officers of the Trust shall be
elected annually by the Board at the first meeting of the Board held after each
annual meeting of Shareholders, except that the Chairman of the Board (or any
Co-Chairman of the Board, if there is more than one) or the Chief Executive
Officer may appoint a President, a Chief Operating Officer, a Chief Financial
Officer, a Treasurer, a President of each division of the Trust, a Chairman of
each division of the Trust, and one or more Managing Directors, Vice Presidents,
Assistant Secretaries and Assistant Treasurers, or such other officers as the

                           ARTICLE V. INDEMNIFICATION

       Section 1.    Procedure. Any indemnification, or payment of expenses in
advance of the final disposition of any proceeding, shall be made promptly, and
in any event within 60 days, upon the written request of the Trustee or officer
entitled to seek indemnification (the "Indemnified Party"). The right to
indemnification and advances hereunder shall be enforceable by the Indemnified
Party in any court of competent jurisdiction, if (i) the Trust denies such
request, in whole or in part, or (ii) no disposition thereof is made within 60
days. The Indemnified Party's costs and expenses incurred in connection with
successfully establishing his or her right to indemnification, in whole or in
part, in any such action shall also be reimbursed by the Trust. It shall be a
defense to any action for advance of expenses that (a) a determination has been
made that the facts then known to those making the determination would preclude
indemnification or (b) the Trust has not received both (i) an undertaking as
required by law to repay such advances if it shall ultimately be determined that
the standard of conduct has not been met and (ii) a written affirmation by the
Indemnified Party of such Indemnified Party's good faith belief that the
standard of conduct necessary for indemnification by the Trust has been met.

       Section 2.    Exclusivity, Etc. The indemnification and advance of
expenses provided by the Declaration of Trust and these Bylaws shall not be
deemed exclusive of any other rights to which a person seeking indemnification
or advance of expenses may be entitled under any law (common or statutory), or
any agreement, vote of Shareholders or disinterested Trustees or other provision
which is consistent with law, both as to action in his or her official capacity
and as to action in another capacity while holding office or while employed by
or acting as agent for the Trust, shall continue in respect of all events
occurring while a person was a Trustee or officer after such person has ceased
to be a Trustee or officer, and shall inure to the benefit of the estate, heirs,
executors and administrators of such person. All rights to indemnification and
advancement of expenses under the Declaration of Trust and these Bylaws shall be
deemed to be a contract between the Trust and each Trustee or officer of the
Trust who serves or served in such capacity at any time while such provisions
are in effect. Nothing herein shall prevent the amendment of these Bylaws,
provided that no such amendment shall diminish the rights of any person
hereunder with respect to events occurring or claims made before its adoption or
as to claims made after its adoption in respect of events occurring before its
adoption. Any repeal or modification of these Bylaws shall not in any way
diminish any rights to indemnification or advancement of expenses of such
Trustee or officer of the obligations of the Trust arising hereunder with
respect to events occurring, or claims made, while these Bylaws or any provision
hereof is in effect.

                      ARTICLE VI. CONTRACTS AND ACCOUNTING

       Section 1.    Contracts. The Board may authorize any officer or agent to
enter into any contract or to execute and deliver any instrument in the name of
and on behalf of the Trust and such authority may be general or confined to
specific instances. Any agreement, deed, mortgage, lease or other document
executed by one or more of the Trustees or by an authorized person shall be
valid and binding on the Board and on the Trust when authorized or ratified by
action of the Board.

                                       13

<PAGE>

       Section 2.    Checks And Drafts. All checks, drafts or other orders for
the payment of money, notes or other evidences of indebtedness issued in the
name of the Trust shall be signed by such officer or agent of the Trust in such
manner as shall from time to time be determined by the Board.

       Section 3.    Deposits. All funds of the Trust not otherwise employed
shall be deposited from time to time to the credit of the Trust in such banks,
trust companies or other depositories as the Board may designate.

       Section 4.    Books and Records. The Trust shall keep correct and
complete books and records of its accounts and transactions and minutes of the
proceedings of its Shareholders and Board and of any executive or other
committee when exercising any of the powers of the Board. The books and records
of the Trust may be in written form or in any other form which can be converted
within a reasonable time into written form for visual inspection. Minutes shall
be recorded in written form but may be maintained in the form of a reproduction.
The original or a certified copy of the Bylaws shall be kept at the principal
office of the Trust.

       Section 5.    Fiscal Year. The fiscal year of the Trust shall be the
twelve months ending December 31 in each year, unless otherwise provided by the
Board.

                               ARTICLE VII. SHARES

       Section 1.    Certificates. Each Shareholder shall be entitled to a
certificate or certificates which shall represent and certify the number of
Shares of each class held by him or her in the Trust; provided, however, that
the Board may provide by resolution or resolutions that some or all of any class
or series of Shares shall be uncertificated. Each certificate shall be signed by
the Chairman of the Board (or any Co-Chairman of the Board, if there is more
than one), the President or a Vice President and countersigned by the Secretary
or an Assistant Secretary or the Treasurer or an Assistant Treasurer and may be
sealed with the seal, if any, of the Trust. The signatures may be either manual
or facsimile. Certificates shall be consecutively numbered; and if the Trust
shall, from time to time, issue several classes of Shares, each class may have
its own number series. A certificate is valid and may be issued whether or not
an officer who signed it is still an officer when it is issued. Each certificate
representing Shares which are restricted as to their transferability or voting
powers, which are preferred or limited as to their dividends or as to their
allocable portion of the assets upon liquidation or which are redeemable at the
option of the Trust, shall have a statement of such restriction, limitation,
preference or redemption provision, or a summary thereof, plainly stated on the
certificate. If the Trust has authority to issue Shares of more than one class,
the certificate shall contain on the face or back a full statement or summary of
the designations and any preferences, conversion and other rights, voting
powers, restrictions, limitations as to dividends and other distributions,
qualifications and terms and conditions of redemption of each class of Shares
and, if the Trust is authorized to issue any preferred or special class in
series, the differences in the relative rights and preferences between the
Shares of each series to the extent they have been set and the authority of the
Board to set the relative rights and preferences of subsequent series. In lieu
of such

                                       14

<PAGE>

statement or summary, the certificate may state that the Trust will furnish a
full statement of such information to any Shareholder upon request and without
charge. If any class of Shares is restricted by the Trust as to transferability,
the certificate shall contain a full statement of the restriction or state that
the Trust will furnish information about the restrictions to the Shareholder on
request and without charge.

       Section 2.    Transfers. Upon surrender to the Trust or the transfer
agent of the Trust of a Share certificate duly endorsed or accompanied by proper
evidence of succession, assignment or authority to transfer, the Trust shall
issue a new certificate to the person entitled thereto, cancel the old
certificate and record the transaction on its books. Notwithstanding the
foregoing, transfers of Shares of any class will be subject in all respects to
the Declaration of Trust and all of the terms and conditions contained therein.

       Section 3.    Replacement Certificate. Any officer designated by the
Board may direct a new certificate to be issued in place of any certificate
previously issued by the Trust alleged to have been lost, stolen or destroyed
upon the making of an affidavit of that fact by the person claiming the
certificate to be lost, stolen or destroyed. When authorizing the issuance of a
new certificate, an officer designated by the Board may, in his or her
discretion and as a condition precedent to the issuance thereof, require the
owner of such lost, stolen or destroyed certificate or the owner's legal
representative to advertise the same in such manner as he or she shall require
and/or to give bond, with sufficient surety, to the Trust to indemnify it
against any loss or claim which may arise as a result of the issuance of a new
certificate.

       Section 4.    Closing of Transfer Books or Fixing of Record Date.

       (a)    Fixing of Record Date. The Board may set, in advance, a record
date for the purpose of determining Shareholders entitled to notice of or to
vote at any meeting of Shareholders or determining Shareholders entitled to
receive payment of any dividend or the allotment of any other rights, or in
order to make a determination of Shareholders for any other proper purpose. Such
date, in any case, shall not be prior to the close of business on the day the
record date is fixed and shall be not more than 90 days, and in the case of a
meeting of the Shareholders not less than ten days, before the date on which the
particular action requiring such determination of Shareholders of record is to
be held or taken. In lieu of fixing a record date, the Board may provide that
the Share transfer books shall be closed for a stated period but not longer than
20 days.

       (b)    If Record Date Not Fixed. If no record date is fixed and the Share
transfer books are not closed for the determination of Shareholders, the record
date for the determination of Shareholders entitled to receive a payment of a
dividend or an allotment of any other rights shall be the close of business on
the day on which the resolution of the Board, declaring the dividend or
allotment of rights, is adopted.

       (c)    Record Dates for Adjourned Meetings. When a determination of
Shareholders entitled to vote at any meeting of Shareholders has been made as
provided in the Declaration of

                                       15

<PAGE>

Trust, such determination shall apply to any adjournment thereof, except when
the meeting is adjourned to a date more than 120 days after the record date
fixed for the original meeting, in which case a new record date shall be
determined as set forth in the Declaration of Trust.

       (d)    Share Transfers After Record Date. Except where the Board fixes a
new record date for any adjourned meeting as provided above, any Shareholder who
was a Shareholder on the original record date shall be entitled to receive
notice of and to vote at a meeting of Shareholders or any adjournment thereof
and to receive a dividend or allotment of rights even though he or she has since
such date disposed of his or her Shares, and no Shareholder becoming a
Shareholder after such date shall be entitled to receive notice of or to vote at
such meeting or any adjournment thereof or to receive such dividend or allotment
of rights.

       Section 5.    Share Ledger. The Trust shall maintain at its principal
office or at the office of its counsel, accountants or transfer agent, an
original or duplicate Share ledger containing the name and address of each
Shareholder and the number of Shares of each class held by such Shareholder. The
Trust shall be entitled to treat the holder of record of any Share as the holder
in fact thereof and, accordingly, shall not be bound to recognize any equitable
or other claim to or interest in such Share or on the part of any other person,
whether or not it shall have express or other notice thereof, except as
otherwise provided by the laws of the State of Maryland.

       Section 6.    Fractional Shares; Issuance of Units. The Board may issue
fractional Shares or provide for the issuance of scrip, all on such terms and
under such conditions as they may determine. Notwithstanding any other provision
of the Declaration of Trust or these Bylaws to the contrary, the Board may issue
units consisting of different securities of the Trust. Any security issued in a
unit shall have the same characteristics as any identical securities issued by
the Trust, except that the Board may provide that, for a specified period,
securities of the Trust issued in such unit may be transferred on the books of
the Trust only in such unit.

           ARTICLE VIII. EXEMPTION FROM CONTROL SHARE ACQUISITION ACT

       The provisions of Title 3, Subtitle 7 of the Maryland General Corporation
Law (the Maryland Control Share Acquisition Act), or any successor statute,
shall not apply to any acquisition by any person of Shares of the Trust. This
section may be repealed, in whole or in part, at any time, whether before or
after an acquisition of control shares and, upon such repeal, may, to the extent
provided by any successor bylaw and consistent with applicable law, apply to any
prior or subsequent control share acquisition.

                              ARTICLE IX. AMENDMENT

       These Bylaws may be altered, amended or repealed, and new Bylaws may be
adopted, at any meeting of the Board by vote of a majority of the Trustees,
subject to repeal or change by action of the Shareholders of the Trust entitled
to vote thereon.

                                 ARTICLE X. SEAL

       Section 1.    Seal. The Board may adopt a suitable seal, bearing the name
of the Trust, which shall be in the charge of the Secretary. The Board may
authorize one or more duplicate seals and provide for the custody thereof.

       Section 2.    Affixing Seal. Whenever the Trust is permitted or required
to affix its seal to a document, it shall be sufficient to meet the requirements
of any law, rule or regulation relating to a seal to place the word "(SEAL)"
adjacent to the signature of the person authorized to execute the document on
behalf of the Trust.

               (a) The Trust shall initially be authorized to issue 450,000,000
shares of beneficial interest (par value $0.01 per share), which shall be
designated as units ("Units"). Ownership of Units may be evidenced by
certificates in such form as shall be determined by the Trustees from time to
time in accordance with Maryland law. The certificates shall be negotiable and
title thereto shall be transferred by assignment or delivery in all respects as
a stock certificate of a Maryland corporation. The owners of the Units, who are
the beneficiaries of the Trust, shall be designated as "Unitholders". The Units
shall consist of such types or classes as the Trustees may create and authorize
from time to time and designate as representing a beneficial interest in the
Trust.

               (b) The Trustees may amend this Declaration of Trust, without
Unitholder consent, to increase or decrease the aggregate number of Units or the
number of Units of any class which the Trust has authority to issue.

               (c) The Trustees may (by filing articles supplementary pursuant
to Maryland law) classify or reclassify any unissued Units from time to time by
setting or changing the preferences, conversion or other rights, voting powers,
restrictions, limitations as to dividends or distributions, qualifications or
terms or conditions of redemption of the Units. The Trustees are authorized to
issue from the authorized but unissued Units of the Trust preferred Units in
series and to establish from time to time the number of preferred Units to be
included in each such series and to fix the designation and any preferences,
conversion and other rights, voting powers, restrictions, limitations as to
dividends, qualifications and terms and conditions of redemption of the Units of
each series. Except for Units so classified or reclassified and any preferred
Units issued hereunder, all other Units shall be designated as Common Units.

               All Units issued by the Trust, whether created herein or pursuant
to reclassification or pursuant to subsequent amendments to this Declaration of
Trust shall be subject to the preferences, conversion and other rights, voting
powers, restrictions, limitations as to dividends and terms and conditions of
redemption as set forth in Annex A hereto, as from time

                                       3

to time amended in compliance with Article 6 hereof and Article 12 of Annex A
hereto and as made a part of this Declaration of Trust.

     SECTION 2. Class A Common Units. The Trustee has classified 100,000,000

200,000,000 Units of the Trust as Class A-2 Common Units (the "Class A-2 Common
Units", and, together with the Class A-1 Common Units, the "Class A Common
Units"). Except as expressly provided in this Declaration of Trust, each Class
A-2 Common Unit shall have the same designations, preferences, rights, powers
and duties as each Class A-1 Common Unit. The Trust may issue Class A-2 Common
Units only to Trustee Related Parties. Any Class A-1 Common Units transferred to
a Trustee Related Party in accordance with the provisions of Article 9 of Annex
A hereto shall automatically convert into Class A-2 Common Units upon any such
transfer and the number of authorized Class A-2 Common Units shall automatically
increase in a corresponding amount and the Class A-1 Common Units so converted
being returned to the status of authorized but unissued Class A-1 Common Units.
Any Class A-2 Common Units transferred to any Person other than a Trustee
Related Party in accordance with the provisions of Article 9 of Annex A hereto
shall automatically convert into Class A-1 Common Units upon any such transfer
in accordance with Section 2.1.B of Annex A hereto and the number of authorized
Class A-1 Common Units shall automatically increase in a corresponding amount,
and the Class A-2 Common Units so converted shall be returned to the status of
authorized but unissued Class A-2 Common Units. The Class A-1 Common Units and
the Class A-2 Common Units are referred to in Annex A as Class A-1 Units and
Class A-2 Units, respectively, and collectively as Class A Units.

the Trust as Class B Common Units (the "Class B Common Units"). Except as
otherwise provided in Sections 2.2.D. and 3.1.C. of Annex A hereto, each Class B
Common Unit shall have the same designations, preferences, rights, powers and
duties as each Class A-1 Common Unit. Each Class B Common Unit shall
automatically convert into a Class A Common Unit as provided in Annex A. Upon
any such conversion, the number of authorized Class A Common Units shall
automatically be increased in a corresponding amount, and the number of Class B
Common Units so converted shall be returned to the status of authorized but
unissued Class B Common Units.

SECTION 17. [reserved]

SECTION 18. [reserved]

SECTION 19. [reserved]

SECTION 20. General Nature. All Units shall be personal property entitling the
Unitholders only to those rights provided in this Declaration of Trust,
including Annex A hereto in its entirety or in any articles supplementary
creating any class or series of Units. The legal ownership of the property of
the Trust and the right to conduct the business of the Trust is vested
exclusively in the Trustees; the Unitholders shall have no interest therein
other than the beneficial interest in the Trust conferred by their Units and
shall have no right to compel any partition, division, dividend or distribution
of the Trust or any of its property. The death or incapacity of a Unitholder
shall not terminate the Trust or give his or her legal representative any rights
against other Unitholders, the Trustees or the Trust property, except the rights
described in Article 9 of Annex A hereto.

SECTION 21. Transferability; Transfer Restrictions. Units in the Trust shall be
transferable only in accordance with the provisions of Article 9 of Annex A
hereto. By accepting the transfer of Units, whether of record or beneficially,
all future Unitholders agree to be bound by the provisions of Annex A hereto as
fully as if such Unitholders had executed a stockholders agreement containing
all of such provisions. All certificates representing any class or series of
Units shall bear an appropriate restrictive legend with a statement to the
effect that any transferee agrees to be so bound. The Trust may condition the
transfer and recordation of any change in record ownership by the execution by
any purported Unitholder of any instrument in which the holder agrees to all of
such provisions.

SECTION 22. Preemptive Rights. Except to the extent expressly granted in Section
2.3 of Annex A hereto or in any articles supplementary (which shall be effective
only for the class of Units established thereby), no person shall have any
preemptive, preferential or other similar rights with respect to (i) additional
Capital Contributions or loans to the Trust; or (ii) issuance or sale of any
Units or other Trust Interests.

                                   Unitholders

Section 1. Meetings.

           (a) There shall be an annual meeting of Unitholders at such time and
place, either within or without the State of Maryland, as the Trustees shall
prescribe, at which Trustees shall be elected or re-elected and any other proper
business may be conducted. The annual meeting of Unitholders shall be held upon
reasonable notice at a convenient location and within a reasonable period
following delivery of the annual report. Failure to hold an annual meeting does
not invalidate the Trust's existence or affect any otherwise valid acts of the
Trust. Special meetings of Unitholders may be called by a majority of the
Trustees or by the Chairman of the Board, President or Chief Financial Officer
of the Trust, and shall be called upon the written request of Unitholders
holding in the aggregate twenty-five percent (25%) or more of the outstanding
Units of the Trust entitled to vote. Written or printed notice stating the
place, date and time of the Unitholders' meeting and, in the case of a special
meeting, the purpose or purposes for which the meeting is called, shall be
delivered not less than 10 nor more than 60 days before the day of the meeting
either personally or by mail, by or at the direction of the Trustee or any
officer or the person calling the meeting, to each Unitholder of record entitled
to vote at such meeting. No Unitholder not entitled to vote at a meeting shall
have any rights to notice of a meeting except as expressly provided for in this
Declaration of Trust or under law. No other business than that which is stated
in the call for a special meeting shall be considered at such meeting.

           (b) A majority of the outstanding Units entitled to vote at any
meeting, taken together as a single class, represented in person or by proxy
shall constitute a quorum at such meeting. Whenever any action is to be taken by
the Unitholders, it shall, except as otherwise required by law or this
Declaration of Trust or the Bylaws, be authorized by a majority of the number of
votes entitled to be cast on the matter. Any action required or permitted to be
taken by the holders of the Class A-2 Common Units may be taken without a
meeting by the unanimous written consent of the holders of the Class A-2 Common
Units. The Bylaws of the Trust may provide that any action required or permitted
to be taken by the holders of any other class or series of Units may be taken
without a meeting by the written consent of Unitholders entitled to cast a
sufficient number of votes to approve the matter as required by applicable law,
the Declaration of Trust (including Annex A) or the Bylaws.

Section 2. Voting. At each meeting of Unitholders, each Unitholder entitled to
vote shall have the right to vote, in person or by proxy, the number of Units of
the Trust owned by him or her on each matter on which the vote of the
Unitholders is taken. Only Class A-2 Common Unitholders shall have the right to
vote in the election of Trustees. In any election of Trustees in which more than
one vacancy is to be filled, each Unitholder may vote the number of Class A-2
Common Units of the Trust owned by him or her for each vacancy to be filled.
There shall be no right of cumulative voting. Exclusive voting power is vested
in the Class A-1 Common Units and Class A-2 Common Units, except to the extent
that the Declaration of Trust or Maryland law provides voting rights to any
other class of Units. Each outstanding Unit, regardless of class, shall be
entitled to one vote on each matter submitted to a vote at a meeting of
Unitholders, except (i) to the

                                       7

<PAGE>

extent that this Declaration of Trust, including Annex A hereto in its entirety,
or any articles supplementary limit or deny voting rights to the holders of the
Units of any class or series or (ii) as otherwise provided by Maryland law.

Section 3. Distributions. The Trustees may from time to time authorize the Trust
to pay to Unitholders such dividends or distributions in cash, property or other
assets of the Trust or in securities of the Trust or from any other source as
the Trustees in their discretion shall determine. The Unitholders shall be
entitled to receive dividends and distributions as set forth in Article 3 of
Annex A hereto, when, as and if declared by the Trustees, out of funds legally
available therefor, and to such distributions upon liquidation of the Trust as
set forth in Article 13 of Annex A hereto. The Trustees shall endeavor to
authorize the Trust to pay such dividends and distributions as shall be
necessary pursuant to Article 3 of Annex A hereto and as shall be necessary for
the Parent REIT to qualify as a REIT (so long as the Parent REIT determines to
qualify as a REIT); however, Unitholders shall have no right to any dividend or
distribution unless and until declared by the Trustees. The exercise of the
powers and rights of the Trustees pursuant to this Section 3 shall be subject to
the provisions of any class or series of Units at the time outstanding. The
receipt by any Person in whose name any Units are registered on the records of
the Trust or by his or her duly authorized agent shall be a sufficient discharge
for all dividends or distributions payable or deliverable in respect of such
Units and from all liability with respect to the application thereof.

Section 4. Annual Report. The Trust shall prepare an annual report concerning
its operations for the preceding fiscal year in the manner and within the time
prescribed by the Act.

Section 5. Inspection Rights. Each Unitholder shall have such inspection rights
as set forth in Section 6.5 of Annex A hereto.

Section 6. Limitation of Liability. Unitholders shall not be personally or
individually liable in any manner whatsoever for any debt, act, omission or
obligation incurred by the Trust or the Trustees and shall be under no
obligation to the Trust or its creditors with respect to their Units other than
the obligation to pay to the Trust the full amount of the consideration for
which the Units were issued or to be issued, and except as set forth in Sections
2.2, 5.5, 8.5 and 11.3 of Annex A hereto. The Trust shall indemnify each
Unitholder as set forth in Section 5.7 of Annex A hereto.

                                    ARTICLE 4
                                  The Trustees

Section 1. Number, Qualification, Compensation and Term.

           (a) The number of Trustees shall be not less than one nor more than
fifteen (15) Trustees. The current number of Trustees is one (1), which may be
changed from time to time by resolution of the Trustees. Any action by the
Trustees referred to in Annex A hereto shall include action approved by a
majority of the Trustees at any time there exists more than one Trustee.
Trustees may be any persons, including individuals, corporations, business
trusts, estates, trusts, partnerships, limited partnerships, limited liability
companies, associations, two or more persons having a joint or common interest,
or any other legal or commercial entity. Whenever a vacancy

                                       8

<PAGE>

shall occur, until such vacancy is filled as provided in Section 3 of this
Article 4, the Trustee or Trustees continuing in office, regardless of their
number, shall have all of the powers granted to the Trustees and shall discharge
all of the duties imposed on the Trustees by this Declaration of Trust.

           (b) The term of office of each Trustee shall be one year and until
its successor is elected and qualifies, subject to prior death, resignation or
removal. In the event that the number of Trustees is increased to more than one
(1) the Board of Trustees shall be divided into three classes of Trustees,
designated Class I, Class II and Class III. Each class shall consist, as nearly
as may be possible, of one-third of the total number of Trustees constituting
the entire Board of Trustees. The term of office of each Trustee shall be three
(3) years and until his, her or its successor is elected and qualifies, subject
to prior death, resignation or removal. At each annual meeting of Unitholders,
successors to the class of Trustees whose term expires at such annual meeting
shall be elected. If the authorized number of Trustees constituting the Board of
Trustees is changed, any increase or decrease shall be apportioned among the
classes so as to maintain the number of Trustees in each class as nearly equal
as possible, and any additional Trustee of any class elected to fill a vacancy
resulting from an increase in such class shall hold office until the next annual
meeting of shareholders, but in no case shall a decrease in the number of
Trustees constituting the Board of Trustees shorten the term of any incumbent
Trustee. The name of the current Trustee is as follows:

NAME                                        ADDRESS
----                                        -------

Archstone-Smith Trust                       7670 South Chester Street, Suite 100
                                            Englewood, Colorado 80112

The records of the Trust shall be revised to reflect the names and addresses of
the current Trustees, at such times as any change has occurred.

Section 2. Resignation, Removal and Death. A Trustee may resign at any time by
giving written notice thereof in recordable form to the Trust and to the other
Trustees, if any, at the principal office of the Trust. Any such resignation of
a Trustee shall become effective as provided therein. A Trustee may be removed
only upon the vote of holders of Class A-2 Common Units in accordance with
Section 5.1 of Annex A hereto. Upon the resignation or removal of any Trustee,
such Trustee shall execute and deliver such documents and render such accounting
as the remaining Trustees shall require and shall thereupon be discharged as
Trustee. Upon the incapacity or death of any Trustee, his or her status as a
Trustee shall immediately terminate and his or her legal representatives shall
perform the acts set forth in the preceding sentence.

Section 3. Vacancies. The resignation, removal, incompetency or death of any or
all of the Trustees shall not terminate the Trust or affect its continuity.
Whenever there shall be a vacancy or vacancies among the Trustees (including
vacancies resulting from an increase in the number of Trustees), such vacancy or
vacancies shall be filled (i) at a special meeting of Class A-2 Common
Unitholders called for such purpose (which may be by written consent in lieu of
a meeting), (ii) by the Trustee or Trustees then in office or (iii) at the next
annual meeting of Unitholders. Trustees elected at special meetings of Class A-2
Common Unitholders to fill vacancies shall hold office for

                                       9

<PAGE>

the balance of the unexpired term of the Trustees whom they are replacing or
whose vacancy they are filling (or in the case of a vacancy created by an
increase in the number of Trustees, for the balance of the unexpired term of
Trustees of the same class of Trustees). Any trustee appointed by the remaining
Trustee or Trustees to fill vacancies shall hold office until the next annual
meeting of Unitholders and until his or her successor is elected and qualifies.

Section 4. Successor Trustees. The right, title and interest of the Trustees in
and to the Trust property shall vest automatically in all persons who may
hereafter become trustees upon their due election and qualification without any
further act, and thereupon they shall have the same rights, privileges, powers,
duties and immunities as though named as Trustees in this Declaration of Trust.
Appropriate written evidence of the election and qualification of successor
Trustees shall be filed with the records of the Trust and in such other offices
or places as the Trustee may deem necessary, appropriate or desirable. Upon the
resignation, removal or death of a Trustee, such Trustee (and upon his or her
death, his or her estate) shall automatically cease to have any right, title or
interest in or to any of the Trust property, and the right, title and interest
of such Trustee in and to the Trust property shall vest automatically in the
remaining Trustee or Trustees without any further act.

Section 5. Meetings and Action Without a Meeting. The Trustees may act with or
without a meeting. Except as otherwise provided herein, any action of a majority
of Trustees present at a duly convened meeting of the Trustees shall be
conclusive and binding as an action of the Trustees. Action may be taken without
a meeting in any manner and by any means permitted by Maryland law only by
unanimous consent of all of the Trustees in office and shall be evidenced by a
written certificate or instrument signed by all of the Trustees in office. Any
action taken by the Trustees in accordance with the provisions of this Section 5
and Article 5 of Annex A hereto shall be conclusive and binding on the Trust,
the Trustees and the Unitholders, as an action of all of the Trustees,
collectively, and of the Trust. Any deed, mortgage, evidence of indebtedness or
other instrument, agreement or document of any character, whether similar or
dissimilar, executed by one or more of the Trustees, when authorized at a
meeting or by written authorization without a meeting in accordance with the
provisions of this Section 5, shall be valid and binding on the Trustees, the
Trust and the Unitholders.

Section 6. Authority. The Trustees may hold the legal title to all property
belonging to the Trust. The Trustees shall have absolute and exclusive control,
management and disposition thereof, and absolute and exclusive control over the
management and conduct of the business affairs of the Trust, free from any power
or control on the part of the Unitholders, in the same manner as if the Trustees
were the absolute owners thereof, subject only to the express limitations in
this Declaration of Trust.

Section 7. Powers. The Trustees shall have all of the powers necessary,
convenient or appropriate to effectuate the purposes of the Trust and may take
any action which they deem necessary or desirable and proper to carry out such
purposes. Any determination of the purposes of the Trust made by the Trustees in
good faith shall be conclusive. In construing the provisions of this Declaration
of Trust, the presumption shall be in favor of the grant of powers to the
Trustees. Without limiting the generality of the foregoing, the powers of the
Trustees on behalf of the Trust

                                       10

<PAGE>

shall include those set forth in Section 5.1 of Annex A hereto, subject to the
limitations set forth in Annex A hereto.

Section 8.  Right to Own Units. A Trustee may acquire, hold and dispose of Units
in the Trust for its individual account and may exercise all rights of a
Unitholder to the same extent and in the same manner as if it were not a
Trustee.

Section 9.  [reserved]

Section 10. Limitation of Liability. To the maximum extent that Maryland law in
effect from time to time permits limitation of the liability of trustees of a
real estate investment trust, no Trustee of the Trust shall be liable to the
Trust or to any Unitholder for money damages, except to the extent set forth in
Section 5.8 or other Sections of Annex A hereto.

Section 11. Indemnification. The Trust shall indemnify each Trustee, to the
fullest extent permitted by Maryland law, as amended from time to time, subject
to and in accordance with the provisions of Section 5.7 of Annex A hereto.

Section 12. Persons Dealing with Trustees. No corporation, persons, transfer
agent or other party shall be required to examine or investigate the terms or
conditions contained in this Declaration of Trust or otherwise applicable to the
Trust, and every such corporation, person, transfer agent or other party may
deal with trust property and assets as if the Trustees were the sole and
exclusive owners thereof free of all trusts; and no such corporation, person,
transfer agent or other party dealing with the Trustees or with the Trust or
Trust property and assets shall be required to see to the application of any
money or property paid or delivered to any Trustee, or nominee, agent or
representative of the Trust or the Trustees. A certificate executed by or on
behalf of the Trustees or by any other duly authorized representative of the
Trust delivered to any person or party dealing with the Trust or Trust property
and assets, or, if relating to real property, recorded in the deed records for
the county or district in which such real property lies, certifying as to the
identity and authority of the Trustees, agents or representatives of the Trust
for the time being, or as to any action of the Trustees or of the Trust, or of
the Unitholders, or as to any other fact affecting or relating to the Trust or
this Declaration of Trust, may be treated as conclusive evidence thereof by all
persons dealing with the Trust. No provision of this Declaration of Trust shall
diminish or affect the obligation of the Trustees and every other representative
or agent of the Trust to deal fairly and act in good faith with respect to the
Trust and the Unitholders insofar as the relationship and accounting among the
parties to the Trust is concerned; but no third party dealing with the Trust or
with any Trustee, agent or representative of the Trust shall be obliged or
required to inquire into, investigate or be responsible for the discharge and
performance of such obligation.

Section 13. Administrative Powers. The Trustees shall have the power to pay the
expenses of administration of the Trust, including all legal and other expenses
in connection with the preparation and carrying out of the acquisition of
properties and the issuance of Units; and to employ such officers, experts,
counsel, managers, salesmen, agents, workmen, clerks and other persons as they
deem appropriate. The Trustees shall also enjoy the full benefit of the
provisions of Section 5.9 of Annex A hereto.

                                       11

Section 14. Election of Officers. The Trustees shall annually elect a President
and a Secretary of the Trust. The Trustees may also annually elect one or more
Vice Presidents, a Treasurer, Assistant Secretaries, Assistant Treasurers and
such other officers as the Trustees shall deem proper. Except as required by
law, the officers of the Trust need not be Trustees. All officers and agents of
the Trust shall have such authority and perform such duties in the management of
the Trust as may be provided in the Bylaws or as may be determined by the
Trustees not inconsistent with the Bylaws. Any officer or agent elected or
appointed by the Trustees may be removed by the Trustees whenever in its
judgment the best interest of the Trust will be served thereby, but such removal
shall be without prejudice to the contract rights, if any, of the person so
removed. Election or appointment of any officer or agent shall not of itself
create contract rights. The Trustees shall fix the compensation of all officers.

Section 15. Committees and Delegation of Powers and Duties. The Trustees may, in
their discretion, by resolution passed by a majority of the Trustees, designate
from among the Trustees one or more committees which shall consist of one or
more Trustees. The Trustees may designate one or more Trustees as alternate
members of any such committee, who may replace any absent or disqualified member
at any meeting of the committee. Such committees shall have and may exercise
such powers as shall be conferred or authorized by the resolution appointing
them (including, but not limited to, the determination of the type and amount of
consideration at which Units are to be issued). A majority of any such committee
may determine its action and fix the time and place of its meetings, unless the
Trustees shall otherwise provide. The Trustees, by resolution passed by a
majority of the Trustees, may at any time change the membership of any
committee, fill vacancies on it or dissolve it. The Bylaws, or a majority of the
Trustees, may authorize any one or more of the Trustees, or any one or more of
the officers or employees or agents of the Trust, on behalf of the Trust, to
exercise and perform any and all powers granted to the Trustees, and to
discharge any and all duties imposed on the Trustees, and to do any acts and to
execute any instruments deemed by such person or persons to be necessary or
appropriate to exercise such power or to discharge such duties, and to exercise

                                    ARTICLE 8
      Limitation of Liability and Indemnification of Officers and Employers

Section 1. Limitation of Liability of Officers and Employees. To the maximum
extent that Maryland law in effect from time to time permits limitation of the
liability of officers, employees or agents of a real estate investment trust, no
officer, employee or agent of the Trust shall be liable to the Trust or to any
Unitholder for money damages.

Section 2. Indemnification of Officers and Employees. The Trust shall indemnify
each officer, employee and agent, to the fullest extent permitted by Maryland
law, as amended from time to time, subject to and in accordance with the
provisions of Section 5.7 of Annex A hereto.

Section 3. Insurance. Notwithstanding any other provisions of this Declaration
of Trust, the Trust, for purposes of providing indemnification for its Trustees,
officers, employees and agents, shall have the authority, without specific
Unitholder approval, to enter into insurance or other arrangements, with persons
or entities which are regularly engaged in the business of providing insurance
coverage, to indemnify all Trustees, officers, employees and agents of the Trust
against any and all liabilities and expenses incurred by them by reason of their
being Trustees, officers, employees or agents of the Trust, whether or not the
Trust would otherwise have the power under this Declaration of Trust or under
Maryland law to indemnify such persons against such liability. Without limiting
the power of the Trust to procure or maintain any kind of insurance or other
arrangement, the Trust may, for the benefit of persons indemnified by it, (i)
create a trust fund, (ii) establish any form of self-insurance, (iii) secure its
indemnity obligation by grant of any security interest or other lien on the
assets of the Trust or (iv) establish a letter of credit, guaranty or surety
arrangement. Any such insurance or other arrangement may be procured, maintained
or established within the Trust or with any insurer or other person deemed
appropriate by the trustees regardless of whether all or part of the stock or
other securities thereof are owned in whole or in part by the Trust. In the
absence of fraud, the judgment of the Trustees as to the terms and conditions of
insurance or other arrangement and the identity of the insurer or other
arrangement shall not be subject to voidability, nor subject the Trustees
approving such insurance or other arrangement to liability, on any ground,
regardless of whether Trustees participating in and approving such insurance or
other arrangement shall be beneficiaries thereof.

                                     ANNEX A

          This Annex A constitutes not only an integral part of the Declaration
               -------
of Trust but also a separate agreement among all of the holders of Units (as
defined herein) of the Trust, each of whom is identified on the books and
records of the Trust. Each holder of Units on the Effective Date (as defined
herein) shall become a party to this agreement without further action required
on the part of any such holder.

          Effective as of the day prior to the Effective Date, the Trust elected
pursuant to Treasury Regulation (S) 301.7701-3(c) to be treated for federal
income tax purposes as a disregarded entity not separate from its owner (and not
as an "association taxable as a corporation"). On the Effective Date, this
election has caused the Trust to become treated as a "partnership" for federal
income tax purposes. The provisions in this Annex A relating to Capital Accounts
                                            -------
(as defined herein) and allocations of Net Income and Net Loss (each as defined
herein) (and items of income, gain, loss, and deduction) for federal income tax
purposes are intended to be consistent with the provisions of the Code (as
defined herein) and the Treasury Regulations (as defined herein) applicable to
entities that are characterized as "partnerships" for federal income tax
purposes.

                                    ARTICLE 1

                                  DEFINED TERMS

               The following definitions shall be for all purposes, unless
otherwise clearly indicated to the contrary, applied to the terms used in this
Agreement.

               "Act" means Title 8 of the Corporations and Associations Article
                ---

restore pursuant to the penultimate sentences of Regulations Sections
1.704-2(g)(1) and 1.704-2(i)(5) and (ii) decreased by the items described in
Regulations Sections 1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5), and
1.704-1(b)(2)(ii)(d)(6). The foregoing definition of Adjusted Capital Account is
intended to comply with the provisions of Regulations Section

           ---------
or indirectly controlling, controlled by or under common control with such
Person, (ii) any Person owning or controlling ten percent (10%) or more of the

purchaser in an arms' length transaction where neither the purchaser nor the
seller were under economic compulsion to enter into the transaction (without
regard to any discount in value as a result of the Trust's minority interest in
any property or any illiquidity of the Trust's interest in any property).

rights, all such that the economic interests are substantially the same as those
of the New Securities, and (ii) the Trustee contributes the net proceeds from
the grant, award or issuance of such New Securities and from the exercise of
rights contained in such New Securities to the Trust. Without limiting the
foregoing, the Trustee is expressly authorized to issue New Securities for less
than fair market value, and to cause the Trust to issue to the Trustee
corresponding Trust Interests, so long as (x) the Trustee concludes in good
faith that such issuance is in the interests of the Trustee and the Trust (for
example, and not by way of limitation, the issuance of Shares and corresponding
Units pursuant to an employee share purchase plan providing for employee
purchases of Shares at a discount from fair market value or employee share
options that have an exercise price that is less than the fair market value of
the Shares, either at the time of issuance or at the time of exercise), and (y)

               A-1 Unit on the day immediately following the Trust Record Date
               for the Distribution Period in which the Class B Unit was issued,
               without the requirement for any action by either the Trust or the
               Unitholder holding the Class B Unit.

          (3)  A holder of Class B Units will not have the Redemption Right
               under Section 6.6 with respect to its Class B Units.

          (4)  The Trustee shall cause Class B Units to be issued by the Trust
               only pursuant to an amendment to this Agreement pursuant to
               Section 12.2.B hereof, which amendment shall designate that the
               newly issued Units are Class B Units. The Trustee shall have the
               right, in its sole and absolute discretion, subject to Section
               2.2.A and Section 3.1.E hereof, to determine whether the Trust

          D. Certain Restrictions on Issuances of Units or Other Trust
             ---------------------------------------------------------
Interests. Notwithstanding the foregoing, in no event may the Trustee cause the
---------
Trust to issue to Unitholders (including the Trustee and its Affiliates) or
other Persons any Units or other Trust Interests if such issuance would, in the
opinion of counsel to the Trust, cause any portion of the assets of the Trust to
constitute assets of any ERISA Plan Investor pursuant to 29 C.F.R.ss.
2510.3-101, or any successor regulation thereto.

