(1) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by or pursuant to this Indenture to be made, given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by an agent duly appointed in writing. If, but only if, Securities of a series are issuable as Bearer Securities, any request, demand, authorization, direction, notice, consent, waiver or other action provided in or pursuant to this Indenture to be made, given or taken by Holders of Securities of such series may, alternatively, be embodied in and evidenced by the record of Holders of Securities of such series voting in favor thereof, either in person or by proxies duly appointed in writing, at any meeting of Holders of Securities of such series duly called and held in accordance with the provisions of Article Fifteen, or a combination of such instruments and any such record. Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments or record or both are delivered to the Trustee and, where it is hereby expressly required, to the Operating Partnership and the Guarantor. Such instrument or instruments and any such record (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments or so voting at any such meeting. Proof of execution of any such instrument or of a writing appointing any such agent, or of the holding by any Person of a Security, shall be sufficient for any purpose of this Indenture and (subject to Section 315 of the Trust Indenture Act) conclusive in favor of the Trustee, the Operating Partnership, the Guarantor and any agent of the Trustee, the Operating Partnership or the Guarantor, if made in the manner provided in this Section. The record of any meeting of Holders of Securities shall be proved in the manner provided in Section 1506.

Without limiting the generality of this Section 104, unless otherwise provided in or pursuant to this Indenture, a Holder, including a Depository that is a Holder of a global Security, may make, give or take, by a proxy or proxies, duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other Act provided in or pursuant to this Indenture or the Securities to be made, given or taken by Holders, and a Depository that is a Holder of a global Security may provide its proxy or proxies to the beneficial owners of interests in any such global Security through such Depository’s standing instructions and customary practices.

(2) The fact and date of the execution by any Person of any such instrument or writing may be proved in any reasonable manner which the Trustee deems sufficient and in accordance with such reasonable rules as the Trustee may determine; and the Trustee

may in any instance require further proof with respect to any of the matters referred to in this Section.

(3) The ownership, principal amount and serial numbers of Registered Securities held by any Person, and the date of the commencement and the date of the termination of holding the same, shall be proved by the Security Register.

(4) The ownership, principal amount and serial numbers of Bearer Securities held by any Person, and the date of the commencement and the date of the termination of holding the same, may be proved by the production of such Bearer Securities or by a certificate executed, as depositary, by any trust company, bank, banker or other depositary reasonably acceptable to the Operating Partnership, wherever situated, if such certificate shall be deemed by the Operating Partnership and the Trustee to be satisfactory, showing that at the date therein mentioned such Person had on deposit with such depositary, or exhibited to it, the Bearer Securities therein described; or such facts may be proved by the certificate or affidavit of the Person holding such Bearer Securities, if such certificate or affidavit is deemed by the Operating Partnership and the Trustee to be satisfactory. The Trustee and the Operating Partnership may assume that such ownership of any Bearer Security continues until (1) another certificate or affidavit bearing a later date issued in respect of the same Bearer Security is produced, or (2) such Bearer Security is produced to the Trustee by some other Person, or (3) such Bearer Security is surrendered in exchange for a Registered Security, or (4) such Bearer Security is no longer Outstanding. The ownership, principal amount and serial numbers of Bearer Securities held by the Person so executing such instrument or writing and the date of the commencement and the date of the termination of holding the same may also be proved in any other manner which the Operating Partnership and the Trustee deem sufficient.

(5) If the Operating Partnership or the Guarantor shall solicit from the Holders of any Registered Securities any request, demand, authorization, direction, notice, consent, waiver or other Act, the Operating Partnership may at its option (but is not obligated to), by Board Resolution, fix in advance a record date for the determination of Holders of Registered Securities entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of Registered Securities of record at the close of business on such record date shall be deemed to be Holders for the purpose of determining whether Holders of the requisite proportion of Outstanding Securities have authorized, agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the Outstanding Securities shall be computed as of such record date; provided that no such authorization, agreement or consent by the Holders of Registered Securities shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than six months after the record date.

(6) Any request, demand, authorization, direction, notice, consent, waiver or other Act by the Holder of any Security shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof

or in exchange therefor or in lieu thereof in respect of anything done or suffered to be done by the Trustee, any Security Registrar, any Paying Agent, the Operating Partnership or the Guarantor in reliance thereon, whether or not notation of such Act is made upon such Security.

Section 105 Notices, etc. to Trustee, Operating Partnership and Guarantor.

Any request, demand, authorization, direction, notice, consent, waiver or other Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with,

(1) the Trustee by any Holder or the Operating Partnership shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing to or with the Trustee at its Corporate Trust Office, or

(2) the Operating Partnership by the Trustee or any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to the Operating Partnership addressed to the attention of its Secretary at the address of its principal office specified in the first paragraph of this instrument with the notation: “c/o Corporate Office Properties, L.P.” or at any other address furnished in writing to the Trustee by the Operating Partnership for such purpose, with a copy to the Guarantor addressed to the attention of its Legal Department at the address of its principal office specified in the first paragraph of this instrument or at any other address furnished in writing to the Trustee by the Guarantor for such purpose, or

(3) the Guarantor by the Trustee or any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to the Guarantor addressed to the attention of its Legal Department at the address of its principal office specified in the first paragraph of this instrument or at any other address furnished in writing to the Trustee by the Guarantor for such purpose.

Section 106 Notice to Holders of Securities; Waiver.

Except as otherwise expressly provided in or pursuant to this Indenture, where this Indenture provides for notice to Holders of Securities of any event,

(1) such notice shall be sufficiently given to Holders of Registered Securities if in writing and mailed, first-class postage prepaid, or if delivered electronically pursuant to the applicable procedures of the Depository, to each Holder of a Registered Security affected by such event, at his address as it appears in the Security Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice; and

(2) such notice shall be sufficiently given to Holders of Bearer Securities, if any, if published, at the expense of the Operating Partnership, in an Authorized Newspaper in The City of New York and, if such Securities are then listed on any stock

exchange outside the United States, in an Authorized Newspaper in such city as the Operating Partnership shall advise the Trustee in writing that such stock exchange so requires, on a Business Day at least twice, the first such publication to be not earlier than the earliest date and the second such publication not later than the latest date prescribed for the giving of such notice.

In any case where notice to Holders of Registered Securities is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder of a Registered Security shall affect the sufficiency of such notice with respect to other Holders of Registered Securities or the sufficiency of any notice to Holders of Bearer Securities given as provided herein. Any notice which is mailed in the manner herein provided shall be conclusively presumed to have been duly given or provided. In the case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee in its sole discretion shall constitute a sufficient notification for every purpose hereunder.

In case by reason of the suspension of publication of any Authorized Newspaper or Authorized Newspapers or by reason of any other cause it shall be impracticable to publish any notice to Holders of Bearer Securities as provided above, then such notification to Holders of Bearer Securities as shall be given with the approval of the Trustee in its sole discretion shall constitute sufficient notice to such Holders for every purpose hereunder. Neither failure to give notice by publication to Holders of Bearer Securities as provided above, nor any defect in any notice so published, shall affect the sufficiency of any notice mailed to Holders of Registered Securities as provided above.

Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders of Securities shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

Section 107 Language of Notices.

Any request, demand, authorization, direction, notice, consent, waiver or other action required or permitted under this Indenture shall be in the English language, except that, if the Operating Partnership or the Guarantor so elects, any published notice may be in an official language of the country of publication.

Section 108 Conflict with Trust Indenture Act.

If any provision of this Indenture limits, qualifies or conflicts with a provision of the Trust Indenture Act that is required under such Act to be a part of and govern this Indenture, the latter provision shall control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act that may be so modified or excluded, the latter provision shall be deemed to apply to this Indenture as so modified or to be excluded, as the case may be.

Unless otherwise specified in or pursuant to this Indenture or any Securities, in any case where any Interest Payment Date, Stated Maturity or Maturity of, or any other day on which a payment is due with respect to, any Security shall be a day which is not a Business Day, then payment need not be made on such day, but such payment may be made on the next succeeding day that is a relevant Business Day with the same force and effect as if made on the Interest Payment Date, at the Stated Maturity or Maturity or on any such other payment date, as the case may be, and no interest shall accrue or be payable on such succeeding Business Day for the period from and after such Interest Payment Date, Stated Maturity, Maturity or other payment date, as the case may be, to such succeeding Business Day.

The terms of the Securities of any series may provide, without limitation, that the Securities shall be authenticated and delivered by the Trustee on original issue from time to time upon written order of persons designated in the Board Resolutions of the Operating Partnership or the Guarantor (with respect to the Guarantee), Officers’ Certificate of the Operating Partnership or supplemental indenture, as the case may be, pertaining to such series of Securities and that such persons are authorized to determine, consistent with such Board Resolutions, Officers’ Certificate or supplemental indenture, such terms and conditions of the Securities of such series as are specified in such Board Resolutions, Officers’ Certificate or supplemental indenture.

All Securities of any one series need not be issued at the same time and, unless otherwise provided by the Operating Partnership as contemplated by this Section 301, a series may be reopened from time to time without notice to or the consent of any Holders for issuances of additional Securities of such series or to establish additional terms of such series of Securities.

Section 302 Currency; Denominations.

Unless otherwise provided in or pursuant to this Indenture, the principal of, any premium and interest on and any Additional Amounts with respect to the Securities shall be payable in Dollars.

Section 303 Execution, Authentication, Delivery and Dating.

Securities shall be executed on behalf of the Operating Partnership by the Chairman, President or one of the Vice Presidents and by the Treasurer, one of the Assistant Treasurers, the Controller, the Secretary or one of the Assistant Secretaries of the Guarantor, as the sole general partner of the Operating Partnership, and may (but need not) have its corporate seal or a facsimile thereof reproduced thereon. Xxxxxxx shall be executed on behalf of the Operating Partnership by the Chairman, the President or any Vice President of the Guarantor, as the sole general partner of the Operating Partnership. The signature of any of these officers on the Securities or any Coupons appertaining thereto may be manual or facsimile.

The Guarantee shall be executed on behalf of the Guarantor by any two of its authorized signatories. The signature of any of these signatories on the Guarantee may be manual or facsimile.

Securities and any Coupons appertaining thereto and the Guarantee bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Operating Partnership or the Guarantor, as applicable, shall, to the fullest extent permitted by law, bind the Operating Partnership and the Guarantor, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities or Coupons or the Guarantee.

At any time and from time to time after the execution and delivery of this Indenture, the Operating Partnership may deliver Securities, together with any Coupons appertaining thereto, executed by the Operating Partnership, to the Trustee for authentication and, provided that the Board Resolutions and Officers’ Certificate of the Operating Partnership or supplemental indenture or indentures with respect to such Securities referred to in Section 301 and an Operating Partnership Order for the authentication and delivery of such Securities have been delivered to the Trustee, the Trustee in accordance with the Operating Partnership Order and subject to the provisions hereof and of such Securities shall authenticate and deliver such Securities. The delivery of any Security by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Guarantee on behalf of the Guarantor. In authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities and any Coupons appertaining thereto, the Trustee shall receive, and (subject to Sections 315(a) through 315(d) of the Trust Indenture Act) shall be fully protected in conclusively relying upon, an Opinion of Counsel to the following effect, which Opinion of Counsel may contain such assumptions, qualifications and limitations as such counsel and Trustee shall deem appropriate:

(a) the form or forms and terms of such Securities and Coupons, if any, have been established in conformity with Sections 201 and 301 of this Indenture;

(b) all conditions precedent set forth in this Indenture to the authentication and delivery of such Securities and Coupons, if any, appertaining thereto have been complied with and that such Securities, and Coupons, when completed by appropriate insertions (if applicable), executed by duly authorized

officers of the Operating Partnership, delivered by duly authorized officers of the Operating Partnership to the Trustee for authentication pursuant to this Indenture, and authenticated and delivered by the Trustee and issued by the Operating Partnership in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and binding obligations of the Operating Partnership, enforceable against the Operating Partnership in accordance with their terms, and that the Guarantee, when executed by duly authorized signatories of the Guarantor and issued by the Guarantor in the manner and subject to any conditions specified in such Opinion of Counsel and when such Securities have been completed, executed and delivered by duly authorized officers of the Operating Partnership and authenticated and delivered by the Trustee, will constitute valid and binding obligations of the Guarantor, except , in each case, as enforcement thereof may be limited by bankruptcy, insolvency, reorganization, receivership, moratorium or other similar laws relating to or affecting creditors’ rights generally or by general principles of equity (regardless of whether enforcement is sought in a proceeding in equity or at law) and subject to such other exceptions as shall be acceptable to the Trustee; provided, that such Opinion of Counsel need express no opinion as to whether a court in the United States would render a money judgment in a currency other than that of the United States; and

(c) that all laws and requirements in respect of the execution and delivery by the Operating Partnership of such Securities and by the Guarantor of the Guarantee have been complied with.

