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

The Notes shall be subject to repurchase by the Company pursuant to an Asset Sale Offer as provided in Section 4.16 or a Change of Control Offer as provided in Section 4.15, and otherwise as not prohibited by this Indenture.  The Notes shall not be redeemable, other than as provided in Article 3.

Additional Notes ranking pari passu with the Initial Notes may be created and issued from time to time by the Company without notice to or consent of the Holders and shall be consolidated with and form a single class with the Initial Notes and shall have the same terms as to status, redemption or otherwise (other than issue date, issue price and, if applicable, the first Interest Payment Date and the first date from which interest will accrue) as the Initial Notes; provided that the Company’s ability to issue Additional Notes shall be subject to the Company’s compliance with Section 4.09 and Section 4.10; provided, further, that unless such Additional Notes are issued under a separate CUSIP, such Additional Notes will be fungible with the Initial Notes for U.S. federal income tax purposes.

Section 2.02                             Execution and Authentication.

(a)                                 At least one Officer shall execute the Notes on behalf of the Company by manual or facsimile signature.  If an Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note shall nevertheless be valid.

(b)                                 A Note shall not be entitled to any benefit under this Indenture or be valid or obligatory for any purpose until authenticated substantially in the form of Exhibit A attached hereto by the manual signature of an authorized signatory of the Trustee.  The signature shall be conclusive evidence that the Note has been duly authenticated and delivered under this Indenture.

(c)                                  On the Issue Date, the Trustee shall, upon receipt of a written order of the Company signed by an Officer (an “Authentication Order”), authenticate and deliver the Initial Notes.  In addition, at any time and from time to time, the Trustee shall, upon receipt of an Authentication Order, authenticate and deliver any Additional Notes in an aggregate principal amount specified in such Authentication Order for such Additional Notes issued hereunder.

(d)                                 The Trustee may appoint an authenticating agent acceptable to the Company to authenticate Notes.  An authenticating agent may authenticate Notes whenever the Trustee may do so.  Each reference in this Indenture to authentication by the Trustee includes authentication by such agent.  An authenticating agent has the same rights as an Agent to deal with Holders, the Company or an Affiliate of the Company.

(e)                                  The Trustee shall authenticate and make available for delivery upon a written Authentication Order of the Company signed by one Officer of the Company (a) Initial Notes for original issue on the Issue Date in an aggregate principal amount of $300,000,000, (b) subject to the terms of this Indenture, Additional Notes and (c) any Unrestricted Global Notes issued in exchange for any of the foregoing in accordance with this Indenture.  Such Authentication Order shall specify the amount of the Notes to be authenticated, the date on which the original issue of Notes is to be authenticated and whether the Notes are to be Initial Notes, Additional Notes or Unrestricted Global Notes.

Section 2.03                             Registrar and Paying Agent.

(a)                                 The Company shall maintain an office or agency where Notes may be presented for registration of transfer or for exchange (“Registrar”) and at least one office or agency where Notes may be presented for payment (“Paying Agent”).  The Registrar shall keep a register of the Notes (“Note Register”) and of their transfer and exchange.  The Company may appoint one or more co-registrars and one or more additional paying agents.  The term “Registrar” includes any co-registrar, and the term “Paying Agent” includes any additional paying agent.  The Company may change any Paying Agent or Registrar without 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 may change the Paying or Registrar without prior notice to the Holders of the Notes, the Company or any of its Restricted Subsidiaries may act as Paying Agent or Registrar.

(b)                                 The Company initially appoints DTC to act as Depositary with respect to the Global Notes.  The Company initially appoints the Trustee to act as Paying Agent and Registrar for the Notes and to act as Custodian with respect to the Global Notes.

(c)                                  As long as the Notes are listed on the Luxembourg Stock Exchange for trading on the Euro MTF Market and the rules of the exchange so require, the Company will also maintain a listing agent, a transfer agent and a paying agent in Luxembourg. The Company initially appoints Banque

34

Internationale à Luxembourg S.A. to act as Luxembourg Listing Agent, Luxembourg Paying Agent and Luxembourg Transfer Agent in Luxembourg for the Notes.

Section 2.04                             Paying Agent to Hold Money in Trust.

The Company shall, no later than 10:00 a.m. (New York City time) on each due date for the payment of principal, premium, if any, and interest on any of the Notes, deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be held in trust for the Holders entitled to the same, and (unless such Paying Agent is the Trustee) the Company shall promptly notify the Trustee of its action or failure so to act.  The Company shall require each Paying Agent other than the Trustee to agree in writing that such Paying Agent shall hold in trust for the benefit of Holders or the Trustee all money held by such Paying Agent for the payment of principal, premium, if any, and 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, a Paying Agent shall have no further liability for the money.  If the Company or a Subsidiary acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent.  Upon any bankruptcy or reorganization proceedings relating to the Company, the Trustee shall serve as Paying Agent for the Notes.

To the extent that the Paying Agent receives any amounts pursuant to this Section 2.04 and such amounts are remitted to the Holders, the Trustee and the Paying Agent shall have no further obligations with respect thereto. Each Holder of a Note or a beneficial interest therein by its acceptance thereof agrees that if any amounts received by it are determined to be in contravention of the provisions of an Intercreditor Agreement it shall hold such funds and pay them to the Security and Intercreditor Agent as described in the Intercreditor Agreements.

Section 2.05                             Holder Lists.

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders in the Note Register.  If the Trustee is not the Registrar, the Company shall furnish to the Trustee at least two Business Days before each Interest Payment Date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders.

Section 2.06                             Transfer and Exchange.

(a)                                 The Notes shall be issued in registered form and shall be transferable only upon the surrender of a Note for registration of transfer and in compliance with Appendix A.

(b)                                 To permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Global Notes and Definitive Notes upon receipt of an Authentication Order in accordance with Section 2.02 or at the Registrar’s request.

(c)                                  No service charge shall be imposed in connection with any registration of transfer or exchange (other than pursuant to Section 2.07), but the Holders shall be required to pay any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.10, 3.06, 3.09, 4.15, 4.16, 4.18 and 9.05).

(d)                                 All Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes shall be the valid obligations of the Company, evidencing

35

the same debt, and entitled to the same benefits under this Indenture, as the Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange.

(e)                                  None of the Company, the Transfer Agent and the Registrar shall be required (1) to issue, to register the transfer of or to exchange any Note 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, (2) to register the transfer of or to exchange any Note so selected for redemption, or tendered for repurchase (and not withdrawn) in connection with a Change of Control Offer or an Asset Sale Offer, in whole or in part, except the unredeemed or unpurchased portion of any Note being redeemed or repurchased in part or (3) to register the transfer of or to exchange any Note between a Record Date and the next succeeding Interest Payment Date.

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

(g)                                  Upon surrender for registration of transfer of any Note at the office or agency of the Company designated pursuant to Section 4.02, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more replacement Notes of any authorized denomination or denominations of a like aggregate principal amount.

(h)                                 At the option of the Holder, Notes may be exchanged for other Notes of any authorized denomination or denominations of a like aggregate principal amount upon surrender of the Notes to be exchanged at the Corporate Trust Office of the Registrar or such other office specified by the Company.  Whenever any Global Notes or Definitive Notes are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the replacement Global Notes and Definitive Notes which the Holder making the exchange is entitled to in accordance with the provisions of Section 2.02 and Appendix A.

(i)                                     All certifications, certificates and Opinions of Counsel required to be submitted to the Registrar pursuant to this Section 2.06 to effect a registration of transfer or exchange may be submitted by mail or by facsimile or electronic transmission (provided that such electronic transmission shall be in the form of a pdf file of a document executed by the required Person).

(j)                                    All transfers and exchanges of any Note shall be subject to the provisions set forth in Appendix A. In addition, the Trustee and the Registrar shall be entitled to receive such evidence as may be reasonably requested by it to establish the identity and/or signatures of any transferee or transferor.

Section 2.07                             Replacement Notes.

