Section 2.03. Form Of Reverse Of Security. This Security is one of a duly authorized issue of Securities of the Company, designated as its Zero Coupon Convertible Senior Notes due 2023, in an aggregate principal amount of $90,000,000 (herein called the “Securities”), all issued or to be issued under and pursuant to an Indenture dated as of July 14, 2003 (herein called the “Indenture”), between the Company and The Bank of New York (herein called the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Securities.

The indebtedness evidenced by the Securities is unsecured and unsubordinated indebtedness of the Company and ranks equally with the Company’s other unsecured and unsubordinated indebtedness.

Repurchase By the Company at the Option of the Holder. At the option of the Holder and subject to the terms and conditions of the Indenture, the Company shall become obligated to repurchase the Securities at 100% of the Principal Amount (the “Optional Repurchase Price”), which Optional Repurchase Price shall be paid in cash, on July 14, 2007, July 14, 2013, and July 14, 2018.

Holders have the right to withdraw any Optional Repurchase Notice by delivering to the Paying Agent a written notice of withdrawal in accordance with the provisions of the Indenture.

If cash sufficient to pay the Optional Repurchase Price of all Securities or portions thereof to be purchased on the Optional Repurchase Date are deposited with the Paying Agent on the Business Day following the Optional Repurchase Date, the Holder thereof shall have no other rights as such (other than the right to receive the Optional Repurchase Price upon surrender of such Security).

Repurchase By the Company at the Option of the Holder Upon Change of Control. At the option of the Holder and subject to the terms and conditions of the Indenture, the Company shall become obligated to repurchase the Securities if a Change of Control occurs at any time prior to July 14, 2023 at 100% of the Principal Amount (the “Change of Control Repurchase Price”), which Change of Control Repurchase Price shall be paid in cash, shares of the Company’s Common Stock, shares of common stock of the surviving corporation or a combination of cash and shares of the applicable common stock.

Holders have the right to withdraw any Change of Control Repurchase Notice by delivering to the Paying Agent a written notice of withdrawal in accordance with the provisions of the Indenture.

If cash sufficient to pay the portion of the Change of Control Repurchase Price that is to be paid in cash of all Securities or portions thereof to be purchased on a Change of Control Repurchase Date are deposited with the Paying Agent on the Business Day following the Change of Control Repurchase Date, the Holder thereof shall have no other rights as such (other than the right to receive the Change of Control Repurchase Price upon surrender of such Security).

Redemption at the Option of the Company. The Company may choose to redeem the Securities at any time on or after July 14, 2008, in whole or in part, at a redemption price equal to 100% of the Principal Amount (the “Redemption Price”) of the Securities to be redeemed if:

(i) the Sales Price of the Common Stock, as calculated by the Company, for each of the thirty (30) consecutive Trading Days preceding the day on which the Company mails the Redemption Notice is equal to at least one hundred thirty percent (130%) of the Conversion Price; or

(ii) at such time at least ninety percent (90%) of the initial aggregate Principal Amount of all of the Securities has been converted, redeemed or repurchased.

If cash sufficient to pay the Redemption Price of all Securities or portions thereof to be redeemed on a Redemption Date are deposited with the Paying Agent, the Holder thereof shall have no other rights as such (other than the right to receive the Redemption Price upon surrender of such Security).

Conversion. Subject to and in compliance with the provisions of the Indenture, including without limitation the conditions of conversion of this Security set forth in Section 13.01 thereof, the Holder hereof has the right, at its option at any time prior to the earlier of the redemption or repurchase of the Security and the close of business on the Stated Maturity of the Security, to convert the Principal Amount hereof or any portion of such principal which is $1,000 or an integral multiple thereof, into, subject to Section 13.02 of the Indenture, that number of fully paid and non-assessable shares of Common Stock, as said shares shall be constituted at the date of conversion, obtained by dividing the Principal Amount of this Security or portion thereof to be converted by the conversion price of $44.76 (the “Conversion Price”) as adjusted from time to time as provided in this Indenture, upon surrender of this Security, together with a Conversion Notice as provided in this Indenture, to the Company at the office or agency of the Company maintained for that purpose in the Borough of Manhattan, The City of New York, or at the option of such Holder, the Corporate Trust Office, and, unless the shares issuable on conversion are to be issued in the same name as this Security, duly endorsed by, or accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the Holder or by his duly authorized attorney. No fractional shares will be issued upon any conversion, but an adjustment and payment in cash will be made, as provided in the Indenture, in respect of any fraction of a share which would otherwise be issuable upon the surrender of any Securities for conversion. Securities in respect of which a Holder is exercising its right to require repurchase on a Repurchase Date may be converted only if such Holder withdraws its election to exercise such right in accordance with the terms of the Indenture.

The Company will notify Holders of any event triggering the right to convert the Securities as specified above in accordance with the Indenture.

[INCLUDE IF SECURITY IS A GLOBAL SECURITY]—In the event of a deposit or withdrawal of an interest in this Security, including an exchange, transfer, redemption, repurchase or conversion of this Security in part only, the Trustee, as custodian of the Depositary, shall make an adjustment on its records to reflect such deposit or withdrawal in accordance with the rules and procedures of the Depositary.

[INCLUDE IF SECURITY IS A RESTRICTED SECURITY]—Subject to certain limitations in the Indenture, at any time when the Company is not subject to Section 13 or 15(d) of the United States Securities Exchange Act of 1934, as amended, upon the request of a Holder of a Restricted Security, the Company will promptly furnish or cause to be furnished Rule 144A Information (as defined below) to such

Holder of Restricted Securities, or to a prospective purchaser of any such security designated by any such Holder, to the extent required to permit compliance by any such Holder with Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”). “Rule 144A Information” shall be such information as is specified pursuant to Rule 144A(d)(4) under the Securities Act (or any successor provision thereto).

If an Event of Default shall occur and be continuing, the Principal Amount plus accrued but unpaid Liquidated Damages Amounts, if any, may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in aggregate Principal Amount of the Outstanding Securities. The Indenture also contains provisions permitting the Holders of specified percentages in aggregate Principal Amount of the Outstanding Securities, on behalf of the Holders of all the Securities, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities, the Holders of not less than 25% in aggregate Principal Amount of the Outstanding Securities shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee indemnity satisfactory to it, and the Trustee shall not have received from the Holders of a majority in Principal Amount of Outstanding Securities a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of said principal hereof on or after the respective due dates expressed herein or for the enforcement of any conversion right.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the Principal Amount, Redemption Price, Repurchase Price of, and Liquidated Damages Amounts, if any, on, this Security at the times, place and rate, and in the coin or currency, herein prescribed.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in The City of New York, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities, of authorized denominations and for the same aggregate Principal Amount, will be issued to the designated transferee or transferees.

The Securities are issuable only in registered form in denominations of $1,000 and any integral multiple of $1,000 above that amount, as provided in the Indenture and subject to certain limitations therein set forth. Securities are exchangeable for a like aggregate Principal Amount of Securities of a different authorized denomination, as requested by the Holder surrendering the same.

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

This Security shall be governed by and construed in accordance with the laws of the State of New York.

All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

of the Company by its Chief Executive Officer or its Chief Financial Officer. The signature of any of these officers on the Securities may be manual or facsimile.

Securities bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities.

At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities. The Company Order shall, in accordance with this Section 3.03, specify the amount of Securities to be authenticated, and shall further specify the amount of such Securities to be issued as a Global Security or as Physical Securities. The Trustee in accordance with such Company Order shall authenticate and deliver such Securities as in this Indenture provided and not otherwise.

Each Security shall be dated the date of its authentication.

No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder.

Section 3.04. Temporary Securities. Pending the preparation of definitive Securities, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of such Securities.

If temporary Securities are issued, the Company will cause definitive Securities to be prepared without unreasonable delay. After the preparation of definitive Securities, the temporary Securities shall be exchangeable for definitive Securities upon surrender of the temporary Securities at any office or agency of the Company designated pursuant to Section 10.02, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like Principal Amount of definitive Securities of authorized denominations. Until so exchanged the temporary Securities shall in all respects be entitled to the same benefits under this Indenture as definitive Securities.

Section 3.05. Registration; Registration Of Transfer And Exchange Restrictions On Transfer. (a) The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency designated pursuant to Section 10.02 being herein sometimes collectively referred to as the “Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities and of transfers of Securities. The Trustee is hereby appointed “Security Registrar” (the “Security Registrar”) for the purpose of registering Securities and transfers of Securities as herein provided.

Upon surrender for registration of transfer of any Security at an office or agency of the Company designated pursuant to Section 10.02 for such purpose, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of any authorized denominations and of a like aggregate Principal Amount and tenor, each such Security bearing such restrictive legends as may be required by this Indenture (including Section 2.02, 2.05 and 3.10).

At the option of the Holder and subject to the other provisions of this Section 3.05 and to Section 3.10,

Securities may be exchanged for other Securities of any authorized denominations and of a like aggregate Principal Amount and tenor, upon surrender of the Securities to be exchanged at such office or agency. Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive.

All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange.

Every Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed, by the Holder thereof or his attorney duly authorized in writing. As a condition to the registration of transfer of any Restricted Securities, the Company or the Trustee may require evidence satisfactory to them as to the compliance with the restrictions set forth in the legend on such securities.

Except as provided in the following sentence and in Section 3.10, all Securities originally issued hereunder and all Securities issued upon registration of transfer or exchange or replacement thereof shall be Restricted Securities and shall bear the legend required by Section 2.02 and 2.05, unless the Company shall have delivered to the Trustee (and the Security Registrar, if other than the Trustee) a Company Order stating that the Security is not a Restricted Security and may be issued without such legend thereon. Securities which are issued upon registration of transfer of, or in exchange for, Securities which are not Restricted Securities shall not be Restricted Securities and shall not bear such legend.

No service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 3.04 or 9.06 not involving any transfer.

The Company shall not be required to exchange or register a transfer of any Security (i) that has been surrendered for conversion, (ii) as to which a Redemption Notice has been delivered, except, where such Redemption Notice provides that such Security is to be redeemed only in part, the Company shall be required to exchange or register a transfer of the portion thereof not to be redeemed or (iii) as to which a Repurchase Notice has been delivered and not withdrawn, except, where such Repurchase Notice provides that such Security is to be purchased only in part, the Company shall be required to exchange or register a transfer of the portion thereof not to be purchased.

(b) Beneficial ownership of every Restricted Security shall be subject to the restrictions on transfer provided in the legends required to be set forth on the face of each Restricted Security pursuant to Section 2.02 and 2.05, unless such restrictions on transfer shall be terminated in accordance with this Section 3.05(b) or Section 3.10. The Holder of each Restricted Security, by such Holder’s acceptance thereof, agrees to be bound by such restrictions on transfer.

The restrictions imposed by this Section 3.05 and Sections 2.02, 2.05 and 3.10 upon the transferability of any particular Restricted Security shall cease and terminate upon delivery by the Company to the Trustee of an Officers’ Certificate stating that such Restricted Security has been sold pursuant to an effective Resale Registration Statement under the Securities Act or transferred in compliance with Rule 144 under the Securities Act (or any successor provision thereto). Any Restricted Security as to which the Company has delivered to the Trustee an Officers’ Certificate that such restrictions on transfer shall have expired in accordance with their terms or shall have terminated may, upon surrender of such Restricted Security for exchange to the Security Registrar in accordance with the provisions of this Section 3.05, be exchanged for a new Security, of like tenor and aggregate Principal Amount, which shall not bear the restrictive legends required by Section 2.02 and 2.05. The Company shall inform the Trustee in writing of the effective date of any Resale Registration Statement registering the Securities under the Securities Act. The Trustee shall not be liable for any action taken or omitted to be taken by it in good faith in accordance with the aforementioned Resale Registration Statement.

