At such time as all beneficial interests in a particular Global Note have been exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or cancelled in whole and not in part, each such Global Note shall be returned to or retained and cancelled 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 or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the principal amount of Notes represented by such Global Note shall be reduced accordingly and 45 an endorsement may be made on such Global Note by the Trustee or by the Depositary 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 may be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such increase. (i) General Provisions Relating to Transfers and Exchanges. (1) To permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Global Notes and Definitive Notes upon receipt of an Authentication Order. (2) No service charge shall be made to a holder of a beneficial interest in a Global Note or to a Holder of a Definitive Note 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 2.10, 3.7, 4.14 and 10.1 hereof). (3) 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. (4) All Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes shall be the valid obligations of the Company, evidencing the same Indebtedness, and entitled to the same benefits under this Indenture, as the Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange. (5) The Company shall not be required (A) to issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business 15 days before the day of any selection of Notes for redemption under Section 3.3 hereof and ending at the close of business on the day of selection, (B) 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 (C) to register the transfer of or to exchange a Note between a Record Date and the next succeeding Interest Payment Date. (6) Prior to due presentment for the registration of a transfer of any Note, the Trustee, any Agent and the Company may deem and treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and interest on such Notes and for all other purposes, and none of the Trustee, any Agent or the Company shall be affected by notice to the contrary. 46 (7) The Trustee shall authenticate Global Notes and Definitive Notes in accordance with the provisions of Section 2.2 hereof.

The Registrar shall not be responsible for confirming the truth or accuracy of representations made in any such certifications or certificates. SECTION 2.7. REPLACEMENT NOTES If any mutilated Note is surrendered to the Trustee or the Company and the Trustee and the Company receive evidence (which evidence may be from the Trustee) to their satisfaction of the destruction, loss or theft of any Note, the Company shall issue and the Trustee, upon receipt of an Authentication Order, shall authenticate a replacement Note if the Trustee's reasonable 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. SECTION 2.8. OUTSTANDING NOTES The Notes outstanding at any time are all the Notes authenticated by the Trustee (including any Note represented by a Global Note) except for those cancelled by it or at its direction, 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 2.9 hereof, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note. If a Note is replaced pursuant to Section 2.7 hereof, such Note, together with the Guarantee of that particular Note endorsed thereon, 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 4.1 hereof, it ceases to be outstanding and interest on it ceases to accrue. If the Paying Agent (other than the Company, a Subsidiary or an Affiliate of any thereof) holds, on a redemption date or the maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes shall be deemed to be no longer outstanding and shall cease to accrue interest. 47 SECTION 2.9. TREASURY NOTES In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company, or by any Affiliate of the Company, shall be considered as though not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes that a Trust Officer of the Trustee actually knows are so owned shall be so disregarded. SECTION 2.10. TEMPORARY NOTES Until certificates representing Notes are ready for delivery, the Company may prepare, and the Trustee, upon receipt of an Authentication Order, shall authenticate, temporary Notes. Temporary Notes shall be substantially in the form of 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 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. SECTION 2.11. CANCELLATION The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee, or, at the direction of the Trustee, the Registrar or the Paying Agent (other than the Company or an Affiliate of the Company), and no one else, shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and shall dispose of cancelled Notes in accordance with its procedures for the disposition of cancelled securities in effect as of the date of such disposition (subject to the record retention requirement of the Exchange Act). Certification of the disposition of all cancelled Notes shall be delivered to the Company, unless the Company directs the Trustee to deliver cancelled Notes to the Company. The Company may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation. SECTION 2.12. DEFAULTED INTEREST Any interest on any Note which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date, plus, to the extent lawful, any interest payable on the defaulted interest at the rate and in the manner provided in Section 4.1 hereof and in the Note (herein called "Defaulted Interest"), shall forthwith cease to be payable to the registered Holder on the relevant Record Date, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause (1) or (2) below: 48 (1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Notes are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee and the Paying Agent in writing of the amount of Defaulted Interest proposed to be paid on each Note and the date of the proposed payment, and at the same time the Company shall deposit with the Paying Agent an amount of cash equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements reasonably satisfactory to the Paying Agent for such deposit prior to the date of the proposed payment, such cash when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as provided in this clause (1). Thereupon the Paying Agent shall fix a "Special Record Date" for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Paying Agent of the notice of the proposed payment. The Paying Agent shall promptly notify the Company and the Trustee of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder at its address as it appears in the Note register maintained by the Registrar not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the persons in whose names the Notes (or their respective predecessor Notes) are registered on such Special Record Date and shall no longer be payable pursuant to the following clause (2). (2) The Company may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee and the Paying Agent of the proposed payment pursuant to this clause, such manner shall be deemed practicable by the Trustee and the Paying Agent. Subject to the foregoing provisions of this Section, each Note delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Note. SECTION 2.13. 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 49 on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee of any change in the "CUSIP" numbers. SECTION 2.14. ISSUANCE OF ADDITIONAL NOTES The company may, subject to Section 4.11 hereof and applicable law, issue Additional Notes under this Indenture. The Notes issued on the Issue Date and any additional Notes subsequently issued shall be treated as a single class for all purposes under this Indenture. ARTICLE III REDEMPTION SECTION 3.1. OPTIONAL REDEMPTION (a) Except as set forth in clause (b) of this Section 3.1, the Company shall not have the option to redeem the Notes pursuant to this Section 3.1 prior to December 15, 2005.

(c) Any redemption pursuant to this Section 3.1 shall be made pursuant to the provisions of Sections 3.2 through 3.7 hereof. SECTION 3.2. NOTICES TO TRUSTEE If the Company elects to redeem Notes pursuant to Section 5 of the Notes, it shall notify the Trustee and the Paying Agent in writing of the Redemption Date and the principal amount of Notes to be redeemed and whether it wants the Paying Agent to give notice of redemption to the Holders. If the Company elects to reduce the principal amount of Notes to be redeemed pursuant to Section 5 of the Notes by crediting against any such redemption Notes it has not previously delivered to the Trustee and the Paying Agent for cancellation, it shall so notify the Trustee, in the form of an Officers' Certificate, and the Paying Agent of the amount of the reduction and deliver such Notes with such notice. The Company shall give each notice to the Trustee and the Paying Agent provided for in this Section 3.2 at least 15 days before the date on which the notice of redemption is to be given (unless a shorter notice shall be satisfactory to the Trustee and the Paying Agent). Any such notice may be cancelled at any time prior to notice of such redemption being mailed to any Holder and shall thereby be void and of no effect. SECTION 3.3. 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 or portions thereof 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. The Trustee shall make the selection from the Notes outstanding and not previously called for redemption and shall promptly notify the Company and the Paying Agent 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 in denominations of $1,000 may be redeemed only in whole. The Trustee may select for redemption portions (equal to $1,000 or any integral multiple thereof) of the principal of Notes that have denominations larger than $1,000. Provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption. 51 SECTION 3.4. NOTICE OF REDEMPTION At least 30 days, but not more than 60 days, prior to the Redemption Date, the Company shall mail a notice of redemption by first class mail, postage prepaid, to the Trustee, the Paying Agent and each Holder whose Notes are to be redeemed. At the Company's request delivered at least 15 days prior to the date on which such notice is to be given (unless a shorter period shall be acceptable to the Paying Agent), the Paying Agent shall give the notice of redemption in the Company's name and at the Company's expense. Each notice for redemption shall identify the Notes to be redeemed and shall state: (1) the Redemption Date; (2) the Redemption Price, including accrued and unpaid interest and Liquidated Damages, if any, to be paid upon such redemption; (3) the name and address of the Paying Agent; (4) that Notes called for redemption must be surrendered to the Paying Agent at the address specified in such notice to collect the Redemption Price; (5) that, unless (a) the Company defaults in its obligation to deposit with the Paying Agent cash which through the scheduled payment of principal and interest (and Liquidated Damages, if any) in respect thereof in accordance with their terms shall provide the amount to fund the Redemption Price in accordance with Section 3.6 hereof or (b) such redemption payment is prohibited, interest (and Liquidated Damages, if any) on Notes called for redemption ceases to accrue on and after the Redemption Date and the only remaining right of the Holders of such Notes is to receive payment of the Redemption Price, including accrued and unpaid interest (and Liquidated Damages, if any) to the Redemption Date, upon surrender to the Paying Agent of the Notes called for redemption and to be redeemed; (6) if any Note is being redeemed in part, the portion of the principal amount, equal to $1,000 or any integral multiple thereof, of such Note to be redeemed and that, on and after the Redemption Date, and upon surrender of such Note, a new Note or Notes in aggregate principal amount equal to the unredeemed portion thereof shall be issued; (7) if less than all the Notes are to be redeemed, the identification of the particular Notes (or portion thereof) to be redeemed, as well as the aggregate principal amount of such Notes to be redeemed and the aggregate principal amount of Notes to be outstanding after such partial redemption; (8) the CUSIP number of the Notes to be redeemed; and (9) that the notice is being sent pursuant to this Section 3.4 and pursuant to the optional redemption provisions of Section 5 of the Notes. 52 SECTION 3.5. EFFECT OF NOTICE OF REDEMPTION Once notice of redemption is mailed in accordance with Section 3.4 hereof, Notes called for redemption become due and payable on the Redemption Date and at the Redemption Price, including accrued and unpaid interest (and Liquidated Damages, if any) to the Redemption Date. Upon surrender to the Trustee or Paying Agent, such Notes called for redemption shall be paid at the Redemption Price, including interest and Liquidated Damages, if any, accrued and unpaid to the Redemption Date; provided, that if the Redemption Date is on or after an interest Record Date on which the Holders of record have a right to receive the corresponding interest due, and Liquidated Damages, if any, and is on or before the associated Interest Payment Date, any accrued and unpaid interest and Liquidated Damages, if any, due on such Interest Payment Date shall be paid to the Person in whose name a Note is registered at the close of business on such Record Date on the corresponding Interest Payment Date; and provided, further, that if a Redemption Date is a Legal Holiday, payment shall be made on the next succeeding Business Day and no interest shall accrue for the period from such Redemption Date to such succeeding Business Day. SECTION 3.6. DEPOSIT OF REDEMPTION PRICE On or prior to the Redemption Date, the Company shall deposit with the Paying Agent (other than the Company or an Affiliate of the Company) cash sufficient to pay the Redemption Price of all Notes to be redeemed on such Redemption Date (other than Notes or portions thereof called for redemption on that date that have been delivered by the Company to the Trustee for cancellation). The Paying Agent shall promptly return to the Company any cash so deposited which is not required for that purpose upon the written request of the Company. If the Company complies with the preceding paragraph and payment of the Notes called for redemption is not prohibited for any reason, interest (and Liquidated Damages, if any) on the Notes to be redeemed shall cease to accrue on the applicable Redemption Date, whether or not such Notes are presented for payment. Notwithstanding anything herein to the contrary, if any Note surrendered for redemption in the manner provided in the Notes shall not be so paid upon surrender for redemption because of the failure of the Company to comply with the preceding paragraph, interest shall (and Liquidated Damages, if any) continue to accrue and be paid from the Redemption Date until such payment is made on the unpaid principal, and, to the extent lawful, on any interest not paid on such unpaid principal, in each case at the rate and in the manner provided in Section 4.1 hereof and the Note. SECTION 3.7. NOTES REDEEMED IN PART Upon surrender of a Note that is to be redeemed in part, the Company shall execute, and the Trustee shall authenticate and deliver to the Holder, without service charge to the Holder, a new Note or Notes equal in principal amount to the unredeemed portion of the Note surrendered. 