    During the period from and including August   , 1998 to but excluding August
  , 1999 (the "Initial Spread Period"), the interest rate on the Notes will be
reset quarterly, and will equal LIBOR plus the applicable Spread. The Spread
during the Initial Spread Period is    %. After the Initial Spread Period, the
character and duration of the interest rate on the Notes will be agreed to by
the Operating Partnership and the Remarketing Underwriter on each applicable
Duration/Mode Determination Date and the Spread will be agreed to by the
Operating Partnership and the Remarketing Underwriter on the corresponding
Spread Determination Date. Interest on the Notes during each Subsequent Spread
Period shall be payable, as applicable, either (i) at a floating interest rate
(such Notes being in the "Floating Rate Mode," and such interest being a
"Floating Rate"), or (ii) at a fixed interest rate (such Notes being in the
"Fixed Rate Mode," and such interest rate being a "Fixed Rate"), in each case as
determined by the Operating Partnership and the Remarketing Underwriter in
accordance with a Remarketing Agreement between the Operating Partnership and
the Remarketing Underwriter (the "Remarketing Agreement"). Capitalized terms
used but not defined on this cover page shall have the meanings ascribed to them
under "Description of the Notes" contained herein.
 
    After the Initial Spread Period, the Spread applicable to each Subsequent
Spread Period will be determined on each subsequent Spread Determination Date
that immediately precedes the beginning of the corresponding Subsequent Spread
Period, pursuant to agreement between the Operating Partnership and the
Remarketing Underwriter (except as otherwise provided below), and the interest
rate mode used for each Subsequent Spread Period may be a Floating Rate Mode or
a Fixed Rate Mode, at the discretion of the Operating Partnership and the
Remarketing Underwriter. If the Operating Partnership and the Remarketing
Underwriter are unable to agree on the Spread, (1) the Subsequent Spread Period
will be one year, (2) the Notes will be reset to the Floating Rate Mode, (3) the
Spread for such Subsequent Spread Period will be the Alternate Spread and (4)
the Notes will be redeemable at the option of the Operating Partnership, in
whole or in part, upon at least five

     THE FOLLOWING INFORMATION CONTAINED IN THIS PROSPECTUS SUPPLEMENT IS 
QUALIFIED IN ITS ENTIRETY BY THE DETAILED INFORMATION APPEARING IN THE 
ACCOMPANYING PROSPECTUS OR INCORPORATED THEREIN BY REFERENCE.  AS USED 
HEREIN, THE "OPERATING PARTNERSHIP" SHALL BE DEEMED TO MEAN THE OPERATING 
PARTNERSHIP AND THOSE ENTITIES OWNED OR CONTROLLED BY IT ON A CONSOLIDATED 
BASIS, UNLESS THE CONTEXT INDICATES OTHERWISE.  AS USED HEREIN, THE TERM 
"COMPANY" INCLUDES EQUITY RESIDENTIAL PROPERTIES TRUST ("EQR") AND THOSE 
ENTITIES OWNED OR CONTROLLED BY IT ON A CONSOLIDATED BASIS (THE 
"SUBSIDIARIES"), AS THE SURVIVOR OF THE MERGERS BETWEEN EQR AND EACH OF 
WELLSFORD RESIDENTIAL PROPERTY TRUST ("WELLSFORD") AND EVANS WITHYCOMBE 
RESIDENTIAL, INC. ("EWR") AND EACH OF EQR, WELLSFORD AND EWR AS PREDECESSORS 
TO THE COMPANY, UNLESS THE CONTEXT INDICATES OTHERWISE.

                             THE OPERATING PARTNERSHIP

     The Notes offered hereby are being issued by the Operating Partnership 
which is managed by its general partner, Equity Residential Properties Trust 
(the "Company").  The Company, one of the largest publicly traded real estate 
investment trusts ("REITs") (based on the aggregate market value of its 
outstanding equity capitalization), is a self-administered and self-managed 
equity REIT.   EQR was organized in March 1993 and commenced operations as a 
publicly traded company on August 18, 1993 upon completion of its initial 
public offering (the "EQR IPO").  EQR was formed to continue the multifamily 
property business objectives and acquisition strategies of certain affiliated 
entities controlled by Mr. Samuel Zell, Chairman of the Board of Trustees of 
the Company. These entities had been engaged in the acquisition, ownership 
and operation of multifamily properties since 1969.  In May 1997, EQR 
completed the acquisition of the multifamily property business of Wellsford 
through the tax-free merger of EQR and Wellsford.  In December 1997, EQR 
completed the acquisition of the multifamily property business of EWR through 
the tax-free merger of EQR and EWR. The Company's senior executives average 
over 24 years of experience in the multifamily property business.

     All of the Company's interests in multifamily properties are held or 
controlled directly or indirectly by, and substantially all of its operations 
relating to multifamily properties are conducted through, the Operating 
Partnership.  The Company controls the Operating Partnership as the sole 
general partner and, as of August 4, 1998, owned approximately 88% of the 
Operating Partnership's outstanding partnership interests.

     The Operating Partnership is the largest owner of multifamily properties 
in the United States (based on the number of apartment units owned and total 
revenues earned).  As of August 4, 1998, the Operating Partnership owned or 
had interests in a portfolio of 568 multifamily properties (individually a 
"Property" and collectively the "Properties") containing 158,711 apartment 
units and managed 9,295 additional units owned by affiliated entities.  Since 
the EQR IPO, at which time the Operating Partnership owned 69 Properties, and 
through August 4, 1998, the Operating Partnership has acquired, directly or 
indirectly, interests in an additional 523 Properties containing 143,469 
units for a total purchase price of approximately $8.2 billion, including the 
assumption of approximately $2.4 billion of mortgage indebtedness and 
unsecured notes.  Since the EQR IPO and through August 4, 1998, the Operating 
Partnership has disposed of 24 of its properties and a portion of one of its 
Properties containing an aggregate of 6,483 units and a vacant land parcel 
for a total sales price of approximately $191.7 million and the release of 
mortgage indebtedness in the amount of approximately $27.5 million.  The 
Operating Partnership's interest in 11 of the Properties at the time of 
acquisition thereof consisted solely of ownership of the debt collateralized 
by such Properties and in 21 of the Properties consisted solely of 
investments in partnership interests and subordinated mortgages 
collateralized by such Properties.  As of August 4, 1998, the Properties had 
an average occupancy rate of approximately 96%.  The Properties are located 
throughout the United States in the following 35 states: Alabama, Arizona, 
Arkansas, California, Colorado, Connecticut, Florida, Georgia, Idaho, 
Illinois, Indiana, Iowa, Kansas, Kentucky, Maine, Maryland, Massachusetts, 
Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New Mexico, Nevada, 
North Carolina, Ohio, Oklahoma, Oregon, South Carolina, Tennessee, Texas, 
Utah, Virginia, Washington and Wisconsin.  

     The Operating Partnership's executive offices are located at Two North 
Riverside Plaza, Suite 400, Chicago, Illinois 60606, and its telephone number 
is (312) 474-1300.  In addition, the Operating Partnership has 30 management 
offices in the following cities: Chicago, Illinois; Denver, Colorado; 
Seattle, Tukwila and Redmond, Washington; Bethesda, Maryland; Atlanta, 
Georgia; Las Vegas, Nevada; Scottsdale and Tucson, Arizona; Portland, Oregon;

                                RECENT DEVELOPMENTS

MERGER ACTIVITY 

     On July 8, 1998, EQR entered into an Agreement and Plan of Merger 
regarding the planned acquisition of the multifamily property business of 
Merry Land & Investment Company, Inc. ("Merry Land"), a Georgia corporation, 
through the tax free merger of EQR and Merry Land (the "Merger").  The 
transaction is valued at approximately $2.2 billion and includes 118 
multifamily properties containing 34,990 units.  In the Merger, each 
outstanding share of common stock of Merry Land will be converted to .53 of a 
common share of EQR.  The Merger is subject to approval of the shareholders 
of EQR and Merry Land and, therefore, completion of the Merger is conditioned 
upon such approval and certain other closing conditions.  Upon completion of 
the Merger, it is expected that EQR will contribute the assets of Merry Land 
to the Operating Partnership in exchange for additional partnership interests 
in the Operating Partnership.

     Merry Land is subject to the informational requirements of the 
Securities Exchange Act of 1934, as amended ("Exchange Act"), and, in 
accordance therewith, files reports, proxy statements and other information 
with the Securities and Exchange Commission (the "Commission"), including 
Merry Land's Annual Report on Form 10-K for the year ended December 31, 1997. 
Reports, proxy statements and other information filed by Merry Land can be 
inspected and copied at the public reference facilities maintained by the 
Commission at 450 Fifth Street, N.W., Washington, D.C.  20549; and at its 
Regional Offices located at 500 West Madison Street, Suite 1400, Chicago, 
Illinois  60661; and Seven World Trade Center, Suite 1300, New York, New York 
10048.  Copies of such material can be obtained from the Public Reference 
Section of the Commission, 450 Fifth Street, N.W., Washington, D.C. 20549, at 
prescribed rates.  The Commission maintains a web site that contains reports, 
proxy and information statements and other information regarding registrants 
that file electronically with the Commission. The address of the Commission's 
web site is:  http://www.sec.gov.  The shares of common stock of Merry Land 
are currently listed on the New York Stock Exchange ("NYSE") and such 
reports, proxy statements and other information concerning Merry Land can be 
inspected at the offices of NYSE, 20 Broad Street, New York, New York  10005.

ACQUISITIONS

     From January 1, 1998 through August 4, 1998, the Operating Partnership 
acquired 90 Properties containing an aggregate of 21,063 units at a total 
purchase price of approximately $1.5 billion (including the assumption of 
mortgage indebtedness of approximately $410.6 million).  The Operating 
Partnership funded the cash portion of these acquisitions primarily with 
proceeds from previous securities issuances by the Company, its Line of 
Credit and working capital.  See "Securities Issuances" below.

PROBABLE ACQUISITIONS

     As of August 4, 1998, the Operating Partnership had entered into 
contracts with unaffiliated sellers to acquire 15 additional properties 
containing 4,070 units which are located in seven states (collectively, the 
"Properties Under Contract").  The total combined purchase price for the 
Properties Under Contract is approximately $252 million, including the 
assumption of approximately $86.2 million of mortgage indebtedness.  There 
can be no assurance that these 15 Properties Under Contract will be acquired 
or, if acquired, that the terms of such acquisitions will not change from the 
terms presently contemplated.  The Operating Partnership anticipates that the 
acquisition of the Properties Under Contract will be funded with its working 
capital and/or its Line of Credit.  The Operating Partnership believes that 
the Properties Under Contract can be integrated into its system of management 
offices without any significant corresponding increase in the costs of 
operations of such offices.

PENDING ACQUISITIONS

               ADDITIONAL PROPERTIES UNDER CONTRACT

     As of August 4, 1998, the Operating Partnership had entered into 
contracts with various unaffiliated sellers to acquire two additional 
properties under contract (the "Additional Properties Under Contract") for a 
total combined purchase price of approximately $50.5 million, including the 
assumption of approximately $33.45 million of mortgage indebtedness.  These 
Additional Properties Under Contract contain 806 units and are located in two 
states.  The contracts for the Additional Properties Under Contract contain 
due diligence contingency provisions that allow the Operating Partnership to 
conduct extensive investigative procedures of such properties and give the 
Operating Partnership the option to terminate such contracts with a full 
refund of earnest money if the Operating Partnership becomes dissatisfied 
with the Additional Properties Under Contract in any way, in its sole 
discretion, during such review period. The purchase price for the Additional 
Properties Under Contract is expected to be funded primarily from the 
Operating Partnership's Line of Credit and/or working capital.  There can be 
no 

                                       S-5
<PAGE>

assurance that the Additional Properties Under Contract will be acquired or, 
if acquired, that the terms of such acquisitions will not change from the 
terms presently contemplated.

               PROPERTIES UNDER NEGOTIATION

     As of August 4, 1998, the Operating Partnership was also negotiating 
with various sellers for the acquisition of five additional properties (the 
"Properties Under Negotiation") containing 928 units for a purchase price of 
approximately $53.8 million, including the assumption of approximately $17.9 
million of mortgage indebtedness.  With respect to the Properties Under 
Negotiation, the Operating Partnership was negotiating the significant terms 
of the purchase contracts for such properties.  The Operating Partnership 
anticipates that, if and when entered into, the purchase contracts for the 
Properties Under Negotiation will contain due diligence contingency 
provisions that will allow the Operating Partnership to conduct extensive 
investigations of such properties and will give the Operating Partnership 
flexibility to terminate such contracts with a full refund of earnest money 
if the Operating Partnership becomes dissatisfied with the Properties Under 
Negotiation in any way, in its sole discretion, during such review period.  
If the Operating Partnership acquires the Properties Under Negotiation, it is 
expected that the terms and conditions of such acquisitions will be similar 
to other acquisitions of Properties made by the Operating Partnership.  The 
purchase price for the Properties Under Negotiation is expected to be funded 
primarily with the Operating Partnership's Line of Credit.  In addition, the 
Company or the Operating Partnership may consider issuing additional equity 
or debt securities to finance some or all of such potential acquisitions.  
There can be no assurance, however, that the Properties Under Negotiation 
will be acquired or, if acquired, that the terms of such acquisitions will 
not change from the terms presently contemplated.

DISPOSITIONS

     From January 1, 1998 through August 4, 1998, the Operating Partnership 
disposed of its interests in six properties containing 1,448 units for an 
aggregate sales price of approximately $61.9 million, including the release 
of approximately $7 million of mortgage indebtedness.  The net proceeds of 
these dispositions were or will be used for the acquisition of additional 
properties.

SECURITIES ISSUANCES

     Since January 1, 1998, the Operating Partnership has raised 
approximately $306 million pursuant to one public offering of its Debt 
Securities.  Since January 1, 1998, the Company has raised an aggregate of 
approximately $358 million pursuant to six separate public offerings of EQR's 
common shares of beneficial interest.  In addition, from January 1, 1998, 
through August 4, 1998, the Company has raised approximately $50.1 million 
pursuant to its Distribution Reinvestment and Share Purchase Plan.

<PAGE>

                                  USE OF PROCEEDS

     The net proceeds to the Operating Partnership from the Offering are 
estimated at $                   after the deduction of the underwriting 
discount and the estimated expenses payable by the Operating Partnership.  
The Operating Partnership intends to use the net proceeds of this offering to 
pay down existing indebtedness on its Line of Credit, which bears interest at 
a weighted average rate of 6.05% and matures in November 1999.  As of August 
4, 1998, $360 million was outstanding under the Line of Credit.