     Section 2.3    Preemptive Rights
                    -----------------

          If the Trustee acquires any Class A-2 Units using the proceeds from
any exercise of any rights (as defined in the definition of "Shares Amount")
issued under a shareholder rights plan (or other arrangement having the same
objective and substantially the same effect), then (a) the holders of Common
Units at such time (other than the Trustee) as a group shall have the right to
acquire, at the same price per Class A-2 Unit paid by the Trustee, a total
number of additional Class A-1 Units equal to the product of (i) the total
number of Common Units held by such holders, multiplied by (ii) a fraction, the
numerator of which is the number of Class A-2 Units issued to the Trustee as a
result of the exercise of such rights and the denominator of which is the total
number of Class A-2 Units held by the Trustee immediately prior to such issuance
(which fraction is referred to as the "Exercise Percentage"), and (b) each
holder of a Class A-1 Unit or Class B Unit at such time shall have the right to
acquire, at the same price per Class A-2 Unit paid by the Trustee, a number of
Class A-1 Units equal to the product of (iii) the aggregate number of Common
Units that such holder holds at such time, multiplied by (iv) the Exercise
Percentage. (Thus, for example, if the Trustee were to acquire 2,000,000 Class
A-2 Units at $5 per Unit from the proceeds of the exercise of outstanding rights
issued under a stockholder rights plan at a time when the Trustee already owned
8,000,000 Class A-2 Units out of a total of 12,000,000 outstanding Common Units
(which would represent a 25% increase in the number of Class A-2 Units held by
the Trustee), then the other holders of Common Units as a group would have the
right to purchase a total of 1,000,000 Class A-1 Units at $5 per Class A-1 Unit,
and each holder of a Class A-1 Unit or Class B Unit would be entitled to
purchase his proportionate share of such Class A-1 Units, or .25 Class A-1 Units
for each Class A Unit or Class B Unit then held by such holder.) In the event
Units or Trust Interests other than Class A-2 Units are issued to the Trustee
using proceeds of any exercise of rights issued under a stockholder rights plan
(or other arrangement), the holders of Common Units shall be granted the right
to acquire such other Units or Trust Interests at the same price as paid by the
Trustee and in such amounts as would be comparable to their rights had Class A-1
Units been issued instead. The Trustee shall provide prompt written notice to
the holders of Common Units of its acquisition of Class A-2 Units (or other
Units or Trust Interests) using such proceeds and shall establish in good faith
such procedures as it deems appropriate (including, without limitation,
procedures to eliminate the issuance of fractional Units if the Trustee deems
appropriate) to effectuate the rights of the holders of Common Units under the
preceding provisions of this Section 2.3. Except to the extent expressly granted
by the Trust pursuant to this Section 2.3 or another agreement, no person shall
have any preemptive, preferential or other similar right with respect to (i)
additional Capital Contributions or loans to the Trust; or (ii) issuance or sale
of any Units or other Trust Interests.

     Section 2.4   Other Contribution Provisions
                   -----------------------------

          A.   If any Person becomes a Unitholder and is given a Capital Account
in exchange for services rendered to the Trust, such transaction shall be
treated by the Trust and the affected Unitholder as if the Trust had compensated
such Unitholder in cash, and the Unitholder had contributed such cash to the
capital of the Trust.

          B.   To the extent the Trust acquires any property (or an indirect
interest therein) by the merger of any other Person into the Trust or with or
into a Subsidiary of the Trust in a triangular merger, Persons who receive Trust
Interests in exchange for their interests in the Person merging into the Trust
or with or into a Subsidiary of the Trust shall become Unitholders and shall be
deemed to have made Capital Contributions as provided in the applicable merger
agreement (or, if not so provided, as determined by the Trustee in its sole
discretion), and as set forth in the Trust's books and records.

                                  DISTRIBUTIONS

     Section 3.1   Requirement and Characterization of Distributions
                   -------------------------------------------------

          A.   General. The Unitholders shall be entitled to receive
               -------
distributions when, as and if declared by the Trustee, out of funds legally
available therefor. Subject to Section 3.1.F, the Trustee shall cause the Trust
to distribute at least quarterly an amount equal to one hundred percent (100%)
of Available Cash of the Trust during such quarter or shorter period to the
Persons who are holders of Units on the respective Trust Record Dates
established for distribution to the applicable classes with respect to such
quarter or shorter period. The Trustee shall endeavor to cause distributions to
be made in the manner provided in Sections 3.1.B, 3.1.C and 3.1.D and in
accordance with the respective terms established for each other class of Trust
Interests hereafter created. Notwithstanding anything to the contrary contained
herein, in no event may a Unitholder receive a distribution of Available Cash
with respect to a Unit for a quarter or shorter period if such Unitholder is
entitled to receive a distribution with respect to a Share for which such Unit
has been redeemed or exchanged. Unless otherwise expressly provided for herein,
in Exhibits F-T hereto, with respect to Series A Preferred Units, Series B
   ------------
Junior Participating Preferred Units, Series C Preferred Units, Series D
Preferred Units, Series E Preferred Units, Series F Preferred Units, Series G
Preferred Units, Series H Preferred Units, Series I Preferred Units, Series J
Preferred Units, Series K Preferred Units and Series L Preferred Units,
respectively, or in the terms established at the time a new class or series of
Trust Interests is created in accordance with Article 2 hereof, no Trust
Interest shall be entitled to a distribution in preference to any other Trust
Interest. The Trustee shall make such reasonable efforts, as determined by it in
its sole and absolute discretion and consistent with the qualification of the
Parent REIT as a REIT, to distribute Available Cash (a) to the Unitholders other
than the Trustee so as to preclude any such distribution or portion thereof from
being treated as part of a sale of property to the Trust by such Unitholder
under Section 707 of the Code or the Regulations thereunder; provided that, the
                                                             -------- ----
Trustee and the Trust shall not have liability to the Unitholder

                                       18

<PAGE>

under any circumstances as a result of any distribution to such Unitholder being
so treated, and (b) to the Parent REIT in an amount sufficient to enable the
Parent REIT to make distributions to its shareholders that will enable the
Parent REIT to pay shareholder dividends that will (1) satisfy the requirements
for qualification as a REIT under the Code and the Regulations (the "REIT
Requirements") and (2) avoid any federal income or excise tax liability for the
Parent REIT.

          B.   Priority of Distributions. (i) Distributions to Unitholders
               -------------------------
holding a class of Trust Interests that is entitled to any preference in
distribution (including, without limitation, the preferences in distribution set
forth in Exhibits F-T hereto, with respect to Series A Preferred Units, Series B
         ------------
Junior Participating Preferred Units, Series C Preferred Units, Series D
Preferred Units, Series E Preferred Units, Series F Preferred Units, Series G
Preferred Units, Series H Preferred Units, Series I Preferred Units, Series J
Preferred Units, Series K Preferred Units and Series L Preferred Units,
respectively, shall be made in accordance with the rights of such class of Trust
Interests to holders of such Units on the respective Trust Record Date
established for the distribution to such class of Trust Interests (and, within
such class, pro rata in proportion to the respective Percentage Interests in
such class on such Trust Record Date).

               (ii) Distributions to holders of Class A-1 Units, Class A-2
Units, Class B Units and Units of any other class of Trust Interests that are
not entitled to any preference in distribution shall be made quarterly (or more
frequently in the sole and absolute discretion of the Trustee), to the extent
there is Available Cash remaining after the payment of distributions in respect
of any classes of Trust Interests entitled to a preference in distribution in
accordance with the foregoing clause (i), in accordance with the terms of such
class as set forth in this Agreement or otherwise established by the Trustee
pursuant to Section 2.2 to holders of such Units on the respective Trust Record
Date established for the distribution to each such class of Trust Interests
(and, within each such class, pro rata in proportion to the respective
Percentage Interests in such class on such Trust Record Date).

          C.   Distribution When Class B Units Are Outstanding. If for any
               -----------------------------------------------
quarter or shorter period with respect to which a distribution is to be made (a
"Distribution Period") Class B Units are outstanding on the Trust Record Date
for such Distribution Period, the Trustee shall allocate the Available Cash with
respect to such Distribution Period available for distribution with respect to
the Class A-1 Units, Class A-2 Units and Class B Units collectively ("Common
Unit Available Cash") between the Unitholders who are holders of Class A-1 Units
or Class A-2 Units ("Class A") and the Unitholders who are holders of Class B
Units ("Class B") as follows:

          (1)  Class A shall receive that portion of the Common Unit Available
               Cash (the "Class A Cash Portion") determined by multiplying the
               amount of Available Cash by the following fraction:

                                            A x Y
                                            --------
                                        (A x Y)+(B x X)

                                       19

<PAGE>

          (1)  Class B shall receive that portion of the Common Unit Available
               Cash (the "Class B Cash Portion") determined by multiplying the
               amount of Available Cash by the following fraction:

                                          B x X
                                       -------------
                                      (A x Y)+(B x X)

          (1)  For purposes of the foregoing formulas, (i) "A" equals the number
               of Class A-1 Units and Class A-2 Units outstanding on the Trust
               Record Date for such Distribution Period; (ii) "B" equals the
               number of Class B Units outstanding on the Trust Record Date for
               such Distribution Period; (iii) "Y" equals the number of days in
               the Distribution Period; and (iv) "X" equals the number of days
               in the Distribution Period for which the Class B Units were
               issued and outstanding.

          The Class A Cash Portion shall be distributed among Unitholders
holding Class A-1 Units or Class A-2 Units on the Trust Record Date for the
Distribution Period in accordance with the number of Class A-1 Units or Class
A-2 Units held by each Unitholder on such Trust Record Date; provided that in no
event may a Unitholder receive a distribution of Available Cash with respect to
a Class A-1 Unit or Class A-2 Units if a Unitholder is entitled to receive a
distribution out of such Available Cash with respect to a Share for which such
Class A-1 Unit has been redeemed or exchanged. The Class B Cash Portion shall be
distributed among the Unitholders holding Class B Units on the Trust Record Date
for the Distribution Period in accordance with the number of Class B Units held
by each Unitholder on such Trust Record Date. In no event shall any Class B
Units be entitled to receive any distribution of Available Cash for any
Distribution Period ending prior to the date on which such Class B Units are
issued.

          D.   Distributions When Class B Units Have Been Issued on Different
               --------------------------------------------------------------
Dates. In the event that Class B Units which have been issued on different dates
-----
are outstanding on the Trust Record Date for any Distribution Period, then the
Class B Units issued on each particular date shall be treated as a separate
series of Common Units for purposes of making the allocation of Common Unit
Available Cash for such Distribution Period among the holders of Common Units
(and the formula for making such allocation, and the definitions of variables
used therein, shall be modified accordingly). Thus, for example, if two series
of Class B Units are outstanding on the Trust Record Date for any Distribution
Period, the allocation formula for each series, "Series B\\1\\" and "Series
B\\2\\," would be as follows:

          (1)  Series B\\1\\ shall receive that portion of the Common Unit
               Available Cash determined by multiplying the amount of Common
               Unit Available Cash by the following fraction:

                                         B\\1\\ x X\\1\\
                             -----------------------------------------
                            (A x Y)+(B\\1\\ x X\\1\\)+(B\\2\\ x X\\2\\)

                                       20

<PAGE>

          (1)  Series B\\2\\ shall receive that portion of the Common Unit
               Available Cash determined by multiplying the amount of Common
               Unit Available Cash by the following fraction:

                                     B\\2\\ x X\\2\\
                         ----------------------------------------
                        (A x Y)+(B\\1\\ x X\\1\\)+(B\\2\\ x X\\2\\)

          (1)  For purposes of the foregoing formulas the definitions set forth
               in Section 3.1.C.3 remain the same except that (i) "B\\1\\"
               equals the number of Common Units in Series B\\1\\ outstanding on
               the Trust Record Date for such Distribution Period; (ii) "B\\2\\"
               equals the number of Common Units in Series B\\2\\ outstanding on
               the Trust Record Date for such Distribution Period; (iii)
               "X\\1\\" equals the number of days in the Distribution Period for
               which the Units in Series B\\1\\ were issued and outstanding; and
               (iv) "X\\2\\" equals the number of days in the Distribution
               Period for which the Common Units in Series B\\2\\ were issued
               and outstanding.

          (2)  Notwithstanding anything to the contrary contained herein, in no
               event shall a Unitholder receive a distribution of Available Cash
               with respect to any Common Unit with respect to any quarter or
               shorter period until such time as the Trust has distributed to
               the holders of Preferred Units an amount sufficient to pay all
               distributions payable with respect to such Preferred Units
               through the last day of such quarter or shorter period, in
               accordance with the instruments designating such Preferred Units.

          E.   Special Rule if Parent REIT Not Publicly Traded. In addition (and
               -----------------------------------------------
without regard to the amount of Available Cash), if the Shares of
the Parent REIT are not Publicly Traded, the Trustee shall make cash
distributions with respect to the Class A-1 Units and Class A-2 Units at least
annually for each taxable year of the Trust beginning prior to the twentieth
(20th) anniversary of the Effective Date in an aggregate amount with respect to
each such taxable year at least equal to 90% of the Trust's taxable income for
such year allocable to the Class A-1 Units and Class A-2 Units, with such
distributions to be made not later than 60 days after the end of such year.
Notwithstanding any limitations set forth in Section 2.2, the holders of Class
A-2 Units shall have the right to elect, within five (5) Business Days after the
distribution of Available Cash, to reinvest any cash distributed to the holders
of Class A-2 Units pursuant to this Section 3.1.E. in exchange for additional
Class A-2 Units, with the purchase price payable by such holders for each such
Class A-2 Unit being an amount equal to the Value of a Class A-2 Unit at the
time such cash is reinvested and with such purchase price being paid in full in
cash.

          F.   The Trustee shall have the authority to defer the distribution
referred to in Section 3.1E (the "Mandatory Distribution") if, but only if, it
shall determine in good faith after diligent exploration of all commercially
reasonably available alternatives that after giving effect to the Mandatory
Distribution (x) the Trust shall be unable to pay its indebtedness as it becomes

                                       21

<PAGE>

due in the usual course of business, or (y) the Trust's assets will be less than
the sum of its total liabilities and the amount that would be needed to satisfy
all preferential rights of the holders of Preferred Units upon liquidation of
the Trust. In making such determination, the Trustee shall consider the Trust's
most recently available financial statements, prepared on the basis of generally
accepted accounting principles and on fair value principles, and in the event of
conflict, base its determination on the methodology that would yield the more
favorable result to the Unitholders. If the Trustee determines to defer the
Mandatory Distribution, it shall reconsider the authorization of the
distribution at least monthly until made and shall use its commercially
reasonable best efforts to restructure the Trust assets, operations and
indebtedness in a manner that will facilitate the payment of accrued but unpaid
distributions under this Section 3.1.F as promptly as practicable and the
distribution of amounts reasonably expected to accrue hereunder in subsequent
periods.

     Section 3.2   Amounts Withheld
                   ----------------

          All amounts withheld pursuant to the Code or any provisions of any
state or local tax law and Section 8.5 hereof with respect to any allocation,
payment or distribution to the Trustee or the Unitholders other than the Trustee
shall be treated as amounts distributed to the Trustee or Unitholders other than
the Trustee, as the case may be, pursuant to Section 3.1 for all purposes under
this Agreement.

     Section 3.3   Distributions Upon Liquidation
                   ------------------------------

          Proceeds from a Terminating Capital Transaction and any other cash
received or reductions in reserves made after commencement of the liquidation of
the Trust, shall be distributed to the Unitholders in accordance with Section
11.2.

     Section 4.1   Allocations For Capital Account Purposes
                   ----------------------------------------

          For purposes of maintaining the Capital Accounts and in determining
the rights of the Unitholders among themselves, the Trust's items of income,
gain, loss and deduction (computed in accordance with Exhibit A hereof) shall be
                                                      ---------
allocated among the Unitholders in each taxable year (or portion thereof) as
provided herein below.

          A.    Net Income. After giving effect to the special allocations set
                ----------
forth in Section 1 of Exhibit B hereof, Net Income shall be allocated:
                      ---------

          (1) first, to the Trustee to the extent that cumulative Net Losses
              -----
              previously allocated the Trustee pursuant to 4.1.B(6) exceed
              cumulative Net Income previously allocated to the Trustee pursuant
              to this clause (1);

                                       22

<PAGE>

          (2) second, to each Protected Unitholder until the cumulative Net
              ------
              Income allocated such Protected Unitholder under this clause (2)
              equals the cumulative Net Losses allocated such Protected
              Unitholder under Section 4.1.B(5) (and, within the class of
              Protected Unitholders, pro rata in proportion to their respective
              percentages of the cumulative Net Losses allocated all Protected
              Unitholders pursuant to Section 4.1.B(5) hereof);

          (3) third, to the Trustee until the cumulative Net Income allocated
              -----
              under this clause (3) equals the cumulative Net Losses allocated
              the Trustee under Section 4.1.B(4);

          (4) fourth, to the holders of any Trust Interests that are entitled to
              ------
              any preference upon liquidation until the cumulative Net Income
              allocated under this clause (4) equals the cumulative Net Losses
              allocated to such Unitholders under Section 4.1.B(3);

          (5) fifth, to the holders of any Trust Interests that are entitled to
              -----
              any preference in distribution in accordance with the rights of
              any such class of Trust Interests until each such Trust Interests
              have been allocated, on a cumulative basis pursuant to this clause
              (5), Net Income equal to the aggregate amount of distributions
              such holders have been entitled to receive (whether or not such
              holders have actually received such amounts) which are
              attributable to the preference of such class of Trust Interests
              (and, within such class, pro rata in proportion to the respective
              Percentage Interests as of the last day of the period for which
              such allocation is being made); and

          (6) finally, with respect to Trust Interests that are not entitled to
              -------
              any preference in the allocation of Net Income, pro rata to each
              such class in accordance with the terms of such class (and, within
              such class, pro rata in proportion to the respective Percentage
              Interests as of the last day of the period for which such
              allocation is being made).

          B.    Net Losses. After giving effect to the special allocations set
                ----------
forth in Section 1 of Exhibit B, Net Losses shall be allocated:
                      ---------

          (1) first, to the holders of Trust Interests, in proportion to their
              -----
              share of the Net Income previously allocated pursuant to Section
              4.1.A(6), to the extent that any prior allocations of Net Income
              to such Unitholders pursuant to Section 4.1.A(6) exceed, on a
              cumulative basis, distributions with respect to such Trust
              Interests pursuant to clause (ii) of Section 3.1.B;

          (2) second, with respect to classes of Trust Interests that are not
              ------
              entitled to any preference in distribution upon liquidation, pro
              rata to each such class in accordance with the terms of such class

              Percentage Interests as of the last day of the period for which
              such allocation is being made); provided that Net Losses

              shall not be allocated to any Unitholder pursuant to this Section
              4.1.B(2) to the extent that such allocation would cause such

extent permitted in Section 5.5.A; and (iv) the Trust shall not be responsible
for any expenses or liabilities of the Trustee that are excluded from the scope
of the indemnification provisions of Section 5.7.A by reason of the provisions
of clause (i), (ii) or (iii) thereof. The Trustee shall determine in good faith
the amount of expenses incurred by it related to the ownership of Trust
Interests and operation of, or for the benefit of, the Trust. If certain
expenses are incurred that are related both to the ownership of Trust Interests
or operation of, or for the benefit of, the Trust and to the ownership of other
assets (other than Qualified REIT Subsidiaries or limited liability companies as
permitted under Section 5.7.A) or the operation of other businesses, such
expenses will be allocated to the Trust and such other entities (including the
Trustee) owning such other assets or businesses in such a manner as the Trustee
in its sole and absolute discretion deems fair and reasonable. Such
reimbursements shall be in addition to

                                       30

<PAGE>

any reimbursement to the Trustee pursuant to Section 8.3.C and as a result of
indemnification pursuant to Section 5.7. All payments and reimbursements
hereunder shall be characterized for federal income tax purposes as expenses of
the Trust incurred on its behalf, and not as expenses of the Trustee.

          C. Trust Interest Issuance Expenses. The Trustee shall also be
             --------------------------------
reimbursed for all expenses it incurs relating to any issuance of Trust
Interests, Shares, Debt of the Trust or Funding Debt or rights, options,
warrants or convertible or exchangeable securities pursuant to Article 2
(including, without limitation, all costs, expenses, damages and other payments
resulting from or arising in connection with litigation related to any of the
foregoing), all of which expenses are considered by the Unitholders to
constitute expenses of, and for the benefit of, the Trust.

          D. Purchases of Shares by the Trustee. If the Parent REIT exercises
             ----------------------------------
its rights under the Trustee Declaration of Trust to purchase Shares or
otherwise elects to purchase from its shareholders Shares in connection with a
share repurchase or similar program or for the purpose of delivering such Shares
to satisfy an obligation under any dividend reinvestment or equity purchase
program adopted by the Parent REIT, any employee equity purchase plan adopted by
the Parent REIT or any similar obligation or arrangement undertaken by the
Parent REIT in the future, the purchase price paid by the Parent REIT for those
Shares and any other expenses incurred by the Parent REIT in connection with
such purchase shall be considered expenses of the Trust and shall be
reimbursable to the Parent REIT, subject to the conditions that: (i) if those
Shares subsequently are to be sold by the Parent REIT, the Parent REIT shall pay
to the Trust any proceeds received by the Parent REIT for those Shares (provided
                                                                        --------
that a transfer of Shares for Units pursuant to Section 6.6 would not be
considered a sale for such purposes); and (ii) if such Shares are not
retransferred by the Parent REIT within thirty (30) days after the purchase
thereof, the Parent REIT shall cause the Trust to cancel a number of Units
(rounded to the nearest whole Unit) held by the Parent REIT equal to (x) in the
case of Common Shares, the product attained by multiplying the number of those
Shares by a fraction, the numerator of which is one and the denominator of which
is the Conversion Factor, and (y) in the case of any other Shares, the number of
such Shares, which Units shall be treated as having been redeemed by the Trust
for the payment made by the Trust to the Parent REIT with respect to the
corresponding Shares.

          E. Reimbursement Not a Distribution. If and to the extent any
             --------------------------------
reimbursement made pursuant to this Section 5.4 is determined for federal income
tax purposes not to constitute a payment of expenses of the Trust, the amount so
determined shall constitute a guaranteed payment with respect to capital within
the meaning of Section 707(c) of the Code, shall be treated consistently
therewith by the Trust and all Unitholders and shall not be treated as a
distribution for purposes of computing the Unitholders' Capital Accounts.

          F. Funding Acquisitions. In the event that the Trustee shall undertake
             --------------------
to acquire (whether by merger, purchase, or otherwise) the assets or equity
interests of another Person and such acquisition shall require the payment of
cash by the Trustee (whether to such Person or to any other selling party or
parties in such transaction or to one or more creditors, if any, of such Person
or such selling party or parties), (i) the Trust shall advance to the Trustee
the cash required to consummate such acquisition if, and to the extent that,
such cash is not to be

                                       31

<PAGE>

obtained by the Trustee through an issuance of Shares described in Section 2.2,
(ii) the Trustee shall immediately, upon consummation of such acquisition,
transfer to the Trust (or cause to be transferred to the Trust), in full and
complete satisfaction of such advance and as required by Section 5.5, the assets
or equity interests of such Person acquired by the Trustee in such acquisition,
and (iii) pursuant to and in accordance with Section 2.2, the Trust shall issue
to the Trustee Trust Interests and/or rights, options, warrants or convertible
or exchangeable securities of the Trust having designations, preferences and
other rights that are substantially the same as those of any additional Shares,
other equity securities, New Securities and/or Convertible Funding Debt, as the
case may be, issued by the Trustee in connection with such acquisition (whether
issued directly to participants in the acquisition transaction or to third
parties in order to obtain cash to complete the acquisition). In addition to,
and without limiting the foregoing, in the event that the Trustee engages in a
transaction in which (x) the Trustee (or a wholly owned direct or indirect
Subsidiary of the Trustee) merges with another entity (referred to as the
"Parent Entity") that is organized in the "UPREIT format" (i.e., where the
Parent Entity holds substantially all of its assets and conducts substantially
all of its operations through a partnership, limited liability company or other
entity (referred to as an "Operating Entity")) and the Trustee survives such
merger, (y) such Operating Entity merges with or is otherwise acquired by the
Trust in exchange in whole or in part for Trust Interests, and (z) the Trustee
is required or elects to pay part of the consideration in connection with such
merger involving the Parent Entity in the form of cash and part of the
consideration in the form of Shares, the Trust shall distribute to the Trustee
with respect to its existing Trust Interest an amount of cash sufficient to
complete such transaction and the Trustee shall cause the Trust to cancel a
number of Units (rounded to the nearest whole number) held by the Trust equal to
the product attained by multiplying the number of additional Shares of the Trust
that the Trust would have issued to the Parent Entity or the owners of the
Parent Entity in such transaction if the entire consideration therefor were to
have been paid in Shares by a fraction, the numerator of which is one and the
denominator of which is the Conversion Factor.

    Section 5.5  Outside Activities of the Trustee
                 ---------------------------------

          A. General. Without the approval of the holders of at least a majority
             -------
of the Class A-1 Units outstanding and entitled to vote thereon, the Trustee
shall not, directly or indirectly, enter into or conduct any business other than
in connection with the ownership, acquisition and disposition of Trust Interests
as Trustee or Unitholder and the management of the business of the Trust and
such activities as are incidental thereto. Without the approval of the holders
of at least a majority of the Class A-1 Units outstanding and entitled to vote
thereon, the assets of the Parent REIT shall be limited to Trust Interests and
permitted debt obligations of the Trust (as contemplated by Section 5.5.E), so
that Shares and Units are completely fungible except as otherwise specifically
provided herein; provided that the Trustee shall be permitted to hold such bank
                 -------- ----
accounts or similar instruments or accounts in its name as it deems necessary to
carry out its responsibilities and purposes as contemplated under this Agreement
and its organizational documents (provided that accounts held on behalf of the
                                  -------- ----
Trust to permit the Trustee to carry out its responsibilities under this
Agreement shall be considered to belong to the Trust and the interest earned
thereon shall, subject to Section 5.4.B, be applied for the benefit of the
Trust); and, provided further that, the Parent REIT shall be permitted to
             -------- -------
acquire, directly or

                                       32

<PAGE>

through one or more Qualified REIT Subsidiaries or limited liability companies,
Qualified Assets. The Parent REIT and any of its Affiliates may acquire Trust
Interests and shall be entitled to exercise all rights of a Unitholder relating
to such Trust Interests.

          B. Forfeiture of Shares. If the Trust or the Parent REIT acquires
             --------------------
Shares as a result of the forfeiture of such Shares under a restricted share,
share bonus or other similar share plan, then the Trustee shall cause the Trust
to cancel that number of Units equal to the number of Shares so acquired, and,
if the Trust acquired such Shares, it shall transfer such Shares to the Trustee
for cancellation.

          C. Issuances of Shares and Other Securities. After the Effective Date,
             ----------------------------------------
the Trustee or Parent REIT shall not grant, award, or issue any additional
Shares (other than Shares issued pursuant to Section 6.6 hereof, pursuant to a
dividend or distribution (including any share split) of Shares to all of its
shareholders), or in connection with any acquisition permitted by Section 5.5.A
hereof of Qualified Assets, other equity securities of the Trustee, New
Securities or Convertible Funding Debt unless (i) the Trustee shall cause,
pursuant to Section 2.2.A hereof, the Trust to issue to the Trustee Trust
Interests or rights, options, warrants or convertible or exchangeable securities
of the Trust having designations, preferences and other rights, all such that
the economic interests are substantially the same as those of such additional
Shares, other equity securities, New Securities or Convertible Funding Debt, as
the case may be, and (ii) the Trustee transfers to the Trust, as an additional
Capital Contribution, the proceeds from the grant, award, or issuance of such
additional Shares, other equity securities, New Securities or Convertible
Funding Debt, as the case may be, or from the exercise of rights contained in
such additional Shares, other equity securities, New Securities or Convertible
Funding Debt, as the case may be. Without limiting the foregoing, the Parent
REIT is expressly authorized to issue additional Shares, other equity
securities, New Securities or Convertible Funding Debt, as the case may be, for
less than fair market value, and the Trustee is expressly authorized, pursuant
to Section 2.2.A hereof, to cause the Trust to issue to the Trustee
corresponding Trust Interests, as long as (a) the Trustee concludes in good
faith that such issuance is in the interests of the Trustee and the Trust (for
example, and not by way of limitation, the issuance of Shares and corresponding
Units pursuant to a share purchase plan providing for purchases of Shares,
either by employees or shareholders, at a discount from fair market value or
pursuant to employee share options that have an exercise price that is less than
the fair market value of the Shares, either at the time of issuance or at the
time of exercise) and (b) the Trustee transfers all proceeds from any such
issuance or exercise to the Trust as an additional Capital Contribution.

          D. Share Option Plan. If at any time or from time to time, the Trustee
             -----------------
sells Shares pursuant to any Share Option Plan, the Trustee shall transfer the
net proceeds of the sale of such Shares to the Trust as an additional Capital
Contribution in exchange for an amount of additional Units equal to the number
of Shares so sold divided by the Conversion Factor.

          E. Funding Debt. The Trustee or the Parent REIT may incur a Funding
             ------------
Debt, including, without limitation, a Funding Debt that is convertible into
Shares or otherwise constitutes a class of New Securities ("Convertible Funding
Debt"), subject to the condition that the Trustee or the Parent REIT, as the
case may be, lend to the Trust the net proceeds of such Funding Debt; provided
                                                                      --------
that Convertible Funding Debt shall be issued pursuant to Section 5.5.C
----

                                       33

<PAGE>

above; and, provided further that, the Trustee or the Parent REIT shall not be
            -------- -------
obligated to lend the net proceeds of any Funding Debt to the Trust in a manner
that would be inconsistent with the Parent REIT's ability to remain qualified as
a REIT as long as the Parent REIT has determined to continue to qualify as a
REIT. If the Trustee or the Parent REIT enters into any Funding Debt, the loan
to the Trust shall be on comparable terms and conditions, including interest
rate, repayment schedule and costs and expenses, as are applicable with respect
to or incurred in connection with such Funding Debt.

     Section 5.6 Transactions with Affiliates
                 ----------------------------

          A. Transaction with Certain Affiliates. Except as expressly permitted
             -----------------------------------
by this Agreement, the Trust shall not, directly or indirectly, sell, transfer
or convey any property to, or purchase any property from, or borrow funds from,
or lend funds to, any Unitholder (other than the Trustee) or any Affiliate of
the Trust or the Trustee that is not also a Subsidiary of the Trust, except
pursuant to transactions that are determined by the Trustee in good faith, which
determination shall be conclusive, to be on terms that are fair and reasonable
and no less favorable to the Trust than would be obtained from an unaffiliated
third party or that comply with the provisions of Section 2-419 of the Maryland
General Corporation Law.

          B. Conflict Avoidance. The Trustee is expressly authorized to enter
             ------------------
into, in the name and on behalf of the Trust, a noncompetition arrangement,
right of first opportunity arrangement and/or other conflict avoidance
agreements with various Affiliates of the Trust and Trustee on such terms as the
Trustee, in its sole and absolute discretion, believes are advisable.

          C. Benefit Plans. The Trustee in its sole and absolute discretion and
             -------------
without the approval of the other Unitholders, may propose and adopt on behalf
of the Trust employee benefit plans funded by the Trust for the benefit of
employees of the Trustee, the Trust, or Subsidiaries of the Trust.

     Section 5.7 Indemnification
                 ---------------

          A. General. The Trust shall indemnify each Indemnitee to the fullest
             -------
extent provided by the Act from and against any and all losses, claims, damages,
liabilities, joint or several, expenses (including, without limitation,
attorneys fees and other legal fees and expenses), judgments, fines, settlements
and other amounts arising from or in connection with any and all claims,
demands, actions, suits or proceedings, civil, criminal, administrative or
investigative, incurred by the Indemnitee and relating to the Trust or the
Trustee or the operation of, or the ownership of property by, the Trust or the
Trustee as set forth in this Agreement in which any such Indemnitee may be
involved, or is threatened to be involved, as a party or otherwise, unless it is
established by a final determination of a court of competent jurisdiction that:
(i) the act or omission of the Indemnitee was material to the matter giving rise
to the proceeding and either was committed in bad faith or was the result of
active and deliberate dishonesty, (ii) the Indemnitee actually received an
improper personal benefit in money, property or services or (iii) in the case of
any criminal proceeding, the Indemnitee had reasonable cause to believe that the
act or omission was unlawful. The termination of any proceeding by judgment,

                                       34

<PAGE>

order or settlement does not create a presumption that the Indemnitee did not
meet the requisite standard of conduct set forth in this Section 5.7.A. The
termination of any proceeding by conviction or upon a plea of nolo contendere or
its equivalent, or an entry of an order of probation prior to judgment, creates
a rebuttable presumption that the Indemnitee acted in a manner contrary to that
specified in this Section 5.7.A with respect to the subject matter of such
proceeding. Any indemnification pursuant to this Section 5.7 shall be made only
out of the assets of the Trust, and any insurance proceeds from the liability
policy covering the Trustee and any Indemnitee, and neither the Trustee nor any
other Unitholder shall have any obligation to contribute to the capital of the
Trust or otherwise provide funds to enable the Trust to fund its obligations
under this Section 5.7.

          B. Advancement of Expenses. Reasonable expenses expected to be
             -----------------------
incurred by an Indemnitee may be paid or reimbursed by the Trust in advance of
the final disposition of any and all claims, demands, actions, suits or
proceedings, civil, criminal, administrative or investigative made or threatened
against an Indemnitee upon receipt by the Trust of (i) a written affirmation by
the Indemnitee of the Indemnitee's good faith belief that the standard of
conduct necessary for indemnification by the Trust as authorized in Section
5.7.A has been met and (ii) a written undertaking by or on behalf of the
Indemnitee to repay the amount if it shall ultimately be determined that the
standard of conduct has not been met.

          C. No Limitation of Rights. The indemnification provided by this
             -----------------------
Section 5.7 shall be in addition to any other rights to which an Indemnitee or
any other Person may be entitled under any agreement, pursuant to any vote of
the Unitholders, as a matter of law or otherwise, and shall continue as to an
Indemnitee who has ceased to serve in such capacity unless otherwise provided in
a written agreement pursuant to which such Indemnitee is indemnified.

          D. Insurance. The Trust may purchase and maintain insurance on behalf
             ---------
of the Indemnitees and such other Persons as the Trustee shall determine against
any liability that may be asserted against or expenses that may be incurred by
such Person in connection with the Trust's activities, regardless of whether the
Trust would have the power to indemnify such Person against such liability under
the provisions of this Agreement.

          E. Benefit Plan Fiduciary. For purposes of this Section 5.7, (i)
             ----------------------
excise taxes assessed on an Indemnitee, or for which the Indemnitee is otherwise
found liable, with respect to a Plan pursuant to applicable law shall constitute
fines within the meaning of this Section 5.7, and (ii) actions taken or omitted
by the Indemnitee with respect to a Plan in the performance of its duties for a
purpose reasonably believed by it to be in the interest of the participants and
beneficiaries of such Plan shall be deemed to be for a purpose which is not
opposed to the best interests of the Trust.

          F. No Personal Liability for Unitholders. In no event may an
             -------------------------------------
Indemnitee subject any of the Unitholders to personal liability by reason of the
indemnification provisions set forth in this Agreement.

          G. Interested Transactions. An Indemnitee shall not be denied
             -----------------------
indemnification in whole or in part under this Section 5.7 because the
Indemnitee had an interest

                                       35

<PAGE>

in the transaction  with respect to which the  indemnification  applies if
the transaction was otherwise permitted by the terms of this Agreement.

          H. Benefit. The provisions of this Section 5.7 are for the benefit of
             -------
the Indemnitees, their heirs, successors, assigns and administrators and shall
not be deemed to create any rights for the benefit of any other Persons. Any
amendment, modification or repeal of this Section 5.7, or any provision hereof,
shall be prospective only and shall not in any way affect the limitation on the
Trust's liability to any Indemnitee under this Section 5.7 as in effect
immediately prior to such amendment, modification or repeal with respect to
claims arising from or related to matters occurring, in whole or in part, prior
to such amendment, modification or repeal, regardless of when such claims may
arise or be asserted.

          I. Indemnification Payments Not Distribution. If and to the extent any
             -----------------------------------------
payments to the Trustee pursuant to this Section 5.7 constitute gross income to
the Trustee (as opposed to the repayment of advances made on behalf of the
Trust), such amounts shall constitute guaranteed payments within the meaning of
Section 707(c) of the Code, shall be treated consistently therewith by the Trust
and all Unitholders, and shall not be treated as distributions for purposes of
computing the Unitholders' Capital Accounts.

          J. Exception to Indemnification. Notwithstanding anything to the
             ----------------------------
contrary in this Agreement, the Trustee shall not be entitled to indemnification
hereunder for any loss, claim, damage, liability or expense for which the
Trustee is obligated to indemnify the Trust under any other agreement between
the Trustee and the Trust.

     Section 5.8 Liability of the Trustee
                 ------------------------

          A. General. To the maximum extent that Maryland law in effect from
             -------
time to time permits limitation of the liability of trustees of a real estate
investment trust, the Trustee shall not be liable to the Trust or to any
Unitholder for money damages. Neither the amendment nor repeal of this Section
5.8.A, nor the adoption or amendment of any other provision of the Declaration
of Trust inconsistent with this Section 5.8.A, shall apply to or affect in any
respect the applicability of the preceding sentence with respect to any act or
failure to act which occurred prior to such amendment, repeal or adoption. In
the absence of any Maryland statute limiting the liability of trustees of a
Maryland real estate investment trust for money damages in a suit by or on
behalf of the Trust or by any Unitholder, the Trustee shall not be liable to the
Trust or to any Unitholder for money damages except to the extent that (i) the
Trustee actually received an improper benefit or profit in money, property or
services, for the amount of the benefit or profit in money, property or services
actually received; or (ii) a judgment or other final adjudication adverse to the
Trustee is entered in a proceeding based on a finding in the proceeding that the
Trustee's action or failure to act was the result of active and deliberate
dishonesty and was material to the cause of action adjudicated in the
proceeding.

          B. No Obligation to Consider Separate Interests of other Unitholders.
             -----------------------------------------------------------------
The Unitholders (including the Trustee to the extent that its Trust Interest is
not in its capacity as Trustee) expressly acknowledge that the Trustee is acting
on behalf of the Trust and the Trustee's shareholders collectively, that the
Trustee is under no obligation to consider the separate interests

                                       36

<PAGE>

of the other Unitholders (including, without limitation, the tax consequences to
the other Unitholders) in deciding whether to cause the Trust to take (or
decline to take) any actions, and that the Trustee shall not be liable for
monetary damages for losses sustained, liabilities incurred or benefits not
derived by Unitholders in connection with such decisions except as set forth in
Exhibit D, unless the Trustee acted in bad faith and the act or omission was
---------
material to the matter giving rise to the loss, liability or benefit not
derived.

          C. Actions of Agents. Subject to its obligations and duties as Trustee
             -----------------
set forth in Section 5.1.A, the Trustee may exercise any of the powers granted
to it by this Agreement and perform any of the duties imposed upon it hereunder
either directly or by or through its agents. The Trustee shall not be
responsible for any misconduct or negligence on the part of any such agent
appointed by the Trustee in good faith.

          D. Effects of Amendment. Notwithstanding any other provision contained
             --------------------
herein, any amendment, modification or repeal of this Section 5.8 or any
provision hereof shall be prospective only and shall not in any way affect the
limitations on the Trustee's liability to the Trust and the other Unitholders
under this Section 5.8 as in effect immediately prior to such amendment,
modification or repeal with respect to claims arising from or relating to
matters occurring, in whole or in part, prior to such amendment, modification or
repeal, regardless of when such claims may arise or be asserted.

     Section 5.9 Other Matters Concerning the Trustee
                 ------------------------------------

          A. Reliance on Documents. The Trustee may rely and shall be protected
             ---------------------
in acting or refraining from acting upon any resolution, certificate, statement,
instrument, opinion, report, notice, request, consent, order, bond, debenture,
or other paper or document believed by it in good faith to be genuine and to
have been signed or presented by the proper party or parties.

          B. Reliance on Advisors. The Trustee may consult with legal counsel,
             --------------------
accountants, appraisers, management consultants, investment bankers, architects,
engineers, environmental consultants and other consultants and advisers selected
by it, and any act taken or omitted to be taken in reliance upon the opinion of
such Persons as to matters which such Trustee reasonably believes to be within
such Person's professional or expert competence shall be conclusively presumed
to have been done or omitted in good faith and in accordance with such opinion.

          C. Action Through Agents. The Trustee shall have the right, in respect
             ---------------------
of any of its powers or obligations hereunder, to act through any of its duly
authorized officers and a duly appointed attorney or attorneys-in-fact. Each
such attorney shall, to the extent provided by the Trustee in the power of
attorney, have full power and authority to do and perform all and every act and
duty which is permitted or required to be done by the Trustee hereunder.

