All Notes presented or surrendered for registration of transfer or for exchange, repurchase or conversion shall (if so required by the Company, the Trustee, the Security Registrar or any co-registrar) be duly endorsed, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Company and duly executed, by the Noteholder thereof or his attorney-in-fact duly authorized in writing.

No service charge shall be charged to the Noteholder for any exchange or registration of transfer of Notes, but the Company or the Trustee may require payment of a sum sufficient to cover any tax, assessments or other governmental charges that may be imposed in connection therewith.

All Notes issued upon any registration of transfer or exchange of Notes in accordance with this Annex A of the Twelfth Supplemental Indenture shall be the valid, binding and legal obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Annex A of the Twelfth Supplemental Indenture as the Notes surrendered upon such registration of transfer or exchange.

(b) Every Note (and all Notes issued in exchange therefor or in substitution thereof) that bears or is required under this Section 2.06(b) to bear the legend set forth in this Section 2.06(b) (together with any Common Stock issued upon exchange of the Notes, collectively, the “Restricted Securities”) shall be subject to the restrictions on transfer set forth in this Section 2.06(b) (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 2.06(b), 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, or otherwise has become, 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:

A-9

THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE SECURITIES LAWS. NEITHER THIS SECURITY NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE OFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. THE HOLDER OF THIS SECURITY BY ITS ACCEPTANCE HEREOF AGREES TO OFFER, SELL OR OTHERWISE TRANSFER SUCH SECURITY OR THE COMMON SHARES ISSUABLE UPON CONVERSION OF SUCH SECURITY, PRIOR TO THE DATE WHICH IS TWO YEARS AFTER THE LATER OF THE ORIGINAL DATE OF ISSUANCE OF THIS SECURITY AND THE LAST DATE ON WHICH THE COMPANY OR ANY AFFILIATE OF THE COMPANY WAS THE OWNER OF THIS SECURITY (OR ANY PREDECESSOR OF THIS SECURITY) (THE “RESALE RESTRICTION TERMINATION DATE”) ONLY (A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, (B) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, (C) FOR SO LONG AS THE SECURITIES ARE ELIGIBLE FOR RESALE PURSUANT TO RULE 144A UNDER THE SECURITIES ACT (“RULE 144A”), TO A PERSON IT REASONABLY BELIEVES IS A “QUALIFIED INSTITUTIONAL BUYER” AS DEFINED IN RULE 144A THAT PURCHASES FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER TO WHOM NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, OR (D) PURSUANT TO ANOTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, SUBJECT TO THE COMPANY’S AND THE TRUSTEE’S RIGHT PRIOR TO ANY SUCH OFFER, SALE OR TRANSFER PURSUANT TO CLAUSE (D) PRIOR TO THE RESALE RESTRICTION TERMINATION DATE TO REQUIRE THE DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATION AND/OR OTHER INFORMATION SATISFACTORY TO EACH OF THEM. THIS LEGEND WILL BE REMOVED UPON THE REQUEST OF A HOLDER AFTER THE RESALE RESTRICTION TERMINATION DATE.

A-10

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 2.06, 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 2.06(b). If such Restricted Security surrendered for exchange is represented by a Global Note bearing the legend set forth in this Section 2.06(b), 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 2.06(b) shall be increased by an equal principal amount. If a Global Note without the legend set forth in this Section 2.06(b) 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 Common Stock issued upon exchange of the Notes 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 Company knows of the effectiveness of any such amendment to shorten the two-year period under Rule 144(d), unless such changes would otherwise be prohibited by, or would cause a violation of, the federal securities laws applicable at the time, the Company 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.

(c) 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 will be surrendered to the Trustee for cancellation. Upon expiration of the holding period applicable to sales of 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.

(d) 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.

The Company may also from time to time repurchase the Notes in open market purchases by tender at any price or by private agreement without prior notice to Noteholders.

(b) If any Note selected for partial redemption is exchanged in part before termination of the exchange right with respect to the portion of the Note so selected, the exchanged portion of such Note shall be deemed to be part of the portion selected for redemption. Notes which have been exchanged subsequent to the Trustee commencing selection of Notes to be redeemed but prior to redemption of such Notes shall be treated by the Trustee as Outstanding for the purpose of such selection.

Section 3.03 Notice of Redemption. The provisions of Section 1104 of the Base Indenture shall govern notices of redemption of the Notes; provided, however, that in addition to the information specified in Section 1104 of the Base Indenture, notices of redemption of the Notes shall also state:

February 1, 2012 at a rate (the “Exchange Rate”) of 5.8752 shares of Common Stock (subject to adjustment by the Company as provided in Section 8.04) per $1,000 principal amount of Notes (the “Exchange Obligation”) under the circumstances and during the periods set forth below. On and after February 1, 2012, regardless of the conditions described in clause (b) through (f) below, upon compliance with the provisions of this Article VIII and subject to Section 8.11 hereof, a Noteholder shall have the right, at such holder’s option, to exchange all or any portion (if the portion to be exchanged is $1,000 principal amount or an integral multiple thereof) of such Note at any time prior to the close of business on the scheduled Trading Day immediately preceding the Maturity Date at an Exchange Rate of 5.8752 shares of Common Stock (subject to adjustment by the Company as provided in Section 8.04) per $1,000 principal amount of Notes.

(b) (1) A Holder of Notes shall have the right, at such Holder’s option, to exchange its Notes prior to February 1, 2012, during the five Business Day period immediately after any ten consecutive Trading Day period (the “Measurement Period”) in which the Trading Price per $1,000 principal amount of Notes for each day of such Measurement Period was less than 98% of the product of the Last Reported Sale Price of the Common Stock on such date and the Exchange Rate on such date, all as determined by the Trustee in the manner described in the immediately succeeding paragraph. The Trustee shall have no obligation to determine the Trading Price of the Notes unless requested by the Company to do so in writing, and the Company shall have no obligation to make such request unless a Noteholder or Noteholders of at least $1,000,000 aggregate principal amount of Notes provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of the Notes would be less than 98% of the product of the Last Reported Sale Price at such time and the then-applicable Exchange Rate, at which time the Company shall select three independent nationally recognized securities dealers (each, an “Independent Securities Dealer”), request that the Independent Securities Dealers provide a secondary market quotation for the Notes and provide such determination to the Company and the Trustee in writing, and the Company shall instruct the Independent Securities Dealers to provide a secondary market quotation for the Notes beginning on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of the Notes is greater than or equal to 98% of the product of the Last Reported Sale Price on such date and the then-applicable Exchange Rate. If the Trading Price condition set forth above has been met, the Company shall so notify the Noteholders. If at any time after the Trading Price condition set forth above has been met, the Trading Price per $1,000 principal amount of Notes is greater than 98% of the product of the Last Reported Sale Price on such date and the then-applicable Exchange Rate, the Company shall so notify the Noteholders.

A-17

basis of such quotations, the Trustee shall determine the Trading Price of the Notes, and provide such determination to the Company. Absent manifest error, the Trustee’s determination of the Trading Price will be binding on the Company. Unless and until a Responsible Officer of the Trustee shall have received a request from the Company for determination of the Trading Price for the Notes and the Officers’ Certificate contemplated herein, the Trustee shall have no obligation to make any determination of the Trading Price of the Notes or whether the Trading Price condition has been met.

(c) A Holder of Notes shall have the right, at such Holder’s option, to exchange Notes during any calendar quarter after the quarter ended March 31, 2007, and only during such calendar quarter, if the Last Reported Sale Price for the Common Stock for at least 20 Trading Days during the period of 30 consecutive Trading Days ending on the last Trading Day of the previous calendar quarter exceeds 130% of the Exchange Price (the “Exchange Trigger Price”) on such last Trading Day, which Exchange Price shall be subject to adjustment in accordance with this Article VIII. The Exchange Agent shall, on the Company’s behalf, determine at the beginning of each calendar quarter whether the Notes are exchangeable as a result of the price of the Common Stock as contemplated in the previous sentence and notify the Company and the Trustee.

(d) In the event that the Company has delivered a notice of redemption in accordance with Section 1104 of the Base Indenture and Section 3.03 of this Annex A of the Twelfth Supplemental Indenture to the Holders of Notes, a Holder of Notes may exchange Notes at any time prior to the close of business on the second Business Day immediately preceding the corresponding Redemption Date; provided, however, that a Holder who has already delivered a Fundamental Change Repurchase Notice with respect to a Note may not exchange such Note until the Holder has withdrawn the Fundamental Change Repurchase Notice in accordance with the terms of the Note and this Annex A of the Twelfth Supplemental Indenture.

(e) (i) In the event that the Company or Parent elects to:

(i) distribute to all or substantially all holders of Common Stock rights entitling them to purchase, for a period expiring within 60 days, shares of Common Stock at a price less than the Last Reported Sale Price of the Common Stock for the Trading Day immediately preceding the declaration date of such distribution; or

(ii) distribute to all or substantially all holders of Common Stock, assets or debt securities of the Company or Parent or rights to purchase the Company’s or Parent’s securities, which distribution has a per share value (as determined by the Board of Trustees) exceeding 15% of the Last Reported Sale Price of the Common Stock on the day immediately preceding the date of declaration of such distribution,

then, in either case, Holders may surrender the Notes for exchange at any time on and after the date that Parent provides notice to Holders referred to in the next sentence until the earlier of the close of business on the Business Day immediately preceding the Ex-Dividend Date for such distribution or the date Parent announces that such distribution will not take place. The Company shall notify Holders of any distribution referred to in either clause (A) or clause (B)

A-18

above and of the resulting exchange right no later than the 35th Business Day prior to the Ex-Dividend Date for such distribution.

(ii) If the Company is a party to any transaction or event that constitutes a Fundamental Change, a Holder may surrender Notes for exchange at any time from and after the 30th scheduled Trading Day prior to the anticipated Effective Date of such transaction or event until the related Fundamental Change Repurchase Date and, upon such surrender, the Holder shall be entitled to the increase in the Exchange Rate, if any, specified in Section 8.01(g). The Company shall give notice to all record Noteholders and the Trustee and issue a press release of the Fundamental Change no later than 30 scheduled Trading Days prior to the anticipated Effective Date of the Fundamental Change.

(iii) If Parent is a party to a consolidation, merger, binding share exchange or sale or conveyance of all or substantially all of its properties and assets, in each case pursuant to which the Common Stock would be exchanged into cash, securities and/or other property, then the Holders shall have the right to exchange Notes at any time beginning fifteen calendar days prior to the date announced by Parent as the anticipated effective date of the transaction and until and including the date that is fifteen calendar days after the date that is the effective date of such transaction; provided such transaction does not otherwise constitute a Fundamental Change to which the provisions of Section 8.01(e)(ii) shall apply. The Company shall give notice to all record Noteholders and the Trustee and issue a press release at least 20 calendar days prior to the anticipated effective date of such transaction. If the Board of Directors determines the anticipated effective date of the transaction, such determination shall be conclusive and binding on the Holders.

(f) The Notes shall be exchangeable at any time beginning on the first Business Day after any 30 consecutive Trading Day period during which the Common Stock is not listed on a U.S. national securities exchange.

(g) (i) If a Noteholder elects to exchange Notes in connection with a Fundamental Change that occurs prior to April 5, 2012, the Exchange Rate applicable to each $1,000 principal amount of Notes so exchanged shall be increased by an additional number of shares of Common Stock (the “Additional Shares”) as described below. Settlement of Notes tendered for exchange to which Additional Shares shall be added to the Exchange Rate as provided in this subsection shall be settled pursuant to Section 8.02 below, as applicable. For purposes of this Section 8.01(g), an exchange shall be deemed to be “in connection with” a Fundamental Change to the extent that the related exchange notice is delivered during the time period beginning on the 30th Trading Day prior to the anticipated Effective Date of such Fundamental Change and ending on the related Fundamental Change Repurchase Date, inclusive (regardless of whether the provisions of clauses (b), (c), (d), (e) or (f) of this Section 8.01 shall apply to such exchange). Such exchange notice shall indicate that the Holder of Notes has elected to exchange Notes in connection with a Fundamental Change; provided, however, that the failure to so indicate shall not in any way affect the Exchange Obligation or the right of such Holder to receive Additional Shares in connection with such exchange.

A-19

(ii) The number of Additional Shares by which the Exchange Rate will be increased shall be determined by reference to the table attached as Schedule A hereto, based on the date on which the Fundamental Change occurs or becomes effective (the “Effective Date”), and the Stock Price; provided, that if the Stock Price is between two Stock Price amounts in the table or the Effective Date is between two Effective Dates in the table, the number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the next higher and next lower Stock Price amounts and the two nearest Effective Dates, as applicable, based on a 365-day year; provided further that if (1) the Stock Price is greater than $380.82 per share of Common Stock (subject to adjustment in the same manner as set forth in Section 8.04), no Additional Shares will be added to the Exchange Rate, and (2) the Stock Price is less than $142.97 per share of Common Stock (subject to adjustment in the same manner as set forth in Section 8.04), no Additional Shares will be added to the Exchange Rate. Notwithstanding the foregoing, in no event will the total number of shares of Common Stock issuable upon exchange exceed 7.0410 per $1,000 principal amount of Notes (subject to adjustment in the same manner as set forth in Section 8.04).

(iii) The Stock Prices set forth in the first row of the table in Schedule A hereto shall be adjusted as of any date on which the Exchange Rate of the Notes is adjusted. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Exchange Rate in effect immediately prior to the adjustment giving rise to the Stock Price adjustment and the denominator of which is the Exchange Rate as so adjusted. The number of Additional Shares within the table shall be adjusted in the same manner as the Exchange Rate as set forth in Section 8.04 (other than by operation of an adjustment to the Exchange Rate by adding Additional Shares).

Section 8.02 Exchange Procedures.

(a) (1) The Company shall settle its Exchange Obligations as described in Section 8.02(a)(3), unless, within the applicable time period specified in this Section 8.02(a)(1), the Company elects to settle its Exchange Obligations as described in Section 8.02(a)(2) or Section 8.02(a)(4). The cash and/or shares of Common Stock which the Company is required to deliver in accordance with this Section 8.02 in settlement of its Exchange Obligations is referred to herein as the “Settlement Amount.” If the Company desires to settle its Exchange Obligations as described in Section 8.02(a)(2) or Section 8.02(a)(4), the Company shall notify each exchanging Noteholder by notice to the Trustee (for further distribution to Noteholders) of the method the Company will choose to satisfy its Exchange Obligations no later than the second Trading Day immediately following the Company’s receipt of a Notice of Exchange from such Holder, and such notice shall specify the section of this Annex A of the Twelfth Supplemental Indenture pursuant to which the Company is electing to satisfy its exchange obligations; provided, however, that the Company shall have the right to irrevocably elect, in its sole discretion and without the consent of Noteholders, by notice to the Trustee (for further distribution to Noteholders), on or prior to February 1, 2012, to settle all of its future Exchange Obligations entirely in shares of Common Stock as described in Section 8.02(a)(2), and provided further, that the Company is required to settle all exchanges with an Exchange Date occurring on or after February 1, 2012 in the same manner, and the Company shall notify Noteholders by

A-20

notice to the Trustee (for further distribution to Noteholders) of the manner of settlement (including specifying the applicable section of this Annex A of the Twelfth Supplemental Indenture that describes such manner of settlement) on or before such date. The Company shall treat all Noteholders exchanging on the same Trading Day in the same manner; however, the Company shall not have any obligation to settle its Exchange Obligations arising on different Trading Days in the same manner, except for exchanges with an Exchange Date occurring on or after February 1, 2012, which shall all be satisfied in the same manner.

(2) If the Company has elected, within the applicable time periods specified in Section 8.02(a)(1), to settle its Exchange Obligations as described in this Section 8.02(a)(2), the Company shall have the right to settle its Exchange Obligations entirely in shares of Common Stock. If the Company elects to satisfy its Exchange Obligation entirely in shares of Common Stock, the Company shall deliver a number of shares of Common Stock equal to (i) the aggregate principal amount of Notes to be exchanged divided by $1,000, multiplied by (ii) the applicable Exchange Rate (which shall include any increases to reflect any Additional Shares that such Holder is entitled to receive pursuant to Section 8.01(g) above). The Company shall deliver such shares of Common Stock as soon as practicable after it has notified the exchanging Holder pursuant to Section 8.02(a)(1) above, that it has elected to satisfy its Exchange Obligation entirely in shares of Common Stock.

