(A) the Registrar will deliver notice of such request to the Company and the Trustee, which notice will identify the owner of the beneficial interest to be exchanged, the aggregate principal amount of such beneficial interest and the CUSIP of the relevant Global Security, in each case if and as such information is provided to the Registrar by the Depository;

(B) the Company, in accordance with Section 2.04 of the Base Indenture, will promptly execute, and, upon receipt of a Company Request, the Trustee, in accordance with Section 2.04 of the Base Indenture, will promptly authenticate and deliver to such owner, for the beneficial interest so exchanged by such owner, Physical Securities registered in such owner’s name having an aggregate principal amount equal to the aggregate principal amount of such beneficial interest and bearing any legends that such Physical Securities are required to bear under the Indenture; and

(C) the Registrar, in accordance with the Applicable Procedures, will cause the principal amount of such Global Security to be decreased by the aggregate principal amount of the beneficial interest so exchanged. If all of the beneficial interests in a Global Security are so exchanged, such Global Security will be deemed surrendered to the Trustee for cancellation, and the Trustee will cause such Global Security to be cancelled in accordance with the Applicable Procedures.

(A) the Company will deliver notice of such request to the Registrar and the Trustee, which notice will identify each owner of a beneficial interest to be exchanged, the aggregate principal amount of each such beneficial interest and the CUSIP of the relevant Global Security;

(B) the Company, in accordance with Section 2.04 of the Base Indenture, will promptly execute, and, upon receipt of a Company Request, the Trustee, in accordance with Section 2.04 of the Base Indenture, will promptly authenticate and deliver to each such beneficial owner, Physical Securities registered in such beneficial owner’s name having an aggregate principal amount equal to the aggregate principal amount of its exchanged beneficial interest and bearing any legends that such Physical Securities are required to bear under the Indenture and any applicable law; and

(C) the Registrar, in accordance with the Applicable Procedures, will cause the principal amount of each relevant Global Security to be decreased by the aggregate principal amount of the beneficial interests so exchanged. If all of the beneficial interests in a Global Security are so exchanged, such Global Security will be deemed surrendered to the Trustee for cancellation, and the Trustee will cause such Global Security to be cancelled in accordance with the Applicable Procedures.

In each of the cases described in clauses (1), (2) and (3) above, the Company may rely on the Depository to provide all names of beneficial owners and their respective principal amounts beneficially owned and may issue Physical Securities registered in the names and amounts so provided by the Depository.

(d) Physical Securities. Except to the extent otherwise provided in Section 2.03(a) hereof, Physical Securities may be transferred or exchanged in accordance with Section 2.08 of the Base Indenture.

(a) In General. Each Security will accrue cash interest at a rate equal to 4.125% per annum from the most recent date to which interest has been paid or duly provided for, or, if no interest has been paid or duly provided for, the Issue Date. Interest on a Security will cease to accrue upon the earliest of the Maturity Date, subject to the provisions of Article 3 hereof, any Fundamental Change Purchase Date or Redemption Date for such Security, and subject to the provisions of Article 4 hereof, any Conversion Date for such Security. Interest on any Security will be payable semi-annually in arrears on each Interest Payment Date, beginning March 1, 2018, to the Holder of such Security as of the Close of Business on the Regular Record Date immediately preceding the applicable Interest Payment Date. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. Pursuant to Section 6.04 hereof, in certain circumstances, the Company may be obligated to pay Holders Supplementary Interest.

The Securities will mature on the Maturity Date, and on the Maturity Date, each Holder of a then Outstanding Security will be entitled on such date to receive $1,000 in cash for each $1,000 in principal amount of then Outstanding Securities held, together with accrued and unpaid interest to, but not including, the Maturity Date on such then Outstanding Securities.

Notwithstanding anything to the contrary, if the Maturity Date or any Interest Payment Date, Fundamental Change Purchase Date, Redemption Date or any Conversion Date falls, or if any payment, delivery, notice or other action by the Company is otherwise due, on a day that is not a Business Day, then any action to be taken on such date need not be taken on such date, but may be taken on the immediately following Business Day with the same force and effect as if taken on such date, and no additional interest will accrue and no Default shall occur on account of such delay.

(b) Method of Payment. The Company will pay the principal of, the Fundamental Change Purchase Price, REIT Redemption Price or Optional Redemption Price for, and any cash in lieu of fractional shares of Common Stock upon the conversion of, any Physical Security to the Holder of such Security in cash at the designated office of the Paying Agent in the borough of Manhattan in The City of New York, New York, prior to 10:00 a.m. on the relevant payment or settlement date, as the case may be. The Company will pay any interest on any Physical Security to the Holder of such Security (i) if such Holder holds $2,000,000 or less aggregate principal amount of Securities, by check mailed to such Holder’s registered address, and (ii) if such Holder holds more than $2,000,000 aggregate principal amount of Securities, (A) by check mailed to such Holder’s registered address or, (B) if such Holder delivers to the Registrar a written request that the Company make such payments by wire transfer to an account of such Holder within the United States, for each interest payment corresponding to each Regular Record Date occurring during the period beginning on the date on which such Holder delivered such request and ending on the date, if any, on which such Holder delivers to the Registrar a written instruction to the contrary, by wire transfer of immediately available funds to the account specified by such Holder. The Company will pay the principal of, interest on, the Fundamental Change Purchase Price, REIT Redemption Price or Optional Redemption Price for, and any cash in lieu of fractional shares of Common Stock upon the conversion of, any Global Security to the Depository by wire transfer of immediately available funds on the relevant payment date in accordance with Applicable Procedures.

(c) Defaulted Payments. The Company shall pay any interest on the Securities that is payable, but is not punctually paid or duly provided for, on the applicable Interest Payment Date, in accordance with Section 2.13 of the Base Indenture.

(a) No Redemption. Article III of the Base Indenture shall not apply with respect to the Securities.

Section 3.02 Purchase at Option of Holders upon a Fundamental Change. (a) If a Fundamental Change occurs, then each Holder shall have the right, at such Holder’s option, to require the Company to purchase for cash all of such Holder’s Securities, or any portion thereof such that the remaining principal amount of each Security that is not purchased in full equals $1,000 or an integral multiple of $1,000 in excess thereof, on a date (the “Fundamental Change Purchase Date”) specified by the Company that is not less than 20 calendar days or more than 35 calendar days following the date on which the Company delivers the Fundamental Change Company Notice, at a purchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest thereon, if any, to, but excluding, the Fundamental Change Purchase Date (the “Fundamental Change Purchase Price”); provided, however, that if the Company purchases a Security on a Fundamental Change Purchase Date that is after a Regular Record Date and on or prior to the Interest Payment Date corresponding to such Regular Record Date, the Company shall instead pay such accrued and unpaid interest on such Security on the Interest Payment Date to the Holder of record of such Security as of such Regular Record Date.

Purchases of Securities under this Section 3.02 shall be made, at the option of the Holder thereof, upon:

(1) if the Securities to be purchased are Physical Securities, delivery to the Paying Agent by the Holder of a duly completed notice (the “Fundamental Change Purchase Notice”) in the form set forth in Attachment 2 to the Form of Security attached hereto as Exhibit A and of the Securities, duly endorsed for transfer, on or before the Close of Business on the Business Day immediately preceding the Fundamental Change Purchase Date, subject to extensions to comply with applicable law (the “Fundamental Change Expiration Time”); and

(2) if the Securities to be purchased are Global Securities, delivery of the Securities, by book-entry transfer, in compliance with the Applicable Procedures of the Depository and the satisfaction of any other requirements of the Depository in connection with tendering beneficial interests in a Global Security for purchase, by the Fundamental Change Expiration Time.

The Fundamental Change Purchase Notice in respect of any Securities to be purchased shall state:

(2) the portion of the principal amount of such Securities, which must be such that the principal amount that is not to be purchased of each Security that is not to be purchased in full equals $1,000 or an integral multiple of $1,000 in excess thereof; and

(3) that such Securities are to be purchased by the Company pursuant to the applicable provisions of the Securities and the Indenture.

Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Fundamental Change Purchase Notice contemplated by this Section 3.02 shall have the right to withdraw, in whole or in part, such Fundamental Change Purchase Notice at any time prior to the Fundamental Change Expiration Time by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 3.04.

The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Purchase Notice or written notice of withdrawal thereof.

(b) On or before the 20th calendar day after the occurrence of a Fundamental Change, the Company shall provide to all Holders of the Securities, the Trustee and the Paying Agent (in the case of any Paying Agent other than the Trustee) a notice (the “Fundamental Change Company Notice”) of the occurrence of such Fundamental Change and of the purchase right at the option of the Holders arising as a result thereof. Such notice shall be sent by first class mail or, in the case of any Global Securities, in accordance with the procedures of the Depository for providing notices. Simultaneously with providing such Fundamental Change Company Notice, the Company shall publish this information in a newspaper of general circulation in The City of New York or publish the information on the Company’s website or through such other public medium as the Company may use at that time.

(3) the last date on which a Holder of Securities may exercise the purchase right pursuant to this Article 3;

(6) the name and address of the Paying Agent and the Conversion Agent, if applicable;

(7) the applicable Conversion Rate and any adjustments to the applicable Conversion Rate;

(8) that the Securities with respect to which a Fundamental Change Purchase Notice has been delivered by a Holder may be converted only if the Holder withdraws the Fundamental Change Purchase Notice in accordance with the Indenture;

(9) that the Holder shall have the right to withdraw any Securities surrendered for purchase prior to the Fundamental Change Expiration Time; and

(10) the procedures that Holders must follow to require the Company to purchase their Securities.

No failure of the Company to give the foregoing notices and no defect therein shall limit the purchase rights of the Holders of Securities or affect the validity of the proceedings for the purchase of the Securities pursuant to this Section 3.02.

