Dear Limited Partner:

These consent solicitation materials are being sent to you and other limited
partners ("Limited Partners") of ERP Operating Limited Partnership ("ERP" or the
"Partnership") to inform you of, and solicit your consent to, certain amendments
(the "Amendments") of the Fourth Amended and Restated ERP Operating Limited
Partnership Agreement of Limited Partnership, as amended to date (the
"Partnership Agreement").  Upon receiving the consents required for the
effectuation of the Amendments, the Partnership Agreement will be amended and
restated as the Fifth Amended and Restated ERP Operating Limited Partnership
Agreement of Limited Partnership in the form attached as Appendix A to the
enclosed Consent Solicitation/Information Statement (the "Restated Partnership
Agreement") to reflect such Amendments.

The Amendments, as more fully described in the enclosed materials, are intended
primarily to  facilitate ERP's ability to enter into agreements with existing
property owners desiring to contribute their properties to ERP in consideration
for units of limited partnership interest in ERP ("OP Units") in a non-taxable
transaction.  Under these agreements, a consenting property owner that becomes a
Limited Partner ("Obligated Partner") would agree, upon liquidation of ERP, to
contribute to ERP up to a specified portion of the deficit capital account
balance (if any) of such Obligated Partner (referred to herein as a "Deficit
Restoration Obligation").  Equity Residential Properties Trust ("EQR"), the sole
general partner of ERP, and its Board of Trustees, believes that such agreements
will allow ERP to attract additional property acquisition opportunities, while
minimizing the restrictions on ERP's financing alternatives, by providing
property owners with a method to potentially reduce or eliminate the recognition
of taxable gain in the event any nonrecourse indebtedness encumbering the
property contributed to ERP by such property owners is paid off by ERP, in whole
or in part, after such property contribution is made.

The Amendments would facilitate these arrangements by (i) providing a mechanism
pursuant to which Obligated Partners would agree, upon the liquidation of ERP,
to contribute to the capital of ERP an amount equal to the lesser of its deficit
capital account balance or a pre-determined maximum amount (the "Restoration
Amount"), (ii) causing losses attributable to recourse liabilities of ERP to be
allocated to the Obligated Partners in a manner which could result in such
Obligated  Partners potentially having deficit capital account balances up to
each such Obligated Partner's Restoration Amount, thereby permitting an amount
of the recourse liabilities of ERP equal to the respective Restoration Amount of
each Obligated Partner to be allocated to such partners under Section 752 of the
Internal Revenue Code of 1986, as amended (the "Code").  It is contemplated that
such arrangements will be entered into primarily in connection with the
acquisition of new properties by ERP, including certain acquisitions in process.

 
Only Limited Partners who enter into such separate arrangements with ERP and
thereby become Obligated Partners will be affected by a Deficit Restoration
Obligation and the corresponding loss allocations.  The economic effect of a
Deficit Restoration Obligation and the corresponding loss allocations set forth
in the Amendments is that upon liquidation, the Obligated Partners could
potentially be liable for an amount of recourse liabilities of ERP (not to
exceed such Obligated Partner's respective Restoration Amount) that EQR, as the
sole General Partner of ERP, would otherwise be obligated to repay.
Accordingly, the Amendments will have no effect on the amount of cash that the
Limited Partners who are not Obligated Partners ("Non-Obligated Limited
Partners") would receive at any time during the term of ERP.  In addition, the
Amendments will not alter the amount of profits or losses that will be allocated
to the Non-Obligated Limited Partners.  Moreover, because the Amendments affect
only the allocation of recourse liabilities of ERP, and under current law, the
Non-Obligated Limited Partners would not receive any allocations of such
recourse liabilities whether or not the Amendments were adopted, the Amendments
are not expected to cause a reduction in the amount of liabilities to be
allocated to the Non-Obligated Limited Partners under Section 752 of the Code.

The Amendments regarding the deficit restoration provisions (the "Deficit
Restoration Amendments") require your consent to be effectuated, as described in
the accompanying material.  The Amendments also contain various other amendments
to the Partnership Agreement primarily of an administrative and mechanical
nature, some of which also require your consent to be effectuated, as more fully
described in the accompanying material.

The enclosed consent materials consist of: (i) a Consent
Solicitation/Information Statement, which further describes the Amendments,
their effects on ERP and its Limited Partners, and the consent requirements and
procedure; (ii) a copy of the Restated Partnership Agreement marked to indicate
the proposed Amendments; and (iii) a consent card to be completed and returned
in accordance with the instructions contained herein. EQR and its Board of
Trustees believe that the Amendments are in the best interest of ERP and its
Limited Partners and encourage you to carefully review the enclosed material and
to CONSENT to the Amendments in the manner described therein. The Amendments
will be effectuated upon the receipt of the required consent of the Limited
Partners and, therefore, EQR and its Board of Trustees encourage you to fill out
and return the enclosed consent card as soon as possible. This consent
solicitation is made on behalf of the Board of Trustees of EQR, as sole general
partner of ERP.

Sincerely,

/s/ Bruce C. Strohm

                       ERP OPERATING LIMITED PARTNERSHIP
                  CONSENT SOLICITATION/INFORMATION STATEMENT

     This Consent Solicitation/Information Statement is being furnished to the
holders ("Limited Partners") of units of limited partnership interest ("OP
Units") in ERP Operating Limited Partnership, an Illinois limited partnership
("ERP"), on behalf of the Board of Trustees of Equity Residential Properties
Trust, a Maryland real estate investment trust, the sole general partner of ERP
("EQR" or the "General Partner"). Limited Partners are hereby requested to
consent to certain amendments (the "Amendments") to the Fourth Amended and
Restated ERP Operating Limited Partnership Agreement of Limited Partnership, as
amended to date (the "Partnership Agreement"), which primarily add certain
limited deficit restoration provisions to the Partnership Agreement.

     This Consent Solicitation/Information Statement is also being provided to
Limited Partners to inform such Limited Partners that the General Partner has
determined to adopt certain additional amendments ("Additional Amendments") to
the Partnership Agreement which will be effectuated by the Chairman of the Board
of Trustees of EQR, as attorney in fact for the Limited Partners, pursuant to
Section 16 of the Partnership Agreement.

     Upon receiving the consents required for the effectuation of the
Amendments, the Partnership Agreement will be amended and restated as the Fifth
Amended and Restated ERP Operating Limited Partnership Agreement of Limited
Partnership (the "Restated Partnership Agreement") to reflect the Amendments and
the Additional Amendments, in the form attached hereto as Appendix A. In the
event that certain or all of the Amendments do not receive the required consent
of the Limited Partners, the Restated Partnership Agreement will reflect only
those Amendments receiving such consent, as well as the Additional Amendments.

     All descriptions and/or summaries of the Amendments and Additional
Amendments contained herein are qualified in their entirety by the full text of
the form of the Restated Partnership Agreement. Capitalized terms not otherwise
defined herein shall have the meaning ascribed to them in the Restated
Partnership Agreement.

     This Consent Solicitation/Information Statement is first being mailed to
Limited Partners on or about June 30, 1998.


                        DEFICIT RESTORATION AMENDMENTS

     The following is a description of the amendments which will add certain
limited deficit restoration provisions to the Partnership Agreement (the
"Deficit Restoration Amendments"). The Deficit Restoration Amendments are
indicated in boldface on the Restated Partnership Agreement, attached hereto as
Appendix A.

                                       1

 
     The General Partner believes that the Deficit Restoration Amendments are in
the best interests of the Limited Partners and recommends that each Limited
Partner vote FOR such amendments.


Reasons for the Deficit Restoration Amendments.

     The Deficit Restoration Amendments will amend certain Profit and Loss
allocations in the Partnership Agreement and add certain other provisions to the
Partnership Agreement pertaining to the obligation of a consenting Limited
Partner to restore a portion of the deficit (if any) in each Partner's Capital
Account upon liquidation of the Partnership (referred to herein as a "deficit
restoration obligation"). The General Partner believes the Deficit Restoration
Amendments will allow ERP to attract additional property acquisition
opportunities while minimizing the restrictions in ERP's financing alternatives,
by providing property owners with a method to potentially reduce or eliminate
the recognition of taxable gain in the event any nonrecourse indebtedness
encumbering property contributed to ERP by such property owners is repaid, in
whole or in part, by ERP after such contribution is made. See "Tax Consequences
of the Deficit Restoration Amendments." The Partnership Agreement currently
provides that no Limited Partner shall be obligated to repay any negative
balance which may exist in such Limited Partner's Capital Account. The Deficit
Restoration Amendments will (i) alter the Profit and Loss allocations to
consenting Limited Partners (the "Obligated Partners") to provide for Losses to
be allocated to such Obligated Partners in a manner which, under certain
conditions, could cause each Obligated Partner's deficit Capital Account balance
to equal a pre-determined maximum amount (the "Restoration Amount") for such
Obligated Partner (and to allocate Profits to reverse such Loss allocations),
and (ii) provide for such Obligated Partner to be required to contribute to the
Partnership, upon liquidation and after all allocations of Profit and Loss, the
lesser of the Restoration Amount or the amount of such Obligated Partner's
deficit Capital Account balance. Such Restoration Amount cannot be modified
without the prior written consent of the Obligated Partner. No Limited Partner
can become an Obligated Partner without such Limited Partner's prior written
consent.

     As of the date hereof, ERP has entered into certain agreements and
discussions with respect to individuals and entities becoming Obligated
Partners, including a pending acquisition of property by ERP from certain
affiliates of Lincoln Property Company Management Services, Inc. ("Lincoln").
The pending transaction with Lincoln (the "Lincoln Transaction") involves the
transfer of 26 apartment communities by Lincoln to ERP and certain of its
affiliates for a combination of cash, the assumption of liabilities and OP
Units. In connection with the Lincoln Transaction, ERP is obligated to use its
best efforts to effectuate the Deficit Restoration Amendments. In addition, upon
consummation of the Lincoln Transaction and adoption of the Deficit Restoration
Amendments, certain affiliates of Lincoln will become Obligated Partners with an
aggregate Restoration Amount of approximately $100 million. The value of the
properties to be acquired in connection with the Lincoln Transaction is
approximately $500 million, and such transaction is currently scheduled to close
in stages, beginning in the second quarter of 1998. The

                                       2

 
consummation of the Lincoln Transaction is not subject to the consent of the
Limited Partners, and therefore, such consent is not being requested. In
addition, although the consent of the Limited Partners is required to approve
the Amendments, approval of the Amendments is not a condition to the
consummation of the Lincoln Transaction. In addition to the Lincoln Transaction,
ERP has also entered into discussions with, but has not entered into any
definitive agreements or understandings, with various additional parties,
including an affiliate of a trustee of EQR. Such discussions have concerned
possible transactions between ERP and such additional parties pursuant to which
such parties would become Obligated Partners. However, despite such discussions,
there can be no assurance as to when or if such transactions will be
consummated.


Summary of the Deficit Restoration Amendments.

     Allocation of Losses. Section 7.2 of the Partnership Agreement sets forth
the method of Loss allocation. Section 7.2 currently provides that, after giving
effect to certain special allocations, Losses for any fiscal year shall be
allocated among the partners of ERP ("Partners") in proportion to their
Percentage Interests, so long as such allocation does not result in any Limited
Partner having an Adjusted Capital Account Deficit at the end of any fiscal
year.

     As amended, Section 7.2 would provide that after giving effect to certain
special allocations, Losses for any fiscal year would be allocated in the
following order of priority: (a) first, to the Partners, in proportion to their
respective Percentage Interests, provided that the Losses so allocated shall not
exceed the maximum amount of Losses that can be allocated without causing any
Partner to have an Adjusted Capital Account Deficit (excluding for this purpose
any increase to such Adjusted Capital Account Deficit for a Partner's actual
obligation to fund a deficit Capital Account balance); (b) second, to the
General Partner, until the General Partner's Adjusted Capital Account Deficit
(excluding for this purpose any increase to such Adjusted Capital Account
Deficit for the General Partner's actual obligation to fund a deficit Capital
Account balance) equals the excess of (i) the amount of Recourse Liabilities
over (ii) the Aggregate Restoration Amount (defined as the total of all
Obligated Partners' Restoration Amounts); (c) third, to the Obligated Partners,
in proportion to their respective Restoration Amounts, until such time as the
Obligated Partners have been allocated an aggregate amount of Losses equal to
the Aggregate Restoration Amount; and (d) thereafter, to the General Partner.

     Allocation of Profits. Section 7.1 of the Partnership Agreement sets forth
the method of Profit allocation. Section 7.1 currently provides that after
giving effect to certain special allocations, Profits for any fiscal year shall
be allocated among the Partners in proportion to their respective Percentage
Interests. As amended, Section 7.1 would provide that after giving effect to
certain special allocations, Profits for any fiscal year would be allocated
first in the reverse order of any previously allocated Losses, to the extent of
such previously allocated Losses, and then among the Partners in proportion to
their respective Percentage Interests.

                                       3

 
     Negative Capital Accounts. Section 3.6 of the Partnership currently
provides that no Partner shall be required to pay ERP any amount of any deficit
or negative balance which may exist in such Partner's Capital Account. As
amended, Section 3.6 would provide that upon the liquidation of the Partnership,
if any Obligated Partner has a deficit balance in its Capital Account (after
giving effect to all contributions, distributions and allocations for all prior
periods), such Obligated Partner shall contribute to the capital of ERP an
amount equal to such deficit Capital Account balance, with such payment being
made by the end of the fiscal year of ERP's liquidation or dissolution (or, if
later, within ninety (90) days following the liquidation or dissolution of ERP).
Amended Section 3.6 would also provide that an Obligated Partner ceases to be an
Obligated Partner for purposes of Section 3.6 twelve months after the exchange
by such Obligated Partner of all OP Units held by such Obligated Partner for
common shares of beneficial interest of EQR unless, at the time of such
exchange, or during the 12-month period immediately following such exchange, an
action has commenced with regard to ERP under the federal bankruptcy laws or
similar laws.