(3) If the Company does not elect, within the applicable time periods specified in Section 8.02(a)(1), to settle its Exchange Obligations as described in Section 8.02(a)(2) or 8.02(a)(4), the Company shall settle its Exchange Obligations as described in this Section 8.02(a)(3), subject to Section 8.02(b) hereof. The Company shall deliver in respect of each $1,000 principal amount of Notes being exchanged a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the 20 consecutive Trading Days during the Observation Period, on the third Trading Day immediately following the last day of the related Observation Period; provided that the Company will deliver cash in lieu of fractional shares of Common Stock as set forth pursuant to clause (k) below. The Daily Settlement Amounts shall be determined by the Company promptly following the last day of the Observation Period.

A-21

Common Stock deliverable in respect of each Trading Day in the applicable Observation Period shall equal (i) the product of (y) 100% minus the cash percentage and (z) the amount by which the Daily Exchange Value exceeds $50 for such Trading Day, divided by (ii) the Daily VWAP of the Common Stock for such Trading Day. If the Company does not specify a cash percentage, it must settle the entire amount by which the Daily Exchange Value exceeds $50 with shares of Common Stock pursuant to Section 8.02(a)(3) above; provided, however, that the Company will deliver cash in lieu of fractional shares of Common Stock as set forth pursuant to clause (k) below. If the Company specifies a cash percentage, the Company shall satisfy its Exchange Obligation by delivering, on the third Trading Day immediately following the last day of the related Observation Period, the amount of cash and the number of shares of Common Stock deliverable pursuant to this Section 8.02(a)(4).

(b) Notwithstanding Section 8.02(a), the Company shall satisfy the Exchange Obligation with respect to each $1,000 principal amount of Notes tendered for exchange to which Additional Shares shall be added to the Exchange Rate as set forth in Section 8.01(g) pursuant to this clause (b).

(i) If the last day of the applicable Observation Period related to Notes surrendered for exchange is prior to the third Trading Day preceding the Effective Date of the Fundamental Change, the Company will satisfy the related Exchange Obligation with respect to each $1,000 principal amount of Notes tendered for exchange as described in Section 8.01(a) by delivering the amount of cash and shares of Common Stock, if any (based on the Exchange Rate, but without regard to the number of Additional Shares to be added to the Exchange Rate pursuant to Section 8.01(g)) on the third Trading Day immediately following the last day of the applicable Observation Period. In addition, as soon as practicable following the Effective Date of the Fundamental Change, the Company will deliver the increase in such amount of cash and Reference Property deliverable in lieu of shares of Common Stock, if any, as if the Exchange Rate had been increased by such number of Additional Shares during the related Observation Period (and based upon the related Daily VWAP prices during such Observation Period). If such increased amount of cash and Common Stock, if any, results in an increase to the amount of cash to be paid to Holders, the Company will pay such increase in cash, and if such increased amount results in an increase to the number of shares of Common Stock, the Company will deliver such increase by delivering Reference Property based on such increased number of shares.

(ii) If the last day of the applicable Observation Period related to Notes surrendered for exchange is on or following the third scheduled Trading Day preceding the Effective Date of such Fundamental Change, the Company will satisfy the Exchange Obligation with respect to each $1,000 principal amount of Notes tendered for exchange as described in Section 8.01(a) (based on the Exchange Rate as increased by the Additional Shares pursuant to Section 8.01(g) above) on the later to occur of (x) the Effective Date of the Fundamental Change and (y) the third Trading Day immediately following the last day of the applicable Observation Period.

A-22

(c) Before any Holder of a Note shall be entitled to exchange the same as set forth above, such Holder shall (1) in the case of a Global Note, comply with the procedures of the Depositary in effect at that time and, if required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 4.01(b) and Section 8.02(i) and, if required, pay all taxes or duties, if any, and (2) in the case of a Note issued in certificated form, (A) complete and manually sign and deliver an irrevocable written notice to the Exchange Agent in the form on the reverse of such certificated Note (or a facsimile thereof) (a “Notice of Exchange”) at the office of the Exchange Agent and shall state in writing therein the principal amount of Notes to be exchanged and the name or names (with addresses) in which such Holder wishes the certificate or certificates for any shares of Common Stock, if any, to be delivered upon settlement of the Exchange Obligation to be registered, (B) surrender such Notes, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer documents), at the office of the Exchange Agent, (C) if required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 4.01(b) and Section 8.02(i), and (D) if required, pay all taxes or duties, if any. A Note shall be deemed to have been exchanged immediately prior to the close of business on the date (the “Exchange Date”) that the Holder has complied with the requirements set forth in this Section 8.02(c).

No Notice of Exchange with respect to any Notes may be tendered by a Holder thereof if such Holder has also tendered a Put Right Repurchase Notice or a Fundamental Change Repurchase Notice and not validly withdrawn such Put Right Repurchase Notice or Fundamental Change Repurchase Notice in accordance with the applicable provisions of Section 9.01 or 9.02, as the case may be.

If more than one Note shall be surrendered for exchange at one time by the same Holder, the Exchange Obligation with respect to such Notes, if any, that shall be payable upon exchange shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted thereby) so surrendered.

(d) Delivery of the amounts owing in satisfaction of the Exchange Obligation shall be made by the Company in no event later than the date specified in Section 8.02(a), except to the extent specified in Section 8.02(b). The Company shall make such delivery by paying the cash amount owed to the Exchange Agent or to the Holder of the Note surrendered for exchange, or such Holder’s nominee or nominees, and by issuing, or causing to be issued, and delivering to the Exchange Agent or to such Holder, or such Holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the number of full shares of Common Stock to which such Holder shall be entitled as part of such Exchange Obligation (together with any cash in lieu of fractional shares).

(e) In case any Note shall be surrendered for partial exchange, 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 unexchanged portion of the surrendered Notes.

A-23

(f) If a Holder submits a Note for exchange, the Company shall pay all stamp and other duties, if any, which may be imposed by the United States or any political subdivision thereof or taxing authority thereof or therein with respect to the issuance of shares of Common Stock, if any, upon the exchange. However, the Holder shall pay any such tax that is due because the Holder requests any shares of Common Stock to be issued in a name other than the Holder’s name. The Exchange Agent may refuse to deliver the certificates representing the shares of Common Stock being issued in a name other than the Holder’s name until the Trustee receives a sum sufficient to pay any tax which will be due because the shares are to be issued in a name other than the Holder’s name. Nothing herein shall preclude any tax withholding required by law or regulations.

(g) Except as provided in Section 8.04, no adjustment shall be made for dividends on any shares issued upon the exchange of any Note as provided in this Article.

(h) Upon the exchange of an interest in a Global Note, the Trustee, or the Custodian at the direction of the Trustee, shall make a notation on such Global Note as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any exchange of Notes effected through any Exchange Agent other than the Trustee.

(i) Upon exchange, a Noteholder will not receive any separate cash payment for accrued and unpaid interest, except as set forth below. The Company’s settlement of its Exchange Obligation as described above shall be deemed to satisfy its obligation to pay the principal amount of the Note and accrued and unpaid interest to, but not including, the Exchange Date. As a result, accrued and unpaid interest to, but not including, the Exchange Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Notwithstanding the preceding sentence, if Notes are exchanged after the close of business on a Record Date, Holders of such Notes as of the close of business on the Record Date will receive the interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the exchange. Notes surrendered for exchange during the period from the close of business on any regular Record Date to the opening of business on the corresponding Interest Payment Date must be accompanied by payment of an amount equal to the interest payable on the Notes so exchanged; provided, however, that no such payment need be made (1) if the Company has called the Notes for redemption or (2) to the extent of any overdue interest existing at the time of exchange with respect to such Note, (3) to Notes surrendered for exchange in connection with a Fundamental Change in which the Company has specified a Fundamental Change Repurchase Date that is after a Record Date and on or prior to the next Interest Payment Date, or (4) to Notes surrendered for exchange after the Record Date immediately preceding the Maturity Date. Except as described above, no payment or adjustment will be made for accrued interest on exchanged Notes.

A-24

holder or holders thereof for all purposes at the close of business on the next succeeding day on which such stock transfer books are open; such exchange shall be at the Exchange Rate in effect on the date that such Notes shall have been surrendered for exchange, as if the stock transfer books of the Company had not been closed. Upon exchange of Notes, such Person shall no longer be a Noteholder.

(k) No fractional shares of Common Stock shall be issued upon exchange of any Note or Notes. If more than one Note shall be surrendered for exchange at one time by the same Holder, the number of full shares that shall be issued upon exchange thereof shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof) so surrendered. Instead of any fractional share of Common Stock that would otherwise be issued upon exchange of any Note or Notes (or specified portions thereof), the Company shall pay a cash adjustment in respect of such fraction (calculated to the nearest one-100th of a share) in an amount equal to the same fraction of the Last Reported Sale Price of the Common Stock on the last day of the applicable Observation Period.

Section 8.03 Reserved.

Section 8.04 Adjustment of Exchange Rate. The Exchange Rate shall be adjusted from time to time by the Company as follows:

(a) In case Parent shall issue Common Stock as a dividend or distribution to holders of the outstanding Common Stock, or shall effect a subdivision into a greater number of shares of Common Stock or combination into a lesser number of shares of Common Stock, the Exchange Rate shall be adjusted based on the following formula:

where

ER₀ = the Exchange Rate in effect immediately prior to such event;

ER' = the Exchange Rate in effect immediately after such event;

OS₀ = the number of shares of Common Stock outstanding immediately prior to such event; and

OS' = the number of shares of Common Stock outstanding immediately after such event.

Such adjustment shall become effective immediately after 9:00 a.m., New York City time, on the Business Day following the record date fixed for such determination. If any dividend or distribution of the type described in this Section 8.04(a) is declared but not so paid or made, or the outstanding shares of Common Stock are not subdivided or combined, as the case may be, the Exchange Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, or subdivide or combine the

A-25

outstanding shares of Common Stock, as the case may be, to the Exchange Rate that would then be in effect if such dividend, distribution, subdivision or combination had not been declared.

(b) In case Parent shall issue to all or substantially all holders of its outstanding Common Stock any rights, warrants or convertible securities entitling them (for a period expiring within sixty (60) calendar days after the issuance thereof) to subscribe for or purchase shares of Common Stock at a price per share less than the Last Reported Sale Price of the Common Stock on the Business Day immediately preceding the date of announcement of such issuance, the Exchange Rate shall be adjusted based on the following formula:


where

ER₀ =		the Exchange Rate in effect immediately prior to such event;

ER' =		the Exchange Rate in effect immediately after such event;

OS₀ =		the number of shares of Common Stock outstanding immediately prior to such event;

X =		the total number of shares of Common Stock issuable pursuant to such rights, warrants or convertible securities; and

Y =		the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, warrants or convertible securities divided by the average of the Last Reported Sale Prices per share of Common Stock over the ten consecutive Trading Day period ending on the Business Day immediately preceding the record date (or, if later, the Ex-Date relating to such distribution) for the issuance of such rights, warrants or convertible securities.

Such adjustment shall be successively made whenever any such rights, warrants or convertible securities are issued and shall become effective immediately after 9:00 a.m., New York City time, on the Business Day following the date fixed for such determination. If such rights, warrants or convertible securities are not so exercised prior to their expiration, the Exchange Rate shall again be adjusted to be the Exchange Rate that would then be in effect if such record date for such distribution had not been fixed.

In determining whether any rights, warrants or convertible securities entitle the holder thereof to subscribe for or purchase shares of Common Stock at a price per share less than the Last Reported Sale Price of the Common Stock on the Business Day immediately preceding the date of announcement of such issuance, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received by Parent for such rights, warrants or convertible securities and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Trustees.

A-26

(c) In case Parent shall distribute to all or substantially all holders of its Common Stock shares of Capital Stock, evidences of its indebtedness or other assets or property of Parent (including securities, but excluding dividends and distributions covered by Section 8.04(a), Section 8.04(b) or Section 8.04(d) and distributions described below in this paragraph (c) with respect to Spin-Offs) (any of such shares of Capital Stock, indebtedness, or other asset or property hereinafter in this Section 8.04(c) called the “Distributed Property”), then, in each such case the Exchange Rate shall be adjusted based on the following formula:


where

ER₀ =		the Exchange Rate in effect immediately prior to such distribution;

ER' =		the Exchange Rate in effect immediately after such distribution;

SP₀ =		the average of the Last Reported Sale Prices of the Common Stock over the ten consecutive Trading Day period ending on the Business Day immediately preceding the record date for such distribution (or, if earlier, the Ex-Date relating to such distribution); and

FMV =		the fair market value (as determined by the Board of Trustees) of the Distributed Property distributed with respect to each outstanding share of Common Stock on the record date for such distribution (or, if earlier, the Ex-Date relating to such distribution).

Such adjustment shall become effective immediately prior to 9:00 a.m., New York City time, on the Business Day following the date fixed for the determination of stockholders entitled to receive such distribution; provided that if the then fair market value (as so determined) of the portion of the Distributed Property so distributed applicable to one share of Common Stock is equal to or greater than SP0 as set forth above, in lieu of the foregoing adjustment, adequate provision shall be made so that each Noteholder shall have the right to receive, for each $1,000 principal amount of Notes upon exchange, the amount of Distributed Property such Holder would have received had such Holder owned a number of shares of Common Stock equal to the Exchange Rate on the record date. If such dividend or distribution is not so paid or made, the Exchange Rate shall again be adjusted to be the Exchange Rate that would then be in effect if such dividend or distribution had not been declared. If the Board of Trustees determines the fair market value of any distribution for purposes of this Section 8.04(c) by reference to the actual or when issued trading market for any securities, it must in doing so consider the prices in such market over the same period used in determining SP₀ above.

With respect to an adjustment pursuant to this Section 8.04(c) where there has been a payment of a dividend or other distribution on the Common Stock in shares of Capital Stock, or similar equity interest, of or relating to a Subsidiary or other business unit (a “Spin-Off”), unless the Company distributes such shares of Capital Stock or equity interests to each Noteholder on the same basis as such Noteholder would have received had it exchanged its Notes solely into shares of Common Stock immediately prior to such dividend or distribution, the Exchange Rate

A-27

in effect immediately before 5:00 p.m., New York City time, on the Record Date fixed for determination of stockholders entitled to receive the distribution will be increased based on the following formula:


where

ER₀ =		the Exchange Rate in effect immediately prior to such distribution;

ER' =		the Exchange Rate in effect immediately after such distribution;

FMV₀ =		the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of shares of Common Stock applicable to one share of Common Stock over the first ten consecutive Trading Day period after the effective date of the Spin-Off; and

MP₀ =		the average of the Last Reported Sale Prices of the Common Stock over the first ten consecutive Trading Day period after the effective date of the Spin-Off.

Such adjustment shall occur on the tenth Trading Day from, and including, the effective date of the Spin-Off; provided that in respect of any exchange within the ten Trading Days following any Spin-Off, references within this paragraph (c) to ten days shall be deemed replaced with such lesser number of Trading Days as have elapsed between such Spin-Off and the Exchange Date in determining the applicable Exchange Rate.

Rights or warrants distributed by Parent to all holders of Common Stock, entitling the holders thereof to subscribe for or purchase shares of Common Stock (either initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such shares of Common Stock; (ii) are not exercisable and (iii) are also issued in respect of future issuances of shares of Common Stock, shall be deemed not to have been distributed for purposes of this Section 8.04 (and no adjustment to the Exchange Rate under this Section 8.04 will be required) until the occurrence of the earliest Trigger Event, whereupon such rights and warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Exchange Rate shall be made under this Section 8.04(c). If any such right or warrant, including any such existing rights or warrants distributed prior to the date of this Annex A of the Twelfth Supplemental Indenture, are subject to events, upon the occurrence of which such rights or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and record date with respect to new rights or warrants with such rights (and a termination or expiration of the existing rights or warrants without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Exchange Rate under this Section 8.04 was made, (1) in the case of any such rights or warrants that shall all have been redeemed or repurchased without exercise by any

A-28

holders thereof, the Exchange Rate shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder or holders of Common Stock with respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights or warrants that shall have expired or been terminated without exercise by any holders thereof, the Exchange Rate shall be readjusted as if such rights and warrants had not been issued.