If a mutilated Note is surrendered to the Trustee or the Registrar or if a Holder claims that its Note has been lost, destroyed or wrongfully taken and the Trustee and the Registrar receive evidence to its satisfaction of the ownership and loss, destruction or theft of such Note, the Company shall issue and the Trustee, upon receipt of an Authentication Order, shall authenticate a replacement Note if the Trustee’s requirements are otherwise met.  If required by the Trustee or the Company, an indemnity bond must be provided by the Holder that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced.  The Company may charge the Holder for the expenses of the Company, the Trustee and the Registrar in replacing a Note.  Every replacement Note is a contractual obligation of

36

the Company and shall be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder.  Notwithstanding the foregoing provisions of this Section 2.07, in case any mutilated, lost, destroyed or wrongfully taken Note has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Note, pay such Note.

Section 2.08                             Outstanding Notes.

(a)                                 The Notes outstanding at any time are all the Notes authenticated by the Trustee or any authenticating agent 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 2.08 as not outstanding.  Except as set forth in Section 2.09, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note; provided that Notes held by the Company or a Subsidiary of the Company will not be deemed to be outstanding for purposes of Section 3.07(b).

(b)                                 If a Note is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser, as such term is defined in Section 8-303 of the Uniform Commercial Code in effect in the State of New York.

(c)                                  If the principal amount of any Note is considered paid under Section 4.01, it ceases to be outstanding and interest on it ceases to accrue from and after the date of such payment.

(d)                                 If the Trustee or a Paying Agent (other than the Company, a Subsidiary or an Affiliate of any thereof) holds, on the maturity date, any redemption date or any date of purchase pursuant to an Offer to Purchase, money sufficient to pay Notes payable or to be redeemed or purchased on that date and such Paying Agent is not prohibited from paying such money to the Holders on that date pursuant to Article 12, then on and after that date such Notes shall be deemed to be no longer outstanding and shall cease to accrue interest.

Section 2.09                             Treasury Notes.

In determining whether the Holders of the requisite principal amount of Notes have concurred in any direction, waiver or consent, Notes beneficially owned by the Company, or by any Affiliate of 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 a Responsible Officer of the Trustee knows are so owned shall be so disregarded.  Notes so owned which have been pledged in good faith shall not be disregarded if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right to deliver any such direction, waiver or consent with respect to the Notes and that the pledgee is not the Company or any obligor upon the Notes or any Affiliate of the Company or of such other obligor.

Section 2.10                             Temporary Notes.

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

37

Section 2.11                             Cancellation.

The Company at any time may deliver Notes to the Trustee for cancellation.  The Registrar and Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment.  The Trustee or, at the direction of the Trustee, the Registrar or the Paying Agent and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and shall destroy cancelled Notes in accordance with its customary procedures (subject to the record retention requirement of the Exchange Act).  Certification of the destruction of all cancelled Notes shall, upon the written request of the Company, be delivered to the Company.  The Company may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation.

Section 2.12                             Defaulted Interest.

(a)                                 If the Company defaults in a payment of interest on the Notes, it shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01.  The Company shall notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such defaulted interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such defaulted interest as provided in this Section 2.12.  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 ten days prior to the related payment date for such defaulted interest.  The Company shall promptly notify the Trustee of such special record date.  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 deliver by electronic transmission in accordance with the applicable procedures of the Depositary, or cause to be mailed or delivered by electronic transmission in accordance with the applicable procedures of the Depositary to each Holder a notice that states the special record date, the related payment date and the amount of such interest to be paid.

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

Section 2.13                             CUSIP and ISIN Numbers

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

38

Section 3.02                             Selection of Notes to Be Redeemed or Purchased.

(a)                                 If less than all of the Notes are to be redeemed pursuant to Section 3.07 or purchased in an Offer to Purchase at any time, the selection of the Notes to be redeemed or purchased shall be made as follows: (1) if the Notes are listed on any national securities exchange and the Paying Agent is notified of such listing, in compliance with the requirements of the principal national securities exchange on which the Notes are listed or (2) if such national securities exchange has no requirement governing redemptions or if the Notes are not so listed, the Depositary shall select the Notes by lot in the case of Global Notes and otherwise on a pro rata basis, by lot or by such other method as the Paying Agent in its sole discretion deems to be fair and appropriate.  In the event of partial redemption or purchase by lot, the particular Notes to be redeemed or purchased shall be selected, unless otherwise provided herein, not less than 30 (or 15 days in the case of Section 3.07(g)) nor more than 60 days prior to the redemption date by the Trustee from the then outstanding Notes not previously called for redemption or purchase.

(b)                                 The Trustee shall promptly notify the Company in writing of the Notes selected for redemption or purchase and, in the case of any Note selected for partial redemption or purchase, the principal amount thereof to be redeemed or purchased.  Notes and portions of Notes selected shall be in amounts of $1,000 or integral multiples of $1,000; provided that no Notes of $200,000 in principal amount or less shall be redeemed in part.  Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption or purchase also apply to portions of Notes called for redemption or purchase.

(c)                                  After the redemption date or purchase date, upon surrender of a Note to be redeemed or purchased in part only, a new Note or Notes in principal amount equal to the unredeemed or unpurchased portion of the original Note, representing the same Debt to the extent not redeemed or not purchased, shall be issued in the name of the Holder of the Notes upon cancellation of the original Note (or appropriate book entries shall be made to reflect such partial redemption).

Section 3.03                             Notice of Redemption.

(a)                                 Subject to Section 3.09, the Company shall mail or deliver by electronic transmission in accordance with the applicable procedures of the Depositary, or cause to be mailed (or delivered by electronic transmission in accordance with the applicable procedures of the Depositary) notices of redemption of Notes not less than 30 days (or 15 days in the case of Section 3.07(g)) but not more than 60 days before the redemption date to each Holder whose Notes are to be redeemed pursuant to this Article at such Holder’s registered address or otherwise in accordance with the applicable procedures of the Depositary, except that redemption notices may be mailed more than 60 days prior to a redemption

39

date if the notice is issued in connection with Article 8 or Article 13.  Except as set forth in Section 3.07(f), notices of redemption may not be conditional.

(b)                                 The notice shall identify the Notes to be redeemed (including CUSIP and ISIN number, if applicable) and shall state:

(1)                                 the redemption date;

(2)                                 the redemption price, including the portion thereof representing any accrued and unpaid interest; provided that in connection with a redemption under Section 3.07(a), the notice need not set forth the redemption price but only the manner of calculation thereof;

(3)                                 if any Note is to be redeemed in part only, the portion of the principal amount of that Note that is to be redeemed;

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

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

(6)                                 that, unless the Company defaults in making such redemption payment or the Paying Agent is prohibited from making such payment pursuant to the terms of this Indenture, interest on Notes called for redemption ceases to accrue on and after the redemption date;

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

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

(9)                                 if applicable, any condition to such redemption.

(c)                                  At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at the Company’s expense; provided that the Company shall have delivered to the Trustee, at least 45 days before notice of redemption is required to be sent or caused to be sent to Holders pursuant to this Section 3.03 (unless a shorter notice shall be agreed to by the Trustee), an Officer’s Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in Section 3.03(b).

(d)                                 From and after the date the Notes are listed on the Luxembourg Stock Exchange for trading on the Euro MTF Market and so long as it is required by the rules of such exchange, the Company shall publish notice of redemption as described in Section 14.02(d).

Section 3.04                             Effect of Notice of Redemption.

Once notice of redemption is given in accordance with Section 3.03, Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price (except as provided for in Section 3.07(f)).  The notice, if mailed or delivered by electronic transmission in a manner herein provided, shall be conclusively presumed to have been given, whether or not the Holder receives such notice.  In any case, failure to give such notice or any defect in the notice to the Holder of any Note designated for redemption in whole or in part shall not affect the validity of the proceedings for the redemption of any other Note.  Subject to Section 3.05, on and after the redemption date, interest ceases to accrue on Notes or portions of Notes called for redemption.

40

Section 3.05                             Deposit of Redemption or Purchase Price.