53 SECTION 3.8. NO MANDATORY REDEMPTION The Company shall not be required to make mandatory redemption payments with respect to the Notes. The Notes shall not have the benefit of any sinking fund. ARTICLE IV COVENANTS SECTION 4.1. PAYMENT OF NOTES The Company shall pay the principal of and interest (and Liquidated Damages, if any) on the Notes on the dates and in the manner provided herein and in the Notes. An installment of principal of or interest (or Liquidated Damages, if any) on the Notes shall be considered paid on the date it is due if the Trustee or Paying Agent (other than the Company or an Affiliate of the Company) holds for the benefit of the Holders (on or before 11:00 a.m. New York City time to the extent necessary to provide the funds to the Depositary in accordance with the Depositary's procedures) on that date cash deposited and designated for and sufficient to pay the installment. The Company shall pay interest on overdue principal and on overdue installments of interest (and Liquidated Damages, if any) at the rate specified in the Notes compounded semi- annually, to the extent lawful. SECTION 4.2. MAINTENANCE OF OFFICE OR AGENCY The Company and the Guarantors shall maintain in the Borough of Manhattan, The City of New York, an office or agency where Notes may be presented or surrendered for payment, where Notes may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Company and the Guarantors in respect of the Notes and this Indenture may be served. The Company and the Guarantors shall give prompt written notice to the Trustee and the Paying Agent of the location, and any change in the location, of such office or agency. If at any time the Company and the Guarantors shall fail to maintain any such required office or agency or shall fail to furnish the Trustee and the Paying Agent with the address thereof, such presentations, surrenders, notices and demands may be made or served at the address of the Trustee set forth in Section 12.2 hereof. The Company and the Guarantors may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company and the Guarantors of their obligation to maintain an office or agency in the Borough of Manhattan, The City of New York, for such purposes. The Company and the Guarantors shall give prompt written notice to 54 the Trustee and the Paying Agent of any such designation or rescission and of any change in the location of any such other office or agency. The Company hereby initially designates the Corporate Trust Office of the Trustee as such office. SECTION 4.3. LIMITATION ON RESTRICTED PAYMENTS The Company and the Guarantors shall not, and neither the Company nor the Guarantors shall permit any of their respective Subsidiaries to, directly or indirectly, make any Restricted Payment if, after giving effect to such Restricted Payment on a pro forma basis: (1) a Default or an Event of Default shall have occurred and be continuing; (2) the Company is not permitted to incur at least $1.00 of additional Indebtedness pursuant to the Debt Incurrence Ratio; or (3) the aggregate amount of all Restricted Payments made by the Company and its Subsidiaries, including after giving effect to such proposed Restricted Payment, on and after the Issue Date, would exceed, without duplication, the sum of: (a) 50% of the Company's aggregate Consolidated Net Income for the period (taken as one accounting period), commencing on the first day of the first full fiscal quarter commencing after the Issue Date, to and including the last day of the fiscal quarter ended immediately prior to the date of each such calculation for which the Company's consolidated financial statements are required to be delivered to the Trustee or, if sooner, filed with the SEC (or, in the event Consolidated Net Income for such period is a deficit, then minus 100% of such deficit); plus (b) the aggregate Net Cash Proceeds received by the Company from the issuance or sale of its Qualified Capital Stock (other than (i) to one of the Company's Subsidiaries and (ii) to the extent applied in connection with a Qualified Exchange or, to avoid duplication, otherwise given credit for in any provision of paragraph (c) below), after the Issue Date; plus (c) except in each case, in order to avoid duplication, to the extent any such payment or proceeds have been included in the calculation of Consolidated Net Income, an amount equal to the net reduction in Investments (other than returns of or from Permitted Investments) in any Person resulting from cash distributions on or cash repayments of any Investments, including payments of interest on Indebtedness, dividends, repayments of loans or advances, or other distributions or other transfers of assets, in each case to the Company or any Subsidiary or from the Net Cash Proceeds from the sale of any such Investment or from redesignations of Unrestricted Subsidiaries as Subsidiaries (valued in each case as provided in the definition of "Investments"), 55 not to exceed, in each case, the amount of Investments previously made by the Company or any Subsidiary in such Person, including, if applicable, such Unrestricted Subsidiary, less the cost of disposition. The foregoing clauses (2) and (3) of the immediately preceding paragraph, however, shall not prohibit: (u) repurchases of Capital Stock from the Company's employees or directors (or their heirs or estates) or employees or directors (or their heirs or estates) of its Subsidiaries upon the death, disability or termination of employment in an aggregate amount to all employees or directors (or their heirs or estates) not to exceed in the aggregate $1,000,000 per calendar year; (v) Restricted Payments in an aggregate amount not to exceed $5,000,000, and the provisions of the immediately preceding paragraph shall not prohibit: (w) any dividend, distribution or other payments by any of the Company's Subsidiaries on its Equity Interests that is paid pro rata to all holders of such Equity Interests; (x) a Qualified Exchange; (y) the payment of any dividend on Qualified Capital Stock within 60 days after the date of its declaration if such dividend could have been made on the date of such declaration in compliance with the foregoing provisions; or (z) in the event of a Change of Control that also constitutes a "Change of Control" as defined in the Convertible Note, the prepayment or redemption of the Convertible Note in accordance with Section 4 thereof (Mandatory Prepayment/Redemption) as in effect on the Issue Date; provided, that no such prepayment or redemption may be made under this clause (z) until the Company has made a Change of Control Offer in accordance with Section 10.1 and any Notes tendered pursuant thereto have been purchased in accordance therewith on or prior to the Change of Control Purchase Date; and provided further, that the Company shall include in the Change of Control Offer notice delivered to Holders a statement that the Company will prepay or redeem the Convertible Note upon the completion of the Change of Control Offer in accordance with this clause (z). The full amount of any Restricted Payment made pursuant to the foregoing clauses (u), (w) (to avoid duplication, exclusive of amounts that reduced Consolidated Net Income), (y) and (z) (but not pursuant to clause (v) or (x)) of the immediately preceding sentence, however, will be counted as Restricted Payments made for purposes of the calculation of the aggregate amount 56 of Restricted Payments available to be made referred to in clause (3) of the first paragraph of this Section 4.3. For purposes of this Section 4.3, the amount of any Restricted Payment made or returned, if other than in cash, shall be the fair market value thereof, as determined in the good faith reasonable judgment of the Company's Board of Directors, unless stated otherwise, at the time made or returned, as applicable. Additionally, on the date of each Restricted Payment, the Company shall deliver an Officers' Certificate to the Trustee describing in reasonable detail the nature of such Restricted Payment in excess of $10,000,000 that is not a Restricted Investment, stating the amount of such Restricted Payment, stating in reasonable detail the provisions of this Indenture pursuant to which such Restricted Payment was made and certifying that such Restricted Payment was made in compliance with the terms of this Indenture. SECTION 4.4. CORPORATE AND PARTNERSHIP EXISTENCE Except as otherwise permitted by Article V, Section 4.14 or Section 11.4, the Company and the Guarantors shall do or cause to be done all things necessary to preserve and keep in full force and effect their respective corporate, partnership or other organizational existence, as the case may be, and the corporate, partnership or other organizational existence, as the case may be, of each of their Subsidiaries in accordance with the respective organizational documents of each of them and the material rights (charter and statutory) and material corporate franchises of the Company, the Guarantors and each of their respective Subsidiaries; provided, however, that neither the Company nor any Guarantor shall be required to preserve, with respect to themselves, any right or franchise, and with respect to any of their respective Subsidiaries, any such existence, right or franchise, if (a) the Company shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and (b) the loss thereof is not adverse in any material respect to the Holders. SECTION 4.5. PAYMENT OF TAXES AND OTHER CLAIMS The Company and the Guarantors shall, and each of the Company and the Guarantors shall cause each of their Subsidiaries to, pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (a) all material taxes, assessments and governmental charges (including withholding taxes and any penalties, interest and additions to taxes) levied or imposed upon the Company, any Guarantor or any of their Subsidiaries or any of their respective properties and assets and (b) all material lawful claims, whether for labor, materials, supplies or services, which have become due and payable and which by law have or may become a Lien upon the property and assets of the Company, any Guarantor or any of their Subsidiaries; provided, however, that neither the Company nor any Guarantor shall be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith by appropriate proceedings and for which disputed amounts adequate reserves have been established in accordance with GAAP. 57 SECTION 4.6. MAINTENANCE OF PROPERTIES AND INSURANCE The Company and the Guarantors shall cause all material properties used or useful in the conduct of their business and the business of each of their Subsidiaries to be maintained and kept in good condition, repair and working order (reasonable wear and tear excepted) and supplied with all necessary equipment and shall cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as in their reasonable judgment may be necessary, so that the business carried on in connection therewith may be properly conducted at all times; provided, however, that nothing in this Section 4.6 shall prevent the Company or any Guarantor from discontinuing any operation or maintenance of any of such properties, or disposing of any of them, if such discontinuance or disposal is (a)(i) in the judgment of the Board of Directors of the Company, desirable in the conduct of the business of the Company and (ii) not adverse in any material respect to the Holders or (b) otherwise permitted under Section 4.14. The Company and the Guarantors shall provide, or cause to be provided, for themselves and each of their Subsidiaries, insurance (including appropriate self-insurance) against loss or damage of the kinds that, in the reasonable, good faith opinion of the Board of Directors of the Company, is adequate and appropriate for the conduct of the business of the Company, the Guarantors and such Subsidiaries in a prudent manner, with (except for self- insurance) reputable insurers or with the government of the United States of America or an agency or instrumentality thereof, in such amounts, with such deductibles, and by such methods as shall be customary, in the reasonable, good faith opinion of the Company and adequate and appropriate for the conduct of the business of the Company, the Guarantors and such Subsidiaries in a prudent manner for entities similarly situated in the industry. SECTION 4.7. COMPLIANCE CERTIFICATE; NOTICE OF DEFAULT (a) The Company shall deliver to the Trustee within 120 days after the end of its fiscal year an Officers' Certificate, one of the signers of which shall be the principal executive, principal financial or principal accounting officer of the Company, complying with TIA 314(a)(4) and stating that a review of its activities and the activities of its Subsidiaries, if any, 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 (without regard to notice requirements or grace periods) and further stating, as to each such Officer signing such certificate, whether or not the signer knows of any failure by the Company, any Guarantor or any Subsidiary of the Company to comply with any conditions or covenants in this Indenture and, if such signer does know of such a failure to comply, the certificate shall describe such failure with particularity. The Officers' Certificate shall also notify the Trustee should the relevant fiscal year end on any date other than the current fiscal year end date. (b) The Company shall, so long as any of the Notes are outstanding, deliver to the Trustee, promptly upon becoming aware of any Default or Event of Default, an Officers' 58 Certificate specifying such Default or Event of Default and what action the Company is taking or proposes to take with respect thereto. The Trustee shall not be deemed to have knowledge of any Default, any Event of Default or any such fact unless one of its Trust Officers receives written notice thereof from the Company or any of the Holders. SECTION 4.8. REPORTS Whether or not the Company is subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, the Company shall furnish to the Trustee and deliver or cause to be delivered, to each Holder and to prospective purchasers of Notes identified to the Company by an Initial Purchaser, within 5 days after the Company is or would have been (if it were subject to such reporting obligations) required to file such with the SEC, annual and quarterly financial statements substantially equivalent to financial statements that would have been included in reports filed with the SEC, if the Company were subject to the requirements of Section 13 or 15(d) of the Exchange Act, including, with respect to annual information only, a report thereon by the Company's certified independent public accountants as such would be required in such reports to the SEC, and, in each case, together with a management's discussion and analysis of financial condition and results of operations which would be so required and, unless the SEC will not accept such reports, file with the SEC the annual, quarterly and other reports which the Company is or would have been required to file with the SEC. Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee's receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company's compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers' Certificates). For so long as any Transfer Restricted Notes remain outstanding, the Company shall make available (which shall include filings by EDGAR) to all Holders and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act. SECTION 4.9. LIMITATION ON STATUS AS INVESTMENT COMPANY Neither the Company nor any of its Subsidiaries shall become required to register as an "investment company" (as that term is defined in the Investment Company Act of 1940, as amended), or from otherwise becoming subject to regulation under the Investment Company Act. SECTION 4.10. LIMITATION ON TRANSACTIONS WITH AFFILIATES Neither the Company nor any of its Subsidiaries shall on or after the Issue Date enter into or suffer to exist any contract, agreement, arrangement or transaction with any Affiliate (an "Affiliate Transaction"), or any series of related Affiliate Transactions (other than 59 Exempted Affiliate Transactions), (1) unless it is determined that the terms of such Affiliate Transaction are fair and reasonable to the Company, and no less favorable to the Company than could have been obtained in an arm's length transaction with a non-Affiliate, and (2) if involving consideration to either party in excess of $2,000,000, unless such Affiliate Transaction(s) has been approved by a majority of the members of the Company's Board of Directors that are disinterested in such transaction, if there are any directors who are so disinterested, and (3) if involving consideration to either party in excess of $10,000,000, or $2,000,000 if there are no disinterested directors for such transaction, unless, in addition the Company, prior to the consummation thereof, obtains a written favorable opinion as to the fairness of such transaction to the Company from a financial point of view from an independent investment banking firm of national reputation in the United States or, if pertaining to a matter for which such investment banking firms do not customarily render such opinions, an accounting, appraisal or valuation firm of national reputation in the United States. Within 5 days of any Affiliate Transaction(s) involving consideration to either party of $2,000,000 or more, the Company shall deliver to the Trustee an Officers' Certificate addressed to the Trustee certifying that such Affiliate Transaction (or Transactions) complied with clause (1), (2), and (3), of this Section 4.10, as applicable. SECTION 4.11. LIMITATION ON INCURRENCE OF ADDITIONAL INDEBTEDNESS Except as set forth in this Section 4.11, the Company and the Guarantors shall not, and neither the Company nor the Guarantors shall permit any of their respective Subsidiaries to, directly or indirectly, issue, assume, guarantee, incur, become directly or indirectly liable with respect to (including as a result of an Acquisition), or otherwise become responsible for, contingently or otherwise (individually and collectively, to "incur" or, as appropriate, an "incurrence"), any Indebtedness (including Disqualified Capital Stock and Acquired Indebtedness), other than Permitted Indebtedness. Notwithstanding the foregoing if: (1) no Default or Event of Default shall have occurred and be continuing at the time of, or would occur after giving effect on a pro forma basis to, such incurrence of Indebtedness and (2) on the date of such incurrence (the "Incurrence Date"), the Company's Consolidated Coverage Ratio for the Reference Period immediately preceding the Incurrence Date, after giving effect on a pro forma basis to such incurrence of such Indebtedness and, to the extent set forth in the definition of Consolidated Coverage Ratio, the use of proceeds thereof, would be at least (x) 2.5 to 1.0, if such incurrence occurs prior to January 1, 2004, and (y) 2.75 to 1.0, if the incurrence occurs on or after January 1, 2004 (the "Debt Incurrence Ratio"), 60 then the Company and the Guarantors may incur such Indebtedness (including Disqualified Capital Stock). In addition, the foregoing limitations of the first paragraph of this Section 4.11 will not prohibit: (a) the Company's incurrence or the incurrence by any Guarantor of Purchase Money Indebtedness; provided, that (1) the aggregate amount of such Indebtedness incurred and outstanding at any time pursuant to this paragraph (a) (plus any Refinancing Indebtedness issued to retire, defease, refinance, replace or refund such Indebtedness) shall not exceed $10,000,000; and (2) in each case, such Indebtedness shall not constitute more than 100% of the Company's cost or the cost to such Guarantor (determined in accordance with GAAP), as applicable, of the property so purchased, constructed, improved or leased; (b) if no Event of Default shall have occurred and be continuing, the Company's incurrence or the incurrence by any Guarantor of Indebtedness in an aggregate amount incurred and outstanding at any time pursuant to this paragraph (b) (plus any Refinancing Indebtedness incurred to retire, defease, refinance, replace or refund such Indebtedness) of up to $17,500,000; and (c) the Company's incurrence or the incurrence by any Guarantor of Indebtedness pursuant to the Credit Agreement in an aggregate amount incurred and outstanding at any time pursuant to this paragraph (c) (plus any Refinancing Indebtedness incurred to retire, defease, refinance, replace or refund such Indebtedness) of up to $35,000,000, minus the amount of any such Indebtedness (1) retired with the Net Cash Proceeds from any Asset Sale applied to permanently reduce the outstanding amounts or the commitments with respect to such Indebtedness pursuant to clause (b) of the second paragraph of Section 4.14 or (2) assumed by a transferee in an Asset Sale so long as neither the Company nor such Guarantor continues to be an obligor under such Indebtedness. Indebtedness (including Disqualified Capital Stock) of any Person which is outstanding at the time such Person becomes one of the Company's Subsidiaries (including upon designation of any subsidiary or other Person as a Subsidiary) or is merged with or into or consolidated with the Company or one of the Company's Subsidiaries shall be deemed to have been incurred at the time such Person becomes or is designated one of the Company's Subsidiaries or is merged with or into or consolidated with the Company or one of the Company's Subsidiaries as applicable. 61 Notwithstanding any other provision of this Section 4.11, but only to avoid duplication, a guarantee of the Company's Indebtedness or of the Indebtedness of another Guarantor incurred in accordance with the terms of this Indenture issued at the time such Indebtedness was incurred or if later at the time the guarantor thereof became one of the Company's Subsidiaries will not constitute a separate incurrence, or amount outstanding, of Indebtedness. Upon each incurrence the Company may designate pursuant to which provision of this Section 4.11 such Indebtedness is being incurred and the Company may subdivide an amount of Indebtedness and designate more than one provision pursuant to which such amount of Indebtedness is being incurred and such Indebtedness shall not be deemed to have been incurred or outstanding under any other provision of this Section 4.11, except as stated otherwise in the foregoing provisions. SECTION 4.12. LIMITATIONS ON DIVIDENDS AND OTHER PAYMENT RESTRICTIONS AFFECTING SUBSIDIARIES The Company and the Guarantors shall not, and neither the Company nor the Guarantors shall permit any of their respective Subsidiaries to, directly or indirectly, create, assume or suffer to exist any consensual restriction on the ability of any Subsidiary of the Company to pay dividends or make other distributions to or on behalf of, or to pay any obligation to or on behalf of, or otherwise to transfer assets or property to or on behalf of, or to make or pay loans or advances to or on behalf of, the Company or any of its Subsidiaries, except: (1) restrictions imposed by the Notes or this Indenture or by the Company's other Indebtedness (which may also be guaranteed by the Guarantors); provided, that such restrictions are not materially more restrictive than those imposed by this Indenture and the Notes; (2) restrictions imposed by applicable law; (3) existing restrictions under Existing Indebtedness; (4) restrictions under any Acquired Indebtedness not incurred in violation of this Indenture or any agreement (including any Equity Interest) relating to any property, asset, or business acquired by the Company or any of its Subsidiaries, which restrictions in each case existed at the time of acquisition, were not put in place in connection with or in anticipation of such acquisition and are not applicable to any Person, other than the Person acquired, or to any property, asset or business, other than the property, assets and business so acquired; (5) any restriction imposed by Indebtedness incurred under the Credit Agreement pursuant to clause (c) of Section 4.11; provided, that such restriction or requirement is no more restrictive than that imposed by the Credit Agreement as of the Issue Date; 62 (6) restrictions with respect solely to any of the Company's Subsidiaries imposed pursuant to a binding agreement which has been entered into for the sale or disposition of all of the Equity Interests or assets of such Subsidiary; provided, that such restrictions apply solely to the Equity Interests or assets of such Subsidiary which are being sold; (7) restrictions on transfer contained in Purchase Money Indebtedness incurred pursuant to clause (a) of Section 4.11; provided, that such restrictions relate only to the transfer of the property acquired with the proceeds of such Purchase Money Indebtedness; (8) in connection with and pursuant to permitted Refinancings, replacements of restrictions imposed pursuant to clauses (1), (3), (4) or (7) or this clause (8) of this paragraph that are not materially more restrictive than those being replaced and do not apply to any other Person or assets than those that would have been covered by the restrictions in the Indebtedness so refinanced; and (9) customary provisions in partnership agreements, limited liability company organizational governance documents, joint venture agreements and other similar agreements entered into in the ordinary course of business that restrict the transfer of ownership interests in such partnership, limited liability company, joint venture or similar Person. Notwithstanding the foregoing, (a) customary provisions restricting subletting or assignment of any lease entered into in the ordinary course of business, consistent with industry practice and (b) any asset subject to a Lien which is not prohibited to exist with respect to such asset pursuant to the terms of this Indenture may be subject to customary restrictions on the transfer or disposition thereof pursuant to such Lien. SECTION 4.13. LIMITATIONS ON LAYERING INDEBTEDNESS The Company and the Guarantors shall not, and neither the Company nor the Guarantors shall permit any of their respective Subsidiaries to, directly or indirectly, incur any Indebtedness that is contractually subordinate to any of the Company's other Indebtedness or the other Indebtedness of any Guarantor unless, by its terms, such Indebtedness is made at least as contractually subordinate to the Notes or the Guarantees, as applicable. SECTION 4.14. LIMITATION ON SALES OF ASSETS AND SUBSIDIARY STOCK The Company and the Guarantors shall not, and neither the Company nor the Guarantors shall permit any of their respective Subsidiaries to, in one or a series of related transactions, convey, sell, transfer, assign or otherwise dispose of, directly or indirectly, any of their property, business or assets, including by merger or consolidation (in the case of a Guarantor or one of the Company's Subsidiaries), and including any sale or other transfer or 63 issuance of any Equity Interests of any of the Company's Subsidiaries, whether by the Company or one of its Subsidiaries or through the issuance, sale or transfer of Equity Interests by one of the Company's Subsidiaries and including any sale and leaseback transaction (any of the foregoing, an "Asset Sale"), unless: (1) at least 75% of the total consideration for such Asset Sale or series of related Asset Sales consists of cash or Cash Equivalents; and (2) the Company receives or such Subsidiary receives, as applicable, fair market value for such Asset Sale, such determination to be made in good faith by the Company's Board of Directors for Asset Sales exceeding $2,000,000. Solely for purposes of (1) above, (a) any Indebtedness (other than Subordinated Indebtedness) of the Company or such Subsidiary that is expressly assumed by the transferee in such Asset Sale and with respect to which the Company is and its Subsidiaries are fully and unconditionally released from any and all obligations in connection therewith, (b) property that within 30 days of such Asset Sale is converted into cash or Cash Equivalents; provided, that such cash and Cash Equivalents shall be treated as Net Cash Proceeds attributable to the original Asset Sale for which such property was received, and (c) the fair market value, as determined in good faith by the Board of Directors, of any asset (other than securities) received by the Company or any Subsidiary that, in the good faith reasonable judgment of the Company's Board of Directors, will immediately constitute or be a part of a Related Business shall be deemed to be cash or Cash Equivalents. Within 360 days following such Asset Sale, the Net Cash Proceeds therefrom are: (a) invested in fixed assets and property (other than notes, bonds, obligations and other securities, except in connection with the acquisition of a Guarantor in a Related Business) that in the good faith reasonable judgment of the Company's Board of Directors will immediately constitute or be a part of a Related Business of the Company or such Subsidiary (if it continues to be a Subsidiary) immediately following such transaction; or (b) used to retire Purchase Money Indebtedness secured by the asset that was the subject of the Asset Sale or to permanently reduce the amount of Indebtedness outstanding under the Credit Agreement; or (c) applied to the optional redemption of the Notes in accordance with the terms of this Indenture and the Company's other Indebtedness ranking on a parity with the Notes and with similar provisions requiring the Company to redeem such Indebtedness with the proceeds from such Asset Sale, pro rata in proportion to the respective principal amounts (or accreted values in the case of Indebtedness issued with an original issue discount) of the Notes and such other Indebtedness then outstanding. 