          The terms and provisions contained in the Notes shall constitute, and are hereby expressly made, a part of this Indenture and the Company, the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Note conflicts with the express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling.

          (b)     Global Notes. Global Notes shall be substantially in the form of Exhibit A attached hereto (including the Global Note Legend thereon and the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Definitive Notes shall be substantially in the form of Exhibit A attached hereto (but without the Global Note Legend thereon and without the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Each Global Note shall represent such of the outstanding Notes as shall be specified therein and each shall provide that it shall represent the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of

23

any increase or decrease in the aggregate principal amount of outstanding Notes represented thereby shall be made by the Trustee or the Notes Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.6 hereof.

Section 2.2 EXECUTION AND AUTHENTICATION

          Two Officers shall sign the Notes for the Company by manual or facsimile signature. In the case of Definitive Notes, such signatures may be imprinted or otherwise reproduced on such Notes. If an Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note shall nevertheless be valid. A Note shall not be valid until authenticated by the manual signature of the Trustee. The signature shall be conclusive evidence that the Note has been authenticated under this Indenture. The Trustee shall, upon a written order of the Company signed by an Officer (an “Authentication Order”), authenticate Notes for issuance up to the aggregate principal amount stated in such Authentication Order; provided that Notes authenticated for issuance on the Issue Date shall not exceed $135,000,000 in aggregate principal amount. The Trustee may appoint an authenticating agent acceptable to the Company to authenticate Notes. An authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with Holders or an Affiliate of the Company.

Section 2.3 REGISTRAR, PAYING AGENT AND DEPOSITARY

          The Company shall maintain an office or agency in the Borough of Manhattan, The City of New York, where Notes may be presented for registration of transfer or for exchange (“Registrar”) and an office or agency where Notes may be presented for payment (“Paying Agent”). The Registrar shall keep a register of the Notes and of their transfer and exchange. The Company may appoint one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company shall notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Company or any of its Subsidiaries may act as Paying Agent or Registrar. The Company initially appoints The Depository Trust Company (“DTC”) to act as Depositary with respect to the Global Notes. The Company initially appoints the Trustee to act as the Registrar and Paying Agent and to act as Notes Custodian with respect to the Global Notes.

Section 2.4 PAYING AGENT TO HOLD MONEY IN TRUST

          The Company shall require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal, premium or Liquidated Damages, if any, or interest on the Notes, and will notify the Trustee of any default by the Company in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Company or a Subsidiary) shall have no further liability for the money. If the Company or a Subsidiary acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or

24

reorganization proceedings relating to the Company, the Trustee shall serve as Paying Agent for the Notes.

Section 2.5 HOLDER LISTS

          The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders and shall otherwise comply with TIA § 312(a). If the Trustee is not the Registrar, the Company shall furnish, or shall cause the Registrar (if other than the Company) to furnish, to the Trustee at least seven Business Days before each Interest Payment Date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders of Notes and the Company shall otherwise comply with TIA § 312(a).

Section 2.6 TRANSFER AND EXCHANGE

          (a)     Transfer and Exchange of Global Notes. A Global Note may not be transferred except as a whole by the Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. Global Notes will not be exchanged by the Company for Definitive Notes unless:

               (i)     the Company delivers to the Trustee notice from the Depositary that (x) it is unwilling or unable to continue to act as Depositary and a successor Depositary is not appointed by the Company within 90 days after the date of such notice from the Depositary or (y) it is no longer a clearing agency registered under the Exchange Act;

               (ii)     the Company in its sole discretion determines that the Global Notes (in whole but not in part) should be exchanged for Definitive Notes and delivers a written notice to such effect to the Trustee (provided, there shall be no continuing Default or Event of Default); or

               (iii)     an Event of Default shall have occurred and be continuing with respect to the Notes and the Trustee has received a request from the Depositary or any Holder to issue Definitive Notes;

Upon the occurrence of any of the preceding events in (i), (ii) or (iii) above, Definitive Notes shall be issued in such names as the Depositary shall instruct the Trustee.

          In addition, beneficial interests in a Global Note may be exchanged for a Definitive Note upon request but only upon 20 days’ prior written notice by or on behalf of the Depositary in accordance with its customary procedures. Upon the occurrence of any of the events described in this Section 2.6(a), Definitive Notes shall be issued in such names as the Depositary shall instruct the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 2.7 and 2.10 hereof. Every Note, other than a Definitive Note, authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.6 or Section 2.7 or 2.10 hereof, shall be authenticated and delivered in the form of, and shall be, a Global Note. A Global Note may be exchanged for another Note only upon compliance with the applicable provisions of this Section 2.6(a) and Sections 2.7 and 2.10

          The Opinion of Counsel for the Company referenced above shall state substantially as follows:

               (A)     the Exchange Notes have been duly authorized and, when executed by the Company and authenticated by the Trustee in accordance with the provisions of this Indenture and delivered in exchange for Series A Notes in accordance with this Indenture and the Exchange Offer, will be entitled to the benefits of this Indenture, and will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, except as the enforceability thereof may be limited by bankruptcy, insolvency, reorganization, receivership, moratorium or other laws affecting creditors’ rights (including, without limitation, the effect of statutory and other laws regarding fraudulent conveyances, fraudulent transfers and preferential transfers) and as may be limited by the exercise of judicial discretion and the application of principles of equity including, without limitation, requirements of good faith, fair dealing, conscionability and materiality (regardless of whether the enforceability of the Exchange Notes is considered in a proceeding in equity or at law); and

               (B)     when the Exchange Notes are issued and executed by the Company and authenticated by the Trustee in accordance with the provisions of this Indenture and delivered in exchange for Series A Notes in accordance with this Indenture and the Exchange Offer, the Guarantees by the Guarantors endorsed thereon will be entitled to the benefits of this Indenture, and will constitute valid and binding obligations of the Guarantors, enforceable against the Guarantors in accordance with their terms, except as the enforceability thereof may be limited by bankruptcy, insolvency, reorganization, receivership, moratorium or other laws affecting creditors’ rights (including, without limitation, the effect of statutory and other laws regarding fraudulent conveyances, fraudulent transfers and preferential transfers) and as may be limited by the exercise of judicial discretion and the application of principles of equity including, without limitation, requirements of good faith, fair dealing, conscionability and materiality (regardless of whether the enforceability of the Guarantees is considered in a proceeding in equity or at law).

34

               (B)     Notwithstanding the foregoing, any Global Note or Definitive Note issued pursuant to subparagraphs (b)(4), (c)(2), (c)(3), (d)(2), (d)(3), (e)(2), (e)(3) or (f) to this Section 2.6 (and all Notes issued in exchange therefor or substitution thereof) shall not bear the Private Placement Legend.

At such time as all beneficial interests in a particular Global Note have been exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or cancelled in whole and not in part, each such Global Note shall be returned to or retained and cancelled by the Trustee in accordance with Section 2.11 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the principal amount of Notes represented by such Global Note shall be reduced accordingly and an endorsement may be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note shall be increased accordingly and an endorsement may be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such increase.

          (i)      General Provisions Relating to Transfers and Exchanges.

                (i)     To permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Global Notes and Definitive Notes upon receipt of an Authentication Order.

                (ii)     No service charge shall be made to a holder of a beneficial interest in a Global Note or to a Holder of a Definitive Note for any registration of transfer or

36

exchange, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.10, 3.6, 4.13 or 4.16 hereof).

               (iii)     The Registrar shall not be required to register the transfer of or exchange any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part.

               (iv)     All Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes shall be the valid obligations of the Company, evidencing the same Indebtedness, and entitled to the same benefits under this Indenture, as the Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange.

               (v)     The Company shall not be required (A) to issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business 15 days before the day of any selection of Notes for redemption under Section 3.2 hereof and ending at the close of business on the day of selection, (B) to register the transfer of or to exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part or (C) to register the transfer of or to exchange a Note between an Interest Record Date and the next succeeding Interest Payment Date.

               (vi)     Prior to due presentment for the registration of a transfer of any Note, the Trustee, any Agent and the Company may deem and treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and interest on such Notes and for all other purposes, and none of the Trustee, any Agent or the Company shall be affected by notice to the contrary.

               (vii)     None of the Company, the Trustee, the Paying Agent or the Registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of the Global Notes or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

          Notwithstanding anything herein to the contrary, as to any certifications and certificates delivered to the Registrar pursuant to this Section 2.6, the Registrar’s duties shall be limited to confirming that any such certifications and certificates delivered to it are in the form of Exhibits A, B, C, D and E attached hereto. The Registrar shall not be responsible for confirming the truth or accuracy of representations made in any such certifications or certificates.

Section 2.7 REPLACEMENT NOTES

          If any mutilated Note is surrendered to the Trustee or the Company and the Trustee and the Company receive evidence (which evidence may be from the Trustee) to their

37

satisfaction of the destruction, loss or theft of any Note, the Company shall issue and the Trustee, upon receipt of an Authentication Order, shall authenticate a replacement Note if the Trustee’s and the Company’s requirements are met. If required by the Trustee or the Company, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Company may charge for its expenses in replacing a Note. Every replacement Note is an additional obligation of the Company and shall be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder.

Section 2.8 OUTSTANDING NOTES

          The Notes outstanding at any time are all the Notes authenticated by the Trustee (including any Note represented by a Global Note) except for those cancelled by it or at its direction, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.8 as not outstanding. Except as set forth in Section 2.9 hereof, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note. If a Note is replaced pursuant to Section 2.7 hereof, such Note, together with the Guarantee of that particular Note endorsed thereon, ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser. If the principal amount of any Note is considered paid under Section 4.1 hereof, it ceases to be outstanding and interest on it ceases to accrue. If the Paying Agent (other than the Company, a Subsidiary or an Affiliate of any thereof) holds, on a redemption date or the maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes shall be deemed to be no longer outstanding and shall cease to accrue interest.