If all the Securities of any series are not to be issued at one time, it shall not be necessary to deliver an Opinion of Counsel at the time of issuance of each Security, but such opinion, with such modifications as counsel shall deem appropriate, shall be delivered at or before the time of issuance of the first Security of such series. After any such first delivery, any separate request by the Operating Partnership that the Trustee authenticate Securities of such series for original issue will be accompanied by (i) a certification by the Operating Partnership that all conditions precedent provided for in this Indenture relating to authentication and delivery of such Securities continue to have been complied with and (ii) an Operating Partnership Order for the authentication and delivery of such Securities.

The Trustee shall not be required to authenticate or to cause an Authenticating Agent to authenticate any Securities if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or will otherwise be in a manner which is not reasonably acceptable to the Trustee or if the Trustee, being advised by counsel, determines that such action may not lawfully be taken.

Each Registered Security shall be dated the date of its authentication. Each Bearer Security and any Bearer Security in global form shall be dated as of the date specified in or pursuant to this Indenture.

No Security or Coupon appertaining thereto shall be entitled to any benefit under this Indenture or the Guarantee or be valid or obligatory for any purpose, unless there appears on

such Security a certificate of authentication substantially in the form provided for in Section 202 or 611 executed by or on behalf of the Trustee or by the Authenticating Agent by the manual signature of one of its authorized signatories. Such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. Except as permitted by Section 306 or 307 or as may otherwise be provided in or pursuant to this Indenture, the Trustee shall not authenticate and deliver any Bearer Security unless all Coupons appertaining thereto then matured have been detached and cancelled.

Section 304 Temporary Securities.

Pending the preparation of definitive Securities, the Operating Partnership may execute and deliver to the Trustee and, upon Operating Partnership Order, the Trustee or Authenticating Agent shall authenticate and deliver, in the manner provided in Section 303, temporary Securities in lieu thereof which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued, in registered form or, if authorized in or pursuant to this Indenture, in bearer form with one or more Coupons or without Coupons and with such appropriate insertions, omissions, substitutions and other variations as the officers of the Operating Partnership executing such Securities may determine, as conclusively evidenced by their execution of such Securities. Such temporary Securities may be in global form.

Except in the case of temporary Securities in global form, which shall be exchanged in accordance with the provisions set forth in this Indenture or the provisions established pursuant to Section 301, if temporary Securities are issued, the Operating Partnership shall cause definitive Securities to be prepared without unreasonable delay. Except as otherwise provided in or pursuant to this Indenture, after the preparation of definitive Securities of the same series and containing terms and provisions that are identical to those of any temporary Securities, such temporary Securities shall be exchangeable for such definitive Securities upon surrender of such temporary Securities at an Office or Agency for such Securities, without charge to any Holder thereof. Except as otherwise provided in or pursuant to this Indenture, upon surrender for cancellation of any one or more temporary Securities (accompanied by any unmatured Coupons appertaining thereto), the Operating Partnership shall execute and, upon Operating Partnership Order, the Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Securities of authorized denominations of the same series and containing identical terms and provisions; provided, however, that no definitive Bearer Security, except as provided in or pursuant to this Indenture, shall be delivered in exchange for a temporary Registered Security; and provided, further, that a definitive Bearer Security shall be delivered in exchange for a temporary Bearer Security only in compliance with the conditions set forth in or pursuant to this Indenture. Unless otherwise provided in or pursuant to this Indenture with respect to a temporary global Security, until so exchanged the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture and the Guarantee as definitive Securities of such series.

Section 305 Registration, Transfer and Exchange.

(1) With respect to the Registered Securities of each series, if any, the Operating Partnership shall cause to be kept a register (each such register being herein

sometimes referred to as the “Security Register”) at an Office or Agency for such series in which, subject to such reasonable regulations as it may prescribe, the Operating Partnership shall provide for the registration of the Registered Securities of such series and of transfers of the Registered Securities of such series. Such Office or Agency shall be the “Security Registrar” for that series of Securities. Unless otherwise specified in or pursuant to this Indenture or the Securities, the initial Security Registrar for each series of Securities shall be as specified in the last paragraph of Section 1002. The Operating Partnership shall have the right to remove and replace from time to time the Security Registrar for any series of Securities; provided that no such removal or replacement shall be effective until a successor Security Registrar with respect to such series of Securities shall have been appointed by the Operating Partnership and shall have accepted such appointment. In the event that the Trustee shall not be or shall cease to be Security Registrar with respect to a series of Securities, it shall have the right to examine the Security Register for such series at all reasonable times. There shall be only one Security Register for each series of Securities.

Except as otherwise provided in or pursuant to this Indenture, upon surrender for registration of transfer of any Registered Security of any series at any Office or Agency for such series, the Operating Partnership shall execute, and, upon Operating Partnership Order, the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Registered Securities of the same series denominated as authorized in or pursuant to this Indenture, of a like aggregate principal amount bearing a number not contemporaneously outstanding and containing identical terms and provisions.

Except as otherwise provided in or pursuant to this Indenture, at the option of the Holder, Registered Securities of any series may be exchanged for other Registered Securities of the same series containing identical terms and provisions, in any authorized denominations, and of a like aggregate principal amount, upon surrender of the Securities to be exchanged at any Office or Agency for such series. Whenever any Registered Securities are so surrendered for exchange, the Operating Partnership shall execute, and, upon Operating Partnership Order, the Trustee shall authenticate and deliver, the Registered Securities which the Holder making the exchange is entitled to receive.

If provided in or pursuant to this Indenture, with respect to Securities of any series, at the option of the Holder, Bearer Securities of such series may be exchanged for Registered Securities of such series containing identical terms, denominated as authorized in or pursuant to this Indenture and in the same aggregate principal amount, upon surrender of the Bearer Securities to be exchanged at any Office or Agency for such series, with all unmatured Coupons and all matured Coupons in default thereto appertaining. If the Holder of a Bearer Security is unable to produce any such unmatured Coupon or Coupons or matured Coupon or Coupons in default, such exchange may be effected if the Bearer Securities are accompanied by payment in funds acceptable to the Operating Partnership and the Trustee in an amount equal to the face amount of such missing Coupon or Coupons, or the surrender of such missing Coupon or Coupons may be waived by the Operating Partnership and the Trustee if there is furnished to them such security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Bearer Security shall surrender to any Paying Agent any such missing Coupon in respect of which such a payment shall have been made, such Holder

shall be entitled to receive the amount of such payment; provided, however, that, except as otherwise provided in Section 1002, interest represented by Coupons shall be payable only upon presentation and surrender of those Coupons at an Office or Agency for such series located outside the United States. Notwithstanding the foregoing, in case a Bearer Security of any series is surrendered at any such Office or Agency for such series in exchange for a Registered Security of such series and like tenor after the close of business at such Office or Agency on (i) any Regular Record Date and before the opening of business at such Office or Agency on the relevant Interest Payment Date, or (ii) any Special Record Date and before the opening of business at such Office or Agency on the related date for payment of Defaulted Interest, such Bearer Security shall be surrendered without the Coupon relating to such Interest Payment Date or proposed date of payment, as the case may be (or, if such Coupon is so surrendered with such Bearer Security, such Coupon shall be returned to the Person so surrendering the Bearer Security), and interest or Defaulted Interest, as the case may be, shall not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of the Registered Security issued in exchange for such Bearer Security, but shall be payable only to the Holder of such Coupon when due in accordance with the provisions of this Indenture.

If provided in or pursuant to this Indenture with respect to Securities of any series, at the option of the Holder, Registered Securities of such series may be exchanged for Bearer Securities upon such terms and conditions as may be provided in or pursuant to this Indenture with respect to such series.

Whenever any Securities are surrendered for exchange as contemplated by the immediately preceding two paragraphs, the Operating Partnership shall execute, and, upon Operating Partnership Order, the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive.

Notwithstanding the foregoing, except as otherwise provided in or pursuant to this Indenture, the global Securities of any series shall be exchangeable for definitive certificated Securities of such series only if (i) the Depository for such global Securities notifies the Operating Partnership that it is unwilling or unable or no longer qualified to continue as a Depository for such global Securities or at any time the Depository for such global Securities ceases to be a clearing agency registered as such under the Exchange Act, if so required by applicable law or regulation, and no successor Depository for such Securities shall have been appointed by the Operating Partnership within 90 days of such notification or of the Operating Partnership becoming aware of the Depository’s ceasing to be so registered, as the case may be, (ii) the Operating Partnership, in its sole discretion, determines that the Securities of such series shall no longer be represented by one or more global Securities and executes and delivers to the Trustee an Operating Partnership Order to the effect that such global Securities shall be so exchangeable or (iii) an Event of Default has occurred and is continuing with respect to such Securities and the Depository or the Operating Partnership specifically requests such exchange.

If the beneficial owners of interests in a global Security are entitled to exchange such interests for definitive Securities as the result of an event described in clause (i), (ii) or (iii) of the preceding paragraph, then without unnecessary delay but in any event not later than the earliest date on which such interests may be so exchanged, the Operating Partnership shall deliver to the Trustee definitive Securities in such form and denominations as are required by or pursuant to

this Indenture, and of the same series, containing identical terms and in aggregate principal amount equal to the principal amount of such global Security, executed by the Operating Partnership. On or after the earliest date on which such interests may be so exchanged, such global Security shall be surrendered from time to time by the Depository (or its custodian) as shall be specified in the Operating Partnership Order with respect thereto (which the Operating Partnership agrees to deliver), and in accordance with instructions given to the Trustee and the Depository as shall be specified in the Operating Partnership Order with respect thereto to the Trustee, as the Operating Partnership’s agent for such purpose, to be exchanged, in whole or in part, for definitive Securities as described above without charge. The Trustee shall authenticate and make available for delivery, in exchange for each portion of such surrendered global Security, a like aggregate principal amount of definitive Securities of the same series of authorized denominations and of like tenor as the portion of such global Security to be exchanged, which (unless such Securities are not issuable both as Bearer Securities and as Registered Securities, in which case the definitive Securities exchanged for the global Security shall be issuable only in the form in which the Securities are issuable, as provided in or pursuant to this Indenture) shall be in the form of Bearer Securities or Registered Securities, or any combination thereof, and which shall be in such denominations and, in the case of Registered Securities, registered in such names, as shall be specified by the Depository, but subject to the satisfaction of any certification or other requirements to the issuance of Bearer Securities; provided, however, that no such exchanges may occur during a period beginning at the opening of business 15 days before any selection of Securities of the same series to be redeemed and ending on the relevant Redemption Date; and provided, further, that (unless otherwise provided in or pursuant to this Indenture) no Bearer Security delivered in exchange for a portion of a global Security shall be mailed or otherwise delivered to any location in the United States. Promptly following any such exchange in part, such global Security shall be returned by the Trustee to such Depository (or its custodian) or such other Depository (or its custodian) referred to above in accordance with the instructions of the Operating Partnership referred to above, and the Trustee shall endorse such global Security to reflect the decrease in the principal amount thereof resulting from such exchange. If a Registered Security is issued in exchange for any portion of a global Security after the close of business at the Office or Agency for such Security where such exchange occurs on or after (i) any Regular Record Date for such Security and before the opening of business at such Office or Agency on the next Interest Payment Date, or (ii) any Special Record Date for such Security and before the opening of business at such Office or Agency on the related proposed date for payment of interest or Defaulted Interest, as the case may be, interest shall not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of such Registered Security, but shall be payable on such Interest Payment Date or proposed date for payment, as the case may be, only to the Person to whom interest in respect of such portion of such global Security shall be payable in accordance with the provisions of this Indenture.

