Compensation of Directors of Curis, Inc.

 Exhibit 10.15 
 Compensation of Directors of Curis, Inc. 
 As of March 30, 2006, cash compensation for
non-employee directors of Curis, Inc. was set at the following amounts: $15,000 as an annual retainer; $1,500 for each board meeting attended in person; and $750 for each telephonic board meeting. Non-employee directors who are members of a
committee of the board of directors receive cash compensation in the amount of $1,500 for each committee meeting attended in person on a day other than a day on which a board meeting is held and $750 for each telephonic committee meeting. In
addition, each non-employee director who is a chairman of a committee of the board receives an annual retainer of $5,000. 
 The chairman of
the board of directors of Curis, Inc. receives, as compensation for his service as a director, $10,000 per month plus a payment for his annual health insurance expense, which equaled $18,566 for the fiscal year ended December 31, 2005.
Non-employee directors are reimbursed for reasonable out-of-pocket expenses incurred in attending any board or committee meetings. 
 Directors who are employees of Curis, Inc. are not compensated for their attendance at board or committee meetings. 
 Pursuant to
the 2000 Director Stock Option Plan of Curis, Inc., each non-employee director receives options to purchase 25,000 shares of the common stock of Curis, Inc. on the date of his or her initial election to the board of directors. These option grants
vest ratably over four years on (a) the first anniversary of the date of grant and (b) the day before the annual meeting of stockholders each year thereafter. No further vesting occurs with respect to an option granted after the optionee
ceases to be a non-employee director. In addition, each non-employee director, other than a director who was initially elected to the board at any such annual meeting or, if previously, at any time after the prior year’s annual meeting,
receives options to purchase 5,000 shares of common stock on the date of each annual meeting of stockholders, provided that such director continues to serve as a director immediately after such annual meeting. The options granted annually are fully
vested on the date of grant. The exercise price of options granted under the plan equals the closing price of the common stock on the date of grant as reported on the Nasdaq National Market, or such other nationally recognized exchange or trading
system if the common stock is no longer traded on the Nasdaq National Market. Immediately prior to the occurrence of an acquisition event, as defined in the 2000 Director Stock Option Plan, each outstanding option granted under the plan becomes
fully vested. Options granted under the plan terminate, and may no longer be exercised, on the earlier of (i) the date ten years after the grant date of such option or (ii) the first anniversary of the date on which the optionee ceases to
serve as a director; provided, however, that in the event that a non-employee director has served as a director for at least five years, each option held by such director terminates, and may no longer be exercised, on the date ten years after the
grant date of the applicable option. 
 In addition to the above, each of the directors is eligible to receive stock options and stock awards
under the 2000 Stock Incentive Plan of Curis, Inc.Indenture dated as of June 21, 2005

wire transfer instructions to the Company, the Company shall pay all principal of, and premium, if any, interest and Additional Interest, if any, on, that Holder’s Notes in accordance with those instructions. All other payments on Notes shall

“Paying Agent” includes any additional paying agent. The Company may change any Paying Agent or Registrar without prior notice to any Holder. The Company shall notify the Trustee in writing of the name and address of any Agent not a party
to this Indenture. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Company or any of its Subsidiaries may act as Paying Agent or Registrar.

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

 41 

 (iii) The Registrar shall not be required to register the transfer of or exchange any Note selected for
redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part. 
  
 (iv) All Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes shall be the valid and

transfer of or to exchange any Notes during a period beginning at the opening of business 15 days before the day of any selection of Notes for redemption under Section 3.02 and ending at the close of business on the day of selection,

receipt of an Authentication Order, shall authenticate a replacement Note if the Trustee’s and the Company’s requirements are met. If required by the Trustee or the Company, an indemnity bond must be supplied by the Holder that is

Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section as not
outstanding. Except as set forth in Section 2.10, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note; however, Notes held by the Company or a Subsidiary of the Company shall not be deemed
to be outstanding for purposes of Section 3.07(a) or 3.08. 
  
 (b) If a Note is replaced pursuant to Section 2.08, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser or protected purchaser.

consent, Notes owned by the Company, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company, shall be considered as though not outstanding, except that for the purposes of
determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes that the Trustee knows are so owned shall be so disregarded. 
  
 Section 2.11. Temporary Notes. 
  
 (a) Until certificates representing Notes are ready for delivery, the Company may prepare and the Trustee, upon receipt of
an Authentication Order, shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of Definitive Notes but may have variations that the Company considers appropriate for temporary Notes and as shall be reasonably

defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Company shall fix or cause to be fixed each such special record date and payment date, provided that no such special record date shall 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) shall mail
or cause to be mailed to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid. 
  
 Section 2.14. CUSIP Numbers. 
  
 The Company in issuing the Notes may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers

and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company shall promptly notify the Trustee of any change in
the “CUSIP” numbers.

Holder thereof upon cancellation of the original Note. Notes called for redemption become due on the date fixed for redemption. On and after the redemption date, interest ceases to accrue on Notes or portions of them called for redemption.

  
 Section 3.03. Notice of Redemption.

  
 (a) At least 30 days but not more than 60 days before a
redemption date, the Company shall mail or cause to be mailed, by first class mail, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior

however, that the Company shall have delivered to the Trustee, at least 45 days prior to the redemption date, an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such
notice as provided in the preceding paragraph. The notice, if mailed in the manner provided herein shall be presumed to have been given, whether or not the Holder receives such notice. 
  
 Section 3.04. Effect of Notice of Redemption. 
  
 Once notice of redemption is mailed in accordance with Section 3.03,
Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price. Interest, if any, on Notes called for redemption ceases to accrue on and after the redemption date, unless the Company defaults in making
the applicable redemption payment. A notice of redemption may not be conditional. Any defect in or failure to give notice prescribed by this paragraph shall not affect the validity of the proceedings for the redemption of any note.

shall promptly return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption price of, and accrued and unpaid interest on, all Notes to be redeemed. 

 
 (b) If the Company complies with the provisions of Section 3.05(a),
on and after the redemption date, interest shall cease to accrue on the Notes or the portions of Notes called for redemption. If a Note is redeemed on or after an interest record date but on or prior to the related interest payment date, then any
accrued and unpaid interest 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 shall not be so paid upon surrender for redemption 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 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.

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 respective Holder thereof. The Company shall publicly announce the

September 10, 2005 and the Company shall include in its report on Form 10-Q with respect to the fiscal quarter ended June 30, 2005, to the extent not already required to be included, all information required under Items 1.03, 2.01, 2.03,
2.04, 2.05, 2.06, 4.01, 4.02, 5.02 and 5.03 of Form 8-K to be included in any current report on Form 8-K that would otherwise be required to be provided pursuant to the Commission’s rules and regulations by a date prior to September 10,
2005); and 
  
 (b) all current reports that would
be required to be filed with the Commission on Form 8-K if the Company were required to file such reports (provided, however, that the obligation to furnish to the Trustee any such current report shall commence on and as of
September 10, 2005). 
  
 After consummation of the Exchange
Offer contemplated by the Registration Rights Agreement, whether or not required by the Commission, the Company will comply with the periodic reporting requirements of the Exchange Act and will file the reports specified in the preceding paragraph
with the Commission within the time periods specified above unless the Commission will not accept such a filing. The Company shall not take any action for the purpose of causing the Commission not to accept any such filings. If, notwithstanding the
foregoing, the Commission will not accept the Company’s filings for any reason, the Company will post the reports referred to in the preceding paragraph on its website within the time periods that would apply if the Company were required to
file those reports with the Commission. 
  
 If the Company has
designated any of its Subsidiaries as Unrestricted Subsidiaries, then the quarterly and annual financial information required by this covenant will include a reasonably detailed presentation, either on the face of the financial statements or in the
footnotes thereto and in “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” of the financial condition and results of operations of the Company and its Restricted Subsidiaries separate from the
financial condition and results of operations of the Unrestricted Subsidiaries of the Company. 
  
 Notwithstanding the foregoing, so long as Holdings is a Guarantor, the reports, information and other documents required to be filed and provided as described above will be those of Holdings, rather than those of the
Company, provided, however, that financial information with respect to the Company satisfying the requirements described above are included in such reports, information and other documents of Holdings and such reports, information and
other documents of Holdings would satisfy the Commission’s requirements in lieu of the Company’s reports, information and other documents. 
  

 51 

 In addition, the Company and the Guarantors shall, for so long as any Notes remain outstanding, furnish
to the Holders and to prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act. 
  
 Section 4.04. Compliance Certificate. 
  
 (a) The Company shall deliver to the Trustee, within 120 days after the end of each fiscal year, an Officers’

Company has kept, observed, performed and fulfilled its obligations under this Indenture, the Collateral Documents and the Intercreditor Agreement, and further stating, as to each such Officer signing such certificate, that to his or her knowledge,
the Company has kept, observed, performed and fulfilled its obligations under this Indenture, the Collateral Documents and the Intercreditor Agreement and is not in default in the performance or observance of any of the terms, provisions and
conditions of this Indenture, the Collateral Documents or the Intercreditor Agreement (or, if a Default or Event of Default shall have occurred, describing all such Defaults or Events of Default of which he or she may have knowledge and what action
the Company is taking or proposes to take with respect thereto) and that to his or her knowledge no event has occurred and remains in existence by reason of which payments on account of the principal of or interest on the Notes is prohibited or if
such event has occurred, a description of the event and what action the Company is taking or proposes to take with respect thereto. 
  
 (b) The Company shall, so long as any of the Notes are outstanding, deliver to the Trustee, within five Business Days after any Officer becomes aware of
any Default or Event of Default, an Officers’ Certificate specifying such Default or Event of Default and what action the Company is taking or proposes to take with respect thereto. 
  
 Section 4.05. Taxes. 
  
 The Company shall pay, and shall cause each of its Subsidiaries to pay, prior to delinquency, any taxes, assessments, and
governmental levies except such as are contested in good faith and by appropriate proceedings or where the failure to effect such payment is not adverse in any material respect to the Holders of the Notes. 
  
 Section 4.06. Stay, Extension and Usury Laws.

  
 The Company agrees (to the extent that it may lawfully do so)
that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the
performance of this Indenture; and the Company hereby expressly waives all benefit or advantage of any such law, and covenants that it shall not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the
Trustee, but shall suffer and permit the execution of every such power as though no such law has been enacted.

Subsidiaries to, directly or indirectly: 
  
 (i)
declare or pay (without duplication) any dividend or make any other payment or distribution on account of the Company’s or any of its Restricted Subsidiaries’ Equity Interests (including, without limitation, any payment in connection with
any merger or consolidation involving the Company or any of its Restricted Subsidiaries) or to the direct or indirect holders of the Company’s or any of its Restricted Subsidiaries’ Equity Interests in their capacity as such (other than

anticipation of satisfying a sinking fund obligation, principal installment or final maturity, in each case, due within one year of the date of such purchase, repurchase or other acquisition; or 
  
 (iv) make any Restricted Investment (all such payments and
other actions set forth in clauses (i) through (iv) above being collectively referred to as “Restricted Payments”), 
  
 unless, at the time of and after giving effect to such Restricted Payment: 
  
 (1) no Default or Event of Default shall have occurred and be continuing or would occur as a consequence
thereof; 
  
 (2) the Company would, at the time

 (3) such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by the Company and its Restricted Subsidiaries after the Issue Date (excluding Restricted Payments permitted by

 53 

 
(ix), (x), (xi), (xv) and (xvi) of clause (b) of this Section 4.07), is less than the sum, without duplication, of:

 (C) with respect to Restricted Investments made by the Company and its Restricted Subsidiaries after the Issue Date, an amount equal to
the net reduction in such Restricted Investments in any Person resulting from repayments of loans or advances, dividends or other distributions, or other transfers of assets, in each case, to the Company or any Restricted Subsidiary or from the net
cash proceeds from the sale of any such Restricted Investment (except, in each case, to the extent any such payment or proceeds are included in the calculation of Consolidated Net Income), from the release of any Guarantee (except to the extent any
amounts are paid under such Guarantee) or from redesignations of Unrestricted Subsidiaries as Restricted Subsidiaries, not to exceed, in each case, the amount of Restricted Investments previously made by the Company or any Restricted Subsidiary in
such Person or Unrestricted Subsidiary after the Issue Date. 
  
