Item 1.01

Entry into a Material Definitive Agreement.

3.875% Exchangeable Guaranteed Notes due 2026

On September 28, 2006, Brandywine Realty Trust, a Maryland real estate investment trust (the “Company”), and its operating partnership, Brandywine Operating Partnership, L.P., a Delaware limited operating partnership (the “Operating Partnership”), entered into a Purchase Agreement (the “Purchase Agreement”) with Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated, Bear, Stearns & Co. Inc. and Lehman Brothers Inc. (the “Initial Purchasers”) providing for the sale by the Operating Partnership and the purchase by the Initial Purchasers of $300 million aggregate principal amount of 3.875% Exchangeable Guaranteed Notes due 2026 (the “Notes”). The Purchase Agreement also granted the Initial Purchasers an option to purchase up to $45 million aggregate principal amount of the Notes to cover over-allotments, if any. The Company has fully and unconditionally guaranteed the payment of principal of and interest on the Notes.

The closing (“Closing”) of the sale of the Notes occurred on October 4, 2006. The net proceeds from the offering, after deducting the Initial Purchasers’ discount and the estimated offering expenses, are estimated to be approximately $293.5 million. The Operating Partnership used approximately $60 million of net proceeds to repurchase 1,829,000 common shares of beneficial interest, par value $0.01 per share, of the Company (the “Common Shares”) at a price of $32.80 per share in a separate, but concurrent, privately negotiated transaction. (After these repurchases, the Company’s previously authorized Common Share repurchase program had approximately 2.3 million of Common Shares available for repurchases.) The Operating Partnership used the approximately $180 million of remaining net proceeds to repay outstanding borrowings under the Operating Partnership’s revolving credit facility and will invest the balance in government or other short-term, rated securities pending the Operating Partnership’s intended redemption of its $300 million Floating Rate Guaranteed Notes due 2009 on January 2, 2007. The Operating Partnership issued the Floating Rate Notes on March 28, 2006.

The Notes were issued under the Indenture, dated as of October 22, 2004, among the Operating Partnership, as Issuer, the Company, as Parent Guarantor, and The Bank of New York, as trustee, (the “Trustee”) as supplemented by the First Supplemental Indenture, dated as of May 25, 2005, among the Operating Partnership, the Company, and the Trustee, as supplemented by the Second Supplemental Indenture (“Second Supplemental Indenture”), dated as of October 4, 2006, among the Operating Partnership, the Company and the Trustee. The terms of the Notes were established pursuant to the Second Supplemental Indenture, a copy of which is filed herewith as Exhibit 4.1. A copy of the form of the Notes is filed herewith as Exhibit 4.2. Additional information pertaining to the Notes is contained in Item 2.03 of this report and is incorporated herein by reference.

The Notes and the Common Shares issuable in certain circumstances upon exchange of the Notes have not been registered under the Securities Act of 1933, as amended (the “Securities Act”). The Company offered and sold the Notes to the Initial Purchasers in reliance on the exemption from registration provided by Section 4(2) of the Securities Act. The Initial Purchasers then sold the Notes to qualified institutional buyers pursuant to the exemption from registration provided by Rule 144A under the Securities Act.

Registration Rights Agreement

At the Closing, the Company and the Operating Partnership entered into a Registration Rights Agreement (the “Registration Rights Agreement”) with the Initial Purchasers. Under the Registration Rights Agreement, the Company and the Operating Partnership have agreed, for the benefit of the holders of the Notes, to file, or have on file, a shelf registration statement providing for the sale by the holders of all of the Notes, and the Common Shares, if any, issuable upon exchange of the Notes (the “Registrable Securities”), within 90 days after the original issuance of the Notes and to use reasonable best efforts to cause such shelf registration statement to be declared effective within 180 days after the original issuance of the Notes or otherwise make available for use by selling security holders an effective shelf registration statement no later than such date. The Company and the Operating Partnership also have agreed to use their respective reasonable best efforts to keep the registration statement effective until such time as all of the Notes and the Common Shares issuable on the exchange thereof cease to be outstanding or have either been (A) sold or otherwise transferred pursuant to an effective registration statement or (B) sold pursuant to Rule 144 under circumstances in which any legend borne by the Notes or Common Shares relating to restrictions on transferability thereof is removed or such Notes or Common Shares are eligible to be sold pursuant to Rule 144(k) or any successor provision, subject to certain exceptions set forth in the Registration Rights Agreement. The Company and the Operating Partnership will be required to pay specified additional interest to the holders of the Notes if they fail to comply with their respective obligations to register the Notes and the Common Shares issuable upon exchange of the Notes within specified time periods, or if the registration statement ceases to be effective or the use of the prospectus is suspended for specified time periods. Neither the Company nor the Operating Partnership will be required to pay additional interest with respect to any Note after it has been exchanged for any Common Shares. A copy of the Registration Rights Agreement is filed herewith as Exhibit 4.3. The description of the Registration Rights Agreement in this report is a summary and is qualified in its entirety by the terms of the Registration Rights Agreement.

Common Share Delivery Agreement

At the Closing, the Company and the Operating Partnership entered into a Common Share Delivery Agreement (the “Common Share Agreement”). The Common Share Agreement, among other things, obligates (i) the Company to deliver Common Shares in the event that the Operating Partnership determines to deliver Common Shares to holders of the Notes upon any exchange of the Notes and (ii) the Operating Partnership to issue to the Company on a concurrent basis a number of its Class A Units equal to such number of Common Shares. A copy of the Common Share Agreement is filed herewith as Exhibit 10.1. The description of the Common Share Agreement in this report is a summary and is qualified in its entirety by the terms of the Common Share Agreement.

(b) Exchange Upon Satisfaction of Trading Price Condition .

(c) Exchange Upon Notice of Redemption . A holder may surrender for exchange any of the Notes called for redemption at any time prior to the close of business on the second business day prior to the redemption date, even if the Notes are not otherwise exchangeable at such time.

Default. Subject to the terms of the Second Supplemental Indenture and the Notes, upon certain events of default, including, but not limited to, (i) failure of the Operating Partnership to deliver cash or Common Shares, or any combination thereof, when due upon an exchange of the Notes, together with any cash due in lieu of fractional shares, and that failure continues for 10 days, and (ii) failure of the Operating Partnership to provide a notice within 20 days of a change in control, the principal and accrued and unpaid interest on the outstanding notes may be declared due and payable.

Section 2.10. Make Whole Amount . If a Change in Control occurs prior to October 20, 2011 as a result of a transaction or event described in clauses (1) or (2) of the definition of Change in Control and a Holder elects to exchange its Notes in connection with such Change in Control pursuant to Section 2.11(d), the Operating Partnership shall increase the applicable Exchange Rate for such Notes surrendered for exchange by a number of additional Company Common Shares (the “ Additional Shares ”) as specified below. An exchange of Notes shall be deemed for these purposes to be “in connection with” such a Change in Control if the notice of exchange of the Notes is received by the Exchange Agent on any date from and including the date that is the Effective Date (as defined below) of such Change in Control up to and including the 30th Business Day following the Effective Date of such Change in Control.

The number of Additional Shares shall be determined by reference to the table below and is based on the date on which such Change in Control transaction becomes effective (the “ Effective Date ”) and the price (the “ Stock Price ”) paid per Company Common Share in such Change in Control transaction. If holders of Company Common Shares receive only cash in a Change in Control transaction described in clause (1) of the definition of such term, the Stock Price shall be the cash amount paid per Company Common Share. In all other cases, the Stock Price shall be the average of the Closing Sale Prices of Company Common Shares on the 10 consecutive Trading Days up to but excluding the Effective Date.

The Stock Prices set forth in the first row of the table (i.e., the column headers) shall be adjusted as of any date on which the Exchange Rate of the Notes is adjusted. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment multiplied by a fraction, the numerator of which is the Exchange Rate immediately prior to the adjustment giving rise to the Stock Price adjustment and the denominator of which is the Exchange Rate as so adjusted. In addition, the number of Additional Shares shall be subject to adjustment in the same manner as the Exchange Rate in accordance with the provisions of Section 2.14 hereof.

The following table sets forth the Stock Price and number of Additional Shares to be received per $1,000 principal amount of Notes:

	Stock Price

Effective Date	$32.80	$40.00	$45.00	$50.00	$55.00	$60.00	$65.00	$70.00

October 4, 2006	5.0813	2.1779	1.1900	0.6388	0.3329	0.1632	0.0681	0.0186
October 15, 2007	5.0813	2.1042	1.0901	0.5437	0.2547	0.1030	0.0270	0.0019

October 15, 2010	5.0813	1.3128	0.3734	0.0459	0.0000	0.0000	0.0000	0.0000
October 20, 2011	5.0813	0.0000	0.0000	0.0000	0.0000	0.0000	0.0000	0.0000

-15-

The actual Stock Prices and Effective Dates may not be set forth in the table, in which case:

(a) if the Stock Price is between two Stock Price amounts in the table or the Effective Date is between two dates in the table, the Additional Shares shall be determined by straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Price amounts and the two dates, as applicable, based on a 365-day year;

(b) if the Stock Price is equal to or in excess of $70.00 per Company Common Share (subject to adjustment as specified in the second preceding paragraph), no Additional Shares shall be issued upon an exchange of Notes;

(c) if the Stock Price is less than $32.80 per Company Common Share (subject to adjustment as specified in the second preceding paragraph), no Additional Shares shall be issued upon an exchange of Notes.

Notwithstanding the foregoing, in no event shall the Exchange Rate (including any Additional Shares) issuable upon an exchange of Notes exceed 30.4878 shares per $1,000 principal amount of Notes, subject to adjustment in the same manner as the Exchange Rate pursuant to Section 2.14 hereof. All calculations under this Section 2.10 shall be the responsibility of the Issuer.

Section 2.11. Exchange Rights .

