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 THE OPERATING PARTNERSHIP GENERAL The Debt Securities 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. The Company 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"). The Company 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. The Company's senior executives average over 23 years of experience in the multifamily property business. All of the Company's interests in its multifamily properties (the "Properties") are held 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 four 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, $0.01 par value per share ("Common Shares"), on a one-for-one basis or, at the Company's option, cash; (ii) 9 3/8% Cumulative Redeemable Preference Units ("9 3/8% Preference Units"); (iii) 9 1/8% Cumulative Redeemable Preference Units ("9 1/8% Series B Preference Units"); and (iv) 9 1/8% Series C Cumulative Redeemable Preference Units ("9 1/8% Series C Preference Units"). The 9 3/8% Preference Units, the 9 1/8% Series B Preference Units, and the 9 1/8% Series C 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"), and the Company's 9 1/8% Series C Cumulative Redeemable Preferred Shares of Beneficial Interest, $.01 per value per share (the "Series C Preferred Shares"), respectively. The Company controls the Operating Partnership as the sole general partner and, as of September 25, 1996, owned approximately 84% of all of the Operating Partnership's outstanding partnership interests, excluding the 9 3/8% Preference Units, the 9 1/8% Series B Preference Units, and the 9 1/8% Series C 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 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. THE OPERATING SUBSIDIARIES Essentially all operations of the Company are conducted directly or indirectly by the Operating Partnership and those entities owned or controlled by the Operating Partnership (collectively, the "Subsidiaries"), so that, among other things, the Company is able to comply with certain technical and complex requirements under the Federal tax law relating to the assets and income that a REIT may hold or earn. In this regard, the Company has established: (i) the Operating Partnership which benefited those entities that contributed certain of the 69 Properties acquired by the Operating Partnership in connection with the IPO in exchange for OP Units by allowing them to partially defer certain tax consequences and which will allow the Operating Partnership to acquire additional multifamily properties in transactions that may defer some or all of the sellers' tax consequences, (ii) Equity Residential Properties Management 4 Corp., Equity Residential Properties Management Corp. II, and Equity Residential Properties Management Corp. III (collectively, the "Management Corps") and Equity Residential Properties Management Limited Partnership and Equity Residential Properties Management Limited Partnership II (collectively, the "Management Partnerships") which 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, 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. RISK FACTORS Prospective investors should carefully consider, among other factors, the matters described below prior to making an investment decision regarding the Debt Securities offered hereby. ADVERSE CONSEQUENCES OF DEBT FINANCING AND PREFERRED SHARES General Risks. As of June 30, 1996, the Properties were subject to approximately $667.8 million of mortgage indebtedness and the Operating Partnership's total debt equaled approximately $1.04 billion, $151.5 million of which was floating rate debt. Subsequent to June 30, 1996, the Operating Partnership issued $150 million aggregate principal amount of 7.57% Notes due August 15, 2026 pursuant to a public debt offering in August 1996 (the "Debt Offering"). In addition, in June 1995, the Company issued 6,120,000 Series A Preferred Shares pursuant to a preferred share offering; in November 1995, the Company issued 5,000,000 depositary shares each representing a 1/10 fractional interest in a Series B Preferred Share pursuant to a depositary share offering; and in September 1996, the Company issued 4,600,000 depositary shares each representing a 1/10 fractional interest in a Series C Preferred Share pursuant to a depositary share offering (collectively, the "Preferred Share Offerings"). The Operating Partnership used the proceeds from the Debt Offering and the Preferred Share Offerings to repay indebtedness and to acquire additional Properties. The Operating Partnership is subject to the risks normally associated with debt or preferred equity financing, including the risk that the Operating Partnership's cash flow will be insufficient to meet required payments of principal and interest, the risk that existing indebtedness may not be refinanced or that the terms of such refinancing will not be as favorable as the terms of current indebtedness and the risk that necessary capital expenditures for such purposes as renovations and other improvements may not be financed on favorable terms or at all. If the Operating Partnership were unable to refinance its indebtedness on acceptable terms, or at all, the Operating Partnership might be forced to dispose of one or more of the Properties on disadvantageous terms, which might result in losses to the Operating Partnership and and might adversely affect the cash available for distributions to shareholders. If interest rates or other factors at the time of the refinancing result in higher interest rates upon refinancing, the Operating