(a)                                 No later than 10:00 a.m. (New York City time) on the redemption or purchase date, the Company shall deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase price of and accrued and unpaid interest on all Notes to be redeemed or purchased on that date.  If a Note is redeemed or purchased on or after a Record Date but on or prior to the related Interest Payment Date, then any accrued and unpaid interest shall be paid to the Holder of record on such Record Date.  The Paying Agent shall promptly send to each Holder whose Notes are to be redeemed or repurchased the applicable redemption or purchase price thereof and accrued and unpaid interest thereon via wire transfer of immediately available funds to the accounts specified by such Holders thereof.  The Trustee or the Paying Agent shall promptly return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption or purchase price of, and accrued and unpaid interest on, all Notes to be redeemed or purchased.

(b)                                 If the Company complies with the provisions of Section 3.05(a), on and after the redemption or purchase date, interest shall cease to accrue on the Notes or the portions of Notes called for redemption or purchase.  If a Note is redeemed or purchased on or after a Record Date but on or prior to the related Interest Payment Date, then any accrued and unpaid interest to the redemption or purchase date in respect of such Note will be paid on such redemption or purchase date to the Person in whose name such Note is registered at the close of business on such Record Date.  If any Note called for redemption or purchase shall not be so paid upon surrender for redemption or purchase because of the failure of the Company to comply with Section 3.05(a), interest shall be paid on the unpaid principal, from the redemption or purchase date until such principal is paid, and, to the extent lawful, on any interest accrued to the redemption or purchase date not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01.

Section 3.06                             Notes Redeemed or Purchased in Part.

Upon surrender of a Note that is redeemed or purchased in part, the Company shall issue and, upon receipt of an Authentication Order, the Trustee shall promptly authenticate and mail to the Holder (or make appropriate adjustments to the amount and beneficial interests in any Global Note) at the expense of the Company a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered representing the same Debt to the extent not redeemed or purchased; provided that each new Note shall be in a principal amount of $200,000 or an integral multiple of $1,000 in excess thereof.  It is understood that, notwithstanding anything in this Indenture to the contrary, only an Authentication Order and not an Opinion of Counsel or Officer’s Certificate is required for the Trustee to authenticate such new Note.

Section 3.07                             Optional Redemption.

(a)                                 At any time prior to August 1, 2017 , the Company may on any one or more occasions redeem the Notes, at its option, in whole or in part, upon notice pursuant to Section 3.03 at a redemption price as calculated by the Company equal to 100% of the outstanding principal amount of such Notes, plus the Applicable Premium.  Promptly after the determination thereof, the Company shall give the Trustee notice of the redemption price provided for in this Section 3.07(a), and the Trustee shall not be responsible for such calculation.

(b)                                 On or prior to August 1, 2017, the Company may on any one or more occasions, at its option, use an amount not to exceed the net cash proceeds of one or more Eligible Equity Offerings to redeem up to 35% of the aggregate principal amount of the outstanding Notes (including any Additional Notes) with the Net Cash Proceeds of one or more Eligible Equity Offerings, upon notice pursuant to Section 3.03, at a redemption price as calculated by the Company equal to 107.875% of the

41

principal amount of the Notes redeemed, plus accrued and unpaid interest and Additional Amounts, if any, to, but excluding the redemption date; provided that (1) after giving effect to any such redemption,  at least 65% of the aggregate principal amount of the Notes (including any Additional Notes but excluding Notes held by the Company and its Subsidiaries) issued under this Indenture remains outstanding; and (2) the Company makes such redemption not more than 180 days after the consummation of such Eligible Equity Offering.

(c)                                  Except pursuant to clauses (a), (b), (g) or (h) of this Section 3.07, the Notes shall not be redeemable at the Company’s option prior to August 1, 2017.

(d)                                 On and after August 1, 2017, the Company may on any one or more occasions redeem the Notes, at its option, in whole or in part, upon notice pursuant to Section 3.03 at the redemption prices as calculated by the Company (expressed as a percentage of outstanding principal amount of the Notes to be redeemed) set forth below, plus accrued and unpaid interest and Additional Amounts, if any, to, but excluding, the redemption date (subject to the right of Holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date), if redeemed during the 12-month period commencing on August 1 of the years set forth below::

(e)                                  Any redemption pursuant to this Section 3.07 shall be made pursuant to the provisions of Sections 3.01 through 3.06.

(f)                                   Notice of any redemption of the Notes in connection with a corporate transaction (including an Eligible Equity Offering, an Incurrence of Debt or a Change of Control Triggering Event) may, at the Company’s discretion, be given prior to the completion thereof and any such redemption or notice may, at the Company’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion of the related transaction. If such redemption or purchase is so subject to satisfaction of one or more conditions precedent, such notice shall describe each such condition, and if applicable, shall state that, in the Company’s discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption or purchase may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the redemption date, or by the redemption date as so delayed. In addition, the Company may designate at its option and provide in such notice that payment of the redemption price and performance of the Company’s obligations with respect to such redemption may be performed by another Person; provided that any call for redemption by such Person be treated as if such call was made by the Company.

(g)                                  In connection with any tender offer for the Notes, in the event that the Holders of not less than 90% of the aggregate principal amount of the outstanding Notes validly tender and do not withdraw such Notes in such tender offer and the Company, or a third party making such a tender offer in lieu of the Company, purchases all the Notes validly tendered and not withdrawn by such Holders, the Company or any such third party will have the right, on not less than 15 nor more than 60 days’ prior notice, given not more than 30 days following the such purchase date, to redeem all of the Notes that remain outstanding following such purchase at the purchase price equal to that offered to each other Holder in such tender offer plus, to the extent not included in the tender offer payment, accrued and unpaid interest and Additional Amounts, if any, on the Notes that remain outstanding, to the date of redemption (subject to the right of Holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date).

(h)                                 (1) At any time, if the Company or any successor is or, on the next date on which any amount would be payable in respect of the Notes, would be required to pay Additional Amounts on the Notes, or any Guarantor or any successor is required to pay Additional Amounts on the Note Guarantees, the Company or any successor may elect to redeem the Notes, in whole but not in part, at a redemption price as calculated by the Company equal to 100% of the remaining principal amount plus accrued and unpaid interest, if any, and any Additional Amounts accrued to the fixed date of redemption. The Company or any successor will not be entitled to redeem the Notes pursuant to the previous sentence unless the Company, a Guarantor or any successor is required to pay such Additional Amounts due to a change in or amendment to the laws (or any rules or regulations thereunder) of the jurisdiction of its incorporation or any political subdivision or taxing authority thereof or therein, including a change in or amendment to an official interpretation, administration or application of such laws, rules, or regulations (including a holding by a court of competent jurisdiction), which change or amendment becomes effective or is announced on or after the Issue Date of the Notes or, in the event a successor which is not incorporated pursuant to the laws of Bermuda has assumed the obligations under the Notes, on or after the date a successor assumes the obligations under the Notes.

(2)                           In the event that the Company or any successor elects to redeem the Notes pursuant to clause (h)(1) above, it will deliver to the Trustee and the Paying Agent: (1) an Officer’s Certificate, signed in the name of the Company or any successor, stating that (a) the Company or such successor is entitled to redeem the Notes pursuant to the terms of this Indenture and the Notes and certifying that the condition or conditions precedent to the right of the Company or any successor to so redeem have occurred or been satisfied and (b) the payment of Additional Amounts cannot be avoided by the relevant payor taking reasonable measures available to it; provided, however, that reasonable measures shall not include changing the payor’s jurisdiction of incorporation or the location of its principal executive office or registered office; and (2) an opinion of tax counsel of nationally recognized standing in the Relevant Taxing Jurisdiction, to the effect that the Company, a Guarantor or any successor has or will become obligated to pay Additional Amounts as a result of the change or amendment described in the preceding paragraph, and that all governmental requirements necessary for the Company or any successor to effect the redemption have been complied with.

Section 3.08                             Mandatory Redemption; Open Market Purchases.

The Company will not be required to make mandatory redemption or sinking fund payments with respect to the Notes.