Subject to the restrictions on ownership of Company Common Shares as set forth in Section 2.15 hereof and to the conditions set forth herein, Holders may surrender their Notes for exchange for cash and Company Common Shares or a combination of cash and Company Common Shares, at the Operating Partnership’s option, at the applicable Exchange Rate prior to the close of business on the second Business Day immediately preceding the Stated Maturity of the Notes either (x) at any time on or after October 15, 2025 or (y) under any of the other circumstances set forth in this Section 2.11.

(a) Exchange Upon Satisfaction of Market Price Condition . A Holder may surrender any of its Notes for exchange during any calendar quarter beginning after December 31, 2006 (and only during such calendar quarter) if, and only if, the Closing Sale Price of Company Common Shares for at least 20 Trading Days (whether or not consecutive) in the period of 30 consecutive Trading Days ending on the last Trading Day of the preceding calendar quarter as determined by the Issuer is more than 130% of the Exchange Price per Company Common Share in effect on the applicable Trading Day. The Board of Trustees of the Company shall make appropriate adjustments, in its good faith determination, to account for any adjustment to the Exchange Rate that becomes effective, or any event requiring an adjustment to the Exchange Rate where the ex-dividend date of the event occurs, during that 30 consecutive trading-day period.

-16-

(b) Exchange Upon Satisfaction of Trading Price Condition . A Holder may surrender any of its Notes for exchange during the five consecutive Trading Day period following any five consecutive Trading Days in which the Trading Price per $1,000 principal amount of Notes (as determined following a reasonable request by a Holder of the Notes) was less than 98% of the product of the Closing Sale Price of Company Common Shares multiplied by the Exchange Rate.

The Trustee shall have no obligation to determine the Trading Price of the Notes unless the Operating Partnership shall have requested such determination, and the Operating Partnership shall have no obligation to make such request unless a Holder provides the Operating Partnership with written reasonable evidence that the Trading Price per $1,000 principal amount of the Notes would be less than 98% of the product of the Closing Sale Price of Company Common Shares and the Exchange Rate, whereupon the Operating Partnership shall instruct the Trustee to determine the Trading Price of the Notes beginning on the next Trading Day and on each successive Trading Day until the Trading Price is greater than or equal to 98% of the product of the Closing Sale Price of Company Common Shares and the Exchange Rate.

(c) Exchange Upon Notice of Redemption . A Holder may surrender for exchange any of the Notes called for redemption at any time prior to the close of business on the second Business Day prior to the Redemption Date, even if the Notes are not otherwise exchangeable at such time. The right to exchange Notes called for redemption pursuant to this clause (c) shall expire after the close of business on the second Business Day prior to the Redemption Date unless the Operating Partnership defaults in making the payment due upon redemption.

(d) Exchange Upon Specified Transactions . If the Company elects to:

(i) distribute to all holders of Company Common Shares rights entitling them to purchase, for a period expiring within 45 days, Company Common Shares at less than the Closing Sale Price of Company Common Shares on the Trading Day immediately preceding the declaration date of the distribution; or

(ii) distribute to all holders of Company Common Shares assets, debt securities or rights to purchase securities of the Operating Partnership or the Company, which distribution has a per share value exceeding 15% of the Closing Sale Price of Company Common Shares on the Trading Day immediately preceding the declaration date of such distribution,

the Operating Partnership shall notify the Holders of the Notes in writing at least 20 days prior to the ex-dividend date for such distribution. Following the giving of such notice, Holders may surrender their Notes for exchange at any time until the earlier of the close of business on the Business Day prior to the ex-dividend date or an announcement that such distribution shall not take place; provided, however , that a Holder may not exercise this right to exchange if the Holder may participate, on an as-exchanged basis, in the distribution without an exchange of Notes. The ex-dividend date is the first date upon which a sale of the Company Common Shares does not automatically transfer the right to receive the relevant distribution from the seller of Company Common Shares to its buyer.

-17-

In addition, if the Operating Partnership or the Company is party to a consolidation, merger, binding share exchange or a sale, lease or other transfer of all or substantially all of the consolidated assets of the Company or the Operating Partnership pursuant to which all of the outstanding Company Common Shares would be exchanged for cash, securities or other property that is not otherwise a Change in Control, a Holder may surrender Notes for exchange at any time from and including the date that is 15 Business Days prior to the anticipated effective time of the transaction up to and including five Business Days after the actual date of such transaction. The Operating Partnership shall notify Holders as promptly as practicable following the date it publicly announces such transaction (but in no event less than 15 Business Days prior to the anticipated effective time of such transaction).

If a Change in Control occurs as a result of a transaction described in clauses (1) or (2) of the definition of “Change in Control”, a Holder shall have the right to exchange its Notes at any time from and including the Effective Date of such transaction up to and including the 30th Business Day following the Effective Date of the transaction, provided that, if a Holder has already delivered an Optional Repurchase Notice or a Change in Control Purchase Notice with respect to a Note, such Holder may not surrender such Note for exchange until it has withdrawn such notice in accordance with the applicable provisions of Section 2.08 or 2.09 hereof, as the case may be. The Operating Partnership shall notify Holders as promptly as practicable following the date that it publicly announces such Change in Control (but in no event later than five Business Days prior to the Effective Date of such Change in Control).

If the Operating Partnership or the Company is a party to a consolidation, merger, binding share exchange or a sale, lease or other transfer of all or substantially all of the consolidated assets of the Company or the Operating Partnership pursuant to which all of the Company Common Shares are exchanged for cash, securities or other property, then from and after the effective time of the transaction, any exchange of Notes, including the Exchange Value and Net Shares deliverable in connection with such exchange, shall be based on, and without limiting the obligation to pay the Principal Return in cash, the Holders shall be entitled to receive for any Net Shares, the kind and amount of cash, securities or other property (the “ Applicable Consideration ”) that the Holder would have received if such Holder had exchanged its Notes for Company Common Shares immediately prior to the effective time of the transaction. For purposes of the foregoing, where a consolidation, merger, binding share exchange or a sale, lease or other transfer of all or substantially all of the consolidated assets of the Company involves a transaction that causes Company Common Shares to be converted into the right to receive more than a single type of consideration based upon any form of shareholder election, the Applicable Consideration shall be deemed to be the weighted average of the types and amounts of consideration received by the holders of Company Common Shares that affirmatively make such an election. At the time of any transaction described in this paragraph, the Operating Partnership or the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the Trust Indenture Act as in force at the date of execution of such supplemental indenture) providing that each Note shall be exchangeable into the Applicable Consideration. Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided in this Second Supplemental Indenture.

-18-

The Operating Partnership shall cause notice of the execution of such supplemental indenture to be mailed to each Holder of Notes, at its address appearing on the Security Register, within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture.

The above provisions shall similarly apply to successive reclassifications, changes, consolidations, mergers, binding share exchanges, combinations, sales and transfers.

If a Change of Control occurs prior to October 20, 2011 as a result of a transaction described in clauses (1) or (2) of the definition thereof, the Operating Partnership shall adjust the Exchange Rate for Notes tendered for exchange in connection with such a Change in Control transaction, as described in Section 2.10 hereof.

(e) Exchange Upon Delisting of Company Common Shares . A Holder of Notes may surrender any of its Notes for exchange at any time beginning on the first Business Day after the Company Common Shares have ceased to be listed on a national or regional securities exchange for a 30 consecutive Trading Day period.

(f) Partial Exchanges and Withdrawal of Purchase Notices . A Holder may exchange fewer than all of its Notes so long as the Notes exchanged are an integral multiple of $1,000 principal amount and the remaining principal amount of Notes is in an authorized denomination. If a Holder has delivered an Optional Repurchase Notice or a Change in Control Purchase Notice with respect to a Note, such Holder may not surrender such Note for exchange until it has withdrawn such notice in accordance with the applicable provisions of Section 2.08 or 2.09 hereof, as the case may be.

Section 2.12. Exchange Settlement . Upon an exchange of Notes, the Operating Partnership shall deliver, in respect of each $1,000 principal amount of Notes tendered for exchange in accordance with their terms:

(a) cash in an amount (the “ Principal Return ”) equal to the lesser of (1) the principal amount of the Notes surrendered for exchange and (2) the Exchange Value, and

(b) if the Exchange Value is greater than the Principal Return, an amount (the “ Net Amount ”) in cash or Company Common Shares with an aggregate value equal to the difference between the Exchange Value and the Principal Return.

The Operating Partnership may elect to deliver any portion of the Net Amount in cash (the “ Net Cash Amount ”) or Company Common Shares, and any portion of the Net Amount the Operating Partnership elects to deliver in Company Common Shares (the “ Net Shares ”) shall be the sum of the Daily Share Amounts for each Trading Day during the Applicable Exchange Period. Prior to the close of business on the second Trading Day following the date on which Notes are tendered for exchange, the Operating Partnership shall inform Holders of such Notes of its election to pay cash for all or a portion of the Net Amount and, if applicable, the portion of the Net Amount that shall be paid in cash and the portion that shall be delivered in the form of Net Shares.

-19-

The Operating Partnership shall deliver cash in lieu of any fractional Company Common Shares issuable in connection with payment of the Net Shares based upon the Average Price.

The “ Daily Share Amount ” for each $1,000 principal amount of Notes and each Trading Day in the Applicable Exchange Period is equal to the greater of:

(a) zero; and

(b) a number of Company Common Shares determined by the following formula:

	(CSP x ER)-($1,000 + the Net Cash Amount, if any)
	10 x CSP

where

CSP means the Closing Sale Price of Company Common Shares on such Trading Day, and

ER means the applicable Exchange Rate

The Operating Partnership shall determine the Exchange Value, Principal Return, Net Amount, Net Cash Amount and the number of Net Shares, as applicable, promptly after the end of the Applicable Exchange Period. The Operating Partnership shall pay the Principal Return and cash in lieu of fractional shares, and deliver Net Shares or pay the Net Cash Amount, or a combination thereof, as applicable, no later than the third Business Day following the last Trading Day of the Applicable Exchange Period.

Section 2.13. Exchange Procedures . To exchange Notes, a Holder must satisfy the requirements set forth in this Section 2.13.