64 Pending the final application of any Net Cash Proceeds, the Company may temporarily reduce revolving credit borrowings or otherwise invest the Net Cash Proceeds in any manner that is not prohibited by this Indenture. The accumulated Net Cash Proceeds from Asset Sales not applied as set forth in (a), (b) or (c) of the preceding paragraph shall constitute "Excess Proceeds". Within 30 days after the date that the amount of Excess Proceeds exceeds $10,000,000, the Company shall apply the Excess Proceeds (the "Asset Sale Offer Amount") to the repurchase of the Notes and such other Indebtedness ranking on a parity with the Notes and with similar provisions requiring the Company to make an offer to purchase such Indebtedness with the proceeds from such Asset Sale pursuant to a cash offer (subject only to conditions required by applicable law, if any) (pro rata in proportion to the respective principal amounts (or accreted values in the case of Indebtedness issued with an original issue discount) of the Notes and such other Indebtedness then outstanding) (the "Asset Sale Offer") at a purchase price of 100% of the principal amount (or accreted value in the case of Indebtedness issued with an original issue discount) (the "Asset Sale Offer Price") together with accrued and unpaid interest and Liquidated Damages, if any, to the date of payment. Each Asset Sale Offer shall remain open for 20 Business Days following its commencement (the "Asset Sale Offer Period"). Upon expiration of the Asset Sale Offer Period, the Company shall apply the Asset Sale Offer Amount plus an amount equal to accrued and unpaid interest and Liquidated Damages, if any, to the purchase of all Indebtedness properly tendered in accordance with the provisions hereof (on a pro rata basis if the Asset Sale Offer Amount is insufficient to purchase all Indebtedness so tendered) at the Asset Sale Offer Price (together with accrued interest and Liquidated Damages, if any). To the extent that the aggregate amount of Notes and such other pari passu Indebtedness tendered pursuant to an Asset Sale Offer is less than the Asset Sale Offer Amount, the Company may use any remaining Net Cash Proceeds as otherwise permitted by this Indenture (other than for making Restricted Payments that are not Investments) and following the consummation of each Asset Sale Offer the Excess Proceeds amount shall be reset to zero. Notwithstanding, and without complying with, the provisions of this Section 4.14: (1) the Company may and its Subsidiaries may, in the ordinary course of business, (a) convey, sell, transfer, assign or otherwise dispose of inventory and other assets acquired and held for resale in the ordinary course of business and (b) liquidate Cash Equivalents; (2) the Company may and its Subsidiaries may convey, sell, transfer, assign or otherwise dispose of assets pursuant to and in accordance with Article V; (3) the Company may and its Subsidiaries may sell or dispose of damaged, worn out or other obsolete personal property in the ordinary course of business so long 65 as such property is no longer necessary for the proper conduct of the Company's business or the business of such Subsidiary, as applicable; (4) the Guarantors may convey, sell, transfer, assign or otherwise dispose of assets to the Company or any Guarantor; (5) the Company may and its Subsidiaries may convey, sell, transfer, assign, or otherwise dispose of assets (or related assets or in related transactions) with a fair market value of less than $250,000; (6) the Company may and each of its Subsidiaries may surrender or waive contract rights or settle, release or surrender contract, tort or other litigation claims in the ordinary course of business or grant (or permit realization of) Liens not prohibited by this Indenture; (7) the Company may and the Company's Subsidiaries may make Permitted Investments (excluding clause (o) in the definition thereof) and Restricted Investments under Section 4.3; and (8) the Company may and the Company's Subsidiaries may exchange assets held by the Company or such Subsidiaries for assets held by any Person or entity; provided, that (a) the assets received by the Company or such Subsidiaries in any such exchange in the good faith reasonable judgment of the Company's Board of Directors will immediately constitute, be a part of, or be used in, a Related Business of the Company or such Subsidiaries, (b) the Company's Board of Directors has determined that the terms of any exchange are fair and reasonable, (c) any such exchange shall be deemed to be an Asset Sale to the extent that the Company or any of the Company's Subsidiaries receives cash or Cash Equivalents in such exchange, and (d) that, in the case of a transaction exceeding $10,000,000 of consideration to any party thereto, the Company shall have obtained a favorable written opinion by an independent financial advisor of national reputation in the United States as to the fairness from a financial point of view to the Company or such Subsidiary of the proposed transaction. In addition to the foregoing and notwithstanding anything herein to the contrary, (A) the Company shall not, and shall not permit any of its Subsidiaries to, directly or indirectly make any Asset Sale of any of the Equity Interests of any of the Company's Subsidiaries (other than to the Company or to a Guarantor) except (i) pursuant to an Asset Sale of all the Equity Interests of such Subsidiary, (ii) for an Asset Sale of Equity Interests with no preferences or special rights or privileges and with no redemption or prepayment provisions, provided, that after such sale the Company or the Company's Subsidiaries own a majority of the voting and economic Equity Interests of such Subsidiary, (iii) to the extent such shares represent directors' qualifying shares or shares required by applicable law to be held by a Person other than the Company or a Wholly Owned Subsidiary of the Company, and (B) in the event of the transfer of substantially all (but not all) of the assets of the Company and its Subsidiaries as an entirety 66 to a Person in a transaction covered by and effected in accordance with Article V, the successor corporation shall be deemed to have sold for cash at fair market value the assets of the Company and its Subsidiaries not so transferred for purposes of this Section 4.14, and shall comply with the provisions of this section with respect to such deemed sale as if it were an Asset Sale (with such fair market value being deemed to be Net Cash Proceeds for such purpose). Any Asset Sale Offer shall be made in compliance with all applicable laws, rules, and regulations, including, if applicable, Regulation 14E of the Exchange Act and the rules and regulations thereunder and all other applicable Federal and state securities laws. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.14, the Company's compliance or the compliance of any of the Company's Subsidiaries with such laws and regulations shall not in and of itself cause a breach of the Company's obligations under this Section 4.14. If the payment date in connection with an Asset Sale Offer hereunder is on or after an interest payment Record Date and on or before the associated Interest Payment Date, any accrued and unpaid interest (and Liquidated Damages, if any, due on such Interest Payment Date) will be paid to the Person in whose name a Note is registered at the close of business on such Record Date. Notice of an Asset Sale Offer shall be sent, on or prior to the commencement of the Asset Sale Offer, by first-class mail, by the Company to each Holder at its registered address, with a copy to the Trustee. The notice to the Holders shall contain all information, instructions and materials required by applicable law or otherwise material to such Holders' decision to tender Notes pursuant to the Asset Sale Offer. The notice, which (to the extent consistent with this Indenture) shall govern the terms of an Asset Sale Offer, shall state: (1) that the Asset Sale Offer is being made pursuant to such notice and this Section 4.14; (2) the Asset Sale Offer Amount, the Asset Sale Offer Price (including the amount of accrued but unpaid interest (and Liquidated Damages, if any)), and the date of purchase; (3) that any Note or portion thereof not tendered or accepted for payment will continue to accrue interest (and Liquidated Damages, if any) if interest (and Liquidated Damages, if any) is then accruing; (4) that, unless the Company defaults in depositing cash with the Paying Agent (which may not for purposes of this Section 4.14, notwithstanding anything in this Indenture to the contrary, be the Company or any Affiliate of the Company) in accordance with the last paragraph of this Section 4.14, any Note, or portion thereof, accepted for payment pursuant to the Asset Sale Offer shall cease to accrue interest (and Liquidated Damages, if any) after the payment date in connection with an Asset Sale; 67 (5) that Holders electing to have a Note, or portion thereof, purchased pursuant to an Asset Sale Offer will be required to surrender their Note, with the form entitled "Option of Holder to Elect Purchase" on the reverse of the Note completed, to the Paying Agent (which may not for purposes of this Section 4.14, notwithstanding any other provision of this Indenture, be the Company or any Affiliate of the Company) at the address specified in the notice; (6) that Holders will be entitled to withdraw their elections, in whole or in part, if the Paying Agent receives, prior to the expiration of the Asset Sale Offer, a facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Notes the Holder is withdrawing and a statement containing a facsimile signature and stating that such Holder is withdrawing his election to have such principal amount of the Notes purchased; (7) that if Indebtedness in an aggregate principal amount in excess of the aggregate principal amount of Notes to be acquired pursuant to the Asset Sale Offer is tendered and not withdrawn, the Company shall purchase such Indebtedness on a pro rata basis in proportion to the respective principal amounts (or accreted values in the case of Indebtedness issued with an original issue discount) thereof (with such adjustments as may be deemed appropriate by the Company so that only Notes in denominations of $1,000 or integral multiples of $1,000 shall be acquired); (8) that Holders whose Notes were purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered; and (9) the circumstances and relevant facts regarding such Asset Sale. On or before the date of purchase, the Company shall (i) accept for payment Notes or portions thereof properly tendered pursuant to the Asset Sale Offer (on a pro rata basis if required pursuant to paragraph (7) above), (ii) deposit with the Paying Agent cash sufficient to pay the Asset Sale Offer Price for all Notes or portions thereof so accepted and (iii) deliver to the Trustee Notes so accepted together with an Officers' Certificate setting forth the Notes or portions thereof being purchased by the Company. The Paying Agent shall promptly mail or deliver to Holders of Notes so accepted payment in an amount equal to the Asset Sale Offer Price for such Notes, and the Trustee shall promptly authenticate and mail or deliver to such Holders a new Note equal in principal amount to any unpurchased portion of the Note surrendered. Any Notes not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof. SECTION 4.15. WAIVER OF STAY, EXTENSION OR USURY LAWS Each of the Company and the Guarantors 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 68 claim or take the benefit or advantage of, any stay or extension law or any usury law or other law which would prohibit or forgive the Company or any Guarantor from paying all or any portion of the principal of, premium of, or interest (or Liquidated Damages, if any) on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Indenture; and (to the extent that it may lawfully do so) each of the Company and the Guarantors hereby expressly waives all benefit or advantage of any such law and covenants that it shall not 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 had been enacted. SECTION 4.16. LIMITATION ON LIENS SECURING INDEBTEDNESS The Company and the Guarantors shall not, and neither the Company nor the Guarantors shall permit any of their respective Subsidiaries to, create, incur, assume or suffer to exist any Lien of any kind, other than Permitted Liens, upon any of their respective assets now owned or acquired on or after the date of this Indenture or upon any income or profits therefrom, unless the Company provides, and causes its Subsidiaries to provide, concurrently therewith, that the Notes and the applicable Guarantees are equally and ratably so secured; provided, that if such Indebtedness is Subordinated Indebtedness, the Lien securing such Subordinated Indebtedness shall be contractually subordinate and junior to the Lien securing the Notes (and any related applicable Guarantees) with the same relative priority as such Subordinated Indebtedness shall have with respect to the Notes (and any related applicable Guarantees). SECTION 4.17. LIMITATIONS ON LINES OF BUSINESS Neither the Company nor any of its Subsidiaries shall directly or indirectly engage to any substantial extent in any line or lines of business activity other than that which, in the reasonable good faith judgment of the Company's Board of Directors, is a Related Business. SECTION 4.18. SALE AND LEASEBACK TRANSACTIONS The Company will not, and will not permit any of its Subsidiaries to, enter into any sale and leaseback transaction; provided that the Company and its Subsidiaries may enter into a sale and leaseback transaction if: (1) the Company or such Subsidiary could have (a) incurred Indebtedness in an amount equal to the Attributable Indebtedness relating to such sale and leaseback transaction under the Debt Incurrence Ratio in the second paragraph of Section 4.11 and (b) incurred a Lien to secure such Indebtedness pursuant to the covenant described in Section 4.16; 69 (2) the gross cash proceeds of such sale and leaseback transaction are at least equal to the fair market value, as determined in good faith by the Board of Directors and set forth in an Officers' Certificate delivered to the Trustee, of the property that is the subject of such sale and leaseback transaction; and (3) the transfer of assets in such sale and leaseback transaction is permitted by, and the Company applies the proceeds of such transaction in compliance with, Section 4.14. SECTION 4.19.

SECTION 4.20. DESIGNATION OF UNRESTRICTED SUBSIDIARIES (a) The Board of Directors of the Company may designate any Subsidiary (including any newly acquired or newly formed Subsidiary) that does not directly, indirectly or beneficially own any Capital Stock of, or Subordinated Indebtedness of, or own or hold any Lien on any property of, the Company or any other Subsidiary of the Company, to be an Unrestricted Subsidiary so long as (a) such Subsidiary at the time of such designation: (i) has no Indebtedness other than Non-Recourse Indebtedness; provided, that the Company or a Subsidiary of the Company may guarantee Indebtedness of an Unrestricted Subsidiary so long as any such guarantee constitutes an Investment made pursuant to clause (f) of the definition of Permitted Investment; (ii) is not party to any agreement, contract, arrangement or understanding with the Company or any Subsidiary of the Company unless the terms of any such agreement, contract, arrangement or understanding are no less favorable to the Company or such Subsidiary than those that might be obtained at the time from Persons who are not Affiliates of the Company; (iii) is a Person with respect to which neither the Company nor any of its Subsidiaries has any direct or indirect obligation (x) to subscribe for additional Equity Interests, except to the extent that any such Investment made for such purpose constitutes an Investment made pursuant to clause (f) of the definition of Permitted Investment, or (y) to maintain or preserve such Person's financial condition or to cause such Person to achieve any specified levels of operating results; and (iv) has not guaranteed or otherwise directly or indirectly provided credit support for any Indebtedness of the Company or any of its Subsidiaries; and (b) each Subsidiary of such Subsidiary shall also be designated an Unrestricted Subsidiary and shall comply with clause (a) above. 70 (b) The Board of Directors of the Company may designate any Unrestricted Subsidiary to be a Subsidiary, provided, that (a) no Default or Event of Default is existing or will occur as a consequence thereof and (b) immediately after giving effect to such designation, on a pro forma basis, the Company could incur at least $1.00 of Indebtedness pursuant to the Debt Incurrence Ratio.

For purposes of the foregoing, the transfer (by lease, assignment, sale or otherwise) of all or substantially all of the properties and assets of one or more Subsidiaries, the Company's interest in which constitutes all or substantially all of the Company's properties and assets, shall be deemed to be the transfer of all or substantially all of the Company's properties and assets. SECTION 5.2. SUCCESSOR CORPORATION SUBSTITUTED Upon any consolidation or merger or any transfer of all or substantially all of the assets of the Company in accordance with Section 5.1, the successor entity formed by such consolidation or into which the Company is merged or to which such transfer is made shall succeed to and (except in the case of a lease or any transfer of all or substantially all of the Company's assets) be substituted for, and may exercise every right and power of, the Company under this Indenture with the same effect as if such successor entity had been named therein as the Company, and (except in the case of a lease or any transfer or all or substantially all of the Company's assets) the Company shall be released from the obligations under the Notes and this Indenture except with respect to any obligations that arise from, or are related to, such transaction.

