                FIRST AMENDMENT TO AGREEMENT AND PLAN OF MERGER

     THIS FIRST AMENDMENT TO AGREEMENT AND PLAN OF MERGER (this "First
Amendment") is entered into as of May 11, 2000 by and among EQUITY OFFICE
PROPERTIES TRUST, a Maryland real estate investment trust ("EOP"), EOP OPERATING
LIMITED PARTNERSHIP, a Delaware limited partnership ("EOP Partnership"),
CORNERSTONE PROPERTIES INC., a Nevada corporation ("Cornerstone"), and
CORNERSTONE PROPERTIES LIMITED PARTNERSHIP, a Delaware limited partnership
("Cornerstone Partnership"), for the purpose of amending the Agreement and Plan
of Merger, dated as of February 11, 2000, entered into by and among EOP, EOP
Partnership, Cornerstone, and Cornerstone Partnership (the "Merger Agreement").
All capitalized terms herein and not otherwise defined shall have the meanings
ascribed to them in the Merger Agreement.

     WHEREAS, the parties hereto desire to amend certain provisions of the
Merger Agreement to clarify certain matters as provided herein;

     NOW, THEREFORE, in consideration of the mutual covenants set forth herein,
and other good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, the parties hereto agree as follows:

SECTION 1. SELECTION OF UNSATISFIED CONDITIONAL REDEMPTIONS BY LOT;
           CLARIFICATION OF PRORATION PROVISIONS.

     (a) Section 1.1(a)(v) of the Merger Agreement is amended by redesignating
such section as Section 1.1(a)(v)(A).

     (b) Section 1.1(a)(v) of the Merger Agreement is amended further by
changing the phrase "the procedures set forth in Sections 1.11 and 1.12" to read
"the procedures set forth in Sections 1.1(a)(v)(B), 1.11 and 1.12".

     (c) Section 1.1(a)(v) of the Merger Agreement is amended further by adding
the following new subparagraph (B):

          (B) In the event that Section 1.12(b)(ii)(B) is applicable and Excess
     Cash (as defined in Section 1.12(b)(ii)(B)) is allocated to the Conditional
     Cash Elections (as defined in Section 1.12(b)(i)(B)), each conditional
     Exercise made pursuant to Section 1.1(a)(v)(A) that, pursuant to Section
     1.1(a)(v)(A), would not be not effective (before giving effect to the
     procedures set forth in this subparagraph (B)) shall, together with all
     other such conditional Exercises, be subject to being chosen by lot from
     among other such conditional Exercises to receive a portion of the Excess
     Cash. Any conditional Exercise that is chosen by lot shall be made
     effective if sufficient remaining Excess Cash is available (after taking
     into account all prior conditional Exercises chosen by lot) to pay to the
     Redeeming Partner who submitted such conditional Exercise cash for each
     share of Cornerstone Common Stock that must be converted into solely cash
     in order for such conditional Exercise to be effective. Conditional
     Exercises described in the first sentence of this subparagraph (B) shall be
     subject to being chosen by lot until the amount of remaining Excess Cash
     available is less than the amount of cash that would be required to allow
     any of the remaining conditional Exercises to become effective pursuant to
     the requirements of Section 1.1(a)(v)(A).

     (d) Section 1.12(a) of the Merger Agreement is amended by adding the
following sentence at the end thereof:

          Except as otherwise expressly provided pursuant to this Section 1.12,
     each share of Cornerstone Common Stock for which a Cash Election is
     received shall be converted into the right to receive $18.00 per share in
     cash, without interest, and each share of Cornerstone Common Stock for
     which a Share Election is received shall be converted into EOP Common
     Shares in accordance with the Common Stock Exchange Ratio.
<PAGE>   2

     (e) Section 1.12(b) of the Merger Agreement is amended by deleting the
indented language and substituting therefor the following subparagraphs (i) and
(ii):

          (i) in the event that Non-conditional Cash Elections (defined to mean
     all Cash Elections received other than Conditional Cash Elections as
     defined in Section 1.12(b)(i)(B), below) are received for a number of
     shares of Cornerstone Common Stock that is greater than 58,551,525 shares
     of Cornerstone Common Stock, then:

             (A) each share of Cornerstone Common Stock covered by a
        Non-conditional Cash Election shall be converted into the right to
        receive (1) an amount in cash, without interest, equal to the product of
        (x) $18.00 and (y) a fraction (the "Cash Fraction") the numerator of
        which shall be 58,551,525 and the denominator of which shall be the
        aggregate number of shares of Cornerstone Common Stock covered by all
        Non-conditional Cash Elections, and (2) a number of EOP Common Shares
        equal to the product of (x) the Common Stock Exchange Ratio and (y) a
        fraction equal to one minus the Cash Fraction; and

             (B) each Conditional Cash Election (defined to mean any Cash
        Election received with respect to Electing Cornerstone OP Units with
        respect to which a conditional Exercise is made pursuant to Section
        1.1(a)(v)(A)) shall be of no force and effect; and

          (ii) in the event that Non-conditional Cash Elections are received for
     a number of shares of Cornerstone Common Stock that is equal to or less
     than 58,551,525 shares of Cornerstone Common Stock, then:

             (A) each share of Cornerstone Common Stock covered by a
        Non-conditional Cash Election shall be converted into the right to
        receive an amount in cash, without interest, equal to $18.00; and

             (B) an amount of cash equal to the product of (x) $18.00 and (y)
        the excess, if any, of 58,551,525 over the number of shares of
        Cornerstone Common Stock for which Non-conditional Cash Elections are
        received (referred to as "Excess Cash") shall be allocated to the
        Conditional Cash Elections as a group, to be applied as provided for in
        Section 1.1(a)(v)(B).

SECTION 2. NOTICE PERIOD FOR FINAL DIVIDEND.

     Section 1.15(d)(i) of the Merger Agreement is amended by deleting the
number "10" in the second sentence of Section 1.15(d)(i) and substituting the
number "20" therefor.

SECTION 3. FRACTIONAL EOP OP UNITS.

     (a) Section 1.15(g) of the Merger Agreement is amended by adding "; No
Fractional EOP OP Units" after the word "Shares" in the caption.

     (b) Section 1.15(g) of the Merger Agreement is amended by adding the
following new paragraph (iii):

          (iii) No fractional EOP Partnership Units shall be issued pursuant to
     this Agreement. In lieu of the issuance of any fractional EOP Partnership
     Units pursuant to this Agreement, each holder of Cornerstone OP Units who
     would receive, based on the exchange ratio specified in Section 1.10(a)(i),
     a number of EOP OP Units that is not a whole number shall receive instead a
     number of EOP OP Units that is equal to the whole number that is nearest to
     the fractional number of EOP OP Units that otherwise would be paid to such
     holder of Cornerstone OP Units based on the exchange ratio specified in
     Section 1.10(a)(i).

     (c) Section 1.15(i) of the Merger Agreement is amended by adding "," and
deleting the word "and" after the word "certificates" in the second clause and
adding "and fractional EOP Common Shares" after the word "procedure" in such
second clause.

SECTION 4. AMENDMENT OF SECTION 5.10 TO PROVIDE FOR A SPECIAL DIVIDEND BY
           CORNERSTONE OF $0.03 PER SHARE OF COMMON STOCK.

     Section 5.10 is amended to add at the end thereof the following new
language:

          Notwithstanding any of the foregoing or any provision of Section
     1.15(d), in the event that EOP and Cornerstone do not declare their regular
     dividend distributions for the second quarter of 2000 prior to the
     Effective Time of the Merger, (i) Cornerstone shall declare and pay to the
     holders of Cornerstone Common Stock a special dividend in the amount of
     $0.03 per share, the record date for which shall be not later than the
     close of business on the last day prior the Effective Time of the Merger
     (the "Special Dividend"), and Cornerstone shall cause to be withheld from
     the Special Dividend payable to Persons who are not "United States persons"
     (as defined in Section 7701(a)(30) of the Code) $0.02 per share or such
     higher amount as shall be sufficient so that Cornerstone shall be
     considered to have complied fully with the withholding requirements
     applicable to it under Treasury Regulations Section 1.1445-8 and Section
     1445 of the Code with respect to all distributions paid by it during
     calendar year 2000 (and to the extent such treatment is necessary, or
     Cornerstone deems it to be desirable, to permit or facilitate
     such withholding, Cornerstone shall treat the Special Dividend as a
     "capital gain dividend" for purposes of Treasury Regulations Section
     1.1445-8 and Section 1445 of the Code), and (ii) Cornerstone Partnership
     shall make a distribution to the holders of the Cornerstone OP Units at a
     time and in an amount sufficient to permit Cornerstone to pay the Special
     Dividend as contemplated hereby. The Special Dividend shall be paid on or
     prior to the last business day prior to the Closing Date. EOP shall not
     make any distribution to the holders of the EOP Common Shares to correspond
     to the Special Dividend to be paid to the holders of Cornerstone Common
     Stock.

SECTION 5. INDEX OF DEFINED TERMS.

     The Index of Defined Terms contained in the Merger Agreement is amended by
adding the following new entries:

</TABLE>

SECTION 6. CONSTRUCTION OF MERGER AGREEMENT.

and effect as if the provisions of the Merger Agreement and this First Amendment
were contained in one document. Except as expressly amended by this First
Amendment, the Merger Agreement shall remain in full force and effect in
accordance with its terms.

SECTION 7. COUNTERPARTS.

the parties hereto in separate counterparts, each of which when so executed
shall be deemed to be an original and all of which taken together shall

                         EQUITY OFFICE PROPERTIES TRUST

         Equity Office Properties Trust, a Maryland real estate investment trust
(hereinafter called the "Trust"), hereby certifies to the State Department of

deleting existing Section 8.2 in its entirety and adding a new Section 8.2 to
read as follows:

         " Section 8.2 Voting Rights. Subject to the provisions of any class or
series of Shares then outstanding, the shareholders shall be entitled to vote
only on the following matters: (a) election of Trustees as provided in Section
5.2 and the removal of Trustees as provided in Section 5.3; (b) amendment of the
Declaration of Trust as provided in Article X; (c) termination of the Trust as
provided in Section 11.2; (d) a Business Combination (as defined in Section
8.4), if a shareholder vote is required under Section 8.4; (e) such other

by deleting existing Section 8.4 in its entirety and adding a new Section 8.4 to
read as follows:

Combination"). Subject to the terms of any class or series of Shares at the time
outstanding, if a shareholder vote is required under Title 8 to effect any such
merger, then such merger must be approved by shareholders by the affirmative
vote of not less than a majority of all votes entitled to be cast on the matter.
Subject to the terms of any class or series of Shares at the time outstanding,
any Business Combination other than a merger must be approved by shareholders by
the affirmative vote of not less than a majority of all votes entitled to be
cast on the matter. For purposes of this Section 8.4, the term "transfer assets"
means to sell, lease, exchange, or otherwise transfer all or substantially all
of the assets of the Trust, but shall not include (a) any sale, lease, exchange,
or other transfer of all or substantially all of the assets of the Trust in the
ordinary course of business actually conducted by it or as a distribution to its
shareholders, (b) the mortgage, pledge, or creation of any other security
interest in any or all of the assets of the Trust, whether or not in the
ordinary course of business or (c) the sale, lease, exchange, or other transfer
of all or substantially all of the assets of the Trust to one or more entities
if at least a majority of the equity interests of the entity or entities are
owned, directly or indirectly, by the Trust. Notwithstanding any other
provisions of this Declaration of

Trust, the affirmative vote of shareholders holding at least a majority of all
votes entitled to be cast on the matter shall be required to amend this Section
8.4."

         THIRD: The amendments to the Declaration of Trust of the Trust as set
forth above have been advised by the Board of Trustees and approved by the
shareholders of the Trust as required by law and the Declaration of Trust of the

                                     BYLAWS

1.    AMENDMENT OF ARTICLE II, SECTION 9

         Article II, Section 9 of the Equity Office Bylaws is amended to read in
its entirety as set forth below:

         "Section 9. PROXIES. A shareholder may cast the votes entitled to be
cast by the shares owned of record by him in person or by proxy as provided in
this section. No proxy shall be valid after eleven months from the date of its
execution, unless otherwise provided in the proxy. Unless otherwise agreed in
writing, the holder of record of shares which actually belong to another shall
issue a proxy to vote the shares to the actual owner on the owner's demand. A
shareholder may authorize another person to act as proxy for the shareholder. A
shareholder may sign a writing authorizing another person to act as proxy.
Signing may be accomplished by the shareholder or the shareholder's authorized
agent signing the writing or causing the shareholder's signature to be affixed
to the writing by any reasonable means, including facsimile signature. A
shareholder may authorize another person to act as proxy by transmitting, or
authorizing the transmission of, an authorization for the person to act as proxy
to the person authorized to act as proxy or any other person authorized to
receive the proxy authorization on behalf of the person authorized to act as the
proxy, including a proxy solicitation firm or proxy support service
organization. The authorization may be transmitted by a telegram, cablegram,
datagram, electronic mail, or any other electronic or telephonic means. A copy,
facsimile telecommunication, or other reliable reproduction of the writing or
transmission authorized under this subsection may be substituted for the
original writing or transmission for any purpose for which the original writing
or transmission could be used."

2.  AMENDMENTS TO ARTICLE IV, SECTIONS 8.1 THROUGH 8.5

         Article IV, Sections 8.1 through 8.5 of the Bylaws are renumbered as
Sections 8(a) through 8(e) and all internal cross-references to the former
Sections 8.1 through 8.5 are changed accordingly.

         The phrase "or a Trust or estate" in the definition of "Related Person"
contained in Article IV, Section 8(e) is deleted and replaced with the phrase
"or a trust or estate."

3.    AMENDMENTS TO ARTICLE VII, SECTIONS 1, 2 AND 5

         Article VII, Sections 1 and 2 are amended in their entirety to read as
set forth below:

         "Section 1. CERTIFICATES; UNCERTIFICATED SHARES. Unless the Board of
Trustees of the Trust authorizes the issue of some or all of the shares of any
or all of its classes or series without certificates, each shareholder shall be
entitled to a certificate or certificates which shall represent and certify the
number of shares of each class of beneficial interest held by him in the Trust.
Each certificate shall be signed by the chief executive officer, 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 or series of shares, each class or series 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 of the Trust 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. In lieu of such statement or
summary, the Trust may set forth upon the face or back of the certificate a
statement that the Trust will furnish to any shareholder, upon request and
without charge, a full statement of such information. At the time of issue or
transfer of shares without certificates, the Trust shall send the shareholder a
written statement of the information required on certificates by Section 8-203
of Title 8 of the Corporations and Associations Article of the Annotated Code of
Maryland.

         Section 2. TRANSFERS. Certificates shall be treated as negotiable and
title thereto and to the shares they represent shall be transferred by delivery
thereof duly endorsed or with proper evidence of transfer to the same extent as
those of a Maryland stock corporation. Upon surrender to the Trust or the
transfer agent of the Trust of a share certificate or uncertificated security
duly endorsed or accompanied by proper evidence of succession, assignment or
authority to transfer, the Trust shall issue a new certificate or uncertificated
security to the person entitled thereto, cancel the old certificate and record
the transaction upon its books.

         The Trust shall be entitled to treat the holder of record of any share
or shares 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 shares 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.

         Notwithstanding the foregoing, transfers of shares of beneficial
interest of the Trust will be subject in all respects to the Declaration of
Trust and all of the terms and conditions contained therein."

         The title of Article VII, Section 5 is deleted and replaced with "Share
Ledger."

                    BYLAWS (as amended through May 4, 2000)

                                   ARTICLE I

Properties Trust (the "Trust") shall be located at such place or places as the
Trustees may designate.

         Section 2.  ADDITIONAL OFFICES.  The Trust may have additional offices
at such places as the Trustees may from time to time determine or the business
of the Trust may require.



                                   ARTICLE II

                            MEETINGS OF SHAREHOLDERS

         Section 1.  PLACE.  All meetings of shareholders 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 MEETING.  An annual meeting of the shareholders for
the election of Trustees and the transaction of any business within the powers
of the Trust shall be held during the month of May of each year, after the
delivery of the annual report referred to in Section 12 of this Article II, at
a convenient location and on proper notice, on a date and at the time set by
the Trustees, beginning with the year 1998. 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 or the
president or one-third of the Trustees may call special meetings of the
shareholders.  Special meetings of shareholders shall also be called by the
secretary upon the written request of the holders of shares entitled to cast
not less than a majority of all the votes entitled to be cast at such meeting.
Such request shall state the purpose of such meeting and the matters proposed
to be acted on at such meeting.  Within ten (10) days of the receipt of such a
request, the secretary shall inform such shareholders of the reasonably
estimated cost of preparing and mailing notice of the meeting (including all
proxy materials that may be required in connection therewith) and, upon payment
by such shareholders to the Trust of such costs, the secretary shall, within
thirty (30) days of such payment, or such longer period as may be necessitated
by compliance with any applicable statutory or regulatory requirements, give
notice to each shareholder entitled to notice of the meeting.

         Unless requested by shareholders entitled to cast a majority of all
the votes entitled to be cast at such meeting, a special meeting need not be
called to consider any matter
<PAGE>   2
which is substantially the same as a matter voted on at any meeting of the
shareholders held during the preceding twelve months.

         Section 4.  NOTICE.  Not less than ten nor more than 90 days before
each meeting of shareholders, the secretary shall give to each shareholder
entitled to vote at such meeting and to each shareholder not entitled to vote
who is entitled to notice of the meeting written or printed notice stating the
time and place of the meeting and, in the case of a special meeting or as
otherwise may be required by any statute, the purpose for which the meeting is
called, either by mail or by presenting it to such shareholder personally or by
leaving it at his residence or usual place of business.  If mailed, such notice
shall be deemed to be given when deposited in the United States mail addressed
to the shareholder at his 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.  ORGANIZATION.  At every meeting of the shareholders, the
Chairman of the Board, if there be one, shall conduct the meeting or, in the
case of vacancy in office or absence of the Chairman of the Board, one of the
following officers present shall conduct the meeting in the order stated: the
Vice Chairman of the Board, if there be one, the President, 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 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.

         Section 7.  QUORUM.  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 at such meeting shall constitute a quorum; but this section
shall not affect any requirement under any statute or the declaration of trust
("Declaration of Trust") for the vote necessary for the adoption of any
measure.  If, however, such quorum shall not be 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 the meeting from time to
time to a date not more than 120 days after the original record date without
notice other than announcement at the meeting.  At 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.

         Section 8.  VOTING.  A plurality of all the votes cast at a meeting of
shareholders duly called and at which a quorum is present shall be sufficient
to elect a Trustee.  Each share may be voted for as many individuals as there
are Trustees to be elected and for whose election the share is entitled to be
voted.  A majority of the votes cast at a meeting of shareholders duly called
and at which a quorum is present shall be sufficient to approve any other
matter which may properly come before the meeting, unless more than a majority
of the votes cast is required herein or by statute or by the Declaration of
Trust.





                                       2
<PAGE>   3
Unless otherwise provided in the Declaration of Trust, each outstanding share,
regardless of class, shall be entitled to one vote on each matter submitted to
a vote at a meeting of shareholders.

         Section 9.  PROXIES.  A shareholder may cast the votes entitled to be
cast by the shares owned of record by him either in person or by proxy executed
in writing by the shareholder or by his duly authorized attorney in fact.  Such
proxy shall be filed with the Secretary of the Trust before or at the time of
the meeting.  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.  Shares of the Trust
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 board of such corporation or other entity or agreement of the
partners of the partnership presents a certified copy of such bylaw, resolution
or agreement, in which case such person may vote such shares.  Any trustee or
other fiduciary may vote shares registered in his name as such fiduciary,
either in person or by proxy.

         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.

         The Trustees 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 and 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
Trustees consider 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.

         Notwithstanding any other provision contained herein or in the
Declaration of Trust or these Bylaws, Title 3, Subtitle 7 of the Corporations
and Associations Article of the Annotated Code of Maryland (or any successor
statute) shall not apply to any acquisition by any person of shares of
beneficial interest 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,
apply to any prior or subsequent control share acquisition.

<PAGE>   4
         Section 11.  INSPECTORS.  At any meeting of shareholders, the chairman
of the meeting may appoint one or more persons as inspectors for such meeting.
Such inspectors shall ascertain and report the number of shares represented at
the meeting based upon 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.  REPORTS TO SHAREHOLDERS.  The Trustees shall submit to
the shareholders at or before the annual meeting of shareholders a report of
the business and operations of the Trust during such fiscal year, containing a
balance sheet and a statement of income and surplus of the Trust, accompanied
by the certification of an independent certified public accountant, and such
further information as the Trustees may determine is required pursuant to any
law or regulation to which the Trust is subject.  Within the earlier of 20 days
after the annual meeting of shareholders or 120 days after the end of the
fiscal year of the Trust, the Trustees shall place the annual report on file at
the principal office of the Trust and with any governmental agencies as may be
required by law and as the Trustees may deem appropriate.

         Section 13.  NOMINATIONS AND PROPOSALS BY SHAREHOLDERS.

                 (a)      Annual Meetings of Shareholders.  (1)  Nominations of
persons for election to the Board of Trustees 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 meeting, (ii) by or at the
direction of the Trustees or (iii) 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 13 (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 13(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 13, the shareholder must have given
timely notice thereof in writing to the Secretary of the Trust and such 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 later than the close of business
on the 60th day nor earlier than the close of business on the 90th day prior to
the first anniversary of the preceding year's annual meeting; provided,
however, that in the event that the date of the annual meeting is advanced by
more than 30 days or delayed by more than 60 days from such anniversary date or
if the Trust has not previously held an annual meeting, notice by the
shareholder to be timely must be so delivered not earlier than the close of
business on the 90th day prior to such annual meeting and not later than the
close of business on the later of the 60th day prior to such annual meeting or
the tenth day following the day on which public announcement of the date of
such meeting is first made





                                       4
<PAGE>   5
by the Trust.  In no event shall the public announcement of a postponement or
adjournment of an annual meeting to a later date or time commence a new time
period for the giving of a shareholder's notice as described above.  Such
shareholder's notice shall set forth as to each person whom the shareholder
proposes to nominate for election or reelection as a Trustee all information
relating to such person that is required to be disclosed in solicitations of
proxies for election of Trustees in an election contest, 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 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 that 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 and (y) the number of each class of shares of the Trust
which are owned beneficially and of record by such shareholder and such
beneficial owner.

                          (3)     Notwithstanding anything in the second
sentence of paragraph (a) (2) of this Section 13 to the contrary, in the event
that the number of Trustees to be elected to the Board of Trustees 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 of Trustees at least 70
days prior to the first anniversary of the preceding year's annual meeting, a
shareholder's notice required by this Section 13(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 of Trustees may be made at a
special meeting of shareholders at which Trustees are to be elected (i)
pursuant to the Trusts notice of meeting (ii) by or at the direction of the
Board of Trustees or (iii) provided that the Board of Trustees has determined
that Trustees shall 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 13(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 13 (b).  In the event the Trust calls a special
meeting of shareholders for the purpose of electing one or more Trustees to the
Board of Trustees, 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 13 shall be delivered to the
Secretary at the principal executive offices of the Trust not earlier than the
close of business on the 90th day prior to such special meeting and not later
than the close of business on the later of the 60th day prior to such special
meeting or the tenth day following the day on which public announcement is
first made of the date of

<PAGE>   6
the special meeting and of the nominees proposed by the Trustees to be elected
at such meeting.  In no event shall the public announcement of a postponement
or adjournment of a special meeting to a later date or time commence a new time
period for the giving of a shareholder's notice as described above.

                 (c)  General.  (1) Only such persons who are nominated in
accordance with the procedures set forth in this Section 13 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 13.  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, as the case may
be, in accordance with the procedures set forth in this Section 13 and, if any
proposed nomination or business is not in compliance with this Section 13, to
declare that such nomination or proposal shall be disregarded.

                      (2)     For purposes of this Section 13, "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 13, a shareholder shall also comply with all applicable requirements of
state law and of the Exchange Act and the rules and regulations thereunder with
respect to the matters set forth in this Section 13.  Nothing in this Section
13 shall be deemed to affect any rights of shareholders to request inclusion of
proposals in, nor any of the rights of the Trust to omit a proposal from, the
Trust's proxy statement pursuant to Rule 14a-8 under the Exchange Act.

         Section 14.  INFORMAL ACTION BY SHAREHOLDERS.  Notwithstanding the
provisions of Section 13 of this Article II, any action required or permitted
to be taken at a meeting of shareholders may be taken without a meeting if a
consent in writing, setting forth such action, is signed by shareholders
entitled to cast a sufficient number of votes to approve the matter, as
required by statute, the Declaration of Trust of the Trust or these Bylaws, and
such consent is filed with the minutes of proceedings of the shareholders.

         Section 15.  VOTING BY BALLOT.  Voting on any question or in any
election may be viva voce unless the presiding officer shall order or any
shareholder shall demand that voting be by ballot.