 (b) The provisions of Section 4.07(a) shall not prohibit, so long as, in the case of clauses (vi), (vii), (xii), (xiii), (xiv), (xv) and (xvi) of this clause (b), no Default has occurred and is continuing or would
be caused thereby: 
  
 (i) the payment of any
dividend within 60 days after the date of declaration thereof, if at said date of declaration such payment would have complied with the provisions of this Indenture;

substantially concurrent sale (other than to a Subsidiary of the Company) of, Equity Interests (other than Disqualified Stock) of the Company; provided that the amount of any such net cash proceeds that are utilized for any such redemption,

acquisition or exchange shall be excluded from clause (3)(B) of clause (a) of this Section 4.07;

Company to any Parent in amounts required to pay the tax obligations of such Parent attributable to the Company and its Subsidiaries determined as if the Company and its Subsidiaries had filed a separate consolidated, combined or unitary return for
the relevant taxing jurisdiction; provided, however, that, to the extent that the computation of tax obligations attributable to the Company and its Subsidiaries takes into account any tax refund or tax reduction which would be a
Company Tax Benefit, the amount of such dividend or 

  

 55 

 
distributions shall include an amount equal to such tax refund or reduction, and provided further that (x) any refunds received by any Parent
attributable to the Company or any of its Subsidiaries shall promptly be returned by such Parent to the Company through a contribution to the common equity of, or the purchase of common stock (other than Disqualified Stock) of the Company from, the

distributions shall be made no earlier than ten days prior to the required date of payment of the relevant interest installment or AHYDO Mandatory Redemption Amount, as applicable and provided further that, to the extent that Holdings shall
be required, pursuant to the terms of the indenture governing the Senior Discount Notes (as in effect on the Issue Date), to provide to the trustee under such indenture an officer’s certificate (in connection with such mandatory redemption) as
to the amount of the AHYDO Mandatory Redemption Amount, the Company shall, prior to making such payment of dividends or other distributions under clause (y), deliver to the Trustee an Opinion of Counsel to the same effect as the statements
contained in such officers’ certificate; and 
  
 (xvi) other Restricted Payments in an aggregate amount not to exceed $7.5 million. 
  
 (c) The amount of all Restricted Payments (other than cash) shall be the Fair Market Value on the date of the Restricted Payment of the asset(s) or

Subsidiary to: 
  
 (i) pay dividends or make any

Credit Agreement, Existing Indebtedness or any other agreements in effect on the Issue Date and any amendments, modifications, restatements, renewals, extensions, supplements, refundings, 

  

 57 

 
replacements or refinancings thereof, provided that the encumbrances and restrictions in any such amendments, modifications, restatements, renewals,
extensions, supplements, refundings, replacement or refinancings are not materially more restrictive, taken as a whole, than those contained in the Credit Agreement, Existing Indebtedness or such other agreements, as the case may be, as in effect on
the Issue Date; 
  
 (ii) set forth in this
Indenture, the Notes, the Exchange Notes, the related Note Guarantees and the Collateral Documents;

other than the Person, or the property or assets of the Person, so acquired and any amendments, modifications, restatements, renewals, extensions, supplements, refundings, replacements or refinancings thereof, provided that the encumbrances
and restrictions in any such amendments, modifications, restatements, renewals, extensions, supplements, refundings, replacement or refinancings are not materially more restrictive, taken as a whole, than those in effect on the date of the
acquisition; 
  
 (v) in the case of clause
(iii) of Section 4.08(a): 
  
 (x) that
restrict in a customary manner the subletting, assignment or transfer of any property or asset that is a lease, license, conveyance or contract or similar property or asset,

 (vi) existing under, by reason of or with respect to any agreement for the sale or other disposition of all
or substantially all of the Capital Stock of, or property and assets of, a Restricted Subsidiary that restrict distributions by, or the transfer of Capital Stock of, that Restricted Subsidiary pending such sale or other disposition;

(x) such encumbrances or restrictions are ordinary and customary with respect to the type of Indebtedness being Incurred and (y) such encumbrances or restrictions shall not affect the Company’s ability to make payments of principal or
interest on the Notes, as determined in good faith by the Board of Directors of the Company. 
  
 Section 4.09. Incurrence of Indebtedness. 
  
 (a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, Incur any
Indebtedness; provided, however, that the Company or any Subsidiary Guarantor may Incur Indebtedness if the Fixed Charge Coverage Ratio of the Company for its most recently ended four full fiscal quarters for which internal financial
statements are available immediately preceding the date on which such additional Indebtedness is Incurred would have been at least 2.0:1, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the
additional Indebtedness had been Incurred at the beginning of such four-quarter period. 
  
 (b) Clause (a) of this Section 4.09 shall not prohibit the Incurrence of any of the following items of Indebtedness (collectively, “Permitted Debt”): 
  
 (i) the Incurrence by the Company or any Subsidiary
Guarantor of Indebtedness under Credit Facilities (including, without limitation, the Incurrence by the Subsidiary Guarantors of Guarantees thereof) in an aggregate amount at any one time outstanding pursuant to this clause (i) not to exceed
$50.0 million, less the aggregate amount of all Net Proceeds of Asset Sales applied by the Company or any Restricted Subsidiary thereof to permanently repay any such Indebtedness pursuant to Section 4.10; 
  
 (ii) the Incurrence of Existing Indebtedness; 
  
 (iii) the Incurrence by the Company and the Subsidiary
Guarantors of Indebtedness represented by the Notes to be issued on the Issue Date and Exchange Notes issued therefor pursuant to the Registration Rights Agreement and the related Note Guarantees; 
  

 59

Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to refund, refinance or replace Indebtedness (other than intercompany Indebtedness) that was permitted by this Indenture to be Incurred under clause
(a) of this Section 4.09 or clause (ii), (iii), (iv), or (xii) of this Section 4.09(b); 
  
 (v) the Incurrence by the Company or any of its Restricted Subsidiaries of intercompany Indebtedness owing to and held by the Company or
any of its Restricted Subsidiaries; provided, however, that: 
  
 (x) if the Company or any Subsidiary Guarantor is the obligor on such Indebtedness, such Indebtedness must be unsecured and expressly subordinated in right of payment to all Obligations with respect to the Notes, in
the case of the Company, or the Note Guarantee, in the case of a Subsidiary Guarantor; 
  
 (y) Indebtedness owed to the Company or any Subsidiary Guarantor must be evidenced by an unsubordinated promissory note, unless the
obligor under such Indebtedness is the Company or a Guarantor; and 
  
 (z) (i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary thereof and (ii) any sale or
other transfer of any such Indebtedness to a Person that is not either the Company or a Restricted Subsidiary thereof, shall be deemed, in each case, to constitute an Incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as
the case may be, that was not permitted by this clause (v); 
  
 (vi) the Guarantee by the Company or any of the Subsidiary Guarantors of Indebtedness of the Company or a Restricted Subsidiary of the Company that was permitted to be Incurred by another provision of this
Section 4.09; 
  
 (vii) the Incurrence by
the Company or any of its Restricted Subsidiaries of Hedging Obligations that are Incurred for the purpose of fixing, hedging or swapping interest rate, commodity price or foreign currency exchange rate risk (or to reverse or amend any such
agreements previously made for such purposes), and not for speculative purposes, and that do not increase the Indebtedness of the obligor outstanding at any time other than as a result of fluctuations in interest rates, commodity prices or foreign
currency exchange rates or by reason of fees, indemnities and compensation payable thereunder; 
  
 (viii) the Incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness arising from agreements providing for
indemnification, adjustment of purchase price or similar obligations, or Guarantees or letters of credit, surety bonds or performance bonds securing any obligations of the Company or any of its Restricted Subsidiaries pursuant to such agreements, in
any case, Incurred in connection with the disposition of any business, assets or Restricted Subsidiary (other than Guarantees of Indebtedness Incurred by any Person acquiring all or any portion of such business, assets 

  

 60 

 
or Restricted Subsidiary for the purpose of financing such acquisition), so long as the amount does not exceed the gross proceeds actually received by the
Company or any Restricted Subsidiary thereof in connection with such disposition; 
  
 (ix) the Incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness arising from the honoring by a bank or other
financial institution of a check, draft or similar instrument drawn against insufficient funds in the ordinary course of business, provided, however, that such Indebtedness is extinguished within five Business Days of its Incurrence;

  
 (x) the Incurrence by the Company or any of
its Restricted Subsidiaries of Indebtedness constituting reimbursement obligations with respect to letters of credit in respect of workers’ compensation claims or self-insurance obligations or bid, performance or surety bonds (in each case
other than for an obligation for borrowed money); 
  
 (xi) the Incurrence by the Company of Indebtedness to the extent that the net proceeds thereof are promptly deposited to defease or to satisfy and discharge the Notes; or 
  
 (xii) the Incurrence by the Company or any Restricted Subsidiary of additional Indebtedness (which may
include Indebtedness Incurred under Credit Facilities after the Issue Date) in an aggregate amount at any time outstanding, including all Permitted Refinancing Indebtedness Incurred to refund, refinance or replace any Indebtedness Incurred pursuant
to this clause (xii), not to exceed $30.0 million. 
  
 (c) For
purposes of determining compliance with this Section 4.09, in the event that any proposed Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in clauses (i) through (xii) of
Section 4.09(b), or is entitled to be Incurred pursuant to Section 4.09(a), the Company shall be permitted to classify such item of Indebtedness at the time of its Incurrence in any manner that complies with this Section 4.09. In
addition, any Indebtedness originally classified as Incurred pursuant to clauses (i) through (xii) of Section 4.09(b) may later be reclassified by the Company such that it shall be deemed as having been Incurred pursuant to another of
such clauses to the extent that such reclassified Indebtedness could be Incurred pursuant to such new clause at the time of such reclassification. Notwithstanding the foregoing, Indebtedness under the Credit Agreement outstanding on the Issue Date
shall be deemed to have been Incurred on such date in reliance on the exception provided by clause (i) of the definition of Permitted Debt. 
  
 (d) Notwithstanding any other provision of this Section 4.09, the maximum amount of Indebtedness that may be Incurred pursuant to this
Section 4.09 shall not be deemed to be exceeded with respect to any outstanding Indebtedness due solely to the result of fluctuations in the exchange rates of currencies. 
  
 (e) The Company shall not Incur any Indebtedness that is subordinate in right of payment to any other Indebtedness of the
Company unless it is subordinate in right of payment to the Notes to the same extent. The Company will not permit any Subsidiary 

  

 61 

 
Guarantor to Incur any Indebtedness that is subordinate in right of payment to any other Indebtedness of such Subsidiary Guarantor unless it is subordinate
in right of payment to such Subsidiary Guarantor’s Note Guarantee to the same extent For purposes of the foregoing, no Indebtedness shall be deemed to be subordinated in right of payment to any other Indebtedness of the Company or any
Subsidiary Guarantor, as applicable, solely by reason of any Liens or Guarantees arising or created in respect thereof or by virtue of the fact that the holders of any secured Indebtedness have entered into intercreditor agreements giving one or
more of such holders priority over the other holders in the collateral held by them. 
  
 Section 4.10. Asset Sales. 
  