All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Operating Partnership evidencing the same debt and entitling the Holders thereof to the same benefits under this Indenture and the Guarantee as the Securities surrendered upon such registration of transfer or exchange.

Every Registered Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Operating Partnership or the Security Registrar for such

Security) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Operating Partnership and the Security Registrar for such Security duly executed by the Holder thereof or his attorney duly authorized in writing.

No service charge shall be made for any registration of transfer or exchange of Securities, or any redemption or repayment of Securities, or any conversion or exchange of Securities for other types of securities or property, but the Operating Partnership may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 304, 905 or 1107, upon repayment or repurchase in part of any Registered Security pursuant to Article Thirteen, or upon surrender in part of any Registered Security for conversion or exchange into Common Equity or other securities or property pursuant to its terms, in each case not involving any transfer.

Except as otherwise provided in or pursuant to this Indenture, the Operating Partnership shall not be required (i) to issue, register the transfer of or exchange any Securities during a period beginning at the opening of business 15 days before the day of the selection for redemption of Securities of like tenor and terms and of the same series under Section 1103 and ending at the close of business on the day of such selection, or (ii) to register the transfer of or exchange any Registered Security, or portion thereof, so selected for redemption, except in the case of any Registered Security to be redeemed in part, the portion thereof not to be redeemed, or (iii) to exchange any Bearer Security so selected for redemption except, to the extent provided with respect to such Bearer Security, that such Bearer Security may be exchanged for a Registered Security of like tenor and terms and of the same series, provided that such Registered Security shall be simultaneously surrendered for redemption with written instruction for payment consistent with the provisions of this Indenture or (iv) to issue, register the transfer of or exchange any Security which, in accordance with its terms, has been surrendered for repayment at the option of the Holder pursuant to Article Thirteen and not withdrawn, except the portion, if any, of such Security not to be so repaid.

Section 306 Mutilated, Destroyed, Lost and Stolen Securities.

If any mutilated Security or a Security with a mutilated Coupon appertaining to it is surrendered to the Trustee, subject to the provisions of this Section 306, the Operating Partnership shall execute and, upon Operating Partnership Order, the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series containing identical terms and of like principal amount and bearing a number not contemporaneously outstanding, with Coupons appertaining thereto corresponding to the Coupons, if any, appertaining to the surrendered Security.

If there be delivered to the Operating Partnership and to the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security or Coupon, and (ii) such security or indemnity as may be reasonably required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Operating Partnership or the Trustee that such Security or Coupon has been acquired by a bona fide purchaser, the Operating Partnership shall execute and, upon the Operating Partnership’s written request the Trustee shall authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Security or

in exchange for the Security to which a destroyed, lost or stolen Coupon appertains with all appurtenant Coupons not destroyed, lost or stolen, a new Security of the same series containing identical terms and of like principal amount and bearing a number not contemporaneously outstanding, with Coupons corresponding to the Coupons, if any, appertaining to such destroyed, lost or stolen Security or to the Security to which such destroyed, lost or stolen Coupon appertains.

Notwithstanding the foregoing provisions of this Section 306, in case any mutilated, destroyed, lost or stolen Security or Coupon has become or is about to become due and payable, the Operating Partnership in its discretion may, instead of issuing a new Security, pay such Security or Coupon; provided, however, that payment of principal of, any premium or interest on or any Additional Amounts with respect to any Bearer Securities shall, be payable only at an Office or Agency for such Securities located outside the United States and, unless otherwise provided in or pursuant to this Indenture, any interest on Bearer Securities and any Additional Amounts with respect to such interest shall be payable only upon presentation and surrender of the Coupons appertaining thereto.

Upon the issuance of any new Security under this Section, the Operating Partnership may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee and its legal counsel) connected therewith.

Every new Security and any Coupons appertaining thereto issued pursuant to this Section in lieu of any destroyed, lost or stolen Security, or in exchange for a Security to which a destroyed, lost or stolen Coupon appertains’ shall constitute a separate obligation of the Operating Partnership, whether or not the destroyed, lost or stolen Security and Coupons appertaining thereto or the destroyed, lost or stolen Coupon shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture and the Guarantee equally and proportionately with any and all other Securities of such series and any Coupons, if any, duly issued hereunder.

The provisions of this Section, as amended or supplemented pursuant to this Indenture with respect to particular Securities or generally, shall (to the extent lawful) be exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities or Coupons.

Section 307 Payment of Interest and Certain Additional Amounts; Rights to Interest and Certain Additional Amounts Preserved.

Unless otherwise provided in or pursuant to this Indenture, any interest on and any Additional Amounts with respect to any Registered Security which shall be payable, and are punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name such Security (or one or more Predecessor Securities) is registered as of the close of business on the Regular Record Date for such interest. Unless otherwise provided in or pursuant to this Indenture, in case a Bearer Security is surrendered in exchange for a Registered Security after the close of business at an Office or Agency for such Security on any Regular Record Date therefor and before the opening of business at such Office or Agency on the next succeeding

Interest Payment Date therefor, such Bearer Security shall be surrendered without the Coupon relating to such Interest Payment Date and interest shall not be payable on such Interest Payment Date in respect of the Registered Security issued in exchange for such Bearer Security, but shall be payable only to the Holder of such Coupon when due in accordance with the provisions of this Indenture.

Unless otherwise provided in or pursuant to this Indenture, any interest on and any Additional Amounts with respect to any Registered Security which shall be payable, but shall not be punctually paid or duly provided for, on any Interest Payment Date for such Registered Security (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Holder thereof on the relevant Regular Record Date by virtue of having been such Holder; and such Defaulted Interest may be paid by the Operating Partnership, at its election in each case, as provided in clause (1) or (2) below:

(1) The Operating Partnership may elect to make payment of any Defaulted Interest to the Person in whose name such Registered Security (or a Predecessor Security thereof) shall be registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Operating Partnership shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on such Registered Security and the date of the proposed payment, and at the same time the Operating Partnership shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when so deposited to be held in trust for the benefit of the Person entitled to such Defaulted Interest as in this clause provided. Thereupon, the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Operating Partnership of such Special Record Date and, in the name and at the expense of the Operating Partnership shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to the Holder of such Registered Security (or a Predecessor Security thereof) at his address as it appears in the Security Register not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the Person in whose name such Registered Security (or a Predecessor Security thereof) shall be registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (2). In case a Bearer Security is surrendered at the Office or Agency for such Security in exchange for a Registered Security after the close of business at such Office or Agency on any Special Record Date and before the opening of business at such Office or Agency on the related proposed date for payment of Defaulted Interest, such Bearer Security shall be surrendered without the Coupon relating to such Defaulted Interest and Defaulted Interest shall not be payable on such proposed date of payment in respect of the Registered Security issued in exchange for such Bearer Security, but shall be payable only to the Holder of such Coupon when due in accordance with the provisions of this Indenture; or

(2) The Operating Partnership may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Security may be listed, and upon such notice as may be required by such exchange, if, after written notice given by the Operating Partnership to the Trustee of the proposed payment pursuant to this clause, such payment shall be deemed practicable by the Trustee.

Unless otherwise provided in or pursuant to this Indenture or the Securities of any particular series, at the option of the Operating Partnership, interest on Registered Securities on any Interest Payment Date may be paid by mailing a check to the address of the Person entitled thereto as such address shall appear in the Security Register or by transfer to an account maintained by the payee with a bank located in the United States of America.

Subject to the foregoing provisions of this Section and Section 305, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security.

Section 308 Persons Deemed Owners.

Prior to due presentment of a Registered Security for registration of transfer, the Operating Partnership, the Guarantor, the Trustee and any agent of the Operating Partnership, the Guarantor or the Trustee may treat the Person in whose name such Registered Security is registered in the Security Register as the owner of such Registered Security for the purpose of receiving payment of principal of, any premium and (subject to Sections 305 and 307) interest on and any Additional Amounts with respect to such Registered Security and for all other purposes whatsoever, whether or not any payment with respect to such Registered Security shall be overdue, and none of the Operating Partnership, the Guarantor, the Trustee or any agent of the Operating Partnership, the Guarantor or the Trustee shall be affected by notice to the contrary.

The Operating Partnership, the Guarantor, the Trustee and any agent of the Operating Partnership, the Guarantor or the Trustee may treat the bearer of any Bearer Security or the bearer of any Coupon as the absolute owner of such Security or Coupon for the purpose of receiving payment thereof or on account thereof and for all other purposes whatsoever, whether or not any payment with respect to such Security or Coupon shall be overdue, and none of the Operating Partnership, the Guarantor, the Trustee or any agent of the Operating Partnership, the Guarantor or the Trustee shall be affected by notice to the contrary.

No owner of any beneficial interest in any global Security held on its behalf by a Depository shall have any rights under this Indenture with respect to such global Security, and such Depository may be treated by the Operating Partnership, the Guarantor, the Trustee and any agent of the Operating Partnership, the Guarantor or the Trustee as the owner of such global Security for all purposes whatsoever. None of the Operating Partnership, the Guarantor, the Trustee or any agent of the Operating Partnership, the Guarantor or 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 of a global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

Notwithstanding the foregoing, nothing herein shall prevent the Operating Partnership, the Guarantor, the Trustee or any agent of the Operating Partnership, the Guarantor or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the applicable Depository, as a Holder, with respect to a global Security or impair, as between such Depository and the owners of beneficial interests in such global Security, the operation of customary practices governing the exercise of the rights of such Depository (or its nominee) as the Holder of such global Security.

Section 309 Cancellation.

All Securities and Coupons surrendered for payment, redemption, registration of transfer, exchange or conversion or for credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be promptly delivered to the Trustee, and any such Securities and Coupons, as well as Securities and Coupons surrendered directly to the Trustee for any such purpose, shall be cancelled promptly by the Trustee. The Operating Partnership may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Operating Partnership may have acquired in any manner whatsoever, and all Securities so delivered shall be cancelled promptly by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by or pursuant to this Indenture. All cancelled Securities and Coupons held by the Trustee shall be disposed of by the Trustee in accordance with its customary procedures, unless by an Operating Partnership Order the Operating Partnership directs their return to it.

Section 310 Computation of Interest.

Except as otherwise provided in or pursuant to this Indenture or in the Securities of any series, interest on the Securities shall be computed on the basis of a 360-day year of twelve 30-day months.

Section 311 CUSIP Numbers.

The Operating Partnership in issuing the Securities may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Operating Partnership will promptly notify the Trustee in writing of any change in the “CUSIP” numbers.