                                  ARTICLE III

                                    TRUSTEES

         Section 1.   GENERAL POWERS; QUALIFICATIONS; TRUSTEES HOLDING OVER.
The business and affairs of the Trust shall be managed under the direction of
its Board of Trustees.  A Trustee shall be an individual at least 21 years of
age who is not

under legal disability.  In case of failure to elect Trustees at an annual
meeting of the shareholders, the Trustees holding over shall continue to direct
the management of the business and affairs of the Trust until their successors
are elected and qualify.

         Section 2.  NUMBER.  At any regular meeting or at any special meeting
called for that purpose, a majority of the entire Board of Trustees may
establish, increase or decrease the number of Trustees, subject to any
limitations on the number of Trustees set forth in the Declaration of Trust.
Except during the period when a vacancy exists, at least two-thirds of the
Trustees shall be persons who are not executive officers of the Trust or
persons affiliated with Samuel Zell or his affiliates ("Independent Trustees").
For purposes of this Section, the terms "executive officers" and "affiliated"
shall have the definitions set forth in Rule 405 under the Securities Act of
1933, as amended.

         Section 3.  ANNUAL AND REGULAR MEETINGS.  An annual meeting of the
Trustees 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
Trustees may provide, by resolution, the time and place, either within or
without the State of Maryland, for the holding of regular meetings of the
Trustees without other notice than such resolution.

         Section 4.  SPECIAL MEETINGS.  Special meetings of the Trustees may be
called by or at the request of the chairman of the board or the president or by
a majority of the Trustees then in office.  The person or persons authorized to
call special meetings of the Trustees may fix any place, either within or
without the State of Maryland, as the place for holding any special meeting of
the Trustees called by them.

         Section 5.  NOTICE.  Notice of any special meeting shall be given by
written notice delivered personally, telegraphed, facsimile-transmitted or
mailed to each Trustee at his business or residence address.  Personally
delivered or telegraphed notices 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.
Telephone or facsimile-transmission notice shall be given at least 24 hours
prior to the meeting.  If mailed, such notice shall be deemed to be given when
deposited in the United States mail properly addressed, with postage thereon
prepaid.  If given by telegram, such notice shall be deemed to be given when
the telegram is delivered to the telegraph company. Telephone notice shall be
deemed 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
given upon completion of the transmission of the message to the number given to
the Trust by the Trustee and receipt of a completed answer-back indicating
receipt.  Neither the business to be transacted at, nor the purpose of, any
annual, regular or special meeting of the Trustees need be stated in the
notice, unless specifically required by statute or these Bylaws.

         Section 6.  QUORUM.  A majority of the Trustees shall constitute a
quorum for transaction of business at any meeting of the Trustees, provided
that, if less than a majority of such Trustees are present at said meeting, a
majority of the Trustees present may adjourn the meeting from time to time
without further notice, and provided further 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.





                                       7
<PAGE>   8
                 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.  The action of the majority of the Trustees
present at a meeting at which a quorum is present shall be the action of the
Trustees, unless the concurrence of a greater proportion is required for such
action by applicable statute.

         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 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.  INFORMAL ACTION BY TRUSTEES.  Any action required or
permitted to be taken at any meeting of the Trustees may be taken without a
meeting, if a consent in writing to such action is signed by each Trustee and
such written consent is filed with the minutes of proceedings of the Trustees.

         Section 10.  VACANCIES.  If for any reason any or all of the Trustees
cease to be Trustees, such event shall not terminate the Trust or affect these
Bylaws or the powers of the remaining Trustees hereunder (even if fewer than
two Trustees remain).  Any vacancy (including a vacancy created by an increase
in the number of Trustees) shall be filled, at any regular meeting or at any
special meeting called for that purpose, by a majority of the Trustees.  Any
individual so elected as Trustee shall hold office until the next annual
meeting of shareholders.

         Section 11.  COMPENSATION; FINANCIAL ASSISTANCE.

                 (a)    Compensation.  Trustees shall not receive any stated
salary for their services as Trustees but, by resolution of the Trustees, 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.  Such fixed sums may be paid either
in cash or in shares of the Trust.  Trustees may be reimbursed for expenses of
attendance, if any, at each annual, regular or special meeting of the Trustees
or of any committee thereof; and for their expenses, if any, in connection with
each property visit and any other service or activity 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.

                 (b)      Financial Assistance to Trustees.  The Trust may lend
money to, guarantee an obligation of or otherwise assist a Trustee or a trustee
or director of a direct or indirect subsidiary of the Trust; provided, however,
that such Trustee or other person is also an executive officer of the Trust or
of such subsidiary, or the loan, guarantee or other assistance is in connection
with the purchase of Shares. The loan, guarantee or other assistance may be
with or without interest, unsecured, or secured in any manner that the Board of
Trustees approves, including a pledge of shares.

remove any Trustee in the manner provided in the Declaration of Trust.

         Section 13.  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 14.  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 duties.

         Section 15.  RELIANCE.  Each Trustee, officer, employee and agent of
the Trust shall, in the performance of his 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 upon the books of account or other records of the Trust,
upon an opinion of counsel or upon 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 Trustees or officers of the Trust,
regardless of whether such counsel or expert may also be a Trustee.

         Section 16.  INTERESTED TRUSTEE TRANSACTIONS.  Section 2-419 of the
Maryland General Corporation Law (the "MGCL") shall be available for and apply
to any contract or other transaction between the Trust and any of its Trustees
or between the Trust and any other trust, corporation, firm or other entity in
which any of its Trustees is a trustee or director or has a material financial
interest.

         Section 17.  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 (other than a full-time officer, employee or agent of the Trust), in his
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 or in addition to those of or relating to the Trust.)

transaction) or $75,000,000 (in a series of transactions which are unapproved
by or unreported to the Board), and in either case the Board has approved the
terms and conditions of the securities, divided by the fair market value (as

to be a party and as to which any Trustee knows at the time of commitment that
any of the following persons either is or is entitled to be a party, whether
directly or indirectly, to the transaction or has a sufficiently material
beneficial interest that the interest might reasonably be expected to exert an
influence on the Trustee's judgment if he were called upon to vote on the
transaction: (a) any Trustee or any Related Person of any Trustee; (b) any
person (other than the Trust) of which the Trustee is the owner of more than 5%
of any class of equity securities or is a director, trustee, general partner,

                                       11
<PAGE>   12
                 (c)      Any Trustee who knows of a transaction covered by
Section 8(b) shall immediately notify and provide all material information
about the transaction to the Special Conflicts Committee, which shall
thereafter promptly consider the transaction.  The Board of Trustees, any
Trustee or any officer of the Trust may notify the Special Conflicts Committee
about any transaction that it has reason to believe is covered by Section 8(b)
and, upon request, such Trustee shall provide to the Special Conflicts
Committee all relevant information known or in the control of the referring
person.  Upon receipt of notice pursuant to this paragraph, the Special
Conflicts Committee shall notify the Chairman of the Board and the Secretary of
the Trust in order that the Board of Trustees which, absent the Board's
determination that such notice was improper, shall take no further action with
respect to the transaction unless and until approved, ratified or recommended
to the Board by the Special Conflicts Committee.  The Trust shall not enter
into such transaction without the approval, ratification or recommendation of
the Special Conflicts Committee acting by unanimous written consent or by the
affirmative vote of a majority of its members present and voting at any meeting
thereof (excluding any members disqualified pursuant to Section 8(d)).  Nothing
in this Section 8 shall require approval of fees or other compensation to
Independent Trustees for their service as Trustees.

                 (d)      Any member of the Special Conflicts Committee who is
a party to or who has an interest in the transaction of the type described in
Section 8(b) shall take no part in the deliberations of the Special Conflicts
Committee on the transaction.

                 (e)      For purposes of this Section 8, the following terms
shall have the followings meanings:

                          "Affiliate" means a person or entity that directly or
                 indirectly controls, or is controlled by, or is under common
                 control with, a specified person or entity.

                          "Control", including the terms "controlling" or
                 "under common control with," means the possession, directly or
                 indirectly, of the power to direct or cause the direction of
                 the management and policies of a person, whether by ownership
                 of voting securities, by contract or otherwise.  The
                 beneficial ownership of ten percent or more of securities
                 entitled to be voted generally in the election of directors
                 creates a presumption of control.

                          "Independent Trustee" shall mean a Trustee who is not
                 an officer, employee or agent of the Trust or an Affiliate of
                 the Trust.  For these purposes, Equity Group Investments,
                 L.L.C. and its Affiliates shall be deemed to be Affiliates of
                 the Trust until such time, if any, as the Board shall
                 determine otherwise.

                          "Time of commitment" as to a transaction means the
                 time when the transaction is consummated or, if made pursuant
                 to contract, the time when the Trust becomes contractually
                 obligated so that its unilateral withdrawal from the
                 transaction would entail significant loss, liability or other
                 damage.





                                       12
<PAGE>   13
                          "Related Person" of a Trustee means (a) the spouse
                 (or a parent or sibling thereof) of the Trustee, or a child,
                 grandchild, sibling, parent (or spouse of any thereof) of the
                 Trustee, or an individual sharing the same residence as the
                 Trustee, or a trust or estate of which a Trustee or an
                 individual specified in this definition is a substantial
                 beneficiary or (b) a trust, estate, incompetent, conservatee
                 or minor of which the Trustee is a fiduciary.

         Section 9.       AUDIT COMMITTEE.  The Audit Committee shall be
composed of not less than three Trustees.  The function of the Audit Committee
shall be (i) to review the professional services and independence of the
Trust's independent auditors, (ii) to ensure that the scope of the annual
external audit by the independent auditors of the Trust is sufficiently
comprehensive, (iii) to review, in consultation with the independent auditors
and the internal auditors, the plan and results of the annual external audit,
the adequacy of the Trust's internal control systems and the results of the
Trust's internal audits, (iv) to review, with management and the independent
auditors, the Trust's annual financial statements, financial reporting
practices and the results of each external audit and (v) to undertake
reasonably related activities to those set forth in clauses (i) through (iv) of
this Section.  The Audit Committee shall also have the authority to consider
the qualification of the Trust's independent auditors, to make recommendations
to the Board as to their selection and to review and resolve disputes between
such independent auditors and management relating to the preparation of the
annual financial statements.

         Section 10.  COMPENSATION AND OPTION COMMITTEE.  The Compensation and
Option Committee shall be composed of not less than three Trustees.  The
Compensation and Option Committee shall be authorized to establish the
compensation and benefit arrangements for the officers and key employees of the
Trust and to establish general policy relating to compensation and benefit
arrangements of employees of the Trust.  The Compensation and Option Committee
shall also administer the share plans and compensation programs of the Trust.
The Compensation and Option Committee shall discharge the duties of a
Compensation Committee under the Proxy Rules established by the Securities and
Exchange Commission.

         The Compensation and Option Committee shall be authorized to establish
awards under and administer the Trust's Supplemental Retirement Savings Plan
and compensation programs of the Trust insofar as they relate to executive
officers of the Trust so that any such award or component that is intended to
qualify under Rule 16b-3 under the Exchange Act or that any share plan or
executive compensation program (or a component thereof) or other form of
compensation that is intended to qualify for an exception under such Section
162 (m) (or any successor provision) of the Code does qualify for such
exception.  Composition of the Compensation and Option Committee shall satisfy
requirements set forth under Rule 16(b)(3) under the Exchange Act and Section
162(m) under the Internal Revenue Code.

         Section 11.  COMMITTEE ON TRUST GOVERNANCE.  The Committee on Trust
Governance shall be composed of not less than three Trustees.  The Committee on
Trust Governance shall be authorized to (i) study, and review with management,
the overall effectiveness of the organization of the Board of Trustees and the
conduct of its business,





                                       13

and make appropriate recommendations to the Trustees with regard thereto; (ii)
review the appropriateness and adequacy of information supplied to the Trustees
prior to and during Board of Trustee meetings of the Trustees; (iii) develop,

of Guidelines on Trust Governance Issues in respect to the operation of the
Board of Trustees and propose to the Trustees for their approval from time to
time such revisions therein as the Committee on Trust Governance deems to be
appropriate; (iv) develop and maintain criteria and procedures for the
identification and recruitment or retention of candidates for election or
reelection to serve as Trustees of the Trust, including consideration of the
performance of incumbent Trustees in determining whether to nominate them for

         Section 1.  CONTRACTS.  The Trustees may authorize any officer or
agent to enter into any contract or to execute and deliver any instrument in

shall be valid and binding upon the Trustees and upon the Trust when authorized
or ratified by action of the Trustees.

                                     SHARES

         Section 1. CERTIFICATES; UNCERTIFICATED SHARES.  Unless the Board of
Trustees of the Trust authorizes the issue of some or all of the shares of any
or all of its classes or series without certificates, each shareholder shall be
entitled to a certificate or certificates which shall represent and certify the
number of shares of each class of beneficial interest held by him in the Trust.
Each certificate shall be signed by the chief executive officer, 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 or series of shares, each class or series 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 of the Trust 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.  In lieu of such
statement or summary, the Trust may set forth upon the face or back of the
certificate a statement that the Trust will furnish to any shareholder, upon
request and without charge, a full statement of such information.  At the time
of issue or transfer of shares without certificates, the Trust shall send the
shareholder a written statement of the information required on certificates by
Section 8-203 of Title 8 of the Corporations and Associations Article of the
Annotated Code of Maryland.

         Section 2.  TRANSFERS. Certificates shall be treated as negotiable and
title thereto and to the shares they represent shall be transferred by delivery
thereof duly endorsed or with proper evidence of transfer to the same extent as
those of a Maryland stock corporation.  Upon surrender to the Trust or the
transfer agent of the Trust of a share certificate or uncertificated security
duly endorsed or accompanied by proper evidence of succession, assignment or
authority to transfer, the Trust shall issue a new certificate or
uncertificated security to the person entitled thereto, cancel the old
certificate and record the transaction upon its books.

         The Trust shall be entitled to treat the holder of record of any share
or shares 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 shares
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.

         Notwithstanding the foregoing, transfers of shares of beneficial
interest of the Trust 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
Trustees 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 Trustees may, in his 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 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.  The
Trustees 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 shareholders not less
than ten days, before the date on which the meeting or particular action
requiring such determination of shareholders of record is to be held or taken.

         In lieu of fixing a record date, the Trustees may provide that the
share transfer books shall be closed for a stated period but not longer than 20
days.  If the share transfer books are closed for the purpose of determining
shareholders entitled to notice of or to vote at a meeting of shareholders,
such books shall be closed for at least ten days before the date of such
meeting.

         If no record date is fixed and the share transfer books are not closed
for the determination of shareholders, (a) the record date for the
determination of shareholders





                                       18
<PAGE>   19
entitled to notice of or to vote at a meeting of shareholders shall be at the
close of business on the day on which the notice of meeting is mailed or the
30th day before the meeting, whichever is the closer date to the meeting; and
(b) the record date for the determination of shareholders entitled to receive
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 Trustees, declaring the
dividend or allotment of rights, is adopted.

         When a determination of shareholders entitled to vote at any meeting
of shareholders has been made as provided in this section, such determination
shall apply to any adjournment thereof, except when (i) the determination has
been made through the closing of the transfer books and the stated period of
closing has expired or (ii) the meeting is adjourned to a date more than 120
days after the record date fixed for the original meeting, in either of which
case a new record date shall be determined as set forth herein.

         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.

         Section 6.  FRACTIONAL SHARES; ISSUANCE OF UNITS.  The Trustees 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, the Trustees 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 Trustees 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

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.

the Trust, subject to the provisions of law and the Declaration of Trust.

         Section 2.  CONTINGENCIES.  Before payment of any dividends or other
distributions, there may be set aside out of any funds of the Trust available
for dividends or other distributions such sum or sums as the Trustees may from
time to time, in their absolute discretion, think proper as a reserve fund for
contingencies, for equalizing dividends or other distributions, for repairing
or maintaining any property of the Trust or for such other purpose as the
Trustees shall determine to be in the best interest of the Trust, and the
Trustees may modify or abolish any such reserve in the manner in which it was
created.



                                   ARTICLE X

                     PROHIBITED INVESTMENTS AND ACTIVITIES;

         Notwithstanding anything to the contrary in the Declaration of Trust,

corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise in which a Trustee, officer or employee of the Trust owns more than
a one percent interest or any affiliate of any of the foregoing, any of the
assets or other property of the Trust, except for the acquisition directly or
indirectly of certain properties or interest therein, directly or indirectly,
through entities in which it owns an interest in connection with the initial
public offering of shares by the Trust or pursuant to agreements entered into
in connection with such offering, which properties shall be described in the
prospectus relating to such initial public offering, (ii) make any loan to or
borrow from any of the foregoing persons or (iii) engage in any other
transaction with any of the foregoing persons. Each such transaction will be in
all respects on such terms as are, at the time of the transaction and under the
circumstances then prevailing, fair and reasonable to the Trust.  Subject to
the foregoing and the provisions of the Declaration of Trust, the Board of
Trustees 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.



                                   ARTICLE XI

         Section 1.  SEAL.  The Trustees may authorize the adoption of a seal
by the Trust.  The seal shall have inscribed thereon the name of the Trust and
the year of its formation.  The Trustees 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.

                                  ARTICLE XII

                    INDEMNIFICATION AND ADVANCE OF EXPENSES

         To the maximum extent permitted by Maryland law in effect from time to
time, the Trust shall indemnify (a) any Trustee, officer or shareholder or any
former Trustee, officer or shareholder (including among the foregoing, for all
purposes of this Article XII and without limitation, any individual who, while
a Trustee, officer or shareholder and at the express request of the Trust,
serves or has served another corporation, partnership, joint venture, trust,
employee benefit plan or any other enterprise as a director, officer,
shareholder, partner or trustee of such corporation, partnership, joint
venture, trust, employee benefit plan or other enterprise) who has been
successful, on the merits or otherwise, in the defense of a proceeding to which
he was made a party by reason of service in such capacity, against reasonable
expenses incurred by him in connection with the proceeding, (b) any Trustee or
officer or any former Trustee or officer against any claim or liability to
which he may become subject by reason of such status unless it is established
that (i) his act or omission was material to the matter giving rise to the
proceeding and was committed in bad faith or was the result of active and
deliberate dishonesty, (ii) he actually received an improper personal benefit
in money, property or services or (iii) in the case of a criminal proceeding,
he had reasonable cause to believe that his act or omission was unlawful and
(c) each shareholder or former shareholder against any claim or liability to
which he may become subject by reason of such status.  In addition, the Trust
shall, without requiring a preliminary determination of the ultimate
entitlement to indemnification, pay or reimburse, in advance of final
disposition of a proceeding, reasonable expenses incurred by a Trustee, officer
or shareholder or former Trustee, officer or shareholder made a party to a
proceeding by reason such status, provided that, in the case of a Trustee or
officer, the Trust shall have received (i) a written affirmation by the Trustee
or officer of his good faith belief that he has met the applicable standard of
conduct necessary for indemnification by the Trust as authorized by these
Bylaws and (ii) a written undertaking by or on his behalf to repay the amount
paid or reimbursed by the Trust if it shall ultimately be determined that the
applicable standard of conduct was not met.  The Trust may, with the approval
of its Trustees, provide such indemnification or payment or reimbursement of
expenses to any Trustee, officer or shareholder or any former Trustee, officer
or shareholder who served a predecessor of the Trust and to any employee or
agent of the Trust or a predecessor of the Trust.  Neither the amendment nor
repeal of this Article, nor the adoption or amendment of any other provision of
the Declaration of Trust or these Bylaws inconsistent with this Article, shall
apply to or affect in any respect the applicability of this Article with
respect to any act or failure to act which occurred prior to such amendment,
repeal or adoption.

         Any indemnification or payment or reimbursement of the expenses
permitted by these Bylaws shall be furnished in accordance with the procedures
provided for indemnification or payment or reimbursement of expenses, as the
case may be, under Section 2-418 of the MGCL for directors of Maryland
corporations.  The Trust may provide to Trustees, officers and shareholders
such other and further indemnification or payment





                                       21

or reimbursement of expenses, as the case may be, to the fullest extent
permitted by the MGCL, as in effect from time to time, for directors of
Maryland corporations.

         Whenever any notice is required to be given pursuant to the
Declaration of Trust or Bylaws or pursuant to applicable law, a waiver thereof
in writing, signed by the person or persons 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 person at any meeting
shall constitute a waiver of notice of such meeting, except where such person
attends a meeting for the express purpose of objecting to the transaction of
any business on the ground that the meeting is not lawfully called or convened.

                                  WITNESSETH:

         WHEREAS, the Managing General Partner and the Limited Partners have
entered into the Agreement of Limited Partnership of EOP Operating Limited
Partnership, dated as of July 3, 1997, as the same has been amended through the
date hereof (the "Agreement"); and

         WHEREAS, the Managing General Partner, pursuant to the authority
granted to it under Sections 14.1.A and 14.1.B(4) of the Agreement, as
applicable, desires to amend Sections 7.4, 8.5.C and 14.1.B of the Agreement as
set forth herein, and the Managing General Partner, for itself and, to the
extent this action is taken pursuant to Section 14.1.A of the Agreement, as the
holder of a majority of the Percentage Interests of the Limited Partners, has
approved such amendment.

         NOW, THEREFORE, in consideration of the premises and for other good
and valuable consideration, the receipt and sufficiency of which hereby are
acknowledged, the Managing General Partner hereby amends the Agreement as
follows:

         1.      Amendment to Section 7.4 of Agreement.  Section 7.4 of the
Agreement is hereby amended to add the following new Paragraph F:

                 F.               Funding for Certain Capital Transactions.  In
         the event that the Managing General Partner shall undertake to acquire
         (whether by merger, consolidation, purchase, or otherwise) the assets
         or equity interests of another Person and such acquisition shall
         require the payment of cash by the Managing General Partner (whether
         to such Person or to any other selling party or parties in such
         transaction
<PAGE>   2
         or to one or more creditors, if any, of such Person or such selling
         party or parties), (i) the Partnership shall advance to the Managing
         General Partner the cash required to consummate such acquisition if,
         and to the extent that, such cash is not to be obtained by the
         Managing General Partner through an issuance of Shares described in
         Section 4.2 or pursuant to a transaction described in Section 7.5.B,
         (ii) the Managing General Partner shall immediately, upon consummation
         of such acquisition, transfer to the Partnership (or cause to be
         transferred to the Partnership), in full and complete satisfaction of
         such advance and as required by Section 7.5, the assets or equity
         interests of such Person acquired by the Managing General Partner in
         such acquisition, and (iii) pursuant to and in accordance with Section
         4.2 and Section 7.5.B, the Partnership shall issue to the Managing
         General Partner Partnership Interests and/or rights, options, warrants
         or convertible or exchangeable securities of the Partnership 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 Managing General Partner 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 Managing General Partner engages in a
         transaction in which (x) the Managing General Partner (or a wholly
         owned direct or indirect Subsidiary of the Managing General Partner)
         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 Managing
         General Partner survives such merger, (y) such Operating Entity merges
         with or is otherwise acquired by the Partnership in exchange in whole
         or in part for Partnership Interests, and (z) the Managing General
         Partner 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
         Partnership shall distribute to the Managing General Partner with
         respect to its existing Partnership Interest an amount of cash
         sufficient to complete such transaction and the Managing General
         Partner shall cause the Partnership to cancel a number of Partnership
         Units (rounded to the nearest whole number) held by the Managing
         General Partner equal to the product attained by multiplying the
         number of additional Shares of the Managing General Partner that the
         Managing General Partner would have issued to the Parent Entity or





                                       2
<PAGE>   3
         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.

         2.      Amendment to Section 8.5.C of Agreement.  Section 8.5.C of the
Agreement is hereby amended to add the following proviso at the end of the
existing first sentence of Section 8.5.C:

         ; provided, however, that the Managing General Partner, 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 8.5.C.) to a period
         of not less than ten (10) calendar days (thereby continuing to afford
         the holders of Units the opportunity to redeem Units under Section 8.6
         on or prior to the record date for the shareholder vote on the merger
         transaction) so long as (i) the General Partner Entity will be the
         surviving entity in such merger transaction, (ii) immediately
         following the merger transaction, Persons who held voting securities
         of the General Partner Entity immediately prior to such merger
         transaction will hold, solely by reason of the ownership of voting
         securities of the General Partner Entity immediately prior to the
         merger transaction, voting securities of the General Partner Entity
         representing not less than fifty-one percent (51%) of the total
         combined voting power of all outstanding voting securities of the
         General Partner Entity after such merger, and (iii) in the event that
         in connection with such merger transaction the Partnership will merge
         with another entity, the Partnership will be the surviving entity in
         such merger.

