authentication shall be substantially in the respective forms set forth in Exhibit A, which Exhibit is incorporated in and made part of this Indenture. The Securities may have notations, legends or endorsements 

  

 - 8 - 








 
required by law, stock exchange rule or usage. The Company shall provide any such notations, legends or endorsements to the Trustee in writing. Each Security
shall be dated the date of its authentication. The Securities are being offered and sold by the Company pursuant to a Purchase Agreement dated November __, 2005 (the “Purchase Agreement”) between the Company and the Purchasers
thereunder, in transactions exempt from, or not subject to, the registration requirements of the Securities Act. 
  
 (a) Restricted Global Securities. All of the Securities are initially being offered and sold to qualified institutional buyers as defined
in Rule 144A (collectively, “QIBs” or individually, each a “QIB”) 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,” and such depositary, or any successor thereto, being hereinafter referred to as
the “Depositary”), and registered in the name of its nominee, Cede & Co., duly executed by the Company and authenticated by the Trustee as hereinafter provided. The aggregate principal amount of the Restricted Global
Securities may from time to time be increased or decreased by adjustments made on the records of the Trustee, as custodian with respect to the Securities in global form, as hereinafter provided, subject in each case to compliance with the Applicable
Procedures. 
  
 (b) Global Securities In General.

aggregate amount of outstanding Securities represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges, redemptions, repurchases or conversions of such Securities. Any adjustment of the aggregate principal
amount of a Global Security to reflect the amount of any increase or decrease in the amount of outstanding Securities represented thereby shall be made by the Trustee in accordance with instructions given by the Holder thereof as required by
Section 2.12 hereof and shall be made on the records of the Trustee and the Depositary. 
  
 Members of, or participants in, the Depositary (“Agent Members”) shall have no rights under this Indenture with respect to any Global Security held on their behalf by the Depositary or under the
Global Security, and the Depositary (including, for this purpose, its nominee) may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and Holder of such Global Security for all purposes
whatsoever. Notwithstanding the foregoing, nothing herein shall (1) prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the
Depositary or (2) impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a Holder of any Security. 
  

 - 9 - 








 (c) Book Entry Provisions. The Company shall execute and the Trustee shall, in accordance
with this Subsection 2.1(c) and Section 2.2, authenticate and deliver initially one or more Global Securities that (1) shall be registered in the name of Cede & Co. or as otherwise instructed by the Depositary, (2) shall be
delivered by the Trustee to the Depositary or pursuant to the Depositary’s instructions and (3) shall bear legends substantially to the following effect: 
  
 “UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY TO i2
TECHNOLOGIES, INC. (THE “COMPANY”) OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED
REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY (AND ANY PAYMENT HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF
FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN. THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED
IN THE NAME OF A DEPOSITARY OR A NOMINEE THEREOF. THIS SECURITY IS EXCHANGEABLE FOR SECURITIES REGISTERED IN THE NAME OF A PERSON OTHER THAN THE DEPOSITARY OR ITS NOMINEE ONLY IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE AND, UNLESS AND
UNTIL IT IS EXCHANGED IN WHOLE OR IN PART FOR SECURITIES IN DEFINITIVE FORM, THIS SECURITY MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITARY TO A NOMINEE OF THE DEPOSITARY OR BY A NOMINEE OF THE DEPOSITARY TO THE DEPOSITARY OR ANOTHER
NOMINEE OF THE DEPOSITARY OR BY THE DEPOSITARY OR ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITARY OR A NOMINEE OF SUCH SUCCESSOR DEPOSITARY.” 
  
 Section 2.2. Execution and Authentication. 
  
 (a) The aggregate principal amount of Securities which may be authenticated and delivered under this Indenture is limited to $75,000,000
(subject to increase by up to an additional aggregate principal amount of $11,250,000 in the event the Purchasers (as defined in the Purchase Agreement) exercise the right to purchase Additional Securities (as defined in the Purchase Agreement)
pursuant to the Purchase Agreement) except as provided in Sections 2.6 and 2.7. 
  
 (b) An Officer shall sign the Securities for the Company by manual or facsimile signature attested by the manual or facsimile signature of
the Secretary or an Assistant Secretary of the Company. Typographic and other minor errors or defects in any such facsimile signature shall not affect the validity or enforceability of any Security which has been authenticated and delivered by the
Trustee. 
  
 (c) If an Officer whose signature is
on a Security no longer holds that office at the time the Trustee authenticates the Security, the Security shall be valid nevertheless. 
  

 - 10 - 








 (d) 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. 
  
 (e) The Trustee shall authenticate and make available for delivery Securities for original issue upon
receipt of a written order or orders of the Company signed by two Officers of the Company (a “Company Order”). Subject to Section 2.2(a), the Company Order shall specify the amount of Securities to be authenticated, shall
provide that all such Securities will be represented by a Restricted Global Security and the date on which each original issue of Securities is to be authenticated. 
  
 (f) The Trustee shall act as the initial authenticating agent. Thereafter, the Trustee may appoint an
authenticating agent acceptable to the Company to authenticate Securities. An authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication
by such agent. An authenticating agent shall have the same rights as an Agent to deal with the Company or an Affiliate of the Company. 
  
 (g) The Securities shall be issuable only in registered form without coupons and only in denominations of $1,000 principal amount and any
integral multiple thereof. 
  
 Section 2.3. Registrar, Paying
Agent and Conversion Agent. 
  
 (a) The
Company shall maintain one or more offices or agencies where Securities may be presented for registration of transfer or for exchange (each, a “Registrar”), one or more offices or agencies where Securities may be presented for
payment (each, a “Paying Agent”), one or more offices or agencies where Securities may be presented for conversion (each, a “Conversion Agent”) and one or more offices or agencies where notices and demands to or
upon the Company in respect of the Securities and this Indenture may be served. The Company shall at all times maintain a Registrar, Paying Agent, Conversion Agent and an office or agency where notices and demands to or upon the Company in respect
of the Securities and this Indenture may be served in the Borough of Manhattan, The City of New York. One of the Registrars (the “Primary Registrar”) shall keep a register of the Securities and of their transfer and exchange.

  
 (b) The Company shall enter into an
appropriate agency agreement with any Agent not a party to this Indenture. 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 Agent not a
party to this Indenture. If the Company fails to maintain a Registrar, Paying Agent, Conversion Agent or agent for service of notices and demands in any place required by this Indenture, or fails to give the foregoing notice, the Trustee shall act
as such. The Company or any Affiliate of the Company may act as Paying Agent (except for the purposes of Section 6.1 and Article 10). 
  
 (c) The Company hereby initially designates the Trustee as Registrar, Paying Agent and Conversion Agent, and each of the Corporate Trust
Office of the Trustee and the office or agency of the Trustee in the Borough of Manhattan, The City of New York (which shall 

  

 - 11 - 








 
initially be JPMorgan Chase Bank, N.A., Worldwide Securities Services, 4 New York Plaza, New York, N.Y. 10004) to be such office or agency of the Company for
each of the aforesaid purposes. 
  
 Section 2.4. Paying Agent
to Hold Money in Trust. 
  
 Prior to 11:00 a.m., New York
City time, on each due date of the principal of, or interest on, any Securities, the Company shall deposit or cause to be deposited with a Paying Agent a sum sufficient to pay such principal or interest so becoming due. Subject to Section 10.2,
a 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 shall notify the Trustee of any default by the Company (or
any other obligor on the Securities) in making any such payment. If the Company or an Affiliate of the Company acts as Paying Agent, it shall, before 11:00 a.m., New York City time, on each due date of the principal of, or interest on, any
Securities, segregate the money 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 the Trustee may at any time during the continuance of any default, upon written
request to a Paying Agent, require such Paying Agent to pay forthwith to the Trustee all sums so held in trust by such Paying Agent. Upon doing so, the Paying Agent (other than the Company) shall have no further liability for the money. 

 
 Section 2.5. 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 Primary Registrar, the Company shall furnish to the Trustee on or before each semiannual 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 2.6. Transfer and Exchange. 
  
 (a) Subject to compliance with any applicable additional requirements contained in Section 2.12, when a Security is presented to a
Registrar with a request to register a transfer thereof or to exchange such Security for an equal principal amount of Securities of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested;
provided, however, that every Security presented or surrendered for registration of transfer or exchange 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 form satisfactory to the Registrar, duly executed by the Holder thereof or its attorney duly authorized in writing. To permit registration of transfers and exchanges, upon surrender of any Security for transfer or exchange at an
office or agency maintained pursuant to Section 2.3, the Company shall execute and the Trustee shall authenticate Securities of a like aggregate principal amount at the Registrar’s request. Any exchange or transfer shall be without charge,
except that the Company or the Registrar may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto; provided, that this sentence shall not apply to any exchange pursuant to
Section 2.10, 2.12(a), 3.6, 3.13, or 11.5. 
  

 - 12 - 








 (b) None of the Company, any Registrar or the Trustee shall be required to exchange or
register a transfer of (1) any Securities for a period of 15 days next preceding mailing of a notice of Securities to be redeemed, (2) any Securities or portions thereof selected or called for redemption (except in the case of redemption
of a Security in part, the portion thereof not to be redeemed) or (3) any Securities or portions thereof in respect of which a Repurchase Notice, Preferred Redemption Repurchase Notice or Fundamental Change Repurchase Notice has been delivered
and not withdrawn by the Holder thereof (except, in the case of the repurchase of a Security in part, the portion thereof not to be repurchased). 
  
 (c) All Securities issued upon any transfer or exchange of Securities shall be valid obligations of the Company, evidencing the same debt
and entitled to the same benefits under this Indenture, as the Securities surrendered upon such transfer or exchange. 
  
 (d) Any Registrar appointed pursuant to Section 2.3 hereof shall provide to the Trustee such information as the Trustee may
reasonably require in connection with the delivery by such Registrar of Securities upon transfer or exchange of Securities. 
  
 (e) Each Holder of a Security agrees to indemnify the Company and the Trustee against any liability that may result from the transfer,
exchange or assignment of such Holder’s Security in violation of any provision of this Indenture and/or applicable United States federal or state securities law. 
  
 (f) 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 Agent Members or other beneficial owners of interests 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 2.7. Replacement Securities. 
  
 (a) If any mutilated Security is surrendered to the Company, a Registrar or the Trustee, or the Company, a Registrar and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Security, and there is
delivered to the Company, the applicable Registrar and the Trustee such security or indemnity as will be required by them to save each of them harmless, then, in the absence of notice to the Company, such Registrar or the Trustee that such Security
has been acquired by a bona fide purchaser, the Company shall execute, and upon its written request the Trustee shall authenticate and deliver, in exchange for any such mutilated Security or in lieu of any such destroyed, lost or stolen Security, a
new Security of like tenor and principal amount, bearing a number not contemporaneously outstanding. 
  
 (b) In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, or is about to be
redeemed or repurchased by the Company pursuant to Article 3, the Company in its discretion may, instead of issuing a new Security, pay, redeem or repurchase such Security, as the case may be. 
  

