 (b) Restricted Global Securities. All of the Securities
are initially being offered and sold in reliance on Rule 144A (“Rule 144A”) or in reliance on Regulation S (“Regulation S”) under the Securities Act and shall be issued initially in the form of one or more Restricted Global
Securities, which shall be deposited on behalf of the purchasers of the Securities represented thereby with the Trustee, at its Corporate Trust Office, as custodian for the depositary, The Depository Trust Company (“DTC”) (such depositary,

principal amount of the Restricted Global Security may from time to time be increased or decreased by adjustments made on the records of the Securities Custodian as hereinafter provided, subject in each case to compliance with the Applicable
Procedures. 
  
 (c) Global Securities in General. Each
Global Security shall represent such of the outstanding Securities as shall be specified therein and each shall provide that it shall represent the aggregate amount of outstanding Securities from time to time endorsed thereon and that the aggregate

increase or decrease in the amount of outstanding Securities represented thereby shall be made by the Securities Custodian in accordance with the standing instructions and procedures existing between the Depositary and the Securities Custodian.

governing the exercise of the rights of a Holder of any Security.

nevertheless. 






Table of Contents

 A Security shall not be valid until an authorized signatory of the Trustee manually signs the certificate
of authentication on the Security. The signature shall be conclusive evidence that the Security has been authenticated under this Indenture. 
  
 On the Issue Date, the Trustee shall authenticate and deliver up to $150.0 million of 2.50% Convertible Subordinated Notes Due June 1, 2008, which will be

portion of such remainder within 30 days following the Issue Date as may be necessary in connection with any exercise by Lehman Brothers Inc. of its over-allotment option pursuant to the Purchase Agreement dated May 22, 2003, between the Company and

 The Trustee may appoint an authenticating
agent reasonably acceptable to the Company to authenticate 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

SECTION 2.03. Registrar, Paying Agent and Conversion Agent. The Company shall maintain an office or agency where Securities may be presented for registration of transfer or for exchange (the “Registrar”),
an office or agency where Securities may be presented for payment (the “Paying Agent”) and one or more offices or agencies where securities may be presented for conversion (each, a “Conversion Agent”). The Registrar shall keep a
register of the Securities and of their transfer and exchange. The Company may have one or more co-registrars and one or more additional paying agents. The term “Paying Agent” includes any additional paying agent. 
  
 The Company shall enter into an appropriate agency agreement with any
Registrar, co-registrar, Paying Agent or Conversion Agent not a party to this Indenture, which shall incorporate the terms of the TIA. The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify
the Trustee of the name and address of any such agent. If the Company fails to maintain a Registrar, Paying Agent or Conversion Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 8.07.
The Company may act as Paying Agent, Registrar, co-registrar, transfer agent or Conversion Agent. 
  
 The Company initially appoints the Trustee as Registrar, Paying Agent and Conversion Agent in connection with the Securities. 
  
 
SECTION 2.04. Maintenance of Office or Agency. The Company shall maintain in the Borough of Manhattan, the City of New York, an office or agency (which may be an office of the Trustee or an affiliate of the
Trustee, Registrar or co-registrar) where Securities may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Company in respect of the Securities and this

Indenture may be served. Such office shall initially be the office of U.S. Bank National Association. The Company shall give prompt written notice to the
Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such
presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee. 
  
 The Company may also from time to time designate one or more other offices or agencies where the Securities may be presented or surrendered for any or all
such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of
Manhattan, the City of New York for such purposes. The Company shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. 
  
 
SECTION 2.05. Paying Agent To Hold Money in Trust. Prior to each due date of the principal and interest on any Security, the Company shall deposit with the Paying Agent a sum sufficient to pay such principal and
interest when so becoming due. The Company shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Securityholders or the Trustee all money held by the Paying Agent
for the payment of principal of or interest on the Securities and if the Paying Agent is different than the Trustee, shall notify the Trustee of any default by the Company in making any such payment, and while any such default continues, the Trustee
may require the Paying Agent to pay all money held by it to the Trustee. If the Company or a Subsidiary acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may
require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed by the Paying Agent. Upon complying with this Section, the Paying Agent shall have no further liability for the money delivered to the Trustee.

  
 
SECTION 2.06. Securityholder Lists. 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 Securityholders. If the Trustee
is not the Registrar, the Company shall furnish to the Trustee, in writing at least five Business Days before 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 Securityholders. 
  
 
SECTION 2.07. Transfer and Exchange. The Securities shall be issued in registered form and shall be transferable only upon the surrender of a Security for registration of transfer. When a Security is presented to
the Registrar or a co-registrar with a request to register a transfer, the Registrar shall register the transfer as requested if the requirements of this Indenture are satisfied. When Securities are presented to the Registrar or a co-registrar with
a request to exchange them for an equal principal amount of Securities of other denominations, the Registrar shall make the exchange as requested if the same requirements are met. To permit registration of transfers and exchanges, the

 14 
  

 
Company shall execute and the Trustee shall authenticate Securities at the Registrar’s or co-registrar’s request. The Company or the Registrar may
require payment by the Holder of a sum sufficient to pay all taxes, assessments or other governmental charges in connection with any transfer or exchange pursuant to this Section. The Company shall not be required to make and the Registrar need not
register transfers or exchanges of any Securities for 15 days before an interest payment date. 
  
 Prior to the due presentation for registration of transfer of any Security, the Company, the Trustee, the Paying Agent, the Registrar or any co-registrar may deem and treat the person in whose name a Security is
registered as the absolute owner of such Security for the purpose of receiving payment of principal of and (subject to the provisions of the Securities with respect to record dates) interest on such Security and for all other purposes whatsoever,
whether or not such Security is overdue, and none of the Company, the Trustee, the Paying Agent, the Registrar or any co-registrar shall be affected by notice to the contrary. 
  
 All Securities issued upon any transfer or exchange pursuant to the terms of this Indenture will evidence the same debt and
will be entitled to the same benefits under this Indenture as the Securities surrendered upon such transfer or exchange. 
  
 
SECTION 2.08. Additional Transfer and Exchange Requirements. 
  
 (a) Transfer and Exchange of Global Securities. 
  
 (1) Certificated Securities shall be issued in exchange for interests in the Global Securities only if (x) the Depositary notifies the

principal amount equal to the principal amount of such Global Securities in exchange therefor. Only Restricted Certificated Securities shall be issued in exchange for beneficial interests in Restricted Global Securities, and only Unrestricted
Certificated Securities shall be issued in exchange for beneficial interests in Unrestricted Global Securities. Certificated Securities issued in exchange for beneficial interests in Global Securities shall be registered in such names and shall be
in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. The Trustee shall deliver or cause to be delivered such Certificated Securities to the
persons in whose names such Securities are so registered. Such exchange shall be effected in accordance with the Applicable Procedures.

Global Securities in accordance with Section 2.08(a)(1) of this Indenture, on or after such event when Certificated Securities are presented by a Holder to a Registrar with a request: 
  
 (x) to register the transfer of the Certificated Securities to a person who will take delivery thereof in
the form of Certificated Securities only; or 
  
 (y) to exchange such Certificated Securities for an equal principal amount of Certificated Securities of other authorized denominations, such Registrar shall register the transfer or make the exchange as requested if the requirements for
such transaction under this Indenture are satisfied; 
  
 provided, however, that
the Certificated Securities presented or surrendered for register of transfer or exchange: 
  
 (1) shall be duly endorsed or accompanied by an assignment form and, if applicable, a transfer certificate each in the form included in
Exhibit A, and in a form satisfactory to the Registrar duly executed by the Holder thereof or its attorney duly authorized in writing; and

documents, as applicable:

Restricted Certificated Security is being delivered to the Registrar by a Holder for registration in the name of such Holder, without transfer, or such Restricted Certificated Security is being transferred to the Company or a Subsidiary of the
Company, a certification to that effect from such Holder (in substantially the form set forth in the Transfer Certificate);

buyer as defined in Rule 144A (“QIB”) in accordance with Rule 144A or pursuant to an effective registration statement under the Securities Act, a certification to that effect from such Holder (in substantially the form set forth in the
Transfer Certificate); or

Table of Contents



 16 
  

 
shall cease to be a “restricted security” within the meaning of Rule 144, a certification to that effect from the Holder (in substantially the form
set forth in the Transfer Certificate) and, if the Company or such Registrar so requests, an Opinion of Counsel, certificates and other information reasonably acceptable to the Company and such Registrar to the effect that such transfer is in
compliance with the registration requirements of the Securities Act. 
  
 (c) Transfer of a Beneficial Interest in a Restricted Global Security for a Beneficial Interest in an Unrestricted Global Security. Any person having a beneficial interest in a Restricted Global Security may upon request, subject to
the Applicable Procedures, transfer such beneficial interest to a person who is required or permitted to take delivery thereof in the form of an Unrestricted Global Security. Upon receipt by the Trustee of written instructions, or such other form of
instructions as is customary for the Depositary, from the Depositary or its nominee on behalf of any person having a beneficial interest in a Restricted Global Security and the following additional information and documents in such form as is
customary for the Depositary from the Depositary or its nominee on behalf of the person having such beneficial interest in the Restricted Global Security (all of which may be submitted by facsimile or electronically): 
  
 (1) if such beneficial interest is being transferred pursuant
to an effective registration statement under the Securities Act, a certification to that effect from the transferor (in substantially the form set forth in the Transfer Certificate); or 
  
 (2) if such beneficial interest is being transferred (i) pursuant to an exemption from the registration
requirements of the Securities Act in accordance with Rule 144, (ii) outside the United States in an offshore transaction within the meaning of Regulation S under the Securities Act in compliance with Rule 904 under the Securities Act or (iii) (A)
pursuant to an exemption from the registration requirements of the Securities Act (other than pursuant to Rule 144A, Rule 144 or Rule 904) and (B) as a result, such Security shall cease to be a “restricted security” within the meaning of
Rule 144, a certification to that effect from the transferor (in substantially the form set forth in the Transfer Certificate) and, if the Company or the Trustee so requests, an Opinion of Counsel, certificates and other information reasonably
acceptable to the Company and the Trustee to the effect that such transfer is in compliance with the registration requirements of the Securities Act, the Trustee, as a Registrar and Securities Custodian, shall reduce or cause to be reduced the
aggregate principal amount of the Restricted Global Security by the appropriate principal amount and shall increase or cause to be increased the aggregate principal amount of the Unrestricted Global Security by a like principal amount. Such transfer
shall otherwise be effected in accordance with the Applicable Procedures. If no Unrestricted Global Security is then outstanding, the Company shall execute and the Trustee shall, upon receipt of a Company Order (which the Company agrees to deliver
promptly), authenticate and deliver an Unrestricted Global Security. 
  
 (d) Transfer of a Beneficial Interest in an Unrestricted Global Security for a Beneficial Interest in a Restricted Global Security. Any person having a beneficial

interest in an Unrestricted Global Security may upon request, subject to the Applicable Procedures, transfer such beneficial interest to a person who is
required or permitted to take delivery thereof in the form of a Restricted Global Security (it being understood that only QIBs may own beneficial interests in Restricted Global Securities). Upon receipt by the Trustee of written instructions or such
other form of instructions as is customary for the Depositary, from the Depositary or its nominee, on behalf of any person having a beneficial interest in an Unrestricted Global Security and, in such form as is customary for the Depositary, from the
Depositary or its nominee on behalf of the person having such beneficial interest in the Unrestricted Global Security (all of which may be submitted by facsimile or electronically) a certification from the transferor (in substantially the form set
forth in the Transfer Certificate) to the effect that such beneficial interest is being transferred to a person that the transferor reasonably believes is a QIB in accordance with Rule 144A. The Trustee, as a Registrar and Securities Custodian,
shall reduce or cause to be reduced the aggregate principal amount of the Unrestricted Global Security by the appropriate principal amount and shall increase or cause to be increased the aggregate principal amount of the Restricted Global Security
by a like principal amount. Such transfer shall otherwise be effected in accordance with the Applicable Procedures. If no Restricted Global Security is then outstanding, the Company shall execute and the Trustee shall, upon receipt of a Company
Order (which the Company agrees to deliver promptly), authenticate and deliver a Restricted Global Security. 
  
