If the principal amount of any Note is considered paid under Section 4.01 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, by 10:00 a.m. Eastern Time on a redemption date or other maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes will be deemed to be no longer outstanding and will cease to accrue interest.

Section 2.09 Treasury Notes.

Upon the request of the Trustee, the Company and any Notes Guarantor shall provide an Officer’s Certificate to the Trustee that details the amount, if any, of Notes owned by the Company or any Notes Guarantor, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any Notes Guarantor.

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, will authenticate temporary Notes. temporary Notes will be substantially in the form of certificated Notes but may have variations that the Company considers appropriate for temporary Notes and as may be reasonably acceptable to the Trustee. Without unreasonable delay, the Company will prepare and the Trustee will authenticate definitive Notes in exchange for temporary Notes.

Holders of temporary Notes will 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 will forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee (and no one else) will cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and will dispose of canceled Notes (subject to the record retention requirement of the Exchange

74

Act and any internal record retention policies of the Trustee) in accordance with its customary procedures. Certification of the disposal of all canceled Notes will be delivered to the Company upon written request. 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.

If the Company defaults in a payment of interest on the Notes, it will pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01 hereof. The Quotation Agent shall calculate the amount of defaulted interest and the Company will notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Company will fix or cause to be fixed each such special record date and payment date; provided that no such special record date may be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Company (or, upon the written request of the Company, the Trustee in the name and at the expense of the Company) will send to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid. The Trustee shall not at any time be under any duty or responsibility to any Holder to determine defaulted interest, or with respect to the nature, extent, or calculation of the amount of defaulted interest owed, or with respect to the method employed in such calculation of defaulted interest.

Section 2.13 CUSIP Numbers.

The Company will promptly notify the Trustee in writing of any change in the “CUSIP” numbers. The Company in issuing the Notes may use CUSIP or ISIN numbers, as applicable, (if then generally in use) and, if so, the Trustee shall use CUSIP or ISIN numbers, as applicable, 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 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.

If the holders of more than 50.0% of the principal amount of the Notes then outstanding accept such offer, the Company shall promptly notify the remaining holders of such fact and the expiration date for the acceptance by holders of Notes of such offer shall be extended by the number of days necessary to give each such remaining holder at least three (3) Business Days from its receipt of such notice to accept such offer. The Company will promptly cancel all Notes acquired by it or any Affiliate pursuant to any payment, prepayment or purchase of Notes pursuant to this Indenture and no Notes may be issued in substitution or exchange for any such Notes.

(8) that no representation is made as to the correctness or accuracy of the CUSIP number listed in such notice or printed on the Notes; and

(9) any conditions precedent to such redemption, and if such redemption is subject to satisfaction of one or more conditions precedent, such notice may state that, at the Company discretion, the redemption date may be delayed on one or more occasions either to a date specified in a subsequent notice to holders of the Notes or until such time (which date or time may be more than 60 days after the date the notice of redemption was mailed or otherwise sent) as any or all such conditions shall be satisfied or waived, and that such redemption will not occur and such notice will be rescinded if any or all such conditions shall not have been satisfied as and when required (as determined by the Company in its sole discretion taking into account any election by the Company to delay such redemption date), unless the Company has waived any such conditions that are not satisfied, or at any time if in the good faith judgment of the Company any or all of such conditions will not be satisfied.

77

At the Company’s request, the Trustee will give the notice of redemption in the Company’s name and at the Company’s expense if the Officer’s Certificate delivered to the Trustee pursuant to Section 3.01 hereof directs and authorizes the Trustee to give such notice of redemption and sets forth the information to be stated in such notice of redemption as provided in the preceding paragraph.

If an optional redemption of the Notes is subject to satisfaction of one or more conditions precedent (other than with respect to a redemption pursuant to Section 3.07(b)), such notice may state that, at the Company’s discretion, the redemption date may be delayed on one or more occasions either to a date specified in a subsequent notice to Holders of the Notes or until such time (which date or time may be more than 60 days after the date the notice of redemption was mailed or otherwise sent) as any or all such conditions shall be satisfied or waived, and that such redemption will not occur and such notice will be rescinded if any or all such conditions shall not have been satisfied as and when required (as determined by the Company in its sole discretion taking into account any election by the Company to delay such redemption date), unless the Company has waived any such conditions that are not satisfied, or at any time if in the good faith judgment of the Company any or all of such conditions will not be satisfied. The Company will provide the Trustee with written notice of the satisfaction or waiver of such conditions precedent, the delay of such redemption or the rescission of such notice of redemption prior to the close of business on the Business Day prior to the redemption date in the same manner that the related notice of redemption was given to the Trustee, and the Trustee will send a copy of such notice to the Trustee to the Holders in the same manner that the related notice of redemption was given to such Holders.

Section 3.05 Deposit of Redemption or Purchase Price.

(a) No later than 10:00 a.m. Eastern Time on the redemption or purchase date, the Company will deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase price of, and accrued and unpaid interest on, all Notes to be redeemed or purchased on that date.

If a Note is redeemed or purchased on or after an interest Record Date but on or prior to the related Interest Payment Date, then any accrued and unpaid interest shall be paid to the Person in whose name such Note was registered at the close of business on such Record Date. If any Note called for redemption or tendered for purchase is not so paid upon surrender for redemption or purchase because of the failure of the Company to comply with Section 3.05(a), interest shall be paid on the unpaid principal, from the redemption or purchase 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 4.01 hereof.

Section 3.06 Notes Redeemed or Purchased in Part.

Upon surrender of a Note that is redeemed or purchased in part, the Company will issue and, upon receipt of an Authentication Order, the Trustee will authenticate for the Holder at the expense of the Company a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered.

The Company 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 designations; provided, however, that no such designation or rescission will in any manner relieve the Company of its obligation to maintain an office or agency in the City and State of New York for purposes of making payments on the Notes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

(a) Compliance with Laws. Without limiting Section 4.12, the Company will, and will cause each Restricted Subsidiary to, comply with all laws, ordinances or governmental rules or regulations to which each of them is subject (including ERISA, Environmental Laws, the USA PATRIOT Act and Regulation U, X and T of the Board of Governors of the Federal Reserve System) and will obtain and maintain in effect all licenses, certificates, permits, franchises and other governmental authorizations necessary to the ownership of their respective properties or to the conduct of their respective businesses, in each case to the extent necessary to ensure that non-compliance with such laws, ordinances or governmental rules or regulations or failures to obtain or maintain in effect such licenses, certificates, permits, franchises and other governmental authorizations could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

(b) Insurance.

(1) The Company will, and will cause each Restricted Subsidiary to, maintain, with financially sound and reputable insurers, insurance with respect to their respective properties and businesses against such casualties and contingencies, of such types, on such terms and in such amounts (including deductibles, co-insurance and self-insurance, if adequate reserves are maintained with respect thereto) (i) consistent with insurance that the Company and its Restricted Subsidiaries have in effect on the date of this Indenture and (ii) as is customary in the case of entities of established reputations engaged in the same or a similar business and similarly situated. If the Company or any Restricted Subsidiary fails to take out or maintain the full insurance coverage required by this Section 4.05(b), the Trustee or Collateral Agent (acting at the Direction of the Required Holders) may (but shall not be obligated to) obtain the required policies of insurance and pay the premiums on the same (but in no event shall the Trustee or Collateral Agent be obligated to pay such premiums). All amounts so advanced for the benefit of the Trustee or Collateral Agent shall become Note Obligations and the Note Parties shall forthwith pay such amounts to the Trustee to reimburse such Holders, together with interest from the date of payment in accordance with this Indenture.

(2) For any Mortgaged Property of the Note Parties which is, at any time, located within an area that has been identified by a Governmental Authority (including, by the Federal Emergency Management Agency) as a special flood hazard area, Holdings and its Subsidiaries shall also (i) maintain, or cause to be maintained, with a financially sound insurer, flood insurance in an amount reasonably satisfactory to the Collateral Agent and otherwise sufficient to comply with all applicable rules and

84

regulations promulgated pursuant to the Flood Insurance Laws, and (ii) deliver to the Collateral Agent evidence of such compliance in form and substance reasonably acceptable to the Collateral Agent, including, without limitation, evidence of annual renewals of such insurance. Each such insurance policy shall (i) indicate which Mortgaged Properties are located in a special flood hazard area and state the corresponding flood zone designation and, for each Mortgaged Property, the number of buildings located at such Mortgaged Property, (ii) indicate the flood insurance coverage and the deductible relating thereto, (iii) include a statement of values relating to all properties insured by the insurance policy, and (iv) be otherwise in form and substance reasonably satisfactory to the Collateral Agent. The Company will use commercially reasonable efforts to cause each flood insurance policy to provide that the insurer will give the Collateral Agent ten (10) day’s written notice of cancellation or non-renewal.

(3) Each of Holdings and the Company shall cause the Collateral Agent, to be named as secured parties or mortgagees and lender loss payees or additional insureds, as applicable, in a manner reasonably acceptable to the Collateral Agent, under all insurance policies required to be maintained by the Note Parties under clauses (a) and (b) above. The Company will use commercially reasonable efforts to cause such policy of insurance to contain a clause or endorsement requiring the insurer to give not less than thirty days prior written notice to the Collateral Agent in the event of cancellation of the policy for any reason whatsoever (other than cancellation for non-payment in which case no notice shall be required if unobtainable after use of commercially reasonable efforts), and, if obtainable (using commercially reasonable efforts), a clause or endorsement stating that the interest of the Collateral Agent shall not be impaired or invalidated by any act or neglect of any Note Party or the owner of any Real Estate for purposes more hazardous than are permitted by such policy.

