S-4 5 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 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 March 31, 1998, owned approximately 91% 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 March 31, 1998, the Operating Partnership owned or had interests in a portfolio of 502 multifamily properties (individually a "Property" and collectively the "Properties") containing 143,348 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 March 31, 1998, the Operating Partnership has acquired, directly or indirectly, interests in an additional 453 Properties containing 127,164 units for a total purchase price of approximately $7.0 billion, including the assumption of approximately $2.1 billion of mortgage indebtedness and unsecured notes. Since the EQR IPO and through March 31, 1998, the Operating Partnership has disposed of 20 of its properties and a portion of one of its Properties containing an aggregate of 5,541 units and a vacant land parcel for a total sales price of approximately $146.5 million and the release of mortgage indebtedness in the amount of approximately $20.5 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 March 31, 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, 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; 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. S-5 6 RECENT DEVELOPMENTS ACQUISITIONS From January 1, 1998 through March 31, 1998, the Operating Partnership acquired 15 Properties containing an aggregate of 3,387 units at a total purchase price of approximately $225.2 million (including the assumption of mortgage indebtedness of approximately $93.6 million). The Operating Partnership funded the cash portion of these acquisitions primarily with proceeds from previous securities issuances by the Company. See "Securities Issuances" below. PROBABLE ACQUISITIONS As of March 31, 1998, the Operating Partnership had entered into contracts with unaffiliated sellers to acquire four additional properties containing 1,622 units which are located in four states (collectively, the "Properties Under Contract"). The total combined purchase price for the Properties Under Contract is approximately $184.1 million, including the assumption of approximately $48.5 million of mortgage indebtedness. There can be no assurance that these four 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 the net proceeds of the Offering, its working capital, its $500 million unsecured line of credit (the "Line of Credit") and/or proceeds from previous securities issuances by the Company. 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 March 31, 1998, the Operating Partnership had entered into contracts with various unaffiliated sellers to acquire five additional properties under contract (the "Additional Properties Under Contract") for a total combined purchase price of approximately $93.7 million, including the assumption of approximately $26.3 million of mortgage indebtedness. These Additional Properties Under Contract contain 1,205 units and are located in five 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 with the net proceeds of the Offering and/or from the Operating Partnership's Line of Credit. There can be no 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 March 31, 1998, the Operating Partnership was also negotiating with various sellers for the acquisition of 63 additional properties (the "Properties Under Negotiation") containing 14,238 units for a purchase price of approximately $970.2 million, including the assumption of approximately $381.6 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. S-6 7 DISPOSITIONS Since January 1, 1998, the Operating Partnership disposed of its interests in two properties containing 506 units for an aggregate sales price of approximately $16.7 million. The net proceeds of these dispositions were or will be used for the acquisition of additional properties. SECURITIES ISSUANCES Since January 1, 1998, the Company has raised an aggregate of approximately $314 million pursuant to five separate public offerings of EQR's common shares of beneficial interest. In addition, from January 1, 1998, through March 31, 1998, the Company has raised approximately $31.7 million pursuant to its Distribution Reinvestment and Share Purchase Plan. S-7 8 USE OF PROCEEDS The net proceeds to the Operating Partnership from the Offering are estimated at $305,805,000 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 for the acquisition of additional multifamily properties and for working capital purposes. 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 March 31, 1998, the Operating Partnership owned or had interests in a portfolio of 502 Properties containing 143,348 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 Properties consists 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, 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; 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 satisfaction surveys, (ii) surveying residents that move out of the Properties, and (iii) surveying prospective tenants who select alternative housing. S-8 9 THE PROPERTIES As of March 31, 1998, the Operating Partnership owned or had interests in a portfolio of 502 Properties located in 35 states containing 143,348 apartment units with the largest having 1,420 units and the smallest having 40 units. The average number of units per Property was approximately 286. The units are typically contained in a series of two-story buildings. As of March 31, 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.