          D. Actions to Maintain REIT Status or Avoid Taxation of Parent REIT.
             ----------------------------------------------------------------
Notwithstanding any other provisions of this Agreement or the Act, any action of
the Trustee on behalf of the Trust or any decision of the Trustee to refrain
from acting on behalf of the Trust, undertaken in the good faith belief that
such action or omission is necessary or advisable in order

                                       37

<PAGE>

(i) to protect the ability of the Parent REIT to continue to qualify as a REIT
so long as the Parent REIT has determined to continue to qualify as a REIT or
(ii) to allow the Parent REIT to avoid incurring liability for any taxes under
Section 857 or Section 4981 of the Code, is expressly authorized under this
Agreement, and is deemed approved by all of the Unitholders other than the
Trustee.

     Section 5.10 Title to Trust Assets
                  ---------------------

          Title to Trust assets, whether real, personal or mixed and whether
tangible or intangible, shall be deemed to be owned by the Trust as an entity,
and no other Unitholder, individually or collectively, shall have any ownership
interest in such Trust assets or any portion thereof. Title to any or all of the
Trust assets may be held in the name of the Trust, the Trustee or one or more
nominees, as the Trustee may determine, including Affiliates of the Trustee. The
Trustee hereby declares and warrants that any Trust assets for which legal title
is held in the name of the Trustee or any nominee or Affiliate of the Trustee
shall be held by such Person for the use and benefit of the Trust in accordance
with the provisions of this Agreement. All Trust assets shall be recorded as the
property of the Trust in its books and records, irrespective of the name in
which legal title to such Trust assets is held.

     Section 5.11 Reliance by Third Parties
                  -------------------------

          Notwithstanding anything to the contrary in this Agreement, any Person
dealing with the Trust shall be entitled to assume that the Trustee has full
power and authority, without consent or approval of any other Unitholder or
Person, to encumber, sell or otherwise use in any manner any and all assets of
the Trust and to enter into any contracts on behalf of the Trust, and take any
and all actions on behalf of the Trust and such Person shall be entitled to deal
with the Trustee as if the Trustee were the Trust's sole party in interest, both
legally and beneficially. Each Unitholder hereby waives any and all defenses or
other remedies which may be available against such Person to contest, negate or
disaffirm any action of the Trustee in connection with any such dealing. In no
event shall any Person dealing with the Trustee or its representatives be
obligated to ascertain that the terms of this Agreement have been complied with
or to inquire into the necessity or expedience of any act or action of the
Trustee or its representatives. Each and every certificate, document or other
instrument executed on behalf of the Trust by the Trustee or its representatives
shall be conclusive evidence in favor of any and every Person relying thereon or

     Section 6.1 Limitation of Liability
                 -----------------------

          The Unitholders other than the Trustee in its capacity as Trustee
shall have no liability under this Agreement except as expressly provided in
this Agreement, including Section 8.5 and Section 11.3, or under the Act.

     Section 6.2 Management of Business
                 ----------------------

          No Unitholder (other than the Trustee, any of its Affiliates or any

or any of their Affiliates, in their capacity as such) shall take part in the
operation, management or control (within the meaning of the Act) of the Trust's
business, transact any business in the Trust's name or have the power to sign
documents for or otherwise bind the Trust. The transaction of any such business
by the Trustee, any of its Affiliates or any officer, director, employee,
partner, agent or trustee of the Trustee, the Trust or any of their Affiliates,
in their capacity as such, shall not affect, impair or eliminate the limitations
on the liability of the Unitholders (excluding the Trustee) under this
Agreement.

     Section 6.3 Outside Activities of Unitholders
                 ---------------------------------

          Subject to Section 5.5 hereof, and subject to any agreements entered
into pursuant to Section 5.6.B hereof and any other agreements entered into by a
Unitholder other than the Trustee or its Affiliates with the Trust or a
Subsidiary, any Unitholder other than the Trustee and any officer, director,
employee, agent, trustee, Affiliate or shareholder of any Unitholder other than
the Trustee shall be entitled to and may have business interests and engage in
business activities in addition to those relating to the Trust, including
business interests and activities that are in direct competition with the Trust
or that are enhanced by the activities of the Trust. Neither the Trust nor any
Unitholders shall have any rights by virtue of this Agreement in any business
ventures of any other Unitholder. None of the Unitholders (other than the
Trustee) nor any other Person shall have any rights by virtue of this Agreement
or the Trust relationship established hereby in any business ventures of any
other Person (other than the Trustee to the extent expressly provided herein),
and such Person shall have no obligation pursuant to this Agreement to offer any
interest in any such business ventures to the Trust, any Unitholder or any such
other Person, even if such opportunity is of a character which, if presented to
the Trust, any Unitholder or such other Person, could be taken by such Person.

     Section 6.4 Return of Capital
                 -----------------

          Except pursuant to the right of redemption set forth in Section 6.6,
and except in accordance with the terms of any Preferred Units, no Unitholder
shall be entitled to the withdrawal or return of its Capital Contribution,
except to the extent of distributions made

                                       39

<PAGE>

pursuant to this Agreement or upon termination of the Trust as provided herein.
No Unitholder shall have priority over any other Unitholder either as to the
return of Capital Contributions (except as permitted by Article 2 of the
Declaration of Trust) or, as to profits, losses, distributions or credits
(except to the extent provided by Article IV or Exhibit B or as otherwise
                                                ---------
expressly provided in this Agreement).

     Section 6.5 Rights of Unitholders Relating to the Trust
                 -------------------------------------------

          A. General. In addition to other rights provided by this Agreement or
             -------
by the Act, and except as limited by Section 6.5.E, each Unitholder shall have
the right, upon written demand:

          (1)  to obtain a copy of the Trust's federal, state and local income
               tax returns for each fiscal year;

          (2)  to obtain a copy of the Trust's bylaws, minutes of proceedings of
               the holders of the Trust's shares of beneficial interest, an
               annual report of operations prepared in general conformity with
               Section 8-401 of the Act, and any voting trust agreement on file
               at the Trust's principal office; and

          (3)  to obtain a copy of the Declaration of Trust and all amendments
               thereto.

          In addition, any Unitholder that is a holder of 5% or more of the
outstanding Class A-1 Units shall have the right, upon written demand, to obtain
a current list of the name and last known business, residence or mailing address
of each Unitholder and to obtain such financial and other information to which
5% stockholders of a Maryland corporation are entitled under Section 2-513 of
the Maryland General Corporation Law.

          B. Notice of Conversion Factor. The Trust shall notify each
             ---------------------------
Unitholder, upon request, of the then current Conversion Factor and any changes
that have been made thereto.

          C. Notice of Extraordinary Transactions of the Parent REIT. The Parent
             -------------------------------------------------------
REIT shall not make any extraordinary distributions of cash or property to its
shareholders or effect a merger (including, without limitation, a triangular
merger), or other combination with or into another Person, a sale of all or
substantially all of its assets or any other similar extraordinary transaction
without notifying the Unitholders of its intention to make such distribution or
effect such merger, sale or other extraordinary transaction at least twenty (20)
Business Days prior to the record date to determine shareholders eligible to
receive such distribution or to vote upon the approval of such merger, sale or
other extraordinary transaction (or, if no such record date is applicable, at
least twenty (20) business days before consummation of such merger, sale or
other extraordinary transaction); provided, however, that the Trustee, in its
                                  --------  -------
sole discretion, may shorten the required notice period of not less than twenty
(20) business days prior to the record date to determine the shareholders
eligible to vote upon a merger transaction (but not any of the other
transactions covered by this Section 6.5.C.) to a period of not less than ten
(10) Business Days (thereby continuing to afford the holders of Units the
opportunity to redeem Units under Section 6.6 on or prior to the record date for
the shareholder vote on the merger transaction) so

                                       40

<PAGE>

long as (i) the Parent REIT will be the surviving entity in such merger
transaction, (ii) immediately following the merger transaction, Persons who held
voting securities of the Parent REIT immediately prior to such merger
transaction will hold, solely by reason of the ownership of voting securities of
the Parent REIT immediately prior to the merger transaction, voting securities
of the Parent REIT representing not less than fifty one percent (51%) of the
total combined voting power of all outstanding voting securities of the Parent
REIT after such merger, and (iii) in the event that in connection with such
merger transaction the Trust will merge with another entity, the Trust will be
the surviving entity in such merger. This provision for such notice shall not be
deemed (i) to permit any transaction that otherwise is prohibited by this
Agreement or requires the approval by the holders of at least a majority of the
Class A-1 Units or (ii) to require the approval on the part of any one or more
of the Unitholders to a transaction that does not otherwise require such
approval under this Agreement. Parent REIT shall not be required to provide
notice pursuant hereto in advance of public disclosure of the transaction giving
rise to the requirement therefor, but Parent REIT shall not establish a record
date related thereto (or if no record date is applicable, a date for
consummation of such merger, sale or other extraordinary transaction) until at
least twenty (20) Business Days after the date of notice pursuant hereto unless
the proviso in the first sentence is applicable, in which case ten (10) Business
Days shall be substituted therefor. Failure to give or receive such notice or
any defect therein shall not affect the legality or validity of the proceedings
described in this Section 6.5.

          D. Agreement Among Unitholders. The Unitholders agree that the
             ---------------------------
provisions of this Annex A are intended to operate both as provisions of the
Declaration of Trust and in the nature of a shareholders agreement among each of
the Unitholders, and that if one or more provisions is declared not to be an
enforceable provision within a declaration of trust under the Act, the
provisions shall nonetheless be fully binding on all Unitholders pursuant to the
agreement among unitholders.

          E. Confidentiality. Notwithstanding any other provision of this
             ---------------
Section 6.5, the Trustee may keep confidential from the Unitholder, for such
period of time as the Trustee determines in its sole and absolute discretion to
be reasonable, any information that (i) the Trustee reasonably believes to be in
the nature of trade secrets or other information the disclosure of which the
Trustee in good faith believes is not in the best interests of the Trust or
could damage the Trust or its business or (ii) the Trust is required by law or
by agreements with unaffiliated third parties to keep confidential.

     Section 6.6 Redemption Right
                 ----------------

          A. General. (i) Subject to Section 6.6.C, at any time on or after the
             -------
first anniversary date of the issuance of a Common Unit to a Unitholder pursuant
to the Declaration of Trust (which one-year period shall commence upon the
issuance of such Unit regardless of whether such Unit is designated upon
issuance as a Class A-1 Unit or a Class B Unit and shall include the period of
time from the date such Unit is issued to such Unitholder as a Class B Unit
until the date such Unit is converted automatically to a Class A-1 Unit pursuant
to Section 2.2.C hereof), or on or after such date prior to the expiration of
such one-year period as the Trustee, in its sole and absolute discretion,
designates with respect to any or all Class A-1 Units then

                                       41

<PAGE>

outstanding, the holder of a Class A-1 Unit (if other than any Trustee Related
Party) shall have the right (the "Redemption Right") to require the Trust to
                                  ----------------
redeem such Class A Unit, from funds legally available therefor, with such
redemption to occur on the Specified Redemption Date and at a redemption price
equal to and in the form of the Cash Amount to be paid by the Trust (subject to
the Trustee's right to pay such redemption price in Shares pursuant to Section
6.6.B). Any such Redemption Right shall be exercised pursuant to a Notice of
Redemption delivered to the Trust (with a copy to the Trustee) by the Unitholder
who is exercising the Redemption Right (the "Redeeming Unitholder"). A
                                             --------------------
Unitholder other than the Trustee may exercise the Redemption Right from time to
time, without limitation as to frequency, with respect to part or all of the
Class A-1 Units that it owns, as selected by such Unitholder, provided that a
                                                              --------
Unitholder may not exercise the Redemption Right for less than one thousand
(1,000) Class A-1 Units unless such Redeeming Unitholder then holds less than
one thousand (1,000) Class A-1 Units, in which event such Redeeming Unitholder
must exercise the Redemption Right for all of the Class A-1 Units held by such
Redeeming Unitholder, and provided further that, with respect to a Unitholder
                          ----------------
which is an entity, such Unitholder may exercise the Redemption Right for less
than one thousand (1,000) Class A-1 Units without regard to whether or not such
Unitholder is exercising the Redemption Right for all of the Class A-1 Units
held by such Unitholder as long as such Unitholder is exercising the Redemption
Right on behalf of one or more of its equity owners in respect of one hundred
percent (100%) of such equity owners' interests in such Unitholder.
Notwithstanding any limitation in the first sentence hereof, the Redemption
Right with respect to all Class A-1 Units issued in connection with the merger
of Charles E. Smith Residential Realty L.P. into the Trust shall be exercisable
immediately on the issuance of such Class A-1 Units without limitation.

             (ii)  The Redeeming Unitholder shall have no right with respect to
any Class A-1 Units so redeemed to receive any distributions paid after the
Specified Redemption Date with respect to such Class A-1 Units.

             (iii) If the Parent REIT provides notice to the Unitholders
(excluding the Trustee), pursuant to Section 6.5.C hereof, the Redemption Right
shall be exercisable, without regard to whether the Units have been outstanding
for any specified period, during the period commencing on the date on which the
Parent REIT provides such notice and ending on the record date to determine
shareholders eligible to receive such distribution or to vote upon the approval
of such merger, sale or other extraordinary transaction (or, if no such record
date is applicable, at least twenty (20) business days before the consummation
of such merger, sale or other extraordinary transaction). If this subparagraph
(iii) applies, the Specified Redemption Date is the date on which the Trust and
the Trustee receive notice of exercise of the Redemption Right, rather than ten
(10) Business Days after receipt of the notice of redemption.

          B. Trustee Assumption of Right. (i) If a Unitholder other than the
             ---------------------------
Trustee has delivered a Notice of Redemption, the Trustee may, in its sole and
absolute discretion (subject to the limitations on ownership and transfer of
Shares set forth in the Trustee Declaration of Trust), elect to assume directly
and satisfy a Redemption Right by paying to the Redeeming Unitholder either the
Cash Amount or the Shares Amount, as the Trustee determines in its sole and
absolute discretion (provided that payment of the Redemption Amount in the form
                     --------
of Shares shall be in Shares registered for resale under Section 12 of the
Exchange Act and listed

                                       42

<PAGE>

for trading on the exchange or national market on which the Shares are Publicly
Traded and the issuance of Shares upon redemption shall be registered under the
Securities Act or, at the election of the Trustee, resale of the Common Shares
issued upon redemption shall be registered (so long as the Redeeming Unitholder
provides all information required for such registration) and, provided further
                                                              -------- -------
that, if the Shares are not Publicly Traded at the time a Redeeming Unitholder
exercises its Redemption Right, the Redemption Amount shall be paid only in the
form of the Cash Amount unless the Redeeming Unitholder, in its sole and
absolute discretion, consents to payment of the Redemption Amount in the form of
the Shares Amount, on the Specified Redemption Date, whereupon the Trustee shall
acquire the Units offered for redemption by the Redeeming Unitholder and shall
be treated for all purposes of this Agreement as the owner of such Units. Unless
the Trustee, in its sole and absolute discretion, shall exercise its right to
assume directly and satisfy the Redemption Right, the Trustee shall not have any
obligation to the Redeeming Unitholder or to the Trust with respect to the
Redeeming Unitholder's exercise of the Redemption Right. If the Trustee shall
exercise its right to satisfy the Redemption Right in the manner described in
the first sentence of this Section 6.6.B and shall fully perform its obligations
in connection therewith, the Trust shall have no right or obligation to pay any
amount to the Redeeming Unitholder with respect to such Redeeming Unitholder's
exercise of the Redemption Right, and each of the Redeeming Unitholder, the
Trust and the Trustee shall, for federal income tax purposes, treat the
transaction between the Trustee and the Redeeming Unitholder as a sale of the
Redeeming Unitholder's Units to the Trustee. Nothing contained in this Section
6.6.B shall imply any right of the Trustee to require any Unitholder to exercise
the Redemption Right afforded to such Unitholder pursuant to Section 6.6.A.

              (ii)  If the Trustee determines to pay the Redeeming Unitholder
the Redemption Amount in the form of Shares, the total number of Shares to be
paid to the Redeeming Unitholder in exchange for the Redeeming Unitholder's
Class A Units shall be the applicable Shares Amount. If this amount is not a
whole number of Shares, the Redeeming Unitholder shall be paid (i) that number
of Shares which equals the nearest whole number less than such amount plus (ii)
an amount of cash which the Trustee determines, in its reasonable discretion, to
represent the fair value of the remaining fractional Share which would otherwise
be payable to the Redeeming Unitholder.

              (iii) Each Redeeming Unitholder agrees to execute such documents
as the Trustee may reasonably require in connection with the issuance of Shares
upon exercise of the Redemption Right.

              (iv)  Any Shares issued in accordance with this Section 6.6.B will
be duly and validly authorized and will be validly issued, fully paid and
nonassessable and will not be subject to any preemptive rights.

          C.  Exception to Exercise of the Redemption Right. Notwithstanding the
              ---------------------------------------------
provisions of Sections 6.6.A and 6.6.B, a Unitholder shall not be entitled to
exercise the Redemption Right pursuant to Section 6.6.A if (but only as long as)
the delivery of Shares to such Unitholder on the Specified Redemption Date (i)
would be prohibited under those portions of the Trustee Declaration of Trust
relating to restrictions on ownership and transfer of Shares or

                                       43

<PAGE>

(ii) would be prohibited under applicable federal or state securities laws or
regulations (in each case regardless of whether the Trustee would in fact assume
and satisfy the Redemption Right).

          D. No Liens on Units Delivered for Redemption. Each Unitholder
             ------------------------------------------
covenants and agrees with the Trustee that all Class A Units delivered for
redemption shall be delivered to the Trust or the Trustee, as the case may be,
free and clear of all liens, claims and encumbrances; and, notwithstanding
anything contained herein to the contrary, neither the Trustee nor the Trust
shall be under any obligation to acquire Class A Units which are or may be
subject to any liens, claims or encumbrances. Each Unitholder further agrees
that, if any state or local property transfer tax is payable as a result of the
transfer of its Class A Units to the Trust or the Trustee, such Unitholder shall
assume and pay such transfer tax.

          E. Additional Trust Interests; Modification of Holding Period. If the
             ----------------------------------------------------------
Trust issues Trust Interests to any Unitholder pursuant to Article 2, the
Trustee may provide for any restrictions on the exercise of the Redemption Right
with respect to such Trust Interests as it deems appropriate, in its sole and
absolute discretion, provided that no such restrictions shall materially
                     --------
adversely affect the rights of any other Unitholder to exercise its Redemption
Rights without that Unitholder's prior written consent. In addition, the Trustee
may, with respect to any holder or holders of Units, at any time and from time
to time, as it shall determine in its sole discretion, reduce or waive the
length of the period prior to which such holder or holders may not exercise the
Redemption Right.

the Trust those records and documents required to be maintained by the Act and
other books and records deemed by the Trustee to be appropriate with respect to
the Trust's business, including, without limitation, all books and records
necessary to provide to the Unitholders any information, lists and copies of
documents required to be provided pursuant to Section 7.3 hereof. Any records
maintained by or on behalf of the Trust in the regular course of its business
may be kept on, or be in the form of, punch cards, magnetic tape, photographs,
micrographics or any other information storage device, provided that the records
                                                       -------- ----
so maintained are convertible into clearly legible written form within a
reasonable period of time. The books of the Trust shall be maintained, for
financial and tax reporting purposes, on an accrual basis in accordance with
generally accepted accounting principles, or other such basis as the Trustee
determines to be necessary or appropriate.

                   -----------

the date on which the Parent REIT mails its annual report to its shareholders,
the Parent REIT shall cause to be mailed to each Unitholder an annual report, as

solely on a consolidated basis with the Trust, for such Fiscal Year, presented
in accordance with generally accepted accounting principles, such statements to

selected by the Parent REIT.

          B. Quarterly Reports. If and to the extent that the Parent REIT mails
             -----------------
quarterly reports to its shareholders, as soon as practicable, but in no event
later than the date on which such reports are mailed, the Parent REIT shall
cause to be mailed to each Unitholder a report containing unaudited financial
statements, as of the last day of such calendar quarter, of the Trust, or of the
Parent REIT if such statements are prepared solely on a consolidated basis with
the Trust, and such other information as may be required by applicable law or
regulation, or as the Trustee determines to be appropriate.

          C. Parent REIT Communications to Equity Holders. The Trustee shall use
             --------------------------------------------
commercially reasonable efforts to cause to be mailed to each Unitholder a copy
of each written report, proxy statement or other communication sent to holders
of Shares. Such materials will be sent to each Unitholder on the same date on
which they are first sent to holders of Shares.

                   -------------

          Except as otherwise provided herein, the Trustee shall, in its sole
and absolute discretion, determine whether to make any available election
pursuant to the Code; provided, however, that the Trustee shall make the
                      --------  -------
election under Section 754 of the Code in accordance with applicable regulations
thereunder and the Trustee shall have the right to seek to revoke any such
election (including, without limitation, the election under Section 754 of the
Code) upon the Trustee's determination in its sole and absolute discretion that
such revocation is in the best interests of the Unitholders; provided, however,

     Section 8.3   Tax Matters Partner
                   -------------------

          A.   General. The Trustee shall be the "tax matters partner" of the
               -------
Trust for federal income tax purposes. Pursuant to Section 6230(e) of the Code,
upon receipt of notice from the IRS of the beginning of an administrative
proceeding with respect to the Trust, the tax matters partner shall furnish the
IRS with the name, address, taxpayer identification number, and profit interest
of each of the Unitholders; provided, however, that such information is provided
                            --------  -------
to the Trust by the Unitholders.

          B.   Powers. The tax matters partner is authorized, but not required:
               ------

          (1)  to enter into any settlement with the IRS with respect to any
               administrative or judicial proceedings for the adjustment of
               Trust items required to be taken into account by a Unitholder for
               income tax purposes (such administrative proceedings being
               referred to as a "tax audit" and such judicial proceedings being
               referred to as "judicial review"), and in the settlement
               agreement the tax matters partner may expressly state that such
               agreement shall bind all Unitholders, except that such settlement
               agreement shall not bind any Unitholder (i) who (within the time
               prescribed pursuant to the Code and Regulations) files a
               statement with the IRS providing that the tax matters partner
               shall not have the authority to enter into a settlement agreement
               on behalf of such Unitholder or (ii) who is a "notice partner"
               (as defined in Section 6231(a)(8) of the Code) or a member of a
               "notice group" (as defined in Section 6223(b)(2) of the Code);

          (2)  in the event that a notice of a final administrative adjustment
               at the Trust level of any item required to be taken into account
               by a Unitholder for tax purposes (a "final adjustment") is mailed
               to the tax matters partner, to seek judicial review of such final
               adjustment, including the filing of a petition for readjustment
               with the Tax Court or the filing of a complaint for refund with
               the United States Claims Court or the District Court of the
               United States for the district in which the Trust's principal
               place of business is located;

          (3)  to intervene in any action brought by any other Unitholder for
               judicial review of a final adjustment;

          (4)  to file a request for an administrative adjustment with the IRS
               at any time and, if any part of such request is not allowed by
               the IRS, to file an appropriate pleading (petition or complaint)
               for judicial review with respect to such request;

                                       46

<PAGE>

          (5)  to enter into an agreement with the IRS to extend the period for
               assessing any tax which is attributable to any item required to
               be taken into account by a Unitholder for tax purposes, or an
               item affected by such item; and

          (6)  to take any other action on behalf of the Unitholders of the
               Trust in connection with any tax audit or judicial review
               proceeding to the extent permitted by applicable law or
               regulations.

          The taking of any action and the incurring of any expense by the tax
matters partner in connection with any such proceeding, except to the extent
required by law, is a matter in the sole and absolute discretion of the tax
matters partner and the provisions relating to indemnification of the Trustee
set forth in Section 5.7 of this Agreement shall be fully applicable to the tax
matters partner in its capacity as such.

          C. Reimbursement. The tax matters partner shall receive no
             -------------
compensation for its services. All third party costs and expenses incurred by
the tax matters partner in performing its duties as such (including legal and
accounting fees and expenses) shall be borne by the Trust. Nothing herein shall
be construed to restrict the Trust from engaging an accounting firm to assist
the tax matters partner in discharging its duties hereunder, so long as the
compensation paid by the Trust for such services is reasonable.

     Section 8.4   Organizational Expenses
                   -----------------------

          The Trust shall elect to deduct expenses, if any, incurred by it in
organizing the Trust ratably over a sixty (60) month period as provided in
Section 709 of the Code.

     Section 8.5   Withholding
                   -----------

          Each Unitholder hereby authorizes the Trust to withhold from or pay on
behalf of or with respect to such Unitholder any amount of federal, state,
local, or foreign taxes that the Trustee determines that the Trust is required
to withhold or pay with respect to any amount distributable or allocable to such
Unitholder pursuant to this Agreement, including, without limitation, any taxes
required to be withheld or paid by the Trust pursuant to Sections 1441, 1442,
1445, or 1446 of the Code. Any amount paid on behalf of or with respect to a
Unitholder shall constitute a loan by the Trust to such Unitholder, which loan
shall be repaid by such Unitholder within fifteen (15) days after notice from
the Trustee that such payment must be made unless (i) the Trust withholds such
payment from a distribution which would otherwise be made to the Unitholder or
(ii) the Trustee determines, in its sole and absolute discretion, that such
payment may be satisfied out of the available funds of the Trust which would,
but for such payment, be distributed to the Unitholder. Any amounts withheld
pursuant to the foregoing clause (i) or (ii) shall be treated as having been
distributed to such Unitholder. Each Unitholder hereby unconditionally and
irrevocably grants to the Trust a security interest in such Unitholder's Trust
Interest to secure such Unitholder's obligation to pay to the Trust any amounts
required to be paid pursuant to this Section 8.5. In the event that a Unitholder
fails to pay any amounts owed to the Trust pursuant to this Section 8.5 when
due, the Trustee may, in its sole and absolute

                                       47

<PAGE>

discretion, elect to make the payment to the Trust on behalf of such defaulting
Unitholder, and in such event shall be deemed to have loaned such amount to such
defaulting Unitholder and shall succeed to all rights and remedies of the Trust
as against such defaulting Unitholder. Without limitation, in such event the
Trustee shall have the right to receive distributions that would otherwise be
distributable to such defaulting Unitholder until such time as such loan,
together with all interest thereon, has been paid in full, and any such
distributions so received by the Trustee shall be treated as having been
distributed to the defaulting Unitholder and immediately paid by the defaulting
Unitholder to the Trustee in repayment of such loan. Any amounts payable by a
Unitholder hereunder shall bear interest at the lesser of (A) the base rate on
corporate loans at large United States money center commercial banks, as
published from time to time in the Wall Street Journal, plus four (4) percentage
                                   -------------------
points, or (B) the maximum lawful rate of interest on such obligation, such
interest to accrue from the date such amount is due (i.e., fifteen (15) days
after demand) until such amount is paid in full. Each Unitholder shall take such
actions as the Trust or the Trustee shall request in order to perfect or enforce
the security interest created hereunder.

                            TRANSFERS AND WITHDRAWALS

     Section 9.1   Transfer
                   --------

          A. Definition. The term "transfer," when used in this Article 9 with
             ----------
respect to a Trust Interest or Unit, shall be deemed to refer to a transaction
by which the Trustee purports to assign all or any part of its Trust Interest to
another Person or by which a Unitholder purports to assign all or any part of
its Trust Interest to another Person, and includes a sale, assignment, gift,
pledge, encumbrance, hypothecation, mortgage, exchange or any other disposition
by law or otherwise. The term "transfer" when used in this Article 9 does not
include any redemption of Units by a Unitholder or acquisition of Units from a
Unitholder by the Trustee pursuant to Section 6.6 or otherwise. No part of the
interest of a Unitholder shall be subject to the claims of any creditor, any
spouse for alimony or support, or to legal process, and may not be voluntarily
or involuntarily alienated or encumbered except as may be specifically provided
for in this Agreement or as required by law.

          B. General. No Trust Interest shall be transferred, in whole or in
             -------
part, except in accordance with the terms and conditions set forth in this
Article 9. Any transfer or purported transfer of a Trust Interest not made in
accordance with this Article 9 shall be null and void.

     Section 9.2   Transfer of Trustee's Trust Interest
                   ------------------------------------

          A. General. Except for transfers of Units to the Trust as provided in
             -------
Section 5.5 or Section 6.6, the Trustee may not transfer any of its Trust
Interest except in connection with a transaction described in Section 9.2.B or
as otherwise expressly permitted under this

                                       48

<PAGE>

Agreement, nor shall the Trustee withdraw as the Trustee except in connection
with a transaction described in Section 9.2.B.

          B. Specific Transaction Prohibited. The Parent REIT shall not engage
             -------------------------------
in any merger (including a triangular merger), consolidation or other
combination with or into another person, sale of all or substantially all of its
assets or any reclassification, recapitalization or change of outstanding Shares
(other than a change in par value, or from par value to no par value, or as a
result of a subdivision or combination as described in the definition of
"Conversion Factor") ("Termination Transaction"), unless (i) the Termination
                       -----------------------
Transaction has been approved by the Unitholders holding at least a majority of
the then outstanding Units (including any Units held by the Trustee), (ii)
following such merger or other consolidation, substantially all of the assets of
the surviving entity consist of Units, and (iii) in connection with such
termination transaction all Unitholders either will receive, or will have the
right to elect to receive, for each Unit an amount of cash, securities, or other
property equal to the product of the Conversion Factor multiplied by the
greatest amount of cash, securities or other property paid to a holder of Shares
corresponding to such Unit in consideration of one such Share at any time during
the period from and after the date on which the Termination Transaction is
consummated; provided that if, in connection with the Termination Transaction, a
             -------- ----
purchase, tender or exchange offer shall have been made to and accepted by the
holders of more than fifty percent (50%) of the outstanding common shares of
beneficial interest (or other comparable equity interest) of the Parent REIT,
each holder of Units shall receive, or shall have the right to elect to receive
without any right of approval set forth above in this subsection B, the greatest
amount of cash, securities, or other property which such holder would have
received had it exercised the Redemption Right and received Shares in exchange
for its Units immediately prior to the expiration of such purchase, tender or
exchange offer and had thereupon accepted such purchase, tender or exchange
offer. The Trustee shall not enter into an agreement or other arrangement
providing for or facilitating the creation of a Parent REIT other than the
Trustee, unless the successor Parent REIT executes and delivers a counterpart to
this Agreement in which such Parent REIT successor agrees to be fully bound by
all of the terms and conditions contained herein that are applicable to a Parent
REIT.

     Section 9.3   Unitholders' Rights to Transfer
                   -------------------------------

          A. General. Except to the extent expressly permitted in Sections 9.3.B
             -------
and 9.3.C or in connection with the exercise of a Redemption Right pursuant to
Section 6.6, a Unitholder may not transfer all or any portion of its Trust
Interest, or any of such Unitholder's rights as a Unitholder, without the prior
written consent of the Trustee, which consent may be withheld in the Trustee's
sole and absolute discretion. Any transfer otherwise permitted under Sections
9.3.B and 9.3.C shall be subject to the conditions set forth in Section 9.3.D,
9.3.E and 9.3.F, and all permitted transfers shall be subject to Section 9.4.

          B. Incapacitated Unitholders. If a Unitholder is subject to
             -------------------------
Incapacity, the executor, administrator, trustee, committee, guardian,
conservator or receiver of such Unitholder's estate shall have all the rights of
a Unitholder, but not more rights than those enjoyed by other Unitholders, for
the purpose of settling or managing the estate and such power

                                       49

<PAGE>

as the Incapacitated Unitholder possessed to transfer all or any part of its
interest in the Trust. The Incapacity of a Unitholder, in and of itself, shall
not dissolve or terminate the Trust.

          C.   Permitted Transfers. A Unitholder may transfer, with or without
               -------------------
the consent of the Trustee, all or a portion of its Trust Interest (i) in the
case of a Unitholder who is an individual, to a member of his Immediate Family,
any trust formed for the benefit of himself and/or members of his Immediate
Family, or any partnership, limited liability company, joint venture,
corporation or other business entity comprised only of himself and/or members of
his Immediate Family and entities the ownership interests in which are owned by
or for the benefit of himself and/or members of his Immediate Family, (ii) in
the case of a Unitholder which is a trust, to the beneficiaries of such trust,
(iii) in the case of a Unitholder which is a partnership, limited liability
company, joint venture, corporation or other business entity to which Units were
transferred pursuant to clause (i) above, to its partners, owners or
stockholders, as the case may be, who are members of the Immediate Family of or
are actually the Person(s) who transferred Units to it pursuant to clause (i)
above, (iv) in the case of a Unitholder which acquired Units as of the date
hereof and which is a partnership, limited liability company, joint venture,
corporation or other business entity, to its partners, owners, stockholders or
Affiliates thereof, as the case may be, or the Persons owning the beneficial
interests in any of its partners, owners or stockholders or Affiliates thereof
(it being understood that this clause (iv) will apply to all of each Person's
Trust Interests whether the Units relating thereto were acquired on the date
hereof or hereafter), (v) in the case of a Unitholder which is a partnership,
limited liability company, joint venture, corporation or other business entity
other than any of the foregoing described in clause (iii) or (iv), in accordance
with the terms of any agreement between such Unitholder and the Trust pursuant
to which such Trust Interest was issued, (vi) pursuant to a gift or other
transfer without consideration, (vii) pursuant to applicable laws of descent or
distribution, (viii) to another Unitholder and (ix) pursuant to a grant of
security interest or other encumbrance effectuated in a bona fide transaction or
                                                        ---- ----
as a result of the exercise of remedies related thereto, subject to the
provisions of Section 9.3.F hereof. A trust or other entity will be considered
formed "for the benefit" of a Unitholder's Immediate Family even though some
other Person has a remainder interest under or with respect to such trust or
other entity.

          D.   No Transfers Violating Securities Laws. The Trustee may prohibit
               --------------------------------------
any transfer of Units by a Unitholder unless it receives a written opinion of
legal counsel (which opinion and counsel shall be reasonably satisfactory to the
Trust) to such Unitholder to the effect that such transfer would not require
filing of a registration statement under the Securities Act or would not
otherwise violate any federal or state securities laws or regulations applicable
to the Trust or the transfer of such Units or, at the option of the Trust, an
opinion of legal counsel to the Trust to the same effect.

          E.   No Transfers Affecting Tax Status of Trust. No transfer of Units
               ------------------------------------------
by a Unitholder (including a redemption or exchange pursuant to Section 6.6) may
be made to any Person if (i) in the opinion of legal counsel for the Trust, it
would result in the Trust being treated as an association taxable as a
corporation for federal income tax purposes (except as a result of the
redemption or exchange for Shares of all Units held by all Unitholders other
than the Trustee or the Parent REIT or any Subsidiary of either the Trustee or
the Parent REIT or pursuant to a transaction expressly permitted under Section
5.3.B or Section 9.2), (ii) in the opinion of legal

                                       50

<PAGE>

counsel for the Trust, it could reasonably be expected to cause the Parent REIT
to no longer qualify as a REIT or would subject the Parent REIT to any
additional taxes under Section 857 or Section 4981 of the Code or (iii) such
transfer is effectuated through an "established securities market" or a
"secondary market (or the substantial equivalent thereof)" within the meaning of
Section 7704 of the Code.

          F.   No Transfers to Holders of Nonrecourse Liabilities. No Pledge or
               --------------------------------------------------
transfer of any Units may be made to a lender to the Trust or any Person who is
related (within the meaning of Section 1.752-4(b) of the Regulations) to any
lender to the Trust whose loan constitutes a Nonrecourse Liability unless (i)
the Trustee is provided notice thereof, and (ii) the lender enters into an
arrangement with the Trust and the Trustee to exchange or redeem for the
Redemption Amount any Units in which a security interest is held simultaneously
with the time at which such lender would be deemed to be a Unitholder in the
Trust for purposes of allocating liabilities to such lender under Section 752 of
the Code.

     Section 9.4 General Provisions
                 ------------------

          A.   Timing of Transfers. Transfers pursuant to this Article 9 may
               -------------------
only be made on the first day of a fiscal quarter of the Trust, unless the
Trustee otherwise agrees.

          B.   Allocations. If any Trust Interest is transferred or assigned in
               -----------
compliance with the provisions of this Article 9 or redeemed or transferred
pursuant to Section 6.6, on any day other than the first day of a Fiscal Year,
then Net Income, Net Losses, each item thereof and all other items attributable
to such interest for such Fiscal Year shall be divided and allocated between the
transferor Unitholder and the transferee Unitholder by taking into account their
varying interests during the Fiscal Year in accordance with Section 706(d) of
the Code, using the interim closing of the books method (unless the Trustee, in
its sole and absolute discretion, elects to adopt a daily, weekly or monthly
proration method, in which event Net Income, Net Losses and each item thereof
for such Fiscal Year shall be prorated based upon the applicable period selected
by the Trustee). Solely for purposes of making such allocations, each of such
items for the calendar month in which the transfer or assignment occurs shall be
allocated to the transferee Unitholder, and none of such items for the calendar
month in which a redemption occurs shall be allocated to the Redeeming
Unitholder. All distributions of Available Cash attributable to such Unit with
respect to which the Trust Record Date is before the date of such transfer,
assignment or redemption shall be made to the transferor Unitholder or the
Redeeming Unitholder, as the case may be, and, in the case of a transfer or
assignment other than a redemption, all distributions of Available Cash
thereafter attributable to such Unit shall be made to the transferee Unitholder.

          C.   Additional Restrictions. In addition to any other restrictions on
               -----------------------
transfer herein contained, including without limitation the provisions of this
Article 9 and Article 5, in no event may any transfer or assignment of a Trust
Interest by any Unitholder (including pursuant to Section 6.6) be made without
the express consent of the Trustee, in its sole and absolute discretion, (i) to
any person or entity who lacks the legal right, power or capacity to own a Trust
Interest; (ii) in violation of applicable law; (iii) of any component portion of
a Trust Interest, such as the Capital Account, or rights to distributions,
separate and apart from all other components of a Trust Interest; (iv) if in the
opinion of legal counsel to the Trust such transfer would cause a

                                       51

<PAGE>

termination of the Trust for federal or state income tax purposes (except as a
result of the redemption or exchange for Shares of all Units held by all
Unitholders other than the Trustee, the Parent REIT, or any Subsidiary of
either, or pursuant to a transaction expressly permitted under Section 5.3.B or
Section 9.2); (v) if such transfer would, in the opinion of counsel to the
Trust, cause any portion of the assets of the Trust to constitute assets of any
ERISA Plan Investor pursuant to 29 C.F.R. (S) 2510.3-101, or any successor
regulation thereto; (vi) if such transfer subjects the Trust or the activities
of the Trust to regulation under the Investment Company Act of 1940, the
Investment Advisors Act of 1940 or ERISA, each as amended; or (vii) if such
transfer could reasonably be expected to cause the Parent REIT to fail to remain
qualified as a REIT so long as Parent REIT has determined to continue to qualify
as a REIT.

          D.   Avoidance of "Publicly Traded Partnership" Status. The Trustee
               -------------------------------------------------
shall monitor the transfers of interests in the Trust to determine (i) if such
interests are being traded on an "established securities market" or a "secondary
market (or the substantial equivalent thereof)" within the meaning of Section
7704 of the Code and (ii) whether additional transfers of interests would result
in the Trust being unable to qualify for at least one of the "safe harbors" set
forth in Regulations Section 1.7704-1 (or such other guidance subsequently
published by the IRS setting forth safe harbors under which interests will not
be treated as "readily tradable on a secondary market (or the substantial
equivalent thereof)" within the meaning of Section 7704 of the Code) (the "Safe
                                                                           ----
Harbors"). The Trustee shall take all steps reasonably necessary or appropriate
-------
to prevent any trading of interests or any recognition by the Trust of transfers
made on such markets and, except as otherwise provided herein, to insure that at
least one of the Safe Harbors is met; provided, however, that the foregoing
shall not authorize the Trustee to limit or restrict in any manner the right of
any Unitholder to exercise the Redemption Right in accordance with the terms of
Section 6.6 unless, and only to the extent that, outside tax counsel provides to
the Trustee an opinion to the effect that, in the absence of such limitation or
restriction, there is a significant risk that the Trust will be treated as a
"publicly traded partnership" and, by reason thereof, will be taxable as a
corporation.

