TRANSFER AGENT, AS APPLICABLE) SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS THE TRANSFER AGENT OR 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

(3) IT WILL DELIVER TO EACH PERSON TO WHOM THE SHARES OF COMMON STOCK EVIDENCED HEREBY ARE TRANSFERRED (OTHER THAN A TRANSFER PURSUANT TO CLAUSE 1(D) ABOVE) A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND.

THIS LEGEND WILL BE REMOVED UPON THE EARLIER OF THE TRANSFER OF THE SHARES OF COMMON STOCK EVIDENCED HEREBY PURSUANT TO CLAUSE 1(D) ABOVE OR THE EXPIRATION OF TWO YEARS FROM THE ORIGINAL ISSUANCE OF THE NOTE UPON THE CONVERSION OF WHICH THE SHARES OF COMMON STOCK EVIDENCED HEREBY WAS ISSUED. AS USED HEREIN, THE TERMS “UNITED STATES” AND “U.S. PERSON” HAVE THE MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT.

Each Security and each stock certificate representing shares of the Common Stock issued upon conversion of any Security (other than a stock certificate representing shares of the Common Stock issued upon conversion of a Security that previously has been sold pursuant to a registration statement that has been declared effective under the Securities Act and which continues to be effective at the time of such sale) shall bear the applicable Restricted Securities Legend set forth in Section 2.3(a)(i) or 2.3(a)(ii), as the case may be, until the earlier of:

(1) the date which is two years after the original issuance date of such Security; and

(2) the date such Security has, or such shares of the Common Stock have been sold pursuant to a registration statement that has been declared effective under the Securities Act (and which continues to be effective at the time of such sale).

The Holder must give notice thereof to the Trustee and any transfer agent for the Common Stock, as applicable.

Notwithstanding the foregoing, the Restricted Securities Legend may be removed from any Security or any stock certificate representing shares of the Common Stock issued upon conversion of any Security if there is delivered to the Company such satisfactory evidence, which may include an opinion of independent counsel, as may be reasonably required by the Company, that neither such legend nor the restrictions on transfer set forth therein are required to ensure that transfers of such Security or shares of the Common Stock issued upon conversion of Securities, as the case may be, will not violate the registration requirements of the Securities Act or the qualification requirements under any state securities laws. Upon provision of such satisfactory evidence, at the written direction of the Company, (i) in the case of a Security, the Trustee shall authenticate and deliver in exchange for such Security another

Security or Securities having an equal aggregate principal amount that does not bear such legend or (ii) in the case of a stock certificate representing shares of the Common Stock, the transfer agent for the Common Stock shall authenticate and deliver in exchange for the stock certificate or stock certificates representing such shares of Common Stock bearing such legend, one or more new stock certificates representing a like aggregate number of shares of Common Stock that do not bear such legend. If the Restricted Securities Legend has been removed from a Security or stock certificates representing shares of the Common Stock issued upon conversion of any Security as provided above, no other Security issued in exchange for all or any part of such Security or stock certificates representing shares of the Common Stock issued upon conversion of such Security shall bear such legend, unless the Company has reasonable cause to believe that such other Security is a “restricted security” (or such shares of Common Stock are “restricted securities”) within the meaning of Rule 144 and instructs the Trustee in writing to cause a Restricted Securities Legend to appear thereon.

Any Security (or Security issued in exchange or substitution therefor) as to which such restrictions on transfer shall have expired in accordance with their terms or as to which the conditions for removal of the Restricted Securities Legend set forth in Section 2.3(a)(i) as set forth therein have been satisfied may, upon surrender of such Security for exchange to the Registrar in accordance with the provisions of Section 2.7, be exchanged for a new Security or Securities, of like tenor and aggregate principal amount, which shall not bear the Restricted Securities Legend required by Section 2.3(a)(i).

Any stock certificate representing shares of the Common Stock issued upon conversion of any Security as to which such restrictions on transfer shall have expired in accordance with their terms or as to which the conditions for removal of the Restricted Securities Legend set forth in Section 2.3(a)(ii) as set forth therein have been satisfied may, upon surrender of the stock certificates representing such shares of Common Stock for exchange in accordance with the procedures of the transfer agent for the Common Stock, be exchanged for a new stock certificate or stock certificates representing a like aggregate number of shares of Common Stock, which shall not bear the Restricted Securities Legend required by Section 2.3(a)(ii).

THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE INDENTURE REFERRED TO HEREIN. THIS GLOBAL SECURITY MAY NOT BE EXCHANGED OR TRANSFERRED, IN WHOLE OR IN PART, FOR A SECURITY REGISTERED IN THE NAME OF ANY PERSON OTHER THAN DTC OR A NOMINEE THEREOF, EXCEPT IN THE LIMITED CIRCUMSTANCES SET FORTH IN THE INDENTURE. BENEFICIAL INTERESTS IN THIS GLOBAL SECURITY MAY NOT BE TRANSFERRED EXCEPT IN ACCORDANCE WITH THE INDENTURE.

Physical Securities, in addition to the legend set forth in Section 2.3(a)(i), will also bear a legend substantially in the following form:

THIS SECURITY WILL NOT BE ACCEPTED IN EXCHANGE FOR A BENEFICIAL INTEREST IN A GLOBAL SECURITY UNLESS THE HOLDER OF THIS SECURITY, SUBSEQUENT TO SUCH EXCHANGE, WILL HOLD NO DEBENTURES.

Two Officers of the Company shall execute the Securities on behalf of the Company by manual or facsimile signature. If an Officer of the Company whose signature is on a Security no longer holds that office at the time the Security is authenticated, the Security shall be valid nevertheless.

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, and the Trustee in accordance with such Company Order shall authenticate and deliver such Securities as in this Indenture provided and not otherwise.

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 or on behalf of 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.

The Trustee may appoint an authenticating agent or agents reasonably acceptable to the Company with respect to the Securities. Unless limited by the terms of such appointment, an authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent.

The Company shall maintain an office or agency where Securities may be presented for registration of transfer or for exchange (the “Registrar”) and an office or agency where Securities may be presented for payment (the “Paying Agent”). The Registrar shall keep a register of the Securities (the “Register”) and of their transfer and exchange. The Company may appoint one or more co-Registrars and one or more additional Paying Agents for the Securities. The term “Paying Agent” includes any additional paying agent and the term “Registrar” includes any additional registrar. The Company may change any Paying Agent or Registrar without prior notice to any Holder.

The Company will 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:

(1) hold all sums held by it for the payment of the principal of and premium, if any, or interest (including Additional Amounts, if any) on Securities in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as provided in this Indenture;

(2) give the Trustee notice of any Default by the Company in the making of any payment of principal and premium, if any, or interest (including Additional Amounts, if any); and

(3) at any time during the continuance of any such Default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent.

The Company shall give prompt written notice to the Trustee of the name and address of any Agent who is not a party to this Indenture. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Company or any Affiliate of the Company may act as Paying Agent or Registrar; provided, however, that none of the Company, its subsidiaries or the Affiliates of the foregoing shall act:

(i) as Paying Agent in connection with redemptions, offers to purchase and discharges, except as otherwise specified in this Indenture, and

(ii) as Paying Agent or Registrar if a Default or Event of Default has occurred and is continuing.

The Company hereby initially appoints the Trustee as Registrar and Paying Agent for the Securities.

Not later than 11:00 a.m. (New York City time) on each due date of the principal, premium, if any, and interest (including Additional Amounts, if any) on any Securities, the Company shall deposit with one or more Paying Agents money in immediately available funds in an aggregate amount sufficient to pay the principal, premium, if any, and interest (including Additional Amounts, if any) due on such date. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Company) shall have no further liability for the money so paid over to the Trustee.

If the Company shall act as a Paying Agent, it shall, prior to or on each due date of the principal of and premium, if any, or interest (including Additional Amounts, if any) on any of the Securities, segregate and hold in trust for the benefit of the Holders a sum sufficient with monies held by all other Paying Agents, to pay the principal and premium, if any, or interest (including Additional Amounts, if any) so becoming due until such sums shall be paid to such Persons or otherwise disposed of as provided in this Indenture, and shall promptly notify the Trustee of its action or failure to act.

The Securities are issuable only in registered form. A Holder may transfer a Security only by written application to the Registrar stating the name of the proposed transferee and otherwise complying with the terms of this Indenture. No such transfer shall be effected until, and such transferee shall succeed to the rights of a Holder only upon, final acceptance and registration of the transfer by the Registrar in the Register. Furthermore, any Holder of a Global Security shall, by acceptance of such Global Security, agree that transfers of beneficial interests in such Global Security may be effected only through a book-entry system maintained by the Holder of such Global Security (or its agent) and that ownership of a beneficial interest in the Global Security shall be required to be reflected in a book-entry. Notwithstanding the foregoing, in the case of a Restricted Security, a beneficial interest in a Global Security being transferred in reliance on an exemption from the registration requirements of the Securities Act other than in accordance with Rule 144 or Rule 144A may only be transferred for a Physical Security.

When Securities are presented to the Registrar with a request to register the transfer or to exchange them for an equal aggregate principal amount of Securities of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested if its requirements for such transactions are met (including that such Securities are duly endorsed or accompanied by a written instrument of transfer duly executed by the Holder thereof or by an attorney who is authorized in writing

to act on behalf of the Holder). Subject to Section 2.4, to permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Securities at the Registrar’s request. No service charge shall be made for any registration of transfer or exchange or redemption of the Securities, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or other similar governmental charge payable upon exchanges pursuant to Section 2.14, 7.5 or 10.6).

Neither the Company nor the Registrar shall be required to exchange or register a transfer of any Securities:

(1) for a period of 15 Business Days prior to the day of any selection of Securities for redemption under Article 10;

(2) so selected for redemption or, if a portion of any Security is selected for redemption, the portion thereof selected for redemption; or

(3) surrendered for conversion or, if a portion of any Security is surrendered for conversion, the portion thereof surrendered for conversion.

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 such 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 such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing contained herein shall prevent the Company, the Trustee or any agent of the Company or Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and the Agent Members, the operation of customary practices governing the exercise of the rights of a Holder of any Security.

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

(c) A Global Security may not be transferred, in whole or in part, to any Person other than the Depositary (or a nominee thereof), and no such transfer to any such other Person may be registered. Beneficial interests in a Global Security may be transferred in accordance with the rules and procedures of the Depositary and the provisions of Section 2.9.

(i) the Depositary notifies the Company in writing that it is no longer willing or able to continue to act as Depositary for the Global Securities, or the Depositary ceases to be a “clearing agency” registered under the Exchange Act and a successor depositary for the Global Securities is not appointed by the Company within 90 days of such notice or cessation;

(ii) the Company, at its option, notifies the Trustee in writing that it elects to cause the issuance of the Physical Securities under this Indenture in exchange for all or any part of the Securities represented by a Global Security or Global Securities; or

(iii) an Event of Default has occurred and is continuing and the Registrar has received a request from the Depositary for the issuance of Physical Securities in exchange for such Global Security or Global Securities;

the Depositary shall surrender such Global Security or Global Securities to the Trustee for cancellation and the Company shall execute, and the Trustee, upon receipt of an Officers’ Certificate and Company Order for the authentication and delivery of Securities, shall authenticate and deliver in exchange for such Global Security or Global Securities, Physical Securities in an aggregate principal amount equal to the aggregate principal amount of such Global Security or Global Securities. Such Physical Securities shall be registered in such names as the Depositary shall identify in writing as the beneficial owners of the Securities represented by such Global Security or Global Securities (or any nominee thereof).

(e) Notwithstanding the foregoing, in connection with any transfer of beneficial interests in a Global Security to the beneficial owners thereof pursuant to Section 2.8(d), the Registrar shall reflect on its books and records the date and a decrease in the principal amount of such Global Security in an amount equal to the principal amount of the beneficial interests in such Global Security to be transferred.

Unless a Security is (i) transferred after the time period referred to in Rule 144(k) under the Securities Act or (ii) sold pursuant to a registration statement that has been declared effective under the Securities Act (and which continues to be effective at the time of such sale), the following provisions shall apply to any sale, pledge or other transfer of Securities:

The following provisions shall apply with respect to the registration of any proposed transfer of Securities to a QIB:

(i) If the Securities to be transferred consist of a beneficial interest in the Global Securities, the transfer of such interest may be effected only through the book-entry systems maintained by the Depositary.

(ii) If the Securities to be transferred consist of Physical Securities, the 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 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 Registrar in writing that:

In addition, the Registrar shall reflect on its books and records the date and an increase in the principal amount of the Global Securities in an amount equal to the aggregate principal amount of the Physical Securities to be transferred, and the Trustee shall cancel the Physical Securities so transferred.

In the event that Global Securities are exchanged for Securities in definitive registered form pursuant to Section 2.8 prior to the effectiveness of a Shelf Registration Statement with respect to such Securities, such Securities may be exchanged only in accordance with the provisions of clause (a) above (including the certification requirements intended to ensure that such transfers comply with Rule 144A) and such other procedures as may from time to time be adopted by the Company.

By its acceptance of any Security bearing the Restricted Securities Legend, each Holder of such a Security acknowledges the restrictions on transfer of such Security set forth in this Indenture and agrees that it will transfer such Security only as provided in this Indenture. The Registrar shall not register a transfer of any Security unless such transfer complies with the restrictions on transfer of such Security set forth in this Indenture. The Registrar shall be entitled to receive and rely on written instructions from the Company verifying that such transfer complies with such restrictions on transfer. In connection with any transfer of Securities, each Holder agrees by its acceptance of the Securities to furnish the Registrar or the Company such certifications, legal opinions or other information as either of them may reasonably require to confirm that such transfer is being made pursuant to an exemption from, or a transaction not subject to, the registration requirements of the Securities Act; provided that the Registrar shall not be required to determine (but may rely on a determination made by the Company with respect to) the sufficiency of any such certifications, legal opinions or other information.

The Registrar shall retain copies of all certifications, letters, notices and other written communications received pursuant to Section 2.8 hereof or this Section 2.9. 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 Registrar.

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders and shall otherwise comply with Section 312(a) of the TIA. If the Trustee is not the Registrar, the Company shall furnish to the Trustee prior to or on each Interest Payment Date and at such other times as the Trustee may request in writing a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders relating to such Interest Payment Date or request, as the case may be.

The Company, the Trustee and any agent of the Company or the Trustee may treat the Holder as the owner of such Security for the purpose of receiving payment of principal of and premium, if any, and interest (including Additional Amounts, if any) on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and notwithstanding any notice of ownership or writing thereon, or any notice of previous loss or theft or other interest therein.

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.

(1) evidence to their satisfaction of the destruction, loss or theft of any Security; and

(2) such security or indemnity as may be required by 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, upon request, 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, but subject to any conversion rights, may, instead of issuing a new Security, pay such Security, upon satisfaction of the condition set forth in the preceding paragraph.

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 2.12 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 such new Security 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 2.12 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.

In determining whether the Holders of the requisite principal amount of Outstanding Securities are present at a meeting of Holders for quorum purposes or have given any request, demand, authorization, direction, notice, consent or waiver hereunder, Securities owned by the Company or any Affiliate of the Company shall be disregarded and deemed not to be Outstanding, except that, in determining whether the Trustee shall be protected in relying upon any such determination as to the presence of a quorum or upon any such request, demand, authorization, direction, notice, consent or waiver, only such Securities of which the Trustee has received written notice and are so owned shall be so disregarded.

Pending the preparation of Securities in definitive form, the Company may execute and the Trustee shall, upon written request of the Company, authenticate and deliver temporary Securities (printed or lithographed). Temporary Securities shall be issuable in any authorized denomination, and substantially in the form of the Securities in definitive form but with such omissions, insertions and variations as may be appropriate for temporary Securities, all as may be determined by the Company. Every such temporary Security shall be executed by the Company and authenticated by the Trustee upon the same conditions and in substantially the same manner, and with the same effect, as the Securities in definitive form. Without unreasonable delay, the Company will execute and deliver to the Trustee Securities in definitive form (other than in the case of Securities in global form) and thereupon any or all temporary Securities (other than any such Securities in global form) may be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant to Section 9.2 and the Trustee shall authenticate and deliver in exchange for such temporary Securities an equal aggregate principal amount of Securities in definitive form. Such exchange shall be made by the Company at its own expense and without any charge therefor. Until so exchanged, the temporary Securities shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Securities in definitive form authenticated and delivered hereunder.

All securities surrendered for payment, redemption, repurchase, conversion, registration of transfer or exchange shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee. All Securities so delivered shall be canceled promptly by the Trustee, and no Securities shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture. The Trustee shall destroy canceled Securities and, after such destruction, shall deliver a certificate of such destruction to the Company. 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 the same are delivered to the Trustee for cancellation.

The Company in issuing the Securities may use “CUSIP” numbers (if then generally in use), and the Trustee shall use CUSIP numbers in notices of redemption or exchange as a convenience to Holders; provided that any such notice shall state that no representation is made as to the correctness of

such numbers either as printed on the Securities or as contained in any such notice and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company shall promptly notify the Trustee of any change in the CUSIP numbers.

If the Company fails to make a payment of interest (including Additional Amounts, if any) on any Security when due and payable (“Defaulted Interest”), it shall pay such Defaulted Interest plus (to the extent lawful) any interest payable on the Defaulted Interest, in any lawful manner. It may elect to pay such Defaulted Interest, plus any such interest payable on it, to the Persons who are Holders of such Securities on which the interest is due on a subsequent Special Record Date. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each such Security. The Company shall fix any such Special Record Date and payment date for such payment. At least 15 days before any such Special Record Date, the Company shall mail to Holders affected thereby a notice that states the Special Record Date, the Interest Payment Date, and amount of such interest (and such Additional Amounts, if any) to be paid.

