Any provision of this Subordinated Note to the contrary notwithstanding, the Company shall not make and the Subordinated Payee shall not accept, any distribution or payment of any kind whatsoever with respect to the Subordinated Obligations at any time when any of the Senior Indebtedness remains outstanding. In no event shall the Subordinated Payee commence any action or proceeding to contest or otherwise contest the enforceability of the provisions of this Subordinated Note, the validity, perfection or priority of any security interests or other liens granted to secure the Senior Indebtedness by the Company or any other Person, the rights of the Senior Agent or any holders of Senior Indebtedness or the enforceability of the Senior Credit Agreement.

To the extent that the obligation to repay the Senior Indebtedness is declared to be fraudulent, invalid or otherwise set aside under any bankruptcy, insolvency, receivership, fraudulent conveyance or similar law, then the obligation so declared fraudulent, invalid or otherwise set aside (and all other amounts that would come due with respect thereto had such obligation not been so affected) shall be deemed to be reinstated and outstanding as Senior Indebtedness for all purposes hereof as if such declaration, invalidity or setting aside had not occurred. (b) Distributions and Liquidation, Dissolution, Bankruptcy.

(c) No Payments with Respect to Subordinated Obligations. Unless ---------------------------------------------------- Section 10(b) shall be applicable, no payment or distribution of any kind or character (including, without limitation, cash, property and any payment or distribution which may be payable or deliverable by reason of the payment of any other indebtedness of the Company being subordinated to the payment of this Subordinated Note) may be made by or on behalf of the Company or accepted by the Subordinated Payee, including, without limitation, by way of set-off or otherwise, for or on account of this Subordinated Note or of any Subordinated Obligations under this Subordinated Note, or for or on account of the purchase, redemption or other acquisition of this Subordinated Note, and the Subordinated Payee shall not take or receive from the Company, directly or indirectly in any manner, payment in respect of all or any portion of this Subordinated Note or of any Subordinated Obligations under this Subordinated Note, or for or on account of the purchase, redemption or other acquisition of this Subordinated Note until the indefeasible payment and satisfaction in full in cash of all Senior Indebtedness.

In the event that ----------------------------------- notwithstanding these provisions, the Subordinated Payee receives any payment or distribution of assets of the Company of any kind, whether in cash, property or securities, including, without limitation, by way of set-off or otherwise, in respect of this Subordinated Note or any Subordinated Obligations under this Subordinated Note, that the Subordinated Payee is not entitled to receive or retain under the provisions of this Subordinated Note, then such payment or distribution shall be held by the Subordinated Payee in trust for the benefit of the Senior Agent and the Subordinated Payees of Senior Indebtedness, (segregated from other assets held by the Subordinated Payee) and shall be immediately paid over or delivered to the Senior Agent in the form received (with any necessary endorsement) to the extent necessary to make indefeasible payment and satisfaction in full in cash of all Senior Indebtedness remaining unpaid, after giving effect to any concurrent payment or distribution to or for the holders of Senior Indebtedness. In the event of the failure of the Subordinated Payee to endorse or assign any such payment or distribution, the Senior Agent is hereby irrevocably authorized to endorse or assign the same. (e) Exercise of Remedies. Until the indefeasible payment and -------------------- satisfaction in full in cash of all Senior Indebtedness, the Subordinated Payee (solely in its capacity as a holder of this Subordinated Note) shall not exercise any rights or remedies with respect to this Subordinated Note, including, without limitation, any administrative, legal, equitable or other 8 action (i) to demand or sue for collection of amounts payable hereunder, (ii) to accelerate the principal of this Subordinated Note, (iii) to commence or join with any other creditor in commencing any proceeding in connection with or premised on the occurrence of a Bankruptcy Proceeding, or (iv) to take, obtain or hold (or to permit anyone acting on its behalf to take, obtain or hold) any assets of the Company.

