A Holder may exercise its rights specified in this Section 2.09 upon delivery of a written notice of such Holder’s exercise of its repurchase right (a “Change in Control Purchase Notice”) to the Trustee (or any Paying Agent) at any time prior to the close of business on the third Business Day prior to the Change in Control Purchase Date, stating:

(a) if such Notes are in certificated form, the certificate number(s) of the Notes which the Holder will deliver to be repurchased;

(b) the portion of the principal amount of the Notes to be repurchased, in multiples of $1,000, provided that the remaining principal amount of Notes is in an authorized denomination; and

The Trustee (or any Paying Agent) shall promptly notify the Operating Partnership and the Company in writing of the receipt by it of any Change in Control Purchase Notice.

Book-entry transfer of Notes in book-entry form in compliance with appropriate procedures of the Depositary or delivery of Notes in certificated form (together with all necessary endorsements) to the Paying Agent on or after the Change in Control Purchase Date at the offices of the Paying Agent shall be a condition to the receipt by the Holder of the Change in Control Purchase Price therefor. Holders electing to require the Operating Partnership to repurchase Notes must effect such transfer or delivery to the Paying Agent prior to the Change in Control Purchase Date to receive payment of the Change in Control Purchase Price on or within two Business Days after the Change in Control Purchase Date. The Operating Partnership shall pay the Change in Control Purchase Price within two Business Days after the later of the Change in Control Purchase Date or the time of such transfer or delivery of the Notes.

A Change in Control Purchase Notice may be withdrawn in whole or in part by a Holder by means of a written notice of withdrawal delivered to the office of the Paying Agent prior to the close of business on the third Business Day prior to the Change in Control Purchase Date specifying:

(a) the Holder’s name;

(b) the principal amount of Notes in respect of which the Change in Control Purchase Notice is being withdrawn, which must be an integral multiple of $1,000;

(c) if the Notes subject to the notice of withdrawal are in certificated form, the certificate number(s) of all Notes subject to the notice of withdrawal; and

(d) the principal amount of Notes, if any, that remains subject to the Change in Control Purchase Notice, which must be an integral multiple of $1,000.

If Notes subject to the notice of withdrawal are in book-entry form, the above notices must also comply with the applicable procedures of the Depositary.

On or before 10:00 a.m. (New York City time) on the Change in Control Purchase Date, the Operating Partnership shall deposit with the Paying Agent (or if the Operating Partnership or an Affiliate of the Operating Partnership is acting as the Paying Agent, shall segregate and hold in trust) money sufficient to pay the aggregate Change in Control Purchase Price of the Notes to be purchased pursuant to this Section 2.09. If the Paying Agent holds, in accordance with the terms of the Indenture, money sufficient to pay the Change in Control Purchase Price of such Notes on the Change in Control Purchase Date, then, on and after such date, such Notes shall cease to be Outstanding and interest on such Notes shall cease to accrue and all rights of the Holders of such Notes shall terminate (other than the right to receive the Change in Control Purchase Price after delivery or transfer of the Notes). Such will be the case whether or not book-entry transfer of the Notes in book-entry form is made and whether or not Notes in certificated form, together with the necessary endorsements, are delivered to the Paying Agent.

Notwithstanding the foregoing, no Notes may be repurchased by the Operating Partnership in accordance with the provisions of this Section 2.09 if there has occurred and is continuing an Event of Default with respect to the Notes (other than a default in the payment of the Change in Control Purchase Price).

The Operating Partnership may arrange for a third party to purchase Notes for which the Operating Partnership has received a valid Change in Control Purchase Notice that has not been properly withdrawn, in the manner and otherwise in compliance with the requirements set forth herein and in the Notes. If a third party purchases any Notes under such circumstances, then interest will continue to accrue on the Notes and such Notes will continue to be Outstanding after the Change in Control Purchase Date for all purposes of the Indenture and will be fungible with all other Notes then Outstanding.