(1) the Company shall deliver to the Trustee for cancellation all Securities previously authenticated (other than any Securities which have been destroyed, lost or stolen and in lieu of, or in substitution for which, other Securities shall have been authenticated and delivered) and not previously canceled; or

(2) all the Securities not previously canceled or delivered to the Trustee for cancellation shall have become due and payable, or are by their terms to become due and payable within one year or are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption;

(3) the Company shall deposit with the Trustee, in trust, cash in U.S. Dollars and/or U.S. Government Obligations which through the payment of interest and principal in respect thereof, in accordance with their terms, will provide (and without reinvestment and assuming no tax liability will be imposed on such Trustee), not later than one day before the due date of any payment of money, an amount in cash, sufficient, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay principal of, premium, if any, or interest (including Additional Amounts, if any) on all of the Securities (other than any Securities which shall have been mutilated, destroyed, lost or stolen and in lieu of or in substitution for which other Securities shall have been authenticated and delivered) not previously canceled or delivered to the Trustee for cancellation, on the dates such payments of principal, premium, if any, or interest (including Additional Amounts, if any) are due to such date of Maturity or redemption, as the case may be; and

(4) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel to the effect that (x) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (y) since the date of execution of this Indenture, there has been a change in the applicable federal income tax law, in the case of either clause (x) or (y) to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders will not recognize income, gain or loss for federal income tax purposes as a result of such deposit and discharge and will be subject to federal income tax on the same amount and in the same manner and at the same times as would have been the case if such deposit and discharge had not occurred; and

if, in the case of either clause (3) or (4), the Company shall also pay or cause to be paid all other sums payable hereunder by the Company, then this Indenture shall cease to be of further effect (except as to: (i) remaining rights of registration of transfer, substitution and exchange and conversion of Securities; (ii) rights hereunder of Holders to receive payments of principal of and premium, if any, and interest (including Additional Amounts, if any) on, the Securities and the other rights, duties and obligations of Holders, as beneficiaries hereof with respect to the amounts, if any, so deposited with the Trustee; and (iii) the rights, obligations and immunities of the Trustee hereunder) and the Trustee, on demand of the Company accompanied by an Officers’ Certificate and an Opinion of Counsel and at the cost and expense of the Company, shall execute proper instruments acknowledging satisfaction of and discharging this Indenture; provided, however, that the Company shall reimburse the Trustee for all amounts due the Trustee under Section 5.8 and for any costs or expenses thereafter reasonably and properly incurred by the Trustee and to compensate the Trustee for any services thereafter reasonably and properly rendered by the Trustee in connection with this Indenture or the Securities.

Subject to Section 3.3, all monies deposited with the Trustee pursuant to Section 3.1 shall be held in trust and applied by it to the payment, notwithstanding the provisions of Article 14, either directly or through any Paying Agent (including the Company if acting as its own Paying Agent), to the Holders of the particular Securities for the payment or redemption of which such monies have been deposited with the Trustee, of all sums due and to become due thereon for principal, premium, if any, and interest (including Additional Amounts, if any). All monies deposited with the Trustee pursuant to Section 3.1 (and held by it or any Paying Agent) for the payment of Securities subsequently converted shall be returned to the Company upon the earlier of the request of the Company and the date on which there are no Securities outstanding.

The Trustee and the Paying Agent shall pay to the Company any money held by them for the payment of principal or premium, if any, or interest (including Additional Amounts, if any) that remains unclaimed for two years after the date upon which such payment shall have become due. After payment to the Company, Holders entitled to the money must look to the Company for payment as general creditors unless an applicable abandoned property law designates another Person, and all liability of the Trustee and such Paying Agent with respect to such money shall cease.

An “Event of Default” with respect to the Securities occurs when any of the following occurs (whatever the reason for such Event of Default and whether it shall be occasioned by the provisions of Article 14 or 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):

(a) the Company defaults in the payment of interest (including Additional Amounts, if any) on any of the Securities when it becomes due and payable and such default continues for a period of 30 days, whether or not such payment is prohibited by Article 14; or

(b) the Company defaults in the payment of the principal of or premium, if any, on any of the Securities when it becomes due and payable at Maturity, upon redemption or exercise of a Repurchase Right or otherwise, whether or not such payment is prohibited by Article 14; or

(c) the Company defaults in the payment of the principal of or premium, if any, on any of the Securities required to be purchased by the Company under Article 11 upon exercise of a Repurchase Right, whether or not such payment is prohibited by Article 14; or

(d) the Company defaults in the performance of, or the Company breaches any, covenant or agreement contained in this Indenture or the Securities (other than a default specified in clause (a), (b) or (c) above) and such default or breach continues for a period of 60 consecutive days after written notice of such breach or default shall have been given to the Company by the Trustee or to the Company and the Trustee by the Holders of 25% or more in aggregate principal amount of the Outstanding Securities; or

(e) the Company (i) defaults in the performance of any covenant or agreement contained in any agreements, indentures or instruments under which the Company has incurred Indebtedness of $15,000,000 or more in the aggregate (not including any amounts the Company may owe under reimbursement or similar obligations to banks, sureties or other entities which have issued letters of credit, surety bonds, performance bonds or other guarantees relating to the performance by the Company or its Subsidiaries of contractual obligations to customers, to the extent any demands made under any such reimbursement or similar obligation relate to a draw under the related letter of credit or other instrument which draw is being contested in good faith through appropriate proceedings) whether such indebtedness now exists or shall hereafter be created, and (ii) such default has caused the holders of such Indebtedness to declare such Indebtedness to be due and payable prior to its stated maturity and such Indebtedness has not been discharged in full or such acceleration has not been rescinded or annulled by the 30^th day after written notice of such default shall have been given to the Company by the Trustee or to the Company and the Trustee by Holders of 25% or more in aggregate principal amount of the Outstanding Securities; provided that if the default under the agreement, indenture or instrument is remedied or cured by the Company or waived by the holders of such Indebtedness before the entry of judgment in favor of the Trustee, then the Event of Default under this Indenture will be deemed likewise to have been remedied, cured or waived; or

(f) the entry by a court having jurisdiction in the premises of (i) a decree or order for relief in respect of the Company in an involuntary case or proceeding under any applicable U.S. federal or state bankruptcy, insolvency, reorganization or other similar law or (ii) a decree or order adjudging the Company a bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of the Company under any applicable U.S. federal or state law, or appointing a Custodian of the Company or of any substantial part of its property, or ordering the winding up or liquidation of its affairs, and the continuance of any such decree or order for relief or any such other decree or order unstayed and in effect for a period of 60 consecutive days; or

(g) the commencement by the Company of a voluntary case or proceeding under any applicable U.S. federal or state bankruptcy, insolvency, reorganization or other similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by the Company to the entry of a decree or order for relief in respect of the Company in an involuntary case or proceeding under any applicable U.S. federal or state bankruptcy, insolvency, reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or proceeding against the Company, or the filing by the Company of a petition or answer or consent seeking reorganization or relief under any applicable U.S. federal or state law, or the consent by the Company to the filing of such petition or to the appointment of or the taking possession by a Custodian of the Company or of any substantial part of its property, or the making by the Company of an assignment for the benefit of creditors, or the admission by the Company in writing of its inability to pay its debts generally as they become due, or the taking of corporate action by the Company expressly in furtherance of any such action.

If an Event of Default with respect to Outstanding Securities occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the Outstanding Securities, by written notice to the Company, may declare due and payable 100% of the principal amount of all Outstanding Securities plus any accrued and unpaid interest (including Additional Amounts, if any) to the date of payment. Upon a declaration of acceleration, such principal and accrued and unpaid interest (including Additional Amounts, if any) to the date of payment shall be immediately due and payable.

The Holders either (a) through notice to the Trustee of not less than a majority in aggregate principal amount of the Outstanding Securities, or (b) by the adoption of a resolution, at a meeting of Holders of the Outstanding Securities at which a quorum is present, by the Holders of at least a majority in aggregate principal amount of the Outstanding Securities represented at such meeting, may, on behalf of the Holders of all of the Securities, rescind and annul an acceleration and its consequences if:

(1) all existing Events of Default, other than the nonpayment of principal of or interest on the Securities which have become due solely because of the acceleration, have been remedied, cured or waived, and

(2) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction;

provided, however, that in the event such declaration of acceleration has been made based on the existence of an Event of Default under Section 4.1(e) and the default with respect to Indebtedness for money borrowed which gave rise to such Event of Default has been remedied, cured or waived, then, without any further action by the Holders, such declaration of acceleration shall be rescinded automatically and the consequences of such declaration shall be annulled. No such rescission or annulment shall affect any subsequent Default or impair any right consequent thereon.

If an Event of Default with respect to Outstanding Securities occurs and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of principal of or interest on the Securities or to enforce the performance of any provision of the Securities.

The Trustee may maintain a proceeding in which it may prosecute and enforce all rights of action and claims under this Indenture or the Securities, even if it does not possess any of the Securities or does not produce any of them in the proceeding.

The Holders, either (a) through the written consent of not less than a majority in aggregate principal amount of the Outstanding Securities, or (b) by the adoption of a resolution, at a meeting of Holders of the Outstanding Securities at which a quorum is present, by the Holders of at least a majority in aggregate principal amount of the Outstanding Securities represented at such meeting, may, on behalf of the Holders of all of the Securities, waive an existing Default or Event of Default, except a Default or Event of Default:

(1) in the payment of the principal of or premium, if any, or interest (including Additional Amounts, if any) on any Security (provided, however, that subject to Section 4.7, the Holders of a majority in aggregate principal amount of the Outstanding Securities may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration); or

(2) in respect of a covenant or provision hereof which, under Section 7.2, cannot be modified or amended without the consent of the Holders 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; provided, however, that no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

The Holders of a majority in aggregate principal amount of the Outstanding Securities (or such lesser amount as shall have acted at a meeting pursuant to the provisions of this Indenture) shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that:

(2) the Trustee determines may be unduly prejudicial to the rights of the Holders not joining therein; or

The Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.

No Holder of any Security shall have any right to pursue any remedy with respect to this Indenture or the Securities (including, instituting any proceeding, judicial or otherwise, with respect to this Indenture or for the appointment of a receiver or trustee) unless:

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

(2) the Holders of at least 25% in aggregate principal amount of the Outstanding Securities shall have made written request to the Trustee to pursue the remedy;

(3) such Holder or Holders have offered to the Trustee indemnity satisfactory to it against any costs, expenses and liabilities incurred in complying with such request;

(4) the Trustee has failed to comply with the request for 60 days after its receipt of such notice, request and offer of indemnity; and

(5) during such 60-day period, no direction inconsistent with such written request has been given to the Trustee by the Holders of a majority in aggregate principal amount of the Outstanding Securities (or such amount as shall have acted at a meeting pursuant to the provisions of this Indenture);

provided, however, that no one or more of such Holders may use this Indenture to prejudice the rights of another Holder or to obtain preference or priority over another Holder.

Section 4.7 Unconditional Rights of Holders to Receive Payment and to Convert.

Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to receive payment of the principal of and premium, if any, and interest (including Additional Amounts, if any) on such Security on the Stated Maturity expressed in such Security (or, in the case of redemption, on the Redemption Date, or in the case of the exercise of a Repurchase Right, on the Repurchase Date) and to convert such Security in accordance with Article 12, and to bring an action for the enforcement of any such payment on or after such respective dates and such right to convert, and such rights shall not be impaired or affected without the consent of such Holder.

Section 4.8 Collection of Indebtedness and Suits for Enforcement by the Trustee.

(1) a Default or Event of Default is made in the payment of any interest (including Additional Amounts, if any) on any Security when such interest (including Additional Amounts, if any) becomes due and payable and such Default or Event of Default continues for a period of 30 days; or

(2) a Default or Event of Default is made in the payment of the principal of or premium, if any, on any Security at the Maturity thereof;

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 (as expressed therein or as a result of any acceleration effected pursuant to Section 4.2) on such Securities for principal and premium, if any, and interest (including Additional Amounts, if any) and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal and premium, if any, and on any overdue interest (including Additional Amounts, if any), calculated using the Interest Rate, 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.

If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company and collect the monies adjudged or decreed to be payable in the manner provided by law out of the property of the Company, wherever situated.

If an Event of Default occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.

In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or the property of the Company or its creditors, the Trustee (irrespective of whether the principal of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue principal or interest (including Additional Amounts, if any)) shall be entitled and empowered, by intervention in such proceeding or otherwise:

(1) to file and prove a claim for the whole amount of principal and premium, if any, and interest (including Additional Amounts, if any) owing and unpaid in respect of the Securities and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders of Securities allowed in such judicial proceeding; and

(2) to collect and receive any monies or other property payable or deliverable on any such claim and to distribute the same;

and any Custodian in any such judicial proceedings is hereby authorized by each Holder of Securities 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 of Securities, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and any other amounts due the Trustee under Section 5.8.

Nothing contained herein shall be deemed to authorize the Trustee to authorize or consent to or accept, or adopt on behalf of any Holder of a Security, 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 of a Security in any such proceeding.

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

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 2.12, no right or remedy conferred in this Indenture upon or reserved to the Trustee or to the Holders of Securities 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 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.

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 any acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders of Securities may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders of Securities, as the case may be.

Subject to Article 14, 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 on account of principal or premium, if any, or interest (including Additional Amounts, if any), upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

SECOND: To the payment of the amounts then due and unpaid for principal of and premium, if any, and interest (including Additional Amounts, if any) on the Securities 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 for principal and premium, if any, and interest (including Additional Amounts, if any), respectively; and

All parties to this Indenture agree, and each Holder of any Security by such Holder’s acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; 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 aggregate principal amount of the Outstanding Securities, or to any suit instituted by any Holder of any Security for the enforcement of the payment of the principal of or premium, if any, or interest (including Additional Amounts, if any) on any Security on or after the Stated Maturity expressed in such Security (or, in the case of redemption or exercise of a Repurchase Right, on or after the Redemption Date) or for the enforcement of the right to convert any Security in accordance with Article 12.

The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim to take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

(1) The Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture or the TIA, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(2) In the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; provided, however, that in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall examine the certificates or opinions to determine whether or not, on their face, they conform to the requirements to this Indenture (but need not investigate or confirm the accuracy of any facts stated therein).

(b) In case an Event of Default actually known to a Responsible Officer of the Trustee has occurred and is continuing, the Trustee shall exercise such of 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.

(c) No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that:

(1) This paragraph (c) shall not be construed to limit the effect of paragraph (a) of this Section 5.1;

(2) The Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts; and

(3) The Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with a direction received by it of the Holders of a majority in principal amount of the Outstanding Securities (or such lesser amount as shall have acted at a meeting pursuant to the provisions of this Indenture) relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture.

(d) Whether or not herein expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section 5.1.

(e) No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers. The Trustee may refuse to perform any duty or exercise any right or power unless it receives indemnity satisfactory to it against any loss, liability, cost or expense (including, without limitation, reasonable fees of counsel).

(f) The Trustee shall not be obligated to pay interest on any money or other assets received by it unless otherwise agreed in writing with the Company. Assets held in trust by the Trustee need not be segregated from other funds except to the extent required by law.

(g) 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, coupon, other evidence of indebtedness or other paper or document, 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.

(h) The Trustee shall not be deemed to have notice or actual knowledge of any Event of Default unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact a Default is received by the Trustee pursuant to Section 15.2, and such notice references the Securities and this Indenture.

(i) The rights, privileges, protections, immunities and benefits given to the Trustee hereunder, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each Paying Agent, authenticating agent, Conversion Agent or Registrar acting hereunder.

Subject to the provisions of Section 5.1 and subject to Section 315(a) through (d) of the TIA:

(1) The Trustee may rely on any document believed by it to be genuine and to have been signed or presented by the proper person. The Trustee need not investigate any fact or matter stated in the document.

(2) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel, or both. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on the Officers’ Certificate or Opinion of Counsel.

(3) The Trustee may act through attorneys and agents and shall not be responsible for the misconduct or negligence of any attorney or agent appointed with due care.

(4) The Trustee shall not be liable for any action taken or omitted to be taken by it in good faith which it believed to be authorized or within the discretion or rights or powers conferred upon it by this Indenture, unless the Trustee’s conduct constitutes negligence.

(5) The Trustee may consult with counsel of its selection and the advice of such counsel as to matters of law shall be full and complete authorization and protection in respect of any action taken, omitted or suffered by it hereunder in good faith and in accordance with the advice or opinion of such counsel.

(6) Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Company shall be sufficient if signed by an Officer of the Company.

(7) The permissive rights of the Trustee to do things enumerated in this Indenture shall not be construed as a duty unless so specified herein.

The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest (as such term is defined in Section 310(b) of the TIA), it must eliminate such conflict within 90 days, apply to the SEC for permission to continue as trustee (to the extent permitted under Section 310(b) of the TIA) or resign. Any agent may do the same with like rights and duties. The Trustee is also subject to Sections 5.11 and 5.12.

Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as otherwise expressly agreed with the Company.

The recitals contained herein and in the Securities (except for those in the certificate of authentication) shall be taken as the statements of the Company, and the Trustee assumes no responsibility for their correctness. The Trustee makes no representations as to the validity, sufficiency or priority of this Indenture or of the Securities. The Trustee shall not be accountable for the use or application by the Company of Securities or the proceeds thereof.

Within 90 days after the occurrence of any Default or Event of Default hereunder of which the Trustee has received written notice, the Trustee shall give notice to Holders pursuant to Section 15.2, unless such Default or Event of Default shall have been cured or waived; provided, however, that, except in the case of a Default or Event of Default in the payment of the principal of or premium, if any, or interest (including Additional Amounts, if any), or in the payment of any redemption or repurchase obligation on any Security, the Trustee shall be protected in withholding such notice if and so long as Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interest of the Holders.

The Trustee shall transmit to Holders such reports concerning the Trustee and its actions under this Indenture as may be required by Section 313 of the TIA at the times and in the manner provided by the TIA.

A copy of each report at the time of its mailing to Holders shall be filed with the SEC, if required, and each stock exchange, if any, on which the Securities are listed. The Company shall promptly notify the Trustee when the Securities become listed on any stock exchange.

The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled to, reasonable compensation (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) and the Company covenants and agrees to pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by or on behalf of it in accordance with any of the provisions of this Indenture (including the reasonable compensation and the expenses and disbursements of its counsel and of all agents and other persons not regularly in its employ), except to the extent that any such expense, disbursement or advance is due to its negligence or bad faith. When the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 4.1, the expenses (including the reasonable charges and expenses of its counsel) and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law. The Company also covenants to indemnify the Trustee and its officers, directors, employees and agents for, and to hold such Persons harmless against, any loss, liability or expense incurred by them, arising out of or in connection with the

acceptance or administration of this Indenture or the trusts hereunder or the performance of their duties hereunder, including the costs and expenses of defending themselves against or investigating any claim of liability in the premises, except to the extent that any such loss, liability or expense was due to the negligence or willful misconduct of such Persons. The obligations of the Company under this Section 5.8 to compensate and indemnify the Trustee and its officers, directors, employees and agents and to pay or reimburse such Persons for expenses, disbursements and advances shall constitute additional indebtedness hereunder and shall survive the satisfaction and discharge of this Indenture or the earlier resignation or removal of the Trustee. Such additional indebtedness shall be a lien prior to that of the Securities upon all property and funds held or collected by the Trustee as such, except funds held in trust for the benefit of the Holders of particular Securities, and the Securities are hereby subordinated to such senior claim. “Trustee” for purposes of this Section 5.8 shall include any predecessor Trustee, but the negligence or willful misconduct of any Trustee shall not affect the indemnification of any other Trustee.

