(5) The Company shall not be required: (A) to issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business 15 days before the day of any selection of Notes for redemption under Section 3.02 hereof and ending at the close of business on the day of selection; (B) to register the transfer of or to exchange any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part; or 19 (C) to register the transfer of or to exchange a Note between a record date and the next succeeding interest payment date. (6) Prior to due presentment for the registration of a transfer of any Note, the Trustee, any Agent and the Company may deem and treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and interest on such Notes and for all other purposes, and none of the Trustee, any Agent or the Company shall be affected by notice to the contrary. (7) The Trustee shall authenticate Global Notes and Definitive Notes in accordance with the provisions of Section 2.02 hereof. (8) All certifications, certificates and Opinions of Counsel required to be submitted to the Registrar pursuant to this Section 2.06 to effect a registration of transfer or exchange may be submitted by facsimile. Section 2.07 Replacement Notes. If any mutilated Note is surrendered to the Trustee or the Company and the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Note, the Company shall issue and the Trustee, upon receipt of an Authentication Order, shall authenticate a replacement Note if the Trustee's requirements hereunder are met. If required by the Trustee or the Company, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Company may charge the applicable Holder for its expenses in replacing a Note. Every replacement Note is an additional obligation of the Company and shall be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder. Section 2.08 Outstanding Notes. The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section as not outstanding. Except as set forth in Section 2.09 hereof, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note. If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser. If the principal amount of any Note is considered paid under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue. If the Paying Agent (other than the Company, a Subsidiary or an Affiliate of any thereof) holds, on a redemption date or maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes shall be deemed to be no longer outstanding and shall cease to accrue interest. 20 Section 2.09 Treasury Notes. In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company, shall be considered as though not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes that the Trustee knows are so owned shall be so disregarded. Section 2.10 Temporary Notes. Until certificates representing Notes are ready for delivery, the Company may prepare and the Trustee, upon receipt of an Authentication Order, shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of certificated Notes but may have variations that the Company considers appropriate for temporary Notes and as may be reasonably acceptable to the Trustee. Without unreasonable delay, the Company shall prepare and the Trustee shall, upon receipt of an Authentication Order, authenticate definitive Notes in exchange for temporary Notes. Holders of temporary Notes shall be entitled to all of the benefits of this Indenture. Section 2.11 Cancellation. The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and shall destroy canceled Notes in accordance with its customary practices (subject to the record retention requirement of the Exchange Act). Certification of the destruction of all canceled Notes shall be delivered to the Company. The Company may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation. Section 2.12 Defaulted Interest. If the Company defaults in a payment of interest on the Notes, it shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01 hereof. The Company shall notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Company shall fix or cause to be fixed each such special record date and payment date, provided that no such special record date may be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Company (or, upon the written request of the Company, the Trustee in the name and at the expense of the Company) shall mail or cause to be mailed to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid. 21 ARTICLE 3. REDEMPTION AND PREPAYMENT Section 3.01 Notices to Trustee. If the Company elects to redeem the Notes pursuant to the optional redemption provisions of Section 3.07 hereof, it must furnish to the Trustee, at least 30 days but not more than 60 days before a redemption date, an Officer's Certificate setting forth: (1) the clause of this Indenture pursuant to which the redemption shall occur; (2) the redemption date; (3) the principal amount of Notes to be redeemed; and (4) the redemption price. Section 3.02 Selection of Notes to Be Redeemed or Purchased. If less than all of the Notes are to be redeemed or purchased in an offer to purchase at any time, the Trustee shall select Notes for redemption or purchase as follows: (1) if the Notes are listed on any national securities exchange, in compliance with the requirements of the principal national securities exchange on which the Notes are listed; or (2) if the Notes are not listed on any national securities exchange, on a pro rata basis, by lot or by such method as the Trustee shall deem fair and appropriate. In the event of partial redemption or purchase by lot, the particular Notes to be redeemed or purchased shall be selected, unless otherwise provided herein, not less than 30 nor more than 60 days prior to the redemption or purchase date by the Trustee from the outstanding Notes not previously called for redemption or purchase. The Trustee shall promptly notify the Company in writing of the Notes selected for redemption or purchase and, in the case of any Note selected for partial redemption or purchase, the principal amount thereof to be redeemed or purchased. Notes and portions of Notes selected shall be in amounts of $1,000 or whole multiples of $1,000; except that if all of the Notes of a Holder are to be redeemed or purchased, the entire outstanding amount of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed or purchased. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption or purchase also apply to portions of Notes called for redemption or purchase. Section 3.03 Notice of Optional Redemption. At least 30 days but not more than 60 days before a redemption date, the Company shall mail or cause to be mailed, by first class mail, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture pursuant to Articles 8 or 11, respectively, of this Indenture. 22 The notice shall identify the Notes to be redeemed and shall state: (1) the redemption date; (2) the redemption price; (3) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the redemption date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion shall be issued upon cancellation of the original Note; (4) the name and address of the Paying Agent; (5) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price; (6) that, unless the Company defaults in making such redemption payment, interest on Notes called for redemption ceases to accrue on and after the redemption date; (7) the paragraph of the Notes and/or Section of this Indenture pursuant to which the Notes called for redemption are being redeemed; and (8) that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes. At the Company's request, the Trustee shall give the notice of redemption in the Company's name and at its expense; provided, however, that the Company has delivered to the Trustee, at least 45 days prior to the redemption date, an Officer's Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph. Section 3.04 Effect of Notice of Optional Redemption. Once notice of redemption is mailed by the Company in accordance with Section 3.03 hereof, Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price. A notice of redemption may not be conditional. Section 3.05 Deposit of Redemption or Purchase Price. Not less than one Business Day prior to the redemption or purchase price date, the Company shall deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase price of and accrued interest on all Notes to be redeemed or purchased on that date. The Trustee or the Paying Agent shall promptly return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption or purchase price of, and accrued interest on, all Notes to be redeemed or purchased. If the Company complies with the provisions of the preceding paragraph, on and after the redemption or purchase date, interest shall cease to accrue on the Notes or the portions of Notes called for redemption or purchase. If a Note is redeemed or purchased on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest (and Liquidated Damages, if any) shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption or purchase is not so paid upon surrender for 23 redemption or purchase because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption or purchase date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01 hereof. Section 3.06 Notes Redeemed or Purchased in Part. Upon surrender of a Note that is redeemed or purchased in part, the Company shall issue and, upon receipt of an Authentication Order, the Trustee shall authenticate for the Holder at the expense of the Company a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered. Section 3.07 Optional Redemption. At any time on or after November 22, 2009, the Company may redeem the Notes, in whole at any time, or in part from time to time, at a price equal to 100% of the aggregate principal amount of the Notes being redeemed plus accrued and unpaid interest (and Liquidated Damages, if any) up to but not including the date of redemption, payable to the Holders in cash. Any redemption pursuant to this Section 3.07 shall be made pursuant to the provisions of Section 3.01 through 3.06 hereof. Section 3.08 Mandatory Redemption. The Company shall not be required to make mandatory redemption or sinking fund payments with respect to the Notes. Section 3.09 Purchase of Notes at Option of the Holder. (a) General. All or any portion of the Notes held by any Holder shall be purchased by the Company at the option of the Holder on November 15, 2009, November 15, 2013 and November 15, 2018 (each a "Purchase Date"), at a price equal to 100% of the aggregate principal amount of the Notes being purchased plus accrued and unpaid interest (and Liquidated Damages, if any) to the applicable Purchase Date (the "Purchase Price"). Purchases of Notes hereunder shall be made, at the option of the Holder thereof, upon: (1) delivery to the Paying Agent by the Holder of a written notice of purchase (a "Purchase Notice") at any time from the opening of business on the date that is 20 Business Days prior to a Purchase Date until the close of business on the last Business Day prior to such Purchase Date stating: (a) if certificated Notes have been issued, the certificate number of the Note which the Holder will deliver to be purchased, or if not certificated, the notice must comply with the Applicable Procedures, (b) the portion of the principal amount of the Note which the Holder will deliver to be purchased, which portion must be in principal amounts of $1,000 or an integral multiple thereof, (c) that such Note shall be purchased as of the Purchase Date pursuant to the terms and conditions specified in this Section 3.09, and 24 (d) in the event the Company elects, pursuant to Section 3.09(b), to pay the Purchase Price, in whole or in part, in shares of Common Stock but such portion of the Purchase Price shall ultimately be payable to such Holder entirely in cash because any of the conditions to payment of the Purchase Price in shares of Common Stock is not satisfied prior to the close of business on the Purchase Date, as set forth below, whether such Holder elects (x) to withdraw such Purchase Notice as to some or all of the Notes to which such Purchase Notice relates (stating the principal amount and certificate numbers, if any, of the Notes as to which such withdrawal shall relate), or (y) to receive cash in respect of the entire Purchase Price for all Notes (or portions thereof) to which such Purchase Notice relates; and (2) delivery of such Note to the Paying Agent prior to, on or after the Purchase Date (together with all necessary endorsements) at the offices of the Paying Agent, such delivery being 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 3.09 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. If Global Notes are outstanding, such notice and tender of such Notes must comply with Applicable Procedures. If a Holder, in such Holder's Purchase Notice and in any written notice of withdrawal delivered by such Holder pursuant to the terms of Section 3.11, fails to indicate such Holder's choice with respect to the election set forth in clause (d) of Section 3.09(a)(1), such Holder shall be deemed to have elected to receive cash in respect of the entire Purchase Price for all Notes subject to such Purchase Notice in the circumstances set forth in such clause (d). The Company shall purchase from the Holder thereof, pursuant to this Section 3.09, a portion of a Note if the principal amount of such portion is $1,000 or an integral multiple of $1,000. Provisions of this Indenture that apply to the purchase of all of a Note also apply to the purchase of such portion of such Note. Any purchase by the Company contemplated pursuant to the provisions of this Section 3.09 shall be consummated by the delivery of the consideration to be received by the Holder promptly following the later of (x) the Purchase Date and (y) the time of delivery of the Note. Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Purchase Notice contemplated by this Section 3.09(a) shall have the right to withdraw such Purchase Notice at any time prior to the close of business on the Business Day preceding the Purchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 3.11. The Paying Agent shall promptly notify the Company of the receipt by it of any Purchase Notice or written notice of withdrawal thereof. (b) Company's Right to Elect Manner of Payment of Purchase Price for Payment. The Notes to be purchased on any Purchase Date pursuant to Section 3.09(a) may be paid for, at the election of the Company, in cash or shares of Common Stock, or in any combination of cash and shares of Common Stock, subject to the conditions set forth in Section 3.09(c). The Company shall designate, in the Company Notice delivered pursuant to Section 3.09(d), which shall be sent to Holders (and to beneficial owners as required by applicable law) not less than 20 Business Days prior to the Purchase Date (the "Company Notice Date"), whether the Company will purchase the Notes for cash or shares of Common Stock, or, if a combination thereof, the percentages of the Purchase Price of Notes in respect of which it will pay in cash and shares of Common Stock; provided, however, that the Company will pay cash for fractional shares of Common Stock. For purposes of determining the existence of potential 25 fractional shares, all Notes subject to purchase by the Company held by a Holder shall be considered together (no matter how many separate certificates are to be presented). Each Holder whose Notes are purchased pursuant to this Section 3.09 shall receive the same percentage of cash or shares of Common Stock in payment of the Purchase Price for such Notes, except (i) as provided in Section 3.09(c) with regard to the payment of cash in lieu of fractional shares of Common Stock and (ii) in the event that the Company is unable to purchase the Notes of a Holder or Holders for shares of Common Stock because any necessary qualifications or registrations of the shares of Common Stock under applicable state securities laws cannot be obtained, the Company may purchase the Notes of such Holder or Holders for cash. The Company may not change its election with respect to the consideration (or components or percentages of components thereof) to be paid once the Company has given its Company Notice to Holders of Notes except pursuant to this Section 3.09(b) or pursuant to Section 3.09(c) in the event of a failure to satisfy, prior to the close of business on the Purchase Date, any condition to the payment of the Purchase Price, in whole or in part, in Common Stock. At least three Business Days before the Company Notice Date, the Company shall deliver an Officer's Certificate to the Trustee specifying: (1) the manner of payment selected by the Company; (2) the information required by Section 3.09(d); (3) if the Company elects to pay the Purchase Price, or a specified percentage thereof, in Common Stock, that the conditions to such manner of payment set forth in Section 3.09(c) have been or will be complied with; and (4) whether the Company desires the Trustee to give the Company Notice required by Section 3.09(d). Simultaneously with the delivery of the Company Notice to Holders, the Company shall, or, if the Company has requested that Trustee deliver the Company Notice to Holders pursuant to this Section 3.09(b), shall cause the Trustee to, at the Company's expense and in the Company's name, disseminate a press release through any of Dow Jones & Company, Inc., Business Wire, Bloomberg Business News or Reuters (or if such organizations are not in existence at the time of issuance of such press release, such other news or press organization as is reasonably calculated to broadly disseminate the relevant information to the public) containing this information, and the Company shall publish the information on the Company's Web site on the World Wide Web or through such other public medium as the Company may use at that time. (c) Payment by Issuance of Shares of Common Stock. At the option of the Company, the Purchase Price of Notes in respect of which a Purchase Notice pursuant to Section 3.09(a) has been given, or a specified percentage thereof, may be paid by the Company by the issuance of a number of shares of Common Stock equal to the quotient obtained by dividing (i) the amount of cash to which the Holders of Notes would have been entitled had the Company elected to pay all or such specified percentage, as the case may be, of the Purchase Price of such Notes in cash by (ii) the Market Price of one share of Common Stock, subject to the next succeeding paragraph. The Company will not issue a fractional shares of Common Stock in payment of the Purchase Price. Instead the Company will pay cash for the current Market Price of the fractional share. The current Market Price of a fraction of a share shall be determined by the Company by multiplying the Market Price by such fraction and rounding the product to the nearest whole cent with one-half cent being rounded 26 upward. It is understood that if a Holder elects to have more than one Note purchased, the number of shares of Common Stock shall be based on the aggregate amount of Notes to be purchased. If the Company elects to purchase the Notes by the issuance of shares of Common Stock, the Company Notice, as provided in Section 3.09(d), shall be sent to the Holders (and to beneficial owners as required by applicable law) not later than the Company Notice Date. The Company's right to exercise its election to purchase Notes through the issuance of shares of Common Stock shall be conditioned upon: (1) the Company's not having given its Company Notice of an election to pay entirely in cash and its giving of timely Company Notice of election to purchase all or a specified percentage of the Notes with shares of Common Stock as provided herein; (2) the registration of such shares of Common Stock under the Securities Act, or the Exchange Act, in each case, if required; (3) such shares of Common Stock having been listed on the principal national securities exchange (currently The New York Stock Exchange) on which the Common Stock is listed; (4) any necessary qualification or registration under applicable state securities laws or the availability of an exemption from such qualification and registration; and (5) the receipt by the Trustee of an Officer's Certificate stating that (A) the terms of the issuance of the shares of Common Stock are in conformity with this Indenture and (B) the shares of Common Stock to be issued by the Company in payment of the Purchase Price in respect of Notes have been duly authorized and, when issued and delivered pursuant to the terms of this Indenture in payment of the Purchase Price in respect of the Notes, will be validly issued, fully paid and non-assessable and free from preemptive rights, and stating that the conditions above and the condition set forth in the second succeeding sentence have been satisfied. Such Officer's Certificate shall also set forth (i) the number of shares of Common Stock to be issued for each $1,000 principal amount of Notes, (ii) the Common Stock Price on each Trading Day during the period commencing on the first Trading Day of the period during which the Market Price is calculated and ending on the third Business Day prior to the applicable Purchase Date and (iii) the Market Price of the Common Stock. The Company may pay the Purchase Price (or any portion thereof) in shares of Common Stock only if the information necessary to calculate the Market Price is published in a daily newspaper of national circulation or is otherwise publicly available (e.g., by dissemination on the World Wide Web or by other public means). If the foregoing conditions are not satisfied with respect to a Holder or Holders prior to the close of business on the Purchase Date and the Company has elected to purchase the Notes pursuant to this Section 3.09 through the issuance of shares of Common Stock, the Company shall pay the entire Purchase Price of the Notes of such Holder or Holders in cash. Upon determination of the actual number of shares of Common Stock to be issued for each $1,000 principal amount of Notes, not later than the second Business Day prior to the relevant Purchase Date, the Company will disseminate a press release through any of Dow Jones & Company, Inc., Business Wire, Bloomberg Business News or Reuters (or if such organizations are not in existence at the time of issuance of such press release, such other news or press organization as is reasonably calculated to broadly disseminate the relevant information to the public) containing this information and publish the 27 information on the Company's Web site on the World Wide Web or through such other public medium as the Company may use at that time. (d) Notice of Election. In connection with any purchase of Notes pursuant to this Section 3.09, the Company shall give notice to Holders setting forth information specified in this Section 3.09(d) (the "Company Notice"). In the event the Company has elected to pay the Purchase Price (or a specified percentage thereof) with shares of Common Stock, the Company Notice shall: (1) state that each Holder will receive shares of Common Stock with a Market Price determined as of a specified date prior to the Purchase Date equal to such specified percentage of the Purchase Price of the Notes held by such Holder (except any cash amount to be paid in lieu of fractional shares); (2) set forth the method of calculating the Market Price of the shares of Common Stock; and (3) state that because the Market Price of shares of Common Stock will be determined prior to the Purchase Date, Holders will bear the market risk with respect to the value of the shares of Common Stock to be received from the date such Market Price is determined to the Purchase Date. In any case, each Company Notice shall include a form of Purchase Notice to be completed by a Holder of Notes and shall state: (1) the Purchase Price and the Conversion Price; (2) the name and address of the Paying Agent and the Conversion Agent; (3) that Notes as to which a Purchase Notice has been given may be converted if they are otherwise convertible only in accordance with Article 10 hereof and Paragraph 9 of the Notes if the applicable Purchase Notice has been withdrawn in accordance with the terms of this Indenture; (4) that Notes must be surrendered to the Paying Agent to collect payment; (5) that the Purchase Price for any security as to which a Purchase Notice has been given and not withdrawn will be paid promptly following the later of (x) the Purchase Date and (y) the time of surrender of such Note as described in (4); (6) the procedures the Holder must follow to exercise its rights under Section 3.09 and a brief description of those rights; (7) briefly, the conversion rights of the Notes; (8) the procedures for withdrawing a Purchase Notice (including, without limitation, for a conditional withdrawal pursuant to the terms of Section 3.09(a)(1)(d) or Section 3.11); 28 (9) that, unless the Company defaults in making payment on Notes for which a Purchase Notice has been submitted, interest on such Notes will cease to accrue on the Purchase Date; and (10) the CUSIP number of the Notes. At the Company's request, the Trustee shall give such Company Notice in the Company's name and at the Company's expense; provided, however, that, in all cases, the text of such Company Notice shall be prepared by the Company. (e) Covenants of the Company. All shares of Common Stock delivered upon purchase of the Notes shall be newly issued shares or treasury shares, shall be duly authorized, validly issued, fully paid and nonassessable, and shall be free from preemptive rights and free of any lien or adverse claim. (f) Procedure upon Purchase. The Company shall deposit cash (in respect of cash purchases under this Section 3.09 or for fractional shares, as applicable) or shares of Common Stock in respect of payment by issuance of shares of Common Stock under Section 3.09(c), except for fractional shares, or a combination thereof, as applicable, at the time and in the manner as provided in Section 3.12, sufficient to pay the aggregate Purchase Price of all Notes to be purchased pursuant to this Section 3.09. As soon as practicable after the Purchase Date, the Company shall deliver to each Holder entitled to receive shares of Common Stock through the Paying Agent a certificate for the number of full shares of Common Stock issuable in payment of the Purchase Price and cash in lieu of any fractional shares. The person in whose name the certificate for shares of Common Stock is registered shall be treated as a holder of record of Common Stock on the Business Day following the Purchase Date. No payment or adjustment will be made for dividends on the shares of Common Stock the record date for which occurred on or prior to the Purchase Date. (g) Taxes. If a Holder of a purchased Note (pursuant to this Section 3.09 or Section 3.10) is paid in shares of Common Stock, the Company shall pay any documentary, stamp or similar issue or transfer tax due on such issue of Common Stock. However, the Holder shall pay any such tax which is due because the Holder requests the Common Stock to be issued in a name other than the Holder's name. The Paying Agent may refuse to deliver the certificates representing the shares of Common Stock being issued in a name other than the Holder's name until the Paying Agent receives a sum sufficient to pay any tax which will be due because the shares of Common Stock are to be issued in a name other than the Holder's name. Nothing herein shall preclude any income tax withholding required by law or regulations. Section 3.10 Purchase of Notes at Option of the Holder upon Change in Control. (a) If a Change in Control occurs, a Holder of Notes will have the right, at its option, to require the Company to repurchase all of its Notes, or any portion of the principal amount thereof at a purchase price equal to (1) the issue price plus any accrued and unpaid interest (and Liquidated Damages, if any) or (2) at the option of the Company, a number of shares of Common Stock as calculated below (the "Change in Control Purchase Price"), as of the date that is 45 days after the date of the Change in Control Notice (as defined below) delivered by the Company (the "Change in Control Purchase Date"), subject to satisfaction by or on behalf of the Holder of the requirements set forth in Section 3.10(c). Notwithstanding the foregoing provisions of this Section 3.10, a Change in Control shall not be deemed to