If the Issuer or any Restricted Subsidiary directly or indirectly guarantees Indebtedness of a third Person, the preceding sentence shall give effect to the incurrence of such guaranteed Indebtedness as if the Issuer or such Restricted Subsidiary had directly incurred or otherwise assumed such guaranteed Indebtedness. For purposes of calculating the Consolidated Interest Coverage Ratio prior to the expiration of the first Four-Quarter Period subsequent to the Issue Date, such calculation shall be on the same PRO FORMA basis as the PRO FORMA financial statements that are presented in the Offering Memorandum. In calculating Consolidated Interest Expense for purposes of determining the denominator (but not the numerator) of this Consolidated Interest Coverage Ratio: (1) interest on outstanding Indebtedness determined on a fluctuating basis as of the Transaction Date and which will continue to be so determined thereafter shall be deemed to have accrued at a fixed rate PER ANNUM equal to the rate of interest on this Indebtedness in effect on the Transaction Date; (2) if interest on any Indebtedness actually incurred on the Transaction Date may optionally be determined at an interest rate based upon a factor of a prime or similar rate, a eurocurrency interbank offered rate, or other rates, then the interest rate in effect on the Transaction Date will be deemed to have been in effect during the Four-Quarter Period; and (3) notwithstanding clause (1) or (2) above, interest on Indebtedness determined on a fluctuating basis, to the extent such interest is covered by agreements relating to Hedging Obligations, shall be deemed to accrue at the rate PER ANNUM resulting after giving effect to the operation of these agreements.

SECTION 2.06. TRANSFER AND EXCHANGE. Subject to Sections 2.15 and 2.16, when Notes are presented to the Registrar with a request to register the transfer of such Notes or to exchange such Notes for an equal principal amount of Notes of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested if its requirements for such transaction are met; PROVIDED, HOWEVER, that the Notes surrendered for transfer or exchange shall be duly endorsed or accompanied by a written instrument of transfer in form satisfactory to the Issuer and the Registrar, duly executed by the Holder thereof or his or her attorney duly authorized in writing. To permit registrations of transfers and exchanges, the Issuer shall execute and the Trustee shall authenticate Notes at the Registrar's request. No service charge shall be made for any registration of transfer or exchange, but the Issuer may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith. Without the prior written consent of the Issuer, the Registrar shall not be required to register the transfer of or exchange of any Note (i) during a period beginning at the opening of business 15 days before the mailing of a notice of redemption of Notes and ending at the close of business on the day of such mailing, (ii) selected for redemption in whole or in part pursuant to Article Three, except the unredeemed portion of any Note being redeemed in part, and (iii) beginning at the opening of business on any Record Date and ending on the close of business on the related Interest Payment Date. Any Holder of a beneficial interest in a Global Note shall, by acceptance of such beneficial interest, agree that transfers of beneficial interests in such Global Notes may be effected only through -30- <Page> a book-entry system maintained by the Holder of such Global Note (or its agent) in accordance with the applicable legends thereon, and that ownership of a beneficial interest in the Note shall be required to be reflected in a book-entry system. SECTION 2.07. REPLACEMENT NOTES. If a mutilated Note is surrendered to the Trustee or if the Holder of a Note claims that the Note has been lost, destroyed or wrongfully taken, the Issuer shall issue and the Trustee shall authenticate a replacement Note if the Trustee's requirements are met. Such Holder must provide an indemnity bond or other indemnity, sufficient in the judgment of both the Issuer and the Trustee, to protect the Issuer, the Trustee or any Agent from any loss which any of them may suffer if a Note is replaced. The Issuer may charge such Holder for its reasonable out-of-pocket expenses in replacing a Note pursuant to this Section 2.07, including reasonable fees and expenses of counsel and of the Trustee. Every replacement Note is an additional obligation of the Issuer and every replacement Note Guarantee shall constitute an additional obligation of the Guarantor thereof. The provisions of this Section 2.07 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of lost, destroyed or wrongfully taken Notes. SECTION 2.08. OUTSTANDING NOTES. Notes outstanding at any time are all the Notes that have been authenticated by the Trustee except those cancelled by it, those delivered to it for cancellation and those described in this Section 2.08 as not outstanding. A Note does not cease to be outstanding because the Issuer, the Guarantors or any of their respective Affiliates hold the Note (subject to the provisions of Section 2.09). If a Note is replaced pursuant to Section 2.07 (other than a mutilated Note surrendered for replacement), it ceases to be outstanding unless a Responsible Officer of the Trustee receives proof satisfactory to it that the replaced Note is held by a BONA FIDE purchaser. A mutilated Note ceases to be outstanding upon surrender of such Note and replacement thereof pursuant to Section 2.07. If the principal amount of any Note is considered paid under Section 4.01, it ceases to be outstanding and interest ceases to accrue. If on a Redemption Date or the Maturity Date the Trustee or Paying Agent (other than the Issuer or an Affiliate thereof) holds U.S. Legal Tender or U.S. Government Obligations sufficient to pay all of the principal and interest due on the Notes payable on that date, then on and after that date such Notes cease to be outstanding and interest on them ceases to accrue. SECTION 2.09. TREASURY NOTES. In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Issuer or any of its Affiliates shall be disregarded, 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 disregarded. -31- <Page> SECTION 2.10. TEMPORARY NOTES. Until definitive Notes are ready for delivery, the Issuer may prepare and the Trustee shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of definitive Notes but may have variations that the Issuer considers appropriate for temporary Notes. Without unreasonable delay, the Issuer shall prepare and the Trustee shall authenticate definitive Notes in exchange for temporary Notes. Until such exchange, temporary Notes shall be entitled to the same rights, benefits and privileges as definitive Notes. Notwithstanding the foregoing, so long as the Notes are represented by a Global Note, such Global Note may be in typewritten form. SECTION 2.11. CANCELLATION. The Issuer at any time may deliver Notes to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Notes surrendered to them for transfer, exchange or payment. The Trustee, or at the direction of the Trustee, the Registrar or the Paying Agent (other than the Issuer or a Subsidiary), and no one else, shall cancel and, at the written direction of the Issuer, shall dispose of all Notes surrendered for transfer, exchange, payment or cancellation in accordance with its customary procedures. Certification of the destruction of all cancelled Notes shall be delivered to the Issuer upon request by the Issuer. Subject to Section 2.07, the Issuer may not issue new Notes to replace Notes that it has paid or delivered to the Trustee for cancellation. If the Issuer or any Guarantor shall acquire any of the Notes, such acquisition shall not operate as a redemption or satisfaction of the Indebtedness represented by such Notes unless and until the same are surrendered to the Trustee for cancellation pursuant to this Section 2.11. SECTION 2.12. DEFAULTED INTEREST. If the Issuer defaults in a payment of interest on the Notes, it shall pay the defaulted interest, plus (to the extent lawful) any interest payable on the defaulted interest, in any lawful manner. The Issuer may pay the defaulted interest to the persons who are Holders on a subsequent special record date, which date shall be the fifteenth day next preceding the date fixed by the Issuer for the payment of defaulted interest or the next succeeding Business Day if such date is not a Business Day. At least 15 days before any such subsequent special record date, the Issuer (or, upon the written request of the Issuer, the Trustee in the name and at the expense of the Issuer) shall mail to each Holder, with a copy to the Trustee, a notice that states the subsequent special record date, the payment date and the amount of defaulted interest, and interest payable on such defaulted interest, if any, to be paid. SECTION 2.13. CUSIP AND ISIN NUMBERS. The Issuer in issuing the Notes may use "CUSIP" or "ISIN" numbers, and if so, the Trustee shall use the "CUSIP" or "ISIN" numbers in notices of redemption or exchange as a convenience to Holders; PROVIDED, HOWEVER, that any such notice may state that no representation is made as to the correctness or accuracy of the "CUSIP" or "ISIN" numbers printed in the notice or on the Notes, and that reliance may be placed only on the other identification numbers printed on the Notes. The Issuer will promptly notify the Trustee of any change in the "CUSIP" or "ISIN" numbers. SECTION 2.14. DEPOSIT OF MONEYS. Subject to Section 2 of the Notes, prior to 10:00 a.m. New York City time on each Interest Payment Date, Maturity Date, Redemption Date, Change of Control Payment Date and Net Proceeds Payment Date, the Issuer shall have deposited with the Paying Agent in immediately available funds -32- <Page> money sufficient to make cash payments, if any, due on such Interest Payment Date, Maturity Date, Redemption Date, Change of Control Payment Date and Net Proceeds Payment Date, as the case may be, in a timely manner which permits the Paying Agent to remit payment to the Holders on such Interest Payment Date, Maturity Date, Redemption Date, Change of Control Payment Date and Net Proceeds Payment Date, as the case may be.

