(a) if such Notes are in certificated form, the certificate number(s) of the Notes which the Holder shall 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 Paying Agent shall promptly notify the Company in writing of the receipt by it of any Change of 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 of Control Purchase Date at the offices of the Paying Agent shall be a condition to the receipt by the Holder of the Change of Control Purchase Price therefor. Holders electing to require the Company to repurchase Notes must effect such transfer or delivery to the Paying Agent on or prior to the Change of Control Purchase Date to receive payment of the Change of Control Purchase Price on or within two Business Days after the Change of Control Purchase Date. The Company shall pay the Change of Control Purchase Price within two Business Days after the later of the Change of Control Purchase Date or the time of such transfer or delivery of the Notes.

A Change of Control Purchase Notice may be withdrawn in whole or in part by a Holder by means of a written notice of withdrawal delivered to the office of the Paying Agent prior to the close of business on the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

(a)

the Holder’s name;

(b) the principal amount of Notes in respect of which the Change of Control Purchase Notice is being withdrawn, which must be an integral multiple of $1,000;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

-13-

On or before 10:00 a.m. (New York City time) on the Change of Control Purchase Date, the Company shall deposit with the Paying Agent (or if the Company or an Affiliate of the Company is acting as the Paying Agent, shall segregate and hold in trust) money sufficient to pay the aggregate Change of 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 of Control Purchase Price of such Notes on the Change of 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 of Control Purchase Price after delivery or transfer of the Notes). Such shall 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 Company 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 of Control Purchase Price).

To the extent legally required in connection with a repurchase of Notes, the Company shall comply with the provisions of Rule 13e-4 and other tender offer rules under the Exchange Act then applicable, if any, and will file a Schedule TO or any other schedule required under the Exchange Act.

The Company may arrange for a third party to purchase Notes for which the Company has received a valid Change of 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 shall continue to accrue on the Notes and such Notes shall continue to be Outstanding after the Change of Control Purchase Date for all purposes of the Indenture and shall be fungible with all other Notes then Outstanding.

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

The number of Additional Shares shall be determined by reference to the table below and is based on the date on which such Change of Control transaction becomes effective (the “Effective Date”) and the price (the “Stock Price”) paid per Company Common Share in such Change of Control transaction. If holders of Company Common Shares receive only cash

-14-

in a Change of 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 Conversion 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 Conversion Rate immediately prior to the adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. In addition, the number of Additional Shares shall be subject to adjustment in the same manner as the Conversion 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	$25.72	$30.86	$35.00	$40.00	$45.00	$50.00	$55.00	$60.00	$65.00	$70.00	$75.00
December 11, 2006	6.4800	3.3287	2.0157	1.1708	0.7290	0.4816	0.3312	0.2322	0.1629	0.1126	0.0751
December 15, 2007	6.4800	3.1631	1.8196	1.0011	0.6016	0.3913	0.2682	0.1885	0.1325	0.0913	0.0603
December 15, 2008	6.4001	2.8631	1.5243	0.7749	0.4471	0.2891	0.2004	0.1428	0.1012	0.0698	0.0455
December 15, 2009	6.2659	2.4521	1.1394	05105	0.2836	0.1874	0.1346	0.0985	0.0711	0.0492	0.0318
December 15, 2010	6.1717	1.8377	0.6186	0.2235	0.1290	0.0932	0.0710	0.0538	0.0397	0.0278	0.0180
December 20, 2011	—	—	—	—	—	—	—	—	—	—	—

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 $75.00 per Company Common Share (subject to adjustment as specified in the second preceding paragraph), no Additional Shares shall be issued upon a conversion of Notes;

(c) if the Stock Price is less than $25.72 per Company Common Share (subject to adjustment as specified in the second preceding paragraph), no Additional Shares shall be issued upon a conversion of Notes.

Notwithstanding the foregoing, in no event shall the Conversion Rate (including any Additional Shares) issuable upon a conversion of Notes exceed 38.8802 shares per $1,000 principal amount of Notes, subject to adjustment in the same manner as the Conversion Rate

-15-

pursuant to Section 2.14 hereof. All calculations under this Section 2.10 shall be the responsibility of the Company.

Section 2.11.