have occurred if: (1) the Common Stock Price on The New York Stock Exchange for any five Trading Days within the period of 10 consecutive Trading Days ending immediately after the later of the 29 event, that, but for this provision, would constitute a Change in Control or the public announcement of such event, in the case of a Change in Control relating to an acquisition of Capital Stock, or the period of 10 consecutive Trading Days ending immediately before such event, in the case of Change in Control relating to a merger, consolidation or asset sale, equals or exceeds 105% of the Conversion Price of the Notes in effect on each of those Trading Days; or (2) all of the consideration (excluding cash payments for fractional shares and cash payments made pursuant to dissenters' appraisal rights) in a merger or consolidation otherwise constituting a Change in Control above consists of shares of common stock traded on a national securities exchange or quoted on the Nasdaq National Market (or will be so traded or quoted immediately following the merger or consolidation) and as a result of the merger or consolidation the Notes become convertible into such common stock. For purposes of this Section 3.10, (x) the Conversion Price is equal to $1,000 divided by the Conversion Rate, (y) whether a person is a "beneficial owner" shall be determined in accordance with Rule 13d-3 under the Exchange Act; and (z) "person" includes any syndicate or group that would be deemed to be a "person" under Section 13(d)(3) of the Exchange Act. If the shares of Common Stock are not listed on The New York Stock Exchange at the relevant time, closing prices and Trading Days shall be calculated as reported by the NASDAQ. At the option of the Company, the Change in Control Purchase Price of Notes in respect of which a Change in Control Purchase Notice pursuant to Section 3.10(c) has been given may be paid by the Company by the issuance of a number of shares of Common Stock equal to the quotient obtained by dividing (i) the product of (A) the amount of cash to which the Holders of Notes would have been entitled had the Company elected to pay all of the Change in Control Purchase Price of such Notes in cash and (B) 0.95, by (ii) the Market Price of shares of Common Stock, subject to the next succeeding paragraph. The Company will not issue fractional shares of Common Stock in payment of the Change in Control Purchase Price. Instead the Company will pay cash for the current Market Price of the fractional share. The current Market Price of a fraction of a share shall be determined by multiplying the Market Price by such fraction and rounding the product to the nearest whole cent, with one-half cent being rounded upward. It is understood that if a Holder elects to have more than one Note purchased, the number of shares of Common Stock shall be based on the aggregate amount of Notes to be purchased. In the event that the Company is unable to purchase the Notes of a Holder or Holders for shares of Common Stock because any necessary qualifications or registrations of the shares of Common Stock under applicable state securities laws cannot be obtained, the Company may purchase the Notes of such Holder or Holders for cash. The Company may not change its election with respect to the consideration to be paid once the Company has given its Change in Control Notice to Holders of Notes except pursuant to this Section 3.10(a) or pursuant to Section 3.10(b) in the event of a failure to satisfy, prior to the close of business on the Change in Control Purchase Date, any condition to the payment of the Change in Control Purchase Price in Common Stock. 30 At least three Business Days before the Change in Control Notice Date (as defined below), the Company shall deliver an Officer's Certificate to the Trustee specifying: (i) the manner of payment selected by the Company; (ii) the information required by Section 3.10(b); (iii) if the Company elects to pay the Change in Control Purchase Price in Common Stock, that the conditions to such manner of payment set forth in this Section 3.10(a) have been or will be complied with; and (iv) whether the Company desires the Trustee to give the Change in Control Notice required by Section 3.10(b). The Company's right to exercise its election to purchase Notes through the issuance of shares of Common Stock shall be conditioned upon: (i) the Company's giving of timely Change in Control Notice to purchase all of the Notes with shares of Common Stock as provided herein; (ii) the registration of such shares of Common Stock under the Securities Act or the Exchange Act, in each case, if required; (iii) such shares of Common Stock having been listed on the principal national securities exchange (currently The New York Stock Exchange) on which the Common Stock is listed; (iv) any necessary qualification or registration under applicable state securities laws or the availability of an exemption from such qualification and registration; and (v) the receipt by the Trustee of an Officer's Certificate stating that (A) the terms of the issuance of the shares of Common Stock are in conformity with this Indenture and (B) the shares of Common Stock to be issued by the Company in payment of the Change in Control Purchase Price in respect of Notes have been duly authorized and, when issued and delivered pursuant to the terms of this Indenture in payment of the Change in Control Purchase Price in respect of the Notes, will be validly issued, fully paid and non-assessable and free from preemptive rights, and stating that the conditions above and the condition set forth in the second succeeding sentence have been satisfied. Such Officer's Certificate shall also set forth (i) the number of shares of Common Stock to be issued for each $1,000 principal amount of Notes, (ii) the Common Stock Price on each Trading Day during the period commencing on the first Trading Day of the period during which the Market Price is calculated and ending on the third Business Day prior to the Change in Control Purchase Date and (iii) the Market Price of the Common Stock. The Company may pay the Change in Control Purchase Price in shares of Common Stock only if the information necessary to calculate the Market Price is published in a daily newspaper of national circulation or is otherwise publicly available (e.g., by dissemination on the World Wide Web or by other public means). If the foregoing conditions are not satisfied with respect to a Holder or Holders prior to the 31 close of business on the Change in Control Purchase Date and the Company has elected to purchase the Notes pursuant to this Section 3.10 through the issuance of shares of Common Stock, the Company shall pay the entire Purchase Price of the Notes of such Holder or Holders in cash. (b) No later than 30 days after the occurrence of a Change in Control, the Company shall mail a written notice of the Change in Control (the "Change in Control Notice" the date of such mailing, the "Change in Control Notice Date") by first-class mail to the Trustee and to each Holder (and to beneficial owners to the extent required by applicable law). The notice shall include a form of Change in Control Purchase Notice to be completed by the Holder that wishes to exercise rights under this Section 3.10 and shall state: (1) briefly, the events causing a Change in Control and the date of such Change in Control; (2) the date by which the Change in Control Purchase Notice pursuant to this Section 3.10 must be given; (3) the Change in Control Purchase Date; (4) the Change in Control Purchase Price; (5) the name and address of the Paying Agent and the Conversion Agent; (6) the Conversion Rate and any adjustments thereto; (7) that Notes must be surrendered to the Paying Agent to collect payment; (8) that the Change in Control Purchase Price for any Note as to which a Change in Control Purchase Notice has been duly given will be paid promptly following the later of (x) the Change in Control Purchase Date and (y) the time of surrender of such Note as described in (7); (9) briefly, the procedures the Holder must follow to exercise rights under this Section 3.10; (10) briefly, the conversion rights, if any, of the Notes; (11) that, unless the Company defaults in making payment of such Change in Control Purchase Price, interest on Notes surrendered for purchase by the Company will cease to accrue on and after the Change in Control Purchase Date; and (12) the CUSIP numbers of the Notes. In the event the Company has elected to pay the Change in Control Purchase Price with shares of Common Stock, the Change in Control Notice shall: (1) state that the Company will pay the Change in Control Purchase Price with shares of Common Stock; (2) set forth the method of calculating the number of shares of Common Stock to be paid; and 32 (3) state that because the Market Price of shares of Common Stock will be determined prior to the Change in Control Purchase Date, Holders will bear the market risk with respect to the value of the shares of Common Stock to be received from the date such Market Price is determined to the Change in Control Purchase Date. Simultaneously with the delivery of the Change in Control Notice to Holders, the Company shall, or, if the Company has requested that Trustee deliver the Company Notice to Holders pursuant to Section 3.10(a), shall cause the Trustee to, at the Company's expense and in the Company's name, disseminate a press release through any of Dow Jones & Company, Inc., Business Wire, Bloomberg Business News or Reuters (or if such organizations are not in existence at the time of issuance of such press release, such other news or press organization as is reasonably calculated to broadly disseminate the relevant information to the public) containing this information, and the Company shall publish the information on the Company's Web site on the World Wide Web or through such other public medium as the Company may use at that time. (c) A Holder may exercise its rights specified in Section 3.10(a) upon delivery of an irrevocable written notice of purchase (a "Change in Control Purchase Notice") to the Paying Agent at any time on or prior to the 30th day after the Company delivers its Change in Control Notice, stating: (1) the certificate number of the Note which the Holder will deliver to be purchased; (2) the portion of the principal amount of the Note which the Holder will deliver to be purchased, which portion must be $1,000 or an integral multiple thereof; and (3) that such Note shall be purchased pursuant to the terms and conditions specified in this Section 3.10. The delivery of such Note to the Paying Agent with the Change in Control Purchase Notice (together with all necessary endorsements) at the offices of the Paying Agent shall be a condition to the receipt by the Holder of the Change in Control Purchase Price therefor; provided, however, that such Change in Control Purchase Price shall be so paid pursuant to this Section 3.10 only if the Note so delivered to the Paying Agent shall conform in all respects to the description thereof set forth in the related Change in Control Purchase Notice. The Company shall purchase from the Holder thereof, pursuant to this Section 3.10, a portion of a Note if the principal amount of such portion is $1,000 or an integral multiple of $1,000. Provisions of this Indenture that apply to the purchase of all of a Note also apply to the purchase of such portion of such Note. Any purchase by the Company contemplated pursuant to the provisions of this Section 3.10 shall be consummated by the delivery of the consideration to be received by the Holder on the Change in Control Purchase Date. (d) All shares of Common Stock delivered upon purchase of the Notes shall be newly issued shares or treasury shares, shall be duly authorized, validly issued, fully paid and nonassessable, and shall be free from preemptive rights and free of any lien or adverse claim. (e) The Company shall deposit cash (in respect of a cash purchases under Section 3.10 or for fractional shares of Common Stock, as applicable) or shares of Common Stock, or a combination thereof, as applicable, at the time and in the manner as provided in Section 3.12, sufficient to pay the aggregate Change in Control Purchase Price of all Notes to be purchased pursuant to this Section 3.10. As soon as practicable after the Change in Control Purchase Date, the Company shall deliver to each Holder entitled 33 to receive shares of Common Stock through the Paying Agent a certificate for the number of full shares of Common Stock issuable in payment of the Change in Control Purchase Price and cash in lieu of any fractional shares. The person in whose name the certificate for shares of Common Stock is registered shall be treated as a holder of record of Common Stock on the Business Day following the Change in Control Purchase Date. No payment or adjustment will be made for dividends on the shares of Common Stock the record date for which occurred on or prior to the Change in Control Purchase Date. Section 3.11 Effect of Purchase Notice or Change in Control Purchase Notice. Upon receipt by the Paying Agent of the Purchase Notice specified in Section 3.09(a) or Change in Control Purchase Notice specified in Section 3.10(c), as applicable, the Holder of the Note in respect of which such Purchase Notice or Change in Control Purchase Notice, as the case may be, was given shall (unless, in the case of the Purchase Notice, such Purchase Notice is withdrawn as specified in the following two paragraphs) thereafter be entitled to receive solely the Purchase Price or Change in Control Purchase Price, as the case may be, with respect to such Note. Such Purchase Price or Change in Control Purchase Price shall be paid to such Holder, subject to receipts of funds and/or securities by the Paying Agent, promptly following the later of (x) the Purchase Date or the Change in Control Purchase Date, as the case may be, with respect to such Note (provided the conditions in Section 3.09(a) or Section 3.10(c), as applicable, have been satisfied) and (y) the time of delivery of such Note to the Paying Agent by the Holder thereof in the manner required by Section 3.09(a) or Section 3.10(c), as applicable.

