     This Note and the indebtedness evidenced hereby are subordinate in the manner and to the extent set forth in that certain Intercreditor Agreement, dated as of the date hereof, among Payee, Ableco Finance LLC, a Delaware limited liability company (“Ableco”), as collateral agent for the Lenders as defined therein (in such capacity, together with any successor collateral agent, the “Collateral Agent”), and GMAC Commercial Finance LLC (“GMAC”), as administrative agent for the Lenders defined therein (in such capacity, together with any successor administrative agent, the “Administrative Agent”; and together with the Collateral Agent, each an “Agent” and collectively, the “Agents”) (as amended, restated, supplemented, or otherwise modified from time to time, the “Subordination Agreement”), and each holder of this Note, by its acceptance hereof, shall be bound by the provisions of the Subordination Agreement.

     1. Interest.

     (a) Interest Accrual. Interest shall accrue on a quarterly basis at a rate of fifteen and one-quarter percent (15.25%) per annum (calculated on the basis of a 360-day year comprised of twelve 30-day months) on the unpaid principal balance of this Note outstanding from time to time, or (if less) at the highest rate then permitted by applicable law. The Maker shall pay to the

Payee all accrued and unpaid interest on the Interest Payment Dates, beginning March 31, 2008, by increasing the principal amount of this Note by the amount of such accrued and unpaid interest (“PIK Interest”) pursuant to Section 1(b) below. All accrued interest which for any reason has not theretofore been paid shall be paid in full on the date on which the final principal payment on this Note is made. Interest shall accrue on any principal payment due under this Note and, to the extent permitted by applicable law, on any interest which has not been paid on the date on which it is due and payable until such time as payment therefor is actually delivered to the Payee. Upon the conversion of all or part of the amounts outstanding under this Note into Common Stock pursuant to Section 8, interest will cease to accrue with respect to any such amounts converted into Common Stock.

     (b) PIK Interest; Capitalization of Interest. All interest which accrues on or before any Interest Payment Date (the “Capitalization Date”) shall be deemed to be paid in kind and added to the principal amount outstanding hereunder, in each case, as of the Capitalization Date. Except as expressly provided herein, the term “Note” shall include all PIK Interest deemed to be added to the principal amount outstanding hereunder pursuant to this Section 1(b).

     2. Principal.

     (a) Maturity Date. On June 29, 2012 (the “Maturity Date”), the Maker shall pay the entire unpaid principal amount of this Note then outstanding to the Payee, together with all accrued and unpaid interest thereon.

     (b) Mandatory Prepayment. Subject to the terms of the Subordination Agreement and the Payee’s right to convert this Note into Common Stock pursuant to Section 8, upon the occurrence of a Fundamental Change, the Maker shall redeem this Note in full at a price equal to the unpaid principal amount of the Note, plus all accrued and unpaid interest. Except as provided in the foregoing sentence, this Note may not be prepaid by the Maker without the consent of the Majority Payees.

     (c) Replacement Notes. The Maker or the Payee may, but shall not be obligated to, request the issuance of replacement notes to evidence any increases in the principal amount of this Note pursuant to Section 1(b) with such replacement notes being identical in form and substance in all respects to this Note. Upon any such request, the Maker shall issue such replacement notes and the holder(s) of this Note or such replacement notes shall return such notes to be replaced to the Maker, in each case marked “cancelled”, or deliver to the Maker a lost note indemnity in form and substance reasonably satisfactory to the Maker. The replacement and cancellation of notes pursuant to this Section 2(c) shall in no way be a novation of the indebtedness evidenced by the notes being replaced and cancelled nor shall the security interests granted pursuant to any Senior Subordinated Note Document be released, terminated or otherwise impaired by such replacement and cancellation.

     (d) Application of Principal Payments and Reductions. All payments and prepayments of principal on this Note and all principal reductions effected in accordance with the terms of this Note shall be applied first, to the accrued and unpaid interest due under this Note, and second, to the unpaid principal balance of this Note then outstanding (including principal attributable to the capitalization of PIK Interest in accordance with Section 1(b)).

In consideration of the loan made pursuant to this Note, and not in limitation of any other fee paid or payable to the Payee under any of the Senior Subordinated Note Documents at any time, the Maker shall, on the date hereof, pay to the Payee, or the Payee, at its option, may set off against the amount loaned to the Maker pursuant to this Note, a fee in the amount of $150,000, which fee shall be fully earned and payable as of the date hereof and constitutes part of the Obligations. The Maker agrees that, once paid, the foregoing fee shall be nonrefundable.