Conversion 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 conversion for cash and Company Common Shares or a combination of cash and Company Common Shares, at the Company’s option, at the applicable Conversion 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 December 15, 2025 or (y) under any of the other circumstances set forth in this Section 2.11.

(a) Conversion Upon Satisfaction of Market Price Condition. A Holder may surrender any of its Notes for conversion 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 Company is more than 130% of the Conversion 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 Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the ex-dividend date of the event occurs, during that 30 consecutive trading-day period.

(b) Conversion Upon Satisfaction of Trading Price Condition. A Holder may surrender any of its Notes for conversion 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 applicable Conversion Rate.

The Trustee shall have no obligation to determine the Trading Price of the Notes unless the Company shall have requested such determination, and the Company shall have no obligation to make such request unless a Holder provides the Company 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 Conversion Rate, whereupon the Company 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 Conversion Rate.

(c) Conversion Upon Notice of Redemption. A Holder may surrender for conversion 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 convertible at such time. The right to convert Notes called for redemption pursuant

-16-

to this clause (c) shall expire after the close of business on the second Business Day prior to the Redemption Date unless the Company defaults in making the payment due upon redemption.

(d) Conversion 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 Company or those of the Operating Partnership, 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 Company must notify the Holders of the Notes in writing at least 25 Business Days prior to the ex-dividend date for such distribution. Following the giving of such notice, Holders may surrender their Notes for conversion 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 convert if the Holder may participate, on an as-converted basis, in the distribution without a conversion 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 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 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 of Control, a Holder may surrender Notes for conversion at any time from and including the date that is 25 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 Company shall notify Holders as promptly as practicable following the date it publicly announces such transaction (but in no event less than 25 Business Days prior to the anticipated effective time of such transaction).

If a Change of Control occurs as a result of a transaction described in clauses (1) or (2) of the definition of “Change of Control”, a Holder shall have the right to convert 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 of Control Purchase Notice with respect to a Note, such Holder may not surrender such Note for conversion 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 Company shall notify Holders as promptly as practicable following the date that it publicly announces such Change of Control (but in no event later than five Business Days prior to the Effective Date of such Change of Control).

-17-

If 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 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 conversion of Notes, including the Conversion Value and Net Shares deliverable in connection with such conversion, 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 converted 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 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 convertible 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 First Supplemental Indenture.

The Company 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 December 20, 2011 as a result of a transaction described in clauses (1) or (2) of the definition thereof, the Company shall adjust the Conversion Rate for Notes tendered for conversion in connection with such a Change of Control transaction, as described in Section 2.10 hereof.

(e) Conversion Upon Delisting of Company Common Shares. A Holder of Notes may surrender any of its Notes for conversion 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 for a 30 consecutive Trading Day period.

(f) Partial Conversions and Withdrawal of Purchase Notices. A Holder may convert fewer than all of its Notes so long as the Notes converted 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 of Control Purchase Notice with respect to a Note, such Holder may not surrender such Note for

-18-

conversion 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. Conversion Settlement. Upon a conversion of Notes, the Company shall deliver, in respect of each $1,000 principal amount of Notes tendered for conversion 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 conversion and (2) the Conversion Value, and

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

The Company 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 Company elects to deliver in Company Common Shares (the “Net Shares”) shall be the sum of the Daily Share Amounts (calculated as described below in this paragraph (b)) for each Trading Day during the Applicable Conversion Period. Prior to the close of business on the second Trading Day following the date on which Notes are tendered for conversion, the Company 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.

The Company 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 Conversion Period is equal to the greater of:

(a)

zero; and

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

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

20 x CSP

where

CSP = the Closing Sale Price of Company Common Shares on such Trading Day; provided that if the Notes have become convertible into securities or property other than our Common Shares, “CSP” is equal to the average of the closing sale prices of such securities for each Trading Day in the Applicable Conversion Period or, in the case of other, property, the fair market value thereof as determined in good faith by the Board of Trustees, and

-19-

CR = the applicable Conversion Rate

The Company shall determine the Conversion Value, Principal Return, Net Amount, Net Cash Amount and the number of Net Shares, as applicable, promptly after the end of the Applicable Conversion Period. The Company 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 Conversion Period.