Partnership's interest expense would increase, which would affect the Operating Partnership's ability to make distributions to its shareholders. Furthermore, if a Property is mortgaged to secure payment of indebtedness and the Operating Partnership is unable to meet mortgage payments, the mortgagee could foreclose upon the Property, appoint a receiver and receive an assignment of rents and leases or pursue other remedies, all with a consequent loss of income and asset value to the Operating Partnership. Foreclosures could also create taxable income without accompanying cash proceeds, thereby hindering the Company's ability to meet the REIT distribution requirements of the Internal Revenue Code of 1986, as amended (the "Code"). Restrictions on the Company's Activities. A substantial portion of the Operating Partnership's debt has been issued pursuant to two different indentures (the "Indentures") which restrict the amount of indebtedness (including acquisition financing) the Operating Partnership may incur. Accordingly, if the Company or the Operating Partnership is unable to raise additional equity or borrow money, respectively, because of the debt restrictions in the indentures, the Operating Partnership's ability to acquire additional properties may be limited. 5 Bond Compliance Requirements. The Operating Partnership owns several Properties that are subject to restrictive covenants or deed restrictions relating to current or previous tax-exempt bond financing and owns the bonds collateralized by several additional Properties. The Operating Partnership has retained an independent outside consultant to monitor compliance with the restrictive covenants and deed restrictions that affect these Properties. The bond compliance requirements may have the effect of limiting the Operating Partnership's income from these Properties if the Operating Partnership is required to lower its rental rates to attract low or moderate income tenants, or eligible/qualified tenants. POTENTIAL ENVIRONMENTAL LIABILITY AFFECTING THE COMPANY Under various Federal, state and local environmental laws, ordinances and regulations, an owner of real estate may be liable for the costs of removal or remediation of certain hazardous or toxic substances on such property. These laws often impose environmental liability without regard to whether the owner knew of, or was responsible for, the presence of such hazardous or toxic substances. The presence of such substances, or the failure properly to remediate such substances, may adversely affect the owner's ability to sell or rent the property or to borrow using the property as collateral. Persons who arrange for the disposal or treatment of hazardous or toxic substances may also be liable for the costs of removal or remediation of such substances at a disposal or treatment facility, whether or not such facility is owned or operated by such person. Certain laws impose liability for release of asbestos-containing materials ("ACMs") into the air and third parties may seek recovery from owners or operators of real properties for personal injury associated with ACMs. In connection with the ownership (direct or indirect), operation, management and development of real properties, the Operating Partnership or the Subsidiaries, as the case may be, may be considered an owner or operator of such properties or as having arranged for the disposal or treatment of hazardous or toxic substances and, therefore, potentially liable for removal or remediation costs, as well as certain other related costs, including governmental fines and injuries to persons and property. All of the Properties have been the subject of a Phase I or similar environmental assessment (which involves general inspections without soil sampling or ground water analysis and generally without radon testing) completed by qualified independent environmental consultant companies. All of the environmental assessments were conducted within the last five years and were obtained prior to the acquisition by the Operating Partnership of each of the Properties. These environmental assessments have not revealed, nor is the Operating Partnership aware of, any environmental liability that the Operating Partnerships's management believes would have a material adverse effect on the Operating Partnership's business, results of operations, financial condition or liquidity. No assurance can be given that existing environmental assessments with respect to any of the Properties reveal all environmental liabilities, that any prior owner of a Property did not create any material environmental condition not known to the Operating Partnership, or that a material environmental condition does not otherwise exist as to any one or more Properties. REAL ESTATE INVESTMENT CONSIDERATIONS General. Income from real property investments and the Operating Partnership's resulting ability to make expected interest payments on Debt Securities may be adversely affected by the general economic climate, local conditions such as oversupply of apartment units or a reduction in demand for apartment units in the area, the attractiveness of the Properties to tenants, zoning or other regulatory restrictions, the ability of the Operating Partnership to provide adequate maintenance and insurance, and increased operating costs (including insurance premiums and real estate taxes). The Operating Partnership's income would also be adversely affected if tenants were unable to pay rent or the Company were unable to rent apartment units on favorable terms. If