 - 13 - 








 (c) Upon the issuance of any new Securities under this Section 2.7, the Company may
require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other reasonable expenses (including the reasonable fees and expenses of the Trustee or the Registrar) in
connection therewith. 
  
 (d) Every new Security
issued pursuant to this Section 2.7 in lieu of any mutilated, destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the mutilated, destroyed, lost or stolen Security
shall be at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and proportionately with any and all other Securities duly issued hereunder. 
  
 (e) The provisions of this Section 2.7 are (to the extent lawful) exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities. 
  
 Section 2.8. Outstanding Securities. 
  
 (a) Securities outstanding at any time are all Securities authenticated by the Trustee, except for those canceled by it, those redeemed or
repurchased pursuant to Article 3, those converted pursuant to Article 4, those delivered to the Trustee for cancellation or surrendered for transfer or exchange and those described in this Section 2.8 as not outstanding. 
  
 (b) If a Security is replaced pursuant to Section 2.7,
it ceases to be outstanding unless the Company receives proof satisfactory to it that the replaced Security is held by a bona fide purchaser. 
  
 (c) If a Paying Agent (other than the Company or an Affiliate of the Company) holds in respect of the outstanding Securities on a
Redemption Date, a Repurchase Date, a Preferred Redemption Repurchase Date, a Fundamental Change Repurchase Date or the Final Maturity Date money sufficient to pay the principal of (including premium, if any) and accrued interest on Securities (or
portions thereof) payable on that date, then on and after such Redemption Date, Repurchase Date, Preferred Redemption Repurchase Date, Fundamental Change Repurchase Date or Final Maturity Date, as the case may be, such Securities (or portions
thereof, as the case may be) shall cease to be outstanding and interest on them shall cease to accrue; provided, that if such Securities are to be redeemed, notice of such redemption has been duly given pursuant to this Indenture or provision
thereof satisfactory to the Trustee has been made. 
  
 (d) Subject to the restrictions contained in Section 2.9, a Security does not cease to be outstanding because the Company or an Affiliate of the Company holds the Security. 
  
 Section 2.9. Treasury Securities. 
  
 In determining whether the Holders of the required principal amount of Securities have concurred in any notice, direction,
waiver or consent, Securities owned by the Company or any other obligor on the Securities or by any Affiliate of the Company or of such other obligor shall be disregarded, except that, for purposes of determining whether the Trustee shall be
protected in relying on any such notice, direction, waiver or consent, only Securities which a Trust Officer of 

  

 - 14 - 








 
the Trustee actually knows are so owned shall be so disregarded. Securities so owned which have been pledged in good faith shall not be disregarded if the
pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to act with respect to the Securities and that the pledgee is not the Company or any other obligor on the Securities or any Affiliate of the Company or of such other
obligor. 
  
 Section 2.10. Temporary Securities.

  
 Until definitive Securities are ready for delivery, the
Company may prepare and execute, and, upon receipt of a Company Order, the Trustee shall authenticate and deliver, temporary Securities. Temporary Securities shall be substantially in the form of definitive Securities but may have variations that
the Company with the consent of the Trustee considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate and deliver definitive Securities in exchange for temporary
Securities. 
  
 Section 2.11. 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 or its agent any Securities surrendered to them for transfer, exchange, redemption, repurchase, payment or conversion. The Trustee and no one else
shall cancel, in accordance with its standard procedures, all Securities surrendered for transfer, exchange, redemption, repurchase, payment, conversion or cancellation and shall deliver the canceled Securities to the Company. All Securities which
are redeemed, repurchased or otherwise acquired by the Company or any of its Subsidiaries prior to the Final Maturity Date shall be delivered to the Trustee for cancellation, and the Company may not hold or resell such Securities or issue any new
Securities to replace any such Securities or any Securities that any Holder has converted pursuant to Article 4. 
  
 Section 2.12. Legend; Additional Transfer and Exchange Requirements. 
  
 (a) If Securities are issued upon the transfer, exchange or replacement of Securities subject to
restrictions on transfer and bearing the legends set forth on the forms of Securities attached hereto as Exhibit A (collectively, the “Legend”), or if a request is made to remove the Legend on a Security, the Securities so issued
shall bear the Legend, or the Legend shall not be removed, as the case may be, unless there is delivered to the Company and the Registrar such satisfactory evidence, which shall include an opinion of counsel if requested by the Company or such
Registrar, as may be reasonably required by the Company and the Registrar, that neither the Legend nor the restrictions on transfer set forth therein are required to ensure that transfers thereof comply with the provisions of Rule 144A, Rule 144 or
Regulation S under the Securities Act or that such Securities are not “restricted” within the meaning of Rule 144 under the Securities Act; provided, that no such evidence need be supplied in connection with the sale of such Security
pursuant to a registration statement that is effective at the time of such sale. Upon (1) provision of such satisfactory evidence if requested, or (2) notification by the Company to the Trustee and Registrar of the sale of such Security
pursuant to a registration statement that is effective at the time of such sale, the Trustee, at the written direction of the Company, shall authenticate and deliver a Security that does not bear the Legend. If the Legend 

  

 - 15 - 








 
is removed from the face of a Security and the Security is subsequently held by an Affiliate of the Company, the Legend shall be reinstated. 
  
 (b) A Global Security may not be transferred, in whole or in
part, to any Person other than the Depositary or a nominee or any successor thereof, and no such transfer to any such other Person may be registered; provided, that the foregoing shall not prohibit any transfer of a Security that is issued in
exchange for a Global Security but is not itself a Global Security. No transfer of a Security to any Person shall be effective under this Indenture or the Securities unless and until such Security has been registered in the name of such Person.
Notwithstanding any other provisions of this Indenture or the Securities, transfers of a Global Security, in whole or in part, shall be made only in accordance with this Section 2.12. 
  
 (c) Subject to the succeeding paragraph, every Security
shall be subject to the restrictions on transfer provided in the Legend other than a Restricted Global Security. Whenever any Restricted Security other than a Restricted Global Security is presented or surrendered for registration of transfer or for
exchange for a Security registered in a name other than that of the Holder, such Security must be accompanied by a certificate in substantially the form set forth in Exhibit A, dated the date of such surrender and signed by the Holder of such
Security, as to compliance with such restrictions on transfer. The Registrar shall not be required to accept for such registration of transfer or exchange any Security not so accompanied by a properly completed certificate. 
  
 (d) The restrictions imposed by the Legend upon the
transferability of any Security shall cease and terminate when such Security has been sold pursuant to an effective registration statement under the Securities Act or transferred in compliance with Rule 144 under the Securities Act (or any successor
provision thereto) or, if earlier, upon the expiration of the holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any successor provision). Any Security as to which such restrictions on transfer shall have
expired in accordance with their terms or shall have terminated may, upon a surrender of such Security for exchange to the Registrar in accordance with the provisions of this Section 2.12 (accompanied, in the event that such restrictions on
transfer have terminated by reason of a transfer in compliance with Rule 144 or any successor provision, by, if requested by the Company or the Registrar, an opinion of counsel reasonably acceptable to the Company and addressed to the Company in
form acceptable to the Company, to the effect that the transfer of such Security has been made in compliance with Rule 144 or such successor provision), be exchanged for a new Security, of like tenor and aggregate principal amount, which shall not
bear the restrictive Legend. The Company shall inform the Trustee of the effective date of any registration statement registering the Securities under the Securities Act. The Trustee shall not be liable for any action taken or omitted to be taken by
it in good faith in accordance with the aforementioned opinion of counsel or registration statement. 
  
 As used in the preceding Subsections 2.12(c) and (d), the term “transfer” encompasses any sale, pledge, transfer, hypothecation or other
disposition of any Security.

 (e) The provisions below shall apply only to Global Securities: 
  
 (1) Notwithstanding any other provisions of this Indenture
or the Securities, a Global Security shall not be exchanged in whole or in part for a Security registered in the name of any Person other than the Depositary or one or more nominees thereof, provided that a Global Security may be exchanged for
Securities registered in the names of any person designated by the Depositary in the event that (A) the Depositary has notified the Company that it is unwilling or unable to continue as Depositary for such Global Security or such Depositary has
ceased to be a “clearing agency” registered under the Exchange Act, and a successor Depositary is not appointed by the Company within 90 days, (B) the Company has provided the Depositary with written notice that it has decided to
discontinue use of the system of book-entry transfer through the Depositary or any successor Depositary or (C) an Event of Default has occurred and is continuing with respect to the Securities. Any Global Security exchanged pursuant to
subclauses (A) or (B) immediately above shall be so exchanged in whole and not in part, and any Global Security exchanged pursuant to subclause (C) immediately above may be exchanged in whole or from time to time in part as directed
by the Depositary. Any Security issued in exchange for a Global Security or any portion thereof shall be a Global Security; provided, that any such Security so issued that is registered in the name of a Person other than the Depositary or a
nominee thereof shall not be a Global Security. 
  
 (2) Securities issued in exchange for a Global Security or any portion thereof shall be issued in definitive, fully registered form, without interest coupons, shall have an aggregate principal amount equal to that of such Global Security or
portion thereof to be so exchanged, shall be registered in such names and be in such authorized denominations as the Depositary shall designate and shall bear the applicable legends provided for herein. Any Global Security to be exchanged in whole
shall be surrendered by the Depositary to the Trustee, as Registrar. With regard to any Global Security to be exchanged in part, either such Global Security shall be so surrendered for exchange or, if the Trustee is acting as custodian for the
Depositary or its nominee with respect to such Global Security, the principal amount thereof shall be reduced, by an amount equal to the portion thereof to be so exchanged, by means of an appropriate adjustment made on the records of the Trustee, as
Registrar. Upon any such surrender or adjustment, the Trustee shall authenticate and deliver the Security issuable on such exchange to or upon the order of the Depositary or an authorized representative thereof. 
  
 (3) Subject to the provisions of clause (5) of this
Subsection 2.12(e), the registered Holder may grant proxies and otherwise authorize any Person, including Agent Members and persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this
Indenture or the Securities. 
  
 (4) In the event
of the occurrence of any of the events specified in clause (1) of this Subsection 2.12(e) above, the Company will promptly make available to the Trustee a reasonable supply of Certificated Securities in definitive, fully registered form,
without interest coupons. 
  
 (5) Neither Agent
Members nor any other Persons on whose behalf Agent Members may act shall have any rights under this Indenture with respect to any Global Security registered in the name of the Depositary or any nominee thereof, or 

  

 - 17 - 








 
under any such Global Security, and the Depositary or such nominee, as the case may be, may be treated by the Company, the Trustee and any agent of the
Company or the Trustee as the absolute owner and holder of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving
effect to any written certification, proxy or other authorization furnished by the Depositary or such nominee, as the case may be, or impair, as between the Depositary, its Agent Members and any other Person on whose behalf an Agent Member may act,
the operation of customary practices of such Persons governing the exercise of the rights of a holder of any Security. 
  
 Section 2.13. CUSIP Numbers. 
  
 The Company in issuing the Securities may use one or more “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use
“CUSIP” numbers in notices of redemption or repurchase as a convenience to Holders; provided, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or
as contained in any notice of a redemption or repurchase and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption or repurchase 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 2.14. Rank. 
  