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

To convert the Notes, a Holder must (a) complete and manually sign the irrevocable conversion notice on the reverse of the Note (or complete and manually sign a facsimile of such notice) and deliver such notice to the Conversion Agent at the office maintained by the Conversion Agent for such purpose, (b) with respect to Notes which are in certificated form, surrender the Notes to the Conversion 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 Conversion 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 conversion.

Notes in respect of which a Holder has delivered an Optional Repurchase Notice or Change of Control Purchase Notice may be converted 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 conversion, the Company 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 conversion. A Holder may convert fewer than all of such Holder’s Notes so long as the Notes converted are an integral multiple of $1,000 principal amount and the remaining principal amount of the Notes is in an authorized denomination.

Upon surrender of a Note for conversion by a Holder, such Holder shall deliver to the Company cash equal to the amount that the Company is required to deduct and withhold under applicable law in connection with the conversion; provided, however, if the Holder does not deliver such cash, the Company 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 conversion of a Note, a Holder shall not receive any cash payment representing accrued and unpaid interest on such Note. Instead, upon a conversion of Notes, the Company shall deliver to tendering Holders only the consideration specified in Section 2.12. Delivery of cash and Company Common Shares, if any, upon a conversion of Notes shall be deemed to satisfy the Company’s obligation to pay the principal amount of the Notes and any

-20-

accrued and unpaid interest, except as otherwise provided herein. Accordingly, upon a conversion of Notes, except as otherwise provided herein, any accrued and unpaid interest shall be deemed paid in full rather than cancelled, extinguished or forfeited. In no event shall the Conversion 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 conversion of such Notes at any time after the close of business on the applicable Regular Record Date. Notes tendered for conversion 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 conversion with respect to such Notes.

Upon conversion of a Note, the Company, 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 conversion, 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.

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 Company, at its option, of Net Shares in accordance with the provisions of Section 2.12 in connection with the conversion by a Holder of Notes.

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

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 conversion of the Notes at the applicable Conversion 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 a conversion 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 a conversion of Notes and, prior to delivering any Company Common Shares upon a conversion of

-21-

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 conversion of Notes.

Section 2.14. Conversion Rate Adjustments. The Conversion 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 Conversion Rate shall be adjusted based on the following formula:

CR₁ =

CR₀ x (OS₁/OS₀)

where

CR₀ =

the Conversion Rate in effect immediately prior to the adjustment relating to such event

CR₁ =

the new Conversion 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 Conversion Rate shall be readjusted to the Conversion 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 Conversion Rate shall be adjusted based on the following formula:

CR₁ =

CR₀ x ((OS₀+X)/(OS₀+Y))

-22-

where

CR₀ =

the Conversion Rate in effect immediately prior to the adjustment relating to such event

CR₁ =

the new Conversion 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 Conversion Rate, no adjustment to the Conversion Rate shall be made.

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 Conversion Rate shall be readjusted to the Conversion 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,

-23-

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

(iii)

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

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

CR₁ =

CR₀ x (SP₀/(SP₀-FMV))

where

CR₀ =

the Conversion Rate in effect immediately prior to the adjustment relating to such event

CR₁ =

the new Conversion 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 Conversion 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 Conversion Rate shall be adjusted based on the following formula:

CR₁ =

CR₀ x ((FMV₀+MP₀)/MP₀)

where

CR₀ =

the Conversion Rate in effect immediately prior to the adjustment relating to such event

CR₁ =

the new Conversion Rate taking such event into account

FMV₀ =

the value, based on the average of the Closing Sale Prices of the capital stock or similar equity interest distributed to holders of

-24-

Company Common Shares over the first 10 consecutive Trading Days after the effective date of the Spin-Off applicable to one Company Common Share

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 Conversion 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 Conversion Rate shall be readjusted to be the Conversion 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 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 $0.20 (the “Reference Dividend”) multiplied by the number of Company Common Shares outstanding on the record date for such distribution, the Conversion Rate shall be adjusted based on the following formula:

CR₁ =

CR₀ x ((SP₀-RD)/(SP₀-C))

where

CR₀ =

the Conversion Rate in effect immediately prior to the adjustment relating to such event

CR₁ =

the new Conversion 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

RD=

the Reference Dividend

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.