A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 5.9.

The Trustee may resign and be discharged from the trust hereby created by so notifying the Company in writing. The Holders of at least a majority in aggregate principal amount of Outstanding Securities may remove the Trustee by so notifying the Trustee and the Company in writing. The Company must remove the Trustee if:

(iii) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law; or

If the Trustee resigns or is removed or if a vacancy exists in the office of the Trustee for any reason, the Company shall promptly appoint a successor Trustee. The Trustee shall be entitled to payment of its fees and reimbursement of its expenses while acting as Trustee. Within one year after the successor Trustee takes office, the Holders of at least a majority in aggregate principal amount of Outstanding Securities may appoint a successor Trustee to replace the successor Trustee appointed by the Company.

Any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee if the Trustee fails to comply with Section 5.11.

If an instrument of acceptance by a successor Trustee shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation or removal, the resigning or removed Trustee, as the case may be, may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Trustee.

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this

Indenture. The Company shall issue a notice of the successor Trustee’s succession to the Holders. Upon payment of its charges, the retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject nevertheless to its lien, if any, provided for in Section 5.8. Notwithstanding replacement of the Trustee pursuant to this Section 5.9, the Company’s obligations under Section 5.8 shall continue for the benefit of the retiring Trustee with respect to expenses, losses and liabilities incurred by it prior to such replacement.

Subject to Section 5.11, if the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business (including the administration of this Indenture) to, another Person, corporation or national banking association, the successor entity without any further act shall be the successor Trustee as to the Securities.

The Trustee shall at all times satisfy the requirements of Section 310(a)(1), (2) and (5) of the TIA. The Trustee shall at all times have (or, in the case of a corporation included in a bank holding company system, the related bank holding company shall at all times have), a combined capital and surplus of at least $25 million as set forth in its (or its related bank holding company’s) most recent published annual report of condition. The Trustee is subject to Section 310(b) of the TIA.

The Trustee is subject to Section 311(a) of the TIA, excluding any creditor relationship listed in Section 311(b) of the TIA. A Trustee who has resigned or been removed shall be subject to Section 311(a) of the TIA to the extent indicated therein.

The Company shall not consolidate with or merge into any other Person or convey, transfer or lease its properties and assets substantially as an entirety to any Person, and the Company shall not permit any Person to consolidate with or merge into the Company or convey, transfer or lease its properties and assets substantially as an entirety to the Company, unless:

(1) in the event that the Company shall consolidate with or merge into another Person or convey, transfer or lease its properties and assets substantially as an entirety to any Person, the Person formed by such consolidation or into which the Company is merged or the Person which acquires by conveyance or transfer, or which leases, the properties and assets of the Company substantially as an entirety shall be a corporation, limited liability company, partnership or trust organized and validly existing under the laws of the United States of America, any State thereof or the District of Columbia and, if the entity surviving such transaction or transferee entity is not the Company, then such surviving or transferee entity shall expressly assume, by an indenture supplemental hereto, executed and delivered to the Trustee, in form satisfactory to the Trustee, the due and punctual payment of the principal of and premium, if any and interest (including

Additional Amounts, if any), on all the Securities and the performance of every covenant of this Indenture on the part of the Company to be performed or observed and shall have provided for conversion rights in accordance with Section 12.11;

(2) at the time of consummation of such transaction, no Event of Default, and no event which, after notice or lapse of time or both, would become an Event of Default, shall have happened and be continuing; and

(3) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger, conveyance, transfer or lease and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture, comply with this Article and that all conditions precedent herein provided for relating to such transaction have been complied with.

Upon any consolidation or merger by the Company with or into any other corporation or any conveyance, transfer or lease of the properties and assets of the Company substantially as an entirety to any Person, in accordance with Section 6.1, the successor corporation formed by such consolidation or into which the Company is merged or to which such conveyance, transfer or lease is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture with the same effect as if such successor corporation had been named as the Company herein, and thereafter, except in the case of a lease to another Person, the predecessor corporation shall be relieved of all obligations and covenants under this Indenture and the Securities.

Without the consent of any Holders of Securities, the Company, when authorized by a Board Resolution, and the Trustee, at any time and from time to time, may amend this Indenture and the Securities to:

(a) add to the covenants of the Company for the benefit of the Holders of Securities;

(d) provide for the assumption of the Company’s obligations to the Holders of Securities in the case of a merger, consolidation, conveyance, transfer or lease pursuant to Article 6;

(e) reduce the Conversion Price; provided, however, that such reduction in the Conversion Price shall not adversely affect the interest of the Holders of Securities (after taking into account tax and other consequences of such reduction);

(f) comply with the requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA;

(g) make any changes or modifications to this Indenture necessary in connection with the registration of any Securities under the Securities Act as contemplated in the Registration Rights Agreement; provided, however, that such action pursuant to this clause (g) does not, in the good faith opinion of the Board of Directors (as evidenced by a Board Resolution) and the Trustee, adversely affect the interests of the Holders of Securities in any material respect;

(h) cure any ambiguity, to correct or supplement any provision herein which may be inconsistent with any other provision herein or which is otherwise defective, or to make any other provisions with respect to matters or questions arising under this Indenture which the Company and the Trustee may deem necessary or desirable and which shall not be inconsistent with the provisions of this Indenture; provided, however, that such action pursuant to this clause (h) does not, in the good faith opinion of the Board of Directors (as evidenced by a Board Resolution) and the Trustee, adversely affect the interests of the Holders of Securities in any material respect;

(i) add or modify any other provisions with respect to matters or questions arising under this Indenture which the Company and the Trustee may deem necessary or desirable and which shall not be inconsistent with the provisions of this Indenture; provided, however, that such action pursuant to this clause (i) does not, in the good faith opinion of the Board of Directors (as evidenced by a Board Resolution) and the Trustee, adversely affect the interests of the Holders of Securities in any material respect; or

(j) make provision for the establishment of a book-entry system, in which Holders would have the option to participate, for the clearance and settlement of transactions in Securities originally issued in definitive form.

Except as provided below in this Section 7.2, this Indenture or the Securities may be amended or supplemented, and noncompliance in any particular instance with any provision of this Indenture or the Securities may be waived, in each case (i) with the written consent of the Holders of at least a majority in aggregate principal amount of the Outstanding Securities or (ii) by the adoption of a resolution, at a meeting of Holders of the Outstanding Securities at which a quorum is present, by the Holders of a majority in aggregate principal amount of the Outstanding Securities represented at such meeting.

Without the written consent or the affirmative vote of each Holder of Securities affected thereby, an amendment or waiver under this Section 7.2 may not:

(a) change the Stated Maturity of the principal of, or any installment of interest (including Additional Amounts, if any) on, any Security;

(d) change the currency of payment of principal of, premium, if any, or interest (including Additional Amounts, if any) on any Security;

(e) impair the right of any Holder to institute suit for the enforcement of any payment in or with respect to any Security;

(f) modify the obligation of the Company to maintain an office or agency in The City of New York pursuant to Section 9.2;

(g) except as permitted by Section 12.11, adversely affect the Repurchase Right or the right to convert any Security as provided in Article 12;

(h) modify the provisions in Article 14 relating to the subordination of the Securities in a manner adverse to the Holders of Securities;

(i) modify the provisions in Article 10 relating to the redemption of the Securities in a manner adverse to the Holders of Securities;

(j) modify any of the provisions of this Section, Section 4.4 or Section 15.11, except to increase any percentage contained herein or therein or to provide that certain other provisions of this Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Security affected thereby; or

(k) reduce the requirements of Section 8.4 for quorum or voting, or reduce the percentage in aggregate principal amount of the Outstanding Securities the consent of whose Holders is required for any such supplemental indenture or the consent of whose Holders is required for any waiver provided for in this Indenture.

It shall not be necessary for any Act of Holders of Securities under this Section 7.2 to approve the particular form of any proposal supplemental indenture, but it shall be sufficient if such Act shall approve the substance thereof.

Every amendment to this Indenture or the Securities shall be set forth in a supplemental indenture that complies with the TIA as then in effect.

Until an amendment, supplement or waiver becomes effective, a written consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent is not made on any Security; provided, however, that unless a record date shall have been established, any such Holder or subsequent Holder may revoke the consent as to its Security or portion of a Security if the Trustee receives written notice of revocation before the date the amendment, supplement or waiver becomes effective.

An amendment, supplement or waiver becomes effective on receipt by the Trustee of written consents from or affirmative votes by, as the case may be, the Holders of the requisite percentage of aggregate principal amount of the Outstanding Securities, and thereafter shall bind every Holder of Securities; provided, however, if the amendment, supplement or waiver makes a change described in any of the clauses (a) through (k) of Section 7.2, the amendment, supplement or waiver shall bind only each Holder of a Security which has consented to it or voted for it, as the case may be, and every subsequent Holder of a Security or portion of a Security that evidences the same indebtedness as the Security of the consenting or affirmatively voting Holder, as the case may be.

(a) the Trustee may require the Holder of a Security to deliver such Securities to the Trustee, the Trustee may place an appropriate notation on the Security about the changed terms and return it to the Holder and the Trustee may place an appropriate notation on any Security thereafter authenticated; or

(b) if the Company or the Trustee so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms.

Failure to make the appropriate notation or issue a new Security shall not affect the validity and effect of such amendment, supplement or waiver.

The Trustee shall sign any amendment authorized pursuant to this Article 7 if the amendment does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If the amendment does adversely affect the rights, duties, liabilities or immunities of the Trustee, the Trustee may but need not sign it. In signing or refusing to sign such amendment, the Trustee shall be entitled to receive and shall be fully protected in relying upon an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that such amendment is authorized or permitted by this Indenture.

A meeting of Holders of Securities may be called at any time and from time to time pursuant to this Article to make, give or take any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be made, given or taken by Holders of Securities.

(a) The Trustee may at any time call a meeting of Holders of Securities for any purpose specified in Section 8.1, to be held at such time and at such place in The City of New York. Notice of every meeting of Holders of Securities, setting forth the time and the place of such meeting and in general terms the action proposed to be taken at such meeting, shall be given, in the manner provided in Section 15.2, not less than 21 nor more than 180 days prior to the date fixed for the meeting.

(b) In case at any time the Company, pursuant to a Board Resolution, or the Holders of at least 10% in principal amount of the Outstanding Securities shall have requested the Trustee to call a meeting of the Holders of Securities for any purpose specified in Section 8.1, by written request setting forth in reasonable detail the action proposed to be taken at the meeting, and the Trustee shall not have

made the first publication of the notice of such meeting within 21 days after receipt of such request or shall not thereafter proceed to cause the meeting to be held as provided herein, then the Company or the Holders of Securities in the amount specified, as the case may be, may determine the time and the place in The City of New York for such meeting and may call such meeting for such purposes by giving notice thereof as provided in paragraph (a) of this Section 8.2.

To be entitled to vote at any meeting of Holders of Securities, a Person shall be (a) a Holder of one or more Outstanding Securities, or (b) a Person appointed by an instrument in writing as proxy for a Holder or Holders of one or more Outstanding Securities by such Holder or Holders. The only Persons who shall be entitled to be present or to speak at any meeting of Holders shall be the Persons entitled to vote at such meeting and their counsel, any representatives of the Trustee and its counsel and any representatives of the Company and its counsel.

The Persons entitled to vote a majority in principal amount of the Outstanding Securities shall constitute a quorum. In the absence of a quorum within 30 minutes of the time appointed for any such meeting, the meeting shall, if convened at the request of Holders of Securities, be dissolved. In any other case, the meeting may be adjourned for a period of not less than 10 days as determined by the chairman of the meeting prior to the adjournment of such meeting. In the absence of a quorum at any such adjourned meeting, such adjourned meeting may be further adjourned for a period of not less than 10 days as determined by the chairman of the meeting prior to the adjournment of such adjourned meeting. Notice of the reconvening of any adjourned meeting shall be given as provided in Section 8.2(a), except that such notice need be given only once and not less than five days prior to the date on which the meeting is scheduled to be reconvened. Notice of the reconvening of an adjourned meeting shall state expressly the percentage of the principal amount of the Outstanding Securities which shall constitute a quorum.

Subject to the foregoing, at the reconvening of any meeting adjourned for a lack of a quorum, the Persons entitled to vote 25% in principal amount of the Outstanding Securities at the time shall constitute a quorum for the taking of any action set forth in the notice of the original meeting.

At a meeting or an adjourned meeting duly reconvened and at which a quorum is present as aforesaid, any resolution and all matters (except as limited by the proviso to Section 7.2) shall be effectively passed and decided if passed or decided by the Persons entitled to vote not less than a majority in principal amount of Outstanding Securities represented and voting at such meeting.

Any resolution passed or decisions taken at any meeting of Holders of Securities duly held in accordance with this Section shall be binding on all the Holders of Securities, whether or not present or represented at the meeting.

Section 8.5 Determination of Voting Rights; Conduct and Adjournment of Meetings.

(a) Notwithstanding any other provisions of this Indenture, the Trustee may make such reasonable regulations as it may deem advisable for any meeting of Holders of Securities in regard to proof of the holding of Securities and of the appointment of proxies and in regard to the appointment and duties of inspectors of votes, the submission and examination of proxies, certificates and other evidence of the right to vote, and such other matters concerning the conduct of the meeting as it shall deem appropriate. Except as otherwise permitted or required by any such regulations, the holding of

Securities shall be proved in the manner specified in Section 1.3 and the appointment of any proxy shall be proved in the manner specified in Section 1.3. Such regulations may provide that written instruments appointing proxies, regular on their face, may be presumed valid and genuine without the proof specified in Section 1.3 or other proof.

(b) The Trustee shall, by an instrument in writing, appoint a temporary chairman (which may be the Trustee) of the meeting, unless the meeting shall have been called by the Company or by Holders of Securities as provided in Section 8.2(b), in which case the Company or the Holders of Securities calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the meeting shall be elected by vote of the Persons entitled to vote a majority in principal amount of the Outstanding Securities represented at the meeting.

(c) At any meeting, each Holder of a Security or proxy shall be entitled to one vote for each $1,000 principal amount of Securities held or represented by him; provided, however, that no vote shall be cast or counted at any meeting in respect of any Security challenged as not Outstanding and ruled by the chairman of the meeting to be not Outstanding. The chairman of the meeting shall have no right to vote, except as a Holder of a Security or proxy.

(d) Any meeting of Holders of Securities duly called pursuant to Section 8.2 at which a quorum is present may be adjourned from time to time by Persons entitled to vote a majority in principal amount of the Outstanding Securities represented at the meeting, and the meeting may be held as so adjourned without further notice.

The vote upon any resolution submitted to any meeting of Holders of Securities shall be by written ballots on which shall be subscribed the signatures of the Holders of Securities or of their representatives by proxy and the principal amounts and serial numbers of the Outstanding Securities held or represented by them. The permanent chairman of the meeting shall appoint two inspectors of votes who shall count all votes cast at the meeting for or against any resolution and who shall make and file with the secretary of the meeting their verified written reports in duplicate of all votes cast at the meeting. A record, at least in duplicate, of the proceedings of each meeting of Holders of Securities shall be prepared by the secretary of the meeting and there shall be attached to said record the original reports of the inspectors of votes on any vote by ballot taken thereat and affidavits by one or more Persons having knowledge of the facts setting forth a copy of the notice of the meeting and showing that said notice was given as provided in Section 8.2 and, if applicable, Section 8.4. Each copy shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one such copy shall be delivered to the Company and another to the Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting. Any record so signed and verified shall be conclusive evidence of the matters therein stated.

The Company will duly and punctually pay the principal of and premium, if any, and interest (including Additional Amounts, if any) in respect of the Securities in accordance with the terms of the Securities and this Indenture. The Company will deposit or cause to be deposited with the Trustee as directed by the Trustee, no later than the day of the Stated Maturity of any Security or installment of interest (including Additional Amounts, if any), all payments so due.

The Company hereby appoints the Corporate Trust Office of U.S. Bank National Association and its affiliated office in The City of New York, where Securities may be:

and where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served.

The Company may at any time and from time to time vary or terminate the appointment of any such office or appoint any additional offices for any or all of such purposes; provided, however, that until all of the Securities have been delivered to the Trustee for cancellation, or monies sufficient to pay the principal of and premium, if any, and interest (including Additional Amounts, if any) on the Securities have been made available for payment and either paid or returned to the Company pursuant to the provisions of Section 9.3, the Company will maintain in 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 or exchange, where Securities may be surrendered for conversion and where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served. The Company will give prompt written notice to the Trustee, and notice to the Holders in accordance with Section 15.2, of the appointment or termination of any such agents and of the location and any change in the location of any such office or agency.

If at any time the Company shall fail to maintain any such required office or agency in The City of New York, or shall fail to furnish the Trustee with the address thereof, presentations and surrenders may be made at, and notices and demands may be served on, the Corporate Trust Office of the Trustee.

Subject to Article 6, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate 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 Company determines 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.

The Company will maintain and keep its properties and every part thereof in such repair, working order and condition, and make or cause to be made all such needful and proper repairs, renewals and replacements thereto, as in the judgment of the Company are necessary in the interests of the Company; provided, however, that nothing contained in this Section shall prevent the Company from selling, abandoning or otherwise disposing of any of its properties or discontinuing a part of its business

from time to time if, in the judgment of the Company, such sale, abandonment, disposition or discontinuance is advisable and does not materially adversely affect the interests or business of the Company.

The Company will, and will cause any Significant Subsidiary to, promptly pay and discharge or cause to be paid and discharged all material taxes, assessments and governmental charges or levies lawfully imposed upon it or upon its income or profits or upon any of its property, real or personal, or upon any part thereof, as well as all material claims for labor, materials and supplies which, if unpaid, might by law become a lien or charge upon its property; provided, however, that neither the Company nor any Significant Subsidiary shall be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge, levy, or claim if the amount, applicability or validity thereof shall currently be contested in good faith by appropriate proceedings and if the Company or such Significant Subsidiary, as the case may be, shall have set aside on its books reserves deemed by it adequate with respect thereto.

(a) The Company shall deliver to the Trustee within 15 days after it files them with the SEC copies of the annual reports and of the information, documents, and other reports (or copies of such portions of any of the foregoing as the SEC may by rules and regulations prescribe) which the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act; provided, however, the Company shall not be required to deliver to the Trustee any materials for which the Company has sought and received confidential treatment by the SEC. The Company also shall comply with the other provisions of Section 314(a) of the TIA.