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. 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 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 outstanding. 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 December 31, 1997, such mortgages aggregated approximately $1.6 billion. As of December 31, 1997, the outstanding indebtedness of the Operating Partnership with which the Notes will rank equally was approximately $1.4 billion (net of a $2.5 million discount and including an $8.2 million premium). As of December 31, 1997, the Operating Partnership's total debt was approximately $2.9 billion, and on a pro forma basis giving effect to this Offering, the total outstanding indebtedness of the Operating Partnership and its Subsidiaries was approximately $3.2 billion. Subject to certain limitations set forth in the Indenture, and as described under "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 senior unsecured obligations of the Operating Partnership and will be limited to $300,000,000 in aggregate principal amount. The Notes will mature on April 13, 2015 (the "Stated Maturity Date"). Except in the limited circumstances described herein, the Notes are not subject to redemption by the Operating Partnership prior to their Stated Maturity Date. See "--Redemption" below. The Notes will bear interest at the annual interest rate of 6.63% to April 13, 2005 (the "Remarketing Date"). If the Remarketing Dealer elects to remarket the Notes, except in the limited circumstances described herein, (i) the Notes will be subject to mandatory tender to the Remarketing Dealer at 100% of the principal amount thereof for remarketing on the Remarketing Date, on the terms and subject to the conditions described herein, and (ii) on and after the Remarketing Date, the Notes will bear interest at the rate determined by the Remarketing Dealer in accordance with the procedures set forth below (the "Interest Rate to Maturity"). See "--Tender of Notes; Remarketing" below. Under the circumstances described below, the Notes are subject to redemption by the Operating Partnership from the Remarketing Dealer on the Remarketing Date. See "--Redemption" below. If the Remarketing Dealer for any reason does not purchase all tendered Notes on the Remarketing Date or elects not to remarket the Notes, or in certain other limited circumstances described herein, the Operating Partnership will be required to repurchase the Notes as a whole from the Beneficial Owners thereof on the Remarketing Date, at 100% of the principal amount thereof plus accrued interest, if any. See "--Repurchase" below. The Notes will bear interest from April 13, 1998, payable semiannually on April 13 and October 13 of each year (each, an "Interest Payment Date"), commencing October 13, 1998, to the persons in whose names the Notes are registered on the fifteenth calendar day (whether or not a Business Day) immediately preceding the related Interest Payment Date (each, a "Record Date"). Interest on the Notes will be computed on the basis of a 360-day year of twelve 30-day months. "Business Day" means any day, other than a Saturday or Sunday, that is neither a legal holiday nor a day on which banking institutions in The City of New York are authorized or required by law, regulation or executive order to close. Interest payable on any Interest Payment Date and at the Remarketing Date and the Stated Maturity Date or date of earlier redemption or repurchase shall be the amount of interest accrued from and including the next preceding Interest Payment S-13 14 Date in respect of which interest has been paid or duly provided for (or from and including April 13, 1998, if no interest has been paid or duly provided for) with respect to the Notes to but excluding such Interest Payment Date or the Stated Maturity Date or date of redemption or repurchase, as the case may be. If any Interest Payment Date or the Stated Maturity Date or date of redemption or repurchase of Notes falls on a day that is not a Business Day, the payment shall be made on the next Business Day with the same force and effect as if it were made on the date such payment was due and no interest shall accrue on the amount so payable for the period from and after such Interest Payment Date or the Stated Maturity Date or date of earlier redemption or repurchase, as the case may be. The Notes will be issued in denominations of $1,000 and integral multiples thereof. TENDER OF NOTES; REMARKETING The following description sets forth the terms and conditions of the remarketing of the Notes, if the Remarketing Dealer elects to purchase the Notes and remarkets the Notes on the Remarketing Date. Mandatory Tender. Provided that the Remarketing Dealer gives notice to the Operating Partnership and the Trustee on a Business Day not later than five Business Days prior to the Remarketing Date of its intention to purchase the Notes for remarketing (the "Notification Date"), each Note will be automatically tendered, or deemed tendered, to the Remarketing Dealer for purchase on the Remarketing Date, except in the circumstances described under "--Repurchase" or "-- Redemption" below. The purchase price for the tendered Notes to be paid by the Remarketing Dealer will equal 100% of the principal amount thereof. See "--Notification of Results; Settlement" below. When the Notes are tendered for remarketing, the Remarketing Dealer may remarket the Notes for its own account at varying prices to be determined by the Remarketing Dealer at the time of each sale. From and after the Remarketing Date, the Notes will bear interest at the Interest Rate to Maturity. If the Remarketing Dealer elects to remarket the Notes, the obligation of the Remarketing Dealer to purchase the Notes on the Remarketing Date is subject to, among other things, the conditions that, since the Notification Date, no material adverse change in the condition of the Operating Partnership and its subsidiaries, considered as one enterprise, shall have occurred and that no Event of Default (as defined in the Indenture), or any event which, with the giving of notice or passage of time, or both, would constitute an Event of Default, with respect to the Notes shall have occurred and be continuing. If