An adjustment to the Conversion 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

-25-

Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

Notwithstanding the foregoing, if an adjustment to the Conversion 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 Conversion 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 Conversion Rate; provided that no adjustment shall be made to the Reference Dividend for any adjustment made to the Conversion Rate pursuant to this paragraph (d).

(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 Conversion Rate shall be adjusted based on the following formula:

CR₁ =

CR₀ x ((AC + (SP₁ x OS₁))/(SP₁ x OS₀))

where

CR₀=

the Conversion Rate in effect immediately prior to the adjustment relating to such event

CR₁ =

the new Conversion Rate taking such event into account

AC =

the aggregate value of all cash and any other consideration (as determined in good faith 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.

-26-

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

Any adjustment to the Conversion 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 Conversion Rate shall be readjusted to be the Conversion 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 Conversion Rate pursuant to paragraph (d) or (e) above, in no event shall the Conversion Rate exceed 38.8802, 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 a conversion of Notes in respect of which the Company has elected to deliver Net Shares, in addition to such Net Shares, rights under any shareholder rights agreement the Company may then have in effect unless, prior to conversion, 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 convertible, the Conversion 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.

In addition to the adjustments pursuant to paragraphs (a) through (e) above, the Company may increase the Conversion 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 Company may also, from time to time, to the extent permitted by applicable law, increase the Conversion Rate by any amount for any period if the Company has determined that such increase would be in the best interests of the Company. If the Company makes such determination, it shall be conclusive and the Company shall mail to Holders of the Notes a notice of the increased Conversion Rate and the period during which it shall be in effect at least fifteen (15) days prior to the date the increased Conversion Rate takes effect in accordance with applicable law.

If, in connection with any adjustment to the Conversion 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 Company, the Company 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

-27-

a Holder upon a conversion 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 Company shall not make any adjustment to the Conversion Rate if Holders of the Notes are permitted to participate, on an as-converted basis, in the transactions described above without converting their Notes.

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

(i) the issuance of Company Common Shares pursuant to any public or private follow-on offering;

(ii) 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 Company and the investment of additional optional amounts in Company Common Shares under any plan;

(iii) 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 Company;

(iv) 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;

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

(vi) accumulated and unpaid dividends or distributions;

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

(viii) the issuance of limited partnership units by the Operating Partnership for cash or property and the issuance of Company Common Shares for cash or property or the payment of cash upon redemption thereof; provided that the acquisition of property upon the issuance of limited partnership units will not result in any anti-dilution adjustments.

No adjustment in the Conversion Rate shall be required unless the adjustment would require an increase or decrease of at least 1% of the Conversion Price. If the adjustment is not made because the adjustment does not change the Conversion 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

-28-

adjustments not previously made shall be made on the 10^th Business Date preceding the applicable Redemption Date.

Whenever the Conversion Rate is adjusted as herein provided, the Company shall as promptly as reasonably practicable file with the Trustee and any Conversion Agent other than the Trustee an Officers’ Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment becomes effective and shall mail such notice of such adjustment of the Conversion 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 Conversion Rate be adjusted so that the Conversion 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 Person may own, or be deemed to own by virtue of the attribution rules of the Code, more than 9.8% in value or number, whichever is more restrictive, of Company Common Shares or the issued and outstanding shares of any of the Company’s other classes or series of shares of beneficial interest. Notwithstanding any other provision of the Notes or the instructions contained herein, no Holder of Notes shall be entitled to convert 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 Company 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.

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 convertible 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 Original 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

-29-

theretofore authenticated and delivered (except lost, stolen or destroyed Notes which have been replaced or paid as provided in Section 306 of the Original 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 of Control Repurchase Date or upon conversion or otherwise, the Company 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 Original Indenture for the Notes) and/or Company Common 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, and securities deliverable in respect of, 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 Original Indenture shall have occurred and be continuing on the 123rd day after such date; (C) the Company has paid, or caused to be paid, all sums payable by it under the Indenture in respect of the Notes; and (D) the Company has delivered irrevocable instructions to the Trustee for the Notes under the Indenture to apply the deposited money and Company Common Shares toward the payment of such Notes. In addition, the Company 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.