Section 2.10. Make Whole Amount. If a Change in Control occurs prior to January 18, 2012 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 will 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) will be adjusted as of any date on which the Exchange Rate of the Notes is adjusted. The adjusted Stock Prices will 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 will 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:


Effective	Stock Price
Date	$36.21		$40.00		$45.00		$50.00		$60.00		$70.00		$80.00		$90.00		$100.00
June 27, 2006		4.3624		3.1072		2.0598		1.4864		0.9190		0.6840		0.5749		0.5031		0.4507
July 15, 2007		4.3624		3.0078		1.9270		1.3190		0.7702		0.5661		0.4734		0.4150		0.3722
July 15, 2008		4.3624		2.8765		1.7748		1.1194		0.6071		0.4406		0.3692		0.3246		0.2918
July 15, 2009		4.3624		2.6984		1.5273		0.8772		0.4301		0.3145		0.2669		0.2365		0.2132
July 15, 2010		4.3624		2.4372		1.1807		0.5665		0.2407		0.1847		0.1600		0.1424		0.1285
July 15, 2011		4.3624		2.0126		0.5727		0.1616		0.0725		0.0617		0.0541		0.0482		0.0435
January 18, 2012		4.3624		1.7458		0.0000		0.0000		0.0000		0.0000		0.0000		0.0000		0.0000

The exact Stock Prices and Effective Dates may not be set forth on 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 will 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 $100.00 per Company Common Share (subject to adjustment as specified in the second preceding paragraph), no Additional Shares will be issued upon an exchange of Notes; and

(c) if the Stock Price is less than $36.21 per Company Common Share (subject to adjustment as specified in the second preceding paragraph), no Additional Shares will be issued upon an exchange of Notes.

Notwithstanding the foregoing, in no event shall the total number of Company Common Shares issuable upon an exchange of Notes exceed 27.6166 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.

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, 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 at any time on or after July 15, 2025 and also under any of the 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 September 30, 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 is more than 125% 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.

(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 third Business Day prior to the Redemption Date, even if the Notes are not otherwise exchangeable at such time. The right to exchange Notes pursuant to this clause (c) will expire after the close of business on the third Business Day prior to the Redemption Date unless the Operating Partnership defaults in making the payment due upon redemption. 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. However, 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.

(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 certain 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 will 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.

In addition, if the Operating Partnership or the Company is party to a consolidation, merger or binding share exchange pursuant to which all of the 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 will 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 will 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 or binding share exchange pursuant to which all of the Company Common Shares are exchanged for cash, securities or other property, then at the effective time of the transaction any exchange of Notes and the Exchange Value will be based on the kind and amount of cash, securities or other property 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 or binding share exchange 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 stockholder election, such consideration will 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. If a Change of Control occurs prior to January 18, 2012 as a result of a transaction described in clauses (1) or (2) of the definition thereof, the Operating Partnership will 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 U.S. national or regional securities exchange or quoted on the Nasdaq National Market for a 30 consecutive Trading Day period.

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”) will 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 will be paid in cash and the portion that will be delivered in the form of Net Shares.

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 will 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, 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.

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 will not receive any cash payment representing accrued and unpaid interest on such Note. Instead, upon an exchange of Notes, the Operating Partnership will 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 will 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 will be deemed paid in full rather than cancelled, extinguished or forfeited. In no event will 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 will 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 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, will 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 Company Common Shares will not be issued or delivered unless all taxes and duties, if any, payable by the Holder have been paid.

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 common stock a sufficient number of Company Common Shares to permit the exchange of the Notes at the applicable Exchange Rate. 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 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 will 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.

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 will be adjusted based on the following formula:

	ER1 =		ER0 x (OS0+X)/(OS0+Y)

	where		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.

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 will 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.

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 will 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 will occur on the 10th Trading Day from and including 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.

(d) If the Company makes any cash dividend or distribution in respect of 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 such quarterly fiscal period, exceeds the product of $0.33 (the “Reference Dividend”) multiplied by the number of Company Common Shares outstanding on the record date for such distribution, the Exchange Rate will 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.

The Reference Dividend shall be subject to adjustment on account of any of the events set forth in paragraphs (a), (b) and (c) above and paragraph (e) below. Any such adjustment will be effected by multiplying the Reference Dividend by a fraction, the numerator of which will equal the Exchange Rate in effect immediately prior to the adjustment on account of such event and the denominator of which will equal the Exchange Rate as adjusted.