(a) The Global Notes initially shall (i) be registered in the name of the Depository or the nominee of such Depository, (ii) be delivered to the Trustee as custodian for such Depository and (iii) bear legends as set forth in EXHIBIT B, as applicable. Members of, or participants in, the Depository ("PARTICIPANTS") shall have no rights under this Indenture with respect to any Global Note held on their behalf by the Depository, or the Trustee as its custodian, or under the Global Note, and the Depository may be treated by the Issuer, the Trustee and any agent of the Issuer or the Trustee as the absolute owner of the Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Issuer, the Trustee or any agent of the Issuer or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depository or impair, as between the Depository and Participants, the operation of customary practices governing the exercise of the rights of a Holder of any Note. (b) Transfers of Global Notes shall be limited to transfers in whole, but not in part, to the Depository, its successors or their respective nominees. Interests of beneficial owners in the Global Notes may be transferred or exchanged for Physical Notes in accordance with the rules and procedures of the Depository and the provisions of Section 2.16. In addition, Physical Notes shall be transferred to all beneficial owners in exchange for their beneficial interests in Global Notes if (i) the Depository notifies the Issuer that it is unwilling or unable to act as Depository for any Global Note, the Issuer so notifies the Trustee in writing and a successor Depository is not appointed by the Issuer within 90 days of such notice, (ii) the Issuer, at its option, notifies the Trustee in writing that it elects to cause the issuance of the Notes in the form of Physical Notes under this Indenture, or (iii) a Default or Event of Default has occurred and is continuing and the Registrar has received a written request from any owner of a beneficial interest in a Global Note to issue Physical Notes.

All such Physical Notes shall bear the applicable legends, if any. (c) In connection with any transfer or exchange of a portion of the beneficial interest in a Global Note to beneficial owners pursuant to paragraph (b) of this Section 2.15, the Registrar shall (if one or more Physical Notes are to be issued) reflect on its books and records the date and a decrease in the principal amount of such Global Note in an amount equal to the principal amount of the beneficial interest in the Global Note to be transferred, and the Issuer shall execute, and the Trustee shall authenticate and deliver, one or more Physical Notes of authorized denominations in an aggregate principal amount equal to the principal amount of the beneficial interest in the Global Note so transferred. (d) In connection with the transfer of a Global Note as an entirety to beneficial owners pursuant to paragraph (b) of this Section 2.15, such Global Note shall be deemed to be surrendered to the Trustee for cancellation, and (i) the Issuer shall execute, (ii) the Guarantors shall execute notations of Note Guarantees on and (iii) the Trustee shall upon written instructions from the Issuer authenticate and deliver, to each beneficial owner identified by the Depository in exchange for its beneficial interest in such Global Note, an equal aggregate principal amount of Physical Notes of authorized denominations. -33- <Page> (e) Any Physical Note constituting a Restricted Security delivered in exchange for an interest in a Global Note pursuant to paragraph (b) or (c) of this Section 2.15 shall, except as otherwise provided by Section 2.16, bear the Private Placement Legend. (f) The Holder of any Global Note may grant proxies and otherwise authorize any Person, including Participants and Persons that may hold interests through Participants, to take any action which a Holder is entitled to take under this Indenture or the Notes.

The Trustee shall promptly notify the Issuer in writing of the Notes selected for redemption and, in the case of any Note selected for partial redemption, the principal amount thereof to be redeemed. Notes and portions of Notes selected shall be in the amounts of $1,000 or integral multiples of $1,000, except that if all of the Notes of a Holder are to be redeemed, the entire outstanding amount of the Notes held by such Holder, even if not an integral multiple of $1,000, shall be redeemed. Except as provided in the preceding sentence, provisions of this Indenture that apply to the Notes called for redemption also apply to portions of Notes called for redemption. SECTION 3.03.

The notice, if mailed in a manner herein provided, shall be conclusively presumed to have been given, whether or not the Holder receives such notice. In any case, failure to give such notice by mail or any defect in the notice to the Holder of any Note designated for redemption in whole or in part shall not affect the validity of the proceedings for the redemption of any other Note. Notices of redemption may not be conditional. At the Issuer's request, the Trustee shall give the notice of redemption in the Issuer's name and at its expense; PROVIDED, HOWEVER, that the Issuer shall have delivered to the Trustee, at least 45 days (or such shorter period allowed by the Trustee) prior to the redemption date, an Officers' Certificate requesting that the Trustee give such notice (in the name and at the expense of the Issuer) and setting forth the information to be stated in such notice as provided in this Section 3.03. SECTION 3.04. EFFECT OF NOTICE OF REDEMPTION.

On or before 10:00 a.m. New York time on the Redemption Date, the Issuer shall deposit with the Paying Agent U.S. Legal Tender sufficient to pay the Redemption Price plus accrued and unpaid interest, if any, of all Notes to be redeemed on that date. If the Issuer complies with the preceding paragraph, then, unless the Issuer defaults in the payment of such Redemption Price plus accrued interest, if any, interest on the Notes to be redeemed will cease to accrue on and after the applicable Redemption Date, whether or not such Notes are presented for payment. SECTION 3.06. NOTES REDEEMED IN PART. If any Note is to be redeemed in part only, the notice of redemption that relates to such Note shall state the portion of the principal amount thereof to be redeemed. A new Note or Notes in principal amount equal to the unredeemed portion of the original Note or Notes shall be issued in the name of the Holder thereof upon surrender and cancellation of the original Note or Notes.

SECTION 4.04. PAYMENT OF TAXES.

SECTION 4.11. LIMITATIONS ON ASSET SALES. (a) The Issuer will not, and will not permit any Restricted Subsidiary to, directly or indirectly, consummate any Asset Sale unless: (1) the Issuer or such Restricted Subsidiary receives consideration at the time of such Asset Sale at least equal to the Fair Market Value of the assets included in such Asset Sale; and (2) at least 75% of the total consideration received in such Asset Sale consists of cash or Cash Equivalents. (b) For purposes of clause (2) of Section 4.11(a), the following shall be deemed to be cash: (1) the amount (without duplication) of any Indebtedness of the Issuer or such Restricted Subsidiary that is expressly assumed by the transferee in such Asset Sale and with respect to which the Issuer or such Restricted Subsidiary, as the case may be, is released by the holder of such Indebtedness; (2) the amount of any obligations received from such transferee that are within 90 days converted by the Issuer or such Restricted Subsidiary to cash (to the extent of the cash actually so received); -47- <Page> (3) the Fair Market Value of (i) any assets (other than securities) received by the Issuer or any Restricted Subsidiary to be used by it in the Permitted Business, (ii) Equity Interests in a Person that is a Restricted Subsidiary or in a Person engaged in a Permitted Business that shall become a Restricted Subsidiary immediately upon the acquisition of such Person by the Issuer or (iii) a combination of (i) and (ii); and (4) the Fair Market Value of any Equity Interests for which the Issuer or such Restricted Subsidiary has a contractual right to require the registration of such Equity Interests under the Securities Act or the applicable securities laws of the jurisdiction in which such Securities are listed on a Major Foreign Exchange ("DESIGNATED NON-CASH CONSIDERATION"); PROVIDED, HOWEVER, that no consideration received in an Asset Sale will constitute Designated Non-Cash Consideration if the classification of such consideration as Designated Non-Cash Consideration would cause the aggregate amount of all such Designated Non-Cash Consideration outstanding at that time to exceed 2.5% of Consolidated Total Assets. (c) If at any time any non-cash consideration received by the Issuer or any Restricted Subsidiary of the Issuer, as the case may be, in connection with any Asset Sale is repaid or converted into or sold or otherwise disposed of for cash (other than interest received with respect to any such non-cash consideration), then the date of such repayment, conversion or disposition shall be deemed to constitute the date of an Asset Sale hereunder and the Net Available Proceeds thereof shall be applied in accordance with this Section 4.11.