(b) If at any time the Company is not subject to Section 13 or 15(d) of the Exchange Act, upon the request of a Holder of a Security, the Company will promptly furnish or cause to be furnished to such Holder or to a prospective purchaser of such Security designated by such Holder, as the case may be, the information, if any, required to be delivered by it pursuant to Rule 144A(d)(4) under the Securities Act to permit compliance with Rule 144A in connection with the resale of such Security; provided, however, that the Company shall not be required to furnish such information in connection with any request made on or after the date which is two years from the later of the date such security was last acquired from the Company or an “affiliate” (as defined under Rule 144 under the Securities Act) of the Company.

The Company shall deliver to the Trustee, within 120 days after the end of each fiscal year of the Company (which as of the date hereof is September 30), an Officers’ Certificate stating that in the course of the performance by the signers of their duties as Officers of the Company, they would normally have knowledge of any failure by the Company to comply with all conditions, or any Default by the Company with respect to any covenants, under this Indenture, and further stating whether or not they have knowledge of any such failure or Default and, if so, specifying each such failure or Default and the nature thereof. In the event an Officer of the Company comes to have actual knowledge of a Default, regardless of the date, the Company shall deliver an Officers’ Certificate to the Trustee specifying such Default and the nature and status thereof.

During the period of two years after the last date of original issuance of any Securities, the Company shall not, and shall not permit any of its “affiliates” (as defined under Rule 144 under the Securities Act) to, resell any Securities, or shares of Common Stock issuable upon conversion of the Securities, which constitute “restricted securities” under Rule 144, that are acquired by any of them within the United States or to “U.S. persons” (as defined in Regulation S) except pursuant to an effective registration statement under the Securities Act or an applicable exemption therefrom. The Trustee shall have no responsibility or liability in respect of the Company’s performance of its agreement in the preceding sentence.

If Additional Amounts are payable by the Company pursuant to the Registration Rights Agreement, the Company shall deliver to the Trustee a certificate to that effect stating (i) the amount of such Additional Amounts that are payable and (ii) the date on which such Additional Amounts are payable. Unless and until a Responsible Officer of the Trustee receives such a certificate, the Trustee may assume without inquiry that no Additional Amounts are payable. If the Company has paid Additional Amounts directly to the persons entitled to them, the Company shall deliver to the Trustee a certificate setting forth the particulars of such payment.

On or after October 1, 2009, the Company may, at its option, redeem the Securities in whole at any time or in part from time to time, on any date prior to Maturity, upon notice as set forth in Section 10.4, at the Redemption Price plus any interest (including Additional Amounts, if any) accrued and unpaid to, but excluding, the Redemption Date; provided, however, that the Company may redeem the Securities in whole at any time or in part from time to time, on any date after October 1, 2007 and prior to October 1, 2009, upon notice as set forth in Section 10.4, at the Redemption Price plus any interest (including Additional Amounts, if any) accrued and unpaid to, but excluding, the Redemption Date, if the closing sale price of the Common Stock has been at least 170% of the Conversion Price then in effect for at least 20 Trading Days during any 30 consecutive Trading Day period.

In the event that the closing sale price of the Common Stock has been at least 170% of the Conversion Price then in effect for at least 20 Trading Days during any 30 consecutive Trading Day period ending prior to October 1, 2009, the Company shall promptly provide the Trustee with a written notice of the occurrence of such event, and the Trustee shall promptly thereafter mail such written notice to the Holders pursuant to Section 15.2.

If the Company elects to redeem Securities pursuant to the provisions of Section 10.1, it shall notify the Trustee at least 30 days (unless a shorter period is reasonably acceptable to the Trustee) prior to the intended Redemption Date of (i) such intended Redemption Date, (ii) the principal amount of Securities to be redeemed and (iii) the CUSIP numbers of the Securities to be redeemed.

If fewer than all the Securities are to be redeemed, the Trustee shall select the particular Securities to be redeemed in principal amounts of $1,000 or whole multiples of $1,000 from the Outstanding Securities by a method that complies with the requirements of any exchange on which the Securities are listed, or, if the Securities are not listed on an exchange, on a pro rata basis or by lot or in accordance with any other method the Trustee considers fair and appropriate. Securities and portions thereof that the Trustee selects shall be in amounts equal to the minimum authorized denominations for Securities to be redeemed or any integral multiple thereof.

If any Security selected for partial redemption is converted in part before termination of the conversion right with respect to the portion of the Security so selected, the converted portion of such Security shall be deemed to be the portion selected for redemption; provided, however, that the Holder of such Security so converted and deemed redeemed shall not be entitled to any additional interest payment as a result of such deemed redemption than such Holder would have otherwise been entitled to receive upon conversion of such Security. Securities which have been converted during a selection of Securities to be redeemed may be treated by the Trustee as Outstanding for the purpose of such selection.

The Trustee shall promptly notify the Company and the Registrar in writing of the Securities selected for redemption and, in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed.

For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion of the principal amount of such Securities which has been or is to be redeemed.

Notice of redemption shall be given in the manner provided in Section 15.2 to the Holders of Securities to be redeemed. Such notice shall be given not less than 20 nor more than 60 days prior to the intended Redemption Date.

(2) the Redemption Price and interest (including Additional Amounts, if any) accrued and unpaid to, but excluding, the Redemption Date, if any;

(3) if fewer than all the Outstanding Securities are to be redeemed, the aggregate principal amount of Securities to be redeemed and the aggregate principal amount of Securities which will be Outstanding after such partial redemption;

(4) that on the Redemption Date the Redemption Price and interest accrued and unpaid to, but excluding, the Redemption Date, if any, will become due and payable upon each such Security to be redeemed, and that interest (including Additional Amounts, if any) thereon shall cease to accrue on and after such date;

(5) the Conversion Price, the date on which the right to convert the principal of the Securities to be redeemed will terminate, whether the Company has elected to settle

its obligation upon conversion in cash or a combination of cash and shares of Common Stock in lieu of shares of Common Stock only (and, in the event that the Company has elected to settle all or a portion of its conversion obligation in cash, the date on which the Cash Settlement Averaging Period will begin) and the places where such Securities may be surrendered for conversion;

(6) the place or places where such Securities are to be surrendered for payment of the Redemption Price, accrued and unpaid interest, if any; and

The notice given shall specify the last date on which exchanges or transfers of Securities may be made pursuant to Section 2.7, and shall specify the serial numbers of Securities, if Physical Securities are selected for redemption, and the portions thereof called for redemption.

Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, at the Company’s request, by the Trustee in the name of and at the expense of the Company.

Notice of redemption having been given as provided in Section 10.4, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued and unpaid interest) such Securities shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with such notice, such Security shall be paid by the Company at the Redemption Price; provided, however, the installments of interest on Securities whose Stated Maturity is prior to or on the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such on the relevant Record Date according to their terms and the provisions of Section 2.7.

If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal and premium, if any, shall, until paid, bear interest from the Redemption Date at the Interest Rate.

Prior to 11:00 a.m. (New York City time) on any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent an amount of money sufficient to pay the Redemption Price, and accrued and unpaid interest (including Additional Amounts, if any), in respect of all the Securities to be redeemed on that Redemption Date, other than any Securities called for redemption on that date which have been converted prior to the date of such deposit, and accrued and unpaid interest, if any, on such Securities.

If any Security called for redemption is converted, any money deposited with the Trustee or with a Paying Agent or so segregated and held in trust for the redemption of such Security shall (subject to any right of the Holder of such Security or any Predecessor Security to receive interest as provided in the fourth to last paragraph of Section 2.1) be paid to the Company on Company Request or, if then held by the Company, shall be discharged from such trust.

Any Security which is to be redeemed only in part shall be surrendered at an office or agency of the Company designated for that purpose pursuant to Section 9.2 (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 the 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 unredeemed portion of the principal of the Security so surrendered.

REPURCHASE AT THE OPTION OF A HOLDER UPON SPECIFIC REPURCHASE DATES OR UPON A FUNDAMENTAL CHANGE

(a) On October 1, 2009, 2014 and 2019, (each, a “Specific Repurchase Date”) each Holder shall have the right (the “Repurchase Right”), at the Holder’s option, to require the Company to purchase for cash, and upon the exercise of such right the Company shall purchase, all of such Holder’s Securities not previously called for redemption, or any portion of the principal amount thereof that is equal to $1,000 or an integral multiple thereof as directed by such Holder pursuant to Section 11.3 (provided that no single Security may be repurchased in part unless the portion of the principal amount of such Security to be Outstanding after such repurchase is equal to $1,000 or an integral multiple thereof), at a purchase price equal to 100% of the principal amount of the Securities to be purchased (the “Repurchase Price”), plus accrued and unpaid interest and Additional Amounts, if any, on such Securities to, but excluding the Specific Repurchase Date. Holders may submit their Securities for repurchase to the Paying Agent at any time from the opening of business on the date that is 20 Business Days prior to the applicable Specific Repurchase Date until the close of business on the Business Day prior to the applicable Specific Repurchase Date.

(b) In the event that a Fundamental Change (together with the Specific Repurchase Dates, “Repurchase Events”) shall occur, each Holder shall have the right, at the Holder’s option, but subject to the provisions of Section 11.2 hereof, to require the Company to repurchase, and upon the exercise of such right the Company shall repurchase, all of such Holder’s Securities not previously called for redemption, or any portion of the principal amount thereof that is equal to $1,000 or an integral multiple thereof as directed by such Holder pursuant to Section 11.3 (provided that no single Security may be repurchased in part unless the portion of the principal amount of such Security to be Outstanding after such repurchase is equal to $1,000 or an integral multiple thereof), on a date (the “Fundamental Change Repurchase Date” and, together with the Specific Repurchase Date, the “Repurchase Date”) that is not less than 20 nor more than 35 Business Days after the date of the Repurchase Event Notice for an amount equal to the sum of (i) the Repurchase Price plus accrued and unpaid interest and Additional Amounts, if any, to, but excluding, the Fundamental Change Purchase Date and (ii) the Make-Whole Premium, if any; provided, however, that installments of interest on Securities whose Stated Maturity is prior to or on the Fundamental Change Purchase Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such on the relevant Regular Record Date according to their terms and the provisions of Section 2.1 hereof.

(c) If the Holders have a repurchase right pursuant to this Section 11.1, the Company shall issue a press release through Dow Jones & Company, Inc, Business Wire or Bloomberg Business News (or, if such organizations are not in existence at the time of issuance of such press release, such other news or press organization as is reasonably calculated to broadly disseminate the relevant information to the public) containing the relevant information and make such information available on the Company’s web site or through another public medium as the Company may use at such time.

Section 11.2 Company’s Option to Pay All or a Portion of the Repurchase Price in the Event of a Fundamental Change in Common Stock; Conditions to the Company’s Election to Pay the Repurchase Price in the Event of a Fundamental Change in Common Stock.

(a) The Repurchase Price payable in the event of a Fundamental Change shall be payable at the Company’s option in the same forms of consideration that the Company may use in satisfaction of its obligation upon conversion of the Securities pursuant to Article 12, including cash, shares of Common Stock or a combination of cash and shares of Common Stock. However, if the Company has irrevocably elected to make a cash payment of principal upon conversion pursuant to Section 12.12(f) hereof, the Company shall repay the principal amount of the Securities repurchased in the event of a Fundamental Change in cash, with any remaining amount to be satisfied in shares of Common Stock.

(b) The Company may, at its option, pay the Repurchase Price payable to Holders payable in the event of the occurrence of a Fundamental Change pursuant to Section 11.1(b) upon redemption of the Securities, in whole or in part in shares of Common Stock, if the following conditions are satisfied:

(A) shall not require registration under any federal securities law before such shares may be freely transferable without being subject to any transfer restrictions under the Securities Act upon repurchase or redemption, as the case may be, or if such registration is required, such registration shall be completed and shall become effective prior to the Repurchase Date; and

(B) shall not require registration with, or approval of, any governmental authority under any state law or any other federal law before shares may be validly issued or delivered upon repurchase or redemption or if such registration is required or such approval must be obtained, such registration shall be completed or such approval shall be obtained prior to the Repurchase Date.

(ii) The shares of Common Stock to be listed upon repurchase of Securities hereunder are, or shall have been, approved for listing on the Nasdaq National Market or the New York Stock Exchange or listed on another national securities exchange, in any case, prior to the Repurchase Date.

(iii) All shares of Common Stock which may be issued upon repurchase of Securities will be issued out of the Company’s authorized but unissued Common Stock or treasury stock and will, upon issue, be duly and validly issued and fully paid and nonassessable and free of any preemptive or similar rights.

If any of the conditions set forth in clauses (i) through (iii) of this Section 11.2(b) are not satisfied in accordance with the terms thereof, the Repurchase Price payable in the event of a Fundamental Change shall be paid by the Company only in cash.

No later than 10 Business Days after the occurrence of a Fundamental Change and at least 20 Business Days prior to the occurrence of any Specific Repurchase Date, the Company shall mail a written notice of the Repurchase Event (the “Repurchase Event Notice”) by first-class mail to the Trustee and to each Holder (and to beneficial owners to the extent practicable) pursuant to Section 15.2. The Repurchase Event Notice shall include a form of notice (the “Repurchase Event Purchase Notice”) to be completed by the Holder and delivered to the Paying Agent pursuant to Section 11.4, and shall state the following:

(2) in the event of a repurchase upon the occurrence of a Fundamental Change, the event causing the Repurchase Event and the date of such Repurchase Event;

(3) the procedures with which such Holder must comply to exercise its right to have its Securities purchased pursuant to Section 11.1, including the date by which the completed Repurchase Event Purchase Notice pursuant to Section 11.4 and the Securities the Holder elects to have purchased pursuant to Section 11.1 must be delivered to the Paying Agent in order to have such Securities purchased by the Company pursuant to Section 11.1, the name and address of the Paying Agent and that the Securities as to which a Repurchase Event Purchase Notice has been given may be converted, if they are otherwise convertible pursuant to Article 12, only if the completed and delivered Repurchase Event Purchase Notice has been withdrawn in accordance with the terms of the Indenture, the Holder’s conversion rights pursuant to Article 12 and the Conversion Price then in effect and any adjustments thereto;

(5) in the event of a repurchase upon the occurrence of a Fundamental Change, whether the Repurchase Price shall be paid by the Company in cash, by delivery of shares of Common Stock or both;

(6) that, unless the Company defaults in making payment of such Repurchase Price, interest and Additional Amounts, if any, on the Securities surrendered for purchase by the Company will cease to accrue on and after the Repurchase Date, if applicable; and

No failure by the Company to give the foregoing Repurchase Event Notice shall limit any Holder’s right to exercise its rights pursuant to Section 11.1 or affect the validity of the proceedings for the purchase of its Securities hereunder.

Section 11.4 Delivery of Repurchase Event Purchase Notice; Form of Repurchase Event Purchase Notice; Withdrawal of Repurchase Event Purchase Notice.

(a) The Company shall deliver, or cause the Trustee or Paying Agent, to deliver, to all Holders (and beneficial holders of the Securities to the extent practicable) a form of Repurchase Event Purchase Notice, which with respect to Holders’ Repurchase Rights set forth in Section 11.1, shall be delivered to such Holders at least 20 Business Days prior to the Repurchase Event Purchase Date and, as set forth in Section 11.3, shall be included in the Repurchase Event Notice; provided, that the delivery of such form of Repurchase Event Purchase Notice to the Holders shall be made in the Company’s name and at the Company’s expense and the text of such form of Repurchase Event Purchase Notice shall be prepared by the Company pursuant to clause (b) of this Section.

(4) any other procedures then applicable that the Holder must follow to exercise rights under Article 11 and a brief description of those rights;

(6) in the event of a repurchase upon the occurrence of a Fundamental Change, whether the Repurchase Price shall be paid by the Company in cash, by delivery of shares of Common Stock or both;

(7) the procedures with which such Holder must comply to exercise its right to have its Securities repurchased pursuant to Section 11.1, including the date by which the completed Repurchase Event Purchase Notice pursuant to Section 11.4 and the Securities the Holder elects to have repurchased pursuant to Section 11.1 must be delivered to Paying Agent in order to have such Securities repurchased by the Company pursuant to Section 11.1, the name and address of the Paying Agent and that the Securities as to which a Repurchase Event Purchase Notice has been given may be converted, if they are otherwise convertible pursuant to Article 12, only if the completed and delivered Repurchase Event Purchase Notice has been withdrawn in accordance with the terms of the Indenture, the Holder’s conversion rights pursuant to Article 12, the Conversion Price then in effect and any adjustments thereto;

(8) the Holder’s right to withdraw a completed and delivered Repurchase Event Purchase Notice, the procedures for withdrawing a Repurchase Event Purchase Notice, pursuant to clause (c) below and that Securities as to which a completed and delivered Repurchase Event Purchase Notice may be converted, if they are convertible only in accordance with Article 12, if the applicable completed and delivered Repurchase Event Purchase Notice has been withdrawn;

(9) that, unless the Company defaults in making payment on Securities for which a Repurchase Event Purchase Notice has been submitted, interest and Additional Amounts, if any, on such Securities will cease to accrue on the Repurchase Event Purchase Date; and

(c) Notwithstanding anything herein to the contrary, any Holder which has delivered a completed Repurchase Event Purchase Notice to the Paying Agent shall have the right to withdraw such Repurchase Event Purchase Notice by delivery of a written notice of withdrawal delivered to the office of the Paying Agent in accordance with the Repurchase Event Purchase Notice at any time prior to the close of business on the Business Day prior to the Repurchase Date specifying:

(1) the certificate number, if any, of the Security in respect of which such notice of withdrawal is being submitted;

(2) the principal amount of the Security with respect to which such notice of withdrawal is being submitted; and

(3) the principal amount, if any, of such Security which remains subject to the original Repurchase Event Purchase Notice and which has been or will be delivered for purchase by the Company.

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

To exercise a Repurchase Right pursuant to Section 11.1, a Holder must deliver to the Trustee at its offices on or prior to the Repurchase Date the following:

(a) a completed Repurchase Event Purchase Notice, the form of which is provided in Exhibit B hereto; and

(b) the Securities or cause such Securities to be delivered through the facilities of the Depositary, as applicable, with respect to which the Repurchase Right is being exercised, 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.

(a) In the event a Repurchase Right shall be exercised in accordance with the terms hereof, the Company shall pay or cause to be paid to the Trustee the Repurchase Price in cash or, in the event of a repurchase upon the occurrence of a Fundamental Change, cash, shares of Common Stock or both, as provided above, for payment to the Holder on the Repurchase Date or, with respect to any shares of Common Stock that are to be paid in the event of a repurchase upon the occurrence of a Fundamental Change, as promptly after the Repurchase Date as practicable, together with accrued and unpaid interest to, but excluding, the Repurchase Date payable in cash with respect to the Securities as to which the Repurchase Right has been exercised; provided, however, that installments of interest that mature prior to or on the Repurchase Date shall be payable in cash to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Regular Record Date.