Section 2.9 TREASURY NOTES

          In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company, shall be considered as though not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes that the Trustee knows are so owned shall be so disregarded.

Section 2.10 TEMPORARY NOTES

          Until certificates representing Notes are ready for delivery, the Company may prepare and the Trustee, upon receipt of an Authentication Order, shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of Definitive Notes but may have variations that the Company considers appropriate for temporary Notes and as shall be reasonably acceptable to the Trustee. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate Definitive Notes in exchange for temporary Notes. Holders of temporary Notes shall be entitled to all of the benefits of this Indenture.

Section 2.11 CANCELLATION

          The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee, or at the direction of the Trustee, the

38

Registrar or the Paying Agent (other than the Company or an Affiliate of the Company), and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and shall destroy cancelled Notes (subject to the record retention requirement of the Exchange Act). Certification of the destruction of all cancelled Notes shall be delivered to the Company. The Company may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation.

Section 2.12 DEFAULTED INTEREST

          Any interest on any Note which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date plus, to the extent lawful, any interest payable on the defaulted interest at the rate and in the manner provided in Section 4.1 hereof and in the Note (herein called “Defaulted Interest”) shall forthwith cease to be payable to the registered holder on the relevant Interest Record Date, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause (1) or (2) below:

          (1)     The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Notes are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee and the Paying Agent in writing of the amount of Defaulted Interest proposed to be paid on each Note and the date of the proposed payment, and at the same time the Company shall deposit with the Paying Agent an amount of cash equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements reasonably satisfactory to the Paying Agent for such deposit prior to the date of the proposed payment, such cash when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as provided in this clause (1). Thereupon the Paying Agent shall fix a “Special Record Date” for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Paying Agent of the notice of the proposed payment. The Paying Agent shall promptly notify the Company and the Trustee of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder at its address as it appears in the Note register maintained by the Registrar not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the persons in whose names the Notes (or their respective predecessor Notes) are registered on such Special Record Date and shall no longer be payable pursuant to the following clause (2).

          (2)     The Company may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee and the Paying Agent of the proposed payment pursuant to this clause, such manner shall be deemed practicable by the Trustee and the Paying Agent.

          Subject to the foregoing provisions of this Section 2.12, each Note delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Note.

39

Section 2.13 CUSIP NUMBERS

          The Company in issuing the Notes may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee of any change in the “CUSIP” numbers.

Section 2.14 ISSUANCE OF ADDITIONAL NOTES

          The Company may, subject to Section 4.7 hereof and applicable law, issue Additional Notes under this Indenture. The Notes issued on the Issue Date and any additional Notes subsequently issued shall be treated as a single class for all purposes under this Indenture.

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

          The Trustee shall promptly notify the Company 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 in denominations of larger than $1,000 selected shall be in 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 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 Notes called for redemption also apply to portions of Notes called for redemption.

40

Section 3.3 NOTICE OF REDEMPTION

          Subject to the provisions of Section 3.7 hereof, at least 30 days but not more than 60 days before a Redemption Date, the Company shall mail or cause to be mailed, by first class mail, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address.

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

          (a)     the Redemption Date;

          (b)     the redemption price;

          (c)     if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, on or after the Redemption Date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion shall be issued upon cancellation of the original Note;

          (d)     the name and address of the Paying Agent;

          (e)     that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price;

          (f)     that, unless the Company defaults in making such redemption payment, interest on Notes called for redemption ceases to accrue on and after the Redemption Date;

          (g)     the paragraph of the Notes and/or Section of this Indenture pursuant to which the Notes called for redemption are being redeemed; and

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

          At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at its expense; provided, however, that the Company shall have delivered to the Trustee, at least 45 days prior to the Redemption Date (unless a shorter period shall be acceptable to the Trustee), an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph.

          Failure to send such notice in the manner herein provided to the Holder of any particular Note designated for redemption as a whole or in part, or any defect in the notice to such Holder, shall not affect the validity of the proceedings for the redemption of any other Notes or portions thereof.

Section 3.4 EFFECT OF NOTICE OF REDEMPTION

          Once notice of redemption is mailed in accordance with Section 3.3 hereof, Notes called for redemption become irrevocably due and payable on the Redemption Date at the redemption price. A notice of redemption may not be conditional.

Section 3.5 DEPOSIT OF REDEMPTION PRICE

          On or prior to the Redemption Date, the Company shall deposit with the Trustee or with the Paying Agent immediately available funds sufficient to pay the redemption price of and accrued and unpaid interest (and Liquidated Damages, if any) on all Notes to be redeemed on that date. The Trustee or the Paying Agent shall promptly return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption price of, and accrued and unpaid interest (and Liquidated Damages, if any) on, all Notes to be redeemed.

          If the Company complies with the provisions of the preceding paragraph, on and after the Redemption Date, interest shall cease to accrue on the Notes or the portions of Notes called for redemption. If a Note is redeemed on or after an Interest Record Date but on or prior to the related Interest Payment Date, then any accrued and unpaid interest (and Liquidated Damages, if any) shall be paid to the Person in whose name such Note was registered at the close of business on such Interest Record Date. If any Note called for redemption shall not be so paid upon surrender for redemption because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the Redemption Date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.1 hereof.

Section 3.6 NOTES REDEEMED IN PART

          The Company and the Guarantors may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such additional designations; provided that no such designation or rescission shall in any manner relieve the Company and the Guarantors of their obligation to maintain an office or agency in the Borough of Manhattan, The City of New York.

          Except as set forth in this Section 4.7, the Company shall not, and shall not permit any of its Subsidiaries to, directly or indirectly, issue, assume, guaranty, incur, become directly or indirectly liable with respect to (including as a result of an Acquisition), or otherwise become responsible for, contingently or otherwise (individually and collectively, to “incur” or, as appropriate, an “incurrence”), any Indebtedness (including Disqualified Capital Stock and Acquired Indebtedness), other than Permitted Indebtedness.

          Notwithstanding the foregoing, if:

          (1)     no Default or Event of Default shall have occurred and be continuing at the time of, or would occur after giving effect on a pro forma basis to, such incurrence of Indebtedness; and

          (2)     on the date of such incurrence (the “Incurrence Date”), the Company’s Interest Coverage Ratio for the Reference Period immediately preceding the Incurrence Date, after giving effect on a pro forma basis to such incurrence of such Indebtedness and, to the extent

45

set forth in the definition of Interest Coverage Ratio, the use of proceeds thereof, would be at least 2.0 to 1.0 (the “Debt Incurrence Ratio”);

then the Company and the Guarantors may incur such Indebtedness (including Disqualified Capital Stock and Acquired Indebtedness).

          Indebtedness (including Disqualified Capital Stock) of any Person which is outstanding at the time such Person becomes one of the Company’s Subsidiaries (including upon designation of any Person as a Subsidiary) or is merged with or into or consolidated with the Company or one of its Subsidiaries shall be deemed to have been incurred at the time such Person becomes or is designated one of the Company’s Subsidiaries or is merged with or into or consolidated with the Company or one of its Subsidiaries, as applicable.

          Notwithstanding any other provision of this Section 4.7, but only to avoid duplication, a guarantee by a Guarantor of the Company’s Indebtedness or of the Indebtedness of another Guarantor incurred in accordance with the terms of this Indenture (other than guarantees with respect to Indebtedness incurred pursuant to clause (b) of the definition of Permitted Indebtedness) made at the time such Indebtedness was incurred or, if later, at the time the guarantor thereof became a Guarantor will not constitute a separate incurrence, or amount outstanding, of Indebtedness. Upon each incurrence, the Company may designate pursuant to which provision of this Section 4.7 (including which portion of the definition of Permitted Indebtedness) such Indebtedness is being incurred and the Company may subdivide an amount of Indebtedness and such Indebtedness shall not be deemed to have been incurred or outstanding under any other provision of this Section 4.7 (or other portion of the definition of Permitted Indebtedness) (except that all Indebtedness outstanding under the Credit Agreement on the original Issue Date shall be deemed to have been incurred pursuant to clause (f) of the definition of Permitted Indebtedness and all Indebtedness under the Notes, the Guarantees and this Indenture shall be deemed to have been incurred pursuant to clause (a) of the definition of Permitted Indebtedness).

Section 4.8 LIMITATION ON LIENS

          The Company shall not and shall not permit any of its Subsidiaries to, create, incur, assume or suffer to exist any Lien of any kind securing Indebtedness, other than Permitted Liens, upon any of their respective assets (including, without limitation, all real, tangible or intangible property) now owned or acquired on or after the date of this Indenture or upon any income or profits therefrom or convey any right to receive income therefrom unless the Company provides, and causes its Subsidiaries to provide, concurrently therewith, that the Notes and the applicable Guarantees are equally and ratably so secured; provided that if such Indebtedness is Subordinated Indebtedness, the Lien securing such Subordinated Indebtedness shall be contractually subordinate and junior to the Lien securing the Notes (and any related applicable Guarantees) with the same relative priority as such Subordinated Indebtedness shall have with respect to the Notes (and any related applicable Guarantees) and provided, further, that this clause shall not be applicable to any Liens securing any such Indebtedness which became the Company’s Indebtedness pursuant to a transaction subject to Section 5.1 or which constitutes Acquired Indebtedness and which in either case were in existence at the time of such transaction (unless such Indebtedness was incurred or such Lien created in connection with or in contemplation of, such transaction), so long as such Liens do not extend to or cover any of the Company’s property or assets or any property or assets of any of the Company’s Subsidiaries other than property or assets acquired in such transaction.