the Operating Partnership were unable to promptly relet or renew the leases for a significant number of apartment units, or if the rental rates upon such renewal or reletting were significantly lower than expected rates, then the Operating Partnership's income and ability to make expected distributions to shareholders may be adversely affected. In addition, certain expenditures 6 associated with each equity investment (such as real estate taxes and maintenance costs) generally are not reduced when circumstances cause a reduction in income from the investment. Furthermore, real estate investments are relatively illiquid and, therefore, will tend to limit the ability of the Operating Partnership to vary its portfolio promptly in response to changes in economic or other conditions. Changes in Laws. Increases in real estate taxes and income, service or other taxes generally are not passed through to tenants under existing leases and may adversely affect the Operating Partnership's income and its ability to make interest payments on Debt Securities. Similarly, changes in laws increasing the potential liability for environmental conditions existing on properties or increasing the restrictions on discharges or other conditions may result in significant unanticipated expenditures, which would adversely affect the Operating Partnership's income and its ability to make interest payments on Debt Securities. DEPENDENCE ON KEY PERSONNEL The Operating Partnership is dependent on the efforts of the Company's executive officers. While the Operating Partnership believes that it could find replacements for these key personnel, the loss of their services could have a temporary adverse effect on the operations of the Operating Partnership. None of these officers has entered into employment agreements with the Company. DISTRIBUTION REQUIREMENTS POTENTIALLY INCREASING INDEBTEDNESS OF THE COMPANY The Company may be required from time to time, under certain circumstances, to accrue as income for tax purposes interest and rent earned but not yet received. In such event, or upon the repayment by the Operating Partnership or its Subsidiaries of principal on debt, the Company could have taxable income without sufficient cash to enable the Company to meet the distribution requirements of a REIT. Accordingly, the Operating Partnership could be required to borrow funds or liquidate investments on adverse terms in order to allow the Company to meet such distribution requirements. 7 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 Six For the Six Months Months For the Years Ended December 31, Ended June 30, Ended June 30, ---------------------------------------- 1996 1995 1995 1994 1993 1992 1991 - - --------------- -------------- ---- ---- ---- ---- ---- 1.57 1.61 1.54 2.18 1.25 .91 .82 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. 8 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; 9 (4) the date or dates, or the method for determining such date or dates, on which the principal of such Debt Securities will be payable; (5) the rate or rates (which may be fixed or variable), or the method by which such rate or rates shall be determined, at which such Debt Securities will bear interest, if any; (6) the date or dates, or the method for determining such date or dates, from which any such interest will accrue, the Interest Payment Dates on which any such interest will be payable, the Regular Record Dates for such Interest Payment Dates, or the method by which such dates shall be determined, the Person to whom such interest shall be payable, and the basis upon which interest shall be calculated if other than that of a 360- day year of twelve 30-day months; (7) the place or places where 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, such Debt Securities may be surrendered for conversion or registration of transfer or exchange and 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 U.S. 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, 10 whether the Operating Partnership will have the option to redeem such Debt Securities in lieu of making such payment; (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 U.S. federal income tax, accounting and other considerations applicable to Original Issue Discount Securities will be described in the applicable Prospectus Supplement. Except as set forth below under "Certain Covenants - Limitations on Incurrence of Debt," the Indenture does not contain any other provisions that would limit the ability of the Operating Partnership to incur indebtedness or that would afford Holders of Debt Securities protection in the event of a highly leveraged or similar transaction involving the Operating Partnership or in the event of a change of control. However, restrictions on ownership and transfers of the Company's Common Shares and preferred shares of beneficial interest are designed to preserve its status as a REIT and, therefore, may act to prevent or hinder a change of control. Reference is made to the applicable Prospectus Supplement for information with respect to any deletions from, modifications of or additions to the Events of Default or covenants of the Operating Partnership that are described below, including any addition of a covenant or other provision providing event risk or similar protection. DENOMINATIONS, INTEREST, REGISTRATION AND TRANSFER Unless otherwise described in the applicable Prospectus Supplement, the Registered Securities of any series will be issuable in denominations of $1,000 and integral multiples thereof (Section 