 (e) Transfers of Certificated Securities for Beneficial Interest in Global Securities. In the event that Certificated Securities are issued in
exchange for beneficial interests in Global Securities and, thereafter, the events or conditions specified in Section 2.08(a)(1) which required such exchange shall cease to exist, the Company shall mail notice to the Trustee and to the Holders
stating that Holders may exchange Certificated Securities for interests in Global Securities by complying with the procedures set forth in this Indenture and briefly describing such procedures and the events or circumstances requiring that such
notice be given. Thereafter, if Certificated Securities are presented by a Holder to a Registrar with a request: 
  
 (x) to register the transfer of such Certificated Securities to a person who will take delivery thereof in the form of a beneficial
interest in a Global Security, which request shall specify whether such Global Security will be a Restricted Global Security or an Unrestricted Global Security; or 
  
 (y) to exchange such Certificated Securities for an equal principal amount of beneficial interests in a
Global Security, which beneficial interests will be owned by the Holder transferring such Certificated Securities (provided that in the case of such an exchange, Restricted Certificated Securities may be exchanged only for Restricted Global
Securities and Unrestricted Certificated Securities may be exchanged only for Unrestricted Global Securities), the Registrar shall register the transfer or make the exchange as requested by canceling such Certificated Security and causing, or
directing the Securities Custodian to cause, the aggregate principal amount of the applicable Global Security to be increased accordingly

from the registration requirements of the Securities Act (other than pursuant to Rule 144A, Rule 144 or Rule 904) and (B) as a result, such Security shall cease to be a “restricted security” within the meaning of Rule 144, a certification
to that effect from such Holder (in substantially the form set forth in the Transfer Certificate), and, if the Company or the Registrar so requests, an Opinion of Counsel, certificates and other information reasonably acceptable to the Company and
the Trustee to the effect that such transfer is in compliance with the registration requirements of the Securities Act; 
  
 (3) in the case of a Restricted Certificated Security to be transferred or exchanged for a beneficial interest in a Restricted Global
Security, such request shall be accompanied by a certification from such Holder (in substantially the form set forth in the Transfer Certificate) to the effect that such Restricted Certificated Security is being transferred to a person the Holder

 (1) Except as permitted by the following paragraphs (2) and (3), each Global
Security and Certificated Security (and all Securities issued in exchange therefor or upon registration of transfer or replacement thereof) shall bear a legend in substantially the form called for by footnote 2 to Exhibit A hereto (each a
“Transfer Restricted Security” for so long as it is required by this Indenture to bear such legend). Each Transfer Restricted Security shall have attached thereto a certificate (a “Transfer Certificate”) in substantially the form
called for by footnote 5 to Exhibit A hereto. 
  
 (2) Upon
any sale or transfer of a Transfer Restricted Security (v) after the expiration of the holding period applicable to sales of the Securities under Rule 144(k) of the Securities Act, (w) pursuant to Rule 144, (x) outside the United States in an
offshore transaction within the meaning of Regulation S under the Securities Act in compliance with Rule 904 under the Securities Act (y) pursuant to an effective registration statement under the Securities Act or (z)(A) pursuant to any other
available exemption (other than Rule 144A, Rule 144 or Rule 904) from the registration requirements of the Securities Act and (B) as a result, such Security shall cease to be a “restricted security” within the meaning of Rule 144:

Security to a transferee who shall take such Security in the form of a beneficial interest in an Unrestricted Global Security, and in each case shall rescind any restriction on the transfer of such Security; provided, however, that the
Holder of such Restricted Certificated Security shall, in connection with such exchange or transfer, comply with the other applicable provisions of this Section 2.08; and 
  
 (ii) in the case of any beneficial interest in a Restricted Global Security, the Trustee shall permit the
beneficial owner thereof to transfer such beneficial interest to a transferee who shall take such interest in the form of a beneficial interest in an Unrestricted Global Security and shall rescind any restriction on transfer of such beneficial
interest; provided, however, that such Unrestricted Global Security shall continue to be subject to the provisions of Section 2.08(a)(2); and provided further, that the owner of such beneficial interest shall, in
connection with such transfer, comply with the other applicable provisions of this Section 2.07.

 (4) After the expiration of the holding period pursuant to Rule 144(k) of the Securities Act, the Company
may with the consent of the Holder of a Restricted Global Security or Restricted Certificated Security, remove any restriction of transfer on such Security, and the Company shall execute, and the Trustee shall authenticate and deliver Securities
that do not bear such legend and that do not have a Transfer Certificate attached thereto. 
  
 (g) Transfers to the Company. Nothing in this Indenture or in the Securities shall prohibit the sale or other transfer of any Securities (including beneficial interests in Global Securities) to the Company or
any of its Subsidiaries. 
  
 (h) No Obligation of the
Trustee. 
  
 (i) The Trustee shall have no
responsibility or obligation to any beneficial owner of a Global Security, a member of, or a participant in the Depository or other Person with respect to the accuracy of the books or records, or the acts or omissions, of the Depository or its
nominee or of any participant or member thereof, with respect to any ownership interest in the Securities or with respect to the delivery to any participant, member, beneficial owner or other Person (other than the Depository) of any notice or the
payment of any amount, under or with respect to such Securities. All notices and communications to be given to the Holders and all payments to be made to Holders under the Securities shall be given or made only to or upon the order of the registered
Holders (which shall be the Depository or its nominee in the case of a Global Security). The rights of beneficial owners in any Global Security shall be exercised only through the Depository subject to the Applicable Procedures of the Depository.
The Trustee may rely and shall be fully protected in relying upon information furnished by the Depository with respect to its members, participants and any beneficial owners. 
  
 (ii) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any
restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Security (including any transfers between or among Depository participants, members or beneficial owners in any Global
Security) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Indenture, and to examine the same to determine
substantial compliance as to form with the express requirements hereof. 
  
 
SECTION 2.09. CUSIP Numbers. The Company in issuing the Securities may use “CUSIP” numbers (if then generally in use) and, if so, the Trustee shall use “CUSIP” numbers in notices of purchase as
a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any 







Table of Contents



 21 
  

 
notice of a purchase and that reliance may be placed only on the other identification numbers printed on the Securities, and any such purchase shall not be
affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee of any change in the “CUSIP” numbers. 
  
 
SECTION 2.10. Replacement Securities. If a mutilated Security is surrendered to the Registrar or if the Holder of a Security claims that the Security has been lost, destroyed or wrongfully taken, the Company shall
issue and the Trustee shall authenticate a replacement Security if the requirements of this Indenture are met and the Holder satisfies any other reasonable requirements of the Trustee. If required by the Trustee or the Company, such Holder shall
furnish an indemnity bond sufficient in the judgment of the Company and the Trustee to protect the Company, the Trustee, the Paying Agent, the Registrar and any co-registrar from any loss which any of them may suffer if a Security is replaced. The
Company and the Trustee may charge the Holder for their expenses in replacing a Security. 
  
 Upon the issuance of any new Securities under this Section 2.10, the Company or the Registrar may require the payment by a Holder of a sum sufficient to cover any tax or other governmental charge that may be imposed
in relation thereto. 
  
 Every replacement Security is an
additional Obligation of the Company. 
  
 
SECTION 2.11. Outstanding Securities. Securities outstanding at any time are all Securities authenticated by the Trustee except for those cancelled by it, those delivered to it for cancellation and those described
in this Section as not outstanding. A Security does not cease to be outstanding because the Company or an Affiliate of the Company holds the Security. 
  
 If a Security is replaced pursuant to Section 2.10, it ceases to be outstanding unless the Trustee and the Company receive proof satisfactory to them that
the replaced Security is held by a bona fide purchaser, in which case the replacement Security shall cease to be outstanding, subject to the provisions of this Indenture. 
  
 If the Paying Agent segregates and holds in trust, in accordance with this Indenture, on a maturity date money sufficient to
pay all principal and interest payable on that date with respect to the Securities maturing and the Paying Agent is not prohibited from paying such money to the Securityholders on that date pursuant to the terms of this Indenture, then on and after
that date such Securities (or portions thereof) cease to be outstanding and interest on them ceases to accrue. 
  
 
SECTION 2.12. Temporary Securities. Until definitive Securities are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Securities. Temporary Securities shall be substantially
in the form of definitive Securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Securities and deliver
them in exchange for temporary Securities.

SECTION 2.13. Cancellation. The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar, the Paying Agent and the Conversion Agent shall forward to the Trustee any Securities
surrendered to them for registration of transfer, exchange, payment, replacement, conversion or cancellation. The Trustee and no one else shall cancel and destroy all Securities surrendered for registration of transfer, exchange, payment,
replacement, conversion or cancellation and deliver a certificate of such destruction to the Company unless the Company directs the Trustee to deliver cancelled Securities to the Company. The Company may not issue new Securities to replace
Securities it has paid or that have been delivered to the Trustee for cancellation. 
  
 
SECTION 2.14. Defaulted Interest. If the Company defaults in a payment of interest on the Securities, the Company shall pay defaulted interest (plus interest on such defaulted interest to the extent lawful) in any
lawful manner. The Company may pay the defaulted interest to the persons who are Securityholders on a subsequent special record date. The Company shall fix or cause to be fixed any such special record date and payment date to the reasonable
satisfaction of the Trustee and shall promptly mail to each Securityholder a notice that states the special record date, the payment date and the amount of defaulted interest to be paid.

 Covenants 
  
 
SECTION 4.01. Payment of Securities. The Company shall promptly pay the principal of and interest on the Securities on the dates and in the manner provided in the Securities and in this Indenture. Principal and
interest shall be considered paid on the date due if on such date the Trustee or the Paying Agent holds in accordance with this Indenture money sufficient to pay all principal and interest then due and the Trustee or the Paying Agent, as the case
may be, is not prohibited from paying such money to the Securityholders on that date pursuant to the terms of this Indenture. 
  
 The Company shall pay interest on overdue principal at 1% per annum in excess of the rate specified in the Securities, and it shall pay interest on
overdue installments of interest at such higher rate to the extent lawful. The conversion of any Securities pursuant to Article 5 hereof, together with the making of any cash payments required to be made in accordance with the terms of the
Securities and this Indenture, shall satisfy the Company’s obligations under this Section 4.01 with respect to such Securities. 
  
 
SECTION 4.02. SEC Reports. Whether or not subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, the Company will file with the

SEC and provide the Trustee with such annual reports and such information, documents and other reports as are specified in Sections 13 and 15(d) of the
Exchange Act and applicable to a U.S. corporation subject to such Sections, at the times specified for such filings under such Sections. The Company also shall comply with the other provisions of TIA § 314(a) as may be required under the
provisions of the TIA. Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely on an Officer’s Certificate). 
  
 
SECTION 4.03. Compliance Certificates. The Company shall deliver to the Trustee within 120 days after the end of each fiscal year of the Company certificates of the principal executive officer, the principal
financial officer or the principal accounting officer of the Company stating whether or not the signer knows of any Default that occurred during such Period. If such signer does, the certificate shall describe the Default, its status and what action
the Company is taking or proposes to take with respect thereto. The Company also shall comply with TIA § 314(a)(4). 
  
 
SECTION 4.04. Further Instruments and Acts. Upon request of the Trustee, the Company will execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out
more effectively the purpose of this Indenture. 
  
 
SECTION 4.05. Maintenance of Corporate Existence. Except as otherwise permitted in this Indenture, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its
corporate existence. 
  
 
SECTION 4.06. Payment of Additional Interest. If Additional Interest is 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 Interest that is payable and (ii) the date on which such Additional Interest is payable. Unless and until a Trust Officer of the Trustee receives such a certificate, the Trustee may assume without inquiry
that no such Additional Interest is payable. If the Company has paid Additional Interest directly to the Persons entitled to it, the Company shall deliver to the Trustee a certificate setting forth the particulars of such payment. 
  
 
SECTION 4.07. Purchase of Securities at Option of the Holder upon Change of Control. (a) If at any time that Securities remain outstanding there shall occur a Change of Control, Securities shall be purchased by
the Company at the option of the Holders thereof as of the date that is no less than 30 and no more than 60 days from the date such notice is mailed or delivered as required by paragraph (b) of this Section 4.07, (the “Change of Control
Purchase Date”) at a purchase price equal to the principal amount of the Securities, plus accrued and unpaid interest to, but excluding, the Change of Control Purchase Date (the “Change of Control Purchase Price”), subject to
satisfaction by or on behalf of any Holder of the requirements set forth in subsection (c) of this Section 4.07.

indirectly, at least a majority of the voting power of the Voting Stock of the surviving Person; or 
  
 (3) the adoption of a plan relating to the liquidation or dissolution of the Company. 
  