(b) If any Security (or portion thereof) surrendered for repurchase shall not be so paid on the Repurchase Date, the principal amount of such Security (or portion thereof, as the case may be) shall, until paid, bear interest to the extent permitted by applicable law from the Repurchase Date at the Interest Rate, and each Security shall remain convertible into Common Stock until the principal of such Security (or portion thereof, as the case may be) shall have been paid or duly provided for.

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

(d) Any issuance of shares of Common Stock in respect of the Repurchase Price payable in the event of a repurchase upon the occurrence of a Fundamental Change shall be deemed to have been effected immediately prior to the close of business on the Repurchase Date and the Person or Persons in whose name or names any stock certificate or stock certificates representing shares of Common Stock shall be issuable upon such repurchase shall be deemed to have become on the Repurchase Date the holder or holders of record of the shares represented thereby; provided, however, that any surrender for repurchase on a date when the stock transfer books of the Company shall be closed shall constitute the Person or Persons in whose name or names the stock certificate or stock certificates representing such shares are to be issued as the holder or holders of record of the shares represented thereby for all purposes at the opening of business on the next succeeding day on which such stock transfer books are open. No payment or adjustment shall be made for dividends or distributions on any Common Stock issued upon repurchase of any Security declared prior to the Repurchase Date.

(e) No fractions of shares of Common Stock shall be issued upon repurchase of any Security or Securities in the event of a repurchase upon the occurrence of a Fundamental Change. If more than one Security shall be repurchased from the same Holder and any portion of the Repurchase Price payable in the event of a repurchase upon the occurrence of a Fundamental Change shall be payable in shares of Common Stock, the number of full shares which shall be issued upon such repurchase shall be computed on the basis of the aggregate principal amount of the Securities (or specified portions thereof) to be so repurchased. Instead of any fractional share of Common Stock which would otherwise be issued on the repurchase of any Security or Securities (or specified portions thereof), the Company shall pay a cash adjustment in respect of such fraction (calculated to the nearest one-100^th of a share) in an amount equal to the same fraction of the Trading Price of the Common Stock as of the Trading Day preceding the Repurchase Date.

(f) Any issuance and delivery of stock certificates representing shares of Common Stock on repurchase of Securities shall be made without charge to the Holder of Securities being repurchased for such stock certificates or for any tax or duty in respect of the issuance or delivery of such stock certificates or the Securities represented thereby; provided, however, that the Company shall not be required to pay any tax or duty which may be payable in respect of (i) income of the Holder or (ii) any transfer involved in the issuance or delivery of stock certificates representing shares of Common Stock in a name other than that of the Holder of the Securities being repurchased, and no such issuance or delivery shall be made unless the Person requesting such issuance or delivery has paid to the Company the amount of any such tax or duty or has established, to the satisfaction of the Company, that such tax or duty has been paid.

(g) All Securities delivered for repurchase shall be delivered to the Trustee to be canceled at the direction of the Trustee, which shall dispose of the same as provided in Section 2.15.

Section 11.7 Covenant to Comply with Securities Laws upon Repurchase of Securities.

When complying with the provisions of this Article 11 (provided that such offer or purchase 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), the Company shall (a) comply with Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act which may then be applicable, (b) file the related Schedule TO (or any successor schedule, form or report) under the Exchange Act and (c) otherwise comply with all federal and state securities laws so as to permit the rights and obligations under this Article 11 to be exercised in the time and in the manner specified in this Article 11.

Subject to and upon compliance with the provisions of this Article, at the option of the Holder thereof, any Security or any portion of the principal amount thereof which is an integral multiple of $1,000 may be converted at the principal amount thereof, or of such portion thereof, into duly authorized, fully paid and nonassessable shares of Common Stock, at the Conversion Price, determined as hereinafter provided, in effect at the time of conversion. Such conversion right shall expire at the close of business on the Business Day immediately preceding October 1, 2024.

In case a Security or portion thereof is called for redemption, such conversion right in respect of the Security or the portion so called, shall expire at the close of business on the second Business Day preceding the Redemption Date, unless the Company defaults in making the payment due upon redemption. In the case of a Fundamental Change for which the Holder exercises its Repurchase Right with respect to a Security or portion thereof, such conversion right in respect of the Security or portion thereof shall expire at the close of business on the Business Day immediately preceding the Repurchase Date.

The price at which shares of Common Stock shall be delivered upon conversion (the “Conversion Price”) shall be initially equal to $3.92 per share of Common Stock. The Conversion Price shall be adjusted in certain instances as provided in paragraphs (a), (b), (c), (d), (e), (f), (h) and (1) of Section 12.4.

To exercise the conversion right, the Holder of any Security to be converted shall surrender such Security duly endorsed or assigned to the Company or in blank, at the office of any Conversion Agent, accompanied by a duly signed conversion notice substantially in the form attached to the Security, to the Company, with a copy to the Trustee, stating that the Holder elects to convert such Security or, if less than the entire principal amount thereof is to be converted, the portion thereof to be converted.

Securities surrendered for conversion during the period from the close of business on any Regular Record Date to the opening of business on the next succeeding Interest Payment Date (except in the case of any Security whose Maturity is prior to such Interest Payment Date) shall be accompanied by payment in New York Clearing House funds or other funds acceptable to the Company of an amount equal to the interest to be received on such Interest Payment Date on the principal amount of Securities being surrendered for conversion.

Securities shall be deemed to have been converted immediately prior to the close of business on the day of surrender of such Securities for conversion in accordance with the provisions of this Article 12, including any required payments, and at such time the rights of the Holders of such Securities as Holders shall cease, and the Person or Persons entitled to receive the Common Stock issuable upon conversion shall be treated for all purposes as the record holder or holders of such Common Stock at such time. As promptly as practicable on or after the conversion date, the Company shall cause to be issued and delivered to such Conversion Agent a stock certificate or stock certificates representing the number of full shares of Common Stock issuable upon conversion of such Securities, together with payment in lieu of any fraction of a share as provided in Section 12.3.

In the case of any Security which is converted in part only, upon such conversion the Company shall execute and the Trustee shall authenticate and deliver to the Holder thereof, at the expense of the Company, a new Security or Securities of authorized denominations in aggregate principal amount equal to the unconverted portion of the principal amount of such Securities.

If shares of Common Stock to be issued upon conversion of a Restricted Security, or Securities to be issued upon conversion of a Restricted Security in part only, are to be registered in a name other than that of the Holder of such Restricted Security, such Holder must deliver to the Conversion Agent a certificate in substantially the form set forth in the form of Security set forth in Exhibit A annexed hereto, dated the date of surrender of such Restricted Security and signed by such Holder, as to compliance with the restrictions on transfer applicable to such Restricted Security. Neither the Trustee nor any Conversion Agent, Registrar or Transfer Agent shall be required to register in a name other than that of the Holder shares of Common Stock or Securities issued upon conversion of any such Restricted Security not so accompanied by a properly completed certificate.

No fractional shares of Common Stock shall be issued upon conversion of any Security or Securities. If more than one Security shall be surrendered for conversion at one time by the same Holder, the number of full shares which shall be issued upon conversion thereof shall be computed on the basis of the aggregate principal amount of the Securities (or specified portions thereof) so surrendered. Instead of any fractional share of Common Stock which would otherwise be issued upon conversion of any Security or Securities (or specified portions thereof), the Company shall pay a cash adjustment in respect of such fraction (calculated to the nearest one-100^th of a share) in an amount equal to the same fraction of the Trading Price of the Common Stock as of the Trading Day preceding the date of conversion.

The Conversion Price shall be subject to adjustment, calculated by the Company, from time to time as follows:

(a) In case the Company shall hereafter pay a dividend or make a distribution to all holders of the outstanding Common Stock in shares of Common Stock, 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 reduced 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 Record Date (as defined in Section 12.4(g)) 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 shall become effective immediately after the opening of business on the day following the Record Date. If any dividend or distribution of the type described in this Section 12.4(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 outstanding shares of Common Stock shall be subdivided into a greater number of shares of Common Stock, 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 outstanding shares of Common Stock shall be combined into a smaller number of shares of Common Stock, 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, such reduction or increase, as the case may be, to become effective immediately after the opening of business on the day following the day upon which such subdivision or combination becomes effective.

(c) In case the Company shall issue rights or warrants (other than any rights or warrants referred to in Section 12.4(d)) to all holders of its outstanding shares of Common Stock exercisable for not more than 60 days entitling them to subscribe for or purchase shares of Common Stock at a price per share less than the Current Market Price on the Record Date fixed for the determination of stockholders entitled to receive such rights or warrants, 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 after such Record Date 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 Record Date, plus the number of shares which the aggregate offering price of the total number of shares so offered for subscription or purchase (or the aggregate conversion price of the convertible securities so offered) would purchase at such Current Market Price; and

(ii) the denominator of which shall be the number of shares of Common Stock outstanding on the close of business on the Record Date, plus the total number of additional shares of Common Stock so offered for subscription or purchase (or into which the convertible securities so offered are convertible).

Such adjustment shall become effective immediately after the opening of business on the day following the Record Date fixed for determination of stockholders entitled to receive such rights or warrants. To the extent that shares of Common Stock (or securities convertible into 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 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 such 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 Current Market 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, the value of such consideration if other than cash, to be determined by the Board of Directors.

Notwithstanding the foregoing, in the event that the Company shall make a distribution subject to this Section 12.4(c) the Company may, in lieu of making any adjustment required pursuant to this Section 12.4(c), make proper provision so that each holder of a Security who converts such Security (or any portion thereof) after the Record Date for such distribution shall be entitled to receive upon such conversion, in addition to the shares of Common Stock issuable upon such conversion, the securities such Holder would have received had such Holder converted such Security (or portion thereof) immediately prior to such Record Date.

(d) In case the Company shall, 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 12.4(a) applies) or evidences of its indebtedness, cash or other assets, including securities, but excluding (1) any rights or warrants referred to in Section 12.4(c), (2) any stock, securities or other property or assets (including cash) distributed in connection with a reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance to which Section 12.11 applies and (3) dividends and distributions paid exclusively in cash (the securities described in foregoing clauses (1), (2) and (3) hereinafter in this Section 12.4(d) called the “securities”), then, in each such case, subject to the second succeeding paragraph of this Section 12.4(d), the Conversion Price shall be reduced so that the same shall be

equal to the price determined by multiplying the Conversion Price in effect immediately prior to the close of business on the Record Date with respect to such distribution by a fraction:

(i) the numerator of which shall be the Current Market Price on such date, less the fair market value (as determined by the Board of Directors, whose determination shall be conclusive and set forth in a Board Resolution) on such date of the portion of the securities so distributed applicable to one share of Common Stock (determined on the basis of the number of shares of the Common Stock outstanding on the Record Date); and

Such reduction shall become effective immediately prior to the opening of business on the day following the Record Date. However, in the event that (x) the then fair market value (as so determined) of the portion of the securities so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price on the Record Date or (y) the Current Market Price on the Record Date exceeds the fair market value of such distribution by less than $1.00, then, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder shall have the right to receive upon conversion of a Security (or any portion thereof) the amount of securities such Holder would have received had such Holder converted such Security (or portion thereof) immediately prior to such Record Date. In the event that such dividend or distribution is not so paid or made, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such dividend or distribution had not been declared.

If the Board of Directors determines the fair market value of any distribution for purposes of this Section 12.4(d) by reference to the actual or when issued trading market for any securities comprising all or part of such distribution, it must in doing so consider the prices in such market over the same period (the “Reference Period”) used in computing the Current Market Price pursuant to Section 12.4(g) to the extent possible, unless the Board of Directors in a Board Resolution determines in good faith that determining the fair market value during the Reference Period would not be in the best interest of the Holders.

Notwithstanding the foregoing, in the event that the Company shall make a distribution subject to this Section 12.4(d) the Company may, in lieu of making any adjustment required pursuant to this Section 12.4(d), make proper provision so that each holder of a Security who converts such Security (or any portion thereof) after the Record Date for such distribution shall be entitled to receive upon such conversion, in addition to the shares of Common Stock issuable upon such conversion, the securities such Holder would have received had such Holder converted such Security (or portion thereof) immediately prior to such Record Date.

Rights or warrants distributed by the Company to all holders of Common Stock entitling the holders thereof 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”):

shall be deemed not to have been distributed for purposes of this Section 12.4(d) (and no adjustment to the Conversion Price under this Section 12.4(d) will be required) until the occurrence of the earliest Trigger Event. If such right or warrant is subject to subsequent events, upon the occurrence of which such right or warrant shall become exercisable to purchase different securities, evidences of indebtedness or other assets or entitle the holder to purchase a different number or amount of the foregoing or to purchase any of the foregoing at a different purchase price, then the occurrence of each such event shall be deemed to be the date of issuance and record date with respect to a new right or warrant (and a termination or expiration of the existing right or warrant without exercise by the holder 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 resulted in an adjustment to the Conversion Price under this Section 12.4(d):

(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 holders of Common Stock as of the date of such redemption or repurchase; and

(2) in the case of such rights or warrants all of which shall have expired or been terminated without exercise, the Conversion Price shall be readjusted as if such rights and warrants had never been issued.

For purposes of this Section 12.4(d) and Sections 12.4(a), 12.4(b) and 12.4(c), any dividend or distribution to which this Section 12.4(d) is applicable that also includes shares of Common Stock, a subdivision or combination of Common Stock to which Section 12.4(c) applies, or rights or warrants to subscribe for or purchase shares of Common Stock to which Section 12.4(c) applies (or any combination thereof), shall be deemed instead to be:

(1) 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 subdivision or combination or such rights or warrants to which Sections 12.4(a), 12.4(b) and 12.4(c) apply, respectively (and any Conversion Price reduction required by this Section 12.4(d) with respect to such dividend or distribution shall then be made), immediately followed by

(2) a dividend or distribution of such shares of Common Stock, such subdivision or combination or such rights or warrants (and any further Conversion Price reduction required by Sections 12.4(a), 12.4(b) and 12.4(c) with respect to such dividend or distribution shall then be made), except:

(A) the Record Date of such dividend or distribution shall be substituted as (x) “the date fixed for the determination of stockholders entitled to receive such dividend or other distribution,” “Record Date fixed for such determinations” and “Record Date” within the meaning of Section 12.4(a), (y) “the day upon which such subdivision becomes effective” and “the day upon which such combination becomes effective” within the meaning of

Section 12.4(b), and (z) as “the date fixed for the determination of stockholders entitled to receive such rights or warrants,” “the Record Date fixed for the determination of the stockholders entitled to receive such rights or warrants” and such “Record Date” within the meaning of Section 12.4(c); and

(B) 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 12.4(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, by dividend or otherwise, distribute to all or substantially all holders of its Common Stock cash (excluding any cash that is distributed upon a reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance to which Section 12.11 applies or as part of a distribution referred to in Section 12.4(d)), then, and in each such case, immediately after the close of business on such date, the Conversion Price shall be reduced so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the close of business on such Record Date by a fraction:

(i) the numerator of which shall be equal to the Current Market Price on the Record Date less an amount equal to the quotient of (x) the amount of such distribution and (y) the number of shares of Common Stock outstanding on the Record Date, and

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

In the event that such dividend or distribution is not so paid or made, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such dividend or distribution had not been declared.

(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 determination shall be conclusive and set forth in a Board Resolution) that combined together with:

(1) the aggregate of the cash plus the fair market value (as determined by the Board of Directors, whose determination shall be conclusive and set forth in a Board Resolution), as of the expiration of such tender offer, of 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 12.4(f) has been made;

(2) the aggregate amount of any distributions to all holders of the Company’s Common Stock made exclusively in cash within 12 months preceding the expiration of such tender offer and in respect of which no adjustment pursuant to Section 12.4(e) has been made; and

exceeds 10% of the product of the Current Market Price 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) on 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:

(i) the numerator of which shall be the number of shares of Common Stock outstanding (including any tendered shares) at the Expiration Time multiplied by the Current Market Price of the Common Stock on the Trading Day next succeeding the Expiration Time; and

(ii) the denominator 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) on 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 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 12.4(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 12.4(f).

(g) For purposes of this Section 12.4, the following terms shall have the meanings indicated:

(1) “Current Market Price” shall mean the average of the daily Trading Prices per share of Common Stock for the ten consecutive Trading Days immediately prior to the date in question; provided, however, that if:

(i) the “ex” date (as hereinafter defined) for any event (other than the issuance or distribution requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 12.4(a), (b), (c), (d), (e) or (f) occurs during such ten consecutive Trading Days, the Trading Price for each Trading Day prior to the “ex” date for such other event shall be adjusted by multiplying such Trading Price by the same fraction by which the Conversion Price is so required to be adjusted as a result of such other event;

(ii) the “ex” date for any event (other than the issuance or distribution requiring such computation) that requires an adjustment to the

Conversion Price pursuant to Section 12.4(a), (b), (c), (d), (e) or (f) occurs on or after the “ex” date for the issuance or distribution requiring such computation and prior to the day in question, the Trading Price for each Trading Day on and after the “ex” date for such other event shall be adjusted by multiplying such Trading Price by the reciprocal of the fraction by which the Conversion Price is so required to be adjusted as a result of such other event; and

(iii) the “ex” date for the issuance or distribution requiring such computation is prior to the day in question, after taking into account any adjustment required pursuant to clause (i) or (ii) of this proviso, the Trading Price for each Trading Day on or after such “ex” date shall be adjusted by adding thereto the amount of any cash and the fair market value (as determined by the Board of Directors in a manner consistent with any determination of such value for purposes of Section 12.4(d) or (f), whose determination shall be conclusive and set forth in a Board Resolution) of the evidences of indebtedness, shares of capital stock or assets being distributed applicable to one share of Common Stock as of the close of business on the day before such “ex” date.