         3.      Amendment to Section 14.1.B of Agreement. Section 14.1.B of
the Agreement hereby is amended by deleting the last sentence of Section 14.1.B
in its entirety and by substituting therefor the following:

         The Managing General Partner shall notify the Limited Partners when
         any action under this Section 14.1.B is taken in the next regular
         communication to the Limited Partners; provided, however, that no
         notice need be given of any amendment of this Agreement to reflect the
         admission, substitution, termination, or withdrawal of Partners in
         accordance with this Agreement (whether or not effected through the
         replacement of Exhibit A with an amended Exhibit A).  For purposes of
         the immediately preceding sentence, notwithstanding any other means by
         which the Managing General Partner may provide any such notice to the
         Limited Partners, such notice requirement shall be deemed to





                                       3
<PAGE>   4
         have been satisfied upon the filing with the Securities and Exchange
         Commission by the Partnership of any amendment to this Agreement
         permitted under this Section 14.1.B as an exhibit to (i) a
         registration statement filed by the Partnership under the Securities
         Act or (ii) any report or other document filed by the Partnership
         under the Exchange Act.

         4.      Definitions; Full Force and Effect.   All capitalized terms
used in this Amendment and not otherwise defined herein shall have the meanings
assigned to them in the Agreement.  Except as modified herein, all terms and
conditions of the Agreement shall remain in full force and effect, which terms
and conditions the Managing General Partner, for itself and the Limited
Partners, hereby ratifies and affirms.

         IN WITNESS WHEREOF, the undersigned has executed and delivered this
Amendment as of the date first set forth above.

                               EQUITY OFFICE PROPERTIES TRUST,
                               a Maryland real estate investment trust, as

                               behalf of the Limited Partners thereof

dilution or anti-dilution as a result of transactions in which Shares are
issued, redeemed or exchanged without a corresponding issuance, redemption or

respect to which value must be determined. The market price for each such
trading day shall be the closing price, regular way, on such day, or if no such
sale takes place on such day, the average of the closing bid and asked prices on
such day. If the outstanding Shares of the General Partner Entity are Publicly
Traded and the Shares Amount includes rights that a holder of Shares would be

Value shall be determined by the General Partner, acting in good faith and based
upon a commercially reasonable estimate of the amount that would be realized by
the Partnership if each asset of the Partnership (and each asset of each
partnership, limited liability company, trust, joint venture or other entity in
which the Partnership owns a direct or indirect interest) were sold to an
unrelated 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 Partnership's
minority interest in any

                                      -15-

purposes of determining the number of additional Partnership Units issuable upon
a Capital Contribution funded by an underwritten public offering or an arm's
length private placement of shares of beneficial interest (or other comparable
equity interest) of the General Partner, the Value of such shares shall be the
public offering or arm's length private placement price per share of such class
of beneficial interest (or other comparable equity interest) sold.

                       CAPITAL CONTRIBUTIONS AND ISSUANCES
                            OF PARTNERSHIP INTERESTS


SECTION 4.1           CAPITAL CONTRIBUTIONS OF THE PARTNERS

                  Prior to the execution of this Agreement, the Partners have
made the Capital Contributions as set forth in Exhibit A. The Partners own
Partnership Units in the amounts set forth in Exhibit A and have Percentage
Interests in the Partnership as set forth in Exhibit A, which number of
Partnership Units and Percentage Interest shall be adjusted in Exhibit A from
time to time by the General Partner to the extent necessary to reflect
accurately redemptions, Capital Contributions, the issuance of additional
Partnership Units or similar events having an effect on a Partner's Percentage
Interest occurring after the date hereof in accordance with the terms of this
Agreement. To the extent the Partnership acquires any property by the merger of
any other Person into the Partnership, Persons who receive Partnership Interests
in exchange for their interests in the Person merging into the Partnership shall
become Partners and shall be deemed to have made Capital Contributions as
provided in the applicable merger agreement and as set forth in Exhibit A. A
number of Partnership Units held by the General Partner equal to one percent
(1%) of the aggregate number of Partnership Units owned by the General Partner
shall be deemed to be the General Partner Partnership Units and shall be the
General Partnership Interest of the General Partner. All other Partnership Units
held by the General Partner shall be deemed to be Limited Partnership Interests
and shall be held by the General Partner in its capacity as a Limited Partner in
the Partnership. Except as provided in Sections 7.5, 10.5, and 13.3 hereof, the
Partners shall have no obligation to make any additional Capital Contributions
or provide any additional funding to the Partnership (whether in the form of
loans, repayments of loans or otherwise). Except as otherwise set forth in
Section 13.3 hereof, no Partner shall have any obligation to restore any deficit
that may exist in its Capital Account, either upon a liquidation of the
Partnership or otherwise.


SECTION 4.2           ISSUANCES OF PARTNERSHIP INTERESTS

                  A. General. The General Partner is hereby authorized to cause
the Partnership from time to time to issue to Partners (including the General
Partner and its Affiliates) or other Persons (including, without limitation, in
connection with the contribution of property to the Partnership) Partnership
Units or other Partnership Interests in one or more classes, or in one or more
series of any of such classes, with such designations, preferences and relative,
participating, optional or other special rights, powers and duties, including
rights, powers and duties senior to Limited Partnership Interests, all as shall
be determined, subject to applicable Delaware law, by the General Partner in its
sole and absolute discretion, including, without limitation, (i) the allocations
of items of Partnership income, gain, loss, deduction and credit to each such
class or series of Partnership Interests, (ii) the right of each such class or
series of Partnership Interests to share in Partnership distributions and (iii)
the rights of each such class or series of Partnership Interests upon
dissolution and liquidation of the Partnership; provided that no such
Partnership Units or other Partnership Interests shall be issued to the General

                                      -18-
<PAGE>   24

Partner unless either (a) the Partnership Interests are issued in connection
with the grant, award or issuance of Shares or other equity interests in the
General Partner having designations, preferences and other rights such that the
economic interests attributable to such Shares or other equity interests are
substantially similar to the designations, preferences and other rights (except
voting rights) of the Partnership Interests issued to the General Partner in
accordance with this Section 4.2.A or (b) the additional Partnership Interests
are issued to all Partners holding Partnership Interests in the same class in
proportion to their respective Percentage Interests in such class. If the
Partnership issues Partnership Interests pursuant to this Section 4.2.A, the
General Partner shall make such revisions to this Agreement (including but not
limited to the revisions described in Section 5.4, Section 6.2 and Section 8.6)
as it deems necessary to reflect the issuance of such Partnership Interests.

                  B. Percentage Interest Adjustments in the Case of Capital
Contributions for Partnership Units. Upon the acceptance of additional Capital
Contributions in exchange for Partnership Units and so long as the Partnership
shall have outstanding more than one class of Partnership Interests, the
Percentage Interest related thereto shall be equal to a fraction, the numerator
of which is equal to the amount of cash, if any, plus the Agreed Value of
Contributed Property, if any, contributed with respect to such additional
Partnership Units and the denominator of which is equal to the sum of (i) the
Deemed Value of the Partnership Interests for all outstanding classes (computed
as of the Business Day immediately preceding the date on which the additional
Capital Contributions are made (an "Adjustment Date")) plus (ii) the aggregate
amount of additional Capital Contributions contributed to the Partnership on
such Adjustment Date in respect of such additional Partnership Units. The
Percentage Interest of each other Partner holding Partnership Interests not
making a full pro rata Capital Contribution shall be adjusted to a fraction the
numerator of which is equal to the sum of (i) the Deemed Partnership Interest
Value of such Limited Partner (computed as of the Business Day immediately
preceding the Adjustment Date) plus (ii) the amount of additional Capital
Contributions (such amount being equal to the amount of cash, if any, plus the
Agreed Value of Contributed Property, if any, so contributed), if any, made by
such Partner to the Partnership in respect of such Partnership Interest as of
such Adjustment Date and the denominator of which is equal to the sum of (i) the
Deemed Value of the Partnership Interests of all outstanding classes (computed
as of the Business Day immediately preceding such Adjustment Date) plus (ii) the
aggregate amount of the additional Capital Contributions contributed to the
Partnership on such Adjustment Date in respect of such additional Partnership
Interests. For purposes of calculating a Partner's Percentage Interest pursuant
to this Section 4.2.B, cash Capital Contributions by the General Partner will be
deemed to equal the cash contributed by the General Partner plus (a) in the case
of cash contributions funded by an offering of any equity interests in or other
securities of the General Partner, the offering costs attributable to the cash
contributed to the Partnership, and (b) in the case of Partnership Units issued
pursuant to Section 7.5.E, an amount equal to the difference between the Value
of the Shares sold pursuant to any Share Option Plan and the net proceeds of
such sale.

                  C. Classes of Partnership Units. Subject to Section 4.2.A
above and Section 4.2.D below, the Partnership shall have two classes of
Partnership Units entitled "Class A Units" and "Class B Units." Either Class A
Units or Class B Units, at the election

                                      -19-
<PAGE>   25

of the General Partner, in its sole and absolute discretion, may be issued to
newly admitted Partners in exchange for the contribution by such Partners of
cash, real estate partnership interests, stock, notes or other assets or
consideration; provided that any Partnership Unit that is not specifically
designated by the General Partner as being of a particular class shall be deemed
to be a Class A Unit. Each Class B Unit shall be converted automatically into a
Class A Unit on the day immediately following the Partnership Record Date for
the Distribution Period (as defined in Section 5.1.C) in which such Class B Unit
was issued, without the requirement for any action by either the Partnership or
the Partner holding the Class B Unit.

                  D. Preferred Units Outstanding. Pursuant to Section 4.2.A, the

                                  DISTRIBUTIONS

SECTION 5.1           REQUIREMENT AND CHARACTERIZATION OF DISTRIBUTIONS

                  A. General. The General Partner shall distribute at least
quarterly an amount equal to one hundred percent (100%) of Available Cash
generated by the Partnership during such quarter or shorter period to the
Partners who are Partners on the Partnership Record Date with respect to such
quarter or shorter period as provided in Sections 5.1.B, 5.1.C and 5.1.D.
Notwithstanding anything to the contrary contained herein, in no event may a
Partner receive a distribution of Available Cash with respect to a Partnership
Unit for a quarter or shorter period if such Partner is entitled to receive a
distribution with respect to a Share for which such Partnership Unit has been
redeemed or exchanged. Unless otherwise expressly provided for herein, in
Attachment A, Attachment B, and Attachment C hereto, with respect to Series A
Preferred Units, Series B Preferred Units, and Series C Preferred Units,
respectively, or in an agreement at the time a new class or series of
Partnership Interests is created in accordance with Article IV hereof, no
Partnership Interest shall be entitled to a distribution in preference to any
other Partnership Interest. The General Partner shall make such reasonable
efforts, as determined by it in its sole and absolute discretion and consistent
with the qualification of the General Partner Entity as a REIT, to distribute
Available Cash (a) to Limited Partners so as to preclude any such distribution
or portion thereof from being treated as part of a sale of property to the
Partnership by a Limited Partner under Section 707 of the Code or the
Regulations thereunder; provided, that, the General Partner and the Partnership
shall not have liability to a Limited Partner under any circumstances as a
result of any distribution to a Limited Partner being so treated, and (b) to the
General Partner in an amount sufficient to enable the General Partner Entity to
make distributions to its shareholders that will enable the General Partner
Entity to (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.

                  B. Method. (i) Each holder of Partnership Interests that is
entitled to any preference in distribution (including, without limitation, the
preferences in distribution set forth in Attachment A, Attachment B, and
Attachment C hereto with respect to Series A Preferred Units, Series B Preferred
Units and Series C Preferred Units, respectively) shall be entitled to a
distribution in accordance with the rights of any such class of Partnership
Interests (and, within such class, pro rata in proportion to the respective
Percentage Interests on such Partnership Record Date); and

                  (ii) To the extent there is Available Cash remaining after the
payment of any preference in distribution in accordance with the foregoing
clause (i), with respect to Partnership Interests that are not entitled to any
preference in distribution, pro rata to each such class in accordance with the
terms of such class (and, within each such class, pro rata in proportion to the
respective Percentage Interests on such Partnership Record Date).

                  C. Distributions 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 Partnership
Record Date for such

                                      -21-
<PAGE>   27

Distribution Period, the General Partner shall allocate the Available Cash with
respect to such Distribution Period available for distribution with respect to
the Class A Units and Class B Units collectively between the Partners who are
holders of Class A Units ("Class A") and the Partners who are holders of Class B
Units ("Class B") as follows:

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



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


                                            (2) Class B shall receive that
                           portion of the Available Cash (the "Class B Share")
                           determined by multiplying the amount of Available
                           Cash by the following fraction:



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


                                            (3) For purposes of the foregoing
                           formulas, (i) "A" equals the number of Class A Units
                           outstanding on the Partnership Record Date for such
                           Distribution Period; (ii) "B" equals the number of
                           Class B Units outstanding on the Partnership 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 Share shall be distributed among Partners holding
Class A Units on the Partnership Record Date for the Distribution Period in
accordance with the number of Class A Units held by each Partner on such
Partnership Record Date; provided that in no event may a Partner receive a
distribution of Available Cash with respect to a Class A Unit if a Partner is
entitled to receive a distribution out of such Available Cash with respect to a
Share for which such Class A Unit has been redeemed or exchanged. The

                                      -22-
<PAGE>   28

Class B Shares shall be distributed among the Partners holding Class B Units on
the Partnership Record Date for the Distribution Period in accordance with the
number of Class B Units held by each Partner on such Partnership 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. If Class B Units which have been issued on different dates are
outstanding on the Partnership Record Date for any Distribution Period, then the
Class B Units issued on each particular date shall be treated as a separate
series of Partnership Units for purposes of making the allocation of Available
Cash for such Distribution Period among the holders of Partnership 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 Partnership Record Date for any
Distribution Period, the allocation formula for each series, "Series B1" and
"Series B2" would be as follows:

                                            (1) Series B1 shall receive that
                           portion of the Available Cash determined by
                           multiplying the amount of Available Cash by the
                           following fraction:


                                  B1 x X1
                    ----------------------------------------
                        (A x Y)+(B1 x X1)+(B2 x X2)

                                            (2) Series B2 shall receive that
                           portion of the Available Cash determined by
                           multiplying the amount of Available Cash by the
                           following fraction:



                                  B2 x X2
                    ----------------------------------------
                        (A x Y)+(B1 x X1)+(B2 x X2)

                                            (3) For purposes of the foregoing
                           formulas the definitions set forth in Section 5.1.C.3
                           remain the same except that (i) "B1" equals the
                           number of Partnership Units in Series B1 outstanding
                           on the Partnership Record Date for such Distribution
                           Period; (ii) "B2" equals the number of Partnership
                           Units

                                      -23-
<PAGE>   29

                           in Series B2 outstanding on the Partnership Record
                           Date for such Distribution Period; (iii) "X1" equals
                           the number of days in the Distribution Period for
                           which the Partnership Units in Series B1 were issued
                           and outstanding; and (iv) "X2" equals the number of
                           days in the Distribution Period for which the
                           Partnership Units in Series B2 were issued and
                           outstanding.

                  E. Minimum Distributions if Shares Not Publicly Traded. In
addition (and without regard to the amount of Available Cash), if the Shares of
the General Partner Entity are not Publicly Traded, the General Partner shall
make cash distributions with respect to the Class A Units at least annually for
each taxable year of the Partnership beginning prior to the fifteenth (15th)
anniversary of the Effective Date in an aggregate amount with respect to each
such taxable year at least equal to 95% of the Partnership's taxable income for
such year allocable to the Class A Units, with such distributions to be made not
later than 60 days after the end of such year.


SECTION 5.2           AMOUNTS WITHHELD

                  All amounts withheld pursuant to the Code or any provisions of
any state or local tax law and Section 10.5 with respect to any allocation,
payment or distribution to the General Partner, the Limited Partners or
Assignees shall be treated as amounts distributed to the General Partner,
Limited Partners or Assignees pursuant to Section 5.1 for all purposes under
this Agreement.


SECTION 5.3           DISTRIBUTIONS UPON LIQUIDATION

                  Proceeds from a Terminating Capital Transaction shall be
distributed to the Partners in accordance with Section 13.2.


SECTION 5.4           REVISIONS TO REFLECT ISSUANCE OF PARTNERSHIP INTERESTS

                  If the Partnership issues Partnership Interests to the General
Partner or any Additional Limited Partner pursuant to Article IV hereof, the
General Partner shall make such revisions to this Article V and Exhibit A as it
deems necessary to reflect the issuance of such additional Partnership Interests
without the requirements for any other consents or approvals.

                                   ARTICLE VI
                                   ALLOCATIONS


SECTION 6.1           ALLOCATIONS FOR CAPITAL ACCOUNT PURPOSES

                  For purposes of maintaining the Capital Accounts and in
determining the rights of the Partners among themselves, the Partnership's items

                                      -24-

deduction (computed in accordance with Exhibit B) shall be allocated among the
Partners 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 C of the Partnership Agreement, Net Income
shall be allocated:

                           (1) first, to the General Partner to the extent that
                           cumulative Net Losses previously allocated the
                           General Partner pursuant to Section 6.1.B(5) exceed
                           cumulative Net Income previously allocated to the
                           General Partner pursuant to this clause (1);

                           (2) next, to each Protected Partner until the
                           cumulative Net Income allocated such Protected
                           Partner under this clause (2) equals the cumulative
                           Net Losses allocated such Protected Partner under
                           Section 6.1.B(4) (and, within the class of Protected
                           Partners, pro rata in proportion to their respective
                           percentages of the cumulative Net Losses allocated
                           all Protected Partners pursuant to Section 6.1.B(4)
                           hereof); and

                           (3) third, to the General Partner until the
                           cumulative Net Income allocated under this clause (3)
                           equals the cumulative Net Losses allocated the
                           General Partner under Section 6.1.B(3);

                           (4) fourth, to the holders of any Partnership
                           Interests that are entitled to any preference in
                           distribution in accordance with the rights of any
                           such class of Partnership Interests until each such
                           Partnership Interest has been allocated, on a
                           cumulative basis pursuant to this clause (4), Net
                           Income equal to the amount of distributions received
                           which are attributable to the preference of such
                           class of Partnership 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

                           (5) finally, with respect to Partnership 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 C, Net Losses shall be allocated -

                           (1) first, to the holders of any Partnership
                           Interests that are entitled to any preference in
                           distribution in accordance with the rights of any
                           such class of Partnership Interests to the extent
                           that any prior allocations of Net Income to such
                           class of Partnership Interests pursuant to Section
                           6.1.A(4) exceed, on a cumulative basis,

                                      -25-
<PAGE>   31

                           distributions with respect to such Partnership
                           Interests pursuant to clause (i) of Section 5.1.B
                           (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);

                           (2) second, with respect to classes of Partnership
                           Interests that are not entitled to any preference in
                           distribution, 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); provided
                           that Net Losses shall not be allocated to any Limited
                           Partner pursuant to this Section 6.1.B to the extent
                           that such allocation would cause such Limited Partner
                           to have an Adjusted Capital Account Deficit (or
                           increase any existing Adjusted Capital Account
                           Deficit) at the end of such taxable year (or portion
                           thereof);

                           (3) third, to the General Partner in an amount equal
                           to the excess of (a) the amount of Recourse
                           Liabilities over (b) the Aggregate Protected Amount;

                           (4) fourth, to and among the Protected Partners, in
                           proportion to their respective Protected Amounts,
                           until such time as the Protected Partners have been
                           allocated cumulative Net Losses pursuant to this
                           clause (4) equal to the Aggregate Protected Amount;
                           and

                           (5) thereafter, to the General Partner.

                  C. Allocation of Nonrecourse Debt. For purposes of Regulation
Section 1.752-3(a), the Partners agree that Nonrecourse Liabilities of the
Partnership in excess of the sum of (i) the amount of Partnership Minimum Gain
and (ii) the total amount of Nonrecourse Built-in Gain shall be allocated by the
General Partner by taking into account facts and circumstances relating to each
Partner's respective interest in the profits of the Partnership. For this
purpose, the General Partner will have discretion in any fiscal year to allocate
such excess Nonrecourse Liabilities among the Partners in any manner permitted
under Code Section 752 and the Regulations thereunder.

                  D. Recapture Income. Any gain allocated to the Partners upon
the sale or other taxable disposition of any Partnership asset shall, to the
extent possible after taking into account other required allocations of gain
pursuant to Exhibit C, be characterized as Recapture Income in the same
proportions and to the same extent as such Partners have been allocated any
deductions directly or indirectly giving rise to the treatment of such gains as
Recapture Income.


SECTION 6.2           REVISIONS TO ALLOCATIONS TO REFLECT ISSUANCE OF
                      PARTNERSHIP INTERESTS

                  If the Partnership issues Partnership Interests to the General
Partner or any Additional Limited Partner pursuant to Article IV hereof, the

                                    jointly with any such Subsidiary or other
                                    Person;

                           (18)     the exercise of any of the powers of the
                                    General Partner enumerated in this Agreement
                                    on behalf of any Person in which the
                                    Partnership does not have any interest
                                    pursuant to contractual or other
                                    arrangements with such Person;

                           (19)     the making, executing and delivering of any
                                    and all deeds, leases, notes, deeds to
                                    secure debt, mortgages, deeds of trust,
                                    security agreements, conveyances, contracts,
                                    guarantees, warranties, indemnities,
                                    waivers, releases or other legal instruments
                                    or agreements in writing necessary or
                                    appropriate in the judgment of the General
                                    Partner for the accomplishment of any of the
                                    powers of the General Partner enumerated in
                                    this Agreement; and

                           (20)     the distribution of cash to acquire
                                    Partnership Units held by a Limited Partner
                                    in connection with a Limited Partner's
                                    exercise of its Redemption Right under
                                    Section 8.6; and

                           (21)     the amendment and restatement of Exhibit A
                                    to reflect accurately at all times the
                                    Capital Contributions and Percentage
                                    Interests of the Partners as the same are
                                    adjusted from time to time to the extent
                                    necessary to reflect redemptions, Capital
                                    Contributions, the issuance of Partnership
                                    Units, the admission of any Additional
                                    Limited Partner or any Substituted Limited
                                    Partner or otherwise, which amendment and
                                    restatement, notwithstanding anything in
                                    this Agreement to the contrary, shall not be
                                    deemed an amendment of this Agreement, as
                                    long as the matter or event

                                      -30-
<PAGE>   36

                                    being reflected in Exhibit A otherwise is
                                    authorized by this Agreement.

                  B. No Approval by Limited Partners. Except as provided in
Section 7.11, each of the Limited Partners agrees that the General Partner is
authorized to execute, deliver and perform the above-mentioned agreements and
transactions on behalf of the Partnership without any further act, approval or
vote of the Partners, notwithstanding any other provision of this Agreement, the
Act or any applicable law, rule or regulation, to the full extent permitted
under the Act or other applicable law. The execution, delivery or performance by
the General Partner or the Partnership of any agreement authorized or permitted
under this Agreement shall not constitute a breach by the General Partner of any
duty that the General Partner may owe the Partnership or the Limited Partners or
any other Persons under this Agreement or of any duty stated or implied by law
or equity.

                  C. Insurance. At all times from and after the date hereof, the
General Partner may cause the Partnership to obtain and maintain (i) casualty,
liability and other insurance on the properties of the Partnership and (ii)
liability insurance for the Indemnitees hereunder and (iii) such other insurance
as the General Partner, in its sole and absolute discretion, determines to be
necessary.

                  D. Working Capital and Other Reserves. At all times from and
after the date hereof, the General Partner may cause the Partnership to
establish and maintain working capital reserves in such amounts as the General
Partner, in its sole and absolute discretion, deems appropriate and reasonable
from time to time, including upon liquidation of the Partnership under Section
13.

                  E. No Obligations to Consider Tax Consequences of Limited
Partners. In exercising their authority under this Agreement, the General
Partner may, but shall be under no obligation to, take into account the tax
consequences to any Partner (including the General Partner) of any action taken
(or not taken) by any of them. The General Partner and the Partnership shall not
have liability to a Limited Partner for monetary damages or otherwise for losses
sustained, liabilities incurred or benefits not derived by such Limited Partner
in connection with such decisions, provided that the General Partner has acted
in good faith and pursuant to its authority under this Agreement.


SECTION 7.2           CERTIFICATE OF LIMITED PARTNERSHIP

                  The General Partner has previously filed the Certificate with
the Secretary of State of Delaware. To the extent that such action is determined
by the General Partner to be reasonable and necessary or appropriate, the
General Partner shall file amendments to and restatements of the Certificate and
do all the things to maintain the Partnership as a limited partnership (or a
partnership in which the limited partners have limited liability) under the laws
of the State of Delaware and each other state, the District of Columbia or other
jurisdiction in which the Partnership may elect to do business or own property.
Subject to the terms of Section 8.5.A(4), the General Partner shall not be
required, before or after filing, to deliver or mail a copy of the Certificate
or any amendment thereto to any Limited Partner. The General Partner shall use
all reasonable efforts to cause to be filed such other certificates or documents
as may be reasonable and necessary or appropriate for

                                      -31-
<PAGE>   37

the formation, continuation, qualification and operation of a limited
partnership (or a partnership in which the limited partners have limited
liability) in the State of Delaware and any other state, the District of
Columbia or other jurisdiction in which the Partnership may elect to do business
or own property.