(e) The amount of Net Available Proceeds not applied or invested as provided in this paragraph will constitute "EXCESS PROCEEDS." The Issuer or such Restricted Subsidiary may repay Senior Debt or Guarantor Senior Debt under a revolving credit facility during the 360 days following the consummation of such Asset Sale without effecting a permanent reduction in the availability under such revolving credit facility, pending application of such proceeds pursuant to clause (1), (2) or (3) of Section 4.11(d) or their use as Excess Proceeds in accordance with the next paragraph, and such repayment shall not be considered an application of Net Available Proceeds for purposes of this paragraph; PROVIDED, HOWEVER, that, if such Net Available Proceeds are not applied after 360 days for any purpose other than the repayment of a revolving credit facility, a permanent reduction in the availability under such revolving credit facility shall then be required. -48- <Page> (f) When the aggregate amount of Excess Proceeds equals or exceeds $10.0 million, the Issuer will be required to make an offer to purchase from all Holders and, if applicable, redeem (or make an offer to do so) any Pari Passu Indebtedness of the Issuer the provisions of which require the Issuer to redeem such Indebtedness with the proceeds from any Asset Sales (or offer to do so), in an aggregate principal amount of Notes and such Pari Passu Indebtedness equal to the amount of such Excess Proceeds as follows: (1) the Issuer will (a) make an offer to purchase (a "NET PROCEEDS OFFER") to all Holders in accordance with the procedures set forth in this Indenture, and (b) redeem (or make an offer to do so) any such other Pari Passu Indebtedness, PRO RATA in proportion to the respective principal amounts of the Notes and such other Pari Passu Indebtedness required to be redeemed, the maximum principal amount of Notes and Pari Passu Indebtedness that may be redeemed out of the amount (the "PAYMENT AMOUNT") of such Excess Proceeds; (2) the offer price for the Notes will be payable in cash in an amount equal to 100% of the principal amount of the Notes tendered pursuant to a Net Proceeds Offer, plus accrued and unpaid interest thereon, if any, to the date such Net Proceeds Offer is consummated (the "OFFERED PRICE"), in accordance with the procedures set forth in this Indenture and the redemption price for such Pari Passu Indebtedness (the "PARI PASSU INDEBTEDNESS PRICE") shall be as set forth in the related documentation governing such Indebtedness; (3) if the aggregate Offered Price of Notes validly tendered and not withdrawn by Holders thereof exceeds the PRO RATA portion of the Payment Amount allocable to the Notes, Notes to be purchased will be selected on a PRO RATA basis; and (4) upon completion of such Net Proceeds Offer in accordance with the foregoing provisions, the amount of Excess Proceeds with respect to which such Net Proceeds Offer was made shall be deemed to be zero. (g) To the extent that the sum of the aggregate Offered Price of Notes tendered pursuant to a Net Proceeds Offer and the aggregate Pari Passu Indebtedness Price paid to the holders of such Pari Passu Indebtedness is less than the Payment Amount relating thereto (such shortfall constituting a "NET PROCEEDS DEFICIENCY"), the Issuer may use the Net Proceeds Deficiency, or a portion thereof, for general corporate purposes, subject to the provisions of this Indenture. (h) Upon the commencement of a Net Proceeds Offer, the Issuer shall send or cause to be sent, by first class mail, a notice to the Trustee and to each Holder at its registered address. The notice shall contain all instructions and materials necessary to enable such Holder to tender Notes pursuant to the Net Proceeds Offer. Any Net Proceeds Offer shall be made to all Holders. The notice, which shall govern the terms of the Net Proceeds Offer, shall state: (1) that the Net Proceeds Offer is being made pursuant to this Section 4.11; (2) the Payment Amount, the Offered Price, and the date on which Notes tendered and accepted for payment shall be purchased, which date shall be at least 30 days and not later than 60 days from the date such notices is mailed (the "NET PROCEEDS PAYMENT DATE"); (3) that any Notes not tendered or accepted for payment shall continue to accrue interest; -49- <Page> (4) that, unless the Issuer defaults in making such payment, any Notes accepted for payment pursuant to the Net Proceeds Offer shall cease to accrue interest on and after the Net Proceeds Payment Date; (5) that Holders electing to have any Notes purchased pursuant to any Net Proceeds Offer shall be required to surrender the Notes, 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 Issuer, a depository, if appointed by the Issuer, or the Paying Agent at the address specified in the notice at least three days before the Net Proceeds Payment Date; (6) that Holders shall be entitled to withdraw their election if the Issuer, the Depository or the Paying Agent, as the case may be, receives, not later than the Net Proceeds Payment Date, a notice 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 principal amount of Notes surrendered by Holders exceeds the Payment Amount, the Issuer shall select the Notes to be purchased on a PRO RATA basis (with such adjustments as may be deemed appropriate by the Issuer so that only Notes in denominations of $1,000, or integral multiples 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). (i) On the Net Proceeds Payment Date, the Issuer shall, to the extent lawful: (1) accept for payment all Notes or portions thereof properly tendered pursuant to the Net Proceeds Offer, subject to pro ration if the aggregate Notes tendered exceed the Payment Amount allocable to the Notes; (2) deposit with the Paying Agent U.S. Legal Tender equal to the lesser of the Payment Amount allocable to the Notes and the amount sufficient to pay the Offered Price in respect of all Notes or portions thereof so tendered; and (3) deliver or cause to be delivered to the Trustee the Notes so accepted together with an Officers' Certificate stating the aggregate principal amount of Notes or portions thereof being repurchased by the Issuer. The Issuer shall publicly announce the results of the Net Proceeds Offer on or as soon as practicable after the Net Proceeds Payment Date. (j) The Paying Agent shall promptly mail to each Holder of Notes so tendered the Offered Price for such Notes, and the Trustee shall promptly authenticate pursuant to an Authentication Order and mail (or cause to be transferred by book-entry) to each Holder a new Note equal in principal amount to any unrepurchased portion of the Notes surrendered, if any; PROVIDED, HOWEVER, that each such new Note shall be in principal amount of $1,000 or an integral multiple thereof. However, if the Net Proceeds Payment Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest shall be paid to the Person in whose name a Note is registered at the close of business on such record date, and no additional interest shall be payable to Holders who tender Notes pursuant to the Net Proceeds Offer. (k) The Issuer will comply with applicable tender offer rules, including the requirements of Rule 14e-1 under the Exchange Act and any other applicable laws and regulations in connection with the purchase of Notes pursuant to a Net Proceeds Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.11, the Issuer shall comply with -50- <Page> the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.11 by virtue of this compliance.

SECTION 4.14. ADDITIONAL NOTE GUARANTEES. (a) If, after the Issue Date, (a) the Issuer or any Restricted Subsidiary shall acquire or create a Domestic Subsidiary that guarantees any Indebtedness or other Obligation under the Credit Agreement (other than a Subsidiary that has been designated an Unrestricted Subsidiary), (b) any Unrestricted Subsidiary that is a Domestic Subsidiary that guarantees any Indebtedness or other Obligation under the Credit Agreement is redesignated a Restricted Subsidiary or (c) if the proviso in the definition of "Domestic Subsidiary" shall cease to apply whereupon Morpheus Acquisition LLC shall become a Domestic Subsidiary, then, in each such case, the Issuer shall cause such Restricted Subsidiary to: (1) execute and deliver to the Trustee (a) a supplemental indenture in form and substance satisfactory to the Trustee pursuant to which such Restricted Subsidiary shall unconditionally guarantee all of the Issuer's obligations under the Notes and this Indenture and (b) a notation of guarantee in respect of its Note Guarantee; and (2) deliver to the Trustee one or more opinions of counsel that such supplemental indenture (a) has been duly authorized, executed and delivered by such Restricted Subsidiary and (b) constitutes a valid and legally binding obligation of such Restricted Subsidiary in accordance with its terms.

(b) For purposes of Section 4.15(a), no Indebtedness will be deemed to be subordinated in right of payment to any other Indebtedness of the Issuer or any Restricted Subsidiary solely by virtue of being unsecured or by virtue of the fact that the holders of such Indebtedness have entered into intercreditor agreements or other arrangements giving one or more of such holders priority over the other holders in the collateral held by them. SECTION 4.16. REPORTS TO HOLDERS. (a) Whether or not required by the SEC, so long as any Notes are outstanding, the Issuer will furnish to the Holders of Notes, or file electronically with the SEC through the SEC's Electronic Data Gathering, Analysis and Retrieval System (or any successor system), within the time periods applicable to the Issuer under Section 13(a) or 15(d) of the Exchange Act: (1) all quarterly and annual financial information that would be required to be contained in a filing with the SEC on Forms 10-Q and 10-K if the Issuer were required to file these Forms, including a "Management's Discussion and Analysis of Financial Condition and Results of Operations" and, with respect to the annual information only, a report on the annual financial statements by the Issuer's certified independent accountants; and (2) all current reports that would be required to be filed with the SEC on Form 8-K if the Issuer were required to file these reports.

(c) If, at any time, any Unrestricted Subsidiary fails to meet the requirements of Section 4.17(a) and (b) as an Unrestricted Subsidiary, it shall thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of the Subsidiary and any Liens on assets of such Subsidiary shall be deemed to be incurred by a Restricted Subsidiary as of the date and, if the Indebtedness is not permitted to be incurred under Section 4.08 or the Lien is not permitted under Section 4.10, the Issuer shall be in default of the applicable covenant.

