(a) Subject to compliance with any applicable additional requirements contained in Section 2.12, when a Security is presented to the 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 attached hereto and in form satisfactory to the Registrar and each 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 registration of transfer or exchange at an office or agency maintained for such purpose 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 transfer or exchange shall be without charge, except that the Company or the Registrar may require payment of a sum sufficient to pay all taxes, assessments or other governmental charges that may be imposed in connection with the transfer or exchange of the Securities from the Holder requesting such transfer or exchange.

Section 2.7 Replacement Securities.

If (a) any mutilated Security is surrendered to the Company, the Registrar or the Trustee, or (b) the Company, the 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 Registrar and the Trustee such security or indemnity as may be requested by them to save each of them harmless, then, in the absence of any notice to the Company, the 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 certificate number not contemporaneously outstanding.

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 by the Company pursuant to ARTICLE III or repurchased by the

II-B-19

Company pursuant to ARTICLE IV or ARTICLE V, the Company in its discretion may, instead of issuing a new Security, pay, redeem or repurchase such Security, as the case may be.

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, assessment or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee or the Registrar) connected therewith.

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 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.

The provisions of this Section 2.7 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities.

Section 2.8 Outstanding Securities; Determinations of Holders’ Action.

Securities outstanding at any time are all the Securities authenticated by the Trustee, except for those cancelled by it, those delivered to it for cancellation, and those described in this Section 2.8 as not outstanding. If a Security is replaced pursuant to Section 2.7, the replaced Security ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Security is held by a bona fide purchaser unaware that such Security has been replaced.

Subject to Section 2.12(f), a Security does not cease to be outstanding because the Company or an Affiliate thereof holds the Security; provided, however, that in determining whether the Holders of the requisite principal amount of Securities have given or concurred in any request, demand, authorization, direction, notice, consent, waiver, or other Act hereunder, Securities owned by the Company or any other obligor upon the Securities or any Affiliate of the Company or such other obligor shall be disregarded and deemed not to be outstanding, except that, in determining whether the Trustee shall be protected in relying upon any such request, demand, authorization, direction, notice, consent, waiver or other Act, only Securities which a Responsible Officer of the Trustee actually knows to be so owned shall be so disregarded. Subject to the foregoing, only Securities outstanding at the time of such determination shall be considered in any such determination.

If a Security is replaced pursuant to Section 2.7, the replaced Security ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Security is held by a bona fide purchaser unaware that such Security has been replaced.

If the Paying Agent holds, in accordance with the terms of this Indenture, prior to 10:00 a.m., New York City time, on a Redemption Date, a Purchase Date, a Fundamental Change Purchase Date or Stated Maturity, as the case may be, cash or securities, if permitted hereunder, sufficient to pay Securities payable on that date, then on such Redemption Date, Purchase Date, Fundamental Change Purchase Date or Stated Maturity, as the case may be, such Securities shall cease to be outstanding and interest and Additional Interest, if any, on such Securities shall cease to accrue.

If a Security is converted in accordance with ARTICLE XII, then from and after the time of conversion on the date of conversion, such Security shall cease to be outstanding and interest and Additional Interest, if any, on such Security shall cease to accrue.

Section 2.9 Temporary Securities.

Pending the preparation of definitive Securities, the Company may execute, and upon Company Order, the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other

II-B-20

variations as the Officers executing such Securities may determine, as conclusively evidenced by their execution of such Securities.

If temporary Securities are issued, the Company shall cause definitive Securities to be prepared without unreasonable delay. After the preparation of definitive Securities, the temporary Securities shall be exchangeable for definitive Securities upon surrender of the temporary Securities at the office or agency of the Company designated for such purpose pursuant to Section 2.3, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Securities of authorized denominations. Until so exchanged the temporary Securities shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as definitive Securities.

Section 2.10 Cancellation.

All Securities surrendered for payment, repurchase by the Company pursuant to ARTICLE IV or ARTICLE V, conversion, redemption or registration of transfer or exchange shall, if surrendered to any person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it or, if surrendered to the Trustee, shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be promptly cancelled by the Trustee. The Company may not issue new Securities to replace Securities that it has paid or delivered to the Trustee for cancellation or that any Holder has converted pursuant to ARTICLE XII. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section 2.10, except as expressly permitted by this Indenture. All cancelled Securities held by the Trustee shall be disposed of by the Trustee in accordance with the Trustee’s customary procedure.

Section 2.11 Persons Deemed Owners.

Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of, Redemption Price, Purchase Price or Fundamental Change Purchase Price, and interest, Contingent Interest and Additional Interest, if any, on, the Security, for the purpose of receiving cash or Applicable Stock upon conversion and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary.

Section 2.12 Additional Transfer and Exchange Requirements.

(a) Transfer and Exchange of Global Securities.

(i) Certificated Securities shall be issued in exchange for interests in the Global Securities only if (x) the Depositary notifies the Company that it is unwilling or unable to continue as Depositary for the Global Securities, (y) the Depositary ceases to be a “clearing agency” registered under the Exchange Act, if so required by applicable law or regulation and a successor Depositary is not appointed by the Company within 90 calendar days or (z) an Event of Default has occurred and is continuing. In any such case, the Company shall execute, and the Trustee shall, upon receipt of a Company Order (which the Company agrees to deliver promptly), authenticate and deliver Certificated Securities in an aggregate principal amount equal to the principal amount of such Global Securities in exchange therefor. Only Restricted Certificated Securities shall be issued in exchange for beneficial interests in Restricted Global Securities, and only Unrestricted Certificated Securities shall be issued in exchange for beneficial interests in Unrestricted Global Securities. Certificated Securities issued in exchange for beneficial interests in Global Securities shall be registered in such names and shall be in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. The Trustee shall deliver or cause to be delivered such Certificated Securities to the Persons in whose name such Securities are so registered. Such exchange shall be effected in accordance with the Applicable Procedures

II-B-21

(ii) Notwithstanding any other provisions of this Indenture other than the provisions set forth in Section 2.12(a)(i), a Global 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.

(b) Transfer and Exchange of Certificated Securities. In the event that Certificated Securities are issued in exchange for beneficial interests in Global Securities in accordance with Section 2.12(a)(i), and, on or after such event, Certificated Securities are presented by a Holder to the Registrar with a request:

(x) to register the transfer of the Certificated Securities to a person who will take delivery thereof in the form of Certificated Securities only; or

(y) to exchange such Certificated Securities for an equal principal amount of Certificated Securities of other authorized denominations,

such Registrar shall register the transfer or make the exchange as requested; provided, however, that the Certificated Securities presented or surrendered for register of transfer or exchange:

(i) shall be duly endorsed or accompanied by a written instrument of transfer in accordance with the proviso in the first paragraph of Section 2.6(a); and

(ii) in the case of a Restricted Certificated Security, such request shall be accompanied by the following additional information and documents, as applicable:

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

(B) if such Restricted Certificated Security is being transferred to a person the Holder reasonably believes is a QIB in compliance with Rule 144A, pursuant to the exemption from the registration requirements of the Securities Act provided by Rule 144 (if available) or pursuant to an effective registration statement under the Securities Act, a certification to that effect from such Holder (in substantially the form set forth in the Transfer Certificate); or

(C) if such Restricted Certificated Security is being transferred pursuant to an exemption from the registration requirements of the Securities Act to an Institutional Accredited Investor (other than to a QIB in accordance with Rule 144A), that, prior to such transfer, furnishes to the Trustee a certificate containing certain representations and warranties by such Institutional Accredited Investor (in substantially the form set forth in Exhibit B), an Opinion of Counsel if required by the Company or the Trustee and a certification to that effect from the Holder (in substantially the form set forth in the Transfer Certificate).

(c) Transfer of a Beneficial Interest in a Restricted Global Security for a Beneficial Interest in an Unrestricted Global Security. Any person having a beneficial interest in a Restricted Global Security may upon request, subject to the Applicable Procedures, transfer such beneficial interest to a person who is required or permitted to take delivery thereof in the form of an Unrestricted Global Security. Upon receipt by the Trustee of written instructions, or such other form of instructions as is customary for the Depositary, from the Depositary or its nominee on behalf of any person having a beneficial interest in a Restricted Global Security and the following additional information and documents in such form as is customary for the Depositary from the Depositary or its nominee on behalf of the person having such beneficial interest in the Restricted Global Security (all of which may be submitted by facsimile or electronically):

II-B-22

(i) if such beneficial interest is being transferred pursuant to an effective registration statement under the Securities Act, a certification to that effect from the Holder (in substantially the form set forth in the Transfer Certificate); or

(ii) if such beneficial interest is being transferred pursuant to the exemption from the registration requirements of the Securities Act provided by Rule 144, a certification to that effect from the Holder (in substantially the form set forth in the Transfer Certificate),

the Trustee, as the Registrar, shall reduce or cause to be reduced the aggregate principal amount of the Restricted Global Security by the appropriate principal amount and shall increase or cause to be increased the aggregate principal amount of the Unrestricted Global Security by a like principal amount. Such transfer shall otherwise be effected in accordance with the Applicable Procedures. If no Unrestricted Global Security is then outstanding, the Company shall execute and the Trustee shall, upon receipt of a Company Order (which the Company agrees to deliver promptly), authenticate and deliver an Unrestricted Global Security.

(d) Transfers of Certificated Securities for Beneficial Interests in Global Securities. In the event that Certificated Securities are issued in exchange for beneficial interests in Global Securities and, thereafter, the events or conditions specified in Section 2.12(a)(i) which required such exchange shall cease to exist, the Company shall mail notice to the Trustee and to the Holders stating that Holders may exchange Certificated Securities for interests in Global Securities by complying with the procedures set forth in this Indenture and briefly describing such procedures and the events or circumstances requiring that such notice be given. Thereafter, if Certificated Securities are presented by a Holder to a Registrar with a request:

(x) to register the transfer of such Certificated Securities to a person who will take delivery thereof in the form of a beneficial interest in a Global Security, which request shall specify whether such Global Security will be a Restricted Global Security or an Unrestricted Global Security, or

(y) to exchange such Certificated Securities for an equal principal amount of beneficial interests in a Global Security, which beneficial interests shall be owned by the Holder transferring such Certificated Securities (provided that in the case of such an exchange, Restricted Certificated Securities may be exchanged only for Restricted Global Securities and Unrestricted Certificated Securities may be exchanged only for Unrestricted Global Securities), the Registrar shall register the transfer or make the exchange as requested by canceling such Certificated Security and causing, or directing the Registrar to cause, the aggregate principal amount of the applicable Global Security to be increased accordingly and, if no such Global Security is then outstanding, the Company shall issue and the Trustee shall, upon receipt of a Company Order (which the Company agrees to deliver promptly) authenticate and deliver a new Global Security;

provided, however, that the Certificated Securities presented or surrendered for registration of transfer or exchange:

(1) shall be duly endorsed or accompanied by a written instrument of transfer in accordance with the proviso in the first paragraph of Section 2.6(a);

(2) in the case of a Restricted Certificated Security to be transferred for a beneficial interest in an Unrestricted Global Security, such request shall be accompanied by the following additional information and documents, as applicable:

(i) if such Restricted Certificated Security is being transferred pursuant to an effective registration statement under the Securities Act, a certification to that effect from such Holder (in substantially the form set forth in the Transfer Certificate); or

(ii) if such Restricted Certificated Security is being transferred pursuant to the exemption from the registration requirements of the Securities Act provided by Rule 144, a certification to that effect from such Holder (in substantially the form set forth in the Transfer Certificate);

II-B-23

(3) in the case of a Restricted Certificated Security to be transferred or exchanged for a beneficial interest in a Restricted Global Security, such request shall be accompanied by a certification from such Holder (in substantially the form set forth in the Transfer Certificate) to the effect that such Restricted Certificated Security is being transferred to a person the Holder reasonably believes is a QIB (which, in the case of an exchange, shall be such Holder) in compliance with Rule 144A or, in the case of a transfer to an Institutional Accredited Investor (other than to a QIB in accordance with Rule 144A), by a certificate containing certain representations and warranties by such Institutional Accredited Investor (in substantially the form set forth in Exhibit B), an Opinion of Counsel if required by the Company or the Trustee and a certification to that effect from the Holder (in substantially the form set forth in the Transfer Certificate); and

(4) in the case of an Unrestricted Certificated Security to be transferred or exchanged for a beneficial interest in an Unrestricted Global Security, such request need not be accompanied by any additional information or documents.

(e) Legends.

(1) Except as permitted by the following paragraphs (2), (3) and (4), each Global Security and Certificated Security (and all Securities issued in exchange therefor or upon registration of transfer or replacement thereof) shall bear a legend in substantially the form called for by footnote 2 to Exhibit A and footnote 1 to Exhibit C attached hereto (each a “Transfer Restricted Security”), for so long as it is required by this Indenture to bear such legend. Each Transfer Restricted Security shall have attached thereto a certificate (a “Transfer Certificate”) in substantially the form called for by footnote 4 to Exhibit A attached hereto.

(2) Upon any sale or transfer of a Transfer Restricted Security (x) pursuant to Rule 144 or (y) pursuant to an effective registration statement under the Securities Act:

(i) in the case of any Restricted Certificated Security, any Registrar shall permit the Holder thereof to exchange such Restricted Certificated Security for an Unrestricted Certificated Security, or (under the circumstances described in Section 2.12(d)) to transfer such Restricted Certificated Security to a transferee who shall take such Security in the form of a beneficial interest in an Unrestricted Global Security, and in each case shall rescind any restriction on the transfer of such Security; and

(ii) in the case of any beneficial interest in a Restricted Global Security, the Trustee shall permit the beneficial owner thereof to transfer such beneficial interest to a transferee who shall take such interest in the form of a beneficial interest in an Unrestricted Global Security and shall rescind any restriction on transfer of such beneficial interest; provided, that such Unrestricted Global Security shall continue to be subject to the provisions of Section 2.12(a)(ii).

(3) Upon the expiration of the holding period pursuant to Rule 144(k) of the Securities Act, the Company shall remove any restriction of transfer on such Security, and the Company shall execute, and the Trustee shall authenticate and deliver Securities that do not bear such legend and that do not have a Transfer Certificate attached thereto.

(4) Until the expiration of the holding period applicable to sales of the Securities under Rule 144(k) of the Securities Act or a transfer of the Securities pursuant to Rule 144 or pursuant to an effective registration statement under the Securities Act, the Applicable Stock issued upon conversion of the Securities shall bear the legend in substantially the form called for by Exhibit C attached hereto.

