The Company and the Trustee may charge for their expenses in replacing a Note.

Every replacement Note issued in accordance with this Section 2.08 is an additional obligation of the Company and any other obligor upon the Notes and shall be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder.

The Company and the Trustee may charge the Holder for their expenses in replacing a Note.

Except as set forth in Section 2.10 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 2.08 hereof, it ceases to be outstanding unless the Company and the Trustee receive proof satisfactory to it that the replaced Note is held by a bona fide purchaser.

If the Paying Agent segregates and holds in trust, in accordance with this Indenture, by 11:00 a.m. New York City time, on a redemption date or other maturity date money sufficient to pay all principal, premium and Additional Interest, if any, and interest payable on that date with respect to the Notes (or portions thereof) to be redeemed or maturing, as the case may be, then on and after that date such Notes (or portions thereof) cease to be outstanding and interest on them ceases to accrue.

SECTION 2.10. 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 deemed not to be 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 Responsible Officer of the Trustee actually knows are so owned shall be so disregarded.

SECTION 2.11. Temporary Notes

In the event that Definitive Notes are to be issued under the terms of this Indenture, until such Definitive Notes are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Notes. Temporary Notes shall be substantially in the form, and shall carry all rights, of

Definitive Notes but may have variations that the Company considers appropriate for temporary Notes. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate Definitive Notes. After the preparation of Definitive Notes, the temporary Notes shall be exchangeable for Definitive Notes upon surrender of the temporary Notes at any office or agency maintained by the Company for that purpose and such exchange shall be without charge to the Holder. Upon surrender for cancellation of any one or more temporary Notes, the Company shall execute, and the Trustee shall authenticate and make available for delivery in exchange therefor, one or more Definitive Notes representing an equal principal amount of Notes. Until so exchanged, the Holder of temporary Notes shall in all respects be entitled to the same benefits under this Indenture as a Holder of Definitive Notes.

SECTION 2.12. Cancellation

The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel and destroy all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation in accordance with customary practices (subject to the record retention requirement of the Exchange Act) and, upon request, deliver a certificate of such destruction to the Company unless the Company directs the Trustee to deliver canceled 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 2.13. Defaulted Interest

If the Company defaults in a payment of interest on the Notes, it shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate and in the manner provided in the Notes and in Sections 2.14 and 4.01 hereof. The Company shall notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Company shall fix or cause to be fixed each such special record date and payment date; provided that no such special record date shall be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Company (or, upon the written request of the Company, the Trustee in the name and at the expense of the Company) shall mail or cause to be mailed to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid.

SECTION 2.14. Computation and Payment of Interest

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

(c) Any Additional PIK Notes shall, after being executed and authenticated pursuant to Section 2.03 hereof, be (i) mailed to the person entitled thereto as shown on the register for the Definitive Notes as of the relevant Record Date or (ii) deposited into the account specified by the Holder or Holders thereof as of the relevant Record Date if the Notes are held in global form. Alternatively, the Company may direct the Paying Agent to make the appropriate amendments to the schedule of principal amounts of the relevant Global Notes outstanding and arrange for deposit into the account specified by the Holder or Holders thereof as of the relevant Record Date. Payment shall be made in such form and upon such terms as specified herein and the Company shall and Paying Agent may take additional steps as is necessary to effect such payment.

(d) With respect to any Additional PIK Notes issued after the Issue Date (except for Notes authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Notes pursuant to Sections 2.07, 2.08, 2.09, 2.11 and 3.06), the aggregate principal amount of such Additional PIK Notes which may be authenticated and delivered under this Indenture shall be (i) established in or pursuant to a Board Resolution of the Company (provided that any such Board Resolution may authorize authentication of up to a maximum aggregate principal amount from time to time without referring to aggregate principal amounts for specific interest periods) and (ii) set forth or determined in an Officers' Certificate of the Company.

In the event of partial redemption by lot, the particular Notes to be redeemed shall be selected, unless otherwise provided herein, not less than 30 nor more than 60 days prior to the redemption date by the Trustee from the outstanding Notes not previously called for redemption.

Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption.

SECTION 3.03. Notice of Redemption

At least 30 days but not more than 60 days before a redemption date, the Company shall mail or cause to be mailed, by first class mail, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days

The notice shall identify the Notes to be redeemed and shall state:

(a) the redemption date;

(b) the redemption price;

(h) that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes.

At the Company's request, the Trustee shall give the notice of redemption in the Company's name and at its expense; provided that the Company shall have delivered to the Trustee, at least 35 days prior to the redemption date (unless a shorter period is acceptable to the Trustee), an Officers' Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph.

If the Company complies with the provisions of the preceding paragraph, on and after the redemption date, interest shall cease to accrue on the Notes or the portions of Notes called for redemption. If a Note is redeemed on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption shall not be so paid upon surrender for redemption because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption date until such principal is paid, and to the extent lawful on any interest not paid on such

unpaid principal, in each case at the rate and in the manner provided in the Notes and in Sections 2.14 and 4.01 hereof.

The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, "incur") any Indebtedness (including Acquired Debt), and the Company shall not issue any Disqualified Stock and shall not permit any of its Restricted Subsidiaries to issue any shares of preferred stock; provided, however, that (i) the Company may incur Indebtedness (including Acquired Debt) and the Company may issue Disqualified Stock if the Fixed Charge Coverage Ratio for the Company's most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock is issued would have been at least 2.0 to 1.0, and (ii) K&F Industries and any of its Domestic Subsidiaries may incur Indebtedness (including Acquired Debt) and K&F Industries and any of its Domestic Subsidiaries may issue Disqualified Stock if the Fixed Charge Coverage Ratio for K&F Industries' most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock is issued would have been at least 2.0 to 1.0, in each case determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or Disqualified Stock had been issued, as the case may be, at the beginning of such four-quarter period.

The first paragraph of this covenant shall not prohibit:

(1) the incurrence by the Company or any Restricted Subsidiary of additional Indebtedness and letters of credit under one or more Credit Facilities in an aggregate principal amount at any one time outstanding under this clause (1) (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of the Company and its Restricted Subsidiaries thereunder) not to exceed $530.0 million, less the sum of all principal payments with respect to such Indebtedness pursuant to clause (A) of Section 4.10;

(2) the incurrence by the Company and its Restricted Subsidiaries of the Existing Indebtedness;

(3) the incurrence by the Company of Indebtedness represented by the Notes (including any Additional PIK Notes but excluding any Additional Notes);

(4) (A) Indebtedness incurred to finance the purchase, improvement or construction of property, plant or equipment (including through the purchase of all of the Capital Stock of a Person) so long as such Indebtedness is secured by a Lien on the property, plant or equipment so purchased, improved or constructed and such Indebtedness does not exceed the value of such property, plant or equipment so purchased or constructed or the value of such improvements and such Lien shall not extend to or cover other assets of the Company or any of its Restricted Subsidiaries other than the property, plant or equipment so purchased, improved or constructed and the real property, if any, on which the property so constructed, improved or purchased, is situated and the accessions, attachments, replacements and improvements thereto or (B) Indebtedness incurred in connection with any lease financing transaction in conjunction with the acquisition of new property or improvements to existing property; provided that such lease financing transaction is consummated within 90 days of such acquisition or completion of such improvements and the aggregate of the Indebtedness incurred pursuant to clauses (A) and (B) does not exceed $15.0 million during any fiscal year (such amount is referred to as the "Maximum Amount"); provided that the Maximum Amount for each year shall be increased by the excess, if any, of (a) $30.0 million over (b) the amount of expenditures made in reliance on the provisions of this clause (4) for the immediately preceding two years;