SECTION 6.02. ACCELERATION. (a) If an Event of Default specified in clause (7) or (8) of Section 6.01 with respect to the Issuer occurs, all outstanding Notes shall become due and payable without any further action or notice. If an Event of Default (other than an Event of Default specified in clause (7) or (8) of Section 6.01 with respect to the Issuer) shall have occurred and be continuing under this Indenture, the Trustee, by written notice to the Issuer, or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding by written notice to the Issuer and the Trustee, may declare all amounts owing under the Notes to be due and payable immediately. Upon such declaration of acceleration, the aggregate principal of and accrued and unpaid interest on the outstanding Notes shall become due and payable (a) if there is any Designated Senior Debt outstanding at such time, with respect to any acceleration arising out of any event of default other than a payment default, upon the earlier of (x) the date which is five (5) business days after receipt by the Representatives of a notice such acceleration or (y) the date of acceleration of any Designated Senior Debt and (b) if otherwise, immediately; PROVIDED, HOWEVER, that after such acceleration, but before a judgment or decree based on acceleration, the Holders of a majority in aggregate principal amount of such outstanding Notes may rescind and annul such acceleration: (1) if the rescission would not conflict with any judgment or decree; (2) if all existing Defaults have been cured or waived except nonpayment of principal and interest that has become due solely because of this acceleration; (3) to the extent the payment of such interest is lawful, interest on overdue installments of interest and overdue principal, which has become due otherwise than by such declaration of acceleration, has been paid; (4) if the Issuer has paid to the Trustee its reasonable compensation and reimbursed the Trustee of its expenses, disbursements and advances; and (5) in the event of a cure or waiver of a Default of the type set forth in Section 6.01(7) or (8), the Trustee shall have received an Officers' Certificate and an Opinion of Counsel that such Default has been cured or waived.

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 in exercising any right or remedy accruing upon a Default shall not impair the right or remedy or constitute a -60- <Page> waiver of or acquiescence in the Default. No remedy is exclusive of any other remedy. All available remedies are cumulative to the extent permitted by law. SECTION 6.04. WAIVER OF PAST DEFAULTS. Subject to Sections 2.09, 6.07 and 9.02, the Holders of a majority in principal amount of the outstanding Notes (which may include consents obtained in connection with a tender offer or exchange offer of Notes) by notice to the Trustee may waive an existing Default and its consequences, except a Default in the payment of principal of, or interest on, any Note as specified in Section 6.01(1) or (2).

(a) The Holders of not less than a majority in principal amount of the outstanding Notes may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on it. Subject to Section 7.01, however, the Trustee may refuse to follow any direction that conflicts with any law or this Indenture, that the Trustee determines may be unduly prejudicial to the rights of another Holder, or that may involve the Trustee in personal liability; PROVIDED, HOWEVER, that the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. (b) In the event the Trustee takes any action or follows any direction pursuant to this Indenture, the Trustee shall be entitled to indemnification against any loss or expense caused by taking such action or following such direction. SECTION 6.06. LIMITATION ON SUITS. (a) No Holder will have any right to institute any proceeding with respect to the Indenture or for any remedy thereunder, unless the Trustee: (1) has failed to act for a period of 60 days after receiving written notice of a continuing Event of Default by such Holder and a request to act by Holders of at least 25% in aggregate principal amount of Notes outstanding; (2) has been offered indemnity satisfactory to it in its reasonable judgment; and (3) has not received from the Holders of a majority in aggregate principal amount of the outstanding Notes a direction inconsistent with such request.

(c) A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over such other Holder. -61- <Page> SECTION 6.07. RIGHTS OF HOLDERS TO RECEIVE PAYMENT. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of, and interest on, a Note, on or after the respective due dates therefor, 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 the Holder. SECTION 6.08. COLLECTION SUIT BY TRUSTEE. If a Default in payment of principal or interest specified in Section 6.01(1) or (2) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Issuer or any other obligor on the Notes for the whole amount of principal and accrued interest and fees remaining unpaid, together with interest on overdue principal and, to the extent that payment of such interest is lawful, interest on overdue installments of interest, in each case at the rate PER ANNUM borne by the Notes 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 may 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 compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relating to the Issuer, their creditors or their property and shall be entitled and empowered to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same, and any Custodian in any such judicial proceedings 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 agent and counsel, and any other amounts due the Trustee under Section 7.07. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. The Trustee shall be entitled to participate as a member of any official committee of creditors in the matters as it deems necessary or advisable. SECTION 6.10. PRIORITIES. If the Trustee collects any money or property pursuant to this Article Six, it shall pay out the money or property in the following order: FIRST: to the Trustee for amounts due under Section 7.07; SECOND: to Holders for interest accrued on the Notes, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for interest; THIRD: to Holders for principal amounts due and unpaid on the Notes, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal; and -62- <Page> FOURTH: to the Issuer or, if applicable, the Guarantors, as their respective interests may appear. The Trustee, upon prior notice to the Issuer, may fix a record date and payment date for any payment to Holders 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 Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys' fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07, or a suit by a Holder or Holders of more than 10% in principal amount of the outstanding Notes. ARTICLE SEVEN TRUSTEE SECTION 7.01. DUTIES OF TRUSTEE.

The Trustee also shall comply with Trust Indenture Act Sections 313(b), 313(c) and 313(d). A copy of each report at the time of its mailing to Holders shall be mailed to the Issuer and filed with the SEC and each securities exchange, if any, on which the Notes are listed. The Issuer shall notify the Trustee if the Notes become listed on any securities exchange or of any delisting thereof and the Trustee shall comply with Trust Indenture Act Section 313(d). SECTION 7.07. COMPENSATION AND INDEMNITY.

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Issuer shall notify each Holder of such event and 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 Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Issuer. A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuer. Immediately after that, the retiring Trustee shall transfer, after payment of all sums then owing to the Trustee pursuant to Section 7.07, all property held by it as Trustee to the successor Trustee, subject to the Lien provided in Section 7.07, 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.

If the Trustee fails to comply with Section 7.10, any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Issuer's obligations under Section 7.07 shall continue for the benefit of the retiring Trustee. SECTION 7.09. SUCCESSOR TRUSTEE BY MERGER, ETC. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the resulting, surviving or transferee corporation without any further act shall, if such resulting, surviving or transferee corporation is otherwise eligible hereunder, be the successor Trustee; PROVIDED, HOWEVER, that such corporation shall be otherwise qualified and eligible under this Article Seven.

The provisions of Trust Indenture Act Section 310 shall apply to the Issuer and any other obligor of the Notes. SECTION 7.11. PREFERENTIAL COLLECTION OF CLAIMS AGAINST THE ISSUER.

In the case of clause (2) of this Section 8.01, and subject to the next sentence and notwithstanding the foregoing paragraph, the Issuer's obligations in Sections 2.05, 2.06, 2.07, 2.08, 4.01, 4.02, 4.03 (as to legal existence of the Issuer only), 7.07, 8.05 and 8.06 shall survive until the Notes are no longer outstanding pursuant to the last paragraph of Section 2.08. After the Notes are no longer outstanding, the Issuer's obligations in Sections 7.07, 8.05 and 8.06 shall survive. After such delivery or irrevocable deposit, the Trustee upon request shall acknowledge in writing the discharge of the Issuer's obligations under the Notes and this Indenture except for those surviving obligations specified above.

(a) The Issuer may, at its option and at any time, elect to have either paragraph (b) or (c) below be applied to all outstanding Notes upon compliance with the conditions set forth in Section 8.03. (b) Upon the Issuer's exercise under Section 8.02(a) hereof of the option applicable to this Section 8.02(b), the Issuer and the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.03, be deemed to have been discharged from their obligations with respect to all outstanding Notes on the date the conditions set forth below are satisfied (hereinafter, "LEGAL DEFEASANCE"). For this purpose, Legal Defeasance means that the Issuer and the Guarantors shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes and the Note Guarantees, which shall thereafter be deemed to be "outstanding" only for the purposes of Section 8.04 hereof and the other Sections of this Indenture referred to in (i) and (ii) below, and to have satisfied all its other obligations under such Notes and this Indenture and the Guarantors shall be deemed to have satisfied all of their obligations under the Note Guarantees and this Indenture (and the Trustee, on demand of and at the expense of the Issuer, shall execute proper instruments acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder: (i) the rights of Holders of outstanding Notes to receive, solely from the trust fund described in Section 8.04 hereof, and as more fully set forth in such Section 8.04, payments in respect of the principal of, premium, if any, and interest on such Notes when such payments are due; -69- <Page> (ii) the Issuer's obligations with respect to such Notes under Article Two and Section 4.02 hereof; (iii) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Issuer's obligations in connection therewith; and (iv) the provisions of this Article Eight applicable to Legal Defeasance.