The Company or its Affiliates may at any time purchase Notes in the open market or otherwise at any price. Any such purchased Notes will not be resold, except in compliance with applicable requirements or exemptions under the relevant securities laws.

Section 3.09                             Offers to Repurchase by Application of Excess Proceeds.

(a)                                 In the event that, pursuant to Section 4.16, the Company is required to commence an Asset Sale Offer, the Company must, within 30 days, make such Asset Sale Offer to purchase Notes having a principal amount equal to:

(A) accumulated Excess Proceeds, multiplied by

(B) a fraction (x) the numerator of which is equal to the outstanding principal amount of the Notes and (y) the denominator of which is equal to the outstanding aggregate principal amount of the Notes and all other Parity Lien Debt that is similarly required to be

43

repaid, redeemed or tendered for in connection with the Asset Sale, rounded down to the nearest U.S.$1,000.

The purchase price for the Notes will be 100% of the outstanding principal amount plus accrued and unpaid interest and Additional Amounts, if any, to the date of purchase. If the Offer to Purchase is for less than all of the outstanding Notes and Notes in an aggregate principal amount in excess of the purchase amount are tendered and not withdrawn pursuant to the offer, the Company will purchase Notes having an aggregate principal amount equal to the purchase amount on a pro rata basis, with adjustments so that only Notes in multiples of U.S.$1,000 principal amount will be purchased; provided that after a purchase from a holder in part, such holder shall hold U.S.$200,000 in principal amount of notes or a multiple of U.S.$1,000 in excess thereof.

(b)                                 The Asset Sale Offer will remain open for a period of 20 Business Days following its commencement, except to the extent that a longer period is required by applicable law (the “Asset Sale Offer Period”).  No later than 30 Business Days after the termination of the Asset Sale Offer Period (the “Asset Sale Purchase Date”), the Company will apply all Excess Proceeds to the purchase of the aggregate principal amount of Notes and, if applicable, Parity Lien Debt (on a pro rata basis, if applicable) required to be purchased pursuant to Section 4.16 (the “Asset Sale Offer Amount”), or, if less than the Asset Sale Offer Amount of Notes (and, if applicable, Parity Lien Debt) has been so validly tendered, all Notes and Parity Lien Debt validly tendered in response to the Asset Sale Offer.  Payment for any Notes so purchased will be made in the same manner as interest payments on the Notes are made.

(c)                                  If the Asset Sale Purchase Date is on or after a Record Date and on or before the related Interest Payment Date, any accrued, unpaid interest and Additional Amounts, if any, up to but excluding the Asset Sale Purchase Date, shall be paid to the Person in whose name a Note is registered at the close of business on such Record Date.

(d)                                 Upon the commencement of an Asset Sale Offer, the Company shall mail a notice to each of the Holders or otherwise deliver such notice in accordance with the applicable procedures of the Depositary, with a copy to the Trustee.  The notice shall contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer.  The Asset Sale Offer shall be made to all Holders and, if required, all holders of Parity Lien Debt.  The notice, which shall govern the terms of the Asset Sale Offer, shall state:

(1)                                 that an Asset Sale Offer is being made pursuant to this Section 3.09 and Section 4.16 and the expiration time of the Asset Sale Period;

(2)                                 the Asset Sale Offer Amount, the purchase price, including the portion thereof representing any accrued and unpaid interest, and the Asset Sale Purchase Date;

(3)                                 that Notes must be tendered in integral multiples of $1,000 (subject to clause (8) below), and any Note not properly tendered will remain outstanding and will continue to accrue interest;

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

(5)                                 that Holders electing to have a Note purchased pursuant to any Asset Sale Offer shall be required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” attached to such Note completed, the Paying Agent specified in the notice at the

44

address specified in the notice prior to the close of business on the third Business Day preceding the Asset Sale Purchase Date;

(6)                                 that Holders shall be entitled to withdraw their election if the Company, the Depositary or the Paying Agent, as the case may be, receives at the address specified in the notice, not later than the expiration of the Asset Sale Offer Period, a telegram, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Notes the Holder tendered for purchase and a statement that such Holder is withdrawing its tendered Notes and its election to have such Note purchased;

(7)                                 that, if the aggregate principal amount of Notes and Parity Lien Debt surrendered by the holders thereof exceeds the Asset Sale Offer Amount, then the Notes and such Parity Lien Debt will be purchased on a pro rata basis based on the aggregate accreted value or principal amount, as applicable, of the Notes or such Parity Lien Debt tendered and the selection of the Notes for purchase shall be made as follows: (1) if the Notes are listed on any national securities exchange and the Paying Agent is notified of such listing, in compliance with the requirements of the principal national securities exchange on which the Notes are listed or (2) if such national securities exchange has no requirement governing redemptions or if the Notes are not so listed, the Depositary shall select the Notes by lot in the case of Global Notes and otherwise on a pro rata basis, by lot or by such other method as the Paying Agent in its sole discretion deems to be fair and appropriate, although no Note having a principal amount of $200,000 shall be purchased in part;

(8)                                 that Holders whose Notes were purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (the unpurchased portion of the Notes must be equal to $200,000 or an integral multiple of $1,000 in excess thereof); and

(9)                                 the other procedures, as determined by the Company, consistent with this Section 3.09 that a Holder must follow.

(e)                                  On or before the Asset Sale Purchase Date, the Company will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary or as otherwise provided in Section 4.16(a)(5), the Asset Sale Offer Amount of Notes and Parity Lien Debt or portions thereof validly tendered and not properly withdrawn pursuant to the Asset Sale Offer, or, if less than the Asset Sale Offer Amount has been validly tendered and not properly withdrawn, all Notes and Parity Lien Debt so tendered, in the case of the Notes, in whole number multiples of $1,000; provided that if, following repurchase of a portion of a Note, the remaining principal amount of such Note outstanding immediately after such repurchase would be less than $200,000, then the portion of such Note so repurchased shall be reduced so that the remaining principal amount of such Note outstanding immediately after such repurchase is $200,000.  The Company will deliver, or cause to be delivered, to the Trustee the Notes so accepted and an Officer’s Certificate stating the aggregate principal amount of Notes or portions thereof so accepted and that such Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 3.09..

(f)                                   The Trustee, the Paying Agent or the Company, as the case may be, will promptly, but in no event later than five Business Days after termination of the Asset Sale Offer Period, distribute to each tendering Holder or holder or lender of Parity Lien Debt, as the case may be, an amount equal to the purchase price of the Notes or the Parity Lien Debt so validly tendered and not properly withdrawn by such holder or lender, as the case may be, and accepted by the Company for purchase, and the Company will promptly issue a new Note, and the Trustee, upon receipt of an Authentication Order, will authenticate and mail or deliver (or cause to be transferred by book-entry) such new Note to such

45

Holder (it being understood that, notwithstanding anything in this Indenture to the contrary, no Opinion of Counsel or Officer’s Certificate is required for the Trustee to authenticate and mail or deliver such new Note) in a principal amount equal to any unpurchased portion of the Note surrendered; provided that each such new Note will be in a principal amount of $200,000 or an integral multiple of $1,000 in excess thereof.  Any Note not so accepted will be promptly mailed or delivered by the Company to the Holder thereof.  The Company will announce the results of the Asset Sale Offer on or as soon as practicable after the Asset Sale Purchase Date.

(g)                                  The Company will comply with Rule 14e-1 under the Exchange Act (to the extent applicable) and all other applicable laws or regulations in connection with the repurchase of Notes pursuant to an Asset Sale Offer, and the procedures related to an Asset Sale Offer contained in this Indenture will be modified as necessary to permit such compliance.  To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Indenture, the Company will comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Indenture by virtue thereof.

Section 4.06                             Reporting Requirements.