 Notwithstanding anything to the contrary set forth in this Section 4.07, a Change of Control
will not be deemed to have occurred if either: 
  
 (1) the Closing Price of the Company’s Common Stock for any five Trading Days during the ten Trading Days immediately preceding the Change of Control is at least equal to 105% of the Conversion Price in effect immediately preceding the
Change of Control; or 
  
 (2) 100% of the
consideration (excluding cash payments for fractional shares) received or to be received by the holders of shares of the Company’s Common Stock in the transaction or transactions constituting a Change of Control consists of shares of common

Control Purchase Notice”) to any Paying Agent at any time prior to the close of business on the Business Day next preceding the Change of Control
Purchase Date. 
  
 The delivery of such Security to any Paying
Agent (together with all necessary endorsements) at the office of such Paying Agent shall be a condition to the receipt by the Holder of the Change of Control Purchase Price therefor. Securities so surrendered for purchase (in whole or in part) in
respect of a Change of Control Purchase Date occurring 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 shall also be accompanied by payment in funds
acceptable to the Company in an amount equal to the interest payable on such interest payment date on the principal amount of such Security then being surrendered for purchase. 
  
 The Company shall purchase from the Holder thereof, pursuant to this Section 4.07, a portion of a Security if the principal
amount of such portion is $1,000 or an integral multiple of $1,000. Provisions of the Indenture that apply to the purchase of all of a Security pursuant to Sections 4.07 through 4.12 also apply to the purchase of such portion of such Security.

  
 Notwithstanding anything herein to the contrary, any Holder
delivering to a Paying Agent the Change of Control Purchase Notice contemplated by this subsection (c) shall have the right to withdraw such Change of Control Purchase Notice in whole or in a portion thereof that is a principal amount of $1,000 or
in an integral multiple thereof at any time prior to the close of business on the Business Day next preceding the Change of Control Purchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 4.08.

  
 A Paying Agent shall promptly notify the Company of the
receipt by it of any Change of Control Purchase Notice or written withdrawal thereof. 
  
 Anything herein to the contrary notwithstanding, in the case of Global Securities, any Change of Control Purchase Notice may be delivered or withdrawn and such Securities may be surrendered or delivered for purchase
in accordance with the Applicable Procedures as in effect from time to time. 
  
 
SECTION 4.08. Effect of Change of Control Purchase Notice. Upon receipt by any Paying Agent of the Change of Control Purchase Notice specified in Section 4.07(c), the Holder of the Security in respect of which
such Change of Control Purchase Notice was given shall (unless such Change of Control Purchase Notice is withdrawn as specified below) thereafter be entitled to receive the Change of Control Purchase Price with respect to such Security. Such Change
of Control Purchase Price shall be paid to such Holder promptly following the later of (a) the Change of Control Purchase Date with respect to such Security (provided the conditions in Section 4.07(c) have been satisfied) and (b) the time of
delivery of such Security to a Paying Agent by the Holder thereof in the manner required by Section 4.07(c). Securities in respect of which a Change of Control Purchase Notice has been given by the Holder thereof may not be converted into shares of
Common Stock on or after the date of the delivery of such

Change of Control Purchase Notice unless such Change of Control Purchase Notice has first been validly withdrawn. 
  
 A Change of Control Purchase Notice may be withdrawn by means of a written
notice (which may be delivered by letter, overnight courier, hand delivery, facsimile transmission or in any other written form and, in the case of Global Securities, may be delivered electronically or by other means in accordance with the
Depositary’s customary procedures) of withdrawal delivered by the Holder to a Paying Agent at any time prior to the close of business on the Business Day immediately preceding the Change of Control Purchase Date, specifying the principal amount
of the Security or portion thereof (which must be a principal amount of $1,000 or an integral multiple of $1,000 in excess thereof) with respect to which such notice of withdrawal is being submitted. 
  
 
SECTION 4.09. Deposit of Change of Control Purchase Price. On or before 11:00 a.m. New York City time on the Change of Control Purchase Date, the Company shall deposit with the Trustee or with a Paying Agent
(other than the Company or an Affiliate of the Company) an amount of money (in immediately available funds if deposited on such Business Day) sufficient to pay the aggregate Change of Control Purchase Price of all the Securities or portions thereof
that are to be purchased as of such Change of Control Purchase Date. The manner in which the deposit required by this Section 4.09 is made by the Company shall be at the option of the Company, provided that such deposit shall be made in a manner
such that the Trustee or a Paying Agent shall have immediately available funds on the Change of Control Purchase Date. 
  
 If a Paying Agent holds, in accordance with the terms hereof, money sufficient to pay the Change of Control Purchase Price of any Security for which a
Change of Control Purchase Notice has been tendered and not withdrawn in accordance with this Indenture then, on the Change of Control Purchase Date, such Security will cease to be outstanding and the rights of the Holder in respect thereof shall
terminate (other than the right to receive the Change of Control Purchase Price as aforesaid). The Company shall publicly announce the principal amount of Securities purchased as a result of such Change of Control on or as soon as practicable after
the Change of Control Purchase Date. 
  
 
SECTION 4.10. Securities Purchased in Part. Any Security that is to be purchased only in part shall be surrendered at the office of a Paying Agent and promptly after the Change of Control Purchase Date 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 such authorized denomination or denominations as may be requested by such Holder, in aggregate
principal amount equal to, and in exchange for, the portion of the principal amount of the Security so surrendered that is not purchased. 
  
 
SECTION 4.11. Compliance with Securities Laws upon Purchase of Securities. In connection with any offer to purchase or purchase of Securities under Section 4.07, the Company shall (a) comply with Rule 13e-4 and

Table of Contents



 28 
  

 
Schedule TO (or any successor or similar schedule, form or report) if required under the Exchange Act, and (c) otherwise comply with all federal and state
securities laws in connection with such offer to purchase or purchase of Securities, all so as to permit the rights of the Holders and obligations of the Company under Sections 4.07 through 4.10 to be exercised in the time and in the manner
specified therein. To the extent that the provisions of any securities laws or regulations conflict with this Article 4, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its
obligations hereunder by virtue of such compliance with such securities laws or regulations. 
  
 
SECTION 4.12. Repayment to the Company. To the extent that the aggregate amount of cash deposited by the Company pursuant to Section 4.09 exceeds the aggregate Change of Control Purchase Price together with
interest, if any, thereon of the Securities or portions thereof that the Company is obligated to purchase, then promptly after the Change of Control Purchase Date the Trustee or a Paying Agent, as the case may be, shall return any such excess cash
(including any interest thereon) to the Company. 
  
 
SECTION 4.13. Offer to Purchase by Third Party. The Company shall not be required to purchase or offer to purchase Securities upon a Change of Control pursuant to this Article 4 in the event that a Person other
than the Company makes such offer to purchase in the manner, at the times and otherwise in compliance with the requirements set forth in this Article 4 for such offer to purchase, and such Person purchases all Securities validly tendered and not
withdrawn pursuant to such offer to purchase. 
  
 ARTICLE 5

  
 Conversion 
  
 
SECTION 5.01. Conversion Privilege. Subject to the further provisions of this Article 5, a Holder of a Security may, at the Holder’s option, convert the principal amount of such Security (or any portion
thereof equal to $1,000 or any integral multiple of $1,000 in excess thereof) into Common Stock at any time prior to the close of business on the Business Day immediately preceding June 1, 2008, at the Conversion Price then in effect;
provided, however, that if such Security is submitted or presented for purchase pursuant to Article 4, such conversion right shall terminate at the close of business on the Business Day immediately preceding the Change of Control
Purchase Date for such Security or such earlier date as the Holder presents such Security for purchase (unless the Company shall default in making the Change of Control Purchase Price payment when due, in which case the conversion right shall
terminate at the close of business on the date such default is cured and such Security is purchased). The number of shares of Common Stock issuable upon conversion of a Security shall be determined by dividing the principal amount of the Security or
portion thereof surrendered for conversion by the Conversion Price in effect on the Conversion Date. The initial Conversion Price is set forth in paragraph 6 of the Securities and is subject to adjustment as provided in this Article 5.

 Provisions of this Indenture that apply to conversion of all of a Security also apply to conversion of a
portion of a Security. 
  
 A Security in respect of which a Holder
has delivered a Change of Control Purchase Notice pursuant to Section 4.07(c) exercising the option of such Holder to require the Company to purchase such Security may be converted only if such Change of Control Purchase Notice is withdrawn by a
written notice of withdrawal delivered to a Paying Agent prior to the close of business on the Business Day immediately preceding the Change of Control Purchase Date in accordance with Section 4.08. 
  
 A Holder of Securities is not entitled to any rights of a holder of Common
Stock until such Holder has converted its Securities into Common Stock, and only to the extent such Securities are deemed to have been converted into Common Stock pursuant to this Article 5. 
  
 
SECTION 5.02. Conversion Procedure. To convert a Security, a Holder must (a) complete and manually sign the conversion notice on the back of the Security and deliver such notice to a Conversion Agent, (b)
surrender the Security to a Conversion Agent, (c) furnish appropriate endorsements and transfer documents if required by a Registrar or a Conversion Agent, and (d) pay any transfer or similar tax, if required. The date on which the Holder satisfies
all of those requirements is the “Conversion Date”. As soon as practicable after the Conversion Date, the Company shall deliver to the Holder through a Conversion Agent a certificate for the number of whole shares of Common Stock issuable
upon the conversion and cash in lieu of any fractional shares pursuant to Section 5.03. Anything herein to the contrary notwithstanding, in the case of Global Securities, conversion notices may be delivered and such Securities may be surrendered for
conversion in accordance with the Applicable Procedures as in effect from time to time. 
  
 The person in whose name the Common Stock certificate is registered shall be deemed to be a stockholder of record on the Conversion Date; provided, however, that no surrender of a Security on any date
when the stock transfer books of Company shall be closed shall be effective to constitute the person or persons entitled to receive the shares of Common Stock upon such conversion as the record holder or holders of such shares of Common Stock on
such date, but such surrender shall be effective to constitute the person or persons entitled to receive such shares of Common Stock as the record holder or holders thereof for all purposes at the close of business on the next succeeding day on
which such stock transfer books are open; provided further, however, that such conversion shall be at the Conversion Price in effect on the Conversion Date as if the stock transfer books of Company had not been closed. Upon conversion of a
Security, such person shall no longer be a Holder of such Security. No payment or adjustment will be made for dividends or distributions on shares of Common Stock issued upon conversion of a Security. 
  
 Securities so surrendered for conversion (in whole or in part) 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 (excluding Securities or portions thereof which

are subject to purchase following a Change of Control on a date during the period beginning at the close of business on a regular record date and ending at
the opening of business on the first Business Day after the next succeeding interest payment date, or if such interest payment date is not a Business Day, the second such Business Day) shall also be accompanied by payment in funds acceptable to the
Company in an amount equal to the interest payable on such interest payment date on the principal amount of such Security then being converted, and such interest shall be payable to such registered Holder notwithstanding the conversion of such
Security, subject to the provisions of this Indenture relating to the payment of defaulted interest by the Company. Except as otherwise provided in this Section 5.02, no payment or adjustment will be made for accrued interest on a converted
Security. If the Company defaults in the payment of interest payable on such interest payment date, the Company shall promptly repay such funds to such Holder. 
  

Nothing in this Section shall affect the right of a Holder in whose name any Security is registered at the close of business on a record date to
receive the interest payable on such Security on the related interest payment date in accordance with the terms of this Indenture and the Securities. If a Holder converts more than one Security at the same time, the number of shares of Common Stock
issuable upon the conversion shall be based on the aggregate principal amount of Securities converted. 
  
 Upon surrender of a Security that is converted in part, the Company shall execute, and the Trustee shall authenticate and deliver to the Holder, a new
Security equal in principal amount to the unconverted portion of the Security surrendered. 
  
 
SECTION 5.03. Fractional Shares. The Company will not issue fractional shares of Common Stock upon conversion of Securities. In lieu thereof, the Company will pay an amount in cash based upon the Closing Price of
the Common Stock on the Trading Day immediately prior to the Conversion Date. 
  
 
SECTION 5.04. Taxes on Conversion. If a Holder converts a Security, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue of shares of Common Stock upon such conversion.
However, the Holder shall pay any such tax which is due because the Holder requests the shares to be issued in a name other than the Holder’s name. The Conversion Agent may refuse to deliver the certificate representing the Common Stock being
issued in a name other than the Holder’s name until the Conversion Agent receives a sum sufficient to pay any tax which will be due because the shares are to be issued in a name other than the Holder’s name. Nothing herein shall preclude
any tax withholding required by law or regulation. 
  