II-B-24

(f) Transfers to the Company. Nothing contained in this Indenture or in the Securities shall prohibit the sale or other transfer of any Securities (including beneficial interests in Global Securities) to the Company or any of its Subsidiaries. The Company shall ensure that if any such Securities shall be reissued, such reissuance shall comply with applicable law and any Securities reissued as Transfer Restricted Securities shall be assigned a different “CUSIP” number than any other Securities.

(g) Amendments to Rule 144(k). Notwithstanding any other provision in this Indenture, if Rule 144(k) as promulgated under the Securities Act is amended to shorten the two-year period under Rule 144(k), then the references to “two years” in the restrictive legend of each Transfer Restricted Security shall be deemed to refer to such shorter period, from and after receipt by the Trustee of the documents described in Section 2.12(d)(2) from the Company or from a Holder of a Transfer Restricted Security; provided that, Transfer Restricted Security shall not be deemed to refer to such shorter period if to do so would be prohibited by, or would otherwise cause a violation of, the U.S. federal securities laws applicable at the time. As soon as practicable after a Responsible Officer of the Company receives notice of the effectiveness of any such amendment to shorten the two-year period under Rule 144(k), unless causing the Transfer Restricted Securities to refer to such shorter period would otherwise be prohibited by, or would otherwise cause a violation of, the U.S. federal securities laws applicable at the time, the Company will provide to the Trustee the documents described in Section 2.12(d)(2) respecting the effectiveness of such amendment.

Section 2.13 CUSIP Numbers.

The Company may issue the Securities with 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 shall promptly notify the Trustee of any change in the CUSIP numbers.

ARTICLE III

REDEMPTION OF NOTES

Section 3.1 The Company’s Right to Redeem; Notice to Trustee.

Subject to the terms and conditions of this ARTICLE III, the Company may, at its option, redeem for cash all or a portion of the Notes at any time:

(i) during the period commencing on February 4, 2009 to and including January 31, 2010, at a Redemption Price equal to 100.571% of the Accreted Principal Amount of the Notes plus accrued and unpaid interest, Contingent Interest and Additional interest, if any, to, but not including, the Redemption Date;

(ii) during the period commencing on February 1, 2010 to and including January 31, 2011, at a Redemption Price equal to 100.286% of the Accreted Principal Amount of the Notes plus accrued and unpaid interest, Contingent Interest and Additional Interest, if any, to, but not including, the Redemption Date; and

(iii) beginning on February 1, 2011, at a Redemption Price equal to 100% of the Accreted Principal Amount of the Notes plus accrued and unpaid interest, Contingent Interest and Additional Interest, if any, to, but not including, the Redemption Date.

In the event that the Company elects to redeem Notes on a date that is after any Regular Record Date but on or before the corresponding Interest Payment Date, the Company shall be required to pay any accrued

II-B-25

and unpaid interest, Contingent Interest and Additional Interest, if any, to the holder of the redeemed Note and not the Holder on the corresponding Regular Record Date.

If the Company elects to redeem Notes, it shall notify the Trustee in writing of the Redemption Date, the Principal Amount at Issuance of Notes to be redeemed and the Redemption Price. The Company shall give this notice to the Trustee by a Company Order at least 30 calendar days before the Redemption Date (unless a shorter notice shall be satisfactory to the Trustee).

Section 3.2 Selection of Notes to Be Redeemed.

If fewer than all of the outstanding Notes are to be redeemed, unless the procedures of the Depositary provide otherwise, the Trustee shall select the Notes to be redeemed by lot or on a pro rata basis or by another method the Trustee considers fair and appropriate. The Trustee shall make the selection within five Business Days after it receives the notice provided for in Section 3.1 from outstanding Notes not previously called for redemption.

Notes and portions of Notes that the Trustee selects shall be in Principal Amounts at Issuance of $1,000 or an integral multiple thereof. Provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption. The Trustee shall notify the Company promptly of the Notes or portions of the Notes to be redeemed.

Notes and portions of Notes that are to be redeemed are convertible by the Holder until 5:00 p.m., New York City time, on the second Business Day immediately preceding the Redemption Date. If any Note selected for partial redemption is converted in part before termination of the conversion right with respect to the portion of the Note so selected, the converted portion of such Note shall be deemed (so far as may be) to be the portion selected for redemption and the Trustee shall select additional Notes to be redeemed in the manner provided in the first paragraph of this Section 3.2 in an amount equal to the Notes that would have been redeemed but for their conversion prior to the termination of their conversion right. Notes which have been converted during a selection of Notes to be redeemed may be treated by the Trustee as outstanding for the purpose of such selection.

Section 3.3 Notice of Redemption.

The notice of redemption shall identify the Securities to be redeemed and shall state:

(a) the Redemption Date;

(b) the Redemption Price;

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

(e) that Notes called for redemption may be converted at any time prior to 5:00 p.m., New York City time, on the second Business Day preceding the Redemption Date;

(f) that Holders who want to convert their Notes must satisfy the requirements set forth in ARTICLE XII;

(g) that Notes called for redemption must be surrendered to the Paying Agent to collect the Redemption Price;

II-B-26

(h) if fewer than all of the outstanding Notes are to be redeemed, the serial numbers, if any, and Principal Amounts at Issuance of the particular Notes to be redeemed;

(i) that, unless the Company defaults in making payment of such Redemption Price, interest, Contingent Interest and Additional Interest, if any, on Notes called for redemption shall cease to accrue on and after the Redemption Date;

(j) the CUSIP number(s) of the Securities; and

(k) any other information the Company wants to present.

At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at the Company’s expense; provided, however, that the Company makes such request at least five Business Days (unless a shorter period shall be satisfactory to the Trustee) prior to the date by which such notice of redemption must be given to Holders in accordance with this Section 3.3; provided, further, that the text of the notice of redemption shall be prepared by the Company.

Section 3.4 Effect of Notice of Redemption.

Once notice of redemption is given, Notes called for redemption become due and payable on the Redemption Date and at the Redemption Price, except for Notes which are converted in accordance with the terms of this Indenture. Upon surrender to the Paying Agent, such Notes shall be paid at the Redemption Price.

Section 3.5 Deposit of Redemption Price.

Prior to 10:00 a.m., New York City time, on the applicable Redemption Date, the Company shall irrevocably deposit with the Paying Agent an amount of cash (in immediately available funds if deposited on the Redemption Date) sufficient to pay the aggregate Redemption Price of all Notes or portions thereof which are to be redeemed as of such Redemption Date other than Notes or portions of Notes called for redemption which on or prior thereto have been delivered by the Company to the Trustee for cancellation or have been converted.

If the Paying Agent holds, in accordance with the terms hereof, at 10:00 a.m., New York City time, on the applicable Redemption Date, cash sufficient to pay the Redemption Price of any Notes for which notice of redemption is given, then, on such Redemption Date, such Notes shall cease to be outstanding and interest, Contingent Interest and Additional Interest, if any, on such Notes shall cease to accrue, whether or not such Notes are delivered to the Paying Agent, and the rights of the Holders in respect thereof shall terminate (other than the right to receive the Redemption Price upon delivery of such Notes).

Section 3.6 Notes Redeemed in Part.

Any Certificated Security which is to be redeemed only in part shall be surrendered at the office of the Paying Agent and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security, without charge, a new Security or Securities, of any authorized denomination as requested by such Holder in aggregate principal amount equal to the unredeemed portion of the Security surrendered.

Section 3.7 Repayment to the Company.

To the extent that the aggregate amount of cash deposited by the Company pursuant to Section 3.5 exceeds the aggregate Redemption Price of the Notes or portions thereof which the Company is redeeming as of the Redemption Date, then, promptly after the Redemption Date, the Paying Agent shall return any such excess to the Company together with interest, if any, thereon.

Section 3.8 No Sinking Fund.

The Notes shall not have a sinking fund.

(b) No later than 22 Business Days prior to each Purchase Date, the Company shall mail a written notice of the purchase right by first class mail to the Trustee (and the Paying Agent if the Trustee is not then acting as a Paying Agent) and to each Holder at its address shown in the Register of the Registrar, and to beneficial owners as required by applicable law. The notice shall include a form of Purchase Notice to be completed by the Holder and shall briefly state, as applicable:

II-B-28

(xiii) the CUSIP number(s) of the Notes.

At the Company’s request, the Trustee shall give the notice of purchase right in the Company’s name and at the Company’s expense; provided, however, that the Company makes such request at least five Business Days (unless a shorter period shall be satisfactory to the Trustee) prior to the date by which such notice of purchase right must be given to the Holders in accordance with this Section 4.1(b); provided, further, that the text of the notice of purchase right shall be prepared by the Company.

If any of the Notes is in the form of a Global Security, then the Company shall modify such notice to the extent necessary to accord with the procedures of the Depositary applicable to the purchase of Global Securities.

Simultaneously with delivering the written notice pursuant to this Section 4.1(b), the Company shall make a Public Notice containing all information specified in such written notice.

(c) A Holder may exercise its rights specified in clause (a) of this Section 4.1 upon delivery of a written notice (which shall be in substantially the form included on the reverse side of the Securities entitled “Option of Holder to Elect Purchase” hereto and which may be delivered by letter, overnight courier, hand delivery, facsimile transmission or in any other written form and, in the case of Global Securities, may be delivered electronically or by other means in accordance with the Depositary’s customary procedures) of the exercise of such rights (a “Purchase Notice”) to the Paying Agent at any time from the opening of business on the date that is 22 Business Days prior to the relevant Purchase Date until the close of business on the second Business Day prior to such Purchase Date.

The Purchase Notice delivered by a Holder shall state (i) the relevant Purchase Date, (ii) if certificated Securities, the serial number or numbers of the Note or Notes which the Holder shall deliver to be purchased (if not certificated, the notice must comply with Applicable Procedures), (iii) the portion of the Principal Amount at Issuance of the Note which the Holder shall deliver to be purchased, which portion must be $1,000 or an integral multiple thereof, and (iv) that such Note shall be purchased pursuant to the terms and conditions specified in the Securities and this Indenture.

Delivery of a Note to the Paying Agent by book-entry transfer or physical delivery prior to, on or after the applicable Purchase Date (together with all necessary endorsements) at the offices of the Paying Agent is a condition to receipt by the Holder of the Purchase Price therefor; provided, however, that such Purchase Price shall be so paid pursuant to this Section 4.1 only if the Note so delivered to the Paying Agent shall conform in all respects to the description thereof in the related Purchase Notice, as determined by the Company.

The Company shall purchase from the Holder thereof, pursuant to this Section 4.1, a portion of a Note if the Principal Amount at Issuance of such portion is $1,000 or an integral multiple thereof.

(b) A Purchase Notice may be withdrawn by means of a written notice (which may be delivered by letter, overnight courier, hand delivery, facsimile transmission or in any other written form and, in the case of Global Securities, may be delivered electronically or by other means in accordance with the Depositary’s customary procedures) of withdrawal delivered by the Holder to the Paying Agent at any time prior to the close of business on the Business Day immediately preceding the Purchase Date, specifying (a) the Principal Amount of the Note or portion thereof (which must be a Principal Amount at Issuance of $1,000 or an integral multiple thereof) with respect to which such notice of withdrawal is being submitted, (b) if certificated Securities have been issued, the serial numbers of the withdrawn Notes, or if not certificated, such notice must comply with Applicable Procedures, and (c) the Principal Amount at Issuance, if any, which remains subject to the Purchase Notice.

The Company shall make a Public Notice of the aggregate Accreted Principal Amount of Notes purchased on the applicable Purchase Date on such date or as soon as practicable thereafter.

Section 4.4 Certificated Securities Purchased in Part.

(viii) that the Notes must be surrendered to the Paying Agent to collect payment;

(ix) that the Fundamental Change Purchase Price for any Note as to which a Fundamental Change Purchase Notice has been duly given and not withdrawn shall be paid promptly following the later of the Fundamental Change Purchase Date and the time of surrender of such Note as described in Section 5.1(b)(viii);

(xiv) the CUSIP number(s) of the Notes.

At the Company’s request, the Trustee shall give the notice of purchase right in the Company’s name and at the Company’s expense; provided, however, that the Company makes such request at least five Business Days (unless a shorter period shall be satisfactory to the Trustee) prior to the date by which such notice of purchase right must be given to the Holders in accordance with this Section 5.1(b); provided, further, that the text of the notice of purchase right shall be prepared by the Company.

Section 6.3 Compliance Certificate.

The Company shall deliver to the Trustee within 120 calendar days after the end of each fiscal year of the Company an Officers’ Certificate, stating whether or not to the knowledge of the signers thereof, the Company is in compliance with all conditions and covenants under this Indenture.

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

Upon the request of a Holder or any beneficial owner of Notes or holder or beneficial owner of Common Stock issued upon conversion thereof, the Company and the Guarantors shall promptly furnish or cause to be furnished the information required pursuant to Rule 144A(d)(4) under the Securities Act to such Holder or any beneficial owner of Securities or holder or beneficial owner of Common Stock, or to a prospective purchaser of any such security designated by any such holder, as the case may be, to the extent required to permit compliance by such Holder or holder with Rule 144A under the Securities Act in connection with the resale of any such security.

Section 8.2 Acceleration.

If an Event of Default (other than an Event of Default specified in Section 8.1(j) or Section 8.1(k) with respect to the Company) occurs and is continuing (including an Event of Default specified in Section 8.1(j) or Section 8.1(k) with respect to one or more Guarantors or Significant Subsidiaries), the Trustee by notice to the Company, or the Holders of at least 25% in aggregate principal amount of the Notes at the time outstanding by notice to the Company and the Trustee, may declare the Accreted Principal Amount plus accrued and unpaid interest, Contingent Interest and Additional Interest, if any, on all the Notes to be immediately due and payable. Upon such a declaration, such accelerated amount shall be due and payable immediately.

If an Event of Default specified in Section 8.1(j) or Section 8.1(k) occurs with respect to the Company and is continuing, the Accreted Principal Amount plus accrued and unpaid interest, Contingent Interest and Additional Interest, if any, on all the Notes shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders.

The Holders of a majority in aggregate principal amount of the Notes at the time outstanding, by notice to the Trustee (and without notice to any other Holder) may rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default have been cured or waived except nonpayment of the Accreted Principal Amount plus accrued and unpaid interest, Contingent Interest and Additional Interest, if any, that have become due solely as a result of acceleration and if all amounts due to the Trustee under Section 9.7 have been paid.

If an Event of Default occurs and is continuing, the Trustee may, but shall not be obligated to, pursue any available remedy to collect the payment of the principal plus accrued and unpaid interest, Contingent Interest and Additional Interest, if any, on the Notes or to enforce the performance of any provision of the Notes or this Indenture.

The Trustee may maintain a proceeding even if the Trustee does not possess any of the Notes or does not produce any of the Notes 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.