The Holders of a majority in aggregate principal amount of the then outstanding Notes, by written notice to the Trustee, may rescind any acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default, other than the non-payment of the principal of, premium, if any, and interest, if any, on the Notes that have become due solely because of the acceleration, and except a Default with respect to any provision requiring a supermajority approval to amend, which Default may only be waived by such a supermajority, have been cured or waived as provided in Section 6.12. SECTION 6.3. COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE The Company covenants that if an Event of Default in payment of principal, premium or interest specified in clause (1) or (2) of Section 6.1 hereof occurs and is continuing, the Company shall, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Notes, the whole amount then due and payable on such Notes for principal, premium (if any), and interest (and Liquidated Damages, if any), and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal (and premium, if any), and on any overdue interest (and Liquidated Damages, if any), at the rate borne by the Notes, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including compensation to, and expenses, disbursements and advances of the Trustee and its agents and counsel and all other amounts due the Trustee under Section 7.7. 74 If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust in favor of the Holders, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon the Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon the Notes, wherever situated. If an Event of Default occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders by such appropriate judicial proceedings as the Trustee shall deem most effective to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy. SECTION 6.4. TRUSTEE MAY FILE PROOFS OF CLAIM In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Notes or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue principal, premium, if any, or interest (and Liquidated Damages, if any)) shall be entitled and empowered, by intervention in such proceeding or otherwise to take any and all actions under the TIA, including (1) to file and prove a claim for the whole amount of principal (and premium, if any) and interest (and Liquidated Damages, if any) owing and unpaid in respect of the Notes and to file such 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 and its agent and counsel and all other amounts due the Trustee under Section 7.7) and of the Holders allowed in such judicial proceeding, and (2) to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee and its agents and counsel, and any other amounts due the Trustee under Section 7.7 hereof. 75 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 thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. SECTION 6.5. TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF NOTES All rights of action and claims under this Indenture or the Notes may be prosecuted and enforced by the Trustee without the possession of any of the Notes or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust in favor of the Holders, and any recovery of judgment shall, after provision for the payment of compensation to, and expenses, disbursements and advances of the Trustee and its agents and counsel and all other amounts due the Trustee under Section 7.7, be for the ratable benefit of the Holders of the Notes in respect of which such judgment has been recovered. SECTION 6.6. PRIORITIES Any money collected by the Trustee pursuant to this Article VI shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal, premium (if any), or interest (or Liquidated Damages, if any), upon presentation of the Notes and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: FIRST: To the Trustee in payment of all amounts due pursuant to Section 7.7 hereof; SECOND: To the Holders in payment of the amounts then due and unpaid for principal of, premium (if any), and interest (and Liquidated Damages, if any) on, the Notes in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Notes for principal, premium (if any), and interest (and Liquidated Damages, if any), respectively; and THIRD: To the Company, the Guarantors or such other Person as may be lawfully entitled thereto, the remainder, if any, each as their respective interests may appear. The Trustee may, but shall not be obligated to, fix a record date and payment date for any payment to the Holders under this Section 6.6. 76 SECTION 6.7. LIMITATION ON SUITS No Holder of any Note shall have any right to order or direct the Trustee to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless (A) such Holder has previously given written notice to the Trustee of a continuing Event of Default; (B) the Holders of not less than 25% in aggregate principal amount of then outstanding Notes shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; (C) such Holder or Holders have offered to the Trustee security or indemnity reasonably satisfactory to it against the costs, expenses and liabilities to be incurred or reasonably probable to be incurred in compliance with such request; (D) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and (E) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in aggregate principal amount of the outstanding Notes; it being understood and intended that no one or more Holders shall have any right in any manner whatsoever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other Holders, or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all the Holders. SECTION 6.8. UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM AND INTEREST Notwithstanding any other provision of this Indenture, the Holder of any Note shall have the right, which is absolute and unconditional, to receive payment of the principal of, and premium (if any), and interest (and Liquidated Damages, if any) on, such Note on the Maturity Dates of such payments as expressed in such Note (in the case of redemption, the Redemption Price on the applicable Redemption Date, in the case of a Change of Control, the Change of Control Purchase Price on the Change of Control Purchase Date, and in the case of an Asset Sale, the Asset Sale Offer Price on the relevant purchase date) and to institute suit for the enforcement of any such payment after such respective dates, and such rights shall not be impaired without the consent of such Holder. 77 SECTION 6.9. RIGHTS AND REMEDIES CUMULATIVE Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in Section 2.7 hereof, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. SECTION 6.10. DELAY OR OMISSION NOT WAIVER No delay or omission by the Trustee or by any Holder of any Note to exercise any right or remedy arising upon any Event of Default shall impair the exercise of any such right or remedy or constitute a waiver of any such Event of Default. Every right and remedy given by this Article VI or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be. SECTION 6.11. CONTROL BY HOLDERS The Holder or Holders of a majority in aggregate principal amount of then outstanding Notes shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred upon the Trustee, provided, that: (1) such direction shall not be in conflict with any applicable rule of law or with this Indenture; (2) the Trustee shall not determine that the action so directed would be unjustly prejudicial to the Holders not taking part in such direction; and (3) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. SECTION 6.12. WAIVER OF EXISTING OR PAST DEFAULT Subject to Section 6.8, the Holder or Holders of not less than a majority in aggregate principal amount of the outstanding Notes may, on behalf of all Holders, waive any existing or past Default and its consequences under this Indenture, except a continuing Default (A) with respect to any provision requiring a supermajority approval to amend, which Default may only be waived by such supermajority; or 78 (B) in the payment of the principal of, or interest on, any Note as specified in clauses (1) and (2) of Section 6.1 hereof and not yet cured; or (C) with respect to any covenant or provision hereof which, under Article IX, cannot be modified or amended without the consent of the Holder of each outstanding Note affected. 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 the exercise of any right arising from such Default or Event of Default. SECTION 6.13. UNDERTAKING FOR COSTS All parties to this Indenture agree, and each Holder of any Note by his acceptance thereof shall be deemed to have agreed, that 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, suffered or omitted to be taken by it as Trustee, any court may in its discretion require the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys' fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section 6.13 shall not apply to any suit instituted by the Company, to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in aggregate principal amount of the outstanding Notes, or to any suit instituted by any Holder for enforcement of the payment of principal of, or premium (if any), or interest (or Liquidated Damages, if any) on, any Note on or after the respective Maturity Date expressed in such Note (including, in the case of redemption, on or after the Redemption Date). SECTION 6.14. RESTORATION OF RIGHTS AND REMEDIES If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every case, subject to any determination in such proceeding, the Company, the Guarantors, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted. 79 ARTICLE VII TRUSTEE The Trustee hereby accepts the trust imposed upon it by this Indenture and covenants and agrees to perform the same, as herein expressed, subject to the terms hereof. SECTION 7.1. DUTIES OF TRUSTEE (a) If a Default or 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 their exercise as a prudent Person would exercise or use under the circumstances in the conduct of his or her own affairs. (b) Except during the continuance of a Default or an Event of Default: (1) the Trustee need perform only those duties as are specifically set forth in this Indenture and no others, and no covenants or obligations shall be implied in or read into this Indenture which are adverse to the Trustee, and (2) 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 which 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 (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein). (c) The Trustee shall not be relieved from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that: (1) this paragraph does not limit the effect of paragraph (b) of this Section 7.1; (2) the Trustee shall not be liable for any error of judgment made in good faith by a Trust Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and (3) 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 6.11 hereof. (d) No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or to take or omit to take any action under this Indenture or at the request, order or 80 direction of the Holders or in the exercise of any of its rights or powers if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. (e) Every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b), (c), (d) and (f) of this Section 7.1. (f) The Trustee shall not be liable for interest on any assets received by it except as the Trustee may agree in writing with the Company (including without limitation to the extent the Trustee receives funds prior to the interest payment date in order to comply with the provisions of Section 4.1). Assets held in trust by the Trustee need not be segregated from other assets except to the extent required by law. SECTION 7.2. RIGHTS OF TRUSTEE Subject to Section 7.1 hereof: (a) In the absence of bad faith, the Trustee may conclusively rely on any document reasonably 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 such document. (b) Before the Trustee acts or refrains from acting, it may consult with counsel and may require an Officers' Certificate or an Opinion of Counsel, which shall conform to Sections 12.4 and 12.5 hereof. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such certificate or advice of counsel. (c) 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. (d) The Trustee shall not be liable for any action it or its agent takes or omits to take in good faith which it reasonably believes to be authorized or within its rights or powers conferred upon it by this Indenture; provided, however, that the Trustee's conduct does not constitute willful misconduct or gross negligence. (e) The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, notice, request, direction, consent, order, bond, debenture or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit. (f) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or direction of any of the Holders, pursuant to the provisions of this Indenture, unless such Holders shall have offered to the 81 Trustee reasonable security or indemnity reasonably satisfactory to it against the costs, expenses and liabilities which may be incurred therein or thereby. (g) Unless otherwise specifically provided for in this Indenture, any demand, request, direction or notice from the Company or any Guarantor shall be sufficient if signed by an Officer of the Company or such Guarantor, as applicable. (h) The Trustee shall have no duty to inquire as to the performance of the Company's or any Guarantor's covenants in Article IV hereof or as to the performance by any Agent of its duties hereunder. In addition, the Trustee shall not be deemed to have knowledge of any Default or Event of Default except (i) any Event of Default occurring pursuant to Sections 6.1(1), 6.1(2) and 4.1 hereof, or (ii) any Default or Event of Default of which the Trustee shall have received written notification or obtained actual knowledge. (i) Whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, rely upon an Officers' Certificate, an Opinion of Counsel, or both. (j) The Trustee may request that the Issuer or the Company deliver an Officers' Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which Officers' Certificate may be signed by any person authorized to sign an Officers' Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded. SECTION 7.3. 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, any Guarantor, any of their Subsidiaries, or their respective Affiliates with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. However, the Trustee must comply with Sections 7.10 and 7.11 hereof. SECTION 7.4. TRUSTEE'S DISCLAIMER The Trustee makes no representation as to the validity or adequacy of this Indenture or the Notes and it shall not be accountable for the Company's use of the proceeds from the Notes, and it shall not be responsible for any statement in the Notes, other than the Trustee's certificate of authentication, or the use or application of any funds received by a Paying Agent other than the Trustee. 82 SECTION 7.5. NOTICE OF DEFAULT If a Default or an Event of Default occurs and is continuing and if it is known to the Trustee, the Trustee shall mail to each Securityholder notice of the uncured Default or Event of Default within 90 days after such Default or Event of Default occurs. SECTION 7.6. REPORTS BY TRUSTEE TO HOLDERS Within 60 days after each May 15 beginning with the May 15 following the date of this Indenture, the Trustee shall, if required by law, mail to each Securityholder a brief report dated as of such May 15 that complies with TIA Section 313(a). The Trustee also shall comply with TIA Sections 313(b) and 313(c). The Company shall promptly notify the Trustee in writing if the Notes become listed on any stock exchange or automatic quotation system or of any delisting thereof. A copy of each report at the time of its mailing to Securityholders shall be mailed to the Company and filed with the SEC and each stock exchange, if any, on which the Notes are listed. SECTION 7.7. COMPENSATION AND INDEMNITY The Company and the Guarantors jointly and severally agree to pay to the Trustee from time to time such compensation for its services as the Company and the Trustee shall from time to time agree in writing. The Trustee's compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company and the Guarantors shall reimburse the Trustee upon request for all reasonable disbursements, expenses and advances incurred or made by it in accordance with this Indenture. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee's agents, accountants, experts and counsel. The Company and the Guarantors jointly and severally agree to indemnify each of the Trustee (in its capacity as Trustee) and each predecessor Trustee and each of its officers, directors, attorneys-in-fact and agents for, and hold it harmless against, any claim, demand, expense (including but not limited to reasonable compensation, disbursements and expenses of the Trustee's agents and counsel), loss or liability incurred by it without negligence or bad faith on the part of the Trustee, arising out of or in connection with the acceptance and the administration of this trust and its rights or duties hereunder, including the reasonable costs and expenses of defending itself against any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder. The Trustee shall notify the Company promptly of any claim asserted against the Trustee for which it may seek indemnity; provided, however, that any failure to so notify the Company shall not relieve the Company or any Guarantor of its indemnity obligations hereunder. The Company and the Guarantors shall defend the claim and the Trustee shall provide reasonable cooperation at the Company's and the Guarantors' expense in the defense. The Trustee may have separate counsel and the Company and the Guarantors shall pay the reasonable fees and expenses of such counsel; provided, that 83 the Company and the Guarantors will not be required to pay such fees and expenses if they assume the Trustee's defense and if the Trustee is advised by counsel that there is no conflict of interest between the Company and the Guarantors and the Trustee in connection with such defense. The Company and the Guarantors need not pay for any settlement made without their written consent, which shall not be unreasonably withheld. The Company and the Guarantors need not reimburse any expense or indemnify against any loss or liability to the extent incurred by the Trustee through its negligence, bad faith or willful misconduct. To secure the Company's and the Guarantors' payment obligations in this Section 7.7, the Trustee shall have a lien prior to the Notes on all assets held or collected by the Trustee, in its capacity as Trustee, except assets held in trust to pay principal and premium, if any, of or interest on particular Notes. When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.1(4) or (5) of this Indenture occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law. The Company's and the Guarantors' obligations under this Section 7.7 and any lien arising hereunder shall survive the resignation or removal of the Trustee, the discharge of the Company's and the Guarantors' obligations pursuant to Article VIII of this Indenture and any rejection or termination of this Indenture under any Bankruptcy Law. SECTION 7.8. REPLACEMENT OF TRUSTEE The Trustee may resign by so notifying the Company in writing. The Holder or Holders of a majority in aggregate principal amount of the outstanding Notes may remove the Trustee by so notifying the Company and the Trustee in writing and may appoint a successor trustee with the Company's consent. The Company may remove the Trustee if: (a) the Trustee fails to comply with Section 7.10 hereof; (b) the Trustee is adjudged bankrupt or insolvent; (c) a receiver, Custodian or other public officer takes charge of the Trustee or its property; or (d) the Trustee becomes incapable of acting. If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holder or Holders of a majority in principal amount of the Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Company. 