302). Unless otherwise specified in the applicable Prospectus Supplement, the principal of (and premium, if any) and interest on any series of Debt Securities will be payable at the corporate trust office of the Trustee, initially located at 14 Wall Street, Eighth Floor, New York, New York; provided that, at the option of the Operating Partnership, payment of interest may be made by check mailed to the address of the Person entitled thereto as it appears in the Security Register or by wire transfer of funds to such Person at an account maintained within the United States (Sections 301, 305, 306, 307 and 1002). Any interest not punctually paid or duly provided for on any Interest Payment Date with respect to a Debt Security ("Defaulted Interest") will forthwith cease to be payable to the Holder on the applicable Regular Record Date and may either be paid to the person in whose name such Debt Security is registered at the close of business on a special record date (the "Special Record Date") for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to the Holder of such Debt Security not less than 10 days prior to such Special Record Date, or may be paid at any time in any other lawful manner, all as more completely described in the Indenture. 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 11 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 as been surrendered for repayment at the option of the Holder, except the portion, if any, of such Debt Security not to be so repaid (Section 305). MERGER, CONSOLIDATION OR SALE The Operating Partnership may consolidate with, or sell, lease or convey all or substantially all of its assets to, or merge with or into any other entity, provided that (i) the Operating Partnership shall be the continuing entity, or the successor entity shall be an entity organized and existing under the laws of the United States or a state thereof and such successor entity shall expressly assume payment of the principal of and premium (if any) and any interest (including all Additional Amounts, if any, payable pursuant to Section 1012) on all of the Debt Securities and the due and punctual performance and observance of all of the covenants and conditions contained in the Indenture, (ii) immediately after giving effect to such transaction and treating any indebtedness which becomes an obligation of the Operating Partnership or any Subsidiary as a result thereof as having been incurred by the Operating Partnership, or such Subsidiary at the time of such transaction, no Event of Default under the Indenture, and no event which after notice or the lapse of time, or both, would become such an Event of Default, shall have occurred and be continuing; and (iii) an officer's certificate of the Company as general partner of the Operating Partnership and legal opinion covering such conditions shall be delivered to the Trustee (Sections 801 and 803). CERTAIN COVENANTS Limitations on Incurrence of Debt. The Operating Partnership will not, and will not permit any Subsidiary to incur any Debt (as defined below), other than intercompany Debt (representing Debt to which the only parties are the Company, the Operating Partnership and any of its Subsidiaries, (but only so long as such Debt is held solely by any of the Company, the Operating Partnership and any Subsidiary) that is subordinate in right of payment of the Debt Securities, if, immediately after giving effect to the incurrence of such additional Debt, the aggregate principal amount of all outstanding Debt of the Operating Partnership and its Subsidiaries on a consolidated basis determined in accordance with generally accepted accounting principles is greater than 60% of the sum of (i) the Operating Partnership's Total Assets (as defined below) as of the end of the calendar quarter covered in the Operating Partnership's Annual Report on Form 10-K or Quarterly Report on Form 10-Q, as the case may be, most recently filed with the Commission (or, if such filing is not permitted under the Exchange Act, with the Trustee) prior to the incurrence of such additional Debt and (ii) the increase in Total Assets from the end of such quarter including, without limitation, any increase in Total Assets caused by the incurrence of such additional Debt (such increase together with the Company's Total Assets shall be referred to as the "Adjusted Total Assets") (Section 1004). In addition to the foregoing limitation on the incurrence of Debt, the Operating Partnership will not and will not permit any Subsidiary to incur any Debt if the ratio of Consolidated Income Available for Debt Service to the Maximum Annual Service Charge for the four consecutive fiscal quarters most recently ended prior to the date on which such additional Debt is to be incurred shall have been less than 1.5 to 1, on a pro forma basis after giving effect to the incurrence of such Debt and to the application of the proceeds therefrom, and calculated on the assumption that 12 (i) such Debt and any other Debt incurred by the Operating Partnership or its Subsidiaries since the first day of such four-quarter period and the application of the proceeds therefrom, including to refinance other Debt, had occurred at the beginning of such period, (ii) the repayment or retirement of any other Debt by the Operating Partnership or its Subsidiaries since the first day of such four-quarter period had been incurred, repaid or retired at the beginning of such period (except that, in making such computation, the amount of Debt under any revolving credit facility shall be