                              BUSINESS AND PROPERTIES

     The Operating Partnership is managed by the Company.  The Company is a 
self-administered and self-managed equity REIT.  EQR was established in 1993 
to continue the multifamily property business objectives and acquisition 
strategies of certain affiliated entities controlled by Mr. Zell, Chairman of 
the Board of Trustees of the Company. These entities had been engaged in the 
multifamily property business since 1969.  The Company is a fully integrated 
real estate concern that acquires, improves, operates and manages its 
Properties.  The Operating Partnership has benefited, and expects to benefit, 
from the following elements:

DIVERSIFIED PORTFOLIO

     As of August 4, 1998, the Operating Partnership owned or had interests 
in a portfolio of 568 Properties containing 158,711 apartment units located 
in 35 states.  As of such date, the Operating Partnership was the largest 
owner of multifamily properties in the United States (based on the number of 
apartment units owned and total revenues earned).  The Operating 
Partnership's interest in 11 of the Properties at the time of acquisition 
thereof consisted solely of ownership of the debt collateralized by such 
Properties and in 21 of the Properties consisted solely of investments in 
partnership interests and subordinated mortgages collateralized by such 
Properties.  No single Property represents more than 1.0% of total apartment 
units.  The distribution of the Properties throughout the United States 
reflects the Operating Partnership's belief that geographic diversification 
helps insulate the portfolio from regional and local economic influences.  At 
the same time, the Operating Partnership has sought to create clusters of 
Properties within each of its primary markets to achieve economies of scale 
in management and operation.  The Operating Partnership has 30 management 
offices in the following cities: Chicago, Illinois; Denver, Colorado; 
Seattle, Tukwila and Redmond, Washington; Bethesda, Maryland; Atlanta, 
Georgia; Las Vegas, Nevada; Scottsdale and Tucson, Arizona; Portland, Oregon; 
Dallas, Houston and San Antonio, Texas; Irvine, Pleasant Hill and Stockton, 
California; Ypsilanti, Michigan; Charlotte and Raleigh, North Carolina; 
Tampa, Jacksonville and Ft. Lauderdale, Florida; Kansas City, Kansas; 
Minneapolis, Minnesota; Louisville, Kentucky; Tulsa, Oklahoma; Boston, 
Massachusetts; and Nashville and Memphis, Tennessee.

EXPERIENCED MANAGEMENT

     The Company's senior executives average over 24 years of experience in 
the multifamily property business.  The Operating Partnership has a fully 
integrated management team:  an Acquisitions Department that is dedicated 
exclusively to the property acquisition function and is in constant contact 
with principals and brokers nationwide; an Asset Management Department that 
establishes strategic plans with respect to the portfolio including the 
development and implementation of long-term business plans, asset financings, 
property repositionings, expansions, and property disposition decisions; a 
Property Management Department that aggressively manages the portfolio 
through significant interaction with on-site property managers at each 
Property; an Accounting and Finance Department that maintains the books and 
records of the Properties and generates timely financial reports; a Capital 
Markets Department that manages investor relations and capital raising; and a 
Legal Department that oversees all of the Operating Partnership's legal 
affairs.

SOPHISTICATED MANAGEMENT INFORMATION SYSTEMS

     The Operating Partnership makes extensive use of management information 
systems.  The Operating Partnership has installed on-site computers at every 
Property, except for the newly-acquired Properties at which such computers 
will be installed, that are capable of compiling and forwarding to the 
Operating Partnership's Regional Operations Centers on a daily basis numerous 
standardized reports including daily occupancy, lease expiration and 
renewals, prospective tenants and rental rate information.  Quality controls 
are maintained through the Operating Partnership's practice of (i) conducting 
resident 

                                       S-7
<PAGE>

satisfaction surveys, (ii) surveying residents that move out of the 
Properties, and (iii) surveying prospective tenants who select alternative 
housing.

THE PROPERTIES

     As of August 4, 1998, the Operating Partnership owned or had interests 
in a portfolio of 568 Properties located in 35 states containing 158,711 
apartment units with the largest having 1,420 units and the smallest having 
40 units.  The average number of units per Property was approximately 279.  
The units are typically contained in a series of two-story buildings.  As of 
August 4, 1998, the Properties had an average occupancy rate of approximately 
96%.  Tenant leases are generally year-to-year and require security deposits. 
The Properties typically provide residents with attractive amenities, 
including a clubhouse, swimming pool, laundry facilities and cable television 
access.  Certain Properties offer additional amenities such as saunas, 
whirlpools, spas, sports courts and exercise rooms.

                              DESCRIPTION OF THE NOTES

GENERAL

  The Notes constitute a separate series of securities (which are more fully 
described in the accompanying Prospectus) to be issued pursuant to an 
indenture, dated as of October 1, 1994 (the "Indenture") between the 
Operating Partnership and The First National Bank of Chicago, as trustee (the 
"Trustee").  The terms of the Notes include those provisions contained in the 
Indenture and those made part of the Indenture by reference to the Trust 
Indenture Act of 1939, as amended (the "Trust Indenture Act").  The following 
description of the particular terms of the Notes offered hereby (referred to 
herein as the "Notes" and in the Prospectus as the "Debt Securities") 
supplements, and to the extent inconsistent therewith, replaces, the 
description of the general terms and provisions of the Debt Securities set 
forth in the Prospectus, to which description reference is hereby made.  The 
following summary of the Notes is qualified in its entirety by reference to 
the Indenture referred to in the Prospectus and to the Notes to be issued 
thereunder and to the Remarketing Agreement and the Remarketing Underwriting 
Agreement (the forms of which will be filed, pursuant to a Current Report on 
Form 8-K, as exhibits to the Registration Statement of which this Prospectus 
forms a part).  Capitalized terms used but not defined herein shall have the 
meanings ascribed to them in the Prospectus or the Indenture, as the case may 
be. 

     The Notes will be limited to $150,000,000 in aggregate 
principal amount and will mature, unless previously redeemed, on August     , 
2003.  The Notes will be direct, unsecured obligations of the Operating 
Partnership and will rank equally with each other and with all other 
unsecured and unsubordinated indebtedness of the Operating Partnership from 
time to time.  The Notes will be effectively subordinated to the prior claims 
of each secured mortgage lender to any specific Property which secures such 
lender's mortgage.  As of June 30, 1998, such mortgages aggregated 
approximately $1.8 billion.  As of June 30, 1998, the outstanding 
indebtedness of the Operating Partnership with which the Notes will rank 
equally was approximately $1.4 billion (net of a $4.1 million discount and 
including a $7.4 million premium).  As of June 30, 1998, the Operating 
Partnership's total debt was approximately $3.4 billion, and on a pro forma 
basis giving effect to this Offering, the total outstanding indebtedness of 
the Operating Partnership was approximately $3.5 billion.  Subject to certain 
limitations set forth in the Indenture, and as described under "Description 
of Debt Securities--Certain Covenants--Limitations on Incurrence of 
Indebtedness" and "--Additional Covenants and/or Modifications to the 
Covenants Described Above" in the accompanying Prospectus, the Indenture 
permits the Operating Partnership to incur additional secured and unsecured 
indebtedness.

     The Notes will be issued only in fully registered, book-entry form.  See 
"--Book-Entry System" below.

     The Notes will not be subject to a sinking fund.

CERTAIN COVENANTS

     Reference is made to the sections entitled "Description of Debt 
Securities -- Certain Covenants" and "-- Additional Covenants and/or 
Modifications to the Covenants Described Above" in the accompanying 
Prospectus for a description of the covenants applicable to the Notes.  
Compliance with such covenants with respect to the Notes generally may not be 
waived by the Board of Trustees of the Company, as general partner of the 
Operating Partnership, or the Trustee unless the Holders of at least a 
majority in principal amount of all outstanding Notes of such series consent 
to such waiver.

FLOATING RATE MODE

     During the period from and including August    , 1998 to but excluding 
August    , 1999 (the "Initial Spread Period"), interest on the Notes will be 
payable quarterly in arrears, on November    , 1998, February    , 1999, May  
 , 1999 and August    , 1999 (or, if not a Business Day (as defined below), 
on the next succeeding Business Day (except as described below)), to the 
persons in whose names the Notes are registered at the close of business on 
the applicable record date (in the case of Notes in either the Floating Rate 
Mode or the Fixed Rate Mode, the 15th calendar day, whether or not a Business 
Day, next preceding the applicable Interest Payment Date) next preceding such 
Interest Payment Date. During the Initial Spread Period and any Subsequent 
Spread Period during which the Notes are in the Floating Rate Mode, the 
interest rate on the Notes will be reset quarterly and the Notes will bear 
interest at a per annum rate (computed on the basis of the actual number of 
days elapsed over a 360-day year) equal to LIBOR (as defined below) for the 
applicable Quarterly Period (as defined below), plus the applicable Spread 
(as defined below).  Interest on the Notes will accrue from and including 
each Interest Payment Date (or in the case of the Initial Quarterly Period 
(as defined below), August    , 1998) to but excluding the next succeeding 
Interest Payment Date or maturity date, as the case may be. The Initial 
Quarterly Period will be the period 

                                       S-12
<PAGE>

from and including August     , 1998 to but excluding the first Interest 
Payment Date (November    , 1998) (the "Initial Quarterly Period").  
Thereafter, each Quarterly Period during the Initial Spread Period or any 
Subsequent Spread Period (as defined below) (each, a "Quarterly Period") will 
be from and including the most recent Interest Payment Date to which interest 
has been paid to but excluding the next Interest Payment Date; the first day 
of a Quarterly Period is referred to herein as an "Interest Reset Date."

     The Spread applicable during the Initial Spread Period will be       % 
(the "Initial Spread"), and the interest rate mode used for the Initial 
Spread Period will be the Floating Rate Mode.  Thus, the interest rate per 
annum during the Initial Quarterly Period will be equal to LIBOR, determined 
as of August     , 1998, plus      %.  The interest rate per annum for each 
succeeding Quarterly Period during the Initial Spread Period will equal LIBOR 
for such Quarterly Period plus the Initial Spread.  Thereafter, the Spread 
will be determined in the manner described below for each subsequent Spread 
period from and including each Commencement Date to but excluding each next 
succeeding Commencement Date (a "Subsequent Spread Period"), which will be 
one or more periods of at least six months and not more than ten years (or 
any integral-multiple of six months therein), designated by the Operating 
Partnership, commencing on a February    or August     (or as otherwise 
specified by the Operating Partnership and the Remarketing Underwriter (as 
defined below) on the applicable Duration/Mode Determination Date (as defined 
below) in connection with the establishment of each Subsequent Spread 
Period), as applicable (a "Commencement Date"), through and including August  
  , 2003 (no Subsequent Spread Period may end after August    , 2003).  The 
first Commencement Date will be August     , 1999.

     If any Interest Payment Date (other than at maturity), redemption date, 
Interest Reset Date, Commencement Date or Tender Date (as defined below) 
would otherwise be a day that is not a Business Day, such Interest Payment 
Date, redemption date, Interest Reset Date, Commencement Date or Tender Date 
will be postponed to the next succeeding day that is a Business Day, except 
that if such Business Day is in the next succeeding calendar month, such 
Interest Payment Date, redemption date, Interest Reset Date, Commencement 
Date or Tender Date shall be the next preceding Business Day.

     LIBOR applicable for a Quarterly Period will be determined by the Rate 
Agent (as defined under "--Tender at Option of Beneficial Owners" below) as 
of the second London Business Day (as defined below) preceding each Interest 
Reset Date (the "LIBOR Determination Date") in accordance with the following 
provisions:

          (i)  LIBOR will be determined on the basis of the offered rates for
     three-month deposits in U.S. dollars, commencing on the second London
     Business Day immediately following such LIBOR Determination Date, which
     appears on Telerate Page 3750 (as defined below) as of approximately
     11:00 a.m., London time, on such LIBOR Determination Date.  "Telerate
     Page 3750" means the display designated on page "3750" on Dow Jones Markets
     Limited (or such other page as may replace the 3750 page on that service,
     any successor service or such other service or services as may be nominated
     by the British Bankers' Association for the purpose of displaying London
     interbank offered rates for U.S. dollar deposits).  If no rate appears on
     Telerate Page 3750, LIBOR for such LIBOR Determination Date will be
     determined in accordance with the provisions of paragraph (ii) below.

          (ii) With respect to a LIBOR Determination Date on which no rate
     appears on Telerate Page 3750 as of approximately 11:00 a.m., London time,
     on such LIBOR Determination Date, the Rate Agent shall request the
     principal London offices of each of four major reference banks in the
     London interbank market selected by the Rate Agent to provide the Rate
     Agent with a quotation of the rate at which three-month deposits in U.S.
     dollars, commencing on the second London Business Day immediately following
     such LIBOR Determination Date, are offered by it to prime banks in the
     London interbank market as of approximately 11:00 a.m., London time, on
     such LIBOR Determination Date in a principal amount equal to an amount of
     not less than U.S. $1,000,000 that is representative for a single
     transaction in such market at such time.  If at least two such quotations
     are provided, LIBOR for such LIBOR Determination Date will be the
     arithmetic mean of such quotations as calculated by the Rate Agent.  If
     fewer than two quotations are provided, LIBOR for such LIBOR Determination
     Date will be the arithmetic mean of the rates quoted as of approximately
     11:00 a.m., New York City time, on such LIBOR Determination Date by three
     major banks in The City of New York selected by the Rate Agent (after
     consultation with the Operating Partnership) for loans in U.S. dollars to
     leading European banks, having a three-month maturity commencing on the
     second London Business Day immediately following such LIBOR Determination
     Date and in a principal amount equal to an amount of not less than U.S.
     $1,000,000 that is representative for a single transaction in such market
     at such time; provided, however, that if the banks selected as aforesaid by
     the Rate Agent are not quoting as mentioned in this sentence, LIBOR for
     such LIBOR Determination Date will be LIBOR determined with respect to the
     immediately preceding LIBOR Determination Date, or in the case of the first
     LIBOR Determination Date, LIBOR for the Initial Quarterly Period.

FIXED RATE MODE

     If the Notes are to be reset to the Fixed Rate Mode, as agreed to by the 
Operating Partnership and the Remarketing Underwriter on a Duration/Mode 
Determination Date, then the applicable Fixed Rate for the corresponding 
Subsequent Spread Period will be determined by 1:00 p.m., New York City time, 
on the third Business Day prior to the Commencement Date for such Subsequent 
Spread Period (the "Fixed Rate Determination Date"), in accordance with the 
following provisions: the Fixed Rate will be determined by adding (i) the 
applicable Spread (as agreed to by the Operating Partnership and the 
Remarketing Underwriter on the preceding Spread Determination Date (as 
defined below)) to (ii) the yield to maturity determined by 1:00 p.m., New 
York City time, on the Fixed Rate Determination Date (expressed as a bond 
equivalent, on the basis of a year of 365 or 366 days, as applicable, and 
applied on a daily basis) of the applicable United States Treasury security, 
selected by the Rate Agent after consultation with the Remarketing 
Underwriter, as having a maturity comparable to the duration selected for the 
following Subsequent Spread Period, which would be used in accordance with 
customary financial practice in pricing new issues of corporate debt 
securities of comparable maturity to the duration selected for the following 
Subsequent Spread Period.