46

Section 4.9 LIMITATION ON RESTRICTED PAYMENTS

          The Company shall not, and shall not permit any of its Subsidiaries to, directly or indirectly, make any Restricted Payment if, after giving effect to such Restricted Payment on a pro forma basis:

          (1)     a Default or an Event of Default shall have occurred and be continuing;

          (2)     the Company is not permitted to incur at least $1.00 of additional Indebtedness pursuant to the Debt Incurrence Ratio in Section 4.7 hereof; and

          (3)     the aggregate amount of all Restricted Payments made by the Company and its Subsidiaries, on and after the Issue Date, would exceed, without duplication, the sum of:

            The foregoing clauses (2) and (3) of the immediately preceding paragraph of this Section 4.9, however, shall not prohibit:

47

The foregoing clauses (1), (2) and (3) of the immediately preceding paragraph of this Section 4.9 shall not prohibit:

          The full amount of any Restricted Payment made pursuant to the foregoing clauses (w), (x) and (z) (but not pursuant to clause (y)) of the immediately preceding sentence, however, shall be counted as Restricted Payments made for purposes of the calculation of the aggregate amount of Restricted Payments available to be made referred to in clause (3) of the first paragraph of this Section 4.9.

          For purposes of this Section 4.9, the amount of any Restricted Payment made or returned, if other than in cash, shall be the fair market value thereof, as determined in the good faith reasonable judgment of the Company’s Board of Directors, at the time made or returned, as applicable. Additionally, within 10 Business Days of each Restricted Payment in excess of $500,000 that is not a Restricted Investment, the Company shall deliver an Officers’ Certificate to the Trustee describing in reasonable detail the nature of such Restricted Payment, stating the amount of such Restricted Payment, stating in reasonable detail the provisions of this Indenture pursuant to which such Restricted Payment was made and certifying that such Restricted Payment was made in compliance with the terms of this Indenture.

Section 4.10 LIMITATION ON DIVIDENDS AND OTHER PAYMENT RESTRICTIONS AFFECTING SUBSIDIARIES

          The Company shall not, and shall not permit any of its Subsidiaries to, directly or indirectly, create, assume or suffer to exist any consensual restriction on the ability of any of their Subsidiaries to pay dividends or make other distributions to or on behalf of, or to pay any obligation to or on behalf of, or otherwise to transfer assets or property to or on behalf of, or make or pay loans or advances to or on behalf of, the Company or any of its Subsidiaries, except:

          (1)     restrictions imposed by the Notes, the Guarantees or this Indenture or by the Company’s other Indebtedness (which may also be guaranteed by the Guarantors) ranking pari passu with the Notes or the Guarantees, as applicable; provided, that such restrictions are no

48

more restrictive in any material respect than those imposed by this Indenture, the Guarantees and the Notes;

          (2)     restrictions imposed by applicable law;

          (3)     existing restrictions as of the Issue Date, including those under Existing Indebtedness;

          (4)     restrictions under any Acquired Indebtedness or Capital Stock of a Person acquired by the Company or any Subsidiary not incurred in violation of this Indenture or any agreement relating to any property, asset, or business acquired by the Company, or any of its Subsidiaries, which restrictions, in each case, existed at the time of acquisition, were not put in place in connection with or in anticipation of such acquisition and are not applicable to any Person, other than the Person acquired, or to any property, asset or business, other than the property, assets and business so acquired;

          (5)     any restriction imposed by Indebtedness incurred under the Credit Agreement pursuant to clause (f) of the definition of “Permitted Indebtedness;” provided, that such restriction or requirement is no more restrictive in any material respect than that imposed by the Credit Agreement on the Issue Date;

          (6)     restrictions with respect solely to any of the Company’s Subsidiaries imposed pursuant to a binding agreement which has been entered into for the sale or disposition of all of the Equity Interests or assets of such Subsidiary; provided, that such restrictions apply solely to the Equity Interests or assets of such Subsidiary which are being sold;

          (7)     restrictions on transfer contained in Purchase Money Indebtedness incurred pursuant to Section 4.7 hereof or clause (g) of the definition of “Permitted Indebtedness;” provided, that such restrictions relate only to the transfer of the property acquired, constructed, installed, improved or leased with the proceeds of such Purchase Money Indebtedness;

          (8)     in connection with and pursuant to permitted refinancings, the replacements of restrictions imposed pursuant to clauses (1), (3), (4) or (7) or this clause (8) of this paragraph that are not more restrictive in any material respect than those being replaced and do not apply to any other Person or assets than those that would have been covered by the restrictions in the Indebtedness so refinanced; and

          (9)     any other customary provisions arising or agreed to in the ordinary course of business consistent with past practice, not relating to Indebtedness or Capital Stock, that do not individually or in the aggregate detract from the value of the assets of the Company or any Guarantor.

          Notwithstanding the foregoing, (a) leases, licenses or contracts entered into in the ordinary course of business, consistent with industry practice may be subject to customary restrictions on subletting or assignment, and (b) any asset subject to a Lien which is not prohibited to exist with respect to such asset pursuant to the terms of this Indenture, may be subject to customary restrictions on the transfer or disposition thereof pursuant to such Lien.

          Nothing contained in this Section 4.10 shall prevent the Company or any Subsidiary from creating, incurring, assuming or suffering to exist any Lien otherwise permitted pursuant to Section 4.8 hereof.

49

Section 4.11 LIMITATION ON TRANSACTIONS WITH AFFILIATES

          Neither the Company nor any of its Subsidiaries shall be permitted on or after the Issue Date to enter into any contract, agreement, arrangement or transaction with any Affiliate (an “Affiliate Transaction”), or any series of related Affiliate Transactions (other than Exempted Affiliate Transactions and transactions subject to written agreements to which the Company or any Subsidiary is a party as of the Issue Date), unless (1) it is determined that the terms of such Affiliate Transaction are fair and reasonable to the Company, and no less favorable to the Company than could have been obtained in an arm’s length transaction with a non-Affiliate, and (2) if involving consideration to either party of $5,000,000 or more, such Affiliate Transaction(s) has been approved by a majority of the members of the Company’s Board of Directors that are disinterested in such transaction, and (3) if involving consideration to either party of $10,000,000 or more (or if no members of the Board of Directors of the Company are disinterested in such transaction), the Company and/or its applicable Subsidiaries, prior to the consummation thereof, obtain a written favorable opinion as to the fairness of such transaction to the Company from a financial point of view from an independent investment banking firm of national reputation in the United States or, if pertaining to a matter for which such investment banking firms do not customarily render such opinions, an appraisal or valuation firm of national reputation in the United States.

Section 4.12 LIMITATION ON SALE OF ASSETS AND SUBSIDIARY STOCK

          (a) The Company shall not, and shall not permit any of the Company’s Subsidiaries to, in one or a series of related transactions, convey, sell, transfer, assign or otherwise dispose of, directly or indirectly, any of their property, business or assets, including by merger or consolidation (in the case of a Subsidiary of the Company), and including any sale or other transfer or issuance (but not an issuance, in the case of an Unrestricted Subsidiary) of any Equity Interests of any of the Company’s Subsidiaries or Unrestricted Subsidiaries, whether by the Company or one of its Subsidiaries and including any sale-leaseback transaction (any of the foregoing, an “Asset Sale”), unless, with respect to any Asset Sale or related series of Asset Sales involving securities, property or assets with an aggregate fair market value in excess of $5,000,000 (an Asset Sale (including a series of related Asset Sales) of less than $5,000,000 shall not be subject to this Section 4.12), (a) at least 75% (or 50%, in the case of the sale of the Transportation Management System business of the Company) of the total consideration for such Asset Sale or series of related Asset Sales consists of cash or Cash Equivalents, and (b) the Company’s Board of Directors determines in good faith that the Company will be receiving or such Subsidiary will be receiving, as applicable, fair market value for such Asset Sale. Solely for purposes of the preceding sentence, “cash and Cash Equivalents” shall include (i) any of the Company’s or the Company’s Subsidiaries liabilities (as shown on the Company’s or the Company’s Subsidiaries’ most recent balance sheet) other than (x) Indebtedness under the Company’s Credit Agreement, (y) contingent liabilities and (z) liabilities that are by their terms subordinated to the Notes or any Guarantee assumed by the purchaser; provided, that, in each case, the Company and its Subsidiaries are fully released from obligations in connection therewith, (ii) assets for use in a Related Business or Equity Interests of a Person that becomes a Subsidiary which is primarily engaged in a Related Business, (iii) Indebtedness incurred under the Credit Agreement that is assumed by a transferee; provided that the Company and its Subsidiaries are fully released from obligations in connection with the amounts assumed and the assumed Indebtedness permanently reduced the Indebtedness under the Credit Agreement (and in the case of a revolver or similar arrangement that makes credit available, such commitment is permanently reduced by such amount) provided further, that if Indebtedness under the Credit Agreement in the form of letters of credit are assumed by the purchaser in connection with the

50

sale of the Transportation Management Systems business of the Company, and the Company and the Company’s Subsidiaries are fully released from obligations in connection with such letters of credit, then the Credit Agreement need not be permanently reduced by the amount of such assumed letters of credit, and (iv) property that within 30 days of such Asset Sale is converted into cash or Cash Equivalents; provided, that such cash and Cash Equivalents shall be treated as Net Cash Proceeds attributable to the original Asset Sale for which such property was received.

          (b) Within 365 days following such Asset Sale, Net Cash Proceeds therefrom (the “Asset Sale Amount”) shall be:

          (1) used (i) to retire Purchase Money Indebtedness secured by the asset which was the subject of the Asset Sale; or (ii) to retire and permanently reduce Indebtedness incurred under the Credit Agreement; provided, that in the case of a revolver or similar arrangement that makes credit available, such commitment is permanently reduced by such amount; or

          (2) used to make (i) capital expenditures or (ii) investments in assets and property (other than notes, bonds, obligations and securities, except in connection with the acquisition of a Person in a Related Business that becomes a Subsidiary that, if required under this Indenture, becomes a Guarantor) which in the good faith reasonable judgment of the Company’s Board of Directors will immediately constitute or be a part of or useful in a Related Business of the Company or such Subsidiary (if it continues to be a Subsidiary) immediately following such transaction; or the Company shall, within such 365-day period, enter into a legally binding agreement to apply such Net Cash Proceeds as described in this clause (b) within six months after such agreement is entered into and apply such Net Cash Proceeds in accordance with the provisions of this clause (b); provided, that if such agreement terminates, the Company shall have until the later of (i) 90 days after the date of such termination and (ii) 365 days after the date of the Asset Sale resulting in such Net Cash Proceeds to effect such application.