computed based upon the average daily balance of such Debt during such period), (iii) the income earned on any increase in Adjusted Total Assets since the end of such four-quarter period had been earned, on an annualized basis, during such period; and (iv) in the case of any acquisition or disposition by the Operating Partnership or any Subsidiary of any asset or group of assets since the first day of such four-quarter period, including, without limitation, by merger, stock purchase or sale, or asset purchase or sale, such acquisition or disposition or any related repayment of Debt had occurred as of the first day of such period with the appropriate adjustments with respect to such acquisition or disposition being included in such pro forma calculation (Section 1004). In addition to the foregoing limitations on the incurrence of Debt, the Operating Partnership will not, and will not permit any Subsidiary to incur any Debt secured by any mortgage, lien, charge, pledge, encumbrance or security interest of any kind upon any of the property of the Operating Partnership or any Subsidiary ("Secured Debt"), whether owned at the date of the Indenture or thereafter acquired, if, immediately after giving effect to the incurrence of such additional Secured Debt, the aggregate principal amount of all outstanding Secured Debt of the Operating Partnership and its Subsidiaries on a consolidated basis is greater than 40% of the Adjusted Total Assets (Section 1004). Notwithstanding the limitation set forth in the preceding paragraph, the Indenture provides that the Operating Partnership and its Subsidiaries may incur Secured Debt, provided that such Secured Debt is incurred under the Acquisition Lines of Credit, and provided further that after the increase of such Secured Debt under the Acquisition Lines of Credit, the aggregate principal amount of all outstanding Secured Debt, including debt under the Acquisition Lines of Credit of the Operating Partnership or any Subsidiary does not exceed 45% of the Adjusted Total Assets; provided, however, that the aggregate principal amount of all outstanding Secured Debt of the Operating Partnership and its Subsidiaries on a consolidated basis may exceed 40% of the Adjusted Total Assets for not more than 270 days of any consecutive 360 day period. For purposes of the foregoing provisions regarding the limitation on the incurrence of Debt, Debt shall be deemed to be "incurred" by the Operating Partnership and its Subsidiaries on a consolidated basis whenever the Operating Partnership and its Subsidiaries on a consolidated basis shall create, assume, guarantee or otherwise become liable in respect thereof. Restrictions on Distributions. The Operating Partnership will not make any distribution, by reduction of capital or otherwise (other than distributions payable in securities evidencing interests in the Operating Partnership's capital for the purpose of acquiring interests in real property or otherwise) if, immediately after such distribution the aggregate of all such distributions made since March 31, 1993 shall exceed Funds from Operations of the Operating Partnership and its Subsidiaries from March 31, 1993 until the end of the calendar quarter covered in the Operating Partnership's Annual Report on Form 10-K or Quarterly Report on Form 10-Q, as the 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). 13 Existence. Except as permitted under "Merger, Consolidation or Sale," the Operating Partnership will do or cause to be done all things necessary to preserve and keep in full force and effect its existence, rights and franchises; provided, however, that the Operating Partnership shall not be required to preserve any right or franchise if it determines that the preservation thereof is no longer desirable in the conduct of the business of the Operating Partnership, and that the loss thereof is not disadvantageous in any material respect to the Holders of the Debt Securities. Maintenance of Properties. The Operating Partnership will cause all of its properties used or useful in the conduct of its business or the business of any Subsidiary to be maintained and kept in good condition, repair and working order and supplied with all necessary equipment and will cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as in the judgment of the Operating Partnership may be necessary so that the business carried on in connection therewith may be properly and advantageously conducted at all times; provided, however, that the Operating Partnership shall not be prevented from selling or otherwise disposing for value its properties in the ordinary course of business (Section 1007). Insurance. The Operating Partnership will and will cause each of its Subsidiaries to, keep all of its insurable properties insured against loss or damage at least equal to their then fully insurable value with financially sound and reputable insurance companies (Section 1008). Payment of Taxes and Other Claims. The Operating Partnership will pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (i) all taxes, assessments and governmental charges levied or imposed upon it or any Subsidiary or upon the income, profits or property of the Operating Partnership or any Subsidiary, and (ii) all lawful claims for labor, materials and supplies which, if unpaid, might by law become a lien upon the property of the Operating Partnership or any Subsidiary; provided, however, that the Operating Partnership shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith by appropriate proceedings (Section 