The Subordinated Payee acknowledges and agrees that any breach of the provisions of this Section 10 will cause irreparable harm of which the payment of monetary damages may be inadequate. For this reason, the Subordinated Payee agrees that, in addition to any remedies at law or in equity to which the Senior Agent or a Subordinated Payee of the Senior Indebtedness may be entitled, the Senior Agent or a holder of the Senior Indebtedness will be entitled to an injunction or other equitable relief to prevent breaches of the provisions of this Section 10 and to compel specific performance of such provisions. The provisions of this Section 10 are and are intended solely for the purpose of defining the relative rights of the Subordinated Payee on the one hand and the Senior Agent and the holders of Senior Indebtedness on the other hand. Nothing contained in this Section 10 or elsewhere in this Subordinated Note is intended to or shall impair, as among the Company its creditors other than the holders of Senior Indebtedness and the Subordinated Payee, the obligation of the Company, which is absolute and unconditional, to pay to the Subordinated Payee the principal of, premium, if any, and interest on this Subordinated Note as and when the same shall become due and payable in accordance with its terms. (g) Acceleration of Payment of Subordinated Note. If this Subordinated -------------------------------------------- Note is declared due and payable prior to the Maturity Date, no direct or indirect payment that is due solely by reason of such declaration shall be made, nor shall application be made of any distribution of assets of the Company to the payment, purchase or other acquisition or retirement of this Subordinated Note, unless, in either case, all Senior Indebtedness shall have been previously indefeasibly paid and satisfied in full in cash.

The exercise or beginning of the exercise by the Senior Agent of any one or more of such rights, powers or remedies shall not preclude the simultaneous or later exercise of all other such rights, powers or remedies, and no course of dealing or failure or delay on the part of any party hereto in exercising any such right, power, or remedy shall operate as a waiver thereof or otherwise prejudice its rights, powers or remedies. (i) Subrogation. Upon the indefeasible payment and satisfaction in ----------- full in cash of all Senior Indebtedness, the Subordinated Payee shall be subrogated to the rights of the holders of such Senior Indebtedness to receive payments and distributions of cash, property and securities applicable to the Senior Indebtedness until the principal of, premium, if any, and interest on this Subordinated Note shall be paid in full.

The Subordinated Payee agrees that it shall not be discharged, exonerated or have its obligations hereunder to any holder of Senior Indebtedness reduced by (i) holder's delay in proceeding against or enforcing any remedy against the Company, any collateral or any guarantor of any Senior Indebtedness or any other Person by the Senior Agent or any holder of Senior Indebtedness; (ii) the Senior Agent or any holder of Senior Indebtedness releasing the Company, any collateral or any guarantor of any Senior Indebtedness or any other Person from all or any part of such Senior Indebtedness; or (iii) the discharge of the Company, any collateral or any guarantor of any Senior Indebtedness or any other Person by operation of law or otherwise, with or without the intervention or omission of the Senior Agent or any holder of Senior Indebtedness. Any vote by the Senior Agent or any holder of Senior Indebtedness to accept or reject any plan of reorganization relating to the Company, any collateral or any guarantor of such Senior Indebtedness or any other Person, or any receipt by the Senior Agent or any holder of Senior Indebtedness receipt on account of all or part of any Senior Indebtedness of any cash, property or securities distributed in any Bankruptcy Proceeding, shall not discharge, exonerate or reduce the obligations of the Subordinated Payee hereunder to the Senior Agent and the holders of Senior Indebtedness. No right of the Senior Agent or any present or future holder of any Senior Indebtedness to enforce the provisions herein shall at any time in any way be prejudiced or impaired or affected by (i) any act or failure to act on the part of the Company or by any act or failure to act by the Senior Agent or any such holder, (ii) any non-compliance by the Company with the terms, provisions and covenants of this Subordinated Note or the Senior Credit Agreement, or (iii) any merger or consolidation of the Company or any of its subsidiaries into or with any other Person, or any sale, lease or transfer of any or all of the assets of the Company or any of its subsidiaries to any other Person, regardless in any case of any knowledge thereof of the Senior Agent or any such holder may have or be otherwise charged with. Without limiting the generality of the foregoing, the Senior Agent and the holders of Senior Indebtedness may, at any time and from time to time, without the consent of or notice to or knowledge of the Subordinated Payee, without