                             ADDITIONAL UNITHOLDERS

     Section 10.1  Additional Unitholders
                   ----------------------

          A.   General. A Person who makes a Capital Contribution to the Trust
               -------
in accordance with this Agreement or who exercises an option to receive Units
shall become a Unitholder only with the consent of the Trustee and only upon
furnishing to the Trustee (i) evidence of acceptance in form satisfactory to the
Trustee of all of the terms and conditions of this Agreement, and (ii) such
other documents or instruments as may be required in the discretion of the
Trustee for such Person to become a Unitholder. Any such Person shall become a
Unitholder effective on the date upon which the name of such Person is recorded
on the books and records of the Trust, following the consent of the Trustee.

                                       52

<PAGE>

          B.   Allocations to Additional Unitholders. If any Person becomes a
               -------------------------------------
Unitholder on any day other than the first day of a Fiscal Year, then Net
Income, Net Losses, each item thereof and all other items allocable among
Unitholders for such Fiscal Year shall be allocated among such Unitholder and
all other Unitholders by taking into account their varying interests during the
Fiscal Year in accordance with Section 706(d) of the Code, using the interim
closing of the books method (unless the Trustee, in its sole and absolute
discretion, elects to adopt a daily, weekly or monthly proration method, in
which event Net Income, Net Losses, and each item thereof would be prorated
based upon the applicable period selected by the Trustee). Solely for purposes
of making such allocations, each of such items for the calendar month in which a
Person becomes a Unitholder shall be allocated among all the Unitholders,
including such new Unitholder. All distributions of Available Cash with respect
to which the Trust Record Date is before the date of such admission shall be
made solely to Unitholders other than the new Unitholder, and all distributions
of Available Cash thereafter shall be made to all the Unitholders, including
such new Unitholder.

     Section 11.1 Dissolution
                  -----------

          The Trust shall dissolve, and its affairs shall be wound up, upon the
first to occur of any of the following ("Liquidating Events"):

and who received, with respect to such Smith Units, one or more Class A Units
upon the merger of Charles E. Smith Residential Realty L.P. into the Trust on

               (ii)  from and after January 1, 2014 through December 31, 2043,
an election to dissolve the Trust upon the approval of the Trustee and the

shall continue solely for the purposes of winding up its affairs in an orderly
manner, liquidating its assets, and satisfying the claims of its creditors and
Unitholders. No Unitholder shall take any action that is inconsistent with, or
not necessary to or appropriate for, the winding up of the Trust's business and
affairs. The Trustee (or, if there is no remaining Trustee, any Person elected
by a majority in interest of the Unitholders (the "Liquidator")) shall be
                                                   ----------
responsible for overseeing the winding up and dissolution of the Trust and shall
take full account of the Trust's liabilities and property and the Trust property
shall be liquidated as promptly as is consistent with obtaining the fair value
thereof, and the proceeds therefrom (which may, to the extent determined by the
Trustee, include equity or other securities of the Trustee or any other entity)
shall be applied and distributed in the following order:

          (1) First, to the payment and discharge of all of the Trust's debts
              and liabilities to creditors other than the Unitholders;

          (2) Second, to the payment and discharge of all of the Trust's debts
              and liabilities to the Trustee;

          (3) Third, to the payment and discharge of all of the Trust's debts
              and liabilities to the Unitholders;

          (4) Fourth, to the holders of Trust Interests that are entitled to any
              preference in distribution upon liquidation in accordance with the
              rights of any such class or series of Trust Interests, including
              without limitation, Series A Preferred Units, Series B Junior
              Participating Preferred Units, Series C Preferred Units, Series D
              Preferred Units, Series E Preferred Units, Series F Preferred
              Units, Series G Preferred Units, Series H Preferred Units, Series
              I Preferred Units, Series J Preferred Units, Series K Preferred
              Units and Series L Preferred Units (and, within each such class or
              series, to each holder thereof pro rata based on the proportion of
              the total number of outstanding units of such class or series
              represented by such holder's units of such series or class); and

          (5) The balance, if any, to the Unitholders in accordance with their
              Capital Accounts, after giving effect to all contributions,
              distributions, and allocations for all periods.

          The Trustee shall not receive any additional compensation for any
services performed pursuant to this Article 11.

          B.   Deferred Liquidation. Notwithstanding the provisions of Section
               --------------------
11.2.A which require liquidation of the assets of the Trust, but subject to the
order of priorities set forth therein, if prior to or upon dissolution of the
Trust the Liquidator determines that an immediate sale of part or all of the
Trust's assets would be impractical or would cause undue loss to the
Unitholders, the Liquidator may, in its sole and absolute discretion, defer for
a reasonable time the liquidation of any assets except those necessary to
satisfy liabilities of the Trust (including to those Unitholders as creditors)
or distribute to the Unitholders, in lieu of cash, as tenants in common and in
accordance with the provisions of Section 11.2.A, undivided interests in such
Trust assets as the Liquidator deems not suitable for liquidation. Any such
distributions in kind shall be made only if, in the good faith judgment of the
Liquidator, such distributions in kind are in the best interest of the
Unitholders, and shall be subject to such conditions relating to the disposition
and management of such properties as the Liquidator deems reasonable and
equitable and to any agreements governing the operation of such properties at
such time. The Liquidator shall determine the fair market value of any property
distributed in kind using such reasonable method of valuation as it may adopt.

                    Restoration of eficit Capital Accounts
                    --------------------------------------

          A.   Timing of Distributions. If the Trust is "liquidated" within the
               -----------------------
meaning of Regulations Section 1.704-1(b)(2)(ii)(g), distributions shall be made
under this Article 11 to the Trustee and Unitholders who have positive Capital
Accounts in compliance with Regulations Section 1.704-1(b)(2)(ii)(b)(2). In the
discretion of the Trustee, a pro rata portion of the distributions that would
otherwise be made to the Trustee and Unitholders pursuant to this Article 11 may
be: (A) distributed to a trust established for the benefit of the Trustee and
Unitholders for the purposes of liquidating Trust assets, collecting amounts
owed to the Trust and paying any contingent or unforeseen liabilities or
obligations of the Trust or of the Trustee arising out of or in connection with
the Trust (in which case the assets of any such trust shall be distributed to
the Trustee and Unitholders from time to time, in the reasonable discretion of
the Trustee, in the same proportions as the amount distributed to such trust by
the Trust would otherwise have been distributed to the Trustee and Unitholders
pursuant to this Agreement); or (B) withheld to provide a reasonable reserve for
Trust liabilities (contingent or otherwise) and to reflect the unrealized
portion of any installment obligations owed to the Trust; provided that such
                                                          --------
withheld amounts shall be distributed to the Trustee and Unitholders as soon as
practicable.

          B.   Restoration of Deficit Capital Accounts Upon Liquidation of the
               ---------------------------------------------------------------
Trust. If any Unitholder has a deficit balance in its Capital Account (after
giving effect to all contributions, distributions and allocations for all
taxable years, including the year during which such liquidation occurs), such
Unitholder shall have no obligation to make any contribution to the capital of
the Trust with respect to such deficit, and such deficit shall not be considered
a debt owed to the Trust or to any other Person for any purpose whatsoever,
except as otherwise set forth in this Section 11.3.B, or as otherwise expressly
agreed in writing by the affected

                                       55

<PAGE>

Unitholder and the Trust after the date hereof. Notwithstanding the foregoing,
(i) if the Trustee has a deficit balance in its Capital Account (after giving
effect to all contributions, distributions, and allocations for all Fiscal Years
or portions thereof, including the year during which such liquidation occurs),
the Trustee shall contribute to the capital of the Trust the amount necessary to
restore such deficit balance to zero in compliance with Regulations Section
1.704-1(b)(2)(ii)(b)(3); (ii) if a Protected Unitholder has a deficit balance in
its Capital Account (after giving effect to all contributions, distributions,
and allocations for all Fiscal Years or portions thereof, including the year
during which such liquidation occurs), such Protected Unitholder shall be
obligated to make a contribution to the Trust with respect to any such deficit
balance in such Protected Unitholder's Capital Account upon a liquidation of the
Trust in an amount equal to the lesser of such deficit balance or such Protected
Unitholder's Protected Amount; and (iii) the first sentence of this Section
11.3.B shall not apply with respect to any other Unitholder to the extent, but
only to such extent, that such Unitholder previously has agreed in writing, with
the consent of the Trustee, to undertake an express obligation to restore all or
any portion of a deficit that may exist in its Capital Account upon a
liquidation of the Trust. No Unitholder shall have any right to become a
Protected Unitholder, to increase its Protected Amount, or otherwise agree to
restore any portion of any deficit that may exist in its Capital Account,
without the express written consent of the Trustee, in its sole and absolute
discretion, except as provided for in Exhibit D. Any contribution required of a
                                      ---------
Unitholder under this Section 11.3.B. shall be made on or before the later of
(i) the end of the Fiscal Year in which the interest is liquidated or (ii) the
ninetieth (90/th/) day following the date of such liquidation. The proceeds of
any contribution to the Trust made by a Protected Unitholder with respect to a
deficit in such Protected Unitholder's Capital Account balance shall be treated
as a Capital Contribution by such Protected Unitholder and the proceeds thereof
shall be treated as assets of the Trust to be applied as set forth in Section
11.2.A.

          C.   Restoration of Deficit Capital Accounts Upon a Liquidation of a
               ---------------------------------------------------------------
Unitholder's Interest by Transfer. If a Protected Unitholder's interest in the
---------------------------------
Trust is "liquidated" within the meaning of Regulations Section

1.704-1(b)(2)(ii)(g) (other than in connection with a liquidation of the Trust)
which term shall include a redemption by the Trust of such Protected
Unitholder's interest upon exercise of the Redemption Right, and such Protected
Unitholder is designated on Exhibit C as a Part II Protected Unitholder, such
                            ---------
Protected Unitholder shall be required to contribute cash to the Trust equal to
the lesser of (i) the amount required to increase its Capital Account balance as
of such date to zero, or (ii) such Protected Unitholder's Protected Amount. For
this purpose, (i) the Protected Unitholder's deficit Capital Account balance
shall be determined by taking into account all contributions, distributions, and
allocations for the portion of the Fiscal Year ending on the date of the
liquidation or redemption, and (ii) solely for purposes of determining such
Protected Unitholder's Capital Account balance, the Trustee shall redetermine
the Carrying Value of the Trust's assets on such date based upon the principles
set forth in Sections 1.D.(3) and (4) of Exhibit A hereto, and shall take into
                                         ---------
account the Protected Unitholder's allocable share of any Unrealized Gain or
Unrealized Loss resulting from such redetermination in determining the balance
of its Capital Account. The amount of any payment required hereunder shall be
due and payable within the time period specified in the second to last sentence
of Section 11.3.B.

          D.   Effect of the Death of a Protected Unitholder. After the death of
               ---------------------------------------------
a Protected Unitholder who is an individual, the executor of the estate of such
Protected Unitholder may elect to reduce (or eliminate) the Protected Amount of
such Protected Unitholder. Such elections may be made by such executor by
delivering to the Trustee within two hundred and seventy (270) days of the death
of such Unitholder, a written notice setting forth the maximum deficit balance
in its Capital Account that such executor agrees to restore under this Section
11.3, if any. If such executor does not make a timely election pursuant to this
Section 11.3 (whether or not the balance in the applicable Capital Account is
negative at such time), then the Protected Unitholder's estate (and the
beneficiaries thereof who receive distributions of Trust Interests therefrom)
shall be deemed a Protected Unitholder with a Protected Amount in the same
amount as the deceased Protected Unitholder. Any Protected Unitholder which is a
partnership may likewise elect, after the date of its partner's death to reduce
(or eliminate) its Protected Amount by delivering a similar notice to the
Trustee within the time period specified above, and in the absence of any such
notice the Protected Amount of such Protected Unitholder shall not be reduced to
reflect the death of any of its partners.

     Section 11.4 Rights of Unitholders
                  ---------------------

          Except as otherwise provided in this Agreement, each Unitholder shall
look solely to the assets of the Trust for the return of its Capital
Contributions and shall have no right or power to demand or receive property
other than cash from the Trust. Except as otherwise expressly provided in this
Agreement, no Unitholder shall have priority over any other Unitholder as to the
return of its Capital Contributions, distributions, or allocations.

     Section 11.5 Notice of Dissolution
                  ---------------------

          If a Liquidating Event occurs or an event occurs that would, but for
provisions of an election or objection by one or more Unitholders pursuant to
Section 11.1, result in a dissolution of the Trust, the Trustee shall, within
thirty (30) days thereafter, provide written notice thereof to each of the
Unitholders.

     Section 11.6 Reasonable Time for Winding-Up
                  ------------------------------

          A reasonable time shall be allowed for the orderly winding-up of the
business and affairs of the Trust and the liquidation of its assets pursuant to
Section 11.2 hereof, in order to minimize any losses otherwise attendant upon
such winding-up, and the provisions of this Agreement shall remain in effect
among the Unitholders during the period of liquidation.

     Section 11.7 Waiver of Partition
                  -------------------

          Each Unitholder hereby waives any right to partition of the Trust
property.

     Section 11.8  Liability of the Liquidator
                   ---------------------------

          The Liquidator shall be indemnified and held harmless by the Trust in
the same manner and to the same degree as an Indemnitee may be indemnified
pursuant to Section 5.7.

               Agreement that will not be inconsistent with law or with the

     -----------------------------------

     A.  The Trust shall maintain for each Unitholder a separate Capital Account

Capital Account shall be increased by (i) the amount of all Capital
Contributions and any other deemed contributions made by such Unitholder to the
Trust pursuant to this Agreement and (ii) all items of Trust income and gain
(including income and gain exempt from tax) computed in accordance with Section

     B.  For purposes of computing the amount of any item of income, gain,
deduction or loss to be reflected in the Unitholders' Capital Accounts, unless
otherwise specified in this Agreement, the determination, recognition and
classification of any such item shall be the same as its determination,

               gain, loss and deduction shall be made without regard to any
               election under Section 754 of the Code which may be made by the
               Trust, provided that the amounts of any adjustments to the
               adjusted bases of the assets of the Trust made pursuant to
               Section 734 of the Code as a result of the distribution of
               property by the Trust to a Unitholder (to the extent that such
               adjustments have not previously been reflected in the
               Unitholders' Capital Accounts) shall be reflected in the Capital
               Accounts of the Unitholders in the manner and subject to the
               limitations prescribed in Regulations Section
               1.704-1(b)(2)(iv)(m)(4).

         (2)   The computation of all items of income, gain, and deduction shall
               be made without regard to the fact that items described in
               Sections 705(a)(1)(B) or 705(a)(2)(B) of the Code are not
               includable in gross income or are neither currently deductible
               nor capitalized for federal income tax purposes.

         (3)   Any income, gain or loss attributable to the taxable disposition
               of any Trust property shall be determined as if the adjusted
               basis of such property as of such date of disposition were equal
               in amount to the Trust's Carrying Value with respect to such
               property as of such date.

                                        1

          (4)  In lieu of the depreciation, amortization, and other cost
               recovery deductions taken into account in computing such taxable
               income or loss, there shall be taken into account Depreciation
               for such fiscal year.

          (5)  In the event the Carrying Value of any Trust Asset is adjusted
               pursuant to Section 1.D hereof, the amount of any such adjustment
               shall be taken into account as gain or loss from the disposition
               of such asset.

          (6)  Any items specially allocated under Section 2 of Exhibit B to the
                                                                ---------
               Agreement hereof shall not be taken into account.

     C.   A transferee of a Unit shall succeed to a pro rata portion of the
Capital Account of the transferor.

     D.   (1)  Consistent with the provisions of Regulations Section 1.704-1(b)
               (2)(iv)(f), and as provided in Section 1.D (2), the Carrying
               Values of all Trust assets shall be adjusted upward or downward
               to reflect any Unrealized Gain or Unrealized Loss attributable to
               such Trust property, as of the times of the adjustments provided
               in Section 1.D (2) hereof, as if such Unrealized Gain or
               Unrealized Loss had been recognized on an actual sale of each
               such property and allocated pursuant to Section 4.1 of the
               Agreement.

          (2)  Such adjustments shall be made as of the following times: (a)
               immediately prior to the acquisition of an additional interest in
               the Trust by any new or existing Unitholder in exchange for more
               than a de minimis Capital Contribution; (b) immediately prior to
               the distribution by the Trust to a Unitholder of more than a de
               minimis amount of property as consideration for an interest in
               the Trust; and (c) immediately prior to the liquidation of the
               Trust within the meaning of Regulations Section
               1.704-1(b)(2)(ii)(g), provided however that adjustments pursuant
                                     -------- -------
               to clauses (a) and (b) above shall be made only if the Trustee
               determines that such adjustments are necessary or appropriate to
               reflect the relative economic interests of the Unitholders of the
               Trust.

          (3)  In accordance with Regulations Section 1.704-1(b)(2)(iv)(e), the
               Carrying Value of Trust assets distributed in kind shall be
               adjusted upward or downward to reflect any Unrealized Gain or
               Unrealized Loss attributable to such Trust property, as of the
               time any such asset is distributed.

          (4)  In determining Unrealized Gain or Unrealized Loss for purposes of
               this Exhibit A, the aggregate cash amount and fair market value
                    ----------
               of all Trust assets (including cash or cash equivalents) shall be
               determined by the Trustee using such reasonable method of
               valuation as it may adopt, or in the case of a liquidating
               distribution pursuant to Article 11 of the Agreement, shall be
               determined and allocated by the Liquidator using such reasonable
               methods of valuation as it may adopt. The Trustee, or the

                                        2

<PAGE>

               Liquidator, as the case may be, shall allocate such aggregate
               fair market value among the assets of the Trust (in such manner
               as it determines in its sole and absolute discretion to arrive at
               a fair market value for individual properties).

     E.   The provisions of the Agreement (including this Exhibit A and the
                                                          ---------
other Exhibits to the Agreement) relating to the maintenance of Capital Accounts
are intended to comply with Regulations Section 1.704-1(b), and shall be
interpreted and applied in a manner consistent with such Regulations. In the
event the Trustee shall determine that it is prudent to modify the manner in
which the Capital Accounts, or any debits or credits thereto (including,
without limitation, debits or credits relating to liabilities which are secured
by contributed or distributed property or which are assumed by the Trust, the
Trustee, or the Unitholders) are computed in order to comply with such
Regulations, the Trustee may make such modification without regard to Article 12
of the Agreement, provided that it is not likely to have a material effect on
                  -------- ----
the amounts distributable to any Person pursuant to Article 11 of the Agreement
upon the dissolution of the Trust. The Trustee also shall (i) make any
adjustments that are necessary or appropriate to maintain equality between the
Capital Accounts of the Unitholders and the amount of Trust capital reflected on
the Trust's balance sheet, as computed for book purposes, in accordance with
Regulations Section 1.704-1(b)(2)(iv)(q), and (ii) make any appropriate
modifications in the event unanticipated events might otherwise cause this
Agreement not to comply with Regulations Section l.704-1(b).

2.   No Interest
     -----------

     No interest shall be paid by the Trust on Capital Contributions or on
balances in Unitholders' Capital Accounts.

3.   No Withdrawal
     -------------

     No Unitholder shall be entitled to withdraw any part of its Capital
Contribution or his Capital Account or to receive any distribution from the
Trust, except as provided in Articles 2, 3 and 11 of the Agreement.

SPECIAL ALLOCATION RULES

1.   Special Allocation Rules.
     ------------------------

     Notwithstanding any other provision of the Agreement or this Exhibit B, the
                                                                  ---------
following special allocations shall be made in the following order:

     A. Minimum Gain Chargeback. Notwithstanding the provisions of Section 4.1
        -----------------------
of the Agreement or any other provisions of this Exhibit B, if there is a net
                                                 ---------
decrease in Trust Minimum Gain during any Fiscal Year, each Unitholder shall be
specially allocated items of Trust income and gain for such year (and, if
necessary, subsequent years) in an amount equal to such Unitholder's share of
the net decrease in Trust Minimum Gain, as determined under Regulations Section
1.704-2(g). Allocations pursuant to the previous sentence shall be made in
proportion to the respective amounts required to be allocated to each Unitholder
pursuant thereto. The items to be so allocated shall be determined in accordance
with Regulations Section 1.704-2(f) (6). This Section 1.A is intended to comply
with the minimum gain chargeback requirements in Regulations Section 1.704-2(f)
and for purposes of this Section 1.A only, each Unitholder's Adjusted Capital
Account Deficit shall be determined prior to any other allocations pursuant to
Section 4.1 of this Agreement with respect to such Fiscal Year and without
regard to any decrease in Unitholder Minimum Gain during such Fiscal Year.

     B. Unitholder Minimum Gain Chargeback. Notwithstanding any other provision
        ----------------------------------
of Section 4.1 of this Agreement or any other provisions of this Exhibit B
                                                                 ---------
(except Section 1.A hereof), if there is a net decrease in Unitholder Minimum
Gain attributable to a Unitholder Nonrecourse Debt during any Fiscal Year, each
Unitholder who has a share of the Unitholder Minimum Gain attributable to such
Unitholder Nonrecourse Debt, determined in accordance with Regulations Section
1.704-2(i) (5), shall be specially allocated items of Trust income and gain for
such year (and, if necessary, subsequent years) in an amount equal to such
Unitholder's share of the net decrease in Unitholder Minimum Gain attributable
to such Unitholder Nonrecourse Debt, determined in accordance with Regulations
Section 1.704-2(i) (5). Allocations pursuant to the previous sentence shall be
made in proportion to the respective amounts required to be allocated to each
Trustee and other Unitholder pursuant thereto. The items to be so allocated
shall be determined in accordance with Regulations Section 1.704-2(i) (4). This
Section 1.B is intended to comply with the minimum gain chargeback requirement
in such Section of the Regulations and shall be interpreted consistently
therewith. Solely for purposes of this Section 1.B, each Unitholder's Adjusted
Capital Account Deficit shall be determined prior to any other allocations
pursuant to Section 4.1 of the Agreement or this Exhibit with respect to such
Fiscal Year, other than allocations pursuant to Section 1.A hereof.

     C. Qualified Income Offset. In the event any Unitholder unexpectedly
        -----------------------
receives any adjustments, allocations or distributions described in Regulations
Sections 1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5), or
1.704-1(b)(2)(ii)(d)(6), and after giving effect to the allocations required
under Sections 1.A and 1.B hereof with respect to such Fiscal Year hereof, such
Unitholder has an Adjusted Capital Account Deficit, items of Trust income and
gain

                                        1

<PAGE>

(consisting of a pro rata portion of each item of Trust income, including gross
income and gain for the Fiscal Year) shall be specifically allocated to such
Unitholder in an amount and manner sufficient to eliminate, to the extent
required by the Regulations, its Adjusted Capital Account Deficit created by
such adjustments, allocations or distributions as quickly as possible. This
Section 1.C is intended to constitute a "qualified income offset" under
Regulations Section 1.704-1(b)(2)(ii)(d) and shall be interpreted consistently
therewith.

     D. Gross Income Allocation. In the event that any Unitholder has an
        -----------------------
Adjusted Capital Account Deficit at the end of any Fiscal Year (after taking
into account allocations to be made under the preceding paragraphs hereof with
respect to such Fiscal Year), each such Unitholder shall be specially allocated
items of Trust income and gain (consisting of a pro rata portion of each item of
Trust income, including gross income and gain for the Fiscal Year) in an amount
and manner sufficient to eliminate, to the extent required by the Regulations,
its Adjusted Capital Account Deficit.

     E. Nonrecourse Deductions. Nonrecourse Deductions for any Fiscal Year shall
        ----------------------
be allocated to the Unitholders in accordance with their respective Percentage
Interests. If the Trustee determines in its good faith discretion that the
Trust's Nonrecourse Deductions must be allocated in a different ratio to satisfy
the safe harbor requirements of the Regulations promulgated under Section 704(b)
of the Code, the Trustee is authorized, upon notice to the other Unitholders, to
revise the prescribed ratio for such Fiscal Year to the numerically closest
ratio which would satisfy such requirements.

     F. Unitholder Nonrecourse Deductions. Any Unitholder Nonrecourse Deductions
        ---------------------------------
for any Fiscal Year shall be specially allocated to the Unitholder who bears the
economic risk of loss with respect to the Unitholder Nonrecourse Debt to which
such Unitholder Nonrecourse Deductions are attributable in accordance with
Regulations Sections 1.704-2(b)(4) and 1.704-2(i).

     G. Code Section 754 Adjustments. To the extent an adjustment to the
        ----------------------------
adjusted tax basis of any Trust asset pursuant to Section 734(b) or 743(b) of
the Code is required, pursuant to Regulations Section 1.704-1(b)(2)(iv)(m), to
be taken into account in determining Capital Accounts, the amount of such
adjustment to the Capital Accounts shall be treated as an item of gain (if the
adjustment increases the basis of the asset) or loss (if the adjustment
decreases such basis), and such item of gain or loss shall be specially
allocated to the Unitholders in a manner consistent with Exhibit B and the
                                                         ---------
manner in which their Capital Accounts are required to be adjusted pursuant to
such Section of the Regulations.

2.   Allocations for Tax Purposes
     ----------------------------

     A. Except as otherwise provided in this Section 2, for federal income tax
purposes, each item of income, gain, loss and deduction shall be allocated among
the Unitholders in the same manner as its correlative item of "book" income,
gain, loss or deduction is allocated pursuant to Section 4.1 of the Agreement
and Section 1 of this Exhibit B.
                      ---------

                                        2

<PAGE>

     B.   In an attempt to eliminate Book-Tax Disparities attributable to a
Contributed Property or Adjusted Property, items of income, gain, loss, and
deduction shall be allocated for federal income tax purposes among the
Unitholders as follows:

          (1)  (a)  In the case of a Contributed Property, such items
                    attributable thereto shall be allocated among the
                    Unitholders consistent with the principles of Section 704(c)
                    of the Code to take into account the variation between the
                    704(c) Value of such property and its adjusted basis at the
                    time of contribution (taking into account Section 2.C of
                    this Exhibit B; and
                         ---------

               (b)  any item of Residual Gain or Residual Loss attributable to
                    a Contributed Property shall be allocated among the
                    Unitholders in the same manner as its correlative item of
                    "book" gain or loss is allocated pursuant to Section 4.1 of
                    the Agreement and Section 1 of this Exhibit B.
                                                        ---------

          (2)  (a)  In the case of an Adjusted Property, such items shall

                    (1) first, be allocated among the Unitholders in a manner
                    consistent with the principles of Section 704(c) of the Code
                    to take into account the Unrealized Gain or Unrealized Loss
                    attributable to such property and the allocations thereof
                    pursuant to Exhibit A, and
                                ---------

                    (2) second, in the event such property was originally a
                    Contributed Property, be allocated among the Unitholders in
                    a manner consistent with Section 2.B(1) of this Exhibit B;
                                                                    ---------
                    and

               (b)  any item of Residual Gain or Residual Loss attributable to
                    an Adjusted Property shall be allocated among the
                    Unitholders in the same manner as its correlative item of
                    "book" gain or loss is allocated pursuant to Section 4.1 of
                    the Agreement and Section 1 of this Exhibit B.
                                                        ---------

          (3)  all other items of income, gain, loss and deduction shall be
               allocated among the Unitholders in the same manner as their
               correlative item of "book" gain or loss is allocated pursuant to
               Section 4.1 of the Agreement and Section 1 of this Exhibit B.
                                                                  ---------

     C.   To the extent Treasury Regulations promulgated pursuant to Section
704(c) of the Code permit a partnership to utilize alternative methods to
eliminate the disparities between the Carrying Value of property and its
adjusted basis, the Trustee shall, subject to the following, have the authority
to elect the method to be used by the Trust and such election shall be binding
on all Unitholders provided that, to the extent that the Trustee has agreed to
                   -------- ----
use a particular method

                                        3

with respect to a Contributed Property, the Trustee shall be bound by such
agreement (including, without limitation, the agreements set forth in Exhibit C
                                                                      ---------

          Background
          ----------

Partnership (the "Merger Agreement") (the "SRW Merger"), the Trust is making
certain undertakings to the former limited partners of SRW Partnership who
became Unitholders of the Trust as a result of the SRW Merger (the "Former SRW
Limited Partners"). The specific agreements between the Trust and SRW
Partnership with respect to these various matters are described below.

          Specific Agreements
          -------------------

based upon the number of days in such Fiscal Year following the SRW Merger
divided by 365 and (ii) with respect to a Protected Unit that ceases to be a

secured by any of the Protected Properties (or is treated for purposes of
Treasury Regulation (S) 1.752-3(a)(2) as secured by any of the Protected
Properties, determined taking into account the IRS Private Letter Ruling). The

          IRS Private Letter Ruling: The ruling received by the SRW Partnership
          -------------------------
from the Internal Revenue Service dated November 6, 1997.

          Protected Units: Means only those Units issued to the SRW Partners in
          ---------------
connection with the SRW Merger, or any Units thereafter issued by the Trust to
the SRW Partners in exchange for such Protected Units or with respect to such
Protected Units. The term Protected Units shall not include any other Units
hereafter acquired by an SRW Partner, whether from the Trust or otherwise.

          Protected Properties: Means, except as otherwise specifically provided
          --------------------
in this Exhibit D, only those properties and assets set forth on Schedule 2 to
                                                                 ----------
this Exhibit D and any other properties or assets hereafter acquired by the
Trust received as "substituted basis property" as defined in Section 7701(a)(42)
of the Code with respect to such Protected Properties.

          Protected Period: Means the period ending at 12:01 A.M. on January 1,
          ----------------
2022.

          SRW Partners: Means the Former SRW Limited Partners, other than SRW
          ------------
and the Trustee as a successor to SRW, and any Person who holds Protected Units
who acquires such Protected Units from an SRW Partner in a transaction in which
gain or loss is not recognized in whole for federal income tax purposes and in
which such transferee's adjusted basis, as determined for federal income tax
purposes, is determined in whole or in part by reference to the adjusted basis
of the SRW Partner in such Protected Units. A tentative list of such partners is
set forth on Schedule 1 to this Exhibit D and shall be updated by the Trustee
prior to the closing of the SRW Merger to accurately reflect the names of the
Persons who acquire Protected Units in the SRW Merger.

          Subsidiary: Means any partnership, limited liability company, trust or
          ----------
other entity whose disposition of a Protected Property or any direct or indirect
interest therein would result in the allocation of taxable gain to one or more
SRW Partners pursuant to Section 704(c) of the Code and the Treasury Regulations
thereunder.

          2.  Restrictions on Dispositions of Protected Properties.

          (a) The Trust agrees for the benefit of each SRW Partner, for the term
of the Protected Period, not to directly or indirectly sell, exchange, transfer,
or otherwise dispose of any Protected Property or any interest therein (without
regard to whether such disposition is voluntary or involuntary) to the extent
that such disposition would cause an SRW Partner to recognize part or all of the
gain that would have been recognized for federal income tax purposes upon a
fully taxable disposition of one or more Protected Properties at the time of the
SRW Merger. Without limiting the foregoing, the term "sale, exchange, transfer
or disposition" by the Trust shall be deemed to include, and the prohibition
shall extend to, (i) any disposition by any Subsidiary of the Trust of any
Protected Property or any interest therein, and (ii) any direct or indirect
disposition by the

                                       D-2

<PAGE>

Trust or any Subsidiary of the Trust of all or any portion of its interest in
any entity that was a subsidiary of the SRW Partnership (which shall include,
without limitation, any transaction involving a distribution or deemed
distribution by a Subsidiary to the Trust under Section 731 of the Code) to the
extent that such disposition would cause an SRW Partner to recognize part or all
of the gain that would have been recognized for federal income tax purposes upon
a fully taxable disposition of one or more Protected Properties at the time of
the SRW Merger. Notwithstanding the foregoing, a disposition by a Subsidiary of
a Protected Property will not violate this Section 2(a) if (but only if)
immediately prior to the closing of the SRW Merger, an owner of an interest in
such Subsidiary that is not an Affiliate of SRW Partnership or SRW had (or would
have had in the future) the ability to cause such Subsidiary to effect such
disposition of such Protected Property notwithstanding the objection of, or
without the consent of, the SRW Partnership, provided that such ability will not
                                             -------------
be considered to exist if under the applicable operative legal documents
relating to the organization and operation of the Subsidiary or any other
agreement or arrangement between the parties, the SRW Partnership or one of its
Subsidiaries would have been able to take an action that would have been
effective to prevent the recognition of gain with respect to the Protected
Property, including, without limitation, a "right of first refusal" or "first
offer" as to either the Protected Property or the outside investor's interest in
the Subsidiary, or a "buy-sell" or similar arrangement as to either the
Protected Property or the outside investor's interest in the Subsidiary. Without
limiting the foregoing, a disposition shall include any transfer, voluntary or
involuntary, in a foreclosure proceeding, pursuant to a deed in lieu of
foreclosure, or in a bankruptcy proceeding.

               (b)  Notwithstanding the restriction set forth in Section 2(a),
the Trust (or any Subsidiary) may dispose of a Protected Property if such
disposition qualifies as a like-kind exchange under Section 1031 of the Code, or
an involuntary conversion under Section 1033 of the Code, or other transaction
(including, but not limited to, a contribution of property to any entity that
qualifies for the nonrecognition of gain under Section 721 or Section 351 of the
Code, or a merger or consolidation of the Trust with or into another entity that
qualifies for taxation as a "partnership" for federal income tax purposes (a
"Successor Partnership")) that does not result in the recognition of any taxable
income or gain to an SRW Partner with respect to any of the Protected Units;
provided, however, that: (1) in the event of a disposition under Section 1031 or
--------  -------
Section 1033 of the Code, any property that is acquired in exchange for or as a
replacement for a Protected Property shall thereafter be considered a Protected
Property for purposes of this Section 2; (2) in the case of a Section 1031
like-kind exchange, if such exchange is with a "related party" within the
meaning of Section 1031(f)(3) of the Code, any direct or indirect disposition by
such related party of the Protected Property or any other transaction prior to
the expiration of the two (2) year period following such exchange that would
cause Section 1031(f)(1) to apply with respect to the Protected Property
(including by reason of the application of Section 1031(f)(4)) shall be
considered a violation of Section 2(a) by the Trust; (3) if the Protected
Property is transferred to another entity in a transaction in which gain or loss
is not recognized, the interest of the Trust in such entity shall thereafter be
considered a Protected Property for purposes of this Section 2, and if the
acquiring entity's disposition of the Protected Property would cause an SRW
Partner to recognize gain or loss as a result thereof, the transferred Protected
Property still shall be considered a Protected Property for purposes of this
Section 2 and the transferee shall have agreed to be jointly and severally
liable for any payments required under Section 2(c) hereof; and (4) in the event
of a merger

                                       D-3

<PAGE>

or consolidation involving the Trust and a Successor Partnership, the Successor
Partnership shall have agreed in writing for the benefit of the SRW Partners
that all of the restrictions of this Section 2 shall apply with respect to the
Protected Properties.

          (c)  Any merger or consolidation involving the Trust or any Subsidiary
of the Trust, whether or not the Trust is the surviving entity in such merger or
consolidation, that results in an SRW Partner being required to recognize part
or all of the gain that would have been recognized for federal income tax
purposes upon a fully taxable disposition of one or more Protected Properties at
the time of the SRW Merger shall be deemed to be a disposition of the Protected
Properties for purposes of Section 2(a).

          3.   Prohibition on Repayment or Prepayment of Existing Nonrecourse
Debt.

          (a)  Except as otherwise expressly permitted in this Section, during
the term of the Protected Period, the Trust shall not, directly or indirectly,
cause or permit the Trust or any Subsidiary to repay or prepay any of the
Existing Nonrecourse Debt.

          (b)  (i)  Without limiting Section 3(a), the Trust shall cause each
Existing Nonrecourse Debt that is identified on Schedule 4-1 to this Exhibit D
                                                ------------
as qualifying as a Nonrecourse Liability allocable to one or more specified
Protected Properties immediately prior to the time of the Merger to qualify
throughout the term of the Protected Period as (i) a "nonrecourse liability" (as
defined in Treasury Regulation (S) 1.752-1(a)(2)) (a "Nonrecourse Liability")
that is allocable to those specified Protected Properties for purposes of
Treasury Regulation (S) 1.752-3(a) and (ii) "qualified nonrecourse financing"
(as defined in Section 465(b)(6)(B) of the Code) ("Qualified Nonrecourse
Financing") allocable to the applicable Protected Properties, except to the
extent that the failure to so qualify is a result of any action taken by any SRW
Partner or any affiliate of an SRW Partner, unless such action requires the
consent or assistance of the Trust or Trustee and the Trust or Trustee granted
such consent or provided such assistance, including without limitation, any such
SRW Partner or any of their affiliates being or becoming the lender or otherwise
considered to "bear the economic risk of loss" (within the meaning of Treasury
Regulation (S) 1.752-2) with respect to such Existing Nonrecourse Debt or any
Replacement Debt. In determining whether the requirements of this Section
3(b)(i) are met as to an Existing Nonrecourse Debt, the Trust shall be entitled
to assume that immediately following the SRW Merger such Existing Nonrecourse
Debt is considered to be a Nonrecourse Liability and Qualified Nonrecourse
Financing allocable to those specified Protected Properties in the amounts set
forth on Schedule 4-1 to this Exhibit D at the time of the Merger, and the Trust
         ------------
shall be entitled to rely on the IRS Private Letter Ruling.

               (ii) Without limiting Section 3(a), the Trust shall cause each
Existing Nonrecourse Debt that is identified on Schedule 4-2 to this Exhibit D
                                                ------------
as qualifying as a Partner Nonrecourse Debt allocable to one or more specified
SRW Partners immediately prior to the time of the Merger to qualify throughout
the term of the Protected Period as (i) a "partner nonrecourse debt" as defined
in Treasury Regulation (S). 1.704-2(b)(4) (a "Partner Nonrecourse Debt") that is
allocable to those specified SRW Partners for purposes of Treasury Regulation
(S) 1.752-2(a) and (ii) a debt for which those specified SRW Partners are
considered "at risk" for purposes of Section 465(b) of the Code ("At Risk
Indebtedness"),

                                       D-4

<PAGE>

except to the extent that the failure to so qualify is a result of any action
taken by any SRW Partner or any affiliate of an SRW Partner, unless such action
requires the consent or assistance of the Trust or Trustee and the Trust or
Trustee granted such consent or provided such assistance, including without
limitation, any such SRW Partner or any of their affiliates being or becoming
the lender or otherwise considered to "bear the economic risk of loss" (within
the meaning of Treasury Regulation (S) 1.752-2) with respect to such Existing
Nonrecourse Debt or any Replacement Debt. In determining whether the
requirements of this Section 3(b)(ii) are met as to an Existing Nonrecourse
Debt, the Trust shall be entitled to assume that immediately following the SRW
Merger such Existing Nonrecourse Debt is considered a Partner Nonrecourse Debt
and At Risk Indebtedness at the time of the Merger allocable to the specified
SRW Partners in the amounts set forth on Schedule 4-2 to this Exhibit D.
                                         ------------

          (c)  The requirements in Section 3(a) and Section 3(b) above shall not
apply in the case of:

               (i)  a payment or repayment that consists solely of a required
principal amortization payment made with respect to an Existing Nonrecourse Debt
or Replacement Debt (as defined in clause (ii) below) in accordance with the
principal amortization schedules in effect at the effective time of the SRW
Merger with respect to such Existing Nonrecourse Debt (or in the case of
Replacement Debt, a principal amortization schedule that meets the conditions
set forth in subclause (z) of clause (ii) below; provided that a required
                                                 -------------
payment of principal at the scheduled maturity of any indebtedness shall not be
considered within the scope of this clause (i) (and, accordingly, the Trust
shall be required to refinance such maturing indebtedness with debt that would
be considered qualifying Replacement Debt under clause (ii) below); or

               (ii) a payment of principal made from proceeds of new
indebtedness incurred to refinance Existing Nonrecourse Debt (such new
indebtedness incurred pursuant to the refinancing that meets the conditions set
forth below in this clause (ii) is referred to in this Agreement as "Replacement
Debt"), provided that (x) such refinancing is made on a basis that the
        -------- ----
Replacement Debt would meet the requirements of Section 3(b)(i) or Section
3(b)(ii), as applicable (assuming in the case of Existing Nonrecourse Debt or
Replacement Debt subject to Section 3(b)(ii) that the affected SRW Partners
execute guarantees of such Replacement Debt in such form as may be requested by
the Trust and/or the applicable lender, subject to the condition that such debt
have collateral that has a value (as determined in good faith by the Trustee)
that is not less than the value (as determined in good faith by the Trustee) of
the collateral for the Existing Nonrecourse Debt or Replacement Debt being
refinanced and that the guarantee arrangement meets the criteria set forth in
Section 3(g) for an "acceptable guarantee"; (y) that the principal amount of the
Replacement Debt is at least equal to the principal amount of the Existing
Nonrecourse Debt on the date of such refinancing; and (z) (I) with respect to
the refinancing of an Existing Nonrecourse Debt, provides either for
"interest-only" payments or for level payments of principal and interest that
would not result in amortization of the remaining principal balance over a
period shorter than twenty-five years (plus, if the Existing Nonrecourse Debt to
be refinanced is being refinanced prior to maturity, the number of years
remaining to its maturity); and (II) with respect to the refinancing of
Replacement Debt previously incurred to refinance an Existing Nonrecourse

                                       D-5

<PAGE>

Debt, provides either for "interest-only" payments or for level payments of
principal and interest that would not result in amortization of the remaining
principal balance of the new Replacement Debt over a period shorter than
twenty-five years (plus the number of years referred to in the preceding
parenthetical for the Replacement Debt being refinanced, less the number of
years of permitted principal amortization that have occurred with respect to the
Replacement Debt being refinanced).