(c) Notwithstanding the foregoing, there shall be no purchase of any Securities pursuant to this Section 3.02 if the principal amount of the Securities has been accelerated, and such acceleration has not been rescinded, on or prior to the Fundamental Change Purchase Date (except in the case of an acceleration resulting from a Default by the Company

in the payment of the Fundamental Change Purchase Price with respect to such Securities). The Paying Agent will promptly return to the respective Holders thereof any Physical Securities held by it during the acceleration of the Securities (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Purchase Price with respect to such Securities) and shall deem to be cancelled any instructions for book-entry transfer of the Securities in compliance with the procedures of the Depository, in which case, upon such return or cancellation, as the case may be, the Fundamental Change Purchase Notice with respect thereto shall be deemed to have been withdrawn.

(d) Notwithstanding the other provisions of this Article 3, the Company will not be required to make an offer to purchase the Securities upon a Fundamental Change if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements in the Indenture and such third party purchases all Securities properly tendered and not validly withdrawn under its offer.

Section 3.03 Effect of Fundamental Change Purchase Notice. Upon receipt by the Paying Agent of a Fundamental Change Purchase Notice specified in Section 3.02, the Holder of the Security in respect of which such Fundamental Change Purchase Notice was given shall (unless such Fundamental Change Purchase Notice is withdrawn in accordance with Section 3.04) thereafter be entitled to receive solely the Fundamental Change Purchase Price in cash with respect to such Security (and any previously accrued and unpaid interest on such Security). Such Fundamental Change Purchase Price shall be paid to such Holder, subject to receipt of funds by the Paying Agent, on the later of (x) the applicable Fundamental Change Purchase Date (provided the conditions in Section 3.02 have been satisfied) and (y) the time of delivery or book-entry transfer of such Security to the Paying Agent by the Holder thereof in the manner required by Section 3.02, subject in each case to extensions to comply with applicable law.

Section 3.04 Withdrawal of Fundamental Change Purchase Notice. A Fundamental Change Purchase Notice may be withdrawn (in whole or in part) by means of a written notice of withdrawal delivered to the Paying Agent in accordance with the Fundamental Change Company Notice at any time prior to the Fundamental Change Expiration Time, specifying:

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

(2) if Physical Securities have been issued, the certificate numbers of the withdrawn Securities; and

(3) the principal amount, if any, of each Security that remains subject to the Fundamental Change Purchase Notice, which must be such that the principal amount not to be purchased equals $1,000 or an integral multiple of $1,000 in excess thereof;

provided, however, that if the Securities are Global Securities, the notice must comply with Applicable Procedures of the Depository.

The Paying Agent will promptly return to the respective Holders thereof any Physical Securities with respect to which a Fundamental Change Purchase Notice has been withdrawn in compliance with the provisions of this Section 3.04.

Section 3.05 Deposit of Fundamental Change Purchase Price. Prior to 10:00 a.m., New York City time, on the Fundamental Change Purchase Date, the Company shall deposit with the Paying Agent (or, if the Company or a Subsidiary or an Affiliate of either of them is acting as the Paying Agent, shall segregate and hold in trust as provided herein) an amount of money (in immediately available funds if deposited on such Business Day) sufficient to pay the Fundamental Change Purchase Price of all the Securities or portions thereof that are to be purchased as of the Fundamental Change Purchase Date. If the Paying Agent holds cash sufficient to pay the Fundamental Change Purchase Price of the Securities for which a Fundamental Change Purchase Notice has been tendered and not withdrawn in accordance with the Indenture on the Fundamental Change Purchase Date, then as of such Fundamental Change Purchase Date, (a) such Securities will cease to be Outstanding and interest will cease to accrue thereon (whether or not book-entry transfer of such Securities is made or such Securities have been delivered to the Paying Agent) and (b) all other rights of the Holders in respect thereof will terminate (other than the right to receive the Fundamental Change Purchase Price upon delivery or book-entry transfer of such Securities).

Section 3.06 Securities Purchased in Whole or in Part. Any Security that is to be purchased, whether in whole or in part, shall be surrendered at the office of the Paying Agent (with, if the Company or the Trustee so requires in the case of Physical Securities, 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 such Holder’s attorney duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security, without service charge, a new Security or Securities, of any authorized denomination as requested by such Holder in aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Security so surrendered that is not purchased.

Section 3.07 Covenant To Comply with Applicable Laws upon Purchase of Securities. In connection with any offer to purchase Securities under Section 3.02, the Company shall, in each case if required by law, (i) comply with Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act that may then be applicable, (ii) file a Schedule TO or any other required schedule under the Exchange Act and (iii) otherwise comply with all federal and state securities laws applicable to the Company in connection with such purchase offer, in each case, so as to permit the rights and obligations under Section 3.02 to be exercised in the time and in the manner specified in Section 3.02.

Section 3.08 Repayment to the Company. To the extent that the aggregate amount of cash deposited by the Company pursuant to Section 3.05 exceeds the aggregate Fundamental Change Purchase Price of the Securities or portions thereof that the Company is obligated to purchase as of the Fundamental Change Purchase Date, then, following the Fundamental Change Purchase Date, the Paying Agent shall promptly return any such excess to the Company.

Section 4.01 Right To Convert. (a) Upon compliance with the provisions of the Indenture, at any time prior to the Close of Business on the second Scheduled Trading Day immediately preceding the Maturity Date, unless such securities have been redeemed in accordance with Sections 3.02, 11.01(a) or 11.01(b), or repurchased by the Company, the Holder of any Securities not previously repurchased or redeemed shall have the right, at such

Holder’s option, to convert its Securities, or any portion thereof which is a multiple of $1,000, into Common Stock, as provided in Section 4.03, by surrender of such Securities so to be converted in whole or in part, together with any required funds, under the circumstances and in the manner described in this Article 4.

(b) Notwithstanding any other provision of the Securities or the Indenture, no Holder of Securities will be entitled to receive Common Stock following conversion of such Securities to the extent that receipt of such Common Stock would cause such Holder (either directly or after application of certain constructive ownership rules) to exceed the ownership limits contained in the Company’s charter. Any purported delivery of shares of Common Stock upon conversion of Securities shall be void and have no effect to the extent (but only to the extent) that such delivery would result in the converting holder violating the restrictions on ownership and transfer of the Common Stock contained in the Company’s charter. Any attempted conversion of Securities that would result in the issuance of shares of Common Stock in violation of these charter restrictions shall be void to the extent of the number of shares of Common Stock that would cause such violation, and the related Securities, or portions, thereof shall be returned to the Holder as promptly as practical. The Company shall not have any further obligation to the Holder with respect to such voided conversion and such Securities shall be treated as if they had not been submitted for conversion.

(c) A Security in respect of which a Holder has delivered a Fundamental Change Purchase Notice exercising such Holder’s right to require the Company to purchase such Security pursuant to Section 3.02 may be converted only if such Fundamental Change Purchase Notice is properly withdrawn in accordance with, and within the time periods set forth in, Section 3.04.

(d) If the Company delivers a Redemption Notice, (a) a Holder may convert all or any portion of its Securities called for REIT Redemption or Optional Redemption, as applicable, on or after the date of such Redemption Notice at any time prior to the Close of Business on the Business Day immediately preceding the Redemption Date and (b) in the event of an Optional Redemption, if the Conversion Date falls prior to the Regular Record Date immediately preceding the Maturity Date, such Holder shall receive, in addition to the Conversion Price due upon conversion of such Securities and accrued and unpaid interest to (but excluding) the Conversion Date, the Make-Whole Premium.

(a) Each Security shall be convertible at the office of the Conversion Agent and, if applicable, in accordance with the Applicable Procedures of the Depository.

(b) To exercise the conversion privilege with respect to a beneficial interest in a Global Security, the Holder must complete the appropriate instruction form for conversion pursuant to the Depository’s book-entry conversion program, furnish appropriate endorsements and transfer documents if required by the Company or the Conversion Agent, and pay the funds, if any, required by Section 4.02(f) and any taxes or duties if required pursuant to Section 4.02(h), and the Conversion Agent must be informed of the conversion in accordance with the customary practice of the Depository.

To exercise the conversion privilege with respect to any Physical Securities, the Holder of such Physical Securities shall:

(1) complete and manually sign a conversion notice in the form set forth in the Form of Notice of Conversion (the “Conversion Notice”) or a facsimile of the Conversion Notice;

(2) deliver the Conversion Notice, which is irrevocable, and the Security to the Conversion Agent;

(5) if required, pay all transfer or similar taxes as set forth in Section 4.02(g).

If, upon conversion of a Security, any shares of Common Stock are to be issued to a person other than the Holder of such Security, the related Conversion Notice shall include such other person’s name and address.

If a Security is subject to a Fundamental Change Purchase Notice, such Security may not be converted unless such Fundamental Change Purchase Notice is withdrawn in accordance with Section 3.04 hereof prior to the relevant Fundamental Change Expiration Time.

For any Security, the first Business Day on which the Holder of such Security satisfies all of the applicable requirements set forth above with respect to such Security and on which conversion of such Security is not otherwise prohibited under the Indenture shall be the “Conversion Date” with respect to such Security.

Each conversion shall be deemed to have been effected as to any such Securities (or portion thereof) surrendered for conversion at the Close of Business on the applicable Conversion Date, and the person in whose name the certificate for any shares of Common Stock delivered upon conversion is registered shall be treated as a stockholder of record as of the Close of Business on such Conversion Date.

(c) Endorsement. Any Securities surrendered for conversion shall, unless shares of Common Stock issuable on conversion are to be issued in the same name as the registration of such Securities, be duly endorsed by, or be accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the Holder or its duly authorized attorney.

(d) Physical Securities. If any Securities in a denomination greater than $1,000 shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to the Holder of the Securities so surrendered, without charge, new Securities in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Securities.

(e) Global Securities. Upon the conversion of a beneficial interest in Global Securities, the Conversion Agent shall make a notation in its records as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversions of Securities effected through any Conversion Agent other than the Trustee.