To exchange the Notes, a Holder must (a) complete and manually sign the irrevocable exchange notice on the reverse of the Note (or complete and manually sign a facsimile of such notice) and deliver such notice to the Exchange Agent at the office maintained by the Exchange Agent for such purpose, (b) with respect to Notes which are in certificated form, surrender the Notes to the Exchange Agent, or, if the Notes are in book-entry form, comply with the appropriate procedures of the Depositary, (c) furnish appropriate endorsements and transfer documents if required by the Exchange Agent, the Company or the Trustee and (d) pay any transfer or similar tax, if required. The date on which the Holder satisfies all such requirements shall be deemed to be the date on which the applicable Notes shall have been tendered for exchange.

Notes in respect of which a Holder has delivered an Optional Repurchase Notice or Change in Control Purchase Notice may be exchanged only if such notice is withdrawn in accordance with the terms of Section 2.08 or Section 2.09, as the case may be.

-20-

In case any Note shall be surrendered for partial exchange, the Operating Partnership shall execute and the Trustee shall authenticate and deliver to, or upon the written order of, the Holder of the Note so surrendered, without charge to such holder, a new Note or Notes in authorized denominations in an aggregate principal amount equal to the portion of the surrendered Notes not surrendered for exchange. A Holder may exchange fewer than all of such Holder’s Notes so long as the Notes exchanged are an integral multiple of $1,000 principal amount.

Upon surrender of a Note for exchange by a Holder, such Holder shall deliver to the Operating Partnership cash equal to the amount that the Operating Partnership is required to deduct and withhold under applicable law in connection with the exchange; provided, however , if the Holder does not deliver such cash, the Operating Partnership may deduct and withhold from the amount of consideration otherwise deliverable to such Holder the amount required to be deducted and withheld under applicable law.

Upon exchange of a Note, a Holder shall not receive any cash payment representing accrued and unpaid interest on such Note. Instead, upon an exchange of Notes, the Operating Partnership shall deliver to tendering Holders only the consideration specified in Section 2.12. Delivery of cash and Company Common Shares, if any, upon an exchange of Notes shall be deemed to satisfy the Operating Partnership’s obligation to pay the principal amount of the Notes and any accrued and unpaid interest. Accordingly, upon an exchange of Notes, any accrued and unpaid interest shall be deemed paid in full rather than cancelled, extinguished or forfeited. In no event shall the Exchange Rate be adjusted to account for accrued and unpaid interest on the Notes.

Holders of Notes at the close of business on a Regular Record Date for an interest payment shall receive payment of interest payable on the corresponding Interest Payment Date notwithstanding the exchange of such Notes at any time after the close of business on the applicable Regular Record Date. Notes tendered for exchange by a Holder after the close of business on any Regular Record Date for an interest payment and on or prior to the corresponding Interest Payment Date must be accompanied by payment of an amount equal to the interest that such Holder is to receive on such Notes on such Interest Payment Date; provided, however , that no such payment shall be required to be made (1) if such Notes have been called for redemption on a Redemption Date that is after such Regular Record Date and on or prior to the second Business Day following such Interest Payment Date or (2) with respect to overdue interest (including Additional Interest), if any overdue interest exists at the time of exchange with respect to such Notes.

Upon exchange of a Note, the Operating Partnership, if it elects to deliver Net Shares, shall pay any documentary, stamp or similar issue or transfer tax due on the issue of the Net Shares upon the exchange, if any, unless the tax is due because the Holder requests the shares to be issued or delivered to a person other than the Holder, in which case the Holder must pay the tax due prior to the delivery of such Net Shares. Certificates representing or evidencing Company Common Shares shall not be issued or delivered unless all taxes and duties, if any, payable by the Holder have been paid.

-21-

A Holder of Notes, as such, shall not be entitled to any rights of a holder of Company Common Shares. Such Holder shall only acquire such rights upon the delivery by the Operating Partnership, at its option, of Net Shares in accordance with the provisions of Section 2.12 in connection with the exchange by a Holder of Notes.

If a Holder exchanges more than one Note at the same time, the number of Net Shares, if any, issuable upon the exchange shall be based on the total principal amount of the Notes surrendered for exchange.

The Company shall, prior to issuance of any Notes hereunder, and from time to time as may be necessary, reserve out of its authorized but unissued Company Common Shares a sufficient number of Company Common Shares to permit the exchange of the Notes at the applicable Exchange Rate, assuming an election by the Company to satisfy the entire Net Amount by the delivery of Company Common Shares. Any Company Common Shares delivered upon an exchange of Notes shall be newly issued shares or treasury shares, shall be duly and validly issued and fully paid and nonassessable and shall be free from preemptive rights and free of any lien or adverse claim.

The Company shall endeavor promptly to comply with all federal and state securities laws regulating the issuance and delivery of Company Common Shares, if any, upon an exchange of Notes and, prior to delivering any Company Common Shares upon an exchange of the Notes, shall cause to have listed or quoted all such Company Common Shares on each U.S. national securities exchange or over-the-counter or other domestic market on which the Company Common Shares are then listed or quoted.

Except as set forth herein, no other payment or adjustment for interest shall be made upon exchange of Notes.

Section 2.14. Exchange Rate Adjustments . The Exchange Rate shall be adjusted from time to time as follows:

(a) If the Company issues Company Common Shares as a dividend or distribution on Company Common Shares to all holders of Company Common Shares, or if the Company effects a share split or share combination, the Exchange Rate shall be adjusted based on the following formula:

ER1 =		ER0 x OS1/OS0
where
ER0 =		the Exchange Rate in effect immediately prior to the adjustment relating to such event
ER1 =		the new Exchange Rate in effect taking such event into account
OS0 =		the number of Company Common Shares outstanding immediately prior to such event
OS1 =		the number of Company Common Shares outstanding immediately after such event.

-22-

Any adjustment made pursuant to this paragraph (a) shall become effective on the date that is immediately after (x) the date fixed for the determination of shareholders entitled to receive such dividend or other distribution or (y) the date on which such split or combination becomes effective, as applicable. If any dividend or distribution described in this paragraph (a) is declared but not so paid or made, the new Exchange Rate shall be readjusted to the Exchange Rate that would then be in effect if such dividend or distribution had not been declared.

(b) If the Company issues to all holders of Company Common Shares any rights, warrants, options or other securities entitling them for a period of not more than 45 days after the date of issuance thereof to subscribe for or purchase Company Common Shares, or issues to all holders of Company Common Shares securities convertible into Company Common Shares for a period of not more than 45 days after the date of issuance thereof, in either case at an exercise price per Company Common Share or a conversion price per Company Common Share less than the Closing Sale Price of Company Common Shares on the Business Day immediately preceding the time of announcement of such issuance, the Exchange Rate shall be adjusted based on the following formula:

ER1 =		ER0 x (OS0+X)/(OS0+Y)
where
ER0 =		the Exchange Rate in effect immediately prior to the adjustment relating to such event
ER1 =		the new Exchange Rate taking such event into account
OS0 =		the number of Company Common Shares outstanding immediately prior to such event
X =		the total number of Company Common Shares issuable pursuant to such rights, warrants, options, other securities or convertible securities
Y =		the number of Company Common Shares equal to the quotient of (A) the aggregate price payable to exercise such rights, warrants, options, other securities or convertible securities and (B) the average of the Closing Sale Prices of Company Common Shares for the 10 consecutive Trading Days prior to the Business Day immediately preceding the date of announcement for the issuance of such rights, warrants, options, other securities or convertible securities.

If the application of the foregoing formula would result in a decrease in the Exchange Rate, no adjustment to the Exchange Rate shall be made.

-23-

For purposes of this paragraph (b), in determining whether any rights, warrants, options, other securities or convertible securities entitle the holders to subscribe for or purchase, or exercise a conversion right for, Company Common Shares at less than the applicable Closing Sale Price of Company Common Shares, and in determining the aggregate exercise or conversion price payable for such Company Common Shares, there shall be taken into account any consideration received by the Company for such rights, warrants, options, other securities or convertible securities and any amount payable on exercise or conversion thereof, with the value of such consideration, if other than cash, to be determined by the Board of Trustees of the Company. If any right, warrant, option, other security or convertible security described in this paragraph (b) is not exercised or converted prior to the expiration of the exercisability or convertibility thereof, the new Exchange Rate shall be readjusted to the Exchange Rate that would then be in effect if such right, warrant, option, other security or convertible security had not been so issued.

(c) If the Company distributes shares of capital stock, evidences of indebtedness or other assets or property of the Company to all holders of Company Common Shares, excluding:

(i) dividends, distributions, rights, warrants, options, other securities or convertible securities referred to in paragraph (a) or (b) above,

(ii) dividends or distributions paid exclusively in cash, and

(iii) Spin-Offs described below in this paragraph (c),

then the Exchange Rate shall be adjusted based on the following formula:

ER1 =		ER0 x SP0/(SP0-FMV)
where
ER0 =		the Exchange Rate in effect immediately prior to the adjustment relating to such event
ER1 =		the new Exchange Rate taking such event into account
SP0 =		the average of the Closing Sale Prices of Company Common Shares for the 10 consecutive Trading Days prior to the Business Day immediately preceding the earlier of the record date or the ex-dividend date for such distribution
FMV =		the fair market value (as determined in good faith by the Board of Trustees of the Company) of the shares of capital stock, evidences of indebtedness, assets or property distributed with respect to each outstanding Company Common Share on the earlier of the record date or the ex-dividend date for such distribution.

-24-

An adjustment to the Exchange Rate made pursuant to the immediately preceding paragraph shall be made successively whenever any such distribution is made and shall become effective on the day immediately after the date fixed for the determination of holders of Company Common Shares entitled to receive such distribution.