     Definition of Adjusted Capital Account Deficit; Allocations Upon
Liquidation. The Deficit Restoration Amendments revise the definition of
Adjusted Capital Account Deficit in the Partnership Agreement so that such term
means the balance in a Partner's Capital Account after giving effect to the
adjustments currently described in such definition and adding the additional
adjustment of crediting to such Capital Account any amount a Partner is
obligated to restore pursuant to such Partner's agreement with the Partnership.
In connection with the Deficit Restoration Amendments, Section 14.2(C) of the
Partnership Agreement will be amended to clarify that upon any voluntary or
involuntary dissolution, liquidation or winding up of the Partnership, the
Company, as the holder of Preference Units, shall (subject to certain
limitations) be allocated items of gross income to the extent necessary to cause
its Capital Account balance to equal the amount established in the applicable
Other Securities Term Sheet, and that no other Partner shall receive any such
gross income allocation.

     Amendments Affecting Deficit Restorations. The Deficit Restoration
Amendments provide that Sections 7.1 and 7.2 of the Partnership Agreement, which
set forth the method of Profit and Loss allocation, shall not be amended in a
manner which adversely affects an Obligated Partner without the written consent
of such Obligated Partner. The Deficit Restoration Amendments also provide that
amended Section 3.6(B), which sets forth when an Obligated Partner ceases to be
an Obligated Partner, may not be amended without the consent of two-thirds in
number of the Obligated Partners, and, in addition, that no such amendment shall
adversely affect an Obligated Partner without such Obligated Partner's written
consent.

Federal Income Tax Consequences of the Deficit Restoration Amendments

     The tax discussion set forth below is not and is not intended to be, nor
should it be construed as, legal or tax advice to any particular holder of OP
Units. Accordingly, holders of OP Units are strongly urged to consult their own
tax advisors as to the Federal income tax

                                       4

 
consequences of the Deficit Restoration Amendments and any other consequences of
the Deficit Restoration Amendments under state, local and foreign tax laws.

     A Limited Partner who contributes property to ERP in consideration for OP
Units will initially have an adjusted basis in his or her OP Units equal to (i)
the adjusted tax basis of the property contributed to ERP by such partner plus
(ii) such partner's share of the liabilities of ERP. Such ERP Unit holder's
adjusted basis in such OP Units will subsequently be reduced by allocations of
Losses and distributions of money to such Limited Partner and increased by such
Limited Partner's share of Profits. Under Section 731 of the Code, an ERP
Unitholder is deemed to receive a distribution of money to the extent such
partner's share of ERP liabilities is reduced. Accordingly, if a property owner
contributes property to ERP, such partner's adjusted tax basis in his or her OP
Units would initially be equal to the adjusted tax basis of the property
contributed to ERP. However, if the property is encumbered by indebtedness and
such indebtedness is paid off by ERP, then such partner may be deemed to have
received a distribution of money in excess of such Limited Partner's adjusted
basis in his or her OP Units (thereby triggering gain recognition), unless such
Limited Partner receives an allocation of other liabilities of ERP to offset
this deemed cash distribution.

     The purpose of adopting the Deficit Restoration Amendments is to enable ERP
to allocate Recourse Liabilities of ERP to Limited Partners to potentially
reduce or eliminate the recognition of gain upon the contribution of certain
property to ERP and the reduction or repayment by ERP of the nonrecourse
Liabilities encumbering such properties. In general, under Section 752 of the
Code and the Treasury Regulations promulgated thereunder, Recourse Liabilities
of a partnership are allocated to those partners who would bear the economic
risk of loss for payment of such liabilities if all of the partnership's assets
were to become worthless and the partnership constructively liquidated. Because
a general partner of a limited partnership is liable for the Recourse
Liabilities of a limited partnership under state law, the general partner of a
limited partnership generally bears the economic risk of loss for all Recourse
Liabilities of a limited partnership. Therefore, in such case, all of the
Recourse Liabilities of a limited partnership would be allocated to the general
partner under Code Section 752. However, to the extent a limited partner has an
obligation to restore a deficit in its capital account upon liquidation of a
limited partnership, then such partner has essentially agreed to "step into the
shoes" of the general partner with respect to that portion of the Recourse
Liabilities of the partnership. Accordingly, the Deficit Restoration Obligation
can result in a limited partnership allocating Recourse Liabilities to a limited
partner to the extent such limited partner has agreed to restore any deficit in
its capital account and has no right of indemnification with respect to such
obligation.

     Because the economic risk of loss of an Obligated Partner (and the
corresponding allocation of Recourse Liabilities to such Obligated Partner) is
predicated upon the deficit balance in its Capital Account that would exist upon
liquidation (assuming all of ERP's assets became worthless), the Loss
allocations of ERP must be structured so that if all of ERP's assets were to
become worthless, the allocation of Losses attributable to the payment of
Recourse Liabilities of ERP

                                       5

 
would cause the Obligated Partners' deficit Capital Account balances to be equal
to their respective Restoration Amounts.

     To illustrate the foregoing, if all of ERP's assets were to become
worthless (the presumption for the allocation of Recourse Liabilities in the
Treasury Regulations under Section 752), ERP would have a Loss in excess of the
ERP partners' Capital Account balances equal to the amount of the Recourse
Liabilities of ERP. The purpose of the Deficit Restoration Amendments is to
cause such Loss to be allocated among the Partners in a manner that will cause
the Obligated Partners' deficit Capital Account balances to be equal to the
amount of their Restoration Amount and thereby bear the economic risk of loss
for a portion of the Recourse Liabilities, equal to their respective Restoration
Amounts.

     The Deficit Restoration Amendments are intended to potentially achieve this
result by providing that after allocating the maximum amount of Losses to the
Partners without causing any of them to have an Adjusted Capital Account Deficit
(excluding for this purpose any increase to such Adjusted Capital Account
Deficit for a Partner's actual obligation to fund a deficit Capital Account
balance), Losses of ERP be allocated: (i) first, to EQR in an amount equal to
the total amount of Recourse Liabilities of ERP less the aggregate amount of
Restoration Amounts of all of the Obligated Partners; (ii) second, to the
Obligated Partners in proportion to their respective Restoration Amounts; and
(iii) thereafter, to the General Partner. The Profit allocations in the
Partnership Agreement would be revised to reverse the Loss allocations. Such
Loss allocations are intended to cause (x) EQR to potentially have a deficit
Capital Account balance equal to the amount of Recourse Liabilities less the
Restoration Amounts of all of the Obligated Partners, and (y) each of the
Obligated Partners to potentially have deficit Capital Account balances equal to
their respective Restoration Amounts and thereby bear the economic risk of loss
for a portion of the Recourse Liabilities, equal to their respective Restoration
Amounts.

     The economic effect of a Deficit Restoration Obligation and the
corresponding Loss allocation set forth in the Deficit Restoration Amendments is
that upon liquidation, the Obligated Partners could potentially be liable for
certain Recourse Liabilities of ERP that the General Partner would otherwise be
obligated to repay. Accordingly, the Deficit Restoration Amendments will have no
effect on the amount of cash that a Limited Partner who is not an Obligated
Partner (a "Non-Obligated Limited Partner") would receive at any time during the
term of ERP. In addition, the Deficit Restoration Amendments will not alter the
amount of Profit or Loss allocated to any Non-Obligated Limited Partners under
the Partnership Agreement. Moreover, because the Deficit Restoration Amendments
affect only the allocation of Recourse Liabilities of ERP and under current law,
the Non-Obligated Limited Partners would not receive any allocations of such
Recourse Liabilities even if the Deficit Restoration Amendments were not
adopted, the Deficit Restoration Amendments, in and of themselves, are not
expected to cause a reduction in the amount of liabilities to be allocated to
the Non-Obligated Limited Partners under Section 752 of the Code.

         SUMMARY OF AND REASONS FOR THE REMAINING AMENDMENTS REQUIRING
                            LIMITED PARTNER CONSENT

     The General Partner is also proposing the following amendments to the
Partnership Agreement. The General Partner determined that the proposed
amendments were advisable after a review of the agreements of limited
partnership of other publicly traded UPREITs and consultation with outside
counsel. These amendments are indicated in italics on the Restated Partnership
Agreement, attached hereto as Appendix A.

     The General Partner believes that the following proposed amendments are in
the best interests of the Limited Partners and recommends that each Limited
Partner vote FOR such amendments.

Amendments to Certain Definitions

     Summary. The definitions of "Company" and "General Partner" will be amended
to include any successor thereto (including, Equity Residential Properties Trust
as constituted as of the date of the Restated Partnership Agreement). In
addition, the definition of "Common Share" will be amended to include common
equity securities of any successor to the Company. Such amendments are referred
to herein as the "Successor Amendments."

     Reasons. The redemption right as currently contained in Section 3.2 of the
Partnership Agreement may adversely impact EQR's ability to pursue mergers or
other business combinations in which EQR is not the surviving entity. This
adverse impact could result because the redemption right provides that each
Limited Partner has the right to exchange its OP Units for common shares of
beneficial interest of EQR ("Common Shares"), without any reference to a
successor to EQR. By clarifying that the redemption right binds any successor to
EQR that results from a business combination or otherwise, the proposed
definitional amendments assure the Limited Partners that there will be an entity
to redeem their OP Units for common equity, whether it is EQR or a successor
thereto.

OP Unit Calculation for Contributing Partners.

     Summary. Section 3.2(B)(d) of the Partnership Agreement currently provides
that the number of OP units issued to a Contributing Partner under Section
3.2(B)(v) shall be equal to the quotient arrived at by dividing (i) the initial
Gross Asset Value of the property contributed as additional Capital
Contributions by (ii) the Market Price (as defined in Section 3.2(B)(d)). As
amended, Section 3.2(B)(d) will provide that rather than dividing the initial
Gross Asset Value of the contributed property by the Market Price, such value
will be divided by the contractual price per OP Unit agreed to by the General
Partner and the Contributing Partner. Such amendments are referred to herein as
the "Unit Calculation Amendments."

     Reasons. The General Partner believes it is in the best interests of the
Limited Partners to be able to attract and execute additional property
acquisition opportunities. This amendment will provide the General Partner with
additional flexibility when negotiating acquisitions of properties.

                                       7

 
Amendment of Definition of Market Price for Purposes of Section 3.2(C)

     Summary. The definition of "Market Price" for purposes of Section 3.2(C) of
the Partnership Agreement will be amended to mean either (a) the last reported
sale price per share of the Common Shares at the close of trading on the
Determination Date as reported in the Wall Street Journal (Midwest Edition) or
such other reportable stock price reporting service as may be selected by the
General Partner, or (b) in the event that the Common Shares were not traded on
such Determination Date, then the last reported sale price as aforesaid on the
most recent day that the Common Shares were traded. Such amendments are referred
to herein as the "Market Price Amendments."

     Reasons. The General Partner believes that it is in the best interests of
the Limited Partners to provide more certainty as to the definition of Market
Price for purposes of Section 3.2(C). This amendment provides that Market Price
will be determined using the closing price of the Common Shares on one day
instead of a 10-day trailing average.

Adjustment by General Partner of ERP Unit Exchange Ratio if EQR's Shareholder
Rights Plan is Triggered

     Summary. Section 3.2(C) of the Partnership Agreement will be amended to
provide that if the General Partner adopts a shareholder rights or similar plan,
then the General Partner, in its sole discretion, will in good faith make an
equitable adjustment to the exchange ratio of Common Shares for OP Units to
protect the value of the OP Units if any rights or similar securities issued
under such plan become exercisable and expire prior to a Determination Date.
Such amendments are referred to herein as the "Shareholders' Rights Amendments."

     Reasons. EQR may adopt a shareholder rights plan or similar arrangement
whereby holders of Common Shares would receive certain rights entitling them to
acquire securities of EQR at a discount to their market price under certain
circumstances. If EQR adopted such a plan and the rights issued thereunder were
exercised, it is possible that the value of the OP Units would be diluted to the
extent of the discount to market price at which securities of EQR were issued
pursuant to the exercise of such rights. To prevent such dilution, the General
Partner believes it is in the Limited Partners best interests that the General
Partner have the ability to equitably adjust the ERP Unit exchange ratio set
forth in Section 3.2(C) of the Partnership Agreement.


Elimination of Restrictions on Pledgees of Limited Partners

     Summary. Section 12 of the Partnership Agreement will be amended by
deleting the proviso contained in subsection (B)(i)(x) thereof which effectively
limits a Limited Partner's ability to pledge its OP Units by requiring that the
pledgee subordinate its rights to those of the Partnership and that the pledgee
defer exercising its right to realize on the collateral until the expiration of
any lock-up period under the terms of any agreement between the Partnership and
the pledging Limited Partner. Such amendments are referred to herein as the
"Pledgee Amendments."

                                       8

 
     Reasons. The General Partner believes it is in the best interests of the
Limited Partners to allow them to pledge more freely their OP Units without the
current restrictions which might make it more difficult for a Limited Partner to
pledge his OP Units.