(c) Maintenance of Properties. Each of Holdings and the Company will, and will cause each Restricted Subsidiary to, maintain, preserve, protect and keep, or cause to be maintained, preserved, protected and kept, all of their respective properties, including, without limitation, the Real Estate, in compliance with all applicable law of any Governmental Authority having jurisdiction over such property, in good repair, working order and condition or in the case of Inventory, in saleable, useable or rentable condition (other than ordinary wear and tear), and make all necessary renewals, replacements, modifications, improvements, upgrades, extensions and additions thereof or thereto in accordance with prudent industry practice, except, in each case, to the extent the failure to do so would not reasonably be expected to have a Material Adverse Effect.

Notwithstanding any other provision of this Section 4.09, the maximum amount of Indebtedness that the Company and its Restricted Subsidiaries may incur pursuant to this Section 4.09 shall not be deemed to be exceeded solely as a result of fluctuations in the exchange rate of currencies. The principal amount of any Permitted Refinancing Indebtedness, if incurred in a different currency from the Indebtedness being Refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such Permitted Refinancing Indebtedness is denominated that is in effect on the date of such refinancing.

(1) the Company (or a Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal to the Fair Market Value (measured as of the date of the definitive agreement with respect to the Asset Sale), of the assets or Equity Interests issued or sold or otherwise disposed of; and

(2) all of the aggregate consideration received by the Company and its Restricted Subsidiaries in the Asset Sale is in the form of cash, Cash Equivalents, Additional Assets or any combination thereof (“Cash Consideration”). For purposes of this provision, each of the following will be deemed to be Cash Consideration:

(i) any liabilities (as shown on the Company’s or any Restricted Subsidiary’s most recent balance sheet or in the notes thereto or, if incurred or accrued subsequent to the date of such balance sheet, such liabilities that would have been reflected on the Company’s or a Restricted Subsidiary’s consolidated balance sheet or in the notes thereto if such incurrence or accrual had taken place on or prior to the date of such balance sheet, as determined in good faith by the Company) of the Company or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated in right of payment to the Notes or any Notes Guarantor’s Notes Guarantee) that are (i) assumed by the transferee of any such assets (or a third party in connection with such transfer) or (ii) otherwise forgiven, cancelled or terminated in connection with the transaction with such transferee (other than intercompany debt owed to the Company or a Restricted Subsidiary); and

(ii) any securities, notes or other obligations received by the Company or any Restricted Subsidiary from such transferee that are, within 90 days after the consummation of such Asset Sale, converted by the Company or such Restricted Subsidiary into cash, to the extent of the cash received in that conversion.

98

(b) The Company will not, and will not permit any of its Restricted Subsidiaries to, make Asset Sales of Fixed Asset Priority Collateral in excess of an aggregate of $40.0 million in any calendar year or an aggregate of $150.0 million prior to the maturity date, in each case, without the consent of the Required Holders.

(c) Within 180 days after the receipt of any Net Proceeds from an Asset Sale, the Company or any of its Restricted Subsidiaries may apply an amount equal to those Net Proceeds at its option to any combination of the following:

(1) to the extent such Net Proceeds are from an Asset Sale of Fixed Asset Priority Collateral, to (i) repay or redeem Notes pursuant to an Asset Sale Offer or a redemption in accordance with Section 3.07 or (ii) to acquire Additional Assets or make Capital Expenditures, in each case that would constitute Fixed Asset Priority Collateral; and

(2) to the extent such Net Proceeds are from an Asset Sale that does not constitute Fixed Asset Priority Collateral, to (i) repay, redeem, purchase, defease or otherwise acquire, retire or terminate any Indebtedness secured by a Lien on such asset, (ii) to acquire Additional Assets or (iii) make Capital Expenditures in respect of any Permitted Business of the Company or any of its Restricted Subsidiaries.

(d) (1) The requirement of Sections 4.10(c)(1)(ii) and 4.10(c)(2)(ii) and (iii) shall be deemed to be satisfied if a bona fide binding contract committing to make the investment, acquisition or expenditure referred to therein is entered into by the Company or any Restricted Subsidiary, as the case may be, with a Person other than an Affiliate of the Company within the time period specified in Section 4.10(c) and such Net Proceeds are subsequently applied in accordance with such contract within six months following the date such agreement is entered into.

(2) Pending the final application of any Net Proceeds, the Company or any of its Restricted Subsidiaries may invest the Net Proceeds in any manner that is not prohibited by this Indenture; provided that pending such investment, all such Net Proceeds shall be deposited in the Sale Proceeds Account.

(3) To the extent the amount applied as provided in Section 4.13(c) is less than the amount of the Net Proceeds, the amount that is not so applied will constitute “Excess Proceeds.”

(e) Within 10 days after the aggregate amount of Excess Proceeds exceeds $20.0 million, the Company will, at its option, either (i) make an offer (an “Asset Sale Offer”) to all holders of Notes to purchase a principal amount Notes equal to the Excess Proceeds at a price not less than 100.0% of the principal amount thereof plus accrued and unpaid interest, if any, on the Notes to be redeemed to, but not including, the date of repurchase; provided that any Excess Proceeds remaining after an Asset Sale Offer will be used for a Mandatory Asset Sale Redemption, or (ii) issue a notice of redemption to redeem an amount of Notes equal to the Excess Proceeds of Notes (a “Mandatory Asset Sale Redemption”) at a redemption price equal to 100.0% of the principal amount thereof plus accrued and unpaid interest, if any, on the Notes to be redeemed to, but not including, the applicable redemption date.

99

(f) In the case of an Asset Sale Offer, such Asset Sale Offer shall be made to all holders of Notes. The Asset Sale Offer will remain open for a period of at least 20 Business Days following its commencement and not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the “Offer Period”). No later than three Business Days after the termination of the Offer Period (the “Purchase Date”), the Company will apply all of the Excess Proceeds (the “Offer Amount”) to the purchase of Notes (on a pro rata basis based on the principal amount of Notes surrendered, if applicable, except that any Notes represented by Global Notes will be selected by the Depositary based on the Depositary’s Applicable Procedures) or, if less than the Offer Amount has been tendered, all Notes and other such Indebtedness tendered in response to the Asset Sale Offer. Payment for any Notes so purchased will be made in the same manner as other principal payments are made. If the Purchase Date is on or after an interest Record Date and on or before the related Interest Payment Date, any accrued and unpaid interest will be paid to the Person in whose name a Note is registered at the close of business on such Record Date, and no additional interest will be payable to Holders who tender Notes pursuant to the Asset Sale Offer.

(g) Upon the commencement of an Asset Sale Offer, the Company will send a notice to each of the Holders, with a copy to the Trustee. The notice will contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The notice, which will govern the terms of the Asset Sale Offer, will state:

(1) that the Asset Sale Offer is being made pursuant to this Section 4.10 and the length of time the Asset Sale Offer will remain open;

(2) the Offer Amount, the purchase price and the expiration date of the Asset Sale Offer;

(3) that any Note not tendered or accepted for payment will continue to accrue interest;

(4) that, unless the Company defaults in making such payment, any Note accepted for payment pursuant to the Asset Sale Offer will cease to accrue interest after the Purchase Date;

(5) that Holders electing to have a Note purchased pursuant to an Asset Sale Offer may elect to have Notes purchased in denominations of $1,000 or an integral multiple of $1,000 in excess thereof, provided that the remaining part of any Note surrendered for purchase in part shall be $2,000 or an integral multiple of $1,000 in excess thereof;

(6) that Holders electing to have Notes purchased pursuant to any Asset Sale Offer will be required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Company, a depositary, if appointed by the Company, or a paying agent at the address specified in the notice prior to the expiration of the Offer Period;

100

(7) that Holders will be entitled to withdraw their election if the Company, the depositary or the paying agent, as the case may be, receives, not later than the expiration of the Offer Period, a telegram, electronic image scan, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Note purchased;

(8) that, if the aggregate principal amount of Notes surrendered by Holders thereof exceeds the Offer Amount allocated to the purchase of Notes in the Asset Sale Offer, the Trustee will select the Notes to be purchased on a pro rata basis based (except that any Notes represented by a Global Note shall be selected by the Depositary based on the Depositary’s Applicable Procedures) on the principal amount of Notes surrendered (with such adjustments as may be deemed appropriate by the Company so that only Notes in denominations of $1,000, or an integral multiple of $1,000 in excess thereof, will be purchased, provided that the remaining part of any Note surrendered for purchase in part shall be $2,000 or an integral multiple of $1,000 in excess thereof); and

(9) that holders whose Notes were purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered.

On or before the Purchase Date, the Company will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Notes or portions thereof tendered pursuant to the Asset Sale Offer and required to be purchased pursuant to this Section 4.10, or if Notes in an aggregate principal amount less than the Offer Amount allocated to the purchase of Notes in an Asset Sale Offer have been tendered, all Notes tendered, and will deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officer’s Certificate stating that such Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 4.10. The Company, the depositary for the Asset Sale Offer or the paying agent, as the case may be, will promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Company for purchase, and the Company will promptly issue a new Note, and the Trustee, upon receipt of an Authentication Order, will authenticate and mail or deliver (or cause to be transferred by book entry) such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof.

(h) In the case of a Mandatory Asset Sale Redemption, such redemption will be made pursuant to the provisions of Section 3.01 through 3.06 hereof.