     Interest in the Fixed Rate Mode will be computed on the basis of a 
360-day year of twelve 30-day months. Such interest will be payable 
semiannually in arrears on the Interest Payment Dates (February     and 
August    , unless otherwise specified by the Operating Partnership and the 
Remarketing Underwriter on the applicable Duration/Mode Determination Date) 
at the applicable Fixed Rate, as determined by the Operating Partnership and 
the Remarketing Underwriter on the Fixed Rate Determination Date, beginning 
on the Commencement Date and for the duration of the relevant Subsequent 
Spread Period. Interest on the Notes will accrue from and including each 
Interest Payment Date to but excluding the next succeeding Interest Payment 
Date or maturity date, as the case may be.  See "--Additional Terms of the 
Notes" below for other provisions applicable to Notes in the Fixed Rate Mode.

     If any Interest Payment Date or any redemption date in the Fixed Rate 
Mode falls on a day that is not a Business Day (in either case, other than 
any Interest Payment Date or redemption date that falls on a Commencement 
Date, in which case such date will be postponed to the next day that is a 
Business Day), the related payment of principal and interest will be made on 
the next succeeding Business Day as if it were made on the date such payment 
was due, and no interest will accrue on the amounts so payable for the period 
from and after such dates.

ADDITIONAL TERMS OF THE NOTES

     The Spread that will be applicable during each Subsequent Spread Period 
will be the percentage (a) recommended by the Remarketing Underwriter (as 
defined under "--Tender at Option of Beneficial Owners" below) so as to 
result in a rate that, in the opinion of the Remarketing Underwriter, will 
enable tendered Notes to be remarketed by the Remarketing Underwriter at 100% 
of the principal amount thereof, as described under "--Tender at Option of 
Beneficial Owners" below, and (b) agreed to by the Operating Partnership. The 
interest rate mode during each Subsequent Spread Period shall be either the 
Floating Rate Mode or the Fixed Rate Mode, as determined by the Operating 
Partnership and the Remarketing Underwriter.

     If the maturity date for the Notes falls on a day that is not a Business 
Day, the related payment of principal and interest will be made on the next 
succeeding Business Day as if it were made on the date such payment was due, 
and no interest will accrue on the amounts so payable for the period from and 
after such date.

     Unless notice of redemption of the Notes as a whole has been given, the 
duration, redemption dates, redemption type (I.E., par, premium or 
make-whole), redemption prices (if applicable), Commencement Date, Interest 
Payment Dates, interest rate mode (I.E., Fixed Rate Mode or Floating Rate 
Mode) and any other relevant terms for each Subsequent Spread Period will be 
established by 3:00 p.m., New York City time, on the tenth Business Day prior 
to the Commencement Date of each Subsequent Spread Period (the "Duration/Mode 
Determination Date"). In addition, the Spread for each Subsequent Spread 
Period will be established by 1:00 p.m., New York City time, on the fifth 
Business Day prior to the Commencement Date of such Subsequent Spread Period 
(the "Spread Determination Date"). The Operating Partnership will request not 
less than five nor more than ten Business Days prior to any Spread 
Determination Date, that DTC notify its Participants (as defined below) of 
such Spread Determination Date and of the procedures that must be followed if 
any beneficial owner of a Note wishes to tender such Note as described under 
"--Tender at Option of Beneficial Owners" below. In the event that DTC or its 
nominee is no longer the holder of record of the Notes, the Operating 
Partnership will notify the holders of Notes of such information within such 
period of time.  This will be the only notice given by the Operating 
Partnership or the Remarketing Underwriter with respect to such Spread 
Determination Date and procedures for tendering Notes.  The term "Business 
Day" means any day other than a Saturday or Sunday or a day on which banking 
institutions in The City of New York are required or 

                                       S-14
<PAGE>

authorized to close and, in the case of Notes in the Floating Rate Mode, that 
is also a London Business Day. The term "London Business Day" means any day 
on which dealings in deposits in U.S. dollars are transacted in the London 
interbank market.

     In the event that the Operating Partnership and the Remarketing 
Underwriter do not agree on the Spread for any Subsequent Spread Period, then 
(1) the Subsequent Spread Period will be one year, (2) the Notes will be 
reset to the Floating Rate Mode, (3) the Spread for such Subsequent Spread 
Period will be the Alternate Spread (as defined below) and (4) the Notes will 
be redeemable at the option of the Operating Partnership, in whole or in 
part, upon at least five Business Days' notice given by no later than the 
fifth Business Day after the Spread Determination Date in the manner 
described under "--Redemption of the Notes" below, at a redemption price 
equal to 100% of the principal amount thereof, together with accrued interest 
to the redemption date, except that Notes may not be redeemed prior to the 
Tender Date or later than the last day of such one-year Subsequent Spread 
Period.  The Alternate Spread will be the percentage equal to LIBOR 
(determined as described above) for the Quarterly Period beginning on the 
Commencement Date for such Subsequent Spread Period.

     All percentages resulting from any calculation of any interest rate for 
the Notes will be rounded, if necessary, to the nearest one hundred 
thousandth of a percentage point, with five one millionths of a percentage 
point rounded upward and all dollar amounts will be rounded to the nearest 
cent, with one-half cent being rounded upward.

TENDER AT OPTION OF BENEFICIAL OWNERS

     In the event the Operating Partnership and the Remarketing Underwriter 
agree on the Spread on the Spread Determination Date with respect to any 
Subsequent Spread Period, the Operating Partnership and the Remarketing 
Underwriter will enter into a Remarketing Underwriting Agreement (the 
"Remarketing Underwriting Agreement") on such Spread Determination Date, 
under which the Remarketing Underwriter will agree, subject to the terms and 
conditions set forth therein, to purchase from tendering holders of Notes on 
the date immediately following the end of such Subsequent Spread Period (the 
"Tender Date") all Notes with respect to which the Remarketing Underwriter 
receives a Tender Notice as described below at 100% of the principal amount 
thereof (the "Purchase Price").  In such event (except as otherwise provided 
in the next succeeding paragraph), each beneficial owner of a Note may, at 
such owner's option, upon giving notice as provided below (the "Tender 
Notice"), tender such Note for purchase by the Remarketing Underwriter on the 
Tender Date at the Purchase Price.  The Purchase Price will be paid by the 
Remarketing Underwriter in accordance with the standard procedures of DTC, 
which currently provide for payments in same-day funds.  Interest accrued on 
the Notes with respect to the preceding interest period will be paid by the 
Operating Partnership in the manner described under "--Book-Entry System" 
below and "--Additional Terms of the Notes" above.  If such beneficial owner 
has an account at the Remarketing Underwriter and tenders such Note through 
such account, such beneficial owner will not be required to pay any fee or 
commission to the Remarketing Underwriter.  If such Note is tendered through 
a broker, dealer, commercial bank, trust company or other institution, other 
than the Remarketing Underwriter, such holder may be required to pay fees or 
commissions to such other institution.  It is currently anticipated that 
Notes so purchased by the Remarketing Underwriter will be remarketed by it.

     The Tender Notice must be received by the Remarketing Underwriter during 
the period commencing at 3:00 p.m., New York City time, on the Spread 
Determination Date and ending at 12:00 noon, New York City time, on the 
second Business Day following such Spread Determination Date for such 
Subsequent Spread Period (the "Notice Date").  In order to ensure that a 
Tender Notice is received on a particular day, the beneficial owner of Notes 
must direct his broker or other designated Participant or Indirect 
Participant to give such Tender Notice before the broker's cut-off time for 
accepting instructions for that day. Different firms may have different 
cut-off times for accepting instructions from their customers.  Accordingly, 
beneficial owners should consult the brokers or other Participants or 
Indirect Participants through which they own their interests in the Notes for 
the cut-off times for such brokers, other Participants or Indirect 
Participants. See "--Book-Entry System" below.  Except as otherwise provided 
below, a Tender Notice shall be irrevocable.  If a Tender Notice is not 
received for any reason by the Remarketing Underwriter with respect to any 
Note by 5:00 p.m., New York City time, on the Notice Date, the beneficial 
owner of such Note shall be deemed to have elected not to tender such Note 
for purchase by the Remarketing Underwriter.

     The Remarketing Underwriter will attempt, on a reasonable best efforts 
basis, to remarket the tendered Notes at a price equal to 100% of the 
aggregate principal amount so tendered.  There is no assurance that the 
Remarketing Underwriter will be able to remarket the entire principal amount 
of Notes tendered in a remarketing.  The obligation of the Remarketing 
Underwriter to purchase Notes from tendering holders of Notes will be subject 
to several conditions precedent set forth in the Remarketing Underwriting 
Agreement that are customary in the Operating Partnership's public offerings, 
including a condition that no material adverse change in the condition of the 
Operating Partnership and its subsidiaries, taken as a whole, 

                                       S-15
<PAGE>

shall have occurred since the Spread Determination Date.  In addition, the 
Remarketing Underwriting Agreement will provide for the termination thereof 
by the Remarketing Underwriter upon the occurrence of certain events that are 
also customary in the Operating Partnership's public securities offerings.  
In the event that, due to such events with respect to any Subsequent Spread 
Period, the Remarketing Underwriter does not purchase on the relevant Tender 
Date all of the Notes for which a Tender Notice shall have been given, (1) 
all such Tender Notices will be null and void, (2) none of the Notes for 
which such Tender Notices shall have been given will be purchased by the 
Remarketing Underwriter on such Tender Date, (3) the Subsequent Spread Period 
will be one year, which Subsequent Spread Period shall be deemed to have 
commenced upon the applicable Commencement Date, (4) the Notes will be reset 
to the Floating Rate Mode, (5) the Spread for such Subsequent Spread Period 
will be the Alternate Spread and (6) the Notes will be redeemable at the 
option of the Operating Partnership, in whole or in part, upon at least ten 
Business Days' notice given by no later than the fifth Business Day following 
the relevant Tender Date in the manner described under "--Redemption of the 
Notes" below, on the date set forth in such notice, which shall be no later 
than the last day of such one-year Subsequent Spread Period, at a redemption 
price equal to 100% of the principal amount thereof, together with accrued 
interest to the redemption date.

     No beneficial owner of any Note shall have any rights or claims against 
the Operating Partnership or the Remarketing Underwriter as a result of the 
Remarketing Underwriter not purchasing such Notes, except that such 
beneficial owner shall have the right to receive the Alternate Spread on such 
Notes from the Operating Partnership.  The Operating Partnership will have no 
obligation under any circumstance to repurchase any Notes, except in the case 
of Notes called for redemption as described below.

     If the Remarketing Underwriter does not purchase all Notes tendered for 
purchase on any Tender Date, it will promptly notify the Operating 
Partnership and the Trustee.  As soon as practicable after receipt of such 
notice, the Operating Partnership will cause a notice to be given to holders 
of Notes specifying (1) the one-year duration of the Subsequent Spread 
Period, (2) that the Notes will be reset to the Floating Rate Mode, (3) the 
Spread for such Subsequent Spread Period (which shall be the Alternate 
Spread) and (4) LIBOR for the initial Quarterly Period of such Subsequent 
Spread Period.

     The term "Remarketing Underwriter" means the nationally recognized 
broker-dealer selected by the Operating Partnership to act as Remarketing 
Underwriter.  The term "Rate Agent" means the entity selected by the 
Operating Partnership as its agent to determine (i) LIBOR and the interest 
rate on the Notes for any Quarterly Period and/or (ii) the yield to maturity 
on the applicable United States Treasury security that is used in connection 
with the determination of the applicable Fixed Rate, and the ensuing 
applicable Fixed Rate.  Pursuant to the Remarketing Agreement, Merrill Lynch, 
Pierce, Fenner & Smith Incorporated has agreed to act as Remarketing 
Underwriter and Rate Agent. The Operating Partnership, in its sole 
discretion, may change the Remarketing Underwriter and the Rate Agent for any 
Subsequent Spread Period at any time on or prior to 3:00 p.m., New York City 
time, on the Duration/Mode Determination Date relating thereto.

     Each of the Rate Agent and the Remarketing Underwriter, in its 
individual or any other capacity, may buy, sell, hold and deal in any of the 
Notes.  Either of such parties may exercise any vote or join in any action 
which any beneficial owner of Notes may be entitled to exercise or take with 
like effect as if it did not act in any capacity under the Remarketing 
Agreement.  Either of such parties, in its individual capacity, either as 
principal or agent, may also engage in or have an interest in any financial 
or other transaction with the Operating Partnership as freely as if it did 
not act in any capacity under the Remarketing Agreement.

REDEMPTION OF THE NOTES

     The Notes may not be redeemed prior to August     , 1999.  On that date, 
on each Commencement Date and on those Interest Payment Dates specified as 
redemption dates by the Operating Partnership on the Duration/Mode 
Determination Date in connection with any Subsequent Spread Period, the Notes 
may be redeemed, at the option of the Operating Partnership, in whole or in 
part, upon notice thereof given at any time during the 30 calendar day period 
ending on the tenth Business Day prior to the redemption date, in accordance 
with the redemption type selected on the Duration/Mode Determination Date.  
In the event that less than all of the outstanding Notes are to be redeemed, 
the Notes to be redeemed shall be selected by such method as the Operating 
Partnership shall deem fair and appropriate.  So long as the Global Note is 
held by DTC, the Operating Partnership will give notice to DTC, whose nominee 
is the record holder of all of the Notes, and DTC will determine the 
principal amount to be redeemed from the account of each Participant.  A 
Participant may determine to redeem from some beneficial owners (which may 
include a Participant holding Notes for its own account) without redeeming 
from the accounts of other beneficial owners. The Notes are also subject to 
redemption as provided under " Tender at Option of Beneficial Owners" above.

                                       S-16
<PAGE>

     The redemption type to be chosen by the Operating Partnership and the 
Remarketing Underwriter on the Duration/Mode Determination Date may be one of 
the following as defined herein: (i) Par Redemption; (ii) Premium Redemption 
or (iii) Make-Whole Redemption.  "Par Redemption" means redemption at a 
redemption price equal to 100% of the principal amount thereof, plus accrued 
interest thereon, if any, to the redemption date.  "Premium Redemption" means 
redemption at a redemption price or prices greater than 100% of the principal 
amount thereof, plus accrued interest thereon, if any, to the redemption 
date, as determined on the Duration/Mode Determination Date.  "Make-Whole 
Redemption" means redemption at a redemption price equal to the sum of (A) 
the principal amount of the Notes being redeemed plus accrued interest 
thereof, if any, to the redemption date and (B) the Make-Whole Amount (as 
defined below) if any, with respect to such Notes.

     "MAKE-WHOLE AMOUNT" means, in connection with any optional redemption or 
accelerated payment of any Note, the excess, if any, of (i) the aggregate 
present value as of the date of such redemption or accelerated payment of 
each dollar of principal being redeemed or paid and the amount of interest 
(exclusive of interest accrued to the date of redemption or accelerated 
payment) that would have been payable in respect of such dollar if such 
redemption or accelerated payment had not been made, determined by 
discounting, on a semiannual basis, such principal and interest at the 
Reinvestment Rate (determined on the third Business Day preceding the date 
such notice of redemption is given or declaration of acceleration is made) 
from the respective dates on which such principal and interest would have 
been payable if such redemption or accelerated payment had not been made, 
over (ii) the aggregate principal amount of the Notes being redeemed or paid.