As used in the preceding two paragraphs of this Section 3.05, the term “transfer” encompasses any sale, pledge, transfer or other disposition of any Restricted Security.

(c) Neither the Trustee nor any of its agents shall (i) have any duty to monitor compliance with or with respect to any federal or state or other securities or tax laws or (ii) have any duty to obtain documentation on any transfers or exchanges other than as specifically required hereunder.

Section 3.06. Mutilated, Destroyed, Lost And Stolen Securities. If any mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of like tenor and Principal Amount and bearing a number not contemporaneously outstanding.

If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity satisfactory to them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of like tenor and Principal Amount and bearing a number not contemporaneously outstanding.

In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security.

Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.

Every new Security issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities duly issued hereunder.

The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities.

Section 3.07. Persons Deemed Owners. Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary.

Section 3.08. Book-entry Provisions For Global Securities. (a) The Global Securities initially shall (i) be registered in the name of the Depositary or the nominee of such Depositary, (ii) be delivered to the Trustee as custodian for the Depositary and (iii) bear legends as set forth on the face of the form of Security in Section 2.02.

Members of, or participants in, the Depositary (“Agent Members”) shall have no rights under this Indenture with respect to any Global Security held on their behalf by the Depositary, or the Trustee as its custodian, or under the Global Security, and the Depositary may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of the Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of any Holder.

(b) Transfers of the Global Securities shall be limited to transfers in whole, but not in part, to the Depositary, its successors or their respective nominees. Interests of beneficial owners in a Global Security may be transferred or exchanged, in whole or in part, for Physical Securities in accordance with the rules and procedures of the Depositary and the provisions of Section 3.10. In addition, Physical Securities shall be transferred to all beneficial owners in exchange for their beneficial interests in the Global Securities if (A) such Depositary has notified the Company (or the Company becomes aware) that the Depositary (i) is unwilling or unable to continue as Depositary for such Global Security or (ii) has ceased to be a clearing agency registered under the Exchange Act when the Depositary is required to be so registered to act as such Depositary and, in both such cases, no successor Depositary shall have been appointed within 90 days of such notification or of the Company becoming aware of such event or (B) there shall have occurred and be continuing an Event of Default with respect to such Global Security and the Outstanding Securities shall have become due and payable pursuant to Section 5.02 and the Trustee requests that Physical Securities be issued; provided that Holders of Physical Securities offered and sold in reliance on Rule 144A shall have the right, subject to applicable law, to request that such Securities be exchanged for interests in the applicable Global Security.

(c) In connection with any transfer or exchange of a portion of the beneficial interest in the Global Security to beneficial owners pursuant to paragraph (b), the Security Registrar shall (if one or more Physical Securities are to be issued) reflect on its books and records the date and a decrease in the Principal Amount of the Global Security in an amount equal to the Principal Amount of the beneficial interest in the Global Security to be transferred, and the Company shall execute, and the Trustee shall authenticate and deliver, one or more Physical Securities of like tenor and amount.

(d) In connection with the transfer of the entire Global Security to beneficial owners pursuant to paragraph (b), the Global Security shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall authenticate and deliver, to each beneficial owner identified by the Depositary in exchange for its beneficial interest in the Global Security, an equal aggregate Principal Amount of Physical Securities of authorized denominations and the same tenor.

(e) Any Physical Security constituting a Restricted Security delivered in exchange for an interest in the Global Security pursuant to paragraph (c) or (d) shall, except as otherwise provided by paragraphs (a)(i)(x) and (c) of Section 3.10, bear the legend regarding transfer restrictions applicable to the Physical Securities set forth on the face of the form of Security in Section 2.02.

(f) The Holder of the Global Securities may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Securities.

Section 3.09. Cancellation. The Company at any time may deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the Trustee for cancellation any Securities previously authenticated hereunder which the Company has not issued and sold. The Trustee shall cancel and dispose of all Securities surrendered for registration of transfer, exchange, payment, purchase, repurchase, redemption, conversion (pursuant to Article 13 hereof) or cancellation in accordance with its customary practices. If the Company shall acquire any of the Securities, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Securities unless and until the same are delivered to the Trustee for cancellation. The Company may not issue new Securities to replace Securities it has paid in full or delivered to the Trustee for cancellation.

Section 3.10. Special Transfer Provision. (a) Transfers to Non-U.S. Persons. The following provisions shall apply with respect to the registration of any proposed transfer of a Security constituting a Restricted Security to any Non-U.S. Person to which Securities in the form of Global Securities cannot be issued:

(i) the Security Registrar shall register the transfer of any Security constituting a Restricted Security, whether or not such Security bears the legend required by Section 2.02 and 2.05, if (x) the requested transfer is after July 14, 2005 or (y) the proposed transferor has delivered to the Security Registrar a

certificate substantially in the form of Exhibit A hereto, together with such other certifications, legal opinions or other information as the Company may reasonably require to confirm that such transfer is being made pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act; and

(ii) if the proposed transferor is an Agent Member holding a beneficial interest in the Global Security, upon receipt by the Security Registrar of the certificate, if any, required by paragraph (i) above and instructions given in accordance with the Depositary’s and the Security Registrar’s procedures,

whereupon (1) the Security Registrar shall reflect on its books and records the date and (if the transfer does not involve a transfer of outstanding Physical Securities) a decrease in the Principal Amount of the Global Security in an amount equal to the Principal Amount of the beneficial interest in the Global Security to be transferred, and (2) the Company shall execute and the Trustee shall authenticate and deliver one or more Physical Securities of like tenor and amount.

(b) Transfers to QIBs. The following provisions shall apply with respect to the registration of any proposed transfer of a Security constituting a Restricted Security to a QIB (excluding transfers to Non-U.S. Persons):

(i) the Security Registrar shall register the transfer if such transfer is being made by a proposed transferor who has checked the box provided for on the form of Security stating, or has otherwise advised the Company and the Security Registrar in writing, that the sale has been made in compliance with the provisions of Rule 144A to a transferee who has signed the certification provided for on the form of Security stating, or has otherwise advised the Company and the Security Registrar in writing, that it is purchasing the Security for its own account or an account with respect to which it exercises sole investment discretion and that it and any such account is a QIB within the meaning of Rule 144A, and is aware that the sale to it is being made in reliance on Rule 144A and acknowledges that it has received such information regarding the Company as it has requested pursuant to Rule 144A or has determined not to request such information and that it is aware that the transferor is relying upon its foregoing representations in order to claim the exemption from registration provided by Rule 144A; and

(ii) if the proposed transferee is an Agent Member, and the Securities to be transferred consist of Physical Securities which after transfer are to be evidenced by an interest in the Global Security, upon receipt by the Security Registrar of instructions given in accordance with the Depositary’s and the Security Registrar’s procedures, the Security Registrar shall reflect on its books and records the date and an increase in the Principal Amount of the Global Security in an amount equal to the Principal Amount of the Physical Securities to be transferred, and the Trustee shall cancel the Physical Securities so transferred.

(c) Private Placement Legend. Upon the registration of transfer, exchange or replacement of Securities not bearing the legends required by Section 2.02 and 2.05, the Security Registrar shall deliver Securities that do not bear such legends. Upon the registration of transfer, exchange or replacement of Securities bearing the legends required by Section 2.02 and 2.05, the Security Registrar shall deliver only Securities that bear such legends unless (i) the circumstance contemplated by paragraph (a)(i)(x) of this Section 3.10 exists or (ii) there is delivered to the Security Registrar an Opinion of Counsel reasonably satisfactory to the Company and the Trustee to the effect that neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities Act.

(d) General. By its acceptance of any Security bearing the legends required by Section 2.02 and 2.05, each Holder of such a Security acknowledges the restrictions on transfer of such Security set forth in this Indenture and in such legends and agrees that it will transfer such Security only as provided in this Indenture.

The Security Registrar shall retain, in accordance with its customary procedures, copies of all letters, notices and other written communications received pursuant to this Section 3.10. The Company shall have the right to inspect and make copies of all such letters, notices or other written communications at any reasonable time upon the giving of reasonable written notice to the Security Registrar.

Section 3.11. CUSIP Numbers. The Company in issuing the Securities may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice and that reliance may be placed only on the other identification numbers printed on the Securities, and any such notice shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee of any change in the “CUSIP” numbers.

Section 3.12. Ranking. The indebtedness of the Company arising under or in connection with this Indenture and every Outstanding Security issued under this Indenture from time to time constitutes and will constitute a senior unsecured general obligation of the Company, ranking equally with other existing and future senior unsecured and unsubordinated Indebtedness of the Company and ranking senior in right of payment to any future Indebtedness of the Company that is expressly made subordinate to the Securities by the terms of such Indebtedness. For purposes of this Section 3.12 only, “Indebtedness” means, without duplication, the principal or face amount of (i) all obligations for borrowed money, (ii) all obligations evidenced by debentures, notes or other similar instruments, (iii) all obligations in respect of letters of credit or bankers acceptances or similar instruments (or reimbursement obligations with respect thereto), (iv) all obligations to pay the deferred purchase price of property or services, (v) all obligations as lessee which are capitalized in accordance with generally accepted accounting principles, and (vi) all Indebtedness of others guaranteed by the Company or any of its Subsidiaries or for which the Company or any of its Subsidiaries is legally responsible or liable (whether by agreement to purchase indebtedness of, or to supply funds or to invest in, others).

Section 4.02. Application Of Trust Money. Subject to the provisions of the last paragraph of Section 10.03, all money deposited with the Trustee pursuant to Section 4.01 shall be held in trust and applied by it, in accordance with the provisions of the Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal and Liquidated Damages Amounts, if any, for whose payment such money has been deposited with the Trustee.

ARTICLE 5

REMEDIES

Section 5.01. Events Of Default. “Event of Default”, wherever used herein, means any one of the following events (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):

(e) failure by the Company to give the Change of Control Company Notice within 30 days of the occurrence of the Change of Control; or

(f) in the event of either (i) the failure of the Company or any of its significant subsidiaries to make any payment by the end of the applicable grace period, if any, after the final scheduled payment date for such payment with respect to any indebtedness for borrowed money in an aggregate principal amount in excess of US$15,000,000, or (ii) the acceleration of indebtedness for borrowed money of the Company or any of its significant subsidiaries in an aggregate amount in excess of US$15,000,000 due to a default with respect to such indebtedness, without such indebtedness referred to in either (i) or (ii) above having been discharged, cured, waived, rescinded or annulled, for a period of 30 days after there has been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by Holders of at least 25% in aggregate Principal Amount of the Securities a written notice specifying such default and requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder; or

Section 5.02. Acceleration Of Maturity; Rescission And Annulment. (a) If an Event of Default (other than those specified in Section 5.01(g) and 5.01(h)) occurs and is continuing, then and in every such case the Trustee or the Holders of not less than 25% in aggregate Principal Amount of the Outstanding Securities may declare the Principal Amount (or premium, if any) plus Liquidated Damages Amounts, if any, on all the Outstanding Securities to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any such declaration such Principal Amount plus accrued but unpaid Liquidated Damages Amounts, if any, shall become immediately due and payable. If an Event of Default is cured prior to any such declaration by the Trustee or the Holders, the Trustee and the Holders shall not be entitled to declare the Securities due and payable as provided herein as a result of such cured Event of Default and any such cured Event of Default shall be deemed waived by the Holders and the Trustee.