101

(2) any employment agreement, customary benefit program or arrangement, equity award, equity option or equity appreciation agreement or plan with or for the benefit of officers, directors or employees of the Company or any of its Restricted Subsidiaries or any direct or indirect parent of the Company, entered into by the Company or any of its Restricted Subsidiaries or any direct or indirect parent of the Company in the ordinary course of business or in the ordinary course of business for a Permitted Business;

(3) transactions between or among any of the Company and its Restricted Subsidiaries, including between or among its Restricted Subsidiaries;

(6) customary compensation, severance or termination agreements, indemnification and other benefits made available to officers, directors, employees or consultants of the Company or a Subsidiary or Affiliate of the Company or any direct or indirect parent of the Company, including reimbursement or advancement of out of pocket expenses and provisions of officers’ and directors’ liability insurance;

(8) transactions with customers, clients, suppliers, or purchasers or sellers of goods or services, in each case in the ordinary course of business or in the ordinary course of business for a Permitted Business that, in the good faith judgment of the executive officers of the Company, are fair to the Company and its Restricted Subsidiaries, or are on terms at least as favorable as might reasonably have been obtained at such time from an unaffiliated Person;

(9) guarantees by the Company or any of its Restricted Subsidiaries of performance of obligations of the Company’s Unrestricted Subsidiaries in the ordinary course of business or in the ordinary course of business for a Permitted Business, except for guarantees of Indebtedness;

(12) any business arrangements pursuant to which Automatize LLC provides services to the Company in the ordinary course of business or in the ordinary course of business for a Permitted Business, including “manage last miles logistics,” software logistics and trucking logistics;

For purposes of determining compliance with this Section 4.12, (i) a Lien need not be incurred solely by reference to one category of Permitted Liens described in the definition thereof but is permitted to be incurred in part under any combination thereof and of any other available exemption and (ii) in the event that a Lien (or any portion thereof) meets the criteria of one or more of the categories of Permitted Liens, the Company will, in its sole discretion, be entitled to divide, classify or reclassify (based on circumstances existing at the time of such reclassification), in whole or in part, any such Lien (or any portion thereof) among one or more of such categories or clauses in any manner.

Section 4.13 LTV Maintenance.

(a) The Company will not permit the LTV as of any LTV Determination Date as set forth in the LTV Certificate to exceed 0.75 to 1.00; provided that no breach of this Section 4.13(a) shall constitute a Default or Event of Default, except to the extent that the Note Parties fail to effect an LTV Cure in respect thereof in accordance with Section 4.13(e).

(b) The Company shall engage the Appraiser as directed by the Required Holders to provide a determination of the Orderly Liquidation Value of the Notes Collateral as set forth in the initial Appraisal Report dated December 1, 2023 as of each March 31 and September 30 prior to the Maturity Date, beginning September 30, 2024 (each such date, a “LTV Determination Date”). The Company shall deliver to the Appraiser, the Holders and the Trustee no later 30 days after the applicable LTV Determination Date a schedule of the assets to be appraised as of such LTV Determination Date and shall cooperate with the Appraiser in preparing its field appraisal report on the Orderly Liquidation Value with respect to such assets (the “Appraisal Report”) as may be reasonably requested by the Appraiser.

(c) The Appraisal Report shall become final on the fifth Business Day following delivery thereof to the Company unless prior to the end of such period the Company shall send to the Appraiser a notice of its disagreement (“Notice of Disagreement”) specifying the nature and amount of any dispute. During the 60-day period following delivery of a Notice of Disagreement, the Company and the Appraiser in good faith shall seek to resolve any differences they may have. Any disputed items resolved in writing between the Company and the Appraiser within such 60-day period shall be final and binding with respect to such items. If

104

the Company and the Appraiser have not resolved all such differences by the end of such 60-day period, the Company and the Appraiser shall each make one written submission to an independent appraisal firm (an “Independent Appraisal Firm”) detailing their views as to the correct nature of the disputed items. In resolving any disputed item, the Independent Appraisal Firm may not assign a value to any item greater than the greatest value for such item claimed by either party or less than the smallest value for such item claimed by either party. The Independent Appraisal Firm shall be B. Riley Financial, Inc. or, if such firm is unwilling or unable to act, such other independent appraisal firm as shall be agreed in writing by the Company and the Required Holders. The Company shall instruct the Independent Appraisal Firm to render a written decision resolving the matters submitted to it as promptly as practicable, any in any event within 30 days following the submission thereof. The Independent Appraisal Firm’s determination of such disputed matter(s) shall be final and binding upon all parties absent demonstrable error.

(d) Within five Business Days following the finalization of the Appraisal Report pursuant to Section 4.13(c), the Company shall deliver to the Trustee a certificate (the “LTV Certificate”) of a Responsible Officer setting forth in reasonable detail the calculations of LTV as of the applicable LTV Determination Date.

(e) In the event that the LTV as of any LTV Determination Date as set forth in the LTV Certificate is greater than that permitted pursuant to Section 4.13(a), the Note Parties shall be required, to (i) redeem a principal amount Notes (a “Mandatory LTV Redemption”) at a redemption price equal to 100.0% of the principal amount thereof plus accrued and unpaid interest, if any, on the Notes to be redeemed to, but not including, the applicable redemption date; provided that such Mandatory LTV Redemption shall be made pursuant to the procedures set forth in Section 3.01 through 3.06 hereof, and/or (ii) provide additional Notes Collateral in accordance with the Note Documents, in each case (collectively or individually, as applicable) in an aggregate amount such that the Company shall be in compliance with Section 4.13(a) after giving pro forma effect to such payment and/or addition of Notes Collateral as of such LTV Determination Date (each of clauses (i) and (ii), an “LTV Cure”). The Note Parties shall complete the applicable LTV Cure(s) after any LTV Determination Date within 60 days following the delivery of the LTV Certificate.

Section 4.15 Offer to Repurchase Upon Change of Control.

(3) any Note not properly tendered will remain outstanding and continue to accrue interest;

(4) that, unless the Company defaults in the payment of the Change of Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer will cease to accrue interest on the Change of Control Payment Date;

(5) Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender such Notes, with the form entitled “Option of Holder to Elect Purchase” on the reverse of such Notes completed to the Paying Agent at the address specified in the notice or otherwise in accordance with DTC procedures, prior to the close of business on the third Business Day preceding the Change of Control Payment Date;

106

(7) if such notice is delivered prior to the occurrence of a Change of Control, stating that the Change of Control Offer is conditional on the occurrence of such Change of Control and describing each such condition; and

On the Change of Control Payment Date, the Company, the depositary, if any, appointed by the Company for such Change of Control Offer or a paying agent, as the case may be, will mail or remit to each Holder of Notes properly tendered and not withdrawn and accepted by the Company for payment the Change of Control Payment for such Notes (or, if all the Notes are then in global form, make such payment in accordance with the applicable procedures of the Depositary), and the Trustee will authenticate and mail or deliver (including by book-entry transfer) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes accepted for payment, if any; provided, however, that each new Note will be in a minimum principal amount of $2,000 or an integral multiple of $1,000 in excess of $2,000.

(c) Notwithstanding anything to the contrary in this Section 4.15, the Company will not be required to make a Change of Control Offer upon a Change of Control if (1) a third party makes the Change of Control Offer in the manner, at the time and otherwise in compliance with the requirements set forth in this Section 4.15 applicable to a Change of Control Offer made by the Company and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer or (2) the Company has previously or concurrently exercised their right to redeem all of the Notes as provided in Section 3.07 (which redemption is not subject to any conditions precedent). Notwithstanding anything to the contrary contained herein, a Change of Control Offer may be made in advance of a Change of Control, conditioned upon the consummation of such Change of Control, if a definitive agreement is in place for the Change of Control at the time of making the Change of Control Offer.

107

109

(b) The Board of Directors of the Company may at any time designate any Unrestricted Subsidiary of the Company to be a Restricted Subsidiary, provided that:

(i) such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of the Company of any outstanding Indebtedness of such Unrestricted Subsidiary and such designation will only be permitted if:

(1) the incurrence of such Indebtedness is permitted under Section 4.09, calculated on a pro forma basis as if such designation had occurred at the beginning of the applicable Reference Period,

(2) all Liens upon property or assets of such Unrestricted Subsidiary existing at the time of such designation would be permitted under Section 4.12; and

(3) no Default or Event of Default would be in existence following such designation; and

The Company shall deliver to the Trustee promptly, and in any event within 5 days after an Officer of the Company becoming aware of the existence of any Default or Event of Default, a written notice pursuant to Section 13.01 specifying the nature and period of existence thereof and what action the Company is taking or proposes to take with respect thereto.

Any such offer shall provide each Holder with sufficient information to enable it to make an informed decision with respect to such offer, and shall remain open for at least ten (10) Business Days. If the Required Holders accept such offer, the Company shall promptly notify the remaining Holders of such fact and the expiration date for the acceptance by Holders of such offer shall be extended by the number of days necessary to give each such remaining holder at least three (3) Business Days from its receipt of such notice to accept such offer. The Company will promptly cancel all Notes acquired by it or any Affiliate pursuant to any payment, prepayment or purchase of Notes pursuant to this Agreement and no Notes may be issued in substitution or exchange for any such Notes.

