The following TIA terms used in this Indenture have the following meanings: "indenture securities" means the Notes and the Subsidiary Guarantees; "indenture security Holder" means a Holder of a Note; "indenture to be qualified" means this Indenture; "indenture trustee" or "institutional trustee" means the Trustee; "obligor" on the Notes means the Company, any Subsidiary Guarantor and any successor obligor upon the Notes. All other terms used in this Indenture that are defined by the TIA, defined by TIA reference to another statute or defined by SEC rule under the TIA have the meanings so assigned to them. RULES OF CONSTRUCTION. Unless the context otherwise requires: a term has the meaning assigned to it; an accounting term not otherwise defined has the meaning assigned to it in accordance with GAAP; "or" is not exclusive; words in the singular include the plural, and in the plural include the singular; provisions apply to successive events and transactions; and references to sections of or rules under the Securities Act shall be deemed to include substitute, replacement of successor sections or rules adopted by the Commission from time to time. THE NOTES FORM AND DATING. The Series A Notes, the notation thereon relating to the Subsidiary Guarantees and the Trustee's certificate of authentication shall be substantially in the form of Exhibit A hereto. The Series B Notes, the notation thereon relating to the Subsidiary Guarantees and the Trustee's certificate of authentication shall be substantially in the form of Exhibit B hereto. The Notes may have notations, legends or endorsements required by law, stock exchange rule or usage. Each Note shall be dated the date of its authentication. The Notes shall be issued in minimum denominations of $1,000 and integral multiples thereof. 16 The Series A Notes and the Series B Notes shall be considered collectively to be a single class for all purposes of this Indenture, including, without limitation, waivers, amendments, redemptions and offers to purchase. The terms and provisions contained in the form of the Notes and the notation thereon relating to the Subsidiary Guarantees annexed hereto as Exhibit A and Exhibit B and the Subsidiary Guarantees shall constitute, and are hereby expressly made, a part of this Indenture and the Company and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. Notes issued in global form shall be substantially in the form of Exhibit A or Exhibit B attached hereto, as applicable (including, in each case, the text referred to in the footnotes thereto). Notes issued in definitive form shall be substantially in the form of Exhibit A or Exhibit B attached hereto, as applicable (but without including the text referred to in the footnotes thereto). If required by the applicable procedures of the Depository, the Company may issue multiple Global Notes to represent the outstanding Notes, including separate Global Notes for Notes originally issued to (i) "qualified institutional buyers" (as defined in Rule 144 under the Securities Act), (ii) non-U.S. Persons in an offshore transaction under Regulation S of the Securities Act and (iii) institutional "accredited investors" (as defined in Rule 501(a) under the Securities Act). Each Global Note shall represent such of the outstanding Notes as shall be specified therein and each shall provide that it shall represent the aggregate amount of outstanding Notes from time to time endorsed thereon and that the aggregate amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the amount of outstanding Notes represented thereby shall be made by the Trustee or the Note Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.06 hereof. The Original Notes shall be issued only in global form. EXECUTION AND AUTHENTICATION. One Officer shall sign the Notes for the Company by manual or facsimile signature. If an Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note shall nevertheless be valid. Each Subsidiary Guarantor shall execute its Subsidiary Guarantee in the manner set forth in Section 10.07. A Note shall not be valid until authenticated by the manual signature of the Trustee. The signature shall be conclusive evidence that the Note has been authenticated under this Indenture. The Trustee shall authenticate (i) the Series A Notes for original issue on the Issue Date up to the aggregate principal amount of $250,000,000 (the "Original Notes"), (ii) Additional Series A Notes for original issue from time to time after the Issue Date in such principal amounts as may be set forth in a written order of the Company described in this sentence and (iii) the Exchange Notes from time to time for issue only in exchange for a like principal amount of Series A Notes pursuant to an Exchange Offer, in each case upon a written order of the Company signed by two Officers, which written order shall specify (a) the amount of Notes to be authenticated and the date of original issue thereof, (b) whether the Notes are Series A Notes or Series B Notes, and (c) the amount of Notes to be issued in global form or definitive form. In the event that the Company delivers a written order to authenticate Additional Series A Notes, as contemplated in clause (ii) of the preceding sentence, such order shall be accompanied by an Officers' Certificate and an Opinion of Counsel confirming that the issuance of such Additional Series A Notes complies with the requirements of Section 4.09 hereof and all other applicable requirements of this Indenture. The aggregate principal amount of Notes outstanding at any time may not exceed (i) $250,000,000, plus (ii) such additional principal amounts as may be issued and authenticated pursuant to clause (ii) of this paragraph, except as provided in Section 2.07 hereof. The Trustee may appoint an authenticating agent acceptable to the Company to authenticate Notes. An authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with the Company or an Affiliate of the Company. 17 REGISTRAR AND PAYING AGENT. The Company shall maintain an office or agency where Notes may be presented for registration of transfer or for exchange ("Registrar") and an office or agency where Notes may be presented for payment ("Paying Agent"). The Registrar shall keep a register of each series of the Notes and of their transfer and exchange. The Company may appoint one or more co-registrars and one or more additional paying agents. The term "Registrar" includes any co-registrar and the term "Paying Agent" includes any additional paying agent. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company shall notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Company or any of its Subsidiaries may act as Paying Agent or Registrar. The Company initially appoints The Depository Trust Company ("DTC") to act as Depository with respect to the Global Notes. The Company initially appoints the Trustee to act as the Registrar and Paying Agent and to act as Note Custodian with respect to the Global Notes. PAYING AGENT TO HOLD MONEY IN TRUST. The Company shall require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal, premium or Liquidated Damages, if any, or interest on the Notes, and will notify the Trustee of any default by the Company in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Company or a Subsidiary thereof) shall have no further liability for the money. If the Company or a Subsidiary thereof acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Company, the Trustee shall serve as Paying Agent for the Notes. HOLDER LISTS. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders and shall otherwise comply with TIA Section 312(a). If the Trustee is not the Registrar, the Company shall furnish to the Trustee at least seven Business Days before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders of Notes and the Company shall otherwise comply with TIA Section 312(a). TRANSFER AND EXCHANGE. Transfer and Exchange of Definitive Notes. When Definitive Notes are presented by a Holder to the Registrar with a request: (x) to register the transfer of the Definitive Notes; or (y) to exchange such Definitive Notes for an equal principal amount of Definitive Notes of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested if its requirements for such transactions are met; provided, however, that the Definitive Notes presented or surrendered for register of transfer or exchange: 18 shall be duly endorsed or accompanied by a written instruction of transfer in form satisfactory to the Registrar duly executed by such Holder or by his attorney, duly authorized in writing; and in the case of a Definitive Note that is a Transfer Restricted Security, such request shall be accompanied by the following additional information and documents, as applicable: if such Transfer Restricted Security is being delivered to the Registrar by a Holder for registration in the name of such Holder, without transfer, a certification to that effect from such Holder (in substantially the form of Exhibit C hereto); or if such Transfer Restricted Security is being transferred to a "qualified institutional buyer" (as defined in Rule 144A under the Securities Act) in accordance with Rule 144A under the Securities Act or pursuant to an exemption from registration in accordance with Rule 144 or Rule 904 under the Securities Act or pursuant to an effective registration statement under the Securities Act, a certification to that effect from such Holder (in substantially the form of Exhibit C hereto); or if such Transfer Restricted Security is being transferred in reliance on another exemption from the registration requirements of the Securities Act, a certification to that effect from such Holder (in substantially the form of Exhibit C hereto) and an Opinion of Counsel from such Holder or the transferee reasonably acceptable to the Company and to the Registrar to the effect that such transfer is in compliance with the Securities Act. Transfer of a Definitive Note for a Beneficial Interest in a Global Note. If issued, a Definitive Note may not be exchanged for a beneficial interest in a Global Note. Transfer and Exchange of Global Notes. The transfer and exchange of Global Notes or beneficial interests therein shall be effected through the Depository, in accordance with this Indenture and the procedures of the Depository therefor, which shall include restrictions on transfer comparable to those set forth in subsection (a) of this Section 2.06 to the extent required by the Securities Act. Transfer of a Beneficial Interest in a Global Note for a Definitive Note. Any Person having a beneficial interest in a Global Note may exchange such beneficial interest for a Definitive Note only under the circumstances contemplated by subsection (f) of this Section 2.06. Restrictions on Transfer and Exchange of Global Notes. Notwithstanding any other provision of this Indenture, a Global Note may not be transferred as a whole except by the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or another nominee of the Depository or by the Depository or any such nominee to a successor Depository or a nominee of such successor Depository. Authentication of Definitive Notes in Absence of Depository. If at any time: the Depository for the Notes notifies the Company that the Depository is unwilling or unable to continue as Depository for the Global Notes and a successor Depository for the Global Notes is not appointed by the Company within 90 days after delivery of such notice; or the Company, at its discretion, notifies the Trustee in writing that it elects to cause the issuance of Definitive Notes under this Indenture, 19 then the Company shall execute, and the Trustee shall authenticate and deliver, Definitive Notes in an aggregate principal amount equal to the principal amount of the Global Notes in exchange for such Global Notes. Legends. Except as permitted by the following paragraphs (ii) and (iii), each Note certificate evidencing Global Notes and Definitive Notes (and all Notes issued in exchange therefor or substitution thereof) shall bear a legend in substantially the following form, until the expiration of the applicable holding period with respect to the Notes set forth in Rule 144(k) under the Securities Act: "THE NOTE (OR ITS PREDECESSOR) EVIDENCED HEREBY WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER SECTION 5 OF THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND THE NOTE EVIDENCED HEREBY MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM. EACH PURCHASER OF THE NOTE EVIDENCED HEREBY IS HEREBY NOTIFIED THAT THE SELLER MAY BE RELYING ON THE EXEMPTION PROVIDED BY RULE 144A UNDER THE SECURITIES ACT. THE HOLDER OF THE NOTE EVIDENCED HEREBY AGREES FOR THE BENEFIT OF THE ISSUER THAT (A) SUCH NOTE MAY BE RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (1) (a) TO A PERSON WHO THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (b) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144 UNDER THE SECURITIES ACT, (c) OUTSIDE THE UNITED STATES TO A FOREIGN PERSON IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 904 UNDER THE SECURITIES ACT OR (d) IN ACCORDANCE WITH ANOTHER EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT (AND BASED UPON AN OPINION OF COUNSEL IF THE ISSUER SO REQUESTS), (2) TO THE ISSUER OR (3) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT AND, IN EACH CASE, IN ACCORDANCE WITH THE APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES OR ANY OTHER APPLICABLE JURISDICTION AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY PURCHASER OF THE NOTE EVIDENCED HEREBY OF THE RESALE RESTRICTIONS SET FORTH IN (A) ABOVE." Upon any sale or transfer of a Transfer Restricted Security (including any beneficial interest in a Global Note that is a Transfer Restricted Security) pursuant to Rule 144 under the Securities Act or pursuant to an effective registration statement under the Securities Act: in the case of any Transfer Restricted Security that is a Definitive Note, the Registrar shall permit the Holder thereof to exchange such Transfer Restricted Security for a Definitive Note that does not bear the legend set forth in (i) above and rescind any restriction on the transfer of such Transfer Restricted Security, upon certification of the transferring Holder to the Registrar