(f) Interest Due Upon Conversion. If a Holder converts a Security after the Close of Business on a Regular Record Date but prior to the Open of Business on the Interest Payment Date corresponding to such Regular Record Date, such Holder must accompany such Security with an amount of cash equal to the amount of interest that will payable on such Security on the corresponding Interest Payment Date; provided, however, that a Holder need not make such payment (1) if the Conversion Date follows the Regular Record Date immediately preceding the Maturity Date; (2) if the Company has specified a Redemption Date that occurs following a Regular Record Date but occurs on or prior to the corresponding Interest Payment Date; (3) if the Company has specified a Fundamental Change Purchase Date that is after a Regular Record Date and on or prior to the corresponding Interest Payment Date and the Holder converts its Security after the Close of Business on such Regular Record Date and on or prior to the Open of Business on such Interest Payment Date; or (4) to the extent of any overdue interest, if any overdue interest exists at the time of conversion with respect to such Security.

(g) If a Holder surrenders Securities for conversion following a Redemption Notice and prior to the related Redemption Date, interest shall continue to accrue until the date on which the Company delivers the consideration due in respect of such Securities, and will be payable to the Holder together with the consideration due (without duplication of any interest such Holder is otherwise entitled to by virtue of being the Holder of Securities on an applicable Regular Record Date).

(h) Taxes Due Upon Conversion. If a Holder converts a Security, the Company will pay any documentary, stamp or similar issue or transfer tax due on the issue of any shares of the Common Stock upon the conversion, unless the tax is due because the Holder requests that any shares be issued in a name other than the Holder’s name, in which case the Holder will pay that tax.

(i) Cash Payments in Lieu of Fractional Shares. No fractional shares of Common Stock or scrip certificates representing fractional shares shall be issued upon conversion of Securities. If more than one Security shall be surrendered for conversion at one time by the same Holder, the number of full shares that shall be issuable upon conversion shall be computed on the basis of the aggregate principal amount of the Securities (or specified portions thereof to the extent permitted hereby) so surrendered. If any fractional share of Common Stock would be issuable upon the conversion of any Security or Securities, the Company shall make a payment therefor in cash to the Holder of Securities equal to the product of (i) such fraction of a share and (ii) the Last Reported Sale Price of the Common Stock on the relevant Scheduled Trading Day (or, if the Scheduled Trading Day is not a Trading Day, the next following Trading Day).

(a) Upon conversion of any Securities, subject to Sections 4.01, 4.02 and this Section 4.03, the Company shall satisfy its obligation upon conversion (the “Conversion Obligation”) by delivery of the shares (and, if applicable, payment of the cash) described under Section 4.03(b) below.

(b) Upon conversion of Securities, the Company shall deliver, in respect of each $1,000 principal amount of Securities tendered for conversion in accordance with their terms:

(1) a number of shares of Common Stock equal to (a) (i) the aggregate principal amount of Securities to be converted divided by (ii) $1,000, multiplied by (b) the applicable Conversion Rate on the date the converting Holder is treated as a record owner of the Common Stock pursuant to the last paragraph of Section 4.02(b); and

(2) an amount in cash in lieu of any fractional shares of Common Stock as provided in Section 4.02(i).

(c) Delivery of the shares of Common Stock (and, if applicable, payment of the cash) pursuant to Section 4.03(b) shall be made by the Company on or prior to the third Business Day immediately following the Conversion Date to the holder of a Security surrendered for conversion, or such holder’s nominee or nominees, and the Company shall deliver to the Conversion Agent or to such holder, or such holder’s nominee or nominees, certificates or a book-entry transfer through the Depository for the number of full shares of Common Stock to which such holder shall be entitled as part of such Conversion Obligation. Notwithstanding the foregoing, delivery of the shares of Common Stock (and, if applicable, payment of the cash) pursuant to Section 4.03(b) with respect to any Conversion Date that occurs on or after the Regular Record Date immediately preceding the Maturity Date shall be made by the Company on the Maturity Date.

(d) Settlement of Accrued Interest and Deemed Payment of Principal. If a Holder converts a Security, the Company will not adjust the Conversion Rate to account for any accrued and unpaid interest on such Security, and the Company’s delivery of shares of Common Stock (and cash in lieu of fractional shares, if any) into which a Security is convertible will be deemed to satisfy and discharge in full the Company’s obligation to pay the principal of, and accrued and unpaid interest, if any, on, such Security to, but excluding, the Conversion Date; provided, however, that if a Holder converts a Security after a Regular Record Date and prior to the Open of Business on the corresponding Interest Payment Date, the Company will still be obligated to pay the interest due on such Interest Payment Date to the Holder of such Security on such Regular Record Date (provided the Holder makes the interest payment upon conversion if so required by Section 4.02(f)).

As a result, except as otherwise provided in the proviso to the immediately preceding sentence, any accrued and unpaid interest with respect to a converted Security will be deemed to be paid in full rather than cancelled, extinguished or forfeited. In no event will a Holder be entitled to receive any dividend or other distribution with respect to any Common Stock issued on conversion of such Holder’s Securities if the applicable Conversion Date is after the Regular Record Date for such dividend or distribution.

(e) Notices. Whenever a Conversion Date occurs with respect to a Security, the Conversion Agent will, as promptly as possible, and in no event later than the Business Day immediately following such Conversion Date, deliver to the Company and the Trustee, if it is not then the Conversion Agent, notice that a Conversion Date has occurred, which notice will state such Conversion Date, the principal amount of Securities converted on such Conversion Date and the names of the Holders that converted Securities on such Conversion Date.

The Conversion Rate will be adjusted as described in this Section 4.04, except that the Company shall not make any adjustment to the Conversion Rate if Holders participate (other than in the case of a share split or share combination), at the same time and upon the same terms as holders of the Common Stock and as a result of holding the Securities, in any of the transactions described below without

having to convert their Securities, as if they held a number of shares of Common Stock equal to the applicable Conversion Rate, multiplied by the principal amount (expressed in thousands) of Securities held by such Holder.

(a) If the Company exclusively issues shares of Common Stock as a dividend or distribution on all or substantially all outstanding shares of the Common Stock, or if the Company effects a share split or share combination, the Conversion Rate will be adjusted based on the following formula:

Any adjustment made pursuant to this Section 4.04(a) shall become effective immediately after the Close of Business on the record date for such dividend or distribution, or immediately after the Open of Business on the effective date for such share split or share combination. If any dividend or distribution of the type described in this Section 4.04(a) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

(b) If the Company issues to all or substantially all holders of the outstanding Common Stock any rights, options or warrants entitling them, for a period of not more than forty-five (45) calendar days after the record date of such issuance, to subscribe for or purchase shares of the Common Stock, at a price per share less than the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, the Conversion Rate will be increased based on the following formula:

Any increase made under this Section 4.04(b) will be made successively whenever any such rights, options or warrants are issued and shall become effective immediately after the Open of Business on the record date for such issuance. To the extent that such rights, options or warrants are not exercised prior to their expiration or shares of Common Stock are not delivered upon the expiration of such rights, options or warrants, the Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so issued, or if such rights, options or warrants are not exercised prior to their expiration, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such record date for such issuance had not occurred.

For purposes of this Section 4.04(b), in determining whether any rights, options or warrants entitle the holders of the Common Stock to subscribe for or purchase shares of the Common Stock at a price per share less than such average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the date of announcement for such issuance, and in determining the aggregate offering price of such shares of the Common Stock, there shall be taken into account any consideration received by the Company for such rights, options or warrants 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 Directors.

(c) If the Company distributes shares of its Capital Stock, evidences of its indebtedness, other assets or property of the Company or rights, options or warrants to acquire its Capital Stock or other securities, to all or substantially all holders of the outstanding Common Stock, excluding:

(1) dividends or distributions, rights options or warrants as to which an adjustment was effected pursuant to Section 4.04(a) hereof or Section 4.04(b) hereof;

provided that if “FMV” (as defined above) is equal to or greater than “SP₀” (as defined above), then in lieu of the foregoing increase, each Holder of a Security shall receive, in respect of each $1,000 principal amount of a Security it holds, at the same time and upon the same terms as holders of the Common Stock, the amount and kind of the Company’s Capital Stock, evidences of the Company’s indebtedness, other assets or property of the Company or rights, options or warrants to acquire the Company’s Capital Stock or other securities that such Holder would have received as if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the record date for the distribution.

Any increase made under this portion of this Section 4.04(c) will become effective immediately after the Close of Business on the record date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

With respect to an adjustment pursuant to this Section 4.04(c) where there has been a payment of a dividend or other distribution on the Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary of the Company or other business unit of the Company, and such Capital Stock or similar equity interest is listed or quoted (or will be listed or quoted upon the consummation of the distribution) on a United States national securities exchange (a “Spin-Off”), the Conversion Rate will be increased based on the following formula:

The adjustment to the applicable Conversion Rate under the preceding paragraph of this Section 4.04(c) will be made immediately after the Open of Business on the day after the last Trading Day of the Valuation Period, but will be given effect as of the Open of Business on the record date for the Spin-Off. For purposes of determining the applicable Conversion Rate, in respect of any conversion during the ten Trading Days commencing on the Ex-Dividend Date for any Spin-Off, references within the portion of this Section 4.04(c) related to “Spin-Offs” to ten Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date for such Spin-Off to, and including, the relevant Conversion Date.

For purposes of the second adjustment set forth in this Section 4.04(c), (i) the Last Reported Sale Price of any Capital Stock or similar equity interest shall be calculated in a manner analogous to that used to calculate the Last Reported Sale Price of the Common Stock in the definition of “Last Reported Sale Price” set forth in Section 1.01 hereof, (ii) whether a day is a Trading Day (and whether a day is a Scheduled Trading Day and whether a Market Disruption Event has occurred) for such Capital Stock or similar equity interest shall be determined in a manner analogous to that used to determine whether a day is a Trading Day (or whether a day is a Scheduled Trading Day and whether a Market Disruption Event has occurred) for the Common Stock, and (iii) whether a day is a Trading Day to be included in a Valuation Period will be determined based on whether a day is a Trading Day for both the Common Stock and such Capital Stock or similar equity interest.