(5) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries, or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries (other than any Indebtedness owed to the Company or a Restricted Subsidiary), whether such Indebtedness or guarantee now exists, or is created after the date of this Indenture, if that default:

(A) is caused by a failure to pay the principal of such Indebtedness on its final scheduled maturity date after taking into account any grace period provided in such Indebtedness (a “Payment Default”); or

(B) results in the acceleration of such Indebtedness prior to its Stated Maturity,

and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates to an amount that exceeds $50.0 million; provided, that if prior to any acceleration of the Notes, any such Payment Default is cured or waived, or such Indebtedness is repaid, within a period of 60 days from the continuation of such Payment Default beyond the applicable grace period or the occurrence of such acceleration, as the case may be, such Event of Default and any consequential acceleration of the Notes shall be automatically rescinded, so long as such rescission does not conflict with any judgment, decree or applicable law;

(6) failure by the Company or any of its Restricted Subsidiaries to pay one or more final non-appealable judgments entered by a court or courts of competent jurisdiction aggregating to an amount that exceeds $50.0 million (to the extent not covered by insurance by a reputable and creditworthy insurer as to which the insurer has not disclaimed coverage), which judgment or judgments are not paid, satisfied, annulled, rescinded, discharged or stayed within 60 days after they become final and non-appealable;

114

115

(10) the occurrence of any of the following:

(A) except for expiration in accordance with its terms or amendment, modification, waiver, termination or release in accordance with its terms, any material provision of any Notes Collateral Document ceases for any reason to be fully enforceable; provided; no Event of Default shall be deemed to occur under this clause (10)(A) if such failure to be enforceable relates solely to Notes Collateral which, individually or in the aggregate, has a Fair Market Value of not more than $25.0 million;

(B) any Note Lien, individually or in the aggregate, ceases to be, or is not, a valid, perfected Lien and prior to all other Liens in accordance with the provisions hereof (subject only to (x) the Collateral and Guarantee Requirement and the Notes Collateral Documents and (y) Permitted Liens), or is terminated, revoked or declared void, except to the extent that any such loss of perfection results from the failure of the Collateral Agent to maintain possession of certificates, promissory notes or other instruments delivered to it representing securities or other assets pledged under the Notes Collateral Documents; provided; no Event of Default shall be deemed to occur under this clause (10)(B) if such loss of perfection relates solely to Notes Collateral which, individually or in the aggregate, has a Fair Market Value of not more than $25.0 million; or

(C) the Company or the Notes Guarantors, or any Person acting on behalf of any of them, denies or disaffirms, in writing, any obligation of the Company, any Notes Guarantor or any such other Person set forth in or arising under any Notes Collateral Document; and

Section 6.02 Acceleration.

In the case of an Event of Default (other than of a type specified in Section 6.01(7) or (8)), occurs and is continuing under this Indenture, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes (exclusive of Notes owned by the Company or any of its Affiliates) may declare the principal, interest and any other monetary obligations on all the then outstanding Notes issued under this Indenture to be due and payable immediately by notice in writing to the Company (with a copy to the Trustee, if such written notice is from Holders of at least 25% in principal amount of the then-outstanding Notes) specifying the Event of Default; provided, however, that after such acceleration, but before judgment or decree based on acceleration, the Required Holders may, under certain circumstances, rescind and annul such acceleration if all Events of Default, other than the nonpayment of accelerated principal and interest, have been cured or waived as provided in this Indenture. Notwithstanding the foregoing, in the case of an Event of Default pursuant to Section 6.01(7) or (8), all outstanding Notes will become due and payable immediately without further action or notice.

The Required Holders by written notice to the Company and the Trustee may, on behalf of all of the Holders of all the Notes, rescind an acceleration and its consequences hereunder, if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except nonpayment of principal of, premium, if any, on, or interest on, the Notes that has become due solely because of the acceleration) have been cured or waived.

116

Upon any Notes becoming due and payable under this Indenture, whether automatically or by declaration, such Notes will forthwith mature and the entire unpaid principal amount of such Notes, plus all accrued and unpaid interest thereon (including interest accrued thereon at the Default Rate), shall all be immediately due and payable, in each and every case without presentment, demand, protest or further notice, all of which are hereby waived. The Company acknowledges, and the parties hereto agree, that each holder of a Note has the right to maintain its investment in the Notes free from repayment by the Company (except as herein specifically provided for).

If all or any part of the Note Obligations in respect of the Note Documents or the Notes Guarantees becomes due and payable on or prior to the end of any period during which a Prepayment Premium or Make-Whole Amount would be due, whether on the Maturity Date, upon acceleration (whether by election or automatically), or on such other earlier date on which the Obligations in respect of the Note Documents, the Notes Guarantee or portion of the Note Obligations in respect of the Note Documents or the Notes Guarantee becomes due and payable as provided in the Note Documents or the Notes Guarantee, the applicable Prepayment Premium amount and the applicable Make-Whole Amount shall be due and payable on such repayment date, which Prepayment Premium and Make-Whole Amount shall constitute liquidated damages (it being agreed that the amount of damages that such Holder will suffer in each case are difficult to calculate). EACH OF THE NOTE PARTIES EXPRESSLY WAIVES (TO THE FULLEST EXTENT IT MAY LAWFULLY DO SO) THE PROVISIONS OF ANY PRESENT OR FUTURE STATUTE OR LAW THAT PROHIBITS OR MAY PROHIBIT THE COLLECTION OF ANY PREPAYMENT PREMIUM. Each of the Note Parties expressly agrees (to the fullest extent that it may lawfully do so) that: (A) each of the Prepayment Premium and Make-Whole Amount is reasonable and is the product of an arm’s length transaction between sophisticated business people, ably represented by counsel; (B) NO PREPAYMENT PREMIUM AMOUNT OR MAKE-WHOLE AMOUNT SHALL CONSTITUTE, OR BE DEEMED OR CONSIDERED TO BE, UNMATURED INTEREST ON THE NOTES OR OTHER AMOUNT AND NONE OF THE NOTE PARTIES SHALL ARGUE UNDER ANY CIRCUMSTANCE THAT ANY PREPAYMENT PREMIUM AMOUNT OR MAKE-WHOLE AMOUNT CONSTITUTES UNMATURED INTEREST ON THE NOTES; (C) the Prepayment Premium and Make-Whole Amount shall be payable when due notwithstanding the then prevailing market rates at the time payment is made; (D) there has been a course of conduct between the Holders and the Note Parties giving specific consideration in this transaction for such agreement to pay the Prepayment Premium and Make-Whole Amount; (E) each of the Note Parties shall be estopped hereafter from claiming differently than as agreed to in this paragraph; and (F) in view of the impracticability and extreme difficulty of ascertaining actual damages, the parties mutually agree that the Prepayment Premium and Make-Whole Amount are a reasonable calculation of the Holders’ lost profits as a result of any such prepayments and are not a penalty.

Section 6.03 Other Remedies.

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

117

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, whether accruing upon an Event of Default or otherwise, shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law.

Section 6.04 Waiver of Past Defaults.

The Required Holders may, on behalf of the Holders of all of the Notes, waive, by written notice to the Trustee, any existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of principal of, premium, if any, on, or interest on, the Notes (including a default in making a payment to purchase Notes pursuant to a Change of Control Offer or Asset Sale Offer in accordance with the terms of the applicable offer to repurchase). Upon notice to the Trustee of any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

Section 6.05 Control by Majority.

The Required Holders may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or (through the Trustee) the Collateral Agent or exercising any trust or power conferred on it. However, the Trustee may refuse, without liability, to follow any direction that the Trustee determines in its sole discretion conflicts with law or this Indenture or may be unduly prejudicial to the rights of other Holders of Notes or may involve the Trustee in personal liability. The Trustee shall be entitled to take any other action it considers in its sole discretion to be proper, and not inconsistent with any such direction from the Holders.

Section 6.06 [Reserved].

Section 6.07 Rights of Holders of Notes to Receive Payment.

Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal of, premium, if any, or interest on, the Note, on or after the respective due dates expressed in the Notes, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder.

Section 6.08 Collection Suit by Trustee.

If an Event of Default specified in Section 6.01(1) or (2) 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, premium, if any, and interest remaining unpaid on the Notes and, to the extent lawful, interest on overdue principal and interest and premium, if any, 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.

118

Section 6.09 Trustee May File Proofs of Claim.

The Trustee or Holders of more than 25.0% of the principal amount of the Notes then outstanding is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.10 Priorities.

Subject to the provisions of any Intercreditor Agreement in effect, if the circumstances described in Section 6.02 have occurred, or after the exercise of remedies provided for in this Section 6.10, or under any other Note Document (or after the Note Obligations have automatically become immediately due and payable in accordance with Section 6.02) or the Parent Guarantee, including in any bankruptcy or insolvency proceeding, any amounts received on account of the Note Obligations shall be applied (notwithstanding the provisions of Sections 8.2 and 8.3) by the Trustee and/or the Collateral Agent in the following order:

First, to payment of that portion of the Note Obligations constituting fees, indemnities, expenses and other amounts (other than principal and interest, but including attorneys’ fees payable under Section 7.07 hereof) payable to the Trustee and/or the Collateral Agent and/or the Trustee and/or the Collateral Agent in its capacity as such;

Second, to all fees, costs, indemnities, liabilities, obligations and expenses owing to any Purchaser with respect to this Indenture, the other Note Documents, or the Notes Collateral (but excluding the principal amount of and interest on the Note Obligations);

119

Fourth, to payment of that portion of the Note Obligations constituting fees, indemnities and other amounts (other than principal and interest) payable to the Purchasers (including attorneys’ fees payable under Section 7.07 hereof), ratably among them in proportion to the amounts described in this clause Fourth payable to them;

Fifth, to the payment of all other Note Obligations of the Note Parties that are due and payable to the Trustee and/or the Collateral Agent and the other Holders of Notes on such date, ratably based upon the respective aggregate amounts of all such Note Obligations owing to the Trustee and/or the Collateral Agent and the Holders of Notes on such date, until paid in full;

Last, the balance, if any, after all of the Obligations have been paid in full, to the Note Parties or as otherwise required by applicable law.

In carrying out the foregoing, (x) amounts received shall be applied in the numerical order provided until exhausted prior to the application to the next succeeding category and (y) each of the Persons entitled to receive a payment in any particular category shall receive an amount equal to its pro rata share of amounts available to be applied pursuant thereto for such category.

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 or the Collateral Agent for any action taken or omitted by it as a Trustee or Collateral Agent, as applicable, 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 faith of the claims or defenses made by the party litigant.

However, in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture (but need not investigate or confirm the accuracy of mathematical calculations or other facts stated therein).