substantially in the form of Exhibit C hereto; and 20 in the case of any beneficial interest in a Global Note that is a Transfer Restricted Security, such interest shall be sold or transferred in compliance with the provisions of Section 2.06(c) hereof and the Global Note thereafter representing such interest shall not be required to bear the legend set forth in (i) above. Notwithstanding the foregoing, upon consummation of an Exchange Offer, the Company shall issue and the Trustee shall authenticate Series B Notes in exchange for Series A Notes, which Series B Notes shall not bear the legend set forth in (i) above, and the Registrar shall rescind any restriction on the transfer of such Series B Notes. Cancellation and/or Adjustment of Global Notes. At such time as all beneficial interests in Global Notes have been exchanged for Definitive Notes, redeemed, repurchased or canceled, all Global Notes shall be returned to or retained and canceled by the Trustee in accordance with Section 2.11 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for Definitive Notes or a beneficial interest in another Global Note, redeemed, repurchased or canceled, the principal amount of Notes represented by such Global Note shall be reduced accordingly and an endorsement shall be made on such Global Note, by the Trustee or the Note Custodian, at the direction of the Trustee, to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note shall be increased accordingly and an endorsement shall be made on such Global Note, by the Trustee or the Note Custodian, at the direction of the Trustee, to reflect such increase. General Provisions Relating to Transfers and Exchanges. To permit registrations of transfers and exchanges, subject to this Section 2.06, the Company shall execute and the Trustee shall authenticate Definitive Notes and Global Notes at the Registrar's request. No service charge shall be made to a Holder for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 3.07, 3.09, 4.10, 4.15 and 9.05 hereto). The Registrar shall not be required to register the transfer of or exchange any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part. All Definitive Notes and Global Notes issued upon any registration of transfer or exchange of Definitive Notes or Global Notes shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Definitive Notes or Global Notes surrendered upon such registration of transfer or exchange. The Company and the Registrar shall not be required: to issue, to register the transfer of or to exchange 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; or to register the transfer of or to exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part; or 21 to register the transfer of or to exchange a Note between a record date and the next succeeding interest payment date. 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, premium, if any, interest and Liquidated Damages, if any, on such Notes, and neither the Trustee, any Agent nor the Company shall be affected by notice to the contrary. 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 shall authenticate a replacement Note of the same series if the Trustee's requirements 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 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. 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, any of the Subsidiary Guarantors or any Affiliate of the Company or any of the Subsidiary Guarantors 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 bona fide 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 be deemed to be no date or maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes shall longer outstanding and shall cease to accrue interest. 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, any of the Subsidiary Guarantors or any Affiliate of the Company or any of the Subsidiary Guarantors, 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 actually knows are so owned shall be so disregarded. TEMPORARY NOTES. Until definitive Notes are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Notes upon a written order of the Company signed by two Officers thereof. Temporary Notes shall be substantially in the form of definitive Notes but may have variations that the Company considers appropriate for temporary Notes and as shall be reasonably acceptable to the Trustee. Without unreasonable delay, the Company 22 shall prepare and the Trustee shall authenticate definitive Notes in exchange for temporary Notes. Holders of temporary Notes shall be entitled to all of the benefits of this Indenture. 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 such canceled Notes. The Trustee shall provide a certificate of destruction to the Company from time to time, at the written request of 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. If the Company or any Subsidiary Guarantor shall acquire any of the Notes, such acquisition shall not operate as a redemption or satisfaction of the Indebtedness represented by such Securities unless and until the same are surrendered to the Trustee for cancellation pursuant to this Section 2.11. 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 shall 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. CUSIP NUMBERS. The Company in issuing the Notes may use "CUSIP" numbers (if then generally in use), and, if so, the Trustee shall use CUSIP numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company shall promptly notify the Trustee of any change in the CUSIP numbers. REDEMPTION AND PREPAYMENT NOTICES TO TRUSTEE. If the Company elects to redeem Notes pursuant to the optional redemption provisions of Section 3.07 hereof, it shall furnish to the Trustee, at least 30 days but not more than 60 days before a redemption date, an Officers' Certificate setting forth (i) the clause of this Indenture pursuant to which the redemption shall occur, (ii) the redemption date, (iii) the principal amount of Notes to be redeemed and (iv) the redemption price. SELECTION OF NOTES TO BE REDEEMED. If less than all of the Notes are to be redeemed at any time, the Trustee shall select the Notes to be redeemed among the Holders of the Notes in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed or, if the Notes are not so listed, on a pro rata basis, by lot or in accordance with any other method the Trustee considers fair and appropriate; provided that no Notes of $1,000 or less will be redeemed in part. In the event that less than all of the Notes are to be redeemed by lot, the particular 23 Notes to be redeemed shall be selected, unless otherwise provided herein, not less than 30 nor more than 60 days prior to the redemption date by the Trustee from the outstanding Notes not previously called for redemption. The Trustee shall promptly notify the Company in writing of the Notes selected for redemption and, in the case of any Note selected for partial redemption, the principal amount thereof to be redeemed. 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, the entire outstanding amount of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption. The provisions of the two preceding paragraphs of this Section 3.02 shall not apply with respect to any redemption affecting only a Global Note, whether such Global Note is to be redeemed in whole or in part. In case of any such redemption in part, the unredeemed portion of the principal amount of the Global Note shall be in an authorized denomination. NOTICE OF REDEMPTION. Subject to the provisions of Section 3.09 hereof, 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. Failure to receive such notice or any defect in the notice to any such Holder shall not affect the validity of the proceedings for the redemption of any other Notes or portion thereof. The notice shall identify the Notes to be redeemed (including CUSIP number) and shall state: the redemption date; the redemption price; 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; the name and address of the Paying Agent; that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price; that, unless the Company's defaults in making such redemption payment, interest on Notes called for redemption ceases to accrue on and after the redemption date; the paragraph of the Notes and/or Section of this Indenture pursuant to which the Notes called for redemption are being redeemed; and 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. If any of the Notes to be redeemed is in the form of a Global Note, then the Company shall modify such notice to the extent necessary to accord with the procedures of the Depository applicable to redemption. 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 shall have delivered to the Trustee, at least 60 days (unless the Trustee and the Company agree to a shorter period) prior to the redemption date, an Officers' 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. 24 EFFECT OF NOTICE OF REDEMPTION. Once notice of redemption is mailed 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. DEPOSIT OF REDEMPTION PRICE. Prior to 10:00 a.m. Eastern time on the redemption date, the Company shall deposit with the Trustee or with the Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 2.04 hereof) money sufficient to pay the redemption price of and accrued interest and Liquidated Damages, if any, on all Notes to be redeemed 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 price of, and accrued interest on, all Notes to be redeemed. If the Company complies with the provisions of the preceding paragraph, on and after the redemption date, interest shall cease to accrue on the Notes or the portions of Notes called for redemption. If a Note is redeemed 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 shall not be so paid upon surrender for redemption because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption 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 Note and in Section 4.01 hereof. NOTES REDEEMED IN PART. Upon surrender of a Note that is redeemed in part, the Company shall issue and the Trustee shall authenticate for the Holder at the expense of the Company a new Note equal in principal amount to the unredeemed portion of the Note surrendered. OPTIONAL REDEMPTION. The Notes will not be redeemable at the Company's option prior to November 15, 2004. Thereafter, the Notes will be subject to redemption at the option of the Company, in whole or in part, upon not less than 30 nor more than 60 days' notice, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest and Liquidated Damages thereon to the applicable redemption date, if redeemed during the twelve-month period beginning on November 15, of the years indicated below: <Table> <Caption> YEAR PERCENTAGE 2004......................................................................................................105.0625% 2005......................................................................................................103.3750% 2006......................................................................................................101.6875% 2007 and thereafter.......................................................................................100.0000% </Table> Any redemption pursuant to this Section 3.07 shall be made pursuant to the provisions of Section 3.01 through 3.06 hereof. MANDATORY REDEMPTION. Except as set forth under Sections 4.10 and 4.15 hereof, the Company shall not be required to make mandatory redemption or repurchase payments or sinking fund payments with respect to the Notes. 25 OFFER TO PURCHASE BY APPLICATION OF EXCESS PROCEEDS. In the event that, pursuant to Section 4.10 hereof, the Company shall be required to commence an Asset Sale Offer, it shall follow the procedures specified below. The Asset Sale Offer shall be made to all Holders and shall remain open for a period of 20 Business Days following its commencement and no longer, except to the extent that a longer period is required by applicable law (the "Offer Period"). If the Asset Sale Offer Purchase Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest and Liquidated Damages thereon, if any, shall be paid to the Person in whose name a Note is registered at the close of business on such record date, and no additional interest or Liquidated Damages shall be payable to Holders who tender Notes pursuant to the Asset Sale Offer. Within 10 days following any Asset Sale Offer Trigger Date, the Company shall send, by first class mail, a notice to each of the Holders at such Holder's registered address, with a copy to the Trustee. The notice, which shall govern the terms of the Asset Sale Offer, shall contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer, and shall state: that the Asset Sale Offer Trigger Date has occurred pursuant to Section 4.10 hereof and that the Company is offering to purchase the maximum principal of Notes that may be purchased out of the Excess Proceeds not applied to a Series D Asset Sale Offer (the "Offer Amount") at an offer price in cash in an amount equal to 100.0% of the principal amount thereof, plus accrued and unpaid interest and Liquidated Damages thereon, if any, to date of purchase, which shall be a Business Day (the "Asset Sale Offer Purchase Date") that is not earlier than 30 days nor later than 60 days from the date such notice is mailed; the amount of accrued and unpaid interest, if any, and unpaid Liquidated Damages, if any, as of the Asset Sale Offer Purchase Date; that any Note subject to the Asset Sale Offer not tendered shall continue to accrue interest; that, unless the Company defaults in the payment of the purchase price for the Notes payable pursuant to the Asset Sale Offer, any such Notes accepted for payment pursuant to the Asset Sale Offer shall cease to accrue interest, after the Asset Sale Offer Purchase Date; that Holders electing to have a Note purchased pursuant to an Asset Sale Offer may elect to have all of such Note purchased or they may elect to have only a portion of such Note purchased; that Holders electing to have a Note purchased pursuant to any Asset Sale Offer shall be required to surrender the Note, with the form entitled "Option of Holder to Elect Purchase" on the reverse of the Note completed to the Company or a Paying Agent at the address specified in the notice at