for any reason the Remarketing Dealer does not purchase all tendered Notes on the Remarketing Date, the Operating Partnership will be required to repurchase the Notes as a whole from the Beneficial Owners thereof at a price equal to the principal amount thereof plus all accrued and unpaid interest, if any, on the Notes to the Remarketing Date. See "--Repurchase" below. The Interest Rate to Maturity shall be determined by the Remarketing Dealer by 3:30 p.m., New York City time, on the third Business Day immediately preceding the Remarketing Date (the "Determination Date") to the nearest one hundred-thousandth (0.00001) of one percent per annum and will be equal to 5.507% (the "Base Rate") plus the Applicable Spread (as defined below) which will be based on the Dollar Price (as defined below) of the Notes. The Interest Rate to Maturity announced by the Remarketing Dealer, absent manifest error, shall be binding and conclusive upon the Beneficial Owners and Holders of the Notes, the Operating Partnership and the Trustee. The "Applicable Spread" will be the lowest bid indication, expressed as a spread (in the form of a percentage or in basis points) above the Base Rate, obtained by the Remarketing Dealer on the Determination Date from the bids quoted by five Reference Corporate Dealers (as defined below) for the full aggregate principal amount of the Notes at the Dollar Price, but assuming (i) an issue date equal to the Remarketing Date, with settlement on such date without accrued interest, (ii) a maturity date equal to the Stated Maturity Date of the Notes, and (iii) a stated annual interest rate, payable semiannually on each Interest Payment Date, equal to the Base Rate plus the spread bid by the applicable Reference Corporate Dealer. If fewer than five Reference Corporate Dealers bid as described above, then the Applicable Spread shall be the lowest of such bid indications obtained as described above. "Dollar Price" means, with respect to the Notes, the present value as determined by the Remarketing Dealer, as of the Remarketing Date, of the Remaining Scheduled Payments (as defined below) discounted to the Remarketing Date, on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months), at the Treasury Rate (as defined below). "Reference Corporate Dealers" means leading dealers of publicly traded debt securities of the Operating Partnership in The City of New York (which may include the Remarketing Dealer or one of its affiliates) selected by the Remarketing Dealer. S-14 15 "Treasury Rate" means, with respect to the Remarketing Date, the rate per annum equal to the semiannual equivalent yield to maturity or interpolated (on a day count basis) yield to maturity of the Comparable Treasury Issues (as defined below), assuming a price for the Comparable Treasury Issues (expressed as a percentage of its principal amount), equal to the Comparable Treasury Price (as defined below) for such Remarketing Date. "Comparable Treasury Issues" means the United States Treasury security or securities selected by the Remarketing Dealer as having an actual or interpolated maturity or maturities comparable to the remaining term of the Notes being purchased. "Comparable Treasury Price" means, with respect to the Remarketing Date, (a) the offer prices for the Comparable Treasury Issues (expressed in each case as a percentage of its principal amount) on the Determination Date, as set forth on "Telerate Page 500" (or such other page as may replace Telerate Page 500) or (b) if such page (or any successor page) is not displayed or does not contain such offer prices on such Determination Date, (i) the average of the Reference Treasury Dealer Quotations for such Remarketing Date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or (ii) if the Remarketing Dealer obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such Reference Treasury Dealer Quotations. "Telerate Page 500" means the display designated as "Telerate Page 500" on Dow Jones Markets Limited (or such other page as may replace Telerate Page 500 on such service) or such other service displaying the offer prices specified in (a) above as may replace Dow Jones Markets Limited. "Reference Treasury Dealer Quotations" means, with respect to each Reference Treasury Dealer and the Remarketing Date, the offer prices for the Comparable Treasury Issues (expressed in each case as a percentage of its principal amount) quoted to the Remarketing Dealer by such Reference Treasury Dealer by 3:30 p.m., New York City time, on the Determination Date. "Reference Treasury Dealer" means each of Credit Suisse First Boston Corporation, Lehman Brothers Inc., Merrill Lynch, Pierce, Fenner & Smith Incorporated, Morgan Stanley & Co. Incorporated and Salomon Brothers Inc (or their respective affiliates which are primary U.S. Government securities dealers) and their respective successors; provided, however, that if any of the foregoing or their affiliates shall cease to be a primary U.S. Government securities dealer in The City of New York (a "Primary Treasury Dealer"), the Remarketing Dealer shall substitute therefor another Primary Treasury Dealer. "Remaining Scheduled Payments" means, with respect to the Notes, the remaining scheduled payments of the principal thereof and interest thereon, calculated at the Base Rate only, that would be due after the Remarketing Date to and including the Stated Maturity Date, as determined by the Remarketing Dealer; provided, however, that if the Remarketing Date is not an Interest Payment Date with respect to the Notes, the amount of the next succeeding scheduled interest payment thereon, calculated at the Base Rate only, will be reduced by the amount of interest accrued thereon, calculated at the Base Rate only, to the Remarketing Date. Notification of Results-Settlement. Provided the Remarketing Dealer has previously notified the Operating Partnership and the Trustee on the Notification Date of its intention to purchase all tendered Notes on the Remarketing Date, the Remarketing Dealer will notify the Operating Partnership, the Trustee and DTC by telephone, confirmed in writing (which may include facsimile or other electronic transmission), by 4:00 p.m., New York City time, on the Determination