Section 8.4 Waiver of Past Defaults.

Subject to Section 8.7 and Section 11.2, the Holders of a majority in aggregate principal amount of the Notes at the time outstanding, by notice to the Trustee (and without notice to any other Holder), may waive an existing Default and its consequences except:

(c) a Default in respect of any provision of this Indenture or the Notes, which, under Section 11.2, cannot be amended or modified without the consent of each Holder affected thereby.

When a Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or impair any consequent right.

(b) to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay the Trustee any amount due 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.

The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee; provided that the Trustee must comply with Section 9.10 and Section 9.11.

Section 9.5 Notice of Defaults.

If a Default occurs and if it is known to the Trustee, the Trustee shall give to each Holder notice of the Default within 90 calendar days after it occurs or, if later, within 15 calendar days after it is known to the Trustee, unless such Default shall have been cured or waived before the giving of such notice. Notwithstanding the preceding sentence, except in the case of a Default described in Section 8.1(a), Section 8.1(b), Section 8.1(d) or Section 8.1(f), the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interest of the Holders. The preceding sentence shall be in lieu of the proviso to Section 315(b) of the TIA and such proviso is hereby expressly excluded from this Indenture, as permitted by the TIA.

Section 9.6 Reports by Trustee to Holders.

Within 60 days after each May 15 beginning with the May 15 following the date of this Indenture, the Trustee shall mail to each Holder a brief report dated as of such May 15 that complies with TIA Section 313(a), if required by such Section 313(a). The Trustee also shall comply with TIA Section
313(b).

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

Section 9.7 Compensation and Indemnity.

The Company agrees to:

(a) pay to the Trustee from time to time such compensation as the Company and the Trustee shall from time to time agree in writing for all services rendered by it hereunder (which compensation shall not be limited (to the extent permitted by law) by any provision of law in regard to the compensation of a trustee of an express trust);

(b) reimburse the Trustee upon its request for all expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the compensation and the reasonable expenses, advances and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be attributable to its own negligence or willful misconduct; and

II-B-45

expenses, and taxes (other than taxes based upon, measured by or determined by the income of the Trustee)) incurred without the Trustee’s negligent action, negligent failure to act or willful misconduct, arising out of or in connection with the acceptance or administration of this trust, including the costs and expenses of defending itself against any claim (whether asserted by the Company or any Holder or any other person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, or in connection with enforcing the provisions of this Section 9.7.

With regard to its indemnification rights under Section 9.7(c) where the Company has assumed the defense in any action or proceeding, the Trustee shall have the right to employ separate counsel in any such action or proceeding and participate in the investigation and defense thereof, and the Company shall pay the reasonable fees and expenses of such separate counsel; provided, however, that the Trustee may only employ separate counsel at the expense of the Company if in the judgment of the Trustee (i) a conflict of interest exists by reason of common representation or (ii) there are legal defenses available to the Trustee that are different from or are in addition to those available to the Company or if all parties commonly represented do not agree as to the action (or inaction) of counsel.

The Company’s payment obligations pursuant to this Section 9.7 shall survive the discharge of this Indenture and the resignation or removal of the Trustee. When the Trustee incurs expenses after the occurrence of a Default specified in Section 8.1(j) or Section 8.1(k), the expenses including the reasonable charges and expenses of its counsel, are intended to constitute expenses of administration under any Bankruptcy Law.

Section 9.8 Replacement of Trustee.

The Trustee may resign by so notifying the Company; provided, however, that no such resignation shall be effective until a successor Trustee has accepted its appointment pursuant to this Section 9.8. The Holders of a majority in aggregate principal amount of the Securities at the time outstanding may remove the Trustee by so notifying the Trustee and the Company. The Company shall remove the Trustee if:

(a) the Trustee fails to comply with Section 9.10;

(b) the Trustee is adjudged bankrupt or insolvent;

(d) the Trustee otherwise becomes incapable of acting.

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint, by resolution of its Board of Directors, a successor Trustee.

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company satisfactory in form and substance to the retiring Trustee and the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, upon payment of all the retiring Trustee’s fees and expenses then due and payable and subject to the lien provided for in Section 9.7.

If a successor Trustee does not take office within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of a majority in aggregate principal amount of the

II-B-46

Securities at the time outstanding may petition at the expense of the Company any court of competent jurisdiction at the expense of the Company for the appointment of a successor Trustee.

If the Trustee fails to comply with Section 9.10, any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

Section 9.9 Successor Trustee by Merger.

If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation, the resulting, surviving or transferee corporation without any further act shall be the successor Trustee.

Section 9.10 Eligibility; Disqualification.

The Trustee and any successor Trustee shall at all times satisfy the requirements of TIA Sections 310(a)(1) and 310(b). The Trustee (or its parent holding company) shall have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition. Nothing contained herein shall prevent the Trustee from filing with the SEC the application referred to in the penultimate paragraph of TIA Section 310(b). If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section 9.10, it shall resign immediately in the manner and with the effect hereinafter specified in this Article.

Section 9.11 Preferential Collection of Claims Against Company.

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

Any notice so given shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice.

Notes called for redemption may be converted at any time on and after the date that the Company gives notice to the Holders of such right until 5:00 p.m., New York city time, on the second Business Day preceding the corresponding Redemption Date.

With respect to any conversion of a Note during a Registration Default Period following satisfaction of any of the conditions to conversion described in the Indenture (and during the prescribed time periods in respect thereof), a Holder shall be entitled, subject to Section 12.13, to 103% of the number of shares of Common Stock that the Holder would have otherwise been entitled to upon conversion in respect of the portion of the Conversion Obligation that the Company settles in Common Stock.

(b) (i) In the event that:

(A) the Company distributes to all holders of the Common Stock rights or warrants entitling them (for a period expiring within 60 days of the Record Date for such distribution) to subscribe for or purchase Common Stock at a price per share of Common Stock less than the Closing Sale Price of the Common Stock on the Business Day immediately preceding the announcement of such distribution;

(B) the Company distributes to all holders of its Common Stock cash or other assets, debt securities or rights or warrants to purchase its securities, including the declaration of any cash dividends, payable quarterly or otherwise, where the Fair Market Value (as determined by the Board of Directors) of such distribution per share of Common Stock exceeds 10% of the Closing Sale Price of the Common Stock on the Business Day immediately preceding the date of declaration of such distribution; or

then, in each case, the Notes may be surrendered for conversion at any time on and after the date that the Company gives notice (including by making a Public Notice) to the Holders of such right, which shall be, in the case of (A) or (B), not less than 20 Business Days prior to the Ex-Dividend Time for such distribution, or, in the case of (C), within 20 Business Days after the occurrence of the Fundamental Change, until 5:00 p.m., New York City time, on the earlier of the Business Day immediately preceding the Ex-Dividend Time and the date the Company announces that such distribution shall not take place in the case of (A) or (B), or within 20 Business Days of the Company’s delivery of the notice of the Fundamental Change in the case of (C); provided, however, that in the case of (A) or (B), a Holder of Notes may not surrender Notes for conversion if the Holder shall otherwise participate in such distribution without conversion.

II-B-51

(ii) In addition, in the event that the Company consolidates or merges with or into another Person, or is a party to a binding share exchange pursuant to which the Common Stock would be converted into cash, securities or other property as set forth in Section 12.4, then the Notes may be surrendered for conversion at any time from and after the date which is 15 calendar days prior to the date the Company announces by Public Notice as the anticipated effective time of such transaction until 15 calendar days after the actual date of such transaction.

(c) Notwithstanding the foregoing, a Note in respect of which a Holder has delivered a Purchase Notice or a Fundamental Change Purchase Notice, as the case may be, exercising such Holder’s right to require the Company to repurchase such Note may be converted only if such Purchase Notice or Fundamental Change Purchase Notice is withdrawn in accordance with Section 4.2(b) or Section 5.2(b) prior to 5:00 p.m., New York City time, on the Business Day immediately preceding such Purchase Date or Fundamental Change Purchase Date.

Section 12.2 Conversion Procedures; Conversion Rate; Fractional Shares.

(a) Subject to Section 12.13, each Note shall be convertible at the office of the Conversion Agent into fully paid and nonassessable shares of Common Stock (calculated to the nearest 1/10,000th of a share).

The Conversion Agent shall notify the Company when it receives a Conversion Notice. Pursuant to Section 12.13, the Company shall determine the number of shares of Common Stock and/or the amount of cash, if any, that the Holder that submitted the Conversion Notice is entitled to receive upon surrender of the Notes covered by that Conversion Notice. If the Company elects to settle in Common Stock only, a certificate for the number of full shares of Common Stock into which the Notes are converted (and cash in lieu of fractional shares) shall be delivered by the Company to such Holder, assuming all of the other requirements have been satisfied by such Holder, as soon as practicable after the Company issues its notification of its chosen method of settlement in accordance with Section 12.13. If the Company elects to settle in cash or a combination of cash and Common Stock, the cash and, if applicable, a certificate for the number of full shares of Common Stock into which the Notes are converted (and cash in lieu of fractional shares) shall be paid and delivered to such Holder, assuming all of the other requirements have been satisfied by such Holder, in accordance with Section 12.13. Notwithstanding the foregoing, the Company shall not be required to deliver certificates for Common Stock while the stock transfer books for such stock or the security register are duly closed for any purpose, but certificates for Common Stock shall be issued and delivered as soon as practicable after the opening of such books or security register.

Except as described in Section 12.9, the Company will not make any payment in cash or Common Stock or other adjustment for accrued and unpaid interest, Contingent Interest or Additional Interest on any Notes when they are converted. The Company’s delivery to the Holder of the full number of shares of Common Stock into which the Note is convertible (or, at the Company’s option, cash, or a combination of cash and Common Stock, in lieu thereof as provided in Section 12.13), together with any cash payment for such Holder’s fractional shares, shall be deemed to satisfy the Company’s obligation to pay the Accreted Principal Amount of the Note and to satisfy its obligation to pay accrued and unpaid interest, Contingent Interest and Additional Interest, if any through the conversion date. As a result, accrued interest, Contingent Interest and Additional Interest are deemed paid in full rather than cancelled, extinguished or forfeited. Notwithstanding the foregoing, accrued interest, Contingent Interest and Additional Interest, if any, will be payable upon any conversion of Notes made concurrently with or after acceleration of the Notes following an Event of Default.

If a Holder has exercised its right to require the Company to repurchase its Notes pursuant to ARTICLE IV or ARTICLE V, such Holder’s conversion rights on the Notes so subject to repurchase shall expire at 5:00 p.m., New York City time, on the Business Day immediately preceding the Purchase Date or Fundamental Change Purchase Date, as the case may be. Notwithstanding the foregoing, a Note in respect of which a Holder has delivered a Purchase Notice or a Fundamental Change Purchase Notice, as the case may be, exercising such Holder’s right to require the Company to repurchase such Note may be converted only if such Purchase Notice or Fundamental Change Purchase Notice is withdrawn in accordance with Section 4.2(b) or Section 5.2(b) prior to
5:00 p.m., New York City time, on the Business Day immediately preceding such Purchase Date or Fundamental Change Purchase Date.

II-B-52

(b) Before any Holder shall be entitled to convert any Notes into Common Stock, such Holder shall, in the case of Global Securities, comply with the Applicable Procedures of the Depositary in effect at that time, and in the case of Certificated Securities, surrender such Securities, duly endorsed to the Company or in blank, at the office of the Conversion Agent, and shall give written notice to the Company at said office or place in the form of the Conversion Notice attached to the Note (the “Conversion Notice”) that such Holder elects to convert the same and shall state in writing therein the Principal Amount at Issuance of Notes to be converted (in whole or in part so long as the Principal Amount at Issuance to be converted is in multiples of $1,000) and the name or names (with addresses) in which such Holder wishes the certificate or certificates for Common Stock to be issued.

Before any such conversion, a Holder also shall pay all funds required, if any, relating to interest, Contingent Interest or Additional Interest, if any, on the Notes, as provided in Section 12.9, and all taxes or duties, if any, as provided in Section 12.8.

If more than one Note shall be surrendered for conversion at one time by the same Holder, the number of full shares of Common Stock that shall be deliverable upon conversion shall be computed on the basis of the aggregate Principal Amount at Issuance of the Notes (or specified portions thereof to the extent permitted thereby) so surrendered.

If shares of Common Stock to be issued upon conversion of a Restricted Security are to be issued in the name of a Person other than the Holder of such Restricted Security, such Holder shall deliver to the Conversion Agent a certification in substantially the form set forth in a Transfer Certificate dated the date of surrender of such Restricted Security and signed by such Holder, as to compliance with the restrictions on transfer applicable to such Restricted Security. The Company shall not be required to issue Common Stock upon conversion of any such Restricted Security to a Person other than the Holder if such Restricted Security is not so accompanied by a properly completed certification, and the Registrar shall not be required to register Common Stock upon conversion of any such Restricted Security in the name of a Person other than the Holder if such Restricted Security is not so accompanied by a properly completed certification.

(c) A Note shall be deemed to have been converted immediately prior to 5:00 p.m., New York City time, on the date on which all of the conversion requirements set forth in Section 12.2(b) have been satisfied, and the person or persons entitled to receive the Common Stock issuable upon such conversion shall be treated for all purposes as the record Holder or Holders of such Common Stock as of 5:00 p.m., New York City time, on such date

(d) In case any Certificated Security shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the Security so surrendered, without charge to such Holder (subject to the provisions of Section 12.8), a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Certificated Securities.

Section 12.3 Adjustment of Conversion Rate.

The Conversion Rate shall be adjusted from time to time as follows:

(a) In case the Company shall, at any time or from time to time after the initial Issue Date while any of the Notes are outstanding, pay a dividend or make a distribution in Common Stock to all or substantially all holders of its outstanding Common Stock, then the Conversion Rate in effect immediately prior to the close of business on the Record Date fixed for the determination of stockholders entitled to receive such dividend or other distribution shall be increased so that the Holder of any Note thereafter surrendered for conversion shall be entitled to receive that number of shares of Common Stock which it would have received had such Note been converted immediately prior to the happening of such event as well as such additional shares it would have received as a result of such event. Such increase shall become effective immediately prior to the opening of business on the day following the Record Date fixed for such determination. If any dividend or distribution of the type described in this Section 12.3(a) is declared but not so paid or made, the Conversion Rate

II-B-53

shall again be adjusted to the Conversion Rate which would then be in effect if such dividend or distribution had not been declared.