For purposes of any computation under Section 12.4(f), the Current Market Price of the Common Stock on any date shall be deemed to be the average of the daily Trading Prices per share of Common Stock for such day and the next two succeeding Trading Days; provided, however, that if the “ex” date for any event (other than the tender offer requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 12.4(a), (b), (c), (d), (e) or (f) occurs on or after the Expiration Time for the tender or exchange offer requiring such computation and prior to the day in question, the Trading Price for each Trading Day on and after the “ex” date for such other event shall be adjusted by multiplying such Trading Price by the reciprocal of the fraction by which the Conversion Price is so required to be adjusted as a result of such other event. For purposes of this paragraph, the term “ex” date, when used:

(A) with respect to any issuance or distribution, means the first date on which the Common Stock trades regular way on the relevant exchange or in the relevant market from which the Trading Price was obtained without the right to receive such issuance or distribution;

(B) with respect to any subdivision or combination of shares of Common Stock, means the first date on which the Common Stock trades regular way on such exchange or in such market after the time at which such subdivision or combination becomes effective; and

(C) with respect to any tender or exchange offer, means the first date on which the Common Stock trades regular way on such exchange or in such market after the Expiration Time of such offer.

Notwithstanding the foregoing, whenever successive adjustments to the Conversion Price are called for pursuant to this Section 12.4, such adjustments shall be made to the Current Market Price as may be necessary or appropriate to effectuate the intent of this Section 12.4 and to avoid unjust or inequitable results as determined in good faith by the Board of Directors.

(2) “fair market value” shall mean the amount which a willing buyer would pay a willing seller in an arm’s length transaction which, in the absence of a current market for such transaction, shall be determined in good faith by the Board of Directors.

(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 reductions in the Conversion Price, in addition to those required by Sections 12.4(a), (b), (c), (d), (e) or (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.

To the extent permitted by applicable law, the Company from time to time may reduce the Conversion Price by any amount for any period of time if the period is at least 20 days and the reduction is irrevocable during the period and the Board of Directors determines in good faith that such reduction would be in the best interests of the Company, which determination shall be conclusive and set forth in a Board Resolution; provided, however, that the Board of Directors shall not be permitted to reduce the Conversion Price pursuant to this sentence in such a manner that will violate NASD Rule 4350(i) or any similar or successor rule then in effect. Whenever the Conversion Price is reduced pursuant to the preceding sentence, the Company shall mail to the Trustee and each Holder at the address of such Holder as it appears in the Register a notice of the reduction at least 15 days prior to the date the reduced Conversion Price takes effect, and such notice shall state the reduced Conversion Price and the period during which it will be in effect.

(i) 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 12.4(i) are not required to be made shall be carried forward and taken into account (A) in any subsequent adjustment; (B) if and when the Company has called the Securities for redemption pursuant to Article 10 or (C) on the Maturity Date. All calculations under this Article 12 shall be made by the Company and shall be made to the nearest cent or to the nearest one-100^th of a share, as the case may be. No adjustment need be made for a change in the par value or no par value of the Common Stock.

(j) In any case in which this Section 12.4 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 Security 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 12.3.

(k) For purposes of this Section 12.4, 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. The Company will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company.

(l) If the distribution date for the rights provided in the Company’s rights agreement, if any, occurs prior to the date a Security is converted, and the Holder of the Security who converts such Security after the distribution date is not entitled to receive the rights that would otherwise be attached (but for the date of conversion) to the shares of Common Stock received upon such conversion, then an adjustment shall be made to the Conversion Price pursuant to Section 12.4(b) as if the rights were being distributed to the holders of Common Stock immediately prior to such conversion. If such an adjustment is made and the rights are later redeemed, invalidated or terminated, then a corresponding reversing adjustment shall be made to the Conversion Price, on an equitable basis, to take account of such event.

Whenever the Conversion Price is adjusted as herein provided (other than in the case of an adjustment pursuant to the second paragraph of Section 12.4(h) for which the notice required by such paragraph has been provided), the Company shall promptly file with the Trustee and any Conversion Agent other than the Trustee an Officers’ Certificate setting forth the adjusted Conversion Price and showing in reasonable detail the facts upon which such adjustment is based. The Company shall also issue a press release through Dow Jones & Company, Inc, Business Wire or Bloomberg Business News (or, if such organizations are not in existence at the time of issuance of such press release, such other news or press organization as is reasonably calculated to broadly disseminate the relevant information to the public) containing the relevant information and make such information available on the Company’s web site or through another public medium as the Company may use at such time. Unless and until the Trustee and any Conversion Agent other than the Trustee receive an Officer’s Certificate setting forth an adjustment to the Conversion Price, the Trustee and such Conversion Agent may assume without inquiry that the Conversion Price has not and is not required to be adjusted and that the last Conversion Price of which the Trustee and such Conversion Agent have knowledge remains in effect. Promptly after delivery of such Officers’ Certificate, the Company shall prepare a notice stating that the Conversion Price has been adjusted and setting forth the adjusted Conversion Price and the date on which each adjustment becomes effective, and shall mail such notice to each Holder at the address of such Holder as it appears in the Register within 20 days of the effective date of such adjustment. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

(1) the Company shall declare a dividend (or any other distribution) on its Common Stock payable otherwise than in cash out of its capital surplus or its consolidated retained earnings;

(2) the Company shall authorize the granting to the holders of its Common Stock of rights or warrants to subscribe for or purchase any shares of capital stock of any class (or of securities convertible into shares of capital stock of any class) or of any other rights;

(3) there shall occur any reclassification of the Common Stock of the Company (other than a subdivision or combination of its outstanding Common Stock, a change in par value, a change from par

value to no par value or a change from no par value to par value), or any merger, consolidation, statutory share exchange or combination to which the Company is a party and for which approval of any shareholders of the Company is required, or the sale, transfer or conveyance of all or substantially all of the assets of the Company; or

(4) there shall occur the voluntary or involuntary dissolution, liquidation or winding up of the Company;

the Company shall cause to be filed at each office or agency maintained for the purpose of conversion of securities pursuant to Section 9.2, and shall cause to be provided to the Trustee and all Holders in accordance with Section 15.2, at least 20 days (or 10 days in any case specified in clause (1) or (2) above) prior to the applicable record or effective date hereinafter specified, a notice stating:

(A) the date on which a record is to be taken for the purpose of such dividend, distribution, 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, rights or warrants are to be determined; or

(B) the date on which such reclassification, merger, consolidation, statutory share exchange, combination, sale, transfer, conveyance, dissolution, liquidation or winding up is expected to become effective, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities, cash or other property deliverable upon such reclassification, merger, consolidation, statutory share exchange, sale, transfer, dissolution, liquidation or winding up.

Neither the failure to give such notice nor any defect therein shall affect the legality or validity of the proceedings or actions described in clauses (1) through (4) of this Section 12.6.

The Company shall at all times use its best efforts to reserve and keep available, free from preemptive rights, out of its authorized but unissued Common Stock, for the purpose of effecting the conversion of Securities, the full number of shares of fully paid and nonassessable Common Stock then issuable upon the conversion of all Outstanding Securities.

Except as provided in the next sentence, the Company will pay any and all taxes (other than taxes on income) and duties that may be payable in respect of the issue or delivery of shares of Common Stock on conversion of Securities pursuant hereto. A Holder delivering a Security for conversion shall be liable for and will be required to pay any tax or duty which may be payable in respect of any transfer involved in the issue and delivery of shares of Common Stock in a name other than that of the Holder of the Security or Securities to be converted, and no such issue or delivery shall be made unless the Person requesting such issue has paid to the Company the amount of any such tax or duty, or has established to the satisfaction of the Company that such tax or duty has been paid.

The Company covenants that all shares of Common Stock which may be issued upon conversion of Securities will upon issuance be fully paid and nonassessable and that the Company will pay all taxes, liens and charges with respect to the issuance thereof, except (1) as provided in Section 12.8 or (2) with respect to any liens or charges created by or imposed upon such Common Stock by the Holder of the Security or Securities to be converted.

All Securities delivered for conversion shall be delivered to the Trustee to be canceled by or at the direction of the Trustee, which shall dispose of the same as provided in Section 2.15.

(i) any reclassification or change of the outstanding shares of Common Stock (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination);

(ii) any merger, consolidation, statutory share exchange or combination of the Company with another corporation 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; or

(iii) any sale or conveyance of the properties and assets of the Company as, or substantially as, an entirety to any other corporation 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;

the Company or the successor or purchasing corporation, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the TIA as in force at the date of execution of such supplemental indenture if such supplemental indenture is then required to so comply) providing that such Security shall be convertible into the kind and amount of shares of stock and other securities or property or assets (including cash) which such Holder would have been entitled to receive upon such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance had such Securities been converted into Common Stock immediately prior to such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance assuming such holder of Common Stock did not exercise its rights of election, if any, as to the kind or amount of securities, cash or other property receivable upon such merger, consolidation, statutory share exchange, sale or conveyance (provided, that if the kind or amount of securities, cash or other property receivable upon such merger, consolidation, statutory share exchange, 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 (“Non-Electing Share”), then for the purposes of this Section 12.11 the kind and amount of securities, cash or other property receivable upon such merger, consolidation, statutory share exchange, 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 12. If, in the case of any such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance, the stock or other securities and assets receivable thereupon by a holder of shares of Common Stock includes shares of stock or other securities and assets of a corporation other than the successor or purchasing corporation, as the case may be, in such reclassification, change, merger, consolidation, statutory share exchange, 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, including to the extent practicable the provisions providing for the Repurchase Rights set forth in Article 11.

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, 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, mergers, consolidations, statutory share exchanges, combinations, sales and conveyances.

If this Section 12.11 applies to any event or occurrence, Section 12.4 shall not apply.

(a) Subject to the Company’s right to irrevocably elect to make a cash payment of principal upon conversion pursuant to Section 12.12(f), in lieu of delivery of shares of Common Stock in satisfaction of its obligation upon conversion of Securities, the Company may elect to deliver cash or a combination of cash and shares of Common Stock. Except to the extent that the Company has irrevocably elected to make a cash payment of principal upon conversion pursuant to Section 12.12(f), the Company shall inform the Holders through the Trustee of the method it elects to satisfy its obligation upon conversion:

(1) if the Company has called the Securities for redemption pursuant to Article 10, in its notice of redemption;

(2) in respect of Securities to be converted during the period beginning 25 Trading Days preceding the Maturity Date and ending one Trading Day preceding the Maturity Date, 26 Trading Days preceding the Maturity Date; and

(3) in all other cases, no later than two Trading Days following the conversion date.

(b) If the Company elects to satisfy any portion of its conversion obligation in cash, the Company shall specify the amount to be satisfied in cash as a percentage of the conversion obligation or a fixed dollar amount. The Company shall treat all Holders converting on the same Trading Day in the same manner. The Company shall not, however, have any obligation to settle its conversion obligations arising on different Trading Days in the same manner.

(c) If the Company elects to satisfy any portion of its conversion obligation in cash (other than cash in lieu of fractional shares), a Holder may retract its conversion notices at any time during the two Trading Day period beginning on the Trading Day after the Company has notified the Trustee of its method of settlement (such period, the “Conversion Retraction Period”). However, a Holder shall not be permitted to retract its conversion notice if:

(1) the Company has irrevocably elected to make a cash payment of principal upon conversion before such Holder delivered its conversion notice;

(2) such Holder is converting its Securities in connection with a redemption pursuant to Article 10;

(3) such Holder is converting its Securities during the period beginning 25 Trading Days preceding the Maturity Date and ending one Trading Day preceding the Maturity Date; or

(4) the Company not elect to satisfy any portion of its conversion obligation in cash.

(d) Settlement in shares of our Common Stock shall occur as soon as practicable after the Company has notified the Holders that it has elected this method of settlement. Settlement in cash or in a combination of cash and shares of Common Stock shall occur on the second Trading Day following the final Trading Day (the “Determination Date”) of the Cash Settlement Averaging Period. The Determination Date shall be the 26^th Trading Day following the Company’s receipt of a Holder’s conversion notice (if such Holder does not retract its conversion notice and has satisfied all other conversion requirements), unless conversion is:

(1) in connection with a redemption pursuant to Article 10, in which case the Determination Date shall be the Redemption Date;

(2) subject to the succeeding clause (3), after the Company has irrevocably elected to make a cash payment of principal upon conversion, in which case the Determination Date shall be the 22^ndTrading Day following the Company’s receipt of such Holder’s conversion notice; or

(3) during the period beginning 25 Trading Days preceding the Maturity Date and ending one Trading Day preceding the Maturity Date, in which case the Determination Date shall be the Maturity Date.

(1) If the Company elects to satisfy the entire conversion obligation in shares of Common Stock, the Company shall deliver to the Holder a number of shares of Common stock equal to (i) the aggregate principal amount of Securities to be converted divided by (ii) the Conversion Price then in effect (substituting cash in lieu of fractional shares).

(2) If the Company elects to satisfy the entire conversion obligation in cash, the Company shall deliver to the Holder cash in an amount (the “Cash-Only Settlement Amount”) equal to the product of:

(A) a number equal to (i) the aggregate principal amount of Securities to be converted divided by (ii) the Conversion Price then in effect; and

(3) If the Company elects to satisfy the conversion obligation in a combination of cash and shares of Common Stock, the Company shall deliver to the Holder:

(A) (i) the fixed dollar amount per $1,000 principal amount of Securities specified in the notice regarding the Company’s chosen method of

settlement multiplied by the quotient of the aggregate principal amount of Securities to be converted divided by 1,000 or (ii) the percentage of the conversion obligation specified in the notice regarding the Company’s chosen method of settlement multiplied by the amount of cash that would be paid pursuant to clause (2) above, as the case may be (the “Cash Amount”); and

(B) a number of shares equal to (i) the Cash-Only Settlement Amount minus the Cash Amount divided by (ii) the Applicable Stock Price (substituting cash in lieu of fractional shares).

The “Applicable Stock Price” means, in respect of a Determination Date, the average Closing Sale Price (as defined below) of the Common Stock over the 20 Trading Day period (the “Cash Settlement Averaging Period”):

(i) ending on the second Trading Day preceding the Redemption Date, if the Company has called the Securities for redemption pursuant to Article 10;

(ii) subject to the succeeding clause (iii), beginning on the Trading Day following the Company’s receipt of the Holder’s conversion notice, if the Company has irrevocably elected to make a cash payment of principal upon conversion;

(iii) ending on the second Trading Day preceding the Maturity Date, with respect to conversion notices received during the period beginning 25 Trading Days preceding the Maturity Date and ending one Trading Day preceding the Maturity Date; and

(iv) beginning on the Trading Day following the final Trading Day of the Conversion Retraction Period, in all other cases.

The “Closing Sale Price” of any share of Common Stock on any Trading Day means the closing sale price of such security (or if no closing sale price is reported, the average of the closing bid and closing ask prices or, if more than one in either case, the average of the average closing bid and the average closing ask prices) on such date as reported in composite transactions for the principal United States securities exchange on which the Common Stock is traded or, if the Common Stock is not listed on a United States national or regional securities exchange, as reported by the Nasdaq System or by the National Quotation Bureau Incorporated. In the absence of such a quotation, the Company shall determine the Closing Sale Price on the basis it considers appropriate.

(f) At any time on or prior to the 26th Trading Day preceding the Maturity Date, the Company may irrevocably elect to satisfy in cash its conversion obligation with respect to the principal amount of the Securities to be converted after the date of such election, with any remaining amount to be satisfied in shares of Common Stock. Such election shall be in the Company’s sole discretion without the consent of the Holders. If the Company makes such election, the Company shall notify the Trustee and the Holders at their addresses shown in the Register kept by the Registrar.

If the Company irrevocably elects to pay the principal amount of the Securities in cash upon conversion, the settlement amount shall be computed as follows:

(1) a cash amount equal to the lesser of (i) the aggregate principal amount of Securities to be converted and (ii) the Cash-Only Settlement Amount; and

(2) if the Cash-Only Settlement Amount exceeds the aggregate principal amount of Securities to be converted, a number of shares of Common Stock equal to (i) the Cash-Only Settlement Amount minus the aggregate principal amount of Securities to be converted divided by (ii) the Applicable Stock Price.

The Trustee, subject to the provisions of Section 5.1, and any Conversion Agent shall not at any time be under any duty or responsibility to any Holder of Securities to determine whether any facts exist which may require any adjustment of the Conversion Price, or with respect to the nature or intent of any such adjustments when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. Neither the Trustee, subject to the provisions of Section 5.1, nor any Conversion Agent shall be accountable with respect to the validity or value (of the kind or amount) of any Common Stock, or of any other securities or property, which may at any time be issued or delivered upon the conversion of any Security; and it or they do not make any representation with respect thereto. Neither the Trustee, subject to the provisions of Section 5.1, nor any Conversion Agent shall be responsible for any failure of the Company to make any cash payment or to issue, transfer or deliver any shares of stock or share certificates or other securities or property upon the surrender of any Security for the purpose of conversion; and the Trustee, subject to the provisions of Section 5.1, and any Conversion Agent shall not be responsible or liable for any failure of the Company to comply with any of the covenants of the Company contained in this Article.

(a) If a Fundamental Change occurs prior to October 1, 2009, the Company shall pay the Make-Whole Premium, if any, to Holders of the Securities who surrender their Securities for repurchase in connection with such Fundamental Change pursuant to Section 11.1(b) or convert their Securities pursuant to the Fundamental Change. The Make-Whole Premium, if any, shall be paid on the Fundamental Change Repurchase Date to Holders who exercise such repurchase right or conversion right.

(i) If the Effective Date is on or after October 1, 2009, no Make-Whole Premium shall be paid;

(ii) If the Stock Price is less than or equal to $2.90 (subject to adjustment pursuant to Section 13.2) (the “Stock Price Threshold”), no Make-Whole Premium shall be paid;

(iii) If the Stock Price exceeds $9.66 (subject to adjustment pursuant to Section 13.2) (the “Stock Price Cap”), no Make-Whole Premium shall be paid; and

(iv) In all other cases, the Make-Whole Premium shall be equal to a percentage (the “Additional Premium”) of the principal amount of the Securities as described in Section 13.1(c)(iii) below.

(i) “Effective Date” means the date that a Fundamental Change becomes effective.

(ii) “Stock Price” means the price paid per share of Common Stock in the transaction constituting the Fundamental Change, determined as follows:

(A) If holders of the Common Stock receive only cash in the transaction constituting the Fundamental Change, the Stock Price shall equal the cash amount paid per share of Common Stock; and

(B) In all other cases, the Stock Price shall be the average of the daily Trading Prices per share of Common Stock for the ten consecutive Trading Day period ending on the Trading Day immediately preceding the Effective Date.

(iii) “Make-Whole Percentage” means the percentage set forth on the table below (the “Make-Whole Table”) for the Stock Price and the Effective Date.

The following table illustrates what the Additional Premiums would be for various Stock Prices.

The exact Stock Price and Effective Date may not be set forth on the table. In such event if the Stock Price is between two Stock Prices on the table or the Effective Date is between two dates on the table, the Additional Premium will be determined by straight-line interpolation between Additional Premium amounts set forth for the higher and lower Stock Prices and the two dates, as applicable, based on a 365-day year.