(c) Upon the Issuer's exercise under paragraph (a) hereof of the option applicable to this paragraph (c), the Issuer and the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.03 hereof, be released from their respective obligations under the covenants contained in Sections 4.03 (other than with respect to the legal existence of the Issuer), 4.04, 4.05, and 4.07 through 4.20, clause (3) of Section 5.01(a) and Article 11 hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.03 are satisfied (hereinafter, "COVENANT DEFEASANCE"), and the Notes shall thereafter be deemed not "outstanding" for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed "outstanding" for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Issuer and the Guarantors 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 an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon the Issuer's exercise under paragraph (a) hereof of the option applicable to this paragraph (c), subject to the satisfaction of the conditions set forth in Section 8.03 hereof, clauses (3), (4), (5), (6) and (9) of Section 6.01 hereof shall not constitute Events of Default.

SECTION 8.05. REPAYMENT TO THE ISSUER. The Trustee and the Paying Agent shall pay to the Issuer upon request any money held by them for the payment of principal or interest that remains unclaimed for two years; PROVIDED, HOWEVER, that the Trustee or such Paying Agent, before being required to make any payment, may at the expense of the Issuer cause to be published once in a newspaper of general circulation in the City of New York or mail to each Holder entitled to such money notice that such money remains unclaimed and that after a date specified therein which shall be at least 30 days from the date of such publication or mailing any unclaimed balance of such money then remaining will be repaid to the Issuer.

If the Trustee or Paying Agent is unable to apply any U.S. Legal Tender and U.S. Government Obligations in accordance with this Article Eight by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, or if the funds deposited with the Trustee to effect Covenant Defeasance are insufficient to pay the principal of, and interest on, the Notes when due, the Issuer's obligations under this Indenture, and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to this Article Eight until such time as the Trustee or Paying Agent is permitted to apply all such U.S. Legal Tender and U.S. Government Obligations in accordance with this Article Eight; PROVIDED, HOWEVER, that if the Issuer has made any payment of interest on, or principal of, any Notes because of the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Notes to receive such payment from the U.S. Legal Tender and U.S. Government Obligations held by the Trustee or Paying Agent.