     5. Representations and Warranties. The Maker hereby represents and warrants to the Payee that each of the representations and warranties set forth in the First Lien Credit Agreement are true and correct as of the date hereof, and each such representation and warranty is incorporated mutatis mutandis as if set forth fully in this Note and as if applicable to the Payee and the Senior Subordinated Note Documents.

     6. Covenants.

     (a) Maintenance of the Maker’s Business. So long as any amount remains due and outstanding under this Note, the Maker will, and will cause each of its Subsidiaries to:

          (i) at all times cause to be done all things necessary to maintain, preserve and renew its corporate existence (except that a Subsidiary may be merged or liquidated into the

Maker or another Subsidiary) and all material licenses, authorizations and permits necessary to the conduct of its businesses;

          (ii) maintain and keep its properties in good repair, working order and condition, and from time to time make all necessary or desirable repairs, renewals and replacements, so that its businesses may be properly and advantageously conducted in all material respects at all times;

          (iii) pay and discharge when payable all taxes, assessments and governmental charges imposed upon its properties or upon the income or profits therefrom (in each case before the same becomes delinquent and before penalties accrue thereon) and all claims for labor, materials or supplies to the extent to which the failure to pay or discharge such obligations would reasonably be expected to have a material adverse effect upon the financial condition, operating results, assets, operations or business prospects of the Maker and its Subsidiaries taken as a whole, unless and to the extent that the same are being contested in good faith and by appropriate proceedings and adequate reserves (as determined in accordance with GAAP) have been established on its books and financial statements with respect thereto;

          (iv) comply with all other obligations which it incurs pursuant to any contract or agreement, whether oral or written, express or implied, as such obligations become due to the extent to which the failure to so comply would reasonably be expected to have a material adverse effect upon the financial condition, operating results, assets, operations or business prospects of the Maker and its Subsidiaries taken as a whole, unless and to the extent that the same are being contested in good faith and by appropriate proceedings and adequate reserves (as determined in accordance with GAAP) have been established on its books and financial statements with respect thereto;

          (v) comply with all applicable laws, rules and regulations of all governmental authorities, the violation of which would reasonably be expected to have a material adverse effect upon the financial condition, operating results, assets, operations or business prospects of the Maker and its Subsidiaries taken as a whole;

          (vi) apply for and continue in force with good and responsible insurance companies adequate insurance covering risks of such types and in such amounts as are customary for companies of similar size engaged in similar lines of business; and

Upon request, the Maker will deliver to the Payee a written statement as to whether it has complied with such requirements. The Maker’s failure to file a report required to be filed under the

4

Securities Act or the Exchange Act, as the case may be, shall not constitute an Event of Default (as defined in Section 7 below) hereunder if such failure, in the case of an Exchange Act filing, is excused by the application of Exchange Act Rule 12b-25.

     (c) Shareholder Approval. The Maker will submit (i) the Senior Subordinated Note Documents and the transactions contemplated hereby and thereby (including the issuance of shares to the Payee should the Payee exercise its right to convert this Note into shares of Common Stock pursuant to Section 8 hereof), and (ii) an amendment to the articles of incorporation of the Maker increasing the number of authorized shares to an amount sufficient to permit conversion of this Note pursuant to Section 8 hereof (including PIK Interest) for approval by its shareholders at the Maker’s next annual shareholders meeting. The Maker shall include in the proxy statement for such meeting the recommendation of the Special Committee of the Board of Directors and the Board of Directors of the Maker in favor of the approval of the Proposals and such proxy statement shall provide that the vote of the shares held by the Payee shall be sufficient for approval of the Proposals (provided the Payee owns at least 66 2/3% of the outstanding shares of the Maker on the record date for such meeting). The proxy statement for such annual Meeting shall be filed with the SEC not later than April 29, 2008 and such meeting held no later than May 31, 2008.

     (d) Audited Financial Statements. The Maker agrees to deliver, or cause to be delivered, to the Payee the Audited Financial Statements for each Fiscal Year substantially simultaneously with the delivery thereof to the Administrative Agent and the Lenders under the First Lien Credit Agreement.

     (e) Notifications of Defaults on First Lien Financing Agreement.

     (f) Guarantees and Collateral. The Maker will deliver, or cause to delivered, such guarantees, security agreement, mortgages and other collateral documents as are necessary to provide the Payee with guarantees by the same entities and security interests in the same assets as the guarantees and collateral documents delivered pursuant to the First Lien Credit Agreement, together with such opinions, title insurance policies, endorsements, financing statements, control agreements (other than to the extent the Collateral Agent is the bailee for the Payee in accordance with the Subordination Agreement) and other agreements, documents and instruments in furtherance of such guarantees and collateral arrangements as the Payee may from time to time reasonably request.