(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 will 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 will 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 will the Exchange Rate exceed 27.6166, 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 will 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 that the Operating Partnership elects to deliver as Net Shares upon exchange of Notes, the Exchange Rate will 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. In lieu of any such adjustment, the Company may amend such applicable shareholder rights agreement to provide that upon an exchange of Notes the Holders will receive, in addition to Company Common Shares that the Operating Partnership elects to deliver as Net Shares upon such exchange, the rights which would have attached to such Company Common Shares if the rights had not become separated from the Company Common Shares under such applicable shareholder rights agreement. To the extent that the Company adopts any future shareholder rights agreement, upon an exchange of Notes in respect of which the Operating Partnership elects to deliver Company Common Shares as Net Shares, a Holder of Notes shall receive, in addition to such Company Common Shares, the rights under the future shareholder rights agreement whether or not the rights have separated from Company Common Shares at the time of exchange and no adjustment will be made in accordance with paragraph (c) or otherwise.

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 will be conclusive and Operating Partnership will mail to Holders of the Notes a notice of the increased Exchange Rate and the period during which it will 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 an Additional Interest payment, 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 will 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;

(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 will 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 will be carried forward and taken into account in any future adjustment. All required calculations will 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 will be made on the applicable Redemption Date. Except as specifically described above, the applicable Exchange Rate will 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 Rate 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.

(a) Section 801(a) of the First Supplemental Indenture is modified and amended for purposes of the Notes to read as follows:

“the Issuer or the Guarantor shall be the continuing entity, or the successor Person or its transferees or assignees of such assets (if other than the Issuer or the Guarantor), formed by or resulting from any such consolidation or merger or which shall have received the transfer of such assets by lease (subject to the continuing obligations of Issuer and the Guarantor set forth in Section 802) or otherwise, either directly or indirectly, shall expressly assume the payment of the principal of and interest on all the Notes, in the case of the Issuer and the Guarantor, or the obligations of the Guarantor under the Guarantee, as the case may be, and the due and punctual performance and observance of all of the other covenants in this Indenture;”

Section 2.17. Satisfaction and Discharge. The provisions of ARTICLE FOURTEEN of the Indenture shall not be applicable to the Notes. The Operating Partnership and the Company may satisfy and discharge their obligations under the Indenture by delivering to the Trustee for cancellation all Outstanding Notes or by depositing with the Trustee, the Paying Agent or the Exchange Agent, if applicable, 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 sufficient to pay all of the Outstanding Notes and paying all other sums payable under the Notes and the Indenture in respect of the Notes.

“With the consent of the Holders of a majority in principal amount of all Outstanding Securities affected by such supplemental indenture (voting together as a single class), by Act of said Holders delivered to the Issuer, the Guarantor and the Trustee, the Issuer, when authorized by or pursuant to a Board Resolution, the Guarantor (when authorized by or pursuant to a 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 Securities under this Indenture; provided, however, that no such supplemental indenture shall, without the consent of the Holder of each Outstanding Note affected thereby:

(h) modify or affect the terms and conditions of the obligations of the Company or any successor entity, as co-obligor and guarantor of the Notes.

It shall not be necessary for any Act of Holders under this Section 2.19 to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such Act shall approve the substance thereof.

A supplemental indenture which changes or eliminates any covenant or other provision of this Indenture which has expressly been included solely for the benefit of one or more particular series of Securities, or which modifies the rights of the Holders of Securities of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under this Indenture of the Holders of Securities of any other series.

Section 2.20. Full and Unconditional Guarantee by the Company. The provisions of ARTICLE SEVENTEEN of the Indenture shall be applicable to the Notes and the Notes shall be “Guaranteed Securities” within the meaning of the Indenture.

Section 2.25. Restrictions on Transfer. (a) Every Note (and all Notes issued in exchange therefor or in substitution thereof) that bears or is required under this Section 2.25(a) to bear the legend set forth in this Section 2.25(a) (together with any Company Common Shares issued upon exchange of the Notes, collectively, the “Restricted Securities”) shall be subject to the restrictions on transfer set forth in this Section 2.25(a) (including those set forth in the legend below) unless such restrictions on transfer shall be waived by written consent of the Issuer, and the Holder of each such Restricted Security, by such Holder’s acceptance thereof, agrees to be bound by all such restrictions on transfer. As used in this Section 2.25(a), the term “transfer” means any sale, pledge, loan, transfer or other disposition whatsoever of any Restricted Security or any interest therein.