Notwithstanding the foregoing, in the case of an Event of Default specified in Section 5.01(g) or 5.01(h), the Principal Amount plus accrued but unpaid Liquidated Damages Amounts, if any, on all Outstanding Securities will ipso facto become due and payable without any declaration or other Act on the part of the Trustee or any Holder.

(b) At any time after such a declaration of acceleration has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in aggregate Principal Amount of the Outstanding Securities, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if:

(i) the Company has paid or deposited with the Trustee a sum sufficient to pay

(A) the Principal Amount plus accrued but unpaid Liquidated Damages Amounts, if any, or the Redemption Price or Repurchase Price, as applicable, on any Securities which have become due otherwise than by such declaration of acceleration, and

(B) all sums paid or advanced by the Trustee hereunder and the compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 6.07; and

(ii) all Events of Default, other than the non-payment of the Principal Amount plus accrued but unpaid Liquidated Damages Amounts, if any, on Securities which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 5.13.

No such rescission shall affect any subsequent default or impair any right consequent thereon.

Section 5.03. Other Remedies. If an Event of Default occurs and is continuing, the Trustee may, but shall not be obligated to, pursue any available remedy to collect the payment of the Principal Amount plus accrued but unpaid Liquidated Damages Amounts, if any, on the Securities or to enforce the performance of any provision of the Securities or this Indenture. The Trustee may maintain a proceeding even if the

Trustee does not possess any of the Securities or does not produce any of the Securities in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of, or acquiescence in, the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative.

Section 5.04. Collection Of Indebtedness And Suits For Enforcement By Trustee. (a) The Company covenants that if:

(i) default is made in the payment of any Liquidated Damages Amounts on any Security when such amounts become due and payable, and such default continues for a period of 30 days, or

(ii) default is made in the payment of the Principal Amount plus accrued but unpaid Liquidated Damages Amounts, if any, at the Stated Maturity thereof or in the payment of the Redemption Price or Repurchase Price in respect of any Security,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then due and payable on such Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

Payments of principal, premium, if any, and Liquidated Damages Amounts, if any, or the Redemption Price or Repurchase Price on the Securities, if any, that are not made when due will accrue interest at the annual rate of 1% above the then applicable interest rate from the required payment date.

Section 5.05. Trustee May File Proofs Of Claim. In case of any judicial proceeding relative to the Company (or any other obligor upon the Securities), its property or its creditors, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such proceeding. In particular, the Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official 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 shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and any other amounts due the Trustee under Section 6.07.

No provision of this Indenture shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 5.06. Application Of Money Collected. Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money to Holders, upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

FIRST: To the payment of all amounts due the Trustee under Section 6.07; and

SECOND: To the payment of the amounts then due and unpaid on the Securities for the Principal Amount, Redemption Price, Repurchase Price or Liquidated Damages Amounts, if any, as the case may be, in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities.

Section 5.07. Limitation On Suits. No Holder of any Security shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder (other than in the case of an Event of Default specified in

it being understood and intended that no one or more Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other Holders, or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all the Holders.

Section 5.08. Unconditional Right Of Holders To Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of the Principal Amount, Redemption Price, Repurchase Price or Liquidated Damages Amounts, if any, in respect of the Securities held by such Holder, on or after the respective due dates expressed in the Securities or on or after any Redemption Date or Repurchase Date, as applicable, and to convert the Securities in accordance with Article 13, or to bring suit for the enforcement of any such payment on or after such respective dates or the right to convert, shall not be impaired or affected adversely without the consent of such Holder.

Section 5.10. Rights And Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 3.06, 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 5.11. Delay Or Omission Not Waiver. No delay or omission of the Trustee or of any Holder of any Security 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 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 or by the Holders, as the case may be.

Section 5.12 . Control By Holders. The Holders of a majority in Principal Amount of the Outstanding

(ii) in respect of a covenant or provision hereof which under Article 9 cannot be modified or amended without the consent of the Holder of each Outstanding Security affected.

Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

Section 5.14. Undertaking For Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, in either case in respect of the Securities, a court may require any party litigant in such suit to file an undertaking to pay the costs of the suit, and the court may assess reasonable costs, including reasonable attorney’s fees, against any party litigant in the suit having due regard to the merits and good faith of the claims or defenses made by the party litigant; but the provisions of this Section shall not apply to any suit instituted by the Company, 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 Principal Amount of the Outstanding Securities, to any suit by any Holder pursuant to Section 5.08 or to any suit instituted by any Holder for the enforcement of the payment of the Principal Amount or accrued but unpaid Liquidated Damages Amounts, if any, on any Security on or after Maturity of such Security or the Redemption Price or Repurchase Price.

Section 5.15. Waiver Of Stay Or Extension Laws.

In case an Event of Default with respect to the Securities has occurred (which has not been cured or waived), the Trustee shall exercise the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs. Notwithstanding the foregoing, no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers.

Section 6.03. Certain Rights Of Trustee. Subject to the provisions of Section 6.01:

(a) the Trustee may conclusively rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties;

(e) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders pursuant to this Indenture, unless such Holders shall have offered to the Trustee security or indemnity satisfactory to it against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction;

(f) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document (including mathematical calculations), but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit; and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney at the sole cost of the Company and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation.

(g) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder;

(h) the Trustee shall not be charged with knowledge of any Default or Event of Default with respect to the Securities unless either (i) a Responsible Officer shall have actual knowledge of such Default or Event of Default or (ii) written notice of such Default or Event of Default shall have been given to the Trustee by the Company or any other obligor on such Securities or by any Holder of such Securities;

(i) the Trustee shall not be liable for any action taken, suffered or omitted by it in good faith and reasonably believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Indenture;

(k) the Trustee may request that the Company deliver an Officers’ Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which Officers’ Certificate may be signed by any person authorized to sign an Officers’ Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded.

Section 6.04. Not Responsible For Recitals. The recitals contained herein and in the Securities, except the Trustee’s certificates of authentication, shall be taken as the statements of the Company, and the Trustee assumes no responsibility for their correctness.

The Trustee shall not be accountable for the use or application by the Company of Securities or the proceeds thereof.

Section 6.05. May Hold Securities. The Trustee, any Paying Agent, any Security Registrar or any other agent of the Company, in its individual or any other capacity, may become the owner or pledgee of Securities and, subject to Section 6.08 and 6.13, may otherwise deal with the Company with the same rights it would have if it were not Trustee, Paying Agent, Security Registrar or such other agent.

Section 6.06. Money Held In Trust. Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law.

(ii) except as otherwise expressly provided herein, to reimburse the Trustee upon its request for all expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the compensation and the expenses and disbursements of its agents and counsel properly incurred), except any such expense, disbursement or advance as may be attributable to its negligence or bad faith; and

(iii) to indemnify the Trustee and any predecessor Trustee for, and to hold it harmless against, any loss, liability or expense including taxes (other than taxes based upon, measured by or determined by the income of the Trustee) incurred without gross negligence or bad faith on its part, arising out of or in connection with the acceptance or administration of this trust, including the costs and expenses, properly incurred, of defending itself against any claim (whether assessed by the Company, by any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder.

The obligations of the Company under this Section 6.07 shall survive the resignation or removal of the Trustee and the satisfaction and discharge of this Indenture. To secure the Company’s payment obligations in this Section 6.07, the Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on the Securities. Such lien shall survive the resignation or removal of the Trustee and the satisfaction and discharge of this Indenture. When the Trustee incurs expenses or renders services after a Default or an Event of Default specified in Section 5.01(e) and 5.01(f) hereof occurs, the expenses and the compensation for the services (including, the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under U.S. Code, Title 11 or any other similar foreign, federal or state law for the relief of debtors.

Section 6.08. Disqualification; Conflicting Interests. If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture.

Section 6.09. Corporate Trustee Required; Eligibility. There shall at all times be a Trustee hereunder which shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such and has a combined capital and surplus of at least $50,000,000. If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article.

Section 6.10. Resignation And Removal; Appointment Of Successor. (a) No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee under Section 6.11.

(b) The Trustee may resign at any time by giving written notice thereof to the Company.

(c) The Trustee may be removed at any time by Act of the Holders of a majority in Principal Amount of the Outstanding Securities, delivered to the Trustee and to the Company. If an instrument of acceptance by a successor Trustee shall not have been delivered to the Trustee within 30 days after the notice of removal, the Trustee being removed may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities.

(d) If at any time:

(i) the Trustee shall fail to comply with Section 6.08 after written request therefor by the Company or by any Holder who has been a bona fide Holder of a Security for at least six months, or

(ii) the Trustee shall cease to be eligible under Section 6.09 and shall fail to resign after written request therefor by the Company or by any such Holder, or

(iii) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent, or

(iv) a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation,

then, in any such case, (A) the Company by a Company Order may remove the Trustee, or (B) subject to Section 5.14 , any Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of such Holder and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

(e) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, the Company, by a Company Order, shall promptly appoint a successor Trustee. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee shall be appointed by Act of the Holders of a majority in Principal Amount of the Outstanding Securities delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment, become the successor Trustee and supersede the successor Trustee appointed by the Company. If no successor Trustee shall have been so appointed by the Company or the Holders and accepted appointment in the manner hereinafter provided, any Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee.

(f) The Company shall give notice of each resignation and each removal of the Trustee and each appointment of a successor Trustee to all Holders in the manner provided in Section 1.06. Each notice shall include the name of the successor Trustee and the address of its Corporate Trust Office.

Section 6.11. Acceptance Of Appointment By Successor. Every successor Trustee appointed hereunder shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder. Upon request of any such successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts.

No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article.

Section 6.12. Merger, Conversion, Consolidation Or Succession To Business. Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities.

Section 6.13. Preferential Collection Of Claims Against. If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Securities), the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of claims against the Company (or any such other obligor).

Section 10.01. Payments. The Company shall duly and punctually make all payments in respect of the Securities in accordance with the terms of the Securities and this Indenture.

Any payments made or due pursuant to this Indenture shall be considered paid on the applicable date due if by 10:00 a.m., New York City time, on such date the Paying Agent holds, in accordance with this Indenture, cash or securities, if permitted hereunder, sufficient to pay all such amounts then due. Payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts or in Applicable Stock, as the case may be.

Section 10.02. Maintenance Of Office Or Agency. The Company shall maintain in the Borough of Manhattan, The City of New York, an office or agency where Securities may be presented or surrendered for payment, where Securities may be surrendered for registration of transfer, exchange, redemption, repurchase or conversion and where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served, which shall initially be the Corporate Trust Office of the Trustee. The Company shall 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 of the Trustee, and the Company hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands.

The Company may also from time to time designate one or more other offices or agencies (in or outside the Borough of Manhattan, The City of New York) where the Securities may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of Manhattan, The City of New York, for such purposes. The Company shall 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.

Section 10.03. Money For Security Payments To Be Held In Trust. If the Company shall at any time act as its own Paying Agent, it shall, on or before each due date of any payment in respect of any of the Securities, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to make the payment so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and shall promptly notify the Trustee of its action or failure so to act.

Whenever the Company shall have one or more Paying Agents, it will, at least one Business Day prior to each due date of any payment in respect of any Securities, deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be held as provided by the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act.