Date, of the Interest Rate to Maturity. All of the tendered Notes will be automatically delivered to the account of the Trustee, by book-entry through DTC pending payment of the purchase price therefor, on the Remarketing Date. If the Remarketing Dealer purchases the tendered Notes on the Remarketing Date, the Remarketing Dealer will make or cause the Trustee to make payment to the DTC Participant of each tendering Beneficial Owner of Notes, by book-entry through DTC no later than the close of business on the Remarketing Date against delivery through DTC of such Beneficial Owner's tendered Notes, of 100% of the principal amount of the tendered Notes that have been purchased for remarketing by the Remarketing Dealer. If the Remarketing Dealer does not purchase all of the Notes on the Remarketing Date, it will be the obligation of the Operating Partnership to make or cause to be made such payment for the Notes, as described below under "--Repurchase." In any case, the Operating Partnership will make or cause the Trustee to make payment of interest to each Beneficial Owner of Notes due on the Remarketing Date by book-entry through DTC no later than the close of business on the Remarketing Date. S-15 16 The transactions described above will be executed on the Remarketing Date through DTC in accordance with the procedures of DTC, and the accounts of the respective DTC Participants will be debited and credited and the Notes delivered by book-entry as necessary to effect the purchases and sales thereof. Transactions involving the sale and purchase of Notes remarketed by the Remarketing Dealer on and after the Remarketing Date will settle in immediately available funds through DTC's Same-Day Funds Settlement System. The tender and settlement procedures described above, including provisions for payment by purchasers of Notes in the remarketing or for payment to selling Beneficial Owners of tendered Notes, may be modified to the extent required by DTC or to the extent required to facilitate the tender and remarketing of Notes in certificated form, if the book-entry system is no longer available for the Notes at the time of the remarketing. In addition, the Remarketing Dealer may, in accordance with the terms of the Indenture, modify the tender and settlement procedures set forth above in order to facilitate the tender and settlement process. As long as DTC's nominee holds the certificate representing any Notes in the book-entry system of DTC, no certificates for such Notes will be delivered by any selling Beneficial Owner to reflect any transfer of such Notes effected in the remarketing. In addition, under the terms of the Notes and the Remarketing Agreement (described below), the Operating Partnership has agreed that, notwithstanding any provision to the contrary set forth in the Indenture, (i) it will use its best efforts to maintain the Notes in book-entry form with DTC or any successor thereto and to appoint a successor depositary to the extent necessary to maintain the Notes in book-entry form, and (ii) it will waive any discretionary right it otherwise has under the Indenture to cause the Notes to be issued in certificated form. For further information with respect to transfers and settlement through DTC, see "Description of Debt Securities" in the accompanying Prospectus. The Remarketing Dealer. The Operating Partnership and the Remarketing Dealer are entering into a Remarketing Agreement, the general terms and provisions of which are summarized below. The Remarketing Dealer will not receive any fees or reimbursement of expenses from the Operating Partnership in connection with the remarketing. The Operating Partnership will agree to indemnify the Remarketing Dealer against certain liabilities, including liabilities under the Securities Act of 1933 (the "Securities Act"), arising out of or in connection with its duties under the Remarketing Agreement. If the Remarketing Dealer elects to remarket the Notes as described herein, the obligation of the Remarketing Dealer to purchase Notes from tendering Beneficial Owners of Notes will be subject to several conditions precedent set forth in the Remarketing Agreement, including the conditions that, since the Notification Date, no material adverse change in the condition of the Operating Partnership and its subsidiaries, considered as one enterprise, shall have occurred and that no Event of Default (as defined in the Indenture), or any event which, with the giving of notice or passage of time, or both, would constitute an Event of Default, with respect to the Notes shall have occurred and be continuing. In addition, the Remarketing Agreement will provide for the termination thereof, or redetermination of the Interest Rate to Maturity, by the Remarketing Dealer on or before the Remarketing Date, upon the occurrence of certain events as set forth in the Remarketing Agreement. No Holder or Beneficial Owner of any Notes shall have any rights or claims under the Remarketing Agreement or against the Remarketing Dealer as a result of the Remarketing Dealer not purchasing such Notes. The Remarketing Agreement will also provide that the Remarketing Dealer may resign at any time as Remarketing Dealer, such resignation to be effective ten days after the delivery to the Operating Partnership and the Trustee of notice of such resignation. In such case, it shall be the sole obligation of the Operating Partnership to appoint a successor Remarketing Dealer. The Remarketing Dealer, in its individual or any other capacity, may buy, sell, hold and deal in any of the Notes. The Remarketing Dealer 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. The Remarketing S-16 17 Dealer, 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. REPURCHASE If (i) the Remarketing Dealer for any reason does not notify the Operating Partnership of the Interest Rate to Maturity by 4:00 p.m., New York City time, on the Determination Date, or (ii) prior to the Remarketing Date, the Remarketing Dealer has resigned and no successor has been appointed on or before the Determination Date, or (iii) since the Notification Date, a material adverse change in the condition of the Operating Partnership and its subsidiaries, considered as one