This will be the case whether or not book-entry transfer of the Notes is made or whether or not the Notes are delivered to the Paying Agent. Notes in respect of which a Purchase Notice or Change in Control Purchase Notice has been given by the Holder thereof may not be converted pursuant to the provisions hereof on or after the date of the delivery of such Purchase Notice or Change in Control Purchase Notice, unless, in the case of the Purchase Notice, such Purchase Notice has first been validly withdrawn as specified in the following two paragraphs. A Purchase Notice may be withdrawn by means of a written notice of withdrawal delivered to the office of the Paying Agent in accordance with the Purchase Notice at any time prior to the close of business on the last Business Day prior to the Purchase Date, specifying: (1) the certificate number, if any, of the Note in respect of which such notice of withdrawal is being submitted, (2) the principal amount of the Note with respect to which such notice of withdrawal is being submitted, and (3) the principal amount, if any, of such Note which remains subject to the original Purchase Notice, and which has been or will be delivered for purchase by the Company. 34 A written notice of withdrawal of a Purchase Notice may be in the form set forth in the preceding paragraph or may be in the form of (i) a conditional withdrawal contained in a Purchase Notice pursuant to the terms of Section 3.09(a)(1)(d) or (ii) a conditional withdrawal containing the information set forth in Section 3.09(a)(1)(d) and the preceding paragraph and contained in a written notice of withdrawal delivered to the Paying Agent as set forth in the preceding paragraph. There shall be no purchase of any Notes pursuant to Section 3.09 or 3.10 if there has occurred (prior to, on or after, as the case may be, the giving, by the Holders of such Notes, of the required Purchase Notice or Change in Control Purchase Notice, as the case may be) and is continuing an Event of Default (other than a default in the payment of the Purchase Price or Change in Control Purchase Price, as the case may be, with respect to such Notes). The Paying Agent will promptly return to the respective Holders thereof any Notes (x) with respect to which a Purchase Notice has been withdrawn in compliance with this Indenture, or (y) held by it during the continuance of an Event of Default (other than a default in the payment of the Purchase Price or Change in Control Purchase Price, as the case may be, with respect to such Notes) in which case, upon such return, the Purchase Notice or Change in Control Purchase Notice with respect thereto shall be deemed to have been withdrawn.

When complying with the provisions of Section 3.09 or 3.10 hereof (provided that such offer or purchase constitutes an "issuer tender offer" for purposes of Rule 13e-4 (which term, as used herein, includes any successor provision thereto) under the Exchange Act at the time of such offer or purchase), the Company shall (i) comply with Rule 13e-4 and Rule 14e-1 (or any successor provision) under the Exchange Act, (ii) file the related Schedule TO (or any successor schedule, form or report) under the Exchange Act, and (iii) otherwise comply with all Federal and state securities laws so as to permit the rights and obligations under Sections 3.09 and 3.10 to be exercised in the time and in the manner specified in Sections 3.09 and 3.10. 35 Section 3.15 Repayment to the Company. The Trustee and the Paying Agent shall return to the Company any cash or shares of Common Stock that remain unclaimed, together with interest or dividends, if any, thereon held by them for the payment of the Purchase Price or Change in Control Purchase Price, as the case may be; provided, however, that to the extent that the aggregate amount of cash or shares of Common Stock deposited by the Company pursuant to Section 3.12 exceeds the aggregate Purchase Price or Change in Control Purchase Price, as the case may be, of the Notes or portions thereof which the Company is obligated to purchase as of the Purchase Date or Change in Control Purchase Date, as the case may be, then, unless otherwise agreed in writing with the Company, promptly after the Business Day following the Purchase Date or Change in Control Purchase Date, as the case may be, the Trustee shall return any such excess to the Company together with interest or dividends, if any, thereon. Prior to such return, any such excess funds held by the Paying Agent shall be invested in cash or Permitted Investments as may be directed by the Company from time to time. ARTICLE 4.

If at any time the Company fails to maintain any such required office or agency or fails to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee. The Company may also from time to time designate one or more other offices or agencies where the 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, the City of New York for such purposes. The Company shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. 36 The Company hereby designates the Corporate Trust Office of the Trustee as one such office or agency of the Company in accordance with Section 2.03 hereof.

Each of the following is an "Event of Default": (1) default for 30 days in payment of any interest installment due and payable on the Notes; (2) default in payment of principal of the Notes and accrued interest at maturity; (3) default in payment of the Purchase Price, when the same becomes due and payable (4) default in payment of the Change in Control Purchase Price, when the same becomes due and payable; (5) material default in the performance of any other covenants or agreements in the Notes or this Indenture which default continues for 30 days after the date on which written notice of such default is given to the Company by the Trustee or to the Company and Trustee by the Holders of at least 25% in principal amount of the then outstanding Notes; (6) default by the Company under any instrument or instruments under which there is or may be secured or evidenced any of the Indebtedness of the Company (other than the Notes) having an outstanding principal amount of $50,000,000 (or its equivalent in any other currency or currencies) or more, individually or in the aggregate, that has caused the holders thereof to declare such indebtedness to be due and payable prior to its Stated Maturity, unless such declaration has been rescinded within 30 days; (7) default by the Company in the payment of the principal of any bond, debenture, note or other evidence of the Company's Indebtedness, in each case for money borrowed, or in the payment of principal under any mortgage, indenture, agreement or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness of the Company for money borrowed, which default for payment of principal is individually or in an aggregate principal amount exceeding $50,000,000 (or its equivalent in any other currency or currencies) when such indebtedness becomes due and payable (whether at maturity, upon redemption or acceleration or otherwise), if such default shall continue unremedied or unwaived for more than 30 days after the expiration of any grace period or extension of the time for payment applicable thereto; and 43 (8) the Company, pursuant to or within the meaning of any Bankruptcy Law: (a) commences a voluntary case; (b) consents to the entry of an order for relief against it in an involuntary case; (c) consents to the appointment of a custodian of it or for all or substantially all of its property; (d) makes a general assignment for the benefit of its creditors; or (e) admits in writing its inability to generally pay its debts as such debts become due; and (9) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: (a) is for relief against the Company in an involuntary case; (b) appoints a custodian of the Company or for all or substantially all of its property; or (c) orders the winding up or liquidation of the Company; and the order or decree remains unstayed and in effect for 60 consecutive days. The Company shall give the Trustee, within 30 days after the occurrence thereof, written notice of any event which with the giving of notice or lapse of time or both would become an Event of Default described in clauses (5), (6) or (7) of this Section 6.01. Section 6.02 Acceleration. (a) In the case of an Event of Default specified in clauses (8) or (9) of Section 6.01 hereof, the issue price plus accrued and unpaid interest (and Liquidated Damages, if any) on the Notes will become immediately due and payable without any action on the part of the Trustee or any Holder. (b) If any other Event of Default occurs and is continuing with respect to the Notes, either the Trustee, by Notice to the Company, or the registered Holders of at least 25% in aggregate principal amount of the Notes, by notice to the Company and the Trustee, may declare the issue price plus accrued and unpaid interest (and Liquidated Damages, if any) on the Notes to be due and payable immediately. At any time after a declaration of acceleration, but before a judgment or decree for payment of money has been obtained, if all Events of Default with respect to the Notes have been cured or waived (other than the nonpayment of the issue price or accrued and unpaid interest (and Liquidated Damages, if any) on the Notes which has become due solely by reason of the declaration of acceleration), then the declaration of acceleration shall be automatically annulled and rescinded. 44 Section 6.03 Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, premium, if any, and interest 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 it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note 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. All remedies are cumulative to the extent permitted by law. Section 6.04 Waiver of Past Defaults. Holders of not less than a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may on behalf of the Holders of all of the Notes waive an existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of the principal of, premium, if any, or interest on, the Notes (including in connection with an offer to purchase); provided, however, that the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon. Section 6.05 Control by Majority. Holders of a majority in principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee in personal liability; provided that the Trustee may take any other lawful action deemed proper by the Trustee that is not inconsistent with such direction. Section 6.06 Limitation on Suits. A Holder of a Note may pursue a remedy with respect to this Indenture or the Notes only if: (1) the Holder of a Note gives to the Trustee written notice of a continuing Event of Default; (2) the Holders of at least 25% in principal amount of the then outstanding Notes make a written request to the Trustee to pursue the remedy; (3) such Holder of a Note or Holders of Notes offer and, if requested, provide to the Trustee indemnity satisfactory to the Trustee against any loss, liability or expense; (4) the Trustee does not comply with the request within 60 days after receipt of the request and the offer and, if requested, the provision of indemnity; and 45 (5) during such 60-day period, the Holders of a majority in principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with the request. A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note. Section 6.07 Rights of Holders of Notes to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal, premium, if any, and interest on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder. Section 6.08 Collection Suit by Trustee. If an Event of Default specified in Section 6.01(1) or (2) occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of principal of, premium, if any, and interest remaining unpaid on the Notes and interest on overdue principal and, to the extent lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. Section 6.09 Trustee May File Proofs of Claim. The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 46 Section 6.10 Priorities. If the Trustee collects any money pursuant to this Article 6, it shall pay out the money in the following order: First: to the Trustee, its agents and attorneys for amounts due under Section 7.07 hereof, including payment of all compensation, expense and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; Second: to Holders of Notes for amounts due and unpaid on the Notes for principal, premium, if any, and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any and interest, respectively; and Third: to the Company or to such party as a court of competent jurisdiction shall direct. The Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 6.10. Section 6.11 Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys' fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in principal amount of the then outstanding Notes. ARTICLE 7. TRUSTEE Section 7.01 Duties of Trustee.