(1) Unless, pursuant to Section 301, either or both of (i) defeasance of the Securities of or within a series under clause (2) of this Section 402 or (ii) covenant defeasance of the Securities of or within a series under clause (3) of this Section 402 shall not be applicable with respect to the Securities of such series, then such provisions, together with the other provisions of this Section 402 (with such modifications thereto as may be specified pursuant to Section 301 with respect to any Securities), shall be applicable to such Securities and any Coupons appertaining thereto, and the Operating Partnership may at its option by Board Resolution, at any time, with respect to the Securities of or within such series and any Coupons appertaining thereto, elect to have Section 402(2) or Section 402(3) be applied to such Outstanding Securities and any Coupons appertaining thereto upon compliance with the conditions set forth below in this Section 402. Unless otherwise specified pursuant to Section 301 with respect to the Securities of any series, defeasance under clause (2) of this Section 402 and covenant defeasance under clause (3) of this Section 402 may be effected only with respect to all, and not less than all, of the Outstanding Securities of any series. To the extent that the terms of any Security or Coupon appertaining thereto established in or pursuant to this Indenture permit the Operating Partnership or any Holder thereof to extend the date on which any payment of principal of, or premium, if any, or interest, if any, on, or Additional Amounts, if any, with respect to such Security or Coupon is due and payable, then unless otherwise provided pursuant to Section 301, the right to extend such date shall terminate upon defeasance or covenant defeasance, as the case may be.

(2) Upon the Operating Partnership’s exercise of the above option applicable to this Section 402(2) with respect to any Securities of or within a series, the Operating Partnership shall be deemed to have been discharged from its obligations with respect to such Outstanding Securities and any Coupons appertaining thereto on the date the conditions set forth in clause (4) of this Section 402 are satisfied (hereinafter, “defeasance”). For this purpose, such defeasance means that the Operating Partnership shall be deemed to have paid and discharged the entire indebtedness represented by such Outstanding Securities and any Coupons appertaining thereto, which shall thereafter be deemed to be “Outstanding” only for the purposes of clause (5) of this Section 402 and the other Sections of this Indenture referred to in subclauses (i) through (iv) of this clause (2), and to have satisfied all of its other obligations under such Securities and any Coupons appertaining thereto and this Indenture insofar as such Securities and any Coupons appertaining thereto are concerned (and the Trustee, at the expense of the Operating Partnership, shall execute proper instruments acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder: (i) the rights of Holders of such Outstanding Securities and any Coupons appertaining

thereto to receive, solely (except as provided in subclause (ii) below) from the trust fund described in clause (4)(a) of this Section 402 and as more fully set forth in this Section 402 and 403, payments in respect of the principal of (and premium, if any) and interest, if any, on, and Additional Amounts, if any, with respect to, such Securities and any Coupons appertaining thereto when such payments are due, (ii) the obligations of the Operating Partnership and the Trustee with respect to such Securities under Sections 304, 305, 306, 1002, 1003 and, if applicable to the Securities of such series, 1004 (including, without limitation, with respect to the payment of Additional Amounts, if any, with respect to such Securities as contemplated by Section 1004, but only to the extent that the Additional Amounts payable with respect to such Securities exceed the amount deposited in respect of such Additional Amounts pursuant to clause (4)(a) of this Section 402)), the obligations of the Guarantor under the Guarantee in respect of Additional Amounts, any rights of Holders of such Securities (unless otherwise provided pursuant to Section 301 with respect to the Securities of such series) to require the Operating Partnership to repurchase or repay, and the obligations of the Operating Partnership to repurchase or repay, such Securities at the option of the Holders pursuant to Article Thirteen hereof, and any rights of Holders of such Securities (unless otherwise provided pursuant to Section 301 with respect to the Securities of such series) to convert or exchange, and the obligations of the Operating Partnership to convert or exchange, such Securities into Common Equity or other securities or property, (iii) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (iv) this Section 402 and Sections 403 and 404. The Operating Partnership may exercise its option under this Section 402(2) notwithstanding the prior exercise of its option under Section 402(3) with respect to such Securities and any Coupons appertaining thereto.

(3) Upon the Operating Partnership’s exercise of the above option applicable to this Section 402(3) with respect to any Securities of or within a series, each of the Operating Partnership and the Guarantor shall be released from its obligations under clause (ii) of Section 1005 and, to the extent specified pursuant to Section 301, any other covenant applicable to such Securities with respect to such Securities and any Coupons appertaining thereto shall cease to be applicable to such Securities on and after the date the conditions set forth in clause (4) of this Section 402 are satisfied (hereinafter, “covenant defeasance”), and such Securities and any Coupons appertaining thereto shall thereafter be deemed to be not “Outstanding” for the purposes of any direction, waiver, consent or declaration or Act of Holders (and the consequences of any thereof) in connection with any such covenant, but shall continue to be deemed “Outstanding” for all other purposes hereunder. For this purpose, such covenant defeasance means, with respect to such Outstanding Securities and any Coupons appertaining thereto, each of the Operating Partnership and the Guarantor may omit to comply with, and shall have no liability in respect of, any term, condition or limitation set forth in any such Section or any such other covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such Section or such other covenant or by reason of reference in any such Section or such other covenant to any other provision herein or in any other document and such omission to comply shall not constitute a default or an Event of Default under Section 501(3) or 501(4), as the case may be, but, except as specified above, the remainder of this Indenture and such Securities and Coupons appertaining thereto shall be unaffected thereby.

(4) The following shall be the conditions to application of clause (2) or (3) of this Section 402 to any Outstanding Securities of or within a series and any Coupons appertaining thereto:

The Operating Partnership must specify whether the Securities are being defeased to such stated date for payment or to a particular Redemption Date.

(c) No Event of Default or event which, with notice or lapse of time or both, would become an Event of Default with respect to such Securities and any Coupons appertaining thereto shall have occurred and be continuing on the date of such deposit, and, solely in the case of defeasance under Section 402(2), no Event of Default with respect to such Securities and any Coupons appertaining thereto under clause (5), (6) or (7) of Section 501 or event which with notice or lapse of time or both would become an Event of Default with respect to such Securities and any Coupons appertaining thereto under clause (5), (6) or (7) of Section 501 shall have occurred and be continuing at any time during the period ending on and including the 91st day after the date of such deposit (it being understood that this condition to defeasance under Section 402(2) shall not be deemed satisfied until the expiration of such period).

(d) In the case of defeasance pursuant to Section 402(2), the Operating Partnership shall have delivered to the Trustee an opinion of independent counsel acceptable to the Trustee stating that (x) the Operating Partnership has received from, or there has been published by, the Internal Revenue Service a ruling, or (y) since the date of this Indenture there has been a change in applicable federal income tax law, in either case to the effect that, and based thereon such opinion of independent counsel shall confirm that, the Holders and beneficial owners of such Outstanding Securities and any Coupons appertaining thereto will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such 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 had not occurred; or, in the case of covenant defeasance pursuant to Section 402(3), the Operating Partnership shall have delivered to the Trustee an opinion of independent counsel reasonably acceptable to the Trustee to the effect that the Holders and beneficial owners of such Outstanding Securities and any Coupons appertaining thereto will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such 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 covenant defeasance had not occurred.

(e) The Operating Partnership must deliver to the Trustee an Officers’ Certificate stating that the deposit was not made by the Operating Partnership with the intent of preferring the Holders of Securities over the other creditors of the Operating Partnership with the intent of defeating, hindering, delaying or defrauding any creditors of the Operating Partnership or others.

(f) The Operating Partnership shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent to the defeasance or covenant defeasance, as the case may be, under this Indenture have been complied with.

(g) If the monies or Government Obligations or combination thereof, as the case may be, deposited under subclause (a) above are sufficient to pay the

principal of, and premium, if any, and interest, if any, on and, to the extent provided in such subclause (a), Additional Amounts with respect to, such Securities on a particular Redemption Date, the Operating Partnership shall have given the Trustee irrevocable instructions to redeem such Securities on such date and to provide notice of such redemption to Holders as provided in or pursuant to this Indenture.

(h) Notwithstanding any other provisions of this Section 402(4), such defeasance or covenant defeasance shall be effected in compliance with any additional or substitute terms, conditions or limitations which may be imposed on the Operating Partnership in connection therewith pursuant to Section 301.

Unless otherwise specified in or pursuant to this Indenture or any Securities, if, after a deposit referred to in Section 402(4)(a) has been made, (a) the Holder of a Security in respect of which such deposit was made is entitled to, and does, elect pursuant to Section 301 or the terms of such Security to receive payment in a Currency other than that in which the deposit pursuant to Section 402(4)(a) has been made in respect of such Security, or (b) a Conversion Event occurs in respect of the Foreign Currency in which the deposit pursuant to Section 402(4)(a) has been made, the indebtedness represented by such Security and any Coupons appertaining thereto shall be deemed to have been, and will be, fully discharged and satisfied through the payment of the principal of (and premium, if any), and interest, if any, on, and Additional Amounts, if any, with respect to, such Security as the same becomes due out of the proceeds yielded by converting (from time to time as specified below in the case of any such election) the amount or other property deposited in respect of such Security into the Currency in which such Security becomes payable as a result of such election or Conversion Event based on (x) in the case of payments made pursuant to subclause (a) above, the applicable market exchange rate for such Currency in effect on the second Business Day prior to each payment date, or (y) with respect to a Conversion Event, the applicable market exchange rate for such Foreign Currency in effect (as nearly as feasible) at the time of the Conversion Event.

The Operating Partnership shall pay and indemnify the Trustee against any tax, fee or other charge, imposed on or assessed against the Government Obligations deposited pursuant to

this Section 402 or the principal or interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of such Outstanding Securities and any Coupons appertaining thereto.

Anything in this Section 402 to the contrary notwithstanding, the Trustee shall deliver or pay to the Operating Partnership from time to time upon Operating Partnership Request any money or Government Obligations (or other property and any proceeds therefrom) held by it as provided in clause (4)(a) of this Section 402 which, in the written opinion of a nationally recognized firm of independent public accountants delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect a defeasance or covenant defeasance, as applicable, in accordance with this Section 402.

Section 403 Application of Trust Money.

Subject to the provisions of the last paragraph of Section 1003, all money and Government Obligations deposited with the Trustee pursuant to Section 401 or 402 shall be held in trust and applied by it, in accordance with the provisions of the Securities, the Coupons and this Indenture, to the payment, either directly or through any Paying Agent (including the Operating Partnership acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal, premium, interest and Additional Amounts for whose payment such money has or Government Obligations have been deposited with or received by the Trustee; but such money and Government Obligations need not be segregated from other funds except to the extent required by law.

Section 502 Acceleration of Maturity; Rescission and Annulment.

If an Event of Default (other than an Event of Default specified in clause (5), (6) or (7) of Section 501) with respect to Securities of any series occurs and is continuing, then either the Trustee or the Holders of not less than 25% in aggregate principal amount of the Outstanding Securities of such series may declare the principal of all the Securities of such series, or such lesser amount as may be provided for in the Securities of such series, and accrued and unpaid interest, if any, thereon to be due and payable immediately, by a notice in writing to the Operating Partnership and the Guarantor (and to the Trustee if given by the Holders), and upon any such declaration such principal or such lesser amount, as the case may be, and such accrued and unpaid interest shall become immediately due and payable. If an Event of Default specified in clause (5), (6) or (7) of Section 501 with respect to the Securities of any series occurs, then the principal of all of the Securities of such series, or such lesser amount as may be provided for in the Securities of such series, and accrued and unpaid interest, if any, thereon shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder of the Securities of such series.