Neither the Trustee nor the Collateral Agent will be under any obligation to exercise any of its rights and powers under this Indenture at the request of any Holders, unless such Holder has offered to the Trustee or the Collateral Agent, as applicable, indemnification and/or prefunding and/or security satisfactory to it against any loss, liability or expense. For the avoidance of doubt, while the Trustee shall be the sole party entitled to direct the Collateral Agent in respect of any matters relating to the Notes (and shall do so in accordance with Instructions given to the Trustee by Holders), the Trustee shall be under no obligation to provide any security or indemnity to the Collateral Agent, with such security or indemnity being provided directly by the relevant Holders to the Collateral Agent.

(f) The Trustee will not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law.

(a) The Trustee may conclusively rely upon any document believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document.

(b) Before the Trustee acts or refrains from acting, it may require an Officer’s Certificate or an Opinion of Counsel or both. The Trustee will not be liable for any action it takes or omits to take in good faith in reliance on such Officer’s Certificate or Opinion of Counsel. The Trustee may consult with counsel, and any other professional advisers, of its selection and the advice of such counsel, other professional advisers or any Opinion of Counsel will be full and complete authorization and protection from liability in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon.

(c) The Trustee may act through its attorneys and agents and will not be responsible for the misconduct or negligence of any attorney or agent appointed with due care.

(d) The Trustee will not be liable for any action it takes or omits to take in good faith that it believes to be authorized or within the rights or powers conferred upon it by this Indenture, the Notes Collateral Documents.

(e) Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Company will be sufficient if signed by an Officer of the Company, and the Company shall provide to the Trustee, promptly following request from the Trustee, an Officer’s Certificate setting out the names, titles and signatures of each Officer of the Company.

(f) The Trustee will be under no obligation to exercise any of the rights or powers vested in it by this Indenture or any other Note Document at the request or direction of any of the Holders unless such Holders have offered to the Trustee indemnity or security satisfactory to it against the losses, liabilities and expenses that might be incurred by it in compliance with such request or direction.

(g) The Trustee shall not be deemed to have notice or be charged with knowledge of any of a Default or an Event of Default unless written notice of any event which constitutes a Default or Event of Default is received by a Responsible Officer of the Trustee at the Corporate Trust Office of the Trustee by the Company or any other Obligor or by a Holder of the Notes, and such notice references the Notes and this Indenture and states that such notice is a notice of Default or Event of Default.

(h) In no event shall the Trustee be responsible or liable for special, indirect, punitive or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood or such loss or damage and regardless of the form of action.

122

(i) The rights, privileges, protections, immunities and benefits given to Trustee, including its right to be compensated and indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder and to each Agent, Custodian and other Person employed to act hereunder; provided (i) that any Paying Agent, Registrar, Custodian or other Person shall only be liable to extent of its gross negligence or willful misconduct; and (ii) in and during an Event of Default, only the Trustee and not any Paying Agent, Registrar, Custodian or other Person shall be subject to the prudent person standard in the circumstances set out in this Indenture.

(j) The permissive rights of the Trustee to take certain actions under this Indenture shall not be construed as a duty unless so specified herein.

(k) The Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties hereunder.

(l) The Trustee shall not have any obligation or duty to monitor, determine or inquire as to compliance, and shall not be responsible or liable for compliance, with restrictions on redemption, purchase or repurchase, as applicable, of minimum denominations imposed under this Indenture or under applicable law or regulation with respect of any redemption, purchase or repurchase, as applicable, of interest in any Note or any other security.

(m) The Trustee shall have the right to accept and act upon instructions, including funds transfer instructions (“Instructions”) given pursuant to this Indenture and delivered using Electronic Means; provided, however, that the Company and, as applicable, any other Obligor shall provide to the Trustee an incumbency certificate listing officers with the authority to provide such Instructions (“Authorized Officers”) and containing specimen signatures of such Authorized Officers, which incumbency certificate shall be amended by the Company and, as applicable, any other Obligor whenever a person is to be added or deleted from the listing. If the Company and, as applicable, any other Obligor elects to give the Trustee Instructions using Electronic Means and the Trustee in its discretion elects to act upon such Instructions, the Trustee’s understanding of such Instructions shall be deemed controlling. The Company and each Obligor understands and agrees that the Trustee cannot determine the identity of the actual sender of such Instructions and that the Trustee shall conclusively presume that directions that purport to have been sent by an Authorized Officer listed on the incumbency certificate provided to the Trustee have been sent by such Authorized Officer. The Company and each Obligor shall be responsible for ensuring that only Authorized Officers transmit such Instructions to the Trustee and that the Company, each Obligor and all Authorized Officers are solely responsible to safeguard the use and confidentiality of applicable user and authorization codes, passwords and/or authentication keys upon receipt by the Company and each Obligor. The Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from the its reliance upon and compliance with such Instructions notwithstanding such directions conflict or are inconsistent with a subsequent written instruction. The Company and each Obligor agrees: (i) to assume all risks arising out of the use of Electronic Means to submit Instructions to the Trustee, including without limitation the risk of the Trustee acting on unauthorized Instructions, and the risk of interception and misuse by third parties; (ii) that it is fully informed of the protections and risks associated with the various methods of transmitting Instructions to the Trustee and that there may be more secure methods of transmitting Instructions than the method(s) selected by the Company; (iii) that the security procedures (if any) to be followed in connection with its transmission of Instructions provide to it a commercially reasonable degree of protection in light of its particular needs and circumstances; and (iv) to notify the Trustee immediately upon learning of any compromise or unauthorized use of the security procedures.

123

Section 7.03 Individual Rights of Trustee.

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company, the Notes Guarantors or any their Affiliates 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 after a Default has occurred and is continuing) it must eliminate such conflict within 90 days, apply to the SEC for permission to continue as Trustee (if this Indenture has been qualified under the TIA) or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Section 7.10.

Section 7.04 Trustee and Collateral Agent’s Disclaimer.

Neither the Trustee nor the Collateral Agent will be responsible for and neither of them makes any representation as to the validity, sufficiency or adequacy of this Indenture, the Notes, any other Note Documents or any offering documents relating to the Notes. Neither of them shall 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, neither of them will be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and neither of them will be responsible for any statement or recital herein or any statement in the Notes, the Note Documents or any other document in connection with the sale of the Notes or pursuant to this Indenture other than the Trustee’s certificate of authentication. Neither of them is accountable for the content or accuracy of any document provided to them. The Trustee has no responsibilities or obligations in respect of the Notes Collateral, the Notes Collateral Documents or any matters related to them, which are solely the responsibilities or obligations of the relevant Obligors and the Collateral Agent as the party taking the benefit of the Notes Collateral and the Notes Collateral Documents for and on behalf of the Holders and the Trustee. Each Holder by its acceptance of a Note explicitly exonerates, discharges and fully holds harmless the Trustee and the Collateral Agent from and against any liability in respect of the Notes Collateral and the Notes Collateral Documents.

Section 7.05 Direction of the Required Holders. With respect to each reference herein to (i) documents, agreements or other matters being “satisfactory,” “acceptable,” “reasonably satisfactory” or “reasonably acceptable” (or any expression of similar import) to the Collateral Agent and/or the Trustee, the Collateral Agent and/or the Trustee shall act on a Direction of the Required Holders and/or (ii) any matter requiring the consent or approval of, or a determination by, the Collateral Agent and/or the Trustee, the Collateral Agent and/or the Trustee shall act upon a Direction of the Required Holders. The Collateral Agent and the Trustee shall be entitled to rely upon, and shall not incur any liability for relying upon, any written direction or instruction from the Required Holders that is purported to be a Direction of the Required Holders, and the Collateral Agent shall not have any responsibility to independently determine whether such direction has in fact been authorized by the Required Holders.

Section 7.06 [Reserved].

124

Section 7.07 Compensation and Indemnity.

(a) The Company will pay to the Trustee from time to time such compensation for its acceptance of this Indenture and services hereunder (including as Paying Agent and Registrar) as the Company and the Trustee shall agree in writing from time to time. The Trustee’s compensation will not be limited by any law on compensation of a trustee of an express trust. The Company will reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses will include the properly incurred compensation, disbursements and expenses of the Trustee’s agents and counsel.

(b) The Company and the Notes Guarantors will jointly and severally indemnify, defend and protect the Trustee (acting in any capacity hereunder) and the Collateral Agent, their respective officers, directors, employees and agents (each an “Indemnified Person”), and hold each Indemnified Person harmless against, any and all losses, damages, claims, liabilities, costs or expenses (including properly incurred attorneys’ fees and any court costs) suffered or incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Company and the Notes Guarantors (including this Section 7.07) and defending itself against any claim (whether asserted by the Company, the Notes Guarantors, any Holder or any other Person) or liability in connection with the acceptance, exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, liability or expense may be attributable to its negligence or willful misconduct as determined by a final, non-appealable judgment of a court of competent jurisdiction. An Indemnified Person will notify the Company promptly of any claim for which it may seek indemnity. Neither the Company nor any Notes Guarantor need pay for any settlement made without its consent, which consent will not be unreasonably withheld.

(c) The obligations of the Company and the Notes Guarantors under this Section 7.07 will survive the satisfaction and discharge of this Indenture and the resignation, removal or retirement of the Trustee and the Collateral Agent.

(d) To secure the Company’s and the Notes Guarantors’ payment obligations in this Section 7.07, the Trustee will 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 of, premium, if any, on, or interest on, particular Notes. Such Lien will survive the resignation or removal of the Trustee and the satisfaction and discharge of this Indenture.

(e) When an Indemnified Person incurs expenses or renders services after an Event of Default specified in Section 6.01(8) or (9) 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.

Within one year after the successor Trustee takes office, the Required Holders may appoint a successor Trustee to replace the successor Trustee appointed by the Company.