Rights of Assignees of Partnership Interest

     Summary. Section 12(B)(ii) of the Partnership Agreement will be amended to
provide assignees of OP Units ("Assignees") the right to exercise the exchange
rights provided to holders of OP Units by Section 3.2(C) of the Partnership
Agreement. Such amendment will allow Assignees to exchange their interests for
Common Shares, or, at the option of the General Partner, cash, pursuant to
Section 3.2(C) of the Partnership Agreement. Additionally, Section 12(B)(ii)
will be amended to provide that Assignees will not be bound by any amendments,
modifications or changes to the Partnership Agreement that would adversely
affect their rights under Section 12(B)(ii) without their consent. In connection
with the foregoing amendment, a new definition, "Assignee," will be added to
Section 2.1 of the Partnership Agreement. Such amendments are referred to herein
as the "Assignee Amendments."

     Reasons. The General Partner believes it is in the best interests of the
Limited Partners to allow their Assignees to exchange OP Units underlying their
economic interest pursuant to Section 3.2(C) of the Partnership Agreement. This
amendment should make it easier for Limited Partners to assign their limited
partner interests, as collateral or otherwise, and should make potential
Assignees more willing to accept such assignments.


                           THE ADDITIONAL AMENDMENTS

     Pursuant to Section 16 of the Partnership Agreement, the Chairman of the
Board of the General Partner has the power to amend certain sections of the
Partnership Agreement pursuant to a power of attorney granted by each Limited
Partner. Such amendments do not require the General Partner to solicit the
consent of any Limited Partner. Pursuant to this power of attorney, the General
Partner has determined to adopt the Additional Amendments summarized below,
effective upon receipt of the consent of the Limited Partners to the Amendments,
or such other time as the General Partner shall determine. These amendments are
indicated by underscoring on the Restated Partnership Agreement, attached hereto
as Appendix A.

- -    Section 3.1 of the Partnership Agreement regarding capital will be amended
     by substituting the current list of transactions pursuant to which OP Units
     have been issued with a reference to Schedule C to the Partnership
     Agreement, setting forth the Partners and the Percentage Interest in the
     Partnership held by each of them, as it may be adjusted in accordance with
     the terms of the Restated Partnership Agreement.

- -    Section 5(A) of the Partnership Agreement regarding the purposes and powers
     of the Partnership will be amended to expand such powers to include the
     power to conduct any other business that may be lawfully conducted by a
     limited partnership pursuant to the Act.

                                       9

 
- -    Section 9.1(iv) of the Partnership Agreement regarding the General
     Partner's power to sell and dispose of assets will be amended to clarify
     that the General Partner's power (without the consent of any Limited
     Partner) to acquire any assets or to sell any or all of the assets of the
     Partnership includes the power to merge, consolidate or combine the
     Partnership with any other Person.

- -    Section 9.5 of the Partnership Agreement regarding indemnification will be
     amended to clarify that the General Partner is entitled to reimbursement
     from the Partnership for any amounts paid by it in satisfaction of
     indemnification obligations owed by the General Partner to present or
     former trustees or officers of the General Partner, or other Persons
     indemnified by the General Partner.

- -    Section 17.2 of the Partnership Agreement regarding waivers of terms or
     conditions of the Partnership Agreement will be amended to clarify that a
     waiver must be writing and signed by all Partners who were intended, as
     determined in the reasonable discretion of the General Partner, to be the
     primary beneficiaries of the waived term or condition. In connection with
     this amendment, the General Partner currently contemplates requesting the
     Zell Partners and Starwood Partners to execute a waiver of their special
     voting and consent rights granted to the Zell Partners and Starwood
     Partners under Section 3.2(B)(e) and Article 16 of the Partnership
     Agreement.

          In addition to the above amendments, the Additional Amendments also
include several minor immaterial ministerial amendments designed to clarify or
provide certain mechanical improvements to the Partnership Agreement, as
indicated by underscoring on the Restated Partnership Agreement, attached hereto
as Appendix A.


                 CONSENT SOLICITATION/SOLICITATION INFORMATION

Purpose

          The Limited Partners are being asked by EQR, in its capacity as sole
     general partner of ERP, to consent to the Amendments. Consent to the
     Amendments by the Limited Partners is required for their approval and
     effectuation. The Additional Amendments will be effectuated by the Chairman
     of the Board of EQR, as attorney in fact for the Limited Partners.

Record Date

          The Partnership Agreement allows EQR, as sole general partner of ERP,
     to set a record date for Limited Partners entitled to consent to the
     Amendments. Only Limited Partners of record at the close of business on
     June 1, 1998 will be entitled to consent to the Amendments.

Consents Required

          Approval of the Amendments requires the affirmative consent of the
     Zell Partners, the Starwood Partners and the Limited Partners holding 67%
     of the total number of OP Units held by all Limited Partners (including all
     OP Units held by the Zell Partners and the Starwood

                                       10

 
     Partners) (collectively, the "Required Consent"). On June 1, 1998, Limited
     Partners held a total of 9,692,328 OP Units. Accordingly, approval of the
     Amendments requires the affirmative consent of the Zell Partners, the
     Starwood Partners and Limited Partners holding 6,493,860 OP Units
     (including all OP Units held by the Zell Partners and the Starwood
     Partners). Failure by a Limited Partner to affirmatively consent to the
     Amendments in accordance with the instructions given herein, or to abstain
     from granting such consent on the enclosed form of consent, will have the
     same effect as if such Limited Partner responded negatively on such form of
     consent. The Amendments shall be approved and become effective upon receipt
     by ERP of the Required Consent. The date on which the Amendments shall
     become effective is referred to herein as the "Effective Date."

Solicitation of Consents

          Consents will be solicited by mail, telephone and in person.
     Solicitations may be made by certain employees of EQR, none of whom will
     receive additional compensation for such solicitations. ERP will bear the
     expenses incurred in connection with the Consent Solicitation/Information
     Statement. Consents must be received prior to the Effective Date. In order
     to consent to the Amendments, please fill out and return the enclosed
     consent card as soon as possible.

Revocation of Consents

          Limited Partners may revoke their consents until the expiration of the
     Consent Period by dating, signing and delivering a written notice, which
     clearly expresses the revocation of consent, to ERP, or by delivering a
     properly executed, subsequently dated consent card withholding a previously
     granted consent.

               A.   The interest of a Partner in the Partnership is referred to
          as being evidenced by one or more "Units". Units may be either "OP
          Units" or "Preference Units":

                    (i)    An "OP Unit" is a unit of Partnership Interest that,
               as more particularly provided for below in Section 3.2(B), may be
               converted into either cash or one (1) Common Share.

                    (ii)   A "Preference Unit" is a unit of Partnership Interest
               having such rights, preferences and other privileges, variations
               and designations as may be determined by the General Partner in
               its sole and absolute discretion (but not in violation of the
               provisions of Section 3.2(B) or the terms of any other Preference
               Unit(s)). There may be more than one series or class of
               Preference Units having differing terms and conditions, but all
               Preference Units within a given series or class shall have the
               same rights, preferences and other privileges, variations and
               designations. A Preference Unit shall be convertible into one or
               more OP Units or be capable of being valued in OP Units. With
               respect to each series or class of Preference Units, the General
               Partner may also, in its discretion, determine and fix, among
               other terms and conditions, any of the following: (a) the series
               to which such Preference Units shall belong, (b) the distribution
               rate therefore, (c) the price at and the terms and conditions on
               which such Preference Units may be redeemed, (d) the amount
               payable in respect of such Preference Units in the event of
               involuntary or voluntary liquidation, (e) the terms and
               conditions on which such Preference Units may be converted, if
               such Preference Units are issued with the privilege of
               conversion, and (f) the number of such Preference Units to be
               issued as a part of such series. Once determined and fixed as
               herein provided, however, the terms and conditions of a
               particular series or class of Preference Units may not be changed
               without the written consent of the holders of at least 67% of the
               Preference Units within the class or series (or such greater
               percentage as may be provided for in the applicable Preference
               Unit Term Sheet or Other Securities Term Sheet, as the case may
               be).

          The aggregate total of all Units outstanding as of the date of this
          Agreement, including the making of the capital contributions referred
          to in Section 3.1 above, is ________________. As of the date of this
          Agreement, each Partner is deemed to hold Units as shown on Schedule
          C.

               B.   From time to time hereafter, subject to and in accordance
          with the provisions of this Section 3.2(B), the General Partner shall
          cause the Partnership to issue additional Units as follows:

                                      A-9

 
                    (i)    OP Units to the Company upon the issuance by the
               Company of additional Common Shares (other than in exchange for
               OP Units) and the contribution of the net proceeds thereof as a
               Capital Contribution to the Partnership as provided for in
               Section 3.3(B) below it being understood, however, that the
               Company may issue Common Shares in connection with share option
               plans, dividend reinvestment plans, restricted share plans or
               other benefit or compensation plans (for example, shares issued
               in lieu of fees or compensation) without receiving any proceeds
               and that the issuance of such Common Shares shall nonetheless
               entitle the Company to additional OP Units pursuant to this
               clause (i);

                    (ii)   OP Units to Partners (including itself) that hold
               Preference Units that are convertible into OP Units, upon the
               exercise of such conversion in accordance with the terms and
               conditions of the Preference Unit Term Sheet or Other Securities
               Term Sheet (each hereinafter defined) applicable thereto;

                    (iii)  OP Units to Partners holding OP Units (including
               itself) if and to the extent of each such Partner's participation
               in any reinvestment program contemplated by Section 3.3(C) below;

                    (iv)   Preference Units to the Company upon the issuance by
               the Company of securities other than Common Shares (whether debt
               or equity securities; ("Other Securities") and the contribution
               of the net proceeds thereof as a Capital Contribution to the
               Partnership as provided for in Section 3.3(B) below; and

                    (v)    in all other cases, OP Units and/or Preference Units,
               as determined by the General Partner, in its discretion, to
               existing or newly-admitted Partners (including itself), in
               exchange for the contribution by a Partner (the "Contributing
               Partner") of additional Capital Contributions to the Partnership.

          Issuance of OP Units as aforesaid shall be in accordance with the
          following:

                    (a)    the number of OP Units issued to the Company under
               clause (i) of this Section 3.2(B) shall be equal to the number of
               Common Shares issued;

                    (b)    the number of OP Units issued to a Partner under
               clause (ii) of this Section 3.2(B) shall be as provided for in
               the Preference Unit Term Sheet or the Other Securities Term Sheet
               (each hereinafter defined) pursuant to which the Preference Units
               being converted exist;

                                      A-10

 
                    (c)  the number of OP Units issued to a Limited Partner
               under clause (iii) of this Section 3.2(B) shall be as provided
               for in the applicable reinvestment program; and

                    (d)  the number of OP Units issued to a Contributing Partner
               under clause (v) of this Section 3.2(B) shall be equal to the
               quotient (rounded to the nearest whole number) arrived at by
               dividing (x) the initial Gross Asset Value of the property
               contributed as additional Capital Contributions (net of any debt
               to which such property is subject or assumed, and any cash paid
               to the Contributing Partner, by the Partnership in connection
               with such contribution) by (y) the contractual price per OP Unit
               agreed to by the General Partner and the Contributing Partner.

          Issuance of Preference Units as aforesaid shall be in accordance with
          the following:

                    (e)  Preference Units issued pursuant to clause (v) of this
               Section 3.2(B) shall have the terms and conditions specified in
               an agreement (a "Preference Unit Term Sheet") executed by and
               between the Partnership (at the direction and in the discretion
               of the General Partner) and the Contributing Partner and such
               Preference Unit Term Sheet shall thereupon be a part of this
               Agreement. The number of Preference Units issued to a
               Contributing Partner under clause (v) of this Section 3.2(B)
               shall be equal to the quotient (rounded to the nearest whole
               number) arrived at by dividing (x) the initial Gross Asset Value
               of the property contributed as additional capital contributions
               (net of any debt to which such property is subject or assumed by
               the Partnership in connection with such contribution) by (y) an
               amount provided for in the Preference Unit Term Sheet; and

                    (f)  Preference Units issued pursuant to clause (iv) of this
               Section 3.2(B) shall have economic terms substantially identical
               to those of the applicable Other Securities and such other terms
               and conditions, all of which are specified in an agreement (an
               "Other Securities Term Sheet") executed between the Partnership
               and the Company and such Other Securities Term Sheet shall
               thereupon be a part of this Agreement.

          Units may also be issued to some or all of the Partners holding
          Preference Units if and to the extent of such Partner's participation
          in any reinvestment program contemplated by Section 3.3(C) below. Upon
          the issuance of additional OP Units and/or Preference Units in
          accordance with the provisions of this Section 3.2(B), each recipient
          of such Units shall either execute this Agreement or a joinder to this
          Agreement (which joinder, as to Preference Units, may be a part of the
          applicable Preference Unit Term Sheet or Other Securities Term Sheet)
          and the Percentage Interests of all of the Partners shall thereupon be
          appropriately adjusted by the General Partner. Notwithstanding
          anything to the contrary contained herein, in no event shall any
          additional Preference Units or OP Units be issued (pursuant to this
          Section 3.2(B) or

                                      A-11

 
          otherwise) to the extent that the effect of such issuance would be to
          reduce the General Partner's Percentage Interest to fifty percent
          (50%) or less.