 
SECTION 5.05. Company To Provide Stock. The Company shall, prior to issuance of any Securities hereunder, and from time to time as may be necessary, reserve, out of its authorized but unissued Common Stock,
a sufficient number of shares of Common Stock to permit the conversion of all outstanding Securities into shares of Common Stock. 






Table of Contents



 31 
  

 All shares of Common Stock delivered upon conversion of the Securities shall be newly issued shares,
shall be duly authorized, validly issued, fully paid and nonassessable and shall be free from preemptive rights and free of any lien or adverse claim. 
  
 The Company will endeavor promptly to comply with all federal and state securities laws regulating the offer and delivery of shares of Common Stock upon
conversion of Securities, if any, and will list or cause to have quoted such shares of Common Stock on each national securities exchange or on The Nasdaq National Market or other over-the-counter market or such other market on which the Common Stock
is then listed or quoted; provided, however, that if rules of such automated quotation system or exchange permit the Company to defer the listing of such Common Stock until the first conversion of the Securities into Common Stock in
accordance with the provisions of this Indenture, the Company covenants to list such Common Stock issuable upon conversion of the Securities in accordance with the requirements of such automated quotation system or exchange at such time. 

 
 
SECTION 5.06. Adjustment of Conversion Price. The conversion price as stated in paragraph 6 of the Securities (the “Conversion Price”) shall be adjusted from time to time by the Company as follows:

  
 (a) In case the Company shall (i) pay a
dividend on its Common Stock in shares of Common Stock, (ii) make a distribution on its Common Stock in shares of Common Stock, (iii) subdivide its outstanding Common Stock into a greater number of shares, or (iv) combine its outstanding Common
Stock into a smaller number of shares, the Conversion Price in effect immediately prior thereto shall be adjusted so that the Holder of any Security thereafter surrendered for conversion shall be entitled to receive that number of shares of Common
Stock which it would have owned had such Security been converted immediately prior to the happening of such event. An adjustment made pursuant to this subsection (a) shall become effective immediately after the record date in the case of a dividend
or distribution and shall become effective immediately after the effective date in the case of subdivision or combination. 
  
 (b) In case the Company shall issue rights or warrants to all or substantially all holders of its Common Stock entitling them (for a
period commencing no earlier than the record date described below and expiring not more than 60 days after such record date) to subscribe for or purchase shares of Common Stock (or securities convertible into Common Stock) at a price per share (or
having a conversion price per share) less than the Current Market Price Per Share of Common Stock on the record date for the determination of stockholders entitled to receive such rights or warrants, the Conversion Price in effect immediately prior
thereto shall be adjusted so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to such record date by a fraction of which (x) the numerator shall be the number of shares of Common Stock
outstanding on such record date plus the number of shares which the aggregate offering price of the total number of shares of 







Table of Contents



 32 
  

 
Common Stock so offered (or the aggregate conversion price of the convertible securities so offered, which shall be determined by multiplying the number of
shares of Common Stock issuable upon conversion of such convertible securities by the conversion price per share of Common Stock pursuant to the terms of such convertible securities) would purchase at the Current Market Price Per Share of Common
Stock on such record date, and of which (y) the denominator shall be the number of shares of Common Stock outstanding on such record date plus the number of additional shares of Common Stock offered (or into which the convertible securities so
offered are convertible). Such adjustment shall be made successively whenever any such rights or warrants are issued, and shall become effective immediately after such record date. If at the end of the period during which such rights or warrants are
exercisable not all rights or warrants shall have been exercised, the adjusted Conversion Price shall be immediately readjusted to what it would have been based upon the number of additional shares of Common Stock actually issued (or the number of
shares of Common Stock issuable upon conversion of convertible securities actually issued). 
  
 (c) In case the Company shall distribute to all or substantially all holders of its Common Stock any shares of capital stock of the
Company (other than Common Stock), evidences of indebtedness or other non-cash assets (including securities of any person other than the Company but excluding (1) dividends or distributions paid in cash or (2) dividends or distributions referred to
in subsection (a) of this Section 5.06), or shall distribute to all or substantially all holders of its Common Stock rights or warrants to subscribe for or purchase any of its securities (excluding those rights and warrants referred to in subsection
(b) of this Section 5.06 and also excluding the distribution of rights to all holders of Common Stock pursuant to the adoption of a stockholders’ rights plan), then in each such case the Conversion Price shall be adjusted so that the same shall
equal the price determined by multiplying the current Conversion Price by a fraction of which the numerator shall be the Current Market Price Per Share of the Common Stock on the record date mentioned below less the fair market value on such record
date (as reasonably determined in good faith by the Board of Directors of the Company, whose determination shall be conclusive evidence of such fair market value and which shall be evidenced by an Officers’ Certificate delivered to the Trustee)
of the portion of the capital stock, evidences of indebtedness or other non-cash assets so distributed or of such rights or warrants applicable to one share of Common Stock (determined on the basis of the number of shares of Common Stock outstanding
on the record date), and of which the denominator shall be the Current Market Price Per Share of the Common Stock on such record date. Such adjustment shall be made successively whenever any such distribution is made and shall become effective
immediately after the record date for the determination of shareholders entitled to receive such distribution. 
  
 (d) In case the Company shall, by dividend or otherwise, at any time distribute (a “Triggering Distribution”) to all or
substantially all holders of its Common Stock cash in an aggregate amount that, together with the aggregate amount of (i) any cash and the fair market value (as reasonably determined in 







Table of Contents

good faith by the Board of Directors of the Company, whose determination shall be conclusive evidence thereof and which shall be evidenced by an
Officers’ Certificate delivered to the Trustee) of any other consideration payable in respect of any tender offer by the Company or a Subsidiary of the Company for Common Stock consummated within the 12 months preceding the date of payment of
the Triggering Distribution and in respect of which no Conversion Price adjustment pursuant to this Section 5.06 has been made and (ii) all other cash distributions to all or substantially all holders of its Common Stock made within the 12 months
preceding the date of payment of the Triggering Distribution and in respect of which no Conversion Price adjustment pursuant to this Section 5.06 has been made, exceeds an amount equal to 10.0% of the product of the Current Market Price Per Share of
Common Stock on the Business Day (the “Determination Date”) immediately preceding the day on which such Triggering Distribution is declared by the Company multiplied by the number of shares of Common Stock outstanding on the Determination
Date (excluding shares held in the treasury of the Company), the Conversion Price shall be reduced so that the same shall equal the price determined by multiplying such Conversion Price in effect immediately prior to the Determination Date by a
fraction of which the numerator shall be the Current Market Price Per Share of the Common Stock on the Determination Date less the sum of the aggregate amount of cash and the aggregate fair market value (as reasonably determined in good faith by the
Board of Directors of the Company, whose determination shall be conclusive evidence of such fair market value and which shall be evidenced by an Officers’ Certificate delivered to the Trustee) of any such other consideration so distributed,
paid or payable within such 12 months (including, without limitation, the Triggering Distribution) applicable to one share of Common Stock (determined on the basis of the number of shares of Common Stock outstanding on the Determination Date) and
the denominator shall be such Current Market Price Per Share of the Common Stock on the Determination Date, such reduction to become effective immediately prior to the opening of business on the day following the date on which the Triggering
Distribution is paid. 
  
 (e) (1) In case any
tender offer made by the Company for Common Stock shall expire and such tender offer (as amended upon the expiration thereof) shall involve the payment of aggregate consideration in an amount (determined as the sum of the aggregate amount of cash
consideration and the aggregate fair market value (as reasonably determined in good faith by the Board of Directors of the Company, whose determination shall be conclusive evidence thereof and which shall be evidenced by an Officers’
Certificate delivered to the Trustee) of any other consideration) that, together with the aggregate amount of (i) any cash and the fair market value (as reasonably determined in good faith by the Board of Directors of the Company, whose
determination shall be conclusive evidence thereof and which shall be evidenced by an Officers’ Certificate delivered to the Trustee) of any other consideration payable in respect of any other tender offers by the Company or any Subsidiary of
the Company for Common Stock consummated within the 12 months preceding the date of the Expiration Date (as defined below) and in respect of which no Conversion Price adjustment pursuant 







Table of Contents



 34 
  

 
to this Section 5.06 has been made and (ii) all cash distributions to all or substantially all holders of its Common Stock made within the 12 months
preceding the Expiration Date and in respect of which no Conversion Price adjustment pursuant to this Section 5.06 has been made, exceeds an amount equal to 10.0% of the product of the Current Market Price Per Share of Common Stock as of the last
date (the “Expiration Date”) tenders could have been made pursuant to such tender offer (as it may be amended) (the last time at which such tenders could have been made on the Expiration Date is hereinafter sometimes called the
“Expiration Time”) multiplied by the number of shares of Common Stock outstanding (including tendered shares but excluding any shares held in the treasury of the Company) at the Expiration Time, then, immediately prior to the opening of
business on the day after the Expiration 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 the Expiration Date by
a fraction of which the numerator shall be the product of the number of shares of Common Stock outstanding (including tendered shares but excluding any shares held in the treasury of the Company) at the Expiration Time multiplied by the Current
Market Price Per Share of the Common Stock on the Trading Day next succeeding the Expiration Date and the denominator shall be the sum of (x) the aggregate consideration (determined as aforesaid) 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 and excluding any shares held in the treasury of the Company) at the Expiration Time and the Current Market Price Per Share of Common Stock on the Trading
Day next succeeding the Expiration Date, such reduction to become effective immediately prior to the opening of business on the day following the Expiration Date. 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 or all such purchases or any or all such purchases are rescinded, the Conversion Price shall again be adjusted to be the Conversion Price which would have
been in effect based upon the number of shares actually purchased. If the application of this Section 5.06(e) 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 5.06(e). 
  
 (2) For purposes of Section
5.06(d) and 5.06(e), the term “tender offer” shall mean and include both tender offers and exchange offers (within the meaning of U.S. Federal securities laws), all references to “purchases” of shares in tender offers (and all
similar references) shall mean and include both the purchase of shares in tender offers and the acquisition of shares pursuant to exchange offers, and all references to “tendered shares” (and all similar references) shall mean and include
shares tendered in both tender offers and exchange offers.

 (f) For the purpose of any computation under subsections (b), (c), (d) and (e) of this
Section 5.06, the current market price per share of Common Stock (the “Current Market Price Per Share”) on any date shall be deemed to be the average of the daily Closing Prices for the 30 consecutive Trading Days commencing 45 Trading
Days before (i) the Determination Date or the Expiration Date, as the case may be, with respect to distributions or tender offers under subsection (e) of this Section 5.06 or (ii) the record date with respect to distributions, issuances or other
events requiring such computation under subsection (b), (c) or (d) of this Section 5.06. The Closing Price for each day (the “Closing Price”) shall be the last reported sales price or, in case no such reported sale takes place on such
date, the average of the reported closing bid and asked prices in either case on The New York Stock Exchange (the “NYSE”) or the Nasdaq National Market (the “NNM”), as applicable, or, if the Common Stock is not listed or admitted
to trading on the NYSE or the NNM, the principal national securities exchange or quotation system on which the Common Stock is quoted or listed or admitted to trading or, if not quoted or listed or admitted to trading on any national securities
exchange or quotation system, the closing sales price or, in case no reported sale takes place, the average of the closing bid and asked prices, as furnished by any two members of the National Association of Securities Dealers, Inc. selected from
time to time by the Company for that purpose. If no such prices are available, the Current Market Price Per Share shall be the fair value of a share of Common Stock (as reasonably determined in good faith by the Board of Directors of the Company,
whose determination shall be conclusive evidence of such fair market value and which shall be evidenced by an Officers’ Certificate delivered to the Trustee). 
  
 (g) In any case in which this Section 5.06 shall require that an adjustment be made following a record date
or a Determination Date or Expiration Date, as the case may be, established for purposes of this Section 5.06, the Company may elect to defer (but only until five Business Days following the filing by the Company with the Trustee of the certificate
described in Section 5.09) issuing to the Holder of any Security converted after such record date or Determination Date or Expiration Date the shares of Common Stock and other capital stock of the Company issuable upon such conversion over and above
the shares of Common Stock and other capital stock of the Company issuable upon such conversion only on the basis of the Conversion Price prior to adjustment; and, in lieu of the shares the issuance of which is so deferred, the Company shall issue
or cause its transfer agent to issue due bills or other appropriate evidence prepared by the Company of the right to receive such shares. If any distribution in respect of which an adjustment to the Conversion Price is required to be made as of the
record date or Determination Date or Expiration Date therefor is not thereafter made or paid by the Company for any reason, the Conversion Price shall be readjusted to the Conversion Price which would then be in effect if such record date had not
been fixed or such effective date or Determination Date or Expiration Date had not occurred.