least three days before the Asset Sale Offer Purchase Date; 26 that Holders shall be entitled to withdraw their election if the Company or the Paying Agent, as the case may be, receives, not later than the expiration of the Offer Period, a facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Note purchased; that, if the aggregate principal amount of Notes surrendered by Holders exceeds the Offer Amount or less than all of the Notes tendered pursuant to the Asset Sale Offer are accepted for payment by the Company for any reason consistent with this Indenture, the Trustee shall select the Notes to be purchased on a pro rata basis; provided that Notes accepted for payment in part will only be purchased in integral multiples of $1,000; and that Holders whose Notes were purchased only in part shall be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered. If any of the Notes subject to an Asset Sale Offer is in the form of a Global Note, then the Company shall modify such notice to the extent necessary to accord with the procedures of the Depository applicable to repurchases. On the Asset Sale Offer Purchase Date, the Company shall: (i) accept for payment the maximum principal amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer that can be purchased out of the Excess Proceeds; (ii) deposit with the Paying Agent the aggregate purchase price of all Notes or portions thereof accepted for payment; and (iii) deliver or cause to be delivered to the Trustee all Notes tendered pursuant to the Asset Sale Offer. The Company or the Paying Agent, as the case may be, shall promptly mail to each Holder of Notes or portions thereof accepted for payment an amount equal to the purchase price for such Notes and the Trustee shall promptly authenticate and mail to any such Holder of Notes accepted for payment in part a new Note equal in principal amount to any unpurchased portion of the Notes, and any Note not accepted for payment in whole or in part shall be promptly returned to the Holder of such Note. The Company shall announce the results of the Asset Sale Offer to Holders of the Notes on or as soon as practicable after the Asset Sale Offer Purchase Date. The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act, and any other securities laws or regulations, if applicable, in connection with any Asset Sale Offer. Other than as specifically provided in this Section 3.09, any purchase pursuant to this Section 3.09 shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof. COVENANTS PAYMENT OF NOTES. The Company shall pay or cause to be paid the principal of, premium, if any, and interest on the Notes on the dates and in the manner provided in the Notes. Principal, premium, if any, and interest shall be considered paid on the date due if the Paying Agent, if other than the Company or a Subsidiary thereof, holds as of 10:00 a.m. Eastern Time on the due date money deposited by the Company in immediately available funds and designated for and sufficient to pay all principal, premium, if any, and interest then due. The Company shall pay all Liquidated Damages, if any, in the same manner on the dates and in the amounts set forth in the applicable Registration Rights Agreement. The Company shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at the rate equal to 1.0% per annum in excess of the then applicable interest rate on the Notes to the extent lawful; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest and Liquidated Damages (without regard to any applicable grace period) at the same rate to the extent lawful. 27 MAINTENANCE OF OFFICE OR AGENCY. The Company shall maintain in the United States an office or agency (which may be an office of the Trustee or an affiliate of the Trustee, Registrar or co-registrar) where Notes may be presented for payment, surrendered for registration of transfer or for exchange and where notices and demands to or upon the Company in respect of the Notes and this Indenture may be served. The Company hereby designates the Corporate Trust Office of the Trustee as such office or agency of the Company in accordance with Section 2.03 hereof. The Company shall give prompt written notice to the Trustee of any change in the location of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee. The Company may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations. 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. REPORTS. Whether or not required by the rules and regulations of the Commission, so long as any Notes are outstanding, the Company shall furnish to the Holders of Notes (i) all quarterly and annual financial information that would be required to be contained in a filing with the Commission on Forms 10-Q and 10-K if the Company were required to file such Forms, including a "Management's Discussion and Analysis of Financial Condition and Results of Operations" that describes the consolidated financial condition and results of operations of the Company and, with respect to the annual information only, a report thereon by the Company's certified independent accountants and (ii) all information that would be required to be contained in a filing with the Commission on Form 8-K if the Company were required to file such Forms. In addition, whether or not required by the rules and regulations of the Commission, the Company shall file a copy of all such information and reports with the Commission for public availability (unless the Commission will not accept such a filing) and make such information available to securities analysts and prospective investors upon request. The Company shall at all times comply with TIA Section 314(a). For so long as any Transfer Restricted Securities remain outstanding, the Company shall furnish to all Holders and prospective purchasers of the Notes designated by the Holders of Transfer Restricted Securities, promptly upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act. Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee's receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company' compliance with any of the covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers' Certificates). COMPLIANCE CERTIFICATE. The Company shall deliver to the Trustee, within 90 days after the end of each fiscal year, an Officers' Certificate stating that a review of the activities of the Company and its Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether the Company has kept, observed, performed and fulfilled its obligations under this Indenture, and further stating, as to each such Officer signing such certificate, that to the best of his or her knowledge the Company has kept, observed, performed and fulfilled each and every covenant contained in this Indenture and is not in default in the performance or observance of any of the terms, provisions and conditions of this Indenture (or, if a Default or Event of Default shall have occurred and is continuing, describing all such Defaults or Events of Default of which he or she may have knowledge and what action the Company is taking or proposes to take with respect thereto) and that to the best of his or her knowledge no event has occurred and remains in existence by reason of which payments on account of the principal of or interest, if any, on the Notes is prohibited or if such event has occurred, a description of the event and what action the Company is taking or proposes to take with respect thereto. 28 So long as not contrary to the then current recommendations of the American Institute of Certified Public Accountants, the year-end financial statements delivered pursuant to Section 4.03(a) above shall be accompanied by a written statement of the Company' independent public accountants (who shall be a firm of established national reputation) that in making the examination necessary for certification of such financial statements, nothing has come to their attention that would lead them to believe that the Company has violated any provisions of Article 4 or Article 5 hereof or, if any such violation has occurred, specifying the nature and period of existence thereof, it being understood that such accountants shall not be liable directly or indirectly to any Person for any failure to obtain knowledge of any such violation. The Company shall, so long as any of the Notes are outstanding, deliver to the Trustee, forthwith upon any Officer becoming aware of any Default or Event of Default, an Officers' Certificate specifying such Default or Event of Default and what action the Company is taking or proposes to take with respect thereto. TAXES. The Company shall pay, and shall cause each of its Subsidiaries to pay, prior to delinquency, all material taxes, assessments, and governmental levies except such as are contested in good faith and by appropriate proceedings or where the failure to effect such payment is not adverse in any material respect to the Holders of the Notes. STAY, EXTENSION AND USURY LAWS. The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it shall not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law has been enacted. RESTRICTED PAYMENTS. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly: (i) declare or pay any dividend or make any other payment or distribution on account of the Company's or any of its Restricted Subsidiaries' Equity Interests (including, without limitation, any payment in connection with any merger or consolidation involving the Company) or to the direct or indirect holders of the Company's Equity Interests in their capacity as such (other than dividends or distributions payable in Equity Interests (other than Disqualified Stock) of the Company or dividends or distributions payable to the Company or any Wholly Owned Restricted Subsidiary of the Company); (ii) purchase, redeem or otherwise acquire or retire for value any Equity Interests of the Company or any Affiliate of the Company (other than (A) any such Equity Interests owned by the Company or any Wholly Owned Restricted Subsidiary of the Company that is a Subsidiary Guarantor and (B) Employee Stock Repurchases); (iii) make any principal payment on, or purchase, redeem, defease or otherwise acquire or retire for value any Subordinated Indebtedness, except in accordance with the mandatory redemption or repayment provisions set forth in the original documentation governing such Indebtedness; or (iv) make any Restricted Investment (all such payments and other actions set forth in clauses (i) through (iv) above being collectively referred to as "Restricted Payments"), unless, at the time of and after giving effect to such Restricted Payment: no Default or Event of Default shall have occurred and be continuing or would occur as a consequence thereof; the Company would, at the time of such Restricted Payment and after giving pro forma effect thereto as if such Restricted Payment had been made at the beginning of the applicable four-quarter period, have been permitted to incur at least $1.00 of additional Indebtedness (other than Permitted Indebtedness) pursuant to the Fixed Charge Coverage Ratio test set forth in the first paragraph of Section 4.09 hereof; and 29 such Restricted Payment, together with the aggregate of all other Restricted Payments made by the Company and its Restricted Subsidiaries after the Series A/B Issue Date (excluding Restricted Payments permitted by clauses (w), (y) and (z) of the next succeeding paragraph) is less than the sum of (i) 50% of the Consolidated Net Income of the Company for the period (taken as one accounting period) from the beginning of the first fiscal quarter commencing after the Series A/B Issue Date to the end of the Company's most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted Payment (or, if such Consolidated Net Income for such period is a deficit, less 100% of such deficit), plus (ii) 100% of the aggregate Net Equity Proceeds (A) received by the Company from the issue or sale, subsequent to the Series A/B Issue Date, of Qualified Capital Stock of the Company or (B) of any other Equity Interests or debt securities of the Company that have been issued subsequent to the Series A/B Issue Date and that have been converted into such Qualified Capital Stock (other than any Qualified Capital Stock sold to a Restricted Subsidiary of the Company or issued upon conversion of the Convertible Preferred Stock), plus (iii) to the extent not otherwise included in Consolidated Net Income, the net reduction in Investments in Unrestricted Subsidiaries and Affiliates resulting from dividends, repayments of loans or advances, or other transfers of assets (including reductions in guarantees), in each case to the Company or a Restricted Subsidiary after the Series A/B Issue Date from any Unrestricted Subsidiary or Affiliate or from the redesignation of an Unrestricted Subsidiary as a Restricted Subsidiary (valued as provided below), plus (iv) $15 million. The foregoing provisions shall not prohibit any of the following: (w) any purchase, redemption or other acquisition or retirement, in each case at a price less than par, of up to $75 million in aggregate principal amount of the Company's 5 1/2% Convertible Subordinated Notes due 2004, prior to their stated maturity; (x) the payment of any dividend within 60 days after the date of declaration thereof, if at said date of declaration such payment would have complied with the provisions of this Indenture; (y) the redemption, repurchase, retirement or other acquisition of any Equity Interests of the Company in exchange for, or out of the Net Equity Proceeds of, the substantially concurrent sale (other than to a Restricted Subsidiary of the Company) of Qualified Capital Stock of the Company (other than any Disqualified Stock); provided that the amount of any such Net Equity Proceeds that are utilized for any such redemption, repurchase, retirement or other acquisition shall be excluded from clause (c)(ii) of the preceding paragraph and (z) the defeasance, redemption or repurchase of Subordinated Indebtedness with the net cash proceeds from an incurrence of Permitted Refinancing Indebtedness or the substantially concurrent sale (other than to a Restricted Subsidiary of the Company) of Qualified Capital Stock of the Company; provided that the amount of any such net cash proceeds that are utilized for any such redemption, repurchase, retirement or other acquisition shall be excluded from clause (c)(ii) of the preceding paragraph. For purposes of the foregoing provisions, the amount of any Restricted Payment (other than cash) shall be the fair market value (evidenced by a resolution of the Board of Directors set forth in an Officers' Certificate delivered to the Trustee) on the date of the Restricted Payment of the asset(s) proposed to be transferred by the Company or such Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment. Not later than the date of making any Restricted Payment, the Company shall deliver to the Trustee an Officers' Certificate stating that such Restricted Payment is permitted and setting forth the basis upon which the calculations required by this Section 4.07 were computed, which calculations may be based upon the Company's latest available financial statements. The Board of Directors may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if such designation would be permitted by the provisions of this Section 4.07 and if such Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. For purposes of making such determination, all outstanding Investments by the Company and its Restricted Subsidiaries (except to the extent repaid in cash prior to such designation) in the Restricted Subsidiary so designated will be deemed to be Restricted Payments at the time of such designation and will reduce the amount available for Restricted Payments under the paragraph (c) of this Section 4.07. All such outstanding Investments will be deemed to constitute Investments in an amount equal to the Fair Market Value of such Investments at the time of such designation. DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING SUBSIDIARIES. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to exist or become effective any encumbrance or restriction on the ability of any Restricted Subsidiary to (i)(a) pay dividends or make any other distributions to the Company or any of its Restricted Subsidiaries (1) on its Capital Stock or (2) with respect to any other interest or participation in, or measured by, its 30 profits, or (b) pay any indebtedness owed to the Company or any of its Restricted Subsidiaries; (ii) make loans or advances to the Company or any of its Restricted Subsidiaries; or (iii) transfer any of its properties or assets to the Company or any of its Restricted Subsidiaries, except for such encumbrances or restrictions existing under or by reason of (r) Existing Indebtedness as in effect on the Series A/B Issue Date, (s) the Senior Credit Facility as in effect as of the Series A/B Issue Date, and any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings thereof, provided that such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacement or refinancings are no more restrictive with respect to such dividend and other payment restrictions than those contained in the Senior Credit Facility as in effect on the Series A/B Issue Date, (t) this Indenture, the Series D Indenture, the Notes, and the Series D Notes, (u) applicable law, (v) any instrument governing Indebtedness or Capital Stock of a Person acquired by the Company or any of its Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired, provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of the Series D Indenture and this Indenture to be incurred, (w) by reason of customary non-assignment provisions in leases entered into in the ordinary course of business and customary provisions in other agreements that restrict assignment of such agreements or rights thereunder, (x) customary restrictions contained in asset sale agreements limiting the transfer of such assets pending the closing of such sale, (y) purchase money obligations for property acquired in the ordinary course of business that impose restrictions of the nature described in clause (iii) above on the property so acquired, or (z) Permitted Refinancing Indebtedness with respect to any indebtedness referred to in clauses (r), (t) and (v) above, provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are no more restrictive than those contained in the agreements governing the Indebtedness being refinanced. INCURRENCE OF INDEBTEDNESS AND ISSUANCE OF PREFERRED EQUITY. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, continentally or otherwise, with respect to (collectively, "incur") any Indebtedness (including Acquired Indebtedness but excluding any Permitted Indebtedness) and that the Company will not issue any Disqualified Stock and will not permit any of its Restricted Subsidiaries to issue any shares of preferred stock; provided, however, that the Company may incur Indebtedness (including Acquired Indebtedness) or issue shares of Disqualified Stock, and any Restricted Subsidiary may incur Indebtedness (including Acquired Indebtedness), if the Fixed Charge Coverage Ratio for the Company's most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock is issued would have been at least 2.0 to 1.0, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred, or the Disqualified Stock had been issued, as the case may be, at the beginning of such four-quarter period. The Company shall not , and shall not permit any Subsidiary Guarantor to, directly or indirectly, in any event incur any Indebtedness that by its terms (or by the terms of any agreement governing such Indebtedness) is subordinated to any other Indebtedness of the Company or such Subsidiary Guarantor, as the case may be, unless such Indebtedness is also by its terms (or by the terms of any agreement governing such Indebtedness) made expressly subordinate to the Notes or the Subsidiary Guarantee of such Subsidiary Guarantor, as the case may be, to the same extent and in the same manner as such Indebtedness is subordinated pursuant to subordination provisions that are most favorable to the holders of any other Indebtedness of the Company or such Subsidiary Guarantor, as the case may be. ASSET SALES. The Company shall not, and shall not permit any Restricted Subsidiary to, sell, issue, convey, transfer, lease or otherwise dispose of, to any Person other than the Company or any of its Restricted Subsidiaries (including, without limitation, by means of a sale-and-leaseback transaction or a merger or consolidation) (collectively, for purposes of this Section 4.10, a "transfer"), directly or indirectly, in one or a series of related transactions, (a) any Capital Stock of any Restricted Subsidiary held by the Company or any other Restricted Subsidiary, (b) all or substantially all of the properties and assets of any division or line of business of the Company or any of its 31 Restricted Subsidiaries, (c) any Event of Loss or (d) any other properties or assets of the Company or any of its Restricted Subsidiaries other than transfers of cash, Cash Equivalents, accounts receivable, or properties or assets in the ordinary course of business; provided that the sale, lease, conveyance or other disposition of all or substantially all of the properties or assets of the Company and its Restricted Subsidiaries, taken as a whole, shall be governed by Sections 4.15 and/or 5.01 and not by the provisions of this Section 4.10 (each of the foregoing, an "Asset Sale"), unless (i) the Company (or the Restricted Subsidiary, as the case may be) receives consideration at the time of such Asset Sale at least equal to the fair market value (evidenced by a resolution of the Board of Directors set forth in an Officers' Certificate delivered to the Trustee) of the assets or Equity Interests issued or sold or otherwise disposed of and (ii) at least 75% of the consideration therefor received by the Company or such Restricted Subsidiary is in the form of cash or Cash Equivalents; provided that the amount of (x) any liabilities (as shown on the Company's or such Restricted Subsidiary's most recent balance sheet) of the Company or any Restricted Subsidiary (other than contingent liabilities and liabilities that are Subordinated Indebtedness or otherwise by their terms subordinated to the Notes or the Subsidiary Guarantees) that are assumed by the transferee of any such assets pursuant to a customary novation agreement that releases the Company or such Restricted Subsidiary from further liability and (y) any notes or other obligations received by the Company or any such Restricted Subsidiary from such transferee that are converted by the Company or such Restricted Subsidiary into cash within 180 days of closing such Asset Sale (to the extent of the cash received) shall be deemed to be cash for purposes of this clause (ii) and provided further, that the Company may engage in the transfer of properties or assets, including two drilling rigs and related inventories and equipment and a contract with Tengizchevroil, to AralParker CJSC in consideration of a note payable by AralParker CJSC in a principal amount of up to $50 million. Notwithstanding the foregoing, any of the following shall not be deemed an "Asset Sale": (i) any transfer of properties or assets to an Unrestricted Subsidiary, if such transfer is permitted under Section 4.07 hereof; (ii) sales of damaged, worn-out or obsolete equipment or assets that, in the Company's reasonable judgment, are either (A) no longer used or (B) no longer useful in the business of the Company or its Restricted Subsidiaries; (iii) any lease of any property entered into in the ordinary course of business and with respect to which the Company or any Restricted Subsidiary is the lessor, except any such lease that provides for the acquisition of such property by the lessee during or at the end of the term thereof for an amount that is less than the fair market value thereof at the time the right to acquire such property is granted; (iv) any trade or exchange by the Company or any Restricted Subsidiary of one or more drilling rigs for one or more other drilling rigs owned or held by another Person, provided that (A) the Fair Market Value of the drilling rig or rigs traded or exchanged by the Company or such Restricted Subsidiary (including any cash or Cash Equivalents to be delivered by the Company or such Restricted Subsidiary) is reasonably equivalent to the Fair Market Value of the drilling rig or rigs (together with any cash or Cash Equivalents) to be received by the Company or such Restricted Subsidiary and (B) such exchange is approved by a majority of the Disinterested Directors of the Company; (v) any transfer by the Company or any Restricted Subsidiary to its customers of drill pipe, tools and associated drilling equipment utilized in connection with a drilling contract for the employment of a drilling rig in the ordinary course of business and consistent with past practice; and (vi) any transfers that, but for this clause (vi), would be Asset Sales, if (A) the Company elects to designate such transfers as not constituting Asset Sales and (B) after giving effect to such transfers, the aggregate Fair Market Value of the properties or assets transferred in such transaction or any such series of related transactions so designated by the Company does not exceed $500,000. Within 365 days after the receipt of any Net Proceeds from any Asset Sale, the Company may (i) apply all or any of the Net Proceeds therefrom to repay Indebtedness (other than Subordinated Indebtedness) of the Company or any Restricted Subsidiary, provided, in each case, that the related loan commitment of any revolving credit facility or other borrowing (if any) is thereby permanently reduced by the amount of such Indebtedness so repaid, or (ii) invest all or any part of the Net Proceeds thereof in properties and other capital assets that replace the properties or other capital assets that were the subject of such Asset Sale or in other properties or other capital assets that will be used in the business of the Company and its Restricted Subsidiaries. Pending the final application of any such Net Proceeds, the Company may temporarily reduce borrowings under any revolving credit facility or otherwise invest such Net Proceeds in any manner that is not prohibited by this Indenture. Any Net Proceeds from Asset Sales that are not applied or invested as provided in the first sentence of this paragraph shall be deemed to constitute "Excess Proceeds." When the aggregate amount of Excess Proceeds equals or exceeds $15 million (the date of such occurrence being called the "Asset Sale Offer Trigger Date"), the Company shall (i) make an offer to purchase ("Series D Asset Sale Offer") the Series D Notes, if any are then outstanding, at a price equal to 100% of the principal amount of the Series D Notes, plus accrued and unpaid interest to the date of purchase and (ii) in the event 32 that any Excess Proceeds are not applied to a Series D Asset Sale Offer, to make an offer to all Holders of Notes (an "Asset Sale Offer") to purchase the maximum principal amount of Notes that may be purchased out of such Excess Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount thereof, plus accrued and unpaid interest and Liquidated Damages thereon to the date of purchase, in accordance with the procedures set forth in Section 3.09 hereof. To the extent that the aggregate amount of Series D Notes and Notes tendered pursuant to a Series D Asset Sale Offer and an Asset Sale Offer, respectively, is less than the Excess Proceeds, the Company may use any remaining Excess Proceeds for general corporate purposes. Upon completion of such Asset Sale Offer, the amount of Excess Proceeds shall be deemed to be reset at zero. The Company shall not permit any Restricted Subsidiary to enter into or suffer to exist any agreement (other than the Series D Indenture) that would place any restriction of any kind (other than pursuant to law or regulation) on the ability of the Company to make an Asset Sale Offer following any Asset Sale. The Company shall comply with Rule 14e-1 under the Exchange Act, and any other securities laws and regulations thereunder, if applicable, in the event that an Asset Sale occurs and the Company is required to purchase Notes pursuant to this Section 4.10. TRANSACTIONS WITH AFFILIATES. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, (a) sell, lease, transfer or otherwise dispose of any of its properties, assets or securities to, (b) purchase or lease any property, assets or securities from, (c) make any Investment in, or (d) enter into or suffer to exist any other transaction or series of related transactions with, or for the benefit of, any Affiliate of the Company unless (i) such transaction or series of transactions is on terms that are no less favorable to the Company or such Restricted Subsidiary, as the case may be, than those that would be available in a comparable arm's length transaction with an unrelated third party, (ii) with respect to any one transaction or series of related transactions involving aggregate payments in excess of $1 million, the Company delivers an Officers' Certificate to the Trustee certifying that such transaction or series of related transactions complies with clause (i) above, and (iii) with respect to a transaction or series of related transactions involving payments in excess of $5 million, the Company delivers an Officers' Certificate to the Trustee certifying that (A) such transaction or series of related transactions complies with clause (i) above and (B) such transaction or series of related transactions has been approved by a majority of the Disinterested Directors of the Company; provided, however, that the foregoing restriction shall not apply to (u) any arrangements in effect on the Series A/B Issue Date, (v) transactions between or among the Company and its Wholly Owned Restricted Subsidiaries, (w) loans or advances to officers, directors and employees of the Company or any Restricted Subsidiary made in the ordinary course of business and consistent with past practices of the Company and its Restricted Subsidiaries in an aggregate amount not to exceed $1 million outstanding at any one time, (x) indemnities of officers, directors and employees of the Company or any Restricted Subsidiary permitted by bylaw or statutory provisions, (y) the payment of reasonable and customary regular fees to directors of the Company or any of its Restricted Subsidiaries who are not employees of the Company or any Affiliate and (z) the Company's employee compensation and other benefit arrangements. LIENS. The Company shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, create, incur, assume, affirm or suffer to exist or become effective any Lien of any kind, except for Permitted Liens, upon any of their respective property or assets, whether now owned or acquired after the Issue Date, or any income, profits or proceeds therefrom, to secure (i) any Indebtedness of the Company or such Restricted Subsidiary (if it is not also a Subsidiary Guarantor), unless prior to, or contemporaneously therewith, the Notes are equally and ratably secured, or (ii) any Indebtedness of any Subsidiary Guarantor, unless prior to, or contemporaneously therewith, the Subsidiary Guarantees are equally and ratably secured; provided, however, that if such Indebtedness is expressly subordinated to the Notes or the Subsidiary Guarantees, the Lien securing such Indebtedness will be subordinated and junior to the Lien securing the Notes or the Subsidiary Guarantees, as the case may be, with the same relative priority as such Indebtedness has with respect to the Notes or the Subsidiary Guarantees. The foregoing covenant shall not apply to any Lien securing Acquired Indebtedness, provided that any such Lien extends only to the property or assets that were subject to such Lien prior to the related acquisition by the Company or such Restricted Subsidiary and was not created, incurred or assumed in contemplation of such transaction. 33 ISSUANCES AND SALES OF CAPITAL STOCK OF WHOLLY OWNED SUBSIDIARIES.

SUCCESSORS MERGER, CONSOLIDATION, OR SALE OF ASSETS. The Company shall not consolidate or merge with or into (whether or not the Company is the surviving corporation), or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets in one or more related transactions, to another Person unless (i) the Company is the surviving corporation or the Person formed by or surviving any such consolidation or merger (if other than the Company) or to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made is a corporation organized or existing under the laws of the United States, any state thereof or the District of Columbia; (ii) the Person formed by or surviving any such consolidation or merger (if other than the Company) or the Person to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made assumes all the obligations of the Company under the Notes and this Indenture pursuant to a supplemental indenture in a form reasonably satisfactory to the Trustee; (iii) except in the case of a merger of the Company with or into a Wholly Owned Subsidiary of the Company, immediately after such transaction no Default or Event of Default exists; and (iv) except in the case of a merger of the Company with or into a Wholly Owned Subsidiary of the Company, the Company or the Person formed by or surviving any such consolidation or merger (if other than the Company), or to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made (A) will have Consolidated Net Worth immediately after the transaction equal to or greater than the Consolidated Net Worth of the Company immediately preceding the transaction and (B) will, at the time of such transaction and after giving pro forma effect thereto as if such transaction had occurred at the beginning of the applicable four-quarter period, be permitted to incur at least $1.00 of additional Indebtedness (other than Permitted Indebtedness) pursuant to the Fixed Charge Coverage Ratio test set forth in the first paragraph of Section 4.09 hereof.

An "Event of Default" occurs if: the Company defaults for 30 days in the payment when due of interest on, or Liquidated Damages with respect to, the Notes; the Company defaults in payment of the principal of or premium, if any, on the Notes when the same becomes due and payable at stated maturity, upon redemption (including in connection with an offer to purchase) or otherwise; the Company fails to comply with the provisions of Section 4.10, 4.15 or 5.01 hereof; the Company fails for 45 days after notice to the Company by the Trustee or the Holders at least 25% in aggregate principal amount of the Notes then outstanding to comply with any of its other agreements in this Indenture or the Notes; the Company or any of its Restricted Subsidiaries defaults under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries) whether such Indebtedness or guarantee now exists, or is created after the Issue Date, which default (A) is caused by a failure to pay principal of or premium, if any, or interest on such Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of such default (a "Payment Default") or (B) results in the acceleration of such Indebtedness prior to its express maturity and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $7.5 million or more; a final judgment or final judgments for the payment of money are entered by a court or courts of competent jurisdiction against the Company or any of its Subsidiaries and such judgment or judgments remain unpaid and undischarged for a period (during which execution shall not be effectively stayed) of 60 consecutive days, provided that the aggregate of all such unpaid and undischarged judgments exceeds $10 million; any Subsidiary Guarantee shall for any reason cease to be, or be asserted by the Company or any Subsidiary Guarantor, as applicable, not to be, in full force and effect (except pursuant to the release of any Subsidiary Guarantee in accordance with this Indenture); the Company or any of its Restricted Subsidiaries that constitutes a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary, pursuant to or within the meaning of Bankruptcy Law: commences a voluntary case, consents to the entry of an order for relief against it in an involuntary case, 36 consents to the appointment of a Bankruptcy Custodian of it or for all or substantially all of its property, makes a general assignment for the benefit of its creditors, or generally is not paying its debts as they become due; or a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: is for relief, in an involuntary case, against the Company or any of its Restricted Subsidiaries that constitutes a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary; appoints a Bankruptcy Custodian of the Company or any of its Restricted Subsidiaries that constitutes a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary, for all or substantially all of the property of the Company or any of such Restricted Subsidiaries; or orders the liquidation of the Company or any of its Restricted Subsidiaries that constitutes a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary, for all or substantially all of the property of the Company or any of such Restricted Subsidiaries; and the order or decree remains unstayed and in effect for 60 consecutive days. ACCELERATION. If any Event of Default (other than an Event of Default specified in clause (viii) or (ix) of Section 6.01 hereof with respect to the Company or any of its Restricted Subsidiaries that constitutes a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary) occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately. Upon any such declaration, the Notes shall become due and payable immediately. Notwithstanding the foregoing, if an Event of Default specified in clause (viii) or (ix) of Section 6.01 hereof occurs with respect to the Company or any of its Restricted Subsidiaries that constitutes a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary, all outstanding Notes shall be due and payable immediately without further action or notice. The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may on behalf of all of the Holders waive any existing Default or Event of Default acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except nonpayment of principal, interest or premium that has become due solely because of the acceleration) have been cured or waived. 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 37 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. 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 interest on, or the principal of, the Notes (including in connection with an offer to purchase). 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. CONTROL BY MAJORITY. Holders of a majority in aggregate 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. LIMITATION ON SUITS. A Holder of a Note may pursue a remedy with respect to this Indenture or the Note only if: the Holder of a Note gives to the Trustee written notice of a continuing Event of Default; the Holders of at least 25% in aggregate principal amount of the then outstanding Notes make a written request to the Trustee to pursue the remedy; such Holder of a Notes or Holders of Notes offer and, if requested, provide to the Trustee indemnity satisfactory to the Trustee against any loss, liability or expense; 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 during such 60-day period the Holders of a majority in aggregate 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. 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 and Liquidated Damages, 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. 38 COLLECTION SUIT BY TRUSTEE. If an Event of Default specified in Section 6.01(i) or (ii) 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 and Liquidated Damages, 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. 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. 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, Liquidated Damages, 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 and Liquidated Damages, 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. 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 and expenses, 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 39 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 aggregate principal amount of the then outstanding Notes. TRUSTEE DUTIES OF TRUSTEE. If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in its exercise, as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs. Except during the continuance of an Event of Default: the duties of the Trustee shall be determined solely by the express provisions of this Indenture and the Trustee need perform only those duties that are specifically set forth in this Indenture and no others, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, in the case of any such certificates or opinions that by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture. The Trustee may not be relieved from liabilities for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that: this paragraph does not limit the effect of paragraph (b) of this Section 7.01; the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05 hereof. Whether or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b) and (c) of this Section 7.01. No provision of this Indenture shall require the Trustee to expend or risk its own funds or incur any liability. The Trustee shall be under no obligation to exercise any of its rights and powers under this Indenture at the request of any Holders, unless such Holder shall have offered to the Trustee security and indemnity satisfactory to it against any loss, liability or expense. The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. 40 RIGHTS OF TRUSTEE. The Trustee may conclusively rely upon any document believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document. Before the Trustee acts or refrains from acting, it may require an Officers' Certificate or an Opinion of Counsel or both. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such Officers' Certificate or Opinion of Counsel. The Trustee may consult with counsel of its selection and the advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection from liability in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon. The Trustee may act through its attorneys and agents and shall not be responsible for the misconduct or negligence of any agent appointed with due care. The Trustee shall not be liable for any action it takes or omits to take in good faith that it believes to be authorized or within the rights or powers conferred upon it by this Indenture.