Until an amendment, waiver or supplement becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder's Note, even if notation of the consent is not made on any Note. However, any such Holder or subsequent Holder may revoke the consent as to his Note or portion of his Note by notice to the Trustee or the Issuer received before the date on which the Trustee receives an Officers' Certificate certifying that the Holders of the requisite principal amount of Notes have consented (and not theretofore revoked such consent) to the amendment, supplement or waiver. The Issuer may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver, which record date shall -74- <Page> be at least 30 days prior to the first solicitation of such consent. If a record date is fixed, then notwithstanding the last sentence of the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to revoke any consent previously given, whether or not such Persons continue to be Holders after such record date. No such consent shall be valid or effective for more than 90 days after such record date. The Issuer shall inform the Trustee in writing of the fixed record date if applicable. After an amendment, supplement or waiver becomes effective, it shall bind every Holder, unless it makes a change described in any of clauses (1) through (10) of Section 9.02(b), in which case, the amendment, supplement or waiver shall bind only each Holder of a Note who has consented to it and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder's Note; PROVIDED, HOWEVER, that any such waiver shall not impair or affect the right of any Holder to receive payment of principal of, and interest on, a Note, on or after the respective due dates therefor, or to bring suit for the enforcement of any such payment on or after such respective dates without the consent of such Holder. SECTION 9.06. NOTATION ON OR EXCHANGE OF NOTES. If an amendment, supplement or waiver changes the terms of a Note, the Issuer may require the Holder of the Note to deliver it to the Trustee. The Issuer shall provide the Trustee with an appropriate notation on the Note about the changed terms and cause the Trustee to return it to the Holder at the Issuer's expense. Alternatively, if the Issuer or the Trustee so determines, the Issuer in exchange for the Note shall issue, and the Trustee shall authenticate, a new Note that reflects the changed terms. 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 9.07. TRUSTEE TO SIGN AMENDMENTS, ETC. The Trustee shall execute any amendment, supplement or waiver authorized pursuant to this Article Nine; PROVIDED, HOWEVER, that the Trustee may, but shall not be obligated to, execute any such amendment, supplement or waiver which affects the Trustee's own rights, duties or immunities under this Indenture. The Trustee shall be entitled to receive, and shall be fully protected in relying upon, an Opinion of Counsel and an Officers' Certificate each stating that the execution of any amendment, supplement or waiver authorized pursuant to this Article Nine is authorized or permitted by this Indenture and constitutes legal, valid and binding obligations of the Issuer enforceable in accordance with its terms, subject to customary exceptions. Such Opinion of Counsel shall be at the expense of the Issuer. ARTICLE TEN SUBORDINATION OF NOTES SECTION 10.01. NOTES SUBORDINATED TO SENIOR DEBT. Anything herein to the contrary notwithstanding, each of the Issuer, for itself and its successors, and each Holder, by his or her acceptance of Notes, agrees that the payment of all Obligations owing to the Holders in respect of the Notes is subordinated, to the extent and in the manner provided in this Article Ten, to the prior payment in full of all Senior Debt (including all Obligations under the Credit Agreement) in cash, whether outstanding on the Issue Date or thereafter incurred. Notwithstanding anything in this Article Ten to the contrary, payments and distributions (A) of Permitted Junior Securities and (B) made relating to the Notes from the trust established pursuant to Article Eight shall not be so subordi- -75- <Page> nated in right of payment, so long as, with respect to (B), (i) the conditions specified in Article Eight are satisfied on the date of any deposit pursuant to said trust and (ii) such payments and distributions did not violate the provisions of this Article Ten when made. This Article Ten shall constitute a continuing offer to all Persons who become holders of, or continue to hold, Senior Debt, such provisions are made for the benefit of the holders of Senior Debt and such holders are made obligees hereunder and any one or more of them may enforce such provisions. SECTION 10.02. SUSPENSION OF PAYMENT WHEN SENIOR DEBT IS IN DEFAULT. (a) If any default occurs and is continuing in the payment when due, whether at maturity, upon any redemption, by declaration or otherwise, of any principal of, interest on, unpaid drawings for letters of credit issued in respect of, or fees with respect to, any Senior Debt (a "PAYMENT DEFAULT"), then the Issuer shall not (x) make any payment or distribution of any kind or character with respect to any Obligations on or relating to the Notes or (y) acquire any of the Notes for cash or assets or otherwise (other than, in either case, Permitted Junior Securities). (b) If any other event of default (other than a Payment Default) occurs and is continuing with respect to any Designated Senior Debt (as such event of default is defined in the instrument creating or evidencing such Designated Senior Debt) permitting the holders of such Designated Senior Debt then outstanding to accelerate the maturity thereof (a "NON-PAYMENT DEFAULT") and if the Representative for the respective issue of Designated Senior Debt (including, as applicable, the administrative agent under the Credit Agreement) gives written notice of the Non-Payment Default to the Trustee stating that such notice is a payment blockage notice (a "PAYMENT BLOCKAGE NOTICE"), then during the period (the "PAYMENT BLOCKAGE PERIOD") beginning upon the delivery of such Payment Blockage Notice and ending on the earliest of (1) the date on which all such Non-Payment Defaults are cured or waived, (2) 179 days after the date on which the applicable Payment Blockage Notice is received or (3) the date on which the Trustee receives notice from the Representative for such Designated Senior Debt rescinding the Payment Blockage Notice (unless in each case the maturity of any Designated Senior Debt has been accelerated), the Issuer shall not (x) make any payment of any kind or character with respect to any Obligations on or with respect to the Notes or (y) acquire any of the Notes for cash or assets or otherwise (other than, in either case, Permitted Junior Securities). Notwithstanding anything herein to the contrary, (x) in no event will a Payment Blockage Period extend beyond 179 days from the date the applicable Payment Blockage Notice is received by the Trustee and (y) no new Payment Blockage Notice may be delivered unless and until 360 days have elapsed since the effectiveness of the immediately prior Payment Blockage Notice. For all purposes of this Section 10.02(b), no Non-Payment Default which existed or was continuing on the date of the commencement of any Payment Blockage Period with respect to the Designated Senior Debt shall be, or be made, the basis for the commencement of a second Payment Blockage Period by the Representative of such Designated Senior Debt whether or not within a period of 360 consecutive days, unless such Non-Payment Default shall have been cured or waived for a period of not less than 90 consecutive days. Any subsequent action, or any breach of any financial covenants for a period ending after the date of commencement of such Payment Blockage Period that, in either case, would give rise to a Non-Payment Default pursuant to any provisions under which a Non-Payment Default previously existed or was continuing shall constitute a new Non-Payment Default for this purpose. (c) In the event that, notwithstanding the foregoing, any payment shall be received by the Trustee or any Holder when such payment is prohibited by the foregoing provisions of this Section 10.02, such payment shall be held in trust for the benefit of, and shall be paid over or delivered to, the holders of Senior Debt (pro rata to such holders on the basis of the respective amount of Senior Debt held by such holders) or their respective Representatives, as their respective interests may appear. The Trustee -76- <Page> shall be entitled to rely on information regarding amounts outstanding on the Senior Debt, if any, received from the holders of the Senior Debt (or their Representatives). Nothing contained in this Article Ten shall limit the right of the Trustee or the Holders of the Notes to take any action to accelerate the maturity of the Notes pursuant to Section 6.02 or to pursue any rights or remedies hereunder; PROVIDED, HOWEVER, that all Senior Debt thereafter due or declared to be due shall first be paid in full in cash or cash equivalents before the Holders are entitled to receive any payment of any kind or character with respect to Obligations on the Notes. SECTION 10.03. NOTES SUBORDINATED TO PRIOR PAYMENT OF ALL SENIOR DEBT ON DISSOLUTION, LIQUIDATION OR REORGANIZATION OF THE ISSUER. (a) Upon any payment or distribution of assets of the Issuer or any of its Subsidiaries of any kind or character, whether in cash, assets or securities, to creditors upon any total or partial liquidation, dissolution, winding-up, assignment for the benefit of creditors or marshaling of assets and liabilities of the Issuer or in a bankruptcy, reorganization, insolvency, receivership or other similar proceeding relating to the Issuer or its assets, whether voluntary or involuntary, all Obligations due on all Senior Debt (including interest accruing after the commencement of any bankruptcy or other like proceeding at the rate specified in the Credit Agreement, whether or not such interest is an allowed claim in any such proceeding) shall first be paid in full in cash, or such payment duly provided for to the satisfaction of the holders of Senior Debt, before any payment or distribution of any kind or character is made on account of any Obligations on or relating to the Notes, or for the acquisition of any of the Notes for cash or assets or otherwise. Upon any such dissolution, winding-up, liquidation, reorganization, receivership or similar proceeding, any payment or distribution of assets of the Issuer or any of its Subsidiaries of any kind or character, whether in cash, assets or securities, to which the Holders of the Notes or the Trustee under this Indenture would be entitled, except for the provisions hereof, shall be paid by the Issuer or by any receiver, trustee in bankruptcy, liquidating trustee, agent or other Person making such payment or distribution, or by the Holders or by the Trustee under this Indenture if received by them, directly to the holders of Senior Debt (PRO RATA to such holders on the basis of the respective amounts of Senior Debt held by such holders) or their respective Representatives, or to the trustee or trustees under any indenture pursuant to which any of such Senior Debt may have been issued, as their respective interests may appear, for application to the payment of Senior Debt remaining unpaid until all such Senior Debt has been paid in full in cash after giving effect to any concurrent payment, distribution or provision therefor to or for the holders of Senior Debt. (b) To the extent any payment of Senior Debt (whether by or on behalf of the Issuer, as proceeds of security or enforcement of any right of setoff or otherwise) is declared to be fraudulent or preferential, set aside or required to be paid to any receiver, trustee in bankruptcy, liquidating trustee, agent or other similar Person under any bankruptcy, insolvency, receivership, fraudulent conveyance or similar law, then, if such payment is recovered by, or paid over to, such receiver, trustee in bankruptcy, liquidating trustee, agent or other similar Person, the Senior Debt or part thereof originally intended to be satisfied shall be for purpose of this Article Ten deemed to be reinstated and outstanding as if such payment had not occurred. It is further agreed that any diminution (whether pursuant to court decree or otherwise, including without limitation for any of the reasons described in the preceding sentence) of the Issuer's obligation to make any distribution or payment pursuant to any Senior Debt, except to the extent such diminution occurs by reason of the repayment (which has not been disgorged or returned) of such Senior Debt in cash or cash equivalents, shall have no force or effect for purposes of the subordination provisions -77- <Page> contained in this Article Ten, with any turnover of payments as otherwise calculated pursuant to this Article Ten to be made as if no such diminution had occurred. (c) In the event that, notwithstanding the foregoing, any payment or distribution of assets of the Issuer of any kind or character, whether in cash, assets or securities, shall be received by any Holder when such payment or distribution is prohibited by this Section 10.03, such payment or distribution shall be held in trust for the benefit of, and shall be paid over or delivered to, the holders of Senior Debt (PRO RATA to such holders on the basis of the respective amount of Senior Debt held by such holders) or their respective Representatives, or to the trustee or trustees under any indenture pursuant to which any of such Senior Debt may have been issued, as their respective interests may appear, for application to the payment of Senior Debt remaining unpaid until all such Senior Debt has been paid in full in cash or cash equivalents, after giving effect to any concurrent payment, distribution or provision therefor to or for the holders of such Senior Debt. (d) The consolidation of the Issuer with, or the merger of the Issuer with or into, another Person or the liquidation or dissolution of the Issuer following the conveyance or transfer of all or substantially all of its assets, to another Person upon the terms and conditions provided in Article Five hereof shall not be deemed a dissolution, winding-up, liquidation or reorganization for the purposes of this Section if such other Person shall, as a part of such consolidation, merger, conveyance or transfer, assume the Issuer's obligations hereunder in accordance with Article Five hereof. SECTION 10.04. PAYMENTS MAY BE MADE ON NOTES. Nothing contained in this Article Ten or elsewhere in this Indenture shall prevent (i) the Issuer, except under the conditions described in Sections 10.02 and 10.03, from making payments at any time for the purpose of making payments of principal of, and interest on, the Notes, or from depositing with the Trustee any moneys for such payments, or (ii) in the absence of actual knowledge by the Trustee that a given payment would be prohibited by Section 10.02 or 10.03, the application by the Trustee of any moneys deposited with it for the purpose of making such payments of principal of, and interest on, the Notes to the Holders entitled thereto unless at least two Business Days prior to the date upon which such payment would otherwise become due and payable a Responsible Officer of the Trustee shall have actually received the written notice provided for in the first sentence of Section 10.02(b) or in Section 10.07; PROVIDED, HOWEVER, that, notwithstanding the foregoing, the Holders receiving any payments made in contravention of Section 10.02 and/or 10.03 (and the respective such payments) shall otherwise be subject to the provisions of Section 10.02 and Section 10.03. Notwithstanding anything to the contrary contained in this Article Ten or elsewhere in this Indenture, payments and distributions from the funds deposited pursuant to Article Eight will be permitted to be made and will not be subject to the provisions of this Article Ten so long as such funds were deposited in accordance with the provisions of Article Eight and did not violate the provisions of this Article Ten when such funds were so deposited. The Issuer shall give prompt written notice to the Trustee of any dissolution, winding-up, liquidation or reorganization of the Issuer, although any delay or failure to give any such notice shall have no effect on the subordination provisions contained herein. SECTION 10.05. HOLDERS TO BE SUBROGATED TO RIGHTS OF HOLDERS OF SENIOR DEBT. Subject to the payment in full of all Senior Debt in cash or cash equivalents, the Holders of the Notes shall be subrogated to the rights of the holders of Senior Debt to receive payments or distributions of cash, assets or securities of the Issuer applicable to the Senior Debt until the Notes shall be paid in full; and, for the purposes of such subrogation, no such payments or distributions to the holders of the Senior Debt by or on behalf of the Issuer, or by or on behalf of the Holders by virtue of this Article Ten, -78- <Page> which otherwise would have been made to the Holders shall, as between the Issuer and the Holders, be deemed to be a payment by the Issuer to or on account of the Senior Debt, it being understood that the provisions of this Article Ten are and are intended solely for the purpose of defining the relative rights of the Holders, on the one hand, and the holders of Senior Debt, on the other hand. SECTION 10.06. OBLIGATIONS OF THE ISSUER UNCONDITIONAL. Nothing contained in this Article Ten or elsewhere in this Indenture or in the Notes is intended to or shall impair, as between the Issuer, and the Holders, the obligation of the Issuer, which is absolute and unconditional, to pay to the Holders the principal of, and any interest on, the Notes as and when the same shall become due and payable in accordance with their terms, or is intended to or shall affect the relative rights of the Holders and creditors of the Issuer other than the holders of the Senior Debt, nor shall anything herein or therein prevent the Holder of any Note or the Trustee on its behalf from exercising all remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights, if any, of the holders of Senior Debt in respect of cash, assets or securities of the Issuer received upon the exercise of any such remedy. SECTION 10.07. NOTICE TO TRUSTEE. The Issuer shall give prompt written notice