     "REINVESTMENT RATE" means .25% plus the yield on treasury securities at 
constant maturity under the heading "Week Ending" published in the 
Statistical Release (as defined below) under the caption "Treasury Constant 
Maturities" for the maturity (rounded to the nearest month) corresponding to 
the remaining life to maturity, as of the payment date of the principal being 
redeemed or paid.  If no maturity exactly corresponds to such maturity, 
yields for the two published maturities most closely corresponding to such 
maturity shall be calculated pursuant to the immediately preceding sentence 
and the Reinvestment Rate shall be interpolated or extrapolated from such 
yields on a straight-line basis, rounding in each of such relevant periods to 
the nearest month.  For purposes of calculating the Reinvestment Rate, the 
most recent Statistical Release published prior to the date of determination 
of the Make-Whole Amount shall be used.

     "STATISTICAL RELEASE" means the statistical release designated "H. 
15(519)" or any successor publication which is published weekly by the 
Federal Reserve System and which establishes yields on actively traded United 
States government securities adjusted to constant maturities or, if such 
statistical release is not published at the time of any determination under 
the Indenture, then such other reasonably comparable index which shall be 
designated by the Rate Agent, after consultation with the Operating 
Partnership.

BOOK-ENTRY SYSTEM

     The following are summaries of certain rules and operating procedures of 
DTC that affect the payment of principal and interest and transfers of 
interests in the Global Notes.  Upon issuance, the Notes will be issued only 
in the form of Global Notes which will be deposited with, or on behalf of, 
DTC and registered in the name of Cede & Co., as nominee of DTC.  Unless and 
until it is exchanged in whole or in part for Notes in definitive form under 
the limited circumstances described below, the Global Notes may not be 
transferred except as a whole (i) by DTC to a nominee of DTC, (ii) by a 
nominee of DTC to DTC or another nominee of DTC, or (iii) by DTC or any such 
nominee to a successor of DTC or a nominee of such successor.

     Ownership of beneficial interests in the Global Notes will be limited to 
persons that have accounts with DTC for the Global Notes ("Participants") or 
persons that may hold interests through Participants. Upon the issuance of 
the Global Notes, DTC will credit, on its book-entry registration and 
transfer system, the Participants' accounts with the respective principal 
amounts of the Notes represented by the Global Notes beneficially owned by 
such Participants. Ownership of beneficial interests in the Global Notes will 
be shown on, and the transfer of such ownership interests will be effected 
only through, records maintained by DTC (with respect to interests of 
Participants) and on the records of Participants (with respect to interests 
of persons holding through Participants).  The laws of some states may 
require that certain purchasers of securities take physical delivery of such 
securities in definitive form.  Such limits and such laws may impair the 
ability to own, transfer, or pledge beneficial interests in the Global Notes.

     So long as DTC or its nominee is the registered owner of the Global 
Notes, DTC or such nominee, as the case may be, will be considered the sole 
owner or holder of the Notes represented by the Global Notes for all purposes 
under the Indenture.  Except as set forth below, owners of beneficial 
interests in the Global Notes will not be entitled to have the interests 
represented by the Global Notes registered in their names, will not receive 
or be entitled to receive physical delivery 

                                       S-17
<PAGE>

of the Notes in definitive form and will not be considered the owners or 
holders thereof under the Indenture. Accordingly, each person owning a 
beneficial interest in the Global Notes must rely on the procedures of DTC 
and, if such person is not a Participant, on the procedures of the 
Participant through which such person owns its interest, to exercise any 
rights of a holder under the Indenture.  The Operating Partnership 
understands that under existing industry practices, if the Operating 
Partnership requests any action of holders or if an owner of a beneficial 
interest in the Global Notes desires to give or take any action that a holder 
is entitled to give or take under the Indenture, DTC would authorize the 
Participants holding the relevant beneficial interests to give or take such 
action, and such Participants would authorize beneficial owners owning 
through such Participants to give or take such action or would otherwise act 
upon the instructions of beneficial owners holding through them.

     Principal and interest payments on interests represented by the Global 
Notes will be made to DTC or its nominee, as the case may be, as the 
registered owner of the Global Notes.  None of the Operating Partnership, the 
Trustee or any other agent of the Operating Partnership or agent of the 
Trustee will have any responsibility or liability for any aspect of the 
records relating to or payments made on account of beneficial ownership 
interests in the Global Notes or for maintaining, supervising or reviewing 
any records relating to such beneficial ownership interests.

     The Operating Partnership expects that DTC, upon receipt of any payment 
of principal or interest in respect of the Global Notes, will immediately 
credit Participants' accounts with payments in amounts proportionate to their 
respective beneficial interests in the Global Notes as shown on the records 
of DTC.  The Operating Partnership also expects that payments by Participants 
to owners of beneficial interests in the Global Notes held through such 
participants will be governed by standing customer instructions and customary 
practices, as is now the case with the securities held for the accounts of 
customers in bearer form or registered in "street name," and will be the 
responsibility of such Participants.

     If DTC, is at any time unwilling or unable to continue as depository for 
the Notes and the Operating Partnership fails to appoint a successor 
depository registered as a clearing agency under the Securities Exchange Act 
of 1934, as amended, within 90 days, the Operating Partnership will issue the 
Notes in definitive form in exchange for the Global Notes.  Any Notes issued 
in definitive form in exchange for the Global Notes will be registered in 
such name or names, and will be issued in denominations of $1,000 and such 
integral multiples thereof, as DTC shall instruct the Trustee.  It is 
expected that such instructions will be based upon directions received by DTC 
from Participants with respect to ownership of beneficial interests in the 
Global Notes.

     DTC has advised the Operating Partnership of the following information 
regarding DTC: DTC is a limited-purpose trust company organized under the 
Banking Law of the State of New York, a "banking organization" within the 
meaning of the Banking Law of the State of New York, a member of the Federal 
Reserve System, a "clearing corporation" within the meaning of the New York 
Uniform Commercial Code, and a "clearing agency" registered pursuant to the 
provisions of Section 17A of the Exchange Act.  DTC was created to hold 
securities of its Participants and to facilitate the clearance and settlement 
of transactions among its Participants in such securities through electronic 
book-entry changes in accounts of the Participants, thereby eliminating the 
need for physical movement of securities certificates. DTC's Participants 
include securities brokers and dealers, banks, trust companies, clearing 
corporations, and certain other organizations, some of which (and/or their 
representatives) own DTC.  Access to DTC book-entry system is also available 
to others, such as banks, brokers, dealers, and trust companies that clear 
through or maintain a custodial relationship with a Participant, either. 
directly or indirectly.

              CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

     The following summary of certain United States Federal income tax 
consequences of the purchase, ownership and disposition of the Notes is based 
upon the Internal Revenue Code of 1986, as amended (the "Code"), regulations 
promulgated thereunder ("Treasury Regulations"), and rulings and decisions 
now in effect, all of which are subject to change (prospectively or 
retroactively). The following discussion deals only with Notes held as 
capital assets and does not purport to deal with persons in special tax 
situations, such as financial institutions, banks, insurance companies, 
regulated investment companies, dealers in securities or currencies, persons 
holding Notes as a hedge against currency risks or as a position in a 
"straddle" for tax purposes, or persons whose functional currency is not the 
United States dollar.  It also does not deal with holders other than original 
purchasers buying the Notes at the original offering price (except where 
otherwise specifically noted).  It does not discuss any state, local or 
foreign tax consequences and does not discuss all aspects of Federal income 
taxation that might be relevant to a specific holder in light of its 
particular investment or tax circumstances.  

     PERSONS CONSIDERING THE PURCHASE OF THE NOTES SHOULD CONSULT THEIR OWN 
TAX ADVISORS WITH RESPECT TO THE TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP 
AND DISPOSITION OF THE NOTES, INCLUDING THE TAX CONSEQUENCES UNDER STATE, 
LOCAL, FOREIGN AND OTHER TAX LAWS AND THE POSSIBLE EFFECTS OF CHANGES IN 
UNITED STATES FEDERAL OR OTHER TAX LAWS.

     As used herein, the term "U.S. Holder" means a beneficial owner of a 
Note that is for United States Federal income tax purposes (i) a citizen or 
resident of the United States, (ii) a corporation, partnership or other 
entity created or organized in or under the laws of the United States or of 
any state thereof, (iii) an estate the income of which is subject to United 
States Federal income taxation regardless of its source, or (iv) a trust if a 
court within the United States is able to exercise primary supervision over 
the administration of the trust and one or more United States persons have 
the authority to control all substantial decisions of the trust.  As used 
herein, the term "Non-U.S. Holder" means a beneficial owner of a Note that is 
not a U.S. Holder.

U.S. HOLDERS

     PAYMENTS OF INTEREST.  The Notes should constitute "variable rate debt 
instruments" ("VRDI") and the interest payments received should be considered 
"qualified stated interest" under section 1.1275-5 of the Treasury 
Regulations. The interest received will thus be taxable to a U.S. Holder as 
ordinary interest income at the time such payments are accrued or received in 
accordance with the U.S. Holder's regular method of tax accounting.

     DISPOSITION OF A NOTE.  Based on the foregoing treatment, upon the sale, 
exchange or retirement of a Note, a U.S. Holder generally will recognize 
taxable gain or loss in an amount equal to the difference, if any, between 
the amount realized upon the sale, exchange or retirement (other than amounts 
representing accrued and unpaid interest which will be taxable as interest 
income) and such U.S. Holder's adjusted tax basis in the Note.  A U.S. 
Holder's adjusted tax basis in a Note is generally equal to such U.S. 
Holder's initial investment in such Note.  Any such gain or loss generally 
will be capital gain or loss, and generally will be a long-term capital gain 
or loss if the Notes have been held for more than one year prior to the date 
of disposition.  Tax rates on capital gains received by individual U.S. 
Holders vary depending on each U.S. Holder's income and holding period for 
the Notes.  U.S. Holders who are individuals should contact their own tax 
advisors for more information or for the capital gains rate applicable to a 
specific Note.  The deduction of capital losses is subject to certain 
limitations.

     OTHER POSSIBLE TREATMENT OF THE NOTES.  While the Operating Partnership 
intends to treat the Notes as VRDIs issued without original issue discount 
("OID"), it is possible that the Internal Revenue Service ("IRS") will take 
the position that the Notes are either (i) VRDIs issued with OID, or (ii) 
contingent payment debt instruments.  In the event the IRS were successful in 
either assertion, holders of Notes could experience U.S. Federal income tax 
consequences significantly different from those discussed herein.  
Prospective purchasers of Notes are urged to consult their tax advisors as to 
the potential application of, and the consequences of applying, the 
regulations governing VRDIs issued with OID and contingent payment 
obligations.

NON-U.S. HOLDERS

     A non-U.S. Holder will not be subject to Federal income taxes on payment 
of principal, premium (if any) or interest of a Note, unless such non-U.S. 
Holder is a direct or indirect 10% or greater partner of the Operating 
Partnership, a controlled foreign corporation related to the Operating 
Partnership or a bank receiving interest described in section 881(c)(3)(A) of 
the 

                                       S-19
<PAGE>

Code, and provided that the interest is not effectively connected with 
the conduct of a trade or business in the United States by the non-U.S. 
Holder.  To qualify for the exemption from taxation, the last United States 
payor in the chain of payment prior to payment to a non-U.S. Holder (the 
"Withholding Agent") must have received in the year in which a payment of 
interest or principal occurs, or in either of the two preceding calendar 
years, a statement that (i) is signed by the beneficial owner of the Note 
under penalties of perjury, (ii) certifies that such owner is not a U.S. 
Holder and (iii) provides the name and address of the beneficial owner.  The 
statement may be made on an IRS Form W-8 or a substantially similar form, and 
the beneficial owner must inform the Withholding Agent of any change in the 
information on the statement within 30 days of such change.  If a Note is 
held through a securities clearing organization or certain other financial 
institutions, the organization or institution may provide a signed statement 
to the Withholding Agent.  However, in such case, the signed statement must 
be accompanied by a copy of the IRS Form W-8 or the substitute form provided 
by the beneficial owner to the organization or institution.  The Treasury 
Department is considering implementation of further certification 
requirements aimed at determining whether the issuer of a debt obligation is 
related to holders thereof.

     Generally, a non-U.S. Holder will not be subject to Federal income taxes 
on any amount which constitutes gain upon retirement or disposition of a 
Note, provided the gain is not effectively connected with the conduct of a 
trade or business in the United States by the non-U.S. Holder.  Certain other 
exceptions may be applicable, and a non-U.S. Holder should consult its tax 
advisor in this regard.

     If a non-U.S. Holder is engaged in a trade or business in the United 
States and interest or gain on the Note is effectively connected with the 
conduct of such trade or business, such holder, although exempt from U.S. 
Federal withholding tax as discussed above (or by reason of the delivery of a 
properly completed Form 4224), is subject to U.S. Federal income tax on such 
interest and on any gain realized on the sale, exchange or other disposition 
of a Note in the same manner as if it were a U.S. Holder.  In addition, if 
such non-U.S. Holder is a foreign corporation, it may be subject to a branch 
profits tax equal to 30% of its effectively connected earnings and profits 
for that taxable year, unless it qualifies for a lower rate under an 
applicable income tax treaty.

     The Notes will not be includible in the estate of a non-U.S. Holder 
unless the individual is a direct or indirect 10% or greater partner of the 
Operating Partnership or, at the time of such individual's death, payments in 
respect of the Notes would have been effectively connected with the conduct 
by such individual of a trade or business in the United States.

BACKUP WITHHOLDING AND INFORMATION REPORTING

     Backup withholding of United States Federal income tax at a rate of 31% 
may apply to payments made in respect of the Notes to registered owners who 
are not "exempt recipients" and who fail to provide certain identifying 
information (such as the registered owner's taxpayer identification number) 
in the required manner.  Generally, individuals are not exempt recipients, 
whereas corporations and certain other entities generally are exempt 
recipients.  Payments made in respect of the Notes to a U.S. Holder must be 
reported to the IRS, unless the U.S. Holder is an exempt recipient or 
establishes an exemption.  Compliance with the identification procedures 
described in the preceding section would establish an exemption from backup 
withholding for those non-U.S. Holders who are not exempt recipients.

     In addition, upon the sale of a Note to (or through) a broker, the 
broker must withhold 31% of the entire purchase price, unless either (i) the 
broker determines that the seller is a corporation or other exempt recipient 
or (ii) the seller provides, in the required manner, certain identifying 
information and, in the case of a non-U.S. Holder, certifies that such seller 
is a non-U.S. Holder (and certain other conditions are met).  Such a sale 
must also be reported by the broker to the IRS, unless either (i) the broker 
determines that the seller is an exempt recipient or (ii) the seller 
certifies its non-U.S. status (and certain other conditions are met).  
Certification of the registered owner's non-U.S. status would normally be 
made on an IRS Form W-8 under penalties of perjury, although in certain cases 
it may be possible to submit other documentary evidence.

     Any amounts withheld under the backup withholding rules from a payment 
to a beneficial owner would be allowed as a refund or a credit against such 
beneficial owner's Federal income tax provided the required information is 
furnished to the IRS.