(a)                                 Whether or not required by the SEC, so long as any Notes are outstanding, the Company will file with the SEC for public availability within the time periods specified in the SEC’s rules and regulations taking into account any extension of time, deemed filing date or safe harbor contemplated or provided for by Rule 12b-25, Rule 13a-11(c), and Rule 15d-11(c) under the Exchange Act, or General Instruction I.A.3(b) of Form S-3 under the Securities Act, and successor provisions (unless the SEC will not accept such a filing, in which case the Company will furnish to the Trustee and, upon its prior request, to any Holder, within the time periods specified in the SEC’s rules and regulations):

(B)                               the new Debt does not have a Stated Maturity prior to (i) the Stated Maturity of the Debt to be refinanced, and the Average Life of the new Debt is at least equal to the remaining Average Life of the Debt to be refinanced or (ii) the 91st day after

(21)                    Debt of the Company or a Restricted Subsidiary consisting of Capitalized Lease Obligations and Purchase Money Obligations; provided, however, that the aggregate principal amount of such Debt, and any refinancing thereof, does not exceed in an aggregate

55

principal amount at any one time outstanding the greater of (i) $150.0 million and (ii) 3.0% of Adjusted Consolidated Net Tangible Assets; provided, further, that such Debt exists at the date of such purchase, lease or improvement, or is created within 365 days thereafter (for the avoidance of doubt, the purchase date for any asset shall be the later of the date of completion of construction or installation and the beginning of the full productive use of such asset).

(c)                                  Notwithstanding anything to the contrary in this Section 4.09, the maximum amount of Debt that the Company and its Restricted Subsidiaries may Incur pursuant to this Section 4.09 shall not be deemed to be exceeded, with respect to any outstanding Debt, solely as a result of fluctuations in the exchange rate of currencies.

(d)                                 For purposes of determining compliance with this Section 4.09, in the event that any proposed Debt meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (21) of Section 4.09(b), or is entitled to be Incurred pursuant to Section 4.09(a), the Company and its Restricted Subsidiaries will be permitted to classify such item of Debt at the time of its Incurrence in any manner that complies with this Section 4.09 or to later reclassify all or a portion of such item of Debt. Any Permitted Refinancing Debt and any Debt permitted to be Incurred under this Indenture to refinance Debt Incurred pursuant to clauses (2), (3), (4), (6), (7), (15), (18), (19), (20) and (21) of Section 4.09(b) shall be deemed to include additional Debt Incurred to pay premiums (including tender premiums), discounts, fees and other costs and expenses (including original issue discount, upfront fees or similar fees) in connection with such refinancing.

(e)                                  The Company may not Incur any Debt that is subordinate in right of payment to other Debt of the Company unless such Debt is also subordinate in right of payment to the Notes or the relevant guarantee on substantially identical terms; provided, however, that no Debt will be deemed to be subordinated in right of payment to any other Debt of the Company solely by virtue of being unsecured, by virtue of being secured with different collateral or by virtue of being secured on a junior priority basis or by virtue of the applicability of waterfall or other payment ordering provisions affecting different tranches of Debt.

(f)                                   The accrual of interest, the accretion or amortization of original issue discount, the payment of regularly scheduled interest in the form of additional Debt of the same instrument or the payment of regularly scheduled dividends on Disqualified Stock in the form of additional Disqualified Stock with the same terms will not be deemed to be an Incurrence of Debt for purposes of this Section 4.09; provided that any such outstanding additional Debt paid in respect of Debt Incurred pursuant to any provision of clause (b) above will be counted as Debt outstanding for purposes of any future Incurrence of Debt pursuant to Section 4.09(a).

(g)                                  For purposes of determining compliance with any U.S. dollar-denominated restriction on the Incurrence of Debt, the U.S. dollar-equivalent principal amount of Debt denominated in a non-U.S. currency will be calculated based on the relevant currency exchange rate in effect on the date such Debt was Incurred or, in the case of revolving credit Debt, first committed; provided that if such Debt is Incurred to refinance other Debt denominated in a non-U.S. currency, and such refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction will be deemed not to have been exceeded so long as the principal amount of such Permitted Refinancing Debt does not exceed the principal amount of such Debt being refinanced. The principal amount of any Debt Incurred to refinance other Debt, if Incurred in a different currency from the Debt being refinanced, will be calculated based on the currency exchange rate applicable to the currencies in which such Permitted Refinancing Debt is denominated that is in effect on the date of such refinancing.

Section 4.15                             Offer to Repurchase Upon Change of Control Triggering Event.

(a)                                 If a Change of Control Triggering Event occurs, unless the Company has exercised its right to redeem all of the Notes pursuant to Sections 3.03 and 3.07, the Company will make an offer to purchase all of the Notes (the “Change of Control Offer”) at a purchase price in cash equal to 101% of the principal amount of the Notes plus accrued and unpaid interest and Additional Amounts, if any, to, but excluding the date of purchase (the “Change of Control Payment”), subject to the right of Holders of record on a Record Date to receive any interest due on the Change of Control Payment Date. Within 15 days following any Change of Control Triggering Event, unless the Company has exercised its right to redeem all of the Notes pursuant to Sections 3.03 and 3.07, the Company will mail a notice of such Change of Control Offer to each Holder or otherwise deliver notice in accordance with the applicable procedures of the Depositary, with a copy to the Trustee, stating:

(1)                                 that a Change of Control Offer is being made pursuant to this Section 4.15, the expiration time for such Change of Control Offer (which shall be no earlier than 15 days nor later than 60 days from the date such notice is mailed or otherwise delivered in accordance with the applicable procedures of the Depositary) and that all Notes properly tendered pursuant to such Change of Control Offer will be accepted for purchase by the Company at a purchase price in cash equal to 101% of the principal amount of such Notes plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of Holders of record on the applicable Record Date to receive interest due on the Change of Control Payment Date);

(2)                                 the purchase date (which shall be no later than five Business Days after the date such Change of Control Offer expires) (the “Change of Control Payment Date”);

(3)                                 that Notes must be tendered in integral multiples of $1,000, and any Note not properly tendered will remain outstanding and continue to accrue interest (subject to clause (7) below);

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

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

(6)                                 that Holders shall be entitled to withdraw their tendered Notes and their election to require the Company to purchase such Notes; provided that the Paying Agent receives at the address specified in the notice, not later than the expiration time of such Change of Control Offer,

65

a telegram, facsimile transmission or letter setting forth the name of the Holder of the Notes, the principal amount of Notes tendered for purchase and a statement that such Holder is withdrawing its tendered Notes and its election to have such Notes purchased;

(7)                                 that, if a Holder is tendering less than all of its Notes, such Holder will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (the unpurchased portion of the Notes must be equal to $200,000 or an integral multiple of $1,000 in excess thereof); and

(8)                                 the other procedures, as determined by the Company, consistent with this Section 4.15 that a Holder must follow.

The notice, if mailed or otherwise delivered in a manner herein provided, shall be conclusively presumed to have been given, whether or not the Holder receives such notice.  If (A) the notice is mailed in a manner herein provided and (B) any Holder fails to receive such notice or a Holder receives such notice but it is defective, such Holder’s failure to receive such notice or such defect shall not affect the validity of the proceedings for the purchase of the Notes as to all other Holders that properly received such notice without defect.

(b)                                 On the Change of Control Payment Date, the Company will, to the extent lawful:

(1)                                 accept for payment all Notes or portions of Notes (in integral multiples of $1,000)  properly tendered pursuant to the Change of Control Offer;  provided that if, following repurchase of a portion of a Note, the remaining principal amount of such Note outstanding immediately after such repurchase would be less than $200,000, then the portion of such Note so repurchased shall be reduced so that the remaining principal amount of such Note outstanding immediately after such repurchase is $200,000;

(2)                                 deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes so tendered; and

(3)                                 deliver or cause to be delivered to the Trustee for cancellation the Notes so accepted together with an Officer’s Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company in accordance with this Section 4.15.