          (d)   For the purposes of this Section 3, any transaction or other
event, including, without limitation, any modification of indebtedness, in which
any Unitholder or any affiliate of any such Unitholder would become personally
liable for, or would bear or incur, directly or indirectly, the "risk of loss"
with respect to any Existing Nonrecourse Debt or any Replacement Debt that
either (i) would cause such Debt not to be considered a Nonrecourse Liability or
Qualified Nonrecourse Financing (except to the extent such Existing Nonrecourse
Debt and any Replacement Debt with respect thereto is described in Section
3(b)(ii)) or (ii) if such Existing Nonrecourse Debt is described in Section
3(b)(ii), would cause the amount of such Debt that is considered Partner
Recourse Debt or At Risk Indebtedness with respect to any SRW Partner to be
reduced, shall be considered a refinancing of such Debt and shall be subject to
the requirements set forth in this Section 3, except to the extent that the
failure to so qualify is a result of any action taken by any SRW Partner or any
affiliate of an SRW Partner, unless such action requires the consent or
assistance of the Trust or Trustee and the Trust or Trustee granted such consent
or provided such assistance, including without limitation, any such SRW Partner
or any of their affiliates being or becoming the lender or otherwise considered
to "bear the economic risk of loss" (within the meaning of Treasury Regulation
ss. 1.752-2) with respect to such Existing Nonrecourse Debt or any Replacement
Debt.

          (e)   For the purposes of this Section 3, any sale, exchange or other
disposition (including an exchange to which Section 1031 or 1033 of the Code
applies) of a property that is subject to an Existing Nonrecourse Debt or
Replacement Debt shall be considered a repayment of such Debt and shall be
subject to the provisions of this Section 3, unless in connection with such
sale, exchange or other disposition, (i) the Trust incurs Replacement Debt that
would meet the requirements of Section 3(b)(i) or (b)(ii), as applicable, in an
amount equal to the amount of Debt that is considered to be a refinancing under
this Section 3(e) and (ii) the SRW Partners who were pursuant to the Treasury
Regulations under Section 752 of the Code allocated a share of the Existing
Nonrecourse Debt or Replacement Debt considered repaid would be allocated at all
times necessary to avoid any deemed distribution of cash to any of the SRW
Partners under Section 731 of the Code an amount of the new Replacement Debt
that is at least equal to such amount previously allocated to them.

          (f)   If an Existing Nonrecourse Debt or Replacement Debt shall mature
during the term of the Protection Period, the Trust shall, prior to the stated
maturity of the Existing Nonrecourse Debt or Replacement Debt (the "Maturing
Debt"), cause the Trust to refinance the Maturing Debt with Replacement Debt
that (i) would meet the requirements of Section 3(b)(i) or Section 3(b)(ii), as
applicable (assuming in the case of Existing Nonrecourse Debt or Replacement
Debt subject to Section 3(b)(ii) that the affected SRW Partners execute
guarantees of such Replacement Debt in such form as may be requested by the
Trust and/or the applicable lender, subject to the condition that such debt have

collateral that has a value (as determined in good faith by the Trustee) that is
not less than the value (as determined in good faith by the Trustee) of the
collateral for the Existing Nonrecourse Debt or Replacement Debt being
refinanced and that the guarantee meets the criteria set forth in Section 3(g)
for an "acceptable guarantee", (ii) that would have a principal amount not less
than the principal amount of the Existing Nonrecourse Debt on the date of the
refinancing; and (iii) (x) with respect to the refinancing of an Existing
Nonrecourse Debt, provides either for "interest-only" payments or for level
payments of principal and interest that would not result in amortization of the
remaining principal balance over a period shorter than twenty-five years (plus,
if the Existing Nonrecourse Debt to be refinanced is being refinanced prior to
maturity, the number of years remaining to its maturity); and (y) with respect
to the refinancing of Replacement Debt previously incurred to refinance an
Existing Nonrecourse Debt, provides either for "interest-only" payments or for
level payments of principal and interest that would not result in amortization
of the remaining principal balance of the new Replacement Debt over a period
shorter than twenty-five years (plus the number of years referred to in the
preceding parenthetical for the Replacement Debt being refinanced, less the
number of years of permitted principal amortization that have occurred with
respect to the Replacement Debt being refinanced).

          (g)   For purposes of Section 3(c)(ii) and Section 3(f), a guarantee
is an "acceptable guarantee" if it meets the following criteria: (1) the
guarantee agreement is substantially in the form of the guarantee agreement that
the SRW Partner had in effect with respect to the Partner Nonrecourse Debt that
is being refinanced, with such changes that may be required by the lender and
that do not have the effect of reducing the economic and legal exposure of the
guarantor under the guarantee agreement; (2) the guarantee must be given as
consideration to a lender in connection with the making of a new loan or in
connection with the refinancing, extension or other material modification
favorable to the borrower of an existing loan; (3) the guarantee must be
executed and delivered to the lender, (4) the aggregate amount of guarantees,
indemnities and other similar undertakings made with respect to the applicable
debt must not exceed the face amount of the debt, and (5) as to each SRW Partner
that is executing a guarantee pursuant hereto, there must be no other Person
that would be considered to "bear the economic risk of loss," within the meaning
of Treasury Regulation (S) 1.752-2, or would be considered to be "at risk" for
purposes of Section 465(b) with respect to that portion of such debt for which
such SRW Partner is being made liable for purposes of satisfying the Trust's
obligations to such SRW Partner under Section 3(c)(ii) and Section 3(f).

               4.   Remedies for Breach.

               (a)  In the event that the Trust breaches its obligations set
forth in Section 2, Section 3, Section 6, Section 7 or Section 9 with respect to
an SRW Partner during the Protected Period, the SRW Partner's sole right shall
be to receive from the Trust, and the Trust shall pay to such SRW Partner as
damages, an amount equal to the aggregate federal, state and local income taxes
incurred by the SRW Partner as a result of the income or gain actually
recognized by such SRW Partner with respect to its Protected Units (after giving
effect to adjustments pursuant to Section 754 of the Code) by reason of such
breach, plus an amount equal to the aggregate federal, state, and local income
taxes payable by the SRW Partner as a result of the receipt of any payment
required under this Section 4(a). For purposes of computing the amount of
federal, state, and local income taxes required to be paid by an SRW Partner,
(i) any deduction allowed in computing federal income taxes for state income
taxes payable as a result thereof shall be taken into account, and (ii) an SRW
Partner's tax liability shall be computed using the highest federal, state and
local marginal income tax rates that would be applicable to such SRW Partner's
taxable income (taking into account the character of such income or gain) for
the year with respect to which the taxes must be paid, without regard to any
deductions, losses or credits that may be available to such SRW Partner that
would reduce or offset its actual taxable income or actual tax liability if such
deductions, losses or credits could be utilized by the SRW Partner to offset
other income, gain or taxes of the SRW Partner, either in the current year, in
earlier years, or in later years). In the event that an SRW Partner shall
acquire any additional Units subsequent to the SRW Merger by reason of a
contribution of additional money or property to the Trust, the income and gain
that shall be taken into account for purposes of computing the damages payable
under this Section 4(a) would not exceed the gain that such SRW Partner would
have recognized by reason of the Trust's breach of its obligation set forth in
Section 2, Section 3, Section 6, Section 7 or Section 9, as applicable, had such
SRW Partner not acquired such additional Units. In addition, in the case of a
breach of Section 2, in no event shall the gain taken into account for purposes
of computing the damages payable under this Section 4(a) exceed the amount of
gain that would have been recognized by the SRW Partner with respect to the
Protected Units if the Trust had sold the Protected Property in a fully taxable
transaction on the day following the closing of the SRW Merger for a purchase
price equal to the 704(c) Value of such Protected Property.

               (b)  Notwithstanding any provision of this Exhibit D, the sole
and exclusive rights and remedies of any SRW Partner for a breach or violation
of the covenants set forth in Section 2 or Section 3 shall be a claim for
damages against the Trust, computed as set forth in Section 4(a), and no SRW
Partner shall be entitled to pursue a claim for specific performance of the
covenant set forth in Section 2 or Section 3 or bring a claim against any Person
that acquires a Protected Property from the Trust in violation of Section 2
(other than a Successor Partnership that has agreed in writing to be bound by
the terms of this Exhibit D or that has otherwise succeeded to all of the assets
and all of the liabilities of the Trust, but then only for damages computed as
set forth in Section 4(a)). If the Trust has breached or violated any of the
covenants set forth in Section 2, Section 3, Section 6, Section 7 or Section 9
(or an SRW Partner asserts that the Trust has breached or violated any of the
covenants set forth in Section 2, Section 3, Section 6, Section 7 or Section 9,
the Trust and the SRW Partner agree to negotiate in good faith to resolve any

                                       D-8

<PAGE>

disagreements regarding any such breach or violation and the amount of damages,
if any, payable to such SRW Partner under Section 4(a). If any such disagreement
cannot be resolved by the Trust and such SRW Partner within sixty (60) days
after the receipt of notice from the Trust of such breach and the amount of
income to be recognized by reason thereof, the Trust and the SRW Partner shall
jointly retain a nationally recognized independent public accounting firm ("an
Accounting Firm") to act as an arbitrator to resolve as expeditiously as
possible all points of any such disagreement (including, without limitation,
whether a breach of any of the covenants set forth Section 2, Section 3, Section
6, Section 7 or Section 9 has occurred and, if so, the amount of damages to
which the SRW Partner is entitled as a result thereof, determined as set forth
in Section 4(a)). All determinations made by the Accounting Firm with respect to
the resolution of any breach or violation of any of the covenants set forth in
Section 2, Section 3, Section 6, Section 7 or Section 9 and the amount of
damages payable to the SRW Partner under Section 4(a) shall be final, conclusive
and binding on the Trust and the SRW Partner. The fees and expenses of any
Accounting Firm incurred in connection with any such determination shall be
shared equally by Trust and the SRW Partner, provided that if the amount
                                             -------- ----
determined by the Accounting Firm to be owed by the Trust to the SRW Partner is
not less than ninety percent (90%) of the amount asserted by the SRW Partner to
be owed, then all of the fees and expenses of any Accounting Firm incurred in
connection with any such determination shall be paid by the Trust. (The
exception in the proviso in the preceding sentence shall not apply to Robert H.
                 -------
Smith, Robert P. Kogod, members of their respective Immediate Families, and
entities that are Affiliates of Robert H Smith, Robert P. Kogod, and/or members
of their respective Immediate Families.)

               (c)   For purposes of this Section 4, if any SRW Partner is, for
federal income tax purposes, a partnership, an S corporation, "real estate
investment trust" or a trust, then all computations of amounts of taxes required
to be paid by the SRW Partner and the payments due from the Trust as a result
thereof shall be made by computing the taxes required to be paid by the
partners, shareholders or beneficiaries of such partnership, S corporation,
"real estate investment trust" or trust (or to the extent that any partner,
shareholder or beneficiary of such partnership S corporation or trust is itself
a partnership, S corporation or trust, the same principles shall apply in
determining the taxes required to be paid by such partner, shareholder or
beneficiary).

               (d)   In the event that there has been a breach of Section 2,
Section 3, Section 6, or Section 7, the Trustee shall provide to the SRW Partner
notice of the transaction or event giving rise to such breach not later than at
such time as the Trustee provides to the SRW Partners the Schedule K-1's to the
Trust's federal income tax return as required in accordance with Section 8.1 of
Annex A of the Declaration of Trust. All payments required under this Section 4
to any SRW Partner shall be made to such SRW Partner not later than seven (7)
days after receipt by the Trust of a written claim from such SRW Partner
therefor, unless the Trust disagrees with the computation of the amount required
to be paid in respect of such breach, in which event the procedures in Section
4(b) shall apply and the payment shall be due within seven (7) days after the
earlier of a determination by the Accounting Firm or an agreement between the
Trust and the SRW Partner as to the amount required to be paid, with interest
accruing on the aggregate amount required to be paid from the date that is seven
(7) days after receipt by the Trust of a claim from such SRW Partner to the date
of actual payment at a rate equal to the "prime

                                       D-9

<PAGE>

rate" of interest, as published in the Wall Street Journal (or if no longer
published there, as announced by Citibank) effective as of the date the payment
is required to be made.

               5.   Opportunity for SRW Partners to Enter into Deficit
Restoration Obligations. Without limiting any of the obligations of the Trust
under this Agreement, the Trust shall consider in good faith a request by an SRW
Partner to enter into an agreement with the Trust to bear the economic risk of
loss as to a portion of the Trust's recourse indebtedness by undertaking an
obligation to restore a portion of its negative capital account balance upon
liquidation of such SRW Partner's interest in the Trust, if such SRW Partner
shall provide information from its professional tax advisor satisfactory to the
Trust showing that, in the absence of such agreement, such SRW Partner likely
would not be allocated from the Trust sufficient indebtedness under Section 752
of the Code and the at-risk provisions under Section 465 of the Code to avoid
the recognition of gain (other than gain required to be recognized by reason of
actual cash distributions from the Trust). The Trust and its professional tax
advisors shall cooperate in good faith with such SRW Partner and its
professional tax advisors to provide such information regarding the allocation
of the Trust liabilities and the nature of such liabilities as is reasonably
necessary in order to determine the SRW Partner's adjusted tax basis in its
Units and at-risk amount. In deciding whether or not to grant such a request,
the Trust shall be entitled to take into account all factors related to the
Trust, including, without limitation, the existing and anticipated debt
structure of the Trust, the tax situations of all other Unitholders, including
the Trustee (individually and as a group), and the effect that granting such a
request might have on their tax situation, and the anticipated long-term
business needs of the Trust. The Trust's only obligation with respect to any
such request from an SRW Partner pursuant to this Section 5 shall be to act in
good faith. In the event the Trust fails to act in good faith with respect to
any such request, the exclusive remedy of the SRW Partner who made such request
shall be an action for specific performance, with no entitlement to monetary
damages.

          6.   Section 708 Termination; Section 704(c) Method.

               (a)   The Trust shall treat the merger of SRW into the Trustee as
a transfer of a greater than fifty percent (50%) interest in the capital and
profits of SRW Partnership that resulted in a termination of SRW Partnership
pursuant to Section 708(b)(1)(B) of the Code at the effective time of the merger
of SRW into the Trustee.

               (b)   Notwithstanding Paragraph 2.C of Exhibit C to Annex A of
                                                      ---------
the Declaration of Trust, the Trust shall use the "traditional method" under
Regulations ss. 1.704-3(b) for purposes of making allocations under Section
704(c) of the Code (with no "curative allocations" to offset the effect of a
"Ceiling Rule Disparity" as described in Section 6(c) below, except as set forth
in Section 6(d) below) with respect to (i) each of the assets acquired by the
Trust from the SRW Partnership in the SRW Merger (including, without limitation,
all assets owned by any direct or indirect Subsidiaries of the SRW Partnership
that are treated either as a partnership or as a disregarded entity for federal
income tax purposes), except to the extent that the Trust expressly would be
required to use a different method under a SRW Tax Protection Agreement assumed
by the Trust pursuant to the Merger Agreement and the affected SRW Partner has
not executed an agreement to waive its right to such different method following
the SRW Merger, and (ii) with respect to each of

                                       D-10

<PAGE>

the other assets acquired by the Trust or deemed acquired by the Trust from the
Trustee or its Affiliates in connection with the SRW Merger. The 704(c) Values
of the Protected Properties shall be as determined by the Trustee in good faith
for purposes of preparing the financial statements of the Trust and the Trustee
reflecting the results of the SRW Merger provided that Robert H. Smith and
Robert P. Kogod, as representatives for the Protected Partners, shall have the
opportunity to review and comment on the 704(c) Values. The Trustee shall
consider in good faith such revisions as are reasonably requested by Messrs.
Smith and Kogod; provided that, after considering in good faith any such
reasonable requests, the Trustee shall have the sole and absolute discretion to
determine in good faith the 704(c) Values. Notwithstanding the foregoing, the
704(c) Values of the stock and securities of (including debt outstanding to)
Consolidated Engineering Services, Inc. that are being acquired by Trust shall
not exceed $106 million and the value of the stock and securities of (including
debt outstanding to) Smith Management Construction, Inc. that are being acquired
by Trust shall not exceed $10 million. The Trust shall, for purposes of Treasury
Regulations (S)(S) 1.704-3 and 1.704-1(b)(2)(iv)(g)(3), elect to use a 27 1/2
year useful life with respect to any property constituting "residential real
property" within the meaning of Section 168(c) of the Code that is part of the
Protected Properties, except where such a useful life is not permitted under the
Code.

          (c) For purposes of Section 6(b) and Section 6(d), the term "Ceiling
Rule Disparity" shall mean the excess, if any, of (i) the aggregate amount of
Depreciation with respect to any asset allocated to the "non-contributing
partners" (that is, the holders of Units who are not subject to Section 704(c)
of the Code and Treasury Regulations (S) 1.704-3 with respect to such asset),
over (ii) the aggregate amount of depreciation deductions with respect to such
asset allocated to the "non-contributing partners" for federal income tax
purposes from the Effective Date to the date of the disposition of such asset.

          (d) In order to offset the effect of Ceiling Rule Disparities, the
Trust shall make the Curative Allocation with respect to each Protected Unit
each Fiscal Year, which Curative Allocation shall be considered to offset first
any Ceiling Rule Disparities that exist with respect to a Protected Unit that
are attributable to appreciation in the Protected Properties and depreciation
claimed with respect to the Protected Properties that is attributable to periods
after the Protected Properties were acquired by SRW Partnership, and only after
all such Ceiling Rule Disparities have been eliminated with respect to a
particular SRW Partner would such allocation be considered to offset any Ceiling
Rule Disparities that exist with respect to a Protected Unit that are
attributable to appreciation in the Protected Properties and depreciation
claimed with respect to the Protected Properties that is attributable to periods
before the Protected Properties (or the applicable predecessor properties) were
acquired by SRW Partnership. To the extent that the Curative Allocation is not
sufficient to eliminate the effect of all Ceiling Rule Disparities with respect
to a particular Protected Property, the Trust shall make a "curative allocation"
upon a disposition of that particular Protected Property to offset the remaining
balance, if any, of the Ceiling Rule Disparity with respect to that particular
Protected Property.

     7.   Allocations of Liabilities Pursuant to Regulations Under Section 752.
All tax returns prepared by the Trust during the Protected Period shall allocate
liabilities of

                                       D-11

<PAGE>

the Trust for purposes of Section 752 and the Treasury Regulations thereunder
taking into account the following:

          (i)   for purposes of allocating any Existing Nonrecourse Debt or
Replacement Debt that is identified on Schedule 4-1 as a Nonrecourse Liability,
                                       ------------
the Trust, for purposes of Treasury Regulations (S)(S) 752-3(a)(2) and
1.752-3(a)(3), shall treat such Existing Nonrecourse Debt (or any Replacement
Debt therefor) as allocable to those specified Protected Properties in amounts
not less than the amounts set forth on Schedule 4-1 to this Exhibit D at the
                                       ------------
time of the SRW Merger (subject to reduction as and to the extent permitted
under Section 3), and, absent a change to the Code or the Treasury Regulations,
the Trust shall follow the methodology set forth in the IRS Private Letter
Ruling;.

          (ii)  the Trust shall allocate any Existing Nonrecourse Debt or
Replacement Debt that constitutes "excess nonrecourse liabilities" of the Trust
to the SRW Partners in the manner set forth in sentence five of Treasury
Regulations (S) 1.752-3(a)(3) following the SRW Merger;

          (iii) the Trust shall allocate to each SRW Partner who is shown on
Schedule 4-2 to this Exhibit D as having liability for a specified dollar amount
------------
of an Existing Nonrecourse Debt that is a Partner Nonrecourse Debt a dollar
amount of such Partner Nonrecourse Debt equal to the amount shown on Schedule
                                                                     --------
4-2 with respect to such SRW Partner (subject to reduction as and to the extent
----
permitted under Section 3); and

          (iv)  in making allocations of debt under Treasury Regulation (S)
1.752-3(a)(2) with respect to a specific Protected Property, the Trust shall
make an allocation (I) first to the SRW Partners in an amount equal to the
lesser of (x) the "Section 704(c) minimum gain" that such SRW Partner would have
been allocated by SRW Partnership under Treasury Regulation (S) 1.752-3(a)(2)
immediately prior to the SRW Merger or (y) the "Section 704(c) minimum gain"
that such SRW Partner would have been allocated by SRW Partnership under
Treasury Regulation (S) 1.752-3(a)(2) immediately after such SRW Partner
acquired an interest in SRW Partnership by reason of the contribution of an
interest in the Protected Property (or a predecessor asset) to SRW Partnership
in exchange for an interest in SRW Partnership, and (II) thereafter pro rata
among the SRW Partners based upon the number of Protected Units that they hold
and their proportionate shares of the "Section 704(c) minimum gain" existing
immediately after the SRW Merger in excess of the amounts described in (y).

In addition, the Trust shall not make available after the date of the SRW
Merger, whether pursuant to an agreement entered into after such date or
otherwise, to any other Unitholder a method of allocating "excess nonrecourse
liabilities" of the Trust that is more favorable than that made available to
such SRW Partners without making such method available to the SRW Partners on a
pro rata basis with such other Unitholders.

          Notwithstanding the provision of this Exhibit D, the Trust shall not
be required to make allocations of Nonrecourse Liabilities or Partner
Nonrecourse Debt to the SRW Partners as set forth in this Exhibit D if and to
the extent that, as a result of a change in Section 752 of the Code or the
Treasury Regulations occurring after the date hereof, the

                                      D-12

<PAGE>

Trust obtains an opinion of Mayer Brown & Platt or KPMG Peat Marwick (or another
comparable firm of attorneys or accountants) to the effect that, as a result of
such change, there no longer is "substantial authority" (within the meaning of
Section 6662(d)(2)(B)(i)) of the Code for such allocation; provided that the
                                                           -------------
Trust shall provide to Mr. Robert H. Smith and Mr. Robert P. Kogod (or in the
event of their death or disability, their executor, guardian or custodian, as
applicable), notice of such determination, together with a copy of such opinion,
and if, within forty five (45) days after the receipt thereof, the Trust is
provided an opinion of Hogan & Hartson LLP or Arthur Andersen LLP (or another
comparable firm of attorneys or accountants) to the effect that, notwithstanding
such change, there continues to be "substantial authority" (within the meaning
of Section 6662(d)(2)(B)(i) of the Code) for such allocations, the Trust shall
continue to make allocations of Nonrecourse Liabilities or Partner Nonrecourse
Debt to the SRW Partners as set forth in this Exhibit D.

          If a change in the Trust's allocations of Nonrecourse Liabilities or
Partner Nonrecourse Debt to the SRW Partners is required by reason of
circumstances described in the preceding sentence, the Trust and its
professional tax advisors shall cooperate in good faith with Messrs. Robert H.
Smith and Robert P. Kogod (or in the event of their death or disability, their
executor, guardian or custodian, as applicable) and their professional tax
advisors to develop alternative allocation arrangements and/or other mechanisms
that protect the federal income tax positions of the SRW Partners in the manner
contemplated by the allocations of Nonrecourse Liabilities or Partner
Nonrecourse Debt to the SRW Partners as set forth in this Exhibit D.

          8. Other Agreements With SRW Partners. Pursuant to the Merger
Agreement, the Trustee, the Trust, SRW, and SRW Partnership will enter into an
Assignment and Assumption Agreement, dated as of October 31, 2001, pursuant to
which the Trust will assume certain obligations of SRW Partnership made pursuant
to certain tax protection agreements (the "SRW Tax Protection Agreements"). A
list of those SRW Tax Protection Agreements is set forth on Schedule 5 to this
                                                            ----------
Exhibit D.
---------

          9.  Requirement for Delivery of Evidence of Filing of Form 8832.
Within 30 days following the SRW Merger, the Trustee shall provide to Messrs.
Smith and Kogod, as representatives of the SRW Partners, evidence, in the form
of a certified mail return receipt, that the Trust filed with the Internal
Revenue Service Form 8832 electing pursuant to Treasury Regulation (S)
301.7701-3(c)(1)(i) to be treated either as a domestic eligible entity with a
single owner electing to be disregarded as a separate entity or a partnership,
as applicable, not later than one day prior to the closing of the SRW Merger.

          10. Amendment of this Agreement. This Agreement may not be amended,
directly or indirectly (including by reason of a merger between the Trust and
another entity) except by a written instrument signed by the Trustee and
approved by the SRW Partners holding seventy-six percent (76%) of the then
outstanding Protected Units; provided, however, that any amendment that would
permit a sale of a Protected Property in violation of Section 2 or the
refinancing of debt in violation of Section 3, shall not be permitted without
the written approval of holders of seventy-six percent (76%) of the then
outstanding Protected Units held by SRW Partners that would be adversely
affected by such actions.

                                      D-13

          11. Modification of Section 5.8 of Annex A With Respect to Holders of
                                             -------
Protected Units. For purposes of applying Section 5.8.B. of Annex A to the
                                                            -------
Declaration of Trust with respect to all SRW Partners who hold Protected Units,
that Section shall be applied by substituting the phrase "provided that the
                                                          -------------
Trustee has acted in good faith and pursuant to its authority under this
Agreement" for the phrase "unless the Trustee has acted in bad faith and the act
or omission was material to the matter giving rise to the loss, liability or
benefit pursuant to its authority under the Agreement." For purposes of applying
Section 5.8.A. of Annex A to the Declaration of Trust with respect to all SRW
                  -------
Partners who hold Protected Units, that Section shall be applied by substituting
the following therefor:

          The Trustee shall not be liable for monetary damages to the Trust or
          any Unitholder for losses sustained or incurred as a result of errors
          in judgment or of any act or omission if the Trustee acted in good
          faith.

                                    EXHIBIT F
                   DESIGNATION OF THE PREFERENCES, CONVERSION
       AND OTHER RIGHTS, VOTING POWERS, RESTRICTIONS AND LIMITATIONS AS TO
                            SERIES A PREFERRED UNITS

     The Series A Preferred Units shall have the following designations,
preferences, rights, powers and duties:

     (1)  Certain Defined Terms. The following capitalized terms used in this
          ---------------------
Exhibit F shall have the respective meanings set forth below:
---------

          "Distribution Date" means (i) for any Distribution Period with respect
           -----------------
to which the Trust pays a distribution on the Class A Units, the date on which
such distribution is paid, or (ii) for any Distribution Period with respect to
which the Trust does not pay a distribution on the Class A Units, the date set
by the Trustee for payment of dividends on the Series A Preferred Shares.

          "Distribution Period" means quarterly periods commencing on January 1,
           -------------------
April 1, July 1 and October 1 of each year and ending on and including the day
preceding the first day of the next succeeding Distribution Period.

          "Fully Junior Units" shall mean the Common Units and any other class
           ------------------
or series of Units now or hereafter issued and outstanding over which the Series
A Preferred Units have a preference or priority in both (i) the payment of
distributions and (ii) the distribution of assets on any liquidation,
dissolution or winding up of the Trust.

          "Issue Date" shall mean the first date on which the Series A Preferred
           ----------
Units were issued.

          "Junior Units" shall mean the Common Units and any other class or
           ------------
series of Units now or hereafter issued and outstanding over which the Series A
Preferred Units have a preference or priority in the payment of distributions or
in the distribution of assets on any liquidation, dissolution or winding up of
the Trust.

          "Parity Units" has the meaning ascribed thereto in Section 7(B).
           ------------

          "set apart for payment" shall be deemed to include, without any action
           ---------------------
other than the following, the recording by the Trust in its accounting ledgers
of any accounting or bookkeeping entry which indicates, pursuant to a
declaration of distributions or other distribution by the Trustee, the
allocation of funds to be so paid on any series or class of Units of the Trust;
provided, however, that if any funds for any class or series of Junior Units or
any class or series of Units ranking on a parity with the Series A Preferred
Units as to the payment of distributions are placed in a separate account of the
Trust or delivered to a disbursing, paying or other similar agent, then "set
apart for payment" with respect to the Series A Preferred Units shall mean
placing such funds in a separate account or delivering such funds to a
disbursing, paying or other similar agent.

                                       F-1

<PAGE>

     (2)  Distributions.
          -------------

          (A) The Trustee, in its capacity as the holder of the then outstanding
Series A Preferred Units, shall be entitled to receive, when, as and if declared
by the Trustee out of funds legally available for such purpose, distributions
payable in cash in an amount per Series A Preferred Unit equal to the greater of
(a) $1.75 per annum or (b) the distributions (determined on each Distribution
Date) paid on the number of Class A-2 Units, or portion thereof, into which a
Series A Preferred Unit is convertible. The distributions referred to in clause
(b) of the preceding sentence shall equal the number of Class A-2 Units, or
portion thereof, into which a Series A Preferred Unit is convertible, multiplied
by the most recent quarterly distribution on a Class A-2 Unit on or before the
applicable Distribution Date. If the Trust pays an ordinary cash distribution on
the Class A-2 Units with respect to a Distribution Period after the date on
which the Distribution Date is declared pursuant to clause (ii) of the
definition of Distribution Date and the distribution calculated with respect to
clause (b) of the first sentence of this Section 2(A) is greater than the
distribution previously declared on the Series A Preferred Units with respect to
such Distribution Period, the Trust shall pay an additional distribution in
respect of the Series A Preferred Units on the date on which the distribution on
the Class A-2 Units is paid, in an amount equal to the difference between (y)
the distribution calculated pursuant to clause (b) of the first sentence of this
Section 2(A) and (z) the amount of distributions previously declared on the
Series A Preferred Units with respect to such Distribution Period. Distributions
shall begin to accrue and shall be fully cumulative from October 1, 2001,
whether or not in any Distribution Period or Periods there shall be funds of the
Trust legally available for the payment of such distributions, and shall be
payable quarterly, when, as and if declared by the Trustee, in arrears on each
Distribution Date commencing on the first Distribution Date after the Issue
Date. Accrued and unpaid distributions for any past Distribution Periods may be
declared and paid at any time and for such interim periods, without reference to
any regular Distribution Date, to the Trustee, in its capacity as the holder of
the Series A Preferred Units, on such date as may be fixed by the Trustee for
payment of the corresponding dividend on the Series A Preferred Shares.

          (B) The amount of distributions for each full Distribution Period
shall be equal to $0.4375. The amount of distribution for any Distribution
Period on the Series A Preferred Units that represents less than a full quarter
of a year shall be computed on the basis of a 360-day year of twelve 30-day
months. Holders of Series A Preferred Units shall not be entitled to any
distributions, whether payable in cash, property or securities, in excess of
cumulative distributions, as herein provided, on the Series A Preferred Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any distribution payment or payments on the Series A Preferred Units that may be
in arrears.

          (C) So long as any Series A Preferred Units are outstanding, no
distributions, except as described in the immediately following sentence, shall
be declared or paid or set apart for payment on any Parity Units for any period
unless full cumulative distributions have been or contemporaneously are declared
and paid or declared and a sum sufficient for the payment thereof set apart for
such payment on the Series A Preferred Units for all Distribution Periods
terminating on or prior to the distribution payment date for such class or
series of Parity Units. When distributions are not paid in full or a sum
sufficient for such payment is not set apart, as aforesaid, all distributions
declared upon Series A Preferred Units and all distributions declared

                                       F-2

<PAGE>

upon any other class or series of Parity Units shall be declared ratably in
proportion to the respective amounts of distributions accumulated and unpaid on
the Series A Preferred Units and accumulated and unpaid on such Parity Units.

     (D)  So long as any Series A Preferred Units are outstanding, no
distributions (other than distributions paid solely in Fully Junior Units or
options, warrants or rights to subscribe for or purchase Fully Junior Units)
shall be declared, or paid or set apart for payment or other distribution
declared or made upon Junior Units, nor shall any Junior Units be redeemed,
purchased or otherwise acquired (other than a redemption, purchase or other
acquisition of Common Units made for purposes of an employee incentive or
benefit plan of the Trustee, the Trust or any subsidiary) for any consideration
(or any moneys be paid to or made available for a sinking fund for the
redemption of any such Junior Units) by the Trust, directly or indirectly
(except by conversion into or exchange for Fully Junior Units), unless in each
case (i) the full cumulative distributions on all outstanding Series A Preferred
Units and any other Parity Units of the Trust shall have been paid or declared
and set apart for payment for all past Distribution Periods with respect to the
Series A Preferred Units and all past distribution periods with respect to such
Parity Units and (ii) sufficient funds shall have been paid or set apart for the
payment of the distribution for the current Distribution Period with respect to
the Series A Preferred Units and the current distribution period with respect to
such Parity Units.

     (3)  Liquidation Preference.
          ----------------------

          (A) In the event of any liquidation, dissolution or winding up of the
Trust, whether voluntary or involuntary, before any payment or distribution of
the assets (whether capital or surplus) of the Trust shall be made to or set
apart for the holders of Junior Units, the Trustee, in its capacity as holder of
the Series A Preferred Units, shall be entitled to receive Twenty Five Dollars
($25.00) per Series A Preferred Unit plus an amount equal to all distributions
(whether or not earned or declared) accrued and unpaid thereon to the date of
final distribution to the Trustee, in its capacity as such holder; but the
Trustee, in its capacity as the holder of Series A Preferred Units, shall not be
entitled to any further payment; provided that the distribution payable with
respect to the Distribution Period containing the date of final distribution
shall be equal to the greater of (i) the distribution provided in clause (a) of
the first sentence of Section 2(A) or (ii) the distribution determined pursuant
to clause (b) of the first sentence of Section 2(A) for the preceding
Distribution Period. If, upon any liquidation, dissolution or winding up of the
Trust, the assets of the Trust, or proceeds thereof, distributable to the
Trustee, in its capacity as the holder of Series A Preferred Units, shall be
insufficient to pay in full the preferential amount aforesaid and liquidating
payments on any other class or series of Parity Units, then such assets, or the
proceeds thereof, shall be distributed among the Trustee, in its capacity as the
holder of such Series A Preferred Units, and the holders of such other Parity
Units ratably in accordance with the respective amounts that would be payable on
such Series A Preferred Units and such other Parity Units if all amounts payable
thereon were paid in full. For the purposes of this Section 3, (x) a
consolidation or merger of the Trust with one or more partnerships, limited
liability companies, corporations, real estate investment trusts or other
entities, (y) a sale, lease or conveyance of all or substantially all of the
Trust's property or business or (z) a share exchange shall not be deemed to be a
liquidation, dissolution or winding up, voluntary or involuntary, of the Trust.

                                       F-3

<PAGE>

          (B) Subject to the rights of the holders of any series or class of
Units ranking on a parity with or prior to the Series A Preferred Units upon
liquidation, dissolution or winding up of the Trust, after payment shall have
been made in full to the Trustee, in its capacity as the holder of the Series A
Preferred Units, as provided in this Section 3, any other series or class or
classes of Junior Units shall, subject to any respective terms and provisions
(if any) applying thereto, be entitled to receive any and all assets remaining
to be paid or distributed, and the Trustee, in its capacity as the holder of the
Series A Preferred Units, shall not be entitled to share therein.

     (4)  Redemption Right.
          ----------------

          (A) Except as provided in Section 4(B), the Series A Preferred Units
shall not be redeemable prior to November 30, 2003. On and after such date, the
Trustee, at its option, may cause the Trust to redeem the Series A Preferred
Units, in whole at any time or from time to time in part at the option of the
Trustee, (x) for Class A-2 Units, subject to the conditions set forth in
paragraph (i) below, or (y) for cash in an amount per Series A Preferred Unit at
a redemption price of Twenty-Five Dollars ($25.00) per Series A Preferred Unit,
plus the amounts indicated in Section 4(A)(iii) below.

              (i)   The Series A Preferred Units shall be redeemed only if the
Trustee shall concurrently therewith redeem an equivalent number of shares of
Series A Preferred Shares for cash. Such redemption of Series A Preferred Units
shall occur substantially concurrently with the redemption by the Trustee of
such Series A Preferred Shares (such date of redemption the "Redemption Date").

              (ii)  In the event that the Trustee redeems Series A Preferred
Shares for cash (including payments of cash in lieu of fractional Shares), the
Trust shall redeem a like number of Series A Preferred Units in exchange for the
amount of cash that the Trustee is required to pay pursuant to the terms of the
Series A Preferred Shares in connection with such redemption.

              (iii) Upon any redemption of Series A Preferred Units pursuant to
this Section 4, the Trust shall pay any accrued and unpaid distributions in
arrears with respect to the Series A Preferred Units being redeemed for any
Distribution Period ending on or prior to the Redemption Date. If the Redemption
Date falls after a Trust Record Date and prior to the corresponding Distribution
Date, then the Trustee, in its capacity as the holder of the Series A Preferred
Units being redeemed, shall be entitled to distributions payable on the
corresponding Distribution Date notwithstanding the redemption of such Series A
Preferred Units before such Distribution Date. Except as provided above, the
Trust shall make no payment or allowance for unpaid distributions, whether or
not in arrears, on Series A Preferred Units called for redemption.

          (B) In the event that the Trustee is required to redeem any shares of
Series A Preferred Shares pursuant to the terms thereof, the Trust shall redeem
an equivalent number of Series A Preferred Units for consideration equal to the
consideration payable by the Trustee upon redemption of such shares of Series A
Preferred Shares.

                                       F-4

<PAGE>

     (5)  Conversion to Class A-2 Units.
          -----------------------------

          (A) In the event that a holder of Series A Preferred Shares exercises
its right to convert such Series A Preferred Shares into Shares, then,
concurrently therewith, an equivalent number of Series A Preferred Units shall
be automatically converted into a number of Class A-2 Units equal to (x) the
number of Shares issued upon conversion of such Series A Preferred Shares
divided by (y) the Conversion Factor. Any such conversion will be effective at
the same time as the conversion of Series A Preferred Shares into Shares is
effective.

          (B) The Trustee, as the holder of the Series A Preferred Units, at the
close of business on a dividend payment record date with respect to the Series A
Preferred Shares shall be entitled to receive the distribution payable on such
Series A Preferred Units on the corresponding Distribution Date notwithstanding
the conversion thereof following such dividend payment record date and prior to
such Distribution Date. However, Series A Preferred Units surrendered for
conversion during the period between the close of business on any dividend
payment record date with respect to the Series A Preferred Shares and the
opening of business on the corresponding Distribution Date (except Series A
Preferred Units converted upon conversion of Series A Preferred Shares after the
issuance of notice of redemption with respect to a redemption date for such
Series A Preferred Shares during such period, such Series A Preferred Units
being entitled to such distribution on the Distribution Date) must be
accompanied by payment of an amount equal to the distribution payable on such
Series A Preferred Units on such Distribution Date. A holder of Series A
Preferred Units on a dividend payment record date with respect to Series A
Preferred Shares who converts into Class A-2 Units on the corresponding
Distribution Date shall receive the distribution payable by the Trust on such
Series A Preferred Units on such date, and the Trustee, as the holder of the
Series A Preferred Units being converted, need not include payment of the amount
of such distribution upon surrender of Series A Preferred Units for conversion.
Except as provided above, the Trust shall make no payment or allowance for
unpaid distributions, whether or not in arrears, on converted Series A Preferred
Units or for distributions on the Class A-2 Units issued upon such conversion.