The Company shall cause each Paying Agent other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will (i) comply with the provisions of the Trust Indenture Act applicable to it as a Paying Agent and (ii) during the continuance of any default by the Company (or any other obligor upon the Securities) in the making of any payment in respect of the Securities, upon the written request of the Trustee, forthwith pay to the Trustee all sums held in trust by such Paying Agent as such.

The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money.

Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the making of payments in respect of any Security and remaining unclaimed for two years after such payment has become due shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in The City of New York, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining shall be repaid to the Company.

Section 10.04. Statement By Officers As To Default. The Company shall deliver to the Trustee, within 120 days after the end of each fiscal year of the Company ending after the date hereof, an Officers’ Certificate, stating whether or not to the knowledge of the signers thereof the Company is in Default in the performance and observance of any of the terms, provisions and conditions of this Indenture (without regard to any period of grace or requirement of notice provided hereunder) and, if the Company shall be in Default, specifying all such Defaults and the nature and status thereof of which they may have knowledge.

The Company shall deliver to the Trustee, as soon as possible and in any event within five days after the Company becomes aware of the occurrence of any Event of Default or an event which, with notice or the lapse of time or both, would constitute an Event of Default, an Officers’ Certificate setting forth the details of such Event of Default or default and the action which the Company proposes to take with respect thereto.

Section 10.05. Existence. Subject to Article 8, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its existence, rights (charter and statutory) and franchises; provided, however, that the Company shall not be required to preserve any such right or franchise if the Board of Directors of the Company shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and that the loss thereof is not disadvantageous in any material respect to the Holders.

Section 10.06. Reports And Delivery Of Certain Information. Whether or not required by the rules and regulations of the Commission, so long as any Securities are Outstanding, the Company shall promptly furnish to the Trustee (i) all quarterly and annual financial information that is substantially equivalent to that which would be required to be contained in a filing with the Commission on Forms 10-Q and 10-K if the Company were required to file such Forms, including a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section and, with respect to the annual information only, a report thereon by the Company’s certified independent accountants and (ii) all reports that are substantially equivalent to that which would be required to be filed with the Commission on Form 8-K if the Company were required to file such reports; provided that in each case the delivery of materials to the Trustee by electronic means shall be deemed to be “furnished” to the Trustee for purposes of this Section 10.06. Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates). In addition, whether or not required by the rules and regulations of the Commission, the Company shall file a copy of all such information with the Commission for public availability (unless the Commission will not accept such a filing) and make such information available to investors who request it in writing. So long as any of the Securities remain Outstanding, the Company shall make available the information required by Rule 144A(d)(4) under the Securities Act to any Holder or any beneficial owner of Securities or holder or beneficial owner of shares of Common Stock, or to a prospective purchaser of any such security designated by any such holder, as the case may be, to the extent required to permit compliance by such Holder or holder with Rule 144A under the Securities Act in connection with the resale of any such security.

Section 10.07. Resale Of Certain Securities. During the period beginning on the Issue Date and ending on the date that is two years from the Issue Date, the Company shall not resell any Securities which constitute “restricted securities” under Rule 144 that have been reacquired by any of them. The Trustee shall have no responsibility in respect of the Company’s performance of its agreement in the preceding sentence.

Section 10.08 Book-Entry System. If the Securities cease to trade in the Depositary’s book-entry settlement system, the Company covenants and agrees that it shall use reasonable efforts to make such other book–entry arrangements that it determines are reasonable for the Securities.

Section 10.9. Liquidated Damages Amounts Under The Registration Rights Agreement. If at any time Liquidated Damages Amounts become payable by the Company pursuant to the Registration Rights Agreement, the Company shall promptly deliver to the Trustee a certificate to that effect and stating (i) the amount of such Liquidated Damages Amounts that are payable and (ii) the date on which such Liquidated Damages Amounts are payable pursuant to the terms of the Registration Rights Agreement. Unless and until a Responsible Officer of the Trustee receives such a certificate, the Trustee may assume without inquiry that no Liquidated Damages Amounts are payable. If the Company has paid Liquidated Damages Amounts directly to the Persons entitled to such Liquidated Damages Amounts, the Company shall deliver to the Trustee a certificate setting forth the particulars of such payment.

Section 10.10. Information For IRS Filings. The Company shall provide to the Trustee on a timely basis

such information as the Trustee requires to enable the Trustee to prepare and file any form required to be submitted by the Company with the Internal Revenue Service and the Holders of the Securities.

Section 10.11. Further Instruments And Acts. Upon reasonable request of the Trustee, or as otherwise necessary, the Company will execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of this Indenture.

(a) General. The Company may choose to redeem the Securities at any time on or after July 14, 2008, in whole or in part, at a redemption price equal to one hundred percent (100%) of the Principal Amount (the “Redemption Price”) of the Securities to be redeemed if:

(i) the Sale Price of the Common Stock, as calculated by the Company, for each of the thirty (30) consecutive Trading Days preceding the day on which the Company mails the Redemption Notice is equal to at least one hundred thirty percent (130%) of the Conversion Price; or

(ii) at such time at least ninety percent (90%) of the initial aggregate Principal Amount of all of the Securities has been converted, repurchased or redeemed.

(b) Redemption Notice. The Company may exercise its rights specified in Section 11.01(a) upon delivery of a written notice of redemption (a “Redemption Notice”), on any date that the requirements of Section 11.01(a) are met, stating:

(i) the certificate numbers of the Securities which the Company is electing to redeem;

(iii) that each such Security shall be redeemed with respect to the Redemption Date pursuant to the terms and conditions specified in the Securities and in this Indenture;

(iv) the date on which the redemption shall occur (the “Redemption Date”), which shall not be less than thirty (30) days, nor more than sixty (60) days, after the mailing of the Redemption Notice;

(v) the Redemption Price;

(vii) that Securities subject to the Redemption Notice must be surrendered to the Paying Agent for cancellation to collect payment;

The Company shall, no later than the Business Day immediately prior to the Redemption Date, deposit with the Trustee or with the Paying Agent (or if the Company or a Subsidiary or an Affiliate of any of them is acting as the Paying Agent, shall segregate and hold in trust as provided herein) an amount of cash (in immediately available funds if deposited on such Business Day) sufficient to pay the aggregate Redemption Price of all the Securities or portions thereof which are to be redeemed on such Redemption Date. Upon the later of the receipt by the Paying Agent of the aggregate Redemption Price and the Redemption Date, the Securities subject to the Redemption Notice will cease to be Outstanding, and the rights of the Holders in respect thereof shall terminate (other than the right to

receive the Redemption Price upon delivery of such Securities).

Provisions of this Indenture that apply to the redemption of all of a Security also apply to the redemption of such portion of such Security.

Section 11.02. Repurchase Of Securities At Option Of The Holder.

(a) General. The Securities shall be repurchased by the Company at the option of the Holder, in whole or in part, at a purchase price equal to one hundred percent (100%) of the Principal Amount of the Securities to be repurchased (the “Optional Repurchase Price”), subject to satisfaction by or on behalf of any Holder of the requirements set forth in Section 11.02(b), on July 14, 2007, July 14, 2013, and July 14, 2018 (each an “Optional Repurchase Date”).

(b) Optional Repurchase Notice. A Holder may exercise its right specified in Section 11.02(a) by delivery, no less than thirty (30) days and no more than sixty (60) days prior to the Optional Repurchase Date on which it wishes the Securities to be repurchased, of a written notice of repurchase (an “Optional Repurchase Notice”), substantially in the form of Exhibit B hereto, stating:

The delivery of such Security to the Paying Agent with, or at any time after delivery of, the Optional Repurchase Notice (together with all necessary endorsements) at the offices of the Paying Agent shall be a condition to the receipt by the Holder of the Optional Repurchase Price therefor; provided, however, that such Optional Repurchase Price shall be so paid pursuant to this Section 11.02 only if the Security so delivered to the Paying Agent shall conform in all respects to the description thereof set forth in the related Optional Repurchase Notice.

The Company shall repurchase from the Holder thereof, pursuant to this Section 11.02, a portion of a Security, so long as the Principal Amount of such portion is $1,000 or an integral multiple thereof. Provisions of this Indenture that apply to the repurchase of all of a Security also apply to the repurchase of such portion of such Security.

Any repurchase by the Company contemplated pursuant to the provisions of this Section 11.02 shall be consummated by the delivery of the consideration to be received by the Holder promptly following the later of the Optional Repurchase Date and the time of delivery of the Security.

Notwithstanding anything contained herein to the contrary, any Holder delivering to the Paying Agent the Optional Repurchase Notice contemplated by this Section 11.02(b) shall have the right to withdraw such Optional Repurchase Notice at any time prior to the close of business on the Business Day immediately preceding the Optional Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 11.05.

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

Section 11.03. Repurchase Of Securities At Option Of The Holder Upon Change of Control.

(a) General.

(i) If at any time prior to the Maturity Date there shall have occurred a Change of Control, Securities shall be purchased by the Company at the option of the Holder, in whole or in part, as of the date that is 30 days after the date of the mailing of the Change of Control Company Notice under Section 11.03(b) (the “Change of Control Repurchase Date”) at a purchase price equal to 100% of the Principal Amount of the Securities to be repurchased, together with interest accrued and unpaid, but excluding, the Change of Control Repurchase Date (the “Change of Control Repurchase Price “), subject to satisfaction by or on behalf of any Holder of the requirements set forth in Section 11.03(c).

(ii) Subject to the fulfillment by the Company of the conditions set forth in Section 11.04(d) below, the Company may elect to pay the Change of Control Repurchase Price in Common Stock by delivering the number of shares of Applicable Stock equal to (i) the Change of Control Repurchase Price divided by (ii) 95% of the average of the Sale Price of the Applicable Stock for the five consecutive Trading Days immediately preceding and including the third Trading Day immediately preceding the Change of Control Repurchase Date. A “Change of Control” shall be deemed to have occurred at such time after the Issue Date of the Securities when the following has occurred:

(1)

any “person” or “group” (as such terms are used in Section 13(d) and 14(d) of the Exchange Act, acquires the beneficial ownership (as defined in Rules 13d-3 and 13d-5 under the Exchange Act, except that a person shall be deemed to have “beneficial ownership” of all securities that such person has the right to acquire, whether such right is exercisable immediately or only after the passage of time), directly or indirectly, through a purchase, merger or other acquisition transaction, of 50% or more of the total voting power of the total outstanding voting stock of the Company or any of the Company’s significant subsidiaries, other than an acquisition by the Company, any of its subsidiaries or any of its employee benefit plans;

(2)

the Company or any of the Company’s significant subsidiaries consolidates with or merges with or into another Person or conveys, transfers, leases or otherwise disposes of all or substantially all of its assets to any Person, or any Person consolidates with or merges with or into the Company or any of the Company’s significant subsidiaries, other than:

(x) any transaction (i) that does not result in any reclassifications, conversion, exchange or cancellation of outstanding shares of the capital stock of the Company or any of the Company’s significant subsidiaries and (ii) pursuant to which holders of the capital stock of the Company or any of the Company’s significant subsidiaries immediately prior to the transaction have the entitlement to exercise, directly or indirectly, 50% or more of the total voting power of all shares of such capital stock entitled to vote generally in the election of directors of the continuing or surviving Person immediately after the transaction; and

(y) any merger solely for the purpose of changing the Company’s or any of its significant subsidiaries’ jurisdiction of incorporation and resulting in a reclassification, conversion or exchange of outstanding Common Stock solely into shares of common stock of the surviving entity;

(3)

during any consecutive two-year period, individuals who at the beginning of such period constituted the Board of Directors of the Company or any of its significant subsidiaries (together with any new directors whose election to such Board of Directors, or whose nomination for election by stockholders, was approved by a vote of a majority of the

directors then still in office who were either directors at the beginning of such period or whose election or nomination for election was previously so approved) cease for any reason to constitute a majority of such Board of Directors; or

(4)

the stockholders of the Company or any of its significant subsidiaries pass a special resolution approving a plan of liquidation or dissolution and no additional approvals of stockholders are required under applicable laws to cause a liquidation or dissolution.