Subject to Section 4.04(f), for the purposes of this Section 4.04(c), rights, options or warrants distributed by the Company to all holders of the Common Stock entitling them to subscribe for or purchase shares of the Company’s Capital Stock (either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (a “Trigger Event”): (1) are deemed to be transferred with such shares of Common Stock; (2) are not exercisable; and (3) are also issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this Section 4.04(c), (and no adjustment to the Conversion Rate under this Section 4.04(c) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or

warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section 4.04(c). If any such right, option or warrant, distributed prior to the Issue Date is subject to events, upon the occurrence of which such rights, options 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 of such deemed distribution (in which case the original rights, options or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders). In addition, in the event of any distribution or deemed distribution of rights, options 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 Conversion Rate under this Section 4.04(c) was made, (1) in the case of any such rights, options or warrants which shall all have been redeemed or purchased without exercise by any holders thereof, upon such final redemption or purchase (x) the Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued and (y) the Conversion Rate shall then again be readjusted to give effect to such distribution, deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or purchase price received by holders of Common Stock with respect to such rights, options or warrants (assuming each such holder had retained such rights, options or warrants), made to all holders of Common Stock as of the date of such redemption or purchase, and (2) in the case of such rights, options or warrants which shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights and warrants had not been issued.

For purposes of Section 4.04(a) hereof, Section 4.04(b) hereof and this Section 4.04(c), if any dividend or distribution to which this Section 4.04(c) applies includes one or both of:

(1) a dividend or distribution of shares of Common Stock to which Section 4.04(a) hereof also applies (the “Clause A Distribution”); or

(2) a dividend or distribution of rights, options or warrants to which Section 4.04(b) hereof also applies (the “Clause B Distribution”),

then (i) such dividend or distribution, other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section 4.04(c) applies (the “Clause C Distribution”) and any Conversion Rate adjustment required to be made under this Section 4.04(c) with respect to such Clause C Distribution shall be made, (ii) the Clause B Distribution, if any, shall be deemed to immediately follow the Clause C Distribution and any Conversion Rate adjustment required by Section 4.04(b) hereof with respect thereto shall then be made, except that, if determined by the Company, (A) the “record date” of the Clause B Distribution and the Clause A Distribution, if any, shall be deemed to be the record date of the Clause C Distribution and (B) any shares of Common Stock included in the Clause A Distribution or the Clause B Distribution shall not be deemed to be “outstanding immediately prior to the Open of Business on such record date” within the meaning of Section 4.04(b) hereof, and (iii) the Clause A Distribution, if any, shall be deemed to immediately follow the Clause C Distribution or the Clause B Distribution, as the case may be, except that, if determined by the Company, (A) the “record date” of the Clause A Distribution and the Clause B Distribution, if any, shall be deemed to be the record date of the Clause C Distribution, and (B) any shares of Common Stock included in the Clause A distribution shall not be deemed to be “outstanding immediately prior to the Open of Business on such record date or such effective date” within the meaning of Section 4.04(a) hereof.

(d) If any cash dividend or distribution is made to all or substantially all holders of the outstanding Common Stock to the extent that the aggregate of all such cash dividends or distributions paid in any quarter exceeds the dividends threshold amount (the “DTA”) for such quarter, the Conversion Rate shall be adjusted based on the following formula:

The DTA is subject to adjustment on an inversely proportional basis whenever the Conversion Rate is adjusted, other than adjustments made pursuant to this Section 4.04(d).

If “C” (as defined above) is equal to or greater than “SP₀” (as defined above), in lieu of the foregoing increase, each Holder shall receive, for each $1,000 principal amount of Securities it holds, at the same time and upon the same terms as holders of shares of the outstanding Common Stock, the amount of cash that such Holder would have received if such Holder had owned a number of shares of Common Stock equal to the Conversion Rate on the record date for such cash dividend or distribution. Such increase shall become effective immediately after the Close of Business on the record date for such dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

(e) If the Company or any of its Subsidiaries make a payment in respect of a tender offer or exchange offer for the Common Stock, to the extent that the cash and value of any other consideration included in the payment per share of the 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 (the “Offer Expiration Date”), the Conversion Rate shall be increased based on the following formula:

The adjustment to the applicable Conversion Rate under the preceding paragraph of this Section 4.04(e) will be given effect at the Open of Business on the Trading Day next succeeding the Offer Expiration Date. For purposes of determining the applicable Conversion Rate, in respect of any conversion during the ten Trading Days commencing on the Trading Day next succeeding the Offer Expiration Date, references within this Section 4.04(e) to ten Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the Offer Expiration Date to, and including, the relevant Conversion Date.

(f) Poison Pill. Whenever a Holder converts a Security, to the extent that the Company has a rights plan in effect, the Holder converting such Security will receive, in addition to any shares of Common Stock otherwise received in connection with such conversion, the rights under the rights plan unless, prior to conversion the rights have expired, terminated or been redeemed or unless the rights have separated from the Common Stock, in which case, and only in such case, the Conversion Rate will be adjusted at the time of separation (and not at the time of the issuance of the rights) as if the Company distributed to all holders of the Common Stock, shares of Capital Stock, evidences of indebtedness, assets, property, rights, options or warrants as described in Section 4.04(c) hereof, subject to readjustment in the event of the expiration, termination or redemption of such rights.

(g) Limitation on Adjustments. Except as stated in this Section 4.04, the Company will not adjust the Conversion Rate for the issuance of shares of Common Stock or any securities convertible into or exchangeable for shares of Common Stock or the right to purchase shares of the Common Stock or such convertible or exchangeable securities. If, however, the application of the formulas in Sections 4.04(a) through (e) hereof would result in a decrease in the Conversion Rate, then, except to the extent of any readjustment to the Conversion Rate, no adjustment to the Conversion Rate will be made (other than as a result of a reverse share split, share combination or readjustment).

In addition, notwithstanding anything to the contrary herein, the Conversion Rate will not be adjusted:

(1) on account of stock repurchases that are not tender offers referred to in Section 4.04(e) hereof, including structured or derivative transactions, or transactions pursuant to a stock repurchase program approved by the Board of Directors or otherwise;

(2) upon the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common Stock under any plan;

(3) upon the issuance of any shares of Common Stock or options or rights to purchase those shares pursuant to any present or future employee, director or consultant benefit plan, program or agreement (including issuances to the personnel of the Company’s external manager pursuant to any such plan, program or agreement) of or assumed by the Company or any of its Subsidiaries;

(4) upon the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security not described in the preceding clause (3) and outstanding as of the date the Securities were first issued;

(7) for an event otherwise requiring an adjustment under the Indenture if such event is not consummated.

(h) For purposes of this Section 4.04, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company, but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock.

(i) Withholding on Adjustments. If, in connection with any adjustment to the Conversion Rate as set forth in this Section 4.04 a Holder shall be deemed for U.S. federal tax purposes to have received a distribution, the Company may set off any withholding tax it reasonably believes it is required to collect with respect to any such deemed distribution

against cash payments of interest in accordance with the provisions of Section 2.04 hereof or from cash and Common Stock, if any, otherwise deliverable to a Holder upon a conversion of Securities in accordance with the provisions of Section 4.03 hereof, a repurchase of a Security in accordance with the provisions of Article 3 hereof or a redemption of a Security in accordance with the provisions of Article 11 hereof.

(a) Adjustments of Prices. Whenever any provision of the Indenture requires the Company to calculate the Last Reported Sale Prices or any function thereof over a span of multiple days, the Company will make appropriate adjustments to each to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Effective Date, Record Date or Offer Expiration Date of the event occurs, at any time during the period when such Last Reported Sale Prices or function thereof is to be calculated.

(b) Voluntary Adjustments. To the extent permitted by applicable law and the rules of the New York Stock Exchange or any other securities exchange or market on which the Common Stock is then listed, the Company is permitted to increase the Conversion Rate of the Securities by any amount for a period of at least 20 Business Days if the Board of Directors determines that such increase would be in the Company’s best interest. The Company may also (but is not required to) increase the Conversion Rate to avoid or diminish income tax to holders of Common Stock or rights to purchase shares of Common Stock in connection with a dividend or distribution of shares (or rights to acquire shares) or similar event.

Section 4.06 Adjustment to Conversion Rate Upon Conversion in Connection with a Make-Whole Fundamental Change.

(a) Increase in the Conversion Rate. If a Make-Whole Fundamental Change occurs and a Holder elects to convert its Securities in connection with such Make-Whole Fundamental Change, the Company shall, under certain circumstances, increase the Conversion Rate for the Securities so surrendered for conversion by a number of additional shares of Common Stock (the “Additional Shares”), as described in this Section 4.06. A conversion of Securities shall be deemed for these purposes to be “in connection with” a Make-Whole Fundamental Change if the relevant Conversion Notice is received by the Conversion Agent during the period from, and including, the Effective Date of the Make-Whole Fundamental Change up to, and including, the Close of Business on the Business Day immediately prior to the related Fundamental Change Purchase Date or, if such Make-Whole Fundamental Change is not a Fundamental Change, the 35th Business Day immediately following the Effective Date for such Make-Whole Fundamental Change.

(b) Determining the Number of Additional Shares. The number of Additional Shares, if any, by which the Conversion Rate will be increased for a Holder that converts its Securities in connection with a Make-Whole Fundamental Change shall be determined by reference to the table attached as Schedule A hereto, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (the “Effective Date”) and the price (the “Stock Price”) paid (or deemed paid) per share of the Common Stock in the Make-Whole Fundamental Change. If the holders of the Common Stock receive only cash in a Make-Whole Fundamental Change described in clause (2) of the definition of Fundamental Change, the Stock Price shall be the cash amount paid per share. Otherwise, the Stock Price shall be the average of the Last Reported Sale Prices of the Common Stock over the ten consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change.