(5) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness (other than intercompany Indebtedness) in exchange for, or the net proceeds of which are used to redeem, repurchase, retire, defease, or otherwise refund, refinance, or replace Indebtedness

that was permitted by this Indenture to be incurred under the first paragraph of this covenant or clauses (2), (3), (4), (5) or (6) of this paragraph;

(6) the incurrence by the Company of Senior Preferred Redemption Debt;

(7) the incurrence by the Company or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries; provided, however, that:

(a) if the Company is the obligor on such Indebtedness, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations with respect to the Notes; and

(b) (i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary of the Company, (ii) any sale or other transfer of any such Indebtedness to a Person that is neither the Company nor a Restricted Subsidiary of the Company or (iii) the designation of a Restricted Subsidiary that holds such Indebtedness as an Unrestricted Subsidiary, will be deemed, in each case, to constitute an incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (7);

(8) the incurrence by the Company or any of its Restricted Subsidiaries of Hedging Obligations;

(9) the guarantee by the Company or any of its Restricted Subsidiaries of Indebtedness of the Company or any of its Restricted Subsidiaries that was permitted to be incurred by another provision of this Section 4.09;

(10) obligations incurred in the ordinary course of business under (a) bankers acceptances or trade letters of credit which are to be repaid in full not more than one year after the date on which such Indebtedness is originally incurred to finance the purchase of goods by the Company or a Restricted Subsidiary of the Company; (b) standby letters of credit issued for the purpose of supporting (i) workers' compensation liabilities of the Company or any of its Restricted Subsidiaries as required by law, (ii) obligations with respect to leases of the Company or any of its Restricted Subsidiaries, or (iii) performance, payment, deposit or surety obligations of the Company or any of its Restricted Subsidiaries; (c) performance bonds and surety bonds, and refinancings thereof; and (d) guarantees of Indebtedness incurred in the ordinary course of business of suppliers, licensees, franchisees, or customers in an aggregate amount not to exceed $5.0 million at any time outstanding;

(11) Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument drawn against insufficient funds in the ordinary course of business, provided, however, that such Indebtedness is extinguished within five business days of the Company or its applicable Restricted Subsidiary being advised of such incurrence;

(12) Indebtedness under guarantees in respect of obligations of joint ventures of the Company or any of its Restricted Subsidiaries in aggregate principal amount not to exceed $20.0 million at any one time;

(13) Indebtedness incurred in connection with any sale and leaseback transaction; provided that the aggregate of the Indebtedness incurred pursuant to this clause (13) shall not exceed $30.0 million at any time outstanding;

(14) Indebtedness to repurchase shares, or cancel options to purchase shares, of Equity Interests of the Company or any Restricted Subsidiary of the Company or any direct or indirect parent of the Company held by any then current or former director, officer or employee of, or consultant to, the Company or any of its Restricted Subsidiaries; provided that the aggregate of the Indebtedness incurred pursuant to this clause (14) shall not exceed $5.0 million in any fiscal year; provided that the amount

available in any given fiscal year shall be increased by the excess, if any, of (i) $5.0 million over (ii) the amount used pursuant to this clause (14) in the immediately preceding two fiscal years;

(15) Indebtedness arising from any agreement providing for indemnities, guarantees, purchase price adjustments, holdbacks, contingency payment obligations based on the performance of the acquired or disposed assets or similar obligations (other than guarantees of Indebtedness) incurred by any Person in connection with the acquisition or disposition of assets;

(16) the incurrence by the Company or any of its Restricted Subsidiaries of Acquired Debt related to the acquisition of a Permitted Business if the Fixed Charge Coverage Ratio for the Company's most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date of such incurrence of Acquired Debt (the "Relevant Fixed Charge Coverage Ratio") determined immediately after giving effect to such incurrence and the related acquisition (including through a merger, consolidation or otherwise) is higher than the Relevant Fixed Charge Coverage Ratio determined immediately before giving effect to such incurrence and the related acquisition;

(17) the issuance of any preferred stock by a Restricted Subsidiary of the Company to the Company or to any other wholly-owned Restricted Subsidiary of the Company; and

(18) the incurrence by the Company or any of its Restricted Subsidiaries of additional Indebtedness or the issuance of Disqualified Stock or preferred stock of Restricted Subsidiaries in an aggregate principal amount (or accreted value, as applicable) at any time outstanding not to exceed $25.0 million.

The Company will not incur any Indebtedness under the preceding paragraph if the proceeds thereof are used, directly or indirectly, to refinance any Obligations of the Company subordinated to the Notes unless such Indebtedness will be subordinated to the Notes to at least the same extent as such subordinated Obligations.

If any Non-Recourse Debt of an Unrestricted Subsidiary shall at any time cease to constitute Non-Recourse Debt or such Unrestricted Subsidiary shall be redesignated a Restricted Subsidiary, such event will be deemed to constitute an incurrence of Indebtedness by a Restricted Subsidiary.

For purposes of determining compliance with this Section 4.09:

(1) in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories described in clauses (1) through (18) above, or is entitled to be incurred pursuant to the first paragraph of this Section 4.09, the Company will be permitted to classify (or later classify or reclassify in whole or in part in its sole discretion) such item of Indebtedness in any manner that complies with this Section 4.09;

(2) the accrual of interest, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same, or less onerous, terms, the payment of dividends on Disqualified Stock in the form of additional shares of the same class of Disqualified Stock, the accrual of dividends on Disqualified Stock and the accretion of the liquidation preference of Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock for purposes of this covenant; provided, in each such case (except for Specified PIK Interest), that the amount thereof is included in the Fixed Charges of the Company; and

(3) for the purposes of determining compliance with any dollar-denominated restriction on the incurrence of Indebtedness denominated in a foreign currency, the dollar-equivalent principal amount of such Indebtedness incurred pursuant thereto shall be calculated based on the relevant currency exchange rate in effect on the earlier of the date that such Indebtedness was incurred or the date that the Company or its applicable Restricted Subsidiary committed to incur such Indebtedness.

SECTION 4.10. Asset Sales

The Company shall not, and shall not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless:

(1) the Company (or the Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal to the fair market value of the assets or Equity Interests issued or sold or otherwise disposed of (such fair market value to be determined on the date of contractually agreeing to such Asset Sale);

(2) the fair market value is determined (a) by an executive officer of the Company if the value is less than $10.0 million or (b) in all other cases, by a resolution of the Company's Board of Directors, in either such case, as set forth in an Officers' Certificate delivered to the Trustee; and

(3) at least 75% of the consideration received in the Asset Sale by the Company or such Restricted Subsidiary is in the form of cash or Cash Equivalents. For purposes of this clause (3), each of the following shall be deemed to be cash:

(a) the amount of any liabilities, as shown on the Company's or such Restricted Subsidiary's most recent balance sheet or in the notes thereto, of the Company or such Restricted Subsidiary (other than liabilities of the Company that are by their terms subordinated to the Notes and contingent liabilities of the Company or any of its Restricted Subsidiaries) that are assumed by the transferee of any such assets; and

(b) any securities, notes or other obligations received by the Company or any such Restricted Subsidiary from such transferee that are substantially concurrently, subject to normal settlement periods, converted by the Company or such Restricted Subsidiary into cash or Cash Equivalents (to the extent of the cash or Cash Equivalents received in that conversion); and

(c) property received as consideration for such Asset Sale that would otherwise constitute a permitted application of Net Proceeds (or other cash in such amount) under clauses (B) or (D) under the next succeeding paragraph below.