               C.   Subject to the further provisions of this Section 3.2(C),
          the Company hereby grants to each Limited Partner holding OP Units the
          right to request an exchange of any or all of its OP Units for Common
          Shares, with one OP Unit being exchangeable for one Common Share. Such
          right may be exercised by a Limited Partner at any time and from time
          to time upon not less than ten (10) days prior written notice to the
          Company. Upon receipt of such a request, the Company may, in its
          discretion, in lieu of issuing Common Shares, cause the Partnership to
          pay to such Limited Partner cash in an amount equal to the product
          arrived at by multiplying (i) the number of OP Units requested to be
          exchanged by such Limited Partner multiplied by (ii) the Market Price,
          with such payment to be made within ten (10) days after the Company's
          receipt of the Limited Partner's exercise notice as aforesaid;
          provided, however, that in calculating Market Price for this Section
          3.2(C) only, the "Determination Date" shall mean the trading date
          immediately preceding the date on which the Company receives notice
          from the holder of OP Units stating such holder's intention to
          exercise its right to request an exchange of its OP Units for Common
          Shares. As used in this Section 3.2(C), "Market Price" means either
          (a) the last reported sale price per share of the Common Shares at the
          close of trading on the Determination Date as reported in the Wall
          Street Journal (Midwest Edition) or such other reportable stock price
          reporting service as may be selected by the General Partner, or (b) in
          the event that the Common Shares were not traded on such Determination
          Date, then the last reported sale price as aforesaid on the most
          recent day that the Common Shares were traded. If the Company does not
          elect to make a cash payment, it shall be obligated to issue Common
          Shares as provided above. The Company shall at all times reserve and
          keep available out of its authorized but unissued Common Shares,
          solely for the purpose of effecting the exchange of OP Units for
          Common Shares, such number of Common Shares as shall from time to time
          be sufficient to effect the conversion of all outstanding OP Units not
          owned by the Company, and any Preference Units not owned by the
          Company that are convertible into OP Units (whether or not the
          conversion can then be effected). No Limited Partner shall, by virtue
          of being the holder of one or more OP Units and/or Preference Units,
          be deemed to be a shareholder of or have any other interest in the
          Company. In the event of any change in the outstanding Common Shares
          by reason of any share dividend, split, recapitalization, merger,
          consolidation, combination, exchange of shares or other similar
          corporate change (a "Recapitalization"), the number of OP Units held
          by each Partner (or into which Preference Units are or may be
          convertible, if applicable) shall be proportionately adjusted so that
          one OP Unit remains exchangeable for one Common Share without
          dilution. The Assignee of any Limited Partner may exercise the rights
          of such Limited Partner pursuant to this Section 3.2(C), 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, if the
          Company elects to make a cash

                                      A-12

 
          payment as provided herein, the cash payment shall be paid by the
          Partnership directly to such Assignee and not to such Limited Partner.
          If the Company adopts a shareholder rights plan or such other plan or
          arrangement pursuant to which the holders of Common Shares are
          entitled to receive rights or other securities upon the occurrence of
          specified events, then the General Partner shall in good faith make an
          equitable adjustment to the exchange ratio of Common Shares for OP
          Units, as the General Partner shall determine in its sole discretion,
          to protect the value of the OP Units if any rights or other securities
          issued under such plan or arrangement become exercisable and expire
          prior to a Determination Date. In the event the Company issues any
          Common Shares in exchange for OP Units pursuant to this Section
          3.2(C), the General Partner shall record the transfer on the books of
          the Partnership so that the Company is thereupon the owner and holder
          of such OP Units. Notwithstanding the foregoing provisions of this
          Section 3.2(C), a Limited Partner shall not have the right to exchange
          OP Units for Common Shares if (i) in the opinion of counsel for the
          Company, the Company would, as a result thereof, no longer qualify (or
          it would be likely that the Company no longer would qualify) as a real
          estate investment trust under the Code; or (ii) such exchange would,
          in the opinion of counsel for the Company, constitute or be likely to
          constitute a violation of applicable securities laws. In either such
          event, to the extent the consequences described in (i) or (ii) could
          be eliminated by reasonable action of the Company without any material
          detriment to the Company and at the expense of such Limited Partner(s)
          requesting such exchange, the Company shall take all such reasonable
          action to affect the exchange of OP Units for Common Shares by such
          Limited Partner(s) as herein provided.


          3.3  Additional Funds.
               
               A.  No Partner shall be assessed or, except as otherwise provided
          in this Agreement, required to contribute additional funds or other
          property to the Partnership. Any additional funds or other property
          required by the Partnership, as determined by the General Partner in
          its sole discretion, may, at the option of the General Partner and
          without an obligation to do so (except as provided for in Section
          3.3(B) below), be contributed by the General Partner or any other
          Partner (provided such other Partner is willing to do so and the
          General consents thereto, each in its sole and absolute discretion) as
          additional Capital Contributions. If and as the General Partner or any
          other Partner makes additional Capital Contributions to the
          Partnership, each such Partner shall receive additional OP Units
          and/or Preference Units as provided for in Section 3.2(B) above. The
          General Partner shall also have the right (but not the obligation) to
          raise any additional funds required for the Partnership in accordance
          with the provisions of Section 9.7(E) below and/or by causing the
          Partnership to borrow the necessary funds from third parties on such
          terms and conditions as the General Partner shall deem appropriate in
          its sole discretion. If the General Partner elects to cause the
          Partnership to borrow the additional funds, or if the Partnership
          issues a guaranty, indemnity or similar undertaking in connection with
          indebtedness of the Company as aforesaid, in any such case one or more
          of the Partnership's assets may be encumbered to secure the loan or


                                     A-13


 
          undertaking. Except as provided for in Section 3.3(C) below, no
          Limited Partner shall have the right to make additional Capital
          Contributions to the Partnership without the prior written consent of
          the General Partner.

               B.  Except for (i) the capitalization of any wholly owned entity
          of the General Partner which is the general partner of a partnership
          having the Partnership as a limited partner, (ii) the net proceeds
          generated by the issuance of Other Securities that evidence debt (and
          are not equity securities) that are loaned by the Company to the
          Partnership, and (iii) where, in the good faith opinion of the
          Company, the net proceeds generated by the issuance of Other
          Securities (whether for debt or equity) are retained by the Company
          for a valid business reason consistent with the purposes of the
          Partnership and such retention does not materially adversely affect
          the Limited Partners, the net proceeds of any and all funds raised by
          or through the Company through the issuance of Common Shares or Other
          Securities shall be contributed to the Partnership as additional
          Capital Contributions, and in such event the Company shall be issued
          additional Units pursuant to Section 3.2(B) above.

               C.  If the General Partner creates and administers a reinvestment
          program in substantial conformance with a dividend reinvestment
          program which may be available from time to time to holders of the
          Common Shares, each Limited Partner holding OP Units shall have the
          right to reinvest any or all cash distributions payable to it from
          time to time pursuant to this Agreement by having some or all (as the
          Limited Partner elects) of such distributions contributed to the
          Partnership as additional Capital Contributions, and in such event the
          Partnership shall issue to each such Limited Partner additional OP
          Units pursuant to clause (iv) of Section 3.2(B) above, or the General
          Partner may elect to cause distributions with respect to which a
          Limited Partner has elected reinvestment to be contributed to the
          Company in exchange for the issuance of Common Shares. At the option
          of the General Partner, such a program may also be made available with
          respect to Preference Units.


          3.4  Capital Accounts.  A separate capital account ("Capital Account")
     shall be maintained for each Partner.

               A.  To each Partner's Capital Account there shall be credited
          such Partner's Capital Contributions, such Partner's distributive
          share of Profits and any items in the nature of income or gain which
          are specially allocated pursuant to Section 7.3, Section 7.4 or
          Section 14.2(C) hereof, and the amount of any Partnership liabilities
          assumed by such Partner or which are secured by any Partnership
          property distributed to such Partner.

               B.  To each Partner's Capital Account there shall be debited the
          amount of cash and the Gross Asset Value of any Partnership property
          distributed to such Partner pursuant to any provision of this
          Agreement, such Partner's distributive share of Losses and any items
          in the nature of expenses or losses which are specially allocated
          pursuant to Section 7.3 or Section 7.4 hereof, and the amount of any


                                     A-14


 
          liabilities of such Partner assumed by the Partnership or which are
          secured by any property contributed by such Partner to the
          Partnership.

               C.  In the event all or a portion of a Partnership Interest is
          transferred in accordance with the terms of this Agreement (including
          a transfer of OP Units in exchange for Common Shares, pursuant to
          Section 3.2(C)), the transferee shall succeed to the Capital Account
          of the transferor to the extent it relates to the transferred
          Partnership Interest.

               D.  In determining the amount of any liability for purposes of
          Sections 3.4(A) and 3.4(B) above, there shall be taken into account
          Code Section 752(c) and any other applicable provisions of the Code
          and Regulations.

               E.  This Section 3.4 and the other provisions of this 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, or the Partners) are computed
          in order to comply with such Regulations, the General Partner may make
          such modification, provided that it is not likely to have a material
          effect on the amounts distributed to any Partner pursuant to Section
          14 below 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 1.704-1(b)(2)(iv)(g), and (ii) make any
          appropriate modifications in the event unanticipated events (for
          example, the acquisition by the Partnership of oil or gas properties)
          might otherwise cause this Agreement not to comply with Regulations
          Section 1.704-1(b).


          3.5  Interest on and Return of Capital.

               A.  No Partner shall be entitled to any interest on its Capital
          Account or on its contributions to the capital of the Partnership.

               B.  Except as expressly provided for in this Agreement, no
          Partner shall have the right to demand or to receive the return of all
          or any part of his capital contributions to the Partnership and there
          shall be no priority of one Partner over the other as to the return of
          capital contributions or withdrawals or distributions of profits and
          losses. No Partner shall have the right to demand or receive property
          other than cash in return for the contributions of such Partner to the
          Partnership.


                                     A-15



 
          3.6  Negative Capital Accounts.

               A.  Except as provided in the next sentence and Section 3.6(B),
          no Partner shall be liable to the Partnership or to any other Partner
          for any deficit or negative balance which may exist in such Partner's
          Capital Account. If any Obligated Partner has a deficit balance in its
          Capital Account (after giving effect to all contributions,
          distributions, allocations and adjustments to Capital Accounts for all
          periods), each such Obligated Partner shall contribute to the capital
          of the Partnership an amount equal to its respective deficit balance;
          such obligation to be satisfied by the end of the fiscal year of
          liquidation (or, if later, within ninety (90) days following the
          liquidation and dissolution of the Partnership.) Such contributions
          shall be used to make payments to creditors of the Partnership and
          such Obligated Partners (i) shall not be surrogate to the rights of
          any such creditor against the General Partner, the Partnership,
          another Partner or any person related thereto, and (ii) hereby waive
          any right to reimbursement, contribution or similar right to which
          such Obligated Partners might otherwise be entitled as a result of the
          performance of its obligations under this Agreement.

               B.  Except as otherwise agreed in writing, by the General Partner
          and an Obligated Partner, prior to the time of admission of such
          Obligated Partner to the Partnership, notwithstanding any other
          provision of this Agreement, an Obligated Partner shall cease to be an
          Obligated Partner for purposes of this Section 3.6 upon an exchange by
          such Obligated Partner of all remaining OP Units for Common Shares
          (pursuant to Section 3.2(C) or otherwise) 12 months after the date of
          such exchange by such Obligated Partner unless at the time of, or
          during the 12 month period following, such exchange, there has been:

                    (i)  An entry of a decree or order for relief in respect of
               the Partnership by a court having jurisdiction over a substantial
               part of the Partnership's assets, or the appointment of a
               receiver, liquidator, Assignee, custodian, trustee, sequestrator
               (or other similar official) of the Partnership or of any
               substantial part of its property, or ordering the winding up or
               liquidation of the Partnership's affairs, in an involuntary case
               under the federal bankruptcy laws, as now or hereafter
               constituted, or any other applicable federal or state bankruptcy,
               insolvency or other similar law; or

                    (ii)  The commencement against the Partnership of an
               involuntary case under the federal bankruptcy laws, as now or
               hereafter constituted, or any other applicable federal or state
               bankruptcy, insolvency or other similar law; or

                    (iii)  The commencement by the Partnership of a voluntary
               case under the federal bankruptcy laws, as now or hereafter
               constituted, or


                                     A-16


 
               any other applicable federal or state bankruptcy, insolvency or
               other similar law, or the consent by it to the entry of an order
               for relief in an involuntary case under any such law or the
               consent by it to the appointment of or taking possession by a
               receiver, liquidator, Assignee, custodian, trustee, sequestrator
               (or other similar official) of the Partnership or of any
               substantial part of its property, or the making by it of a
               general assignment for the benefit of creditors, or the failure
               of Partnership generally to pay its debts as such debts become
               due or the taking of any action in furtherance of any of the
               foregoing;

          provided that, after the passage of such 12 months, the Obligated
          Partner shall cease to be an Obligated Partner, at the first time, if
          any, that all of the conditions set forth in (i) through (iii) above
          are no longer in existence.

          This Section 3.6(B) shall not be amended without the consent of two-
     thirds in number of the Obligated Partners, provided, however, that no such
     amendment shall adversely affect an Obligated Partner without the written
     consent of such Obligated Partner.

          3.7 Limit on Contributions and Obligations of Partners. Neither the
     Limited Partner nor the General Partner shall be required to make any
     additional advances or contributions to or on behalf of the Partnership or
     to endorse any obligations of the Partnership.