(c) Interpolation and Limits. The exact Stock Prices and Effective Dates may not be set forth in the table in Schedule A, in which case:

(1) If the Stock Price is between two Stock Prices 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 higher and lower Stock Prices and the earlier and later Effective Dates, as applicable, based on a 365-day year.

(2) If the Stock Price is greater than $40.00 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table in Schedule A pursuant to Section 4.06(d)(4) hereof), the Conversion Rate shall not be increased.

(3) If the Stock Price is less than $22.70 per share (subject to adjustments in the same manner as the Stock Prices set forth in the column headings of the table in Schedule A pursuant to Section 4.06(d)(4) hereof), the Conversion Rate shall not be increased.

Notwithstanding the foregoing, in no event will the Conversion Rate be increased on account of a Make-Whole Fundamental Change to exceed 45.0528 shares of Common Stock per $1,000 principal amount of Securities, subject to adjustments in the same manner as the Conversion Rate is required to be adjusted as set forth in Section 4.04 hereof.

(4) The Stock Prices set forth in the column headings of the table in Schedule A hereto shall be adjusted as of any date on which the Conversion Rate of the Securities is otherwise required to be adjusted. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to such adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares set forth in such table shall be adjusted in the same manner and at the same time as the Conversion Rate is required to be adjusted as set forth in Section 4.04.

(d) Notices. The Company shall notify the Trustee and the Holders of the Effective Date of any Make Whole Fundamental Change announcing such Effective Date no later than five Business Days after such Effective Date. Such notice shall be sent by first class mail or, in the case of any Global Securities, in accordance with the procedures of the Depository for providing notices. Simultaneously with providing such notice, the Company shall publish this information in a newspaper of general circulation in The City of New York or publish the information on the Company’s website or through such other public medium as the Company may use at that time.

Section 4.07 Effect of Recapitalization, Reclassification, Consolidation, Merger or Sale.

(1) any recapitalization, 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 for which an adjustment was made pursuant to Section 4.04(a) hereof);

(3) any sale, lease or other transfer to a third party of the consolidated assets of the Company and its Subsidiaries substantially as an entirety; or

and, in each case, as a result of which the outstanding Common Stock would be converted into, or exchanged for, stock, other securities, other property or assets (including cash or any combination thereof) (any such event, a “Merger Event,” any such stock, other securities, other property or assets, “Reference Property,” and the amount of kind of Reference Property that a holder of one share of Common Stock (i) is entitled to receive in the applicable Merger Event or (ii) if as a result of the applicable Merger Event, each share of Common Stock is converted into the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), the per-share of Common Stock weighted average of the types and amounts of Reference Property received by the holders of Common Stock that affirmatively make such an election, a “Unit of Reference Property”) then, at the effective time of such Merger Event, the right to convert each $1,000 principal amount of Securities into a number of shares of the Common Stock equal to the applicable Conversion Rate will, without the consent of the Holders, be changed into a right to convert each $1,000 principal amount of Securities into a number of Units of Reference Property equal to the applicable Conversion Rate and, prior to or at the effective time of such Merger Event, the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the TIA as in force at the date of execution of such supplemental indenture) providing for such change in the right to convert each $1,000 principal amount of Securities. With respect to any such Reference Property, the Last Reported Sale Price will, to the extent reasonably possible, be calculated based on the value of a Unit of Reference Property and the definitions of Trading Day and Market Disruption Event shall be determined by reference to the components of a Unit of Reference Property.

If the Merger Event causes the outstanding Common Stock to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election) as contemplated by the preceding paragraph such that a Unit of Reference Property is comprised of the per-share of Common Stock weighted average of the types and amounts of consideration received by the holders of the Common Stock in the Merger Event that affirmatively make such an election, the Company shall notify Holders of the weighted average as soon as practicable after such determination is made.

The Company shall not become a party to any Merger Event unless its terms are consistent with this Section 4.07. Such supplemental indenture described in the second immediately preceding paragraph shall provide for adjustments which shall be as nearly equivalent to the adjustments provided for in this Article 4 in the judgment of the Board of Directors or the board of directors of the successor Person. If, in the case of any such Merger Event, the Reference Property receivable thereupon by a holder of Common Stock includes

shares of stock, securities or other property or assets (including cash or any combination thereof) of a Person other than the successor or purchasing Person, as the case may be, in such Merger Event, then such supplemental indenture shall also be executed by such other Person and shall contain such additional provisions to protect the interests of the Holders of the Securities as the Board of Directors shall reasonably consider necessary.

(b) Notice of Supplemental Indentures. The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Holder, at the address of such Holder as it appears on the register of the Securities maintained by the Registrar, within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. The above provisions of this Section 4.07 shall similarly apply to successive Merger Events and the provisions of this Section 4.07 and Article IX of the Base Indenture (as modified by Article 8 of this Supplemental Indenture) shall apply to any such successive Merger Events.

(a) Reservation of Shares. To the extent necessary to satisfy its obligations under the Indenture, prior to issuing any shares of Common Stock, the Company will reserve out of its authorized but unissued shares of Common Stock a sufficient number of shares of Common Stock to permit the conversion of the Securities.

(b) Certain other Covenants. The Company covenants that all shares of Common Stock that may be issued upon conversion of Securities shall be newly issued shares or treasury shares, shall be duly authorized, validly issued, fully paid and non-assessable and shall be free from preemptive rights and free from any tax, lien or charge (other than those created by the Holder or due to a change in registered owner).

(c) Stock Transfer Agent. American Stock Transfer & Trust Company is, as of the date of the this Supplemental Indenture, the Stock Transfer Agent for the Common Stock and the Company shall notify the Trustee if the Stock Transfer Agent for the Common Stock is changed. The Company and the Trustee (as Conversion Agent) agree to cooperate with the Stock Transfer Agent for the Common Stock in connection with any conversions of the Securities.

The Company shall list or cause to have quoted any shares of Common Stock to be issued upon conversion of Securities on each national securities exchange or over-the-counter or other domestic market on which the Common Stock is then listed or quoted.

Section 4.09 Responsibility of Trustee. The Trustee and any Conversion Agent shall not at any time be under any duty or responsibility to any Holder of Securities to determine or calculate the Conversion Rate (or any adjustments thereto), to determine whether any facts exist which may require any adjustment of the Conversion Rate, or to confirm the accuracy of any such adjustment when made or the appropriateness of the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other Conversion 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 other securities or property that may at any time be issued or delivered upon the conversion of any Securities; and the Trustee and the Conversion Agent make no representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property or cash upon the surrender of any Securities for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this

Article 4. The rights, privileges, protections, immunities and benefits given to the Trustee, including without limitation its right to be compensated, reimbursed, and indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, including its capacity as Conversion Agent.

(a) Notice to Holders Prior to Certain Actions. The Company shall deliver notices of the events specified below at the times specified below and containing the information specified below unless, in each case, (i) pursuant to the Indenture, the Company is already required to deliver notice of such event containing at least the information specified below at an earlier time or, (ii) the Company, at the time it is required to deliver a notice, does not have knowledge of all of the information required to be included in such notice, in which case, the Company shall (A) deliver notice at such time containing only the information that it has knowledge of at such time (if it has knowledge of any such information at such time), and (B) promptly upon obtaining knowledge of any such information not already included in a notice delivered by the Company, deliver notice to each Holder containing such information. In each case, the failure by the Company to give such notice, or any defect therein, shall not affect the legality or validity of such event. Any notices sent to Holders shall also be sent to the Trustee.

(b) Issuances, Distributions, and Dividends and Distributions. If the Company (A) announces any issuance of any rights, options or warrants that would require an adjustment in the Conversion Rate pursuant to Section 4.04(b) hereof; (B) authorizes any distribution that would require an adjustment in the Conversion Rate pursuant to Section 4.04(c) hereof (including any separation of rights from the Common Stock described in Section 4.04(g) hereof); or (C) announces any dividend or distribution that would require an adjustment in the Conversion Rate pursuant to Section 4.04(d) hereof, then the Company shall deliver to the Holders, as promptly as possible, but in any event at least 15 calendar days prior to the applicable record date, notice describing such issuance, distribution, dividend or distribution, as the case may be, and stating the expected Ex-Dividend Date and record date for such issuance, distribution, dividend or distribution, as the case may be. In addition, the Company shall deliver to the Holders notice if the consideration included in such issuance, distribution, dividend or distribution, or the Ex-Dividend Date or record date of such issuance, distribution, dividend or distribution, as the case may be, changes.

(c) Voluntary Increases. If the Company increases the Conversion Rate pursuant to Section 4.05(b), the Company shall deliver notice to the Holders at least 15 calendar days prior to the date on which such increase will become effective, which notice shall state the date on which such increase will become effective and the amount by which the Conversion Rate will be increased.

(d) Dissolutions, Liquidations and Winding-Ups. If there is a voluntary or involuntary dissolution, liquidation or winding-up of the Company, the Company shall deliver notice to the Holders at promptly as possible, but in any event at least 15 calendar days prior to the earlier of (i) the date on which such dissolution, liquidation or winding-up, as the case may be, is expected to become effective or occur, and (ii) the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such dissolution, liquidation or winding-up, as the case may be, which notice shall state the expected effective date and record date for such event, as applicable, and the amount and kind of property that a holder of

one share of the Common Stock is expected to be entitled, or may elect, to receive in such event. The Company shall deliver an additional notice to Holders, as promptly as practicable, whenever the expected effective date or record date, as applicable, or the amount and kind of property that a holder of one share of the Common Stock is expect to be entitled to receive in such event, changes.