The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders unless such Holders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities that might be incurred by it in compliance with such request or direction. INDIVIDUAL RIGHTS OF TRUSTEE. The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company or any Affiliate of the Compete with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest it must eliminate such conflict within 90 days, apply to the Commission for permission to continue as trustee or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof. TRUSTEE'S DISCLAIMER.

NOTICE OF DEFAULTS. If a Default or Event of Default occurs and is continuing and if it is known to the Trustee, the Trustee shall mail to Holders of Notes a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, premium, if any, or interest on any Notes, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of the Notes. REPORTS BY TRUSTEE TO HOLDERS OF THE NOTES. Within 60 days after each May 15 beginning with the May 15 following the date of this Indenture, and for so long as Notes remain outstanding, the Trustee shall mail to the Holders of the Notes a brief report dated as of 41 such reporting date that complies with TIA Section 313(a) (but if no event described in TIA Section 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also shall comply with TIA Section 313(b)(2) and Section 313(b)(1). The Trustee shall also transmit by mail all reports as required by TIA Section 313(c). A copy of each report at the time of its mailing to the Holders of Notes shall be mailed to the Company and filed with the Commission and each stock exchange on which the Notes are listed in accordance with TIA Section 313(d). The Company shall promptly notify the Trustee when the Notes are listed on any stock exchange. COMPENSATION AND INDEMNITY. The Company shall pay to the Trustee from time to time such compensation as shall be agreed between the Company and the Trustee for its acceptance of this Indenture and services hereunder. The Trustee's compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee's agents and counsel.

The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel and the Company shall pay the reasonable fees and expenses of such counsel. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. The obligations of the Company under this Section 7.07 shall survive the satisfaction and discharge of this Indenture. To secure the Company's payment obligations in this Section 7.07, the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal, premium and Liquidated Damages, if any, and interest on particular Notes. Such Lien shall survive the satisfaction and discharge of this Indenture. When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(viii) or (ix) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law. The Trustee shall also be entitled to receive compensation for extraordinary services in default administration. The Trustee shall comply with the provisions of TIA Section 313(b)(2) to the extent applicable. REPLACEMENT OF TRUSTEE.

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in aggregate principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Company. If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company, or the Holders of Notes of at least 10% in aggregate principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee. If the Trustee, after written request by any Holder of a Note who has been a Holder of a Note for at least six months, fails to comply with Section 7.10 hereof, such Holder of a Note may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders of the Notes. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Company's obligations under Section 7.07 hereof shall continue for the benefit of the retiring Trustee. SUCCESSOR TRUSTEE BY MERGER, ETC. If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to another corporation, the successor corporation without any further act shall be the successor Trustee. As soon as practicable, the successor Trustee shall mail a notice of its succession to the Company and the Holders of the Notes. ELIGIBILITY; DISQUALIFICATION.

PREFERENTIAL COLLECTION OF CLAIMS AGAINST THE COMPANY. The Trustee is subject to TIA Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee who has resigned or been removed shall be subject to TIA Section 311(a) to the extent indicated therein. 43 LEGAL DEFEASANCE AND COVENANT DEFEASANCE OPTION TO EFFECT LEGAL DEFEASANCE OR COVENANT DEFEASANCE.

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 and each Subsidiary Guarantor shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from its 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 (i) and (ii) below, and the Company and each Subsidiary Guarantor shall be deemed to have satisfied all of its other obligations under such Notes or Subsidiary Guarantee 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: (i) the rights of Holders of outstanding Notes to receive solely from the trust fund described in Section 8.04 hereof, and as more fully set forth in such Section, payments in respect of the principal of, premium, if any, and interest and Liquidated Damages on such Notes when such payments are due; (ii) the Company's obligations with respect to such Notes under Article 2 and Section 4.02 hereof; (iii) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Company's obligations in connection therewith; and (iv) this Article 8. Subject to compliance with this Article 8, the Company may exercise its option under this Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 hereof. COVENANT DEFEASANCE. Upon the Company's exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Company shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from its obligations under the covenants contained in Sections 4.05, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14, 4.15 and 4.16 hereof, clause (iv) of Section 5.01 hereof and Article 10 hereof with respect to the outstanding Notes on and after the date the conditions set forth below are satisfied (hereinafter, "Covenant Defeasance"), and the Notes shall thereafter be deemed not "outstanding" for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed "outstanding" for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Company and any Subsidiary Guarantor 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(iii) through 6.01(vii) hereof shall not constitute Events of Default. CONDITIONS TO LEGAL OR COVENANT DEFEASANCE. The following shall be the conditions to the application of either Section 8.02 or 8.03 hereof to the outstanding Notes: In order to exercise either Legal Defeasance or Covenant Defeasance: 44 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 will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, premium, if any, and interest and Liquidated Damages 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 the Notes are being defeased to maturity or to a particular redemption date; in the case of an election under Section 8.02 hereof, the Company shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that (i) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (ii) 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 will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will 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; in the case of an election under Section 8.03 hereof, the Company shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that the holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will 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; 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 incurrence of Indebtedness all or a portion of the proceeds of which will be used to defease the Notes pursuant to this Article 8 concurrently with such incurrence) or insofar as Section 6.01(viii) or 6.01(ix) hereof is concerned, at any time in the period ending on the 91st day after the date of deposit; 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 or the Series D 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; the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that, as of the date such opinion, (i) the trust funds will not be subject to rights of holders of Indebtedness other than the Notes and (ii) assuming no intervening bankruptcy of the Company between the date of deposit and the 91st day following the deposit (assuming no Holder of Notes is an insider of the Company) or the day following the end of such other preference period in effect at the time of such opinion (assuming a Holder of Notes is an insider of the Company), as applicable, following the deposit, the trust funds will not be subject to the effects of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors' rights generally under any applicable United States or state law; the Company shall have delivered to the Trustee an Officers' Certificate stating that the deposit was not made by the Company with the intent of preferring the holders of Notes over any other creditors of the Company or any Subsidiary Guarantor with the intent of defeating, hindering, delaying or defrauding creditors of the Company, or any Subsidiary Guarantor or others; and the Company shall have delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, which, taken together, state that all conditions precedent provided for or relating to the Legal Defeasance or the Covenant Defeasance have been complied with. 45 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 and Liquidated Damages, 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. Anything in this Article 8 to the contrary notwithstanding, 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 that, in the opinion of a nationally recognized 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(a) 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. REPAYMENT TO THE COMPANY. Subject to the applicable escheat and abandoned property laws, 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 or Liquidated Damages on any Note and remaining unclaimed for two years after such principal, and premium, if any, or interest or Liquidated Damages 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 Notes shall thereafter, as a secured creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, 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 will be repaid to the Company. REINSTATEMENT. If the Trustee or Paying Agent is unable to apply any United States dollars or non-callable Government Securities in accordance with Section 8.05 hereof 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 8.05 hereof; provided, however, that, if the Company makes any payment of principal of, premium, if any, or interest or Liquidated Damages 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. 46 AMENDMENT, SUPPLEMENT AND WAIVER WITHOUT CONSENT OF HOLDERS OF NOTES. Notwithstanding Section 9.02 of this Indenture, the Company, the Subsidiary Guarantors and the Trustee may amend or supplement this Indenture or the Notes without the consent of any Holder of a Note: to cure any ambiguity, defect or inconsistency; to provide for uncertificated Notes in addition to or in place of certificated Notes; to provide for the assumption of the Company's obligations to the Holders of the Notes pursuant to Article 5 or Section 10.04(b) hereof; to secure the Notes pursuant to the requirements of Section 4.12 or otherwise; to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights under this Indenture of any such Holder; to add any Restricted Subsidiary as an additional Subsidiary Guarantor as provided in Section 10.02 hereof or to evidence the succession of another Person to any Subsidiary Guarantor pursuant to Section 10.04 hereof and the assumption by any such successor of the covenants and agreements of such Subsidiary Guarantor contained herein and in the Subsidiary Guarantee of such Subsidiary Guarantor; to release a Subsidiary Guarantor from its obligations under this Indenture and its Subsidiary Guarantee pursuant to Section 10.05 hereof; to secure the Notes pursuant to the requirements of Section 4.12 hereof; or to comply with requirements of the Commission in order to effect or maintain the qualification of this Indenture under the TIA. 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 9.06 hereof, the Trustee shall join with the Company and the Subsidiary Guarantors 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. WITH CONSENT OF HOLDERS OF NOTES. Except as provided below in this Section 9.02, the Company, the Subsidiary Guarantors and the Trustee may amend or supplement this Indenture or the Notes with the consent of the Holders of at least a majority in aggregate principal amount of the Notes then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, 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 47 of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including consents obtained in connection with a purchase of, or tender offer or exchange offer for 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 9.06 hereof, the Trustee shall join with the Company and the Subsidiary Guarantors in the execution of such amended or supplemental Indenture unless such amended or supplemental Indenture 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. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in aggregate principal amount of the Notes then outstanding may waive compliance in a particular instance by the Company and the Subsidiary Guarantors with any provision of this Indenture or the Notes. However, without the consent of each Holder affected, an amendment or waiver may not (with respect to any Notes held by a non-consenting Holder): reduce the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver; reduce the principal of or change the fixed maturity of any Note or alter or waive any of the provisions with respect to the redemption of the Notes (except as provided below with respect to Sections 3.09, 4.10 and 4.15 hereof); reduce the rate of or change the time for payment of interest, including default interest, on any Note; waive a Default or Event of Default in the payment of principal of or premium, if any, or interest on the Notes (except a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the then outstanding Notes and a waiver of the payment default that resulted from such acceleration); make any Note payable in money other than that stated in the Notes; make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders of Notes to receive payments of principal of or premium, if any, or interest on the Notes; waive a redemption payment with respect to any Note (other than a payment required by Section 4.10 or 4.15 hereof); alter the ranking of the Notes relative to other Indebtedness of the Company in a manner adverse to the Holders; or make any change in the foregoing amendment and waiver provisions. In addition, without the consent of Holders of not less than 66-2/3% in aggregate principal amount of the Notes then outstanding, no such amendment, supplement or waiver may amend, change or modify the obligation of the Company to make and consummate a Change of Control Offer in the event of a Change of Control or make and consummate an Asset Sale Offer with respect to any Asset Sale or modify any of the provisions or definitions with respect thereto. 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 shall be sufficient if such consent approves the substance thereof. 48 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. 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. 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. 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 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. 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 its Board of Directors approves it. In executing any amended or supplemental Indenture, the Trustee shall be entitled to receive and (subject to Section 7.01 hereof) shall be fully protected in relying upon, an Officers' Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental Indenture is authorized or permitted by this Indenture. SUBSIDIARY GUARANTEES SUBSIDIARY GUARANTEES. The Subsidiary Guarantors and each Subsidiary of the Company that in accordance with Section 10.02 hereof is hereafter required to guarantee the obligations of the Company under the Notes and this Indenture hereby jointly and severally and unconditionally guarantees, on a senior basis (each such guarantee being a "Subsidiary Guarantee"), to each Holder of a Note authenticated and delivered by the Trustee irrespective of the validity or enforceability of this Indenture, the Notes or the obligations of the Company under this Indenture or the Notes, that: (i) the principal of, premium, if any, and interest on the Notes shall be paid in full when due, whether at the stated maturity or interest payment or mandatory redemption date, by acceleration, call for redemption or otherwise, and interest on the overdue principal and interest, if any, of the Notes and all other obligations of the Company to the Holders or the Trustee under this Indenture or the Notes shall be promptly paid in full or performed, all in accordance with the terms of this Indenture and the Notes; and (ii) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, they shall be paid in full when due or performed in accordance with the terms of the extension or renewal, whether at maturity, by acceleration or otherwise. Failing 49 payment when due of any amount so guaranteed for whatever reason, each Subsidiary Guarantor shall be obligated to pay the same whether or not such failure to pay has become an Event of Default that could cause acceleration pursuant to Section 6.02 hereof. Each Subsidiary Guarantor agrees that this is a guarantee of payment not a guarantee of collection. Each Subsidiary Guarantor hereby agrees that its obligations with regard to its Subsidiary Guarantee shall be unconditional, irrespective of the validity or enforceability of the Notes or the obligations of the Company under this Indenture, the absence of any action to enforce the same, the recovery of any judgment against the Company or any other obligor with respect to this Indenture, the Notes or the obligations of the Company under this Indenture or the Notes, any action to enforce the same or any other circumstances (other than complete performance) that might otherwise constitute a legal or equitable discharge or defense of a Subsidiary Guarantor. Each Subsidiary Guarantor further, to the extent permitted by law, waives and relinquishes all claims, rights and remedies accorded by applicable law to guarantors and agrees not to assert or take advantage of any such claims, rights or remedies, including but not limited to: (i) any right to require the Trustee, the Holders or the Company (each, a "Benefitted Party") to proceed against the Company or any other Person or to proceed against or exhaust any security held by a Benefitted Party at any time or to pursue any other remedy in any Benefitted Party's power before proceeding against such Subsidiary Guarantor; (ii) the defense of the statute of limitations in any action hereunder or in any action for the collection of any Indebtedness or the performance of any obligation hereby guaranteed; (iii) any defense that may arise by reason of the incapacity, lack of authority, death or disability of any other Person or the failure of a Benefitted Party to file or enforce a claim against the estate (in administration, bankruptcy or any other proceeding) of any other Person; (iv) demand, protest and notice of any kind including but not limited to notice of the existence, creation or incurring of any new or additional Indebtedness or obligation or of any action or non-action on the part of such Subsidiary Guarantor, the Company, any Benefitted Party, any creditor of such Subsidiary Guarantor, the Company or on the part of any other Person whomsoever in connection with any Indebtedness or Obligations hereby guaranteed; (v) any defense based upon an election of remedies by a Benefitted Party, including but not limited to an election to proceed against such Subsidiary Guarantor for reimbursement; (vi) any defense based upon any statute or rule of law that provides that the obligation of a surety must be neither larger in amount nor in other respects more burdensome than that of the principal; (vii) any defense arising because of a Benefitted Party's election, in any proceeding instituted under any Bankruptcy Law, of the application of Section 1111(b)(2) under the Bankruptcy Law; (viii) any defense based on any borrowing or grant of a security interest under Section 364 under the Bankruptcy Law; or (ix) any right to require a proceeding first against the Company, protest, notice and all demands whatsoever. Each Subsidiary Guarantor hereby covenants that its Subsidiary Guarantee will not be discharged except in accordance with Section 10.05 or by complete performance of all of the obligations contained in its Subsidiary Guarantee, the Notes and this Indenture. If any Holder or the Trustee is required by any court or otherwise to return to either the Company or any Subsidiary Guarantor, or any custodian, trustee, or similar official acting in relation to either the Company or such Subsidiary Guarantor, any amount paid by the Company or such Subsidiary Guarantor to the Trustee or such Holder, the applicable Subsidiary Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Subsidiary Guarantor agrees that it will not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Subsidiary Guarantor further agrees that, as between such Subsidiary Guarantor, on the one hand, and the Holders and the Trustee, on the other hand, (i) the maturity of the obligations guaranteed hereby may be accelerated as provided in Section 6.02 hereof for the purposes of this Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration as to the Company or any other obligor on the Notes of the obligations guaranteed hereby and (ii) in the event of any declaration of acceleration of those obligations as provided in Section 6.02 hereof, those obligations (whether or not due and payable) will forthwith become due and payable by such Subsidiary Guarantor for the purpose of this Subsidiary Guarantee. ADDITIONAL SUBSIDIARY GUARANTEES. If, after the Issue Date, (i) the Company or any of its Restricted Subsidiaries shall (A) transfer or cause to be transferred, any assets, businesses, divisions, real property or equipment having a fair market or book value in excess of $1 million to any Restricted Subsidiary that is not a Subsidiary Guarantor or (B) make any Investment having an aggregate fair market or book value in excess of $1 million in any Restricted Subsidiary that is 50 not a Subsidiary Guarantor, or (ii) any Restricted Subsidiary that is not a Subsidiary Guarantor (A) shall provide a guarantee under the Senior Credit Facility or (B) shall own any assets or properties having an aggregate fair market or book value in excess of $1 million, then the Company shall cause such Restricted Subsidiary (other than any Exempt Foreign Subsidiary) to execute and deliver a supplemental indenture to this Indenture, substantially in the form of Exhibit D hereto, agreeing to be bound by its terms applicable to a Subsidiary Guarantor and providing for a Subsidiary Guarantee of the Notes by such Restricted Subsidiary, in accordance with the terms of this Indenture. The Company shall not permit any of its Restricted Subsidiaries, other than a Subsidiary Guarantor, directly or indirectly, to (i) incur, guarantee or secure through the granting of Liens the payment of any Indebtedness of the Company or (ii) pledge any intercompany notes representing obligations of any of its Restricted Subsidiaries to secure the payment of any Indebtedness of the Company, in each case, unless the Company shall cause such Restricted Subsidiary to execute a supplemental indenture to this Indenture, substantially in the form of Exhibit D hereto, agreeing to be bound by its terms applicable to a Subsidiary Guarantor and providing for a Subsidiary Guarantee of the Notes by such Subsidiary Guarantor, in accordance with the terms of this Indenture. Further, if after the Issue Date, the Company shall revoke the designation of any Exempt Foreign Subsidiary, then the Company shall cause such subsidiary to execute a Subsidiary Guarantee and deliver an Opinion of Counsel in accordance with the terms of this Indenture. LIMITATION OF SUBSIDIARY GUARANTORS' LIABILITY. Each Subsidiary Guarantor and by its acceptance hereof, each beneficiary hereof, hereby confirm that it is its intention that the Subsidiary Guarantee by such Subsidiary Guarantor not constitute a fraudulent transfer or conveyance for purposes of the Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any of the Subsidiary Guarantees. To effectuate the foregoing intention, each such Person hereby irrevocably agrees that the obligations of such Subsidiary Guarantor under its Subsidiary Guarantee under this Article 10 shall be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Subsidiary Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Subsidiary Guarantor in respect of the obligations of such other Subsidiary Guarantor under its Subsidiary Guarantee or pursuant to its contribution obligations under this Indenture, result in the obligations of such Subsidiary Guarantor under the Subsidiary Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal or state law. For purposes of such limitations and the