 The Securities shall constitute senior indebtedness of the Company and shall rank pari passu with all other senior indebtedness of the Company and senior
to all other indebtedness of the Company.

stock” means any class or classes of Capital Stock pursuant to which the holders of Capital Stock under ordinary circumstances have the power to vote in the election of the board of directors, managers or trustees of any person or other
persons performing similar functions irrespective of whether or not, at the time, Capital Stock of any other class or classes shall have, or might have, voting power by reason of the happening of any contingency. 
  
 Notwithstanding anything in this Indenture to the contrary, a merger or
consolidation shall not be deemed to constitute a “Change in Control” if at least 90% of the consideration (excluding cash payments for fractional shares and cash payments pursuant to dissenters’ appraisal rights) in the merger or
consolidation consists of shares of Capital Stock or American Depositary Shares that are (A) listed on, or immediately after the transaction will be listed on, the New York Stock Exchange or (B) approved, or immediately after the
transaction will be approved, for quotation on the Nasdaq National Market, and as a result of such transaction the Daily Net Share Settlement Value (if any) of any Securities surrendered for conversion would be in the form of such publicly traded

Change Repurchase Notice, as the case may be, has been tendered and not withdrawn in accordance with this Indenture, then, on the Repurchase Date, the Preferred Redemption Repurchase Date or the Fundamental Change Repurchase Date, as the case may
be, 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 Repurchase Price, the Preferred Redemption Repurchase Price or the Fundamental Change Repurchase
Price as aforesaid). The Company shall publicly announce the principal amount of Securities repurchased on or as soon as practicable after the Repurchase Date, the Preferred Redemption Repurchase Date or the Fundamental Change Repurchase Date, as

aggregate amount of cash deposited by the Company pursuant to this Section 3.12 exceeds the aggregate Repurchase Price, Preferred Redemption Repurchase Price or Fundamental Change Repurchase Price, as the case may be, of the Securities or
portions thereof that the Company is obligated to repurchase, then promptly after the Repurchase Date, the Preferred Redemption Repurchase Date or the Fundamental Change Repurchase Date, as the case may be, the Trustee or a Paying Agent, as the case
may be, shall return any such excess cash to the Company. 
  
 Section 3.13. Securities Repurchased in Part. 
  
 Any Security that is to be repurchased only in part shall be surrendered at the office of a Paying Agent, and promptly after the Repurchase Date, the Preferred Redemption Repurchase Date or the Fundamental Change Repurchase Date, as the
case may be, 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 repurchased. 
  

Section 3.14. Compliance with Securities Laws Upon Repurchase of Securities. 
  
 In connection with any offer to repurchase Securities under Section 3.8, 3.9 or 3.10, the Company shall (a) comply

 ARTICLE 4.

  
 CONVERSION 
  
 Section 4.1. Conversion Privilege. 
  
 (a) Subject to the further provisions of this Article 4 and
paragraph 8 of the Securities, a Holder of a Security may convert the principal amount of such Security (or any 

  

 - 31 - 








 
portion thereof equal to $1,000 or any integral multiple of $1,000 in excess thereof) into Cash and Common Stock (if any) under the circumstances and during
the periods set forth in Sections 4.1(b), 4.1(c) and 4.1(d) at the Conversion Price then in effect; provided, however, that, if such Security is submitted for redemption or repurchase pursuant to Article 3, such conversion right shall
terminate at the close of business on the second Trading Day immediately preceding the Redemption Date, the Repurchase Date, the Preferred Redemption Repurchase Date or the Fundamental Change Repurchase Date, as the case may be, for such Security or
such earlier date as the Holder presents such Security for redemption or repurchase (unless the Company shall default in making the Redemption Price, Repurchase Price, Preferred Redemption Repurchase Price or Fundamental Change 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 redeemed or repurchased). 
  
 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 Repurchase Notice, Preferred Redemption Repurchase Notice or Fundamental Change Repurchase Notice pursuant to Subsection 3.8(c), Subsection 3.9(c) or Subsection 3.10(d), as applicable, exercising the option of such Holder to require the
Company to repurchase such Security may be converted only if such Repurchase Notice, Preferred Redemption Repurchase Notice or Fundamental Change Repurchase Notice, as the case may be, is withdrawn by a written notice of withdrawal delivered to a
Paying Agent prior to 5:00 p.m., New York City time, on the second Trading Day immediately preceding the Repurchase Date, the Preferred Redemption Repurchase Date or the Fundamental Change Repurchase Date, as the case may be, in accordance with
Section 3.11. 
  
 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 4. 
  
 (b) At any time prior to the close of business on
May 15, 2010, Holders may convert their Securities only upon the occurrence of one of the following events or as provided in Section 4.1(c): 
  
 (1) if a Security has been called for redemption pursuant to Article 3 hereof, a holder may surrender such Security for conversion at any
time prior to 5:00 p.m., New York City time, on the second Trading Day immediately preceding the Redemption Date for such Security; 
  
 (2) if, after any five consecutive Trading Day period, the average of the Trading Prices for the Securities for that five-Trading Day
period was less than 98% of the average of the Conversion Values for the Securities during that period, a Holder may surrender Securities for conversion at any time during the 10 Trading Days following the later of (A) such five-Trading Day
period and (B) the date the Holder receives a Notice of Convertibility relating thereto. If a Holder provides the Company with reasonable evidence that the Trading Price for the Securities is less than 98% of the Conversion Value for the
Securities, the Company shall require the Conversion Agent to determine the Trading Price 

  

 - 32 - 








 
of the Securities for each of the five consecutive Trading Days immediately after the Company receives such evidence. In the event that the average of the
Trading Prices of the Securities during such five consecutive Trading Day period is less than 98% of the average of the Conversion Values for the Securities during such five consecutive Trading Day period, the Company shall require the Conversion
Agent to determine the Trading Prices for the Securities on each successive Trading Day until the Trading Day ending any five consecutive Trading Day period during which the average of the Trading Price for the Securities is greater than or equal to
98% of the average of the Conversion Values for the Securities during such five consecutive Trading Day period; 
  
 (3) in the event that the Company declares a dividend or distribution of any rights or warrants to all holders of Common Stock entitling
them to subscribe for or purchase shares of Common Stock at a price per share less than the Current Market Price per share (as defined in Section 4.6(g)) on the record date for such dividend or distribution (other than a distribution of rights
by the Company to its stockholders pursuant to the Company’s Rights Agreement, dated as of January 17, 2002 and amended on April 27 and April 28, 2004, between the Company and Mellon Investor Services LLC, as Rights Agent, and
any successor or similar stockholders rights plan until the occurrence of a triggering event under such plan), then the Securities may be surrendered for conversion beginning on the date the Company gives notice to the Holders of such right, which
shall not be less than 30 days prior to the ex-dividend time for such dividend or distribution, until the earlier of the close of business on the Business Day prior to the ex-dividend time or until the Company announces that such distribution will
not take place; 
  
 (4) in the event that the
Company declares a dividend or distribution of cash, debt securities (or other evidences of indebtedness) or other assets to all holders of Common Stock where the fair market value of such dividend or distribution per share of Common Stock, as
determined in this Indenture, exceeds 10% of the Current Market Price of the Common Stock as of the Trading Day immediately prior to the date of declaration for such dividend or distribution, then the Securities may be surrendered for conversion
beginning on the date the Company gives notice to the Holders of such right, which shall not be less than 30 days prior to the ex-dividend time for such dividend or distribution, until the earlier of the close of business on the Business Day prior
to the ex-dividend time or until the Company announces that such distribution will not take place; or 
  
 (5) if any event constituting a Fundamental Change (without regard to the 90% Condition) occurs, the Securities may be surrendered for
conversion during the Fundamental Change Conversion/Repurchase Period. 
  
 (c) At any time after May 15, 2008 and prior to the close of business on May 15, 2010, Holders may surrender their Securities for conversion during any Fiscal Quarter (and only during such Fiscal Quarter) if
the Closing Sale Price is equal to or greater than 150% of the Conversion Price then in effect for at least 20 Trading Days in the 30 consecutive Trading Day period ending on the last Trading Day of the immediately preceding Fiscal Quarter (it being
understood for purposes of this Section 4.1(c ) that the Conversion Price in effect at the close of business on each of the 30 consecutive Trading Days should be used). 
  

 - 33 - 








 (d) Holders may surrender their Securities for conversion at any time on or after
May 15, 2010 and prior to the close of business on the Business Day immediately preceding the Final Maturity Date. 
  
 Whenever the Securities shall become convertible pursuant to this Section 4.1, the Company or, at the Company’s request, the Trustee (or other
Conversion Agent appointed by the Company) in the name and at the expense of the Company, shall promptly notify the Holders in writing (a “Notice of Convertibility”) of the event triggering such convertibility in the manner provided
in Section 12.2, and the Company shall also publicly announce such information and publish it on the Company’s web site. Such written Notice of Convertibility and public announcement shall include: 
  
 (1) a description of such event; 
  
 (2) the periods during which the Securities shall be
convertible as provided in this Article 4 as a result of such event; 
  
 (3) the name and address of each Conversion Agent; 
  
 (4) the procedures that the Holder must follow to convert their Securities in accordance with this Article 4; and 
  
 (5) whether a Make-Whole Premium shall be payable upon
conversion of the Securities in connection with such event. 
  
 Section 4.2. Conversion Procedure. 
  
 (a) The right to convert any Security may be exercised, if such Security is represented by a Global Security, by book-entry transfer to the Conversion Agent (which initially shall be the Trustee) through the facilities of the Depositary in
accordance with the Applicable Procedures or, if such Security is represented by a Certificated Security, by delivery of such Security at the specified office of the Conversion Agent, accompanied, in either case, by (a) a completed and duly
signed conversion notice, in the form as set forth on the reverse of Security attached hereto as Exhibit A (a “Conversion Notice”); (b) if the Security is represented by a Certificated Security and such Certificated
Security has been lost, stolen, destroyed or mutilated, a notice to the Conversion Agent in accordance with Section 2.7 regarding the loss, theft, destruction or mutilation of such Security; (c) appropriate endorsements and transfer
documents if required by the Conversion Agent; and (d) payment of any tax or duty, in accordance with Section 4.4, which may be payable in respect of any transfer involving the issue or delivery of the Common Stock in the name of a Person
other than the Holder of the Security. The “Conversion Date” shall be the Business Day on which the Holder satisfies all of the requirements set forth in the immediately preceding sentence, if all such requirements shall have been
satisfied by 5:00 p.m., New York City time, on such day, and in all other cases, the Conversion Date shall be the next succeeding Business Day; provided, however, that if a Holder surrenders for conversion a Security at any time after
the twenty-fifth scheduled Trading Day prior to the Final Maturity Date, the Conversion Date shall be deemed to be the Business Day immediately preceding such Security’s Final Maturity Date. On the third Business Day following the last day of
the related Conversion Period, subject to Section 4.5, the Company 

  

 - 34 - 








 
shall deliver to the Holder through a Conversion Agent, (i) (A) provided the Conversion Agent is participating in DTC’s Fast Automated
Securities Transfer Program, such aggregate number of whole shares of Common Stock to which the applicable Holder shall be entitled to such Holder’s or its nominee’s or nominees’ balance account with DTC through its Deposit Withdrawal
Agent Commission system or (B) if the Conversion Agent is not participating in the DTC’s Fast Automated Securities Transfer Program, certificates for the number of whole shares of Common Stock, if any, to which such Holder or such
Holder’s nominee or nominees shall be entitled and (ii) and cash (including cash in lieu of any fractional shares pursuant to Section 4.3). 
  