At any time after Securities of any series have been accelerated by declaration of the Trustee or the Holders and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in aggregate principal amount of the Outstanding Securities of such series, by written notice to the

Operating Partnership, the Guarantor and the Trustee, may rescind and annul such declaration and its consequences if

(1) the Operating Partnership or the Guarantor has paid or deposited, or cause to be paid or deposited, with the Trustee a sum of money sufficient to pay (or, to the extent that the terms of the Securities of such series established pursuant to Section 301 expressly provide for payment to be made in shares of Common Equity or other securities or property, shares of Common Equity or other securities or property, together with cash in lieu of fractional shares or securities, sufficient to pay)

(a) all overdue installments of any interest on any Securities of such series and any Coupons appertaining thereto which have become due otherwise than by such declaration of acceleration and any Additional Amounts with respect thereto,

(b) the principal of and any premium on any Securities of such series which have become due otherwise than by such declaration of acceleration and any Additional Amounts with respect thereto and, to the extent permitted by applicable law, interest thereon at the rate or respective rates, as the case may be, provided for in or with respect to such Securities, or, if no such rate or rates are so provided, at the rate or respective rates, as the case may be, of interest borne by such Securities,

(c) to the extent permitted by applicable law, interest upon installments of any interest, if any, which have become due otherwise than by such declaration of acceleration and any Additional Amounts with respect thereto at the rate or respective rates, as the case may be, provided for in or with respect to such Securities, or, if no such rate or rates are so provided, at the rate or respective rates, as the case may be, of interest borne by such Securities, and

(d) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and all other amounts due the Trustee under Section 606; and

(2) all Events of Default with respect to Securities of such series other than the non-payment of the principal of, any premium and interest on, and any Additional Amounts with respect to Securities of such series which shall have become due solely by such declaration of acceleration, shall have been waived as provided in Section 513 or cured.

No such rescission shall affect any subsequent default or impair any right consequent thereon.

Section 503 Collection of Indebtedness and Suits for Enforcement by Trustee.

The Operating Partnership covenants that if:

(1) default is made in the payment of any interest on, or any Additional Amounts payable in respect of any interest on, any Security or any Coupon appertaining thereto when such interest or Additional Amounts, as the case may be, shall have become due and payable and such default continues for a period of 30 days, or

(2) default is made in the payment of any principal of or premium, if any, on, or any Additional Amounts payable in respect of any principal of or premium, if any, on, any Security at its Maturity, and such default continues for three Business Days, or

(3) default is made in the deposit of any sinking fund payment, if applicable, when due, and such default continues for three Business Days,

the Operating Partnership or the Guarantor shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of such Securities and any Coupons appertaining thereto, the whole amount of money then due and payable with respect to such Securities and any Coupons appertaining thereto, with interest upon the overdue principal, any premium and, to the extent permitted by applicable law, upon any overdue installments of interest and Additional Amounts at the rate or respective rates, as the case may be, provided for or with respect to such Securities or, if no such rate or rates are so provided, at the rate or respective rates, as the case may be, of interest borne by such Securities, and, in addition thereto, such further amount of money as shall be sufficient to cover the reasonable costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and all other amounts due to the Trustee under Section 606.

If each of the Operating Partnership and the Guarantor fails to pay the money it is required to pay the Trustee pursuant to the preceding paragraph forthwith upon the demand of the Trustee, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the money so due and unpaid, and may prosecute such proceeding to judgment or final decree, and may enforce the same against the Operating Partnership, the Guarantor or any other obligor upon such Securities and any Coupons appertaining thereto and collect the monies adjudged or decreed to be payable in the manner provided by law out of the property of the Operating Partnership, the Guarantor or any other obligor upon such Securities and any Coupons appertaining thereto, wherever situated.

If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities of such series and any Coupons appertaining thereto by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or such Securities or in aid of the exercise of any power granted herein or therein, or to enforce any other proper remedy.

Section 504 Trustee May File Proofs of Claim.

the Operating Partnership, the Guarantor or such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Operating Partnership or the Guarantor for the payment of any overdue principal, premium, interest or Additional Amounts) shall be entitled and empowered, by intervention in such proceeding or otherwise,

(1) to file and prove a claim for the whole amount, or such lesser amount as may be provided for in the Securities of such series, of the principal and any premium, interest and Additional Amounts owing and unpaid in respect of the Securities and any Coupons appertaining thereto and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents or counsel) and of the Holders of Securities or any Coupons allowed in such judicial proceeding, and

(2) to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder of Securities or any Coupons to make such payments to the Trustee and, in the event that the Trustee shall consent in writing in its sole discretion to the making of such payments directly to the Holders of Securities or any Coupons, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee (acting in any capacity hereunder), its agents and counsel and any other amounts due the Trustee hereunder.

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder of a Security or any Coupon any plan of reorganization, arrangement, adjustment or composition affecting the Securities or Coupons or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder of a Security or any Coupon in any such proceeding.

Section 506 Application of Money Collected.

Any money collected by the Trustee pursuant to this Article Five with respect to the Securities of any series shall be applied in the following order, at the date or dates fixed by the

Trustee and, in case of the distribution of such money on account of principal, or any premium, interest or Additional Amounts, upon presentation of such Securities or the Coupons, if any, appertaining thereto, or both, as the case may be, and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

THIRD: The balance, if any, to the Person or Persons entitled thereto.

Section 507 Limitations on Suits.

No Holder of any Security of any series or any Coupons appertaining thereto shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless

(1) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities of such series;

(4) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and

(5) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in aggregate principal amount of the Outstanding Securities of such series;

it being understood and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture or any Security to affect, disturb or prejudice the rights of any other such Holders or Holders of Securities of any other series, or to obtain or to seek to obtain priority or preference over any other Holders or to

enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all such Holders.

Section 508 Unconditional Right of Holders to Receive Principal and any Premium, Interest and Additional Amounts.

Notwithstanding any other provision in this Indenture, the Holder of any Security or Coupon shall have the right, which is absolute and unconditional, to receive payment of the principal of, and premium, if any, and (subject to Sections 305 and 307) interest, if any, on and any Additional Amounts with respect to such Security or such Coupon, as the case may be, on the respective Stated Maturity or Maturities therefor specified in such Security or Coupon (or, in the case of redemption, on the Redemption Date or, in the case of repayment pursuant to Article Thirteen hereof at the option of such Holder if provided in or pursuant to this Indenture, on the date such repayment is due) and, in the case of any Security which is convertible into or exchangeable for other securities or property, to convert or exchange, as the case may be, such Security in accordance with its terms, and to institute suit for the enforcement of any such payment and any such right to convert or exchange, and such right shall not be impaired without the consent of such Holder.

Section 509 Restoration of Rights and Remedies.

If the Trustee or any Holder of a Security or a Coupon has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case the Operating Partnership, the Guarantor (if applicable), the Trustee and each such Holder shall, subject to any determination in such proceeding, be restored severally and respectively to their former positions hereunder, and thereafter all rights and remedies of the Trustee and each such Holder shall continue as though no such proceeding had been instituted.

Section 510 Rights and Remedies Cumulative.

To the extent permitted by applicable law and except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities or Coupons in the last paragraph of Section 306, no right or remedy herein conferred upon or reserved to the Trustee or to each and every Holder of a Security or a Coupon is intended to be exclusive of any other right or remedy, and every right and remedy, to the extent permitted by law, shall be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not, to the extent permitted by law, prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 511 Delay or Omission Not Waiver.

No delay or omission of the Trustee or of any Holder of any Security or Coupon to exercise any right or remedy accruing upon any Event of Default shall, to the extent permitted by applicable law, impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the

Trustee or to any Holder of a Security or a Coupon may, to the extent permitted by applicable law, be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by such Xxxxxx, as the case may be.

(2) in the case of any Securities which are convertible into or exchangeable for Common Equity or other securities or property, a continuing default in any such conversion or exchange, or

(3) a continuing default in respect of a covenant or provision hereof which under Article Nine cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series affected.

Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon.

Section 514 Waiver of Usury, Stay or Extension Laws.

Each of the Operating Partnership and the Guarantor covenants that (to the extent that it may lawfully do so) it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury law or any other

Section 515 Undertaking for Costs.

All parties to this Indenture agree, and each Holder of any Security by his acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of any undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and disbursements, against any party litigant in such suit having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section 515 shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in aggregate principal amount of Outstanding Securities of any series, or to any suit instituted by any Holder for the enforcement of the payment of the principal of (or premium, if any) or interest, if any, on or Additional Amounts, if any, with respect to any Security on or after the respective Stated Maturities expressed in such Security (or, in the case of redemption, on or after the Redemption Date, and, in the case of repayment at the option of the Holder pursuant to Article Thirteen hereof, on or after the date for repayment) or for the enforcement of the right, if any, to convert or exchange any Security into Common Equity or other securities or property in accordance with its terms.

ARTICLE SIX

In connection with this Indenture and any Securities issued hereunder, subject to Sections 315(a) through 315(d) of the Trust Indenture Act:

(1) the Trustee may conclusively rely and shall be fully protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, coupon or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties;

(2) any request or direction of the Operating Partnership or the Guarantor mentioned herein shall be sufficiently evidenced by an Operating Partnership Request or

an Operating Partnership Order (in each case, other than delivery of any Security, together with any Coupons appertaining thereto, to the Trustee for authentication and delivery pursuant to Section 303 which shall be sufficiently evidenced as provided therein) and any resolution of the Board of Trustees may be sufficiently evidenced by a Board Resolution;

(3) whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence shall be herein specifically prescribed) may, in the absence of bad faith on its part, conclusively rely upon an Officers’ Certificate;

(4) the Trustee may consult with counsel of its selection and the advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon;

(5) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by or pursuant to this Indenture at the request or direction of any of the Holders of Securities of any series or any Coupons appertaining thereto pursuant to this Indenture, unless such Holders shall have offered to the Trustee reasonable indemnity or security satisfactory to the Trustee against the losses, damages, costs, expenses and liabilities, including reasonable attorneys’ fees, costs and expenses and court costs, which might be incurred by it in compliance with such request or direction;

(6) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, coupon or other paper or document, but the Trustee, in its sole discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, upon reasonable prior written notice and during normal business hours, it shall be entitled to examine the books, records and premises of the Operating Partnership, personally or by agent or attorney and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation;

(7) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder;

(8) the Trustee need perform only those duties that are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee. The Trustee shall not be liable for any action it takes or omits to take in good faith that it believes to be authorized or within its rights or powers. The Trustee is not required to give any bond or surety with respect to the performance of its duties or the exercise of its powers under this Indenture. The permissive right of the Trustee to take the

actions permitted by this Indenture shall not be construed as an obligation or duty to do so;

(9) the Trustee agrees to accept and act upon instructions or directions pursuant to this Indenture sent by unsecured e-mail (PDF only), facsimile transmission or other similar unsecured electronic methods, provided, however, that the Operating Partnership and the Guarantor, respectively, shall provide to the Trustee an incumbency certificate listing designated persons with the authority to provide such instructions, which incumbency certificate shall be amended whenever a person is to be added or deleted from the listing. If the Operating Partnership or the Guarantor elects to give the Trustee e-mail or facsimile transmission instructions (or instructions by a similar electronic method) and the Trustee in its sole and absolute discretion elects to act upon such instructions, the Trustee’s understanding of such instructions shall be deemed controlling. The Trustee shall not be liable for any losses, damages, costs, fees or expenses arising directly or indirectly from the Trustee’s reliance upon and compliance with such instructions notwithstanding such instructions conflict or inconsistency with a subsequent written instruction.

(10) the rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person employed to act hereunder;

(11) in no event shall the Trustee be responsible or liable for special, indirect, punitive or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action; and

Within 90 days after the Trustee has actual knowledge of the occurrence of any default hereunder with respect to the Securities of any series, the Trustee shall transmit by mail to all Holders of Securities of such series, notice of such default hereunder actually known to the Trustee, unless such default shall have been cured or waived; provided, however, that in the case of any default of the character specified in Section 501(3) with respect to Securities of such series, no such notice to Holders shall be given until at least 30 days after the occurrence thereof. For the purpose of this Section, the term “default” means any event which is, or after notice or lapse of time or both would become, an Event of Default with respect to Securities of such series; provided that any default that results solely from the taking of an action that would have been permitted but for the continuation of a previous default will be deemed to be cured if such

previous default is cured prior to becoming an Event of Default. The Trustee shall not be charged with knowledge of any default or Event of Default under this Indenture or related documents unless (i) a Responsible Officer of the Trustee shall have actual knowledge of such Default or Event of Default or (ii) the Trustee shall have received notice in writing of such default or Event of Default by the Operating Partnership or by the Holders of at least 25% in aggregate principal amount of the Securities then Outstanding of the affected series, and such notice is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Securities and this Indenture.