SECTION 7.3           TITLE TO PARTNERSHIP ASSETS

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


SECTION 7.4           REIMBURSEMENT OF THE GENERAL PARTNER

                  A. No Compensation. Except as provided in this Section 7.4 and
elsewhere in this Agreement (including the provisions of Articles V and VI
regarding distributions, payments and allocations to which it may be entitled),
the General Partner shall not be compensated for its services as the general
partner of the Partnership.

                  B. Responsibility for Partnership Expenses. The Partnership
shall be responsible for and shall pay all expenses relating to the
Partnership's organization, the ownership of its assets and its operations. The
General Partner shall be reimbursed on a monthly basis, or such other basis as
the General Partner may determine in its sole and absolute discretion, for all
expenses it incurs relating to the ownership and operation of, or for the
benefit of, the Partnership (including, without limitation, expenses related to
the operations of the General Partner and to the management and administration
of any Subsidiaries of the General Partner or the Partnership or Affiliates of
the Partnership, such as auditing expenses and filing fees); provided that the
amount of any such reimbursement shall be reduced by (i) any interest earned by
the General Partner with respect to bank accounts or other instruments or
accounts held by it on behalf of the Partnership as permitted in Section 7.5.A
(which interest is considered to belong to the Partnership and shall be paid
over to the Partnership to the extent not applied to reimburse the General
Partner for expenses hereunder); and (ii) any amount derived by the General
Partner from any investments permitted in Section 7.5.A. The General Partner
shall determine in good faith the amount of expenses incurred by it related to
the ownership and operation of, or for the benefit of, the Partnership. If
certain expenses are incurred for the benefit of the Partnership and other
entities (including the General Partner), such expenses will be allocated to the
Partnership and such other entities in such a manner as the General Partner in
its sole and absolute discretion deems fair and

                                      -32-
<PAGE>   38

reasonable. Such reimbursements shall be in addition to any reimbursement to the
General Partner pursuant to Section 10.3.C and as a result of indemnification
pursuant to Section 7.7. All payments and reimbursements hereunder shall be
characterized for federal income tax purposes as expenses of the Partnership
incurred on its behalf, and not as expenses of the General Partner.

                  C. Partnership Interest Issuance Expenses. The General Partner
shall also be reimbursed for all expenses it incurs relating to any issuance of
Partnership Interests, Shares, Debt of the Partnership or the General Partner or
rights, options, warrants or convertible or exchangeable securities pursuant to
Article IV (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 Partners
to constitute expenses of, and for the benefit of, the Partnership.

                  D. Purchases of Shares by the General Partner. If the General
Partner exercises its rights under the 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 General Partner, any employee equity purchase
plan adopted by the General Partner or any similar obligation or arrangement
undertaken by the General Partner in the future, the purchase price paid by the
General Partner for those Shares and any other expenses incurred by the General
Partner in connection with such purchase shall be considered expenses of the
Partnership and shall be reimbursable to the General Partner, subject to the
conditions that: (i) if those Shares subsequently are to be sold by the General
Partner, the General Partner shall pay to the Partnership any proceeds received
by the General Partner for those Shares (provided that a transfer of Shares for
Partnership Units pursuant to Section 8.6 would not be considered a sale for
such purposes); and (ii) if such Shares are not retransferred by the General
Partner within thirty (30) days after the purchase thereof, the General Partner
shall cause the Partnership to cancel a number of Partnership Units (rounded to
the nearest whole Partnership Unit) held by the General Partner equal to 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.

                  E. Reimbursement not a Distribution. If and to the extent any
reimbursement made pursuant to this Section 7.4 is determined for federal income
tax purposes not to constitute a payment of expenses of the Partnership, 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 Partnership and all Partners and shall not be
treated as a distribution for purposes of computing the Partners' Capital
Accounts.

                  F. Funding for Certain Capital Transactions. In the event that
the General Partner shall undertake to acquire (whether by merger,
consolidation, purchase, or otherwise) the assets or equity interests of another
Person and such acquisition shall require the payment of cash by the General
Partner (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

                                      -33-
<PAGE>   39

Person or such selling party or parties), (i) the Partnership shall advance to
the General Partner the cash required to consummate such acquisition if, and to
the extent that, such cash is not to be obtained by the General Partner through
an issuance of Shares described in Section 4.2 or pursuant to a transaction
described in Section 7.5.B, (ii) the General Partner shall immediately, upon
consummation of such acquisition, transfer to the Partnership (or cause to be
transferred to the Partnership), in full and complete satisfaction of such
advance and as required by Section 7.5, the assets or equity interests of such
Person acquired by the General Partner in such acquisition, and (iii) pursuant
to and in accordance with Section 4.2 and Section 7.5.B, the Partnership shall
issue to the General Partner Partnership Interests and/or rights, options,
warrants or convertible or exchangeable securities of the Partnership 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 General Partner 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 General Partner engages in a transaction in which (x) the General
Partner (or a wholly owned direct or indirect Subsidiary of the General Partner)
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 General Partner survives such merger, (y) such
Operating Entity merges with or is otherwise acquired by the Partnership in
exchange in whole or in part for Partnership Interests, and (z) the General
Partner 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 Partnership shall distribute to the
General Partner with respect to its existing Partnership Interest an amount of
cash sufficient to complete such transaction and the General Partner shall cause
the Partnership to cancel a number of Partnership Units (rounded to the nearest
whole number) held by the General Partner equal to the product attained by
multiplying the number of additional Shares of the General Partner that the
General Partner 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 7.5           OUTSIDE ACTIVITIES OF THE GENERAL PARTNER; RELATIONSHIP OF
                      SHARES TO PARTNERSHIP UNITS; FUNDING DEBT

                  A. General. Without the Consent of the Outside Limited
Partners, the General Partner shall not, directly or indirectly, enter into or
conduct any business other than in connection with the ownership, acquisition
and disposition of Partnership Interests as General Partner or Limited Partner
and the management of the business of the Partnership and such activities as are
incidental thereto. Without the Consent of the Outside Limited Partners, the
assets of the General Partner shall be limited to Partnership Interests and
permitted debt obligations of the Partnership (as contemplated by Section
7.5.F), so that Shares and Partnership Units are completely fungible except as
otherwise specifically provided herein; provided that the General Partner shall
be

                                      -34-
<PAGE>   40

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 Partnership to permit the General Partner to
carry out its responsibilities under this Agreement shall be considered to
belong to the Partnership and the interest earned thereon shall, subject to
Section 7.4.B, be applied for the benefit of the Partnership); and, provided
further that, the General Partner shall be permitted to acquire, directly or
through a Qualified REIT Subsidiary or limited liability company, up to a one
percent (1%) interest in any partnership or limited liability company at least
ninety-nine percent (99%) of the equity of which is owned, directly or
indirectly, by the Partnership. The General Partner and any of its Affiliates
may acquire Limited Partnership Interests and shall be entitled to exercise all
rights of a Limited Partner relating to such Limited Partnership Interests.

                  B. Repurchase of Shares. If the General Partner exercises its
rights under the 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 share purchase program adopted by
the General Partner, any employee share purchase plan adopted by the General
Partner or any similar obligation or arrangement undertaken by the General
Partner in the future, then the General Partner shall cause the Partnership to
purchase from the General Partner that number of Partnership Units of the
appropriate class equal to the product obtained by multiplying the number of
Shares purchased by the General Partner times a fraction, the numerator of which
is one and the denominator of which is the Conversion Factor, on the same terms
and for the same aggregate price that the General Partner purchased such Shares.

                  C. Forfeiture of Shares. If the Partnership or the General
Partner acquires Shares as a result of the forfeiture of such Shares under a
restricted or similar share plan, then the General Partner shall cause the
Partnership to cancel that number of Partnership Units equal to the number of
Shares so acquired, and, if the Partnership acquired such Shares, it shall
transfer such Shares to the General Partner for cancellation.

                  D. Issuances of Shares. After the Effective Date, the General
Partner shall not grant, award, or issue any additional Shares (other than
Shares issued pursuant to Section 8.6 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 7.5.A hereof of up to
a one percent (1%) interest in any partnership or limited liability company at
least ninety-nine percent (99%) of the equity of which is owned, directly or
indirectly, by the Partnership), other equity securities of the General Partner,
New Securities or Convertible Funding Debt unless (i) the General Partner shall
cause, pursuant to Section 4.2.A hereof, the Partnership to issue to the General
Partner Partnership Interests or rights, options, warrants or convertible or
exchangeable securities of the Partnership 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 General Partner
transfers to the Partnership, as an additional Capital Contribution, the
proceeds from the grant, award, or issuance of such additional Shares,

                                      -35-
<PAGE>   41

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 General Partner 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 General Partner is expressly authorized, pursuant to Section
4.2.A hereof, to cause the Partnership to issue to the General Partner
corresponding Partnership Interests, as long as (a) the General Partner
concludes in good faith that such issuance is in the interests of the General
Partner and the Partnership (for example, and not by way of limitation, the
issuance of Shares and corresponding Partnership 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 General Partner transfers all proceeds from any such issuance or exercise to
the Partnership as an additional Capital Contribution.

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

                  F. Funding Debt. The General Partner 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 General Partner lend to the Partnership the
net proceeds of such Funding Debt; provided that Convertible Funding Debt shall
be issued pursuant to Section 7.5.D above; and, provided further that, the
General Partner shall not be obligated to lend the net proceeds of any Funding
Debt to the Partnership in a manner that would be inconsistent with the General
Partner's ability to remain qualified as a REIT. If the General Partner enters
into any Funding Debt, the loan to the Partnership 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 7.6           TRANSACTIONS WITH AFFILIATES

                  A. Transactions with Certain Affiliates. Except as expressly
permitted by this Agreement, the Partnership 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 Partner or any Affiliate of the
Partnership that is not also a Subsidiary of the Partnership, except pursuant to
transactions that are on terms that are fair and reasonable and no less
favorable to the Partnership than would be obtained from an unaffiliated third
party.

                  B. Conflict Avoidance. The General Partner is expressly
authorized to enter into, in the name and on behalf of the Partnership, a right
of first opportunity arrangement and other conflict avoidance agreements with
various Affiliates of the

                                      -36-
<PAGE>   42

Partnership and General Partner on such terms as the General Partner, in its
sole and absolute discretion, believes are advisable.

                  C. Benefit Plans Sponsored by the Partnership. The General
Partner in its sole and absolute discretion and without the approval of the
Limited Partners, may propose and adopt on behalf of the Partnership employee
benefit plans funded by the Partnership for the benefit of employees of the
General Partner, the Partnership, Subsidiaries of the Partnership or any
Affiliate of any of them.


SECTION 7.7           INDEMNIFICATION

                  A. General. The Partnership 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 Partnership or
the General Partner or the operation of, or the ownership of property by, the
Partnership or the General Partner 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. Without
limitation, the foregoing indemnity shall extend to any liability of any
Indemnitee, pursuant to a loan guarantee, contractual obligation for any
indebtedness or other obligation or otherwise, for any indebtedness of the
Partnership or any Subsidiary of the Partnership (including, without limitation,
any indebtedness which the Partnership or any Subsidiary of the Partnership has
assumed or taken subject to), and the General Partner is hereby authorized and
empowered, on behalf of the Partnership, to enter into one or more indemnity
agreements consistent with the provisions of this Section 7.7 in favor of any
Indemnitee having or potentially having liability for any such indebtedness. The
termination of any proceeding by judgment, order or settlement does not create a
presumption that the Indemnitee did not meet the requisite standard of conduct
set forth in this Section 7.7.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 7.7.A
with respect to the subject matter of such proceeding. Any indemnification
pursuant to this Section 7.7 shall be made only out of the assets of the
Partnership, and any insurance proceeds from the liability policy covering the
General Partner and any Indemnitee, and neither the General Partner nor any
Limited Partner shall have any obligation to contribute to the capital of the
Partnership or otherwise provide funds to enable the Partnership to fund its
obligations under this Section 7.7.

                  B. Advancement of Expenses. Reasonable expenses expected to be
incurred by an Indemnitee shall be paid or reimbursed by the Partnership in
advance of

                                      -37-
<PAGE>   43

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 Partnership 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 Partnership as
authorized in this Section 7.7.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 7.7 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 Partners, 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 Partnership may purchase and maintain
insurance on behalf of the Indemnitees and such other Persons as the General
Partner shall determine against any liability that may be asserted against or
expenses that may be incurred by such Person in connection with the
Partnership's activities, regardless of whether the Partnership 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 7.7,
(i) excise taxes assessed on an Indemnitee, of for which the Indemnitee is
otherwise found liable, with respect to an ERISA Plan pursuant to applicable law
shall constitute fines within the meaning of this Section 7.7, and (iii) actions
taken or omitted by the Indemnitee with respect to an ERISA 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 ERISA Plan shall be
deemed to be for a purpose which is not opposed to the best interests of the
Partnership.

                  F. No Personal Liability for Limited Partners. In no event may
an Indemnitee subject any of the Partners 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 7.7 because the
Indemnitee had an interest 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 7.7 are for the
benefit of the Indemnitees, their employees, officers, directors, trustees,
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 7.7, or any provision hereof, shall be prospective only
and shall not in any way affect the limitation on the Partnership's liability to
any Indemnitee under this Section 7.7 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 Distributions. If and to the
extent any payments to the General Partner pursuant to this Section 7.7
constitute gross income to the General Partner (as opposed to the repayment of
advances made on behalf of the Partnership), such amounts shall constitute
guaranteed payments within the meaning of Section 707(c) of the Code, shall be
treated consistently therewith by the Partnership and all Partners, and shall
not be treated as distributions for purposes of computing the Partners' Capital
Accounts.

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


SECTION 7.8           LIABILITY OF THE GENERAL PARTNER

                  A. General. Notwithstanding anything to the contrary set forth
in this Agreement, the General Partner shall not be liable for monetary damages
to the Partnership, any Partners or any Assignees for losses sustained,
liabilities incurred or benefits not derived as a result of errors in judgment
or mistakes of fact or law or of any act or omission unless the General Partner
acted in bad faith and the act or omission was material to the matter giving
rise to the loss, liability or benefit not derived.

                  B. No Obligation to Consider Separate Interests of Limited
Partners or Shareholders. The Limited Partners expressly acknowledge that the
General Partner is acting on behalf of the Partnership, that the General Partner
is under no obligation to consider the separate interests of the Limited
Partners (including, without limitation, the tax consequences to Limited
Partners or Assignees) in deciding whether to cause the Partnership to take (or
decline to take) any actions, and that the General Partner shall not be liable
for monetary damages for losses sustained, liabilities incurred or benefits not
derived by Limited Partners in connection with such decisions, provided that the
General Partner has acted in good faith.

                  C. Actions of Agents. Subject to its obligations and duties as
General Partner set forth in Section 7.1.A, the General Partner 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
General Partner shall not be responsible for any misconduct or negligence on the
part of any such agent appointed by the General Partner in good faith.

                  D. Effect of Amendment. Notwithstanding any other provision
contained herein, any amendment, modification or repeal of this Section 7.8 or
any provision hereof shall be prospective only and shall not in any way affect
the limitations on the General Partner's liability to the Partnership and the
Limited Partners under this Section 7.8 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 7.9           OTHER MATTERS CONCERNING THE GENERAL PARTNER

                  A. Reliance on Documents. The General Partner 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 General Partner may consult with
legal counsel, accountants, appraisers, management consultants, investment
bankers 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 the General Partner 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 General Partner 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
General Partner 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 General Partner hereunder.

                  D. Actions to Maintain REIT Status or Avoid Taxation of the
General Partner Entity. Notwithstanding any other provisions of this Agreement
or the Act, any action of the General Partner on behalf of the Partnership or
any decision of the General Partner to refrain from acting on behalf of the
Partnership undertaken in the good faith belief that such action or omission is
necessary or advisable in order (i) to protect the ability of the General
Partner Entity to qualify as a REIT or (ii) to allow the General Partner Entity
to avoid incurring any liability for taxes under Section 857 or 4981 of the
Code, is expressly authorized under this Agreement and is deemed approved by all
of the Limited Partners.

                  E. Actions to Maintain REOC Status. If and so long as the
Partnership Interests of "benefit plan investors" is "significant" (as such
terms, or terms succeeding thereto with the same objective, are used in 29
C.F.R. Section 2510.3-101(f) (such regulation or successor regulation being
known as the "Plan Assets Regulation")), or if necessary so that the underlying
assets of the General Partner will not be "plan assets" (as such term is defined
in the Plan Assets Regulations) of any ERISA Partner, then the General Partner
shall conduct the affairs of the Partnership in such manner so that the
Partnership shall qualify as a "real estate operating company" (REOC"), as that
term is used in the Plan Assets Regulations, and so that the assets of the
Partnership will not be plan assets of any ERISA Partner.

                        (i) If the General Partner, pursuant to this Section
7.09.E, intends to conduct the affairs of the Partnership as a REOC, the General
Partner shall deliver to each ERISA Partner an opinion of counsel reasonably
acceptable to each ERISA Partner and upon which such ERISA Partner may rely with
respect to the Partnership's REOC status

                                      -40-
<PAGE>   46

as of the "initial valuation date" and, if requested in writing by an ERISA
Partner, as of each "annual valuation period" (as those terms, or terms
succeeding thereto with the same objective, are defined in the Plan Assets
Regulation). Such opinion of counsel shall state, (A) as to the opinion
respecting the "initial valuation date," that the Partnership shall qualify as a
REOC for the period beginning on such "initial valuation date" and ending on the
last day of the first "annual valuation period," and (B) as to each annual
opinion respecting each "annual valuation period," that the Partnership shall
qualify as a REOC for the 12-month period following the last day of such "annual
valuation period." Such opinion of counsel may rely upon, among other things, a
certificate of the General Partner as to the exercise of management rights with
respect to one or more investments (other than short-term investments pending
long-term commitment or distribution to investors) during the appropriate period
and as to a description of such investments, and also shall state whether the
Partnership has included in a certification to the opinion a statement to the
effect that on such "initial valuation date" or during such "annual valuation
period" at least 50 percent of Partnership assets (other than short-term
investments pending long-term commitment or distribution to investors), valued
at cost, were invested in real estate investments as described in the Plan
Assets Regulation.

                        (ii) If the opinion described in this subsection is not
provided in the affirmative, or if any ERISA Partner shall obtain and deliver to
the General Partner an opinion of counsel to such ERISA Partner (which opinion
shall be reasonably satisfactory to the General Partner) that there is a
reasonable probability that either the Partnership was not or will not be a REOC
for a period in which either (i) participation by benefit plan investors in the
Partnership is significant or (ii) REOC status is necessary so that the
underlying assets of the General Partner will not be plan assets and the General
Partner does not obtain an opinion to the contrary reasonably acceptable to each
such ERISA Partner within fifteen (15) days of its receipt of the opinion
delivered by the ERISA Partner (it being understood that the existence or
reaffirmation of the opinion delivered by the ERISA Partner to the General
Partner shall not constitute the sole basis of any ERISA Partner's determination
that the opinion delivered within fifteen days by the General Partner is not
reasonably satisfactory), then the General Partner is hereby authorized and
empowered to take such actions as it deems necessary and appropriate to
mitigate, prevent, or cure such adverse consequences as might result to an ERISA
Partner from the underlying assets of the Partnership being assets of an ERISA
Partner or the underlying assets of the General Partner being assets of any
ERISA Partner.


SECTION 7.10          RELIANCE BY THIRD PARTIES

                  Notwithstanding anything to the contrary in this Agreement,
any Person dealing with the Partnership shall be entitled to assume that the
General Partner has full power and authority, without consent or approval of any
other Partner or Person, to encumber, sell or otherwise use in any manner any
and all assets of the Partnership, to enter into any contracts on behalf of the
Partnership and to take any and all actions on behalf of the Partnership, and
such Person shall be entitled to deal with the General Partner as if the General
Partner were the Partnership's sole party in interest, both legally and
beneficially. Each Limited Partner 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 General Partner in connection with any such dealing.
In no event shall any

                                      -41-
<PAGE>   47

Person dealing with the General Partner 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 General Partner or
its representatives. Each and every certificate, document or other instrument
executed on behalf of the Partnership by the General Partner or its
representatives shall be conclusive evidence in favor of any and every Person
relying thereon or claiming thereunder that (i) at the time of the execution and
delivery of such certificate, document or instrument, this Agreement was in full
force and effect, (ii) the Person executing and delivering such certificate,
document or instrument was duly authorized and empowered to do so for and on
behalf of the Partnership, and (iii) such certificate, document or instrument
was duly executed and delivered in accordance with the terms and provisions of
this Agreement and is binding upon the Partnership.


SECTION 7.11          RESTRICTIONS ON GENERAL PARTNER'S AUTHORITY

                  A. Consent Required. The General Partner may not take any
action in contravention of an express prohibition or limitation of this
Agreement without the written Consent of (i) all Partners adversely affected or
(ii) such lower percentage of the Limited Partnership Interests as may be
specifically provided for under a provision of this Agreement or the Act.

                  B. Sale of All Assets of the Partnership. Except as provided
in Article XIII, the General Partner may not, directly or indirectly, cause the
Partnership to sell, exchange, transfer or otherwise dispose of all or
substantially all of the Partnership's assets in a single transaction or a
series of related transactions (including by way of merger (including a
triangular merger), consolidation or other combination with any other Persons)
(i) if such merger, sale or other transaction is in connection with a
Termination Transaction permitted under Section 11.2.B hereof, without the
Consent of the Partners holding at least a majority of the then outstanding
Partnership Units (including any Partnership Units held by the General Partner),
or (ii) otherwise, without the Consent of the Outside Limited Partners.

                  C. Communications Act Investors. Unless otherwise approved in
writing by each affected Communications Act Investor (hereinafter defined), the
General Partner may not, directly or indirectly, cause the Partnership to invest
in any Property or otherwise take any action that (i) would result in the
Communications Act Investor being placed in a position whereby it would have or
be deemed to have the right to act for any third party in selecting or dealing
with any interexchange carrier (which, for purposes hereof, shall include
satellite telecommunication service) in providing long distance service between
local access and transport areas which originates in any State within the region
in which the affected Communications Act Investor (or the operating company
affiliate thereof) provides wireline telephone local exchange service, (but in
no event shall the foregoing be deemed to prohibit the Partnership from
contracting with a third party to perform such functions on a discretionary
basis as part of its property management duties where such activity is a
necessary adjunct to an investment and such activities, in the aggregate, are
not significant in relation to the Partnership's business activities taken as a
whole), or (ii) would cause a significant percentage of the Partnership's gross
income from any Property to be attributable to either the provision or resale of
long distance service

                                      -42-
<PAGE>   48

between local access and transport areas which originates in any State within
the region in which the affected Communications Act Investor (or the operating
company affiliate thereof) provides wireline telephone local exchange service,
or the manufacture of telecommunications, customer premises or related
equipment. In addition, the Partnership will not engage in any
telecommunications activities other than those that may be ancillary to the
ownership or operation of its investments or make an investment in a cable
television system that would violate the cable-telephone cross-ownership
restriction in the Communications Act of 1934, as amended, with regard to the
local exchange service area of a Communications Act Investor (or the operating
company affiliate thereof). Notwithstanding the foregoing, the Partnership is
not precluded from engaging in any telecommunications business or cable business
unless such business is found to place the Communications Act Investor in
violation of law. The General Partner shall have a period of 120 days following
a finding by a court or regulatory body that such a violation exists to use its
reasonable best efforts to prevent or eliminate such violation, including, but
not limited to, correction of the condition giving rise to the violation,
amendment to this Agreement or sale of the relevant property or the interest of
the Communications Act Investor therein. A "Communications Act Investor" is a
Partner or shareholder of the General Partner that has notified the General
Partner that it is subject to the Communications Act of 1934, as amended.


SECTION 7.12          LOANS BY THIRD PARTIES

                  The Partnership may incur Debt, or enter into similar credit,
guarantee, financing or refinancing arrangements for any purpose (including,
without limitation, in connection with any acquisition of property) with any
Person upon such terms as the General Partner determines appropriate.

                                  ARTICLE VIII
                   RIGHTS AND OBLIGATIONS OF LIMITED PARTNERS


SECTION 8.1           LIMITATION OF LIABILITY

                  The Limited Partners shall have no liability under this
Agreement except as expressly provided in this Agreement, including Section
10.5, or under the Act.


SECTION 8.2           MANAGEMENT OF BUSINESS

                  No Limited Partner or Assignee (other than the General
Partner, any of its Affiliates, or any officer, director, employee, partner,
agent or trustee of the General Partner, the Partnership 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 Partnership's
business, transact any business in the Partnership's name or have the power to
sign documents for or otherwise bind the Partnership. The transaction of any
such business by the General Partner, any of its Affiliates or any officer,
director, employee, partner, agent or trustee of the General Partner, the
Partnership or any of their Affiliates, in their capacity as such, shall not
affect, impair or eliminate the limitations on the liability of the Limited
Partners or Assignees under this Agreement.