          3.8  Redemption and Repurchase of Units. Notwithstanding any other
     provision of this Agreement which may be contrary to this Section 3.8, in
     the event of the proposed repurchase or redemption for cash by the Company
     of (i) Common Shares or, (ii) Other Securities with respect to which the
     Company had previously been issued Preference Units pursuant to Section
     3.2(B)(iv) of this Agreement, then, in such event, the Partnership shall
     provide cash to the Company concurrently with such repurchase or redemption
     for such purpose equal to the proposed repurchase or redemption price, and
     one OP Unit owned by the General Partner (or, in the case of redemption or
     repurchase by the Company of Other Securities contemplated by clause (ii)
     above, one Preference Unit owned by the General Partner which had been
     issued with respect to such Other Securities) shall be canceled with
     respect to each Common Share (or share of Other Securities) so repurchased
     or redeemed.

     4.  Principal Office. The principal office of the Partnership shall be
located at Two North Riverside Plaza, Suite 400, Chicago, Illinois 60606, or at
such other place as the General Partner may designate after giving written
notice of such designation to the other Partners.

     5.  Purposes and Powers of Partnership.

          A.  The purposes of the Partnership shall be to acquire, purchase,
     own, operate, manage, develop, redevelop, invest in, finance, refinance,
     sell, lease and otherwise deal with multifamily residential properties and
     assets related thereto, and interests therein, whether 

                                      A-17

 
     directly or indirectly, alone or in association with others, and to conduct
     any other business that may be lawfully conducted by a limited partnership
     pursuant to the Act. The purposes of the Partnership include, but are not
     limited to:

               (i) acquiring, developing, operating, leasing and managing
          multifamily residential properties and conducting any other lawful
          business relating thereto;

               (ii) financing, mortgaging, exchanging, selling, encumbering or
          otherwise disposing of all or any part of a multifamily residential
          property or any interest therein;

               (iii)  constructing, reconstructing, altering, modifying and
          subtracting from or adding to a multifamily residential property or
          any part thereof;

               (iv) organizing and holding partnership interests in partnerships
          owning or otherwise having an interest in, whether directly or
          indirectly, one or more multifamily residential properties; and

               (v) in general, the making of any investments or expenditures,
          the borrowing and lending of money and the taking of any and all
          actions which are incidental or related to any of the purposes recited
          above.

     It is agreed that each of the foregoing is an ordinary part of the
     Partnership's business and affairs. Property may be acquired subject to, or
     by assuming, the liens, encumbrances, and other title exceptions which
     affect such property. The Partnership may also be a partner, general or
     limited, in partnerships, general or limited, and joint ventures created to
     accomplish all or any of the foregoing.

          B. The Partnership purposes may be accomplished by taking any action
     which is not prohibited under the Act and which is related to the
     acquisition, ownership, development, improvement, operation, management,
     financing, leasing, exchanging, selling or otherwise encumbering or
     disposing of all or any portion of the assets of the Partnership, or any
     interest therein.

     6. Term. The term of the Partnership shall continue until the Partnership
is terminated upon the occurrence of an event described in Section 14.1 below.

     7. Allocations.

          7.1  Allocation of Profits. After giving effect to the allocations
     set forth in Section 7.3 and 7.4, Profits for any fiscal year shall be
     allocated to the Partners in the following order of priority:

               A. First, to the General Partner to the extent that the
          cumulative Losses allocated to the General Partner pursuant to Section
          7.2(D) exceed the


                                      A-18

 
          cumulative Profits allocated to the General Partner pursuant to this
          Section 7.1(A);

               B. Second, to each Partner to the extent of and in proportion to
          the amount by which the cumulative Losses allocated to such Partner
          pursuant to Section 7.2(C) exceed the cumulative Profits allocated to
          such Partner pursuant to this Section 7.1(B);

               C. Third, to the General Partner to the extent that the
          cumulative Losses allocated to the General Partner pursuant to Section
          7.2(B) exceed the cumulative Profits allocated to the General Partner
          pursuant to this Section 7.1(C);

               D. Fourth, to each Partner to the extent of and in proportion to
          the amount by which the cumulative Losses allocated to such Partner
          pursuant to Section 7.2(A) exceed the cumulative Profits allocated to
          such Partner pursuant to this Section 7.1(D); and

               E. Thereafter, to the Partners in accordance with their
          respective Percentage Interests.

          7.2 Losses. After giving effect to the allocations set forth in
     Sections 7.3 and 7.4, Losses for each fiscal year shall be allocated to the
     Partners in the following order of priority:

               A. First, to the Partners, in proportion to their respective
          Percentage Interests; provided that Losses allocated pursuant to this
          Section 7.2(A) shall not exceed the maximum amount of Losses that can
          be allocated without causing any Partner to have an Adjusted Capital
          Account Deficit (excluding for this purpose any increase to such
          Adjusted Capital Account Deficit for a Partner's actual obligation to
          fund a deficit Capital Account balance, including the obligation of an
          Obligated Partner to fund a deficit Capital Account balance pursuant
          to Section 3.6 hereof);

               B. Second, to the General Partner, until the General Partner's
          Adjusted Capital Account Deficit (excluding for this purpose any
          increase to such Adjusted Capital Account Deficit for the obligation
          of any General Partner to actually fund a deficit Capital Account
          balance) equals the excess of (i) the amount of Recourse Liabilities
          over (ii) the Aggregate Restoration Amount;

               C. Third, to the Obligated Partners, in proportion to their
          respective Restoration Amounts, until such time as the Obligated
          Partners have been allocated in aggregate amount of Losses pursuant to
          this Section 7.2(C) equal to the Aggregate Restoration Amount; and

               D. Thereafter, to the General Partner.


                                      A-19

 
          This Section 7.2 together with Section 7.1 shall control
     notwithstanding any reallocation or adjustment of taxable income, loss or
     other items by the IRS or any other taxing authority; provided, however,
     that neither the Partnership nor the General Partner (nor any of their
     respective affiliates) is required to indemnify any Obligated Partner (or
     its affiliates) for the loss of any tax benefit resulting from any
     reallocation or adjustment of taxable income, loss or other items by the
     IRS or other taxing authority. The provisions of Section 7.1 and this
     Section 7.2 shall not be amended in a manner which adversely affects an
     Obligated Partner (without consent of such Obligated Partner), provided
     that the General Partner may amend Schedule D to add additional Obligated
     Partners.

          7.3 Special Allocations. The following special allocations shall be
     made in the following order:

               A. Minimum Gain Chargeback. Except as otherwise provided in
          Regulations Section 1.704-2(f), notwithstanding any other provision of
          this Section 7, if there is a net decrease in Partnership Minimum Gain
          during any fiscal year, each Partner shall be specially allocated
          items of Partnership income and gain for such fiscal year (and, if
          necessary, subsequent fiscal years) in an amount equal to such
          Partner's share of the net decrease in Partnership Minimum Gain,
          determined in accordance with Regulations Section 1.704-2(g). The
          items to be so allocated shall be determined in accordance with
          Regulations Sections 1.704-2(f)(6) and 1.704-2(j)(2). This Section
          7.3(A) is intended to comply with the minimum gain chargeback
          requirement in Section 1.704-2(f) of the Regulations and shall be
          interpreted consistently therewith.

               B. Partner Minimum Gain Chargeback. Except as otherwise provided
          in Regulations Section 1.704-2(i)(4), notwithstanding any other
          provision of this Section 7, if there is a net decrease in Partner
          Nonrecourse Debt Minimum Gain attributable to a Partner Nonrecourse
          Debt during any Partnership fiscal year, each Partner who has a share
          of the Partner Nonrecourse Debt 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 fiscal year (and, if necessary,
          subsequent fiscal years) in an amount equal to such Partner's share of
          the net decrease in Partner Nonrecourse Debt Minimum Gain attributable
          to such Partner Nonrecourse Debt, determined in accordance with
          Regulations Section 1.704-2(i)(4). The items to be so allocated shall
          be determined in accordance with Regulations Sections 1.704-2(i)(4)
          and 1.704-2(i)(2). This Section 7.3(B) is intended to comply with the
          minimum gain chargeback requirement in Regulations Section 1.704-
          2(i)(4) and shall be interpreted consistently therewith.

               C. Qualified Income Offset. In the event any Partner unexpectedly
          receives any adjustments, allocations, or distributions described in
          Regulations Section 1.704-1(b)(2)(ii)(d)(4), Section 1.704-
          1(b)(2)(ii)(d)(5), or Section 1.704-1(b)(2)(ii)(d)(6), items of
          Partnership income and gain shall be specially


                                      A-20



          allocated to each such Partner in an amount and manner sufficient to
          eliminate, to the extent required by the Regulations, the Adjusted
          Capital Account Deficit of such Partner as quickly as possible,
          provided that an allocation pursuant to this Section 7.3(C) shall be
          made only if and to the extent that such Partner would have an
          Adjusted Capital Account Deficit after all other allocations provided
          for this Section 7 have been tentatively made, as if this Section
          7.3(C) were not in the Agreement.

               D. Gross Income Allocation. In the event any Partner has a
          deficit Capital Account at the end of any Partnership fiscal year
          which is in excess of the sum of (i) the amount such Partner is
          obligated to restore pursuant to any provision of this Agreement, and
          (ii) the amount such Partner is deemed to be obligated to restore
          pursuant to the penultimate sentences of Regulations Sections 1.704-
          2(g)(1) and 1.704-2(i)(5), each such Partner shall be specifically
          allocated items of Partnership income and gain in the amount of such
          excess as quickly as possible, provided that an allocation pursuant to
          this Section 7.3(D) shall be made only if and to the extent that such
          Partner would have a deficit Capital Account in excess of such sum
          after all other allocations provided for in this Section 7 have been
          made as if Section 7.3(C) hereof and this Section 7.3(D) were not in
          the Agreement.

               E. Preferential Gross Income Allocations. If and to the extent
          Partners receive distributions from the Partnership (other than (i)
          distributions pursuant to Section 14.2(C) in final liquidation of the
          Partnership), each such Partner shall be allocated an equal amount of
          Partnership gross income prior to any allocations of Profit and Loss
          pursuant to Sections 7.1 and 7.2 above. For purposes of this Section
          7.3(E), any payment with respect to a Preference Unit that, under the
          applicable Preference Unit Term Sheet or Other Securities Term Sheet,
          as the case may be, constitutes a payment in redemption of such
          Preference Unit shall not be considered a distribution except to the
          extent such payment is specifically attributable to accrued and unpaid
          preferred distributions with respect to such Preference Unit provided
          for in such Term Sheet.

               F. Nonrecourse Deductions. Nonrecourse Deductions for any fiscal
          year shall be allocated among the Partners in accordance with their
          respective Percentage Interests.

               G. Partner Nonrecourse Deductions. Any Partner Nonrecourse
          Deductions for any fiscal 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 Section 1.704-
          2(i)(1).

               H. Section 754 Adjustments. To the extent an adjustment to the
          adjusted tax basis of any Partnership asset pursuant to Code Section
          734(b) or Code Section 743(b) is required, pursuant to Regulations
          Section 1.704- 1(b)(2)(iv)(m)(2)


                                      A-21

 
          or Regulations Section 1.704-1(b)(2)(iv)(m)(4), to be taken into
          account in determining Capital Accounts as the result of a
          distribution to a Partner in complete liquidation of his interest in
          the Partnership, the amount of such adjustment to 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 gain or loss shall be specifically allocated to the Partners
          in accordance with their respective Percentage Interests in the event
          that Regulations Section 1.704-1(b)(2)(iv)(m)(2) applies, or the
          Partner to whom such distribution was made in the event that
          Regulations Section 1.704-1(b)(2)(iv)(m)(4) applies.

          7.4  Curative Allocations.  The allocations set forth in Sections
     7.3(A), 7.3(B), 7.3(C), 7.3(D), 7.3(F), 7.3(G) and 7.3(H) above (the
     "Regulatory Allocations") are intended to comply with certain requirements
     of the Regulations under Sections 704(b) and 514(c)(9)(E) of the Code. It
     is the intent of the Partners that, to the extent possible, all Regulatory
     Allocations shall be offset either with other Regulatory Allocations or
     with special allocations of other items of Partnership income, gain, loss,
     or deduction pursuant to this Section 7.4. Therefore, notwithstanding any
     other provision of this Section 7 (other than the Regulatory Allocations),
     the General Partner shall make such offsetting special allocations of
     Partnership income, gain, loss, or deduction in whatever manner it
     determines appropriate so that, after such offsetting allocations are made,
     each Partner's Capital Account balance is, to the extent possible, equal to
     the Capital Account balance such Partner would have had if the Regulatory
     Allocations were not part of the Agreement and all Partnership items were
     allocated pursuant to Sections 7.1 and 7.2(A) (subject, however, to Section
     7.3(E) above), and so that, to the greatest extent possible, such
     allocations comply with the Regulations under Code Section 514(c)(9)(E). In
     exercising its discretion under this Section 7.4, the General Partner shall
     take into account future Regulatory Allocations under Sections 7.3(A) and
     7.3(B) that, although not yet made, are likely to offset other Regulatory
     Allocations previously made under Sections 7.3(F) and 7.3(G).

          7.5  Tax Allocations: Code Section 704(c).

               A.  Income, gain, loss, and deduction with respect to any
          property contributed to the capital of the Partnership shall, solely
          for tax purposes, be allocated among the Partners so as to take
          account of any variation between the adjusted basis of such property
          to the Partnership for Federal income tax purposes and its initial
          Gross Asset Value in accordance with any permissible manner or manners
          under Code Section 704(c) and the Regulations thereunder.