(b) Notice of Change of Control . Within 30 days after the occurrence of a Change of Control, the Company shall mail a written notice of Change of Control (the “Change of Control Company Notice”) by first-class mail to the Trustee and to each Holder (and to beneficial owners as required by applicable law). The notice shall include a form of Change of Control Repurchase Notice to be completed by the Securityholder and shall state:

(i) the events causing a Change of Control and the date of such Change of Control;

(ii) that the Holder has a right to require the Company to repurchase the Holder’s Securities;

(iii) the date by which the Change of Control Repurchase Notice pursuant to this Section 11.03 must be delivered to the Paying Agent in order for a Holder to exercise the Change of Control repurchase right;

(iv) the Change of Control Repurchase Date;

(v) the Change of Control Repurchase Price;

(vi) whether the Change of Control Repurchase Price will be paid in cash or shares of Applicable Stock, or a combination thereof and, in the case of a combination, the percentage of each;

(vii) if the Company elects to pay the Change of Control Repurchase Price in shares of Applicable Stock or a combination of cash and shares of Applicable Stock, that the number of shares of Applicable Stock each Holder will receive will equal the quotient obtained by dividing the amount of the Change of Control Repurchase Price to be paid in shares of Applicable Stock by 95% of the average of the Sale Price of the Applicable Stock for the five consecutive Trading Days immediately preceding and including the third Trading Day immediately preceding the Change of Control Repurchase Date;

(viii) if the Company elects to pay the Change of Control Repurchase Price in shares of Applicable Stock or a combination of cash and shares of Applicable Stock, the method of calculating the Sale Price of the shares of Applicable Stock;

(ix) that because the Sale Price of the shares of Applicable Stock will be determined prior to the Change of Control Repurchase Date, Holders of the Securities will bear the market risk that the shares of Applicable Stock to be received will decline in value between the date such Sale Price is determined and the Change of Control Repurchase Date;

(x) the name and address of the Paying Agent and the Conversion Agent;

(xi) the Conversion Price applicable on the Change of Control Company Notice Date;

(xii) that Securities as to which a Change of Control Repurchase Notice has been given may be converted pursuant to Article 13 hereof only if the Change of Control Repurchase Notice has been withdrawn in accordance with the terms of this Indenture;

(xiii) that Securities must be surrendered to the Paying Agent for cancellation to collect payment;

(xiv) that the Change of Control Repurchase Price for any Security as to which a Change of Control Repurchase Notice has been duly given and not withdrawn will be paid promptly following the later of the

Change of Control Repurchase Date and the time of surrender of such Security as described in (xiii);

(xv) the procedures the Holder must follow to exercise rights under this Section 11.03;

(xvi) the conversion rights, if any, of the Securities;

(xvii) the procedures for withdrawing a Change of Control Repurchase Notice; and

(xviii) the CUSIP number of the Securities.

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

(c) Change of Control Repurchase Notice. A Holder may exercise its right specified in Section 11.03(a) upon delivery of a written notice of repurchase (a “Change of Control Repurchase Notice”), substantially in the form of Exhibit C hereto, at any time from the opening of business on the date of the Change of Control Company Notice until the close of business on the Change of Control Repurchase Date, stating:

(i) the certificate number of the Security which the Holder will deliver to be repurchased;

(ii) the portion of the Principal Amount of the Security which the Holder will deliver to be repurchased, which portion must be in a Principal Amount of $1,000 or an integral multiple thereof;

(iii) that such Security shall be repurchased with respect to the Change of Control Repurchase Date pursuant to the terms and conditions specified in the Securities and in this Indenture;

(iv) payment instructions for the payment of cash and share delivery instructions for shares of Applicable Stock (as applicable); and

(v) in the event the Company elects, pursuant to Section 11.04, to pay the Change of Control Repurchase Price, in whole or in part, in shares of Applicable Stock but such portion of the Change of Control Repurchase Price shall ultimately be paid to such Holder entirely in cash because any of the conditions to payment of the Change of Control Repurchase Price in shares of Applicable Stock is not satisfied prior to 5:00 p.m. (New York City time) on the Business Day immediately preceding the Change of Control Repurchase Date, as set forth in Section 11.04, whether such Holder elects to (A) withdraw such Change of Control Repurchase Notice as to some or all of the Securities to which such Change of Control Repurchase Notice relates (stating the principal amount and certificate numbers, if any, or the appropriate Depositary procedures, if applicable, of the Securities as to which such withdrawal shall relate), or (B) receive cash in respect of the entire Change of Control Repurchase Price for all Securities (or portions thereof) to which such Change of Control Repurchase Notice relates.

The delivery of such Security to the Paying Agent with, or at any time after delivery of, the Change of Control Repurchase Notice (together with all necessary endorsements) at the offices of the Paying Agent shall be a condition to the receipt by the Holder of the Change of Control Repurchase Price therefor; provided, however, that such Change of Control Repurchase Price shall be so paid pursuant to this Section 11.03 only if the Security so delivered to the Paying Agent shall conform in all respects to the description thereof set forth in the related Change of Control Repurchase Notice.

If a Holder, in such Holder’s Change of Control Repurchase Notice and in any written notice of withdrawal delivered by such Holder pursuant to the terms of Section 11.05, fails to indicate such Holder’s choice with respect to the election set forth in Section 11.03(c)(v), such Holder shall be deemed to have elected to receive cash in respect of the entire Change of Control Repurchase Price for all Securities subject to such Change of Control Repurchase Notice in the circumstances set forth in such Section 11.03(c)(v).

The Company shall repurchase from the Holder thereof, pursuant to this Section 11.03, a portion of a Security, so long as the Principal Amount of such portion is $1,000 or an integral multiple thereof. Provisions of this Indenture that apply to the repurchase of all of a Security also apply to the repurchase of such portion of such Security.

Any repurchase by the Company contemplated pursuant to the provisions of this Section 11.03 shall be consummated by the delivery of the consideration to be received by the Holder promptly following the later of the Change of Control Repurchase Date and the time of delivery of the Security; provided, however, that if the Change of Control Repurchase Notice is delivered after a date which is two Business Days prior to the Change of Control Repurchase Date, such payment may be made as promptly after such Change of Control Repurchase Date as is practicable.

Notwithstanding anything contained herein to the contrary, any Holder delivering to the Paying Agent the Change of Control Repurchase Notice contemplated by this Section 11.03(c) shall have the right to withdraw such Change of Control Repurchase Notice at any time prior to the close of business on the Business Day immediately preceding the Change of Control Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 11.05.

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

Section 11.04. The Company’s Right To Elect Manner Of Payment Of Change of Control Repurchase Price. (a) The Securities to be repurchased with respect to any Change of Control Repurchase Date pursuant to Section 11.03(a) may be paid for at the election of the Company in cash or shares of Applicable Stock, or in any combination of cash and shares of Applicable Stock, subject to the conditions set forth in Section 11.04(b). The Company shall designate, in the notice of Change of Control delivered pursuant to Section 11.03(b), whether the Company will repurchase the Securities for cash or shares of Applicable Stock, or, if a combination thereof, the percentages of the Change of Control Repurchase Price in respect of which it will pay in cash or shares of Applicable Stock; provided, however, that the Company will pay cash for fractional interests in shares of Applicable Stock. For purposes of determining the existence of potential fractional interests, all Securities subject to repurchase by the Company held by a Holder shall be considered together (no matter how many separate certificates are to be presented). Each Holder whose Securities are repurchased pursuant to Section 11.03 shall receive the same percentage of cash or shares of Applicable Stock in payment of the Change of Control Repurchase Price for such Securities, except (i) as provided in this Section 11.04(a) with regard to the payment of cash in lieu of fractional shares of Applicable Stock and (ii) in the event that the Company is unable to purchase the Securities of a Holder or Holders for shares of Applicable Stock because any necessary qualifications or registrations of the shares of Applicable Stock under applicable securities laws cannot be obtained, the Company may purchase the Securities of such Holder or Holders for cash. The Company may not change its election with respect to the consideration (or components or percentages of components thereof) to be paid once the Company has given its notice of Change of Control to Holders except in the event of a failure to satisfy, prior to 5:00 p.m. (New York City time), on the Business Day immediately preceding the Change of Control Repurchase Date, any condition to the payment of the Change of Control Repurchase Price in whole or in part, in shares of Applicable Stock.

(b) If the Company elects to pay the Change of Control Repurchase Price by delivering shares of Applicable Stock in lieu of cash or by delivering a combination of Applicable Stock and cash, the number of shares of Applicable Stock to be issued shall be equal to the relevant amount of the Change of Control Repurchase Price to be paid divided by 95% of the average of the Sale Prices of the Applicable Stock for the five consecutive Trading Days immediately preceding and including the third Trading Day immediately preceding the Change of Control Repurchase Date.

(c) The Company will not issue any fraction of a share of Applicable Stock in payment of the Change of Control Repurchase Price. Instead, the Company will make a cash payment (calculated to the nearest cent) equal to such fraction multiplied by the Sale Price of one share of Applicable Stock on the second Business Day immediately preceding the Change of Control Repurchase Date. If a Holder elects to have

more than one Security purchased, the number of shares of Applicable Stock shall be based on the aggregate amount of Securities to be purchased.

(d) The Company’s right to exercise its election to repurchase Securities through the issuance of shares of Applicable Stock shall be conditioned upon satisfaction of the following conditions prior to 5:00 p.m. (New York City time), on the Business Day immediately preceding the Change of Control Repurchase Date:

(i) the registration of such shares of Applicable Stock to be issued upon repurchase under the Securities Act and the Exchange Act, in each case, if required;

(ii) any qualification or registration of such shares of Applicable Stock to be issued upon repurchase under applicable state securities laws, if necessary, or the availability of an exemption from such qualification and registration;

(iii) the listing of such shares of Applicable Stock on a United States national securities exchange or the quotation of such shares of Applicable Stock on an inter-dealer quotation system of any registered United States national securities association; and

(iv) the receipt by the Trustee of an Officers’ Certificate stating (A): that the terms of the issuance of the shares of Applicable Stock are in conformity with this Indenture; (B) that the shares of Applicable Stock to be issued in payment of the Change of Control Repurchase Price in respect of Securities have been duly authorized and, when issued and delivered pursuant to the terms of this Indenture in payment of the Change of Control Repurchase Price in respect of Securities, will be validly issued, fully paid, non assessable and free from preemptive rights; (C) that the conditions above and the condition set forth in the second succeeding sentence have been satisfied in all material respects; and (D) the number of shares of Applicable Stock to be issued for each $1,000 Principal Amount of Securities and the Sale Price of a share of Applicable Stock on each Trading Day during the period commencing on the first Trading Day of the period during which the Sale Price is calculated and ending on the Trading Day immediately preceding the Change of Control Repurchase Date; and

(v) the receipt by the Trustee of an Opinion of Counsel stating that: (A) the shares of Applicable Stock to be issued by the Company in payment of the Change of Control Repurchase Price in respect of Securities have been duly authorized, and when issued and delivered pursuant to the terms of this Indenture in payment of the Change of Control Repurchase Price in respect of Securities, will be validly issued, fully paid and non assessable and, to the best of such counsel’s knowledge, free from preemptive rights under the Company’s certificate of incorporation, bylaws or any material contract; and (B) the conditions in clause (i) above have been satisfied in all material respects.