incurring responsibility to the Subordinated Payee and without impairing or releasing the provisions herein or the obligations hereunder of the Subordinated Payee to the Senior Agent and the holders of Senior Indebtedness , 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, alter, compromise or waive any Senior Indebtedness or otherwise amend, modify or supplement in any manner any Senior Indebtedness or any instrument evidencing the same or any agreement under which any Senior Indebtedness is outstanding; (ii) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing any Senior Indebtedness; (iii) release any Person liable in any manner for the collection or payment of any 11 Senior Indebtedness; (iv) exercise or refrain from exercising any rights against the Company or any other Person; and (v) fail to perfect a security interest in any collateral for the payment of the Senior Indebtedness. The Subordinated Payee waives all rights and defenses arising out of an election of remedies by the Senior Agent or any holder of Senior Indebtedness, even though that election of remedies, including, without limitation, any nonjudicial foreclosure with respect to collateral for such Senior Indebtedness, has impaired the value of the Subordinated Payee's rights of subrogation, reimbursement or contribution against the Company, any guarantor of any Senior Indebtedness or any other Person. The Subordinated Payee expressly waives any rights or defenses it may have by reason of protection afforded to the Company or any guarantor of any Senior Indebtedness or any other Person with respect to such Senior Indebtedness pursuant to any anti-deficiency laws or other laws of similar import which limit or discharge the principal debtor's indebtedness upon judicial or nonjudicial foreclosure of real property or personal property collateral for any Senior Indebtedness. The Subordinated Payee agrees that, without the necessity of any reservation of rights against it, and without notice to or further assent by it, any demand for payment of any Senior Indebtedness made by the Senior Agent or any holder of Senior Indebtedness may be rescinded in whole or in part by the Senior Agent or any such holder, and any Senior Indebtedness may be continued, and such Senior Indebtedness, or the liability of the Company or any of its subsidiaries or any other guarantor or any other Person upon or for any part thereof, or any collateral or guarantee therefor or right of offset with respect thereto, may, from time to time, in whole or in part, be renewed, extended, modified, accelerated, compromised, waived, surrendered or released by the Senior Agent or any holder of such Senior Indebtedness, in each case without notice to or further assent by the Subordinated Payee and without impairing, abridging, releasing or affecting the subordination provided for herein. The Subordinated Payee waives any and all notice of the creation, renewal, extension or accrual of any Senior Indebtedness and notice of or proof of reliance by the Senior Agent or any holder of Senior Indebtedness upon the provisions of this Section 10. The Subordinated Payee waives presentment, protest and demand for payment. To the maximum extent permitted by law, the Subordinated Payee waives any claim it might have against the Senior Agent or any holder of Senior Indebtedness with respect to, or arising out of, any action or failure to act or any requirement of diligence on the part of the Senior Agent or any such holder of Senior Indebtedness or any requirement on the part of the Senior Agent or any such holder of Senior Indebtedness to mitigate damages resulting from any default under such Senior Indebtedness, any error of judgment, negligence or mistake or oversight whatsoever on the part of the Senior Agent or any such holder of Senior Indebtedness or its respective directors, officers, employees or agents with respect to any exercise of rights or remedies under the agreements governing or relating to such Senior Indebtedness. The Subordinated Payee, for itself and on behalf of its successors and assigns, hereby waives any and all now existing or hereafter arising rights it may have to require the Senior Agent or any holder of Senior Indebtedness to marshal assets for the benefit of the Subordinated Payee, or to otherwise direct or receive notice of the timing, order or manner of 12 any sale, collection or other enforcement of any collateral. Neither the Senior Agent nor any holder of Senior Indebtedness is under any duty or obligation, and the Subordinated Payee hereby waives any right it may have to compel the Senior Agent or any holder of Senior Indebtedness, to pursue any guarantor or other Person who may be liable for such Senior Indebtedness, or to enforce any lien or security interest in any collateral. The Subordinated Payee hereby waives and releases all rights which a guarantor or surety with respect to any Senior Indebtedness could exercise. The Subordinated Payee hereby waives any duty on the part of the Senior Agent or any holder of Senior Indebtedness to disclose to it any fact known or hereafter known by it relating to the operation or financial condition of the Company or