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

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

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

127

Section 7.13 Additional Rights of the Trustee

Further, notwithstanding any other provisions of this Indenture to the contrary, should the Trustee, in its sole judgment, determine at any time that its acting under this Indenture has resulted in its being in non-compliance with any applicable anti-money laundering or anti-terrorist legislation, Sanctions, regulation or guideline, then it shall have the right to resign on 10 days’ written notice to the other parties hereto.

Notwithstanding anything in this Article 9 to the contrary, no amendment of, or supplement or waiver to, this Indenture or the other Note Documents pursuant to this Section 9.01 shall be permitted to be effected if such amendment, supplement or waiver is in violation of or inconsistent with the terms of the Notes Collateral Documents. No amendment of, or supplement or waiver to, the Notes Collateral Documents shall be permitted to be effected without the consent of the Collateral Agent.

Section 9.02 With Consent of Holders of Notes.

Except as provided in Section 9.01 and this Section 9.02, the Company, the Notes Guarantors, the Trustee and the Collateral Agent (as applicable) may amend or supplement the Note Documents (subject to the terms of the Notes Collateral Documents, in the case of the Notes Collateral Documents) or the Parent Guarantee, and any existing Default or Event of Default or compliance with any provision of the Note Documents or the Parent Guarantee may be waived, in each case, with the consent of the Required Holders (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Notes).

(9) amend, change or otherwise modify the definition of “Required Holders”;

(10) make any material change in the provisions set forth in Section 3.07 or Article 11;

(11) amend, waive or otherwise modify the definition of any other provision under this Indenture in a manner that would alter the pro rata treatment, pro rata sharing of payments or the order of payment required hereby; or

131

Without the consent of each Holder of Notes then outstanding and adversely affected thereby, no amendment, supplement or waiver may (i) release all or substantially all of the Notes Collateral from the Notes Lien of the applicable Notes Collateral Documents with respect to such Notes, (ii) subordinate, or have the effect of subordinating, all or substantially all of the Obligations to any other Indebtedness, or the all or substantially all of “Guaranteed Obligations” (as defined in the Parent Guaranty) under the Parent Guaranty to any other Indebtedness of the Parent, (iii) subordinate, or have the effect of subordinating, all or substantially all of the Liens securing the Obligations to Liens securing any other Debt, and/or (iv) change the order of application of proceeds from Notes Collateral, including any “default waterfall” or similar provision, under any Note Document; provided that sub-clauses (ii), (iii) and (iv) shall not apply to any debtor-in-possession financing and use of cash collateral in compliance with any Intercreditor Agreement.

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 9.05, the Trustee will join with the Company and the Notes Guarantors in the execution of such amended or supplemental indenture or other Note Document unless such amended or supplemental indenture directly affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but will not be obligated to, enter into such amended or supplemental indenture.

It is not necessary for the consent of the Holders of Notes under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it is sufficient if such consent approves the substance thereof.

After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company will send to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to give such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver.

Furthermore, no amendment or modification of the Calculation Agent’s rights or duties hereunder may be made without the prior written consent of the Calculation Agent.

Section 9.03 Revocation and Effect of Consents.

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

132

Section 9.04 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, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver.

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

Section 9.05 Trustee and Collateral Agent to Sign Amendments, etc.

The Trustee and, if applicable, the Collateral Agent will sign any amended or supplemental indenture, or any amendment and supplement to any other Note Document, authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee and the Collateral Agent. In executing any amended or supplemental indenture or amendment or supplement to any other Note Document, the Trustee and the Collateral Agent shall be entitled to receive and (subject to Section 7.01 hereof in the case of the Trustee) will be fully protected in relying upon, in addition to the documents required by Section 13.02 hereof, an Officer’s Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture and that such amendment or supplement is the legally valid and binding obligation of the Company, enforceable against them in accordance with its terms, subject to customary exceptions.

Section 9.06 Solicitation of Holders of Notes.

(a) Solicitation. The Company will provide each holder of a Note with sufficient information, sufficiently far in advance of the date a decision is required, to enable such holder to make an informed and considered decision with respect to any proposed amendment, supplement, waiver or consent in respect of any of the provisions hereof or of any Note Document. The Company will deliver executed or true and correct copies of each amendment, supplement waiver or consent effected pursuant to this Article 9 or any Note Document to each Holder promptly following the date on which it is executed and delivered by, or receives the consent or approval of, the requisite Holders.

(b) Payment. The Company will not directly or indirectly pay or cause to be paid any remuneration, whether by way of supplemental or additional interest, fee or otherwise, or grant or cause to be granted any security or provide other credit support, to any Holder as consideration for or as an inducement to the entering into by such Holder of any waiver, supplement or amendment of any of the terms and provisions hereof or of any Note Document unless such remuneration is concurrently paid, or security is concurrently granted or other credit support concurrently provided, on the same terms, ratably to each Holder even if such Holder did not consent to such waiver, supplement or amendment.

(a) Subject to this Article 10, each Notes Guarantor hereby absolutely, unconditionally and irrevocably guarantees, jointly with the other Notes Guarantors and severally, as primary obligor and not merely as surety, to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and the Collateral Agent and their respective successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Company hereunder or thereunder, that:

(1) the principal of, premium, if any, on, and interest on, the Notes will be promptly paid in full when due, whether at Stated Maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of, premium, if any, on, and interest premiums, fees, indemnities, contract causes of action, costs, expenses or otherwise on, the Notes, if lawful, and all other Obligations of the Company, whether now or hereafter existing, to the Holders or the Trustee hereunder or thereunder will be promptly paid in full, all in accordance with the terms hereof and thereof; and

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

Failing payment when due of any amount so guaranteed for whatever reason, the Notes Guarantors will be jointly and severally obligated to pay the same immediately. Each Notes Guarantor agrees that this is a guarantee of payment (whether or not any bankruptcy or similar proceeding shall have stayed the accrual of collection of any of the foregoing Obligations or operated as a discharge thereof) and not a guarantee of collection, and is in no way conditioned upon any requirement that the Collateral Agent first attempt to collect any portion of the Obligations from the Company or any Notes Guarantor or resort to any other means of obtaining payment.

Without limiting the generality of the foregoing, each Notes Guarantor’s liability shall extend to all amounts that constitute part of the foregoing Obligations and would be owed by any other Notes Guarantor to any Secured Party but for the fact that they are unenforceable or not allowable due to the existence of a bankruptcy, reorganization or similar proceeding involving such other Notes Guarantor.

(b) The Notes Guarantors hereby agree that their obligations hereunder are unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Notes Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that its Notes Guarantee will not be discharged except by complete performance of the obligations contained in the Notes and this Indenture.

134

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

(d) Each Notes Guarantor agrees that it will not be entitled to any right of subrogation in relation to the Holders in respect of any Obligations guaranteed hereby until payment in full of all Obligations guaranteed hereby. Each Notes Guarantor further agrees that, as between the Notes Guarantors, on the one hand, and the Holders, the Collateral Agent and the Trustee, on the other hand, (1) the maturity of the Obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Article 10, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Obligations guaranteed hereby, and (2) in the event of any declaration of acceleration of such Obligations as provided in Article 6 hereof, such Obligations (whether or not due and payable) will forthwith become due and payable by the Notes Guarantors for the purpose of this Article 10. The Notes Guarantors will have the right to seek contribution from any non-paying Notes Guarantor so long as the exercise of such right does not impair the rights of the Holders under this Article 10.

Section 10.02 Limitation on Notes Guarantor Liability.

(a) Each Notes Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Notes Guarantee of such Notes Guarantor not constitute a fraudulent transfer, conveyance or preference, financial assistance or a transfer at undervalue, for purposes of any Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal, state, provincial or other applicable U.S. or foreign law to the extent applicable to any Notes Guarantee (collectively, “Fraudulent Transfer Laws”) or that the obligations of such Notes Guarantor under this Article 10 would otherwise be held or determined to be void, voidable, invalid or unenforceable on account of the amount of its liability under this Article 10. To effectuate the foregoing intention, the Trustee, the Collateral Agent, the Holders and the Notes Guarantors hereby irrevocably agree that the Obligations of each Notes Guarantor under this Indenture at any time shall be limited to the maximum amount equal to the largest amount that would not, at such time, result in the Obligations of such Notes Guarantor under this Indenture subject to avoidance as a fraudulent transfer or conveyance but only to the extent that any Fraudulent Transfer Law has been found in a final non-appealable judgment of a court of competent jurisdiction to be applicable to such obligations as of such date, and in each case:

(b) after giving effect to all liabilities of such Guarantor, contingent or otherwise, that are relevant under the Fraudulent Transfer Laws, but specifically excluding: (i) any liabilities of such Notes Guarantor in respect of intercompany indebtedness to the Company or any other Subsidiary of Holdings to the extent that such indebtedness would be discharged in an amount equal to the amount paid by such Notes Guarantor hereunder; (ii) any liabilities of such Notes Guarantor under this Indenture; and (iii) any liabilities of such Notes Guarantor under each of its other guarantees of and joint and several incurrence of Indebtedness, in each case which contain a limitation as to maximum amount substantially similar to that set forth in this

135

Section 10.02(a) (each such other guarantee and joint and several incurrence of Indebtedness entered into on the date this Indenture becomes effective, a “Competing Guaranty”) to the extent such Notes Guarantor’s liabilities under such Competing Guaranty exceed an amount equal to (A) the aggregate principal amount of such Notes Guarantor’s obligations under such Competing Guaranty (notwithstanding the operation of that limitation contained in such Competing Guaranty that is substantially similar to this Section 10.02(a)), multiplied by (B) a fraction (X) the numerator of which is the aggregate principal amount of such Guarantor’s obligations under such Competing Guaranty (notwithstanding the operation of that limitation contained in such Competing Guaranty that is substantially similar to this Section 10.02(a)), and (Y) the denominator of which is the sum of (I) the aggregate principal amount of the obligations of such Notes Guarantor under all other Competing Guaranties (notwithstanding the operation of those limitations contained in such other Competing Guaranties that are substantially similar to this Section 10.02(a)), (II) the aggregate principal amount of the obligations of such Guarantor under this Indenture (notwithstanding the operation of this Section 10.02(a)), and (III) the aggregate principal amount of the obligations of such Notes Guarantor under such Competing Guaranty (notwithstanding the operation of that limitation contained in such Competing Guaranty that is substantially similar to this Section 10.02(a)); and

(c) after giving effect as assets to the value (as determined under the applicable provisions of the Fraudulent Transfer Laws) of any rights to subrogation, reimbursement, indemnification or contribution of such Notes Guarantor pursuant to applicable requirements of any Governmental Authority or pursuant to the terms of any agreement.