Within 390 days (or, if the Senior Preferred Stock is outstanding, 325 days) after the receipt of any Net Proceeds from an Asset Sale, the Company or any of its Restricted Subsidiaries may apply an amount of cash equal to the amount of those Net Proceeds at its option to:

(A) reduce or repurchase Indebtedness of (i) the Company that is pari passu in right of payment with the Notes (provided that if the Company shall so reduce Obligations pari passu in right of payment with the Notes, the Company will offer to equally and ratably reduce Obligations under the Notes by making an offer (in accordance with the procedures set forth below for an Asset Sale Offer) to all Holders to purchase at a purchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest and Additional Interest, if any, the pro rata principal amount of the Notes) or (ii) any Restricted Subsidiary of the Company; and, if the Indebtedness repaid is revolving credit Indebtedness, to correspondingly reduce commitments with respect thereto;

(B) acquire (including by way of merger or consolidation) all or substantially all of the assets of, or a majority of the Voting Stock of, another Permitted Business;

(D) acquire other long-term assets that are used or useful in a Permitted Business.

Pending the final application of any Net Proceeds, the Company or any of its Restricted Subsidiaries may temporarily reduce revolving credit borrowings or otherwise invest the Net Proceeds in any manner that is not prohibited by this Indenture.

To the extent that the Company and its Restricted Subsidiaries do not apply an amount of cash equal to the amount of such Net Proceeds from Asset Sales during such period as provided in the second preceding paragraph the amount not so applied shall constitute "Excess Proceeds." No later than the 395^th day (or, if the Senior Preferred Stock is outstanding, the 330^th day) after the Asset Sale (or, at the Company's option, an earlier date), if the aggregate amount of Excess Proceeds exceeds $10.0 million, the Company shall make an offer (an "Asset Sale Offer") to all Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets to purchase the maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds (the "Offer Amount"). The offer price in any Asset Sale Offer will be equal to 100% of the principal amount (or accreted value, as applicable) of the Notes and such other pari passu Indebtedness, plus accrued and unpaid interest and Additional Interest (or its equivalent with respect to any such pari passu Indebtedness), if any, to the date of purchase, and will be payable in cash, in each case, in a minimum of $1,000 aggregate principal amount and integral multiples of $1.00 in excess thereof. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Notes and other pari passu Indebtedness tendered in such Asset Sale Offer exceeds the amount of Excess Proceeds, the Excess Proceeds will be allocated by the Company to the Notes and such other pari passu Indebtedness on a pro rata basis (based upon the respective principal amounts (or accreted value, if applicable) of the Notes and such other pari passu Indebtedness tendered into such Asset Sale Offer) and the portion of each Note to be purchased will thereafter be determined by the Trustee on a pro rata basis among the Holders of such Notes with appropriate adjustments such that the Notes may only be purchased in a minimum of $1,000 aggregate principal amount and integral multiples of $1.00 in excess thereof. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

Upon the commencement of an Asset Sale Offer, the Company shall send, by first class mail, a notice to the Trustee and each of the Holders, with a copy to the Trustee. The notice shall contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The Asset Sale Offer shall be made to all Holders. The notice, which shall govern the terms of the Asset Sale Offer, shall state:

(1) that the Asset Sale Offer is being made pursuant to this Section 4.10 and that such Asset Sale Offer shall remain open for 20 Business Days;

(2) the Offer Amount attributable to the Notes, the purchase price and the purchase date of the Notes tendered pursuant to the Asset Sale Offer (the "Purchase Date");

(3) that any Note not tendered or accepted for payment shall continue to accrue interest and Additional Interest, if any;

(4) that, unless the Company defaults in making such payment, any Note accepted for payment pursuant to the Asset Sale Offer shall cease to accrue interest, and Additional Interest, if any;

(5) that Holders electing to have a Note purchased pursuant to any Asset Sale Offer shall be required to surrender the Note, with the form entitled "Option of Holder to Elect Purchase" on the reverse of the Note completed, or transfer by book-entry transfer, to the Company, a Depositary, if appointed by the Company, or a Paying Agent at the address specified in the notice at least three Business Days before the Purchase Date;

(6) that Holders shall be entitled to withdraw their election if the Company, the Depositary or the Paying Agent, as the case may be, receives, not later than the expiration of the offer period, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal

amount of the Note the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Note purchased;

(7) that, if the aggregate accreted value of Notes and aggregate principal amount of such other pari passu Indebtedness tendered by Holders exceeds the Offer Amount, the Company shall select the Notes and such other pari passu Indebtedness to be purchased on a pro rata basis on the basis of the aggregate accreted value of Notes and the aggregate principal amount of such other pari passu Indebtedness tendered (with such adjustments as may be deemed appropriate by the Company so that only Notes in denominations of a minimum of $1,000 aggregate principal amount and integral multiples of $1.00 in excess thereof shall be purchased); and

(8) that Holders whose Notes were purchased only in part shall be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer).

On or before the Purchase Date, the Company shall, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes and such other pari passu Indebtedness or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been tendered, all Notes, and such other pari passuIndebtedness or portions thereof tendered, and shall deliver to the Trustee an Officers' Certificate stating that such Notes, and such other pari passu Indebtedness or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 4.10. The Company, the Depositary or the Paying Agent, as the case may be, shall on the Purchase Date mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Company for purchase, and the Company shall promptly issue a new Note, and the Trustee, upon written request from the Company shall authenticate and mail or deliver such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof. The Company shall publicly announce the results of the Asset Sale Offer promptly after Purchase Date.

If the Purchase Date is on or after an interest payment record date and on or before the related interest payment date, any accrued and unpaid interest and Additional Interest, if any, will be paid to the Holder in whose name a Note is registered at the close of business on such record date, and no interest or Additional Interest, if any, will be payable to Holders who tender Notes pursuant to the Asset Sale Offer.

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the Asset Sale provisions of this Indenture, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Asset Sale provisions of this Indenture by virtue of such conflict.

SECTION 4.11. Transactions with Affiliates

The Company shall not, and shall not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of the Company or

any of its Restricted Subsidiaries (each, an "Affiliate Transaction") involving aggregate consideration in excess of $1.0 million, unless:

(1) the Affiliate Transaction is on terms that are at least as favorable to the Company or the relevant Restricted Subsidiary as those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person, provided that any such Affiliated Transaction shall be conclusively deemed to be at least as favorable as the terms which could be obtained on an arm's length basis with an unrelated Person if such transaction is approved by a majority of the Company's directors (including a majority of the disinterested members of the Board of Directors); and

(2) the Company delivers to the Trustee:

(a) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $2.0 million, a resolution of the Board of Directors set forth in an Officers' Certificate certifying that such Affiliate Transaction complies with this covenant and that such Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors; and

(b) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $10.0 million, or if the Company does not have any disinterested members, an opinion as to the fairness to the holders of the Notes of such Affiliate Transaction from a financial point of view issued by an accounting, appraisal or investment banking firm of national standing selected by the Company.