 (a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless: 
  
 (i) the Company (or the Restricted Subsidiary, as the case
may be) receives consideration at the time of such Asset Sale at least equal to the Fair Market Value of the assets or Equity Interests issued or sold or otherwise disposed of; and 
  
 (ii) at least 75% of the consideration therefor received by the Company or such Restricted Subsidiary is in
the form of cash, Cash Equivalents or Replacement Assets or a combination of both. For purposes of this provision, each of the following shall be deemed to be cash: 
  
 (x) any liabilities (as shown on the Company’s or such Restricted Subsidiary’s most recent balance
sheet) of the Company or any Restricted Subsidiary (other than contingent liabilities, Indebtedness that is by its terms subordinated to the Notes or any Note Guarantee and liabilities to the extent owed to the Company or any Affiliate of the
Company) that are assumed by the transferee of any such assets or Equity Interests pursuant to a written novation agreement that releases the Company or such Restricted Subsidiary from further liability therefor; 
  
 (y) any securities, notes or other obligations received by
the Company or any such Restricted Subsidiary from such transferee that are (within 90 days of receipt and subject to ordinary settlement periods) converted by the Company or such Restricted Subsidiary into cash (to the extent of the cash received
in that conversion); and 
  
 (z) any Designated
Non-Cash Consideration received by the Company or any such Restricted Subsidiary in the Asset Sale having an aggregate Fair Market Value, as determined by the Board of Directors of the Company, taken together with all other Designated Non-Cash
Consideration received pursuant to this clause that is at that time outstanding, not to exceed $5.0 million. 
  

 62 

 (b) Within 360 days after the receipt of any Net Proceeds from an Asset Sale, the Company or any of its
Restricted Subsidiaries may apply, or cause to be applied, such Net Proceeds at its option: 
  
 (i) to permanently reduce Indebtedness outstanding under the Credit Agreement (and to permanently reduce commitments with respect thereto,
in the case of revolving borrowings); or 
  
 (ii)
to purchase Replacement Assets (or enter into a binding agreement to purchase such Replacement Assets; provided that (x) such purchase is consummated within 180 days after the date of such binding agreement and (y) if such purchase
is not consummated within the period set forth in subclause (x) and at least 360 days shall have elapsed since receipt of the Net Proceeds not so applied, such Net Proceeds shall be deemed to be Excess Proceeds (as defined below)). 

 
 Pending the final application of any such Net Proceeds, the Company may temporarily
reduce, or cause to be reduced, revolving credit borrowings or otherwise invest such Net Proceeds in any manner that is not prohibited by this Indenture. 
  
 (c) On the 361st day after an Asset Sale (or such later date immediately following the expiry of the 180-day period without the consummation of a purchase
of Replacement Assets pursuant to clause (ii) of Section 4.10(b)) or such earlier date, if any, as the Company or its Restricted Subsidiaries determines not to apply the Net Proceeds relating to such Asset Sale as set forth in
Section 4.10(b) (each such date being referred as an “Excess Proceeds Trigger Date”), such aggregate amount of Net Proceeds that has not been applied on or before the Excess Proceeds Trigger Date as permitted in the preceding
paragraph (“Excess Proceeds”) shall be applied by the Company to make an offer (an “Asset Sale Offer”) to all Holders of Notes and to all holders of Pari Passu Debt to purchase the maximum principal amount of Notes
and Pari Passu Debt that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer shall be equal to 100% of the principal amount of the Notes and Pari Passu Debt repurchased plus accrued and unpaid interest and Additional
Interest, if any, to the date of purchase, and shall be payable in cash. 
  
 The Company may defer the Asset Sale Offer until there are aggregate unutilized Excess Proceeds equal to or in excess of $10.0 million resulting from one or more Asset Sales, at which time the entire unutilized amount
of Excess Proceeds (not only the amount in excess of $10.0 million) shall be applied as provided in the preceding paragraph. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use such Excess Proceeds for any
purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of the Notes and Pari Passu Debt tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Notes and Pari Passu Debt shall be purchased on a
pro rata basis based on the principal amount of Notes and Pari Passu Debt tendered. Upon completion of each Asset Sale Offer, the Excess Proceeds subject to such Asset Sale shall no longer be deemed to be Excess Proceeds.

 63 

 
renew or extend any transaction, contract, agreement, understanding, loan, advance or Guarantee with, or for the benefit of, any Affiliate (each, an
“Affiliate Transaction”), unless: 
  
 (i) such Affiliate Transaction is on terms that are no less favorable to the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable arm’s-length transaction by the Company or such
Restricted Subsidiary with a Person that is not an Affiliate of the Company or any of its Restricted Subsidiaries; and 
  
 (ii) the Company delivers to the Trustee: 
  
 (x) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of
$5.0 million, a Board Resolution set forth in an Officers’ Certificate certifying that such Affiliate Transaction or series of related Affiliate Transactions complies with this covenant and that such Affiliate Transaction or series of related
Affiliate Transactions has been approved by a majority of the disinterested members of the Board of Directors of the Company; and 
  
 (y) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of
$10.0 million, an opinion as to the fairness to the Company or such Restricted Subsidiary of such Affiliate Transaction or series of related Affiliate Transactions from a financial point of view issued by an independent accounting, appraisal or
investment banking firm of national standing. 
  
 (b) The
following items shall not be deemed to be Affiliate Transactions and, therefore, shall not be subject to the provisions of clause (a) of this Section 4.11: 
  
 (i) transactions between or among the Company and/or its Restricted Subsidiaries; 
  
 (ii) payment of reasonable and customary fees to, and

Subsidiaries than the original agreement or arrangement in existence on the Issue Date; 
  

 64 

 (vi) any employment, consulting, service or termination agreement, or reasonable and
customary indemnification arrangements, entered into by the Company or any of its Restricted Subsidiaries with officers and employees of the Company or any of its Restricted Subsidiaries and the payment of compensation to officers and employees of
the Company or any of its Restricted Subsidiaries (including amounts paid pursuant to employee benefit plans, employee stock option or similar plans), so long as such agreement or payment has been approved by a majority of the disinterested members
of the Board of Directors of the Company; and 
  
 (vii) Permitted Investments.

required to offer payment (a “Change of Control Payment”) in cash equal to 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest and Additional Interest, if any, thereon, to the date of
repurchase (the “Change of Control Payment Date,” which date shall be no earlier than the date of such Change of Control). No later than 30 days following any Change of Control, the Company shall mail a notice to each Holder
describing the transaction or transactions that constitute the Change of Control and offering to repurchase Notes on the Change of Control Payment Date specified in such notice, which date shall be no earlier than 30 days and no later than 60 days
from the date such notice is mailed, pursuant to the procedures required by Section 3.08 and this Section 4.14 and described in such notice.

 (c) deliver or cause to be delivered to the Trustee the Notes so accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions thereof being purchased by the Company.

  
 The Paying Agent shall promptly mail or wire transfer to each
Holder of Notes so tendered the Change of Control Payment for such Notes, and the Trustee shall promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion
of the Notes surrendered, if any; provided that each such new Note shall be in a principal amount of $1,000 or an integral multiple thereof. 
  
 The Company shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

  
 The provisions described above that require the Company to
make a Change of Control Offer following a Change of Control shall be applicable regardless of whether any other provisions of this Indenture are applicable. 
  
 The Company shall not be required to make a Change of Control Offer upon a Change of Control if (a) a third party makes the Change of Control Offer
in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.14 and Section 3.08 and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer or (b) notice
of redemption of all of the outstanding Notes has been given pursuant to Section 3.07, unless and until there is a Default in payment of the applicable redemption price.

Subsidiary of the Company to be an Unrestricted Subsidiary; provided that: 
  
 (i) any Guarantee by the Company or any Restricted Subsidiary thereof of any Indebtedness of the Subsidiary being so designated shall be

 (ii) the aggregate Fair Market Value of all outstanding
Investments owned by the Company and its Restricted Subsidiaries in the Subsidiary being so designated (including any Guarantee by the Company or any Restricted Subsidiary thereof of any Indebtedness of such Subsidiary) shall be deemed to be a

 (iii) such Subsidiary does not hold any Liens on any property of the Company or any Restricted Subsidiary thereof; 
  

 66 

 (iv) the Subsidiary being so designated: 
  
 (w) is not party to any agreement, contract, arrangement or
understanding with the Company or any Restricted Subsidiary of the Company unless the terms of any such agreement, contract, arrangement or understanding are no less favorable to the Company or such Restricted Subsidiary than those that might be

or (ii) fails to meet the requirement described in subclause (z) of clause (iv) of Section 4.15(a) and such failure continues for a period of 30 days, it shall thereafter cease to be an Unrestricted Subsidiary for purposes of
this Indenture and any Indebtedness, Investments, or Liens on the property, of such Subsidiary shall be deemed to be Incurred or made by a Restricted Subsidiary of the Company as of such date and, if such Indebtedness, Investments or Liens are not
permitted to be Incurred or made as of such date under this Indenture, the Company shall be in default under this Indenture. 
  
 (c) The Board of Directors of the Company may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary; provided that:

Incurrence of Indebtedness by a Restricted Subsidiary of the Company of any outstanding Indebtedness of such 

  

 67 

 
Unrestricted Subsidiary and such designation shall only be permitted if such Indebtedness is permitted under Section 4.09; 
  
 (ii) all outstanding Investments owned by such Unrestricted
Subsidiary shall be deemed to be made as of the time of such designation and such designation shall only be permitted if such Investments would be permitted under Section 4.07;

a Domestic Subsidiary on or after the Issue Date, then that newly acquired or created Domestic Subsidiary must become a Subsidiary Guarantor, execute a supplemental indenture (substantially in the form of Exhibit D), grant a valid and
perfected security interest (subject to the terms of the Intercreditor Agreement) to the Trustee and the Holders of Notes in all of its property and assets constituting Collateral securing its obligations under its Guarantee and deliver Opinions of
Counsel to the Trustee (in form and substance satisfactory to the Trustee) as to such Guarantee and such security interest. 
  
 (b) The Company shall not permit any of its Restricted Subsidiaries, directly or indirectly, to Guarantee or pledge any assets to secure the payment of

with such Subsidiary’s Guarantee of such other Indebtedness, (ii) grants a valid and perfected security interest (subject to the terms of the Intercreditor Agreement) to the Trustee and the Holders of Notes in all of its property and
assets constituting Collateral securing its obligations under such Guarantee, and (iii) delivers to the Trustee Opinions of Counsel (in form and substance satisfactory to the Trustee) as to such Guarantee and such security interest.

successor Person constituting Collateral securing its obligations under such Note Guarantee, and (iii) delivery to the Trustee of Opinions of Counsel (in form and substance satisfactory to the Trustee) as to such Guarantee and such security
interest, such successor Person shall succeed to and be substituted for a Subsidiary Guarantor with the same effect as if it had been named herein as a Subsidiary Guarantor. Such successor Person thereupon may cause to be signed any or all of the
Note Guarantees to be endorsed upon all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee. All the Note Guarantees so issued shall in all respects have the same legal rank and
benefit under this Indenture as the Note Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all of such Note Guarantees had been issued at the date of the execution hereof.