enterprise, shall have occurred or an Event of Default (as defined in the Indenture), or any event which, with the giving of notice or passage of time, or both, would constitute an Event of Default, with respect to the Notes shall have occurred and be continuing, or any other event constituting a termination event under the Remarketing Agreement shall have occurred, or (iv) the Remarketing Dealer elects not to remarket the Notes, or (v) the Remarketing Dealer for any reason does not purchase all tendered Notes on the Remarketing Date, the Operating Partnership will repurchase the Notes as a whole on the Remarketing Date at a price equal to 100% of the principal amount of the Notes plus all accrued and unpaid interest, if any, on the Notes to the Remarketing Date. In any such case, payment will be made by the Operating Partnership to the DTC Participant of each tendering Beneficial Owner of Notes, by book-entry through DTC no later than the close of business on the Remarketing Date against delivery through DTC of such Beneficial Owner's tendered Notes. REDEMPTION If the Remarketing Dealer elects to remarket the Notes on the Remarketing Date, the Notes will be subject to mandatory tender to the Remarketing Dealer for remarketing on such date, in each case subject to the conditions described above under "--Tender of Notes; Remarketing" and "--Repurchase" and to the Operating Partnership's right to redeem the Notes from the Remarketing Dealer as described in the next sentence. The Operating Partnership will notify the Remarketing Dealer and the Trustee, not later than the close of business on the Business Day immediately preceding the Determination Date, if the Operating Partnership irrevocably elects to exercise its right to redeem the Notes, in whole but not in part, from the Remarketing Dealer on the Remarketing Date at the Optional Redemption Price. The "Optional Redemption Price" shall be the greater of (i) 100% of the principal amount of the Notes and (ii) the sum of the present values of the Remaining Scheduled Payments thereon, as determined by the Remarketing Dealer, discounted to the Remarketing Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate, plus in either case accrued and unpaid interest from the Remarketing Date on the principal amount being redeemed to the date of redemption. If the Operating Partnership elects to redeem the Notes, it shall pay the redemption price therefor in same-day funds by wire transfer to an account designated by the Remarketing Dealer on the Remarketing Date. 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. S-17 18 CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS The following discussion summarizes certain federal income tax considerations relating to the acquisition, ownership and disposition of the Notes. The following description is for general information only, is not exhaustive of all possible tax considerations, and is not intended to be and should not be construed as tax advice. For example, this summary addresses only Notes held as capital assets by initial holders purchasing Notes at the "issue price" (generally, the first price to the public (excluding bond houses, brokers or similar persons or organizations acting as underwriters, placement agents or wholesalers) at which a substantial amount of Notes is sold for money). This summary does not purport to deal with persons in special tax situations, such as financial institutions, insurance companies, regulated investment companies, dealers in securities or currencies, persons holding the Notes as a hedge against currency risk or as a position in a "straddle" for U.S. tax purpose, persons whose functional currency is not the U.S. dollar, tax-exempt organizations or foreign corporations and persons who are not citizens or residents of the United States (except as described under the heading "--Taxation of Non-U.S. Holders of Notes"). In addition, this summary only addresses the federal income tax consequences of the Notes until the Remarketing Date. It does not give a detailed discussion of 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. As used herein, the term "U.S. Holder" means a holder of Notes who (for United States federal income tax purposes) (i) is a citizen or resident of the United States, (ii) is a corporation, partnership, or other entity created or organized in or under the laws of the United States or of any political subdivision thereof, (iii) is an estate the income of which is subject to United States federal income taxation regardless of its source or (iv) is a trust whose administration is subject to the primary supervision of a United States court and which has one or more United States persons who have the authority to control all substantial decisions of the trust. The term "Non-U.S. Holder" means a holder of Notes who is not a U.S. Holder. The information in this section is based on the Internal Revenue Code of 1986, as amended (the "Code"), current, temporary and proposed Treasury Regulations thereunder, the legislative history of the Code, current administrative interpretations and practices of the IRS and court decisions, all as of the date hereof. No assurance can be given that future legislation, Treasury Regulations, administrative interpretations and court decisions will not significantly change current law or adversely affect existing interpretations of current law. Any such change could apply retroactively to transactions preceding the date of the change. Thus, no assurance can be provided that the statements set forth herein (which do not bind the IRS or the courts) will not be challenged by the IRS or will be sustained by a court if so challenged. EACH PROSPECTIVE PURCHASER IS URGED TO CONSULT WITH ITS OWN TAX ADVISOR REGARDING THE SPECIFIC TAX CONSEQUENCES TO IT OF THE ACQUISITION, OWNERSHIP AND DISPOSITION OF NOTES IN LIGHT OF ITS SPECIFIC TAX AND INVESTMENT SITUATIONS AND THE SPECIFIC FEDERAL, STATE, LOCAL AND FOREIGN TAX LAWS APPLICABLE TO IT. TAXATION OF U.S. HOLDERS OF NOTES Interest on Notes. The federal income tax treatment of debt obligations such as the Notes is not certain. Because the Notes are subject to mandatory tender on the Remarketing Date, the Operating Partnership