For purposes of this Section 8.04(c), Section 8.04(a) and Section 8.04(b), any dividend or distribution to which this Section 8.04(c) is applicable that also includes shares of Common Stock to which Section 8.04(a) applies or rights or warrants to subscribe for or purchase shares of Common Stock to which Section 8.04(a) or Section 8.04(b) applies (or both), shall be deemed instead to be (1) a dividend or distribution of the evidences of indebtedness, assets or shares of Capital Stock other than such shares of Common Stock or rights or warrants to which Section 8.04(c) applies (and any Exchange Rate adjustment required by this Section 8.04(c) with respect to such dividend or distribution shall then be made) immediately followed by (2) a dividend or distribution of such shares of Common Stock or such rights or warrants (and any further Exchange Rate adjustment required by Section 8.04(a) and Section 8.04(b) with respect to such dividend or distribution shall then be made), except (A) the record date of such dividend or distribution shall be substituted as “the record date” and “the date fixed for such determination” within the meaning of Section 8.04(a) and Section 8.04(b) and (B) any shares of Common Stock included in such dividend or distribution shall not be deemed “outstanding immediately prior to such event” within the meaning of Section 8.04(a).

(d) In case Parent shall pay a dividend or make a distribution consisting exclusively of cash to all or substantially all holders of its Common Stock to the extent that the aggregate of all such cash dividends or distributions paid in any quarter exceeds the Dividend Threshold Amount for such quarter, the Exchange Rate shall be adjusted based on the following formula:


where

ER₀ =		the Exchange Rate in effect immediately prior to the record date for such distribution;

ER' =		the Exchange Rate in effect immediately after the record date for such distribution;

SP₀ =		the average of the Last Reported Sale Prices of the Common Stock over the period of ten consecutive Trading Days ending the Business Day immediately preceding the record date (as defined in clause (f) of this Section) for such distribution (or, if earlier, the Ex-Date relating to such distribution);

T =		the dividend threshold amount (“Dividend Threshold Amount”), which amount shall initially be $1.0305 per quarter and which shall be appropriately adjusted from time to

A-29


		time for any stock dividends on, or subdivisions or combinations of, Common Stock; provided, that if an Exchange Rate adjustment is required to be made as a result of a distribution that is not a quarterly dividend either in whole or in part, the Dividend Threshold Amount shall be deemed to be zero; and

C =		the amount in cash per share that Parent distributes to holders of Common Stock.

Such adjustment shall become effective immediately after 5:00 p.m., New York City time, on the record date for such dividend or distribution; provided that if the portion of the cash so distributed applicable to one share of Common Stock is equal to or greater than SP0 above, in lieu of the foregoing adjustment, adequate provision shall be made so that each Noteholder shall have the right to receive upon exchange of a Note (or any portion thereof) the amount of cash such Holder would have received had such Holder owned a number of shares equal to the Exchange Rate on the record date. If such dividend or distribution is not so paid or made, the Exchange Rate shall again be adjusted to be the Exchange Rate that would then be in effect if such dividend or distribution had not been declared.

For the avoidance of doubt, for purposes of this Section 8.04(d), in the event of any reclassification of the Common Stock, as a result of which the Notes become exchangeable into more than one class of Common Stock, if an adjustment to the Exchange Rate is required pursuant to this Section 8.04(d), references in this Section to one share of Common Stock or Last Reported Sale Price of one share of Common Stock shall be deemed to refer to a unit or to the price of a unit consisting of the number of shares of each class of Common Stock into which the Notes are then exchangeable equal to the number of shares of such class issued in respect of one share of Common Stock in such reclassification. The above provisions of this paragraph shall similarly apply to successive reclassifications.

(e) In case Parent or any of its Subsidiaries makes a payment in respect of a tender offer or exchange offer for all or any portion of the shares of Common Stock, to the extent that the cash and value of any other consideration included in the payment per share of Common Stock exceeds the Last Reported Sale Price of the Common Stock on the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer (as it may be amended), the Exchange Rate shall be increased based on the following formula:


where

ER₀ =		the Exchange Rate in effect on the date such tender or exchange offer expires;

ER' =		the Exchange Rate in effect on the day next succeeding the date such tender or exchange offer expires;

AC =		the aggregate value of all cash and any other consideration (as determined by the Board of Trustees) paid or payable for shares purchased in such tender or exchange offer;

A-30


OS₀ =		the number of shares of Common Stock outstanding immediately prior to the date such tender or exchange offer expires;

OS' =		the number of shares of Common Stock outstanding immediately after the date such tender or exchange offer expires; and

SP' =		the average of the Last Reported Sale Prices of the Common Stock over the ten consecutive Trading Day period commencing on the Trading Day next succeeding the date such tender or exchange offer expires,

such adjustment to become effective immediately prior to the opening of business on the day following the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer. If Parent is obligated to purchase shares pursuant to any such tender or exchange offer, but Parent is permanently prevented by applicable law from effecting all or any such purchases or all or any portion of such purchases are rescinded, the Exchange Rate shall again be adjusted to be the Exchange Rate that would then be in effect if such tender or exchange offer had not been made or had only been made in respect of the purchases that had been effected. No adjustment to the Exchange Rate will be made if the application of the foregoing formulae would result in a decrease in the Exchange Rate.

(f) For purposes of this Section 8.04 the term “record date” shall mean, with respect to any dividend, distribution or other transaction or event in which the holders of Common Stock have the right to receive any cash, securities or other property or in which the shares of Common Stock (or other applicable securities) are exchanged for or converted into any combination of cash, securities or other property, the date fixed for determination of stockholders entitled to receive such cash, securities or other property (whether such date is fixed by the Board of Directors or by statute, contract or otherwise).

(g) In addition to those required by clauses (a), (b), (c), (d), and (e) of this Section 8.04, and to the extent permitted by applicable law and subject to the applicable rules of the New York Stock Exchange, the Company from time to time may increase the Exchange Rate by any amount for a period of at least 20 days if the Board of Trustees determines that such increase would be in the Company’s best interest. In addition, the Company may also (but is not required to) increase the Exchange Rate to avoid or diminish any income tax to holders of Common Stock or rights to purchase shares of Common Stock in connection with any dividend or distribution of shares (or rights to acquire shares) or similar event. Whenever the Exchange Rate is increased pursuant to the preceding sentence, the Company shall mail to the Holder of each Note at his last address appearing on the Security Register a notice of the increase at least five days prior to the date the increased Exchange Rate takes effect, and such notice shall state the increased Exchange Rate and the period during which it will be in effect.

made to the Exchange Rate unless such adjustment would require a change of at least 1% in the Exchange Rate then in effect at such time. The Company shall carry forward any adjustments that are less than 1% of the Exchange Rate and make such carried forward adjustments, regardless of whether the aggregate adjustment is less than 1% within one year of the first such adjustment carried forward, upon a Fundamental Change, upon any call of the Notes for redemption or upon maturity.

(i) Whenever the Exchange Rate is adjusted as herein provided, the Company shall promptly 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. The Trustee and Exchange Agent may conclusively rely on the accuracy of the Exchange Rate adjustment provided by the Company. Unless and until a Responsible Officer of the Trustee shall have received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Exchange Rate and may assume without inquiry that the last Exchange Rate of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company 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 Holder of each Note at his last address appearing on the Security Register, within thirty (30) days of the effective date of such adjustment. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

(j) For purposes of this Section 8.04, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of Parent but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock.

Section 8.05 Sufficient Shares to be Delivered. To the extent the Company elects to deliver shares of Common Stock, and subject to Section 8.02(k), the Company shall provide, free from preemptive rights, sufficient shares of Common Stock to provide for exchange of the Notes from time to time as such Notes are presented for exchange.

Section 8.06 Effect of Reclassification, Consolidation, Merger or Sale. If any of the following events occur, namely (i) any reclassification or change of the outstanding Common Stock (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a split, subdivision or combination), (ii) any consolidation, merger or combination of Parent with another Person, or (iii) any sale or conveyance of all or substantially all of the property and assets of Parent to any other Person, in either case as a result of which holders of Common Stock shall be entitled to receive cash, securities or other property or assets with respect to or in exchange for such shares of Common Stock (any such event a “Merger Event”), then:

(a) the Company, or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture (which, as evidenced in an Opinion of Counsel delivered to the Trustee, shall comply with the Trust Indenture Act as in force at the date of execution of such supplemental indenture if such supplemental indenture is then required to so comply) providing for the exchange and settlement of the Notes as set forth in this Annex A

A-32

of the Twelfth Supplemental Indenture. Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article and the Trustee may conclusively rely on the determination by the Company of the equivalency of such adjustments. If, in the case of any Merger Event, the Reference Property includes shares of stock or other securities and assets of a corporation other than the successor or purchasing corporation, as the case may be, in such reclassification, change, consolidation, merger, combination, sale or conveyance, then such supplemental indenture shall also be executed by such other corporation and shall contain such additional provisions to protect the interests of the Holders of the Notes as the Board of Trustees shall reasonably consider necessary by reason of the foregoing, including to the extent required by the Board of Trustees and practicable the provisions providing for the repurchase rights set forth in Article IX herein.

In the event the Company shall execute a supplemental indenture pursuant to this Section 8.06, the Company shall, in addition to the Officers’ Certificate and Opinion of Counsel required by Section 102 of the Base Indenture, file with the Trustee an Officers’ Certificate briefly stating the kind or amount of cash, securities or property or asset that will constitute the Reference Property after any such Merger Event, any adjustment to be made with respect thereto, and the Trustee shall promptly mail notice thereof to all Noteholders.

(b) Notwithstanding the provisions of Section 8.02(a) and Section 8.02(b), and subject to the provisions of Section 8.01, at the effective time of such Merger Event, the right to exchange each $1,000 principal amount of Notes will be changed to a right to exchange such Note by reference to the kind and amount of cash, securities or other property or assets that a holder of a number of shares of Common Stock equal to the Exchange Rate immediately prior to such transaction would have owned or been entitled to receive (the “Reference Property”) such that from and after the effective time of such transaction, a Noteholder will be entitled thereafter to exchange its Notes, subject to the successor’s right to deliver cash, shares of Common Stock or common stock of such successor or a combination of cash and shares of Common Stock as set forth in Section 8.02(b), into cash (up to the aggregate principal amount thereof) and, in lieu of the shares of Common Stock otherwise deliverable, the same type (and in the same proportion) of Reference Property, based on the Daily Settlement Amounts of Reference Property in an amount equal to the applicable Exchange Rate, as described under Section 8.02(b). For purposes of determining the constitution of Reference Property, the type and amount of consideration that a holder of Common Stock would have been entitled to in the case of reclassifications, consolidations, mergers, sales or conveyance of assets or other transactions that cause the Common Stock to be converted into the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election) will be deemed to be the weighted average of the types and amounts of consideration received by the holders of shares of Common Stock that affirmatively make such an election. Parent shall not become a party to any such transaction unless its terms are consistent with the preceding. None of the foregoing provisions shall affect the right of a Holder of Notes to exchange its Notes in accordance with the provisions of Article VIII hereof prior to the effective date.

(c) The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Noteholder, at his address appearing on the Security Register,

A-33

within thirty (30) days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture.

(d) The above provisions of this Section shall similarly apply to successive Merger Events.

Section 8.07 Certain Covenants. The Company covenants that all shares of Common Stock delivered upon exchange of Notes will be fully paid and non-assessable by Parent and free from all taxes, liens and charges with respect to the issue thereof.

Section 8.08 Responsibility of Trustee. The Trustee and any other Exchange Agent shall not at any time be under any duty or responsibility to any Noteholder to determine the Exchange Rate or whether any facts exist which may require any adjustment of the Exchange Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other Exchange Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities or property, which may at any time be issued or delivered upon the exchange of any Note; and the Trustee and any other Exchange Agent make no representations with respect thereto. Neither the Trustee nor any Exchange Agent shall be responsible for any failure of the Company to transfer or deliver any shares of Common Stock or share certificates or other securities or property or cash upon the surrender of any Note for the purpose of exchange or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article.

Without limiting the generality of the foregoing, neither the Trustee nor any Exchange Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 8.06 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Noteholders upon the exchange of their Notes after any event referred to in such Section 8.06 or to any adjustment to be made with respect thereto, but, subject to the provisions of Article Six of the Base Indenture, may accept as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officers’ Certificate with respect thereto.

Section 8.09 Notice to Holders Prior to Certain Actions.

In case:

(a) Parent shall declare a dividend (or any other distribution) on its Common Stock that would require an adjustment in the Exchange Rate pursuant to Section 8.04; or

(b) Parent shall authorize the granting to all of the holders of its Common Stock of rights or warrants to subscribe for or purchase any share of any class or any other rights or warrants;

(c) of any reclassification of the Common Stock of Parent (other than a subdivision or combination of its outstanding Common Stock, or a change in par value, or from par value to no par value, or from no par value to par value), or of any consolidation or merger to

A-34

which Parent is a party and for which approval of any stockholders of Parent is required, or of the sale or transfer of all or substantially all of the assets of Parent; or

(d) of the voluntary or involuntary dissolution, liquidation or winding-up of Parent,

the Company shall cause to be filed with the Trustee and to be mailed to each Noteholder at his address appearing on the Security Register as promptly as possible but in any event at least thirty (30) days prior to the applicable date specified in clause (x) or (y) below, as the case may be, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution or rights or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution or rights are to be determined, or (y) the date on which such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities or other property deliverable upon such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such dividend, distribution, reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up.

Section 8.10 Stockholder Rights Plans. Upon exchange of the Notes, the Holders shall receive, in addition to any shares of Common Stock issuable upon such exchange, the associated rights issued under any future stockholder rights plan Parent adopts unless, prior to exchange, the rights have separated from the shares of Common Stock, expired, terminated or been redeemed or converted in accordance with such rights plan. If, and only if, the Holders receive rights under such stockholder rights plans as described in the preceding sentence upon exchange of their Notes, then no other adjustment pursuant to this Article VIII shall be made in connection with such stockholder rights plans.

Section 8.11 Ownership Limit. Notwithstanding any other provision of this Annex A of the Twelfth Supplemental Indenture or the Notes, no Holder of Notes (or beneficial owner of Notes) shall be entitled to exchange such Notes for shares of Common Stock to the extent that receipt of such shares would cause such Holder (or beneficial owner of Notes) (together with such Holder’s (or beneficial owner’s) affiliates) to exceed the applicable ownership limit contained in the articles of incorporation of Parent.

ARTICLE IX

Section 9.01 Repurchase of Securities at Option of the Holder on Specified Dates.

$1,000 principal amount, for cash on April 1, 2012, April 1, 2017, April 1, 2022, April 1, 2027 and April 1, 2032 (each, a “Put Right Repurchase Date”) at a repurchase price per Note equal to 100% of the aggregate principal amount of the Notes being repurchased, together with any accrued and unpaid interest up to, but not including, such Put Right Repurchase Date (the “Put Right Repurchase Price”).

Repurchases of Notes by the Company pursuant to this Section 9.01 shall be made, at the option of the Holder thereof, upon:

(A) delivery to the Trustee (or other Paying Agent appointed by the Company) by the Holder of a written notice of purchase (a “Put Right Repurchase Notice”) in the form set forth on the reverse of the Note at any time from the opening of business on the date that is 25 Business Days prior to the applicable Put Right Repurchase Date until the close of business on the fifth Business Day prior to such Put Right Repurchase Date stating:

The Company shall repurchase from the Holder thereof, pursuant to this Section 9.01, a portion of a Note if the principal amount of such portion is $1,000 or an integral multiple of $1,000. Provisions of this Annex A of the Twelfth Supplemental Indenture that apply to the repurchase of all of a Note also apply to the repurchase of such portion of such Note.

Any repurchase by the Company contemplated pursuant to the provisions of this Section 9.01 shall be consummated by the delivery of the consideration to be received by the Holder promptly following the later of the Put Right Repurchase Date and the time of delivery of the Note.

The Trustee (or other Paying Agent appointed by the Company) shall promptly notify the Company of the receipt by it of any Put Right Repurchase Notice or written notice of withdrawal thereof in accordance with the provisions of Section 9.01(e).

A-36

Any Note that is to be repurchased only in part shall be surrendered to the Trustee (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and make available for delivery to the Holder of such Note without service charge, a new Note or Notes, containing identical terms and conditions, each in an authorized denomination in aggregate principal amount equal to and in exchange for the unrepurchased portion of the principal of the Note so surrendered.