NEW WITHHOLDING REGULATIONS

     On October 6, 1997, the Treasury Department issued new regulations (the
"New Regulations") which make certain modifications to the withholding, backup
withholding and information reporting rules described above.  The New
Regulations attempt to unify certification requirements and modify reliance
standards.  The IRS has announced that the New Regulations will generally be
effective for payments made after December 31, 1999, subject to certain
transition rules.  Valid 

                                       S-20
<PAGE>

withholding certificates that are held on December 31, 1999 will remain valid 
until the earlier of December 31, 2000 or the expiration of the certificate 
under rules currently in effect (unless otherwise invalidated due to changes 
in circumstances of the person whose name is on such certificate).  
Prospective investors are urged to consult their own tax advisors regarding 
the New Regulations.

     The Underwriters have advised the Operating Partnership that the 
Underwriters propose to offer the Notes from time to time for sale in 
negotiated transactions or otherwise, at prices determined at the time of 
sale.  The Underwriters may effect such transactions by selling Notes to or 
through dealers and such dealers may receive compensation in the form of 
underwriting discounts, concessions or commissions from the Underwriters and 
any purchasers of Notes for whom they may act as agent.  The Underwriters and 
any dealers that participate with the Underwriters in the distribution of the 
Notes may be deemed to be underwriters, and any discounts or commissions 
received by them and any profit on the resale of Notes by them may be deemed 
to be underwriting compensation.

     The Notes are a new issue of securities with no established trading 
market. The Operating Partnership does not intend to apply for listing of the 
Notes on a national securities exchange.  The Operating Partnership has been 
advised by the Underwriters that they intend to make a market in the Notes as 
permitted by applicable laws and regulations, but are not obligated to do so 
and may discontinue market making at any time without notice.   No assurance 
can be given as to the liquidity of the trading market for the Notes.

     Until the distribution of the Notes is completed, rules of the 
Commission may limit the ability of the Underwriters to bid for and purchase 
the Notes.  As an exception to these rules, the Underwriters are permitted to 
engage in certain transactions that stabilize the price of the Notes.  Such 
transactions consist of bids or purchases for the purpose of pegging, fixing 
or maintaining the price of the Notes.

     If the Underwriters create a short position in the Notes in connection 
with the offering, I.E., if they sell more of the Notes than are set forth on 
the cover page of this Prospectus Supplement, the Underwriters may reduce 
that short position by purchasing Notes in the open market.

     In general, purchasers of a security for the purpose of stabilization or 
to reduce a short position could cause the price of the security to be higher 
than it might be in the absence of such purchases.

     Neither the Operating Partnership nor the Underwriters make any 
representation or prediction as to the direction or magnitude of any effect 
that the transactions described above may have on the prices of the Notes.  
In addition, neither the Operating Partnership nor the Underwriters make any 
representation that the Underwriters will engage in such transactions or that 
such transactions, once commenced, will not be discontinued without notice. 

     The Operating Partnership has agreed to indemnify the Underwriters 
against certain civil liabilities, including liabilities under the Securities 
Act of 1933, as amended (the "Securities Act"), or to contribute to payments 
the Underwriters may be required to make in respect thereof. 

     The Underwriters from time to time provides investment banking and 
financial advisory services to the Company and other entities owned or 
controlled by Mr. Zell, and affiliates of the Underwriters from time to time 
provide financing to such entities.

     The Operating Partnership has purchased, and may purchase in the future,
multifamily properties from affiliates of Merrill Lynch, Pierce, Fenner & Smith
Incorporated.

OPERATING PARTNERSHIP AND THOSE ENTITIES OWNED OR CONTROLLED BY IT ON A 
CONSOLIDATED BASIS, UNLESS THE CONTEXT INDICATES OTHERWISE.  AS USED HEREIN, 
THE TERM "COMPANY" INCLUDES EQUITY RESIDENTIAL PROPERTIES TRUST ("EQR") AND

                             THE OPERATING PARTNERSHIP

GENERAL

     The Debt Securities offered hereby are being issued by the Operating 
Partnership which is managed by EQR, its general partner.  The Company, one 
of the largest publicly traded real estate investment trusts ("REITs") (based 
on the aggregate market value of its outstanding equity capitalization), is a 
self-administered and self-managed equity REIT.  EQR was organized as a 
Maryland real estate investment trust in March 1993 and commenced operations 
as a publicly traded company on August 18, 1993 upon completion of its 
initial public offering (the "IPO").  EQR was formed to continue the 
multifamily property business objectives and acquisition strategies of 
certain affiliated entities controlled by Mr. Samuel Zell, Chairman of the 
Board of Trustees of EQR.  These entities had been engaged in the 
acquisition, ownership and operation of multifamily properties since 1969.  
In May 1997, EQR completed the acquisition of the multifamily property 
business of Wellsford through the tax-free merger of the Company and 
Wellsford.  In December 1997, EQR completed the acquisition of the 
multifamily property business of EWR through the tax-free merger of EWR and 
the Company.  The Company's senior executives average over 24 years of 
experience in the multifamily property business.

     All of the Company's interests in its multifamily properties (the 
"Properties") are held or controlled directly or indirectly by, and 
substantially all of its operations relating to the Properties are conducted 
through, the Operating Partnership.

     The Operating Partnership currently has eight classes of limited 
partnership interests outstanding:  (i) partnership interests ("OP Units"), 
which may be exchanged by the holders thereof for either common shares of 
beneficial interest of the Company, $.01 par value per share ("Common 
Shares"), on a one-for-one basis or, at the Company's option, cash; (ii) 9 
3/8% Series A Cumulative Redeemable Preference Units ("9 3/8% Series A 
Preference Units"); (iii) 9 1/8% Series B Cumulative Redeemable Preference 
Units ("9 1/8% Series B Preference Units"); (iv) 9 1/8% Series C Cumulative 
Redeemable Preference Units ("9 1/8% Series C Preference Units"); (v) 8.60% 
Series D Cumulative Redeemable Preference Units ("8.60% Series D Preference 
Units"); (vi) Series E Cumulative Convertible Preference Units ("Series E 
Preference Units"),  (vii) 9.65% Series F Cumulative Redeemable Preference 
Units ("9.65% Series F Preference Units") and (viii) 7 1/4% Series G 
Convertible Cumulative Preference Units ("7 1/4% Series G Preference Units"). 
 The 9 3/8% Series A Preference Units, the 9 1/8% Series B Preference Units, 
the 9 1/8% Series C Preference Units, the 8.60% Series D Preference Units, 
the Series E Preference Units, the 9.65% Series F Preference Units and the 7 
1/4% Series G Preference Units (collectively, the "Outstanding Preference 
Units") are owned by the Company and mirror the payments of distributions, 
including accrued and unpaid distributions upon redemption, and of the 
liquidating preference amount of the Company's 9 3/8% Series A Cumulative 
Redeemable Preferred Shares of Beneficial Interest, $.01 par value per share 
(the "Series A Preferred Shares"), the Company's 9 1/8% Series B Cumulative 
Redeemable Preferred Shares of Beneficial Interest, $.01 par value per share 
(the "Series B Preferred Shares"), the Company's 9 1/8% Series C Cumulative 
Redeemable Preferred Shares of Beneficial Interest, $.01 par value per share

(the "Series E Preferred Shares"), the Company's 9.65% Series F Preferred

"Series G Preferred Shares" and, collectively with the Series A Preferred 
Shares, the Series B Preferred Shares, the Series C Preferred Shares, the 
Series D Preferred Shares, the Series E Preferred Shares and the Series F 
Preferred Shares, the "Outstanding Preferred Shares"), respectively.  The 
Company controls the Operating Partnership as the sole general partner and, 
as of March 31, 1998, owned approximately 91% of all of the Operating 
Partnership's outstanding partnership interests, excluding the Outstanding 
Preference Units.  It is the Company's policy that Equity Residential 
Properties Trust shall not incur indebtedness other than short-term trade, 
employee compensation, dividends payable or similar indebtedness that will be 
paid in the ordinary course of business, and that indebtedness shall instead 
be incurred by the Operating Partnership to the extent necessary to fund the 
business activities conducted by the Operating Partnership and its 
subsidiaries.

     The Operating Partnership's and the Company's corporate headquarters and 
executive offices are located at Two North Riverside Plaza, Suite 400, 
Chicago, Illinois 60606, and its telephone number is (312) 474-1300.  In 
addition, the Operating Partnership has 30 management offices in the 
following cities: Chicago, Illinois; Denver, Colorado; Seattle, Federal Way 
and Redmond, Washington; Bethesda, Maryland; Atlanta, Georgia; Las Vegas, 
Nevada; Scottsdale and Tucson, Arizona; Portland, Oregon; Dallas, Houston and 
San Antonio, Texas; Irvine, Pleasant Hill and Stockton, California;

THE OPERATING SUBSIDIARIES

     Essentially all operations of the Company are conducted directly or 
indirectly by the Operating Partnership and those entities owned or 
controlled by the Operating Partnership (collectively, the "Subsidiaries"), 
so that, among other things, the Company is able to comply with certain 
technical and complex requirements under the federal tax law relating to the 
assets and income that a REIT may hold or earn.  In this regard, the Company 
has established:  (i) the Operating Partnership which benefited those 
entities that contributed certain of the 69 Properties acquired by the 
Operating Partnership in connection with the IPO in exchange for OP Units by 
allowing them to partially defer certain tax consequences and which will 
allow the Operating Partnership to acquire additional multifamily properties 
in transactions that may defer some or all of the sellers' tax consequences, 
(ii) Equity Residential Properties Management Corp., Equity Residential 
Properties Management Corp. II, Equity Residential Properties Management 
Corp. III, Wellsford Holly Management, Inc. and Evans Withycombe Management, 
Inc. (collectively, the "Management Corps") and Equity Residential Properties 
Management Limited Partnership and Equity Residential Properties Management 
Limited Partnership II (collectively, the "Management Partnerships") provide 
management services because the income from such operations might jeopardize 
the Company's REIT status if such services were provided directly by the 
Company or the Operating Partnership to third parties, and (iii) a series of 
limited partnerships and limited liability companies which own the beneficial 
interest of certain of the Properties which are encumbered by mortgage 
financing.  The Operating Partnership and its Subsidiaries perform 
substantially all ownership and management functions with respect to the 
Properties.

                                  USE OF PROCEEDS

     Unless otherwise indicated in the accompanying Prospectus Supplement, 
the Operating Partnership intends to use the proceeds from the sale of the 
Debt Securities for general purposes including, without limitation, the 
acquisition of multifamily properties and the repayment of debt.

                    RATIOS OF EARNINGS TO COMBINED FIXED CHARGES
                         AND PREFERENCE UNIT DISTRIBUTIONS

     The following table sets forth the Operating Partnership's ratios of 
earnings to combined fixed charges and preference unit distributions for the 
periods shown.

     Ratio of earnings to combined fixed charges and preference unit 
distributions represents the ratio of income before gain on disposition of 
properties, extraordinary items and allocation to minority interests plus 
fixed charges (principally interest expense incurred) to fixed charges and 
preference unit distributions.

     The reorganization and recapitalization of the Company and the Operating 
Partnership effected in connection with the IPO in 1993 permitted the Company 
and the Operating Partnership to significantly deleverage the Properties 
resulting in an improved ratio of earnings to combined fixed charges and 
preference unit distributions for periods subsequent to the IPO.

                           DESCRIPTION OF DEBT SECURITIES


     The following description sets forth certain general terms and 
provisions of the Debt Securities to which any Prospectus Supplement may 
relate.  The particular terms of the Debt Securities being offered and the 
extent to which such general provisions may apply will be described in a 
Prospectus Supplement relating to such Debt Securities.

     The Debt Securities will be issued under an Indenture dated as of 
October 1, 1994, as amended or supplemented from time to time (the 
"Indenture"), between the Operating Partnership and The First National Bank 
of Chicago, as trustee (the "Trustee").  The Indenture has been filed as an 
exhibit to the Registration Statement of which this Prospectus is a part and 
is available for inspection at the corporate trust office of the Trustee at 
14 Wall Street, Eighth Floor, New York, New York or as described above under 
"Available Information."  The Indenture is subject to, and governed by, the 
Trust Indenture Act of 1939, as amended (the "TIA").  The statements made 
hereunder relating to the Indenture and the Debt Securities to be issued 
thereunder are summaries of certain provisions thereof and do not purport to 
be complete and are subject to, and are qualified in their entirety by 
reference to, all provisions of the Indenture and such Debt Securities.  All 
section references appearing herein are to sections of the Indenture, and 
capitalized terms used but not defined herein shall have the respective 
meanings set forth in the Indenture.

GENERAL

     The Debt Securities will be direct, unsecured obligations of the 
Operating Partnership and will rank equally with all other unsecured and 
unsubordinated indebtedness of the Operating Partnership.  Unless otherwise 
specified in the applicable Prospectus Supplement, the Company has no 
obligation for payment of principal of or interest on the Debt Securities.  
The Debt Securities may be issued in one or more series, in each case as 
established from time to time in or pursuant to authority granted by a 
resolution of the Board of Trustees of the Company, as general partner of the 
Operating Partnership, or as established in the Indenture or in one or more 
indentures supplemental to the Indenture.  All Debt Securities of one series 
need not be issued at the same time and, unless otherwise provided, a series 
may be reopened, without the consent of the Holders of the Debt Securities of 
such series, for issuances of additional Debt Securities of such series 
(Section 301).

     The Indenture provides that there may be more than one Trustee 
thereunder, each with respect to one or more series of Debt Securities.  Any 
Trustee under the Indenture may resign or be removed with respect to one or 
more series of Debt Securities, and a successor Trustee may be appointed to 
act with respect to such series (Section 608).  In the event that two or more 
persons are acting as Trustee with respect to different series of Debt 
Securities, each such Trustee shall be a Trustee of a trust under the 
applicable Indenture separate and apart from the trust administered by any 
other Trustee (Section 609), and, except as otherwise indicated herein, any 
action described herein to be taken by the Trustee may be taken by each such 
Trustee with respect to, and only with respect to, the one or more series of 
Debt Securities for which it is Trustee under the Indenture.