          (c) The accumulated Net Cash Proceeds from Asset Sales and from any Event of Loss not applied as set forth in Section 4.12(b) shall constitute “Excess Proceeds.” Pending the final application of any Net Cash Proceeds, the Company may temporarily reduce revolving credit borrowings or otherwise invest or use for general corporate purposes (other than Restricted Payments that are not solely Restricted Investments) the Net Cash Proceeds in any manner that is not prohibited by this Indenture.

          (d) When the Excess Proceeds equal or exceed $15,000,000, within 20 Business Days the Company shall offer to repurchase the Notes, together with any other Indebtedness ranking on a parity with the Notes and with similar provisions requiring the Company to make an offer to purchase such Indebtedness with the proceeds from such Asset Sale pursuant to a cash offer (subject only to conditions required by applicable law, if any), pro rata in proportion to the respective principal amounts of such Indebtedness (or accreted values in the case of Indebtedness issued with an original issue discount) and the Notes (the “Asset Sale Offer”) at a purchase price of 100% of the principal amount (or accreted value in the case of Indebtedness issued with an original issue discount) (the “Asset Sale Offer Price”) together with accrued and unpaid interest and Liquidated Damages, if any, to the date of payment. The Asset Sale Offer shall remain open for at least 20 Business Days following its commencement (the “Asset Sale Offer Period”).

          (e) Upon expiration of the Asset Sale Offer Period, the Company shall apply an amount equal to the Excess Proceeds (the “Asset Sale Offer Amount”) plus an amount equal to

51

accrued and unpaid interest and Liquidated Damages, if any, to the purchase of all Indebtedness properly tendered in accordance with the provisions hereof (on a pro rata basis if the Asset Sale Offer Amount is insufficient to purchase all Indebtedness so tendered) at the Asset Sale Offer Price (together with accrued and unpaid interest and Liquidated Damages, if any, to the day of payment). To the extent that the aggregate amount of Notes and such other pari passu Indebtedness tendered pursuant to an Asset Sale Offer is less than the Asset Sale Offer Amount, the Company may use any remaining Net Cash Proceeds as otherwise permitted by this Indenture. Following the consummation of each Asset Sale Offer, the Excess Proceeds amount shall be reset to zero.

          (f) Notwithstanding, and without complying with, the provisions of this Section 4.12:

          (1) the Company may and its Subsidiaries may, in the ordinary course of business, (a) convey, sell, transfer, assign or otherwise dispose of inventory and other assets acquired and held for resale in the ordinary course of business and (b) liquidate Cash Equivalents;

          (2) the Company may and its Subsidiaries may convey, sell, transfer, assign or otherwise dispose of assets pursuant to and in accordance with Section 5.1;

          (3) the Company may and its Subsidiaries may sell or dispose of damaged, worn out or other obsolete personal property in the ordinary course of business so long as such property is no longer necessary for the proper conduct of the Company’s business or the business of such Subsidiary, as applicable;

          (4) the Company may and its Subsidiaries may convey, sell, transfer, assign or otherwise dispose of assets to the Company or any of the Subsidiaries;

          (5) the Company may and each of its Subsidiaries may surrender or waive contract rights or may settle, release or surrender tort or other litigation claims in the ordinary course of business or grant Liens not prohibited by this Indenture; and

          (6) the Company may and its Subsidiaries may make Permitted Investments (other than pursuant to clause (a) of the definition thereof) and Restricted Investments that are not prohibited by Section 4.9 hereof.

          (g) All Net Cash Proceeds from an Event of Loss (other than the proceeds of any business interruption insurance) shall be reinvested or used as otherwise provided above in clauses (1) or (2) of Section 4.12(b).

          (h) Any Asset Sale Offer shall be made in compliance with all applicable laws, rules, and regulations, including, if applicable, Regulation 14E of the Exchange Act and the rules and regulations thereunder and all other applicable federal and state securities laws. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.12, the Company’s compliance or the compliance of any of its Subsidiaries with such laws and regulations shall not in and of itself cause a breach of the Company’s obligations under this Section 4.12.

          If the payment date in connection with an Asset Sale Offer hereunder is on or after an Interest Record Date and on or before the associated Interest Payment Date, any accrued and unpaid interest (and Liquidated Damages, if any, due on such Interest Payment Date) will be

52

paid to the Person in whose name a Note is registered at the close of business on such Interest Record Date.

Section 4.13 LIMITATION ON SALE-LEASEBACK TRANSACTIONS

          The Company will not, and will not permit any of its Subsidiaries to, enter into any sale-leaseback transaction (other than a sale-leaseback transaction between the Company and one or more Guarantors or among Guarantors); provided that the Company and the Guarantors may enter into a sale-leaseback transaction if:

          (1) the Company or such Guarantor could have (a) incurred Indebtedness in an amount equal to the Attributable Indebtedness relating to such sale-leaseback transaction under the Debt Incurrence Ratio in the second paragraph of Section 4.7 hereof and (b) incurred a Lien to secure such Indebtedness pursuant to Section 4.8 hereof;

          (2) the gross cash proceeds of such sale-leaseback transaction are at least equal to the fair market value, as determined in good faith by the Board of Directors and set forth in an Officers’ Certificate delivered to the Trustee, of the property that is the subject of such sale-leaseback transaction; and

          (3) the transfer of assets in such sale-leaseback transaction is permitted by, and the Company applies the proceeds of such transaction in compliance with, Section 4.12 hereof.

Section 4.14 REPURCHASE OF NOTES AT THE OPTION OF THE HOLDER UPON A CHANGE OF CONTROL

          In the event that a Change of Control has occurred, each Holder of Notes will have the right, at such Holder’s option, pursuant to an offer (subject only to conditions required by applicable law, if any) by the Company (the “Change of Control Offer”), to require the Company to repurchase all or any part of such Holder’s Notes (provided, that the principal amount of such Notes must be $1,000 or an integral multiple thereof) at a cash price equal to 101% of the principal amount thereof (the “Change of Control Purchase Price”), in each case, together with accrued and unpaid interest (and Liquidated Damages, if any) thereon, to the Change of Control Purchase Date.

          The Change of Control Offer shall be made within 30 Business Days following a Change of Control and shall remain open for at least 20 Business Days and not more than 30 Business Days following its commencement (the “Change of Control Offer Period”). Upon expiration of the Change of Control Offer Period, the Company promptly shall purchase all Notes properly tendered in response to the Change of Control Offer.

          On or before the Change of Control Purchase Date, the Company shall:

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

          (2) deposit with the Paying Agent cash sufficient to pay the Change of Control Purchase Price (together with accrued and unpaid interest and Liquidated Damages, if any) of all Notes so tendered; and

53

          (3) deliver to the Trustee the Notes so accepted together with an Officers’ Certificate listing the Notes or portions thereof being purchased by the Company.

          The Paying Agent promptly will pay the Holders of Notes so accepted an amount equal to the Change of Control Purchase Price (together with accrued and unpaid interest and Liquidated Damages, if any) and the Trustee promptly will authenticate and deliver to such Holders a new Note equal in principal amount to any unpurchased portion of the Note surrendered. Any Notes not so purchased will be delivered promptly by the Company to the Holder thereof. The Company publicly will announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Purchase Date.

          Any Change of Control Offer will be made in compliance with all applicable laws, rules and regulations, including, if applicable, Regulation 14E under the Exchange Act and the rules thereunder and all other applicable federal and state securities laws. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.14, the Company’s compliance with such laws and regulations shall not in and of itself cause a breach of its obligations under this Section 4.14.

          If the Change of Control Purchase Date is on or after an Interest Record Date and on or before the associated Interest Payment Date, any accrued and unpaid interest (and Liquidated Damages, if any) due on such Interest Payment Date will be paid to the Person in whose name a Note is registered at the close of business on such Interest Record Date.

          The Company shall not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control made by the Company and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer.

Section 4.15 SUBSIDIARY GUARANTORS

          All of the Company’s present and future domestic Subsidiaries (other than the Non-Guarantor Subsidiaries unless and until the revenue of the Non-Guarantor Subsidiaries, in the aggregate, exceeds 1% of the revenue of the Company and its Consolidated Subsidiaries, or the book value of the assets of the Non-Guarantor Subsidiaries, in the aggregate, exceeds 1% of the book value of the assets of the Company and its Consolidated Subsidiaries) jointly and severally will guaranty all principal, premium, if any, and interest on the Notes on a senior basis and deliver to the Trustee an opinion of counsel that such guaranty has been duly authorized, executed and delivered if (1) any of the Company’s Subsidiaries that is not a Guarantor guarantees any of the Company’s other Indebtedness or any other Indebtedness of any Subsidiary, or the Company or any of the Company’s Subsidiaries, individually or collectively, pledges more than 65% of the Voting Equity Interests of any Subsidiary that is not a Guarantor to a lender to secure the Company’s Indebtedness or any Indebtedness of any Subsidiary or (2) any individual domestic Subsidiary has revenue that, in the aggregate, exceeds 1% of the revenue of the Company and its Consolidated Subsidiaries, taken as a whole, or the book value of the assets of any individual domestic Subsidiary, in the aggregate, exceeds 1% of the book value of the assets of the Company and its Consolidated Subsidiaries, taken as a whole).