The following items will not be deemed to be Affiliate Transactions and, therefore, will not be subject to the provisions of the prior paragraph:

(1) transactions between the Company or any of its Restricted Subsidiaries and any employee, officer or director of, or consultant to, the Company, any direct or indirect parent company of the Company, or any of its Restricted Subsidiaries that are approved by the disinterested members of the Board of Directors;

(2) reasonable and customary directors' fees, indemnification and similar arrangements for officers, directors or employees, consulting fees, officer or employee salaries, bonuses or employment agreements, compensation or employee benefit arrangements and incentive arrangements with any officer, director or employee of the Company, any direct or indirect parent company of the Company or any of its Restricted Subsidiaries and payments under any indemnification arrangements permitted by applicable law;

(3) transactions between or among the Company and/or its Restricted Subsidiaries;

(4) transactions with a Person that is an Affiliate of the Company or any Restricted Subsidiary solely because the Company or any Restricted Subsidiary owns an Equity Interest in, or controls, such Person;

(5) the pledge of Equity Interests of Unrestricted Subsidiaries to support the Indebtedness thereof;

(6) issuances and sales of Equity Interests (other than Disqualified Stock) to Affiliates of the Company;

(7) Restricted Payments that are permitted by Section 4.07;

(8) the payment of management fees and related expenses to Aurora Management Partners LLC and its Affiliates; provided that such fees shall not, in the aggregate, exceed $2.0 million (plus out of pocket expenses) in any twelve-month period commencing after the date of this Indenture;

(9) the payment of transaction, consulting and advisory fees and related expenses to Aurora Management Partners LLC and its Affiliates for financial advisory, financing, underwriting or placement services or in respect of other investment banking activities, including without limitation, in connection with acquisitions or divestitures, in each case, which payments are (a) reasonably related to the services performed and (b) either (i) under $10.0 million in any fiscal year or (ii) approved by a majority of the members of the Board of Directors of the Company; and

(10) the payment of all fees and expenses related to the Acquisition Transactions, which are described in the Offering Memorandum.

SECTION 4.12. Liens

The Company shall not create, incur, assume or otherwise cause or suffer to exist any Lien of any kind securing Indebtedness, Attributable Debt or trade payables (other than Permitted Liens) upon any of its property or assets, now owned or hereafter acquired, unless all payments due under this Indenture and the Notes are secured (i) in the case of Liens securing Indebtedness that is pari passu in right of payment to the Notes, on an equal and ratable basis with the obligations so secured until such time as such obligations are no longer secured by a Lien and (ii) in the case of Liens securing Indebtedness that is expressly subordinate or junior in right of payment to the Notes, on a senior basis to the obligations so secured with the same relative priority as the Notes shall have to that subordinated or junior Indebtedness until such time as such obligations are no longer secured by a Lien.

SECTION 4.13. Business Activities

The Company shall not, and shall not permit any Restricted Subsidiary to, engage in any business other than Permitted Businesses, except to such extent as would not be material to the Company and its Subsidiaries taken as a whole.

SECTION 4.14. Corporate Existence

Subject to Article 5 hereof, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect (i) its corporate existence, and the corporate, partnership or other existence of each of its Restricted Subsidiaries, in accordance with the respective organizational documents (as the same may be amended from time to time) of the Company or any such Restricted Subsidiary and (ii) the rights (charter and statutory), licenses and franchises of the Company and its Subsidiaries, except where the failure to do so would not have a material adverse effect on the ability of the Company to perform its obligations under the Notes or this Indenture.

SECTION 4.15. Offer to Repurchase upon Change of Control

If a Change of Control occurs, the Company will be required to make an offer (a "Change of Control Offer") to each Holder of Notes, unless the Company has exercised its right to redeem all the Notes as described under Section 3.07, to repurchase all or any part (equal to $1,000 or an integral multiple of $1,000) of that Holder's Notes on the terms set forth in this Indenture. In the Change of Control Offer, the Company will offer a payment in cash (the "Change of Control Payment") equal to 101% of the aggregate principal amount of the Notes repurchased plus accrued and unpaid interest and Additional Interest, if any, on the Notes repurchased, to the date of purchase (the "Change of Control Payment Date"). Within 30 days following any Change of Control, the Company shall mail a notice to each Holder stating: (i) that the Change of Control Offer is being made pursuant to this Section 4.15 (and describing the transaction or transactions that constitute the Change of Control) and that all Notes tendered shall be accepted for payment; (ii) the purchase price and Change of Control Payment Date, which shall be no earlier than 30 days and no later than 60 days from the date such

notice is mailed; (iii) that any Note not tendered shall continue to accrue interest and Additional Interest, if any; (iv) that, unless the Company defaults in the payment of the Change of Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer shall cease to accrue interest and Additional Interest, if any, after the Change of Control Payment Date; (v) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer shall be required to surrender the Notes, with the form entitled "Option of Holder to Elect Purchase" on the reverse of the Notes completed, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day preceding the Change of Control Payment Date; (vi) that Holders shall be entitled to withdraw their election if the Paying Agent receives, not later than the close of business on the second Business Day preceding the Change of Control Payment Date, a facsimile transmission or letter setting forth the name of the Holder, the principal amount of Notes delivered for purchase, and a statement that such Holder is withdrawing his election to have the Notes purchased; and (vii) that Holders whose Notes are being purchased only in part shall be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be in a minimum principal amount of $2,000 or an integral multiple of $1.00 in excess thereof.

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control provisions of this Indenture, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.15 by virtue of such conflict.

On the Change of Control Payment Date, the Company shall, to the extent lawful:

(1) accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer;

(2) deposit with the paying agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and

(3) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers' Certificate stating the aggregate principal amount of the Notes or portions of Notes being purchased by the Company.

The Paying Agent shall promptly mail to each Holder of Notes validly tendered the Change of Control Payment for such Notes, and the Trustee shall promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each new Note will be in a minimum principal amount of $2,000 or an integral multiple of $1.00 in excess thereof. The Company shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

If the Change of Control Payment Date is on or after an interest payment record date and on or before the related interest payment date, any accrued and unpaid interest and Additional Interest, if any, shall be paid (or Additional PIK Notes shall be issued, in the case the Company elects to pay interest in the form of Additional PIK Notes pursuant to Section 2.15 hereof) to the Holder in whose name a Note is registered at the close of business on such record date, and no other interest or Additional Interest, if any, will be payable to Holders who tender pursuant to the Change of Control Offer.

The Company shall 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 the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer

made by the Company and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer or if an irrevocable notice of redemption has been given pursuant to Section 3.03.

SECTION 4.16. Future Subsidiary Guarantees

The Company will cause each Restricted Subsidiary that guarantees any Indebtedness of the Company to execute and deliver to the Trustee a supplemental indenture in form and substance set forth in Exhibit E pursuant to which such Restricted Subsidiary will guarantee payment of the Notes; provided that, if such Indebtedness is by its terms subordinated in right of payment to the Notes, any such guarantee of such Restricted Subsidiary with respect to such Indebtedness shall be subordinated to such Guarantor's Subsidiary Guarantee substantially to the same extent as such Indebtedness is subordinated to the Notes.