(c)                                  The Paying Agent will promptly mail (or otherwise deliver in accordance with the applicable procedures of the Depositary) to each Holder of Notes so tendered the Change of Control Payment for such Notes, and the Trustee will promptly authenticate and mail (or otherwise deliver in accordance with the applicable procedures of the Depositary) (or make appropriate adjustments to the amount and beneficial interests in any Global Note) to each Holder a new Note (it being understood that, notwithstanding anything in this Indenture to the contrary, no Opinion of Counsel or Officer’s Certificate will be required for the Trustee to authenticate and mail or deliver such new Note) equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each such new Note will be in a principal amount of $200,000 or integral multiples of $1,000 in excess thereof.

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

(e)                                  Prior to making a Change of Control Payment, and as a condition to such payment (1) the requisite lenders or holders of Debt incurred or issued under a credit facility, an indenture

66

or other agreement that may be violated by such payment shall have consented to such Change of Control Payment being made and waived the event of default, if any, caused by the Change of Control Triggering Event or (2) the Company will repay all outstanding Debt incurred or issued under a credit facility, an indenture or other agreement that may be violated by a Change of Control Payment or the Company will offer to repay all such Debt, make payment to the lenders or holders of such Debt that accept such offer and obtain waivers of any event of default arising under the relevant credit facility, indenture or other agreement from the remaining lenders or holders of such Debt.  The Company covenants to effect such repayment or obtain such consent prior to making a Change of Control Payment, it being a default of the Change of Control Triggering Event provisions of this Indenture if the Company fails to comply with such covenant.

(f)                                   the Company will not be required to make an Change of Control Offer upon a Change of Control Triggering Event if (1) a third party makes the Change of Control Offer upon a Change of Control Triggering Event in the manner, at the time and otherwise in compliance with the requirements set forth in the Indenture applicable to a Change of Control Offer upon a Change of Control Triggering Event made by the Company and purchases all the notes properly tendered and not withdrawn under such Change of Control Offer or (2) notice of redemption has been given pursuant to this Indenture as described under ARTICLE 3 unless and until there is a default in payment of the applicable redemption price.

(g)                                  Notwithstanding anything to the contrary herein, a Change of Control Offer may be made in advance of a Change of Control Triggering Event and be conditional upon such Change of Control Triggering Event if a definitive agreement is in place for the Change of Control at the time of making of the Change of Control Offer.

(h)                                 In the event that the Holders of not less than 90% of the aggregate principal amount of the outstanding Notes accept an Change of Control Offer and the Company or a third party purchases all the Notes held by such Holders, the Company will have the right, on not less than 15 nor more than 60 days’ prior notice, given not more than 30 days following the purchase pursuant to the Change of Control Offer, to redeem all of the Notes that remain outstanding following such purchase at the Change of Control Payment equal to that in the Change of Control Offer plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest and Additional Amounts, if any, on the Notes that remain outstanding, to the date of redemption (subject to the right of Holders of record on the relevant Change of Control Payment Date to receive interest due on the relevant Interest Payment Date).

(i)                                     The Company will comply with Rule 14e-1 under the Exchange Act (to the extent applicable) and all other applicable laws and regulations in connection with the repurchase of the Notes pursuant to an Change of Control Offer, and the above procedures will be deemed modified as necessary to permit such compliance. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Indenture, the Company will comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations described in this Indenture by virtue thereof.

(j)                                    Other than as specifically provided in this Section 4.15, any purchase pursuant to this Section 4.15 shall be made pursuant to the provisions of Sections 3.02, 3.05 and 3.06.

Section 4.16                             Limitation on Asset Sales.

(a)                                 The Company will not, and will not permit any Restricted Subsidiary to, make or any Asset Sale, unless the following conditions are met:

67

(1)                           The Asset Sale is for Fair Market Value.

(2)                            At least 75% of the consideration for such Asset Sale, together with all other Asset Sales since the Issue Date (on a cumulative basis), consists of cash or Cash Equivalents received at closing; provided, however, to the extent that any disposition in any such Asset Sale was of Collateral, the consideration other than cash or Cash Equivalents is pledged as Collateral under the Security Documents substantially simultaneously with such sale, in accordance with the requirements set forth in this Indenture.

For purposes of this clause (2), (i) the assumption by the purchasers of Debt or other obligations (other than Subordinated Debt) of the Company or a Restricted Subsidiary pursuant to a written agreement which releases or indemnifies the Company or such Restricted Subsidiary from such obligations, (ii) Debt (other than Subordinated Debt) of any Restricted Subsidiary that is no longer a Restricted Subsidiary as a result of such Asset Sale, to the extent that the Company and each other Restricted Subsidiary are released from any guarantee of, or are not liable with respect to, such Debt in connection with such Asset Sale, (iii) consideration consisting of Debt of the Company or any Guarantor received from persons who are not the Company or any Restricted Subsidiary, (iv) instruments, securities or other obligations received by the Company or any of its Restricted Subsidiaries from the purchasers that are converted into cash or Cash Equivalents within 180 days of the closing, and (v) any Designated Non-cash Consideration received by the Company or such Restricted Subsidiary in such Asset Sale having an aggregate Fair Market Value, taken together with all other Designated Non-cash Consideration received pursuant to this clause (v) that is at that time outstanding, not to exceed the greater of (A) $225.0 million and (B) 5.0% of Adjusted Consolidated Net Tangible Assets at the time of the receipt of such Designated Non-cash Consideration, with the Fair Market Value of each item of Designated Non-cash Consideration being measured at the time received and without giving effect to subsequent changes in value, shall be considered to be cash received at closing.

(3)                           Within 365 days after the receipt of any Net Cash Proceeds from an Asset Sale, the Net Cash Proceeds may be used:

(A)                               to the extent the disposition was of Collateral, to either (A) reduce Debt under the Notes on a ratable basis, at its option by (i) redeeming Notes as described under Section 3.07 or (ii) purchasing Notes through open market purchases, or (B) purchase the Notes (including any Additional Notes) pursuant to an offer to all holders of Notes at a purchase price equal to 100% of the outstanding principal amount thereof, plus accrued and unpaid interest and Additional Amounts, if any, to, but not including the date of purchase, and in each case any other Parity Lien Debt on a ratable basis;

(B)                               to the extent the disposition was not of Collateral, to repay Debt (other than Subordinated Debt) of the Company or any Restricted Subsidiary (and in the case of a revolving credit, permanently reduce the commitment thereunder by such amount), in each case owing to a Person other than the Company or any Restricted Subsidiary;

(C)                               to acquire or invest in (or within such 365-day period in this clause (3), the Board of Directors shall have made a good faith determination to acquire or invest, which acquisition or investment shall be consummated on or prior to 180 days of such determination) (i) Additional Assets, (ii) assets of a Permitted Business (or make capital expenditures in respect of a Permitted Business), (iii) a majority of the Voting Stock of another Person that thereupon becomes a Restricted Subsidiary engaged in a Permitted Business or (iv) a Permitted Business Investment; provided, however, that such assets

68

acquired with the Net Cash Proceeds of any disposition in any such Asset Sale of Collateral are pledged as Collateral under the Security Documents substantially simultaneously with such acquisition, in accordance with the requirements set forth in this Indenture; or

(D)                               to make a Restricted Payment pursuant to Section 4.08(b)(16) to the extent of the limitation on the amount of such Restricted Payment set forth therein.

(4)                           Notwithstanding clauses (2) and (3) above, the Company and its Restricted Subsidiaries will be permitted to consummate an Asset Sale without complying with such clauses to the extent either (A) at least 75% of the consideration for such Asset Sale constitutes Additional Assets, cash, Cash Equivalents and/or Marketable Securities or (B) in the event of an Asset Sale involving Equity Interests of a Restricted Subsidiary, (i) at least 30% of the consideration for such Asset Sale constitutes Additional Assets, cash, Cash Equivalents and/or Marketable Securities received at closing; provided that the remaining 45% of the consideration is paid on or prior to the third anniversary of the closing and constitutes Additional Assets, cash, Cash Equivalents and/or Marketable Securities and (ii) in the event existing Equity Interests are sold by the Company that such Equity Interests are pledged in favor of the Company or Restricted Subsidiary (or such Equity Interests are mortgaged for the benefit of the Company or Restricted Subsidiary) until such consideration is paid; provided that any consideration not constituting Additional Assets received by the Company or any Restricted Subsidiary in connection with any Asset Sale permitted to be consummated under this clause shall be applied (in the case of cash, Cash Equivalents and Marketable Securities within 365 days after the receipt thereof subject to the proviso above) in accordance with the provisions of clause (3) above; and provided, further, that such Additional Assets acquired through any disposition of Collateral are pledged as Collateral under the Security Documents substantially simultaneously with such acquisition, in accordance with the requirements set forth in this Indenture.