          (d) a default occurs and is continuing (after giving effect to any waivers, amendments, applicable grace periods or any extension of any maturity date) under the Indebtedness of the Company or the Indebtedness of any the Company’s Subsidiaries with an aggregate amount outstanding in excess of $10,000,000 (i) resulting from the failure to pay principal of or interest on such Indebtedness; or (ii) if as a result of such default, the maturity of such Indebtedness has been accelerated prior to its stated maturity;

Section 6.2 ACCELERATION

          (a) If an Event of Default occurs and is continuing (other than an Event of Default specified in clause (g) or (h) of Section 6.1 under this Indenture) then in every such case, unless the principal of all of the Notes shall have already become due and payable, either the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding, by written notice to the Company (and to the Trustee if such notice is given by the Holders), may, and the Trustee at the request of such Holders shall, declare the principal of, premium, if any, and accrued interest (and Liquidated Damages, if any) on the Notes to be due and payable immediately. Upon a declaration of acceleration, such principal of, premium, if any, and accrued interest (and Liquidated Damages, if any) on the Notes shall be immediately due and payable. If an Event of Default specified in clause (g) or (h) of Section 6.1 occurs, all principal and accrued interest (and Liquidated Damages, if any) thereon will be immediately due and payable on all outstanding Notes without any declaration or other act on the part of the Trustee or the Holders. In the event a declaration of acceleration because of an Event of Default set forth in clause (d) of Section 6.1 solely by virtue of a default under any Indebtedness has occurred and is continuing, such declaration of acceleration shall be automatically rescinded and annulled if the event of default triggering such Event of Default pursuant to clause (d) of Section 6.1 shall be remedied, or cured or waived by the holders of the relevant Indebtedness, within 60 days after such event of default, provided that no judgment or decree for the payment of money due on the Notes has been obtained by the Trustee.

          (b) Except as provided in Section 6.2(c), at any time after a declaration of acceleration has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter provided in this Article VI, the Holders of not less than a majority in aggregate principal amount of then outstanding Notes, by written notice to the Company and the Trustee, may rescind, on behalf of all Holders, any such declaration of acceleration if:

          (1) the Company has paid or deposited with the Trustee cash sufficient to pay: (a) all overdue interest and Liquidated Damages, if any, on all Notes; (b) the principal of (and premium, if any, applicable to) any Notes which would become due other than by reason of such declaration of acceleration, and interest thereon at the rate borne by the Notes; (c) to the extent that payment of such interest is lawful, interest upon overdue interest at the rate borne by the Notes; and (d) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee and its agents and counsel, and all other amounts due the Trustee under Section 7.7 hereof; and

          (2) all Events of Default, other than the non-payment of the principal of, premium, if any, and interest (and Liquidated Damages, if any) on the Notes which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 6.4 hereof.

          (c) Notwithstanding clause (b) of this Section 6.2, no waiver shall be effective against any Holder for any Event of Default or event which with notice or lapse of time or both would be an Event of Default with respect to any covenant or provision which cannot be

58

modified or amended without the consent of the Holder of each outstanding Note affected thereby, unless all such affected Holders agree, in writing, to waive such Event of Default or other event. No such waiver shall cure or waive any subsequent default or impair any right consequent thereon.

Section 6.3 OTHER REMEDIES

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

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

Section 6.4 WAIVER OF PAST DEFAULTS

          Subject to Section 6.7 hereof, the Holders of a majority in principal amount of the outstanding Notes by written notice to the Company and to the Trustee, may, on behalf of all Holders, waive any existing or past Default or Event of Default hereunder and its consequences under this Indenture, except a default:

          (1) with respect to any provision of this Indenture requiring a supermajority approval to amend, which Default may only be waived by such a supermajority;

          (2) in the payment of principal of, premium, if any, Liquidated Damages, if any, or interest on any Note not yet cured as specified in clauses (a) and (b) of Section 6.1 hereof;

          (3) in respect of a covenant or provision hereof which, under Article IX, cannot be modified or amended without the consent of the Holder of each outstanding Note affected, unless all such affected Holders agree, in writing, to waive such default; or

          (4) the rescission of which would conflict with any judgment or decree of a court of competent jurisdiction.

          Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right arising therefrom.

Section 6.5 CONTROL BY MAJORITY

          Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture, that the Trustee determines in good faith may be unduly prejudicial to the rights of other Holders of Notes not joining in the giving of such direction or that may involve the Trustee in personal liability and

59

the Trustee may take any other action it deems proper that is not inconsistent with any such direction received from Holders of the Notes.

Section 6.6 LIMITATION ON SUITS

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

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

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

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

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

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

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

Section 6.7 RIGHTS OF HOLDERS OF NOTES TO RECEIVE PAYMENT

          Notwithstanding any other provision of this Indenture and subject to Article XI, except as permitted by Section 9.2 hereof, the right of any Holder of a Note to receive payment of the principal of, premium and Liquidated Damages, if any, and interest on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase) or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder.

Section 6.8 COLLECTION SUIT BY TRUSTEE

          If an Event of Default specified in Section 6.1 hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of principal of, premium and Liquidated Damages, if any, and interest remaining unpaid on the Notes and interest on overdue principal and, to the extent lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

Section 6.9 TRUSTEE MAY FILE PROOFS OF CLAIM

          The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative

60

to the Company (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.7 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.7 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding; provided, however that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and may be a member of the creditor’s committee.

Section 6.10 PRIORITIES

          If the Trustee collects any money pursuant to this Article, it shall pay out the money in the following order:

          First: to the Trustee, its agents and attorneys for amounts due under Section 7.7 hereof, including payment of all compensation, expense and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection (including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel);

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

          Third: without duplication, to the Holders for any other Obligations owing to the Holders under the Notes or this Indenture; and

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

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

Section 6.11 UNDERTAKING FOR COSTS

          In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in the suit, having due regard to the merits and good

61

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 of a Note pursuant to Section 6.7 hereof, or a suit by Holders of more than 10% in principal amount of the then outstanding Notes.

ARTICLE VII
TRUSTEE

Section 7.1 DUTIES OF TRUSTEE

          (a) If an Event of Default of which the Trustee has knowledge has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in its exercise, as a prudent man would exercise or use under the circumstances in the conduct of its own affairs.

          (h) The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other

Section 7.3 INDIVIDUAL RIGHTS OF TRUSTEE

          The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest (as defined in the TIA) it must eliminate such conflict within 90 days, apply to the SEC for permission to continue as trustee or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof.

Section 7.4 TRUSTEE’S DISCLAIMER

          The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes, it shall not be accountable for the Company’s use of the proceeds from the Notes or any money paid to the Company or upon the Company’s direction under any provision of this Indenture, it shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it shall not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication.

Section 7.5 NOTICE OF DEFAULTS

          If a Default or Event of Default occurs and is continuing and if it is known to the Trustee, the Trustee shall mail to Holders of Notes a notice in the manner and to the extent provided by Section 313(c) of the TIA of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, premium, if any, Liquidated Damages, if any, or interest on any Note, the Trustee may withhold the notice if and so long as a committee of its Officers in good faith determines that withholding the notice is in the interests of the Holders of the Notes.

Section 7.6 REPORTS BY TRUSTEE TO HOLDERS OF THE NOTES

          Within 60 days after each May 15 beginning with the May 15 following the date of this Indenture, and for so long as Notes remain outstanding, the Trustee shall mail to the Holders of the Notes a brief report dated as of such reporting date that complies with TIA § 313(a) (but if no event described in TIA § 313(a) has occurred within the 12 months preceding the reporting date, no report need be transmitted). The Trustee also shall comply with TIA § 313(b)(2). The Trustee shall also transmit by mail all reports as required by TIA § 313(c).

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

The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder, except to the extent the Company has been prejudiced thereby. The Company shall defend the claim and the Trustee shall cooperate in the defense. In the event of a conflict of interest between the Company and the Trustee, the Trustee may have separate counsel and the Company shall pay the reasonable fees and expenses of such counsel. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld.

          The obligations of the Company under this Section 7.7 shall survive the satisfaction and discharge of this Indenture.

          To secure the Company’s payment obligations in this Section 7.7, the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on particular Notes. Such Lien shall survive the satisfaction and discharge of this Indenture.

          When the Trustee incurs expenses or renders services after an Event of Default specified in Sections 6.1(i) or 6.1(j) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law.

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

          A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders of the Notes. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee; provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.7 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.8, the Company’s obligations under Section 7.7 hereof shall continue for the benefit of the retiring Trustee.

Section 7.9 SUCCESSOR TRUSTEE BY MERGER, ETC.

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

          Upon the Company’s exercise under Section 8.1 hereof of the option applicable to this Section 8.3, subject to the satisfaction of the applicable conditions set forth in Section 8.4 hereof, the Company and the Guarantors shall be released from their respective obligations under Sections 4.3, 4.4, 4.5, 4.7, 4.8, 4.9, 4.10, 4.11, 4.12, 4.13, 4.14, 4.15, 4.16, 4.17, 5.1(3) and 5.1(4)

67

hereof and Article X hereof on and after the date the conditions set forth below are satisfied (hereinafter, “Covenant Defeasance”), and the Notes and the Guarantees 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 Company 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 a Default or an Event of Default under Section 6.1 hereof, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon the Company’s exercise under Section 8.1 hereof of the option applicable to this Section 8.3, subject to the satisfaction of the applicable conditions set forth in Section 8.4 hereof, (x) Sections 6.1(c) through 6.1(h) hereof and Section 6.1(k) hereof shall not constitute Events of Default to the extent such events occur thereafter and (y) Sections 6.1(i) and 6.1(j) hereof shall not constitute an Event of Default to the extent they occur after the 91st day following the occurrence of the Company’s exercise of Covenant Defeasance; provided, however that for all other purposes as set forth herein, such Covenant Defeasance provisions shall be effective.