If the Company distributes to all holders of Company Common Shares, capital stock of any class or series, or similar equity interest, of or relating to a subsidiary or other business unit of the Company (a “ Spin-Off ”), the Exchange Rate in effect immediately before the close of business on the date fixed for determination of holders of Company Common Shares entitled to receive such distribution shall be adjusted based on the following formula:

ER1 =		ER0 x (FMV0+MP0)/MP0
where
ER0 =		the Exchange Rate in effect immediately prior to the adjustment relating to such event
ER1 =		the new Exchange Rate taking such event into account
FMV0 =		the average of the Closing Sale Prices of the capital stock or similar equity interest distributed to holders of Company Common Shares applicable to one Company Common Share over the first 10 consecutive Trading Days after the effective date of the Spin-Off
MP0 =		the average of the Closing Sale Prices of Company Common Shares over the first 10 consecutive Trading Days after the effective date of the Spin-Off.

An adjustment to the Exchange Rate made pursuant to the immediately preceding paragraph shall occur on the 10th Trading Day after the effective date of the Spin-Off.

If any such dividend or distribution described in this paragraph (c) is declared but not paid or made, the new Exchange Rate shall be readjusted to be the Exchange Rate that would then be in effect if such dividend or distribution had not been declared.

-25-

(d) If the Company makes any cash dividend or distribution during any of its quarterly fiscal periods (without regard to when paid) to all holders of Company Common Shares in an aggregate amount that, together with other cash dividends or distributions made in respect of that quarterly fiscal period, exceeds the product of $0.44 (the “ Reference Dividend ”) multiplied by the number of Company Common Shares outstanding on the record date for such distribution, the Exchange Rate shall be adjusted based on the following formula:

ER1 =		ER0 x SP0/(SP0-C)
where
ER0 =		the Exchange Rate in effect immediately prior to the adjustment relating to such event
ER1 =		the new Exchange Rate taking such event into account
SP0 =		the average of the Closing Sale Prices of Company Common Shares for the 10 consecutive Trading Days prior to the business day immediately preceding the earlier of the record date or the day prior to the ex-dividend date for such distribution
C =		the amount in cash per Company Common Share that the Company distributes to holders of Company Common Shares in respect of such quarterly fiscal period that exceeds the Reference Dividend.

An adjustment to the Exchange Rate made pursuant to this paragraph (d) shall become effective on the date immediately after the date fixed for the determination of holders of Company Common Shares entitled to receive such dividend or distribution. If any dividend or distribution described in this paragraph (d) is declared but not so paid or made, the new Exchange Rate shall be readjusted to the Exchange Rate that would then be in effect if such dividend or distribution had not been declared.

Notwithstanding the foregoing, if an adjustment to the Exchange Rate is required to be made as a result of a dividend or distribution that is not a quarterly dividend or distribution either in whole or in part, the Reference Dividend shall be deemed to be zero for purposes of determining the adjustment to the Exchange Rate as a result of such dividend or distribution.

The Reference Dividend shall be subject to adjustment in a manner that is inversely proportional to adjustments to the Exchange Rate; provided that no adjustment shall be made to the Reference Dividend for any adjustment made to the Exchange Rate pursuant to this paragraph (d).

-26-

(e) If the Company or any of its subsidiaries makes a payment in respect of a tender offer or exchange offer for Company Common Shares to the extent that the cash and value of any other consideration included in the payment per Company Common Share exceeds the Closing Sale Price of a Company Common Share on the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer (the “ Expiration Time ”), the Exchange Rate shall be adjusted based on the following formula:

ER1 =		ER0 x (AC + (SP1 x OS1))/(SP1 x OS0)
where
ER0 =		the Exchange Rate in effect immediately prior to the adjustment relating to such event
ER1 =		the new Exchange Rate taking such event into account
AC =		the aggregate value of all cash and any other consideration (as determined by the Board of Trustees of the Company) paid or payable for Company Common Shares purchased in such tender or exchange offer
OS0 =		the number of Company Common Shares outstanding immediately prior to the date such tender or exchange offer expires
OS1 =		the number of Company Common Shares outstanding immediately after such tender or exchange offer expires (after giving effect to the purchase or exchange of shares pursuant to such tender or exchange offer)
SP1 =		the average of the Closing Sale Prices of Company Common Shares for the 10 consecutive Trading Days commencing on the Trading Day next succeeding the date such tender or exchange offer expires.

If the application of the foregoing formula would result in a decrease in the Exchange Rate, no adjustment to the Exchange Rate shall be made.

Any adjustment to the Exchange Rate made pursuant to this paragraph (e) shall become effective on the date immediately following the Expiration Time. If the Company or one of its subsidiaries is obligated to purchase Company Common Shares pursuant to any such tender or exchange offer but is permanently prevented by applicable law from effecting any such purchase or all such purchases are rescinded, the new Exchange Rate shall be readjusted to be the Exchange Rate that would be in effect if such tender or exchange offer had not been made.

(f) Notwithstanding the foregoing, in the event of an adjustment to the Exchange Rate pursuant to paragraph (d) or (e) above, in no event shall the Exchange Rate exceed 30.4878, subject to adjustment pursuant to paragraphs (a), (b) and (c) above.

(g) If the Company has in effect a rights plan while any Notes remain Outstanding, Holders of Notes shall receive, upon an exchange of Notes in respect of which the Operating Partnership has elected to deliver Net Shares, in addition to such Net Shares, rights under the Company’s shareholder rights agreement unless, prior to exchange, the rights have expired, terminated or been redeemed or unless the rights have separated from the Company Common Shares. If the rights provided for in the rights plan adopted by the Company have separated from the Company Common Shares in accordance with the provisions of the applicable shareholder rights agreement so that Holders of Notes would not be entitled to receive any rights in respect of Company Common Shares into which Notes are exchangeable, the Exchange Rate shall be adjusted at the time of separation as if the Company had distributed to all holders of Company Common Shares capital stock, evidences of indebtedness or other assets or property pursuant to paragraph (c) above, subject to readjustment upon the subsequent expiration, termination or redemption of the rights.

-27-

In addition to the adjustments pursuant to paragraphs (a) through (g) above, the Operating Partnership may increase the Exchange Rate in order to avoid or diminish any income tax to holders of Company Common Shares resulting from any dividend or distribution of capital stock (or rights to acquire Company Common Shares) or from any event treated as such for income tax purposes. The Operating Partnership may also, from time to time, to the extent permitted by applicable law, increase the Exchange Rate by any amount for any period if the Operating Partnership has determined that such increase would be in the best interests of the Operating Partnership or the Company. If the Operating Partnership makes such determination, it shall be conclusive and Operating Partnership shall mail to Holders of the Notes a notice of the increased Exchange Rate and the period during which it shall be in effect at least fifteen (15) days prior to the date the increased Exchange Rate takes effect in accordance with applicable law.

If, in connection with any adjustment to the Exchange Rate as set forth in this Section 2.14, a Holder shall be deemed for U.S. federal tax purposes to have received a distribution or other income from the Operating Partnership, the Operating Partnership may set off any withholding tax it or the Company reasonably believes it is required to collect with respect to any such deemed distribution or payment against cash payments of interest in accordance with the provisions of Section 2.05 hereof or from cash and Company Common Shares, if any, otherwise deliverable to a Holder upon an exchange of Notes in accordance with the provisions of Section 2.12 hereof or a redemption or repurchase of a Note in accordance with the provisions of Section 2.07, 2.08 or 2.09 hereof.

The Operating Partnership shall not make any adjustment to the Exchange Rate if Holders of the Notes are permitted to participate, on an as-exchanged basis, in the transactions described above.

Notwithstanding anything to the contrary contained herein, in addition to the other events set forth herein on account of which no adjustment to the Exchange Rate shall be made, the applicable Exchange Rate shall not be adjusted for:

(i) the issuance of any Company Common Shares pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on securities of the Operating Partnership or those of the Company and the investment of additional optional amounts in Company Common Shares under any plan;

(ii) the issuance of any Company Common Shares or options or rights to purchase those shares pursuant to any present or future employee, trustee or consultant benefit plan, employee agreement or arrangement or program of the Operating Partnership or the Company;

(iii) the issuance of any Company Common Shares pursuant to any option, warrant, right, or exercisable, exchangeable or convertible security outstanding as of the date the Notes were first issued;

(iv) a change in the par value of Company Common Shares;

-28-

(v) accumulated and unpaid dividends or distributions;

(vi) as a result of a tender offer solely to holders of less than 100 Company Common Shares; and

(vii) the issuance of limited partnership units by the Operating Partnership and the issuance of Company Common Shares or the payment of cash upon redemption thereof.

No adjustment in the Exchange Rate shall be required unless the adjustment would require an increase or decrease of at least 1% of the Exchange Price. If the adjustment is not made because the adjustment does not change the Exchange Price by at least 1%, then the adjustment that is not made shall be carried forward and taken into account in any future adjustment. All required calculations shall be made to the nearest cent or 1/1000th of a share, as the case may be. Notwithstanding the foregoing, if the Notes are called for redemption, all adjustments not previously made shall be made on the applicable Redemption Date. Except as specifically described above, the applicable Exchange Rate shall not be subject to adjustment in the case of the issuance of any Company Common Shares or Company preferred shares, or securities exchangeable into or exchangeable for Company Common Shares or Company preferred shares.

Whenever the Exchange Rate is adjusted as herein provided, the Company or the Operating Partnership shall as promptly as reasonably practicable file with the Trustee and any Exchange Agent other than the Trustee an Officers’ Certificate setting forth the Exchange Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Promptly after delivery of such certificate, the Company or the Operating Partnership shall prepare a notice of such adjustment of the Exchange Rate setting forth the adjusted Exchange Rate and the date on which each adjustment becomes effective and shall mail such notice of such adjustment of the Exchange Rate to the Holders of the Notes upon request within 20 Business Days of the Effective Date of such adjustment. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

For purposes of this Section 2.14, the number of Company Common Shares at any time outstanding shall not include shares held in the treasury of the Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of Company Common Shares.

Notwithstanding anything in this Section 2.14 to the contrary, in no event shall the Exchange Rate be adjusted so that the Exchange Price would be less than $0.01.

Section 2.15. Ownership Limit; Withholding . Notwithstanding any other provision of the Notes or the instructions contained herein, no Holder of Notes shall be entitled to exchange such Notes for Company Common Shares to the extent that receipt of such shares would cause such Holder (together with such Holder’s affiliates) to exceed the ownership limit contained in the Declaration of Trust of the Company as in effect from time to time.