 (i) in connection with any sale or other
disposition of all of the Capital Stock of such Subsidiary Guarantor to a Person that is not (either before or after giving effect to such transaction) a Restricted Subsidiary of the Company, if the sale of all such Capital Stock of that Subsidiary
Guarantor complies with Section 4.10; 
  
 (ii) if the Company properly designates the Restricted Subsidiary that is a Subsidiary Guarantor as an Unrestricted Subsidiary under this Indenture; or 
  

 69 

 (iii) solely in the case of a Note Guarantee created pursuant to clause (b) of this

 The Company shall not, and shall not permit any of its
Restricted Subsidiaries to, enter into any Sale and Leaseback Transaction; provided that the Company or any Restricted Subsidiary may enter into a Sale and Leaseback Transaction if:

Section 4.12; 
  
 (b) the gross cash
proceeds of such Sale and Leaseback Transaction are at least equal to the Fair Market Value of the property that is the subject of such Sale and Leaseback Transaction; and 
  
 (c) the transfer of assets in such Sale and Leaseback Transaction is permitted by, and the Company applies
the proceeds of such transaction in compliance with, Section 4.10.

sales of Equity Interests of a Restricted Subsidiary of the Company by the Company or a Restricted Subsidiary thereof; provided that (a) the Company or such Restricted Subsidiary selling such Equity Interests complies with the provisions
of Section 4.10, (b) any sales of Preferred Stock of a Restricted Subsidiary that result in such Preferred Stock being held by a Person other than the Company or a Restricted Subsidiary thereof shall be deemed to be an Incurrence of
Indebtedness and must comply with the provisions of Section 4.09 and (c) if, immediately after giving effect to such issuance, transfer, conveyance, sale or other disposition, such Restricted Subsidiary would no longer constitute a
Restricted Subsidiary, any Investment in such Person remaining after giving effect to such issuance or sale would have been permitted to be made under Section 4.07 if made on the date of such issuance or sale.

(ii) appoints a custodian of the Company, any Guarantor or any Significant Subsidiary of the Company or for all or substantially all of
the property of the Company, any Guarantor or any Significant Subsidiary of the Company; or 
  
 (iii) orders the liquidation of the Company, any Guarantor or any Significant Subsidiary of the Company; 
  
 and the order or decree remains unstayed and in effect for 60 consecutive
days. 
  
 Holders of the Notes may not enforce this Indenture, the
Collateral Documents or the Notes except as provided in this Indenture, the Collateral Documents and the Intercreditor Agreement. Subject to certain limitations, Holders of a majority in aggregate principal amount of the then outstanding Notes may
direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any Default or Event of Default (except a Default or Event of Default relating to the payment of principal or interest or
Additional Interest) if it determines that withholding notice is in their interest. 
  
 Section 6.02. Acceleration. 
  
 In the case of an Event of Default under clause (i) or (j) of the definition of an Event of Default, all outstanding Notes shall become due and
payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes may declare all the Notes to be due and
payable immediately by notice in writing to the Company specifying the Event of Default. 
  
 In the case of any Event of Default occurring by reason of any willful action or inaction taken or not taken by or on behalf of the Company with the intention of avoiding payment of the premium that the Company would
have had to pay if the Company then had elected to redeem the Notes pursuant to Section 3.07, an equivalent premium shall also become and be immediately due and payable to the extent permitted by law upon the acceleration of the Notes. If an
Event of Default occurs prior to the first date on which the Company may redeem the Notes pursuant to Section 3.07, by reason of any willful action (or inaction) taken (or not taken) by or on behalf of the Company with the intention of avoiding
the prohibition on redemption of the Notes prior to such first date, then the premium specified in Section 3.07 shall also become immediately due and payable to the extent permitted by law upon the acceleration of the Notes. 
  

 74 

 Section 6.03. Other Remedies. 
  
 (a) If an Event of Default occurs and is continuing, the Trustee may pursue
any available remedy to collect the payment of principal of, and premium, if any, interest and Additional Interest, if any, on, the Notes or to enforce the performance of any provision of the Notes or this Indenture. 
  
 (b) The Trustee may maintain a proceeding even if it does not possess any of
the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver
of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law. 
  
 Section 6.04. Waiver of Past Defaults. 
  

The Holders of a majority in principal amount of the Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes
waive any existing Default or Event of Default and its consequences hereunder except a continuing Default or Event of Default in the payment of premium, if any, interest or Additional Interest, if any, on, or the principal of, the Notes,
provided, however, that the Holders of a majority in principal amount of the then outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration.

  
 The Company shall deliver to the Trustee an Officers’
Certificate stating that the requisite percentage of Holders have consented to such waiver and attaching copies of such consents. In case of any such waiver, the Company, the Trustee and the Holders shall be restored to their former positions and
rights hereunder and under the Notes, respectively. This Section 6.04 shall be in lieu of Section 316(a)(1)(B) of the TIA and such Section 316(a)(1)(B) of the TIA is hereby expressly excluded from this Indenture and the Notes, as
permitted by the TIA. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture, but no such waiver shall extend to any subsequent or
other Default or impair any right consequent thereon. 
  
 Section 6.05. Control by Majority. 
  
 The
Holders of a majority in principal amount of the then outstanding Notes shall have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee. However, the Trustee may refuse to
follow any direction that conflicts with law or this Indenture, that may involve the Trustee in personal liability or that the Trustee determines in good faith may be unduly prejudicial to the rights of Holders of Notes not joining in the giving of
such direction and may take any other action it deems proper that is not inconsistent with any direction received from Holders of Notes. The Trustee may withhold from Holders of the Notes notice of any Default or Event of Default (except a Default
or Event of Default relating to the payment of principal, premium, if any, interest or Additional Interest, if any) if it determines that withholding notice is in their interest. 
  

 75 

 Section 6.06. Limitation on Suits. 
  
 (a) A Holder may not pursue any remedy with respect to this Indenture or the Notes unless: 
  
 (i) the Holder gives the Trustee written notice of a
continuing Event of Default; 
  
 (ii) the Holders
of at least 25% in aggregate principal amount of outstanding Notes make a written request to the Trustee to pursue the remedy; 
  
 (iii) such Holder or Holders offer and, if requested, provide to the Trustee security and indemnity satisfactory to the Trustee against
any costs, liability or expense that might be incurred by it in connection with the request or direction; 
  
 (iv) the Trustee does not comply with the request within 60 days after receipt of the request and the offer of and, if requested, the
provision of indemnity; and 
  
 (v) during such
60-day period, the Holders of a majority in aggregate principal amount of the then outstanding Notes do not give the Trustee a direction that is inconsistent with the request. 
  
 (b) A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a
preference or priority over another Holder of a Note. 
  
 Section 6.07. Rights of Holders of Notes to Receive Payment. 
  
 Notwithstanding any other provision of this Indenture, the limitations set forth in Section 6.06 shall not apply to the right of any Holder of a Note to receive payment of the principal of, or premium, if any,
interest or Additional Interest, if any, on, such Note or to bring suit for the enforcement of any such payment, on or after the due date expressed in the Notes, which right shall not be impaired or affected without the consent of the Holder.

  
 Section 6.08. Collection Suit by
Trustee. 
  
 If an Event of Default specified in
Section 6.01(a) or (b) 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, interest and
Additional Interest, if any, remaining unpaid on the Notes and interest on overdue principal and premium, if any, and, to the extent lawful, interest and Additional Interest, 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. 
  
 Section 6.09. Trustee May File Proofs of Claim. 
  
 The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in
order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the 

  

 76 

 
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 securities or 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. 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 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. 
  
 (a) If the Trustee collects any money pursuant to this Article Six, it shall pay out the money in the following order: 
  
 First: to the Trustee, its agents and attorneys for amounts
due under Section 7.07, including payment of all compensation, expense and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 
  
 Second: to Holders of Notes for amounts due and unpaid on the Notes for principal, premium, if any, interest
and Additional Interest, if any, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any, interest and Additional Interest, if any, respectively; and 
  
 Third: to the Company or to such party as a court of
competent jurisdiction shall direct. 
  
 (b) The Trustee may fix a
record date and payment date for any payment to Holders of Notes pursuant to this Section 6.10. 
  
 Section 6.11. Undertaking for Costs. 
  
 In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a
Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees,
against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a 

  

 77 

 
suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than ten percent in principal amount of
the then outstanding Notes. 
  
 ARTICLE SEVEN

 Section 7.01. Duties of Trustee. 
  
 Except to the extent, if any, provided otherwise in the TIA (as from time to time in effect): 
  
 (a) If an Event of Default has occurred and is continuing,
the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in its exercise, as a prudent person would exercise or use under the circumstances in the conduct of such

 (ii) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the
Trustee and conforming to the requirements of this Indenture. However, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture. 
  
 (c) The Trustee may not be relieved from liabilities for its
own negligent action, its own negligent failure to act, or its own willful misconduct, except that: 
  
 (i) this paragraph does not limit the effect of paragraph (b) of this Section 7.01; 
  
 (ii) the Trustee shall not be liable for any error of
judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and 
  
 (iii) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction
received by it pursuant to Section 6.05.

 78 

 (e) No provision of this Indenture shall require the Trustee to expend or risk its own
funds or incur any liability. The Trustee shall be under no obligation to exercise any of its rights and powers under this Indenture at the request of any Holders, unless such Holder shall have offered to the Trustee security and indemnity
satisfactory to it against any loss, costs, liability or expense that might be incurred by it in connection with the request or direction. 
  
 (f) Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law.

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 shall not be responsible for the misconduct or negligence of any agent appointed with due

an Officer of the Company. 
  
 (f) The Trustee shall be under no
obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders unless such Holders shall have offered to the Trustee security or indemnity reasonably satisfactory to it against the

 (g) Except with respect to Section 4.01, the Trustee shall have no duty to inquire as to the performance of the Company with respect to the covenants

Default or Event of Default of which the Trustee shall have received written notification or obtain actual knowledge. 
  

 79 

 (h) Delivery of reports, information and documents to the Trustee under Section 4.03 is for
informational purposes only and the Trustee’s receipt of the foregoing shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance
with any of their covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates). 
  
 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 become a creditor of,
or otherwise deal with, the Company or any of its 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 described in the TIA (as in effect at such time), it
must eliminate such conflict within 90 days, apply to the Commission for permission to continue as trustee or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11. 
  
 Section 7.04. Trustee’s Disclaimer. 

 
 The Trustee shall not be responsible for and makes no representation as
to the validity or adequacy of this Indenture, it shall not be accountable for the Company’s use of the proceeds from the Notes or any money paid to the Company or upon the Company’s direction under any provision of this Indenture, it
shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it shall not be responsible for any statement or recital herein or any statement in the Notes or any other document in
connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication. 
  
 Section 7.05. Notice of Defaults. 
  
 If a Default or Event of Default occurs and is continuing and if it is known to the Trustee, the Trustee shall mail to Holders of Notes a notice of the
Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default relating to the payment of principal of, or premium, if any, interest or Additional Interest, if any, on, any Note, the Trustee may
withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of the Notes. 
  
 Section 7.06. Reports by Trustee to Holders of the Notes. 
  
 (a) Within 60 days after each May 15 beginning with May 15, 2006,
and for so long as Notes remain outstanding, the Trustee shall mail to the Holders of the Notes a brief report dated as of such reporting date that complies with TIA Section 313(a) (but if no event described in TIA Section 313(a) has
occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also shall comply with TIA Section 313(b)(2). The Trustee shall also transmit by mail all reports as required by TIA
Section 313(c). 
  
 (b) A copy of each report at the time of
its mailing to the Holders of Notes shall be mailed to the Company and filed with the Commission and each stock exchange on which the Notes are listed in accordance with TIA Section 313(d). The Company shall promptly notify the Trustee when the
Notes are listed on any stock exchange or any delisting thereof. 
  

 80 

 Section 7.07. Compensation and Indemnity. 
  
 (a) The Company shall pay to the Trustee from time to time reasonable
compensation for its acceptance of this Indenture and services hereunder in accordance with a written schedule as agreed by the Trustee and the Company. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of
an express trust. The Company shall 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 shall include the
reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel. 
  
 (b) The Company shall indemnify the Trustee against any and all losses, liabilities or expenses 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 (including this Section 7.07) and defending itself against any claim (whether asserted by either of the Company or any Holder or any other person) or liability in
connection with the 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, bad faith or willful misconduct. The Trustee shall notify the
Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder unless the failure to notify the Company impairs the Company’s ability to
defend such claim. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Company need not pay for any settlement made without its consent. 
  