Section 8.4 CONDITIONS TO LEGAL OR COVENANT DEFEASANCE

          In order to exercise either Legal Defeasance or Covenant Defeasance:

          (a) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, United States legal tender, U.S. Government Obligations, or a combination thereof, in amounts that will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, premium, if any, and Liquidated Damages, if any, and interest on the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be, and the Trustee must have, for the benefit of Holders of the Notes, a valid, perfected exclusive security interest in such trust;

          (b) in the case of an election under Section 8.2 hereof, the Company must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee from United States legal counsel confirming that (A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (B) since the date of this Indenture, there has been a change in the applicable federal income tax law, in either case to the effect that, the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

          (c) in the case of an election under Section 8.3 hereof, the Company must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee from United States legal counsel confirming that Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be

68

          (d) in the case of an election under Section 8.2 or 8.3 hereof, (x) no Default or Event of Default shall have occurred and be continuing on the date of the deposit, and (y) no Event of Default specified in Section 6.1(i) or (j) hereof shall have occurred at any time from the date of the deposit to the 91st calendar day thereafter (it being understood that this condition to Legal Defeasance or Covenant Defeasance may not be satisfied until such 91st calendar day after the date of deposit);

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

          (f) the Company must deliver to the Trustee an Officers’ Certificate stating that the deposit was not made by the Company with the intent to hinder, delay or defraud any other of the Company’s creditors;

          (g) the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that after the 91st day following the deposit, the trust funds (except as to trust funds that would be payable to holders of Notes who are “Insiders” as that term is defined by the Bankruptcy Code) will not be subject to Section 547 of the Bankruptcy Code; and

          (h) the Company must deliver to the Trustee an Officers’ Certificate confirming the satisfaction of the conditions in clauses (a) through (g) above, and an Opinion of Counsel, confirming the satisfaction of the conditions in clauses (a) (with respect to the validity and perfection of the security interest), (b), (c) and (e).

          Legal Defeasance and Covenant Defeasance shall be deemed to occur on the date all of the applicable conditions set forth in this Section 8.4 are satisfied.

Section 8.5 DEPOSITED MONEY AND GOVERNMENT SECURITIES TO BE HELD IN TRUST; OTHER MISCELLANEOUS
                   PROVISIONS

          Subject to Section 8.6 hereof, all money and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.5, the “Trustee”) pursuant to Section 8.4 hereof in respect of the outstanding Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest (and Liquidated Damages, if any), but such money need not be segregated from other funds except to the extent required by law.

          The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or U.S. Government Obligations deposited pursuant to Section 8.4 hereof or the principal and interest received in respect thereof, other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes.

69

          Anything in this Article VIII to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon the request of the Company any money or U.S. Government Obligations held by it as provided in Section 8.4 hereof which, in the opinion of a firm of independent public accountants nationally recognized in the United States expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.4(a) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

Section 8.6 REPAYMENT TO COMPANY

          Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium, if any, Liquidated Damages, if any, or interest on any Note and remaining unclaimed for two years after such principal, and premium, if any, Liquidated Damages, if any, or interest has become due and payable shall be paid to the Company on its written request or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter, as a creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in the New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining will be repaid to the Company.

Section 8.7 REINSTATEMENT

          If the Trustee or Paying Agent is unable to apply any United States legal tender or U.S. Government Obligations in accordance with Section 8.2 or 8.3 hereof, as the case may be, by reason of any order directing the repayment of the deposited money to the Company or otherwise making the deposit unavailable to make payments under the Notes when due, or if any court enters an order avoiding the deposit of money with the Trustee or Paying Agent or otherwise requires the payment of the money so deposited to the Company or to a fund for the benefit of its creditors, then (so long as the insufficiency exists or the order remains in effect) the Company’s and the Guarantors’ obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.2 or 8.3 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.2 or 8.3 hereof, as the case may be; provided, however, that, if the Company makes any payment of principal of, premium, if any, Liquidated Damages, if any, or interest on any Note following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent.

Section 8.8 SATISFACTION AND DISCHARGE

          This Indenture will be discharged and will cease to be of further effect (except as to surviving rights of registration of transfer of the Notes) as to all outstanding Notes when either:

          (a) all the Notes previously authenticated and delivered (except lost, stolen or destroyed Notes which have been replaced and Notes for whose payment money has theretofore been deposited with the Trustee or the paying agent in trust or segregated and held in

70

trust by the Company and thereafter repaid to the Company or a Guarantor) have been delivered to the Trustee for cancellation; or

          (b) (i) all Notes have been called for redemption pursuant Section 3.7 by mailing to holders a notice of redemption or all Notes otherwise have become due and payable;;

               (ii) the Company has irrevocably deposited or caused to be irrevocably deposited with the Trustee funds in an amount sufficient to pay and discharge the entire Indebtedness on the Notes not theretofore delivered to the Trustee for cancellation, for principal of, and interest and Liquidated Damages, if any, on the Notes to the date of redemption or maturity, as the case may be, together with irrevocable instructions from the Company directing the Trustee to apply such funds to the payment thereof at maturity or redemption, as the case may be;

               (iii) each of the Company and the Guarantors has paid all other sums payable by it under the Indenture, the Notes and the Guarantees;

               (iv) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit);

               (v) such deposit shall not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than the Indenture) to which the Company or any of the Guarantors is a party or by which the Company or any of the Guarantors is bound; and

               (vi) the Company shall have delivered to the Trustee an Officers Certificate and an Opinion of Counsel confirming the satisfaction of all conditions set forth in clauses (i) through (v) above.

ARTICLE IX
AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.1 WITHOUT CONSENT OF HOLDERS OF NOTES

          Notwithstanding Section 9.2 hereof, the Company, the Guarantors and the Trustee may amend or supplement this Indenture, the Notes or any Guarantee, in each case without the consent of any Holder of a Note:

          (a) to cure any ambiguity, defect or inconsistency;

          (b) to provide for uncertificated Notes in addition to or in place of certificated Notes or to alter the provisions of Article II hereof in a manner that does not adversely affect any Holder;

          (c) to provide for the assumption of the Company’s obligations to the Holders of the Notes in the case of a merger or consolidation pursuant to Article V hereof;

          (d) to provide for additional Guarantors as set forth in Section 4.15 hereof or for the release or assumption of a Guarantee in compliance with this Indenture;

71

          (e) to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the rights hereunder of any Holder of the Notes;

          (f) to comply with the provisions of the Depositary, Euroclear or Clearstream or the Trustee with respect to the provisions of this Indenture or the Notes relating to transfers and exchanges of Notes or beneficial interests therein;

          (g) to comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA;

          (h) to evidence and provide for the acceptance of appointment hereunder by a successor Trustee with respect to the Notes; or

          (i) to provide for the issuance of Additional Notes in accordance with the limitations set forth in this Indenture as of the date hereof..

          Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental Indenture, Notes or Guarantees, and upon receipt by the Trustee of the documents described in Section 9.6 hereof, the Trustee shall join with the Company in the execution of any amended or supplemental Indenture, Notes or Guarantees authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to enter into such agreements that adversely affects its own rights, duties or immunities under this Indenture or otherwise.

Section 9.2 WITH CONSENT OF HOLDERS OF NOTES

          Except as expressly stated otherwise in this Section 9.2, and subject to Sections 6.4 and 6.7 hereof, the Company, the Guarantors and the Trustee may amend or supplement this Indenture, the Notes and the Guarantees, with the consent of the Holders of a majority in aggregate principal amount of the Notes then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Notes), and, subject to Sections 6.4 and 6.7 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium, if any, or interest on the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture, the Notes or the Guarantees may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Notes).

          The Company, the Guarantors and the Trustee may not amend or waive any provision of this Indenture or the Notes, without the consent of each Holder adversely affected thereby, to:

          (a) (i) change the Stated Maturity on any Note, or reduce the principal amount thereof or the rate (or extend the time for payment) of interest thereon or any premium payable upon the redemption thereof at the option of the Company, or change the city of payment where, or the coin or currency in which, any Note or any premium or the interest thereon is payable, or impair the right to institute suit for the enforcement of any such payment on or after the Stated Maturity thereof (or, in the case of redemption at the option of the Company, on or

72

after the Redemption Date), or (ii) reduce the Change of Control Purchase Price or the Asset Sale Offer Price after the corresponding Asset Sale or Change of Control has occurred or (iii) alter the provisions regarding the Company’s right to redeem the Notes, in a manner adverse to the Holders; or

          (b) reduce the percentage in principal amount of the outstanding Notes, the consent of whose Holders is required for any such amendment, supplemental indenture or waiver provided for in this Indenture; or

          (c) modify any of the waiver provisions, except to increase any required percentage or to provide that certain other provisions of this Indenture cannot be modified or waived without the consent of the Holder of each outstanding Note affected thereby; or

          (d) cause the Notes or any Guarantee to become contractually subordinate in right of payment to any other Indebtedness.

          Except as expressly stated otherwise in paragraph (a)(ii) above, Sections 4.12 and 4.14 hereof may be amended, waived or modified in accordance with the first paragraph of this Section 9.2, without the consent of each Holder affected.

          In connection with any amendment, supplement or waiver under this Article IX, the Company may, but shall not be obligated to, offer to any Holder who consents to such amendment, supplement or waiver, or to all Holders, consideration for such Holder’s consent to such amendment, supplement or waiver.

          Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental Indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 9.6 hereof, the Trustee shall join with the Company in the execution of such amended or supplemental Indenture unless such amended or supplemental Indenture adversely affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental Indenture.

          It shall not be necessary for the consent of the Holders of Notes under this Section 9.2 to approve the particular form of any proposed amendment or waiver, but it shall be sufficient if such consent approves the substance thereof.

          After an amendment, supplement or waiver under this Section 9.2 becomes effective, the Company shall mail to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amended or supplemental Indenture or waiver.