At the Maturity of the principal of the Notes, whether at Stated Maturity or upon earlier redemption or repurchase of Notes or otherwise, and as otherwise required by law, the Operating Partnership may deduct and withhold from the amount of consideration otherwise deliverable to such Holder the amount required to be deducted and withheld under applicable law.

-29-

Section 2.16. Merger, Consolidation or Sale . Solely for purposes of the Notes, Section 801 of the Indenture is hereby modified and amended to include, in addition to clauses (1), (2) and (3), the following additional clause:

“(4) if as a result of such transaction the Notes become exchangeable into common stock or other securities issued by a third party, such third party shall assume or fully and unconditionally guarantee all obligations under the Notes and the Indenture.”

Section 2.17. Satisfaction and Discharge . The provisions of Sections 401, 402, 403 and 404 of the Indenture shall not be applicable to the Notes. This Indenture shall be discharged and shall cease to be of further effect as to all Notes when either (i) all Notes theretofore authenticated and delivered (except lost, stolen or destroyed Notes which have been replaced or paid as provided in Section 306 of the Indenture) have been delivered to the Trustee for the Notes for cancellation or (ii) (A) all Notes have not theretofore been delivered to the Trustee for cancellation, after the Notes have become due and payable, whether on the date of the Stated Maturity of the principal amount of the Notes, any Redemption Date, Optional Repurchase Date or Change in Control Repurchase Date or upon exchange or otherwise, cash or Company Common Shares in accordance with the terms hereof and the Issuer has irrevocably deposited or caused to be deposited with such Trustee as trust funds in trust an amount of cash in any combination of currency or currency unit in which the Notes are payable (except as otherwise specified pursuant to Section 301 of the Indenture for the Notes) and/or Company Shares sufficient to pay and discharge the entire indebtedness on such Notes for principal (and premium, if any) and accrued and unpaid interest, if any, and pay all other sums payable on the Notes and under the Indenture in respect of such Notes; (B) no Event of Default or event which with the giving of notice or the lapse of time, or both, would become an Event of Default shall have occurred and be continuing on the date of such deposit and no Event of Default under Section 501(5) or Section 501(6) of the Indenture shall have occurred and be continuing on the 123rd day after such date; (C) the Issuer has paid, or caused to be paid, all sums payable by it under the Indenture in respect of the Notes; and (D) the Issuer has delivered irrevocable instructions to the Trustee for the Notes under the Indenture to apply the deposited money toward the payment of such Notes. In addition, the Issuer must deliver an Officers’ Certificate and an Opinion of Counsel to the Trustee for the Notes stating that all conditions precedent to satisfaction and discharge have been satisfied.

-30-

Section 2.18. Events of Default; Waiver of Past Defaults .

(a) Section 501 of the Indenture is modified and amended for purposes of the Notes to add the following Events of Default:

“default in the delivery when due of the Exchange Value, on the terms set forth herein and in the Notes, upon exercise of a Holder’s exchange right in accordance with the terms hereof and of the Notes and the continuation of such default for 10 days;”

– and –

“failure of the Operating Partnership to provide a Company Notice within 20 days after the occurrence of a Change in Control as provided in Section 2.09 of the Second Supplemental Indenture.”

(b) Section 513 of the Indenture is modified and amended for purposes of the Notes to add the following as clause (3):

“(3) in respect of the failure by the Operating Partnership to exchange any Notes in accordance with the provisions of this Indenture.”

Section 2.19. Modification . Section 902 of the Indenture, as modified by this Section 2.19, shall apply solely to the Notes, and Section 902 of the Indenture, other than as modified by this Section 2.19, shall not apply to the Notes. As modified by this Section 2.19 with respect to the Notes, Section 902 of the Indenture is as follows:

“With the consent of the Holders of a majority in principal amount of all Outstanding Notes affected by such supplemental indenture (voting together as a single class), by Act of said Holders delivered to the Issuer, the Parent Guarantor and the Trustee, the Issuer, when authorized by or pursuant to a Board Resolution, the Parent Guarantor (when authorized by or pursuant to a Parent Guarantor’s Board Resolution), and the Trustee may enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of modifying in any manner the rights of the Holders of Notes under this Indenture; provided, however, that no such supplemental indenture shall, without the consent of the Holder of each Outstanding Note affected thereby:

(a) change the Stated Maturity of the principal of, or any installment interest (including Additional Interest, if any) on, the Notes;

(b) reduce the principal amount of, the rate of interest (including Additional Interest, if any) on, or change the timing or reduce the amount payable on the redemption of, the Notes;

(d) change the Place of Payment, or the coin or currency, for payment of principal of, or interest (including Additional Interest, if any) on, the Notes;

(e) impair the right to institute suit for the enforcement of any payment on or with respect to Notes or the delivery of the Exchange Value as required by the Indenture upon an exchange of Notes;

Until the expiration of the holding period applicable to sales of Restricted Securities under Rule 144(k) under the Securities Act (or any successor provision), any certificate evidencing a Restricted Security shall bear a legend in substantially the following form, unless such Restricted Security has been sold pursuant to a registration statement that has been declared effective under the Securities Act (and which continues to be effective at the time of such transfer) or sold pursuant to Rule 144 under the Securities Act or any similar provision then in force, or unless otherwise agreed by the Issuer in writing, with written notice thereof to the Trustee:

THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE SECURITIES LAWS, AND MAY NOT BE OFFERED OR SOLD EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF, THE HOLDER:

(1) REPRESENTS THAT IT IS A “QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IS AWARE THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A UNDER THE SECURITIES ACT AND IS PURCHASING THIS SECURITY IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT;

-33-

(3) AGREES THAT IT SHALL DELIVER TO EACH PERSON TO WHOM THIS SECURITY IS TRANSFERRED (OTHER THAN A TRANSFER PURSUANT TO CLAUSE 2(C) OR 2(D) ABOVE) A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. IN CONNECTION WITH ANY TRANSFER OF THIS SECURITY WITHIN TWO YEARS AFTER THE LATER OF THE ORIGINAL ISSUE DATE OF THIS SECURITY AND THE LAST DATE ON WHICH THE ISSUER OR THE COMPANY OR AN AFFILIATE THEREOF WAS THE OWNER OF THIS SECURITY, THE HOLDER MUST CHECK THE APPROPRIATE BOX SET FORTH ON THE REVERSE HEREOF RELATING TO THE MANNER OF SUCH TRANSFER AND SUBMIT THIS SECURITY TO THE TRUSTEE (OR ANY SUCCESSOR TRUSTEE, AS APPLICABLE). IF THE PROPOSED TRANSFER IS PURSUANT TO CLAUSE 2(C) ABOVE, THE HOLDER MUST, PRIOR TO SUCH TRANSFER, FURNISH TO THE TRUSTEE (OR ANY SUCCESSOR TRUSTEE, AS APPLICABLE), SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS THE COMPANY, THE ISSUER OR THE TRUSTEE MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

If such Restricted Security surrendered for exchange is represented by a global Note bearing the legend set forth in this Section 2.25(a), the principal amount of the legended global Note shall be reduced by the appropriate principal amount and the principal amount of a global Note without the legend set forth in this Section 2.25(a) shall be increased by an equal principal amount. If a global Note without the legend set forth in this Section 2.25(a) is not then outstanding, the Issuer shall execute and the Trustee shall authenticate and deliver an unlegended global Note to the Depositary.

In the event Rule 144(k) under the Securities Act (or any successor provision) is amended to shorten the two-year period under Rule 144(k), then, the references in the restrictive legends set forth above to “TWO YEARS,” and in the corresponding transfer restrictions described above, and in the Notes and the Company Common Shares shall be deemed to refer to such shorter period, from and after receipt by the Trustee of an Officers’ Certificate and an Opinion of Counsel to that effect. As soon as reasonably practicable after the Issuer knows of the effectiveness of any such amendment to shorten the two-year period under Rule 144(k), unless such changes would otherwise be prohibited by, or would cause a violation of, the federal securities laws applicable at the time, the Issuer shall provide to the Trustee an Officers’ Certificate and an Opinion of Counsel as to the effectiveness of such amendment and the effectiveness of such change to the restrictive legends and transfer restrictions.

(a) Any Restricted Securities, prior to the expiration of the holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any successor provision), purchased or owned by the Issuer or any Affiliate thereof may not be resold by the Issuer or such Affiliate and shall be surrendered to the Trustee for cancellation.

(b) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this instrument or under applicable law with respect to any transfer of any interest in any Note other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this instrument, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

If either the Issuer or the Parent Guarantor is not required to file the foregoing forms or reports with the commission, then it shall file with the Trustee and the Commission such reports as may be prescribed by the Commission at such time.

The Trustee shall not at any time be under any duty or responsibility to any Holder of Notes to determine the Additional Interest, or with respect to the nature, extent or calculation of the amount of Additional Interest when made, or with respect to the method employed in such calculation of the Additional Interest.

If the Shelf Registration Statement is not an Automatic Shelf Registration Statement, the Company and the Operating Partnership shall use their respective reasonable best efforts to have such Shelf Registration Statement declared effective by the SEC as promptly as practicable after filing thereof, but in any event on or prior to the Effectiveness Deadline. If the Shelf Registration Statement is an Automatic Shelf Registration Statement, the Company and the Operating Partnership shall use their respective reasonable best efforts to prepare and file a supplement to the Prospectus to cover resales of the Registrable Securities by the Holders as promptly as practicable after filing thereof, but in any event on or prior to the Effectiveness Deadline.