84 A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Immediately after that and provided that all sums owing to the retiring Trustee provided for in Section 7.7 hereof have been paid, the retiring Trustee shall transfer all property held by it as trustee to the successor Trustee, subject to the lien, if any, provided in Section 7.7 hereof, 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. A successor Trustee shall mail notice of its succession to each Holder. If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee (at the Company's cost and expense), the Company or the Holder or Holders of at least 10% in aggregate principal amount of the outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee. If the Trustee fails to comply with Section 7.10 hereof, any Securityholder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. Notwithstanding replacement of the Trustee pursuant to this Section 7.8, the Company's and the Guarantors' obligations under Section 7.7 hereof shall continue for the benefit of the retiring Trustee. SECTION 7.9. SUCCESSOR TRUSTEE BY MERGER, ETC. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the resulting, surviving or transferee corporation without any further act shall, if such resulting, surviving or transferee corporation is otherwise eligible hereunder, be the successor Trustee. SECTION 7.10. ELIGIBILITY; DISQUALIFICATION The Trustee shall at all times satisfy the requirements of TIA Section 310(a)(1), (2) and (5). The Trustee shall have a combined capital and surplus of at least $25,000,000, as set forth in its most recent published annual report of condition. The Trustee shall comply with TIA Section 310(b). SECTION 7.11. PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY. The Trustee shall comply with TIA Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee who has resigned or been removed shall be subject to TIA Section 311(a) to the extent indicated. 85 ARTICLE VIII LEGAL DEFEASANCE AND COVENANT DEFEASANCE AND SATISFACTION AND DISCHARGE SECTION 8.1. OPTION TO EFFECT LEGAL DEFEASANCE OR COVENANT DEFEASANCE The Company may elect to have Section 8.2, at the Company's option and at any time, or Section 8.3, at the Company's option and at any time, of this Indenture applied to all outstanding Notes upon compliance with the conditions set forth below in this Article VIII. SECTION 8.2. LEGAL DEFEASANCE AND DISCHARGE Upon the Company's exercise under Section 8.1 hereof of the option applicable to this Section 8.2, the Company and the Guarantors shall be deemed to have been discharged from their respective obligations with respect to all outstanding Notes and Guarantees on the date the conditions set forth below are satisfied (hereinafter, "Legal Defeasance"). For this purpose, such Legal Defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by the Notes, and this Indenture shall cease to be of further effect as to all outstanding Notes and Guarantees, except as to be deemed to be "outstanding" only for the purposes of the Sections of this Indenture referred to in (a) and (b) below, and the Company and the Guarantors shall be deemed to have satisfied all other of their respective obligations under such Notes and this Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder: (a) the rights of Holders of outstanding Notes to receive payments in respect of the principal of, premium, if any, and interest (and Liquidated Damages, if any) on such Notes when such payments are due from the trust described in Section 8.5, (b) the Company's obligations with respect to such Notes under Sections 2.3, 2.4, 2.6, 2.7, 2.10, 4.2, 8.5, 8.6 and 8.7 hereof, and (c) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Company's obligations in connection therewith. Subject to compliance with this Article VIII, the Company may exercise its option under this Section 8.2 notwithstanding the prior exercise of its option under Section 8.3 hereof with respect to the Notes. SECTION 8.3. COVENANT DEFEASANCE Upon the Company's exercise under Section 8.1 hereof of the option applicable to this Section 8.3, the Company and the Guarantors shall be released from their respective obligations under the covenants contained in Sections 4.3, 4.6, 4.8, 4.10, 4.11, 4.12, 4.13, 4.14, 4.16, 4.17, 4.18, 4.19 and 4.20, Article V, Article X and the third and fourth paragraphs of Section 11.1(a) 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 86 shall continue to be deemed "outstanding" for all other purposes hereunder. For this purpose, such Covenant Defeasance means that, with respect to the outstanding Notes, neither the Company nor any Guarantor need comply with and shall have any 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 6.1(3), 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 8.1 hereof of the option applicable to this Section 8.3, and subject to Section 8.4, Sections 6.1(6) through 6.1(8) hereof shall not constitute Events of Default with respect to the Notes. SECTION 8.4. CONDITIONS TO LEGAL OR COVENANT DEFEASANCE The following shall be the conditions to the application of either Section 8.2 or 8.3 hereof to the outstanding Notes: (a) (i) The Company shall irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of the Notes, U.S. legal tender, U.S. Government Obligations 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, if any) on such Notes on the stated date for payment thereof or on the redemption date of such principal or installment of principal of, premium, if any, or interest (and Liquidated Damages, if any) on such Notes, and the Trustee must have, for the benefit of the Holders of Notes, a valid, perfected, exclusive security interest in such trust; (ii) in the case of Legal Defeasance, the Company shall have delivered to the Trustee an opinion of counsel in the United States reasonably acceptable to the Trustee confirming that: (A) the Company has received from, or there has been published by the Internal Revenue Service, a ruling or (B) since the date of this Indenture, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such opinion of counsel shall confirm that, the Holders of such 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; (iii) in the case of Covenant Defeasance, the Company shall have delivered to the Trustee an opinion of counsel in the United States reasonably acceptable to such Trustee confirming that the Holders of such 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; (iv) no Default or Event of Default (other than a Default resulting from the borrowing of funds to be applied to such deposit and the grant of any Lien securing such borrowing) shall have occurred and be continuing on the date of such deposit or insofar as Events of Default from bankruptcy or insolvency events are concerned, at any time in the period ending on the 91st day 87 after the date of deposit; (v) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under this Indenture (other than a Default resulting from the borrowing of funds to be applied to such deposit and the grant of any Lien securing such borrowing) or any other material agreement or instrument to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound; (vi) 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 such Notes over any other creditors of the Company or with the intent of defeating, hindering, delaying or defrauding any other creditors of the Company or others; and (vii) the Company shall have delivered to the Trustee an Officers' Certificate and an opinion of counsel, each stating that the conditions precedent provided for in, in the case of the Officers' Certificate, (i) through (vi) and, in the case of the opinion of counsel, clauses (i) (with respect to the validity and perfection of the security interest), (ii), (iii) and (v) of this paragraph have been complied with and the Company shall have delivered to the Trustee an Officers' Certificate, subject to such qualifications and exceptions as the Trustee deems appropriate, to the effect that, assuming no Holder of the Notes is an insider of the Company, the trust funds will not be subject to the effect of any applicable Federal bankruptcy, insolvency, reorganization or similar laws affecting creditors' rights generally. Any Legal Defeasance or Covenant Defeasance shall be effective on the earlier of (i) the 91st day after the date of such deposit, and (ii) the day on which all of the conditions set forth in this Section 8.4 have been satisfied. If the funds deposited with the Trustee to effect Covenant Defeasance are insufficient to pay the principal of, premium, if any, and interest (and Liquidated Damages, if any) on the Notes when due, or if any court enters an order directing the repayment of the deposit to the Company or otherwise making the deposit unavailable to make payments under the Notes when due, then (so long as the insufficiency exists or the order remains in effect) the obligations of the Company and the Guarantors under this Indenture will be revived and no such defeasance will be deemed to have occurred. SECTION 8.5. DEPOSITED CASH AND U.S. GOVERNMENT OBLIGATIONS TO BE HELD IN TRUST; OTHER MISCELLANEOUS PROVISIONS Subject to Section 8.6 hereof, all cash and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.5, the "Paying Agent") pursuant to Section 8.4 hereof in respect of the outstanding Notes shall be held in trust and applied by the Paying Agent, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any other 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, if any), 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 U.S. Government Obligations deposited pursuant to 88 Section 8.4 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 outstanding Notes. SECTION 8.6. REPAYMENT TO THE COMPANY (a) Anything in this Article VIII to the contrary notwithstanding, the Trustee or the Paying Agent shall deliver or pay to the Company from time to time upon the request of the Company any cash or U.S. Government Obligations held by it as provided in Section 8.4 hereof which, 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 8.4(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. (b) Any cash and U.S. Government Obligations (including the proceeds thereof) 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 (and Liquidated Damages, if any) on any Note and remaining unclaimed for two years after such principal, and premium, if any, or interest (and Liquidated Damages, if any) has become due and payable shall be paid to the Company on its request; and the Holder of such Note shall thereafter look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money 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. SECTION 8.7. REINSTATEMENT If the Trustee or Paying Agent is unable to apply any cash or U.S. Government Obligations in accordance with Section 8.2 or 8.3 hereof, as the case may be, of this Indenture by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company's and the Guarantors' obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.2 or 8.3 hereof until such time as the Trustee or Paying Agent is permitted to apply such money in accordance with Sections 8.2 and 8.3 hereof, as the case may be; provided, however, that, if the Company makes any payment of principal of, premium, if any, or interest (and Liquidated Damages, if any) 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 cash or U.S. Government Obligations held by the Trustee or Paying Agent. 89 SECTION 8.8. SATISFACTION AND DISCHARGE (a) All outstanding Notes have been delivered to the Trustee for cancellation; or (b)(1) the Company has given irrevocable and unconditional notice of redemption for all of the outstanding Notes under Article III hereof, or all outstanding Notes have otherwise become due and payable, and we have irrevocably deposited or caused to be deposited with the Trustee an amount of money sufficient to pay and discharge the entire Indebtedness (including all principal, premium, if any, and accrued interest, and Liquidated Damages, if any) on all outstanding Notes, (2) the Company has delivered irrevocable instructions to the Trustee to apply the deposited money toward the payment of the Notes at maturity or the redemption date, as the case may be, (3) the Trustee, for the benefit of the Holders of the Notes, has a valid, perfected, exclusive security interest in the trust, (4) the deposit does and will not result in a breach or violation of, or constitute a default under this Indenture or any other material agreement or instrument to which the Company or any of its Subsidiaries is a party or is otherwise bound, (5) the Company has paid all other amounts payable by it under this Indenture, and (6) the Company has delivered to the Trustee and Officers' Certificate stating that the deposit was not made by it with the intent to hinder, delay, or defraud any other of its creditors. The Company must also deliver to the Trustee an Officers' Certificate and an Opinion of Counsel confirming the satisfaction of the conditions in clauses (3) (with respect to the validity and perfection of the security interest) and (4) above. ARTICLE IX AMENDMENTS, SUPPLEMENTS AND WAIVERS SECTION 9.1. SUPPLEMENTAL INDENTURES WITHOUT CONSENT OF HOLDERS Without the consent of any Holder, the Company or any Guarantor, when authorized by Board Resolutions, and the Trustee, at any time and from time to time, may enter into one or more indentures supplemental hereto, in form satisfactory to the Trustee, for any of the following purposes: (1) to cure any ambiguity, defect, or inconsistency; 90 (2) to add to the covenants of the Company or the Guarantors for the benefit of the Holders, or to surrender any right or power herein conferred upon the Company or the Guarantors; (3) to provide for collateral for or additional Guarantors of the Notes; (4) to evidence the succession of another Person to the Company, and the assumption by any such successor of the obligations of the Company, herein and in the Notes in accordance with Article V; (5) to comply with the TIA; (6) to evidence the succession of another corporation to any Guarantor and assumption by any such successor of the Guarantee of such Guarantor (as set forth in Section 11.4) in accordance with Article XI; (7) to evidence the release of any Guarantor in accordance with Article XI; (8) to evidence and provide for the acceptance of appointment hereunder by a successor Trustee with respect to the Notes; (9) in any other case where a supplemental indenture is required or permitted to be entered into pursuant to the provisions of this Indenture without the consent of any Holder; (10) to provide for the issuance and authorization of the Exchange Notes; or (11) to make any change that does not adversely affect the rights of any Holder. SECTION 9.2. AMENDMENTS, SUPPLEMENTAL INDENTURES AND WAIVERS WITH CONSENT OF HOLDERS Subject to Section 6.8 hereof, with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes then outstanding (including consents obtained in connection with a tender offer or exchange offer for such Notes), by written act of said Holders delivered to the Company and the Trustee, the Company and the Guarantors, when authorized by Board Resolutions, and the Trustee may amend or supplement this Indenture or enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of modifying in any manner the rights of the Holders under this Indenture or the Notes. Subject to Section 6.8, the Holder or Holders of not less than a majority in aggregate principal amount of Notes then outstanding may waive compliance by the Company or any Guarantor with any provision of this Indenture or the Notes. 91 Notwithstanding any of the above, however, no such amendment, supplemental indenture or waiver shall, without the consent of Holders of at least 66 2/3% in aggregate principal amount of the Notes then outstanding, modify the provisions (including the defined terms used therein) governing the terms of the Guarantees or, except as set forth in clause (1) below, the provisions (including the defined terms used therein) of Article X, in either case in a manner adverse to the Holders. Notwithstanding any of the above, however, no such amendment, supplemental indenture or waiver shall, without the consent of the Holder of each outstanding Note affected thereby: (1) change the Stated Maturity on any Note, or reduce the principal amount thereof or the rate (or extend the time for payment) of interest thereon or any premium payable upon the redemption thereof at the Company's option, or change the city of payment where, or the coin or currency in which, any Note or any premium or the interest thereon is payable, or impair the right to institute suit for the enforcement of any such payment on or after the Stated Maturity thereof (or, in the case of redemption at the Company's option, on or after the Redemption Date), or after an Asset Sale or Change of Control has occurred, reduce the Change of Control Purchase Price or the Asset Sale Offer Price with respect to the corresponding Asset Sale or Change of Control or alter the provisions (including the defined terms used therein) regarding the Company's right to redeem the Notes as a right, or at the Company's option, in a manner adverse to the Holders; or (2) reduce the percentage in principal amount of the outstanding Notes, the consent of whose Holders is required for any such amendment, supplemental indenture or waiver provided for in this Indenture; or (3) modify any of the waiver provisions, except to increase any required percentage or to provide that certain other provisions of this Indenture cannot be modified or waived without the consent of the Holder of each outstanding Note affected thereby; or (4) cause the Notes or any Guarantee to become subordinate in right of payment to any other Indebtedness. It shall not be necessary for the consent of the Holders under this Section 9.2 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof. After an amendment, supplement or waiver under this Section becomes effective, the Company shall mail to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any 92 defect therein, shall not, however, in any way impair or affect the validity of any such supplemental indenture or waiver. After an amendment, supplement or waiver under this Section 9.2 or under Section 9.4 hereof becomes effective, it shall bind each Holder. In connection with any amendment, supplement or waiver under this Article IX, the Company may, but shall not be obligated to, offer to any Holder who consents to such amendment, supplement or waiver, or to all Holders, consideration for such Holder's consent to such amendment, supplement or waiver. SECTION 9.3. COMPLIANCE WITH TIA Every amendment, waiver or supplement of this Indenture or the Notes shall comply with the TIA as then in effect. SECTION 9.4. REVOCATION AND EFFECT OF CONSENTS Until an amendment, waiver or supplement becomes effective, a consent