any guarantor of such Senior Indebtedness or their respective businesses or assets. The Subordinated Payee unconditionally waives (i) notice of any of the matters referred to in this Section 10, (ii) to the extent permitted by law, all notices which may be required, whether by statute, rule of law or otherwise, to preserve intact any rights of the Senior Agent or any holder of any Senior Indebtedness against the Company, including, without limitation, any demand, presentment, protest and default, proof of notice of nonpayment under any Senior Indebtedness and notice of any failure on the part of the Company or any other Credit Party to perform and comply with any covenant, agreement, term or condition of the Senior Indebtedness, (iii) any right to the enforcement, assertion or exercise by the Senior Agent or any holder of any Senior Indebtedness of any right, power, privilege or remedy conferred in such Senior Indebtedness or otherwise, and (iv) any notice of any sale, transfer or other disposition of any Senior Indebtedness by any holder thereof. (k) Subordination to the Sub Debt Indebtedness. The Company covenants ------------------------------------------ and agrees, and the Subordination Payee by accepting this Subordinated Note covenants and agrees, that so long as any Sub Debt Default or Sub Debt Event of Default shall have occurred and be continuing, no payment of principal of (and premium, if any) or interest on, or any other payment obligations with respect to, this Subordinated Note or any judgment with respect hereto shall be made by or on behalf of the Company or any other Credit Party.

Any Transfer -------------------- or attempted Transfer of this Subordinated Note in violation of any provision of this Subordinated Note shall be null and void, and the Company shall not record such Transfer on its books or treat any purported transferee of this Subordinated Note as the owner of this Subordinated Note for any purpose. 12. Counterparts. This Subordinated Note may be executed in separate ------------ counterparts each of which shall be an original and all of which taken together shall constitute one and the same agreement. 13. Usury Laws. It is the intention of the Company and the ---------- Subordinated Payee to conform strictly to all applicable usury laws now or hereafter in force, and any interest payable under this Subordinated Note shall be subject to reduction to the amount not in excess of the maximum legal amount allowed under the applicable usury laws as now or hereafter construed by the courts having jurisdiction over such matters. If the maturity of this Subordinated Note is accelerated by reason of an election by the holder hereof resulting from an Event of Default, voluntary prepayment by the Company or otherwise, then earned interest may never include more than the maximum amount permitted by law, computed from the date hereof until payment, and any interest in excess of the maximum amount permitted by law shall be canceled automatically and, if theretofore paid, shall at the option of the Subordinated Payee either be rebated to the Company or credited on the principal amount of this Subordinated Note, or if this Subordinated Note has been paid, then the excess shall be rebated to the Company. The aggregate of all interest (whether designated as interest, service charges, points or otherwise) contracted for, chargeable, or receivable under this Subordinated Note shall under no circumstances exceed the maximum legal rate upon the unpaid principal balance of this Subordinated Note remaining unpaid from time to time. If such interest does exceed the maximum legal rate, it shall be deemed a mistake and such excess shall be canceled automatically and, if theretofore paid, rebated to the Company or credited on the principal amount of this Subordinated Note, or if this Subordinated Note has been repaid, then such excess shall be rebated to the Company. 14. No Strict Construction. The parties hereto have participated ---------------------- jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties hereto, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any of the provisions of this Agreement. 15. Amendments; Waivers. So long as any Senior Indebtedness remains ------------------- outstanding, no amendment or modification to or waiver of any provisions of, or the definitions of any terms appearing in, Section 10, or to or of any other provision of this Subordinated Note may be made that affects the rights of any holder of Senior Indebtedness then outstanding unless the holders of such Senior Indebtedness, or any representative of such holders authorized to give a consent, consent to such amendment, modification or waiver. 