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;

(2) AGREES THAT IT WILL NOT, WITHIN TWO YEARS AFTER THE LATER OF THE ORIGINAL ISSUANCE OF THIS SECURITY AND THE LAST DATE ON WHICH THE ISSUER OR THE COMPANY OR AN AFFILIATE THEREOF WAS THE OWNER OF THIS SECURITY, RESELL OR OTHERWISE TRANSFER THIS SECURITY OR THE COMMON SHARES ISSUABLE UPON EXCHANGE OF SUCH SECURITY EXCEPT (A) TO THE COMPANY, THE ISSUER OR ANY OF THEIR RESPECTIVE SUBSIDIARIES, (B) TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, (C) PURSUANT TO THE

EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT (IF AVAILABLE), OR (D) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT AND WHICH CONTINUES TO BE EFFECTIVE AT THE TIME OF SUCH TRANSFER; AND

(3) AGREES THAT IT WILL 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. THIS LEGEND WILL BE REMOVED UPON THE EARLIER OF THE TRANSFER OF THIS SECURITY PURSUANT TO CLAUSE 2(C) OR 2(D) ABOVE OR THE EXPIRATION OF TWO YEARS FROM 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.

Any Notes that are Restricted Securities and as to which such restrictions on transfer shall have expired in accordance with their terms or as to conditions for removal of the foregoing legend set forth therein have been satisfied may, upon surrender of such Note for exchange to the Securities Registrar in accordance with the provisions of this Section 2.25, be exchanged for a new Note or Notes, of like tenor and aggregate principal amount, which shall not bear the restrictive legend required by this Section 2.25(a). 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 will 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 will 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.

(b) 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 will be surrendered to the Trustee for cancellation. Upon expiration of the holding period applicable Restricted Securities under Rule 144(k) under the Securities Act (or any successor provision), the Notes may, to the extent permitted by applicable law, be reissued or sold or may be surrendered to the Trustee for cancellation. Any Notes surrendered for cancellation may not be reissued or resold and will be canceled promptly by the Trustee.

(c) 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.

Section 2.26. Rule 144A Information Requirement. Within the period prior to the expiration of the holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any successor provision), each of the Issuer and the Guarantor covenants and agrees that it shall, during any period in which it is not subject to Section 13 or 15(d) under the Exchange Act, make available to any holder or beneficial holder of Notes or any Company Common Shares issued upon exchange thereof which continue to be Restricted Securities in connection with any sale thereof and any prospective purchaser of Notes or such Company Common Shares designated by such holder or beneficial holder, the information required pursuant to Rule 144A(d)(4) under the Securities Act upon the request of any holder or beneficial holder of the Notes or such Company Common Shares, all to the extent required to enable such holder or beneficial holder to sell its Notes or Company Common Shares without registration under the Securities Act within the limitation of the exemption provided by Rule 144A unless a resale shelf registration statement in respect of the Notes and the Company Common Shares is available.

Section 2.27. Provision of Financial Information. Each of the Issuer and the Guarantor, for so long as any Notes are outstanding, within 15 days after it is required to file the same with the Commission, will furnish to the Holders of the Notes, or cause the Trustee to furnish to the Holders of the Notes, all annual, quarterly and other reports that it may be required to file with the Commission pursuant to Section 13 or Section 15(d) of the Exchange Act. Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Issuer’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on an Officers’ Certificate). If either the Issuer or the Guarantor is not required to file the foregoing

forms or reports with the commission, then it will file with the Trustee and the Commission such reports as may be prescribed by the Commission at such time.

Section 2.28. Additional Interest Notice. In the event that the Issuer is required to pay Additional Interest to Holders of Notes pursuant to the Registration Rights Agreement, the Issuer will provide written notice (“Additional Interest Notice”) to the Trustee of its obligation to pay Additional Interest no later than fifteen (15) calendar days prior to the proposed payment date for Additional Interest, and the Additional Interest Notice shall set forth the amount of Additional Interest to be paid by the Issuer on such payment date. 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.

ARTICLE THREE