LEGAL DEFEASANCE AND COVENANT DEFEASANCE Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance. The Company may, at the option of its Board of Directors evidenced by a resolution set forth in an Officer's Certificate, at any time, elect to have either Section 8.02 or 8.03 hereof be applied to all outstanding Notes upon compliance with the conditions set forth below in this Article 8. Section 8.02 Legal Defeasance and Discharge. Upon the Company's exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Company will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes on the date the conditions set forth below are satisfied (hereinafter, "Legal Defeasance"). For this purpose, Legal Defeasance means that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes, which shall thereafter be deemed to be "outstanding" only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in clauses (1) and (2) below, and to have satisfied all their other obligations under such Notes and this Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder: (1) the rights of Holders of outstanding Notes to receive payments in respect of the principal of, or interest or premium, if any, on such Notes when such payments are due from the trust referred to in Section 8.04 hereof; (2) the Company's obligations with respect to such Notes under Article 2 and Section 4.02 hereof; (3) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Company's obligations in connection therewith; and (4) this Article 8.

For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon the Company's exercise under Section 8.01 hereof of the option applicable to this Section 8.03 hereof, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(3) through 6.01(7) hereof shall not constitute Events of Default.

In order to exercise either Legal Defeasance or Covenant Defeasance under either Section 8.02 or 8.03 hereof: (1) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash in United States dollars, non-callable Government Securities, or a combination thereof, in such amounts as shall be sufficient, in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants, to pay the principal of, premium, if any, and interest on the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be, and the Company must specify whether such Notes are being defeased to maturity or to a particular redemption date; (2) in the case of an election under Section 8.02 hereof, the Company has delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that: (A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling; or (B) since the date of this Indenture, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of the outstanding Notes shall not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and shall be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred; (3) in the case of an election under Section 8.03 hereof, the Company must deliver to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that the Holders of the outstanding Notes shall not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and shall be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 53 (4) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit); (5) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than this Indenture) to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound; (6) the Company must deliver to the Trustee an Officer's Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders of Notes over the other creditors of the Company with the intent of defeating, hindering, delaying or defrauding any other creditors of the Company or others; and (7) the Company must deliver to the Trustee an Officer's Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for or relating to the Legal Defeasance or the Covenant Defeasance have been complied with. Section 8.05 Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions. Subject to Section 8.06 hereof, all money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the "Trustee") pursuant to Section 8.04 hereof in respect of the outstanding Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest, but such money need not be segregated from other funds except to the extent required by law. The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable Government Securities deposited pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes. Notwithstanding anything in this Article 8 to the contrary, the Trustee shall deliver or pay to the Company from time to time upon the request of the Company any money or non-callable Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(1) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance. Section 8.06 Repayment to the Company. Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium, if any, or interest on any Note and remaining unclaimed for two years after such principal, premium, if any, or interest has become due and payable shall be paid to the Company on its request or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter be permitted to look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, 54 and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in the New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining shall be repaid to the Company. Section 8.07 Reinstatement. If the Trustee or Paying Agent is unable to apply any United States dollars or non-callable Government Securities in accordance with Section 8.02 or 8.03 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company's obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as the case may be; provided, however, that, if the Company makes any payment of principal of, premium, if any, or interest on any Note following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent. ARTICLE 9. AMENDMENT, SUPPLEMENT AND WAIVER Section 9.01 Without Consent of Holders of Notes. Notwithstanding Section 9.02 of this Indenture, the Company and the Trustee may amend or supplement this Indenture or the Notes without the consent of any Holder of a Note: (1) to cure any ambiguity, omission, defect or inconsistency; (2) to provide for the assumption of the Company's Obligations under this Indenture by a successor upon any merger, consolidation or asset transfer permitted under this Indenture; (3) to provide for uncertificated Notes in addition to or in place of certificated Notes or to provide for bearer Notes; (4) to comply with any requirement to effect or maintain the qualification of the indenture under the TIA; (5) to provide for the issuance of Additional Notes in accordance with the limitations set forth in Section 4.21; (6) to conform the text of the Indenture or the Notes to any provisions of the Description of the Notes section of the Offering Circular to the extent that such provision of the Description of the Notes section of the Offering Circular was intended to be a verbatim recitation of a provision of the Indenture or the Notes; (7) to add covenants that would benefit the Holders of Notes or to surrender any rights the Company has under this Indenture; or 55 (8) to make any change that does not adversely affect the rights of any Holder of the Notes, including, without limitation, changing any payment record dates as necessary to conform to the then current market practice. Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental Indenture, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee shall join with the Company in the execution of any amended or supplemental Indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to enter into such amended or supplemental Indenture that affects its own rights, duties or immunities under this Indenture or otherwise. Section 9.02 With Consent of Holders of Notes. Except as provided below in this Section 9.02, the Company and the Trustee may amend or supplement this Indenture and the Notes with the consent of the Holders of at least a majority in principal amount of the Notes (including, without limitation, Additional Notes, if any) then outstanding voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium, if any, or interest on the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture or the Notes may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes voting as a single class (including consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes). Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental Indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee shall join with the Company in the execution of such amended or supplemental Indenture unless such amended or supplemental Indenture directly affects the Trustee's own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental Indenture. It shall not be necessary for the consent of the Holders of Notes under this Section 9.02 to approve the particular form of any proposed amendment or waiver, but it is sufficient if such consent approves the substance thereof. After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company shall mail to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amended or supplemental Indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in aggregate principal amount of the Notes then outstanding voting as a single class may waive compliance in a particular instance by the Company with any provision of this Indenture or the Notes. However, without the consent of each Holder affected, an amendment or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder): (1) reduce the amount of Notes whose Holders must consent to an amendment, supplement or waiver; 56 (2) reduce the rate of interest or change the time for payment of interest on the Notes; (3) reduce the issue price or change the stated maturity of the Notes; (4) make any change in any repurchase right to the detriment of such Holder; (5) make any change in any conversion right to the detriment of such Holder; (6) make payments on the Notes payable in currency or consideration other than as originally stated in the Notes; (7) make any change in Section 6.07 hereof; (8) make any change in Section 6.04 hereof or in the foregoing amendment and waiver provisions; or (9) waive a continuing default or Event of Default regarding any payment on the Notes. Section 9.03 Compliance with Trust Indenture Act. Every amendment or supplement to this Indenture or the Notes shall be set forth in a amended or supplemental Indenture that complies with the TIA as then in effect. Section 9.04 Revocation and Effect of Consents. Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder's Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder. Section 9.05 Notation on or Exchange of Notes. The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Company in exchange for all Notes may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver. Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver. Section 9.06 Trustee to Sign Amendments, etc. The Trustee shall sign any amended or supplemental Indenture authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Company may not sign an amendment or supplemental Indenture until the Board of Directors approves it. In executing any amended or supplemental indenture, the Trustee shall be entitled 57 to receive and (subject to Section 7.01 and 7.02 hereof) shall be fully protected in relying upon, in addition to the documents required by Section 13.04 hereof, an Officer's Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental Indenture is authorized or permitted by this Indenture. ARTICLE 10. CONVERSION Section 10.01 Conversion Privilege. (a) Subject to the provisions of this Article 10, a Holder of a Note may convert such Note into cash and Common Stock equal to the Conversion Value (as defined below) in accordance with Section 10.14, if any of the following conditions are satisfied: (1) during any calendar quarter (the "Quarter") commencing after the date of issuance of the Notes, if the Common Stock Price for at least 20 Trading Days in the period of 30 consecutive Trading Days ending on the last Trading Day of the Quarter immediately preceding the Quarter in which the conversion occurs (appropriately adjusted to take into account the occurrence, during such 30 consecutive Trading Day period, of any event requiring adjustment of the Conversion Price under this Indenture) is more than 120% of the Conversion Price on such 30th Trading Day; (2) the Note has been called for redemption by the Company pursuant to Section 3.07 and the redemption has not yet occurred, so long as the Holder surrenders such Note prior to the close of business on the date that is two Business Days prior to the applicable redemption date, even if the Note is not otherwise exchangeable at such time; (3) (A) the conversion of such Note occurs during the five Trading Day period immediately after a period of five consecutive Trading Days in which the Trading Price for each such Trading Day in such period was less than 95% of the product of (x) the Common Stock Price on such Trading Day multiplied by (y) the Conversion Rate on such Trading Day. (B) Notwithstanding the foregoing, if on the date of any conversion pursuant to Section 10.01(a)(3)(A), the Common Stock Price on such date is greater than the Conversion Price on such date but less than 120% of the Conversion Price on such date, then the Conversion Value a Holder of Notes will be entitled to receive will be equal to the principal amount of the Notes held by such Holder plus accrued and unpaid interest (and Liquidated Damages, if any) as of the Conversion Date (such a conversion, a "Principal Value Conversion") and the number of Net Shares (and any cash in lieu of fractional shares) to be delivered upon a Principal Value Conversion will be determined in accordance with Section 10.14; and provided further that, in place of the Five Day Average Closing Stock Price, such number of Net Shares will be calculated using an amount equal to the greater of (i) the