 (b) The person in whose name the shares of Common Stock issued upon conversion 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 the 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. 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. 
  
 (c) 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. 
  
 (d) The Company shall not effect any conversion of a Security, and no Holder or any holder of an interest in a Security shall have the
right to convert any portion of such Security, to the extent that after giving effect to such conversion, such Holder or holder (together with such Holder’s or holder’s affiliates) would beneficially own in excess of 4.99% of the number of
shares of Common Stock outstanding immediately after giving effect to such conversion (the “Conversion Limitation”). For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by such Holder or
holder of an interest in a Security and its affiliates shall include the number of shares of Common Stock issuable upon conversion of a Security with respect to which the determination of such sentence is being made, but shall exclude the number of
shares of Common Stock which would be issuable upon (A) conversion of the remaining, nonconverted portion of any Security beneficially owned by such Holder or holder or any of its affiliates and (B) exercise or conversion of the
unexercised or nonconverted portion of any other securities of the Company subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by such Holder or holder or any of its affiliates. Except as
set forth in the preceding sentence, for purposes of this Section, beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act. For purposes of this Section 4.2(d), in determining the number of outstanding
shares of Common Stock, such Holder or holder may rely on the number of outstanding shares of Common Stock as reflected in (x) the Company’s most recent annual, quarterly or current report on Form 10-K, 10-Q or Form 8-K, respectively, as
the case may be; (y) a more recent public announcement by the Company or (z) any other notice by the Company setting forth the number of shares of Common Stock outstanding. For any reason at any time, 

  

 - 35 - 








 
upon the written or oral request of a Holder or a holder of an interest in a Security, the Company shall within two Business Days confirm orally and in
writing to such Holder or holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company,
including any Security, by such Holder or holder or its affiliates since the date as of which such number of outstanding shares of Common Stock was reported. By written notice to the Company, any Holder or holder of an interest in a Security may
increase or decrease the Conversion Limitation to any other percentage not in excess of 9.99% specified in such notice; provided, that (i) any such increase will not be effective until the 61st day after such notice is delivered to the Company,
and (ii) any such increase or decrease will apply only to the Holder or holder sending such notice and not to any other Holder or holder of Securities. Notwithstanding the foregoing, the Conversion Limitation shall not be applicable (i) on
any of the ten Trading Days up to and including the Final Maturity Date, or (ii) on any of the ten Trading Days up to and including the Effective Date of a Fundamental Change or (iii) during the Fundamental Change Conversion/Repurchase
Period 
  
 (e) Until Stockholder Approval shall
have been obtained, the Company may not (and shall not) issue or deliver more than 41.96 shares of Common Stock (subject to appropriate adjustment for any stock splits, stock dividends and similar events pursuant to subsection (a) of
Section 4.6) (the “Conversion Shares Cap”) for each $1,000 principal amount of Securities upon conversion thereof pursuant to Section 4.5 and/or as payment of a Make-Whole Premium with respect to such $1,000 principal
amount of Securities pursuant to Section 5.2 hereof. The provisions of this Section 4.2(e) shall limit solely the number of shares of Common Stock issuable in satisfaction of amounts owing by the Company in respect of the Conversion
Obligation and the Make-Whole Premium upon conversion of the Securities (which amounts, to the extent they exceed the Conversion Shares Cap, shall be paid in cash as herein set forth) and shall in no way be construed as a limitation on the
Conversion Price or Conversion Rate of the Securities or on the Company’s obligation to pay the Make-Whole Premium in accordance with the provisions of Article 5. 
  
 Section 4.3. Fractional Shares. 
  
 The Company will not issue fractional shares of Common Stock upon conversion of Securities. In lieu thereof, the Company
will deliver a number of shares of Common Stock equal to the aggregate of the fractional shares otherwise deliverable for each Trading Day during the Conversion Period (rounding down to the nearest whole number) and cash equal to the remainder
multiplied by the Volume Weighted Average Price of the Common Stock on the last day of the Conversion Period. 
  
 Section 4.4. 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 

  

 - 36 - 








 
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 4.5. Payment Upon Conversion.

  
 (a) In the event that the Company receives a
Holder’s Conversion Notice: 
  
 (1) For each
$1,000 aggregate principal amount of Securities surrendered for conversion, the Company shall be required to pay to such Holder the sum of the following amounts (the “Conversion Obligation”) for each of the twenty Trading Days
beginning on the third Trading Day following the Conversion Date (such twenty Trading Day period, a “Conversion Period”): 
  
 (A) if the Daily Conversion Value (as defined below) for such Trading Day for each $1,000 aggregate principal amount of Securities
exceeds $50.00, (1) a Cash payment of $50.00 and (2) the remaining Daily Conversion Value (the “Daily Net Share Settlement Value”) in shares of Common Stock; or 
  
 (B) if the Daily Conversion Value for such Trading Day for
each $1,000 aggregate principal amount of Securities is less than or equal to $50.00, a Cash payment equal to the Daily Conversion Value. 
  
 (C) For purposes of the foregoing and to give effect to the provisions of the penultimate sentence of Section 4.2(a), if a Holder
surrenders for conversion a Security at any time after the twenty-fifth scheduled Trading Day immediately preceding the Final Maturity Date, (i) the Conversion Date will be deemed to be the Business Day immediately preceding the Final Maturity
Date, (ii) the Conversion Period for such conversion will be the twenty Trading Day period commencing on the Trading Day immediately following the Final Maturity Date, and (iii) notwithstanding the provisions of the last sentence of
Section 4.2 and in lieu of receiving any Cash payments or Common Stock pursuant to clauses (A) and (B) above, such Holder shall be entitled to receive on the Final Maturity Date a Cash payment of $1,000 per $1,000 aggregate principal
amount of Securities surrendered and on the third Business Day following the last day of such Conversion Period such Holder shall be entitled to receive an amount of shares of Common Stock, if any, based on the sum of the Daily Net Share Settlement
Values for each Trading Day during such Conversion Period. 
  
 (2) The amount to be paid to a converting Holder shall be computed in accordance with the following: 
  
 (A) The “Daily Conversion Value” for each Trading Day during the Conversion Period for each $1,000 aggregate principal
amount of Securities is equal to one-twentieth of the product of the then applicable Conversion Rate multiplied by the Volume Weighted Average Price of the Common Stock (or such other form of consideration into which the Common Stock has been
converted in accordance with the provisions of Section 4.11) on such Trading Day; 
  
 (B) The number of shares of Common Stock to be delivered under Section 4.5(a)(1)(A)(2) or 4.5(a)(1)(C) calculated on each Trading
Day during the 

  

 - 37 - 








 
applicable Conversion Period, shall be determined by dividing the Daily Net Share Settlement Value by the Volume Weighted Average Price of the Common Stock
(or such other form of consideration into which the Common Stock has been converted in accordance with the provisions of Section 4.11) for such Trading Day; 
  
 (C) For purposes of this Section 4.5, “Volume Weighted Average Price” per share of
Common Stock (or any security into which the Common Stock has been converted in accordance with the provisions of Section 4.11) on any Trading Day means the volume weighted average price on the principal exchange or over-the-counter market on
which the Common Stock (or such other security) is then listed or traded, from 9:30 a.m. to 4:00 p.m. (New York City time) on that Trading Day as reported by Bloomberg, or if such Volume Weighted Average Price is not available, the Board of
Directors’ reasonable, good faith estimate of the volume weighted average price of the shares of Common Stock (or other security) on such Trading Day; 
  
 (D) Solely for purposes of valuing any non-cash consideration received by holders of Common Stock in any Change in Control, to the extent
any component of such non-cash consideration is not listed on a U.S. national or regional securities exchange or reported on Nasdaq, the value of such non-cash consideration will be determined by two independent nationally recognized investment
banks selected by the Trustee and, to the extent any component of such non-cash consideration is listed on a U.S. national or regional securities exchange or reported on Nasdaq, the value of such non-cash consideration will be determined by
reference to its Volume Weighted Average Price. 
  
 (3) To the extent the Company is precluded from issuing shares of Common Stock under clause (1) of this Section 4.5(a) upon conversion of any Securities prior to obtaining Stockholder Approval due to the Conversion Shares Cap,
then the Daily Conversion Value for any Trading Day during the applicable Conversion Period after the Conversion Shares Cap has been reached shall be paid by the Company in Cash. 
  
 (4) If such Conversion Notice shall be delivered upon a conversion in connection with a Fundamental Change
pursuant to Section 4.1(b)(5), such Holder shall be entitled to receive, in addition to any Cash, shares of Common Stock or other forms of consideration provided for in clauses (1) and (2) of this Section 4.5(a), a Make-Whole
Premium in accordance with Section 5.2. To the extent the Company is precluded from issuing shares of Common Stock as payment of a Make-Whole Premium upon conversion of any Securities prior to obtaining Stockholder Approval due to the
Conversion Shares Cap, then the Make-Whole Premium shall be paid by the Company in Cash calculated by multiplying the number of shares of Common Stock otherwise payable as such Make-Whole Premium by the applicable Stock Price. 
  
 (b) The Company shall, prior to the issuance of any
Securities hereunder, and from time to time as may be necessary, reserve at all times and keep available, free from preemptive rights, out of its authorized but unissued Common Stock, a sufficient number of shares of Common Stock deliverable upon
conversion of all of the Securities (including after taking into account any adjustment to the Conversion Price pursuant to Section 4.6). 
  

 - 38 - 








 (c) All shares of Common Stock that may be issued upon conversion of the Securities shall
be newly issued shares, shall be duly authorized, validly issued, fully paid and nonassessable and shall be free of any preemptive rights and free of any lien or adverse claim. 
  
 (d) The Company shall endeavor to comply promptly with all applicable securities laws regulating the offer
and delivery of any Common Stock upon conversion of Securities and shall list or cause to have quoted such shares of Common Stock on each national securities exchange or on Nasdaq or other over-the-counter market or such other market on which the
Common Stock is then listed or quoted. Any Common Stock issued upon conversion of a Security hereunder which at the time of conversion was a Restricted Security shall also be a Restricted Security. 
  
 Section 4.6. Adjustment of Conversion Price. 
  