Each Subsidiary Guarantee will be limited to an amount not to exceed the maximum amount that can be guaranteed by that Restricted Subsidiary without rendering the Subsidiary Guarantee, as it relates to such Restricted Subsidiary, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.

SECTION 4.17. Designation of Unrestricted Subsidiaries

The Board of Directors may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate fair market value of all outstanding Investments owned by the Company and its Restricted Subsidiaries in the Subsidiary properly designated will be deemed to be an Investment made as of the time of the designation and will reduce the amount available for Restricted Payments under the first paragraph of Section 4.07 or Permitted Investments, as determined by the Company. That designation will only be permitted if the Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. The Board of Directors may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if the redesignation would not cause a Default.

All Subsidiaries of Unrestricted Subsidiaries shall be automatically deemed to be Unrestricted Subsidiaries. All designations of Subsidiaries as Unrestricted Subsidiaries and revocations thereof must be evidenced by filing with the Trustee resolutions of the Board of Directors of the Company and an Officers' Certificate certifying compliance with the foregoing provisions.

SECTION 4.18. Payments for Consent

The Company shall not, and shall not permit any of its Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any Holder of Notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes unless such consideration is offered to be paid and is paid to all Holders of the Notes that consent, waive or agree to amend in the applicable time frame set forth in the solicitation documents relating to such consent, waiver or agreement.

SECTION 6.02. Acceleration

In the case of an Event of Default arising from clause (9) or (10) of the first paragraph of Section 6.01, with respect to the Company or any Restricted Subsidiary that is a Significant Subsidiary or any group of Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, all outstanding Notes will become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes, by notice in writing to the Trustee and the Company designated as a "Notice of Default," may declare all the Notes to be due and payable and, upon any such declaration, such principal amount (and premium, if any) and accrued interest, notwithstanding anything contained in this Indenture or the Notes to the contrary, will become immediately due and payable. Any such declaration with respect to the Notes may be annulled by the Holders of a majority in aggregate principal amount of the then outstanding Notes upon the conditions set forth herein.

Notwithstanding the foregoing, if an Event of Default specified in clause (6) of Section 6.01 shall have occurred and be continuing, such Event of Default and any consequential acceleration shall be automatically rescinded if (i) the Indebtedness that is the subject of such Event of Default has been repaid, or (ii) if the default relating to such Indebtedness is waived or cured and if such Indebtedness has been accelerated, then the Holders thereof have rescinded their declaration of acceleration in respect of such Indebtedness.

Any such declaration with respect to the Notes may be rescinded and annulled by the Holders of a majority in aggregate principal amount of the outstanding Notes by written notice to the Trustee, except a continuing Default or Event of Default in the payment of principal of, or interest or premium or Additional Interest, if any, on the Notes, if (i) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction, (ii) all existing Events of Default have been cured or waived except nonpayment of principal of or interest on the Notes that has become due solely by such declaration of acceleration, (iii) to the extent the payment of such interest is lawful, interest (at the same rate specified in the Notes) on overdue installments of interest and overdue payments of principal, which has become due otherwise than by such declaration of acceleration, has been paid, (iv) the Company has paid the Trustee its reasonable compensation and reimbursed the Trustee for its expenses, disbursements and advances and (v) in the event of the cure or waiver of a Default or Event of Default of the type described in Section 6.01(9) and (10) the Trustee has received an Officers' Certificate and Opinion of Counsel that such Default or Event of Default has been cured or waived. No such rescission shall affect any subsequent Default or impair any right consequent thereto.

SECTION 6.03. Other Remedies

If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, premium on, Additional Interest, if any, and interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture.

The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law.

SECTION 6.04. Waiver of Past Defaults

Subject to Section 9.02 and in any event in accordance with the conditions set forth in the last paragraph of Section 6.02, Holders of not less than a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may on behalf of the Holders of all of the Notes waive an existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of the principal of, premium and Additional Interest on, or interest on the Notes (including in connection with an offer to purchase); provided that the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration, so long as such acceleration was not the result of a payment default. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture, but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

SECTION 6.05. Control by Majority

Holders of a majority in principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee in personal liability.

SECTION 6.06. Limitation on Suits

A Holder of a Note may pursue a remedy with respect to this Indenture or the Notes only if:

(a) the Holder of a Note gives to the Trustee written notice of a continuing Event of Default;

(b) the Holders of at least 25% in principal amount of the then outstanding Notes make a written request to the Trustee to pursue the remedy;

(c) such Holder of a Note or Holders of Notes offer and, if requested, provide to the Trustee indemnity satisfactory to the Trustee against any loss, liability or expense;

(d) the Trustee does not comply with the request within 60 days after receipt of the request and the offer and, if requested, the provision of indemnity; and

(e) during such 60-day period the Holders of a majority in principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with the request.

A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note.

SECTION 6.07. Rights of Holders of Notes to Receive Payment

Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal, premium and Additional Interest, if any, and interest on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder.

SECTION 6.08. Collection Suit by Trustee

If an Event of Default specified in Section 6.01(1) or (2) occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of principal of, premium and Additional Interest, if any, and interest remaining unpaid on the Notes and interest on overdue principal and, to the extent lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

SECTION 6.09. Trustee May File Proofs of Claim

The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

SECTION 6.10. Priorities

After an Event of Default, any money or other property distributable in respect of the Company's obligations under this Indenture shall be paid in the following order:

First: to the Trustee (including any predecessor Trustee), its agents and attorneys for amounts due under Section 7.07 hereof, including payment of all compensation, expense and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection;

Second: to Holders of Notes for amounts due and unpaid on the Notes for principal, premium and Additional Interest, if any, and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium and Additional Interest, if any and interest, respectively; and

Third: to the Company or to such party as a court of competent jurisdiction shall direct in writing.

The Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 6.10.

SECTION 6.11. Undertaking for Costs

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys' fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in principal amount of the then outstanding Notes.

SECTION 7.03. Individual Rights of Trustee

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee. If the Trustee does become a creditor of the Company, this indenture limits its rights to obtain payment of claims in certain cases, or to realize on certain property received in respect of any such claim as security or otherwise. However, in the event that the Trustee acquires any conflicting interest it must eliminate such conflict within 90 days, apply to the Commission for permission to continue as trustee or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof.

SECTION 7.04. Trustee's Disclaimer

SECTION 7.05. Notice of Defaults

If a Default or Event of Default occurs and is continuing and if it is actually known to a Responsible Officer of the Trustee, the Trustee shall mail to Holders of Notes a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, premium and Additional Interest, if any, or interest on any Note, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of the Notes.

SECTION 7.06. Reports by Trustee to Holders of the Notes

Within 60 days after each May 15 beginning with the May 15 following the Issue Date, and for so long as Notes remain outstanding, the Trustee shall mail to the Holders of the Notes a brief report dated as of such reporting date that complies with TIA § 313(a) (but if no event described in TIA § 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also shall comply with TIA § 313(b)(2) to the extent applicable. The Trustee shall also transmit by mail all reports as required by TIA § 313(c).

A copy of each report at the time of its mailing to the Holders of Notes shall be mailed to the Company and filed with the Commission and each stock exchange on which the Notes are listed in accordance with TIA § 313(d). The Company shall promptly notify the Trustee when the Notes are listed on any stock exchange or any delisting thereof.