1009). Provision of Financial Information. The Holders of the Debt Securities will be provided with copies of the annual reports and quarterly reports of the Operating Partnership. Whether or not the Operating Partnership is subject to Section 13 or 15(d) of the Exchange Act, the Operating Partnership will, to the extent permitted under the Exchange Act, file with the Commission the annual reports, quarterly reports and other documents which the Operating Partnership would have been required to file with the Commission pursuant to such Section 13 or 15(d) (the "Financial Statements") if the Operating Partnership were so subject, such documents to be filed with the Commission on or prior to the respective dates (the "Required Filing Dates") by which the Operating Partnership would have been required so to file such documents if the Operating Partnership were so subject. The Operating Partnership will also in any event (x) within 15 days of each Required Filing Date (i) transmit by mail to all Holders of Debt Securities, as their names and addresses appear in the Security Register, without cost to such Holders, copies of the annual reports and quarterly reports which the Operating Partnership would have been required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act if the Operating Partnership were subject to such Sections and (ii) file with the Trustee copies of the annual reports, quarterly reports and other documents which the Operating Partnership would have been required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act if the Operating Partnership were subject to such Sections and (y) if filing such documents by the Operating Partnership with the Commission is not permitted under the Exchange Act, promptly upon written request and payment of the reasonable cost of duplication and delivery, supply copies of such documents to any prospective Holder (Section 1010).

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

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 17 60 days, to act after it has received a written request to institute proceedings in respect of an Event of Default from the Holders of not less than 25% in principal amount of the Outstanding Debt Securities of such series, as well as an offer of indemnity reasonably satisfactory to it (Section 507). This provision will not prevent, however, any Holder of Debt Securities from instituting suit for the enforcement of payment of the principal of and premium (if any) and interest on such Debt Securities at the respective due dates thereof (Section 508). Subject to provisions in the Indenture relating to its duties in case of default, the Trustee is under no obligation to exercise any of its rights or powers under the Indenture at the request or direction of any Holders of any series of Debt Securities then Outstanding under the Indenture, unless such Holders shall have offered to the Trustee reasonable security or indemnity (Section 602). The Holders of not less than a majority in principal amount of the Outstanding Debt Securities of any series (or of all Debt Securities then Outstanding under the Indenture, as the case may be) shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or of exercising any trust or power conferred upon the Trustee. However, the Trustee may refuse to follow any direction which is in conflict with any law or the Indenture, which may involve the Trustee in personal liability or which may be unduly prejudicial to the Holders of Debt Securities of such series not joining therein (Section 512). Within 120 days after the close of each fiscal year, the Operating Partnership must deliver to the Trustee a certificate, signed by one of several specified officers of the Company as to such officer's knowledge of the Operating Partnership's compliance with all conditions and covenants under the Indenture, and, in the event of any noncompliance, specifying each such noncompliance and the nature and status thereof. MODIFICATION OF THE INDENTURE Modifications and amendments of the Indenture may be made only with the consent of the Holders of not less than a majority in principal amount of all Outstanding Debt Securities of each series issued under the Indenture which are affected by such modification or amendment; provided, however, that no such modification or amendment may, without the consent of the Holder of each such Debt Security affected thereby, (i) change the Stated Maturity of the principal of, or any installment of principal of and premium (if any) or interest on, any such Debt Security; (ii) reduce the principal amount of, or the rate or amount of interest on, or premium payable upon the redemption of any such Debt Security; (iii) change the Place of Payment, or the currency, for payment of principal of any Debt Security or any premium or interest on any such Debt Security; (iv) impair the right to institute suit for the enforcement of any payment on or with respect to any such Debt Security; (v) reduce the above- stated percentage of Outstanding Debt Securities of any series necessary to modify or amend the Indenture, to waive compliance with certain provisions thereof or certain defaults and consequences thereunder or to reduce the quorum or voting requirements set forth in the Indenture; or (vi) modify any of the foregoing provisions or any of the provisions relating to the waiver of certain past defaults or certain covenants, except to increase the required percentage to effect such action or to provide that certain other provisions may not be modified or