 The conversion price as stated in paragraph 8 of the Securities (the
“Conversion Price”) shall be adjusted from time to time by the Company as follows: 
  
 (a) In case the Company shall pay a dividend on its Common Stock in shares of Common Stock or make a distribution on its Common Stock in
shares of Common Stock, the Conversion Price in effect immediately prior to the record date for the determination of stockholders entitled to receive such dividend or distribution shall be decreased 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 the numerator shall be the number of shares of Common Stock outstanding at the close of business on such record date and of which the
denominator shall be the sum of the number of shares of Common Stock outstanding at the close of business on such record date plus the total number of shares of Common Stock constituting such dividend or other distribution. If the Company shall
subdivide its outstanding Common Stock into a greater number of shares, or combine its outstanding Common Stock into a smaller number of shares, the Conversion Price in effect immediately prior to the day upon which such subdivision or combination
becomes effective shall be, in the case of a subdivision of Common Stock, proportionately decreased and, in the case of a combination of Common Stock, proportionately increased. 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, options 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 or exercisable or exchangeable for Common Stock) at a price per share (or having a conversion, exercise or exchange price per share) less than the Current Market Price per share of Common Stock (as
determined in accordance with subsection (g) of this Section 4.6) on the record date for the determination of stockholders entitled to receive such rights, options or warrants(or if no record date is fixed, the Business Day immediately
prior to the date of announcement of such issuance) (treating the conversion, exercise or exchange price per share of the securities convertible into or exercisable or exchangeable for Common Stock as equal to (x) the sum of (i) the price
for a unit of the security convertible into or exercisable or exchangeable for Common 

  

 - 39 - 








 
Stock and (ii) any additional consideration initially payable upon the conversion of such security into or exercise or exchange of such security for
Common Stock divided by (y) the number of shares of Common Stock initially underlying such security), 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 the numerator shall be the number of shares of Common Stock outstanding on such record date (or if no record date is fixed, the date immediately prior to the
date of announcement of such issuance) plus the number of shares which the aggregate offering price of the total number of shares of Common Stock so offered (or the aggregate conversion, exercise or exchange price of the securities so offered, which
shall be determined by multiplying the number of shares of Common Stock issuable upon conversion, exercise or exchange of such securities by the applicable conversion, exercise or exchange price per share of Common Stock pursuant to the terms of
such securities) would purchase at the Current Market Price per share (as defined in subsection (g) of this Section 4.6) of Common Stock on such record date, and of which the denominator shall be the number of shares of Common Stock
outstanding on such record date (or if no record date is fixed, the date immediately prior to the date of announcement of such issuance) plus the number of additional shares of Common Stock offered (or into which the securities so offered are
convertible, exchangeable or exercisable). Such adjustment shall be made successively whenever any such rights, options or warrants are issued and shall become effective immediately after such record date. If at the end of the period during which
such rights, options 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 exclusively in cash or (2) dividends or
distributions referred to in subsection (a) of this Section 4.6), or shall distribute to all or substantially all holders of its Common Stock rights, options or warrants to subscribe for or purchase any of its securities (excluding those
rights, options and warrants referred to in subsection (b) of this Section 4.6 and also excluding the distribution of rights to all holders of Common Stock pursuant to a Rights Plan (as defined below)), 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 (as defined in subsection (g) of
this Section 4.6) of the Common Stock on the record date mentioned below less the fair market value on such record date (as determined by the Board of Directors, 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, options 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 (as defined in subsection (g) of this Section 4.6)
of the Common Stock on such record date. Such adjustment shall be made successively whenever any such distribution is made and shall become effective 

  

 - 40 - 








 
immediately after the record date for the determination of shareholders entitled to receive such distribution. 
  
 In the event the then fair market value (as so determined) 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 is equal to or greater than the Current Market Price per share of the Common Stock on such
record date, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder of a Security shall have the right to receive upon conversion the amount of capital stock, evidences of indebtedness or other non-cash assets so
distributed or of such rights, options or warrants such Holder would have received had such Holder converted each Security on such record date. In the event that such dividend or distribution is not so paid or made, the Conversion Price shall again
be adjusted to be the Conversion Price which would then be in effect if such dividend or distribution had not been declared. If the Board of Directors determines the fair market value of any distribution for purposes of this Section 4.6(c) by
reference to the actual or when issued trading market for any securities, it must in doing so consider the prices in such market over the same period used in computing the Current Market Price of the Common Stock. 
  
 Notwithstanding the foregoing, if the securities distributed by the Company
to all or substantially all holders of its Common Stock consist of capital stock of, or similar equity interests in, a Subsidiary or other business unit, the Conversion Price shall be decreased so that the same shall be equal to the rate determined
by multiplying the Conversion Price in effect on the record date with respect to such distribution by a fraction the numerator of which shall be the average Closing Sale Price of one share of Common Stock over the Spinoff Valuation Period, and of
which the denominator shall be the sum of (x) the average Closing Sale Price of one share of Common Stock over the ten consecutive Trading Day period (the “Spinoff Valuation Period”) commencing on and including the fifth
Trading Day after the date on which “ex-dividend trading” commences on the Common Stock on the Nasdaq National Market or such other national or regional exchange or market on which the Common Stock is then listed or quoted and (y) the
average Closing Sale Price over the Spinoff Valuation Period of the portion of the securities so distributed applicable to one share of Common Stock such adjustment to become effective immediately prior to the opening of business on the fifteenth
Trading Day after the date on which “ex-dividend trading” commences. 
  
 In lieu of the foregoing, the Company may at the time of the public announcement of such distribution elect in a writing provided to the Trustee and the Holders to reserve the pro rata portion of such Securities so
that each Holder of securities shall have the right to receive upon conversion the amount of such shares of capital stock or similar equity interests of such Subsidiary or business unit that such Holder of Securities would have received if such
Holder of Securities had converted such Securities on the record date with respect to such distribution. 
  
 With respect to any rights under a preferred shares rights plan of the Company (“Rights Plan”), upon conversion of the Securities into
Common Stock, to the extent that the Rights Plan is still in effect upon such conversion, the Holders of Securities will receive, in addition to the Common Stock, the rights described therein (whether or not the rights have separated from the Common
Stock at the time of conversion), subject to the limitations set forth in any such Rights Plan (including such limitations as would be applicable to a Holder if the Holder is or becomes 

  

 - 41 - 








 
an “Acquiring Person” or “Adverse Person” as such terms are defined in the Rights Plan). If the Rights Plan provides that upon separation
of rights under such plan from the Common Stock that the Holders would not be entitled to receive any such rights in respect of the Common Stock issuable upon conversion of the Securities, the Conversion Price will be adjusted as provided in this
Section 4.6 (with such separation deemed to be the distribution of such rights), subject to readjustment in the event of the expiration, termination or redemption of the rights; provided, however, that there shall be no such
adjustment in respect of any Holder that is or becomes an “Acquiring Person” or “Adverse Person” under the Rights Plan and, in the event an adjustment to the Conversion Price shall have already been made under this paragraph in
respect of such separation of rights, it shall be readjusted and rescinded in respect of any Holder that is or becomes an “Acquiring Person” or “Adverse Person.” Any distribution of rights or warrants pursuant to a Rights Plan
complying with the requirements set forth in the immediately preceding sentence of this paragraph shall not constitute a distribution of rights or warrants pursuant to this Section 4.6(c). 
  
 Rights, options or warrants (other than rights issued pursuant to a Rights
Plan) distributed by the Company to all or substantially all holders of Common Stock entitling the holders thereof to subscribe for or purchase shares of the Company’s Capital Stock (either initially or under certain circumstances), which
rights, options or warrants, until the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such shares of Common Stock; (ii) are not exercisable; and (iii) are also
issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this Section 4.6 (and no adjustment to the Conversion Price under this Section 4.6 will be required) until the occurrence
of the earliest Trigger Event, whereupon such rights, options and warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Price shall be made under this Section 4.6(c). If any such
right, options or warrant, including any such existing rights, options or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase
different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and record date with respect to new rights, options or warrants with such
rights (and a termination or expiration of the existing rights, options or warrants without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options or warrants, or any
Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Price under this Section 4.6 was
made, (1) in the case of any such rights, options or warrants which shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Price shall be readjusted upon such final redemption or repurchase to give
effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder or holders of Common Stock with respect to such rights, options or
warrants (assuming such holder had retained such rights, options or warrants), made to all or substantially all holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights, options or warrants
which shall have expired or been terminated without exercise by any holders thereof, the Conversion Price shall be readjusted as if such rights, options and warrants had not been issued. 
  

 - 42 - 








 (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, the Conversion Price shall be reduced so that the same shall equal the price determined by dividing such Conversion Price in effect on the
record date with respect to such Cash dividend or distribution by a fraction of which the numerator shall be the Current Market Price per share of the Common Stock (as determined in accordance with subsection (g) of this Section 4.6) as of
the day before the “ex” date with respect to the dividend or distribution, and the denominator shall be such Current Market Price per share of the Common Stock (as determined in accordance with subsection (g) of this Section 4.6)
as of the day before the “ex” date with respect to the dividend or distribution less the amount per share of the Cash dividend or distribution, such decrease to become effective immediately prior to the opening of business on the day
following the date on which the Triggering Distribution is paid; provided, however, that, in the event the portion of the Triggering Distribution applicable to one share of Common Stock is equal to or greater than the Current Market
Price on such record date, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder shall have the right to receive upon conversion the amount of Cash such Holder would have received had such Holder converted each
Security on such record date. In the event that such dividend or distribution is not so paid or made, the Conversion Price shall again be adjusted to be the Conversion Price that would then be effect if such dividend or distribution had not been
declared. 
  
 (e) In case any tender offer made
by the Company or any of its Subsidiaries 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 determined by the Board of Directors, whose determination shall be conclusive evidence thereof and which shall be evidenced by an Officers’ Certificate delivered to the Trustee
thereof) of any other consideration) that exceeds an amount equal to the Current Market Price per share of Common Stock (as determined in accordance with subsection (g) of this Section 4.6) 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”), 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 (as determined in accordance with subsection (g) of this Section 4.6) 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 (as determined in accordance with subsection (g) of this Section 4.6) on the
Trading Day next succeeding the Expiration Date, such reduction to become effective immediately prior to the opening of business 

  

 - 43 - 








 
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 4.6(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 4.6(e).