     (g) Additional Subsidiary Guarantors. Each Domestic Subsidiary acquired or created shall as soon as practicable, but in any event within five (5) Business Days after the time it becomes a guarantor of the obligations under the First Lien Credit Agreement, execute a guaranty in the form attached hereto as Exhibit A and reasonably satisfactory in form and substance to the Majority Payees.

          (ii) the occurrence of an Insolvency Event;

          (iii) the failure of the Maker to deliver any shares of Common Stock required to be delivered by the Maker upon conversion of this Note pursuant to Section 8, which failure is not remedied within fifteen (15) calendar days of the Payee’s conversion of this Note;

          (v) (A) the failure of the Maker or any of its Subsidiaries to pay in full any principal of or interest or premium on any of its indebtedness (excluding the obligations hereunder) to the extent that the aggregate principal amount of all such indebtedness exceeds $1,000,000 when due (whether by scheduled maturity, required prepayment, acceleration, demand or otherwise) and such failure shall continue after any applicable grace period, if any, specified in the agreement or instrument relating to such indebtedness, or (B) any other default under any agreement or instrument relating to any such indebtedness, or any other event, shall occur and shall continue after the applicable grace period, if any, specified in such agreement or instrument, if the effect of such other default or event is to accelerate the maturity of such indebtedness;

          (vii) any representation or warranty made or deemed made by or on behalf of Maker or any Guarantor or by any officer of the foregoing under or in connection with the Senior Subordinated Note Documents or under or in connection with any report, certificate, or other document delivered to any Payee shall have been incorrect in any material respect when made or deemed made;

          (viii) any material provision of this Note, or any other Senior Subordinated Note Document shall at any time for any reason (other than pursuant to the express terms thereof) cease to be valid and binding on or enforceable against the Maker or any Guarantor

6

intended to be a party thereto, or the validity or enforceability thereof shall be contested by any party thereto, or a proceeding shall be commenced by the Maker or any Guarantor or any governmental authority having jurisdiction over any of them, seeking to establish the invalidity or unenforceability thereof, or the Maker or any Guarantor shall deny in writing that it has any liability or obligation purported to be created under this Note, or any other Senior Subordinated Note Document; or

          (ix) any security agreement, any mortgage or any other security document, after delivery thereof pursuant hereto, shall for any reason fail or cease to create a valid and perfected lien in favor of the Payee on any Collateral purported to be covered thereby.

     (b) Remedies.

          (i) Subject to the Subordination Agreement, upon the occurrence of an Event of Default, the Majority Payees may declare all or any portion of the unpaid Obligations to be immediately due and payable (provided, however, that if an Event of Default specified in Section 7(a)(ii) occurs, the entire unpaid Obligations shall forthwith become and be immediately due and payable without any declaration or other act on the part of the Majority Payees).

          (ii) Subject to the Subordination Agreement, upon the occurrence of any Event of Default and for so long as any Event of Default is continuing, the interest rate on this Note shall increase immediately by an increment of two (2) percentage points to the extent permitted by law.

All additional interest accrued pursuant to this Section 7(b)(ii) shall be capitalized on any relevant Capitalization Date in accordance with Section 1(b).

          (iii) Each Payee shall also have any other rights which such Payee may have been afforded under any contract or agreement at any time and any other rights which such Payee may have pursuant to applicable law.

     8. Conversion.

     (a) Conversion Procedure.

          (i) At any time and from time to time prior to the payment of this Note in full, at the Payee’s option, the Payee may convert all or any portion of the principal amount and accrued and unpaid interest outstanding under this Note into a number of shares of the Conversion Stock (excluding any fractional share) determined by dividing the principal amount designated by such Payee to be converted by the Conversion Price then in effect; provided, that such conversion may not take place until the Maker’s shareholders (without giving effect to the conversion contemplated by this Section 8(a)(i)) have approved the issuance of the Common Stock issuable upon conversion of this Note.

          (ii) Except as otherwise expressly provided herein, each conversion of this Note shall be deemed to have been effected as of the close of business on the date on which this Note has been surrendered for conversion at the principal office of the Maker. At such time as

7

such conversion has been effected, the rights of the Payee as the holder of this Note to the extent of the conversion shall cease, and the Person or Persons in whose name or names any certificate or certificates for shares of Conversion Stock are to be issued upon such conversion shall be deemed to have become the holder or holders of record of the shares of Conversion Stock represented thereby.