If the foregoing conditions are not satisfied with respect to a Holder or Holders prior to 5:00 p.m. (New York City time) on the Business Day immediately preceding the Change of Control Repurchase Date, and the Company has elected to repurchase the Securities pursuant to this Section 11.04, in whole or in part, through the issuance of shares of Applicable Stock, the Company shall pay the entire Change of Control Repurchase Price of the Securities of such Holder or Holders in cash. Upon determination of the actual number of shares of Applicable Stock to be issued upon repurchase of Securities, the Company shall be required to disseminate a press release through a public medium as is customary for such a press release.

Section 11.05. Effect Of Repurchase Notice. Upon receipt by the Paying Agent of the Optional Repurchase Notice specified in Section 11.02(b) or the Change of Control Repurchase Notice specified in Section 11.03(c) (Optional Repurchase Notices and Change of Control Repurchase Notices, as applicable, being referred to herein as “Repurchase Notices”), the Holder of the Security in respect of which such Repurchase Notice was given shall (unless such Repurchase Notice is withdrawn as specified in the following two paragraphs) thereafter be entitled to receive solely the Optional Repurchase Price or the Change of Control Repurchase Price, as applicable (the Optional Repurchase Price and the Change of Control Repurchase Price, as applicable, being referred to herein as the “Repurchase Price”), with respect to such Security. Such Repurchase Price shall be paid to such Holder, subject to prior receipt of funds by

the Paying Agent, promptly following the later of (x) the Optional Repurchase Date or the Change of Control Repurchase Date, as applicable (the Optional Repurchase Date and the Change of Control Repurchase Date, as applicable, being referred to herein as the “Repurchase Date”), with respect to such Security (provided the conditions in 11.02(b) or 11.03(c), as applicable, have been satisfied) and (y) the time of delivery of such Security to the Paying Agent by the Holder thereof in the manner required by Section 11.02(b) or 11.03(c), as applicable, provided, however, that should any portion of the Repurchase Price be payable in shares of Applicable Stock, the Company will deliver such shares directly to the Holders in accordance with the share delivery instructions set forth in the Repurchase Notice. Securities in respect of which a Repurchase Notice has been given may not be converted pursuant to Article 13 hereof on or after the date of the delivery of such Repurchase Notice, except if the Repurchase Notice, if applicable, has first been validly withdrawn as specified in the following two paragraphs.

A Repurchase Notice may be withdrawn by means of a written notice of withdrawal delivered to the office of the Paying Agent in accordance with the procedures set forth in the Change of Control Company Notice at any time prior to the close of business on the Business Day prior to the Repurchase Date specifying:

(i) the certificate number of the Security in respect of which such notice of withdrawal is being submitted;

(ii) the Principal Amount of the Security with respect to which such notice of withdrawal is being submitted; and

(iii) the Principal Amount, if any, of such Security which remains subject to the original Repurchase Notice and which has been or will be delivered for repurchase by the Company.

There shall be no purchase of any Securities pursuant to Section 11.02 or 11.03 if there has occurred (prior to, on or after, as the case may be, the giving, by the Holders of such Securities, of the required Repurchase Notice) and is continuing an Event of Default (other than a default in the payment of the Repurchase Price with respect to such Securities). The Paying Agent will promptly return to the respective Holders of any Securities (x) with respect to which a Repurchase Notice has been withdrawn in compliance with this Indenture, or (y) held by it during the continuance of an Event of Default (other than a default in the payment of the Repurchase Price with respect to such Securities) in which case, upon such return, the Repurchase Notice with respect thereto shall be deemed to have been withdrawn.

Section 11.06. Deposit Of Repurchase Price. Prior to 10:00 a.m. (New York City time) on the Business Day following the Repurchase Date, the Company shall deposit with the Trustee or with the Paying Agent (or if the Company or a Subsidiary or an Affiliate of any of them is acting as the Paying Agent, shall segregate and hold in trust as provided herein) an amount of cash (in immediately available funds if deposited on such Business Day) sufficient to pay the portion of the aggregate Repurchase Price of all the Securities or portions thereof which are to be repurchased on such Repurchase Date that is to be paid in cash as set forth in the relevant notice of Change in Control in accordance with Section 11.04.

If the Paying Agent holds, in accordance with the terms hereof, at 10:00 a.m. (New York City time) on the Business Day immediately following the applicable Repurchase Date, cash sufficient to pay the portion of the Repurchase Price that is to be paid in cash of any Securities for which a Repurchase Notice has been tendered and not withdrawn pursuant to Section 11.05, then, immediately after such Repurchase Date, such Securities will cease to be outstanding, and the rights of the Holders in respect thereof shall terminate (other than the right to receive the Repurchase Price upon delivery of such Securities).

As soon as practicable on and after the Change of Control Repurchase Date, the Company shall deliver to each Holder entitled to receive shares of Applicable Stock, a certificate (other than in the case of Holders of Securities in book-entry form with the Depositary, which shares shall be delivered in accordance with the Depositary customary practices) for the number of full shares of Applicable Stock issuable in payment of the Change of Control Repurchase Price and cash in lieu of any fractional interests. The person in whose name the certificate for the shares of Applicable Stock is registered shall be treated as a holder of record of Applicable Stock on the Change of Control Repurchase Date. No payment or adjustment will be made for

dividends on the shares of Applicable Stock the record date for which occurred on or prior to the Change of Control Repurchase Date.

Section 11.07. Securities Repurchased or Redeemed In Part. Any Security which is to be repurchased or redeemed only in part shall be surrendered at the office of the Paying Agent (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or 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 which is not repurchased or redeemed.

Section 11.08. Covenant To Comply With Securities Laws Upon Repurchase or Redemption Of Securities. In connection with any offer to redeem or repurchase Securities under Section 11.01, 11.02 or 11.03 hereof (provided that such offer of redemption or repurchase constitutes an “issuer tender offer” for purposes of Rule 13e-4 (which term, as used herein, includes any successor provision thereto) under the Exchange Act at the time of such offer or purchase), and subject to any exemptions under applicable law, the Company shall (i) comply with Rule 13e-4 and Rule 14e-1 (or any successor provision) under the Exchange Act, (ii) file the related Schedule TO (or any successor schedule, form or report) under the Exchange Act, and (iii) otherwise comply with all Federal and state securities laws so as to permit the rights and obligations under Section 11.01, 11.02 or 11.03, as applicable, to be exercised in the time and in the manner specified in such Section.

To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Article 11, the Company’s compliance with such laws and regulations including the extension of the payment or notice periods contemplated by this Article, shall not in and of itself cause a breach of their obligations under this Article 11.

Section 11.09. Repayment To The Company. The Trustee and the Paying Agent shall return to the Company any cash that remains unclaimed, together with dividends, if any, thereon, held by them for the payment of the Redemption Price or Repurchase Price; provided, however, that to the extent that the aggregate amount of cash deposited by the Company exceeds the portion of the aggregate Redemption Price or Repurchase Price of the Securities or portions thereof which the Company is obligated to purchase in cash as of the Redemption Date or Repurchase Date then on the Business Day following the Redemption Date or Repurchase Date the Trustee or the Paying Agent, as the case may be, shall return any such excess to the Company.

ARTICLE 12

PAYMENTS OF LIQUIDATED DAMAGES AMOUNTS ON THE SECURITIES

Section 12.01. Payment Of Liquidated Damages Amounts; Interest Rights Preserved. (a) Accrued but unpaid Liquidated Damages Amounts, if any, on any Security that is payable, and is punctually paid or duly provided for, on any Liquidated Damages Payment Date shall be paid to the Person in whose name that Security is registered at the close of business on the Regular Record Date for such interest at the office or agency of the Company maintained for such purpose. Each installment of Liquidated Damages Amounts, if any on any Security shall be made by check mailed to the address of the Holder specified in the register of Securities, or, at the option of the Holder, at the Corporate Trust Office, in such lawful money of the United States of America as at the time of payment shall be legal tender for the payment of public and private debts; provided, however, that, with respect to any Holder of Securities with an aggregate principal amount in excess of $5,000,000, at the request of such Holder in writing to the Company, Liquidated Damages Amounts, if any on such Holder’s Securities shall be paid by wire transfer in immediately available funds in accordance with the written wire transfer instruction supplied by such Holder from time to time to the Trustee and Paying Agent (if different from the Trustee) at least two days prior to the applicable Regular Record Date. In the case of a permanent Global Security, interest payable on any Liquidated Damages Payment Date will be paid to the Depositary, with respect to that portion of such permanent Global Security held for its account by Cede & Co. for the purpose of permitting such

party to credit the interest received by it in respect of such permanent Global Security to the accounts of the beneficial owners thereof.

ARTICLE 13

CONVERSION

Section 13.01. Right To Convert. (a) Subject to and upon compliance with the provisions of this Indenture, each Holder shall have the right, at such Holder’s option, at any time following the Issue Date of the Securities hereunder through the close of business on the Final Maturity Date to convert the Principal Amount of any such Securities, or any portion of such Principal Amount which is $1,000 or an integral multiple thereof, at the Conversion Price then in effect.

(b) Notwithstanding the foregoing, a Security in respect of which a Holder has delivered a Repurchase Notice exercising such Holder’s option to require the Company to repurchase such Security may be converted only if such notice of exercise is withdrawn in accordance with Article 11 hereof prior to the close of business on the Business Day immediately preceding the Repurchase Date.

Section 13.02. Conversion Procedure. (a) Each Security shall be convertible at the office of the Conversion Agent into fully paid and nonassessable shares (calculated to the nearest 1/100th of a share) of Common Stock. The Security will be converted into shares of Common Stock at the Conversion Price therefor.

(b) In order to exercise the conversion privilege with respect to any Securities in certificated form, the Holder of any such Securities to be converted, in whole or in part, shall:

(i) complete and manually sign the conversion notice provided on the back of the Security (the “Conversion Notice”) and deliver such notice to a Conversion Agent;

(ii) surrender the Security to a Conversion Agent;

(iii) furnish appropriate endorsements and transfer documents, if required; and

(iv) pay any transfer or similar tax, if required.

The date on which the Holder satisfies all of the requirements set forth in (i) through (iv) above is the “Conversion Date.” Such notice shall also state the name or names (with address or addresses) in which the certificate or certificates for shares of Common Stock which shall be issuable on such conversion shall be issued. All such Securities surrendered for conversion shall, unless the shares 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 his duly authorized attorney.

In order to exercise the conversion privilege with respect to any interest in Securities in global form, the Holder must complete the appropriate instruction form for conversion pursuant to the Depositary’s book-entry conversion program, furnish appropriate endorsements and transfer documents if required by the Company or the Trustee or Conversion Agent, and pay the funds, if any, required by this Section 13.02 and any transfer taxes if required pursuant to Section 13.06.