to it by a Holder is a continuing consent by the Holder 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 or subsequent Holder may revoke the consent as to his Note or portion of his Note by written notice to the Company or the Person designated by the Company as the Person to whom consents should be sent if such revocation is received by the Company or such Person before the date on which the Trustee receives an Officers' Certificate certifying that the Holders of the requisite principal amount of Notes have consented (and not theretofore revoked such consent) to the amendment, supplement or waiver. The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver, which record date shall be the date so fixed by the Company notwithstanding the provisions of the TIA. If a record date is fixed, then notwithstanding the last sentence of the immediately preceding paragraph, those Persons who were Holders at such record date, and only those Persons (or their duly designated proxies), shall be entitled to revoke any consent previously given, whether or not such Persons continue to be Holders after such record date. After an amendment, supplement or waiver becomes effective, it shall bind every Securityholder, unless it makes a change described in any of clauses (1) through (3) of Section 9.2 hereof, in which case, the amendment, supplement or waiver shall bind only each Holder of a Note who has consented to it and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder's Note; provided, that any such waiver shall not impair or affect the right of any Holder to receive payment of principal and premium of and interest (and Liquidated Damages, if any) on a Note, on or after the respective dates set 93 for such amounts to become due and payable expressed in such Note, or to bring suit for the enforcement of any such payment on or after such respective dates. SECTION 9.5. NOTATION ON OR EXCHANGE OF NOTES If an amendment, supplement or waiver changes the terms of a Note, the Trustee may require the Holder of the Note to deliver it to the Trustee or require the Holder to put an appropriate notation on the Note. The Trustee may place an appropriate notation on the Note about the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Note shall issue and the Trustee shall authenticate a new Note that reflects the changed terms. Any failure to make the appropriate notation or to issue a new Note shall not affect the validity of such amendment, supplement or waiver. SECTION 9.6. TRUSTEE TO SIGN AMENDMENTS, ETC. The Trustee shall execute any amendment, supplement or waiver authorized pursuant to this Article IX; provided, that the Trustee may, but shall not be obligated to, execute any such amendment, supplement or waiver which affects the Trustee's own rights, duties or immunities under this Indenture. The Trustee shall be entitled to receive, and shall be fully protected in relying upon, an Opinion of Counsel stating that the execution of any amendment, supplement or waiver authorized pursuant to this Article IX is authorized or permitted by this Indenture. ARTICLE X RIGHT TO REQUIRE REPURCHASE SECTION 10.1. REPURCHASE OF NOTES AT THE OPTION OF THE HOLDER UPON A CHANGE OF CONTROL. (a) In the event that a Change of Control has occurred, each Holder of Notes will have the right, at such Holder's option, pursuant to an offer (subject only to conditions required by applicable law, if any) by the Company (the "Change of Control Offer"), to require the Company to repurchase all or any part of such Holder's Notes (provided, that the principal amount of such Notes must be $1,000 or an integral multiple thereof) on a date (the "Change of Control Purchase Date") that is no later than 60 days after the occurrence of such Change of Control, at a cash price equal to 101% of the principal amount thereof (the "Change of Control Purchase Price"), together with accrued and unpaid interest and Liquidated Damages, if any, to the Change of Control Purchase Date. Notwithstanding the foregoing, the Company will not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in 94 the manner, at the times and otherwise in compliance with the requirements set forth herein applicable to a Change of Control Offer made by the Company and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer. In addition, if the Convertible Note is outstanding on the date of a Change of Control that also constitutes a "Change of Control" as defined in the Convertible Note, the Change of Control notice delivered to Holders pursuant to this Indenture shall include a statement that the Company will prepay or redeem the Convertible Note upon the completion of the Change of Control Offer in accordance with clause (z) of Section 4.3. (b) In the event that, pursuant to this Section 10.1, the Company shall be required to commence a Change of Control Offer, the Company shall follow the procedures set forth in this Section 10.1 as follows: (1) the Change of Control Offer shall commence within 30 days following the occurrence of a Change of Control; (2) the Change of Control Offer shall remain open for 20 Business Days following its commencement (the "Change of Control Offer Period") or such other period as may be required by applicable law; (3) upon the expiration of the Change of Control Offer Period, the Company promptly shall purchase all of the properly tendered Notes at the Change of Control Purchase Price; (4) if the Change of Control Purchase Date is on or after an interest payment Record Date and on or before the associated Interest Payment Date, any accrued and unpaid interest (and Liquidated Damages, if any) due on such Interest Payment Date will be paid to the Person in whose name a Note is registered at the close of business on such Record Date on the corresponding Interest Payment Date; (5) the Company shall provide the Trustee and the Paying Agent with written notice of the Change of Control Offer at least three Business Days before the commencement of any Change of Control Offer; and (6) on or before the commencement of any Change of Control Offer, the Company or the Trustee (upon the request and at the expense of the Company) shall send, by first-class mail, a notice to each of the Securityholders, which (to the extent consistent with this Indenture) shall govern the terms of the Change of Control Offer and shall state: (A) that the Change of Control Offer is being made pursuant to this Section 10.1 and that all Notes, or portions thereof, tendered will be accepted for payment; 95 (B) the Change of Control Purchase Price (including the amount of accrued but unpaid interest (and Liquidated Damages, if any)) and the Change of Control Purchase Date; (C) that any Note, or portion thereof, not tendered or accepted for payment will continue to accrue interest (and Liquidated Damages, if any); (D) that, unless the Company defaults in depositing cash with the Paying Agent in accordance with the penultimate paragraph of this Section 10.1, or such payment is prevented for any reason, any Note, or portion thereof, accepted for payment pursuant to the Change of Control Offer shall cease to accrue interest (and Liquidated Damages, if any) after the Change of Control Purchase Date; (E) that Holders electing to have a Note, or portion thereof, purchased pursuant to a Change of Control Offer will 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 Paying Agent (which may not for purposes of this Section 10.1, notwithstanding anything in this Indenture to the contrary, be the Company or any Affiliate of the Company) at the address specified in the notice prior to the expiration of the Change of Control Offer; (F) that Holders will be entitled to withdraw their election, in whole or in part, if the Paying Agent receives, prior to the expiration of the Change of Control Offer, a facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Notes the Holder is withdrawing and a statement containing a facsimile signature and stating that such Holder is withdrawing his election to have such principal amount of Notes purchased; (G) that Holders whose Notes are purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered; and (H) a brief description of the events resulting in such Change of Control. On or before the Change of Control Purchase Date, the Company shall: 96 (1) accept for payment Notes or portions thereof properly tendered pursuant to the Change of Control Offer; (2) deposit with the Paying Agent an amount in cash sufficient to pay the Change of Control Purchase Price (together with accrued and unpaid interest and Liquidated Damages, if any) of all Notes so tendered; and (3) deliver to the Trustee the Notes so accepted together with an Officers' Certificate listing the Notes or portions thereof being purchased by the Company. The Paying Agent promptly shall pay the Holders of Notes so accepted an amount equal to the Change of Control Purchase Price (together with accrued and unpaid interest and Liquidated Damages, if any), and the Trustee promptly will authenticate and deliver to such Holders a new Note equal in principal amount to any unpurchased portion of the Note surrendered. Any Notes not so accepted will be delivered promptly by the Company to the Holder thereof. The Company publicly will announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Purchase Date. Any Change of Control Offer shall be made in compliance with all applicable laws, rules and regulations, including, if applicable, Regulation 14E under the Exchange Act and the rules thereunder and all other applicable Federal and state securities laws. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Article X, the Company's compliance or compliance by any of the Guarantors with such laws and regulations shall not in and of itself cause a breach of their obligations under this Article X. ARTICLE XI GUARANTEE SECTION 11.1. GUARANTEE (a) Each of the Guarantors shall, jointly and severally, irrevocably and unconditionally guarantee, on a senior basis (the "Guarantee"), to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability against the Company and any other Guarantors of this Indenture, the Notes or the obligations of the Company under this Indenture or the Notes, that: (x) the principal of and premium (if any), and interest (and Liquidated Damages, if any) on the Notes will be paid in full when due, whether at the Maturity Date or Interest Payment Date, by acceleration, call for redemption, upon a Change of Control Offer, upon an Asset Sale Offer or otherwise; (y) all other obligations of the Company to the Holders or the Trustee under this Indenture or the Notes will be promptly paid in full or performed, all in accordance with the terms of this Indenture and the Notes; and (z) in case of any extension of time of payment or 97 renewal of any Notes or any of such other obligations, the same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at maturity, by acceleration, call for redemption, upon a Change of Control Offer, upon an Asset Sale Offer or otherwise. Failing payment when due of any amount so guaranteed for whatever reason, each Guarantor shall be obligated to pay the same before failure so to pay becomes an Event of Default. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection. If the Company or a Guarantor defaults in the payment of the principal of, premium, if any, or interest (or Liquidated Damages, if any) on, the Notes when and as the same shall become due, whether upon maturity, acceleration, call for redemption, upon a Change of Control Offer, upon an Asset Sale Offer or otherwise, without the necessity of action by the Trustee or any Holder, each Guarantor shall be required, jointly and severally, to promptly make such payment in full. The Company shall cause each Subsidiary that is formed or acquired after the date hereof and each subsidiary that becomes a Subsidiary after the date hereof, in each case other than Foreign Subsidiaries, concurrently upon becoming a Subsidiary, to become a Guarantor hereunder and execute and deliver to the Trustee a supplemental indenture as provided pursuant to the terms of this Indenture. Notwithstanding anything herein to the contrary, if any of the Company's Subsidiaries (including Foreign Subsidiaries) that is not a Guarantor guarantees any of the Company's other Indebtedness or any other Indebtedness of any of its Subsidiaries, or the Company or any of its Subsidiaries, individually or collectively, pledges more than 65% of the Voting Equity Interests of such Subsidiary to a United States lender to secure Indebtedness of the Company or Indebtedness of any Guarantor, then such Subsidiary must become a Guarantor in accordance with the terms hereof. (b) Each Guarantor hereby agrees to the fullest extent permitted by applicable law, that its obligations with regard to this Guarantee shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any delays in obtaining or realizing upon or failures to obtain or realize upon collateral, the recovery of any judgment against the Company, any action to enforce the same or any other circumstances that might otherwise constitute a legal or equitable discharge or defense of a Guarantor. Each Guarantor hereby waives, to the fullest extent permitted by applicable law, diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company or right to require the prior disposition of the assets of the Company to meet its obligations, protest, notice and all demands whatsoever and covenants that this Guarantee will not be discharged except by complete performance of the obligations contained in the Notes and this Indenture. 98 (c) If any Holder or the Trustee is required by any court or otherwise to return to either the Company or any Guarantor, or any Custodian or similar official acting in relation to either the Company or such Guarantor, any amount paid by either the Company or such Guarantor to the Trustee or such Holder, this Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. Each 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 Guarantor further agrees that, as between such 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 6.2 hereof for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration as to the Company of the obligations guaranteed hereby, and (ii) in the event of any declaration of acceleration of those obligations as provided in Section 6.2 hereof, those obligations (whether or not due and payable) will forthwith become due and payable by each of the Guarantors for the purpose of this Guarantee. (d) It is the intention of each Guarantor and the Company that the obligations of each Guarantor hereunder shall be in, but not in excess of, the maximum amount permitted by applicable law. Accordingly, if the obligations in respect of the Guarantee would be annulled, avoided or subordinated to the creditors of any Guarantor by a court of competent jurisdiction in a proceeding actually pending before such court as a result of a determination both that such Guarantee was made by such Guarantor without fair consideration and, immediately after giving effect thereto, such Guarantor was insolvent or unable to pay its debts as they mature or left with an unreasonably small capital, then the obligations of such Guarantor under such Guarantee shall be reduced by such court if and to the extent such reduction would result in the avoidance of such annulment, avoidance or subordination; provided, however, that any reduction pursuant to this paragraph shall be made in the smallest amount as is strictly necessary to reach such result. For purposes of this paragraph, "fair consideration", "insolvency", "unable to pay its debts as they mature", "unreasonably small capital" and the effective times of reductions, if any, required by this paragraph shall be determined in accordance with applicable law. SECTION 11.2. EXECUTION AND DELIVERY OF GUARANTEE Each Guarantor shall, by virtue of such Guarantor's execution and delivery of an indenture supplement pursuant to Section 11.1 hereof, be deemed to have signed on each Note issued hereunder the notation of guarantee set forth on the form of the Notes attached hereto as Exhibit A to the same extent as if the signature of such Guarantor appeared on such Note. The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the guarantee set forth in Section 11.1 on behalf of each Guarantor. The notation of a guarantee set forth on any Note shall be null and void and of no further effect with respect to the guarantee of any Guarantor which, pursuant to Section 11.4, is released from such Guarantee. 99 SECTION 11.3. CERTAIN BANKRUPTCY EVENTS Each Guarantor hereby covenants and agrees, to the fullest extent that it may do so under applicable law, that in the event of the insolvency, bankruptcy, dissolution, liquidation or reorganization of the Company, such Guarantor shall not file (or join in any filing of), or otherwise seek to participate in the filing of, any motion or request seeking to stay or to prohibit (even temporarily) execution on the Guarantee and hereby waives and agrees not to take the benefit of any such stay of execution, whether under Section 362 or 105 of the United States Bankruptcy Code or otherwise. SECTION 11.4. LIMITATION ON MERGER OF SUBSIDIARIES AND RELEASE OF GUARANTORS No Guarantor shall consolidate or merge with or into (whether or not such Guarantor is the surviving Person) another Person unless, subject to the provisions of the following paragraph and the other provisions of this Indenture, (1) the Person formed by or surviving any such consolidation or merger (if other than such Guarantor) assumes all the obligations of such Guarantor pursuant to a supplemental indenture in form reasonably satisfactory to the Trustee, pursuant to which such Person shall unconditionally guarantee, on a senior basis, all of such Guarantor's obligations under such Guarantor's Guarantee on the terms set forth herein; (2) immediately before and immediately after giving effect to such transaction on a pro forma basis, no Default or Event of Default shall have occurred or be continuing; and (3) immediately after giving effect to such transaction on a pro forma basis, the Company could incur at least $1.00 of additional Indebtedness pursuant to the Debt Incurrence Ratio set forth in Section 4.11. The provisions of this Section 11.4 shall not apply to the merger of any Guarantors with and into each other or with or into the Company. Upon the sale or disposition (whether by merger, stock purchase, Asset Sale or otherwise) of a Guarantor (as an entirety) to an entity which is not, and is not required to become, a Guarantor, or the designation of a Subsidiary to become an Unrestricted Subsidiary, which transaction is otherwise in compliance with this Indenture (including, without limitation, the provisions of Section 4.14), such Guarantor will be deemed released from its obligations under its Guarantee of the Notes; provided, however, that any such release shall occur only to the extent that all obligations of such Guarantor under all of its guarantees of, and under all of its pledges of assets or other security interests that secure, any of the Company's Indebtedness or any Indebtedness of any other of the Company's Subsidiaries shall also terminate upon such release, sale or transfer and none of its Equity Interests are pledged for the benefit of any holder of any of the Company's Indebtedness or any Indebtedness of any of the Company's Subsidiaries. 100 ARTICLE XII MISCELLANEOUS SECTION 12.1.