For purposes hereof, “Bankruptcy Law” means any proceeding of the type referred to in Sections 6.01(7) or 6.01(8) or the Bankruptcy Code, or any similar foreign, federal or state law for the bankruptcy, insolvency, or reorganization, or relief of debtors.

Section 10.03 Notation of Notes Guarantee Not Required.

The Notes Guarantee of any Notes Guarantor shall be evidenced solely by its execution and delivery of this Indenture (or, in the case of any Notes Guarantor that is not party to this Indenture on the date hereof, a supplemental indenture hereto), and no Notes Guarantor shall be required to make a notation on the Notes to reflect any Notes Guarantee.

Each Notes Guarantor hereby agrees that its Notes Guarantee set forth in Section 10.01 will remain in full force and effect notwithstanding the absence of a notation of such Notes Guarantee on each Note.

The delivery of any Note by the Trustee, after the authentication thereof hereunder, will constitute due delivery of the Notes Guarantee set forth in this Indenture or any supplemental indenture on behalf of the Notes Guarantors.

Section 10.04 Releases.

The Notes Guarantee of a Notes Guarantor (other than the Company), together with all of its other obligations under this Indenture, shall be unconditionally released and discharged upon the consummation of any of the following transactions or designations not prohibited by, and, if set forth hereunder or thereunder, consummated in accordance with the applicable provisions of,

136

this Indenture or the other Note Documents; provided, that the Required Holders shall have consented in writing to such transaction or designation within ten Business Days of receipt of a written notice from the Company describing such transaction in reasonable detail (provided further, that such consent shall be deemed given by the Required Holders if the Required Holders have not denied providing such consent in writing within such ten Business Day period):

(a) concurrently with any sale or other disposition of all or substantially all of the properties or assets of that Notes Guarantor (including by way of merger, amalgamation or consolidation) to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company; provided, that such sale or disposition (including by way of merger, amalgamation or consolidation) is not prohibited by this Indenture;

(b) concurrently with any sale or other disposition of not less than a majority of the Capital Stock of that Notes Guarantor to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company; provided, that such sale or disposition is not prohibited by this Indenture;

(c) if the Company designates such Notes Guarantor as an Unrestricted Subsidiary in accordance with the applicable provisions of this Indenture provided, that such designation was consummated with a bona fide legitimate business purpose;

(d) [reserved];

(e) upon the liquidation or dissolution of such Notes Guarantor, provided no Default or Event of Default has occurred that is continuing and such liquidation or dissolution was consummated with (i) a bona fide and legitimate business purpose, and (ii) not in contemplation of adversely affecting the holders of the Notes’ interests in the Notes Guarantees and Note Lien with respect to such Notes Guarantor;

(f) in connection with the merger, amalgamation or consolidation of such Notes Guarantor with or into the Company or any other Notes Guarantor, where the Company or such other Notes Guarantor is the surviving Person in such merger, amalgamation or consolidation, or upon the liquidation of a Notes Guarantor following the transfer of all or substantially all of its assets, in each case, in a transaction that complies with the applicable provisions of this Indenture; provided no Default or Event of Default occurs as a result thereof or has occurred and is continuing;

(g) as described in Article 9;

in each case, upon delivery to the Trustee by the Company of an Officer’s Certificate described in the immediately succeeding paragraph.

The Trustee shall, at the Company’s expense, execute any documents reasonably requested by the Company in order to evidence the release of any Notes Guarantor from its obligations under its Notes Guarantee; provided that, prior to executing such documents, the Trustee shall be entitled to receive from the Company an Officer’s Certificate and, if requested, an Opinion of Counsel to the effect that the conditions precedent to such release have been satisfied. Any failure by the Trustee to execute such documents shall, however, not affect the

137

automatic release and discharge of the Notes Guarantee and the other obligations of any Notes Guarantor as contemplated by the foregoing provisions of this Section 10.04. Any Notes Guarantor not released from its obligations under its Notes Guarantee as provided in this Section 10.04 will remain liable for the full amount of principal of, premium, if any, on, and interest on, the Notes and for the other obligations of such Notes Guarantor under this Indenture as provided in this Article 10.

In addition, the Company must deliver an Officer’s Certificate stating that all conditions precedent to satisfaction and discharge have been satisfied and an Opinion of Counsel (which Opinion of Counsel may be subject to customary assumptions and exclusions) to the Trustee.

BY ACCEPTING A NOTE EACH HOLDER WILL BE DEEMED TO HAVE IRREVOCABLY AGREED TO THE FOREGOING PROVISIONS OF CLAUSES (A) AND (B) OF THIS SECTION 12.01 AND SHALL BE BOUND BY THOSE AGREEMENTS TO THE FULLEST EXTENT PERMITTED BY LAW.

Each Notes Guarantor agrees that its obligation in respect of any Original Currency due from it hereunder shall, notwithstanding any judgment or payment in such other currency, be discharged only to the extent that, on the Business Day following the date the Agent receives payment of any sum so adjudged to be due hereunder in the Second Currency, the Agent may, in accordance with normal banking procedures, purchase, in the New York foreign exchange market, the Original Currency with the amount of the Second Currency so paid; and if the amount of the Original Currency so purchased or could have been so purchased is less than the amount originally due in the Original Currency, each Obligor agrees as a separate obligation and notwithstanding any such payment or judgment to indemnify the Collateral Agent against such loss. The term “rate of exchange” in this Section 13.18 means the spot rate at which the Agent, in accordance with normal practices, is able on the relevant date to purchase the Original Currency with the Second Currency, and includes any premium and costs of exchange payable in connection with such purchase.

Any reference in any Note Documents to a merger, consolidation, amalgamation, assignment, sale, disposition or transfer, or similar term, shall be deemed to apply to a Division of or by a limited liability company, or an allocation of assets to a series of a limited liability company (or the unwinding of such a Division or allocation), as if it were a merger, consolidation, amalgamation, assignment, sale, Disposition or transfer, or similar term, as applicable, to, of or with a separate Person.

Certificate of Authentication:

This is one of the Notes referred to in the within-mentioned Indenture:

A-3

[Reverse of Note]

Senior Secured Floating Rate Notes due 2029

Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

(1) Amortization of Principal. The Company will pay:

(a) $10,000,000 aggregate principal amount of Notes (or such lesser principal amount as shall then be outstanding) on each of June 30, 2024, September 30, 2024 and December 31, 2024; and

(b) $15,000,000 aggregate principal amount of Notes (or such lesser principal amount as shall then be outstanding) at the end of each calendar quarter thereafter,

in each case at 100.0% of the principal amount thereof and without payment of a Make-Whole Premium or any redemption premium or any other premium, provided that upon any partial redemption or prepayment of the Notes pursuant to Sections 3.07, 4.10, 4.13, or 4.15 of the Indenture, the principal amount of each required prepayment of the Notes becoming due under this Section 1 of this Note on and after the date of such redemption or prepayment shall be reduced in the same proportion as the aggregate unpaid principal amount of the Notes is reduced as a result of such prepayment or purchase.

The entire unpaid principal balance of the Notes shall be due and payable on the Maturity Date thereof, together with accrued and unpaid interest therein through but not including such date.

(2) INTEREST. All outstanding Notes shall bear interest on the unpaid principal amount thereof (including, to the extent permitted by law, on interest thereon not paid when due) from the date of issuance until paid in full in cash at a fluctuating per annum rate equal to Adjusted Term SOFR plus the Applicable Margin (each as defined below), but not in excess of the Maximum Rate (as defined below). The Company will pay interest, if any, quarterly in arrears on each Interest Payment Date (as defined below). Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance. All computations of fees and interest shall be made on the basis of a 360-day year comprised of twelve 30-day months and actual days elapsed.

Upon the occurrence and during the continuance of an Event of Default, and upon the request of the Required Holders by notice to the Company and the Calculation Agent, the Calculation Agent shall require that the Company pay interest at a rate per annum equal at all times to 2.00% per annum above the rate per annum required to be paid (“Default Interest”) on:

(a) the aggregate outstanding principal amount of the Notes, and

A-4

(b) to the fullest extent permitted by applicable law, the amount of any interest, fee or other amount payable under the Notes or any other Note Document to any Agent or any holder that is not paid when due, from the date such amount shall be due until such amount shall be paid in full, (x) on each SOFR Interest Payment Date following the occurrence and during the continuance of an Event of Default or (y) on demand; provided, however, that following the making of the request or the granting of the consent specified by Section 6.02 of the Indenture to authorize the Trustee to declare the Notes due and payable pursuant to the provisions of Section 6.02 of the Indenture, Default Interest shall accrue and be payable hereunder whether or not previously required by the Trustee. Payment or acceptance of the increased rates of interest provided herein is not a permitted alternative to timely payment and shall not constitute a waiver of any Event of Default or otherwise prejudice or limit any rights or remedies of the Trustee or any Holder.