intends to treat the Notes as maturing on the Remarketing Date for federal income tax purposes. By purchasing the Notes, the U.S. Holder agrees to follow such treatment for federal income tax purposes. There can be no assurance that the Internal Revenue Service ("IRS") will agree with the Operating Partnership's treatment of the Notes and it is possible that the IRS could assert another treatment. For instance, it is possible that the IRS could seek to treat the Notes as maturing on the Stated Maturity Date. See "--Possible Characterization as Contingent Interest" below. In accordance with such treatment, interest on the Notes will constitute "qualified stated interest" and generally will 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). Under the foregoing, since the Notes are being issued to the Holder at par value, the Notes will not be treated as having original issue discount. Sale, Exchange or Retirement of Notes. Under the foregoing treatment, upon the sale, exchange or retirement of a Note, a U.S. Holder generally will recognize taxable gain or loss equal to the difference between the amount realized on the sale, exchange or retirement (other than amounts representing accrued and unpaid interest) and such U.S. Holder's adjusted tax basis in the Note. A U.S. Holder's adjusted tax basis in a Note generally will equal such U.S. Holder's initial investment in the Note (increased by accrued market discount, if any, if the U.S. Holder has included such market discount in income) and decreased by S-18 19 the amount of any payments, other than qualified stated interest payments, received and amortizable bond premium taken with respect to such Note. Such gain or loss will be capital if the Note is held as a capital asset. In the case of a U.S. Holder who is an individual or an estate or trust, such gain or loss will be long-term capital gain or loss, subject to a 28% tax rate, if the Notes have been held for more than one year but not more than 18 months, and long-term capital gain or loss, subject to a 20% tax rate, if the Notes have been held for more than 18 months. In the case of a U.S. Holder that is a corporation, such gain or loss will be long-term capital gain or loss if the Notes have been held for more than one year. Possible Characterization as Contingent Interest. It is possible that the IRS might seek to treat the Notes as maturing on the Stated Maturity Date (instead of on the Remarketing Date, as discussed under "--Interest on Notes" above) for federal income tax purposes. Pursuant to such treatment, since the Interest Rate to Maturity will not be determined until the Determination Date, the Notes would be treated as having contingent interest under the Code. In such event, under Treasury Regulations governing debt instruments that provide for contingent payments (the "Contingent Payment Regulations"), the Operating Partnership would be required to construct a projected payment schedule for the Notes, based upon the Operating Partnership's current borrowing costs for comparable debt instruments of the Operating Partnership, from which an estimated yield on the Notes would be calculated. A U.S. Holder would be required to include in income original issue discount in an amount equal to the sum of the daily portions of original issue discount on the Notes that would be deemed to accrue at this estimated yield for each day during the U.S. Holder's taxable year on which the U.S. Holder holds the Notes. The amount of original issue discount that would be deemed to accrue in any accrual period would equal the product of this estimated yield (properly adjusted for the length of the accrual period) and the Notes' adjusted issue price (as defined below) at the beginning of the accrual period. The daily portions of original issue discount would be determined by allocating to each day in the accrual period the ratable portion of the original issue discount that would be deemed to accrue during the accrual period. In general, for these purposes, a Note's adjusted issue price would equal the Note's issue price increased by the original issue discount previously accrued on the Note, and reduced by all payments made on the Note. As a result of the application of the Contingent Payment Regulations, it is possible that a U.S. Holder would be required to include original issue discount in income in excess of actual cash payments received for certain taxable years. Under the Contingent Payment Regulations, upon the sale or exchange of a Note (including a sale pursuant to the mandatory tender on the Remarketing Date), a U.S. Holder would be required to recognize taxable income or loss in an amount equal to the difference, if any, between the amount realized by the U.S. Holder upon such sale or exchange and the U.S. Holder's adjusted tax basis in the Note as of the date of disposition. A U.S. Holder's adjusted tax basis in a Note generally would equal such U.S. Holder's initial investment in the Note increased by any original issue discount previously included in income with respect to the Note by the U.S. Holder, and decreased by any payments received by the U.S. Holder. Any such taxable income generally would be treated as ordinary income. Any such taxable loss generally would be treated (i) first as an offset to any interest otherwise includible in income by the U.S. Holder with respect to the Notes for the taxable year in which the sale or exchange occurs to the extent of the amount of such includible interest and (ii) then as an ordinary loss to the extent of the U.S. Holder's total interest inclusions on the Notes in previous taxable years. Any remaining loss in excess of the amounts described in (i) and (ii) above generally would be treated as short-term, mid-term, or long term-capital loss (depending upon the U.S. Holder's holding period for the Notes). All amounts includible in income by a U.S. Holder as ordinary interest pursuant to the Contingent Payment Treasury Regulations would be treated as original issue discount. TAXATION OF NON-U.S. HOLDERS OF NOTES A Non-U.S. Holder will not be subject to federal income taxes on payments of principal, premium (if any) or interest on 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 