SECTION 5.07. No Adjustment. No adjustment in the Conversion Price shall be required unless the adjustment would require an increase or decrease of at least 1% in the Conversion Price as last adjusted; provided,
however, that any adjustments which by reason of this Section 5.07 are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Article 5 shall be made to the nearest cent or
to the nearest one-hundredth of a share, as the case may be. 
  
 No adjustment need be made for issuances of Common Stock pursuant to a Company plan for reinvestment of dividends or interest or for a change in the par value or a change to no par value of the Common Stock. 
  
 To the extent that the Securities become convertible into the right to
receive cash, no adjustment need be made thereafter as to the cash. Interest will not accrue on the cash. 
  
 
SECTION 5.08. Adjustment for Tax Purposes. The Company shall be entitled to make such reductions in the Conversion Price, in addition to those required by Section 5.06, as it in its discretion shall determine to
be advisable in order that any stock dividends, subdivisions of shares, distributions of rights to purchase stock or securities or distributions of securities convertible into or exchangeable for stock hereafter made by the Company to its
stockholders shall not be taxable. 
  
 
SECTION 5.09. Notice of Adjustment. Whenever the Conversion Price or conversion privilege is adjusted, the Company shall promptly mail to Securityholders a notice of the adjustment and file with the Trustee an
Officers’ Certificate briefly stating the facts requiring the adjustment and the manner of computing it. Unless and until the Trustee shall receive an Officers’ Certificate setting forth an adjustment of the Conversion Price, the Trustee
may assume without inquiry that the Conversion Price has not been adjusted and that the last Conversion Price of which it has knowledge remains in effect. 
  
 
SECTION 5.10. Notice of Certain Transactions. In the event that: 
  
 (1) the Company takes any action which would require an adjustment in the Conversion Price; 
  
 (2) the Company consolidates or merges with or into, or
transfers all or substantially all of its property and assets to, another corporation or another corporation merges into the Company and, in each such case, stockholders of the Company must approve the transaction; or 
  
 (3) there is a dissolution or liquidation of the Company,

  
 the Company shall mail to Holders and file with the Trustee a notice stating
the proposed record or effective date, as the case may be. The Company shall mail the notice at least ten days before such date. Failure to mail such notice or any defect therein shall not

affect the validity of any transaction referred to in clause (1), (2) or (3) of this Section 5.10. 
  
 
SECTION 5.11. Effect of Reclassification, Consolidation, Merger or Sale on Conversion Privilege. If any of the following shall occur, namely: (a) any reclassification or change of shares of Common Stock issuable
upon conversion of the Securities (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination, or any other change for which an adjustment is provided in
Section 5.06); (b) any consolidation or merger or combination to which the Company is a party other than a merger in which the Company is the continuing corporation and which does not result in any reclassification of, or change (other than in par
value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination) in, outstanding shares of Common Stock; or (c) any sale, conveyance, transfer or lease of the property and assets of the
Company as an entirety or substantially as an entirety, directly or indirectly, to any Person, then the Company, or such successor, purchasing, transferee or leasing Person, as the case may be, shall, as a condition precedent to such
reclassification, change, combination, consolidation, merger, sale, conveyance, transfer or lease, execute and deliver to the Trustee a supplemental indenture providing that the Holder of each Security then outstanding shall have the right to
convert such Security into the kind and amount of shares of stock and other securities and property (including cash) receivable upon such reclassification, change, combination, consolidation, merger, sale, conveyance, transfer or lease by a holder
of the number of shares of Common Stock deliverable upon conversion of such Security immediately prior to such reclassification, change, combination, consolidation, merger, sale, conveyance, transfer or lease. Such supplemental indenture shall
provide for adjustments of the Conversion Price which shall be as nearly equivalent as may be practicable to the adjustments of the Conversion Price provided for in this Article 5. If, in the case of any such consolidation, merger, combination,
sale, conveyance, transfer or lease the stock or other securities and property (including cash) receivable thereupon by a holder of Common Stock include shares of stock or other securities and property of a Person other than the successor,
purchasing, transferee or leasing Person, as the case may be, in such consolidation, merger, combination, sale, conveyance, transfer or lease, then such supplemental indenture shall also be executed by such other Person and shall contain such
additional provisions to protect the interests of the Holders of the Securities as the Board of Directors of the Company shall reasonably consider necessary by reason of the foregoing. The provisions of this Section 5.11 shall similarly apply to
successive reclassifications, changes, combinations, consolidations, mergers, sales, conveyances, transfers or leases. 
  
 In the event the Company shall execute a supplemental indenture pursuant to this Section 5.11, the Company shall promptly file with the Trustee (x) an
Officers’ Certificate briefly stating the reasons therefor, the kind or amount of shares of stock or other securities or property (including cash) receivable by Holders of the Securities upon the conversion of their Securities after any such
reclassification, change, combination, consolidation, merger, sale, conveyance, transfer or lease, any adjustment to be made with respect thereto and that all conditions precedent have been complied with and (y) an 







Table of Contents



 38 
  

 
Opinion of Counsel that all conditions precedent have been complied with, and shall promptly mail notice thereof to all Holders. 
  
 
SECTION 5.12. Trustee’s Disclaimer. The Trustee shall have no duty to determine when an adjustment under this Article 5 should be made, how it should be made or what such adjustment should be, but may accept
as conclusive evidence of that fact or the correctness of any such adjustment, and shall be protected in relying upon, an Officers’ Certificate including the Officers’ Certificate with respect thereto which the Company is obligated to file
with the Trustee pursuant to Section 5.09. The Trustee makes no representation as to the validity or value of any securities or assets issued upon conversion of Securities, and the Trustee shall not be responsible for the Company’s failure to
comply with any provisions of this Article 5. 
  
 The Trustee
shall not be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture executed pursuant to Section 5.11, but may accept as conclusive evidence of the correctness thereof, and shall be fully
protected in relying upon, the Officers’ Certificate with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 5.11. 
  


SECTION 5.13. Voluntary Reduction. The Company from time to time may voluntarily reduce the Conversion Price by any amount for any period of time if the period is at least 20 days and if the reduction is
irrevocable during the period if the Board of Directors of the Company determines that such reduction would be in the best interests of the Company, and the Company provides 15 days’ prior notice of any voluntary reduction in the Conversion
Price; provided, however, that in no event may the Company reduce the Conversion Price to be less than the par value of a share of Common Stock, and provided, further, that no such decrease shall be taken into account for purposes of the
determination of whether the Closing Price of the Common Stock exceeds 105% of the Conversion Price pursuant to Section 4.07. 
  
 ARTICLE 6 
  
 Successor Companies 
  
 
SECTION 6.01. When Company May Merge or Transfer Assets. The Company may not consolidate, combine with or merge with or into any other Person, in a transaction in which it is not the surviving corporation, or
sell, convey, transfer or lease its properties and assets as an entirety or substantially as an entirety to any successor Person unless: 
  
 (1) the successor, purchasing, transferring or leasing Person, if any, is a corporation, limited liability company, partnership, trust or
other entity organized and existing under the laws of the United States, any State thereof or the District of Columbia (the “Successor Person”) and expressly assumes the obligations of the Company under this Indenture by a supplemental
indenture as provided in Section 5.11;

 39 
  

 (2) immediately after giving effect to such transaction, and treating any Indebtedness
which becomes an Obligation of the Company or any Subsidiary of the Company as a result of such transaction as having been Incurred by it at the time of the transaction, no Default or Event of Default shall have occurred and be continuing; and

  
 (3) the Company shall have delivered to the
Trustee an Officers’s Certificate and an Opinion of Counsel, each stating that such consolidation, combination, merger, conveyance, sale, transfer or lease and such supplemental indenture (if any) comply with this Indenture. 
  
 The Successor Person shall be the successor to the Company and shall succeed
to, and be substituted for, and may exercise every right and power of the Company under this Indenture, and the predecessor Company, except in the case of a lease, shall be automatically released from its obligations under this Indenture and the
Securities. 
  
 ARTICLE 7 
  
 Defaults and Remedies 
  
 
SECTION 7.01. Events of Default. An “Event of Default” occurs if: 
  
 (1) the Company defaults in any payment of interest on any Security when the same becomes due and payable, whether or not such payment
shall be prohibited by Article 11, and such default continues for a period of 30 days; 
  
 (2) the Company (i) defaults in the payment of the principal of or premium, if any, on any Security when the same becomes due and payable
at its Stated Maturity, upon declaration of acceleration or otherwise, whether or not such payment shall be prohibited by Article 11 or (ii) fails to purchase Securities when required pursuant to this Indenture or the Securities, whether or not such
purchase shall be prohibited by Article 11; 
  
 (3) the Company fails to comply for 30 days after the notice specified below with any of its obligations pursuant to Sections 4.07, 4.08, 4.09, 4.10 and 4.11 (other than its obligation to purchase Securities properly submitted for
purchase); 
  
 (4) the Company fails to comply
with its obligations under Section 6.01; 
  
 (5)
the Company fails to comply with any of its agreements in the Securities or this Indenture (other than those referred to in clauses (1) through (4) above) and such failure continues for 60 days after the notice specified below; 
  
 (6) the Company pursuant to or within the meaning of any
Bankruptcy Law: 






Table of Contents



 40 
  

 (A) commences a voluntary case; 
  
 (B) consents to the entry of an order for relief against it
in an involuntary case; 
  
 (C) consents to the
appointment of a Custodian of it or for a substantial part of its property; or 
  
 (D) makes a general assignment for the benefit of its creditors; 
  
 (7) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: 
  
 (A) is for relief against the Company in an involuntary case;

  
 (B) appoints a Custodian of the Company or
for all or substantially all of its property; or 
  
 (C) orders the winding up or liquidation of the Company; 
  
 and the order or decree remains unstayed and in effect for 60 days (together with Clause (6), the “bankruptcy provisions”); or 
  
 (8) Indebtedness of the Company is not paid within any applicable grace period after final maturity or is
accelerated by the holders thereof because of a default and the total amount of such Indebtedness unpaid or accelerated exceeds $15.0 million (the “cross acceleration provision”). 
  
 However, a default under clauses (3) or (5) will not constitute an Event of Default until the
Trustee or the holders of 25% in principal amount of the outstanding Securities notify the Company of the default and the Company does not cure such default within the time specified after receipt of such notice. The notice given pursuant to this
Section 7.01 must specify the Default, demand that it be remedied and state that such notice is a “Notice of Default.” 
  
 The Company shall deliver to the Trustee, within 30 days after the occurrence thereof, written notice in the form of an Officers’ Certificate of any
Event of Default under clause (8) and any event which with the giving of notice or the lapse of time would become an Event of Default under clause (3) or (5), its status and what action the Company is taking or proposes to take with respect thereto.

  
 The foregoing will constitute Events of Default whatever the
reason for any such Event of Default and whether it is voluntary or involuntary or is 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.

  
 The term “Bankruptcy Law” means Title 11, United
States Code, or any similar Federal, state or foreign law for the relief of debtors. The term “Custodian”

means any receiver, trustee, assignee, liquidator, custodian or similar official under any Bankruptcy Law. 
  
 
SECTION 7.02. Acceleration. If an Event of Default (other than an Event of Default specified in Section 7.01(6) or (7) (in either case) with respect to the Company) occurs and is continuing, the Trustee by notice
to the Company, or the Holders of at least 25% in principal amount of the Securities by notice to the Company and the Trustee, may declare the principal of and accrued but unpaid interest on all the Securities to be due and payable. Upon such a
declaration, such principal and interest shall be due and payable immediately. If an Event of Default specified in Section 7.01(6) or (7) occurs, the principal of and interest on all the Securities shall ipso facto become and be immediately due and
payable without any declaration or other act on the part of the Trustee or any Securityholders. The Holders of a majority in principal amount of the outstanding Securities by notice to the Trustee may rescind an acceleration with respect to the
Securities and its consequences if the rescission would not conflict with any judgment or decree, if all existing Events of Default have been cured or waived except nonpayment of principal or interest that has become due solely because of
acceleration and all payments due to the Trustee under Section 8.07 of this Indenture have been made. No such rescission shall affect any subsequent Default or impair any right consequent thereto. Any payment by the Company pursuant to this section
is subject to Article 11. 
  