(c) In connection with any purchase of Notes pursuant to this Section 9.01, the Company shall give written notice of the Put Right Repurchase Date to the Holders (the “Company Put Right Notice”).

The Company Put Right Notice shall be sent by first-class mail to the Trustee and to each Holder (and to each beneficial owner as required by applicable law) that has delivered a Put Right Repurchase Notice within ten Business Days of receipt of such Put Right Repurchase Notice, or, if a shorter period, at least two Business Days prior to any Put Right Repurchase Date (the “Company Put Right Notice Date”). Each Company Put Right Notice shall include a form of Put Right Repurchase Notice to be completed by a Noteholder and shall state:

(A) the Put Right Repurchase Price and the Exchange Price;

(B) the name and address of the Paying Agent and the Exchange Agent;

A-37

(J) the CUSIP number of the Notes.

If any of the Notes are to be redeemed in the form of a Global Note, the Company shall modify such notice to the extent necessary to accord with the procedures of the Depositary applicable to redemptions.

At the Company’s request, the Trustee shall give such Company Put Right Notice in the Company’s name and at the Company’s expense; provided, however, that, in all cases, the text of such Company Put Right Notice shall be prepared by the Company.

(d) Upon receipt by the Trustee (or other Paying Agent appointed by the Company) of the Put Right Repurchase Notice specified in Section 9.01(a), the Holder of the Note in respect of which such Put Right Repurchase Notice was given shall (unless such Put Right Repurchase Notice is withdrawn as specified in Section 9.01(e)) thereafter be entitled to receive solely the Put Right Repurchase Price with respect to such Note. Such Put Right Repurchase Price shall be paid to such Holder, subject to receipt of funds by the Paying Agent, promptly following the later of (x) the Put Right Repurchase Date with respect to such Note (provided the conditions in Section 9.01(a) have been satisfied) and (y) the time of delivery of such Note to the Paying Agent by the Holder thereof in the manner required by Section 9.01(a). Notes in respect of which a Put Right Repurchase Notice has been given by the Holder thereof may not be exchanged pursuant to Article VIII hereof on or after the date of the delivery of such Put Right Repurchase Notice, unless such Put Right Repurchase Notice has first been validly withdrawn as specified in Section 9.01(e).

(e) A Put Right Repurchase Notice may be withdrawn by means of a written notice of withdrawal delivered to the office of the Paying Agent in accordance with the Put Right Repurchase Notice at any time prior to 10:00 A.M.

provided, however, that if the Notes are not in certificated form, the notice must comply with appropriate procedures of the Depositary.

A written notice of withdrawal of a Put Right Repurchase Notice shall be in the form set forth in the preceding paragraph.

Upon receipt of a written notice of withdrawal, the Paying Agent shall promptly return to the Holders thereof any Notes in respect of which a Put Right Repurchase Notice has been withdrawn in accordance with the provisions of Section 9.01(f).

A-38

(f) There shall be no repurchase of any Notes pursuant to this Section 9.01 if there has occurred (prior to, on or after, as the case may be, the giving, by the Holders of such Notes, of the required Put Right Repurchase Notice) and is continuing an Event of Default with respect to Notes (other than a default in the payment of the Put Right Repurchase Price with respect to such Notes). The Paying Agent will promptly return to the respective Holders thereof any Notes held by it during the continuance of an Event of Default with respect to Notes (other than a default in the payment of the Put Right Repurchase Price with respect to such Notes), in which case, upon such return, the Put Right Repurchase Notice with respect thereto shall be deemed to have been withdrawn.

(g) Prior to 11:00 a.m. (local time in The City of New York) on the Put Right Repurchase Date, the Company shall deposit with the Trustee (or other Paying Agent appointed by the Company or if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust in accordance with the terms of the Base Indenture as modified by this Annex A of the Twelfth Supplemental Indenture) an amount (in immediately available funds if deposited on such Business Day) sufficient to pay the aggregate Put Right Repurchase Price of all the Notes or portions thereof which are to be purchased as of the Put Right Repurchase Date. The manner in which the deposit required by this Section 9.01(g) is made by the Company shall be at the option of the Company; provided that such deposit shall be made in a manner such that the Trustee or a Paying Agent shall have immediately available funds on the Put Right Repurchase Date.

If the Trustee (or other Paying Agent appointed by the Company) holds, in accordance with the terms hereof, money sufficient to pay the Put Right Repurchase Price of any Note, then, on the Put Right Repurchase Date, such Note will cease to be Outstanding and the rights of the Holder in respect thereof shall terminate (other than the right to receive the Put Right Repurchase Price as aforesaid).

To the extent that the aggregate amount of cash deposited by the Company pursuant to this Section 9.01(g) exceeds the aggregate Put Right Repurchase Price of the Notes or portions thereof that the Company is obligated to purchase, then promptly after the Put Right Repurchase Date the Trustee or a Paying Agent, as the case may be, shall return any such excess cash to the Company.

Section 9.02 Repurchase at Option of Holders Upon a Fundamental Change.

(a) If a Fundamental Change occurs at any time, then each Noteholder shall have the right, at such Holder’s option, to require the Company to repurchase all of such Holder’s Notes or any portion thereof that is a multiple of $1,000 principal amount, for cash on the date (the “Fundamental Change Repurchase Date”) specified by the Company that is not less than twenty (20) Business Days and not more than thirty-five (35) Business Days after the date of the Fundamental Change Company Notice (as defined below) at a repurchase price equal to 100% of the principal amount thereof, together with accrued and unpaid interest thereon to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”).

Repurchases of Notes under this Section 9.02 shall be made, at the option of the Holder thereof, upon:

A-39

(A) delivery to the Trustee (or other Paying Agent appointed by the Company) by a Holder of a duly completed notice (the “Fundamental Change Repurchase Notice”) in the form set forth on the reverse of the Note prior to the close of business on the Fundamental Change Repurchase Date; and

The Fundamental Change Repurchase Notice shall state:

(A) if certificated, the certificate numbers of Notes to be delivered for repurchase;

(B) the portion of the principal amount of Notes to be repurchased, which must be $1,000 or an integral multiple thereof; and

Any repurchase by the Company contemplated pursuant to the provisions of this Section 9.02 shall be consummated by the delivery of the consideration to be received by the Holder promptly following the later of the Fundamental Change Repurchase Date and the time of the book-entry transfer or delivery of the Note.

The Trustee (or other Paying Agent appointed by the Company) shall promptly notify the Company of the receipt by it of any Fundamental Change Repurchase Notice or written notice of withdrawal thereof in accordance with the provisions of Section 9.02(c).

(b) On or before the twentieth day after the occurrence of any Fundamental Change, the Company shall provide to all Holders of record of the Notes and the Trustee and

A-40

Paying Agent a notice (the “Fundamental Change Company Notice”) of the occurrence of such Fundamental Change and of the repurchase right at the option of the Holders arising as a result thereof. Such mailing shall be by first class mail. Simultaneously with providing such Fundamental Change Company Notice, the Company shall publish a notice containing the information included therein once in a newspaper of general circulation in The City of New York or publish such information on the Company’s website or through such other public medium as the Company may use at such time.

Each Fundamental Change Company Notice shall specify:

(A) the events causing the Fundamental Change;

(B) the date of the Fundamental Change;

(C) that the Holder must exercise the repurchase right on or prior to the close of business on the Fundamental Change Repurchase Date;

(D) the Fundamental Change Repurchase Price;

(I) the procedures that Holders must follow to require the Company to repurchase their Notes.

No failure of the Company to give the foregoing notices and no defect therein shall limit the Noteholders’ repurchase rights or affect the validity of the proceedings for the repurchase of the Notes pursuant to this Section 9.02.

(c) A Fundamental Change Repurchase Notice may be withdrawn by means of a written notice of withdrawal delivered to the Trustee and Paying Agent in accordance with the Fundamental Change Company Notice at any time prior to the close of business on the Business Day prior to the Fundamental Change Repurchase Date, specifying:

(A) the principal amount of the Notes with respect to which such notice of withdrawal is being submitted;

(B) if certificated Notes have been issued, the certificate numbers of the withdrawn Notes; and

A-41

(C) the principal amount, if any, of such Notes that remains subject to the original Fundamental Change Repurchase Notice, which portion must be in principal amounts of $1,000 or an integral multiple of $1,000;

provided, however, that if the Notes are not in certificated form, the notice must comply with appropriate procedures of the Depositary.

(d) On or prior to 11:00 a.m. (local time in The City of New York) on the second Business Day following the Fundamental Change Repurchase Date, the Company will deposit with the Trustee (or other Paying Agent appointed by the Company or if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust in accordance with the Base Indenture as modified by this Annex A of the Twelfth Supplemental Indenture) an amount of money sufficient to repurchase on the Fundamental Change Repurchase Date all of the Notes to be repurchased on such date at the Fundamental Change Repurchase Price. Subject to receipt of funds and/or Notes by the Trustee (or other Paying Agent appointed by the Company), payment for Notes surrendered for repurchase (and not withdrawn) prior to the close of business on the Fundamental Change Repurchase Date will be made promptly after the later of (x) the Fundamental Change Repurchase Date with respect to such Note (provided the Holder has satisfied the conditions to the payment of the Fundamental Change Repurchase Price in Section 9.02), and (y) the time of book-entry transfer or the delivery of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder thereof in the manner required by Section 9.02 by mailing checks for the amount payable to the Holders of such Notes entitled thereto as they shall appear in the Security Register, provided, however, that payments to the Depositary shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee. The Trustee shall, promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the Fundamental Change Repurchase Price.

(e) If the Trustee (or other Paying Agent appointed by the Company) holds money or securities sufficient to repurchase on the Fundamental Change Repurchase Date all the Notes or portions thereof that are to be purchased as of the second Business Day following the Fundamental Change Repurchase Date, then on and after the Fundamental Change Repurchase Date (i) such Notes will cease to be Outstanding, (ii) interest will cease to accrue on such Notes, and (iii) all other rights of the Holders of such Notes will terminate, whether or not book-entry transfer of the Notes has been made or the Notes have been delivered to the Trustee or Paying Agent, other than the right to receive the Fundamental Change Repurchase Price upon delivery of the Notes.

2.25% Convertible Senior Notes due 2037

This Security is one of a duly authorized issue of Securities of the Company, designated as its 2.25% Convertible Senior Notes due 2037 (herein called the “Securities”), issued under and pursuant to an Indenture dated as of March 1, 1995, as supplemented with respect to the Securities by the Second Supplemental Indenture, dated as of November 2, 2005 and the Fourth Supplemental Indenture, dated as of March 26, 2007 (as so supplemented, herein called the “Indenture”), between the Company and U.S. Bank National Association (herein called the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Securities. Additional Securities may be issued in an unlimited aggregate principal amount, subject to certain conditions specified in the Indenture. Capitalized terms used but not defined herein shall have the meanings ascribed to them in the Indenture.

In case an Event of Default, as defined in the Indenture, shall have occurred and be continuing, the principal of and interest on all Securities may be declared, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

Prior to April 5, 2012, the Company may not redeem the Securities except to preserve the Company’s status as a real estate investment trust as described in Section 3.01 of the Fourth Supplemental Indenture. Subject to the terms and conditions of the Indenture, on or after April 5, 2012, the Company shall have the right to redeem the Securities, in whole or from time to time in part, at a price equal to 100% of the principal amount of the Securities being redeemed, plus accrued and unpaid interest. Any such redemption shall be upon at least 30 days’ and no more than 60 days’ notice to Holders of the Securities.

Subject to the terms and conditions of the Indenture, the Company will make all payments and deliveries in respect of the Fundamental Change Repurchase Price, the Put Right Repurchase Price, the Redemption Price and the principal amount on the Maturity Date, as the case may be, to the Holder who surrenders a Security to a Paying Agent to collect such payments in respect of the Security. The Company will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts.

The Indenture contains provisions permitting the Company and the Trustee in certain circumstances, without the consent of the Holders of the Securities, and in other circumstances, with the consent of the Holders of not less than a majority in principal amount of the Securities at the time Outstanding, evidenced as in the Indenture provided, to execute supplemental indentures adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or modifying in any manner the rights of the Holders of the Securities; provided, however, that no such supplemental indenture shall make any of the changes set forth in Section 6.02 of the Fourth Supplemental Indenture, without the consent of each Holder of an Outstanding Security affected thereby. It is also provided in the Indenture

A-Exh A-6

that, prior to any declaration accelerating the maturity of the Securities, the Holders of a majority in principal amount of the Securities at the time Outstanding may on behalf of the Holders of all of the Securities waive any past default or Event of Default under the Indenture and its consequences except as provided in the Indenture. Any such consent or waiver by the Holder of this Security (unless revoked as provided in the Indenture) shall be conclusive and binding upon such Holder and upon all future Holders and owners of this Security and any Securities which may be issued in exchange or substitution hereof, irrespective of whether or not any notation thereof is made upon this Security or such other Securities.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and accrued and unpaid interest on this Security at the place, at the respective times, at the rate and in the lawful money herein prescribed.

The Securities are issuable in registered form without coupons in denominations of $1,000 principal amount and integral multiples thereof. At the office or agency of the Company referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, without payment of any service charge but with payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration or exchange of Securities, Securities may be exchanged for a like aggregate principal amount of Securities of other authorized denominations.

The Securities are not subject to redemption through the operation of any sinking fund.

Upon the occurrence of a Fundamental Change, the Holder has the right, at such Holder’s option, to require the Company to repurchase all of such Holder’s Securities or any portion thereof (in principal amounts of $1,000 or integral multiples thereof) on the Fundamental Change Repurchase Date at a price equal to 100% of the principal amount of the Securities such holder elects to require the Company to repurchase, together with accrued and unpaid interest to but excluding the Fundamental Change Repurchase Date. The Company or, at the written request of the Company, the Trustee shall mail to all Holders of record of the Securities a notice of the occurrence of a Fundamental Change and of the repurchase right arising as a result thereof on or before the twentieth day after the occurrence of any Fundamental Change.

On April 1, 2012, April 1, 2017, April 1, 2022, April 1, 2027 and April 1, 2032, the Holder has the right, at such Holder’s option, to require the Company to repurchase all of such Holder’s Securities or any portion thereof (in principal amounts of $1,000 or integral multiples thereof) at a price equal to 100% of the principal amount of the Securities such Holder elects to require the Company to repurchase, together with accrued and unpaid interest to but excluding the Put Right Repurchase Date. Holders shall submit their Securities for repurchase to the Paying Agent at any time from the opening of business on the date that is 25 Business Days prior to the applicable Put Right Repurchase Date until the close of business on the fifth Business Day prior to the Put Right Repurchase Date.

Subject to the provisions of the Indenture, the Holder hereof has the right, at its option, on and after February 1, 2012, or earlier upon the occurrence of certain conditions specified in the Indenture and prior to the close of business on the Trading Day immediately preceding the

A-Exh A-7

Maturity Date, to convert any Securities or portion thereof which is $1,000 or an integral multiple thereof, into cash, Common Shares or a combination of cash and Common Shares, at the option of the Company as provided in the Fourth Supplemental Indenture, in each case at the Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture, upon surrender of this Security, together with a Notice of Conversion, a form of which is attached to this Security, as provided in the Indenture and this Security, to the Company at the office or agency of the Company maintained for that purpose in the Borough of Manhattan, City of New York or the City of Boston or elsewhere as provided in the Indenture, and, unless the shares issuable on conversion are to be issued in the same name as this Security, duly endorsed by, or accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the Holder or by his duly authorized attorney. The initial Conversion Rate is 13.0576 shares for each $1,000 principal amount of Securities. No fractional Common Shares will be issued upon any conversion, but an adjustment in cash will be paid to the Holder, as provided in the Indenture, in respect of any fraction of a share which would otherwise be issuable upon the surrender of any Security or Securities for conversion. No adjustment shall be made for dividends or any shares issued upon conversion of such Security except as provided in the Indenture.

Upon due presentment for registration of transfer of this Security at the office or agency of the Company in the Borough of Manhattan, City of New York or the City of Boston, a new Security or Securities of authorized denominations for an equal aggregate principal amount will be issued to the transferee in exchange thereof, subject to the limitations provided in the Indenture, without charge except for any tax, assessments or other governmental charge imposed in connection therewith.