Section 9.3 COMPLIANCE WITH TRUST INDENTURE ACT

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

73

Section 9.4 REVOCATION AND EFFECT OF CONSENTS

          Until an amendment, supplement or waiver becomes effective (as determined by the Company and which may be prior to any such amendment, supplement or waiver becoming operative), a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same Indebtedness as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective (as determined by the Company and which may be prior to any such amendment, supplement or waiver becoming operative).

          The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver, which record date shall be the date so fixed by the Company notwithstanding the provisions of the TIA. If a record date is fixed, then notwithstanding the last sentence of the immediately preceding paragraph, those Persons who were Holders at such record date, and only those Persons (or their duly designated proxies), shall be entitled to revoke any consent previously given, whether or not such Persons continue to be Holders after such record date.

          After an amendment, supplement or waiver becomes effective, it shall bind every Holder unless it makes a change described in any of clauses (a) through (e) of Section 9.2 hereof, in which case, the amendment, supplement or waiver shall bind only each Holder of a Note who has consented to it and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note; provided, that any such waiver shall not impair or affect the right of any Holder to receive payment of principal and premium of and interest (and Liquidated Damages, if any) on a Note, on or after the respective dates set for such amounts to become due and payable expressed in such Note, or to bring suit for the enforcement of any such payment on or after such respective dates.

Section 9.5 NOTATION ON OR EXCHANGE OF NOTES

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

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

Section 9.6 TRUSTEE TO SIGN AMENDMENTS, ETC.

          The Trustee shall sign any amended or supplemental Indenture authorized pursuant to this Article IX if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Company may not sign an amended or supplemental Indenture until the Board of Directors approves it. In executing any amended or supplemental Indenture, the Trustee shall be entitled to receive indemnity reasonably satisfactory to it and to receive and (subject to Section 7.1 hereof) shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental Indenture is authorized or permitted by this Indenture.

74

ARTICLE X
GUARANTY

Section 10.1 GUARANTEES

          By its execution hereof, each of the Guarantors acknowledges and agrees that it receives substantial benefits from the Company and that such party is providing its Guarantee for good and valuable consideration, including, without limitation, such substantial benefits and services. Accordingly, subject to the provisions of this Article X, each Guarantor, jointly and severally, hereby unconditionally guarantees on a senior subordinated basis to each Holder of a Note authenticated and delivered by the Trustee and its successors and assigns that: (i) the principal of, premium, if any, and interest and Liquidated Damages, if any, on the Notes shall be duly and punctually paid in full when due, whether at maturity, by acceleration, call for redemption, upon a Change of Control Offer, an Asset Sale Offer, or otherwise, and interest on overdue principal, premium, if any, Liquidated Damages, if any, and (to the extent permitted by law) interest on any interest, if any, on the Notes and all other obligations of the Company to the Holders or the Trustee under the Notes, this Indenture and the Registration Rights Agreement (including fees, expenses or other) shall be promptly paid in full or performed, all in accordance with the terms hereof; and (ii) in case of any extension of time of payment or renewal of any Notes or any of such other obligations under the Notes or the Registration Rights Agreement, the same shall be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration, call for redemption, upon a Change of Control, an Asset Sale Offer, or otherwise, subject, however, in the case of clauses (i) and (ii) above, to the limitations set forth in Section 10.5 hereof (collectively, the “Guarantee Obligations”).

          Subject to the provisions of this Article X, each Guarantor hereby agrees that its Guarantee hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes, this Indenture, the Registration Rights Agreement or the absence of any action to enforce the same, the entry of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor. Each Guarantor hereby waives and relinquishes (to the extent it may lawfully do so): (a) any right to require the Trustee, the Holders or the Company (each, a “Benefitted Party”) to proceed against the Company, the Subsidiaries or any other Person or to proceed against or exhaust any security held by a Benefitted Party at any time or to pursue any other remedy in any secured party’s power before proceeding against the Guarantors; (b) any defense that may arise by reason of the incapacity, lack of authority, death or disability of any other Person or Persons or the failure of a Benefitted Party to file or enforce a claim against the estate (in administration, bankruptcy or any other proceeding) of any other Person or Persons; (c) demand, protest and notice of any kind (except as expressly required by this Indenture), including but not limited to notice of the existence, creation or incurring of any new or additional Indebtedness or obligation or of any action or non-action on the part of the Guarantors, the Company, the Subsidiaries, any Benefitted Party, any creditor of the Guarantors, the Company or the Subsidiaries or on the part of any other Person whomsoever in connection with any obligations the performance of which are hereby guaranteed; (d) any defense based upon an election of remedies by a Benefitted Party, including but not limited to an election to proceed against the Guarantors for reimbursement; (e) any defense based upon any statute or rule of law which provides that the obligation of a surety must be neither larger in amount nor in other respects more burdensome than that of the principal; (f) any defense arising because of a Benefitted Party’s election, in any proceeding instituted under the Bankruptcy Law, of the application of Section 1111(b)(2) of the Bankruptcy Code; and (g) any defense based on any

75

borrowing or grant of a security interest under Section 364 of the Bankruptcy Code. The Guarantors hereby covenant that, except as otherwise provided therein, the Guarantees shall not be discharged except by payment in full of all Guarantee Obligations, including the principal, premium, if any, and interest on the Notes and all other costs provided for under this Indenture or as provided in Article VIII.

          If any Holder or the Trustee is required by any court or otherwise to return to either the Company or the Guarantors, or any trustee or similar official acting in relation to either the Company or the Guarantors, any amount paid by the Company or the Guarantors to the Trustee or such Holder, the Guarantees, to the extent theretofore discharged, shall be reinstated in full force and effect. Each of the Guarantors agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any Guarantee Obligations hereby until payment in full of all such obligations guaranteed hereby. Each Guarantor agrees that, as between it, on the one hand, and the Holders of Notes and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article VI hereof for the purposes hereof, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guarantee Obligations, and (y) in the event of any acceleration of such obligations as provided in Article VI hereof, such Guarantee Obligations (whether or not due and payable) shall forthwith become due and payable by such Guarantor for the purpose of the Guarantee.

Section 10.2 EXECUTION AND DELIVERY OF GUARANTEES

          To evidence the Guarantees set forth in Section 10.1 hereof, each of the Guarantors agrees that a notation of the Guarantees substantially in the form included in Exhibit A hereto shall be endorsed on each Note authenticated and delivered by the Trustee and that this Indenture shall be executed on behalf of each of the Guarantors by an Officer of each of the Guarantors.

          Each of the Guarantors agree that the Guarantees set forth in this Article X shall remain in full force and effect and apply to all the Notes notwithstanding any failure to endorse on each Note a notation of the Guarantees.

          If an Officer whose facsimile signature is on a Note or a notation of Guarantee no longer holds that office at the time the Trustee authenticates the Note on which the Guarantees are endorsed, the Guarantees shall be valid nevertheless.

          The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Guarantees set forth in this Indenture on behalf of the Guarantors.

Section 10.3 GUARANTORS MAY CONSOLIDATE, ETC., ON CERTAIN TERMS

          (a) Nothing contained in this Indenture or in the Notes shall prevent any consolidation or merger of any Guarantor with or into each other or with or into the Company. Upon any such consolidation or merger, the Guarantee of the Guarantor that does not survive the consolidation or merger shall no longer be of any force or effect.

          (b) Except for a merger or consolidation in which a Guarantor is sold and its Guarantee is released in compliance with the provisions of Section 10.4 hereof, no Guarantor shall consolidate or merge with or into (whether or not such Guarantor is the surviving Person)

76

another Person unless, subject to the provisions of the last sentence if this Section 10.3(b) and the other provisions of this Indenture, (i) the Person formed by or surviving any such consolidation or merger (if other than such Guarantor) assumes all the obligations of such Guarantor pursuant to a supplemental indenture in form reasonably satisfactory to the Trustee, pursuant to which such Person shall guarantee, on a senior basis, all of such Guarantor’s obligations under such Guarantor’s Guarantee on the terms set forth in this Indenture, and deliver to the Trustee an Opinion of Counsel that such guaranty has been duly authorized, executed and delivered; and (ii) immediately before and immediately after giving effect to such transaction on a pro forma basis, no Default or Event of Default shall have occurred or be continuing. In case of any such consolidation or merger and upon the assumption by the successor corporation, by supplemental indenture, executed and delivered to the Trustee and reasonably satisfactory in form to the Trustee, of the Guarantees endorsed upon the Notes and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by such Guarantor, such successor corporation shall succeed to and be substituted for such Guarantor with the same effect as if it had been named herein as a Guarantor. Such successor corporation thereupon may cause to be signed any or all of the Guarantees to be endorsed upon all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee. All the Guarantees so issued shall in all respects have the same legal rank and benefit under this Indenture as the Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all of such Guarantees had been issued at the date of the execution hereof. The provisions of this Section 10.3(b) shall not apply to the merger of any Guarantors with and into each other or with or into the Company.

          (c) The Trustee, subject to the provisions of Section 11.4 hereof, shall be entitled to receive an Officers’ Certificate as conclusive evidence that any such consolidation or merger, and any such assumption of Guarantee Obligations, comply with the provisions of this Section 10.3. Such Officers’ Certificate shall comply with the provisions of Section 11.5 hereof.

Section 10.4 RELEASE OF GUARANTORS

          Notwithstanding Section 10.3(b) hereof, upon the sale or disposition (including by merger or stock purchase) of a Guarantor (as an entirety) to an entity which is not and is not required to become a Guarantor, the designation of a Subsidiary as an Unrestricted Subsidiary, or the liquidation or dissolution of a Guarantor, which transaction is otherwise in compliance with this Indenture (including, without limitation, Section 4.12), such Guarantor will be deemed released from its Obligations under its Guarantee of the Notes; provided, however, that any such termination shall occur only to the extent that all obligations of such Guarantor under all of its guarantees of any of the Company’s Indebtedness of any other of its Subsidiaries shall also terminate upon such release, sale or transfer and none of its Equity Interests are pledged for the benefit of any holder of any of the Company’s Indebtedness or any Indebtedness of any of its Subsidiaries.