     Reference is made to the Prospectus Supplement relating to the series of 
Debt Securities being offered for the specific terms thereof, including 
without limitation:

     (1)    the title of such Debt Securities;

     (2)    the aggregate principal amount of such Debt Securities and any
            limit on such aggregate principal amount;

     (3)    the percentage of the principal amount at which such Debt
            Securities will be issued and, if other than the principal amount
            thereof, the portion of the principal amount thereof payable upon
            declaration of acceleration of the maturity thereof;

     (4)    the date or dates, or the method for determining such date or
            dates, on which the principal of such Debt Securities will be
            payable;

     (5)    the rate or rates (which may be fixed or variable), or the method
            by which such rate or rates shall be determined, at which such Debt
            Securities will bear interest, if any;

     (6)    the date or dates, or the method for determining such date or
            dates, from which any such interest will accrue, the Interest
            Payment Dates on which any such interest will be payable, the
            Regular Record Dates for such Interest Payment Dates, or the method
            by which such dates shall be determined, the Person to whom such
            interest shall be payable, and the basis upon which interest shall
            be calculated if other than that of a 360-day year of twelve 30-day
            months;



                                        7
<PAGE>

     (7)    the place or places where (i) the principal of (and premium and
            Make-Whole Amounts (as defined below), if any) and interest, if
            any, on such Debt Securities will be payable, (ii) such Debt
            Securities may be surrendered for conversion or registration of
            transfer or exchange and (iii) notices or demands to or upon the
            Operating Partnership in respect of such Debt Securities and the
            Indenture may be served;

     (8)    the period or periods within which, the price or prices at which
            and the terms and conditions upon which such Debt Securities may be
            redeemed, in whole or in part, at the option of the Operating
            Partnership, if the Operating Partnership is to have such an
            option;

     (9)    the obligation, if any, of the Operating Partnership to redeem,
            repay or purchase such Debt Securities at the option of a Holder
            thereof, and the period or periods within which, the price or
            prices as to which and the terms and conditions upon which such
            Debt Securities will be redeemed, repaid or purchased, in whole or
            in part, pursuant to such obligation;

     (10)   if other than United States dollars, the currency or currencies in
            which such Debt Securities are denominated and payable, which may
            be a foreign currency or units of two or more foreign currencies or
            a composite currency or currencies, and the terms and conditions
            relating thereto;

     (11)   whether the amount of payments of principal (and premium, if any)
            or interest, if any, on such Debt Securities may be determined with
            reference to an index, formula or other method (which index,
            formula or other method may, but need not be, based on a currency,
            currencies, currency unit or units or composite currency or
            currencies) and the manner in which such amounts shall be
            determined;

     (12)   any additions to, modifications of or deletions from the terms of
            such Debt Securities with respect to the Events of Default or
            covenants, set forth in the Indenture;

     (13)   whether such Debt Securities will be issued in certificated or
            book-entry form;

     (14)   whether such Debt Securities will be in registered or bearer form
            and, if in registered form, the denominations thereof if other than
            $1,000 and any integral multiple thereof and, if in bearer form,
            the denominations thereof and the terms and conditions relating
            thereto;

     (15)   the applicability, if any, of the defeasance and covenant
            defeasance provisions of Article Fourteen of the Indenture;

     (16)   whether and under what circumstances the Operating Partnership will
            pay Additional Amounts as contemplated in the Indenture in respect
            of any tax, assessment or governmental charge and, if so, whether
            the Operating Partnership will have the option to redeem such Debt
            Securities in lieu of making such payment; and

     (17)   any other terms of such Debt Securities not inconsistent with the
            provisions of the Indenture (Section 301).

     The Debt Securities may provide for less than the entire principal amount
thereof to be payable upon declaration of acceleration of the maturity thereof
("Original Issue Discount Securities").  Special United States federal income
tax, accounting and other considerations applicable to Original Issue Discount
Securities will be described in the applicable Prospectus Supplement.

     Except as set forth below under "Certain Covenants - Limitations on
Incurrence of Debt," the Indenture does not contain any other provisions that
would limit the ability of the Operating Partnership to incur indebtedness or
that would afford Holders of Debt Securities protection in the event of a highly
leveraged or similar transaction involving the Operating Partnership or in the
event of a change of control.  However, restrictions on ownership and transfers
of the Company's Common Shares and preferred shares of beneficial interest are
designed to preserve its status as a REIT and, therefore, may act to prevent or
hinder a change of control.  Reference is made to the applicable Prospectus
Supplement for information with respect to any deletions from, modifications of
or additions to the Events of Default or covenants of the Operating Partnership
that are described below, including any addition of a covenant or other
provision providing event risk or similar protection.

DENOMINATIONS, INTEREST, REGISTRATION AND TRANSFER

     Unless otherwise described in the applicable Prospectus Supplement, the 
Registered Securities of any series will be issuable in denominations of 
$1,000 and integral multiples thereof (Section 302).

     Unless otherwise specified in the applicable Prospectus Supplement, the 
principal of (and premium, if any) and interest on any series of Debt 
Securities will be payable at the corporate trust office of the Trustee, 
initially located at 14 Wall Street, Eighth Floor, New York, New York; 
provided that, at the option of the Operating Partnership, payment of 
interest may be made by check mailed to the address of the Person entitled 
thereto as it appears in the Security Register or by wire transfer of funds 
to such Person at an account maintained within the United States (Sections 
301, 305, 306, 307 and 1002).

     Any interest not punctually paid or duly provided for on any Interest 
Payment Date with respect to a Debt Security ("Defaulted Interest") will 
forthwith cease to be payable to the Holder on the applicable Regular Record 
Date and may either be paid to the person in whose name such Debt Security is 
registered at the close of business on a special record date (the "Special 
Record Date") for the payment of such Defaulted Interest to be fixed by the 
Trustee, notice whereof shall be given to the Holder of such Debt Security 
not less than 10 days prior to such Special Record Date, or may be paid at 
any time in any other lawful manner, all as more completely described in the 
Indenture (Section 307).

     Subject to certain limitations imposed upon Debt Securities issued in 
book-entry form, the Debt Securities of any series will be exchangeable for 
other Debt Securities of the same series and of a like aggregate principal 
amount and tenor of different authorized denominations upon surrender of such 
Debt Securities at the corporate trust office of the Trustee referred to 
above. In addition, subject to certain limitations imposed upon Debt 
Securities issued in book-entry form, the Debt Securities of any series may 
be surrendered for conversion or registration of transfer or exchange thereof 
at the corporate trust office of the Trustee.  Every Debt Security 
surrendered for conversion, registration of transfer or exchange shall be 
duly endorsed or accompanied by a written instrument of transfer.  No service 
charge will be made for any registration of transfer or exchange of any Debt 
Securities, but the Operating Partnership may require payment of a sum 
sufficient to cover any tax or other governmental charge payable in 
connection therewith (Section 305).  If the applicable Prospectus Supplement 
refers to any transfer agent (in addition to the Trustee) initially 
designated by the Operating Partnership with respect to any series of Debt 
Securities, the Operating Partnership may at any time rescind the designation 
of any such transfer agent or approve a change in the location through which 
any such transfer agent acts, except that the Operating Partnership will be 
required to maintain a transfer agent in each Place of Payment for such 
series.  The Operating Partnership may at any time designate additional 
transfer agents with respect to any series of Debt Securities (Section 1002).

     Neither the Operating Partnership nor the Trustee shall be required to 
(i) issue, register the transfer of or exchange Debt Securities of any series 
during a period beginning at the opening of business 15 days before any 
selection of Debt Securities of that series to be redeemed and ending at the 
close of business on the day of mailing of the relevant notice of redemption; 
(ii) register the transfer of or exchange any Debt Security, or portion 
thereof, called for redemption, except the unredeemed portion of any Debt 
Security being redeemed in part; or (iii) issue, register the transfer of or 
exchange any Debt Security which has been surrendered for repayment at the 
option of the Holder, except the portion, if any, of such Debt Security not 
to be so repaid (Section 305).

MERGER, CONSOLIDATION OR SALE

     The Operating Partnership may consolidate with, or sell, lease or convey 
all or substantially all of its assets to, or merge with or into any other 
entity, provided that (i) the Operating Partnership shall be the continuing 
entity, or the successor entity shall be an entity organized and existing 
under the laws of the United States or a state thereof and such successor 
entity shall expressly assume payment of the principal of and premium (if 
any) and any interest (including all Additional Amounts, if any, payable 
pursuant to Section 1012) on all of the Debt Securities and the due and 
punctual performance and observance of all of the covenants and conditions 
contained in the Indenture, (ii) immediately after giving effect to such 
transaction and treating any indebtedness which becomes an obligation of the 
Operating Partnership or any Subsidiary as a result thereof as having been 
incurred by the Operating Partnership, or such Subsidiary at the time of such 
transaction, no Event of Default under the Indenture, and no event which 
after notice or the lapse of time, or both, would become such an Event of 
Default, shall have occurred and be continuing; and (iii) an officer's 
certificate of the Company as general partner of the Operating Partnership 
and legal opinion covering such conditions shall be delivered to the Trustee 
(Sections 801 and 803).

CERTAIN COVENANTS

     LIMITATIONS ON INCURRENCE OF DEBT.  The Operating Partnership will not, 
and will not permit any Subsidiary to incur any Debt (as defined below), 
other than intercompany Debt (representing Debt to which the only parties are 
the Company, the Operating Partnership and any of its Subsidiaries, (but only 
so long as such Debt is held solely by any of the Company, the Operating 
Partnership and any Subsidiary) that is subordinate in right of payment of 
the Debt Securities, if, immediately after giving effect to the incurrence of 
such additional Debt, the aggregate principal amount of all outstanding Debt 
of the Operating Partnership and its Subsidiaries on a consolidated basis 
determined in accordance with generally accepted accounting principles is 
greater than 60% of the sum of (i) the Operating Partnership's Total Assets 
(as defined below) as of the end of the calendar quarter covered in the 
Operating Partnership's Annual Report on Form 10-K or Quarterly Report on 
Form 10-Q, as the case may be, most recently filed with the Commission (or, 
if such filing is not permitted under the Exchange Act, with the Trustee) 
prior to the incurrence of such additional Debt and (ii) the increase in 
Total Assets from the end of such quarter including, without limitation, any 
increase in Total Assets caused by the incurrence of such additional Debt 
(such increase together with the Company's Total Assets shall be referred to 
as the "Adjusted Total Assets") (Section 1004).

     In addition to the foregoing limitation on the incurrence of Debt, the 
Operating Partnership will not and will not permit any Subsidiary to incur 
any Debt if the ratio of Consolidated Income Available for Debt Service to 
the Maximum Annual Service Charge for the four consecutive fiscal quarters 
most recently ended prior to the date on which such additional Debt is to be 
incurred shall have been less than 1.5 to 1, on a pro forma basis after 
giving effect to the incurrence of such Debt and to the application of the 
proceeds therefrom, and calculated on the assumption that (i) such Debt and 
any other Debt incurred by the Operating Partnership or its Subsidiaries 
since the first day of such four-quarter period and the application of the 
proceeds therefrom, including to refinance other Debt, had occurred at the 
beginning of such period, (ii) the repayment or retirement of any other Debt 
by the Operating Partnership or its Subsidiaries since the first day of such 
four-quarter period had been incurred, repaid or retired at the beginning of 
such period (except that, in making such computation, the amount of Debt 
under any revolving credit facility shall be computed based upon the average 
daily balance of such Debt during such period), (iii) the income earned on 
any increase in Adjusted Total Assets since the end of such four-quarter 
period had been earned, on an annualized basis, during such period; and (iv) 
in the case of any acquisition or disposition by the Operating Partnership or 
any Subsidiary of any asset or group of assets since the first day of such 
four-quarter period, including, without limitation, by merger, stock purchase 
or sale, or asset purchase or sale, such acquisition or disposition or any 
related repayment of Debt had occurred as of the first day of such period 
with the appropriate adjustments with respect to such acquisition or 
disposition being included in such pro forma calculation (Section 1004).

     In addition to the foregoing limitations on the incurrence of Debt, the 
Operating Partnership will not, and will not permit any Subsidiary to incur 
any Debt secured by any mortgage, lien, charge, pledge, encumbrance or 
security interest of any kind upon any of the property of the Operating 
Partnership or any Subsidiary ("Secured Debt"), whether owned at the date of 
the Indenture or thereafter acquired, if, immediately after giving effect to 
the incurrence of such additional Secured Debt, the aggregate principal 
amount of all outstanding Secured Debt of the Operating Partnership and its 
Subsidiaries on a consolidated basis is greater than 40% of the Adjusted 
Total Assets (Section 1004).

     Notwithstanding the limitation set forth in the preceding paragraph, the 
Indenture provides that the Operating Partnership and its Subsidiaries may 
incur Secured Debt, provided that such Secured Debt is incurred under the 
Acquisition Lines of Credit, and provided further that after the increase of 
such Secured Debt under the Acquisition Lines of Credit, the aggregate 
principal amount of all outstanding Secured Debt, including debt under the 
Acquisition Lines of Credit of the Operating Partnership or any Subsidiary 
does not exceed 45% of the Adjusted Total Assets; provided, however, that the 
aggregate principal amount of all outstanding Secured Debt of the Operating 
Partnership and its Subsidiaries on a consolidated basis may exceed 40% of 
the Adjusted Total Assets for not more than 270 days of any consecutive 360 
day period.

     For purposes of the foregoing provisions regarding the limitation on the 
incurrence of Debt, Debt shall be deemed to be "incurred" by the Operating 
Partnership and its Subsidiaries on a consolidated basis whenever the 
Operating Partnership and its Subsidiaries on a consolidated basis shall 
create, assume, guarantee or otherwise become liable in respect thereof.

     RESTRICTIONS ON DISTRIBUTIONS.  The Operating Partnership will not make 
any distribution, by reduction of capital or otherwise (other than 
distributions payable in securities evidencing interests in the Operating 
Partnership's capital for the purpose of acquiring interests in real property 
or otherwise) if, immediately after such distribution the aggregate of all 
such distributions made since March 31, 1993 shall exceed Funds from 
Operations of the Operating Partnership and its Subsidiaries from March 31, 
1993 until the end of the calendar  quarter covered in the Operating  
Partnership's Annual  Report on Form 10-K or Quarterly Report on  Form 10-Q, 
as the



                                        10
<PAGE>

case may be, most recently filed with the Commission (or, if such filing is 
not permitted under the Exchange Act, with the Trustee) prior to such 
distribution; provided, however, that the foregoing limitation shall not 
apply to any distribution which is necessary to maintain the Company's status 
as a REIT under the Internal Revenue Code of 1986, as amended (the "Code"), 
if the aggregate principal amount of all outstanding Debt of the Operating 
Partnership and its Subsidiaries on a consolidated basis at such time is less 
than 60% of Adjusted Total Assets (Section 1005).

     Notwithstanding the foregoing, the Operating Partnership will not be 
prohibited from making the payment of any distribution within 30 days of the 
declaration thereof if at such date of declaration such payment would have 
complied with the provisions of the immediately preceding paragraph (Section 
1005).

     EXISTENCE.  Except as permitted under "Merger, Consolidation or Sale," 
the Operating Partnership will do or cause to be done all things necessary to 
preserve and keep in full force and effect its existence, rights and 
franchises; provided, however, that the Operating Partnership shall not be 
required to preserve any right or franchise if it determines that the 
preservation thereof is no longer desirable in the conduct of the business of 
the Operating Partnership, and that the loss thereof is not disadvantageous 
in any material respect to the Holders of the Debt Securities.

     MAINTENANCE OF PROPERTIES.  The Operating Partnership will cause all of 
its properties used or useful in the conduct of its business or the business 
of any Subsidiary to be maintained and kept in good condition, repair and 
working order and supplied with all necessary equipment and will cause to be 
made all necessary repairs, renewals, replacements, betterments and 
improvements thereof, all as in the judgment of the Operating Partnership may 
be necessary so that the business carried on in connection therewith may be 
properly and advantageously conducted at all times; provided, however, that 
the Operating Partnership shall not be prevented from selling or otherwise 
disposing for value its properties in the ordinary course of business 
(Section 1007).