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 Notes 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 S-19 20 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 of a Note 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 in the preceding paragraph (or by reason of the delivery of 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 dispositions 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 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 be made normally 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 United States Federal income tax provided the required information is furnished to the IRS. The United States Treasury has recently finalized regulations regarding the withholding and information reporting rules discussed above. In general, these regulations do not alter the substantive withholding and information reporting requirements but unify certification procedures and forms and clarify and modify reliance standards. These regulations generally are effective for payments made after December 31, 1999, subject to certain transition rules. Valid withholding certificates that are held on December 31, 1999, will remain valid until the earlier of December 31, 2000 or the date of expiration of the certificate under rules currently in effect (unless otherwise invalidated due to changes in the circumstances of the person whose name is on such certificate). A Non-U.S. Holder should consult its own advisor regarding the effect of the new Treasury Regulations. S-20 21 ERISA CONSIDERATIONS The Employee Retirement Income Security Act of 1974, as amended ("ERISA"), and the Code impose certain restrictions on (a) employee benefit plans (as defined in Section 3(3) of ERISA), (b) plans described in Section 4975 (e) (1) of the Code, including individual retirement accounts or Keogh plans, (c) any entities whose underlying assets include plan assets by reason of a plan's investment in such entities (each a "Plan") and (d) persons who have certain specified relationships to such Plans ("Parties-in-Interest" under ERISA and "Disqualified Persons" under the Code). ERISA also imposes certain duties on persons who are fiduciaries of Plans subject to ERISA and prohibits certain transactions between a Plan and Parties-in-Interest or Disqualified Persons with respect to such Plans. The Operating Partnership and the Remarketing Dealer, because of their activities or the activities of their respective affiliates, may be considered to be Parties-in-Interest or Disqualified Persons with respect to certain Plans. If the Notes are acquired by a Plan with respect to which the Operating Partnership or the Remarketing Dealer is, or subsequently becomes, a Party-in-Interest or Disqualified Person, the purchase, holding or sale of Notes to the Remarketing Dealer could be deemed to be a direct or indirect violation of the Prohibited Transaction rules of ERISA and the Code unless such transaction were subject to one or more statutory or administrative exemptions such as Prohibited Transaction Class Exemption ("PTCE") 75-1, which exempts certain transactions involving employee benefit plans and certain broker-dealers, reporting dealers and banks; PTCE 90-1, which exempts certain transactions between insurance company pooled separate accounts and Parties-in-Interest or Disqualified Persons; PTCE 91-38, which exempts certain transactions between bank collective investment funds and Parties-in-Interest or Disqualified Persons; PTCE 84-14, which exempts certain transactions effected on behalf of a Plan by a "qualified professional asset manager;" PTCE 95-60, which exempts certain transactions between insurance company general accounts and Parties-in-Interest or Disqualified Persons; or PTCE 96-23, which exempts certain transactions effected on behalf of a Plan by an "in-house asset manager." Even if the conditions specified in one or more of these exemptions are met, the scope of relief provided by these exemptions will not necessarily cover all acts in relation to an acquisition or sale of Notes that might be construed as prohibited transactions. Accordingly, prior to making an investment in the Notes, a Plan should determine whether the Operating Partnership or the Remarketing Dealer is a Party-in-Interest or Disqualified Person with respect to such Plan and, if so, whether such transaction is subject to one or more statutory or administrative exemptions, including those described above. Prior to making an investment in the Notes, Plans should consult with their legal advisers concerning the impact of ERISA and the Code and the potential consequences of such investment with respect to their specific circumstances. Moreover, each Plan fiduciary should take into account, among other considerations, whether the fiduciary has the authority to make the investment on behalf of the Plan; whether the investment constitutes a direct or indirect transaction with a Party-in-Interest or a Disqualified Person; and whether under the general fiduciary standards of investment procedure and diversification an investment in the Notes is appropriate for the Plan, taking into account, among other things, the overall investment policy of the Plan and the composition of the Plan's investment portfolio. S-21 22 UNDERWRITING Subject to the terms and conditions set forth in the Terms Agreement incorporating by reference the related Purchase Agreement (collectively, the "Purchase Agreement"), the Operating Partnership has agreed to sell to each of the Underwriters named below, and each of the Underwriters named below has severally agreed to purchase from the Operating Partnership, the respective principal amount of Notes set forth opposite its name below. PRINCIPAL AMOUNT UNDERWRITERS OF NOTES ----------- ---------------- Merrill Lynch, Pierce, Fenner Incorporated............................. $210,000,000 NationsBanc Montgomery Securities LLC ................ 45,000,000 Salomon Brothers Inc ................................. 45,000,000 ------------ TOTAL.................................... $300,000,000 ============ In the Purchase Agreement, the several Underwriters have agreed, subject to the terms and conditions set forth therein, to purchase all of the Notes offered hereby if any Notes are purchased. 