          Upon delivery by the Company to the Trustee of an Officer’s Certificate, to the effect that such sale or other disposition or that such designation or that such liquidation or dissolution was made by the Company in accordance with the provisions of this Indenture, the Trustee shall execute any documents reasonably required in order to evidence the release of any such Guarantor from its obligations under its Guarantee and any Liens in favor of the Notes.

          6.   Mandatory Redemption. The Company shall not be required to make mandatory redemption payments with respect to the Notes. The Notes shall not have the benefit of any sinking fund.

          7.   Offers to Purchase.

               (a)   Change of Control. In the event that a Change of Control has occurred, each Holder of Notes will have the right, at such Holder’s option, pursuant to an offer (subject only to conditions required by applicable law, if any) by the Company (the “Change of Control Offer”), to require the Company to repurchase all or any part of such Holder’s Notes (provided, that the principal amount of such Notes must be $1,000 or an integral multiple thereof) at a cash price equal to 101% of the principal amount (the “Change of Control Purchase Price”), together with accrued and unpaid interest and Liquidated Damages, if any, thereon to the Change of Control Purchase Date.

               The Change of Control Offer shall be made within 30 Business Days following a Change of Control and shall remain open for at least 20 Business Days and not more than 30 Business Days following its commencement (the “Change of Control Offer Period”). Upon expiration of the Change of Control Offer Period, the Company promptly shall purchase all Notes properly tendered in response to the Change of Control Offer.

               On or before the Change of Control Purchase Date, the Company shall: (i) accept for payment Notes or portions thereof properly tendered pursuant to the Change of Control Offer; (ii) deposit with the Paying Agent cash sufficient to pay the Change of Control Purchase Price (together with accrued and unpaid interest and Liquidated Damages, if any) of all Notes so tendered; and (iii) deliver to the Trustee the Notes so accepted together with an Officers’

A-5

Certificate listing the Notes or portions thereof being purchased by the Company. The Paying Agent promptly will pay the Holders of Notes so accepted an amount equal to the Change of Control Purchase Price (together with accrued and unpaid interest and Liquidated Damages, if any) and the Trustee promptly will authenticate and deliver to such Holders a new Note equal in principal amount to any unpurchased portion of the Note surrendered. Any Notes not so purchased will be delivered promptly by the Company to the Holder thereof. The Company publicly will announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Purchase Date.

               If the Change of Control Purchase Date is on or after an Interest Record Date and on or before the associated Interest Payment Date, any accrued and unpaid interest (and Liquidated Damages, if any) due on such Interest Payment Date will be paid to the Person in whose name a Note is registered at the close of business on such Interest Record Date.

               The Company shall not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control made by the Company and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer.

               (b)   Asset Sale. Subject to certain exceptions set forth in the Indenture, the Company shall not, and shall not permit any of the Company’s Subsidiaries to, in one or a series of related transactions, convey, sell, transfer, assign or otherwise dispose of, directly or indirectly, any of their property, business or assets, including by merger or consolidation (in the case of a Subsidiary of the Company), and including any sale or other transfer or issuance (but not an issuance in the case of an Unrestricted Subsidiary) of any Equity Interests of any of the Company’s Subsidiaries or Unrestricted Subsidiaries, whether by the Company or one of its Subsidiaries and including any sale-leaseback transaction (any of the foregoing, an “Asset Sale”), unless, with respect to any Asset Sale or related series of Asset Sales involving securities, property or assets with an aggregate fair market value in excess of $5,000,000 (an Asset Sale (including a series of related Asset Sales) of less than $5,000,000 shall not be subject to this clause (b)), (a) at least 75% (or 50%, in the case of the sale of the Transportation Management System business of the Company) of the total consideration for such Asset Sale or series of related Asset Sales consists of cash or Cash Equivalents, and (b) the Company’s Board of Directors determines in good faith that the Company will be receiving or such Subsidiary will be receiving, as applicable, fair market value for such Asset Sale. Solely for purposes of the preceding sentence, “cash and Cash Equivalents” shall include (i) any of the Company’s or the Company’s Subsidiaries liabilities (as shown on the Company’s or the Company’s Subsidiaries’ most recent balance sheet) other than (x) Indebtedness under the Company’s Credit Agreement, (y) contingent liabilities and (z) liabilities that are by their terms subordinated to the Notes or any Guarantee assumed by the purchaser; provided, that, in each case, the Company and its Subsidiaries are fully released from obligations in connection therewith, (ii) assets for use in a Related Business or Equity Interests of a Person that becomes a Subsidiary which is primarily engaged in a Related Business, (iii) Indebtedness incurred under the Credit Agreement that is assumed by a transferee; provided that the Company and its Subsidiaries are fully released from obligations in connection with the amounts assumed and the assumed Indebtedness permanently reduced the Indebtedness under the Credit Agreement (and in the case of a revolver or similar arrangement that makes credit available, such commitment is permanently reduced by such amount); provided further, that if Indebtedness under the Credit Agreement in the form of letters of credit are assumed by the purchaser in connection with the sale of the Transportation Management Systems business of the Company, and the Company and the Company’s

A-6

Subsidiaries are fully released from obligations in connection with such letters of credit, then the Credit Agreement need not be permanently reduced by the amount of such assumed letters of credit, and, (iv) property that within 30 days of such Asset Sale is converted into cash or Cash Equivalents; provided, that such cash and Cash Equivalents shall be treated as Net Cash Proceeds attributable to the original Asset Sale for which such property was received.

               Within 365 days following such Asset Sale, Net Cash Proceeds therefrom (the “Asset Sale Amount”) shall be: (a) used (i) to retire Purchase Money Indebtedness secured by the asset which was the subject of the Asset Sale; or (ii) to retire and permanently reduce Indebtedness incurred under the Credit Agreement; provided, that in the case of a revolver or similar arrangement that makes credit available, such commitment is permanently reduced by such amount; or (b) used to make (i) capital expenditures or (ii) investments in assets and property (other than notes, bonds, obligations and securities, except in connection with the acquisition of a Person in a Related Business that becomes a Subsidiary that, if required under the Indenture, becomes a Guarantor) which in the good faith reasonable judgment of the Company’s Board of Directors will immediately constitute or be a part of, or useful in a Related Business of the Company or such Subsidiary (if it continues to be a Subsidiary) immediately following such transaction; or the Company shall, within such 365-day period, enter into a legally binding agreement to apply such Net Cash Proceeds as described in this clause (b) within six months after such agreement is entered into and apply such Net Cash Proceeds in accordance with the provisions of this clause (b); provided, that if such agreement terminates, the Company shall have until the later of (i) 90 days after the date of such termination and (ii) 365 days after the date of the Asset Sale resulting in such Net Cash Proceeds to effect such application.

               The accumulated Net Cash Proceeds from Asset Sales and from any Event of Loss not applied as set forth in the preceding paragraph shall constitute “Excess Proceeds.” Pending the final application of any Net Cash Proceeds, the Company may temporarily reduce revolving credit borrowings or otherwise invest or use for general corporate purposes (other than Restricted Payments that are not solely Restricted Investments) the Net Cash Proceeds in any manner that is not prohibited by the Indenture. When the Excess Proceeds equal or exceed $15,000,000, within 20 Business Days the Company shall offer to repurchase the Notes, together with any other Indebtedness ranking on a parity with the Notes and with similar provisions requiring the Company to make an offer to purchase such Indebtedness with the proceeds from such Asset Sale pursuant to a cash offer (subject only to conditions required by applicable law, if any), pro rata in proportion to the respective principal amounts of such Indebtedness (or accreted values in the case of Indebtedness issued with an original issue discount) and the Notes (the “Asset Sale Offer”) at a purchase price of 100% of the principal amount (or accreted value in the case of Indebtedness issued with an original issue discount) (the “Asset Sale Offer Price”) together with accrued and unpaid interest and Liquidated Damages, if any, to the date of payment. The Asset Sale Offer shall remain open for at least 20 Business Days following its commencement (the “Asset Sale Offer Period”). Upon expiration of the Asset Sale Offer Period, the Company shall apply an amount equal to the Excess Proceeds (the “Asset Sale Offer Amount”) plus an amount equal to accrued and unpaid interest and Liquidated Damages, if any, to the purchase of all Indebtedness properly tendered in accordance with the provisions hereof (on a pro rata basis if the Asset Sale Offer Amount is insufficient to purchase all Indebtedness so tendered) at the Asset Sale Offer Price (together with accrued and unpaid interest and Liquidated Damages, if any, to the date of payment). To the extent that the aggregate amount of Notes and such other pari passu Indebtedness tendered pursuant to an Asset Sale Offer is less than the Asset Sale Offer Amount, the Company may use any remaining Net Cash Proceeds as otherwise permitted by the Indenture. Following the consummation of each Asset Sale Offer, the Excess Proceeds amount shall be reset to zero.

A-7

          8.      Denominations, Transfer, Exchange. The Notes are in registered form without coupons in denominations of $1,000 and integral multiples of $1,000.

               If a Default occurs and is continuing, the Trustee must, within 90 days after the occurrence of such Default, give to the Holders notice of such Default, but the Trustee shall be protected in withholding such notice if it in good faith determines that the withholding of such notice is in the interest of the Holders, except in the case of a Default in the payment of the principal of, premium, if any, or interest on any of the Notes when due or in the payment of any redemption or repurchase obligation.

          12.   Trustee Dealings with Company. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not the Trustee.

Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.

          14.   Authentication. This Note shall not be valid until authenticated by the manual signature of the Trustee or an authenticating agent.