In connection with the use or administration of Term SOFR, the Calculation Agent will have the right to make Conforming Changes from time to time and, notwithstanding anything to the contrary in the Indenture or in any other Note Document, any amendments implementing such Conforming Changes will become effective without any further action or consent of any other party to the Notes or any other Note Document. The Calculation Agent will promptly notify the Company and the holders of the effectiveness of any Conforming Changes in connection with the use or administration of Term SOFR.

If at any time the Calculation Agent determines (which determination shall be conclusive absent manifest error) that (i) the circumstances set forth in the immediately succeeding paragraph have arisen and such circumstances are unlikely to be temporary or (ii) the circumstances set forth in the immediately succeeding paragraph have not arisen but the supervisor for the administrator of the SOFR Rate or a Governmental Authority having jurisdiction over the Calculation Agent has made a public statement identifying a specific date after which the SOFR Rate shall no longer be used for determining interest rates for loans (or, after which, the SOFR Rate is no longer required to be published), then the Calculation Agent and the Company shall endeavor to establish an alternate rate of interest to the SOFR Rate that gives due consideration to the then prevailing market convention for determining a rate of interest for syndicated loans in the United States at such time, and shall enter into an amendment to this Note to reflect such alternate rate of interest and such other related changes to this Note as may be applicable. Such amendment shall become effective without any further action or consent of any other party to the Notes so long as the Calculation Agent shall not have received, within five (5) Business Days of the date notice of such alternate rate of interest is provided to the Holders, a written notice from the Required Holders stating that such the Holders object to such amendment; provided that, if such alternate rate of interest shall be less than 3.00%, such rate shall be deemed to be 3.00% for the purposes of the Notes.

Notwithstanding anything to the contrary herein or in any other Note Document, at any time (including in connection with the implementation of a Benchmark Replacement), (i) if the then-current Benchmark is the Term SOFR Reference Rate and either (A) any tenor for such Benchmark is not displayed on a screen or other information service that publishes such rate from time to time as selected by the Calculation Agent in its reasonable discretion or (B) the regulatory supervisor for the administrator of such Benchmark has provided a public statement or publication of information announcing that any tenor for such Benchmark is not or will not be representative, then the Calculation Agent may modify the definition of “Interest Period” (or any similar or analogous definition) for any Benchmark settings at or after such time to remove such unavailable

A-5

or non-representative tenor and (ii) if a tenor that was removed pursuant to clause (i) above either (A) is subsequently displayed on a screen or information service for a Benchmark (including a Benchmark Replacement) or (B) is not, or is no longer, subject to an announcement that it is not or will not be representative for a Benchmark (including a Benchmark Replacement), then the Calculation Agent may modify the definition of “Interest Period” (or any similar or analogous definition) for all Benchmark settings at or after such time to reinstate such previously removed tenor.

In no event shall any interest rate provided for hereunder exceed the maximum rate legally chargeable under applicable law with respect to the Notes (the “Maximum Rate”). If for any interest period, any interest rate, absent such limitation, would have exceeded the Maximum Rate, then the interest rate for that period shall be the Maximum Rate, and, if in future periods, that interest rate would otherwise be less than the Maximum Rate, then that interest rate shall remain at the Maximum Rate until such time as the amount of interest paid hereunder equals the amount of interest which would have been paid if the same had not been limited by the Maximum Rate. In the event that, upon payment in full of the Note Obligations, the total amount of interest paid or accrued under the terms of this Note is less than the total amount of interest which would, but for this paragraph, have been paid or accrued if the interest rate otherwise set forth in this Note had at all times been in effect, then the Company shall, to the extent permitted by applicable law, pay the Trustee, for the account of the applicable Holders, an amount equal to the excess of (a) the lesser of (i) the amount of interest which would have been charged if the Maximum Rate had, at all times, been in effect or (ii) the amount of interest which would have accrued had the interest rate otherwise set forth in this Note, at all times, been in effect over (b) the amount of interest actually paid or accrued under this Note. If a court of competent jurisdiction determines that the Trustee and/or any Holder has received interest and other charges hereunder in excess of the Maximum Rate, such excess shall be deemed received on account of, and shall automatically be applied to reduce, the Note Obligations other than interest, and if there are no Note Obligations outstanding, the Trustee and/or such Holder shall refund to the Company such excess.

“Adjusted Term SOFR” means, for purposes of any calculation, the rate per annum equal to (a) Term SOFR for such calculation plus (b) the Term SOFR Adjustment; provided that if Adjusted Term SOFR as so determined shall ever be less than the Floor, then Adjusted Term SOFR shall be deemed to be the Floor. Adjusted Term SOFR shall be calculated by the Calculation Agent.

“Applicable Margin” means 7.25%.

“Available Tenor” means, as of any date of determination and with respect to the then-current Benchmark, as applicable, (a) if such Benchmark is a term rate, any tenor for such Benchmark (or component thereof) that is or may be used for determining the length of an interest period pursuant to this Agreement or (b) otherwise, any payment period for interest calculated with reference to such Benchmark (or component thereof) that is or may be used for determining any frequency of making payments of interest calculated with reference to such Benchmark pursuant to the Notes, in each case, as of such date and not including, any tenor for such Benchmark that is then-removed from the definition of “Interest Period”, following the unavailability of tenor of such Benchmark.

A-6

“Benchmark” means, initially, the Term SOFR Reference Rate; provided that if a Benchmark Transition Event has occurred with respect to the Term SOFR Reference Rate or the then-current Benchmark, then “Benchmark” means the applicable Benchmark Replacement to the extent that such Benchmark Replacement has replaced such prior benchmark rate pursuant to the terms hereto.

“Benchmark Replacement” means, with respect to any Benchmark Transition Event, the first alternative set forth in the order below that can be determined by the Calculation Agent for the applicable Benchmark Replacement Date:

(a) Daily Simple SOFR; or

(b) the sum of: (i) the alternate benchmark rate that has been selected by the Calculation Agent and the Company giving due consideration to (A) any selection or recommendation of a replacement benchmark rate or the mechanism for determining such a rate by the Relevant Governmental Body or (B) any evolving or then-prevailing market convention for determining a benchmark rate as a replacement to the then-current Benchmark for Dollar-denominated syndicated credit facilities and (ii) the related Benchmark Replacement Adjustment.

If the Benchmark Replacement as determined pursuant to clause (a) or (b) above would be less than the Floor, the Benchmark Replacement will be deemed to be the Floor for the purposes of the Notes, the other Note Documents.

“Benchmark Replacement Adjustment” means, with respect to any replacement of the then-current Benchmark with an Unadjusted Benchmark Replacement, the spread adjustment, or method for calculating or determining such spread adjustment, (which may be a positive or negative value or zero) that has been selected by the Calculation Agent and the Company giving due consideration to (a) any selection or recommendation of a spread adjustment, or method for calculating or determining such spread adjustment, for the replacement of such Benchmark with the applicable Unadjusted Benchmark Replacement by the Relevant Governmental Body or (b) any evolving or then-prevailing market convention for determining a spread adjustment, or method for calculating or determining such spread adjustment, for the replacement of such Benchmark with the applicable Unadjusted Benchmark Replacement for Dollar-denominated syndicated credit facilities at such time.

“Benchmark Replacement Date” means a date and time determined by the Calculation Agent, which date shall be no later than the earliest to occur of the following events with respect to the then-current Benchmark:

(a) in the case of clause (a) or (b) of the definition of “Benchmark Transition Event,” the later of (i) the date of the public statement or publication of information referenced therein and (ii) the date on which the administrator of such Benchmark (or the published component used in the calculation thereof) permanently or indefinitely ceases to provide all Available Tenors of such Benchmark (or such component thereof); or

A-7

(b) in the case of clause (c) of the definition of “Benchmark Transition Event,” the first date on which such Benchmark (or the published component used in the calculation thereof) has been determined and announced by the regulatory supervisor for the administrator of such Benchmark (or such component thereof) to be non-representative; provided that such non-representativeness will be determined by reference to the most recent statement or publication referenced in such clause (c) and even if any Available Tenor of such Benchmark (or such component thereof) continues to be provided on such date.

The “Benchmark Replacement Date” will be deemed to have occurred in the case of clause (a) or (b) with respect to any Benchmark upon the occurrence of the applicable event or events set forth therein with respect to all then-current Available Tenors of such Benchmark (or the published component used in the calculation thereof).

“Benchmark Transition Event” means the occurrence of one or more of the following events with respect to the then-current Benchmark:

(a) a public statement or publication of information by or on behalf of the administrator of such Benchmark (or the published component used in the calculation thereof) announcing that such administrator has ceased or will cease to provide all Available Tenors of such Benchmark (or such component thereof), permanently or indefinitely; provided that, at the time of such statement or publication, there is no successor administrator that will continue to provide any Available Tenor of such Benchmark (or such component thereof);

(b) a public statement or publication of information by the regulatory supervisor for the administrator of such Benchmark (or the published component used in the calculation thereof), the Board, the Federal Reserve Bank of New York, an insolvency official with jurisdiction over the administrator for such Benchmark (or such component), a resolution authority with jurisdiction over the administrator for such Benchmark (or such component) or a court or an entity with similar insolvency or resolution authority over the administrator for such Benchmark (or such component), which states that the administrator of such Benchmark (or such component) has ceased or will cease to provide all Available Tenors of such Benchmark (or such component thereof) permanently or indefinitely; provided that, at the time of such statement or publication, there is no successor administrator that will continue to provide any Available Tenor of such Benchmark (or such component thereof); or

(c) a public statement or publication of information by the regulatory supervisor for the administrator of such Benchmark (or the published component used in the calculation thereof) announcing that all Available Tenors of such Benchmark (or such component thereof) are not, or as of a specified future date will not be, representative.

A Benchmark Transition Event will be deemed to have occurred with respect to any Benchmark if a public statement or publication of information set forth above has occurred with respect to each then-current Available Tenor of such Benchmark (or the published component used in the calculation thereof).