SECTION 7.07. Compensation and Indemnity

The Company shall pay to the Trustee from time to time reasonable compensation for its acceptance of this Indenture and services hereunder. The Trustee's compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee promptly upon written request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee's agents and counsel.

The Company shall indemnify the Trustee against any and all losses, liabilities or expenses incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Company (including this Section 7.07) and defending itself against any claim (whether asserted by the Company or any Holder or any other person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, liability or expense may be attributable to its negligence or bad faith or willful misconduct. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel and the Company shall pay the reasonable fees and expenses of such counsel. The Company need not pay for any settlement made without its consent.

The obligations of the Company under this Section 7.07 shall survive the resignation or removal of the Trustee, the satisfaction and discharge of this Indenture and the termination of this Indenture.

To secure the Company's payment obligations in this Section, the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on particular Notes. Such Lien shall survive the resignation or removal of the Trustee, the satisfaction and discharge of this Indenture and the termination of this Indenture.

In addition and without prejudice to its rights hereunder, when the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(9) or (10) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law.

SECTION 7.08. Replacement of Trustee

A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee's acceptance of appointment as provided in this Section.

The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Company. The Holders of Notes of a majority in principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Company in writing. The Company may remove the Trustee if:

(a) the Trustee fails to comply with Section 7.10 hereof;

(b) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law;

(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 Holders of a majority in principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Company.

If a successor Trustee does not take office within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of Notes of at least 10% in principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee.

If the Trustee, after written request by any Holder of a Note who has been a Holder of a Note for at least six months, fails to comply with Section 7.10, such Holder of a Note may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders of the Notes. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee; provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Company's obligations under Section 7.07 hereof shall continue for the benefit of the retiring Trustee.

SECTION 7.09. Successor Trustee by Merger, etc.

If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another Person, the successor Person without any further act shall be the successor Trustee.

SECTION 7.10. Eligibility; Disqualification

There shall at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least $50 million as set forth in its most recent published annual report of condition.

This Indenture shall always have a Trustee who satisfies the requirements of TIA § 310(a)(1), (2) and (5). The Trustee is subject to TIA § 310(b). Nothing herein shall prohibit the Trustee from making the application to the Commission referred to in the penultimate paragraph of Section 310(b) of the TIA.

For purposes of Section 310(b)(1) of the TIA and to the extent permitted thereby, the Trustee shall not be deemed to have a conflicting interest arising from its capacity as trustee in respect of the indenture governing the Existing Notes.

SECTION 7.11. Preferential Collection of Claims Against the Company

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

For this purpose, Legal Defeasance means that the Company and the Guarantors, if any, shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes (including any Subsidiary Guarantees), which shall thereafter be deemed to be "outstanding" only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in (a) and (b) below, and to have satisfied all its other obligations under such Notes, the Subsidiary Guarantees, if any, and this Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same); provided that the following provisions which shall survive until otherwise terminated or discharged hereunder: (a) the rights of Holders of outstanding Notes to receive solely from the trust fund described in Section 8.04 hereof, and as more fully set forth in such Section, payments in respect of the principal of or premium, if any, Additional Interest, if any, or interest on the Notes when such payments are due, (b) the Company's obligations with respect to the Notes concerning issuing temporary Notes, registration of Notes and mutilated, destroyed, lost or stolen Notes and the maintenance of an office or agency for payment and money for security payments held in trust, (c) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Company's and the Guarantors', if any, obligations in connection therewith and (d) this Article 8. Subject to compliance with this Article 8, the Company may exercise its option under this Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 hereof.

SECTION 8.03. Covenant Defeasance

Upon the Company's exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Company and the Guarantors, if any, shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from its obligations under the covenants contained in Article 4 (other those in Sections 4.01, 4.02, 4.06 and 4.14) and in clause (3) of Section 5.01(4) hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 are satisfied (hereinafter, "Covenant Defeasance"), and the Notes shall thereafter

be deemed not "outstanding" for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed "outstanding" for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and any Subsidiary Guarantees, the Company and the Guarantors, if applicable, may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes and any Subsidiary Guarantees shall be unaffected thereby. In addition, upon the Company's exercise under Section 8.01 hereof of the option applicable to this Section 8.03 hereof, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(6) through 6.01(8) hereof shall not constitute Events of Default.

SECTION 8.04. Conditions to Legal or Covenant Defeasance

The following shall be the conditions to the application of either Section 8.02 or 8.03 hereof to the outstanding Notes:

(1) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of the Notes, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in amounts as will be sufficient, in the opinion of a nationally recognized investment bank or firm of independent public accountants, to pay the principal of, or interest and premium and Additional Interest, if any, on the outstanding Notes on the Stated Maturity or on the applicable redemption date specified by the Company, as the case may be, and the Company must specify whether the Notes are being defeased to maturity or to a particular redemption date;

(2) in the case of an election under Section 8.02 hereof, the Company has delivered to the Trustee an opinion of counsel 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 will confirm that, the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

(3) in the case of an election under Section 8.03 hereof, the Company has delivered to the Trustee an opinion of counsel reasonably acceptable to the Trustee confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

(4) no Default or Event of Default has occurred and is continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit) or insofar as Events of Default from bankruptcy or insolvency events are concerned, at any time in the period ending on the 91st day after the date of deposit;

(5) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than this Indenture) to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound;

(6) the Company must have delivered to the Trustee an opinion of counsel, subject to customary qualifications, to the effect that after the 91st day following the deposit, no trust funds will be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors' rights generally or in connection with Covenant Defeasance, such trust funds will be subject to a first priority lien in favor of the Trustee for the benefit of the Holders of Notes;

(7) the Company must deliver to the Trustee an Officers' Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders of Notes over the other creditors of the Company with the intent of defeating, hindering, delaying or defrauding creditors of the Company or others; and

(8) the Company must deliver to the Trustee an Officers' Certificate and an opinion of counsel, each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with.

SECTION 8.05. Deposited Money and Government Securities to Be Held in Trust; Other Miscellaneous Provisions

Subject to Section 8.06 hereof, all money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the "Trustee") pursuant to Section 8.04 hereof in respect of the outstanding Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal of or premium, if any, Additional Interest, if any, or interest, but such money need not be segregated from other funds except to the extent required by law.

The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable Government Securities deposited pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes.

Anything in this Article 8 to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon the request of the Company any money or non-callable Government Securities held by it as provided in Section 8.04 hereof 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 8.04(a) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

SECTION 8.06. Repayment to the Company

Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of or premium, if any, Additional Interest, if any, or interest on the Notes and remaining unclaimed for two years after such principal, and premium, if any, Additional Interest, if any, or interest has become due and payable shall be paid to the Company on its request or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter, as a secured creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as

trustee thereof, shall thereupon cease; provided that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in The New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining shall be repaid to the Company.

SECTION 8.07. Reinstatement

If the Trustee or Paying Agent is unable to apply any United States dollars or non-callable Government Securities in accordance with Section 8.02 or 8.03 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company's and, if any, the Guarantors' obligations under this Indenture and the Notes and, if applicable, the Subsidiary Guarantees shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as the case may be; provided that, if the Company has made any payment of principal of, premium, if any, Additional Interest, if any, or interest on any Note following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent.