  
 For purposes of this Section 4.6(e), the term
“tender offer” shall mean and include both tender offers and exchange offers, 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) In case the Company shall issue, prior to
June 3, 2006, shares of Common Stock (or securities convertible into Common Stock) at a price per share (or having a conversion price per share) less than $13.45 (subject to adjustment in the same manner as the Conversion Price is adjusted
pursuant to this Section 4.6) (treating the conversion price per share of the securities convertible into Common Stock as equal to (x) the sum of (i) the price for a unit of the security convertible into Common Stock and (ii) any
additional consideration initially payable upon the conversion of such security into Common Stock divided by (y) the number of shares of Common Stock initially underlying such security), 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 the date of such issuance by a fraction of which the numerator shall be the number of shares of Common Stock
outstanding on such date plus the number of shares which the aggregate issuance price of the total number of shares of Common Stock so issued (or the aggregate conversion price of the convertible securities so issued, 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 $13.45 per share of
Common Stock (subject to adjustment in the same manner as the Conversion Price is adjusted pursuant to this Section 4.6), and of which the denominator shall be the number of shares of Common Stock outstanding on such date plus the number of
additional shares of Common Stock issued (or into which the convertible securities so issued are convertible). Such adjustment shall be made successively whenever any such Common Stock (or securities convertible into Common Stock) are issued and
shall become effective immediately after issuance. If at the end of the period during which any such securities convertible into Common Stock are convertible not all such securities shall have been converted, 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 upon conversion of such convertible securities. Notwithstanding the foregoing provisions of this Section 4.6(f),
(i) no adjustment to the Conversion Price shall be required to be made hereunder in respect of the first $25 million of Common Stock (or securities convertible into Common Stock) issued after the date hereof at a price per share (or having a
conversion price per share) less than $13.45 (subject to adjustment in the same manner as the Conversion Price is adjusted pursuant to this Section 4.6), and (ii) no adjustment to the Conversion Price shall be required to be made hereunder
unless a similar 

  

 - 44 - 








 
adjustment to the conversion price of the Series B Preferred Stock is required to be made under Sections 5(b)(iii) and 5(b)(iv) of the Certificate of
Designations of the Series B Preferred Stock as in effect on the date hereof. The provisions of this Section 4.6(f) shall expire and be of no further force or effect on June 3, 2006. Until such time as the Company receives the Stockholder
Approval, no adjustment shall be made pursuant to this Section 4.6(f) that shall cause the Conversion Price to be less than $[            ] [Insert price equal to closing Bid Price
plus 12.5¢ per Warrant Share] (subject to adjustment in the same manner as the Conversion Price is adjusted pursuant to Section 4.6(a) hereof) (the “Series B Limitation”); provided, however, upon receipt of the
Stockholder Approval, any adjustment previously required pursuant to this Section 4.6(f) that was not made by reason of the Series B Limitation shall immediately take effect. 
  
 (g) For the purpose of any computation under subsections (b), (c), (d) or (e) of this
Section 4.6, the current market price (the “Current Market Price”) shall mean, with respect to any date of determination, the average of the Closing Sale Prices per share of Common Stock for the ten consecutive Trading Days
ending on the date of determination. For purposes hereof, the term “ex” date, when used with respect to any dividend or distribution, means the first date on which the Common Stock trades, regular way, on the relevant exchange or in the
relevant market from which the Closing Sale Price was obtained without the right to receive such dividend or distribution. 
  
 (h) In any case in which this Section 4.6 shall require that an adjustment be made following a record date or Expiration Date, as the
case may be, established for purposes of this Section 4.6, 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 4.9) issuing to the
Holder of any Security converted after such record 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, or Cash payable, upon such conversion only on the basis of the Conversion Price prior to adjustment; and, in lieu of the shares the issuance of which, or Cash the payment of which, is so deferred, the Company shall issue or cause
its transfer agents to issue due bills or other appropriate evidence prepared by the Company of the right to receive such shares or Cash, as the case may be. If any distribution in respect of which an adjustment to the Conversion Price is required
to be made as of the record 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 Expiration Date had not occurred. 
  
 (i) For purposes of this Section 4.6, “record date” shall mean, with respect to any dividend, distribution or other transaction or event in which the holders of Common Stock have the right to receive
any cash, securities or other property or in which the Common Stock (or other applicable security) is exchanged or converted into any combination of cash, securities or other property, the date fixed for determination of stockholders entitled to
receive such cash, security or other property (whether or not such date is fixed by the Board of Directors or by statute, contract or otherwise). 
  

 - 45 - 








 Section 4.7. 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 4.7 are not required to be made shall be carried forward and taken into account in any subsequent
adjustment and, in any event, shall be carried forward and taken into account regardless of whether the aggregate adjustment is less than 1% upon the announcement by the Company of a Fundamental Change, upon any Repurchase Date, upon any notice of
redemption of the Securities and at the Final Maturity Date. All calculations under this Article 4 shall be made to the nearest cent or to the nearest one-hundredth of a share, as the case may be. 
  
 Except as otherwise provided herein, 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
4.8. Adjustment for Tax Purposes. 
  
 The Company shall be
entitled to make such reductions in the Conversion Price, in addition to those required by Section 4.6, as it in its discretion shall determine to be advisable in order to avoid or diminish any tax to stockholders in connection with 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. 
  
 Section 4.9. 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 4.10. Notice of Certain Transactions.

  
 In the event that: 
  
 (a) the Company takes any action which would require an
adjustment in the Conversion Price; 
  
 (b) the
Company consolidates or merges with, or transfers all or substantially all of its property and assets to, another corporation and stockholders of the Company must approve the transaction; or 
  

 - 46 - 








 (c) 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 10 days before such proposed date. Failure to mail such notice or any defect therein shall not affect the validity of any transaction referred to in clause (a),
(b) or (c) of this Section 4.10. 
  
 Section 4.11.
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 4.6); (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 or conveyance as an entirety or substantially as an entirety of the property and assets of the Company, directly or indirectly, to any person, then
the Company, or such successor, purchasing or transferee corporation, as the case may be, shall, as a condition precedent to such reclassification, change, combination, consolidation, merger, sale or conveyance, execute and deliver to the Trustee a
supplemental indenture providing that (A) the Holder of each Security then outstanding shall have the right to convert such Security into cash and, with respect to the portion of the Conversion Obligation in excess (if any) of the principal
amount of Securities being converted, the kind and amount of shares of stock and other securities and property (including cash) receivable upon such reclassification, change, combination, consolidation, merger, sale or conveyance 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 or conveyance (provided that, if the type or amount of shares of stock and
other securities and property (including cash) receivable upon such reclassification, change, combination, consolidation, merger, sale or conveyance is more than a single type of consideration (determined based in part upon any form of stockholder
election), then the type and amount of consideration will be deemed to be the weighted average of the kind and amounts of consideration received by the holders of the Company’s Common Stock that affirmatively make such an election) and
(B) any additional shares of Common Stock which a Holder is entitled to receive as a Make-Whole Premium upon conversion in connection with a Fundamental Change, shall not be payable in shares of Common Stock, but will represent a right to
receive the kind and amount of shares of stock and other securities and property (including cash) receivable upon such reclassification, change, combination, consolidation, merger, sale or conveyance by a holder of the additional shares of Common
Stock had such additional shares of Common Stock been outstanding immediately prior to such reclassification, change, combination, consolidation, merger, sale or conveyance. 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 4. If, in the case of any such consolidation, merger, combination, sale or conveyance, the stock or other
securities and property (including cash) receivable thereupon by a holder of Common Stock 

  

 - 47 - 








 
include shares of stock or other securities and property of a person other than the successor, purchasing or transferee corporation, as the case may be, in
such consolidation, merger, combination, sale or conveyance, then such supplemental indenture shall also be executed by such other person and shall contain such additional provisions to protect the interests of the Holders of the Securities as the
Board of Directors shall reasonably consider necessary by reason of the foregoing. The provisions of this Section 4.11 shall similarly apply to successive reclassifications, changes, combinations, consolidations, mergers, sales or conveyances.

  
 In the event the Company shall execute a supplemental
indenture pursuant to this Section 4.11, 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 or conveyance, any adjustment to be made with respect thereto and that
all conditions precedent have been complied with and (y) an Opinion of Counsel that all conditions precedent have been complied with, and shall promptly mail notice thereof to all Holders. 
  
 Section 4.12. Trustee’s Disclaimer. 
  
 The Trustee shall have no duty to determine when an adjustment under this
Article 4 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 4.9. 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 4. 
  
 The Trustee shall not be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture executed pursuant
to Section 4.11, 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 4.11. 
  
 Section 4.13. Voluntary
Reduction. 
  
 The Company from time to time may reduce the
Conversion Price by any amount for any period of time if the period is at least 20 days and if the reduction is irrevocable during the period if the Board of Directors determines that such reduction would be in the best interest of the Company or to
avoid or diminish income tax to holders of shares of the Common Stock in connection with a dividend or distribution of stock or similar event, and the Company provides 15 days prior notice of any reduction in the Conversion Price; provided,
however, that in no event may the Company reduce the Conversion Price to an amount that is less than the par value of a share of Common Stock.

 ARTICLE 5. 
  

PAYMENT OF INTEREST AND MAKE-WHOLE PREMIUM 
  
 Section 5.1. Interest Payments. 
  
 (a) The Company shall pay interest on the Securities at the rate of 5.0% per annum. The Company shall pay interest semiannually in
arrears on May 15 and November 15 of each year, commencing May 15, 2006. 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 November __, 2005;
provided, however, that if there is not an existing default in the payment of interest and if a Security is authenticated between a Regular Record Date 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, comprised of twelve 30 day months. In the event of the maturity, conversion, redemption or repurchase of a Security by the Company at the option of the Holder, interest
shall cease to accrue on such Security. 
  
 (b)
Upon conversion of a Security, (i) a Holder shall not receive any cash payment of interest (unless such conversion occurs between a Regular Record Date and the Interest Payment Date to which it relates, in which case a Holder at the close of
business on the Regular Record Date will receive on the Interest Payment Date accrued and unpaid interest) and the Conversion Price shall not be adjusted to account for accrued and unpaid interest and (ii) except as set forth in clause
(c) below, the Company’s delivery to a Holder of cash and shares of Common Stock, if any, into which the Security is convertible shall be deemed to satisfy its obligation with respect to such Security, and any accrued but unpaid interest
shall be deemed to be paid in full upon conversion, rather than cancelled, extinguished or forfeited. 
  
 (c) Securities surrendered for conversion by a Holder after the close of business on any Regular Record Date but prior to the next
Interest Payment Date must be accompanied by payment of an amount equal to the interest that has accrued on the Securities being converted (other than overdue interest, if any, that has accrued on such Security) for the interest period ending on
such Interest Payment Date, unless such Security has been called for redemption by the Company pursuant to Article 3. 
  
 Section 5.2. Make-Whole Premium. 
  
 (a) If a Fundamental Change occurs prior to November 15, 2010, the Company shall pay the Make-Whole Premium to Holders of the
Securities who convert their Securities in connection with a Fundamental Change pursuant to Section 4.1(b)(5) at any time during the Fundamental Change Conversion/Repurchase Period. The Make-Whole Premium shall be paid on the Effective Date of
the Fundamental Change (or, in the event the Securities are converted after the Effective Date but during the Fundamental Change Conversion/Repurchase Period, on the third Business Day following the end of the Fundamental Change
Conversion/Repurchase Period) and shall be paid solely in shares of the Common Stock (other than Cash paid in lieu of fractional shares) or in the same form of consideration into which all or substantially all of the shares of Common Stock have been
converted or exchanged in connection with the Fundamental Change, as described below. The Make-Whole Premium shall be equal to 

  

 - 49 - 








 
an additional number of shares of Common Stock calculated in accordance with Section 5.2(b) hereof. The Make-Whole Premium will be in addition to, and
not in substitution for, any Cash, securities or other assets otherwise due to Holders of Securities upon conversion as described in this Indenture. 
  