     INSURANCE.  The Operating Partnership will and will cause each of its 
Subsidiaries to, keep all of its insurable properties insured against loss or 
damage at least equal to their then fully insurable value with financially 
sound and reputable insurance companies (Section 1008).

     PAYMENT OF TAXES AND OTHER CLAIMS.  The Operating Partnership will pay 
or discharge or cause to be paid or discharged, before the same shall become 
delinquent, (i) all taxes, assessments and governmental charges levied or 
imposed upon it or any Subsidiary or upon the income, profits or property of 
the Operating Partnership or any Subsidiary, and (ii) all lawful claims for 
labor, materials and supplies which, if unpaid, might by law become a lien 
upon the property of the Operating Partnership or any Subsidiary; provided, 
however, that the Operating Partnership shall not be required to pay or 
discharge or cause to be paid or discharged any such tax, assessment, charge 
or claim whose amount, applicability or validity is being contested in good 
faith by appropriate proceedings (Section 1009).

     PROVISION OF FINANCIAL INFORMATION.  The Holders of the Debt Securities 
will be provided with copies of the annual reports and quarterly reports of 
the Operating Partnership.  Whether or not the Operating Partnership is 
subject to Section 13 or 15(d) of the Exchange Act, the Operating Partnership 
will, to the extent permitted under the Exchange Act, file with the 
Commission the annual reports, quarterly reports and other documents which 
the Operating Partnership would have been required to file with the 
Commission pursuant to such Section 13 or 15(d) (the "Financial Statements") 
if the Operating Partnership were so subject, such documents to be filed with 
the Commission on or prior to the respective dates (the "Required Filing 
Dates") by which the Operating Partnership would have been required so to 
file such documents if the Operating Partnership were so subject.  The 
Operating Partnership will also in any event (x) within 15 days of each 
Required Filing Date (i) transmit by mail to all Holders of Debt Securities, 
as their names and  addresses appear in the Security Register, without cost 
to such Holders, copies of the annual reports and quarterly reports which the 
Operating Partnership would have been required to file with the Commission 
pursuant to Section 13 or 15(d) of the Exchange Act if the Operating 
Partnership were subject to such Sections and (ii) file with the Trustee 
copies of the annual reports, quarterly reports and other documents which the 
Operating Partnership would have been required to file with the Commission 
pursuant to Section 13 or 15(d) of the Exchange Act if the Operating 
Partnership were subject to such Sections and (y) if filing such documents by 
the Operating Partnership with the Commission is not permitted under the 
Exchange Act, promptly upon written request and payment of the reasonable 
cost of duplication and delivery, supply copies of such documents to any 
prospective Holder (Section 1010).

corresponding to the remaining life to maturity, as of the payment date of 
the principal being redeemed or paid.  If no maturity exactly corresponds to 
such maturity, yields for the two published maturities most closely 
corresponding to such maturity shall be calculated pursuant to the 
immediately preceding sentence and the Reinvestment Rate shall be 
interpolated or extrapolated from such yields on a straight-line basis, 
rounding in each of such relevant periods to the nearest month.  For the

EVENTS OF DEFAULT, NOTICE AND WAIVER

     The Indenture provides that the following events are "Events of Default" 
with respect to the Debt Securities issued thereunder:  (i) default for 30 
days in the payment of any interest on any Debt Security of such series; (ii) 
default in the payment of the principal of (or premium, if any,) on any Debt 
Security of such series at its maturity; (iii) default in the performance, or 
breach, of any other covenant or warranty of the Operating Partnership 
contained in the Indenture (other than a covenant added to the Indenture 
solely for the benefit of a series of Debt Securities issued thereunder other 
than such series), continued for 60 days after written notice as provided in 
the applicable Indenture; (iv) an event of default under any Debt, as defined 
in any indenture or instrument evidencing such Debt, whether such 
indebtedness now exists or shall hereinafter be created, the repayment of 
which the Operating Partnership is directly responsible or liable as obligor 
or guarantor on a full recourse basis, for outstanding indebtedness for 
borrowed money in, or a guarantee for, a principal amount in excess of 
$10,000,000, shall happen and be continuing and such indebtedness shall have 
been accelerated so that the same shall be or become due and payable prior to 
the date on which the same would otherwise have become due  and payable or 
the  Operating Partnership shall  default in the payment at final maturity of 
outstanding indebtedness for borrowed




                                        13
<PAGE>

money in a principal amount in excess of $10,000,000, without such 
indebtedness having been discharged, or such acceleration having been 
rescinded or annulled; and (v) certain events of bankruptcy, insolvency or 
reorganization, or court appointment of a receiver, liquidator or trustee of 
the Operating Partnership, any Significant Subsidiary or any of their 
property and any other Event of Default (Section 501).

     If an Event of Default under the Indenture with respect to Debt 
Securities of any series at the time Outstanding occurs and is continuing, 
then in every such case the Trustee or the Holders of not less than 25% of 
the principal amount of the Outstanding Debt Securities of that series will 
have the right to declare the principal of (or, if the Debt Securities of 
that series are Original Issue Discount Securities or Indexed Securities, 
such portion of the principal amount as may be specified in the terms 
thereof) and premium (if any) on all of the Debt Securities of that series to 
be due and payable immediately by written notice thereof to the Operating 
Partnership (and to the Trustee if given by the Holders).  However, at any 
time after such a declaration of acceleration with respect to Debt Securities 
of such series (or of all Debt Securities then Outstanding under the 
Indenture, as the case may be) has been made, but before a judgment or decree 
for payment of the money due has been obtained by the Trustee, the Holders of 
not less than a majority in principal amount of Outstanding Debt Securities 
of such series (or of all Debt Securities then Outstanding under the 
Indenture, as the case may be) may rescind and annul such declaration and its 
consequences if (i) the Operating Partnership shall have paid or deposited 
with the Trustee all required payments of the principal of and premium (if 
any) and interest on the Outstanding Debt Securities of such series (or of 
all Debt Securities then Outstanding under the Indenture, as the case may 
be), plus certain fees, expenses, disbursements and advances of the Trustee 
and (ii) all Events of Default, other than the non-payment of accelerated 
principal or interest, with respect to the Debt Securities of such series (or 
of all Debt Securities then Outstanding under the Indenture, as the case may 
be) have been cured or waived as provided in the Indenture (Section 502).  
The Indenture also provides that the Holders of not less than a majority in 
principal amount of the Outstanding Debt Securities of any series (or of all 
Debt Securities then Outstanding under the Indenture, as the case may be) may 
waive any past default with respect to such series and its consequences, 
except a default (x) in the payment of the principal of and premium (if any) 
or interest on any Debt Security of such series or (y) in respect of a 
covenant or provision contained in the Indenture that cannot be modified or 
amended without the consent of the Holder of each Outstanding Debt Security 
affected thereby (Section 513).

     The Trustee will be required to give notice to the Holders of Debt 
Securities within 90 days of a default under the Indenture, unless such 
default shall have been cured or waived; provided, however, that the Trustee 
may withhold notice to the Holders of any series of Debt Securities of any 
default with respect to such series (except a default in the payment of the 
principal of and premium (if any) or interest on any Debt Security) if and so 
long as the Responsible Officers of the Trustee consider such withholding to 
be in the interest of such Holders (Section 601).

     The Indenture provides that no Holders of Debt Securities of any series 
may institute any proceedings, judicial or otherwise, with respect to the 
Indenture or for any remedy thereunder, except in the case of failure of the 
Trustee, for 60 days, to act after it has received a written request to 
institute proceedings in respect of an Event of Default from the Holders of 
not less than 25% in principal amount of the Outstanding Debt Securities of 
such series, as well as an offer of indemnity reasonably satisfactory to it 
(Section 507).  This provision will not prevent, however, any Holder of Debt 
Securities from instituting suit for the enforcement of payment of the 
principal of and premium (if any) and interest on such Debt Securities at the 
respective due dates thereof (Section 508).

     Subject to provisions in the Indenture relating to its duties in case of 
default, the Trustee is under no obligation to exercise any of its rights or 
powers under the Indenture at the request or direction of any Holders of any 
series of Debt Securities then Outstanding under the Indenture, unless such 
Holders shall have offered to the Trustee reasonable security or indemnity 
(Section 602).  The Holders of not less than a majority in principal amount 
of the Outstanding Debt Securities of any series (or of all Debt Securities 
then Outstanding under the Indenture, as the case may be) shall have the 
right to direct the time, method and place of conducting any proceeding for 
any remedy available to the Trustee, or of exercising any trust or power 
conferred upon the Trustee.  However, the Trustee may refuse to follow any 
direction which is in conflict with any law or the Indenture, which may 
involve the Trustee in personal liability or which may be unduly prejudicial 
to the Holders of Debt Securities of such series not joining therein (Section 
512).

     Within 120 days after the close of each fiscal year, the Operating 
Partnership must deliver to the Trustee a certificate, signed by one of 
several specified officers of the Company as to such officer's knowledge of 
the Operating Partnership's compliance with all conditions and covenants 
under the Indenture, and, in the event of any noncompliance, specifying each 
such noncompliance and the nature and status thereof.

MODIFICATION OF THE INDENTURE

     Modifications and amendments of the Indenture may be made only with the 
consent of the Holders of not less than a majority in principal amount of all 
Outstanding Debt Securities of each series issued under the Indenture which 
are affected by such modification or amendment; provided, however, that no 
such modification or amendment may, without the consent of the Holder of each 
such Debt Security affected thereby, (i) change the Stated Maturity of the 
principal of, or any installment of principal of and premium (if any) or 
interest on, any such Debt Security; (ii) reduce the principal amount of, or 
the rate or amount of interest on, or premium payable upon the redemption of 
any such Debt Security; (iii) change the Place of Payment, or the currency, 
for payment of principal of any Debt Security or any premium or interest on 
any such Debt Security; (iv) impair the right to institute suit for the 
enforcement of any payment on or with respect to any such Debt Security; (v) 
reduce the above-stated percentage of Outstanding Debt Securities of any 
series necessary to modify or amend the Indenture, to waive compliance with 
certain provisions thereof or certain defaults and consequences thereunder or 
to reduce the quorum or voting requirements set forth in the Indenture; or 
(vi) modify any of the foregoing provisions or any of the provisions relating 
to the waiver of certain past defaults or certain covenants, except to 
increase the required percentage to effect such action or to provide that 
certain other provisions may not be modified or waived without the consent of 
the Holder of such Debt Security or (vii) adversely modify or affect (in any 
manner adverse to the Holders) the terms and conditions of the obligations of 
the Operating Partnership in respect of the due and punctual payment of the 
principal of and premium (if any), or interest on the Debt Securities 
(Section 902).

     The Holders of not less than a majority in principal amount of 
Outstanding Debt Securities of each series affected thereby have the right to 
waive compliance by the Operating Partnership with certain covenants in the 
Indenture (Section 1013).

     Modifications and amendments of the Indenture may be permitted to be 
made by the Operating Partnership and the Trustee without the consent of any 
Holders of Debt Securities for any of the following purposes:  (i) to 
evidence the succession of another Person to the Operating Partnership as 
obligor under the Indenture; (ii) to add to the covenants of the Operating 
Partnership for the benefit of the Holders of all or any series of Debt 
Securities or to surrender any right or power conferred upon the Operating 
Partnership in Indenture; (iii) to add Events of Default for the benefit of 
the Holders of all or any series of Debt Securities; (iv) to change or 
eliminate any of the provisions of the Indenture, provided that any such 
change or elimination shall become effective only when there is no Debt 
Security Outstanding of any series created prior to the modification or 
amendment which is entitled to the benefit of such provision; (v) to secure 
the Debt Securities; (vi) to provide for the acceptance of appointment by a 
successor Trustee or facilitate the administration of the trusts under the 
Indenture by more than one Trustee; (vii) to cure any ambiguity, defect or 
inconsistency in the Indenture, provided that such action shall not adversely 
affect the interests of Holders of Debt Securities of any series issued under 
the Indenture in any material respect; or (viii) to supplement any of the 
provisions of the Indenture to the extent necessary to permit or facilitate 
defeasance and discharge of any series of such Debt Securities, provided that 
such action shall not adversely affect the interests of the Holders of the 
Debt Securities of any series in any material respect (Section 901).

     The Indenture provides that in determining whether the Holders of the 
requisite principal amount of Outstanding Debt Securities of a series have 
given any request, demand, authorization, direction, notice, consent or 
waiver thereunder or whether a quorum is present at a meeting of Holders of 
Debt Securities, Debt Securities owned by the Operating Partnership, or any 
other obligor upon the Debt Securities or any affiliate of the Operating 
Partnership, Company or of such other obligor shall be disregarded.

     The Indenture contains provisions for convening meetings of the Holders 
of Debt Securities of a series (Section 1501).  A meeting may be called at 
any time by the Trustee, and also, upon request, by the Operating Partnership 
or by the Holders of at least 10% in principal amount of the Outstanding Debt 
Securities of such series, or in any such case, upon notice given as provided 
in the Indenture (Section 1502).  Except for any consent that must be given 
by the Holder of each Debt Security affected by certain modifications and 
amendments of the Indenture, any resolution presented at a meeting or 
adjourned meeting duly reconvened at which a quorum is present may be adopted 
by the affirmative vote of the Holders of a majority in principal amount of 
the Outstanding Debt Securities of that series; provided, however, that, 
except as referred to above, any resolution with respect to any request, 
demand, authorization, direction, notice, consent, waiver or other action 
that may be made, given or taken by the Holders of a specified percentage, 
which is less than a majority, in principal amount of the Outstanding Debt 
Securities of a series may be adopted at a meeting or adjourned meeting duly 
reconvened at which a quorum is present by the affirmative vote of the 
Holders of such specified percentage in principal amount of the Outstanding 
Debt Securities of that series.  Any resolution passed or decision taken at 
any meeting of Holders of Debt Securities of any series duly held in 
accordance with the Indenture will be binding on all Holders of Debt 
Securities of that series.  The quorum at any meeting called to adopt a 
resolution, and at any reconvened meeting, will be Persons holding or 
presenting a majority in principal amount of the Outstanding Debt Securities 
of a series; provided, however, that if any action is to be taken at such 
meeting with respect to a consent or waiver which may be given by the Holders 
of not less than a 




                                        15
<PAGE>

specified percentage in principal amount of the Outstanding Debt Securities 
of a series, the Persons holding or representing such specified percentage in 
principal amount of the Outstanding Debt Securities will constitute a quorum 
(Section 1504).

     Notwithstanding the foregoing provisions, if any action is to be taken 
at a meeting of Holders of Debt Securities of any series with respect to any 
request, demand, authorization, direction, notice, consent, waiver or other 
action that the Indenture expressly provides may be made, given or taken by 
the Holders of a specified percentage in principal amount of all Outstanding 
Debt Securities affected thereby, or of the Holders of such series and one or 
more additional series:  (i) there shall be no minimum quorum requirement for 
such meeting; and (ii) the principal amount of the Outstanding Debt 
Securities of such series that vote in favor of such request, demand, 
authorization, direction, notice, consent, waiver or other action shall be 
taken into account in determining whether such request, demand, 
authorization, direction, notice, consent, waiver or other action has been 
made, given or taken under the Indenture (Section 1504).