to the Trustee of any fact known to the Issuer which would prohibit the making of any payment to or by the Trustee in respect of the Notes pursuant to the provisions of this Article Ten, although any delay or failure to give any such notice shall have no effect on the subordination provisions contained herein. Regardless of anything to the contrary contained in this Article Ten or elsewhere in this Indenture, the Trustee shall not be charged with knowledge of the existence of any default or event of default with respect to any Senior Debt or of any other facts which would prohibit the making of any payment to or by the Trustee unless and until the Trustee shall have received notice in writing from the Issuer, or from a holder of Senior Debt or a Representative therefor and, prior to the receipt of any such written notice, the Trustee shall be entitled to assume (in the absence of actual knowledge to the contrary) that no such facts exist. The Trustee shall be entitled to rely on the delivery to it of any notice pursuant to this Section 10.07 to establish that such notice has been given by a holder of Senior Debt (or a Representative thereof). In the event that the Trustee determines in good faith that any evidence is required with respect to the right of any Person as a holder of Senior Debt to participate in any payment or distribution pursuant to this Article Ten, the Trustee may request such Person to furnish evidence to the satisfaction of the Trustee as to the amounts of Senior Debt held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such Person under this Article Ten, and if such evidence is not furnished the Trustee may defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment. SECTION 10.08. RELIANCE ON JUDICIAL ORDER OR CERTIFICATE OF LIQUIDATING AGENT. Upon any payment or distribution of assets of the Issuer referred to in this Article Ten, the Trustee, subject to the provisions of Article Seven hereof, and the Holders of the Notes shall be entitled to rely upon any order or decree made by any court of competent jurisdiction in which any insolvency, bankruptcy, receivership, dissolution, winding-up, liquidation, reorganization or similar case or proceeding is pending, or upon a certificate of the receiver, trustee in bankruptcy, liquidating trustee, assignee for the benefit of creditors, agent or other person making such payment or distribution, delivered to the Trustee or the Holders of the Notes, for the purpose of ascertaining the persons entitled to participate in such payment or distribution, the holders of the Senior Debt and other Indebtedness of the Issuer, the -79- <Page> amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article Ten. SECTION 10.09. TRUSTEE'S RELATION TO SENIOR DEBT. The Trustee and any agent of the Issuer or the Trustee shall be entitled to all the rights set forth in this Article Ten with respect to any Senior Debt which may at any time be held by it in its individual or any other capacity to the same extent as any other holder of Senior Debt and nothing in this Indenture shall deprive the Trustee or any such agent of any of its rights as such holder. With respect to the holders of Senior Debt, the Trustee undertakes to perform or to observe only such of its covenants and obligations as are specifically set forth in this Article Ten, and no implied covenants or obligations with respect to the holders of Senior Debt shall be read into this Indenture against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Debt. Whenever a distribution is to be made or a notice given to holders or owners of Senior Debt, the distribution may be made and the notice may be given to their Representative, if any. SECTION 10.10. SUBORDINATION RIGHTS NOT IMPAIRED BY ACTS OR OMISSIONS OF THE ISSUER OR HOLDERS OF SENIOR DEBT. No right of any present or future holders of any Senior Debt to enforce subordination as provided herein shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Issuer or by any act or failure to act, in good faith, by any such holder, or by any noncompliance by the Issuer with the terms of this Indenture, regardless of any knowledge thereof, which any such holder may have or otherwise be charged with. Without in any way limiting the generality of the foregoing paragraph, the holders of Senior Debt may, at any time and from time to time, without the consent of or notice to the Trustee, without incurring responsibility to the Trustee or the Holders of the Notes and without impairing or releasing the subordination provided in this Article Ten or the obligations hereunder of the Holders of the Notes to the holders of the Senior Debt, do any one or more of the following: (i) change the manner, place or terms of payment or extend the time of payment of, or renew or alter, Senior Debt, or otherwise amend or supplement in any manner Senior Debt, or any instrument evidencing the same or any agreement under which Senior Debt is outstanding; (ii) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing Senior Debt; (iii) release any Person liable in any manner for the payment or collection of Senior Debt; and (iv) exercise or refrain from exercising any rights against the Issuer and any other Person. SECTION 10.11. HOLDERS AUTHORIZE TRUSTEE TO EFFECTUATE SUBORDINATION OF NOTES. Each Holder of the Notes by its acceptance of them authorizes and expressly directs the Trustee on its behalf to take such action as may be necessary or appropriate to effectuate, as between the holders of Senior Debt and the Holders of the Notes, the subordination provided in this Article Ten, and appoints the Trustee its attorney-in-fact for such purposes, including, in the event of any dissolution, winding-up, liquidation or reorganization of the Issuer (whether in bankruptcy, insolvency, receivership, reorganization or similar proceedings or upon an assignment for the benefit of credits or otherwise) tending towards liquidation of the business and assets of the Issuer, the filing of a claim for the unpaid balance of its Notes and accrued interest in the form required in those proceedings. -80- <Page> If the Trustee does not file a proper claim or proof of debt in the form required in such proceeding prior to 30 days before the expiration of the time to file such claim or claims, then the holders of the Senior Debt or their Representative are or is hereby authorized to have the right to file and are or is hereby authorized to file an appropriate claim for and on behalf of the Holders of said Notes. Nothing herein contained shall be deemed to authorize the Trustee or the holders of Senior Debt or their Representative to authorize, consent to, accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee or the holders of Senior Debt or their Representative to vote in respect of the claim of any Holder in any such proceeding. SECTION 10.12. THIS ARTICLE TEN NOT TO PREVENT EVENTS OF DEFAULT. The failure to make a payment on account of principal of, or interest on, the Notes by reason of any provision of this Article Ten will not be construed as preventing the occurrence of an Event of Default. SECTION 10.13. TRUSTEE'S COMPENSATION NOT PREJUDICED. Nothing in this Article Ten will apply to amounts due to the Trustee (other than payments of Obligations owing to Holders in respect of the Notes) pursuant to other Sections of this Indenture. ARTICLE ELEVEN NOTE GUARANTEE SECTION 11.01. UNCONDITIONAL GUARANTEE. Subject to the provisions of this Article Eleven, each of the Guarantors hereby, jointly and severally, unconditionally and irrevocably 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 Issuer or any other Guarantors to the Holders or the Trustee hereunder or thereunder: (a) (x) the due and punctual payment of the principal of, premium, if any, and interest on the Notes when and as the same shall become due and payable, whether at maturity, upon redemption or repurchase, by acceleration or otherwise, (y) the due and punctual payment of interest on the overdue principal and (to the extent permitted by law) interest, if any, on the Notes and (z) the due and punctual payment and performance of all other obligations of the Issuer and all other obligations of the other Guarantors (including under the Note Guarantees), in each case, to the Holders or the Trustee hereunder or thereunder (including amounts due the Trustee under Section 7.07 hereof), all in accordance with the terms hereof and thereof (collectively, the "GUARANTEE OBLIGATIONS"); and (b) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, the due and punctual payment and performance of Guarantee Obligations in accordance with the terms of the extension or renewal, whether at maturity, upon redemption or repurchase, by acceleration or otherwise. Failing payment when due of any amount so guaranteed, or failing performance of any other obligation of the Issuer to the Holders under this Indenture or under the Notes, for whatever reason, each Guarantor shall be obligated to pay, or to perform or cause the performance of, the same immediately. A Default under this Indenture or the Notes shall constitute an event of default under the Note Guarantees, and shall entitle the Holders of Notes to accelerate the obligations of the Guarantors thereunder in the same manner and to the same extent as the obligations of the Issuer. -81- <Page> Each of the Guarantors hereby agrees that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, any release of any other Guarantor, the recovery of any judgment against the Issuer, any action to enforce the same, whether or not a Note Guarantee is affixed to any particular Note, or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor. Each of the Guarantors hereby waives the benefit of diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuer, any right to require a proceeding first against the Issuer, protest, notice and all demands whatsoever and covenants that its Note Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes, this Indenture and its Note Guarantee. Each Note Guarantee is a guarantee of payment and not of collection. If any Holder or the Trustee is required by any court or otherwise to return to the Issuer or to any Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to the Issuer or such Guarantor, any amount paid by the Issuer or such Guarantor to the Trustee or such Holder, each Note Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Guarantor further agrees that, as between it, on the one hand, and the Holders of Notes and the Trustee, on the other hand, (a) subject to this Article Eleven, the maturity of the obligations guaranteed hereby may be accelerated as provided in Article Six for the purposes of the Note Guarantees, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (b) in the event of any acceleration of such obligations as provided in Article Six, such obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantors for the purpose of the Note Guarantees. SECTION 11.02. SUBORDINATION OF NOTE GUARANTEE. The obligations of each Guarantor under its Note Guarantee pursuant to this Article Eleven shall be junior and subordinated to the prior payment in full of the Guarantor Senior Debt of such Guarantor, whether outstanding on the Issue Date or thereafter incurred, in cash on the same basis as the Notes are junior and subordinated to Senior Debt of the Issuer. For the purposes of the foregoing sentence, the Trustee and the Holders shall have the right to receive and/or retain payments by any of the Guarantors only at such times as they may receive and/or retain payments in respect of the Notes pursuant to this Indenture, including Article Ten. In addition to the foregoing provisions of this Section 11.02, all of the covenants, obligations and agreements contained in Article Ten (together with related definitions) shall be deemed incorporated in this Section 11.02, MUTATIS MUTANDIS, as if references to the Issuer therein are references to each Guarantor herein and references to Senior Debt therein are references to the Guarantor Senior Debt of such Guarantor herein. SECTION 11.03. 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 Note 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, foreign or state law to the extent applicable to any Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor under its Note Guarantee and this Article Eleven shall be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Guarantor (including any guarantee under the Credit Agreement) 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 Eleven, result in the obligations of such Guarantor under its Note Guarantee not -82- <Page> constituting a fraudulent transfer or conveyance. Each Guarantor that makes a payment for distribution under its Note Guarantee is entitled to a contribution from each other Guarantor in a PRO RATA amount based on the adjusted net assets of each Guarantor. SECTION 11.04. EXECUTION AND DELIVERY OF NOTE GUARANTEE. To further evidence its Note Guarantee set forth in Section 11.01, each Guarantor hereby agrees that a notation of such Note Guarantee, substantially in the form of EXHIBIT E hereto, shall be endorsed on each Note authenticated and delivered by the Trustee. Such Note Guarantee shall be executed on behalf of each Guarantor by either manual or facsimile signature of one Officer or other person duly authorized by all necessary corporate action of each Guarantor who shall have been duly authorized to so execute by all requisite corporate action. The validity and enforceability of any Note Guarantee shall not be affected by the fact that it is not affixed to any particular Note. Each of the Guarantors hereby agrees that its Note Guarantee set forth in Section 11.01 shall remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Note Guarantee. If an Officer of a Guarantor whose signature is on this Indenture or a Note Guarantee no longer holds that office at the time the Trustee authenticates the Note on which such Note Guarantee is endorsed or at any time thereafter, such Guarantor's Note Guarantee of such Note shall nevertheless be valid. The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of any Note Guarantee set forth in this Indenture on behalf of each Guarantor. SECTION 11.05. RELEASE OF A GUARANTOR. A Guarantor shall be released from its obligations under its Note Guarantee and its obligations under this Indenture and the Registration Rights Agreement: (1) in the event of a sale or other disposition of all or substantially all of the assets of such Guarantor, by way of merger, consolidation or otherwise, or a sale or other disposition of all of the Equity Interests of such Guarantor then held by the Issuer and the Restricted Subsidiaries; (2) if such Guarantor is designated as an Unrestricted Subsidiary or otherwise ceases to be a Restricted Subsidiary, in each case in accordance with the provisions of this Indenture, upon effectiveness of such designation or when it first ceases to be a Restricted Subsidiary, respectively; or (3) if such Guarantor shall not guarantee any Indebtedness or other Obligation under the Credit Agreement (other than if such Guarantor no longer guarantees any Indebtedness or other Obligation under the Credit Agreement as a result of payment under any guarantee of any such Indebtedness or other Obligation by such Guarantor); PROVIDED, HOWEVER, that a Guarantor shall not be permitted to be released from its Note Guarantee if it is an obligor with respect to any Indebtedness or other Obligation that would not, under Section 4.08, be permitted to be incurred by a Restricted Subsidiary that is not a Guarantor. The Trustee shall execute an appropriate instrument prepared by the Issuer evidencing the release of a Guarantor from its obligations under its Note Guarantee upon receipt of a request by the Is- -83- <Page> suer or such Guarantor accompanied by an Officers' Certificate and an Opinion of Counsel certifying as to the compliance with this Section 11.05; PROVIDED, HOWEVER, that the legal counsel delivering such Opinion of Counsel may rely as to matters of fact on one or more Officers' Certificates of the Issuer. Except as set forth in Articles Four and Five and this Section 11.05, nothing contained in this Indenture or in any of the Notes shall prevent any consolidation or merger of a Guarantor with or into the Issuer (in which case such Guarantor shall no longer be a Guarantor) or another Guarantor or shall prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Issuer or another Guarantor. SECTION 11.06. WAIVER OF SUBROGATION. Until this Indenture is discharged and all of the Notes are discharged and paid in full, each Guarantor hereby irrevocably waives and agrees not to exercise any claim or other rights which it may now or hereafter acquire against the Issuer that arise from the existence, payment, performance or enforcement of the Issuer's obligations under the Notes or this Indenture and such Guarantor's obligations under its Note Guarantee and this Indenture, in any such instance including, without limitation, any right of subrogation, reimbursement, exoneration, contribution, indemnification, and any right to participate in any claim or remedy of the Holders against the Issuer, whether or not such claim, remedy or right arises in equity, or under contract, statute or common law, including, without limitation, the right to take or receive from the Issuer, directly or indirectly, in cash or other assets or by set-off or in any other manner, payment or security on account of such claim or other rights. If any amount shall be paid to any Guarantor in violation of the preceding sentence and any amounts owing to the Trustee or the Holders of Notes under the Notes, this Indenture, or any other document or instrument delivered under or in connection with such agreements or instruments, shall not have been paid in full, such amount shall have been deemed to have been paid to such Guarantor for the benefit of, and held in trust for the benefit of, the Trustee or the Holders and shall forthwith be paid to the Trustee for the benefit of itself or such Holders to be credited and applied to the obligations in favor of the Trustee or the Holders, as the case may be, whether matured or unmatured, in accordance with the terms of this Indenture. Each Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by this Indenture and that the waiver set forth in this Section 11.06 is knowingly made in contemplation of such benefits.