(b) In case the Company shall, at any time or from time to time after the initial Issue Date while any of the Notes are outstanding, subdivide its outstanding shares of Common Stock into a greater number of Common Stock or combine its outstanding shares of Common Stock into a smaller number of Common Stock, then the Conversion Rate in effect immediately prior to the close of business on the day upon which such subdivision or combination becomes effective shall be adjusted so that the Holder of any Note thereafter surrendered for conversion shall be entitled to receive that number of shares of Common Stock which it would have received had such Note been converted immediately prior to the happening of such event as well as such additional shares as it would have received as a result of such event. Such adjustment shall become effective immediately prior to the opening of business on the day following the day upon which such subdivision or combination becomes effective.

(c) In case the Company shall, at any time or from time to time after the initial Issue Date while any of the Notes are outstanding, issue rights or warrants for a period expiring within 60 days (other than any rights or warrants referred to in Section 12.3(d)) to all or substantially all holders of its outstanding Common Stock entitling them to subscribe for or purchase Common Stock (or securities convertible into or exchangeable or exercisable for Common Stock), at a price per share of Common Stock (or having a conversion, exchange or exercise price per share of Common Stock) less than the Closing Sale Price of the Common Stock on the Business Day immediately preceding the date of announcement of such issuance (treating the conversion, exchange or exercise price per share of Common Stock of the securities convertible, exchangeable or exercisable into Common Stock as equal to (x) the sum of (i) the price for a unit of the security convertible into or exchangeable or exercisable for Common Stock and (ii) any additional consideration initially payable upon the conversion of or exchange or exercise for such security into Common Stock divided by (y) the number of shares of Common Stock initially underlying such convertible, exchangeable or exercisable security), then the Conversion Rate shall be increased by multiplying the Conversion Rate in effect at the opening of business on the date after such date of announcement by a fraction:

(i) the numerator of which shall be the number of shares of Common Stock outstanding at the close of business on the date of announcement, plus the total number of additional shares of Common Stock so offered for subscription or purchase (or into which the convertible, exchangeable or exercisable securities so offered are convertible, exchangeable or exercisable); and

(ii) the denominator of which shall be the number of shares of Common Stock outstanding on the close of business on the date of announcement, plus the number of shares of Common Stock (or convertible, exchangeable or exercisable securities) which the aggregate offering price of the total number of shares of Common Stock (or convertible, exchangeable or exercisable securities) so offered for subscription or purchase (or the aggregate conversion, exchange or exercise price of the convertible, exchangeable or exercisable securities so offered) would purchase at such Closing Sale Price of the Common Stock.

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

II-B-54

(d)(A) In case the Company shall, at any time or from time to time after the initial Issue Date while any of the Notes are outstanding, by dividend or otherwise, distribute to all or substantially all holders of its outstanding shares of Common Stock (including any such distribution made in connection with a consolidation or merger in which the Company is the continuing corporation and the shares of Common Stock are not changed or exchanged), shares of its capital stock, evidences of its Indebtedness or other assets, including securities, but excluding (i) dividends or distributions of Common Stock referred to in Section 12.3(a), (ii) any rights or warrants referred to in Section 12.3(c), (iii) dividends and distributions paid exclusively in cash referred to in this Section 12.3(d) and (iv) dividends and distributions of stock, securities or other property or assets (including cash) in connection with the reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance to which Section 12.4 applies (such capital stock, evidence of its indebtedness, other assets or securities being distributed hereinafter in this Section 12.3(d) called the “distributed assets”), then, in each such case, subject to paragraphs (D) and (E) of this Section 12.3(d), the Conversion Rate shall be increased by multiplying the Conversion Rate in effect immediately prior to the close of business on the Record Date with respect to such distribution by a fraction:

(ii) the numerator of which shall be the Current Market Price; and

(iii) the denominator of which shall be such Current Market Price of the Common Stock, less the Fair Market Value on such date of the portion of the distributed assets so distributed applicable to one share of Common Stock (determined on the basis of the number of shares of Common Stock outstanding on the Record Date) on such date.

Such increase shall become effective immediately prior to the opening of business on the day following the Record Date for such distribution. In the event that such dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate which would then be in effect if such dividend or distribution had not been declared.

(B) If the Board of Directors determines the Fair Market Value of any distribution for purposes of this Section 12.3(d) by reference to the actual or when issued trading market for any distributed assets comprising all or part of such distribution, it must in doing so consider the prices in such market over the same period (the “Reference Period”) used in computing the Current Market Price pursuant to 0 below to the extent possible, unless the Board of Directors determines in good faith that determining the Fair Market Value during the Reference Period would not be in the best interest of the Holders.

(C) In the event any such distribution consists of shares of capital stock of, or similar equity interests in, one or more of the Company’s Subsidiaries (a “Spin-Off”), the Fair Market Value of the securities to be distributed shall equal the average of the Closing Sale Prices of such securities on the principal securities market on which such securities are traded for the five consecutive Trading Days commencing on and including the sixth Trading Day of those securities after the effectiveness of the Spin-Off, and the Current Market Price shall be measured for the same period. In the event, however, that an underwritten initial public offering of the securities in the Spin-Off occurs simultaneously with the Spin-Off, Fair Market Value of the securities distributed in the Spin-Off shall mean the initial public offering price of such securities and the Current Market Price shall mean the Closing Sale Price for the Common Stock on the same Trading Day.

(D) Rights or warrants distributed by the Company to all holders of the outstanding shares of Common Stock entitling them to subscribe for or purchase Equity Interests of the Company (either initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or events (“Trigger Event”), (x) are deemed to be transferred with such shares of Common Stock, (y) are not exercisable and (z) are also issued in respect of future issuances of shares of Common Stock shall be deemed not to have been distributed for purposes of this Section 12.3(d) (and no adjustment to the Conversion Rate under this Section 12.3(d) shall be required) until the occurrence of the earliest Trigger Event. If such right or warrant is subject to subsequent events, upon the occurrence of which such right or warrant shall become exercisable to purchase different distributed assets, evidences of indebtedness or other assets, or entitle the holder to purchase a different number or amount of the foregoing or to purchase any of the foregoing at a different purchase price, then the occurrence of each such event shall be deemed to be the date of issuance and Record Date with respect to a new right or warrant (and a termination or expiration of the existing right or warrant without exercise by the holder thereof). In addition, in the event of any

II-B-55

distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto, that resulted in an adjustment to the Conversion Rate under this Section 12.3(d):

(i) In the case of any such rights or warrants which shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Rate shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder of shares Common Stock with respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase; and

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

(E) For purposes of this Section 12.3(d) and Section 12.3(a), Section 12.3(b) and Section 12.3(c), any dividend or distribution to which this Section 12.3(d) is applicable that also includes (x) shares of Common Stock, (y) a subdivision or combination of shares of Common Stock to which Section
12.3(b) applies or (z) rights or warrants to subscribe for or purchase shares of Common Stock to which Section 12.3(c) applies (or any combination thereof), shall be deemed instead to be:

(i) a dividend or distribution of the evidences of indebtedness, assets, shares of capital stock, rights or warrants, other than such shares of Common Stock, such subdivision or combination or such rights or warrants to which Section 12.3(a), Section 12.3(b) and Section 12.3(c) apply, respectively (and any Conversion Rate adjustment required by this Section 12.3(d) with respect to such dividend or distribution shall then be made), immediately followed by

(ii) a dividend or distribution of such shares of Common Stock, such subdivision or combination or such rights or warrants (and any further Conversion Rate increase required by Section 12.3(a), Section 12.3(b) and Section 12.3(c) with respect to such dividend or distribution shall then be made), except:

(1) the Record Date of such dividend or distribution shall be substituted as (i) “the date fixed for the determination of stockholders entitled to receive such dividend or other distribution,” “Record Date fixed for such determinations” and “Record Date” within the meaning of Section 12.3(a), (ii) “the day upon which such subdivision or combination becomes effective” within the meaning of Section 12.3(b), and (iii) as “the Record Date fixed for the determination of the stockholders entitled to receive such rights or warrants” and such “Record Date” within the meaning of Section 12.3(c); and

(2) any reduction or increase in the number of shares of Common Stock resulting from such subdivision or combination shall be disregarded in connection with such dividend or distribution.

(e) In case the Company shall, at any time or from time to time after the initial Issue Date while any of the Notes are outstanding, by dividend or otherwise, distribute to all or substantially all holders of its outstanding shares of Common Stock, cash (including any quarterly cash dividends, but excluding any cash that is distributed upon a reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance to which Section 12.4 applies or as part of a distribution referred to in this Section 12.3(d)), then, and in each case, immediately after the close of business on such date, the Conversion Rate shall be increased by multiplying the Conversion Rate in effect immediately prior to the close of business of such Record Date by a fraction:

(A) the numerator of which shall be equal to the Current Market Price on such date; and

II-B-56

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

Such increase shall become effective immediately prior to the opening of business on the day following the Record Date for such distribution. In the event that such distribution is not so made, the Conversion Rate shall again be adjusted to be the Conversion Rate which would then be in effect if such distribution had not been declared.

Notwithstanding the foregoing, adjustments to the Conversion Rate resulting from quarterly cash dividends may not cause the Conversion Rate (as adjusted for any other adjustment) to exceed 28.5714 (the quotient obtained by dividing $1,000 by the last reported sale price per share of the Common Stock on January 21, 2004).

(f) In case a tender offer or exchange offer (other than as part of a stock option exchange offer) made by the Company or any of its Subsidiaries for all or any portion of the Common Stock shall expire, then and in each such case, immediately prior to the opening of business on the day after the date of the last time (the “Expiration Time”) tenders or exchanges could have been made pursuant to such tender offer or exchange offer, the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to the close of business on the date of the Expiration Time by a fraction:

(A) the numerator of which shall be the sum of (x) the product of (i) the number of shares of Common Stock outstanding (excluding any tendered or exchanged shares) at the Expiration Time and (ii) the Current Market Price of the Common Stock at the Expiration Time, and (y) the Fair Market Value of the aggregate consideration payable to stockholders based on acceptance (up to any maximum specified in the terms of the tender offer or exchange offer) of all shares validly tendered and not withdrawn as of the Expiration Time; and

(B) the denominator of which shall be the product of the number of shares of Common Stock outstanding (including any tendered or exchanged shares) at the Expiration Time and the Current Market Price of the Common Stock at the Expiration Time.

Such increase (if any) shall become effective immediately prior to the opening of business on the day following the Expiration Time. In the event that the Company is obligated to purchase shares pursuant to any such tender offer or exchange offer, but the Company is permanently prevented by applicable law from effecting any such purchases or all or a portion of such purchases are rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate which would then be in effect if such (or such portion of the) tender offer or exchange offer had not been made. If the application of this 0 to any tender offer or exchange offer would result in a decrease in the Conversion Rate, no adjustment shall be made for such tender offer or exchange offer under this 0.

To the extent that the Company has a Rights Plan in effect upon the conversion of the Notes into Common Stock only or a combination of cash and Common Stock, with respect to the conversion consideration payable in Common Stock, a Holder will receive in addition to the Common Stock, the rights under the Rights Plan, whether or not the rights have separated from the Common Stock. To the extent that the Company has a Rights Plan in effect upon conversion of the Notes into cash, with respect to the conversion consideration payable in cash, a Holder will not receive any rights under the Rights Plan or other consideration in respect thereof.

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

“Current Market Price” on any date means the average of the daily Closing Sale Prices per share of Common Stock for the ten consecutive Trading Days immediately prior to such date; provided, however, that if:

(i) the “ex” date (as hereinafter defined) for any event (other than the issuance or distribution requiring such computation) that requires an adjustment to the Conversion Rate pursuant to Section 12.3(a),

II-B-57

Section 12.3(b), Section 12.3(c), Section 12.3(d), 0 or 0 occurs during such ten consecutive Trading Days, the Closing Sale Price for each Trading Day prior to the “ex” date for such other event shall be adjusted by multiplying such Closing Sale Price by the same fraction by which the Conversion Rate is so required to be adjusted as a result of such other event;

(ii) the “ex” date for any event (other than the issuance or distribution requiring such computation) that requires an adjustment to the Conversion Rate pursuant to Section 12.3(a), Section 12.3(b), Section 12.3(c), Section 12.3(d), 0 or 0 occurs on or after the “ex” date for the issuance or distribution requiring such computation and prior to the day in question, the Closing Sale Price for each Trading Day on and after the “ex” date for such other event shall be adjusted by multiplying such Closing Sale Price by the reciprocal of the fraction by which the Conversion Rate is so required to be adjusted as a result of such other event; and

(iii) the “ex” date for the issuance or distribution requiring such computation is prior to the day in question, after taking into account any adjustment required pursuant to clause (1) or (2) of this proviso, the Closing Sale Price for each Trading Day on or after such “ex” date shall be adjusted by adding thereto the amount of any cash and the Fair Market Value (as determined by the Board of Directors in a manner consistent with any determination of such value for purposes of Section 12.3(d), 0 or 0) of the evidences of Indebtedness, shares of capital stock or assets being distributed applicable to one share of Common Stock as of the close of business on the day before such “ex” date.

For purposes of any computation under 0, if the “ex” date for any event (other than the tender offer requiring such computation) that requires an adjustment to the Conversion Rate pursuant to Section 12.3(a), Section 12.3(b), Section 12.3(c), Section 12.3(d), 0 or 0 occurs on or after the Expiration Time for the tender or exchange offer requiring such computation and prior to the day in question, the Closing Sale Price for each Trading Day on and after the “ex” date for such other event shall be adjusted by multiplying such Closing Sale Price by the reciprocal of the fraction by which the Conversion Rate is so required to be adjusted as a result of such other event. For purposes of this paragraph, the term “ex” date, when used:

(i) with respect to any issuance or distribution, means the first date on which the Common Stock trade 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 issuance or distribution;

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

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

Notwithstanding the foregoing, whenever successive adjustments to the Conversion Rate are called for pursuant to this Section 12.3, such adjustments shall be made to the Current Market Price as may be necessary or appropriate to effectuate the intent of this Section 12.3 and to avoid unjust or inequitable results as determined in good faith by the Board of Directors.

“Fair Market Value” means the amount which a willing buyer would pay a willing seller in an arm’s length transaction (as determined by the Board of Directors, whose determination shall be made in good faith and, absent manifest error, shall be final and binding on Holders of the Securities).

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

II-B-58

(h) The Company shall be entitled to make such additional increases in the Conversion Rate, in addition to those required by Section 12.3(a), Section 12.3(b), Section 12.3(c), Section 12.3(d), 0 or 0 if the Board of Directors determines that it is advisable, subject to compliance with Nasdaq Marketplace Rule 4350(i), in order that any dividend or distribution of Common Stock, any subdivision, reclassification or combination of Common Stock or any issuance of rights or warrants referred to above shall not be taxable to the holders of Common Stock for United States federal income tax purposes.