     (6)  Units to be Retired. All Series A Preferred Units which shall have
          -------------------
been issued and reacquired in any manner by the Trust shall be restored to the
status of authorized but unissued Units, without designation as to class or
series.

     (7)  Ranking.  Any class or series of Units shall be deemed to rank:
          -------

          (A) senior to the Series A Preferred Units, in the payment of
distributions and in the distribution of assets upon liquidation, dissolution or
winding up of the Trust, if the holders of such class or series of Units shall
be entitled to the receipt of distributions or of amounts distributable upon
liquidation, dissolution or winding up of the Trust, as the case may be, in
preference or priority to the holders of Series A Preferred Units;

          (B) on a parity with the Series A Preferred Units, in the payment of
distributions and in the distribution of assets upon liquidation, dissolution or
winding up of the Trust, whether or not the distribution rates, distribution
payment dates or redemption or liquidation prices per Unit thereof are different
from those of the Series A Preferred Units, if the holders of such class or
series of Units and the holders of the Series A Preferred Units are

                                       F-5

<PAGE>

entitled to the receipt of distributions and amounts distributable upon any
liquidation, dissolution or winding up of the Trust in proportion to their
respective amounts of distributions accrued and unpaid per Unit or liquidation
preferences, without preference or priority to each other ("Parity Units");

          (C) junior to the Series A Preferred Units, in the payment of
distributions or the distribution of assets upon any liquidation, dissolution or
winding up of the Trust, if such class or series of Units is Junior Units; and

          (D) junior to the Series A Preferred Units, in the payment of
distributions and in the distribution of assets upon any liquidation,
dissolution or winding up of the Trust, if such class or series of Units is
Fully Junior Units;

     (8)  Voting. Except as required by law, the Trustee, in its capacity as the
          ------
holder of the Series A Preferred Units, shall not be entitled to vote at any
meeting of the Unitholders or for any other purpose or otherwise to participate
in any action taken by the Trust or the Unitholders, or to receive notice of any
meeting of the Unitholders.

     (9)  Restriction on Ownership. The Series A Preferred Units shall be owned
          ------------------------
and held solely by the Trustee.

     (10) General. The rights of the Trustee, in its capacity as the holder of
          -------
the Series A Preferred Units, are in addition to and not in limitation on any
other rights or authority of the Trustee, in any other capacity, under the
Agreement. In addition, nothing contained in this Exhibit F shall be deemed to
                                                  ---------
limit or otherwise restrict any rights or authority of the Trustee under the
Agreement, other than in its capacity as the holder of the Series A Preferred
Units.

                   DESIGNATION OF THE PREFERENCES, CONVERSION
       AND OTHER RIGHTS, VOTING POWERS, RESTRICTIONS AND LIMITATIONS AS TO
                  SERIES B JUNIOR PARTICIPATING PREFERRED UNITS

     The Series B Junior Participating Preferred Units shall have the following
designations, preferences, rights, powers and duties:

     (1)  Certain Defined Terms. The following capitalized terms used in this
          ---------------------
Exhibit G shall have the respective meanings set forth below:

          "Distribution Date" means (i) for any Distribution Period with respect
           -----------------
to which the Trust pays a distribution on the Class A Units, the date on which
such distribution is paid, or (ii) for any Distribution Period with respect to
which the Trust does not pay a distribution on the Class A Units, the date set
by the Trustee for payment of dividends on the Series B Junior Participating
Preferred Shares.

          "Distribution Period" means quarterly periods commencing on January 1,
           -------------------
April 1, July 1 and October 1 of each year and ending on and including the day
preceding the first day of the next succeeding Distribution Period.

     (2)  Distributions.
          -------------

          (A) Subject to the prior and superior rights of the holders of Units
ranking prior and superior to the Series B Junior Participating Preferred Units
with respect to distributions, the Trustee, in its capacity as the holder of the
then outstanding Series B Junior Participating Preferred Units, shall be
entitled to receive, when, as and if declared by the Trustee out of funds
legally available for the purpose, quarterly cash distributions in an amount per
Series B Junior Participating Preferred Unit equal to the greater of (a) $1.00
or (b) subject to the provision for adjustment hereinafter set forth, 100 times
the aggregate per Unit amount of all cash distributions, and 100 times the
aggregate per Unit amount (payable in kind) of all non-cash distributions or
other distributions other than a distribution payable in Common Units or a
subdivision of the outstanding Common Units (by a reclassification or
otherwise), authorized on the Common Units since the immediately preceding
Distribution Date, or, with respect to the first Distribution Date, since the
first issuance of any Series B Junior Participating Preferred Unit or fraction
thereof. In the event the Trust shall at any time following August 31, 2001 (i)
declare any distribution on Common Units payable in Common Units, (ii) subdivide
the outstanding Common Units or (iii) combine the outstanding Common Units into
a smaller number of Units, then in each such case the amount to which holders of
Series B Junior Participating Preferred Units were entitled immediately prior to
such event under clause (b) of the preceding sentence shall be adjusted by
multiplying each such amount by a fraction the numerator of which is the number
of Common Units outstanding immediately after such event and the denominator of
which is the number of Common Units that were outstanding immediately prior to
such event.

          (B) The Trust shall declare a distribution on the Series B Junior
Participating Preferred Units as provided in paragraph (A) above at the time it
declares a distribution on the Common Units (other than a distribution payable
in Common Units).

                                       G-1

<PAGE>

          (C) No distribution (other than a distribution payable in Common
Units) shall be paid or payable to the holders of Common Units unless, prior
thereto, all accrued but unpaid distributions to the date of that distribution
shall have been paid to the holders of Series B Junior Participating Preferred
Units.

          (D) Distributions shall begin to accrue and be cumulative on
outstanding Series B Junior Participating Preferred Units from the Distribution
Date next preceding the date of issuance of such Series B Junior Participating
Preferred Units, unless the date of issuance of such Units is prior to the
record date for the first Distribution Date, in which case distributions on such
Units shall begin to accrue and be cumulative from the date of issuance of such
Units, or unless the date of issuance is a Distribution Date or is a date after
the record date for the determination of holders of Series B Junior
Participating Preferred Units entitled to receive a distribution and before such
Distribution Date, in either of which events such distributions shall begin to
accrue and be cumulative from such Distribution Date. Accrued but unpaid
distributions shall not bear interest. Distributions paid on the Series B Junior
Participating Preferred Units in an amount less than the total amount of such
distributions at the time accrued and payable on such Units shall be allocated
pro rata on a Unit-by-Unit basis among all such Units at the time outstanding.
The Trustee may fix a record date for the determination of the holders of Series
B Junior Participating Preferred Units entitled to receive payment of a
distribution declared thereon, which record date shall be no more than 30 days
prior to the date fixed for the payment thereof.

     (3)  Voting. Except as required by law, the Trustee, in its capacity as the
          ------
holder of the Series B Junior Participating Preferred Units, shall not be
entitled to vote at any meeting of the Unitholders or for any other purpose or
otherwise to participate in any action taken by the Trust or the Unitholders, or
to receive notice of any meeting of the Unitholders.

     (4)  Certain Restrictions.
          --------------------

          (A)  Whenever any quarterly distributions or other distributions
payable on the Series B Junior Participating Preferred Units as provided in
subsection 2 are in arrears, then, thereafter and until all accrued and unpaid
distributions, whether or not declared, on Series B Junior Participating
Preferred Units outstanding shall have been paid in full, the Trust shall not:

               (i)  declare or pay dividends on, make any other distributions
on, or redeem or purchase or otherwise acquire for consideration any Units
ranking junior (either as to dividends or upon liquidation, dissolution or
winding up) to the Series B Junior Participating Preferred Units, other than
distributions paid or payable in such junior Units;

               (ii) declare or pay dividends on or make any other distributions
on any Units ranking on a parity (either as to dividends or upon liquidation,
dissolution or winding up) with the Series B Junior Participating Preferred
Units, except dividends paid ratably on the Series B Junior Participating
Preferred Units and all such parity Units on which dividends are payable or in
arrears in proportion to the total amounts to which the holders of all such
Units are then entitled;

                                       G-2

<PAGE>

               (iii)  redeem or purchase or otherwise acquire for consideration
Units ranking on a parity (either as to dividends or upon liquidation,
dissolution or winding up) with the Series B Junior Participating Preferred
Units, provided that the Trust may at any time redeem, purchase or otherwise
acquire any such parity Units in exchange for Units of the Trust ranking junior
(either as to dividends or upon dissolution, liquidation or winding up) to the
Series B Junior Participating Preferred Units; or

               (iv)   purchase or otherwise acquire for consideration any Series
B Junior Participating Preferred Units, except in accordance with a purchase
offer made in writing or by publication (as determined by the Trustee) to all
holders of such Units upon such terms as the Trustee, after consideration of the
respective annual distribution rates and other relative rights and preferences
of the respective series and classes, shall determine in good faith will result
in fair and equitable treatment among the respective series or classes.

          (B)  The Trust shall not permit any subsidiary of the Trust to
purchase or otherwise acquire for consideration any Units of the Trust unless
the Trust could, under paragraph (A) of this Section, purchase or otherwise
acquire such Units at such time and in such manner.

     (5)  Reacquired Units. Any Series B Junior Participating Preferred Units
          ----------------
purchased or otherwise acquired by the Trust in any manner whatsoever shall
become authorized but unissued Units and may be reissued as Common Units or as
part of a new series of Preferred Units to be created by resolution or
resolutions of the Trustee, subject to the conditions and restrictions on
issuance set forth herein.

     (6)  Liquidation, Dissolution or Winding Up.
          --------------------------------------

          (A)  Upon any voluntary liquidation, dissolution or winding up of the
Trust, no distribution shall be made to the holders of Units ranking junior
(either as to dividends or upon liquidation, dissolution or winding up) to the
Series B Junior Participating Preferred Units unless, prior thereto, the
Trustee, in its capacity as holder of the Series B Junior Participating
Preferred Units, shall have received $1.00 per Unit, plus an amount equal to
accrued and unpaid distributions thereon, whether or not declared, to the date
of such payment (the "Series B Liquidation Preference"). Following the payment
of the full amount of the Series B Liquidation Preference, no additional
distributions shall be made to the holders of Series B Junior Participating
Preferred Units unless, prior thereto, the holders of Common Units shall have
received an amount per Unit (the "Common Adjustment") equal to the quotient
obtained by dividing (i) the Series B Liquidation Preference by (ii) 100 (as
appropriately adjusted as set forth in subparagraph C below to reflect such
events as unit splits, unit dividends and recapitalizations with respect to the
Common Units) (such number in clause (ii), the "Adjustment Number"). Following
the payment of the full amount of the Series B Liquidation Preference and the
Common Adjustment in respect of all outstanding Series B Junior Participating
Preferred Units and Common Units, respectively, holders of Series B Junior
Participating Preferred Units and holders of Common Units shall receive their
ratable and proportionate share of the remaining assets to be distributed in the
ratio, on a per Unit basis, of the Adjustment Number to 1 with respect to such
Series B Junior Participating Preferred Units and Common Units, on a per Unit
basis, respectively.

                                       G-3

          (B)  In the event, however, that there are not sufficient assets
available to permit payment in full of the Series B Liquidation Preference and
the liquidation preferences of all other series of Units, if any, which rank on
a parity with the Series B Junior Participating Preferred Units, then such
remaining assets shall be distributed ratably to the holders of the Series B
Junior Participating Preferred Units and such parity Units in proportion to
their respective liquidation preferences.

          (C)  In the event the Trust shall at any time following August 31,
2001 (i) declare any dividend on Common Units payable in Common Units, (ii)
subdivide the outstanding Common Units or (iii) combine the outstanding Common
Units into a smaller number of Units, then in each such case the Adjustment
Number in effect immediately prior to such event shall be adjusted by
multiplying such Adjustment Number by a fraction the numerator of which is the
number of Common Units outstanding immediately after such event and the
denominator of which is the number of Common Units that were outstanding
immediately prior to such event.

     (7)  Consolidation, Merger, etc. In case the Trust shall enter into any
          ---------------------------
consolidation, merger, combination or other transaction in which the Common
Units are exchanged for or changed into other Units or securities, cash and/or
any other property, then in any such case, the Series B Junior Participating
Preferred Units shall at the same time be similarly exchanged or changed in an
amount per Unit (subject to the provision for adjustment hereinafter set forth)
equal to 100 times the aggregate amount of Units, securities, cash and/or any
other property (payable in kind), as the case may be, into which or for which
each Common Unit is exchanged or changed. In the event the Trust shall at any
time (i) declare any dividend on Common Units payable in Common Units, (ii)
subdivide the outstanding Common Units or (iii) combine the outstanding Common
Units into a smaller number of Units, then in each such case the amount set
forth in the preceding sentence with respect to the exchange or change of Series
B Junior Participating Preferred Units shall be adjusted by multiplying such
amount by a fraction the numerator of which is the number of Common Units
outstanding immediately after such event and the denominator of which is the
number of Common Units that were outstanding immediately prior to such event.

     (8)  Redemption. The Series B Junior Participating Preferred Units shall
          ----------
not be redeemable by the Trust. The preceding sentence shall not limit the
ability of the Trust to purchase or otherwise deal in such Units to the extent
permitted by law.

     (9)  Ranking. The Series B Junior Participating Preferred Units shall rank
          -------
junior to all other series of the Trust's Preferred Units (whether with or
without par value) as to the payment of dividends and the distribution of
assets, unless the terms of any such series shall provide otherwise.

     (10) Restriction on Ownership. The Series B Junior Participating Preferred
          ------------------------
Units shall be owned and held solely by the Trustee.

     (11) General. The rights of the Trustee, in its capacity as the holder of
          -------
the Series B Junior Participating Preferred Units, are in addition to and not in
limitation on any other rights or authority of the Trustee in any other capacity
under the Agreement. In addition, nothing contained in this Exhibit G shall be
deemed to limit or otherwise restrict any rights or authority

                                       G-4

<PAGE>

of the Trustee under the Agreement, other than in its capacity as the holder of
the Series B Junior Participating Preferred Units.

     (12) Fractional Unit. Series B Junior Participating Preferred Units may be
          ---------------
issued in fractions of a Unit that are integral multiples of one-one hundredth
of a Unit, which shall entitle the holder, in proportion to such holder's
fractional Units, to exercise voting rights, receive dividends and participate
in distributions and to have the benefit of all other rights of holders of
Series B Junior Participating Preferred Units.

          "Distribution Period" means quarterly periods commencing on January 1,
           -------------------
April 1, July 1 and October 1 of each year and ending on and including the day
preceding the first day of the next succeeding Distribution Period.

           ------------------
or series of Units now or hereafter issued and outstanding as to which the
Series C Preferred Units have a preference or priority in both (i) the payment
of distributions and (ii) the distribution of assets on any liquidation,

provided, however, that if any funds for any class or series of Junior Units or
any class or series of Units ranking on a parity with the Series C Preferred
Units as to the payment of distributions are placed in a separate account of the
Trust or delivered to a disbursing, paying or other similar agent, then "set

     (2)  Distributions.
          -------------

          (A) The Trustee, in its capacity as the holder of the then outstanding
Series C Preferred Units, shall be entitled to receive for such purpose, when,
as and if authorized or declared by the Trustee, out of funds legally available
for such purpose, cash distributions in an amount per Series C Preferred Unit
equal to 8.625% of the Series C Liquidation Preference (as defined below) per
annum (equivalent to $2.15625 per share). Distributions shall begin to accrue
and shall be fully cumulative from October 1, 2001, whether or not in any
Distribution Period or Periods there shall be funds of the Trust legally
available for the payment of such distributions, and shall be payable quarterly,
when, as and if declared by the Trustee, in arrears on each Distribution Date
commencing with the first Distribution Date following the Issue Date. Accrued
and unpaid distributions for any past Distribution Periods may be declared and
paid at any time and for such interim periods, without reference to any regular
Distribution Date, to the Trustee, in its capacity as the holder of the Series C
Preferred Units, on such date as may be fixed by the Trustee for payment of the
corresponding dividend on the Series C Preferred Shares.

          (B) The amount of distributions for each full Distribution Period
shall be equal to $0.5390625. The amount of distributions for any Distribution
Period on the Series C Preferred Units that represents less than a full quarter
of a year shall be computed on the basis of a 360-day year of twelve 30-day
months. Holders of Series C Preferred Units shall not be entitled to any
distributions, whether payable in cash, property or securities, in excess of
cumulative distributions, as provided herein, on the Series C Preferred Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any distribution payment or payments on the Series C Preferred Units that may be
in arrears.

          (C) So long as any Series C Preferred Units are outstanding, no
distributions, except as described in the immediately following sentence, shall
be declared or paid or set apart for payment on any Parity Units for any period
unless (i) full cumulative distributions have been or contemporaneously are paid
or declared and a sum sufficient for the payment thereof set apart for payment
for all past Distribution Periods with respect to the Series C Preferred Units
and (ii) a sum sufficient for the payment thereof has been or contemporaneously
is set apart for payment of the distribution for the current Distribution Period
with respect to the Series C Preferred Units. When distributions are not paid in
full, or a sum sufficient for such payment is not set apart for payment on the
Series C Preferred Units and any Parity Units as provided above, all
distributions declared on the Series C Preferred Units and any Parity Units
shall be declared ratably in proportion to the respective amounts of
distributions accrued and unpaid on the Series C Preferred Units and on such
Parity Units.

          (D) So long as any Series C Preferred Units are outstanding, no
distributions (other than distributions paid solely in Fully Junior Units or
options, warrants or rights to subscribe for or purchase Fully Junior Units)
shall be declared or paid or set apart for payment or other distribution, shall
be declared or made on Junior Units, nor shall any Junior Units be redeemed,
purchased or otherwise acquired (other than a redemption, purchase or other
acquisition of Common Units made for purposes of an employee incentive or
benefit plan of the Trustee, the Trust or any subsidiary) for any consideration
(or any moneys be paid to or made available for a sinking fund for the
redemption of any Junior Units) by the Trust, directly or indirectly (except by
conversion into or exchange for Fully Junior Units), unless in each case (i)

                                       H-2

<PAGE>

full cumulative distributions have been or contemporaneously are paid or
declared and a sum sufficient for the payment thereof set apart for payment for
all past Distribution Periods with respect to the Series C Preferred Units and
all past distribution periods with respect to any Parity Units and (ii) a sum
sufficient for the payment thereof has been or contemporaneously is set apart
for the payment of the distribution for the current Distribution Period with
respect to the Series C Preferred Units and the current distribution period with
respect to any Parity Units.

          (E) No distributions on the Series C Preferred Units shall be paid or
set apart for payment by the Trust at such time as the terms and provisions of
any agreement of the Trustee or the Trust, including any agreement relating to
indebtedness of either of them, 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.

     (3)  Liquidation Preference.
          ----------------------

          (A) In the event of any liquidation, dissolution or winding up of the
Trust, whether voluntary or involuntary, before any payment or distribution of
the assets of the Trust (whether capital or surplus) is made to or set apart for
the holders of the Common Units or any other class or series of Units of the
Trust now or hereafter issued and outstanding to which the Series C Preferred
Units have preference or priority in the distribution of assets on any
liquidation, dissolution or winding up of the Trust, the Trustee, in its
capacity as holder of the Series C Preferred Units, shall be entitled to receive
out of the assets of the Trust legally available for such purpose, liquidating
distributions in the amount of Twenty Five Dollars ($25.00) (the "Series C
Liquidation Preference") per Series C Preferred Unit, plus an amount equal to
all distributions (whether or not earned or authorized or declared) accrued and
unpaid thereon to the date of final distribution to the Trustee, in its capacity
as such holder; but the Trustee, in its capacity as the holder of Series C
Preferred Units shall not be entitled to any further payment. If, upon any such
liquidation, dissolution or winding up of the Trust, the assets of the Trust, or
proceeds thereof, distributable to the Trustee, in its capacity as the holder of
Series C Preferred Units, are insufficient to pay in full such preferential
amount and the corresponding amounts with respect to all Parity Units, then such
assets, or the proceeds thereof, shall be distributed among the Trustee, in its
capacity as the holder of such Series C Preferred Units, and the holders of such
other Parity Units in proportion to the full liquidation distributions to which
they would otherwise be respectively entitled.

          (B) Subject to the rights of the holders of Units of any class or
series of Units ranking on a parity with or senior to the Series C Preferred
Units in the distribution of assets on any liquidation, dissolution or winding
up of the Trust, whether voluntary or involuntary, after payment has been made
in full to the Trustee, in its capacity as the holder of the Series C Preferred
Units, as provided in this Section 3, the holders any Junior Units shall,
subject to any respective terms and provisions (if any) applying thereto, be
entitled to receive any and all assets remaining to be paid or distributed, and
the Trustee, in its capacity as the holder of the Series C Preferred Units,
shall not be entitled to share therein.

          (C) For the purposes of this Section 3, (x) a consolidation or merger
of the Trust with or into one or more partnerships, limited liability companies,
corporations, real estate

                                       H-3

<PAGE>

investment trusts or other entities, (y) a sale, lease or conveyance of all or
substantially all of the Trust's property or business or (z) a share exchange
shall not be deemed to be a liquidation, dissolution or winding up of the Trust,
whether voluntary or involuntary.

     (4)  Redemption Right.
          ----------------

          (A)  Except as provided in Section 4(B), the Series C Preferred Units
shall not be redeemable prior to August 20, 2002. On and after such date, the
Trustee may cause the Trust, at its option, to redeem the Series C Preferred
Units, in whole at any time, or in part from time to time, for cash at a
redemption price of $25.00 per Series C Preferred Unit, plus the amounts
indicated in Section 4(A)(iii) below.

               (i)   The Series C Preferred Units shall be redeemed only if the
Trustee shall concurrently therewith redeem an equivalent number of shares of
Series C Preferred Shares for cash. Such redemption of Series C Preferred Units
shall occur substantially concurrently with the redemption by the Trustee of
such Series C Preferred Shares (such date of redemption the "Redemption Date").

               (ii)  In the event that the Trustee redeems Series C Preferred
Shares for cash (including payments of cash in lieu of fractional Shares), the
Trust shall redeem a like number of Series C Preferred Units in exchange for the
amount of cash that the Trustee is required to pay pursuant to the terms of the
Series C Preferred Shares in connection with such redemption.

               (iii) Upon any redemption of Series C Preferred Units pursuant to
this Section 4, the Trust shall pay all distributions accrued and unpaid, if
any, in arrears with respect to the Series C Preferred Units being redeemed for
any Distribution Period ending on or prior to the Redemption Date. If the
Redemption Date falls after a Trust Record Date and prior to the corresponding
Distribution Date, then the Trustee, in its capacity as the holder of the Series
C Preferred Units being redeemed, shall be entitled to distributions payable on
the corresponding Distribution Date notwithstanding the redemption of such
Series C Preferred Units before such Distribution Date. Except as provided
above, the Trust shall make no payment or allowance for unpaid distributions,
whether or not in arrears, on Series C Preferred Units called for redemption.

          (B)  In the event that the Trustee is required to redeem any shares of
Series C Preferred Shares pursuant to the terms thereof, the Trust shall redeem
an equivalent number of Series C Preferred Units for consideration equal to the
consideration payable by the Trustee upon redemption of such shares of Series C
Preferred Shares.

     (5)  Shares to be Retired. All Series C Preferred Units which are issued
          --------------------
and reacquired in any manner by the Trust shall be restored to the status of
authorized but unissued Units of the Trust, without designation as to class or
series.

<PAGE>

     (6)  Ranking. Any class or series of Units shall be deemed to rank:
          -------

          (A) senior to the Series C Preferred Units, in the payment of
distributions and in the distribution of assets upon liquidation, dissolution or
winding up of the Trust, if the holders of such class or series of Units shall
be entitled to the receipt of distributions or of amounts distributable upon
liquidation, dissolution or winding up of the Trust, as the case may be, in
preference or priority to the holders of Series C Preferred Units;

          (B) on a parity with the Series C Preferred Units in the payment of
distributions and as to the distribution of assets upon liquidation, dissolution
or winding up of the Trust, whether or not the distribution rates, distribution
payment dates or redemption or liquidation prices per Unit thereof are different
from those of the Series C Preferred Units, if the holders of such class or
series of Units and the Series C Preferred Units are entitled to the receipt of
distributions and amounts distributable upon any liquidation, dissolution or
winding up of the Trust in proportion to their respective amounts of
distributions accrued and unpaid per Unit or liquidation preferences, without
preference or priority to each other ("Parity Units");

          (C) junior to the Series C Preferred Units, in the payment of
distributions or in the distribution of assets upon any liquidation, dissolution
or winding up of the Trust, if such class or series of Units is Junior Units;
and

          (D) junior to the Series C Preferred Units, in the payment of
distributions and in the distribution of assets upon any liquidation,
dissolution or winding up of the Trust, if such class or series of Units is
Fully Junior Units;

     (7)  Voting. Except as required by law, the Trustee, in its capacity as the
          ------
holder of the Series C Preferred Units, shall not be entitled to vote at any
meeting of the Unitholders or for any other purpose or otherwise to participate
in any action taken by the Trust or the Unitholders, or to receive notice of any
meeting of the Unitholders.

     (8)  Restriction on Ownership. The Series C Preferred Units shall be owned
          ------------------------
and held solely by the Trustee.

     (9)  General. The rights of the Trustee, in its capacity as the holder of
          -------
the Series C Preferred Units, are in addition to and not in limitation on any
other rights or authority of the Trustee, in any other capacity, under the
Agreement. In addition, nothing contained in this Exhibit H shall be deemed to
limit or otherwise restrict any rights or authority of the Trustee under the
Agreement, other than in its capacity as the holder of the Series C Preferred
Units.

          (2)  Distributions.
               -------------

               (A) The Trustee, in its capacity as the holder of the then
outstanding Series D Preferred Units, shall be entitled to receive, when, as and
if declared by the Trustee, out of funds legally available for that purpose,
distributions payable in cash in an amount per Series D Preferred Unit equal to

               (C) So long as any Series D Preferred Units are outstanding, no
full distributions, except as described in the immediately following sentence,
shall be declared or paid or set apart for payment on any Parity Units for any
period unless full cumulative distributions have been or contemporaneously are
declared and paid or declared and a sum sufficient for the payment thereof set
apart for such payment on the Series D Preferred Units for all past Distribution
Periods terminating on or prior to the distribution payment date for such class
or series of Parity Units. When distributions are not paid in full (or a sum
sufficient for such full payment is not so set apart), as aforesaid, all
distributions declared upon Series D Preferred Units and all distributions
declared upon any other class or series of Parity Units shall be declared
ratably in proportion to the respective amounts of distributions accumulated and
unpaid on the Series D Preferred Units and accumulated and unpaid on such Parity
Units.

               (D) So long as any Series D Preferred Units are outstanding, no
distributions (other than distributions paid solely in Fully Junior Units or
options, warrants or rights to subscribe for or purchase Fully Junior Units)
shall be declared or paid or set apart for payment or other distribution, shall
be declared or made or set apart for payment upon Junior Units, nor shall any
Junior Units be redeemed, purchased or otherwise acquired (other than a
redemption, purchase or other acquisition of Common Units made for purposes of

subsidiary) for any consideration (or any moneys be paid to or made available
for a sinking fund for the redemption of any such Junior Units) by the Trust,
directly or indirectly (except by conversion into or exchange for Fully Junior
Units), unless in each case (i) the full cumulative distributions on all
outstanding Series D Preferred

Series D Preferred Units and all past distribution periods with respect to such
Parity Units and (ii) sufficient funds shall have been paid or declared and set
apart for the payment of the distribution for the current Distribution Period

Preferred Units shall first be credited against the earliest accrued but unpaid
distribution due which remains payable.

by the Trustee or paid or set apart for payment by the Trust at such time as the
terms and provisions of any agreement of the Trustee or the Trust, including any
agreement relating to indebtedness of either of them, prohibits such

thereof or a default thereunder, or if such declaration or payment shall be
restricted or prohibited by law.

     (3)  Liquidation Preference.
          ----------------------

          (A) In the event of any liquidation, dissolution or winding up of the
Trust, whether voluntary or involuntary, before any payment or distribution of
the assets of the Trust (whether capital or surplus) shall be made to or set
apart for the holders of Junior Units, the Trustee, in its capacity as holder of
the Series D Preferred Units, shall be entitled to receive Twenty Five Dollars
($25.00) per Series D Preferred Unit plus an amount equal to all distributions
(whether or not earned or declared) accrued and unpaid thereon to the date of
final distribution to the Trustee, in its capacity as such holder; but the
Trustee, in its capacity as the holder of Series D Preferred Units shall not be
entitled to any further payment. If, upon any such liquidation, dissolution or
winding up of the Trust, the assets of the Trust, or proceeds thereof,
distributable to the Trustee, in its capacity as the holder of Series D
Preferred Units, shall be insufficient to pay in full the preferential amount

then such assets, or the proceeds thereof, shall be distributed among the
Trustee, in its capacity as the holder of such Series D Preferred Units, and the
holders of such other Parity Units ratably in accordance with the respective
amounts that would be payable on such Series D Preferred Units and such other
Parity Units if all amounts payable thereon were paid in full. For the purposes
of this Section 3, (x) a consolidation or merger of the Trust with one or more
partnerships, limited liability companies, corporations, real estate investment
trusts or other entities, (y) a sale, lease or conveyance of all or
substantially all of the Trust's property or business or (z) a share exchange

involuntary, of the Trust.

          (B) Subject to the rights of the holders of Units of any series or
class or classes ranking on a parity with or senior to the Series D Preferred
Units upon liquidation, dissolution or winding up, upon any liquidation,
dissolution or winding up of the Trust, after payment shall have been made in
full to the Trustee, in its capacity as the holder of the Series D Preferred
Units, as provided in this Section 3, any other series or class or classes of
Junior Units shall, subject to the respective terms and provisions (if any)
applying thereto, be entitled to receive any and all assets remaining to be paid
or distributed, and the Trustee, in its capacity as the holder of the Series D
Preferred Units, shall not be entitled to share therein.

     (4)  Redemption Right.
          ----------------

          (A)  The Series D Preferred Units shall not be redeemable prior to
August 6, 2004. On and after such date, the Trustee may cause the Trust, at its
option, to redeem the Series D Preferred Units, in whole at any time or from
time to time in part, at the option of the Trust at a redemption price of
Twenty-Five Dollars ($25.00) per Series D Preferred Unit, plus the amounts
indicated in Section 4(A)(iii) below.

               (i)   The Series D Preferred Units shall be redeemed only if the

such Series D Preferred Shares (such date of redemption the "Redemption Date").

               (ii)  In the event that the Trustee redeems shares of Series D
Preferred Shares for cash (including payments of cash in lieu of fractional

the terms of the Series D Preferred Shares in connection with such redemption.

               (iii) Upon any redemption of Series D Preferred Units pursuant to
this Section 4, the Trust shall pay any accrued and unpaid distributions in
arrears with respect to the Series D Preferred Units being redeemed for any
Distribution Period ending on or prior to the Redemption Date. If the Redemption
Date falls after a Trust Record Date and prior to the corresponding Distribution
Date, then the Trustee, in its capacity as the holder of the Series D Preferred
Units being redeemed, shall be entitled to the distribution payable on such on
the corresponding Distribution Date notwithstanding the redemption of such
Series D Preferred Units before such Distribution Date. Except as provided
above, the Trust shall make no payment or allowance for unpaid distributions,
whether or not in arrears, on Series D Preferred Units called for redemption.

          (B)  In the event that the Trustee is required to redeem any shares of
Series D Preferred Shares pursuant to the terms thereof, the Trust shall redeem
an equivalent number of Series D Preferred Units for consideration equal to the
consideration payable by the Trustee upon redemption of such shares of Series D
Preferred Shares.

     (5)  Shares to be Retired. All Series D Preferred Units which shall have
          --------------------
been issued and reacquired in any manner by the Trust shall be restored to the

distributions and in distribution of assets upon liquidation, dissolution or
winding up of the Trust, whether or not the distribution rates, distribution
payment dates or redemption or liquidation prices per Unit are different from
those of the Series D Preferred Units, if the holders of such class or series of
Units and the holders of the Series D Preferred Units are entitled to the
receipt of distributions and amounts distributable upon any liquidation,
dissolution or winding up of the Trust in proportion to their respective amounts
of distributions accrued and unpaid per Unit or liquidation preferences, without
preference or priority to each other ("Parity Units");

          (C) junior to the Series D Preferred Units, in the payment of
distributions or in the distribution of assets upon any liquidation, dissolution
or winding up of the Trust, if such class or series of Units is Junior Units;

                   DESIGNATION OF THE PREFERENCES, CONVERSION
       AND OTHER RIGHTS, VOTING POWERS, RESTRICTIONS AND LIMITATIONS AS TO
                            SERIES E PREFERRED UNITS

           ------------------
or series of Units now or hereafter issued and outstanding over which the Series
E Preferred Units have a preference or priority in both (i) the payment of
dividends and (ii) the distribution of assets on any liquidation, dissolution or

           ----------
Units are issued.

          "Junior Units" shall mean the Common Units and any other class or

<PAGE>

     (2)  Distributions.
          -------------

          (A)  The Trustee, in its capacity as the holder of the then
outstanding Series E Preferred Units, shall be entitled to receive when, as and
if authorized or declared by the Trustee out of funds legally available for such
purpose, cash distributions in an amount per Series E Preferred Unit equal to
8.375% of the Series E Liquidation Preference (as defined below) per annum
(equivalent to $2.09375 per share). Distributions shall begin to accrue and
shall be fully cumulative from and including the Issue Date, whether or not in
any Distribution Period or Periods there are funds of the Trust legally
available for the payment of such distributions, and shall be payable quarterly,
when, as and if declared by the Trustee, in arrears on each Distribution Date.
Accrued and unpaid distributions for any past Distribution Periods may be
authorized or declared and paid at any time and for such interim periods,
without reference to any regular Distribution Date, to the Trustee, in its
capacity as the holder of the Series E Preferred Units, on such date as may be
fixed by the Trustee for payment of the corresponding dividend on the Series E
Preferred Shares.

          (B)  The amount of distributions for each full Distribution Period
shall be equal to $0.5234375. The amount of distribution for any Distribution
Period on the Series E Preferred Units that represents less than a full quarter
of a year shall be computed on the basis of a 360-day year of twelve 30-day
months. Holders of Series E Preferred Units shall not be entitled to any
distributions, whether payable in cash, property or securities, in excess of
cumulative distributions, as herein provided, on the Series E Preferred Units.
No interest, or sum of money in lieu of interest, shall be payable in respect of
any distribution payment or payments on the Series E Preferred Units that may be
in arrears.

          (C)  So long as any Series E Preferred Units are outstanding, no
distributions, except as described in the immediately following sentence, shall
be declared or paid or set apart for payment on any Parity Units for any period
unless (i) full cumulative distributions have been or contemporaneously are paid
or declared and a sum sufficient for the payment thereof set apart for payment
for all past Distribution Periods with respect to the Series E Preferred Units
and (ii) a sum sufficient for the payment thereof has been or contemporaneously
is set apart for payment of the distribution for the current Distribution Period
with respect to the Series E Preferred Units. When distributions are not paid in
full, or a sum sufficient for the payment thereof is not set apart for payment,
on the Series E Preferred Units and any Parity Units as provided above, all
distributions declared on the Series E Preferred Units and all distributions
declared upon any other class or series of Parity Units shall be declared
ratably in proportion to the respective amounts of distributions accrued and
unpaid on the Series E Preferred Units and accrued and unpaid on such Parity
Units.

          (D)  So long as any Series E Preferred Units are outstanding, no
distributions (other than distributions paid solely in Fully Junior Units or
options, warrants or rights to subscribe for or purchase Fully Junior Units)
shall be declared or paid or set apart for payment or other distribution shall
be declared or made on Junior Units, nor shall any Junior Units be redeemed,
purchased or otherwise acquired (other than a redemption, purchase or other
acquisition of Common Units made for purposes of an employee incentive or
benefit plan of the Trustee, the Trust or any subsidiary) for any consideration
(or any moneys be paid to or made available for a sinking fund for the
redemption of any Junior Units) by the Trust, directly or

                                       J-2

<PAGE>

indirectly (except by conversion into or exchange for Fully Junior Units),
unless in each case (i) full cumulative distributions have been or
contemporaneously are paid or declared and a sum sufficient for the payment
thereof set apart for payment for all past Distribution Periods with respect to
the Series E Preferred Units and (ii) a sum sufficient for the payment thereof
has been or contemporaneously is set apart for payment of the distribution for
the current Distribution Period with respect to any Parity Units. Any
distribution payment on the Series E Preferred Units shall first be credited
against the earliest accrued but unpaid distribution due which remains payable.

          (E)   No distributions on the Series E Preferred Units shall be
declared by the Trustee or paid or set apart for payment by the Trust at such
time as the terms and provisions of any agreement of the Trustee or the Trust,
including any agreement relating to indebtedness of either of them, 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, payment or setting
apart for payment is restricted or prohibited by law.

     (3)  Liquidation Preference.
          ----------------------

          (A)   Upon any liquidation, dissolution or winding up of the Trust,
whether voluntary or involuntary, before any payment or distribution of the
assets of the Trust (whether capital or surplus) is made to or set apart for the
holders of Common Units or any other class or series of Units of the Trust now
or hereafter issued and outstanding to which the Series E Preferred Units have
preference or priority in the distribution of assets on any liquidation,
dissolution or winding up of the Trust, the Trustee, in its capacity as holder
of the Series E Preferred Units, shall be entitled to receive out of the assets
of the Trust legally available for such purpose, liquidating distributions in
the amount of Twenty Five Dollars ($25.00) (the "Series E Liquidation
Preference") per Series E Preferred Unit plus an amount equal to all
distributions (whether or not earned or authorized or declared) accrued and
unpaid thereon to the date of final distribution to the Trustee, in its capacity
as such holder; but the Trustee, in its capacity as the holder of Series E
Preferred Units shall not be entitled to any further payment. If, upon any
liquidation, dissolution or winding up of the Trust, the assets of the Trust, or
proceeds thereof, distributable to the Trustee, in its capacity as the holder of
Series E Preferred Units, are insufficient to pay in full such preferential
amount with respect to the Series E Preferred Units and the corresponding amount
with respect to all Parity Units, then such assets, or the proceeds thereof,
shall be distributed among the Trustee, in its capacity as the holder of such
Series E Preferred Units, and the holders of such Parity Units in proportion to
the full liquidating distributions to which they would otherwise be respectively
entitled.

          (B)   Subject to the rights of the holders of Units of any series or
class ranking on a parity with or senior to the Series E Preferred Units in the
distribution of assets on any liquidation, dissolution or winding up of the
Trust, upon any liquidation, dissolution or winding up of the Trust, whether
voluntary or involuntary, after payment has been made in full to the Trustee, in
its capacity as the holder of the Series E Preferred Units, as provided in this
Section 3, the holders of any Junior Units shall, subject to any respective
terms and provisions applying thereto, be entitled to receive any and all assets
remaining to be paid or distributed, and the

                                       J-3

<PAGE>

Trustee, in its capacity as the holder of the Series E Preferred Units, shall
not be entitled to share therein.

          (C)  For the purposes of this Section 3, (x) a consolidation or merger
of the Trust with or into one or more partnerships, limited liability companies,
corporations, real estate investment trusts or other entities, (y) a sale, lease
or conveyance of all or substantially all of the Trust's property or business or
(z) a share exchange shall not be deemed to be a liquidation, dissolution or
winding up of the Trust, whether voluntary or involuntary.

     (4)  Redemption Right.
          ----------------

          (A)  Except as provided in Section 4(B), the Series E Preferred Units
are not redeemable by the Trust prior to August 13, 2004. On and after such
date, the Trustee may cause the Trust, at its option, to redeem the Series E
Preferred Units, in whole at any time or in part from time to time, for cash at
a redemption price and $25.00 per Series E Preferred Unit, plus the amounts
indicated in Section 4(A)(iii) below.