          (iii) Notwithstanding any other provision hereof, if a conversion of any portion of this Note is to be made in connection with a sale of the Maker, the conversion of any portion of this Note may, at the election of the Payee, be conditioned upon the consummation of the sale of the Maker, in which case such conversion shall not be deemed to be effective until the consummation of such transaction.

          (iv) As soon as possible after a conversion has been effected (but in any event within five (5) Business Days in the case of clause (A) below), the Maker shall deliver to the converting Payee:

               (A) a certificate or certificates representing the number of shares of Conversion Stock (excluding any fractional share) issuable by reason of such conversion in such name or names and such denomination or denominations as the converting Payee has specified; and

               (B) a new Note representing any portion of the principal amount or accrued and unpaid interest which was represented by the Note surrendered to the Maker in connection with such conversion but which was not converted.

          (v) If any fractional share of Conversion Stock would, except for the provisions hereof, be deliverable upon conversion of this Note, the Maker, in lieu of delivering such fractional share, shall pay an amount equal to the Market Price of such fractional share as of the date of such conversion.

          (vi) The issuance of certificates for shares of Conversion Stock upon conversion of this Note shall be made without charge to the Payee hereof for any issuance tax in respect thereof or other cost incurred by the Maker in connection with such conversion and the related issuance of shares of Conversion Stock. Upon conversion of this Note, the Maker shall take all such actions as are necessary in order to insure that the Conversion Stock issuable with respect to such conversion shall be validly issued, fully paid and nonassessable.

          (vii) The Maker shall not close its books against the transfer of Conversion Stock issued or issuable upon conversion of this Note in any manner which interferes with the timely conversion of this Note. The Maker shall assist and cooperate with any Payee required to make any governmental filings or obtain any governmental approval prior to or in connection with the conversion of this Note (including, without limitation, making any filings required to be made by the Maker).

          (viii) The Maker shall at all times reserve and keep available out of its authorized but unissued shares of Conversion Stock, solely for the purpose of issuance upon the conversion of the Note, such number of shares of Conversion Stock issuable upon the conversion of all outstanding Notes. All shares of Conversion Stock which are so issuable shall, when

8

issued, be duly and validly issued, fully paid and nonassessable and free from all taxes, liens and charges. The Maker shall take all such actions as may be necessary to assure that all such shares of Conversion Stock may be so issued without violation of any applicable law or governmental regulation or any requirements of any domestic securities exchange upon which shares of Conversion Stock may be listed (except for official notice of issuance which shall be immediately delivered by the Maker upon each such issuance).

     (b) Conversion Price.

          (i) The initial Conversion Price shall be $5.00 per share of Common Stock. In order to prevent dilution of the conversion rights granted under the Notes, the Conversion Price shall be subject to adjustment from time to time pursuant to this Section 8(b).

          (ii) If and whenever the Maker issues or sells, or in accordance with Section 8(c) is deemed to have issued or sold, any shares of Common Securities for a consideration per share less than the Conversion Price in effect immediately prior to such time, then immediately upon such issue or sale the Conversion Price shall be reduced to the Conversion Price determined by dividing (A) an amount equal to the sum of (x) the product derived by multiplying the Conversion Price in effect immediately prior to such issue or sale by the number of shares of Common Stock Deemed Outstanding immediately prior to such issue or sale, plus (y) the consideration, if any, received by the Maker upon such issue on sale, by (B) the number of shares of Common Stock Deemed Outstanding immediately after such issue or sale.

     (c) Effect on Conversion Price of Certain Events. For purposes of determining the adjusted Conversion Price under Section 8(b), the following shall be applicable:

          (i) Issuance of Rights or Options. If the Maker in any manner grants or sells any Options and the price per share for which Common Securities are issuable upon the exercise of such Options, or upon conversion or exchange of any Convertible Securities issuable upon exercise of such Options, is less than the Conversion Price in effect immediately prior to the time of the granting or sale of such Options, then the total maximum number of shares of Common Securities issuable upon the exercise of such Options, or upon conversion or exchange of the total maximum amount of such Convertible Securities issuable upon the exercise of such Options, shall be deemed to be outstanding and to have been issued and sold by the Maker at the time of the granting or sale of such Option for such price per share. For purposes of this Section 8(c)(i), the “price per share for which Common Securities are issuable upon exercise of such Options or upon conversion or exchange of such Convertible Securities” is determined by dividing (A) the total amount, if any, received or receivable by the Maker as consideration for the granting or sale of such Options, plus the minimum aggregate amount of additional consideration payable to the Maker upon the exercise of all such Options, plus in the case of such Options which relate to Convertible Securities, the minimum aggregate amount of additional consideration, if any, payable to the Maker upon the issuance or sale of such Convertible Securities and the conversion or exchange thereof, by (B) the total maximum number of shares of Common Securities issuable upon the exercise of such Options or upon the conversion or exchange of all such Convertible Securities issuable upon the exercise of such Options. No adjustment of the Conversion Price shall be made upon the actual issuance of such Common Securities or of such Convertible Securities upon the exercise of such Options or upon the actual

9

issuance of such Common Securities upon conversion or exchange of such Convertible Securities.