(i) To the extent permitted by applicable law, the Company may, from time to time, increase the Conversion Rate by any amount for any period of time if such period is at least 20 calendar days, the increase is irrevocable during the period and the Board of Directors, in good faith and absent manifest error, determines that such increase would be in the best interest of the Company, subject to compliance with Nasdaq Marketplace Rule 4350(i). Whenever the Conversion Rate is increased pursuant to the preceding sentence or clause (h) above, the Company shall mail to the Trustee and each Holder at the address of such Holder as it appears in the register of the Securities maintained by the Registrar, at least 15 calendar days prior to the date the increased Conversion Rate takes effect, a notice of the increase stating the increased Conversion Rate and the period during which it shall be in effect.

(j) In any case in which this Section 12.3 shall require that any adjustment be made effective as of or retroactively immediately following a Record Date, the Company may elect to defer (but only for five Trading Days following the filing of the notice referred to in Section 12.5) issuing to the Holder of any Securities converted after such Record Date the Common Stock issuable upon such conversion over and above the Common Stock issuable upon such conversion on the basis of the Conversion Rate prior to adjustment; provided, however, that the Company shall deliver to such Holder a due ▇▇▇▇ or other appropriate instrument evidencing such Holder’s right to receive such additional Common Stock upon the occurrence of the event requiring such adjustment.

(k) All calculations under this Section 12.3 shall be made to the nearest cent or one-hundredth of a share, with one-half cent and 0.005 of a share, respectively, being rounded upward. Notwithstanding any other provision of this Section 12.3, the Company shall not be required to make any adjustment of the Conversion Rate unless such adjustment would require an increase or decrease of at least 1% in the Conversion Rate as last adjusted. Any lesser adjustment shall be carried forward and shall be made at the time of and together with the next subsequent adjustment which, together with any adjustment or adjustments so carried forward, shall amount to an increase or decrease of at least 1% in the Conversion Rate as last adjusted. Any adjustments under this Section 12.3 shall be made successively whenever an event requiring such an adjustment occurs.

(l) In the event that at any time, as a result of an adjustment made pursuant to this Section 12.3, the Holder of any Securities thereafter surrendered for conversion shall become entitled to receive any shares of Applicable Stock of the Company other than Common Stock into which the Securities originally were convertible, the Conversion Rate of such other shares so receivable upon conversion of any such Note shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to Common Stock contained in subparagraphs (a) through (k) of this Section 12.3, and the provision of Section 12.1, Section 12.2 and Section 12.4 through Section 12.9 with respect to the Common Stock shall apply on like or similar terms to any such other shares (including, without limitation, the determination of whether the conditions to conversion provided in Section 12.1 have been satisfied). In the event that the Conversion Rate is required to be adjusted pursuant to this Section 12.3 during any period referred to in Section 12.1(a)(i) or any Cash Settlement Averaging Period, the Closing Sale Price for each Trading Day during such period shall, to the extent necessary, be adjusted to reflect the effects of such adjustment to this Section 12.3

(m) No adjustment shall be made pursuant to this Section 12.3 if the effect thereof would be to reduce the Conversion Price below the par value (if any) of the Common Stock. In addition, it is understood and agreed that no adjustment shall be made to the Conversion Rate due to Principal Accretion on the Notes.

Section 12.4 Consolidation or Merger of the Company.

If any of the following events occurs, namely:

II-B-59

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

(b) any merger, consolidation, statutory share exchange or combination of the Company with another Person as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Common Stock; or

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

the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the Trust Indenture Act as in force at the date of execution of such supplemental indenture, if such supplemental indenture is then required to so comply) providing that such Securities shall be convertible into the kind and amount of shares of stock and other securities or property or assets (including cash) which such Holder would have been entitled to receive upon such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance had such Notes been converted into Common Stock immediately prior to such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance assuming such holder of Common Stock did not exercise its rights of election, if any, as to the kind or amount of securities, cash or other property receivable upon such merger, consolidation, statutory share exchange, sale or conveyance (provided, that if the kind or amount of securities, cash or other property receivable upon such merger, consolidation, statutory share exchange, sale or conveyance is not the same for each share of Common Stock in respect of which such rights of election shall not have been exercised (“Non-Electing Share”), then for the purposes of this Section 12.4, the kind and amount of securities, cash or other property receivable upon such merger, consolidation, statutory share exchange, sale or conveyance for each Non-Electing Share shall be deemed to be the kind and amount so receivable per share by a plurality of the Non-Electing Shares). Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this ARTICLE XII and, to the extent applicable, reflect the other types of adjustments provided for in Section 12.3(l). If, in the case of any such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance, the stock or other securities and assets receivable thereupon by a holder of Common Stock includes shares of stock or other securities and assets of a Person other than the successor or purchasing Person, as the case may be, in such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance, then such supplemental indenture shall also be executed by such other Person and shall contain such additional provisions to protect the interests of the Holders of the Notes as the Board of Directors shall reasonably consider necessary by reason of the foregoing including the provisions providing for the repurchase rights set forth in ARTICLE IV and ARTICLE V.

The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Holder, at the address of such Holder as it appears on the register of the Securities maintained by the Registrar, within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture.

The above provisions of this Section 12.4 shall similarly apply to successive reclassifications, mergers, consolidations, statutory share exchanges, combinations, sales and conveyances.

If this Section 12.4 applies to any event or occurrence, Section 12.3 shall not apply.

Section 12.5 Notice of Adjustment.

Whenever an adjustment in the Conversion Rate with respect to the Securities is required:

(a) the Company shall forthwith place on file with the Trustee and any Conversion Agent for such securities a certificate of the Chief Financial Officer of the Company, stating the adjusted Conversion Rate

II-B-60

determined as provided herein and setting forth in reasonable detail such facts as shall be necessary to show the reason for and the manner of computing such adjustment; and

(b) a notice stating that the Conversion Rate has been adjusted and setting forth the adjusted Conversion Rate shall forthwith be given by the Company or, at the Company’s request, by the Trustee in the name and at the expense of the Company, to each Holder in the manner provided in Section 17.2. Any notice so given shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice.

Section 12.6 Notice in Certain Events.

In case of:

(a) a consolidation or merger to which the Company is a party and for which approval of any stockholders of the Company is required, or of the sale or conveyance to another Person or entity or group of Persons or entities acting in concert as a partnership, limited partnership, syndicate or other group (within the meaning of Rule 13d-3 under the Exchange Act) of all or substantially all of the property and assets of the Company; or

(b) the voluntary or involuntary dissolution, liquidation or winding up of the Company; or

then, in each case, the Company shall cause to be filed with the Trustee and the Conversion Agent, and shall cause to be given, to the Holders of the Securities in the manner provided in Section 17.2, at least 15 days prior to the applicable date hereinafter specified, a notice stating:

(x) the date on which a record is to be taken for the purpose of any distribution or grant of rights or warrants triggering an adjustment to the Conversion Rate pursuant to this ARTICLE XII, or, if a record is not to be taken, the date as of which the holders of record of Common Stock entitled to such distribution, rights or warrants are to be determined; or

(y) the date on which any reclassification, consolidation, merger, sale, conveyance, dissolution, liquidation or winding up triggering an adjustment to the Conversion Rate pursuant to this ARTICLE XII is expected to become effective, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities or other property deliverable upon such reclassification, consolidation, merger, sale, conveyance, dissolution, liquidation or winding up.

Failure to give such notice or any defect therein shall not affect the legality or validity of the proceedings described in Section 12.6(a), Section
12.6(b) or Section 12.6(c).

Section 12.7 Company To Reserve Stock: Registration; Listing.

(a) The Company shall, prior to issuance of any Securities hereunder, and from time to time as may be necessary, reserve and keep available, free from preemptive rights, out of its authorized but unissued Common Stock, for the purpose of effecting the conversion of the Securities, such number of its duly authorized Common Stock as shall from time to time be sufficient to effect the conversion of all Securities then outstanding into such Common Stock at any time (assuming that, at the time of the computation of such number of Common Stock, all such Securities would be held by a single Holder). The Company covenants that all Common Stock which may be issued upon conversion of Securities shall upon issue be fully paid and nonassessable and free from all liens and charges and, except as provided in Section 12.8, taxes with respect to the issue thereof.

(b) Except with respect to shares issued upon conversion of a Transfer Restricted Security prior to the second anniversary of the initial Issue Date, if any shares of Applicable Stock which would be issuable

II-B-61

upon conversion of Securities hereunder (including, without limitation, in connection with any transaction referred to in Section 12.4) require registration with or approval of any governmental authority before such shares may be issued upon such conversion, the Company shall use its reasonable best efforts to cause such shares to be duly registered or approved, as the case may be, or to cause such shares not to be Transfer Restricted Securities. In addition, in connection with any transaction referred to in Section 12.4, the Company and any parent company of the Company required to issue Applicable Stock upon conversion of a Note shall take such actions as are required to entitle the Company or such parent company, as the case may be, to rely on Section 3(a)(9) of the Securities Act in connection with conversion of the Securities without extending any holding periods under Rule 144 or otherwise permit such Applicable Stock issued upon conversion of the Securities to be resold without requiring registration thereof under the Securities Act.

(c) The Company further covenants that so long as the Common Stock shall be quoted on the Nasdaq National Market system, the Company shall use its reasonable best efforts, if permitted by the rules of the Nasdaq National Market system, to keep so quoted all Common Stock issuable upon conversion of the Securities, and the Company shall use its reasonable best efforts to list or obtain approval for the quotation of the Common Stock to be delivered upon conversion of the Securities prior to such delivery upon any other national securities exchange or quotation system upon which the outstanding Common Stock is listed or quoted at the time of such delivery.

Section 12.8 Taxes on Conversion.

The issue of stock certificates on conversion of Securities shall be made without charge to the converting Holder for any documentary, stamp or similar issue or transfer taxes in respect of the issue thereof, and the Company shall pay any and all documentary, stamp or similar issue or transfer taxes that may be payable in respect of the issue or delivery of Common Stock on conversion of Securities pursuant hereto. The Company shall not, however, be required to pay any such tax which may be payable in respect of any transfer involved in the issue or delivery of Common Stock or the portion, if any, of the Securities which are not so converted in a name other than that in which the Securities so converted were registered, and no such issue or delivery shall be made unless and until the Person requesting such issue has paid to the Company the amount of such tax or has established to the satisfaction of the Company that such tax has been paid.

Section 12.9 Conversion After Regular Record Date.

Except as provided in the succeeding paragraph, upon conversion, the Holder of Securities shall not be entitled to receive any accrued and unpaid interest or Additional Interest, if any.

If any Securities are surrendered for conversion subsequent to the close of business on any Regular Record Date but prior to the opening of business on the corresponding Interest Payment Date, the Holder of such Securities at the close of business on such Regular Record Date shall receive the interest, Contingent Interest and Additional Interest, if any, payable on such Securities on such Interest Payment Date notwithstanding the conversion thereof. Securities surrendered for conversion during the period from the close of business on any Regular Record Date to the opening of business on the corresponding Interest Payment Date shall (except in the case of Securities which have been called for redemption on a Redemption Date within such period or Securities surrendered for conversion after acceleration of the Securities) be accompanied by payment by Holders, for the account of the Company, in New York Clearing House funds or other funds acceptable to the Company of an amount equal to the interest, Contingent Interest and Additional Interest, if any, payable on such interest payment date on the Securities being surrendered for conversion.

Except as described in Section 12.2(a) and this Section 12.9, the Company will not make any payment in cash or Common Stock or other adjustment for accrued and unpaid interest, Contingent Interest or Additional interest on any Securities when they are converted.

II-B-62

Section 12.10 Company Determination Final.

Excepts as otherwise provided herein or the Note, the Company or its agents shall be responsible for making all calculations required under the terms of this ARTICLE XII. Any determination that the Company or the Board of Directors must make pursuant to this ARTICLE XII shall be set forth in a Board Resolution, shall be made in good faith and, absent manifest error, shall be final and binding on holders of the Securities. The Company or its agents shall be required to deliver to the Trustee a schedule of its calculations and the Trustee shall be entitled to conclusively rely upon the accuracy of such calculations without independent verification.

Section 12.11 Responsibility of Trustee for Conversion Provisions.

The Trustee has no duty to determine when an adjustment under this ARTICLE XII should be made, how it should be made or what it should be. The Trustee makes no representation as to the validity or value of any securities or assets issued upon conversion of Securities. The Trustee shall not be responsible for any failure of the Company to comply with this ARTICLE XII. Each Conversion Agent other than the Company shall have the same protection under this Section 12.11 as the Trustee.

The rights, privileges, protections, immunities and benefits given to the Trustee under this Indenture including, without limitation, its rights to be indemnified, are extended to, and shall be enforceable by, other than the Company, the Trustee in each of its capacities hereunder, and each Paying Agent or Conversion Agent, other than the Company, acting hereunder.

Section 12.12 Unconditional Right of Holders to Convert.

Notwithstanding any other provision in this Indenture, the Holder of any Note shall have the right, which is absolute and unconditional, to convert its Note in accordance with this ARTICLE XII and to bring an action against the Company for the enforcement of any such right to convert, and such rights shall not be impaired or affected without the consent of such Holder.

Section 12.13 Option to Satisfy Conversion Obligation with Cash, Common Stock or Combination Thereof.

(a) If the Company receives any Holder’s Conversion Notice on or prior to the day that is 31 Trading Days prior to the Stated Maturity (the “Final Notice Date”), then the Company shall notify the Holder through the Trustee, at any time on or before the date that is three Trading Days following receipt of the Conversion Notice required pursuant to Section 12.2 (such period, the “Settlement Notice Period”) of the method the Company chooses to settle its obligation upon conversion of the Securities as provided in Section 12.1(a) (the “Conversion Obligation”). If the Company fails to give notice during the Settlement Notice Period as provided in this Section 12.13(a), then the Company shall be obligated to settle the entire Conversion Obligation by delivering shares of Common Stock (plus cash paid in lieu of issuing any fractional shares). If the Company elects to settle its Conversion Obligation in a combination of cash and Common Stock, the Company shall specify the percentage of the Conversion Obligation relating to the Securities surrendered for conversion that it will pay in cash. The remainder of its Conversion Obligation will be settled in shares of Common Stock (except that cash will be paid in lieu of issuing any fractional shares). The Company shall treat all Holders converting on the same Trading Day in the same manner and the Company shall not have any obligation to settle Conversion Obligations arising on different Trading Days in the same manner.