(5)                           The Net Cash Proceeds of an Asset Sale not applied pursuant to Section 4.16(a)(3)  or determined by the Board of Directors to not be applied pursuant to Section 4.16(a)(3)(C) within 365 days of the Asset Sale constitute “Excess Proceeds.” Excess Proceeds of less than U.S.$50.0 million will be carried forward and accumulated. When accumulated Excess Proceeds equals or exceeds such amount, the Company must, within 30 days, make an offer (“Asset Sale Offer”) to purchase Notes pursuant to Section 3.09. Upon completion of an Asset Sale Offer, Excess Proceeds will be reset at zero.

(b)                                 Pending application in accordance with this Section 4.16, Net Cash Proceeds may be applied to temporarily reduce revolving credit borrowings, if any, or invested in Cash Equivalents. The Fair Market Value for any Asset Sale will be determined by the Company in good faith.

(c)                                  To the extent that any portion of Net Cash Proceeds payable in respect of the Notes is denominated in a currency other than U.S. dollars, the amount thereof payable in respect of the Notes shall not exceed the net amount of funds in U.S. dollars that is actually received by the Company upon converting such portion into U.S. dollars.

(d)                                 Notwithstanding any other provisions of this Section 4.16, (i) to the extent that any of or all the Net Cash Proceeds of any Asset Sales is prohibited or delayed by applicable law, the portion of such Net Cash Proceeds so affected will not be required to be applied in compliance with this covenant, and such amounts may be retained by the Company or Subsidiary, as applicable, so long, but only so long, as the applicable law will not permit repatriation to the United States, Bermuda or the Cayman Islands (the Company hereby agreeing to use reasonable efforts (as determined in the Company’s

69

good faith judgment) to, or otherwise cause the applicable Subsidiary to, promptly take all actions reasonably required by the applicable law to permit such repatriation), and once such repatriation of any of such affected Net Cash Proceeds is permitted under the applicable law, such repatriation will be promptly effected and such repatriated Net Cash Proceeds will be promptly (and in any event not later than five Business Days after such repatriation could be made) applied (net of additional taxes payable or reserved against as a result thereof) (whether or not repatriation actually occurs) in compliance with this Section 4.16 and (ii) to the extent that the Company has determined in good faith that repatriation of any of or all the Net Cash Proceeds of any such prohibited or delayed Asset Sale would have a material adverse tax cost consequence with respect to such Net Cash Proceeds (which for the avoidance of doubt, may include, but is not limited to, any prepayment whereby doing so the Company, any Restricted Subsidiary or any of their respective affiliates and/or equity partners would incur a tax liability, including as a result of a dividend or a deemed dividend, or a withholding tax), the Net Proceeds so affected may be retained by the applicable Subsidiary. The non-application of any prepayment amounts as a consequence of the foregoing provisions will not, for the avoidance of doubt, constitute a Default or an Event of Default. The Trustee shall be entitled to conclusively rely on an Officer’s Certificate from the Company to the effect that applicable law will not permit repatriation of such amounts to the United States.

Section 4.17                             Covenant Termination.

(a)                                 If on any date:

(1)                           the Notes have an Investment Grade Rating from both of the Rating Agencies; and

(2)                           no Default or Event of Default has occurred and is continuing under this Indenture,

then, beginning on that day and continuing at all times thereafter regardless of any subsequent changes in the rating of the Notes, the Company and its Restricted Subsidiaries will not be subject to Sections 4.08, 4.09, 4.11, 4.12, 4.14, 4.16 and 5.01(a)(4).

(b)                                 The Company will provide the Trustee and the Paying Agent an Officer’s Certificate upon which the Trustee and Paying Agent can conclusively rely that the Notes are given Investment Grade Ratings.

Section 4.18                             Payment of Additional Amounts

(a)                                 All payments by the Company in respect of the Notes or the Guarantors in respect of the Note Guarantees will be made without withholding or deduction for or on account of any present or future taxes, duties, assessments, or other governmental charges of whatever nature imposed or levied by or on behalf of the Company’s, a Guarantor’s or any successor’s jurisdiction of incorporation or the jurisdiction in which central management or control of the Company, such Guarantor or such successor, as applicable, is exercised, or in or through which payments are made in respect of the Notes or the Note Guarantees or, in each case, any political subdivision or governmental authority therein (each a ‘‘Relevant Taxing Jurisdiction’’), unless the Company, such Guarantor or such successor is compelled by law to deduct or withhold such taxes, duties, assessments, or governmental charges. In such event, the relevant payor will make such deduction or withholding, make payment of the amount so withheld to the appropriate governmental authority and pay such additional amounts (the ‘‘Additional Amounts’’) as may be necessary to ensure that the net amounts receivable by holders of Notes after such withholding or deduction shall equal the respective amounts of principal and interest (and premium, if any) which would

70

have been receivable in respect of the Notes in the absence of such withholding or deduction. No such Additional Amounts shall be payable:

(1) to, or to a third party on behalf of, a Holder or beneficial owner who is liable for such taxes, duties, assessments or governmental charges in respect of such Note by reason of the existence of any present or former connection between such Holder (or between a fiduciary, settlor, beneficiary, member or shareholder of such Holder, if such Holder is an estate, a trust, a partnership, or a corporation) or beneficial owner and the Relevant Taxing Jurisdiction, including, without limitation, such Holder (or such fiduciary, settlor, beneficiary, member or shareholder) or beneficial owner being or having been a citizen or resident thereof or being or having been engaged in a trade or business or present therein or having, or having had, a permanent establishment therein, other than the mere holding of the Note or enforcement of rights and the receipt of payments with respect to the Note;

(2) in respect of Notes surrendered (if surrender is required) more than 30 days after the Relevant Date except to the extent that payments under such Note would have been subject to withholding and the Holder or beneficial owner of such Note would have been entitled to such Additional Amounts, on surrender of such Note for payment on the last day of such period of 30 days;

(3) in respect of any tax that is imposed on a payment to an individual and is required to be made pursuant to any law implementing or complying with, or introduced in order to conform to, the European Council Directive 2003/48/EC or any other directive implementing the conclusions of the ECOFIN Council meeting of November 26-27, 2000 on the taxation of savings income;

(4) to, or to a third party on behalf of, a Holder or beneficial owner who is liable for such taxes, duties, assessments or other governmental charges by reason of such Holder’s or beneficial owner’s failure to comply with any certification, identification or other reporting requirement concerning the nationality, residence, identity or connection with the Relevant Taxing Jurisdiction, or a successor jurisdiction or applicable political subdivision or authority thereof or therein having power to tax, of such Holder or beneficial owner, if (a) compliance is required by such jurisdiction, or any political subdivision or authority thereof or therein having power to tax, as a precondition to, exemption from, or reduction in the rate of, the tax, duty, assessment or other governmental charge and (b) the Company or any Guarantor has given the Holders at least 30 days’ notice that Holders will be required to provide such certification or identification or comply with such other requirement;

(5) in respect of any estate, inheritance, gift, sales, transfer, excise or personal property or similar tax, assessment or governmental charge;

(6) in respect of any tax, assessment or other governmental charge which is payable other than by deduction or withholding from payments of principal of, premium, if any, or interest on the Note or by direct payment by the Company or any Guarantor in respect of claims made against the Company or any Guarantor; or

(7) in respect of any combination of the above.