               B.  In the event the Gross Asset Value of any Partnership asset
          is adjusted pursuant to the definition of "Gross Asset Value"
          contained in Section 2 above, subsequent allocations of income, gain,
          loss, and deduction with respect to such asset shall take account of
          any variation between the adjusted basis of such asset for Federal
          income tax purposes and its Gross Asset Value in the same manner or
          manners permitted under Code Section 704(c) and the Regulations
          thereunder.

                                      A-22

 
               C.  Any elections or other decisions relating to such allocations
          shall be made by the General Partner in any permissible manner under
          the Code or the Regulations that the General Partner may elect in its
          sole discretion. Allocations pursuant to this Section 7.5 are solely
          for purposes of Federal, state, and local taxes and shall not affect,
          or in any way be taken into account in computing, any Partner's
          Capital Account or share of Profits, Losses, other items, or
          distributions pursuant to any provision in this Agreement.

     8.   Cash Available For Distribution.

          8.1  Operating Cash Flow.  As used in this Agreement, "Operating Cash
     Flow" shall mean and be defined as all cash receipts of the Partnership
     from whatever source (but excluding Capital Cash Flow and excluding the
     proceeds of any additional Capital Contributions to the Partnership
     pursuant to Section 3.3 above) during the period in question in excess of
     all items of Partnership expense (other than non-cash expenses such as
     depreciation) and other cash needs of the Partnership, including, without
     limitation, amounts paid by the Partnership as principal on debts and
     advances, during such period, capital expenditures and any reserves (as
     determined by the General Partner) established or increased during such
     period. In the discretion of the General Partner, reserves may include cash
     held for future acquisitions. Operating Cash Flow shall be distributed to
     or for the benefit of the Partners of record as of the applicable Record
     Date not less frequently than annually, and shall be distributed: first to
     those Partners holding Preference Units to the extent of the respective
     priorities (if any) established by the applicable Preference Unit Term
     Sheets and Other Securities Term Sheets; and then the balance prorata among
     the Partners holding OP Units and the Partners holding Preference Units
     which, based on the provisions of the applicable Preference Unit Term
     Sheets and Other Securities Term Sheets, entitle such Partners to
     participate in such distributions on a pari passu basis with the holders of
     OP Units (the "Residual Operating Cash Flow Preference Units"), to each
     Partner based on the quotient (expressed as a percentage) arrived at by
     dividing (i) the sum of the OP Unit Value of any Residual Operating Cash
     Flow Preference Units held by that Partner and the number of OP Units held
     by that Partner by (ii) the sum of the OP Unit Value of all Residual
     Operating Cash Flow Preference Units issued and outstanding at the time and
     the total number of OP Units issued and outstanding at the time.
     Notwithstanding the foregoing, any incoming Limited Partners who were
     admitted during the applicable quarter (but excluding any incoming Partners
     who received Units from an existing Limited Partner) and who held Units as
     of an applicable Record Date, but held such Units for less than the entire
     period with respect to which an Operating Cash Flow distribution is to be
     paid, shall be entitled to receive a pro-rated portion of such Operating
     Cash Flow distribution otherwise payable to such Partner based on the
     number of days such Units were outstanding during the applicable period, or
     any other method of pro-ration deemed equitable by the General Partner, and
     in such event, if the General Partner, in its sole discretion, deems it
     necessary, the amount of the distribution payable to all other Partners
     shall be adjusted accordingly.

          8.2  Capital Cash Flow.  As used in this Agreement, "Capital Cash
     Flow" shall mean and be defined as collectively (a) gross proceeds realized
     in connection with the sale of

                                      A-23

 
     any assets of the Partnership, (b) gross financing or refinancing proceeds,
     (c) gross condemnation proceeds (excluding condemnation proceeds applied to
     restoration of remaining property) and (d) gross insurance proceeds
     (excluding rental insurance proceeds or insurance proceeds applied to
     restoration of property), less (a) closing costs, (b) the cost to discharge
     any Partnership financing encumbering or otherwise associated with the
     asset(s) in question, (c) the establishment of reserves (as determined by
     the General Partner, and which may include cash held for future
     acquisitions), and (d) other expenses of the Partnership then due and
     owing. Subject to Section 14.2 below, if applicable, Capital Cash Flow
     shall be distributed to or for the benefit of the Partners of record as of
     the applicable Record Date not less frequently than annually and shall be
     distributed: first to the Partners holding Preference Units to the extent
     of the respective priorities (if any) established by the applicable
     Preference Unit Term Sheets and Other Securities Term Sheets; and then the
     balance prorata among those Partners holding OP Units and those Partners
     holding Preference Units which, based on the provisions of the applicable
     Preference Unit Term Sheets and Other Securities Term Sheets, entitle such
     Partners to participate in such distributions on a pari passu basis with
     the holders of OP Units (the "Capital Cash Flow Preference Units"), to each
     Partner based on the quotient (expressed as a percentage) arrived at by
     dividing (i) the sum of the OP Unit Value of any Capital Cash Flow
     Preference Units held by that Partner and the number of OP Units held by
     that Partner by (ii) the sum of the OP Unit Value of all Capital Cash Flow
     Preference Units issued and outstanding at the time and the total number of
     OP Units issued and outstanding at the time. Notwithstanding the foregoing,
     the General Partner reserves the right to pro-rate distributions of Capital
     Cash Flow to incoming Limited Partners who were admitted during the
     applicable quarter (but excluding any incoming Partners who received Units
     from an existing Limited Partner) and who held Units as of the applicable
     Record Date but held such Units for less than the entire period with
     respect to which the Capital Cash Flow distribution is to be paid, based on
     the number of days such Units were outstanding during the applicable
     period, or any other method of pro-ration deemed equitable by the General
     Partner and, in such event, the amount of the distribution payable to all
     other Partners shall be adjusted accordingly.

          8.3  Consent to Distributions.  Each of the Partners hereby consents
     to the distributions provided for in this Agreement.

          8.4  Right to Limit Distributions.  The right of any Partner to
     receive distributions of any nature pursuant to the terms of this Agreement
     shall be subject to the terms of any agreement between such Partner and the
     Partnership limiting, restricting or providing rights of set-off with
     respect to such distributions.

     9.   Management of Partnership.

          9.1  General Partner.  The General Partner shall be the sole manager
     of the Partnership business, and shall have the right and power to make all
     decisions and take any and every action with respect to the property, the
     business and affairs of the Partnership and shall have all the rights,
     power and authority generally conferred by law, or necessary, advisable or
     consistent with accomplishing the purposes of the Partnership. All such
     decisions

                                      A-24

               (i)     operate any business normal or customary for the owner of
          or investor in multifamily residential property;

               (ii)    perform any and all acts necessary or appropriate to the
          operation of the Partnership assets, including, but not limited to,

          and the establishment of bank accounts in the name of the Partnership;

               (iii)   procure and maintain with responsible companies such

          finance and refinance the assets of the Partnership or any part
          thereof or interest therein, and in connection therewith, issue notes,
          bonds, securities and other undertakings and evidences of indebtedness
          and documents related thereto (including, without limitation,
          guaranty, indemnities and similar undertakings to support loans
          obtained or debt securities issued by the Company where the net
          proceeds thereof are either loaned to the Partnership or contributed
          to the Partnership as a Capital Contribution);

               (vii)   coordinate all accounting and clerical functions of the
          Partnership and employ such accountants, lawyers, property managers,
          leasing agents and other management or service personnel as may from
          time to time be required to carry on the business of the Partnership;

               (viii)  acquire any assets, and encumber, sell, ground lease or
          otherwise dispose of any or all of the assets of the Partnership
          (including by way of merger, consolidation or other combination with
          any other Person), or any part thereof or interest therein; and

               (ix)    organize one or more partnerships which are controlled,
          directly or indirectly, by the Partnership (including, without
          limitation, Equity Residential Properties Management Limited
          Partnership) and make any capital contributions required pursuant to
          the partnership agreements of any such partnerships.

                                      A-25

 
               (x) establish the date (the "Record Date") for the purpose of
          making any proper determination with respect to which Partners are
          entitled to receive distributions, consent to any matter for which the
          consent of Partners is permitted or required under any provision
          hereof, or otherwise be allocated rights hereunder.

          9.2  Limitations on Powers and Authorities of Partners.
     Notwithstanding the powers of the General Partner set forth in Section 9.1
     above, no Partner shall have the right or power to do any of the following:

               (a) do any act in contravention of this Agreement, or any
          amendment hereto;

               (b) do any act which would make it impossible to carry on the
          ordinary business of the Partnership, except to the extent that such
          act is specifically permitted by the terms hereof (it being understood
          and agreed that, except as hereafter provided in this Section 9.2, a
          sale of any or all of the assets of the Partnership, for example,
          would be an ordinary part of the Partnership's business and affairs
          and is specifically permitted hereby); or

               (c) confess a judgment against the Partnership.

          9.3  Limited Partners.  The Limited Partners shall have no right or
     authority to act for or to bind the Partnership and no Limited Partner
     shall participate in the conduct or control of the Partnership's affairs or
     business.

          9.4  Liability of General Partner.  The General Partner shall not be
     liable or accountable, in damages or otherwise, to the Partnership or to
     any other Partner for any error of judgment or for any mistakes of fact or
     law or for anything which it may do or refrain from doing hereafter in
     connection with the business and affairs of the Partnership except (i) in
     the case of fraud, willful misconduct (such as an intentional breach of
     fiduciary duty or an intentional breach of this Agreement) or gross
     negligence, and (ii) for other breaches of this Agreement, but the
     liability of the General Partner under this clause (ii) shall be limited to
     its interest in the Partnership as more particularly provided for in
     Section 9.8 below. The General Partner shall not have any personal
     liability for the return of any Limited Partner's capital.

          9.5  Indemnity.  The Partnership shall indemnify and shall hold the
     General Partner (and the officers and trustees thereof) harmless from any
     loss or damage, including without limitation reasonable legal fees and
     court costs, incurred by it by reason of anything it may do or refrain from
     doing hereafter for and on behalf of the Partnership or in connection with
     its business or affairs; provided, however, that (i) the Partnership shall
     not be required to indemnify the General Partner (or any officer or trustee
     thereof) for any loss or damage which it might incur as a result of its
     fraud, willful misconduct or gross negligence in the performance of its
     duties hereunder and (ii) this indemnification shall not relieve the
     General Partner of its proportionate part of the obligations of the
     Partnership as a Partner. In

                                      A-26

 
addition, the General Partner shall be entitled to reimbursement from the
Partnership for any amounts paid by it in satisfaction of indemnification
obligations owed by the General Partner to present or former trustees or
officers of the General Partner or its predecessors, or other Persons
indemnified by the General Partner, as provided for in or pursuant to the
Declaration of Trust and By-Laws of the General Partner or otherwise. The right
of indemnification set forth in this Section 9.5 shall be in addition to any
rights to which the person or entity seeking indemnification may otherwise be
entitled and shall inure to the benefit of the successors and assigns of any
such person or entity. No Partner shall be personally liable with respect to any
claim for indemnification pursuant to this Section 9.5, but such claim shall be
satisfied solely out of assets of the Partnership.

     9.6  Other Activities of Partners and Agreements with Related Parties . The
General Partner shall devote its full-time efforts in furtherance of the
Partnership business, it being expressly understood that, except for (i) the
Company's ownership interest in a partnership or a limited liability company of
which the Partnership is a partner or a member, respectively; (ii) the Company's
ownership of any qualified REIT subsidiary (within the meaning of the Code) or
any other entity which is a partner of a partnership or a member of a limited
liability company having the Partnership as a partner or member, respectively;
(iii) the Company's ownership of any entity that owns no more than a one percent
(1%) interest in any partnership, limited liability company or other entity;
(iv) borrowing (including the issuance of debt securities) where the net
proceeds thereof are loaned or contributed to the Partnership; (v) any activity
which the Board of Trustees of the General Partner, in its sole discretion, has
determined will have a material benefit to the General Partner and will not have
a material adverse effect on the Partnership; and (vi) activities incidental to
the Company's status and existence as a real estate investment trust, the
General Partner shall conduct all of its activities with respect to the
multifamily residential property business exclusively through the Partnership
and shall not conduct or engage in any way in any other business.

     9.7  Other Matters Concerning the General Partner.

          A.  The General Partner shall be protected in relying, acting or
     refraining from acting on any resolution, certificate, statement,
     instrument, opinion, report, notice, request, consent, order, bond,
     debenture, or other paper or document believed by it to be genuine and to
     have been signed or presented by the proper party or parties.

          B.  The General Partner may exercise any of the powers granted or
     perform any of the duties imposed by this Agreement either directly or
     through agents. The General Partner may consult with counsel, accountants,
     appraisers, management consultants, investment bankers and other
     consultants selected by it, each of whom may serve as consultants for the
     Partnership. An opinion by any consultant on a matter which the General
     Partner believes to be within its professional or expert competence shall
     be full and complete protection as to any action taken or omitted by the
     General Partner based on the opinion and taken or omitted in good faith.
     The General Partner shall not be responsible for the misconduct,
     negligence,
             
                                     A-27

 
          acts or omissions of any consultant or contractor of the Partnership
          or of the General Partner, and shall assume no obligations other than
          to use due care in the selection of all consultants and contractors.

               C.  No mortgagee, grantee, creditor or any other person dealing
          with the Partnership shall be required to investigate the authority of
          the General Partner or secure the approval of or confirmation by any
          Limited Partner of any act of the General Partner in connection with
          the conduct of the Partnership business.