 
SECTION 7.03. Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of or interest on the Securities or to enforce the
performance of any provision of the Securities or this Indenture. 
  
 The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Securityholder in exercising any right or remedy accruing
upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative. 
  
 
SECTION 7.04. Waiver of Past Defaults. The Holders of a majority in principal amount of the Securities by notice to the Trustee may waive an existing Default and its consequences except (1) a Default in the
payment of the principal of or interest on a Security or (2) a Default in respect of a provision that under Section 10.02 cannot be amended without the consent of each Securityholder affected. When a Default is waived, it is deemed cured, but no
such waiver shall extend to any subsequent or other Default or impair any consequent right. 
  
 
SECTION 7.05. Control by Majority. The Holders of a majority in principal amount of the outstanding Securities may direct the time, method and place of conducting any proceeding for any remedy available to the

the rights of other Securityholders or would

such action.

 (2) the Holders of at least 25% in principal amount of the outstanding Securities make a written request to the Trustee to pursue the
remedy; 
  
 (3) such Holder or Holders offer to

 (5) the Holders of a majority in principal
amount of the Securities do not give the Trustee a direction inconsistent with the request during such 60-day period. 
  
 A Securityholder may not use this Indenture to prejudice the rights of another Securityholder or to obtain a preference or priority over another
Securityholder. 
  
 
SECTION 7.07. Rights of Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of and interest on the Securities held by such
Holder, on or after the respective due dates expressed in the Securities, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder. 

 
 
SECTION 7.08. Collection Suit by Trustee. If an Event of Default specified in Section 7.01(1) or (2) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust
against the Company for the whole amount then due and owing (together with interest on any unpaid interest to the extent lawful) and the amounts provided for in Section 8.07. 
  
 
SECTION 7.09. Trustee May File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and the

participating as a member of any official committee of creditors, as it reasonably deems necessary or advisable, and, unless prohibited by law or applicable regulations, may vote on behalf of the Holders in any election of a trustee in bankruptcy or
other Person performing similar functions. The Trustee shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims, and any Custodian in any such judicial proceeding is
hereby authorized by each Holder to make payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 8.07.

discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in
the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 7.07 or a suit by Holders of more than 10% in

furnished to the Trustee, the Trustee shall examine such certificates and opinions to determine whether or not they conform to the requirements of this Indenture.

liability is not reasonably assured to it.

SECTION 8.03. Individual Rights of Trustee. 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 its Affiliates with the same
rights it would have if it were not Trustee. Any Paying Agent, Registrar, co-registrar or co-paying agent may do the same with like rights. However, the Trustee must comply with Sections 8.10 and 8.11. 
  
 
SECTION 8.04. Trustee’s Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Securities, it shall not be accountable for the
Company’s use of the proceeds from the Securities, and it shall not be responsible for any statement of the Company in the Indenture or in any document issued in connection with the sale of the Securities or in the Securities other than the
Trustee’s certificate of authentication. 
  
 
SECTION 8.05. Notice of Defaults. If a Default occurs and is continuing and if it is actually known to the Trustee, or upon written notice from the Company or any Securityholder or upon a Payment Default, the
Trustee shall mail to each Securityholder notice of the Default within 90 days after it occurs. Except in the case of a Default in payment of principal of or interest on any Security (including payments pursuant to the mandatory redemption
provisions of such Security, if any), the Trustee may withhold the notice if and so long as a committee of its Trust Officers in good faith determines that withholding the notice is in the interests of Securityholders. 
  
 
SECTION 8.06. Reports by Trustee to Holders. As promptly as practicable after each May 15 beginning with May 15, 2004, and in any event within 60 days of each May 15, the Trustee shall mail to each Securityholder
a brief report dated as of May 15 of each year that complies with TIA § 313(a). The Trustee also shall comply with TIA § 313(b). 
  
 A copy of each report at the time of its mailing to Securityholders shall be filed with the SEC and each stock exchange (if any) on which the Securities
are listed. The Company agrees to notify promptly the Trustee whenever the Securities become listed on any stock exchange and of any delisting thereof. 
  
 
SECTION 8.07. Compensation and Indemnity. The Company shall pay to the Trustee from time to time reasonable compensation for its services. The Trustee’s compensation shall not be limited by any law on
compensation of a trustee of an express trust. The Company shall reimburse the Trustee promptly upon request for all reasonable out-of-pocket expenses, disbursements and advances incurred or made by it, including costs of collection, in addition to
the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and experts. The Company shall indemnify the Trustee against any
and all loss, liability or expense (including reasonable attorneys’ fees) incurred by it in connection with the administration of this trust and the performance of its duties hereunder, including the costs and expenses of enforcing this
Indenture (including this Section 8.07) against the Company and defending itself against any claim (whether asserted by any Securityholder or any other Person) or liability in 







Table of Contents

connection with the exercise or performance of any of its powers or duties hereunder. The Trustee shall notify the Company promptly of any claim for which it
may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder unless such failure prejudices the Company. The Company shall defend the claim and the Trustee may have separate counsel
and the Company shall pay the fees and expenses of such counsel. The Company need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee through the Trustee’s own wilful misconduct, negligence or
bad faith. 
  
 The Company need not pay for any settlement made by
the Trustee without the Company’s consent, such consent not to be unreasonably withheld. 
  
 To secure the Company’s payment obligations in this Section, the Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee other than money or property held in
trust to pay principal of and interest on particular Securities. 
  
 The Company’s payment obligations, and the lien granted to the Trustee, pursuant to this Section shall survive the discharge of this Indenture. When the Trustee incurs expenses or renders services after the occurrence of a Default
specified in Section 7.01(6) or (7) with respect to the Company, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under the
Bankruptcy Law. 
  
 
SECTION 8.08. Replacement of Trustee. The Trustee may resign at any time by so notifying the Company. The Holders of a majority in principal amount of the Securities may remove the Trustee by so notifying the
Trustee and may appoint a successor Trustee. The Company shall remove the Trustee if: 
  
 (1) the Trustee fails to comply with Section 8.10; 
  
 (2) the Trustee is adjudged bankrupt or insolvent; 
  
 (3) a receiver or other public officer takes charge of the
Trustee or its property; or 
  
 (4) the Trustee
otherwise becomes incapable of acting. 
  
 If the Trustee resigns,
is removed by the Company or by the Holders of a majority in principal amount of the outstanding Securities and such Holders do not reasonably promptly appoint a successor Trustee, or if a vacancy exists in the office of Trustee for any reason (the
Trustee in such event being referred to herein as the retiring Trustee), the Company shall promptly appoint 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 successor Trustee shall mail a

notice of its succession to Securityholders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee,
provided that the amounts owing to the Trustee hereunder have been paid and subject to the lien provided for in Section 8.07. 
  
 If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee or the Holders of 10% in
principal amount of the Securities may petition any court of competent jurisdiction for the appointment of a successor Trustee. 
  
 If the Trustee fails to comply with Section 8.10, any Securityholder may petition any court of competent jurisdiction for the removal of the Trustee and
the appointment of a successor Trustee. 
  
 Notwithstanding the
replacement of the Trustee pursuant to this Section, the Company’s obligations under Section 8.07 shall continue for the benefit of the retiring Trustee. 
  


SECTION 8.09. Successor Trustee by Merger. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation or banking
association, the resulting, surviving or transferee corporation without any further act shall be the successor Trustee provided that such successor shall be eligible and qualified under Section 8.10. 
  
 In case at the time such successor or successors by merger, conversion or
consolidation to the Trustee shall succeed to the trusts created by this Indenture any of the Securities shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any
predecessor trustee, and deliver such Securities so authenticated; and in case at that time any of the Securities shall not have been authenticated, any successor to the Trustee may authenticate such Securities either in the name of any predecessor
hereunder or in the name of the successor to the Trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Securities or in this Indenture provided that the certificate of the Trustee shall have.

  
 
SECTION 8.10. Eligibility; Disqualification. The Trustee shall at all times satisfy the requirements of TIA § 310(a). The Trustee shall have a combined capital and surplus of at least $50,000,000 as set forth
in its most recent published annual report of condition. The Trustee shall comply with TIA § 310(b); provided, however, that there shall be excluded from the operation of TIA § 310(b)(1) any indenture or indentures under
which other securities or certificates of interest or participation in other securities of the Company are outstanding if the requirements for such exclusion set forth in TIA § 310(b)(1) are met. 
  
 
SECTION 8.11. Preferential Collection of Claims Against Company. The Trustee shall comply with TIA § 311(a), excluding any creditor relationship listed in TIA

provided for and except as further provided below), and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when (a) either;

(other than (x) Securities which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 2.10 and (y) Securities for whose payment money has therefore been deposited in trust and thereafter repaid to the
Company as provided in Section 9.03, have been delivered to the Trustee for cancellation; or

and payable at the Stated Maturity within 90 days and the Company has irrevocably deposited or caused to be irrevocably deposited with the Trustee or a Paying Agent (other than the Company or any of its Affiliates) as trust funds in trust for the
purpose cash in an amount sufficient to pay and discharge the entire indebtedness on such Securities not theretofore delivered to the Trustee for cancellation, for principal and interest to the date of such deposit (in the case of Securities which
have become due and payable) or to the Stated Maturity; 
  
 (b)
the Company has paid or caused to be paid all other sums payable hereunder by the Company; and 
  
 (c) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this

2.03, 2.05, 2.06, 2.07, 2.08, 2.10, 4.02, 4.04, 4.06, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, Article 5, Article 6, and this Article 9 shall survive until the Securities have been paid in full.

Company upon request any money held by them for the payment of principal or interest that remains unclaimed for two years, and, thereafter, Securityholders entitled to the money must look to the Company for payment as general creditors. 

 
 
SECTION 9.04. Reinstatement. If the Trustee or any Paying Agent is unable to apply any money in accordance with Section 9.02 by reason of any legal proceeding or by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s obligations under this Indenture and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to
Section 9.01 until such time as the Trustee or such Paying Agent is permitted to apply all such money in accordance with Section 9.02; provided, however, that if the Company has made any payment of the principal of or interest on any
Securities because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive any such payment from the money held by the Trustee or such Paying Agent.

 (7) to add to covenants of the Company for
the benefit of the Securityholders or to surrender any right or power conferred upon the Company; and 
  
 (8) to make any change that does not adversely affect the rights of any Securityholder, including providing for the sale and resale of the
Securities under Regulation S of the Securities Act. 
  
 After an
amendment under this Section becomes effective, the Company shall mail to Securityholders a notice briefly describing such amendment. The failure to give such notice to all Securityholders, or any defect therein, shall not impair or affect the
validity of an amendment under this Section. 
  
 
SECTION 10.02. With Consent of Holders. The Company and the Trustee may amend this Indenture or the Securities without notice to any Securityholder but with the written consent of the Holders of at least a
majority in principal amount of the Securities then outstanding (including consents obtained in connection with a tender offer or exchange for the Securities). However, without the written consent of each Securityholder affected thereby, an
amendment may not: 
  
 (a) reduce the rate of or
extend the time for payment of interest on any Security; 
  
 (b) reduce the principal amount of, or any premium on, or extend the Stated Maturity of, any Security;

whose Holders must consent to a modification or amendment of this Indenture; and 
  
 (j) modify any of the provisions of this Section or Section 7.04, except to increase any such percentage or to provide that specified
additional provisions of this Indenture cannot be modified or waived without the consent of the Holder of each outstanding Security affected thereby. 
  
 It shall not be necessary for the consent of the Holders under this Section 10.02 to approve the particular form of any proposed amendment, supplement or
waiver, but it shall be sufficient if such consent approves the substance thereof. 
  
 After an amendment, supplement or waiver under this Section 10.02 becomes effective, the Company shall mail to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure
of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amendment, supplement or waiver. An amendment or supplement under this Section 10.02 or under Section 10.01 may not
make any change that adversely affects the rights under Article 11 of any holder of an issue of Senior Indebtedness unless the holders of that issue, pursuant to its terms, consent to the change.

Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent or waiver is not made on the Security. However, any such Holder or subsequent Holder may revoke the consent or waiver as to such
Holder’s Security or portion of the Security if the Trustee receives the notice of revocation before the date the amendment or waiver becomes effective. After an amendment or waiver becomes effective, it shall bind every Securityholder. An
amendment or waiver becomes effective upon the execution of such amendment or waiver by the Trustee. 
  