The Company, the Trustee, any authenticating agent, any Paying Agent, any Conversion Agent and any Security Registrar may deem and treat the registered Holder hereof as the absolute owner of this Security (whether or not this Security shall be overdue and notwithstanding any notation of ownership or other writing hereon), for the purpose of receiving payment hereof, or on account hereof, for the conversion hereof and for all other purposes, and neither the Company nor the Trustee nor any other authenticating agent nor any Paying Agent nor any other Conversion Agent nor any Security Registrar shall be affected by any notice to the contrary. All payments made to or upon the order of such registered Holder shall, to the extent of the sum or sums paid, satisfy and discharge liability for monies payable on this Security.

No recourse for the payment of the principal of, or accrued and unpaid interest on, this Security, or for any claim based hereon or otherwise in respect hereof, and no recourse under or upon any obligation, covenant or agreement of the Company in the Indenture or any indenture supplemental thereto or in any Security, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, employee, agent, officer, trustee, director or subsidiary, as such, past, present or future, of the Company or of any successor corporation, either directly or through the Company or any successor corporation, whether by virtue of any constitution, statute or rule of law or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issue hereof, expressly waived and released.

On and after October 15, 2012, regardless of the conditions described in clause (b) through (f) below, upon compliance with the provisions of this Article VIII and subject to Section 8.11 hereof, a Noteholder shall have the right, at such holder’s option, to exchange all or any portion (if the portion to be exchanged is $1,000 principal amount or an integral multiple thereof) of such Note at any time prior to the close of business on the scheduled Trading Day immediately preceding the Maturity Date at an Exchange Rate of 5.4874 shares of Common Stock (subject to adjustment by the Company as provided in Section 8.04) per $1,000 principal amount of Notes.

(b) (1) A Holder of Notes shall have the right, at such Holder’s option, to exchange its Notes prior to October 15, 2012, during the five Business Day period immediately after any ten consecutive Trading Day period (the “Measurement Period”) in which the Trading Price per $1,000 principal amount of Notes for each day of such Measurement Period was less than 98% of the product of the Last Reported Sale Price of the Common Stock on such date and the Exchange Rate on such date, all as determined by the Trustee in the manner described in the immediately succeeding paragraph. The Trustee shall have no obligation to determine the Trading Price of the Notes unless requested by the Company to do so in writing, and the Company shall have no obligation to make such request unless a Noteholder or Noteholders of at least $1,000,000 aggregate principal amount of Notes provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of the Notes would be less than 98% of the product of the Last Reported Sale Price at such time and the then-applicable Exchange Rate, at which time the Company shall select three independent nationally recognized securities dealers (each, an “Independent Securities Dealer”), request that the Independent Securities Dealers provide a secondary market quotation for the Notes and provide such determination to the Company and the Trustee in writing, and the Company shall instruct the Independent Securities Dealers to provide a secondary market quotation for the Notes beginning on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of the Notes is greater than or equal to 98% of the product of the Last Reported Sale Price on such date and the then-applicable Exchange Rate. If the Trading Price condition set forth above has been met, the Company shall so notify the Noteholders. If at any time after the Trading Price condition set forth above has been met, the Trading Price per $1,000 principal amount of Notes is greater than 98% of the product of the Last Reported Sale Price on such date and the then-applicable Exchange Rate, the Company shall so notify the Noteholders.

Unless and until a Responsible Officer of the Trustee shall have received a request from the Company for determination of the Trading Price for the Notes and the Officers’ Certificate contemplated herein, the Trustee shall have no obligation to make any determination of the Trading Price of the Notes or whether the Trading Price condition has been met.

(c) A Holder of Notes shall have the right, at such Holder’s option, to exchange Notes during any calendar quarter after the quarter ended December 31, 2007, and only during such calendar quarter, if the Last Reported Sale Price for the Common Stock for at least 20 Trading Days during the period of 30 consecutive Trading Days ending on the last Trading Day of the previous calendar quarter exceeds 130% of the Exchange Price (the “Exchange Trigger Price”) on such last Trading Day, which Exchange Price shall be subject to adjustment in accordance with this Article VIII. The Exchange Agent shall, on the Company’s behalf, determine at the beginning of each calendar quarter whether the Notes are exchangeable as a result of the price of the Common Stock as contemplated in the previous sentence and notify the Company and the Trustee.

(d) In the event that the Company has delivered a notice of redemption in accordance with Section 1104 of the Base Indenture and Section 3.03 of this Annex B of the Twelfth Supplemental Indenture to the Holders of Notes, a Holder of Notes may exchange Notes at any time prior to the close of business on the second Business Day immediately preceding the corresponding Redemption Date; provided, however, that a Holder who has already delivered a Fundamental Change Repurchase Notice with respect to a Note may not exchange such Note until the Holder has withdrawn the Fundamental Change Repurchase Notice in accordance with the terms of the Note and this Annex B of the Twelfth Supplemental Indenture.

(e) (1) In the event that the Company or Parent elects to:

(A) distribute to all or substantially all holders of Common Stock rights entitling them to purchase, for a period expiring within 60 days, shares of Common Stock at a price less than the Last Reported Sale Price of the Common Stock for the Trading Day immediately preceding the declaration date of such distribution; or

(B) distribute to all or substantially all holders of Common Stock, assets or debt securities of the Company or Parent or rights to purchase the Company’s or Parent’s securities, which distribution has a per share value (as determined by the Board of Trustees) exceeding 15% of the Last Reported Sale Price of the Common Stock on the day immediately preceding the date of declaration of such distribution,

B-15

(2) If the Company is a party to any transaction or event that constitutes a Fundamental Change, a Holder may surrender Notes for exchange at any time from and after the 30th scheduled Trading Day prior to the anticipated Effective Date of such transaction or event until the related Fundamental Change Repurchase Date and, upon such surrender, the Holder shall be entitled to the increase in the Exchange Rate, if any, specified in Section 8.01(g). The Company shall give notice to all record Noteholders and the Trustee and issue a press release of the Fundamental Change no later than 30 scheduled Trading Days prior to the anticipated Effective Date of the Fundamental Change.

(3) If Parent is a party to a consolidation, merger, binding share exchange or sale or conveyance of all or substantially all of its properties and assets, in each case pursuant to which the Common Stock would be exchanged into cash, securities and/or other property, then the Holders shall have the right to exchange Notes at any time beginning fifteen calendar days prior to the date announced by Parent as the anticipated effective date of the transaction and until and including the date that is fifteen calendar days after the date that is the effective date of such transaction; provided such transaction does not otherwise constitute a Fundamental Change to which the provisions of Section 8.01(e)(ii) shall apply. The Company shall give notice to all record Noteholders and the Trustee and issue a press release at least 20 calendar days prior to the anticipated effective date of such transaction. If the Board of Directors determines the anticipated effective date of the transaction, such determination shall be conclusive and binding on the Holders.

(g) (1) If a Noteholder elects to exchange Notes in connection with a Fundamental Change that occurs prior to January 15, 2013, the Exchange Rate applicable to each $1,000 principal amount of Notes so exchanged shall be increased by an additional number of shares of Common Stock (the “Additional Shares”) as described below. Settlement of Notes tendered for exchange to which Additional Shares shall be added to the Exchange Rate as provided in this subsection shall be settled pursuant to Section 8.02 below, as applicable. For purposes of this Section 8.01(g), an exchange shall be deemed to be “in connection with” a Fundamental Change to the extent that the related exchange notice is delivered during the time period beginning on the 30th Trading Day prior to the anticipated Effective Date of such Fundamental Change and ending on the related Fundamental Change Repurchase Date, inclusive (regardless of whether the provisions of clauses (b), (c), (d), (e) or (f) of this Section 8.01 shall apply to such exchange). Such exchange notice shall indicate that the Holder of Notes has elected to exchange Notes in connection with a Fundamental Change; provided, however, that the failure to so indicate shall not in any way affect the Exchange Obligation or the right of such Holder to receive Additional Shares in connection with such exchange.

B-16

the table, the number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the next higher and next lower Stock Price amounts and the two nearest Effective Dates, as applicable, based on a 365-day year; provided further that if (1) the Stock Price is greater than $268.62 per share of Common Stock (subject to adjustment in the same manner as set forth in Section 8.04), no Additional Shares will be added to the Exchange Rate, and (2) the Stock Price is less than $142.97 per share of Common Stock (subject to adjustment in the same manner as set forth in Section 8.04), no Additional Shares will be added to the Exchange Rate. Notwithstanding the foregoing, in no event will the total number of shares of Common Stock issuable upon exchange exceed 6.5762 per $1,000 principal amount of Notes (subject to adjustment in the same manner as set forth in clauses (a), (b) and (c) of Section 8.04).

(ii) The Stock Prices set forth in the first row of the table in Schedule A hereto shall be adjusted as of any date on which the Exchange Rate of the Notes is adjusted. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Exchange Rate in effect immediately prior to the adjustment giving rise to the Stock Price adjustment and the denominator of which is the Exchange Rate as so adjusted. The number of Additional Shares within the table shall be adjusted in the same manner as the Exchange Rate as set forth in Section 8.04 (other than by operation of an adjustment to the Exchange Rate by adding Additional Shares).

Section 8.02 Exchange Procedures.

(a) (1) The Company shall settle its Exchange Obligations as described in Section 8.02(a)(3), unless, within the applicable time period specified in this Section 8.02(a)(1), the Company elects to settle its Exchange Obligations as described in Section 8.02(a)(2) or Section 8.02(a)(4). The cash and/or shares of Common Stock which the Company is required to deliver in accordance with this Section 8.02 in settlement of its Exchange Obligations is referred to herein as the “Settlement Amount.” If the Company desires to settle its Exchange Obligations as described in Section 8.02(a)(2) or Section 8.02(a)(4), the Company shall notify each exchanging Noteholder by notice to the Trustee (for further distribution to Noteholders) of the method the Company will choose to satisfy its Exchange Obligations no later than the second Trading Day immediately following the Company’s receipt of a Notice of Exchange from such Holder, and such notice shall specify the section of this Annex B of the Twelfth Supplemental Indenture pursuant to which the Company is electing to satisfy its exchange obligations; provided, however, that the Company shall have the right to irrevocably elect, in its sole discretion and without the consent of Noteholders, by notice to the Trustee (for further distribution to Noteholders), on or prior to October 15, 2012, to settle all of its future Exchange Obligations entirely in shares of Common Stock as described in Section 8.02(a)(2), and provided further, that the Company is required to settle all exchanges with an Exchange Date occurring on or after October 15, 2012 in the same manner, and the Company shall notify Noteholders by notice to the Trustee (for further distribution to Noteholders) of the manner of settlement (including specifying the applicable section of this Annex B of the Twelfth Supplemental Indenture that describes such manner of settlement) on or before such date. The Company shall treat all Noteholders exchanging on the same Trading Day in the same manner; however, the

B-17

Company shall not have any obligation to settle its Exchange Obligations arising on different Trading Days in the same manner, except for exchanges with an Exchange Date occurring on or after October 15, 2012, which shall all be satisfied in the same manner.

(3) If the Company does not elect, within the applicable time periods specified in Section 8.02(a)(1), to settle its Exchange Obligations as described in Section 8.02(a)(2) or 8.02(a)(4), the Company shall settle its Exchange Obligations as described in this Section 8.02(a)(3), subject to Section 8.02(b) hereof. The Company shall deliver in respect of each $1,000 principal amount of Notes being exchanged a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the 20 consecutive Trading Days during the Observation Period, on the third Trading Day immediately following the last day of the related Observation Period; provided that the Company will deliver cash in lieu of fractional shares of Common Stock as set forth pursuant to clause (k) below. The Daily Settlement Amounts shall be determined by the Company promptly following the last day of the Observation Period.

(4) If the Company has elected, within the applicable time periods specified in Section 8.02(a)(1), to settle its Exchange Obligations as described in this Section 8.02(a)(4), the Company shall have the right to settle all or a portion of the amount by which the Daily Exchange Value exceeds $50 in cash in accordance with this Section 8.02(a)(4). In such case, the Company shall specify a percentage of the amount by which the Daily Exchange Value exceeds $50 that will be settled in cash, or the “cash percentage.” The Company will inform exchanging Holders by notice to the Trustee (for further distribution to Noteholders) no later than two Trading Days prior to the first day of the applicable Observation Period if it elects to pay cash upon exchange of the Notes and shall specify in such notice (the “cash percentage notice”) the applicable cash percentage. If the Company elects to specify a cash percentage, the amount of cash that the Company shall deliver in respect of each Trading Day in the applicable Observation Period shall equal the product of (w) the cash percentage and (x) the amount by which the Daily Exchange Value exceeds $50 for such Trading Day. The number of shares of Common Stock deliverable in respect of each Trading Day in the applicable Observation Period shall equal (i) the product of (y) 100% minus the cash percentage and (z) the amount by which the Daily Exchange Value exceeds $50 for such Trading Day, divided by (ii) the Daily VWAP of the Common Stock for such Trading Day. If the Company does not specify a cash percentage, it must settle the entire amount by which the Daily Exchange Value exceeds $50 with shares of Common Stock pursuant to Section 8.02(a)(3) above; provided, however, that the Company will deliver cash in lieu of fractional shares of Common Stock as set forth pursuant to clause (k)

B-18

below. If the Company specifies a cash percentage, the Company shall satisfy its Exchange Obligation by delivering, on the third Trading Day immediately following the last day of the related Observation Period, the amount of cash and the number of shares of Common Stock deliverable pursuant to this Section 8.02(a)(4).

(A) If the last day of the applicable Observation Period related to Notes surrendered for exchange is prior to the third Trading Day preceding the Effective Date of the Fundamental Change, the Company will satisfy the related Exchange Obligation with respect to each $1,000 principal amount of Notes tendered for exchange as described in Section 8.01(a) by delivering the amount of cash and shares of Common Stock, if any (based on the Exchange Rate, but without regard to the number of Additional Shares to be added to the Exchange Rate pursuant to Section 8.01(g)) on the third Trading Day immediately following the last day of the applicable Observation Period. In addition, as soon as practicable following the Effective Date of the Fundamental Change, the Company will deliver the increase in such amount of cash and Reference Property deliverable in lieu of shares of Common Stock, if any, as if the Exchange Rate had been increased by such number of Additional Shares during the related Observation Period (and based upon the related Daily VWAP prices during such Observation Period). If such increased amount of cash and Common Stock, if any, results in an increase to the amount of cash to be paid to Holders, the Company will pay such increase in cash, and if such increased amount results in an increase to the number of shares of Common Stock, the Company will deliver such increase by delivering Reference Property based on such increased number of shares.

(B) If the last day of the applicable Observation Period related to Notes surrendered for exchange is on or following the third scheduled Trading Day preceding the Effective Date of such Fundamental Change, the Company will satisfy the Exchange Obligation with respect to each $1,000 principal amount of Notes tendered for exchange as described in Section 8.01(a) (based on the Exchange Rate as increased by the Additional Shares pursuant to Section 8.01(g) above) on the later to occur of (x) the Effective Date of the Fundamental Change and (y) the third Trading Day immediately following the last day of the applicable Observation Period.

(g) Except as provided in Section 8.04, no adjustment shall be made for dividends on any shares issued upon the exchange of any Note as provided in this Article.

(j) The Person in whose name the certificate for any shares of Common Stock issued upon exchange is registered shall be treated as a stockholder of record on and after the Exchange Date; provided, however, that no surrender of Notes on any date when the stock transfer books of the Company shall be closed shall be effective to constitute the Person or Persons entitled to receive the shares of Common Stock upon such exchange as the record holder or holders of such shares of Common Stock on such date, but such surrender shall be effective to constitute the Person or Persons entitled to receive such shares of Common Stock as the record holder or holders thereof for all purposes at the close of business on the next succeeding day on which such stock transfer books are open; such exchange shall be at the Exchange Rate in effect on the date that such Notes shall have been surrendered for exchange, as if the stock transfer books of the Company had not been closed. Upon exchange of Notes, such Person shall no longer be a Noteholder.

In addition, in the event of any distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Exchange Rate under this Section 8.04 was made, (1) in the case of any such rights or warrants that shall all have been redeemed or repurchased without exercise by any holders thereof, the Exchange Rate shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder or holders of Common Stock with respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights or warrants that shall have expired or

been terminated without exercise by any holders thereof, the Exchange Rate shall be readjusted as if such rights and warrants had not been issued.