(d) The Company will pay the Make-Whole Premium in the same form of consideration into which the Common Stock has been converted or exchanged in connection with the Fundamental Change. If holders of the Common Stock have the right to elect the form of consideration received in the transaction constituting a Fundamental Change, then for purposes of determining the form of consideration to be delivered in respect of the Make-Whole Premium, the consideration into which a share of Common Stock has been converted or exchanged shall be deemed to equal, in both form and amount, the aggregate consideration distributed in respect of all shares of Common Stock divided by the total number of shares of Common Stock participating in the distribution.

(e) For purposes of determining the value of the consideration to be issued in respect of the Make-Whole Premium, the value will be calculated as follows:

(i) securities that are traded on a United States national securities exchange or approved for quotation on the Nasdaq National Market or any similar system of automated dissemination of quotations of securities prices will be valued based on the average Closing Sale Price or last sale price, as applicable, over the ten Trading Day period ending on the Trading Day preceding the Fundamental Change Repurchase Date;

(ii) other securities, assets or property (other than cash) which holders will have the right to receive will be valued based on 98% of the average of the fair market value of such securities, assets or property (other than cash) as determined by two independent nationally recognized investment banks selected by the Trustee; and

A calculation agent (the “Calculation Agent”) appointed from time to time by the Company shall, on behalf of and on request by the Company or the Trustee, calculate (A) the Stock Price and (B) the Make-Whole Premium with respect to such Stock Price, based on the Effective Date specified by the Company or the Trustee, and shall deliver its calculation of the Stock Price and Make-Whole Premium to the Company and the Trustee within three Business Days of the request by the Company or the Trustee. In addition, the Calculation Agent shall, on behalf of and upon request by the Company or the Trustee no less than three Business Days prior to a Fundamental Change Repurchase Date, make the determinations described in Section 13.1(e)(i) above and deliver its calculations to the Company or the Trustee by 9 p.m. (New York City time) on the Trading Day preceding the Fundamental Change Repurchase Date. The Company, or at the Company’s request, the Trustee in the name and at the expense of the Company, (X) shall notify the Holders of the Stock Price and Make-Whole Premium per $1,000 original principal amount of Securities with respect to a Fundamental Change as part of the Repurchase Event Purchase Notice delivered in connection with the Fundamental Change and (Y) shall notify the Holders promptly by 9 a.m. (New York City time) on the Fundamental Change Repurchase Date of the number or amount of such securities, assets or property into which the shares of Common Stock have been converted or exchanged as of the Effective Date to be paid in respect of the Make-Whole Premium in connection with such Fundamental Change, in the manner provided in Section 15.2, and the Company shall also publicly announce such information and publish it on the Company’s web site. Any notice so given shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice.

On or prior to the Fundamental Change Repurchase Date, the Company will deposit with the Paying Agent a number or an amount of securities, assets or property sufficient to pay the Make-Whole Premium with respect to all the Securities to be repurchased on such date and all the Securities converted or exchanged in connection with such Fundamental Change; provided that if such payment is made on the Fundamental Change Repurchase Date, it must be received by the Paying Agent by 10:00 a.m. (New York City time) on such date.

Whenever the Conversion Price shall be adjusted from time to time by the Company pursuant to Section 12.4, the Stock Price Threshold and the Stock Price Cap shall be adjusted and each of the Stock Prices set forth in the Make-Whole Table shall be adjusted by multiplying each such amount by a fraction, the numerator of which is the Conversion Price immediately prior to such adjustment and the denominator of which is the Conversation Price as so adjusted.

The Company covenants and agrees, and each Holder of Securities, by such Holder’s acceptance thereof, likewise covenants and agrees, that the Indebtedness represented by the Securities and the payment of the principal of and premium, if any, and interest (including Additional Amounts, if any) on each and all of the Securities is hereby expressly subordinated and junior, to the extent and in the manner set forth and as set forth in this Section 14.1, in right of payment to the prior payment in full of all Senior Debt.

(a) In the event of any distribution of assets of the Company upon any dissolution, winding up, liquidation or reorganization of the Company, whether in bankruptcy, insolvency, reorganization or receivership proceedings or upon an assignment for the benefit of creditors or any other marshalling of the assets and liabilities of the Company or otherwise, the holders of all Senior Debt shall first be entitled to receive payment in cash of the full amount due thereon in respect of all principal and premium, if any, and interest (including interest accruing after the commencement of any bankruptcy proceeding, regardless of whether such interest is an allowed claim in such proceeding under such Senior Debt) before the Holders of any of the Securities are entitled to receive any payment or distribution of any character, whether in cash, securities or other property, on account of the principal of or premium, if any, or interest (including Additional Amounts, if any), if any on the Indebtedness evidenced by the Securities.

(b) In the event of and during the continuance of any default in payment of the principal of or premium, if any, or interest on, rent or other payment obligation in respect of, any Senior Debt, unless all such payments due in respect of such Senior Debt have been paid in full in cash or other payments satisfactory to the holders of Senior Debt, no payment shall be made by the Company with respect to the principal of, premium, if any, or interest (including Additional Amounts, if any) on the Securities or to acquire any of the Securities (including any redemption, conversion or cash repurchase pursuant to the exercise of the Repurchase Right). The Company shall give prompt written notice to the Trustee of any default under any Senior Debt or under any agreement pursuant to which Senior Debt may have been issued.

(c) During the continuance of any event of default with respect to any Designated Senior Debt, as such event of default is defined under any such Senior Debt or in any agreement pursuant to which any Senior Debt has been issued (other than a default in payment of the principal of or premium, if any, or interest on, rent or other payment obligation in respect of any Senior Debt), permitting the holder or holders of such Senior Debt to accelerate the maturity thereof (or in the case of any lease, permitting the landlord either to terminate the lease or to require the Company to make an irrevocable offer to terminate the lease following an event of default thereunder), no payment shall be made by the Company, directly or indirectly, with respect to principal of, premium, if any, or interest on the Securities (including any Additional Amounts, if any), including redemption, cash payment in lieu of conversion and repurchase payments, for 180 days following notice in writing (a “Payment Blockage Notice”) to the Company, from any holder or holders of such Senior Debt or their representative or representatives or the trustee or trustees under any indenture or under which any instrument evidencing any such Senior Debt may have been issued, that such an event of

default has occurred and is continuing, unless such event of default has been cured or waived or such Senior Debt has been paid in full; provided, however, that if the maturity of such Senior Debt is accelerated, no payment may be made on the Securities until such Senior Debt has been paid in full in cash or other payment satisfactory to the holders of such Senior Debt or such acceleration has been cured or waived.

For purposes of this Section 14.1(c), such Payment Blockage Notice shall be deemed to include notice of all other events of default under such indenture or instrument which are continuing at the time of the event of default specified in such Payment Blockage Notice. The provisions of this Section 14.1(c) shall apply only to one such Payment Blockage Notice given in any period of 365 days with respect to any issue of Senior Debt, and no such continuing event of default that existed or was continuing on the date of delivery of any Payment Blockage Notice shall be, or shall be made, the basis for a subsequent Payment Blockage Notice.

(d) In the event that, notwithstanding the foregoing provisions of Sections 14.1(a), 14.1(b) and 14.1(c), any payment on account of principal, premium, if any, or interest (including Additional Amounts, if any) on the Securities shall be made by or on behalf of the Company and received by the Trustee, by any Holder or by any Paying Agent (or, if the Company is acting as its own Paying Agent, money for any such payment shall be segregated and held in trust):

(i) after the occurrence of an event specified in Section 14.1(a), then, unless all Senior Debt is paid in full in cash, or provision shall be made therefor;

(ii) after the happening of an event of default of the type specified in Section 14.1(b) above, then, unless the amount of such Senior Debt then due shall have been paid in full, or provision made therefor or such event of default shall have been cured or waived; or

(iii) after the happening of an event of default of the type specified in Section 14.1(c) above and delivery of a Payment Blockage Notice, then, unless such event of default shall have been cured or waived or the 180-day period specified in Section 14.1(c) shall have expired;

such payment (subject, in each case, to the provisions of Section 14.7) shall be held in trust for the benefit of, and shall be immediately paid over to, all holders of Senior Debt or their representative or representatives or the trustee or trustees under any indenture under which any instruments evidencing any of the Senior Debt, as the case may be, may have been issued, as their interests may appear.

Subject to the payment in full of all Senior Debt to which the Indebtedness evidenced by the Securities is in the circumstances subordinated as provided in Section 14.1, the Holders of the Securities shall be subrogated to the rights of the holders of such Senior Debt to receive payments or distributions of cash, property or securities of the Company applicable to such Senior Debt until all amounts owing on the Securities shall be paid in full, and, as between the Company, its creditors other than holders of such Senior Debt, and the Holders of the Securities, no such payment or distribution made to the holders of Senior Debt by virtue of this Article which otherwise would have been made to the holders of the Securities shall be deemed to be a payment by the Company on account of such Senior Debt; provided, however, that the provisions of this Article are and are intended solely for the purpose of defining the relative rights of the Holders of the Securities, on the one hand, and the holders of Senior Debt, on the other hand.

Nothing contained in this Article or elsewhere in this Indenture or in the Securities is intended to or shall impair, as between the Company, its creditors other than the holders of Senior Debt, and the Holders of the Securities, the obligation of the Company, which is absolute and unconditional, to pay to the Holders of the Securities the principal of and premium, if any, and interest (including Additional Amounts, if any) on the Securities as and when the same shall become due and payable in accordance with their terms, or is intended to or shall affect the relative rights of the Holders of the Securities and creditors of the Company other than the holders of Senior Debt, nor shall anything contained herein or therein prevent the Trustee or the Holder of any Security from exercising all remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights, if any, under this Article of the holders of Senior Debt in respect of cash, property or securities of the Company received upon the exercise of any such remedy.

Upon the maturity of any Senior Debt by lapse of time, acceleration or otherwise, all principal of or premium, if any, or interest on, rent or other payment obligations in respect of all such matured Senior Debt shall first be paid in full, or such payment shall have been duly provided for, before any payment on account of principal, or premium, if any, or interest (including Additional Amounts, if any) is made upon the Securities.

Except as expressly provided in this Article, nothing contained in this Article shall affect the obligation of the Company to make, or prevent the Company from making, payments of the principal of, or premium, if any, or interest (including Additional Amounts, if any) on the Securities in accordance with the provisions hereof and thereof, or shall prevent the Trustee or any Paying Agent from applying any monies deposited with it hereunder to the payment of the principal of, or premium, if any, or interest (including Additional Amounts, if any) on the Securities.

Each Holder of Securities, by such Holder’s acceptance thereof, authorizes and directs the Trustee on such Holder’s behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in this Article and appoints the Trustee such Holder’s attorney-in-fact for any and all such purposes.

Upon any payment or distribution of assets of the Company referred to in this Article, the Trustee and the Holders of the Securities shall be entitled to rely upon any order or decree made by any court of competent jurisdiction in which any such dissolution, winding up, liquidation or reorganization proceeding affecting the affairs of the Company is pending or upon a certificate of the trustee in bankruptcy, receiver, assignee for the benefit of creditors, liquidating trustee or agent or other Person making any payment or distribution, delivered to the Trustee or to the Holders of the Securities, for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, and as to other facts pertinent to the right of such Persons under this Article, and if such evidence is not furnished, the Trustee may defer any payment to such Persons pending judicial determination as to the right of such Persons to receive such payment.

Notwithstanding the provision of this Article or any other provisions of this Indenture, the Trustee shall not be charged with knowledge of the existence of any Senior Debt, of any default in payment of principal of, premium, if any, or interest on, rent or other payment obligation in respect of any Senior Debt, or of any facts which would prohibit the making of any payment of monies to or by the Trustee, or the taking of any other action by the Trustee, unless a Responsible Officer of the Trustee having responsibility for the administration of the trust established by this Indenture shall have received written notice thereof from the Company, any Holder of Securities, any Paying Agent or Conversion Agent of the Company or the holder or representative of any class of Senior Debt, and, prior to the receipt of any such written notice, the Trustee shall be entitled in all respects to assume that no such default or facts exist; provided, however, that unless on the third Business Day prior to the date upon which by the terms hereof any such monies may become payable for any purpose the Trustee shall have received the notice provided for in this Section 14.7, then, anything herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such monies and apply the same to the purpose for which they were received, and shall not be affected by any notice to the contrary which may be received by it on or after such date.

The Trustee shall be entitled to all the rights set forth in this Article with respect to any Senior Debt at the time held by it, to the same extent as any other holder of Senior Debt and nothing in this Indenture shall deprive the Trustee of any of its rights as such holder.

Nothing contained in this Article shall apply to claims of or payments to the Trustee under or pursuant to Section 5.8.

With respect to the holders of Senior Debt, the Trustee undertakes to perform or to observe only such of its covenants and obligations as are specifically set forth in this Article, and no implied covenants or obligations with respect to the holders of Senior Debt shall be read into this Indenture against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Debt and the Trustee shall not be liable to any holder of Senior Debt if it shall pay over or deliver to Holders, the Company or any other Person monies or assets to which any holder of Senior Debt shall be entitled by virtue of this Article or otherwise.

No right of any present or future holder of any Senior Debt to enforce the subordination herein shall at any time or in any way be prejudiced or impaired by any act or failure to act on the part of the Company or by any noncompliance by the Company with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof any such holder may have or be otherwise charged with.

Any renewal or extension of the time of payment of any Senior Debt or the exercise by the holders of Senior Debt of any of their rights under any instrument creating or evidencing Senior Debt, including without limitation the waiver of default thereunder, may be made or done all without notice to or assent from the Holders of the Securities or the Trustee.

No compromise, alteration, amendment, modification, extension, renewal or other change of, or waiver, consent or other action in respect of, any liability or obligation under or in respect of, or of

any of the terms, covenants or conditions of any indenture or other instrument under which any Senior Debt is outstanding or of such Senior Debt, whether or not such release is in accordance with the provisions or any applicable document, shall in any way alter or affect any of the provisions of this Article or of the Securities relating to the subordination thereof.

(1) the issuance and delivery of junior securities upon (A) conversion of Securities in accordance with Article 12 or (B) repurchase of Securities in accordance with Article 11 shall not be deemed to constitute a payment or distribution on account of the principal of, premium, if any, or interest (including Additional Amounts, if any) on Securities or on account of the purchase or other acquisition of Securities; and

(2) the payment, issuance or delivery of cash (except in satisfaction of fractional shares pursuant to Section 12.3 or pursuant to Section 11.3), property or securities (other than junior securities) upon (A) conversion of a Security or (B) repurchase of Securities in accordance with Article 11 hereof shall be deemed to constitute payment on account of the principal of, premium, if any, or interest (including Additional Amounts, if any) on such Security.

Nothing contained in this Article 14 or elsewhere in this Indenture or in the Securities is intended to or shall impair, as among the Company, its creditors (other than holders of Senior Debt) and the Holders of Securities, the right, which is absolute and unconditional, of the Holder of any Security to convert such Security in accordance with Article 12.

This Indenture is subject to the provisions of the TIA which are required to be part of this Indenture, and shall, to the extent applicable, be governed by such provisions.

Any notice or communication to the Company or the Trustee is duly given if in writing and delivered in person or mailed by first-class mail to the address set forth below:

The Company or the Trustee by notice to the other may designate additional or different addresses for subsequent notices or communications.

Any notice or communication to a Holder shall be mailed by first-class mail to his address shown on the Register kept by the Registrar. Failure to mail a notice or communication to a Holder or any defect in such notice or communication shall not affect its sufficiency with respect to other Holders.

If a notice or communication is mailed or sent in the manner provided above within the time prescribed, it is duly given as of the date it is mailed, whether or not the addressee receives it, except that notice to the Trustee shall only be effective upon receipt thereof by the Trustee.

If the Company mails a notice or communication to Holders, it shall mail a copy to the Trustee at the same time.

Holders may communicate pursuant to Section 312(b) of the TIA with other Holders with respect to their rights under the Securities or this Indenture. The Company, the Trustee, the Registrar and anyone else shall have the protection of Section 312(c) of the TIA.

(a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders of Securities may be embodied in and evidenced by:

(1) one or more instruments of substantially similar tenor signed by such Holders in person or by agent or proxy duly appointed in writing;

(2) the record of Holders of Securities voting in favor thereof, either in person or by proxies duly appointed in writing, at any meeting of Holders of Securities duly called and held in accordance with the provisions of Article 8; or

Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments or record or both are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments and record (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders of Securities signing such instrument or instruments and so voting at such meeting. Proof of execution of any such instrument or of a writing appointing any such agent or proxy, or of the holding by any Person of a Security, shall be sufficient for any purpose of this Indenture and (subject to Section 5.1) conclusive in favor of the Trustee and the Company if made in the manner provided in this Section. The record of any meeting of Holders of Securities shall be proved in the manner provided in Section 8.6.

(b) The fact and date of the execution by any Person of any such instrument or writing may be provided in any manner which the Trustee reasonably deems sufficient.

(c) The principal amount and serial numbers of Securities held by any Person, and the date of such Person holding the same, shall be proved by the Register.

(d) Any request, demand, authorization, direction, notice, consent, election, waiver or other Act of the Holders of any Security shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Security.

In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents.

Any certificate or opinion of an officer of the Company may be based, insofar as it relates to legal matters, upon an Opinion of Counsel, unless such officer knows, or in the exercise of reasonable care should know, that the Opinion of Counsel with respect to the matters upon which such certificate or opinion is based is erroneous. Any such Opinion of Counsel may be based, insofar as it relates to factual matters, upon a certificate or representations by, an officer or officers of the Company stating that the information with respect to such factual matters is in the possession of the Company, unless such counsel knows, or in the exercise of reasonable care should know, that the certificate or representations with respect to such matters are erroneous.

Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument.

Upon any application or request by the Company to the Trustee to take any action under any provision of this Indenture, the Company shall furnish to the Trustee an Officers’ Certificate stating that all conditions precedent, if any, provided for in this Indenture relating to the proposed action have been complied with and an Opinion of Counsel stating that in the opinion of such Counsel all such conditions precedent, if any, have been complied with, except that in the case of any such application or request as to which the furnishing of such documents is specifically required by any provision of this Indenture relating to such particular application or request, no additional certificate or opinion need be furnished.

Each certificate or opinion with respect to compliance with a condition or covenant provided for in this Indenture shall include:

The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof.

All covenants and agreements in this Indenture by the Company shall bind its successors and assigns, whether so expressed or not.