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

“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 Company and the Trustee, the Company, when authorized by or pursuant to a 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;

(g) reduce the percentage in principal amount of the Outstanding Notes, the consent of whose Holders is required for any such supplemental indenture, or the consent of whose Holders is required for any waiver with respect to the Outstanding Notes (or compliance with specified provisions of the Indenture or specified defaults and consequences thereunder) or to reduce the quorum or voting requirements set forth in the Indenture; or

(h) modify any of the provisions of this Section 902, Section 513 or Section 1013 of the Original Indenture, except to increase the required percentage to effect such action or to provide that specified other provisions of the Indenture which may not be modified or waived without the consent of the Holders of each Outstanding Note affected thereby.

-31-

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 2.22. Calculations in Respect of the Notes.

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 conversion of such 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 Company, 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.

-32-

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 Company 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 SHALL NOT, WITHIN TWO YEARS AFTER THE LATER OF THE ORIGINAL ISSUANCE OF THIS SECURITY AND THE LAST DATE ON WHICH ACADIA REALTY TRUST OR AN AFFILIATE THEREOF WAS THE OWNER OF THIS SECURITY, RESELL OR OTHERWISE TRANSFER THIS SECURITY OR THE ACADIA COMMON SHARES ISSUABLE UPON CONVERSION OF SUCH SECURITY EXCEPT (A) TO ACADIA REALTY TRUST OR ANY OF ITS 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 SHALL DELIVER TO EACH PERSON TO WHOM THIS SECURITY IS TRANSFERRED PURSUANT TO CLAUSE 2(B) 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 ACADIA REALTY TRUST 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. IF THE PROPOSED TRANSFER IS PURSUANT TO CLAUSE 2(C) ABOVE, THE HOLDER MUST, PRIOR TO SUCH TRANSFER, FURNISH TO THE TRUSTEE, SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS ACADIA REALTY TRUST 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,

-33-

THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. THIS LEGEND SHALL 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 ACADIA REALTY TRUST OR AN AFFILIATE THEREOF WAS THE OWNER OF THIS SECURITY.

Each share certificate representing Company Common Shares issued upon conversion of Notes bearing a legend will bear a comparable legend (except that the legend will indicate that the two-year period commenced on the original issuance of the Notes) until it is removed in conformity with applicable securities laws.

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 Company 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 public announcement 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 Company 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.

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 Company or any Affiliate thereof may not be resold by the Company or such Affiliate and shall 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 shall be cancelled promptly by the Trustee.

-34-

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. If at any time during the holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any successor provision) the Company is not subject to Section 13 or 15(d) under the Exchange Act, the Company covenants and agrees that it shall make available to any holder or beneficial holder of Notes or any Company Common Shares issued upon conversion 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. (a) So long as the Notes are outstanding and whether or not required by the Commission, the Company will furnish to the Trustee within 15 days of the time periods specified in the Commission’s rules and regulations: (i) all annual and quarterly financial information that would be required to be contained in filings with the SEC on Forms 10-K and 10-Q if the Company were required to file those filings, including a related “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and, with respect to the annual information only, a report on the annual financial statements by the Company’s certified independent accountants; and (ii) all current reports that would be required to be filed with the SEC on Form 8-K if we were required to file such reports.

(b) If the Company is not subject to Sections 13 and 15(d) of the Exchange Act, the Company will (A) furnish to the holders of the Notes, without cost to such holders, a copy of the information and reports referred to in clause (a) above within 15 days of the time periods specified in the Commission’s rules and regulations, and (B) upon written request and payment of the reasonable cost of duplication and delivery, promptly supply to any prospective holder of the debt securities a copy of the information and reports referred to in clause (a).

In addition, whether or not required by the Commission, the Company will file a copy of the information and reports referred to above with the Commission for public availability within the time periods specified in the Commission’s rules and regulations (unless the Commission will not accept such a filing).

Section 2.28. Additional Interest Notice. In the event that the Company is required to pay Additional Interest to Holders of Notes pursuant to the Registration Rights Agreement, the Company shall provide written notice (“Additional Interest Notice”) to the Trustee of its obligation to pay Additional Interest no later than fifteen (15) calendar days prior

-35-

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 Company 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.