 (c) The obligations of the Company under this Section 7.07 shall survive the satisfaction and discharge of this
Indenture and resignation of removal of the Trustee. 
  
 (d) To
secure the Company’s payment obligations in this Section 7.07, the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on
particular Notes. Such Lien shall survive the satisfaction and discharge of this Indenture and resignation or removal of the Trustee. 
  
 (e) When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(i) and (j) hereof occurs, the
expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law. 
  
 (f) The Trustee shall comply with the provisions of TIA Section 313(b)(2) to the extent applicable. 
  
 Section 7.08. Replacement of Trustee. 
  
 (a) A resignation or removal of the Trustee and appointment of a successor
Trustee shall become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 7.08. 
  

 81 

 (b) The Trustee may resign in writing at any time and be discharged from the trust hereby created by so
notifying the Company. The Holders of a majority in principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Company in writing. The Company may remove the Trustee if: 
  
 (i) the Trustee fails to comply with Section 7.10;

  
 (ii) the Trustee is adjudged a bankrupt or an
insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law; 
  
 (iii) a custodian or public officer takes charge of the Trustee or its property; or 
  
 (iv) the Trustee becomes incapable of acting. 
  
 (c) If the Trustee resigns or is removed or if a vacancy exists in the office
of Trustee for any reason, the Company shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the then outstanding Notes may appoint a successor Trustee
to replace the successor Trustee appointed by the Company. 
  
 (d)
If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company, or the Holders of at least 10% in principal amount of the then outstanding Notes may petition at the
expense of the Company 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, 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 shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, the resignation or
removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders. The retiring
Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07. Notwithstanding
replacement of the Trustee pursuant to this Section 7.08, the Company’s obligations under Section 7.07 shall continue for the benefit of the retiring Trustee. 
  
 Section 7.09. Successor Trustee by Merger, Etc. 
  
 If the Trustee consolidates, merges or converts into, or transfers all or
substantially all of its corporate trust business to, another Person, the successor Person without any further act shall be the successor Trustee. 
  

 82 

 Section 7.10. Eligibility; Disqualification. 
  
 There shall at all times be a Trustee hereunder that is a corporation
organized and doing business under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trust powers, that is subject to supervision or examination by federal or state authorities
and that has a combined capital and surplus of at least $50.0 million as set forth in its most recent published annual report of condition.

Section 310(b). 
  
 Section 7.11.
Preferential Collection of Claims Against Company. 
  
 The
Trustee is subject to TIA Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee who has resigned or been removed shall be subject to TIA Section 311(a) to the extent indicated therein. The Trustee
hereby waives any right to set off any claim that it may have against the Company in any capacity (other than as Trustee and Paying Agent) against any of the assets of the Company held by the Trustee; provided, however, that if the
Trustee is or becomes a lender of any other Indebtedness permitted hereunder to be pari passu with the Notes, then such waiver shall not apply to the extent of such Indebtedness. 
  
 ARTICLE EIGHT 
 DEFEASANCE AND COVENANT DEFEASANCE 
  
 Section 8.01. Option to Effect Legal Defeasance or Covenant Defeasance. 
  
 The Company may, at the option of the Board of Directors evidenced by a resolution set forth in an Officers’ Certificate, at any time, elect to have either Section 8.02 or 8.03 be applied to all outstanding
Notes upon compliance with the conditions set forth below in this Article Eight. In addition, subject to compliance with this Article Eight, the Company may exercise its option under Section 8.02 notwithstanding the prior exercise of its option
under Section 8.03. 
  
 Section 8.02.
Legal Defeasance and Discharge. 
  
 Upon the
Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Company shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from
its obligations with respect to all outstanding Notes and all obligations of each of the Guarantors shall be deemed to have been discharged with respect to its obligations under its Note Guarantee on the date the conditions set forth below are
satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Company and each Guarantor shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes and
the relevant Note Guarantee, respectively which shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 and the other Sections of this Indenture referred to in (a) and (b) below, and to have
satisfied all its other obligations under such Notes, this Indenture and such Note Guarantee (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments 

  

 83 

 
acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder: 
  
 (a) the rights of Holders of outstanding Notes to receive payments in respect
of the principal of, and premium, if any, interest and Additional Interest, if any, on, such Notes when such payments are due from the trust referred to in Section 8.04; 
  
 (b) the Company’s obligations with respect to the Notes concerning issuing temporary Notes, registration of Notes,
mutilated, destroyed, lost or stolen Notes under Article Two and the maintenance of an office or agency for payment and money for security payments held in trust under Section 4.02; 
  
 (c) the rights, powers, trusts, duties and immunities of the Trustee, and the Company’s and each Guarantor’s
obligations in connection therewith; and 
  
 (d) this Article
Eight. 
  
 Section 8.03. Covenant
Defeasance. 
  
 Upon the Company’s exercise under
Section 8.01 hereof of the option applicable to this Section 8.03, the Company and each of the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from their obligations under
the covenants contained in Sections 3.08, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14, 4.16, 4.17, 4.18, 4.19 and 5.01 (and the corresponding provisions of the Notes) with respect to the outstanding Notes and the related Note Guarantees on and
after the date the conditions set forth in Section 8.04 are satisfied (hereinafter, “Covenant Defeasance”), and the Notes shall thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent
or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes shall not be
deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Company and each Guarantor may omit to comply with and shall have no liability in respect of any term,
condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other
document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.01, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon the
Company’s exercise under Section 8.01 of the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04, Sections 6.01(c) through (f) shall not constitute Events of
Default. 
  
 Section 8.04. Conditions to Legal
or Covenant Defeasance. 
  
 (a) The following shall be the
conditions to the application of either Section 8.02 or 8.03 to the outstanding Notes: 
  
 (i) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of the Notes, cash in U.S. dollars
and/or non-callable Government 

  

 84 

 
Securities (if applicable, in combination with Qualified Interest Rate Agreements) that through the payment of interest and principal (in respect of such
Government Securities) or other amounts (in respect of such Qualified Interest Rate Agreements) will provide funds (net of any amounts payable by the trust pursuant to any such Qualified Interest Rate Agreements) as will be sufficient, in the
opinion of a nationally recognized firm of independent public accountants, to pay the principal of, and premium, if any, interest and Additional Interest, if any, on, the outstanding Notes on the Stated Maturity or on the applicable redemption date,
as the case may be, and the Company must specify whether the Notes are being defeased to maturity or to a particular redemption date; 
  
 (ii) in the case of Legal Defeasance, the Company shall have delivered to the Trustee an Opinion of Counsel reasonably acceptable to the
Trustee confirming that (a) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (b) since the Issue Date, there has been a change in the applicable federal income tax law, in either case
to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of the outstanding Notes shall not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and shall be subject
to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred; 
  
 (iii) in the case of Covenant Defeasance, the Company shall have delivered to the Trustee an Opinion of Counsel reasonably acceptable to
the Trustee confirming that the Holders of the outstanding Notes shall not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and shall be subject to federal income tax on the same amounts, in the
same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 
  
 (iv) no Default or Event of Default shall have occurred and be continuing on the date of such deposit; 
  
 (v) such Legal Defeasance or Covenant Defeasance shall not
result in a breach or violation of, or constitute a default under any material agreement or instrument to which Holdings or any of its Subsidiaries is a party or by which Holdings or any of its Subsidiaries is bound; 
  
 (vi) the Company must have delivered to the Trustee an
Opinion of Counsel to the effect that (1) assuming no intervening bankruptcy of the Company or any Guarantor between the date of deposit and the 123rd day following the deposit and assuming that no Holder is an “insider” of the Company under applicable bankruptcy law, after the 123rd day following the deposit, the trust funds shall not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws
affecting creditors’ rights generally, including Section 547 of the United States Bankruptcy Code and Section 15 of the New York Debtor and Creditor law and (2) the creation of the defeasance trust does not violate the Investment
Company Act of 1940; 
  

 85 

 (vii) the Company must deliver to the Trustee an Officers’ Certificate stating that
the deposit was not made by the Company with the intent of defeating, hindering, delaying or defrauding creditors of the Company or others;

redeem all of the Notes on the specified redemption date; and

complied with. 
  
 Section 8.05. Deposited
Money and Government Securities to Be Held in Trust; Other Miscellaneous Provisions. 
  
 (a) Subject to Section 8.06, all money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee pursuant to Section 8.04 in respect of the outstanding Notes shall be
held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as Paying Agent) as the Trustee may determine, to
the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, interest and Additional Interest, if any, but such money need not be segregated from other funds except to the extent required by law.

  
 (b) The Company shall pay and indemnify the Trustee against
any tax, fee or other charge imposed on or assessed against the cash or non-callable Government Securities deposited pursuant to Section 8.04 or the principal and interest received in respect thereof other than any such tax, fee or other charge
which by law is for the account of the Holders of the outstanding Notes. 
  
 (c) Anything in this Article Eight to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon the request of the Company any money or non-callable Government Securities
held by it as provided in Section 8.04 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under
Section 8.04(a)), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance. 
  
 Section 8.06. Repayment to the Company. 
  
 Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of, or premium, if any, interest or Additional Interest, if any, on, any Note and remaining unclaimed for two years after such principal, premium, if any, interest or Additional Interest, if
any, has become due and payable shall be paid to the Company on its request or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter look only to the Company for payment thereof, and all
liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the 

  

 86 

 
Trustee or such Paying Agent, before being required to make any such repayment, may at the reasonable expense of the Company cause to be published once, in
The New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such notification or
publication, any unclaimed balance of such money then remaining shall be repaid to the Company. 
  
 Section 8.07. Reinstatement. 
  
 If the Trustee or Paying Agent is unable to apply any United States dollars or non-callable Government Securities in accordance with Section 8.02 or
8.03, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s obligations under this Indenture and the Notes shall be
revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 and, in the case of a Legal Defeasance, each Guarantor’s obligations under its Note Guarantee shall be revised and reinstated as though no deposit
had occurred pursuant to Section 8.02, in each case, until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03, as the case may be; provided, however, that, if
the Company makes any payment of principal of, or premium, if any, interest or Additional Interest, if any, on, any Note following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to
receive such payment from the money held by the Trustee or Paying Agent. 
  
 ARTICLE NINE 
 AMENDMENT, SUPPLEMENT AND WAIVER 
  
 Section 9.01. Without Consent of Holders of Notes. 
  
 (a) Notwithstanding Section 9.02, the Company, the Guarantors and the
Trustee may amend or supplement this Indenture, the Notes, the Collateral Documents or the Intercreditor Agreement without the consent of any Holder of a Note: 
  

(i) to cure any ambiguity, defect or inconsistency; 
  
 (ii) to provide for uncertificated Notes in addition to or in place of certificated Notes; 
  
 (iii) to provide for the assumption of the Company’s or
any Guarantor’s obligations to Holders of Notes in the case of a merger or consolidation or sale of all or substantially all of the Company’s or such Guarantor’s assets; 
  
 (iv) to make any change that would provide any additional rights or benefits to the Holders of Notes or that
does not materially adversely affect the legal rights under this Indenture of any such Holder; 
  
 (v) to comply with requirements of the Commission in order to effect or maintain the qualification of this Indenture under the Trust
Indenture Act of 1939; 
  

 87 

 (vi) to comply with Section 4.17; 
  
 (vii) to evidence and provide for the acceptance of
appointment by a successor Trustee; 
  
 (viii) to
enter into additional or supplemental Collateral Documents or to make amendments thereto required by the Intercreditor Agreement; or 
  
 (ix) to provide for the issuance of Additional Notes in accordance with this Indenture. 
  