          (ii) Issuance of Convertible Securities. If the Maker in any manner issues or sells any Convertible Securities and the price per share for which Common Securities are issuable upon conversion or exchange thereof is less than the Conversion Price in effect immediately prior to the time of such issue or sale, then the maximum number of shares of Common Securities issuable upon conversion or exchange of all such Convertible Securities shall be deemed to be outstanding and to have been issued and sold by the Maker at the time of the issuance or sale of such Convertible Securities for such price per share. For the purposes of this Section 8(c)(ii), the “price per share for which Common Securities are issuable upon conversion or exchange thereof” is determined by dividing (A) the total amount received or receivable by the Maker as consideration for the issue or sale of such Convertible Securities, plus the minimum aggregate amount of additional consideration, if any, payable to the Maker upon the conversion or exchange thereof, by (B) the total maximum number of shares of Common Securities issuable upon the conversion or exchange of all such Convertible Securities. No adjustment of the Conversion Price shall be made upon the actual issue of such Common Securities upon conversion or exchange of such Convertible Securities, and if any such issue or sale of such Convertible Securities is made upon exercise of any Options for which adjustments of the Conversion Price had been or are to be made pursuant to other provisions of this Section 8(c), no further adjustment of the Conversion Price shall be made by reason of such issue or sale.

          (iii) Change in Option Price or Conversion Rate. If the purchase price provided for in any Option, the additional consideration (if any) payable upon the issue, conversion or exchange of any Convertible Security, or the rate at which any Convertible Security is convertible into or exchangeable for Common Securities changes at any time, the Conversion Price in effect at the time of such change shall be adjusted immediately to the Conversion Price which would have been in effect at such time had such Option or Convertible Security originally provided for such changed purchase price, additional consideration or changed conversion rate, as the case may be, at the time initially granted, issued or sold; provided, that if such adjustment of the Conversion Price would result in an increase in the Conversion Price then in effect, such adjustment shall not be effective until thirty (30) calendar days after written notice thereof has been given to all Payees. For purposes of this Section 8(c), if the terms of any Option or Convertible Security which was outstanding as of the date of issuance of this Note are changed in the manner described in the immediately preceding sentence, then such Option or Convertible Security and the Common Securities deemed issuable upon exercise, conversion or exchange thereof shall be deemed to have been issued as of the date of such change; provided, that no such change shall at any time cause the Conversion Price hereunder to be increased.

          (iv) Treatment of Expired Options and Unexercised Convertible Securities. Upon the expiration of any Option or the termination of any right to convert or exchange any Convertible Securities without the exercise of such Option or right, the Conversion Price then in effect hereunder shall be adjusted immediately to the Conversion Price which would have been in effect at the time of such expiration or termination had such Option or Convertible Securities, to the extent outstanding immediately prior to such expiration or termination, never been issued; provided, that if such expiration or termination would result in an increase in the Conversion

10

Price then in effect, such increase shall not be effective until thirty (30) calendar days after written notice thereof has been given to all Payees. For purposes of this Section 8(c), the expiration or termination of any Option or Convertible Security which was outstanding as of the date of issuance of this Note shall not cause the Conversion Price hereunder to be adjusted unless, and only to the extent that, a change in the terms of such Option or Convertible Security caused it to be deemed to have been issued after the date of issuance of this Note.

          (v) Calculation of Consideration Received. If any Common Securities, Options or Convertible Securities are issued or sold or deemed to have been issued or sold for cash, the consideration received therefor shall be deemed to be the net amount received by the Maker therefor. In case any Common Securities, Options or Convertible Securities are issued or sold for a consideration other than cash, the amount of the consideration other than cash received by the Maker shall be the fair value of such consideration, except where such consideration consists of securities, in which case the amount of consideration received by the Maker shall be the Market Price thereof as of the date of receipt. In case any Securities, Options or Convertible Securities are issued to the owners of the non-surviving entity in connection with any merger in which the Maker is the surviving entity, the amount of consideration therefor shall be deemed to be the fair value of the portion of the net assets of the non-surviving entity that is attributable to such Common Securities, Options or Convertible Securities, as the case may be. The fair value of any consideration or net assets other than cash and securities (and, if applicable, the portion thereof attributable to any such stock or securities) shall be determined jointly by the Maker and the holders of a majority of the outstanding principal amount of the Notes. If such parties are unable to reach agreement within a reasonable period of time, such fair value shall be determined by an appraiser jointly selected by the Maker and the holders of a majority of the outstanding principal amount of the Notes. The determination of such appraiser shall be final and binding upon the parties, and the fees and expenses of such appraiser shall be borne by the Maker.