No adjustment shall be made to the Exchange Rate unless such adjustment would require a change of at least 1% in the Exchange Rate then in effect at such time. The Company shall carry forward any adjustments that are less than 1% of the Exchange Rate and make such carried forward adjustments,

Notwithstanding the foregoing provisions of this Section 8.04, in no event will the total number of Common Stock issuable upon exchange exceed 6.5762 per $1,000 principal amount of Notes (subject to adjustment in the same manner or as set forth in clauses (a), (b) and (c) of this Section 8.04).

Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture.

(d) The above provisions of this Section shall similarly apply to successive Merger Events.

Section 8.09 Notice to Holders Prior to Certain Actions.

In case:

(a) Parent shall declare a dividend (or any other distribution) on its Common Stock that would require an adjustment in the Exchange Rate pursuant to Section 8.04; or

(b) Parent shall authorize the granting to all of the holders of its Common Stock of rights or warrants to subscribe for or purchase any share of any class or any other rights or warrants;

B-31

(c) of any reclassification of the Common Stock (other than a subdivision or combination of its outstanding Common Stock, or a change in par value, or from par value to no par value, or from no par value to par value), or of any consolidation or merger to which Parent is a party and for which approval of any stockholders of Parent is required, or of the sale or transfer of all or substantially all of the assets of Parent; or

(d) of the voluntary or involuntary dissolution, liquidation or winding-up of Parent,

Section 8.11 Ownership Limit. Notwithstanding any other provision of this Annex B of the Twelfth Supplemental Indenture or the Notes, no Holder of Notes (or beneficial owner of Notes) shall be entitled to exchange such Notes for shares of Common Stock to the extent that receipt of such shares would cause such Holder (or beneficial owner of Notes) (together with such Holder’s (or beneficial owner’s) affiliates) to exceed the applicable ownership limit contained in the articles of incorporation of Parent.

The Trustee shall have no obligation to determine the Trading Price of the Notes unless requested by the Company to do so in writing, and the Company shall have no obligation to make such request unless a Noteholder or Noteholders of at least $1,000,000 aggregate principal amount of Notes provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of the Notes would be less than 98% of the product of the Last Reported Sale Price at such time and the then-applicable Exchange Rate, at which time the Company shall select three independent nationally recognized securities dealers (each, an “Independent Securities Dealer”), request that the Independent Securities Dealers provide a secondary market quotation for the Notes and provide such determination to the Company and the Trustee in writing, and the Company shall instruct the Independent Securities Dealers to provide a secondary market quotation for the Notes beginning on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of the Notes is greater than or equal to 98% of the product of the Last Reported Sale Price on such date and the then-applicable Exchange Rate. If the Trading Price condition set forth above has been met, the Company shall so notify the Noteholders. If at any time after the Trading Price condition set forth above has been met, the Trading Price per $1,000 principal amount of Notes is greater than 98% of the product of the Last Reported Sale Price on such date and the then-applicable Exchange Rate, the Company shall so notify the Noteholders.

C-14

(2) Any request by the Company to the Trustee for a determination of the Trading Price and whether the Trading Price condition set forth in the first sentence of the immediately preceding paragraph has been met shall be accompanied by an Officers’ Certificate setting forth, for each day of determination (as identified in such Certificate), the name of the Independent Securities Dealers providing the secondary market bid quotations, a statement certifying that that such dealers are “Independent Securities Dealers” as required in this Section 8.01, the secondary market bid quotations obtained from such Independent Securities Dealers (a copy of which will be attached to such Officers’ Certificate), the Company’s calculation of the Trading Price for such date. The Trustee shall be entitled to conclusively rely, without independent verification, on the quotations provided by the Company in making its determinations hereunder. On the basis of such quotations, the Trustee shall determine the Trading Price of the Notes, and provide such determination to the Company. Absent manifest error, the Trustee’s determination of the Trading Price will be binding on the Company. Unless and until a Responsible Officer of the Trustee shall have received a request from the Company for determination of the Trading Price for the Notes and the Officers’ Certificate contemplated herein, the Trustee shall have no obligation to make any determination of the Trading Price of the Notes or whether the Trading Price condition has been met.

(c) A Holder of Notes shall have the right, at such Holder’s option, to exchange Notes during any calendar quarter after the quarter ended June 30, 2008, and only during such calendar quarter, if the Last Reported Sale Price for the Common Stock for at least 20 Trading Days during the period of 30 consecutive Trading Days ending on the last Trading Day of the previous calendar quarter exceeds 130% of the Exchange Price (the “Exchange Trigger Price”) on such last Trading Day, which Exchange Price shall be subject to adjustment in accordance with this Article VIII. The Exchange Agent shall, on the Company’s behalf, determine at the beginning of each calendar quarter whether the Notes are exchangeable as a result of the price of the Common Stock as contemplated in the previous sentence and notify the Company and the Trustee.

(d) In the event that the Company has delivered a notice of redemption in accordance with Section 1104 of the Base Indenture and Section 3.03 of this Annex C of the Twelfth Supplemental Indenture to the Holders of Notes, a Holder of Notes may exchange Notes at any time prior to the close of business on the second Business Day immediately preceding the corresponding Redemption Date; provided, however, that a Holder who has already delivered a Fundamental Change Repurchase Notice with respect to a Note may not exchange such Note until the Holder has withdrawn the Fundamental Change Repurchase Notice in accordance with the terms of the Note and this Annex C of the Twelfth Supplemental Indenture.

(e) (i) In the event that Parent or Company elects to:

C-15

(g) (1) If a Noteholder elects to exchange Notes in connection with a Fundamental Change that occurs prior to May 20, 2013, the Exchange Rate applicable to each $1,000 principal amount of Notes so exchanged shall be increased by an additional number of shares of Common Stock (the “Additional Shares”) as described below. Settlement of Notes tendered for exchange to which Additional Shares shall be added to the Exchange Rate as

C-16

provided in this subsection shall be settled pursuant to Section 8.02 below, as applicable. For purposes of this Section 8.01(g), an exchange shall be deemed to be “in connection with” a Fundamental Change to the extent that the related exchange notice is delivered during the time period beginning on the 30th Trading Day prior to the anticipated Effective Date of such Fundamental Change and ending on the related Fundamental Change Repurchase Date, inclusive (regardless of whether the provisions of clauses (b), (c), (d), (e) or (f) of this Section 8.01 shall apply to such exchange). Such exchange notice shall indicate that the Holder of Notes has elected to exchange Notes in connection with a Fundamental Change; provided, however, that the failure to so indicate shall not in any way affect the Exchange Obligation or the right of such Holder to receive Additional Shares in connection with such exchange.

(i) The number of Additional Shares by which the Exchange Rate will be increased shall be determined by reference to the table attached as Schedule A hereto, based on the date on which the Fundamental Change occurs or becomes effective (the “Effective Date”), and the Stock Price; provided, that if the Stock Price is between two Stock Price amounts in the table or the Effective Date is between two Effective Dates in the table, the number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the next higher and next lower Stock Price amounts and the two nearest Effective Dates, as applicable, based on a 365-day year; provided further that if (1) the Stock Price is greater than $268.82 per share of Common Stock (subject to adjustment in the same manner as set forth in Section 8.04), no Additional Shares will be added to the Exchange Rate, and (2) the Stock Price is less than $140.82 per share of Common Stock (subject to adjustment in the same manner as set forth in Section 8.04), no Additional Shares will be added to the Exchange Rate. Notwithstanding the foregoing, in no event will the total number of shares of Common Stock issuable upon exchange exceed 7.1015 per $1,000 principal amount of Notes (subject to adjustment in the same manner as set forth in clauses (a), (b) and (c) of Section 8.04).

Section 8.02 Exchange Procedures.

C-17

described in Section 8.02(a)(2) or Section 8.02(a)(4), the Company shall notify each exchanging Noteholder by notice to the Trustee (for further distribution to Noteholders) of the method the Company will choose to satisfy its Exchange Obligations no later than the second Trading Day immediately following the Company’s receipt of a Notice of Exchange from such Holder, and such notice shall specify the section of this Annex C of the Twelfth Supplemental Indenture pursuant to which the Company is electing to satisfy its exchange obligations; provided, however, that the Company shall have the right to irrevocably elect, in its sole discretion and without the consent of Noteholders, by notice to the Trustee (for further distribution to Noteholders), on or prior to February 15, 2013, to settle all of its future Exchange Obligations entirely in shares of Common Stock as described in Section 8.02(a)(2), and provided further, that the Company is required to settle all exchanges with an Exchange Date occurring on or after February 15, 2013 in the same manner, and the Company shall notify Noteholders by notice to the Trustee (for further distribution to Noteholders) of the manner of settlement (including specifying the applicable section of this Annex C of the Twelfth Supplemental Indenture that describes such manner of settlement) on or before such date. The Company shall treat all Noteholders exchanging on the same Trading Day in the same manner; however, the Company shall not have any obligation to settle its Exchange Obligations arising on different Trading Days in the same manner, except for exchanges with an Exchange Date occurring on or after February 15, 2013, which shall all be satisfied in the same manner.

(3) If the Company does not elect, within the applicable time periods specified in Section 8.02(a)(1), to settle its Exchange Obligations as described in Section 8.02(a)(2) or 8.02(a)(4), the Company shall settle its Exchange Obligations as described in this Section 8.02(a)(3), subject to Section 8.02(b) hereof. The Company shall deliver in respect of each $1,000 principal amount of Notes being exchanged a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the 20 consecutive Trading Days during the Observation Period, on the third Trading Day immediately following the last day of the related Observation Period; provided that the Company will deliver cash in lieu of fractional shares of Common Stock as set forth pursuant to clause (k) below. The Daily Settlement Amounts shall be determined by the Company promptly following the last day of the Observation Period.

(4) If the Company has elected, within the applicable time periods specified in Section 8.02(a)(1), to settle its Exchange Obligations as described in this Section

C-18

8.02(a)(4), the Company shall have the right to settle all or a portion of the amount by which the Daily Exchange Value exceeds $50 in cash in accordance with this Section 8.02(a)(4). In such case, the Company shall specify a percentage of the amount by which the Daily Exchange Value exceeds $50 that will be settled in cash, or the “cash percentage.” The Company will inform exchanging Holders by notice to the Trustee (for further distribution to Noteholders) no later than two Trading Days prior to the first day of the applicable Observation Period if it elects to pay cash upon exchange of the Notes and shall specify in such notice (the “cash percentage notice”) the applicable cash percentage. If the Company elects to specify a cash percentage, the amount of cash that the Company shall deliver in respect of each Trading Day in the applicable Observation Period shall equal the product of (w) the cash percentage and (x) the amount by which the Daily Exchange Value exceeds $50 for such Trading Day. The number of shares of Common Stock deliverable in respect of each Trading Day in the applicable Observation Period shall equal (i) the product of (y) 100% minus the cash percentage and (z) the amount by which the Daily Exchange Value exceeds $50 for such Trading Day, divided by (ii) the Daily VWAP of the Common Stock for such Trading Day. If the Company does not specify a cash percentage, it must settle the entire amount by which the Daily Exchange Value exceeds $50 with shares of Common Stock pursuant to Section 8.02(a)(3) above; provided, however, that the Company will deliver cash in lieu of fractional shares of Common Stock as set forth pursuant to clause (k) below. If the Company specifies a cash percentage, the Company shall satisfy its Exchange Obligation by delivering, on the third Trading Day immediately following the last day of the related Observation Period, the amount of cash and the number of shares of Common Stock deliverable pursuant to this Section 8.02(a)(4).

C-21

for exchange after 5:00 p.m., New York City time on the Record Date immediately preceding the Maturity Date. Except as described above, no payment or adjustment will be made for accrued interest on exchanged Notes.

(j) The Person in whose name the certificate for any shares of Common Stock issued upon exchange is registered shall be treated as a stockholder of record on and after the Exchange Date; provided, however, that no surrender of Notes on any date when the stock transfer books of the Company shall be closed shall be effective to constitute the Person or Persons entitled to receive the shares of Common Stock upon such exchange as the record holder or holders of such shares of Common Stock on such date, but such surrender shall be effective to constitute the Person or Persons entitled to receive such shares of Common Stock as the record holder or holders thereof for all purposes at the close of business on the next succeeding day on which such stock transfer books are open; such exchange shall be at the Exchange Rate in effect on the date that such Notes shall have been surrendered for exchange, as if the stock transfer books of the Company had not been closed. Upon exchange of Notes, such Person shall no longer be a Noteholder.

C-22


ER' =		the Exchange Rate in effect as of the Ex-Date for such dividend or distribution or the effective date of such share split or combination, as the case may be;

OS₀ =		the number of shares of Common Stock outstanding immediately prior to such event; and

OS' =		the number of shares of Common Stock outstanding immediately after such event.


		where

ER₀ =		the Exchange Rate in effect immediately prior to the Ex-Date for such distribution;

ER' =		the Exchange Rate in effect as of the Ex-Date for such distribution;

OS₀ =		the number of shares of Common Stock outstanding immediately prior to such event;

X =		the total number of shares of Common Stock issuable pursuant to such rights, warrants or convertible securities; and

Y =		the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, warrants or convertible securities divided by the average of the Last Reported Sale Prices per share of Common Stock over the ten consecutive Trading Day period ending on the Business Day immediately preceding the record date (or, if later, the Ex-Date relating to such distribution) for the issuance of such rights, warrants or convertible securities.

C-23

warrants or convertible securities are not so exercised prior to their expiration, the Exchange Rate shall again be adjusted to be the Exchange Rate that would then be in effect if such record date for such distribution had not been fixed.


		where

ER₀ =		the Exchange Rate in effect immediately prior to the Ex-Date for such distribution;

ER' =		the Exchange Rate in effect as of the Ex-Date for such distribution;

SP₀ =		the average of the Last Reported Sale Prices of the Common Stock over the ten consecutive Trading Day period ending on the Business Day immediately preceding the record date for such distribution (or, if earlier, the Ex-Date relating to such distribution); and

If such dividend or distribution is not so paid or made, the Exchange Rate shall again be adjusted to be the Exchange Rate that would then be in effect if such dividend or distribution had not been declared. If the Board of Trustees determines the fair market value of any distribution for purposes of this Section 8.04(c) by reference to the actual or when issued trading market for any securities, it must in doing so consider the prices in such market over the same period used in determining SP0 above.


		where

ER₀ =		the Exchange Rate in effect immediately prior to such distribution;

ER' =		the Exchange Rate in effect immediately after such distribution;

FMV₀ =		the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of shares of Common Stock applicable to one share of Common Stock over the first ten consecutive Trading Day period after the effective date of the Spin-Off; and

C-25

(and no adjustment to the Exchange Rate under this Section 8.04 will be required) until the occurrence of the earliest Trigger Event, whereupon such rights and warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Exchange Rate shall be made under this Section 8.04(c). If any such right or warrant, including any such existing rights or warrants distributed prior to the date of this Annex C of the Twelfth Supplemental Indenture, are subject to events, upon the occurrence of which such rights or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and record date with respect to new rights or warrants with such rights (and a termination or expiration of the existing rights or warrants without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Exchange Rate under this Section 8.04 was made, (1) in the case of any such rights or warrants that shall all have been redeemed or repurchased without exercise by any holders thereof, the Exchange Rate shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder or holders of Common Stock with respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights or warrants that shall have expired or been terminated without exercise by any holders thereof, the Exchange Rate shall be readjusted as if such rights and warrants had not been issued.

T =		the dividend threshold amount (“Dividend Threshold Amount”), which amount shall initially be $1.1593 per quarter and which shall be appropriately adjusted from time to time for any stock dividends on, or subdivisions or combinations of, Common Stock; provided, that if an Exchange Rate adjustment is required to be made as a result of a distribution that is not a quarterly dividend either in whole or in part, the Dividend Threshold Amount shall be deemed to be zero; and

C =		the amount in cash per share that Parent distributes to holders of Common Stock.

C-27

succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer (as it may be amended), the Exchange Rate shall be increased based on the following formula:

In addition, the Company may also (but is not required to) increase the Exchange Rate to avoid or diminish any income tax to holders of Common Stock or rights to purchase shares of Common Stock in connection with any dividend or distribution of shares (or rights to acquire shares) or similar event. Whenever the Exchange Rate is increased pursuant to the preceding sentence, the Company shall mail to the Holder of each Note at his last address appearing on the Security Register a notice of the increase at least five days prior to the date the increased Exchange Rate takes effect, and such notice shall state the increased Exchange Rate and the period during which it will be in effect.