 (b) The “Make-Whole Premium” shall be equal to the principal amount of the Securities to be converted divided by $1,000
and multiplied by the applicable number of shares of Common Stock determined by reference to the table below (the “Make-Whole Premium Table”) and is based on the Effective Date and the Stock Price.

The exact Stock Price and Effective Date may not be set forth on the Make-Whole Premium Table, in which case, if the Stock Price is between two Stock Prices on the Make-Whole Premium Table or the Effective Date is between two Effective Dates on the
Make-Whole Premium Table, the Make-Whole Premium shall be determined by straight-line interpolation between Make-Whole Premium amounts set forth for the higher and lower Stock Prices and the two Effective Dates, as applicable, based on a 365-day
year (or a 366-day year if the Effective Date occurs in a leap year). The Stock Prices set forth in the column headers are subject to adjustment pursuant to Section 5.3. 
  
 (A) (2) If the Stock Price is less than or equal to $12.49 (subject to adjustment pursuant to
Section 5.3, the “Stock Price Threshold”), the Make-Whole Premium shall be equal to zero shares of Common Stock. 
  
 (B) (3) If the Stock Price is equal to or greater than $37.51 (subject to adjustment pursuant to Section 5.3, the “Stock
Price Cap”), the Make-Whole Premium shall be equal to zero shares of Common Stock. 
  
 (C) (4) “Stock Price” means the price paid per share of Common Stock in the transaction constituting the Fundamental
Change, determined as follows: 

  

 - 50 - 








 
(i) if holders of Common Stock receive only Cash in the transaction constituting the Fundamental Change, the Stock Price shall equal the cash amount paid per
share of Common Stock; and (ii) in all other cases, the Stock Price shall equal the arithmetic average of the Closing Sale Prices of a share of Common Stock over the five Trading Day period ending on the fifth Trading Day immediately preceding
the Effective Date; and “Effective Date” means the date that a Fundamental Change becomes effective. 
  
 (c) The Company shall pay the Make-Whole Premium solely in shares of Common Stock (other than Cash paid in lieu of fractional shares) or
in the same form of consideration into which all or substantially all of the shares of Common Stock have been converted or exchanged in connection with the Fundamental Change. If holders of the Common Stock receive or have the right to receive more
than one form of consideration in connection with such Fundamental Change, then, for purposes of the foregoing, the forms of consideration in which the Make-Whole Premium shall be paid shall be in proportion to the different forms of consideration
paid to holders of Common Stock in connection with such Fundamental Change. 
  
 (d) The Company shall, from time to time, appoint an independent nationally recognized investment bank to serve as calculation agent with respect to calculation of the Make-Whole Premium (the “Calculation
Agent”). The Calculation Agent shall, on behalf of and on request by the Company, calculate (A) the Stock Price and (B) the Make-Whole Premium with respect to such Stock Price, based on the Effective Date specified by the Company,
and shall deliver its calculation of the Stock Price and Make-Whole Premium to the Company and the Trustee within three Business Days of the request by the Company or the Trustee. The Company or, at the Company’s request, the Trustee, in the
name and at the expense of the Company, (X) shall notify the Holders of the Stock Price and Make-Whole Premium with respect to a Fundamental Change as part of the Fundamental Change Repurchase Notice or otherwise in accordance with the notice
provisions of the Indenture and (Y) shall notify the Holders, promptly upon the opening of business on the Effective Date of the number of shares of Common Stock (or such other securities, assets or property (including Cash) into which all or
substantially all of the shares of Common Stock have been converted as of the Effective Date as described above) to be paid in respect of the Make-Whole Premium in connection with such Fundamental Change, in the manner provided in this Indenture.
The Company shall verify, in writing, all calculations made by the Calculation Agent pursuant to this Section 5.2(d). 
  
 (e) On or prior to the Fundamental Change Repurchase Date, the Company shall deposit with the Trustee or with one or more Paying Agents
(or, if the Company or an Affiliate or Subsidiary of the Company is acting as the Paying Agent, set aside, segregate and hold in trust) a number of shares of Common Stock (or, in the case of a Fundamental Change in which all or substantially all of
the shares of Common Stock have been, as of the Effective Date, converted into or exchanged for the right to receive securities or other assets or property (including Cash), an amount of such other securities or other assets or property (including
Cash)) sufficient to pay the Make-Whole Premium with respect to all the Securities converted in connection with such Fundamental Change; provided, that, if such payment is made on the Fundamental Change Repurchase Date, it must be received by
the Trustee or Paying Agent, as the case may be, by 11:00 a.m., New York City time, on such date. Payment of the Make-Whole Premium for Securities surrendered for conversion during the Fundamental Change Conversion/Repurchase Period shall be made
promptly on the Fundamental Change Repurchase

Company shall publish a notice containing this information in a newspaper published in the English language, customarily published each Business Day and of general circulation in the City of New York or publish such information on the Company’s
website or through such other public medium as the Company may use at that time. 
  
 Section 5.3. Adjustments Relating to Make-Whole Premium. 
  
 Whenever the Conversion Price shall be adjusted from time to time by the Company pursuant to Section 4.6, the Stock Price Threshold and the Stock
Price Cap shall be adjusted and each of the Stock Prices set forth in the Make-Whole Premium Table shall be adjusted. The adjusted Stock Price Threshold, Stock Price Cap and Stock Prices set forth in the Make-Whole Premium Table shall equal the
Stock Price Threshold, Stock Price Cap and such Stock Prices, as the case may be, immediately prior to such adjustment multiplied by a fraction, the numerator of which is the Conversion Price as so adjusted and the denominator of which is the
Conversion Price immediately prior to the adjustment giving rise to such adjustment. Each of the share amounts set forth in the body of the Make-Whole Premium Table shall also be adjusted in the same manner and at the same time.

 During the period beginning on the date on which any of the Securities are
originally issued and ending on the date that is two years from such date, the Company shall not, and shall use its best efforts not to permit any of its “affiliates” (as defined under Rule 144) to, resell any Securities which constitute
“restricted securities” under Rule 144 that have been reacquired by any of them. The Trustee shall have no responsibility in respect of the Company’s performance of its agreement in the preceding sentence. 
  
 Section 6.8. Stay, Extension and Usury Laws. 
  
 The Company covenants (to the extent that it may lawfully do so) that it

(iii) the date on which such Liquidated Damages are payable. Unless and until a Trust Officer of the Trustee receives such a certificate, the Trustee may assume without inquiry that no such Liquidated Damages are payable. If the Company has
paid Liquidated Damages directly to the Persons entitled to such Liquidated Damages, the Company shall deliver to the Trustee a certificate setting forth the particulars of such payment. 
  
 Section 6.11. Incurrence of Indebtedness.

Indebtedness to a Person that is not either the Company or a Subsidiary thereof shall be deemed, in each case, to constitute an incurrence of such Indebtedness by the Company or such Subsidiary, as the case may be, that was not permitted by this
clause (5); 
  
 (6) Indebtedness in an aggregate

 (17) the guarantee of any Indebtedness otherwise permitted
by this Indenture to be incurred. 
  

 - 58 - 








 Subject to the next succeeding paragraph below, for purposes of clarification, all Indebtedness incurred
under clause (14) or (15) of the definition of Permitted Indebtedness shall continue to be Permitted Indebtedness for so long as such Indebtedness shall remain outstanding regardless of whether that Indebtedness would be permitted to be
incurred under clause (14) or (15) of such definition as of any date subsequent to the date of incurrence of such Indebtedness. 
  
 Notwithstanding the foregoing, any Permitted Indebtedness that is unsecured at the time of incurrence and becomes secured on any date thereafter (such
date, the “Secured Date”) shall cease to be Permitted Indebtedness hereunder unless such Indebtedness could have been incurred as secured Permitted Indebtedness on the Secured Date. 
  
 For purposes of determining compliance with this Section 6.11,
(i) in the event that an item of Indebtedness meets the criteria of more than one of the types of Indebtedness included in the definition of Permitted Indebtedness, the Company, in its sole discretion, may classify such item of Indebtedness at
the time of its incurrence and only be required to include the amount and type of such Indebtedness in one of the clauses of such definition and (ii) an item of Indebtedness may be divided and classified in more than one of the types of
Indebtedness included in the definition of Permitted Indebtedness. 
  
 “Acquired Indebtedness” means, with respect to any specified Person, Indebtedness of any other Person (i) existing as of the time such other Person is merged with or into or became a Subsidiary of such specified Person
or (ii) assumed by the specified Person in connection with an acquisition of assets. 
  
 “Indebtedness” of any Person means, at any date, without duplication, (i) all obligations of such Person for borrowed money, (ii) all obligations of such Person evidenced by bonds,
debentures, notes or other similar instruments, (iii) all obligations of such Person to pay the deferred purchase price of property or services, all conditional sale obligations and all obligations under any title retention agreement,
(iv) all obligations of such Person as lessee which are capitalized in accordance with GAAP, (v) all obligations of others which are secured by a Lien on any asset of such Person (the amount of such obligations being deemed to be the
lesser of the fair market value of such asset or the amount of the obligations so secured), whether or not such Person is otherwise liable for such obligations, (vi) all obligations of others which are, directly or indirectly, guaranteed by
such Person or for which such Person has agreed (contingently or otherwise) to assure a creditor against loss, including without limitation, through an agreement to purchase or otherwise acquire such obligations, (vii) all reimbursement and
other obligations with respect to letters of credit, bankers’ acceptances, surety bonds or similar credit transactions, whether or not matured, (viii) all obligations of such Person under commodity price hedging arrangements, in each case
whether contingent or matured, (ix) all obligations of such Person under any foreign exchange contract, currency swap agreement, interest rate swap, cap or collar agreement or other similar agreement or arrangement designed to alter the risks
of that Person arising from fluctuations in currency values or interest rates, in each case whether contingent or matured, (x) all obligations in respect of financial instruments which are classified as a liability on the balance sheet of such
Person and (xi) all Disqualified Equity Interests issued by such Person (with the amount of Indebtedness represented by such Disqualified Equity Interests being equal to the greater of its voluntary or involuntary liquidation preference and its
maximum fixed repurchase price, but excluding accrued dividends, if any). 

  

 - 59 - 








 
For purposes hereof, the “maximum fixed repurchase price” of any Disqualified Equity Interests which does not have a fixed repurchase price
shall be calculated in accordance with the terms of such Disqualified Equity Interests as if such Disqualified Equity Interests were repurchased on any date on which Indebtedness shall be required to be determined pursuant to this Indenture, and if
such price is based upon, or measured by, the fair market value of such Disqualified Equity Interests, such fair market value shall be determined reasonably and in good faith by the board of directors of the issuer of such Disqualified Equity
Interests. The amount of any Indebtedness outstanding as of any date shall be (i) the outstanding balance at such date of all unconditional obligations, together with any interest thereon that is more than 30 days past due, or the accreted
value thereof, in the case of any Indebtedness issued with original issue discount, or (ii) with respect to contingent obligations, the maximum liability upon the occurrence of the contingency giving rise to the obligation. 
  