Section 603 Not Responsible for Recitals or Issuance of Securities.

The recitals contained herein and in the Securities, except the Trustee’s certificate of authentication, and in any Coupons shall be taken as the statements of the Operating Partnership or the Guarantor, as the case may be, and neither the Trustee nor any Authenticating Agent assumes any responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Securities, the Guarantee or the Coupons, except that the Trustee represents that it is duly authorized to execute and deliver this Indenture, authenticate the Securities and perform its obligations hereunder and that the statements made by it in a Statement of Eligibility on Form T-1 supplied to the Operating Partnership are true and accurate, subject to the qualifications set forth therein. Neither the Trustee nor any Authenticating Agent shall be accountable for the use or application by the Operating Partnership of the Securities or the proceeds thereof.

Section 604 May Hold Securities; Transactions with the Operating Partnership or the Guarantor.

The Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or any other Person that may be an agent of the Trustee or the Operating Partnership, in its individual or any other capacity, may become the owner or pledgee of Securities or Coupons and, subject to Sections 310(b) and 311 of the Trust Indenture Act, may otherwise deal with the Operating Partnership and the Guarantor with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other Person; provided, however, that if the Trustee acquires any conflicting interest relating to any of its duties with respect to the Securities, it must either eliminate such conflict or resign as Trustee.

Section 605 Money Held in Trust.

The Trustee shall be under no liability for interest on any money received by it hereunder except as otherwise agreed in writing with the Operating Partnership.

Section 606 Compensation and Reimbursement.

The Operating Partnership and, in the event that the Operating Partnership fails to perform the following obligations and indemnities, the Guarantor, agrees:

(2) except as otherwise expressly provided herein, to reimburse the Trustee (acting in any capacity hereunder) upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the expenses and disbursements of its agents and counsel, such as attorneys’ fees, costs and expenses), except any such expense, disbursement or advance as may be attributable to the Trustee’s gross negligence or willful misconduct; and

(3) to indemnify the Trustee (acting in any capacity hereunder), its directors, officers, employees and its agents for, and to hold them harmless against, any loss, claim, cause of action, damage, liability or reasonable cost or expense (including, without limitation, the reasonable fees and disbursements of the Trustee’s agents, legal counsel, accountants and experts), arising out of or in connection with this Indenture or the acceptance or administration of the trust or trusts hereunder, including the reasonable costs and expenses of defending themselves against any claim (whether asserted by the Operating Partnership, the Guarantor, a Holder or any other Person) or liability in connection with the exercise or performance of any of their powers or duties hereunder, except to the extent that any such loss, claim, cause of action, damage, liability or expense was due to the Trustee’s gross negligence or willful misconduct.

The foregoing payment obligations and indemnities shall survive the termination of this Indenture and the resignation or removal of the Trustee.

As security for the performance of the obligations of the Operating Partnership and the Guarantor under this Section, the Trustee shall have a lien prior to the Securities of any series upon all property and funds held or collected by the Trustee as such, except funds held in trust for the payment of principal of, or premium or interest on or any Additional Amounts with respect to Securities or any Coupons appertaining thereto.

Any compensation or expense incurred by the Trustee after a default specified by Section 501(5), (6) or (7) is intended to constitute an expense of administration under any then applicable bankruptcy or insolvency law. “Trustee” for purposes of this Section 606 shall include any predecessor Trustee but the gross negligence or willful misconduct of any Trustee shall not affect the rights of any other Trustee under this Section 606. The provisions of this Section 606 shall, to the extent permitted by law, survive any termination or expiration of this Indenture (including, without limitation, termination pursuant to any bankruptcy or insolvency laws) and the resignation or removal of the Trustee.

Section 607 Corporate Trustee Required; Eligibility.

There shall at all times be a Trustee hereunder that is a Corporation, organized and doing business under the laws of the United States of America, any state thereof or the District of

Columbia, eligible under Section 310(a)(1) of the Trust Indenture Act to act as trustee under an indenture qualified under the Trust Indenture Act and that has a combined capital and surplus (computed in accordance with Section 310(a)(2) of the Trust Indenture Act) of at least $50,000,000 subject to supervision or examination by federal or state authority. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article.

Section 608 Resignation and Removal; Appointment of Successor.

(1) No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee pursuant to Section 609.

(2) The Trustee may resign at any time with respect to the Securities of one or more series by giving written notice thereof to the Operating Partnership. If the instrument of acceptance by a successor Trustee required by Section 609 shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may petition, at the expense of the Operating Partnership, any court of competent jurisdiction for the appointment of a successor Trustee with respect to such series.

(3) The Trustee may be removed at any time with respect to the Securities of any series by Act of the Holders of a majority in aggregate principal amount of the Outstanding Securities of such series, delivered to the Trustee and the Operating Partnership.

If at any time the Operating Partnership shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office.

The Operating Partnership may also from time to time designate co-registrars and one or more offices or agencies where the Securities may be presented or surrendered for any or all such purposes and may from time to time rescind such designations. The Operating Partnership will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

The Operating Partnership hereby initially designates the Trustee as Paying Agent, Security Registrar and Transfer Agent, and the Corporate Trust Office shall be considered as one such office or agency of the Operating Partnership for each of the aforesaid purposes.

So long as the Trustee is the Security Registrar, the Trustee agrees to mail (or send by electronic transmission), or cause to be mailed, the notices set forth in Section 608 and 609 hereof. If co-registrars have been appointed in accordance with this Section 1002, the Trustee

shall mail such notices only to the Operating Partnership and the Holders of Securities it can identify from its records.

Section 1003 Provisions as to Paying Agent.

(1) If the Operating Partnership shall appoint a Paying Agent other than the Trustee, or if the Trustee shall appoint such a Paying Agent, the Operating Partnership will cause such Paying Agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section 1003: (a) that it will hold all sums held by it as such agent for the payment of the principal of and premium, if any, or interest on the Securities (whether such sums have been paid to it by the Operating Partnership or by any other obligor on the Securities) in trust for the benefit of the Holders of the Securities; (b) that it will give the Trustee notice of any failure by the Operating Partnership (or by any other obligor on the Securities) to make any payment of the principal of and premium, if any, or interest on the Securities when the same shall be due and payable; and (c) that at any time during the continuance of an Event of Default, upon request of the Trustee, it will forthwith pay to the Trustee all sums so held in trust.

The Operating Partnership shall, on or before each due date of the principal of, premium, if any, or interest on the Securities, deposit with the Paying Agent a sum (in funds which are immediately available on the due date for such payment) sufficient to pay such principal, premium, if any, or interest and (unless such Paying Agent is the Trustee) the Operating Partnership will promptly notify the Trustee of any failure to take such action; provided, that if such deposit is made on the due date, such deposit shall be received by the Paying Agent by 11:00 a.m. New York City time, on such date.

(2) If the Operating Partnership shall act as its own Paying Agent, it will, on or before each due date of the principal of, premium, if any, or interest on the Securities, set aside, segregate and hold in trust for the benefit of the Holders of the Securities a sum sufficient to pay such principal, premium, if any, and interest so becoming due and will promptly notify the Trustee of any failure to take such action and of any failure by the Operating Partnership (or any other obligor under the Securities) to make any payment of the principal of, premium, if any, or interest on the Securities when the same shall become due and payable.

(3) Anything in this Section 1003 to the contrary notwithstanding, the Operating Partnership may, at any time, for the purpose of obtaining a satisfaction and discharge of this Indenture, or for any other reason, pay or cause to be paid to the Trustee all sums held in trust by the Operating Partnership or any Paying Agent hereunder as required by this Section 1003, such sums to be held by the Trustee upon the trusts herein contained and upon such payment by the Operating Partnership or any Paying Agent to the Trustee, the Operating Partnership or such Paying Agent shall be released from all further liability with respect to such sums.

The Trustee shall not be responsible for the actions of any other Paying Agents (including the Operating Partnership if acting as its own Paying Agent) and shall have no control of any funds held by such other Paying Agents.

Section 1004 Additional Amounts.

In the event that the Operating Partnership is required to make the payment of Additional Amounts to Holders of Securities pursuant to this Indenture, the Operating Partnership will provide written notice (“Additional Amounts Notice”) to the Trustee of its obligation to pay Additional Amounts no later than fifteen (15) calendar days prior to the proposed payment date for Additional Amounts, and the Additional Amount Notice shall set forth the amount of Additional Amounts to be paid by the Operating Partnership on such payment date. The Trustee shall not at any time be under any duty or responsibility to any Holder of Securities to determine the Additional Amounts, or with respect to the nature, extent or calculation of the amount of Additional Amounts when made, or with respect to the method employed in such calculation of the Additional Amounts.

Section 1005 Corporate Existence.

Subject to Article Eight, each of the Operating Partnership and the Guarantor will do or cause to be done all things necessary to preserve and keep in full force and effect its (i) existence, and (ii) rights (charter and statutory) and franchises; provided, that neither the Operating Partnership nor the Guarantor shall be required to preserve any such right or franchise if the Board of Trustees (or any duly authorized committee of that Board of Trustees), as applicable, shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Operating Partnership or the Guarantor, as applicable.

Section 1006 [Reserved]

Section 1007 Waiver of Certain Covenants.

The Operating Partnership and the Guarantor may omit in any particular instance to comply with any term, provision or condition set forth in Sections 1005(ii) with respect to the Securities of any series and, if expressly provided pursuant to Section 301(19), any additional covenants applicable to the Securities of such series if, before the time for such compliance, the Holders of a majority in aggregate principal amount of the Outstanding Securities of such series, by Act of such Holders, either shall waive such compliance in such instance or generally shall have waived compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Operating Partnership and the Guarantor, as applicable and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect.

Section 1008 Operating Partnership and Guarantor Statement as to Compliance.

Within one hundred twenty (120) calendar days after the end of each fiscal year of the Operating Partnership, the Operating Partnership and the Guarantor shall deliver to the Trustee a certificate signed by any of the principal executive officer, principal financial officer or principal

accounting officer of the Operating Partnership and the Guarantor, as the case may be, stating whether or not the signer has knowledge of any default under this Indenture, and, if so, specifying each default and the nature and the status thereof.

The Operating Partnership will deliver to the Trustee, within thirty (30) calendar days of becoming aware of (i) any default in the performance or observance of any covenant, agreement or condition contained in this Indenture, or (ii) any Event of Default, an Officers’ Certificate specifying with particularity such default or Event of Default and further stating what action the Operating Partnership has taken, is taking or proposes to take with respect thereto.

Any notice required to be given under this Section 1008 shall be delivered to a Responsible Officer of the Trustee at its Corporate Trust Office.

Section 1009 Calculation of Original Issue Discount.

So long as there is any Outstanding Original Issue Discount Security, the Operating Partnership shall file with the Trustee promptly at the end of each calendar year (i) a written notice specifying the amount of original issue discount (including daily rates and accrual periods) accrued on Outstanding Securities as of the end of such year and (ii) such other specific information relating to such original issue discount as may then be relevant under the Internal Revenue Code of 1986, as amended from time to time.\

ARTICLE ELEVEN

REDEMPTION OF SECURITIES

Section 1101 Applicability of Article.

Redemption of Securities of any series at the option of the Operating Partnership as permitted or required by the terms of such Securities shall be made in accordance with the terms of such Securities and (except as otherwise provided herein or pursuant hereto) this Article.