                                      -43-
<PAGE>   49


SECTION 8.3           OUTSIDE ACTIVITIES OF LIMITED PARTNERS

                  Subject to Section 7.5 hereof, and subject to any agreements
entered into pursuant to Section 7.6.C hereof and to any other agreements
entered into by a Limited Partner or its Affiliates with the Partnership or a
Subsidiary, any Limited Partner (other than the General Partner) and any
officer, director, employee, agent, trustee, Affiliate or shareholder of any
Limited Partner shall be entitled to and may have business interests and engage
in business activities in addition to those relating to the Partnership,
including business interests and activities in direct or indirect competition
with the Partnership. Neither the Partnership nor any Partners shall have any
rights by virtue of this Agreement in any business ventures of any Limited
Partner or Assignee. None of the Limited Partners (other than the General
Partner) or any other Person shall have any rights by virtue of this Agreement
or the partnership relationship established hereby in any business ventures of
any other Person (other than the General Partner 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
Partnership, any Limited Partner or any such other Person, even if such
opportunity is of a character which, if presented to the Partnership, any
Limited Partner or such other Person, could be taken by such Person.


SECTION 8.4           RETURN OF CAPITAL

                  Except pursuant to the right of redemption set forth in
Section 8.6, no Limited Partner shall be entitled to the withdrawal or return of
its Capital Contribution, except to the extent of distributions made pursuant to
this Agreement or upon termination of the Partnership as provided herein. No
Limited Partner or Assignee shall have priority over any other Limited Partner
or Assignee either as to the return of Capital Contributions (except as
permitted by Section 4.2.A) or, except to the extent provided by Exhibit C or as
permitted by Sections 4.2.A, 5.1.B(i), 6.1.A(ii) and 6.1.B(i), or otherwise
expressly provided in this Agreement, as to profits, losses, distributions or
credits.


SECTION 8.5           RIGHTS OF LIMITED PARTNERS RELATING TO THE PARTNERSHIP

                  A. General. In addition to other rights provided by this
Agreement or by the Act, and except as limited by Section 8.5.D, each Limited
Partner shall have the right, for a purpose reasonably related to such Limited
Partner's interest as a limited partner in the Partnership, upon written demand
with a statement of the purpose of such demand and at such Limited Partner's own
expense:

                           (1)      to obtain a copy of the most recent annual
                                    and quarterly reports filed with the

                                    the General Partner Entity or the
                                    Partnership pursuant to the Exchange Act;

                           (2)      to obtain a copy of the Partnership's
                                    federal, state and local income tax returns

                                      -44-
<PAGE>   50

                           (3)      to obtain a current list of the name and
                                    last known business, residence or mailing
                                    address of each Partner;

                           (4)      to obtain a copy of this Agreement and the
                                    Certificate and all amendments thereto,
                                    together with executed copies of all powers
                                    of attorney pursuant to which this
                                    Agreement, the Certificate and all
                                    amendments thereto have been executed; and

                           (5)      to obtain true and full information
                                    regarding the amount of cash and a
                                    description and statement of any other
                                    property or services contributed by each
                                    Partner and which each Partner has agreed to
                                    contribute in the future, and the date on
                                    which each became a Partner.

                  B. Notice of Conversion Factor. The Partnership shall notify
each Limited Partner upon request of the then current Conversion Factor and any
changes that have been made thereto.

                  C. Notice of Extraordinary Transaction of the General Partner
Entity. The General Partner Entity shall not make any extraordinary
distributions of cash or property to its shareholders or effect a merger
(including, without limitation, a triangular merger), a sale of all or
substantially all of its assets or any other similar extraordinary transaction
without notifying the Limited Partners 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 General Partner, 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 8.5.C.) by up to ten (10)
business days (thereby continuing to afford the holders of Units the opportunity
to redeem Units under Section 8.6 on or prior to the record date for the
shareholder vote on the merger transaction) so long as (i) the General Partner
Entity will be the surviving entity in such merger transaction, (ii) immediately
following the merger transaction, Persons who held voting securities of the
General Partner Entity immediately prior to such merger transaction will hold,
solely by reason of the ownership of voting securities of the General Partner
Entity immediately prior to the merger transaction, voting securities of the
General Partner Entity representing not less than fifty one percent (51%) of the
total combined voting power of all outstanding voting securities of the General
Partner Entity after such merger, and (iii) in the event that in connection with
such merger transaction the Partnership will merge with another entity, the
Partnership 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 a Consent of the Partners or (ii) to
require a Consent of the Limited Partners to a transaction that does not
otherwise require Consent under this Agreement. Each Limited Partner agrees, as
a condition to the receipt of the

                                      -45-
<PAGE>   51

notice pursuant hereto, to keep confidential the information set forth therein
until such time as the General Partner Entity has made public disclosure thereof
and to use such information during such period of confidentiality solely for
purposes of determining whether to exercise the Redemption Right; provided,
however, that a Limited Partner may disclose such information to its attorney,
accountant and/or financial advisor for purposes of obtaining advice with
respect to such exercise so long as such attorney, accountant and/or financial
advisor agrees to receive and hold such information subject to this
confidentiality requirement; provided, however, that the General Partner, 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 8.5.C.) to a period of not less than ten
(10) calendar days (thereby continuing to afford the holders of Units the
opportunity to redeem Units under Section 8.6 on or prior to the record date for
the shareholder vote on the merger transaction) so long as (i) the General
Partner Entity will be the surviving entity in such merger transaction, (ii)
immediately following the merger transaction, Persons who held voting securities
of the General Partner Entity immediately prior to such merger transaction will
hold, solely by reason of the ownership of voting securities of the General
Partner Entity immediately prior to the merger transaction, voting securities of
the General Partner Entity representing not less than fifty-one percent (51%) of
the total combined voting power of all outstanding voting securities of the
General Partner Entity after such merger, and (iii) in the event that in
connection with such merger transaction the Partnership will merge with another
entity, the Partnership will be the surviving entity in such merger.

                  D. Confidentiality. Notwithstanding any other provision of
this Section 8.5, the General Partner may keep confidential from the Limited
Partners, for such period of time as the General Partner determine in its sole
and absolute discretion to be reasonable, any information that (i) the General
Partner reasonably believes to be in the nature of trade secrets or other
information the disclosure of which the General Partner in good faith believes
is not in the best interests of the Partnership or could damage the Partnership
or its business or (ii) the Partnership is required by law or by agreements with
unaffiliated third parties to keep confidential.


SECTION 8.6           REDEMPTION RIGHT

                  A. General. (i) Subject to Section 8.6.C, at any time on or
after the first anniversary date of the issuance of a Partnership Unit to a
Limited Partner pursuant to Article IV hereof (which one-year period shall
commence upon the issuance of such Partnership Unit regardless of whether such
Partnership Unit is designated upon issuance as a Class A Unit, a Class B Unit
or otherwise and shall include the period of time from the date such Partnership
Unit is issued to such Limited Partner as other than a Class A Unit until the
date such Partnership Unit is converted automatically to a Class A Unit pursuant
to Section 4.2.C hereof), or on or after such date prior to the expiration of
such one-year period as the General Partner, in its sole and absolute
discretion, designates with respect to any or all Class A Units then
outstanding, the holder of a Partnership Unit (if other than the General Partner
or the General Partner Entity or any Subsidiary of either the General Partner or
the General Partner Entity) shall have the right (the "Redemption Right") to
require the Partnership to redeem such Partnership Unit, with such redemption

                                      -46-
<PAGE>   52

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 Partnership. Any such
Redemption Right shall be exercised pursuant to a Notice of Redemption delivered
to the Partnership (with a copy to the General Partner) by the Limited Partner
who is exercising the Redemption Right (the "Redeeming Partner"). A Limited
Partner may exercise the Redemption Right from time to time, without limitation
as to frequency, with respect to part or all of the Units that it owns, as
selected by the Limited Partner, provided that a Limited Partner may not
exercise the Redemption Right for less than one thousand (1,000) Partnership
Units unless such Redeeming Partner then holds less than one thousand (1,000)
Partnership Units, in which event such Redeeming Partner must exercise the
Redemption Right for all of the Partnership Units held by such Redeeming
Partner.

                        (ii) The Redeeming Partner shall have no right with
respect to any Partnership Units so redeemed to receive any distributions paid
after the Specified Redemption Date with respect to such Partnership Units.

                        (iii) The Assignee of any Limited Partner may exercise
the rights of such Limited Partner pursuant to this Section 8.6, and such
Limited Partner shall be deemed to have assigned such rights to such Assignee
and shall be bound by the exercise of such rights by such Limited Partner's
Assignee. In connection with any exercise of such rights by such Assignee on
behalf of such Limited Partner, the Cash Amount shall be paid by the Partnership
directly to such Assignee and not to such Limited Partner.

                        (iv) If the General Partner Entity provides notice to
the Limited Partners, pursuant to Section 8.5.C hereof, the Redemption Right
shall be exercisable, without regard to whether the Partnership Units have been
outstanding for any specified period, during the period commencing on the date
on which the General Partner Entity 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 (iv) applies, the Specified
Redemption Date is the date on which the Partnership and the General Partner
receive notice of exercise of the Redemption Right, rather than ten (10)
Business Days after receipt of the notice of redemption.

                  B. General Partner Assumption of Right. (i) If a Limited
Partner has delivered a Notice of Redemption, the General Partner may, in its
sole and absolute discretion (subject to the limitations on ownership and
transfer of Shares set forth in the Declaration of Trust), elect to assume
directly and satisfy a Redemption Right by paying to the Redeeming Partner
either the Cash Amount or the Shares Amount, as the General Partner 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 for trading on the exchange or
national market on which the Shares are Publicly Traded and, provided further
that, if the Shares are not Publicly Traded at the time a Redeeming Partner
exercises its Redemption Right, the Redemption Amount shall be paid only in the
form of the Cash Amount unless the Redeeming Partner, in its sole and absolute
discretion, consents to payment of the

                                      -47-
<PAGE>   53

Redemption Amount in the form of the Shares Amount), on the Specified Redemption
Date, whereupon the General Partner shall acquire the Partnership Units offered
for redemption by the Redeeming Partner and shall be treated for all purposes of
this Agreement as the owner of such Partnership Units. Unless the General
Partner, in its sole and absolute discretion, shall exercise its right to assume
directly and satisfy the Redemption Right, the General Partner shall not have
any obligation to the Redeeming Partner or to the Partnership with respect to
the Redeeming Partner's exercise of the Redemption Right. If the General Partner
shall exercise its right to satisfy the Redemption Right in the manner described
in the first sentence of this Section 8.6B and shall fully perform its
obligations in connection therewith, the Partnership shall have no right or
obligation to pay any amount to the Redeeming Partner with respect to such
Redeeming Partner's exercise of the Redemption Right, and each of the Redeeming
Partner, the Partnership and the General Partner shall, for federal income tax
purposes, treat the transaction between the General Partner and the Redeeming
Partner as a sale of the Redeeming Partner's Partnership Units to the General
Partner. Nothing contained in this Section 8.6.B shall imply any right of the
General Partner to require any Limited Partner to exercise the Redemption Right
afforded to such Limited Partner pursuant to Section 8.6.A.

                        (ii) If the General Partner determines to pay the
Redeeming Partner the Redemption Amount in the form of Shares, the total number
of Shares to be paid to the Redeeming Partner in exchange for the Redeeming
Partner's Partnership Units shall be the applicable Shares Amount. If this
amount is not a whole number of Shares, the Redeeming Partner 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 General Partner determines, in its
reasonable discretion, to represent the fair value of the remaining fractional
Share which would otherwise be payable to the Redeeming Partner.

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

                  C. Exceptions to Exercise of Redemption Right. Notwithstanding
the provisions of Sections 8.6.A and 8.6.B, a Partner shall not be entitled to
exercise the Redemption Right pursuant to Section 8.6.A if (but only as long as)
the delivery of Shares to such Partner on the Specified Redemption Date (i)
would be prohibited under the Declaration of Trust or (ii) would be prohibited
under applicable federal or state securities laws or regulations (in each case
regardless of whether the General Partner would in fact assume and satisfy the
Redemption Right).

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

<PAGE>   54

                  E. Additional Partnership Interests. If the Partnership issues
Partnership Interests to any Additional Limited Partner pursuant to Article IV,
the General Partner shall make such revisions to this Section 8.6 as it
determines are necessary to reflect the issuance of such Partnership Interests
(including setting forth any restrictions on the exercise of the Redemption
Right with respect to such Partnership Interests).

                                   ARTICLE IX
                     BOOKS, RECORDS, ACCOUNTING AND REPORTS

SECTION 9.1           RECORDS AND ACCOUNTING

                  The General Partner shall keep or cause to be kept at the
principal office of the Partnership appropriate books and records with respect
to the Partnership's business, including, without limitation, all books and
records necessary to provide to the Limited Partners any information, lists and
copies of documents required to be provided pursuant to Section 9.3. Any records
maintained by or on behalf of the Partnership 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 Partnership shall be
maintained, for financial and tax reporting purposes, on an accrual basis in
accordance with generally accepted accounting principles.

SECTION 9.2           FISCAL YEAR

                  The fiscal year of the Partnership shall be the calendar year.

SECTION 9.3           REPORTS

                  A. Annual Reports. As soon as practicable, but in no event
later than the date on which the General Partner Entity mails its annual report
to its shareholders, the General Partner Entity shall cause to be mailed to each
Limited Partner an annual report, as of the close of the most recently ended
Partnership Year, containing financial statements of the Partnership, or of the
General Partner Entity if such statements are prepared solely on a consolidated
basis with the Partnership, for such Partnership Year, presented in accordance
with generally accepted accounting principles, such statements to be audited by
a nationally recognized firm of independent public accountants selected by the
General Partner Entity.

                  B. Quarterly Reports. If and to the extent that the General
Partner Entity mails quarterly reports to its shareholders, as soon as
practicable, but in no event later than the date on such reports are mailed, the
General Partner Entity shall cause to be mailed to each Limited Partner a report
containing unaudited financial statements, as of the last day of such calendar
quarter, of the Partnership, or of the General Partner Entity if such statements
are prepared solely on a consolidated basis with the Partnership,

                                      -49-
<PAGE>   55

and such other information as may be required by applicable law or regulation,
or as the General Partner determines to be appropriate.

                                    ARTICLE X
                                   TAX MATTERS

SECTION 10.1          PREPARATION OF TAX RETURNS

                  The General Partner shall arrange for the preparation and
timely filing of all returns of Partnership income, gains, deductions, losses
and other items required of the Partnership for federal and state income tax
purposes and shall use all reasonable efforts to furnish, within ninety (90)
days of the close of each taxable year, the tax information reasonably required
by Limited Partners for federal and state income tax reporting purposes.

SECTION 10.2          TAX ELECTIONS

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

SECTION 10.3          TAX MATTERS PARTNER

                  A. General. The General Partner shall be the "tax matters
partner" of the Partnership for federal income tax purposes. Pursuant to Section
6223(c)(3) of the Code, upon receipt of notice from the IRS of the beginning of
an administrative proceeding with respect to the Partnership, the tax matters
partner shall furnish the IRS with the name, address, taxpayer identification
number and profit interest of each of the Limited Partners and any Assignees;
provided, however, that such information is provided to the Partnership by the
Limited Partners.

                  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 Partnership
                             items required to be taken into account by a
                             Partner 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 Partners, except that such
                             settlement agreement shall not bind any
                             Partner (i) who

                                      -50-
<PAGE>   56

                              (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 Partner 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)      if a notice of a final administrative
                              adjustment at the Partnership level of any
                              item required to be taken into account by a
                              Partner 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 Partnership's
                              principal place of business is located;

                     (3)      to intervene in any action brought by any
                              other Partner 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;

                     (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 Partner for
                              tax purposes, or an item affected by such
                              item; and

                     (6)      to take any other action on behalf of the
                              Partners of the Partnership 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
General Partner set forth in Section 7.7 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 Partnership. Nothing herein
shall be construed to restrict the Partnership from engaging an accounting firm
and/or law firm to assist the tax matters

                                      -51-
<PAGE>   57

partner in discharging its duties hereunder, so long as the compensation paid by
the Partnership for such services is reasonable.

SECTION 10.4          ORGANIZATIONAL EXPENSES

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

SECTION 10.5          WITHHOLDING

                  Each Limited Partner hereby authorizes the Partnership to
withhold from or pay on behalf of or with respect to such Limited Partner any
amount of federal, state, local, or foreign taxes that the General Partner
determines that the Partnership is required to withhold or pay with respect to
any amount distributable or allocable to such Limited Partner pursuant to this
Agreement, including, without limitation, any taxes required to be withheld or
paid by the Partnership pursuant to Section 1441, 1442, 1445, or 1446 of the
Code. Any amount paid on behalf of or with respect to a Limited Partner shall
constitute a loan by the Partnership to such Limited Partner, which loan shall
be repaid by such Limited Partner within fifteen (15) days after notice from the
General Partner that such payment must be made unless (i) the Partnership
withholds such payment from a distribution which would otherwise be made to the
Limited Partner or (ii) the General Partner determines, in its sole and absolute
discretion, that such payment may be satisfied out of the available funds of the
Partnership which would, but for such payment, be distributed to the Limited
Partner. Any amounts withheld pursuant to the foregoing clauses (i) or (ii)
shall be treated as having been distributed to such Limited Partner. Each
Limited Partner hereby unconditionally and irrevocably grants to the Partnership
a security interest in such Limited Partner's Partnership Interest to secure
such Limited Partner's obligation to pay to the Partnership any amounts required
to be paid pursuant to this Section 10.5. If a Limited Partner fails to pay any
amounts owed to the Partnership pursuant to this Section 10.5 when due, the
General Partner may, in its sole and absolute discretion, elect to make the
payment to the Partnership on behalf of such defaulting Limited Partner, and in
such event shall be deemed to have loaned such amount to such defaulting Limited
Partner and shall succeed to all rights and remedies of the Partnership as
against such defaulting Limited Partner (including, without limitation, the
right to receive distributions). Any amounts payable by a Limited Partner
hereunder shall bear interest at 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 (but not higher than
the maximum lawful rate under the laws of the State of Illinois) from the date
such amount is due (i.e., fifteen (15) days after demand) until such amount is
paid in full. Each Limited Partner shall take such actions as the Partnership or
the General Partner shall request to perfect or enforce the security interest
created hereunder.

                            TRANSFERS AND WITHDRAWALS

SECTION 11.1          TRANSFER

                  A. Definition. The term "transfer," when used in this Article
XI with respect to a Partnership Interest or a Partnership Unit, shall be deemed
to refer to a transaction by which the General Partner purports to assign all or
any part of its General Partnership Interest to another Person or by which a
Limited Partner purports to assign all or any part of its Limited Partnership
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 XI does not include
any redemption or repurchase of Partnership Units by the Partnership from a
Partner or acquisition of Partnership Units from a Limited Partner by the
General Partner pursuant to Section 8.6 or otherwise. No part of the interest of
a Limited Partner 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.

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

SECTION 11.2          TRANSFERS OF PARTNERSHIP INTERESTS OF GENERAL PARTNER

                  A. Except for transfers of Partnership Units to the
Partnership as provided in Section 7.5 or Section 8.6, the General Partner may
not transfer any of its Partnership Interest (including both its General
Partnership Interest and its Limited Partnership Interest) except in connection
with a transaction described in Section 11.2.B or as otherwise expressly
permitted under this Agreement, nor shall the General Partner withdraw as the
General Partner except in connection with a transaction described in Section
11.2.B.

                  B. The General Partner 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 the Termination Transaction has
been approved by the Consent of the Partners holding at least a majority of the
then outstanding Partnership Units (including any Partnership Units held by the
General Partner) and in connection with which all Limited Partners either will
receive, or will have the right to elect to receive, for each Partnership 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 Partnership Unit in
consideration of one such Share at any time during the period

                                      -53-
<PAGE>   59

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 Shares, each holder of
Partnership Units shall receive, or shall have the right to elect to receive
without any right of Consent 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 Partnership Units immediately prior to the expiration of such purchase,
tender or exchange offer and had thereupon accepted such purchase, tender or

SECTION 11.3          LIMITED PARTNERS' RIGHTS TO TRANSFER

                  A. General. Subject to the provisions of Sections 11.3.C,
11.3.D, 11.3.E, 11.4 and 11.6, a Limited Partner (other than the General
Partner) may transfer with or without the consent of the General Partner, all or
any portion of its Partnership Interest, or any of such Limited Partner's rights
as a Limited Partner, provided that prior written notice of such proposed
transfer is delivered to the General Partner. Notwithstanding the foregoing, any
Limited Partner may, at any time, without the consent of the General Partner,
(i) transfer all or any portion of its Partnership Interest to the General
Partner, (ii) transfer all or any portion of its Partnership Interest to an
Affiliate, another original Limited Partner or to an Immediate Family member,
subject to the provisions of Section 11.6, (iii) transfer all or any portion of
its Partnership Interest to a trust for the benefit of a charitable beneficiary
or to a charitable foundation, subject to the provisions of Section 11.6, and
(iv) subject to the provisions of Section 11.6, pledge (a "Pledge") all or any
portion of its Partnership Interest to a lending institution, which is not an
Affiliate of such Limited Partner, as collateral or security for a bona fide
loan or other extension of credit, and transfer such pledged Partnership
Interest to such lending institution in connection with the exercise of remedies
under such loan or extension or credit. Each Limited Partner or Assignee
(resulting from a transfer made pursuant to clauses (i) - (iv) of the proviso of
the preceding sentence) shall have the right to transfer all or any portion of
its Partnership Interest, subject to the provisions of Section 11.6 and the
satisfaction of each of the following conditions (in addition to the right of
each such Limited Partner or Assignee to continue to make any such transfer
permitted by clauses (i) - (iv) of such proviso without satisfying either of the
following conditions):

                  (a)    GENERAL PARTNER RIGHT OF FIRST REFUSAL. The
                         transferring Partner shall give written notice of the
                         proposed transfer to the General Partner, which notice
                         shall state (i) the identity of the proposed
                         transferee, and (ii) the amount and type of
                         consideration proposed to be received for the
                         transferred Partnership Units. The General Partner
                         shall have ten (10) days upon which to give the
                         transferring Partner notice of its election to acquire
                         the Partnership Units on the proposed terms. If it so
                         elects, it shall purchase the Partnership Units on such
                         terms within ten (10) days after giving notice of such
                         election. If it does not so elect, the transferring
                         Partner may transfer such Partnership Units to a third
                         party, on

                                      -54-
<PAGE>   60

                         economic terms no more favorable to the transferee than
                         the proposed terms, subject to the other conditions of
                         this Section 11.3.

                  (b)    QUALIFIED TRANSFEREE. Any transfer of a Partnership
                         Interest shall be made only to Qualified Transferees.

                  It is a condition to any transfer otherwise permitted
hereunder (excluding Pledges of a Partnership Interest, but including any
transfer of the pledged Partnership Interest, whether to the secured party or
otherwise, pursuant to the secured party's exercise of its remedies under such
Pledge or the related loan or extension of credit) that the transferee assumes
by operation of law or express agreement all of the obligations of the
transferor Limited Partner under this Agreement with respect to such transferred
Partnership Interest and no such transfer (other than pursuant to a statutory
merger or consolidation wherein all obligations and liabilities of the
transferor Partner are assumed by a successor corporation by operation of law)
shall relieve the transferor Partner of its obligations under this Agreement
without the approval of the General Partner, in its reasonable discretion.
Notwithstanding the foregoing, any transferee of any transferred Partnership
Interest shall be subject to any and all ownership limitations contained in the
Declaration of Trust. Any transferee, whether or not admitted as a Substituted
Limited Partner, shall take subject to the obligations of the transferor
hereunder. Unless admitted as a Substitute Limited Partner, no transferee,
whether by a voluntary transfer, by operation of law or otherwise, shall have
rights hereunder, other than the rights of an Assignee as provided in Section
11.5.

                  B. Incapacitated Limited Partners. If a Limited Partner is
subject to Incapacity, the executor, administrator, trustee, committee,
guardian, conservator or receiver of such Limited Partner's estate shall have
all the rights of a Limited Partner, but not more rights than those enjoyed by
other Limited Partners for the purpose of settling or managing the estate and
such power as the Incapacitated Limited Partner possessed to transfer all or any
part of its interest in the Partnership. The Incapacity of a Limited Partner, in
and of itself, shall not dissolve or terminate the Partnership.

                  C. No Transfers Violating Securities Laws. The General Partner
may prohibit any transfer of Partnership Units by a Limited Partner unless it
receives a written opinion of legal counsel (which opinion and counsel shall be
reasonably satisfactory to the Partnership) to such Limited Partner 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 Partnership or the Partnership Unit or, at
the option of the Partnership, an opinion of legal counsel to the Partnership to
the same effect.