 Upon the request of the Company accompanied by a resolution of its Board of
Directors authorizing the execution of any such amendment or supplement to this Indenture, the Collateral Documents or the Intercreditor Agreement, and upon receipt by the Trustee of any documents requested under Section 7.02(b), the Trustee
shall join with the Company and the Guarantors in the execution of such amendment or supplement and the making of any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to enter into
any such amendment or supplement that affects its own rights, duties or immunities under this Indenture or otherwise. 
  
 Section 9.02. With Consent of Holders of Notes. 
  
 (a) Except as otherwise provided in this Section 9.02, the Company, the Guarantors and the Trustee may amend or
supplement this Indenture, the Notes, the Collateral Documents or the Intercreditor Agreement with the consent of the Holders of at least a majority in principal amount of the Notes then outstanding (including, without limitation, consents obtained
in connection with a purchase of, or tender offer or exchange offer for, Notes), and, subject to Sections 6.04 and 6.07, any existing Default or Event of Default or compliance with any provision of this Indenture, the Notes or the Collateral
Documents may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for,
Notes). 
  
 (b) The Company may, but shall not be obligated to,
fix a record date for the purpose of determining the Persons entitled to consent to any indenture supplemental hereto or any amendment to the Collateral Documents or the Intercreditor Agreement. If a record date is fixed, the Holders on such record
date, or its duly designated proxies, and only such Persons, shall be entitled to consent to such supplemental indenture, amended Collateral Documents or amended Intercreditor Agreement, as the case may be, whether or not such Holders remain Holders
after such record date; provided that unless such consent shall have become effective by virtue of the requisite percentage having been obtained prior to the date which is 120 days after such record date, any such consent previously given
shall automatically and without further action by any Holder be cancelled and of no further effect. 
  
 (c) Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amendment or supplement to
this Indenture, the Collateral Documents or the Intercreditor Agreement, and, upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid 

  

 88 

 
and upon receipt by the Trustee of the documents described in Section 7.02(b), the Trustee shall join with the Company in the execution of such
amendment or supplement and the making of any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to enter into any such amendment or supplement that affects its own rights, duties or
immunities under this Indenture or otherwise. 
  
 (d) It shall not
be 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 shall be sufficient if such consent approves the substance thereof. 

 
 (e) After an amendment, supplement or waiver under this Section becomes
effective, the Company shall mail to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair
or affect the validity of any such amendment, supplement or waiver. Subject to Sections 6.04 and 6.07, the Holders of a majority in aggregate principal amount of the then outstanding Notes (including Additional Notes, if any) may waive compliance in
a particular instance by the Company with any provision of this Indenture, or the Notes. However, without the consent of each Holder affected, an amendment or waiver under this Section 9.02 may not (with respect to any Notes held by a
non-consenting Holder): 
  
 (i) reduce the
percentage of principal amount of Notes whose Holders must consent to an amendment, supplement or waiver; 
  
 (ii) reduce the principal of or change the fixed maturity of any Note or alter the provisions, or waive any payment, with respect to the
redemption of the Notes; 
  
 (iii) reduce the
rate of or change the time for payment of interest on any Note; 
  
 (iv) waive a Default or Event of Default in the payment of principal of, or premium, if any, interest or Additional Interest, if any, on, the Notes (except a rescission of acceleration of the Notes by the Holders of
at least a majority in aggregate principal amount of the Notes and a waiver of the payment default that resulted from such acceleration); 
  
 (v) make any Note payable in money other than U.S. dollars; 
  
 (vi) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights
of Holders of Notes to receive payments of principal of, or premium, if any, interest or Additional Interest, if any, on, the Notes; 
  
 (vii) release any Guarantor from any of its obligations under its Note Guarantee or this Indenture, except in accordance with the terms of
this Indenture; 
  
 (viii) impair the right to
institute suit for the enforcement of any payment on or with respect to the Notes or the Note Guarantees; 
  

 89 

 (ix) amend, change or modify the obligation of the Company to make and consummate an
Asset Sale Offer with respect to any Asset Sale in accordance with Section 4.10 hereof after the obligation to make such Asset Sale Offer has arisen, or the obligation of the Company to make and consummate a Change of Control Offer in the event
of a Change of Control in accordance with Section 4.14 hereof after such Change of Control has occurred, including, in each case, amending, changing or modifying any definition relating thereto; 
  
 (x) except as otherwise permitted under Section 4.17
hereof and Section 5.01 hereof, consent to the assignment or transfer by the Company or any Subsidiary Guarantor of any of their rights or obligations under this Indenture; 
  
 (xi) amend or modify any of the provisions of this Indenture or the related definitions affecting the
ranking of the Notes or any Note Guarantee in any manner adverse to the Holders of the Notes or any Note Guarantee; 
  
 (xii) release the Collateral from the Note Liens, except in accordance with the provisions hereof and in accordance with the Intercreditor
Agreement and the Collateral Documents; or 
  
 (xiii) make any change in the preceding amendment and waiver provisions. 
  
 Section 9.03. Compliance with Trust Indenture Act. 
  
 Every amendment or supplement to this Indenture, the Notes, the Collateral Documents or the Intercreditor Agreement shall be
set forth in a document that complies with the TIA as then in effect. 
  
 Section 9.04. 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 waiver, supplement or amendment becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder. 
  
 Section 9.05. Notation on or Exchange of Notes.

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

 90 

 Section 9.06. Trustee to Sign Amendments, Etc. 
  
 The Trustee shall sign any amendment or supplement to this Indenture, any
Note, any Collateral Documents or the Intercreditor Agreement authorized pursuant to this Article Nine if such amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Company may not sign
an amendment or supplemental Indenture or Note until its Board of Directors approves it. In executing any amendment or supplement or Note, the Trustee shall be entitled to receive and (subject to Section 7.01) shall be fully protected in
relying upon an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amendment or supplement is authorized or permitted by this Indenture. 
  
 ARTICLE TEN 
 NOTE GUARANTEES 
  
 Section
10.01. Guarantee. 
  
 (a) Subject to this Article Ten,
each of the Guarantors hereby, jointly and severally, and fully and unconditionally, guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and
enforceability of this Indenture, the Notes or the obligations of the Company hereunder or thereunder, that: (i) the principal of, and premium, if any, interest and Additional Interest, if any, on, the Notes will be promptly paid in full when
due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of, and premium, if any, interest and Additional Interest, if any, on, the Notes, if lawful (subject in all cases to any applicable grace
period provided herein), and all other obligations of the Company 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 (ii) in case of any extension of
time of payment or renewal of any Notes or any of such other obligations, the 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 Guarantors shall be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

  
 (b) The Guarantors hereby agree that, to the maximum extent
permitted under applicable law, their obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by
any Holder of the Notes with respect to any provisions hereof or thereof, 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. Subject to Section 6.06, each 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 this Note Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes and this Indenture. 
  

 91 

 (c) If any Holder or the Trustee is required by any court or otherwise to return to the Company, the
Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to any of the Company or the Guarantors, any amount paid by any of them to the Trustee or such Holder, the Note Guarantee provided for herein, to the
extent theretofore discharged, shall be reinstated in full force and effect. 
  
 (d) Each Guarantor agrees that it shall 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 Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article Six for
the purposes of the Note Guarantee provided for herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any declaration of
acceleration of such obligations as provided in Article Six hereof, such obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantors for the purpose of the Note Guarantee provided for herein. The Guarantors
shall have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Note Guarantee provided for herein. 
  
 Section 10.02. Limitation on Guarantor Liability.

  
 Each Guarantor, and by its acceptance of Notes, each Holder,
hereby confirms that it is the intention of all such parties that the Note Guarantee of such Guarantor not constitute (i) a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform
Fraudulent Transfer Act or any similar federal or state law to the extent applicable to its Note Guarantee or (ii) an unlawful distribution under any applicable state law prohibiting shareholder distributions by an insolvent subsidiary to the
extent applicable to its Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor will be limited to the maximum amount as will, after giving
effect to all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in
respect of the obligations of such other Guarantor under this Article Ten, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent transfer or conveyance or such an unlawful distribution. 
  
 Section 10.03. Note Guarantee Under Indenture.

  
 (a) If an Officer whose signature is on this Indenture no
longer holds that office at the time the Trustee authenticates the Note, the Note Guarantee provided for herein shall be valid nevertheless. 
  
 (b) The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Note Guarantee provided for
herein on behalf of the Guarantors. 
  

 92 

 (c) If required by Section 4.17, the Company shall cause its Subsidiaries to (i) execute
supplemental indentures to this Indenture providing for additional Note Guarantees in accordance with Section 4.17 and this Article Ten, to the extent applicable and (ii) grant a valid and perfected security interest (subject to the terms
of the Intercreditor Agreement) to the Trustee and the Holders of Notes in all of their respective properties and assets constituting Collateral securing their obligations under such Note Guarantees. 
  
 Section 10.04. Release of Guarantor. 
  
 (a) The Note Guarantee of a Subsidiary Guarantor shall be released in
accordance with the provisions of Section 4.17(d). 
  
 (b)
Upon Legal Defeasance in accordance with Article Eight or satisfaction and discharge of this Indenture in accordance with Article Eleven, each Guarantor will be released from, and relieved of all of its obligations under, its Note Guarantee.

  
 (c) Any Guarantor not released from its obligations under its
Note Guarantee pursuant to clause (a) or (b) of this Section 10.04 shall remain liable for the full amount of principal of, and premium, if any, interest and Additional Interest, if any, on, the Notes and for the other obligations of
any Guarantor under this Indenture as provided in this Article Ten. 
  
 ARTICLE ELEVEN 
 SATISFACTION AND DISCHARGE 
  
 Section 11.01. Satisfaction and Discharge. 
  
 (a) This Indenture shall be discharged and shall cease to be of further
effect as to all Notes issued hereunder, when:

through the payment of interest and principal (in respect of such Government Securities) or other amounts (in respect of such Qualified Interest Rate Agreements) will provide funds (net of any amounts payable by the trust pursuant to any such
Qualified Interest Rate Agreements) as shall be sufficient, without consideration of any reinvestment of interest, to pay and discharge the entire indebtedness on the Notes

not delivered to the Trustee for cancellation for principal, premium, if any, and accrued and unpaid interest and Additional Interest, if any, to the date of

Notwithstanding the above, the Trustee shall pay to the Company from time to time upon its request any cash or Government Securities held by it as provided in this section which, in the opinion of a nationally recognized firm of independent public
accountants expressed in a written certification delivered to the Trustee, are in excess of the amount thereof that would then be required to be deposited to effect a satisfaction and discharge under this Article Eleven. 
  
 (d) After the conditions to discharge contained in this Article Eleven have
been satisfied, and the Company has paid or caused to be paid all other sums payable hereunder by the Company, and delivered to the Trustee an Officers’ Certificate and Opinion of Counsel, each stating that all conditions precedent to
satisfaction and discharge have been satisfied, the Trustee upon written request shall acknowledge in writing the discharge of the obligations of the Company and the Subsidiary Guarantors, if any, under this Indenture (except for those surviving
obligations specified in Section 8.02).

liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required
to make any such repayment, may at the reasonable expense of the Company cause to be published once, in The New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date

any income therefrom. 
  
 (b) In the event of the consummation of
any sale, transfer or other disposition of any property or assets that are subject to any Note Liens, which sale, transfer or other disposition is in accordance with the terms of this Indenture, the Intercreditor Agreement and the Collateral
Documents, the Collateral Agent will, regardless of whether such release is automatic, at the Company’s expense, execute and deliver to the Company or the applicable Guarantor such documents as the Company or such Guarantor shall reasonably
request to evidence the release of such item of Collateral from the Note Liens; provided that the Company shall have delivered to the Collateral Agent, at least five Business Days prior to the date of the proposed release, a written request
for release describing the item of Collateral and the terms of the sale, lease, transfer or other disposition in reasonable detail, including, without limitation, the price thereof and any expenses in connection therewith, together with a form of
release for execution by the Collateral Agent and a certificate of the Company to the effect that the transaction is in compliance with the Indenture, the Intercreditor Agreement and the Collateral Documents, and as to such other matters as the
Trustee may request. Notwithstanding the foregoing, the requirements of this Section 12.04(b) shall not apply to releases of Collateral pursuant to Section 12.04(f). 
  