Section 1102 Election to Redeem; Notice to Trustee.

The election of the Operating Partnership to redeem any Securities shall be evidenced by or pursuant to a Board Resolution. In case of any redemption at the election of the Operating Partnership of all of the Outstanding Securities of any series, the Operating Partnership shall, not less than 37 and not more than 60 days prior to the Redemption Date fixed by the Operating Partnership, notify the Trustee of such Redemption Date and of the principal amount of Securities of such series to be redeemed and, in the event that the Operating Partnership shall determine that the Securities of any series to be redeemed shall be selected from Securities of such series having the same issue date, interest rate or interest rate formula, Stated Maturity and other terms (the “Equivalent Terms”), the Operating Partnership shall notify the Trustee of such Equivalent Terms.

If less than all of the Securities of any series are to be redeemed or if less than all of the Securities of any series with Equivalent Terms are to be redeemed, the Operating Partnership shall, at least five days prior to giving notice of redemption to the Holders (unless a shorter notice shall be satisfactory to the Trustee and agreed upon in writing by the Trustee), notify the Trustee of such Redemption Date, the principal amount of Securities of such series to be redeemed and, if applicable, the Equivalent Terms.

In the case of any redemption of Securities (A) prior to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture or (B) pursuant to an election of the Operating Partnership which is subject to a condition specified in the terms of such Securities or elsewhere in this Indenture, the Operating Partnership shall furnish to the Trustee an Officers’ Certificate and Opinion of Counsel evidencing compliance with such restriction or condition.

Section 1103 Selection by Trustee of Securities to be Redeemed.

If less than all of the Securities of any series are to be redeemed or if less than all of the Securities of any series with Equivalent Terms are to be redeemed, the particular Securities to be redeemed shall be selected not less than 30 days and not more than 60 days prior to the Redemption Date by the Trustee from the Outstanding Securities of such series or from the Outstanding Securities of such series with Equivalent Terms, as the case may be, not previously called for redemption, by such method as the Trustee shall deem fair and appropriate and in accordance with the Depository’s procedures, and which may provide for the selection for redemption of portions of the principal amount of Registered Securities of such series; provided, however, that no such partial redemption shall reduce the portion of the principal amount of a Security of such series not redeemed to less than the minimum denomination for a Security of such series established herein or pursuant hereto.

The Trustee shall promptly notify the Operating Partnership and the Security Registrar (if other than itself) in writing of the Securities selected for redemption and, in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed.

For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion of the principal of such Securities which has been or is to be redeemed.

Unless otherwise specified in or pursuant to this Indenture or the Securities of any series, if any Security selected for partial redemption is converted or exchanged for Common Equity or other securities or property in part before termination of the conversion or exchange right with respect to the portion of the Security so selected, the converted or exchanged portion of such Security shall be deemed (so far as may be) to be the portion selected for redemption. Securities which have been converted or exchanged during a selection of Securities to be redeemed shall be treated by the Trustee as Outstanding for the purpose of such selection.

Section 1104 Notice of Redemption.

Notice of redemption shall be given in the manner provided in Section 106, not less than 30 nor more than 60 days prior to the Redemption Date, unless a shorter period is specified in the Securities to be redeemed, to the Holders of Securities to be redeemed. Failure to give notice by mailing in the manner herein provided to the Holder of any Registered Securities designated for redemption as a whole or in part, or any defect in the notice to any such Holder, shall not affect the validity of the proceedings for the redemption of any other Securities or portions thereof.

Any notice that is mailed to the Holder of any Registered Securities in the manner herein provided shall be conclusively presumed to have been duly given, whether or not such Holder receives the notice.

All notices of redemption shall state:

(1) the Redemption Date,

(2) the Redemption Price,

(3) if less than all Outstanding Securities of any series are to be redeemed, the identification (and, in the case of partial redemption, the principal amount) of the particular Security or Securities to be redeemed,

(4) that, in case any Security is to be redeemed in part only, on and after the Redemption Date, upon surrender of such Security, the Holder of such Security will receive, without charge, a new Security or Securities of authorized denominations for the principal amount thereof remaining unredeemed,

(5) that, on the Redemption Date, the Redemption Price shall become due and payable upon each such Security or portion thereof to be redeemed, together (if applicable) with accrued and unpaid interest, if any, thereon (subject, if applicable, to the provisos to the first paragraph of Section 1106), and, if applicable, that interest thereon shall cease to accrue on and after said date,

(6) the place or places where such Securities, together (in the case of Bearer Securities) with all Coupons appertaining thereto, if any, maturing after the Redemption Date, are to be surrendered for payment of the Redemption Price and any accrued interest and Additional Amounts pertaining thereto,

(7) that the redemption is for a sinking fund, if such is the case,

(8) that, unless otherwise specified in such notice, Bearer Securities of any series, if any, surrendered for redemption must be accompanied by all Coupons maturing subsequent to the date fixed for redemption or the amount of any such missing Coupon or Coupons will be deducted from the Redemption Price, unless security or indemnity satisfactory to the Operating Partnership, the Trustee and any Paying Agent is furnished,

(9) if Bearer Securities of any series are to be redeemed and any Registered Securities of such series are not to be redeemed, and if such Bearer Securities may be exchanged for Registered Securities not subject to redemption on the Redemption Date pursuant to Section 305 or otherwise, the last date, as determined by the Operating Partnership, on which such exchanges may be made,

(10) in the case of Securities of any series that are convertible or exchangeable into shares of Common Equity or other securities or property, the then current conversion or exchange price or rate, the date or dates on which the right to convert or exchange the principal of the Securities of such series to be redeemed will commence or terminate, as applicable, and the place or places where and the Persons to whom such Securities may be surrendered for conversion or exchange,

(11) the CUSIP number, Common Code or ISIN number of such Securities, if any (or any other numbers used by a Depository to identify such Securities), and

(12) if the Redemption Price or any portion thereof shall be payable, at the option of the Operating Partnership or any Holders, in shares of Common Equity, cash or in other securities or property (or a combination thereof), a statement as to whether the Operating Partnership has elected to pay the Redemption Price in shares of Common Equity, cash or in other securities or property (or a combination thereof) and, if applicable, the portion of the Redemption Price that is to be paid in shares of Common Equity, cash or in other securities or property.

A notice of redemption published as contemplated by Section 106 need not identify particular Registered Securities to be redeemed.

Notice of redemption of Securities to be redeemed at the election of the Operating Partnership shall be given by the Operating Partnership or, at the Operating Partnership’s request with 15 days prior written notice, by the Trustee in the name and at the expense of the Operating Partnership.

Section 1105 Deposit of Redemption Price.

At or prior to 10:00 am (local time in New York City) on any Redemption Date, the Operating Partnership shall deposit, with respect to the Securities of any series called for redemption pursuant to Section 1104, with the Trustee or with a Paying Agent (or, if the Operating Partnership, the Guarantor or any Affiliate of the Operating Partnership or the Guarantor is acting as Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money in the applicable Currency sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date, unless otherwise specified pursuant to Section 301 for or in the Securities of such series) any accrued interest on and Additional Amounts with respect to, all such Securities or portions thereof which are to be redeemed on that date.

Section 1106 Securities Payable on Redemption Date.

Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, together with (unless otherwise provided with respect to the Securities of such series pursuant to Section 301) accrued and unpaid interest, if any, thereon and from and after such date (unless the Operating Partnership shall default in the payment of the Redemption Price and accrued interest, if any) such Securities shall cease to bear interest and the Coupons for such interest appertaining to any Bearer Securities so to be redeemed, except to the extent provided below, shall be void. Upon surrender of any such Security for redemption in accordance with said notice, together with all Coupons, if any, appertaining thereto maturing after the Redemption Date, such Security shall be paid by the Operating Partnership at the Redemption Price, together with, unless otherwise provided in or pursuant to this Indenture, any accrued and unpaid interest thereon and Additional Amounts with respect thereto to but excluding the Redemption Date; provided, however, that, except as otherwise provided in or pursuant to this Indenture or the Bearer Securities of such series, installments of interest on Bearer Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable only upon presentation and surrender of Coupons for such interest (at an Office or Agency located outside the United States except as otherwise provided in Section 1002), and provided, further, that, except as otherwise specified in or pursuant to this Indenture or the Registered Securities of such series, installments of interest on Registered Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the Regular Record Dates therefor according to their terms and the provisions of Section 307.

If any Bearer Security surrendered for redemption shall not be accompanied by all appurtenant Coupons maturing after the Redemption Date, such Security may be paid after deducting from the Redemption Price or, at the option of the Operating Partnership, after payment to the Trustee for the benefit of the Operating Partnership of, an amount equal to the face amount of all such missing Coupons, or the surrender of such missing Coupon or Coupons may be waived by the Operating Partnership and the Trustee if there be furnished to them such security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Security shall surrender to the Trustee or any Paying Agent any such missing Coupon in respect of which a deduction shall have been made from the Redemption Price, such Holder shall be entitled to receive the amount so deducted; provided, however, that any interest or Additional Amounts represented by Coupons shall be payable only upon presentation and surrender of those Coupons at an Office or Agency for such Security located outside of the United States except as otherwise provided in Section 1002.

If any Security called for redemption shall not be so paid, or funds set aside for payment, on the Redemption Date, the principal and any premium, until paid, shall bear interest from the Redemption Date at the rate prescribed therefor in the Security or, if no rate is prescribed therefor in the Security, at the rate of interest, if any, borne by such Security.

Section 1107 Securities Redeemed in Part.

Any Registered Security which is to be redeemed only in part shall be surrendered at any Office or Agency for such Security (with, if the Operating Partnership or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Operating Partnership and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing) and the Operating Partnership shall execute and the Trustee shall authenticate and deliver, upon Operating Partnership Order, to the Holder of such Security without service charge, a new Registered Security or Securities of the same series, containing identical terms and provisions, of any authorized denomination as requested by such Holder in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered. If a Security in global form is so surrendered, the Operating Partnership shall execute, and the Trustee shall authenticate and deliver, upon Operating Partnership Order, to the Depository for such Security in global form as shall be specified in the Operating Partnership Order with respect thereto to the Trustee, without service charge, a new Security in global form in a denomination equal to and in exchange for the unredeemed portion of the principal of the Security in global form so surrendered.

ARTICLE TWELVE

SINKING FUNDS

Section 1201 Applicability of Article.

The provisions of this Article shall be applicable to any sinking fund for the retirement of Securities of a series, except as otherwise permitted or required in or pursuant to this Indenture or any Security of such series issued pursuant to this Indenture.

The minimum amount of any sinking fund payment provided for by the terms of Securities of any series is herein referred to as a “mandatory sinking fund payment,” and any payment in excess of such minimum amount provided for by the terms of Securities of such series is herein referred to as an “optional sinking fund payment.” If provided for by the terms of Securities of any series, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 1202. Each sinking fund payment shall be applied to the redemption of Securities of any series as provided for by the terms of Securities of such series and this Indenture.

Section 1202 Satisfaction of Sinking Fund Payments with Securities.