ARTICLE 9
AMENDMENT, SUPPLEMENT AND WAIVER

SECTION 9.01. Without Consent of Holders of Notes

Notwithstanding Section 9.02 of this Indenture, the Company and the Trustee may amend or supplement this Indenture or the Notes without the consent of any Holder of a Note to:

(1) cure any ambiguity, defect or inconsistency;

(2) provide for uncertificated Notes in addition to or in place of certificated Notes (provided that the uncertificated Notes are issued in registered form for purposes of Section 163(f) of the Code, or in a manner such that the uncertificated Notes are described in Section 163(f)(2)(B) of the Code);

(3) provide for the assumption of the Company's obligations to Holders of Notes in the case of a merger or consolidation or sale of all or substantially all of the Company's assets;

(6) evidence and provide for the acceptance of an appointment of a successor trustee;

(7) conform this Indenture or the Notes to the "Description of Notes" set forth in the Offering Memorandum;

(8) add Subsidiary Guarantees with respect to the Notes; or

Upon the request of the Company accompanied by a resolution of the Board of Directors of the Company authorizing the execution of any such amended or supplemental indenture, and upon receipt by the Trustee of the documents described in Section 9.06 hereof, the Trustee shall join with the

Company in the execution of any amended or supplemental Indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to enter into such amended or supplemental Indenture that affects its own rights, duties or immunities under this Indenture or otherwise.

SECTION 9.02. With Consent of Holders of Notes

Except as provided in Section 9.01 or below in this Section 9.02, the Company and the Trustee may amend or supplement this Indenture and the Notes may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the Notes then outstanding voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default or compliance with any provision of this Indenture or the Notes may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes). Section 2.09 hereof shall determine which Notes are considered to be "outstanding" for purposes of this Section 9.02.

However, without the consent of each Holder affected, an amendment or waiver under this Section 9.02 may not (with respect to any Notes held by a nonconsenting Holder):

(1) reduce the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver;

(2) reduce the principal of (or the premium on) or change the fixed maturity of any Note or alter the provisions with respect to the redemption of the Notes (other than provisions relating to the covenants contained in Section 4.10 and Section 4.15);

(3) reduce the rate of or change the time for payment of interest or Additional Interest on any Note;

(4) waive a Default or Event of Default in the payment of principal of, or interest or premium or Additional Interest, if any, on the Notes (except a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the Notes and a waiver of the payment default that resulted from such acceleration);

(5) make any Note payable in currency other than that stated in the Notes;

(6) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders of Notes to receive payments of principal of, or interest or premium or Additional Interest, if any, on the Notes;

(7) waive a redemption payment with respect to any Note (other than a payment required by Section 4.10 or Section 4.15);

(8) release any Guarantor from any of its obligations under its Subsidiary Guarantee or this Indenture, except in accordance with the terms of this Indenture; or

(9) make any change in the preceding amendment and waiver provisions.

In addition, any amendment to, or waiver of, the provisions of this Indenture relating to subordination that adversely affects the rights of the Holders of the Notes will require the consent of the Holders of at least 75% in aggregate principal amount of Notes then outstanding.

Upon the request of the Company accompanied by a resolution of the Board of Directors of the Company authorizing the execution of any such amended or supplemental Indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as

aforesaid, and upon receipt by the Trustee of the documents described in Section 9.06 hereof, the Trustee shall join with the Company in the execution of such amended or supplemental Indenture unless such amended or supplemental Indenture directly affects the Trustee's own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental Indenture.

SECTION 9.03. Compliance with Trust Indenture Act

Every amendment or supplement to this Indenture or the Notes shall be set forth in an amended or supplemental Indenture that complies with the TIA as then in effect.

SECTION 9.04. Revocation and Effect of Consents

Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder's Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder.

SECTION 9.05. Notice of Amendment; Notation on or Exchange of Notes

After any amendment under this Article becomes effective, the Company shall mail to Holders of Notes a notice briefly describing such amendment. The failure to give such notice to all Holders of Notes, or any defect therein, shall not impair or affect the validity of an amendment under this Article.

The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Company in exchange for all Notes may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver.

Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver.

SECTION 9.06. Trustee to Sign Amendments, etc.

The Trustee shall sign any amended or supplemental Indenture authorized pursuant to this Article 9 if the amendment or supplement, in the sole discretion of the Trustee, does not adversely affect the rights, duties, liabilities or immunities of the Trustee. In executing any amended or supplemental indenture, the Trustee shall be entitled to receive and (subject to Section 7.01 hereof) shall be fully protected in relying upon, in addition to the documents required by Section 12.04 hereof, an Officers' Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture.

ARTICLE 10
SUBSIDIARY GUARANTEES

SECTION 10.01. Guarantee

(a) Subject to this Article 10, each of the Guarantors, if any, hereby, jointly and severally, unconditionally guarantees 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 of this Indenture, the Notes or the obligations of the Company hereunder or thereunder, that:

(i) the principal of, premium and Additional Interest, if any, and interest on the Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Company to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof, and

(ii) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration or otherwise.

Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors will be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

(b) The Guarantors hereby agree that their obligations hereunder are unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor.

(c) Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenant that this Subsidiary Guarantee will not be discharged except by complete performance of the obligations contained in the Notes and this Indenture.

(d) If any Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the Company or the Guarantors, any amount paid by either to the Trustee or such Holder, this Subsidiary Guarantee, to the extent theretofore discharged, will be reinstated in full force and effect.

(e) 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 the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (1) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (2) in the event of any declaration of acceleration of such obligations as provided in Article 6 hereof, such obligations (whether or not due and payable) will forthwith become due and payable by the Guarantors for the purpose of this Subsidiary Guarantee.

(f) The Guarantors will have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Subsidiary Guarantee.

SECTION 10.02. Limitation on Guarantor Liability

Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Subsidiary Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent

applicable to any Subsidiary Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor will be limited to the maximum amount that will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article 10, result in the obligations of such Guarantor under its Subsidiary Guarantee not constituting a fraudulent transfer or conveyance.

SECTION 10.03. Guarantors May Consolidate, etc., on Certain Terms

No Guarantor may sell or otherwise dispose of all or substantially all of its assets to, or consolidate with or merge with or into (whether or not such Guarantor is the surviving Person), another Person, other than the Company or another Guarantor, unless:

(1) immediately after giving effect to such transaction, no Default or Event of Default exists; and

(2) either:

(a) the Person acquiring the property in any such sale or disposition or the Person formed by or surviving any such consolidation or merger unconditionally assumes all the obligations of that Guarantor under this Indenture (including its Subsidiary Guarantee) and the Registration Rights Agreement pursuant to agreements reasonably satisfactory to the trustee; or

(b) the Net Proceeds of such sale or other disposition will be required to be applied in accordance with the applicable provisions of this Indenture.

SECTION 10.04. Releases of Subsidiary Guarantees

The Subsidiary Guarantee of a Guarantor will be released:

(1) in connection with any sale, disposition or other transfer (including through merger or consolidation) of (x) the Equity Interests of such Guarantor following which such Guarantor is no longer a Subsidiary of the Company or (y) all or substantially all the assets of the applicable Guarantor, in each case, to a Person that is not (either before or after giving effect to such transaction) a Subsidiary of the Company if such sale, disposition or other transfer is made in compliance with the applicable provisions of this Indenture;

(2) upon the release or discharge of the guarantee by such Guarantor of Indebtedness of the Company which resulted in the obligation to guarantee the Notes;

(3) in connection with the Legal Defeasance of the Notes and the Subsidiary Guarantees; or

(4) if the Company designates any Restricted Subsidiary that is a Guarantor as an Unrestricted Subsidiary in accordance with the applicable provisions of this Indenture.