If the Company timely elects to pay cash for any portion of the Conversion Obligation, the Holder may retract the Conversion Notice at any time during the two Trading Day period beginning on the Trading Day after the Settlement Notice Period (the “Conversion Retraction Period”); provided, that no such retraction can be made (and a Conversion Notice shall be irrevocable) if the Company does not elect to deliver cash, or a combination of cash and shares, in lieu of shares (other than cash in lieu of fractional shares). Settlement in Common Stock only will be made in accordance with Section 12.2(a). If the Conversion Notice has not been retracted, then settlement in cash or in a combination of cash and Common Stock will, subject to Section 12.13(c), be made on the third Trading Day following the final Trading Day of the 20 Trading Day period beginning on the third Trading Day following the

II-B-63

end of the Conversion Retraction Period (the “Cash Settlement Averaging Period”), assuming all of the other requirements have been satisfied by such Holder.

Settlement amounts will be computed as follows (subject to the provisions of the fourth paragraph of Section 12.1(a) in connection with conversions during a Registration Default Period):

(i) if the entire Conversion Obligation is to be settled in Common Stock, the Company shall deliver to such Holder a number of shares of Common Stock equal to the product of (1) the aggregate Principal Amount at Issuance of Securities to be converted divided by 1,000, multiplied by (2) the Conversion Rate (plus any cash paid for fractional shares);

(ii) if the entire Conversion Obligation is to be settled in cash, the Company shall deliver to such Holder cash in an amount equal to the product of:

(1) the product of (x) the aggregate original principal amount of Securities to be converted divided by 1,000, multiplied by (y) the Conversion Rate, multiplied by

(2) the arithmetic average of the Closing Sale Prices of Common Stock during the Cash Settlement Averaging Period; and

(iii) if a portion of the Conversion Obligation is to be settled in cash (the “Cash Amount”) (excluding any cash paid for fractional shares) and a portion of the Conversion Obligation is to be settled in Common Stock, the Company shall deliver to such Holder:

(1) a Cash Amount equal to the product of (x) the percentage of the Conversion Obligation to be satisfied in cash, multiplied by (y) the amount of cash that would be paid pursuant to clause (ii) above;

and

(2) a number of shares of Common Stock equal to the remainder of (x) the number of shares that would be issued pursuant to clause (i) above minus (y) the number of shares of Common Stock equal to the quotient of (A) the Cash Amount divided by (B) the arithmetic average of the Closing Sale Prices of the Common Stock during the Cash Settlement Averaging Period.

(b) The Company shall settle all of its Conversion Obligations arising after the Final Notice Date in the same manner. On or prior to the Final Notice Date, the Company shall notify the Holders through the Trustee of the method it chooses to settle any Conversion Obligations arising after the Final Notice Date. If the Company elects to settle any Conversion Obligations arising after the Final Notice Date in a combination of cash and Common Stock, the Company shall specify the percentage of the Conversion Obligation that it will pay in cash. The remainder of any Conversion Obligation arising after the Final Notice Date shall be settled in shares of Common Stock (except that cash will be paid in lieu of issuing any fractional shares). All Conversion Notices received after the Final Notice Date shall be irrevocable.

Settlement of Conversion Obligations arising after the Final Notice Date in Common Stock only shall be made in accordance with Section 12.2(a). Settlement of Conversion Obligations arising after the Final Notice Date in cash or in a combination of cash and Common Stock shall be made on the third Trading Day following the final Trading Day of the Cash Settlement Averaging Period described in the following sentence. The settlement amount of Common Stock, cash or combination of cash and Common Stock in satisfaction of Conversion Obligations arising after the Final Notice Date shall be computed in the same manner as set forth in Section 12.13(a), except that the “Cash Settlement Averaging Period” shall be the 20 Trading Day period beginning on the date that is the 23rd Trading Day prior to the Stated Maturity.

II-B-64

(c) If any Trading Day during a Cash Settlement Averaging Period is not an Undisrupted Trading Day, then determination of the price for that day will be delayed until the next Undisrupted Trading Day on which a pricing is not otherwise observed and such day will not count as one of the 20 Trading Days that constitute the Cash Settlement Averaging Period. If this results in a price being observed later than the eighth Trading Day after the last of the original 20 Trading Days in the Cash Settlement Averaging Period, then the Company will determine all prices for all delayed and undetermined prices on that eighth Trading Day based on its good faith estimate of the value of the Common Stock on that date. In the event that any Trading Day during the Cash Settlement Averaging Period beginning on the date that is the 23^rd Trading Day prior to the Stated Maturity is not an Undisrupted Trading Day, settlement will occur after the Stated Maturity.

ARTICLE XIII

CONTINGENT INTEREST

Section 13.1 Contingent Interest. The Company shall make Contingent Interest payments to the Holders of Notes, as set forth in Section 13.2 below, during any six month period from February 1 to July 31 and from August 1 to January 31, commencing with the six-month period beginning on February 1, 2009 (each a “Contingent Interest Period”), if the average Note Price for the applicable Five-Trading-Day Measurement Period to, but excluding, the day immediately preceding the first day of the relevant Contingent Interest Period equals 120% or more of the Accreted Principal Amount of such Note. During any Contingent Interest Period when Contingent Interest is payable pursuant to this Section 13.1, each Contingent Interest payment due and payable on each $1,000 Principal Amount at Issuance of a Note shall equal interest accruing at the rate of 0.25% per annum on the average Note Price for the five Trading Days in the relevant Five-Trading-Day Measurement Period. Contingent Interest on the Notes shall be computed on the basis of a 360-day year consisting of twelve 30-day months.

Section 13.2 Payment of Contingent Interest; Contingent Interest Rights Preserved. Contingent Interest shall be paid on February 1 in respect of any Contingent Interest Period ended on January 31 and on August 1 in respect of any Contingent Interest Period ended on July 31 (in each case, a “Contingent Interest Payment Date”). Each payment of Contingent Interest on any Note shall be payable as provided in Section 6.1 and the method specified for semi-annual cash interest payments in the form of Security attached hereto as Exhibit A.

The Company may unilaterally increase the amount of Contingent Interest it may pay or pay interest or other amounts it is not obligated to pay, but it will have no obligation to do so.

Upon determination that Holders will be entitled to receive Contingent Interest during a Contingent Interest Period, the Company shall promptly make a Public Notice containing such information and notify the Trustee.

The Company and each Holder by its acceptance of a Note will be deemed to have agreed for United States federal income tax purposes, to treat the notes as contingent payment debt instruments (“Contingent Payment Debt Instruments”) subject to the regulation governing Contingent Payment Debt Instruments set forth in Section 14.1.

Section 13.3 Bid Solicitation Agent. The Bid Solicitation Agent will initially be the Trustee. The Bid Solicitation Agent shall solicit bids during each Five-Trading-Day Measurement Period prior to any Contingent Interest Period from securities dealers which the Company indicates that it believes are willing to bid for the Securities. The Company may change the Bid Solicitation Agent at its discretion, but the Bid Solicitation Agent may not be the Company or an Affiliate of the Company.

ARTICLE XIV

TAX TREATMENT

Section 14.1 Tax Treatment. The Company agrees, and by acceptance of beneficial ownership interest in the Securities each beneficial holder of the Securities will be deemed to have agreed, for United States federal income tax purposes (1) to treat the Securities as indebtedness that is subject to Treas. Reg. Sec. 1.1275-4 (the “Contingent Payment Regulations”) and, for purposes of the Contingent Payment Regulations, to treat the fair market value of any stock beneficially received by a beneficial holder upon any conversion of the Securities as a

II-B-65

contingent payment and (2) to be bound by the Company’s determination of the “comparable yield” and “projected payment schedule,” within the meaning of the Contingent Payment Regulations, with respect to the Securities. A Holder may obtain the issue price, amount of original issue discount, issue date, yield to maturity, comparable yield and projected payment schedule for the Securities by submitting a written request for such information to the Company at the following address: Comtech Telecommunications Corp., ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, Attention: Chief Financial Officer.

ARTICLE XV

SUBSIDIARY GUARANTEES

Section 15.1 Agreement to Guarantee. Subject to the provisions of this ARTICLE XV and of ARTICLE XVI, the Guarantors, jointly and severally, hereby agree as follows:

(a) Each Guarantor unconditionally and irrevocably guarantees, as primary obligor and not merely as surety, to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, regardless of the validity and enforceability of the Indenture, the Securities or the Obligations of the Company under this Indenture or the Securities:

(1) the full and punctual payment of the Accreted Principal Amount of and interest (including Contingent Interest and Additional Interest) on the Note when due, whether at maturity, by acceleration, redemption, purchase in accordance with ARTICLE IV or ARTICLE V or otherwise, and interest on the overdue principal of and interest (including Contingent Interest and Additional Interest, if any) on the Note, to the extent lawful, and all other Obligations of the Company to the Holders or the Trustee thereunder or under this Indenture when due, all in accordance with the terms thereof; and

(2) in case of any extension of time for payment or renewal on or of any Note or any of such other Obligations, that the same will be promptly paid in full when due in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise.

To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of each Guarantor will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this ARTICLE XV, result in the obligations of such Guarantor under its Guarantee not constituting a fraudulent transfer or conveyance under applicable law. As provided in, and subject to the limitations of, clause (h) (3) below, each Guarantor that makes a payment for distribution under its Guarantee is entitled to a contribution from each other Guarantor.

(c) The Guarantors confirm that the Guarantee set forth herein are given for value in consideration of the direct and indirect benefit each such Guarantor will receive as a result of the issuance of the Securities.

(d) Each Guarantor agrees that its Guarantee herein constitutes a guarantee of payment when due (and not a guarantee of collection).

(e) The Guarantors hereby, jointly and severally, agree that their obligations hereunder shall be unconditional, regardless of the validity, regularity or enforceability of the Notes or the Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions of the Notes or the Indenture, any recission, waiver, amendment or modification of any of the terms of

II-B-66

this Indenture or any Note or any extension or renewal of any thereof, the failure to exercise any right or remedy against any other Guarantor, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor.

(f) The Guarantors hereby waive, to the extent permitted by applicable law, diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that the Guarantees made pursuant to this Indenture will not be discharged except by complete performance of the obligations contained in the Securities and the Indenture or as provided in Section 15.3.

(g) If any Holder or the Trustee is required by any court or otherwise to return to the Company or the Guarantors, or any Custodian, Trustee, liquidator or other similar official acting in relation to either the Company or the Guarantors, any amount paid by either to the Trustee or such Holder, the Guarantees made pursuant to this Indenture, to the extent theretofore discharged, shall be reinstated in full force and effect.

(h) The Guarantors agree that they shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. The Guarantors further agree that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand:

(1) the maturity of the Obligations guaranteed hereby may be accelerated as provided in ARTICLE VIII of the Indenture for the purposes of the Guarantees made pursuant to this Indenture, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby; and

(2) in the event of any declaration of acceleration of such obligations as provided in ARTICLE VIII of the Indenture, such Obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantors for the purpose of the Guarantees made pursuant to this Indenture.

(3) The Guarantors shall have the right to seek contribution from any other non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders or the Trustee under the Guarantees made pursuant to this Indenture.

(i) The Guarantee of each Guarantor is subordinated in right of payment, to the extent and in the manner provided in ARTICLE XVI, to the prior payment in full in cash or other consideration satisfactory to holders of Guarantor Senior Debt of all Guarantor Senior Debt of such Guarantor.

Section 15.2 Execution and Delivery of Guarantees. To evidence the Guarantees set forth in this Indenture, the Guarantors hereby agree that a notation of such Guarantees shall be endorsed by an officer of each of the Guarantors on each Note authenticated and delivered by the Trustee after the date hereof; provided that the failure to make such notation shall not effect the validity of the Guarantee of any Guarantor.

(a) Notwithstanding the foregoing, the Guarantors hereby agree that the Guarantees set forth herein shall be and shall remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Guarantees.

(b) If an Officer whose signature is on this Indenture no longer holds that office at the time the Trustee authenticates the Note on which the Guarantees are endorsed, the Guarantees shall be valid nevertheless.

(c) The delivery of any Security by the Trustee, after the authentication thereof under the Indenture, shall constitute due delivery of the Guarantees set forth in this Indenture on behalf of the Guarantors.

II-B-67

Section 15.3 Releases. A Guarantor shall be released from its obligations under its Guarantee and its obligations under this Indenture and the Registration Rights Agreement in the event of a sale or other disposition of all or substantially all of the assets of such Guarantor or a sale or other disposition of all of the Equity Interests of such Guarantor then held directly or indirectly by the Company, in each case including by way of merger, consolidation or otherwise, to a Person which is not a Subsidiary of the Company.

The Trustee shall execute an appropriate instrument prepared by the Company evidencing the release of a Guarantor pursuant to this Section 15.3 from its obligations under its Guarantee and this Indenture upon receipt of a request by the Company or such Guarantor accompanied by an Officers’ Certificate and an Opinion of Counsel certifying as to the compliance with this Section 15.3; provided, however, that the legal counsel delivering such Opinion of Counsel may rely as to matters of fact on one or more Officers’ Certificates of the Issuer.

Nothing contained in this Indenture or in any of the Notes shall prevent any consolidation or merger of a Guarantor with or into the Issuer (in which case such Guarantor shall no longer be a Guarantor) or another Guarantor or shall prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Issuer or another Guarantor.

Section 15.4 No Recourse Against Others. No past, present or future director, officer, employee, incorporator, stockholder or agent of the Guarantors, as such, shall have any liability for any obligations of the Company or any Guarantor under the Notes, any Guarantees, this Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of the Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Note. Such waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the SEC that such a waiver is against public policy.

Section 15.5 Future Subsidiary Guarantees; Successors.

(a) The Notes shall be initially guaranteed by all of the Company’s consolidated Subsidiaries that are Subsidiaries on the date of this Indenture.

ARTICLE XVI

SUBORDINATION OF GUARANTEES

Section 16.1 Agreement to Subordinate.

Each Guarantor agrees, and each holder of Securities by accepting a Security agrees, that payment under each Guarantee is subordinated in right of payment, to the extent and in the manner provided in this ARTICLE XVI, to the prior payment in full in cash or other consideration satisfactory to holders of Guarantor Senior Debt of such Guarantor of all Guarantor Senior Debt (whether outstanding on the date hereof or hereafter created, incurred, assumed or guaranteed) of such Guarantor, and that the subordination is for the benefit of the holders of Guarantor Senior Debt of such Guarantor.

Section 16.2 Liquidation, Dissolution, Bankruptcy.