In case any provision in this Indenture or the Securities shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

Nothing contained in this Indenture or in the Securities, express or implied, shall give to any Person, other than the parties hereto and their successors hereunder, the holders of Senior Debt and the Holders of Securities, any benefit or legal or equitable right, remedy or claim under this Indenture.

THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

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

In any case where any Interest Payment Date, Redemption Date, Repurchase Date or Stated Maturity of any Security or the last day on which a Holder of a Security has a right to convert such Security shall not be a Business Day at any Place of Payment or Place of Conversion, then (notwithstanding any other provision of this Indenture or of the Securities) payment of interest (including Additional Amounts, if any) or principal or premium, if any, or conversion of the Securities, need not be made at such Place of Payment or Place of Conversion on such day, but may be made on the next succeeding Business Day at such Place of Payment or Place of Conversion with the same force and effect as if made on the Interest Payment Date, Redemption Date, Repurchase Date or at the Stated Maturity or on such last day for conversion; provided, however, that in the case that payment is made on such succeeding Business Day, no interest shall accrue on the amount so payable for the period from and after such Interest Payment Date, Redemption Date, Repurchase Date or Stated Maturity, as the case may be.

No recourse for the payment of the principal of or premium, if any, or interest (including Additional Amounts, if any) on any Security, or for any claim based thereon or otherwise in respect thereof, shall be had against any incorporator, shareholder, officer or director, as such, past, present or future, of the Company or of any successor corporation, whether by virtue of any constitution, statute or rule of law or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance thereof and as part of the consideration for the issue thereof, expressly waived and released.

IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be duly executed all as of the day and year first above written.

EFFECTIVE UNDER THE SECURITIES ACT AND WHICH CONTINUES TO BE EFFECTIVE AT THE TIME OF SUCH TRANSFER; AND

VITESSE SEMICONDUCTOR CORPORATION, a Delaware corporation (the “Company”, which term includes any successor corporation under the Indenture hereinafter referred to), for value received, hereby promises to pay to or its registered assigns, the principal sum listed on the Schedule of Increases or Decreases in Global Security attached hereto on October 1, 2024.

Reference is hereby made to the further provisions of this Security set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

IN WITNESS WHEREOF, the Company has caused this Security to be duly executed manually or by facsimile by its duly authorized officers.

Capitalized terms used herein but not defined shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

Vitesse Semiconductor Corporation, a Delaware corporation (the “Company”), promises to pay interest on the principal amount of this Security at the Interest Rate from September 22, 2004 until repayment at Maturity, redemption or repurchase. The Company will pay interest on this Security semiannually in arrears on April 1 and October 1 of each year (each an “Interest Payment Date”), commencing April 1, 2005.

Interest on the Securities shall be computed (i) for any full semiannual period for which a particular Interest Rate is applicable on the basis of a 360-day year of twelve 30-day months and (ii) for any period for which a particular Interest Rate is applicable shorter than a full semiannual period for which interest is calculated, on the basis of a 30-day month and, for such periods of less than a month, the actual number of days elapsed over a 30-day month.

A Holder of any Security at the close of business on a Regular Record Date shall be entitled to receive interest (including Additional Amounts, if any) on such Security on the corresponding Interest Payment Date. A Holder of any Security which is converted after the close of business on a Regular Record Date and prior to the corresponding Interest Payment Date (other than any Security whose Maturity is prior to such Interest Payment Date) shall be entitled to receive interest on the principal amount of such Security, notwithstanding the conversion of such Security prior to such Interest Payment Date. However, any such Holder which surrenders any such Security for conversion during the period between the close of business on such Regular Record Date and ending with the opening of business on the corresponding Interest Payment Date shall be required to pay the Company an amount equal to the interest (including Additional Amounts, if any) on the principal amount of such Security so converted, which is payable by the Company to such Holder on such Interest Payment Date, at the time such Holder surrenders such Security for conversion. Notwithstanding the foregoing, any such Holder which surrenders for conversion any Security which has been called for redemption by the Company on a date that is after a Record Date but prior to the corresponding Interest Payment Date in a notice of redemption given by the Company pursuant to Section 10.4 of the Indenture shall be entitled to receive (and retain) such interest (including Additional Amounts, if any) and need not pay the Company an amount equal to the interest on the principal amount of such Security so converted at the time such Holder surrenders such Security for conversion.

In accordance with the terms of the Resale Registration Rights Agreement, dated September 22, 2004 (the “Registration Rights Agreement”), between the Company and Lehman Brothers Inc., during the first 90 days following a Registration Default (as defined in the Registration Rights Agreement), the Interest Rate borne by the Transfer Restricted Securities (as defined in Registration Rights Agreement) shall be increased by 0.25% on:

(A) January 20, 2005, if the Shelf Registration Statement (as defined in the Registration Rights Agreement) is not filed prior to or on January 20, 2005;

(B) March 21, 2005, if the Shelf Registration Statement is not declared effective by the Securities and Exchange Commission prior to or on March 21, 2005;

(C) the day after the tenth Business Day after the Shelf Registration Statement, previously declared effective, ceases to be effective or fails to be usable, if a post-effective amendment (or report filed pursuant to the Exchange Act) that cures the Shelf Registration Statement is not filed with the Securities and Exchange Commission during such five Business Day period; or

(D) the day following the 45^th or 60^th day, as the case may be, of any period that the prospectus contained in the Shelf Registration Statement has been suspended, if such suspension has not been terminated.

From and after the 91^st day following such Registration Default, the Interest Rate borne by the Transfer Restricted Securities shall be increased by an additional 0.25%. In no event shall the Interest Rate borne by the Transfer Restricted Securities be increased by more than 0.50%.

Any amount of additional interest will be payable in cash semiannually, in arrears, on each Interest Payment Date and will cease to accrue on the earlier of (i) the date the Registration Default is cured and (ii) the day immediately prior to the date on which this Security ceases to be a Transfer Restricted Security. The Holder of this Security is entitled to the benefits of the Registration Rights Agreement.

Interest on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest.

Principal of, and premium, if any, and interest (including Additional Amounts, if any) on, Global Securities will be payable to the Depositary in immediately available funds.

Principal and premium, if any, on Physical Securities will be payable at the office or agency of the Company maintained for such purpose, initially the Corporate Trust Office of the Trustee. Interest (including Additional Amounts, if any) on Physical Securities will be payable by (i) U.S. Dollar check mailed to the address of the Person entitled thereto as such address shall appear in the Register, or (ii) upon application to the Registrar not later than the relevant Record Date by a Holder of an aggregate principal amount in excess of $5,000,000, wire transfer in immediately available funds to an account within the United States, which application will remain in effect until the Holder notifies, in writing, the Registrar to the contrary.

Initially, U.S. Bank National Association, the Trustee under the Indenture, will act as Paying Agent and Registrar. The Company may change the Paying Agent or Registrar without notice to any Holder.

The Company issued this Security under an Indenture, dated as of September 22, 2004 (the “Indenture”), between the Company and U.S. Bank National Association, as trustee (the “Trustee”). The terms of the Security include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the “TIA”). This Security is subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of all such terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Security and the terms of the Indenture, the terms of the Indenture shall control.

On or after October 1, 2009, the Company may, at its option, redeem this Security in whole at any time or in part from time to time, on any date prior to Maturity, upon notice as set forth in Section 10.4 of the Indenture, at the Redemption Price (as defined in the Indenture) plus any interest (including Additional Amounts, if any) accrued and unpaid to, but excluding, the Redemption Date; provided, however, that the Company may redeem this Security in whole at any time or in part from time to time, on any date after October 1, 2007 and prior to October 1, 2009, upon notice as set forth in Section 10.4 of the Indenture, at the Redemption Price plus any interest (including Additional Amounts, if any) accrued and unpaid to, but excluding, the Redemption Date, if the closing sale price of the Company’s Common Stock (the “Common Stock”) has been at least 170% of the Conversion Price then in effect for at least 20 Trading Days (as defined in the Indenture) during any 30 consecutive Trading Day period.

Securities in original denominations larger than $1,000 may be redeemed in part. If any Security selected for partial redemption is converted in part before termination of the conversion right with respect to the portion of the Security so selected, the converted portion of such Security shall be deemed to be the portion selected for redemption (provided, however, that the Holder of such Security so converted and deemed redeemed shall not be entitled to any additional interest payment as a result of such deemed redemption than such Holder would have otherwise been entitled to receive upon conversion of such Security). Securities which have been converted during a selection of Securities to be redeemed may be treated by the Trustee as Outstanding for the purpose of such selection.

On and after the Redemption Date, interest ceases to accrue on Securities or portions of Securities called for redemption, unless the Company defaults in the payment of the Redemption Price.

Notice of redemption will be given by the Company to the Holders as provided in the Indenture.

6. Repurchase at the Option of a Holder upon Specific Repurchase Dates or upon a Fundamental Change.

On October 1, 2009, 2014 and 2019, (each, a “Specific Repurchase Date”) each Holder shall have the right (the “Repurchase Right”), at the Holder’s option, to require the Company to purchase for cash, and upon the exercise of such right the Company shall purchase, all of such Holder’s Securities not previously called for redemption, or any portion of the principal amount thereof that is equal to $1,000 or an integral multiple thereof as directed by such Holder pursuant to Section 11.3 of the Indenture (provided that no single Security may be repurchased in part unless the portion of the principal amount of such Security to be Outstanding after such repurchase is equal to $1,000 or an integral multiple thereof), at a purchase price equal to 100% of the principal amount of the Securities to be purchased (the “Repurchase Price”), plus accrued and unpaid interest and Additional Amounts, if any, on such Securities to, but excluding the Specific Repurchase Date. Holders may submit their Securities for repurchase to the Paying Agent at any time from the opening of business on the date that is 20 Business Days prior to the applicable Specific Repurchase Date until the close of business on the Business Day prior to the applicable Specific Repurchase Date.

In the event that a Fundamental Change (as defined in the Indenture) (together with the Specific Repurchase Dates, “Repurchase Events”) shall occur, each Holder shall have the right, at the Holder’s option, but subject to the provisions of Section 11.2 of the Indenture, to require the Company to repurchase, and upon the exercise of such right the Company shall repurchase, all of such Holder’s Securities not previously called for redemption, or any portion of the principal amount thereof that is equal to $1,000 or an integral multiple thereof as directed by such Holder pursuant to Section 11.3 of the Indenture (provided that no single Security may be repurchased in part unless the portion of the principal amount of such Security to be Outstanding after such repurchase is equal to $1,000 or an integral multiple thereof), on a date (the “Fundamental Change Repurchase Date” and, together with the Specific Repurchase Date, the “Repurchase Date”) that is not less than 20 nor more than 35 Business Days after the date of the Repurchase Event Notice (as defined in the Indenture) for an amount equal to the sum of (i) the Repurchase Price plus accrued and unpaid interest and Additional Amounts, if any, to, but excluding, the Fundamental Change Purchase Date (as defined in the Indenture) and (ii) the Make-Whole Premium (as defined in the Indenture), if any; provided, however, that installments of interest on Securities whose Stated Maturity is prior to or on the Fundamental Change Purchase Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such on the relevant Regular Record Date according to their terms and the provisions of Section 2.1 of the Indenture.

The Repurchase Price payable in the event of a Fundamental Change shall be payable at the Company’s option in the same forms of consideration that the Company may use in satisfaction of its obligation upon conversion of the Securities pursuant to Article 12 of the Indenture, including cash, shares of Common Stock or a combination of cash and shares of Common Stock. However, if the Company has irrevocably elected to make a cash payment of principal upon conversion pursuant to Section 12.12(f) of the Indenture, the Company shall repay the principal amount of the Securities repurchased in the event of a Fundamental Change in cash, with any remaining amount to be satisfied in shares of Common Stock.

No fractional shares of Common Stock will be issued upon repurchase of any Securities. Instead of any fractional share of Common Stock which would otherwise be issued upon conversion of such Securities, the Company shall pay a cash adjustment as provided in the Indenture.

Subject to and upon compliance with the provisions of the Indenture, the Holder of Securities is entitled, at such Holder’s option, at any time before the close of business on the Business Day immediately preceding October 1, 2024, to convert the Holder’s Securities (or any portion of the principal amount hereof which is an integral multiple of $1,000), at the principal amount thereof or of such portion, into duly authorized, fully paid and nonassessable shares of Common Stock at the Conversion Price in effect at the time of conversion.

In the case of a Security (or a portion thereof) called for redemption, such conversion right in respect of the Security (or such portion thereof) so called, shall expire at the close of business on the second Business Day preceding the Redemption Date, unless the Company defaults in making the payment due upon redemption. In the case of a Fundamental Change for which the Holder exercises its Repurchase Right with respect to a Security (or a portion thereof), such conversion right in respect of the Security (or portion thereof) shall expire at the close of business on the Business Day preceding the Repurchase Date.

The Conversion Price shall be initially equal to $3.92 per share of Common Stock. The Conversion Price shall be adjusted under certain circumstances as provided in the Indenture.

To exercise the conversion right, the Holder must surrender the Security (or portion thereof) duly endorsed or assigned to the Company or in blank, at the office of the Conversion Agent, accompanied by a duly signed conversion notice to the Company, with a copy to the Trustee. Any Security surrendered for conversion during the period from the close of business on any Regular Record Date to the opening of business on the corresponding Interest Payment Date (other than any Security whose Maturity is prior to such Interest Payment Date), shall also be accompanied by payment in New York Clearing House funds or other funds acceptable to the Company of an amount equal to the interest payable on such Interest Payment Date on the principal amount of the Securities being surrendered for conversion.

No fractional shares of Common Stock will be issued upon conversion of any Securities. Instead of any fractional share of Common Stock which would otherwise be issued upon conversion of such Securities, the Company shall pay a cash adjustment as provided in the Indenture.

The Indebtedness evidenced by this Security is, to the extent and in the manner provided in the Indenture, subordinated and subject in right of payment to the prior payment in full of all amounts then due on all Senior Debt of the Company, and this Security is issued subject to such provisions of the Indenture with respect thereto. Each Holder of this Security, by

accepting the same, (a) agrees to and shall be bound by such provisions, (b) authorizes and directs the Trustee on such Holder’s behalf to take such action as may be necessary or appropriate to effectuate the subordination so provided and (c) appoints the Trustee such Holder’s attorney-in-fact for any and all such purposes.

The Securities are issuable in registered form, without coupons, in denominations of $1,000 and integral multiples of $1,000 in excess thereof. A Holder may register the transfer or exchange of Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may require a Holder to pay any taxes and fees required by law or permitted by the Indenture.

In the event of a redemption in part, the Company will not be required (a) to register the transfer of, or exchange, Securities for a period of 15 Business Days immediately preceding the date notice is given identifying the serial numbers of the Securities called for such redemption, or (b) to register the transfer of, or exchange, any such Securities, or portion thereof, called for redemption.

In the event of redemption, conversion or repurchase of the Securities in part only, a new Security or Securities for the unredeemed, unconverted or unrepurchased portion thereof will be issued in the name of the Holder hereof.

The registered Holder of this Security shall be treated as its owner for all purposes.

The Trustee and the Paying Agent shall pay to the Company any money held by them for the payment of principal, premium, if any, or interest that remains unclaimed for two years after the date upon which such payment shall have become due. After payment to the Company, Holders entitled to the money must look to the Company for payment as general creditors unless an applicable abandoned property law designates another Person, and all liability of the Trustee and such Paying Agent with respect to such money shall cease.

Subject to certain conditions contained in the Indenture, the Company may discharge its obligations under the Securities and the Indenture if (1) (a) all of the Outstanding Securities shall become due and payable at their scheduled Maturity within one year or (b) all of the Outstanding Securities are scheduled for redemption within one year, and (2) the Company shall have deposited with the Trustee money and/or U.S. Government Obligations sufficient to pay the principal of, and premium, if any, and interest on, all of the Outstanding Securities on the date of Maturity or redemption, as the case may be.

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 a majority in aggregate principal amount of the Outstanding Securities (or such lesser amount as shall have acted at a meeting pursuant to the provisions of the Indenture). The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, 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 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 or such other Security.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and premium, if any, and interest (including Additional Amounts, if any) on this Security at the times, places and rate, and in the coin or currency, herein prescribed or to convert this Security (or pay cash in lieu of conversion) as provided in the Indenture.

The Indenture provides that an Event of Default with respect to the Securities occurs when any of the following occurs:

(a) the Company defaults in the payment of the principal of or premium, if any, on any of the Securities when it becomes due and payable at Maturity, upon redemption or exercise of a Repurchase Right or otherwise, whether or not such payment is prohibited by the subordination provisions of Article 14 of the Indenture;

(b) the Company defaults in the payment of interest (including Additional Amounts, if any) on any of the Securities when it becomes due and payable and such default continues for a period of 30 days, whether or not such payment is prohibited by the subordination provisions of Article 14 of the Indenture;

(c) the Company fails to perform or observe any other term, covenant or agreement contained in the Securities or the Indenture and such default continues for a period of 60 days after written notice of such failure is given as specified in the Indenture;

(d) the Company (i) defaults in the performance of any covenant or agreement contained in any agreements, indentures or instruments under which the Company has incurred Indebtedness of $15,000,000 or more in the aggregate (not including any amounts the Company may owe under reimbursement or similar obligations to banks,

sureties or other entities which have issued letters of credit, surety bonds, performance bonds or other guarantees relating to the performance by the Company or its Subsidiaries of contractual obligations to customers, to the extent any demands made under any such reimbursement or similar obligation relate to a draw under the related letter of credit or other instrument which draw is being contested in good faith through appropriate proceedings) whether such indebtedness now exists or shall hereafter be created, and (ii) such default has caused the holders of such Indebtedness to declare such Indebtedness to be due and payable prior to its stated maturity and such Indebtedness has not been discharged in full or such acceleration has not been rescinded or annulled by the 30^th day after written notice of such failure is given as specified in the Indenture; or

(e) there are certain events of bankruptcy, insolvency or reorganization of the Company.

If an Event of Default shall occur and be continuing, the principal of all the Securities may be declared due and payable in the manner and with the effect provided in the Indenture.

This Security shall not be valid until the Trustee (or authenticating agent) executes the certificate of authentication on the other side of this Security.

Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian) and U/G/M/A (= Uniform Gifts to Minors Act).

In addition to the rights provided to Holders under the Indenture, Holders of Transfer Restricted Securities shall have all the rights set forth in the Registration Rights Agreement.

Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on this Security and the Trustee may use CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on this Security or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon.

The Indenture and this Security shall be governed by, and construed in accordance with, the law of the State of New York.

In the event a successor corporation assumes all the obligations of the Company under this Security, pursuant to the terms hereof and of the Indenture, the Company will be released from all such obligations.

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