(c) As promptly as practicable after satisfaction of the requirements for conversion set forth above (but in no event later than three Business Days after the Conversion Date), subject to compliance with any restrictions on transfer if shares issuable on conversion are to be issued in a name other than that of the Holder (as if such transfer were a transfer of the Securities (or portion thereof) so converted), the Company shall issue and shall deliver to such Holder, a certificate or certificates for the number of full shares of Common Stock issuable upon the conversion of such Securities or portion thereof in accordance with the provisions of this Article and a check or cash in respect of any fractional interest in respect of a share of Common Stock arising upon such conversion, as provided in Section 13.03. In case any Securities of 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 to him, new Securities in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Securities.

Each conversion shall be deemed to have been effected as to any such Securities (or portion thereof) on the date on which the requirements set forth above in this Section 13.02 have been satisfied as to such Securities (or portion thereof), and the person in whose name any certificate or certificates for shares of Common Stock shall be issuable upon such conversion shall be deemed to have become on said date the Holder of record of the shares represented thereby; provided, however, that in case of any such surrender on any date when the stock transfer books of the Company shall be closed, the person or persons in whose name the certificate or certificates for such shares are to be issued shall be deemed to have become the record Holder thereof for all purposes on the next day on which such stock transfer books are open, but such conversion shall be at the Conversion Price in effect on the date upon which such Securities shall be surrendered.

(d) Upon the conversion of an interest in Global Securities, the Trustee (or other Conversion Agent appointed by the Company) shall make a notation on such Global Securities 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.

(e) Each stock certificate representing Common Stock issued upon conversion of the Securities that are Restricted Securities shall bear the legend in substantially the form of Exhibit D hereto.

Section 13.03. Cash Payments In Lieu Of Fractional Shares. The Company will not issue fractional shares of Common Stock upon conversion of Securities. If multiple Securities shall be surrendered for conversion at one time by the same Holder, the number of full shares which 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 stock would be issuable upon the conversion of any Securities, the Company shall make payment therefor in cash equal to the fraction of a share of Common Stock otherwise issuable multiplied by the Current Market Price (as defined in Section 13.04(g)) to the Holder of Securities.

Section 13.04. Adjustment Of Conversion Price. The Conversion Price shall be adjusted from time to time by the Company as follows:

(a) In case the Company shall, at any time or from time to time while any of the Securities are outstanding, pay a dividend or make a distribution in shares of Common Stock to all holders of its outstanding shares of Common Stock, then the Conversion Price in effect at the opening of business on the date following the date fixed for the determination of stockholders entitled to receive such dividend or other distribution shall be adjusted by multiplying such Conversion Price by a fraction, (i) the numerator of which shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination, and (ii) the denominator of which shall be the sum of such number of shares and the total number of shares constituting such dividend or other distribution. Such reduction becomes effective immediately after the opening of business on the day following the date fixed for such determination. If any dividend or distribution of the type described in this Section 13.04(a) is declared but not so paid or made, the Conversion Price shall again be adjusted to the Conversion Price which would then be in effect if such dividend or distribution had not been declared.

(b) In case the Company shall, at any time or from time to time while any of the Securities are outstanding, issue to all holders of its outstanding shares of Common Stock rights or warrants entitling them (for a period of not more than 60 days after such issuance) to subscribe for or purchase shares of Common Stock (or securities convertible into or exchangeable or exercisable for Common Stock) at a price per share (or having a conversion, exchange or exercise price per share) less than the Sale Price of Common Stock on the Business Day immediately preceding the date of announcement of such issuance, the Conversion Price shall be adjusted so that the same shall equal the price determined by multiplying the

Conversion Price in effect at the opening of business on the date of such announcement by a fraction, (i) the numerator of which shall be the number of shares of Common Stock outstanding at the close of business on the date of announcement, plus the number of shares which the aggregate offering price of the total number of shares so offered would purchase at such Sale Price of Common Stock on the Business Day immediately preceding the date of announcement of such issuance (determined by multiplying such total number of shares so offered by the exercise price of such rights or warrants and dividing the product so obtained by such Sale Price), and (ii) the denominator of which shall be the number of shares of Common Stock outstanding at the close of business on the date of announcement plus the total number of additional shares of Common Stock offered for subscription or purchase or into which convertible, exchangeable or exercisable, securities so offered are convertible, exchangeable or exercisable.

Such adjustment shall become effective immediately after the opening of business on the day following the date of announcement of such issuance.

To the extent that shares of Common Stock (or securities convertible into or exchangeable or exercisable for shares of Common Stock) are not delivered pursuant to such rights or warrants, upon the expiration or termination of such rights or warrants, the Conversion Price shall be readjusted to the Conversion Price which would then be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of the delivery of only the number of shares of Common Stock (or securities convertible into or exchangeable or exercisable for shares of Common Stock) actually delivered. In the event that such rights or warrants are not so issued, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if the date fixed for the determination of stockholders entitled to receive such rights or warrants had not been fixed. In determining whether any rights or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than such Sale Price, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received for such rights or warrants and the value of such consideration, if other than cash, to be determined in good faith by the Board of Directors of the Company.

(c) In case the Company shall, at any time or from time to time while any of the Securities are outstanding, subdivide its outstanding shares of Common Stock into a greater number of shares of Common Stock, then the Conversion Price in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately reduced, and conversely, in case the Company shall, at any time or from time to time while any of the Securities are outstanding, combine its outstanding shares of Common Stock into a smaller number of shares of Common Stock, then the Conversion Price in effect at the opening of business on the day following the day upon which such combination becomes effective shall be proportionately increased. In each such case, the Conversion Price shall be adjusted by multiplying such Conversion Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such subdivision or combination and the denominator of which shall be the number of shares of Common Stock outstanding immediately after giving effect to such subdivision or combination. Such reduction or increase, as the case may be, shall become effective immediately after the opening of business on the day following the day upon which such subdivision or combination becomes effective.

(d) (i) In case the Company shall, at any time or from time to time while the Securities are outstanding, by dividend or otherwise, distribute to all holders of its Common Stock shares of any class of capital stock of the Company (other than any dividends or distributions to which Section 13.04(a) applies) or evidences of its indebtedness or assets (including securities, but excluding any rights or warrants referred to in Section 13.04(b), and excluding any dividend or distribution (x) paid exclusively in cash or (y) referred to in Section 13.04(a)) (any of the foregoing hereinafter in this Section 13.04(d)) called the “Distributed Securities”), then, in each such case, the Conversion Price shall be reduced so that the same shall be equal to the price determined by multiplying the Conversion Price in effect on the Record Date with respect to such distribution by a fraction:

(A) the numerator of which shall be the Current Market Price per share of the Common Stock on such Record Date less the fair market value (as determined by the Board of Directors, whose good faith determination shall be conclusive, and described in a resolution of the Board of Directors) on the Record

Date of the portion of the Distributed Securities so distributed applicable to one share of Common Stock, and

(B) the denominator of which shall be the Current Market Price per share of the Common Stock.

Such reduction shall become effective immediately prior to the opening of business on the day following the Record Date for such distribution. If the Board of Directors determines the fair market value of any distribution for purposes of this Section 13.04(d) by reference to the actual or when issued trading market for any securities, it must in doing so consider the prices in such market over the same period used in computing the Current Market Price of the Common Stock.

Each share of Common Stock issued upon conversion of securities pursuant to this Article 13 shall be entitled to receive the appropriate number of common stock or preferred stock purchase rights, if any, as may be provided by the terms of any stockholder rights plan adopted by the Company (notwithstanding the occurrence of an event causing such rights to separate from the Common Stock at or prior to the time of conversion). Any distribution of rights or warrants pursuant to a stockholder rights plan complying with the requirements set forth in the immediately preceding sentence of this paragraph shall not constitute a distribution of rights or warrants for the purposes of Section 13.04(b) or this Section 13.04(d).

(ii) For the purposes of this Section 13.04(d), rights or warrants distributed by the Company to all holders of its Common Stock entitling them to subscribe for or purchase shares of the Company’s capital stock (either initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or events (“Trigger Event”): (A) are deemed to be transferred with such shares of Common Stock; (B) are not exercisable; and (C) are also issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this Section 13.04(d) (and no adjustment to the Conversion Price under this Section 13.04(d) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights and warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Price shall be made under this Section 13.04(d). If any such right or warrant, including any such existing rights or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and record date with respect to new rights or warrants with such rights (and a termination or expiration of the existing rights or warrants without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Price under this Section 13.04(d) was made, (1) in the case of any such rights or warrants which shall all have been redeemed or repurchased without exercise by any Holders thereof, the Conversion Price shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder of Common Stock with respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to all applicable holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights or warrants which shall have expired or been terminated without exercise by any holders thereof, the Conversion Price shall be readjusted as if such rights and warrants had not been issued.

(iii) For purposes of this Section 13.04(d) and Sections 13.04(a), 13.04(b), and 13.04(c), any dividend or distribution to which this Section 13.04(d) is applicable that also includes (x) shares of Common Stock, (y) rights or warrants to subscribe for or purchase shares of Common Stock or securities convertible into or exercisable or exchangeable for Common Stock to which Section 13.04(b) applies (or any combination thereof), or (z) a subdivision or combination of shares of Common Stock to which Section 13.04(c) applies or shall be deemed instead to be:

(A) a dividend or distribution of the evidences of indebtedness, assets, shares of capital stock, rights or warrants, other than such shares of Common Stock, such rights or warrants or securities convertible into or exercisable or exchangeable for Common Stock or such subdivision or combination to which Sections

13.04(a), 13.04(b), and 13.04(c) apply, respectively (and any Conversion Price reduction required by this Section 13.04(d) with respect to such dividend or distribution shall then be made), immediately followed by,

(B) a dividend or distribution of such shares of Common Stock, such rights or warrants or securities convertible into or exercisable or exchangeable for Common Stock or such subdivision or combination (and any further Conversion Price reduction required by Section 13.04(a), 13.04(b), and 13.04(c) with respect to such dividend or distribution shall then be made), except:

(1) the Record Date of such dividend or distribution shall be substituted as (x) “the date fixed for the determination of stockholders entitled to receive such dividend or other distribution,” and “the date fixed for such determination” within the meaning of Section 13.04(a), (y) “the date fixed for the determination of stockholders entitled to receive such rights or warrants,” within the meaning of Section 13.04(b) and (z) “the day upon which such subdivision becomes effective” and “the day upon which such combination becomes effective” within the meaning of Section 13.04(c); and

(2) any shares of Common Stock included in such dividend or distribution shall not be deemed “outstanding at the close of business on the date fixed for such determination” within the meaning of Section 13.04(a) and any reduction or increase in the number of shares of Common Stock resulting from such subdivision or combination shall be disregarded in connection with such dividend or distribution.

(e) In case the Company shall, at any time or from time to time while any of the Securities are outstanding, by dividend or otherwise, distribute to all holders of its shares of Common Stock, cash (excluding any cash that is distributed upon a merger or consolidation to which Section 13.05 applies or as part of a distribution referred to in Section 13.04(d)) (on a per-share basis, the “Cash Dividend Amount”), then, and in each case, immediately after the close of business on such date, the Conversion Price shall be adjusted so that the same shall equal the rate determined by multiplying the Conversion Price in effect immediately prior to the close of business of such Record Date by a fraction:

(A) the numerator of which shall be equal to the Current Market Price on the Record Date less the Cash Dividend Amount; and

(B) the denominator of which shall be equal to the Current Market Price on such date.