Conversion Price on the Conversion Date and (ii) the Common Stock Price on the Conversion Date; (4) (i) a distribution to all or substantially all holders of Common Stock of rights, warrants or options to subscribe for or purchase, for a period expiring less than 60 days after such distribution, shares of Common Stock at a price less than the Common Stock Price on the Trading Day immediately preceding the date of declaration of such distribution or (ii) a distribution to all or substantially all holders of Common Stock evidences of Company indebtedness, rights or warrants to purchase or subscribe for Capital Stock or other securities of the Company, cash or assets, which distribution has a per share value that exceeds 12.5% of the Common Stock Price 58 on the Trading Day immediately preceding the declaration date of such distribution provided that, the Holder shall have no right to convert any Note pursuant to Section 10.01(c) hereof if the Holder of a Note otherwise participates in the issuance or distribution described in this Section 10.01(a)(4) without conversion of such Holder's Notes; or (5) (i) the Company is party to a consolidation, merger, share exchange, sale of all or substantially all of its assets or other similar transaction pursuant to which the Common Stock is subject to conversion into shares of stock (other than Common Stock), other securities or property (including cash) subject to Section 10.11 and (ii) the conversion of such Note occurs at any time from and after the date that is 15 days prior to the date of the anticipated effective time of such transaction until and including the date that is 15 days after the actual effective date of such transaction; provided that if such conversion occurs after the effective date of such transaction, the Holder will receive on conversion the consideration determined in accordance with Section 10.11. (b) In the case of Section 10.01(a)(3), the Bid Solicitation Agent shall have no obligation to determine the Trading Price of the Notes unless the Company has requested such determination in writing, and the Company shall have no obligation to make such request unless a Holder of the Notes provides the Company with reasonable evidence that the Trading Price of the Notes on any date would be less than 95% of the product of (x) the Common Stock Price on such date and (y) the Conversion Rate then in effect. Upon receipt of such reasonable evidence, the Company shall instruct the Bid Solicitation Agent in writing to determine the Trading Price beginning on the next Trading Day and on each successive Trading Day until the Trading Price of the Notes is greater than or equal to 95% of the product of the Common Stock Price and the Conversion Rate. Neither the Trustee nor the Conversion Agent shall be under any duty or obligation to make the calculations described in Section 10.01(a)(3) hereof or to determine whether the Notes are convertible pursuant to such section. The Company shall make the calculations described in Section 10.01(a)(3) hereof, using the Trading Price of the Notes provided by the Bid Solicitation Agent and will advise the Trustee (or Conversion Agent, as the case may be) within a commercially reasonable time prior to the Conversion Date (and, in any event, no later than three Business Days prior to the Conversion Date) of any determination of the Trading Price of the Notes. (c) In the case of the foregoing Sections 10.01(a)(4)(i) and 10.01(a)(4)(ii), the Company shall cause a notice of such distribution to be filed with the Trustee and the Conversion Agent and to be mailed to each Holder of Notes no later than 20 days prior to the Ex-Dividend Date for such distribution. Once the Company has given such notice, Holders may surrender their Notes for conversion at any time thereafter until the earlier of the close of business on the Business Day prior to the Ex-Dividend Date or the Company's announcement that such distribution will not take place; provided that, the Holder shall have no right to convert any Note pursuant to this Section 10.01(c) if the Holder of a Note otherwise participates in the distribution described in either Section 10.01(a)(4)(i) or 10.01(a)(4)(ii) without conversion of such Holder's Notes. The "Ex-Dividend Date" for any such distribution means the date immediately prior to the commencement of "ex-dividend" trading for such distribution on The New York Stock Exchange or such other national securities exchange or The Nasdaq Stock Market or similar system of automated dissemination of quotations of securities prices on which the Common Stock is then listed or quoted. (d) A Holder may convert a portion of a Note equal to $1,000 or any integral multiple thereof. Provisions of this Indenture that apply to conversion of all of a Note also apply to conversion of a portion of a Note. If a Note is called for redemption pursuant to Article 3, in order to convert such Note, the Holder must deliver the Note to the Conversion Agent (or, if the Note is held in book-entry form, complete and deliver to the Depositary appropriate instructions in accordance with the Applicable Procedures) at any time prior to the close of business on the day that is two Business Days prior to the 59 applicable redemption date for such Note (unless the Company shall default in paying the Purchase Price when due, in which case the conversion right shall terminate on the date such Default is cured and such Note is redeemed). A Note in respect of which a Holder has delivered a Purchase Notice pursuant to Section 3.09 exercising the option of such Holder to require the Company to repurchase such Note may be converted only if such Purchase Notice is withdrawn by a written notice of withdrawal delivered to the Paying Agent prior to the close of business on the Purchase Date in accordance with Section 3.11. A Note in respect of which a Holder has delivered a Change in Control Purchase Notice pursuant to Section 3.10 may not be converted unless such Change in Control Purchase Notice is deemed withdrawn pursuant to Section 3.11. (e) A Holder of Notes is not entitled to any rights of a holder of Common Stock until, and to the extent that, such Holder has converted its Notes into Common Stock. Section 10.02 Conversion Procedure. (a) To convert a Note, a Holder must satisfy the requirements of this Article 10 and (i) complete and manually sign the irrevocable conversion notice on the back of the Note and deliver such notice to the Conversion Agent, (ii) surrender the Note to the Conversion Agent, (iii) furnish appropriate endorsements and transfer documents if required by the Registrar or the Conversion Agent, (iv) pay any transfer or other tax, if required by Section 10.03 and/or (v) if the Note is held in book-entry form, complete and deliver to the Depositary appropriate instructions pursuant to the Applicable Procedures. The later of (x) the date on which the Holder satisfies all of the foregoing requirements and (y) the Determination Date is the "Conversion Date." As soon as practicable after the Conversion Date and in any event within four Business Days thereof, the Company shall deliver to the Holder through the Conversion Agent (1) cash in the amount calculated in accordance with Section 10.14 and (2) either (A) a certificate for or (B) a book-entry notation of the number of whole shares of Common Stock issuable upon the conversion and cash in lieu of any fractional shares pursuant to Section 10.14. (b) The Person in whose name the Note is registered shall be deemed to be a stockholder of record on the Conversion Date; provided that no surrender of a Note on any date when the stock transfer books of the Company shall be closed shall be effective to constitute the Person or Persons entitled to receive the shares of Common Stock upon such conversion as the record holder or holders of such shares of Common Stock on such date, but such surrender shall be effective to constitute the Person or Persons entitled to receive such shares of Common Stock as the record holder or holders thereof for all purposes at the close of business on the next succeeding day on which such stock transfer books are open (subject to the provisions of the next paragraph of this Section 10.02); provided that such conversion shall be at the Conversion Price in effect on the date that such Note shall have been surrendered for conversion, as if the stock transfer books of the Company had not been closed. Upon conversion of a Note, such Person shall no longer be a Holder of such Note. (c) No payment or adjustment will be made for accrued interest (including Liquidated Damages, if any), on a converted Note or for dividends or distributions on shares of Common Stock issued upon conversion of a Note (provided that the shares of Common Stock received upon conversion of Notes shall continue to accrue Liquidated Damages, as applicable, in accordance with the Registration Rights Agreement and shall be entitled to receive, at the next interest payment date, any accrued but unpaid Liquidated Damages with respect to the converted Notes), but if any Holder surrenders a Note for conversion between the record date for the payment of an installment of interest and the next interest payment date, then, notwithstanding such conversion, the interest (including Liquidated Damages, if any), payable on such interest payment date shall be paid to the Holder of such Note on such interest payment date. In such event, such Note, when surrendered for conversion, must be accompanied by delivery of a check payable to the Conversion Agent in an amount equal to the interest (including Liquidated Damages, 60 if any), payable on such interest payment date on the portion so converted. If such payment does not accompany such Note, the Note shall not be converted; provided that no such check shall be required if such Note has been called for redemption on a redemption date within the period between and including such record date and such interest payment date, or if such Note is surrendered for conversion on the interest payment date. If the Company defaults in the payment of interest (including Liquidated Damages, if any), payable on the interest payment date, the Conversion Agent shall repay such funds to the Holder. (d) Upon surrender of a Note that is converted in part, the Company shall execute, and the Trustee shall, upon receipt of an Authentication Order, authenticate and deliver to the Holder, a new Note equal in principal amount to the unconverted portion of the Note surrendered. Section 10.03 Taxes on Conversion. If a Holder submits a Note for conversion, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue of shares of Common Stock upon the conversion. However, the Holder shall pay any such tax which is due because the Holder requests the shares to be issued in a name other than the Holder's name. The Conversion Agent may refuse to deliver the certificates representing the shares of Common Stock being issued in a name other than the Holder's name until the Conversion Agent receives a sum sufficient to pay any tax which will be due because the shares are to be issued in a name other than the Holder's name. Nothing herein shall preclude any income tax withholding required by law or regulations. Section 10.04 Company to Provide Stock. The Company has reserved shares of Common Stock to permit delivery of shares of Common Stock upon conversion of the Notes up to an assumed Five Day Average Closing Stock Price, and from time to time as may be necessary shall reserve out of its authorized but unissued shares of Common Stock a sufficient number of additional shares of Common Stock to permit delivery of shares of Common Stock upon the conversion of the Notes in full. All shares of Common Stock delivered upon conversion of the Notes shall be newly issued shares or treasury shares, shall be duly and validly issued and fully paid and nonassessable, and shall be free from preemptive rights and free of any lien or adverse claim. The Company will endeavor promptly to comply with all federal and state securities laws regulating the offer and delivery of shares of Common Stock upon conversion of Notes, if any, and will list or cause to have quoted such shares of Common Stock on each national securities exchange or in the over-the-counter market or such other market on which the shares of Common Stock are then listed or quoted. Section 10.05 Adjustment of Conversion Price. The conversion price (the "Conversion Price") initially shall be that price set forth in paragraph 9 of the Notes, but shall be adjusted (without duplication) from time to time by the Company as follows: (a) In case the Company shall pay a dividend or make a distribution on the Common Stock payable exclusively in Common Stock, the Conversion Rate in effect at the opening of business on the day following the date fixed for the determination of stockholders entitled to receive such dividend or other distribution shall be increased by multiplying such Conversion Rate by a fraction of which the denominator shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination and the numerator shall be the sum of (i) such number of shares and (ii) 61 or distribution is not so paid or made, the Conversion Price shall be adjusted the total number of shares constituting such dividend or other distribution, such increase to become effective immediately after the opening of business on the day following the date fixed for such determination. For the purposes of this paragraph (a), the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company. In the event that such dividend or distribution is not so paid or made, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such dividend or distribution had not occurred. (b) In case the Company shall pay or make a dividend or other distribution on its Common