Upon any distribution to creditors of a Guarantor in a liquidation or dissolution of such Guarantor or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to such Guarantor or its property, in an assignment for the benefit of creditors or any marshaling of such Guarantor’s assets and liabilities:

(i) holders of Guarantor Senior Debt of such Guarantor shall be entitled to receive payment in full of all obligations due in respect of such Guarantor Senior Debt (including interest after the commencement of any such proceeding at the rate specified in the applicable Guarantor Senior Debt) in cash or other consideration satisfactory to the holders of such Guarantor Senior Debt before Holders of Securities shall be entitled to receive any payment with respect to the Guarantee of such Guarantor; and

(ii) until all Guarantor Senior Debt of such Guarantor is paid in full in cash or other consideration satisfactory to the holders of such Guarantor Senior Debt, any payment under its Guarantee from such Guarantor in respect of its Guarantee to which holders of Securities would be entitled but for this ARTICLE XVI shall be made to holders of the Guarantor Senior Debt of such Guarantor, as their interests may appear.

Section 16.3 Default on Guarantor Senior Debt and/or Designated Guarantor Senior Debt.

(a) In the event of any default in payment of the principal of or premium, if any, or interest on, or any other payment obligation under any Guarantor Senior Debt of a Guarantor beyond any applicable grace period with respect thereto (a “Payment Default”), then, until all such payments due in respect of such Guarantor Senior Debt have been paid in full in cash or other consideration satisfactory to holders of such Guarantor Senior Debt or such default shall have been cured or waived or shall have ceased to exist, no payment shall be made by such Guarantor under its Guarantee.

(b) In addition, if a Guarantor shall receive written notice from one or more holders of Designated Guarantor Senior Debt of such Guarantor or one or more representatives of such holder or holders that there has occurred and is continuing under such Designated Guarantor Senior Debt, or any agreement pursuant to which such Designated Guarantor Senior Debt is issued, any default (other than a Payment Default), which default shall not have been cured or waived, giving the holders of such Designated Guarantor Senior Debt the right to declare such Designated Guarantor Senior Debt immediately due and payable (a “Payment Blockage Notice”), then, anything contained in this Indenture to the contrary notwithstanding, no payment on account of the Guarantee of such Guarantor shall be made by such Guarantor during the period (the “Payment Blockage Period”) commencing on the date of receipt of the Payment Blockage Notice and ending on the earlier of 179 calendar days thereafter or the date on which such non-Payment Default is cured or waived.

Notwithstanding the provisions described in the immediately preceding sentence (but subject to the provisions contained in Section 16.1 and the first sentence of this Section 16.3), unless the holder(s) of such Designated Guarantor Senior Debt or the representative(s) of such holder(s) shall have accelerated the maturity of such Designated Guarantor Senior Debt, the Guarantor may resume payments on its Guarantee after the end of such

II-B-69

Payment Blockage Period. No new Payment Blockage Period may be commenced unless 360 calendar days have elapsed since the effectiveness of the prior Payment Blockage Notice. No default under Designated Guarantor Senior Debt that is not a Payment Default that existed or was continuing on the date of delivery of any Payment Blockage Notice delivered to a Guarantor shall be, or be made, the basis of a subsequent Payment Blockage Notice to such Guarantor.

Section 16.4 Acceleration of Securities.

If payment is to be made under the Guarantee of a Guarantor because payment of the Notes is accelerated because of an Event of Default, each Guarantor shall promptly notify holders of its Guarantor Senior Debt or trustee(s) of such Guarantor Senior Debt.

Section 16.5 When Distribution Must Be Paid Over.

In the event that the Trustee, any Holder of Securities or any other person receives any payment by a Guarantor or distribution of assets of a Guarantor of any kind with respect to the Guarantee of such Guarantor in contravention of any terms contained in this ARTICLE XVI, whether in cash, property or securities, including, without limitation, by way of set-off or otherwise, then such payment or distribution shall be held by the recipient in trust for the benefit of holders of Guarantor Senior Debt of such Guarantor, and shall be immediately paid over and delivered to the holders of such Guarantor Senior Debt or their representative(s), to the extent necessary to make payment in full in cash or other consideration satisfactory to such holders of all such Guarantor Senior Debt remaining unpaid, after giving effect to any concurrent payment or distribution or provision therefor, to or for the holders of such Guarantor Senior Debt; provided, that the foregoing shall apply to the Trustee only if a Responsible Officer of the Trustee has actual knowledge (as determined in accordance with Section 16.11) that such payment or distribution is prohibited by this ARTICLE XVI.

With respect to the holders of Guarantor Senior Debt of each Guarantor, the Trustee undertakes to perform only such obligations on the part of the Trustee as are specifically set forth in this ARTICLE XVI, and no implied covenants or obligations with respect to such holders of Guarantor Senior Debt shall be read into this Indenture against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to such holders of Guarantor Senior Debt, and shall not be liable to any such holders if the Trustee shall pay over or distribute to or on behalf of holders of Securities or a Guarantor or any other person money or assets to which any such holders of Guarantor Senior Debt shall be entitled by virtue of this ARTICLE XVI, except if such payment or distribution is made as a result of the willful misconduct or negligence of the Trustee.

Section 16.6 Notice by Guarantors.

Each Guarantor shall promptly notify the Trustee of any facts known to such Guarantor that would cause a payment of any obligations of such Guarantor with respect to the Securities to violate this ARTICLE XVI, but failure to give such notice shall not affect the subordination of the Guarantees of such Guarantor to the Guarantor Senior Debt of such Guarantor as provided in this ARTICLE XVI.

Section 16.7 Subrogation.

After all Guarantor Senior Debt of a Guarantor is paid in full and until the Guarantee of such Guarantor has been fully discharged, Holders of Securities shall be subrogated (equally and ratably with all other indebtedness pari passu with the Guarantees) to the rights of holders of Guarantor Senior Debt of such Guarantor to receive distributions applicable to Guarantor Senior Debt of such Guarantor to the extent that distributions otherwise payable to the Holders of Securities have been applied to the payment of such Guarantor Senior Debt of such Guarantor. A distribution made under this ARTICLE XVI to holders of such Guarantor Senior Debt that otherwise would have been made to Holders of Securities is not, as between such Guarantor and Holders of Securities, a payment by the Guarantor on such Guarantor’s Guarantee.

II-B-70

Section 16.8 Relative Rights.

This Article XVI defines the relative rights of Holders of Securities under the Guarantees of a Guarantor and holders of Guarantor Senior Debt of such Guarantor. In no event shall payments by the Company, or claims of any Holder against the Company in respect of the Securities or under this Indenture be subject to the provisions of this ARTICLE XVI. Nothing contained in this Indenture shall otherwise:

(1) impair, as between the Guarantors and Holders of Securities, the obligation of the Guarantors, which are absolute and unconditional, under the Guarantees;

(2) affect the relative rights of Holders of Securities and creditors (other than with respect to Guarantor Senior Debt of the Guarantors) of the Guarantors, other than their rights in relation to holders of such Guarantor Senior Debt of such Guarantors; or

(3) prevent the Trustee or any Holder of Securities from exercising its available remedies under any Guarantee upon a Default or Event of Default, subject to the notice requirements of Section 8.2 and to the rights of holders and owners of Guarantor Senior Debt of the Guarantors to receive distributions and payments otherwise payable to Holders of Securities as provided in this ARTICLE XVI.

Section 16.9 Subordination May Not Be Impaired by Guarantors.

No right of any holder of Guarantor Senior Debt of the Guarantors to enforce the subordination of the indebtedness evidenced by the Guarantees shall be impaired by any act or failure to act by any Guarantor or any Holder of Securities or by the failure of any Guarantor or any such Holder to comply with this Indenture.

Section 16.10 Distribution or Notice to Representative.

Whenever a distribution is to be made or a notice given to holders of Guarantor Senior Debt of a Guarantor, the distribution may be made and the notice given to their representative(s).

Upon any payment or distribution of assets of a Guarantor referred to in this Article XVI, the Trustee and the Holders of Securities shall be entitled to rely upon any order or decree made by any court of competent jurisdiction or upon any certificate of such Representative or of the liquidating trustee or agent or other person making any distribution to the Trustee or to the Holders of Securities for the purpose of ascertaining the persons entitled to participate in such distribution, the holders of the Guarantor Senior Debt and other indebtedness of any Guarantor, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article XVI.

Section 16.11 Rights of Trustee and Paying Agent.

Each Guarantor shall give prompt written notice to the Trustee of any fact known to the Guarantor that would prohibit the making by such Guarantor of any payment to or by the Trustee in respect of its Guarantee. Notwithstanding the provisions of this Article XVI or any other provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts that would prohibit the making of any payment or distribution by a Guarantor (other than pursuant to Section 16.4) unless a Responsible Officer shall have received at least two business days prior to the date of such payment or distribution written notice of facts that would cause such payment or distribution with respect to a Guarantee to violate this Article XVI. Only a Guarantor or the holder or representative of any class of Guarantor Senior Debt of a Guarantor may give such notice.

Nothing contained in this Article XVI shall impair the claims of, or payments to, the Trustee under or pursuant to Section 9.7.

The Trustee in its individual or any other capacity may hold Guarantor Senior Debt of one or more Guarantors with the same rights it would have if it were not Trustee. Any agent of the Company or any Guarantor may do the same with like rights.

II-B-71

Section 16.12 Authorization to Effect Subordination.

Each Holder of a Security by such Holder’s acceptance thereof authorizes and directs the Trustee on the holder’s behalf to take such action as may be necessary or appropriate to effectuate the subordination as provided in this Article XVI, and appoints the Trustee to act as the holder’s attorney-in-fact for any and all such purposes. If the Trustee does not file a proper proof of claim or proof of debt in the form required in any proceeding referred to in Section 8.9 at least 30 days before the expiration of the time to file such claim, the holders of any Guarantor Senior Debt of a Guarantor or their representatives are hereby authorized to file an appropriate claim for and on behalf of the Holders of the Securities.

Section 16.13 Article Applicable to Paying Agents.

In case at any time any Paying Agent other than the Trustee shall have been appointed by the Company and be then acting hereunder, the term “Trustee” as used in this Article shall in such case (unless the context otherwise requires) be construed as extending to and including such Paying Agent within its meaning as fully for all intents and purposes as if such Paying Agent were named in this Article in addition to or in place of the Trustee.

Section 16.14 Guarantor Senior Debt Entitled to Rely.

The holders of Guarantor Senior Debt of each Guarantor shall have the right to rely upon this Article XVI, and no amendment or modification of the provisions contained herein shall diminish or adversely affect the rights of such holders of Guarantor Senior Debt outstanding at the time of such amendment or modification unless such holders shall have agreed in writing thereto.

Section 16.15 Permitted Payments.

Notwithstanding anything to the contrary contained in this Article XVI, the Holders of Securities may receive and retain from any Guarantor at any time on or prior to the Stated Maturity securities of such Guarantor that are subordinated to at least the same extent as the Guarantee of such Guarantor to (a) Guarantor Senior Debt of such Guarantor and (b) any securities of such Guarantor issued in exchange for Guarantor Senior Debt of such Guarantor.

Section 16.16 No Waiver of Subordination Provisions.

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

Without in any way limiting the generality of the foregoing paragraph, the holders of Guarantor Senior Debt of any Guarantor may, at any time and from time to time, without the consent of or notice to the Trustee or the Holders of the Securities, without incurring responsibility to the Holders of the Securities and without impairing or releasing the subordination provided in this Article XVI or the obligations hereunder of the Holders of the Securities to the holders of Guarantor Senior Debt of such Guarantor, do any one or more of the following, subject to any rights of such Guarantor in respect thereof: (i) change the manner, place or terms of payment or extend the time of payment of, or renew or alter, Guarantor Senior Debt of such Guarantor, or otherwise amend or supplement in any manner such Guarantor Senior Debt or any instrument evidencing the same or any agreement under which such Guarantor Senior Debt is outstanding; (ii) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing such Guarantor Senior Debt; (iii) release any person liable in any manner for the collection of such Guarantor Senior Debt; and (iv) exercise or refrain from exercising any rights against such Guarantor and any other person.

II-B-72

Section 16.17 Trustee Not Fiduciary for Holders of Guarantor Senior Indebtedness.

The Trustee shall not be deemed to owe any fiduciary duty to the holders of Guarantor Senior Indebtedness and shall not be liable to any such holders if the Trustee shall be in good faith mistakenly pay over or distribute to Holders of Securities or to the Company or to any other person cash, property or securities to which any holders of Guarantor Senior Indebtedness shall be entitled buy virtue of this ARTICLE XVI or otherwise. With respect to the holders of Guarantor Senior Indebtedness, the Trustee undertakes to perform or to observe only such of its covenants or obligations as are specifically set forth in this ARTICLE XVI and no implied covenants or obligations with respect to holders of Guarantor Senior Indebtedness shall be read into this Indenture against the Trustee.

Contingent Interest shall be paid on February 1 in respect of any Contingent Interest Period ended on January 31 and on August 1 in respect of any Contingent Interest Period ended on July 31.

2.0% Convertible Senior Notes due 2024

This Note is one of a duly authorized issue of 2.0% Convertible Senior Notes due 2024 (the “Notes”) of COMTECH TELECOMMUNICATIONS CORP., a Delaware corporation (including any successor corporation under the Indenture hereinafter referred to, the “Company”), issued under an Indenture, dated as of January 27, 2004 (the “Indenture”), among the Company, the guarantors parties thereto (the “Guarantors”) and THE BANK OF NEW YORK, a New York banking corporation, as Trustee (the “Trustee”). The terms of the Note include those stated in the Indenture, those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (“TIA”), and those set forth in this Note. This Note is subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of all such terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Note and the terms of the Indenture, the terms of the Indenture shall control. Capitalized terms used but not defined herein have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

1. Interest.

Interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day months.

If this Note is redeemed pursuant to Section 5 of this Note or the Holder elects to require the Company to purchase this Note pursuant to Section 6 of this Note, on a date that is after the Regular Record Date and on or before the corresponding Interest Payment Date, interest, Contingent Interest and Additional Interest, if any, accrued and unpaid hereon to, but excluding, the applicable Redemption Date, Purchase Date or Fundamental Change Purchase Date shall be paid to the same Holder to whom the Company pays the principal of this Note. Interest, Contingent Interest and Additional Interest, if any, accrued and unpaid hereon at the Stated Maturity also shall be paid to the same Holder to whom the Company pays the principal of this Note.

Interest, Contingent Interest and Additional Interest, if any, on Notes converted after the close of business on a Regular Record Date but prior to the opening of business on the corresponding Interest Payment Date shall be paid to the Holder of the Notes on the Regular Record Date but, upon conversion, the Holder must pay the Company an amount equal to the interest, Contingent Interest and Additional Interest, if any, which has accrued and shall be paid on such Interest Payment Date. No such payment need be made with respect to Notes converted after a Regular Record Date and prior to the corresponding Interest Payment Date after being called for redemption or upon acceleration.