ARTICLE 11

(including the Company acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest and Additional Interest, if any, but such cash and securities need not be segregated from other funds except to the extent required by law.

SECTION 11.03. Repayment to Company

Any cash or non-callable Government Securities deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium, if any, or interest or Additional Interest, if any, on, any Note and remaining unclaimed for two years after such principal, and premium, if any, or interest or Additional Interest, if any, has become due and payable shall be paid to the Company on its request or (if then held by the Company) shall be discharged from such trust; and the Holder shall thereafter, as an unsecured creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such cash and securities, and all liability of the Company as trustee thereof, shall thereupon cease; provided 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 cash and securities 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 cash and securities then remaining will be repaid to the Company.

SECTION 12.15. Legal Holidays

Interest on the Notes shall accrue from the most recent date to which interest has been paid (whether in cash or in Additional PIK Notes) or, if no interest has been paid, from the date of issuance[; provided that if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date]². Interest shall be computed on the basis of a 360-day year of twelve 30-day months.

(2) Method of Payment. The Company shall pay interest on the Notes (except defaulted interest) and Additional Interest, if any, to the Persons in whose name(s) this Note (or one or more Predecessor Notes) is registered at the close of business on the January 15 or July 15 next preceding the Interest Payment Date (each, a "Record Date"), even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.13 of the Indenture with respect to defaulted interest.

The Notes shall be payable as to principal of or premium (if any), Additional Interest (if any and if paid in cash), or interest (if paid in cash) at the office or agency of the Company maintained for such purpose within or without the City and State of New York, or, at the option of the Company, payment of interest and Additional Interest, if any, may be made (i) by check mailed to the Holders at their addresses set forth in the register of Holders or (ii) in the form of Additional PIK Notes to the accounts specified by DTC (or, if Notes are held in the form of Definitive Notes, to the Holders by mail at their address set forth in the register of Holders); provided, payment by wire transfer of immediately available funds shall be required with respect to principal of or premium (if any), Additional Interest (if any and if the Company elects to pay Additional Interest in cash), or interest (if the Company elects to pay interest in cash) on, the Global Notes and all other Notes the Holders of which shall have provided wire transfer instructions to the Company or the Paying Agent prior to the applicable Record Date.

The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are obligations of the Company initially in the aggregate principal amount of $55,000,000. Subject to compliance with Section 2.16 of the Indenture, the Company is permitted to issue Additional Notes under the Indenture in an unlimited principal amount. Any such Additional Notes that are actually issued shall be treated as issued and outstanding Notes (and as the same class as the Initial Notes) for all purposes of the Indenture, unless the context clearly indicated otherwise.

(5) Optional Redemption.

(a) Except as set forth in clause (b) of this Paragraph 5, the Company shall not have the option to redeem the Notes pursuant to Section 3.07 of the Indenture prior to February 1, 2007. Thereafter, the Company shall have the option to redeem the Notes, in whole or in part, at the redemption prices (expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest and Additional Interest thereon, if any, to the applicable redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), if redeemed during the twelve-month period beginning on February 1 of the years indicated below:

Year		Percentage
2007		102.000%
2008		101.000%
2009 and thereafter		100.000%

(b) Notwithstanding the provisions of clause (a) of this Paragraph 5, at any time prior to February 1, 2007, the Company may redeem (i) on any one or more occasions up to 35% or (ii) 100% (but, other than as provided in the foregoing clause (i), not less than 100%) of the aggregate principal amount of Notes issued under this Indenture (including any Additional PIK Notes and any Additional Notes) at a redemption price equal to 105.750% of the principal amount thereof on the redemption date, plus accrued and unpaid interest and Additional Interest, if any, to the redemption date, with the net cash proceeds of one or more Equity Offerings by the Company; provided that (1) in the case of a redemption pursuant to clause (i) above, at least 65% of the aggregate principal amount of Notes issued under this Indenture remains outstanding immediately after the occurrence of such redemption (excluding Notes held by the Company and its Subsidiaries); and (2) that such redemption shall occur within 90 days of the date of the closing of such Equity Offering.

(6) Repurchase at Option of Holder.

(a) Upon the occurrence of a Change of Control, each Holder of Notes shall have the right to require the Company to repurchase all or any part (equal to $1,000 or an integral multiple of $1,000) of such Holder's Notes pursuant to the offer described below (the "Change of Control Offer") at an offer price in cash equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest and Additional Interest, if any, thereon to the date of purchase (the "Change of Control Payment"). Within 30 days following any Change of Control, the Company

A-4

shall mail a notice to each Holder setting forth the procedures governing the Change of Control Offer as required by the Indenture.

(b) If the Company or a Restricted Subsidiary consummates any Asset Sales, when the aggregate amount of Excess Proceeds exceeds $10 million, the Company or the applicable Restricted Subsidiary shall commence an offer to all Holders pursuant to Section 4.10 of the Indenture to purchase the maximum principal amount of Notes (an "Asset Sale Offer") to all Holders of Notes and all holders of such other Indebtedness of the Company that is pari passu with the Notes containing provisions similar to those set forth in the Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets that may be purchased out of the Excess Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount thereof plus accrued and unpaid interest and Additional Interest, if any, thereon to the date of purchase, in accordance with the procedures set forth in the Indenture. To the extent that any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use such Excess Proceeds for any purpose not otherwise prohibited by the Indenture. If the aggregate principal amount of Notes and other pari passu Indebtedness tendered in such Asset Sale Offer exceeds the amount of Excess Proceeds, the Excess Proceeds will be allocated by the Company to the Notes and such other pari passu Indebtedness on a pro rata basis (based upon the respective principal amounts (or accreted value, if applicable) of the Notes and such other pari passu Indebtedness tendered into such Asset Sale Offer) and the portion of each Note to be purchased will thereafter be determined by the Trustee on a pro rata basis among the Holders of such Notes with appropriate adjustments such that the Notes may only be purchased in a minimum of $1,000 aggregate principal amount and integral multiples of $1.00 in excess thereof. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds shall be reset to zero. Holders of Notes that are the subject of an offer to purchase shall receive an Asset Sale Offer from the Company prior to any related purchase date and may elect to have such Notes purchased by completing the form entitled "Option of Holder to Elect Purchase" on the reverse of the Notes.

(7) Notice of Redemption. Notice of redemption shall be mailed 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 whole multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed on the basis of the aggregate principal amount (or accreted value, as applicable) of Notes and other pari passu Indebtedness tendered.

(8) Denominations, Transfer, Exchange. The Notes are in registered form without coupons in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof; provided, however, that Additional PIK Notes shall be issued in denominations of $1.00 and integral multiples of $1.00. 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 in part. Also, the Company 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. No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

(9) Persons Deemed Owners. The registered Holder of a Note may be treated as its owner for all purposes.

The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Company is required upon becoming aware of any Event of Default, to deliver to the Trustee a statement specifying such Event of Default.