waived without the consent of the Holder of such Debt Security or (vii) adversely modify or affect (in any manner adverse to the Holders) the terms and conditions of the obligations of the Operating Partnership in respect of the due and punctual payment of the principal of and premium (if any), or interest on the Debt Securities (Section 902). The Holders of not less than a majority in principal amount of Outstanding Debt Securities of each series effected thereby have the right to waive compliance by the Operating Partnership with certain covenants in the Indenture (Section 1013). Modifications and amendments of the Indenture may be permitted to be made by the Operating Partnership and the Trustee without the consent of any Holders of Debt Securities for any of the following purposes: (i) to evidence the succession of another Person to the Operating Partnership as obligor under the Indenture; (ii) to add to the covenants of the Operating Partnership for the benefit of the Holders of all or any series of Debt Securities or to surrender any right or power conferred upon the Operating Partnership in Indenture; (iii) to add Events of Default for 18 the benefit of the Holders of all or any series of Debt Securities; (iv) to change or eliminate any of the provisions of the Indenture, provided that any such change or elimination shall become effective only when there is no Debt Security Outstanding of any series created prior to the modification or amendment which is entitled to the benefit of such provision; (v) to secure the Debt Securities; (vi) to provide for the acceptance of appointment by a successor Trustee or facilitate the administration of the trusts under the Indenture by more than one Trustee; (vii) to cure any ambiguity, defect or inconsistency in the Indenture, provided that such action shall not adversely affect the interests of Holders of Debt Securities of any series issued under the Indenture in any material respect; or (viii) to supplement any of the provisions of the Indenture to the extent necessary to permit or facilitate defeasance and discharge of any series of such Debt Securities, provided that such action shall not adversely affect the interests of the Holders of the Debt Securities of any series in any material respect (Section 901). The Indenture provides that in determining whether the Holders of the requisite principal amount of Outstanding Debt Securities of a series have given any request, demand, authorization, direction, notice, consent or waiver thereunder or whether a quorum is present at a meeting of Holders of Debt Securities, Debt Securities owned by the Operating Partnership, or any other obligor upon the Debt Securities or any affiliate of the Operating Partnership, Company or of such other obligor shall be disregarded. The Indenture contains provisions for convening meetings of the Holders of Debt Securities of a series (Section 1501). A meeting may be called at any time by the Trustee, and also, upon request, by the Operating Partnership or by the Holders of at least 10% in principal amount of the Outstanding Debt Securities of such series, or in any such case, upon notice given as provided in the Indenture (Section 1502). Except for any consent that must be given by the Holder of each Debt Security affected by certain modifications and amendments of the Indenture, any resolution presented at a meeting or adjourned meeting duly reconvened at which a quorum is present may be adopted by the affirmative vote of the Holders of a majority in principal amount of the Outstanding Debt Securities of that series; provided, however, that, except as referred to above, any resolution with respect to any request, demand, authorization, direction, notice, consent, waiver or other action that may be made, given or taken by the Holders of a specified percentage, which is less than a majority, in principal amount of the Outstanding Debt Securities of a series may be adopted at a meeting or adjourned meeting duly reconvened at which a quorum is present by the affirmative vote of the Holders of such specified percentage in principal amount of the Outstanding Debt Securities of that series. Any resolution passed or decision taken at any meeting of Holders of Debt Securities of any series duly held in accordance with the Indenture will be binding on all Holders of Debt Securities of that series. The quorum at any meeting called to adopt a resolution, and at any reconvened meeting, will be Persons holding or presenting a majority in principal amount of the Outstanding Debt Securities of a series; provided, however, that if any action is to be taken at such meeting with respect to a consent or waiver which may be given by the Holders of not less than a 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). 