Stock consisting exclusively of, or shall otherwise issue to all holders of its Common Stock, rights, warrants or options, in each case entitling the holders thereof to subscribe for or purchase shares of Common Stock at a price per share less than the Market Price per share of the Common Stock on the date fixed for the determination of stockholders entitled to receive such rights, warrants or options, the Conversion Rate in effect at the opening of business on the day following the date fixed for such determination shall be increased by multiplying such Conversion Rate by a fraction of which the denominator shall be the sum of (i) the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination plus (ii) the number of shares of Common Stock which the aggregate of the offering price of the total number of shares of Common Stock so offered for subscription or purchase would purchase at such Market Price and the numerator shall be the sum of (i) the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination plus (ii) the number of shares of Common Stock so offered for subscription or purchase, such increase to become effective immediately after the opening of business on the day following the date fixed for such determination; provided, however, that no adjustment shall be made if Holders of the Notes may participate in the transaction on a basis and with notice that the Company's Board of Directors deems to be fair and appropriate. To the extent that rights are not so issued or shares of Common Stock are not so delivered after the expiration of such rights, warrants or options, the Conversion Rate shall be readjusted to the Conversion Rate which would then be in effect if such date fixed for the determination of stockholders entitled to receive such rights, warrants or options, had not been fixed. For the purposes of this paragraph (b), the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company. (c) In case the Company shall declare a cash dividend or distribution to all or substantially all of the holders of Common Stock, the Conversion Price shall be decreased so that the Conversion Price shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the record date for such dividend or distribution by a fraction, (i) the numerator of which shall be the average of the Common Stock Prices for the three consecutive Trading Days ending on the date immediately preceding the record date for such dividend or distribution (the "Pre-Dividend Sale Price"), minus the full amount of such cash dividend or distribution, to the extent payable in cash, applicable to one share of Common Stock, and (ii) the denominator of which shall be the Pre-Dividend Sale Price, such adjustment to become effective immediately after the record date for such dividend or distribution; provided, that no adjustment to the Conversion Price or the ability of a Holder of a Note to convert will be made pursuant to this Section 10.05(c) if the Company provides that Holders of Notes will participate in such cash dividend or distribution on an as-converted basis without conversion; provided further, that if the numerator of the foregoing fraction is less than $1.00 (including a negative amount), then in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder shall have the right to receive upon conversion, in addition to the Common Stock issuable upon such conversion (and any cash in lieu of fractional shares), the amount of cash such Holder would have received had such Holder converted its Note immediately prior to the record date for such dividend or distribution. If such dividend 62 to the Conversion Price that would then be in effect if such dividend or distribution had not been declared. (d) Subject to the last sentence of this paragraph (d), in case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock evidences of its indebtedness, shares of any class or series of Capital Stock, cash or assets (including securities, but excluding any rights, warrants or options referred to in paragraph (b) of this Section 10.05, any dividend or distribution paid exclusively in cash and any dividend or distribution referred to in paragraph (a) of this Section 10.05), the Conversion Rate shall be increased so that the same shall equal the price determined by multiplying the Conversion Rate in effect immediately prior to the effectiveness of the Conversion Rate increase contemplated by this paragraph (d) by a fraction of which the denominator shall be the Market Price per share of the Common Stock on the date fixed for the determination of stockholders entitled to receive such distribution (the "Reference Date") less the Fair Market Value, on the Reference Date, of the portion of the evidences of indebtedness, shares of capital stock, cash and/or assets so distributed applicable to one share of Common Stock and the numerator shall be such Market Price per share of the Common Stock, such increase to become effective immediately prior to the opening of business on the day following the Reference Date, provided that if the Fair Market Value of the portion of the evidences of indebtedness, shares of capital stock, cash and/or assets so distributed applicable to one share of Common Stock shall be less than the Market Price per share of Common Stock, no adjustment shall be made; and provided, further, that no adjustment shall be made if all Holders of Notes are entitled to participate in such transactions. 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 occurred. For purposes of this paragraph (d), any dividend or distribution that includes shares of Common Stock or rights, warrants or options to subscribe for or purchase shares of Common Stock shall be deemed instead to be (i) a dividend or distribution of the evidences of indebtedness, shares of Capital Stock, cash and/or assets other than such shares of Common Stock or such rights or warrants (making any Conversion Rate increase required by this paragraph (d)) immediately followed by (ii) a dividend or distribution of such shares of Common Stock or such rights, warrants or options (making any further Conversion Rate increase required by paragraph (a) or (b) of this Section 10.05), except any shares of Common Stock included in such dividend or distribution shall not be deemed "outstanding at the close of business on the date fixed for such determination" within the meaning of paragraph (a) of this Section 10.05. (e) In case outstanding shares of Common Stock shall be subdivided into a greater number of shares of Common Stock, the Conversion Rate in effect at the opening of business on the Business Day following the day upon which such subdivision becomes effective shall be proportionately increased and, conversely, in case outstanding shares of Common Stock shall each be combined into a smaller number of shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the day upon which such combination becomes effective shall be proportionately reduced, such increase or reduction, as the case may be, to become effective immediately after the opening of business on the Business Day following the day upon which such subdivision or combination becomes effective. (f) In case the Company pays to holders of Common Stock in respect of a tender or exchange offer, other than an odd-lot offer, by the Company or any of its Subsidiaries for Common Stock to the extent that the offer involves aggregate consideration that, together with (1) any cash and the Fair Market Value of any other consideration payable in respect of any tender offer by the Company or any of its Subsidiaries for shares of Common Stock consummated within the preceding 12 months not triggering a Conversion Rate adjustment and (2) all-cash distributions to all or substantially all holders of the Company's Common Stock made within the preceding 12 months not triggering a Conversion Rate adjustment, exceeds an amount equal to 12.5% of the market capitalization of Common Stock on the expiration date of the tender offer, the Conversion Rate shall be increased so that the same shall equal the 63 price determined by multiplying the Conversion Rate in effect immediately prior to the effectiveness of the Conversion Rate increase contemplated by this Section 10.05(f) by a fraction of which the denominator shall be the number of shares of Common Stock outstanding (including any tendered or exchanged shares) at the last time tenders of exchanges may be made pursuant to such tender or exchange offer (the "Expiration Time") multiplied by the Market Price per share of the Common Stock on the Trading Day next succeeding the Expiration Time and the numerator shall be the sum of (x) the Fair Market Value (determined as aforesaid) of the aggregate consideration payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender or exchange offer) of all shares validly tendered or exchanged and not withdrawn as of the Expiration Time (the shares deemed so accepted, up to any such maximum, being referred to as the "Purchased Shares") and (y) the product of the number of shares of Common Stock outstanding (less any Purchased Shares) at the Expiration Time and the Market Price per share of the Common Stock on the Trading Day next succeeding the Expiration Time, such increase to become effective immediately prior to the opening of business on the Business Day following the Expiration Time. In any case in which this Section 10.05 shall require that an adjustment be made immediately following a record date established for purposes of this Section 10.05, the Company may elect to defer (but only until five Business Days following the filing by the Company with the Trustee of the certificate described in Section 10.09) issuing to the holder of any Note converted after such record date the shares of Common Stock issuable upon such conversion over and above the shares of Common Stock issuable upon such conversion only on the basis of the Conversion Price prior to adjustment; and, in lieu of the shares the issuance of which is so deferred, the Company shall issue or cause its transfer agents to issue due bills or other appropriate evidence of the right to receive such shares. Section 10.06 When No Adjustment Required. No adjustment of the Conversion Price shall be made: (a) upon the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on securities of the Company and the investment of additional optional amounts in shares of Common Stock under any plan, (b) upon the issuance of any shares of Common Stock or options or rights to purchase those shares pursuant to any present or future employee, director or consultant benefit plan or program of the Company, (c) upon the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security outstanding as of the date hereof, (d) upon the issuance of any rights, any distribution of separate certificates representing the rights, any exercise or redemption of any rights or any termination or invalidation of the rights, pursuant to the Company's stockholders rights plan, or (e) for a change in the par value or no par value of the shares of Common Stock. There shall also be no adjustment of the Conversion Rate in case of the issuance of any Common Stock (or securities convertible into or exchangeable for Common Stock), except as specifically described above. 64 Section 10.07 When Adjustment May Be Deferred. No adjustment in the Conversion Price need be made unless the adjustment would require an increase or decrease of at least 1% in the Conversion Price (other than an adjustment described in Section 10.05(f)). Any adjustments that are not made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Article 10 shall be made to the nearest cent, with one-half cent rounded up, or to the nearest 1/1,000th of a share, with 1/500th of a share being rounded up, as the case may be. Section 10.08 Successive Adjustments. After an adjustment to the Conversion Price under this Article 10, any subsequent event requiring an adjustment under this Article 10 shall cause an adjustment to the Conversion Rate as so adjusted. Section 10.09 Notice of Adjustment. Whenever the Conversion Price is adjusted, the Company shall promptly mail to Holders of Notes a notice of the adjustment and concurrently file with the Trustee and the Conversion Agent such notice and a certificate from the Company's independent public accountants briefly stating the facts requiring the adjustment and the manner of computing such adjustment. The certificate shall be conclusive evidence that such adjustment is correct. Neither the Trustee nor any Conversion Agent shall be under any duty or responsibility with respect to any such notice and certificate (or the receipt of such notice and certificate or with the knowledge of any adjustment absent such notice and certificate) except to exhibit the same to any Holder desiring inspection thereof. Section 10.10 Notice of Certain Transactions. The Company shall mail to Holders of Notes and file with the Trustee and/or the Conversion Agent a notice stating the proposed record date for a dividend or distribution or the proposed effective date of a subdivision, combination, reclassification, consolidation, merger, binding share exchange, transfer, liquidation or dissolution, if any of the following occur: (a) the Company takes any action that would require an adjustment in the Conversion Rate pursuant to Section 10.05 (unless no adjustment is to occur pursuant to Section 10.06); or (b) the Company takes any action that would require a supplemental indenture pursuant to Section 10.11; or (c) there is a liquidation or dissolution of the Company. The Company shall file and mail such notice at least 15 days before the applicable date of any such transaction. Failure to file or mail the notice or any defect in it shall not affect the validity of the transaction. Section 10.11 Effect of