(e) Notices After Certain Actions and Events. Whenever an adjustment to the Conversion Rate becomes effective pursuant to Sections 4.04, 4.05 or 4.06 hereof, the Company will (i) file with the Trustee an Officers’ Certificate stating that such adjustment has become effective, the Conversion Rate, and the manner in which the adjustment was computed and (ii) deliver notice to the Holders stating that such adjustment has become effective and the Conversion Rate or conversion privilege as adjusted. Failure to give any such notice, or any defect therein, shall not affect the validity of any such adjustment.

Section 5.01 Payment of Principal, Interest, Fundamental Change Purchase Price, REIT Redemption Price and Optional Redemption Price. This Section 5.01 shall replace Section 4.01 of the Base Indenture in its entirety.

The Company covenants and agrees that it will cause to be paid the principal of (including any of the Fundamental Change Purchase Price, the REIT Redemption Price or the Optional Redemption Price, if applicable), and accrued and unpaid interest, if any, on each of the Securities at the places, at the respective times and in the manner provided herein and in the Securities.

The Company will maintain an office of the Paying Agent, an office of the Registrar and an office or agency where Securities may be surrendered for conversion (“Conversion Agent”) and where notices and demands to or upon the Company in respect of the Securities and the Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office or the office or agency of the Trustee.

The Company may also from time to time designate coregistrars one or more other offices or agencies where the Securities may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. The terms “Paying Agent” and “Conversion Agent” include any such additional or other offices or agencies, as applicable.

The Company hereby initially designates the Trustee as the Paying Agent, Registrar, Custodian, Conversion Agent and the Corporate Trust Office, which shall be in the continental United States, shall be considered as one such office or agency of the Company for each of the aforesaid purposes.

With respect to any Global Security, the Corporate Trust Office of the Trustee or any Paying Agent shall be the Place of Payment where such Global Security may be presented or surrendered for payment or conversion or for registration of transfer or exchange, or where successor Securities may be delivered in exchange therefor; provided, however, that any such payment, conversion, presentation, surrender or delivery effected pursuant to the Applicable Procedures of the Depository for such Global Security shall be deemed to have been effected at the Place of Payment for such Global Security in accordance with the provisions of the Indenture.

Section 5.03 Appointments to Fill Vacancies in Trustee’s Office. The Company, whenever necessary to avoid or fill a vacancy in the office of Trustee, will appoint, in the manner provided in Section 7.08 of the Base Indenture, a Trustee, so that there shall at all times be a Trustee hereunder.

Section 5.04 Provisions as to Paying Agent. (a) If the Company shall appoint a Paying Agent other than the Trustee, the Company shall cause such Paying Agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section 5.04:

(1) that it will hold all sums held by it as such agent for the payment of the principal of, accrued and unpaid interest, if any, on, and the Fundamental Change Purchase Price, REIT Redemption Price or Optional Redemption Price for, the Securities in trust for the benefit of the holders of the Securities;

(2) that it will give the Trustee prompt notice of any failure by the Company to make any payment of the principal of, accrued and unpaid interest, if any, on, or the Fundamental Change Purchase Price, REIT Redemption Price or Optional Redemption Price for, the Securities when the same shall be due and payable; and

(3) that at any time during the continuance of an Event of Default, upon request of the Trustee, it will forthwith pay to the Trustee all sums so held in trust.

The Company shall, on or before each due date of the principal of, accrued and unpaid interest, if any, on, and the Fundamental Change Purchase Price, the REIT Redemption Price or the Optional Redemption Price for, the Securities, deposit with the Paying Agent a sum sufficient to pay such principal, accrued and unpaid interest, or the Fundamental Change Purchase Price, the REIT Redemption Price or the Optional Redemption Price, as the case may be, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of any failure to take such action, provided that, if such deposit is made on the due date, such deposit must be received by the Paying Agent by 10:00 a.m., New York City time, on such date.

(b) If the Company shall act as its own Paying Agent, it will, on or before each due date of the principal of, accrued and unpaid interest, if any, on, or Fundamental Change Purchase Price, REIT Redemption Price or Optional Redemption Price for, the Securities, set aside, segregate and hold in trust for the benefit of the holders of the Securities a sum sufficient to pay such principal, accrued and unpaid interest, if any, on or Fundamental Change Purchase Price, REIT Redemption Price or Optional Redemption Price, as the case may be, so becoming due and will promptly notify the Trustee in writing of any failure to take such action and of any failure by the Company to make any payment of the principal of, accrued and unpaid interest on, or Fundamental Change Purchase Price, REIT Redemption Price or Optional Redemption Price for, the Securities when the same shall become due and payable.

(c) Anything in this Section 5.04 to the contrary notwithstanding, but subject to Article 7, the Company may, at anytime, for the purpose of obtaining a satisfaction and discharge of the Indenture, or for any other reason, pay or cause to be paid to the Trustee all sums held in trust by the Company or any Paying Agent hereunder as required by this Section 5.04, such sums to be held by the Trustee upon the trusts herein contained and upon such payment by the Company or any Paying Agent to the Trustee, the Company or such Paying Agent shall be released from all further liability with respect to such sums.

Section 5.05 Reports. This Section 5.05 will replace Section 4.02 of the Base Indenture in its entirety.

The Company will file with the Trustee, within 15 days after it is required to file the same with the SEC, copies of the quarterly and annual reports and of the information, documents and other reports, if any, that it is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act, and to otherwise comply with Section 314(a) of the TIA. Any such report, information or document that the Company files with the SEC through the EDGAR system (or any successor thereto) will be deemed to be delivered to the Trustee for the purposes of this Section 5.05 at the time of such filing through the EDGAR system (or such successor thereto).

Delivery of any such reports, information and documents to the Trustee shall be for informational purposes only, and the Trustee’s receipt of such reports, information and documents shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

Section 5.06 Statements as to Defaults. The Company shall deliver to the Trustee, as soon as possible, and in any event within thirty days after the Company becomes aware of the occurrence of any Default or Event of Default, an Officers’ Certificate setting forth the details of such Default or Event of Default, its status and the action that the Company proposes to take with respect thereto. Such Officers’ Certificate shall also comply with any additional requirements set forth in Section 12.05 of the Base Indenture.

Section 5.07 Supplementary Interest Notice. If Supplementary Interest is payable by the Company pursuant to Section 6.04 hereof, the Company shall deliver to the Trustee an Officers’ Certificate to that effect stating (a) the amount of such Supplementary Interest (in aggregate and per $1,000 principal amount of Securities) and (b) the date on which such interest is payable. Unless and until a Responsible Officer of the Trustee receives at the Corporate Trust Office such a certificate, the Trustee may assume without inquiry that no such Supplementary Interest is payable. If the Company has paid Supplementary Interest directly to the Persons entitled to them, the Company shall deliver to the Trustee an Officers’ Certificate setting forth the particulars of such payment.

Section 5.08 Covenant to Take Certain Actions. Before taking any action which would cause an adjustment to the Conversion Rate such that the Conversion Price per share of Common Stock issuable upon conversion of the Securities would be less than the par value of the Common Stock, the Company shall take all corporate actions that may, in the opinion of its counsel, be necessary so it may validly and legally issue shares of Common Stock at such adjusted Conversion Rate.

(a) The Holders shall not have the benefit of Article VI of the Base Indenture and, with respect to the Securities, this Article 6 supersedes Article VI of the Base Indenture in its entirety.

(b) The references to Section 6.05 in Section 7.01(c)(i) and (g) of the Base Indenture are, with respect to the Securities, hereby deemed replaced by references to Section 6.06 of this Supplemental Indenture.

(c) The references to Section 6.01(d) and (e) in the third paragraph of Section 7.07 of the Base Indenture are, with respect to the Securities, hereby deemed replaced by references to Section 6.02(h) and (i) of this Supplemental Indenture.

(d) The reference to Section 6.04 in Section 9.02 of the Base Indenture is, with respect to the Securities, hereby deemed replaced by reference to Section 6.05 of this Supplemental Indenture.

(e) The reference to Section 6.08 in Section 9.02 of the Base Indenture is, with respect to the Securities, hereby deemed replaced by a reference to Section 6.08 of this Supplemental Indenture.

Section 6.02 Events of Default. Each of the following events (and only the following events) shall be an “Event of Default” wherever used with respect to the Securities:

(a) default in any payment of interest on any Security when due and payable, and the default continues for a period of 30 days;

(b) default in the payment of the principal of any Security (including the Fundamental Change Purchase Price, REIT Redemption Price or Optional Redemption Price) when due and payable on the Maturity Date, upon required repurchase, upon declaration of acceleration or otherwise;

(c) failure by the Company to comply with its obligations under Article 4 hereof to convert the Securities into shares of Common Stock determined in accordance with Article 4 hereof upon exercise of a Holder’s conversion right and that failure continues for three Business Days;

(d) failure by the Company to comply with its obligations under Article 9 hereof;

(e) failure by the Company to issue a notice in accordance with the provisions of Section 3.02(b) hereof when due;

(f) failure by the Company for 60 days after written notice from the Trustee or the Holders of at least 25% in principal amount of the Securities then Outstanding (a copy of which notice, if given by Holders, must also be given to the Trustee) has been received by the Company to comply with any of its other agreements contained in the Securities or the Indenture (other than a covenant or warranty a default in whose performance or whose breach is elsewhere in this Section 6.02 specifically provided for or that is not applicable to the Securities), which notice shall state that it is a “Notice of Default” hereunder;

(g) failure by the Company to pay beyond any applicable grace period, or the acceleration of, indebtedness (other than Non-Recourse Indebtedness) of the Company or any of the Company’s Subsidiaries in an aggregate principal amount with respect to which the default has occurred is greater than $10,000,000 (or its foreign currency equivalent at the time);

(h) the Company or any Significant Subsidiary of the Company shall commence a voluntary case or other proceeding seeking the liquidation, reorganization or other relief with respect to the Company or such Significant Subsidiary or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of the Company or such Significant Subsidiary of the Company or any substantial part of the Company’s or such Significant Subsidiary of the Company’s property, or shall consent to any such relief or to the appointment of or taking possession by any such official in an involuntary case or other proceeding commenced against it, or shall make a general assignment for the benefit of creditors, or shall fail generally to pay its debts as they become due; or

(i) an involuntary case or other proceeding shall be commenced against the Company or any Significant Subsidiary of the Company seeking liquidation, reorganization or other relief with respect to the Company or such Significant Subsidiary of the Company or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of the Company or such Significant Subsidiary of the Company or any substantial part of its property, and such involuntary case or other proceeding shall remain undismissed and unstayed for a period of thirty consecutive days.