14 16. Conversion. ---------- (a) Conversion Procedure. -------------------- (i) Voluntary Conversion; Automatic Conversion. At any time after the ------------------------------------------ date hereof and prior to the payment of this Subordinated Note in full, the then Subordinated Payee may convert this Subordinated Note into a number of Class A Units determined by dividing (x) the then Convertible Amount (as herein defined) by (y) $1,600 (the "Conversion Price"). Notwithstanding ---------------- anything contained herein to the contrary, if as of September 15, 2003 this Subordinated Note has not been paid in full, then this Subordinated Note shall automatically be converted into a number of Class A Units in accordance with the formula contained in the first sentence of this Section 16(a)(i). In addition, this Subordinated Note is subject to mandatory conversion pursuant to the terms of Section 13 of the Securityholders Agreement. If the Subordinated Payee is not a Member (as such term is defined in the LLC Agreement) at the time of a conversion of this Subordinated Note, then, at the time of such conversion of this Subordinated Note, such Subordinated Payee agrees to deliver to the Secretary of Holdings an executed joinder to the LLC Agreement and any other documentation necessary in accordance with the requirements of the LLC Agreement or any of the Related Agreements (as such term is defined in the LLC Agreement). For purposes of this Subordinated Note, the "Convertible Amount" at any time shall equal (x) the then outstanding ------------------ principal amount of this Subordinated Note plus (y) the interest which has ---- then accrued in accordance with the provisions contained herein and which is then unpaid, in each case, at such time. (ii) Effect of Conversion. A conversion of this Subordinated Note will -------------------- be deemed to have been effected as of the close of business on the date on which this Subordinated Note has been surrendered for conversion by the then Subordinated Payee to the Secretary of Holdings; provided, that in the event of an automatic conversion of this Subordinated Note, such automatic conversion will be deemed to have been effected as of the close of business on the date of such automatic conversion. At such time as such conversion has been effected, the rights of the then Subordinated Payee (as well as any and all prior Subordinated Payees and any other former or current holder of this Subordinated Note) under this Subordinated Note will cease, the Company shall thereafter have no obligation to make any principal, interest or other payments under this Subordinated Note and such Subordinated Payee shall be deemed to be the record holder of the applicable Class A Units which this Subordinated Note shall have then been converted into. If this Subordinated Note is converted pursuant to this Section 16, no principal amount of, accrued interest on or any other amount pursuant to this Subordinated Note will be payable at any time as of or after such conversion. (b) Subdivision or Combination of Class A Units. If Holdings at any ------------------------------------------- time subdivides (by any unit split, unit distribution or otherwise) the Class A Units into a greater number of units, then the Conversion Price in effect immediately prior to such subdivision will be proportionately reduced. If Holdings at any time combines (by reverse unit split or otherwise) the Class A Units into a smaller number of units, then the Conversion Price in effect immediately prior to such combination will be proportionately increased. 15 (c) Organic Change. -------------- (i) Organic Change Defined. Any recapitalization, reorganization, ---------------------- reclassification, consolidation or merger of Holdings, which in each case is effected in such a manner that holders of the Class A Units are entitled to receive stock or any other securities or property with respect to or in exchange for such Class A Units is referred to herein as an "Organic ------- Change." ------ (ii) Provisions for Organic Change. Prior to the consummation of any ----------------------------- Organic Change, Holdings' Board of Directors will, in good faith, make lawful and adequate provision to insure that the Subordinated Payee will thereafter have the right to acquire and receive, in lieu of or addition to (as the case may be) the Class A Units immediately theretofore acquirable and receivable upon the conversion of this Subordinated Note, such shares of stock and/or such securities or property as may be issued or payable with respect to or in exchange for the Class A Units immediately theretofore acquirable and receivable upon conversion of this Subordinated Note had such Organic Change not taken place. (d) Pre-Emptive Rights. The Company and the Subordinated Payee ------------------ acknowledge and agree to comply with the pre-emptive rights of its equityholders, if any, in connection with any conversion of this Note pursuant to this Section 16. 17. Severability. If the provisions of this Subordinated Note, or the ------------ application of such provision to any Person or circumstance, shall be held invalid, illegal or unenforceable in any jurisdiction, the validity, legality and enforceability of the remaining provisions in this Subordinated Note, or the application of such provision in jurisdictions or to Persons or circumstances other than to those to which it is held invalid, illegal or unenforceable shall not be affected thereby. 16 IN WITNESS WHEREOF, the Company has executed and delivered this Junior Subordinated Unsecured Convertible Promissory Note on the date specified above.