                  D. No Transfers Affecting Tax Status of Partnership. No
transfer of Partnership Units by a Limited Partner (including a redemption or
exchange pursuant to Section 8.6) may be made to any Person if (i) in the
opinion of legal counsel for the Partnership, it would result in the Partnership
being treated as an association taxable as a corporation for federal income tax
purposes or would result in a termination of the

                                      -55-
<PAGE>   61

Partnership for federal income tax purposes (except as a result of the
redemption or exchange for Shares of all Partnership Units held by all Limited
Partners other than the General Partner or the General Partner Entity or any
Subsidiary of the General Partner or the General Partner Entity or pursuant to a
transaction expressly permitted under Section 7.11.B or Section 11.2), (ii) in
the opinion of legal counsel for the Partnership, it would adversely affect the
ability of the General Partner Entity to continue to qualify as a REIT or would
subject the General Partner Entity 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 (provided
that this clause (iii) shall not be the basis for limiting or restricting in any
manner the exercise of the Redemption Right under Section 8.6 unless, and only
to the extent that, outside tax counsel provides to the General Partner an
opinion to the effect that, in the absence of such limitation or restriction,
there is a significant risk that the Partnership will be treated as a "publicly
traded partnership" and, by reason thereof, taxable as a corporation).

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

SECTION 11.4          SUBSTITUTED LIMITED PARTNERS

                  A. Consent of General Partner. No Limited Partner shall have
the right to substitute a transferee as a Limited Partner in its place. The
General Partner shall, however, have the right to consent to the admission of a
transferee of the interest of a Limited Partner pursuant to this Section 11.4 as
a Substituted Limited Partner, which consent may be given or withheld by the
General Partner in its sole and absolute discretion. The General Partner's
failure or refusal to permit a transferee of any such interests to become a
Substituted Limited Partner shall not give rise to any cause of action against
the Partnership or any Partner. The General Partner hereby grants its consent to
the admission as a Substituted Limited Partner to any bona fide financial
institution that loans money or otherwise extends credit to a holder of Units
and thereafter becomes the owner of such Units pursuant to the exercise by such
financial institution of its rights under a Pledge of such Units granted in
connection with such loan or extension of credit.

                  B. Rights of Substituted Limited Partner. A transferee who has
been admitted as a Substituted Limited Partner in accordance with this Article
XI shall have all the rights and powers and be subject to all the restrictions
and liabilities of a Limited Partner under this Agreement. The admission of any
transferee as a Substituted Limited Partner shall be conditioned upon the
transferee executing and delivering to the Partnership an acceptance of all the
terms and conditions of this Agreement (including,

                                      -56-
<PAGE>   62

without limitation, the provisions of Section 15.11) and such other documents or
instruments as may be required to effect the admission.

                  C. Amendment of Exhibit A. Upon the admission of a Substituted
Limited Partner, the General Partner shall amend Exhibit A to reflect the name,
address, Capital Account, number of Partnership Units, and Percentage Interest
of such Substituted Limited Partner and to eliminate or adjust, if necessary,
the name, address, Capital Account and Percentage Interest and interest of the
predecessor of such Substituted Limited Partner.

SECTION 11.5          ASSIGNEES

                  If the General Partner, in its sole and absolute discretion,
does not consent to the admission of any permitted transferee under Section 11.3
as a Substituted Limited Partner, as described in Section 11.4, such transferee
shall be considered an Assignee for purposes of this Agreement. An Assignee
shall be entitled to all the rights of an assignee of a limited partnership
interest under the Act, including the right to receive distributions from the
Partnership and the share of Net Income, Net Losses, gain, loss and Recapture
Income attributable to the Partnership Units assigned to such transferee, and
shall have the rights granted to the Limited Partners under Section 8.6, but
shall not be deemed to be a holder of Partnership Units for any other purpose
under this Agreement, and shall not be entitled to vote such Partnership Units
in any matter presented to the Limited Partners for a vote (such Partnership
Units being deemed to have been voted on such matter in the same proportion as
all other Partnership Units held by Limited Partners are voted). If any such
transferee desires to make a further assignment of any such Partnership Units,
such transferee shall be subject to all the provisions of this Article XI to the
same extent and in the same manner as any Limited Partner desiring to make an
assignment of Partnership Units.

SECTION 11.6          GENERAL PROVISIONS

                  A. Withdrawal of Limited Partner. No Limited Partner may
withdraw from the Partnership other than as a result of a permitted transfer of
all of such Limited Partner's Partnership Units in accordance with this Article
XI or pursuant to redemption of all of its Partnership Units under Section 8.6.

                  B. Termination of Status as Limited Partner. Any Limited
Partner who shall transfer all of its Partnership Units in a transfer permitted
pursuant to this Article XI or pursuant to redemption of all of its Partnership
Units under Section 8.6 shall cease to be a Limited Partner.

                  C. Timing of Transfers. Transfers pursuant to this Article XI
may only be made upon three business days prior notice, unless the General
Partner otherwise agrees.

                  D. Allocations. If any Partnership Interest is transferred
during any quarterly segment of the Partnership's fiscal year in compliance with
the provisions of this Article XI or redeemed or transferred pursuant to Section
8.6, Net Income, Net Losses,

                                      -57-
<PAGE>   63

each item thereof and all other items attributable to such interest for such
fiscal year shall be divided and allocated between the transferor Partner and
the transferee Partner 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 General Partner, in its sole and
absolute discretion, elects to adopt a daily, weekly, or a monthly proration
period, in which event Net Income, Net Losses, each item thereof and all other
items attributable to such interest for such fiscal year shall be prorated based
upon the applicable method selected by the General Partner). Solely for purposes
of making such allocations, each of such items for the calendar month in which
the transfer or redemption occurs shall be allocated to the Person who is a
Partner as of midnight on the last day of said month. All distributions of
Available Cash attributable to any Partnership Unit with respect to which the
Partnership Record Date is before the date of such transfer, assignment or
redemption shall be made to the transferor Partner or the Redeeming Partner, 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
Partnership Unit shall be made to the transferee Partner.

                  E. Additional Restrictions. In addition to any other
restrictions on transfer herein contained, including without limitation the
provisions of this Article XI, in no event may any transfer or assignment of a
Partnership Interest by any Partner (including pursuant to Section 8.6) be made
without the express consent of the General Partner, in its sole and absolute
discretion, (i) to any person or entity who lacks the legal right, power or
capacity to own a Partnership Interest; (ii) in violation of applicable law;
(iii) of any component portion of a Partnership Interest, such as the Capital
Account, or rights to distributions, separate and apart from all other
components of a Partnership Interest; (iv) if in the opinion of legal counsel to
the Partnership such transfer would cause a termination of the Partnership for
federal or state income tax purposes (except as a result of the redemption or
exchange for Shares of all Partnership Units held by all Limited Partners or
pursuant to a transaction expressly permitted under Section 7.11.B or Section
11.2); (v) if in the opinion of counsel to the Partnership, such transfer would
cause the Partnership to cease to be classified as a partnership for federal
income tax purposes (except as a result of the redemption or exchange for Shares
of all Partnership Units held by all Limited Partners or pursuant to a
transaction expressly permitted under Section 7.11.B or Section 11.2); (vi) if
such transfer would cause the Partnership Interests of "benefit plan investors"
to become "significant," as those terms are used in Section 7.9.E., or would
cause the Partnership to become, with respect to any employee benefit plan
subject to Title I of ERISA, a "party-in-interest" (as defined in Section 3(14)
of ERISA) or a "disqualified person" (as defined in Section 4975(c) of the
Code); (vii) if such transfer would, in the opinion of counsel to the
Partnership, cause any portion of the assets of the Partnership to constitute
assets of any employee benefit plan pursuant to Department of Labor Regulations
Section 2510.1-101; (viii) if such transfer requires the registration of such
Partnership Interest pursuant to any applicable federal or state securities
laws; (ix) if 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 or such transfer causes the Partnership
to become a "publicly traded partnership," as such term is defined in Section
469(k)(2) or Section 7704(b) of the Code (provided that this clause (ix) shall
not be the basis for limiting or restricting in any manner the exercise of the
Redemption Right under Section 8.6 unless, and only to the extent that, outside
tax

                                      -58-
<PAGE>   64

counsel provides to the General Partner an opinion to the effect that, in the
absence of such limitation or restriction, there is a significant risk that the
Partnership will be treated as a "publicly traded partnership" and, by reason
thereof, taxable as a corporation); (x) if such transfer subjects the
Partnership to regulation under the Investment Company Act of 1940, the
Investment Advisors Act of 1940 or ERISA, each as amended; (xi) such transfer
could adversely affect the ability of the General Partner Entity to remain
qualified as a REIT; or (xii) if in the opinion of legal counsel for the
transferring Partner (which opinion and counsel shall be reasonably satisfactory
to the Partnership) or legal counsel for the Partnership, such transfer would
adversely affect the ability of the General Partner Entity to qualify as a REIT
or subject the General Partner Entity to any taxes under Section 857 or Section
4981 of the Code.

                  F. Avoidance of "Publicly Traded Partnership" Status. The
General Partner shall monitor the transfers of interests in the Partnership 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 Partnership 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 General Partner shall take all steps
reasonably necessary or appropriate to prevent any trading of interests or any
recognition by the Partnership 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 General
Partner to limit or restrict in any manner the right of any holder of a
Partnership Unit to exercise the Redemption Right in accordance with the terms
of Section 8.6 unless, and only to the extent that, outside tax counsel provides
to the General Partner an opinion to the effect that, in the absence of such
limitation or restriction, there is a significant risk that the Partnership will
be treated as a "publicly traded partnership" and, by reason thereof, taxable as
a corporation.

                              ADMISSION OF PARTNERS

SECTION 12.1          ADMISSION OF A SUCCESSOR GENERAL PARTNER

                  A successor to all of the General Partner's General
Partnership Interest pursuant to Section 11.2 who is proposed to be admitted as
a successor General Partner shall be admitted to the Partnership as the General
Partner, effective upon such transfer. Any such successor shall carry on the
business of the Partnership without dissolution. In such case, the admission
shall be subject to such successor General Partner executing and delivering to
the Partnership an acceptance of all of the terms and conditions of this
Agreement and such other documents or instruments as may be required to effect
the admission.

SECTION 12.2          ADMISSION OF ADDITIONAL LIMITED PARTNERS

                  A. General. No Person shall be admitted as an Additional
Limited Partner without the consent of the General Partner, which consent shall
be given or withheld in the General Partner's sole and absolute discretion. A
Person who makes a Capital Contribution to the Partnership in accordance with
this Agreement, including without limitation, under Section 4.1.C, or who
exercises an option to receive Partnership Units shall be admitted to the
Partnership as an Additional Limited Partner only with the consent of the
General Partner and only upon furnishing to the General Partner (i) evidence of
acceptance in form satisfactory to the General Partner of all of the terms and
conditions of this Agreement, including, without limitation, the power of
attorney granted in Section 15.11 and (ii) such other documents or instruments
as may be required in the discretion of the General Partner to effect such
Person's admission as an Additional Limited Partner. The admission of any Person
as an Additional Limited Partner shall become effective on the date upon which
the name of such Person is recorded on the books and records of the Partnership,
following the consent of the General Partner to such admission.

                  B. Allocations to Additional Limited Partners. If any
Additional Limited Partner is admitted to the Partnership on any day other than
the first day of a Partnership Year, then Net Income, Net Losses, each item
thereof and all other items allocable among Partners and Assignees for such
Partnership Year shall be allocated among such Additional Limited Partner and
all other Partners and Assignees by taking into account their varying interests
during the Partnership Year in accordance with Section 706(d) of the Code, using
the interim closing of the books method (unless the General Partner, 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 General Partner).
Solely for purposes of making such allocations, each of such items for the
calendar month in which an admission of any Additional Limited Partner occurs
shall be allocated among all the Partners and Assignees including such
Additional Limited Partner. All distributions of Available Cash with respect to
which the Partnership Record Date is before the date of such admission shall be
made solely to Partners and Assignees other than the Additional Limited Partner,
and all distributions of Available Cash thereafter shall be made to all the
Partners and Assignees including such Additional Limited Partner.

SECTION 12.3          AMENDMENT OF AGREEMENT AND CERTIFICATE OF LIMITED
                      PARTNERSHIP

                  For the admission to the Partnership of any Partner, the
General Partner shall take all steps necessary and appropriate under the Act to
amend the records of the Partnership and, if necessary, to prepare as soon as
practical an amendment of this Agreement (including an amendment of Exhibit A)
and, if required by law, shall prepare and file an amendment to the Certificate
and may for this purpose exercise the power of attorney granted pursuant to
Section 15.11 hereof.

                           DISSOLUTION AND LIQUIDATION

SECTION 13.1          DISSOLUTION

                  The Partnership shall not be dissolved by the admission of
Substituted Limited Partners or Additional Limited Partners or by the admission
of a successor General Partner in accordance with the terms of this Agreement.
Upon the withdrawal of the General Partner, any successor General Partner shall
continue the business of the Partnership. The Partnership shall dissolve, and
its affairs shall be wound up, upon the first to occur of any of the following
("Liquidating Events"):

                           (i) the expiration of its term as provided in Section
2.4 hereof;

                           (ii) an event of withdrawal of the General Partner,
as defined in the Act (other than an event of bankruptcy), unless within ninety
(90) days after the withdrawal a "majority in interest" (as defined below) of
the remaining Partners Consent in writing to continue the business of the
Partnership and to the appointment, effective as of the date of withdrawal, of a
substitute General Partner;

                           (iii) through December 31, 2046, an election to
dissolve the Partnership made by the General Partner with the consent of Limited
Partners who hold ninety percent (90%) of the outstanding Units held by Limited
Partners (including Units held by the General Partner);

                           (iv) an election to dissolve the Partnership made by
the General Partner, in its sole and absolute discretion after December 31,
2046;

                           (v) entry of a decree of judicial dissolution of the
Partnership pursuant to the provisions of the Act;

                           (vi) the sale of all or substantially all of the
assets and properties of the Partnership for cash or for marketable securities;
or

                           (vii) a final and non-appealable judgment is entered
by a court of competent jurisdiction ruling that the General Partner is bankrupt
or insolvent, or a final and non-appealable order for relief is entered by a
court with appropriate jurisdiction against the General Partner, in each case
under any federal or state bankruptcy or insolvency laws as now or hereafter in
effect, unless prior to or at the time of the entry of such order or judgment a
"majority in interest" (as defined below) of the remaining Partners Consent in
writing to continue the business of the Partnership and to the appointment,
effective as of a date prior to the date of such order or judgment, of a
substitute General Partner.

                  As used herein, a "majority in interest" shall refer to
Partners (excluding the General Partner) who hold more than fifty percent (50%)
of the outstanding Percentage Interests not held by the General Partner.

SECTION 13.2          WINDING UP

                  A. General. Upon the occurrence of a Liquidating Event, the
Partnership 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 Partners. No Partner shall take any action that is inconsistent
with, or not necessary to or appropriate for, the winding up of the
Partnership's business and affairs. The General Partner (or, if there is no
remaining General Partner, any Person elected by a majority in interest of the
Limited Partners (the "Liquidator")) shall be responsible for overseeing the
winding up and dissolution of the Partnership and shall take full account of the
Partnership's liabilities and property and the Partnership 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 General
Partner, include equity or other securities of the General Partner or any other
entity) shall be applied and distributed in the following order:

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

                           (2)      Second, to the payment and discharge of all
                                    of the Partnership's debts and liabilities
                                    to the General Partner;

                           (3)      Third, to the payment and discharge of all
                                    of the Partnership's debts and liabilities
                                    to the Limited Partners;

                           (4)      Fourth, to the holders of Partnership
                                    Interests that are entitled to any
                                    preference in distribution upon liquidation
                                    in accordance with the rights of any such
                                    class or series of Partnership Interests,
                                    including without limitation, Series A
                                    Preferred Units, Series B Preferred Units,
                                    and Series C 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 Partners in
                                    accordance with their Capital Accounts,
                                    after giving effect to all contributions,
                                    distributions, and allocations for all
                                    periods.

                  The General Partner shall not receive any additional
compensation for any services performed pursuant to this Article XIII.

                  B. Deferred Liquidation. Notwithstanding the provisions of
Section 13.2.A which require liquidation of the assets of the Partnership, but
subject to the order of priorities set forth therein, if prior to or upon
dissolution of the Partnership the Liquidator determines that an immediate sale
of part or all of the Partnership's assets would be impractical or would cause
undue loss to the Partners, 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 Partnership (including to those
Partners as

                                      -62-
<PAGE>   68

creditors) or distribute to the Partners, in lieu of cash, as tenants in common
and in accordance with the provisions of Section 13.2.A, undivided interests in
such Partnership 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
Partners, 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.

SECTION 13.3          COMPLIANCE WITH TIMING REQUIREMENTS OF REGULATIONS

                  If the Partnership is "liquidated" within the meaning of
Regulations Section 1.704-1(b)(2)(ii)(g), distributions shall be made under this
Article XIII to the General Partner and Limited Partners who have positive
Capital Accounts in compliance with Regulations Section 1.704-1(b)(2)(ii)(b)(2).
If any Partner 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 Partner shall
have no obligation to make any contribution to the capital of the Partnership
with respect to such deficit, and such deficit shall not be considered a debt
owed to the Partnership or to any other Person for any purpose whatsoever;
provided that a Protected Partner shall be obligated to make a contribution to
the Partnership with respect to such deficit balance in such Protected Partner's
Capital Account upon a liquidation of the Partnership to the extent of such
Protected Partner's Protected Amount; and provided further that the foregoing
shall not apply with respect to any other Partner to the extent, but only to
such extent, that such Partner has agreed in writing 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 Partnership (including, without
limitations, those Partners who have undertaken "deficit restoration
obligations" as defined in Exhibit E). In the discretion of the General Partner,
a pro rata portion of the distributions that would otherwise be made to the
General Partner and Limited Partners pursuant to this Article XIII may be: (A)
distributed to a trust established for the benefit of the General Partner and
Limited Partners for the purposes of liquidating Partnership assets, collecting
amounts owed to the Partnership and paying any contingent or unforeseen
liabilities or obligations of the Partnership or of the General Partner arising
out of or in connection with the Partnership (in which case the assets of any
such trust shall be distributed to the General Partner and Limited Partners from
time to time, in the reasonable discretion of the General Partner, in the same
proportions as the amount distributed to such trust by the Partnership would
otherwise have been distributed to the General Partner and Limited Partners
pursuant to this Agreement); or (B) withheld to provide a reasonable reserve for
Partnership liabilities (contingent or otherwise) and to reflect the unrealized
portion of any installment obligations owed to the Partnership, provided that
such withheld amounts shall be distributed to the General Partner and Limited
Partners as soon as practicable.

SECTION 13.4          RIGHTS OF LIMITED PARTNERS

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

SECTION 13.5          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 Partners pursuant
to Section 13.1, result in a dissolution of the Partnership, the General Partner
shall, within thirty (30) days thereafter, provide written notice thereof to
each of the Partners and to all other parties with whom the Partnership
regularly conducts business (as determined in the discretion of the General
Partner).

SECTION 13.6          CANCELLATION OF CERTIFICATE OF LIMITED PARTNERSHIP

                  Upon the completion of the liquidation of the Partnership cash
and property as provided in Section 13.2, the Partnership shall be terminated
and the Certificate and all qualifications of the Partnership as a foreign
limited partnership in jurisdictions other than the State of Delaware shall be
canceled and such other actions as may be necessary to terminate the Partnership
shall be taken.

SECTION 13.7          REASONABLE TIME FOR WINDING UP

                  A reasonable time shall be allowed for the orderly winding up
of the business and affairs of the Partnership and the liquidation of its assets
pursuant to Section 13.2, to minimize any losses otherwise attendant upon such
winding-up, and the provisions of this Agreement shall remain in effect among
the Partners during the period of liquidation.

SECTION 13.8          WAIVER OF PARTITION

                  Each Partner hereby waives any right to partition of the
Partnership property.

SECTION 13.9          LIABILITY OF LIQUIDATOR

                  The Liquidator shall be indemnified and held harmless by the
Partnership in the same manner and to the same degree as an Indemnitee may be
indemnified pursuant to Section 7.7.

                                   ARTICLE XIV
                  AMENDMENT OF PARTNERSHIP AGREEMENT; MEETINGS

SECTION 14.1          AMENDMENTS

                  A. General. Amendments to this Agreement may be proposed by
the General Partner or by any Limited Partners holding twenty-five percent (25%)
or more of the Partnership Interests. Following such proposal (except an
amendment pursuant to Section 14.1.B), the General Partner shall submit any
proposed amendment to the Limited Partners. The General Partner shall seek the
written vote of the Partners on the proposed amendment or shall call a meeting
to vote thereon and to transact any other business that it may deem appropriate.
For purposes of obtaining a written vote, the General Partner may require a
response within a reasonable specified time, but not less than fifteen (15)
days, and failure to respond in such time period shall constitute a vote which
is consistent with the General Partner's recommendation with respect to the
proposal. Except as provided in Section 14.1.B, 14.1.C or 14.1.D, a proposed
amendment shall be adopted and be effective as an amendment hereto if it is
approved by the General Partner and it receives the Consent of Partners holding
a majority of the Percentage Interests of the Limited Partners (including
Limited Partnership Interests held by the General Partner).

                  B. Amendments Not Requiring Limited Partner Approval.
Notwithstanding Section 14.1.A or 14.1.C, the General Partner shall have the
power, without the consent of the Limited Partners, to amend this Agreement as
may be required to facilitate or implement any of the following purposes:

                           (1)      to add to the obligations of the General
                                    Partner or surrender any right or power
                                    granted to the General Partner or any
                                    Affiliate of the General Partner for the
                                    benefit of the Limited Partners;

                           (2)      to reflect the admission, substitution,
                                    termination, or withdrawal of Partners in
                                    accordance with this Agreement (which may be
                                    effected through the replacement of Exhibit
                                    A with an amended Exhibit A);

                           (3)      to set forth the designations, rights,
                                    powers, duties, and preferences of the
                                    holders of any additional Partnership
                                    Interests issued pursuant to Article IV;

                           (4)      to reflect a change that does not adversely
                                    affect the Limited Partners in any material
                                    respect, or to cure any ambiguity, correct
                                    or supplement any provision in this
                                    Agreement not inconsistent with law or with
                                    other provisions of this Agreement, or make
                                    other changes with respect to matters
                                    arising under this Agreement that will not
                                    be inconsistent with law or with the
                                    provisions of this Agreement; and

                                      -65-
<PAGE>   71

                           (5)      to satisfy any requirements, conditions, or
                                    guidelines contained in any order,
                                    directive, opinion, ruling or regulation of
                                    a federal, state or local agency or
                                    contained in federal, state or local law.

                  The General Partner shall notify the Limited Partners when any
action under this Section 14.1.B is taken in the next regular communication to
the Limited Partners; provided, however, that no notice need be given of any
amendment of this Agreement to reflect the admission, substitution, termination,
or withdrawal of Partners in accordance with this Agreement (whether or not
effected through the replacement of Exhibit A with an amended Exhibit A). For
purposes of the immediately preceding sentence, notwithstanding any other means
by which the General Partner may provide any such notice to the Limited
Partners, such notice requirement shall be deemed to have been satisfied upon
the filing with the Securities and Exchange Commission by the Partnership of any
amendment to this Agreement permitted under this Section 14.1.B as an exhibit to
(i) a registration statement filed by the Partnership under the Securities Act
or (ii) any report or other document filed by the Partnership under the Exchange
Act.

                  C. Amendments Requiring Limited Partner Approval (Excluding
the General Partner). Notwithstanding Section 14.1.A, without the Consent of the
Outside Limited Partners, the General Partner shall not amend Section 4.2.A,
Section 5.1.E, Section 7.1.A (second sentence only), Section 7.5, Section 7.6,
Section 7.8, Section 7.11.B, Section 11.2, Section 13.1 (other than Section
13.1(iii) which can be amended only with a Consent of 90% of the Partnership
Units (including Partnership Units held by the General Partner)), the last
sentence of Section 11.4.A (provided that no such amendment shall in any event
adversely affect the rights of any lender who made a loan or who extended credit
and received in connection therewith a Pledge of Units prior to the date such
amendment is adopted unless, and only to the extent such lender consents
thereto), this Section 14.1.C or Section 14.2.

                  D. Other Amendments Requiring Certain Limited Partner
Approval. Notwithstanding anything in this Section 14.1 to the contrary, this
Agreement shall not be amended with respect to any Partner adversely affected
without the Consent of such Partner, or any Assignee who is a bona fide
financial institution that loans money or otherwise extends credit to a holder
of Units, adversely affected if such amendment would (i) convert a Limited
Partner's interest in the Partnership into a general partner's interest, (ii)
modify the limited liability of a Limited Partner, (iii) amend Section 7.11.A,
(iv) amend Article V or Article VI (except as permitted pursuant to Sections
4.2, 5.1.E, 5.4, 6.2 and 14.1(B)(3)), (v) amend Section 8.6 or any defined terms
set forth in Article I that relate to the Redemption Right (except as permitted
in Section 8.6.E), or (vi) amend Sections 11.3 or 11.5, or any additional
restrictions from Section 11.6.E or amend Sections 14.1.B(4) or 14.1.D. This
Section 14.1.D does not require unanimous consent of all Partners adversely
affected unless the amendment is to be effective against all Partners adversely
affected.