               D.  The General Partner may retain such persons or entities as it
          shall determine (including the General Partner or any entity in which
          the General Partner shall have an interest or with which it is
          affiliated) to provide services to or on behalf of the Partnership.
          The General Partner shall be entitled to reimbursement from the
          Partnership for its out-of-pocket expenses (including, without
          limitation, amounts paid or payable to the General Partner or any
          entity in which the General Partner shall have an interest or with
          which it is affiliated) incurred in connection with Partnership
          business.  Such expenses shall be deemed to include those expenses
          required in connection with the administration of the Partnership such
          as the maintenance of Partnership books and records, management of the
          Partnership property and assets and preparation of information
          respecting the Partnership needed by the Partners in the preparation
          of their individual tax returns.

               E.  The General Partner may loan to the Partnership the net
          proceeds of loans obtained or debt securities issued by the Company so
          long as the terms of such loan to the Partnership are substantially
          equivalent to the corresponding loan obtained or debt securities
          issued by the Company.

          9.8  Partner Exculpation.  Except for fraud, willful misconduct and
     gross negligence, no Partner shall have any personal liability whatever,
     whether to the Partnership or to the other Partner, for the debts or
     liabilities of the Partnership or its obligations hereunder, and the full
     recourse of the other Partner shall be limited to the interest of that
     Partner in the Partnership.  To the fullest extent permitted by law, no
     officer, trustee or shareholder of the General Partner shall be liable to
     the Partnership for money damages except for (i) active and deliberate
     dishonesty established by a final judgment or (ii) actual receipt of an
     improper benefit or profit in money, property or services.  Without
     limitation of the foregoing, and except for fraud, willful misconduct and
     gross negligence, no property or assets of any Partner, other than its
     interest in the Partnership, shall be subject to levy, execution or other
     enforcement procedures for the satisfaction of any judgment (or other
     judicial process) in favor of any other Partner(s) and arising out of, or
     in connection with, this Agreement.  This Agreement is executed by the
     officers or general partners of each Partner solely as officers or partners
     of the same and not in their own individual capacities.  No advisor,
     trustee, officer, partner, employee, beneficiary, shareholder, participant
     or agent of any Partner (or of any partner of a Partner) shall be
     personally liable in any matter or to any extent under or in connection
     with this Agreement, and the Partnership, each Partner and their 
           
                                     A-28

 
     respective successors and assigns shall look solely to the interest of the
     other Partner in the Partnership for the payment of any claim or for any
     performance hereunder.

          9.9  General Partner Expenses and Liabilities.  All costs and
     expenses incurred by the Company in connection with its activities as the
     General Partner hereunder, all costs and expenses incurred by the Company
     in connection with its continued corporate existence, qualification as a
     real estate investment trust under the Code and otherwise, and all other
     liabilities incurred or suffered by the General Partner in connection with
     the pursuit of its business and affairs as contemplated hereunder and in
     connection herewith, shall be paid (or reimbursed to the Company, if paid
     by the Company) by the Partnership unless and to the extent that any such
     costs were paid by the Company in connection with the issuance of
     additional shares of beneficial interest of the Company as contemplated by
     Section 3.3(B) above.  Notwithstanding anything to the contrary contained
     herein, this Section 9.9 shall apply only to the extent that such costs,
     expenses or liabilities exceed any cash distributed to the General Partner
     by any wholly-owned subsidiary of the General Partner.

     10.  Banking.  The funds of the Partnership shall be kept in accounts
designated by the General Partner and all withdrawals therefrom shall be made on
such signature or signatures as shall be designated by the General Partner.

     11.  Accounting.
     
          11.1  Fiscal Year.  The fiscal year and taxable year of the
     Partnership (the "fiscal year") shall end on the last day of December of
     each year, unless another fiscal year end is selected by the General
     Partner.

          11.2  Books of Account.  The Partnership books of account shall be
     maintained at the principal office designated in Section 4 above or at such
     other locations and by such person or persons as may be designated by the
     General Partner.  The Partnership shall pay the expense of maintaining its
     books of account.  Each Partner shall have, during reasonable business
     hours and upon reasonable prior notice, access to the books of the
     Partnership and in addition, at its expense, shall have the right to copy
     such books.  The General Partner, at the expense of the Partnership, shall
     cause to be prepared and distributed to the Partners annual financial data
     sufficient to reflect the status and operations of the Partnership and its
     assets and to enable each Partner to file its federal income tax return.

          11.3  Method of Accounting.  The Partnership books of account shall
     be maintained and kept, and its income, gains, losses and deductions shall
     be accounted for, in accordance with sound principles of accounting
     consistently applied, or such other method of accounting as may be adopted
     hereafter by the General Partner.  All elections and options available to
     the Partnership for Federal or state income tax purposes shall be taken or
     rejected by the Partnership in the sole discretion of the General Partner.

          11.4  Section 754 Election.  In case of a distribution of property
     made in the manner provided in Section 734 of the Code (or any similar
     provision enacted in lieu thereof), 
               
                                     A-29

 
     or in the case of a transfer of any interest in the Partnership permitted
     by this Agreement made in the manner provided in Section 743 of the Code
     (or any similar provision enacted in lieu thereof), the General Partner, on
     behalf of the Partnership, will file an election under Section 754 of the
     Code (or any similar provision enacted in lieu thereof) in accordance with
     the procedures set forth in the applicable Regulations.

          11.5  Tax Matters Partner.  The General Partner is hereby designated
     the Tax Matters Partner (hereinafter referred to as the "TMP") of the
     Partnership and shall have all the rights and obligations of the TMP under
     the Code.

          11.6  Administrative Adjustments.  If the TMP receives notice of a
     Final Partnership Administrative Adjustment (the "FPAA") or if a request
     for an administrative adjustment made by the TMP is not allowed by the
     United States Internal Revenue Service (the "IRS") and the IRS does not
     notify the TMP of the beginning of an administrative proceeding with
     respect to the Partnership's taxable year to which such request relates (or
     if the IRS so notifies the TMP but fails to mail a timely notice of an
     FPAA), the TMP may, but shall not be obligated to, petition a Court for
     readjustment of partnership items.  In the case of notice of an FPAA, if
     the TMP determines that the United States District Court or Claims Court is
     the most appropriate forum for such a petition, the TMP shall notify each
     person who was a Partner at any time during the Partnership's taxable year
     to which the IRS notice relates of the approximate amount by which its tax
     liability would be increased (based on such assumptions as the TMP may in
     good faith make) if the treatment of partnership items on his return was
     made consistent with the treatment of partnership items on the
     Partnership's return, as adjusted by the FPAA.  Unless each such person
     deposits with the TMP, for deposit with IRS, the approximate amount of his
     increased tax liability, together with a written agreement to make
     additional deposits if required to satisfy the jurisdictional requirements
     of the Court, within thirty days after the TMP's notice to such person, the
     TMP shall not file a petition in such Court.  Instead, the TMP may, but
     shall not be obligated to, file a petition in the United States Tax Court.

     12.  Transfers of Partnership Interests.

          A.  General Partner.  In no event may the General Partner at any time
     assign, sell, transfer, pledge, hypothecate or otherwise dispose of all or
     any portion of its Partnership Interest, except by operation of law.

          B.  Limited Partner.

              (i)  No Limited Partner or substituted Limited Partner shall,
          without the prior written consent of the General Partner (which
          consent may be given or withheld in the sole discretion of the General
          Partner), sell, assign, distribute or otherwise transfer (a
          "Transfer") all or any part of his interest in the Partnership, except
          (w) by operation of law, testamentary disposition, gift (outright or
          in trust) or by sale, in each case to or for the benefit of his
          parent(s), spouse or descendants, (x) pledges or other collateral
          transfers effected by a Limited Partner to secure the repayment of a
          bona 
                       
                                     A-30

 
          fide loan or other obligation (a "Pledge") and the subsequent
          foreclosure or satisfaction thereof by transfer of such OP Units, (y)
          the exchange of OP Units for shares of beneficial interest of the
          Company, pursuant to Section 3.2(C) above, and (z) the distribution of
          OP Units or Preference Units by a Limited Partner to any of its direct
          or indirect  constituent partners or owners.  Notwithstanding the
          foregoing, each such transfer shall be subject to compliance with
          restrictions on transferability contained in any other applicable
          agreement executed by the transferor and compliance with applicable
          securities laws; the General Partner reserves the right to require an
          opinion of counsel regarding such matters in form and substance
          reasonably acceptable to the General Partner as a condition to any
          such Transfer.  Neither the conversion of a Preference Unit into one
          or more OP Units nor the conversion of OP Unit into a Common Share
          constitutes a Transfer.  A Limited Partner shall notify the General
          Partner of any Transfer of beneficial interest or other interest which
          occurs without a transfer of record ownership, as well as any pledge
          or other collateral transfer.  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.  A Limited Partner shall not be
          permitted to retire or withdraw from the Partnership except as
          expressly permitted by this Agreement.

               (ii) An Assignee, legatee, distributee or other transferee
          (whether by conveyance, operation of law or otherwise)(including any
          pledgee upon realization of its rights as a secured creditor) (a
          "Transferee") of all or any portion of a Limited Partner's interest in
          the Partnership shall be entitled to receive Profits, Losses and
          distributions hereunder attributable to such interest acquired by
          reason of such Transfer, from and after the effective date of the
          Transfer of such interest, and Assignees shall have the ability to
          exercise the rights granted to Limited Partners under Section 3.2(C),
          but shall not have any consent rights with respect to any matter
          presented to Limited Partners for approval; provided, however,
          anything in this Agreement to the contrary notwithstanding, (a) no
          Transfer by a Limited Partner shall be effective until such Transfer
          has been consented to by the General Partner except as provided in
          Section 12(B)(i); (b) without the prior written consent of the General
          Partner, no Transferee shall be considered a substituted Limited
          Partner except as provided in Section 12(B)(i)(w) and (z) and, in any
          event, until such Transferee shall have agreed to be bound by the
          terms of this Agreement and shall have executed a counterpart hereof;
          (c) the Partnership and the General Partner shall be entitled to treat
          the transferor of such interest as the absolute owner thereof in all
          respects, and shall incur no liability for the allocation of Profits
          and Losses or distributions which are made to such transferor until
          such time as the written instrument of Transfer has been received by
          the General Partner and the "effective date" of the Transfer has
          passed, (d) the General Partner shall have the right to require any
          such transferor to exchange the OP Units to which such interest
          relates for Common Shares, pursuant to Section 3.2(C) above, excluding
          Pledges of OP Units but including any transfer of the pledged OP
          Units, whether to the secured party or otherwise, pursuant to such
          party's exercise of its remedies under the Pledge or the related loan
          or obligation, and 
                  
                                     A-31

 
          (e) an Assignee shall not be bound by any amendments, modifications or
          changes to this Agreement that would adversely affect its rights under
          Section 3.2(C) or this Section 12(B)(ii) without its consent. The
          "effective date" of any Transfer shall be the last day of the month
          set forth on the written instrument of Transfer or such other date
          consented to in writing by the General Partner as the "effective
          date".

               (iii)  Notwithstanding anything to the contrary contained in this
          Section 12(B), (a) in the event a Limited Partner distributes in
          dissolution and liquidation all or any portion of its interest in the
          Partnership, the partners, shareholders or members (as the case may
          be) in such Limited Partner receiving such interest shall become
          substituted Limited Partners, and shall (upon agreeing to be bound by
          the terms of this Agreement and executing a counterpart hereof and/or
          any Preference Unit Terms Sheet or Other Securities Term Sheet)
          succeed to the rights, interests and obligations of such Limited
          Partner in the Partnership, in proportion to their respective
          interests in such Limited Partner, and (b) no Transfer shall be
          effective to the extent that such Transfer would, in the opinion of
          the General Partner (y) by treating the interest in the Partnership so
          transferred as if it had been exchanged for Common Shares in
          accordance with Section 3.2(C) above, violate the limitations on
          ownership of Common Shares contained in Article VII of the Declaration
          of Trust of the Company, or (z) violate any State or Federal
          securities laws.

          C.  Admission Adjustments.  The General Partner shall, when necessary,
     cause this Agreement to be amended from time to time to reflect the
     addition or withdrawal of Partners, and the issuance, conversion and
     redemption of any Preference Units and/or OP Units (including the
     corresponding adjustments to Percentage Interests).

          D.  Limitation.  Notwithstanding any other provision of this Agreement
     to the contrary, no sale, exchange, assignment, or other transfer or
     issuance of a Partnership Interest by or to any Partner shall be effective,
     if the effect of such transaction would be to cause the General Partner's
     Percentage Interest to decrease to a level of fifty percent (50%) or less.

     13.  Admission of New Partners.  The General Partner shall admit to the
Partnership as Limited Partners those persons and entities who are not already
Partners and who receive OP Units and/or Preference Units in accordance with the
provisions of this Agreement.

     14.  Termination, Liquidation and Dissolution of Partnership.

          14.1  Termination Events.  The Partnership shall be dissolved and
     its affairs wound up in the manner hereinafter provided upon the earliest
     to occur of the following events:

               (a)  December 31, 2080; or

               (b) the agreement of those Partners holding at least ninety
          percent (90%) of the Percentage Interests of all of the Partners,
          determining that the Partnership should be dissolved; or
              
                                     A-32

 
               (c) subject to Section 14.4 below, the entry of a final judgment,
          order or decree of a court of competent jurisdiction adjudicating as
          bankrupt either the Partnership or the General Partner, and the
          expiration without appeal of the period, if any, allowed by applicable
          law to appeal therefrom.