 The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Securityholders entitled to give their consent or
take any other action described above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding the immediately preceding paragraph, those Persons who were Securityholders at such record date
(or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons continue to be Holders after such record date. No
such consent shall be valid or effective for more than 120 days after such record date.

SECTION 10.05. Notation on or Exchange of Securities. If an amendment changes the terms of a Security, the Trustee may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an
appropriate notation on the Security regarding the changed terms and return it to the Holder. Alternatively, 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 to issue a new Security shall not affect the validity of such amendment. 
  


SECTION 10.06. Trustee To Sign Amendments. The Trustee shall sign any amendment authorized pursuant to this Article 10 if the amendment does not adversely affect the rights, duties, liabilities or immunities of
the Trustee. If it does, the Trustee may but need not sign it. In signing any amendment the Trustee shall be entitled to receive and (subject to Section 8.01) shall be fully protected in relying upon, an Officer’s Certificate and an Opinion of

the time frame set forth in solicitation documents relating to such consent, waiver or agreement. 
  
 ARTICLE 11 
  
 Subordination 
  
 
SECTION 11.01. Agreement To Subordinate. The Company agrees, and each Securityholder by accepting a Security agrees, that the Indebtedness evidenced by the Securities is subordinated in right of payment, to the
extent and in the manner provided in this Article 11, to the prior payment in full in cash of all Obligations with respect to Senior Indebtedness of the Company and that the subordination is for the benefit of and enforceable by the holders of such
Senior Indebtedness. All provisions of this Article 11 shall be subject to Section 11.12. 
  
 
SECTION 11.02. Liquidation, Dissolution, Bankruptcy. Upon any payment or distribution of the assets of the Company to creditors upon a total or partial liquidation or a total or partial dissolution or winding up
of the Company or upon any assignment for the benefit of creditors or marshaling of assets of the Company or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to the Company or its property, whether voluntary
or involuntary: 
  
 (1) the holders of Senior
Indebtedness of the Company shall be entitled to receive payment in full in cash of all Obligations with respect to such Senior Indebtedness (including all interest accruing subsequent to the filing of a petition

in bankruptcy at the rate provided for in the documentation with respect thereto, whether or not such interest is an allowed claim under applicable law)
before Securityholders shall be entitled to receive any payment or distribution with respect to the Securities; and 
  
 (2) until all Obligations with respect to such Senior Indebtedness are paid in full in cash, any payment or distribution to which
Securityholders would be entitled but for this Article 11 shall be made to holders of such Senior Indebtedness as their interests may appear, except that Securityholders may receive in exchange for the Securities in any proceeding of the type
described above in this Section 11.02, (x) equity securities of the Company which, in any case, do not provide any mandatory redemption or similar retirement prior to the maturity of the Securities or (y) unsecured debt securities of the Company
which are subordinated to at least the same extent as the Securities to the payment of all Senior Indebtedness of the Company and which, in any case, do not mature or become subject to a mandatory redemption obligation prior to the maturity of the
Securities. 
  
 
SECTION 11.03. Default on Senior Indebtedness. The Company may not pay (in cash, property or other assets) the principal, premium, if any, or interest on the Securities and may not repurchase or otherwise retire
any Securities (collectively, “pay the Securities”) if either of the following occurs (each, a “Payment Default”) (i) any Obligations with respect to Senior Indebtedness are not paid in full when due or (ii) any other default on
Senior Indebtedness occurs and the maturity of such Senior Indebtedness is accelerated in accordance with its terms unless, in either case, (x) the default has been cured or waived and any such acceleration has been rescinded in writing or (y) such
Senior Indebtedness has been paid in full in cash; provided, however, that the Company may pay the Securities without regard to the foregoing if the Company and the Trustee receive written notice approving such payment from the
Representative of such Senior Indebtedness. During the continuance of any default (other than a default described in clause (i) or (ii) of the preceding sentence) with respect to any Designated Senior Indebtedness pursuant to which the maturity
thereof may be accelerated immediately without further notice (except such notice as may be required to effect such acceleration) or the expiration of any applicable grace periods, the Company may not pay the Securities for a period (a “Payment
Blockage Period”) commencing upon the receipt by the Company and the Trustee of written notice (a “Blockage Notice”) of such default from the Representative of such Designated Senior Indebtedness specifying an election to effect a
Payment Blockage Period and ending 179 days thereafter (or earlier if such Payment Blockage Period is terminated (1) by written notice to the Trustee and the Company from the Person or Persons who gave such Blockage Notice, (2) because no defaults
continue in existence which would permit the acceleration of the maturities of any Designated Senior Indebtedness at such time or (3) because such Designated Senior Indebtedness has been repaid in full in cash). Unless the holders of such Designated
Senior Indebtedness or the Representative of such holders shall have accelerated the maturity of such Designated Senior Indebtedness, or any Payment Default otherwise exists, the Company may resume payments on the Securities after termination of
such Payment Blockage Period and may make any and all payments that were previously

subject to a Payment Blockage Period. The Securities shall not be subject to more than one Payment Blockage Period in any consecutive 360-day period;
provided, however that if any Blockage Notice is delivered to the Trustee by or on behalf of holders of Designated Senior Indebtedness (other than holders of the Bank Indebtedness), a Representative of holders of Bank Indebtedness may
give another Blockage Notice within such period, provided further, however, that in no event may the total number of days during which any Payment Blockage Period or Periods is in effect exceed 179 days in the aggregate during any
consecutive 360 day period, and there must be 181 days during any consecutive 360 day period during which no Payment Blockage Period is in effect. For purposes of this Section, no default or event of default which existed or was continuing on the
date of the commencement of any Payment Blockage Period with respect to the Designated Senior Indebtedness initiating such Payment Blockage Period shall be, or be made, the basis of the commencement of a subsequent Payment Blockage Period by the
Representative of such Designated Senior Indebtedness, whether or not within a period of 360 consecutive days, unless such default or event of default shall have been cured or waived for a period of not less than 90 consecutive days (it being
acknowledged and agreed that (x) any default or event of default as a result of a continued failure to meet a financial covenant or test for a period ended subsequent to the commencement of a Payment Blockage Period shall constitute a new default or
event of default, as the case may be, and shall be deemed not to be a continuing default or event of default, as the case may be, for purposes of this sentence and (y) any subsequent action which would give rise to a default or an event of default
pursuant to any provision under which a default or event of default previously existed or was continuing shall constitute a new default or event of default, as the case may be, for this purpose and shall be deemed not to be a continuing default or
event of default, as the case may be, for purposes of this sentence). 
  
 
SECTION 11.04. Acceleration of Payment of Securities. If payment of the Securities is accelerated because of an Event of Default, the Company or the Trustee shall promptly notify the holders of the Designated
Senior Indebtedness (or their Representatives) of the acceleration. If any Designated Senior Indebtedness is outstanding at the time of such acceleration, the Company may not pay the Securities until five Business Days after the Representatives of
all the issues of Designated Senior Indebtedness receive notice of such acceleration and, thereafter, may pay the Securities only if the Indenture otherwise permits payment at that time. 
  
 
SECTION 11.05. When Distribution Must Be Paid Over. If a distribution is made to Securityholders that because of this Article 11 should not have been made to them, the Securityholders who receive the distribution
shall hold it in trust for holders of Senior Indebtedness of the Company and pay it over to them as their interests may appear. 
  
 
SECTION 11.06. Subrogation. After all Senior Indebtedness of the Company is paid in full in cash and until the Securities are paid in full, Securityholders shall be subrogated to the rights of holders of such
Senior Indebtedness to receive distributions applicable to such Senior Indebtedness. A distribution made under this Article 11 to holders of such Senior Indebtedness which otherwise would have been 






Table of Contents



 56 
  

 
made to Securityholders is not, as between the Company and Securityholders, a payment by the Company on such Senior Indebtedness. 
  
 
SECTION 11.07. Relative Rights. This Article 11 defines the relative rights of Securityholders and holders of Senior Indebtedness of the Company. Nothing in this Indenture shall: 
  
 (1) impair, as between the Company and Securityholders, the
obligation of the Company, which is absolute and unconditional, to pay principal of and interest on the Securities in accordance with their terms; or 
  
 (2) prevent the Trustee or any Securityholder from exercising its available remedies upon a Default, subject to the rights of holders of
Senior Indebtedness of the Company to receive distributions otherwise payable to Securityholders. 
  
 
SECTION 11.08. Subordination May Not Be Impaired by Company. No right of any holder of Senior Indebtedness of the Company to enforce the subordination of the Indebtedness evidenced by the Securities shall be
impaired by any act or failure to act by the Company or by its failure to comply with this Indenture. 
  
 
SECTION 11.09. Rights of Trustee and Paying Agent. Notwithstanding Section 11.03, the Trustee or Paying Agent may continue to make payments on the Securities and shall not be charged with knowledge of the
existence of facts that would prohibit the making of any such payments unless, not less than two Business Days prior to the date of such payment, a Trust Officer of the Trustee receives notice satisfactory to it that payments may not be made under
this Article 11. The Company, the Registrar or co-registrar, the Paying Agent, a Representative or a holder of Senior Indebtedness may give the notice. 
  
 The Trustee in its individual or any other capacity may hold Senior Indebtedness of the Company with the same rights it would have if it were not Trustee.
The Registrar and co-registrar and the Paying Agent may do the same with like rights. The Trustee shall be entitled to all the rights set forth in this Article 11 with respect to any Senior Indebtedness of the Company which may at any time be held
by it, to the same extent as any other holder of such Senior Indebtedness; and nothing in Article 8 shall deprive the Trustee of any of its rights as such holder. Nothing in this Article 11 shall apply to claims of, or payments to, the Trustee under
or pursuant to Section 8.07. 
  
 
SECTION 11.10. Distribution or Notice to Representative. Whenever a distribution is to be made or a notice given to holders of Senior Indebtedness of the Company, the distribution may be made and the notice given
to their Representative (if any). 
  
 
SECTION 11.11. Article 11 Not To Prevent Events of Default or Limit Right To Accelerate. The failure to make a payment pursuant to the Securities by reason of any provision in this Article 11 shall not be
construed as preventing the occurrence of a Default. Nothing in this Article 11 shall have any effect on the right of the Securityholders or the Trustee to accelerate the maturity of the Securities.

SECTION 11.12. Trustee Entitled To Rely. Upon any payment or distribution pursuant to this Article 11, the Trustee and the Securityholders shall be entitled to rely (i) upon any order or decree of a court of
competent jurisdiction in which any proceedings of the nature referred to in Section 11.02 are pending, (ii) upon a certificate of the liquidating trustee or agent or other Person making such payment or distribution to the Trustee or to the
Securityholders or (iii) upon the Representatives for the holders of Senior Indebtedness of the Company for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, the holders of such Senior Indebtedness and
other Indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article 11. In the event that the Trustee determines, in good faith, that
evidence is required with respect to the right of any Person as a holder of Senior Indebtedness of the Company to participate in any payment or distribution pursuant to this Article 11, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of such Senior Indebtedness held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and other facts pertinent to the rights of such
Person under this Article 11, and, if such evidence is not furnished, the Trustee may defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment. The provisions of Sections 8.01 and 8.02
shall be applicable to all actions or omissions of actions by the Trustee pursuant to this Article 11. 
  
 
SECTION 11.13. Trustee To Effectuate Subordination. Each Securityholder by accepting a Security authorizes and directs the Trustee on its behalf to take such action as may be necessary or appropriate to
acknowledge or effectuate the subordination between the Securityholders and the holders of Senior Indebtedness of the Company as provided in this Article 11 and appoints the Trustee as attorney-in-fact for any and all such purposes. 
  
 
SECTION 11.14. Trustee Not Fiduciary for Holders of Senior Indebtedness. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness and shall not be liable to any such holders
if it shall mistakenly pay over or distribute to Securityholders or the Company or any other Person, money or assets to which any holders of Senior Indebtedness of the Company shall be entitled by virtue of this Article 11 or otherwise. 