 “Disqualified Equity Interest” means any Capital Stock that,
by its terms (or by the terms of any security into which it is convertible, or for which it is exchangeable or exercisable, at the option of the holder thereof), or upon the happening of any event, matures or is mandatorily redeemable, pursuant to a
sinking fund obligation or otherwise, or redeemable at the sole option of the holder thereof, in whole or in part, prior to 91 days after November 15, 2010, for cash or is convertible into or exchangeable or exercisable for debt securities of
the Company or any its Subsidiaries at any time prior to such date. Notwithstanding the preceding sentence, any Capital Stock that would constitute Disqualified Equity Interests solely because the holders of the Capital Stock have the right to
require the Company to repurchase such Capital Stock upon the occurrence of a change of control will not constitute a Disqualified Equity Interest if the terms of such Capital Stock provide that the definition of change of control for the purposes
of such Capital Stock is the same as the definition of Change of Control under this Indenture and that the Company may not repurchase or redeem any such Capital Stock pursuant to such provisions unless prior to such repurchase or redemption, the
Company shall have repurchased the Securities required to be repurchased under Section 3.10 hereof. 
  
 “Permitted Purchase Money Security Interest” means any Lien on any property or asset created, issued or assumed to secure Indebtedness
incurred, assumed or issued to satisfy, in whole or in part, the purchase price of such property or asset (including installation costs) and expenditures made for any construction, development or improvements performed thereon or added thereto,
provided that such Lien, or any agreement or other instrument under which such Lien is constituted, is limited to (and any Indebtedness incurred in connection therewith does not exceed 85% of the fair market value of) the property or asset acquired
in connection with the assumption, issuance or incurring of such Indebtedness and is created, issued or assumed concurrently with the acquisition of such property or assets. 
  
 “Liens” means, with respect to any asset, any mortgages, pledges, liens, charges, security agreements or
other encumbrances of any kind in respect of such asset (whether or not filed, recorded or otherwise perfected under applicable law) or any other arrangements that in substance secure payment or performance of an obligation, statutory and other
non-consensual liens or encumbrances and includes the interest of a vendor or lessor under any conditional sale agreement, capital lease or other title retention agreement.

 “EBITDA” means, with respect to the Company for any applicable period, the Net Income of
the Company and its Subsidiaries for such period plus (without duplication) the sum of the following amounts for the Company and its Subsidiaries for such period and to the extent deducted in determining Net Income for such period:
(1) Interest Expense, (2) income tax expense, (3) depreciation expense, (4) amortization expense, (5) non-recurring cash transaction costs incurred in connection with any acquisition in an amount not exceeding $2,000,000 in
the aggregate during such period, (6) non-recurring cash severance costs in an amount not exceeding $10,000,000 in the aggregate during such period and (7) all other non-cash charges (excluding any such non-cash charge to the extent that
it represents an accrual of or reserve for cash expenditures in any future period), determined on a consolidated basis in accordance with GAAP. If since the beginning of the applicable period the Company or any of its Subsidiaries shall have
acquired assets constituting all or substantially all of a product line or an operating unit of a business or shall have acquired (by merger or otherwise) any corporation or other person which becomes a Subsidiary, EBITDA for such period shall be
calculated after giving pro forma effect thereto as if such acquisition occurred (and any Acquired Indebtedness in connection with such acquisition was incurred) on the first day of such period. If since the beginning of the applicable period the
Company or any of its Subsidiaries shall have disposed of assets constituting all or substantially all of a product line or an operating unit of a business or shall have disposed of any Capital Stock of any Subsidiary such that after giving effect
to such disposition such Subsidiary ceases to constitute a Subsidiary hereunder, EBITDA for such period shall be calculated after giving pro forma effect thereto as if such disposition occurred on the first day of such period. 
  
 “Net Income” means, with respect to the Company for any
applicable period, the net income of the Company and its Subsidiaries for such period determined on a consolidated basis and in accordance with GAAP; provided, however, that the calculation of Net Income shall exclude the net income, if any, from
any contract revenue and related contract expense recognized during such period. 
  
 “Interest Expense” means, with respect to the Company for any applicable period, the total interest expense of the Company and its Subsidiaries for such period determined on a consolidated basis and
in accordance with GAAP. 
  
 “Permitted Refinancing
Indebtedness” means any Indebtedness of the Company or any of its Subsidiaries issued in exchange for, or the net proceeds of which are used to extend, refinance, renew, replace, defease, repay, prepay, redeem, retire or refund other
Indebtedness of the Company or any of its Subsidiaries (other than intercompany Indebtedness); provided that: 
  
 (i) the principal amount (or accreted value, if applicable) of such Permitted Refinancing Indebtedness does not exceed the principal
amount of (or accreted value, if applicable), plus fees, expenses, premiums, defeasance costs and accrued interest on, the Indebtedness so extended, refinanced, renewed, replaced, defeased, repaid, prepaid, redeemed, retired or refunded; 

 
 (ii) such Permitted Refinancing Indebtedness has a final
maturity date later than the final maturity date of, and has a Weighted Average Life to Maturity equal to or greater than the Weighted Average Life to Maturity of, the Indebtedness 

  

 - 61 - 








 
being extended, refinanced, renewed, replaced, defeased, repaid, prepaid, redeemed, retired or refunded; 
  
 (iii) if the Indebtedness being extended, refinanced,
renewed, replaced, defeased, repaid, prepaid, redeemed, retired or refunded is subordinated in right of payment to the Securities, then the Permitted Refinancing Indebtedness must be subordinated in right of payment to the Securities on terms at
least as favorable, taken as a whole, to the Securityholders as those contained in the documentation governing the Indebtedness being extended, refinanced, renewed, replaced, defeased, repaid, prepaid, redeemed, retired or refunded; and 

 
 (iv) if the Indebtedness being extended, refinanced,
renewed, replaced, defeased, repaid, prepaid, redeemed, retired or refunded is secured, then the Permitted Refinancing Indebtedness is not secured by any property or assets of the Company and its Subsidiaries other than the property and assets that
secured the Indebtedness being extended, refinanced, renewed, replaced, defeased, repaid, prepaid, redeemed, retired or refunded; and 
  
 (v) such Indebtedness is incurred either by the Company or by the Subsidiary who is the obligor on the Indebtedness being extended,
refinanced, renewed, replaced, defeased, repaid, prepaid, redeemed, retired or refunded. 
  
 “Weighted Average Life to Maturity” means, when applied to any Indebtedness at any date, the number of years obtained by dividing (i) the sum of the products obtained by multiplying (a) the
amount of each then remaining installment, sinking fund, serial maturity or other required payments of principal, including payment at final maturity, in respect thereof, by (b) the number of years (calculated to the nearest one-twelfth) that
will elapse between such date and the making of such payment, by (ii) the then outstanding principal amount of such Indebtedness. 
  
 Section 6.12. Stockholder Approval. 
  
 The Company agrees to use its reasonable best efforts to seek and obtain affirmative approval in accordance with the Company’s Certificate of
Incorporation and the rules of The Nasdaq Stock Market at the next special or annual meeting of its stockholders, which shall be held no later than May 31, 2006, for the issuance of a number of shares of Common Stock sufficient to fully provide

Conversion Shares Cap and Exercise Shares Cap (as defined in the Warrants) (such affirmative approval being referred to as the “Stockholder Approval”). If the Company shall not obtain the Stockholder Approval at its next meeting of
stockholders, the Company shall use its reasonable best efforts to obtain such approval at each succeeding meeting of its stockholders until such time as it shall have obtained approval for the issuance of a number of shares of Common Stock
sufficient to fully provide for the conversion of the Securities and the exercise of the Warrants. Upon receipt by the Company of the Stockholder Approval, the Company shall deliver a written notice thereof

acceleration, have been cured or waived; (b) to the extent the payment of such interest is lawful, interest (calculated at the rate per annum borne by the Securities) on overdue installments of interest and overdue principal, which has become

Securities or this Indenture. 
  
 (b) 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 Holder in exercising any right or remedy accruing upon an Event of Default shall
not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be
deemed expedient, by the Trustee or by the Holders, as the case may be. 
  

 - 66 - 








 (c) No remedy is exclusive of any other remedy. All available remedies are cumulative to
the extent permitted by law. The assertion or employment of any right or remedy hereunder shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. 
  
 Section 8.4. Waiver of Defaults and Events of Default. 
  
 Subject to Sections 8.7 and 11.2, the Holders of a majority in aggregate
principal amount of the Securities then outstanding by notice to the Trustee may waive an existing default or Event of Default and its consequences, except a default or Event of Default in the payment of the principal of, or interest and any

 The Holders of a majority in aggregate principal amount of the Securities
then outstanding may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with
law or this Indenture, that the Trustee determines may be unduly prejudicial to the rights of another Holder or the Trustee, or that may involve the Trustee in personal liability unless the Trustee is furnished indemnity reasonably satisfactory to
it; provided, however, that the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.

Holder. 
  
 Section 8.7. Rights of Holders to Receive Payment
and to Convert. 
  
 Notwithstanding any other provision of
this Indenture, the right of any Holder of a Security to receive payment of the principal of, or interest and any premium, including any Make-Whole Premium, and Liquidated Damages, if any, on, the Security on or after the respective due dates

Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 9.7, and to the extent that such payment of the reasonable compensation, expenses, disbursements and advances in any such proceedings shall be denied for any reason, payment of the same shall be secured by
a lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other property which the Holders may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or

 - 68 - 








 
any Holder, to authorize, accept or adopt, any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any
Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

 Section 11.3. Compliance with Trust Indenture Act. 
  
 Every amendment to or supplement of this Indenture or the Securities shall comply with the TIA as in effect at the date of such amendment or supplement. 
  
 Section 11.4. Revocation and Effect of Consents. 
  
 (a) Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a continuing
consent by the Holder and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent is not made on any Security. However, any such Holder or
subsequent Holder may revoke the consent as to its Security or portion of a Security if the Trustee receives the notice of revocation before the date the amendment, supplement or waiver becomes effective. 
  
 (b) After an amendment, supplement or waiver becomes
effective, it shall bind every Securityholder, unless it makes a change described in any of clauses (1) through (13) of Subsection 11.2(a). In that case the amendment, supplement or waiver shall bind each Holder of a Security who has
consented to it and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security.

 Section 11.5. Notation on or Exchange of Securities. 
  
 If an amendment, supplement or waiver 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 about 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. 
  
 Section 11.6. Trustee To Sign Amendments, Etc. 
  
 The Trustee shall sign any amendment or supplemental indenture authorized pursuant to this Article 11 if the amendment or supplemental indenture does not
adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may, in its sole discretion, but need not sign it. In signing or refusing to sign such amendment or supplemental indenture, the Trustee shall be
entitled to receive, and, subject to Section 9.1, shall be fully protected in relying upon, an Opinion of Counsel stating that such amendment or supplemental indenture is authorized or permitted by this Indenture. The Company may not sign an
amendment or supplement indenture until the Board of Directors approves it. 
  
 Section 11.7. Effect of Supplemental Indentures. 
  
 Upon the execution of any supplemental indenture under this Article, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; and
every Holder of Securities theretofore or thereafter authenticated and delivered hereunder shall be bound thereby.