(b)                                 The Company will at all times during the term of the Notes, while there is a Paying Agent in Luxembourg, maintain a Paying Agent in a European Union jurisdiction which does not impose a withholding tax or deduction on payments in accordance with Council Directive 2003/48/EC or

71

any other European Union directive implementing the conclusions of the ECOFIN Council meeting of November 26-27, 2000 on the taxation of savings income.

(c)                                  No Additional Amounts shall be paid with respect to any payment on a Note to a Holder who is a fiduciary, a partnership, a limited liability company or other than the sole beneficial owner of that payment to the extent that payment would be required by the laws of the Relevant Taxing Jurisdiction, or any political subdivision thereof to be included in the income, for tax purposes, of a beneficiary or settlor with respect to the fiduciary, a member of the partnership, an interest holder in the limited liability company or a beneficial owner who would not have been entitled to the Additional Amounts had that beneficiary, settlor, member, interest holder or beneficial owner been the Holder. The Company or applicable Guarantor, as the case may be, will provide the Trustee and Paying Agent with the official acknowledgement of the Relevant Taxing Jurisdiction (or, if such acknowledgement is not available, other reasonable documentation) evidencing the payment of any taxes, duties, assessments or other government charges in respect of which the Company or such Guarantor, as the case may be, has paid any Additional Amounts. Copies of such documentation will be made available by the Trustee to the Holders or beneficial owners of the Notes, as applicable, upon request therefor.

(d)                                 At least 30 days prior to each date on which any payment under or with respect to the Notes is due and payable (unless such obligation to pay Additional Amounts arises shortly before or after the 30th day prior to such date, in which case it shall be promptly thereafter), if the Company or applicable Guarantor, as the case may be, will be obligated to pay Additional Amounts with respect to such payment, the Company will deliver to the Trustee and Paying Agent an Officer’s Certificate stating the fact that such Additional Amounts will be payable and the amounts so payable and will set forth such other information necessary to enable the Paying Agent to remit such Additional Amounts to Holders of Notes on the payment date. Each such Officer’s Certificate shall be relied upon until receipt of a new Officer’s Certificate addressing such matters.

(e)                                  The Company will pay any stamp, issue, excise, property, registration, documentary or other similar taxes and duties, including interest and penalties, imposed by a Relevant Taxing Jurisdiction in respect of the creation, issue, delivery, registration and offering of the Notes or the execution of the Notes, the Note Guarantees or this Indenture. The Company will also pay and indemnify each of the Trustee, the Paying Agent and the Holders and beneficial owners of the Notes from and against all court taxes or other taxes and duties, including interest and penalties, paid by any of them in any jurisdiction in connection with any action permitted to be taken by the Holders and beneficial owners to enforce the Company’s obligations under the Notes.

(f)                                   Any reference in this Indenture or the Notes to principal, interest or any other amount payable in respect of the Notes by the Company or the Note Guarantees by any Guarantor will be deemed also to refer to any Additional Amount, unless the context requires otherwise, that may be payable with respect to that amount under the obligations referred to in this Section 4.18.

(g)                                  The obligations of this Section 4.18 shall survive the termination or discharge of this Indenture.

Section 4.19                             Listing.

In the event that the Notes are listed on the Luxembourg Stock Exchange for trading on the Euro MTF Market, the Company will use its best efforts to maintain such listing; provided that if, as a result of the European Union regulated market amended Directive 2004/109/EC (the “Transparency Directive”) or any legislation implementing the Transparency Directive or other directives or legislation, the Company could be required to publish financial information either more regularly than it otherwise would be required to or according to accounting principles which are materially different from the

72

accounting principles which the Company would otherwise use to prepare its published financial information, the Company may delist the Notes from the Luxembourg Stock Exchange in accordance with the rules of the exchange and will use its best efforts to obtain an alternative admission to listing, trading and/or quotation for the Notes on a different section of the Luxembourg Stock Exchange or by such other listing authority, stock exchange and/or quotation system inside or outside the European Union as the Company’s Board of Directors may decide.

However, a Default under clauses (5) of this Section 6.01(a) will not constitute an Event of Default until the Trustee (acting at the direction of holders of at least 25.0% in outstanding principal amount of the Notes) or the holders of at least 25.0% in principal amount of the Notes outstanding notify the Company and the Trustee of the Default and the Company does not cure such Default within the time specified in clause (5) of this Section 6.01(a) after receipt of such notice.

(b)                                 The Trustee is not to be charged with knowledge of any Default or Event of Default or knowledge of any cure of any Default or Event of Default unless either (i) a Responsible Officer of the Trustee with direct responsibility for this Indenture has actual knowledge of such Default or Event of Default or (ii) written notice of any event which is in fact a Default or Event of Default has been given to the Trustee at its corporate trust office by the Company, any Guarantor or any Holder, such notice identifying this Indenture and the Company.

Section 6.02                             Acceleration.

(a)                                 If an Event of Default (other than an Event of Default described in clauses (8), (9) or (10) of Section 6.01(a)) occurs and is continuing, the Trustee (acting at the direction of holders of at least 25.0% in outstanding principal amount of the Notes) by written notice to the Company, specifying the Event of Default, or the Holders of at least 25% in principal amount of the then outstanding Notes, by written notice to the Company and the Trustee, may, declare the principal, premium, if any, and accrued and unpaid interest, if any, on all the Notes to be due and payable.  Upon such declaration, such principal, premium, if any, and accrued and unpaid interest, if any, will be due and payable.

(b)                                 In case an Event of Default described in clauses (8), (9) or (10) of Section 6.01(a) occurs and is continuing, the principal of, premium, if any, and accrued and unpaid interest, if any, on all the Notes will become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders.

(c)                                  In the event of a declaration of acceleration of the Notes because an Event of Default described in clause (6) of Section 6.01(a) has occurred and is continuing, the declaration of acceleration of the Notes shall be automatically annulled if:

(1)                                 the default triggering such Event of Default pursuant to clause (6) of Section 6.01(a) shall be remedied or cured by the Company or a Restricted Subsidiary or waived by the

77

holders of the relevant Debt within 20 days after the declaration of acceleration with respect thereto; and

(2)                                 (A) the annulment of the acceleration of the Notes would not conflict with any judgment or decree of a court of competent jurisdiction and (B) all existing Events of Default, except nonpayment of principal, premium, if any, or interest on the Notes that became due solely because of the acceleration of the Notes, have been cured or waived.

(d)                                 The Holders of a majority in principal amount of the outstanding Notes may waive all past Events of Default (except with respect to nonpayment of principal, premium or interest) and rescind any acceleration with respect to the Notes and its consequences if (1) such rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) all existing Events of Default, other than the nonpayment of the principal of, premium, if any, and interest on the Notes that have become due solely by such declaration of acceleration, have been cured or waived.

Section 6.03                             Other Remedies.

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

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

Section 6.04                             Waiver of Past Defaults.

The Holders of a majority in principal amount of the outstanding Notes by written notice to the Trustee may on behalf of all Holders waive any existing Default or Event of Default and its consequences hereunder, except:

(1)                                 a continuing Default or Event of Default in the payment of the principal, premium, if any, or interest on any Note held by a non-consenting Holder (including in connection with an Asset Sale Offer or a Change of Control Offer); and

(2)                                 a Default or Event of Default with respect to a provision that under Section 9.02 cannot be amended without the consent of each Holder affected,

provided that, subject to Section 6.02, 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.  Upon any such waiver, such Default or Event of Default shall cease to exist, and, if applicable, 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 outstanding Notes may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee.  However, the Trustee may refuse to follow any

78

direction that conflicts with law, this Indenture, the Notes, the Security Documents or any Note Guarantee, or that the Trustee determines in good faith is unduly prejudicial to the rights of any other Holder or that would involve the Trustee in personal liability.  Prior to taking any action hereunder or under the Security Documents, the Trustee shall be entitled to indemnification reasonably satisfactory to it against all losses and expenses caused by taking or not taking such action.

Section 6.06                             Limitation on Suits.

Subject to Section 6.07, no Holder may pursue any remedy with respect to this Indenture or the Notes unless:

(1)                                 such Holder has previously given the Trustee notice that an Event of Default is continuing;