               (i)   The Series E Preferred Units shall be redeemed only if the
Trustee shall concurrently therewith redeem an equivalent number of shares of
Series E Preferred Shares for cash. Such redemption of Series E Preferred Units
shall occur substantially concurrently with the redemption by the Trustee of
such Series E Preferred Shares (such date of redemption the "Redemption Date").

               (ii)  In the event that the Trustee redeems shares of Series E
Preferred Shares for cash (including payments of cash in lieu of fractional
Shares), the Trust shall redeem a like number of Series E Preferred Units in
exchange for the amount of cash that the Trustee is required to pay pursuant to
the terms of the Series E Preferred Shares in connection with such redemption.

               (iii) Upon any redemption of Series E Preferred Units pursuant to
this Section 4, the Trust shall pay all distributions accrued and unpaid
thereon, if any, in arrears for any Distribution Period ending on or prior to
the Redemption Date. If the Redemption Date falls after a Trust Record Date and
prior to the corresponding Distribution Date, then the Trustee, in its capacity
as the holder of the Series E Preferred Units being redeemed, shall be entitled
to distributions payable on the corresponding Distribution Date notwithstanding
the redemption of such Series E Preferred Units before such Distribution Date.
Except as provided above, the Trust shall make no payment or allowance for
unpaid distributions, whether or not in arrears, on Series E Preferred Units
called for redemption.

          (B)  In the event that the Trustee is required to redeem any shares of
Series E Preferred Shares pursuant to the terms thereof, the Trust shall redeem
an equivalent number of Series E Preferred Units for consideration equal to the
consideration payable by the Trustee upon redemption of such shares of Series E
Preferred Shares.

     (5)  Shares to be Retired. All Series E Preferred Units which are issued
          --------------------

           -------------------------------
partner of Archstone Communities Limited Partnership, a Delaware limited
partnership ("ACLP") of its Exchange Right to exchange such partner's Series E
Preferred Limited Partnership Interests in ACLP for Series E Preferred Units,
the Series E Preferred Units so issued upon exchange shall automatically, and

partner, be converted into Series E Preferred Shares and the Trustee shall
thereafter own all of the Series E Preferred Units so issued.

or winding up of the Trust, if the holders of such class or series are entitled
to the receipt of distributions or amounts distributable on any liquidation,
dissolution or winding up of the Trust, as the case may be, in preference or
priority to the holders of Series E Preferred Units;

           (B)  on a parity with the Series E Preferred Units in the payment of
distributions or in the distribution of assets upon liquidation, dissolution or
winding up of the Trust, whether or not the distribution rates, distribution
payment dates or redemption or liquidation prices per Unit be different from
those of the Series E Preferred Units, if the holders of such class or series of
Units and the Series E Preferred Units are entitled to the receipt of
distributions and amounts distributable on any liquidation, dissolution or
winding up of the Trust in proportion to their respective amounts of
distributions accrued and unpaid per Unit or liquidation preferences, without

           -------
the Series E Preferred Units, are in addition to and not in limitation on any
other rights or authority of the Trustee, in any other capacity, under the
Agreement. In addition, nothing contained in this Exhibit J shall be deemed to

          (C) So long as any Series F Preferred Units are outstanding, no
distributions, except as described in the immediately following sentence, shall
be declared or paid or set apart for payment on any Parity Units for any period
unless (i) full cumulative distributions have been or contemporaneously are paid
or declared and a sum sufficient for the payment thereof set apart for payment
for all past Distribution Periods with respect to the Series F Preferred Units
and (ii) a sum sufficient for the payment thereof has been or contemporaneously
is set apart for payment of the distribution for the current Distribution Period
with respect to the Series F Preferred Units. When distributions are not paid in
full, or a sum sufficient for the payment thereof is not set apart for payment,
on the Series F Preferred Units and any Parity Units as provided above, all
distributions declared on the Series F Preferred Units and all distributions
declared upon any other class or series of Parity Units shall be declared
ratably in proportion to the respective amounts of distributions accrued and
unpaid on the Series F Preferred Units and accrued and unpaid on such Parity
Units.

          (D) So long as any Series F Preferred Units are outstanding, no
distributions (other than distributions paid solely in Fully Junior Units or
options, warrants or rights to subscribe for or purchase Fully Junior Units)
shall be declared or paid or set apart for payment or other distribution, shall
be declared or made on Junior Units, nor shall any Junior Units be redeemed,
purchased or otherwise acquired (other than a redemption, purchase or other
acquisition of Common Units made for purposes of an employee incentive or
benefit plan of the Trustee, the Trust or any subsidiary) for any consideration
(or any moneys be paid to or made available for a sinking fund for the
redemption of any Junior Units) by the Trust, directly or indirectly (except by
conversion into or exchange for Fully Junior Units), unless in each case (i)

                                       K-2

full cumulative distributions have been or contemporaneously are paid or
declared and a sum sufficient for the payment thereof set apart for payment for
all past Distribution Periods with respect to the Series F Preferred Units and
(ii) has been or contemporaneously is set apart for the payment of the
distribution for the current Distribution Period with respect to any Parity
Units.

          (E) No distributions on the Series F Preferred Units shall be declared
by the Trustee or paid or set apart for payment by the Trust at such time as the
terms and provisions of any agreement of the Trustee or the Trust, including any
agreement relating to indebtedness of either of them, 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, payment or setting
apart for payment is restricted or prohibited by law.

     (3)  Liquidation Preference.
          ----------------------

          (A) Upon any liquidation, dissolution or winding up of the Trust,
whether voluntary or involuntary, before any payment or distribution of the
assets of the Trust (whether capital or surplus) is made to or set apart for the
holders of the Common Units or any other class or series of Units of the Trust
now or hereafter issued and outstanding to which the Series F Preferred Units
have preference or priority in the distribution of assets on any liquidation,
dissolution or winding up of the Trust, the Trustee, in its capacity as holder
of the Series F Preferred Units, shall be entitled to receive out of assets of
the Trust legally available for such purpose, liquidating distributions in the
amount of $25.00 (the "Series F Liquidation Preference") per Series F Preferred
Unit, plus an amount equal to all distributions (whether or not earned or
authorized or declared) accrued and unpaid thereon to the date of final
distribution to the Trustee, in its capacity as such holder; but the Trustee, in
its capacity as the holder of Series F Preferred Units, shall not be entitled to
any further payment. If, upon any liquidation, dissolution or winding up of the
Trust, the assets of the Trust, or proceeds thereof, distributable to the
Trustee, in its capacity as the holder of Series F Preferred Units, are
insufficient to pay in full such preferential amount with respect to the Series
F Preferred Units and the corresponding amounts with respect to all Parity
Units, then such assets, or the proceeds thereof, shall be distributed among the
Trustee, in its capacity as the holder of such Series F Preferred Units, and the
holders of all such Parity Units in proportion to the full liquidating
distributions to which they would otherwise be respectively entitled.

          (B) Subject to the rights of the holders of Units of any series or
class ranking on a parity with or senior to the Series F Preferred Units in the
distribution of assets on any liquidation, dissolution or winding up of the
Trust, upon any liquidation, dissolution or winding up the Trust, whether
voluntary or involuntary, after payment shall have been made in full to the
Trustee, in its capacity as the holder of the Series F Preferred Units, as
provided in this Section 3, the holders of any Junior Units shall, subject to
any respective terms and provisions (if any) applying thereto, be entitled to
receive any and all assets remaining to be paid or distributed, and the Trustee,
in its capacity as the holder of the Series F Preferred Units, shall not be
entitled to share therein.

          (C) For the purposes of this Section 3, (x) a consolidation or merger
of the Trust with or into one or more partnerships, limited liability companies,
corporations, real estate

                                       K-3

<PAGE>

investment trusts or other entities, (y) a sale, lease or conveyance of all or
substantially all of the Trust's property or business or (z) a share exchange
shall not be deemed to be a liquidation, dissolution or winding up of the Trust,
whether voluntary or involuntary.

     (4)  Redemption Right.
          ----------------

          (A)  Except as provided in Section 4(B), the Series F Preferred Units
are not redeemable by the Trust prior to September 27, 2004. On and after such
date, the Trustee may cause the Trust, at its option, to redeem the Series F
Preferred Units, in whole at any time or in part from time to time, for cash at
a redemption price of $25.00 per Series F Preferred Unit, plus the amounts
indicated in Section 4(A)(iii) below.

               (i)   The Series F Preferred Units shall be redeemed only if the
Trustee shall concurrently therewith redeem an equivalent number of shares of
Series F Preferred Shares for cash. Such redemption of Series F Preferred Units
shall occur substantially concurrently with the redemption by the Trustee of
such Series F Preferred Shares (such date of redemption the "Redemption Date").

               (ii)  In the event that the Trustee redeems shares of Series F
Preferred Shares for cash (including payments of cash in lieu of fractional
Shares), the Trust shall redeem a like number of Series F Preferred Units in
exchange for the amount of cash that the Trustee is required to pay pursuant to
the terms of the Series F Preferred Shares in connection with such redemption.

               (iii) Upon any redemption of Series F Preferred Units pursuant to
this Section 4, the Trust shall pay any distributions accrued and unpaid
thereon, if any, in arrears for any Distribution Period ending on or prior to
the Redemption Date. If the Redemption Date falls after a Trust Record Date and
prior to the corresponding Distribution Date, then the Trustee, in its capacity
as the holder of the Series F Preferred Units being redeemed, shall be entitled
to receive the distribution payable on the corresponding Distribution Date
notwithstanding the redemption of such Series F Preferred Units before such
Distribution Date. Except as provided above, the Trust shall make no payment or
allowance for unpaid distributions, whether or not in arrears, on Series F
Preferred Units called for redemption.

          (B)  In the event that the Trustee is required to redeem any shares of
Series F Preferred Shares pursuant to the terms thereof, the Trust shall redeem
an equivalent number of Series F Preferred Units for consideration equal to the
consideration payable by the Trustee upon redemption of such shares of Series F
Preferred Shares.

     (5)  Shares to be Retired. All Series F Preferred Units which are issued
          --------------------
and reacquired in any manner by the Trust shall be restored to the status of
authorized but unissued Units of the Trust, without designation as to class or
series.

     (6)  Conversion of Partnership Units. Upon the exercise by any limited
          -------------------------------
partner of Archstone Communities Limited Partnership-II, a Delaware limited
partnership ("ACLP-2") of its Exchange Right to exchange such partner's Series F
Preferred Limited Partnership Interests in ACLP-2 for Series F Preferred Units,
the Series F Preferred Units so issued upon exchange shall

                                       K-4

or any such partner, be converted into Series F Preferred Shares and the Trustee
shall thereafter own all of the Series F Preferred Units so issued.

     (7)  Ranking. Any class or series of Units shall be deemed to rank:
          -------

          (A) senior to the Series F Preferred Units, in the payment of
distributions or in the distribution of assets on any liquidation, dissolution
or winding up of the Trust, if the holders of such class or series of Units are
entitled to the receipt of distributions or of amounts distributable on any
liquidation, dissolution or winding up of the Trust, as the case may be, in
preference or priority to the holders of Series F Preferred Units;

          (B) on a parity with the Series F Preferred Units, in the payment of
distributions or the distribution of assets on any liquidation, dissolution or
winding up of the Trust, whether or not the distribution rates, distribution
payment dates or redemption or liquidation prices per Unit are different from
those of the Series F Preferred Units, if the holders of such class or series of
Units and the holders of Series F Preferred Units are entitled to the receipt of
distributions and amounts distributable on any liquidation, dissolution or
winding up of the Trust in proportion to their respective amounts of
distributions accrued and unpaid per Unit or liquidation preferences, without
preference or priority to each other ("Parity Units");

          (C) junior to the Series F Preferred Units, in the payment of
distributions or in the distribution of assets on any liquidation, dissolution
or winding up of the Trust, if such class or series of Units is Junior Units; an

          (D) junior to the Series F Preferred Units, in the payment of
distributions and in the distribution of assets on any liquidation, dissolution
or winding up of the Trust, if such class or series of Units is Fully Junior
Units;

     (8)  Voting. Except as required by law, the Trustee, in its capacity as the
          ------
holder of the Series F Preferred Units, shall not be entitled to vote at any
meeting of the Unitholders or for any other purpose or otherwise to participate
in any action taken by the Trust or the Unitholders, or to receive notice of any
meeting of the Unitholders.

     (9)  Restriction on Ownership. The Series F Preferred Units shall be owned
          ------------------------
and held solely by the Trustee.

     (10) General. The rights of the Trustee, in its capacity as the holder of
          -------
the Series F Preferred Units, are in addition to and not in limitation on any
other rights or authority of the Trustee, in any other capacity, under the
Agreement. In addition, nothing contained in this Exhibit K shall be deemed to
                                                  ---------
limit or otherwise restrict any rights or authority of the Trustee under the

                   DESIGNATION OF THE PREFERENCES, CONVERSION
        AND OTHER RIGHTS, VOTING POWERS, RESTRICTIONS AND LIMITATIONS AS

          -------------------
26, March 26, June 26 and September 26 of each year and ending on and including
the day preceding the first day of the next succeeding Distribution Period.

         "Fully Junior Units" shall mean the Common Units and any other class or
          ------------------
series of Units now or hereafter issued and outstanding over which the Series G
Preferred Units have a preference or priority in both (i) the payment of
dividends and (ii) the distribution of assets on any liquidation, dissolution or

          ----------
Preferred Units are issued.

     (2) Distributions.
         -------------

         (A) The Trustee, in its capacity as the holder of the then outstanding
Series G Preferred Units, shall be entitled to receive, when, as and if declared
by the Trustee, out of funds legally available therefor for such purpose, cash
distributions per Series G Preferred Unit equal to 8.625% of the Series G
Liquidation Preference (as defined below) (equivalent to $2.15625 per share) per
annum. Distributions shall begin to accrue and shall be fully cumulative from
and including the Issue Date, whether or not in any Distribution Period or
Periods there are funds of the Trust legally available for the payment of such
distributions, and shall be payable quarterly, when, as and if declared by the
Trustee, in arrears on each Distribution Date. Accrued and unpaid distributions
for any past Distribution Periods may be authorized declared and paid at any
time and for such interim periods, without reference to any regular Distribution
Date, to the Trustee, in its capacity as the holder of the Series G Preferred
Units, on such date as may be fixed by the Trustee for payment of the
corresponding dividend on the Series G Preferred Shares.

         (B) The amount of distributions for each full Distribution Period shall
be equal to $0.5390625. The distribution for any Distribution Period on the
Series G Preferred Units that represents less than a full quarter of a year
shall be computed on the basis of a 360-day year of twelve 30-day months.
Holders of Series G Preferred Units shall not be entitled to any distributions,
whether payable in cash, property or securities, in excess of cumulative
distributions, as herein provided, on the Series G Preferred Units. No interest,
or sum of money in lieu of interest, shall be payable in respect of any
distribution payment or payments on the Series G Preferred Units that may be in
arrears.

         (C) So long as any Series G Preferred Units are outstanding, no
distributions, except as described in the immediately following sentence, shall
be declared or paid or set apart for payment on any Parity Units for any period
unless (i) full cumulative distributions have been or contemporaneously are paid
or declared and a sum sufficient for the payment thereof set apart for payment
for all past Distribution Periods with respect to the Series G Preferred Units
and (ii) a sum sufficient for the payment thereof has been or contemporaneously
is set apart for payment of the distribution for the current Distribution Period
with respect to the Series G Preferred Units. When distributions are not paid in
full, or a sum sufficient for such payment is not set apart for payment, on the
Series G Preferred Units and any Parity Units as provided above, all
distributions declared on the Series G Preferred Units and all distributions
declared upon any other class or series of Parity Units shall be declared
ratably in proportion to the respective amounts of distributions accrued and
unpaid on the Series G Preferred Units and accrued and unpaid on such Parity
Units.

         (D) So long as any Series G Preferred Units are outstanding, no
distributions (other than distributions paid solely in Fully Junior Units or
options, warrants or rights to subscribe for or purchase Fully Junior Units)
shall be declared or paid or set apart for payment or other distribution shall
be declared or made on Junior Units, nor shall any Junior Units be redeemed,
purchased or otherwise acquired (other than a redemption, purchase or other
acquisition of Common Units made for purposes of an employee incentive or
benefit plan of the Trustee, the Trust or any subsidiary) for any consideration
(or any moneys be paid to or made available for a sinking fund for the
redemption of any such Junior Units) by the Trust, directly or indirectly
(except by conversion into or exchange for Fully Junior Units), unless in each
case

                                       L-2

<PAGE>

(i) full cumulative distributions have been or contemporaneously are paid or
declared and a sum sufficient for the payment thereof set apart for payment for
all past Distribution Periods with respect to the Series G Preferred Units and
all past distribution periods with respect to Parity Units and (ii) a sum
sufficient for the payment thereof has been paid or contemporaneously is set
apart for payment of the distribution for the current Distribution Period with
respect to any Parity Units. Any distribution payment on the Series G Preferred
Units shall first be credited against the earliest accrued but unpaid
distribution due which remains payable.

         (E) No distributions on the Series G Preferred Units shall be declared
by the Trustee or paid or set apart for payment by the Trust at such time as the
terms and provisions of any agreement of the Trustee or the Trust, including any
agreement relating to indebtedness of either of them, 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, payment or setting
apart for payment shall be restricted or prohibited by law.

     (3) Liquidation Preference.
         ----------------------

         (A) Upon any liquidation, dissolution or winding up of the Trust,
whether voluntary or involuntary, before any payment or distribution of the
assets of the Trust (whether capital or surplus) made to or set apart for the
holders of Common Units or any other class or series of Units of the Trust now
or hereafter issued and outstanding to which the Series G Preferred Units have
preference or priority in the distribution of assets on any liquidation,
dissolution or winding up of the Trust, the Trustee, in its capacity as holder
of the Series G Preferred Units, shall be entitled to receive out of assets of
the Trust legally available for such purpose, liquidating distributions in the
amount of $25.00 (the "Series G Liquidation Preference") per Series G Preferred
Unit, plus an amount equal to all distributions (whether or not earned or
authorized or declared) accrued and unpaid thereon to the date of final
distribution to the Trustee, in its capacity as such holder; but the Trustee, in
its capacity as the holder of Series G Preferred Units shall not be entitled to
any further payment. If, upon any liquidation, dissolution or winding up of the
Trust, the assets of the Trust, or proceeds thereof, distributable to the
Trustee, in its capacity as the holder of Series G Preferred Units, are
insufficient to pay in full such preferential amount with respect to the Series
G Preferred Units and the corresponding amounts with respect to all Parity
Units, then such assets, or the proceeds thereof, shall be distributed among the
Trustee, in its capacity as the holder of such Series G Preferred Units, and the
holders of such other Parity Units in proportion to the full liquidating
distributions to which they would otherwise be respectively entitled.

         (B) Subject to the rights of the holders of Units of any series or
class ranking on a parity with or senior to the Series G Preferred Units in the
distribution of assets on any liquidation, dissolution or winding up of the
Trust, upon any liquidation, dissolution or winding up of the Trust, after
payment has been made in full to the Trustee, in its capacity as the holder of
the Series G Preferred Units, as provided in this Section 3, the holders of any
other series or class or classes of Junior Units shall, subject to any
respective terms and provisions (if any) applying thereto, be entitled to
receive any and all assets remaining to be paid or distributed, and the Trustee,
in its capacity as the holder of the Series G Preferred Units, shall not be
entitled to share therein.

                                       L-3

<PAGE>

         (C) For the purposes of this Section 3, (x) a consolidation or merger
of the Trust with or into one or more partnerships, limited liability companies,
corporations, real estate investment trusts or other entities, (y) a sale, lease
or conveyance of all or substantially all of the Trust's property or business or
(z) a share exchange shall not be deemed to be a liquidation, dissolution or
winding up of the Trust, whether voluntary or involuntary.

     (4) Redemption Right.
         ----------------

         (A) Except as provided in Section 4(B), the Series G Preferred Units
are not redeemable prior to March 3, 2005. On and after such date, the Trustee
may cause the Trust, at its option, to redeem the Series G Preferred Units, in
whole at any time or in part from time to time, for cash at a redemption price
of $25.00 per Series G Preferred Unit, plus the amounts indicated in Section
4(A)(iii) below.

               (i)   The Series G Preferred Units shall be redeemed only if the
Trustee shall concurrently therewith redeem an equivalent number of shares of
Series G Preferred Shares for cash. Such redemption of Series G Preferred Units
shall occur substantially concurrently with the redemption by the Trustee of
such Series G Preferred Shares (such date of redemption the "Redemption Date").

               (ii)  In the event that the Trustee redeems shares of Series G
Preferred Shares for cash (including payments of cash in lieu of fractional
Shares), the Trust shall redeem a like number of Series G Preferred Units in
exchange for the amount of cash that the Trustee is required to pay pursuant to
the terms of the Series G Preferred Shares in connection with such redemption.

               (iii) Upon any redemption of Series G Preferred Units pursuant to
this Section 4, the Trust shall pay all distributions accrued and unpaid thereon
if any, in arrears for any Distribution Period ending on or prior to the
Redemption Date. If the Redemption Date falls after a Trust Record Date and
prior to the corresponding Distribution Date, then the Trustee, in its capacity
as the holder of the Series G Preferred Units being redeemed, shall be entitled
to receive the distributions payable on the corresponding Distribution Date
notwithstanding the redemption of such Series G Preferred Units before such
Distribution Date. Except as provided above, the Trust shall make no payment or
allowance for unpaid distributions, whether or not in arrears, on Series G
Preferred Units called for redemption.

         (B) In the event that the Trustee is required to redeem any shares of
Series G Preferred Shares pursuant to the terms thereof, the Trust shall redeem
an equivalent number of Series G Preferred Units for consideration equal to the
consideration payable by the Trustee upon redemption of such shares of Series G
Preferred Shares.

     (5) Shares to be Retired. All Series G Preferred Units which are issued and
         --------------------
reacquired in any manner by the Trust shall be restored to the status of
authorized but unissued Units of the Trust, without designation as to class or

or winding up of the Trust, if the holders of such class or series of Units are
entitled to the receipt of distributions or amounts distributable on any
liquidation, dissolution or winding up of the Trust, as the case may be, in
preference or priority to the holders of Series G Preferred Units;

          (B) on a parity with the Series G Preferred Units, in the payment of
distributions and in the distribution of assets on any liquidation, dissolution
or winding up of the Trust, whether or not the distribution rates, distribution
payment dates or redemption or liquidation prices per Unit thereof are different
from those of the Series G Preferred Units, if the holders of such class or
series of Units and the holders of Series G Preferred Units are entitled to the
receipt of distributions and amounts distributable on any liquidation,
dissolution or winding up of the Trust in proportion to their respective amounts
of distributions accrued and unpaid per Unit or liquidation preferences, without
preference or priority to each other ("Parity Units");

meeting of the Unitholders.

     (9)  Restriction on Ownership. The Series G Preferred Units shall be owned
          ------------------------
and held solely by the Trustee.

     (10) General. The rights of the Trustee, in its capacity as the holder of
          -------
the Series G Preferred Units, are in addition to and not in limitation on any
other rights or authority of the Trustee, in any other capacity, under the
Agreement. In addition, nothing contained in this Exhibit L shall be deemed to

                  "Fully Junior Units" shall mean the Common Units and any other
                   ------------------
class or series of Units now or hereafter issued and outstanding over which the
Series H Preferred Units have a preference or priority in both (i) the payment
of distributions and (ii) the distribution of assets on any liquidation,
dissolution or winding up of the Trust.

                  "Issue Date" shall mean the first date on which the Series H
                   ----------
Preferred Units were issued.

                  "Junior Units" shall mean the Common Units and any other
                   ------------
class or series of Units now or hereafter issued and outstanding over which the
Series H Preferred Units have a preference or priority in the payment of
distributions or in the distribution of assets on any liquidation, dissolution
or winding up of the Trust.

                  "Parity Units" has the meaning ascribed thereto in Section
                   ------------

                  "set apart for payment" shall be deemed to include, without
                   ---------------------
any action other than the following, the recording by the Trust in its
accounting ledgers of any accounting or bookkeeping entry which indicates,
pursuant to a declaration of dividends or other distribution by the Trustee, the
allocation of funds to be so paid on any series or class of Units of the Trust;
provided, however, that if any funds for any class or series of Junior Units or
--------  -------
any class or series of Units ranking on a parity with the Series H Preferred
Units as to the payment of distributions are placed in a separate account of the
Trust or delivered to a disbursing, paying or other similar agent, then "set
apart for payment" with respect to the Series H Preferred Units shall mean

                                       M-1

placing such funds in a separate account or delivering such funds to a
disbursing, paying or other similar agent.

        (2)      Distributions.
                 -------------

                 (A) The Trustee, in its capacity as the holder of the then
outstanding Series H Preferred Units, shall be entitled to receive, when, as and
if declared by the Trustee, out of funds legally available for the payment of
distributions, cumulative preferential distributions payable in cash in an
amount per Series H Preferred Unit equal to the greater of (a) 7.549% of the
Series H Liquidation Preference (as defined below) per annum (equivalent to
$2.02 per Series H Preferred Unit), or (b) the ordinary cash distributions
(determined on each Distribution Date) paid on the number of Class A-2 Units, or
portion thereof, into which a Series H Preferred Unit is convertible. The
distributions referred to in clause (b) of the preceding sentence shall equal
the number of Class A-2 Units, or portion thereof, into which a Series H
Preferred Unit is convertible, multiplied by the most recent quarterly
distribution on a Class A-2 Unit on or before the applicable Distribution Date.
If the Trust pays an ordinary cash distribution on the Class A-2 Units with
respect to a Distribution Period after the date on which the Distribution Date
is declared pursuant to clause (ii) of the definition of Distribution Date and
the distribution calculated with respect to clause (b) of the first sentence of
this Section 2(A) is greater than the distribution previously declared on the
Series H Preferred Units with respect to such Distribution Period, the Trust
shall pay an additional distribution in respect of the Series H Preferred Units
on the date on which the distribution on the Class A-2 Units is paid, in an
amount equal to the difference between (y) the distribution calculated pursuant
to clause (b) of the first sentence of this Section 2(A) and (z) the amount of
distributions previously declared on the Series H Preferred Units with respect
to such Distribution Period. Distributions shall begin to accrue and shall be
fully cumulative from October 1, 2001, whether or not in any Distribution Period
or Periods there shall be funds of the Trust legally available for the payment
of such distributions, and shall be payable quarterly, when, as and if declared
by the Trustee, in arrears on each Distribution Date. Accrued and unpaid
distributions for any past Distribution Periods may be declared and paid at any
time and for such interim periods, without reference to any regular Distribution
Date, to the Trustee, in its capacity as the holder of the Series H Preferred
Units, on such date as may be fixed by the Trustee for payment of the
corresponding dividend on the Series H Preferred Shares. Any distribution made
on the Series H Preferred Units shall first be credited against the earliest
accrued but unpaid distribution due with respect to Series H Preferred Units
which remains payable.

                 (B) The amount of distributions for each full Distribution
Period shall be equal to $0.505. The amount of distribution for any Distribution
Period on the Series H Preferred Units that represents less than a full quarter
of a year shall be computed on the basis of a 360-day year of twelve 30-day
months. No interest, or sum of money in lieu of interest, shall be payable in
respect of any distribution payment or payments on the Series H Preferred Units
that may be in arrears.

                 (C) So long as any Series H Preferred Units are outstanding,
no distributions, except as described in the immediately following sentence,
shall be declared or paid or set apart for payment on any class or series of
Parity Units for any period unless full cumulative distributions have been or
contemporaneously are declared and paid or declared and a sum

                                       M-2

<PAGE>

sufficient for the payment thereof set apart for such payment on the Series H
Preferred Units for all Distribution Periods terminating on or prior to the
distribution payment date for such class or series of Parity Units. When
distributions are not paid full or a sum sufficient for such payment is not set
apart, as aforesaid, all distributions declared upon Series H Preferred Units
and all distributions declared upon any other class or series of Parity Units
shall be declared ratably in proportion to the respective amounts of
distributions accumulated and unpaid on the Series H Preferred Units and
accumulated and unpaid on such Parity Units.

                  (D) So long as any Series H Preferred Units are outstanding,
no distributions (other than distributions paid solely in Fully Junior Units or
options, warrants or rights to subscribe for or purchase Fully Junior Units)
shall be declared or paid or set apart for payment or other distribution shall
be declared or made or set apart for payment upon Junior Units, nor shall any
Junior Units be redeemed, purchased or otherwise acquired (other than a
redemption, purchase or other acquisition of Common Units made for purposes of
an employee incentive or benefit plan of the Trustee, the Trust or any
subsidiary) for any consideration (or any moneys be paid to or made available
for a sinking fund for the redemption of any such Junior Units) by the Trust,
directly or indirectly (except by conversion into or exchange for Fully Junior
Units), unless in each case (i) the full cumulative distributions on all
outstanding Series H Preferred Units and any other Parity Units of the Trust
shall have been paid or declared and set apart for payment for all past
Distribution Periods with respect to the Series H Preferred Units and all past
distribution periods with respect to such Parity Units and (ii) sufficient funds
shall have been paid or set apart for the payment of the distribution for the
current Distribution Period with respect to the Series H Preferred Units and the
current distribution period with respect to such Parity Units.

                  (E) No distributions on the Series H Preferred Units shall be
declared by the Trustee or paid or set apart for payment by the Trust at such
time as the terms and provisions of any agreement of the Trustee or the Trust,
including any agreement relating to indebtedness of either of them, 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.

         (3)      Liquidation Preference.
                  ----------------------
                  (A) In the event of any liquidation, dissolution or winding up
of the Trust, whether voluntary or involuntary, before any payment or
distribution of the assets of the Trust shall be made to or set apart for the
holders of Junior Units, the Trustee, in its capacity as holder of the Series H
Preferred Units, shall be entitled to receive Twenty Seven Dollars and Eight
Cents ($27.08) (the "Series H Liquidation Preference") per Series H Preferred
Unit plus an amount equal to all distributions (whether or not earned or
declared) accrued and unpaid thereon to the date of final distribution to the
Trustee, in its capacity as such holder; but the Trustee, in its capacity as the
holder of Series H Preferred Units shall not be entitled to any further payment;
provided that the distribution payable with respect to the Distribution Period
containing the date of final distribution shall be equal to the greater of (i)
the distribution provided in clause (a) of the first sentence of Section 2(A) or
(ii) the distribution determined pursuant to clause (b) of the first sentence of
Section 2(A) for the preceding Distribution Period. If, upon any such
liquidation, dissolution or winding up of the Trust, the assets of the Trust, or
proceeds thereof,

                                       M-3

<PAGE>

distributable to the Trustee, in its capacity as the holder of Series H
Preferred Units, shall be insufficient to pay in full the preferential amount
aforesaid and liquidating payments on any other class or series of Parity Units,
then such assets, or the proceeds thereof, shall be distributed among the
Trustee, in its capacity as the holder of such Series H Preferred Units, and the
holders of such other Parity Units ratably in accordance with the respective
amounts that would be payable on such Series H Preferred Units and such other
Parity Units if all amounts payable thereon were paid in full. For the purposes
of this Section 3, (x) a consolidation or merger of the Trust with one or more
partnerships, limited liability companies, corporations, real estate investment
trusts or other entities, (y) a sale, lease or conveyance of all or
substantially all of the Trust's property or business or (z) a share exchange
shall not be deemed to be a liquidation, dissolution or winding up, voluntary or
involuntary, of the Trust.

                  (B) Subject to the rights of the holders of Units of any
series or class ranking on a parity with or prior to the Series H Preferred
Units upon any liquidation, dissolution or winding up of the Trust, after
payment shall have been made in full to the Trustee, in its capacity as the
holder of the Series H Preferred Units, as provided in this Section 3, any other
series or class or classes of Junior Units shall, subject to any respective
terms and provisions applying thereto, be entitled to receive any and all assets
remaining to be paid or distributed, and the Trustee, in its capacity as the
holder of the Series H Preferred Units, shall not be entitled to share therein.

         (4)      Redemption Right.
                  ----------------
                  (A) Except as provided in Section 4(B), the Series H Preferred
Units shall not be redeemable prior to May 15, 2003. On and after May 15, 2003,
the Trustee may cause the Trust, at its option, to redeem the Series H Preferred
Units, from funds legally available therefor, in whole at any time or from time
to time in part, (x) for Class A-2 Units, subject to the conditions set forth in
paragraph (i) below, or (y) for cash in an amount per Series H Preferred Unit
equal to the Series H Liquidation Preference plus accrued and unpaid
distributions (the "Redemption Price"), in each case subject to the conditions
set forth below.

                      (i)      The Series H Preferred Units shall be redeemed
only if the Trustee shall concurrently therewith redeem an equivalent number of
shares of Series H Preferred Shares for Shares or cash, as the case may be.
Such redemption of Series H Preferred Units shall occur substantially
concurrently with the redemption by the Trustee of such Series H Preferred
Shares (such date of redemption the "Redemption Date").

                      (ii)     In the event that the Trustee redeems shares of
Series H Preferred Shares in exchange for Shares, an equivalent number of Series
H Preferred Units shall be converted into a number of Class A-2 Units equal to
(x) the number of Shares issued by the Trustee in redemption of such shares of
Series H Preferred Shares divided by (y) the Conversion Factor.

                      (iii)    In the event that the Trustee redeems shares of
Series H Preferred Shares for cash (including payments of cash in lieu of
fractional Shares), the Trust shall redeem a like number of Series H Preferred
Units in exchange for the amount of cash that the Trustee is

                                       M-4

<PAGE>

required to pay pursuant to the terms of the Series H Preferred Shares in
connection with such redemption.

                (iv) Upon any redemption of Series H Preferred Units pursuant to
this Section 4, the Trust shall pay all accrued and unpaid distributions
thereon, if any, to the Redemption Date, without interest. If the Redemption
Date falls after a Trust Record Date and prior to the corresponding Distribution
Date, then the Trustee, in its capacity as the holder of the Series H Preferred
Units being redeemed, shall be entitled to distributions payable on the
corresponding Distribution Date notwithstanding the redemption of such Series H
Preferred Units before such Distribution Date. Except as provided above, the
Trust shall make no payment or allowance for unpaid distributions, whether or
not in arrears, on Series H Preferred Units called for redemption.

                (v) Any Class A-2 Unit issued upon redemption of the Series H
Preferred Units shall be validly issued, fully paid and non-assessable.

             (B) In the event that the Trustee is required to redeem any shares
of Series H Preferred Shares pursuant to the terms thereof, the Trust shall
redeem an equivalent number of Series H Preferred Units for consideration equal
to the consideration payable by the Trustee upon redemption of such shares of
Series H Preferred Shares.

         (5) Shares to be Retired. All Series H Preferred Units which are issued
             --------------------
and reacquired in any manner by the Trust shall be restored to the status of
authorized but unissued Units of the Trust, without designation as to class or
series.

         (6) Conversion to Class A-2 Units.
             -----------------------------

             (A) In the event that a holder of Series H Preferred Shares
exercises its right to convert such Series H Preferred Shares into Shares, then,
concurrently therewith, an equivalent number of Series H Preferred Units shall
be automatically converted into a number of Class A-2 Units equal to (x) the
number of Shares issued upon conversion of such Series H Preferred Shares
divided by (y) the Conversion Factor. Any such conversion will be effective at
the same time as the conversion of Series H Preferred Shares into Shares is
effective.

             (B) The Trustee, in its capacity as the holder of Series H
Preferred Units that are converted pursuant to this Section 4 effective during
the period after a Trust Record Date and prior to the opening of business on the
corresponding Distribution Date, shall not be entitled to receive the
distribution payable on such Series H Preferred Units on such Distribution Date
notwithstanding such conversion thereof following the corresponding Trust Record
Date and prior to such Distribution Date.

payment of distributions and in the distribution of assets upon liquidation,
dissolution or winding up of the Trust, whether or not the distribution rates,
distribution payment dates or redemption or liquidation prices per Unit are
different from those of the Series H Preferred Units, if the holders of such
class or series of Units and the holders of the Series H Preferred Units are
entitled to the receipt of distributions and of amounts distributable upon any
liquidation, dissolution or winding up of the Trust in proportion to their
respective amounts of distributions accrued and unpaid per Unit or liquidation
preferences, without preference or priority to each other ("Parity Units");

                  (C) junior to the Series H Preferred Units, in the payment of
distributions or in the distribution of assets upon any liquidation, dissolution
or winding up of the Trust, if such class or series of Units is Junior Units; an

                  (D) junior to the Series H Preferred Units, in the payment of

         (10)     General.  The rights of the Trustee, in its capacity as the
                  -------
holder of the Series H Preferred Units, are in addition to and not in limitation
on any other rights or authority of the Trustee, in any other capacity, under
the Agreement. In addition, nothing contained in this Exhibit M shall be deemed
                                                      ---------
to limit or otherwise restrict any rights or authority of the Trustee under the
Agreement, other than in its capacity as the holder of the Series H Preferred

     (2)  Distributions.
          -------------

          (A) The Trustee, in its capacity as the holder of the then outstanding

be fixed by the Trustee for payment of the corresponding dividend on the Series
I Preferred Shares. Any distribution made on the Series I Preferred Units shall

respect to Series I Preferred Units which remains payable.

          (B) The amount of distributions for each full Distribution Period
relating to the Series I Preferred Units shall be equal to $1,915. The amount of
distribution for any period on the Series I Preferred Units that represents less

be payable in respect of any distribution payment or payments on the Series I
Preferred Units that may be in arrears.

          (C) So long as any Series I Preferred Units are outstanding, no
distributions, except as described in the immediately following sentence, shall
be declared or paid or set apart for payment on any class or series of Parity
Units for any period unless full cumulative distributions have been or
contemporaneously are declared and paid or declared and a sum sufficient for the
payment thereof set apart for such payment on the Series I Preferred Units for
all Distribution Periods terminating on or prior to the distribution payment
date for such class or series of Parity Units. When distributions are not paid
in full or a sum sufficient for such payment is not set apart, as aforesaid, all
distributions declared upon Series I Preferred Units and all distributions
declared upon any other class or series of Parity Units shall be declared
ratably in proportion to the respective amounts of distributions accumulated and
unpaid on the Series I Preferred Units and accumulated and unpaid on such Parity
Units.

          (D) So long as any Series I Preferred Units are outstanding, no
distributions (other than distributions paid solely in Fully Junior Units or
options, warrants or rights to subscribe for or purchase Fully Junior Units)
shall be declared or paid or set apart for payment or other distribution shall
be declared or made or set apart for payment upon Junior Units, nor shall any
Junior Units be redeemed, purchased or otherwise acquired (other than a

subsidiary) for any consideration (or any moneys be paid to or made available
for a sinking fund for the redemption of any such Junior Units) by the Trust,
directly or indirectly (except by conversion into or exchange for Fully Junior
Units), unless in each case (i) the full cumulative distributions on all
outstanding Series I Preferred Units and any other Parity Units of the Trust
shall have been paid or declared and set apart for payment

and all past distribution periods with respect to such Parity Units and (ii)
sufficient funds shall have been paid or set apart for the payment of the
distribution for the current Distribution Period with respect to the Series I
Preferred Units and the current distribution period with respect to such Parity
Units.

          (F) No distributions on the Series I Preferred Units shall be declared
by the Trustee or paid or set apart for payment by the Trust at such time as the
terms and provisions of any agreement of the Trustee or the Trust, including any
agreement relating to indebtedness of either of them, 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.

     (3)  Liquidation Preference.
          ----------------------

          (A) In the event of any liquidation, dissolution or winding up of the
Trust, whether voluntary or involuntary, before any payment or distribution of
the assets of the Trust shall be made to or set apart for the holders of Junior
Units, the Trustee, in its capacity as holder of the Series I Preferred Units,
shall be entitled to the sum of (i) $100,000 per Series I Preferred Unit (the
"Series I Liquidation Preference") plus (ii) an amount equal to all
distributions (whether or not earned or declared) accrued and unpaid thereon to
the date of final distribution to the Trustee, in its capacity as such holder;
but the Trustee, in its capacity as the holder of Series I Preferred Units shall
not be entitled to any further payment. If, upon any such liquidation,
dissolution or winding up of the Trust, the assets of the Trust, or proceeds
thereof, distributable to the Trustee, in its capacity as the holder of Series I
Preferred Units, shall be insufficient to pay in full the preferential amount
aforesaid and liquidating payments on any other class or series of Parity Units,
then such assets, or the proceeds thereof, shall be distributed among the
Trustee, in its capacity as the holder of such Series I Preferred Units, and the
holders of such other Parity Units ratably in accordance with the respective
amounts that would be payable on such Series I Preferred Units and such other
Parity Units if all amounts payable thereon were paid in full. For the purposes
of this Section 3, (x) a consolidation or merger of the Trust with one or more
partnerships, limited liability companies, corporations, real estate investment
trusts or other entities, (y) a sale, lease or conveyance of all or
substantially all of the Trust's property or business or (z) a share exchange
shall not be deemed to be a liquidation, dissolution or winding up, voluntary or
involuntary, of the Trust.