          (vi) Integrated Transactions. In case any Option is issued in connection with the issue or sale of other securities of the Maker, together comprising one integrated transaction in which no specific consideration is allocated to such Options by the parties thereto, the Options shall be deemed to have been issued without consideration.

          (vii) Treasury Shares. The number of shares of Common Securities outstanding at any given time does not include shares owned or held by or for the account of the Maker or any Subsidiary, and the disposition of any shares so owned or held shall be considered an issue or sale of Common Securities.

          (viii) Record Date. If the Maker takes a record of the holders of Common Securities for the purpose of entitling them (A) to receive a dividend or other distribution payable in Common Securities, Options or in Convertible Securities or (B) to subscribe for or purchase Common Securities, Options or Convertible Securities, then such record date shall be deemed to be the date of the issue or sale of the shares of Common Securities deemed to have been issued or sold upon the declaration of such dividend or the making of such other distribution or the date of the granting of such right of subscription or purchase, as the case may be.

11

     (d) Subdivision or Combination of Common Securities. If the Maker at any time subdivides (by any stock split, stock dividend or otherwise) one or more classes of its outstanding shares of Common Securities into a greater number of shares, the Conversion Price in effect immediately prior to such subdivision shall be proportionately reduced, and if the Maker at any time combines (by reverse stock split or otherwise) one or more classes of its outstanding shares of Common Securities into a smaller number of shares, the Conversion Price in effect immediately prior to such combination shall be proportionately increased.

     (e) Reorganization, Reclassification, Consolidation, Merger or Sale. Any recapitalization, reorganization, reclassification, consolidation, merger, sale of all or substantially all of the Maker’s assets or other transaction, which in each case is effected in such a manner that holders of Common Securities are entitled to receive (either directly or upon subsequent liquidation) stock, securities or assets with respect to or in exchange for Common Securities is referred to herein as an “Organic Change.” Prior to the consummation of any Organic Change, the Maker shall make lawful and adequate provision (in form and substance satisfactory to the holders of a majority of the principal amount of the Notes then outstanding) to ensure that each of the Payees shall thereafter have the right to acquire and receive, in lieu of or addition to (as the case may be) shares of Conversion Stock immediately theretofore acquirable and receivable upon the conversion of such holder’s Note, such shares of stock, securities or assets as would have been issued or payable in such Organic Change (if the Payee had exercised this Note immediately prior to such Organic Change) with respect to or in exchange for the number of shares of Conversion Stock immediately theretofore acquirable and receivable upon conversion of such Payee’s Note had such Organic Change not taken place. In any such case, appropriate provision (in form and substance satisfactory to the Majority Payees) shall be made with respect to such Payee’s rights and interests to insure that the provisions of this Section 8 and Sections 9 and 10 shall thereafter be applicable in relation to any shares of stock, securities or assets thereafter deliverable upon the conversion of the Notes (including, in the case of any such consolidation, merger or sale in which the successor entity or purchasing entity is other than the Maker, an immediate adjustment of the Conversion Price to the value for the Common Securities reflected by the terms of such consolidation, merger or sale, and a corresponding immediate adjustment in the number of shares of Conversion Stock acquirable and receivable upon conversion of the Notes, if the value so reflected is less than the Conversion Price in effect immediately prior to such consolidation, merger or sale). The Maker shall not effect any such consolidation, merger or sale, unless prior to the consummation thereof, the successor entity (if other than the Maker) resulting from consolidation or merger or the entity purchasing such assets assumes by written instrument (in form reasonably satisfactory to the Majority Payees), the obligation to deliver to each such holder such shares of stock, securities or assets as, in accordance with the foregoing provisions, such holder may be entitled to acquire.

     (f) Certain Events. If any event occurs of the type contemplated by the provisions of this Section 8 but not expressly provided for by such provisions (including, without limitation, the granting of stock appreciation rights, phantom stock rights or other rights with equity features), then the Maker’s board of directors shall make an appropriate adjustment in the Conversion Price so as to protect the rights of the Payees; provided, that no such adjustment shall increase the Conversion Price as otherwise determined pursuant to this Section 8 or decrease the number of shares of Conversion Stock issuable upon conversion of the Notes then outstanding.