DISCHARGE, DEFEASANCE AND COVENANT DEFEASANCE

     The Operating Partnership may discharge certain obligations to Holders 
of any series of Debt Securities that either have become due and payable or 
will become due and payable within one year (or scheduled for redemption 
within one year) by irrevocably depositing with the Trustee, in trust, funds 
in an amount sufficient to pay and discharge the entire indebtedness on such 
Debt Securities in respect of principal and premium (if any) and interest to 
the date of such deposit (if such Debt Securities have become due and 
payable) or to the Stated Maturity or Redemption Date, as the case may be 
(Section 1401).

     The Indenture provides that, if the provisions of Article Fourteen of 
the Indenture are made applicable to the Debt Securities of or within any 
series pursuant to Section 301 of the Indenture, the Operating Partnership 
may elect either (i) to defease and be discharged from any and all 
obligations with respect to such Debt Securities (except for the obligations 
to register the transfer or exchange of such Debt Securities, to replace 
temporary or mutilated, destroyed, lost or stolen Debt Securities, to 
maintain an office or agency in respect of such Debt Securities and to hold 
moneys for payment in trust) ("defeasance") (Section 1402) or (ii) to be 
released from its obligations with respect to such Debt Securities under 
Sections 1004 to 1010, inclusive, of the Indenture (being the restrictions 
described under "Certain Covenants") and any omission to comply with such 
obligations shall not constitute a default or an Event of Default with 
respect to such Debt Securities ("covenant defeasance") (Section 1403), in 
either case upon the irrevocable deposit by the Operating Partnership with 
the Trustee, in trust, of an amount, in cash or Government Obligations (as 
defined below), or both, which through the scheduled payment of principal and 
interest in accordance with their terms will provide money in an amount 
sufficient without reinvestment to pay the principal of and premium (if any) 
and interest on such Debt Securities on the scheduled due dates therefor.

     Such a trust may only be established if, among other things, the 
Operating Partnership has delivered to the applicable Trustee an Opinion of 
Counsel (as specified in the Indenture) to the effect that the Holders of 
such Debt Securities will not recognize income, gain or loss for U.S. federal 
income tax purposes as a result of such defeasance or covenant defeasance and 
will be subject to U.S. federal income tax on the same amounts, in the same 
manner and at the same times as would have been the case if such defeasance 
or covenant defeasance had not occurred, and such Opinion of Counsel, in the 
case of defeasance, must refer to and be based upon a ruling of the Internal 
Revenue Service or a change in applicable United States federal income tax 
law occurring after the date of the Indenture (Section 1404).

     "Government Obligations" means securities which are (i) direct 
obligations of the United States of America, for the payment of which its 
full faith and credit is pledged or (ii) obligations of a Person controlled 
or supervised by and acting as an agency or instrumentality of the United 
States of America, the timely payment of which is unconditionally guaranteed 
as a full faith and credit obligation by the United States of America, which 
are not callable or redeemable at the option or the issuer thereof, and shall 
also include a depository receipt issued by a bank or trust company as 
custodian with respect to any such Government Obligation or specific payment 
of interest on or principal of any such Government Obligation held by such 
custodian for the account of the Holder of a depository receipt, provided 
that (except as required by law) such custodian is not authorized to make any 
deduction from the amount payable to the Holder of such depository receipt 
from any amount received by the custodian in respect of the Government 
Obligation or the specific payment of interest on or principal of the 
Government Obligation evidenced by such depository receipt.

     In the event the Operating Partnership effects covenant defeasance with 
respect to any Debt Securities, and such Debt Securities are declared due and 
payable because of the occurrence of any Event of Default other than the 
Event of Default described in clause (iii) under "Events of Default, Notice 
and Waiver" with respect to Sections 1004 to 1010, inclusive, of the 
Indenture (which Sections would no longer be applicable to such Debt 
Securities), the amount of Government Obligations on deposit with the Trustee 
will be sufficient to pay amounts due on such Debt Securities at the time of 
their Stated Maturity but may not be sufficient to pay amounts due on such 
Debt Securities at the time of the acceleration resulting from such Event of 
Default. However, the Operating 



                                        16
<PAGE>

Partnership would remain liable to make payment of such amounts due at the 
time of acceleration.

     The applicable Prospectus Supplement may further describe the 
provisions, if any, permitting such defeasance or covenant defeasance 
including any modifications to the provisions described above, with respect 
to the Debt Securities of or within a particular series.

REDEMPTION OF SECURITIES

     The Indenture provides that the Debt Securities may be redeemed at any 
time at the option of the Operating Partnership, in whole or in part, at the 
Redemption Price, except as may otherwise be provided in connection with any 
Debt Securities or series thereof.

     From and after notice has been given as provided in the Indenture, if 
funds for the redemption of any Debt Securities called for redemption shall 
have been made available on such redemption date, such Debt Securities will 
cease to bear interest on the date fixed for such redemption specified in 
such notice and the only right of the Holders of the Debt Securities will be 
to receive payment of the Redemption Price.

     Notice of any optional redemption of any Debt Securities will be given 
to Holders at their addresses, as shown in the Security Register, not more 
than 60 nor less than 30 days prior to the date fixed for redemption.  The 
notice of redemption will specify, among other items, the Redemption Price 
and the principal amount of the Debt Securities held by such Holder to be 
redeemed.

     If the Operating Partnership elects to redeem Debt Securities, it will 
notify the Trustee at lease 45 days prior to the redemption date (or such 
shorter period as satisfactory to the Trustee) of the aggregate principal 
amount of Debt Securities to be redeemed and the redemption date.  If less 
than all the Debt Securities are to be redeemed, the Trustee shall select the 
Debt Securities to be redeemed PRO RATA, by lot or in such manner as it shall 
deem fair and appropriate.

BOOK ENTRY REGISTRATION

     If the applicable Prospectus Supplement so indicates, the Debt 
Securities will be represented by one or more certificates (the "Global 
Notes").  The Global Notes representing Debt Securities will be deposited 
with, or on behalf of, The Depository Trust Company ("DTC") or other 
successor depository appointed by the Operating Partnership (DTC or such 
other depository is herein referred to as the "Depository") and registered in 
the name of the Depository or its nominee.  Unless and until it is exchanged 
in whole or in part for Debt Securities in definitive form under the limited 
circumstances described below, the Global Note may not be transferred except 
as a whole (i) by DTC for the Global Note to a nominee of DTC, (ii) by a 
nominee of DTC to DTC or another nominee of DTC, or (iii) by DTC or any such 
nominee to a successor of DTC or a nominee of such successor.

     DTC currently limits the maximum denomination of any single Global Note 
to $150,000,000.  Therefore, for purposes hereof, "Global Note" refers to the 
Global Note or Global Notes representing the entire issue of Debt Securities 
of a particular series.

     Ownership of beneficial interests in the Global Note will be limited to 
persons that have accounts with DTC for the Global Note ("participants") or 
persons that may hold interests through participants.  Upon the issuance of 
the Global Note, DTC will credit, on its book-entry registration and transfer 
system, the participants' accounts with the respective principal amounts of 
the Debt Securities represented by the Global Note beneficially owned by such 
participants.  Ownership of beneficial interests in the Global Note will be 
shown on, and the transfer of such ownership interests will be effected only 
through, records maintained by DTC (with respect to interests of 
participants) and on the records of participants (with respect to interests 
of persons holding through participants).  The laws of some states may 
require that certain purchasers of securities take physical delivery of such 
securities in definitive form.  Such limits and such laws may impair the 
ability to own, transfer, or pledge beneficial interests in the Global Note.

     So long as DTC or its nominee is the registered owner of the Global 
Note, DTC or such nominee, as the case may be, will be considered the sole 
owner or holder of the Debt Securities represented by the Global Note for all 
purposes under the Indenture.  Except as set forth below, owners of 
beneficial interests in the Global Note will not be entitled to have the Debt 
Securities represented by the Global Note registered in their names, will not 
receive or be entitled to receive physical delivery of the Debt Securities in 
definitive form, and will not be considered the owners or holders thereof 
under the Indenture. Accordingly, each person owning a beneficial interest in 
the Global Note must rely on the procedures of DTC and, if such person is not 
a participant, on the procedures of the participant through which such 
person owns its interest, to exercise any rights of a holder under the 
Indenture. The Operating 




                                        17
<PAGE>

Partnership understands that under existing industry practices, if the 
Operating Partnership requests any action of holders or if an owner of a 
beneficial interest in the Global Note desires to give or take any action 
that a holder is entitled to give or take under the Indenture, DTC would 
authorize the participants holding the relevant beneficial interests to give 
or take such action, and such participants would authorize beneficial owners 
owning through such participants to give or take such action or would 
otherwise act upon the instructions of beneficial owners holding through them.

     Principal and interest payments on Debt Securities represented by the 
Global Note will be made to DTC or its nominee, as the case may be, as the 
registered owner of the Global Note.  None of the Operating Partnership, the 
Trustee, or any other agent of the Operating Partnership or agent of the 
Trustee will have any responsibility or liability for any aspect of the 
records relating to or payments made on account of beneficial ownership 
interests in the Global Note or for maintaining, supervising, or reviewing 
any records relating to such beneficial ownership interests.

     The Operating Partnership expects that DTC, upon receipt of any payment 
of principal or interest in respect of the Global Note, will immediately 
credit participants' accounts with payments in amounts proportionate to their 
respective beneficial interests in the Global Note as shown on the records of 
DTC.  The Operating Partnership also expects that payments by participants to 
owners of beneficial interests in the Global Note held through such 
participants will be governed by standing customer instructions and customary 
practices, as is not the case with the securities held for the accounts of 
customers in bearer form or registered in "street name," and will be the 
responsibility of such participants.

     If DTC is at any time unwilling or unable to continue as depository for 
the Debt Securities and the Operating Partnership fails to appoint a 
successor Depository registered as a clearing agency under the Exchange Act 
within 90 days, the Operating Partnership will issue the Debt Securities in 
definitive form in exchange for the Global Note.  Any Debt Securities issued 
in definitive form in exchange for the Global Note will be registered in such 
name or names, and will be issued in denominations of $1,000 and such 
integral multiples thereof, as DTC shall instruct the Trustee.  It is 
expected that such instructions will be based upon directions received by DTC 
from participants with respect to ownership of beneficial interests in the 
Global Note.

     DTC has advised the Operating Partnership of the following information 
regarding DTC.  DTC is a limited-purpose trust company organized under the 
Banking Laws of the State of New York, a member of the Federal Reserve 
System, a "clearing corporation" within the meaning of the New York Uniform 
Commercial Code, and a "clearing agency" registered pursuant to the 
provisions of Section 17A of the Exchange Act.  DTC was created to hold 
securities of its participants and to facilitate the clearance and settlement 
of transactions among its participants in such securities through electronic 
book-entry changes in accounts of the participants, thereby eliminating the 
need for physical movement of securities certificates.  DTC's participants 
include securities brokers and dealers, banks, trust companies, clearing 
corporations, and certain other organizations, some of which (and/or their 
representatives) own DTC.  Access to DTC book-entry system is also available 
to others, such as banks, brokers, dealers, and trust companies that clear 
through or maintain a custodial relationship with a participant, either 
directly or indirectly.

SAME-DAY SETTLEMENT

     Unless the applicable Prospectus Supplement so indicates, settlement for
the Debt Securities will be made by the underwriters, dealers or agents in
immediately available funds and all payments of principal and interest on the
Debt Securities will be made by the Operating Partnership in immediately
available funds.

     Secondary trading in long-term notes and debentures of corporate issuers is
generally settled in clearinghouse or next-day funds.  In contrast, the Debt
Securities subject to settlement in immediately available funds will trade in
DTC's Same-Day Funds Settlement System until maturity or until the Debt
Securities are issued in certificated form, and secondary market trading
activity in such Debt Securities will therefore be required by DTC to settle in
immediately available funds.  No assurance can be given as to the effect, if
any, of settlement in immediately available funds on trading activity in the
Debt Securities.

                             PLAN OF DISTRIBUTION

     The Operating Partnership may sell the Debt Securities to one or more
underwriters for public offering and sale by them or may sell the Debt
Securities to investors directly or through agents.  Any such underwriter or
agent involved in the offer and sale of the Debt Securities will be named in the
applicable Prospectus Supplement.

     Underwriters may offer and sell the Debt Securities at a fixed price or
prices, which may be changed, at prices related to the prevailing market prices
at the time of sale or at negotiated prices.  The Operating Partnership may,
from time to time, authorize underwriters acting as the Operating Partnership's
agents to offer and sell the Debt Securities upon the terms and conditions as
are set forth in the applicable Prospectus Supplement.  In connection with the
sale of the Debt Securities, underwriters may be deemed to have received
compensation from the Operating Partnership in the form of underwriting
discounts or commissions and may also receive commissions from purchasers of the
Debt Securities for whom they may act as agent.  Underwriters may sell Debt
Securities to or through dealers, and such dealers may receive compensation in
the form of discounts, concessions or commissions from the underwriters and/or
commissions from the purchasers for whom they may act as agent.

     Any underwriting compensation paid by the Operating Partnership to
underwriters or agents in connection with the offering of the Debt Securities,
and any discounts, concessions or commissions allowed by underwriters to
participating dealers, will be set forth in the applicable Prospectus
Supplement.  Underwriters, dealers and agents participating in the distribution
of the Debt Securities may be deemed to be underwriters, and any discounts and
commissions received by them and any profit realized by them on resale of the
Debt Securities may be deemed to be underwriting discounts and commissions,
under the Securities Act.  Underwriters, dealers and agents may be entitled,
under agreements entered into with the Operating Partnership, to indemnification
against and contribution toward certain civil liabilities, including liabilities
under the Securities Act.

     If so indicated in the applicable Prospectus Supplement, the Operating
Partnership will authorize underwriters or other persons acting as the Operating
Partnership's agents to solicit offers by certain institutions to purchase Debt
Securities from the Operating Partnership at the public offering price set forth
in such Prospectus Supplement pursuant to Delayed Delivery Contracts
("Contracts") providing for payment and delivery on the date or dates stated in
such Prospectus Supplement.  Each Contract will be for an amount not less than,
and the aggregate principal amount of Debt Securities sold pursuant to Contracts
shall be not less nor more than, the respective amounts stated in the applicable
Prospectus Supplement.  Institutions with whom Contracts, when authorized, may
be made include commercial and savings banks, insurance companies, pension
funds, investment companies, educational and charitable institutions, and other
institutions but will in all cases be subject to the approval of the Operating
Partnership.  Contracts will not be subject to any conditions except (i) the
purchase by an institution of the Debt Securities covered by its Contracts shall
not at the time of delivery be prohibited under the laws of any jurisdiction in
the United States to which such institution is subject, and (ii) if the Debt
Securities are being sold to underwriters, the Operating Partnership shall have
sold to such underwriters, the total principal amount of the Debt Securities
less the principal amount thereof covered by Contracts.

     Certain of the underwriters and their affiliates may be customers of,
engage in transactions with, and perform services for the Operating Partnership
and its Subsidiaries in the ordinary course of business.