          14.2  Method of Liquidation.  Upon the happening of any of the
     events specified in Section 14.1 above, the General Partner (or if there be
     no General Partner, a liquidating trustee selected by those Limited
     Partners holding in the aggregate more than fifty percent 50% of the
     Percentage Interests held by all Limited Partners) shall immediately
     commence to wind up the Partnership's affairs and shall liquidate the
     assets of the Partnership as promptly as possible, unless the General
     Partner, or the liquidating trustee, shall determine that an immediate sale
     of Partnership assets would cause undue loss to the Partnership, in which
     event the liquidation may be deferred for a reasonable time.  The Partners
     shall continue to share Operating Cash Flow, Capital Cash Flow, Profits and
     Losses during the period of liquidation in the same proportions as before
     dissolution (subject to Section 14.2(C) below).  The proceeds from
     liquidation of the Partnership, including repayment of any debts of
     Partners to the Partnership, shall be applied in the order of priority as
     follows:

               A.  Debts of the Partnership, including repayment of principal
          and interest on loans and advances made by the General Partner
          pursuant to Sections 3.3 and/or 9.7 above; then

               B.  To the establishment of any reserves deemed necessary or
          appropriate by the General Partner, or by the person(s) winding up the
          affairs of the Partnership in the event there is no remaining General
          Partner of the Partnership, for any contingent or unforeseen
          liabilities or obligations of the Partnership.  Such reserves
          established hereunder shall be held for the purpose of paying any such
          contingent or unforeseen liabilities or obligations and, at the
          expiration of such period as the General Partner, or such person(s)
          deems advisable, the balance of such reserves shall be distributed in
          the manner provided hereinafter in this Section 14.2 as though such
          reserves had been distributed contemporaneously with the other funds
          distributed hereunder; then

               C.  To the Partners in accordance with their respective Capital
          Account balances, after giving effect to all contributions,
          distributions and allocations for all periods.  In connection
          therewith, the Company, as the holder of Preference Units, shall be
          allocated gross income to the extent necessary to cause its Capital
          Account balance to equal the amount established in the applicable
          Other Securities Term Sheet upon any voluntary or involuntary
          dissolution, liquidation or winding up of the Partnership; provided,
          that no such gross income allocation shall be made to the Company to
          the extent that such allocation would result in any additional Loss
          (or item thereof) being allocated to any Obligated Partner.

          14.3  Date of Termination.  The Partnership shall be terminated when
     all notes received in connection with such disposition have been paid and
     all of the cash or property 
                  
                                     A-33

 
available for application and distribution under Section 14.2 above (including
reserves) shall have been applied and distributed in accordance therewith.

          14.4  Reconstitution Upon Bankruptcy.

               A.  Notwithstanding any dissolution of the Partnership under
          clause (c) of  Section 14.1 above, if the Partnership is reconstituted
          as set forth in this Section 14.4, then the business of the
          Partnership shall be continued with the Partnership's property and the
          Partnership's assets shall not be liquidated.

               B.  If the Partnership is dissolved by reason of the bankruptcy
          of the General Partner, a successor general partner may be admitted
          within 90 days after the dissolution, effective as of the date of
          dissolution, as the General Partner hereunder, with the written
          consent of those Limited Partners holding more than 50% of the
          aggregate Percentage Interests of all Limited Partners.  Upon the
          admission of such successor general partner, without any further
          consent or approval of any other Partner, the Partnership shall be
          reconstituted as a successor limited partnership.

               C.  If the Partnership is dissolved by reason of the bankruptcy
          of the Partnership in a proceeding for the reorganization (and not the
          liquidation) of the Partnership, then, with the consent of the Company
          and those Limited Partners holding at least fifty percent (50%) of the
          Percentage Interests held by all Limited Partners, the Partnership may
          be reconstituted within 90 days after dissolution, effective as of the
          date of dissolution, whereupon the Partnership shall be reconstituted
          as a successor limited partnership.

               D.  The successor limited partnership reconstituted in accordance
          with the foregoing provisions of this Section 14.4 shall continue the
          business of the Partnership with the Partnership's property.  The
          Percentage Interests of the Partners in the successor limited
          partnership shall be in proportion to their respective Percentage
          Interests in the dissolved Partnership.  Such successor limited
          partnership shall be governed by the terms and provisions of this
          Agreement and references in this Agreement to the Partnership or to
          the Partners or their rights and obligations shall be understood to
          comprehend such successor limited partnership and the Partners thereof
          and their rights and obligations.

          14.5  Death, Legal Incompetency, Etc. of a Limited Partner.  The
     death, legal incompetency, insolvency, dissolution or bankruptcy of a
     Limited Partner shall not dissolve or terminate the Partnership.  Upon the
     death or incapacity of an individual Limited Partner, such individual
     Limited Partner's interest in the Partnership shall be transferred either
     by will, the laws of intestacy or otherwise to the legal representative or
     successor of such individual Limited Partner.

     15.  Power of Attorney.  Each Limited Partner hereby irrevocably
constitutes and appoints the Chairman of the Board of the General Partner (or
the Co-Chairmen acting together if there be 
                   
                                     A-34

 
more than one), with full power of substitution, its true and lawful attorney,
for him and in his name, place and stead and for his use and benefit, to sign,
swear to, acknowledge, file and record:

          (i) this Agreement, and subject to Section 16 below, amendments to
     this Agreement;

          (ii) any certificates, instruments and documents (including assumed
     and fictitious name certificates) as may be required by, or may be
     appropriate under, the laws of the State of Illinois or any other State or
     jurisdiction in which the Partnership is doing or intends to do business,
     in order to discharge the purposes of the Partnership or otherwise in
     connection with the use of the name or names used by the Partnership;

          (iii)  any other instrument which may be required to be filed or
     recorded by the Partnership on behalf of the Partners under the laws of any
     State or by any governmental agency in order for the Partnership to conduct
     its business;

          (iv) any documents which may be required to effect the continuation of
     the Partnership, the admission of a substitute or additional Partner, or
     the dissolution and termination of the Partnership, provided such
     continuation, admission or dissolution and termination is not in violation
     of any provision of this Agreement; and

          (v) any documents which may be required or desirable to have the
     General Partner appointed, and act as, the "Tax Matters Partner" as
     described in the Code.

The foregoing grant of authority is a special power of attorney coupled with an
interest, is irrevocable and shall survive the death or incapacity of any
individual Limited Partner, and shall survive the delivery of any assignment by
a Limited Partner of the whole or any portion of his interest in the
Partnership.

     16.  Amendment of Agreement.

          A.  Each Limited Partner, by his execution of or joinder in this
     Agreement, hereby irrevocably appoints the Chairman of the Board of the
     General Partner (or the Co-Chairmen acting together if there be more than
     one) with power of substitution, as his true and lawful attorney coupled
     with an interest, in his name, place and stead to amend this Agreement in
     any respect other than:

               (i) to enlarge the obligation of any Partner to make
          contributions to the capital of the Partnership, as provided for in
          Section 3 above; or

               (ii) except as otherwise provided for in this Agreement or as
          required by law, to modify the allocation of Profits or Losses or
          distributions among the Partners as provided for in Section 7 and 8
          above, respectively; or

               (iii)  to amend Sections 1, 3.2, 9.2, or 12; or
                 
                                     A-35

 
              (iv)  to amend this Section 16.

          B.  With respect to amendments regarding Sections 16(A)(ii) or
     16(A)(iii), this Agreement may be amended with the written consent of the
     Company, the Zell Partners, and the Starwood Partners or their respective
     successors in interest, as applicable, so long as they shall remain
     Partners and those Limited Partners holding not less than 67% of the
     aggregate of Percentage Interests held by all Limited Partners.

          Notwithstanding the foregoing, the terms and conditions of a
     particular series of Preference Units may not be changed without the
     written consent of the holders of at least 67% of the Preference Units
     within the class or series (or such greater percentage as may be provided
     for in the applicable Preference Unit Term Sheet or Other Securities Term
     Sheet, as the case may be).

          C.  With respect to amendments regarding Sections 16(A)(i) or (iv),
     this Agreement may be amended only with the written consent of all
     Partners.

          In the event this Agreement shall be amended pursuant to this Section
     16, the General Partner shall cause this Agreement to be amended to reflect
     the amendment.

     17.  Miscellaneous.

          17.2  Modifications.  Except as otherwise provided in this
     Agreement, no change or modification of this Agreement, nor any waiver of
     any term or condition in the future, shall be valid or binding upon the
     Partners unless such change or modification shall be in writing and signed
     by all of the Partners or, in the case of a waiver of any term or
     condition, such waiver shall be in writing and signed by all Partners who
     were intended, as determined in the

     to which his predecessor-in-interest was subject or bound, without regard
     to whether such a person has executed a counterpart hereof or any other

     rights or obligations greater than those set forth in this Agreement, and
     no person shall acquire an interest in the Partnership or become a Partner

     Partners  and their respective successors, assigns, heirs, legal
     representatives, executors and administrators.  Notwithstanding the
     foregoing, the special voting and consent privileges granted to the Zell
     Partners and the Starwood Partners contained in Section 3.2(B)(e) and
     Article 16 shall be limited to the Zell Partners and the Starwood Partners
     for such time as they remain Partners and any Person acquiring Units as a
     result of the exercise of remedies by a pledgee of Units held by such
     Partner and shall not be transferred to each Partners' respective
     successor-in-interest.

          17.4  Duplicate Originals.  For the convenience of the Partners, any
     number of counterparts hereof may be executed, and each such counterpart
     shall be deemed to be an original instrument, and all of which taken
     together shall constitute one agreement.

          17.5  Construction.  The titles of the Sections and subsections
     herein have been inserted as a matter of convenience of reference only and
     shall not control or affect the meaning or construction of any of the terms
     or provisions herein.

          17.6  Governing Law.  This Agreement shall be governed by the laws
     of the State of Illinois.  Except to the extent the Act is inconsistent
     with the provisions of this Agreement, the provisions of such Act shall
     apply to the Partnership.

          17.7  Other Instruments. The parties hereto covenant and agree that
     they will execute such other and further instruments and documents as, in
     the opinion of the General Partner, are or may become necessary or
     desirable to effectuate and carry out the Partnership as provided for by
     this Agreement.

          17.8  General Partner with Interest as Limited Partner.  If the
     General Partner ever has an interest as a Limited Partner in the
     Partnership, the General Partner shall, with respect to such interest,
     enjoy all of the rights and be subject to all of the obligations and duties
     of a Limited Partner.

          17.9  Legal Construction.  In case any one or more of the provisions
     contained in this Agreement shall for any reason be held to be invalid,
     illegal or unenforceable in any respect, such invalidity, illegality or
     unenforceability shall not affect any other provision 
                                   
                                     A-37

 
     hereof and this Agreement shall be construed as if such invalid, illegal or
     unenforceable provision had never been contained herein.

          17.10  Gender.  Whenever the context shall so require, all words
     herein in any gender shall be deemed to include the masculine, feminine or
     neuter gender, all singular words shall include the plural, and all plural
     words shall include the singular.

          17.11  Prior Agreements Superseded.  Except for joinders, term sheets
     and/or addendums that have been made or will be made and are deemed to be
     incorporated by reference herein and made a part hereof, this Agreement
     supersedes any prior understandings or written or oral agreements amongst
     the Partners, or any of them, respecting the within subject matter and
     contains the entire understanding amongst the Partners with respect
     thereto.

          17.12  No Third Party Beneficiary.  The terms and provisions of this
     Agreement are for the exclusive use and benefit of General Partner and the
     Limited Partners and shall not inure to the benefit of any other person or
     entity.

          17.13  Purchase for Investment.  Each Partner represents, warrants and
     agrees that it has acquired and continues to hold its interest in the
     Partnership for its own account for investment only and not for the purpose
     of, or with a view toward, the resale or distribution of all or any part
     thereof, nor with a view toward selling or otherwise distributing such
     interest or any part thereof at any particular time or under any
     predetermined circumstances. Each Partner further represents and warrants
     that it is a sophisticated investor, able and accustomed to handling
     sophisticated financial matters for itself, particularly real estate
     investments, and that it has a sufficiently high net worth that it does not
     anticipate a need for the funds it has invested in the Partnership in what
     it understands to be a highly speculative and illiquid investment.

          17.14  Waiver.  No consent or waiver, express or implied, by any
     Partner to or of any breach or default by any other Partner in the
     performance by such other Partner of its obligations hereunder shall be
     deemed or construed to be a consent to or waiver of any other breach or
     default in the performance by such other Partner of the same or any other
     obligations of such Partner hereunder. Failure on the part of any Partner
     to complain of any act or failure to act on the part of any other Partner
     or to declare any other Partner in default, irrespective of how long such
     failure continues, shall not constitute a waiver by such Partner of its
     rights hereunder.

          17.15  Time of Essence.  Time is hereby expressly made of the essence
     with respect to the performance by the parties of their respective
     obligations under this Agreement.

          17.16  Counterparts.  This Agreement may be executed in one or more
     counterparts, which when taken together, shall constitute but one original.

                                      A-38

 
     IN WITNESS WHEREOF, the General Partner (on behalf of itself and as
attorney-in-fact for the Limited Partners pursuant to Section 16 hereof) has
executed this Amendment as of the date first written above.