Such payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. 3. Paying Agent and Registrar. Initially, U.S. Bank, N.A., the Trustee under the Indenture, will act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity. 4. Indenture. The Company issued the Notes under an Indenture dated as of December 12, 2001 ("Indenture") among the Company, the Guarantors party thereto and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code Sections 77aaa-77bbbb). The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. 5. Optional Redemption. (a) Except as set forth in clause (b) of this Section, the Company shall not have the option to redeem the Notes pursuant to this Section prior to December 15, 2005. The Notes will be redeemable for cash at the option of the Company, in whole or in part, at any time on or after December 15, 2005, upon not less than 30 days nor more than 60 days prior notice mailed by first class mail to each Holder at its last registered address, at the following redemption prices (expressed as percentages of the principal amount) if redeemed during the 12-month period commencing December 15 of the years indicated below, in each case (subject to the right of Holders of record on a Record Date to receive the corresponding interest due (and the corresponding Liquidated Damages, if any) on the corresponding Interest Payment Date that is on or prior to such Redemption Date), together with accrued and unpaid interest and Liquidated Damages, if any, thereon to the Redemption Date: <Table> <Caption> YEAR PERCENTAGE ---- ---------- 2005.............................................................105.250% 2006.............................................................102.625% 2007 and thereafter..............................................100.000% </Table> (b) Notwithstanding the provisions of clause (a) of this Section, at any time or from time to time on or prior to December 15, 2004, upon any Public Equity A-7 Offering, up to 35% of the aggregate principal amount of the Notes issued pursuant to the Indenture may be redeemed at the option of the Company within 90 days of such Public Equity Offering, on not less than 30 days, but not more than 60 days, notice to each Holder of the Notes to be redeemed, with cash from the Net Cash Proceeds of such Public Equity Offering, at a redemption price equal to 110.500% of the principal amount thereof (subject to the right of Holders of record on a Record Date to receive the corresponding interest (and the corresponding Liquidated Damages, if any) due on the Interest Payment Date that is on or prior to such Redemption Date), together with accrued and unpaid interest and Liquidated Damages, if any, thereon to the Redemption Date; provided, however, that immediately following such redemption not less than 65% of the aggregate principal amount of the Notes originally issued pursuant to the Indenture on the Issue Date remain outstanding. (c) Notice of redemption will be mailed by first class mail at least 30 days but not more than 60 days before the Redemption Date to each Holder whose Notes are to be redeemed at its registered address. Notes in denominations larger than $1,000 may be redeemed in part but only in integral multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed. On and after the Redemption Date, interest (and Liquidated Damages, if any) ceases to accrue on Notes or portions thereof called for redemption unless the Company defaults in such payments due on the Redemption Date. 6. Mandatory Redemption. The Company shall not be required to make mandatory redemption payments with respect to the Notes. The Notes shall not have the benefit of any sinking fund. 7. Offers to Purchase. (a) Change of Control. In the event that a Change of Control has occurred, each Holder of Notes will have the right, at such Holder's option, pursuant to an offer (subject only to conditions required by applicable law, if any) by the Company (the "Change of Control Offer"), to require the Company to repurchase all or any part of such Holder's Notes (provided, that the principal amount of such Notes must be $1,000 or an integral multiple thereof) on a date (the "Change of Control Purchase Date") that is no later than 60 days after the occurrence of such Change of Control, at a cash price equal to 101% of the principal amount thereof (the "Change of Control Purchase Price"), together with accrued and unpaid interest and Liquidated Damages, if any, to the Change of Control Purchase Date. The Change of Control Offer shall be made within 30 days following a Change of Control and shall remain open for 20 Business Days following its commencement (the "Change of Control Offer Period") or such other period as may be required by applicable law. Upon expiration of the Change of Control Offer Period, the Company promptly shall purchase all Notes properly tendered in response to the Change of Control Offer. On or before the Change of Control Purchase Date, the Company shall (i) accept for payment Notes or portions thereof properly tendered and not validly withdrawn pursuant to the Change of Control Offer, (ii) deposit with the Paying Agent A-8 an amount in cash sufficient to pay the Change of Control Purchase Price (together with accrued and unpaid interest and Liquidated Damages, if any) of all Notes so tendered and (iii) deliver to the Trustee the Notes so accepted together with an Officers' Certificate listing the Notes or portions thereof being purchased by the Company. The Paying Agent promptly shall pay the Holders of Notes so accepted an amount equal to the Change of Control Purchase Price (together with accrued and unpaid interest and Liquidated Damages, if any) and the Trustee promptly shall authenticate and deliver to such Holders a new Note equal in principal amount to any unpurchased portion of the Note surrendered. Any Notes not so accepted will be delivered promptly by the Company to the Holder thereof. The Company publicly will announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Purchase Date. (b) Asset Sale. Except as otherwise set forth in Section 4.14 of the Indenture, the Company and the Guarantors shall not, and neither the Company nor the Guarantors shall permit any of their respective Subsidiaries to, in one or a series of related transactions, convey, sell, transfer, assign or otherwise dispose of, directly or indirectly, any of their property, business or assets, including by merger or consolidation (in the case of a Guarantor or a Subsidiary of the Company), and including any sale or other transfer or issuance of any Equity Interests of any Subsidiary of the Company, whether by the Company or one of its Subsidiaries or through the issuance, sale or transfer of Equity Interests by a Subsidiary of the Company, and including any sale and leaseback transaction (any of the foregoing, an "Asset Sale"), unless: (1) at least 75% of the total consideration for such Asset Sale or series of related Asset Sales consists of cash or Cash Equivalents; and (2) the Company receives or such Subsidiary receives, as applicable, fair market value for such Asset Sale, such determination to be made in good faith by the Company's Board of Directors for Asset Sales exceeding $2,000,000. Solely for purposes of (1) above, (a) any Indebtedness (other than Subordinated Indebtedness) of the Company or such Subsidiary that is expressly assumed by the transferee in such Asset Sale and with respect to which the Company is and its Subsidiaries are fully and unconditionally released from any and all obligations in connection therewith, (b) property that within 30 days of such Asset Sale is converted into cash or Cash Equivalents; provided, that such cash and Cash Equivalents shall be treated as Net Cash Proceeds attributable to the original Asset Sale for which such property was received, and (c) the fair market value, as determined in good faith by the Board of Directors, of any asset (other than securities) received by the Company or any Subsidiary that, in the good faith reasonable judgment of the Company's Board of Directors, will immediately constitute or be a part of a Related Business shall be deemed to be cash or Cash Equivalents. Within 360 days following such Asset Sale, the Net Cash Proceeds therefrom are: (a) invested in fixed assets and property (other than notes, bonds, obligations and other securities, except in connection with the acquisition of a Guarantor in a Related Business) that in the good faith reasonable judgment of the Company's Board of Directors will immediately constitute or be a part of a Related Business of the Company or such Subsidiary (if it continues to be a Subsidiary) immediately following such transaction; or (b) used to retire Purchase Money Indebtedness secured by the asset that was the subject of the Asset Sale or to A-9 permanently reduce the amount of Indebtedness outstanding under the Credit Agreement; or (c) applied to the optional redemption of the Notes in accordance with the terms of the Indenture and the Company's other Indebtedness ranking on a parity with the Notes and with similar provisions requiring the Company to redeem such Indebtedness with the proceeds from such Asset Sale, pro rata in proportion to the respective principal amounts (or accreted values in the case of Indebtedness issued with an original issue discount) of the Notes and such other Indebtedness then outstanding. Pending the final application of any Net Cash Proceeds, the Company may temporarily reduce revolving credit borrowings or otherwise invest the Net Cash Proceeds in any manner that is not prohibited by the Indenture. The accumulated Net Cash Proceeds from Asset Sales not applied as set forth in (a), (b) or (c) of the preceding paragraph shall constitute "Excess Proceeds". Within 30 days after the date that the amount of Excess Proceeds exceeds $10,000,000, the Company shall apply the Excess Proceeds (the "Asset Sale Offer Amount") to the repurchase of the Notes and such other Indebtedness ranking on a parity with the Notes and with similar provisions requiring the Company to make an offer to purchase such Indebtedness with the proceeds from such Asset Sale pursuant to a cash offer (subject only to conditions required by applicable law, if any) (pro rata in proportion to the respective principal amounts (or accreted values in the case of Indebtedness issued with an original issue discount) of the Notes and such other Indebtedness then outstanding) (the "Asset Sale Offer") at a purchase price of 100% of the principal amount (or accreted value in the case of Indebtedness issued with an original issue discount) (the "Asset Sale Offer Price") together with accrued and unpaid interest and Liquidated Damages, if any, to the date of payment. Each Asset Sale Offer shall remain open for 20 Business Days following its commencement (the "Asset Sale Offer Period"). Upon expiration of the Asset Sale Offer Period, the Company shall apply the Asset Sale Offer Amount plus an amount equal to accrued and unpaid interest and Liquidated Damages, if any, to the purchase of all Indebtedness properly tendered in accordance with the provisions hereof (on a pro rata basis if the Asset Sale Offer Amount is insufficient to purchase all Indebtedness so tendered) at the Asset Sale Offer Price (together with accrued interest and Liquidated Damages, if any). To the extent that the aggregate amount of Notes and such other pari passu Indebtedness tendered pursuant to an Asset Sale Offer is less than the Asset Sale Offer Amount, the Company may use any remaining Net Cash Proceeds as otherwise permitted by the Indenture (other than for making Restricted Payments that are not Investments) and following the consummation of each Asset Sale Offer the Excess Proceeds amount shall be reset to zero. 8. Denominations, Transfer, Exchange. The Notes are in registered form without coupons in denominations of $1,000 and integral multiples of $1,000. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Company need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed A-10 in part. Also, it need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed or during the period between a Record Date and the corresponding Interest Payment Date. 9. Persons Deemed Owners. The registered Holder of a Note may be treated as its owner for all purposes. 10. Amendment, Supplement and Waiver. Subject to certain exceptions, the Indenture, the Notes or the Guarantees may be amended or supplemented with the consent of the Holders of not less than a majority in aggregate principal amount of the then outstanding Notes, and any existing Default or compliance with any provision of the Indenture, the Notes or the Guarantees may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes. Without the consent of any Holder of a Note, the Indenture, the Notes or the Guarantees may be amended or supplemented (a) to cure any ambiguity, defect or inconsistency, (b) to add to the covenants of the Company or the Guarantors for the benefit of the Holders, or to surrender any right or power conferred upon the Company or the Guarantors by the Indenture or herein; (c) to provide for collateral for or additional Guarantors of the Notes; (d) to evidence the succession of another Person to the Company, and the assumption by any such successor of the obligations of the Company, herein and in the Indenture in accordance with the terms of the Indenture; (e) to comply with the TIA; (f) to evidence the succession of another corporation to any Guarantor and assumption by any such successor of the Guarantee of such Guarantor pursuant to the Indenture; (g) to evidence the release of any Guarantor; (h) to evidence and provide for the acceptance of appointment of a successor Trustee with respect to the Notes; (i) in any other case where a supplemental indenture is required or permitted to be entered into pursuant to the provisions of the Indenture without the consent of any Holder; (j) to provide for the issuance and authorization of the Exchange Notes; or (k) to make any change that does not adversely affect the rights of any Holder. 11.

Trustee Dealings with 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. A-12 13. No Recourse Against Others. No direct or indirect incorporator, stockholder, employee, officer or director, as such, past, present or future, of the Company or any Guarantor, or any successor entity, shall have any personal liability in respect of the obligations of the Company or the Guarantors under the Notes or the Indenture solely by reason of his or its status as such incorporator, stockholder, employee, officer or director; provided, that this Section 13 shall in no way limit the obligation of any Guarantor pursuant to any Guarantee of the Notes.

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, and any such redemption shall not be affected by any defect in or omission of such numbers. 18.

Capitalized terms used but not defined herein shall have the meanings given to them in the Indenture. In connection with our proposed purchase of $____________ aggregate principal amount of: (a) a beneficial interest in a Global Note, or (b) a Definitive Note, we confirm that: 1.

We are an institutional "accredited investor" under the Securities Act within the meaning of subparagraph (a)(1), (2), (3) or (7) of Rule 501 under the Securities Act D-1 ("Rule 501") or, if the Notes are to be purchased for one or more accounts ("investor accounts") for which we are acting as fiduciary or agent, each such investor account is an institutional "accredited investor" on a like basis. We have such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of purchasing the Notes and invest in or purchase securities similar to the Notes in the normal course of our business. We and any accounts for which we are acting are each aware that we may be required, and are each able, to bear the economic risk of our or its investment in the Notes for an indefinite period of time. 3.

The foregoing restrictions on resale will not apply subsequent to the Resale Restriction Termination Date. If any resale or other transfer of the Notes is proposed to be made pursuant to clause (e) above prior to the Resale Restriction Termination Date, the transferor shall deliver a letter from the transferee substantially in the form of this letter to the Company and the Trustee, which shall provide, among other things, that the transferee is an institutional "accredited investor" within the meaning of subparagraph (a)(1), (2), (3) or (7) of Rule 501 and that it is acquiring such Notes for investment purposes and not for distribution in violation of the Securities Act. Each purchaser acknowledges that the Company and the Trustee reserve the right prior to the offer, sale or other transfer made prior to the Resale Termination Date to require the delivery of an opinion of counsel, certifications and/or other information satisfactory to the Company and the Trustee. We further understand that any subsequent transfer by us of the Notes or beneficial interests in therein acquired by us must be effected through one of the Initial Purchasers. 5.