12

     10. Purchase Rights. If at any time the Maker grants, issues or sells any Options, Convertible Securities or rights to purchase stock, warrants, securities or other property pro rata to the record holders of any class of Common Securities (the “Purchase Rights”), then each Payee shall be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which such Payee could have acquired if such Payee had held the number of shares of Conversion Stock acquirable upon conversion of such Payee’s Note immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of Common Securities are to be determined for the grant, issue or sale of such Purchase Rights.

     11. Registration Agreement. The Maker and the Payee agree and acknowledge that the shares issuable by the Maker pursuant to Section 8 of this Note are “Sun Registrable Securities” pursuant to and as defined in that certain Registration Agreement dated February 21, 2003 by and among the Maker, the Payee and the other parties signatory thereto; provided, that if this Note is assigned pursuant to Section 15 of this Note to any Person other than an affiliate of Sun Mackie, LLC, such assignee will be deemed a party to such Registration Agreement and the shares issuable by the Maker pursuant to Section 8 of this Note shall be “Other Registrable Securities” pursuant to and as defined in such Registration Agreement.

Business Day, and interest shall continue to accrue at the required rate hereunder until any such payment is made.

The rights and remedies of the Payee expressly set forth in this Note are cumulative and in addition to, and not exclusive of, all other rights and remedies available at law, in equity or otherwise. No failure or delay on the part of the Payee in exercising any right, power or privilege shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, power or privilege preclude any other or further exercise thereof or the exercise of any other right, power or privilege or be construed to be a waiver of any Event of Default. No course of dealing between the Maker and the Payee or their agents or employees shall be effective to amend, modify or discharge any provision of this Note or to constitute a waiver of any Event of Default. No notice to or demand upon Maker in any case shall entitle Maker to any other or further notice or demand in similar or other circumstances or constitute a waiver of the right of the Payee to exercise any right or remedy or take any other or further action in any circumstances without notice or demand.

     25. Construction. The definitions of terms herein shall apply equally to the singular and plural forms of the terms defined. Whenever the context may require, any pronoun shall include the corresponding masculine, feminine and neuter forms.

If the maturity of this Note is accelerated by reason of an election by the Payee resulting from an Event of Default, voluntary prepayment by the Maker 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 Payee either be rebated to the Maker or credited on the principal amount of this Note, or if this Note has been paid, then the excess shall be rebated to the Maker.

Without limiting the generality of the foregoing, each Guarantor’s liability shall extend to all amounts that constitute part of the Guaranteed Obligations and would be owed by the Maker to the holders under any Senior Subordinated Note Document but for the fact that they are unenforceable or not allowable due to the existence of a bankruptcy, reorganization or similar proceeding involving any Maker or Guarantor.

     2. Guaranty Absolute. Each Guarantor jointly and severally guarantees that the Guaranteed Obligations will be paid strictly in accordance with the terms of the Senior Subordinated Note Documents, regardless of any law, regulation or order now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of the holders with respect thereto. Each Guarantor agrees that this Exhibit constitutes a guaranty of payment when due and not of collection and waives any right to require that any resort be made by any holder to any Collateral. The obligations of each Guarantor under this Exhibit are independent of the Guaranteed Obligations, and a separate action or actions may be brought and prosecuted against each Guarantor to enforce such obligations, irrespective of whether any action is brought against the Maker or any Guarantor or whether the Maker or any Guarantor is joined in any such action or actions. The liability of each Guarantor under this Exhibit shall be irrevocable, absolute and unconditional irrespective of, and each Guarantor hereby irrevocably waives any defenses it may now or hereafter have in any way relating to, any or all of the following:

(a) any lack of validity or enforceability of any Senior Subordinated Note Document or any agreement or instrument relating thereto;

(b) any change in the time, manner or place of payment of, or in any other term of, all or any of the Guaranteed Obligations, or any other amendment or waiver of or any consent to departure from any Senior Subordinated Note Document, including any increase in the Guaranteed Obligations resulting from the extension of additional credit to the Maker or any Guarantor or otherwise;

(c) any taking, exchange, release or non-perfection of any Collateral, or any taking, release or amendment or waiver of or consent to departure from any other guaranty, for all or any of the Guaranteed Obligations;

(d) the existence of any claim, set-off, defense or other right that any Guarantor may have at any time against any Person, including, without limitation, any holder;

(e) any change, restructuring or termination of the corporate, limited liability company or partnership structure or existence of the Maker or any Guarantor; or

(f) any other circumstance (including any statute of limitations) or any existence of or reliance on any representation by any holder that might otherwise constitute a defense available to, or a discharge of, the Maker, any Guarantor or any other guarantor or surety.