(f) In case a tender offer made by the Company or any of its subsidiaries for all or any portion of the Common Stock shall expire and such tender offer (as amended upon the expiration thereof) shall require the payment to stockholders (based on the acceptance (up to any maximum specified in the terms of the tender offer) of Purchased Shares (as defined below)) of an aggregate consideration having a fair market value (as determined by the Board of Directors, whose good faith determination shall be conclusive and described in a resolution of the Board of Directors) that combined together with the aggregate of the cash plus the fair market value (as determined by the Board of Directors, whose good faith determination shall be conclusive and described in a resolution of the Board of Directors), as of the expiration of such tender offer, of any other consideration payable in respect of any other tender offers, by the Company or any of its subsidiaries for all or any portion of the Common Stock expiring within the 12 months preceding the expiration of such tender offer and in respect of which no adjustment pursuant to this Section 13.04(f) has been made, exceeds 10% of the product of the Sale Price of the Common Stock as of the last time (the “Expiration Time”) tenders could have been made pursuant to such tender offer (as it may be amended), times the number of shares of Common Stock outstanding (including any tendered shares) at the Expiration Time, then, and in each such case, immediately prior to the opening of business on the day after the date of the Expiration Time, the Conversion Price shall be adjusted so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to close of business on the date of the Expiration Time by a fraction (A) the numerator of which shall be the product of (1) the number of shares of Common Stock outstanding (including any tendered shares) at the Expiration Time and (2) the Current Market Price of the Common Stock on the Trading Day next succeeding the Expiration Time, and (B) the denominator of which shall be the sum of (x) the fair market value (determined as aforesaid) of the aggregate consideration payable to stockholders based on the acceptance (up to any maximum specified in

the terms of the tender offer) of all shares validly tendered and not withdrawn as of the Expiration Time (the shares deemed so accepted, up to any such maximum, being referred to as the “Purchased Shares”) and (y) the product of the number of shares of Common Stock outstanding (less any Purchased Shares) at the Expiration Time and the Current Market Price of the Common Stock on the Trading Day next succeeding the Expiration Time. Such reduction (if any) shall become effective immediately prior to the opening of business on the Business Day following the Expiration Time. In the event that the Company is obligated to purchase shares pursuant to any such tender offer, but the Company is permanently prevented by applicable law from effecting any such purchases or all such purchases are rescinded, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such tender offer had not been made. If the application of this Section 13.04(f) to any tender offer would result in an increase in the Conversion Price, no adjustment shall be made for such tender offer under this Section 13.04(f).

(g) For purposes of this Section 13.04, the following terms shall have the meaning indicated:

(1) “Current Market Price” on any date means the average of the Sales Prices per share of Common Stock for the 10 consecutive Trading Days immediately preceding the day before the record date (or, if earlier, the Ex-Dividend date) with respect to any distribution, issuance or other event requiring such computation.

(2) “fair market value” shall mean the amount which a willing buyer would pay a willing seller in an arm’s length transaction.

(3) “Record Date” shall mean, with respect to any dividend, distribution or other transaction or event in which the holders of Common Stock have the right to receive any cash, securities or other property or in which the Common Stock (or other applicable security) is exchanged for or converted into any combination of cash, securities or other property, the date fixed for determination of stockholders entitled to receive such cash, securities or other property (whether such date is fixed by the Board of Directors or by statute, contract or otherwise).

(h) The Company may make such decreases in the Conversion Price, in addition to any adjustments required by Sections 13.04(a), 13.04(b), 13.04(c), 13.04(d), 13.04(e) or 13.04(f), as the Board of Directors considers to be advisable to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock resulting from any dividend or distribution of stock (or rights to acquire stock) or from any event treated as such for income tax purposes.

(i) To the extent permitted by applicable law, the Company from time to time may decrease the Conversion Price by any amount for any period of time if the period is at least 20 days, the decrease is irrevocable during the period and the Board of Directors shall have made a determination that such decrease would be in the best interests of the Company, which determination shall be conclusive. Whenever the Conversion Price is decreased pursuant to the preceding sentence, the Company shall mail to Holders of record of the Securities a notice of the decrease at least 15 days prior to the date the decreased Conversion Price takes effect, and such notice shall state the decreased Conversion Price and the period during which it will be in effect.

(j) No adjustment in the Conversion Price shall be required unless such adjustment would require an increase or decrease of at least 1% in such price; provided, however, that any adjustments which by reason of this Section 13.04(j) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Article 13 shall be made by the Company and shall be made to the nearest cent or to the nearest one-hundredth of a share, as the case may be. No adjustment need be made for rights to purchase Common Stock pursuant to a Company plan for reinvestment of dividends or interest. To the extent the Securities become convertible into cash, assets, property or securities (other than capital stock of the Company), no adjustment need be made thereafter as to the cash, assets, property or such securities. Interest will not accrue on the cash.

(k) Whenever the Conversion Price is adjusted as herein provided, the Company shall promptly file with the Trustee and any Conversion Agent an Officers’ Certificate setting forth the Conversion Price after

such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Price and may assume without inquiry that the last Conversion Price of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Price setting forth the adjusted Conversion Price and the date on which each adjustment becomes effective and shall mail such notice of such adjustment of the Conversion Price to each Holder of Securities at such Holder’s last address appearing on the list of Security holders provided for in Section 3.05 of this Indenture, within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

(l) In any case in which this Section 13.04 provides that an adjustment shall become effective immediately after a Record Date for an event, the Company may defer until the occurrence of such event (i) issuing to the Holder of any Securities converted after such Record Date and before the occurrence of such event the additional shares of Common Stock issuable upon such conversion by reason of the adjustment required by such event over and above the Common Stock issuable upon such conversion before giving effect to such adjustment and (ii) paying to such Holder any amount in cash in lieu of any fraction pursuant to Section 13.03.

(m) For purposes of this Section 13.04, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock 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.

(n) No adjustment to the Conversion Price shall be made pursuant to this Section 13.04 if the Holders of the Securities may participate in the transaction that would otherwise give rise to an adjustment pursuant to this Section 13.04.

Section 13.05. Effect Of Reclassification, Consolidation, Merger Or Sale. If any of the following events occur, namely:

(i) any reclassification or change of shares of Common Stock issuable upon conversion of the Securities (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 subdivision or combination, or any other change for which an adjustment is provided in Section 13.04(c));

(ii) any consolidation or merger or combination to which the Company is a party other than a merger in which the Company is the continuing corporation and which does not result in any reclassification of, or change (other than 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 subdivision or combination) in outstanding shares of Common Stock; or

(iii) any sale or conveyance of all or substantially all of the properties and assets of the Company to any other person as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Common Stock

then the Company or the successor or purchasing person, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the Trust Indenture Act of 1939 as in force at the date of execution of such supplemental indenture) providing that such Securities shall be convertible into the kind and amount of shares of stock, securities or other property or assets (including cash) receivable upon such reclassification, change, consolidation, merger, combination, sale or conveyance by a holder of a number of shares of Common Stock issuable upon conversion of such Securities (assuming, for such purposes, a sufficient number of authorized shares of Common Stock available to convert all such Securities) immediately prior to such reclassification, change, consolidation, merger, combination, sale or conveyance, assuming such holder of Common Stock did not exercise his rights of election, if any, as to the kind or amount of securities, cash or other property receivable upon such reclassification, change,

consolidation, merger, combination, sale or conveyance ( provided that, if the kind or amount of stock, securities or other property or assets (including cash) receivable upon such reclassification, change, consolidation, merger, combination, sale or conveyance is not the same for each share of Common Stock in respect of which such rights of election shall not have been exercised (“nonelecting share”), then for the purposes of this Section 13.05, the kind and amount of stock, securities or other property or assets (including cash) receivable upon such reclassification, change, consolidation, merger, combination, sale or conveyance for each non-electing share shall be deemed to be the kind and amount so receivable per share by a plurality of the non-electing shares). Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article 13. If, in the case of any such reclassification, change, consolidation, merger, combination, sale or conveyance, the stock, securities or other property or assets (including cash) receivable thereupon by a holder of Common Stock includes shares of stock, securities or other property or assets (including cash) of a corporation other than the successor or purchasing corporation, as the case may be, in such reclassification, change, consolidation, merger, combination, sale or conveyance, then such supplemental indenture shall also be executed by such other corporation and shall contain such additional provisions to protect the interests of the Holders of the Securities as the Board of Directors shall reasonably consider necessary by reason of the foregoing.

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 shall similarly apply to successive reclassifications, changes, consolidations, mergers, combinations, sales and conveyances. If this Section 13.05 applies to any event or occurrence, Section 13.04 shall not apply.

Section 13.06. Taxes On Shares Issued. The issue of stock certificates on conversions of Securities shall be made without charge to the converting Holder for any documentary, transfer, stamp or any similar tax in respect of the issue thereof, and the Company shall pay any and all documentary, stamp or similar issue or transfer taxes that may be payable in respect of the issue or delivery of shares of Common Stock on conversion of Securities pursuant hereto. The Company shall not, however, be required to pay any such tax which may be payable in respect of any transfer involved in the issue and delivery of stock in any name other than that of the Holder of any Securities converted, and the Company shall not be required to issue or deliver any such stock certificate unless and until the person or persons requesting the issue thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid.

Section 13.07. Reservation Of Shares; Shares To Be Fully Paid; Compliance With Governmental Requirements; Listing Of Common Stock. The Company shall provide, free from preemptive rights, out of its authorized but unissued shares, sufficient shares of Common Stock to provide for the conversion of the Securities from time to time as such Securities are presented for conversion (assuming that, at the time of the computation of such number of shares or securities, all such Securities would be held by a single Holder).

Before taking any action which would cause an adjustment reducing the Conversion Price below the then par value, if any, of the shares of Common Stock issuable upon conversion of the Securities, the Company will take all corporate action which may, in the opinion of its counsel, be necessary in order that the Company may validly and legally issue shares of such Common Stock at such adjusted Conversion Price.

The Company covenants that all shares of Common Stock which may be issued upon conversion of Securities shall be newly issued shares, shall be duly authorized, validly issued, fully paid and non-assessable and shall be free from preemptive rights and free from any lien or adverse claim.

The Company shall use its reasonable efforts to 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 13.08. Responsibility Of Trustee. The Trustee and any other Conversion Agent shall not at any time be under any duty or responsibility to any Holder of Securities to determine the Conversion Price or whether any facts exist which may require any adjustment of the Conversion Price, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other 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 securities or property, which may at any time be issued or delivered upon the conversion of any Securities; and the Trustee and any other 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. Without limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 13.05 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Holders upon the conversion of their Securities after any event referred to in such Section 13.05 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 6.01, may accept as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officers’ Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto.

Section 13.09. Notice To Holders Prior To Certain Actions. In case,

(a) the Company shall declare a dividend (or any other distribution) on its Common Stock that would require an adjustment in the Conversion Price pursuant to Section 13.04; or

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

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

(d) of the voluntary or involuntary dissolution, liquidation or winding up of the Company or any of its significant subsidiaries;

then, in each case, the Company shall cause to be filed with the Trustee and the Conversion Agent and to be mailed to each Holder of Securities at such Holder’s address appearing on the list of Security holders provided for in Section 3.05 of this Indenture, as promptly as practicable but in any event at least 15 days prior to the applicable date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution or rights or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution or rights are to be determined, or (y) the date on which such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding up is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such dividend, distribution, reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding up.

Section 13.10. Company Determination Final. Any determination that the Company or the Board of Directors must make pursuant to this Article 13 shall be conclusive if made in good faith and in accordance

with the provisions of this Article, absent manifest error, and set forth in a Board Resolution.

This instrument may be executed in any number of counterparts, each of which so executed shall be deemed to be an original, but all such counterparts shall together constitute but one and the same instrument.