Section 6.03 Acceleration; Rescission and Annulment. If one or more Events of Default shall have occurred and be continuing (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body), then, and in each and every such case (other than an Event of Default specified in Section 6.02(h) or Section 6.02(i)), unless the principal of all of the Securities shall have already become due and payable, either the Trustee or the holders of at least 25% in aggregate principal amount of the Securities then Outstanding, by notice in writing to the Company (and to the Trustee if given by the Holders), may declare 100% of the principal of, and accrued and unpaid interest, if any, on all the Securities to be due and payable immediately. If an Event of Default specified in Section 6.02(h) or Section 6.02(i) occurs and is continuing, the principal of, and accrued and unpaid interest, if any, on all Securities shall be immediately due and payable.

(a) Notwithstanding any provisions of the Indenture to the contrary, if the Company so elects, the sole remedy for an Event of Default relating to (i) the Company’s failure to file with the Trustee pursuant to Section 314(a)(1) of the TIA any documents or

reports that it is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act, or (ii) the Company’s failure to comply with Section 5.06 hereof (a “Reporting Event of Default”), will consist exclusively of the right to receive additional interest on the Securities (the “Supplementary Interest”) at a rate per year equal to 0.50% per annum of the Outstanding principal amount of the Securities for each day during such 180-day period as long as such Event of Default is continuing (and neither waived nor cured). If the Company so elects, such Supplementary Interest will be payable in the same manner and on the same dates as the stated interest payable on the Securities. On the 181st day after such Event of Default (if the Reporting Event of Default is not cured or waived prior to such 181st day), the Securities will be subject to acceleration pursuant to Section 6.03. The provisions of this Section 6.04 will not affect the rights of Holders of Securities in the event of the occurrence of any Event of Default that is not a Reporting Event of Default. In the event the Company does not elect to pay the Supplementary Interest following an Event of Default in accordance with this Section 6.04 or the Company elects to make such payment but does not pay the Supplementary Interest when due, the Securities will be immediately subject to acceleration as provided in Section 6.03.

(b) In order to elect to pay the Supplementary Interest as the sole remedy during the first 180 days after the occurrence of a Reporting Event of Default, the Company must notify all Holders of Securities, the Trustee and the Paying Agent of such election prior to the beginning of such 180-day period. Upon the Company’s failure to timely give such notice, the Securities will be immediately subject to acceleration as provided in Section 6.03.

Section 6.05 Waiver of Past Defaults. The Holders of a majority in aggregate principal amount of the Securities then Outstanding, by written notice to the Company and to the Trustee, may waive (including by way of consents obtained in connection with a repurchase of, or tender or exchange offer for, the Securities) all past Defaults or Events of Default with respect to the Securities (other than a Default or an Event of Default resulting from nonpayment of principal or interest, a failure to deliver consideration due upon conversion or any other provisions that requires the consent of each affected Holder to amend) and rescind any such acceleration with respect to the Securities and its consequences if (i) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (ii) all existing Events of Default, other than the nonpayment of the principal of, and interest on, the Securities that have become due solely by such declaration of acceleration have been cured or waived.

Section 6.06 Control by Majority. At anytime, the Holders of a majority of the aggregate principal amount of the then Outstanding Securities may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or for exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or the Indenture or, subject to the Trustee’s duties under Article VII of the Base Indenture and the TIA, that the Trustee determines to be unduly prejudicial (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not any such directions are unduly prejudicial) to the rights of a Holder or to the Trustee, or that would potentially involve the Trustee in personal liability unless the Trustee is offered indemnity and/or security satisfactory to it against any loss, liability or expense to the Trustee that may result from the Trustee’s instituting such proceeding as the Trustee. Prior to taking any action hereunder, the Trustee will be entitled to indemnification and/or security satisfactory to it against all losses and expenses caused by taking or not taking such action.

Section 6.07 Limitation on Suits. Subject to Section 6.08 hereof, no Holder may pursue a remedy with respect to the Indenture or the Securities unless:

(a) such Holder has previously delivered to the Trustee written notice that an Event of Default is continuing;

(b) the Holders of at least 25% of the aggregate principal amount of the then Outstanding Securities request that the Trustee pursue a remedy with respect to such Event of Default;

(c) such Holder or Holders have offered and, if requested, provided to the Trustee indemnity and/or security satisfactory to the Trustee against any loss, liability or other expense of compliance with such written request;

(d) the Trustee has not complied with such request within 60 days after receipt of such written request and offer of security or indemnity; and

(e) during such 60-day period, the Holders of a majority of the aggregate principal amount of the then Outstanding Securities did not deliver to the Trustee a direction inconsistent with such request.

Section 6.08 Rights of Holders to Receive Payment and to Convert. Notwithstanding anything to the contrary elsewhere in the Indenture, the right of any Holder to receive payment of the principal of, interest on, Fundamental Change Purchase Price, REIT Redemption Price or Optional Redemption Price for, its Securities, on or after the respective due date, and to convert its Securities and receive payment or delivery of the consideration due with respect to such Securities in accordance with Article 4 hereof, or to bring suit for the enforcement of any such payment or conversion rights, will not be impaired or affected without the consent of such Holder and will not be subject to the requirements of Section 6.07 hereof.

Section 6.09 Collection of Indebtedness; Suit for Enforcement by Trustee. If an Event of Default specified in Section 6.02(a), 6.02(b) or 6.02(c) hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of principal of, interest on, Fundamental Change Purchase Price, REIT Redemption Price or Optional Redemption Price for, and the consideration due upon the conversion of, the Securities, as the case may be, and such further amount as is sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, as well as any other amounts that may be due under Section 7.07 of the Base Indenture.

Section 6.10 Trustee May Enforce Claims Without Possession of Securities. All rights of action and claims under the Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders in respect of which such judgment has been recovered.

Section 6.11 Trustee May File Proofs of Claim. The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable to have the claims of the Trustee and the Holders allowed in any judicial proceedings relative to the Company, its creditors or its property and, unless prohibited by law or applicable regulations, will be entitled to collect, receive and distribute any money or other property payable or deliverable on any such claims, and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and, in the event that the Trustee consents to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under the Base Indenture (including Section 7.07 of the Base Indenture) and this Supplemental Indenture. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 of the Base Indenture out of the estate in any such proceeding, will be denied for any reason, payment of the same will be secured by a lien on, and is paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding, whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained will be deemed to authorize the Trustee to authorize or consent to, or to accept or to adopt on behalf of any Holder, any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.12 Restoration of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under the Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

Section 6.13 Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in Section 2.09 of the Base Indenture, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 6.14 Delay or Omission Not a Waiver. No delay or omission of the Trustee or of any Holder to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article 6 or by law to the Trustee or to the Holders may be exercised from time to time and as often as may be deemed expedient by the Trustee (subject to the limitations contained in the Indenture) or by the Holders, as the case may be.

Section 6.15 Priorities. If the Trustee collects any money pursuant to this Article 6, it will pay out the money in the following order:

FIRST: to the Trustee, its agents and attorneys for amounts due under Section 7.07 of the Base Indenture and this Supplemental Indenture, including payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection;

SECOND: to the Holders, for any amounts due and unpaid on the principal of, accrued and unpaid interest on, Fundamental Change Purchase Price, REIT Redemption Price or Optional Redemption Price for, and any cash due upon conversion of, any Security, without preference or priority of any kind, according to such amounts due and payable on all of the Securities; and

THIRD: the balance, if any, to the Company or to such other party as a court of competent jurisdiction directs.

The Trustee may fix a record date and payment date for any payment to the Holders pursuant to this Section 6.15. If the Trustee so fixes a record date and a payment date, at least 15 days prior to such record date, the Company will deliver to each Holder and the Trustee a written notice, which notice will state such record date, such payment date and the amount of such payment.

Section 6.16 Undertaking for Costs. All parties to the Indenture agree, and each Holder, by such Holder’s acceptance of a Security, shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under the Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided, however, that the provisions of this Section 6.16 shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in aggregate principal amount of the Securities then Outstanding, or to any suit instituted by any Holder for the enforcement of the payment of the principal of, accrued and unpaid interest, if any, on, or Fundamental Change Purchase Price, REIT Redemption Price or Optional Redemption Price for, any Security on or after the due date expressed or provided for in the Indenture or to any suit for the enforcement of the right to convert any Security in accordance with the provisions of Article 4 hereof.

Section 6.17 Waiver of Stay, Extension and Usury Laws. The Company covenants that, to the extent that it may lawfully do so, it will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of the Indenture; and the Company, to the extent that it may lawfully do so, hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will instead suffer and permit the execution of every such power as though no such law has been enacted.

Section 6.18 Notices from the Trustee. Notwithstanding anything to the contrary in the Base Indenture, whenever a Default occurs and is continuing and a Responsible Officer of the Trustee has received written notice of such Default, the Trustee must deliver notice of such Default to the Holders within 90 days after the date on which such Default first occurred. Except in the case of a Default in the payment of the principal of, interest on, or Fundamental Change Purchase Price, REIT Redemption Price or Optional Redemption Price for, any Security or of a Default in the payment or delivery, as the case may be, of the consideration due upon conversion of a Security, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a trust committee of directors and/or Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interests of the Holders.