This Exhibit shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Guaranteed Obligations is rescinded or must otherwise be returned by the holders or any other Person upon the insolvency, bankruptcy or reorganization of the Maker or otherwise, all as though such payment had not been made.

     3. Waiver. Each Guarantor hereby waives (i) promptness and diligence, (ii) notice of acceptance and any other notice with respect to any of the Guaranteed Obligations and this Exhibit and any requirement that the holders exhaust any right or take any action against the Maker or any Guarantor or any other Person or any Collateral, (iii) any right to compel or direct any holder to seek payment or recovery of any amounts owed under this Exhibit from any one particular fund or source or to exhaust any right or take any action against the Maker or any Guarantor, any other Person or any Collateral, (iv) any requirement that any holder protect, secure, perfect or insure any security interest or Lien on any property subject thereto or exhaust any right to take any action against the Maker or any Guarantor, any other Person or any Collateral, and (v) any other defense available to any Guarantor. Each Guarantor agrees that the holders shall have no obligation to marshal any assets in favor of any Guarantor or against, or in payment of, any or all of the Obligations. Each Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated herein and that the waiver set forth in this Section 3 is knowingly made in contemplation of such benefits. Each Guarantor hereby waives any right to revoke this Exhibit, and acknowledges that this Exhibit is continuing in nature and applies to all Guaranteed Obligations, whether existing now or in the future.

     4. Continuing Guaranty; Assignments. This Exhibit is a continuing guaranty and shall (a) remain in full force and effect until the later of (i) the cash payment in full of the Guaranteed Obligations (other than indemnification obligations as to which no claim has been made) and all other amounts payable under this Exhibit and (ii) the Maturity Date, (b) be binding upon each Guarantor, its successors and assigns and (c) inure to the benefit of and be enforceable by the holders and their successors, pledgees, transferees and assigns.

     5. Subrogation. Each Guarantor will not exercise any rights that it may now or hereafter acquire against the Maker or any Guarantor or any other guarantor that arise from the existence, payment, performance or enforcement of the Guarantor’s obligations under this Exhibit, including any right of subrogation, reimbursement, exoneration, contribution or indemnification and any right to participate in any claim or remedy of the holders against the Maker or any

2

Guarantor or any other guarantor or any Collateral, whether or not such claim, remedy or right arises in equity or under contract, statute or common law, including the right to take or receive from the Maker or any Guarantor or any other guarantor, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security solely on account of such claim, remedy or right. If any amount shall be paid to any Guarantor in violation of the immediately preceding sentence, such amount shall be held in trust for the benefit of the holders shall forthwith be paid to the holders to be credited and applied to the Guaranteed Obligations and all other amounts payable under this Exhibit, whether matured or unmatured, in accordance with the terms of this Note, or to be held as Collateral for any Guaranteed Obligations or other amounts payable under this Exhibit thereafter arising. If (i) any Guarantor shall make payment to the holders of all or any part of the Guaranteed Obligations, (ii) all of the Guaranteed Obligations and all other amounts payable under this Exhibit shall be paid in full in cash and (iii) all commitments under the Subordinated Note Documents have been terminated, the holders will, at any Guarantor’s request and expense, execute and deliver to such Guarantor appropriate documents, without recourse and without representation or warranty, necessary to evidence the transfer by subrogation to such Guarantor of an interest in the Guaranteed Obligations resulting from such payment by such Guarantor.

     6. Conflict. Anything herein to the contrary notwithstanding, the obligations evidenced hereby, the exercise of any right or remedy with respect thereto, and certain of the rights of the holder hereof are subject to the provisions of the Intercreditor Agreement, dated as of the date hereof, among Ableco Finance LLC, as Collateral Agent, GMAC Commercial Finance LLC, as Administrative Agent, and the Payee. In the event of any conflict between the terms of the Subordination Agreement and this Agreement, the terms of the Subordination Agreement shall govern and control.

     7. Release of Guarantor. A Guarantor shall be released from all obligations under its Guaranty if (a) the Guarantor has sold all of its assets or the Company and its Subsidiaries have sold all the capital stock of the Guarantor owned by them, or (b) the Guarantor merges with or into or consolidates with or transfers all or substantially all of its assets to the Maker or another Guarantor.