 
 
SECTION 11.15. Reliance by Holders of Senior Indebtedness on Subordination Provisions. Each Securityholder by accepting a Security acknowledges and agrees that the foregoing subordination provisions are, and are
intended to be, an inducement and a consideration to each holder of any Senior Indebtedness of the Company, whether such Senior Indebtedness was created or acquired before or after the issuance of the Securities, to acquire and continue to hold, or
to continue to hold, such Senior Indebtedness and such holder of such Senior Indebtedness shall be deemed conclusively to have relied on such subordination provisions in acquiring and continuing to hold, or in continuing to hold, such Senior
Indebtedness.

provided, however, that such interest may be increased by any Additional Interest accruing from time to time on the principal amount of this Security as provided in the Registration Rights Agreement. Any reference herein to interest
accrued or payable as of any date shall include any Additional Interest accrued or payable on such date as provided in the Registration Rights Agreement. Interest on the Securities shall accrue from the most recent date to which interest has been
paid or, if no interest has been paid, from May 28, 2003; provided, however, that if there is not an existing Default in the payment of interest and if this Security is authenticated between a record date referred to on the face hereof
and the next succeeding interest payment date, interest shall accrue from such interest payment date. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 
  
 2.    Method of Payment 
  

The Company shall pay interest on this Security (except defaulted interest) to the person who is the Holder of this Security at the close of business
on May 15 or November 15, as the case may be, next preceding the related interest payment date. The Holder must surrender this Security to a Paying Agent to collect payment of principal. The Company will pay principal and interest in money of the
United States that at the time of payment is legal tender for payment of public and private debts. The Company may, however, pay principal and interest in respect of any Certificated Security by check or wire payable in such money; provided,
however, that a Holder with an aggregate principal amount in excess of $2,000,000 will be paid by wire transfer in immediately available funds at the election of such Holder. The Company may mail an interest check to the Holder’s
registered address. Notwithstanding the foregoing, so long as this Security is registered in the name of a Depositary or its nominee, all payments hereon shall be made by wire transfer of immediately available funds to the account of the Depositary
or its nominee. 
  
 3.    Paying Agent, Registrar and
Conversion Agent 
  
 Initially, U.S. Bank National Association
(the “Trustee”, which term shall include any successor trustee under the Indenture hereinafter referred to) will act as Paying Agent, Registrar and Conversion Agent. The Company may change any Paying Agent, Registrar or
Conversion Agent without notice to the Holder. The Company or any

of its Subsidiaries may, subject to certain limitations set forth in the Indenture, act as Paying Agent or Registrar. 
  
 4.    Indenture, Limitations 
  
 This Security is one of a duly authorized issue of Securities of the Company
designated as its 2.50% Convertible Subordinated Notes Due 2008 (the “Securities”) issued under an Indenture dated as of May 28, 2003 (together with any supplemental indentures thereto, the
“Indenture”), among ChipPAC, Inc. (the “Company”), and the Trustee. Capitalized terms herein are used as defined in the Indenture unless otherwise defined herein. The terms of this Security include
those stated in the Indenture and those required by or made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended, as in effect on the date of the Indenture. This Security is subject to all such terms, and the Holder of
this Security is referred to the Indenture and said Act for a statement of them. The Securities are subordinated unsecured obligations of the Company limited to $150,000,000 aggregate principal amount. The Indenture does not limit other debt
of the Company, secured or unsecured, including Senior Indebtedness. 
  
 5.    Purchase of Securities at Option of Holder Upon a Change of Control 
  
 At the option of the Holder and subject to the terms and conditions of the Indenture, the Company shall become obligated to purchase all or any part
specified by the Holder (so long as the principal amount of such part is $1,000 or an integral multiple of $1,000 in excess thereof) of the Securities held by such Holder on the date that is no less than 30 days and not more than 60 days after
notice of the occurrence of a Change of Control is given as provided in Section 4.07, at a purchase price equal to 100% of the principal amount thereof together with accrued interest up to, but excluding, the Change of Control Purchase Date. The
Holder shall have the right to withdraw any Change of Control Purchase Notice (in whole or in a portion thereof that is $1,000 or an integral multiple of $1,000 in excess thereof) at any time prior to the close of business on the Business Day next
preceding the Change of Control Purchase Date by delivering a written notice of withdrawal to the Paying Agent in accordance with the terms of the Indenture. 
  
 6.    Conversion 
  
 A Holder of a Security may convert the principal amount of such Security (or any portion thereof equal to $1,000 or any integral multiple of $1,000 in
excess thereof) into shares of Common Stock at any time prior to the close of business on the Business Day immediately preceding June 1, 2008; provided, however, that if the Security is subject to purchase upon a Change of Control, the
conversion right will terminate at the close of business on the Business Day immediately preceding the Change of Control Purchase Date for such Security or such earlier date as the Holder presents such Security for purchase (unless the Company shall
default in making the Change of Control Purchase Price when due, in which case the conversion right shall terminate at the close of business on the date such default is cured and such Security is purchased). 







Table of Contents



 9 
  

 
The initial Conversion Price is $8.062 per share, subject to adjustment under certain circumstances. The number of shares of Common Stock issuable upon
conversion of a Security is determined by dividing the principal amount of the Security or portion thereof converted by the Conversion Price in effect on the Conversion Date. No fractional shares will be issued upon conversion; in lieu thereof, an
amount will be paid in cash based upon the Closing Price (as defined in the Indenture) of the Common Stock on the Trading Day immediately prior to the Conversion Date. To convert a Security, a Holder must (a) complete and manually sign the
conversion notice set forth below and deliver such notice to a Conversion Agent, (b) surrender the Security to a Conversion Agent, (c) furnish appropriate endorsements and transfer documents if required by a Registrar or a Conversion Agent, and (d)
pay any transfer or similar tax, if required. Securities so surrendered for conversion (in whole or in part) 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 (excluding Securities or portions thereof which are subject to purchase following a Change of Control on a date during the period beginning at the close of business on a regular record date and ending at the opening of business on the first
Business Day after the next succeeding interest payment date, or if such interest payment date is not a Business Day, the second such Business Day) shall also be accompanied by payment in funds acceptable to the Company of an amount equal to the
interest payable on such interest payment date on the principal amount of such Security then being converted, and such interest shall be payable to such registered Holder notwithstanding the conversion of such Security, subject to the provisions of
this Indenture relating to the payment of defaulted interest by the Company. If the Company defaults in the payment of interest payable on such interest payment date, the Company shall promptly repay such funds to such Holder. A Holder may convert a
portion of a Security equal to $1,000 or any integral multiple thereof. A Security in respect of which a Holder had delivered a Change of Control Purchase Notice exercising the option of such Holder to require the Company to purchase such Security
may be converted only if the Change of Control Purchase Notice is withdrawn in accordance with the terms of the Indenture. 
  
 7.    Subordination 
  
 The indebtedness evidenced by the Securities is, to the extent and in the manner provided in the Indenture, subordinate and junior in right of payment to
the prior payment in full of all Senior Indebtedness of the Company. Any Holder by accepting this Security agrees to and shall be bound by such subordination provisions and authorizes the Trustee to give them effect. In addition to all other rights
of Senior Indebtedness described in the Indenture, the Senior Indebtedness shall continue to be Senior Indebtedness and entitled to the benefits of the subordination provisions irrespective of any amendment, modification or waiver of any terms of
any instrument relating to the Senior Indebtedness or any extension or renewal of the Senior Indebtedness. 
  
 8.    Denominations, Transfer, Exchange 
  
 The Securities are in registered form without coupons in denominations of $1,000 and integral multiples of $1,000. A Holder may register the transfer of
or

exchange Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and
transfer documents and to pay any taxes or other governmental charges that may be imposed in relation thereto by law or permitted by the Indenture. 
  
 9.    Persons Deemed Owners 
  
 The Holder of a Security may be treated as the owner of it for all purposes. 
  
 10.    Unclaimed Money 
  

If money for the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent will pay the money back to the Company
at its written request. After that, Holders entitled to money must look to the Company for payment. 
  
 11.    Amendment, Supplement and Waiver 
  
 Subject to certain exceptions, the Indenture or the Securities may be amended or supplemented with the consent of the Holders of at least a majority in
principal amount of the Securities then outstanding, and an existing Default or Event of Default and its consequence or compliance with any provision of the Indenture or the Securities may be waived in a particular instance with the consent of the
Holders of a majority in principal amount of the Securities then outstanding. Without the consent of or notice to any Holder, the Company and the Trustee may amend or supplement the Indenture or the Securities to, among other things, cure any
ambiguity, defect or inconsistency or make any other change that does not adversely affect the rights of any Holder. 
  
 12.    Successor Corporation 
  
 When a successor corporation assumes all the obligations of its predecessor under the Securities and the Indenture in accordance with the terms and
conditions of the Indenture, the predecessor corporation will (except in certain circumstances specified in the Indenture) be released from those obligations. 
  

13.    Defaults and Remedies 
  
 Under the Indenture, an Event of Default includes: 
 (1) the
Company defaults in any payment of interest on any Security when the same becomes due and payable, whether or not such payment shall be prohibited by Article 11, and such default continues for a period of 30 days; (2) the Company (i) defaults in the
payment of the principal of any Security when the same becomes due and payable at its Stated Maturity, upon declaration of acceleration or otherwise, whether or not such payment shall be prohibited by Article 11 or (ii) fails to purchase Securities
when required pursuant to this Indenture or the Securities, whether or not such purchase shall be prohibited by Article 11; (3) the Company fails to comply with its obligations with respect to a Change of Control in accordance with Sections 4.07,
4.08, 4.09, 4.10 and 







Table of Contents



 11 
  

 
4.11 (other than its obligation to purchase securities properly submitted for purchase); (4) the Company fails to comply with its obligations under Section
6.01; (5) the Company fails to comply with any of its agreements in the Securities or the Indenture (other than those referred to in clauses (1) through (4) above) and such failure continues for 60 days after the notice specified below; or (6) the
Company pursuant to or within the meaning of any Bankruptcy Law: (A) commences a voluntary case; (B) consents to the entry of an order for relief against it in an involuntary case; (C) consents to the appointment of a Custodian of it or for a
substantial part of its property; or (D) makes a general assignment for the benefit of its creditors; (7) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: (A) is for relief against the Company in an
involuntary case; (B) appoints a Custodian of the Company or for all or substantially all of its property; or (C) orders the winding up or liquidation of the Company; and the order or decree remains unstayed and in effect for 60 days (together with
Clause (6), the “bankruptcy provisions”); (8) Indebtedness of the Company is not paid within 15 days of any applicable grace period after final maturity or is accelerated by the holders thereof because of a default and the total amount of
such Indebtedness unpaid or accelerated exceeds $15.0 million (the “cross acceleration provision”). 
  
 If an Event of Default (other than an event of default as described in clauses (6) and (7) with respect to the Company) occurs and is continuing, the
Trustee or the Holders of at least 25% in principal amount of the Securities then outstanding may declare all unpaid principal to the date of acceleration on the Securities then outstanding to be due and payable immediately, all as and to the extent
provided in the Indenture. If an Event of Default occurs as a result of certain events of bankruptcy, insolvency or reorganization of the Company or as described in clauses (6) and (7) herein, unpaid principal of the Securities then outstanding
shall become due and payable immediately without any declaration or other act on the part of the Trustee or any Holder, all as and to the extent provided in the Indenture. Holders may not enforce the Indenture or the Securities except as provided in
the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in principal amount of the Securities then outstanding may direct the
Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing Default (except a Default in payment of principal or interest) if it determines that withholding notice is in their interests. The Company
is required to file periodic reports with the Trustee as to the absence of Default. 
  
 14.    Trustee Dealings with the Company 
  
 U.S. Bank National Association, the Trustee under the Indenture, in its individual or any other capacity, may make loans to, accept deposits from and perform services for the Company or an Affiliate of the Company,
and may otherwise deal with the Company or an Affiliate of the Company, as if it were not the Trustee. 
  
 15.    No Recourse Against Others 
  
 A director, officer, employee or shareholder, as such, of the Company shall not have any liability for any obligations of the Company under the Securities or the 







Table of Contents



 12 
  

 
Indenture nor for any claim based on, in respect of or by reason of such obligations or their creation. The Holder of this Security by accepting this
Security waives and releases all such liability. The waiver and release are part of the consideration for the issuance of this Security. 
  
 16.    Authentication 
  
 This Security shall not be valid until the Trustee or an authenticating agent manually signs the certificate of authentication on the other side of this
Security. 
  
 17.    Abbreviations and Definitions

  
 Customary abbreviations may be used in the name of the 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 UGMA (= Uniform Gifts to Minors Act). All terms
defined in the Indenture and used in this Security but not specifically defined herein are defined in the Indenture and are used herein as so defined. 
  
 18.    Indenture to Control; Governing Law 
  
 In the case of any conflict between the provisions of this Security and the Indenture, the provisions of the Indenture shall control. This Security shall
be governed by, and construed in accordance with, the laws of the State of New York, without regard to principles of conflicts of law.