Section 7.01 Inapplicability of Provisions of Base Indenture; Satisfaction and Discharge of the Indenture. Article VIII of the Base Indenture shall not apply with respect to the Securities. The provisions set forth in this Article 7 shall, with respect to the Securities, supersede in their entirety Article VIII of the Base Indenture.

When (a) the Company shall deliver to the Registrar for cancellation all Securities theretofore authenticated (other than any Securities that have been destroyed, lost or stolen and in lieu of or in substitution for which other Securities shall have been authenticated and delivered) and not theretofore canceled, or (b) all the Securities not theretofore canceled or delivered to the Trustee for cancellation shall have become due and payable (whether on the Maturity Date, on any Fundamental Change Purchase Date, REIT Redemption Price or Optional Redemption Price, upon conversion or otherwise) and the Company shall deposit with the Trustee, in trust, or deliver to the Holders, as applicable, an amount of cash and shares of Common Stock, if any, as the case may be (solely to settle amounts due with respect to outstanding conversions), sufficient to pay all amounts due on all of such Securities (other than any Securities that shall have been mutilated, destroyed, lost or stolen and in lieu of or in substitution for which other Securities shall have been authenticated and delivered) not theretofore canceled or delivered to the Trustee for cancellation, including principal and interest due, accompanied, except in the event the Securities are due and payable solely in cash at the Maturity Date or upon an earlier Fundamental Change Purchase Date, REIT Redemption Price or Optional Redemption Price, by a verification report as to the sufficiency of the deposited amount from an independent certified accountant or other financial professional reasonably satisfactory to the Trustee, and if the Company shall also pay or cause to be paid all other sums payable hereunder by the Company, then the Indenture shall cease to be of further effect (except as to (i) rights hereunder of Holders to receive all amounts owing upon the Securities and the other rights, duties and obligations of Holders, as beneficiaries hereof with respect to the amounts, if any, so deposited with the Trustee and (ii) the rights, obligations and immunities of the Trustee hereunder), and the Trustee, on written demand of the Company accompanied by an Officers’ Certificate and an Opinion of Counsel and at the cost and expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of the Indenture; the Company, however, hereby agrees to reimburse the Trustee for any costs or expenses thereafter reasonably and properly incurred by the Trustee, including the fees and expenses of its counsel, and to compensate the Trustee for any services thereafter reasonably and properly rendered by the Trustee in connection with the Indenture or the Securities.

Section 7.02 Deposited Monies to Be Held in Trust by Trustee. Subject to Section 7.04 hereof, all monies and shares of Common Stock, if any, deposited with the Trustee pursuant to Section 7.01 hereof shall be held in trust for the sole benefit of the Holders of the Securities, and such monies and shares of Common Stock shall be applied by the Trustee to the payment, either directly or through any Paying Agent (including the Company if acting as its own Paying Agent), to the Holders of the particular Securities for the payment or settlement of which such monies or shares of Common Stock have been deposited with the Trustee, of all sums or amounts due and to become due thereon for principal and interest, if any.

Section 7.03 Paying Agent to Repay Monies Held. Upon the satisfaction and discharge of the Indenture, all monies and shares of Common Stock, if any, then held by any Paying Agent (if other than the Trustee) shall, upon written request of the Company, be repaid to it or paid to the Trustee, and thereupon such Paying Agent shall be released from all further liability with respect to such monies and shares of Common Stock.

Section 7.04 Return of Unclaimed Monies. Subject to the requirements of applicable law, any monies and shares of Common Stock deposited with or paid to the Trustee for payment of the principal of or interest, if any, on the Securities and not applied but remaining unclaimed by the Holders of the Securities for two years after the date upon which the principal of or interest, if any, on such Securities, as the case may be, shall have become due and payable, shall be repaid to the Company by the Trustee on written demand, and all liability of the Trustee shall thereupon cease with respect to such monies and shares of Common Stock; and the Holder shall thereafter look only to the Company for any payment or delivery that such Holder may be entitled to collect unless an applicable abandoned property law designates another Person.

Section 7.05 Reinstatement. If the Trustee or the Paying Agent is unable to apply any money or shares of Common Stock in accordance with Section 7.02 by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under the Indenture and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to Section 7.01 until such time as the Trustee or the Paying Agent is permitted to apply all such money and shares of Common Stock in accordance with Section 7.02; provided, however, that if the Company makes any payment of interest on, principal of or payment or delivery in respect of any Security following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money or shares of Common Stock, if any, held by the Trustee or Paying Agent.

Section 8.01 Supplemental Indentures Without Consent of Holders. Section 9.01 of the Base Indenture shall not apply with respect to the Securities, and this Section 8.01 shall replace Section 9.01 of the Base Indenture in its entirety.

Without the consent of any Holder, the Company (when authorized by a Board Resolution) and the Trustee, at any time and from time to time, may enter into one or more indentures supplemental hereto, in form satisfactory to the Trustee, for any of the following purposes:

(a) to conform the terms of the Indenture or the Securities to the description thereof in the Preliminary Prospectus Supplement, as supplemented by the issuer free writing prospectus related to the offering of the Securities filed by the Company with the SEC pursuant to Rule 433 under the Securities Act on August 15, 2017;

(b) to evidence the succession by a Successor Company and to provide for the assumption by a Successor Company of the Company’s obligations under the Indenture;

(f) to add to the Company’s covenants such further covenants, restrictions or conditions for the benefit of the Holders (or any other holders) or surrender any right or power conferred upon the Company by the Indenture;

(g) to cure any ambiguity, defect or inconsistency in the Indenture or the Securities, including to eliminate any conflict with the TIA, or to make any other change that does not adversely affect the rights of any Holder in any material respect;

(j) to comply with any requirement of the SEC in connection with the qualification of the Indenture under the TIA.

Section 8.02 Supplemental Indentures With Consent of Holders. Section 9.02 of the Base Indenture shall not apply with respect to the Securities, and this Section 8.02 shall replace Section 9.02 of the Base Indenture in its entirety.

With the consent of the Holders of not less than a majority in principal amount of the Outstanding Securities affected by such supplemental indenture, including without limitation, consents obtained in connection with a purchase of, or tender or exchange offer for, Securities and by consent of said Holders delivered to the Company and the Trustee, the Company, when authorized by a Board Resolution, and the Trustee may enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of modifying in any manner the rights of the Holders under the Indenture; provided, however, that no such supplemental indenture shall, without the consent of the Holder of each Outstanding Security affected thereby:

(a) reduce the percentage in aggregate principal amount of Securities Outstanding necessary to waive any past Default or Event of Default;

(b) reduce the rate of interest on any Security or change the time for payment of interest on any Security;

(e) make any change that impairs or adversely affects the conversion rights of any Securities;

(f) reduce the Fundamental Change Purchase Price, REIT Redemption Price or Optional Redemption Price of any Security or amend or modify in any manner adverse to the rights of the Holders of the Securities the Company’s obligation to pay the Fundamental Change Purchase Price, REIT Redemption Price or Optional Redemption Price, whether through an amendment or waiver of provisions in the covenants, definitions related thereto or otherwise;

(g) impair the right of any Holder of Securities to receive payment of principal of, and interest, if any, on, its Securities, or the right to receive the consideration due upon conversion of its Securities on or after the due dates therefore or to institute suit for the enforcement of any such payment or delivery, as the case may be, with respect to such Holder’s Securities;

(h) modify the ranking provisions of the Indenture in a manner that is adverse to the rights of the Holders of the Securities; or

(i) make any change to the provisions of this Article 8 that requires each Holder’s consent or in the waiver provisions in Section 6.05 of this Supplemental Indenture if such change is adverse to the rights of Holders of the Securities.

It shall not be necessary for the consent of Holders under this Section 8.02 to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such consent shall approve the substance thereof. The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Persons entitled to consent to any indenture supplemental hereto. If a record date is fixed, the Holders on such record date, or their duly designated proxies, and only such Persons, shall be entitled to consent to such supplemental indenture, whether or not such Holders remain Holders after such record date; provided that, unless such consent shall have become effective by virtue of the requisite percentage having been obtained prior to the date which is 90 days after such record date, any such consent previously given shall automatically and without further action by any Holder be cancelled and of no further effect.

For the avoidance of doubt, the provisions of Article IX of the Base Indenture other than Sections 9.01 and 9.02 shall remain in effect and continue to apply with respect to the Securities.

Section 8.03 Notice of Amendment or Supplement. After an amendment or supplement under this Article 8 becomes effective, the Company shall mail to the Holders a notice briefly describing such amendment or supplement. However, the failure to give such notice to all the Holders, or any defect in the notice, shall not impair or affect the validity of the amendment or supplement.

(a) The provisions in Article V of the Base Indenture shall not apply with respect to the Securities, and this Article 9 supersedes the entirety thereof.

(b) In addition, the reference to Article V in Section 4.03 of the Base Indenture is, with respect to the Securities, deemed replaced with a reference to this Article 9.

Section 9.02 Company May Consolidate, Etc. on Certain Terms. Subject to the provisions of Section 9.04, the Company shall not amalgamate or consolidate with, merge with or into or convey, transfer or lease its properties and assets substantially as an entirety to another Person, unless:

(a) the Company shall be the surviving Person or the resulting, surviving or transferee Person (the “Successor Company”), if not the Company, shall be a corporation organized and existing under the laws of the United States of America, any State thereof or the District of Columbia, and the Successor Company (if not the Company) shall expressly assume, by supplemental indenture, executed and delivered to the Trustee, in form satisfactory to the Trustee, all of the obligations of the Company under the Securities and the Indenture as applicable to the Securities; and

(f) If a Holder converts a Security a portion of which has been selected for REIT Redemption or Optional Redemption, as applicable, the converted portion will be deemed to be from the portion selected for REIT Redemption or Optional Redemption, as applicable.