applicable fraudulent conveyance laws, any indebtedness of a Subsidiary Guarantor incurred from time to time pursuant to the Senior Credit Facility and secured by a perfected Lien on the assets of such Subsidiary Guarantor (assuming, for purposes of such determination, that the incurrence of any such indebtedness and the granting of any such security interest did not violate any such fraudulent conveyance laws) shall be deemed, to the extent of the value of the assets subject to such Lien, to have been incurred prior to the incurrence by such Subsidiary Guarantor of liability under its Subsidiary Guarantee. Each beneficiary under the Subsidiary Guarantees, by accepting the benefits hereof, confirms its intention that, in the event of a bankruptcy, reorganization or other similar proceeding of the Company or any Subsidiary Guarantor in which concurrent claims are made upon such Subsidiary Guarantor hereunder, to the extent such claims will not be fully satisfied, each such claimant with a valid claim against the Company shall be entitled to a ratable share of all payments by such Subsidiary Guarantor in respect of such concurrent claims. SUBSIDIARY GUARANTORS MAY CONSOLIDATE, ETC., ON CERTAIN TERMS. No Subsidiary Guarantor may consolidate with or merge with or into (whether or not such Subsidiary Guarantor is the surviving Person), another Person (other than the Company or another Subsidiary Guarantor), whether or not affiliated with such Subsidiary Guarantor, unless (i) subject to the provisions of the following paragraph and Section 10.05 hereof, the Person formed by or surviving any such consolidation or merger (if other than such Subsidiary Guarantor) shall execute and deliver a supplemental indenture to this Indenture agreeing to be bound by its terms applicable to a Subsidiary Guarantor and providing for a Subsidiary Guarantee of the Notes by such Person, in accordance with the terms of this Indenture; (ii) immediately after giving effect to such transaction, no Default or Event of Default exists; (iii) such Subsidiary Guarantor, or any Person formed by or surviving any such consolidation or merger, would have Consolidated Net Worth (immediately after giving effect to 51 such transaction), equal to or greater than the Consolidated Net Worth of such Subsidiary Guarantor immediately preceding the transaction; (iv) the Company would be permitted by virtue of the Company's pro forma Fixed Charge Coverage Ratio, immediately after giving effect to such transaction, to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in Section 4.09(a) hereof; and (v) such transaction does not violate any of the covenants contained in Articles 4 and 5 hereof.. Notwithstanding the foregoing, (i) a Subsidiary Guarantor may consolidate with or merge with or into the Company, provided that the surviving corporation (if other than the Company) shall expressly assume by supplemental indenture complying with the requirements of this Indenture, the due and punctual payment of the principal of, premium, if any, and interest on all of the Notes, and the due and punctual performance and observance of all the covenants and conditions of this Indenture to be performed by the Company; and (ii) a Subsidiary Guarantor may consolidate with or merge with or into any other Subsidiary Guarantor. RELEASES OF SUBSIDIARY GUARANTORS. In the event of (i) the designation of any Subsidiary Guarantor as an Unrestricted Subsidiary or (ii) a sale or other disposition of all of the Capital Stock or all or substantially all of the properties or assets of any Subsidiary Guarantor to a third party or an Unrestricted Subsidiary, by way of merger, consolidation or otherwise, in any case, in a transaction or manner that does not violate any of the covenants or other provision of this Indenture, then such Subsidiary Guarantor will be released from and relieved of any obligations under this Indenture and its Subsidiary Guarantee, provided that any Net Proceeds of such sale or other disposition are applied in accordance with Section 4.10 hereof and provided, further, however, that any such termination shall occur only to the extent that all obligations of such Subsidiary Guarantor under all of its guarantees of, and under all of its pledges of assets or other security interests that secure, any other Indebtedness of the Company or its Restricted Subsidiaries shall also terminate upon such release, sale or disposition. "TRUSTEE" TO INCLUDE PAYING AGENT. In case at any time any Paying Agent other than the Trustee shall have been appointed by the Company and be then acting hereunder, the term "Trustee" as used in this Article 10 shall in such case (unless the context shall otherwise require) be construed as extending to and including such Paying Agent within its meaning as fully and for all intents and purposes as if such Paying Agent were named in this Article 10 in place of the Trustee. CONTRIBUTION. In order to provide for just and equitable contribution among the Subsidiary Guarantors, the Subsidiary Guarantors agree, inter se, that in the event any payment or distribution is made by any Subsidiary Guarantor (a "Funding Guarantor") under a Subsidiary Guarantee, such Funding Guarantor shall be entitled to a contribution from all other Subsidiary Guarantors in a pro rata amount based on the Adjusted Net Assets (as defined below) of each Subsidiary Guarantor (including the Funding Guarantor) for all payments, damages and expenses incurred by that Funding Guarantor in discharging the Company's obligations with respect to the Notes or any other Subsidiary Guarantor's obligations with respect to such Subsidiary Guarantee. "Adjusted Net Assets" of such Subsidiary Guarantor at any date shall mean the lesser of the amount by which (x) the fair value of the property of such Subsidiary Guarantor exceeds the total amount of liabilities, including, without limitation, contingent liabilities, but excluding liabilities under the Subsidiary Guarantee of such Subsidiary Guarantor at such date and (y) the present fair salable value of the assets of such Subsidiary Guarantor at such date exceeds the amount that will be required to pay the probable liability of such Subsidiary Guarantor on its debts (after giving effect to all other fixed and contingent liabilities incurred or assumed on such date and after giving effect to any collection from any subsidiary of such Subsidiary Guarantor in respect of the obligations of such subsidiary under the Subsidiary Guarantees), excluding debt in respect of the Subsidiary Guarantees, as they become absolute and matured. EXECUTION OF NOTATIONS OF SUBSIDIARY GUARANTEES. To evidence its guarantee to each Holder of Notes, each of the Subsidiary Guarantors hereby agree to execute a notation of its Subsidiary Guarantee in substantially the form set forth in Exhibit A or Exhibit B, as 52 applicable, on each Note ordered to be authenticated and delivered by the Trustee.

Without the consent of any Holder of a Note, the Indenture or the Notes may be amended or supplemented to cure any ambiguity, defect or inconsistency, to provide for uncertificated Notes in addition to or in place of certificated Notes, to provide for the assumption of the Company's obligations to Holders of the Notes in case of a merger or consolidation, to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights under the Indenture of any such Holder, to secure the Notes, to add or release any Subsidiary Guarantor pursuant to the terms of the Indenture or to comply with the requirements of the Commission in order to effect or maintain the qualification of the Indenture under the TIA. 12. Defaults and Remedies. Events of Default include: (i) default for 30 days in the payment when due of interest on, or Liquidated Damages with respect to, the Notes; (ii) default in payment when due of principal of or premium, if any, on the Notes when the same becomes due and payable at stated maturity, upon redemption (including in connection with an offer to purchase) or otherwise, (iii) failure by the Company to comply with Section 4.10, 4.15 or 5.01 of the Indenture; (iv) failure by the Company for 45 days after notice to the Company by the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding to comply A-4 with any of its other agreements in the Indenture or the Notes; (v) default under certain other agreements relating to Indebtedness of the Company or any of its Restricted Subsidiaries, which default (A) is caused by a failure to pay principal of or premium, if any, or interest on such Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of such default (a "Payment Default") or (B) results in the acceleration of such Indebtedness prior to its express maturity and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $7.5 million or more; (vi) certain final judgments for the payment of money that remain undischarged for a period of 60 days; (vii) any Subsidiary Guarantee shall for any reason cease to be, or be asserted by the Company or any Subsidiary Guarantor, as applicable, not to be, in full force and effect (except pursuant to the release of any Subsidiary Guarantee in accordance with the Indenture); and (viii) certain events of bankruptcy or insolvency with respect to the Company or any of its Restricted Subsidiaries that constitutes a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary. If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately. Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency with respect to the Company, any Restricted Subsidiary that constitutes a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary, all outstanding Notes will become due and payable without further action or notice. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal or interest) if it determines that withholding notice is in their interest. The Holders of a majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in the payment of interest on, or the principal of, the Notes. The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Company is required upon becoming aware of any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default. 13. Trustee Dealings with the Company. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not the Trustee. 14. No Recourse Against Others. No past, present or future director, officer, employee, incorporation, stockholder of the Company or any Subsidiary Guarantor, as such, shall have any liability for any obligations of the Company or such Subsidiary Guarantor under the Notes, the Indenture or the Subsidiary Guarantees, as the case may be, or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Notes and the Subsidiary Guarantees. 15. Authentication. This Note shall not be valid until authenticated by the manual signature of the Trustee. 16. Abbreviations. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). 17. Additional Rights of Holders of Transfer Restricted Securities. In addition to the rights provided to Holders of Notes under the Indenture, Holders of Transferred Restricted Securities shall have all the rights set forth in the Registration Rights Agreement dated as of March 11, 1998, among the Company, the Subsidiary Guarantors and Jefferies & Company, Inc. (the "Registration Rights Agreement"). 18. CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon. A-5 The Company shall furnish to any Holder upon written request and without charge a copy of the Indenture and/or the Registration Rights Agreement.

The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal or interest) if it determines that withholding notice is in their interest. The Holders of a majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in the payment of interest on, or the principal of, the Notes. The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Company is required upon becoming aware of any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default. 13. Trustee Dealings with the Company. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not the Trustee. 14. No Recourse Against Others. No past, present or future director, officer, employee, incorporation, stockholder of the Company or any Subsidiary Guarantor, as such, shall have any liability for any obligations of the Company or such Subsidiary Guarantor under the Notes, the Indenture or the Subsidiary Guarantees, as the case may be, or for any claim based on, in respect of, or by reason of, such obligations or their creation.

Authentication. This Note shall not be valid until authenticated by the manual signature of the Trustee. 16. Abbreviations. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). 17. CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon. The Company shall furnish to any Holder upon written request and without charge a copy of the Indenture.