All references herein to interest accrued or payable as of any date shall, without duplication, be deemed to include Contingent Interest and Additional Interest, if any, payable pursuant to the Registration Rights Agreement.

2. Method of Payment.

Payment of the principal of and interest on the Notes shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. The Holder must surrender the Notes to the Paying Agent to collect payment of principal. Payment of interest on Certificated Securities in the aggregate Principal Amount at Issuance of $5,000,000 or less shall be made by check mailed to the address of the Person entitled thereto as such address appears in the Register, and payment of interest on Certificated Securities in aggregate Principal Amount at Issuance in excess of $5,000,000 shall be made by wire transfer in immediately available funds at the election of such Holder. Notwithstanding the foregoing, so long as the Notes are registered in the name of a Depositary or its nominee, all payments with respect to the Notes shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee. At the Stated Maturity, interest, Contingent Interest and Additional Interest, if any, on Certificated Securities will be payable at the office or agency of the Company described in the Indenture.

II-B-86

3. Paying Agent, Registrar, Conversion Agent.

Initially, The Bank of New York shall act as Paying Agent, Registrar and Conversion Agent. The Company may appoint and change any Paying Agent, Registrar and Conversion Agent without notice, other than notice to the Trustee; provided that the Company shall maintain at least one Paying Agent in the Borough of Manhattan, New York, New York, which shall initially be an office or agency of the Trustee.

4. Indenture.

The Notes are general senior obligations of the Company limited to up to $105,000,000 aggregate Principal Amount at Issuance. The Indenture does not limit other indebtedness of the Company or the Guarantors, secured or unsecured.

5. Redemption of the Notes by the Company.

Subject to the terms and conditions of the Indenture, the Company may, at its option, redeem for cash all or a portion of the Notes at any time (i) during the period commencing on February 4, 2009 to and including January 31, 2010, at a Redemption Price equal to 100.571% of the Accreted Principal Amount of the Notes plus accrued and unpaid interest, Contingent Interest and Additional interest, if any, to, but not including, the Redemption Date; (ii) during the period commencing on February 1, 2010 to and including January 31, 2011, at a Redemption Price equal to 100.286% of the Accreted Principal Amount of the Notes plus accrued and unpaid interest, Contingent Interest and Additional Interest, if any, to, but not including, the Redemption Date; and (iii) beginning on February 1, 2011, at a Redemption Price equal to 100% of the Accreted Principal Amount of the Notes plus accrued and unpaid interest, Contingent Interest and Additional Interest, if any, to, but not including, the Redemption Date.

At least 20 calendar days but not more than 60 calendar days before a Redemption Date, the Company shall mail a notice of redemption by first-class mail, postage prepaid, to each Holder of Notes to be redeemed. Once notice of redemption is given, Notes called for redemption become due and payable on the Redemption Date and at the Redemption Price, except for Notes which are converted in accordance with the terms of this Indenture. Upon surrender to the Paying Agent, such Notes shall be paid at the Redemption Price. If the Paying Agent holds, in accordance with the terms hereof, at 10:00 a.m., New York City time, on the applicable Redemption Date, cash sufficient to pay the Redemption Price of any Notes for which notice of redemption is given, then, on such Redemption Date, such Notes shall cease to be outstanding and interest, Contingent Interest and Additional Interest, if any, on such Notes shall cease to accrue, whether or not such Notes are delivered to the Paying Agent, and the rights of the Holders in respect thereof shall terminate (other than the right to receive the Redemption Price upon delivery of such Notes).

6. Purchase by the Company at the Option of the Holder on Specific Dates; Purchase at the Option of the Holder Upon a Fundamental Change.

Each Holder shall have the right, at the Holder’s option, but subject to the provisions of the Indenture, to require the Company to purchase all of such Holder’s Notes not theretofore called for redemption, or any portion of the Principal Amount at Issuance thereof that is equal to $1,000 or an integral multiple thereof, on each of February 1, 2011, February 1, 2014 and February 1, 2019. The Company shall be required to purchase such Notes at a purchase price in cash equal to 100% of the Accreted Principal Amount plus accrued and unpaid interest, Contingent Interest and Additional Interest, if any, to, but excluding, the Purchase Date. To exercise such right, a Holder shall deliver a Purchase Notice to the Paying Agent at any time from the opening of business on the date that is 22 Business Days prior to the relevant Purchase Date until the close of business on the second Business Day prior to such Purchase Date.

In the event that a Fundamental Change shall occur at any time prior to the Stated Maturity, each Holder shall have the right, at the Holder’s option, but subject to the provisions of the Indenture, to require the Company to purchase all of such Holder’s Notes not theretofore called for redemption, or any portion of the Principal Amount at Issuance thereof that is equal to $1,000 or an integral multiple thereof. The Company shall be

II-B-87

required to purchase such Notes at a purchase price in cash equal to 100% of the Accreted Principal Amount plus any accrued and unpaid interest, Contingent Interest and Additional Interest, if any to, but excluding, the Fundamental Change Purchase Date. To exercise such right, a Holder shall deliver a Fundamental Change Purchase Notice to the Paying Agent at any time on or before the 20th Business Day after the date of the Company’s notice of the Fundamental Change (subject to extension to comply with applicable law).

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

If the Paying Agent holds, in accordance with the terms hereof, at 10:00 a.m., New York City time, on the applicable Purchase Date or Fundamental Change Purchase Date, cash sufficient to irrevocably pay the Purchase Price or Fundamental Change Purchase Price, as the case may be, of any Notes for which a Purchase Price or Fundamental Change Purchase Notice, as the case may be, has been tendered and not withdrawn pursuant to the Indenture, then, on such Purchase Date or Fundamental Change Purchase Date, as the case may be, such Notes shall cease to be outstanding and interest, Contingent Interest and Additional Interest, if any, on such Notes shall cease to accrue, whether or not such Notes are delivered to the Paying Agent, and the rights of the Holders in respect thereof shall terminate (other than the right to receive the Purchase Price or Fundamental Change Purchase Price, as the case may be, upon delivery of such Notes).

7. Conversion.

Subject to and in compliance with the provisions of the Indenture (including, without limitation, the conditions to conversion of this Note set forth in Section 12.1 thereof), a Holder is entitled, at such Holder’s option, to convert the Holder’s Note (or any portion of the Principal Amount at Issuance thereof that is $1,000 or an integral multiple thereof), into fully paid and non-assessable shares of Common Stock at the Conversion Rate in effect on the date of conversion. The number of shares of Common Stock issuable upon conversion of each $1,000 of Principal Amount at Issuance of Notes is initially 21.1640 shares of Common Stock, and is subject to adjustment in certain events as set forth in the Indenture.

Upon conversion, the Company shall have the right to deliver, in lieu of shares of Common Stock, cash or a combination of cash and shares of Common Stock as provided in the Indenture. The Company shall notify Holders of any event triggering the right to convert the Notes as specified in the Indenture in accordance with the Indenture.

With respect to any conversion of a Note during a Registration Default Period following satisfaction of any of the conditions to conversion described in the Indenture (and during the prescribed time periods in respect thereof), a Holder shall be entitled, subject to the Indenture, to 103% of the number of shares of Common Stock that the Holder would have otherwise been entitled to upon conversion in respect of the portion of the Conversion Obligation that the Company settles in Common Stock.

A Note in respect of which a Holder has delivered a Purchase Notice or Fundamental Change Purchase Notice, as the case may be, exercising the right of such Holder to require the Company to purchase such Note may be converted only if such Purchase Notice or Fundamental Change Purchase Notice is withdrawn in accordance with the terms of the Indenture.

Except as described in the Indenture, the Company will not make any payment in cash or Common Stock or other adjustment for accrued and unpaid interest, Contingent Interest or Additional interest on any Notes when they are converted. The Company’s delivery to the Holder of the full number of shares of Common Stock into which the Note is convertible (or, at the Company’s option, cash, or a combination of cash and Common Stock, in lieu thereof as provided in the Indenture), together with any cash payment for such Holder’s fractional shares, shall be deemed to satisfy the Company’s obligation to pay the Accreted Principal Amount of the Note and to satisfy its obligation to pay accrued and unpaid interest, Contingent Interest and Additional Interest, if any through the conversion date. As a result, accrued interest, Contingent Interest and Additional Interest are deemed paid in full rather than cancelled, extinguished or forfeited. Notwithstanding the foregoing, accrued interest, Contingent Interest and Additional Interest, if any, will be payable upon any conversion of Notes made concurrently with or after acceleration of the Notes following an Event of Default.

II-B-88

Before any Holder shall be entitled to convert any Notes into Common Stock, such Holder shall, in the case of Global Securities, comply with the Applicable Procedures of the Depositary in effect at that time, and in the case of Certificated Securities, surrender such Securities, duly endorsed to the Company or in blank, at the office of the Conversion Agent, and shall give written notice to the Company at said office or place in the form of the Conversion Notice attached to the Note that such Holder elects to convert the same and shall state in writing therein the Principal Amount at Issuance of Notes to be converted (in whole or in part so long as the Principal Amount at Issuance to be converted is in multiples of $1,000) and the name or names (with addresses) in which such Holder wishes the certificate or certificates for Common Stock to be issued. Before any such conversion, a Holder also shall pay all funds required, if any, relating to interest, Contingent Interest or Additional Interest, if any, on the Notes, as provided in the Indenture, and all taxes or duties, if any, as provided in the Indenture.

If the Company (i) reclassifies the Common Stock, (ii) is a party to a consolidation, merger or binding share exchange or (iii) conveys, transfers or leases all or substantially all of its properties and assets to any Person, the right to convert a Note into shares of Common Stock may be changed into a right to convert it into securities, cash or other assets of the Company or such other Person, in each case in accordance with the Indenture.

8. Denominations; Transfer; Exchange.

The Notes shall be issued in fully registered form, without coupons, in denominations of $1,000 of Principal Amount at Issuance and integral multiples thereof. A Holder may transfer or exchange Notes in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. Neither the Company, the Registrar nor the Trustee shall be required to exchange or register a transfer of (i) any Notes selected for redemption (except, in the case of Notes to be redeemed in part, the portion thereof not to be redeemed), or (ii) any Notes in respect of which a Purchase Notice or a Fundamental Change Purchase Notice has been given and not withdrawn by the Holder thereof in accordance with the terms of this Indenture (except, in the case of Notes to be repurchased in part, the portion thereof not to be repurchased), or (iii) any Notes surrendered for conversion (except, in the case of Notes to be converted in part, the portion thereof not to be converted).

9. Persons Deemed Owners.

The registered Holder of this Note may be treated as the owner of this Note for all purposes.

10. Unclaimed Money or Securities.

The Trustee and the Paying Agent shall return to the Company upon written request any cash or securities held by them for the payment of any amount with respect to the Notes that remains unclaimed for two years, subject to applicable unclaimed property law. After return to the Company, Holders entitled to the money or securities must look to the Company for payment as general creditors unless an applicable abandoned property law designates another person.

The Company and the Trustee may amend the Indenture or the Notes without the consent of any Holder to (a) add to the covenants of the Company or those of the Guarantors for the benefit of the Holders of Notes; (b) surrender any right or power herein conferred upon the Company or the Guarantors; (c) provide for conversion rights of Holders of Notes if any reclassification or change of the Common Stock or any consolidation, merger or sale of all or substantially all of the Company’s assets occurs; (d) provide for the assumption of the Company’s obligations to the Holders of Notes in the case of a merger, consolidation, conveyance, transfer, sale, lease or other disposition pursuant to Article VII of the Indenture; (e) increase the Conversion Rate; provided,

II-B-89

however, that such increase in the Conversion Rate shall not adversely affect the interests of the Holders of Notes (after taking into account tax and other consequences of such increase); (f) require the Company to settle its Conversion Obligation in cash with respect to the principal amount of Notes surrendered for conversion; (g) comply with the requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA; (h) make any changes or modifications necessary in connection with the registration of the Notes under the Securities Act as contemplated in the Registration Rights Agreement; provided, however, that such action pursuant to this clause (i) does not, in the good faith opinion of the Board of Directors (as evidenced by a Board Resolution), adversely affect the interests of the Holders of Notes in any material respect; (j) cure any ambiguity, correct or supplement any provision in the Indenture which may be inconsistent with any other provision therein or which is otherwise defective, or to make any other provisions with respect to matters or questions arising under the Indenture which the Company may deem necessary or desirable and which shall not be inconsistent with the provisions of the Indenture; provided, however, that such action pursuant to this clause (j) does not, in the good faith opinion of the Board of Directors (as evidenced by a Board Resolution), adversely affect the interests of the Holders of Notes in any material respect; (k) to evidence the succession of another Person to the Company or any other obligor upon the Notes, and the assumption by any such successor of the covenants of the Company or any Guarantor or such obligor herein and in the Notes, in each case in compliance with the provisions of this Indenture; (l) to evidence and provide the acceptance of the appointment of a successor trustee hereunder; or (m) add Guarantees with respect to the Notes; or (n) add or modify any other provisions herein with respect to matters or questions arising hereunder which the Company and the Trustee may deem necessary or desirable and which shall not adversely affect the interests of the Holders of Notes.

12. Defaults and Remedies.

If any Event of Default, other than as a result of certain events of bankruptcy, insolvency or reorganization of the Company as specified in the Indenture, occurs and is continuing, the Accreted Principal Amount of all the Notes may be declared due and payable in the manner and with the effect provided in the Indenture. If an Event of Default occurs as a result of certain events of bankruptcy, insolvency or reorganization of the Company as provided in the Indenture, the Accreted Principal Amount of all the Notes shall become due and payable immediately without any declaration or other act on the part of the Trustee or any Holder, all as and to the extent provided in the Indenture.

13. Trustee Dealings with the Company.

Subject to certain limitations imposed by the TIA, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee.

14. Calculations in Respect of Notes.

The Company or its agents shall be responsible for making all calculations called for under ARTICLE XII and ARTICLE XIII of the Indenture, including, but not limited to, determination of the Closing Sale Price of Applicable Stock, the Note Price, the number of shares of Common Stock or other Applicable Stock and/or the amount of cash issuable or payable upon conversion and the amounts of interest, Contingent Interest and Additional Interest, if any, on the Notes. Any calculations made in good faith and without manifest error shall be final and binding on Holders of the Notes. The Company or its agents shall be required to deliver to the Trustee a schedule of its calculations and the Trustee shall be entitled to conclusively rely upon the accuracy of such calculations without independent verification.