Notwithstanding the foregoing provisions of this Section 8.04, in no event will the total number of Common Stock issuable upon exchange exceed 7.1015 per $1,000 principal amount of Notes (subject to adjustment in the same manner or as set forth in clauses (a), (b) and (c) of this Section 8.04).

(a) the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture (which, as evidenced in an Opinion of Counsel delivered to the Trustee, shall comply with the Trust Indenture Act as in force at the date of execution of such supplemental indenture if such supplemental indenture is then required to so comply) providing for the exchange and settlement of the Notes as set forth in this Annex C of the Twelfth Supplemental Indenture. Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article and the Trustee may conclusively rely on the determination by the Company of the equivalency of such adjustments. If, in the case of any Merger Event, the Reference Property includes shares of stock or other securities and assets of a corporation other than the successor or purchasing corporation, as the case may be, in such reclassification, change, consolidation, merger, combination, sale or conveyance, then such supplemental indenture shall also be executed by such other corporation and shall contain such additional provisions to protect the interests of the Holders of the Notes as the Board of Trustees shall reasonably consider necessary by reason of the foregoing, including to the extent required by the Board of Trustees and practicable the provisions providing for the repurchase rights set forth in Article IX herein.

thereafter to exchange its Notes, subject to the successor’s right to deliver cash, shares of Common Stock or common stock of such successor or a combination of cash and shares of Common Stock as set forth in Section 8.02(b), into cash (up to the aggregate principal amount thereof) and, in lieu of the shares of Common Stock otherwise deliverable, the same type (and in the same proportion) of Reference Property, based on the Daily Settlement Amounts of Reference Property in an amount equal to the applicable Exchange Rate, as described under Section 8.02(b). For purposes of determining the constitution of Reference Property, the type and amount of consideration that a holder of Common Stock would have been entitled to in the case of reclassifications, consolidations, mergers, sales or conveyance of assets or other transactions that cause the Common Stock to be converted into the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election) will be deemed to be the weighted average of the types and amounts of consideration received by the holders of shares of Common Stock that affirmatively make such an election. Parent shall not become a party to any such transaction unless its terms are consistent with the preceding. None of the foregoing provisions shall affect the right of a Holder of Notes to exchange its Notes in accordance with the provisions of Article VIII hereof prior to the effective date.

(d) The above provisions of this Section shall similarly apply to successive Merger Events.

Section 8.09 Notice to Holders Prior to Certain Actions.

In case:

(a) Parent shall declare a dividend (or any other distribution) on its Common Stock that would require an adjustment in the Exchange Rate pursuant to Section 8.04; or

(b) Parent shall authorize the granting to all of the holders of its Common Stock of rights or warrants to subscribe for or purchase any share of any class or any other rights or warrants;

(d) of the voluntary or involuntary dissolution, liquidation or winding-up of Parent,

C-32

Notes, then no other adjustment pursuant to this Article VIII shall be made in connection with such stockholder rights plans.

Section 8.11 Ownership Limit. Notwithstanding any other provision of this Annex C of the Twelfth Supplemental Indenture or the Notes, no Holder of Notes (or beneficial owner of Notes) shall be entitled to exchange such Notes for shares of Common Stock to the extent that receipt of such shares would cause such Holder (or beneficial owner of Notes) (together with such Holder’s (or beneficial owner’s) affiliates) to exceed the applicable ownership limit contained in the articles of incorporation of Parent.

2.625% Convertible Senior Notes due 2038

This Security is one of a duly authorized issue of Securities of the Company, designated as its 2.625% Convertible Senior Notes due 2038 (herein called the “Securities”), issued under and pursuant to an Indenture dated as of March 1, 1995, as supplemented with respect to the Securities by the Second Supplemental Indenture, dated as of November 2, 2005 and the Sixth Supplemental Indenture, dated as of May 7, 2008 (as so supplemented, herein called the “Indenture”), between the Company and U.S. Bank National Association (herein called the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Securities. Additional Securities may be issued in an unlimited aggregate principal amount, subject to certain conditions specified in the Indenture. Capitalized terms used but not defined herein shall have the meanings ascribed to them in the Indenture.

Prior to May 20, 2013, the Company may not redeem the Securities except to preserve the Company’s status as a real estate investment trust as described in Section 3.01 of the Sixth Supplemental Indenture. Subject to the terms and conditions of the Indenture, on or after May 20, 2013, the Company shall have the right to redeem the Securities, in whole or from time to time in part, at a price equal to 100% of the principal amount of the Securities being redeemed, plus accrued and unpaid interest. Any such redemption shall be upon at least 30 days’ and no more than 60 days’ notice to Holders of the Securities.

The Indenture contains provisions permitting the Company and the Trustee in certain circumstances, without the consent of the Holders of the Securities, and in other circumstances, with the consent of the Holders of not less than a majority in principal amount of the Securities at the time Outstanding, evidenced as in the Indenture provided, to execute supplemental indentures adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or modifying in any manner the rights of the Holders of the Securities; provided, however, that no such supplemental indenture shall make any of the changes set forth in Section 6.02 of the Sixth Supplemental Indenture, without the consent of each Holder of an Outstanding Security affected thereby. It is also provided in the Indenture

C-Exh A-5

The Securities are not subject to redemption through the operation of any sinking fund.

On May 15, 2013, May 15, 2018, May 15, 2023, May 15, 2028 and May 15, 2033, the Holder has the right, at such Holder’s option, to require the Company to repurchase all of such Holder’s Securities or any portion thereof (in principal amounts of $1,000 or integral multiples thereof) at a price equal to 100% of the principal amount of the Securities such Holder elects to require the Company to repurchase, together with accrued and unpaid interest to but excluding the Put Right Repurchase Date. Holders shall submit their Securities for repurchase to the Paying Agent at any time from the opening of business on the date that is 25 Business Days prior to the applicable Put Right Repurchase Date until the close of business on the fifth Business Day prior to the Put Right Repurchase Date.

Subject to the provisions of the Indenture, the Holder hereof has the right, at its option, on and after February 15, 2013, or earlier upon the occurrence of certain conditions specified in the Indenture and prior to the close of business on the Trading Day immediately preceding the

C-Exh A-6

Maturity Date, to convert any Securities or portion thereof which is $1,000 or an integral multiple thereof, into cash, Common Shares or a combination of cash and Common Shares, at the option of the Company as provided in the Sixth Supplemental Indenture, in each case at the Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture, upon surrender of this Security, together with a Notice of Conversion, a form of which is attached to this Security, as provided in the Indenture and this Security, to the Company at the office or agency of the Company maintained for that purpose in the Borough of Manhattan, City of New York or the City of Boston or elsewhere as provided in the Indenture, and, unless the shares issuable on conversion are to be issued in the same name as this Security, duly endorsed by, or accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the Holder or by his duly authorized attorney. The initial Conversion Rate is 13.1203 shares for each $1,000 principal amount of Securities. No fractional Common Shares will be issued upon any conversion, but an adjustment in cash will be paid to the Holder, as provided in the Indenture, in respect of any fraction of a share which would otherwise be issuable upon the surrender of any Security or Securities for conversion. No adjustment shall be made for dividends or any shares issued upon conversion of such Security except as provided in the Indenture.

EXCHANGE OF NOTES

Section 8.01 Exchange Privilege.

(a) Subject to the conditions described in Section 8.11 hereof, and upon compliance with the provisions of this Article VIII, a Holder of Notes shall have the right, at such Holder’s option, to exchange all or any portion (if the portion to be exchanged is $1,000 principal amount or an integral multiple thereof) of such Note at any time prior to the close of business on the scheduled Trading Day immediately preceding the Maturity Date at a rate (the “Exchange Rate”) of 25.8244 shares of Common Stock (subject to adjustment by the Company as provided in Section 8.04) per $1,000 principal amount of Notes (the “Exchange Obligation”) under the circumstances and during the periods set forth below.

(b) Intentionally Omitted.

(d) In the event that the Company has delivered a notice of redemption in accordance with Section 1104 of the Base Indenture and Section 3.03 of this Annex D of the Twelfth Supplemental Indenture to the Holders of Notes, a Holder of Notes may exchange Notes at any time prior to the close of business on the second Business Day immediately preceding the corresponding Redemption Date; provided, however, that a Holder who has already delivered a Fundamental Change Repurchase Notice with respect to a Note may not exchange such Note until the Holder has withdrawn the Fundamental Change Repurchase Notice in accordance with the terms of the Note and this Annex D of the Twelfth Supplemental Indenture.

(e) Intentionally Omitted.

(f) Intentionally Omitted.

(g) (1) If a Noteholder elects to exchange Notes in connection with a Fundamental Change, the Exchange Rate applicable to each $1,000 principal amount of Notes so exchanged shall be increased by an additional number of shares of Common Stock (the “Additional Shares”) as described below. Settlement of Notes tendered for exchange to which Additional Shares shall be added to the Exchange Rate as provided in this subsection shall be

D-12

settled pursuant to Section 8.02 below, as applicable. For purposes of this Section 8.01(g), an exchange shall be deemed to be “in connection with” a Fundamental Change to the extent that the related exchange notice is delivered during the time period beginning on the 30th Trading Day prior to the anticipated Effective Date of such Fundamental Change and ending on the related Fundamental Change Repurchase Date, inclusive. Such exchange notice shall indicate that the Holder of Notes has elected to exchange Notes in connection with a Fundamental Change; provided, however, that the failure to so indicate shall not in any way affect the Exchange Obligation or the right of such Holder to receive Additional Shares in connection with such exchange. The Company shall give notice to all record Noteholders and the Trustee and issue a press release of the Fundamental Change no later than 30 scheduled Trading Days prior to the anticipated effective date of the Fundamental Change.

(i) The number of Additional Shares by which the Exchange Rate will be increased shall be determined by reference to the table attached as Schedule A hereto, based on the date on which the Fundamental Change occurs or becomes effective (the “Effective Date”), and the Stock Price; provided, that if the Stock Price is between two Stock Price amounts in the table or the Effective Date is between two Effective Dates in the table, the number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the next higher and next lower Stock Price amounts and the two nearest Effective Dates, as applicable, based on a 365-day year; provided further that if (1) the Stock Price is greater than $89.61 per share of Common Stock (subject to adjustment in the same manner as set forth in Section 8.04), no Additional Shares will be added to the Exchange Rate, and (2) the Stock Price is less than $30.02 per share of Common Stock (subject to adjustment in the same manner as set forth in Section 8.04), no Additional Shares will be added to the Exchange Rate. Notwithstanding the foregoing, in no event will the total number of shares of Common Stock issuable upon exchange exceed 33.3134 per $1,000 principal amount of Notes (subject to adjustment in the same manner as set forth in clauses (a), (b) and (c) of Section 8.04).

Section 8.02 Exchange Procedures.

(a) (1) The Company shall settle its Exchange Obligations entirely in shares of Common Stock. In satisfying its Exchange Obligations, the Company shall deliver a number of shares of Common Stock equal to (i) the aggregate principal amount of Notes to be exchanged divided by $1,000, multiplied by (ii) the applicable Exchange Rate (which shall include any increases to reflect any Additional Shares that such Holder is entitled to receive

D-13

pursuant to Section 8.01(g) above). The Company shall deliver such shares of Common Stock, together with any cash in lieu of fractional shares of Common Stock as set forth pursuant to clause (k) below, on the third Business Day immediately following the applicable Exchange Date. Notwithstanding the preceding sentence, if any calculation required in order to determine the number of shares of Common Stock to be delivered by the Company in respect of a particular exchange is based upon data that will not be available to the Company on the applicable Exchange Date, the Company shall be entitled to delay settlement of that exchange until the third Business Day after the relevant data become available.

(b) Intentionally Omitted.

(c) Before any Holder of a Note shall be entitled to exchange the same as set forth above, such Holder shall (1) in the case of a Global Note, comply with the procedures of the Depositary in effect at that time and, if required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 4.01(b) and Section 8.02(i) and, if required, pay all taxes or duties, if any, and (2) in the case of a Note issued in certificated form, (A) complete and manually sign and deliver an irrevocable written notice to the Exchange Agent in the form on the reverse of such certificated Note (or a facsimile thereof) (a “Notice of Exchange”) at the office of the Exchange Agent and shall state in writing therein the principal amount of Notes to be exchanged and the name or names (with addresses) in which such Holder wishes the certificate or certificates for any shares of Common Stock to be delivered upon settlement of the Exchange Obligation to be registered, (B) surrender such Notes, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer documents), at the office of the Exchange Agent, (C) if required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 4.01(b) and Section 8.02(i), and (D) if required, pay all taxes or duties, if any. A Note shall be deemed to have been exchanged immediately prior to the close of business on the date (the “Exchange Date”) that the Holder has complied with the requirements set forth in this Section 8.02(c).

No Notice of Exchange with respect to any Notes may be tendered by a Holder thereof if such Holder has also tendered a Fundamental Change Repurchase Notice and not validly withdrawn such Fundamental Change Repurchase Notice in accordance with the applicable provisions of Section 9.02.

(d) Delivery of the amounts owing in satisfaction of the Exchange Obligation shall be made by the Company in no event later than the date specified in Section 8.02(a). The Company shall make such delivery by issuing, or causing to be issued, and delivering to the Exchange Agent or to such Holder, or such Holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the number of full shares of Common Stock to which such Holder shall be entitled as part of such Exchange Obligation (together with any cash in lieu of fractional shares).

D-14

(g) Except as provided in Section 8.04, no adjustment shall be made for dividends on any shares issued upon the exchange of any Note as provided in this Article.

(i) Upon exchange, a Noteholder will not receive any separate cash payment for accrued and unpaid interest, except as set forth below. The Company’s settlement of its Exchange Obligation as described above shall be deemed to satisfy its obligation to pay the principal amount of the Note and accrued and unpaid interest to, but not including, the Exchange Date. As a result, accrued and unpaid interest to, but not including, the Exchange Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Notwithstanding the preceding sentence, if Notes are exchanged after the close of business on a Record Date, Holders of such Notes as of the close of business on the Record Date will receive the interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the exchange. Notes surrendered for exchange during the period from the close of business on any regular Record Date to the opening of business on the corresponding Interest Payment Date must be accompanied by payment of an amount equal to the interest payable on the Notes so exchanged; provided, however, that no such payment need be made (1) if the Company has called the Notes for redemption or (2) to the extent of any overdue interest existing at the time of exchange with respect to such Note, (3) to Notes surrendered for exchange in connection with a Fundamental Change in which the Company has specified a Fundamental Change Repurchase Date that is after a Record Date and on or prior to the next Interest Payment Date, or (4) to Notes surrendered for exchange after 5:00 p.m., New York City time on the Record Date immediately preceding the Maturity Date. Except as described above, no payment or adjustment will be made for accrued interest on exchanged Notes.

D-15

(j) The Person in whose name the certificate for any shares of Common Stock issued upon exchange is registered shall be treated as a stockholder of record on and after the Exchange Date; provided, however, that no surrender of Notes on any date when the stock transfer books of the Company shall be closed shall be effective to constitute the Person or Persons entitled to receive the shares of Common Stock upon such exchange as the record holder or holders of such shares of Common Stock on such date, but such surrender shall be effective to constitute the Person or Persons entitled to receive such shares of Common Stock as the record holder or holders thereof for all purposes at the close of business on the next succeeding day on which such stock transfer books are open; such exchange shall be at the Exchange Rate in effect on the date that such Notes shall have been surrendered for exchange, as if the stock transfer books of the Company had not been closed. Upon exchange of Notes, such Person shall no longer be a Noteholder.

Section 8.03 Reserved.

Section 8.04 Adjustment of Exchange Rate. The Exchange Rate shall be adjusted from time to time by the Company as follows:

where

ER₀	=	the Exchange Rate in effect immediately prior to the Ex-Date for such dividend or distribution or the effective date of such share split or combination, as the case may be;

ER'	=	the Exchange Rate in effect as of the Ex-Date for such dividend or distribution or the effective date of such share split or combination, as the case may be;

D-16

OS₀	=	the number of shares of Common Stock outstanding immediately prior to such event; and

OS¢	=	the number of shares of Common Stock outstanding immediately after such event.