 (c) Notwithstanding anything to the contrary in Section 12.04(b), the Note Liens on inventory sold in the ordinary

 (e) In the event that any of the Collateral is released with the consent of
the Holders in accordance with Section 9.02 hereof, the Note Liens on such Collateral shall be released.

a number of activities in the ordinary course in respect of the Collateral to the extent not restricted or prohibited by the Collateral Documents and this Indenture. The release of any Collateral from the Note Liens pursuant to the terms of this
Indenture, the Collateral Documents and the 

  

 97

the Collateral is released pursuant to the terms of this Section 12.04. 
  
 Section 12.05. Opinion of Counsel. 
  
 So long as the Collateral Documents have not been terminated in accordance with the terms thereof, the Company shall deliver to the Collateral Agent, so long as such delivery is required by Section 314(b) of the

action is necessary to maintain such Note Liens. 
  
 Section 12.06. Further Assurances.

identifying and describing the Collateral and such other reports in connection with the Collateral as the Collateral Agent may request, all in such detail as the Collateral Agent may request; (b) subject to the Intercreditor Agreement, at any
time and from time to time, upon the written request of the Collateral Agent, and at the sole expense of the Company or such Guarantor, promptly execute, acknowledge, deliver, record, re-record, file, re-file, register and re-register, as
applicable, any and all such further acts, deeds, conveyances, security agreements, mortgages, assignments, estoppel certificates, financing statements and continuations thereof (including, without limitation, any financing or continuation
statements under the Uniform Commercial Code (or other similar laws) in effect in any jurisdiction with respect to the Note Liens), termination statements, notices of assignment, transfers, certificates, assurances and other instruments as may be
required from time to time in order to (i) subject to the Note Liens any of the property or assets constituting Collateral and (ii) perfect and maintain the validity, effectiveness, perfection and priority of any of the Note Liens;
(c) subject to the Intercreditor Agreement and without limitation of the foregoing subsection (b), with respect to any fee interest in real property acquired after the Issue Date by the Company or any Guarantor, to the extent the Company or
such Guarantor would be required (pursuant to the terms of the Credit Agreement as in effect on the Issue Date) to execute and deliver a Mortgage on such real property in favor of the lenders under the Credit Agreement, promptly (i) execute and
deliver a Mortgage in favor of the Collateral Agent, creating a security interest for the benefit of the Holders of the Notes, covering such real property, and (ii) deliver to the Collateral Agent title and extended coverage insurance covering
such real property in an amount at least equal to the purchase price of such real property, with local fixture filings being made in respect of fixtures associated with such real property as well as a current ALTA survey thereof, together with a

 (b) Notwithstanding anything to the contrary in this Section 12.07, the
Company will not be required to comply with all or any portion of § 314(d) of the TIA if the Board of Directors of the Company determines, in good faith based on advice of counsel, that, under the terms of § 314(d) of the TIA
and/or any interpretation or guidance as to the meaning thereof of the Commission or its staff, including publicly available “no action” letters or exemptive orders, all or any portion of § 314(d) of the TIA is inapplicable to
one or a series of released Collateral. 
  
 (c) The fair value of
Collateral released from the Liens of this Indenture and the Collateral Documents pursuant to Section 12.04 hereof shall not be considered in determining whether the aggregate fair value of Collateral released from the Liens of this Indenture
and the Collateral Documents in any calendar year exceeds the 10% threshold specified in Section 314(d)(1) of the TIA. It is expressly understood that subsection (b) of this Section 12.07 and this subsection (c) relate only to
the Company’s obligations under the TIA and shall not restrict or otherwise affect the Company’s and its Subsidiaries’ rights or abilities, or the rights or abilities of the administrative agent under the Credit Agreement, to release
Collateral pursuant to the terms of this Indenture, the Intercreditor Agreement and the Collateral Documents or as otherwise permitted by the Trustee and the Collateral Agent under this Indenture, the Intercreditor Agreement and the Collateral
Documents. 
  
 Section 12.08. Suits to Protect
the Collateral. 
  
 Subject to the provisions of the
Intercreditor Agreement and the Collateral Documents, the Collateral Agent shall have the authority to institute and to maintain such suits and proceedings as the Collateral Agent may deem expedient to prevent any impairment of the Collateral by any
acts which may be unlawful or in violation of any of the Collateral Documents or this Indenture, and such suits and proceedings as the Collateral Agent may deem expedient to preserve or protect its interests and the interests of the Holders of the
Notes in the Collateral (including suits or proceedings to restrain the enforcement of or compliance with any legislative or other governmental enactment, rule or order that may be unconstitutional or otherwise invalid if the enforcement of, or
compliance with, such enactment, rule or order would impair the Note Liens or be prejudicial to the interests of the Holders of the Notes). 
  
 Section 12.09. Purchaser Protected. 
  
 In no event shall any purchaser in good faith or other transferee of any property purported to be released hereunder be bound to ascertain the authority
of the Collateral Agent to execute the release or to inquire as to the satisfaction of any conditions required by the provisions hereof for the exercise of such authority or to see to the application of any consideration given by such purchaser or
other transferee; nor shall any purchaser or other transferee of any property or rights permitted to be sold by this Article Twelve, be under 

  

 99 

 
obligation to ascertain or inquire into the authority of the Company or any Guarantor, as applicable, to make any such sale or other transfer. 
  
 Section 12.10. Powers Exercisable by Receiver or
Trustee. 
  
 In case the Collateral shall be in the
possession of a receiver or trustee, lawfully appointed, the powers conferred in this Article Twelve upon the Company or any Guarantor, as applicable, with respect to the release, sale or other disposition of such property may be exercised by
such receiver or trustee, and an instrument signed by such receiver or trustee shall be deemed the equivalent of any similar instrument of the Company or any Guarantor, as applicable, or of any officer or officers thereof required by the provisions
of this Article Twelve. 
  
 Section 12.11.
Release of Note Liens. 
  
 In the event that any Note
Liens shall be released pursuant to the terms of this Indenture, the Collateral Agent shall (a) promptly execute and deliver such releases, termination statements and other instruments (in recordable form, where appropriate) as the Company or
any Guarantor, as applicable, may reasonably request to evidence the termination of such Note Liens and (b) not be deemed to hold such Note Liens for its benefit and the benefit of the Holders of the Notes.

 Section 13.14. Acts of Holders.

  
 (a) Any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Indenture to be given or taken by the Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agents duly appointed in
writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or
instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing
appointing any such agent shall be sufficient for any purpose of this Indenture and conclusive in favor of the Trustee and the Company if made in the manner provided in this Section 13.14. 
  
 (b) The fact and date of the execution by any Person of any such instrument
or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing
acknowledged to such witness, notary or officer the execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of authority.
The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner which the Trustee deems sufficient. 
  
 (c) Notwithstanding anything to the contrary contained in this
Section 13.14, the principal amount and serial numbers of Notes held by any Holder, and the date of holding the same, shall be proved by the register of the Notes maintained by the Registrar as provided in Section 2.04. 
  
 (d) If the Company shall solicit from the Holders of the Notes any request,
demand, authorization, direction, notice, consent, waiver or other Act, the Company may, at its option, by or pursuant to a resolution of its Board of Directors, fix in advance a record date for the determination of Holders entitled to give such
request, demand, authorization, direction, notice, consent, waiver or other Act, but the Company shall have no obligation to do so. Notwithstanding TIA Section 316(c), such record date shall be the record date specified in or pursuant to such
resolution, which shall be a date not earlier than the date 30 days prior to the first solicitation of Holders generally in connection therewith or the date of the most recent list of 

  

 104 

 
Holders forwarded to the Trustee prior to such solicitation pursuant to Section 2.06 and not later than the date such solicitation is completed. If such
a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of record at the close of business on such record date shall be deemed
to be Holders for the purposes of determining whether Holders of the requisite proportion of the then outstanding Notes have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act,
and for that purpose the then outstanding Notes shall be computed as of such record date; provided that no such authorization, agreement or consent by the Holders on such record date shall be deemed effective unless it shall become effective
pursuant to the provisions of this Indenture not later than one year after the record date. 
  
 (e) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Note shall bind every future Holder of the same Note and the Holder of every Note issued upon the
registration or transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Note.

  
 (f) Without limiting the foregoing, a Holder entitled
hereunder to take any action hereunder with regard to any particular Note may do so itself with regard to all or any part of the principal amount of such Note or by one or more duly appointed agents each of which may do so pursuant to such
appointment with regard to all or any part of such principal amount. 
  
 Section 13.15. Benefit of Indenture. 
  
 Nothing in this Indenture, the Notes, express or implied, shall give to any Person, other than the parties hereto, any Paying Agent, any Registrar and its successors hereunder, and the Holders, any benefit or any
legal or equitable right, remedy or claim under this Indenture. 
  
 Section 13.16. Table of Contents, Headings, Etc. 
  
 The Table of Contents, Cross-Reference Table and Headings of the Articles and Sections of this Indenture have been inserted for convenience of reference only, are not to be considered a part of this Indenture and

 MSC-MEDICAL SERVICES COMPANY 
  
 Senior Secured Floating Rate Notes due 2011 
  
 Capitalized terms used herein shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated. 
  
 1. Interest. Interest on the Notes will accrue at the rate per annum,
reset quarterly, equal to LIBOR plus 7.50%, as determined by the calculation agent (the “Calculation Agent”), which shall initially be the Trustee, and will be payable quarterly in cash on each
October 15, January 15, April 15 and July 15, commencing October 15, 2005, to the Holders of record on the immediately preceding October 1, January 1, April 1 and July 1. 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 Issue Date. 
  
 “Determination Date,” with respect to an Interest Period, means the second London Banking Day preceding the first day of such Interest
Period. 
  
 “Interest Period” means the period
commencing on and including an interest payment date and ending on and including the day immediately preceding the next succeeding interest payment date, with the exception that the first Interest Period shall commence on and include the Issue Date
and end on and include October 14, 2005. 
  
 “LIBOR,” with respect to an Interest Period, means the rate (expressed as a percentage per annum) for deposits in United States dollars for a three-month period beginning on the second London Banking Day after the
Determination Date that appears on Telerate Page 3750 as of 11:00 a.m., London time, on the Determination Date. If Telerate Page 3750 does not include such a rate or is unavailable on a Determination Date, the Calculation Agent will request the
principal London office of each of four major banks in the London interbank market, as selected by the Calculation Agent, to provide such bank’s offered quotation (expressed as a percentage per annum), as of approximately 11:00 a.m., London
time, on such Determination Date, to prime banks in the London interbank market for deposits in a Representative Amount in United States dollars for a three-month period beginning on the second London Banking Day after the Determination Date. If at
least two such offered quotations are so provided, LIBOR for the Interest Period will be the arithmetic mean of such quotations. If fewer than two such quotations are so provided, the Calculation Agent will request each of three major banks in New
York City, as selected by the Calculation Agent, to provide such bank’s rate (expressed as a percentage per annum), as of approximately 11:00 a.m., New York City time, on such Determination Date, for loans in a Representative Amount in United
States dollars to leading European banks for a three-month period beginning on the second London Banking Day after the Determination Date. If at least two such rates are so provided, LIBOR for the Interest Period will be the arithmetic mean of such
rates. If fewer than two such rates are so provided, then LIBOR for the Interest Period will be LIBOR in effect with respect to the immediately preceding Interest Period. 
  