(ii) Notwithstanding any other provision hereof, no Holder of Registrable Securities shall be entitled to include any of its Registrable Securities in any Shelf Registration Statement pursuant to this Agreement unless and until such Holder agrees in writing to be bound by all of the provisions of this Agreement applicable to such Holder and the Holder furnishes to the Company and the Operating Partnership a fully completed notice and questionnaire in the form attached as Appendix A to the Offering Memorandum (the “ Questionnaire ”) and such other information in writing as the Company and the Operating Partnership may reasonably request in writing for use in connection with the Shelf Registration Statement or Prospectus included therein and in any application to be filed with or under state securities laws. The Company and the Operating Partnership shall issue a press release through a reputable national newswire service of their filing (or intention to designate an Automatic Shelf Registration Statement as) the Shelf Registration Statement and of the anticipated Effective Date thereof. In order to be named as a selling securityholder in the Prospectus at the time it is first made available for use, each Holder must furnish the completed Questionnaire and such other information that the Company and the Operating Partnership may reasonably request in writing, if any, to the Company and the Operating Partnership in writing no later than the tenth Business Day prior to the anticipated Effective Date as announced in the press release. Each Holder as to which any Shelf Registration is being effected agrees to furnish to the Company and the Operating Partnership all information with respect to such Holder necessary to make the information previously furnished to the Company and the Operating Partnership by such Holder not materially misleading.

(iii) From and after the Effective Date, upon receipt of a completed Questionnaire and such other information that the Company and the Operating Partnership may reasonably request in writing, if any, the Company and the Operating Partnership will use their respective reasonable best efforts to file as promptly as reasonably practicable but in any event on or prior to the Filing Deadline either (i) if then permitted by the Securities Act or the rules and regulations thereunder (or then-current SEC interpretations thereof), a supplement to the Prospectus naming such Holder as a selling securityholder and containing such other information as necessary to permit such Holder to deliver the Prospectus to purchasers of the Holder’s Securities, or (ii) if it is not then permitted under the Securities Act or the rules and regulations thereunder (or then-current SEC interpretations thereof) to name such Holder as a selling securityholder in a supplement to the Prospectus, a post-effective amendment to the Shelf Registration Statement or an additional Shelf Registration Statement as necessary for such Holder to be named as a selling securityholder in the Prospectus contained therein to permit such Holder to deliver the Prospectus to purchasers of the Holder’s Securities (subject, in the case of either clause (i) or (ii), to the Company’s and the Operating Partnership’s right to suspend use of the Shelf Registration Statement as described in Section 2(a)(iv) hereof). If a post-effective amendment or additional Shelf Registration Statement is required to be filed, the Company and the Operating Partnership shall use their respective reasonable best efforts to have such post-effective amendment or additional Shelf Registration Statement declared effective by the SEC as promptly as practicable after filing thereof, but in any event on or prior to the Effectiveness Deadline. The Company and the Operating Partnership shall not be required to file more than three supplements to the Prospectus, post-effective amendments or additional Shelf Registration Statements in any fiscal quarter for all such Holders.

-5-

(iv) Each of the Company and the Operating Partnership agrees to use its reasonable best efforts to keep the Shelf Registration Statement continuously effective and the Prospectus usable for resales until there are no Registrable Securities outstanding (the “ Effectiveness Period ”); provided, however , that for 30 days or less (whether or not consecutive) in any three-month period, and for 90 days or less in any 12-month period, the Company and the Operating Partnership shall be permitted, by giving written notice to the Holders of Registrable Securities, to suspend sales thereof if the Shelf Registration Statement is no longer effective or usable for resales due to circumstances relating to pending developments, public filings with the SEC and similar events, or because the Prospectus contains an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary in order to make statements therein not misleading (any period of suspension hereunder, a “ Suspension Period ”). If any Shelf Registration Statement ceases to be effective or usable for resales by Holders for any reason (other than by reason of any such Holder’s failure to provide a Questionnaire, in which case the provisions of Section 2(a)(ii) or 2(a)(iii) hereof shall apply) at any time during the Effectiveness Period, the Operating Partnership and the Company shall, subject to the proviso contained in the immediately preceding sentence, use their respective reasonable best efforts to promptly cause such Shelf Registration Statement to become effective under the Securities Act, and in any event shall, within ten Business Days of such cessation of effectiveness or usability, (i) file with the SEC one or more supplements to the Prospectus, post-effective amendments or reports under the Exchange Act in a manner reasonably expected to obtain the withdrawal of any order suspending the effectiveness of such Shelf Registration Statement, or (ii) file with the SEC an additional Shelf Registration Statement. If a post-effective amendment or an additional Shelf Registration Statement is filed, the Operating Partnership and the Company shall use their respective reasonable best efforts to (A) cause such post-effective amendment or Shelf Registration Statement to become effective under the Securities Act as promptly as practicable after such filing, but in no event later than the applicable Effectiveness Deadline, and (B) keep such post-effective amendment or Shelf Registration Statement continuously effective until the end of the Effectiveness Period.

(v) If the Shelf Registration Statement is not an Automatic Shelf Registration Statement, the Company and the Operating Partnership shall not permit any securities other than (i) the Company’s and the Operating Partnership’s issued and outstanding securities currently possessing incidental or so-called “piggy-back” registration rights and (ii) the Registrable Securities to be included in the Shelf Registration. The Company and the Operating Partnership will provide to each Holder named therein a reasonable number of copies of the Prospectus which is a part of the Shelf Registration Statement, notify each such Holder of the Effective Date and take such other actions as are required to permit unrestricted resales of the Registrable Securities by such Holder. Each of the Company and the Operating Partnership further agrees to supplement or amend the Shelf Registration Statement or supplement the Prospectus if and as required by the rules, regulations or instructions applicable to the registration form used by the Company and the Operating Partnership for such Shelf Registration Statement or by the Securities Act or by any other rules and regulations thereunder for shelf registrations, and each of the Company and the Operating Partnership agrees to furnish to the Holders of Registrable Securities copies of any such supplement or amendment promptly after its being used or filed with the SEC.

-6-

(b) Listing. The Company shall use its reasonable best efforts to maintain the approval of the Common Shares for listing on the New York Stock Exchange during the Effectiveness Period.

(c) Expenses. The Company and the Operating Partnership shall, jointly and severally, pay all Registration Expenses in connection with any Shelf Registration Statement filed pursuant to Section 2(a) hereof (including the reasonable fees and disbursements of one counsel for the Holders of the Registrable Securities in connection with the review of any Shelf Registration Statement, Prospectus or amendment or supplement thereto in accordance with the provisions of Section 3(a) hereof, which counsel shall be reasonably satisfactory to the Company and the Operating Partnership). Except as provided herein, each Holder shall pay all expenses of its counsel, underwriting discounts and commissions and transfer taxes, if any, relating to the sale or disposition of such Holder’s Registrable Securities pursuant to the Shelf Registration Statement.

(d) Effective Shelf Registration Statement. If, after the Effective Date the offering of Registrable Securities pursuant to a Shelf Registration Statement is interfered with by any stop order, injunction or other order or requirement of the SEC or any other governmental agency or court, such Shelf Registration Statement will be deemed not to have been effective during the period of such interference, until the offering of Registrable Securities pursuant to such Shelf Registration Statement may legally resume. Each of the Company and the Operating Partnership will be deemed not to have used its reasonable best efforts to cause a Shelf Registration Statement to become, or to remain, effective during the requisite period if it voluntarily takes any action that knowingly would result in any such Shelf Registration Statement not being declared effective or that knowingly would result in the Holders of Registrable Securities covered thereby not being able to offer and sell such Registrable Securities during that period, unless such action is required by applicable law.

(e) Additional Interest. In the event that:

(i) a Shelf Registration Statement is not filed with the SEC or designated as such by the Company and the Operating Partnership on or prior to the Filing Deadline pursuant to Section 2(a)(i), then additional interest (“ Additional Interest ”) shall accrue on the principal amount of the Securities at a rate equal to 0.25% per year for the first 90-day period from the day following such Filing Deadline, and thereafter at a rate per year of 0.50% of the principal amount of the Securities;

-7-

(ii) (x) a Shelf Registration Statement is not declared effective by the SEC, or (y) if the Company and the Operating Partnership shall have designated a previously filed and effective Automatic Shelf Registration Statement as the Shelf Registration Statement for purposes of this Agreement, the Company and the Operating Partnership shall not have filed a supplement to the Prospectus to cover resales of the Registrable Securities by the Holders, in the case of either (x) or (y), on or prior to the Effectiveness Deadline pursuant to Section 2(a)(i), then Additional Interest shall accrue on the principal amount of the Securities at a rate equal to 0.25% per year for the first 90-day period from the day following such Effectiveness Deadline, and thereafter at a rate per year of 0.50% of the principal amount of the Securities;

(iii) following the Effective Date, (A) the Company and the Operating Partnership fail to make any filing required pursuant to Section 2(a)(iii) hereof prior to the Filing Deadline applicable thereto, or (B) in the event such filing is a post-effective amendment or additional Shelf Registration Statement, such post-effective amendment or Shelf Registration Statement fails to become effective on or prior to the Effectiveness Deadline applicable thereto, then Additional Interest shall accrue on the principal amount of the Securities at a rate equal to 0.25% per year for the first 90-day period from the day following such Filing Deadline or Effectiveness Deadline, as applicable, and thereafter at a rate per year of 0.50% of the principal amount of the Securities;

(iv) following the Effective Date, a Shelf Registration Statement ceases to be effective (without being succeeded immediately by an additional Shelf Registration Statement that is filed and immediately becomes effective) or usable for the offer and sale of the Registrable Securities, other than in connection with (A) a Suspension Period or (B) as a result of a requirement to file a post-effective amendment or supplement to the Prospectus to make changes to the information regarding selling securityholders or the plan of distribution provided for therein, and the Company and the Operating Partnership do not cure the lapse of effectiveness or usability within ten Business Days (or, if a Suspension Period is then in effect, within ten Business Days following the expiration of such Suspension Period), then Additional Interest shall accrue on the principal amount of the Securities at a rate equal to 0.25% per year for the first 90-day period from the day following such tenth Business Day, and thereafter at a rate per year of 0.50% of the principal amount of the Securities;

(v) any Suspension Period or Periods exceed 30 days in any three-month period or 90 days in any 12-month period, then, commencing with the 31st day in such three-month period or the 91st day in such 12-month period, as the case may be, then Additional Interest shall accrue on the principal amount of the Securities at a rate equal to 0.25% per year for the first 90-day period from the day following the 31st or 91st day, as the case may be, and thereafter at a rate per year of 0.50% of the principal amount of the Securities; or

(vi) if the Company and the Operating Partnership fail to name as a selling securityholder any Holder that had complied timely with its obligations hereunder in a manner to entitle such Holder to be so named in (A) any Shelf Registration Statement at the time it first becomes effective or (B) any Prospectus at the later of time of filing thereof or the time the Shelf Registration Statement of which the Prospectus forms a part becomes effective, then Additional Interest will accrue on the principal amount of Securities held by such Holder at a rate equal to 0.25% per year for the first 90-day period from the day following the effective date of such Shelf Registration Statement or the time of filing of such Prospectus, as the case may be, and thereafter at a rate per year of 0.50% of the principal amount of the Securities held by such Holder;

-8-

provided, however , that in no event shall Additional Interest accrue at a rate per year exceeding 0.50% of the principal amount of the Securities; and provided, further , that Additional Interest on the principal amount of the Securities as a result thereof shall cease to accrue:

(1) upon the filing or designation of a Shelf Registration Statement (in the case of clause (i) above);

(2) upon the Effective Date (in the case of clause (ii) above);

(3) upon the filing of a supplement to the Prospectus (in the case of clause (iii)(A) above) or upon the Effective Date (in the case of clause (iii)(B) above);

(4) upon such time as the Shelf Registration Statement which had ceased to remain effective or usable for resales again becomes effective and usable for resales (in the case of clause (iv) above);

(5) upon such time as the Shelf Registration Statement which had ceased to remain effective or usable for resales again becomes effective and usable for resales (in the case of clause (v) above); or

(6) upon the time such Holder is permitted to sell its Registrable Securities pursuant to any Shelf Registration Statement and Prospectus in accordance with applicable law (in the case of clause (vi) above).

Any amounts of Additional Interest due pursuant to Section 2(e) will be payable semi-annually in arrears in cash on the next succeeding interest payment date to Holders entitled to receive such Additional Interest on the relevant record dates for the payment of interest.

Notwithstanding any provision in this Agreement, in no event shall Additional Interest accrue to holders of Common Shares issued upon exchange of Notes. If any Note ceases to be outstanding during any period for which Additional Interest are accruing, the Company and the Operating Partnership will prorate the Additional Interest payable with respect to such Note. Additional Interest shall represent the sole entitlement of the Holders to money damages relating to the failure of the Company to file or otherwise designate a Shelf Registration Statement with the SEC on or prior to the Filing Deadline.

(f) Specific Enforcement. Without limiting the remedies available to the Holders, each of the Company and the Operating Partnership acknowledges that any failure by it to comply with its obligations under Section 2(a) hereof may result in material irreparable injury to the Holders for which there is no adequate remedy at law, that it would not be possible to measure damages for such injuries precisely and that, in the event of any such failure, any Holder may obtain such relief as may be required to specifically enforce the Company’s and the Operating Partnership’s obligations under Section 2(a) hereof.

(l) make reasonably available for inspection by any selling Holder of Registrable Securities who certifies to the Company and the Operating Partnership that it has a current intention to sell Registrable Securities pursuant to the Shelf Registration, any underwriter participating in any such disposition of Registrable Securities, and any attorney, accountant or other agent retained by any such selling Holder or underwriter (collectively, the “ Inspectors ”), at the offices where normally kept, during the Company’s and the Operating Partnership’s normal business hours, all financial and other records, pertinent organizational and operational documents and properties of the Company, the Operating Partnership and their respective subsidiaries (collectively, the “ Records ”) as shall be reasonably necessary to enable them to exercise any applicable due diligence responsibilities, and cause the officers, trustees and employees of the Company and its subsidiaries to supply all relevant information in each case reasonably requested by any such Inspector in connection with such Shelf Registration Statement; provided that (x) Records and information which the Company and the Operating Partnership, in good faith, determine to be confidential and any Records and information which either the Company or the Operating Partnership notifies the Inspectors are confidential shall not be disclosed to any Inspector except where (i) the disclosure of such Records or information is necessary to avoid or correct a material misstatement or omission in such Shelf Registration Statement, (ii) the release of such Records or information is ordered pursuant to a subpoena or other order from a court of competent jurisdiction or is necessary in connection with any action, suit or proceeding or (iii) such Records or information previously have been made generally available to the public; (y) each selling Holder of such Registrable Securities will be required to agree in writing that Records and information obtained by it as a result of such inspections shall be deemed confidential and shall not be used by it as the basis for any market transactions in the securities of the Company or the Operating Partnership unless and until such Records or information are made generally available to the public through no fault of an Inspector or a selling Holder; and (z) each selling Holder of such Registrable Securities will be required to further agree in writing that it will, upon learning that disclosure of such Records or information is sought in a court of competent jurisdiction, or in connection with any action, suit or proceeding, give notice, to the extent permitted by applicable law, to the Company and the Operating Partnership and allow the Company and the Operating Partnership at their expense to undertake appropriate action to prevent disclosure of the Records and information deemed confidential;

-13-

(n) cooperate with each seller of Registrable Securities covered by a Shelf Registration Statement and each underwriter, if any, participating in the disposition of such Registrable Securities and their counsel in connection with any filings required to be made with the NASD;

(o) take all other steps necessary to effect the registration of the Registrable Securities covered by a Shelf Registration Statement contemplated hereby; and

(p) the Company and the Operating Partnership may require each seller of Registrable Securities as to which any registration is being effected to furnish to it such information regarding such seller as may be required by the staff of the SEC to be included in a Shelf Registration Statement; the Company and the Operating Partnership may exclude from such registration the Registrable Securities of any seller who unreasonably fails to furnish such information within a reasonable time after receiving such request; and the Company and the Operating Partnership shall have no obligation to register under the Securities Act the Registrable Securities of a seller who so fails to furnish such information.

Each Holder agrees that, upon receipt of any notice from the Company or the Operating Partnership of the occurrence of any event specified in Section 3(e)(ii), 3(e)(iii), 3(e)(v) or 3(e)(vi) hereof, such Holder will forthwith discontinue disposition of Registrable Securities pursuant to a Shelf Registration Statement until such Holder’s receipt of the copies of the supplemented or amended Prospectus contemplated by Section 3(i) hereof or until it is advised in writing (the “ Advice ”) by the Company or the Operating Partnership that the use of the applicable Prospectus may be resumed, and, if so directed by the Company or the Operating Partnership, such Holder will deliver to the Company or the Operating Partnership (at its expense) all copies in such Holder’s possession, other than permanent file copies then in such Holder’s possession, of the Prospectus covering such Registrable Securities current at the time of receipt of such notice. If the Company or the Operating Partnership shall give any such notice to suspend the disposition of Registrable Securities pursuant to a Shelf Registration Statement, each of the Company and the Operating Partnership shall use its reasonable best efforts to file and have declared effective (if an amendment) as soon as practicable after the resolution of the related matters an amendment or supplement to the Shelf Registration Statement and related Prospectus.

-14-

4. Indemnification and Contribution. (a) The Company and the Operating Partnership hereby agree, jointly and severally, to indemnify and hold harmless the Initial Purchasers, each Holder, each underwriter who participates in an offering of the Registrable Securities, each Person, if any, who controls any of such parties within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act and each of their respective directors, officers, employees and agents, as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of (x) any untrue statement or alleged untrue statement of a material fact contained in a Shelf Registration Statement (or any amendment thereto) or the omission or alleged omission from the Shelf Registration Statement (or any amendment thereto) of a material fact which is required to be stated therein or which is necessary in order to make the statements therein not misleading, or (y) any untrue statement or alleged untrue statement of a material fact contained in the Prospectus (or any amendment or supplement thereto) or the omission or alleged omission from the Prospectus (or any amendment or supplement thereto) of a material fact which is required to be stated therein or which is necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, provided that (subject to Section 4(d) hereof) such settlement is effected with the prior written consent of the Company and the Operating Partnership; and

(iii) against any and all expenses whatsoever, as incurred (including the reasonable fees and disbursements of counsel chosen by the Initial Purchasers or such Holder), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under subparagraph (i) or (ii) of this Section 4(a); provided, however , that this indemnity does not apply to any loss, liability, claim, damage or expense to the extent arising out of an untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished in writing to the Company or the Operating Partnership by any Initial Purchaser through the Representative or such Holder or underwriter for use in the Shelf Registration Statement (or any amendment thereto) or any Prospectus (or any amendment or supplement thereto).

-15-

(b) Each Holder and each underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its trustees and officers (including each officer of the Company who signed the Shelf Registration Statement), the Operating Partnership and its partners, the Initial Purchasers, and each Person, if any, who controls the Company or the Operating Partnership or any Initial Purchaser within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act against any and all loss, liability, claim, damage and expense whatsoever described in the indemnity contained in Section 4(a) hereof, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Shelf Registration Statement (or any amendment thereto) or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Company or the Operating Partnership by such Holder expressly for use in such Shelf Registration Statement (or any amendment thereto) or such Prospectus (or any amendment or supplement thereto); provided, however , that no Holder shall be liable for any claims hereunder in excess of the amount of net proceeds received by such Holder from the sale of Registrable Securities.

(c) Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability which it may have under this Section 4 to the extent that it is not materially prejudiced by such failure as a result thereof, and in any event shall not relieve it from liability which it may have otherwise on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 4(a) or (b) above, counsel to the indemnified parties shall be selected by such parties. An indemnifying party may participate at its own expense in the defense of such action; provided, however , that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for the fees and expenses of more than one counsel (in addition to local counsel), separate from their own counsel, for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 4 (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional written release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) If at any time an indemnified party shall have validly requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 4(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

-16-

(e) In order to provide for just and equitable contribution in circumstances in which the indemnity agreement set forth in this Section 4 is for any reason held to be unenforceable by an indemnified party although applicable in accordance with its terms, the Company and the Operating Partnership, on the one hand, and the Holders, on the other hand, shall contribute to the aggregate losses, liabilities, claims, damages and expenses of the nature contemplated by such indemnity agreement incurred by the Company, the Operating Partnership and the Holders, as incurred; provided, however, that no Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any Person that was not guilty of such fraudulent misrepresentation. As between the Company and the Operating Partnership, on the one hand, and the Holders, on the other hand, such parties shall contribute to such aggregate losses, liabilities, claims, damages and expenses of the nature contemplated by such indemnity agreement in such proportion as shall be appropriate to reflect the relative fault of the Company and the Operating Partnership, on the one hand, and the Holders, on the other hand, with respect to the statements or omissions which resulted in such loss, liability, claim, damage or expense, or action in respect thereof, as well as any other relevant equitable considerations. The relative fault of the Company and the Operating Partnership, on the one hand, and of the Holders, on the other hand, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Operating Partnership, on the one hand, or by or on behalf of the Holders, on the other, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, the Operating Partnership and the Holders of the Registrable Securities agree that it would not be just and equitable if contribution pursuant to this Section 4 were to be determined by pro rata allocation or by any other method of allocation that does not take into account the relevant equitable considerations. For purposes of this Section 4, each Affiliate of a Holder, and each director, officer and employee and Person, if any, who controls a Holder or such Affiliate within the meaning of Section 15 of the Securities Act shall have the same rights to contribution as such Holder, and each trustee and officer of the Company, each partner of the Operating Partnership and each Person, if any, who controls the Company or the Operating Partnership within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Company and the Operating Partnership.

-17-

5. Underwritten Registration; Participation Therein. Notwithstanding any provision of this Agreement to the contrary, in no event will the method of distribution of the Registrable Securities take the form of an underwritten offering without the prior written consent of the Company. No Holder may participate in an underwritten registration hereunder unless such Holder (a) agrees to sell such Holder’s Registrable Securities on the basis provided in the underwriting arrangement approved by the Persons entitled hereunder to approve such arrangements and (b) completes and executes all reasonable questionnaires, powers of attorney, indemnities, underwriting agreements, lock-up letters and other documents reasonably required under the terms of such underwriting arrangements.

6. Selection of Underwriters. The Holders of Registrable Securities covered by the Shelf Registration Statement who desire to do so may sell the Securities covered by such Shelf Registration in an underwritten offering, subject to the provisions of Sections 3(l) and 5 hereof. In any such underwritten offering, the underwriter or underwriters and manager or managers that will administer the offering will be selected by the Holders of a majority in aggregate principal amount or number, as the context requires, of the Registrable Securities included in such offering; provided, however, that such underwriters and managers must be reasonably satisfactory to the Company and the Operating Partnership.

7. Miscellaneous.

(a) Rule 144 and Rule 144A. For so long as it is subject to the reporting requirements of Section 13 or 15 of the Exchange Act and any Registrable Securities remain outstanding, each of the Company and the Operating Partnership will file the reports required to be filed by it under the Securities Act and Section 13(a) or 15(d) of the Exchange Act and the rules and regulations adopted by the SEC thereunder; provided, however , that if the Company or the Operating Partnership ceases to be so required to file such reports, it will, upon the request of any Holder of Registrable Securities (a) make publicly available such information as is necessary to permit sales of its securities pursuant to Rule 144 under the Securities Act, (b) deliver such information to a prospective purchaser as is necessary to permit sales of its securities pursuant to Rule 144A under the Securities Act, and (c) take such further action that is reasonable in the circumstances, in each case, to the extent required from time to time to enable such Holder to sell its Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by (i) Rule 144 under the Securities Act, as such rule may be amended from time to time, (ii) Rule 144A under the Securities Act, as such rule may be amended from time to time, or (iii) any similar rules or regulations hereafter adopted by the SEC. Upon the request of any Holder of Registrable Securities, the Company and the Operating Partnership will deliver to such Holder a written statement as to whether it has complied with such requirements.

(b) No Inconsistent Agreements. Neither the Company nor the Operating Partnership has entered into, and will not enter into, any agreement which is inconsistent with the rights granted to the Holders of Registrable Securities in this Agreement or otherwise conflicts with the provisions hereof. The rights granted to the Holders hereunder do not in any way conflict with and are not inconsistent with the rights granted to the holders of the Company’s or the Operating Partnership’s other issued and outstanding securities under any such agreements.

-18-

(c) Amendments and Waivers. The provisions of this Agreement, including the provisions of this sentence, may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, unless the Company and the Operating Partnership have obtained the written consent of Holders of a majority in aggregate principal amount or number, as the context requires, of the outstanding Registrable Securities affected by such amendment, modification, supplement, waiver or departure; provided that no amendment, modification or supplement or waiver or consent to the departure with respect to the provisions of Section 4 hereof shall be effective as against any Holder of Registrable Securities unless consented to in writing by such Holder of Registrable Securities. Notwithstanding the foregoing sentence, (i) this Agreement may be amended, without the consent of any Holder of Registrable Securities, by written agreement signed by the Company, the Operating Partnership and the Initial Purchaser, to cure any ambiguity, correct or supplement any provision of this Agreement that may be inconsistent with any other provision of this Agreement or to make any other provisions with respect to matters or questions arising under this Agreement which shall not be inconsistent with other provisions of this Agreement, (ii) this Agreement may be amended, modified or supplemented, and waivers and consents to departures from the provisions hereof may be given, by written agreement signed by the Company, the Operating Partnership and the Initial Purchaser to the extent that any such amendment, modification, supplement, waiver or consent is, in their reasonable judgment, necessary or appropriate to comply with applicable law (including any interpretation of the Staff of the SEC) or any change therein and (iii) to the extent any provision of this Agreement relates to the Initial Purchaser, such provision may be amended, modified or supplemented, and waivers or consents to departures from such provisions may be given, by written agreement signed by the Initial Purchaser, the Company and the Operating Partnership.

(d) Notices. All notices and other communications provided for or permitted hereunder shall be made in writing by hand-delivery, registered first-class mail, telex, telecopier, or any courier guaranteeing overnight delivery (i) if to a Holder, at the most current address given by such Holder to the Company or the Operating Partnership by means of a notice given in accordance with the provisions of this Section 7(d), which address initially is, with respect to the Initial Purchasers, the respective addresses set forth in the Purchase Agreement; and (ii) if to the Company and the Operating Partnership, initially at the Company’s address set forth in the Purchase Agreement and thereafter at such other address, notice of which is given in accordance with the provisions of this Section 7(d).

All such notices and communications shall be deemed to have been duly given: at the time delivered by hand, if personally delivered; five Business Days after being deposited in the mail, postage prepaid, if mailed; when answered back, if telexed; when receipt is acknowledged, if telecopied; and on the next Business Day, if timely delivered to an air courier guaranteeing overnight delivery.

(e) Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the successors, assigns and transferees of the Initial Purchasers, including, without limitation and without the need for an express assignment, subsequent Holders; provided, however , that nothing herein shall be deemed to permit any assignment, transfer or other disposition of Registrable Securities in violation of the terms of the Purchase Agreement or the Indenture relating to the Notes or declaration of trust of the Company . If any transferee of any Holder shall acquire Registrable Securities, in any manner, whether by operation of law or otherwise, such Registrable Securities shall be held subject to all of the terms of this Agreement, and by taking and holding such Registrable Securities, such Person shall be conclusively deemed to have agreed to be bound by and to perform all of the terms and provisions of this Agreement and such Person shall be entitled to receive the benefits hereof.

(f) Mergers and other Change of Control Transactions. Nothing in this Agreement shall restrict the ability of the Company or the Operating Partnership to consummate a merger, reorganization or any transaction that is covered in the definition of the term “Change in Control” (as defined in the Second Supplemental Indenture), and upon a Change in Control, all obligations of the Company and the Operating Partnership in this Agreement shall terminate except that the Company and the Operating Partnership and the successor, if any, shall remain obligated on those agreements of the Company and Operating Partnership in Section 4 hereof.

(g) Third Party Beneficiaries. Each Holder shall be a third party beneficiary of the agreements made hereunder among the Company, the Operating Partnership and the Initial Purchaser, and the Initial Purchasers shall have the right to enforce such agreements directly to the extent it deems such enforcement necessary or advisable to protect its rights or the rights of Holders hereunder.

(h) Counterparts. This Agreement may be executed in any number of counterparts and by the parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement.

(i) Headings. The headings in this Agreement are for convenience of reference only and shall not limit or otherwise affect the meaning hereof.

(j) GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

NOW, THEREFORE , in consideration of the foregoing and in consideration of the mutual covenants contained herein, the parties agree as follows:

Agreement

1. If the Operating Partnership determines, in its sole discretion, to deliver Net Shares (as such term is defined in the Notes) upon an exchange of the Notes by a holder in accordance with the terms of the Notes and the Indenture, the Company agrees to issue to the Operating Partnership for delivery to such holder the number of Common Shares determined by the Operating Partnership to be delivered to such holder in respect of such Net Shares, and the Operating Partnership hereby directs the Company to deliver such Net Shares to such holder on behalf of the Operating Partnership in accordance with the terms of the Notes and the Indenture.

2. The Operating Partnership agrees to issue to the Company on a concurrent basis a number of “Class A Units” (as defined in the Amended and Restated Agreement of Limited Partnership of the Operating Limited Partnership, as amended from time to time) equal in number to the number of Common Shares issued by the Company pursuant to this Agreement.

3. Miscellaneous.

(a) This Agreement shall be governed by and construed in accordance with the laws of the State of New York.

(b) No provision of this Agreement may be amended, modified or waived, except in writing signed by both parties.

(c) In the event that any claim of inconsistency between this Agreement and the terms of the Indenture arise, as they may from time to time be amended, the terms of the Indenture shall control.

(d) If any provision of this Agreement shall be held illegal, invalid or unenforceable by any court, this Agreement shall be construed and enforced as if such provision had not been contained herein and shall be deemed an Agreement between the parties hereto to the full extent permitted by applicable law.

(e) This Agreement shall be binding upon, inure to the benefit of and be enforceable by the respective successors and assigns of the parties hereto.