The Operating Partnership may, in satisfaction of all or any part of any sinking fund payment with respect to the Securities of any series to be made pursuant to the terms of such Securities (1) deliver Outstanding Securities of such series (other than any of such Securities previously called for redemption or any of such Securities in respect of which cash shall have been released to the Operating Partnership), together in the case of any Bearer Securities of such series with all unmatured Coupons appertaining thereto, and (2) apply as a credit Securities of such series which have been redeemed either at the election of the Operating Partnership pursuant to the terms of such series of Securities or through the application of permitted optional

sinking fund payments pursuant to the terms of such Securities, provided that such Securities have not been previously so credited. Such Securities shall be received and credited for such purpose by the Trustee at the Redemption Price specified in such Securities for redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly. If as a result of the delivery or credit of Securities of any series in lieu of cash payments pursuant to this Section 1202, the principal amount of Securities of such series to be redeemed in order to exhaust the aforesaid cash payment shall be less than $100,000, the Trustee need not call Securities of such series for redemption, except upon Operating Partnership Request, and such cash payment shall be held by the Trustee or a Paying Agent and applied to the next succeeding sinking fund payment, provided, however, that the Trustee or such Paying Agent shall at the written request of the Operating Partnership from time to time pay over and deliver to the Operating Partnership any cash payment so being held by the Trustee or such Paying Agent upon delivery by the Operating Partnership to the Trustee of Securities of that series purchased by the Operating Partnership having an unpaid principal amount equal to the cash payment requested to be released to the Operating Partnership.

Section 1203 Redemption of Securities for Sinking Fund.

Not less than 75 days prior to each sinking fund payment date for any series of Securities, the Operating Partnership shall deliver to the Trustee an Officers’ Certificate specifying the amount of the next ensuing mandatory sinking fund payment for that series pursuant to the terms of that series, the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which is to be satisfied by delivering and crediting of Securities of that series pursuant to Section 1202, and the optional amount, if any, to be added in cash to the next ensuing mandatory sinking fund payment, and will also deliver to the Trustee any Securities to be so credited and not theretofore delivered. If such Officers’ Certificate shall specify an optional amount to be added in cash to the next ensuing mandatory sinking fund payment, the Operating Partnership shall thereupon be obligated to pay the amount therein specified. Not less than 60 days before each such sinking fund payment date the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 1103 and cause notice of the redemption thereof to be given in the name of and at the expense of the Operating Partnership in the manner provided in Section 1104. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Sections 1106 and 1107.

ARTICLE THIRTEEN

REPAYMENT AT THE OPTION OF HOLDERS

Section 1301 Applicability of Article.

Securities of any series which are repayable at the option of the Holders thereof before their Stated Maturity shall be repaid in accordance with the terms of the Securities of such series. The repayment of any principal amount of Securities pursuant to such option of the Holder to require repayment of Securities before their Stated Maturity, for purposes of Section 309, shall not operate as a payment, redemption or satisfaction of the indebtedness represented by such Securities unless and until the Operating Partnership, at its option, shall deliver or surrender the

same to the Trustee with a directive that such Securities be cancelled. If specified with respect to the Securities of a series as contemplated by Section 301, in connection with any repayment of Securities, the Operating Partnership may arrange for the purchase of any Securities by an agreement with one or more investment bankers or other purchasers to purchase such Securities by paying to the Holders of such Securities on or before the applicable repayment date an amount not less than the repayment price payable by the Operating Partnership on repayment of such Securities, and the obligation of the Operating Partnership to pay the repayment price of such Securities shall be satisfied and discharged to the extent such payment is so paid by such purchasers.

Unless otherwise expressly stated in this Indenture or pursuant to Section 301 with respect to the Securities of any series or unless the context otherwise requires, all references in this Indenture to the repayment of Securities at the option of the Holders thereof (and all references of like import) shall be deemed to include a reference to the repurchase of Securities at the option of the Holders thereof.

ARTICLE FOURTEEN

SECURITIES IN FOREIGN CURRENCIES

(2) The Trustee shall, by an instrument in writing, appoint a temporary chairman of the meeting, unless the meeting shall have been called by the Operating Partnership, the Guarantor or the Holders of Securities as provided in Section 1502(2), in which case the Operating Partnership, the Guarantor or the Holders of Securities of the series calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the meeting shall be elected by vote of the Persons entitled to vote a majority in aggregate principal amount of the Outstanding Securities of such series represented at the meeting.

(3) At any meeting, each Holder of a Security of such series or proxy shall be entitled to one vote for each $1,000 principal amount of Securities of such series held or represented by him; provided, however, that no vote shall be cast or counted at any meeting in respect of any Security challenged as not Outstanding and ruled by the chairman of the meeting to be not Outstanding. If the Securities of such series are issuable in minimum denominations of less than $1,000, then a Holder of such a Security in a principal amount of less than $1,000 shall be entitled to a fraction of one vote which is equal to the fraction that the principal amount of such Security bears to $1,000. The chairman of the meeting shall have no right to vote, except as a Holder of a Security of such series or proxy.

(4) Any meeting of Holders of Securities of any series duly called pursuant to Section 1502 at which a quorum is present may be adjourned from time to time by Persons entitled to vote a majority in aggregate principal amount of the Outstanding Securities of such series represented at the meeting; and the meeting may be held as so adjourned without further notice.

Section 1506 Counting Votes and Recording Action of Meetings.

The vote upon any resolution submitted to any meeting of Holders of Securities of any series shall be by written ballots on which shall be subscribed the signatures of the Holders of

Securities of such series or of their representatives by proxy and the principal amounts and serial numbers of the Outstanding Securities of such series held or represented by them. The permanent chairman of the meeting shall appoint two inspectors of votes who shall count all votes cast at the meeting for or against any resolution and who shall make and file with the secretary of the meeting their verified written reports in triplicate of all votes cast at the meeting. A record, at least in triplicate, of the proceedings of each meeting of Holders of Securities of any series shall be prepared by the secretary of the meeting and there shall be attached to said record the original reports of the inspectors of votes on any vote by ballot taken thereat and affidavits by one or more persons having knowledge of the facts setting forth a copy of the notice of the meeting and showing that said notice was given as provided in Section 1502 and, if applicable, Section 1504. Each copy shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one such copy shall be delivered to each of the Operating Partnership and the Guarantor, and another to the Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting. Any record so signed and verified shall be conclusive evidence of the matters therein stated.

ARTICLE SIXTEEN

GUARANTEE

Section 1601 Guarantee Agreement; Form of Guarantee

The Guarantor by its execution of this Indenture hereby agrees with each Holder of a Security authenticated and delivered by the Trustee, and with each Holder of any Coupon appertaining to any such Security, and with the Trustee on behalf of such Holder, that the Guarantee in the form set forth below shall apply to such Security:

FORM OF GUARANTEE

This guarantee (this “Guarantee”) dated is entered into by Corporate Office Properties Trust, 0000 Xxxxxxxx Xxxxxxx Xxxxx, Xxxxx 000, Xxxxxxxx, Xxxxxxxx 00000 (the “Guarantor”).

Whereas

(A) Corporate Office Properties, L.P., a Delaware limited partnership (the “Issuer”), is the issuer under an indenture, dated as of (as may be amended or supplemented from time to time, the “Indenture”), among the Issuer, the Guarantor and U.S. Bank National Association, as trustee, which provides for the issuance from time to time of the Issuer’s senior unsecured debentures, notes or other evidences of indebtedness (hereinafter called the “Securities”), unlimited as to principal amount and which will be guaranteed by the Guarantor.

(B) The Guarantor has agreed, under Section 1601 of the Indenture, to issue this Guarantee in respect of all of the Securities issued pursuant to the Indenture to each Holder (as defined in the Indenture) of the Securities.

Now, therefore the Guarantor undertakes as follows:

1. Definitions

Terms defined in or for the purposes of the Indenture and/or the Securities shall have the same meaning in this Guarantee (including the Recitals), except where the context requires otherwise or where a different meaning is attributed to the relevant terms. Any references herein to any amounts payable, howsoever described, in respect of Securities issued by the Issuer shall include any amounts payable by the Issuer under or in connection with the Indenture.

2. Guarantee

The Guarantor, in accordance with the terms hereof, as primary obligor and not merely as a surety, irrespective of the validity and the legal effects of the Securities, irrespective of restrictions of any kind on the Issuer’s performance of its obligations under the Securities, and waiving all rights of objection and defense arising from the Securities, hereby irrevocably and unconditionally guarantees to the Holders, the due and punctual payment of principal, premium (if any), and interest (including any additional amounts required to be paid in accordance with the terms and conditions of the Securities) from time to time payable by the Issuer in respect of the Securities as and when the same shall become due, whether at stated maturity, upon redemption or repurchase, by acceleration or otherwise, and accordingly undertakes to pay such Holder, in the manner and the currency set forth in the terms and conditions of the Securities, any amount or amounts which the Issuer is at any time liable to pay in respect of such Securities and which the Issuer has failed to pay, including amounts that become due in advance of their stated maturity as a result of acceleration. Any diligence, presentment, demand, protest or notice, whether in relation to the Guarantor, the Issuer, or any other person, from a Holder, in respect of any of the Guarantor’s obligations under this Guarantee is hereby waived.

3. Status

The obligations of the Guarantor under this Guarantee constitute direct, unsecured and unsubordinated obligations of the Guarantor and the Guarantor undertakes that its obligations hereunder will rank pari passu with all other present or future direct, unsecured and unsubordinated obligations of the Guarantor, save for such obligations as may be mandatorily preferred by law.

4. Duration

This Guarantee is a guarantee of payment and not merely of collection and it shall continue in full force and effect by way of continuing security until all principal, premium and interest (including any additional amounts required to be paid in accordance with the terms and conditions of the Securities) have been paid in full and all other actual or contingent obligations of the Issuer in relation to the Securities or under the Indenture have been satisfied in full.

Notwithstanding the foregoing, if any payment received by any Holder is, on the subsequent bankruptcy or insolvency of the Issuer, avoided under any applicable laws, including, among others, laws relating to bankruptcy or insolvency, such payment will not be considered as having discharged or diminished the liability of the Guarantor and this Guarantee will continue to apply as if such payment had at all times remained owing by the Issuer.

5. Exercise of Rights, Subrogation and Claims against the Issuer

Until all principal, premium (if any) and interest and all other monies payable by the Issuer in respect of any Securities shall be paid in full, (i) no right of the Guarantor, by reason of the performance of any of its obligations under this Guarantee, to be indemnified by the Issuer or to take the benefit of or enforce any security or other guarantee or indemnity against the Issuer in connection with the Securities shall be exercised or enforced and (ii) the Guarantor shall not (a) by virtue of this Guarantee or any other reason be subrogated to any rights of any Holder or (b) claim in competition with the Holders against the Issuer. If the Guarantor receives any benefit, payment or distribution in relation to such rights it shall hold that benefit, payment or distribution to the extent necessary to enable all amounts which may be or become payable to the Holders by the Issuer under or in connection with the Securities to be paid in full on behalf and for the benefit of the Holders and shall promptly pay or transfer the same to the Holders as they may direct to the extent such amount shall be due and unpaid by the Issuer to the Holders.

6. Notices

Each notice or demand under this Guarantee shall be made in writing, in English, and may be sent by messenger, fax or pre-paid first class post to the Guarantor at the address, and for the attention of the person, from time to time designated by the Guarantor for the purposes of this Guarantee. Any such notice or demand shall be effective when actually received by such addressee. The address, attention and telefax number of the Guarantor for notices or demands under this Guarantee for the time being are as follows:

7. Assignment

The Guarantor shall not be entitled to assign or transfer any or all of its rights, benefits or obligations under this Guarantee. Each Holder shall be entitled to assign all or any of its rights and benefits under this Guarantee.

8. Severability

If a provision of this Guarantee is or becomes illegal, invalid or unenforceable in any jurisdiction, that shall not affect the validity or enforceability in that jurisdiction or in any other jurisdiction of any other provision of this Guarantee.

9. Subsequent Guarantees

Any Securities issued by the Issuer under the Indenture on or after the date of this Guarantee shall have the benefit of this Guarantee, but shall not have the benefit of any subsequent guarantee of the Guarantor, unless expressly so provided in any such subsequent guarantee.

10. Governing Law

This Guarantee shall be governed by, and construed in accordance with, the laws of the State of New York without regard to conflicts of law principles of such State other than New York General Obligations Law Section 5-1401.