SECTION 14.2          MEETINGS OF THE PARTNERS

                  A. General. Meetings of the Partners may be called by the
General Partner and shall be called upon the receipt by the General Partner of a
written request by Limited Partners holding twenty-five percent (25%) or more of
the Partnership Interests. The call shall state the nature of the business to be
transacted. Notice of any such meeting shall be given to all Partners not less
than seven (7) days nor more than thirty (30) days prior to the date of such
meeting. Partners may vote in person or by proxy at such meeting. Whenever the
vote or Consent of Partners is permitted or required under this Agreement, such
vote or Consent may be given at a meeting of Partners or may be given in
accordance with the procedure prescribed in Section 14.1.A. Except as otherwise
expressly provided in this Agreement, the Consent of holders of a majority of
the Percentage Interests held by Limited Partners (including Limited Partnership
Interests held by the General Partner) shall control.

                  B. Actions Without a Meeting. Any action required or permitted
to be taken at a meeting of the Partners may be taken without a meeting if a
written consent setting forth the action so taken is signed by a majority of the
Percentage Interests of the Partners (or such other percentage as is expressly
required by this Agreement). Such consent may be in one instrument or in several
instruments, and shall have the same force and effect as a vote of a majority of
the Percentage Interests of the Partners (or such other percentage as is
expressly required by this Agreement). Such consent shall be filed with the
General Partner. An action so taken shall be deemed to have been taken at a
meeting held on the effective date so certified.

                  C. Proxy. Each Limited Partner may authorize any Person or
Persons to act for him by proxy on all matters in which a Limited Partner is
entitled to participate, including waiving notice of any meeting, or voting or
participating at a meeting. Every proxy must be signed by the Limited Partner or
its attorney-in-fact. No proxy shall be valid after the expiration of eleven
(11) months from the date thereof unless otherwise provided in the proxy. Every
proxy shall be revocable at the pleasure of the Limited Partner executing it,
such revocation to be effective upon the Partnership's receipt of written notice
thereof.

                  D. Conduct of Meeting. Each meeting of Partners shall be
conducted by the General Partner or such other Person as the General Partner may
appoint pursuant to such rules for the conduct of the meeting as the General
Partner or such other Person deem appropriate.

                                    determination of the rights, preferences and
                                    privileges of Partnership Interests; and

                           (2)      execute, swear to, acknowledge and file all

                                    appropriate or necessary, in the sole and
                                    absolute discretion of the General Partner
                                    or any Liquidator, to make, evidence, give,
                                    confirm or ratify any vote, consent,
                                    approval, agreement or other action which is
                                    made or given by the Partners hereunder or
                                    is consistent with the terms of this
                                    Agreement or appropriate or necessary, in
                                    the sole discretion of the General Partner
                                    or any Liquidator, to effectuate the terms
                                    or intent of this Agreement.

                  Nothing contained in this Section 15.11 shall be construed as
authorizing the General Partner or any Liquidator to amend this Agreement except
in accordance with Article XIV hereof or as may be otherwise expressly provided
for in this Agreement.

                  B. Irrevocable Nature. The foregoing power of attorney is
hereby declared to be irrevocable and a power coupled with an interest, in
recognition of the fact that each of the Partners will be relying upon the power
of the General Partner or any Liquidator to act as contemplated by this
Agreement in any filing or other action by it on behalf of the Partnership, and
it shall survive and not be affected by the subsequent Incapacity of any Limited
Partner or Assignee and the transfer of all or any portion of such Limited
Partner's or Assignee's Partnership Units and shall extend to such Limited
Partner's or Assignee's heirs, successors, assigns and personal representatives.
Each such Limited Partner or Assignee hereby agrees to be bound by any
representation made by the General Partner or any Liquidator, acting in good
faith pursuant to such power of attorney; and each such Limited Partner or
Assignee hereby waives any and all defenses which may be available to contest,
negate or disaffirm the action of the General Partner or any Liquidator, taken
in good faith under such power of attorney. Each Limited Partner or Assignee
shall execute and deliver to the General Partner or the Liquidator, within
fifteen (15) days after receipt of the General Partner's or Liquidator's request
therefor, such further designation, powers of attorney and other instruments as
the General Partner or the Liquidator, as the case may be, deems necessary to
effectuate this Agreement and the purposes of the Partnership.

SECTION 15.12         ENTIRE AGREEMENT

                  This Agreement contains the entire understanding and agreement
among the Partners with respect to the subject matter hereof and supersedes any
prior written oral understandings or agreements among them with respect thereto.

SECTION 15.13         NO RIGHTS AS SHAREHOLDERS

                  Nothing contained in this Agreement shall be construed as
conferring upon the holders of the Partnership Units any rights whatsoever as
shareholders of the General

                                      -70-

Partner, including, without limitation, any right to receive dividends or other
distributions made to shareholders of the General Partner or to vote or to
consent or receive notice as shareholders in respect to any meeting of
shareholders for the election of trustees of the General Partner or any other
matter.

SECTION 15.14         LIMITATION TO PRESERVE REIT STATUS

                  To the extent that any amount paid or credited to the General
Partner or any of its officers, trustees, employees or agents pursuant to
Section 7.4 or Section 7.7 would constitute gross income to the General Partner
for purposes of Section 856(c)(2) or 856(c)(3) of the Code (a "General Partner
Payment") then, notwithstanding any other provision of this Agreement, the
amount of such General Partner Payment for any fiscal year shall not exceed the
lesser of:

                           (i) an amount equal to the excess, if any, of (a)
4.20% of the General Partner's total gross income (but not including the amount
of any General Partner Payments) for the fiscal year which is described in
subsections (A) though (H) of Section 856(c)(2) of the Code over (b) the amount
of gross income (within the meaning of Section 856(c)(2) of the Code) derived by
the General Partner from sources other than those described in subsections (A)
through (H) of Section 856(c)(2) of the Code (but not including the amount of
any General Partner Payments); or

                           (ii) an amount equal to the excess, if any of (a) 25%
of the General Partner's total gross income (but not including the amount of any
General Partner Payments) for the fiscal year which is described in subsections
(A) through (I) of Section 856(c)(3) of the Code over (b) the amount of gross
income (within the meaning of Section 856(c)(3) of the Code) derived by the
General Partner from sources other than those described in subsections (A)
through (I) of Section 856(c)(3) of the Code (but not including the amount of
any General Partner Payments); provided, however, that General Partner Payments
in excess of the amounts set forth in subparagraphs (i) and (ii) above may be
made if the General Partner, as a condition precedent, obtains an opinion of tax
counsel that the receipt of such excess amounts would not adversely affect the
General Partner's ability to qualify as a REIT. To the extent General Partner
Payments may not be made in a year due to the foregoing limitations, such
General Partner Payments shall carry over and be treated as arising in the
following year, provided, however, that such amounts shall not carry over for
more than five years, and if not paid within such five year period, shall
expire; provided further, that (i) as General Partner Payments are made, such
payments shall be applied first to carry over amounts outstanding, if any, and
(ii) with respect to carry over amounts for more than one Partnership Year, such
payments shall be applied to the earliest Partnership Year first.

                           1.704-1(b)(2)(iv)(m), the computation of all items of
                           income, gain, loss and deduction shall be made
                           without regard to any election under Section 754 of
                           the Code which may be made by the Partnership,
                           provided that the amounts of any adjustments to the
                           adjusted bases of the assets of the Partnership made
                           pursuant to Section 734 of the Code as a result of
                           the distribution of property by the Partnership to a
                           Partner (to the extent that such adjustments have not
                           previously been reflected in the Partners' Capital
                           Accounts) shall be reflected in the Capital Accounts
                           of the Partners in the manner and subject to the
                           limitations prescribed in Regulations Section
                           l.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)(l)(B) or
                           705(a)(2)(B) of the Code are not includible 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 Partnership property shall be
                           determined as if the adjusted basis of such property
                           as of such date of disposition were equal in amount
                           to

                           property as of such date.

                  (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 Partnership
                           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 C to the Agreement hereof shall not be taken
                           into account.

         C.       A transferee (including any Assignee) of a Partnership 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 Partnership assets
                           shall be adjusted upward or downward to reflect any
                           Unrealized Gain or Unrealized Loss attributable to
                           such Partnership 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 6.1 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 Partnership by any new or
                           existing Partner in exchange for more than a de
                           minimis Capital Contribution; (b) immediately prior
                           to the distribution by the Partnership to a Partner
                           of more than a de minimis amount of property as
                           consideration for an interest in the Partnership; and
                           (c) immediately prior to the liquidation of the
                           Partnership within the meaning of Regulations Section
                           1.704-l(b)(2)(ii)(g), provided, however, that
                           adjustments pursuant to clauses (a) and (b) above
                           shall be made only if the General Partner determines
                           that such adjustments are necessary or appropriate to
                           reflect the relative economic interests of the
                           Partners in the Partnership.

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

                  (4)      In determining Unrealized Gain or Unrealized Loss for
                           purposes of this Exhibit B, the aggregate cash amount
                           and fair market value of all Partnership assets
                           (including cash or cash equivalents) shall be
                           determined by the General Partner using such
                           reasonable method of valuation as it may adopt, or in
                           the case of a liquidating distribution pursuant to
                           Article XIII of the Agreement, shall be determined
                           and allocated by the Liquidator using such reasonable
                           methods of valuation as it may adopt. The General
                           Partner, or the Liquidator, as the case may be, shall
                           allocate such aggregate fair market value among the
                           assets of the Partnership 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 B 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 General Partner 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
Partnership, the General Partner, or the Limited Partners) are computed in order
to comply with such Regulations, the General Partner may make such modification
without regard to Article XIV of the Agreement, provided that it is not likely
to have a material effect on the amounts distributable to any Person pursuant to
Article XIII of the Agreement upon the dissolution of the Partnership. The
General Partner also shall (i) make any adjustments that are necessary or
appropriate to maintain equality between the Capital Accounts of the Partners
and the amount of Partnership capital reflected on the Partnership's balance
sheet, as computed for book purposes, in accordance with Regulations Section
l.704-l(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 Partnership on Capital Contributions
or on balances in Partners' Capital Accounts.

3.       No Withdrawal

         No Partner shall be entitled to withdraw any part of its Capital
Contribution or Capital Account or to receive any distribution from the
Partnership, except as provided in Articles IV, V, VII and XIII of the
Agreement.

                                    EXHIBIT C

                            SPECIAL ALLOCATION RULES

1.                Special Allocation Rules.

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

                  A.       Minimum Gain Chargeback. Notwithstanding the
provisions of Section 6.1 of the Agreement or any other provisions of this
Exhibit C, if there is a net decrease in Partnership Minimum Gain during any
Partnership Year, each Partner shall be specially allocated items of Partnership
income and gain for such year (and, if necessary, subsequent years) in an amount
equal to such Partner's share of the net decrease in Partnership 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 Partner 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 Partner's Adjusted Capital Account Deficit shall be determined prior to any
other allocations pursuant to Section 6.1 of this Agreement with respect to such
Partnership Year and without regard to any decrease in Partner Minimum Gain
during such Partnership Year.

                  B.       Partner Minimum Gain Chargeback. Notwithstanding any
other provision of Section 6.1 of this Agreement or any other provisions of this
Exhibit C (except Section 1.A hereof), if there is a net decrease in Partner
Minimum Gain attributable to a Partner Nonrecourse Debt during any Partnership
Year, each Partner who has a share of the Partner Minimum Gain attributable to
such Partner Nonrecourse Debt, determined in accordance with Regulations Section
1.704-2(i)(5), shall be specially allocated items of Partnership income and gain
for such year (and, if necessary, subsequent years) in an amount equal to such
Partner's share of the net decrease in Partner Minimum Gain attributable to such
Partner 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 General
Partner and Limited Partner 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 Partner's Adjusted Capital Account
Deficit shall be determined prior to any other allocations pursuant to Section
6.1 of the Agreement or this Exhibit with respect to such Partnership Year,
other than allocations pursuant to Section 1.A hereof.

                  C.       Qualified Income Offset. In the event any Partner
unexpectedly receives any adjustments, allocations or distributions described in
Regulations Sections 1.704-l(b)(2)(ii)(d)(4), l.704-1(b)(2)(ii)(d)(5), or
1.704-l(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 Partnership Year, such
Partner has an Adjusted Capital Account Deficit, items of


<PAGE>   85

Partnership income and gain (consisting of a pro rata portion of each item of
Partnership income, including gross income and gain for the Partnership Year)
shall be specifically allocated to such Partner 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
Partner has an Adjusted Capital Account Deficit at the end of any Partnership
Year (after taking into account allocations to be made under the preceding
paragraphs hereof with respect to such Partnership Year), each such Partner
shall be specially allocated items of Partnership income and gain (consisting of
a pro rata portion of each item of Partnership income, including gross income
and gain for the Partnership 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 Partnership Year shall be allocated to the Partners in accordance with their
respective Percentage Interests. If the General Partner determines in its good
faith discretion that the Partnership'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 General Partner is authorized,
upon notice to the Limited Partners, to revise the prescribed ratio for such
Partnership Year to the numerically closest ratio which would satisfy such
requirements.

                  F.       Partner Nonrecourse Deductions. Any Partner
Nonrecourse Deductions for any Partnership Year shall be specially allocated to
the Partner who bears the economic risk of loss with respect to the Partner
Nonrecourse Debt to which such Partner 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 Partnership asset pursuant to
Section 734(b) or 743(b) of the Code is required, pursuant to Regulations
Section 1.704-l(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 Partners in a manner consistent Exhibit E-1 with 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 Partners in the same manner as its correlative item of
"book" income, gain, loss or

                                      C-2
<PAGE>   86

deduction is allocated pursuant to Section 6.1 of the Agreement and Section 1 of
this Exhibit C.

                  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 Partners as follows:

                           (1)      (a)      In the case of a Contributed
                                    Property, such items attributable thereto
                                    shall be allocated among the Partners
                                    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 C); and

                                    (b)      any item of Residual Gain or
                                    Residual Loss attributable to a Contributed
                                    Property shall be allocated among the
                                    Partners in the same manner as its
                                    correlative item of "book" gain or loss is
                                    allocated pursuant to Section 6.1 of the
                                    Agreement and Section 1 of this Exhibit C.

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

                                             (i)      first, be allocated among
                                    the Partners 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 B;

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

                                    (b)      any item of Residual Gain or
                                    Residual Loss attributable to an Adjusted
                                    Property shall be allocated among the
                                    Partners in the same manner its correlative
                                    item of "book" gain or loss is allocated
                                    pursuant to Section 6.1 of the Agreement and
                                    Section 1 of this Exhibit C.

                           (3)      all other items of income, gain, loss and

                                    correlative item of "book" gain or loss is
                                    allocated pursuant to Section 6.1 of the
                                    Agreement and Section 1 of this Exhibit C.

                  C.       To the extent 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 General Partner shall, subject to the following, have the
authority to elect the method to be used by the Partnership and such election
shall be binding on all Partners; provided that, to the extent that the General
Partner has agreed to use a particular method with respect to a

                                 (CAP AGREEMENT)

                  BACKGROUND

                  On September 2, 1997, pursuant to a closing under that certain
Agreement for Contribution of Real Estate and Related Property dated as of
August 1, 1997, by and among the Partnership, the General Partner, Columbus
America Properties, L.L.C. ("CAP"), and certain members of CAP (the
"Contribution Agreement"), CAP received 1,690,000 Class A Units, subject to
adjustment as provided in the Contribution Agreement, (referred to as the "CAP
Units"), in exchange for the office properties known as Texaco Center, LL&E
Tower and 601 Tchoupitoulas Garage (collectively, the "CAP Properties"). In
connection with the issuance of the CAP Units, the First Prior Amendment to the
Original Partnership Agreement was executed, which set forth specific agreements
regarding certain additional rights and obligations of CAP and which was later
amended by the Sixth Prior Amendment to the Original Partnership Agreement. Such
specific agreements are described below.

                  All capitalized terms used in this Exhibit E-1 and not
otherwise defined have the meanings assigned in the Agreement.

SPECIFIC AGREEMENTS

                  1.       Notwithstanding any other provision in the Agreement
to the contrary and in addition to (and not in lieu thereof) any and all other
rights of CAP under the Agreement:

                           (i)      The holders of the CAP Units shall have the
right at any time and from time to time, to exchange all or any number of such
CAP Units at the request of such holder for Shares in the form required in
Section 8.6.B(i) of the Agreement, but subject in all respects to the terms of a
certain Registration Rights Agreement dated as of September 2, 1997, by and
among the General Partner, CAP and the other signatories thereto; and

                           (ii)     CAP shall have the right, exercisable upon
written notice to Partnership at any time and from time to time before the
earlier to occur of (a) September 3, 2000, or (b) the date that CAP shall have
either transferred or converted all of its CAP Units into Shares, to require the
Partnership or the General Partner to acquire all, or any portion or portions,
of the CAP Units at $29.00 per CAP Unit. The price for such CAP Units shall be
paid by the Partnership or the General Partner in immediately available funds
not less than five (5) days after receipt of such notice from CAP. The CAP Units
shall be conveyed to the Partnership or the General Partner, as applicable, free
and clear of all liens and encumbrances, other than those liens and
encumbrances, if any, in favor of General Partner or Partnership. At the closing
of the acquisition of the CAP Units by the Partnership or the General Partner,
the parties shall execute instruments of assignment and conveyance in the form
attached to the First Prior Amendment at "Exhibit B" and an amendment to the
Agreement evidencing the assignment of the CAP Units to the


<PAGE>   91

Partnership, or the General Partner, as applicable, and the withdrawal of CAP as
a Limited Partner of the Partnership.

                  2.       Notwithstanding any other provision of the First
Prior Amendment (as amended by the Sixth Prior Amendment) or the Agreement to
the contrary, upon liquidation of the Partnership, CAP shall be required to
contribute to the Partnership the deficit balance in its Capital Account
computed in accordance with Section 1.752-2(b)(1) and (2) of the Regulations,
provided, however, that such contribution obligation shall not exceed
$84,350,000 (the "Deficit Obligation"). CAP specifically waives any right of
contribution or subrogation with respect to such Deficit Obligation and neither
the General Partner nor any other Partner or other Person shall be required to
reimburse CAP for such contribution. Irrespective of the balance in the Capital
Account of CAP, CAP agrees to indemnify the Partnership and the General Partner
to the extent that the recourse obligations of the Partnership exceed the assets
of the Partnership available to satisfy such recourse obligations. This
indemnity obligation is intended to protect and hold the Partnership and the
General Partner harmless for such recourse obligations without regard to
obligations imposed on the General Partner under applicable state law or other
contract provisions. This indemnity obligation shall be limited to $84,350,000
(the "Indemnity Obligation"). CAP hereby specifically waives any right of
contribution from or subrogation against the General Partner or any other
Partner and neither the Partnership nor any other Partner shall be required to
contribute to or otherwise reimburse CAP with respect to such indemnity. Upon
payment of such indemnity, CAP's Capital Account shall be credited with such
payment only to the extent of any deficit in such Capital Account. Amounts paid
to the Partnership pursuant to the Deficit Obligation or the Indemnity
Obligation shall be used to satisfy the recourse obligations of the Partnership.

                  CAP's Deficit Obligation and Indemnity Obligation shall not in
the aggregate exceed $84,350,000 (subject to reduction as provided herein). In
addition, the Deficit Obligation and the Indemnity Obligation shall be forever
reduced to $6,350,000 immediately upon the first placing, after acquisition of
the CAP Properties by the Partnership, of a non-recourse third party mortgage on
the CAP Properties securing a third party non-recourse loan to the Partnership
in an amount not less than $78,000,000.

                  Upon the sale, redemption, conversion or other disposition of
the CAP Units, the Deficit Obligation and the Indemnity Obligation of CAP under
this provision shall terminate proportionately with the number of CAP Units
sold, redeemed, converted or otherwise disposed of; provided, however, that a
transferee of CAP may, in its sole discretion, assume the Deficit Obligation
and/or the Indemnity Obligation of CAP and, in such event, the Deficit
Obligation and the Indemnity Obligation shall be the obligations solely of such
transferee (but CAP's obligation shall in all events be proportionately
terminated as of the date of any such disposition of its interest in the
Partnership). Nothing in this paragraph 2 shall in any way affect the sale,
exchange, or conversion rights of CAP under the Agreement or under the First and
Sixth Prior Amendments.

                                (1120 AGREEMENT)

                  BACKGROUND

                  On October 16, 1997, pursuant to a closing under that certain
Contribution Agreement dated September 4, 1997, as amended, by and between the
Partnership and 1120 20th Street Associates ("1120") (the "Contribution
Agreement"), 1120 received 1,645,885 Class A Units, subject to adjustment as
provided in the Contribution Agreement, (referred to as the "1120 Units") in
exchange for the office property known as One Lafayette Centre, 1120 20th
Street, N.W., Washington, D.C. (the "1120 Property"). In connection with the
issuance of the 1120 Units, the Second Prior Amendment to the Original
Partnership Agreement, which set forth specific agreements regarding certain
additional rights and obligations of 1120, was executed. Such specific
agreements are described below.

                  All capitalized terms used in this Exhibit E-2 and not
otherwise defined herein have the meanings assigned in the Agreement.

                  SPECIFIC AGREEMENTS

                  Notwithstanding any other provision of the Agreement to the
contrary, upon liquidation of the Partnership, 1120 shall be required to
contribute to the Partnership the deficit balance in its Capital Account
computed in accordance with Sections 1.752-2(b)(1) and (2) of the Regulations;
provided, however, that such contribution obligation shall not exceed
$14,000,000 (the "Deficit Obligation"). 1120 specifically waives any right of
contribution or subrogation with respect to such Deficit Obligation and neither
the General Partner nor any other Partner or other Person shall be required to
reimburse 1120 for such contribution. Irrespective of the balance in the Capital
Account of 1120, 1120 agrees to indemnify the Partnership and the General
Partner to the extent that the recourse obligations of the Partnership exceed
the assets of the Partnership available to satisfy such recourse obligations.
This indemnity obligation is intended to protect and hold the Partnership and
the General Partner harmless for such recourse obligations without regard to
obligations imposed on the General Partner under applicable state law or other
contract provisions. This indemnity obligation shall be limited to $14,000,000
(the "Indemnity Obligation"). 1120 specifically waives any right of contribution
from or subrogation against the General Partner or any other Partner and neither
the Partnership nor any other Partner shall be required to contribute to or
otherwise reimburse 1120 with respect to such indemnity. Upon payment of such
indemnity, 1120's Capital Amount shall be credited with such payment only to the
extent of any deficit in such Capital Account. Amounts paid to the Partnership
pursuant to the Deficit Obligation or the Indemnity Obligation shall be used to
satisfy the recourse obligations of the Partnership.

                  Upon the sale, redemption, conversion or other disposition of
the 1120 Units, the Deficit Obligation and the Indemnity Obligation of 1120
under this provision shall terminate; provided, however, a transferee of 1120
may, in its sole discretion, assume the Deficit Obligation and/or the Indemnity
Obligation of 1120 and, in such event, the Deficit


<PAGE>   93

Obligation and the Indemnity Obligation shall be the obligation solely of such
transferee (but 1120's obligation shall in all events be terminated as of the
date of any disposition of its interest in the Partnership). Nothing herein
shall in any way effect the sale, exchange or conversion rights of 1120 under
the Agreement or under the Second Prior Amendment.

                           (WRIGHT RUNSTAD AGREEMENT)

BACKGROUND

                  On December 16, 1997, (i) pursuant to a closing under that
certain Contribution Agreement dated December 16, 1997, by and between the
Partnership, WRAM (as defined below), WRH (as defined below) and certain other
parties (the "Contribution Agreement") (a) Wright Runstad Asset Management L.P.,
a Washington limited partnership ("WRAM"), received 446,890 Class B Units in
exchange for certain partnership interests ("Titleholder Interests") in Wright
Runstad Properties L.P., a Delaware limited partnership (the "Titleholder") and
(b) Wright Runstad Holdings L.P., a Washington limited partnership ("WRH"),
received 2,168,810 Class B Units in exchange for certain Titleholder Interests;
and (ii) pursuant to a closing under that certain Investment Agreement dated
December 16, 1997, by and among the Partnership, Wright Runstad Associates
Limited Partnership, a Washington limited partnership, ("WRALP"), H. Jon Runstad
("Runstad"), Douglas E. Norberg ("Norberg"), John F. Nordby ("Nordby"), and
certain other parties (the "Investment Agreement"), Runstad, Norberg, and Nordby
received, in the aggregate, 137,427 Class B Units in exchange for certain
limited partnership interests in WRALP ("WRALP Interests"). WRAM and WRH are
collectively referred to herein as the "Contributors." Runstad, Norberg, Nordby
are collectively referred to herein as the "Principals." The Class B Units
issued as described above are referred to herein as the WRP Units. Certain
property owned by the Titleholder as described in the Contribution Agreement is
referred to herein as the "WRP Property." In connection with the issuance of the
WRP Units, the Third Prior Amendment to the Original Partnership Agreement,
which set forth specific agreements regarding certain additional rights and
obligations of the Contributors and the Principals, was executed. Such specific
agreements are described below.