The obligations of each Guarantor hereunder are and shall be absolute and unconditional and any monies or amounts expressed to be owing or payable by each Guarantor hereunder which may -84- <Page> not be recoverable from such Guarantor on the basis of a Guarantee shall be recoverable from such Guarantor as a primary obligor and principal debtor in respect thereof. SECTION 11.10. GUARANTEE OBLIGATIONS CONTINUING. The obligations of each Guarantor hereunder shall be continuing and shall remain in full force and effect until all such obligations have been paid and satisfied in full. Each Guarantor agrees with the Trustee that it will from time to time deliver to the Trustee suitable acknowledgments of this continued liability hereunder and under any other instrument or instruments in such form as counsel to the Trustee may advise and as will prevent any action brought against it in respect of any default hereunder being barred by any statute of limitations now or hereafter in force and, in the event of the failure of a Guarantor so to do, it hereby irrevocably appoints the Trustee the attorney and agent of such Guarantor to make, execute and deliver such written acknowledgment or acknowledgments or other instruments as may from time to time become necessary or advisable, in the judgment of the Trustee on the advice of counsel, to fully maintain and keep in force the liability of such Guarantor hereunder. SECTION 11.11. GUARANTEE OBLIGATIONS NOT REDUCED.

SECTION 11.12. GUARANTEE OBLIGATIONS REINSTATED. The obligations of each Guarantor hereunder shall continue to be effective or shall be reinstated, as the case may be, if at any time any payment which would otherwise have reduced the obligations of any Guarantor hereunder (whether such payment shall have been made by or on behalf of the Issuer or by or on behalf of a Guarantor) is rescinded or reclaimed from any of the Holders upon the insolvency, bankruptcy, liquidation or reorganization of the Issuer or any Guarantor or otherwise, all as though such payment had not been made. If demand for, or acceleration of the time for, payment by the Issuer or any other Guarantor is stayed upon the insolvency, bankruptcy, liquidation or reorganization of the Issuer or such Guarantor, all such Indebtedness otherwise subject to demand for payment or acceleration shall nonetheless be payable by each Guarantor as provided herein. SECTION 11.13. GUARANTEE OBLIGATIONS NOT AFFECTED.

Without notice to or consent of any Holder, the parties thereto may amend or supplement the Indenture and the Notes to, among other things, cure any ambiguity, defect or inconsistency in the Indenture, provide for uncertificated Notes in addition to or in place of certificated Notes, comply with any requirements of the SEC in connection with the qualification of the Indenture under the Trust Indenture Act, or make any change that does not materially adversely affect the rights of any Holder. SECTION 13. DEFAULTS AND REMEDIES. If a Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes generally may by written notice to the Issuer and the Trustee declare all the Notes to be due and payable immediately. Notwithstanding the foregoing, in the case of a Default arising from certain events of bankruptcy or insolvency as set forth in the Indenture, with respect to the Issuer or any Significant Subsidiary, all outstanding Notes will become due and payable without further action or notice. Holders of the Notes may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing Default (except a Default relating to the payment of principal or interest in- A-6 <Page> cluding an accelerated payment or the failure to make a payment on the Change of Control Payment Date or the Net Proceeds Payment Date pursuant to a Net Proceeds Offer) or a Default in complying with the provisions of Article Five of the Indenture if it determines that withholding notice is in their interest. The Holders of a majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default and its consequences under the Indenture except a continuing Default in the payment of interest on, or the principal of, or the premium, if any, on, the Notes.