Such adjustment shall become effective immediately after 9:00 a.m., New York City time, on the Business Day following the record date fixed for such determination. If any dividend or distribution of the type described in this Section 8.04(a) is declared but not so paid or made, or the outstanding shares of Common Stock are not subdivided or combined, as the case may be, the Exchange Rate shall be immediately readjusted, effective as of the date the Board of Trustees determines not to pay such dividend or distribution, or subdivide or combine the outstanding shares of Common Stock, as the case may be, to the Exchange Rate that would then be in effect if such dividend, distribution, subdivision or combination had not been declared.

where

ER₀	=	the Exchange Rate in effect immediately prior to the Ex-Date for such distribution;

ER¢	=	the Exchange Rate in effect as of the Ex-Date for such distribution;

OS₀	=	the number of shares of Common Stock outstanding immediately prior to such event;

X	=	the total number of shares of Common Stock issuable pursuant to such rights, warrants or convertible securities; and

Y	=	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, warrants or convertible securities divided by the average of the Last Reported Sale Prices per share of Common Stock over the ten consecutive Trading Day period ending on the Business Day immediately preceding the record date (or, if later, the Ex-Date relating to such distribution) for the issuance of such rights, warrants or convertible securities.

D-17

where

ER₀	=	the Exchange Rate in effect immediately prior to the Ex-Date for such distribution;

ER¢	=	the Exchange Rate in effect as of the Ex-Date for such distribution;

SP₀	=	the average of the Last Reported Sale Prices of the Common Stock over the ten consecutive Trading Day period ending on the Business Day immediately preceding the record date for such distribution (or, if earlier, the Ex-Date relating to such distribution); and

FMV	=	the fair market value (as determined by the Board of Trustees) of the Distributed Property distributed with respect to each outstanding share of Common Stock on the record date for such distribution (or, if earlier, the Ex-Date relating to such distribution).

D-18

equal to or greater than SP₀ as set forth above, in lieu of the foregoing adjustment, adequate provision shall be made so that each Noteholder shall have the right to receive, for each $1,000 principal amount of Notes upon exchange, the amount of Distributed Property such Holder would have received had such Holder owned a number of shares of Common Stock equal to the Exchange Rate on the record date. If such dividend or distribution is not so paid or made, the Exchange Rate shall again be adjusted to be the Exchange Rate that would then be in effect if such dividend or distribution had not been declared. If the Board of Trustees determines the fair market value of any distribution for purposes of this Section 8.04(c) by reference to the actual or when issued trading market for any securities, it must in doing so consider the prices in such market over the same period used in determining SP₀ above.

where

ER₀	=	the Exchange Rate in effect immediately prior to such distribution;

ER¢	=	the Exchange Rate in effect immediately after such distribution;

FMV₀	=	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of shares of Common Stock applicable to one share of Common Stock over the first ten consecutive Trading Day period after the effective date of the Spin-Off; and

MP₀	=	the average of the Last Reported Sale Prices of the Common Stock over the first ten consecutive Trading Day period after the effective date of the Spin-Off.

Rights or warrants distributed by Parent to all holders of Common Stock, entitling the holders thereof to subscribe for or purchase shares of Common Stock (either initially or under

D-19

certain circumstances), which rights or warrants, until the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such shares of Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of shares of Common Stock, shall be deemed not to have been distributed for purposes of this Section 8.04 (and no adjustment to the Exchange Rate under this Section 8.04 will be required) until the occurrence of the earliest Trigger Event, whereupon such rights and warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Exchange Rate shall be made under this Section 8.04(c). If any such right or warrant, including any such existing rights or warrants distributed prior to the date of this Annex D of the Twelfth Supplemental Indenture, are subject to events, upon the occurrence of which such rights or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and record date with respect to new rights or warrants with such rights (and a termination or expiration of the existing rights or warrants without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Exchange Rate under this Section 8.04 was made, (1) in the case of any such rights or warrants that shall all have been redeemed or repurchased without exercise by any holders thereof, the Exchange Rate shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder or holders of Common Stock with respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights or warrants that shall have expired or been terminated without exercise by any holders thereof, the Exchange Rate shall be readjusted as if such rights and warrants had not been issued.

D-20

the Dividend Threshold Amount for such quarter, the Exchange Rate shall be adjusted based on the following formula:

where

ER₀	=	the Exchange Rate in effect immediately prior to the Ex-Date for such distribution;

ER¢	=	the Exchange Rate in effect as of the Ex-Date for such distribution;

SP₀	=	the average of the Last Reported Sale Prices of the Common Stock over the period of ten consecutive Trading Days ending the Business Day immediately preceding the record date (as defined in clause (f) of this Section) for such distribution (or, if earlier, the Ex-Date relating to such distribution);

T	=	the dividend threshold amount (“Dividend Threshold Amount”), which amount shall initially be $0.3360 per quarter and which shall be appropriately adjusted from time to time for any stock dividends on, or subdivisions or combinations of, Common Stock; provided, that if an Exchange Rate adjustment is required to be made as a result of a distribution that is not a quarterly dividend either in whole or in part, the Dividend Threshold Amount shall be deemed to be zero; and

C	=	the amount in cash per share that Parent distributes to holders of Common Stock.

Such adjustment shall become effective immediately after 5:00 p.m., New York City time, on the record date for such dividend or distribution; provided that if the portion of the cash so distributed applicable to one share of Common Stock is equal to or greater than SP₀ above, in lieu of the foregoing adjustment, adequate provision shall be made so that each Noteholder shall have the right to receive upon exchange of a Note (or any portion thereof) the amount of cash such Holder would have received had such Holder owned a number of shares equal to the Exchange Rate on the record date. If such dividend or distribution is not so paid or made, the Exchange Rate shall again be adjusted to be the Exchange Rate that would then be in effect if such dividend or distribution had not been declared.

For the avoidance of doubt, for purposes of this Section 8.04(d), in the event of any reclassification of the Common Stock, as a result of which the Notes become exhangeable into more than one class of Common Stock, if an adjustment to the Exchange Rate is required pursuant to this Section 8.04(d), references in this Section to one share of Common Stock or Last Reported Sale Price of one share of Common Stock shall be deemed to refer to a unit or to the price of a unit consisting of the number of shares of each class of Common Stock into which the Notes are then exchangeable equal to the number of shares of such class issued in respect of one

D-21

share of Common Stock in such reclassification. The above provisions of this paragraph shall similarly apply to successive reclassifications.

where

ER₀	=	the Exchange Rate in effect on the date such tender or exchange offer expires;

ER¢	=	the Exchange Rate in effect on the day next succeeding the date such tender or exchange offer expires;

AC	=	the aggregate value of all cash and any other consideration (as determined by the Board of Trustees) paid or payable for shares purchased in such tender or exchange offer;

OS₀	=	the number of shares of Common Stock outstanding immediately prior to the date such tender or exchange offer expires;

OS¢	=	the number of shares of Common Stock outstanding immediately after the date such tender or exchange offer expires; and

SP¢	=	the average of the Last Reported Sale Prices of the Common Stock over the ten consecutive Trading Day period commencing on the Trading Day next succeeding the date such tender or exchange offer expires,

D-22

D-23

Security Register, within thirty (30) days of the effective date of such adjustment. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

Notwithstanding the foregoing provisions of this Section 8.04, in no event will the total number of shares of Common Stock issuable upon exchange exceed 33.3134 per $1,000 principal amount of Notes (subject to adjustment in the same manner or as set forth in clauses (a), (b) and (c) of this Section 8.04).

Section 8.05 Sufficient Shares to be Delivered. To the extent the Company elects to deliver shares of Common Stock, and subject to Section 8.02(k), the Company shall provide, free from preemptive rights, sufficient shares of Common Stock to provide for exchange of the Notes from time to time as such Notes are presented for exchange.

Section 8.06 Effect of Reclassification, Consolidation, Merger or Sale. If any of the following events occur, namely (i) any reclassification or change of the outstanding Common Stock (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a split, subdivision or combination), (ii) any consolidation, merger or combination of Parent with another Person, or (iii) any sale or conveyance of all or substantially all of the property and assets of Parent to any other Person, in each case as a result of which holders of Common Stock shall be entitled to receive stock, other securities or other property, assets or cash (or any combination thereof) with respect to or in exchange for such shares of Common Stock (any such event a “Reorganization Event”), then:

(a) the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture (which, as evidenced in an Opinion of Counsel delivered to the Trustee, shall comply with the Trust Indenture Act as in force at the date of execution of such supplemental indenture if such supplemental indenture is then required to so comply) providing for the exchange and settlement of the Notes as set forth in this Annex D of the Twelfth Supplemental Indenture. Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article and the Trustee may conclusively rely on the determination by the Company of the equivalency of such adjustments. If, in the case of any Reorganization Event, the Reference Property includes shares of stock or other securities and assets of a corporation other than the successor or purchasing corporation, as the case may be, in such reclassification, change, consolidation, merger, combination, sale or conveyance, then such supplemental indenture shall also be executed by such other corporation and shall contain such additional provisions to protect the interests of the Holders of the Notes as the Board of Trustees shall reasonably consider necessary by reason of the foregoing, including to the extent required by the Board of Trustees and practicable the provisions providing for the repurchase rights set forth in Article IX herein.

D-24

In the event the Company shall execute a supplemental indenture pursuant to this Section 8.06, the Company shall, in addition to the Officers’ Certificate and Opinion of Counsel required by Section 102 of the Base Indenture, file with the Trustee an Officers’ Certificate briefly stating the kind or amount of cash, securities or property or asset that will constitute the Reference Property after any such Reorganization Event, any adjustment to be made with respect thereto, and the Trustee shall promptly mail notice thereof to all Noteholders.

(b) Notwithstanding the provisions of Section 8.02(a), and subject to the provisions of Section 8.01, at the effective time of such Reorganization Event, the right to exchange each $1,000 principal amount of Notes will be changed to a right to exchange such Note by reference to the kind and amount of stock, other securities or other property, assets or cash (or any combination thereof) that such holder of Notes would have owned immediately after such Reorganization Event if such holder had exchanged their Notes immediately prior to such Reorganization Event (the “Reference Property”). For purposes of the foregoing, where a Reorganization Event involves consideration based upon any form of stockholder election, the consideration will be deemed to be the weighted average of the types and amounts of consideration received by the holders of shares of Common Stock that affirmatively make such an election. Parent shall not become a party to any such transaction unless its terms are consistent with the preceding. None of the foregoing provisions shall affect the right of a Holder of Notes to exchange its Notes in accordance with the provisions of Article VIII hereof prior to the effective date of a Reorganization Event. For the avoidance of doubt, adjustments to the Exchange Rate set forth under Section 8.04 do not apply to distributions to the extent that the right to exchange Notes has been changed into the right to exchange into Reference Property.

(d) The above provisions of this Section shall similarly apply to successive Reorganization Events.

(a) Parent shall declare a dividend (or any other distribution) on its Common Stock that would require an adjustment in the Exchange Rate pursuant to Section 8.04; or

(b) Parent shall authorize the granting to all of the holders of its Common Stock of rights or warrants to subscribe for or purchase any share of any class or any other rights or warrants;

CUSIP No. 743410 AY8

PROLOGIS, a real estate investment trust organized and existing under the laws of the State of Maryland (herein called the “Company,” which term includes any successor corporation under the Indenture referred to on the reverse hereof), for value received hereby promises to pay to [CEDE & CO.], or registered assigns, the principal sum of [____] ($[____]) or such other principal amount as shall be set forth on the Schedule I hereto on March 15, 2015.

This Security shall bear interest at the rate of 3.25% per year from March 16, 2010, or from the most recent date to which interest had been paid or provided.

Interest payable on each Interest Payment Date shall equal the amount of interest accrued from, and including the immediately preceding Interest Payment Date (or from and including March 16, 2010, if no interest has been paid hereon) to but excluding such Interest Payment Date.

Payment of the principal and interest, on this Security will be made at the office or agency of the Company maintained for that purpose in the Borough of Manhattan, City of New York, or elsewhere as provided in the Indenture, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that at the option of the Company, payment of interest, may be made by (i) check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register or (ii) transfer to an account of the Person entitled thereto located inside the United States; provided further, however, that, with respect to any Holder of Securities with an aggregate principal amount in excess of $1,000,000, at the application of such Holder in writing to the Company, interest on such Holder’s Securities shall be paid by wire transfer in immediately available funds to such Holder’s account in the United States supplied by such Holder from time to time to the Trustee and Paying Agent (if different from the Trustee) not later than the applicable record date.

PROLOGIS
3.25% Convertible Senior Notes due 2015

This Security is one of a duly authorized issue of Securities of the Company, designated as its 3.25% Convertible Senior Notes due 2015 (herein called the “Securities”), issued under and pursuant to an Indenture dated as of March 1, 1995, as supplemented with respect to the Securities by the Second Supplemental Indenture, dated as of November 2, 2005, the Ninth Supplemental Indenture, dated as of October 1, 2009 and the Tenth Supplemental Indenture, dated as of March 16, 2010 (as so supplemented, herein called the “Indenture”), between the Company and U.S. Bank National Association (herein called the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Securities. Additional Securities may be issued in an unlimited aggregate principal amount, subject to certain conditions specified in the Indenture. Capitalized terms used but not defined herein shall have the meanings ascribed to them in the Indenture.

Prior to March 15, 2015, the Company may not redeem the Securities except to preserve the Company’s status as a real estate investment trust as described in Section 3.01 of the Tenth Supplemental Indenture. Any such redemption shall be upon at least 30 days’ and no more than 60 days’ notice to Holders of the Securities.

Subject to the terms and conditions of the Indenture, the Company will make all payments and deliveries in respect of the Fundamental Change Repurchase Price, the Redemption Price and the principal amount on the Maturity Date, as the case may be, to the Holder who surrenders a Security to a Paying Agent to collect such payments in respect of the Security. The Company will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts.

The Indenture contains provisions permitting the Company and the Trustee in certain circumstances, without the consent of the Holders of the Securities, and in other circumstances, with the consent of the Holders of not less than a majority in principal amount of the Securities at the time Outstanding, evidenced as in the Indenture provided, to execute supplemental indentures adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or modifying in any manner the rights of the Holders of the Securities; provided, however, that no such supplemental indenture shall make any of the changes set forth in Section 6.02 of the Tenth Supplemental Indenture, without the consent of each Holder of an Outstanding Security affected thereby. It is also provided in the Indenture that, prior to any declaration accelerating the maturity of the Securities, the Holders of a majority in principal amount of the Securities at the time Outstanding may on behalf of the Holders of all of the Securities waive any past default or Event of Default under the Indenture and its

D-Exh A-4

consequences except as provided in the Indenture. Any such consent or waiver by the Holder of this Security (unless revoked as provided in the Indenture) shall be conclusive and binding upon such Holder and upon all future Holders and owners of this Security and any Securities which may be issued in exchange or substitution hereof, irrespective of whether or not any notation thereof is made upon this Security or such other Securities.

The Securities are not subject to redemption through the operation of any sinking fund. Section 1004, Section 1006, Section 1007 and Section 1011 of the Indenture shall not apply to the Securities.

Subject to the provisions of the Indenture, the Holder hereof has the right, at its option, at any time prior to the close of business on the Trading Day immediately preceding the Maturity Date, to convert any Securities or portion thereof which is $1,000 or an integral multiple thereof, into Common Shares at the Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture, upon surrender of this Security, together with a Notice of Conversion, a form of which is attached to this Security, as provided in the Indenture and this Security, to the Company at the office or agency of the Company maintained for that purpose in the Borough of Manhattan, City of New York or elsewhere as provided in the Indenture, and, unless the shares issuable on conversion are to be issued in the same name as this Security, duly endorsed by, or accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the Holder or by his duly authorized attorney. The initial Conversion Rate is 57.8503 shares for each $1,000 principal amount of Securities. No fractional Common Shares will be issued upon any conversion, but an adjustment in cash will be paid to the Holder, as provided in the Indenture, in respect of any fraction of a share which would otherwise be

D-Exh A-5

issuable upon the surrender of any Security or Securities for conversion. No adjustment shall be made for dividends or any shares issued upon conversion of such Security except as provided in the Indenture.

Upon due presentment for registration of transfer of this Security at the office or agency of the Company in the Borough of Manhattan, City of New York, a new Security or Securities of authorized denominations for an equal aggregate principal amount will be issued to the transferee in exchange thereof, subject to the limitations provided in the Indenture, without charge except for any tax, assessments or other governmental charge imposed in connection therewith.

Terms used in this Security and defined in the Indenture are used herein as therein defined.