          (B) Subject to the rights of the holders of Units of any series or
class or classes of Units ranking on a parity with or prior to the Series I
Preferred Units upon any liquidation, dissolution or winding up of the Trust,
upon any liquidation, dissolution or winding up of the Trust, after payment
shall have been made in full to the Trustee, in its capacity as the holder of
the Series I Preferred Units, as provided in this Section 3, any other series or
class or classes of Junior Units shall, subject to the respective terms and
provisions (if any) applying thereto, be entitled to receive any and all assets
remaining to be paid or distributed, and the Trustee, in its capacity as the
holder of the Series I Preferred Units, shall not be entitled to share therein.

                   DESIGNATION OF THE PREFERENCES, CONVERSION
       AND OTHER RIGHTS, VOTING POWERS, RESTRICTIONS AND LIMITATIONS AS TO
                            SERIES J PREFERRED UNITS

     The Series J Preferred Units shall have the following designations,
preferences, rights, powers and duties:

     (1)  Certain Defined Terms. The following capitalized terms used in this
          ---------------------
Exhibit O shall have the respective meanings set forth below:
---------

          "Distribution Date" means (i) for any Distribution Period with respect
           -----------------
to which the Trust pays a distribution on the Class A Units, the date on which
such distribution is paid, or (ii) for any Distribution Period with respect to
which the Trust does not pay a distribution on the Class A Units, the date set
by the Trustee for payment of dividends on the Series J Preferred Shares, which
date shall not be later than the forty-fifth calendar day after the end of the
applicable Distribution Period.

          "Distribution Period" means quarterly periods commencing on January 1,
           -------------------
April 1, July 1 and October 1 of each year and ending on and including the day
preceding the first day of the next succeeding Distribution Period (other than
the Distribution Period during which any Series J Preferred Units shall be
redeemed pursuant to Section 4, which shall end on and include the date of such
redemption).

          "Fully Junior Units" shall mean the Common Units and any other class
           ------------------
or series of Units now or hereafter issued and outstanding over which the Series
J Preferred Units have preference or priority in both (i) the payment of
dividends and (ii) the distribution of assets on any liquidation, dissolution or
winding up of the Trust.

          "Issue Date" shall mean the first date on which the first Series J
           ----------
Preferred Units were issued.

          "Junior Units" shall mean the Common Units and any other class or
           ------------
series of Units now or hereafter issued and outstanding over which the Series J
Preferred Units have preference or priority in the payment of dividends or in
the distribution of assets on any liquidation, dissolution or winding up of the
Trust.

          "set apart for payment" shall be deemed to include, without any action
           ---------------------
other than the following, the recording by the Trust in its accounting ledgers

however, that if any funds for any class or series of Junior Units or any class
-------
or series of Units ranking on a parity with the Series J Preferred Units as to
the payment of distributions are placed in a separate account of the Trust or
delivered to a disbursing, paying or other similar agent, then "set apart for
payment" with respect to the Series J Preferred Units shall mean placing such
funds in a separate account or delivering such funds to a disbursing, paying or

                                       O-1

<PAGE>

          "Parity Units" has the meaning ascribed thereto in Section 7(B).
           ------------

     (2)  Distributions.
          -------------

          (A)  The Trustee, in its capacity as the holder of the then
outstanding Series J Preferred Units, shall be entitled to receive, when, as and
if declared by the Trustee, out of funds legally available for the payment of
distributions, cumulative preferential distributions payable in cash in an
amount per Series J Preferred Unit equal to the greater of (a) $3.1025 per
annum, or (b) the ordinary cash distributions (determined on each Distribution
Date) paid on the number of Class A-2 Units, or portion thereof, into which a
Series J Preferred Unit is convertible. The distributions referred to in clause
(b) of the preceding sentence shall equal the number of Class A-2 Units, or
portion thereof, into which a Series J Preferred Unit is convertible, multiplied
by the most recent quarterly distribution on a Class A-2 Unit on or before the
applicable Distribution Date. If the Trust pays an ordinary cash distribution on
the Class A-2 Units with respect to a Distribution Period after the date on
which the Distribution Date is declared pursuant to clause (ii) of the
definition of Distribution Date and the distribution calculated with respect to
clause (b) of the first sentence of this Section 2(A) is greater than the
distribution previously declared on the Series J Preferred Units with respect to
such Distribution Period, the Trust shall pay an additional distribution in
respect of the Series J Preferred Units on the date on which the distribution on
the Class A-2 Units is paid, in an amount equal to the difference between (y)
the distribution calculated pursuant to clause (b) of the first sentence of this
Section 2(A) and (z) the amount of distributions previously declared on the
Series J Preferred Units with respect to such Distribution Period. Distributions
shall begin to accrue and shall be fully cumulative from October 1, 2001,
whether or not in any Distribution Period or Periods there shall be funds of the
Trust legally available for the payment of such distributions, and shall be
payable quarterly, when, as and if declared by the Trustee, in arrears on
Distribution Dates. Accrued and unpaid distributions for any past Distribution
Periods may be declared and paid at any time and for such interim periods,
without reference to any regular Distribution Date, to the Trustee, in its
capacity as the holder of the Series J Preferred Units, on such date as may be
fixed by the Trustee for payment of the corresponding dividend on the Series J
Preferred Shares. Any distribution made on the Series J Preferred Units shall
first be credited against the earliest accrued but unpaid distribution due with
respect to Series J Preferred Units which remains payable.

          (B)  The amount of distributions referred to in clause (a) of the
first sentence of Section 2(A) for each full Distribution Period shall be
$0.775625. The amount of distributions payable for any period shorter than a
full Distribution Period, on the Series J Preferred Units shall be computed on
the basis of a 360-day year of twelve 30-day months. No interest, or sum of
money in lieu of interest, shall be payable in respect of any distribution
payment or payments on the Series J Preferred Units that may be in arrears.

          (C)  So long as any Series J Preferred Units are outstanding, no
distributions, except as described in the immediately following sentence, shall
be declared or paid or set apart for payment on any class or series of Parity
Units for any period unless full cumulative distributions have been or
contemporaneously are declared and paid or declared and a sum sufficient for the
payment thereof set apart for such payment on the Series J Preferred Units for
all Distribution Periods terminating on or prior to the distribution payment
date for such class or series of Parity Units. When distributions are not paid
in full or a sum sufficient for such

                                       O-2

<PAGE>

payment is not set apart, as aforesaid, all distributions declared upon Series J
Preferred Units and all distributions declared upon any other class or series of
Parity Units shall be declared ratably in proportion to the respective amounts
of distributions accumulated and unpaid on the Series J Preferred Units and
accumulated and unpaid on such Parity Units.

          (D)  So long as any Series J Preferred Units are outstanding, no
distributions (other than distributions paid solely in Fully Junior Units or
options, warrants or rights to subscribe for or purchase Fully Junior Units)
shall be declared or paid or set apart for payment or other distribution shall
be declared or made or set apart for payment upon Junior Units, nor shall any
Junior Units be redeemed, purchased or otherwise acquired (other than a
redemption, purchase or other acquisition of Common Units made for purposes of
an employee incentive or benefit plan of the Trustee, the Trust or any
subsidiary) for any consideration (or any moneys be paid to or made available
for a sinking fund for the redemption of any such Junior Units) by the Trust,
directly or indirectly (except by conversion into or exchange for Fully Junior
Units), unless in each case (i) the full cumulative distributions on all
outstanding Series J Preferred Units and any other Parity Units of the Trust
shall have been paid or declared and set apart for payment for all past
Distribution Periods with respect to the Series J Preferred Units and all past
distribution periods with respect to such Parity Units and (ii) sufficient funds
shall have been paid or set apart for the payment of the distribution for the
current Distribution Period with respect to the Series J Preferred Units and the
current distribution period with respect to such Parity Units.

          (E)  No distributions on the Series J Preferred Units shall be
declared by the Trustee or paid or set apart for payment by the Trust at such
time as the terms and provisions of any agreement of the Trustee or the Trust,
including any agreement relating to indebtedness of either of them, 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.

     (3)  Liquidation Preference.
          ----------------------

          (A)  In the event of any liquidation, dissolution or winding up of
the Trust, whether voluntary or involuntary, before any payment or distribution
of the assets of the Trust shall be made to or set apart for the holders of
Junior Units, the Trustee, in its capacity as holder of the Series J Preferred
Units, shall be entitled to receive Thirty-Six Dollars and Fifty Cents ($36.50)
(the "Series J Liquidation Preference") per Series J Preferred Unit plus an
amount equal to all distributions (whether or not earned or declared) accrued
and unpaid thereon to the date of final distribution to the Trustee, in its
capacity as such holder; but the Trustee, in its capacity as the holder of
Series J Preferred Units, shall not be entitled to any further payment; provided
that the distribution payable with respect to the Distribution Period containing
the date of final distribution shall be equal to the greater of (i) the
distribution provided in clause (a) of the first sentence of Section 2(A) or
(ii) the distribution determined pursuant to clause (b) of the first sentence of
Section 2(A) for the preceding Distribution Period. If, upon any liquidation,
dissolution or winding up of the Trust, the assets of the Trust, or proceeds
thereof, distributable to the Trustee, in its capacity as the holder of Series J
Preferred Units, shall be insufficient to pay in full the preferential amount
aforesaid and liquidating payments on any other class or series of Parity Units,
then such assets, or the proceeds thereof, shall be distributed among the
Trustee, in

                                       O-3

<PAGE>

its capacity as the holder of such Series J Preferred Units, and the holders of
such other Parity Units ratably in accordance with the respective amounts that
would be payable on such Series J Preferred Units and such other Parity Units if
all amounts payable thereon were paid in full. For the purposes of this Section
3, (x) a consolidation or merger of the Trust with one or more partnerships,
limited liability companies, corporations, real estate investment trusts or
other entities, (y) a sale, lease or conveyance of all or substantially all of
the Trust's property or business or (z) a share exchange shall not be deemed to
be a liquidation, dissolution or winding up, voluntary or involuntary, of the
Trust.

          (B)  Subject to the rights of the holders of Units of any series or
class ranking on a parity with or prior to the Series J Preferred Units upon any
liquidation, dissolution or winding up of the Trust, after payment shall have
been made in full to the Trustee, in its capacity as the holder of the Series J
Preferred Units, as provided in this Section 3, any other series or class or
classes of Junior Units shall, subject to any respective terms and provisions
(if any) applying thereto, be entitled to receive any and all assets remaining
to be paid or distributed, and the Trustee, in its capacity as the holder of the
Series J Preferred Units, shall not be entitled to share therein.

     (4)  Redemption Right.
          ---------------

          (A)  Except as provided in Section 4(B), the Series J Preferred Units
shall not be redeemable by the Trust prior to July 13, 2002. On and after July
13, 2002, the Trustee may cause the Trust, at its option, to redeem the Series J
Preferred Units, in whole at any time or from time to time in part, from funds
legally available therefor, (x) for Class A-2 Units, subject to the conditions
set forth in paragraph (i) below, or (y) for cash in an amount per Series J
Preferred Unit equal to the Series J Liquidation Preference plus accrued and
unpaid distributions (the "Redemption Price"), in each case subject to the
conditions set forth below.

               (i)   The Series J Preferred Units shall be redeemed only if the
Trustee shall concurrently therewith redeem an equivalent number of shares of
Series J Preferred Shares for Shares or cash, as the case may be. Such
redemption of Series J Preferred Units shall occur substantially concurrently
with the redemption by the Trustee of such Series J Preferred Shares (such date
of redemption the "Redemption Date").

               (ii)  In the event that the Trustee redeems shares of Series J
Preferred Shares in exchange for Shares, an equivalent number of Series J
Preferred Units shall be converted into a number of Class A-2 Units equal to (x)
the number of Shares issued by the Trustee in redemption of such shares of
Series J Preferred Shares divided by (y) the Conversion Factor.

               (iii) In the event that the Trustee redeems shares of Series J
Preferred Shares for cash (including payments of cash in lieu of fractional
Shares), the Trust shall redeem a like number of Series J Preferred Units in
exchange for the amount of cash that the Trustee is required to pay pursuant to
the terms of the Series J Preferred Shares in connection with such redemption.

                                       O-4

<PAGE>
               (iv) Upon any redemption of Series J Preferred Units pursuant to
this Section 4, the Trust shall pay any accrued and unpaid distributions if any,
thereon to the Redemption Date, without interest. If the Redemption Date falls
after a Trust Record Date and prior to the corresponding Distribution Date, then
the Trustee, in its capacity as the holder of the Series J Preferred Units being
redeemed, shall be entitled to distributions payable on the corresponding
Distribution Date notwithstanding the redemption of such Series J Preferred
Units before such Distribution Date. Except as provided above, the Trust shall
make no payment or allowance for unpaid distributions, whether or not in
arrears, on Series J Preferred Units called for redemption.

               (v)  Any Class A-2 Unit issued upon redemption of the Series J
Preferred Units shall be validly issued, fully paid and non-assessable.

          (B)  In the event that the Trustee is required to redeem any shares of
Series J Preferred Shares pursuant to the terms thereof, the Trust shall redeem
an equivalent number of Series J Preferred Units for consideration equal to the
consideration payable by the Trustee upon redemption of such shares of Series J
Preferred Shares.

     (5)  Shares to be Retired. All Series J Preferred Units which are issued
          --------------------
and reacquired in any manner by the Trust shall be restored to the status of
authorized but unissued Units of the Trust, without designation as to class or
series.

     (6)  Conversion to Class A-2 Units.
          -----------------------------

          (A)  In the event that a holder of Series J Preferred Shares exercises
its right to convert such Series J Preferred Shares into Shares, then,
concurrently therewith, an equivalent number of Series J Preferred Units shall
be automatically converted into a number of Class A-2 Units equal to (x) the
number of Shares issued upon conversion of such Series J Preferred Shares
divided by (y) the Conversion Factor. Any such conversion will be effective at
the same time as the conversion of Series J Preferred Shares into Shares is
effective.

          (B)  The Trustee, in its capacity as the holder of Series J Preferred
Units that are converted pursuant to this Section 5 effective during the period
after a Trust Record Date and prior to the opening of business on the
corresponding Distribution Date, shall not be entitled to receive the
distribution payable on such Series J Preferred Units on such Distribution Date
notwithstanding such conversion thereof following the corresponding Trust Record
Date and prior to such Distribution Date.

     (7)  Ranking. Any class or series of Units shall be deemed to rank:
          -------

          (A)  senior to the Series J Preferred Units, in the payment of
distributions or in the distribution of assets upon liquidation, dissolution or
winding up of the Trust, if the holders of such class or series of Units are
entitled to the receipt of distributions or of amounts distributable upon any
liquidation, dissolution or winding up of the Trust, as the case may be, in
preference or priority to the holders of Series J Preferred Units;

          (B)  on a parity with the Series J Preferred Units, in the payment of
distributions and in the distribution of assets upon liquidation, dissolution or
winding up of the

                                       O-5

<PAGE>

Trust, whether or not the distribution rates, distribution payment dates or
redemption or liquidation prices per Unit be different from those of the Series
J Preferred Units, if the holders of such class or series of Units and the
Series J Preferred Units are entitled to the receipt of distributions and of
amounts distributable upon any liquidation, dissolution or winding up in
proportion to their respective amounts of accrued and unpaid distributions per
Unit or liquidation preferences, without preference or priority to each other
("Parity Units");

          (C)  junior to the Series J Preferred Units, in the payment of
distributions or in the distribution of assets upon any liquidation, dissolution
or winding up of the Trust, if such class or series of Units is Junior Units;
and

          (D)  junior to the Series J Preferred Units, in the payment of
distributions and in the distribution of assets upon any liquidation,

respect to Series K Preferred Units which remains payable.

          (B)  The amount of distributions referred to in clause (a) of the
first sentence of Section 2(A) shall be equal to the annual distribution rate
payable for each full Distribution Period for the Series K Preferred Units shall
be computed by dividing the applicable rate by four. The amount of distributions
payable for any period shorter than a full Distribution Period, on the Series K
Preferred Units shall be computed on the basis of a 360-day year of twelve
30-day months. No interest, or sum of money in lieu of interest, shall be
payable in respect of any distribution payment or payments on the Series K
Preferred Units that may be in arrears.

          (C)  So long as any Series K Preferred Units are outstanding, no
distributions, except as described in the immediately following sentence, shall
be declared or paid or set apart for payment on any class or series of Parity
Units for any period unless full cumulative distributions have been or
contemporaneously are declared and paid or declared and a sum sufficient for the
payment thereof set apart for such payment on the Series K Preferred Units for

                                       P-2

<PAGE>

all Distribution Periods terminating on or prior to the distribution payment
date for such class or series of Parity Units. When distributions are not paid
in full or a sum sufficient for such payment is not set apart, as aforesaid, all
distributions declared upon Series K Preferred Units and all distributions
declared upon any other class or series of Parity Units shall be declared
ratably in proportion to the respective amounts of distributions accumulated and
unpaid on the Series K Preferred Units and accumulated and unpaid on such Parity
Units.

          (D)  So long as any Series K Preferred Units are outstanding, no
distributions (other than distributions paid solely in Fully Junior Units or
options, warrants or rights to subscribe for or purchase Fully Junior Units)
shall be declared or paid or set apart for payment or other distribution shall
be declared or made or set apart for payment upon Junior Units, nor shall any
Junior Units be redeemed, purchased or otherwise acquired (other than a
redemption, purchase or other acquisition of Common Units made for purposes of
an employee incentive or benefit plan of the Trustee, the Trust or any
subsidiary) for any consideration (or any moneys be paid to or made available
for a sinking fund for the redemption of any such Junior Units) by the Trust,
directly or indirectly (except by conversion into or exchange for Fully Junior
Units), unless in each case (i) the full cumulative distributions on all
outstanding Series K Preferred Units and any other Parity Units of the Trust
shall have been paid or declared and set apart for payment for all past
Distribution Periods with respect to the Series K Preferred Units and all past
distribution periods with respect to such Parity Units and (ii) sufficient funds
shall have been paid or set apart for the payment of the distribution for the
current Distribution Period with respect to the Series K Preferred Units and the
current distribution period with respect to such Parity Units.

          (E)  No distributions on the Series K Preferred Units shall be
declared by the Trustee or paid or set apart for payment by the Trust at such
time as the terms and provisions of any agreement of the Trustee or the Trust,
including any agreement relating to indebtedness of either of them, 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.

     (3)  Liquidation Preference.
          ----------------------

          (A)  In the event of any liquidation, dissolution or winding up of the
Trust, whether voluntary or involuntary, before any payment or distribution of
the assets of the Trust shall be made to or set apart for the holders of Junior
Units, the Trustee, in its capacity as holder of the Series K Preferred Units,
shall be entitled to receive Thirty-Seven Dollars and Fifty Cents ($37.50) (the
"Series K Liquidation Preference") per Series K Preferred Unit plus an amount
equal to all distributions (whether or not earned or declared) accrued and
unpaid thereon to the date of final distribution to the Trustee, in its capacity
as such holder; but the Trustee, in its capacity as the holder of Series K
Preferred Units, shall not be entitled to any further payment; provided that the
distribution payable with respect to the Distribution Period containing the date
of final distribution shall be equal to the greater of (i) the distribution
provided in clause (a) of the first sentence of Section 2(A) or (ii) the
distribution determined pursuant to clause (b) of the first sentence of Section
2(A) for the preceding Distribution Period. If, upon any liquidation,
dissolution or winding up of the Trust, the assets of the Trust, or proceeds
thereof, distributable to the Trustee, in its capacity as the holder of Series K
Preferred Units, shall be insufficient to

                                       P-3

<PAGE>

pay in full the preferential amount aforesaid and liquidating payments on any
other class or series of Parity Units, then such assets, or the proceeds
thereof, shall be distributed among the Trustee, in its capacity as the holder
of such Series K Preferred Units, and the holders of such other Parity Units
ratably in accordance with the respective amounts that would be payable on such
Series K Preferred Units and such other Parity Units if all amounts payable
thereon were paid in full. For the purposes of this Section 3, (x) a
consolidation or merger of the Trust with one or more partnerships, limited
liability companies, corporations, real estate investment trusts or other
entities, (y) a sale, lease or conveyance of all or substantially all of the
Trust's property or business or (z) a share exchange shall not be deemed to be a
liquidation, dissolution or winding up, voluntary or involuntary, of the Trust.

          (B) Subject to the rights of the holders of Units of any series or
class ranking on a parity with or prior to the Series K Preferred Units upon any
liquidation, dissolution or winding up of the Trust, after payment shall have
been made in full to the Trustee, in its capacity as the holder of the Series K
Preferred Units, as provided in this Section 3, any other series or class or
classes of Junior Units shall, subject to any respective terms and provisions
(if any) applying thereto, be entitled to receive any and all assets remaining
to be paid or distributed, and the Trustee, in its capacity as the holder of the
Series K Preferred Units, shall not be entitled to share therein.

     (4)  Redemption Right.
          ----------------

          (A)  Except as provided in Section 4(B), the Series K Preferred Units
shall not be redeemable by the Trust prior to October 1, 2004. On and after
October 1, 2004, the Trustee may cause the Trust, at its option, to redeem the
Series K Preferred Units, in whole at any time or from time to time in part,
from funds legally available therefor, (x) for Class A-2 Units, subject to the
conditions set forth in paragraph (i) below, or (y) for cash in an amount per
Series K Preferred Unit equal to the Series K Liquidation Preference plus
accrued and unpaid distributions (the "Redemption Price"), in each case subject
to the conditions set forth below.

               (i)    The Series K Preferred Units shall be redeemed only if the
Trustee shall concurrently therewith redeem an equivalent number of shares of
Series K Preferred Shares for Shares or cash, as the case may be. Such
redemption of Series K Preferred Units shall occur substantially concurrently
with the redemption by the Trustee of such Series K Preferred Shares (such date
of redemption the "Redemption Date").

               (ii)   In the event that the Trustee redeems shares of Series K
Preferred Shares in exchange for Shares, an equivalent number of Series K
Preferred Units shall be converted into a number of Class A-2 Units equal to (x)
the number of Shares issued by the Trustee in redemption of such shares of
Series K Preferred Shares divided by (y) the Conversion Factor.

               (iii)  In the event that the Trustee redeems shares of Series K
Preferred Shares for cash (including payments of cash in lieu of fractional
Shares), the Trust shall redeem a like number of Series K Preferred Units in
exchange for the amount of cash that the Trustee is required to pay pursuant to
the terms of the Series K Preferred Shares in connection with such redemption.

                                       P-4

<PAGE>

               (iv) Upon any redemption of Series K Preferred Units pursuant to
this Section 4, the Trust shall pay any accrued and unpaid distributions, if
any, thereon to the Redemption Date, without interest. If the Redemption Date
falls after a Trust Record Date and prior to the corresponding Distribution
Date, then the Trustee, in its capacity as the holder of the Series K Preferred
Units being redeemed, shall be entitled to distributions payable on the
corresponding Distribution Date notwithstanding the redemption of such Series K
Preferred Units before such Distribution Date. Except as provided above, the
Trust shall make no payment or allowance for unpaid distributions, whether or
not in arrears, on Series K Preferred Units called for redemption.

               (v)  Any Class A-2 Unit issued upon redemption of the Series K
Preferred Units shall be validly issued, fully paid and non-assessable.

          (B)  In the event that the Trustee is required to redeem any shares of
Series K Preferred Shares pursuant to the terms thereof, the Trust shall redeem
an equivalent number of Series K Preferred Units for consideration equal to the
consideration payable by the Trustee upon redemption of such shares of Series K
Preferred Shares.

     (5)  Shares to be Retired. All Series K Preferred Units which are issued
          --------------------
and reacquired in any manner by the Trust shall be restored to the status of
authorized but unissued Units of the Trust, without designation as to class or
series.

     (6)  Conversion to Class A-2 Units.
          -----------------------------

          (A)  In the event that a holder of Series K Preferred Shares exercises
its right to convert such Series K Preferred Shares into Shares, then,
concurrently therewith, an equivalent number of Series K Preferred Units shall
be automatically converted into a number of Class A-2 Units equal to (x) the
number of Shares issued upon conversion of such Series K Preferred Shares
divided by (y) the Conversion Factor. Any such conversion will be effective at
the same time as the conversion of Series K Preferred Shares into Shares is
effective.

          (B)  The Trustee, in its capacity as the holder of Series K Preferred
Units that are converted pursuant to this Section 5 effective during the period
after a Trust Record Date and prior to the opening of business on the
corresponding Distribution Date, shall not be entitled to receive the
distribution payable on such Series K Preferred Units on such Distribution Date
notwithstanding such conversion thereof following the corresponding Trust Record
Date and prior to such Distribution Date.

     (7)  Ranking. Any class or series of Units shall be deemed to rank:
          -------

          (A)  senior to the Series K Preferred Units, in the payment of
distributions or in the distribution of assets upon any liquidation, dissolution
or winding up of the Trust, if the holders of such class or series of Units are
entitled to the receipt of distributions or of amounts distributable upon any
liquidation, dissolution or winding up of the Trust, as the case may be, in
preference or priority to the holders of Series K Preferred Units;

          (B)  on a parity with the Series K Preferred Units, in the payment of
distributions and in the distribution of assets upon any liquidation,
dissolution or winding up of

                                       P-5

<PAGE>

the Trust, whether or not the distribution rates, distribution payment dates or
redemption or liquidation prices per Unit are different from those of the Series
K Preferred Units, if the holders of such class or series of Units and the
holders of the Series K Preferred Units are entitled to the receipt of
distributions and of amounts distributable upon any liquidation, dissolution or
winding up of the Trust in proportion to their respective amounts of
distributions accrued and unpaid per Unit or liquidation preferences, without
preference or priority to each other ("Parity Units");

          (C) junior to the Series K Preferred Units, in the payment of
distributions or in the distribution of assets upon any liquidation, dissolution
or winding up of the Trust, if such class or series of Units is Junior Units;
and

          (D) junior to the Series K Preferred Units, in the payment of
distributions and in the distribution of assets upon any liquidation,
dissolution or winding up of the Trust, if such class or series of Units is
Fully Junior Units;

     (8)  Voting. Except as required by law, the Trustee, in its capacity as the
          ------
holder of the Series K Preferred Units, shall not be entitled to vote at any
meeting of the Unitholders or for any other purpose or otherwise to participate
in any action taken by the Trust or the Unitholders, or to receive notice of any
meeting of the Unitholders.

     (9)  Restriction on Ownership. The Series K Preferred Units shall be owned
          ------------------------
and held solely by the Trustee.

     (10) General. The rights of the Trustee, in its capacity as the holder of
          -------
the Series K Preferred Units, are in addition to and not in limitation on any
other rights or authority of the Trustee, in any other capacity, under the
Agreement. In addition, nothing contained in this Exhibit P shall be deemed to
                                                  ---------
limit or otherwise restrict any rights or authority of the Trustee under the
Agreement, other than in its capacity as the holder of the Series K Preferred
Units.

                   DESIGNATION OF THE PREFERENCES, CONVERSION
       AND OTHER RIGHTS, VOTING POWERS, RESTRICTIONS AND LIMITATIONS AS TO
                            SERIES L PREFERRED UNITS

      The Series L Preferred Units shall have the following designations,
preferences, rights, powers and duties:

     (1)   Certain Defined Terms. The following capitalized terms used in this
            ---------------------
Exhibit Q shall have the respective meanings set forth below:
---------

           "Distribution Date" means (i) for any Distribution Period with
            -----------------
respect to which the Trust pays a distribution on the Class A Units, the date on
which such distribution is paid, or (ii) for any Distribution Period with
respect to which the Trust does not pay a distribution on the Class A Units, the
date set by the Trustee for payment of dividends on the Series L Preferred
Shares, which date shall not be later than the forty-fifth calendar day after
the end of the applicable Distribution Period.

           "Distribution Period" means quarterly periods commencing on January
            -------------------
1, April 1, July 1 and October 1 of each year and ending on and including the
day preceding the first day of the next succeeding Distribution Period (other
than the Distribution Period during which any Series L Preferred Units shall be
redeemed pursuant to Section 4, which shall end on and include the date of such
redemption).

           "Fully Junior Units" shall mean the Common Units and any other class
            ------------------
or series of Units now or hereafter issued and outstanding over which the Series
L Preferred Units have preference or priority in both (i) the payment of
dividends and (ii) the distribution of assets on any liquidation, dissolution or
winding up of the Trust.

           "Issue Date" shall mean the first date on which the first Series L
            ----------
Preferred Units were issued.

           "Junior Units" shall mean the Common Units and any other class or
            ------------
series of Units now or hereafter issued and outstanding over which the Series L
Preferred Units have preference or priority in the payment of dividends or in
the distribution of assets on any liquidation, dissolution or winding up of the
Trust.

           "Parity Units" has the meaning ascribed thereto in Section 7(B).
            ------------

           "set apart for payment" shall be deemed to include, without any
            ---------------------
action other than the following, the recording by the Trust in its accounting
ledgers of any accounting or bookkeeping entry which indicates, pursuant to a
declaration of dividends or other distribution by the Trustee, the allocation of
funds to be so paid on any series or class of Units of the Trust; provided,
                                                                  --------
however, that if any funds for any class or series of Junior Units or any class
-------
or series of Units ranking on a parity with the Series L Preferred Units as to
the payment of distributions are placed in a separate account of the Trust or
delivered to a disbursing, paying or other similar agent, then "set apart for
payment" with respect to the Series L Preferred Units shall mean

                                       Q-1

<PAGE>

placing such funds in a separate account or delivering such funds to a
disbursing, paying or other similar agent.

           (2)   Distributions.
                 -------------
                 (A) The Trustee, in its capacity as the holder of the then
outstanding Series L Preferred Units, shall be entitled to receive, when, as and
if declared by the Trustee, out of funds legally available for the payment of
distributions, cumulative preferential distributions payable in cash in an
amount per Series L Preferred Unit equal to the greater of (a)(i) $3.2175 per
annum from the first day after the Issue Date up to and including November 5,
2001, and (ii) $3.315 per annum, or (b) the ordinary cash distributions
(determined on each Distribution Date) paid on the number of Class A-2 Units, or
portion thereof, into which a Series L Preferred Unit is convertible. The
distributions referred to in clause (b) of the preceding sentence shall equal
the number of Class A-2 Units, or portion thereof, into which a Series L
Preferred Unit is convertible, multiplied by the most recent quarterly
distribution on a Class A-2 Unit on or before the applicable Distribution Date.
If the Trust pays an ordinary cash distribution on the Class A-2 Units with
respect to a Distribution Period after the date on which the Distribution Date
is declared pursuant to clause (ii) of the definition of Distribution Date and
the distribution calculated with respect to clause (b) of the first sentence of
this Section 2(A) is greater than the distribution previously declared on the
Series L Preferred Units with respect to such Distribution Period, the Trust
shall pay an additional distribution in respect of the Series L Preferred Units
on the date on which the distribution on the Class A-2 Units is paid, in an
amount equal to the difference between (y) the distribution calculated pursuant
to clause (b) of the first sentence of this Section 2(A) and (z) the amount of
distributions previously declared on the Series L Preferred Units with respect
to such Distribution Period. Distributions shall begin to accrue and shall be
fully cumulative from October 1, 2001, whether or not in any Distribution Period
or Periods there shall be funds of the Trust legally available for the payment
of such distributions, and shall be payable quarterly, when, as and if declared
by the Trustee, in arrears on Distribution Dates. Accrued and unpaid
distributions for any past Distribution Periods may be declared and paid at any
time and for such interim periods, without reference to any regular Distribution
Date, to the Trustee, in its capacity as the holder of the Series L Preferred
Units, on such date as may be fixed by the Trustee for payment of the
corresponding dividend on the Series L Preferred Shares. Any distribution made
on the Series L Preferred Units shall first be credited against the earliest
accrued but unpaid distribution due with respect to Series L Preferred Units
which remains payable.

                  (B) The amount of distributions referred to in clause (a) of
the first sentence of Section 2(A) shall be equal to the annual distribution
rate payable for each full Distribution Period for the Series L Preferred Units
shall be computed by dividing the applicable rate by four. The amount of
distributions payable for any period shorter than a full Distribution Period, on
the Series L Preferred Units shall be computed on the basis of a 360-day year of
twelve 30-day months. No interest, or sum of money in lieu of interest, shall be
payable in respect of any distribution payment or payments on the Series L
Preferred Units that may be in arrears.

                  (C) So long as any Series L Preferred Units are outstanding,
no distributions, except as described in the immediately following sentence,
shall be declared or paid or set apart for payment on any class or series of
Parity Units for any period unless full cumulative

                                       Q-2

<PAGE>

distributions have been or contemporaneously are declared and paid or declared
and a sum sufficient for the payment thereof set apart for such payment on the
Series L Preferred Units for all Distribution Periods terminating on or prior to
the distribution payment date for such class or series of Parity Units. When
distributions are not paid in full or a sum sufficient for such payment is not
set apart, as aforesaid, all distributions declared upon Series L Preferred
Units and all distributions declared upon any other class or series of Parity
Units shall be declared ratably in proportion to the respective amounts of
distributions accumulated and unpaid on the Series L Preferred Units and
accumulated and unpaid on such Parity Units.

                  (D) So long as any Series L Preferred Units are outstanding,
no distributions (other than distributions paid solely in Fully Junior Units or
options, warrants or rights to subscribe for or purchase Fully Junior Units)
shall be declared or paid or set apart for payment or other distribution shall
be declared or made or set apart for payment upon Junior Units, nor shall any
Junior Units be redeemed, purchased or otherwise acquired (other than a
redemption, purchase or other acquisition of Common Units made for purposes of
an employee incentive or benefit plan of the Trustee, the Trust or any
subsidiary) for any consideration (or any moneys be paid to or made available
for a sinking fund for the redemption of any such Junior Units) by the Trust,
directly or indirectly (except by conversion into or exchange for Fully Junior
Units), unless in each case (i) the full cumulative distributions on all
outstanding Series L Preferred Units and any other Parity Units of the Trust
shall have been paid or declared and set apart for payment for all past
Distribution Periods with respect to the Series L Preferred Units and all past
distribution periods with respect to such Parity Units and (ii) sufficient funds
shall have been paid or set apart for the payment of the distribution for the
current Distribution Period with respect to the Series L Preferred Units and the
current distribution period with respect to such Parity Units.

                  (E) No distributions on the Series L Preferred Units shall be
declared by the Trustee or paid or set apart for payment by the Trust at such
time as the terms and provisions of any agreement of the Trustee or the Trust,
including any agreement relating to indebtedness of either of them, 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.

         (3)      Liquidation Preference.
                  ----------------------
                  (A) In the event of any liquidation, dissolution or winding up
of the Trust, whether voluntary or involuntary, before any payment or
distribution of the assets of the Trust shall be made to or set apart for the
holders of Junior Units, the Trustee, in its capacity as holder of the Series L
Preferred Units, shall be entitled to receive Thirty-Nine Dollars ($39.00) (the
"Series L Liquidation Preference") per Series L Preferred Unit plus an amount
equal to all distributions (whether or not earned or declared) accrued and
unpaid thereon to the date of final distribution to the Trustee, in its capacity
as such holder; but the Trustee, in its capacity as the holder of Series L
Preferred Units, shall not be entitled to any further payment; provided that the
distribution payable with respect to the Distribution Period containing the date
of final distribution shall be equal to the greater of (i) the distribution
provided in clause (a) of the first sentence of Section 2(A) or (ii) the
distribution determined pursuant to clause (b) of the first sentence of Section
2(A) for the preceding Distribution Period. If, upon any liquidation,

                                       Q-3

<PAGE>

dissolution or winding up of the Trust, the assets of the Trust, or proceeds
thereof, distributable to the Trustee, in its capacity as the holder of Series L
Preferred Units, shall be insufficient to pay in full the preferential amount
aforesaid and liquidating payments on any other class or series of Parity Units,
then such assets, or the proceeds thereof, shall be distributed among the
Trustee, in its capacity as the holder of such Series L Preferred Units, and the
holders of such other Parity Units ratably in accordance with the respective
amounts that would be payable on such Series L Preferred Units and such other
Parity Units if all amounts payable thereon were paid in full. For the purposes
of this Section 3, (x) a consolidation or merger of the Trust with one or more
partnerships, limited liability companies, corporations, real estate investment
trusts or other entities, (y) a sale, lease or conveyance of all or
substantially all of the Trust's property or business or (z) a share exchange
shall not be deemed to be a liquidation, dissolution or winding up, voluntary or
involuntary, of the Trust.

                  (B) Subject to the rights of the holders of Units of any
series or class ranking on a parity with or prior to the Series L Preferred
Units upon any liquidation, dissolution or winding up of the Trust, after
payment shall have been made in full to the Trustee, in its capacity as the
holder of the Series L Preferred Units, as provided in this Section 3, any other
series or class or classes of Junior Units shall, subject to any respective
terms and provisions (if any) applying thereto, be entitled to receive any and
all assets remaining to be paid or distributed, and the Trustee, in its capacity
as the holder of the Series L Preferred Units, shall not be entitled to share
therein.

         (4)      Redemption Right.
                  ----------------
                  (A) Except as provided in Section 4(B), the Series L Preferred
Units shall not be redeemable by the Trust prior to November 5, 2005. On and
after November 5, 2005, the Trustee may cause the Trust, at its option, to
redeem the Series L Preferred Units, in whole at any time or from time to time
in part, from funds legally available therefor, (x) for Class A-2 Units, subject
to the conditions set forth in paragraph (i) below, or (y) for cash in an amount
per Series L Preferred Unit equal to the Series L Liquidation Preference plus
accrued and unpaid distributions (the "Redemption Price"), in each case subject
to the conditions set forth below.

                      (i)   The Series L Preferred Units shall be redeemed only
if the Trustee shall concurrently therewith redeem an equivalent number of
shares of Series L Preferred Shares for Shares or cash, as the case may be. Such
redemption of Series L Preferred Units shall occur substantially concurrently
with the redemption by the Trustee of such Series L Preferred Shares (such date
of redemption the "Redemption Date").

                      (ii)  In the event that the Trustee redeems shares of
Series L Preferred Shares in exchange for Shares, an equivalent number of Series
L Preferred Units shall be converted into a number of Class A-2 Units equal to
(x) the number of Shares issued by the Trustee in redemption of such shares of
Series L Preferred Shares divided by (y) the Conversion Factor.

                      (iii) In the event that the Trustee redeems shares of
Series L Preferred Shares for cash (including payments of cash in lieu of
fractional Shares), the Trust shall redeem a like number of Series L Preferred
Units in exchange for the amount of cash that the Trustee is

                                       Q-4

<PAGE>

required to pay pursuant to the terms of the Series L Preferred Shares in
connection with such redemption.

                 (iv) Upon any redemption of Series L Preferred Units pursuant
to this Section 4, the Trust shall pay any accrued and unpaid distributions, if
any, thereon to the Redemption Date, without interest. If the Redemption Date
falls after a Trust Record Date and prior to the corresponding Distribution
Date, then the Trustee, in its capacity as the holder of the Series L Preferred
Units being redeemed, shall be entitled to distributions payable on the
corresponding Distribution Date notwithstanding the redemption of such Series L
Preferred Units before such Distribution Date. Except as provided above, the
Trust shall make no payment or allowance for unpaid distributions, whether or
not in arrears, on Series L Preferred Units called for redemption.

                 (v)  Any Class A-2 Unit issued upon redemption of the Series L
Preferred Units shall be validly issued, fully paid and non-assessable.

             (B) In the event that the Trustee is required to redeem any shares
of Series L Preferred Shares pursuant to the terms thereof, the Trust shall
redeem an equivalent number of Series L Preferred Units for consideration equal