Reclassification, Consolidation, Merger, Share Exchange or Sale on Conversion Privilege. If any of the following shall occur: (i) any reclassification or change of outstanding shares of Common Stock (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination); (ii) any consolidation, combination, merger or share exchange to which the Company is a party other than a merger in which the Company is the 65 continuing corporation and which does not result in any reclassification of, or change (other than a change in name, or par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination) in, outstanding shares of Common Stock; or (iii) any sale or conveyance of all or substantially all of the assets of the Company; then the Company, or such successor or purchasing corporation, as the case may be, shall, as a condition precedent to such reclassification, change, consolidation, merger, share exchange, sale or conveyance, execute and deliver to the Trustee a supplemental indenture providing that the Holder of each Note then outstanding shall have the right to convert such Note into the kind and amount of shares of Capital Stock and other securities and property (including cash) receivable upon such reclassification, change, consolidation, merger, share exchange, sale or conveyance by a holder of the number of shares of Common Stock deliverable upon conversion of such Note immediately prior to such reclassification, change, consolidation, merger, share exchange, sale or conveyance. Such supplemental indenture shall provide for adjustments of the Conversion Price which shall be as nearly equivalent as may be practicable to the adjustments of the Conversion Price provided for in this Article 10. If, in the case of any such consolidation, merger, share exchange, sale or conveyance, the stock or other securities and property (including cash) receivable thereupon by a holder of Common Stock includes shares of Capital Stock or other securities and property of a corporation other than the successor or purchasing corporation, as the case may be, in such consolidation, merger, share exchange, sale or conveyance, then such supplemental indenture shall also be executed by such other corporation and shall contain such additional provisions to protect the interests of the Holders of the Notes as the Board of Directors of the Company shall reasonably consider necessary by reason of the foregoing. The provision of this Section 10.11 shall similarly apply to successive consolidations, mergers, share exchanges, sales or conveyances. Notwithstanding the foregoing, a distribution by the Company to all or substantially all holders of its Common Stock for which an adjustment to the Conversion Price or provision for conversion of the Notes may be made pursuant to Section 10.05 shall not be deemed to be a sale or conveyance of all or substantially all of the assets of the Company for purposes of this Section 10.11. In the event the Company shall execute a supplemental indenture pursuant to this Section 10.11, the Company shall promptly file with the Trustee an Opinion of Counsel stating that such supplemental indenture is authorized or permitted by this Indenture and an Officer's Certificate briefly stating (a) the reasons therefor, (b) the kind or amount of shares of stock or securities or property (including cash) receivable by Holders of the Notes upon the conversion of their Notes after any such reclassification, change, consolidation, merger, share exchange, sale or conveyance, (c) any adjustment to be made with respect thereto and (d) that all conditions precedent have been complied with. Section 10.12 Trustee's Disclaimer. The Trustee has no duty to determine when an adjustment under this Article 10 should be made, how it should be made or what such adjustment should be made, but may accept as conclusive evidence of the correctness thereof, and shall be protected in relying upon, the Officer's Certificate with respect thereto, which the Company is obligated to file with the Trustee pursuant to Section 10.09. The Trustee shall not be accountable for and makes no representation as to the validity or value of any securities or assets issued upon conversion of Notes, and the Trustee shall not be responsible for the Company's failure to comply with any provisions of this Article 10. Each Conversion Agent (other than the Company or an Affiliate of the Company) shall have the same protection under this Section 10.12 as the Trustee. The Trustee shall not be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture executed pursuant to Section 10.11, but may accept as conclusive evidence of the correctness thereof, and shall be protected in relying upon, the Officer's Certificate with respect thereto, which the Company is obligated to file with the Trustee pursuant to Section 10.11 of this Indenture. 66 Section 10.13 Voluntary Reduction. The Company from time to time may decrease the Conversion Price by any amount at any time for at least 20 days, so long as the decrease is irrevocable during such 20-day period. Whenever the Conversion Price is decreased, the Company shall mail to Holders of Notes and file with the Trustee and the Conversion Agent a notice of the decrease. The Company shall mail the notice at least 15 days before the date the decreased Conversion Price takes effect. The notice shall state the decreased Conversion Price and the period during which it will be in effect. A voluntary decrease of the Conversion Price does not change or adjust the Conversion Price otherwise in effect for purposes of Section 10.14 Section 10.14 Conversion Value of Notes Tendered. (a) Subject to certain exceptions described in Sections 10.01(a)(3) and 10.01(a)(4), Holders tendering the Notes for conversion shall be entitled to receive, upon conversion of such Notes, cash and shares of Common Stock, the value of which (the "Conversion Value") shall be equal to the product of: (1) (A) the aggregate principal amount of Notes to be converted divided by 1,000 multiplied by (B) the Conversion Rate; and (2) the average of the Common Stock Price for the five consecutive Trading Days (appropriately adjusted to take into account the occurrence during such period of stock splits and similar events) including and immediately following the second Trading Day following the day the Notes are tendered for conversion (the "Five Day Average Closing Stock Price"); provided that, if the shares of Common Stock are not listed on The New York Stock Exchange, then the Five Day Average Closing Stock Price shall be determined by the Company by reference to the Common Stock Price as reported by NASDAQ. (b) Subject to certain exceptions described below and under Sections 10.01(a)(3) and 10.01(a)(4), the Company shall deliver the Conversion Value to converting holders as follows: (1) an amount in cash (the "Principal Return") equal to the lesser of (a) the aggregate Conversion Value of the Notes to be converted and (b) the aggregate principal amount of the Notes to be converted; (2) if the aggregate Conversion Value of the Notes to be converted is greater than the aggregate Principal Return of the Notes to be converted, an amount in shares (the "Net Shares"), determined as set forth below, equal to the difference between such aggregate Conversion Value and such aggregate Principal Return (the "Net Share Amount"); and (3) an amount paid in cash, determined as set forth below, for any fractional shares of Common Stock. The number of Net Shares to be paid shall be determined by dividing the Net Share Amount by the Five Day Average Closing Stock Price. Holders of Notes will not receive a fractional share upon conversion of a Note. Instead, the Holder will receive cash for the value of the fractional share. The cash payment for fractional shares shall be based on the Five Day Average Closing Stock Price. The Conversion Value, Principal Return, number of Net Shares and Net Share Amount shall be determined by the Company at the end of the fifth consecutive Trading Day including and immediately 67 following the second Trading Day after the day the Notes are tendered for conversion (the "Determination Date"). (c) The Company shall pay the Principal Return and cash for fractional shares and deliver the Net Shares, if any, as promptly as practicable after the Conversion Date, but in no event later than four Business Days thereafter. Delivery of the Principal Return, Net Shares and cash in lieu of fractional shares shall be deemed to satisfy the Company's obligation to pay the principal amount of the Notes, including accrued interest and Liquidated Damages, if any, payable on the Notes, except as described below. Accrued interest shall be deemed paid in full rather than canceled, extinguished or forfeited. The Company shall not adjust the Conversion Price to account for the accrued interest. Nonetheless, if Notes are converted after a regular record date and prior to the opening of business on the next interest payment date, including the date of maturity, Holders of such Notes, at the close of business on the next regular record date shall receive the interest (and Liquidated Damages, if any) payable on such Notes on the corresponding interest payment date notwithstanding the conversion. (d) If an Event of Default, as described under Section 6.01 of this Indenture has occurred and is continuing (other than a Default in a cash payment upon conversion of the Notes), the Company may not pay cash upon conversion of any Notes (other than cash in lieu of fractional shares) and instead will make payment only through the delivery of shares of Common Stock. The number of shares of Common Stock to be delivered will be equal to (A) the aggregate principal amount of Notes to be converted divided by 1,000 multiplied by (B) the Conversion Rate. (e) Neither the Trustee nor the Conversion Agent has any duty to determine or calculate the Conversion Value, Principal Return, number of Net Shares, the Net Share Amount of any other computation required under this Article 10, all of which shall be determined by the Company (or the Bid Solicitation Agent, as the case may be) in accordance with the provisions of this Indenture and the Trustee and Conversion Agent shall not be under any responsibility to determine the correctness of any such determinations and/or calculations and may conclusively rely on the correctness thereof. ARTICLE 11. SATISFACTION AND DISCHARGE Section 11.01 Satisfaction and Discharge. This Indenture shall be discharged and shall cease to be of further effect as to all Notes issued hereunder, when: (1) either: (a) all Notes that have been authenticated under the Original Indenture and this Indenture (except lost, stolen or destroyed Notes that have been replaced or paid and Notes for whose payment money has theretofore been deposited in trust and thereafter repaid to the Company) have been delivered to the Trustee for cancellation; or (b) all Notes that have not been delivered to the Trustee for cancellation have become due and payable by reason of the making of a notice of redemption or otherwise or shall become due and payable within one year and the Company has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as shall be sufficient without consideration of any reinvestment of interest, to pay and 68 discharge the entire indebtedness on the Notes not delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest to the date of maturity or redemption; (2) no Default or Event of Default has occurred and is continuing on the date of such deposit or shall occur as a result of such deposit and such deposit shall not result in a breach or violation of, or constitute a default under, any other instrument to which the Company is a party or by which the Company is bound; (3) the Company has paid or caused to be paid all sums payable by it under this Indenture; and (4) the Company has delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money toward the payment of the Notes at maturity or the redemption date, as the case may be. In addition, the Company must deliver an Officer's Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied. Notwithstanding the satisfaction and discharge of this Indenture, if money has been deposited with the Trustee pursuant to subclause (b) of clause (1) of this Section, the provisions of Section 11.02 and Section 8.06 shall survive. In addition, nothing in this Section 11.01 shall be deemed to discharge those provisions of Section 7.07 hereof, that, by their terms, survive the satisfaction and discharge of this Indenture. Section 11.02 Application of Trust Money. Subject to the provisions of Section 8.06, all money deposited with the Trustee pursuant to Section 11.01 shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law. If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with Section 11.01 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company's obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 11.01; provided that if the Company has made any payment of principal of, premium, if any, or interest on any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent. ARTICLE 12. MISCELLANEOUS Section 12.01 Trust Indenture Act Controls. If any provision of this Indenture limits, qualifies or conflicts with the duties imposed by TIA Section 318(c), the imposed duties or provisions of the TIA shall control. 69 Section 12.02 Notices.

The waiver may not be effective to waive liabilities under the federal securities laws. Section 12.08 Governing Law.

The Company shall pay interest semi-annually in arrears on May 15 and November 15 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an "Interest Payment Date").

The repurchase price payable will be equal to 100% of the principal amount of the Notes plus any accrued and unpaid interest (and Liquidated Damages, if any) to such repurchase date.