19 DISCHARGE, DEFEASANCE AND COVENANT DEFEASANCE The Operating Partnership may discharge certain obligations to Holders of any series of Debt Securities that either have become due and payable or will become due and payable within one year (or scheduled for redemption within one year) by irrevocably depositing with the Trustee, in trust, funds in an amount sufficient to pay and discharge the entire indebtedness on such Debt Securities in respect of principal and premium (if any) and interest to the date of such deposit (if such Debt Securities have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be (Section 1401). The Indenture provides that, if the provisions of Article Fourteen 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 decease and be discharged from any and all obligations with respect to such Debt Securities (except for the obligations to register the transfer or exchange of such Debt Securities, to replace temporary or mutilated, destroyed, lost or stolen Debt Securities, to maintain an office or agency in respect of such Debt Securities and to hold moneys for payment in trust) ("defeasance") (Section 1402) or (ii) to be released from its obligations with respect to such Debt Securities under Sections 1004 to 1010, inclusive, of the Indenture (being the restrictions described under "Certain Covenants") and any omission to comply with such obligations shall not constitute a default or an Event of Default with respect to such Debt Securities ("covenant defeasance") (Section 1403), in either case upon the irrevocable deposit by the Operating Partnership with the Trustee, in trust, of an amount, in cash or Government Obligations (as defined below), or both, which through the scheduled payment of principal and interest in accordance with their terms will provide money in an amount sufficient without reinvestment to pay the principal of and premium (if any) and interest on such Debt Securities on the scheduled due dates therefor. Such a trust may only be established if, among other things, the Operating Partnership has delivered to the applicable Trustee an Opinion of Counsel (as specified in the Indenture) to the effect that the Holders of such Debt Securities will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such defeasance or covenant defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such defeasance or covenant defeasance had not occurred, and such Opinion of Counsel, in the case of defeasance, must refer to and be based upon a ruling of the Internal Revenue Service or a change in applicable United States federal income tax law occurring after the date of the Indenture (Section 1404). "Government Obligations" means securities which are (i) direct obligations of the United States of America, for the payment of which its full faith and credit is pledged or (ii) obligations of a Person controlled or supervised by and acting as an agency or instrumentality of the United States of America, the timely payment of which is unconditionally guaranteed as a full faith and credit obligation by the United States of America, which are not callable or redeemable at the option or the issuer thereof, and shall also include a depository receipt issued by a bank or trust company as custodian with respect to any such Government Obligation or specific payment of interest on or principal of any such Government Obligation held by such custodian for the account of the Holder of a depository receipt, provided that (except as required by law) such custodian is not authorized to make any deduction from the amount payable to the Holder of such depository receipt from any amount received by the custodian in respect of the Government Obligation or the specific payment of interest on or principal of the Government Obligation evidenced by such depository receipt. In the event the Operating Partnership effects covenant defeasance with respect to any Debt Securities, and such Debt Securities are declared due and payable because of the occurrence of any Event of Default other than the Event of Default described in clause (iii) under "Events of Default, Notice and Waiver" with respect to Sections 1004 to 1010, inclusive, of the Indenture (which Sections would no longer be applicable to such Debt Securities), the amount of Government Obligations on deposit with the Trustee will be sufficient to pay amounts due on such Debt Securities at the time of their Stated Maturity but may not be sufficient to pay amounts due on such Debt Securities at the time of the 20 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 21 require that certain purchasers of securities take physical delivery of such securities in definitive form. Such limits and such laws may impair the ability to own, transfer, or pledge beneficial interests in the Global Note. So long as DTC or its nominee is the registered owner of the Global Note, DTC or such nominee, as the case may be, will be considered the sole owner or holder of the Debt Securities represented by the Global Note for all purposes under the Indenture. Except as set forth below, owners of beneficial interests in the Global Note will not be entitled to have the Debt Securities represented by the Global Note registered in their names, will not receive or be entitled to receive physical delivery of the Debt Securities in definitive form, and will not be considered the owners or holders thereof under the Indenture. Accordingly, each person owning a beneficial interest in the Global Note must rely on the procedures of DTC and, if such person is not a participant, on the procedures of the participant through which such person owns its interest, to exercise any rights of a holder under the Indenture. The Operating 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. 22 SAME-DAY SETTLEMENT If 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. 23 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. 24 EXPERTS The Consolidated and Combined Financial Statements incorporated in this Prospectus by reference to the Operating Partnership's Annual Report on Form 10-K, as amended by Form 10-K/A, for the year ended December 31, 1995 have been so incorporated in reliance on the reports of Grant Thornton LLP, independent accountants, given on the authority of said firm as experts in auditing and accounting.