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 relating to prevailing market 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 Operating Partnership has agreed to indemnify the Underwriters against certain liabilities, including civil liabilities under the Securities Act of 1933, as amended, or to contribute to payments the Underwriters may be required to make in respect thereof. 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 the Underwriters intend to make a market in the Notes as permitted by applicable laws and regulations, but the Underwriters 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. The Underwriters are permitted to engage in certain transactions that maintain or otherwise affect the price of the Notes. Such transactions may include over-allotment transactions and purchases to cover short positions created by the Underwriters in connection with the Offering. If the Underwriters create a short position in the Notes in connection with the Offering, i.e., if they sell Notes in an aggregate principal amount exceeding that 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, purchases of a security 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 makes any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the Notes. In addition, neither the Operating Partnership nor the Underwriters makes any representation that the Underwriters will engage in such transactions or that such transactions, once commenced, will not be discontinued without notice. The Underwriters from time to time provide 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.

Requests should be directed to ERP Operating Limited Partnership, c/o Equity Residential Properties Trust, Two North Riverside Plaza, Suite 400, Chicago, Illinois 60606, Attention: Cynthia McHugh (telephone number: (312) 474-1300). 3 26 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 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 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 C Preferred Shares"), the Company's 8.60% Series D Cumulative Redeemable Preferred Shares of Beneficial Interest, $.01 par value per share (the "Series D Preferred Shares"), the Company's Series E Cumulative Convertible Preferred Shares of Beneficial Interest, $.01 par value per share (the "Series E Preferred Shares"), the Company's 9.65% Series F Preferred Shares of Beneficial Interest, $.01 par value per share (the "Series F Preferred Shares"), and the Company's 7 1/4% Series G Convertible Cumulative Preferred Shares of Beneficial Interest, $.01 par value per share (the "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 4 27 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; 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. 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 OF 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. 5 28 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. For the Years Ended December 31, _____________________________________ 1997 1996 1995 1994 1993 1992 ----- ---- ---- ---- ---- ---- 1.64 1.59 1.54 2.18 1.25 .91 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. 6 29 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 7 30 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) 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 8 31 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 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). 9 32 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 10 33 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 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 1 5(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 1 5(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 1 5(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). 11 34 ADDITIONAL COVENANTS AND/OR MODIFICATIONS TO THE COVENANTS DESCRIBED ABOVE In addition to the covenants described in the section entitled "Certain Covenants - Limitations on Incurrence of Debt" above, the Operating Partnership is required to maintain Total Unencumbered Assets of not less than 150% of the aggregate outstanding principal amount of the Unsecured Debt of the Operating Partnership.

For the 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.

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 13 36 as obligor 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 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. 14 37 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 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 15 38 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 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 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 16 39 longer be applicable to such Debt Securities), the amount of Government Obligations on deposit with the Trustee will be sufficient 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 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 17 40 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 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. 18 41 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. 19 42 EXPERTS The consolidated financial statements of the Operating Partnership appearing in the Operating Partnership's 1997 Annual Report (Form 10-K) for the years ended December 31, 1997 and 1996; the consolidated financial statements of Evans Withycombe Residential, L.P. appearing in the Operating Partnership's Current Report on Form 8-K, dated September 10,1997; the consolidated financial statements of Wellsford and its subsidiaries included in the Operating Partnership's Current Report on Form 8-K, dated May 30, 1997; and the Statements of Revenue and Certain Expenses of certain properties either acquired or expected to be acquired, appearing in the Operating Partnership's Current Reports on Forms 8-K or 8-K/A dated May 20, 1997, August 15, 1997, September 17, 1997 and October 9, 1997; have all been audited by Ernst & Young LLP, independent auditors, as set forth in their reports thereon included or incorporated by reference therein and are incorporated herein by reference in reliance upon such reports given upon the authority of such firm as experts in accounting and auditing.