                  All capitalized terms used in this Exhibit E-3 and not
otherwise defined shall have the meanings assigned to them in the Agreement.

SPECIFIC AGREEMENTS

                  1.       Right to Assign. Notwithstanding any other provision
of this Agreement or of the Third Prior Amendment, each Contributor shall have
the right to assign all or any portion of its WRP Units, together with any and
all other rights of such Contributor pursuant to the Third Prior Amendment and
the Agreement, to one or more of the constituent partners or shareholders,
members, partners, or beneficiaries of constituent partners of such Contributor
on December 16, 1997, without the need for the consent of the General Partner or
any Limited Partner and without being subject to the right of first refusal set
forth in Section 11.3.A(a) of the Agreement, but in each case subject to the
restrictions and conditions set forth in Sections 11.3.C, 11.3.D, 11.3.E, 11.6.E
and 11.6.F of the Agreement. Upon the delivery of written notice of such an
assignment to the General Partner, each assignee of WRP Units pursuant to the
immediately preceding sentence shall be admitted to the Partnership as a
Substituted Limited Partner owning the WRP Units so assigned and having all of
the rights of a Limited Partner under the


<PAGE>   95

Agreement and the Third Prior Amendment, subject only to such assignee executing
and delivering to the Partnership an acceptance of all of the terms and
conditions of the Agreement and such other documents or instruments as the
General Partner may reasonably require to effect such admission, in accordance
with Section 11.4.B of the Agreement. Each permitted assignee of any of the WRP
Units issued to a Contributor pursuant to the Contribution Agreement that is
admitted as a Substituted Limited Partner in accordance with this Section 1 or
Article XI of the Agreement, for so long as such Person owns any such WRP Units,
is referred to herein as a "Contributor Limited Partner." Upon satisfaction of
the condition described in the second sentence of this Section 1, the General
Partner shall amend Exhibit A to the Agreement in the manner described in
Section 11.4.C of the Agreement. For purposes of Section 8.6 of the Agreement,
each Contributor Limited Partner which is a permitted assignee of a Contributor
shall be entitled to exercise its right to require the Partnership to redeem all
or any portion of the WRP Units assigned to it by such Contributor at any time.

                  2.       Adjustments to Carrying Values.

                           (a)      Upon the admission of the Contributors and
         the Principals to the Partnership and upon the distribution by the
         Partnership of the Cash Amount to either Contributor or to any
         Principal or any Contributor Limited Partner pursuant to the exercise
         of the Redemption Right with respect to the WRP Units held by such
         Contributor, Principal or Contributor Limited Partner, the Carrying
         Values of the Assets of the Partnership shall be adjusted in accordance
         with the procedures described in Section 1.D of Exhibit B to the
         Agreement; provided, however, that in order to minimize the
         administrative burden associated with the adjustments required by this
         Section 2(a) in connection with the distribution of the Cash Amount to
         a Contributor, a Principal or a Contributor Limited Partner, the
         Partnership shall make the adjustments to the Carrying Values of the
         Partnership's Assets (and the resulting adjustments to the Capital
         Accounts of the Partners) only upon the happening of the most material
         event during the calendar year that is described in Section 1.D(2) of
         Exhibit B to the Agreement (the "Annual Adjustment"); and provided,
         further, that upon the distribution of the Cash Amount to a
         Contributor, a Principal or a Contributor Limited Partner or, at the
         option of the General Partner, upon the occurrence of any other event
         described in Section 1.D(2) of Exhibit B to the Agreement, that occurs
         during any year other than as of the date of the Annual Adjustment, the
         Partnership shall, at the time of such distribution, make adjustments
         to the Carrying Values of the Partnership's Assets in accordance with
         the procedures described in Section 1.D of Exhibit B to the Agreement
         for purposes of adjusting the Capital Account of such Contributor, such
         Principal or such Contributor Limited Partner who has exercised his
         Redemption Right or such other affected Partner, but no such
         adjustments shall be necessary at such time with respect to the Capital
         Account balances of Partners who remain Partners through the date of
         the Annual Adjustment or are otherwise not directly affected by any
         such other event.

                           (b)      Any determination of the fair market value
         of Partnership assets pursuant to Section 1.D of Exhibit B to the
         Agreement (for purposes of calculating Unrealized Gain or Unrealized
         Loss), with respect to adjusting the

                                    E-3 - 2
<PAGE>   96

         Carrying Values of Partnership assets in connection with the exercise
         of Redemption Rights by a Contributor, any Principal or any Contributor
         Limited Partner shall be made by assuming that the aggregate fair
         market value of all Partnership assets is equal to the aggregate Cash
         Amount that would be distributed by the Partnership if all Partnership
         Units held by all Partners (including the General Partner) were
         redeemed in exchange for the Cash Amount with respect to each such
         Partnership Unit at such time, provided, however, such valuation
         methodology shall not be utilized for purposes of determining the fair
         market value of the Partnership's assets with respect to any such
         exercise of Redemption Rights in contemplation of an assignment by or
         reorganization of the Partnership for the benefit of creditors and any
         liquidation of the Partnership related thereto or following the filing
         by (or in contemplation of a filing) by the Partnership of a case under
         Title 11 of the U.S. Code.

                  3.       Allocations. Notwithstanding the provisions of
Section 2.C of Exhibit C to the Agreement, for purposes of allocating items of
income, gain, loss and deduction with respect to the WRP Property in the manner
required by Section 704(c) of the Code, the Partnership shall employ, and shall
cause any entity controlled by the Partnership which holds title to any of the
WRP Property to employ, the "traditional method" as set forth in Regulation
Section 1.704-3(b).

                  4.       Obligation to Restore Deficit Capital Account.

                           (a)      For purposes of this Section 4, the
         following terms shall have the meanings set forth below:

                                    (i)      "DRO Amount" means (A) with respect
                  to WRAM, $10,873,678, (B) with respect to WRH, $63,014,285 and
                  (C) with respect to each Scheduled Assignee, the amount set
                  forth opposite such Scheduled Assignee's name on Schedule 1
                  hereto.

                                    (ii)     "Partner Contribution Agreement"
                  means one or more agreements in favor of that certain
                  partnership or those certain partnerships that are partners in
                  WRH, which were executed concurrently with the Third Prior
                  Amendment and have been assigned by such partnerships to WRH,
                  pursuant to which a Second-Tier Partner has agreed to make
                  certain capital contributions to WRH on the terms and subject
                  to the conditions set forth in such Partner Contribution
                  Agreement.

                                    (iii)    "Partner Contribution Amount"

                  in WRH and who have executed and delivered one or more Partner
                  Contribution Agreements.

                           (b)      Notwithstanding any other provisions of the
         Agreement, upon liquidation of the Partnership or upon the liquidation
         of the Partnership Interest of a Contributor or a Scheduled Assignee,
         each Contributor or Scheduled Assignee whose interest is being
         liquidated shall contribute to the Partnership, in accordance with
         Section 1.704-1(b)(2)(ii)(b)(2) of the Regulations, the deficit
         balance, if any, in its Capital Account, calculated after the
         allocation for such year of all items of Net Income, Net Losses, Gross
         Income and Unrealized Gain or Unrealized Loss allocated in accordance
         with Section 1.D of Exhibit B to the Agreement; provided, however, that
         in no event shall such contribution obligation for any Contributor or
         Scheduled Assignee exceed such Contributor's or Scheduled Assignee's
         DRO Amount. In addition, WRH assigned and conveyed to the Partnership,
         effective upon distribution of the WRP Units by WRH, all of WRH's
         rights under each Partner Contribution Agreement provided by a
         Second-Tier Partner; provided that in no event shall the contribution
         obligation pursuant to such Partner Contribution Agreement exceed such
         Second-Tier Partner's Partner Contribution Amount. The obligation
         pursuant to this Section 4(b) shall be for the benefit of the
         Partnership, the General Partner, the creditors of the Partnership or
         any other person to whom any debts, liabilities or obligations are owed
         by (or who otherwise has any claim against) the Partnership or the
         General Partner in its capacity as the general partner of the
         Partnership and shall be enforceable by such parties. Each Contributor
         and Scheduled Assignee unconditionally and irrevocably waives any
         subrogation, reimbursement or similar rights to which it might
         otherwise be entitled as the result of its performance with respect to
         the obligation created pursuant to Section 4(b), whether such rights
         arise with respect to the Partnership, another Partner, or a third
         party; provided, however, that the General Partner shall in all events
         be entitled to enforce the contribution obligation of a Contributor or
         Scheduled Assignee undertaken pursuant to Section 4(b).

                           (c)      Notwithstanding the foregoing, in the event
         that the General Partner, pursuant to Section 8.6.B of the Agreement,
         elects to assume directly and satisfy a Redemption Right exercised by a
         Contributor or a Scheduled Assignee (a "Tendering Limited Partner"),
         the General Partner shall assume the obligation of the Tendering
         Limited Partner pursuant to Section 4(b) above with respect to the WRP
         Units transferred to the General Partner by such Tendering Limited
         Partner; provided, however, that if the adjustment to the Carrying
         Values of Partnership Assets and the related adjustments to the Capital
         Accounts of the Partners pursuant to Section 2 hereof and Section 1.D
         of Exhibit B to the Agreement that would have been undertaken pursuant
         to Section 2 hereof had the Partnership satisfied the Redemption Right
         exercised by such Tendering Limited Partner would have resulted in the
         Capital Account of the Tendering Limited

                                    E-3 - 4
<PAGE>   98

         Partner having a zero or positive balance, then, with respect to such
         WRP Units acquired from the Tendering Limited Partner, the General
         Partner shall have no obligation pursuant to Section 4(b) hereof with
         respect to a liquidation of the Partnership or a liquidation of the
         Partnership Interest reflected by such WRP Units that occurs more than
         twelve months following the acquisition of such WRP Units by the
         General Partner.

                           (d)      In the event that the liquidation of the
         Partnership Interest of a Tendering Limited Partner, other than in
         connection with the liquidation of the Partnership, would trigger an
         obligation pursuant to Section 4(b) hereof to contribute an amount to
         the Partnership, then the Net Income of the Partnership for the portion
         of such year ending on the Specified Redemption Date with respect to
         such Tendering Limited Partner shall be specially allocated to such
         Tendering Limited Partner in the amount necessary to eliminate the
         deficit balance in its Capital Account remaining after all other
         adjustments for such year (including any adjustments made pursuant to
         Section 1.D of Exhibit B to the Agreement).

                  5.       Maintenance of Recourse Debt. The Partnership shall
maintain unsecured liabilities as to which the creditor has recourse to the
General Partner, including any such unsecured recourse liabilities (as to which
the creditor has recourse to the General Partner in its capacity as General
Partner) of any other entity that is allocable to the Partnership, in an
aggregate amount not less than the amount necessary such that: (a) prior to the
distribution by WRAM and WRH of WRP Units issued to them pursuant to the
Contribution Agreement, the amount of Partnership recourse liabilities allocated
to each of WRAM and WRH shall be not less than its DRO Amount; and (b) following
the distribution by WRAM and WRH of WRP Units issued to them pursuant to the
Contribution Agreement, the amount of Partnership recourse liabilities allocated
directly or indirectly to all Scheduled Assignees and Second-Tier Partners shall
be not less than the sum of their respective DRO Amounts and Partner
Contribution Amounts. In making such determination, the Partnership shall take
into account any and all allocations of Partnership recourse liabilities to
other Partners by reason of any guarantees, indemnities, restoration obligations
or other, similar arrangements with respect to any such Partners, and the
liability by reason of any such Partner's status as a general partner of the
Partnership.

                  6.       Amendments. Notwithstanding any provision in the
Agreement to the contrary, the provisions hereof and of the Third Prior
Amendment may be waived or amended or otherwise modified with the prior written
consent of holders of more than fifty percent (50%) of the WRP Units at the time
outstanding and without the consent of any other Limited Partner.

                                   EXHIBIT E-4

                              (GALBREATH AGREEMENT)

                  BACKGROUND

                  On April 21, 1998, Galbreath-Denver Limited Partnership, an
Ohio limited partnership ("Galbreath") and 1560 Broadway Partnership, a Colorado
general partnership ("Broadway") (collectively the "Additional Limited
Partners") each was issued 1,684 Class B Units (referred to as the "Galbreath
and Broadway Units"). In connection with the issuance of the Galbreath and
Broadway Units, a Prior Addendum dated as of April 21, 1998, to the Original
Partnership Agreement, which set forth specific agreements regarding certain
additional rights and obligations of the Additional Limited Partners, was
executed. Such specific agreements are described below.

                  All capitalized terms used in this Exhibit E-4 and not
otherwise defined shall have the meanings assigned in the Agreement.

                  SPECIFIC AGREEMENTS

                  Notwithstanding any other provision of the Agreement to the
contrary, upon liquidation of the Partnership, each of the Additional Partners
shall be required to contribute to the Partnership the deficit balance in such
party's Capital Account computed in accordance with Sections 1.752-2(b)(1) and
(2) of the Regulations; provided, however, that such contribution obligation
shall not exceed the amount by which the recourse obligations of the Partnership
exceed the assets of the Partnership available to satisfy such recourse
obligations and shall not exceed $4,154,000 with respect to Galbreath and the
lesser of the deficit balance in Broadway's Capital Account in "owner" at the
date of "closing" reduced by any income allocated to Broadway after the date of
Closing or $10,500,000 with respect to Broadway (collectively, the "Deficit
Obligation"). Each of the Additional Limited Partners specifically waives any
right of contribution or subrogation with respect to such Deficit Obligation and
neither the General Partner nor any other Partner or other Person shall be
required to reimburse the Additional Limited Partners for such contributions.
Upon payment of such Deficit Obligation, each Additional Limited Partner's
Capital Account shall be credited with such payment. Amounts paid to the
Partnership pursuant to the Deficit Obligation shall be used to satisfy the
recourse obligations of the Partnership.

                  Upon the sale, redemption, conversion or other disposition of
the Galbreath and Broadway Units received by any Additional Limited Partner, the
Deficit Obligation of such Additional Limited Partner shall be reduced in an
amount equal to the percentage of the Galbreath and Broadway Units owned by such
Additional Limited Partner which were sold, redeemed, converted or otherwise
disposed of by such Additional Limited Partner, and upon the sale, redemption,
conversion or other disposition of all the Galbreath and Broadway Units received
by any Additional Limited Partner, the Deficit Obligation shall be terminated
with respect to such Additional Limited Partner. Nothing in this Exhibit E-4


<PAGE>   100

shall in any way effect the sale, exchange or conversion rights of the
Additional Limited Partners under the Agreement or this Exhibit E-4.

                  In the case of Galbreath only, certain partners of Galbreath
shall execute and deliver to the Partnership, and the Partnership shall accept,
a Guarantee in the form agreed to by such Galbreath partners and the
Partnership.

                                   EXHIBIT E-5

                          (PALO ALTO SQUARE AGREEMENT)

                  BACKGROUND

                  Pursuant to a closing under that certain Contribution
Agreement dated September 28, 1999, by and between Palo Alto Square Limited
Partnership, an Illinois limited partnership, ("Contributor") and the General
Partner (the "Contribution Agreement"), Contributor was issued 1,012,623 Class B
Units (referred to as the "Contributor Units") in exchange for certain real
property interests described in the Contribution Agreement (the "Property").
Contributor has assigned the Contributor Units to the Equity Holders (as defined
below). In connection with the issuance of Contributor Units, the Tenth Prior
Amendment to the Original Partnership Agreement, which set forth specific
agreements regarding certain additional rights and obligations of the
Contributor and its constituent partners as set forth on Schedule 1 to such
Tenth Prior Amendment (the "Equity Holders"), was executed. Such specific
agreements are described below.

                  All capitalized terms used in this Exhibit E-5 and not
otherwise defined shall have the meanings assigned in the Agreement.

SPECIFIC AGREEMENTS

                  1.       Right to Assign. Notwithstanding any other provision
of this Exhibit E-5 or of the Agreement, the Equity Holders shall have the right
to assign all or any portion of their Contributor Units, together with any and
all other rights of the Equity Holders pursuant to this Exhibit E-5 or the
Agreement, to one or more of the constituent partners or shareholders, members,
partners or beneficiaries of constituent partners of the Equity Holders as of
October 1, 1999, whether direct or indirect, without the need for the consent of
the General Partner or Limited Partners and without being subject to the right
of first refusal set forth in Section 11.3.A(a) of the Agreement, but in each
case subject to the restrictions and conditions set forth in Sections 11.3.C,
11.3.D, 11.3.E, 11.6.E and 11.6.F of the Agreement. Upon the delivery of written
notice of such an assignment to the General Partner, each assignee of
Contributor Units pursuant to the immediately preceding sentence shall be
admitted to the Partnership as a Substituted Limited Partner owning the
Contributor Units so assigned and having all of the rights of a Limited Partner
under the Agreement and this Exhibit E-5, subject only to such assignee
executing and delivering to the Partnership an acceptance of all of the terms
and conditions of the Agreement and such other documents or instruments as the
General Partner may reasonably require to effect such admission, in accordance
with Section 11.4.B of the Agreement. Each permitted assignee of any of the
Contributor Units, issued to the Contributor pursuant to the Contribution
Agreement and subsequently transferred to the Equity Holders, that is admitted
as a Substituted Limited Partner in accordance with this Section 1 or Article XI
of the Agreement, for so long as such Person owns any such Contributor Units, is
referred to in this Exhibit E-5 as an "Indirect Equity Holder." Upon
satisfaction of the condition described in the second sentence of this Section
1, the General Partner shall amend Exhibit A to the Agreement in the manner
described in Section 11.4.C of the Agreement. For purposes of Section 8.6 of the
Agreement, each Equity Holder and


<PAGE>   102

Indirect Equity Holder shall be entitled to exercise its right to require the
Partnership to redeem all or any portion of the Contributor Units assigned to it
by an Equity Holder at any time on or after October 1, 1999.

                  2.       Adjustments to Carrying Values. (a) The Carrying
Values of the Assets of the Partnership shall be adjusted in accordance with the
procedures described in Section 1.D of Exhibit B to the Agreement; provided,
however, that in order to minimize the administrative burden associated with the
adjustments required by this Section 2(a) in connection with the distribution of
the Cash Amount to an Equity Holder or an Indirect Equity Holder, the
Partnership shall make the adjustments to the Carrying Values of the
Partnership's assets (and the resulting adjustments to the Capital Accounts of
the Partners) only upon the happening of the most material event during the
calendar year that is described in Section 1.D(2) of Exhibit B to the Agreement
(the "Annual Adjustment") and; provided further that upon the distribution of
the Cash Amount to an Equity Holder or an Indirect Equity Holder or, at the
option of the General Partner, upon the occurrence of any other event described
in Section 1.D(2) of Exhibit B to the Agreement, that occurs during any year
other than as of the date of the Annual Adjustment, the Partnership shall, at
the time of such distribution, make adjustments to the Carrying Values of the
Partnership's assets in accordance with the procedures described in Section 1.D
of Exhibit B to the Agreement for purposes of adjusting the Capital Account of
an Equity Holder, or such Indirect Equity Holder who has exercised his
Redemption Right or such other affected Partner, but no such adjustments shall
be necessary at such time with respect to the Capital Account balances of
Partners who remain Partners through the date of the Annual Adjustment or are
otherwise not directly affected by any such other event.

                           (b)      Any determination of the fair market value
of Partnership assets pursuant to Section 1.D of Exhibit B to the Agreement (for
purposes of calculating Unrealized Gain or, Unrealized Loss), with respect to
adjusting the Carrying Values of Partnership assets in connection with the
exercise of Redemption Rights by an Equity Holder or any Indirect Equity Holder
shall be made by assuming that the aggregate fair market value of all
Partnership assets is equal to the aggregate Cash Amount that would be
distributed by the Partnership if all Partnership Units held by all Partners
(including the General Partner) were redeemed in exchange for the Cash Amount
with respect to each such Partnership Unit at such time, provided, however, such
valuation methodology shall not be utilized for purposes of determining the fair
market value of the Partnership's assets with respect to any such exercise of
Redemption Rights in contemplation of an assignment by or reorganization of the
Partnership for the benefit of creditors and any liquidation of the Partnership
related thereto or following the filing by (or in contemplation of a filing) by
the Partnership of a case under Title 11 of the U.S. Code.

                  3.       Allocations. Notwithstanding the provisions of
Section 2.C of Exhibit C to the Agreement, for purposes of allocating, items of
income, gain, loss and deduction with respect to the Property in the manner
required by Section 704(c) of the Code, the Partnership shall employ, and shall
cause any entity controlled by the Partnership which holds title to any of the
Property to employ the "traditional method" as set forth in Regulation Section
1.704-3(b).

                                    E-5 - 2
<PAGE>   103

                  4.       Obligation to Restore Deficit Capital Accounts. (a)
For purposes of this Section 4, the following terms shall have the meanings set
forth below:

                                    (i)      "Protected Amount" means, with
                           respect to any Protected Partner, an amount equal to
                           (i) the taxable gain, if any, that would be realized
                           by such Protected Partner if such Partner were to
                           dispose of its Partnership Interests for no
                           consideration other than the release or deemed
                           release of liabilities of the Partnership assumed by
                           or otherwise allocable to such Partner under Code
                           Section 752, as such hypothetical gain is determined
                           from time to time, less (ii) such Partner's share of
                           "qualified nonrecourse financing" as defined in Code
                           Section 465(b)(6) and the Regulations thereunder, as
                           such share is determined from time to time in
                           accordance with Regulations Section 1.752-3(a). The
                           Protected Amount allocable to any Protected Partner
                           may be modified from time to time by an amendment to
                           the Agreement or by execution of a written instrument
                           by and between such Protected Partner and the General
                           Partner, acting on behalf of the Partnership and
                           without the prior written consent of any other
                           Partner (whether or not Protected Partners).

                                    (ii)     "Protected Partner(s)" means that
                           or those Limited Partner(s) designated as Protected
                           Partner(s) on Exhibit A attached to the Tenth Prior
                           Amendment, as such designation may be modified from
                           time to time by the General Partner, whether by
                           express amendment to the Agreement or by execution of
                           a written instrument by and between any Protected
                           Partner(s) and the General Partner, acting on behalf
                           of the Partnership and without the prior consent of
                           other Limited Partners (whether or not Protected
                           Partners). For purposes hereof, any successor,
                           assignee, or transferee of Partnership Interests from
                           a Protected Partner, which successor, assignee or
                           transferee determines its basis in such Units by
                           reference to the basis of the predecessor, assignor
                           or transferor Protected Partner, shall be considered
                           a Protected Partner.

                  (b)      Notwithstanding any provision of the Partnership
Agreement to the contrary (including, without limitation, the second sentence of
Section 13.3 of the Partnership Agreement), upon liquidation of the Partnership
or upon the liquidation of the Partnership Interest of a Protected Partner, such
Protected Partner whose interest is being liquidated shall contribute to the
Partnership in accordance with Treasury Regulation Section
1.704-1(b)(2)(ii)(b)(2), the deficit balance, if any, in its Capital Account,
calculated after the allocation for such year of all items of Net Income, Net
Losses, Gross Income and Unrealized Gain or Unrealized Loss allocated in
accordance with Section 6.1 of the Agreement, Section 1.D of Exhibit B to the
Agreement, provided, however, that in no event shall such contribution
obligation for any Protected Partner exceed such Protected Partner's Protected
Amount. The obligation created pursuant to this Section 4(b) shall be for the
benefit of the Partnership, the General Partner, the creditors of the
Partnership or any other person to whom any debts, liabilities or obligations
are owed by (or who otherwise has any claim against) the Partnership or the
General Partner in its capacity as

                                    E-5 - 3
<PAGE>   104

general partner of the Partnership and shall be enforceable by such parties.
Each Protected Partner unconditionally and irrevocably waives any subrogation,
reimbursement or similar rights to which it might otherwise be entitled as the
result of its performance with respect to the obligation pursuant to this
Section 4(b), whether such rights arise with respect to the Partnership, another
Partner of the Partnership or a third party; provided, however, that the General
Partner shall in all events be entitled to enforce the contribution obligation
of a Protected Partner undertaken pursuant to Section 4(b). Notwithstanding
anything herein to the contrary, the obligation of a Protected Partner to
contribute amounts pursuant to this paragraph shall continue in full force and
effect in accordance with the terms hereof until one year following the transfer
or other disposition by such Protected Partner of its Partnership Interests
unless the Partnership and such Protected Partner agree otherwise. Unless
expressly agreed by the Partnership and the affected holders of Contributor
Units to the contrary in this or any other agreement, no holder of Contributor
Units who is not a Protected Partner shall have any obligation to contribute
amounts to the Partnership.

                  5.       Amendments. Notwithstanding any provision in the
Agreement to the contrary, the provisions of the Tenth Prior Amendment may be
waived or amended or otherwise modified with the prior written consent of
holders (being either the Equity Holders and/or the Indirect Equity Holders) of
more than seventy-five percent (75%) of the Contributor Units at the time
outstanding and without the consent of any other Limited Partner.