 A-5 

 “London Banking Day” is any day in which dealings in United States dollars are
transacted or, with respect to any future date, are expected to be transacted in the London interbank market. 
  
 “Representative Amount” means a principal amount of not less than U.S. $1,000,000 for a single transaction in the relevant market at the
relevant time. 
  
 “Telerate Page 3750” means the
display designated as “Page 3750” on the Moneyline Telerate service (or such other page as may replace Page 3750 on that service). 
  
 The amount of interest for each day that the Notes are outstanding (the “Daily Interest Amount”) will be calculated by dividing the
interest rate in effect for such day by 365 (or, if applicable, 366) and multiplying the result by the principal amount of the Notes. The amount of interest to be paid on the Notes for each Interest Period will be calculated by adding the Daily
Interest Amounts for each day in the Interest Period. 
  
 All
percentages resulting from any of the above calculations will be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point, with five one-millionths of a percentage point being rounded upwards (e.g., 8.876545% (or .08876545)
being rounded to 8.87655% (or .0887655)) and all dollar amounts used in or resulting from such calculations will be rounded to the nearest cent (with one-half cent being rounded upwards). 
  
 The interest rate on the Notes will in no event be higher than the maximum rate permitted by New York law as the same may be
modified by United States laws of general application. 
  
 The
Calculation Agent will, upon the request of the holder of any Note, provide the interest rate then in effect with respect to the Notes. All calculations made by the Calculation Agent in the absence of manifest error will be conclusive for all
purposes and binding on the Company, the Guarantors and the Holders of the Notes. 
  
 The Company shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time on demand at a rate that is 1% per annum in
excess of the rate then in effect; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace periods) from time to time on demand
at the same rate to the extent lawful. 
  
 2. Method of
Payment. The Company shall pay interest on the Notes (except defaulted interest) to the Persons who are registered Holders of Notes at the close of business on the October 1, January 1, April 1 or July 1 next
preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.13 of the Indenture with respect to defaulted interest. The Notes shall be
payable as to principal, premium, if any, interest and Additional Interest, if any, at the office or agency of the Company maintained for such purpose in The City of New York, or, at the option of the Company, payment of interest, may be made by
check mailed to the Holders at their addresses set forth in the register of Holders, and provided that payment by wire transfer of immediately available funds shall be required with respect to the principal of, and premium, if 

  

 A-6 

 
any, interest and Additional Interest, if any, on, all Global Notes and all other Notes the Holders of which shall have provided wire transfer instructions
to the Company or the Paying Agent. Such payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. 
  
 3. Paying Agent, Registrar and Calculation Agent. Initially, the
Trustee under the Indenture shall act as Paying Agent, Registrar and Calculation Agent. The Company may change any Paying Agent, Registrar or Calculation Agent without prior notice to any Holder. The Company or any of its Subsidiaries may act in any
such capacity. 
  
 4. Indenture. The Company issued the
Notes under an Indenture, dated as of June 21, 2005 (the “Indenture”), among the Company, Holdings and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference
to the Trust Indenture Act of 1939, as amended. The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. To the extent any provision of this Note conflicts with the express
provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Indenture pursuant to which this Note is issued provides that an unlimited principal amount of Additional Notes may be issued thereunder. 

 
 5. Optional Redemption. (a) At any time prior to
October 15, 2007, the Company may redeem up to 35% of the aggregate principal amount of Notes issued under the Indenture (including any Additional Notes) at a redemption price of 100% of the principal amount thereof plus a premium equal to the
interest rate per annum on the Notes applicable on the date on which notice of redemption is given, together with accrued and unpaid interest and Additional Interest, if any, thereon to the redemption date, with the net cash proceeds of one or more
Equity Offerings; provided that: 
  

	 	(i)	at least 65% of the aggregate principal amount of Notes issued under the Indenture (including any Additional Notes) remains outstanding immediately after the occurrence of such
redemption (excluding Notes held by the Company or its Affiliates); and 

  

	 	(ii)	the redemption must occur within 45 days of the date of the closing of such Equity Offering. 

  
 (b) Except pursuant to paragraph (a), the Company shall not have the option to redeem the Notes prior to
October 15, 2007. On or after October 15, 2007, the Company may redeem all or a part of the Notes upon not less than 30 nor more than 60 days’ notice, at the redemption prices (expressed as percentages of principal amount) set
forth below plus accrued and unpaid interest and Additional Interest, if any, thereon, to the applicable redemption date, if redeemed during the twelve-month period beginning on October 15 of the years indicated below:

	 2007
	  	103.000	%
	 2008
	  	101.500	%
	 2009 and thereafter
	  	100.000	%

  

 A-7 

 6. Selection and Notice of Redemption. If less than all of the Notes are to be redeemed at any
time, the Trustee shall select Notes for redemption as follows: (i) if the Notes are listed, in compliance with the requirements of the principal national securities exchange on which the Notes are listed, or (ii) if the Notes are not so
listed, on a pro rata basis, by lot or by any method as the Trustee deems fair and appropriate. No Notes of $1,000 principal amount or less shall be redeemed in part. Notices of redemption shall be mailed by first class mail at least 30 but not more
than 60 days before the redemption date to each Holder of Notes to be redeemed at its registered address. Notices of redemption may not be conditional. If any Note is to be redeemed in part only, the notice of redemption that relates to that Note
shall state the portion of the principal amount thereof to be redeemed. A new Note in principal amount equal to the unredeemed portion of the original Note shall be issued in the name of the Holder thereof upon cancellation of the original Note.
Notes called for redemption become due on the date fixed for redemption. On and after the redemption date, unless the Company defaults in the payment of the redemption price, Notes or portions thereof called for redemption shall cease to accrue
interest. 
  
 7. Repurchase at Option of Holder.
(a) Upon the occurrence of a Change of Control, each Holder of Notes shall have the right to require the Company to repurchase all or any part (equal to $1,000 principal amount or an integral multiple thereof) of that Holder’s Notes
pursuant to the offer described below (the “Change of Control Offer”) at an offer price in cash equal to 101% of the aggregate principal amount of the Notes repurchased plus accrued and unpaid interest and Additional Interest, if
any, thereon, to the date of repurchase (the “Change of Control Payment Date”), which date shall not be earlier than the date of such Change of Control. Within 30 days following any Change of Control, the Company shall mail a notice
to each Holder describing the transaction or transactions that constitute the Change of Control and offering to repurchase Notes on the Change of Control Payment Date specified in such notice, which date shall be no earlier than 30 days and no later
than 60 days from the date such notice is mailed, pursuant to the procedures required by the Indenture and described in such notice. 
  
 (b) If the Company or a Restricted Subsidiary consummates any Asset Sale, within 360 days of each date on which the aggregate amount of Excess Proceeds
exceeds $10.0 million, the Company shall make an offer to purchase (“Asset Sale Offer”), pursuant to Section 4.10 of the Indenture, to all Holders of Notes and all holders of pari passu debt (the “Pari Passu
Debt”) containing provisions similar to those set forth in the Indenture with respect to offers to purchase with the proceeds of sales of assets to purchase the maximum principal amount of Notes and Pari Passu Debt that may be purchased out
of the Excess Proceeds. The offer price in any Asset Sale Offer shall be equal to 100% of the aggregate principal amount of the Notes and Pari Passu Debt, plus accrued and unpaid interest and Additional Interest, if any, to the date of purchase, and
shall be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use such Excess Proceeds for any purpose not otherwise prohibited by the Indenture. If the aggregate principal amount of Notes and
Pari Passu Debt tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Notes and Pari 

  

 A-8 

 
Passu Debt shall be purchased on a pro rata basis based on the aggregate principal amount of Notes and Pari Passu Debt tendered. Upon completion of each
Asset Sale Offer, the Excess Proceeds subject to such Asset Sale shall no longer be deemed to be Excess Proceeds. 
  
 8. Denominations, Transfer, Exchange. The Notes are in registered form without coupons in denominations of $1,000 principal amount and integral
multiples thereof. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents
and the Company may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Company is not required to transfer or exchange any Note selected for redemption. Also, the Company is not required to transfer or
exchange any Note for a period of 15 days before a selection of Notes to be redeemed. 
  
 9. Persons Deemed Owners. The registered Holder of a Note shall be treated as the owner of it for all purposes. 
  
 10. Amendment, Supplement and Waiver. Subject to certain exceptions, the Indenture, the Notes, the Collateral Documents or the Intercreditor
Agreement may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the Notes then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or
exchange offer for, Notes), and any existing default or compliance with any provision of the Indenture, the Notes or the Collateral Documents may be waived with the consent of the Holders of a majority in principal amount of the then outstanding
Notes (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes). Without the consent of any Holder of Notes, the Company, the Guarantors and the Trustee may amend or supplement
the Indenture, the Notes, the Collateral Documents or the Intercreditor Agreement to, among other things, cure any ambiguity, defect or inconsistency, or make any change that does not materially adversely affect the legal rights under the Indenture
of any such Holder. 
  
 11. Defaults and Remedies. In the
case of an Event of Default under Sections 6.01(i) and (j), all unpaid principal of, and premium, if any, and accrued and unpaid interest and Additional Interest, if any, on, all outstanding Notes shall become due and payable immediately without
further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately by notice in
writing to the Company specifying the Event of Default and then all unpaid principal of, and premium, if any, interest and Additional Interest, if any, on, all outstanding Notes shall become due and payable immediately. 
  
 Holders of the Notes may not enforce the Indenture, the Notes, the Collateral
Documents or the Intercreditor Agreement except as provided in the Indenture and the Collateral Documents. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise
of any trust or power. The Trustee may withhold from Holders of the Notes notice of any Default or Event of Default (except a Default or Event of Default relating to the payment of principal, premium, if any, interest or Additional Interest, if any)
if it determines that withholding notice is in their interest. 
  

 A-9 

 In the case of any Event of Default occurring by reason of any willful action or inaction taken or not
taken by or on behalf of the Company with the intention of avoiding payment of the premium that the Company would have had to pay if the Company then had elected to redeem the Notes pursuant to Section 3.07 of the Indenture, an equivalent
premium shall also become and be immediately due and payable to the extent permitted by law upon the acceleration of the Notes. If an Event of Default occurs prior to the first date on which the Company may redeem the Notes pursuant to
Section 3.07, by reason of any willful action (or inaction) taken (or not taken) by or on behalf of the Company with the intention of avoiding the prohibition on redemption of the Notes prior to such date, then the premium specified in the
Indenture shall also become immediately due and payable to the extent permitted by law upon the acceleration of the Notes. 
  
 12. Trustee Dealings with Company. The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may become a
creditor of, or otherwise deal with the Company or any of its Affiliates, with the same rights it would have if it were not Trustee. 
  
 13. No Recourse Against Others. No director, officer, employee, incorporator, stockholder, member, manager or partner of the Company or any
Guarantor, as such, shall have any liability for any obligations of the Company or any Guarantor under the Notes, the Indenture, the Note Guarantees or the Collateral Documents or for any claim based on, in respect of, or by reason of, such
obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. This waiver and release are part of the consideration for issuance of the Notes. 
  
 14. Authentication. This Note shall not be valid until authenticated
by the manual signature of the Trustee or an authenticating agent. 
  
 15. CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers in
notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption and reliance may be placed only on the other identification
numbers placed thereon. 
  
 16. Guarantee. The
Company’s obligations under the Notes are fully and unconditionally guaranteed, jointly and severally, by the Guarantors. 
  
 17. Security Interest. The Company’s obligations under the Notes and the Indenture and each Guarantor’s obligation under its respective
Note Guarantee are secured by a second priority Lien on the Collateral.

 18. Copies of Documents. The Company shall furnish to any Holder upon written request and without
charge a copy of the Indenture, the Second Lien Security Agreement and the Intercreditor Agreement. Requests may be made to:
